NOVKO, Denis
Znanost i poezija [Elektronička građa] : pojam nove mitologije u Schellingovoj filozofiji / Denis Novko.
Tema broja: Schellingova filozofija - izabrani problemi. - Bibliografske bilješke uz tekst. - Sažetak ; Abstract. - Nužna upućenost filozofije na poeziju u Schellingovoj se filozofiji najjasnije pokazuje time što on u Sistemu transcendentalnog idealizma filozofiji pripisuje estetičku funkciju. Poezija je za Schellinga, prije svega, ono što prethodi znanosti. U kružnom se kretanju, u vidu sistema znanosti, na svom završetku znanost ponovno mora vratiti u ono iz čega je proizašla. Ono što vodi znanost k ponovnom povratku poeziji može se, prema Schellingovu shvaćanju, pronaći u prirodi i njezinoj organizaciji. Organizacija prirode u najstarijoj filozofiji pjesničkim je izričajem bila izražena u formi priče. Mitološka je forma za Schellinga stoga srednji član povratka znanosti k poeziji. - The necessary relation of philosophy and poetry in Schellingʼs philosophy is most clearly visible in the way he attributes the aesthetic function to philosophy in his work System of transcendental idealism. For Schelling, poetry is what precedes science, which, in terms of the system of science, must in its circular motion return at its completion to what it came from. What leads science to the return to poetry can be found, according to Schelling, in nature and in the way that it is organised. The organisation in nature was in ancient philosophy portrayed through poetic expression in the form of stories. For Schelling, the mythological form is therefore the middle ground, which leads to the return of science to poetry.

RUNJE, Petar
Glagoljaši u Splitu u 15. stoljeću [Elektronička građa] / Petar Runje.
Bibliografske bilješke uz tekst. - Sažetak ; Summary. - U članku se iznose podaci pronađeni u bilježničkim spisima iz 15. stoljeća o knjizi na hrvatskom jeziku u osobnoj knjižnici splitskoga arhiprezbitera i o nekim svećenicima glagoljašima tada nastanjenima u gradu Splitu. Posebno je značenje tih podataka u tome što neki drugi iz srednjega vijeka koji bi svjedočili o nazočnosti i djelovanju glagoljaša u samom sjedištu Splitske nadbiskupije, nisu do sada pronađeni. - The author emphasizes the fact that the historians so far have not discovered written traces of the presence and activities of Glagolitic priests in the centuries of the Middle Ages in the city of Split, although some traces from the area of the Archdiocese of Split have long been known. Therefore, rare information found in the writings of the 15th century is a valuable historical testimony. In this paper, they are recorded and carefully explained. There is an interesting and at least somewhat justifiable assumption about the connection between the Glagolitic priests from the area of present-day western Bosnia and Split and the area of the Archdiocese of Split.

ENNAJI, Fatima Zohra
A crowdsourcing based framework for sentiment analysis [Elektronička građa] : a product reputation / F. Z. [Fatima Zohra] Ennaji, A. [Abdelaziz] El Fazziki, H. [Hasna] El Alaoui El Abdallaoui, H. [Hamada] El Kabtane. - Ilustr.
Bibliografija: 33 jed. - Abstract. - As social networking has spread, people started sharing their personal opinions and thoughts widely via these online platforms. The resulting vast valuable data represent a rich source for companies to deduct their products’ reputation from both social media and crowds’ judgments. To exploit this wealth of data, a framework was proposed to collect opinions and rating scores respectively from social media and crowdsourcing platform to perform sentiment analysis, provide insights about a product and give consumers’ tendencies. During the analysis process, a consumer category (strict) is excluded from the process of reaching a majority consensus. To overcome this, a fuzzy clustering is used to compute consumers’ credibility. The key novelty of our approach is the new layer of validity check using a crowdsourcing component that ensures that the results obtained from social media are supported by opinions extracted directly from real-life consumers. Finally, experiments are carried out to validate this model (Twitter and Facebook were used as data sources). The obtained results show that this approach is more efficient and accurate than existing solutions thanks to our two-layer validity check design.

TARASIA, Nachiketa
A level-wise periodic tree construction mechanism for sleep scheduling in WSN [Elektronička građa] / Nachiketa Tarasia, Amulya Ratna Swain, Soham Roy, Udit Narayana Kar. - Graf. prikazi.
Bibliografija: 36 jed. - Abstract. - The wireless sensor network (WSN) has been extensively used to monitor and control the natural ecosystem on a large scale like air quality, natural life, etc. Low battery power,low storage, and limited processing ability are the most critical areas of concern in WSN. To reduce energy utilization, the sensor nodes in WSN work in a cyclic process between active and sleep mode. A certain number of nodes are chosen active and they are responsible for sensing as well as data transmission and rest of the nodes are gone to sleep. In order to lengthen the lifetime of network, in this paper we proposed a level wise periodic tree construction algorithm that uses a specific set of nodes to participate in tree construction, instead of all the nodes, to minimize the energy consumption. In this proposed approach, the main idea is to put the nodes, which are currently active and have already spent a significant amount of energy, to sleep mode, while giving chances to the leaf nodes, which has comparatively spent less energy, to become an active node and maintain connectivity. The performance of the proposed protocol is evaluated using the Castalia simulator. The simulation results show that the proposed level-wise periodic tree construction approach increases the durability of the network in conjunction with the non-level approach.

GARMANI, Hamid
A non-cooperative game-theoretic framework for sponsoring content in the Internet market [Elektronička građa] / Hamid Garmani, Driss Ait Omar, Mohamed El Amrani, Mohamed Baslam, Mostafa Jourhmane. - Graf. prikazi.
Bibliografija: 36 jed. - Summary. - Data traffic demand over the Internet is increasing rapidly, and it is changing the pricing model between internet service providers (ISPs), content providers (CPs) and end users. One recent pricing proposal is sponsored data plan, i.e., when CP negotiates with the ISP on behalf of the users to remove the network subscription fees so as to attract more users and increase the number of advertisements. As such, a key challenge is how to provide proper sponsorship in the situation of complex interactions among the telecommunication actors, namely, the advertisers, the content provider, and users. To answer those questions, we explore the potential economic impacts of this new pricing model by modeling the interplay among the advertiser, users, and the CPs in a game theoretic framework. The CP may have either a subscription revenue model (charging end-users) or an advertisement revenue model (charging advertisers). In this work, we design and analyze the interaction among CPs having an advertisement revenue as a non-cooperative game, where each CP determines the proportion of data to sponsor and a level of credibility of content. In turn, the end-users demand for the content of a CP depends not only on their strategies but also upon those proposed by all of its competitors. Through rigorous mathematical analysis, we prove the existence and uniqueness of the Nash equilibrium. Based on the analysis of the game properties, we propose an iterative algorithm, which guarantees to converge to the Nash equilibrium point in a distributed manner. Numerical investigation shows the convergence of a proposed algorithm to the Nash equilibrium point and corroborates the fact that sponsoring content may improve the CPs outcome.

VIEIRA, Samuel Terra
A speech quality classifier based on Tree-CNN algorithm that considers network degradations [Elektronička građa] / Samuel Terra Vieira, Renata Lopes Rosa, Demóstenes Zegarra Rodríguez. - Ilustr.
Bibliografija: 67 jed. - Abstract. - Many factors can affect the users’ quality of experience (QoE) in speech communication services. The impairment factors appear due to physical phenomena that occur in the transmission channel of wireless and wired networks. The monitoring of users’ QoE is important for service providers. In this context, a non-intrusive speech quality classifier based on the Tree Convolutional Neural Network (Tree-CNN) is proposed. The Tree-CNN is an adaptive network structure composed of hierarchical CNNs models, and its main advantage is to decrease the training time that is very relevant on speech quality assessment methods. In the training phase of the proposed classifier model, impaired speech signals caused by wired and wireless network degradation are used as input. Also, in the network scenario, different modulation schemes and channel degradation intensities, such as packet loss rate, signal-to-noise ratio, and maximum Doppler shift frequencies are implemented. Experimental results demonstrated that the proposed model achieves significant reduction of training time, reaching 25% of reduction in relation to another implementation based on DRBM. The accuracy reached by the Tree-CNN model is almost 95% for each quality class. Performance assessment results show that the proposed classifier based on the Tree-CNN overcomes both the current standardized algorithm described in ITU-T Rec. P.563 and the speech quality assessment method called ViSQOL.

KARAMACHOSKI, Jovan
Blockchain-based application for certification management [Elektronička građa] / Jovan Karamachoski, Ninoslav Marina, Pavel Taskov. - Graf. prikazi.
Bibliografija: 23 jed. - Summary. - Blockchain technology will bring a disruption in plenty of industries and businesses. Recently it proved the robustness, immutability, auditability, in many crucial practical applications. The blockchain structure offers traceability of actions, alterations, alerts, which is an important property of a system needed for development of sustainable technologies. A crucial part of the blockchain technology regarding the optimization of the processes is the smart contract. It is a self-executable computer code, open and transparent, encoding the terms of a regular contract. It is able to automate the processes, thus decreasing the human-factor mistakes or counterfeits. In this paper, we are presenting the feasibility of the blockchain technology in the certification processes, with an application developed for university diploma certification. The example is easily transferable in other areas and business models such as logistics, supply chain management, or other segments where certification is essential.

Context-aware kubernetes scheduler for edge-native applications on 5G [Elektronička građa] / Michael Chima Ogbuachi, Anna Reale, Péter Suskovics, Benedek Kovács. - Ilustr.
Bibliografija: 47 jed. - Abstract. - This paper is an extension of work originally presented in SoftCOM 2019 [1]. The novelty of this work reside in its focused improvement of our scheduling algorithm towards its usage on a real 5G infrastructure. Industrial IoT applications are often designed to run in a distributed way on the devices and controller computers with strict service requirements for the nodes and the links between them. 5G, especially in concomitance with Edge Computing, will provide the desired level of connectivity for these setups and it will permit to host application run-time components in edge clouds. However, allocation of the edge cloud resources for Industrial IoT (IIoT) applications, is still commonly solved by rudimentary scheduling techniques (i.e. simple strategies based on CPU usage and device readiness, employing very few dynamic information). Orchestrators inherited from the cloud computing, like Kubernetes, are not satisfying to the requirements of the aforementioned applications and are not optimized for the diversity of devices which are often also limited in capacity. This design is especially slow in reacting to the environmental changes. In such circumstances, in order to provide a proper solution using these tools, we propose to take the physical, operational and network parameters (thus the full context of the IIoT application) into consideration, along with the software states and orchestrate the applications dynamically.

LAKHAL, Said
Decentralization of services through three tiers in Wireless Body Area Networks [Elektronička građa] / Said Lakhal, Zouhair Guennoun. - Ilustr., graf. prikazi.
Bibliografija: 17 jed. - Summary. - The Wireless Body Area Network (WBAN) contains a set of sensors, placed in the patient’s environment, to detect the vital signs and transmit the results towards the relevant services that interact in urgent cases. The present work exposes a functional WBAN architecture formed by three layers: closest, intermediate and farthest. The closest layer senses the chemical and biological signs. If the case is normal, or it can be locally regulated, the service stops there; else the intermediate service, namely the local hospital, is consulted to make treatments. Therefore, the patient will be transported into the hospital for examinations. If this condition is established the processus stopped there, otherwise, the request of help from an outside hospital becomes necessary. This request passes through a manager that supervises a network of hospitals and looks for a free place to welcome the patient. After the localization of a hospital, its coordinates will be forwarded into the customer hospital, for transporting the patient. The simulation results show that this design increases the patient’s probability of healing and maximizes the use of the available resources, relative to the centralization of services at a single layer or at two layers.

Detection of Escherichia coli bacteria in water using deep learning [Elektronička građa] : a faster R-CNN approach / Hüseyin Yanik, Ahmet Hilmi Kaloğlu, Evren Değirmenci. - Ilustr.
Bibliografija: 46 jed. - Abstract. - Considering its importance for vital activities, water and particularly drinking water should be clean and should not contain disease-causing bacteria. One of the pathogenic bacteria found in water is the bacterium Escherichia coli (E. coli). In the commonly used method for the detection of E. coli bacteria, the bacteria samples distilled from the water sample are seeded in endo agar medium and the change in the color of the medium as a result of the metabolic activities of the bacteria is examined with the naked eye. This color change can be seen with the human eye in approximately 22 ± 2 hours. In this study, a new bacteria detection scheme is proposed – using deep learning to detect E. coli bacteria both in shorter time and in practical way. The proposed technique is tested with experimentally collected data. Results show that the detection of bacteria can be done automatically within 6-10 hours with the proposed method.

An efficient image fusion of visible and infrared band images using integration of anisotropic diffusion and discrete wavelet transform [Elektronička građa] / Binal Panchotiya, Dippal Israni, Ritesh Patel. - Ilustr.
Bibliografija: 21 jed. - Anstract. - Image fusion is a technique that combines two source images to generate more informative target image. It plays a vital role in medical image investigation, military, navigation, etc. visible images offer efficient texture detail with high spatial resolution. In contrast, based on the radiation difference infrared images are able to differentiate target from their background. There are many algorithms that helps in preserving the edges of image like Bilateral filter, anisotropic diffusion (ADF). This paper integrates Anisotropic Diffusion and Karhunen-Loeve (KL)Transformation with discrete wavelet transform (DWT). In proposed Method, DWT decomposes into four sub-bands. ADF is applied on approximation sub-band and absolute maximum selection is applied on other three sub-bands. ADF decomposes the image into detailed layer and base layer. Base layer and Detailed layer are calculated using Kl- Transformation and linear combination respectively. Once fusion is done, inverse DWT is applied on all sub-bands. The experimental outcomes depict that the offered approach result with sharp edges of the image. The proposed algorithm is evaluated on standard dataset Like Duine_Sequence, Tree_sequence, Street dataset. Standard metrics like Average Gradients and Spatial Frequency metrics are used to evaluate the performance of the image.

Evaluation of ZigBee topology effect on throughput and End to End delay due to different transmission bands for IoT applications [Elektronička građa] / Yehia R. Hamdy, Ahmed I Alghannam. - Ilustr., graf. prikazi.
Bibliografija: 12 jed. - Summary. - ZigBee is widely used in wireless network in Internet of Things (IoT) applications to remotely sensing and automation due to its unique characteristics compared to other wireless networks. According to ZigBee classification of IEEE 802.15.4 standard, the network consists of four layers. The ZigBee topology is represented in second layer. Furthermore, the ZigBee topology consists of three topologies, star, tree and mesh. Also there are many transmission bands allowed in physical layer, such as 2.4 GHz, 915 MHz, 868 MHz. The aim of this paper is to evaluate the effect of ZigBee topologies on End to End delay and throughput for different transmission bands. Riverbed Modeler is used to simulate multiple ZigBee proposed scenarios and collect the results. The results of the study recommend which topology should be used at each transmission band to provide lowest End to End delay or obtain maximum throughput, which is case sensitive in some IoT applications that required for example minimum delay time or sending high amount of data.

An event-based local action paradigm to improve energy efficiency in queriable wireless sensor actuator networks [Elektronička građa] / René Bergelt, Wolfram Hardt. - Graf. prikazi.
Bibliografija: 29 jed. - Summary. - Wireless sensor networks (WSN) are deployed in a multitude of applications both in industrial and academic fields. In recent years, due to the emerge of Internet of Things (IoT) technologies and Vehicle2X communication scenarios, novel challenges for wireless sensor network platforms - regarding hardware and software - arose. Thus, challenges known from big data processing have reached the WSN scope and consequently approaches and methods have been devised to handle these. One such approach is queriable wireless sensor networks which enable their users the specification of sensing tasks in a declarative way without the need to re-program nodes in case the application requirements change. As many current WSN applications feature active parts with which nodes can directly influence their environment, the term wireless sensor actuator networks (WSAN) has been coined, setting such networks apart from solely passively measuring networks.In this article, we will present a short introduction to big data processing in wireless sensor networks which motivates the usage of queriable networks. We will show that in order to enable a WSAN to carry out actions energy-efficiently and in a timely manner, an event-based action model is favorable. Additionally, we will demonstrate how such an event system can be used to improve sub query performance in WSNs. We conclude with an evaluation regarding the benefit of combining this approach with wake-up receiver technologies based on a qualitative energy efficiency definition for WSN.

Human retina based identification system using gabor filters and GDA technique [Elektronička građa] / Shahad A. Sultan, Mayada Faris Ghanim. - Ilustr.
Bibliografija: 31 jed. - Abstract. - A biometric authentication system provides an automatic person authentication based on some characteristic features possessed by the individual. Among all other biometrics, human retina is a secure and reliable source of person recognition as it is unique, universal, lies at the back of the eyeball and hence it is unforgeable. The process of authentication mainly includes pre-processing, feature extraction and then features matching and classification. Also authentication systems are mainly appointed in verification and identification mode according to the specific application. In this paper, preprocessing and image enhancement stages involve several steps to highlight interesting features in retinal images. The feature extraction stage is accomplished using a bank of Gabor filter with number of orientations and scales. Generalized Discriminant Analysis (GDA) technique has been used to reduce the size of feature vectors and enhance the performance of proposed algorithm. Finally, classification is accomplished using k-nearest neighbor (KNN) classifier to determine the identity of the genuine user or reject the forged one as the proposed method operates in identification mode. The main contribution in this paper is using Generalized Discriminant Analysis (GDA) technique to address ‘curse of dimensionality’ problem. GDA is a novel method used in the area of retina recognition.

An improved image segmentation system [Elektronička građa] : a cooperative multi-agent strategy for 2D/3D medical images / Hanane Allioui, Mohamed Sadgal, Aziz El Fazziki. - Ilustr., graf. prikazi.
Bibliografija: 43 jed. - Summary. - In this paper, we present a solution-based cooperation approach for strengthening the image segmentation.This paper proposes a cooperative method relying on Multi-Agent System. The main contribution of this work is to highlight the importance of cooperation between the contour and region growing based on Multi-Agent System (MAS). Consequently, agents’ interactions form the main part of the whole process for image segmentation. Similar works were proposed to evaluate the effectiveness of the proposed solution. The main difference is that our Multi-Agent System can perform the segmentation process ensuring efficiency. Our results show that the performance indices in the system were higher. Furthermore, the integration of the cooperation paradigm allows to speed up the segmentation process. Besides, the tests reveal the robustness of our method by proving competitive results. Our proposal achieved an accuracy of 93,51%± 0,8, a sensitivity of 93,53%± 5,08 and a specificity rate of 92,64%± 4,01.

Improved white blood cells classification based on pre-trained deep learning models [Elektronička građa] / Ensaf H. Mohamed, Wessam H. El-Behaidy, Ghada Khoriba, Jie Li. - Ilustr., graf. prikazi.
Bibliografija: 35 jed. - Summary. - Leukocytes, or white blood cells (WBCs), are microscopic organisms that fight against infectious disease, bacteria, viruses, and others. The manual method to classify and count WBCs is tedious, time-consuming and may has inaccurate results, whereas the automated methods are costly. The objective of this work is to automatically identify and classify WBCs in a microscopic image into four types with higher accuracy. BCCD is the used dataset in this study, which is a scaled down blood cell detection dataset. BCCD is firstly pre-processed by passing through several processes such as segmentation and augmentation,then it is passed to the proposed model. Our model combines the privilege of deep models in automatically extracting features with the higher classification accuracy of traditional machine learning classifiers.The proposed model consists of two main layers; a shallow tuning pre-trained model and a traditional machine learning classifier on top of it. Here, ten different pretrained models with six different machine learning are used in this study. Moreover, the fully connected network (FCN) of pretrained models is used as a baseline classifier for comparison. The evaluation process shows that the hybrid between MobileNet-224 as feature extractor with logistic regression as classifier has a higher rank-1 accuracy with 97.03%. Besides, the proposed hybrid model outperformed the baseline FCN with 25.78% on average.

Performance and statistical analysis of stream ciphers in GSM communications [Elektronička građa] / Nagendar Yerukala, V. Kamakshi Prasad, Allam Apparao. - Graf. prikazi.
Bibliografija: 29 jed. - Abstract. - For a stream cipher to be secure, the keystream generated by it should be uniformly random with parameter 1/2.Statistical tests check whether the given sequence follow a certain probability distribution. In this paper, we perform a detailed statistical analysis of various stream ciphers used in GSM 2G,3G, 4G and 5G communications. The sequences output by these ciphers are checked for randomness using the statistical tests defined by the NIST Test Suite. It should also be not possible to derive any information about secret key and the initial state ofthe cipher from the keystream. Therefore, additional statisticaltests based on properties like Correlation between Keystreamand Key, and Correlation between Keystream and IV are also performed. Performance analysis of the ciphers also has been done and the results tabulated. Almost all the ciphers pass thetests in the NIST test suite with 99% confidence level. For A5/3stream cipher, the correlation between the keystream and key is high and correlation between the keystream and IV is low when compared to other ciphers in the A5 family.

Performance evaluation in single or multi-cluster C-RAN supporting quasi-random traffic [Elektronička građa] / Iskanter-Alexandros Chousainov, Ioannis Moscholios, Alexandros Kaloxylos, Michael Logothetis. - Graf. prikazi.
Bibliografija: 44 jed. - Summary. - In this paper, a cloud radio access network (C-RAN) is considered where the remote radio heads (RRHs) are separated from the baseband units (BBUs). The RRHs in the C-RAN are grouped in different clusters according to their capacity while the BBUs form a centralized pool of computational resource units. Each RRH services a finite number of mobile users, i.e., the call arrival process is the quasi-random process. A new call of a single service-class requires a radio and a computational resource unit in order to be accepted in the C-RAN for a generally distributed service time. If these resource units are unavailable, then the call is blocked and lost. To analyze the multi-cluster C-RAN, we model it as a single-rate loss system, show that a product form solution exists for the steady state probabilities and propose a convolution algorithm for the accurate determination of congestion probabilities. The accuracy of this algorithm is verified via simulation. The proposed model generalizes our recent model where the RRHs in the C-RAN are grouped in a single cluster and each RRH accommodates quasi-random traffic.

PList-based divide and conquer parallel programming [Elektronička građa] / Virginia Niculescu, Darius Bufnea, Adrian Sterca. - Graf. prikazi.
Bibliografija: 23 jed. - Summary. - This paper details an extension of a Java parallel programming framework – JPLF. The JPLF framework is a programming framework that helps programmers build parallel programs using existing building blocks. The framework is based on {\em PowerLists} and PList Theories and it naturally supports multi-way Divide and Conquer. By using this framework, the programmer is exempted from dealing with all the complexities of writing parallel programs from scratch. This extension to the JPLF framework adds PLists support to the framework and so, it enlarges the applicability of the framework to a larger set of parallel solvable problems. Using this extension, we may apply more flexible data division strategies. In addition, the length of the input lists no longer has to be a power of two – as required by the PowerLists theory. In this paper we unveil new applications that emphasize the new class of computations that can be executed within the JPLF framework. We also give a detailed description of the data structures and functions involved in the PLists extension of the JPLF, and extended performance experiments are described and analyzed.

Privacy preserving sensitive data publishing using (k,n,m) anonymity approach [Elektronička građa] / Nancy Victor, Daphne Lopez. - Graf. prikazi.
Bibliografija: 35 jed. - Abstract. - Open Science movement has enabled extensive knowledge sharing by making research publications, software, data and samples available to the society and researchers. The demand for data sharing is increasing day by day due to the tremendous knowledge hidden in the digital data that is generated by humans and machines. However, data cannot be published as such due to the information leaks that can occur by linking the published data with other publically available datasets or with the help of some background knowledge. Various anonymization techniques have been proposed by researchers for privacy preserving sensitive data publishing. This paper proposes a (k,n,m) anonymity approach for sensitive data publishing by making use of the traditional k-anonymity technique. The selection of quasi identifiers is automated in this approach using graph theoretic algorithms and is further enhanced by choosing similar quasi identifiers based on the derived and composite attributes. The usual method of choosing a single value of ‘k’ is modified in this technique by selecting different values of ‘k’ for the same dataset based on the risk of exposure and sensitivity rank of the sensitive attributes. The proposed anonymity approach can be used for sensitive big data publishing after applying few extension mechanisms. Experimental results show that the proposed technique is practical and can be implemented efficiently on a plethora of datasets.

Qualitative acceptance model of augmented reality from the perspective of personalists [Elektronička građa] / Sabrina Romina Sorko, Joachim Komar. - Ilustr.
Bibliografija: 40 jed. - Abstract. - Smart devices and the corresponding new technologies have established themselves within our society. Since the release of the smartphone game Pokémon Go, the field of augmented reality (AR) - the enrichment of reality with information, realized by smart devices such as tablets, data glasses or smartphones - has been experiencing an upswing. Additionally, the industry is starting to integrate AR applications to increase efficiency. In this respect, HR managers play a key role in the implementation of such technology. They maintain direct contact with employees, have an overview of the entire company and thus are often responsible for change processes. The paper analyses the potential of AR within a company from a personalist’s point of view and discusses critical factors both in theory and practice. The paper validates the technological possibilities and shows results from a qualitative analysis from focus group discussions. The qualitative acceptance model displays factors influencing the implementation of AR.

Security enhancement in cloud environment using secure secret key sharing [Elektronička građa] / Sakshi Chhabra, Ashutosh Kumar Singh. - Ilustr., graf. prikazi.
Bibliografija: 36 jed. - Summary. - Securing the data in distributed cloud system is considered one of the major concern for the cloud customers who faces security risks. The data leakage or data tampering are widely used by attackers to extract the private information of other users who shares the confidential data through virtualization. This paper presents Secure Secret Sharing (SSS) technique which is being recognized as one of the leading method to secure the sensitive data. It shares encrypted data over cloud and generated secret key is split into different parts distributed to qualified participants (Qn) only which is analyzed by malicious checkers. It verifies the clients based on their previous performances, whether these users proved to be authorized participant or not. The key computation is evaluated by the Key handler (KH) called trusted party which manages authorized control list, encryption/decryption and reconstruction of key shares. The Lagrange’s interpolation method is used to reconstruct the secret from shares. The experimental results shows that the proposed secure data sharing algorithm not only provides excellent security and performance, but also achieves better key management and data confidentiality than previous countermeasures. It improves the security by using secure VM placement and evaluated based on time consumption and probability computation to prove the efficacy of our algorithm. Experiments are performed on cloudsim based on following parameters i.e. time computation of key generation; response time and encryption/decryption. The experimental results demonstrate that this method can effectively reduce the risks and improves the security and time consumption upto 27.81% and 43.61% over existing algorithms.

The simulation model of a student restaurant [Elektronička građa] / Zvonimir Mihaljevic, Goran Dukic. - Ilustr.
Bibliografija: 5 jed. - Abstract. - This paper features a simulation model of the FSB canteen. The data required for the simulation was collected through direct observation of the canteen during the busiest time of the day, that is, lunchtime. The simulation model was verified and validated based on the collected data. The model and the results of the simulation were presented. In order to reduce the waiting time, two modifications of the existing model were proposed and simulation models for both cases were also developed. After simulating the modified models, in order to determine the effects of the proposed modifications, the obtained results were analyzed and compared with the results of the existing system.

Speech quality classifier model based on DBN that considers atmospheric phenomena [Elektronička građa] / Marielle Jordane da Silva, Dick Carrillo Melgarejo, Renata Lopes Rosa, Demóstenes Zegarra Rodríguez. - Graf. prikazi.
Bibliografija: 55 jed. - Summary. - Current implementations of 5G networks consider higher frequency range of operation than previous telecommunication networks, and it is possible to offer higher data rates for different applications. On the other hand, atmospheric phenomena could have a more negative impact on the transmission quality. Thus, the study of the transmitted signal quality at high frequencies is relevant to guaranty the user ́s quality of experience. In this research, the recommendations ITU-R P.838-3 and ITU-R P.676-11 are implemented in a network scenario, which are methodologies to estimate the signal degradations originated by rainfall and atmospheric gases, respectively. Thus, speech signals are encoded by the AMR-WB codec, transmitted and the perceptual speech quality is evaluated using the algorithm described in ITU-T Rec. P.863, mostly known as POLQA. The novelty of this work is to propose a non-intrusive speech quality classifier that considers atmospheric phenomena. This classifier is based on Deep Belief Networks (DBN) that uses Support Vector Machine (SVM) with radial basis function kernel (RBF-SVM) as classifier, to identify five predefined speech quality classes. Experimental Results show that the proposed speech quality classifier reached an accuracy between 92% and 95% for each quality class overcoming the results obtained by the sole non-intrusive standard described in ITU-T Recommendation P.563. Furthermore, subjective tests are carried out to validate the proposed classifier performance, and it reached an accuracy of 94.8%.

Taking into account material damping in seismic analysis of structures [Elektronička građa] / Maria S. Barabash, Bogdan Y. Pisarevskyi, Yaroslav Bashynskyi. - Graf. prikazi.
Bibliografija: 11 jed. - Abstract. - The purpose of this paper is to justify that it is necessary to take into account physical and mechanical properties of soil and different materials of erected structures for damping vibrations in dynamic loads, and to suggest tools for modelling the damping effect (natural or engineering induced) between foundation and soil. A technique is suggested for modelling the behavior of structure in time history analysis taking into account material damping. When solving this problem, the following results were obtained: the physical meaning of material damping was described; Rayleigh damping coefficients were computed through modal damping coefficients. Numerical analysis was carried out for the structure together with soil in earthquake load. Time history analysis was carried out for the problem. Peak values of displacement, speed and acceleration at the roof levels were compared. Analysis results were compared (with and without taking into account material damping). Significant influence of damping on the stress-strain state of the structure has been confirmed.

Trends towards IOT in Egypt [Elektronička građa] : cloud computing system implementation in Egypt : challenges and benefits / Mai Salah ElDine Mohamed ElSayed. - Ilustr.
Bibliografija: 21 jed. - Abstract. - This research aims to investigate the benefits of implementing the cloud computing system over the currently used IT system, as well the challenges of applying Cloud computing that companies in Egypt could face. This research applies mixed methods of research. Both qualitative and quantitative methods of research are used in the form of semi-structured interviews and questionnaires, respectively. The semi-structured interview was targeting the supply chain and IT managers of three different companies at Coca Cola Egypt, Nestle Egypt and Carrefour Egypt. A SWOT analysis was conducted to serve as a guide to many companies in Egypt that are willing to implement such a system and can then avoid the weakness points and the threats that they could be faced with during the implementation. The importance of this research adds to the literature by focusing on the application of IOT in Egypt in terms of the implementation of a cloud computing system in Egypt and it analyzes whether it could increase the efficiency of the companies in Egypt.

MAIER, Hans Thomas
Validation of a lean smart maintenance maturity model [Elektronička građa] / Hans Thomas Maier, Oliver Schmiedbauer, Hubert Biedermann. - Graf. prikazi.
Bibliografija: 30 jed. - Summary. - Rising complexity in industrial asset and maintenance management due to more volatile business environments and megatrends like Industry 4.0 has led to the need for a new perspective on these management domains. The Lean Smart Maintenance (LSM) philosophy, which focuses on both the efficient (lean) and the learning (smart) organization was introduced during the past few years, and a corresponding maturity model (MM) has been developed to guide organizations on their way to asset and maintenance excellence. This paper discusses use cases, in which the usability and the generic aspect of the LSM MM are validated by using data from three different asset management assessment projects in organizations with different types of production. Research results show that the LSM MM can be used as a basis for management system improvement, independent of production types such as one-of-a-kind industry, mass production and continuous production.

NOVAK, Roman
Viability of numerical full-wave techniques in telecommunication channel modelling [Elektronička građa] / Roman Novak. - Ilustr.
Bibliografija: 108 jed. - Abstract. - In telecommunication channel modelling the wavelength is small compared to the physical features of interest, therefore deterministic ray tracing techniques provide solutions that are more efficient, faster and still within time constraints than current numerical full-wave techniques. Solving fundamental Maxwell's equations is at the core of computational electrodynamics and best suited for modelling electrical field interactions with physical objects where characteristic dimensions of a computing domain is on the order of a few wavelengths in size. However, extreme communication speeds, wireless access points closer to the user and smaller pico and femto cells will require increased accuracy in predicting and planning wireless signals, testing the accuracy limits of the ray tracing methods. The increased computing capabilities and the demand for better characterization of communication channels that span smaller geographical areas make numerical full-wave techniques attractive alternative even for larger problems. The paper surveys ways of overcoming excessive time requirements of numerical full-wave techniques while providing acceptable channel modelling accuracy for the smallest radio cells and possibly wider. We identify several research paths that could lead to improved channel modelling, including numerical algorithm adaptations for large-scale problems, alternative finite-difference approaches, such as meshless methods, and dedicated parallel hardware, possibly as a realization of a dataflow machine.

Bibliografija: 54 jed. - Abstract. - This study is functional in terms of purpose and descriptive-exploratory in terms of doing research. The method of data collection is library and field studies using a questionnaire tool. Those with relevant postgraduate qualifications and at least ten years of working experience, especially management experience in the automotive industry with a sufficiently motivated executive background to participate were chosen. In the quantitative section, the experts include nine executives and senior experts in the automotive industry who were selected through snowballing. The most important dimensions and criteria of a sustainable world class manufacturing model are identified by a theoretical literature review and interviews with the experts, and they were then screened and localized with expert opinions and fuzzy Delphi techniques. After collecting data through a paired comparisons questionnaire, the data were analyzed by using a fuzzy-dimensional network analysis process hybrid technique. The findings of fuzzy DEMATEL indicated that the dimensions of "environmental", "economic" and "social" sustainability help in achieving sustainable world class manufacturing.

Entrepreneurial myths (or realities) and entrepreneurial intentions [Elektronička građa] / Davor Širola, Robert Strahinja, Nikola Novosel. - Graf. prikazi.
Bibliografija: 22 jed. - Summary ; Sažetak. - The development of modern entrepreneurship research began some 50 years ago. In the meantime, various definitions of entrepreneurship led to different interpretations of its scope, and subsequently, the entrepreneurial myths emerged. This topic was studied quite intensively in the 1980s and 1990s, and numerous results succeeded in demystifying most of the entrepreneurial myths. Despite that, the entrepreneurial myths persist and regularly appear on the web portals, media, and bloggers’ articles. On the other side, contemporary entrepreneurship textbooks include entrepreneurial myths as a lesson which could eliminate some obstacles for the nascent entrepreneurs. This study revealed that the entrepreneurial myths are somewhat present among younger examinees, nonentrepreneurs in Croatia, who have a low or medium level of education. Still, not even these demographic groups view those myths as realities. Further analysis pointed out that there is a statistically significant, although negative and weak correlation between the perception of entrepreneurial myths as myths (not as realities) and a higher level of entrepreneurial intentions. - Razvoj suvremenih istraživanja u području poduzetništva započeo je prije pedesetak godina. U međuvremenu, ponuđene su različite definicije poduzetništva koje su dovele do raznolikih interpretacija obuhvata poduzetništva te naposlijetku do nastanka poduzetničkih mitova. Ova tema je intenzivno istraživana 1980-ih i 1990-ih te su brojni rezultati uspješno demistificirali većinu poduzetničkih mitova. Usprkos tome, poduzetnički mitovi opstaju i redovito se pojavljuju na web portalima, u medijima i člancima blogera. S druge strane suvremeni udžbenici poduzetništva uključuju poduzetničke mitove kao lekciju koja može eliminirati neke prepreke za nove poduzetnike. Ovim istraživanjem utvrđeno je da su poduzetnički mitovi ponešto prisutni među mlađim, niže obrazovanim, ispitanicima ne-poduzetnicima u Hrvatskoj. Ipak, niti ove skupine ispitanika u prosjeku ne drže poduzetničke mitove, realnošću. Daljnja analiza je istaknula da postoji statistički značajna, ali slaba i negativna povezanost između percepcije poduzetničkih mitova kao mitova (ne kao realnosti) i više razine poduzentičkih namjera.

Nova generacija poduzetnika; generacija Z [Elektronička građa] / Vedrana Šimunić Rod. - Graf. prikazi.
Bibliografija: 25 jed. - Sažetak ; Summary. - Suvremeni način življenja, uvođenje tehnologije u sve sfere života, netolerantnost te želja za neovisnošću i uspjehom stvorili su novu generaciju poduzetnika, takozvanu Z generaciju. Generacija mladih ljudi koji dolaze na tržište rada s novim pogledom na svijet postaju sve zanimljiviji znanstvenicima, a njihova želja za ostvarenjem poduzetničkih ideja postaje glavna tema svih generacija ljudi. Z generacija, zbog svojih specifičnosti, moći stvaranja trenda te navika koje posjeduje postaje glavna tema ovog rada. Cilj rada je istražiti radi li se doista o novoj generaciji poduzetnika kroz karakteristike koje posjeduju pripadnici Z generacije te koliko tehnologija utječe na kreiranje njihove svijesti tj. buduće poslovne ideje. U radu će se primarnim i sekundarnim istraživanjem detaljnije pojasniti cilj rada kao i postavljene hipoteze. Sekundarnim istraživanjem autorica će utvrditi dolazi li doista s godinama do povećanja broja poduzetnika u Republici Hrvatskoj koji su pokazatelj povezanosti tehnologije i poduzetništva dok će fokus primarnog istraživanja biti na Z generaciji, njihovim navikama, idejama, prihvaćanju tehnologije kao suvremenom načinu življenja te na koji način mladi iskorištavaju tehnologiju i usmjeravaju je prema ostvarenju svojeg cilja. Na samom kraju rada utvrdit će se koliko su mladi stvarno zainteresirani za poduzetništvo i samozapošljavanje te ima li utjecaj rano poimanje poduzetništva na ostvarenje vlastitog poduzetničkog pothvata. - The modern way of life, the introduction of technology in every aspect of our lives, impatience, as well as the desire for independence and success, have created a new generation of entrepreneurs, the so-called Z generation. A new generation of young people entering the job market with a new worldview is becoming more interesting to scientists, and their desire to come up with entrepreneurial ideas is attracting the interest of all generations. The Z generation has become the main theme of this paper because of its characteristics, habits and the power to create trends. This paper aims to investigate whether this really is a new generation of entrepreneurs through the characteristics exhibited by its members, and how much technology influences the creation of their awareness, i.e. future business ideas. The primary and secondary research will explain in more detail the aim of the paper as well as the set hypotheses. The primary research will focus on the Z generation, their habits, ideas, the adoption of technology as a modern way of life and how the youth exploits technology in pursuit of their goal. The secondary research will determine whether there is indeed an increase in the number of entrepreneurs in the Republic of Croatia and whether it is an indicator of the connection between technology and entrepreneurship. The final part of the paper will determine young people’s level of interest in entrepreneurship and self-employment, and whether the early understanding of entrepreneurship has an impact on the realization of their entrepreneurial venture.

Organizational culture in logistics companies and its impact on employee satisfaction [Elektronička građa] / Mateja Čuček, Sonja Mlaker Kač. - Graf. prikazi.
Bibliografija: 36 jed. - Summary ; Sažetak. - The aim of this research was to analyze organizational culture and the impact of different types of organizational cultures on employee satisfaction in the Slovenian logistics sector. Logistics is a service-oriented sector and therefore the impact of employee satisfaction on the quality of logistics service is even more important than in general. For the purpose of research, we conducted a quantitative survey, which combined the OCAI survey for the determination of organizational culture and the survey of employee satisfaction. The research results showed that organizational culture in Slovenian logistics sector has an impact on employee satisfaction. We can also confirm that type of organizational culture influences the satisfaction of employees. The clan and hierarchical type of organizational culture are dominant in Slovenian logistics sector. Employees prefer the clan culture which, accordingly, also leads to more employee satisfaction. It can be argued that employees in Slovenian logistics sector are the most dissatisfied with the type of market culture. - Cilj ovog istraživanja je analizirati organizacijsku kulturu i utjecaj njenih različitih tipova na zadovoljstvo zaposlenika u slovenskom sektoru logistike. Logistički je sektor orijentiran na usluge, zbog čega je utjecaj zadovoljstva zaposlenika na kvalitetu logističke usluge još važnija, negoli je to u općim uvjetima. Za potrebe ovog istraživanja, provedena je anketa, zasnovana na instrumentu OCAI za utvrđivanje organizacijske kulture te anketi za utvrđivanje zadovoljstva zaposlenika. Rezultati istraživanja pokazuju da organizacijska kultura u slovenskom sektoru logistike utječe na zadovoljstvo zaposlenika. Također se može utvrditi tip kulture, koja utječe na zadovoljstvo, pri čemu u slovenskom logističkom sektoru prevladavaju tipovi klanske i hijerarhijske kulture. Zaposlenici preferiraju klansku kulturu, koja vodi prema najvišoj razini njihovog zadovoljstva. Može se argumentirati da su zaposlenici u slovenskom logističkom sektoru najnezadovoljniji tržišnim oblikom organizacijske kulture.

Pandemic crisis management [Elektronička građa] : threats and opportunities for humans and planet Earth / Nidžara Osmanagić Bedenik. - Graf. prikazi.
Bibliografija: 48 jed. - Summary. - The first recorded COVID-19 case emerged in China and, within a few months, it has spread to 210 countries globally, thrusting people into danger, uncertainty, fear, and of course physical and social isolation. The impacts of this pandemic are significant for every aspect of our lives. Crises include risk and chances at the same time. As Shakespeare said, “There is nothing either good or bad, but thinking makes it so“. This paper focuses on threats and opportunities of the pandemic crisis for humans and planet Earth. Crisis is defined as an unplanned and unwanted process of limited duration and impact, which endangers primary goals, and produces ambivalent outcome. Crisis management encompasses three phases: avoiding the crisis, identifying its symptoms when they occur and finding ways out of the crisis. There are several research questions related to that. First, could the COVID-19 crisis be avoided? Or at least could its onset be recognized early? Second, how can the pandemic crisis be measured in terms of its intensity and depth? Third, which ways lead us out of the crisis? And fourth, which lessons have to be learned? Exploring the novel literature and research findings provides new insights into the pandemic crisis and the crisis management process, which is the aim of the paper. With its results and major conclusions this paper provides a holistic perspective to the pandemic crisis and crisis management.

Project management education in Croatia [Elektronička građa] : a focus on the IT sector needs / Ivana Bestvina Bukvić, Iva Buljubašić, Marija Ivić. - Graf. prikazi.
Bibliografija: 69 jed. - Summary ; Sažetak. - Since today's dynamic and competitive business environment increasingly requires additional level of competence, the project manager is, certainly, a profession whose value and demand is growing. As to reach the project objective, the project manager should have an adequate education, which is the reason why the corporations, especially in the Information Technology (IT) industry, are among leaders in investment to project management education and certification. The aim of this paper is to contribute to the identification and understanding of the project management education model in Croatia and explore possibilities for its improvements, especially in the field of the project management in the IT industry. For that reason, through 2018 and 2019, authors conducted the research on availability of project management education programs in Croatia, opportunities for international certification as well as attitudes of the project management professionals in IT sector on the existing education model. The study suggests that there is a growing trend of project managers’ certification, especially in the IT industry, as well as a variety of informal programs for project management education. Simultaneously, there is a lack of project management university study programs. Empirical results show that project management study programs lack the practical segment and are, in most cases, offering only fundamental theoretical knowledge. Therefore, authors, on the basis of the literature review and analysis of IT sector needs assessment, provide recommendations of the domains, to be included into future university study programs. - Budući da današnje, dinamično i konkurentno poslovno okruženje, sve više zahtijeva dodatnu razinu kompetencija, projektni menadžer je, svakako, profesija čija vrijednost raste, kao i potražnja za njom. Za postizanje projektnog cilja, projektni menadžer treba imati odgovarajuću naobrazbu, zbog čega su korporacije, posebno u industriji informacijskih tehnologija (IT), među vodećim investitorima u obrazovanje i certificiranje svojih zaposlenika u području upravljanja projektima. Cilj ovog rada je pridonijeti identificiranju i razumijevanju modela obrazovanja iz područja projektnog menadžmenta u Hrvatskoj i istražiti mogućnosti za njegova poboljšanja,posebno u području upravljanja projektima u IT industriji. Zbog toga su autori, tijekom 2018. i 2019. godine, proveli istraživanje o dostupnosti obrazovnih programa za upravljanje projektima u Hrvatskoj, mogućnostima međunarodne certifikacije projektnih menadžera, kao i o stavovima profesionalaca u projektnom menadžmentu IT sektora o kvaliteti postojećeg obrazovnog modela. U okviru ovog istraživanja utvrđen je rastući trend broja certificiranih projektnih menadžera, posebno u IT industriji, kao i postojanje brojnih neformalnih programa za obrazovanje u upravljanju projektima, međutim, nedostaje sveučilišnih studijskih programa. Također, empirijski rezultati pokazuje da studijskim programima iz područja projektnog menadžmenta nedostaje praktični segment te da u većini slučajeva nude samo osnovna teorijska znanja. Stoga autori, na osnovu analize literature i procjene potreba IT industrije, predlažu područja, koja je potrebno uključiti u buduće sveučilišne studijske programe.

BERISHA Qehaja, Albana
Strategy tools in use [Elektronička građa] : new empirical insights from the strategy-as-practice perspective / Albana Berisha Qehaja, Enver Kutllovci. - Graf. prikazi.
Bibliografija: 85 jed. - Summary ; Sažetak. - This paper examines the usage of strategy tools from the strategy-as-practice perspective. In general, there is a lack of empirical evidence regarding the use of strategy tools, particularly in transition economies. The comprehensive and up-to-date research is mainly concerned with the extent of their use and classification. Thus, academics have already highlighted the need to review their role, importance, and use. Accordingly, this research seeks to bridge the current gap between theoretical constructs and empirical proof of the use of strategy tools in enterprises. The study design used for this research is cross-sectional and data were obtained from 314 enterprises in the Republic of Kosova, using standardized survey-based questionnaires. The purpose of this study is to assess the extent to which strategy tools are used in Kosovan enterprises. It also aims to distinguish their use according to educational background of managers/owners, enterprise size and across different sectors. The results of this study reveal that Kosovan enterprises have a low usage rate of strategy tools. More precisely, the two most used strategy tools are SWOT analysis and vision and mission statements. This paper provides some important insights into strategy tools usage in the Republic of Kosova, as a transition economy. While it provides a better understanding and awareness of strategy tools usage, there are other possible study areas that could offer significant value in future research. - U ovom se radu istražuje uporaba alata strateškog menadžmenta iz perspektive strategije kao prakse. U načelu, postoji manjak empirijskih dokaza o korištenju alata strateškog menadžmenta, posebno u tranzicijskim gospodarstvima. Sveobuhvatna i recentna istraživanja uglavnom se bave opsegom njihove uporabe te klasifikacijom. Dakle, već je iskazana potreba za procjenom uloge, značaja i uporabe ovih alata. U skladu s time, u ovom se istraživanju pokušava premostiti trenutno postojeći jaz između teorijskih konstrukata i praktične uporabe alata strateškog menadžmenta u poduzećima. Za ovo je istraživanje korišteni kros-sekcijski istraživački nacrt, a podaci su dobiveni od 314 poduzeća iz Republike Kosovo, koristeći standardizirane upitnike. U ovoj se studiji želi procijeniti razina do koje se alati strateškog menadžmenta koriste u poduzećima na Kosovu, kao i kakve su razlike u njihovom korištenju, s obzirom na obrazovanje menadžera, odnosno vlasnika poduzeća, njegovu veličinu te pripadnost sektoru (proizvodnom, trgovinskom, uslužnom). Rezultati istraživanja govore da poduzeća na Kosovu u maloj mjeri koriste alate strateškog menadžmenta. Preciznije rečeno, dva najčešće korištena alata su SWOT analiza te iskazi vizije i misije. U ovom se radu pružaju značajni uvidi u korištenje alata strateškog menadžmenta na Kosovu, kao tranzicijskom gospodarstvu. Iako se radom pruža bolje razumijevanje alata strateškog menadžmenta, postoje i dodatne mogućnosti istraživanja, koje bi u budućnosti pružile značajnu vrijednost.

NIŽETIĆ, Dean, specijalist informatičkog menadžmenta
Usage of information systems for knowledge management in small tourist agencies [Elektronička građa] / Dean Nižetić, Anton Florijan Barišić. - Graf. prikazi.
Bibliografija: 31 jed. - Summary ; Sažetak. - Rapid development of technologies led to emergence of new opportunities for businesses such as effective management of knowledge resources for achieving organizational performance. The purpose of this paper was to determine whether the agencies are using KM systems available on the market, what are the reasons for their adoption, and explore the adequacy of implemented systems, and to define the characteristics of “ideal” KM systems for small organizations. In that sense, the main goal of the research was to explore the adoption degree of information technology for knowledge management in small tourist agencies with fewer than 20 employees. Based on survey among small tourist agencies conducted upon the sample of 68 usable responses from on-line questionnaire, this research outlines position and development trends in using information systems for knowledge management answering following questions: (a) Do agencies recognize the benefits of using knowledge management systems and in which segments of their business?: (b) What types of knowledge management systems they use and in which business segments?: (c) What are the reasons that agencies may not use knowledge management systems? In the research, the mathematical-statistical methods have been used, in order to analyse the attitude of the small Croatian tourist businesses toward usage of modern technologies to bust their business performances. The results also have indicated the reasons for low adoption of IT KM solutions in their everyday business operations. Based on the conducted analysis, a framework specification of an “ideal” KM system has been suggested. - Brz razvoj tehnologija doveo je do pojave novih prilika za organizacije kao što je djelotvorno upravljanje resursima znanja za postizanje organizacijske uspješnosti. Svrha ovog rada bila je utvrditi koriste li agencije sustave UZ dostupne na tržištu, koji su razlozi za njihovo usvajanje, te istražiti adekvatnost implementiranih sustava i definirati karakteristike „idealnih“sustava UZ za male organizacije , U tom je smislu glavni cilj istraživanja bio istražiti razinu usvojenosti informacijske tehnologije za upravljanje znanjem u malim turističkim agencijama s manje od 10 zaposlenih. Na temelju ankete provedene među malim turističkim agencijama na uzorku od 68 valjanih odgovora iz on-line upitnika, ovo istraživanje ocrtava položaj i trendove razvoja uporabe informacijskih sustava za upravljanje znanjem odgovarajući na sljedeća pitanja: (a) prepoznaju li agencije koristi od korištenja sustave upravljanja znanjem i u kojim segmentima svog poslovanja, (b) koje vrste sustava upravljanja znanjem koriste i u kojim poslovnim segmentima, (c) koji su razlozi da se sustavi upravljanja znanjem ne koriste? U istraživanju su korištene matematičko-statističke metode za analizu odnosa malog hrvatskog turističkog poduzeća prema korištenju suvremenih tehnologija radi poboljšanja njihovih poslovnih rezultata. Rezultati su ukazali i na razloge slabog usvajanja IT UZ rješenja u svakodnevnom poslovanju. Na temelju provedene analize predložena je okvirna specifikacija „idealnog“sustava UZ.

Bibliografska bilješka uz tekst ; bibliografija: 17 jed. - Sažetak ; Summary. - Znanstveni časopisi predstavljaju ključan medij za znanstveno komuniciranje, a za knjižničare izvor za analizu znanstvene produktivnost. Cilj je rada analizirati hrvatske znanstvene i stručne časopise iz polja ekonomije pomoću kvantitativnog pomagala Journal Citation Report (JCR) baze Web of Science i metrijskog pokazatelja SCImago Journal Rank (SJR) o časopisima u Scopusu. Svrha je rada omogućiti znanstvenicima iz ekonomije pregled zastupljenosti hrvatskih ekonomskih časopisa u relevantnim bazama. Uzorak obuhvaća 69 aktivnih časopisa iz ekonomije na Portalu hrvatskih znanstvenih i stručnih časopisa – Hrčak. Metodologija rada analiza je časopisa na Hrčku kako bi se saznalo koji su časopisi indeksirani u citatnim bazama Web of Science i Scopus, a zatim analiza prema parametrima: najbolje rangirani časopis prema čimbeniku odjeka u JCR i prema SJR indikatoru, najcitiraniji članak te najproduktivniji autori. Ovim istraživanjem dobio se uvid u hrvatske časopise indeksirane u bazama kategorije a1 prema Pravilniku o uvjetima za izbor u znanstvena zvanja te uvid u znanstvenu produktivnost znanstvenika unutar polja ekonomije. - Scientific journals are a key medium for scientific communication, and for librarians a main source for analyzing scientific productivity. The aim of this paper is to analyze Croatian scientific and professional journals in the field of economics using the quantitative tool Journal Citation Report (JCR) of the Web of Science database and the metric indicator SCImago Journal Rank (SJR) on journals in Scopus. The purpose of this paper is to enable economy scientists to present the overview of Croatian economic journals in relevant databases. The sample includes 69 active journals in economics on the Portal of Croatian scientific and professional journals - Hrčak. The used method is the analysis of journals on Hrčak to find out which journals are indexed in Web of Science and Scopus citation databases, together with the analysis by following parameters: best ranked journal by impact factor in JCR and SJR indicator, the most cited article and most productive authors. This research provided insight into Croatian journals indexed in databases of category a1 according to the Rule book on Conditions for Selection in Scientific Professions as well as it gave insight into the scientific productivity of scientists within the field of economics.

Copyright violation of predators in scientific publishing - Biochemia Medica's harmful experience and proposed solution [Elektronička građa] / Daria Pašalić, Vesna Šupak Smolčić. - Ilustr., graf. prikazi.
Bibliografija: 6 jed. - Summary. - Biochemia Medica is an open access journal that does not charge manuscript processing or publishing. All editorial staff are continuously educated and directed to follow the highest ethical and scholarly publishing standards in all steps of the manuscript processing. They are all laboratory medicine professionals, who apart from their regular jobs, are in charge of different phases in Journal processing as volunteers. The publisher of the Journal is scientific and professional association of laboratory medicine professionals, Croatian Society of Medical Biochemistry and Laboratory medicine (CSMBLM).During November and December 2018, without knowledge of the editorial staff, unknown perpetrator(s) downloaded a respectable number of articles published in Biochemia Medica as PDF and launched an illegal web page under the same journal name with downloaded articles. Although this was a very harmful experience, we have learned a lot from it and we would like to share this with scientific journals’ community. Therefore, we would like to share this harmful experience, and to present a short workflow on how to manage situations like this if it will be necessary for any scientific journal in the future.

Accuracy in online media [Elektronička građa] : insufficient journalistic routines in fact-checking and corrections / Mato Brautović, Sandra Buratović Maštrapa, Romana John. - Graf. prikazi.
Bibliografija: str. 83-85. - Summary ; Sažetak. - Accuracy is at the core of what journalists do and it amounts to journalistic commitment to report without errors. This tenet of journalism is now in danger, because of the influence of digitalization, changes in media landscapes, and the utilization of the assertation model of journalism. In this study, we used a combination of content analysis and visual network analysis to investigate how subjective errors are disseminated through an online environment, how time/speed influences the propagation of errors, and what the error correction procedures/routines are. The results demonstrate that 69% of the analyzed stories contained errors, and the main cause of such errors was the use of secondary sources, instead of primary ones, these errors transcend national borders and, time/speed had only a minor role in the emergence and correction of the errors, etc. Out of the 107 media websites analyzed, only seventeen provide certain modalities of requesting error correction. - Točnost je osnova novinarskog posla i predstavlja novinarsku posvećenost izvještavanju bez grešaka. To načelo novinarstva sada je u dodatnoj opasnosti zbog utjecaja digitalizacije, promjena u medijskom okruženju i primjene novih modela novinarstva utemeljenog na mišljenjima. U ovom istraživanju korištena je kombinacija analize sadržaja i vizualne analize mreže kako bi se istražilo na koji se način subjektivne pogreške šire putem internetskog okruženja, kako vrijeme/brzina utječe na širenje pogrešaka i kakvi su postupci, odnosno rutine ispravljanja pogrešaka. Rezultati pokazuju da je 69 % analiziranih napisa imalo pogreške, da je glavni uzrok takvih pogrešaka upotreba sekundarnih umjesto primarnih izvora te da pogreške prelaze državne granice, a vrijeme/brzina nema bitnu ulogu u nastanku i ispravljanju grešaka. Od 107 analiziranih medijskih mrežnih stranica, samo ih 17 pruža mogućnost podnošenja zahtjeva za ispravku pogreške.

GRADEČAK, Kristijan
Schellingovo samorazumijevanje u povijesti filozofije [Elektronička građa] / Kristijan Gradečak.
Tema broja: Schellingova filozofija - izabrani problemi. - Bibliografske bilješke uz tekst. - Sažetak ; Zusammenfassung. - Schelling svoj položaj u povijesti filozofije shvaća dvostruko: u ranijem razdoblju svog stvaralaštva doprinosio je razvoju negativne filozofije, tj. filozofije apsolutnog identiteta, u svrhu njenog dovršenja i preobrazbe u pozitivnu filozofiju. No usporedno je utemeljivao i razvijao povijesnu filozofiju kao filozofiju objave koja je bila zbiljski sadržaj pozitivne filozofije. Stav o ograničenosti racionalne filozofije može se potvrditi u cjelokupnom Schellingovu djelu, neovisno o razdoblju nastajanja pojedinačnih spisa. Zbog toga je opravdano potvrđivati i u ranijem razdoblju njegova stvaralaštva barem metodičku pripremu za pozitivnu filozofiju. Tako Schelling svoju ulogu u povijesti filozofije vidi u konačnom razrješenju paralelizma između neprevladane negativne i nerealizirane pozitivne filozofije. - Schelling begreift seine eigene Stellung in der Philosophiegeschichte auf zweifache Weise: mit seinem Frühwerk hat er zu der Entwicklung der negativen Philosophie oder der Philosophie der absoluten Identität beigetragen, so dass sie vollends ihre Verwandlung in die positive Philosophie vollziehen könnte. Parallel dazu hat er an die Begründung und Entwicklung der geschichtlichen bzw. Philosophie der Offenbarung gearbeitet. Letztere ist auch wirklicher Inhalt der positiven Philosophie. Diese Auffassung über die Begrenztheit der rationalen Philosophie kann man im gesammten Schellingschen Werk bestätigen, unabhänging von der Entstehungszeit einzelner Schriften. Deshalb ist man durchaus berechtigt auch in dem früheren Werk zumindest die methodische Vorbereitung zur positiven Philosophie zu betrachten. Demzufolge sieht Schelling seine eigene Rolle in der Philosophiegeschiche als eine vermittelnde und endlich den Parallelismus zwischen der unüberwältigten negativen und unrealisierten positiven Philosophie auflösende.

Stvaralaštvo kao technê [Elektronička građa] : središnji problem filozofije suvremenog doba / Marica Rajković.
Bibliografske bilješke uz tekst ; bibliografija: str. 29-30. - Sažetak ; Summary. - Filozofija 21. stoljeća dužna je preispitati fundamentalne pojmove na kojima je zasnovana kako bi se utvrdilo je li povijesni tijek utjecao na promjenu u njihovoj biti i utjecaju. Jedan od takvih pojmova je pojam stvaralaštva koji se od još od starogrčke epohe vezuje za poietičku filozofiju. Neophodno je postaviti pitanje o tome je li još uvijek opravdana podjela prema kojoj je stvaralaštvo sfera ποίησις ili se stvaranje sâmo u tolikoj mjeri promijenilo kroz povijesna kretanja da je potrebno iz temelja ponovno odrediti ne samo njegov pojam nego i sfere njegova utjecaja. Kroz proces takvog ispitivanja važno je ukazati na autore koji su (na različite načine) smatrali da upravo ono stvaralačko fundira pojam čovjeka, kao i na one autore koji su upozoravali na takvu mogućnost. Razlika između starogrčkog τέχνη i suvremene tehnike, razlika između čovjeka kao zoon politikon i zoon technikon te razlika u određenjima pojma stvaranja otvaraju bitno pitanje: je li problem stvaralaštva toliko temeljan da je zbog njega neophodno preispitati filozofiju jedne epohe u cjelini?. - Twenty-first century philosophy is required to re-examine the fundamental concepts upon which it is founded in order to affirm whether the course of history has caused changes in its essence and influence. One such concept is the concept of creativity, which has been tied to poietic philosophy since Ancient Greece. It is necessary to examine the validity of the division according to which creativity lies within the sphere of ποίησις, or if creativity itself has changed to such an extent throughout history that both its concept and its sphere of influence must be thoroughly re-defined. Through such inquiry, it is important to note authors who have (in various ways) claimed that the act of creativity lies at the basis of the concept of man, as well as authors who have indicated this as a possibility. The difference between the Old Greek τέχνη and the modern ‘technique’, the difference between man as a zoon politikon and zoon technikon, and differences in definitions of the concept of creativity all raise an important question: is the problem of creativity so fundamental that it requires a complete re examination of the philosophy of an entire era?.

PAIĆ, Žarko
Film kao mišljenje [Elektronička građa] : Deleuzeova "ontologija slika" / Žarko Paić.
Tema broja: Filozofija pokretnih slika (I.). - Bibliografske bilješke uz tekst. - Sažetak ; Abstract. - U studijama o filmu pokazuje se prekretnim to što Deleuze sintetički povezuje rasklopljenu »bit« metafizike kao ontologije (bitak – bog – svijet – čovjek) s novim pristupom ne samo kretanju pojma, govoreći hegelovski, nego i mišljenju kao događaju. Isto još više vrijedi za razumijevanje onoga što traje u vremenu i stoga ima karakter misaone slike. Kako autor pokazuje u članku, Deleuze nju uspostavlja tako što mozak postaje ekran, a film iz sfere tzv. realiteta postaje virtualni kôd svijeta kao slike. Između koncepta i slike dokida se razlika kada slika više ne prethodi pojmu i kada pojam više ne prethodi slici. Koliko je ovaj obrat presudan za Deleuzeovo shvaćanje filma može se uočiti u izvedbi pojma događaja (événement). Slika i pojam odgovaraju singularnosti događaja. Problem s razumijevanjem Deleuzeove »ontologije slika« pokazuje da film ne možemo svesti na autonomnu proizvodnju kinematičkoga načina mišljenja ako prethodno ne razjasnimo što je to uopće pokret i kako nastaje slika. Film je u tom paradigmatskome slučaju ne samo »vizualni kôd« suvremene umjetnosti. Njegova se »bit« razotkriva u tome što omogućuje da slika-pokret i slika-vrijeme sintetički realiziraju mogućnosti tehnosfere kao: (1) računanja, (2) planiranja i (3) konstrukcije. Naposljetku, filmsko mišljenje koje Deleuze zagovara postaje pitanje o mogućnostima da film kao metafilm dosegne novu razinu filozofijskoga razmatranja onoga što postaje i nastaje novim sklopom odnosa između bitka i događaja. - In Deleuzeʼs studies on film, it is striking that the dismantled “essence” of metaphysics as an ontology (being – god – world – man) is synthetically linked with a new approach not only to the movement of the concept, speaking in Hegelʼs language but also to the thinking as an event. That is even more true for the understanding of that which lasts in time and thus has the character of the thought-image. As the author points out in this article, Deleuze establishes this by turning the brain into a screen, and the film from the sphere of the so-called reality becomes the virtual code of the world as an image. The difference between concept and image eliminates the difference between the image no longer preceding the term and the term no longer preceding the image. How crucial this turn will be to Deleuzeʼs notion of the cinema can be seen in the derivation of the concept of an event (événement). The image and term correspond to the singularity of the event. The problem with comprehending Deleuzeʼs “images-ontology” shows that film cannot be reduced to the autonomous production of a cinematic way of thinking unless we have previously clarified what movement is and how it is created. In this paradigmatic case, a cinema cannot be viewed simply as a “visual code” of contemporary art. Its “essence” is revealed in that it enables the image-movement and image-time to synthetically realize the possibilities of the technosphere as (1) computation, (2) planning and (3) construction. Eventually, the cinematic thinking advocated by Deleuze becomes a question of the possibility of film as a meta-film reaching a new level of philosophical consideration of what becomes and emerges with a new set of relations between Being and event.

SMILJANIĆ, Ivan, filozof
Filozofija kao duhovna znanost u Schellingovu srednjem razdoblju [Elektronička građa] / Ivan Smiljanić.
Tema broja: Schellingova filozofija - izabrani problemi. - Bibliografske bilješke uz tekst. - Sažetak ; Zusammenfassung. - U ovom radu prikazuje se razvoj nužne ideje sistema, koji je istinska forma filozofije kao znanosti, onako kako je to izvedeno u srednjem razdoblju Schellingove misli, osobito u okviru njegovih Erlangenskih predavanja iz 1821. godine. Schelling prikazuje kako apsolutni subjekt, krećući se od jednoga obličja znanja prema drugomu, gradi totalni sistem uzdignut ponad svih partikularnih sistema i tako stječe samospoznaju koja je pravi sadržaj filozofije kao znanosti. Istinsko filozofijsko znanje opire se kretanju apsolutnoga subjekta, čime se čovječja svijest kao princip partikularne svijesti izgrađuje kao svijest apsolutnog subjekta koji je princip univerzalne svijesti. Samo filozofija kao znanost može čovjeka voditi i dovesti do najvišega znanja o svijesti apsolutnoga subjekta kao njegove vlastite svijesti. - In dieser Arbeit wird vorgestellt die Entwicklung einer notwendigen Idee des Systems, die die wahre Form der Philosophie als Wissenschaft darstellt, wie es in Schellings späterem Denken, besonders während seiner Erlangen Vorlesungen von 1821 ausgeführt wurde. Schelling zeigt, dass das absolute Subjekt, das sich von einer Wissensform zur anderen bewegt, das über alle bestimmten Systeme erhobene Totalsystem bildet, und dadurch die Selbsterkenntnis erlangt, welche der wahre Inhalt der Philosophie als Wissenschaft ist. Das wahre philosophische Wissen ist das, was sich der Bewegung des absoluten Subjekts widersetzt, wodurch das menschliche Bewusstsein als das Bewusstsein des absoluten Subjekts ausgebildet wird. Nur die Philosophie als Wissenschaft kann den Menschen zur höchsten Wissen über das Bewusstsein des absoluten Subjekts als sein eigenes Bewusstsein führen und bringen.

Tema broja: Schellingova filozofija - izabrani problemi. - Bibliografske bilješke uz tekst. - Sažetak ; Zusammenfassung. - U članku se nastoji istražiti i što preciznije odrediti višestruko složeni odnos Heideggerova mišljenja spram Schellingove filozofije. Od početne fascinacije Schellingovim središnjim spisom o slobodi, u kojem nalazi značajne analogije s vlastitim pokušajima promišljanja konačnosti slobode, a time i samog bitka, Heidegger će se u daljnjem razvijanju vlastita mišljenja od Schellinga sve više i sve oštrije distancirati, prigovarajući mu da ne uspijeva prevladati metafiziku, već ostaje u njezinu vidokrugu, premda na izniman i u svakom pogledu respektabilan način. Primjerenost te prosudbe u članku se stavlja u pitanje i svestrano propituje kritičkom usporedbom i temeljitom pojmovnom analizom Schellingova shvaćanja volje, indiferencije, ljubavi i ekstaze s jedne, te Heideggerova shvaćanja zla, volje za voljom, bezdana i opuštenosti s druge strane. Pritom na vidjelo zaključno izlazi stvarna srodnost tih središnjih pojmova kasne filozofije jednog i drugog mislioca, koja je mnogo veća nego što je to Heidegger bio spreman uvidjeti i iskoristiti za krajnje svrhe vlastita mišljenja. - Der Artikel versucht, die vielfältige und komplexe Beziehung von Heideggers Denken zu Schellings Philosophie zu untersuchen und so genau wie möglich zu bestimmen. Von der anfänglichen Faszination für Schellings zentrale Schrift über die Freiheit, in der er bedeutende Analogien zu seinen eigenen Versuchen findet, die Endlichkeit der Freiheit und damit des Seins selbst nachzuweisen, wird sich Heidegger im weiteren Entwicklung seines Denkens von Schelling immer mehr und immer schärfer distanzieren, indem er ihm vorwirft, die Metaphysik nicht zu überwinden, sondern innerhalb ihres Horizontes zu bleiben, wenn auch auf eine bemerkenswerte und in jeder Hinsicht respektable Weise. Die Angemessenheit dieses Urteils wird im Artikel durch einen kritischen Vergleich und eingehende Begriffsanalyse von Schellings Konzeption von Willen, Liebe, Ekstase und Indifferenz einerseits und Heideggers Auffassung von Bösem, Willen zum Willen, Kehre und Gelassenheit andererseits in Frage gestellt und allseitig überprüft. Als Ergebnis der Untersuchung kommt die sachliche Verwandtschaft dieser zentralen Konzepte der Spätphilosophie des einen und des anderen Denkers ans Licht, die viel größer ist als Heidegger bereit war, es zu sehen, zu akzeptieren und für die letzten Zwecke des eigenen Denkens zu verwenden.

SINGBO, Odilon-Gbènoukpo
Postsmrtno stanje [Elektronička građa] : metafizičko-eshatološke ambicije transhumanizma / Odilon-Gbènoukpo Singbo.
Tema broja: Ljudska priroda. - Bibliografske bilješke uz tekst. - Sažetak ; Abstract. - U radu se ispituju metafizičke i eshatološke implikacije transhumanizma, osobito u svjetlu njegove ideje o besmrtnosti ljudske vrste. Kroz jezgrovit prikaz povijesnog okvira pojave transhumanističkog pokreta, rad ističe njegove glavne karakteristike kao što su poboljšanje čovjeka, nadilaženje ljudskoga i pobjeda inherentnih čovjekovih nedostataka pomoću suvremenih grana znanosti te suvremene tehnike. Navedene karakteristike pomažu u shvaćanju metafizike i eshatologije na način kako ih formiraju neki aspekti transhumanizma. Upravo su ti aspekti po svojim načelima nedvojbeno tehničke i sekularne naravi jer se odmiču od religioznog shvaćanja ljudskih čežnji i smrti. Često se smrt shvaća kao greška, a proces starenja kao patološko, ponižavajuće, ali izlječivo stanje. Transhumanizam na taj način označava kraj humanističko-transcendentalne perspektive o slobodnom subjektu stvorenom dobrotom i spašenom ljubavlju Boga u otajstvu Isusa Krista. Kroz rad se argumentira da tehnokratska rješenja ne mogu ispuniti temeljne ljudske čežnje. - The paper analyses various metaphysical and eschatological implications of transhumanism, especially in the light of its idea of the immortality of the human species. Through a concise interpretation of the historical framework of the emergence of the transhumanist movement, the paper highlights its main features such as human improvement, overcoming human nature, and overcoming inherent human deficiencies using modern scientific disciplines and modern technologies. Those features help understand metaphysics and eschatology as formed by some aspects of transhumanism. These aspects are unquestionably technological and secular in their principles, as they distance themselves from the religious understanding of human longing and death. Often, death is understood as a mistake, while the process of ageing is seen as a pathological, humiliating but curable condition. Transhumanism thus marks the end of the humantranscendental perspective of a free individual, created by the goodness of God and saved by the love of God, through the mystery of Jesus Christ. The paper argues that technocratic solutions cannot fulfil fundamental human longings.

BAKSA, Goran
Povijesno-filozofijski horizont i oblikovanje pojma prirode u Schellingovu Spisu o slobodi [Elektronička građa] / Goran Baksa.
Tema broja: Schellingova filozofija - izabrani problemi. - Bibliografske bilješke uz tekst. - Sažetak ; Abstract. - Spis o slobodi predstavlja prekretnicu u Schellingovoj filozofiji. Već je filozofijom prirode Schelling napravio otklon od strogih idealističkih okvira, prvenstveno Kanta i Fichtea, jer je za sistematsko utemeljenje cjelokupnog znanja nužan identitet subjekta i objekta tražio u samome objektu kao momentu djelatnosti samopostavljanja apsolutnog subjekta, no tek je sa Spisom o slobodi istupio iz tog okvira. Riječ je o uvođenju drugog principa, koji je komplementaran, ali nesvodiv na standardni idealistički princip samosvijesti. Radi se o temelju ili prirodi u Bogu. Tek se kroz to dvojstvo principa mogao zahvatiti pozitivan pojam slobode kao mogućnosti za dobro i zlo. Tako cjelovito pojmljena činjenica ljudske slobode povezala se s cjelinom bića. Svrha takvog objašnjenja bio je pokušaj odgovora na problem koji se protezao kroz cijelo Schellingovo filozofiranje – odnos konačnog i beskonačnog. - The Essay on Freedom represents a milestone in the philosophy of F. W. J. Schelling. Although Schelling already deviated from a strictly idealistic framework with his philosophy of nature, notably from that of Kant and Fichte, because he was seeking a moment of self-positing activity of the absolute subject in the object itself, it was only with The Essay on Freedom that he stepped out of that framework. The central point considered is an introduction of the second principle that was complementary, but irreducible to the standard idealist principle of self consciousness. It was about the ground or nature in God. Only through that duality of principles, it was possible to grasp the positive notion of freedom as the possibility for good and evil. In such manner comprehended, the fact of human freedom in its entirety became relation with the whole of beings. The purpose of such explanation was an attempt to solve the problem that was spanning through Schellingʼs entire philosophy – the problem of the relation between finite and infinite.

PELC, Adrian
Probiti spektakl [Elektronička građa] : o nekim paradoksima filmske slike / Adrian Pelc.
Tema broja: Filozofija pokretnih slika (I.). - Bibliografija: str. 474-475. - Sažetak ; Abstract. - Ovaj rad pokušava suočiti dvije radikalne struje promišljanja filmske slike. U prvom se koraku definira kako je unutar određenih marksističkih teorija (Jonathan Beller, Guy Debord, Jean Baudrillard) filmska slika na osnovi svog tehničkog podrijetla, ali i efekata koje proizvodi, određena kao fenomen ontološki utemeljen u otuđenju i destrukciji neposredne prisutnosti. U drugom se koraku demonstrira kako je André Bazin, potaknut fenomenologijom i polazeći od gotovo identičnih premisa kao i marksisti, uspostavio dijametralno suprotne zaključke: tek se na filmu uistinu razotkriva stvarno. Oslanjajući se na rad Jacquesa Rancièrea, Jean-Luca Nancyja i Giorgia Agambena, u trećem koraku nastojim izvesti svojevrsnu sintezu među navedenim pozicijama i ispitati kako spektakl ostaje sačuvan, ali i prevrednovan unutar režima filmskih slika. Oko tog prevrednovanja počinju se nazirati konture zahtjevnog estetičkog programa koji se donekle podudara s, ali i odudara od ustaljenih interpretacija filmskog postmodernizma. - In this paper, confronted are two radical currents of thought about the film image. In a first step, demonstrated is how some Marxist theorists (Beller, Debord, Baudrillard) define the film image as ontologically grounded in alienation and the destruction of non-mediated presence due to its technical origin, as well as its effects. In a second step, I try to show how André Bazin, influenced by phenomenology and taking up identical premises as the Marxists, came to diametrically opposite conclusions: it isn’t but the film image that discloses the real. Drawing on the work of Jacques Rancière, Jean-Luc Nancy and Giorgio Agamben, in a third step I establish a certain synthesis between these two currents and examine how spectacle is guarded, but also re-evaluated within the regime of film images. Through this re-evaluation, one gets a glimpse at the contours of an exigent aesthetic program that in some respects conforms to, while also deviating from eminent ideas on cinematic postmodernism.

Sveobuhvatnost i razložnost koncepcija dobra u raspravi političkog liberalizma i perfekcionizma [Elektronička građa] / Michal Sládeček.
Tema broja: Ljudska priroda. - Bibliografske bilješke uz tekst ; bibliografija: str. 281-282. - Sažetak ; Abstract. - U članku se tvrdi da John Rawls u svojoj kritici perfekcionizma sa stajališta liberalističke neutralnosti razmatra koncepcije dobra bez demarkacije između njih, odnosno bez njihova razlikovanja. Naime, Rawls ne razrješava pitanje o tome je li tu riječ o sveobuhvatnoj religijskoj odnosno filozofsko-etičkoj koncepciji ili je riječ o parcijalnom poimanju lokalnih vrijednosti, dobara i ciljeva. Bez obzira na spornu upotrebu pojma sveobuhvatnosti, neophodno je zadržati koncept razložnosti jer poimanja dobra, da bi bila relevantna u političkoj raspravi, trebaju biti relativno dobro zasnovana, konzistentna i koherentna. Kada se pođe od danih razlikovanja, može se tvrditi da u pojedinim slučajevima uvođenje razmatranja određenih dobara u rasprave o osnovnim principima političkog ustrojstva može biti dobro potkrepljeno i, sa stajališta razložnog pluralizma, moralno opravdano. Ipak, umjereni liberalistički perfekcionizam treba precizirati odnose li se političke odluke na stvaranje opcija, na promociju vrijednih ili na odvraćanje od bezvrijednih dobara i u skladu s tim treba odrediti doseg perfekcionističkih mjera. - The paper argues that Rawls’ critique of perfectionism from the standpoint of neutral liberalism scrutinizes the conceptions of the good without demarcation between them, that is, without distinguishing whether they are comprehensive religious or philosophical conceptions, or whether they are piecemeal comprehensions of local values, concepts and goods. In addition to the high contestability in the use of the concept of comprehensiveness, it is necessary to retain the concept of reasonableness, as comprehensions of the good have to be to some extent well-founded, consistent and coherent to be considered relevant in a political dispute. Considering these distinctions, it can be claimed that, in particular cases, the application of considerations of the good in disputes concerning constitutional essentials can be supported and, considering reasonable pluralism, morally justified. Nevertheless, moderate perfectionism has to specify whether political decisions create and support options, promote valuable goods or they discourage worthless goods. It is necessary to delineate the limits of perfectionistic measures accordingly.

ŠEGEDIN, Petar, filozof
Uz pojam "začinjanja-rađanja" u prvoj verziji Razdoblja svijeta [Elektronička građa] / Petar Šegedin.
Tema broja: Schellingova filozofija - izabrani problemi. - Međunarodni skup Der Anfang der Weltalter (1811), Dubrovnik, 1.-5.10.2018. - Bibliografske bilješke uz tekst. - Sažetak ; Zusammenfassung. - U radu se tematizira Schellingov pojam »začinjanja-rađanja« (Zeugung) u prvoj verziji Razdoblja svijeta. Osnovu Schellingovih promišljanja u više verzija tog nedovršenog spisa čini pokušaj da se pojam vremena liši mehanicističke predodžbe ulančanog slijeda i da se vrijeme tematizira u točki razlikovanja – »rađanja« – prošlosti, sadašnjosti i budućnosti. U tom smislu postanak vremena tumači se u širem kontekstu razvijanja »prabića«, tj. njegove sebe-objave u živoj zbilji na način diferenciranja potencijalne i nezbiljske indiferencije subjekta i objekta. To diferenciranje svoju ključnu točku ima u tomu da se dotična indiferencija rastavlja od same sebe te se prevladava i za sobom ostavlja kao objektivni temelj vlastite žive subjektnosti. Riječ je o prirodi koja je za ono subjektivno njegov uvijek već prošli bitak. - In diesem Aufsatz wird Schellings Begriff der Zeugung in der ersten Fassung seines Werkes Die Weltalter thematisiert. Mehrere Fassungen dieser unvollendeten Schrift lassen die Grundlage von den Schellings Überlegungen im Versuch erkennen, den Zeitbegriff von der mechanistischen Konzeption der verketteten Aufeinanderfolge zu befreien und die Zeit im Punkt des Unterschieds – der „Zeugung“ – zwischen der Vergangenheit, der Gegenwart und der Zukunft zu erfassen. In diesem Sinne wird der Ursprung der Zeit im breiteren Kontext der Entwicklung eines „Urwesens“, d.h. seiner Selbstoffenbarung in der lebendigen Wirklichkeit interpretiert. Diese Selbstoffenbarung wird von Schelling als eine Differenzierung der ursprünglich potentiellen und unwirklichen Indifferenz von Subjekt und Objekt aufgefasst. Der entscheidende Punkt dieser Differenzierung liegt aber darin, dass die Indifferenz sich selbst von sich selbst scheidet und als der objektive Grund der eigenen lebendigen Subjektivität berwunden und hinter sich selbst zurückgelassen wird. Dieser Grund ist die Natur im Ganzen, die für das Subjektive sein immer schon vergangenes Sein darstellt.

Kultura kod ne-ljudskih životinja i evolucijsko podrijetlo ljudske kulture [Elektronička građa] / Marko Škorić, Aleksej Kišjuhas.
Tema broja: Ljudska priroda. - Bibliografija: str. 354-360. - Sažetak ; Abstract. - U radu se dovodi u pitanje zamisao o ontološkoj privilegiranosti ljudske vrste, za što smatramo da počiva na brojnim pogrešnim idejama. Jedna je od takvih pogrešnih ideja da je Homo sapiens jedina vrsta koja posjeduje kulturu. Najprije se ističe problematika (definiranja) kulture u kontekstu tzv. minimalističkih i ekspanzionističkih definicija toga fenomena, a zatim se navode primjeri kulturnog ponašanja kod ne ljudskih životinja. Kritički su analizirane i najčešće komponente za koje se obično smatra da su neophodne da bi se moglo govoriti o istinskoj kulturi, kao što su: društveno učenje, jezik, simboli, teorija uma, povijest, tradicija, prirodna pedagogija i kumulativnost kulture. Naposljetku, istaknute su implikacije jedne adekvatnije, ekspanzionističke i naturalističke, definicije kulture koja je utemeljena na evolucijskim (darvinističkim) osnovama. - This paper calls into question the ontological privilege of the human species that rests on many misguided ideas. One of these ideas is that Homo sapiens is the only species that possess culture. In this sense, the problem of (defining) culture is emphasised in the context of the so called minimalist and expansionist definitions. Furthermore, this paper details examples of cultural behaviour in non-human animals. The components commonly considered necessary to speak of true culture are also critically analysed. These components are social learning, language, symbols, the theory of mind, history, tradition, natural pedagogy, and the cumulativeness of culture. Finally, this paper brings attention to the implications of a more adequate, expansionist and naturalistic, definition of culture based on evolutionary (Darwinian) grounds.

Transhumanizam - filozofska osnova [Elektronička građa] / Lovro Furjanić.
Tema broja: Ljudska priroda. - Bibliografske bilješke uz tekst ; bibliografija: str. 246-248. - Sažetak ; Abstract. - Članak donosi pregled najosnovnijih postavki transhumanističkog pokreta. Transhumanistički pokret počinje krajem 20. stoljeća i zalaže se za korištenje tehnologije u svrhu unapređivanja ljudskog stanja. S obzirom na izvjesnu razinu sličnosti s posthumanizmom, pregled transhumanizma počinje analizom osnovnih pojmova: transhumanizam, posthumanizam, transhumano biće i posthumano biće. Nakon toga, transhumanizam se proučava iz perspektive različitih disciplina. Te su discipline: filozofija znanosti, metafizika, etika, filozofija uma, filozofija religije i filozofija politike. - This paper features an overview of the foundations of transhumanism. The transhumanist movement has existed since the end of the 20th century and espouses the use of technology for enhancing the human condition. Due to a certain level of similarity to posthumanism, this overview of transhumanism begins with an analysis of basic terminology: transhumanism, posthumanism, the transhuman being and the posthuman being. After that, transhumanism is studied from the perspectives of different disciplines. These disciplines are: philosophy of science, metaphysics, ethics, philosophy of mind, philosophy of religion and political philosophy.

Čudovišnost Bogočovjeka [Elektronička građa] : Žižekova ateistička "kristologija" / Hrvoje Petrušić.
Bibliografske bilješke uz tekst. - Sažetak ; Summary. - U našem radu analiziramo Žižekovo ateističko-materijalističko razumijevanje Hegelove filozofije Božjega utjelovljenja. Usredotočujemo se na pojmove čudovišnosti Krista i objave Božje smrti na križu. Pritom ističemo kristološki problematične točke takvog pristupa koji počiva kako na neutemeljenoj psihologizaciji sadržaja teologije, tako i na protuslovlju između unutarbožanskog/esencijalnog i ekonomijskog/spasenjskog poimanja Trojstva. - In our paper we analyze Žižek's atheist-materialistic understanding of Hegel's philosophy of the incarnation of God. We focus on the concepts of the monstrosity of Christ and revelation of God’s death on the cross. In doing so, we emphasize the Christologically problematic points of such an approach, which rests both on the unfounded psychologization of the content of theology, and on the contradiction between the intra-divine/essential and economic/salvific understanding of Trinity.

Filozofijska dimenzija pripovjednog sadržaja videoigara [Elektronička građa] / Luka Perušić.
Bibliografske bilješke uz tekst ; bibliografija: str. 74-77. - Sažetak ; Summary. - U radu se iznose kategorije prisutnosti filozofijske dimenzije u pripovjednom sadržaju videoigara s ciljem postavljanja temelja za pomnije promišljanje praktičkog i povijesnog odnosa filozofije i videoigara. Uvodno se opisuje pojavljivanje filozofijske dimenzije putem pripovjednog sadržaja pete generacije videoigara (1993.–2001.) te naznačuje važnost toga događanja. Središnje mjesto rada donosi opise kategorija prisutnosti, razlikujući (1) videoigre koje svojim pripovjednim sadržajem svraćaju pozornost na probleme filozofijske prirode, (2) videoigre koje unutar svog pripovjednog sadržaja laički filozofiraju o problemima filozofijske prirode te (3) videoigre koje se za potrebe svojeg pripovjednog sadržaja služe stručnom filozofijskom građom. Zaključno se u osnovnim crtama razmatra problem kategorije videoigara kao potpunih filozofijskih djela, takvih u kojima bi se uklanjanjem njihove filozofijske dimenzije u potpunosti raspali pripovjedni sadržaj i igraće mehanike te bi u potpunosti izgubile svoj smisao. - In the paper, laid out are the categories of the presence of the philosophical dimension of narrative content in video games, to establish a ground for more thorough thinking of practical and historical relation of philosophy and video games. In the introductory, described is the appearance of the philosophical dimension of the narrative content in the fifth generation of video games (1993–2001), and the importance of that happening is highlighted. The central part of the paper describes the categories of the presence, differentiating among (1) video games that use its narrative content to focus attention to issues of philosophical nature, (2) video games that have content within which they philosophise in layman terms about philosophical problems, and (3) videogames that apply professional philosophy to construct narrative content. Conclusively, the paper briefly discusses the issue of the category of games as complete philosophical works, understood in such a way that by removing their philosophical dimension both their narrative content and playing mechanisms would collapse and they would fully lose their meaning.

Humanizam i egzistencijalizam kao humanizam [Elektronička građa] : Abdulah Šarčević i Jean-Paul Sartre / Esko Muratović.
Bibliografske bilješke uz tekst. - Sažetak ; Abstract. - Imajući u vidu općeprihvaćeno vrednovanje i značenje pojmova humanuma i egzistencije, u ovom radu kompariramo filozofiju humaniteta Abdulaha Šarčevića i egzistencijalizam kao humanizam Jean-Paula Sartrea te ukazujemo kako na filozofsko-vrijednosnu paradigmatiku danih promišljanja, tako i na zasebne etičko-epistemičke specifičnosti, kao i na srodnosti između ovih humanističko-misaonih svjetonazora realiziranih unutar problematike antropo-metafizičkih i etičko-moralnih sagledavanja Šarčevićeve koncepcije humanizma u odnosu na Sartreov egzistencijalistički viđen humanizam. - Taking into consideration the accepted evaluation and the meaning of the concepts of humanum and existence, in this paper we compare Abdulah Šarčević’s philosophy of humanity and Jean-Paul Sartre’s existentialism as humanism, and point out both the philosophical value paradigm of given reflections and the separate ethical-epistemic specificity, as well as the affinities between these humanistic intellectual worldviews, realised within the problem of anthropo-metaphysical and ethical-moral perceptions of Abdulah Šarčević’s conception of humanism in relation to Jean-Paul Sartre’s existentialistically seen humanism.

Misliti revoluciju kao stvaranje univerzalnog – neetatističkog, nepredstavničkog, neidentitetnog – prostora politike "za sve" [Elektronička građa] / Lana Zdravković.
Bilješke uz tekst. - Bibliografske bilješke uz tekst ; bibliografija: str. 164-166. - Sažetak ; Abstract. - U radu se razmatra mogućnost mišljenja i prakticiranja revolucionarne politike u suvremeno doba, kroz osvrt na naslijeđe revolucionarne misli prakse 20. stoljeća te revolucionarne događaje u 21. stoljeću koji eksperimentiraju s konstitucijom revolucionarne moći bez zauzimanja vlasti. Izlazeći iz povijesne situacije obilježene tvrdnjom da revolucija ‘jede svoju djecu’, tvrdim kako istinska revolucija ne znači preuzimanje vlasti, već suprotno, ukidanje instance koncentrirane moći. Revoluciju treba nanovo osmisliti te je postaviti na kartu povijesti kao emancipacijski proces uspostavljanja politike jednakosti, što znači stvaranje univerzalnog – neetatističkog, nepredstavničkog, neidentitetnog – prostora politike ‘za sve’ odnosno za ‘bilo koga’, bez Drugoga. To pretpostavlja osmišljavanje i redefiniranje revolucionarnog subjekta, revolucionarne metode i revolucionarne organizacije. - The paper considers the possibility of rethinking and practising revolutionary politics in contemporaneity, through a look at the legacy of 20th-century revolutionary thought-practice and revolutionary events in the 21st century, which experiment with the constitution of revolutionary power without seizing the governmental power. Going from the historical situation, that the revolution “eats its children”, I argue that a true revolution does not mean taking power, but on the contrary, abolishing the instance of concentrated power. The revolution must be reconceived and put on the map of history as an emancipatory process of establishing a policy of equality, which is the creation of a universal space of politics for ‘all’ or ‘anyone’ without the Other. This presupposes the conceptualisation and redefinition of the revolutionary subject, the revolutionary method, and the revolutionary organization.

Na rubu igrivosti [Elektronička građa] : egzistencija i transcendencija u filmu eXistenZ / Ante Jerić. - Ilustr.
Tema broja: Filozofija pokretnih slika (I.). - Bibliografske bilješke uz tekst ; bibliografija: str. 455-456. - Sažetak ; Abstract. - Filozofija i znanstvena fantastika kao različiti diskursi na različite načine koriste protuintuitivne scenarije. Filozofija nastupa fundacijski u pokušaju utemeljivanja protuintuitivnih scenarija i dokazivanja njihove koherentnosti, dok znanstvena fantastika kao transmedijalni fikcionalni žanr pretpostavlja njihovu koherentnost i nastupa pragmatički prilikom pripovijedanja o tome kako bi to bilo kad bi se oni obistinili. Ovaj rad posvećen je analizi znanstveno-fantastičnog filma Davida Cronenberga eXistenZ (1999). U njemu branim dvije teze. Kritičko-teorijska teza: Cronenberg smatra da život u kasnom kapitalizmu biva organiziran sukladno logici igre, predočava tu logiku ovim fikcionalnim scenarijem i prokazuje je kao nepoželjnu. Metafizička teza: Cronenbergov dijegetski svijet donosi novu, iako ne originalnu, artikulaciju skepticizma kao starog filozofskog problema. Pokušaj fundiranja metafizičkih pretpostavki ovog dijegetskog svijeta reanimira kartezijanski interakcionistički dualizam i kantovski transcendentalni idealizam kao dvije dobro poznate i utvrđene filozofske pozicije. - Philosophy and science fiction are two separate discourses that use counter-intuitive scenarios in two distinct ways. Where philosophy endeavours to ground counter-intuitive scenarios, science fiction as a transmedial fictional genre acts in a pragmatic and exploratory manner by seeking to imagine what it would be like if they were real. In this paper, I analyse David Cronenberg’s science fiction film eXistenZ, and defend two theses. The critical-theoretical thesis: Cronenberg thinks society is being gamified and seeks to dramatise the process of gamification along with its pitfalls. The metaphysical thesis: Cronenberg’s diegetic world brings about a new articulation of the scepticism as an old philosophical problem. An attempt to excavate the metaphysical presuppositions of this work reanimates Cartesian interactionist dualism and Kantian transcendental idealism, as two well-known philosophical positions.

KUŠAR, Stjepan
Objava u filozofiji? [Elektronička građa] : Uvid u Schellingov pojam objave / Stjepan Kušar.
Tema broja: Schellingova filozofija - izabrani problemi. - Bibliografske bilješke uz tekst. - Sažetak ; Summary. - U članku se daje ocrt Schellingova poimanje objave; ono nije svedeno na teološki shvaćen pojam objave, nego ga pokazuje u širini autorove filozofske misli, od njegovih filozofskih početaka preko filozofije slobode pa do pozitivne filozofije. Pojam objave pokazuje se u svojoj tijesnoj povezanosti s poimanjem slobode – Božje i čovječje – i s mogućnošću i potrebom da se promišlja umu onostrani Apsolut a da nije »ukonačen« u imanenciju uma i njegova umovanja. Objava je shvaćena kao slobodna povijesna manifestacija Apsoluta, ponuda i apel čovječjoj slobodi i čovjekovu djelovanju u povijesti; ona je također moment života Boga koji sam ispostavlja stvorenje i ide mu ususret te ga vodi k cilju: da on, Bog, bude sve u svemu. - Im Artikel werden die tragenden Konturen des Offenbarungsbegriffs im Denken Schellings hervorgehoben. Der Begriff hat den christlichen Hintergrund, wird aber von Schelling nicht auf konfessionelle Ebene festgelegt oder reduziert. Schelling nimmt ihn als Realität in der geschichtlichen Erfahrung der Menschheit; als solcher ist er interessant für die Philosophie. Das Thema der Offenbarung markiert bereits die erste Periode des Schellingschen Denkens: mit ihm wird die erkenntnismässige Entdeckung der Unbedingtheit und Autonomie der menschlichen Freiheit verbunden und zwar im Zusammenhang mit dem deutsch-aufklärerischen Verständnis der christlichen Religion als Erzieherin des Menschengeschlechts in moralibus. In der zweiten Periode, die man mit Schellings Freiheitsschrift beginnen und mit den Weltaltern fortsetzen lässt, wird der Offenbarungsbegriff im Zusammenhang mit der Problematik des Bösen, der Freiheit und der Schöpfung behandelt. Er signalisiert die Freiheit des Absoluten und seiner schöpferischen Wirkung und Präsenz in Natur und (Religions)Geschichte der Menschheit – allerdings wird das Böse als notwendiges Moment der Offenbarung verstanden. In der letzten Periode seines Denkens (Philosophie der Mythologie und der Offenbarung) behandelt Schelling die Offenbarung (vor allem Offenbarung in Christo) als freie geschichtliche Manifestation des Absoluten, die zugleich als Angebot und Apel an seine freie Annahme von Seiten des Menschen verstanden und dargestellt wird. Die positive Philosophie Schellings ist keineswegs eine verkappte christliche Theologie; mit einem gewissen Recht könnte man sie vielleicht als Philosophie der christlichen Religion nennen.

VRANEŠEVIĆ, Goran
Pravo slobodne volje [Elektronička građa] : Hegel o stvaranju i vlasništvu / Goran Vranešević.
Bibliografske bilješke uz tekst ; bibliografija: str. 41-42. - Sažetak ; Summary. - U članku se ističe uloga vlasništva u uspostavljanju slobodne volje. Ljudska sloboda obično se shvaća kao sposobnost pojedinca za proizvoljno donošenje odluka. Iako se čini da se radi o svjesnim akcijama, akcijama u kojima smo najbliže sebi, ipak nismo svjesni uzroka kojim se utvrđuju ove akcije. Ipak, umjesto da izgladimo vrijednosnu podjelu između slobode i nužnosti, naš je cilj objasniti kako je logika slobode imanentno vezana za nužnost izlaska izvan sebe. Hegel nije prvi koji je pokazao tu logiku, ali bio je najdosljedniji u iznošenju ideje slobode kao postajanje drugim. Za njega, biti slobodnom osobom, subjektom, znači eksternalizirati našu volju u neovisne vanjske stvari i time steći vlasništvo nad njima. Sloboda, dakle, nije individualna kvaliteta, već društveni princip, jer vlasnička prava mogu postojati samo u intersubjektivnim odnosima. U tom kontekstu, postavlja se pitanje: kako je u okolnostima gdje je subjektivnost proizvod vlasništva i dalje moguće stvoriti nešto iz ničega?. - The article highlights the role of property in the establishment of free will. Human freedom is usually understood as individual’s capacity for arbitrary decision- making. While it seems that we are dealing with conscious actions, actions where we are closest to ourselves, we nonetheless remain unaware of the causes whereby these actions are determined. But instead of reconciling the age old divide between freedom and necessity, our aim is to expound how the logic of freedom is immanently bound to the necessity to go outside oneself. Hegel was not the first to demonstrate this logic, but was the most consistent in laying out the idea of freedom as self-othering. For him, being a free person, subject, means to externalize our will into a non-independent extraneous things and thereby obtain ownership over them. Freedom is therefore not an individual quality, but a societal principle as property rights can only exist in intersubjective relationships. In this context, the following question comes to the fore: how is in circumstances where subjectivity is a product of ownership still possible to create something out of nothing?.

DOMAZET, Anđelko
Religijski pluralizam kao trajni teološki izazov za Crkvu i njezinu teologiju religija [Elektronička građa] / Anđelko Domazet.
Bibliografske bilješke uz tekst. - Sažetak ; Summary. - Sve prisutniji kulturalni i religijski pluralizam neminovno postavlja pitanje odnosa kršćana prema rastućoj religioznoj pluralizaciji društva u kojem žive. U ovom tekstu pokušava se ukazati na teoretski i praktični doprinos koji teološka refleksija može dati kako bi se izazov religijskog pluralizma mogao vidjeti u ispravnom svjetlu tako da iz teoloških razmišljanja može slijediti konkretna politička i religijska praksa u društvu. Polazeći od činjenice da kršćani svagdje u svijetu žive u sva­ko­dnev­nom egzistencijalnom kontaktu sa sljedbenicima drugih religija, Katolička Crkva, počevši od Drugoga vatikanskog koncila, intenzivno raspravlja o teološkom vrjednovanju fenomena religijskog pluralizma i samoshvaćanju kršćanstva naočigled religijske povijesti čovječanstva. Budući da je religijski pluralizam objektivni teološki problem, u prvom dijelu rada autor analizira tri uobičajena religijsko-teološka nacrta ili modela koje nudi današnja teologija religija u pokušaju da odgovori na pitanje kakav bi trebao biti stav Crkve i kršćana prema religijskom pluralizmu: pretkoncilsko stajalište prema drugim religijama (ekskluzivistički ekleziocentrizam), pristup Drugoga vatikanskog koncila i poslijekoncilske teologije (inkluzivistički kristocentrizam) te pogled na druge religije predstavnika takozvane pluralističke teologije religija (pluralistički teocentrizam). U kontekstu religijskog pluralizma Crkva je kao zajednica vjernika pozvana potvrđivati vlastiti kršćanski identitet u dijalogu s postojećim religijama i kulturama u kojima kršćani žive. Stoga se u drugom dijelu rada, osim opisane trostruke klasifikacije pristupa teologiji religija, sažeto predstavljaju religijsko-teološki nacrti dvojice njemačkih katoličkih teologa. - Progressingly present cultural and religious pluralism inevitably raises the question of the attitude of Christians towards the growing religious pluralization of the society in which they live. This text tries to point out the theoretical and practical contribution that theological reflection can offer so that the challenge of religious pluralism can be seen in the right light and so that concrete political and religious practice in society could follow from theological reflections. Starting from the fact that Christians everywhere in the world live in daily existential contact with followers of other religions, the Catholic Church, starting from the Second Vatican Council, intensively discusses the theological evaluation of the phenomenon of religious pluralism and self-understanding of Christianity in the face of religious history of mankind. Considering the fact that religious pluralism is an objective theological problem, in the first part the author analyzes three common religious-theological drafts or models offered by today's theology of religions trying to answer the question of what should be the attitude of the Church and Christians towards religious pluralism: pre-Council attitude towards other religions (exclusivist ecclesiocentrism), the approach of the Second Vatican Council and post-Council theology (inclusivist Christocentrism) and a view of other religions of the representatives of the so-called pluralistic theology of religions (pluralistic theocentrism). In the context of religious pluralism, the Church, as a community of believers, is called to affirm its own Christian identity in dialogue with the existing religions and cultures in which Christians live. Therefore, in the second part of the paper, aside from the described triple classification of approaches to the theology of religions, the religious-theological plans of two German Catholic theologians are summarized.

PROLE, Dragan
Što je to trubadurska radost? [Elektronička građa] / Dragan Prole.
Bibliografske bilješke uz tekst. - Sažetak ; Abstract. - U prvom dijelu članka, autor ispituje pitanje trubadurske subjektivnosti. Subjekt pjesme najavljuje samogubljenje, napuštanje postojećeg stanja stvari i samopredavanje, ali u tome ne vidi tragediju, već izvor istinske radosti. Ljubav zaslužuje žrtvu, ona je vrijedna cjelokupnog ljudskog htijenja, ali nije konvencionalna ljubav, nije ni bračna ni porodična, već je eterična i poetična ljubav prema Gospi. Za sve što može biti vezano uz takvu ljubav smatramo da je daleko prikladniji prijevod radosna nauka jer preciznije označava trubadursku poantu od uobičajenog prijevoda vesela nauka. Ono što posebno začuđuje kod naslijeđenog rješenja potpuno je promašivanje trubadurske posebnosti jer se riječ nauka može dovesti s njom u vezu jedino ako se prethodno stavi pod znakove navoda (što je i Nietzsche izričito učinio). Riječju, autor zaključuje da je demokratski naučnik sretan i optimističan, dok Nietzscheov »radosni« naučnik ne preza svima javno pokazati svoje patničko lice. Trubadurska patnja zbog daleke i neostvarive ljubavi neobično je blizu Nietzscheovoj patnji u suvremenom svijetu koji kao da nije u stanju živjeti u svijetu dalekog i odsutnog Boga. - In the first part of the paper, the author tackles the question of troubadour subjectivity. The subject of the poem announces the losing of oneself, abandonment of the existing state of affairs and self-surrender, but sees no tragedy in it, for a source of genuine joy. Love deserves sacrifice, it is worthy of all human desire, but it is not a conventional love, neither marital nor family love, rather, it is an ethereal and poetic love for Our Lady. For everything that may be related to such love, we believe that a far more appropriate translation of gaya scienza is a joyful lesson, for it signifies far more to mark the troubadour point than the usual [Croatian/Serbian] translation cheerful doctrine. What is notably striking about the inherited solution is the complete misapprehension of the troubadour point, as the word science can only be associated with the troubadour wisdom if it is previously put in quotes (which Nietzsche explicitly does). In short, the author concludes that a democratic scientist is happy and optimistic, while Nietzsche’s »joyful« scientist does not hesitate to show his anguished face publicly. The troubadour’s anguish for distant and unrealizable love is peculiarly close to Nietzsche’s suffering in a modern world that seems unable to live in a world of a distant and absent God.

RADOJČIĆ, Saša
Tema sveučilišta u Crnim bilježnicama Martina Heideggera [Elektronička građa] / Saša Radojčić.
Bibliografske bilješke uz tekst ; bibliografija: str. 46-47. - Sažetak ; Summary. - Bilješke koje je Martin Heidegger unosio u takozvane "crne bilježnice" potakle su, netom nakon objavljivanja, intenzivne diskusije, osobito oko pitanja antisemitizma i nacionalsocijalizma. Je li se Heideggerova osobna naklonost ka ovim ideologijama odrazila i na njegovo filozofsko djelo? U ovom ogledu razmatra se jedna, s ovim pitanjima povezana, važna tema u Crnim bilježnicama – tema sveučilišta. Ona postaje frekventnija u tri navrata, obilježena značajnim događajima u Heideggerovoj profesionalnoj biografiji: preuzimanjem funkcije rektora sveučilišta u Freiburgu (1933.), napuštanjem te funkcije (1934.) te isključenjem iz nastave u sklopu poratne denacifikacije Njemačke (1945.). Pokazuje se da shvaćanje sveučilišta u Crnim bilježnicama odgovara idejama predočenim u Heideggerovu rektorskom govoru, kao i da to shvaćanje nije jednako nacionalsocijalističkom, već izražava filozofovo "narodnjačko" misaono usmjerenje. Iako posjeduje neke elemente vokabulara koji su bili prisutni u nacističkoj propagandi, Heidegger svoje stavove o stvarnosti i budućnosti sveučilišta integrira s drugim svojim idejama – kritikom svođenja znanja na tehničke aspekte, kritikom izoliranja znanosti u samostalna područja i uopće kritikom zapadnjačkog mišljenja. - The notes that Martin Heidegger made in the so-called Black Notebooks stimulated, immediately after publication, intense discussions, especially on the issue of anti-Semitism and National Socialism. Does Heidegger’s personal fondness for these ideologies reflect on his philosophical work? In this essay, one important topic related to these issues in Black Notebooks is discussed – the topic of university. It became more frequent on three occasions, marked by significant events in Heidegger’s professional biography: taking over as rector of the University of Freiburg (1933), leaving that position (1934), and exclusion from teaching as part of the postwar denazification of Germany (1945). It turns out that the understanding of the university in the Black Notebooks corresponds to the ideas presented in Heidegger’s rector’s speech, and that this understanding is not equally National Socialist, but expresses the philosopher’s “populist” thinking. Although he possesses some elements of vocabulary that were present in Nazi propaganda, Heidegger integrates his views on the reality and future of the university with his other ideas – a critique of reducing knowledge to technical aspects, a critique of isolating science into independent fields, and a critique of Western thought.

Biološke osnove placebo-učinka [Elektronička građa] / Nikolina Šaravanja, Dragutin Ivanec. - Ilustr.
Bibliografske bilješke na kraju teksta. - Sažetak ; Summary. - Teorijski neutralan tretman koji dovodi do pozitivnih ishoda naziva se placebo-učinak. Takav je učinak opažen i dokumentiran kako u laboratorijskim tako i u kliničkim istraživanjima, kod različitih zdravstvenih simptoma i patoloških stanja. U tradicionalnom poimanju placebo-učinka podrazumijevali su se učinci koje primarno treba metodološki kontrolirati kako bi se što točnije procijenio učinak teorijski utemeljenih terapijskih pristupa. U modernijim shvaćanjima riječ je o realnom učinku koji ima svoje opažljive psihološke procese i fiziološke mehanizme. Može biti samostalan ili pak dio svih drugih terapijskih postupaka. Na temelju toga, u zdravstvenom kontekstu cilj ne bi trebao biti tek kontrolirati takav učinak, već ga što bolje razumjeti kako bi se eventualno mogao primjenjivati uz poznate i teorijski utemeljene zdravstvene tretmane. U ovom tekstu naglasak je na opisu bioloških mehanizama i procesa koji pridonose placebo-učinku. Dominantno je opisano područje placebo-učinka kod boli, ali su opisani i slučajevi placebo-učinka i kod nekih drugih patoloških stanja gdje su istraživani biološki mehanizmi placeba, poput psihičkih bolesti i poremećaja te Parkinsonove bolesti. Kod svih placebo-učinaka postoji dosta indikatora da je riječ o složenom odnosu psiholoških čimbenika koji u interakciji s fiziološkim procesima pridonose realnom poboljšanju zdravstvenih ishoda. - Theoretically neutral treatment that leads to positive outcomes is called the placebo effect. Such an effect has been observed and documented in both laboratory and clinical studies in a variety of health symptoms and pathological conditions. In the traditional notion of the placebo effect, those were considered effects that should be primarily methodologically controlled in order to assess the effect of theoretically grounded therapeutic approaches as precisely as possible. In more modern approaches, it is a real effect that has its observable psychological and physiological mechanisms and processes. It can be independent or a part of all other therapeutic procedures. Based on this, in a health context, the goal should not be only to control such an effect but to understand it as well as possible so it could possibly be used with known and theoretically based health treatments. In this article the emphasis is on describing biological mechanisms and processes that contribute to the placebo effect. The area of an analgesic placebo effect is dominantly described, but cases of the placebo effect have also been described in cases of some other pathological conditions where the biological mechanisms of a placebo effect have been investigated, such as mental illnesses and disorders, or Parkinson’s disease. For all placebo effects, there have been many indicators that there is a complex relation between psychological factors which, in the interaction with physiological processes, contribute a real improvement in health outcomes.

Cognitive functions in combat posttraumatic stress disorder [Elektronička građa] / Ana Havelka Meštrović, Marina Domijan, Vlatko Mičković, Zoran Lončar. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - Posttraumatic stress disorder (PTSD) is associated with changes in cognitive functions. The aim of the study was to investigate differences in cognitive abilities between PTSD patients and healthy controls. As PTSD is often accompanied by comorbidity, the PTSD patients with comorbid diagnoses were also included in our study. The study participants included 254 Croatian combat veterans (60 PTSD and 194 PTSD plus comorbidity) and control group of 125 healthy Croatian military and civilian pilots. The diagnosis of PTSD was made by clinical scale for PTSD assessment (CAPS), while cognitive abilities were measured by Wechsler intelligence scale (WAIS-III-R) and Rey test (ROCFT). The study results have confirmed that there is a significant difference in cognitive functions between the PTSD patients and healthy controls regarding age and education. The PTSD patients (PTSD only and PTSD with comorbidity) have shown lower general intellectual abilities, reduced capacity of working, numerical and visual memory, and decreased executive functions when compared to healthy controls. These results are an additional contribution to a better understanding and determination of changes in cognitive functions that occur in combat PTSD as a result of traumatic stress. - Cilj istraživanja bio je dokazati razlike u kognitivnim sposobnostima između bolesnika s PTSP-om i zdravih ispitanika. S obzirom da je PTSP često praćen komorbidnim dijagnozama, u ispitivanje su uključeni bolesnici s PTSP-om koji imaju komorbidnu dijagnozu. Među sudionicima studije bila su 254 hrvatska ratna veterana (60 PTSP i 194 PTSP + komorbiditet) dok su kontrolnu skupinu činili 125 hrvatskih vojnih i civilnih pilota. Dijagnoza PTSP-a procjenjivala se je skalom za ocjenu PTSP-a (CAPS), dok su kognitivne sposobnosti bile mjerene Wechslerovom obavjesnom skalom (WAIS-IIII-R) i Reyevim testom (ROCFT). Rezultati ispitivanja potvrdili su postojanje značajnih razlika u kognitivnim funkcijama između bolesnika s PTSP-om i zdravih ispitanika s obzirom na dob i obrazovanje. Bolesnici s PTSP-om (samo PTSP i PTSP + komorbiditet) pokazali su smanjene opće intelektualne sposobnosti, smanjeni kapacitet radne, numeričke i vizualne memorije te smanjene izvršne funkcije u usporedbi sa zdravim kontrolnim ispitanicima. Ti su rezultati dodatni doprinos boljem razumijevanju i definiranju promjena kognitivnih funkcija te boljem terapijskom pristupu PTSPu kao posljedice traumatskog stresa.

Construct-related validity of the emotional skills and competence questionnaire - children's form [Elektronička građa] : (ESCQ-C) / Tamara Mohorić. - Graf. prikazi.
Tema broja: Emocionalna inteligencija. - Bibliografija: str. 163-166. - Summary. - Social and emotional skills have an important role in children’s general functioning and social relationships (e.g., with peers, and family). Questionnaires measuring these competencies should be carefully developed and validated and be in accordance with the developmental stage of children. The Emotional Skills and Competence Questionnaire – Children’s form (ESCQ-C) is a self-report measure of one’s ability to perceive and understand emotions, to express and label emotions, and to manage and regulate emotions. It was developed within the theoretical framework from the Mayer and Salovey (1997) emotional intelligence model. Structural validity of the ESCQ-C was assessed in a sample of preadolescent children (N = 639, 53% girls, Mage = 11.24, SDage = 0.71), and convergent validity was tested by correlating ESCQ-C subscales scores with the social, emotional and academic self-efficacy (The Self-Efficacy Questionnaire for Children, Muris, 2001). Our results suggest the four-factor structure for the ESCQ-C. Manage and regulate emotions subscale was divided into two subscales: the self-perceived ability to regulate one’s own emotions and other’s emotions. Correlations with the self-efficacy scales were moderate, suggesting good convergent validity. The ESCQ-C can be considered a valid measure of the emotional skills and competences for children.

Croatian translation and validation of the Mind-Wandering Questionnaire (MWQ) [Elektronička građa] / Marina Perković Kovačević, Mario Ćurković, Dražen Gorjanski, Ivon Matić. - Graf. prikazi.
Bibliografija: str. 554-558. - Summary ; Sažetak. - This research aimed to translate and validate the Mind-Wandering Questionnaire (MWQ) to the Croatian language, and to provide preliminary data on its reliability, factor structure and convergent validity in a sample of Croatian students. After translation and adaptation, the Croatian version of the MWQ was administered to 451 eight-grade elementary school students (239 female and 212 male participants). With the MWQ, we administered the Emotional Skills and Competence Questionnaire (ESCQ-45). Results show high internal consistency of the Croatian translation of the MWQ. Confirmatory factor analysis supports an unidimensional model. Convergent validity was supported by a significant negative correlation between MWQ and Emotional Skills and Competence Questionnaire. We propose further investigation of psychometric properties of the Croatian translation of the MWQ and investigating test-retest reliability as well as discriminant validity of the Questionnaire. - Cilj je ovoga istraživanja bio prijevod i validacija Upitnika lutanja uma (engl. Mind Wandering Questionnaire, MWQ) na hrvatski jezik te predstavljanje preliminarnih podataka o njegovoj pouzdanosti, strukturi i konvergentnoj valjanosti na uzorku hrvatskih učenika. Nakon prevođenja i prilagodbe hrvatski je prijevod MWQ-a primijenjen na 451 učeniku osmih razreda osnovne škole (239 djevojčica i 212 dječaka). Usporedno s MWQ-om primijenjen je i Upitnik emocionalne kompetentnosti (ESCQ-45). Rezultati pokazuju visoku pouzdanost hrvatskoga prijevoda MWQ-a, dok je konfirmatornom faktorskom analizom potvrđen jednodimenzionalni model. Značajna negativna korelacija MWQ-a i Upitnika emocionalne kompetentnosti upućuje na dobru konvergentnu valjanost hrvatskoga prijevoda upitnika. Daljnjim istraživanjima potrebno je dodatno provjeriti psihometrijska svojstva hrvatskoga prijevoda MWQ-a, posebno test-retest pouzdanost te diskriminantnu valjanost upitnika.

Cross-cultural and gender measurement invariance of the intrapersonal and interpersonal emotional competence questionnaire [Elektronička građa] / Andreja Avsec, Irina Belasheva, Jiri Cenek, Azizuddin Khan, Tamara Mohorić, Vladimir Takšić, Gaja Zager Kocjan. - Graf. prikazi.
Tema broja: Emocionalna inteligencija. - Bibliografija: str. 183-187. - Summary. - The Intrapersonal and Interpersonal Emotional Competence Questionnaire (IIECQ) was developed from the Emotional Skills and Competence Questionnaire, addressing some of its content issues. Measurement invariance of the two-factor IIECQ model (interpersonal and intrapersonal emotional competence factors) was examined across countries and gender groups using a sample of 998 students from five different countries (Slovenia, Russia, Croatia, India, and theCzech Republic). Our results supported partial scalar invariance of the IIECQ across countries with three items having varying intercepts in different countries. Scalar invariance was fully confirmed across gender groups. Latent means for the two IIECQ factors were compared between the five countries and the two gender groups. While men and women reported similar levels of intrapersonal and interpersonal emotional competences, significant differences were observed between some of the countries. To assess the construct validity of the IIECQ, correlations were examined between the IIECQ subscale scores and the measures of emotion regulation, personality, and well-being. In general, correlations were low to moderate and in accordance with expectations, showing adequate convergent validity of the new scales. Overall, the IIECQ represents a psychometrically sound measure of the intrapersonal and interpersonal emotional competences, which are measured in the same way across the five countries examined as well as across genders.

Cross-cultural questionnaires and the necessity of using native translators [Elektronička građa] : a Croatian-Swedish case / Bo Molander, Stefan Holmström, Vladimir Takšić. - Graf. prikazi.
Tema broja: Emocionalna inteligencija. - Bibliografija: str. 197-198. - Summary. - In this paper, we discuss problems of comparing two European cultures in a study of emotional intelligence by relying on traditional back translation of the questionnaire and the scales used in the study (Holmström, Molander, & Takšić, 2008; Molander, Holmström, & Takšić, 2009, 2011). We compared Croatian and Swedish university students in using The Emotional Skills and Competence Questionnaire, which is an original Croatian questionnaire (Takšić, 1998; Takšić, Mohorić, & Duran, 2009) based on the emotional intelligence theory of Mayer and Salovey (1997). Initially, we found small differences in responding to emotional items between the two countries as revealed by traditional statistical methods. Here we illustrate a large increase of the initial differences by applying differential item functioning (DIF) procedures (Zumbo, 1999), and then reducing again differences by taken several important steps in analyzing the translated items. Most important in these latter procedures was a new translation to Swedish by a native Croatian-speaking translator.

Difficulties in emotion regulation and attitudes towards risky driving in a group of pre-licensed drivers [Elektronička građa] / Kristina Žardeckaitė-Matulaitienė, Auksė Endriulaitienė, Justina Slavinskienė, Rasa Markšaitytė, Laura Šeibokaitė. - Graf. prikazi.
Bibliografija: str. 351-356. - Summary ; Sažetak. - Over-representation of novice drivers in motor-vehicle crashes encourages researchers to look for all possible psychological causes which might be targeted in prevention. The present study is aimed to explore the associations between difficulties in emotional regulation and attitudes towards risk-taking while driving in a group of pre-licensed drivers. The sample involved 475 driver’s licence candidates who completed the self-reported questionnaire with the Difficulties in Emotion Regulation Scale (DERS) and the Scale of Risk-Taking Attitudes to Driving. Structural equation modelling showed that difficulties in emotion regulation were statistically significant predictors of all measured risk-taking attitudes to driving (over speeding, drunk driving, showing off driving skills, violation of traffic rules, joyriding and positive attitude towards traffic flow) for both males and females. These findings add to the gap in the literature and confirm that emotion regulation difficulties might be the important target addressed in early intervention. Increased emotional competence of pre-licensed drivers might contribute to safer driving and improved road safety. - Velik postotak vozača početnika u prometnim nezgodama potakla je istraživače na ispitivanje mogućih psihičkih uzroka, na koje bi se moglo djelovati u sklopu preventivnih programa. Cilj je ovog istraživanja bio ispitati povezanost poteškoća u emocionalnoj regulaciji i stavova prema rizičnoj vožnji kod pristupnika vozačkom ispitu, odnosno osoba koje još nemaju vozačku dozvolu. U uzorak je uključeno 475 pristupnika vozačkom ispitu muškoga i ženskoga spola, koji su ispunili Upitnik poteškoća u regulaciji emocija (DERS) i Skalu rizičnih stavova o vožnji. Prema rezultatima strukturalnog modeliranja teškoće u emocionalnoj regulaciji značajan su prediktor svih mjerenih stavova o vožnji koja ometa ili ugrožava druge sudionike u prometu (prebrza vožnja, vožnja u pijanom stanju, kršenje prometnih pravila, obijesna vožnja i sl.). Ovi nalazi dopunjuju dosadašnja istraživanja i potvrđuju važnost rane intervencije teškoća u emocionalnoj regulaciji. Viša emocionalna kompetencija kandidata za vozački ispit može pridonijeti sigurnijoj vožnji i većoj sigurnosti na cesti.

Effects of measures of emotional intelligence on the relationship between emotional intelligence and transformational leadership [Elektronička građa] / Ljerka Hajncl, Dario Vučenović. - Graf. prikazi.
Tema broja: Emocionalna inteligencija. - Bibliografija: str. 129-134. - Summary. - The major purpose of the present study was to investigate the relationships between two measures of emotional intelligence: performance-based ability test, self-reported measure of ability emotional intelligence, and transformational leadership. Base on a sample of 177 middle-level and low-level leaders, in 16 organizations, the study tries to explain the role of emotional intelligence in the variance of transformational leadership style, after controlling for cognitive ability and five factors of personality. Vocabulary Emotion Test (VET-3), representing performance-based ability test of emotional intelligence, and Emotional Skills and Competence Questionnaire (ESCQ-45), representing self-report measure of emotional intelligence, TN-10 test of fluid intelligence and BFI - inventory of personality traits were administered to all supervisors in identifying their emotional intelligence, cognitive ability and personality traits. To evaluate the transformational leadership style, the short version of a Multifactor Leadership Questionnaire (MLQ X5) was used for 177 selfratings. The results show that VET-3 as the measure of ability EI has no relationship with transformational style. The results obtained in hierarchical regression analysis of self-ratings transformational leadership show that the personality traits were significant predictors but that selfreport measure of EI incrementally explained 5% of the variance of transformational leadership.

The effects of short-term emotional intelligence training on preschool teachers in Poland [Elektronička građa] / Marzena Martyniak, John Pellitteri. - Graf. prikazi.
Tema broja: Emocionalna inteligencija. - Bibliografija: str. 92-94. - Summary. - The development of emotional intelligence (EI) in preschool teachers is important because of the influence on classroom environment, student engagement and child development. This cluster sample experimental study included teachers (all female) in public and private nursey and preschools in Warsaw, Poland. The treatment group (N = 60) interventions included three monthly workshop training in EI that was supported by daily exercises for four weeks following the training in contrast to the control group (N = 44) that did not receive any intervention. Pretest-posttest comparisons as measured by the Polish Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT) indicated treatment group increases in three of the four EI abilities (facilitation, knowledge and regulation) as well as the MSCEIT Strategic area. In posttest comparisons the treatment group was significantly higher than controls on the facilitation and regulation abilities and the strategic area. Results suggest that targeted interventions for teachers can improve EI abilities with short term training and hold promise for improved teacher development.

Explaining students' test anxiety and depression [Elektronička građa] : the role of family interaction quality / Jelena Čeko, Ina Reić Ercegovac. - Graf. prikazi.
Bibliografija: str. 14-16. - Summary. - To examine the relationship between the quality of family interactions and test anxiety and depression in a sample of 4th and 7th grade primary school pupils. Methods: The Scale of Depression for Children and Adolescents (SDCA, Vulić Prtorić, 2003a), The Subscale for Test Anxiety (STA, Vulić Prtorić, 2004a), and Scale of Interaction Quality within the Family (SIQF, Vulić Prtorić, 2004b) were used. Results: Older pupils were generally more depressed and anxious compared to the younger ones. However, the increase in depression was observed only in female pupils, whereas in male pupils, the levels of depression were generally stable, regardless of age. A similar pattern was found in test anxiety. Overall satisfaction with family, as well as the quality of interactions with mother and father was higher in fourth graders, compared to seventh graders. Female pupils assessed their mothers as more accepting, whereas male pupils assessed their fathers as more accepting than girls did. Maternal rejection was independent of gender, but paternal rejection was more prominent in boys, compared to girls. Higher maternal rejection and lower paternal acceptance were shown to be significant predictors for both depression and test anxiety. Conclusion: Results confirmed our hypothesis that early-adolescents, as well as girls, have more pronounced depressive and test-anxiety symptoms, when compared to younger children and boys. (Pre)-adolescents’ perceptions of family dynamics have an important role in explaining depressiveness and test anxiety, which implies their value in prevention of mental health problems in (pre)adolescents.

Glazbene preferencije prema modelu MUSIC [Elektronička građa] : povezanost s motivima slušanja glazbe i crtama ličnosti / Valnea Žauhar, Nikolina Levak. - Graf. prikazi.
Bibliografija: str. 333-336. - Sažetak ; Summary. - U ovom je istraživanju provjereno replicira li se petofaktorska struktura Modela glazbenih preferencija MUSIC (Rentfrow, Goldberg i Levitin, 2011), čije dimenzije odražavaju preferencije prema blagoj, nepretencioznoj, sofisticiranoj, intenzivnoj i suvremenoj glazbi, na hrvatskom uzorku mladih. Također, ispitano je replicira li se trofaktorska struktura Inventara motiva slušanja glazbe (Uses of Music Inventory, UMI, Chamorro-Premuzic i Furnham, 2007), koji uključuje emocionalno i kognitivno slušanje glazbe te slušanje glazbe u pozadini. Istraživanjem je ispitan odnos glazbenih preferencija, motiva slušanja glazbe i crta ličnosti. U prvom dijelu istraživanja 457 ispitanika (74.2 % ispitanica) prosječne dobi od 20 godina ispunilo je Inventar motiva slušanja glazbe te Petofaktorski inventar ličnosti (Big Five Inventory, BFI, Benet-Martinez i John, 1998). U drugom su dijelu istraživanja procjenjivali stupanj sviđanja za 25 glazbenih isječaka (Rentfrow i sur., 2011) pomoću kojih se ispituju glazbene preferencije. Rezultati ovog istraživanja uputili su na zadovoljavajuću strukturu modela MUSIC kad se u ispitivanje glazbenih preferencija uključio 21 isječak. Također, zadovoljavajućom se pokazala i trofaktorska struktura Inventara motiva slušanja glazbe. Povezanosti glazbenih preferencija i motiva slušanja glazbe s crtama ličnosti uglavnom su replicirane. Crte ličnosti pridonijele su objašnjenju varijance glazbenih preferencija povrh dobi i spola, a kao samostalni prediktori uglavnom su se istaknule otvorenost i ekstraverzija. Uz crte ličnosti, motivi slušanja glazbe objasnili su preferencije prema blagoj, intenzivnoj i suvremenoj glazbi. Pri tome, emocionalno slušanje predviđalo je preferencije prema blagoj glazbi, dok je kognitivno slušanje bilo negativni prediktor iste. - This study aimed to examine whether the five-factor structure of the MUSIC model (Rentfrow, Goldberg, & Levitin, 2011) including dimensions that reflect preferences for Mellow, Unpretentious, Sophisticated, Intense and Contemporary music replicates in a Croatian sample. Furthermore, the study aimed to examine the replicability of the three-factor structure of the Uses of Music Inventory (UMI, Chamorro-Premuzic & Furnham, 2007) including emotional, cognitive and background uses of music. Relationships between music preferences, uses of music and personality traits were investigated. In the first part of the study, in a sample of 457 participants (74.2 % female, Mage = 20.27 years) we administered the Uses of Music Inventory and the Big Five Inventory (BFI, Benet-Martinez & John, 1998). In the second part of the study, participants judged their liking of 25 excerpts of music (Rentfrow et al., 2011). The results showed the replicability of the five-factor MUSIC model when 21 excerpts of music are included in the analysis. The results showed the replicability of the three-factor structure of the Uses of music inventory, too. Relationships between music preferences, as well as between uses of music and personality traits were mainly confirmed. Personality traits explained music preference variances above age and gender, with openness to experience and extraversion being significant predictors. Uses of music additionally explained preferences for Mellow, Intense and Contemporary music only. Higher levels of emotional use of music and lower levels of cognitive use of music predicted increased preferences for Mellow music. Higher levels of cognitive use of music predicted increased preferences for Intense music. Lower levels of cognitive use of music and higher levels of emotional and background uses of music predicted preferences for Contemporary music.

Higher level of cognitive reserve reduces the risk of cognitive difficulties in healthy adults [Elektronička građa] / Ewa Małgorzata Szepietowska, Anna Kuzaka. - Graf. prikazi.
Bibliografija: str. 241-247. - Summary ; Sažetak. - The study was designed to investigate whether a level of cognitive reserve (CR) is associated with a level of cognitive competences in adults. Evidence from numerous earlier studies suggests that high CR, defined as previously acquired knowledge and experience, plays a protective role with respect to cognitive capacities in adults and senior citizens. Hence, it was hypothesised that a lower CR would predict lower cognitive capacities. The study involved 120 Polish healthy adults (75 women and 45 men) ranging in age from 40 to 85 years (M = 57.42; SD = 10.48). The applied CR index took into account formal education level, involvement in social, occupational and physical activity, and level of social support. The recorded data also included depression level (Beck Depression Inventory, BDI II) and cardiovascular status (hypertension: yes / no). The subjects’ current cognitive competences were assessed using Montreal Cognitive Assessment test (MoCA), Wechsler Adult Intelligence Scale (WAIS) subtests, verbal fluency tests and Dysexecutive Questionnaire, self-report version (DEX-S). Based on the subjects’ scores in cognitive tests, a cluster analysis was performed, and the participants were divided into two groups presenting lower cognitive level (LCL) and higher cognitive level (HCL). The LCL subjects were older than HCL and they had higher level of depression and lower CR. In order to determine whether lower level of CR is related to lower level of cognitive abilities in the adults, logistic regression analysis was carried out, also taking into account age, cardiovascular status and depression level. It was shown that the higher level of CR reduced the risk of cognitive deficits. Older age corresponds to poorer cognitive function. The findings showed no interaction between CR and age. Depression and health status did not predict level of cognitive abilities. - Cilj je ovog istraživanja bio ispitati je li kod odraslih ispitanika kognitivna zaliha povezana s razinom kognitivne kompetencije. Rezultati brojnih prethodnih istraživanja uputili su na zaštitnu ulogu velike kognitivne zalihe, operacionalizirane prethodno usvojenim znanjem i stečenim iskustvom, za očuvanje kognitivnih kapaciteta odraslih i starijih ljudi. U skladu s time, hipoteza je ovog istraživanja bila da će manja kognitivna zaliha predviđati niže kognitivne sposobnosti u odrasloj dobi. U istraživanju je sudjelovalo 120 zdravih odraslih ispitanika iz Poljske (75 žena i 45 muškaraca) raspona dobi od 40 do 85 godina (M = 57.42; SD = 10.48). Indeksom kognitivne zalihe obuhvaćena je razina formalnog obrazovanja, uključenost u socijalne, profesionalne i tjelesne aktivnosti te razina socijalne podrške. Također, prikupljeni su podaci koji se odnose na razine depresivnosti (Beckov inventar depresije) te kardiovaskularni status. Kognitivne kompetencije ispitanika ispitane su korištenjem Montrealske ljestvice kognitivne procjene, suptestova Wechslerova testa inteligencije za odrasle, testova verbalne fluentnosti i samoprocjenom izvršnih funkcija. Na temelju rezultata na testovima kognitivnih sposobnosti ispitanici su podijeljeni u skupine s nižom i s višom razinom kognitivnog funkcioniranja. Ispitanici s nižom razinom kognitivnog funkcioniranja bili su stariji, imali su višu razinu depresivnosti i manje kognitivne zalihe u usporedbi s ispitanicima s višom razinom kognitivnog funkcioniranja. S ciljem ispitivanja jesu li manje kognitivne zalihe povezane s nižim kognitivnim sposobnostima, provedena je logistička regresijska analiza. U obzir je pritom uzeta dob, kardiovaskularni status i razina depresivnosti ispitanika. Rezultati su pokazali da veća kognitivna zaliha smanjuje rizik od kognitivnih poteškoća. Starija dob povezana je sa slabijim kognitivnim funkcioniranjem, no nije dobivena interakcija kognitivne zalihe i dobi.

MESTRE, José M.
How to transversely develop ability emotional intelligence ability through school subjects? [Elektronička građa] : A theoretical proposal / José M. Mestre. - Graf. prikazi.
Tema broja: Emocionalna inteligencija. - Bibliografija: str. 33-41. - Summary. - Since emotional intelligence (EI) was developed in 1990, the field of Education took advantage of the possibilities of EI. Indeed, EI-specific programs proliferated and developed as socio-emotional learning programs (SEL). However, there is an alternative to realize non-specifically and longer and viability way for improving the implicit abilities of EI (AEI). The article claims to work a theoretical proposal to develop the AEI in compulsory education through the subjects. This proposal is based on the Cattell-Horn-Carroll theory of cognitive abilities (CHC). CHC abilities are stimulated by most of the mandatory subjects of both Primary and Secondary Schools. The second stratum of CHC model is composed of similar cognitive abilities as 1997-Ability Emotional Intelligence Model (perception, using, understanding, and managing emotions), which is different from trait EI approaches - that consider EI has personality traits as well. It has pointed out that the capacities of the CHC-model second stratum are connected to the capabilities of AEI. Therefore, any educational activity that optimizes perception, understanding, attentional control or planning is affecting the development of AEI. Promoting AEI involves hot information processing. It is convenient to use transversely hot information processing - this means that this information has special meaning for the people. Connecting hot information to mandatory subjects teaching would develop the abilities of EI. Both Sciences and Natural Sciences pedagogic devices can improve emotional perception. However, Social Sciences and Humanities foster both emotional understanding and knowledge. Finally, the different contingencies that occur in school life scenarios are suitable for training of emotional regulation.

COSTA, Ana
Implicit theories of emotional intelligence, ability and trait-emotional intelligence and academic achievement [Elektronička građa] / Ana Costa, Luísa Faria. - Graf. prikazi.
Tema broja: Emocionalna inteligencija. - Bibliografija: str. 56-61. - Summary. - This study examines the effect of the implicit theories of emotional intelligence and of emotional intelligence (EI; ability and trait EI) on students’ academic achievement (GPA). Five hundred twenty-three 10th graders (Mage = 15.5; SD = 0.67) completed measures of implicit theories (IT) and EI (performance and self-report). The results confirmed the direct effect of EI (ability and trait EI) on students’ GPA. Moreover, implicit theories of EI affected students’ trait EI and only indirectly affected students’ achievement. Multigroup analyses indicated that the IT and EI effects on students’ GPA were similar across students’ gender and socio-professional status. These findings underline the relevance of students’ implicit theories and EI and suggest their usefulness as strategies to foster academic success.

Ličnost i reakcija na iznenadni događaj [Elektronička građa] : efekti načina modeliranja fizioloških reakcija / Marko Tončić. - Graf. prikazi.
Bibliografija: str. 746-750. - Sažetak ; Summary. - Cilj je ovoga istraživanja bio ispitati interindividualne razlike u elektrodermalnim reakcijama na iznenadni podražaj. Za ispitivanje toga cilja korištene su različite metode procjene elektrodermalne reakcije. Procjena reakcije kao jednostavna razlika prosječne elektrodermalne razine prije i poslije podražaja uspoređena je s pristupima koji modeliraju krivulju elektrodermalne reakcije kroz vrijeme. Ispitana je povezanost takve reakcije, modelirane na različite načine, s upitničkim mjerama osobina ličnosti. U istraživanju je sudjelovalo 97 studenata u dobi od 18 do 28 godina, većinom ženskoga spola (60 %). Svaki je ispitanik ispunio kratku mjeru neuroticizma i ekstraverzije iz Petofaktorskoga inventara ličnosti (BFI; John i sur., 1991, 2008) te je sudjelovao u jednome laboratorijskome mjerenju elektrodermalne reakcije na iznenadni događaj u trajanju od 8 minuta. Elektrodermalna aktivnost modelirala se na tri načina: 1) kao razlika u reakcijama prije i poslije podražaja; 2) uključujući i linearne efekte vremena; 3) uključujući i kvadratne efekte vremena. Ishodi takvoga modeliranja korelirani su s upitničkim mjerama neuroticizma i ekstraverzije. Rezultati su pokazali da uzimajući u obzir efekte protoka vremena sama procjena krivulje elektrodermalne aktivnosti značajno bolje pristaje stvarnim izmjerenim podacima. Isto tako, procjene elektrodermalne reakcije koje uzimaju u obzir efekte protoka vremena rezultiraju višim prosječnim razinama i većim interindividualnim varijabilitetom. Tako modelirana elektrodermalna reakcija (linearno i kvadratno) pokazuje nešto blago više i značajne pozitivne korelacije s neuroticizmom, iako su razlike između različitih načina modeliranja relativno male. Dobiveni rezultati podupiru ideju o većoj pobudljivosti vezanoj uz crtu neuroticizma. Iako su korelacije iznimno male, ne odstupaju od onih dobivenih u drugim istraživanjima, pogotovo jer je riječ o jednome mjerenju (Stemmler i Wacker, 2010). - This study aimed to examine interindividual differences in electrodermal responses to a sudden stimulus by using different methods of electrodermal reaction assessment. Modelling the electrodermal response as a simple difference of mean electrodermal level before and after stimulus occurrence was compared with approaches that model the electrodermal response curve over time. The association of differently modelled electrodermal reaction with questionnaire measures of personality traits was examined. Ninety-seven students, mostly females (60 %), with age ranging from 18 to 28 participated in this study. Each subject completed a brief measure of neuroticism and extraversion from the Big Five Inventory (BFI; John et al., 1991, 2008) and participated in one laboratory measurement of electrodermal activity during a period of 8 minutes in which a sudden stimulus was presented. Electrodermal activity was modelled in three ways: 1) as a difference in pre- and post-stimulus responses; 2) including linear effects of time; 3) including quadratic effects of time. The outcomes of differently modelled electrodermal responses were correlated with questionnaire measures of neuroticism and extraversion. The results showed that by taking into account the effects of time (both linear and quadratic) the actual electrodermal data can be fitted significantly better. Likewise, estimates of the electrodermal response that take into account the effects of time result in both higher average response levels and interindividual variability. The electrodermal reaction modelled in this way (linear and quadratic) shows a slightly higher and significant positive correlation with neuroticism when compared to simpler methods, although the differences between the different modelling methods are relatively small. The results obtained support the idea of greater excitability related to the neuroticism trait. excitability associated wit.

Life adversities and trauma as factors of addictive behaviors [Elektronička građa] : analysis of accumulation across the earliest life period / Alla Ataliieva, Bohdan Biron, Vsevolod Rozanov. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - Within this study 117 drug and alcohol addicts (97 males and 20 females) were compared with a matching group of healthy controls. All respondents were questioned regarding negative life events (NLE) that have happened to them during different periods of their life, in particular when they were 0-6, 7-14, 15-18 and 19 and more years old. The questionnaire consisted of 69 questions which covered such issues as “assault”, “divorce/separation”, “major financial problems”, “serious illness or injury”, “legal problems”, “loss of confidant”, “serious marital problems”, “being robbed”, “serious difficulties at work”, “serious housing problems” and “job loss”, etc. Events related to the personal network and early life period included death of a parent, loss of an individual in the network, alcohol and drug addiction of a parent, problems in relations with parents, separation from parents, being brought up by persons other than parents, housing problems, having very bad relations with a parent, etc. It was found that the life course of NLE accumulation in addicts is 3 times higher than in controls, the differences were statistically significant (p<0,001) in all life periods. In the hierarchical regression model which was used, accumulation of NLEs in the early childhood and young adulthood (after 19) have a bigger impact than periods of school years and ad-olescence. Analysis of NLEs in the earliest life period (0-6 years) in addicts showed that alcohol problems in parents and perceived feelings that parents do not love them and even torture them emotionally were much more frequent than in controls. Other strong associations were with being brought up by people other than parents and father’s addiction. Physical and sexual violence were not among the priorities and were not so strongly associated with addiction. - U ovom je istraživanju 117 ovisnika o drogama i alkoholu (97 muškaraca i 20 žena) uspoređeno sa skupinom zdravih ispitanika. Svi ispitanici ispitivani su o negativnim životnim događajima (engl. Negative Life Events – NLEs) koji su im se dogodili u različitim razdobljima života, posebno u dobi od 0 do 6, 7 do 14, 15 do 18 te 19 i više godina. Upitnik se sastojao od 69 pitanja koja su se odnosila na događaje kao što su „napad”, „razvod/razdvajanje”, „veliki financijski problemi”, „teške bolesti ili ozljede”, „pravni problemi”, „gubitak osobe od povjerenja”, „ozbiljni bračni problemi”, „pljačka”, „ozbiljne poteškoće na poslu”, „ozbiljni stambeni problemi”, „gubitak posla” itd. Događaji koji obuhvaćaju mrežu bliskih ljudi u ranom životnom razdoblju uključuju smrt roditelja, gubitak bliske osobe, ovisnost roditelja o alkoholu i o drogama, probleme u odnosima s roditeljima, odvojenost od roditelja, odgajanje od strane drugih osoba, stambene probleme, vrlo loše odnose s roditeljem itd. Utvrđeno je da je broj negativnih životnih događaja kod ovisnika tri puta veći nego kod skupine zdravih ispitanika – razlike su bile statistički značajne (p <0,001) u svim životnim razdobljima. U hijerarhijskom regresijskom modelu koji je primijenjen negativni životni događaji u ranom djetinjstvu i ranoj odrasloj dobi (nakon 19 godina) imaju veći utjecaj od negativnih događaja u školskoj dobi i adolescenciji. Analiza negativnih životnih događaja u najranijoj životnoj dobi (do šest godina) kod ovisnika je pokazala da su problemi roditelja s alkoholom i osjećaj da ih roditelji ne vole, pa čak i emocionalno muče bili mnogo češći nego kod skupine zdravih ispitanika. Druge jake asocijacije uočene su kod odgoja od strane drugih osoba. Tjelesno i seksualno nasilje nisu bili među prioritetima i nisu bili tako snažno povezani s ovisnošću.

Nadomjesna i potpomognuta komunikacija u bolnici - znanja, iskustva i stavovi medicinskih sestara [Elektronička građa] / Lada Perković, Anita Klarić, Mirna Kostović Srzentić. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Sažetak ; Abstract. - Nadomjesna i potpomognuta komunikacija (NPK) unaprjeđuje kvalitetu zdravstvene skrbi i zadovoljstvo pacijenata. U Hrvatskoj nedostaju istraživanja o primjeni NPK u bolnicama. Cilj ovog istraživanja je ispitati komunikaciju medicinskih sestara s pacijentima sa složenim komunikacijskim potrebama te njihovu upoznatost i stavove o NPK. U istraživanju su sudjelovale medicinske sestre (N=121) iz jedne od najvećih hrvatskih bolnica. Anketni upitnik sastojao se od pitanja o iskustvu sudionika s pacijentima sa složenim komunikacijskim potrebama, znanju, iskustvima i edukaciji o NPK. Stavovi prema implementaciji metode komunikacijskih ploča u bolnici ispitani su sa skalama tipa semantičkog diferencijala. Više od 50% sudionika u redovitim je kontaktima s pacijentima čija je komunikacija narušena zbog moždanog udara, kognitivnih i senzornih oštećenja, degenerativnih bolesti, utjecaja lijekova, jake boli ili jer ne govore hrvatski. Međutim, većina sudionika su slabo ili nikako upoznati sa značenjem pojma NPK te većina nema edukaciju iz tog područja. Većina medicinskih sestara koristi jednostavne metode NPK, ponajviše za komunikaciju o pacijentovim osnovnim potrebama, dok samo mali broj koristi NPK za komunikaciju u terapijske svrhe. Najveće prepreke korištenju NPK su nedostatak edukacije i resursa/pomagala. Sudionici imaju pozitivne stavove prema mogućem uvođenju komunikacijskih ploča u sestrinsku praksu, osobito stariji sudionici i oni s dužim stažem. Rezultati ukazuju na nedostatnu upoznatost i iskustvo medicinskih sestara s NPK te veliku potrebu za edukacijom. Preporučuje se uključivanje edukacije o NPK u obrazovne kurikulume na svim razinama sestrinskog obrazovanja. - Alternative and augmentative communication (AAC) improves quality of patient care and their satisfaction. There is a lack of research about AAC in Croatian hospitals. The objective of this study was to explore nurses’ communication with patients with complex communication needs, as well as their knowledge and attitudes regarding AAC. Subjects were 121 nurses from one of the largest Croatian hospitals. Survey questionnaire consisted of questions regarding the subjects’ experience with patients with communication difficulties, their knowledge, experience and education about AAC. Attitudes regarding the implementation of communication boards in hospital were assessed with semantic differential type scales. Over 50% of the respondents were in regular contact with patients whose communication was disrupted due to the stroke, cognitive and sensory impairment, degenerative diseases, medication, severe pain or because they don’t speak Croatian, but yet the majority of the respondents are vaguely or not at all acquainted with the meaning of AAC and had no education about it. Majority of the respondents use simple AAC methods for communication about patient basic needs and only a small number of the respondents use AAC for therapeutic communication. Lack of education and resources / aids are perceived as major barriers. The respondents have positive attitudes about the possible introduction of communication boards or cards into their practice, especially older and/or more experienced subjects. Results indicates that nurses are in a great need for education about AAC. Education about AAC should be included in health communication curriculum at all levels of the nursing education.

Norme za semantičke kategorije na hrvatskome jeziku [Elektronička građa] / Maja Kućar, Valnea Žauhar, Igor Bajšanski, Dražen Domijan, Tanja Gulan. - Graf. prikazi.
Prilog: Proporcije pojavljivanja i rang položaja odgovora unutar kategorija, str. 665-685. - Bibliografija: str. 662-664. - Sažetak ; Summary. - U ovome su radu prikazane norme za semantičke kategorije koje se pojavljuju u svakodnevnome jeziku. Popis 64 kategorije preuzet je iz normi na engleskome jeziku (Van Overschelde i sur., 2004), a dodane su još dvije kategorije. U istraživanju su sudjelovala 194 ispitanika (M = 38, Ž = 156), većinom studenti Sveučilišta u Rijeci (92.3 %). Zadatak ispitanika bio je navesti četiri tipična pripadnika za svaku kategoriju, a odgovori su bilježeni pomoću računala. U radu su prikazane mjere koje opisuju status kategorije, a to su ukupan broj navedenih entiteta (pripadnika kategorije), broj entiteta s frekvencijom jednakom ili većom od deset, broj visokofrekventnih entiteta čija je proporcija pojavljivanja jednaka ili veća od .80 te indeks konzistentnosti odgovaranja. Naveden je i rang kategorija prema indeksu konzistentnosti odgovaranja. Osim toga, za svaku su kategoriju prikazani odgovori s frekvencijom pojavljivanja jednakom ili većom od deset, a za svaki je navedeni entitet prikazana proporcija pojavljivanja, zatim proporcija pojavljivanja na prvome mjestu te prosječni rang položaja odgovora unutar pojedine kategorije. Izrađene norme za semantičke kategorije predstavljaju metodološki alat za ujednačavanje i sistematizaciju jezičnih podražaja koji će biti od koristi u budućim istraživanjima iz kognitivne psihologije, psiholingvistike i srodnih područja na hrvatskome jeziku. - In this paper, norms for semantic categories used in Croatian everyday language are presented. We used the list of 64 categories from the norms in English language (Van Overschelde et al., 2004), and 2 categories were added to the list. In the study participated 194 subjects (M = 38, F = 156), mainly students of the University of Rijeka (92.3 %). The participants had to list four typical exemplars for each presented category. Measures that describe the status of each category are shown: total number of entities, number of entities with a frequency higher or equal to ten, number of high-frequency entities whose proportion is equal to or higher than .80, and response consistency index. Categories were ranked according to the response consistency indexes. Furthermore, for each category, entities with a frequency higher or equal to ten are presented, and the proportion, proportion of appearing in the first place, and the mean rank of the position of the response are presented for each entity. Category norms are a methodological research tool that can be used for systematization of verbal stimuli in future research in the Croatian language in the area of cognitive psychology, psycholinguistics and related fields.

MATIĆ Bojić, Jelena
Odnos ličnosti i predrasuda [Elektronička građa] : teorijska osnova i pregled empirijskih nalaza / Jelena Matić Bojić. - Graf. prikazi.
Bibliografija: str. 723-727. - Sažetak ; Summary. - U posljednjih dvadesetak godina, uslijed teorijskoga i analitičkog napretka, obnovljen je interes za dispozicijska objašnjenja sklonosti predrasudama. Istraživačke su se tradicije ranoga dispozicijskoga i socijalnog pristupa kroz povijest istraživanja predrasuda izmjenjivale u popularnosti i suočavale s oštrom debatom o ulozi osobe nasuprot ulozi situacije u razvoju i održavanju predrasuda. Suvremena istraživačka praksa, međutim, inklinira k integraciji tih pristupa, a empirijski su utvrđene i određene komplementarnosti dispozicijskih i socijalnih perspektiva. Cilj je ovoga rada kontekstualizirati dispozicijski pristup istraživanju predrasuda, prikazati osnovne koncepte, teorijsko polazište i empirijske podatke o vezi ličnosti i predrasuda te skrenuti pažnju na otvorena pitanja i moguće pravce budućih istraživanja. Fokus je rada na vezi ličnosti i predrasuda prema različitim društvenim grupama koje se nerijetko prikazuju pod okriljem konstrukta generaliziranih predrasuda. Budući da je taj konstrukt od središnje važnosti za razumijevanje dispozicijskih doprinosa objašnjenju predrasuda, on se u radu pobliže predstavlja. Središnji dio rada sadrži prikaz Duckittove dvoprocesne kognitivno-motivacijske teorije ideologije i predrasuda koja je u podlozi odnosa ličnosti i predrasuda, pri čemu se poseban naglasak stavlja na pojašnjenje uloge ideoloških varijabli desne autoritarnosti i orijentacije na socijalnu dominaciju koje posreduju u tome odnosu. Slijedi prikaz empirijskih nalaza o povezanosti predrasuda i ličnosti prema petofaktorskoj konceptualizaciji te konceptualizaciji. Kao ključni antecedenti predrasuda izdvajaju se otvorenost prema iskustvu, ugodnost i poštenje – poniznost. U završnome se dijelu rada problematiziraju aktualni prijepori u području istraživanja povezanosti ličnosti i predrasuda: status ugodnosti kao prediktora predrasuda te konzistentnost dispozicijskih korelata generaliziranih predrasuda. - In the last twenty years, there has been a renewed interest in dispositional explanations of prejudice. The research traditions of early dispositional and social approaches have faced fierce debate on the role of person vs. situation in developing prejudice throughout the history of prejudice research. Contemporary research practice, however, inclines toward the integration of these approaches. Moreover, there have been empirically established complementarities of the two perspectives. This paper aims to contextualize the dispositional approach to prejudice, to present the basic concepts, theoretical basis and empirical data on the relationship between personality and prejudice, and to shed light onto open questions and future directions. It focuses on the association between personality and prejudice toward various social groups, often appearing under the 'generalized prejudice' construct. This construct is of vital importance for understanding the contributions of dispositional approach to prejudice. The central part of the paper contains the review of Duckitt's dual-process cognitive-motivational theory of ideology and prejudice that is at the base of personality-prejudice relation, with a special emphasis dedicated to the role of right-wing authoritarianism and social dominance orientation, ideological variables which mediate the personality-prejudice relationship. Further on, empirical findings on the association between prejudice and Big Five and HEXACO personality are presented. Openness to experience, agreeableness and honesty-humility stand out as key antecedents of prejudice. The concluding part discusses current disputes in the research on personality-prejudice relation: the status of agreeableness as a predictor of prejudice and the consistency of dispositional correlates of (generalized) prejudice.

Omjer širine i visine lica političara i uspjeh na političkim izborima [Elektronička građa] / Irena Pavela Banai, Benjamin Banai, Mladen Mavar. - Graf. prikazi.
Bibliografija: str. 601-606. - Sažetak ; Summary. - Prijašnja su istraživanja pokazala da prilikom glasovanja na političkim izborima birači uzimaju u obzir fizičke karakteristike političkih kandidata. Primjerice, birači češće glasaju za političare koje na temelju lica percipiraju kao kompetentnije. Također, kandidati koji izgledaju dominantnije i muževnije imaju veću prednost kod konzervativnijih birača. Budući da se omjer širine i visine lica pokazao prediktorom procjena muževnosti i dominantnosti, cilj je ovoga istraživanja bio ispitati doprinos navedenoga omjera u predviđanju ishoda stvarnih političkih izbora. U tu je svrhu korištena baza digitalnih fotografija lica političkih kandidata za Kongres (Senat i Zastupnički dom) i mjesto guvernera Sjedinjenih Američkih Država, a koji se mogu podijeliti u dvije kategorije ovisno o pripadnosti Demokratskoj, odnosno Republikanskoj stranci. Na temelju prikupljenih fotografija izračunani su omjeri širine i visine lica za ukupno 259 kandidata i 52 kandidatkinje. Nizom linearnih i binarnih regresijskih analiza, uz kontrolu spola kandidata, pripadnosti stranci, tipa izbora te vrste kandidature (reizbor ili prva kandidatura), nije utvrđeno da omjer širine i visine lica predviđa ishod izbora i proporciju osvojenih glasova. U pokušaju objašnjenja neočekivanih nalaza u obzir je uzeto nekoliko aspekata s ciljem pružanja smjernica za buduća istraživanja. - Previous studies have shown that during the election process voters rely on different physical characteristics of political candidates. For example, politicians who are perceived as more competent have greater electoral success. In addition, candidates who look more dominant and masculine are preferred among conservative voters. Since facial width-to-height ratio (fWHR) is assumed to be a predictor of perceived masculinity and dominance, this study aimed to investigate the contribution of fWHR in predicting the outcome of the real political elections. We used a digital database containing photographs of political candidates for the United States Senate (United States Congress and United States House of Representatives) and gubernatorial elections, representing Republican and Democratic Party. fWHR was calculated for the 259 male and 52 female candidates. Across several linear and binary regressions, with the control of the candidate’s sex, party affiliation, election type and candidacy type (incumbency or first candidacy), fWHR predicted neither the election outcome nor the vote share. Several methodological aspects have been discussed to explain these unexpected findings and to give guidance for future research.

On the development of emotional intelligence [Elektronička građa] : two-wave study on early adolescents / Ana Babić Čikeš, Vesna Buško. - Graf. prikazi.
Tema broja: Emocionalna inteligencija. - Bibliografija: str. 113-118. - Summary. - This study focuses on the developmental changes in emotional intelligence (EI) abilities during early adolescence. During class hours, 561 students in the first wave (Mage = 12.32, SDage = 1.22, 54.5% of boys) and 369 students in the second wave (M = 13.40; SD = 0.98, 52.3% of boys) completed Perception of Affective Content in Art Test, Analysis of Emotions Test, Emotion Management Test and rated their peers’ EI at two waves, 18 months apart. They also completed a Mill Hill Vocabulary Scale within the first wave. Students’ EI was also rated by their home room teacher and one teacher who completed Teacher Ratings of EI Questionnaire specifically designed for this study. Results showed that girls and older students scored higher on EI tests and peers’ ratings. Oldest students achieved the lowest scores on teacher ratings. The longitudinal analysis confirmed positive changes between the first and the second wave. Results of both the crosssectional and two waves analysis revealed significant effects of gender and general cognitive ability, measured with vocabulary test, on EI measures.

Osobine ličnosti učenika, strategije samoregulacije učenja i suočavanja sa školskim neuspjehom, dob i rod kao prediktori objektivnoga i subjektivnoga školskog uspjeha [Elektronička građa] / Anela Nikčević-Milković, Sanja Tatalović Vorkapić. - Graf. prilozi.
Bibliografija: str. 500-506. - Sažetak ; Summary. - Cijeli niz istraživanja potvrđuje povezanost između osobina ličnosti, samoregulacije učenja i školskoga postignuća, iako te povezanosti nisu jednostavne. Osobine ličnosti važni su prediktori objašnjenja samoregulacije učenja, a jedno i drugo važni su prediktori objašnjenja objektivnoga i subjektivnoga školskog uspjeha, odnosno zadovoljstva školom. Osnovni je cilj ovoga istraživanja bio ispitati u kojoj mjeri demografske karakteristike učenika (dob i rod), osobine ličnosti, (meta)kognitivne strategije učenja, strategije suočavanja sa školskim neuspjehom i strategije traženja socijalne podrške (kao prediktori) objašnjavaju objektivni i subjektivni školski uspjeh (kao kriterije). U istraživanju je sudjelovalo 457 učenika 6. i 8. razreda osnovne škole i 2. razreda srednje škole iz četiriju osnovnih i triju srednjih škola u Republici Hrvatskoj. Rezultati pokazuju da se s povećanjem dobi smanjuje objektivni školski uspjeh. Učenice imaju veći objektivni školski uspjeh, kao i savjesniji učenici te oni učenici koji manje koriste maladaptivne strategije površinskoga kognitivnog procesiranja informacija (što je i najznačajniji negativni prediktor objektivnoga školskog uspjeha). Navedeni set prediktora uspješno je objasnio 29 % objektivnoga školskog uspjeha kao kriterija. S povećanjem dobi učenika smanjuje se i subjektivni školski uspjeh. Učenici koji su viši na osobini Ugodnosti, koji manje koriste maladaptivne strategije zaštite emocija udaljavanjem prilikom suočavanja sa školskim neuspjehom, a više rabe adaptivne strategije traženja emocionalne i instrumentalne podrške od prijatelja, imaju veći subjektivni školski uspjeh. Navedeni set prediktora uspješno je objasnio 18 % subjektivnoga školskog uspjeha kao kriterija. - Series of studies have confirmed the significant correlation between personality traits, selfregulation of learning and academic achievement, although these relations are not simple. Personality traits are important predictors of self-regulation of learning, and both are significant predictors of the explanation of objective and subjective school achievement (school satisfaction). The main objective of this research was to examine the extent to which demographic characteristics of students (age and gender), personality traits, the (meta)cognitive strategies of self-regulation of learning, the coping strategies with school failure and the strategy of seeking social support (as predictors) explain objective and subjective school achievement (as criteria). Total of 457 students from 6th and 8th grade of elementary school and 2nd grade of high school from four elementary and three secondary schools in the Republic of Croatia participated in the study. The results show that objective school achievement decreases as students’ age increases. Female students have higher objective school achievement, as well as more conscientious students and those students who less rely on maladaptive strategies of surface cognitive information processing (which is also the most significant negative predictor of objective school success). The above set of predictors successfully explained 29 % of objective school achievement as a criterion. Subjective school achievement also decreases with increased age. Students who are higher on the Agreableness, who less rely on maladaptive strategies of Protection of emotions by moving away when facing school failure, and use more adaptive strategies Ask for emotional and instrumental support from friends, have greater subjective school success. The above set of predictors successfully explained 18 % of subjective school performance as a criterion.

Političko (ne)povjerenje kao odrednica glasanja i sklonosti protestnim oblicima političkog sudjelovanja [Elektronička građa] / Renata Franc, Marina Maglić, Ines Sučić. - Graf. prikazi.
Bilješke uz tekst. - Bibliografija: str. 400-405. - Sažetak ; Summary. - Polazeći od dvodimenzionanog razumijevanja povjerenja u političke institucije, u radu provjeravamo prediktivnost povjerenja u vladu i predstavničke institucije i povjerenja u provedbene institucije za objašnjenje glasanja te prosvjednog sudjelovanja, kao i moguću posredujuću ulogu zadovoljstva funkcioniranjem političkog sustava. Rad se temelji na hrvatskim podatcima petog vala Europskog istraživanja vrednota – EIV (European Values Study – EVS, 2017). Pojedinačne povezanosti dvaju oblika povjerenja i dvaju tipova sudjelovanja pokazuju da je izraženije povjerenje u vladu i predstavničke institucije povezano s češćim glasanjem te manjom sklonošću prosvjednom sudjelovanju, dok je povjerenje u provedbene institucije povezano samo s manjom sklonošću prosvjednom sudjelovanju. Ujedno, oba su oblika političkog povjerenja snažno međusobno povezana te praćena većim zadovoljstvom funkcioniranjem političkog sustava, a koje je u slaboj pozitivnoj vezi s glasanjem te u negativnoj sa sklonošću prosvjedima. Multivarijatnom analizom potvrđen je samo samostalan pozitivni doprinos povjerenja u vladu i predstavničke institucije za pojašnjenje glasanja. Rezultate raspravljamo u kontekstu visoke povezanosti dvaju oblika političkog povjerenja u hrvatskim uvjetima te dosadašnjih nalaza o odrednicama glasanja i prosvjednog sudjelovanja kao dvaju oblika političkog sudjelovanja. - Starting from a two-dimensional understanding of trust in political institutions, the paper examines trust in the government and representative institutions and trust in executive institutions as predictors of voting and protest participation, as well as the possible mediating role of satisfaction with the functioning of the political system. The paper is based on the Croatian data from the fifth wave of the European Values Study (EVS, 2017). Individual associations between the two forms of trust and the two types of participation indicate that greater trust in government and representative institutions is associated with more frequent voting and a lower propensity for protest participation. In contrast, trust in executive institutions is only associated with a lower propensity for protest participation. At the same time, both forms of political trust are strongly interconnected and accompanied with greater satisfaction with the functioning of the political system, which is weakly positively associated with voting and negatively associated with the propensity for protest participation. The multivariate analysis confirmed only the trust in government and representative institutions as a unique positive predictor of voting. The results are discussed in view of the high association between the two forms of political trust in the Croatian context, and the findings to date regarding the determinants of voting and protest participation as two forms of political participation.

Pouzdanost mjerenja u psihologiji [Elektronička građa] : razvoj metode, zaluđenost Cronbachovim alfa koeficijentom i preporuke za ispravnu procjenu pouzdanosti / Josip Novak.
Bibliografske bilješke uz tekst ; bibliografija: str. 448-456. - Sažetak ; Summary. - Svrha je ovoga preglednog rada uputiti na bogatu povijest koncepta pouzdanosti mjerenja i strjelovit napredak u procjeni pouzdanosti koji se dogodio od 1940-ih, što je rezultiralo velikim brojem pristupa procjeni pouzdanosti. Na početku je rada naveden kratak povijesni pregled nastanka koncepta pouzdanosti i metoda procjene pouzdanosti. Potom su opisani koeficijenti unutarnje konzistencije prateći njihov kronološki razvoj. Kritizirana je primjena Cronbachova α koeficijenta bez provjere potrebnih pretpostavki te su obrazložene česta pogrešna shvaćanja vezana uz Cronbachov α koeficijent. Navedene su pretpostavke potrebne za opravdanu primjenu α koeficijenta, pristranosti procjene u slučaju nezadovoljenosti potrebnih pretpostavki, ispravan način izvještavanja o pouzdanosti, kao i moguće primjene koeficijenta u svrhe različite od procjene pouzdanosti. Međutim, u praksi su pretpostavke za opravdanu primjenu α koeficijenta vrlo rijetko zadovoljene i često je opravdana primjena drugih koeficijenata, poput λ2, λ4, ρNDG ili ω, za kojeg se pokazalo da je u većini uvjeta najmanje pristran. Ponuđene su smjernice za primjenu navedenih koeficijenata. Najnoviji je pristup procjeni pouzdanosti strukturalnim modeliranjem, koje omogućava jednostavnu provjeru navedenih pretpostavki i u kombinaciji s ω i ωH koeficijentima rezultira vjerodostojnom procjenom pouzdanosti, a opravdan je u slučaju kompleksnih mjernih modela. Naposljetku, istaknuti su konceptualni problemi vezani uz procjenu pouzdanosti te su predložene smjernice za daljnja istraživanja pouzdanosti mjerenja. - The purpose of this review article is to indicate the abundant history of the concept of measurement reliability and steep improvement in reliability estimation since the 1940s, which produced a large number of approaches to its estimation. At the beginning of the article, a brief historical review of the emergence of the concept of measurement reliability together with methods of reliability estimation is given. Afterwards, different coefficients of internal consistency are described in chronological order. Application of Cronbach’s α coefficient without verifying necessary assumptions is criticized, and common misconceptions about α coefficient are elucidated. Necessary assumptions for use of Cronbach’s α coefficient, its biases in case of unfulfilled assumptions, best practice of reporting, and potential applications of the coefficient beside reliability estimation are outlined. However, necessary assumptions extremely rarely hold in practice and application of some other coefficients is often more appropriate, such as λ2, λ4, ρGLB or ω, the least biased one in most cases. Guidelines for use of mentioned coefficients are offered. The most recent approach to reliability estimation is by using structural equation modelling due to its ability to conveniently assess aforementioned assumptions and its synergy with ω and ωH coefficients, as well as its appropriateness in case of complex measurement models. Finally, conceptual issues on measurement reliability are discussed and guidelines for further research of measurement reliability are suggested.

Predictive processing of interoception, decision-making, and allostasis [Elektronička građa] : a computational framework and implications for emotional intelligence / Hideki Ohira. - Ilustr., graf. prikazi.
Tema broja: Emocionalna inteligencija. - Bibliografija: str. 14-16. - Summary. - Emotional intelligence is composed of a set of emotional abilities, including recognition of emotional states in the self and others, the use of emotions to guide thoughts and behaviours, and emotion regulation. Previous studies have demonstrated that emotional intelligence is associated with mental health, social problem solving, interpersonal relationship quality, and academic and job performance. Although emotional intelligence has received much interest both in basic research fields and applied and clinical fields, the mechanisms underlying the functions of emotional intelligence remain unclear. The aim of the present article was to consider the mechanisms of emotional intelligence using a computational approach. Recent theories of emotion in psychology and neuroscience have emphasized the importance of predictive processing. It has been proposed that the brain createsinternal models that can provide predictions for sensation and motor movement, and perception and behaviors emerge from Bayesian computations rooted in these predictions. This theoretical framework has been expanded to include interoceptive perception of the internal body to explain affect and decision-making as phenomena based on interoception. This perspective has implications for understanding issues of emotional intelligence.

Predictors of social physique anxiety among recreational bodybuilders [Elektronička građa] / Mirta Blažev, Divna Blažev, Anita Lauri Korajlija, Veronika Blažev. - Graf. prikazi.
Bibliografija: str. 520-523. - Summary ; Sažetak. - This study aimed to determine the contribution of gender, age, intensity of exercise, perfectionism, perfectionistic self-presentation and eating attitudes in the explanation dimensions of social physique anxiety (SPA) in a sample of 345 male and female gym exercisers. The results of this study indicate that the implemented model explains 21.3 % (p <.001) of the variance in Dissatisfaction with appearance and 48.4 % (p <.001) of the variance in Worry about appearance. Significant predictors of Dissatisfaction with appearance are intensity of exercise, discrepancy and eating attitudes, while significant predictors of Worry about appearance are gender, intensity of exercise, discrepancy, avoiding displays of imperfection and eating attitudes. In other words, recreational levels of exercise, negative perfectionism and negative attitudes towards food are strong predictors of social physique anxiety, while the tendency to hide our imperfections and female gender are only relevant when it comes to worry about appearance. - Cilj je istraživanja bio utvrditi koliko spol, dob, ozbiljnost vježbanja, perfekcionizam, perfekcionistička samoprezentacija te stavovi prema hranjenju doprinose objašnjenju dimenzija straha od negativne evaluacije izgleda na uzorku od 345 muških i ženskih sudionika koji vježbaju u teretani. Rezultati istraživanja pokazuju da testirani model objašnjava 21.3 % (p <.001) varijance Nezadovoljstva izgledom i 48.4 % (p <.001) varijance Brige o izgledu. Značajni su prediktori Nezadovoljstva izgledom ozbiljnost vježbanja u teretani te Diskrepancija i stavovi prema hranjenju, dok su značajni prediktori Brige o izgledu spol, ozbiljnost vježbanja u teretani, Diskrepancija, nepokazivanje nesavršenosti i stavovi prema hranjenju. Drugim riječima, rekreativne razine vježbanja, neadaptivni perfekcionizam i negativni stavovi prema hranjenju snažni su prediktori straha od negativne evaluacije izgleda, dok su sklonost izbjegavanju pokazivanja vlastite nesavršenosti i ženski spol relevantni samo za brigu o izgledu.

LONZA, Anamarija
Primjena mrežne analize u psihologijskim istraživanjima [Elektronička građa] / Anamarija Lonza. - Graf. prikazi.
Bibliografija: str. 579-584. - Sažetak ; Summary. - Mrežni pristup predstavlja novu paradigmu u proučavanju odnosa između psiholoških konstrukata i manifestnih varijabli. Prema tome pristupu varijable tvore autonomni dinamički sustav, a konstrukt se ne promatra kao njihov uzrok, već kao rezultat njihove kompleksne međusobne interakcije. Analitički se taj pristup zasniva na metodi mrežne analize koja modelira varijable kao čvorove povezane skupom bridova. Ovaj rad predstavlja svojevrsni pregled skupa postupaka u mrežnoj analizi, odnosno nudi njihovo pojašnjenje te njihovu praktičnu primjenu na dvama različitim setovima podataka. Prvi set podataka predstavlja rezultate na upitniku DASS-21 (N = 1016) i u okviru njega demonstrirani su procjena parametara mreže, izračun mjera centralnosti čvorova, identifikacija klastera u mreži te provjera stabilnosti parametara. Rezultati pokazuju da najveću centralnost imaju čestica depresivnosti Osjetio/la sam kao da se nemam čemu radovati, čestica anksioznosti Osjetio/la sam da sam blizu panici i čestica stresa Osjećao/la sam se jako nervozno. Čvorovi mreže očekivano su se grupirali u tri klastera koji sadržajno reprezentiraju Depresivnost, Anksioznost i Stres. Analize stabilnosti pokazale su ograničenu stabilnost bridova, dok je stabilnost centralnosti čvorova ovisila o korištenoj mjeri. U drugome istraživanju, koje sadrži podatke o stavovima adolescenata prema izgledu vlastitoga tijela, prikazan je Test usporedbe mreža usporedbom mreže adolescenata (n = 524) i adolescentica (n = 763). Rezultati pokazuju da se dvije mreže komponenata stava o izgledu vlastitoga tijela ne razlikuju supstancijalno. - The network approach represents a novel paradigm for exploring relations between psychological constructs and observable variables. According to this approach, variables form an autonomous dynamical system; the psychological construct is therefore not viewed as their common cause, but a result of their complex interactions. From an analytical point of view, this approach is based on network analysis — a set of procedures which models variables as nodes connected by a set of edges. This paper presents an overview of network analytical procedures. In other words, it offers a brief explanation of the methods, as well as their practical application in two separate datasets. The first dataset represents data on DASS-21 (N = 1016) and it serves to demonstrate network estimation, centrality measures calculation, community detection and network stability analyses. According to the results, the highest centrality was obtained for the depression item I felt that I had nothing to look forward to, anxiety item I felt I was close to panic, and stress item I felt that 1 was using a lot of nervous energy. As expected, nodes were grouped into three clusters, namely Depression, Anxiety and Stress. Stability analyses demonstrated limited stability of edge strength, while the stability of node centrality depended on the measure used. In the second dataset, which represents data on adolescents' attitudes towards one's body appearance, the Network Comparison Test was demonstrated by comparing male (n = 524) and female (n = 763) networks. Results showed that the two networks do not differ substantially.

Psihometrijska obilježja Youngova upitnika shema [Elektronička građa] : (YSQ-S3) / Irena Mišetić, Andreja Bubić, Vesna Antičević. - Graf. prikazi.
Bibliografija: str. 540-543. - Sažetak ; Summary. - Cilj je ovoga istraživanja bio ispitati neke psihometrijske karakteristike hrvatske verzije Youngova upitnika shema. Istraživanje je provedeno na kliničkome uzorku od 269 pacijenata liječenih od anksioznih poremećaja i poremećaja raspoloženja (Mdobi = 46.8, SDdobi = 10.5). Provedena je metoda glavnih komponenata uz ortogonalnu (Varimax) rotaciju. Rezultati provjere konstruktne valjanosti pokazali su da hrvatska verzija Youngova upitnika shema u većoj mjeri potvrđuje originalnu faktorsku strukturu (potvrđeno je 16 od 18 faktora kojima je objašnjeno 56.32 % ukupne varijance toga konstrukta). Cronbachov alfa koeficijent za cijeli upitnik iznosi .96, dok se vrijednosti koeficijenta pouzdanosti za pojedine sheme kreću u rasponu .71 do .93, uz iznimku sheme samokažnjavanje čija je pouzdanost tipa unutarnje konzistencije .49. Kako bismo provjerili konvergentnu valjanost upitnika, korišteni su Beckov inventar depresije – II (Beck i sur., 2011) i Ljestvica anksioznosti kao stanja i osobine ličnosti (Spielberger, 2000). Korelacije između rezultata na Youngovu upitniku shema i Beckovu inventaru depresije – II kretale su se između .12 i .62, a korelacije između rezultata na Youngovu upitniku shema i Ljestvici anksioznosti kao stanja i osobine ličnosti bile su između .23 i .50. Rezultati su pokazali da je hrvatska verzija Youngova upitnika shema mjerni instrument primjerene konstruktne i konvergentne valjanosti te zadovoljavajuće pouzdanosti tipa unutarnje konzistencije koji se može koristiti za procjenu ranih neprilagođenih shema na kliničkoj populaciji osoba koje se liječe od anksioznih i depresivnih poremećaja. - This study aimed to examine some of the psychometric characteristics of the Croatian version of the Young Schema Questionnaire to verify its construct validity and to compare these results with results of research in different populations. The study was conducted on a clinical sample consisting of 269 patients treated for anxiety disorders and mood disorders (Mage = 46.8, SDage = 10.5). Principal component analysis with orthogonal (Varimax) rotation was conducted. The results of examining construct validity showed that the Croatian version of Young's scheme questionnaire largely confirms the original factor structure (16 of the 18 factors that explain 56.32 % of the total variance of this construct). The Cronbach's alpha coefficient for the whole questionnaire is .96, while the reliability for the individual schemas range from .71 to .93 (the exception is the selfpunishment scheme whose internal consistency reliability is .49). To investigate the convergent validity of the questionnaire, we used Beck's Depression Inventory - II (Beck et al., 2011) and Anxiety Scale as state and trait (Spielberger, 2000). Correlations between scores on the Young Scheme Questionnaire and Beck’s Depression Inventory - II were between .12 and .62, and correlations between the scores on the Young Scheme Questionnaire and the Anxiety Scale as state and trait were between .23 and .50. The results showed that the Croatian version of the Young Schema Questionnaire is a measurement instrument with good construct and convergent validity as well as satisfactory internal consistency reliability, that can be used to measure early maladaptive schemas in the clinical population of people being treated for anxiety and depression.

The relationship between mindful parenting, cognitive parental awareness, and the subjective well-being of adolescents [Elektronička građa] / Maja Ljubetić, Ina Reić Ercegovac. - Graf. prikazi.
Bibliografija: str. 120-125. - Summary ; Sažetak. - The aim of this research is to explore the relationship between mindful parenting, cognitive parental awareness, and adolescents’ subjective well-being. The study included 101 families consisting of a mother, a father, and an adolescent child (N=303) aged 10 to 17, with a total of 69 female adolescents and 32 male adolescents. A general data questionnaire, mindful parenting questionnaire, and cognitive parental awareness questionnaire were administered to parents while adolescents completed a general data questionnaire, loneliness scale, life and family satisfaction scales, and general self-esteem scale. The results showed that male adolescents were more satisfied with life and had higher self-esteem than female adolescents. Measures of parenting were significantly related between mothers and fathers. The results also suggest that mindful parenting and cognitive parental awareness are significant correlates to the subjective well-being of adolescents when it comes to fathers, but not to mothers. - Cilj ovoga istraživanja bio je ispitati povezanost između usredotočene svjesnosti u roditeljstvu, kognitivne roditeljske svjesnosti i subjektivne dobrobiti adolescenata. U istraživanju je sudjelovala 101 obitelj (N=303) koju su činili majka, otac i dijete adolescentne dobi, u rasponu od 10 do 17 godina, i to 69 adolescentica i 32 adolescenta. Primijenjeni su upitnici općih podataka za adolescente i roditelje, upitnik usredotočene svjesnosti u roditeljstvu i upitnik kognitivne roditeljske svjesnosti, dok su adolescenti ispunili skale usamljenosti, zadovoljstva životom i obitelji te općeg samopoštovanja. Rezultati su pokazali da su adolescenti zadovoljniji životom i iskazuju više samopoštovanje u odnosu na adolescentice. Također, utvrđena je značajna povezanost između majki i očeva u većini mjera roditeljstva. Rezultati upućuju na zaključak da su usredotočena svjesnost u roditeljstvu i kognitivna roditeljska svjesnost značajni korelati subjektivne dobrobiti adolescenata kada je riječ o očevima, no ne i majkama.

The relationship between perceived emotional intelligence, work engagement, job satisfaction, and burnout in Italian school teachers [Elektronička građa] : an exploratory study / Antonella D'Amico, Alessandro Geraci, Chiara Tarantino. - Graf. prikazi.
Tema broja: Emocionalna inteligencija. - Bibliografija: str. 78-84. - Summary. - The study investigates the relationship between perceived emotional intelligence, burnout, work engagement, and job satisfaction in 238 Italian school teachers. The mean age was 50 years, ranged from 26 to 66 (SD = 9.16). The research protocol included a demographics data sheet, the Wong and Law Emotional Intelligence Scale (WLEIS; Wong & Law, 2002), the Copenhagen Burnout Inventory (CBI; Kristensen, Borritz, Villadsen, & Christensen, 2005), the Utrecht Work Engagement Scale (UWES; Schaufeli, Bakker, & Salanova, 2006), and the Organizational Satisfaction Scale (QSO; Cortese, 2001). Several international studies already demonstrated an association among these variables. Our results showed that perceived emotional intelligence positively correlates with work engagement and job satisfaction, and negatively correlates with burnout. Hierarchical regression analyses also point out that, among all the perceived emotional intelligence subdimensions, the use of emotion is the best predictor of the study variables, even when controlling for gender differences. These results suggest that emotional intelligence may have a protective role in preventing negative working experiences of teachers.

Relationship between self-reported symptoms of fatigue and cognitive performance [Elektronička građa] : switch cost as a sensitive indicator of fatigue / Marek Nieznański, Henryk Gasiul, Włodzimierz Strus, Michał Obidziński, Zdzisław Kobos, Tomasz Rowiński. - Graf. prikazi.
Bibliografija: str. 222-227. - Summary ; Sažetak. - In two correlational studies, we investigated the relationship between symptoms of mental fatigue connected with the ordinary daily activity of undergraduate students and the performance level in tasks engaging executive and attentional processes. We found that mild or moderate levels of fatigue are associated with only a few impairments in cognitive functioning, which suggests that the consequences of such a level of fatigue can be easily compensated by protection strategies adopted by participants. A notable exception was a significant positive correlation between the level of fatigue and higher accuracy switch cost in the Plus-minus task. Our participants also reported an increase in fatigue symptoms after performing several cognitive tasks and this change was larger for those who were more engaged in a sustained attention task. In a follow-up experiment, we investigated the effects of fatigue induced by the time on sustained attention task on switching task performance and reported symptoms of cognitive and executive fatigue. We confirmed that the level of accuracy switch cost is significantly higher in the participants who performed the sustained attention task than in the participants from the control group. We pointed out some possible practical implications of studies on the relationship between fatigue and cognition for such activities as driving a car. - U dvije je korelacijske studije kod studenata ispitana povezanost simptoma mentalnog zamora vezanog uz svakodnevne aktivnosti i izvedbe na zadacima koji uključuju izvršne procese i pažnju. Rezultati pokazuju da su blage ili umjerene razine zamora povezane s minimalno narušenom izvedbom, što sugerira da se posljedice takvih razina zamora mogu kompenzirati primjenom zaštitnih strategija. Iznimka je pritom značajna pozitivna povezanost razine zamora i veće cijene točnosti prebacivanja u zadatku plus-minus. Također, potvrđen je porast simptoma zamora nakon izvođenja nekoliko kognitivnih zadataka, a ta je promjena bila veća za ispitanike koji su se više angažirali na zadatku održavanja pažnje. U naknadnom je eksperimentu ispitan efekt zamora koji je induciran dužinom zadatka održavanja pažnje na izvedbu u zadatku prebacivanja i samoprocjenu simptoma kognitivnog i izvršnog zamora. Potvrđeno je da je cijena točnosti prebacivanja značajno veća kod ispitanika koji su izvodili zadatak održavanja pažnje nego kod ispitanika iz kontrolne skupine. U radu se upućuje na moguće praktične implikacije rezultata istraživanja o povezanosti mentalnog zamora i kognitivne izvedbe u aktivnostima poput vožnje automobila.

Rodna tipičnost visokoškolskih obrazovnih aspiracija tijekom srednje škole [Elektronička građa] : intenzifikacija, konvergencija ili stabilnost = Gender typicality of higher education aspirations in upper-secondary education : intensification, convergence or stability / Ivana Jugović, Teo Matković, Boris Jokić. - Graf. prikazi.
Tekst usporedno na hrv. i engl. jeziku. - Bibliografija: str. 280-283. - Sažetak ; Summary. - Cilj je rada bio ispitati dolazi li do intenzifikacije, konvergencije ili stabilnosti u rodnoj tipičnosti visokoškolskih obrazovnih aspiracija djevojaka i mladića tijekom vremena provedenoga u srednjoškolskom obrazovanju. U istraživanju na uzorku od 13 301 učenika/ca četverogodišnjih i petogodišnjih srednjoškolskih programa ispitana je i uloga srednjoškolskog programa te učeničkih interesa i školskog uspjeha u objašnjenju rodne tipičnosti njihovih visokoškolskih aspiracija. Rezultati upućuju na to da, iako postoje razlike između djevojaka i mladića u rodnoj tipičnosti obrazovnih aspiracija, te su razlike stabilne kroz vrijeme, čime nije potvrđena ni hipoteza rodne intenzifikacije, niti rodne konvergencije. Odabiri djevojaka i mladića kroz godine školovanja ne postaju ni više niti manje rodno stereotipni u odnosu na početak srednjoškolskog obrazovanja. Rezultati regresijskih modela pokazuju da se rodna tipičnost visokoškolskih aspiracija razlikuje s obzirom na strukovno područje/gimnazijski program, i to u očekivanom smjeru: učenici i učenice tipično muških programa aspiriraju tipično muškim studijima i obratno. Školski uspjeh i interesi također su pridonijeli objašnjenju rodne tipičnosti visokoškolskih aspiracija. Uspjeh iz hrvatskog jezika kao i interesi za jezično i biomedicinsko područje predviđaju snažniju aspiraciju tipično ženskim studijima, dok uspjeh iz matematike i engleskog jezika te interesi za tehničko i informatičko područje pridonose aspiraciji tipično muškom studiju. Nalazi ovog istraživanja ukazuju na to da, uz utjecaj rodno obilježenih obrazovnih interesa i postignuća, diferenciranost srednjoškolskog obrazovanja može utjecati na rodno stereotipne obrazovne aspiracije. - The aim of the paper was to examine intensification, convergence, or stability in the gender typicality of girls' and boys' higher education aspirations during the time spent in secondary education. The study, conducted on a sample of 13,301 pupils of four- and five-year secondary education programmes, examined the roles of the secondary education programme, pupils' interests, and school success in explaining the gender typicality of their higher education aspirations. The results suggest that, although there are differences between girls and boys in the gender typicality of their educational aspirations, these differences are stable over time, whereby neither the gender intensification nor the gender convergence hypotheses were confirmed. The girls' and boys' choices become neither more, nor less gender-stereotypical, compared to the start of secondary education. The results of regression models show that the gender typicality of higher education aspirations differs with regard to vocational domain/grammar school programme: pupils in typically male programmes aspire towards typically male higher education programmes and vice versa. School success and interests have also contributed to the explanation of the gender typicality of higher education aspirations. Success in the Croatian Language and interest in linguistic and biomedical domains predict a stronger aspiration towards typically female higher education programmes, while success in Mathematics and the English Language, and interest in technical and ICT domains contribute to the aspiration towards typically male higher education programmes. The findings of this study suggest that, along with the influence of gendered educational interests and achievements, the differentiation of secondary education can influence gender-stereotypical educational aspirations.

Sense of identity and self-control [Elektronička građa] : the mediating role of goal characteristics / Aleksandra Pilarska. - Graf. prikazi.
Bilješka uz tekst. - Bibliografija: str. 305-309. - Summary ; Sažetak. - This study addressed the role of a sense of personal identity as a self-regulatory mechanism that facilitates congruence and coherence of goals that people set for themselves and thereby enhances their capacity to exert self-control. A total of 489 young adults completed a packet of questionnaires that assessed basic dimensions of sense of identity, congruence and coherence of goals, and self-control capacity. Direct and indirect paths of a sense of identity on self-control were examined using structural equation modelling. The proposed model was, for the most part, supported by data. It should be noted, however, that the mediation effects were fairly small, and the sense of identity had a direct predictive effect on self-control over and above congruence and coherence of goals. - Ovo istraživanje ispituje osjećaj osobnog identiteta kao samoregulacijskog mehanizma, koji olakšava podudarnost i smislenost ciljeva koje si osoba postavlja, i tako povećava njihovu sposobnost samokontrole. U istraživanju je sudjelovalo 489 mlađih odraslih osoba, koje su ispunile niz upitnika za procjenu osnovnih dimenzija osjećaja identiteta, kongruencije i koherentnosti ciljeva te kapaciteta za samokontrolu. Strukturalnim modeliranjem provjerene su izravne i neizravne veze osjećaja identiteta na samokontrolu. Dobiveni rezultati uglavnom potvrđuju predloženi model. Potrebno je naglasiti da su medijacijski efekti prilično niski, a osjećaj identiteta imao je izravan prediktivni učinak na samokontrolu, nakon kontrole kongruencije i koherentnosti ciljeva.

Učinkovitost tehnika usredotočene svjesnosti i virtualne realnosti u smanjenju stresa te uloga osobine usredotočene svjesnosti i anksioznosti [Elektronička građa] / Barbara Žuro. - Graf. prikazi.
Bibliografija: str. 702-706. - Sažetak ; Summary. - U posljednje vrijeme raste popularnost usredotočene svjesnosti i virtualne realnosti u kontekstu nošenja sa stresom. Usprkos tomu nema dovoljno istraživanja koja su uspoređivala te tehnike i uzimala u obzir osobine ličnosti. Cilj je ovoga istraživanja bio ispitati učinkovitost tehnike usredotočene svjesnosti i virtualne realnosti u neposrednome ublažavanju stresa te ispitati učinkovitost tehnika ovisno o individualnim razlikama u osobinama anksioznosti i usredotočene svjesnosti. Istraživanje je provedeno na 122 sudionika. Za izazivanje uznemirenosti korištena je oprema virtualne realnosti i animacija visine. U svrhu opuštanja korištena je tehnologija virtualne realnosti i animacija prirode te snimka usredotočene svjesnosti, a pratile su se subjektivne i fiziološke mjere uznemirenosti (elektrodermalna aktivnost). Za prikupljanje podataka o osobini usredotočene svjesnosti korišten je Petfaktorski skraćeni upitnik usredotočene svjesnosti, dok je za anksioznost korištena skala anksioznosti u Upitniku tendencija izbjegavanja i približavanja. Dobiveni rezultati pokazali su kako su sudionici procjenjivali nižu uznemirenost nakon izlaganja animaciji prirode i snimci usredotočene svjesnosti u odnosu na kontrolnu skupinu, dok fiziološke mjere nisu pratile takve rezultate. Nadalje, uz primjenu snimke najviše su se opustili visoko anksiozni i nisko usredotočeno svjesni pojedinci, dok u primjeni animacije prirode te osobine nisu igrale značajnu ulogu. Provedeno istraživanje ukazuje na mogućnost korištenja kratkih tehnika usredotočene svjesnosti i virtualne realnosti pri nošenju sa stresom te na važnost osobina ličnosti pri odabiru tehnike. - Mindfulness and virtual reality (VR) have recently been growing popular as stress–coping strategies. Despite that, there is not enough research that compared these techniques or has taken personality traits into account. This study aimed to examine the effectiveness of mindfulness and virtual reality techniques for immediate stress–relief and to examine the efficacy of techniques depending on individual differences in trait anxiety and dispositional mindfulness. The study was conducted on 122 participants. One VR animation was used to induce fear of height in participants, while VR nature animation and mindfulness audiotape were used to relax participants. Subjective and physiological indices of anxiety were measured through electrodermal activity. Five–Facet Mindfulness Questionnaire and Questionnaire of Approach and Avoidance Motivation were used to collect information about dispositional mindfulness and trait anxiety. Results suggest that the participants estimated that they were significantly more relaxed after the nature animation and the mindfulness audiotape compared to the control group, although the physiological measures did not follow these results. Furthermore, mindfulness audiotape was most effective in highly anxious and low mindfulness individuals, while in the case of nature animation these dispositions did not play a significant role. This study indicates the possibility to use short mindfulness and virtual reality techniques in stress–reduction as well as the importance of personality traits in their effectiveness.

Validacija prijevoda upitnika SIPP-118 i kratke verzije upitnika PID-5 [Elektronička građa] / Tamara Gazdek, Katarina Klasić, Andrea Žulj, Silvija Ručević, Dino Krupić. - Graf. prikazi.
Bibliografija: str. 286-289. - Sažetak ; Summary. - Brojna istraživanja upućuju na važnost osobina ličnosti u predikciji različitih oblika rizičnog ponašanja kod adolescenata. U proteklih je nekoliko godina razvijen niz upitnika ličnosti koji su se pokazali uspješnim u predikciji rizičnog ponašanja. Većina tih upitnika nije prevedna na hrvatskom jeziku. Cilj je ovog istraživanja prikazati hrvatske prijevode Upitnika simptoma poremećaja ličnosti (SIPP-118) te kratke verzije Inventara ličnosti za DSM-5 (PID-5). Za procjenu konvergentne valjanosti upitnika PID-5 korištena je Dimenzionalna procjena osobina ličnosti (DiPOL), dok se Samoiskaz rizičnog i delinkventnog ponašanja mladih (SRDP) koristio za ispitivanje prediktivne valjanosti upitnika PID-5 i SIPP-118. Istraživanje je provedeno na 497 učenika gimnazije i strukovnih škola iz Osijeka, Belog Manastira, Đakova i Donjeg Miholjca. Rezultati konfirmatorne faktorske strukture upitnika SIPP-118 nisu potvrdili očekivanu faktorsku strukturu. Petofaktorska struktura upitnika PID-5 pokazala se najboljim modelom, no skale su međusobno suviše povezane što umanjuje divergentnu valjanost upitnika. Rezultati pokazuju kako su osobine ličnosti i indeks funkcioniranja ličnosti umjereno povezani s tendencijom rizičnog ponašanja. Hijerarhijska regresijska analiza pokazala je da se veći udio varijance u rizičnom ponašanju može objasniti upitnikom DiPOL u odnosu na PID-5. S obzirom na rezultate istraživanja savjetujemo oprez pri korištenju prevedenih upitnika. - Vast research indicates the importance of personality traits in predicting different types of risk behaviour in adolescents. In the last couple of years, several personality questionnaires have been successful in predicting risk behaviour in adolescents. The majority of these questionnaires have not been adapted in the Croatian language. The goal of this survey is to show Croatian translation of the Severity Indices of Personality Problems (SIPP-118) and the short version of the Personality Inventory for DSM-5 (PID-5). Dimensional Assessment of Personality Questionnaire (DAPQ) has been used to assess the convergent validity of PID-5 questionnaire, while Self-reported Delinquency and Risk Behaviours Questionnaire (SRDP) has been used for the assessment of the predictive validity of PID-5 and SIPP-118. The survey was conducted on 497 high school and vocational students in Osijek, Beli Manastir, Đakovo and Donji Miholjac. The results of the confirmatory factor structure of SIPP-118 questionnaire did not confirm the anticipated factor structure. Five-factor structure PID-5 has been declared as the best model, but the scales are highly interrelated, which diminishes the divergent validity of the questionnaire. The results show that personality traits and personality functioning scales are moderately related to the tendency to risk and socially unacceptable behaviour. The hierarchical regression analysis has shown that a larger part of the variance in risk behaviour can be explained using DAPQ questionnaire than using PID-5. Considering the results of this survey, caution is advised in using translated questionnaires.

ROKVIĆ, Nikola
Validation of the Serbian translation of the Disgust Propensity and Sensitivity Scale (DPSS) [Elektronička građa] / Nikola Rokvić. - Graf. prikazi.
Bibliografija: str. 643-646. - Summary ; Sažetak. - Disgust represents a feeling of revulsion and is manifested as a response to adverse stimuli and indicates a motivation to withdraw from the stimulus. Several attempts were made to measure disgust, the earliest being the Disgust Sensitivity Scale (Haidt et al., 1994) that relied on responses to disgust elicitors, and the Disgust Propensity and Sensitivity Scale (DPSS, Cavanagh & Davey, 2000) that focused on the feeling itself, not on the strength of the reaction to specific disgust elicitors. There are two proposed models of the DPSS, one with two subscales, disgust propensity (DP) and disgust sensitivity (DS), and the other with three subscales where the self-focused/ruminative disgust (SFR) split from DS. This study aimed to validate the Serbian translation of the scale. We used two samples, a student sample (N = 437) and a social network user sample (N = 344). We used confirmatory factor analysis in both samples and the yielded results have shown that the three-factor solution is superior. The internal consistency of the subscales was marginally acceptable, while SFR subscale alpha value lagged in the social network user sample. Significant gender differences in subscale values were detected as expected, adding to the scale validity. Also, DP and DS registered a weak positive correlation with trait Neuroticism, negative affect, stress, depression, and anxiety. These results will further our claims that our translation of the DPSS is valid. In conclusion, we believe that the Serbian translation of the 12 item DPSS scale is viable for use in future research on this subject. - Gađenje predstavlja osjećaj odbojnosti koji se pojavljuje kao odgovor na neugodne podražaje te je indikator motivacije izbjegavanja podražaja. Nekoliko je pokušaja mjerenja gađenja, a prve su razvijene skale Skala osjetljivosti na gađenje (Haidt i sur., 1994), koja se temelji na odgovorima na izazivače gađenja, i Skala sklonosti gađenju i osjetljivosti na gađenje (DPSS, Cavanagh i Davey, 2000), koja se više usmjerava na sam osjećaj gađenja, a manje na jačinu reakcije na specifične izazivače gađenja. Dva su predložena modela skale DPSS. Prema jednome modelu DPSS ima dvije podljestvice, sklonost gađenju (DP) i osjetljivost na gađenje (DS), dok se prema drugome modelu skala sastoji od triju podljestvica, odnosno skala osjetljivosti na gađenje sadrži još i samofokusirano/ruminirajuće gađenje (SFR). Cilj je provedenoga istraživanja bio validirati srpsku verziju skale DPSS. Istraživanje je provedeno na dvama uzorcima: na uzorku studenata (N = 437) i na uzorku prikupljenome putem društvenih mreža (N = 344). Na obama su uzorcima rezultati konfirmatorne faktorske analize pokazali bolje indekse pristajanja trofaktorskoga rješenja. Pouzdanost tipa unutarnje konzistencije bila je granično prihvatljiva, pri čemu je bila niža za podljestvicu SFR na uzorku studenata. Dobivene spolne razlike u skladu su s postavljenim hipotezama. Također, podljestvice sklonosti gađenju i osjetljivosti na gađenje bile su u niskim pozitivnim korelacijama s Neuroticizmom, negativnim afektom, stresom, depresivnošću i anksioznošću, što ide u prilog valjanosti skale. Zaključno, smatramo da je srpska verzija Skale sklonosti gađenju i osjetljivosti na gađenje od 12 čestica primjerena za korištenje u budućim istraživanjima te teme.

The Vocabulary of Emotions Test (VET) [Elektronička građa] : psychometric properties of the Serbian version / Ana Altaras Dimitrijević, Zorana Jolić Marjanović, Jelena Starčević. - Graf. prikazi.
Tema broja: Emocionalna inteligencija. - Bibliografija: str. 147-150. - Summary. - Considering the necessity to broaden the range of valid emotional intelligence (EI) measures, this study further examined the psychometric properties of the Vocabulary of Emotions Test (VET; Takšić, Harambašić, & Velemir, 2003). Participants were 333 university students (75.4% female) from Serbia, 245 studying education sciences or humanities, and 88 pursuing natural/technical sciences. All were administered the Serbian version of the VET and two standard tests of verbal intelligence (VI) and asked to report their average grade. The VET had good internal consistency (α = .83) and correlated positively with both measures of VI (r = .37 and .45), as with participants’ grades (r = .20). Significant group differences emerged on the VET, but not the two VI tests, with female participants and the Education Sciences/Humanities group scoring higher than their respective counterparts. A hierarchical regression analysis with VI (Step 1) and VET scores (Step 2) as predictors, and grades as the criterion, yielded a significant model (R 2 = .04) with emotional vocabulary explaining additional variance over VI (ΔR 2 = .02) and surfacing as the only independent predictor (β = .18) of academic achievement. Further analyses showed emotional vocabulary to incrementally predict achievement in education sciences and humanities (ΔR 2 = .03, β = .19), but not in natural/technical sciences, in which context neither VI nor emotional vocabulary were statistically significant predictors of students’ grades. The current results are interpreted as promising evidence on the reliability and validity of the Serbian VET, encouraging further use of this instrument in EI research.

Ljudska priroda i kontekst napretka [Elektronička građa] / Jelena Đurić.
Tema broja: Ljudska priroda. - Bibliografske bilješke uz tekst. - Sažetak ; Abstract. - Namjera je pokazati kako značenje ‘ljudske prirode’ proizlazi iz pogleda na svijet kakav u kontekstu napretka modernizacije vodi obezvrjeđivanju značenja pojma ljudsko. Ukazuje se na potrebu za takvom rekonceptualizacijom ljudske prirode kakva bi povezala globalne procese i onto-epistemo-etičke aspekte općeg pogleda na svijet. Ti bi aspekti predstavljali samorazumijevanje suvremene kulture. Prepreka je tom cilju aporetična struktura mišljenja, čiji se modernizacijski kontekst napretka temelji na odvajanju prirode i kulture. Odvajanjem se uspostavlja (ne)mogućnost odgovora na pitanje o tome je li kultura, kao izraz ljudske prirode, dio prirode ili je priroda, kao proizvod ljudske spoznaje, dio kulture. Umjesto nastojanja posthumanizma da tu nedoumicu riješi ukidanjem pojma ljudsko, što ne donosi rješenje ni ekološke ni drugih tipova krize, potrebno je redefinirati pojam ljudska priroda. - I intend to show in what way the meaning of the concept of human nature emerges from the worldview that, taken within the context of modernization, leads to the devaluation of the meaning of human. Hence the need to re-conceptualize human nature emerges in such a way that the concept of human nature is necessary intertwined with the global processes and onto-epistemo-ethical aspects of the general worldview that designate the (self)understanding of contemporary culture. The aporetic structure of thinking poses a barrier to this goal. Its context of modern progress is based on the separation of nature and culture. The separation establishes an (im)possibility of answering the question whether the culture, as an expression of human nature, is a part of nature or the nature is, as a product of human comprehension, a part of culture. Instead of the posthuman strive to resolve this dilemma by abolishing the concept of human, which resolves neither ecological nor other types of crisis, the concept of human nature needs to be redefined.

Ljudska priroda ili ljudske prirode [Elektronička građa] / Predrag Finci.
Tema broja: Ljudska priroda. - Bibliografske bilješke uz tekst. - Sažetak ; Abstract. - Može li ljudska priroda biti definirana? Autor se zalaže za opisivanje ljudske prirode, u čemu vidi mogućnost ukazivanja na njena bitna svojstva i svu različitost, ali i istost. Već samo postavljanje pitanja o ljudskoj prirodi govori o nužnosti filozofskog promišljanja svega što pripada i može pripadati ljudskom biću. Zato je pitanje o ljudskoj prirodi trajno otvoreno pitanje. - Can human nature be defined? The author advocates for describing the human nature, wherein he sees the possibility of pointing out its essential traits, not only the differences but also the sameness. The very question of human nature speaks about the necessity of philosophical reflection on all things human. Thus, the question regarding human nature is perpetual and open.

Ljudska priroda kod Machiavellija [Elektronička građa] : antropološki pesimizam kao podloga političkog "realizma" / Nino Raspudić.
Tema broja: Ljudska priroda. - Bibliografske bilješke uz tekst. - Sažetak ; Abstract. - O poimanju ljudske prirode u Machiavellijevu djelu možemo govoriti na dvije razine. Prva je razina njegov temeljni antropološki pesimizam. Polazna je točka Machiavellijeve političke filozofije da su ljudi po prirodi skloni zlu, što, kako navodi u Raspravama o prvoj dekadi Tita Livija, kao početnu pretpostavku mora uzeti i svaki zakonodavac. Na drugoj razini, narav je pojedinoga čovjeka po njemu bitno nepromjenjiva pa kada se ona slaže s vremenima, on uspijeva (primjer pape Julija II.), a kada je u neskladu s onim što zahtijeva kontekst, neuspjeh je neizbježan. Na nizu primjera iz Machiavellijevih djela pokazuje se da je njegov pesimistički uvid u ljudsku prirodu temelj na kojem se gradi cijela njegova politička teorija. Zlu i sebičnosti sklona ljudska priroda objašnjenje je za stvaranja zajednice, zakona i državnih institucija, ali i dinamike koja dovodi do njihovog kvarenja i propasti. - The concept of human nature in Machiavelli’s work can be discussed on two levels. The first level regards its fundamental anthropological pessimism. The starting points of Machiavelli’s political philosophy is that people are inclined by nature to be evil, which, as quoted in The Discourses on Livy, must be taken as a starting assumption by every legislator. On the second level, the nature of a particular man is essentially unchangeable, and thus when it agrees with the times, he succeeds (Pope Julius II being an example), and when a man is in contradiction with what is required by the context, failure is inevitable. Many examples from Machiavelli’s work show that his pessimistic insight into human nature is the foundation upon which his entire political theory is built. The human nature, prone to evil and selfishness, is the explanation for the creation of communities, laws and state institutions, but also for the dynamics that lead to their decay and destruction.

Moralna odgovornost i znanstvena slika svijeta [Elektronička građa] / Jelena Mijić.
Tema broja: Ljudska priroda. - Bibliografske bilješke uz tekst. - Sažetak ; Abstract. - Predmet su rada rasprave o odnosu determinizma i slobode volje (tj. problem kompatibilnosti), odnosno implikacije koje imaju po moralnu odgovornost. Problemu se pristupa iz naturalističke perspektive iako se ne nudi odgovor na pitanje istine kauzalnog determinizma. Međutim, s ciljem da se ispita perspektiva za moralnu odgovornost, pretpostavlja se da je kauzalni determinizam potkrijepljen znanošću. Razmatra se pojam kauzalnog determinizma, a potom se ispituju izazovi koje argument konzekvenci postavlja pred slobodu volje shvaćenu kao mogućnost da se učini drugačije. Cilj je rada pokazati da su u osnovi svakodnevne upotrebe pojma moralne odgovornosti slabiji uvjeti od slobode shvaćene kao mogućnosti da se učini drugačije. Na tim temeljima branimo zaključak da je moralna odgovornost kompatibilna s kauzalnim determinizmom. - This paper deals with the discussions concerning the relationship between determinism and free will (i.e. the Problem of Compatibility), and correspondingly, with the implications for moral responsibility. It approaches the problem from the naturalistic perspective, albeit it does not answer the issue of the truth of causal determinism. For the sake of exploring the prospects for moral responsibility, the paper assumes causal determinism is scientifically warranted. Starting from the concept of causal determinism, the paper examines the challenges for the concept of free will as an ability to act otherwise, invoked by the Consequence Argument. The goal is to demonstrate that requirements for the ordinary moral responsibility conception are weaker than freedom as the ability to act otherwise. On these grounds, it is concluded that moral responsibility and causal determinism are compatible.

Pojam čovjeka kao socijalno konstituiranog sebstva u Taylorovoj teoriji morala [Elektronička građa] / Hasnija Ilazi, Ardian Gola.
Tema broja: Ljudska priroda. - Bibliografske bilješke uz tekst. - Sažetak ; Abstract. - Razumijevanje čovjeka u Taylorovoj teoriji modernog društva uključuje u sebe vanjske komponente koje ga određuju – moralni okviri i društvena zajednica – te unutarnje komponente – kapacitete koji mu omogućavaju da se orijentira prema najvišim vrednotama, među kojima je najvažnija komponenta snažnog vrednovanja. Čovjek shvaćen kao sebstvo, osoba, subjekt ili identitet zasjenjuje, međutim, svoju multidimenzionalnost upućenošću na ekskluzivnost dimenzije moralnog dobra kao osnove čovjekova samovrednovanja. Rad obrađuje Taylorovu moralnu ontologiju, odnos sebstva i dobra te zasnovanost kreiranja modernog identiteta kao sinonima modernog čovjeka, na njegovom pozicioniranju u odnosu na najviše moralne vrednote. - Understanding the notion of human being in Taylor’s theory of modern society includes the understanding of external components that define it – a moral framework and a social community – and the understanding of internal components – the capacities, mainly the component of the strong evaluation, that enable it to be oriented towards the highest values. A human being understood as a self, a person, a subject, an identity, overshadows, however, their multidimensionality through the exclusivity of the dimension of moral good as the main reference to their self-evaluation. The paper elaborates Taylor’s moral ontology, the relationship between the self and the good, and the foundation for the creation a modern identity as the synonym for a modern human being in their positioning related to the highest moral values.

U mrežama normi [Elektronička građa] : Brandomovo razumijevanje racionalnosti / Kenan Šljivo.
Bibliografija: 12 jed. - Sažetak ; Abstract. - U ovom se radu analizira koncepcija racionalnosti koju u svom filozofskom učenju razvija Robert Brandom. Radi se o analizi Brandomova pragmatički orijentiranog diskursa koji se odnosi na pitanje racionalnosti iz perspektive čovjekovih jezičnih praksi, gdje se tek u susretu s drugim pripadnicima određene jezične zajednice manifestiraju oni aspekti ljudske prirode koje možemo označiti terminom racionalnost. Ono što čini središnji dio ovog rada odnosi se na Brandomov normativni idiom koji on postulira kao onaj koji je eksplanatorno najpodobniji za razumijevanje jezičnih praksi i na njima zasnovane ideje racionalnosti. - The paper analyses the concept of rationality as developed in the philosophical considerations of Robert Brandom. It is the analysis of Brandom's pragmatically-oriented discourse concerning the issue of rationality from the perspective of human being's linguistic practices, where only upon meeting the other members of specific linguistic community the aspects of human nature we may characterise by the term rationality are manifested. The central part of this paper treats Brandom's normative idiom that he postulates as explanatorily most suitable for understanding the linguistic practices and the idea of rationality based upon them.

JAKOVLJEVIĆ, Dragan
Za etiku kontinuuma prirode i čovjeka [Elektronička građa] : k jednom umjerenom utopijskom projektu za naše vrijeme, uz ishođenje od arhaičkog pojma ethos / Dragan Jakovljević.
Bilješke uz tekst. - Tema broja: Ljudska priroda. - Bibliografske bilješke uz tekst ; bibliografija: 16 jed. - Sažetak ; Zusammenfassung. - U ovom se članku sagledava pitanje odnosa čovjeka i prirode, polazeći od drevne nereflektirane upotrebe izraza ethos u smislu naviknutog mjesta življenja koje od strane njega nastanjujućih živih bića biva u određenoj mjeri (su)oblikovano. To se polazište dalje razrađuje kroz pojmove obitavalište i zavičaj (Milan Kangrga), odnosno zavičajni svijet i domovina (Bernhard Waldenfels). Drevni pojam ethos ne može zamijeniti odgovarajući moderni pojam, ali ipak može biti shvaćen kao njegova upotpunjavajuća primjesa smisla. Ona pokazuje neočekivanu aktualnost, s obzirom na suvremenu problematiku ekologije i biodiverziteta. Pritom se, prije svega, otvara pitanje o tome koje načine nastanjivanja i kultiviranja tla svakidašnjeg obitavališta treba preferirati, a koje izostaviti. Kao imperativ autor ističe neophodnost jednog obzirnog odnošenja prema drugim živućim bićima s kojima dijelimo planetarno obitavalište, ali i prema vegetaciji i prirodnom okruženju, uz poštovanje prema drugim, ne-ljudskim oblicima života i njihovoj dobrobiti. - In diesem Aufsatz wird betrachtet die Frage des Verhältnisses zwischen Natur und Menschen ausgehend vom alten unreflektierten Gebrauch des Ausdrucks Ethos im Sinne des gewöhnten Lebensortes, das von den es bewohnenden Lebewesen in bestimmten Ausmasse (mit-)gestaltet wird. Diese Ausgangsposition wird weiter ausgearbeitet durch Begriffe des Heimortes (Kangrga) bzw. der Heimwelt und Heimat (Waldenfels). Verfasser vertritt die Auffassung, wonach dieser überlieferter Ethos-begriff den entsprechenden modernen Begriff nicht zu ersetzen vermag, er kann aber immerhin als seine zusätzliche Sinnbeilage verstanden werden. Die Letztere zeigt vielmehr eine unerwartete Aktualität mit Rücksicht auf die gegenwärtige Problematik der Ökologie sowie Biodiversität. Hierbei wird vor allem die Frage geöffnet, welche Arten des Bewohnens als auch des Bodenkultivierens des jeweiligen Wohnortes sollen vorgezogen, und welche dagegen unterlassen werden. Als ein Imperativ hebt Verfasser die Notwendigkeit hervor eines umsichtigen Beziehens zu den anderen Lebewesen, zur Vegetation und natürlichen Umwelt mit denen wir das planetare Wohnort teilen, begleitet mit dem Respekt zur anderen, nicht-menschlichen Lebensformen sowie zu ihrem Wohlbefinden.

"Od zemlje, zemljan" [Elektronička građa] : konstitucija čovjeka u Post 1–2 u svjetlu sumersko-babilonskih tradicija / Miljenka Grgić.
Bibliografske bilješke uz tekst. - Sažetak ; Summary. - Studija istražuje konstituciju čovjeka u Post 1–2, proučavajući važnije tekstove o stvaranju čovjeka u Mezopotamiji i biblijske izvještaje u Post 1–2. Pregled tekstova iz Mezopotamije pokazuje da sve ondje prisutne tradicije naglašavaju božanske elemente u konstituciji čovjeka, a analiza Post 1–2 otkriva da se oba biblijska izvještaja, i svećenički i jahvistički, takvim idejama protive. Svećenički opis stvaranja čovjeka na sliku Božju (Post 1,26-27) niječe supstancijalnu vezu Boga i čovjeka, koju ističe babilonska tradicija o stvaranju čovjeka od božanskog mesa i krvi, i uvažava samo formalnu vezu, odnosno rašireno uvjerenje o sličnom obliku ljudskog i Božjeg lika. Prema mišljenju svećeničkoga pisca čovjek je sazdan od zemaljske materije, ali oblik ljudskog tijela izvana i iznutra nalikuje Božjem liku i taj božanski oblik omogućuje zemaljskoj materiji bogoliko djelovanje. Jahvistički opis stvaranja čovjeka od praha i daha života (Post 2,7) negira postojanje klice života u zemljanoj konstituciji čovjeka, što naglašava sumerska tradicija o stvaranju čovjeka od božanske zemlje, te pokazuje da je čovjek u svojoj biti smrtno biće. U zaključku studije iznose se najvažniji rezultati te ukazuje na važnost zemaljske antropologije u Post 1–2 za suvremeni teološki diskurs i za kršćansku vjeru. - The study explores the human constitution in Gen 1–2, observing some major texts on the creation of humans in Mesopotamia and the biblical reports in Gen 1–2. The survey of the Mesopotamian texts shows that all Mesopotamian traditions emphasize divine elements in the human constitution, and the analysis of Gen 1–2 reveals that both biblical reports, the Priestly and the Yahwist, refute such ideas. The Priestly description of the creation of humans at the image of God (Gen 1,26-27) denies the substantial connection between God and humans, which is stressed by the Babylonian tradition on the creation of humans from the divine flesh and blood, and confirms only the formal connection, the widespread opinion that the human form is similar to the divine form. For the Priestly writer, the human beings are made of the earthly material, but the form of the human body is similar outwardly and inwardly to the divine form, and the divinelike form enables the earthly material to perform divinelike actions. The Yahwist description of the creation of humans from the dust and the breath of life (Gen 2,7) denies the existence of the seed of life in the earthy human constitution, which is emphasized by the Sumerian tradition on the creation of humans from the divine earth, and it shows that the humans are essentially mortal beings. The conclusion of the study summarizes the major results and indicates the relevance of the earthly anthropology in Gen 1–2 for the contemporary theological discourse and the Christian faith.

Balićev pristup [Elektronička građa] / Dario Škarica.
Bibliografske bilješke uz tekst. - Sažetak ; Summary. - Glavni je cilj ovog članka ponuditi cjelovit prikaz Balićeva neoskolastičkog pristupa. Istraživanjem raznih iskaza, uglavnom međusobno izoliranih i rasutih po Balićevim radovima prema sredini XX. st., identificirane su sljedeće tri temeljne značajke Balićeva pristupa: prvo, historijsko-kritička metoda (izrijekom preferirana u odnosu na spekulativni pristup), drugo, privrženost rimokatoličkim dogmama kao jednoj od normi prema kojima vrednujemo filozofske sisteme i, treće, postojano zagovaranje načela intelektualne slobode i otvorenosti prema raznim skolastičkim sistemima kao i prema modernoj znanosti i filozofiji (u okviru dogme). - The main aim of this paper is to provide an integrated exposition of Balić's neo-scholastic approach. Various statements pertinent to the approach, mostly isolated from one another and scattered through Balić's works towards the very middle of the 20th century, were studied to serve as a basis for the exposition. As a result, three main features of Balić's approach were identified: firstly, the historical-critical method (explicitly preferred to the speculative approach); secondly, a sturdy adherence to Roman Catholic dogma as a norm for evaluating philosophical systems; and, thirdly, the insistent endorsement of the principle of intellectual freedom and openness to various scholastic systems as well as to modern philosophy and science (restricted only by dogma). In addition, this paper introduces some new arguments for the influence of Louvainneo-scholasticism on the formation of Balić's approach.

Izazov solidarnosti i mogućnosti vjerskog odgoja srednjoškolaca u Republici Hrvatskoj pred fenomenom migracijske krize u Europskoj uniji [Elektronička građa] / Mihael Prović.
Bibliografske bilješke uz tekst. - Sažetak ; Summary. - Autor u radu istražuje utjecaj katoličkog odgoja prema Kurikulumu nastavnog predmeta katolički vjeronauk za osnovne škole i gimnazije u Republici Hrvatskoj na promicanje solidarnosti pred fenomenom migracijske krize u Europskoj uniji. Vrijednosti katoličkog odgoja, prema Kurikulumu, uspoređuju se s vrijednostima Europske unije i njezinih temeljnih dokumenata, poput Ugovora o Europskoj uniji, kako bi se došlo do sagledavanja i racionalizacije izazova suživota domaćeg stanovništva i migranata. Metodom komparacije proučavat će se vrijednosti Katoličke Crkve koje se pronalaze u predmetu katolički vjeronauk za srednje škole, a proizlaze iz Svetog pisma i tradicije Crkve, tj. katoličkoga vjerskog odgoja, te vrijednosti Europske unije, koje proizlaze iz njezinih temeljnih dokumenata. Proučavajući problematiku i izazove multinacionalnoga i plurikulturalnoga društva, u kojem se još uvijek traže rješenja i mogućnosti međuljudskih odnosa, autor želi ponuditi neke ideje, kao moguća rješenja migracijske krize unutar Europske unije, kako bi se preko katoličkog odgoja i obrazovanja, tj. preko „načela solidarnosti” prihvatio i ostvario suživot u različitosti, toleranciji i miru, gdje bi svatko imao pravo slobodno živjeti svoj svjetonazor te nacionalni i vjerski identitet. - The paper is exploring the impact of religious education in promoting solidarity on the phenomenon of migration crisis in the European Union, according to the Curriculum of Catholic Religious Education for primary and secondary education (high school) in Croatia. According to the Curriculum, the values of Catholic education are compared with the values of the European Union and its basic documents such as the Treaty on European Union to understand and rationalize the challenges of the coexistence of the local population and migrants. The comparative approach is used to explore the values of the Catholic Church (found in Scripture and Church Traditions) and the values of the European Union (found in Treaty on European Union) which can be found in the subject of Catholic Religious Education for secondary education. Researching the issues and challenges of a multinational and pluricultural society in a sense of human relations, the author offers some ideas as possible solutions to the migration crisis within the European Union. It could be achieved within Catholic Religious Education, i.e. through the ”principle of solidarity” to accept and achieve coexistence in diversity, tolerance and peace, where everyone would have the right to exercise the right to a free worldview and national and religious identity.

Izazovi nove genetike u suvremenom društvenom i vrijednosnom kontekstu [Elektronička građa] : etička analiza mogućnosti i rizika / Mislav Kutleša, Dario Kral.
Bibliografske bilješke uz tekst. - Sažetak ; Summary. - Rad proučava suvremeni napredak na području genetike koji zahvaljujući velikim probojima u znanstvenom razumijevanju uloge gena u živih bića i razvoju (bio)tehnologije nudi nove primjene i mogućnosti na području zdravlja i poboljšanja čovjeka. U radu se nastoji ove napretke promatrati u suvremenom društvenom i moralnom kontekstu koji se često tumači i razumije kroz pojam postmodernizma. Priznajemo velike potencijale novih (bio)tehnologija, ali upozoravamo kako, budući da spomenuti kontekst ne nudi jasno definirane etičke standarde kao ni jasan koncept čovjekove prirode, postoji znatan rizik zloporabe tih (bio)tehnologija. Ti rizici najčešće se povezuju s ugrožavanjem slobode i jednakosti, a nerijetko se dovode i u vezu s pitanjima smisla i statusa čovjeka kao osobe. Dapače, nastojimo ukazati kako upravo problemi i nerazumijevanja na ontološkom području prethode društvenim neredima. Imajući to na umu, ne mislimo kako nove (bio)tehnologije po sebi stvaraju nove opasnosti, koliko imaju potencijal naglasiti one koje su već prisutne. Kako nova genetika intervenira u samu arhitekturu života, stavljajući je na raspolaganje ljudskim rukama, sam život bi mogao postati tržišna i manipulativna roba. Odgovor na te moguće zloporabe nije u odbacivanju novih (bio)tehnologija, nego u prepoznavanju nedvosmislenog statusa čovjeka kao bića koje je vrijednost u sebi i za sebe, a koju je nemoguće prepoznati ako se zanemaruje transcendentna dimenzija čovjeka. - This thesis paper examines contemporary advances in the field of genetics which, due to the vast improvement in scientific understanding of gene's role in the organism's life and development of various new biotechnologies, offers or promises to offer, new applications in healthcare and human enhancement which can be considered revolutionary. In this paper, we try to consider these advancements in contemporary social and moral context, most often understood through the term postmodernism. While we acknowledge huge potential benefits of these new biotechnologies, we argue that, since aforementioned contemporary context lacks clearly defined ethical standards and, furthermore, clear concept of human nature, there is a substantial risk of misuse of these biotechnologies. Most often, those risks are identified as being potential social risks concerning freedom and equality, but rarely are they thought in relation to the meaning or status of human person which is what we want to highlight. Furthermore, we identify exactly these problems as those that precede social problems. Having that in mind, we do not think that new biotechnologies create per se new hazards as much as they have potential to exaggerate those already existing. We present a thesis that, in contemporary context, new genetics is strongly influenced by market forces. Since new genetics intervenes in the architecture of life itself, giving it at human disposal like never before, life could become a commodity. We find that commodification of human life to be degrading for human person, which leads to gross abuses of personal and social values of human being. To counter those abuses, we believe the answer lies in having clearly defined as being the status of human person that has intrinsic value in itself, which is impossible without taking into account the transcendental value of human beings.

LAPIĆ, Ivica Karlo
Kršćansko teološko-filozofsko propitivanje temelja gostoljubivosti [Elektronička građa] / Ivica Karlo Lapić.
Bibliografske bilješke uz tekst. - Sažetak ; Summary. - Provedeno istraživanje u ovoj nam prezentaciji nudi moralnu perspektivu gostoljubivosti u kojoj se sloboda vjerovanja konfigurira kao intencionalnost vjere. Propitivanja u biblijskom i filozofskom dijelu imala su namjeru izdvojiti temeljne strukture gostoljubivosti kao univerzalno antropološke u svojoj teologalnoj vezi i intrinzičnoj ljudskoj dinamici. Kristovo otajstvo, uz premise cjelokupne hermeneutike ljudske gostoljubivosti ocrtane u svjetlu objave, postaje privilegirano teološko mjesto njezinog cjelovitog i konačnog poimanja i njezinog potpunog ostvarenja (Mt 25,31-46). Fenomenologija intersubjektivnosti predstavlja subjekt u relaciji kao ontološki temelj gostoljubivosti koja u svjetlu objave postaje hermeneutički put i sam razlog njezine vjerodostojnosti. Dinamika međuljudskih odnosa u gostoljubivom odnosu podrazumijeva biti-s-drugim i biti-za-drugoga, u kontinuiranom kretanju otvorenosti prema drugosti u agapičnom poretku. Ta ga dinamika u potpunosti upisuje u temelj registra kršćanskoga moralnog djelovanja. Izvorni čovjek u biblijskoj objavi pokazuje svoju sposobnost otkrivanja izvorne Božje nakane u gostoljubivoj dobrodošlici, kao čin svjesne i odgovorne slobode za dobrobit drugoga i kao dar i brigu, koji su kadri nadvladati bilo kakvu drugost/razliku, čak i onu najradikalniju. - The research carried out in this presentation offers us a moral perspective of hospitality in which the believing freedom is configured as an intentionality of faith. Both the research in the biblical part and in the philosophical one, have circumscribed the foundational structures of hospitality as universally anthropological in its theological connection and intrinsic human dynamic. In this way, the premises of the overall hermeneutics of human hospitability are outlined in the light of Revelation, in which the mystery of Christ becomes the theological place of his full and definitive comprehension, and its sequela as a form of its full realization. The phenomenology of inter-subjectivity presents the person in relationship as the ontological foundation of hospitality which, in the light of Revelation, becomes the hermeneutical path and the very reason for its credibility. The dynamics of interpersonal relationships in a hospitable relationship imply being-with-the-other and being-for-the-other, in a continuous movement of openness to otherness in the agape order. This dynamic inscribes it fully in the foundation of the register of Christian moral action. The original human, described by the biblical revelation, showed his ability to disclose the sense of God's original intention in welcoming hospitable, as the act of conscious and responsible freedom for the good of the other, and as a gift and care, able to overcome any strangeness/difference, even the most radical.

Moralno-pastoralno djelovanje Crkve pred izazovom iseljavanja i pada nataliteta u Istočnoj Hrvatskoj [Elektronička građa] / Vladimir Dugalić, Dražen Živić. - Graf. prikazi.
Bibliografske bilješke uz tekst. - Sažetak ; Summary. - Istok Hrvatske danas se suočava sa sve većim valom iseljavanja koji, uz već više desetljeća snažnu depopulaciju, ove krajeve stavlja u vrlo nepovoljnu situaciju. U prvom dijelu rada analiziraju se stoga migracijski trendovi i razmjeri depopulacije kao i najvažniji uzroci koji su doveli do ove situacije te se ističu i neke nužne pronatalitetne i gospodarske mjere. Naime, u razdoblju od 2011. do 2018. godine istočnohrvatske županije ostvarile su negativan saldo vanjske migracije od (najmanje) 46.606 stanovnika, što je u odnosu na ukupan broj stanovnika 2011. godine 5,8 %, pri čemu, očekivano, prednjače Osječko-baranjska i Vukovarsko-srijemska županija. Međutim, neka istraživanja pokazuju da je stvarni broj iseljenih iz Hrvatske u inozemstvo možda i do tri puta veći od službenoga broja. U drugom dijelu rada ističe se važnost moralno-pastoralnog i socijalno-karitativnog djelovanja Crkve, osobito u pronalaženju odgovora na sve češće obiteljske migracije, ali i u iznalaženju novih oblika pastoralne skrbi za iseljene. Crkva je pozvana, s jedne strane, duhovno-pastoralno pratiti one koji su otišli u inozemstvo te im poručiti kako nisu zaboravljeni i da se s radošću čeka njihov povratak, a s druge, pozivati mlade ljude i obitelji da ostanu u svojoj zemlji i tu grade svoju budućnost. Osim toga, u situaciji snažne depopulacije Crkva ima zadaću, snagom svoga proročko-evangelizacijskog poslanja, promicati „evanđelje obitelji” i poticati mentalitet u kojem se dijete promatra kao dar, a ne teret za obitelj. Reorganizacija pastorala braka i obitelji te iznalaženje novih oblika karitativnog djelovanja, nameću se kao prioriteti moralno-pastoralnog djelovanja Crkve. - The east of Croatia is facing an increasing wave of emigration which, with a strong depopulation for several decades, puts these areas in a very unfortunate situation. Therefore, the first part of the paper analyses migration trends and the extent of depopulation as well as the most important causes that led to this situation, and points out some necessary pro-birth and economic measures. Namely, in the period from 2011 to 2018, the eastern Croatian counties achieved a negative balance of external migration of (at least) 46,606 inhabitants, which is 5.8% of the total population in 2011, and, as expected, Osijek-Baranja and Vukovar-Srijem counties are in the lead. However, some researches show that the actual number of emigrants from Croatia abroad is perhaps up to three times higher than the official number. The second part of the paper points out the importance of moral-pastoral and social-charitable activities of the Church, particularly in finding answers to the increasing family migrations, but also in finding new forms of pastoral care for emigrants. On the one hand, the Church is called to spiritually and pastorally accompany those who have gone abroad and to tell them that they are not forgotten and that we look forward to their return, and on the other hand, to invite young people and families to stay in their country and build their future here. Moreover, in a situation of strong depopulation, the Church has the task, by the power of her prophetic-evangelizing mission, to promote the "gospel of the family" and to encourage a mentality in which the child is seen as a gift rather than a burden to the family. The reorganization of the pastoral care of marriage and family and finding the new forms of charitable activities arise as priorities of the moral and pastoral activity of the Church.

HAVEL, Boris
O uporabi riječi poput priroda, sudbina i sreća u prijevodima Staroga zavjeta [Elektronička građa] / Boris Havel.
Bibliografske bilješke uz tekst. - Sažetak ; Abstract. - Autor u članku pokazuje da u starozavjetnomu hebrejskom svjetonazoru nisu postojali mnogi koncepti, pa time ni nazivi, kojima se opisuju apstrakcije izvan čovjekovih emocija, volje, uma i odnosa s Bogom. Među takve se ubrajaju „sudbina“, „sreća“ i „priroda“ u apstraktnomu i konkretnomu smislu. No u suvremenim su zapadnim civilizacijama ti koncepti toliko uvriježeni da je bez njih gotovo nemoguće promišljati o stvarnosti i svijetu. Zato se neke od tih riječi pojavljuju u različitim prijevodima Svetoga pisma Staroga zavjeta. U članku su izdvojeni primjeri prevoditeljske uporabe takvih riječi te je na temelju hebrejskoga izvornika predloženo propitivanje prevoditeljskih rješenja u kojima se one nalaze. - Old Testament Hebrew worldview and language did not contain several concepts and words relating to abstract phenomena outside human emotions, will, mind and man’s relation to God, which are common to our modern speech and understanding of reality. Among such concepts are fate, luck, and nature in its abstract and concrete meaning. Some of those concepts can nevertheless be found in translations of the Old Testament. In this article the author presented some examples of use of those words primarily in the Croatian Bible translations and, referring to the source text in Hebrew, proposed their reconsideration.

MATIĆ, Zdravko
Osnivanje i rad Križarske organizacije u Hrvatskoj (1930. - 1945.) [Elektronička građa] / Zdravko Matić, Damir Stručić.
Bibliografske bilješke uz tekst. - Sažetak ; Summary. - Nakon uvođenja Šestosiječanjske diktature 1926. i zabrane rada Hrvatskog orlovskog saveza, već je 1930. osnovana Križarska organizacija kako bi se ponovno sakupila raspršena hrvatska katolička mladež koja je bila organizirana u orlovstvu i koja je bila teško pogođena ukidanjem svoje Orlovske organizacije. Nova Križarska organizacija temeljila se na načelima međunarodne organizacije Apostolata molitve, i to njezina ogranka za mladež koji se u Francuskoj nazivao „Croisade Eucharistique“. Jedino je pod tim uvjetom nova organizacija mogla biti priznata od beogradskog režima, ali ipak uz mnoge teškoće, koje su postupno bile nadvladane. Po želji zagrebačkog nadbiskupa koadjutora Alojzija Stepinca 1936. g. Križarska organizacija postaje dio Katoličke akcije i djeluje u skladu s njezinim pravilima, ali je zadržala svoje ime i duhovnu baštinu naslijeđenu od dokinute Orlovske organizacije. Križarska organizacija bila je u svojim društvima prisutna u svim hrvatskim biskupijama i bila je najbrojnija katolička organizacija za mladež u to vrijeme. U njoj su tisuće mladića i djevojaka primali solidan katolički odgoj i formirali se za vjerne članove Katoličke Crkve, njezine suradnike i apostole. Da bi zaštitio članstvo od komunističkih progona, nadbiskup Alojzije Stepinac raspustio je u srpnju 1945. g. sve organizacije Katoličke akcije, među kojima je bila i Križarska organizacija. - After the dictatorship of King Aleksandar Karađorđević on January 6 and the ban on the Croatian Eagle Alliance, the Crusaders Organization was founded as early as in 1930, based on the principles of the Apostolate of Prayer, i.e. its branch for young people called Croisade Eucharistique, introduced and implemented in Orlovstvo (Eaglehood) by Dr Ivan Merz in 1923. On February 5, 1936, the Archbishop of Zagreb, Coadjutor Alojzije Stepinac, founded the Diocesan Council of Catholic Action, which operated in accordance with the Rules of Catholic Action. The Crusaders Organization formally operated until July 1945, when the Communists came to power and they would cease their work. They were dissolved personally by Archbishop Alojzije Stepinac in agreement with the leadership of the Catholic Action, to which the Crusaders also belonged.

Pastoralna skrb za hrvatske iseljenike [Elektronička građa] / Tomislav Markić.
Bibliografske bilješke uz tekst. - Sažetak ; Summary. - Pastoralna skrb za hrvatske iseljenike stara je koliko su stare i migracije hrvatskih katolika ponajprije u obližnje zemlje, gdje danas žive i priznati su kao hrvatska nacionalna manjina, a zatim u posljednjih 125 godina kao skrb za iseljenike u europskim i prekomorskim zemljama. Poseban zamah pastoralna je skrb za hrvatske iseljenike doživjela europskim valom iseljavanja Hrvata u 20. stoljeću te osnivanjem Ravnateljstva dušobrižništva za Hrvate u inozemstvu (Directio Nationalis Operum pro Migrationibus Croatis) 25. lipnja 1966. godine. Nakon kratkoga povijesnoga pregleda razvoja hrvatske inozemne pastve u članku se iznose statistički podaci (stanje 31. prosinca 2018.) kao i pregled aktualnoga stanja i rasporeda pastoralnih prisutnosti po cijelome svijetu. U posljednjem dijelu članka riječ je o aktualnim izazovima i nekim posebnostima pastoralne skrbi za hrvatske iseljenike i njihove potomke. - Pastoral care for Croatian emigrants is as old as the migration of Croatian Catholics, primarily to nearby countries, where they live today and are recognized as a Croatian national minority, and then in the last 125 years as pastoral care for emigrants in European and overseas countries. Pastoral care for Croatian emigrants experienced a special impetus with the European wave of emigration of Croats in the 20th century and the establishment of the Pastoral Directorate for Croats Abroad (Directio Nationalis Operum pro Migrationibus Croatis) on June 25, 1966. After a brief historical overview of the development of the Croatian foreign flock, the article presents statistical data (as at 31 December 2018) as well as an overview of the current state and distribution of pastoral presences around the world. The last part of the article is about the current challenges and some special characteristics of pastoral care for Croatian emigrants and their descendants.

Pismo fra Pavla Vučkovića iz sužanjstva u Urfi (Edesa) 1699. godine [Elektronička građa] / Marko Rimac, Josip Dukić.
Sadrži i: Pismo fra Pavla Vučkovića na str. 206-207. - Bibliografske bilješke uz tekst. - Sažetak ; Summary. - Sudbina ramsko-sinjskih franjevaca koji su se 1698. na svome imanju u Čitluku pokraj Sinja suprotstavili osmanskoj vojsci koju je predvodio Mustafa-paša Daltaban relativno je dobro poznata iz kroničarskih opisa. Većina fratara izgubila je život, a gvardijan ramskog, tj. sinjskog samostana fra Pavao Vučković odveden je u osmansko sužanjstvo. O njegovoj se sudbini ipak dugo nije ništa znalo, tako da je pismo, otkriveno u proljeće 2015. u Državnom arhivu u Veneciji, koje je on poslao iz zatočeništva u Urfi (danas Şanlıurfa u Turskoj, nekoć drevna Edesa), prekinulo dugo razdoblje strepnje oko njegove sudbine. Pismo je fra Pavao uputio svome bratu, serdaru Tadiji, zatim sinovcima, rodbini i prijateljima. Više je zanimljivih okolnosti koje su pismom rasvijetljene, a neke prethodne tvrdnje o njegovoj sudbini poslije zarobljavanja dovedene su u pitanje. - The fate of the Rama-Sinj Franciscans who opposed the Ottoman army led by Mustafa-pasha Daltaban on their property in Čitluk near Sinj in 1698 is relatively well known from chronicle descriptions. Most of the friars lost their lives, and the Guardian of the Rama, i.e. Sinj monastery, Fr. Pavao Vučković, was taken into Ottoman captivity. However, nothing was known about his fate for a long time, so the letter discovered in the spring of 2015 in the State Archives in Venice, which he had sent from captivity in Urfa (today Şanlıurfa in Turkey, once ancient Edessa), interrupted a long period of anxiety about his fate. Fr. Pavao sent a letter to his brother, Serdar Tadija, then to his nephews, relatives and friends. There are several interesting circumstances that have been clarified in the letter, and some previous claims about his fate after being taken prisoner, have been called into question.

VUKŠIĆ, Tomo
Smanjivanje broja katolika u Bosni i Hercegovini i potreba da se ono zaustavi [Elektronička građa] / Tomo Vukšić. - Graf. prikazi.
Bibliografske bilješke uz tekst. - Sažetak ; Summary. - Vrlo je uočljivo drastično smanjivanje broja katolika u Bosni i Hercegovini tijekom posljednjih 30 godina. Od 760.852, koliko ih je bilo 1991. godine, prema državnom popisu iz 2013. godine ostalo ih je 544.780, odnosno prema crkvenim procjenama na kraju 2018. na tom području bilo bi 365.688 katolika. Taj proces započeo je za vrijeme rata (1991. - 1995.) progonima i iseljavanjem zbog straha i nastavio se nakon toga zbog nesigurnosti, izostanka i onemogućavanja održivog povratka, novog iseljavanja i negativnog priraštaja. Katolička Crkva u BiH od 2003. do 2018. godine bilježi gubitak od 99.133 vjernika. Odnosno, Banjolučka biskupija je tijekom posljednjih dvadesetak godina ostala bez 45,71 % vjernika, koji su na njezinu području bili 1999. godine, Sarajevska je ostala bez 32,48 % u odnosu na 2002. godinu, Mostarska bez 11,75 % nakon 2006., a Trebinjska bez 13,04 % od 2005. godine. U tom općem gubitku vlastiti negativan priraštaj sudjeluje s 23.214, što znači da se iz BiH u tom razdoblju, prema crkvenim procjenama, iselilo 75.919 katolika. Ovaj rad podijeljen je u šest naslova: Okolnosti i zakonski okviri suvremene društvene zbilje u BiH, Depopulacija i denatalitet pogađaju cijelu BiH, Smanjivanje broja katolika ponovno postao proces, Negativan priraštaj i novo iseljavanje katolika, Uloga državne vlasti i međunarodne zajednice u traženju rješenja te Još neki izazovi Katoličke Crkve u složenom društvu BiH. - After the number of Croats and Catholics in B&H was almost halved at the end of 20th century due to war persecution and displacement, emigration and negative growth became their new major problem. According to church data, after surviving the war tragedy and an initial slight comeback after the war, with new emigration and negative growth, the Catholic Church in B&H from 2003 to 2018 registered a loss of 99,133 believers. In other words, during the last 20 years, the Diocese of Banja Luka has lost 45.71% of believers, who were in the diocese in 1999. The Diocese of Sarajevo has lost 32.48% compared to 2002. The Diocese of Mostar has experienced a loss of 11.75% after 2006. And finally the Diocese of Trebinje has lost 13.04% since 2005. In this general loss according to church estimates, 75,919 Catholics emigrated from B&H during that period resulting in negative growth of 23,214 people. The demographic decline of Catholics and Croats in B&H after the war is the consequence of many simultaneous causes. The most important among these are: lack of political and material support for the return of refugees and displaced persons; very negative natural growth; new emigration; high unemployment rates that encourage emigration in search of employment; political and legal uncertainty; corruption and frustration; new emigration as a consequence of plans by developed countries to replace their own demographic losses and to gain labour workers; insufficient social and material support for women who wish to give birth; the growing crisis of marital morality and secularization; a crisis of awareness among believers about the value of life and parental collaboration with the Creator God; young people leaving, and the high average age of the population, etc.

HORVAT, Marijana
Usporedba biblijskih citata iz Divkovićevih Besjeda s Kašićevom Biblijom [Elektronička građa] / Marijana Horvat, Andrea Radošević.
Bibliografske bilješke uz tekst. - Sažetak ; Summary. - Matija Divković svoje je najopsežnije djelo ‘Besjede’ sastavio prema četirima latinskim zbirkama propovijedi. Iako nastalo u 17. stoljeću, ono većim dijelom slijedi retoričke i strukturne značajke srednjovjekovnih tematskih propovijedi koje su se u dobroj mjeri oslanjale na biblijski tekst, ali i na brojne komentare biblijskih knjiga. U ovom radu istražit će se Divkovićev odnos prema prevođenju biblijskih citata koji u ‘Besjedama’ imaju različite funkcije u skladu s načelima ‘ars praedicandi’. U svrhu analize njegovih interveniranja u biblijski tekst, čime je ponajprije pridonosio prenošenju jasne, utemeljene i ispravne moralne pouke, njegov će se prijevod usporediti s Vulgatom i Kašićevom Biblijom koja je po vremenu i okolnostima nastanka najbliža ‘Besjedama. Osim toga, takva usporedba pridonosi poznavanju razmjera Divkovićeva utjecaja ne samo na franjevačku književnost 17. i 18. stoljeća nego i na isusovca Bartola Kašića, autora prvoga prijevoda Biblije na hrvatski jezik. Vrijednost je tog prijevoda, među ostalim, i u tome što pokazuje da se Kašić koristio jezično-stilskim svojstvima starijih prevoditelja nabožnih djela i biblijskih tekstova. Osim analize Divkovićevih tumačenja biblijskih navoda i njihova stilskog obilježavanja, naša je namjera usporedbom s Kašićevom Biblijom pokazati da je na jezično-stilskoj razini postojala uporabna norma koju su nabožni pisci slijedili, tj. literarna koine koja je povezivala hrvatsku književnost dalmatinsko-dubrovačkoga kruga s bosanskofranjevačkim, a koja je utjecala na širenje štokavštine u pisanoj praksi i procese standardizacije hrvatskoga jezika na štokavskoj osnovici. - Today it is well known and often highlighted that the Franciscan Matija Divković is the founder of Bosnian Franciscan vernacular literature written in Croatian language. His works influenced the Franciscan literature in 17th and 18th century by the choice of themes of moral and didactic texts and especially by the inheritance of stylistic and language features. Many other later Franciscan writers, who wrote in Bosnia and Herzegovina, followed the track of Divković in shaping the literary language. His influence was extended over other religious writers on the Croatian soil in all parts of Bosna Argentina, for example Jesuit Bartol Kašić, who is the author of the first Bible translation into Croatian. His Bible is very important, among other things, because it shows that Kašić follows some specific language and stylistic features of older Croatian translators of religious literature and Bible texts. Therefore, in this paper on the examples of Bible quotes, which Divković's Sermons abound, and with their comparison in Kašić's Bible translation, we will try to show the presence of stable usage in which certain stylistic and language features became a norm or a literary koinè which the religious writers respect. This koinè was connecting the Croatian literature of Dalmatian and Ragusan circle with the Bosnian Franciscan circle and could give a big contribution to spreading shtokavian in writing and to the process of standardization of Croatian language on shtokavian basis. We will also mention the relationship between the observed works and sources from which they were translated. Kašić translated from Vulgata. As he usually translated ad litteram, his dependence on the original is most obvious in Bible. On the other hand, Divković had liberal approach to translation, but the starting assumption would be that he was most faithful to the source in Bible quotes.

Vertikalne strukture kršćanskog režima istine [Elektronička građa] / Žarko Ament.
Bibliografske bilješke uz tekst. - Sažetak ; Abstract. - Rad analizira formaciju moći kršćanskog režima istine promatrajući je u kontekstu Foucaultova pojma strategijskih cjelina. Posebno se analizira seksualna formacija moći kroz tri žarišne točke njezina djelovanja. Prva se žarišna točka formira unutar sukoba starozavjetnog režima istine i kanaanskog kulta plodnosti. Druga žarišna točka formirana je pod utjecajem antičke filozofske misli, ponajprije na filozofiji stoika, na ideji o uzdržavanju od seksualnog čina kao otvaranju božanskoj inspiraciji te medicinskim spoznajama antike. Treća žarišna točka formira se oko mehanizama kontrole kršćanskog režima istine kroz klasifikaciju, regulaciju, zabranu, tarifiranje prijestupa i korekcije nauka. Zadaća je formacije moći vertikalno strukturiranje režima istine u njezinoj antropomorfnoj i androcentričnoj imanentnosti. - This paper analyses the formation of power of the Christian regime of truth in the context of Foucault’s concept of strategic formations. The main emphasis is on the sexual formation of power in three focal points of its agency. The first focal point is formed around the conflict between the Old Testament truth regime and the Canaan cult of fertility. The second focal point is formed around the influence of ancient philosophical thought, primarily through the philosophy of stoicism, which sees abstinence from the sexual act as an opening to divine inspiration and around medical knowledge of antiquity. The third focal point is formed around control mechanisms of the Christian regime of truth through classification, regulation, prohibition, tariffing offences and corrections of doctrine. The main purpose of the formation of power is the vertical structuring of the regime of truth in its anthropomorphic and androcentric immanence.

MAGDA, Ksenija
Zašto je i kako Kraljevstvo Božje za djecu? [Elektronička građa] : egzegetsko-teološki prikaz Marko 10, 13-16 / Ksenija Magda, Tea Šestak.
Bibliografske bilješke uz tekst ; bibliografija: str. 348. - Sažetak ; Abstract. - Ovaj se rad bavi egzegetskim pristupom Mk 10, 13-16, gdje Isus u prizoru s djecom podučava odrasle o kraljevstvu Božjem. Isus naglašava da „takvim pripada kraljevstvo Božje“ (Mk 10, 14). U središtu je pozornosti teza da kraljevstvo Božje pripada onima koji prepoznaju njegovu „kontrakulturu“ u odnosu na poredak u svijetu, prihvaćajući one najmanje i služeći najmanjima. To su ljudi koji sami sebe vide u potpunoj ovisnosti o Bogu, njegovoj ljubavi i milosti. Članak pokazuje da su u tom Markovom tekstu djeca ponajprije pokazna lekcija za Isusovu poduku učenicima. Isus nema namjeru pozivati odrasle na oponašanje djece u nekim navodnim dječjim nedužnim karakteristikama. Iako rad ne dijeli mišljenje da se ulazak u kraljevstvo Božje postiže nekom dječjom nevinošću, posredno ipak može mnogo govoriti o djeci, tj. kako ih oni koji pripadaju kraljevstvu Božjem trebaju prigrliti i blagoslivljati. Briga o „malenima“ (ne samo o djeci) je, naime, prvi znak da su ljudi prepoznali bit kraljevstva Božjega i da mu pripadaju. - This paper is an exegetical approach to Mark 10:13-16, where children become Jesus’ object lesson in the instruction of adults about the nature of the kingdom of God. Jesus points out: ‘for it is to such as these that the kingdom of God belongs’ (10:14). The paper pursues the thesis that the kingdom of God belongs to people who understand its counter-cultural nature with regards to the world, by accepting and ministering to the “least.” These are people who see themselves fully dependent on God, his love and his mercy – like children. The paper suggests that, in Mark, children have been the object in Jesus lesson, and help him confront adults with the nature of the kingdom of God. Jesus does not point to alleged innocence of children, which adults must mimic to enter God’s kingdom. However, although this paper does not presuppose a child’s ‘salvation’ on account of their innate innocence which adults have somehow lost, but should regain – as is often automatically understood from this text – indirectly it does concern the children. Pretenders to the kingdom of God should accept and bless the “little ones”. The care for them is, namely, the first sign that a person belongs to the kingdom of God.

MATIJEVIĆ, Ivan, arheolog
Židovska vjerska zajednica u Saloni [Elektronička građa] / Ivan Matijević. - Ilustr.
Bibliografske bilješke uz tekst. - Sažetak ; Summary. - Prema sadržaju Peregrinova natpisa podignutoga 382. godine u cemeterijalnoj bazilici na Manastirinama G. B. de Rossi je pretpostavio postojanje židovske vjerske zajednice i njezinoga groblja u Saloni (coemeterium legis Iudaicae). Njegova je teza osnažena kada je F. Bulić na Gospinu otoku, oko stotinu metara istočno od salonitanskih gradskih zidina, pronašao ulomak sarkofaga s prikazom menore datiran u početak 4. stoljeća. Prisutnost Židova u Saloni indiciraju i neki drugi nalazi: keramička svjetiljka s prikazom menore iz 4. stoljeća, zatim gema s prikazom menore, šofara, etroga i lulava datirana između 4. i 7. stoljeća. Izravan dokaz za postojanje židovske vjerske zajednice je ulomak natpisa koji spominje tri religijske skupine: Rimljane, Židove i kršćane. Takav redoslijed odgovara vremenu kada kršćanstvo još nije bilo afirmirano i stoga natpis valja datirati u kraj 3. ili početak 4. stoljeća. Na kraju, mora se spomenuti i nadgrobni natpis Samarijanke No[---], preminule godine 539. i porijeklom iz još uvijek nepoznatog sela Pit[---]. Nemoguće je odrediti je li vjerom pripadala kršćanima ili Samarijancima. - According to the contents of Peregrine’s inscription erected in 382 in the cemetery basilica at Manastirine, G.B. de Rossi assumed the existence of a Jewish religious community and its cemetery in Salona (coemeterium legis Iudaicae). His thesis was strengthened when F. Bulić found a fragment of a sarcophagus depicting a menorah dated to the beginning of the 4th century on Gospin Otok, about a hundred meters east of the Salonitan city walls. The presence of Jews in Salona is also indicated by some other finds: a ceramic lamp depicting a 4th century menorah, then a gem depicting a menorah, a shofar, an etrog and a lulava dating between the 4th and 7th centuries. However, direct evidence for the existence of a Jewish religious community is a fragment of an inscription mentioning three religious groups: Romans, Jews, and Christians. Such order corresponds to the time when Christianity was not yet affirmed and therefore the inscription should be dated to the end of the 3rd or beginning of the 4th century. Finally, the tombstone inscription of the Samaritan woman No [---] who died in 539 and originates from the still unknown village of Pit [---] must also be mentioned. It is impossible to determine whether she belonged by faith to Christians or Samaritans.

Dug put kući - povratak jugoslavenskih iseljenika iz Argentine (1946. - 1951.) [Elektronička građa] / Bojan Simić. - Graf. prikazi.
Bibliografske bilješke uz tekst ; bibliografija: str. 811. - Sažetak ; Summary. - U radu se na temelju arhivskih izvora, stručne literature i onovremenoga tiska analizira povratak jugoslavenskih iseljenika iz Argentine i ostalih dijelova Južne Amerike u prvim godinama nakon Drugoga svjetskog rata. Prati se priprema, organizacija, brojnost, transport, dolazak, smještaj i razmještaj iseljenika u domovini. Analizira se i stručna, nacionalna i spolna pripadnost iseljenika povratnika. Posebna pozornost posvećena je odnosima dviju država, Jugoslavije i Argentine, u ovom pitanju. - Diplomatic, consular and economic relations between the Federal People’s Republic of Yugoslavia and the Republic of Argentina were established on 16 September 1946. The agreement was signed by General Ljubo Ilić, chief of the Yugoslav diplomatic mission in South America, and Juan Atilion Bramuglia, Argentinian Minister of Foreign Affairs and Religion. In the first decade after World War II, the two states had some open problems and unresolved issues such as the question of commercial agreements, Yugoslav political emigration in Argentina, especially the Ustasha movement, Argentine nationalised property in Yugoslavia, visas for entering Argentina etc. Following World War II, Argentina became the country with the most emigrants of Yugoslav origin in the entire Latin America. The major part of those were Croats and Slovenes, while emigrants from Montenegro and Serbia made up a smaller proportion. The issue of Yugoslav immigrants in Argentina was of the greatest importance in the relations between two countries. In the late 1940s, the interests of Yugoslavia and Argentina in this matter were opposed. Both sides wanted to use a qualified work force for building their own country. Yugoslavia tried to recruit immigrants to come back and take part in fulfilment of the Five-Year Plan established in 1947. Argentina on the other hand, wanted to keep able-bodied people for building its own industry. The Yugoslav government sent ships for immigrants and organised housing and jobs for them upon their return. The majority of them were construction, agriculture, and textile workers. The peak of the repatriation was 1948, when 83% of Yugoslav immigrants returned from Argentina. There was another problem, and that was the different treatment of immigrants with dual citizenship, which especially referred to the children of Yugoslav immigrants who were born on Argentine soil.

Medijska analiza sadržaja online medija o fenomenu suvremenog iseljavanja iz Hrvatske [Elektronička građa] / Tado Jurić, Lucija Kardaš, Anja Bakota. - Graf. prikazi.
Bibliografija: 7 jed. ; elektronički izvori: str. 486-494. - Sažetak ; Summary. - U radu su predstavljeni rezultati istraživanja analize hrvatskih online medija (web portali) o temi iseljavanja iz Hrvatske. Istraživani su koncept i slika o iseljavanju Hrvata gledani/prikazivani kroz prizmu medija u Hrvatskoj. Tema „iseljavanje iz Hrvatske” analizirana je u člancima sljedećih hrvatskih web portala: Večernji list, 24 sata i Index.hr te Deutsche Welle, međunarodnom njemačkom javnom medijskom servisu. Analiza medija provodila se od listopada 2018. do siječnja 2019. Mediji su izabrani po kriteriju čitanosti te opsega i dostupnosti medijskim publikama. Korištena je zadana matrica istraživanja podijeljena u šest kategorija gdje su se na navedenim portalima analizirali članci metodom analize diskursa. Analizom medijskog sadržaja kodirana su i kategorizirana 152 analizirana članka. Prema zadanim kategorijama istraživane su: opće značajke članaka, vrijednosna orijentacija, odnos autora prema iseljavanju i zastupljenost pojma u članku, naslovi, grafički prikazi u člancima te komentari čitatelja na članak. Većina objavljenih tekstova o iseljavanju iz Hrvatske napisana je u negativnom kontekstu. Članci pak o pozitivnim iskustvima preseljenja i odlaska u drugu državu zaista potiču daljnje iseljavanje, odnosno neodlučne potiču na razmišljanje o opciji iseljavanja. Zaključujemo kako mediji koji djeluju u Hrvatskoj jesu pristrani pri prikazivanju teme iseljavanja, jer je vidljivo da su stavovi, odabir osoba za razgovore i citate kao i subjektivnost prisutni u većini članaka. S druge strane, svakako uočavamo i pozitivnu ulogu koju igraju mediji u hrvatskom društvu, čemu svjedoči činjenica da su mediji otvorili više ključnih društvenih tema od samih institucija i službi kojima je to u opisu posla te da svakako djeluju i kao konstruktivan društveni korektiv.

MĄKOSA, Paweł
Poljska između iseljavanja i useljavanja, u kontekstu Crkve [Elektronička građa] / Paweł Mąkosa.
Bibliografske bilješke uz tekst. - Sažetak ; Summary. - Poljsku se ponajprije smatra izvorom migracija, ali posljednjih godina zemlja je postala i mjesto naseljavanja izbjeglica i migranata, koji osobito dolaze iz Istočne Europe. U ovom smo radu najprije pokušali prikazati današnje iseljavanje iz Poljske, a zatim predstaviti priljev stranaca u tu zemlju. Pokazali smo i posljedice iseljavanja za Poljsku. Zatim smo se fokusirali na učenje Crkve o iseljenicima, a posebno na brigu za njihovo duhovno dobro. Drugi dio članka posvećen je useljenicima u Poljsku. Razmišljanje završava predstavljanjem trenutačnih podataka o broju imigranata i razlozima naseljavanja u Poljskoj. Prikazali smo poljsku državnu politiku s tim u vezi te prešli na stav Rimokatoličke Crkve u pogledu prihvaćanja izbjeglica i migranata. Na temelju provedenih analiza ustanovili smo da je politika poljske države otvorena uglavnom prema pridošlicama iz Istočne Europe, dok potencijalnim migrantima sa Srednjeg Istoka i iz Afrike, poljska Vlada nudi pomoć samo u privremenom naseljavanju. S druge strane, Rimokatolička Crkva u Poljskoj naglašava potrebu otvorenosti prema svim ljudima kojima je pomoć potrebna, premda primjećuje da je potrebno educiranje javnosti o tom pitanju. Rješenja prihvaćena u Poljskoj rezultirala su masovnim priljevom migranata iz istočnoeuropskih zemalja, posebno iz Ukrajine. - Poland is associated primarily as a source of migration, but in recent years the country has become a place of settlement for refugees and migrants coming in particular from Eastern Europe. In this paper we first set out to present the current emigration from Poland, then presented the influx of foreigners to the same country. We also presented the consequences of emigration from Poland. Then we concentrated our analysis on the teaching of Church regarding emigrants, and in particular the care for their spiritual good. The second part of the article was devoted to immigration to Poland. The reflection ended with presentation of current data on the number of immigrants and the reasons for settling in Poland. We demonstrated the Polish state policy in this regard, to move on to the position of the Roman Catholic Church as regards the acceptance of refugees and migrants. Based on the analyses conducted we found that the policy of Polish state is open mainly to newcomers from Eastern Europe, while in relation to Middle East and Africa, the Polish government offers only assistance in temporary settlement of potential migrants. In turn, the Roman Catholic Church proclaims the need to be open to all people in need of help, although it notices the need to educate the public in this matter. The solutions adopted in Poland result in a mass influx of migrants from Eastern European countries, especially from Ukraine.

DA-DON, Kotel
Židovski narod između iseljavanja i useljavanja [Elektronička građa] / Kotel Da-Don.
Bilješke uz tekst. - Bibliografske bilješke uz tekst. - Sažetak ; Summary. - U ovom članku autor analizira osobitu vezu koja postoji između židovskog naroda i Svete zemlje. Židovski narod preživio je brojna iseljavanja i useljavanja u svojem trajnom hodočašću prema „Obećanoj zemlji”. Ta hodočašća uspjela su izgraditi, oblikovati i održati židovski nacionalni identitet u najtežim trenutcima dugotrajnog egzila. Prvi dio članka sastoji se od općenitog uvoda, nakon kojeg slijedi glavni prikaz iseljavanja i useljavanja u povijesti židovskog naroda. U središnjem dijelu članka raspravljat će se o dvjema glavnim temama. Prva je teološko značenje iseljavanja i useljavanja Židova kao znak božanske providnosti te primjena ideja nagrade i kazne kojima se izražava ispunjenje proroštava iznesenih u Tori i knjigama židovskih proroka (težak izgon, uništenje Obećane zemlje te njezino opustošenje tijekom vremena egzila, ali i povratak izraelskog naroda u nju). Druga tema je ljubav i čežnja židovskog naroda za Cionom, gdje će autor pokazati kako su Biblija i duhovni vođe, rabini, pomogli olakšati bol naroda zbog izgona uvođenjem raznovrsnih blagdana, običaja i molitava kojima su osnažili kolektivno nacionalno pamćenje te održali nadu u okupljanje izgnanih, izgradnju Jeruzalema i Hrama te u dolazak Mesije. Posljednji dio članka obrađuje krize s kojima se židovski narod suočavao tijekom dugog i teškog puta do Ciona. Autor se u radu uz biblijske izvore služi i vrelima iz rabinske literature, od talmudskih vremena preko srednjega vijeka sve do modernog doba. Velik dio literature prvi je put na hrvatski s hebrejskoga i aramejskoga preveo upravo autor. - In this article the author analyses the special bond between the Jewish people and the Holy Land. The Jewish people emigrated numerous times during their permanent pilgrimage towards the “Promised Land”. These pilgrimages helped to build, form and maintain the Jewish national identity during the most difficult moments of the long Exile. The first part of the article consists of a general introduction, followed by the main descriptions of immigration and emigration in the history of the Jewish people. The central part of this article deals with two main issues: the first one is the Jewish theological importance of immigration and emigration of the Jews as a sign of Divine providence and the implementation of the idea of reward and punishment that expresses the fulfilment of the prophecies written in the Torah and the books of the Jewish Prophets about the harsh Exile, the destruction of the Promised Land and its barrenness during the time of the Exile, as well as the return of the people of Israel to the Promised Land. The second issue is the love and longing for Zion in the Jewish national collective, where the author shows how the Bible and the spiritual leaders, the Rabbis, helped the nation relieve the pain of the Exile by establishing different holidays, customs and prayers to strengthen the collective national memory and keep going the hope for the ingathering of the Exiles, the building of Jerusalem and the Temple and the coming of the Messiah. The last part of this article explores some of the crises, which the Jewish people faced on their long and hard way to Zion. In this paper, the author uses many sources from the rabbinical literature since Talmudic times through the middle Ages until modern times. Much of this literature is translated into Croatian from Hebrew and Aramaic for the first time by the author.

MATOŠEVIĆ, Andrea
"Čovjek je ujedno i ono što može biti" [Elektronička građa] : interpretacija značenja termina otuđenje u socijalizmu i postsocijalizmu / Andrea Matošević.
Bibliografske bilješke uz tekst ; bibliografija: str. 63-65. - Sažetak ; Summary. - U radu se analizira pojam otuđenja, odnosno alijenacije u dvostrukom smislu: s jedne strane kao značajna artikulacija filozofskih i socioloških problema u jugoslavenskoj socijalističkoj misli i šire, ali i istovremeno kao vrlo prisutna akcentuacija detektiranih stanja u industrijskim postrojenjima. Na toj dvostrukoj poziciji grade se djelomična analiza i usporedba s kontekstom današnjih uvjeta rada u sektoru koji Franco “Bifo” Berardi naziva “kognitarijatom”, ali iz kojega su detekcija i konstatacija otuđenja gotovo u potpunosti odstranjene i zamijenjene nizom supstituta poput “beznađa”, “ravnodušnosti”, “besperspektivnosti”, “samoizrabljivanja” ili pak “sagorijevanja na poslu”. U radu se interpretira nedostatnost takve zamjene, jer je otuđenje, unatoč konstantno naglašavanoj apstraktnosti njegova značenja, konotiralo kritiku, promjenu i nadilaženje trenutnog stanja, odnosno napor ka razotuđenju, što nije slučaj s nizom spomenutih termina. Iz tog je razloga rad prožet jezičnom analizom te pokušava odgovoriti na pitanje o mogućnosti govora i analize dijela današnjih, poglavito radnih, uvjeta i stanja u terminima otuđenja. - The paper analyses the notion of alienation in a dual sense: first, as a significant articulation of philosophical and sociological problems in Yugoslav socijalist thought and beyond, but also as a very present accentuation of the work conditions detected in industry. This double position builds a partial comparison with and analysis of the context of today’s working conditions in the “cognitariat” sector, but from which detection of alienation is almost completely removed and replaced with terms such as “hopelessness”, “indifference”, “futility”, “self-exploitation”, or “burnout”. The paper interprets the lack of such substitution, since alienation, despite the constantly emphasized abstractness of its meaning, connotes criticism, change and overcoming the current issues. This implies strong effort towards disalienation, which is not the case with the mentioned substitutive terms. For this reason, linguistic analysis and attempts to answer the question on the possibility of speaking and analysing a part of today’s, especially working, conditions in terms of alienation are a dominant part of this paper.

AKVANI, Hamdallah
A critical analysis of the political discourse of exceptionalism in the American Sniper movie [Elektronička građa] / Hamdallah Akvani, Abdolvahed Zarifi, Hossein Fakhraei. - Graf. prikazi.
Bibliografija: str. 40-42. - Summary ; Sažetak. - Political discourse usually tends to diffuse itself in other discursive fields. One of the areas through which the political field can be reproduced is the field of popular culture, especially films. Moreover, language serves as the intermediate variable in which political discourses in the media offer themselves more or less ideologically. In this paper, the language of the film American Sniper and its relation to the exceptionalism discourse in the politics of the United States is reviewed. It addresses the major question of how the discourse of American Sniper is related to the three layers of exceptionalism discourse. The analysis of the three discursive levels of description, interpretation and explanation of the film based on Fairclough’s model reveals that, by following Hollywood’s dominant framework of discourse towards Islam and the Middle East, i.e., the ‘Islamophobia’ discourse, the film depicts Islam as 'Other'. The discourse of the film ultimately resides in a wider social action that is congruous with the concept of the political language of exceptionalism. - Politički diskurs obično se širi kroz druga diskurzivna područja. Jedno od područja kroz koje se politika može reproducirati jest područje popularne kulture, posebno filma. Štoviše, jezik služi kao posredujuća varijabla kroz koju se politički diskursi predstavljaju u medijima, više ili manje ideološki. Ovaj rad analizira jezik filma Američki snajper i njegov odnos s diskursom izuzetnosti u politici SAD-a. Ključno pitanje koje rad postavlja jest kako je diskurs Američkog snajpera povezan s tri razine diskursa izuzetnosti. Analiza tri diskurzivne razine filma – deskripcije, interpretacije i objašnjenja – koje se temelje na Faircloughovu modelu, otkriva da film prati dominantni holivudski diskurs uokvirivanja islama i Srednjeg istoka, tzv. diskurs 'islamofobije' te prikazuje islam kao "drugog". Diskurs filma dio je šire društvene akcije koja je podudarna s konceptom političkog jezika izuzetnosti.

Aktualnost eseja jednog znanstvenika o fundamentalnim zakonima ljudske gluposti [Elektronička građa] / Vitomir Šunjić. - Ilustr., graf. prikazi.
Bibliografija: 13 jed. - Sažetak ; Summary. - Uz prikaz najzanimljivijih postavki svjetski poznatog eseja talijanskog znanstvenika Carla M. Cipolle "Fundamentalni zakoni ljudske gluposti", kojim se želi istaknuti svevremenost i široki značaj tog kratkog teksta, naveden je i niz primjera iz literature i aforizama na tu temu. Cipolla uvodi čitatelja u svoje razmatranje finom, ali i provokativnom ironijom. Njegov, po koncepciji jedinstven tekst zasniva se na pseudo-znanstvenoj analizi ljudskog društva koja je potkrijepljena fiktivnim eksperimentalnim rezultatima. Čitatelje iz naše znanstvene, tehničke ili poslovne sredine Cipollin tekst će sigurno iznenaditi, ali i zabaviti i potaknuti na razmišljanje. Njihova iskustva u brojnim prilikama i s određenim osobama vjerojatno će iskrsnuti u novom svijetlu te ih potaknuti da s prikladne distance promotre mnoga zbivanja koja su utjecala na njihov život i karijeru. - Along with the presentation of the most interesting aspects of the world-famous essay by C. M. Cipolla "The Basic Laws of Human Stupidity" with comments that emphasize actuality and high relevance of this text of the famous Italian scientists, selected examples from the literature and aphorisms related to this topic are also presented. Cipolla introduces the reader to his contemplation with a fine but provocative irony. His text, unique by construction, is based on pseudo-scientific analysis of human society, supported by fictive experimental results. For readers from our scientific, technical or entrepreneurial milieu, this text will surely represent a great surprise, but also entertainment and hint for reflection. Their former experience from many circumstances, and with specific persons, will probably appear in a new light, and push the readers to observe, from a proper distance, the many events that influenced their lives and carriers.

Doprinosi li dnevno vrijeme korištenja medija predviđanju obrazovnih aspiracija učenika na završetku osnovne škole [Elektronička građa] / Gordana Kuterovac Jagodić. - Graf. prikazi.
Bibliografija: str. 216-220. - Sažetak ; Summary. - Znatan dio dana adolescenti provode koristeći se suvremenim i tradicionalnim medijima i time su izloženi djelovanju tehnološkoga ekološkog podsustava koji prema razvojnoj teoriji ekoloških sustava može utjecati na različite aspekte njihova razvoja, uključujući i razvoj obrazovnih aspiracija. Cilj ovog istraživanja bio je utvrditi koliko vremena dnevno učenici osmog razreda osnovne škole provode na društvenim mrežama, videoigrama i u gledanju filmova, serija i videouradaka te utvrditi pridonose li te varijable, zajedno s individualnim varijablama roda i školskog uspjeha, obiteljskim varijablama roditeljskog obrazovanja, podrške i očekivanja te obrazovnim i medijskim resursima u kućanstvu, predviđanju učeničkih aspiracija prema gimnazijama ili strukovnim školama. Provjereno je i postoje li razlike u vremenu korištenja medija s obzirom na radni dan ili vikend, rod i obrazovne aspiracije. U istraživanju je sudjelovao 828 učenika osmog razreda zagrebačkih osnovnih škola. Sudionici su imali između 14 i 15 godina, a među njima je bilo 46.4% djevojčica. Podatci su prikupljeni od učenika upitnicima primijenjenima u školskom okružju. Uz različite medije adolescenti sa strukovnim aspiracijama provode u prosjeku 3 do 6 sati dnevno, a adolescenti s gimnazijskim aspiracijama otprilike 1.5 do 3 sata dnevno. Uz školski uspjeh, spol, socioekonomske i varijable percipirane roditeljske podrške i očekivanja, dnevno vrijeme korištenja medija pokazalo se značajnim ali slabim prediktorom obrazovnih aspiracija učenika na završetku osnovne škole. - Adolescents spend a sizeable amount of daily time using media, consequently exposing themselves to an ecological techno-subsystem which, according to the ecological systems theory, may influence several aspects of their development, including educational aspirations. This research aimed to determine daily screen time 8th-grade pupils spent on social media, video games, and films, TV-series and videos, and to find whether the screen times, in addition to individual variables of gender and school achievement, family variables of parental education, support, expectations and educational and media resources, add to the prediction of preference towards grammars school versus vocational education. Besides, differences in screen times with respect to gender, school preferences, and part of the week (working days or weekends) were examined. The participants were 828 pupils attending the finishing grade of elementary schools in Zagreb, Croatia. The participants’ age ranged from 14 to 15, and 46.4 % of them identified themselves as female. The data was collected using self-reported questionnaires administered during school classes. Adolescents who aspire towards vocational schools spend 3 to 6 hours on screen per day, while adolescents with aspirations towards higher secondary education spend 1.5 to 3 hours. In addition to the GPA, gender, socioeconomic variables, and perceived parental support and expectations, daily screen times on different media significantly add to the prediction of adolescents’ educational aspirations at the end of primary education. More screen time of playing video games and watching films, TV series, and videos predicts aspiration towards vocational education while more time spent on social media predicts aspiration towards higher secondary education, but only among girls.

The information - communication process in a business with outsourcing for the maintenance of a complex technical system [Elektronička građa] / Drago Kraljević, Krešimir Lacković, Robert Šojo. - Graf. prikazi.
Bibliografija: 17 jed. - Summary. - This paper discusses the process of communication between service providers and recipients when monitoring and maintaining complex technical systems. This requires sophisticated equipment, trained personnel and special methods and procedures. This is especially true for technical diagnostics, as the most complex form of monitoring and preventive maintenance. The relevant elements of maintenance by state and the experience of engaging an external partner are highlighted, especially when the complete monitoring for process control is performed virtually. In that sense, an information and communication process is proposed to ensure the efficiency of the complete system. The education of the external partner and the connection with the holders of external memories, research institutions and centres of excellence can be emphasized.

Inozemstvo, Zagreb ili neki drugi grad u Hrvatskoj? [Elektronička građa] : Društveno porijeklo, racionalnost izbora i aspiracije srednjoškolaca prema mjestu studiranja / Saša Puzić, Josip Šabić, Iva Odak. - Graf. prikazi.
Bilješke uz tekst. - Bibliografija: str. 304-307. - Sažetak ; Summary. - U radu se ispituju aspiracije hrvatskih srednjoškolaca kad je riječ o mjestu studiranja (inozemstvo, Zagreb, drugi grad u Hrvatskoj). Teorijsko polazište rada čini teorija racionalnog izbora, koja se koristi pri objašnjenju obrazovnih odluka u periodu obrazovnih tranzicija. Provedena je višerazinska multinomijalna regresijska analiza na nacionalno reprezentativnom uzorku učenika četverogodišnjih srednjih škola (N=10 829). Podatci su prikupljeni tijekom školske godine 2017./2018. Rezultati pokazuju da su aspiracije prema mjestu studiranja povezane s društvenim podrijetlom učenika: veće aspiracije prema studiranju u Zagrebu povezane su s visokoškolskim obrazovanjem barem jednog roditelja te s aktivnim radnim statusom majke i oca, dok su veće aspiracije za studiranjem u inozemstvu povezane s visokoškolskim obrazovanjem obaju roditelja i višim mjesečnim prihodima kućanstva. Učeničke aspiracije prema studiranju u inozemstvu povezane su i s čimbenicima racionalnog izbora: većom brigom za izbjegavanjem silazne društvene mobilnosti, višom samoprocjenom vjerojatnosti uspješnog upisa i završetka studija, nižom procjenom vrijednosti obrazovanja u hrvatskom društvu te višom procjenom nepoštovanja meritokratskih principa u hrvatskom visokom obrazovanju. S druge strane, aspiracije prema studiranju u Zagrebu od navedenih su čimbenika povezane samo s višom procjenom društvene vrijednosti obrazovanja. Svi su učinci bili neovisni o školskom uspjehu učenika. Dobiveni nalazi tumače se u kontekstu horizontalnih nejednakosti u visokom obrazovanju te se upućuje na moguće implikacije nalaza za obrazovnu politiku. - The paper examines the aspirations of Croatian secondary school students towards studying abroad, in Zagreb or in some other city in Croatia. The theoretical background of the paper was based on the rational choice theory, typically used in explaining educational decisions in periods of educational transition. A multi-level multinomial regression analysis was conducted using a nationally representative sample of students attending four-year secondary schools (N=10 829). The data were collected during the school year 2017/2018. The results indicate that aspirations towards the place of studying are related to the students’ social background: stronger aspirations towards studying in Zagreb correlate with having at least one parent with higher education and with the active working status of the mother and father, while stronger aspirations towards studying abroad correlate with the higher education of both parents and a higher monthly household income. Students’ aspirations towards studying abroad are also related to the rational choice indicators: greater concern with avoiding downward social mobility, higher estimate of the probability of successful enrolment at and completion of higher education, lower assessment of the value of education in Croatian society and higher assessment of non-compliance with principles of meritocracy in Croatian higher education. On the other hand, aspirations towards studying in Zagreb only correlate with a higher assessment of the social value of education. All effects were independent of the students’ school performance. The findings are interpreted in the context of horizontal inequalities in higher education, pointing to possible implications for the educational policy.

Is social entrepreneurship better for workers? [Elektronička građa] : The influence of work experience in Croatian social cooperatives on perceived well-being / Jelena Puđak, Dražen Šimleša. - Graf. prikazi.
Bibliografske bilješke uz tekst ; bibliografija: str. 27-29. - Summary ; Sažetak. - This paper aims to examine the motivations, values, and job satisfaction among the people employed in the sector of social entrepreneurship that were obtained through a qualitative study of ten Croatian social cooperatives. In our analysis, we interpreted the experiences of working in a social enterprise from the employee perspective. Our findings suggest that the participants/employees of social enterprises favour intrinsic motivation and values related to their jobs, that they describe their working conditions in social enterprises positively, and that they share a perceived increase in the quality of life since having started working at a social enterprise. The described relations between motivation, job experiences, and participatory management allowed us to build upon and extend the existing body of research on motivation and job satisfaction in the social economy sector. - Osnovna je namjera ovoga rada istražiti motivacije, vrijednosti i zadovoljstvo na radnome mjestu radnika zaposlenih u sektoru društvenog poduzetništva. Kvalitativnim istraživanjem obuhvatili smo deset socijalnih zadruga kako bismo interpretirali iskustva rada u društvenom poduzetništvu iz perspektive samih radnika. Iz rezultata istraživanja može se zaključiti kako sugovornici/radnici u društvenim poduzećima daju prednost intrinzičnoj motivaciji i intrinzičnim vrijednostima vezanim uz radno mjesto, pozitivno opisuju uvjete rada u društvenom poduzetništvu te dijele percepciju porasta kvalitete života otkad rade u društvenom poduzeću. Veze koje smo opisali u istraživanju između motivacija, radnog iskustva i participatornog upravljanja omogućuju proširenje postojećih zaključaka istraživanja motivacija i zadovojstva na radu u sektoru društvene ekonomije.

Komercijalni FM radio u kontekstu hrvatske medijske politike [Elektronička građa] / Marina Mučalo. - Graf. prikazi.
Bilješke uz tekst. - Bibliografija: str. 101-102. - Sažetak ; Summary. - Komercijalni privatni radiji dominiraju hrvatskim radijskim krajolikom. Razvijali su se od sredine 90-ih godina, od čega se posljednjih 15 godina sustavno financiraju javnim sredstvima iz Fonda za poticanje pluralizma i raznovrsnosti elektroničkih medija. Rad problematizira hrvatsku medijsku politiku koja je proteklih godina u cijelosti zanemarila razvoj neprofitne i javne radiodifuzije, prepuštajući medijski razvoj zemlje tržišnim instrumentima i komercijalnim sadržajima. Recentna istraživanja pokazuju da se ta vrsta radijskih programa doživljava kao jednolična glazbena kulisa koja gubi povjerenje slušatelja. Rad otvara pitanje daljnjeg razvoja hrvatskoga medijskog sustava pri čemu istaknutu ulogu imaju institucije koje su odgovorne za njegovo oblikovanje. - Commercial private radios dominate the Croatian radio landscape. They have been evolving since the mid-1990s. In the last fifteen years they have been systematically financed by public funding, namely by the Fund for the Promotion of Pluralism and Diversity of Electronic Media. This paper problematizes Croatia’s media policy, which, in the recent years, has completely neglected the development of non-profit and public service broadcasting, leaving the country’s media development with market instruments and commercial content. Recent research shows that this type of radio is perceived as a monotonous musical scenery that loses listeners’ trust. The paper raises a question of further development of the Croatian media system, with a prominent role for the institutions responsible for shaping it.

Bibliografska bilješka uz tekst ; bibliografija: str. 90-92. - Sažetak ; Summary. - Ovaj rad predstavlja komparativnu studiju sačinjenu od četiri istraživanja obavljena u periodu od 1997. do 2015. godine. U njima se ispituje konotativno značenje politički relevantnih pojmova kod učenika završnih razreda raznih vrsta srednjih škola. Kako je konotativno značenje ono dodatno, emocionalno obojeno značenje, ta obojenost potiče iz socijalne sredine i duha vremena, te je sa promenama ovoga značenja moguće pratiti i promene dominantnih društvenih vrednosti i društvene klime. Uzorak je činilo ukupno oko 750 učenika koji su u četiri vremenske tačke (poduzorci su u tim tačkama bili ujednačeni po socijalno-demografskim karakteristikama) procenjivali sledeće pojmove: nacija, nacionalizam, socijalizam, vođa, demokratija, mir, levica, desnica, sadašnjost i budućnost. Svaki od pojmova ispitan je Ozgudovom skalom semantičkog diferencijala preko 12 opozitnih parova prideva poput ružan-lep ili bezvredan- vredan. Rezultati su pokazali značajna variranja kako na 12 pridevskih parova na svakom pojmu u jednoj vremenskoj tački – što daje suptilniji profil značenja nego što bi dala opšta, jedinstvena ocena pojmova poput demokratije ili nacije – tako i u četiri vremenske tačke. Variranja tokom godina daju indicije o promeni društvene klime i vrednosti, barem u generaciji mladih, u ovom po Srbiju turbulentnom razdoblju od dve decenije. - This paper is a comparative study composed of four studies conducted between 1997 and 2015. The authors examine the connotative meaning of politically relevant concepts in 18-19 years old students from various types of secondary schools. The connotative meaning is an additional, emotionally colored meaning of words, and this coloration originates from the social environment and the spirit of the times. Therefore, with the changes of this meaning it is possible to follow the changes of dominant social values and social climate. The sample consisted of a total of 750 students assessing the following concepts, at four time points (sub-samples at these points were balanced in terms of socio-demographic characteristics): nation, nationalism, socialism, leader, democracy, peace, left, right, present and future. Each of the concepts is examined by Ozgud’s scale of semantic differential, through 12 opposing pairs of adjectives like bad – good or worthless – worthy. The results showed considerable variation in both: 12 adjective pairs on each single concept at a single point in time – giving a more subtle profile of meaning than in case of a general assessment of the concepts – and over time. The variations over the years give indications of a change in social climate and values, at least in the generation of young people, in these turbulent two decades in Serbia.

Konstrukcija i validacija Skale vjerom inspiriranoga društvenog angažmana (VIDA) među mladima u Hrvatskoj [Elektronička građa] / Ivan Landripet, Goran Koletić, Luka Jurković, Siniša Zrinščak, Aleksandar Štulhofer. - Graf. prikazi.
Bibliografske bilješke uz tekst ; bibliografija: str. 430-433. - Sažetak ; Summary. - Diljem svijeta vjerske zajednice i laička vjerski orijentirana udruženja potiču vjernike, osobito mlade, na aktivan angažman u promicanju i zaštiti religijskih vrijednosti. U Hrvatskoj se vjerski društveni angažman promovira i prakticira već desetljećima, no taj je iskaz religioznosti ostao posve neistraženim. U svrhu stvaranja pretpostavki za izučavanje raširenosti, oblika, pozadine i učinaka takve vjerske prakse, u radu se predstavlja izrada i metrijska provjera Skale vjerom inspiriranoga društvenog angažmana (VIDA). U kvalitativnome dijelu istraživanja kreirano je 16 indikatora konceptualno predviđenih dimenzija humanitarnoga, evangelizacijskog, građanskog i političkoga društvenog angažmana. Anketni, evaluacijski, dio istraživanja proveden je na slučajnom uzorku mladih u dobi od 18 do 25 godina (N = 552), selektiranih iz velikoga nacionalnog internetskog panela. Struktura i spolna invarijatnost VIDA-e provjerena je konfirmacijskom faktorskom analizom, a valjanost njezinim povezivanjem s drugim mjerama religioznosti te srodnim stavovskim i vrijednosnim obilježjima. Za cjelinu i podskale VIDA-e analizama je demonstrirana kriterijska, konstruktna i diskriminacijska valjanost, visoka interna konzistentnost, dobro pristajanje latentne strukture podacima te podjednaka primjenjivost na mlade muškarce i žene u Hrvatskoj. Na kraju rada kratko se raspravlja o ograničenjima i mogućnostima uporabe nove mjere. - Globally, religious institutions and faith-based civic associations are encouraging believers, particularly young people, to actively advocate and defend religious values. While in Croatia religious social engagement has been promoted and practised for decades, this form of religiosity remained unexplored. To facilitate research on the prevalence, background, types, and outcomes of such collective activity, this paper presents the construction and evaluation of a faith-based social engagement scale. Based on qualitative methods, 16 items indicating four dimensions of faith-based engagement (humanitarian, evangelical, civic, and political) were confirmatory factor analysed in a probability sample of emerging adults, aged 18–25 years (N = 552), selected from a commercial online panel. The scale’s validity was confirmed by associations with other measures of religiosity and religiosity-related attitudes and values. In addition to the satisfactory criterion, construct, and discriminative validity, the scale was gender-invariant and had high internal consistency. The conclusion features a brief discussion of limitations and a range of potential applications of this new measure.

Kritički osvrt na konceptualne i metodološke probleme u istraživanjima evolucije socijalne kognicije na primjeru kooperativnoga rješavanja problema [Elektronička građa] / Ljerka Ostojić.
Bibliografija: str. 621-629. - Sažetak ; Summary. - Jedno je od glavnih istraživačkih područja u socijalnoj kogniciji životinja kooperativno rješavanje problema, tj. kognicija kod međusobne suradnje životinja. Smatra se da je socijalna kognicija evoluirala zbog zahtjeva koje donosi život u grupama i često se drži adaptacijom za takav život. Analiza socijalnoga učenja, drugoga istraživačkog područja unutar socijalne kognicije, pokazala je da je ta pretpostavka u literaturi prouzročila dva problema. Prvo, postoji pristranost prema testiranju socijalnih vrsta, i drugo, postoji a priori pretpostavka da je socijalno učenje kvalitativno drugačije od individualnoga. Ta dva problema nisu nužno ograničena na socijalno učenje, nego mogu biti prisutna i u drugim poljima unutar istraživanja socijalne kognicije. Primjena slične analize na kooperativno rješavanje problema ukazuje da i u tome području postoje oba problema. Prvo, empirijska se istraživanja provode ponajprije na vrstama koje su socijalne i na onima koje pokazuju kooperativna ponašanja u divljini. Drugo, pretpostavka da se kooperativno rješavanje problema temelji na specifično socijalnim kognitivnim sposobnostima implicirana je u velikome dijelu literature. Moguće je da je to rezultat miješanja različitih komponenti unutar kognitivnoga procesa: koja je informacija potrebna za uspješnu kooperaciju i kako se ta informacija stječe. Dok prva komponenta mora uključivati informaciju o drugome pojedincu, ne postoji indikacija da se druga komponenta mora razlikovati od već poznatih, općenamjenskih mehanizama. Ta dva problema sprečavaju sistematsko ispitivanje razlika između vrsta i ometaju istraživanje evolucije kooperativnoga rješavanja problema. - A major research area in non-human social cognition is the investigation of cooperative problem-solving, i.e. the cognition involved in situations when animals cooperate with each other. Social cognition is thought to have evolved due to the demands of social living and is often thought to present an adaptive specialisation for living in groups. A previous analysis of social learning, another area of social cognition, has highlighted how this has consequently led to two overarching biases in the literature: firstly, a bias towards testing only social species, and secondly, an a priori assumption that social learning is qualitatively different from learning involved in non-social situations. The problem of these biases may not be restricted only to social learning but it may also be present in other areas of social cognition research. Applying an equivalent analysis to cooperative problem-solving shows that here too both biases are present. Firstly, empirical studies on cooperative problem-solving were primarily conducted with social species and species that exhibit cooperative behaviours in the wild. Secondly, the assumption that cooperative problem-solving relies on a distinctly social cognitive ability can, at least implicitly, be observed throughout the literature. This may be the result of confounding different components of the cognitive process involved in cooperation: what information is required to successfully cooperate and how this information is acquired. While the former needs to involve information about another individual, there is no indication that the latter is required to differ from any known, domain-general cognitive mechanism. These two biases make it difficult to systematically test whether and how cooperation differs between species, and as such impede investigations into the evolution of cooperative problem-solving.

Media coverage of different scientific disciplines in the Croatian daily press [Elektronička građa] : socio-historical perspective / Adrijana Šuljok. - Graf. prikazi.
Bibliografske bilješke uz tekst ; bibliografija: str. 62-64. - Summary ; Sažetak. - The goal of this research was to determine the changes in frequency and characteristics of media reporting of different scientific disciplines in the socio-historical context in which they arise. The research was conducted using the method of content analysis, which comprised Croatian daily newspapers with the highest readership in two time periods: ’socialism‘, from 1986 to 1988, and ’democracy‘, from 2006 to 2008. The constructed week method was used to select a total of 885 articles. The findings confirm the specificities in media communication of particular scientific disciplines in different socio-political contexts, as well as a tendency of levelling media practices in line with global trends, such as growing orientation towards medicalisation and socio-spatial domination of 'Western' news. - Cilj ovog istraživanja bio je utvrditi promjene u učestalosti i obilježjima medijskog izvještavanja o različitim znanstvenim disciplinama u društveno-povijesnom kontekstu u kojem nastaju. Istraživanje je provedeno metodom analize sadržaja koja je obuhvatila najčitanije hrvatske dnevne novine u dva vremenska razdoblja: „socijalističkom“, od 1986. do 1988., i „demokratskom“, od 2006. do 2008. Korištena je metoda konstruiranog tjedna za odabir ukupno 885 članaka. Nalazi potvrđuju specifičnosti medijske komunikacije pojedinih znanstvenih disciplina u različitim društveno-političkim kontekstima, kao i tendenciju ujednačavanja medijskih praksi u skladu s globalnim trendovima, kao što su rastuća orijentacija prema medikalizaciji i socioprostorna dominacija "zapadnjačkih" vijesti.

Međuvršnjački prijateljski odnosi u razrednom odjelu [Elektronička građa] / Ante Kolak, Ivan Markić. - Graf. prikazi.
Bibliografija: str. 125-128. - Sažetak ; Summary. - Ovaj rad usmjeren je na proučavanje prijateljskih odnosa unutar razrednog odjela. Odnosi među vršnjacima izuzetno su važni u školskom razdoblju, a nedostatak ili trajne teškoće u prijateljskim odnosima mogu se reflektirati na uspjeh učenika, usvajanje nastavnih sadržaja, sliku učenika o sebi, socijalni status i socijalni uspjeh itd. Cilj empirijskog dijela rada je ispitati kvalitetu prijateljskih odnosa unutar razrednog odjela u kategoriji ‘najbolji prijatelj’. Iz cilja istraživanja proizašla su tri istraživačka pitanja: Kakav je profil prijateljskih odnosa u kategoriji ‘najbolji prijatelj’? Kako izgleda hijerarhijska struktura dimenzija kvalitete prijateljstva u ponuđenim kategorijama? Koje karakteristike opisuju najboljeg prijatelja i idealnog prijatelja? Rezultati istraživanja utvrđuju dva profila: opći te profil blizine i roditeljske uključenosti. Utvrđivanje hijerarhijske strukture ukazalo je na važnost brige i priznanja (dječaci) te pouzdanosti i rješavanja problema (djevojčice). Vrh hijerarhijske ljestvice zauzimaju dimenzije priznanja i pouzdanosti. Kao najznačajnije karakteristike koje opisuju najboljeg prijatelja ističu se razgovor i zajedničko provođenje vremena, povjeravanje i pomoć, a u idealnom prijateljstvu izdvajaju se moralne vrijednosti prijatelja. - This paper focuses on studying friend relationships in the classroom. Relationships between peers are exceptionally important in school age, and a lack of such relationships or continued difficulties with them can reflect on student successes, learning outcomes, and student perceptions of self, social status, social success, etc. The goal of the empirical part of the research was to examine the quality of friend relationships within the classroom in the category of ‘best friend’. Three research questions arose from the research goal: What is the profile of friend relationships in the category of ‘best friend’? What is the hierarchical structure of the quality dimensions of friendship in the categories offered? Which characteristics describe one’s best friend and the ideal friend? The results of research affirm two profiles – a general one, and the profile of closeness and parental involvement. The affirmation of hierarchical structure pointed to the importance of care and recognition (among boys) and reliability and problem solving (among girls). The highest point in the hierarchy is held by the dimensions of recognition and reliability. The most significant characteristics that describe one’s best friend include conversation and spending time together, trust and aid; the moral values of the friend are exemplified in an ideal friendship.

Mobilizacijska struktura veteranskog pokreta u Hrvatskoj [Elektronička građa] : organizacije društvenog pokreta i članstvo / Dragan Bagić, Kruno Kardov, Mislav Škacan. - Graf. prikazi.
Bibliografske bilješke uz tekst ; bibliografija: str. 219-222. - Sažetak ; Summary. - Cilj rada je istražiti dinamiku udruživanja hrvatskih ratnih veterana te ustanoviti ključna obilježja koja doprinose članstvu u veteranskim organizacijama. Analiziraju se podaci veteranskih organizacija iz Registra udruga RH za razdoblje od 1991. do 2014. godine te podaci o socio-demografskim karakteristikama, veteranskom identitetu i političkim preferencijama članova veteranskih organizacija prikupljeni anketnim istraživanjem 2015. godine. Rezultati pokazuju da je članstvo veteranskih organizacija određeno ratnim iskustvom, socio-demografskim te političkim obilježjima. Veteranske organizacije su dominantno mjesnog karaktera, a ključne interne razlike u udruživanju određene su posljedicama rata i načinom ulaska u rat. Zabilježene su značajne razlike između članova i ne-članova veteranskih organizacija u smislu da su članovi u većoj mjeri orijentirani prema desnom političkom spektru, što pokazuje da u određenim prilikama veteranske organizacije mogu značajno usmjeravati kolektivno djelovanje ratnih veterana u političkoj areni. U radu se raspravljaju uvidi o asocijacijskoj gustoći veterana, razlike između članova i ne-članova veteranskih organizacija te obrasci i ciklusi veteranskog udruživanja. - The paper explores organizing dynamics of Croatian war veterans and the key attributes of membership in veterans’ organizations. We use data from the Register of associations of the Republic of Croatia for the period 1991-2014, as well as data from 2015 survey research on sociodemographic profile, veterans’ identity and political preferences of members of veterans’ organizations. The results show that membership of veterans’ organizations is determined by the war experience, socio-demographic and political factors. Veterans’ organizations are predominantly local in nature, and the key internal divisions are based on victimization and the status of volunteer. Members and non-members of veterans’ organizations significantly differ in political orientations. Members of war veterans organizations are more oriented towards the right side of the political spectrum, indicating that on certain occasions veterans’ organizations could direct the collective action of war veterans in support of right-wing political parties and candidates in the political arena. The paper discusses insights on associational density, differences between members and non-members of veterans’ organizations as well as patterns and cycles of veterans’ organizing.

Modernizacija urbanoga života u Hrvatskoj kroz prizmu stambenih i komunalnih politika u razdoblju socijalizma [Elektronička građa] / Mario Bara. - Graf. prikazi.
Bibliografske bilješke uz tekst ; bibliografija i izvori: str. 28-32. - Sažetak ; Summary. - U članku se upućuje na važnost nekih aspekata polustoljetne modernizacije u Hrvatskoj (1945. – 1990.) koja je donijela industrijsku transformaciju države i promjenu strukture stanovništva. Cilj je pokazati utjecaj javnih politika, tj. racionalizacije odlučivanja na primjerima modernizacijskih procesa u stambenim i komunalnim politikama. Paternalistička uloga države s jasnim nedostatkom pluralnosti bila je vidljiva u svakom segmentu gospodarskoga, političkoga i društvenoga života. Mjere za brzu gospodarsku i socijalnu transformaciju društva započele su još tijekom rata. Velike državne intervencije bile su naglašene u industrijalizaciji i urbanizaciji, koje su pratile migracije radne snage iz ruralnih u urbana područja. Zbog velikoga broja novih stanovnika gradova vlasti su posvećivale veliku pozornost stambenim i komunalnim politikama. Istovremeno ovaj rad smjera upozoriti na segmente političkoga odlučivanja koji do sada nisu bili promatrani kroz dimenziju javnih politika na primjeru nekih aspekata modernizacije urbanoga života u Hrvatskoj. U zaključku se upućuje na mogući interdisciplinarni okvir istraživanja problema javnih politika u povijesnoj dimenziji. - This article points to the importance of several aspects of the 50 year-long modernisation process that brought industrial transformation and changes to the population structure in Croatia. The aim is to bring attention to the influence public policies (with their rationalised decision-making) had on this process using example cases of modernisation processes in housing and communal policies. The paternalistic role of the state, with its clear absence of plurality, became visible in every segment of economic, political, and social life. Due to the increased inflow of residents to the cities, the government paid great attention to housing and communal policies. The first measures for the rapid economic and social transformation of society came into effect early on, during the war period. Major state interventions were emphasised through industrialisation and urbanisation, which followed worker migrations from rural to urban areas. This paper also aims to warn about specific segments of political decision-making that have so far not been studied through the dimension of public policies, using the examples of some aspects of the modernisation of urban life in Croatia. In conclusion, the paper points to a possible interdisciplinary framework for research on the issue of public policies through a historical dimension.

Relacijske rodne strategije u podjeli kućanskih poslova [Elektronička građa] = Relational gender strategies in the division of household labour / Augustin Derado, Mirko Petrić, Inga Tomić-Koludrović.
Bilješke uz tekst. - Tekst usporedno na hrv. i engl. jeziku. - Bibliografija: str. 348-350. - Sažetak ; Summary. - U članku se iznose rezultati kvalitativnog istraživanja rodne podjele kućanskih poslova u Hrvatskoj, u širem okviru ukupnih radnih praksi kućanstava (tj. ukupnoga plaćenog i neplaćenog rada koji pridonosi ostvarivanju njihovih ciljeva). Podatci su prikupljeni kroz 92 polustrukturirana intervjua (34 s muškarcima, 43 sa ženama i 15 partnerskih), provedena u svim hrvatskim regijama, uz visok stupanj varijacije po sociodemografskim obilježjima. Primijenjena je relacijska rodna analiza, čiji je teorijski okvir počivao ponajprije na Bourdieuovu prakseološkom pristupu konceptu strategije, kao i na Pahlovoj konceptualizaciji ukupnog rada kućanstva, te analizi rodne dimenzije strategija kod Hochschild. Procesi kategorizacije uključivali su tri razine kodiranja (referentno, otvoreno i selektivno), a procesi povezivanja izradu analitičkih profila i tablica. Identificirane individualne rodne strategije povezane s obavljanjem kućanskih poslova jesu: strategije neupitnosti, otpora promjeni, suradnje, te proaktivne egalitarnosti (kod muškaraca) i strategije neupitnosti, pritiska, pristajanja, te proaktivne egalitarnosti (kod žena). Dovođenjem u odnos navedenih muških i ženskih individualnih strategija, uz primjenu kriterija rodne ravnoteže, dobivena je sljedeća tipologija strategija kućanstava u Hrvatskoj s obzirom na podjelu kućanskih poslova: neupitno tradicionalna, pretežno tradicionalna, početno egalitarna i proaktivno egalitarna. U dijelu muških i ženskih individualnih strategija pojavljuje se i komponenta opravdavanja u podjeli kućanskih poslova. Teorijski je doprinos analize primjena Bourdieuova prakseološkog pristupa strategijama u relacijskom istraživanju roda. - The article presents the results of a qualitative inquiry into the gender division of household labour in Croatia, in the wider context of the total work practices of a household (i.e., total paid and unpaid work contributing to the realisation of its goals). The data were gathered through 92 semi-structured interviews (34 with men, 43 with women, and 15 with partners), carried out in all Croatian regions, with a high degree of variation in socio-demographic characteristics. Relational gender analysis was applied, the theoretical framework of which rested primarily on Bourdieu’s praxeological approach to the concept of strategy, as well as on Pahl’s conceptualisation of total work of the household and Hochschild’s analysis of the gender dimension of strategies. Categorisation processes included three levels of coding (referential, open, and selective) while linking processes included the construction of analytical profiles and tables. The individual gender strategies identified relating to the performance of household labour are the strategies of unquestionability, resistance to change, cooperation, and proactive egalitarianism (for men), and the strategies of unquestionability, pressure, acceptance and proactive egalitarianism (for women). Bringing into relation the afore-mentioned male and female individual gender strategies and applying the criterion of gender balance resulted in the following typology of the household strategies related to the division of household labour: unquestionably traditional, predominantly traditional, initially egalitarian, and proactively egalitarian. The component of justification concerning the division of household labour appears partially in both male and female individual strategies. The theoretical contribution of the analysis lies with the application of Bourdieu’s praxeological approach to strategies in relational gender research.

Resources and strategies used by young parents in Serbia [Elektronička građa] / Dragan Stanojević, Smiljka Tomanović, Milana Ljubičić. - Graf. prikazi.
Bibliografske bilješke uz tekst ; bibliografija: str. 377-379. - Summary ; Sažetak. - The paper deals with resources available to young parents and the strategies they deploy as a response to various domain-related demands (housing, finance, work, family). First, the structural and cultural features of the social context in Serbia are discussed as the framework for the study. Secondly, the paper analyses young parents’ differences, by socioeconomic status (SES) and gender, regarding their resources, such as housing, finances, and employment, as well as their strategies. The analysis is based on a mixed-methods approach, which brings together the survey results of a sub-sample of 435 parents from a nationally representative survey of young adults aged 18 to 35, and a qualitative analysis of semi-structured interviews with 24 young mothers and fathers. The analyses indicate significant SES and gender differences in young parents’ resources and strategies, which are shaped by the structures and cultures of parenthood specific to the contemporary social context in Serbia. - Predmet ovog članka su resursi i strategije koje mladi roditelji koriste kao odgovore na zahtjeve koji dolaze iz različitih domena (stanovanja, financija, rada i obitelji). Strukturne i kulturne karakteristike društvenog konteksta Srbije čine okvir unutar kojega je smješten predmet istraživanja. Zatim su analizirane razlike među mladim roditeljima koje se tiču resursa poput stanovanja, zaposlenja kao i njihove strategije, imajući u vidu njihov socioekonomski status (SES) i rod. Analiza je temeljena na kombiniranim metodama koje uključuju rezultate anketnog istraživanja mladih u dobi od 18 do 35 godina, kao i kvalitativnu analizu polustrukturiranih intervjua provedenih s 24 mladih očeva i majki. Analize upućuju na značajne SES i rodne razlike mladih roditelja u pogledu resursa kojima raspolažu i strategija kojima se koriste, a koje su oblikovane društvenim strukturama i kulturom roditeljstva specifičnom za suvremeno društvo Srbije.

Rješavanje konflikata kao poduzetnička kompetencija [Elektronička građa] : osvrt na srednjoškolsku populaciju i ulogu stručnih suradnika / Krešimir Dabo, Rosanda Lovrić. - Graf. prikazi.
Bibliografija: 16 jed. - Sažetak ; Summary. - Konflikt između učenika kao mogući početak krizne situacije u školi dio je školskog procesa i s njim se redovito susreću nastavnici i stručni suradnici. Međutim, konflikt, iako može izazvati krizu, s druge strane, otvara mogućnosti za uspostavljanje bolje i adekvatnije komunikacije među učenicima i stvara prostor za učenje o nenasilnom komuniciranju, medijaciji kao formi rješavanja sukoba te asertivnom zastupanju svojih stavova i uvjerenja, što dugoročno vodi ka jačanju i poduzetničkih kompetencija. Iako se neki vršnjački konflikti zadržavaju samo na razini učenika i eventualno nastavnika u razredu, kada sukobi eskaliraju redovito se traži pomoć stručnih suradnika u školi poput psihologa ili pedagoga. Kakva je komunikacijska uloga tih profesionalaca u procesu medijacije između učenika, kojim tehnikama se oni služe u svom savjetodavnom radu, primjećuju li pomake ili promjene u ponašanju učenika nakon provedene medijacije, što se u njihovoj praksi pokazuje kao najuspješnija metoda svladavanja i razumijevanja konflikta, dio je ispitivanja ovoga rada kroz dubinske intervjue. S druge strane, rad analizira i percepciju učenika kroz anketni upitnik. Javljaju li se stručnim suradnicima za pomoć, kako rješavaju i upravljaju svojim konfliktima, što im je potrebno da prevladaju sukob, te razvijaju li svoje poduzetničke kompetencije, neka su od problemskih pitanja ovoga rada. U nastojanju da se prepoznaju kapaciteti savjetodavnoga rada i uloge medijacije stručnih suradnika u vršnjačkim sukobima u školi, za istraživačku analizu odabrana je Srednja škola Metković, s ciljem determiniranja uloge pedagoga i psihologa u kriznoj situaciji rješavanja učeničkih konflikata kroz primjer iz prakse. - Conflict between students, as a possible beginning of a crisis situation at school, is an integral part of the school process and is regularly encountered by teachers and professional associates. However, conflict, although it can cause a crisis, opens up opportunities for establishing better and more adequate communication among students as much as it creates space for learning about nonviolent communication, mediation as a form of conflict resolution and assertive representation of their attitudes, beliefs and entrepreneurial competencies. Although some peer conflicts persist only at the student level and possibly teachers in the classroom, when conflicts escalate, the aid from professional school associates such as psychologists or pedagogues is regularly sought. What is the communication role of these professionals in the process of mediation between students, what techniques they use in their counseling work, whether they notice changes in student behavior after mediation, which in their practice proves to be the most successful method of overcoming and understanding conflict - the paper examines all these aspects through in-depth interviews. On the other hand, the paper also analyzes students' perception through a survey questionnaire. Whether they turn to professional associates for help, how they resolve and manage their conflicts, what they need to overcome conflict, and whether they develop their entrepreneurial competencies are some of the problematic issues of this paper. In an effort to identify the capacity of counseling and the role of mediation of professional associates in peer conflicts at school, Metković High School was selected for research analysis, with the aim of determining the role of pedagogues and psychologists in critical situations of student conflicts through practical examples.

RISTIĆ Dedić, Zrinka
Roditeljske srednjoškolske aspiracije za djecu iz perspektive učenika pri kraju osnovnog obrazovanja [Elektronička građa] = Parental aspirations for their children's secondary education from the perspective of pupils at the end of elementary education / Zrinka Ristić Dedić, Boris Jokić. - Graf. prikazi.
Bilješka uz tekst. - Tekst usporedno na hrv. i engl. jeziku. - Bibliografija: str. 185-187. - Sažetak ; Summary. - Roditeljske srednjoškolske aspiracije su ambicije i ciljevi koje roditelji imaju za svoju djecu u vezi s obrazovanjem na srednjoškolskoj razini. U hrvatskom kontekstu dosad nisu bile istraživane iako značajno pridonose učeničkim aspiracijama i školskom uspjehu, a prediktor su i pokazatelja uključenosti roditelja u obrazovanje djece. Cilj je ovog rada istražiti prirodu i odrednice roditeljskih srednjoškolskih aspiracija iz perspektive učenika te opisati obrasce komunikacije i interakcije roditelja i djece vezano uz aspiracije i prijelaz iz osnovne u srednju školu. Roditeljske srednjoškolske aspiracije ispitane su iz perspektive učenika istraživanjem miješanog modela, koje je uključivalo upitničko ispitivanje s 1 031 učenikom 8. razreda zagrebačkih osnovnih škola te provedbu polustrukturiranih razgovora s 29 učenika na kraju prvog polugodišta 8. razreda. Kvantitativna istraživačka dionica pokazuje da su značajni prediktori roditeljskih srednjoškolskih aspiracija očekivani školski uspjeh učenika i obrazovni status roditelja, dok učinak spola učenika nije značajan. Kvalitativna istraživačka dionica upućuje na podudarnost učeničkih i roditeljskih aspiracija te na znatnu uključenost roditelja u proces odabira srednjoškolskih opcija. U obiteljima različitoga obrazovnog statusa roditelja utvrđeni su ponešto različiti komunikacijski i interakcijski obrasci vezano uz srednjoškolske aspiracije i odabir srednje škole, koji se vežu uz razlike u vrednovanju gimnazijskog i strukovnog obrazovanja u tim obiteljima. - Parental secondary educational aspirations are the ambitions and goals that parents have for their children's secondary education. In the Croatian context, they have not been researched so far, despite contributing significantly to pupils' aspirations and school success and being a predictor of parental involvement in children's education. This paper aims to research the nature and determinants of parental secondary educational aspirations from the perspective of pupils and describe the patterns of communication and interaction between parents and children related to aspirations and the transition from elementary to secondary school. Parental secondary educational aspirations were examined from the pupils' perspective by a mixed-model study involving a survey of 1,031 8th-grade pupils from elementary schools in Zagreb and semi-structured interviews with 29 pupils at the end of the first semester of the 8th grade. The quantitative part of the research indicates that pupils' expected school achievement and parental educational status were significant predictors of parental secondary educational aspirations, while the effect of pupils' gender was not significant. The qualitative part of the research points to a congruence between pupils' and parental aspirations and the substantial involvement of parents in the process of selection of secondary educational options. In families where parents have different educational statuses, the patterns of communication and interaction regarding aspirations and secondary school choice varied to some extent and were related to different valuation of grammar schools and vocational education in these families.

BERTIĆ, Želimir
Self-assessment of social and family loneliness in elderly during COVID-19 pandemic in relation to current level and type of communication intensity [Elektronička građa] / Želimir Bertić, Mirjana Telebuh. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - Due to the spread of coronavirus people throughout the world, many countries, Croatia included, have been forced to impose social distancing resulting in an increased number of people at risk of another public health problem – loneliness. Loneliness can be defined as the presence of negative emotions associated with the perceived social exclusion and is identified as one of the major issues of the aging population. There is a relatively small number of studies either dealing with the use of various communication methods, particularly information and communication technologies, by the elderly during the COVID-19 pandemic or determining potential benefits of such activities. The aim of this research was to determine the difference in self-assessment of social and family loneliness according to the means of communication used by the elderly during the COVID-19 pandemic. The research was conducted in March and April 2020 covering the period from the introduction of the epidemiological measures of social distancing and self-isolation until the relaxation of virus-related restrictions in Croatia. The research included 107 subjects over the age of 65 living in their own homes in the Croatian city of Bjelovar. A Frequency of the Used Communication Methods Questionnaire was constructed for the purpose of this research. The Social and Emotional Loneliness Scale for Adults was used to determine the level of loneliness. The obtained results indicate that lower levels of social and family loneliness were shown by subjects who stated in their self-assessment a higher intensity level of communication during the COVID-19 pandemic, such as making telephone/mobile phone calls, using information technology (computers for video calls, social networks, etc.) and mobile chat applications (Viber, Skype, WhatsApp, etc.), as well as having face-to-face communication. - Zbog širenja korona virusa ljudi diljem svijeta pa tako i u Hrvatskoj prisiljeni su na socijalno distanciranje čime raste broj osoba koje ulaze u rizik još jednog javnozdravstvenog problema, a to je usamljenost. Usamljenost se može definirati kao stanje prisutnosti negativnih osjećaja povezanih s percipiranom socijalnom izolacijom, te se navodi kao jedan od najizraženijih problema starenja. Relativno je malen broj istraživanja koja se bave korištenjem različitih metoda komuniciranja, posebice informacijsko komunikacijskih tehnologija kod starijih osoba tijekom pandemije COVID-19 i utvrđivanja eventualne dobiti koja bi ta aktivnost imala. Cilj ovog istraživanja bio je utvrditi razliku u samoprocjeni socijalne i obiteljske usamljenosti prema načinu komunikacije kod starijih osoba tijekom pandemije COVID-19. Istraživanje je provedeno u ožujku i travnju 2020. godine, točnije u periodu od uvođenja epidemioloških mjera socijalnog distanciranja i samoizolacije do perioda popuštanja mjera u suzbijanju širenja korona virusa u Hrvatskoj. U istraživanju je sudjelovalo 107 ispitanika starosti višoj od 65 godina koji žive u vlastitom kućanstvu na području Bjelovara. Za potrebe istraživanja je konstruiran Indeks o učestalosti načina komunikacije. Za provjeru razine usamljenosti korištena je Skala socijalne i emocionalne usamljenosti. Dobiveni rezultati ukazuju da manju socijalnu i obiteljsku usamljenost pokazuju ispitanici koji samoprocjenjuju višu razinu komunikacije tijekom pandemije COVID–19 putem razgovara telefonom/ mobitelom, informacijskom tehnologijom (uporabom računala: video poziv, socijalne mreže i dr.), razgovora lice u lice te putem mobilnih aplikacija (Viber, Skype, WhatsApp i dr.). Ispitanici koji uopće ne komuniciraju i oni koji vrlo rijetko komuniciraju bilo kojim od ispitivanih načina komunikacije pokazali su veću socijalnu i obiteljsku usamljenost.

RUNJIĆ Babić, Anđela
The socio-cultural context of breastfeeding in the nineteenth and twentieth centuries [Elektronička građa] / Anđela Runjić Babić.
Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - This paper will give a historical account of breastfeeding and explain the socio-cultural context in which the shift from breastfeeding to bottle feeding occurred in the western industrialized nations in the course of the nineteenth and twentieth centuries. Whereas in the nineteenth century most infants were breastfed by the middle of the twentieth century bottle-feeding had become the norm. The growth of artificial infant feeding was related to economic conditions as well as the socio- cultural changes within the burgeoning industrial societies. Aside from the rise of infant formula industry one of the major factors that affected the decline in breastfeeding rates was the shift of breastfeeding from a natural practice into an object of medicine and science. Other cultural factors including religious beliefs, feminism and the changing roles of women within society have affected women's infant feeding choices. Throughout these socio-historical developments breastfeeding was promoted as the best option for infant health. However, concern over breastfeeding rates was also a concern over women's proper mothering behavior and a desire to control women and their mothering practices. - U ovom radu će se kroz povijesni pregled dojenja u zapadnim industrijskim zemljama devetnaestog i dvadesetog stoljeća objasniti društveno-kulturni kontekst unutar kojeg je metoda hranjenja na bočicu zamijenila dojenje. Dok je unutar devetnaestog stoljeća većina djece dojena, do sredine dvadesetog stoljeća hranjenje na bočicu postalo je društvena norma. Širenje metode umjetnog hranjenja bilo je vezano uz ekonomske uvjete ali i društveno-kulturne promjene unutar razvijajućih industrijskih društava. Osim jačanja industrije dojenačke formule jedan od vodećih faktora koji su utjecali na opadanje stopa dojenja bio je transformacija dojenja iz prirodne prakse u predmet medicine i znanosti. Na odluku žena o izboru metode prehrane utjecali su i drugi faktori poput vjerskih uvjerenja, feminizma i promjene ženskih društvenih uloga. U sklopu ovih društvenih promjena dojenje je promovirano kao najbolja opcija prehrane za zdravlje dojenčadi. Međutim, interes za dojenje također je odražavao brigu vezanu uz poželjno majčinsko ponašanje i želju za kontrolom nad ženama i njihovim majčinskim praksama.

Teorijska analiza uloge dijaloga i dionika u upravljanju kriznim situacijama u društvenim medijima [Elektronička građa] / Žanina Žigo. - Graf. prikazi.
Bibliografija: str. 119-121. - Sažetak ; Summary. - Predmet je ovoga rada teorijska analiza odabrane strane i domaće literature čiji rezultati pomažu u razumijevanju kako dijalog i upravljanje dionicima pridonose poslovnim organizacijama u komunikaciji na društvenim medijima tijekom krize. Donedavno postojeće teorije analize dionika postaju nepotpune pojavom društvenih medija. Zbog toga je potrebno istražiti prednosti i nedostatke starih metoda i predložiti nove kako bi se pronašle one najprimjerenije. Cilj je ovog teorijskog rada opisati utjecaje te prednosti dijaloga s dionicima u društvenim medijima tijekom kriznoga događaja. Fokus ovoga rada također je u opisu i važnosti primjene prakse dogovora i rješavanja sukoba s pomoću dijaloga između organizacije i dionika. Ističu se i prednosti novih medija u izgrađivanju i održavanju povjerenja i odnosa s dionicima tijekom kriznoga događaja jer oni mogu utjecati na smanjenje moguće štete za organizaciju i ubrzati njezin oporavak. - This paper scrutinizes theoretically the issue of how dialogue and stakeholder analysis contribute to business organizations and their communication on social media in times of crisis. It provides a theoretical overview of selected foreign and Croatian literature, thus making a contribution to the understanding of their role in crisis management. In view of the emergence and ever more increasing importance of social media, the existing theories of stakeholder analysis have turned out to be incomplete. Therefore, it is necessary to explore the advantages and disadvantages of the older methods and suggest new, more adequate, ones. The aim of this theoretical paper is to describe the impact and the advantages of dialogue with stakeholders on social media during a crisis. It focuses on the importance of applying the practice of agreement and conflict resolution through dialogue between the organization and its stakeholders. The benefits of social media in building and maintaining trust and stakeholder relations during a crisis are also highlighted, as they can help reduce potential harm to an organization and accelerate its recovery.

Why binge-watching? [Elektronička građa] : The prominent motives and analysis of the motivating hedonic and eudaimonic elements of emotional gratification in a binge-watching experience / Vesna Karuza Podgorelec. - Graf. prikazi.
Bibliografija: str. 18-22. - Summary ; Sažetak. - Binge-watching is a popular form of media consumption, and entertainment is one of the main drivers of this activity. This research aims to examine the prominent reasons for binge-watching by re-examining the established television viewing motives, by deepening the analysis of entertainment motives, and by introducing a new possible motive – the need for narrative understanding. Therefore, the researcher combines the factors of the established television viewing motives, the factors of hedonic and eudaimonic emotional gratification in an entertainment experience and introduces the motive of the ease of following storylines. The results of an online survey with 833 participants over the age of eighteen conducted in Croatia suggest that the motives of relaxation, fun (hedonic), habit, easier following of intricate storylines, escape, and thrill (hedonic) are prominent. Eudaimonic motives are less pronounced than hedonic ones, however, these clusters are positively related, which indicates the complexity of enjoyment in binge-watching entertainment. - Binge-watching je popularan oblik medijske konzumacije, a zabava je jedan od izraženih pokretača te aktivnosti. Cilj je istraživanja predočenog u članku istražiti razloge binge-watchinga preispitivanjem etabliranih motiva gledanja televizije, produbljivanjem istraživanja motiva zabave te uvođenjem novoga mogućeg motiva: potrebe za narativnim razumijevanjem. Stoga istraživanje kombinira čimbenike već prije utvrđenih motiva gledanja televizije i čimbenike emocionalnog zadovoljenja hedonističkim i eudamonijskim elementima zabave te uvodi motiv lakšeg praćenja zamršenih linija priče. Rezultati internetskog istraživanja provedenog u Hrvatskoj na 833 sudionika starija od 18 godina pokazuju da su istaknuti motivi binge-watchinga: opuštanje, dobar provod (hedonistički), navika, laganije praćenje zapetljanih linija priče, bijeg i uzbuđenje (hedonistički). Eudamonijski motivi su slabije izraženi od hedonističkih, ali te su skupine motiva u pozitivnoj korelaciji, što upućuje na složenost uživanja u zabavi binge-watchinga.

NIELSEN, Christian Axboe
Decentralizacija organa unutarnjih poslova u SR Hrvatskoj [Elektronička građa] / Christian Axboe Nielsen.
Bibliografske bilješke uz tekst ; bibliografija i izvori: str. 188-191. - Sažetak ; Summary. - Kako su se organi unutarnjih poslova u Socijalističkoj Republici Hrvatskoj i u socijalističkoj Jugoslaviji razvijali, čime su se bavili, do kakvih je promjena došlo i zbog čega? Tijekom otprilike prva dva desetljeća socijalističke Jugoslavije pitanja koja su se odnosila na policiju i državnu sigurnost – ili službenim nazivom na organe unutarnjih poslova – bila su poput većine ostalih pitanja u zemlji vrlo centralizirana. Međutim, postoje indicije da 1966. možda nije bila toliko značajna prekretnica kako se popularno misli te da su neke važne promjene bile ubrzane, a ne pokrenute nakon smjenjivanja Aleksandra Rankovića. Ovaj članak prvenstveno se temelji na izvorima iz 13. maja, službenog časopisa Saveznog sekretarijata za unutrašnje poslove (SSUP). Pažljivo čitanje tog časopisa otkriva članke koji se bave pravnim, konceptualnim, tehničkim i praktičnim pitanjima policije. Časopis je stoga dobro mjesto za prikupljanje informacija radi boljeg razumijevanja organa unutarnjih poslova u Jugoslaviji. Ovaj članak razmatra i analizira početak decentralizacije organa unutarnjih poslova u Hrvatskoj, prije svega u području organa javne sigurnosti. - How did the organs of internal affairs in the Socialist Republic of Croatia and in socialist Yugoslavia develop, what did they actually do, what changes occurred with respect to them, and why? During approximately the first two decades of socialist Yugoslavia, issues related to police and state security – or, as they were officially called, the organs of internal affairs – were, like most other matters in the country, heavily centralized. However, there are indications that 1966 may not have been as significant a watershed moment as is commonly thought, and that some important changes were accelerated rather than triggered after the ouster of Ranković. This article is primarily based on sources from 13. maj, the official journal of the Federal Secretariat for Internal Affairs (SSUP). A careful reading of this journal reveals very detailed articles dealing with legal, conceptual, technical and practical issues affecting policing. The journal is therefore a good place to gather information for a better understanding of policing and internal affairs in Yugoslavia. This article examines and analyses the beginning of decentralization of internal affairs in Croatia, above all with regard to public security bodies.

Delatni potencijal sećanja levice [Elektronička građa] : o samorefleksiji poraza / Todor Kuljić.
Bibliografija: 7 jed. - Sažetak ; Summary. - Kako osmisliti i operativno organizovati sećanja levice u delatnom, a ne u muzejskom pravcu? Šta znači otvoreno se suočiti sa kulturom poraza levice? Razmotrene su dimenzije poraza levice, priroda linearnog i kontingentnog vremena, različita proživljavanja poraza kod fašizma i liberalizma i dijalektika nade i razočarenja. Ukazano je da treba odbaciti jezik psihoanalize (čežnja, nostalgija, žalost, melanholija) i teleološku viziju neoliberalnog pobednika, pa levicu i desnicu shvatiti u novim dimenzijama vremena, unutar novog odnosa Kairosa i Hronosa u digitalnom dobu. Treba se samorefleksivno osvrnuti na greške levice, a naročito na greške iz kojih se može učiti. Treba teorijski probuditi ambiciju. Višeslojnom sećanju levice škodi dominacija jedne vrste sećanja, potrebna je samokontrola i ravnoteža pamćenja nestale socijalne države i vlastitog nasilja. - How could we rethink and organize memories of the Left in an operational and active way? How could one openly confront the Left-Wing culture of defeat? The paper considers some dimensions of the Left-Wing defeat after 1989, the nature of the linear and the contingent time, various defeat experiences of fascism and liberalism and the dialectic of hope and disappointment. One should reject the language of psychoanalysis (longing, nostalgia, sorrow, melancholy) and the teleological vision of the neoliberal winner. The Left Wing and Right Wing should be understood in new dimensions of time within a new relationship between Cairos and Chronos in the digital age. The Left needs self-reflective review of its own mistakes, if it wants to learn lessons for the future. Theory can awake practical ambition. A desirable multilayered Left-Wing memory has been damaged by dominance of one type of memory. The Left needs self-control and a balanced memory of both badly missing socialist welfare state and its own violence.

Dijalektika etnodeterminizma [Elektronička građa] : biopolitičko konstruiranje narativa otpora / Jasmin Hasanović.
Bibliografske bilješke uz tekst ; bibliografija: str. 43-45. - Sažetak ; Summary. - Ovim radom ispituje se da li i na koji način politički poredak u Bosni i Hercegovini determiniran logikom etnopolitike sadrži i producira subverzivni potencijal za vlastitu negaciju. Ideja se postepeno javljala u kontekstu različitih protesta u proteklih pet godina, ali se kao naučno pitanje ozbiljnije oblikovalo tek stapanjem protesta “Pravda za Dženana” i “Pravda za Davida” 2018. godine. Kroz proteste se od jedinstvenog matičnog broja i zdravstva preko radničkih prava i demobilisanih boraca kao politiziranih tijela par excellence pa sve do institucionalizirane instrumentalizacije smrti uočava izražena biopolitička dimenzija sa potpisom etnodeterminizma. Politološkim čitanjem odnosa između kontrahegemonijskih narativa odozdo i njihove sve vidljivije kriminalizacije odozdo, autor problematizira kako ono što se ovdje naziva biopolitikom etnodeterminizma producira narativ otpora kao mogućnost koja osvjetljavanjem naličja samog sistema dovodi u pitanje osnovu njegove legitimacije. - This paper examines whether and to what extent the political order in Bosnia and Herzegovina, determined by the logic of ethnopolitics, contains and produces towards itself a subversive potential for its own negation. The idea gradually emerged in the context of various protests over the past five years, but it has taken a more serious shape as an academic issue by the merging of “Justice for Dženan” and “Justice for David” protests in 2018. Through the protests, starting from the citizens’ ID number and health care to workers’ rights and demobilized war veterans as politicized bodies par excellence up to the institutionalized instrumentalization of death, a biopolitical dimension signed by ethnodeterminism is noticeable. With a political reading of the relationship between counter-hegemonic narratives from below and their increasingly visible criminalization from above, the author problematizes how that which is here called biopolitics of ethnodeterminism produces a narrative of resistance as a possibility which illuminates the reverse of the system, thus calling into question the basis of its legitimation.

Franjo Tuđman i problemi objavljivanja knjige Nacionalno pitanje u suvremenoj Europi [Elektronička građa] / Mirko Ćosić.
Bibliografske bilješke uz tekst ; bibliografija i izvori: str. 787-788. - Sažetak ; Summary. - Na temelju izvora iz fondova Hrvatskoga državnog arhiva, osobito dokumentacije koju je Služba državne sigurnosti Republičkog sekretarijata za unutrašnje poslove Socijalističke Republike Hrvatske prikupila o Bogdanu Radici i Franji Tuđmanu te korespondencije tih dvaju intelektualaca koju je ta služba nadzirala, autor u radu iznosi okolnosti inicijative tiskanja Tuđmanove knjige Nacionalno pitanje u suvremenoj Europi u inozemstvu. Naime, nakon kaznenih progona 1972. i 1981. Tuđman je prisilno udaljen iz društvenoga života, pritiješnjen stvarnošću jugounitarizma. Odvažni napor tiskanja knjige, usprkos svim prijetnjama, prerastao je u pokušaj njegova izlaska iz nametnute izolacije koja je trajala sve do 1988., kada je primljen u Društvo književnika Hrvatske, nakon čega počinje nastupati na javnim tribinama te 1989. objavljuje i knjigu Bespuća povijesne zbiljnosti. - Based on sources from various fonds of the Croatian State Archives, especially the documentation of the State Security Service of the Croatian Republican Secretariat of the Interior regarding Bogdan Radica and Franjo Tuđman and the correspondence between these two intellectuals who were kept under surveillance by the Service, the author presents the circumstances surrounding the initiative to print Tuđman’s book, Nacionalno pitanje u suvremenoj Europi (The National Question in Contemporary Europe), abroad. Namely, after criminal prosecutions in 1972 and 1981, Tuđman was forcibly removed from social life, pressured by the reality of Yugo-unitarism. The bold effort to publish his book despite all threats grew into an attempt to end his imposed isolation, which lasted until 1988, when he was accepted as a member of the Croatian Writers’ Association, after which he began to participate at public forums and, in 1989, published the book Bespuća povijesne zbiljnosti (Horrors of War: Historical Reality and Philosophy).

Geopolitički zaokret liberalnih slovenskih krugova u Primorskoj pred Prvi svjetski rat [Elektronička građa] / Igor Ivašković.
Bibliografske bilješke uz tekst ; bibliografija: str. 215-217. - Sažetak ; Summary. - Autor analizira pisanje primorskih slovenskih liberalnih novina u vrijeme balkanskih ratova 1912. i 1913., prikazuje geopolitičke stavove toga političkoga kruga te ga smješta u širi kontekst sukoba različitih vizija jugoslavenstva. Specifičan položaj primorskih Slovenaca i geopolitičko značenje Trsta odrazili su se na naklonjenost toga dijela Slovenaca što širemu južnoslavenskom konceptu, koji je trebao biti poluga za slovensku političku emancipaciju. Isprva se taj dio Slovenaca zauzima za ujedinjenje južnoslavenskih naroda unutar Habsburške Monarhije, no analizirano razdoblje donosi preokret koji se očituje u ispuštanju habsburškoga okvira u prvom krugu balkanskih ratova. Drugi je pak krug prouzročio isključivanje Bugarske iz južnoslavenskih koncepata, čime se dio primorskih Slovenaca priklanja užoj viziji južnoslavenske državne ideje sa Srbijom u središnjoj ulozi. - The author analyses the writings of Slovene journals from the Primorska (Slovene Littoral) region in the period of the Balkan Wars, in the years 1912 and 1913. The article presents the shift of liberal Slovenes’ attitudes towards the Yugoslav idea and places it in the broader context of the conflict between various geopolitical ideas. The specific position of the Primorska region and Istria as well as the consequential geopolitical importance of Trieste were reflected in the inclination of those liberal Slovenians to the broader concept of the Yugoslav political idea, which included all South Slavic nations and was supposed to be the leverage for Slovenian political emancipation. Initially, the Slovene liberals, who were gathered in the political group named Edinost (Unity) in Trieste and around the journal Soča in Gorizia, favoured the idea of a third political unit within the Habsburg Monarchy, with the ambition of including Trieste and Gorizia into that entity. However, due to fears of being left outside of that third unit, these Slovenes abandoned so called ‘trialist’ idea. The defeats of the Ottoman Empire in the first round of the Balkan Wars resulted in omitting the Habsburg context in Slovene journals from the Primorska region, while the second round caused the exclusion of Bulgaria from the South Slavic state concepts, and pushed those Slovenes towards the narrower version of the Yugoslav idea, where Serbia was to have a central role.

Izvori, geneza i priroda secesionističke retorike u Republici Srpskoj [Elektronička građa] / Aleksandar Savanović, Aleksandar Vranješ, Nevenko Vranješ, Željko Budimir. - Ilustr.
Bibliografske bilješke uz tekst ; bibliografija: str. 118-125. - Sažetak ; Summary. - Bosna i Hercegovina (BiH) je složena državna zajednica sastavljena od dva entiteta i tri konstitutivna naroda. Ta činjenica je posljedica građanskog rata 1992-95. godine, koji je promijenio etničku strukturu BiH. U institucionalnom smislu entitetima je u Dejtonu dat vrlo visok nivo političke samostalnosti. Tzv. “entitetski veto” je nastao u Dejtonu i primjenjuje se u mnogim ključnim tijelima – od Doma naroda, Predstavničkog doma Parlamentarne skupštine BiH, do Predsjedništva BiH. Pored toga, tvrdi se da BiH nema tzv. unutrašnje priznanje i mnogi od aktera na političkoj sceni zagovaraju radikalne ustavne promjene koje bi narušile ili čak potpuno promijenile “Dejtonsku” arhitekturu BiH. Imajući u vidu ove faktore, ne iznenađuje prisutnost secesionističke retorike u političkom prostoru BiH. U ovom radu analiziraćemo secesionističku retoriku u Republici Srpskoj (RS) i pokušaćemo da opišemo moguću secesionističku strategiju u njenim glavnim linijama. Cilj nam je utvrditi da li se može reći da secesionistički argumenti, retorika i eventualno politike predstavljaju integralnu strategiju i koherentnu političku platformu ili su motivisane dnevnopolitičkim razlozima. Takođe ćemo pokušati utvrditi koliko je ova secesionistička retorika institucionalizovana, tj. koliko je zastupljena u zvaničnim dokumentima institucija RS i/ili glavnih političkih stranaka, a koliko ostaje na nivou društvenih pokreta i/ili pojedinačnih političkih subjekata. - Bosnia and Herzegovina (BiH) is a complex state union composed of two entities and three constituent peoples. This fact is a consequence of the 1992-95 civil war, which changed the ethnic structure of BiH. From the institutional perspective, the two entities were given in Dayton a high level of political autonomy. The so-called “entity veto” was created in Dayton, and it is implemented by many key political bodies – from the House of Peoples and the House of Representatives of the Parliamentary Assembly of BiH to the Presidency of Bosnia and Herzegovina. Beside that, it is argued that BiH lacks the “internal recognition” and many of the political actors advocate radical constitutional changes which would disrupt or even completely change the “Dayton” architecture of BiH. Because of that it is not surprising that secessionist rhetoric exists in BiH’s political sphere. The secessionist rhetoric in the Republic of Srpska (RS) will be analysed in this paper and possible secessionist strategy will be described. The aim of this paper is to determine whether secessionist arguments, rhetoric and possibly politics represent an integral strategy and coherent political platform, or whether they are just generated for daily political purposes. Authors will also try to determine whether this secessionist rhetoric is “institutionalised”, i.e. whether it is present in official documents of RS institutions and/or major political parties, or just in the activities of social movements and/or individual political subjects.

Konceptualizovanje siromaštva u socijalnoj politici i praksi socijalističke Jugoslavije [Elektronička građa] / Natalija Perišić, Jelena Vidojević. - Graf. prikazi.
Bibliografske bilješke uz tekst ; bibliografija: str. 169-172. - Sažetak ; Summary. - Fokus ovog rada je na konceptu siromaštva i njegovom prevođenju u propise, politike i prakse zaštite siromašnih tokom perioda u kojem je socijalizam bio zvanična vladajuća doktrina u Jugoslaviji (1945-1991). Uvodni deo propraćen je marksističkim objašnjenjem pojma siromaštva, a zatim ukratko i njegovim adaptiranjem u socijalističkoj Jugoslaviji. Slede opis i analiza kontekstualizovanja siromaštva u periodu socijalizma u Jugoslaviji, kao i njegovih ideoloških i administrativnih konstrukcija i rekonstrukcija kroz sistem socijalne zaštite. Cilj rada je da istraži interpretacije, tj. uokviravanje koncepta siromaštva u politici te njegovu implementaciju u svrhu garantovanja “slobode od nužnosti” u društvu u posleratnoj Jugoslaviji. Metodološki pristup koji je korišćen u radu jeste kvalitativna analiza. - The focus of this paper is on the concept of poverty and its implementation into regulations, policies and practices for the protection of the poor during the period in which socialism was the official doctrine in Yugoslavia (1945- 1991). The introductory part of the paper is followed by the Marxist explanations of poverty and their adaptation in socialist Yugoslavia. The description and analysis of poverty during the socialist period in Yugoslavia, as well as its ideological and administrative constructions and reconstructions in and through the social welfare system are put forward in the central part of the paper. The objective of the paper is to present the way that the concept of poverty was framed in the policy field, how it was interpreted, as well as how these policies were implemented with a view to guaranteeing “freedom from necessity” in the society of post-war Yugoslavia.

Machiavelli [Elektronička građa] : borbe potlačenih i podrivanje "režimā normalnosti" / Davorin Žagar.
Bilješke uz tekst. - Bibliografija: str. 27-29. - Sažetak ; Summary. - Autor u članku ukazuje na suvremenu relevantnost Machiavellijeva nauka sadržanog u Vladaru i Raspravama. U dijalogu s Lefortom i njegovim epohalnim tumačenjem Firentinca (1972) članak nudi alternativno, subverzivno čitanje Machiavellijeve teorije političkog konflikta i pritom, u kritičkom odnosu spram Honnetha (1995), osvjetljuje elemente specifične, makijavelijevske teorije priznanja. Autor tvrdi da je fundamentalno demokratski karakter Machiavellijeva projekta izravno povezan sa sposobnošću plebsa da prepozna svoju novu funkciju u društvenom polju i da na sebe odvažno preuzme queer “identitet”. To je moguće samo uz pomoć i potporu vladara. Plebs u tekstu označava dinamičku koaliciju na različite načine potlačenih skupina. Uz pomoć političke instance pučani trebaju preobraziti svoju težnju da ne budu tlačeni od velikaša u pozitivno usmjerenu težnju da bivstvuju na način koji čuva razliku u odnosu na težnju velikaša za posjedovanjem. Otkrivajući sebstvo kao mjesto nesvodive drugosti, pučani neprestano izumljuju nove načine postojanja u razlici spram “režimā normalnosti” i na taj način postaju nepresušni izvor društvene inovacije koja stoji na dispoziciji čitavom društvu. Poqueeravanje plebsa omogućuje viši stupanj zajedničkog bivstvovanja. Snaga demokratskog društva izravno ovisi o vitalitetu težnje pučana i njihovoj sposobnosti da neprestano osmišljavaju i proizvode nove načine života. - In this paper the author highlights the contemporary relevance of Machiavelli’s teaching as contained in The Prince and Discourses. In a dialogue with Claude Lefort and his groundbreaking interpretation of the Florentine (1972),this paper offers an alternative, subversive reading of Machiavelli’s theory of political conflict. At the same time, the author highlights the elements of a specific Machiavellian theory of recognition through a critical engagement with Honneth (1995). The author argues that the fundamentally democratic character of Machiavelli’s project is directly related to the ability of the plebs to recognize their novel function in the social field and to audaciously adopt queer “identity”. This is made possible only with the help and the support of the prince. In the text, the plebs represent a dynamic collation of diverse groups (of Others) which are being oppressed in the society. The plebs are invited to transform their desire not to be oppressed into a positive desire “to be” and become in such a way that enables them to maintain their difference in contrast to the greats. By discovering the “self” as a place of radical alterity, the plebs ceaselessly invent new modes of being which are opposed to the “regimes of the normal”. In this way the plebs become an inexhaustible source of innovations which are available for the entire citizenry. Queering of the plebs enables a higher degree of (our) common being in the society. The strength of a democratic society directly depends on the vitality of the plebs’ desire and their ability to imagine, produce and sustain new modes of life.

Moral foundations theory in the context of a political scandal [Elektronička građa] : two cross sectional studies in Croatia / Darko Hren, Ivan Buljan, Ana Marušić. - Graf. prikazi.
Bibliografija: 16 jed. - Summary. - The aim of this study was to examine the moral foundations structure in the Croatian population, and to examine possible changes in moral foundation structure after a major political scandal in Croatia. Methods: We conducted an online survey using Moral Foundations Questionnaire and Key Social Issues Scale, which was distributed in two waves, in 2009 and 2014. Participants were invited from the Faculties of Humanities and Social Sciences at the universities in Zagreb and Split and asked to distribute the survey to colleagues and friends. Results: 3000 participants completed the survey in 2009, 1323 participants completed the survey in 2014. In both samples, most participants reported that they relied more on individual foundations of “Care/Harm” and “Fairness/Cheating”, than on relational foundations of “Loyalty/Betrayal”, “Authority/Subversion” or “Sanctity/Degradation”, which are typically more valued by traditionally oriented or conservative individuals. Comparison of the two measurement time points indicated that scores on traditional foundations significantly decreased, while liberal values increased. These changes were triangulated and confirmed by the results on the Key Social Issues Scale. Conclusion: In order to encourage students and training doctors to more readily engage in research, exposure to re-search and research participation could have an incremental value to existing research education in medical schools.

Novi oblici političke participacije [Elektronička građa] : analiza dinamike političke kampanje na forumu 4chan / Matej Mikašinović-Komšo. - Ilustr., graf. prikazi.
Bibliografske bilješke uz tekst ; bibliografija: str. 86-89. - Sažetak ; Summary. - U radu se analizira i kritički razmatra politička kampanja korisnika internetskog foruma 4chan – specifičnije, s podforuma /pol/ (Politically Incorrect), u svrhu utvrđivanja predstavlja li ona novi oblik političke participacije. Kroz prikaz relevantne literature o političkoj participaciji te kroz prikaz povijesti, organizacije i koncepcije foruma 4chan, uspostavljaju se temelji na kojima se razrađuje kvalitativna analiza studije slučaja političke kampanje korisnika /pol/-a. Glavni nalazi analize odabrane političke kampanje pokazuju da je ona kolektivna, subverzivna, da koristi troll strategije radi realiziranja konzervativnih ciljeva te da sudjelovanje korisnika u njoj, zbog političke motiviranosti djelovanja, predstavlja oblik političke participacije. takva politička participacija se također, zbog naglaska na djelovanju manjeg broja pojedinaca iz cijelog svijeta, nedostatka organizacijske hijerarhije te drugačije logike upotrebe društvenih mreža za dijeljenje materijala, može smatrati novim oblikom političke participacije. - The focus of this work is the analysis and critical consideration of the political campaign from the forum 4chan’s – more specifically, from the subforum / pol/ (Politically Incorrect), in order to determine whether it represents a new form of political participation. By detailing major points of relevant literature on political participation, as well as through detailing the history, organization and conception of the forum 4chan, the author prepares a ground for the case study of a political campaign from /pol/. the main findings of the analysis of the selected political campaign show that it is collective, subversive, that it uses troll strategies in order to successfully realize conservative political goals and that the participation of the site’s users in them can be considered to represent a form of political participation, due to the politically motivated nature of such participation. Such a form of political participation can also be considered to be an inovative, new form of political participation, through its emphasis on the participation of a smaller number of people throughout the world, lack of an established organizational hierarchy, and its different use of social media for content sharing.

Politička ekonomija i kritika teorije društvenog ugovora u Hegelovoj Filozofiji prava [Elektronička građa] / Domagoj Vujeva.
Bilješke uz tekst. - Bibliografija: str. 123-126. - Sažetak ; Summary. - Autor tematizira recepciju političke ekonomije u Hegelovoj Filozofiji prava. Ta je recepcija bila presudna za razvoj Hegelove pravno-političke filozofije i njenu zrelu formulaciju, ali je istovremeno njome posredovan i Hegelov odnos prema modernom prirodnom pravu i ugovornoj političkoj teoriji. Oslanjajući se na Strpićeve nalaze, autor pokazuje kako je mjestom realizacije ugovornog modela države Hegel smatrao građansko društvo. Zakonitosti imanentne modernoj tržišnoj ekonomiji, koje je “otkrila” politička ekonomija, prema Hegelovu sudu čine izlišnim ugovornu konstituciju države, ali i predstavljaju unutarnju mjeru kritike ugovorne teorije. To međutim ne znači da Hegel prihvaća model društva klasične političke ekonomije niti njeno razumijevanje odnosa države i društva. On dovodi u pitanje prije svega njenu središnju pretpostavku o sposobnosti tržišta za samoregulaciju, zbog čega smatra nužnom državnu regulaciju tržišta. U posljednjoj analizi pokazuje se kako je “općenitost” građanskog društva utemeljena u “općenitosti” političke države, koja predstavlja viši stupanj ozbiljenja čovjekove slobode. - The author deals with Hegel’s reception of political economy in the Philosophy of Right, showing that reception to be decisive for the development of Hegel’s legal and political philosophy and its mature form, but also for his understanding of the modern natural law tradition and the theory of social contract. Relying on the findings of Dag Strpić, the author argues that Hegel considered “civil society” to be the place of realization of the contractual idea of the state. The “laws” immanent to modern market economy, which were “discovered” by political economy, make in Hegel’s view contractual constitution of the state superfluous and provide at the same time the internal measure for the critique of the contractual theory. This, however, does not mean that Hegel accepts the social model of classical political economy, nor its understanding of the relation between the state and society. He questions its central assumption on the self-regulatory capacity of the market, for which reason he finds necessary the regulation of the market by the state. In the final analysis, as it is shown, the “universality” of civil society is grounded in the “universality” of the political state, which is a higher level of actualization of human freedom than civil society.

RIBAREVIĆ, Luka
Politička ekonomija u Levijatanu [Elektronička građa] : Hobbes, Macpherson i Strpić / Luka Ribarević.
Bibliografska bilješka uz tekst ; bibliografija: str. 144-147. - Sažetak ; Summary. - U magistralnoj studiji razvoja klasične političke ekonomije Robna proizvodnja i udruženi rad u Marxovoj kritici političke ekonomije Daga Strpića veoma važno mjesto zauzima Thomas Hobbes. Prema Strpiću Hobbes uspostavlja novi metodološki i kategorijalni okvir za razumijevanje političke zajednice u moderni. Za razliku od velike većine interpretacija Hobbesove philosophiae civilis Strpić Hobbesa ne čita samo kao utemeljitelja moderne političke teorije, nego i klasične političke ekonomije. U tekstu se političko-ekonomski aspekt Hobbesove znanosti o politici razmatra posredstvom kritičke analize dijaloga koji Strpić vodi s utjecajnim tumačenjem C. B. Macphersona. Strpić usvaja bitne elemente Macphersonove interpretacije fokusirane na e konomske pretpostavke Hobbesova političkog mišljenja, ali istovremeno odstupa od njegova razumijevanja Levijatana. Na toj se pozadini nastoji utvrditi spoznajne domete i ograničenja političko-ekonomskog čitanja Hobbesa koje dijele Strpić i Macpherson. - Thomas Hobbes plays a major role in Commodity Production and Associated Labour in Marx’s Critique of Political Economy, a seminal study of the development of political economy written by Dag Strpić. According to Strpić, Hobbes established a new methodological and categorial framework for the understanding of the political community in modernity. Departing in that respect from the vast majority of interpretations of Hobbes’ philosophia civilis, Strpić reads Hobbes not only as the founder of modern political theory, but of classical political economy as well. In the article the political-economic aspect of Hobbes’ science of politics is examined through a critical analysis of the dialogue Strpić engages in with the influential interpretation of C. B. Macpherson. Although Strpić adopts important elements of said interpretation, he at the same time deviates from Macpherson’s understanding of Leviathan. On such a backdrop the author proposes to determine the scope and limitations of political-economic reading of Hobbes, characteristic of both Strpić and Macpherson.

KOVAČ, Bogomir
Političkoekonomske marginalije o recepciji Marxa u XXI. stoljeću [Elektronička građa] : (u povodu čitanja knjige Daga Strpića Robna proizvodnja i udruženi rad u Marxovoj kritici političke ekonomije) / Bogomir Kovač.
Bibliografija: str. 28-29. - Sažetak ; Summary. - Političkoekonomskom analizom recepcije Marxa u Strpićevoj knjizi o Marxovoj kritici političke ekonomije autor želi pokazati kakav je suvremeni položaj i koja je moguća aktualnost Marxove analize. Do aktualizacije i povratka Marxu uvijek dolazi u vrijeme kriza, njegova intelektualna sudbina ovisi o preobrazbi sadašnjeg kapitalizma i njegovoj alternativi. Paradoks teorijske nedovršenosti u Marxovoj analizi zbog njegove spoznajne težnje za savršenstvom epistemologije kapitalizma postaje sudbina svih marksističkih interpretacija, pa tako i Strpićeve. Problem Marxa danas je upravo u metafizici teorije vrijednosti i cijeloga robnog sustava koji ne omogućuje ontologijske preobrazbe vrijednosti, kapitala i kapitalizma. Njegov teorijski pristup je više fiziokratski nego novčani, više ekonomski nego politički. Zato Bidetova rekonstrukcija Marxa u okvirima moderne polazi od “metastrukture” općega političkopravnog momenta, koji u marksovskoj kritici nedostaje. Primjeren pristup podrazumijeva poimanje kapitalizma kao eminentno političkoga: politički kapitalizam, kako pokazuje autor, nije poseban oblik kapitalizma, nije historijski vezan uz suvremeni oblik kapitalizma XXI. stoljeća (Kina...), nego je njegova univerzalna povijesna forma. Marxova je kritika političke ekonomije moderna upravo na tom nedovoljno određenom putu njegove analize. Politički kapitalizam kao “kapitalizam općenito” pokazuje svoju relevantnost u analizi suvremenih kriza, koje nisu više samo ekonomske nego ekologijske, pa i pandemijske. U nizu recentnih kriza političkog kapitalizma pokazuje se kako smo suočeni s izborom između realnog autokratskog "barbarskog kapitalizma" i više utopijskog "kozmopolitskog ekosocijalizma". - In Strpić’s book on Marx’s critique of political economy, the analysis of political and economic reception of Marx serves as starting point for the author’s assignment of contemporary position and relevance of Marx’s analysis. Both actualization and return to Marx always occur in the times of crisis, therefore his intellectual fate depends on changes within contemporary capitalism and its alternatives. In Marx’s analysis, the paradox of theoretical incompleteness stems from his aim for ideal epistemology of capitalism, which is also present in later Marxist interpretations, even Strpić’s. The contemporary problem of Marx lies in the metaphysics of theory of value and in the whole structure of commodity production, which prevents ontological transition of value, capital and capitalism. His approach is physiocratic more than it is pecuniary, and more economic than it is political. This is why Jacques Bidet’s reconstruction of Marx in the terms of modernity is based on “metastructure”, which is a universal politically legal point that is not present within Marx’s critique of political economy. Such a different approach presupposes understanding capitalism as inherently a political project. As it is proven by the author, political capitalism is not a special form of capitalism, nor it is historically connected with contemporary capitalism of the 21st century (in China and elsewhere), but is moreover its universal historical form. Marx’s critique of political economy turns out to be contemporary precisely at this overlooked point of his analysis. Political capitalism as “capitalism in general” demonstrates its relevance in the analysis of contemporary crises, which are not just politicaleconomic, but also ecological and even pandemic. In a series of crises of political capitalism we are faced with a choice between real autocratic "barbaric capitalism" and more utopic "cosmopolitan" eco-socialism.

Razvoj makroekonomije i rezolutivno-kompozitivna metoda [Elektronička građa] / Josip Lučev. - Graf. prikazi.
Bilješke uz tekst. - Bibliografske bilješke uz tekst ; bibliografija: str. 50-54. - Sažetak ; Summary. - Cilj je ovog teksta pokazati svrhovitost upotrebe hobsovske rezolutivno-kompozitivne metode kao uporišta za analizu povijesti moderne ekonomske misli,a naročito makroekonomije. Najprije se obrazlaže važnost rezolutivno-kompozitivne metode u djelu Daga Strpića. Zatim se pokazuju osnovna obilježja stiliziranih pomaka u paradigmama ekonomske misli (neoklasična ekonomija – kejnzijanska ekonomija – slobodnotržišna paradigma) koji u svjetlu ove reinterpretacije dobivaju strukturu rezolucije-kompozicije-rerezolucije. Nudi se i interpretacija povijesti ekonomske znanosti “nakon Hayeka” kao perioda dominacije kompozitivnog elementa, odnosno kejnzijanskih makroekonomskih koncepata koji se oslanjaju na agregate. Objašnjavaju se neoklasična sinteza i osnovne metodološke dvojbe koje je dugotrajna integracija Keynesa u mainstream pretpostavljala (uključujući izbor između agregata i agregiranih pojedinaca u osnovi konceptualizacije makroekonomije). Problematizacijom tih dvojbi prate se komplementarni odnosi dugog roka, pretpostavljene racionalnosti aktera i optimalnih slobodnotržišnih rezultata. Prikazuje se i stanje znanosti na kraju 20. i početku 21. stoljeća, odnosno Lucasovo metodološko zaoštravanje Friedmanovih ideja, kao i dovršeni oblik tog idejnog sklopa u okviru “teorije realnih poslovnih ciklusa”. Ponovna dominacija rezolutivnog elementa (slobodnotržišna paradigma) koji konstituira ideju samoregulativnog tržišta oko savršeno racionalnog pojedinca dovodi nas u stvarne poteškoće: redukcija na savršeno racionalnog pojedinca (rezolutivni manevar) ne bi smjela konstituirati veću cjelinu kompozitivno ukoliko je ta redukcija nerealistična na način koji dramatično ograničava samu korisnost teorije. Stoga se zaključno otvara i pitanje primjene ovih ideja na predviđanje kriza i formuliranje odgovora na njih. - The objective of this text is to demonstrate the plausibility of the use of the Hobbesian resolutiv e compositive method as a base for analysis of the history of modern economic thought, and particularly of macroeconomics. Firstly, the importance of the resolutive-compositive method for the works of Dag Strpić is explained. Secondly, the text shows the basic tenets of stylized shifts in economic paradigms (neoclassical economics – Keynesian economics – free-market paradigm) which are reinterpreted here as resolution-composition- reresolution. An interpretation of the intellectual history “after Hayek” is also offered, focusing on Keynesian macroeconomics based on aggregates. The text then explains neoclassical synthesis and the elementary methodological dilemmas it represented through its long integration of Keynes into the mainstream (including the choice of aggregates or aggregated individuals as the basis of macroeconomics). The text follows the complementary relationship of the effects of long-run analysis, the assumption of rationality and optimal free-market results. The state of the economic mainstream at the end of Lučev, J., Razvoj makroekonomije i rezolutivno-kompozitivna metoda 55 the 20th century and the beginning of the 21st century is then shown – particularly the Lucasian methodological upgrade of Friedman’s ideas and the developed form of this conceptual framework within the Real Business Cycles theory. The renewed dominance of the resolutive element (free-market paradigm) – constituting the idea of a self-regulating market around the perfectly rational individual – leads us into a challenging situation. The reduction to a perfectly rational individual (resolutive maneuver) should not constitute a larger (compositive) whole if such a reduction is unrealistic to an extent that dramatically limits the very usefulness of the theory.

ČUSTOVIĆ, Ajla
Smrtna kazna za otpadništvo u islamu [Elektronička građa] / Ajla Čustović.
Bilješke uz tekst. - Bibliografija: str. 147-149. - Sažetak ; Summary. - U članku se sagledava jedna od točaka napetosti u problematici odnosa islama i liberalnog razumijevanja ljudskih prava – sloboda religije naspram smrtne kazne za otpadništvo u islamu. Autorica kritički pristupa ekstremističkom tumačenju islama u kojem se smrtna kazna za otpadništvo prakticira kao jedna od odlika Medinskog ideala – te, preuzimajući Tibijev pojam, odbacuje ekstremističke pokušaje oživljavanja vremena proroka Muhameda kao “izmišljanje tradicije”. Oslanjajući se na progresivnu islamsku misao, autorica toj problematici prilazi iz dvaju smjerova: prvi je smjer preispitivanje izvora smrtne kazne za otpadništvo u Kur’anu i tradiciji proroka Muhameda, a drugi odbacivanje smrtne kazne za otpadništvo kao prakse proturječne ideji ljudskih prava. - In this article, the author approaches one of the tension points within the problematics of Islam and liberal understanding of human rights – freedom of religion in opposition to the death penalty for apostasy in Islam. The author critically approaches the extreme interpretation of Islam – within which the death penalty for apostasy is practiced as one of the characteristics of Medina ideal – and, by adopting Tibi’s term, dismisses their attempts of revival of Prophet Muhammad’s time as “the invention of tradition”. Relying on progressive Islamic thought, the author approaches this problematics from two directions: first, through examination of the death penalty sources in Islam: Qur’an and the tradition of Prophet Muhammad, and second, through dismissal of the death penalty for apostasy as a practice which is contradictory to the idea of human rights.

LALOVIĆ, Dragutin
Strmim stazama politologa Daga Strpića u čitanju Marxa [Elektronička građa] / Dragutin Lalović.
Bibliografske bilješke uz tekst ; bibliografija: str. 99-105. - Sažetak ; Summary. - U tekstu se prikazuju i vrednuju glavne odlike znanstvenog pristupa, načina argumentacije i mogućih analitičko-istraživačkih i razvojno-općedruštvenih dosega Strpićeve teorijske ostavštine kada je riječ o njegovu fundamentalnom istraživanju Marxove epohalne kritike političke ekonomije, ponajprije u knjizi Robna proizvodnja i udruženi rad u Marxovoj kritici političke ekonomije (2017/1991). Najprije se predstavlja inicijalni Strpićev istraživački program suvremenoga marksovskog dovršavanja i razvijanja Marxove “Kritike” (1982). U središtu izlaganja sažeto su prikazani glavni elementi Strpićeva čitanja Marxove kritike političke ekonomije. Prvo, ocjena Marxove recepcije klasične britanske političke teorije i političke ekonomije, kao i recepcije te baštine u Hegelovoj filozofiji. Drugo, rekonstrukcija logike Marxova kategorijalnog aparata kao apstraktne sfere “kapitala općenito”, u razlici spram konkretne sfere konkurencije “mnogih kapitala”, a unutar tog polja primjereno određenje “robe općenito” kao logičkog polazišta cjelokupnoga teorijskog sustava i vrijednosti kao zakona kretanja tržišnih cijena. Treće, primjereno je Kapitalu pristupiti iz dinamičke perspektive teorije socijetalnih ciklusa i cikličkoga razvoja; iz tendencijskih zakona povijesnog razvoja kapitalističke akumulacije valja razumjeti strukturu kapitala kao društvenog procesa proizvodnje, prometa i reprodukcije. Četvrto, razlikovanje marksovskoga (znanstvenog i kritičkog) od marksističkoga (ideologijskog i klasno zasnovanog) pristupa kritici političke ekonomije. Zatim se pomno prikazuje i kritički vrednuje Strpićevo intrigantno shvaćanje dvojstva klasičnih političkih teorija, koje se, po njegovu sudu, očituje kao razlikovanje između Machiavellijeve “politikologije”, koja politiku shvaća u kategorijama vlasti i vladanja, i Hobbesove “politologije”, kao sistematske znanosti o građanskoj zajednici. - The text delineates and evaluates the principal features of the scientific approach, mode of argumentation and the possible scope of Strpić’s theoretical legacy in terms of research and analysis as well as the development of society in general. In particular, the focus is on his fundamental research of Marx’s epochal critique of political economy, presented primarily in the book Commodity Production and Associated Labour in Marx’s Critique of Political Economy (2017/1991). First of all, an account is given of Strpić’s initial programme of research into contemporary Marxian completing and developing of Marx’s “Critique” (1981/1982). The central point of the exposé is a concise overview of the main elements of Strpić’s reading of Marx’s critique of political economy. The first element is an evaluation of Marx’s reception Politička misao, god. 57, br. 2, 2020, str. 72-106 106 of classical British political theory and political economy, and of the reception of this legacy in Hegel’s philosophy. The second is a reconstruction of the logic of Marx’s apparatus of categories as the abstract sphere of “capital in general”, in distinction to the concrete sphere of competition between “many capitals”, and, within that field of research, an adequate definition of “commodity in general” as a logical starting point of the entire theoretical system and of value as law of fluctuation of market prices. Thirdly, it is apt to approach The Capital from the dynamic perspective of the theory of societal cycles and cyclical development; the tendency laws of historical development of capitalist accumulation must lead to the understanding of the structure of capital as a social process of production, circulation and reproduction. The fourth element is differentiation between the Marxian (scientific and critical) and the Marxist (ideological and class-based) approaches to the critique of political economy.

PETAK, Zdravko
Suvremena znanstvena relevantnost Marxove analize kapitala [Elektronička građa] : (u povodu rasprave o knjizi Daga Strpića Robna proizvodnja i udruženi rad u Marxovoj kritici političke ekonomije) / Zdravko Petak.
Bibliografske bilješke uz tekst ; bibliografija: str. 68-70. - Sažetak ; Summary. - U radu se razmatraju relevantnost Marxove analize kapitala i značaj prikaza te analize u Strpićevoj knjizi o Marxovoj kritici političke ekonomije. Autor na početku rada naznačuje neke elemente općeg teorijskog okvira u koji je Strpić postavio svoje istraživanje Marxove kritike političke ekonomije. Nakon toga razmatraju se dva temeljna pitanja koja se tiču same Marxove kritike političke ekonomije: 1. Može li se iz Marxova teorijskog sklopa izvući temeljna potka za razumijevanje važnosti institucija u ekonomskom procesu na način na koji ih vide predstavnici starog i novog institucionalizma u političkoj ekonomiji? 2. Može li se iz čitanja Marxova kategorijalnog aparata izvesti jedinstveno razumijevanje ekonomskih kriza? U odgovoru na prvo pitanje pokazuje se da postoje određene sličnosti između Marxova i pristupa ekonomskih institucionalista, no isto tako i značajne razlike između tih dvaju pristupa. U odgovoru na drugo pitanje pokazuje se da Marx nije razvio jedinstvenu teoriju kriza, već da se u njegovu djelu mogu pronaći argumenti za dvije ili tri različite teorije kriza. Nakon toga se u najopćenitijim crtama pokazuje da je Marxova kritika političke ekonomije prvenstveno situirana svojim odnosom prema klasičnoj školi, ali da posjeduje i određeni potencijal korespondiranja sa suvremenom ekonomskom znanošću. Autor pokazuje da se pravac te korespondencije odnosi prvenstveno na objašnjenje temeljnih tendencija u razvoju kapitalističkog sistema. U zaključku rada navode se neki od temeljnih Strpićevih doprinosa političkoj ekonomiji. - The paper discusses the relevance of Marx’s analysis of capital and the manner in which that contribution is presented in the book on Marx’s critique of political economy written by Dag Strpić. At the beginning of the paper, the author indicates some elements of the general theoretical framework within which Strpić formulated his research on Marx’s critique of political economy. The paper raises two fundamental questions concerning Marx’s critique of political economy: 1. Can a fundamental starting point be drawn from Marx’s theoretical framework for understanding the importance of institutions in the economic process, as seen by the representatives of old and new institutionalism in political economy? 2. Can a unique explanation of economic crises be derived from reading Marx’s categorical apparatus? The answer to the first question shows that there are certain similarities between Marx’s approach and the approach advocated by economic institutionalists, but also there exist significant differences between the two approaches. The answer to the second question shows that Marx did not develop a unique theory of crises, since there are arguments indicating the existence of two or three different crisis theories which can be found in his work. After that, the author shows, using most general terms, that Marx’s critique of political economy is primarily situated by his attitude towards the classical school, but that it also has some potential to correspond with modern economics. The author shows that the direction of correspondence refers primarily to the explanation of fundamental tendencies in the development of the capitalist system. The conclusion of the paper reviews some of Strpić’s fundamental contributions to political economy.

Verita effettuale della cosa politica u Makijavelijevoj Mandragoli [Elektronička građa] / Bojan Kovačević, Marko Simendić.
Bibliografske bilješke uz tekst ; bibliografija: str. 57-59. - Sažetak ; Summary. - Makijaveli putokaz za uspostavljanje poretka među ljudima koji svoj sebični lični interes pretpostavljaju opštem dobru šalje u dramskoj formi komedije, u Mandragoli. Prvo predstavljamo likove u komadu kao junake doba radikalnog odsustva smisla. Potom u Liguriovom planu za osvajanje udate lepotice Lukrecije pronalazimo smernice za mirno uspostavljanje novog poretka u senci starog koji, onemoćao, prevaren i slab, ne pruža nikakav otpor. U trećem delu u ovoj naizgled lakoj komediji rasvetljavamo uputstvo za skrivenu revoluciju, koja se ostvaruje zahvaljujući smelosti državnika i lukavosti njegovog savetnika. Zaključujemo da Makijaveli u Mandragoli razmatra scenario koji nije dobio dovoljno pažnje u njegovim drugim delima: uspostavljanje dobrog poretka u iskvarenoj republici. - In The Mandrake, Machiavelli uses the form of a comedic play to point at a way of establishing a constitution suitable for people who put their personal interest before the common good. In this paper we first present the play’s characters as champions of an age that is radically deprived of sense and purpose. In Ligurio’s plan to win over the beautiful but married Lucretia, we recover the guidelines for the peaceful creation of a new constitution within the shadows of the old political system which, debilitated and weak, offers no resistance. Finally, in this seemingly frivolous play, we uncover a pathway to a hidden revolution, accomplished by the statesman’s bravado and his advisor’s cunning. We conclude that in The Mandrake Machiavelli sketches up the scenario which never got sufficient attention in his other works: how to establish a good constitution within a corrupt republic.

PERKOVIĆ Paloš, Andrijana
Croatian leadership and Jews in the 1990s [Elektronička građa] / Andrijana Perković Paloš. - Graf. prikazi.
Bibliografija: str. 27-34. - Summary. - What was the attitude of the first Croatian president Franjo Tuđman and the Croatian leadership towards the Holocaust and the Jewish community in Croatia in the 1990s? Some considered Tuđman a Holocaust denier because of the purportedly controversial parts of his 1989 book Bespuća povijesne zbiljnosti (Wastelands of Historical Reality). The Croatian leadership was accused of minimizing World War II crimes of the Ustasha regime and rehabilitating the World War II Independent State of Croatia. Methods: We analyzed archival documents, Tuđman’s published correspondence, controversial parts of his Wastelands of Historical Reality, his public statements, biographical writings of contemporary Croatian leaders, and newspaper articles. We scrutinized the Serbian propaganda against Croatia in the 1990s, the position and role of the Jewish community and prominent Jews in Croatian public life as well as the relations between Croatia and Israel. Findings: The Croatian leadership and the Jewish community maintained good relations in the 1990s. Some prominent Croatian Jews actively advocated for Croatia’s international recognition and refuted certain authors’ and some Jewish international circles’ accusations of antisemitism among Croatian leadership. Jews participated at the highest levels of Croatian government. Democratic changes at the beginning of the 1990s enabled national, religious, political and other freedoms for minorities in Croatia, including the Jewish community. Still, some authors considered Tuđman an anti-Semite and a Holocaust denier. These opinions were partly shaped by quotes from the Wastelands of Historical Reality taken out of context and published by Serbian propagandists. This propaganda successfully shaped the false perception of official antisemitism in Croatia and has contributed to the delay in the establishment of the diplomatic relations between Croatia and Israel for more than five years after Israel had recognized Croatia.

KARDUM, Tomislav
Ideološki pogledi Milana Šufflaya [Elektronička građa] / Tomislav Kardum.
Bibliografske bilješke uz tekst ; bibliografija: str. 928-931. - Sažetak ; Summary. - Rad nastoji uklopiti ideološke poglede Milana Šufflaya u širi europski kontekst antimodernističkih i antiprosvjetiteljskih tendencija. S time je povezan i Šufflayev pogled na hrvatsku naciju i hrvatski nacionalni identitet. U radu se razmatraju i Šufflayeva geopolitička promišljanja. Šufflay je kritičar modernoga svijeta i njegovih manifestacija, zastupnik je organskoga nacionalizma, a hrvatski nacionalni identitet konstruira nasuprot jugoslavenskom, ističući važnost povijesnoga pamćenja, kulture, geografije i rase pri oblikovanju nacije, a marginalizirajući značenje jezika. Isticat će katoličku vjersku pripadnost Hrvata i pripadnost zapadnoj civilizaciji kao temeljne značajke hrvatskoga nacionalnog identiteta. - The paper attempts to explain Milan Šufflay’s ideological views in a broader European context of anti-modernism and counter-Enlightenment tendencies. Milan Šufflay was a critic of the modern world and its manifestations. His views were similar to other counter-Enlightenment thinkers such as Oswald Spengler, Henri Bergson, Gustave Le Bon, etc. Šufflay despised individualism and rationalism, and admired collectivism and power of the myth. Šufflay thought that the answer to problems of the modern world lay in a return to medieval values – i.e. spiritual values against material values, which were predominant in his time. Šufflay’s anti-modernist views were closely connected with his nationalism. He was a proponent of organic nationalism and claimed that a nation is a community of the present, former, and future generations. In his works, he stressed the importance of historical memory, culture, geography, and race as factors in the shaping of the nation. He emphasised the Catholic faith of Croats and Occidentalism, which he claimed manifested through the whole of the nation’s history and should therefore be represented in the collective memory of Croats. In that sense, Šufflay’s views were similar to those of Croatian interwar nationalists (e.g. Filip Lukas), and he also constructed Croat national identity vis-a-vis Yugoslavism. Because of the great differences between Croats and Serbs, Šufflay claimed that Yugoslavia was an artificial and unsustainable state. Šufflay’s geopolitical insights were also connected with his essentialist vision of the two perennial antagonistic camps – East and West. In that sense, he anticipated Samuel Huntington’s idea about the Clash of Civilizations.

Romi u Hrvatskom primorju za vrijeme Drugoga svjetskog rata [Elektronička građa] / Danijel Vojak, Ivan Brlić. - Graf. prikazi.
Bibliografske bilješke uz tekst ; bibliografija: str. 863-867. - Sažetak ; Summary. - Povijest romskoga stanovništva često je obilježena nasiljem, stradanjem i progonima, posebice od njihova doseljavanja na europska područja nakon XII. stoljeća, a to traje, s manjim intenzitetom, sve do danas. Kontekst takva položaja Roma u europskim državama jest u njihovu negativnom percipiranju kao besposličara i lijenčina, kriminalaca, otimača djece, špijuna i sl. Upravo su to razlozi nacističkoga pokušaja genocida nad njima za vrijeme Drugoga svjetskog rata. Sličan odnos prema Romima imale su talijanske fašističke vlasti, a on se temeljio na rasnim zakonima. Talijanske vlasti imale su tijekom Drugoga svjetskog rata nadležnost i nad Hrvatskim primorjem te znatnim dijelom hrvatske istočnojadranske obale. Istraživanje u radu usmjereno je na analizu položaja romskoga stanovništva u Hrvatskom primorju, pri čemu će se posebice analizirati odnos ustaških i talijanskih vlasti prema Romima. U radu će se koristiti dosad neobjavljena građa iz Državnoga arhiva u Rijeci te građa iz Hrvatskoga državnog arhiva, kao i relevantna literatura. - During World War II, the Roma population in Croatia was exposed to the repression and assimilation policy of several authorities. Ustasha authorities in the Independent State of Croatia persecuted Roma based on racial laws aimed at their genocidal extermination. This paper analyses the position of Roma in some present-day Croatian areas, especially in the Croatian Littoral, which were under Italian (Fascist) rule during the war. Only a few dozen Roma lived in these border areas before the war, who were already subject to the repressive-assimilation policies of the official Italian authorities. This is evidenced by the provisions issued by the aforementioned authorities with the aim of better monitoring the movement of Roma in the Italian–Yugoslav border area. As World War II approached, it was noticeable that the Italian authorities’ relationship with the Roma was intensifying, because they feared, first and foremost, Roma espionage and association with the anti-fascist (communist) resistance movement. The deportation of Roma from the wider Istrian area to internment camps in southern Italy, Sardinia, etc. must be observed in this context. According to other Roma living in the Croatian Littoral, the Italian authorities often sought to control their movements, especially after the establishment of the Independent State of Croatia in April 1941, when attempts were made to reach the Roma in areas under Italian rule. This paper studies the attitude of Croatian anti-fascists towards the Roma. Some tension (conflicts) can be seen in the perception of the indigenous population towards the Roma, in this case in the Omišalj area on the island of Krk. The Roma population managed to survive the war in the Croatian Littoral area, though a considerable number of them died.

Zaštita nacionalnih manjina na lokalnoj razini u Hrvatskoj i Bosni i Hercegovini [Elektronička građa] / Dana Dobrić Jambrović, Nevenko Vranješ.
Bibliografske bilješke uz tekst ; bibliografija i izvori: 38 jed. - Sažetak ; Summary. - S obzirom na to da pojedinci u najvećoj mjeri svoje potrebe i interese ostvaruju na razini koja im je teritorijalno najbliža, lokalna bi vlast trebala biti ključno uporište za realizaciju manjinske politike. Glavno istraživačko pitanje rada odnosi se na ulogu lokalnih jedinica u implementaciji načela jednakosti i osiguranju zaštite nacionalnih manjina od diskriminacije. Kao teorijski okvir istraživanja odabrana je tripartitna tipologija obveza država u zaštiti općih ljudskih prava na temelju koje su ponuđeni prijedlozi za jačanje uloge lokalnih jedinica u ostvarivanju prava manjina. Zatim je primijenjena komparativna metoda istraživanja radi usporedbe regulacije položaja manjina u Hrvatskoj i Bosni i Hercegovini. Cilj je utvrditi koji su standardi manjinske politike primijenjeni na lokalnoj razini promatranih zemalja te u kojoj mjeri oni odgovaraju predloženim instrumentima jačanja uloge lokalnih jedinica. Svrha je rada na temelju rezultata istraživanja oblikovati preporuke za unaprjeđenje statusa manjina te jačanje kulturne autonomije na lokalnoj razini Hrvatske i Bosne i Hercegovine. - Since the authorities closest to the citizens can respond to the needs and interests of the local community, the local government should provide key support for the implementation of minority policy. The main research question concerns the role of local government units in implementing the principle of equality and ensuring the protection of national minorities against discrimination. The tripartite typology of states' obligations in the protection of universal human rights was chosen as the theoretical framework for the research, on the basis of which proposals for strengthening the role of local government units in the protection of minority rights were offered. A comparative research method was then applied to compare the legal regulation of minorities in Croatia and Bosnia and Herzegovina. The aim is to determine which minority policy standards have been applied at the local level of the countries under consideration and to what extent they correspond to the proposed instruments for strengthening the role of local government units. Based on the research results, the purpose of this paper is to give recommendations for improving the status of minorities and strengthening cultural autonomy at the local level in Croatia and Bosnia and Herzegovina.

Struktura populističke ideologije [Elektronička građa] : Srbija 2017 / Bojan Todosijević, Ljubomir Hristić. - Graf. prikazi.
Bibliografske bilješke uz tekst ; bibliografija: str. 27-30. - Sažetak ; Summary. - U literaturi je sve prisutnije shvatanje da se populizam može tumačiti kao ide- ologija koja ima specifičnu, iako ’tanku’, sadržinu. Smatra se da to važi ne samo za političke partije i pokrete, nego i da karakteriše stavove onih koji pružaju po- dršku populističkim partijama i ličnostima. Komparativna studija izbornih si- stema (CSeS, www.cses.org) je u svoj 5. modul uključila operacionalizaciju po- pulističke ideologije kao kombinaciju tri osnovne orijentacije: negativnog stava prema manjinama i imigrantima, negativnog stava prema političkim elitama, i isključive koncepcije nacionalnog identiteta. u ovom radu analiziramo u kojoj meri takva koncepcija populističke ideologije ima empirijsku podršku na osno- vu podataka iz Srbije. Podaci su prikupljeni nakon predsedničkih izbora 2017. godine, metodom on-line anketiranja. testirana je strukturna hipoteza o među- sobnoj povezanosti teorijskih komponenti populističke ideologije. nakon toga je analizirana povezanost dimenzija komponenti populističke ideologije sa par- tijskim preferencijama. rezultati su pokazali da navedene tri komponente ne konvergiraju ka jednoj opštijoj dimenziji populističke ideologije. Zaključeno je da skala anti-elitizma, u kontekstu Srbije, jeste indikator stava prema partijama na vlasti, a ne samo populističke antipatije prema političkoj eliti. - There is a growing perception in the literature on populism that it can be char- acterized as an ideology that has a specific, albeit ’thin’, content. It is considered that this applies not only to political parties and movements, but also to the at- titudes of those who support populist parties and personalities. the Compara- tive Study of electoral Systems (CSeS, www.cses.org) included in its 5th mod- ule the operationalization of populist ideology as a combination of three basic orientations: a negative attitude towards minorities and immigrants, a negative attitude towards political elites, and an exclusive conception of national iden- tity. In this paper, we analyze the extent to which such a conception of popu- list ideology has empirical support based on data from Serbia. the data was collected after the 2017 presidential election, using an online survey method. the structural hypothesis on the interconnectedness of the theoretical com- ponents of populist ideology was tested. after that, the connection between the dimensions of the components of populist ideology and party preferenc- es was analyzed. the results showed that these three components do not con- verge towards a more general dimension of populist ideology. It was conclud- ed that the scale of anti-elitism, in the context of Serbia, is an indicator of the attitude towards the ruling parties, and not just populist antipathy towards the political elite.

PEHAR, Dražen
Republicanism as a critical idiom [Elektronička građa] : whose, whom against, and what for? / Dražen Pehar.
Bilješke uz tekst. - Bibliografske bilješke uz tekst ; bibliografija: str. 115-118. - Summary ; Sažetak. - The aim of the paper is to draw briefly the discourse-theoretical foundations to the republican political theory (section 1), with the issue of slave/slavery as a pivotal concern of social and political life (section 2), and then to chart the most interesting consequences for the contemporary versions of the theory as proposed by the key authors (closing paragraphs of section 2, and section 3). the overarching message of the paper reads that republicanism is founded on a specific view of human nature as ens loquens, or zoon logon echon, that has important implications both empirically and normatively. the third, and final, section of the paper enlists six proposals, or suggestions, to contemporary republicans for the purpose of elucidating, first, the limits of republican theory/practice, and second, its intellectual origins as well as its opposition. Sum- marily, the paper lays emphasis as well on the status of republican language as a critical idiom with its pluralist, highly contextualized, and often program- matic/engaged voices. - Svrha se ovoga ogleda sastoji u kratkome prezentiranju diskurzivno-teori- jskih zasada republikanske političke teorije (dio 1), sa temom roba/ropstva kao središnjim problemom društvenoga i političkoga života (dio 2), kako bi se potom ocrtale najzanimljivije konsekvence za suvremene verzije te teorije, kako su predložene od strane ključnih autora (završni paragrafi dijela 2, i dio 3). obuhvatna poruka ogleda glasi da se republikanizam temelji na specifičnome poimanju ljudske prirode kao ens loquens, ili zoon logon echon, što sadrži važne implikacije u i empirijskome i normativnome smislu. treći, završni dio ogle- da navodi šest prijedloga, ili sugestija, današnjim republikancima kako bi se, prvo, pojasnile granice republikanske teorije/prakse, i drugo, kako bi se pojas- nili i njezini intelektualni izvori i njezina oporba. Sveukupno, ogled naglašava status republikanskoga jezika također kao kritičkoga idioma sa pluralističkim, izrazito kontekstualnim, i često programatskim/angažiranim glasovima.

Diskurzivna analiza zakonodavnog okvira Europske unije o cirkularnoj ekonomiji [Elektronička građa] / Valentino Petrović.
Bibliografske bilješke uz tekst ; bibliografija i izvori: str. 55-59. - Sažetak ; Summary. - Dosadašnja istraživanja o razvoju cirkularne ekonomije u europskoj uniji pretežno su bila usmjerena na prednosti implementacije takvoga modela koje se najčešće dijele na okolišne i ekonomske. ovaj će rad analizirati diskurs o cirkularnoj ekonomiji s drugačijeg gledišta, onoga kojemu je u središtu ljudsko zdravlje kao presudan faktor. na temelju toga, pokušat će se odgovoriti na dva pitanja; kako su se mijenjali prioriteti i diskurs unutar zakonodavnog okvira europske unije kada je riječ o cirkularnoj ekonomiji, te kako osvijestiti aktere da prilagode svoje ponašanje i djelovanje okolišnim normama. u analizi se koriste metode analize teksta i diskursa, kojima će se adresirati dosadašnja literatura i dokumenti europske unije, prvenstveno paketi mjera o cirkularnoj ekonomiji, akcijski plan iz 2015. godine i novousvojene direktive. ujedno, isko- rištena je komparativna metoda za usporedbu ‘starih’ i ‘novih’ direktiva, odnosno diskursa u europskoj uniji i Kini, te posljednja metoda, intervju s Davorom Škrlecom, bivšim zastupnikom u europskom parlamentu i članom Kluba zastupnika Zelenih/europskog slobodnog saveza. rezultati su pokazali da je svaki novi paket europske unije bio kvalitativno precizniji, ali da se sa stajališta ciljeva izlazilo u susret implementacijskim kapacitetima država članica. na kraju, oblikovao se zasebni diskurs o cirkularnoj ekonomiji za čiju je sustavnu provedbu ipak nužno u središte postaviti pitanje zdravlja. - The latest research on circular economy development in the european uni- on were primarily directed towards the advantages of implementation of such model which are most commonly presented as environmental and economic. this paper analyzes the circular economy discourse from a different point of view, one that focuses on human health as crucial element. In line with that, the paper will answer two questions; how did priorities and discourses within the legislative framework in the european union had changed, and how to raise awareness of main actors to adapt their behaviour and actions towards en- vironmental norms. the paper uses text and discourse analysis by which the current literature and documents of the european union will be addressed, primarily the eu packages on circualr economy, 2015 action Plan and newly adopted directives. also, comparative method is used for comparison of „old“ and „new“ directives and discourses between the European union and China. The last method used is interview conducted with Davor Škrlec, former Member of European Parliament and member of Greens/European Free alliance political group. the results have shown that each new package on circular economy was more precise regarding quality but the proclaimed goals were alligned with implementation capacities of member states. thus, a new discourse on circular economy was formed but in order it to be systematically implemented there is a need to emphasize human health as its main priority.

Dysfunctionality of two-part transfer pricing in investment centers' performance assessment [Elektronička građa] / Liudmila A. Guzikova, Igor A. Nechitaylo. - Graf. prikazi.
Bibliografija: 23 jed. - Summary ; Sažetak. - The paper discusses the question of the ability of the two-part transfer pricing system to stimulate investment centers to reject projects with positive NPV and to accept projects with negative NPV when there is no external market for intermediate products. The study revealed under which circumstances investment centers can take such dysfunctional decisions and it investigated if these systems can be modified to eliminate negative effects of such circumstances. In order to solve these problems, methods of financial analysis, real options theory and theory of constraints were used and several hypothetical business situations were modelled to exemplify possible dysfunctional behavior of investment centers when strategic decisions are taken in a decentralized manner. The paper considers the reasons for taking such decisions, such as using average rates of resource costs in calculating the transfer payment, presence of the real options in related projects complex and breaking the five focusing steps of the theory of constraints. - U ovom se radu raspravlja o mogućnostima sustava dvosmjernog određivanja transfernih cijena za poticanje investicijskih centara za odbijanje projekata s pozitivnom neto sadašnjom vrijednošću, odnosno prihvaćanje projekata s negativnom neto sadašnjom vrijednošću, u slučaju kada ne postoji vanjsko tržište međuproizvoda. Utvrđuje se u kojim uvjetima investicijski centri mogu donositi tako disfunkcionalne odluke te se istražuje kako se odgovarajući sustavi mogu modificirati, kako bi se uklonili negativni efekti. Za rješavanje navedenih problema, koriste se metode financijske analize, teorije realnih opcija i teorije ograničenja te se modelira nekoliko hipotetskih poslovnih situacija, kojima se prikazuju posljedice mogućeg disfunkcionalnog ponašanja investicijskih centara, u uvjetima decentraliziranog strateškog odlučivanja. U radu se razmatraju razlozi za donošenje ovakvih odluka, kao što su korištenje prosječnih stopa troškova resursa u kalkulaciji transfernih plaćanja, prisustvo realnih opcija u povezanim projektima te narušavanje pet koraka fokusiranja u okviru teorije ograničenja.

BIRAČ, Dimitrije
Politička ekonomija Hrvatske [Elektronička građa] : obnova kapitalizma kao "pretvorba" i "privatizacija" / Dimitrije Birač.
Bibliografske bilješke uz tekst ; bibliografija: str. 93-97. - Sažetak ; Summary. - Rad se ponajviše bavi analizama hrvatskih ekonomista o procesu pretvorbe i privatizacije 1990-ih. Posljednjih desetljeća, posebno od prvih višestranačkih izbora u travnju 1990., proces političko-ekonomske transformacije presudno je utjecao ne samo na društveno-ekonomsku strukturu Hrvatske nego i na hrvatsku polit-ekonomsku misao. Pregledom znanstvenih radova hrvatskih ekonomista, polit-ekonomista i sociologa te njihovom daljnjom analizom rad ima ambiciju pridonijeti novom pristupu proučavanja procesa pretvorbe i privatizacije. Uza sve razlike u mišljenjima te istraživačkim zaključcima, hrvatski analitičari u jednom su suglasni – bez pretvorbe i privatizacije ne bi se razvio ni kapitalizam u Hrvatskoj. U ovom radu razvija se teza da je proces pretvorbe i privatizacije u suštini bio obnova kapitalizma putem primarne akumulacije kapitala. Ono što se još naziva i divljim kapitalizmom, crony, pa i tajkunskim kapitalizmom, zapravo je bio uobičajeni tijek nastanka i razvoja kapitalizma periferije. Pritom se njegova specifična osobina tiče nacionalne države kojoj je pripala uloga stvaratelja sistema i vladajuće klase, umjesto da se zbilo obrnuto – da je vladajuća klasa stvorila državu i ekonomski sistem. Istovremeno je namjera rada pokazati da nisu dovoljno precizne tvrdnje prema kojima je proces pretvorbe i privatizacije trebao i mogao biti pravedniji u slučaju pobjede druge političke opcije. Na temelju navedenog može se bolje razumjeti paradoks da je Hrvatska u proces pretvorbe i privatizacije ušla kao jedna od zemalja s najboljim pretpostavkama, a iz njega izašla kao jedan od najneuspješnijih primjera. - The paper deals with various analyses by Croatian economists of the so-called process of transformation and privatization in the 1990s. In recent decades, especially since the first multi-party parliamentary elections in April 1990, the process of political-economic transformation has not only decisively changed the socio-economic structure of Croatia, but also influenced the Croatian polit-economic thought. By reviewing works by Croatian economists, political economists and sociologists, this paper has the ambition to make a contribution to a new approach of studying the process of transformation and privatization. This paper develops the thesis that the process of transformation and privatization was essentially a restoration of capitalism through primary accumulation of capital. What is also called wild capitalism, cronyism, and even tycoon capitalism – was in fact the usual course of the emergence and development of peripheral capitalism. Its specific feature is connected with the nation-state which had the role of system-maker as well as ruling-classmaker, rather than the other way around – that the ruling class had created its own state and economic system. At the same time, we reject as simplified various conclusions that the transformation and privatization process should have been and could have been more just and fair. In the end, one can better understand the paradox of Croatia starting the process of transformation and privatization as one of the countries with the best features and finishing as one of the most unsuccessful examples.

Što donosi moderna monetarna teorija? [Elektronička građa] / Marko Grdešić.
Bibliografske bilješke uz tekst ; bibliografija: str. 113-117. - Sažetak ; Summary. - Ovaj rad daje kritički pregled Moderne monetarne teorije (MMT). Riječ je o pristupu ekonomskoj politici koji naglasak stavlja na autonomnu ulogu države, na njen monopolni položaj u sferi izdavanja novca te na mogućnost države da osigura punu zaposlenost kroz program zajamčenog zaposlenja. Rad iznosi glavne teorijske i policy elemente MMT-a, a zatim prikazuje glavne kritike koje se upućuju MMT-u iz liberalne, kejnzijanske i marksističke perspektive. Osim toga, ovaj rad raspravlja i mogućnost da periferne zemlje, poput Hrvatske, primijene ekonomske alate koje preporuča MMT. S obzirom na to da je MMT prešao s terena relativno marginalnih akademskih debata na teren šire političke javnosti, može se očekivati da će utjecati na ekonomsku agendu u narednim godinama. - This article provides an overview of Modern Monetary Theory (MMT). This approach to economic policy emphasizes the autonomous role of the state, its monopoly status in terms of issuing currency and its ability to provide full employment via a job guarantee. The article presents the main theoretical and policy elements of MMT, followed by the main criticisms stemming from liberal, Keynesian and Marxist perspectives. Additionally, this article discusses the possibility that peripheral countries, like Croatia, apply the economic tools suggested by MMT. Given that MMT has transitioned from the relatively marginal terrain of academic debates onto the terrain of more visible public discussion, one can expect that it will be able to shape the economic agenda in coming years.

Assessment of the net effect of the active labour market policy in Bulgaria [Elektronička građa] / Atanas Atanassov, Silvia Trifonova. - Graf. prikazi.
Bibliografija: 74 jed. - Summary ; Sažetak. - The assessment of the net effect of active labour market policy contributes to the effective use of public funds in order to achieve optimal results and provide opportunities for future changes in the priority areas of the employment action plans. The paper examines the basic concepts for assessing the net effect of active labour market policy and assesses the net effect of this policy in Bulgaria. In the process of assessing the impact of active labour market policy at the individual level for each program and measure included in the National Employment Action Plan in 2015 and funded from the state budget, the gross effect, deadweight effect, the substitution and displacement effects are estimated. The quasi-experimental design method is applied to assess the net effect of programs and measures on the labour market in Bulgaria. The estimation results demonstrate that the total net effect has the value of 14.5%. The net effect for women is significantly higher than for men. Regarding education, the highest net effect can be seen among those with primary or no education Regarding age, the highest net effect is observed among young people up to 24 years of age. As related to the duration of unemployment, the highest net effect can be seen among long-term unemployed people (over 24 months). In terms of working capacity, the highest net effect is observed among people with reduced working capacity. Regarding the type of settlement, the highest net effect can be seen in rural areas. The paper provides a number of conclusions and recommendations for increasing the effectiveness of active labour market policy and for improving the state of the labour market in Bulgaria. The analysis shows that in Bulgaria it is necessary to maintain the variety of different programs and measures on the labour market, covering different target groups. - Procjena neto efekta aktivne politike zapošljavanja doprinosi efektivnoj uporabi javnih sredstava, kako bi se postigli optimalni rezultati i osigurale mogućnosti budućih promjena prioritetnih područja u akcijskim planovima zapošljavanja. U ovom se radu analiziraju osnovni koncepti za procjenu neto efekta aktivne politike zapošljavanja i procjenjuju njeni neto efekti u Bugarskoj. U okviru procjene djelovanja aktivne politike zapošljavanja na individualnoj razini, za svaki program i mjeru, uključenu u nacionalni akcijski plan zapošljavanja iz 2015. godine te financiranu iz državnog budžeta, procjenjuju se ukupni, rezidualni, supstitucijski i zamjenski efekti. Za procjenu neto efekta programa i mjera na tržište rada u Bugarskoj, koristi se kvazi-eksperimentalni istraživački nacrt. Rezultati procjene govore da ukupni neto efekt iznosi 14,5%. Za žene, on je značajno veći, negoli za muškarce. S aspekta obrazovanja, najveći neto efekt odnosi se na osobe s osnovnim, ili bez formanog obrazovanja. Kada se promatra dob, najveći neto efekt se primjećuje za mlade do 24 godine starosti. Vezano uz trajanje nezaposlenosti, najveći se neto efekt može primijetiti kod dugoročno (dulje od 24 mjeseca) nezaposlenih osoba. Što se tiče sposobnosti za rad, najveći neto efekt je prisutan kod osoba sa smanjenom sposobnošću, a s aspekta vrste naselja – u ruralnim područjima. U radu se iznosi određeni broj zaključaka i preporuka za povećanje efektivnosti aktivnih politika zapošljavanja i unapređenje tržišta radne snage u Bugarskoj. Analiza pokazuje da je u Bugarskoj potrebno održavati različite programe i mjere na tržištu rada, kojima se ciljaju i različite ciljne skupine.

PETROV, Emanuel
Evanđeoski pristup Ivana Pavla II. migracijama kao izvoru blagostanja [Elektronička građa] / Emanuel Petrov.
Bibliografske bilješke uz tekst. - Sažetak ; Summary. - Polazeći od temeljnog stava da Crkva postoji kako bi evangelizirala, Ivan Pavao II. u svjetlu evanđeoskog čovjekoljublja i solidarnosti trasira put Crkve u odnosu prema fenomenu selilaštva na početku trećeg tisućljeća. Riječ je o zalaganju za dostojanstvo svakog konkretnog čovjeka i njegove obitelji, koje izvire iz čovjekove bogolikosti. Takav stav Sveti Otac beskompromisno zastupa u svojim poslanicama za Svjetski dan selilaca. U skladu s tim Crkva i svi njezini članovi, žele li ostati vjerni Kristovom poslanju, ne smiju biti slijepi na vapaje i potrebe migranata i njihovih obitelji, nego su dužni autentično živjeti Kristovu istinu, tj. evanđeoski intervenirati i iskazati solidarnost, te tako u dijalogu svjedočiti i navijestiti puninu spasenja pridržanu Crkvi po Kristu. Selilaštvo u tom smislu nije prijetnja, nego prilika za napredak i rast blagostanja ljudske obitelji. Shodno tome nezaobilazan put Crkve trećeg tisućljeća jest kultura života, tj. kultura dobrodošlice, integracije obitelji te humanog pluralizma. - Starting from the fundamental view that the Church exists in order to evangelize, John Paul II, in the light of evangelical philanthropy and solidarity, traces the Church's path in relation to the phenomenon of migration at the beginning of the third millennium. It is about pleading for the dignity of each particular man and his family, which springs from man's godlikeness. Such an attitude is uncompromisingly advocated by the Holy Father in his epistles for the World Day of Migrants. Accordingly, the Church and all its members, if they wish to remain faithful to Christ's mission, must not be blind to the cries and needs of migrants and their families, but must authentically live the truth of Christ, i.e. evangelically intervene and show solidarity, and thus in dialogue to bear witness and proclaim the fullness of salvation reserved to the Church through Christ. Migration in this sense is not a threat, but an opportunity for the progress and growth of the well-being of the human family. Consequently, the unavoidable path of the Church of the third millennium is the culture of life, i.e. the culture of welcome, family integration and humane pluralism.

Mobility and working opportunities in the EU and Slovakia [Elektronička građa] / Ľubica Bajzíková, Peter Bajzik. - Graf. prikazi.
Bibliografija: 32 jed. - Summary ; Sažetak. - Current globalisation processes witness the mobility and migration of labour as their characteristic features. The free movement of people and workers is one of the rights of citizens of the European Union (EU), and includes the right to move, to reside and to work in an EU member state without discrimination. The aim of this paper is to analyse the labour mobility within the EU with special attention to Slovakia. In its historical development, Slovakia belonged to countries with population migrating predominantly to foreign countries and was not a traditional destination country for migrants. However, today it has gradually become a state that employs foreign labour, especially in production plants. This change has not only been contributed to by Slovakia’s accession to the EU, but especially by the economic development of the state and the creation of new job opportunities for both domestic and foreign labour. The study analyses the intra-mobility in Slovakia and focuses on analysis of the trends in employment of foreign workers from EU and non-EU member states between 2007 and 2019. For the purposes of this paper, data were extracted from a relatively large number of prominent sources, for example: the European Commission, Eurostat, and the International Labour Organization (ILO) reports, and the Slovak Statistical Office resources related to labour mobility. In the desk research, the collected information were analysed and subjected to critical multidimensional assessment from quantitative, absolute, and relative, as well as cross-sectional perspectives. Special attention was paid to analysis of documentation that accompanied these data. The significance of the examined topic is underlined by the fact that Slovakia is currently a recipient of foreign labour due to insufficient qualification of domestic labour. - Procesi globalizacije donose mobilnost i migraciju radne snage kao jednu od svojih karakteristika. Slobodno kretanje ljudi i radnika je jedno od prava građana Europske Unije (EU) te uključuje pravo na mobilnost, boravak i zaposlenje u bilo kojoj članici EU-a, bez diskriminacije. Cilj ovog rada je analiza radne mobilnosti unutar EU-a, s posebnim naglaskom na Slovačku. U svom povijesnom razvoju, Slovačka je pripadala zemljama, čije je stanovništvo uglavnom sesilo u strane države te nije predstavljala zemlju, koja bi primala doseljenike. Međutim, ona je postepeno postala država, u kojoj se zapošljavaju strani radnici, posebno u proizvodnim pogonima. Ovoj promjeni nije doprinijelo samo slovačko pristupanje EU-u, već posebno i gospodarski razvoj te stvaranje novih radnih mjesta, kako za domaće, tako i strane radnike. U radu se analizira interna mobilnost u Slovačkoj te se fokusira na analizu trendova zaposlenosti stranih radnika iz država-članica EU-a, kao i izvan EU-a, između 2007. i 2019. godine. Za izradu rada, korišteni su podaci iz velikog broja značajnih izvora (izvješća Europske komisije, Eurostata, Međunarodne organizacije rada, Slovačkog statističkog ureda, koja se odnose na radnu mobilnost). U okviru istraživanja za stolom, prikupljene informacije su analizirane i kritički procijenjene s više perspektiva: kvantitativne, apsolutne, relativne i kros-sekcijske. Posebna se pozornost obraća analizi prateće dokumentacije. Značaj analizirane teme pojačava činjenica da je Slovačka trenutno primateljica strane radne snage, zbog nedovoljnih kvalifikacija domaćih radnika. Stoga se uvode i nove pravne mjere za ubrzavanja procesa zapošljavanja, uklanjanje administrativnih zapreka i ubrzavanje procesa prilagodbe novim radnim uvjetima, u suradnji s poslodavcima, a što se posebno odnosi na radnike iz zemalja izvan EU-a. Nadalje, zapošljavanje radnika iz trećih zemalja u Slovačkoj je relativno zahtjevan i dugotrajan proces.

Zaštitni i rizični faktori u razvoju karijere te moguće intervencije u školskom kontekstu [Elektronička građa] / Iva Šverko, Toni Babarović.
Bibliografija: str. 367-374. - Sažetak ; Summary. - U ovom radu opisuju se i sistematiziraju zaštitni i rizični faktori koji mogu djelovati na profesionalni razvoj pojedinca. Ponuđena je konceptualizacija zaštitnih i rizičnih faktora unutar tri domene – osobne, relacijske i situacijske. Osobni su faktori psihološke osobine za koje je u literaturi potvrđeno da imaju utjecaja na profesionalni razvoj, poput ekstraverzije, savjesnosti, orijentacije prema budućnosti, optimizma, fleksibilnosti, otpornosti na stres, samoefikasnosti, kognitivnih kapaciteta ili pak zdravlja pojedinca. Relacijski faktori obuhvaćaju socijalne utjecaje koji mogu djelovati pozitivno ili negativno na profesionalni razvoj, počevši od utjecaja roditelja, vršnjaka te društva u cjelini, primjerice kroz socijalnu podršku za razvoj karijere, ali i roditeljske i odgojne stilove. Situacijski faktori predstavljaju različite vanjske utjecaje koji mogu djelovati na razvoj karijere, od kojih su u literaturi jasno prepoznati socioekonomski status te prilike u mjestu stanovanja pojedinca. U radu se razmatraju utjecaji zaštitnih i rizičnih faktora na razvoj karijere i prikazuju se dosadašnja istraživanja u tom području. Također, u radu se upućuje na dostupne alate za profesionalno usmjeravanje adolescenata koji mogu ublažiti neželjeno djelovanje rizičnih faktora. - This paper gives a review and new systematization of protective and risk factors that influence an individual's career development. According to the proposed conceptualization, protective and risk factors in career arise from personal, relational, and situational domains. Personal factors are psychological traits that have been evidenced in the literature to influence career development, such as extraversion, conscientiousness, future orientation, optimism, flexibility, stress resilience, selfefficacy, cognitive capacity, or the health of an individual. Relational factors include social influences that can have either positive or negative effect on career development, starting with the influence of parents, peers, and society, and manifest through social support and different relational styles. Situational factors represent different external influences that can influence career development, of which the socio-economic status and opportunities in the individual's place of residence are clearly recognized in the literature. The paper elaborates on the effects that protective and risk factors have on career development. Also, the paper points to available tools for career counselling of adolescents that can mitigate the undesirable effects of risk factors.

The effect of product innovation on the export performance of Kosovo SMEs [Elektronička građa] / Gezim Jusufi, Fatos Ukaj, Suada Ajdarpašić. - Graf. prikazi.
Bibliografija: 62 jed. - Summary ; Sažetak. - The aim of the paper is to provide a better understanding of factors influencing product innovations that are important to SMEs’ exporting activities. A probit model is used to analyse the innovation pattern in 100 Kosovo manufacturing and exporting SMEs. They export to the EU and regional countries’ markets. Our data shows that there is a link between the type of product innovation and the increase in exports. Incremental innovation shows a strong positive relationship with export growth of these SMEs, a result should prove helpful to both researchers of SME product innovation and managers of exporting SMEs. This study addresses the current gap that is present in the Western Balkan literature by evaluating the impact of product innovation on SMEs export performance. - Cilj ovog rada je pružiti bolje razumijevanje čimbenika, koji utječu na inovacije proizvoda, značajne za izvozne aktivnosti malih i srednjih poduzeća (MSP-a). Probit modelom se analizira 100 MSP-a s Kosova, koji izvoze na tržišta EU-a i država u regiji. Empirijski dokazi ukazuju na postojanje veze između tipa inovacije proizvoda i povećanja izvoza. Inkrementalna inovacija pokazuje snažnu pozitivnu vezu s rastom izvoza ovih MSP-a. Dobiveni rezultati mogu pomoći istraživačima inovacije proizvoda u MSP-ovima i menadžera izvoznika - MSP-ova. Studijom se postiže znanstveni doprinos, koji nedostaje u regionalnoj literaturi, a povezan je s djelovanjem inovacije proizvoda na rezultate izvoza MSP-ova.

Analiza financijskih izvještaja u funkciji donošenja kvalitetnijih poslovnih odluka [Elektronička građa] / Željko Tintor. - Graf. prikazi.
Bibliografija: 10 jed. - Sažetak ; Summary. - Adequate information background for interested users is required for business planning and running. Informing users means presenting them with relevant and reliable information in a recognizable form and content, understandable to the intended users. Most of this information comes from accounting. The final product of the accounting process is a set of statements called financial statements. They report on the state of the company and business performance and warn of potential problems. The financial statements drawn up by the entities defined in the Accounting Act are balance sheet, income statement, cash flow statement, statement of changes in equity and notes to the financial statements. Financial reporting must provide: reliable information for management decision-making, usable information for current and potential investors and lenders to make investment and loan decisions, information about entrepreneur’s resources and their sources, transactions that affect changes in resources and sources, business performance information over a period of time, as well as information to experts who want to study the state and business of the past in connection with planning, etc. In addition to owners and management, the information about the status and operations of the company may be of interest to other groups, such as business partners, investors, banks, government institutions, etc. With respect to the reasons and motives for observation, each of these groups is focused on certain aspects of financial information. For those with accounting knowledge, a set of financial statements is understandable, and if audited by independent auditors, it is also a reliable source of information for their needs. However, many people are not accounting professionals, and they require proper interpretation of the financial statements. Interpretation involves the analysis of financial statements using a complex financial analysis instrument.

ERCEGOVAC, Roberto
Bank specific determinants of EU banks profitability after 2007 financial crisis [Elektronička građa] / Roberto Ercegovac, Ivica Klinac, Ivica Zdrilić. - Graf. prikazi.
Bibliografija: 42 jed. - Summary ; Sažetak. - The basic purpose of the paper is to research determinants on profitability indicators of the banks in the European Union. Analysed bank profitability indicators considered as a standard are: the return on total bank assets (ROA) and return on total bank equity (ROE). The research model of bank profitability determinants is developed by analysing the systemically important, quoted banks in the European Union, in the 2007–2019 period, by using an adequate panel data analysis technique. The empirical evidence is in line with the initial assumptions: the efficiency of the banking firm, measured by the cost to income ratio and the non-performing loans ratio, has a significant influence on bank profitability, both on ROA and ROE. In the post-crisis period, banking firms ask for efficient cost management in achieving performance objectives. Additional important empirical results of research are the absence of impact of assets size and regulatory capital ratio on profitability indicators. The most important contribution of the paper is related to the sample definition, variable selection and explanatory power of the presented model in explaining global banking tendencies. - Temeljni cilj ovog rada je istražiti odrednice indikatora profitabilnosti banaka u Europskoj Uniji. Standardni pokazatelji profitabilnosti banaka su povrat na ukupnu imovinu banke (ROA) i povrat na ukupnu vlastitu imovinu banke (ROE). Istraživački model odrednica bankovne profitabilnosti razvijen je analizom sistemski značajnih banaka u Europskoj Uniji, listanih na tržištima kapitala, u periodu od 2017. do 2019. godine, korištenjem odgovarajuće tehnike analize panel podataka. Rezultati empirijskog istraživanja su u skladu s inicijalnim pretpostavkama: efikasnost banaka, mjerena odnosom troškova i prihoda te odnosom nenaplativih kredita, ima značajan utjecaj na profitabilnost, kako na ROA, tako i na ROE. U post-kriznom periodu, banke su orijentirane na efikasnost upravljanja troškovima, kako bi postigle svoje poslovne ciljeve. Dodatni značajni rezultati istraživanja odnose se na nepostojanje utjecaja veličine imovine te udjela regulatornog kapitala na indikatore profitabilnosti. Najznačajniji doprinos ovog rada odnosi se na definiranje uzorka, izbor varijabli i snagu predviđanja prezentiranog modela u objašnjavanju globalnih tendencija u bankarstvu.

BRUŽA, Dino
The banking development within the framework of financial globalization [Elektronička građa] / Dino Bruža, Luka Latkovich. - Graf. prikazi.
Bibliografija: 16 jed. - Summary ; Sažetak. - The concept of a bank has a long history of origin, but a short history in relation to as it is known today. The first traces of banking can historically be placed at a time when money was deposited with jewelers, but over time, the practice of lending surplus money has evolved, which is why its concept of commerce has changed. The subject of this study and research is the bank, primarily as a joint stock company. It reveals issues of functioning banks and banking, the relationship between the bank and other financial institutions, the financial and banking system, and the role and meaning of non-bank financial intermediaries. The purpose of this paper is to highlight the role and importance of banks in business, and to discover the degree of influence on other institutions. By elaborating on labor issues, it highlights their economic importance in financial globalization. The aim of this paper is to get to know its main tasks for which it was founded and the process of transformation of banking services in the global framework, especially in entrepreneurship. A research hypothesis has been formed: financial globalization affects the rapid development of banking, and reveals the great influence of the banking sector on other institutions. During this research several basic scientific methods were used (compilation method, descriptive method, specification and generalization methods and comparison method). Attention is placed on the comparison of the role and importance of the banking industry in the past and in the modern business world. The emphasis is placed on comparing the role and importance of the banking sector in the past and in the modern business world. - Banka ima svoju dugu povijest nastanka, ali u odnosu na to kratku prošlost kakvu je svijet poznaje danas. Prvi tragovi bankarstva se mogu povijesno smjestiti u doba kada se novac polagao na čuvanje kod zlatara, ali tijekom vremena se razvila praksa pozajmljivanja viškova novca, zbog čega se mijenja i njezin koncept poslovanja. Predmet ovog istraživanja jest banka, kao dioničko društvo. Otkrivaju se odgovori vezani za pitanja o funkcioniranju banaka i bankarstva, objašnjavaju se odnosi banke i ostalih financijskih institucija, financijskog i bankarskog sustava te se iznosi uloga i značenje nebankarskih financijskih posrednika. Svrha rada jest ukazati na ulogu i značaj banaka u poslovanju i otkriti stupanj utjecaja na druge institucije. Elaborirajući izneseno, naglašava se ekonomski značaj u financijskoj globalizaciji. Cilj rada jest objasniti proces transformacije bankarskih usluga u globalnom okviru i poduzetništvu. Formirana je istraživačka hipoteza: financijska globalizacija utječe na brži razvoj bankarstva i na veći utjecaj bankarskog sektora na druge institucije. Tijekom istraživanja korišteno je nekoliko osnovnih znanstvenih metoda (metoda kompilacije, metoda deskripcije, metoda specifikacije i generalizacije te metoda usporedbe). Naglasak je stavljen na usporedbu uloge i značaja bankarskog sektora u prošlosti i u suvremenom poslovnom svijetu. Analizom razvoja bankarstva i poduzetništva se formira kvalitetan okvir za daljnje istraživanje, a dodana vrijednost čitatelju u pogledu boljeg razumijevanja razlike među financijskim institucijama, čemu doprinose i izdvojeni praktični primjeri odabranih globalnih banaka na globalnom tržištu.

PRIMORAC Krmpotić, Martina
Financijska pismenost - jedan od temelja poduzetničkog učenja [Elektronička građa] / Martina Primorac Krmpotić. - Graf. prikazi.
Bibliografija: 9 jed. - Sažetak ; Summary. - U Hrvatskoj su odrasli građani prezaduženi, a mladi financijski nepismeni te je evidentna potreba za financijskim obrazovanjem. Međunarodno istraživanje OECD-a PISA 2012 pokazalo je da hrvatski petnaestogodišnjaci nisu sposobni donijeti ispravnu financijsku odluku i planirati budućnost. Različita istraživanja financijske pismenosti u Republici Hrvatskoj pokazala su da je prosječna ocjena financijske pismenosti poražavajuća. Najnižu pismenost imaju mlađi od 19 godina. U sklopu istraživanja uobičajeno se mjere tri osnovne kategorije: financijsko znanje, financijsko ponašanje i odnos prema novcu, a rezultati pokazuju da, premda se mladi od najranije dobi susreću s novcem, o novcu se ne razgovara u obitelji, vrtiću, školi ili fakultetu. Osnovno financijsko obrazovanje nije ponuđeno u obrazovnom sustavu u Hrvatskoj ni na kojoj razini. Posljedica je da mladi ne znaju procijeniti izazove i rizike na financijskom tržištu, što dovodi do loših poslovnih odluka, pada prihoda i prevelike zaduženosti. U nastojanju da se to promijeni, a u skladu s dva dokumenta Vlade Republike Hrvatske (Odluku o donošenju programa međupredmetnih i interdisciplinarnih sadržaja građanskog odgoja i obrazovanja za osnovne i srednje škole i Nacionalni strateški okvir financijske pismenosti potrošača za razdoblje od 2015. do 2020. godine) učenicima trećeg i četvrtog razreda Hotelijersko-turističke škole uveden je fakultativni predmet Financijska pismenost. U ovom su radu prezentirana očekivanja učenika koji su prepoznali vrijednosti nastavnog sadržaja, opisan je nastavni proces i načini učenja putem izvannastavnih aktivnosti. Prikazan je sadržajni okvir predmeta distribuiran po modulima u skladu s Odlukom o donošenju kurikuluma međupredmetne teme Poduzetništvo za osnovne i srednje škole, zatim metode procjene znanja i usporedba rezultata anketa učenika koji pohađaju financijsku pismenost i učenika koji je ne pohađaju. - The fact that the adult Croatian citizens are severely indebted and the youth is financially illiterate, created the need for financial education. OECD-a PISA 2012 international research showed that Croatian fifteen-year-olds do not know how to make a sound financial decision or plan their future. Various research studies conducted in the Republic of Croatia indicated a very low average rate of financial literacy, the lowest being recorded among the population younger than 19. The research ubiquitously measures three basic categories: financial knowledge, financial conduct and attitude toward money. The results show that the finances are not discussed either in the family circle or in school or at university. Basic financial education is not a part of the curriculum at either of the educational levels. Consequently, young people do not know how to estimate potential risks and meet the challenges of the financial market, which leads to making bad business decisions, profit decrease and debts. Trying to change that situation, the School of Hotel Management and Tourism in Zagreb has implemented Financial Literacy as an elective school subject in the third and the fourth year curriculum, in accordance with two documents issued by the Government of the Republic of Croatia (Decision on Implementing Interdisciplinary and Cross-Curricular Topics of Civic Education in Primary and Secondary Schools and National Strategic Outline of Financial Literacy of Consumers for the Period between 2015 and 2020). This paper encompasses the expectations of students who recognized the value of the subject matter, describes the educational process and learning methods used in extracurricular activities: visiting financial institutions.

Policies for promoting diaspora investment in countries of origin [Elektronička građa] / Sanja Franc, Marina Perić Kasel, Ivona Škreblin Kirbiš. - Graf. prikazi.
Bibliografija: 32 jed. - Summary ; Sažetak. - Investments from the diaspora and transnational entrepreneurship represent significant areas for potential contribution to national development. Due to the fact that diaspora members have the ability to connect with a wide range of potential partners and supporters in both their countries of origin and countries of residence, and thus create opportunities for investment, trade and outsourcing, developing countries which seek human and financial capital should put more focus on facilitation and promotion measures for collaboration with the diaspora. The main aim of this paper is to define and discuss most commonly used policy measures for promoting diaspora investments and transnational entrepreneurship in developing countries and giving recommendations for diaspora engagement. The analysis indicates that policy measures and the degree to which countries have begun to engage their diaspora vary, while most of them still miss an adequate institutional framework for promoting transnational networks which can be an important channel for fostering business development, job creation and innovation. - Ulaganja dijaspore i transnacionalno poduzetništvo predstavljaju značajna područja potencijalnog doprinosa nacionalnom razvoju. S obzirom na činjenicu da dijaspora ima više mogućnosti povezivanja sa širokim spektrom potencijalnih partnera, kako u svojim zemljama podrijetla, tako i u zemljama imigracije te time i stvaranja prilika za ulaganja, trgovinu i outsourcing, zemlje u razvoju kojima nedostaje ljudskog i financijskog kapitala trebale bi se više usmjeriti na projekte i mjere poticanja suradnje s dijasporom. Glavni cilj ovog rada je definirati i raspraviti glavne i najčešće korištene mjere politika za poticanje ulaganja dijaspore i transnacionalnog poduzetništva u zemljama u razvoju sa svrhom davanja preporuka za uključivanje dijaspore. Provedena je analiza ukazala da su mjere poticanja i stupanj uključivanja dijaspore različiti među zemljama, a u većini njih i dalje nedostaje odgovarajući institucionalni okvir za promicanje transnacionalnih mreža koje mogu biti važan kanal razvoja poduzetništva, radnih mjesta i inovacija.

BRAČUN, Sanja
Utjecaj Fin-Tech kompanija na digitalnu transformaciju bankarstva u Hrvatskoj [Elektronička građa] / Sanja Bračun, Krešimir Turkalj. - Graf. prikazi.
Bibliografija: 10 jed. - Sažetak ; Summary. - Digitalna transformacija financijskog sektora na globalnom tržištu snažno napreduje. Fin-Tech kompanije sve više konkuriraju ili čak u potpunosti zaobilaze postojeći financijski sektor, primarno banke. Taj trend vidljiv je i u Republici Hrvatskoj, gdje se sve više pojavljuju nova poduzeća i njihovi inovativni financijski proizvodi. U cilju provjere spremnosti hrvatskih banaka na digitalnu transformaciju te implementaciju novih proizvoda i usluga, kroz provedeno kvalitativno istraživanje (intervjui s deset relevantnih sugovornika iz područja bankarstva i Fin-Tech kompanija) provjeren je utjecaj Fin-Tech kompanija koji su van bankarskog sektora, na sam bankarski sustav. Dodatna je pozornost tijekom istraživanja posvećena procjeni jesu li banke i Fin-Tech kompanije na hrvatskom tržištu prepoznale aktualne potrebe svojih klijenata, koliko im se dobro prilagođavaju te mogu li banke i dalje biti lideri u digitalnoj transformaciji Republike Hrvatske. Što se tiče prilagođavanja potrebama klijenata, manji dio sudionika istraživanja smatra kako će se portfelj usluga banaka tek nadopunjavati novim proizvodima i uslugama, dok ipak veći dio sudionika istraživanja smatra kako će u idućih 5 godina, postojeće prvenstveno platno prometne usluge banaka i kartičarskih kuća biti zamijenjene posve novim poslovnim modelima. Predstavnici banaka uočavaju jak utjecaj Fin-Tech kompanija na globalnom tržištu, no smatraju da u Republici Hrvatskoj oni ipak imaju manji utjecaj. Također, smatraju da se banke generalno dobro prilagođavaju novoj situaciji te da će i dalje ostati lideri digitalne transformacije. Tu poziciju zadržat će prvenstveno zbog svoje veličine i količine kapitala kojom raspolažu u procesu izgradnje percepcije sigurnosti svog poslovanja koja je hrvatskim korisnicima i dalje iznimno bitna. - The digital transformation of the financial sector is making strong progress in the global market. Fin-Tech companies are increasingly competing with, or even completely bypassing the existing financial sector, primarily banks. This trend is evident also in the Republic of Croatia, where new companies and their innovative financial products are increasingly emerging. In order to verify the readiness of Croatian banks to digital transformation and the implementation of new products and services, a qualitative research has been carried out (interviews with ten relevant respondents in the banking and Fin-Tech companies) to check the impact of Fin-Tech companies outside the banking sector on the banking system itself. During the research, particular attention was given to assessing whether banks and Fin-Tech companies on the Croatian market recognized the current needs of their clients, how well they adapted to their needs and whether banks can continue to be leaders in the digital transformation of the Republic of Croatia. As far as customer needs are concerned, a minor part of the respondents believe that the portfolio of banking services will merely be supplemented with new products and services, while most of the respondents believe that in the next 5 years the existing money transfer and card-based banking services will be replaced by completely new business models. Bank representatives note the strong influence of Fin-Tech companies on the global market but believe they still have a minor influence in the Republic of Croatia. They also believe that the banks are generally adapting well to the new situation and will continue to be leaders of digital transformation. They will retain this position primarily because of their size and the amount of capital they have at disposal in the process of building the perception of the safety of their business, which remains extremely important for Croatian clients.

Model javno privatnog partnerstva kao uspješna metoda provođenja projekta lokalne samouprave [Elektronička građa] / Rudi Štekl. - Graf. prikazi.
Bibliografija: 6 jed. - Sažetak ; Summary. - Strateško partnerstvo ili javno-privatno partnerstvo (u daljnjem tekstu: JPP) kao model dugoročne suradnje između javnoga i privatnog sektora sve više dobiva primjenu u današnjem nepredvidivom vremenu zbog brzine i učinkovitosti pripreme te provedbe raznih projekta. U lokalnim i regionalnim aktivnostima gdje se javni sektor suočava s raznom problematikom realizacije tuzemnih i EU projekta, model JPP je primjer kako se privatni sektor svojom brzom i vještom prilagodbom može uključiti u rješavanje nepremostivih izazova odnosno aktivnosti. Cilj ovoga rada je objasniti teorijski značaj modela JPP s posebnim naglaskom na lokalnu i regionalnu samoupravu te je svrha objasniti njegove pozitivne i negativne aspekte. Teorijski okvir rada daje isto tako jasnu definiciju JPP ili strateškog partnerstva te objašnjava njegovu sve veću ulogu i značaj u Hrvatskoj. Kroz rad je prikazan konkretan primjer modela JPP jedne lokalne samouprave i Visokoobrazovne institucije iz Zagreb. Navedeni primjer prikazan je kao model strateške suradnje te kako se može doći do učinkovitije i efikasnije javne usluge kao što je studiranje u jednom gradu. Uloga, važnost i značaj ovakvih i sličnih projekta sve je više izražena upravo u vidu potreba lokalnog stanovništva koji su u konačnici oni koji kreiraju ponudu te zahtijevaju za svoj novac najvišu razinu javnih usluga u svojim lokalnim sredinama. - Strategic partnerships or public-private partnerships (hereinafter referred to as PPPs), as a model for long-term cooperation between the public and private sectors, are increasingly being applied in today's unpredictable times due to the speed and efficiency of preparation as well as implementation of various projects. In local and regional activities where the public sector is confronted with various issues related to the implementation of domestic and EU projects, the PPP model is an example of how the private sector can be involved in addressing insurmountable challenges and activities with its rapid and smart adaptation. The aim of this paper is to explain the theoretical significance of the PPP model with particular emphasis on local and regional self-government, as well as to demonstrate its positive and negative aspects. The theoretical framework provides a clear definition of PPP or strategic partnership and explains its growing role and importance in Croatia. A concrete example of a PPP model of a local government and a Higher Education Institution from Zagreb is presented through the paper. The above example is presented as a model of strategic cooperation and shows how a more efficient and effective public service such as studying in one city can be obtained. The role and importance of such and similar projects is increasingly expressed precisely in the light of the needs of the local population, who are ultimately the ones creating the offer and demanding for their money the highest level of public services in their local communities.

Međuutjecaj klimatskih promjena i turističke djelatnosti - narativni pregled [Elektronička građa] / Aleksandar Racz.
Bibliografske bilješke na kraju teksta. - Sažetak ; Abstract. - Turizam je jedna od najbrže rastućih globalnih gospodarskih aktivnosti te ima važnu ulogu u nacionalnim i lokalnim gospodarstvima. Globalne klimatske promjene, kao i održivi razvoj kroz društveno i ekološki odgovorno poslovanje u turizmu aktualno je područje istraživanja tek manjeg broja znanstvenika diljem svijeta. Nedostatak šireg interesa izostaje iako je ekspertna grupa okupljena oko Međunarodnog panela za klimatske promjene (IPCC) još sredinom drugog desetljeća 20. stoljeća potvrdila „s gotovo punom sigurnošću da ljudske djelatnosti dominantno uzrokuju globalno zatopljenje, koje dovodi do višestrukih manifestacija klimatskih promjena” te tako klimatske promjene prestaju biti tek predmet akademskog istraživanja, već su u ovom trenutku, uvažavajući i sve druge ekološke probleme, postale najveći izazov i prijetnja opstanku ljudske civilizacije, s brojnim posljedicama i vrlo širokim utjecajem na gotovo sve aspekte ljudskoga života, pri čemu nedvojbeno utječu i ekonomiju, socijalne aspekte i odnose u društvu, a tek jednim dijelom, iako vrlo važnim, i na turizam kao gospodarsku granu. Između turizma i klimatskih promjena postoji dvosmjerna međusobna veza. S jedne strane turizam uvelike ovisi o klimatskim elementima, na primjer temperaturi, padalinama i satima insolacije u danu, odnosno o klimi u cjelini kao važnom čimbeniku, a s druge strane turizam u cjelini, a posebice transport povezan s dolascima turista na destinacije i njihovim odlascima te turistički smještaj per se znatno pridonose globalnom zatopljenju kroz emisije stakleničkih plinova i znatni ugljikov otisak turističke djelatnosti. - Tourism is one of the fastest growing global economic activities and plays a significant role in national and local economies. Global climate change, as well as sustainable development through socially and environmentally responsible tourism business, is a current field of research for only a small number of scientists worldwide. There is a lack of broader interest, although an expert group gathered around the International Panel on Climate Change (IPCC) in the mid-1990s of the 20th century confirmed “with almost complete certainty that human activities are the dominant cause of global warming, leading to multiple manifestations of climate change.” In this way, climate change is no longer the subject of academic research only, but taking into account all other environmental problems, climate change has currently become the greatest challenge and threat to the survival of human civilization, with numerous consequences and a very wide impact on almost all aspects of human life. Climate change undoubtedly also affects the economy, social aspects and relationships in society, and only partly, though very importantly, tourism as an economic branch. There is a two-way relationship between tourism and climate change. On the one hand, tourism largely depends on climate elements such as temperature, precipitation and hours of insolation in the day, that is, on the climate as a whole as an important factor. On the other hand, tourism as a whole, especially transport related to tourist arrivals and departures and tourist accommodation per se, contribute significantly to global warming through greenhouse gas emissions and a significant carbon footprint of tourism. The effects of climate change lead, among other things, to increased risk of floods and droughts, melting of glaciers, rising sea levels, loss of biodiversity, various threats to human health, changing relationships in the social sphere, as well as causing significant damage to all economic activities.

Nacionalni park Plitvička jezera - zaštita i(li) razvoj koreničkoga kraja - komunalna infrastruktura kao podloga za turistički razvoj (1949.- 1990.) [Elektronička građa] / Ivan Brlić. - Ilustr.
Bibliografske bilješke uz tekst ; bibliografija i izvori: str. 437-438. - Sažetak ; Summary. - Današnja turistička uspješnost najstarijega hrvatskoga nacionalnog parka rezultat je brojnih dugotrajnih gospodarskih, ekonomskih i infrastrukturnih projekata koji svoj početak imaju još u vremenu Austro-Ugarske. Važnu ulogu u nastanku i razvoju turizma na području Plitvičkih jezera imala je i lokalna zajednica, odnosno područje bivše općine Titova Korenica. Rad stoga prvenstveno prikazuje važne komunalne projekte koji su u većoj mjeri pratili znatan razvoj turizma u novoproglašenom nacionalnom parku i njegovoj bližoj okolici. Ovdje se u prvom redu misli na razdoblje nakon Drugoga svjetskog rata, odnosno socijalističku Jugoslaviju, kada je uz novu rigidnu političku paradigmu trebalo nastojati ostvarivati nove oblike gospodarskoga razvoja prateći suvremene turističke razvojne silnice. - Communal construction formed the basis of tourism and economic development in the Plitvice region during the era of Socialist Yugoslavia; it was torn between realistic financial capabilities and political-economic ambitions. The Plitvice Lakes area and its vicinity needed to be rebuilt after the human and material losses sustained during World War II. The foundations were shaky; the inherited difficulties in the development of rural modernisation inherent to Lika were especially pronounced and were a major stumbling block to the development of the Korenica and Plitvice region. Local political and economic entities were aware of the development potentials, but were tied to the socialist paradigm of progress through five-year plans during the 1950s and 1960s. Communal infrastructure played an important role in this context; it needed to be rebuilt from scratch so that it could keep up with the real needs of the population and business entities under social ownership. The construction of communal infrastructure itself was mostly concentrated in the National Park area, though certain difficulties appeared in its implementation even there, and remain present to some extent today. Despite the difficulties faced by the officials of Titova Korenica Municipality, the development of tourism in Plitvice Lakes was never in question. The reason behind the specific approach to Plitvice Lakes National Park is that this protected area was one of the key development resources of national interest, and has remained such to this day. On the other hand, the surrounding municipal area, like the National Park area itself, never developed an even approximately similar historical dynamic. The 1970s and 1980s brought the most visible improvements in the strategic planning of the economic development of tourism in Plitvice Lakes, which was then turned over to public communal projects and new forms of protection of certain areas of the National Park.

Wellness tourism as one of its components, and especially medical tourism, is an organized implementation of preventive healthcare and curative programs with the purpose to prevent disease, preserve and improve health, the service quality of which affect the diversity of the overall tourism product, and thus the better recognizability of the destination in an increasingly demanding market. The aim of the paper is to analyze expectations and perception of service customers were researched by the use of the modified SERVQUAL model. The study was conducted at the Thalasso Wellness Centre in Opatija on a random sample of 87 respondents and analyse with method of descriptive and bivariate statistical analysis. The study results confirmed the empirical assumption of the adequacy of using the SERVQUAL model for measuring the quality of wellness services since a clear picture of the overall quality of wellness services was obtained. The results unambiguously point to the existence of a gap between the perception and expectations of customers. Given that the highest average perception ratings went to tangible and reliable dimensions, and the lowest average ratings to compassion or empathy dimensions, the largest gap was also established in these dimensions. The results of the empirical research can serve the management of the institution as an incentive for justifying the continuous research of wellness service quality, the satisfaction of wellness service users and job satisfaction of the wellness centre staff, by using other methods and models as well.

Competitiveness of selected South-Eastern European countries in European Union wood flooring market [Elektronička građa] = Konkurentnost odabranih zemalja jugoistočne Europe na tržištu drvenih podova Europske unije / Branko Glavonjić, Aleksandra Lazarević, Leon Oblak, Miljan Kalem, Predrag Sretenović. - Graf. prikazi.
Bibliografija: 21 jed. - Abstract ; Sažetak. - Selected South-Eastern European countries (SEEC - Albania, Bosnia and Herzegovina, Croatia, Montenegro, North Macedonia, Serbia and Slovenia) represent significant producers and exporters of wood flooring in Europe. In 2018, 9.4 % of Europe’s wood flooring production originated from this region. The region is a net exporter of wood flooring since it exports over 50 % of total production. The most important market for the export of wood flooring is the European Union with a share of over 60 % in total exports. Trends in this market are important for manufacturers and exporters from the region. Therefore, the analysis of the impact of the European Union imports on wood flooring production in the SEEC was conducted by application of econometric modelling. The parameters of the obtained model show that the increase of approximately 0.75 % could be expected in the production of wood flooring in selected South-Eastern European countries for each precentral increase in the European Union imports. In addition to these results, the paper presents the analysis of the competitiveness of wood flooring export from the region measured by the Competitiveness Growth Index (RCA1). The aim of this analysis was to quantify the level of their price and non-price competitiveness in the European Union market. Conducted analyses show that the Competitiveness Growth Index (RCA1) had positive values (higher than one) for most significant countries from the SEEC for most of the observed period. - Odabrane zemlje jugoistočne Europe (SEEC – Albanija, Bosna i Hercegovina, Hrvatska, Crna Gora, Sjeverna Makedonija, Srbija i Slovenija) značajni su proizvođači i izvoznici drvenih podova u Europi. U 2018. godini 9,4 % europske ponude drvenih podova proizvedeno je upravo u toj regiji. Regija je neto izvoznik drvenih podova jer izvozi više od 50 % ukupne proizvodnje. Najvažnije je tržište za izvoz drvenih podova Europska unija, na koju otpada više od 60 % ukupnog izvoza. Trendovi na tržištu Europske unije vrlo su važni za proizvođače i izvoznike iz promatranih zemalja SEEC-a. Stoga je primjenom ekonometrijskog modeliranja analiziran utjecaj uvoza Europske unije na proizvodnju drvenih podova u SEEC regiji. Parametri dobivenog modela pokazuju da se sa svakim postotkom povećanja uvoza u Europsku uniju može očekivati rast proizvodnje drvenih podova u odabranim zemljama jugoistočne Europe za oko 0,75 %. Osim rezultata provedene analize, u radu su izneseni i rezultati analize konkurentnosti izvoza drvenih podova iz zemalja SEEC-a mjereni indeksom rasta konkurentnosti (RCA1). Cilj analize bio je kvantificiranje razine njihove cjenovne i necjenovne konkurentnosti na tržištu Europske unije. Provedene analize pokazuju da je indeks rasta konkurentnosti (RCA1) za najznačajnije zemlje SEEC-a u većini godina promatranog razdoblja imao pozitivne vrijednosti (veće od 1).

Analiza europskog instituta privremene zaštite [Elektronička građa] / Mario Krešić.
Bibliografske bilješke uz tekst ; bibliografija i izvori: 44 jed. - Sažetak ; Summary. - Tri teorijska alata korisna za analizu pravnih instituta jesu: modeli institucija, modeli primjene pravila i modeli odnosa između normativnih sustava. Predmet je analize europski institut privremene zaštite, što je potaknuto sljedećim praktičnim problemom. Propust njegove primjene može ugroziti funkcioniranje država i europskog poretka, izazvati napetosti u međudržavnim odnosima te pripisati nepravednu odgovornost državama. U ovom članku ograničit ćemo se na primjenu prvih dvaju teorijskih alata i pokazati njihovu korisnost za utvrđivanje sljedećih obilježja instituta: vrsta, dio strukture koji se odnosi na pozadinska načela te mogućnosti pravnog usmjeravanja njegove primjene. Polazeći od postavke da je uzrok zanemarivanja instituta njegovo nerazumijevanje, pretpostavit ćemo tri prigovora njegovoj primjeni i analizirati prigovor prema kojem je odluka o primjeni instituta isključivo političko pitanje. - The theoretical tools which are useful for the analysis of legal institutes include models of institutions, models of the application of rules, and models of relations between normative systems. The author analyses the European institute of temporary protection focusing on the related practical problems. Namely, its inadequate application can endanger the functioning of states and the European order, cause tensions in relations between states and attribute unfair responsibility to states. In this study, the author applies the first two theoretical tools and demonstrates their usefulness in determining the following characteristics of institutes: their type, a part of structure related to background principles and possibilities of legal regulation of their application. Starting from the premise that the cause of the neglect of the institute is a lack of its understanding, we will assumd three objections to its application and analyse the objection according to which the decision on the application of the institute is an exclusively political issue.

Važnost prikupljanja sredstava (fundraising) za djelovanje neprofitnih organizacija [Elektronička građa] : primjer globalnog pokreta Mary’s Meals / Miro Radalj. - Graf. prikazi.
Bibliografske bilješke uz tekst. - Sažetak ; Summary. - Prikupljanje sredstava (fundraising) vrlo je važna aktivnost neprofitnih organizacija jer bez financijskih sredstava teško bismo mogli ostvariti svoju misiju. Planiranje prikupljanja sredstava čest je posao djelatnika za odnose s javnošću u neprofitnim organizacijama. Za uspješno prikupljanje sredstava neizostavan je jasno definiran razlog za potporu (case for support). Negativan publicitet povezan s troškovima kampanje može imati učinak na napore organizacija u prikupljanju sredstava jer ona najčešće ovise o potpori javnosti. Uobičajena visina troškova kampanje ne bi smjela prelaziti 12 – 15% ukupno prikupljenih sredstava, a troškovi do 20 % postali su gornja prihvatljiva razina. Prikupljanje sredstava mora poštovati etičke standarde, a troškovi se moraju kontrolirati. Brojne nevladine organizacije upravo su na etičkim standardima izgubile reputaciju, nestale sa scene i nanijele štetu cijelomu neprofitnom i humanitarnom sektoru. Jedan od najupečatljivijih primjera dobra prikupljanja i učinkovita korištenja prikupljenih sredstava međunarodna je humanitarna organizacija Mary’s Meals (Marijini obroci). - Fundraising is a very important activity of non-profit organizations because without financial means it would be difficult for them to realize their mission. Often in non-profit organizations the obligation to plan the fundraising is the work of public relations employees. For successful fundraising, it is essential to have a clearly defined case for support. Negative publicity associated with campaign costs can affect the organizations’ efforts in fundraising, as they most often depend on public support. The usual campaign costs should not exceed 12–15% of the total funds raised, and the costs up to 20% have become the highest acceptable level. Fundraising must be accompanied by commitment to ethical standards and cost control. Numerous non-governmental organizations have lost their reputation precisely on ethical standards, vanished from the scene and inflicted damage on the entire non-profit and humanitarian sector. One of the most striking examples of good fundraising performance and efficient use of the funds collected, is the international humanitarian organization Mary’s Meals.

Before and after enforcement of GDPR [Elektronička građa] : personal data protection requests received by Croatian Personal Data Protection Agency from academic and research institutions / Livia Puljak, Anamarija Mladinić, Ron Iphofen, Zvonimir Koporc. - Graf. prikazi.
Bibliografija: 16 jed. - Summary. - Introduction The European Union’s (EU) General Data Protection Regulation (GDPR) was put in force on 25th May 2018. It is not known how many personal data protection requests the national authority in Croatia had received before and after GDPR, and how many of those were related to research. Materials and methods We obtained data from the Croatian Personal Data Protection Agency (CPDPA) about requests/complaints related to personal data protection that were received specifically from academic/research institutions, specifically the number and type of all cases/requests between the years 2015-2019. Results In 2018, CPDPA had a dramatic increase in the number of requests in the post-GDPR period, compared to the pre-GDPR period of the same year. In 2019, CPDPA received 2718 requests/complaints; less than in the year 2018. From 2015 to 2019, CPDPA received only 37 requests related to research. Conclusions Very few requests about personal data protection from academic and research institutions in Croatia were submitted to the national Croatian data protection authority. Future studies could explore whether researchers have sufficient awareness and knowledge about personal data protection related to research, to adequately implement the GDPR regulations.

The Breivik case and the comparative issues of criminal (in)sanity [Elektronička građa] / Mislav Burazer. - Graf. prikazi.
Bibliografija: str. 36-38. - Summary. - In the summer of 2011, Anders Behring Breivik committed a terrorist attack in Norway in which 77 people were killed, and at least 319 more were injured. This paper analyses several aspects of the deadliest attack on European soil since World War II, primarily the psychological background of this crime and its legal implications. The paper consists of three sections. The first section presents the comparative and legal basics of criminal insanity that is necessary in order to understand the sections that follow. The second section deals with the perpetrator’s psychological profile and the great debate that had ensued due to the contradicting reports of the Norwegian experts. The last section of the paper summarises the essence of the previous two sections while presenting a comparative procedural analysis of hypothetical trials in select jurisdictions. This paper is based on a comparative analysis of legal norms that aims to highlight the high complexity of the issue. The Breivik case has been selected as an ideal example because, on the one hand, it has created a number of contradicting opinions within its domestic legal system while, on the other hand, its universal nature makes it suitable for a more complex comparative analysis.

Delimitation of co-perpetration from aiding and abetting in the criminal offence of robbery [Elektronička građa] / Vedran Mijanić, Lucija Sokanović.
Bibliografija: str. 18-19. - Summary. - Analysis of the case law related to the prosecution of the criminal offense of robbery. Robbery is a complex criminal offense committed when a perpetrator uses force against another person, as well as when they threaten to directly endanger one's life or cause physical injury, or when they seize another's movable property with the aim of misappropriating it. Methods: In selected cases, the application of main theories regarding complicity was examined and critically tested, taking into account the findings of the fact. Results: The analysis of the current case law points to the absence of clear criteria for the delimitation of complicity from aiding and abetting in the criminal offense of robbery. Criminal law theory leaves too much empty space subject to manipulation when, by mentioning substantial contribution, it refers to behaviors without which an offense could not have been committed in the planned manner. The will of the perpetrator should constitute a secondary tool to be used only in controversial, borderline situations, where the nature of the behavior not pertaining to the essence of the criminal offense, due to its character and importance within the joint plan, requires it to be equated with the perpetration act. In that regard, as the joint plan is not a term that can be fully objectified since the importance of roles within the plan can vary from one group of perpetrators to another, assessing the will of the perpetrator can be an alternative to resort to in situations where it is not possible to evaluate the quality of a behavior based on objective rules. Conclusion: Uneven case law in the evaluation of the behavior of individual participants in robbery contributes to the inequality of citizens before the law and endangers legal security – one of the foundations of the rule of law.

Izloženost mladih novim vrstama droga i izazovi prikladne pravne reakcije [Elektronička građa] / Barbara Herceg Pakšić, Ivan Pakšić. - Graf. prikazi.
Bibliografske bilješke uz tekst ; bibliografija i izvori: 30 jed. - Sažetak ; Summary. - Nove psihoaktivne tvari oblik su sintetičkih droga čija je zadaća oponašati učinak klasičnih droga. Najviše su zastupljeni tzv. sintetički kanabinoidi, koji su prisutni i u Republici Hrvatskoj najčešće pod nazivom osvježivači zraka. Donedavno su se mogli pronaći u slobodnoj prodaji s obzirom na to da nisu bili obuhvaćeni relevantnim prohibitivnim odredbama o suzbijanju droga hrvatskog zakonodavstva. Takvo je stanje potrajalo sve do travnja 2019. kad su konačno učinjene nužne zakonske promjene u korist zabrane. S druge strane, na štetno djelovanje novih droga, poglavito na mladu populaciju, učestalo se medijski upozoravalo godinama prije legislativnog zahvata. Znanstvena su istraživanja o toj temi izostala u odnosu na potrebnu razinu. Autori ovoga rada stoga predstavljaju rezultate dvaju istraživanja koja pokazuju izloženost srednjoškolaca na području Osijeka tim drogama. Dobivene spoznaje potvrdile su pretpostavke o dobroj upoznatosti s osvježivačima kao i njihovu relativno visoku konzumaciju. Vezano uz prikazane spoznaje autori jasno (pr)ocjenjuju recentnu legislativnu reakciju kao zakašnjelu. S obzirom na nove okolnosti u tom području rad treba poslužiti i kao poticaj daljnjim istraživanjima te teme. - New psychoactive substances are a form of synthetic drugs produced to mimic the effects of classical drugs. The most represented are the so-called synthetic cannabinoids, present also in the Republic of Croatia (commonly under the name of air fresheners). Until recently, they were commercially available since they were not included in the relevant prohibitive drug suppression provisions of Croatian legislation. This situation lasted until April 2019, when the necessary legal changes in favour of the ban were finally made. On the other hand, the harmful effects of new drugs, especially on the young population, have been covered by media for years before the legislative intervention. There is a lack of scientific research on this topic in relation to the required level. The authors of this paper therefore present the results of two studies showing the exposure of high school students in the Osijek area to these drugs. The obtained findings confirmed the hypotheses about the high familiarity with the refreshers as well as their relatively high consumption. Concerning the findings presented, the authors clearly (re) evaluate the recent legislative reaction as delayed. Given the new circumstances in this field, the paper should also serve as an impetus for further research on this topic.

GETOŠ, Anna-Maria
Kaznenopravno i kriminološko poimanje "delinkventnog" nasilja u Hrvatskoj [Elektronička građa] / Anna-Maria Getoš Kalac, Petra Šprem.
Bibliografske bilješke uz tekst ; bibliografija i mrežni izvori: 25 jed. - Sažetak ; Summary. - Kazneno pravo i kriminologija isprepleću se u svom predmetu i njihov je međuodnos conditio sine qua non svake uspješne politike suzbijanja kažnjivog ponašanja. Ipak, te dvije sestrinske discipline nemaju identičan pogled na određene fenomene, pa ni na ljudsko ponašanje općenito, što je rezultat različite svrhe i cilja kojima se vode pod zajedničkim krovom kaznenih znanosti. Dok će kazneno pravo utvrditi koja će se ponašanja regulirati pravnim normama te u kojem se slučaju povrede pravnih normi trebaju pripisati odgovornosti njihovih počinitelja, a potom za potonje predvidjeti sankciju, kriminologija izučava ponašanja koja su pravnim normama zabranjena i propituje zašto, kako i koliko često do njih dolazi. Fenomen nasilja, kao tradicionalan predmet kriminoloških istraživanja, nesporno je i u fokusu kaznenog prava, no kut gledanja jedne i druge discipline na istu pojavu ipak neće biti isti. Autorice u prvom dijelu rada ispituju antagonizme kaznenog prava i kriminologije u odnosu na fenomen nasilja te na temelju tako dobivenih spoznaja analiziraju smislenost korištenja kaznenopravnim kategorijama za potrebe definiranja i konceptualizacije nasilja kao predmeta kriminološkog istraživanja. Na primjeru fizičkog nasilja autorice upućuju na često nekritičko preuzimanje pravnih termina, instituta i koncepata u kriminološkim istraživanjima, a bez iscrpna uvida u njihovu svrhu i bitno značenje koje imaju u okviru kaznenog prava. U tom smislu dovode u pitanje komplementarnost kaznenopravnih instituta s empirijskim zahtjevima kriminološkog izučavanja nasilja. Drugi dio rada bavi se transpozicijom kaznenopravnih instituta iz općega dijela Kaznenog zakona na „kriminološki jezik“, što je nužan preduvjet za holističko, autentično i racionalno istraživanje nasilja kao društvene pojave, a ne pravne kategorije. - The close relationship between criminal law and criminology is a conditio sine qua non of any successful criminal law policy. However, these two closely related disciplines often have different perspectives on a particular phenomenon, as well as on human behaviour in general. The aforementioned is the result of both disciplines striving to achieve a different purpose within the same field of criminal sciences. On the one hand, criminal law determines which behaviour will be regulated by legal norms, in which case the perpetrator should be found liable for their violations, and provides sanctions for such behaviour. On the other hand, criminology studies delinquent behaviour in an effort to find answers to the questions on why, how and how often delinquent behaviour occurs. There can be no doubt that the phenomenon of violence, which is the traditional subject of criminological research, is the focus of criminal law as well. However, there are considerable differences between the perspectives regarding this phenomenon within those two disciplines. In the first part of the paper, the antagonism between criminal law and criminology with respect to the phenomenon of violence was examined. On the basis of obtained results, the authors analysed whether criminal law categories should be used in order to define and conceptualize violence when it is the subject of criminological research. In terms of physical violence, the authors point to the often uncritical takeover of legal terms, institutes and concepts in criminological research, with a lack of detailed insight into their purpose and their essential meaning within criminal law. In addition, the authors question the complementarity of criminal justice institutes and the empirical requirements for the criminological study of violence.

Pitanje broja žrtava logora Jasenovac u hrvatskoj i srpskoj historiografiji, publicistici i javnosti nakon raspada SFR Jugoslavije [Elektronička građa] : činjenice, kontroverze i manipulacije / Vladimir Geiger. - Graf. prikazi.
Bibliografske bilješke uz tekst ; bibliografija i izvori: str. 566-585. - Sažetak ; Summary. - Najkontroverznije i neriješeno pitanje ljudskih gubitaka Hrvatske, i Jugoslavije, u Drugome svjetskom ratu broj je žrtava logora Jasenovac. Popisi žrtava logora Jasenovac te procjene i izračuni povjesničara i demografa najčešće su znatno različiti i u preširokom rasponu od potpunoga umanjivanja do nemogućih megalomanskih navoda te uvjetovani (dnevno)političkim ozračjem. Napose od vremena raspada SFR Jugoslavije pitanje broja žrtava logora Jasenovac iz jedinoga mogućega jednostranog i „megalomanskog” tumačenja znatno se raslojava. U članku se prikazuju i propituju najvažniji historiografski i publicistički radovi o jasenovačkim žrtvama i njihovi odjeci u javnosti, od pristaša „umanjivanja” do zastupnika „megalomanskih” navoda, kao i malobrojna nastojanja nepristranoga sagledavanja toga pitanja u Hrvatskoj i Srbiji od početka 90-ih godina do sadašnjosti. - The most controversial and unresolved issue of human losses of Croatia and Yugoslavia in World War II is the number of victims of the Jasenovac camp. Lists of victims and estimates and calculations by historians and demographers often diverge widely on this point, ranging from minimisation to impossible megalomaniac claims, and are strongly linked to (daily) politics. Especially after the disintegration of the Socialist Federal Republic of Yugoslavia, the issue of the number of victims of the Jasenovac camp began to be interpreted differently from the until then only permitted one-sided and ‘megalomaniac’ approach. Democratic changes, but also rising nationalist sentiment during the Yugoslav Wars of the 1990s, led to studies on the human losses of Yugoslavia in World War II, and the unavoidable issue of the number and structure of Jasenovac camp victims, having a distinct ideological-propaganda background in Croatian and Serbian historiography, opinion journalism, and public discourse. Serb nationalists vastly inflate the number of Jasenovac camp victims, most of all Serbs, while Croat nationalists strive to minimise this number. The issue of the number and structure of Jasenovac victims is heavily nationally, ideologically, and emotionally charged, which greatly hinders evaluation. Proponents of both left and right worldviews in Croatia and Serbia continue to ignore and belittle any research and facts that do not support their favoured image of the past. Furthermore, they devaluate proven facts and present typical justifications. Inflation or reduction, omission, often coupled with ignorance, stem from personal, national, or political motives. It is noticeable that both Croatian and Serbian media, for the most part, transmit such efforts.

MIŠIĆ Radanović, Nina
Prijepori o kaznenoj odgovornosti medicinskih djelatnika za stručnu pogrešku [Elektronička građa] / Nina Mišić Radanović.
Bibliografske bilješke uz tekst ; bibliografija i izvori: 83 jed. - Sažetak ; Summary. - U pravnim i medicinskim krugovima te među pacijentima i njihovim udrugama kao i u općoj javnosti posljednjih su godina sve prisutnija dva prijepora u vezi s kaznenom odgovornosti liječnika i drugih medicinskih djelatnika za stručnu pogrešku. Prvi prijepor tiče se uopće potrebe za kažnjavanjem u situaciji u kojoj za istu stručnu pogrešku istodobno postoji njihova disciplinska i građanska odgovornost te osiguranje od profesionalne odgovornosti. Drugi prijepor vezan je za postojanje posebnoga kaznenog djela nesavjesnog liječenja koje su zadržale u svom zakonodavstvu sve države nastale raspadom Jugoslavije, dok države zapadnokontinentalnog i angloameričkog pravnog sustava kaznenu odgovornost medicinskih djelatnika vezuju uz opće inkriminacije protiv života i tijela. Stoga autorica prikazuje i analizira dva normativna modela kažnjivosti, stajalište Europskog suda za zaštitu ljudskih prava, argumentaciju za kaznenu odgovornost i protiv kaznene odgovornosti medicinskih djelatnika i za redefiniranje kažnjivosti te predlaže de lege ferenda moguće izmjene zakonodavnog okvira. - Over the past few years, two controversies have been increasingly present in legal and medical circles, as well as among patients, their organizations and the general public, regarding the criminal liability of physicians and other medical personnel for professional errors. The first controversy regards the general need for sanctions in situations where both disciplinary and civil liability exist for the same medical error, as well as professional liability insurance. The other controversy is related to the existence of a special criminal offence of medical error which has been included in the legislation of all the former Yugoslav countries, while in the Western civil law and common law countries criminal liability of medical professionals is included among the general offences against person. Therefore, the author analyses two normative models of culpability, the perspective of the European Court of Human Rights, the argumentation for and against criminal liability of medical professionals, as well as those focusing on redefining culpability, and proposes possible de lege ferenda amendments of the legislative framework.

Sex estimation from handprints in a Croatian population sample [Elektronička građa] : developing a tool for sex identification in criminal investigations / Andrea Kolić, Ivan Jerković, Šimun Anđelinović. - Ilustr., graf. prikazi.
Bibliografija: 25 jed. - Summary. - To test if handprint measurements show sexual dimorphism in the Croatian population, and to develop population-specific sex estimation standards. Methods: A cross-sectional study was conducted on 100 adult volunteers from a Croatian population (50 males and 50 females) aged between 20 and 45 years. Using a fingerprint ink, we collected handprints of both hands on a paper sheet. We scanned handprints and took 13 measurements. Bilateral asymmetry and sexual dimorphism of the measurements was analyzed and sex estimation models were developed using linear discriminant analysis. Results: All measurements exhibited statistically significant sexual dimorphism (P<0.001). Univariate discriminant functions provided sexing accuracy from 75% to 92%. The highest accuracy rate (92%) and the lowest sexing bias (0%) was obtained using the handprint breadth. A multivariate discriminant function could estimate sex with 93% accuracy, but with more pronounced sexing bias (10%). Conclusion: We showed that handprint measurements could be used for sex estimation in the Croatian population with a high accuracy level. Therefore, they could serve as a valuable tool for biological profiling of perpetrators in criminal investigations when other evidence is not conclusive.

Teorijski i praktični aspekti pravosudne suradnje Hrvatske i Bosne i Hercegovine u postupcima izručenja vlastitih državljana [Elektronička građa] / Damir Primorac, Maja Buhovac, Marko Pilić. - Graf. prikazi.
Bibliografske bilješke uz tekst ; bibliografija i izvori: 54 jed. - Sažetak ; Summary. - Institut izručenja najstariji je oblik međunarodne pravne pomoći koji je među državama članicama Europske unije zamijenjen europskim uhidbenim nalogom. U odnosu na treće države kakva je Bosna i Hercegovina izručenje je jedini instrument kojim se omogućava transfer osoba koje se trebaju izručiti zbog vođenja kaznenog postupka, ili izvršenja kazne zatvora, ili zbog druge mjere koja podrazumijeva oduzimanje slobode u državi moliteljici. Radi stalna nastojanja da se osiguraju pravna sigurnost, načelo zakonitosti i vladavina prava, države kao subjekti međunarodnog prava svoje odnose na području ekstradicijskog prava sve više reguliraju potpisivanjem bilateralnih sporazuma kojima žele ostvariti taj cilj. U tom smjeru Hrvatska i Bosna i Hercegovina zaključile su 28. studenog 2012. Ugovor o izručenju koji se s tim datumom počeo privremeno primjenjivati, a stupio je na snagu 6. ožujka 2014. Ugovorom su, između ostalog, ekstenzivnije uređene odredbe o izručenju vlastitih državljana, čime se na određen način odstupilo od tradicionalnog načela neizručenja vlastitih državljana. Autori u radu analiziraju odredbe Ugovora o izručenju s posebnim osvrtom na odredbe o izručenju vlastitih državljana, osobito državljana koji imaju dvojno državljanstvo, što je nerijetko slučaj državljana Hrvatske i Bosne i Hercegovine. Mnoge države u Europi i svijetu tradicionalno se snažno protive izručenju vlastitih državljana. Načelo neizručenja vlastitih državljana proizlazi iz suverenosti država i njezinih državljana te obveza koje ih vežu, a osobito nepovjerenja u pravosudne sustave drugih država. Međutim, imajući u vidu da je temeljni cilj izručenja borba protiv nekažnjavanja osoba za koje se sumnja da su počinile kazneno djelo ili koje su osuđene za to, tada bi se nepovjerenje kao razlog neizručenja vlastitih državljana trebalo uzeti s velikim oprezom. - The institute of extradition is the oldest form of international legal assistance which has been replaced by the European arrest warrant in Member States of the European Union. Regarding the third countries, such as Bosnia and Herzegovina, extradition is the only instrument enabling the transfer of persons that have to be extradited for criminal trial, imprisonment, or any other measure of deprivation of freedom in the applicant state. In an effort to ensure legal certainty, the principle of legality and the rule of law, states as subjects of international law increasingly regulate their relations in the field of extradition law by signing bilateral agreements in order to achieve that aim. Within this framework, Croatia and Bosnia and Herzegovina concluded the Treaty on Extradition on 28 November 2012. The Treaty was applied temporarily starting from the above date, and it came into force on 6 March 2014. The Treaty regulates the extradition of citizens, departing from the traditional principle of non-extradition of a state’s own citizens. The authors analyse the Treaty on Extradition with a special focus on extradition of a country’s own citizens, especially those with dual citizenship, which is often the case with citizens of Croatia and Bosnia and Herzegovina. Many European and world countries strongly oppose the extradition of their own citizens. The principle of non-extradition of a country’s own citizens is based on the concept of the sovereignty of states and their citizens and their mutual obligations, and it is often a consequence of distrust of judicial systems of other states. However, bearing in mind that the fundamental aim of extradition is the struggle against the absence of punishment for persons suspected or convicted of criminal offences, distrust as a reason for non-extradition should be taken with the greatest caution.

Prijenos vlasništva fiduciae causa i causa donationis [Elektronička građa] / Tomislav Karlović.
Bibliografske bilješke uz tekst ; bibliografija: 45 jed. - Sažetak ; Summary. - U radu se obrađuje problem obuhvata i značenja prijenosa (fidi) fiduciae causa s obzirom na tekstove prema kojima je došlo do fiducijarnog prijenosa vlasništva s uključenom, kao međufazom ili konačnom fazom, svrhom darovanja. Analizirani su fragmenti iz Digesta za koje se u romanistici smatra da su se izvorno odnosili na fiduciju. Obrađeni su njihov sadržaj, način na koji je u njima izražena fiducijarna obveza te odnos te obveze i prava na tužbu koje je iz nje izviralo prema konačnoj svrsi prijenosa. Izdvojen je i raščlambi podvrgnut tekst D. 39, 5, 18 pr.-2 kao primjer negotium mixtum cum donatione, u kojem je posebno vidljiv odnos fiducijarne kauze i causae donationis. Na kraju je iznesen zaključak o položaju causae fiduciae prema drugim pravnim osnovama. - The author elaborates the issue of the scope and significance of the transfer made (fidi) fiduciae causa in Roman law, taking into consideration sources related to the included purpose of the transfer – causa donationis. The analysis focuses on the texts from the Justinian’s Digest that originally dealt with the fiducia in which either the final or intermediary stage in the fulfilment of fiduciary’s obligation was accomplished for the purpose of donation. The study analyses their contents and the manner in which the effects of causa fiduciae, most importantly the right of action, were exclusive towards other causes, viz. causa donationis. Special attention is paid to Ulpian’s text D. 39, 5, 18 pr.-2, as an example of negotium mixtum cum donatione, in which the development of the relationship between fiducia and causa donationis may be discerned. In conclusion, final remarks are given on the role and place of causa fiduciae.

"Radim sve što treba." [Elektronička građa] : Aktivisti u mjesnim zajednicama u Jugoslaviji 1970-ih i 1980-ih / Igor Duda.
Bibliografske bilješke uz tekst ; bibliografija i izvori: str. 756-757. - Sažetak ; Summary. - Uvođenje mjesnih zajednica kao samoupravnih jedinica unutar općine bilo je oblik jačanja društvenoga samoupravljanja i socijalističke izravne demokracije u Jugoslaviji te, prema marksističkoj teoriji, dio procesa odumiranja države. Začetke donosi Ustav iz 1963., no tek Ustavom iz 1974. mjesne su zajednice postale obavezan oblik samoupravnoga organiziranja građana. Zamišljene kao svojevrsne proširene obitelji, umnogome su ovisile o inicijativi odozdo i djelovanju aktivista. Rad donosi teorijske pretpostavke i praktične aspekte aktivističkoga djelovanja u mjesnim zajednicama u raznim dijelovima Jugoslavije, a na temelju analize uspostavljaju se karakteristični tipovi aktivista koji su određeni generacijskim, klasnim i interesnim odnosima. Podaci se ponajviše crpe iz onodobne literature, specijaliziranoga lista Mjesna zajednica i arhivskoga gradiva. - After the experience with people’s committees, small municipalities, and residential communities, socialist Yugoslavia began introducing local communities as self-governing units and communities of citizens within the new, larger municipalities. They were a way of strengthening social self-management and socialist direct democracy and, according to Marxist theory, envisioned as part of the withering away of the state, and therefore part of the process of de-bureaucratisation and humanisation of social relations. The foundations of the new socio-political organisation were set down by the 1963 Constitution, but it was only the 1974 Constitution that established local communities as one of the core parts of the socio-political system and a compulsory form of citizens’ self-government organisation. Envisioned as something akin to extended families, they were greatly dependent on initiatives from below, on the energy, enthusiasm, and free time of interested citizens. Therefore, this paper attempts to answer the following questions: how was the concept of local communities envisioned; did citizens’ interest reach the expected level, and who were the activists among them; what prompted their enthusiasm, and how did they understand their activities? Based on our analysis, we establish the characteristic types of activists determined by generational, class, and interest relations. In defining the theoretical and practical aspects of social self-government in local communities, the paper refers to the Programme of the League of Communists of Yugoslavia, constitutional and legal provisions, and the theoretical tenets of the actors of that period. Our approach also considers the then and current papers from the field of administrative sciences.

Odnos zagrebačke gradske vlasti prema južnoj periferiji između dva svjetska rata [Elektronička građa] / Hrvoje Čapo. - Graf. prikazi.
Bibliografske bilješke uz tekst ; bibliografija i izvori: str. 76-78. - Sažetak ; Summary. - Snažno useljavanje iz ruralnih krajeva nakon Prvoga svjetskog rata te kronični nedostatak stanova uzrokovali su naseljavanje južne periferije Zagreba. Taj je prostor zbog smještaja između željezničke pruge na sjeveru i neregulirane rijeke Save na jugu u promatranom razdoblju i dalje bio izoliran. Do vremena kada je Gradsko poglavarstvo primijetilo probleme vezane za naseljavanje na urbanistički neuređenom području doseljenici su već bili dosegnuli kritičnu masu da bi kao udruge građana dobili snagu za ostvarivanje svojih ciljeva u gradskom načelstvu. U radu će se nastojati opisati najvažniji trenuci u oblikovanju južne periferije između dva svjetska rata s posebnim naglaskom na utjecaj uređenja rijeke Save i suodnos gradskih političkih elita i novih stanovnika.

Poslušnik karađorđevićevskoga režima Franjo Urbany [Elektronička građa] / Mario Stipančević. - Ilustr.
Bibliografske bilješke uz tekst ; bibliografija: str. 624-627. - Sažetak ; Summary. - Preustroj zagrebačkoga redarstva i njegovo stavljanje pod izravni nadzor beogradskih centara moći za nove je vlastodršce, čini se, bio jedan od važnijih ciljeva nakon uspostave Kraljevstva Srba, Hrvata i Slovenaca. Pogodnim za provođenje preustroja prepoznat je i odabran prijeratni zagrebački upravno-policijski službenik Franjo Urbany. U prilogu se raspravlja o njegovu profesionalnom i privatnom životu, s posebnim osvrtom na ključne događaje koji su ga obilježili. To se osobito odnosi na Urbanyjeve svjetonazorsko-ideološke mijene poput sudjelovanja u spaljivanju mađarske zastave 1895. te progona negdanjega sudruga iz toga pothvata Stjepana Radića nedugo nakon uspostave nove državne zajednice. Posebna je pozornost posvećena i ulozi Urbanyja u reorganizaciji zagrebačke policije te razlozima napuštanja mjesta ravnatelja Kraljevskoga redarstvenog ravnateljstva. - Like his numerous contemporaries from the period of the dissolution of Austria-Hungary and establishment of the new Yugoslav state, Franjo Urbany (1874–1951), a lawyer from Zagreb, General Attorney and police chief of the second-largest city in the Kingdom of Serbs, Croats and Slovenes, had to make a considerable political and ideological U-turn in order to continue his presence in high administrative circles. It would be hard to say whether his personal pre-war views were in opposition to the new situation or not, but there can be little doubt that he wanted to ingratiate himself to the new power-holders. This was a necessity if he were to continue climbing the administrative ladder in the new environment. The difficulty was that Urbany, like many of his kind from the occupying system, had to virtually jump into the lap of those who had been occupied up until that point and – in the new circumstances – were the leading political forces of the state union of which Croatia had suddenly become a member. There can be little doubt that Urbany knew how to adapt. Once a participant in the burning of a Hungarian tricolour at Zagreb’s Jelačić Square in 1895 and a minor administrator of the Austro-Hungarian occupying forces in Serbia during World War I, he became a persecutor of the Croatian opposition and a campaigner for the protection of the centralistic and unitarian Yugoslavian community ruled by the Karađorđević dynasty. These merits provided him with the opportunity to lead and restructure the Zagreb police in the period of 1921–1924. Despite his successes, it appears that the power-holders were in search of a firmer hand for the upcoming times, in order to combat the increasing numbers of dissenters. Because of this, Urbany was forced to resign as the chief of Zagreb’s police and was succeeded by the notorious Janko Bedeković.

Stranputice Joje Vragovića [Elektronička građa] : ulomci biografije jednoga zagrebačkog policajca / Mario Stipančević. - Ilustr.
Bibliografske bilješke uz tekst ; bibliografija: str. 126-129. - Sažetak ; Summary. - Rad na temelju dostupnih arhivskih vrela i literature nastoji približiti neke sastavnice životopisa redarstvenika Josipa Vragovića, upravitelja zagrebačke policije u vrijeme monarhističke Jugoslavije i Nezavisne Države Hrvatske. Usporedno se u članku spominje i ustroj međuratnoga zagrebačkog redarstva, a doneseni su i podaci o Vragovićevim najbližim suradnicima iz toga razdoblja. Na kraju se nastojala analizirati i Vragovićeva, s obzirom na istaknute dužnosti koje je obavljao u Nezavisnoj Državi Hrvatskoj, pomalo iznenađujuća sudbina u socijalističkoj Jugoslaviji. - The paper endeavours to outline biographical fragments and fathom the character of Josip Vragović (1886–1965), a long-time employee and director of the Zagreb police in the Kingdom of Yugoslavia and Independent State of Croatia. The paper also shows the structure of the interwar Zagreb police and Vragović’s closest associates. Particular emphasis is put on Vragović’s professional activity in the period of turbulent social and political conditions in 1918, 1941, and 1945, and some light is shed on his private life (as much as possible through available archival sources).

Politička i vojna situacija i oružane snage Kraljevine Srba, Hrvata i Slovenaca / Jugoslavije u informacijama, izvještajima i analizama II. odjela Glavnoga stožera / Generalštaba Vojske Republike Poljske [Elektronička građa] / Andrzej Krzak.
Bibliografske bilješke uz tekst ; bibliografija: str. 190-191. - Sažetak ; Summary. - Kraljevina Srba, Hrvata i Slovenaca / Jugoslavija nije bila glavni predmet operativnih aktivnosti poljskih vojnih obavještajnih službi. Ipak, zbog provođenih i planiranih strateških projekata vezanih za državnu obranu postavljeni su zadaci pribavljanja podataka prije svega o vojnom potencijalu zemlje, njezinoj politici prema susjednim državama i mogućnosti prodaje poljskoga naoružanja. Za rukovodstvo poljske države, kao i za obavještajne časnike, tajno širenje jugoslavenske vojske i politički i vojni odnosi s Čehoslovačkom i Rumunjskom u okviru savezničkih obveza u Maloj Antanti nesumnjivo su bili zanimljivi. Analizirani dokumenti pokazuju da se Jugoslavija poljskoj vojsci činila državom sa složenom unutarnjom situacijom koja nastoji održati versailleski poredak i ima brojne znanstvene i kulturne veze s Poljskom. S druge strane zapaženo je da Kraljevina simpatizira Rusiju, Češku i Njemačku, kao i brojnu bjelogardijsku dijasporau, za koju se smatralo da su se u nju infiltrirali boljševici, što je zasigurno utjecalo na odluke o potrebi njezina uključivanja u obavještajni opseg II. odjela te političkih i vojnih procjena Kraljevine Jugoslavije i njezinih oružanih snaga. - The Kingdom of Serbs, Croats and Slovenes / Yugoslavia was not a major subject of the operational activities (main operational objective) of the Polish military intelligence. Nonetheless, due to the implemented and planned strategic projects related to national defence, assignments were made to collect data, primarily on the military potential of the country, its politics towards neighbouring states, and the possibility of selling Polish arms to it. There is no doubt that the leadership of Poland and the intelligence officers were interested in the secret expansion of the Yugoslav army and its political and military relations with Czechoslovakia and Romania within the frame of its obligations as part of the Little Entente. The analysed documents show that the Polish army saw Yugoslavia as a state with complicated internal relations that seeks to preserve the Versailles order and has numerous scholarly and cultural ties with Poland. On the other hand, they detected Yugoslavia’s sympathy for Russia, Czechoslovakia, and Germany as well as its numerous White Guard diaspora, which was seen as an element infiltrated there by the Bolsheviks, and this certainly also influenced the decision that the Kingdom of Yugoslavia should be included in the intelligence activities of the Management of Intelligence and Reconnaissance Intelligence (P2) in order to evaluate its politics and military capabilities.

Economic violence against women in Croatia [Elektronička građa] : a comparative study between continental and maritime county / Ivan Miškulin. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - Economic violence (EV) refers to acts of control and monitoring of the behavior of an individual in terms of the use and distribution of money, and the constant threat of denying economic resources. EV has hindered a great proportion of women from achieving economic autonomy and sustainable livelihood for themselves and their dependents. The aim of this study was to examine the prevalence of EV among Croatian women, to identify the main forms of EV and to evaluate interconnection between EV and selected sociodemographic indicators. As part of this cross-sectional study a validated, anonymous questionnaire that contained questions regarding sociodemographic data as well as questions regarding EV was self-administered to a sample of women from two Croatian counties, one continental (Osijek-Baranja) and one maritime (Istria), during April and May 2017. The study sample included 1314 women, the median age being 41 (interquartile range 32–55) years. The overall prevalence of EV was 18.9%; 77.5% being qualified as less and 22.5% as more severe. Among the women who experienced EV 96.0%, 59.8% and 36.1% of them were exposed to economic control, economic exploitation and employment sabotage, respectively. The EV was more prevalent among women from maritime (Istria) county (P<0.001); women aged between 44 and 56 years and women aged between 31 and 43 years (P<0.001); women who were single (P<0.001); women with lower educational level (P=0.006) and women with under average self perceived socioeconomic status (P<0.001). It can be concluded that EV is highly prevalent among Croatian women and as such represents an important public health challenge within this population. Selected sociodemographic indicators represent significant risk factors for the development of EV in the studied population. - Ekonomsko nasilje (EN) odnosi se na djela kontrole i praćenja ponašanja pojedinca u smislu upotrebe i raspodjele novca i stalne prijetnje uskraćivanjem ekonomskih resursa. EN je spriječilo veliki broj žena u postizanju ekonomske autonomije i održivog života za sebe i svoje uzdržavane članove obitelji. Cilj ovog istraživanja bio je ispitati prevalenciju EN među ženama u Hrvatskoj, identificirati glavne oblike EN i procijeniti međusobnu povezanost EN i odabranih sociodemografskih pokazatelja. Kao dio ove presječne studije, validirani, anonimni upitnik koji je sadržavao pitanja u vezi sa sociodemografskim podacima, kao i pitanja u vezi s EN-em, je samostalno ispunjavao uzorak žena iz dvije hrvatske županije, jedne kontinentalne (Osječko-baranjske) i jedne priobalne (Istarske), tijekom travnja i svibnja 2017. godine. Uzorak ispitanica obuhvaćao je 1314 žena, srednje dob od 41 (interkvartilni raspon 32-55) godine. Ukupna prevalencija EN bila je 18,9%; 77,5% je kvalificirano kao lakši, a 22,5% kao teži oblik EN. Među ženama koje su doživjele EN 96,0%, 59,8% i 36,1% njih bilo je izloženo ekonomskoj kontroli, odnosno ekonomskom iskorištavanju i sabotaži u zapošljavanju. EN je bilo zastupljenije među ženama iz priobalne županije (Istra) (P<0,001); među ženama u dobi između 44 i 56 godina i ženama u dobi između 31 i 43 godine (P<0,001); među ženama koje nisu bile u vezi (P<0,001); ženama s nižom razinom obrazovanja (P=0,006) i ženama s ispodprosječnim samoprocijenjenim socioekonomskim statusom (P<0,001). Može se zaključiti da je EN vrlo rasprostranjeno među ženama u Hrvatskoj i kao takvo predstavlja važan javnozdravstveni izazov u ovoj populaciji. Odabrani sociodemografski pokazatelji predstavljaju značajne čimbenike rizika za razvoj EN u istraživanoj populaciji.

Elektroničko nasilje među djecom i mladima [Elektronička građa] : pregled preventivnih programa / Vjekoslav Jeleč, Gordana Buljan Flander, Ana Raguž, Krešimir Prijatelj, Dora Vranjican.
Bibliografija: str. 472-481. - Sažetak ; Summary. - U posljednjem se desetljeću sve veći broj istraživanja bavi posljedicama elektroničkog nasilja po mentalno zdravlje djece i mladih, a rezultati sustavno pokazuju da je elektroničko nasilje u porastu te da su posljedice po mentalno zdravlje negativne kako za žrtve, tako i za počinitelje. U svijetu, Europi i Hrvatskoj nastoje se razviti i evaluirati učinkoviti programi preventivnih aktivnosti elektroničkog nasilja usmjereni na djecu, mlade, stručnjake, roditelje i sve one koji sudjeluju u odgoju i obrazovanju djece. Zajednička su obilježja provođenja uspješnih preventivnih programa oko kojih se većina autora slaže edukacija učenika, nastavnika, stručnih suradnika i roditelja, njihova suradnja, korištenje kvalitetnih interaktivnih edukativnih sadržaja te znanja o postupanju po protokolu u slučajevima elektroničkog nasilja. - In the last decade, a growing body of research has dealt with the effects of cyberbullying on mental health of children and youth, and the results have systematically shown that cyberbullying is on the rise and that the mental health consequences are negative for both victims and perpetrators. Effective prevention programs for cyberbullying targeting children, youth, professionals, parents, and all those involved in upbringing are being developed and evaluated in the world, Europe and Croatia. Common features of implementing successful prevention programs that most authors agree on are the education of students, teachers, professional assistants and parents, their collaboration, the use of quality interactive educational content and knowledge of following protocols for schools in cases of electronic violence.

Obiteljski domovi kao rastući vid obiteljskog poduzetništva i otvaranja novih radnih mjesta [Elektronička građa] / Narcisa Manojlović. - Graf. prikazi.
Bibliografija: 20 jed. - Sažetak ; Summary. - U Republici Hrvatskoj su se 2003. godine otvorile zakonske mogućnosti za pružanje socijalne usluge smještaja za starije i teško bolesne osobe (do 20 korisnika) u obiteljskim domovima. Taj novi vid obiteljskog poduzetništva u djelatnosti socijalne skrbi, koji ranije nije postojao, od tada do danas kontinuirano bilježi rast ponude i potražnje. Anketnim istraživanjem na ukupnoj populaciji predstavnika obiteljskih domova u Hrvatskoj, sukcesivno u 2017., 2018. i 2019. godini, utvrđen je broj i teritorijalna rasprostranjenost aktivnih obiteljskih domova, kapaciteti i broj korisnika, raspon cijena, minimalni ukupni prihodi te broj i profili radnika koje zapošljavaju, uključujući angažirane članove obitelji i vanjske zaposlenike. Zahvaljujući nesaturiranoj i trajno rastućoj potražnji za uslugom smještaja, pokazalo se da je ponuda obiteljskih domova za starije i teško bolesne osobe prisutna u svim županijama te da je do 2019. godine narasla na 400 aktivnih obiteljskih domova i blizu 6.000 korisnika, s perspektivom daljnjeg rasta. Ustanovljeno je da je prosječno u obiteljskom domu angažirano preko 6 osoba, u okvirnom omjeru: 2 člana obitelji i 4 vanjska zaposlenika. Budući da obiteljski domovi u dobroj mjeri angažiraju „neiskorištene“ materijalne i ljudske resurse kojima obitelj raspolaže (nezaposlene članove obitelji, postojeće objekte i opremu, u slučaju seljačkih domaćinstava i poljoprivredne resurse), cijena novootvorenog radnog mjesta je po prirodi stvari relativno niska. To ovu poduzetničku djelatnost čini još značajnijom, osobito jer se razvija i u manje razvijenim područjima i zapošljava i osobe niže zapošljivosti (nižeg obrazovnog statusa, starije, žene). Može se zaključiti da su obiteljski domovi nimalo zanemariv čimbenik otvaranja novih radnih mjesta i zapošljavanja, sada i ubuduće. - As from 2003, in the Republic of Croatia there are legal possibilities for the provision of social accommodation services for the elderly and seriously ill persons (for up to 20 beneficiaries) in family homes. This has enabled a completely new form of family entrepreneurship in the field of social welfare, which did not exist before, where the growth of supply and demand has been continuously recorded since then. The survey research, which included the total population of active family homes in the Republic of Croatia, successively in 2017, 2018 and 2019, has established their number and territorial distribution, capacity and number of users, price range, calculation of minimum total income, as well as the number and profiles of their employees, including engaged family members and external employees. Thanks to unsaturated and evergrowing demand for accommodation services, it turned out that the offer for family homes for elderly and seriously ill persons was present in all counties and by 2019 was increased to 400 active family homes and close to 6,000 users, with the prospect of further growth. It was found that, on average, more than 6 people were employed in a family home, in an approximate ratio of 2 family members to 4 external employees. Since family homes to a good extent engage the “unused” material and human resources that families have at their disposal (unemployed family members, existing facilities and equipment, and in rural households agricultural resources), the cost of a newly created job is relatively low. That makes this entrepreneurial activity even more important, especially because it is being developed in less developed areas, and is also an opportunity for people of lower employability (older people, people with lower educational status, women). It can be concluded that family homes are not a negligible factor in employment, now and in the future.

Samoprocjena zdravstvenog statusa i nekih aspekata kvalitete života starijih osoba s osteoartritisom koljena [Elektronička građa] / Sandra Rusac Kukić, Silvia Rusac, Marko Buljevac. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Sažetak ; Summary. - Osteoartritis koljena predstavlja važan čimbenik u nastanku tjelesnog oštećenja kod starijih osoba i utječe na funkcionalne sposobnosti osobe, a time i na kvalitetu života. Cilj ovog istraživanja bio je utvrditi postoje li statistički značajne razlike u samoprocjeni zdravlja i nekim aspektima kvalitete života starijih osoba s OA-om koljena. Istraživanje je provedeno na uzorku od 74 ispitanika starijih od 65 godina. U analizi su primijenjeni validirani instrumenti: upitnik WOMAC i upitnik SF-36. Rezultati istraživanja ukazuju kako je najviša povezanost između ukupnog intenziteta pojavnosti simptoma OA-a s tjelesnim bolovima i ograničenjima u ostvarenju životnih uloga zbog tjelesnog zdravlja. Također, utvrđeno je da se ispitanici statistički značajno razlikuju u procjenama jedino prema dobi i trajanju boli, dok nisu utvrđene statistički značajne razlike prema spolu i bračnom statusu. Stoga se može zaključiti kako OA koljena utječe na samoprocjenu zdravstvenog statusa osobe i na kvalitetu života pojedinca. - Knee osteoarthritis can results in physical disability, especially when the person is older. It affects the person´s functional abilities and quality of life. The aim of this paper is to determine if there are statistically significant differences in the self- assessment of health and some aspects of quality of life of older persons with knee OA. The sample included 74 participants aged 65 years and older. WOMAC Questionnaire and SF-36 questionnaire were used for data analysis. The findings show that the highest correlation is between the overall intensity of OA symptoms with pain and inability to achieve a certain life role because of physical pain. The results show that there are statistically significant differences between age and duration of pain, while there is no statistically significant differences between gender and marital status. Knee OA has a great impact on self-evaluation of health status and some aspects of quality of life of older people.

Sociološki osvrt na odrednice studentskoga internetskog kupovanja u Hrvatskoj [Elektronička građa] / Ivana Brstilo Lovrić. - Graf. prikazi.
Bibliografija: str. 55-58. - Sažetak ; Summary. - Valorizirajući internetsko kupovanje kao aktualan fenomen koji je zadnjih godina u globalnom porastu, ovim radom se ukazuje na deficit društvenih, napose socioloških, analiza na temu u kontekstu hrvatskog društva. Pregledom literature o profilima internetskih kupaca postavljen je okvir za ispitivanje studentske populacije koja je prepoznata kao predvodnik suvremenih potrošačkih i tehnoloških trendova. Operacionalizacijom viševrsnih forma kapitala uz varijable demografije, tehnoloških resursa i praksi, ispitane su odrednice studentskoga internetskog kupovanja u Hrvatskoj (N= 1094). Izvorni empirijski nalazi prikupljeni metodom ankete pokazuju da studentsko internetsko kupovanje najpouzdanije predviđaju posjedovani tehnološki resursi, tehnološke vještine i interesi na način da su ispitanici opremljeniji novim tehnologijama s izraženijim tehnološkim vještinama i interesom za praćenjem tehnoloških trendova vjerojatniji internetski kupci. Aspekti tehnoloških resursa i praksi udruženi s ekonomskim kapitalom utvrđeni su značajnima i kod razlikovanja studenata koji (ne)kupuju putem interneta, što je podcrtalo višerazinske nejednakosti u perspektivi studentskog internetskog kupovanja. Izražena zabrinutost oko online rizika te tradicionalna (ne)vezanost za fizičku kupovinu ispostavili su se glavnim razlozima neprakticiranja internetskog kupovanja iz perspektive ispitanika, što je razvojnu dinamiku same prakse zaokružilo temama društvene nejednakosti i nepovjerenja. - Valorising Internet purchase as a current phenomenon that has recently been rapidly growing worldwide, this paper points to the lack of social, especially sociological, analysis of the topic in the context of Croatian society. By reviewing the literature about Internet buyers’ profiles, a research framework has been developed for conducting a survey among students, who are recognised as the anticipators of contemporary consumer and technological trends. Using operationalised multiple forms of capital with demographic variables and variables of technological resources and practices, the analysis of the determinants of Internet purchase among students in Croatia (N = 1094) has been conducted. Original empirical survey findings showed that students’ Internet purchase is predicted most reliably by their technological resources, technological skills and interest in such a way that students better equipped with new technologies, with pronounced technological skills and an interest in following technological trends are more likely to be Internet consumers. The aspects of technological resources and practices combined with economic capital have been affirmed as significant factors in distinguishing students who are (not) buying via the Internet, which underlined multilevel inequalities within the perspective of students’ Internet purchase. A prominent concern about online risks and traditional attachment to physical consumption turned out to be the respondents’ main reasons not to buy via the Internet, which encompassed its developmental dynamics within the topics of social inequality and distrust.

"Obrazovanje za proturječnost i otpor" [Elektronička građa] : prilog rekonstrukciji Adornove "pedagogije" / Predrag Krstić.
Bibliografske bilješke uz tekst ; bibliografija: str. 29-33. - Sažetak ; Summary. - Rad nastoji integrirati zapažanja Theodora W. Adorna o odgoju i obrazovanju, koja su rasuta gotovo po čitavome njegovom opusu. Namjera međutim nije doktrinarna: izdala bi se lojalnost autoru i podbacilo ispod njegove kritike kada bi takva integracija nastojala rekonstruirati neku neokupljenu ili neizrečenu Adornovu "prosvjetnu doktrinu". Kod zakletog antisistematičara ni vizije prosvjetne teorije i prakse ne smiju prerasti u sistem. Riječ je prije o stavu ili držanju koje insistira na pokušaju da se antinomija obrazovanja – neslobodnim sredstvima do cilja slobode, manipulacijom do nemogućnosti da se bude izmanipuliran – unese u školske, i ne samo školske, zadatke, kao cilj koji će onemogućiti ponavljanje Auschwitza, omogućiti autonomiju i osposobiti za autorefleksiju. - The paper seeks to integrate Theodor W. Adorno’s observations about upbringing and education, scattered throughout his almost entire opus. The intention, however, is not doctrinal: loyalty to the author would be betrayed and it would fall short of his criticism if such integration would sought to reconstruct some uncollected or unspoken Adorno’s “educational doctrine”. With a sworn antisystematist, even visions of educational theory and practice must not grow into a system. It is rather about an attitude that insists on trying to bring the antinomy of education – by non-free means to the goal of freedom, by manipulation to the point of impossibility to be manipulated – into school and not only school tasks, as a goal that will prevent Auschwitz’s repetition, enable autonomy and empower for self-reflection.

Akcijski planovi protiv nepismenosti u Hrvatskoj od 1945. do 1970-ih [Elektronička građa] / Tomislav Anić, Vjera Brković. - Graf. prikazi.
Bibliografske bilješke uz tekst ; bibliografija i izvori: str. 727-728. - Sažetak ; Summary. - U kontekstu političkih, gospodarskih i društvenih promjena sredinom XX. stoljeća sustavno se ostvaruju temeljni ciljevi Komunističke partije Jugoslavije na svim razinama te dolazi do strukturnih promjena u društvu. Zadane promjene može se pratiti i preko mjera poduzetih za smanjenje broja nepismenih, što je izravno proizlazilo iz potrebe rješavanja temeljnih društvenih i gospodarskih problema. U radu se problematizira borba protiv nepismenosti u Hrvatskoj nakon Drugoga svjetskog rata. Akcijski planovi opismenjavanja stanovništva koje su sustavno provodili državni organi pokazuju da se korjenito mijenjala slika društva. Odgojno-obrazovne teme i povijest školstva XX. stoljeća u hrvatskoj historiografiji, uz određene iznimke, neistražene su kao primjerice u historiografiji XIX. stoljeća. Autori su analizom izvora i literature uspostavili tri faze odgojno-obrazovnih promjena. U ovom će se radu pratiti problem rješavanja nepismenosti preko promjena odgojno-obrazovnoga sustava i akcijskih planova opismenjavanja od 1945. do završne faze 1974., kada je donesena odluka o osnivanju Komisije za borbu protiv nepismenosti. Namjera je ovim radom doprinijeti istraživanju povijesti obrazovanja u hrvatskoj historiografiji. - In the context of the political, economic, and social changes in the mid-20th century, a systematic implementation of the core goals of the Communist Party of Yugoslavia/ League of Communists of Yugoslavia was conducted on all levels, resulting in structural changes in society. Among other things, these changes were the result of the measures implemented in order to reduce the number of illiterates, and this was directly related to the need to resolve basic social and economic problems. In this paper, the authors examine the struggle against illiteracy in Croatia after World War II. The literacy action plans that were systematically conducted by state authorities indicate that the image of society underwent profound changes. Thus, from a bottom-up perspective, society became subject to long-lasting changes. With certain exceptions, educational topics and the history of education in the 20th century remain unresearched in Croatian historiography, especially when compared to, say, the same topics in the 19th century. Therefore, this topic represents a new beginning in research and, due to its nature, also enters the frame of social history in the second half of the 20th century. Through source and literature analysis, the authors have determined three phases of educational changes. This paper shall examine the problem of combating illiteracy through changes in the educational system and literacy action plans in the period from 1945 to 1974, when the decision to form the Commission for Combatting Illiteracy was made. The aim of this paper and this approach to the topic and problem of illiteracy through literacy action plans is to contribute to history of education research in Croatian historiography.

Aspekti kolaborativne kreativnosti u nastavi glazbe u osnovnoj školi [Elektronička građa] / Jelena Martinović-Bogojević. - Graf. prikazi.
Bilješke uz tekst. - Bibliografija: str. 145-147. - Sažetak ; Summary. - Socio-kulturološka dimenzija kreativnosti nezaobilazni je aspekt u teorijskim razmatranjima fenomena glazbene kreativnosti. Empirijska istraživanja i iskustva iz prakse dovela su do potrebe za rekonceptualizacijom i reinterpretacijom pojma glazbene kreativnosti u obrazovanju. Upravo se kroz socio-kulturološki kontekst razvio i pojam ‘kolaborativna kreativnost’ (eng. collaborative creativity). U školskoj praksi kolaborativna se kreativnost može ostvariti među učenicima, ali i među nastavnicima koji surađuju kroz realiziranje integrativne nastave, izvannastavnih aktivnosti i projektne nastave. U ovom radu predstavit će se neki oblici poticanja kolaborativne glazbene kreativnosti, s posebnim osvrtom na iskustvo učenika i utjecaj koji su zajednički stvaralački procesi imali na njihovu socijalizaciju, motivaciju, ali i na praktičnu primjenu usvojenih znanja. Za metodološki okvir iskorišteno je akcijsko istraživanje provedeno u jednom odjeljenju petog razreda osnovne škole tijekom školske godine 2017./2018. Cilj rada je otvoriti pitanja o mogućnostima poticanja kolaborativne kreativnosti u redovitoj nastavi glazbe, ali i ukazati na objektivne poteškoće za realizaciju ovog oblika kreativnog procesa u školskim uvjetima. - The socio-cultural dimension of creativity is an essential aspect of theoretical examinations of the phenomenon of musical creativity. Empirical research and practical experience have resulted in the need to reconceptualise and reinterpret the concept of musical creativity in education. The concept of collaborative creativity developed through the socio-cultural context itself. In school practice, collaborative creativity can be achieved among pupils, as well as among teachers who cooperate through integrative teaching, extracurricular activities, and project teaching. This paper will present some ways in which to encourage collaborative musical creativity, with a special view to student experiences and the influence that collaborative creative processes have on their socialisation, motivation, and the practical implementation of acquired knowledge. The action research methodological framework was implemented in a Year 5 elementary school class during the 2017/2018 school year. The goal of the paper is to examine the potential for encouraging collaborative creativity in regular music teaching, as well as to indicate objective difficulties in undertaking this type of creative process in schools.

KRSTINIĆ, Marija
Ekstrinzična i intrinzična motivacija za učenje stranog jezika u poslovnom okruženju [Elektronička građa] / Marija Krstinić, Maja Pauković. - Graf. prikazi.
Bibliografija: 9 jed. - Sažetak ; Summary. - Motivacija predstavlja psihološki proces ili stanje unutar pojedinca koje potiče, usmjerava i postojano održava dobrovoljno ponašanje i akcije usmjerene prema određenom cilju. Kao temeljna i cjeloživotna potreba kojom usvajamo navike, znanja, vještine i sposobnosti te razvijamo kreativne mogućnosti, zahtijeva određenu razinu ulaganja intelektualnog napora, koncentracije i upornost koji ukazuju na kvalitetu učenja, a kolika će ona biti ovisi o razini i vrsti motivacije, kao ključnog pokretača tog procesa. U ovom radu će se opisati intrinzična i ekstrinzična motivacija, koje su međusobno isprepliću i prožimaju i na različite načine potiču na promjene ponašanja i aktivnosti određujući smjer, intenzitet i trajanje motivacije. Intrinzična se motivacija temelji na individualnoj percepciji i psihološkim procesima koji se zbivaju unutar svakog pojedinca i predstavlja sve ono što nas iznutra potiče kako bi se zadovoljile brojne unutarnje potrebe kao što su fiziološke, psihološke i socijalne potrebe i postigao osjećaj unutarnjeg zadovoljstva. Ekstrinzična motivacija predstavlja sve one poticaje koji su rezultat vanjskih utjecaja i stimulansa koji dolaze iz socijalnog i često poslovnog okruženja, a koji se uvijek vežu uz neki oblik nagrade i pohvale. Motivacija kao jedan od afektivnih čimbenika ima veliku važnost za učenje stranog jezika koje znatno utječe na volju i spremnost studenata u prihvaćanju novih znanja. U ovom radu provedeno je istraživanje na uzorku od 120 redovnih i izvanrednih studenata 1. godine Elektrotehničkog odjela Tehničkog veleučilišta u Zagrebu, u razdoblju od siječnja do svibnja 2018. godine. - Motivation represents a psychological process or condition within the individual that encourages, directs and continuously maintains a voluntary behavior and actions directed towards a specific goal. As a basic and lifelong need to acquire habits, knowledge, skills and abilities, and develop creative possibilities, it requires a certain level of investment of intellectual effort, concentration and perseverance. They determine the quality of learning and how much a person learns depends on the level and type of motivation, which is the key driver of this process. This paper will describe intrinsic and extrinsic motivation, which are mutually intertwined and pervasive, and in different ways encourage changes in behavior and activity by determining their direction, intensity and duration. Intrinsic motivation is based on individual perception and psychological processes and represents everything inside us encouraged to meet many internal needs, such as physiological, psychological and social, and achieve a sense of inner satisfaction. Extrinsic motivation represents all the incentives that are the result of external influences and stimuli that come from the social and often the business environment, and it is always associated with some form of awards and approvals. Motivation, as one of the affective factors, is of great importance in learning a foreign language, which significantly affects the willingness and readiness of students to accept new knowledge. In this paper, a survey was conducted on a sample of 120 full-time and part-time students of the first year at the Electrical Engineering Department at the Zagreb University of Applied Sciences, in the period from January to May 2018. The research aimed to show the impact of extrinsic and intrinsic motivation on English language learning.

The European dimension in education in geography textbooks for Croatian primary schools [Elektronička građa] : lessons learned and future expectations / Bojana Vignjević Korotaj, Jasminka Ledić, Ivana Miočić. - Graf. prikazi.
Bilješke uz tekst. - Bibliografija: str. 190-192. - Summary ; Sažetak. - Croatia's accession to the EU brought changes in educational policies by introducing the concept of the European Dimension in Education (EDE). EDE has successfully found its way into the new Croatian national curriculum, however, there has been no comprehensive analysis of whether it has been introduced into teaching materials (textbooks). Therefore, the aim of this paper is to determine if the European Dimension in Education is present in geography textbooks for primary schools, as well as to explore how it is represented in them. The results of research show that the idea of the European Dimension in Education is most commonly present in terms of factual knowledge about Europe, which does not motivate teachers and pupils to actively and critically discuss issues related to Europe and the European Union. - Pristupanje Republike Hrvatske članstvu u Europskoj uniji, donijelo je, između ostalog, promjene u obrazovnim politikama putem koncepta europske dimenzije u obrazovanju. Koncept europske dimenzije u obrazovanju uspješno pronalazi svoje mjesto u Nacionalnom okvirnom kurikulumu, međutim ne postoje detaljnije analize putem kojih bi se utvrdilo je li ovaj koncept prepoznat i u nastavnim materijalima, točnije u udžbenicima. Stoga je cilj ovog istraživanja utvrditi je li i na koji način europska dimenzija u obrazovanju prisutna u udžbenicima geografije za osnovnu školu. Rezultati istraživanja pokazali su da je ideja europske dimenzije u obrazovanju dominantno prisutna u obliku činjeničnog znanja o Europi što nastavnicima i učenicima ne pruža dovoljno mogućnosti za razvoj stavova i kritičkog osvrta na spomenute teme.

GURASHI, Romina
How important is culture? [Elektronička građa] : analysis of the most recent data on Italian educational offer and its impact on employment and employability / Romina Gurashi, Andrea Grippo. - Graf. prikazi.
Bilješke uz tekst. - Bibliografija: 61 jed. - Summary ; Sažetak. - In a globalised world where competitiveness represents the keystone of modern capitalist society and thus of economic health and prosperity, knowledge and expertise express the very differentiating element between successful and unsuccessful economic performance. In a systemic perspective, the ever-changing character of our society imposes a continuous reorientation of the processes of knowledge transmission to tackle the increasing challenges posed by interrelated labour markets. In the academic field, this involves the use of multi- and transdisciplinary approaches in research and education. In the light of the assumption that the economy is not a self-standing subject but it dialectically interacts with the socio-cultural phenomena, the researchers will provide an in-depth analysis of the most recent data on the relationship between economics and culture. This article is the result of analytical research, conducted by using the mixed research methodology. The primary and secondary data are used, as well as do an extensive bibliographic research. The analysis offered is functional, in order to determine a correlation between economics and culture. By examining the specific outcome of the educational system, the researchers will give important insights into the capacity of the Italian educational system to address new needs of labour markets, i.e. to support the employment rate of recent graduates. This work further aims to verify the hypothesis of a positive correlation between economic performance and educational level. The main research limitation might be related to the fact that this study offers a national overview of the phenomenon, leaving aside any regional or local specificity. The original value of this work lays in the test of the theory recognizing a connection between changes in the labour market and in Italian educational system. - U globaliziranom svijetu, u kojem je konkurentnost temelj modernog kapitalističkog društva, a time i ekonomskog zdravlja i prosperiteta, znanje i stručnost razlikovni su element između izvrsnih i loših ekonomskih rezultata. U sistemskoj perspektivi, naše društvo koje se stalno mijenja, nameće kontinuiranu reorijentaciju procesa prijenosa znanja kako bi riješio sve veće izazove koje međusobno povezana tržišta rada postavljaju. U akademskom području to uključuje upotrebu multi- i trans-disciplinarnih pristupa istraživanju i obrazovanju. U svjetlu pretpostavke da ekonomija nije samostojeći subjekt, već da dijalektički komunicira sa socio-kulturnim fenomenima, autori donose detaljnu analizu najnovijih podataka o odnosu ekonomije i kulture. Ovaj članak rezultat je analitičkog istraživanja koje je provedeno primjenom mješovite metodologije. Autori provode istraživanje korištenjem primarnih i sekundarnih podataka, te vršeći opsežno istraživanje literature. Prikazana analiza će funkcionalno utvrditi korelaciju između ekonomije i kulture. Ispitujući specifične ishode obrazovnog sustava, autori će dati važan uvid u sposobnost talijanskog obrazovnog sustava da odgovori na nove potrebe tržišta rada, tj. da održi stopu zaposlenosti nedavno diplomiranih studenata. Ovaj rad nadalje ima za cilj provjeriti hipotezu o pozitivnoj korelaciji između ekonomske uspješnosti i obrazovne razine. Glavno ograničenje istraživanje bi moglo biti povezano s činjenicom da ovo istraživanje donosi nacionalni pregled, zanemarujući bilo koju regionalnu ili lokalnu specifičnost. Izvorna vrijednost ovog rada leži u testiranju teorije koja prepoznaje vezu između promjena na tržištu rada i talijanskog obrazovnog sustava.

Ideološki sukobi i obrazovanje u Hrvatskoj [Elektronička građa] : studija slučaja Cjelovite kurikularne reforme kroz prizmu teorije konzervativne modernizacije Michaela Applea / Lucija Šikuten. - Graf. prikazi.
Bibliografija i i nternetski izvori: str. 85-87. - Sažetak ; Summary. - Ovaj rad istražuje ideološke sukobe vezane za pokušaj implementacije Cjelovite kurikularne reforme u Hrvatskoj, s ciljem evaluacije procesa konzervativne modernizacije, teorijski elaboriranog u radu Michaela Applea. Rad se temelji na metodi studije slučaja i kvalitativnoj analizi sadržaja. Analizirani sadržaji bili su članci triju najčitanijih novinskih portala u Hrvatskoj, mrežne stranice istaknutih aktera te Okvir nacionalnog kurikuluma. Analizom prikupljenih podataka dolazi se do zaključka da su u javne rasprave uključeni predstavnici svih grupa konzervativne modernizacije, no ne u jednakoj mjeri, te nemaju sva obilježja o kojima govori Apple. U raspravama su najistaknutije međusobno isprepletene grupe neokonzervativaca i (religijskih) autoritarnih populista, koje se zalažu za očuvanje hrvatskog identiteta i kršćanske tradicije u obrazovanju. Unatoč prisutnosti brojnih elemenata pokreta konzervativne modernizacije, još ih je uvijek nedovoljno da bismo u potpunosti potvrdili njegovo djelovanje – u radu se zamjećuje izostanak većeg utjecaja neoliberalne politike u obrazovanju, koji bi potaknuo tržišno natjecanje. No, zaključak rada jest da se Hrvatska, kao zemlja u razvoju, kreće u tom smjeru. - This paper aims to explore ideological conflicts related to the attempted implementation of the Complete Curricular Reform in Croatia. This analysis is used as a basis for the evaluation of the process of conservative modernisation, as theorised by Michael Apple. The paper is based on the case study methodology and qualitative content analysis. The analysed contents were articles from the three most widely read news sites in Croatia, websites of prominent actors and the document of the National Curriculum Framework. The paper argues that the representatives of all groups pushing for a conservative modernisation were part of the public debate, but they were not all equally represented, nor did they demonstrate all the characteristics identified by Apple. The most prominent groups in the debate were the mutually related groups of neo-conservatives and (religious) authoritarian populists, who are committed to preserving the Croatian identity and the Christian tradition in education. Although the analysis identifies many elements of conservative modernisation, these are still not sufficient to fully confirm its presence in Croatia. Specifically, what is missing is a greater influence of the neoliberal policy in education that would be included in market competition. However, it seems that Croatia is moving in that direction.

KISS, Irena
Intersubjektivnost i komunikacijska dinamika u obrazovanju za poduzetništvo [Elektronička građa] / Irena Kiss. - Graf. prikazi.
Bibliografija: 13 jed. - Sažetak ; Summary. - Interpersonalne vještine prvi su i osnovni preduvjet ostvarenju profesionalnih ciljeva pojedinca gotovo u svim zanimanjima, a posebno u onim u čijim se središtima nalaze ljudi. Kada je riječ o edukativnim programima koji obuhvaćaju poduzetničke teme, temeljni komunikacijski preduvjeti odnose se na kombinaciju vještina slušanja, opažanja i razumijevanja, kao i prenošenje ideja i emocija na način prikladan određenoj ciljnoj skupini. Stavovi o navedenoj temi osnovna su tema istraživanja „Utjecaj društvenih mreža na razvoj komunikacije“, provedenog među 142 osobe koje u okviru svoje edukacije slušaju predmet poduzetništvo. Istraživanjem su obuhvaćeni polaznici programa prekvalifikacije u izobrazbi odraslih (29%) i učenici završnih razreda srednje strukovne škole (71%). Rezultati provedenog istraživanja obrađeni su kombinacijom empirijske, komparativne i deskriptivne metode. Odgovori ispitanika ukazali su, između ostaloga, na sve veću zastupljenost virtualnog načina komuniciranja, koji zbog svoje brzine i praktičnosti postaje sveprisutan i nezamjenjiv te, s druge strane, na sve otežaniji verbalni izričaj kao njegovu izravnu posljedicu. - Interpersonal skills are the first precondition for the achievement of professional goals in almost all occupations, especially those where people are in the center. When it comes to entrepreneurship education, basic communication prerequisites relate to the skills of listening, observing, understanding and communicating ideas and emotions in a way that is appropriate for the target group. The views on this topic are the basis of the study “The Impact of Social Networks on Communication Development”, conducted among 142 people who study entrepreneurship as a part of their education. Students in prequalification programs in adult education (29%) and upper secondary school students (71%) are included. The results of the research were analyzed using a combination of empirical, comparative and descriptive methods. They pointed to the increasing prevalence of virtual communication, which became irreplaceable due to speed and convenience, but also made it difficult to verbally express something consequently.

Ispitivanje interesa i zadovoljstva nastavom likovne umjetnosti kao poticaja za razvoj sposobnosti učenja ostalih nastavnih predmeta [Elektronička građa] / Miroslav D. Drljača, Siniša Opić, Milan Matijević. - Graf. prikazi.
Bibliografija: str. 210-212. - Sažetak ; Summary. - Istraživanje je provedeno na uzorku učenika trećih razreda strukovnih škola i gimnazija (N=605). Od uključenih učenika, gimnaziju je pohađalo njih 253, a srednje strukovne škole 352 učenika. Cilj istraživanja bio je ispitati neke specifičnosti u percepciji učenika srednjih škola o važnosti nastavnih predmeta iz područja likovnih umjetnosti. Napravljena je posebna analiza samo za dvije odabrane zavisne varijable: važnost nastavnih predmeta iz područja likovnih umjetnosti za razvoj pamćenja i sposobnosti za učenje ostalih nastavnih predmeta te interes i zadovoljstvo sudjelovanjem u likovnim aktivnostima. Rezultati pokazuju da ne postoji statistički značajna razlika između učenika gimnazija i strukovnih škola u procjeni sudjelovanja u aktivnostima nastave likovne umjetnosti te u procjeni važnosti likovnih aktivnosti za razvoj pamćenja i sposobnosti za učenje ostalih predmeta. Postoji statistički značajna spolna razlika u procjeni sudjelovanja u aktivnostima nastave likovne umjetnosti te u procjeni važnosti likovnih aktivnosti za razvoj pamćenja i sposobnosti za učenje ostalih predmeta. Može se zaključiti da ispitanici nisu bili u mogućnosti procijeniti koliko i u koju svrhu će im u daljnjem školovanju i budućem zanimanju koristiti kompetencije stečene u nastavi likovne umjetnosti. - This research was carried out on a sample of third year pupils of vocational schools and gymnasiums (N=605). Of the surveyed pupils, 253 of them attended gymnasiums, while 352 attended vocational secondary schools. The goal of this research was to examine specificities in secondary school pupils’ perceptions of the importance of subjects in the field of the fine arts. A separate analysis was undertaken for only two selected dependent variables: the importance of subjects in the field of the fine arts for developing memory and the ability to learn other subjects, and interest in and satisfaction with participation in fine arts activities. The results show that there is no statistically significant difference between the estimation of gymnasium and vocational school pupils regarding participation in fine arts activities or in their estimation of the importance of fine arts activities in developing memory and the ability to learn other subjects. There is a statistically significant gender difference in the estimation of participation in fine arts activities, as well as in the estimation of the importance of fine arts activities in developing memory and the ability to learn other subjects. It can be concluded that respondents were unable to estimate how much or why they would use competencies gained in fine arts teaching in their continued education or their future careers.

Karakteristike demokratske školske kulture i demokratskoga školskog vođenja u osnovnim školama iz učiteljske perspektive [Elektronička građa] / Monika Pažur. - Graf. prikazi.
Bibliografske bilješke uz tekst ; bibliografija: str. 69-73. - Sažetak ; Summary. - U radu je prikazano istraživanje u kojem se ispitivala razvijenost i karakteristike određenih obilježja demokratske školske kulture i demokratskog školskog vođenja u osnovnim školama. U istraživanju je sudjelovao 651 učitelj iz Grada Zagreba i Zagrebačke županije. Istraživanje je provedeno anketnim ispitivanjem putem upitnika koji je sadržavao Instrument za mjerenje obilježja demokratskog školskog vođenja (izrađen za potrebe istraživanja) i Instrument za mjerenje obilježja demokratske školske kulture (preuzet iz: Spajić-Vrkaš, 2016). Ukupno gledano, rezultati pokazuju da učitelji percipiraju vođenje u njihovoj školi kao umjereno demokratsko do vrlo demokratsko. Procjenjujući obilježja školske kulture, učitelji primjećuju umjerenu razvijenost demokratskih, ali i nedemokratskih obilježja školske kulture. Međutim, ipak u većoj mjeri smatraju da njihova školska kultura posjeduje ona obilježja koja je čine demokratskom. Veću razvijenost obilježja demokratskog školskog vođenja percipiraju učitelji koji su na početku svoje karijere i oni koji su zaposleni u školama u kojima je aktualni ravnatelj na toj poziciji kraće od pet godina. Veću razvijenost obilježja demokratske školske kulture percipiraju učitelji zaposleni u prigradskim i malim školama. - This paper describes research into the development and characteristics of particular qualities of democratic school culture and democratic school management in primary schools. The research involved 651 teachers from the City of Zagreb and Zagreb County. Research involved a survey that used a questionnaire containing the Instrument for measuring characteristics of democratic school management (created for the needs of this research) and the Instrument for measuring the characteristics of democratic school culture (taken from Spajić- Vrkaš, 2016). Overall, the results show that teachers perceive management in their schools as moderately democratic to very democratic. Rating the characteristics of school culture, teachers note the moderate development of both democratic and non-democratic characteristics of school culture; however, they more greatly consider their own school culture to possess democratic characteristics. Teachers at the beginning of their careers and those employed in schools whose current headmaster has been in his/her position less than five years perceive higher levels of democratic school management. Teachers employed in suburban or small schools perceive higher levels of characteristics of democratic school culture.

Potential use of music therapy elements in music teaching [Elektronička građa] / Martina Metić, Vesna Svalina. - Graf. prikazi.
Bibliografija: str. 170-172. - Summary ; Sažetak. - Recent scientific studies have shown that involving children in music activities influences their mental, emotional, and social development; music is, thus, being used increasingly for medical and therapeutic purposes. In order to discover whether some elements of particular methods of music therapy can be applied in music teaching in primary schools, we conducted a qualitative research in which the participants were third-year elementary school pupils in Osijek. To collect the data, we used a systematic observation procedure. Data analysis involved both qualitative and quantitative analyses. The research results show that the introduction of elements of certain methods of music therapy is possible and that pupils are happy to participate in all the activities carried out. In doing so, pupils demonstrate imagination, creativity, independence at work, and willingness to cooperate. - Novija znanstvena istraživanja pokazuju da uključivanje djece u glazbene aktivnosti utječe na njihov psihički, emocionalni i socijalni razvoj zbog čega se glazba sve više koristi i u medicinske, odnosno terapeutske svrhe. Kako bismo saznali je li moguće neke elemente iz pojedinih metoda glazboterapije primijeniti i u nastavi glazbe u osnovnoj općeobrazovnoj školi, proveli smo kvalitativno istraživanje u kojemu su sudionici bili učenici trećeg razreda jedne osnovne škole iz Osijeka. Za potrebe prikupljanja podataka koristili smo postupak sustavnog promatranja, a za analizu podataka kvalitativnu i kvantitativnu analizu. Rezultati istraživanja pokazali su da je uvođenje elemenata iz pojedinih metoda glazboterapije moguće te da učenici rado sudjeluju u svim provedenim aktivnostima. Pritom učenici iskazuju maštovitost, kreativnost, samostalnost u radu te spremnost na suradnju.

Stavovi studenata nastavničkih studija prema nastavničkoj naobrazbi [Elektronička građa] : primjer dvaju zagrebačkih sveučilišta / Dunja Jurić Vukelić, Rona Bušljeta Kardum. - Graf. prikazi.
Bibliografija: str. 144-146. - Sažetak ; Summary. - Danas su nastavnici suočeni s brojnim izazovima, posebice u Hrvatskoj u kojoj je u tijeku provođenje opsežne reforme obrazovanja. Reforma obrazovanja stavila je u prvi plan drugačiju paradigmu procesa podučavanja i učenja koja zahtijeva od nastavnika neka nova znanja i vještine. Studije i analize pokazale su kako su upravo nastavnici najvažniji faktor ostvarenja obrazovnih ciljeva učenika. Pored stručnih kompetencija, za razvoj znanja, umijeća i stavova učenika od velike su važnosti i pedagoško-psihološko-didaktičko-metodičke kompetencije nastavnika. U ovom se radu uz pomoć podataka prikupljenih upitnikom na uzorku od 115 studenata željelo detektirati u kojoj su mjeri studenti dviju visokoškolskih institucija – Fakulteta hrvatskih studija i Hrvatskog katoličkog sveučilišta – zadovoljni inicijalnom nastavničkom naobrazbom te smatraju li je pogodnom i dovoljnom za izazove koje nosi njihovo buduće zanimanje. Rezultati provedenog istraživanja pokazuju da su studenti u prosjeku zadovoljni kvalitetom studija i nastavničke naobrazbe te da preferiraju postojeći model stjecanja pedagoških kompetencija uz predmetni studij. Rezultati istraživanja analizirani su u kontekstu ispitivanja potrebe za sadržajnim i praktičnim osmišljavanjem novog načina stjecanja nastavničkih kompetencija, odnosno dorađivanjem ili proširivanjem studija nastavničke naobrazbe. - Today, teachers are faced with numerous challenges, especially in Croatia, where extensive educational reform is underway. Education reform has placed a new teaching and learning paradigm in the foreground that demands new knowledge and skills from teachers. Studies and analyses show that teachers are the most important factor in reaching pupils’ educational goals. In additional to professional competencies, pedagogical, psychological, didactic, and methodical teacher competencies are of great importance to the development of knowledge. Using survey data from a sample of 115 students, this paper examines the extent to which students of two institutions of higher education – the Faculty of Croatian Studies and the Catholic University of Croatia – are satisfied with their initial teacher education, and whether they consider it appropriate and sufficient for the challenges their future careers hold. The results of this research show that students are, on average, satisfied with the quality of their studies and teacher education, as well as that they prefer the existing pedagogical competency attainment model that is added to the regular subject study. The research results are analysed in the context of examining the need for a new design of such programmes, their refinement or expansion of teacher education study programmes.

Teaching as a calling and well-being of Slovenian and Croatian teachers [Elektronička građa] / Polona Gradišek, Sonja Pečjak, Majda Rijavec, Lana Jurčec. - Graf. prikazi.
Bibliografija: str. 265-267. - Summary ; Sažetak. - In a sample of 347 elementary school subject teachers from Slovenia (N = 176) and Croatia (N = 171), the authors investigated teachers’ orientations to work (as a job, a career, and a calling) and their well-being with respect to different stages of teachers’ professional development. Results have shown the presence of a calling orientation to work and its positive relationship to job satisfaction and life satisfaction. Although significant differences between Slovenian and Croatian teachers were not expected due to shared historical, cultural and political background, some interesting differences were observed. The results of MANOVA showed that teachers differed significantly in their work orientations regarding nationality and the length of their working experience. Results were discussed in the context of stages of professional development and the social status of teachers in both countries. - Na uzorku od 347 nastavnika predmetne nastave iz Slovenije (N = 176) i Hrvatske (N = 171) autori su ispitivali odnos orijentacije nastavnika prema radu (kao posao, karijera i poziv) i njihove dobrobiti u različitim fazama profesionalnog razvoja. Prema dobivenim rezultatima izdvaja se orijentacija prema radu kao pozivu, koja je u pozitivnoj vezi s većim zadovoljstvom poslom i zadovoljstvom životom. Iako se, zbog zajedničke povijesne, kulturne i političke pozadine, nisu očekivale značajne razlike između slovenskih i hrvatskih nastavnika, ipak su uočene neke zanimljive razlike. Rezultati MANOVE pokazali su da su se nastavnici značajno razlikovali u svojim orijentacijama prema radu, ovisno o državljanstvu i duljini radnog iskustva. O rezultatima se raspravlja u kontekstu razumijevanja faza profesionalnog razvoja i socijalnog statusa nastavnika u obje zemlje.

Gimnazija ili četverogodišnja strukovna škola? [Elektronička građa] : Osobne i socijalne odrednice odabira vrste srednjoškolskog obrazovanja / Josip Šabić, Jelena Matić Bojić, Iris Marušić. - Graf. prikazi.
Bibliografija: str. 156-158. - Sažetak ; Summary. - Integrativni teorijski modeli, poput socijalno-kognitivne teorije obrazovnih i karijernih izbora, prepoznaju brojnost i složenost odrednica učeničke odluke o odabiru vrste srednjoškolskog obrazovanja. No, malobrojna su istraživanja u kojima se istodobno provjeravao doprinos većeg broja odrednica te odluke. Cilj ovog rada je istražiti doprinos različitih osobnih i socijalnih odrednica učeničkog odabira gimnazijskog ili četverogodišnjeg strukovnog obrazovanja; obrazovnih odabira koji omogućuju izravnu prohodnost prema visokom obrazovanju. Osobne su odrednice spol, školski uspjeh, akademska samoefikasnost, samopoštovanje te čimbenici odabira srednjoškolskog obrazovanja, dok su socijalne odrednice učeničke procjene radnog i obrazovnog statusa roditelja te srednjoškolske aspiracije roditelja za dijete. U istraživanju su korišteni podatci prikupljeni upitnicima na učenicima 7. i 8. razreda 23 zagrebačke osnovne škole (N=784). Testiran je binarni logistički model kojim je ispitan relativni doprinos odrednica u objašnjenju odabira vrste srednjoškolskog obrazovanja. Od osobnih odrednica ulogu u učeničkim odabirima imaju spol, školski uspjeh i samoefikasnost. Četverogodišnje strukovno obrazovanje češće žele upisati mladići, učenici/ce nižeg uspjeha i niže samoefikasnosti. Među socijalnim odrednicama ulogu imaju radna aktivnost majke i srednjoškolska aspiracija roditelja za dijete. Četverogodišnje strukovno obrazovanje češće žele upisati učenici/ce čije su majke radno neaktivne, čiji roditelji žele da oni upišu četverogodišnje strukovno obrazovanje te učenici/ce koji nisu upoznati s aspiracijama svojih očeva za njih. Rezultati potvrđuju dosadašnje nalaze o povezanosti individualnih varijabli poput školskog uspjeha i samoefikasnosti s namjerama učenika vezanim za upis gimnazijskoga ili četverogodišnjeg strukovnog obrazovanja. - Integrative theoretical models, such as the social cognitive theory of career and academic choices, recognise the complexity of determinants of students’ decisions about the choice of secondary education. However, few studies have simultaneously examined the contribution of several determinants of this choice. This paper aims to examine the contribution of different personal and social determinants of students’ choices of grammar school or four-year vocational secondary education ─ educational programs that allow direct access to higher education. Personal determinants are gender, school achievement, academic self-efficacy, self-esteem, and factors related to the choice of secondary education, while social determinants are students' reports of their parents' work status, educational status, and secondary school aspirations for the child. The data were collected by questionnaires administered on 7th- and 8th-grade students in 23 elementary schools in Zagreb (N = 784). A binary logistic model was tested, examining the relative contribution of the determinants in explaining the choice of the type of secondary education. Among the personal determinants, gender, school achievement, and self-efficacy play a role in student choices. Four-year vocational education is more often chosen by male students and students with lower school achievement and lower self-efficacy. Significant social determinants are the mother's work status and the parents' secondary school aspirations for their child. Four-year vocational education is more often chosen by students whose mothers do not work, whose parents prefer their enrolment at four-year vocational education, and who are unfamiliar with their fathers' aspirations for them.

ICT in the primary school [Elektronička građa] : practice and attitudes of informatics teachers / Darko Dukić, Slavko Petrinšak, Pavao Pinjušić. - Graf prikazi.
Bibliografija: 24 jed. - Abstract. - The aim of the study was to explore various issues related to the introduction and use of ICT in primary schools in eastern and central Croatia from the viewpoint of informatics teachers. A total of 232 respondents participated in the survey. Both descriptive and inferential statistics were applied in data analysis. The results indicate that the equipment in computer classrooms is only partially satisfactory. LCD projectors and multimedia computers are mostly used in teaching informatics. The research also revealed that teachers are aware of the importance of ICT implementation in classrooms. However, they are less satisfied with the professional development opportunities. Their responses also suggest that they are ready to participate in the curriculum development process, undertake continuing education, and focus on pupils and their learning. In addition, the analysis showed that teachers, regardless of their background characteristics, share similar views. So far, the issues discussed in this paper have only been superficially examined. The present study expands previous research by providing insight into the practice and attitudes of informatics teachers in Croatian primary schools.

Jednaki i jednakiji [Elektronička građa] : perspektive ravnatelja o državnoj maturi i mogućnostima ostvarivanja visokoškolskih aspiracija učenika strukovnih i gimnazijskih programa u Hrvatskoj / Nikola Baketa, Zrinka Ristić Dedić, Boris Jokić. - Graf. prikazi.
Bibliografija: str. 246-249. - Sažetak ; Summary. - U radu su predstavljeni rezultati kvalitativnog eksploratornog istraživanja perspektive ravnatelja srednjih škola o modelu državne mature te jednakosti i pravičnosti u mogućnosti pristupa visokom obrazovanju za učenike strukovnih škola i gimnazija. Ova se pitanja analiziraju u kontekstu sve izraženijih aspiracija mladih ljudi prema visokom obrazovanju, masifikacije visokog obrazovanja i strateškog određenja Republike Hrvatske prema povećanju udjela visokoobrazovanih građana. Jednakost mogućnosti pristupa visokom obrazovanju podrazumijeva da svi učenici koji žele studirati imaju pravo pod jednakim uvjetima i kriterijima pristupiti državnoj maturi kao preduvjetu za upis visokog obrazovanja, a pitanje pravičnosti ogleda se u tome da svaki učenik ima jednaku mogućnost uspjeha u pristupu visokom obrazovanju. Rezultati ukazuju na općenito pozitivne stavove ravnatelja o državnoj maturi kao jedinstvenom sustavu vanjskih ispita koji omogućuje provjeravanje stečenih znanja i vještina na isti način i uz iste kriterije za sve učenike. Kritičke perspektive ravnatelja odnose se na preispitivanje primjerenosti certifikacijske funkcije državne mature za učenike gimnazija (ravnatelji gimnazija) te slabljenja selekcijske funkcije korištenjem dodatnih provjera znanja i sposobnosti učenika od strane visokoškolskih institucija (ravnatelji različitih vrsta škola). Perspektive ravnatelja gimnazija i strukovnih škola o jednakosti i pravičnosti u mogućnostima pristupu visokom obrazovanju izrazito se razlikuju. Dok ravnatelji gimnazija pravičnost sagledavaju kroz prizmu osiguravanja jednakih uvjeta i kriterija za sve, ravnatelji strukovnih škola prepoznaju da nedostatak pravičnosti proizlazi iz drugačijeg obrazovnog iskustva i opsega onoga što uče učenici strukovnih programa. - The paper presents the results of a qualitative exploratory study of secondary school principals’ perspectives on the State Matura model, and the issues of equality and equity of access to higher education for vocational and grammar school pupils. These questions are analysed in the context of increasing aspirations of young people towards higher education, the massification of higher education, and the strategic positioning of the Republic of Croatia towards increasing the share of highly educated citizens. Equality of access to higher education implies that all pupils who wish to study have the right to access the State Matura, a prerequisite for entering tertiary education, under equal conditions and criteria. The issue of equity means that every pupil has an equal opportunity to access tertiary education. The results point to generally positive attitudes regarding the State Matura as a uniform system of external exams that enables assessment of the acquired knowledge and skills in the same manner and using the same criteria for all pupils. Principals’ critical perspectives include questioning the suitability of the certification function of the State Matura for grammar school pupils and the weakening of the selective function due to additional testing of pupils’ knowledge and skills by tertiary education institutions. The perspectives of grammar school and vocational school principals on equality and equity of access to tertiary education are distinctly different. While grammar school principals view equity through the prism of providing equal conditions and criteria for all, vocational school principals recognise that the lack of equity arises from a different educational experience and the scope of what is taught in vocational programmes. Existing educational policy mechanisms aimed at addressing the less favourable status of vocational school pupils are insufficient to equalise the opportunities of pupils from various secondary school programmes.

Slika suvremenog odgojitelja u paradigmi ranog i predškolskog odgoja i obrazovanja [Elektronička građa] / Željka Pintar.
Bibliografija: str. 99-103. - Sažetak ; Summary. - U radu se tematizira preobrazba tradicionalnog odgojitelja biheviorističke odgojno-obrazovne paradigme, svojstvene socijalističkom razdoblju u Republici Hrvatskoj, u suvremenog odgojitelja, zagovornika konstruktivističkog odgojno-obrazovnog koncepta, svojstvenog razdoblju demokratskog života u istom kontekstu. U radu se nastoji uputiti na ključne razlike između tradicionalnog i suvremenog odgojitelja, a ujedno i na njihove srodnosti, kako bi se bolje razumjela očekivanja i kriteriji za procjenu uspješnosti djelovanja u aktualnoj odgojno- obrazovnoj djelatnosti. Tematizira se implicitna pedagogija kao odgojiteljeva subjektivna odgojno-obrazovna teorija te se ukazuje na opravdanost shvaćanja implicitne pedagogije kao ključnog konstrukta odgojno-obrazovnog koncepta. Također se upućuje i na važnost refleksivne prakse kao sastavnice odgojiteljeva profesionalnoga razvoja te se problematizira provedba akcijskih istraživanja kao instrumenta razvoja odgojiteljeve djelatnosti. - This paper discusses the transformation of a traditional educator in behaviorist educational paradigm, which was characteristic to a socialist period in the Republic of Croatia, into a modern one, who is an advocate of a constructivist educational concept, characteristic to the period of democratic life. The paper addresses key differences and similarities between traditional and modern educators in order to better understand expectations and criteria for successful performance in the contemporary educational activity. Implicit pedagogy is also discussed as an educator’s subjective educational theory. The justification of its understanding as a key construct of the educational concept is pointed out. The paper also emphasizes the importance of reflective practice as a component of educator’s professional development, and problematizes implementation of action research as an instrument for development of educator’ s activity.

Auditory processing in people with chronic aphasia [Elektronička građa] / Katarina Pavičić Dokoza, Zdravko Kolundžić, Mladen Heđever. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - The preconditions for successful voice communication are good hearing and listening, and auditory processing that includes the ability to process the audio signal. Damage or deceleration of sound signal processing at any level from the periphery to the central structures leads to disintegration and inability to process the signal effectively. Auditory processing in people with aphasia has not been examined in Croatia to date. Results of studies conducted in other languages point to negative effects of auditory processing difficulties on the receptive and expressive component of the language. This study was conducted on a sample of subjects with chronic aphasia and a group of control subjects with no neurological or any other disorders that can affect auditory processing. The inclusion criteria for persons with aphasia were impaired language skills as a result of cerebrovascular accident that occurred at least six months before the examination, regardless of severity and type of aphasia and normal hearing status. The study did not include persons with aphasia who were unable to repeat the six-word sentence, due to impaired comprehension or speech expression, and those whose comprehension was not sufficient to cooperate well during the test. The test was conducted individually for 30 minutes per subject using the Auditory processing test (PSP) that is standardized for the Croatian language. Results from this study showed statistically significant lower achievement on all subtests on PSP-1 (filtered words, speech in noise, dichotic words test, and dichotic sentence test) in people with aphasia compared with the control group. People with aphasia and control group subjects showed better results in favor of the left ear on variable speech in noise. Filtered words were easily processed through the left ear in people with aphasia while dichotic sentences were easily processed through the left ear in the control group. - Preduvjeti uspješne govorne komunikacije su dobar sluh i slušanje, te slušno procesiranje koje uključuje sposobnost obrade zvučnog signala. Oštećenja ili usporavanja obrade zvučnog signala na bilo kojoj razini od periferije do središnjih struktura dovodi do dezintegracije i nemogućnosti učinkovite obrade signala. U Hrvatskoj do sada nije ispitivano slušno procesiranje kod osoba s afazijom. Rezultati istraživanja provedenih u drugim jezicima upućuju na negativan utjecaj poremećaja slušnog procesiranja na receptivnu i ekspresivnu sastavnicu jezika. Istraživanje je provedeno na uzorku ispitanika s kroničnom afazijom i skupini kontrolnih ispitanika bez neuroloških ili drugih bolesti koje mogu utjecati na slušno procesiranje. Kriteriji uključivanja osoba s afazijom su bili sljedeći: slabije jezične sposobnosti kao posljedica CVI koji se dogodio najmanje šest mjeseci prije ispitivanja bez obzira na težinu i vrstu afazije te uredan sluh. U istraživanje nisu uključene osobe s afazijom koje nisu bile u mogućnosti za ispitivačem ponoviti rečenicu od šest riječi, bez obzira radi li se o poremećaju razumijevanja ili govorne ekspresije, te osobe kod kojih razumijevanje nije bilo dovoljno za dobru suradnju tijekom provođenja testa. Ispitivanje je provedeno individualno u trajanju od tridesetak minuta po ispitaniku pomoću testa PSP-1 koji je standardiziran za hrvatski jezik. Dobiveni rezultati pokazuju statistički značajno slabija postignuća na svim subtestovima Testa slušnog procesiranja (filtrirane riječi, govor u buci, dihotički test riječi, dihotički test rečenica) kod osoba s afazijom u odnosu na kontrolne ispitanike. Osobe s afazijom i skupina kontrolnih ispitanika pokazuju statistički značajne razlike u smislu boljih rezultata na lijevom uhu na varijabli govor u buci.

LUKAŠ, Mirko
Povijesni diskurs stručnog usavršavanja i trajne izobrazbe nastavnika [Elektronička građa] / Mirko Lukaš.
Bibliografske bilješke uz tekst ; bibliografija: str. 99-101. - Sažetak ; Summary. - Usporednom analizom odabranih povijesnih i suvremenih pedagoških dokumenata stručno usavršavanje se prepoznaje kao trajna i neodvojiva komponenta nastavničke profesije. Trajno usavršavanje odgojnoobrazovnih djelatnika nepravedno se pripisuje tek vremenu paradigme cjeloživotnog obrazovanja. Pedagoški teoretičari nastavničkoj profesiji od njezinih početaka i pokušaja zakonske regulative te njezina društvenog etabliranja propisuju trajnu potrebu stručnog usavršavanja u svrhu profesionalnog razvitka i karijernog napredovanja, kao i obvezu neprestanog učenja. Već u prvom zakonskom dokumentu iz 1874. godine propisano je individualno i produžno obrazovanje svih učitelja. Time stručno usavršavanje postaje ključna sastavnica učiteljske profesije, a kasnije i svih odgojno obrazovnih djelatnika. Analizom povijesnih dokumenata utvrđena je sto pedeset godišnja zakonska i propisima regulirana trajna obveza stručnog usavršavanja nastavnika koja u praksi često nije ostvarena. Nakon dosegnute sveučilišne razine inicijalnog obrazovanja svih nastavnika i učitelja, potrebno je stvoriti uvjete za njihovo sustavno i učinkovito stručno usavršavanje. - By comparative analysis of selected historical and contemporary pedagogical documents, professional development is recognized as a permanent and inseparable component of the teaching profession. Continuous training of educators is unfairly attributed only to the time of the lifelong education paradigm. Since its beginnings and attempts at legislation and its social establishment, pedagogical theorists have prescribed the continuing need for professional development for the purpose of professional development and career advancement, as well as the obligation of continuous learning. Already in the first legal document of 1874, individual and extended education of all teachers was prescribed. In this way, professional development becomes a key component of the teaching profession and later of all educational staff. The analysis of historical documents has determined the one hundred and fifty-year legal and statutory regulation of a permanent obligation for the professional development of teachers, which is often not achieved in practice. After reaching the university level of initial education of all teachers, it is necessary to create the conditions for their systematic and effective professional development.

Factors affecting relative efficiency of higher education institutions of economic orientation [Elektronička građa] / Andrea Arbula Blecich. - Graf. prikazi.
Bibliografija: 54 jed. - Summary ; Sažetak. - This paper investigates the factors that influence the relative efficiency of higher education institutions of economic orientation. The empirical analysis is carried out on 31 higher educational institutions of economic orientation in Croatia, Slovenia and Bosnia and Herzegovina, in three phases. In the first phase, relative efficiency of observed institutions is evaluated for three main areas of their activities: teaching, research and international activity. In the second phase, higher education institutions are clustered based on relative efficiency results of each individual area of their activity. In the last, third phase, key association factors of a particular cluster are determined using univariate binary logistic regression and odds for transition to a more favourable cluster are defined. The results indicate that odds for positioning in the more efficient cluster are higher in public institutions than in private ones, in institutions with more published professional papers, in those with higher expenditures per faculty, the larger number of enrolled students per faculty, as well as in those with more visiting researchers. The proposed model can serve as a design guideline for education policies and as a moderation guideline for national authorities. - U ovom se radu analiziraju čimbenici, koji utječu na relativnu efikasnost visokoškolskih institucija iz područja ekonomije. Empirijska je analiza provedena na 31 visokoškolskoj ustanovi u Hrvatskoj, Sloveniji te Bosni i Hercegovini, u tri faze. U prvoj je fazi evaluirana relativna učinkovitost promatranih ustanova za tri ključna područja, i to: nastavu, istraživanje te međunarodnu suradnju. U drugoj je fazi izvršena analiza klastera, na temelju rezultata relativne učinkovitosti za tri prethodno navedena područja aktivnosti. U posljednjoj – trećoj fazi, ključni čimbenici pripadnosti određenom klasteru utvrđeni su korištenjem univarijantne binarne logističke regresije te su određene vjerojatnosti za prijelaz u povoljniji klaster. Rezultati pokazuju da je vjerojatnost pozicioniranja u efikasnijem klasteru veća u javnim, negoli u privatnim institucijama, u institucijama s više objavljenih stručnih radova, kao i onima s većim troškovima po nastavniku te s većim brojem upisanih studenata po nastavniku, a na kraju – i onima s većim brojem gostujućih istraživača. Predloženi model može poslužiti kao vodič za kreiranje obrazovnih politika.

Nastavne metode u edukaciji zdravstvenih djelatnika [Elektronička građa] / Ana Debeljak De Martini, Renato Ristić, Jasminka Potočnjak. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Sažetak ; Summary. - Edukacija zdravstvenih djelatnika kroz formalnu nastavu često se odvija ex cathedra, gdje predavač prenosi znanje, a studenti su slušači. Tijekom studija studenti zdravstva moraju ovladati digitalnim vještinama kako bi bili što učinkovitiji u svojem poslu. Stoga je potrebno da nastavni proces bude moderan i kvalitetan. Cilj istraživanja: Kroz anketiranje ispitati zadovoljstvo metodama poučavanja, poznavanje suvremenih alata u nastavi te stupanj motivacije kod studenata/učenika te zdravstvenih djelatnika sa završenim formalnim školovanjem. Metode: Provedena je anonimna anketa na uzorku od 531 ispitanika. Za potrebe istraživanja konstruiran je strukturirani upitnik koji je izrađen na principu petostupanjske Likertove ljestvice. Anketa se sastoji od sociodemografskih podataka (spol, dob, mjesto školovanja, nivo obrazovanja), tvrdnji za procjenu motivacije te tvrdnji za procjenu nastavnih metoda. Kod 23 ispitanika u tijeku je srednjoškolsko obrazovanje (4,33%), 179 ispitanika završilo je srednju zdravstvenu školu (33,71%), 106 je studenata zdravstva (19,96%), 170 prvostupnici (32,02%), 18 ih je diplomiralo (3,39%), a 35 magistriralo (6,59%). Rezultati: Istraživanje je pokazalo da su tvrdnje o motivaciji za prisustvovanje predavanju ocijenjene prosječnom ocjenom od 3,39 (zanimljiva i poticajna predavanja, odlazim jer moram i sl.). Tvrdnje koje se odnose na poznavanje suvremenih nastavnih metoda i njihovu primjenu u nastavi ocijenjene su prosjekom od 1,49 (Schoology, Kahoot i dr.). Zaključak: Iz provedene ankete može se zaključiti da postoji potreba za modernizacijom i prilagođavanjem predavačkih metoda novim generacijama studenata. Uvođenjem suvremenih nastavnih alata nastava će postati modernija i kreativnija, čime će se povećati motivacija za učenje i sudjelovanje u nastavnom procesu. - Education of healthcare workers through formal teaching is often conducted “ex catedra”, where the lecturer conveys the knowledge while students are the listeners. During the course, healthcare students have to overmaster digital skills in order to be as efficient as possible in doing their work. Due to that, the teaching process needs to be modern and of good quality. Aim of the research: Contentment with the teaching methods, proficiency with the contemporary tools in teaching process, as well as the level of motivation of students and healthcare workers with completed formal education, have to be examined through surveys. Methods: An anonymous survey was conducted among 531 examinees. For the purpose of the research, structured questionnaire was constituted. It was created according to the principle of the 5-point Likert scale. The survey consists of social-demographic dates (gender, age, place of education, level of education), statements for estimating the motivation, as well as statements for evaluating teaching process. 23 examinees are still in the process of high school education (4,33%), 179 examinees completed medical high school (33,71%), 106 examinees are students who still attend faculty of medicine (19,96%), 170 examinees are bachelors (32,02%), 18 examinees graduated (3,39%) and 35 examinees won a master’s degree (6,59%). Results: The research has shown that claims about motivation regarding lecture attendance have been graded with an average mark 3,39 (interesting and encouraging lectures, I attend because I have to etc.) Claims concerning proficiency with the contemporary tools and their appliance in the process of teaching have been graded with the average of 1,49 (Schoology, Kahoot and others.) Conclusion: From the conducted survey, there could be drown a conclusion that there exists the necessity for modernisation and adjustment of the teaching methods concerning new generations of students.

ŠTEKL, Rudi
Online studiranje kao uspješna metoda obrazovanja demografski starijih skupina na primjeru odabrane institucije [Elektronička građa] / Rudi Štekl. - Graf. prikazi.
Bibliografija: 6 jed. - Sažetak ; Summary. - Online studiranje ili učenje na daljinu novi je model obrazovanja u Republici Hrvatskoj koji dobiva sve veću prihvaćenost kod svih dobnih skupina polaznika. Ovakav model posebno kod visokog obrazovanja dobiva sve veću zastupljenost kod visokoobrazovnih institucija u Hrvatskoj. Online studiranje relativna je novina u sustavu obrazovanja Republike Hrvatske koja se susreće s raznom problematikom, a jedna od osnovnih je stigmatizacija koju trenutno ovaj model prolazi, percepcija javnosti da je online studiranje zapravo „online tečaj“. Jednako tako navedeni novi i inovativan model nudi široki spektar prilagodbe i individualiziranja svakom pojedinom polazniku studentu što je novina u sustavu obrazovanja. Ovakav su model zapadnoeuropske visokoobrazovne institucije davno implementirale u svoje sustave. Primarni cilj ovoga rada je prikazati socio-demografsku skupinu polaznika online studija jedne visokoobrazovne institucije u jednoj regiji Hrvatske. Cilj ovoga rada je i ujedno objasniti online studiranje ili učenje na daljinu u Republici Hrvatskoj, prikazati koji su izazovi, nedostaci i mogućnosti s kojima se susreću studenti koji pohađaju online studij i institucije koje ih imaju u ponudi. Kroz rad je prikazan konkretan primjer demografske skupine studenata u jednoj regiji Republike Hrvatske na primjeru jedne visokoobrazovne institucije te razlozi zašto su odabrali baš ovaj model. Uloga i značaj ovakvih inovativnih modela obrazovanja sve je više izražena upravo u vidu potreba tržišta odnosno osoba koje ih pohađaju. U konačnici polaznici su ti koji određuju perspektivu i budućnost ovakvih novih modela obrazovanja. - Online study or distance learning is a new model of education in the Republic of Croatia that is gaining increasing acceptance among all age groups of students. This model is especially becoming prominent and represented in higher education institutions in Croatia. As a relative novelty in the education system of the Republic of Croatia, online study encounters various issues, and one of the basic stigmatization that this model is currently facing, is the common public perception that online study is actually an “online course.” Another novelty in the education system is the wide spectrum of required adaptation and individualization of each student. This model of Western European higher education institutions has long been implemented in their systems. The primary goal of this paper is to show the socio-demographic group of online students in a region of Croatia. The paper also aims to explain online or distance learning in the Republic of Croatia, to show the challenges, shortcomings and opportunities faced by students attending online studies and institutions that offer them. The paper presents a concrete example of a demographic group of students in one region of the Republic of Croatia through observation of a higher education institution and the reasons why they chose this model. The role and importance of such innovative models of education is increasingly expressed precisely in the form of the needs of the market or the people who attend them. Ultimately, it is the students who determine the perspective and future of such new models of education.

Perceptions of administrative staff on career advancement realities at a South African university [Elektronička građa] / Barney Erasmus.
Bibliografija: 51 jed. - Summary ; Sažetak. - The necessary training and development to equip staff to fill critical positions accounts for a substantial percentage of the annual budget of universities. This article reports on perceptions on career advancement among administrative staff at a South African university. This study extends the existing body of knowledge concerning the barriers to career advancement at universities. Qualitative research approach was adopted, with the sample consisting of 14 middle-ranking members of the administrative staff, who had been identified for possible senior management posts. Empirical results identified barriers which limit career advancement, namely that there has been a shift from a collegial to a managerial governance model; and that a perceived silo mentality has led to increasing politicisation of the workplace. Furthermore, a lack of managerial skill means that training opportunities and departmental goals are not well communicated to staff members; and inadequate career guidance, retention strategies and opportunities for promotion are all responsible for reducing prospects of career advancement. However, the participants indicated that they had not lost hope and would continue to perform to the best of their ability and even go beyond what was expected of them. Managers should, however, not lose sight of the possibility that morale and productivity will suffer, if talented employees become dissatisfied, and that future leaders may resign, with a consequent failure to achieve departmental goals. The results of this study may serve as a wake-up call to university management: strategies aimed at the retention of administrative staff and at promotion policies need to be revised because the staff that make up this cohort perform essential university services. - Potrebna obuka i razvoj, koji omogućavaju osoblju popunjavanje kritičnih pozicija, troši značajan postotak godišnjeg sveučilišnog budžeta. U ovom se radu prezentira percepcija razvoja karijere administrativnog osoblja na južnoafričkom sveučilištu, čime se proširuje postojeće znanje o ograničenjima za napredovanje u karijeri na sveučilištima. Korišten je kvalitativni pristup, s uzorkom od 14 administrativnih zaposlenika, koji su identificirani kao kandidati za moguće popunjavanje viših menadžerskih pozicija. Rezultati empirijskog istraživanja utvrdili su ograničenja napredovanja u karijeri, koja su se odnosili na prelazak s kolegijalnog na menadžerski orijentiran model upravljan, kao i povećanu organizacijsku politiku, uslijed percipiranog mentaliteta zatvaranja u vlastiti odjel. Nadalje, nedostatak menadžerskih vještina znači da se mogućnosti za obuku i odjelni ciljevi ne komuniciraju dobro članovima osoblja, dok su neodgovarajuće savjetovanje o razvoju karijera, strategije zadržavanja zaposlenika i mogućnosti za unapređenje na više pozicije razlozi smanjenja mogućnosti napredovanja u karijeri. Bez obzira na navedeno, sudionici istraživanja su ukazali da ne gube nadu te da će nastaviti, u skladu sa svim svojim mogućnostima, obavljati svoj posao te, čak, pokušati premašiti ono što se od njih očekuje. Menadžeri, pak, ne trebaju smetnuti s uma činjenicu da će moral i produktivnost patiti, ukoliko su talentirani zaposlenici nezadovoljni, što može dovesti i do odustajanja budućih vođa, s posljedicama za postizanje odjelnih ciljeva. Rezultati ovog rada mogu poslužiti kao oblik „otvaranja očiju“ sveučilišnim upravama, kako je potrebno revidirati strategije za zadržavanje administrativnog osoblja i politike napredovanja, s obzirom da oni pružaju ključne usluge na sveučilištu.

Risk management in the higher education quality insurance system [Elektronička građa] / Živko Kondić, Željko Knok, Veljko Kondić, Sanja Brekalo. - Graf. prikazi.
Bibliografija: 17 jed. - Summary. - Due to the factors that affect the results of work on a daily basis, higher education institutions, through their quality assurance systems, or their planning, must assess risks. In doing so, they must take into account all issues of the internal and external context as well as the needs and expectations of all stakeholders in higher education. The paper explains in an appropriate way the concept of risk as well as all the elements that determine it and their classification in the field of higher education. Subsequently, a possible approach to risk management is discussed, with an emphasis on clarifying the principles and the risk management process itself. Finally, the basics of practical application in risk identification, analysis, evaluation and treatment are outlined.

Strategy for development and assessment of critical thinking in undergraduate management and leadership education [Elektronička građa] / Alina Zapalska, Ben Wroblewski, Peter Imbriale, Parish Kaleiwahea, Joshua Schwartz. - Graf. prikazi.
Bibliografija: 25 jed. - Summary ; Sažetak. - This paper illustrates a strategy for advancing and assessing critical thinking skills in an undergraduate business program. The 21st Century Bloom’s taxonomy is implemented to support the continuous and progressive development of critical thinking skills across the curriculum. The success of this strategy for critical thinking development is based on the effectiveness of sequentially designed instruction with a continuous process of assessing critical thinking skills development throughout all four years of the undergraduate program. This strategy can be implemented with minimal effort within any undergraduate program that is responsible for educating future entrepreneurs. - Ovaj rad ilustrira strategiju za unapređivanje i procjenu sposobnosti kritičkog razmišljanja u preddiplomskom poslovnom programu. Bloomova taksonomija 21. stoljeća provodi se kao potpora stalnom i progresivnom razvoju vještina kritičkog mišljenja kroz nastavni plan i program. Uspjeh ove strategije za razvoj kritičkog mišljenja temelji se na učinkovitosti sekvencijalno osmišljene nastave uz kontinuirani proces procjene razvoja sposobnosti kritičkog mišljenja tijekom sve četiri godine preddiplomskog programa. Ova se strategija može provesti uz minimalan napor u okviru bilo kojeg preddiplomskog programa koji je odgovoran za obrazovanje budućih poduzetnika.

Sveučilišna nastava kao odraz različitih teorijskih pristupa [Elektronička građa] = University teaching as a reflection of different theoretical approaches / Valerija Podgorelec, Dalila Stunić, Štefica Mikšić. - Graf. prikazi.
Bibliografija: 14 jed. - Sažetak ; Abstract. - Uvod: Kombinacijom teorijskih pristupa u nastavi povećava se motivacija stu- denata i kvaliteta odgojno-obrazovnog procesa. Cilj ovog rada bio je ispitati prisutnost teorijskih pristupa s njihovim odrazom na kvalitetu sveučilišne nastave, kreativnost, samoaktualizaciju, usvajanje znanja, vještina i sposobnosti te pri- sutnost (ne)ugodne klime. Metoda: Uporabom anonimnog anketnog upitnika provedeno je istraživanje najčešćih pristupa u nastavi studenata Učiteljskog studija i Studija sestrinstva u Osijeku te studenata Studija sestrinstva u Čakovcu. Rezultati: Rezultati istraživanja pokazali su da je, bez značajne razlike na obje vrste studija, najviše korišten sociocentristički pristup, kod čak 80 % studena- ta. Na Učiteljskom studiju značajnija je zastupljenost pedocentrističkog pristu- pa (Fisherov egzaktni test, P <0,001), umjetničkog (Fisherov egzaktni test, P = 0,001), emancipacijskog (Fisherov egzaktni test, P = 0,02), kreativnog (Fishe- rov egzaktni test, P <0,001) u odnosu na studente Studija sestrinstva. Značaj- nija je zastupljenost komponenata sustavnog (Mann Whitney U test, P = 0,01) i kreativnog pristupa (Mann Whitney U test, P = 0,004) u odnosu na studente Studija sestrinstva. Individualni oblik rada (Mann Whitney U test, P = 0,02), i aktivnost u paru (Mann Whitney U test, P = 0,04), značajnije je primijenjen na Učiteljskom studiju nego na Studiju sestrinstva. Motivacija i opuštenost značaj- ne su na studiju Sestrinstva (Fisherov egzaktni test, P = 0,005). Sveučilišna na- stava Učiteljskog studija kreativna je za 30 ispitanika (38,5 %), dok je na Studiju sestrinstva nastava pedocentrična (Fisherov egzaktni test, P = 0,003). Zaključak: Studenti Učiteljskog studija imaju više zastupljenih kreativnih pri- stupa u odnosu na Studij sestrinstva. - Introduction: The combination of theoretical approaches to teaching increases the students’ motivation and quality of the educational process. The aim of this paper was to examine the existence of theoretical approaches with their reflection upon the quality of teaching, creativity, self-actualization, the acquisition of knowledge, skills and abilities, and the presence of (un)comfortable climate. Method: Using an anonymous questionnaire, a survey of the most common approaches in teaching was conducted among the students of the Faculty of Teacher Education in Osijek and the Nursing Studies in Osijek and Čakovec. The data was collected using questionnaires. Results: Results show that, without significant differences in both types of studies, 80 % of students report the usage of the sociocentristic approach. At the Faculty of Teacher Education, there was a more significant representation of the pedocentric (Fisher’s Exact test, P <0.001), artistic (Fisher’s Exact test, P = 0.001), emancipatory (Fisher’s Exact test, P = 0.02) and creative approach (Fisher’s Exact test, P <0.001 ) compared to the students of the Nursing Studies. There was a more significant representation of the components of the systematic (Mann Whitney U test, P = 0.01) and creative approach (Mann Whitney U test, P = 0.004) compared to students of the Nursing Studies. The individual form of work (Mann Whitney U test, P = 0.02), and pair work activity (Mann Whitney U test, P = 0.04), were more significantly applied at the Faculty of Teacher Education than at the Nursing Studies. Motivation and relaxation are more significant at the Nursing Studies (Fisher’sExact Test, P = 0.005). The courses at the Faculty of Teacher Education are creative for 30 students (38.5 %), and they are pedocentric and more significantly useful at the Nursing Studies (Fisher’sExact Test, P = 0.003).

Zadovoljstvo studenata Tehničkog veleučilišta u Zagrebu provođenjem online nastave [Elektronička građa] / Lucija Bačić, Marija Krstinić. - Graf. prikazi.
Bibliografija: 5 jed. - Sažetak ; Summary. - Epidemija uzrokovana virusom Covid-19 aktualizirala je potrebu za otkrivanjem različitih metoda kao i procjenom uspješnosti poučavanja „na daljinu“. Nastavnici i studenti diljem svijeta su se suočili s možda i najvećim izazovom dosad, u kratkom vremenu se prilagoditi dostupnim platformama i jednako tako prihvatiti kako prednosti tako i mane virtualne nastave. Ova epidemija je zapravo i proširila jaz između onih koji mogu pristupiti mogućnostima digitalnog učenja i onih koji su isključeni jer se nisu svi jednako uspješno prilagodili. Isto tako se mora naglasiti da dobro iskustvo online učenja nije nužno vezano uz tehnologiju koju izabiremo, već uz način na koji se nastavnici i studenti posvete tom podučavanju, pogotovo kada je riječ o učenju stranog jezika. U ovom radu provedeno je istraživanje na uzorku od 120 redovnih i izvanrednih studenata 2. godine Strojarskog odjela Tehničkog veleučilišta u Zagrebu, u travnju i svibnju 2020. godine. Ciljevi istraživanja su pokazati stupanj zadovoljstva, odnosno nezadovoljstva studenata Tehničkog veleučilišta kao i utvrditi stupanj težine savladavanja stranog jezika online nastavom. Istraživanje je provedeno anketnim upitnikom na temelju kojeg će se izračunom relativnih frekvencija utvrditi navedeni ciljevi. - The Covid-19 virus epidemic has highlighted the need to discover different methods as well as assess the success of distance learning. Teachers and students around the world have faced perhaps the greatest challenge so far, adapting to the available platforms in a short time and equally embracing both the advantages and disadvantages of virtual teaching. This epidemic has actually widened the gap between those who can access digital learning opportunities and those who are excluded because not everyone has adapted to the situation equally successfully. We must also emphasize that a good online learning experience is not necessarily related to the technology we choose, but to the way teachers and students dedicate themselves to that form of teaching and learning, especially when it comes to learning a foreign language. In this paper, a research was conducted on a sample of 120 full-time and part-time students of the 2nd year of the Mechanical Engineering Department at the Zagreb University of Applied Sciences, in April and May 2020. The objectives of the research are to show the degree of satisfaction or dissatisfaction of the students at the Zagreb University of Applied Sciences as well as to determine the degree of difficulty in mastering a foreign language by online teaching. The research was conducted with a survey questionnaire on the basis of which the calculation of relative frequencies will determine the stated goals.

Biodegradation of tannery effluent and its impact on seed germination of Oryza sativa [Elektronička građa] / Jenny Sivakumar, Malliga Perumal. - Ilustr., graf. prikazi.
Bibliografija: 15 jed. - Summary. - Environmental pollution, especially of water bodies, is one of the major problems and it is increased day by day. The contamination of environment with various toxic metals is a serious threat for ecosystem and human health. Industrial effluents may contain toxic metals, harmful volatile compounds and several organic and inorganic compounds such as chromium, cadmium, mercury, arsenic and lead which are directly or indirectly discharged into the environment without adequate treatment. However, tannery industries are the major source of chromium contamination into the environment. Tanneries are typically characterized as pollution intensive industrial complexes which generate widely varying, high-strength wastewaters. The discharge of these toxic effluents has been a major loss from the ecological, social and economic perspective. There are many conventional physiochemical methods available for the removal of heavy metals from the tannery effluents that are highly expensive and require skilled techniques. However, microbial reduction of toxic chromium to non-toxic chromium by chromium resistance microorganism is the most pragmatic approach that offers an economical as well as eco-friendly process. Hence, this study examines the biodegradation of tannery effluent and its impacts on the germination of Oryza sativa seeds.

Environmental problems of Manipur [Elektronička građa] / Arambam Sophia, Mayanglambam Sarda Devi. - Graf. prikazi.
Bibliografija: 45 jed. - Summary. - The issue of environment versus human activity has become one of the most common global topics. Global warming, greenhouse effect, air pollution, land and water pollution are all results of human activity. Human behaviour lies at the root of both conservation and environmental damage. The rapid growth of population and economic development are some of the greatest threats to the environment through the expansion and intensification of agriculture, uncontrolled growth of urbanization and industrialization, and the destruction of natural habitats. The paper seeks to study the unique features of Manipur, a pristine land situated in the North-East corner of India which is noted for its rich biodiversity, abundance of medicinal plants with various healing properties and yet it is facing the threat of environmental degradation and pollution. It is mainly rapid population growth, unplanned urbanization in urban areas, lack of awareness about environmental issues, poverty and Jhuming cultivation practices in the hills that have led to environmental damage, with its concomitant effects on human development, for it is ultimately the people of the state who have to suffer the effects of environmental damage. The paper gives a broad picture of the abundant green resources and unique fauna of Manipur and the environmental problems that threaten its biodiversity.

7. hrvatski simpozij o kemiji i tehnologiji makromolekula, Zagreb, 27.9.2019. - Bibliografija: 44 jed. - Sažetak ; Summary. - Plastika se zbog svoje široke uporabe može naći u svim dijelovima okoliša, gdje štetno utječe na različite sastavnice okoliša, a toksični spojevi koje adsorbira prenose se kroz hranidbene lance te s vremenom dolaze do čovjeka. Odabrana istraživanja u ovom radu usredotočena su na karakterizaciju i kvantifikaciju mikroplastike pronađene u Jadranskom moru kao i na toksičnost mikroplastike. Istraživanja su pokazala da je najviše mikroplastike detektirano u području Sjevernog Jadrana. Provedena ispitivanja ekotoksičnosti mikroplastike primjenom testa s algama ukazuju na to da mikroplastika uzrokuje smanjenje brzine rasta i kretanja algi, obavljanje fotosinteze, fizičke deformacije te dolazi do smanjenja plodnosti i promjena u metaboličkim ciklusima. - The widespread use of plastics has led to the accumulation of plastics in all parts of the environment where it adversely affects the ecosystem. Plastic pollution has the biggest impact on the marine ecosystems which assimilate about 12.7 million tons of plastic yearly. Because of incomplete degradation, plastic in marine environment is accumulated in the form of large clusters and microplastic. Microplastic has a harmful impact on marine organisms due to the accumulation of toxic compounds adsorbed on its particles, which could be passed through the food chain and eventually to humans. Certain researches discussed in this paper are focused on the characterization and quantification of microplastic found in the Adriatic Sea.

Organochlorine contamination in sediments collected from a rural-, urban- and industrial-impacted aquatic system (Danube, Serbia) [Elektronička građa] / Maja Brborić, Jelena Radonić, Mirjana Vojinović Miloradov, Sabolč Pap, Maja Turk Sekulić. - Graf. prikazi.
Bibliografija: 11 jed. - Summary. - The spatial distribution of various organochlorinated compounds (PCBs and ОCPs (DDTs, HCB, and HCHs)) were investigated in sediments of Serbia's stretch of the Danube River. The obtained concentrations appeared to be relatively low in comparison with other river sediments worldwide. The results demonstrated a wide range of concentrations (µg/kg dry weight) with the following decreasing order: Σ6DDTs (0.70 - 16.65) >Σ 7PCBs (0.25 - 3.54) >Σ 5HCH (0.04 - 2.28) >HCB (0.06 - 0.62), with a dominance of o,p’ -DDT. Relatively higher ΣDDT concentrations and high DDT/DDE + DDD ratios in two sampling locations near the industrial cities indicates a current DDT usage, probably linked to public health concerns. Compositional analyses indicated that hexa- and hepta-PCBs were dominant for PCBs. Our results indicated that the contamination with PCBs came from nonpoint deposition, such as atmospheric contribution and surface runoff, for lightly chlorinated congeners and point source deposition, such as the industrial sources along river flow, for highly chlorinated congeners, whereas OCPs originate mainly from old residues and new usage of pesticides in agriculture and aquaculture. These results contribute to the sparse regional database for organochlorinated compounds in the Danube basin.

A note on the exponential Diophantine equation (A^2n)^x+(B^2n)^y=((A^2+B^2)n)^z [Elektronička građa] / Maohua Le, Gökhan Soydan.
Bibliografske bilješke na kraju teksta. - Abstract. - Let A, B be positive integers such that min{A,B}>1, gcd(A,B) = 1 and 2|B. In this paper, using an upper bound for solutions of ternary purely exponential Diophantine equations due to R. Scott and R. Styer, we prove that, for any positive integer n, if A >B3/8, then the equation (A2 n)x + (B2 n)y = ((A2 + B2)n)z has no positive integer solutions (x,y,z) with x >z >y; if B>A3/6, then it has no solutions (x,y,z) with y>z>x. Thus, combining the above conclusion with some existing results, we can deduce that, for any positive integer n, if B ≡ 2 (mod 4) and A >B3/8, then this equation has only the positive integer solution (x,y,z)=(1,1,1).

MANGER, Robert
An algebraic framework for multi-objective and robust variants of path problems [Elektronička građa] / Robert Manger. - Ilustr.
Bibliografske bilješke na kraju teksta. - Abstract. - It is well known that various types of path problems in graphs can be treated together within a common algebraic framework. Thereby each type is characterized by a different ``path algebra", i.e., a different instance of the same abstract algebraic structure. This paper demonstrates that the common algebraic framework, although originally intended for conventional problem variants, can be extended to cover multi-objective and robust variants. Thus the paper is mainly concerned with constructing and justifying new path algebras that correspond to such more complex problem varieties. A consequence of the obtained algebraic formulation is that multi-objective or robust problem instances can be solved by well-known general algorithms designed to work over an arbitrary path algebra. The solutions obtained in this way comprise all paths that are efficient in the Pareto sense. The efficient paths are by default described only implicitly, as vectors of objective-function values. Still, it is shown in the paper that, with slightly extended versions of the involved algebras, the same paths can also be identified explicitly. Also, for robust problem instances it is possible to select only one ``robustly optimal" path according to a generalized min-max or min-max regret criterion.

Approximate inverse limits and (m,n)-dimensions [Elektronička građa] / Matthew Lynam, Leonard R. Rubin.
Bibliografske bilješke na kraju teksta. - Abstract. - In 2012, V. Fedorchuk, using m-pairs and n-partitions, introduced the notion of the (m,n)-dimension of a space. It generalizes covering dimension. Here we are going to look at this concept in the setting of approximate inverse systems of compact metric spaces. We give a characterization of (m,n)-dim X, where X is the limit of an approximate inverse system, strictly in terms of the given system.

Centers of subgroups of big mapping class groups and the Tits alternative [Elektronička građa] / Justin Lanier, Marissa Loving.
Bibliografske bilješke na kraju teksta. - Abstract. - In this note we show that many subgroups of mapping class groups of infinite-type surfaces without boundary have trivial centers, including all normal subgroups. Using similar techniques, we show that every nontrivial normal subgroup of a big mapping class group contains a nonabelian free group. In contrast, we show that no big mapping class group satisfies the strong Tits alternative enjoyed by finite-type mapping class groups. We also give examples of big mapping class groups that fail to satisfy even the classical Tits alternative; consequently, these examples are not linear.

Extension of the functional independence of the Riemann zeta-function [Elektronička građa] / Antanas Laurinčikas.

The problem goes back to Hilbert who obtained the algebraic-differential independence of ζ(s). In the paper, the functional independence of compositions F(ζ(s)) for some classes of operators F in the space of analytic functions is proved. For example, as a particular case, the functional independence of the function cosζ(s) follows.

High rank elliptic curves induced by rational Diophantine triples [Elektronička građa] / Andrej Dujella, Juan Carlos Peral.
Bibliografske bilješke na kraju teksta. - Abstract. - A rational Diophantine triple is a set of three nonzero rational a,b,c with the property that ab+1, ac+1, bc+1 are perfect squares. We say that the elliptic curve y2 = (ax+1)(bx+1)(cx+1) is induced by the triple {a,b,c}. In this paper, we describe a new method for construction of elliptic curves over ℚ with reasonably high rank based on a parametrization of rational Diophantine triples. In particular, we construct an elliptic curve induced by a rational Diophantine triple with rank equal to 12, and an infinite family of such curves with rank ≥ 7, which are both the current records for that kind of curves.

The minimally displaced set of an irreducible automorphism is locally finite [Elektronička građa] / Stefano Francaviglia, Armando Martino, Dionysios Syrigos.
Bibliografske bilješke na kraju teksta. - Abstract. - We prove that the minimally displaced set of a relatively irreducible automorphism of a free splitting, situated in a deformation space, is uniformly locally finite. The minimally displaced set coincides with the train track points for an irreducible automorphism. We develop the theory in a general setting of deformation spaces of free products, having in mind the study of the action of reducible automorphisms of a free group on the simplicial bordification of Outer Space. For instance, a reducible automorphism will have invariant free factors, act on the corresponding stratum of the bordification, and in that deformation space it may be irreducible (sometimes this is referred as relative irreducibility).

We separately deal with strict and strong 1-dimensional topological quantum field theories. The strict one is regarded as a symmetric monoidal functor between the category of 1-cobordisms and the category of matrices, and the strong one is a symmetric monoidal functor between the category of 1-cobordisms and the category of finite dimensional vector spaces. It has been proved that both strict and strong 1-dimensional topological quantum field theories are faithful.

Partial qualitative analysis of planar A_Q-Riccati equations [Elektronička građa] / Borut Zalar, Brigita Ferčec, Yilei Tang, Matej Mencinger.
Bibliografske bilješke na kraju teksta. - Abstract. - If we view the field of complex numbers as a 2-dimensional commutative real algebra, we can consider the differential equation z′=az2+bz+c as a particular case of A− Riccati equations z′=a⋅(z⋅z)+b⋅z+c where A=(Rn,⋅) is a commutative, possibly nonassociative algebra, a,b,c∈A and z:I→A is defined on some nontrivial real interval. In the case A=C, the nature of (at most two) critical points can be described using purely algebraic conditions involving involution ∗ of C. In the present paper we study the critical points of L(π)− Riccati equations, where L(π) is the limit case of the so-called family of planar Lyapunov algebras, which characterize 2-dimensional homogeneous systems of quadratic ODEs with stable origin. The number of possible critical points is 1, 3 or ∞, depending on coefficients. The nature of critical points is also completely described. Finally, simultaneous stability of the origin is considered for homogeneous quadratic part corresponding to algebras L(θ).

The characterization of this concept will be also given by means of the associated totally symmetric quasigroup. We will introduce the concept of associated and corresponding points in a cubic structure, and discuss the number of mutually different corresponding points. The properties of the introduced geometric concepts will be investigated in a general cubic structure.

Accuracy analysis of point velocities determined by different software packages and GNSS measurement processing methods [Elektronička građa] / Margareta Premužić, Almin Đapo, Željko Bačić, Boško Pribičević. - Graf. prikazi.
Bibliografija: 24 jed. - Abstract. - The paper analyzes the geodynamic network of the City of Zagreb for periodic campaigns carried out from 2006 to 2009 which were processed by different software packages. The first computations and processing results were obtained by using the scientific software Gamit/Globk and indicate the ongoing tectonic activity of the area. In this paper, all calculations were performed by using the scientific software Bernese. Processing strategies and applied error models in the Gamit and Bernese solution are analyzed. The results of the previous analyses show the need to perform GNSS measurements at intervals of up to one year, which is necessary for understanding the mechanism of the structural frame of the wider Zagreb area. The research and analysis performed in this paper indicate certain uncertainties in determining the velocities from periodic one-year GNSS measurements. When periodic GNSS observations are analyzed at time intervals shorter than 2.5 years, annual signals can cause significant errors in determining point velocities. The accuracy of determining velocities between annual time intervals depends on a number of factors: noise level in GNSS measurements, measurement sessions quantity and applied computation strategies. Previously, the time series analysis of observations was a key procedure in the context of geodynamic and geokinematic research and the FODITS algorithm was used for the analysis. A noise analysis on the daily time series of coordinates was performed for the purpose of understanding all influences on geodynamic points. Moreover, a correlation between the time series of observations was determined in order to estimate the final velocity uncertainty error.

"Modeli molekula" Drage Grdenića i početci strukturne kemije u Hrvatskoj [Elektronička građa] / Nenad Raos. - Ilustr., graf. prikazi.
Bilješke uz tekst. - Bibliografija: 39 jed. - Sažetak ; Summary. - Početak strukturne kemije u Hrvatskoj može se smjestiti u 1948. godinu kada se Drago Grdenić (1919. – 2018.) vraća sa stručnog usavršavanja na Moskovskom sveučilištu (kod Nesmejanova i Kitajgorodskija) u Zagreb i gdje osniva 1952. Zavod za opću i anorgansku kemiju Prirodoslovno-matematičkog fakulteta. Pedesetih godina uspostavlja se suradnja i s Dorothy C. Hodgkin (Sveučilište u Cambridgeu). Zavod se poglavito bavi spojevima žive, potom molibdena, vanadija te organskim spojevima, posebice azitromicinom i njegovim derivatima. U radu je posebno obrađena Grdenićeva knjiga "Modeli molekula" (1950.), koja je formalno bila napisana kao priručnik za upotrebu kalotnih (Stuartovih) modela tvrtke Učila, no na svoje 142 stranice dala je pregled atomske teorije, stereokemije i strukturne kemije, čime je otvorila put modernoj kemiji u hrvatske škole. - The beginning of structural chemistry in Croatia can be placed in the year of 1948 when Drago Grdenić (1919–2018) finished his postgraduate study at Moscow University (visiting Nesmeyanov and Kitaigorsky) and in 1952 founded the Department of General and Inorganic Chemistry at the Faculty of Science, University of Zagreb. The research field of Professor Grdenić and his Department was primarily the structural chemistry of mercury compounds, and that of coordination compounds of molybdenum and vanadium, as well as of organic compounds, including macrolide antibiotic azithromycin and its derivatives (in cooperation with PLIVA pharmaceutical company). Special emphasis is given to Grdenić’s book "Modeli molekula" (Models of Molecules), published in 1950, that was initially written as a handbook for the use of Stuart models, produced by the Zagreb company Učila, but turned out to be an extensive, but popular introduction into atomic theory, stereochemistry and structural chemistry. Thus, the book paved the way of modern chemistry to Croatian schools.

A wide variety of headspace compounds from different natural sources has been identified: lower aliphatic compounds (e.g., C5- and C6-compounds), aromatic compounds, monoterpenes (e.g., linalool derivatives (oxides, anhydro-oxides, epoxides), hotrienol), sesquiterpenes (e.g., eudesmol isomers, hydrocarbons), and C9- and C13-norisoprenoids (e.g., 3,4-dihydro-3-oxoedulan, 4-oxoisophorone, trans-β-damascenone). These compounds are important phytochemicals as flavour/fragrance compounds, chemical markers of the botanical origin or others (e.g., allelochemicals, pheromones, or acaricide residue). - Ukratko su prikazani odabrani rezultati primjene mikroekstrakcije vršnih para na čvrstoj fazi kao preparativnog pristupa plinskoj kromatografiji – spektrometriji masa (HS-SPME/GC-MS) za istraživanje prirodnih spojeva, koje je provedeno na Kemijsko-tehnološkom fakultetu Sveučilištu u Splitu.

C5- i C6-spojevi), aromatski spojevi, monoterpeni (npr. derivati linaloola (oksidi, anhidro-oksidi, epoksidi), hotrienol), seskviterpeni (npr. eudezmol izomeri, ugljikovodici) te C9- i C13-norizoprenoidi (npr. 3,4-dihidro-3-oksoedulan, 4-oksoisoforon, trans-β-damascenon). Ti su spojevi važne fitokemikalije kao spojevi aroma/mirisa, kemijski marker botaničkog podrijetla ili drugo (npr. aleokemikalije, feromoni ili ostatci akaricida).

Assessment and evaluation of ambient PM2.5 in relation to its health effects in mineral-based coal-fired areas [Elektronička građa] / Shamsh Pervez, Rakesh Kumar Sahu, Mamta Tripathi, Shahina Bano, Jeevan Lal Matawle, Suresh Tiwari, Manas Kanti Deb, Yasmeen Fatima Pervez. - Graf. prikazi.
Bibliografija: str. 81-86. - Summary ; Sažetak. - Atmospheric PM2.5 pollution, has shown potential impact on the human health in general, thus it requires to look into the chemical characteristics of PM2.5 masses for designing effective policies to reduce health risks amongst public under exposure. The study carried out, here, has presented the ambient PM2.5 concentrations, concentrations of chemical components and associated health risks over rural and urban environments in the area of mineral based coal-fired industrial areas of central India for a period of one year (2015–16). Overall 260 PM2.5 samples, collected from rural, urban and industrial sites, were analyzed for various elements Al, As, Ca, Hg, Cr, Co, Cu, Fe, Mn, K, Cd, Mo, Ni, Pb, Se, Sb, Na, Mg, K, V and Zn, ions such as Na+, Mg2+, K+, Ca2+, F–, Cl–, NH4+, NO3–, SO42– and carbonaceous matter. The annual average PM2.5 mass concentrations were found to be ~2 to ~6 folds higher than the annual National Ambient Air Quality standard (40 µg m–3). Further this study also evaluates, carcinogenic and non-carcinogenic health risks associated with ambient PM2.5 exposures (via ingestion, inhalation and dermal). The elemental species that have shown non-carcinogenic risks for both children and adults of all three sites are: Co, Mn, Ni (rural), As, Cd, Cr, Mn, Ni, V (urban and industrial sites). Similarly, the excess carcinogenic risks, in total, from Cd, Co, Cr, Ni, Pb was found to be higher than acceptable limits (10–6 to 10–4). - Onečišćenje atmosfere lebdećim česticama (PM2.5) pokazalo je potencijalni utjecaj na zdravlje ljudi općenito. Stoga je potrebno sagledati kemijska svojstva čestica PM2.5 kako bi se postiglo učinkovito smanjenje zdravstvenih rizika izložene populacije. U ovome radu prikazuju se rezultati studije koncentracija PM2.5 i koncentracija kemijskih sastojaka u lebdećim česticama za jednogodišnje razdoblje (2015.–2016.) koji su povezani sa zdravstvenim rizicima u ruralnim i urbanim sredinama u industrijskim područjima u središnjoj Indiji u kojima se koristi mineralni ugljen kao pogonsko industrijsko gorivo. Ukupno je analizirano 260 uzoraka PM2.5 s ruralnih, urbanih i industrijskih lokacija za različite elemente: Al, As, Ca, Hg, Cr, Co, Cu, Fe, Mn, K, Cd, Mo, Ni, Pb, Se , B, Na, Mg, K, V i Zn, ione poput Na+, Mg2+, K+, Ca2+, F–, Cl–, NH4+, NO3–, SO42– i spojeve ugljika. Utvrđeno je da su prosječne godišnje masene koncentracije PM2.5 od ~2 do ~6 puta više od dopuštenih godišnjih vrijednosti prema indijskom Nacionalnom standardu kvalitete zraka (40 µgm–3). Nadalje, ova studija također ocjenjuje kancerogene i nekancerogene rizike za zdravlje povezane s izloženošću česticama PM2.5 u okolišu (putem gutanja, udisanja i dodira s kožom). Elementi koji su pokazali nekancerogene rizike i za djecu i za odrasle na sve tri lokacije su: Co, Mn, Ni (ruralno područje), As, Cd, Cr, Mn, Ni i V (urbano i industrijsko područje). Slično, utvrđen je povećan kancerogeni rizik za Cd, Co, Cr, Ni i Pb, koji je veći od prihvatljivih granica (10–6 do 10–4).

Bibliografija: 51 jed. - Sažetak ; Summary. - Istraživanja predstavljena u ovom preglednom radu doprinose poznavanju isparljivih organskih spojeva iz morskih organizama, posebno iz makroalgi Jadranskog mora. Za izolaciju isparljivih spojeva iz svježih i/ili na zraku osušenih uzoraka primijenjene su komplementarne metode: mikroekstrakcija vršnih para na čvrstoj fazi (HS-SPME) i/ili hidrodestilacija (HD). Dobiveni izolati analizirani su vezanim sustavom plinske kromatografije-spektrometrije masa (GC-MS). U vršnim parama i isparljivim uljima makroalgi Halopteris filicina, Flabellia petiolata, Dictyota dichotoma, Taonia atomaria, Padina pavonica, Codium bursa i morskoj cvjetnici Posidonia oceanica pronađeno je mnoštvo različitih spojeva, uglavnom seskviterpena, diterpena i alifatskih spojeva. Alifatski spojevi male molekulske mase, poput dimetil-sulfida (DMS), tribrommetana, 1-jodpentana, 3-metilbut-2-enala, heksanala i pent-1-en-3-ona, nađeni su u kemijskim profilima vršnih para. Također su identificirani i alifatski C8- i C11-spojevi (npr. oktan-l-ol, oktanal, okt-1-en-3-ol, 6-metilhept-5-en-2-on, fukoseraten i diktioptereni). Zajedno s višim acikličkim ugljikovodicima, također pronađenim u vršnim parama (npr. heptadekan), u ispitivanim isparljivim uljima identificirani su i viši alifatski alkoholi (npr. (Z)-oktadec-9-en-1-ol, heksadekan-1-ol, (Z,Z)-oktadeka-3,13-dien-1-ol) i esteri (npr. diizooktil-ftalat, dibutil-ftalat). Fenilpropanski derivati (npr. benzaldehid, benzil-alkohol) i C13-norizporenoidi (npr. α-jonon i β-jonon) također su pronađeni u isparljivim profilima, kao i mnoštvo seskviterpena (npr. germakren D, biciklogermakren, δ-kadinen, epizonaren, epibicikloseskvifelandren, β-kubeben, gleenol, (E)-β-farnezen). Isparljivi organski spojevi identificirani u morskim algama mogu poslužiti u kemotaksonomskim istraživanjima. - Studies presented in this review contribute to the knowledge of volatile organic compounds (VOCs) from marine organisms, especially macrolgae from the Adriatic Sea. Complementary methods were used for the isolation of VOCs from fresh and/or air-dried samples: headspace solid-phase microextraction (HS-SPME) and/or hydrodistillation (HD). The isolates were analysed by gas chromatography and mass spectrometry (GC-MS). A variety of different volatile compounds, mainly sesquiterpenes, diterpenes and aliphatic compounds were found in headspace and volatile oils of macroalgae Halopteris filicina, Flabellia petiolata, Dictyota dichotoma, Taonia atomaria, Padina pavonica, Codium bursa, and one seagrass Posidonia oceanica. Low molecular aliphatic compounds were found in the chemical profiles of headspace, such as dimethyl sulphide (DMS), tribromomethane, 1-iodopentane, 3-methylbut-2-enal, hexanal and pent-1-en-3-one. Aliphatic C8- and C11-compounds (e.g., octan-1-ol, octanal, oct-1-en-3-ol, 6-methylhept-5-en-2-on, fucoserratene and dictyopterenes) were also identified. Along with higher acyclic hydrocarbons, which are also found in headspace (e.g. heptadecane), in the investigated volatile oils higher aliphatics alcohols (e.g., (Z)-oktadec-9-en-1-ol, hexadecan-1-ol, (Z,Z)-oktadeca-3,13-dien-1-ol) and esters (e.g., diisooctyl phthalate, dibutyl phthalate) were found. Phenylpropane derivatives (e.g., benzaldehyde, benzyl alcohol) and C13-norisporenoids (e.g., α-ionone and β-ionone) were also identified in the volatile profiles, as well as an array of sesquiterpenes (e.g., germacrene D, bicyclogermacrene, δ-cadinene, epizonarene, epi-bicyclosesquiphellandrene, β-cubebene, gleenol, (E)-β-farnesene). VOCs, identified in marine algae, could be useful for chemotaxonomic studies.

Comparison of PAH mass concentrations in aerosols of the middle Adriatic coast area and central Croatia [Elektronička građa] / Ivana Jakovljević, Zdravka Sever Štrukil, Gordana Pehnec, Ivan Bešlić, Andrea Milinković, Saranda Bakija Alempijević, Sanja Frka Milosavljević. - Ilustr., graf. prikazi.
Bibliografija: 23 jed. - Summary ; Sažetak. - Polycyclic aromatic hydrocarbons (PAHs) are considered priority pollutants due to their distribution, persistence, bioaccumulation, and adverse effects on human health. The aim of this study was to obtain the first insight into PAHs mass concentrations bound to airborne particulate matter (PM) in the mid Adriatic coast area of Croatia, and compare them with the PAH levels in Croatia’s urban central area. Relatively low values of PAH mass concentrations were measured in the coastal area, compared to the continental urban region of Croatia impacted by increased emissions due to intensive traffic, industry, and residential heating. A high PM10 contribution of four-ring PAHs (Flu and Pyr) at Martinska site indicated that wood burning heating as well as open fire events, including waste incineration, could be important emission sources of PAHs in the mid Adriatic coast region. - Policiklički aromatski ugljikovodici (PAU) zbog rasprostranjenosti, postojanosti, bioakumulacije i štetnih utjecaja na zdravlje ljudi te biljnog i životinjskog svijeta smatraju se prioritetnim onečišćujućim tvarima. Cilj istraživanja je po prvi put dobiti uvid u masene koncentracije specifičnih PAU-a u lebdećim česticama u zraku priobalnog područja srednjeg Jadrana te napraviti usporedbu s razinama PAU-a urbanog područja središnje Hrvatske. Koncentracije PAU-a u priobalnom području bile su relativno niske u odnosu na koncentracije u urbanoj središnjoj Hrvatskoj, gdje se i očekuju njihove povišene emisije uslijed znatno jačeg intenziteta prometa, industrije te izgaranja biomase uslijed loženja u kućanstvima. Veća zastupljenost PAU-a četirima aromatskim prstenovima (Flu i Pyr) u ukupnoj masi PM10 čestica na mjernoj postaji Martinska upućuju na to da izgaranje drvne biomase uslijed grijanja kućanstava te uslijed požara otvorenog tipa mogu biti važan izvor PAU-a na obalnom dijelu srednjeg Jadrana.

Doprinos istraživanju glukozinolata (2005.- 2020.) [Elektronička građa] : strukturna raznolikost, razgradnja i biološki potencijal / Ivica Blažević. - Graf. prikazi.
Bibliografija: 86 jed. - Sažetak ; Summary. - U radu je prikazan doprinos istraživanju glukozinolata u razdoblju 2005. – 2020. koji je ostvaren radom na Kemijsko-tehnološkom fakultetu, Sveučilišta u Splitu. Pregledom sveoubuhvatne dokumentacije utvrđeno je da znatnom broju predloženih struktura nedostaju važne strukturne informacije koje bi osigurala NMR i MS spektroskopija, pa je danas broj glukozinolata još uvijek varijabilan. U najnovijem istraživanju, u rodu Hesperis, identificiran je 4-O-D-apiozilglukomatronalin, čime ukupni broj glukozinolata danas broji između 89 i 136 struktura. U svrhu identificiranja izvora specifičnih glukozinolata koji bi mogli djelovati kao prekursori biološki aktivnih izotiocijanata, istraživan je sadržaj glukozinolata u biljkama. Istraživanja uključuju i razgradnju glukozinolata (enzimska, termička i kemijska) kao i biološku aktivnost (citotoksična, antimikrobna, protuupalna i dr.). - This review paper presents a contribution to the research of glucosinolates over the period 2005–2020, which was obtained during work at the Faculty of Chemical Technology, University of Split. After review of the comprehensive documentation, it was determined that a significant number of proposed structures lack important structural information that would be provided by NMR and MS spectroscopy, and today the number of glucosinolates is still variable. In the recent study of Hesperis genus, 4-O-D-apiosylglucomatronalin was identified, which gives the total number of glucosinolates today ranging from 89 to 136 structures. In order to identify the sources of specific glucosinolates that could act as precursors of biologically active isothiocyanates, the content of glucosinolates in plants was investigated. The study also includes the degradation of glucosinolates (enzymatic, thermal, and chemical), as well as biological activity (cytotoxic, antimicrobial, anti-inflammatory, etc.).

Elaboration and mechanical-electrochemical characterisation of open cell antimonial-lead foams made by the "excess salt replication method" for eventual applications in lead-acid batteries manufacturing [Elektronička građa] / Amel Hind Hassein-Bey, Abd-Elmouneïm Belhadj, Adinel Gavrus, Salam Abudura. - Ilustr., graf. prikazi.
Bibliografija: 38 jed. - Summary ; Sažetak. - In this study, open cell 25 % antimony-lead alloy foams are fabricated for possible use to lighten thick plates of lead-acid batteries. A new inexpensive and simple variant of the salt replication process is developed and explored. Different morphology and shapes have been successfully obtained with “excess salt replication” method (abbreviated as ESR method). Best porosity of about 68 % is obtained with salt particles size of about 3 mm. SEM and EDXS investigation of the composite salt/antimony alloy before NaCl leaching revealed the presence of the lead oxides microfilm coating cell walls and becoming lead carbonates after salt removal. Uniaxial compressive behaviour of the resulting cellular materials is studied for foams with porosities between 45 % and 70 %, and salt grain size ranging between 2.5 and 5 mm. A higher plateau stress is reached compared to the results obtained in the literature working on the aluminium foams. The reproducibility of the process is proved along samples. - U ovom istraživanju izrađene su otvorene ćelije od 25 % antimon-olovnih pjena za moguću primjenu u osvjetljavanju debelih ploča olovno-kiselih baterija. Razvijena je i istražena nova jeftina i jednostavna varijanta procesa repliciranja soli. Različite morfologije i oblici uspješno su dobiveni metodom “prekomjerne replikacije soli” (ESR metodom). Najbolja poroznost od oko 68 % dobivena je pri veličini čestica soli od oko 3 mm. SEM i EDXS ispitivanje kompozitne legure soli/antimona prije ispiranja s NaCl otkrilo je prisutnost mikrofilma olovnih oksida koji oblažu zidove ćelije i nakon uklanjanja soli postaju olovni karbonati. Jednoosno tlačno ponašanje dobivenih materijala ćelije proučava se za pjene s poroznošću između 45 % i 70 % i za veličine zrna soli između 2,5 i 5 mm. Postignuta je veća granica stlačivanja u usporedbi s rezultatima o aluminijskim pjenama dobivenim u literaturi. Ponovljivost postupka dokazana je na uzorcima.

Element determination in hair by ICP-MS method [Elektronička građa] : selection of a suitable sample washing procedure / Anja Bošnjaković, Ankica Sekovanić, Jasna Jurasović, Tatjana Orct, Antonija Sulimanec Grgec, Martina Piasek. - Graf. prikazi.
Bibliografija: 32 jed. - Summary ; Sažetak. - Human hair is a biological sample that is, unlike blood, noninvasively collected and can be used in the assessment of element intake. Before analysis, hair samples need to be washed to eliminate external contamination, for which no standard procedure exists. The present study evaluated the efficiency of different processes for washing hair samples (by non-ionic detergent, acids, solvents, and their mixtures), including ultrasonication before ICP-MS element (As, Ca, Cd, Cu, Fe, Hg, Mg, Mn, Mo, Pb, Se, and Zn) analysis. All tested washing procedures using detergent or solvents were satisfactory, while nitric and hydrochloric acid solutions yielded to “released” and lost elements due to damaged hair (visible discolouration and hair impairment). The application of ultrasonication improved washing efficiency up to 10 %, depending on the tested element and washing procedure. - Ljudska kosa je biološki uzorak koji se, za razliku od krvi, skuplja neinvazivno i može rabiti u procjeni unosa elemenata. Prije analize uzorke kose potrebno je oprati kako bi se odstranila vanjska onečišćenja za što ne postoje standardni postupci. Istraživanjem je procijenjena učinkovitost različitih postupaka pranja uzoraka kose (neionskim detergentom, kiselinama, otapalima i njihovim mješavinama) uključujući primjenu ultrazvuka prije analize elemenata (As, Ca, Cd, Cu, Fe, Hg, Mg, Mn, Mo, Pb, Se, and Zn) metodom ICP-MS. Ispitivani postupci pranja bili su zadovoljavajući, izuzev primjenom dušične i klorovodične kiseline, pri čemu se elementi “otpuštaju” i gube zbog oštećivanja kose (vidljive su promjena boje i pucanje vlasi). Primjena ultrazvuka pospješila je učinkovitost pranja uzoraka do 10 % ovisno o ispitivanom elementu i postupku pranja.

Eudiometrija u djelu Josipa Franje Domina [Elektronička građa] / Nenad Raos. - Ilustr.
Bilješke uz tekst. - Bibliografija: 28 jed. - Sažetak ; Summary. - Josip Franjo (ili Josephus Franciscus) Domin (1754. – 1819.) bio je hrvatski fizičar koji je predavao na sveučilištima u Győru i Pešti. Poznat je po knjizi Dissertatio physica de aeris factitii genesi, natura, et utilitatibus (Fizikalna rasprava o postanku, naravi i koristi umjetnog zraka), Győr, 1784. U Raspravi je opisao više vrsta “umjetnog zraka”, što ih je većinom otkrio Joseph Priestly, a usto postupke i uređaje za njihovo dobivanje te – u drugom dijelu knjige – njihovu upotrebu. U ovom radu raspravlja se o Dominovom opisu eudiometra, uređaja za mjerenje sadržaja kisika (“deflogistoniranog zraka”) u plinskim smjesama njegovom reakcijom s “nitroznim zrakom”, dušikovim(I) oksidom (NO), što ga je izumio Priestley a usavršio Felice Fontana. Naročito je istražena veza “dobrote zraka” s flogistonskom teorijom i teorijom mijazama u Dominovoj Raspravi. - Josip Franjo (or: Josephus Franciscus) Domin (1754–1819) was a Croatian physicist, affiliated at the Universities of Győr and Pest, Hungary. He is noted for his book Physical Treatise on the Genesis, Nature and Utility of Factitious Air, written in Latin (Dissertatio physica de aeris factitii genesi, natura, et utilitatibus) and published in Győr in 1784. In his Treatise he described various kinds of “artificial air”, discovered mostly by Joseph Priestly, as well as methods and devices for their preparation, and – in the second part of the book – their usage. This paper discusses his description of the eudiometer, an apparatus for measurement of oxygen (“dephlogisticated air”) content of gas mixtures by its reaction with “nitrous air” (nitrogen oxide, NO), invented by Priestley and improved by Felice Fontana. Especially discussed was the need for measuring the “goodness of air” in relation to the phlogiston and miasma theories, as presented in the Treatise.

High performance liquid chromatographic analysis of rutin in Allium species from Bosnia and Herzegovina [Elektronička građa] / Mirsada Salihović, Emin Sofić. - Graf. prikazi.
Bibliografija: 22 jed. - Summary ; Sažetak. - Rutin is quercetin heteroside widely present in plants that exhibit many health-beneficial effects, such as strengthening the capillary walls, reducing the harmful effects of LDL cholesterol, and reducing the risk of cardiovascular diseases. Rutin was determined from three Allium species (A. cepa, A. sativum, and A. ursinum) collected in Bosnia and Herzegovina by the HPLC method associated with electrochemical detection. The analysis was performed from methanol extracts of bulb and leaf of garlic, bulb and leaf of onion, and leaves of wood garlic. Rutin was present in all of the examined samples. The highest rutin content was found in garlic leaves (0.78 ± 0.09 mg g–1), and the lowest in onion bulbs (0.04 ± 0.10 mg g–1). The contents of rutin were higher in leaf samples, suggesting that leaves of onion and garlic are recommended as a better natural source of this glycoside. - Rutin je heterozid kvarcetin široko rasprostranjen u biljkama i pokazuje brojne pozitivne učinke na zdravlje, poput jačanja stijenki kapilara, smanjenja štetnih učinaka LDL kolesterola i smanjenja rizika od bolesti krvožilnog sustava. Udio rutina određen je u tri vrste roda Allium (A. cepa, A. sativum i A. ursinum) koje rastu u Bosni i Hercegovini primjenom tekućinske kromatografije visoke učinkovitosti s elektrokemijskom detekcijom (HPLC-ECD). Analiza je provedena u metanolnim ekstraktima lukovice i lista češnjaka, lukovice i lista crvenog luka, lista medvjeđeg luka. Rutin je određen u svim analiziranim uzorcima vrste Allium. Najveći sadržaj rutina određen je u listovima češnjaka (0.78 ± 0.09 mg g–1), a najmanji u crvenom luku (0.04 ± 0.10 mg g–1). Udjeli rutina bili su veći u uzorcima lišća, što sugerira da se listovi luka i češnjaka preporučuju kao bolji prirodni izvor ovog glikozida.

Istraživanje utjecaja inhibitora na koroziju ugljičnog čelika u vodi s biocidom [Elektronička građa] / Ivana Smoljko, Ladislav Vrsalović, Senka Gudić, Klara Đaković. - Ilustr., graf. prikazi.
Bibliografija: 34 jed. - Sažetak ; Summary. - U ovom radu istražen je utjecaj komercijalnog inhibitora (Chemtec FI30) na proces korozije ugljičnog čelika P235 u različitim vodenim otopinama; demineraliziranoj i/ili vodovodnoj vodi uz dodatak komercijalnog biocida (Chemtec BI01). Istraživanja su provedena gravimetrijskom metodom i elektrokemijskim metodama, dok je površina ispitivanog materijala analizirana pomoću optičkog mikroskopa. Analize pokazuju da inhibitor smanjuje brzinu korozije ugljičnog čelika u ispitivanim otopinama, ima visoku djelotvornost te da se može svrstati u anodne inhibitore. Također, uočeno je da inhibitor smanjuje opću i jamičastu koroziju ugljičnog čelika u korozivnim vodenim otopinama. - The effect of a commercial inhibitor (Chemtec FI30) on the corrosion of P235 carbon steel in water (demineralised and/or tap water) with the addition of a commercial biocide (Chemtec BI01) was studied in the present work. This study was carried out by weight loss and electrochemical methods, while specimen’s surface was examined using optical microscope. Results obtained from gravimetric measurement revealed that P235 carbon steel corroded in aqueous solution, i.e., in a solution of demineralised and tap water (50 : 50) and a biocide (Fig. 1), and in tap water with a biocide (Fig. 5). By analysing the surface of carbon steel with an optical microscope, general and pitting corrosion was observed, which was more pronounced in tap water with biocide (Figs. 2 and 6). The addition of a commercial inhibitor significantly reduced the occurrence of corrosion damage on the surface of carbon steel (Figs. 3, 4, 7, and 8) and decreased the rate of carbon steel corrosion in all aqueous solutions (Table 1). Electrochemical investigations performed by open circuit potential measurement, linear polarisation and potentiodynamic polarisation measurement showed that the inhibitor Chemtec FI03 shifted the potential to more positive values (Figs. 9 and 10), increased polarisation resistance (Table 3), decreased the rate of carbon steel corrosion, and had high efficiency in all tested solutions (Table 4). The results obtained showed that this commercial inhibitor could be used as an effective inhibitor for the corrosion of carbon steel in aqueous media.

Kemijski (silikatni) vrt, jedan pokus za obrazovanje u STEM području [Elektronička građa] / Marina Čalogović. - Ilustr.
Bibliografija: 8 jed. - Sažetak ; Summary. - Vizualizacija kemijskih procesa iznimno je važna i korisna u edukaciji kemije. Jedan od takvih pokusa je i kemijski vrt koji nastaje dodavanjem topljive soli metala u otopinu natrijeva silikata ili nekog drugog aniona s kojim metalni ion daje koloidni gel koji stvara polupropusnu membranu. Rastom kemijskog vrta nastaju cjevčice različitih veličina i oblika koje podsjećaju na stabalca i biljke u vrtu. U članku se opisuje izrada kemijskog vrta upotrebom lako dostupnih kemikalija. Taj pokus na jednostavan način predočuje precipitaciju povezanu s osmozom i izvrsno je edukativno sredstvo. - Visualization of chemical processes is of primary importance in chemistry education. One of such experiments is the chemical garden, which is formed by addition of soluble metal salts in a solution of sodium silicate, or some other anion that forms a colloid gel with a metal ion. Gel forms tubular semi-permeable membranes, which morphologically resemble garden plants. This paper describes preparation of a chemical garden with easily obtainable chemicals. This simple experiment visualizes osmosis-related precipitation and is a very convenient teaching tool.

Kilogram i mol u novome ruhu - o korjenitim promjenama u Međunarodnom sustavu jedinica (SI) [Elektronička građa] / Vjera Lopac. - Ilustr., graf. prikazi.
Bibliografija: 17 jed. - Sažetak ; Summary. - Od 20. svibnja 2019. jedinice Međunarodnog sustava SI definirane su s pomoću sedam prirodnih konstanti, νCs, c, h, e, kB, NA i Kcd. Promjene su prihvaćene na 26. sjednici Opće konferencije za utege i mjere (Conférence générale des poids et mesures, CGPM), održanoj u Versaillesu u Francuskoj 18. studenoga 2018. U članku su navedene stare i nove definicije osnovnih jedinica sustava SI, kao i matematički izrazi koji se dobiju rješavanjem algebarskih jednadžbi implicitno sadržanih u novim definicijama. Posebna je pozornost posvećena povijesti i novim definicijama jedinica kilogram i mol te metodičkim aspektima njihova tumačenja. Navedeni su i odabrani numerički primjeri, korisni za primjenu u srednjoškolskoj i sveučilišnoj nastavi kemije. - At the end of the year 2018, news of a radical transformation of the International System of Units (SI) spread worldwide. Particular excitement was caused by the abandonment of the 140-year-old prototype of kilogram, the base SI unit of mass, stored under the glass bell in Sèvres near Paris, France, and by the introduction of a new definition of kilogram using the quantum-mechanical Planck constant h. The changes were accepted at the 26th session of the General Conference on Weights and Measures (CGPM) held in Versailles, France, on November 18, 2018, and entered into force on May 20, 2019. In the new definitions the SI units are derived by means of seven natural constants, νCs, c, h, e, kB, NA, and Kcd. The article presents the old and the new definitions of the seven base units of the SI system together with the mathematical expressions obtained by solving algebraic equations implicitly contained in the new definitions. The newly defined set of natural units for the base and derived quantities is discussed. The properties and the history of units kilogram and mole as well as the educational aspects of their interpretation are given special attention. Some selected numerical examples are proposed for use in the high school and university chemistry classes.

Kinetička analiza izotermne razgradnje poli(etilen-oksida) modificiranog fenil hepta izobutil poliedarskim oligomernim silseskvioksanima [Elektronička građa] / Nataša Stipanelov Vrandečić, Matko Erceg, Branka Andričić, Petra Ćerdić. - Graf. prikazi.
7. hrvatski simpozij o kemiji i tehnologiji makromolekula, Zagreb, 27.9.2019. - Bibliografija: 18 jed. - Sažetak ; Summary. - Čvrsti polimerni elektroliti na bazi poli(etilen-oksida) (PEO) i litijevih soli imaju slabu ionsku provodnost pri temperaturi uporabe, a osnovni razlog je visok stupanj kristalnosti PEO-a. Udio kristalne faze u PEO-u može se smanjiti dodatkom nanočestica, u koje spadaju i poliedarski oligomerni silseskvioksani (POSS). U ovom radu upotrijebljeni su metil-, fluoro- i kloro-fenil hepta izobutil poliedarski oligomerni silseskvioksani. Istraživan je njihov utjecaj na kinetiku izotermne razgradnje PEO-a. Aktivacijska energija, predeksponencijalni faktor i kinetički model izračunati su pomoću programa Netzsch Thermokinetics Professional. Utvrđeno je da se proces izotermne toplinske razgradnje odvija kroz jedan stupanj koji je najbolje opisan autokatalitičkim modelima. - Poly(ethylene oxide) (PEO) and lithium salts based solid polymer electrolytes exhibit low ionic conductivity at the service temperatures, the main reason being the high crystallinity of PEO. Degree of crystallinity is often lowered by addition of nanoparticles, among them being a very interesting group known as polyhedral oligomeric silsesquioxanes (POSSs). In this work, the influence of POSS nanoparticles (methyl-, fluoro-, and chloro-phenil heptaisobutyl POSS) on kinetics of isothermal PEO degradation was investigated. Activation energy, pre-exponential factor, and kinetic model were determined using Netzsch Thermokinetics Professional program. It was found that the process of isothermal degradation occurs through one step, best described by autocatalytic models. According to Fig. 2 and Table 2, all investigated samples at 360, 370, and 380 °C after 60 min reach constant mass plateau with residual mass (mf) 3–7 %. In this temperature range, degradation of both PEO and POSSs occur. Before starting the kinetic analysis, the time necessary to gain isothermal conditions was subtracted. Activation energy (E) and pre-exponential factor (A) calculated using linear regression (LR), as well as the kinetic model of thermal degradation f(α) are summarised in Table 4. Activation energies of PEO/POSS 1, PEO/POSS 3 i PEO/POSS 5 samples are similar to those of PEO. The highest and lowest value of activation energy for PEO/POSS 4 and PEO/POSS 2 samples, respectively, is the result of their inherent thermal stability. Dependence of activation energy on conversion is of the same shape for all samples, implying the same mechanism of thermal degradation. DTG curves exhibit one degradation step only. Results of F-test (Table 3) indicate that extended Prout-Tompkins model as well as other autocatalytic models are statistically the best for description of the isothermal degradation of PEO and PEO/POSS composites.

Bibliografija: 21 jed. - Sažetak ; Summary. - U ovom radu istražuju se mogućnosti povećanja brzine oslobađanja lurasidon-hidroklorida, antipsihotika druge generacije, pripravom čvrstih disperzija procesom liofilizacije. FTIR, DSC te XRPD ispitivanja provedena su s ciljem detekcije potencijalnih interakcija između lurasidon-hidroklorida i polimernih matrica koje mogu znatno povećati topljivost djelatne tvari i osigurati brže oslobađanje iz dozirnog oblika. Takve čvrste disperzije i pomoćne tvari upotrijebljene su u pripravi tableta čija su vremena raspadanja manja od 3 min. Profili otapanja u laboratorijskom okruženju ukazuju na brže oslobađanje djelatne tvari iz raspadljivih tableta u odnosu na čisti lurasidon-hidroklorid. - This paper investigates the possibilities for release rate enhancement of lurasidone hydrochloride, a second-generation antipsychotic, by preparing solid dispersions via lyophilisation process. FTIR, DSC, and XRPD measurements have been performed in order to detect potential interactions between lurasidone hydrochloride and polymer matrices that might significantly increase drug solubility and provide faster release from the dosage form. Such solid dispersions and excipients have been used in the preparation of tablets that disintegrate in less than 3 min. In vitro dissolution profiles indicate a higher drug release rate from disintegrating tablets in comparison to pure LRS HCl.

Na kraju, navedeno je kako unaprijediti stečena znanja i vještine kroz pitanja povezana s vrijednostima pH i puferima. - Buffers are of high importance for pH measurement and control, which is crucial in many everyday scientific and industrial activities. The aim of this article was to elucidate the physicochemical parameters of buffers. Explained are the process and background of pH electrode calibration, as are described the problems that may arise in pH measurement, and their solutions. The focus of this article is the application and assessment of this knowledge in education through examples and numerical problems. The practical examples facilitate the learning of basic concepts related to pH and buffers. We clarify the correct definition of pH value, the Henderson-Hasselbalch equation and its limitations, the use of visual indicators with buffers, the connection between Le Chatelier’s principle and buffers, and what is important in pH measurement. A special mention is given to the influence of temperature in pH electrode calibration, pH measurement, and expressing the pH value. Finally, we suggest how to further improve the students’ knowledge and skills through questions on problems related to pH value and buffers.

Bibliografija: 14 jed. - Sažetak ; Summary. - Na području Centralnog uređaja za pročišćavanje otpadnih voda grada Zagreba (CUPOVZ) od 2004. godine provode se ciljana mjerenja imisijskih koncentracija sumporovodika (H2S), amonijaka (NH3) i ukupnih merkaptana (R−SH). U ovom radu prikazani su rezultati mjerenja provedenih tijekom 2017. godine na dvije mjerne postaje: Biologija-sjever i Biologija-jug, koje su smještene u krugu CUPOVZ-a. 24-satni uzorci H2S, NH3 i R−SH sakupljani su po mjesec dana u svakom godišnjem dobu. Koncentracije H2S, NH3 i R−SH na obje mjerne postaje pokazuju statistički značajnu sezonsku ovisnost (p <0,05). Promatrajući sva mjerna razdoblja zajedno, pronađene su visoke pozitivne korelacije između svih onečišćujućih tvari i temperature te negativne s tlakom. - Since 2004, continuous measurements of hydrogen sulphide (H2S), ammonia (NH3), and mercaptan (R−SH) levels in air have been monitored in the area of the Central wastewater treatment plant Zagreb (CUPOVZ). At two measuring sites within the CUPOVZ area, Biology-north and Biology-south, for a month in every season in 2017, twenty-four hour samples of H2S, NH3, and R−SH were collected. Measured concentrations of gaseous pollutants showed statistically significant seasonal variations (p <0.05) at both measuring stations. For the overall period, high positive correlations were found between all pollutants and temperature, and negative with pressure.

Redoks-svojstva ferocenom supstituiranih nukleobaza [Elektronička građa] / Mateja Toma, Valerije Vrček. - Graf. prikazi.
Bibliografija: 29 jed. - Sažetak ; Summary. - Pripravljena je serija ferocenom supstituiranih purinskih nukleobaza 1-10 te su izmjereni njihovi redoks-potencijali metodom cikličke voltametrije. Svi ispitani spojevi pokazali su reverzibilnu jednoelektronsku oksidaciju u rasponu potencijala od 330 do 470 mV. Također je uočena razlika redoks-potencijala od 100 mV između N7 i N9 regioizomera ispitivanih nukleobaza. Ispitana je i acelularna aktivnost stvaranja reaktivnih kisikovih vrsta (ROS) kolorimetrijskom metodom s DCFH2-DA te je utvrđeno da konjugati generiraju ROS, dok su ferocen i nukleobaze neaktivni. Različiti supstituenti na purinskom prstenu utječu na stvaranje ROS-a, što omogućuje dizajn biološki aktivnih konjugata ferocena i prikladnih nukleobaza. - A series of ferrocene-substituted purine-nucleobase derivatives 1-10 were synthesized and their redox potential was measured by cyclic voltammetry. Measured compounds showed a reversible one-electron oxidation in the range of 330–470 mV. A difference of 100 mV between N7 and N9 regioisomers was observed. In order to examine the tendency of ferrocene-nucleobase conjugates to produce reactive oxygen species (ROS), an acellular screening with DCFH2-DA assay was carried out. The nucleobases coupled with ferrocene generated ROS, while neither ferrocene itself nor the nucleobases were active. Changing the substituents on the purine ring can significantly influence the ROS generation of ferrocene-substituted nucleobases, which support design of biologically active ferrocene-nucleobase conjugates.

Specijalna teorija relativnosti u kemiji [Elektronička građa] / Nenad Raos. - Graf. prikazi.
Bibliografija: 26 jed. - Sažetak ; Summary. - Primjena specijalne teorije relativnosti u kemiji nije česta; potreba za njom javlja se tek pri proračunu svojstava teških atoma, u kojima se elektroni gibaju relativističkim brzinama. U članku su dati primjeri objašnjenja osebujne boje zlata, niskog tališta žive, boje bizmutovih i olovnih spojeva, utjecaja relativističke korekcije na proračun oblika klastera zlata, duljine veza u spojevima 11. skupine i lantanoida te napona olovnog akumulatora i baterije Zn/HgO. Usto su prikazane osnove specijalne teorije relativnosti i kvantne kemije. - Application of Einsteinʹs special theory of relativity in chemistry seems to be superfluous; energies are too low. The average velocity of electron in hydrogen atom (1s1) is 1/135 c, making its actual mass only 26,6 ppm larger than the rest of the mass. However, for heavier elements (about Z > 60), relativistic effects have to be taken into account and, more than that, many phenomena cannot be explained without ascribing a new mass to electrons, in accordance with Einsteinʹs theory. In this paper, such phenomena are described: colour of metallic gold and Bi and Pb compounds, low melting point of mercury, contraction of Ln-X bond of lanthanoide trihalides, voltage of lead-acid and Zn/HgO battery, and the shape of gold clusters. In addition, essentials of Einsteinʹs theory and quantum chemistry are presented, as well as the problems concerning the validity of Lavoisierʹs law.

Suvremena sredstva za dekontaminaciju bojnih otrova [Elektronička građa] : II. dio – metalni oksidi / Dragutin Tušek, Ivana Cetina, Vesna Pehar. - Ilustr.
Nastavak iz br. 11/12/2019. - Bibliografija: 45 jed. - Sažetak ; Summary. - Metalni oksidi su netoksični spojevi koji se upotrebljavaju kao praškasti dekontaminanti, jednostavni su za primjenu i skladištenje te imaju vrlo visok površinski kapacitet. Metalni oksidi, posebno u nanoformi pokazuju odlična fizisorpcijska i kemisorpcijska svojstva za sorpciju toksičnih spojeva uključujući bojne otrove i njihove imitante. Iako se istražuju sorpcijska i dekontaminacijska svojstva mnogih metalnih oksida, najveću komercijalnu iskoristivost pokazali su magnezijev, aluminijev i titanijev oksid. Neki metalni oksidi u nanoformi pokazuju svojstvo destruktivne adsorpcije, što je vrlo interesantno u istraživanju pogodnosti metalnih oksida u svrhu dekontaminacije bojnih otrova i opasnih zagađivala uključujući kemijske, biološke i radiološke tvari. Uz metalne okside istražuju se i metalni kationi kao dopanti drugim metalnim oksidima i zeolitima u svrhu poboljšanja sorpcijskih svojstava dopaniranih spojeva. - Metal oxides are nontoxic compounds that are, in their powder form, used as decontaminating agents; they are simple to use and apply, easy to store, and have very high active surface capacity. Metal oxides, especially in nanoform, show excellent physisorption and chemisorption properties towards toxic compounds like chemical warfare agents and their simulants. Although sorption and decontamination properties of many metal oxides are being researched, only magnesium, aluminum, and titanium oxide showed the greatest commercial usability. Some metal oxides in nanoform show destructive adsorption properties, which is very interesting in research of the metal oxides suitable for decontamination of chemical warfare agents and other chemical, biological, and radiological toxic substances. Besides metal oxides, research focus is also on metal cations used as dopants in other metal oxides and zeolites in order to improve sorption properties.

Svojstva nanokompozita otpadnog poliamidnog praha i titanijeva dioksida [Elektronička građa] / Domagoj Šubarić, Andrea Lončarević, Zrinka Buhin Šturlić, Sanja Lučić Blagojević. - Ilustr., graf. prikazi.
7. hrvatski simpozij o kemiji i tehnologiji makromolekula, Zagreb, 27.9.2019. - Bibliografija: 23 jed. - Sažetak ; Summary. - Selektivno lasersko sinteriranje (SLS) jedan je od važnijih postupaka 3D ispisa koji se u današnje vrijeme sve više primjenjuju za dobivanje različitih modela. Najvažniji polimerni materijali koji se upotrebljavaju u tom procesu su poliamidi. Značajan nedostatak tog procesa je velika količina otpadnog polimernog praha. Stoga je cilj ovoga rada bio istražiti utjecaj dodatka nanočestica titanijeva dioksida (TiO2) na toplinska i mehanička svojstva otpadnog poliamidnog praha (PA 2200). U ovom radu pripremljeni su nanokompoziti PA/TiO2 u rasponu masenog udjela punila 1 – 5 %, postupkom zamješavanja punila u talinu polimera u gnjetilici Brabender. Aglomerati nanopunila vidljivi su na SEM mikrografiji 5 %-tnog PA/TiO2 nanokompozita. Rezultati diferencijalne pretražne kalorimetrije (DSC) ukazuju na djelovanje nanočestica TiO2 kao heterogenih nukleacijskih centara. Također, dodatak nanopunila pospješuje stvaranje stabilnijih i uređenijih kristalnih struktura poliamidne matrice. Termogravimetrijskom analizom (TGA) dokazano je da dodatak TiO2 nanopunila povećava temperaturu početka razgradnje PA matrice, to jest poboljšava toplinsku postojanost PA matrice i neznatno povećava vrijednosti toplinske vodljivosti nanokompozita u odnosu na čistu polimernu matricu. Ispitivanjem mehaničkih svojstava uzoraka uočeno je smanjenje vrijednosti sekantnog modula te neznatne promjene naprezanja i istezanja u točki popuštanja s povećanjem udjela punila u nanokompozitu. - The PA 2200 waste powder generated during selective laser sintering (SLS) process is an important environmental and economic problem. In order to test and modify the properties of the waste powder, nanocomposites based on polyamide matrix and TiO2 nanoparticles were prepared in this work. Agglomerates of the TiO2 nanofiller are visible on the SEM micrographs for the nanocomposite with 5 wt. % of the nanofiller (Fig. 1). The DSC analysis indicates an increase in crystallization temperature (Tc) by the addition of filler to the polymer matrix and it can be concluded that the TiO2 nanoparticles represent the nucleation centres in the PA matrix (Fig. 2, Table 1). In systems with 4 and 5 wt. % TiO2 crystallization enthalpy (ΔHc) and melting enthalpy (ΔHm) are higher than the values for the polyamide matrix (Table 1), indicating that the nanoparticles promote crystallization of the PA matrix. The results of TG analysis imply a positive effect of the TiO2 nanoparticles on the onset of thermal decomposition, which is most pronounced in the system with 3 wt. % TiO2 (Fig. 3, Table 2). As thermal degradation progresses further, the positive effect of the addition of TiO2 nanoparticles becomes less pronounced and finally becomes negative in the final stages, i.e. TiO2 nanoparticles accelerate the degradation. The thermal conductivity values (λ) are slightly higher for the nanocomposites relative to the pure PA matrix (Fig. 4) due to the formation of a more ordered structure of the polymer matrix by the addition of TiO2 and/or the formation of so-called conductive pathway. The results of the mechanical test indicate that the addition of TiO2 nanofiller decreases the values of the secant modulus (E), while the values of the yield stress (σ2>yy

Bibliografija: 8 jed. - Summary. - In search of a new class of potential antimicrobial agents, novel ammonium salts based on quinuclidine-3-ol and pyridine-4-aldoxime with different lengths of alkyl chains were synthesized and analyzed. In addition to their potential biological application, newly synthesized salts containing terminal bromine could possibly be used for the synthesis of more potent bisquaternary salts. Methods: The commercially available quinuclidine-3-ol and pyridine-4-aldoxime were used for the synthesis of new derivatives with the appropriate alkyl chains. The purity of the synthesized salts was tested by thin-layer chromatography on an aluminum plate where aluminum oxide was used as a stationary phase. Melting points were determined in open capillaries using an instrument for melting point determination and the obtained values were left uncorrected. The FTIR spectra were recorded with a spectrometer and the data were analyzed in cm-1. Results: All the synthesized compounds, which contained heterocyclic moiety and alkyl chains (with or without a terminal bromine atom), were obtained in very good yields under the simple quaternization conditions. The better product yields were observed in reactions with quinuclidine3-ol (46-95%) compared to those with pyridine-4-aldoxime (49-59%). The obtained products were analyzed and confirmed by the thin-layer chromatography, the melting point measurement and the FTIR spectra. Conclusion: The observed difference in product yields could be explained by the different basicity of the nitrogen atom of quinuclidin-3-ol than that of pyridine-4-aldoxime. All prepared salts have a positively charged nitrogen atom as a part of their polar “head” and a long hydrocarbon chain as the non-polar “tail”. Such a structure allows electrostatic interaction with the negatively charged bacterial membrane and causes it to be disrupted. The structure of the prepared salts containing long alkyl chains could be crucial for their antimicrobial activity.

Ultrasound-assisted crystallisation of magnesium hydroxide from seawater [Elektronička građa] / Jelena Jakić, Miroslav Labor, Dražan Jozić, Vanja Martinac, Ivona Horvat. - Ilustr., graf. prikazi.
Bibliografija: 31 jed. - Summary ; Sažetak. - High purity magnesium hydroxide has been synthesised from seawater with the addition of dolomite lime as reagent. High intensity ultrasound-assisted crystallization of magnesium hydroxide was carried out during precipitation with the intention to obtain fine particles of Mg(OH)2 as well as to prevent their agglomeration. Investigations were conducted on magnesium hydroxide samples in the form of sludge and voluminous powder. The composition, morphology, and properties of the product were determined by chemical, XRD, FTIR, and SEM/EDS analysis. The particle size distribution was detected by the laser light scattering method. The results showed that the mean particle size of magnesium hydroxide sludge was 5.75 µm, while voluminous powder was 7.58 µm. The morphology of magnesium hydroxide voluminous powder was in the form of aggregated filamentous (up to 300 nm in size) or flake structures. - Magnezijev hidroksid visoke čistoće sintetiziran je iz morske vode uz dodatak dolomitnog vapna. Ultrazvukom visokog intenziteta potpomognuta kristalizacija magnezijeva hidroksida tijekom precipitacije odvijala se u svrhu dobivanja što finijih čestica Mg(OH)2 i sprječavanja njihove aglomeracije. Ispitivanja su provedena na uzorcima magnezijeva hidroksida u obliku mulja i voluminoznog praha. Sastav, morfologija i svojstva dobivenog produkta analizirani su kemijskom, XRD, FTIR i SEM/EDS analizom. Raspodjela veličine čestica određena je metodom raspršenja laserskog svjetla. Rezultati ukazuju na to da je srednja veličina čestica magnezijeva hidroksida u obliku mulja 5,75 µm, dok je u voluminoznom prahu 7,58 µm. Morfologija voluminoznog praha magnezijeva hidroksida je u obliku aglomeriranih nitastih (duljine do 300 nm) i ljuspičastih struktura.

Utjecaj modelnih otopina na poli(3-hidroksibutirat)/montmorilonit kompozite [Elektronička građa] / Sanja Perinović Jozić, Ana Mihovilović, Branka Andričić. - Graf. prikazi.
7. hrvatski simpozij o kemiji i tehnologiji makromolekula, Zagreb, 27.9.2019. - Bibliografija: 22 jed. - Sažetak ; Summary. - Cilj ovog rada bio je pripremiti poli(3-hidroksibutirat)/montmorilonit (PHB/MMT) kompozite na laboratorijskoj preši uz zagrijavanje te odrediti utjecaj različitih modelnih otopina na kompozite i migraciju punila. Analiza modelnih otopina nakon ispitivanja migracije provedena je pomoću UV/Vis spektroskopije. Zbog utvrđene hidrolize PHB-a pod utjecajem modelnih otopina nemoguće je odrediti migraciju MMT-a iz kompozita PHB/MMT. Diferencijalna pretražna kalorimetrija (DSC) potvrdila je razgradnju PHB-a. Provedenim istraživanjem ukazalo se na potencijal uporabe UV/Vis spektroskopije kod ispitivanja utjecaja modelnih otopina na polimerne kompozite. - The aim of this work was to prepare poly(3-hydroxybutyrate)/montmorillonite (PHB/MMT) composites on the laboratory press with heating, and to determine the influence of different food simulants on the composites and the filler migration. Analysis of the food simulants after migration testing was conducted with UV/Vis spectroscopy. Due to the established hydrolysis of PHB under the influence of the food simulants, it was impossible to determine the migration of MMT from PHB/MMT composites. Differential scanning calorimetry (DSC) confirmed the degradation of PHB. This research showed the potential of UV/Vis spectroscopy in dealing with the influence of food simulants on polymer composites.

Utjecaj natrijeva alginata na svojstva poli(etilen-oksida) kao matrice za pripravu čvrstih polimernih elektrolita [Elektronička građa] / Sanja Perinović Jozić, Antonija Sesar, Zoran Grubač, Branka Andričić. - Ilustr., graf. prikazi.
Bibliografija: 20 jed. - Sažetak ; Summary. - Istraživan je utjecaj natrijeva alginata (NaAlg) na strukturu i svojstva filmova poli(etilen-oksida) (PEO) izlivenih iz vodenih otopina primjenom infracrvene spektroskopije s Fourierovom transformacijom (FT-IR), diferencijalne pretražne kalorimetrije (DSC), neizotermne termogravimetrije (TG) i elektrokemijske impedancijske spektroskopije (EIS). Cilj istraživanja je pronalaženje optimalne mješavine za pripravu filma čvrstog polimernog elektrolita (SPE) za litij-ionske baterije (LIB). U filmovima mješavina PEO/NaAlg stvaraju se vodikove veze između PEO-a i NaAlg-a te nastaju mješljive mješavine s manjim udjelom kristalne faze u odnosu na film čistog PEO-a. Filmovi mješavina toplinski su nestabilniji od filma čistog PEO-a i pokazuju dielektrična svojstva. Zbog najmanjeg udjela kristalne faze PEO-a mješavina 80PEO/20NaAlg može biti polimerna matrica koja bi dodatkom litijeve soli tvorila pogodan SPE. - Investigation of the influence of sodium alginate (NaAlg) on the structure and properties of poly(ethylene oxide) (PEO) films cast from aqueous solutions was performed by Fourier transform infrared spectroscopy (FT-IR), differential scanning calorimetry (DSC), non-isothermal thermogravimetry (TG), and electrochemical impedance spectroscopy (EIS). The research aimed to find the optimal blend for the preparation of a solid polymer electrolyte (SPE) film for lithium-ion batteries (LIB). In PEO/NaAlg blend films, hydrogen bonds are formed between PEO and NaAlg, the blends are miscible, and have a lower content of crystalline phase compared to pure PEO film. The films of the blends are more thermally unstable than the film of pure PEO, and show dielectric properties, but the blend 80PEO/20NaAlg is suitable for the preparation of SPE by addition of lithium salt due to the lowest content of PEO crystalline phase.

Bibliografija: 31 jed. - Sažetak ; Summary. - Od utemeljenja Zavoda, akademske godine 1961./62., njegova znanstveno-istraživačka djelatnost bila je usmjerena na elektrokemijska istraživanja metala, pojavu pasiviteta i inhibiciju korozije. Kasnije, ponajprije primjenom elektrokemijskih metoda, proučavaju se fenomeni na granici faza metal│anodni sloj│elektrolitna otopina koji su od značaja za kemijske izvore struje i poluvodičke sustave. Tijekom posljednjih deset godina istraživanja se usmjeravaju u dva smjera: i) ispitivanje utjecaja legirajućih elemenata na dizajn otpornih materijala i biofunkcionalizacija površine biorazgradljivih i biokompatibilnih metalnih implantata; ii) modifikaciju elektroda i njihovih površina u svrhu razvoja novih elektroanalitičkih metoda za određivanje teških metala i biomolekula. - Since the establishment of the Department of General and Inorganic Chemistry in 1961, at the Faculty of Chemistry and Technology, University of Split, its scientific interest and investigations were focused toward electrochemical research. Consequently, electrochemistry became the backbone of the scientific research and development of the Department. In the last 10 years, scientific interest has been focused on the influence of alloying elements on design of corrosion resistance materials, as well as biofunctionalisation of biodegradable and biocompatible metal-based implants. In addition, development of various electroanalytical methods based on modified electrodes as sensing part of sensors, have been in focus in the recent period. The developed sensors were used for determination of heavy metals or biomolecules.

Assessing vulnerability for inhabitants of Dhaka City considering flood-hazard exposure [Elektronička građa] / Md. Enamul Huq, Qimin Cheng, Orhan Altan, A. Z. M. Shoeb, Mallik Akram Hossain, Md. Nazirul Islam Sarker, Nayyer Saleem, Akib Javed, Xiaoyi Longg, Ahmed Abdullah Al Dughairi, Md. Masud Parves Rana, Abdullah Al Mamun, Md. Mahabubur Rahman. - Graf. prikazi.
Bibliografija: str. 124-129. - Summary ; Sažetak. - Global flood hazard is gradually increasing. Though it is impossible to avoid them, losses and damage of hazards (e.g., floods, cyclones, and earthquakes) could be efficiently reduced by reducing household vulnerability with appropriate measures. This study aims to quantitatively measure the household vulnerability of flood hazards as a mitigation tool. It also proposed a unique approach to quantify flood-hazard household vulnerability, and shows its application in the flood prone city of Dhaka as an example case. Data were collected from both slum and non-slum areas to cover the entire urban habitat, and to compare their level of flood vulnerability. A total of 300 households were surveyed by structured questionnaire on the basis of five factors (economic, social, environmental, structural, and institutional) of flood vulnerability. The analytical hierarchy process (AHP) was applied to measure individual household vulnerability scores by using the relative weightage of variables and indicators with proper standardisation. Analytical results demonstrated that 63.06% slum and 20.02% non-slum households were highly vulnerable to floods. In addition, this paper determined and assessed responsible factors for household flood vulnerability in Dhaka. For structural vulnerability, results exhibited that 82% of slum households were highly vulnerable, and 95.3% of non-slum households were moderately vulnerable. Socially, 67.3% of slum and 78.7% of non-slum households were moderately and low-vulnerable. The majority of slum and non-slum households (84% and 59.3%, respectively) showed high and moderate vulnerability with respect to economic vulnerability. Moreover, 69.3% of slum and 65.3% of nonslum household institutional vulnerability levels were high. Of slum inhabitants, 63.3% were environmentally at high risk, and 78% of non-slum habitats were in the low-vulnerability category. - Globalna opasnost od poplave postupno se povećava. Iako ih je nemoguće izbjeći, gubici i šteta od opasnosti (npr. poplave, cikloni i potresi) mogu se učinkovito smanjiti smanjenjem ranjivosti kućanstava odgovarajućim mjerama. Cilj ove studije je kvantitativno mjerenje ranjivosti kućanstava obzirom na opasnosti od poplave kao alata za njihovo ublažavanje. Također je predložen jedinstveni pristup za kvantificiranje ugroženosti kućanstava obzirom na opasnosti od poplave, a kao primjer predstavljena je primjena u gradu Dhaki sklonom poplavama. Podaci su prikupljeni i sa siromašnih i bogatih područja kako bi bilo pokriveno cijelo urbano područje te kako bi se usporedila razina ugroženosti od poplava. Ukupno 300 kućanstava anketirano je strukturiranim upitnikom na temelju pet čimbenika (ekonomskih, socijalnih, okolišnih, strukturnih i institucionalnih) ugroženosti od poplava. Analitički hijerarhijski postupak (AHP) primijenjen je za mjerenje pojedinačnih rezultata ranjivosti kućanstva korištenjem relativne težine varijabli i pokazatelja uz pravilnu standardizaciju. Analitički rezultati pokazali su da je 63,06% siromašnih kućanstava i 20,02% bogatih kućanstava vrlo osjetljivo na poplave. Uz to, ovaj je rad utvrdio i procijenio čimbenike odgovorne za ranjivost kućanstava u Dhaki. Što se tiče strukturne ranjivosti, rezultati su pokazali da je 82% kućanstava u siromašnim krajevima bilo visoko ranjivo, a 95,3% kućanstava koja nisu iz siromašnih četvrti bilo je umjereno ranjivo. Društveno, 67,3% siromašnih i 78,7% kućanstava koja nisu iz siromašnih naselja bila su umjereno i slabo ranjiva. Većina kućanstava u siromašnoj i nesiromašnoj četvrti (84%, odnosno 59,3%) pokazala je visoku i umjerenu ekonomsku ranjivost. Štoviše, za 69,3% siromašnih i 65,3% nesiromašnih kućanstava institucionalna ranjivost je bila visoka.

Calculating the characteristics of flash floods on small rivers in the Mountainous Crimea [Elektronička građa] / Valeriya Ovcharuk, Eugene Gopchenko, Olena Todorova, Kateryna Myrza. - Ilustr., graf. prikazi.
Bibliografija: str. 41-42. - Summary ; Sažetak. - The maximal surface runoff from territory of the Crimean Mountains is represented as a runoff of small rivers that flow through the western and eastern part of the northern slope and from the southern coast. The materials from 54 water gauging stations (WGS) were used to characterize the maximum runoff during rain and meltwater-rain floods on the rivers in the Crimean Mountains. A modified reduction structure of a calculation formula was used for valuation of the maximal runoff of different origin flash flood for rivers at the Mountainous Crimea. The main parameters of the proposed model are summarized as dependencies on the average height of the catchments and generalized in the form of a map. It is also possible to use the second variant of the suggested method taking into account the factor of underlying surface is introduced. Comparison of the calculated values of maximal runoff shows good convergence with both the initial information, and the largest values in the observation period. - Maksimalno površinsko otjecanje s područja krimskih planina prikazano je kao otjecanje malih rijeka koje teku kroz zapadni i istočni dio sjeverne padine te s južne obale.

Modificirani oblik redukcijske formule korišten je za procjenu maksimalnog otjecanja pri naglim poplavama rijeka u planinskom području Krima. Glavni parametri predloženog modela mogu se prikazati u ovisnosti o prosječnoj nadmorskoj visini sliva u formi karata. Druga mogućnost predložene metode je uzimanje u obzir same podloge.

Comparison of the Bouguer reduction approach for the satellite gravity data [Elektronička građa] : case study of the eastern Tibetan Plateau and its adjacent areas / Fan Luo, Jiayong Yan, Kun Zhang, Chong Zhang, Guangming Fu, Xin Tao. - Ilustr., graf. prikazi.
Bibliografija: str. 257-260. - Summary ; Sažetak. - Satellite gravity data are widely used in the field of geophysics to study deep structures at the regional and global scales. These data comprise free-air gravity anomaly data, which usually need to be corrected to a Bouguer gravity anomaly for practical application. Bouguer reduction approaches can be divided into two methods based on the coordinate system: the spherical coordinates method (SBG) and the Cartesian coordinates method; the latter is further divided into the CEBG and CBG methods, which do and do not include the Earth’s curvature correction. In this paper, free-air gravity anomaly data from the eastern Tibetan Plateau and its adjacent areas were used as the basic data to compare the CBG, CEBG, and SBG Bouguer gravity correction methods. The comparison of these three Bouguer gravity correction methods shows that the effect of the Earth’s curvature on the gravitational effect increases with increasing elevation in the study area. We want to understand the inversion accuracy for the data obtained by different Bouguer gravity reduction approaches. The depth distributions of the Moho were obtained by the interface inversion of the Bouguer gravity anomalies obtained by the CBG, CEBG, and SBG, and active seismic profiles were used as references for comparison and evaluation. The results show that the depths of the Moho obtained by the SBG inversion are more consistent with the measured seismic profile depths. Therefore, the SBG method is recommended as the most realistic approach in the process of global or regional research employing gravity data. - Gravimetrijski satelitski podaci u širokoj su primjeni u geofizici u proučavanju dubokih struktura na regionalnoj i globalnoj razini. Ti podaci uključuju i gravitacijske anomalije slobodnog zraka, koje obično treba korigirati na Bouguer-ovu gravitacijsku anomaliju, radi praktične primjene. Metode Bouguer-ove redukcije mogu se podijeliti u dvije skupine ovisno o primijenjenom koordinatnom sustavu: 1. metoda sfernih koordinata (SBG) i 2. metoda kartezijevih koordinata; potonja se dalje dijeli na metode CEBG i CBG, koje uključuju, odnosno ne uključuju korekciju zbog zakrivljenosti Zemlje. U ovom su radu podaci o gravitacijskim anomalijama slobodnog zraka s Istočno-tibetanske visoravni i susjednih područja korišteni kao ulazni podaci za usporedbu triju metoda Bouguer-ove korekcije gravitacije: CBG, CEBG i SBG. Usporedba ove tri Bouguer-ove metode za gravitacijsku korekciju pokazala je da u istraživanom području učinak zakrivljenosti Zemlje na gravitaciju raste s povećanjem nadmorske visine. Cilj je bio shvatiti točnost inverzije za podatke dobivene različitim pristupima Bouguer-ovim anomalijama gravitacije. Raspodjele dubine Mohorovičićevog diskontinuiteta dobiveni su inverzijom Bouguer-ovih gravitacijskih anomalija dobivenih primjenom CBG, CEBG i SBG metoda, a aktivni seizmički profili korišteni su kao reference za usporedbu i ocjenu. Rezultati pokazuju da se dubine Mohorovičićevog diskontinuiteta dobivene SBG inverzijom bolje podudaraju s izmjerenim dubinama na seizmičkom profilu. Stoga se SBG metoda preporučuje kao najrealističniji pristup u postupku globalnih ili regionalnih istraživanja koja koriste gravimetrijske podatke.

Conversion between the local magnitude (ML) and the moment magnitude (Mw) for earthquakes in the Croatian Earthquake Catalogue [Elektronička građa] / Marijan Herak. - Graf. prikazi.
Bibliografija: str. 206-207. - Summary ; Sažetak. - Based on 153 earthquakes (1959–2020) listed in the Croatian Earthquake Catalogue, a conversion relation was obtained between the local magnitude ML,CR and the corresponding moment magnitude Mw as reported by the global and regional agencies. As errors were present in both variables the York regression was used. The best fit line is given by: MwL = (–0.106 ± 0.122) + (1.002 ± 0.027) ML,CR (coefficient of determination R2 = 0.90). The earthquakes considered occurred in Croatia and the neighbouring regions, and their local magnitudes ML,CR ranged between 3.5 and 6.5. Residual analysis suggests that an artificial positive magnitude shift of up to 0.3 magnitude units may have occurred in the early 1980s, when Wiechert mechanical seismographs were replaced by the instruments with velocity proportional recordings without proper recalibration of the magnitude formula. The slope of the regression close to 1.0 indicates that on the average the faults’ aspect ratio (width/length) is about 1/2. - Na temelju podataka o lokalnoj magnitudi (ML,CR) iz Hrvatskog kataloga potresa, izvedena je konverzijska relacija između ML,CR i momentne magnitude Mw koju su za odabrane potrese javile svjetske i regionalne agencije. Odabrana je tzv. Yorkova regresija koja je prikladna u slučaju da su mjerne pogreške prisutne kod obje varijable. Najbolju prilagodbu postiže se relacijom MwL = (–0,106 ± 0,122) + (1,002 ± 0,027) ML,CR (uz koeficijent determinacije R2 = 0,90). Odabrani potresi dogodili su se u Hrvatskoj i susjednim područjima, a imali su lokalne magnitude između 3,5 i 6,5. Analiza odstupanja ukazuje na mogućnost da se u katalogu početkom 1980-ih dogodio umjetni pozitivni skok u magnitudi ML,CR od ne više od 0,3 jedinice magnitude. Do njega je vjerojatno došlo pri zamjeni Wiechertovih seizmografa elektromagnetskima bez adekvatne korekcije magnitudne formule. Nagib pravca regresije vrlo blizak jedinici ukazuje da je prosječni omjer kraće i dulje stranice uzročnih rasjeda oko 1/2.

Defining rainfall intensity clusters in Turkey by using the fuzzy c-means algorithm [Elektronička građa] / Utku Zeybekoğlu, Asli Ülke Keskin. - Graf. prikazi.
Bibliografija: str. 192-194. - Summary ; Sažetak. - Turkey has seven traditionally accepted climatic zones that are defined primarily by maritime and topographic influences. Across these zones, the annual amount of rainfall, including its intensity and its seasonal distribution, vary considerably. These variations, which impact on both urban and rural communities, including the occurrence of water shortages and flash flooding events, are increasing in both frequency and magnitude due to global warming and climate change. Several types of climate occur in Turkey where climate zones have been defined with various methodologies. To better understand rainfall intensity patterns across Turkey, this study used the Fuzzy C-Means (FCM) algorithm to define their spatial distribution. In the first stage, the annual maximum rainfall intensity records for periods ranging from 30 to 78 years were obtained from 95 stations operated by the Turkish State Meteorological Service, and the longitude, latitude and altitude data for the stations were compiled for cluster analysis. Secondly, all rainfall intensities and geographical values were normalized, and in the third stage, the FCM algorithm was applied. The comparison of annual maximum rainfall intensities revealed five clusters. Four clusters were identified as discrete zones and one was identified as a transitional zone. Weather stations located in different geographical regions sometimes fell into the same clusters. In other words, rainfall events of similar intensity can occur in different climatic zones. This study, which brought a different perspective to clustering studies, showed that rainfall intensity values can be successfully analyzed at a national scale with the FCM technique. - Turska ima sedam tradicionalno prihvaćenih klimatskih zona koje su definirane prvenstveno maritimnim i topografskim utjecajima. Diljem tih zona godišnja količina oborine, uključujući njezin intenzitet i sezonsku razdiobu, znatno se razlikuje. Te varijacije, koje utječu i na urbane i na ruralne ljudske zajednice, uključujući pojavu nestašice vode i poplave, povećavaju se i u učestalosti i magnitudi zbog globalnog zatopljenja i klimatskih promjena. U Turskoj se pojavljuje nekoliko tipova klime, pri čemu su klimatske zone definirane različitim metodologijama. Kako bi bolje razumjeli obrasce intenziteta oborine diljem Turske, u ovoj studiji korišten je algoritam „neizrazitih klasterskih srednjaka“ („fuzzy c-means“ – FCM) s ciljem definiranja njihove prostorne razdiobe. U prvom koraku, korišteni su zapisi godišnjih maksimalnih intenziteta oborine za razdoblja u rasponu od 30 do 78 godina s 95 postaja kojima upravlja Turska državna meteorološka služba, a podaci o zemljopisnoj dužini, zemljopisnoj širini i nadmorskoj visini postaja dodani su radi analize klastera. U drugom koraku normalizirani su svi intenziteti oborine i zemljopisni podaci, a u trećem je primijenjen FCM algoritam. Usporedba godišnjih maksimalnih intenziteta oborine definirala je postoojanje pet klastera. Četiri klastera identificirana su kao diskretne zone, a jedan je identificiran kao prijelazna zona. Meteorološke postaje koje pripadaju različitim zemljopisnim područjima ponekad pripadaju istom klasteru. Drugim riječima, oborinski događaji sličnog intenziteta mogu se pojaviti u različitim klimatskim zonama. Ova studija pokazala je da se vrijednosti intenziteta oborine na nacionalnoj razini mogu uspješno analizirati FCM tehnikom, doprinoseći drukčijem pogledu na studije koje koriste analizu klastera.

Different effects of latent heat in planetary boundary layer and cloud microphysical processes on Typhoon Sarika (2016) [Elektronička građa] / Jiangnan Li, Chenghui Ding, Fangzhou Li, Wenshi Lin, Youlong Chen. - Graf. prikazi.
Bibliografija: str. 62-65. - Summary ; Sažetak. - Three simulation experiments were conducted on Typhoon (TC) “Sarika” (2016) using the WRF model, different effects of the latent heat in planetary boundary layer and cloud microphysical process on the TC were investigated. The control experiment well simulated the changes in TC track and intensity. The latent heat in planetary boundary layer or cloud microphysics process can affect the TC track and moving speed. Latent heat affects the TC strength by affecting the TC structure. Compared with the CTL experiment, both the NBL experiment and the NMP experiment show weakening in dynamics and thermodynamics characteristics of TC. Without the effect of latent heat, the TC cannot develop upwards and thus weakens in its intensity and reduces in precipitation; this weakening effect appears to be more obvious in the case of closing the latent heat in planetary boundary layer. The latent heat in planetary boundary layer mainly influences the generation and development of TC during the beginning stage, whereas the latent heat in cloud microphysical process is conducive to the strengthen and maintenance of TC in the mature stage. The latent heat energy of the cloud microphysical process in the TC core region is an order of magnitude larger than the surface enthalpy. But the latent heat release of cloud microphysical processes is not the most critical factor for TC enhancement, while the energy transfer of boundary layer processes is more important. - Kako bi se ispitali različiti utjecaji latentne topline u planetarnom graničnom sloju i mikrofizičkih procesa u oblacima, WRF modelom su provedena tri eksperimenta za tajfun (TC) “Sarika” (2016). Kontrolnim eksperimentom dobro su simulirane promjene intenziteta i putanja TC-a. Latentna toplina u planetarnom graničnom sloju te mikrofizički procesi u oblacima mogu utjecati na putanju TC i na brzinu njegovog gibanja. Latentna toplina utječe na jačinu TC-a putem promjene strukture TC-a. U usporedbi s CTL eksperimentom i NBL i NMP eksperiment ukazuju na slabljenje dinamike i termodinamičkih svojstava TC-a. Bez utjecaja latentne topline TC se ne može vertikalno razvijati i stoga mu intenzitet slabi, a količina oborine se reducira; to slabljenje je očitije u slučaju kada je latentna toplina ograničena na planetarni granični sloj. Latentna toplina u planetarnom graničnom sloju uglavnom utječe na stvaranje i razvoj TC-a u početnoj fazi, dok latentna toplina vezana za mikrofizičke procese u oblaku pogoduje jačanju i održavanju njegove zrele faze. Latentna toplina mikrofizičkih procesa u oblakcima u jezgri TC-a je za red veličine veća od prizemne entalpije. Međutim, oslobađanje latentne topline pri mikrofizičkim procesima u oblacima nije najvažnije za jačanje TC-a, već je za njegovo jačanje važniji transfer energije u procesima planetarnog graničnog sloja.

Flood hazard assessment of a flood-prone intensively urbanized area [Elektronička građa] : a case study from Samsun Province, Turkey / Neslihan Beden, Aslı Ülke Keskin. - Ilustr., graf. prikazi.
Bibliografija: str. 22-24. - Summary ; Sažetak. - Flooding is one of the most catastrophic events among the wide spectrum of natural disasters that impact human communities. The identification of floodprone areas and the probability of occurrence, or estimated return period, of flood events are fundamental to proper planning for flood management and minimization of the social and economic costs of flood damage. In this study, 1D/2D coupled flood models of the Mert River, which flows into the Black Sea at Samsun in north-central Turkey, were developed. Based on the flood modeling results, flood extent, flood depth and flood hazard maps for the river were produced and they showed that the study area is particularly flood prone, as evidenced by catastrophic flooding in 2012. Specifically, the estimated 100, 500 and 1000-year peak discharges would affect 184 ha, 262 ha and 304 ha, respectively, of the 1,200 ha study area. Hazard ratings for the areas expected to be affected are shown in the flood hazard maps generated. The results of this research can be used by local government agencies in Samsun for the development of policies, strategies and actions that would help minimize the social and economic impacts of flooding, especially adjacent to the downstream sections where there is intensive development on the flood plain. - Poplava je jedan od najkatastrofalnijih događaja među širokim spektrom prirodnih katastrofa koje utječu na ljudske zajednice. Identifikacija poplavno podložnih područja i vjerojatnost nastanka poplava ili procjena razdoblja povratka od suštinskog su značaja za pravilno planiranje upravljanja poplavama i minimiziranje socijalnih i ekonomskih troškova štete od poplave. U ovoj studiji razvijeni su 1D/2D modeli poplava rijeke Mert, koja se uliva u Crno more kod Samsuna na sjeveru središnje Turske. Na temelju rezultata modeliranja poplava, izrađeni su obim poplava, dubina poplave i opasnosti od poplave za rijeku te su pokazali da je proučavano područje posebno podložno poplavi, o čemu svjedoče katastrofalne poplave u 2012. Točnije, procijenjeni 100-, 500- i 1000-godišnji vršni ispusti utjecali bi na 184 ha, 262 ha i 304 ha na studijskoj površini od 1200 ha. Ocjene opasnosti za područja na koja se očekuje da će biti pogođene prikazane su u generiranim kartama opasnosti od poplave. Rezultate ovog istraživanja mogu koristiti lokalne samouprave u Samsunu za razvoj politika, strategija i radnji koje će pomoći umanjivanju socijalnih i ekonomskih učinaka poplava, posebno susjednih dijelova nizvodno gdje je intenzivni razvoj na poplavnoj površini.

Internal seiches in a karstic mesotrophic lake (Prošće, Plitvice Lakes, Croatia) [Elektronička građa] / Zvjezdana B. Klaić, Karmen Babić, Tomislav Mareković. - Ilustr., graf. prikazi.
Bibliografija: str. 175-177. - Summary ; Sažetak. - A lake temperature experiment was performed at the Prošće, Plitvice Lakes, Croatia during a 4-month observational period (6 July–4 November, 2019) to investigate the occurrence and characteristics of internal seiches in the lake. Two-minute mean lake temperatures were measured at a single lake point at fifteen depths ranging from 0.2 to 27 m. Analysis of these data provided insight into the previously unknown and rather complex Prošće Lake seiching. Power spectral densities (PSDs) and magnitude-squared coherences (γ2), together with corresponding cross-spectrum phases that were obtained from the hourly mean lake temperature, air pressure and wind speed data, suggested the presence of three vertical modes of an internal seiche. The first mode (V1H1, period of 6.09 h) corresponds to free baroclinic oscillations; the second mode (V2H1, period of 11.64 h) and the third mode (V3H1, period of 25.60 h) are associated with forced baroclinic oscillations of the lake interior. Excitation of the higher vertical modes is attributed to the influence of dense tributary water. Due to this water influence, vertical temperature gradients in the lake interior were relatively weak; consequently, a single thick metalimnion and/or two metalimnetic layers were established, which resulted in the presence of the V2H1 and V3H1 modes, respectively. Additionally, due to the influence of tributary water, the lake did not attain the typical stratification that is characterized by hypolimnetic temperatures of ≈ 4°C. Instead, during the entire observational period, the hypolimnetic temperatures were consistently above 7.6 °C. - Tijekom 4-mjesečnog razdoblja (od 6. srpnja do 4. studenog 2019.) proveden je eksperiment mjerenja temperature jezera kako bi se ispitala pojava i osobine unutarnjih stojnih valova u Prošćanskom jezeru (Plitvička jezera, Hrvatska). Dvominutni srednjaci temperature mjereni su u jednoj točki jezera na petnaest dubina u rasponu od 0,2 do 27 m. Analiza tih podataka ukazala je na do sada nepoznatu i prilično složenu strukturu unutarnjih stojnih valova u Prošćanskom jezeru. Spektralne gustoće snage (PSD) i kvadrati magnituda koherencije (γ2) te pripadne kros-spektralne faze koje su izračunate iz srednjih satnih temperature jezera i tlaka zraka te brzina vjetra ukazale su na prisustvo tri vertikalna moda unutarnjih stojnih valova. Prvi mod (V1H1, period od 6,09 h) odgovara slobodnim baroklinim oscilacijama, dok su drugi (V2H1, period od 11,64 h) i treći mod (V3H1, period od 25,60 h) povezani s prisilnim baroklinim oscilacijama unutrašnjosti jezera. Pobuđivanje viših vertikalnih modova pripisano je utjecaju guste vode pritoka. Zbog utjecaja te vode vertikalni temperaturni gradijenti u unutrašnjosti jezera bili su relativno mali te se u skldu s tim formirao jedan debeo metalinij ili dva zasebna metalimnija. U skladu s tim pojavljivali su se modovi V2H1, odnosno V3H1. Nadalje, jezero zbog utjecaja vode pritoka nije postiglo tipičnu stratifikaciju pri kojoj su temperature u hipolimniju ≈ 4 °C. Umjesto toga tijekom cijelog promatranog razdoblja temperature u hipolimniju su neprekidno bile iznad 7.6 °C.

Multivariable teaching-learning-based optimization (MTLBO) algorithm for estimating the structural parameters of the buried mass by magnetic data [Elektronička građa] / Ata Eshaghzadeh, Sanaz Seyedi Sahebari. - Graf. prikazi.
Bibliografija: str. 231-234. - Summary ; Sažetak. - This paper presents a nature-based algorithm, titled multivariable teaching-learning-based optimization (MTLBO) algorithm. MTLBO algorithm during an iterative process can estimates the best values of the buried structure (model) parameters in a multi-objective problem. The algorithm works in two computational phases: the teacher phase and the learner phase. The major purpose of the MTLBO algorithm is to modify the value of the learners and thus, improving the value of the model parameters which leads to the optimal solution. The variables of each learner (model) are the depth (z), amplitude coefficient (k), shape factor (q), angle of effective magnetization (θ) and axis location (x0) parameters. We employ MTLBO method for the magnetic anomalies caused by the buried structures with a simple geometric shape such as sphere and horizontal cylinder. The efficiency of the MTLBO is also studied by noise corruption synthetic data, as the acceptable results were obtained. We have applied the MTLBO for the interpretation of the four magnetic anomaly profiles from Iran, Brazil and India. - U ovom radu je predstavljen prirodno utemeljen multivarijabilni algoritam optimizacije poučavanjem-učenjem (MTLBO). MTLBO algoritam tijekom iterativnog postupka može procijeniti najbolje vrijednosti parametara podzemnih struktura (model) u višepredmetnom problemu. Algoritam djeluje u dvije računske faze: fazi učitelja i fazi učenika. Glavna svrha algoritma MTLBO je mijenjati naučene vrijednosti te poboljšavajući tako vrijednosti parametara modela dovesti do optimalnog rješenja. Varijable svakog učenika (model) su: dubina (z), koeficijent amplitude (k), faktor oblika (q), kut učinkovite magnetizacije (θ) i parametri osi (x0). U radu je korištena MTLBO metoda na podacima magnetskih anomalija uzrokovanih podzemnim strukturama jednostavnog geometrijskog oblika, poput sfere i vodoravno postavljenog cilindra. Učinkovitost MTLBO metode također je proučavana na šumom kontaminiranim sintetičkim podacima, budući da su dobiveni prihvatljivi rezultati. MTLBO metoda je primijenjena za interpretaciju četiri profila magnetske anomalije u Iranu, Brazilu i Indiji.

Obtaining the Manning roughness with terrestrialremote sensing technique and flood modeling using FLO-2D [Elektronička građa] : a case study Samsun from Turkey / Vahdettin Demir, Asli Ülke Keskin. - Ilustr., graf. prikazi.
Bibliografija: str. 153-155. - Summary ; Sažetak. - Determining the Manning roughness coefficients is one of the most important steps in flood modeling. The roughness coefficients cause differences in flood areas, water levels, and velocities in the process of modeling. This study aims to determine both the Manning roughness coefficient in the river sections and outside of the river regions by using the Cowan method and remote sensing technique in the flood modeling. In the flood modeling, FLO-2D Pro program which can simulate flood propagation in two dimensions was utilized. Mert River in Samsun province located in the northern part of Turkey was chosen as the study area. Samples taken from the river were subjected to sieve analysis, the types of constituent material were determined according to the median diameters and the roughness coefficients were obtained using the Cowan method. For regions outside of the river were applied the maximum likelihood method being one of the controlled classification methods. Manning roughness values were assigned the classified image sections. Remote sensing techniques were meticulously employed to achieve time management in areas outside the river and a new approach was proposed in the Manning assessment of flood areas to ensure uniformity in the study area. In the classification made using the maximum likelihood method, the overall classification accuracy was 92.9% and the kappa ratio “κ” was 90.64%. The results were calibrated with the last hazardous flood images in 2012 and HEC-RAS 2D program, another flood modeling program. - Određivanje Manningovih koeficijenata hrapavosti jedan je od najvažnijih koraka u modeliranju poplava. Koeficijenti hrapavosti u procesu modeliranja uzrokuju razlike u poplavnim područjima, razinama vode i brzinama. Cilj ove studije je utvrditi koeficijent hrapavosti u riječnim odsječcima te i izvan riječnih područja korištenjem Cowanove metode i tehnike daljinskog istraživanja. U modeliranju poplave korišten je program FLO-2D Pro koji može simulirati širenje poplave u dvije dimenzije. Za područje istraživanja odabrana je rijeka Mert u provinciji Samsun koja se nalazi u sjevernom dijelu Turske. Uzorci uzeti iz rijeke analizirani su pomoću sita, gdje su vrste sastavnog materijala određene prema srednjim promjerima, a koeficijenti hrapavosti dobiveni su Cowanovom metodom. Za područja izvan rijeke primijenjena je metoda najveće vjerojatnosti koja je jedna od kontroliranih metoda klasifikacije. Manningove vrijednosti hrapavosti dodijeljene su klasificiranim odsječcima slike. Tehnike daljinskih mjerenja pomno su korištene kako bi se procijenili koeficijenti hrapavosti u područjima izvan rijeke, a novi je pristup predložen u Manningovoj procjeni poplavnih područja kako bi se osigurala ujednačenost na istraživanom području. U klasifikaciji izvedenoj metodom najveće vjerojatnosti, ukupna točnost klasifikacije bila je 92,9%, a kappa omjer “κ” 90,64%. Rezultati su kalibrirani prema posljednjim slikama opasnih poplava 2012. godine i HEC-RAS 2D programom, koji je također program za modeliranje poplave.

The role of paleolimnology in climate and environment reconstruction and lake restoration in light of research on selected bioindicators [Elektronička građa] / Marta Wojewódka, Dario Hruševar. - Graf. prikazi.
Bibliografija: 81 jed. - Summary. - Paleolimnologists and ecologists study biotic and abiotic variables to track long-term and short-term environment changes. Microscopic invertebrates, phytoplankton of freshwater ecosystems, and pollen grains have been extensively studied during the last decades. Surveys of modern and fossil biota composition might provide information about past changes caused by climate alteration and human activity. Furthermore, research on the modern population of these biological proxies may be utilized to assess environmental quality and restoration measures. This paper synthesizes knowledge of the use of selected microscopic invertebrates (Cladocera, Copepoda, Ostracoda, Rotifera), phytoplankton, and pollen grains for the aforementioned issues. This review shows that the ability of these biological proxies to indicate environment changes is versatile. Some of them may be utilized to track long-term changes of temperature (pollen) or pH (Diatomeae). Others are useful to reconstruct paleosalinity (Ostracoda) or conductivity (Ostracoda, Diatomeae), while the utilization of Rotifera and Copepoda in paleoreconstruction, due to the very poor preservation of the remains, is very limited, although these fauna are very useful for assessing modern water quality.

Source of groundwater iron and manganese in Chandrapur district, central India [Elektronička građa] / Rahul Krishna Kamble. - Graf. prikazi.
Bibliografija: 58 jed. - Summary. - Groundwater sampling was carried out by grab sampling method from 36 sampling locations from the Chandrapur district in three seasons i.e. winter, summer, and post-monsoon. The samples were analysed for physicochemical parameters and heavy metals i.e. iron and manganese. Data obtained from the study area was interpreted by using multivariate statistical analysis i.e. principal component analysis, cluster analysis, correlation matrix and one way ANOVA to ascertain source apportionment of these two heavy metals. The results of the multivariate analysis revealed that iron and manganese both were associated with the lithogenic source. Groundwater irons concentration was higher when compared with manganese and at a number of sampling locations it was above the stipulated standard of BIS (Bureau of Indian Standards) (0.3 mg/L).

Water quality of the Trstionica River (Bosnia and Herzegovina) [Elektronička građa] / Šuhreta Delibašić, Jasna Huremović, Sabina Žero, Sabina Gojak-Salimović. - Ilustr., graf. prikazi.
Bibliografija: 17 jed. - Summary ; Sažetak. - The present study was conducted to investigate the water quality of the Trstionica River, Bosnia and Herzegovina. The physicochemical properties (temperature, pH, conductivity, total solids after evaporation at 105 °C), content of metals (calcium (Ca), cadmium (Cd), chromium (Cr), copper (Cu), iron (Fe), magnesium (Mg), manganese (Mn), sodium (Na), nickel (Ni), lead (Pb) and zinc (Zn)), and anions (chloride (Cl–), and phosphate (PO43–)) were determined in water samples collected at seven locations during two sampling periods: unstable weather conditions (precipitation), and stable weather conditions (without precipitation). There was a significant difference in the content of individual parameters in the river water depending on the sampling time. For determination of metals concentrations, which were below the limit of detection, a preconcentration method using an ion-exchange resin was applied. The metals concentrations during the rainy day were in the order Ca >Mg >Na >Fe >Cu >Zn >Pb >Mn with mean values of 343, 6.03, 1.94, 0.18, 0.20, 0.03, 0.02, 0.01 mg dm–3, respectively, and during stable weather conditions: Ca >Mg >Na >Cu >Fe >Mn >Zn with mean values of 288, 7.62, 2.38, 0.11, 0.10, 0.01, 0.01 mg dm–3, respectively. Cd, Cr, and Ni concentrations were below limit of detection in both cases. Obtained values were compared with World Health Organization (WHO) regulations. The results showed that the Trstionica River in the investigated part of the stream meets most of the parameters required by the regulations. The correlation between analysed parameters was assessed, as well. Based on the calculated water quality index values, the water of Trstionica River falls into the category of excellent water. - Ova je studija provedena kako bi se istražila kvaliteta vode rijeke Trstionice, Bosna i Hercegovina. Fizikalno-kemijska svojstva (temperatura, pH, vodljivost, ukupna kruta tvar nakon isparavanja pri 105 °C), sadržaj metala (Ca, Cd, Cr, Cu, Fe, Mg, Mn, Na, Ni, Pb i Zn) i aniona (kloridi i fosfati) određeni su u uzorcima vode prikupljenim na sedam lokacija tijekom dva razdoblja uzorkovanja: nestabilni vremenski uvjeti (oborine) i stabilni vremenski uvjeti (bez oborina). Došlo je do značajne razlike u sadržaju pojedinih parametara u riječnoj vodi, ovisno o vremenu uzorkovanja. U slučaju metala, čije su koncentracije bile ispod granice detekcije primijenjene metode (FAAS), primijenjena je metoda predkoncentracije upotrebom ionsko-izmjenjivačke smole. Koncentracije metala tijekom kišnog dana bile su u redoslijedu Ca >Mg >Na >Fe >Cu >Zn >>Pb >Mn sa srednjim vrijednostima 343, 6,03, 1,94, 0,18, 0,20, 0,03, 0,02, 0,01 mg dm–3, odnosno za vrijeme stabilnih vremenskih uvjeta: Ca >Mg >Na >Cu >Fe >Mn >Zn sa srednjim vrijednostima od 288, 7,62, 2,38, 0,11, 0,10, 0,01, 0,01 mg dm–3. Koncentracije Cd, Cr i Ni su bile ispod granice detekcije primijenjene metode u oba slučaja. Dobivene vrijednosti uspoređene su s propisima Svjetske zdravstvene organizacije. Rezultati su pokazali da rijeka Trstionica u istraživanom dijelu toka ispunjava većinu parametara propisanih legislativom. Također su procijenjene korelacije između analiziranih parametara. Na temelju izračunatih vrijednosti indeksa kakvoće vode, Rijeka Trstionica spada u kategoriju izvrsne vode.

3D cell technology in biomedical research [Elektronička građa] / Katarina Mišković Špoljarić, Marijana Jukić, Teuta Opačak-Bernardi, Ljubica Glavaš-Obrovac. - Ilustr.
Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - Traditional two dimensional cell culture has enabled great strides in biomedicine but needs to be improved to be able to keep up with the demands of modern biomedical research. 2D monolayer culture cannot replicate tissue responses and needs to be supplemented with extensive animal research. Growing cells in three dimensional scaffolds provides a more functional model for biomedical research than traditional monolayer culture. Depending on the needs and the complexity of the model there are several ways that 3D models can be initiated. Simple spheroids can be grown in low adherence plates and in hanging drops while larger spheroids and co-cultured ones need to be grown in systems with greater support such as hydro gels. The system that offers the greatest flexibility is the magnetic levitation approach. In the paper we offer a brief resume to various 3D methods and their characteristics to ease the choice of methods for implementing 3D cell culture techniques. - Klasična dvodimenzionalna stanična kultura omogućila je veliki napredak u biomedicini, ali potrebno ju je unaprijediti kako bi odgovorila zahtjevima modernih biomedicinskih istraživanja. Monoslojna 2D kultura ne može replicirati tkivni odgovor i potrebno ju je nadopuniti iscrpnim istraživanjima na životinjama. Uzgoj stanica u trodimenzionalnim potpornim sustavima rezultira funkcionalnijim biomedicinskim modelima u odnosu na klasične monoslojne kulture. U ovisnosti o potrebama i složenosti istraživanja, 3D modeli se mogu formirati na nekoliko načina. Jednostavni sferoidi se mogu uzgojiti kao viseća kap te na slabo adherirajućim površinama dok se veliki sferoidi i ko-kulture uzgajaju u jačim sustavima podrške poput hidrogelova. Magnetska levitacija je jedan od načina pripreme koji omogućuje najveću fleksibilnost u uzgoju sferoida. U radu ćemo ponuditi kratki pregled različitih 3D modela i njihovih karakteristika kako bismo olakšali odabir metode kod uspostave 3D kulture.

A cross sectional study was conducted to explore the age-related variations among different anthropometric and body composition characteristics amongst the adult Kheria Sabar males of Purulia district of West Bengal. From fifteen villages, 304 apparently healthy adult males aged 18–60 years were selected at random. Subjects were categorized into four age groups and standard anthropometric measurements were used like height (HT), weight (WT), mid-upper-arm circumference (MUAC) and skinfolds of biceps (BSF), triceps (TSF) and sub-scapular (SSSF) region. Derived variables of body mass index (BMI), per cent body fat (PBF), fat mass (FM), fat-free mass (FFM), fat mass index (FMI) and fat-free mass index (FFMI) were also calculated. Majority of the variables were found to be inversely correlated with age. Positive (HT, WT, MUAC, BMI, FFM and FFMI) and negative (FM and FMI) significant differences were observed across different age groups. It was also observed that the frequency of undernutrition (62.6%) was the highest among the elderly people with 47.6% overall prevalence. This study clearly indicates that among the undernourished individuals, older people were more vulnerable to malnutrition and thus immediate nutritional intervention is required. - Pothranjenost i starenje mogu znatno utjecati na sastav tijela. Cilj ove transverzalne studije je istraživanje dobnih varijacija u antropometrijskim vrijednostima i sastavu tijela u muškoj populaciji Kheria Sabar iz pokrajine Purulia u Zapadnom Bengalu u Indiji.. Slučajni uzorak uključio je 304 zdrava, odrasla muškarca u dobi između 16 i 80 godina iz 15 sela u pokrajini, koji su podijeljeni u četiri dobne skupine. Prikupljene su standarne antropometrijske mjere: visina (HT), težina (WT), opseg nadlaktice (MUAC) i kožni nabori bicepsa (BSF), tricepsa (TSF) i na leđima (SSSF). Izračunate su varijable indeksa tjelesne mase (BMI) i postotka masnog tkiva (PBF) te masna tjelesna masa (FM) i nemasna tjelesna masa (FFM) i odgovarajući indeksi (FMI i FFMI). Većina varijabli bila je u negativnoj korelaciji sa dobi. Utvrđene su statistički značajne pozitivne (HT, WT, MUAC, BMI, FFM and FFMI) i negativne (FM and FMI) razlike između dobnih skupina. Ukupna prevalencija pothranjenosti iznosila je 47,6%, a najviša je bila u najstarijoj dobnoj skupini (62,6%). Rad jasno pokazuje da je rizik od malnutricije najveći u starijoj populaciji i da je u tom smislu potrebno poduzeti intervencijske mjere.

Comparison of self-reported and measured height, weight and BMI in Turkish university students [Elektronička građa] / Sercan Acar, Ayşegül Özdemir, Cansev Meşe Yavuz, Seçil Sağır, Mehmet Sağır, Başak Koca Özer. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - Accuracy and validity of self-reported height and weight, and body image satisfaction have not been evaluated particularly in young adult population in Turkey. The aim of the study was to establish the differences of self-reported height and weight, and body mass index (BMI). The study conducted on 617 university students (304 males and 313 females) aged 17-30 years from Ankara and Sivas, Turkey. Height and weight were measured and obtained by a questionnaire. From both measured and self-reported values for accuracy absolute differences were calculated. BMI was calculated from both self-reported and measured height and weight values using World Health Organization (WHO) cut-offs. The results showed that mean accuracy for the overestimated height was 1.83 cm for males (Ankara 1.59 cm and Sivas 2.05 cm), and 2.42 cm for females (Ankara 2.12 cm and Sivas 2.74 cm), and underreporting weight was 0.35 kg (Ankara 0.13 kg and Sivas 0.56 kg) and -0.95 kg (Ankara 0.33 kg and Sivas 1.07 kg), respectively. Self-reported BMIs>25 was 33.9% for males (Ankara 27.6% and Sivas 39.6%), and 15.7% for females (Ankara 9.9% and Sivas 16.8%), while measured BMIs>25 was 38.2% (Ankara 30.3% and Sivas 45.3%) and 25.9% (Ankara 21.7% and Sivas 35.5%), respectively. In conclusion, study group tended to overestimate height but underestimate weight, therefore the self-reported weight and height studies needed to evaluate more cautiously, and direct measurements or correction equations for adjustment needed for reliable results. - Preciznost i valjanost samoprocijenjenih vrijednosti visine, težine i zadovoljstva tijelom nisu do sada dovoljno istraživani u mlađoj populaciji u Turskoj. Cilj rada je utvrditi razlike između samoprocijenjenih i izmjerenih vrijednosti visine, težine i indeksa tjelesne mase (BMI). Istraživanje je provedeno na 617 ispitanika (304 studenta i 313 studentice) u dobi između 17 i 30 godina u Ankari i Sivasu u Turskoj. Vrijednosti visine i težine su izmjerene i prikupljene upitnikom. Na temelju obje vrste podataka izračunate su vrijednosti BMI prema klasifikaciji Svjetske zdravstvene organizacije. Rezultati pokazuju višu samoprocijenjenu srednju vrijednost visine za 1,83 cm u muškaraca (Ankara 1,59 cm; Sivas 2.05 cm), i za 2,42 cm u žena (Ankara 2,12 cm; Sivas 2,74 cm) i nižu srednju vrijednost težine za 0,35 kg u muškaraca (Ankara 0,13 kg i Sivas 0,56 kg) te za 0,95 kg u žena (Ankara 0,33 kg; Sivas 1,07 kg). Samoprocijenjeni BMI >25 je utvrđen u 33,9% muškaraca (Ankara 27,6%; Sivas 39,6%) te 15,7% žena (Ankara 9,9%; Sivas 16,8%), a izmjereni BMI >25 u 38,2% muškaraca (Ankara 30,3%; Sivas 45,3%) i u 25,9% žena (Ankara 21,7%; Sivas 35,5%). Općenito uzevši, ispitanici su percipirali više vrijednosti visine i manje vrijednosti težine od onih stvarnih što ukazuje na potrebu kritičkog korištenja samoprocijenjenih podataka i oslanjanja na izravna mjerenja ili statističku prilagodbu samoprocijenjenih podataka kako bi se dobili pouzdani rezultati.

Daily calorie intake, level of physical activity and morphological status of children and adolescents in three cities of Russian Federation [Elektronička građa] / Ekaterina Yu. Permiakova, Olga A. Gilyarova, Elena Z. Godina. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - The study is devoted to identifying the intergroup variability of morphological characteristics, body composition, in-dicators of physical activity and nutritional status in modern adolescents of the cities of Elista, Arkhangelsk and Moscow. The increased body weight of Arkhangelsk adolescents of both sexes determines the high values of basal metabolic rates in this group. At the same time, a low level of physical activity has a negative effect on the development of the musculo-skeletal component, that is, increased body weight values are associated in this group to a greater extent with its fat component. Residents of Moscow have intermediate values among the three groups surveyed for most morphological in-dicators and minimum indicators of exchange. However, it is this group that is characterized by the maximum amount of time allocated to physical activity. The results obtained indirectly indicate the presence of a certain level of socio-eco-nomic differences in the surveyed cities. - Prikazano istraživanje usmjereno je na određivanje varijabilnosti u morfološkim obilježjima, sastavu tijela, fizičkoj aktivnosti i prehrambenom statusu među skupinama današnjih adolescenata iz gradova Elista, Arhangelsk i Moskva. Povećana težina tijela uvjetuje visoke vrijednosti bazalnog metabolizma adolescenata u Arhangelsku. Istodobno, niska razina fizičke aktivnosti negativno utječe na razvoj mišića i kostiju u toj skupini, tj. povećana tjelesna težina povezana je kod njih s s većim postotkom masnog tkiva. Adolescenti iz Moskve pokazuju srednje vrijednosti u odnosu na druge dvije ispitivane skupine za većinu ispitivanih morfoloških obilježja. Međutim, upravo ta skupina posvećuje najviše vremena fizičkoj aktivnosti. Dobiveni rezultati neizravno ukazuju na postojanje određenih socio-ekonomskih razlika među ispitivanim skupinama adolescenata.

Gender and regional differences in body image dissatisfaction in modern university students [Elektronička građa] : a pilot study in two cities of Eastern Europe / Elena Z. Godina, Irina M. Sineva, Ainur A. Khafizova, Rostislav V. Okushko, Marina A. Negasheva. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - Complex anthropological and psychological study of the university students was carried out in two regions (the cities of Moscow and Tiraspol) with the aim to reveal gender and regional differences of body image dissatisfaction and their connection with the body build. 502 individuals (187 males and 315 females) aged from 17 to 25 years were investigated. The program included anthropometric measurements (height and weight, with further calculation of Body Mass Index – BMI), evaluation of body mass components, as well as psychological testing with Stunkard’s silhouette scale and the Situational Inventory of Body-Image Dysphoria (SIBID). It was found that among the representatives of both sexes the level of dissatisfaction with their own body is relatively similar (69% of males and 67% of females). However the girls were mostly dissatisfied with their excessive, as they perceived, body mass (83% of the total number of dissatisfied individuals) while the boys were dissatisfied mostly because of their underweight (60% of the total number of dissatisfied individuals). Besides, the girls were more likely to exaggerate their weight while the boys perceived it as smaller than it really was. In girls certain social influences had more impact on body image dissatisfaction than in boys. Among the girls studied, the Muscovites were more critical to their own physical appearance, which resulted in lower self-assessment of their body image and, consequently, in less positive influence of this assessment on the quality of life compared to the girls from Tiraspol. - Složeno antropološko i psihološko istraživanje među studentima sveučilišta provedeno je u dvije regije (gradovi Moskva i Tiraspol) s ciljem utvrđivanja spolnih i regionalnih razlika u nezadovoljstvu tijelom i njihove povezanosti s tjelesnim statusom. Ispitana su 502 studenta (187 muškaraca i 315 žena) u dobi od 17 do 25 godina. Program je uključivao antropometrijska mjerenja (visina i težina, uz daljnji izračun indeksa tjelesne mase ― BMI), procjenu komponenata tjelesne mase, kao i psihološko testiranje sa Stunkardovom skalom percepcije tjelesnog izgleda i Situacijskim upitnikom disforije zbog tjelesnog izgleda (SIBID). Utvrđeno je da je u oba spola razina nezadovoljstva vlastitim tijelom relativno slična (69% muškaraca i 67% žena). Međutim, djevojke su uglavnom bile nezadovoljne prekomjernom tjelesnom masom (83% od ukupnog broja nezadovoljnih ispitanica), dok su mladići bili nezadovoljni uglavnom zbog nedostatne težine (60% od ukupnog broja nezadovoljnih ispitanika). Osim toga, djevojke su češće preuveličavale svoju težinu, dok su je mladići doživljavali manjom nego što stvarno jest. U djevojaka su određeni društveni utjecaji imali više utjecaja na nezadovoljstvo vlastitom slikom tijela nego u dječaka. Među proučavanim djevojkama, Moskovljanke su bile kritičnije prema vlastitom fizičkom izgledu, što je rezultiralo nižom samoprocjenom slike tijela i posljedično negativnijim utjecajem ove procjene na kvalitetu života u usporedbi s djevojkama iz Tiraspola.

Harmonic structure of tracheal biometrics [Elektronička građa] / Dinko Milavec, Jelenko Lazić, Hrvoje Puretić, Vlatko Mićković, Goran Sirovatka, Zoran Lončar. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - According to existing research, in 20% of patients the required tracheal size (diameter and length) could not be measured automatically (using software solution). In this paper, we use Zederbauer's harmonic circle to define the relationship between a person's body height and the diameter and length of their trachea. We then explore differences by gender. The results show that there is a highly significant correlation between measured data and values obtained by harmonic analysis. The final goal is to obtain the mathematical interpretation of the relationship of the tracheal size to the height of man, in order to further apply such sizes in the creation of 3D models that could finally be printed on appropriate 3D printers and with the suitable material. - Istraživanja pokazuju da kod 20 % pacijenata nije moguće automatski softverskim programom izmjeriti potrebne veličine dušnika (promjer i duljina). U ovom radu pomoću Zederbauerove harmonijske kružnice definiramo odnos tjelesne visine čovjeka i promjera i duljine njegovog dušnika. Potom razlučujemo taj odnos prema spolu. Odredili smo i volumen dušnika kao važnu veličinu u matematičkom modelu. Konačni cilj i put kojim treba krenuti je matematičko definiranje odnosa dušnika prema visini čovjeka u cilju daljnje primjene takvih veličina u kreiranju 3D modela koji bi se konačno mogli isprintati na odgovarajućim printerima i u odgovarajućem materijalu, za potrebe biomehaničkog inžinjerstva, kirurgije i forenzike.

Model-based analysis of changes in the morphological characteristics of Moscow students for the last two decades [Elektronička građa] / Marina A. Negasheva, Sofya N. Zimina, Irina M. Sineva, Elena Z. Godina. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - The aim of the paper is to develop a model of changes in morphological characteristics of young males and females body structure at the beginning of the 21st century. For this purpose the results of Moscow students’ annual screenings from 2000 to 2018 were analyzed (total number of 17–18-year-olds − 6,433 individuals). As a result, five factors describing the trends of changes were revealed and further analysis demonstrated variants of their values over time. An original model was developed, which reflected real morphological transformations in the body parameters of the young generation for the last 20 years. For both sex groups a trend towards macrosomia (gr. macros − big, soma- body) was revealed. For the boys some increase in linear traits was found with a decrease in muscularity. In girls, parabolic association between athletic characteristics and the year of investigation was found: the decrease in muscularity for the first decade, and its increase for the second one. - Cilj ovog rada je razvoj modela promjena u morfološkim obilježjima tjelesne strukture djevojaka i mladića na početku 21. stoljeća. U tu svrhu analizirani su rezultati godišnjih mjerenja moskovskih studenata od 2000. do 2018. godine (ukupno 6.433 osobe u dobi od 17–18 godina). Analizom je dobiveno pet faktora koji opisuju trendove promjena a daljnja analiza je pokazala varijabilnost vrijednosti tijekom vremena. Razvijen je originalan model koji odražava stvarne tjelesne morfološke promjene mlade generacije u posljednjih 20 godina. U oba spola uočen je trend makrosomije (grč. makrós: velik, sȏma: tijelo). U mladića opaženo je povećanje linearnih obilježja i smanjenje mišićnog tkiva. U djevojaka je utvrđena parabolična povezanost između atletskih karakteristika i godine ispitivanja: u prvom desetljeću došlo je do smanjenja mišićnog tkiva, a u drugom do njegovog povećanja.

Secular changes in male body height in the European part of Russia during the 20th century [Elektronička građa] / Lidia Lebedeva, Yulia Kucherova, Elena Godina. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - Significant political and economic transformations took place on the territory of contemporary Russia in the first part of the 20th century. We hypothesized that they would have affected male growth curve negatively. To test this idea, the dataset was collected to present the graph, which illustrates the changes in male body height during the 20th century. We searched for bibliographic sources with information about body height of men and women born during the 20th century, with full description of measurement methodology, sample design and significant geographical distribution of the dataset covering more than 15 territories of the country – cities or regions. Such criteria were met only for men. We found only 8 sources that could be considered reliable in the research. The observed graph confirms positive changes in male body height on the territory of the European part of contemporary Russia: for those, who were born in 1900‘s it was 166.1 cm, in 1920s – 166.5 cm, in 1940s – 171 cm, in 1960s – 174.8 cm and in 1980s the indicator reached 176.1 cm. No significant negative changes in this indicator have been found during the studied period. The primary hypothesis that political and socio-economic transformations affect male growth curve negatively was confirmed only partly. We concluded that unfavorable political and socio-economic events (such as revolutions, World War I and World War II, purges and famines) influenced the pace of body height increase in men. While the main period of secular trend was fixed in the first decades of the 20th century in Germany, Netherlands and France, in this part of Russia it occurred later, in 1930–1960s. However, the total increase in male height was very similar for all mentioned territories (9–11 cm) during 1900–1980’s. - Na prostoru suvremene Rusije u prvom dijelu 20. stoljeća dogodile su se značajne političke i ekonomske promjene. Naša je pretpostavka bila da su one negativno utjecale na krivulju rasta kod muškaraca. Za testiranje ove ideje, prikupljeni su podaci kako bi se izradio grafikon, koji ilustrira promjene u visini muškog tijela tijekom 20. stoljeća. Pretražili smo bibliografske izvore s podacima o tjelesnoj visini muškaraca i žena rođenih tijekom 20. stoljeća, s potpunim opisom mjerne metodologije, određivanja uzorka i značajnom geografskom raspodjelom podataka koji pokrivaju više od 15 teritorija zemlje – gradova ili regija. Takvi su kriteriji zadovoljeni su samo za muškarce. Pronašli smo samo 8 izvora koji bi se mogli smatrati pouzdanim u istraživanju. Dobiveni grafikon potvrđuje pozitivne promjene u visini muškog tijela na teritoriju europskog dijela suvremene Rusije: za one koji su rođeni 1900-ih to je bilo 166,1 cm, 1920-ih – 166,5 cm, 1940– ih – 171 cm, 1960-ih – 174,8 cm, a 1980-ih visina je dosegla 176,1 cm. U istraživanome razdoblju nisu utvrđene značajne negativne promjene ovog pokazatelja. Primarne hipoteze da političke i društveno-ekonomske transformacije negativno utječu na krivulju rasta muškaraca potvrđene su dijelom. Zaključili smo da nepovoljni politički i društveno-ekonomski događaji (poput revolucija, Prvog i Drugog svjetskog rata, čistki i gladi) utječu na tempo povećanja tjelesne visine kod muškaraca. Dok je glavno razdoblje sekularnog trenda bilo određeno u prvim desetljećima 20. stoljeća u Njemačkoj, Nizozemskoj i Francuskoj, na promatranom području Rusije nastupilo je kasnije, u 1930–1960-im. Međutim, ukupni porast muške visine bio je vrlo sličan za sva spomenuta područja (9–11 cm) u razdoblju od 1900–1980.

Usporedba dva komercijalna fiksativa pri upotrebi u rutinskim histološkim analizama [Elektronička građa] / Ljerka Armano, Romana Gračan. - Ilustr.
Bibliografske bilješke na kraju teksta. - Sažetak ; Summary. - Fiksiranje tkiva važan je korak u histološkoj obradi tkiva za izradu trajnih mikroskopskih preparata. Svrha fiksacije je očuvanje stanica i međustaničnih struktura kako bi što više nalikovali živom materijalu. U ovom istraživanju analizirali smo morfološke značajke unutrašnjih organa potočne pastrve (Salmo trutta L.) fiksirani s dva različita fiksativa. 10% neutralni puferirani formaldehid (PNF) koji daje kvalitetne histološke uzorke, ali je toksičan i kancerogen te zamjenskog fiksativa FineFix-a (FF) smanjene toksičnosti baziranog na etanolu. Kako bi usporedili učinak dva istraživana fiksativa, tkiva su nakon fiksacije uklopljena u paraplast, izrezana i obojena rutinskomn histološkom hemalaun eozinskom (HE) tehnikomte histokemijskom metodom bojenja perjodne kiseline i Schiffovog reagensa te alcijanskog modrila. Uzorci tkiva probavnog, dišnog i cirkulacijskog sustava potočne pastrvepokazalisu da je PNF i dalje najbolji izbor pri standardnoj fiksaciji za histološke i histokemijske analize. Kao najveća razlika između dva upotrebljena fiksativa ističe se kvaliteta fiksacije vezivnog tkiva u proučavanim organima, koja je bolja u tkivima fiksiranim s PNF, u usporedbi s FF, dok se FF istaknuo kao bolji fiksativ u HE bojenju preparata probavnog sustava. Ukoliko će se i dalje upotrebljavati PNF, određena osjetljiva tkiva poput probavnih organa mogu zahtijevati modificiranje standardnih postupaka bojenja, a naročito HE metode, kako bi se osigurao bolji afinitet tkiva za boju, a time i bolje prepoznavanje morfoloških struktura u tkivu, dok se potraga za zamjenskim, jednako kvalitetnim, fiksativom bez formalina i dalje nastavlja. - Tissue fixation is a very important step when preparing tissue for permanent histological samples. The purpose of fixation is to preserve cells and extracellular structures to resemble living material as much as possible. In this study we analysed morphological characteristics of major internal organs of the brown trout (Salmo trutta L.), after fixation with two different fixatives: 10% neutral buffered formaldehyde (NBF), which produces highquality histological samples, but is toxic and carcinogen and FineFix (FF) ethanol-based substitution for NBF with reduced toxicity. For proper comparison of studied fixatives, tissue samples were fixed, embedded in paraplast, sectioned and stained with routine hemalaun eosin (HE) technique and histochemical staining method for Periodic Acid – Schiff’s reaction combined with alcian blue. Based on the analysis of the tissue samples from the digestive, respiratory and circulatory system of the brown trout our results show that NBF is a better choice of fixation for histological and histochemical analyses. The major difference between the two fixatives is the quality of connective tissue in the studied organs, which is better in NBF fixed tissues compared to FF, while FF stands out as better when staining digestive system organs with HE. Therefore, if using NBF, certain sensitive tissues, such as the digestive organs, may require modification of standard staining procedures, and in particular the HE method, to provide better tissue affinity for color and thus better recognition of tissue morphological structures, while search for adequate non-formaline fixative still continues.

Važnost provjere sterilnosti hranjivih podloga za identifikaciju mikroorganizama prije upotrebe u mikrobiološkom laboratoriju [Elektronička građa] / Adis Hrvačić. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Sažetak ; Abstract. - Mikrobiološka kontaminacija hranjivih podloga koje se upotrebljavaju za uzgajanje mikroorganizama prilično je česta u mikrobiološkim laboratorijima. Tijekom pripreme hranjivih podloga za uzgoj i izolaciju čistih bakterijskih kultura vjerojatnost kontaminacije velika je ili zbog neadekvatne sterilizacije, nepravilnog rukovanja ili neadekvatne kontrole uvjeta pohrane i provjere roka trajanja. Pripremljene ploče ne smiju se odmah upotrebljavati ili čuvati na niskoj temperaturi dok se ne testiraju na sterilnost. Provjera sterilnosti vrlo je važan segment prije upotrebe ploča za mikrobiološke postupke i procedure i jedan od glavnih faktora koji utječe na validnost rezultata ispitivanja u mikrobiološkom laboratoriju. Cilj je rada uspostaviti kriterije odbacivanja kontaminiranih ploča. Pripremljena su tri seta ploča hranjivih podloga koji su tijekom 18 do 24 sata inkubirani na sobnoj temperaturi za provjeru sterilnosti. Procjena kontaminacije: porast kolonije na površini ili ispod nje. Inkubacija ploča produžena je za još jedan dan za razvoj kontaminacije na pločama na kojima nije bilo porasta kolonija prvog dana. Rezultati su otkrili da su u dvije skupine pronađene dvije vrste kontaminacije. Prvi set ploča ima kolonije na površini i kontaminacija nije pronađena drugog dana na nekontaminiranim pločama, što ukazuje na to da bi se kontaminacija mogla dogoditi tijekom postupaka nepravilnog rukovanja pločama. Druga skupina ima kolonije ispod površine i zagađenje se drugog dana razvijalo i u nekontaminiranim pločama zbog nepravilne sterilizacije staklenog posuđa ili nepravilne sterilizacije hranjivih medija. - Microbial contamination of the nutrient media used for the cultivation of microorganisms is quite common in microbiology laboratories. During the preparation of nutrient media for the cultivation and isolation of pure bacterial cultures, the likelihood of contamination is high either due to inadequate sterilization, improper handling or inadequate control of storage conditions and to check shelf life. Prepared plates should not be used immediately or stored at low temperature until they are tested for sterility. Sterility testing is a very important segment prior to the use of microbial plates and procedures and one of the major factors affecting the validity of test results in a microbiology laboratory. The aim of the paper is to establish criteria for rejection of contaminated plates. Three sets of plates of nutrient medium were prepared and incubated at room temperature for 18-24 h to check for sterility. Contamination assessment: colony growth on or below the surface. Plate incubation was extended by another day for the development of contamination on plates on which no colonies had grown on day one. The results revealed that two types of contamination were found in the two groups. The first set of plates had colonies on the surface and contamination was not found the next day on uncontaminated plates indicating that contamination could occur during improper handling of the plates. The second group has colonies below the surface and pollution developed on the second day in non-contaminated plates due to improper sterilization of glassware or improper sterilization of nutrient media. Understanding the importance of sterility testing before using nutrient media for the cultivation of microorganisms of interest, it is recommended that sterility confirmed plates be used for further microbiological procedures, while all other sets of contaminated plates establish rejection criteria regardless of how they are produced and what type of contamination is found.

Analytical bias of automated immunoassays for six serum steroid hormones assessed by LC-MS/MS [Elektronička građa] / Željko Debeljak, Ivana Marković, Jasna Pavela, Iva Lukić, Dario Mandić, Sanja Mandić, Vesna Horvat, Vatroslav Šerić. - Graf. prikazi.
Bibliografija: 23 jed. - Summary. - Introduction: There is a growing amount of evidence showing the significant analytical bias of steroid hormone immunoassays, but large numberof available immunoassays makes conduction of a single comprehensive study of this issue hardly feasible. Aim of this study was to assessthe analytical bias of six heterogeneous immunoassays for serum aldosterone, cortisol, dehydroepiandrosterone sulphate (DHEAS), testosterone,17-hydroxyprogesterone (OHP) and progesterone using the liquid chromatography coupled to the tandem mass spectrometry (LC-MS/MS).Materials and methods: This method comparison study included 49 serum samples. Testosterone, DHEAS, progesterone and cortisol immunoassayswere performed on the Abbott Architect i2000SR or Alinity i analysers (Abbott Diagnostics, Chicago, USA). DiaSorin’s Liaison (DiaSorin, Saluggia,Italy) and DIAsource’s ETI-Max 3000 analysers (DIAsource ImmunoAssays, Louvain-La-Neuve, Belgium) were chosen for aldosterone and OHPimmunoassay testing, respectively. All immunoassays were evaluated against the LC-MS/MS assay relying on the commercial kit (Chromsystems,Gräfelfing, Germany) and LCMS-8050 analyser (Shimadzu, Kyoto, Japan). Analytical biases were calculated and method comparison was conductedusing weighted Deming regression analysis.Results: Depending on the analyte and specific immunoassay, mean relative biases ranged from -31 to + 137%. Except for the cortisol, immunoassayswere positively biased. For none of the selected steroids slope and intercept 95% confidence intervals simultaneously contained 0 and 1,respectively.Conclusions: Evaluated immunoassays failed to satisfy requirements for methods’ comparability and produced significant analytical biases in respectto the LC-MS/MS assay, especially at low concentrations.

Analytical verification and comparison of chromogenic assays for dabigatran, rivaroxaban and apixaban determination on BCSXP and STA Compact Max analysers [Elektronička građa] / Ivana Ćelap, Sandra Margetić, Marija Brčić, Roman Mihić. - Graf. prikazi.
Bibliografija: 13 jed. - Summary. - Introduction: The aim of the study was to perform analytical verification and comparison of chromogenic assays for determination of dabigatran,rivaroxaban and apixaban concentration on BCSXP and STA Compact Max analysers.Materials and methods: Precision, linearity, measurement uncertainty estimation and determination of limit of blank, limit of determination and limit of quantification were calculated. Analytical performance specifications were set according to manufacturer specifications and literature data on between laboratory variability. Comparison of the methods was done using Bland-Altman and Passing-Bablok regression analysis.Results: Obtained results have shown acceptable precision on STA Compact Max only for dabigatran (CV = 3.5%) at lower concentration level comparing to manufacturer declaration (CV = 3.6%). On BCSXP, the highest coefficient of variation has been shown for apixaban (6.1%) at lower concentration level. Within laboratory precision was not met on STA Compact Max for all assays. Bland-Altman analysis has shown statistically significant bias for dabigatran (23.2%, 95%CI 11.2 – 35.3; P <0.001) and apixaban (8.4%, 95%CI 1.2 – 15.6; P = 0.023). Passing-Bablok regression analysis has shown systematic and proportional deviation between methods for rivaroxaban (y = 6.52 (2.94 to 11.83) + 0.84 (0.80 to 0.89) x.Conclusion: Chromogenic assays for dabigatran, rivaroxaban and apixaban on BCSXP and STA Compact Max analysers are shown as methods with satisfactory long-term analytical performance specifications for determination of direct oral anticoagulants in clinical laboratories. However, we cannot recommend interchangeable use because of the significant bias between assays.

Case report of a phantom pheochromocytoma [Elektronička građa] / Caroline M. Joyce, Audrey Melvin, Paula M. O'Shea, Seán J. Costelloe, Domhnall J. O'Halloran. - Graf. prikazi.
Bibliografija: 19 jed. - Summary. - Plasma free metanephrines or urinary fractionated metanephrines are the biochemical tests of choice for the diagnosis of pheochromocytoma as they have greater sensitivity and specificity than catecholamines for pheochromocytoma detection. This case highlights the preanalytical factors which can influence metanephrine measurement and cause a false positive result. It describes a patient with a high pre-test probability of pheochromocytoma due to hypertension and a past medical history of adrenalectomy for a purported pheochromocytoma in her home country. When biochemical screening revealed grossly elevated urine normetanephrine in the presence of a previously identified right adrenal lesion, there was high clinical suspicion of a pheochromocytoma. However, functional imaging did not support this view which prompted additional testing with plasma metanephrines. Results for plasma and urine metanephrines were discordant and preanalytical drug interference was suspected. Patient medications were reviewed and sulfasalazine, an anti-inflammatory drug was identified as the most likely analytical interferent. Urinary fractionated metanephrines were re-analysed using liquid chromatography tandem mass spectrometry (LC-MS/MS) and all metanephrines were within their reference intervals. This case illustrates how method-specific analytical drug interference prompted unnecessary expensive imaging, heightened patient anxiety and resulted in lengthy investigations for what turned out to be a phantom pheochromocytoma.

Case report of spuriously low sodium and calcium in a 36-year-old male in primary care [Elektronička građa] / Seán J. Costelloe, Kelly McCarthy, Marguerite O'Connell, Mark Butler. - Graf. prikazi.
Bibliografija: 11 jed. - Summary. - An unseparated serum specimen for a 36-year-old male was received from primary care. The specimen arrived in the laboratory at Cork University Hospital one day after collection, as documented on the paper request card, and was promptly centrifuged. Analysis was delayed for three days due to operational constraints and serum indices were run at the same time as the biochemical analyses. Results showed a moderately haemolysed specimen with remarkably low concentrations of both sodium (119 mmol/L) and total calcium (1.15 mmol/L), with all other parameters within their appropriate reference intervals (RIs). The complete report was released electronically and both sodium and calcium results were phoned to, and acknowledged by, the requesting general practitioner (GP). Discussion between the medical scientists and clinical biochemist on duty raised the possibility that the specimen was significantly older than initially thought. Further discussion of results with the GP clarified that the documented time of collection corresponded with specimen receipt by the courier, rather than the time of phlebotomy. Thus, the specimen was 7 days old when received in the laboratory and 10 days old when analysed. This case illustrates the dangers of multiple convergent preanalytical errors. Laboratories should be mindful of the stability of analytes in unseparated blood and unusual patterns of results which might suggest a specimen is “old”, and that this may coexist with erroneous request information. Any potential adverse effects on patient care were prevented in this case by laboratory vigilance.

Comparison of a rapid immunochromatographic test with a chemiluminescenceimmunoassay for detection of anti-SARS-CoV-2 IgM and IgG [Elektronička građa] / Caterina Maria Gambino, Bruna Lo Sasso, Claudia Colomba, Rosaria Vincenza Giglio, Luisa Agnello, Giulia Bivona, Marcello Ciaccio. - Graf. prikazi.
Bibliografija: 10 jed. - Summary. - Introduction: The 2019 Coronavirus disease (COVID-19) has been characterized as a pandemic, representing a serious global public health emergency.Serological tests have been proposed as reliable tools for detecting Coronavirus SARS-CoV-2 antibodies in infected patients, especially forsurveillance or epidemiological purposes. The aim of this study is to evaluate the agreement between the IgM/IgG rapid assays, based on lateral flowimmunochromatographic assay, and the fully automated 2019-nCoV IgM and IgG, based on chemiluminescence immunoassay.Materials and methods: SARS-CoV-2 antibodies were measured with the BIOSYNEX COVID-19 BSS IgM/IgG test (BIOSYNEX, Illkirch-Graffenstaden,France) and the MAGLUMI CLIA (IgM and IgG) (SNIBE – Shenzhen New Industries Biomedical Engineering, Shenzhen, China) in 70 serum samplesfrom patients with PCR-confirmed diagnosis. The strength of the agreement of the two methods was calculated by using the Cohen Kappa index.Results: The results showed a good grade of concordance between the two immunoassays with a Cohen’s kappa coefficient of 0.71 (95%CI: 0.54-0.87) for IgG SARS-CoV-2 antibodies and 0.70 (95%CI: 0.53-0.87) for IgM SARS-CoV-2 antibodies. In addition, the rapid assays BIOSYNEX COVID-19BSS for detecting SARS-CoV-2 antibodies showed a positive likelihood ratio (LR) of 10.63 (95%CI: 2.79-40.57) for IgG and a LR of 6.79 (95%CI: 2.93-15.69) for IgM.Conclusion: Our results suggest that the immunochromatographic rapid IgM/IgG test and the chemiluminescence IgM and IgG immunoassay havea good degree of concordance, suggesting that both could be considered as useful tools for epidemiologic surveillance.

Dark brown serum and plasma samples [Elektronička građa] : a case report / Lora Dukic, Nikolina Maric, Ana-Maria Simundic. - Graf. prikazi.
Bibliografija: 11 jed. - Summary. - This case report describes occurrence of unusual, dark brown coloration of citrate plasma and serum samples in a female 68 years old patient admittedinto Emergency department (ED).Patient complained of nausea and vomiting, fever up to 38.9°C, colicky pain in abdomen, diminished urinary output and yellowish skin tone. Hermedical history included arterial hypertension, hypothyroidism and facial squamous cell carcinoma. For previous two years, she was treated withtuberculostatic therapy for Mycobacterium avium positive interstitial lung disease. Regular follow-up showed no signs of active disease. Upon admissionto ED, complete blood count (CBC) analysis showed low red blood count (RBC) (3.76 x1012/L (reference interval (RI) 3.86 – 5.08 x1012/L)), lowhaemoglobin (Hb) concentration (111 g/L (RI 119 - 157 g/L)) and low haematocrit (Hct) (0.310 L/L (RI 0.360 – 0.470 L/L)). Biochemistry analytes werehigh, with foremost lactate dehydrogenase (LD) activity (2900 U/L, RI <240 U/L). After communication with the clinician, methaemoglobin measuredin arterial blood gas sample was reported. Patient was admitted to the Intensive care unit and upon reflex testing of haptoglobin, intravascularhaemolysis was confirmed. This case indicates that every case of brown coloration of the serum must be promptly communicated to the clinician.Reflex testing assured timely diagnosis and favourable patient outcome.

Investigating the prospect of copper-histidine complex modified gold electrode for histidine and human serum albumin recognition [Elektronička građa] / Irena Kereković, Sandra Domjanić Drozdek. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Summary ; Sažetak. - Histidine monolayer was adsorbed on the surface of the gold electrode and further tailored with Cu2+ cation with the aim to investigate adsorption of histidine (His) and human serum albumin (HSA). Formation of the layer on the surface of the gold electrode was confirmed with quartz crystal microbalance. Binding of the His and HSA onto the modified electrode was successfully done for a wide range of tested concentrations. Electrode response was linearly proportional to the concentration of His and HSA with the correlation coefficients R2 = 0.9895 and R2 = 0.9952 respectively. - Histidinski monosloj adsorbiran je na zlatnu elektrodu i dalje modificiran kationom Cu2+. Cilj je bio istražiti vezanje histidina (His) i humanog albumina (HSA) na tako pripremljenu površinu. Formiranje sloja na površini zlatne elektrode potvrđeno je kvarcnom mikrovagom. Vezanje histidina i humanog albumina na modificiranu elektrodu uspješno je izvršeno za širok raspon ispitivanih koncentracija. Dobiven je odziv linearno proporcionalan koncentraciji histidina i humanog albumina s koeficijentom korelacije R2 = 0,9895 odnosno R2 = 0,9952.

The results of external quality assessment programme on urine leukocyte and erythrocyte counting in Poland [Elektronička građa] / Agnieszka Ćwiklińska, Robert Kowalski, Barbara Kortas-Stempak, Agnieszka Kuchta, Aleksandra Fijałkowska, Gabriela Bednarczuk, Maciej Jankowski. - Graf. prikazi.
Bibliografija: 23 jed. - Summary. - Introduction: Urine particle analysis is an important diagnostic tool. The aim of this study was to evaluate the quality of urine leukocyte (WBC) and erythrocyte (RBC) counting results obtained with manual and automated methods in Polish laboratories participating in the international external quality assessment (EQA) programme. Materials and methods: 1400 WBC and RBC counting results were obtained from 183 laboratories in EQA surveys organised by Labquality (Helsinki, Finland) from 2017 to 2019. The between-laboratory coefficient of variation (CV), the percentage difference between the laboratories' results and target values (Q-score (%)), as well as modified Youden plots were analysed. Results: For automated method groups, the medians of inter-laboratory CVs varied from 14% to 33% for WBC counting and from 10% to 39% for RBC counting. For manual method groups, the medians of CV varied from 53% to 71% (WBC) and from 55% to 70% (RBC), and they were significantly higher, in comparison to CVs for most automated method groups (P <0.001). The highest percentage of results outside the target limits (36%) and the highest range of Q-score (%) (from - 93% to 706%) were observed for laboratories which participated in the surveys for the first or second time. The percentage of deviating results and the ranges of Q-score decreased with an increased frequency of laboratories’ participation in the surveys. Conclusions: The quality of manual methods of urine WBC and RBC counting is unsatisfactory. There is an urgent need to take actions to improve laboratories’ performance and to increase harmonisation of the results.

SARS-CoV-2 - a new challenge for laboratory medicine [Elektronička građa] / Slavica Dodig, Ivana Čepelak, Daniela Čepelak Dodig, Renata Laškaj. - Graf. prikazi.
Bibliografija: 48 jed. - Summary. - The new corona virus SARS-CoV-2 (Severe Acute Respiratory Syndrome Corona Virus 2) causes a disease called COVID-19 (coronavirus disease 2019), that develops mostly in subjects with already impaired immune system function, primarily in the elderly and in individuals with some chronic disease or condition. The reasons for this should be sought in the processes of aging and chronic latent inflammation, i.e. immunosenescence and inflammaging. Laboratory medicine specialists are currently focused on proving the presence of the virus and defining biomarkers that would enable the prediction of disease progression. For now, it has been shown that useful biomarkers can include general biomarkers of inflammation (parameters of complete blood count, C-reactive protein, interleukin-6, procalcitonin), biomarkers of myocardial damage (high sensitivity troponin I/T, B-type natriuretic peptide, and N-terminal B type natriuretic peptide), and vascular biomarkers (D-dimer, prothrombin time, fibrinogen). Their actual diagnostic specificity, sensitivity and predictive value need to be tested on a larger number of subjects. In addition, it is important to find and evaluate specific biomarkers of immunosenescence.

Six Sigma revisited [Elektronička građa] : we need evidence to include a 1.5 SD shift in the extraanalytical phase of the total testing process / Abdurrahman Coskun, Cristiano Ialongo. - Graf. prikazi.
Bibliografija: 9 jed. - Summary. - The Six Sigma methodology has been widely implemented in industry, healthcare, and laboratory medicine since the mid-1980s. The performanceof a process is evaluated by the sigma metric (SM), and 6 sigma represents world class performance, which implies that only 3.4 or less defects (orerrors) per million opportunities (DPMO) are expected to occur. However, statistically, 6 sigma corresponds to 0.002 DPMO rather than 3.4 DPMO.The reason for this difference is the introduction of a 1.5 standard deviation (SD) shift to account for the random variation of the process around itstarget. In contrast, a 1.5 SD shift should be taken into account for normally distributed data, such as the analytical phase of the total testing process;in practice, this shift has been included in all type of calculations related to SM including non-normally distributed data. This causes great deviationof the SM from the actual level. To ensure that the SM value accurately reflects process performance, we concluded that a 1.5 SD shift should be usedwhere it is necessary and formally appropriate. Additionally, 1.5 SD shift should not be considered as a constant parameter automatically included inall calculations related to SM.

Statistical distributions commonly used in measurement uncertainty in laboratory medicine [Elektronička građa] / Abdurrahman Coskun, Wytze P. Oosterhuis. - Graf. prikazi.
Bibliografija: 19 jed. - Summary. - Uncertainty is an inseparable part of all types of measurement. Recently, the International Organization for Standardization (ISO) released a new standard (ISO 20914) on how to calculate measurement uncertainty (MU) in laboratory medicine. This standard can be regarded as the beginning of a new era in laboratory medicine. Measurement uncertainty comprises various components and is used to calculate the total uncertainty. All components must be expressed in standard deviation (SD) and then combined. However, the characteristics of these components are not the same; some are expressed as SD, while others are expressed as a ± b, such as the purity of the reagents. All non-SD variables must be transformed into SD, which requires a detailed knowledge of common statistical distributions used in the calculation of MU. Here, the main statistical distributions used in MU calculation are briefly summarized.

Study of the preanalytical variables affecting the measurement of clinically relevant free-circulating microRNAs [Elektronička građa] : focus on sample matrix, platelet depletion, and storage conditions / Martina Faraldi, Veronica Sansoni, Silvia Perego, Marta Gomarasca, Jakub Kortas, Ewa Ziemann, Giuseppe Banfi, Giovanni Lombardi. - Graf. prikazi.
Bibliografija: 29 jed. - Summary. - Introduction: Circulating microRNAs (miRNAs) are emerging as potential biomarkers. However, the lack of preanalytical and analytical standardization limits their use. The aim of this study was to determine the expression of different miRNAs in plasma according to different collection and storage conditions.Materials and methods: Venous blood from 10 volunteers was collected in tubes spray-coated with dipotassium salt of ethylendiaminetetraaceticacid, either with (plasma-preparation tube, PPT) or without (K2EDTA) gel separator. Platelet-poor plasma (PPP) was also obtained from K2EDTA plasma. After storage under different conditions, miRNA-enriched total RNA was isolated from plasma and reverse transcribed. A panel of 179 miRNAs was assayed by quantitative polymerase chain reaction and the results were analysed by GenEx software. Detectability and stability of miRNAs were determined.Results: The number of undetected miRNAs was: 18, 24, and 22 in PPT; 83, 43, and 20 in K2EDTA; and 76, 106, and 104 in PPP samples, for plasma immediately frozen at - 80°C and plasma stored for 24h at room temperature or 4°C, respectively. Circulating miRNA expression in PPT samples was not affected by storage delay or temperature, while the percentage of up- and down-regulated miRNA in K2EDTA and PPP samples ranged from 2%, and 1% to 7%, and 5%, respectively.Conclusions: Sample matrix, temperature and delay in storage strongly influence the expression level of plasma miRNAs. Our results indicate PPT tubes as the most suitable matrix to improve total miRNA detectability and stability, independently of temperature.

Unexpected abnormal coagulation test results in a 2-year-old child [Elektronička građa] : a case report / Patricija Banković Radovanović, Tanja Živković Mikulčić, Jasmina Simović Medica. - Graf. prikazi.
Bibliografija: 22 jed. - Summary. - Rejection of the sample with repeated blood withdrawal is always an unwanted consequence of sample nonconformity and preanalytical errors,especially in the most vulnerable population – children. Here is presented a case with unexpected abnormal coagulation test results in a 2-yearoldchild with no previously documented coagulation disorder. Child is planned for tympanostomy tubes removal under the anaesthesia drivenprocedure, and preoperative coagulation tests revealed prolonged prothrombin time, activated partial thromboplastin time and thrombin time,with fibrinogen and antithrombin within reference intervals. From the anamnestic and clinical data, congenital coagulation disorder was excluded,and with further investigation, sample mismatch, clot presence and accidental ingestion of oral anticoagulant, heparin contamination or vitamin Kdeficiency were excluded too. Due to suspected EDTA carryover during blood sampling another sample was taken the same day and all tests wereperformed again. The results for all tests were within reference intervals confirming EDTA effect on falsely prolongation of the coagulation times inthe first sample. This case can serve as alert to avoid unnecessary loss in terms of blood withdrawal repetitions and discomfort of the patients andtheir relatives, tests repeating, prolonging medical procedures, and probably delaying diagnosis or proper medical treatment. It is the responsibilityof the laboratory specialists to continuously educate laboratory staff and other phlebotomists on the correct blood collection as well as on its importancefor the patient’s safety.

Sacred groves in conservation of biodiversity in Odisha [Elektronička građa] / Taranisen Panda, Nirlipta Mishra, Bikram K. Pradhan, Shaik Rahimuddin, Rajballav Mohanty. - Ilustr., graf. prikazi.
Bibliografija: 33 jed. - Summary. - Phytodiversity survey of sacred groves was carried out for a period of two years (2016-2018) in Bhadrak district of Odisha, India. A total of 42 plant species belonging to 39 genera under 26 families are recorded from 20 selected sacred groves of the district. Moraceae represents the dominant family. The respondents affirmed that the plants inside these sites are never cut or harmed and some plant like neem (Azadirachta indica A. Juss.), banyan (Ficus benghalensis L.) and peepal (Ficus religiosa L.) present in the sacred groves are more than a century old. The present study indicates the role of sacred groves in biodiversity conservation through faith, belief, religious activity and community participation.

Polyhydroxyalkanoates - linking properties, applications and end-of-life options [Elektronička građa] / Martin Koller, Anindya Mukherjee. - Graf. prikazi.
Bibliografija: 90 jed. - Summary. - When it comes to "bioplastics", we currently notice an immense complexity of this topic, and, most of all, a plethora of contradictory legislations, which confuses or even misleads insufficiently informed consumers. The present article therefore showcases microbial polyhydroxyalkanoate (PHA) biopolyesters as the prime class of “bioplastics” sensu stricto. In particular, biodegradability of PHA as its central benefit in elevating the current plastic waste scenario is elaborated on the biochemical basis: this covers aspects of the enzymatic machinery involved both in intra- and extracellular PHA degradation, and environmental factors impacting biodegradability. Importantly, PHA degradability is contextualized with potential fields of application of these materials. It is further shown how the particularities of PHA in terms of feedstocks, mode of synthesis, degradability, and compostability differ from other polymeric materials sold as "bioplastics", highlighting the unique selling points of PHA as “green” plastic products in the circular economy. Moreover, current standards, norms, and certificates applicable to PHA are presented as basis for a straight-forward, scientifically grounded classification of "bioplastics".

Analysis of serum homocysteine in the laboratory practice - comparison of the direct chemiluminescence immunoassay and high performance liquid chromatography coupled with fluorescent detection [Elektronička građa] / Łukasz Paprotny, Dorota Wianowska, Magdalena Izdebska, Agnieszka Celejewska, Dorota Szewczak, Janusz Solski. - Graf. prikazi.
Bibliografija: 27 jed. - Summary. - Introduction: Effective diagnosis of cardiovascular diseases requires the right tools to be used enabling selective and sensitive analysis of their biomarkers.One of them is homocysteine (Hcy), nowadays determined by immunoassays and chromatographic methods. This study aims to comparethe results obtained by direct chemiluminescence immunoassay (CLIA) and high performance liquid chromatography with fluorescent detection(HPLC-FD) using commercial kits.Materials and methods: Homocysteine concentration was determined in serum samples obtained from 101 individuals, using Atellica IM HCY(Siemens Healthineers, Erlangen, Germany) and HCY in plasma/serum – HPLC-FD (Chromsystems Instruments & Chemicals GmbH, Gräfelfing, Germany)tests validated for routine analysis. The latter was applied as a reference method. The comparability and agreement between the tested methodswere evaluated using the Passing-Bablok (PB) regression analysis and the Bland-Altman (BA) method of the differences analysis.Results: Studies showed that CLIA gives higher Hcy concentrations (15.7 ± 4.14 μmol/L). Passing-Bablok regression analysis of the results obtainedwith CLIA (y) compared with HPLC-FD (x) yielded an intercept of 0.22 (95%CI: - 2.16 to 2.46) and slope of 1.58 (95%CI: 1.33 to 1.87). Bland-Altmananalysis demonstrated a systematic positive bias for CLIA of 5.85 ± 2.77 μmol/L.Conclusions: Methods disagreement precludes their interchangeability. Lower Hcy values by HPLC-FD result from its greater selectivity. High performanceliquid chromatography with fluorescent detection should be considered as preferential method for analysing Hcy in blood serum as well asthe recommended reference method for routine clinical analysis. This fact, however, imposes the need to establish new reference ranges.

Analytical performance assessment and improvement by means of the Failure mode and effect analysis (FMEA) [Elektronička građa] / Leonor Guiñón, Anna Soler, Mónica Gisell Díaz, Rosa María Fernández, Nayra Rico, Josep Lluís Bedini, Aurea Mira, Luisa Alvarez. - Graf. prikazi.
Bibliografija: 27 jed. - Summary. - Introduction: Laboratories minimize risks through quality control but analytical errors still occur. Risk management can improve the quality of processes and increase patient safety. This study aims to use the failure mode and effect analysis (FMEA) to assess the analytical performance and measure the effectiveness of the risk mitigation actions implemented. Materials and methods: The measurands to be included in the study were selected based on the measurement errors obtained by participating in an External Quality Assessment (EQA) Scheme. These EQA results were used to perform an FMEA of the year 2017, providing a risk priority number that was converted into a Sigma value (σFMEA). A root-cause analysis was done when σFMEA was lower than 3. Once the causes were determined, corrective measures were implemented. An FMEA of 2018 was carried out to verify the effectiveness of the actions taken. Results: The FMEA of 2017 showed that alkaline phosphatase (ALP) and sodium (Na) presented a σFMEA of less than 3. The FMEA of 2018 revealed that none of the measurands presented a σFMEA below 3 and that σFMEA for ALP and Na had increased. Conclusions: Failure mode and effect analysis is a useful tool to assess the analytical performance, solve problems and evaluate the effectiveness of the actions taken. Moreover, the proposed methodology allows to standardize the scoring of the scales, as well as the evaluation and prioritization of risks.

GAY, Stephanie
Changes in error rates in the Australian key incident monitoring and management system program [Elektronička građa] / Stephanie Gay, Tony Badrick. - Graf. prikazi.
Bibliografija: 18 jed. - Summary. - Introduction: The Key incident monitoring and management system program (KIMMS) program collects data for 19 quality indicators (QIs) from Australian medical laboratories. This paper aims to review the data submitted to see whether the number of errors with a higher risk priority number (RPN) have been reduced in preference to those with a lower RPN, and to calculate the cost of these errors. Materials and methods: Data for QIs from 60 laboratories collected through the KIMMS program from 2015 until 2018 were retrospectively reviewed. The results for each QI were averaged for the four-year average and coefficient of variation. To review the changes in QI frequency, the yearly averages for 2015 and 2018 were compared. By dividing the total RPN by 4 and multiplying that number by the cost of recollection of 30 AUD, it was possible to assign the risk cost of these errors. Results: The analysis showed a drop in the overall frequency of incidents (6.5%), but a larger drop in risk (9.4%) over the period investigated. Recollections per year in Australia cost the healthcare industry 27 million AUD. If the RPN data is used, this cost increases to 66 million AUD per year. Conclusions: Errors with a higher RPN have fallen more than those with lower RPN. The data shows that the errors associated with phlebotomy are the ones that have most improved. Further improvements require a better understanding of the root cause of the errors and to achieve this, work is required in the collection of the data to establish best-practice guidelines.

Chromogenic anti-FXa assay calibrated with low molecular weight heparin in patients treated with rivaroxaban and apixaban [Elektronička građa] : possibilities and limitations / Sandra Margetić, Ivana Ćelap, Diana Delić Brkljačić, Nikola Pavlović, Sandra Šupraha Goreta, Ivana Kobasić, Arijana Lovrenčić-Huzjan, Vanja Bašić Kes. - Graf. prikazi.
Bibliografija: 26 jed. - Summary. - Clinical application of rivaroxaban and apixaban does not require therapeutic monitoring. Commercial anti-activated factor X (anti-FXa) inhibition methods for all anti-FXa drugs are based on the same principle, so there are attempts to evaluate potential clinical application of heparin-calibrated anti-FXa assay as an alternative method for direct FXa inhibitors. We aimed to evaluate relationship between anti-FXa methods calibrated with low molecular weight heparin (LMWH) and with drug specific calibrators, and to determine whether commercial LMWH anti-FXa assay can be used to exclude the presence of clinically relevant concentrations of rivaroxaban and apixaban. Materials and methods: Low molecular weight heparin calibrated reagent (Siemens Healthineers, Marburg, Germany) was used for anti-FXa activity measurement. Innovance heparin (Siemens Healthineers, Marburg, Germany) calibrated with rivaroxaban and apixaban calibrators (Hyphen BioMed, Neuville-sur-Oise, France) was used for quantitative determination of FXa inhibitors. Results: Analysis showed good agreement between LMWH calibrated and rivaroxaban calibrated activity (κ = 0.76) and very good agreement with apixaban calibrated anti-Xa activity (κ = 0.82), respectively. Low molecular weight heparin anti-FXa activity cut-off values of 0.05 IU/mL and 0.1 IU/mL are suitable for excluding the presence of clinically relevant concentrations (<30 ng/mL) of rivaroxaban and apixaban, respectively. Concentrations above 300 ng/mL exceeded upper measurement range for LMWH anti-FXa assay and cannot be determined by this method. Conclusion: Low molecular weight heparin anti-FXa assay can be used in emergency clinical conditions for ruling out the presence of clinically relevant concentrations of rivaroxaban and apixaban. However, use of LMWH anti-FXa assay is not appropriate for their quantitative determination as an interchangeable method.

The effect of jet-lag on serum concentrations of thyroid stimulating hormone and prolactin [Elektronička građa] : a case report / Merve Sibel Gungoren, Deniz Ilhan Topcu, Cevdet Zungun. - Graf. prikazi.
Bibliografija: 7 jed. - Summary. - Introduction: This case report is about the importance of sleeping status for analysis of thyroid hormone stimulating hormone (TSH) and prolactin (PRL) which arose from discordant results of a patient who was referred for serum TSH and PRL testing within 12-hour period after an intercontinental flight. Case description: An adult male patient was admitted to our laboratory for serum TSH and PRL tests and came back questioning the accuracy of his previous results. Further investigations: A new analysis with a new sample was offered. His new results were not consistent with his previous results. What happened: It was revealed that the night before the first sampling, he travelled back to Turkey from The United States of America and came to testing within 12 hours after the arrival. Discussion: Sleeping status is one of the factors that can affect laboratory results. Intercontinental flights causing jet-lag can alter the secretions of TSH and PRL which are predominantly modulated by thyrotropin-releasing hormone (TRH). Main lesson: Travel history and sleeping status are important factors to be evaluated prior sampling for hormone analysis. Patients must be informed about the importance of sampling timing.

Errors within the total laboratory testing process, from test selection to medical decision-making [Elektronička građa] : a review of causes, consequences, surveillance and solutions / Cornelia Mrazek, Giuseppe Lippi, Martin H Keppel, Thomas K Felder, Hannes Oberkofler, Elisabeth Haschke-Becher, Janne Cadamuro. - Graf. prikazi.
Bibliografija: 108 jed. - Summary. - Laboratory analyses are crucial for diagnosis, follow-up and treatment decisions. Since mistakes in every step of the total testing process may potentially affect patient safety, a broad knowledge and systematic assessment of laboratory errors is essential for future improvement.In this review, we aim to discuss the types and frequencies of potential errors in the total testing process, quality management options, as well as tentative solutions for improvement. Unlike most currently available reviews on this topic, we also include errors in test-selection, reporting and interpretation/action of test results. We believe that laboratory specialists will need to refocus on many process steps belonging to the extra-analytical phases, intensifying collaborations with clinicians and supporting test selection and interpretation. This would hopefully lead to substantial improvements in these activities, but may also bring more value to the role of laboratory specialists within the health care setting.

Experience on how to implement a preanalytical and POCT unit in Madrid's IFEMA field hospital during this unprecedented COVID-19 emergency [Elektronička građa] / Jorge Díaz–Garzón, Paloma Oliver, Gema Crespo, Marta Duque, Pilar Fernandez-Calle, Marta Gómez, Roberto Mora, Isabel Moreno, Lydia Pascual, Ana-Laila Qasem, Olaia Rodriguez-Fraga, Manuela Simón, Antonio Buño.
Summary. - To fight the virus SARS-CoV-2 spread to Europe from China and to give support to the collapsed public health system, the Spanish Health Authorities developed a field hospital located in the facilities of Madrid exhibition centre (IFEMA) to admit and treat patients diagnosed with SARS-CoV-2 infectious disease (COVID-19). The Department of Laboratory Medicine of La Paz University Hospital in Madrid (LMD-HULP) was designated to provide laboratory services. Due to the emergency, the IFEMA field hospital had to be prepared for patient admission in less than 1 week and the laboratory professionals had to collaborate in a multidisciplinary group to assure that resources were available to start on time. The LMD-HULP participated together with the managers in the design of the tests portfolio and the integration of the healthcare information systems (IS) (hospital IS, laboratory IS and POCT management system). Laboratorians developed a strategy to quickly train clinicians and nurses on test requests, sample collection procedures and management/handling of the POCT blood gas analyser both by written materials and training videos. The IFEMA´s preanalytical unit managed 3782 requests, and more than 11,000 samples from March 27th to April 30th. Furthermore, 1151 samples were measured by blood gas analysers. In conclusion, laboratory professionals must be resilient and have to respond timely in emergencies as this pandemic. The lab’s personnel selection, design and monitoring indicators to maintain and further improve the quality and value of laboratory services is crucial to support medical decision making and provide better patient care.

General position of Croatian medical biochemistry laboratories on autovalidation [Elektronička građa] : survey of the Working group for post-analytics of the Croatian Society of Medical Biochemistry and Laboratory Medicine / Vladimira Rimac, Anja Jokic, Sonja Podolar, Jelena Vlasic Tanaskovic, Lorena Honovic, Jasna Lenicek Krleza. - Graf. prikazi.
Bibliografija: 21 jed. - Summary. - Introduction: Autovalidation (AV) is an algorithm based on predefined rules designed, among others, to automate and standardize the postanalytical phase of laboratory work. The aim of this study was to examine the overall opinion of Croatian medical biochemistry laboratories regarding various aspects of AV. Material and methods: This retrospective study is an analysis of the responses of a survey about AV comprised of 18 questions, as part of Module 10 (“Postanalytical phase of laboratory testing”) of national External Quality Assessment program, administered by the Croatian Centre for Quality Assessment in Laboratory Medicine. Results were reported as percentages of total number of participants in survey or as proportions of observed data if the overall number of data was <100. Results: 121 laboratories responded to the survey, of which 76% do not use AV, while 11% of laboratories use AV in routine laboratory work. 16/29 laboratories implemented semi-automated AV for general biochemistry (7/29), haematology (5/29), and coagulation (4/29) tests. Analytical measurement ranges, critical values, flags from analysers, interference indices and delta check were the most commonly used rules in the algorithm. 12/29 laboratories performed validation of AV with less than 500 samples (8/29). 7/13 laboratories report the percentage of AV being 20-50%, while 10/13 answered that introduction of AV significantly reduced turnaround time (TAT) (for 20 - 25%), especially for biochemistry tests. Conclusions: Despite of its numerous benefits (i.e. shorter TAT, less manual validation, standardization of the postanalytical phase), only a small number of Croatian laboratories use AV.

Health-related concepts and cognitive linguistics [Elektronička građa] / Marija Raguž, Hrvoje Roguljić, Marijana Jukić.
Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - Human behavior is governed by concepts. Concepts are cognitive representations of reality. Cognitive linguistics suggests that there are cognitive models affecting the formation of concepts in human mind, such as cognitive metaphor and a prototype model. We used the example of an ancient procedure – trepanation in order to show the connection between the procedure and the concept of the skull as a container, which is a metaphor. Most important concepts in medical systems are health and disease. There is no agreement about their exact definition, although there have been many studies focusing on that. Based on the previous research, we suggest possible benefits from approaching the disease as a prototype category. In all studies so far there have always been consistencies in rating entities qualifying as a disease which is a feature of a prototype category – membership gradience. Entities perceived as diseases by respondents in studies so far have not been the same, but they share certain features. It is more likely for an entity to be considered a disease if it can lead to death, for example. In our opinion there are common core features determining disease as a cognitive category. Further cross-cultural studies could answer what features an entity needs to have in order to be considered a disease.Stressing such features could improve patients’cooperation when a new disease appears. - Ljudskim ponašanjem upravljaju koncepti. Koncept je kognitivno predstavljena stvarnost. Prema kognitivnoj lingvistici, postoje kognitivni modeli koji utječu na oblikovanje koncepata u ljudskome umu. Među njih se ubrajaju kognitivna metafora i model prototipa. Na primjeru drevnoga postupka – trepanacije, prikazali smo povezanost samoga postupka i koncepta ljudske lubanje kao spremnika, što je metafora. Najvažniji su koncepti u medicinskome sustavu – zdravlje i bolest. Ne postoji njihova općenito prihvaćena definicija, mada je to bio predmet mnogih istraživanja. Na temelju prethodnih istraživanja moguće je zaključiti da postoje određene prednosti u pristupanju bolesti kao prototipnoj kategoriji. U svim dosadašnjim studijama postojala je dosljednost u procjenjivanju toga može li se određeni entitet kvalificirati kao bolest, što je karakteristika prototipne kategorije – stupnjevana pripadnost. Entiteti percipirani kao bolesti nisu jednaki za sve ispitanike u dosadašnjim studijama, ali dijele određene karakteristike. Veća je vjerojatnost da će neki entitet biti smatran bolešću ako može dovesti do smrtnog ishoda, na primjer. Smatramo kako postoji zajednička baza obilježja koja određuje bolest kao kognitivnu kategoriju. Daljnja međukulturna istraživanja mogla bi odgovoriti na pitanje koja su to obilježja koje entitet mora posjedovati kako bi ga se smatralo bolešću. Naglašavanje takvih obilježja moglo bi poboljšati suradljivost pacijenata u slučajevima pojave novih bolesti.

High anion gap metabolic acidosis caused by D-lactate [Elektronička građa] : mind the time of blood collection / Matthias Weemaes, Martin Hiele, Pieter Vermeersch. - Graf. prikazi.
Bibliografija: 14 jed. - Summary. - Introduction: D-lactic acidosis is an uncommon cause of high anion gap acidosis.Materials and methods: A 35-year old woman was admitted to the emergency room with somnolence, drowsiness, dizziness, incoherent speechand drunk appearance. Her past medical history included a Roux-en-Y bypass. Point-of-care venous blood analysis revealed a high anion gap acidosis.Based on the clinical presentation, routine laboratory results and negative toxicology screening, D-lactate and 5-oxoprolinuria were consideredas the most likely causes of the high anion gap acidosis. Urine organic acid analysis revealed increased lactate, but no 5-oxoproline. Plasma D-lactatewas <1.0 mmol/L and could not confirm D-lactic acidosis.What happened: Further investigation revealed that the blood sample for D-lactate was drawn 12 hours after admission, which might explain thefalse-negative result. Data regarding the half-life of D-lactate are, however, scarce. During a second admission, one month later, D-lactic acidosiscould be confirmed with an anion gap of 40.7 mmol/L and a D-lactate of 21.0 mmol/L measured in a sample collected at the time of admission.Main lesson: The time of blood collection is of utmost importance to establish the diagnosis of D-lactic acidosis due to the fast clearance of D-lactatein the human body.

In sickness and in health [Elektronička građa] : pivotal role of vitamin D / Nora Nikolac Gabaj, Adriana Unic, Marijana Miler, Tomislav Pavicic, Jelena Culej, Ivan Bolanca, Davorka Herman Mahecic, Lara Milevoj Kopcinovic, Alen Vrtaric. - Graf. prikazi.
Bibliografija: 96 jed. - Summary. - Within the last several years, frequency of vitamin D testing has multiplied substantially all over the world, since it has been shown to have an important role in many diseases and conditions. Even though liquid chromatography - tandem mass spectrometry (LC-MS/MS) has been identified as “gold standard” method for vitamin D measurement, most laboratories still use immunochemistry methods. Besides analytical problems (hydrophobicity, low circulating concentrations, ability to bind to lipids, albumins and vitamin D binding protein, presence of multiple vitamin D metabolites and variable ratios of 25(OH)D2 and 25(OH)D3 in the blood), vitamin D shows great preanalytical variability, since its concentration is drastically influenced by seasonal changes, exposure to sun, type of clothes or sun block creams. Vitamin D is mostly measured in serum or plasma, but new studies are showing importance of measuring vitamin D in pleural effusions, breast milk, urine, synovial fluid and saliva. Besides the main role in calcium homeostasis and bone metabolism, many studies linked vitamin D deficiency with cancer, cardiovascular diseases, diabetes, fertility and many other conditions. However, even though initial observational studies indicated that supplementation with vitamin D might be beneficial in disease development and progression; first results of well-designed randomized controlled prospective studies did not find differences in frequency of cardiovascular events or invasive cancer between patients taking vitamin D supplementation compared to placebo. In the light of these recent findings, validity of excessive vitamin D testing remains an open question.

Integrated diagnostics [Elektronička građa] : the future of laboratory medicine? / Giuseppe Lippi, Mario Plebani. - Graf. prikazi.
Bibliografija: 78 jed. - Summary. - The current scenario of in vitro and in vivo diagnostics can be summarized using the "silo metaphor", where laboratory medicine, pathology and radiology are three conceptually separated diagnostic disciplines, which will increasingly share many comparable features. The substantial progresses in our understanding of biochemical-biological interplays that characterize many human diseases, coupled with extraordinary technical advances, are now generating important multidisciplinary convergences, leading the way to a new frontier, called integrated diagnostics. This new discipline, which is currently defined as convergence of imaging, pathology and laboratory tests with advanced information technology, has an enormous potential for revolutionizing diagnosis and therapeutic management of human diseases, including those causing the largest number of worldwide deaths (i.e. cardiovascular disease, cancer and infectious diseases). However, some important drawbacks should be overcome, mostly represented by insufficient information technology infrastructures, costs and enormous volume of different information that will be integrated and delivered. To overcome these hurdles, some specific strategies should be defined and implemented, such as planning major integration of exiting information systems or developing innovative ones, combining bioinformatics and imaging informatics, using health technology assessment for assessing cost and benefits, providing interpretative comments in integrated reports, developing and using expert systems and neural networks, overcoming cultural and political boundaries for generating multidisciplinary teams and integrated diagnostic algorithms.

Long-term stability of clinically relevant chemistry analytes in pleural and peritoneal fluid [Elektronička građa] / Lara Milevoj Kopcinovic, Marija Brcic, Alen Vrtaric, Adriana Unic, Marija Bozovic, Nora Nikolac Gabaj, Marijana Miler, Jelena Culej. - Graf. prikazi.
Bibliografija: 20 jed. - Summary. - Introduction: Our aim was to investigate the stability of clinically relevant analytes in pleural and peritoneal fluids stored in variable time periods and variable storage temperatures prior to analysis. Materials and methods: Baseline total proteins (TP), albumin (ALB), lactate dehydrogenase (LD), cholesterol (CHOL), triglycerides (TRIG), creatinine (CREA), urea, glucose and amylase (AMY) were measured using standard methods in residual samples from 29 pleural and 12 peritoneal fluids referred to our laboratory. Aliquots were stored for 6 hours at room temperature (RT); 3, 7, 14 and 30 days at - 20°C. At the end of each storage period, all analytes were re-measured. Deviations were calculated and compared to stability limits (SL). Results: Pleural fluid TP and CHOL did not differ in the observed storage periods (P = 0.265 and P = 0.170, respectively). Statistically significant differences were found for ALB, LD, TRIG, CREA, urea, glucose and AMY. Peritoneal fluid TP, ALB, TRIG, urea and AMY were not statistically different after storage, contrary to LD, CHOL, CREA and glucose. Deviations for TP, ALB, CHOL, TRIG, CREA, urea and AMY in all storage periods tested for both serous fluids were within the SL. Deviations exceeding SL were observed for LD and glucose when stored for 3 and 7 days at - 20°C, respectively. Conclusions: TP, ALB, CHOL, TRIG, CREA, urea and AMY are stable in serous samples stored up to 6 hours at RT and/or 30 days at - 20°C. Glucose is stable up to 6 hours at RT and 3 days at - 20°C. The stability of LD in is limited to 6 hours at RT.

Patient-based quality control for glucometers using the moving sum of positive patient results and moving average [Elektronička građa] / Chun Yee Lim, Tony Badrick, Tze Ping Loh. - Graf. prikazi.
Bibliografija: 13 jed. - Summary. - Introduction: The capability of glucometer internal quality control (QC) in detecting varying magnitude of systematic error (bias), and the potential use of moving sum of positive results (MovSum) and moving average (MA) techniques as potential alternatives were evaluated. Materials and methods: The probability of error detection using routine QC and manufacturer’s control limits were investigated using historical data. Moving sum of positive results and MA algorithms were developed and optimized before being evaluated through numerical simulation for false positive rate and probability of error detection. Results: When the manufacturer’s default control limits (that are multiple times higher than the running standard deviation (SD) of the glucometer) was used, they had 0-75% probability of detecting small errors up to 0.8 mmol/L. However, the error detection capability improved to 20-100% when the running SD of the glucometer was used. At a binarization threshold of 6.2 mmol/L and block sizes of 200 to 400, MovSum has a 100% probability of detecting a bias that is greater than 0.5 mmol/L. Compared to MovSum, the MA technique had lower probability of bias detection, especially for smaller bias magnitudes; MA also had higher false positive rates. Conclusions: The MovSum technique is suited for detecting small, but clinically significant biases. Point of care QC should follow conventional practice by setting the control limits according to the running mean and SD to allow proper error detection. The glucometer manufacturers have an active role to play in liberalizing QC settings and also enhancing the middleware to facility patient-based QC practices.

Predictors of medical students' research degree pursuit [Elektronička građa] : a convenience poll pilot study / Ivan Buljan, Esther Park. - Graf. prikazi.
Bibliografija: 11 jed. - Summary. - Aim: The evidence about factors predicting the desire of medical graduates for pursuing research careers are inconsistent. Identification of factors which influence decision for pursuing research career would be important information to medical schools to improve research environment for students. For that reason, we performed an international survey of medical students to analyze the factors predicting research careers in medicine. Methods: An international online survey of undergraduate and graduate medical students was performed, using the using the data from Res Medica student journal database, about their research activities, future interests and plans and desire to pursue research careers. Results: In total, 486 students took the survey. Logistic regression revealed a single significant factor influencing medical students’ desire to pursue a research degree: in-creased motivation for participation in research in future (R2=0.33). Conclusion: In order to encourage students and training doctors to more readily engage in research, exposure to re-search and research participation could have an incremental value to existing research education in medical schools.

Survey on request form content and result reporting in therapeutic drug monitoring service among laboratories in Czechia and Slovakia [Elektronička građa] / Tomáš Šálek, Petr Schneiderka, Barbora Studená, Michaela Votroubková. - Graf. prikazi.
Bibliografija: 20 jed. - Summary. - Introduction: The aim of the study was to investigate current practice and policies of therapeutic drug monitoring (TDM) service requesting and result reporting in Czechia and Slovakia. Materials and methods: All 149 laboratories that measure plasma drug concentrations were given an online questionnaire during a regular external quality assessment TDM cycle. The questionnaire consisted of 17 questions. The optimal TDM practice was defined as the application of all elements (age, body weight, time of sampling, date of the first administration, time of the last dose administration, the dose, the dosing interval, the route of administration, information on reason of testing, and information on other co–administered drugs) needed for reporting a recommendation for further drug dosing (positive response to question number 16). Results: The response rate was 69%, 103 out of 149 laboratories measuring drug concentrations. Only 12% (12 out of 103 laboratories) of the laboratories implemented all elements needed for optimal TDM practice and reported a recommendation. Both paper and electronic request forms were used by 77 out of 103 (75%) laboratories. A total of 69 out of 103 laboratories (67%) specified the type of sampling tube on their request form. Cystatin C was used for prediction of renal drug elimination by 24% (25 out of 103) of participants. Conclusions: Small number of laboratories implemented all elements needed for optimal TDM practice and report a recommendation on further dosing. Further efforts in education on optimal TDM practice as well as harmonization of service are desirable.

Test results comparison and sample stability study [Elektronička građa] : is the BD Barricor tube a suitable replacement for the BD RST tube? / Sanja Mandić, Dario Mandić, Iva Lukić, Tara Rolić, Vesna Horvat, Maja Lukić, Silvija Osvald, Vatroslav Šerić. - Graf. prikazi.
Bibliografija: 21 jed. - Summary. - Introduction: The aim was to evaluate the BD Barricor tubes by comparison with the BD Rapid Serum Tubes (RST) through measuring 25 analytesand monitoring sample stability after 24 hours and 7 days.Materials and methods: Samples of 52 patients from different hospital departments were examined. Blood was collected in BD RST and BDBarricor tubes (Becton, Dickinson and Company, Franklin Lakes, USA). Analytes were measured by Beckman Coulter AU 480 (Beckman Coulter, Brea,USA), Dimension EXL (Siemens Healthcare Diagnostics, Newark, USA) and ARCHITECT i2000SR (Abbott Diagnostics, Lake Forest, USA). Between-tubecomparison for each analyte was performed, along with testing analyte stability after storing samples at 4 °C.Results: BD Barricor tubes showed unacceptable bias compared to BD RST tubes for potassium (K) (- 4.5%) and total protein (4.4%). Analyte stabilityafter 24 hours was acceptable in both tested tubes for most of analytes, except for glucose, aspartate aminotransferase (AST) and lactate dehydrogenase(LD) in BD Barricor and free triiodothyronine in BD RST sample tubes. Analyte stability after 7 days was unacceptable for sodium, K, calcium,creatine kinase isoenzyme MB, AST, LD and troponin I in both samples; additionally for glucose, alkaline phosphatase and albumin in BD Barricor.Conclusion: All analytes, except K and total protein, can be measured interchangeably in BD RST and BD Barricor tubes, applying the same referenceintervals. For most of the analytes, sample re-analysis can be performed in both tubes after 24 hours and 7 days, although BD RST tubes show better7-day analytes stability over BD Barricor tubes.

Test validation, method comparison and reference range for the measurement of β-hydroxybutyrate in peripheral blood samples [Elektronička građa] / Frank Bernhard Kraus, Marija Kocijancic, Alexander Kluttig, Beatrice Ludwig-Kraus. - Graf. prikazi.
Bibliografija: 30 jed. - Summary. - Introduction: The measurement of β-hydroxybutyrate (βOHB) concentrations is a corner stone of the diagnosis of diabetic ketoacidosis and other ketonic states. The aim of this study was to perform a validation of a peripheral blood βOHB assay (Randox) on a Roche cobas c502 analyser and to establish a βOHB reference range for the validated assay.Materials and methods: Precision, linearity and limit of detection and blank (LoD, LoB) were determined according to Clinical and LaboratoryStandards Institute (CLSI) EP05-A3, EP 06-A and EP17-A2 guidelines, using commercial control material and residual patient sample pools. As method comparison, for 190 semi-quantitative measurements of urine ketones we determined the corresponding βOHB blood concentration. The reference range was based on the CLSI C28-A3 guideline, using 304 randomly selected serum samples from population based German National Cohort (GNC) study.Results: Coefficients of variation for the validated assay ranged from 1.5% for high concentrations (3.1 mmol/L) to 6.5% for low concentrations (0.1 mmol/L). Detection capacity was LoB = 0.011 mmol/L and LoD = 0.037 mmol/L. Linearity of the assay ranged from 0.10 to 3.95 mmol/L. The agreement between the semi-quantitative urine ketone test and the βOHB blood test was moderate (Kappa = 0.66). The obtained 95% serum reference range was estimated as 0.02 to 0.28 mmol/l βOHB.Conclusions: The Ranbut βOHB assay showed good precision and analytical performance. Our results confirm that βOHB measurement in peripheral blood is indeed a preferable alternative to the semi-quantitative measurement of urine ketones.

Title does matter [Elektronička građa] : a cross-sectional study of 30 journals in the Medical Laboratory Technology category / Marina Njire Braticevic, Ivana Babic, Irena Abramovic, Anja Jokic, Martina Horvat. - Graf. prikazi.
Bibliografija: 23 jed. - Summary. - Introduction: First impression on potential readers is created by the title; therefore, authors should give importance to the title structure. The aim of this study was to establish whether articles created by a smaller number of authors and with shorter, descriptive or declarative titles gain more citations and whether article title length and number of authors correlate to the number of citations.Material and methods: A cross-sectional study on article citation data for 30 scientific journals published in 2016 in Medical Laboratory Technology field according to Web of Science database was conducted. The type of article, type of title, as well as number of words in the title and number of authors was recorded.Results: In the group of original articles (N = 2623), articles with declarative titles (N = 336, 13%) showed statistically higher number of citations in multiple comparison analysis when compared to descriptive titles (P <0.001). No correlation was found between number of citations and title word count (r = 0.07, P <0.001) nor between number of citations and number of authors in group of original articles (r = 0.09, P <0.001). Original articles with descriptive titles longer than 15 words or with more than six authors are cited more (P = 0.005 and P <0.001, respectively).Conclusion: Based on results of our study, titles do matter. Therefore, authors of original articles might want to consider including their findings in the title and having longer titles.

The top-down approach to measurement uncertainty [Elektronička građa] : which formula should we use in laboratory medicine? / Flávia Martinello, Nada Snoj, Milan Skitek, Aleš Jerin. - Graf. prikazi.
Bibliografija: 28 jed. - Summary. - Introduction: By quantifying the measurement uncertainty (MU), both the laboratory and the physician can have an objective estimate of the results’ quality. There is significant flexibility on how to determine the MU in laboratory medicine and different approaches have been proposed by Nordtest, Eurolab and Cofrac to obtain the data and apply them in formulas. The purpose of this study is to compare three different top-down approaches for the estimation of the MU and to suggest which of these approaches could be the most suitable choice for routine use in clinical laboratories. Materials and methods: Imprecision and bias of the methods were considered as components of the MU. The bias was obtained from certified reference calibrators (CRC), proficiency tests (PT), and inter-laboratory internal quality control scheme (IQCS) programs. The bias uncertainty, the combined and the expanded uncertainty were estimated using the Nordtest, Eurolab and Cofrac approaches. Results: Using different approaches, the expanded uncertainty estimates ranged from 18.9-40.4%, 18.2-22.8%, 9.3-20.9%, and 7.1-18.6% for cancer antigen (CA) 19-9, testosterone, alkaline phosphatase (ALP), and creatinine, respectively. Permissible values for MU and total error ranged from 16.0-46.1%, 13.1-21.6%, 10.7-26.2%, and 7.5-17.3%, respectively. Conclusion: The bias was highest using PT, followed by CRC and IQCS data, which were similar. The Cofrac approach showed the highest uncertainties, followed by Eurolab and Nordtest. However, the Eurolab approach requires additional measurements to obtain uncertainty data. In summary, the Nordtest approach using IQCS data was therefore found to be the most practical formula.

Bibliografija: 25 jed. - Summary. - Introduction: Urine neutrophil gelatinase-associated lipocalin (uNGAL) is a biochemical marker significant for early prediction of acute kidneyinjury in adults. However, it has not been examined sufficiently among the infant population, particularly newborns in terms of reference values.The aim of our study was to determine the concentration of uNGAL in healthy term newborns and to determine if there was a difference in uNGALconcentration according to gender, postnatal age and birth weight.Materials and methods: Our study involved 81 healthy term newborns birth (≥ 37 weeks, Apgar score ≥ 8 in the first minute after birth, CRP <5mg/L). Urine NGAL was measured using chemiluminescent microparticle immunoassay (CMIA) within 72 hours after birth, on Architect plus ci8200analyser (Abbott, Chicago, USA). Data were analysed using Statistica software.Results: The median concentration of uNGAL in the whole study group of healthy term newborns was 27.1 ng/mL (16.5-56.0 ng/mL) (newborn girls,27.1 ng/mL (15.8-47.9 ng/mL); newborn boys, 27.9 ng/mL (16.5-61.0 ng/mL), P = 0.941). Median uNGAL concentration according to postnatal ageexpressed in days was 28.2 ng/mL (11.7-57.2 ng/mL) 1st day, 28.9 ng/mL (16.5-64.2 ng/mL ) 2nd day and 23.9 ng/mL (20.2-46.6) 3rd day, P = 0.863.Regarding birth weight for newborns <3500 g, median concentration was 25.0 ng/mL (16.5-45.4 ng/mL ) and for weight ≥ 3500 g 30.6 ng/mL(16.5-64.2 ng/mL), P = 0.455.Conclusions: There were no significant difference in uNGAL concentration in relation to gender, postnatal age and birth weight.

Uvjerenje i stavovi budućih zdravstvenih radnika o učinkovitosti komplementarne i alternativne medicine [Elektronička građa] / Anamarija Jurković, Aleksandar Racz. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Sažetak ; Abstract. - Metode komplementarne i alternativne medicine (KAM) široko su rasprostranjene diljem svijeta, a u novije vrijeme raste njihova upotreba i na području Republike Hrvatske. Ovim pilot istraživanjem željelo se utvrditi stavove i uvjerenja budućih zdravstvenih radnika o pojedinim metodama komplementarne i alternativne medicine i njihovoj učinkovitosti. U tu svrhu korišten je ranije dizajniran originalni upitnik koji je primijenjen na malom uzorku. Rad je napravljen i za potrebe izrade diplomskog rada autorice s namjerom proširenja istraživanja na višoj razini školovanja koja je u tijeku. Od ukupnog broja ispitanika veliki postotak njih je barem jednom upotrijebio neku od metoda te isto tako većina ispitanika smatra kako bi se metode KAM-a trebale integrirati u obrazovni sustav, kao i s klasičnom medicinom. Kao najučinkovitije metode ispitanicu su naveli akupunkturu, kiropraktiku te razne masažne tehnike. - Methods of complementary and alternative medicine (CAM) are widespread throughout the world, and recently their use is growing in the Republic of Croatia. This pilot research aims to determine the attitudes and beliefs of future health professionals about the certain methods of complementary and alternative medicine and their effectiveness. For this purpose, an original questionnaire previously designed was used on a small sample. The paper was also made for the purpose of writing the author’s diploma thesis with the intention of expanding the research at the higher level of education that is underway. Of the total number of respondents, a large percentage of them have used one of the methods at least once, and most respondents also believe that KAM methods should be integrated into the education system, as well as with classical medicine.

Verification of automated latex-enhanced particle immunoturbidimetric D-dimer assays on different analytical platforms and comparability of test results [Elektronička građa] / Ivana Lapić, Désirée Coen Herak, Snježana Prpić, Andrea Prce, Vanja Raščanec, Renata Zadro, Dunja Rogić. - Graf. prikazi.
Bibliografija: 29 jed. - Summary. - Introduction: The aim of the study was the analytical verification of automated latex-enhanced particle immunoturbidimetric (LPIA) D-Dimerassay INNOVANCE D-dimer on Sysmex CS-5100 and Atellica COAG 360 analysers, and HemosIL D-dimer HS500 on ACL TOP 550, as well as the comparisonwith the enzyme-linked immunofluorescent assay (ELFA) on the miniVidas analyser.Materials and methods: Verification included assessment of within-run and between-run precision, bias, measurement uncertainty (MU), verificationof the cut-off, method comparison between all assessed assays, and the reference commercial ELFA VIDAS D-Dimer Exclusion II.Results: Within-run coefficients of variations (CVs) ranged from 1.6% (Atellica COAG 360) to 7.9% (ACL TOP 550), while between-run CVs rangedfrom 1.7% (Sysmex CS-5100) to 6.9% (Atellica COAG 360). Spearman’s rank correlation coefficients were >0.99 between LPIAs and ≥ 0.93 whencomparing ELFA with LPIA. Passing-Bablok regression analysis yielded constant and proportional difference for comparison of ACL TOP 550 withboth Sysmex CS-5100 and Atellica COAG360, and for miniVidas with Atellica COAG360. Small proportional difference was found between miniVidasand both Sysmex CS-5100 and ACL TOP 550. Calculated MUs using D-dimer HS 500 calibrator were 12.6% (Sysmex CS-5100) and 15.6% (Atellica COAG360), while with INNOVANCE D-dimer calibrator 12.0% (Sysmex CS-5100), 10.0% (Atellica COAG 360) and 28.1% (ACL TOP 550). Excellent agreementof results was obtained, with occasional discrepancies near the cut-off. The cut-off (0.5 mg/L FEU) was confirmed.Conclusions: The obtained results prove satisfactory analytical performance of LPIAs, their high comparability and almost equal discriminatorycharacteristics, suggesting them as a valid alternative to ELFA.

Assessment of body composition, fat mass, fat-free mass and percent of body fat among rural school children of Northeastern India [Elektronička građa] / Dali Dutta, Sarthak Sengupta. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - Recently recognized important indicators of body composition are fat mass (FM), fat-free mass (FFM) and percent body fat (PBF). The aim of this cross-sectional study is to determine body composition of the pre-adolescent children by using FM, FFM, and PBF. This study was performed using data from 584 children (281 boys and 303 girls) aged 6–10 years of Ahom descent from upper Assam state, Northeast India. Four anthropometric measurements i.e. height, weight, skinfold at triceps (TSF) and sub-scapular (SSF) were taken to calculate FM, FFM, FMI, FFMI, PBF, PBF for age (PBFZ), body mass index(BMI). Age-specific mean values of FM ranged from 2.12–4.00 kg (boys) and 2.16–4.40 kg (girls) and the agespecific mean values of FFM ranged from 14.45–23.93 kg (boys) and 14.01–23.03 kg (girls). The highest PBF value was observed at the age of 6 years for both groups of the children while the lowest value was observed at the age of 10 years and 9 years for boys and girls respectively. Sex-specific mean differences between sexes were statistically significant in SSF, PBF, FM, and FMI. For future investigations in clinical and epidemiological studies, these results are very important as they can be used to identify the risk of lower or higher adiposity and body composition using PBF, FM, and FFM. - Važni pokazatelji sastava tijela su masna tjelesna masa (FM), nemasna tjelesna masa (FFM) i postotak masnog tkiva (PBF). Cilj ove transverzalne studije je određivanje sastava tijela pomoću ovih indikatora u djece na predpubertetskom stupnju razvoja. Istraživanje je provedeno na uzorku od 584 djece (281 dječaka i 303 djevojčice) u dobi između 6 i 10 godina, iz populacije Ahom koja živi u gornjoj državi Assam, u sjeveroistočnoj Indiji. Antropometrijskim mjerenjem prikupljeni su podaci o visini i težini te kožnim naborima na nadlaktici i leđima kako bi se izračunali indeksi FM, FFM, FMI, FFMI, PBF, PBF prema dobi (PBFZ) i indeks tjelesne mase(BMI). Rezultati pokazuju vrijednosti masne tjelesne mase FM prema dobi u rasponu od 2,12–4,00 kg za dječake i 2,16–4,40 kg za djevojčice, a vrijednosti nemasne tjelesne mase FFM prema dobi u rasponu od 14,45–23,93 kg za dječake i 14,01–23,03 kg za djevojčice. Najviša vrijednost postotka masnog tkiva PBF zabilježena je u dobi od 6 godina u oba spola, dok je najniža vrijednost bila u dobi od 10 godina za dječake i 9 godina za djevojčice. Srednje razlike prema spolu su statistički značajne za kožni nabor na leđima, PBF, FM i FFM. Prikazani rezultati su važni za buduća klinička i epidemiološka istraživanja jer pokazuju da se PBF, FM i FFM mogu koristiti za identifikaciju rizika pretilosti ili neuhranjenosti i sastava tijela.

Prevalence and health adverse effects of khat chewing among college students in Jazan Region, Saudi Arabia [Elektronička građa] / Ehab Y. Elbendary, Ashraf A. Hassan, Samia F. Salem, Saif Elden Abdalla, Martina Smolić. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - Khat chewing is a social habit which has stimulatory action due to its cathinone content, but its adverse effects on health are a source of growing concern. The aim of our study is to evaluate the prevalence and health adverse effects of khat chewing among students in Jazan region in the Kingdom of Saudi Arabia (KSA). The study sample included 195 students from Applied Medical Science College, who were randomly selected and were asked through questionnaire and with a signed consent. About 5 ml of venous blood was collected in plain vacutainer tubes from 38 khat chewers and 20 non khat chewers as normal control. Serum was used to determine alanine aminotransferase (ALT), alkaline phosphatase (ALP), total and direct bilirubin, total protein, urea, creatinine, uric acid, and albumin. The sample consisted of 134 males and 61 females, with age range 19-27 years, and their mean age was 21.1 year. 40% of students were from urban area, and 81.5% of them from Jazan region. Out of 195 students, only 38 (19.5%) were found to chew khat. Biochemical results revealed highly significant differences among chewers in ALT, ALP, uric acid, and urea (p<0.005) compared to nonchewers group. There is also a significant difference in the total protein level (<0.05), while no significant differences were noticed in other biochemical traits analyzed. We concluded that the prevalence of khat chewing among students is fairly high (19.5 %), and that adverse effects of khat chewing on health are very clear, so all efforts should be contributed to solve this problem by increasing awareness of all members of the society to khat chewing risk. - Žvakanje biljke kat (Catha edulis) društveni je običaj u nekim afričkim i arapskim zemljama koji ima stimulativno djelovanje jer sadržava alkaloid katinon, iako sve više pobuđuje zabrinutost zbog štetnih učinaka na zdravlje. Cilj ove studije bio je ustanoviti prevalenciju i štetne učinke na zdravlje žvakanja kata među studentima medicinskog fakulteta u pokrajini Jazan u Saudijskoj Arabiji. Slučajno odabrani uzorak sastojao se od 195 studenata medicinskog fakulteta u Jazanu koji su ispitani pomoću upitnika uz informirani pristanak. Oko 5ml krvi izvađeno je u uzorku osoba koje uživaju kat i kontrolnom uzorku osoba koje ne žvaču kat.. Pomoću seruma određeni su u krvi alanin-aminotransferaza (ALT), alkalna fosfataza (ALP), ukupni i direktni bilirubin, ukupni protein, urea, kreatinin, mokraćna kiselina i albumin. Uzorak se sastojao od 134 muškarca i 61 žene u dobi od 19 do 27 godina čija je srednja dob bila 21,1 godina, a 40% studenata bilo je porijeklom iz grada, a 81,5% iz drugih mjesta u pokrajini Jazan. Utvrđeno je da je 38 (19,5%) studenata uživalo kat. Rezultati biokemijske analize pokazali su da postoje statistički značajne razlike između studenata koji žvaču kat i kontrolne skupine u parametrima ALT, ALP, mokraćnoj kiselini i urei (p<0,005). Značajna razlika utvrđena je također za ukupni protein (p<0.05), dok za druga biokemijska obilježja razlike nisu bile značajne. Studija ukazuje na jasne štetne učinke žvakanja kata na zdravlje te na potrebu ulaganja napora za podizanje svijesti svih članova društva o rizicima žvakanja kata.

Monitoring emisija onečišćujućih tvari na području grada Tuzle [Elektronička građa] / Emir Hodžić, Elma Alić, Emir Horozić. - Graf. prikazi.
Bibliografija: 34 jed. - Sažetak ; Summary. - Onečišćenje zraka se sve više smatra značajnim rizikom po zdravlje stanovništva. Uslijed rada industrije, velike koncentracije prometa i individualnih ložišta, na području grada Tuzle već je dulje vrijeme prisutan problem onečišćenja zraka. Tvari koje onečišćuju okoliš predstavljaju rizik za zdravlje ljudi i drugih živih bića, a onečišćenje zbog sagorijevanja fosilnih goriva je na vodećem mjestu crne ljestvice prijetnji za zdravlje. Onečišćenost okoliša može uzrokovati niz bolesti, poput astme, alergija, raznih oblika raka, bolesti srca i krvožilnog sustava, problema s plodnošću, neuroloških problema i slično. U ovom radu prikazani su rezultati monitoringa emisije polutanata u razdoblju od 1. 1. 2019. do 31. 12. 2019. godine. Proveden je monitoring zraka za polutante: sumporov dioksid (SO2), dušikov dioksid (NO2), ugljikov monoksid (CO), ozon (O3) i lebdeće čestice PM2,5, na tri lokacije u Tuzli. Rezultati ukazuju na to da je tijekom sezone grijanja, odnosno zimskih mjeseci kvaliteta zraka u urbanom području grada Tuzle vrlo loša. Najveća koncentracija sumporova dioksida zabilježena je u prosincu na mjernoj stanici Bukinje i iznosila je 271,7 µg m–3, također u istom mjesecu, na mjernoj stanici Skver zabilježena je koncentracija lebdećih čestica PM2,5 od 153,2 µg m–3. - Air pollution is increasingly considered a significant risk to human health. Due to industrial activity, individual fireboxes, and the high traffic concentration, the problem of air pollution has long been present in the Tuzla area. Environmental pollutants cause serious harm to humans and all living things, and pollution from fossil fuel combustion is at the forefront of the black scale of health threats. Environmental pollution can cause a number of diseases such as asthma, allergies, various cancers, heart and circulatory system diseases, fertility problems, neurological problems. This paper presents the results of monitoring pollutant emissions in the period from Jan 1 to Dec 31, 2019, and the harmful effects of polluted air on the human body. Monitoring at three locations in Tuzla was carried out for the following air pollutants: sulphur dioxide (SO2), nitrogen dioxide (NO2), carbon monoxide (CO), ozone (O3) and PM2.5. The results showed that, during the heating season (winter months), the air in the urban area of Tuzla was heavily polluted; the highest concentration of sulphur dioxide was recorded in December at the measuring station Bukinje, which amounted to 271.7 µg m–3. In the same month, the measuring station Skver recorded a concentration of particulate matter PM2.5 of 153.2 µg m–3.

Poremećaj u prehrani - pretilost [Elektronička građa] : prehrambene navike, tjelesna aktivnosti i samoprocjena BMI u Hrvatskoj / Dijana Maslarda, Natalija Uršulin-Trstenjak, Leonardo Bressan. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Sažetak ; Abstract. - Pretilost je danas jedan od vodećih zdravstvenih problema u svijetu. Svrha ovog istraživanja je bila istražiti životne navike ispitanika, vezane uz navike prehrane te tjelovježbi. Isto tako svrha je bila uvidjeti koliko su ispitanici upoznati sa pojmom i problemom pretilosti kao i navika koje povećavaju rizik od pretilosti. U istraživanju je sudjelovalo 678 ispitanika u dobi od 18 do 30 godina koji su dobrovoljno ispunili anketu koju smo sami osmislili i kreirali. Anketa se sastojala od 11 pitanja u kojima su bili ponuđeni odgovori te se ispitanik odlučio na jedan ili više odgovora ovisno o strukturi pitanja. Od 678 ispitanika, anketu je ispunilo 86,4 % žena i 13,6% muškaraca uglavnom u dobi od 20 – 25 godina pretežito sa srednjom stručnom spremom. 99,0% ispitanika je odgovorilo da zna što je pretilost. Na pitanje koliko često se bavite tjelesnom aktivnošću 28,6% ispitanika je odgovorilo nekoliko puta mjesečno dok je 14,7% ispitanika odgovorilo jednim tjedno. Od 678 osoba koje su riješile anketu njih 82 imaju ITM više od 30 ukupno 12,0%. Rezultati ovog istraživanja nam ukazuju na veliki problem glede tjelesnih aktivnosti. Sjedilački i užurbani način života prouzrokovao je nedostatak volje i vremena za bavljenje tjelesnim aktivnostima koje su od presudnih čimbenika u prevenciji pretilosti. Isto tako nepravilan način prehrane, česta konzumacija brze hrane kao i hrane uzgojene na umjetan način je korak bliže ka poremećajima prehrane i pretilosti. - Today, obesity is one of the leading health problems in the world. The purpose of this study was to investigate the lifestyle of the examinees, related to nutrition and physical exercise habits. Also, the purpose was to find out how many subjects are familiar with the concept and problem of obesity as well as habits that increase the risk of obesity. The survey involved 678 respondents aged 18 to 30 who voluntarily completed the survey we have designed and created. The survey consisted of 11 questions in which the answers were offered and the respondent decided on one or more responses depending on the structure of the question. Of the 678 respondents, 86.4% of women and 13.6% of men were mostly surveyed at the age of 20-25, mostly with secondary education. 99.0% of respondents responded to knowing what obesity was. When asked how often they deal with physical activity, 28.6% of respondents answered several times a month, while 14.7% responded once a week. Out Of the 678 persons who settled the survey, 82 had ITMs more than 30 total 12.0%. The results of this research point to a big problem with regard to physical activity. The sedentary and harsh wayof life has caused a lack of willingness and time to engage in physical activities that are crucial factors in the prevention of obesity. The same improper diet, frequent consumption of fast food as well as artificially breed food is a step closer to eating disorders and obesity.

Utjecaj onečišćenja zraka na razvoj astme [Elektronička građa] / Dajana Kučić Grgić, Klara Karadakić, Stefania Majdandžić, Lucija Štajduhar, Vesna Ocelić Bulatović. - Ilustr., graf. prikazi.
Bibliografija: 38 jed. - Sažetak ; Summary. - Onečišćenje zraka globalni je problem te se smatra jednim od najčešćih nealergijskih uzročnika astme. Utjecaj onečišćenja zraka na pojavu astme, posebno kod djece, tema je mnogih znanstvenih istraživanja naročito na istoku svijeta s obzirom na problem onečišćenja s kojim se suočava. Ovisno o prostoru djelovanja onečišćenog zraka kojemu je čovjek izložen postoje različite onečišćujuće tvari. Tako onečišćenje zraka u vanjskom prostoru karakterizira izrazita prisutnost ozona, O3, lebdećih čestica, PM2,5 i PM10 te sumporova dioksida, SO2, dok zatvoreni prostori obiluju prisutnošću formaldehida, CH2O, dušikova dioksida, NO2 i hlapljivih organskih spojeva, VOC. Uz kontrolirano liječenje, velika pažnja se usmjerava i na klimatsko liječenje astme. - Air pollution is a global problem and is considered one of the most common non-allergen triggers of asthma. The impact of air pollution on the appearance of asthma, especially in children, is the subject of many scientific researches, especially in the eastern world due to the problem of pollution it is facing. There are different pollutants depending on the area of activity in which a person is exposed. Thus, contamination of outdoor air is characterized by the marked presence of ozone, O3, fine particles, PM2.5 to PM10 and sulphur dioxide, SO2, while indoor air with the presence of formaldehyde, CH2O, nitrogen dioxide, NO2, and volatile organic compounds, VOCs. With controlled treatment, great attention is focused on climatic treatment of asthma.

Alkoholizam kod mladih [Elektronička građa] = Alcoholism in youth people / Matija Spudić, Radoslav Kosić. - Graf. prikazi.
Bibliografija: 11 jed. - Sažetak ; Abstract. - Introduction: Alcohol consumption among young people is a common activity that needs to be given considerable attention, and because of the consequences that can cause in the life of a young person. Research goal: Goal is to examine the incidence of observation and hospitalization for alcohol intoxication in adolescents and young adults in Karlovac County. Participants and Methods: The data used in this paper were collected from the Hospital Information System of the General Hospital Karlovac for the period from 2013 to 2018. Descriptive and inferential statistics were used for the statistical processing of the obtained data. IBM SPSS Statistics (version 20) was used. Results: The conducted study showed that there was a statistically significant difference in the number of male and female patients admitted to the hospital between 2013 and 2018: 173 (72.7%) male and 65 (27.3%) female patients. The average age of all patients is 19. The largest number of patients was admitted due to alcohol consumption in 2015 (22.3%) and 2016 (20.2%). From 2016 to 2018 there was a decrease in the number of admissions. Most patients were admitted to OHBP (51%), followed by patients admitted to the Department of Psychiatry (40.2%) and the Department of Pediatrics (8.7%). The highest number of patients was diagnosed with F10.0 (65.1%), followed by patients diagnosed with F10 (28.6%). The lowest number of patients was diagnosed with F10.1 (3.4%) and F10.2 (2.9%), which is expected given that these are young people who, most often, are not recidivists but also due to the avoidance of stigma. It is noted that the number of patients discharged home from hospital increases with age, while the number of hospitalized patients decreases with age.

Analiza sadržaja soli u kruhu i pecivu nakon primjene novoga nacionalnog pravilnika o žitaricama i proizvodima od žitarica [Elektronička građa] / Dario Lasić, Filip Vujnović, Željka Kuharić, Ivana Prskalo, Marijan Benić, Vanja Vasiljev. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Sažetak ; Abstract. - Prekomjerni unos soli ključni je čimbenik u epidemiji prehipertenzije/hipertenzije. Hrvatska je 2014. objavila Strateški plan za smanjenje prekomjernog unosa kuhinjske soli u Republici Hrvatskoj 2014. – 2019. prema preporukama Svjetske zdravstvene organizacije te je preporučena količina soli 5 grama na dan (2 g natrija), dok prema najnovijim istraživanjima stanovnici u Hrvatskoj i dalje prosječno dnevno unose dvostruko više od preporučene dnevne količine (11,6 g na dan). U eksperimentalnom dijelu ovog istraživanja u slučajno odabranim uzorcima iz maloprodaje analitički je ispitan sadržaj natrija (te računski ukupni sadržaj soli) u više vrsta pekarskih proizvoda (kruh, peciva). U tu svrhu, primjenom sofisticirane analitičke opreme ICP-MS (induktivno spregnuta plazma s masenom spektrometrijom) utvrđene su količine natrija u različitim vrstama kruha, kruščića i peciva te uspoređene sa zahtjevima nacionalne regulative o maksimalno dozvoljenom sadržaju natrija u kruhu koji propisuje maksimalno 1,4 %. Prosječna vrijednost svih uzoraka iznosi 1,46 g / 100 g, što prelazi dozvoljenu količinu. Rezultati ukazuju na to da se svi proizvođači još uvijek nisu prilagodili odredbama pravilnika te da ne zadovoljavaju zahtjeve premašujući dozvoljene količine natrija, odnosno soli u kruhu i pecivima. - Excessive salt intake is a key factor in the epidemic of prehypertension/hypertension. In 2014 the Republic of Croatia has published a National Strategic Plan for Reducing Excessive Salt Intake in the Republic of Croatia 2014-2019, according to the recommendations of the World Health Organization. The recommended intake of salt is 5 grams/day (2 grams of sodium), while according to the latest research, the population in Croatia on average still consume twice the recommended daily amount (11.6 grams/day). In the experimental part of this study, the sodium content (and the calculated total salt content) in several types of bakery products (bread, pastry) was analysed in randomly selected retail samples. For this purpose, using sophisticated analytical equipment ICP-MS (Inductively Coupled Plasma Mass Spectrometry), the amount of sodium in different types of bread, bakery products and pastry has been determined and compared with the requirements of the national regulation on maximum permitted sodium content in bread, which prescribes a maximum of 1.4 %. The average value of all samples is 1.46 grams/100 grams, which exceeds the permitted amount. The results indicate that not all manufacturers have yet complied with the regulations and that they do not meet the requirements exceeding the permitted amounts of sodium, i.e. salt in bread and pastries.

Governance in/of cancer care and stewardship in cancer control [Elektronička građa] : creation of definitions / Marjetka Jelenc, Maruška Vidovič, Edit Marosi, Peter Nagy, Antonio Federici, Mateja Lamovšek, Tit Albreht. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - In the literature in the field of cancer care, especially in the literature concerning national cancer control programmes, the terms governance and stewardship in/of cancer care are used, but usually not explained or defined. Therefore, we planned a systematic literature review in order to find the definitions of the terms governance and stewardship in/of cancer care. It was planned to create new definitions of the mentioned terms in case of unsuccessful finds. A literature review using PubMed, Google and MeSH as well as an opportunistic search for extra articles and chapters from books and grey literature was performed. Most of the found and analysed articles did not give exact explanation of the terms governance/stewardship in/of cancer care or they cited older articles (published before the year 2000) where the terms are used mostly in the field of clinical governance or in the completely other fileds, mostly banking, economy, religion or spirituality. Therefore, it was decided in the working group of experts from different European countries collaborating within in the work package Governance of integrated and comprehensive cancer care in the frame of the Innovative Partnership for the Action Against Cancer Joint Action project on cancer to create new definitions which we are presenting for the first time. The new definitions will facilitate the understanding of the leadership tasks in the area of cancer care and cancer control and will be particularly useful in the field of cancer programmes. - U literaturi na području skrbi o raku, posebno u literaturi koja se odnosi na nacionalne programe za rak, pojmovi upravljanje u sustavu skrbi o raku/nadzor u kontroli raka često se koriste, ali obično nisu objašnjeni ili definirani. Stoga smo pretražili literaturu kako bismo pronašli definicije pojmova upravljanje u sustavu skrbi o raku/nadzor u kontroli raka. Planirano je bilo stvaranje novih definicija spomenutih pojmova u slučaju neuspješnih nalaza. Provedeno je pretraživanje literature pomoću PubMeda, Googlea i MeSH-a, kao i oportunističko traženje dodatnih članaka i poglavlja iz knjiga i sive literature. Većina pronađenih i analiziranih članaka nije dala točno objašnjenje pojmova upravljanje u sustavu skrbi o raku/nadzor u kontroli raka ili su citirali starije članke (objavljene prije 2000. godine) gdje se pojmovi uglavnom koriste u području kliničkog upravljanja ili u potpunosti druge sfere, uglavnom bankarstva, gospodarstva, religije ili duhovnosti. Stoga je u radnoj skupini stručnjaka iz različitih europskih zemalja koji surađuju u okviru radnog paketa Upravljanje integrirane i razumljive skrbi o raku u okviru projekta Inovativno partnerstvo za akciju protiv raka dogovoreno da se stvore nove definicije koje u članku predstavljamo prvi puta. Nove će definicije olakšati razumijevanje zadataka upravljanja u području raka, a bit će posebno korisne u području nacionalnih programa protiv raka.

Health care documentation management in hospital conditions [Elektronička građa] / Amer Ovčina, Selveta Mušanović, Ernela Eminović, Nada Spasojević, Amela Hajdarević, Jasmina Marušić. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Summary ; Sažetak. - Healthcare documentation or nursing documentation as often used in practice is the name of an indispensable part of a patient’s medical documentation, and documentation is an integral part of a nurse’s daily work. Documenting health care in the hospital means recording data on all procedures performed, during the entire health care process for the individual, all for the purpose of systematic monitoring, planning and evaluation of the quality of health care. Nursing documentation serves as a means of communication between the team and is of great importance for the quality and continuity of health care. AIMS: 1 - To determine the existence of health care documentation in hospital health care institutions; 2 - Examine the importance and purpose of documenting health care among nurses-medical technicians; 3 - Examine the practice of nurses-medical technicians in the process of administering health care; 4 - Present quality indicators that are monitored and analyzed through health care documentation; 5 - Compare the obtained results in two examined areas. METHODS: This research was conducted in two geographically separate areas of Sarajevo and Travnik. The study involved 210 respondents, 147 nurses-technicians employed at the Clinical Center of the University of Sarajevo and 63 nurses-technicians employed at the General Hospital in Travnik. Data collection for research was carried out by exploratory and descriptive method. An original authorized questionnaire was used for the descriptive research. The questionnaire was made available to respondents in the electronic form trough Google Forms. The anonymity of the respondents was fully guaranteed. The survey was conducted in the period from July 15- August 15, 2019. RESULTS: At the Clinical Center of the University of Sarajevo (CCU), 98% of respondents use health care documentation forms on a daily basis, and at the General Hospital Travnik 77.8% of respondents. - Dokumentacija zdravstvene njege ili sestrinska dokumentacija, kako se često naziva u praksi, neizostavan je dio medicinske dokumentacije pacijenta, a dokumentiranje je sastavni dio svakodnevnoga sestrinskog posla. Dokumentiranje zdravstvene njege u bolnici podrazumijeva zapisivanje podataka o svim provedenim postupcima tijekom cjelokupnog procesa zdravstvene njege za pojedinca, a sve u svrhu sustavnog praćenja stanja te planiranja i vrednovanja kvaliteta zdravstvene njege. Sestrinska dokumentacija služi kao sredstvo komunikacije između tima i od velike je važnosti za kvalitetu i kontinuitet zdravstvene njege. CILJEVI RADA: 1. Utvrditi postojanje dokumentacije zdravstvene njege u bolničkim zdravstvenim ustanovama. 2. Ispitati praksu medicinskih sestara/tehničara u procesu administriranja zdravstvene njege. 3. Prikazati indikatore kvalitete koji se prate i analiziraju putem dokumentacije zdravstvene njege. 4. Komparirati dobivene rezultate u dva ispitivana područja. METODE RADA: Ovo istraživanje provedeno je na dva geografski odvojena područja, u Sarajevu i Travniku. U istraživanju je sudjelovalo 210 ispitanika, i to 147 medicinskih sestara/tehničara zaposlenih u Kliničkom centru Univerziteta u Sarajevu i 63 medicinske sestre / medicinska tehničara zaposlena u Općoj bolnici u Travniku. Prikupljanje podataka za istraživanje provedeno je deskriptivnom metodom. Za deskriptivno istraživanje primijenjen je originalni autorski upitnik. Upitnik je ispitanicima bio dostupan u elektroničkom obliku u internetskoj aplikaciji Google Forms. Anonimnost ispitanika bila je u potpunosti zajamčena. Istraživanje je provedeno u periodu od 15. srpnja do 15. kolovoza 2019. REZULTATI ISTRAŽIVANJA:U Kliničkom centru Univerziteta u Sarajevu 98 % ispitanika svakodnevno upotrebljava obrasce dokumentacije zdravstvene njege, a u Općoj bolnici Travnik 77,8 % ispitanika.

Komunikacija u zdravstvenom timu [Elektronička građa] = Communication in the health care team / Anela Ležaić.
Bibliografija: 47 jed. - Sažetak ; Abstract. - Dobra komunikacija između medicinskih sestara, liječnika i bolesnika neophodna je za uspješan ishod individualne skrbi za svakog bolesnika. Cilj je da se, uz poboljšanu percepciju timskog rada, medicinske sestre i liječnici osjećaju ugodnije u međusobnoj interakciji i sudjelovanju u zajedničkom odlučivanju. U konačnici je važno i da podržavaju kulturu sigurnosti za bolesnike te članove zdravstvenog tima. Učinkovit zdravstveni tim osigurava medicinskim sestrama manje izgaranja na radnom mjestu. Kvalitetna komunikacija pomaže u organizaciji jasne, točne i dosljedne zdravstvene službe, jamčeći zadovoljstvo bolesnika i zaštitu medicinskih sestara. Komunikacija između članova tima ključna je za postojanje tima. Članovi promiču izražavanje inovativnih prijedloga, korištenje poboljšanih radnih postupaka i jasnu raspravu o problemima i zajedničkim zadacima. Liječnik i medicinska sestra imaju dobro definiran djelokrug rada te djeluju kao partner u zdravstvenom timu. Najučinkovitiji su timovi oni čiji se članovi razlikuju prema znanju i informacijama koje posjeduju i jedinstveni su u vrednotama koje zagovaraju. Neučinkovit timski rad prepoznat je kao glavni čimbenik koji doprinosi smanjenju sigurnosti bolesnika. Stoga je jačanje timskog rada diljem svijeta ključno za poboljšanje sigurnosti bolesnika. Potrebno je istaknuti da neučinkovitu komunikaciju između članova zdravstvenog tima opažaju i bolesnici. U radu su prikazani oblici komunikacije i prednosti timskoga rada. Važnost komunikacije u zdravstvu prikazana je putem dobivenih rezultata provedenih istraživanja drugih autora. - Good communication between nurses, doctors, and patients is essential for a successful outcome of individual care for each patient. The main goal of successful communication and improved perception of teamwork for nurses and physicians is to feel more comfortable interacting with each other and participating in joint decision making. It is also very important that they support a culture of safety for patients and members of the health care team. An efficient health care team provides nurses less burnout syndrome in the workplace. Quality communication is a key for organizing a clear, accurate, and consistent health service, guaranteeing patients’ satisfaction and the protection of nurses. Communication between team members is necessary to team existence. It is important for members to suggest innovative proposals, the use of improved working procedures, and a clear discussion of problems and common tasks. The doctor and nurse have a well-defined scope of work and they act as a partner in the health care team. The most effective teams are those whose members differ in the knowledge and information they have and are unique in the values they advocate. Ineffective teamwork has been identified as a major contributing factor to reduced patient safety. Therefore, strengthening teamwork around the world is the key to improving patient safety. It should be noted that ineffective communication between members of the health care team is also spotted by patients. The paper presents the forms of communication and the advantages of teamwork. The importance of communication in health care is shown through the obtained results of research conducted by other authors.

Način dokumentiranja disanja plućnih pacijenata na Klinici za plućne bolesti Jordanovac [Elektronička građa] = The way of documenting the breathing of patients with pulmonary diseases at the Clinical Centre for Pulmonary Diseases Jordanovac / Lidija Kozonić, Slađana Režić. - Graf. prikazi.
Bibliografija: 11 jed. - Sažetak ; Abstract. - Uvod: Najvažniji je proces ljudskog organizma disanje. Disanje se izvodi nesvjesno i voljno, a kontroliraju ga skupine živaca koji pripadaju voljnom sustavu te skupina autonomnih živaca. Disanje ukazuje na niz poremećaja i zbog toga je važno pratiti i bilježiti disanje pacijenata u bolnici. Cilj: Cilj je rada utvrditi način dokumentiranja disanja kod plućnih pacijenata na dvama odjelima Klinike za plućne bolesti Jordanovac. Metode i ispitanici: Retrospektivnom je analizom sestrinske dokumentacije uključeno 60 pacijenata koji su se liječili na dvama odjelima Klinike za plućne bolesti Jordanovac. U tu svrhu izrađena je tablica u koju su se upisivali podaci vezani za dokumentiranje disanja. Rezultati: Rezultati pokazuju da postoje razlike u dokumentiranju disanja između dvaju analiziranih odjela Klinike za plućne bolesti Jordanovac. Medicinske sestre s Odjela intenzivne skrbi u visokom postotku bilježe disanje prilikom prijema pacijenata na Odjel (87 %). Svakodnevno se višekratno bilježi disanje u obrascu vitalnih znakova te se prati disanje putem saturacije i plinske analize arterijske krvi. Medicinske sestre s Odjela za opstruktivne bolesti pluća bilježe disanje pacijenata prilikom prijema u 53 % slučajeva, dok se bilježenje disanja u obrascu vitalnih znakova ne bilježi, a u samo 43 % slučajeva prati se saturacija. Zaključak: Analizom je utvrđeno postojanje razlike u dokumentiranju disanja između dvaju odjela Klinike za plućne bolesti Jordanovac. Razlike se odnose na bilježenje disanja u sestrinskoj anamnezi prilikom prijema pacijenata na odjele, bilježenje disanja u obrascu vitalnih znakova, praćenju disanja mjerenjem saturacije i vađenjem plinske analize arterijske krvi. Rezultati pokazuju značajne razlike te upućuju na potrebu dodatne edukacije medicinskih sestara.

SULE, Zdenka
Nurse in a team [Elektronička građa] : cross-sectional studyof nurses' opinions on physician-nurse relationship / Zdenka Sule, Ana Marušić. - Graf. prikazi.
Bibliografija: 14 jed. - Summary. - Background: For a long time, physicians have considered themselves superior to nurses, whose duty has been to carry out physicians’ orders regardless of their professional and scientific background and efficiency. Nowadays, a more professional approach to nursing profession emphasizes their professional autonomy. There are not many studies of the physician-nurse relationship that lead nurses to obedience towards physicians and their demands. We investigated nurses reactions to situations in which they are asked to fulfil physicians’ demands even when such actions are against their knowledge, beliefs or experience. Methods: We included 94 nurses, employees of the University Hospital Centre Split, Croatia in a questionnaire survey. The questionnaire included demographic data, attitudes toward their work, self-esteem scale and 3 case vignettes in which participants submitted their answers on visual analogue scales. The first case vignette was related to the nurses’ knowledge, the second one to their experience, and the third one to their professional beliefs. Results: Nurses with a high level of self-esteem were more likely to disagree with a subordinate physician-nurse relationship. Also, when it comes to their own opinion and potential, nurses were willing to carry out the demands of the physicians even when it is contrary to their knowledge, experience and beliefs. Conclusion: Even though they are aware of their autonomy and their prerogative to make their own decisions and act based on their professional competences, nurses seem to be prone to yielding to physicians’ demands in order to be accepted by their associates and to avoid any possible conflicts, even when such demands are not scientifically justified.

Opća informiranost i stavovi medicinskih sestara o metodama prenatalne genetičke dijagnostike [Elektronička građa] = General awarness and attitudes of nurses about methods of prenatal genetic diagnostics / Stella Stanojević, Anto Čartolovni.
Sadrži i: Anketni upitnik na str. 133-134. - Bibliografija: 15 jed. - Sažetak ; Abstract. - Uvod: Prenatalna genetička dijagnostika obuhvaća dijagnostičke postupke kojima ispitujemo bolesti ili patološka stanja kod ploda. Možemo ju podijeliti na dvije vrste metoda: invazivnu i neinvazivnu. S obzirom na to da invazivne metode u značajnoj mjeri mogu naštetiti i majci i plodu, posljednjih desetljeća ubrzano se razvijaju neinvazivne metode. One su sigurnije, no unatoč tome, i jedne i druge predstavljaju značajne etičke izazove. Medicinske sestre u mnogočemu mogu pridonijeti razvoju prenatalne dijagnostike putem pružanja informacija roditeljima, upoznavanja roditelja s dijagnostičkom procedurom, suosjećanja s njima, pružanjem podrške u rješavanju etičkih dilema s kojima se roditelji susreću. Cilj rada bio je ispitati i utvrditi opću informiranost medicinskih sestara o metodama prenatalne genetičke dijagnostike te ispitati stavove medicinskih sestara o njihovoj ulozi u procesu prenatalne dijagnostike. Metode: Uzorak ispitanika činile su medicinske sestre koje rade u Kliničkom bolničkom centru Sestre milosrdnice i Općoj županijskoj bolnici Našice na Odjelu ginekologije i porodništva. U istraživanju je sudjelovalo 115 ispitanika. Korišten je upitnik koji se sastoji od 29 pitanja. Rezultati: Ispitanici su pokazali osrednje znanje o prenatalnoj dijagnostici. Smatraju da bi trudnice trebale obavljati neinvazivne testove, da su prenatalne metode pouzdane te da medicinske sestre mogu pomoći u prihvaćanju informacije o anomalijama djeteta. S druge strane, ispitanici se ne slažu s tvrdnjom da bi medicinske sestre trebale davati savjete trudnicama te da su invazivne metode opasne. Rasprava: Istraživanje ukazuje na potrebu dodatne edukacije medicinskih sestara kako bi mogle djelovati na području prenatalne dijagnostike i biti uključene u genetička savjetovališta. Zaključak: Razvojem prenatalne genetičke dijagnostike dolazi do pojave novih etičkih dvojbi koje postaju sve veći izazov medicinskim sestrama.

Quality improvement project [Elektronička građa] : reducing non-conformities of the samples for haemostasis testing in a secondary healthcare centre through the nurses' education in phlebotomy / Patricija Banković Radovanović. - Graf. prikazi.
Bibliografija: 29 jed. - Summary. - Introduction: Poor compliance to the current guidelines and lack of knowledge among nurses about proper blood sampling is set as the study hypothesis. Here is presented a quality improvement project with following aims: a) to identify the most prevalent non-conformity of the samples for haemostasis testing, b) to identify the cause of sample non-conformity, c) to perform corrective action(s) and d) to assess the effectiveness of the corrective action(s). Materials and methods: The rate of non-conformity of samples collected for haemostasis tests was established for hospital wards with inpatients. Phlebotomy practice was audited throughout anonymous questionnaire among hospital’s nurses who perform phlebotomy. Education about blood sampling was performed as a 1-hour lecture in different small groups each working day within one month. Education effectiveness was assessed through the evaluation of sample quality and is considered effective if more than half of the hospital wards significantly reduced their sample non-conformities rate. Results: Clotted sample constituted 84% of sample non-conformities. The questionnaire revealed nurses’ poor knowledge in phlebotomy. There was no difference in nurses’ knowledge regarding the level of education or work experience. Reduction in sample non-conformities was observed in 7 out of 9 wards 4 months after education; this improvement was statistically significant for 5 wards. Conclusion: Clotted sample as the most prevalent non-conformity of the samples for haemostasis testing is caused by the lack of knowledge of the nurses in several parts of the phlebotomy process. Specific education of the motivated personnel in small groups was successful and long-term effective.

Strategies to improve academic motivation among nursing students [Elektronička građa] = Strategije poboljšanja akademske motivacije među studentima sestrinstva / Leona Cilar, Marija Spevan. - Graf. prikazi.
Bibliografija: 41 jed. - Abstract ; Sažetak. - Introduction: Academic motivation of nursing students is a broad concept that has an impact on academic success, education and personal satisfaction. Motivation to study often decreases with years of study, thus it is important to find out effective strategies for motivating nursing students. Methods: A scoping review was conducted in 2020 to determine the scope and body of literature on strategies for motivating nursing students. A literature search was performed in four international databases (PubMed, Medline, Science-Direct and Google Scholar) using inclusion and exclusion criteria. The literature search and analysis are shown using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations. Results: Out of 560 identified studies, a total of 14 studies were included in the final analysis. Most of the identified studies were quasi-experimental studies (n=8; 57.14 %) exploring the effectiveness of existing strategy. Strategies that showed positive effects in raising nursing student’s academic motivation are gamification, mobile applications, forums, problem-based learning, and other specific strategies. Discussion: It is evident that new strategies have positive impact on nursing student’s academic motivation. Nevertheless, there is a need for further research and testing before the process of implementing those strategies in specific learning environment. Conclusion: There is a constant need for education of future nurses. To ensure appropriate nurses’ knowledge and skills, academic motivation is needed. - Uvod: Akademska motivacija studenata sestrinstva širok je pojam koji utječe na akademski uspjeh, obrazovanje i osobno zadovoljstvo. Motivacija za učenje često opada s godinama studija, stoga je važno pronaći učinkovite strategije za motiviranje studenata sestrinstva. Metode: Proveden je opsežni pregled u 2020. godini kako bi se utvrdio opseg i sadržaj literature o strategijama za motiviranje studenata sestrinstva. Pretraživanje literature provedeno je u četirima međunarodnim bazama podataka (PubMed, Medline, ScienceDirect i Google Scholar) pomoću kriterija za uključivanje i isključivanje. Pretraživanje i analiza literature prikazani su pomoću preporučenih stavki izvještavanja za preporuke sustavnih pregleda i metaanaliza (PRISMA). Rezultati: Od 560 identificiranih studija, u konačnu analizu uključeno je ukupno 14 studija. Većina identificiranih studija bile su kvazieksperimentalne studije (n = 8; 57,14 %) koje su istraživale učinkovitost postojeće strategije. Strategije koje su pokazale pozitivne učinke na podizanje akademske motivacije učenika sestrinstva su gamifikacija, mobilne aplikacije, forumi, učenje temeljeno na problemima i druge specifične strategije. Rasprava: Očigledno je da nove strategije imaju pozitivan utjecaj na akademsku motivaciju studenata sestrinstva. Ipak, postoji potreba za daljnjim istraživanjima i ispitivanjima prije procesa implementacije tih strategija u određeno okruženje za učenje. Zaključak: Postoji stalna potreba za obrazovanjem budućih medicinskih sestara. Da bi se osigurala odgovarajuća znanja i vještine medicinskih sestara, potrebna je akademska motivacija.

Stupanj zadovoljstva medicinskih sestara u izvršavanju radnih zadataka [Elektronička građa] = Satisfaction of nurses in performing work tasks / Luka Jurić, Štefica Mikšić. - Graf. prikazi.
Bibliografija: 34 jed. - Sažetak ; Abstract. - Uvod: Stupanj zadovoljstva izvršavanja radnih zadataka definira se ugodnim osjećajem koji proizlazi iz percepcije da nečiji posao ispunjava ili omogućava ispunjenje važnih poslovnih vrijednosti pojedinca. On utječe na stupanj kvalitete rada, učinkovitost u radu i važan je dio sestrinskog profesionalnog života. Cilj: U istraživanju se željelo ispitati utječu li međuljudski odnosi, organizacija rada, osjećaj sigurnosti na poslu, visina plaće, mogućnost napredovanja i komunikacija na zadovoljstvo izvršavanja radnih zadataka medicinskih sestara i tehničara. Metode: Provedeno je presječno istraživanje pomoću anonimnog anketnog upitnika u kojemu je sudjelovalo 67 medicinskih sestara i tehničara koji rade na kirurškim odjelima te u operacijskim salama. Rezultati: Iz rezultata je vidljivo da su zaposlenici kirurških odjela i operacijskih sala u Kliničkom bolničkom centru Sestre milosrdnice nezadovoljni organizacijom rada, ali su djelomično zadovoljni radnim zadacima. Prevladava zadovoljstvo osjećajem sigurnosti na poslu te sigurnosti zaposlenja. U ispunjavanju radnih zadataka vrlo je bitno zadovoljstvo odnosom s nadređenim, mogućnost napredovanjate zadovoljstvo s bliskim suradnicima. Zaključak: Zaposlenici na kirurškim odjelima te u operacijskim salama u Kliničkom bolničkom centru Sestre milosrdnice djelomično su zadovoljni izvršavanjem radnih zadataka. - Introduction: Aim of this research is to determine the contentment rate at performing nurses’ work assignments, the quality rate of the medical care, the causal relation and the effect on efficiency and productiveness of nurses’ work at surgical wards and in operating rooms. Methods: The research was conducted through an anonymous questionnaire in University Hospital Center Sestre Milosrdnice. In total, 67 nurses participated in a cross-sectional study. Results: The results reveal that the employees at the surgical wards and the operating rooms in University Hospital Center Sestre Milosrdnice are not contented with the organization of work, but they are contented with the work assignments. The feeling of security at work and the security about the workplace prevails. Concerning fulfilling the work assignments, the relationship with the superiors is very important, the possibility of promotion and the contentment about the relationship with the co-workers. Conclusion: We can conclude that the employees at surgical wards and operating rooms in University Hospital Center Sestre Milosrdnice are partially contented with performing given assignments which is influenced by the relationship with superiors and close co-workers. Contrary to that, their contentment is the least influenced by the organization of work.

Survey of patient satisfaction with radiological services in public and private health facilities in Kano [Elektronička građa] / Lydia A. Gana, Mustapha Barde, Chigozie I. Nwobi, Joseph D. Zira, Musa G. Lalai, Mohammad Sidi, Emmanuel I. Richard. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - Background: Patient satisfaction is the extent to which the patients feel that their needs and expectations are being met by the service provider. The survey of patient satisfaction with health care services is a growing concept in Nigeria, where study on this subject is just beginning to develop. Objective: The aim of this study was to compare the patients’ satisfaction level with radiological services and to identify the factors that may account for the differences in their satisfaction between a public and a private health facility in Kano state Nigeria. Method: The study was a cross-sectional prospective survey that targeted patients who visited radiology departments. Data was collected using a 43 item self-completion questionnaire designed in line with the objectives of the study. The data were categorized into groups and analysed using a statistical package for social sciences version 20.0, where descriptive statistics such as the percentages and frequencies were generated and tabulated. A chi-square test was used to test for the differences in the patients’ satisfactory level at (p<0.05). Results: The results showed that 60.7% (n=85) were female while 39.3% (n=55) were male, 52.2% (n=47) of the respondents from the public hospital were dissatisfied, while 47.8% (n=43) were satisfied. At the private hospital, only 20% (n=10) were dissatisfied, while 80% (n=40) were satisfied with the radiological services received. The type of health facility and patients’ satisfaction was found to be statistically significant at (p<0.05). Conclusion: The patients in the private health facility of the study were more satisfied than those at the public health facility because of prompt attention given to them immediately after arrival, immediate collection of their radiological reports, and high ergonometric environment provided by the hospital staff. - Uvod: Zadovoljstvo pacijenta jest predodžba pacijenta o stupnju u kojem određeni pružatelj zdravstvene usluge zadovoljava njegove zahtjeve i očekivanja. Ispitivanje zadovoljstva pacijenata zdravstvenim uslugama sve više dobiva na važnosti u Nigeriji, gdje se ta tema tek počinje proučavati. Cilj: Cilj je ovog istraživanja bio usporediti zadovoljstvo pacijenata radiološkim uslugama te izdvojiti čimbenike koji mogu objasniti razlike između zadovoljstva pacijenata javnim i privatnim zdravstvenim ustanovama u saveznoj državi Kano u Nigeriji. Postupak: Ovo je prospektivno presječno istraživanje proučilo odgovore pacijenata koji su posjetili odjele za radiologiju. Podaci su prikupljeni s pomoću upitnika s 43 pitanja oblikovanog u skladu s ciljevima istraživanja. Podaci su grupirani i analizirani primjenom statističkog programa za društvene znanosti verzije 20.0 kojim se opisne statistike poput postotaka i frekvencija generiraju i tabuliraju. Hi-kvadrat test primijenjen je kako bi se ispitale razlike u razini zadovoljstva pacijenata (p <0,05). Rezultati: Rezultati su pokazali da je 60,7 % (n = 85) ispitanika bilo ženskog spola, a 39,3 % muškog. Nezadovoljno je bilo 52,2 % (n = 47) pacijenata javne bolnice, dok je 47,8 % (n = 43) bilo zadovoljno. U privatnoj je bolnici samo 20 % (n = 10) ispitanika bilo nezadovoljno, dok je 80 % (n = 40) bilo zadovoljno radiološkim uslugama. Ustanovljeno je kako su vrsta zdravstvene ustanove i zadovoljstvo pacijenata statistički značajni (p <0,05). Zaključak: Pacijenti privatne zdravstvene ustanove bili su zadovoljniji od onih u javnoj zdravstvenoj ustanovi zbog brzine kojom im je pružena pažnja nakon dolaska, brzine kojom su im izdani radiološki nalazi te visokog stupnja ergonometrijskog okruženja koje im je osiguralo bolničko osoblje.

KUMPOVIĆ, Danijela
Što je nedostatna zdravstvena njega? [Elektronička građa] = What is missed nursing care? / Danijela Kumpović, Slađana Režić.
Bibliografija: 34 jed. - Sažetak ; Abstract. - Uvod: Nedostatna zdravstvena njega podrazumijeva dio njege ili njegu u cijelosti koja nije izvršena ili je izostavljena. Najčešći je uzrok tomu nedostatak osoblja i/ili vremena. U literaturi se navodi nekoliko pojmova koji su vezani za nedostatnu njegu. Najčešće se upotrebljavaju pojmovi „missed care“, „implicit rationing care“, „unfinished care“. U Hrvatskoj se pojam nedostatne njege tek počinje istraživati i najčešće se upotrebljava pojam nedostatne njege. Metode: Pretraživanjem baze podataka PubMed istraženi su instrumenti kojima se može mjeriti nedostatna njega, a koji su aktualni posljednjih 10 godina. Rezultati: Najčešći instrumenti korišteni u procjeni nedostatne zdravstvene njege su: Misscare survey, BERNCA, PIRNCA i TASK UNDONE. Svaki od instrumenata validiran je i preveden na nekoliko jezika. Navedeni instrumenti upotrebljavaju se u akutnim bolničkim ustanovama, dok je BERNCA modificiran instrument za mjerenje nedostatne njege koja se provodi u kući. Zaključak: Nedostatna zdravstvena njega pojam je koji u posljednje vrijeme u velikoj mjeri zaokuplja istraživače. Razvijeno je nekoliko instrumenata koji istražuju taj fenomen. Nedostatna zdravstvena njega utječe na kvalitetu skrbi koju zdravstveni djelatnici pružaju, kao i na njene ishode. Potrebno je provoditi daljnja istraživanja te bi se na temelju rezultata moglo kreirati povoljno radno okruženje i sigurna skrb za pacijente. - Introduction: Missed care is a part of care or the entirety of care that has not been performed or was left out. The most common cause of missed care is understaffing and/or lack of time. In literature is cited several terms associated with missed care. The most commonly used terms are „missed care“, „implicit rationing care“ and „unfinished care“. In Croatia the research on the concept of missed care has only just started. Methods: PubMed database was searched for data on available instruments used to measure missed care in the last 10 years. Results: The most common instruments used for the assessment of missed care are: Misscare survey, BERNCA, PIRNCA and TASK UNDONE. The said instruments have been validated and translated into several languages. These instruments are used in acute hospitals, while BERNCA was also modified for the measurement of missed care in home care. Conclusion: Lately the concept of missed care has been in the stronger focus of researchers. Several instruments were developed for the research of this phenomenon. Missed care affects the quality of provided care, as well as patient care outcomes. Further research needs to be done to improve working conditions and ensure safe patient care.

Zastupljenost sindroma izgaranja kod medicinskih sestara i tehničara na primarnoj i sekundarnoj razini zdravstvene zaštite [Elektronička građa] = Representation of burnout syndrome in nurses and technicians at primary and secondary levels of health care / Silvija Matuzić, Radoslav Kosić. - Graf. prikazi.
Bibliografija: 16 jed. - Sažetak ; Abstract. - Uvod: Sestrinska profesija predstavlja fizički, psihički, emocionalno i duhovno iscrpljujući te zahtjevan posao. Potreba pružanja usluga u zdravstvenoj skrbi u stalnom je porastu, uključujući sve zahtjevnija očekivanja od medicinskih sestara. Prema rezultatima istraživanja Svjetske zdravstvene organizacije o najstresnijim zanimanjima, sestrinski posao zauzima visoko četvrto mjesto. Cilj istraživanja: Cilj je istraživanja utvrditi subjektivne i objektivne dimenzije koje utječu na sindrom izgaranja medicinskih sestara i tehničara na primarnoj i sekundarnoj razini zdravstvene zaštite na području grada Karlovca. Ispitanici i metode: Istraživanje je provedeno u Domu zdravlja Karlovac i Općoj bolnici Karlovac. U istraživanje su uključene medicinske sestre i medicinski tehničari. Anonimni upitnik ispunilo je 65 ispitanika, od čega 30 ispitanika zaposlenih u Domu zdravlja Karlovac i 35 ispitanika zaposlenih u Općoj bolnici Karlovac. U istraživanju je korišten Upitnik za određivanje sindroma izgaranja na poslu. Rezultati: Rezultati istraživanja pokazuju da ne postoji statistički značajna razlika u zastupljenosti sindroma izgaranja s obzirom na primarnu i sekundarnu razinu zdravstvene zaštite, prema dobi i spolu, razini obrazovanja te rukovodećem radnom mjestu. Nadalje, rezultati pokazuju da je kod ispitanika koji imaju više godina radnog staža niža zastupljenost sindroma izgaranja, dok su stariji ispitanici više mrzovoljni, brže postanu razdražljivi i očekuju više od ljudi koji ih okružuju. Ispitanici višeg stupnja obrazovanja u većoj mjeri osjećaju da rade sve više, a manje su učinkoviti. Rezultati ukazuju na to da je 84,6 % ispitanika ovog istraživanja zahvaćeno sindromom izgaranja. Zaključak: Kod zaposlenika koji imaju više godina radnog staža verificiran je manji stupanj sindroma izgaranja. Moguće je da je to povezano s većim stupnjem zadovoljstva (veći stupanj spremnosti za napredovanjem i trajnom edukacijom). - Introduction: The nursing profession represents a physically, mentally, emotionally, spiritually exhausting, and demanding job. The need to provide health care services is constantly growing, including increasingly demanding expectations of nurses. According to the results of the World Health Organization’s research on the most stressful occupations, nursing takes a high fourth place. Aim: This paper aims to determine the subjective and objective dimensions that affect the burnout syndrome of nurses and technicians at the primary and secondary level of health care in Karlovac. Subjects and Methods: The study was conducted at the Health Center Karlovac and General Hospital Karlovac. Nurses and technicians were included in the research. An anonymous questionnaire was completed by 65 respondents, of whom 30 were employees of the Health Center Karlovac and 35 were employed at the General Hospital Karlovac. The survey used a Questionnaire to determine burnout syndrome at work. Results: The results show that there is no statistically significant difference in the incidence of burnout syndrome concerning primary and secondary health care levels, considering age and gender, education level, and managerial workplace. Furthermore, the results show that respondents who have more years of work experience show a lower prevalence of burnout syndrome, whereas older respondents are more cranky, quick-tempered, and expect more from the people around them. Respondents with higher education feel that they are doing more, but less effective. The results indicate that 84.6 % of the respondents in this study are affected by burnout syndrome. Conclusion: Employees with more years of service experience have a lower level of burnout syndrome verified, and that may also be associated with a higher degree of satisfaction (greater degree of readiness for advancement and continuing education), which is the basis for determining the quality of the work environment.

Zaštita osobnih podataka [Elektronička građa] / Jasenka Surla, Ivan Markotić, Olja Vori.
Bibliografske bilješke na kraju teksta. - Sažetak ; Abstract. - Opća uredba o zaštiti podataka 2016/679 postavila je imperativ na zaštitu osobnih podataka u pravnim sustavima država članica Europske unije, propisujući načela kojih su se voditelji i izvršitelji obrade dužni pridržavati u obavljanju socijalnih i gospodarskih djelatnosti. Gospodarska i društvena integracija utjecala je na povećanje opsega razmjene osobnih podataka između država članica i trećih zemalja, u javnom i privatnom sektoru. U takvim okolnostima potreban je novi i jači pravni okvir koji propisuje jasna prava i obveze sudionika društvenih odnosa. Pritom je važno omogućiti daljnje ostvarivanje potreba modernog društva pod uvjetom očuvanja temeljnih ljudskih vrednota i zaštite prava osobnosti svakog pojedinca, bez obzira na nacionalnost i boravište. Neovisno o pravnoj osnovi obrade osobnih podataka, ispitanici uvijek zadržavaju pravo na informiranost, pristup svojim podacima, brisanje, mijenjanje i prijenos osobnih podataka te ograničenje svrhe obrade. Međutim, pravo na brisanje osobnih podataka nije apsolutno pravo, već ga je potrebno staviti u ravnotežu sa zakonskim obvezama voditelja obrade na čuvanje određenih vrsta podataka. - The General Data Protection Regulation 2016/679 set out the imperative to protect personal data in the legal systems of the European Union Member States, stipulating the principles which the data processing directors and administrators are obliged to adhere to in carrying out their social and economic activities. Economic and social integration has led to an increase in the volume of exchange of personal data between the Member States and third countries in the public and private sectors. In these circumstances, a new and stronger legal framework prescribing the clear rights and obligations of participants in social relations is needed. At the same time, it is important to enable further fulfillment of the needs of the modern society, while preserving basic human values and protecting the rights of the individual’s personality, irrespective of their nationality and place of residence. Regardless of the legal basis for personal data processing, respondents always retain the right to be informed, access to their data, to delete, modify and transfer personal data, and limit the purpose of the processing. However, the right to erase personal data is not an absolute right, but it must be balanced against the legal obligations of the processing manager to keep certain types of data.

Assessing young gymnasts’ dynamic posture [Elektronička građa] : a comparison of methods / Ivan Jurak, Dalibor Kiseljak, Ozren Rađenović. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - Functional Movement Screen is an established method of assessing dynamic posture of athletes. Validity and reliability of FMS as a screening tool is debated and one of the foremost criticism is directed at its subjectivity. To the authors’ knowledge, there is no previous research using Kinovea to precisely assess FMS scores. 10 young competitive gymnasts (4 female and 6 male) were included in this study. The participants were scored by an experienced FMS assessor on site as per standard FMS protocol. Afterwards, the same participants were scored again using Kinovea to achieve more objective measurements. Wilcoxon Signed Rank Test for FMS scores versus FMS-Kinovea scores identified FMS test no. 1 (Deep Squat) as significantly different. The median score of Deep Squat assessed on site was 2 (mean value: 2.1), while that same test, scored with Kinovea, had the median score of 1 (mean value: 1.2). Paired Pitman-Morgan test for equality of variances was used to test the dispersion of scores. None were shown to be statistically significant, however, overall FMS score was near significance threshold implying that there is a difference although our power of study was too low probably due to low sample size. We detected significant difference in the scores of Deep Squat test, which is not surprising since it is the most complicated test to asses due to a large number of variables the assessor must evaluate. - Funkcionalna procjena pokreta (engl. Functional Move-ment Screen – FMS) je često korištena metoda za procjenu dinamičke posture sportaša. Upitna je valjanost i pouzdanost FMS-a kao metode za trijažu sportaša sklonih ozljedama, a jedna od glavnih kritika povezana je s objektivnošću same procjene. Ne postoje prethodna istraživanja koja su upotrebljavala računalni program Kinovea za preciznu procjenu s pomoću metode FMS. U ovom istraživanju sudjelovalo je 10 selekcioniranih sportskih gimnastičara (četiri djevojčice i šest dječaka). S pomoću metode FMS vježbači su procijenjeni prema uobičajenom protokolu. Nakon standardne procjene, isti su sudionici ponovno procjenjivani s pomoću metode FMS, no preko računalnog programa za kinematičku analizu Kinovea. S pomoću Wilcoxonova testa rangova uspoređeni su rezultati dobiveni primjenom dviju metoda FMS-a, standardne i Kinovea. S obzirom na rezultate, kod metode FMS-Kinovea pronađena je znatna razlika u testu 1 – Duboki čučanj. Medijan testa Duboki čučanj procijenjen standardnom metodom iznosio je 2 (srednja vrijednost iznosila je 2,1). Isti test procijenjen metodom FMS-Kinovea, imao je medijan 1 (srednja vrijednost bila je 1,2). Pitman-Morganov test za homogenost varijance primijenjen je za ispitivanje disperzije rezultata. Test nije pokazao nijednu razliku u homogenosti varijanci, no u sumiranom rezultatu testova p-vrijednost bila je blizu statističke značajnosti, što implicira postojanje razlike koju studija nije mogla otkriti zbog slabe snage istraživanja uzrokovane malim uzorkom. Razlika u rezultatima testa Duboki čučanj pokazala se značajnom, što nije iznenađujuće, s obzirom na to da je procjena upravo tog testa najsloženija zbog velikog broja varijabli u dinamičkoj posturi koje procjenjivač mora uzeti u obzir.

Availability and clinical use of different in-shoe devices for partial weight bearing [Elektronička građa] : a systematic review / Petra Josipović. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - Introduction: Physiotherapists use different methods such as tactile feedback, scales and biofeedback to teach patients applying the partial weight bearing instructions. Biofeedback systems are more effective and objective method than usage of conventional bathroom scales in training patients to comply with weight-bearing limitations. Aim: The current review will focus on the availability and clinical use of biofeedback in-shoe device in patients with prescribed PWB. Methods: A literature search was performed using the following keywords: partial weight bearing, biofeedback in-shoe device and surgery. Five databases were searched appropriate for screening (PubMed, PEDro, Google Scholar, Clinicaltrials.gov and ScienceDirect). Results: Filtration strategy was used in a literature search. 15 sources were selected for final analysis. Qualitative analytical approach was used in data processing. Conclusion: Biofeedback systems have been more effective than conventional bathroom scales in training patients to comply with weight-bearing limitations. With additional randomised controlled trials, biofeedback devices may very well become a part of the mainstay of clinical practice in orthopaedic partial weight-bearing patients. - Uvod: Fizioterapeuti primjenjuju različite metode kao što su taktilna sprega, uporaba vage i uporaba uređaja za biofeedback u učenju pacijenata pravilnom doziranom opterećenju nakon operacijskih zahvata. Učenje ortopedskih pacijenata pravilnom doziranom opterećenju ekstremiteta s pomoću uređaja za biofeedback objektivnija je i učinkovitija metoda fizioterapijskog tretmana od metode primjene vage. Cilj: Sistematični pregledni članak fokusirat će se na problematiku dostupnosti i kliničke uporabe uređaja za biofeedback kod pacijenata kojima su fizioterapeut i liječnik propisali dozirano opterećenje. Metode: U pretrazi su upotrijebljene sljedeće ključne riječi: dozirano opterećenje, uređaj za povratnu spregu u cipeli, uređaji za biofeedback, operacija. Pretraga je provedena u pet bibliografskih baza podataka (PubMed, PEDro, Google Scholar, ClinicalTrials.gov i ScienceDirect). Rezultati: U pretrazi literature primijenjena je strategija filtracije izvora prema određenim parametrima. U obradi podataka primijenjen je kvalitativni analitični pristup. Za konačnu analizu odabrano je 15 prikladnih izvora. Zaključak: Sustavi za biofeedback učinkovitiji su od konvencionalnih vaga u podučavanju pacijenata pravilnom doziranom opterećenju oštećenih ekstremiteta. Daljnjim znanstvenim, randomiziranim i kliničkim istraživanjima, sustavi za biofeedback mogu postati važan dio kliničke prakse u tretmanu ortopedskih pacijenata s propisanim doziranim opterećenjem.

Dabigatran use associated with hemopericardium and hemothorax [Elektronička građa] / Josip Katić, Marko Skelin, Ana Katić, Karla Katić, Ružica Avelini Perković, Dario Rahelić, Jure Mirat.
Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - Concurrent spontaneous hemopericardium and hemothorax due to anticoagulant use are extremely rare in clinical practice. Dabigatran is an oral direct thrombin inhibitor approved to prevent stroke or thromboembolic episodes in patients with nonvalvular atrial fibrillation. We report the case of a 73-year-old man who received dabigatran therapy (150 mg twice a day) for 3 months and developed massive spontaneous hemothorax and hemopericardium associated with fever. Emergency chest computed tomography scan established higher-density pericardial effusion (22HU) and left pleural effusion of heterogeneous density (5–15 HU) which could be hemorrhagic content while the heart ultrasound finding confirmed pericardial effusion 7–9 mm thick, without affecting hemodynamics. Almost 1100 mL of blood was drained by ultrasoundguided thoracentesis. After excluding other possible causes, diagnostic withdrawal was performed for dabigatran and no further pleural or pericardium effusion developed after dabigatran was discontinued. Therefore, practitioners could be aware of hemothorax as well as hemopericardium as a potential complication of dabigatran therapy. - Istodobno spontani hemoperikard i hemotoraks tijekom primjene oralnih antikoagulanata izuzetno je rijetka pojava u kliničkoj praksi. Dabigatran je oralni izravni inhibitor trombina odobren za prevenciju moždanog udara ili tromboembolijskih događaja u bolesnika s nevalvularnom fibrilacijom atrija. Prikazan je slučaj 73-godišnjaka na terapiji dabigatranom (150 mg dva puta dnevno) od 3 mjeseca sa razvojem masivnog spontanog hemotoraksa i hemoperikarda praćeno vrućicom. Višeslojna kompjutorizirana tomografija (MSCT) toraksa je pokazala perikardijalni izljev veće gustoće (22HU) kao lijevi pleuralni izljev heterogene gustoće (5–15 HU), opisano kao mogući hemoragični sadržaj, dok je nalaz ultrazvuka srca verificirao perikardijalni izljev od 7–9 mm, bez utjecaja na hemodinamiku. Torakocentezom se evakuira gotovo 1100 ml krvi. Urađenom kliničkom obradom isključeni su drugi uzroci te se izostavljanjem dabigatrana iz terapije prekinulo daljnje nakupljanje krvi u perikard ili pleuralni prostor. Tijekom primjene dabigatrana moguć je potencijalni nastanak hemoragičnih komplikacija na koje svakako treba pomišljati.

Marihuana - zlouporaba i medicinska uporaba [Elektronička građa] / Marija Markus Klarić, Dubravko Klarić, Ognjen Brborović, Krunoslav Capak. - Graf. prikazi.
Bibliografske bilješke uz tekst ; bibliografija: str. 149-150. - Sažetak ; Summary. - Indijska konoplja (lat. Cannabis sativa L., podvrsta indijska) prati čovjeka od pradavnih vremena pa sve do danas. Prepoznati učinci indijske konoplje kao psihoaktivnog sredstva (glavni sastojak THC delta-9-tetrahidrokanabinol) doveli su do različitih oblika uporabe, ali i kao lijeka u medicinske svrhe. Tehnološki napredak, brojna istraživanja, dovela su do otkrića velikog broja drugih sastojaka (CBD kanabidiol – kanabinoidi) koje sadržava indijska konoplja, a nisu psihoaktivni, međutim našli su svoju primjenu u medicinskoj terapiji. Samom uporabom nužno se pojavila i zlouporaba. Marihuana je danas, iako samo kao jedan od produkata, postala u svakodnevnoj komunikaciji sinonim za indijsku konoplju. Na nelegalnim je tržištima najraširenija droga, kako u ponudi tako i potražnji (produkti hašiš, ulje hašiša, razne mješavine i oblici produkata indijske konoplje nisu toliko rasprostranjeni kao marihuana). Proizvodnju, prenošenje – krijumčarenje, preprodaju i konzumaciju trebalo je staviti pod državni nadzor, odnosno u zakonske okvire, što je i učinjeno, ali uz stalne promjene. To se nije moglo i ne može se regulirati samo u nacionalnim okvirima, već prema konvencijama na širokoj međunarodnoj sceni, uz učešće međunarodnih organizacija, poglavito UN-a. Ipak usklađenost nacionalnih zakonskih okvira s međunarodnima ostavlja prostor za današnje trendove u smislu dekriminalizacije, depenalizacije i legalizacije, što je isto tako dio kulturoloških, bihevioralnih, socioloških, ali i političkih pristupa prema određivanju uporabe i zlouporabe. Granicu između nelegalne odnosno nezakonite primjene ponekad će biti teško odrediti, ali svakako u tom smislu potreban je znanstveni i empirijski multidisciplinarni pristup, razumijevanje, ali i donošenje odgovarajućih odluka. - This paper elaborates the importance of the use and abuse of Indian hemp (Cannabis sativa L., subspecies Indian). Its recognized effects as a psychoactive agent (the major constituent is THC delta-9-tetrahydrocannabinol) have led to different forms of use, which also include its use as a medicine for medical purposes. Technological advances and related research have led to the discovery of a large number of other ingredients (CBD cannabidiol – cannabinoids) in Indian hemp which are not psychoactive, but have nevertheless found application in medical treatment. Marijuana today, though only as one product, has in daily communication become synonymous with Indian hemp. It is the most widely offered and sought after drug in illegal markets (hashish products, hashish oil, various blends and forms of Indian hemp products are not as widespread as marijuana). The boundary of use illegal will sometimes be difficult to determine, but certainly in this respect, a scientific and empirical multidisciplinary approach, understanding and decision-making are needed.

Mixed oxides as successful sorption materials for some active pharmaceutical ingredients [Elektronička građa] / Eva Vrbková, Eliška Vyskočilová, Aneta Semrádová, Lada Sekerová, L. Červený. - Graf. prikazi.
Bibliografija: 24 jed. - Summary. - Mixed oxides based on Mg-Al, Mg-Fe, Zn-Al, and Ni-Mg-Al were prepared, characterized and used as sorption materials for different types of active pharmaceutical ingredients (APIs)– nicotinic acid, salicylic acid, ibuprofen, paracetamol and ascorbic acid. Immobilization of APIs on solid supports was confirmed using X-Ray diffraction and infrared spectroscopy. Overall, the best sorption material for mentioned substances showed to be mixed Mg-Al oxides (>80 % of immobilized substance after 4 h except ascorbic acid). On the other hand, Mg-Fe and Mg-Ni-Al materials did not possess high sorption capacity (max. 59 % after 4 h). From studied substances, the immobilization amount was the lowest in the case of ascorbic acid (max. 44 % immobilized after 4 h), the highest amount was immobilized in the case of salicylic and nicotinic acids (>95 %, 4 h). The discussion regarding the structure of substances and properties of sorption materials is also offered.

Religija i liječenje ovisnosti [Elektronička građa] : molitva, rad i razgovor kao vid rehabilitacije na primjeru zajednice Cenacolo / Filip Trbojević. - Ilustr.
Bibliografske bilješke uz tekst. - Sažetak ; Summary. - Odnos religije i zdravlja posljednjih je godina predmet zanimanja različitih znanstvenih disciplina. Primjećujući da u kontekstu suvremenih sociokulturnih procesa fenomen religije sve češće izlazi iz strogih institucionalnih okvira te, kao takav, prodire u različite svjetovne probleme i izazove, u ovom smo radu na primjeru Zajednice Cenacolo, zajednice za pomoć mladima koja svoj program temelji na vjeri, prikazali problem liječenja ovisnosti u religijskom kontekstu te produbili spoznaje o oblicima pomoći ovisnicima koji izlaze iz strogih okvira biomedicine. Koristeći se metodom etnografskog istraživanja te tehnikom polustrukturiranog problemski orijentiranog intervjua i sudioničkog promatranja, utvrdili smo sličnosti rehabilitacijskog programa Zajednice Cenacolo s programima konvencionalnih terapijskih zajednica za liječenje ovisnosti, artikulirali religijski aspekt liječenja ovisnosti te utvrdili važnost njegova međuodnosa s radom i grupnim razgovorima – praksama na kojima Zajednica temelji svoj rehabilitacijski program. - In recent years the relationship between religion and health has been a subject of interest to various scientific disciplines. Noticing that in the context of contemporary sociocultural processes the phenomenon of religion more and more often goes beyond the rigid institutional framework, and, as such, penetrates into various secular issues and challenges, in this paper we have used the example of Cenacolo Community – a community which helps young people and bases its program on faith – to present the issue of addiction treatment in a religious context and deepen the knowledge about forms of helping addicts that go beyond the rigid framework of biomedicine. Using the method of ethnographic research as well as a semi-structured problem-oriented interview and participant observation, we ascertained the similarities between the rehabilitation programs of Cenacolo Community and the programs of conventional therapeutic communities for addiction treatment, articulated the religious aspect of addiction treatment and determined the importance of the relationship between the latter and work and group conversations – the practices on which the Community bases its rehabilitation program.

Sestrinska skrb za bolesnika liječenog VAC terapijom [Elektronička građa] / Klaudia Knezić, Jasmina Kruško, Sanela Takus, Mateja Krznar. - Graf. prikaz.
Bibliografske bilješke na kraju teksta. - Sažetak ; Summary. - Terapija negativnim tlakom (Vacuum Assisted Closure) je metoda liječenja rana koja se praktično primjenjuje u klinikama diljem svijeta, a počeci joj se naziru još u 1995. godini. VAC sustav osobito je učinkovit u liječenju traumatskih i kroničnih rana. Uspjeh liječenja VAC terapijom ovisi o nekoliko čimbenika, od kojih su najznačajniji dobra kirurška tehnika, pravilna procjena stanja bolesnika, te planiranje i provođenje postupka s pozitivnom evaluacijom na kraju liječenja. Postupci medicinske sestre kod postavljanja VAC aparata usmjereni su na psihofizičko stanje pacijenta, procjenu kože prije i nakon primjene VAC terapije, procjenu okolnog tkiva, procjenu položaja bolesnika u krevetu, procjenu i prilagodbu mikroklimatskih uvjeta te procjenu prisutnosti rizika od krvarenja. Veoma je važna edukacija bolesnika. Cilj članka je opisati postupak liječenja kronične rane VAC terapijom te pobliže objasniti zadaće medicinske sestre tijekom VAC terapije. Medicinska sestra mora posjedovati specifična znanja radi provođenja postupka, mora biti educirana u pružanju zdravstvene njege bolesniku s kroničnom ranom te podrška i oslonac bolesniku. VAC metoda je siguran i uspješan način liječenja, a s obzirom na to da je ekonomski povoljna za zdravstveni sustav i bolesnike, sve je češće metoda izbora u liječenju bolesnika s kroničnim ranama. - Negative Pressure Therapy – Vacuum Assisted Closure – is a wound treatment method used in clinical practice throughout the world. Its beginnings date back to the year 1995. The VAC system is particularly effective in treatment of traumatic and chronic wounds. The success of VAC therapy treatment depends on several factors, the most important of which are a good surgical technique, proper assessment of the patient’s condition, and planning and conducting procedure, which are positively evaluated at the end of the treatment. Nurse’s interventions are focused on assessment of the patient’s psychophysical condition, skin condition assessment before and after the treatment, assessment of the skin surrounding the wound, proper body position during the procedure, assessment and adjustment of microclimate conditions, as well as bleeding risk estimate. Education of the patient must be accentuated as the most important intervention. The objective of this article is to describe the procedure of chronic wound treatment using VAC system and to explain the tasks of nurses in the course of VAC therapy. Nurses need to possess specific knowledge for the purpose of conducting the procedure, they need to be educated in providing the patient’s health care, and they need to provide support both to the patient and their family. VAC method is a safe and successful treatment method and since it is economically affordable both for the healthcare system and the patients, it is increasingly frequently selected for the treatment of patients with chronic wounds.

Sustavni pregled utjecaja plesa tanga na hod i ravnotežu osoba s Parkinsonovom bolešću [Elektronička građa] / Kristina Delaš, Lana Erjavec, Gordana Grozdek Čovčić, Mirjana Telebuh, Ivan Jurak. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Sažetak ; Summary. - Uvod: Neka istraživanja ukazuju na to da ples utječe na poboljšanje hoda i balansa osoba s Parkinsonovom bolešću te kako utjecaj glazbe i ritma facilitira kretanje i brzinu kod ljudi s Parkinsonovom bolešću. Blagotvorni učinci ritma i glazbe proizlaze iz aktiviranja neuralnih struktura uključenih u kretanje i određivanje vremena. Metode: Rad je sustavni pregled literature pretraživanjem relevantnih članaka baza podataka PubMed, PE-Dro, LILACS i Cochrane library od 2007. do 2020. godine. Kriteriji su istraživanja koja se bave utjecajem tanga na hod i balans kod osoba s Parkinsonovom bolešću primjenom standardiziranih testova Berg balans skale (BBS), testa Time up and go (TUG) i Unified Parkinsonʼs Disease Rating Scale III (UPDRS-III). Iz sustavnog pregleda literature od ukupno 65 pronađenih radova uključeno je šest članaka koji zadovoljavaju zadane kriterije. Rezultati: Uspoređujući trajanje intervencija, istraživanja su se provodila uglavnom kratkoročno i intenzivno te dugoročno i umjereno. Prakticiranjem tanga u kratkoročnom ili dugoročnom razdoblju dolazi ne samo do poboljšanja balansa nego i povećanja tjelesnog fitnesa. Rezultati kratkoročnih istraživanja pokazala su statistički značajne razlike kod testova UPDRS-III i BBS u korist skupina koje su kao intervenciju imale tango, dok se kod dugoročnih istraživanja uočavaju poboljšanja u balansu i hodu koja se nisu pokazala kod kratkoročne i intenzivne intervencije tangom. Zaključak: Dokazi o poboljšanju funkcionalne mobilnosti i balansa potiču na proširivanje spektra rehabilitacije kod osoba s Parkinsonovom bolešću jer je tango ples koji svojim ritmom, glazbom i širinom koraka itekako pronalazi mjesto u rehabilitaciji osoba s Parkinsonovom bolešću. - Introduction: Some research suggest that dancing improves gait and balance in people with Parkinson’s disease. Also suggest influence of music and rhythm on speed and facilitation of movement in people with Parkinson’s disease. The beneficial effects of rhythm and music result from the activation of neural structures involved in movement and timing. Methods: This paper is a systematic review of the literature searched through relevant database Pubmed, PEDro, LILACS and Cochrane library published in the period from 2007 to 2020. Our criteria for including papers in review were research on tango impact on gait and balance in people with Parkinson’s disease, use of standard tests as Berg balance scale (BBS), Time up and go test (TUG) and Unified Parkinsonʼs Disease Rating Scale III (UPDRS-III). After preformed review only 6 researches were selected in further analysis. Results: Comparing the duration of interventions, the researches were conducted mainly in the short term and intensive and in the long term and moderate. Tango dancing in the short term or long term leads to an improvement not only in balance but also in improvements in body fitness. The results from short term researches showed statistically significant differences in UPDRS III and BBS in tango dancing groups. While in long-term studies we observed improvements in balance and gait which was not shown in short term and intensive tango intervention. Conclusion: Evidence of improved functional mobility and balance encourages the expansion of the spectrum of rehabilitation in people with Parkinson’s disease. Because tango is a dance that, with its rhythm, music, and step width, finds a place in the rehabilitation of people with Parkinson’s disease.

A case of IgE myeloma transformed into IgE-producing plasma cell leukaemia [Elektronička građa] / Nicolas Galakhoff, Cyril Leven, Jean-Richard Eveillard, Adrian Tempescul, Hélène Kerspern, Cécile Aubron, Caroline Buors, Éric Lippert, Jean-Luc Carré, Maël Padelli. - Graf. prikazi.
Bibliografija: 33 jed. - Summary. - This is a case report of a challenging diagnosis of IgE monoclonal gammopathy of undetermined significance, which transformed into myeloma, then transformed into IgE-producing plasma cell leukaemia in a 71-year-old male who was followed in Brest, France, from 2015 to 2019. The IgEproducing variant is the rarest sub-type of multiple myeloma, and plasma cell leukaemia is considered to be the rarest and the most aggressive of human monoclonal gammopathies. In November 2015, hypogammaglobulinemia was detected during a systematic check-up. A kappa light chain monoclonal gammopathy was first diagnosed due to an increase of the free kappa/lambda light chains ratio. No monoclonal immunoglobulin was detected by either serum protein electrophoresis (Capillarys 2, Sebia, Issy-les-Moulineaux, France) or immunofixation (Hydrasys 2, Sebia, Issy-les-Moulineaux, France). In June 2018, a blood smear led to the diagnosis of plasma cell leukaemia. A monoclonal peak was detected and identified as IgE-kappa. Analysis of an archival sample taken three years earlier, revealed the presence of a monoclonal IgE, which had been missed at diagnosis. Chemotherapy with bortezomib and dexamethasone was introduced. The patient survived 10 months after the diagnosis of leukaemia. This case shows that an abnormal free light chain ratio should be considered as a possible marker of IgE monoclonal gammopathy even in the absence of a solitary light chain revealed by immunofixation. In addition, the use of an undiluted serum may increase the sensitivity of the immunofixation forthe detection of IgE monoclonal gammopathies compared to the 1:3 dilution recommended by the manufacturer.

Bibliografija: 20 jed. - Summary. - Introduction: Severe hyperkalaemia is a serious medical condition requiring immediate medical attention. Before medical treatment is started, pseudohyperkalaemia has to be ruled out. Case description: A 10-month old infant presented to the emergency department with fever and coughing since 1 week. Routine venous blood testing revealed a severe hyperkalaemia of 6.9 mmol/L without any indication of haemolysis. Reanalysis of the plasma sample confirmed the hyperkalaemia (7.1 mmol/L). Based on these results, the clinical pathologist suggested to perform a venous blood gas analysis and electrocardiogram (ECG) which revealed a normal potassium of 3.7 mmol/L and normal ECG, ruling out a potentially life-treating hyperkalaemia. The child was diagnosed with pneumonia. The paediatrician had difficulty to perform the first venous blood collection due to excessive movement of the infant during venipuncture. The muscle contractions of the child in combination with venous stasis most probably led to a local increase of potassium in the sampled limbs. The second sample collected under optimal preanalytical circumstances had a normal potassium. Since muscle contraction typically does not cause severe hyperkalaemia, other causes of pseudohyperkalaemia were excluded. K3-EDTA contamination and familial hyperkalaemia were ruled out and the patient did not have extreme leucocytosis or thrombocytosis. By exclusion a diagnosis of pseudohyperkalaemia due to intense muscle movement and venous stasis was made. Conclusion: This case suggests that intense muscle contraction and venous stasis can cause severe pseudohyperkalemia without hemolysis. Once true hyperkalemia has been ruled out, a laboratory work-up can help identify the cause of pseudohyperkalaemia.

A method comparison study of a point-of-care blood gas analyser with a laboratory auto-analyser for the determination of potassium concentrations during hyperkalaemia in patients with kidney disease [Elektronička građa] / Mogamat-Yazied Chothia, Patricia Kassum, Annalise Zemlin. - Graf. prikazi.
Bibliografija: 28 jed. - Summary. - Introduction: Hyperkalaemia is a common electrolyte disorder that may cause life-threatening cardiac arrythmias. We aimed to determine theagreement of potassium concentrations between GEM premier 3500 point-of-care blood gas analyser (POC-BGA) and Roche Cobas 6000 c501 autoanalyserin patients with hyperkalaemia.Methods: A prospective, cross-sectional study of all consecutive adult patients referred to the Renal Unit with a serum potassium concentration ≥5.5 mmol/L was performed. A total of 59 paired venous blood samples were included in the final statistical analysis. Passing-Bablok regression andBland Altman analysis were used to compare the two methods.Results: The median laboratory auto-analyser potassium concentration was 6.1 (5.9-7.1) mmol/L as compared to the POC-BGA potassium concentrationof 5.7 (5.5-6.8) mmol/L with a mean difference of - 0.43 mmol/L and 95% upper and lower limits of agreement of 0.35 mmol/L and - 1.21mmol/L, respectively. Regression analysis revealed proportional systematic error. Test for linearity did not indicate significant deviation (P = 0.297).Conclusion: Although regression analysis indicated proportional systematic error, on Bland Altman analysis, the mean difference appeared to remainrelatively constant across the potassium range that was evaluated. Therefore, in patients presenting to the emergency department with aclinical suspicion of hyperkalaemia, POC-BGA potassium concentrations may be considered a surrogate for laboratory auto-analyser measurementsonce clinicians have been cautioned about this difference.

A rare case of tuberculosis-induced hypercalcemia [Elektronička građa] / Loris Wauthier, Xavier Theunssens, Patrick Durez, Catherine Fillée, Diane Maisin, Damien Gruson. - Graf. prikazi.
Bibliografija: 15 jed. - Summary. - Laboratory investigations of hypercalcemia involve testing of various biochemical parameters such as parathyroid hormone (PTH), 25-(OH) Vitamin D (25-(OH) VitD), 1,25-(OH)2 Vitamin D3 (calcitriol) and PTH related peptide (PTHrp). We herein present an atypical case of severe hypercalcemia in a patient with rheumatoid arthritis who has been treated for years by various biological disease-modifying antirheumatic drugs (DMARDs) and suddenly presented with general state alteration, oedema and ulceration of her right ankle. We illustrate how tuberculosis (TB) can cause high calcitriol concentration and subsequently lead to potentially severe hypercalcemia. Moreover, we highlight the importance of TB testing and follow-up in patients treated with biological DMARDs.

Association of latent tuberculosis infection in health care workers with allergy and allergic sensitization to common aeroallergens [Elektronička građa] / Ivana Banić, Sandra Bulat Lokas, Davor Plavec, Rajka Lulić Jurjević, Boro Nogalo, Mirjana Turkalj. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - Health care workers (HCW) are at increased risk of a latent tuberculosis infection (LTBI) due to occupational exposure to Mycobacterium tuberculosis. In order to investigate the mutual influence of a TH1 type immune response caused by LTBI and T helper 2 (TH2) type immune response caused by allergy, we conducted a study examining the prevalence of common inhaled allergen sensitization in the HCW population with different levels of exposure to tuberculosis (high and low). HCW with possible exposure to tuberculosis (TB) were tested with QuantiFERON-TB Gold (QFT-G) and tuberculin skin test (TST), while skin prick test (SPT) was performed for inhaled allergens. The antigen (Ag) response at QFT-G was inversely correlated with participants` allergy anamnesis (p= 0.039). Sensitization to inhaled allergens (positive SPT and number of positive allergens at SPT) was more prominent in the low exposure group (p= 0.006 and p= 0.0065, respectively). Ag response at QFT-G test was significantly higher in participants with no medical history of allergy (p= 0.048). Our results demonstrate that exposure to TB and LTBI are associated with inhaled allergen sensitization in HCW, possibly inhibiting allergic sensitization by mediating the T-helper type 1 (Th1) immune response. - Zdravstveni radnici imaju povećan rizik od latentne tuberkulozne infekcije (LTBI) zbog profesionalne izloženosti Mycobacterium tuberculosis. Kako bismo istražili međusobni odnos imunološkog odgovora posredovanog stanicama Th1 uzorkovanog tuberkuloznom infekcijom i onog posredovanog limfocitima Th2 u alergijama, istražili smo prevalenciju senzibilizacije na uobičajene inhalacijske alergene u zdravstvenih radnika s različitim stupnjem rizika od izoloženosti tuberkulozi (visok i nizak stupanj). Izloženost tuberkulozi i LTBI u zdravstvenih radnika testirani su korištenjem QuantiFERON-TB Gold (QFT-G) i tuberkulinskog kožnog testa (TST), a senzibilizacija na inhalacijske alergene je utvrđena kožnim ubodnim testom. Antigenski (Ag) odgovor na QFT-G testu inverzno je korelirao s osobnom anamnezom alergija sudionika (p= 0.039). Senzibilizacija na inhalacijske alergene (pozitivan kožni ubodni test i broj pozitivnih alergena na kožnom ubodnom testu) bila je izraženija u skupini sudionika s niskim rizikom od izloženosti tuberkulozi (p= 0.006 and p= 0.0065, respektivno). Ag odgovor na QFT-G testu bio značajno viši u sudionika s negativnom osobnom anamnezom alergija (p= 0.048). Rezultati ove studije ukazuju na to kako su izloženost tuberkulozi i LTBI povezani sa senzibilizacijom na uobičajene inhalacijske alergene u zdravstvenih radnika, potencijalno inhibirajući alergijsku senzibilizaciju indukcijom imunološkom odgovora posredovanog stanicama Th1.

Characteristics of COVID-19 infection among nursing home residents [Elektronička građa] : a cross sectional study from Croatia / Maja Mizdrak, Ante Mayer, Ivan Jerković, Ivan Mizdrak, Tina Tičinović Kurir. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - Given high risk of infection-related mortality due to impaired immunity, elderly patients are at increased risk with COVID-19. In its diagnostic procedure clinical laboratory medicine has a pivotal role. The aim of this study was to investigate clinical and laboratory specificities in Croatian population of nursing home residents affected by coronavirus. One hundred and six residents of nursing homes that were hospitalized due to COVID-19 infection, were included in this retrospective study. Clinical and laboratory findings at three time points were extracted from medical records. There were 86 females and 20 males, with median of age 84 (min-max: 47–97) years. Patients were divided into three groups: Survivors (S), patients who are still alive (N=65), In-Hospital Non-Survivors (IHNS), patients who died from coronavirus during hospitalization (N=31) and Out-of-Hospital Non-Survivors (OHNS), patients who recovered from infection but died during the period of three months of the follow-up (N=10). We have established differences between these three groups in laboratory findings (p<0.05). At the admission, survivors had lower values of lactate dehydrogenase, aspartate transaminase, sedimentation ratio, ferritin and C-reactive protein, OHNS were in the middle, and IHNS had the highest values. Leukocytes and absolute lymphocyte count were greater in OHNS group, and same between survivors and IHNS. After 7 days, we noticed increase in leukocyte and neutrophils count among IHNS. Assessing of complete blood count, differential blood count, reactants of acute infection and combination of their ratios might predict worse outcome in nursing home residents due to coronavirus infection. - S obzirom na visok rizik od smrtnosti povezane s infekcijom zbog oslabljenog imuniteta, stariji pacijenti imaju povećan rizik od zaraze COVID-19. U dijagnostičkom postupku klinička laboratorijska medicina ima ključnu ulogu. Cilj ovog istraživanja bio je istražiti kliničke i laboratorijske specifičnosti u hrvatskoj populaciji štićenika domova za starije pogođenih koronavirusom. U ovu retrospektivnu studiju uključeno je 106 štićenika domova za starije koji su hospitalizirani zbog infekcije COVID-19. Klinički i laboratorijski nalazi u tri vremenska razdoblja izvučeni su iz medicinske evidencije. Istraživanje je uključilo 86 žena i 20 muškaraca, srednje dobi 84 (min-max: 47–97) godine. Pacijenti su podijeljeni u tri skupine: preživjeli (S), pacijenti koji su još uvijek živi (N = 65), (IHNS), pacijenti koji su umrli od koronavirusa tijekom hospitalizacije (N = 31) i (OHNS), pacijenti koji su se oporavili od infekcije, ali su umrli tijekom razdoblja od tri mjeseca praćenja (N = 10). Utvrdili smo značajne razlike između ove tri skupine u laboratorijskim nalazima (p <0,05). Istraživanje pokazuje da procjene kompletne krvne slike, diferencijalne krvne slike, reaktanata akutne infekcije i kombinacija njihovih omjera mogu ukazivati na lošiji ishod štićenika domova za starije zbog infekcije koronavirusom.

The effect of therapy of the lower urinary tract symptoms due to prostatic benign enlargement on erectile function [Elektronička građa] / Anja Štraus, Sandi Poteko, Andrej Starc. - Graf. prikaz.
Bibliografske bilješke na kraju teksta. - Summary ; Sažetak. - Background: Benign prostatic enlargement is the most common benign disease in men. The main cause for the emergence of benign prostatic enlargement is sexual hormone testosterone. Under the influence of enzyme 5-alpha reductase testosterone turns into active dihydrotestosterone, which is then combined with receptors and causes the growth of the prostate. Benign prostatic enlargement can cause the lower urinary tract symptoms. One of the treatment options of lower urinary tract symptoms due to benign prostatic enlargement is the treatment with medicaments – inhibitors 5-alpha reductase. Like any other medicament, this one can also have unpleasant side effects, between others reduced erectile function and reduced libido. Methods: We used the International Index of Erectile Function (IIEF-5), Quality of Erection Questionnaire (QEQ), and demographic data. Results: Men with benign prostatic enlargement have problems with keeping an erection even before starting the therapy with medicaments. After the therapy with inhibitors 5-alpha reductase the results of the research show that on the erectile function scale, there are no significant differences between the first and second measurement, but on the erectile dysfunction scale expected differences occur – the functionality decreases. We also noticed that the independent variables of age and employment status have influence on the result of medicament treatment in the way that older participants in the study have more issues with erectile function than younger ones. Secondly, the men in retirement have more problem than employed men. There were no noticeable connections between the level of completed education and the profession of the participants. Conclusions: The results of the research were expected, according to the previously consulted literature, where the side effects of treatment with medicaments inhibitors 5-alpha reductase were already mentioned. The effects that the treatment has on erectile functio. - Uvod: Dobroćudno povećanje prostate je najčešća dobroćudna bolest u muškaraca. Glavni uzročnik pojave dobroćudnog povećanja prostate je muški spolni hormon testosteron. Pod utjecajem enzima 5-alfa reduktaze testosteron se pretvara u aktivni dihidrotestosteron, koji se tada kombinira s receptorima i uzrokuje rast prostate. Dobroćudno povećanje prostate može uzrokovati simptome u donjem mokraćnom sustavu. Jedna od mogućnosti liječenja simptoma donjeg dijela mokraćnog sustava uslijed dobroćudnog povećanja prostate je liječenje lijekovima - inhibitorima 5-alfa reduktaze. Kao i bilo koji drugi lijek, i ovaj može imati neugodne nuspojave, između ostalih smanjenu erektilnu funkciju i smanjeni libido. Metode: Koristili smo međunarodni indeks erektilne funkcije (IIEF-5), upitnik o kvaliteti erekcije (QEQ) i demografske podatke. Rezultati: Muškarci s benignim povećanjem prostate imaju problema s održavanjem erekcije, čak i prije nego što započnu terapiju lijekovima. Nakon terapije inhibitorom 5-alfa reduktaze rezultati istraživanja pokazuju da na ljestvici erektilne funkcije nema značajnih razlika između prvog i drugog mjerenja, ali na ljestvici erektilne disfunkcije dolazi do očekivanih razlika - funkcionalnost opada. Također smo primijetili da nezavisne varijable dobi i zaposlenja imaju utjecaj na rezultat liječenja lijekovima na način da stariji sudionici u istraživanju imaju više problema s erektilnom funkcijom od mlađih muškaraca. Zatim, muškarci u mirovini imaju više problema nego muškarci koji su zaposleni. Nisu bile uočljive veze između završene razine obrazovanja i profesije sudionika. Zaključci: Rezultati istraživanja bili su očekivani, prema prethodno konzultiranoj literaturi, gdje su već spomenute nuspojave liječenja inhibitorima 5-alfa reduktaze. Učinak koji tretman ima na erektilnu funkciju je pogoršanje funkcije, zato je važno potražiti pomoć liječnika odmah nakon što se pojavi.

Factors associated with road traffic injuries and their severity [Elektronička građa] : a prospective cohort study / Jelena Kovačević, Maja Miškulin, Hrvoje Palenkić, Marina Samardžija, Milanka Mrčela, Branka Lončar, Slavko Čandrlić, Marinela Kristić, Oliver Pavlović, Ivan Miškulin. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - Road traffic injuries cause considerable losses to individuals, their families, and to nations as a whole. Factors related to road traffic injuries and to the severity of such injuries have not been fully elucidated or evaluated. The aim of this study was to explore factors related to road traffic injuries and their severity in cohort of 200 road traffic accident (RTA) survivors from Eastern Croatia. Sustaining injury was associated with rural residence (p=0.032), lower education level (p=0.001), unemployment (p=0.001), being single (p=0.014), under average self-assessed economic status (p=0.001), alcohol abstinence (p=0.018), use of medications (p=0.031), self-assessed life-threat (p<0.001), pain after the RTA (p<0.001), hospitalization after the RTA (p<0.001), hospitalization duration (p<0.001), surgery (p=0.048), rehabilitation following the RTA (p=0.001) and PTSD symptoms (p=0.001). Injury severity was associated with lower education level (p=0.013), unemployment (p=0.004), being single (p=0.017), under average self-assessed economic status (p<0.001), alcohol abstinence (p=0.042), use of medications (p=0.014), self-assessed life-threat (p<0.001), pain after the RTA (p<0.001), being a pedestrian or a cyclist (p=0.011), hospitalization after the RTA (p<0.001), hospitalization duration (p<0.001), surgery (p<0.001), rehabilitation following the RTA (p=0.001), depression (p<0.001) and PTSD symptoms (p<0.001). In order to more adequately prevent road traffic injuries knowledge about factors associated with such injuries and their severity should be base for the creation of specific prevention programs at regional and national level. - Ozljede u cestovnom prometu uzrokuju znatne gubitke pojedincima, njihovim obiteljima i cijeloj naciji. Čimbenici povezani s ozljedama u cestovnom prometu i težinom takvih ozljeda nisu u potpunosti razjašnjeni ili procijenjeni. Cilj ovog istraživanja bio je istražiti čimbenike povezane s ozljedama u cestovnom prometu i njihovom težinom u skupini od 200 sudionika cestovnih prometnih nesreća (CPN) iz Istočne Hrvatske. Postojanje ozljede kod sudionika CPN bilo je povezano s ruralnim prebivalištem (p=0,032), nižom razinom obrazovanja (p=0,001), nezaposlenošću (p=0,001), samačkim životom (p=0,014), ispod prosječnim samoprocijenjenim ekonomskim statusom (p=0,001), apstinencijom od alkohola (p=0,018), upotrebom lijekova (p=0,031), osjećajem životne ugroženosti u CPN (p<0,001), boli nakon CPN (p<0,001), hospitalizacijom nakon CPN (p<0,001), trajanjem hospitalizacije (p<0,001), operacijom nakon CPN (p=0,048), rehabilitacijom nakon CPN (p=0,001) i postojanjem simptoma PTSP-a (p=0,001). Težina ozljede bila je povezana s nižom razinom obrazovanja (p=0,013), nezaposlenošću (p=0,004), samačkim životom (p=0,017), ispod prosječnim samoprocijenjenim ekonomskim statusom (p<0,001), apstinencijom od alkohola (p=0,042), upotrebom lijekova (p=0,014), osjećajem životne ugroženosti u CPN (p<0,001), boli nakon CPN (p<0,001), sudjelovanjem u CPN u svojstvu pješaka ili biciklista (p=0,011), hospitalizacijom nakon CPN (p<0,001), trajanjem hospitalizacije (p<0,001), operacijom nakon CPN (p<0,001), rehabilitacijom nakon CPN (p=0,001), postojanjem simptoma depresije (p<0,001) i simptoma PTSP-a (p<0,001). Kako bi se adekvatnije spriječile ozljede u cestovnom prometu, znanje o čimbenicima povezanim s takvim ozljedama i njihovom težinom trebalo bi biti temelj za stvaranje posebnih programa prevencije na regionalnoj i nacionalnoj razini.

Finger length ratio (2D:4D) and aging [Elektronička građa] / Leonid Kalichman, Valery Batsevich, Eugene Kobyliansky. - Ilustr. ; graf. prikazi.
Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - This study aimed to evaluate the association between the index to ring (2D:4D) finger length ratio and aging-related traits (hand osteoarthritis (OA), the osseographic score (OSS), and reproductive period), as well as to assess the heritability of finger length. A Chuvashian population-based sample included 802 males (mean age 46.98±17.10 years) and 738 females (mean age 48.65±16.62 years). Age, sex, basic demographics, anthropometric data, reproductive indices (age at menarche, menopausal age, and length of the reproductive period), and x-rays of both hands were collected. Finger length ratio was measured on x-ray and each hand was visually classified as either type 1 – 2D>4D; type 2 ― 2D=4D; or type 3 ― 2D<4D. Hand OA was defined by the number of affected joints (Kellgren-Lawrence score ≥2) and the total of Kellgren-Lawrence scores (total OA score). OSS is a skeletal biomarker that comprises osteoporotic and OA changes observable on a hands x-ray. We calculated the familial correlations and performed a heritability analysis of 2D:4D ratio traits in a studied sample. After comparing the OA variables of individuals with different finger length ratio types (after adjustment for age and BMI) significant differences were found only in females between finger ratio types of the right hand in a number of affected joints (F=3.153, p=0. 043) and finger ratio types of the left (F=3.330, p=0. 036) and right (F=2.397, p=0. 047) hands of the total OA score. Females with type 3 ratio had the highest adjusted values of hand OA parameters. Results of one-way ANCOVA for finger length ratio types of the right hand showed a significant difference in OSS (df =2, F=7.569, P=0.001), after adjustment for age, sex, and BMI. The posthoc comparison showed that individuals with type 3 (2D<4D) ratio showed significantly higher OSS scores than ones with type 1 (p=0.012) and type 2 (p=0.003). - Ovo istraživanje imalo je za cilj procijeniti povezanost između omjera duljine kažiprsta i prstenjaka (2D: 4D) i pokazatelja starenja (osteoartritis šake (OA), oseografski rezultat (OSS) i reproduktivno razdoblje), kao i procijeniti nasljednost duljine prsta. U uzorku populacije iz Čuvašije obuhvaćeno je 802 muškarca (prosječna dob 46,98 ± 17,10 godina) i 738 žena (prosječna dob 48,65 ± 16,62 godine). Prikupljeni su podaci o dobi, spolu, osnovna demografija, antropometrijski podaci, reproduktivni indeksi (dob u menarhi, starost menopauze i duljina reproduktivnog razdoblja) i rendgenske snimke obje ruke. Omjer duljine prstiju izmjeren je na rendgenu i svaka ruka vizualno je klasificirana kao tip 1 - 2D>4D; tip 2 - 2D = 4D; ili 3 - 2D <4D. Osteoartritis šake OA definiran je brojem zahvaćenih zglobova (Kellgren-Lawrence-ova klasifikacija ≥2) i ukupnim vrijednostima Kellgren-Lawrence-ove ljestvice (ukupni OA-rezultat). OSS je skeletni biomarker koji sadrži osteoporotične i OA promjene koje se mogu primijetiti na rendgenu ruke. Izračunali smo obiteljske korelacije i izvršili analizu nasljednosti 2D: 4D indeksa u ispitivanom uzorku. Nakon usporedbe OA varijabli pojedinaca s različitim tipovima omjera duljine prstiju (nakon prilagodbe za dob i BMI), utvrđene su značajne razlike samo kod žena između tipova omjera prstiju desne ruke i broja zahvaćenih zglobova (F = 3.153, p = 0 043) i tipova omjera prstiju lijeve (F = 3.330, p = 0. 036) i desne (F = 2.397, p = 0. 047) ruke i ukupnih OA vrijednosti. Žene s omjerom tipa 3 imale su najviše prilagođene vrijednosti parametara OA šake. Rezultati jednosmjerne ANCOVA analize za tipove omjera duljine prsta desne ruke pokazali su značajnu razliku u OSS-u (df = 2, F = 7,569, P = 0,001), nakon prilagodbe za dob, spol i BMI. Posthoc usporedba pokazala je da su pojedinci s tipom 3 (2D <4D) pokazali značajno veće OSS vrijednosti od onih s tipom 1 (p = 0,012) i tipom 2 (p = 0,003).

The importance of molecular diagnostics and screening programs in monitoring and evaluation of colorectal cancer in the Republic of North Macedonia [Elektronička građa] Značaj molekularne dijagnostike i screening programa u praćenju i evaluaciji kolorektalnog karcinoma u Republici Sjevernoj Makedoniji / Jovanka Trpkovska, Nevenka Velickova. - Graf. prikazi.
Bibliografija: 11 jed. - Abstract ; Sažetak. - Colorectal cancer (CRC) is one of the most common malignant diseases (12 % of the total) that occurs with an incidence of 15 – 30 new cases per 100,000 population per year in European Union countries. The risk of this disease during life depends on many factors such as age, diet, physical activity, personal and family predisposition. Several preventive measures can reduce the number of colorectal cancer patients. First of all, the regular screening which allows the detection of precancerous polyps or cancer in the early stage and their successful surgical removal. The purpose of this paper is to highlight the importance of screening programs as a preventive measure for the early detection of colorectal cancer and to reduce the morbidity and mortality of this disease. The strategy for improving the early detection of colorectal cancer also implies availability of useful information about the importance of screening programs for everyone as well as educating health care staff about the program itself. Number of newly registered colorectal cancer cases in 2009 in the Republic North Macedonia stands at 547 with a rate of 26.7 compared to 2018 with 839 newly registered cases with a rate of 40.4 which clearly indicates an increasing trend of colorectal cancer. Multidisciplinary approach to early detection of colorectal cancer, continuity of Program funding and quality of services will lead to reduction of morbidity and mortality of this type of cancer. - Kolorektalni karcinom (CRC) jedna je od najčešćih zloćudnih bolesti (ukupno 12 %) koja se javlja s incidencijom od 15 do 30 novih slučajeva na 100 000 stanovnika godišnje u zemljama Europske unije. Rizik za nastanak ove bolesti tijekom života ovisi o mnogim čimbenicima kao što su dob, prehrana, tjelesna aktivnost, osobna i genetska predispozicija. Postoji niz preventivnih mjera kojima se može smanjiti broj oboljelih od karcinoma debelog crijeva. Navedeno je moguće obavljanjem redovitog pregleda koji omogućuje otkrivanje prekanceroznih polipa ili raka u ranoj fazi te njihovo uspješno kirurško uklanjanje. Svrha je ovog rada istaknuti važnost screening programa kao preventivne mjere za rano otkrivanje kolorektalnog karcinoma te smanjenje morbiditeta i smrtnosti uzrokovane ovom bolešću. Strategija za poboljšanje ranog otkrivanja karcinoma debelog crijeva također podrazumijeva bolje informiranje stanovništva o važnosti probirnih programa, kao i edukaciju zdravstvenog osoblja o samom programu. Broj novoregistriranih slučajeva karcinoma debelog crijeva u 2009. godini u Republici Sjevernoj Makedoniji iznosi 547 sa stopom od 26,7 u usporedbi s 2018. godinom s 839 novoregistriranih slučajeva sa stopom od 40,4 što jasno ukazuje na trend rasta kolorektalnog karcinoma. Multidisciplinarni pristup ranom otkrivanju raka debelog crijeva, kontinuitet financiranja Programa te kvaliteta zdravstvenih usluga dovest će do smanjenja morbiditeta i smrtnosti ove vrste karcinoma.

Incidence of lower limb amputation in diabetic patients in Osijek-Baranja County [Elektronička građa] / Silvija Canecki-Varžić, Iris Pavošević, Ines Bilić-Ćurčić, Dario Rahelić, Damir Kovač, Kristina Bojanić, Ivana Prpić-Križevac. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - Amputation of the lower limb (LLA) is one of the most feared adverse outcomes among diabetic patients. Our aim was to determine the incidence of amputation in diabetic patients in Osijek-Baranja County and to examine the possible correlation between clinical characteristics of the patients and the time elapsed before the first amputation. This was a tertiary-care-based retrospective study and included 925 diabetic patients who underwent non-traumatic lower limb amputation in the University Hospital Osijek from January 1st 2008 to December 31st 2018. Data on associated cardiovascular risk factors and clinical characteristics of the patients were collected from diabetic registry of the Department of diabetes and endocrinology. A total of 278 patients had all data for further analysis. There were 1551 LLAs over a ten year period. The incidence was 6.14 per 1,000 adults with diabetes. LLA rates per 1,000 adults with diabetes decreased by 29% between 2010 and 2013 and then increased by 76% between 2014 and 2018. In ten year period incidence of amputation in diabetic patients varied from 4 to 7.8 per 1000 persons-year. We observed the same pattern in both minor and major LLA but rates of amputation above knee steadily increased 2.7 times between 2010 and 2018 (from 0.69 to 1.83 per 1000 patients-year). The mean age of patients with LLA was 67.2 years, 66% were male, mean BMI was 29.6±4.8 kg/m2 and the mean duration of diabetes was 14.7±8.2 years. There was no association between smoking, arterial hypertension and hyperlipemia, ACE inhibitor use, statin use, antiplatelet use, CVD, neuropathy and duration of diabetes before first amputation. Only sulphonylurea and insulin therapy significantly prolonged the time before the first amputation (p = 0.00001, for each). In conclusion, our study confirmed high rate of lower limb amputation in diabetic patients in Osijek-Baranja County. - Amputacija donjih ekstremiteta za dijabetičke bolesnike predstavlja neželjeni ishod kojeg se najviše boje.Cilj našeg ispitivanja bio je odrediti kretanje godišnje stope amputacija donjih ekstremiteta u dijabetičkih bolesnika te ispitati povezanost između kliničkih značajki bolesnika i trajanja dijabetesa do prve amputacije. Ovo je presiječno retrospe153 S. Canecki-Varžić et al.: Amputation in Diabetics in Osijek-Baranja County, Coll. Antropol. 44 (2020) 3: 147–153 ktivno ispitivanje u tercijarnom centru obuhvatilo 925 dijabetičkih bolesnika kojima je učinjena netraumatska amputacija donjih ekstremiteta u razdoblju od 2008. do 2018.g u KBC Osijek. Prikupljeni su podaci iz registra Zavoda za endokrinologiju o kardiovaskularnim rizičnim čimbenicima i drugim kliničkim značajkama bolesnika. Za dodatne analize izdvojena je skupina od 278 pacijenata koji su imali podatke za daljnju analizu. U desetogodišnjem razdoblju bilo je 1551 amputacija donjih ekstremiteta. Incidencija stope amputacija iznosila je 6,14 na 1000 pacijent-godina. Stopa amputacija na 1000 pacijent-godina smanjila se za 29% između 2010.i 2013. godine te ponovo porasla na 76% od 2014.– 2018. Godišnja stopa varirala je od 4,0–7,8 amputacija na 1000 pacijent-godina. Isti obrazac registrirali smo za manje i veće amputacije, ali stopa amputacija iznad nivoa koljena postojano je rasla i od 2010. do 2018. g. povećala se 2,7 puta (od 0,69 na 1,83 amputacijana 1000 pacijent-godina). Prosječna dob pacijenata bila je 67,2 g, a 66% su činili muškarci, s prosječnim ITM 29,6±4,8 kg/m2 i trajanjem dijabetesa od 14,7±8,2 g. Nije ustanovljena povezanost između pušenja, arterijske hipertenzije, hiperlipidemije, terapije ACE inhibitorima i statinima, antiagregacijske terapije, KVB, te neuropatije i trajanja dijabetesa do prve amputacije. Samo prethodno liječenje sulfonilurejom i inzulinom značajno je produljilo vrijeme do prve amputacije (p=0,00001, za obje terapije).

Influence of caffeine on crystallization and amelioration of oxidative stress on in vitro model of urolithiasis [Elektronička građa] / Vjera Ninčević, Tomislav Kizivat, Tea Omanović Kolarić, Lucija Kuna, Anita Cindrić, Anamarija Banovac, Ines Bilić Ćurčić, Sandra Tucak-Zorić, Martina Smolić. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - Urolithiasis is a disease characterized by formation of solid crystals within the urinary tract. Kidney stone formation is still not clear but it is mostly composed of calcium oxalate which can produce free radicals that are toxic to renal tubular cells. Oxidative stress is an important contributory mechanism in cell damage and is associated with a number of disorders. Several studies have shown antioxidative effects of caffeine, proposing its possible role in stopping the formation of calcium oxalate stones in urinary tract. Hence, the aim of this study was to evaluate the toxic effects of calcium oxalate monohydrate crystals (COM) on renal epithelial cell line; Madin-Darby canine kidney cells subtype I (MDCK I) and Epithelial-like pig kidney cell line (LLC-PK1), and to determine possible inhibition of COM that caused oxidative stress by antioxidant treatment with caffeine in different concentrations in a cell culture model of urolithiasis. - Urolitijaza je bolest koju karakterizira stvaranje čvrstih kristala unutar mokraćnoga sustava. Mehanizam stvaranja bubrežnih kamenaca još je uvijek nejasan, a uglavnom se sastoji od kalcijevoga oksalata koji može proizvesti slobodne radikale toksične za bubrežne tubularne stanice. Oksidativni stres važan je mehanizam koji doprinosi oštećenju stanica i povezan je s nizom poremećaja. Nekoliko je studija pokazalo antioksidativne učinke kofeina, sugerirajući njegovu moguću ulogu u zaustavljanju stvaranja kalcijevih oksalatnih kamenaca u mokraćnim putovima. Stoga je cilj ovoga istraživanja bio procijeniti toksični učinak kristala kalcijevog oksalata monohidrata (COM) na staničnu liniju bubrežnoga epitela, Madin-Darbyjeve pseće stanice bubrega podtipa I (MDCK I) i epitelne stanice bubrega svinje (LLC-PK1), te utvrditi moguće inhibicije COM-a (uzroka oksidativnoga stresa) antioksidativnim tretmanom kofeinom u različitim koncentracijama na modelu stanične kulture urolitijaze.

Karakteristike jakosti kuka, gležnja i trupa kod osoba s patelofemoralnom boli [Elektronička građa] : razlike među spolovima / Denisa Manojlović, Nejc Šarabon. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Sažetak ; Summary. - Uvod: Patelofemoralna bol (PFB) jedna je od najučestalijih boli u području koljena. Smanjena jakost okolnih mišićnih skupina može prouzrokovati lokalne biomehaničke promjene, koje posljedično pridonose razvoju PFB-a. Cilj je našeg rada identificirati, usporediti i procijeniti značajke maksimalne izometričke kontrakcije (MVIC) mišića kuka, trupa i gležnja kod žena i muškaraca s PFB-om. Metode: Izveden je sustavni pregled literature te je za daljnju analizu izabrano devet istraživanja koja su odgovarala unaprijed postavljenim kriterijima. Rezultati: Znatno veći broj istraživanja proučava MVIC mišića kuka u žena s PFB-om nego u muškaraca s istom patologijom. Kod žena su istraživanja složna te izvještavaju o smanjenoj jakosti abduktora, aduktora i ekstenzora kuka, dok su u slučaju dvaju istraživanja koja su proučavala MVIC laterofleksora trupa rezultati oprečni. Našim pretraživanjem nisu nađena istraživanja koje proučavaju utjecaj MVIC-a gležnja kod PFB-a. Zaključak: U oba se spola područje kuka pokazalo potkrijepljeno znanstvenim istraživanjima te su rezultati MVIC-a kod PFB-a na tom području homogeni. Sustavnim pregledom trenutačno dostupne literature utvrđena je djelomična zastupljenost MVIC-a područja trupa kod osoba s PFB-om. Također, vidljiv je nedostatak znanstvenih istraživanja MVIC-a područja gležnja i stopala kako kod žena tako i kod muškaraca s PFB-om. - Introduction: Patelofemoral pain (PFP) is one of the most common pain conditions in the knee area. The reduced strength of the surrounding muscle groups can cause local biomechanical changes, which subsequently contribute to the development of PFP. The aim of our review is to compare and evaluate the maximal voluntary isometric contraction (MVIC) of the hip, trunk, and ankle muscles in men and women with PFP. Methods: A systematic review of the literature was performed and 9 studies were selected for further analysis that fit the preset criteria. Results: A significantly larger number of studies have studied hip MVIC in women with PFP than in men with the same pathology. Studies in women report reduced abductor, adductor and hip extensor strength, while in the case of two studies that examined lateral flexors of the trunk MVIC, the results were conflicting. Our search did not find any studies that examined the effect of MVIC of ankle or foot muscles on PFP in men or women. Conclusion: Regarding the MVIC in PFP, the hip area has proven to be the most scientifically examined in both man and women and the results are homogeneous. This systematic review of the currently available literature has identified the partial representation of the MVIC of the trunk area in individuals with PFP. Also, there is a lack of scientific research regarding the MVIC of the ankle and foot area in both women and men with PFP.

Knowledge and awareness of iodine intake - survey among Croatian women of reproductive age [Elektronička građa] / Valentina Vidranski, Anita Radman, Katarina Kajić, Ana Bronić. - Graf. prikazi.
Bibliografija: 18 jed. - Summary. - Introduction: Appropriate iodine intake is important for the entire population, especially in fertile women due to decisive role of thyroid hormones in normal foetal brain development. The aim of this study was to investigate knowledge on iodine role among Croatian women of reproductive age.Materials and methods: The survey was conducted among 378 women of reproductive age during May-September 2018. Data on age, education level, salt intake habits, knowledge of the iodine role and possible presence of thyroid disease were collected and results were presented as numbers or percentage of total number of participants. Comparison between groups was performed by Chi square test.Results: Of 378 participants, 178 reported to be familiar with the iodine role in the body (P = 0.115). Significantly higher proportion of the younger woman and woman with lower degree of education weren’t familiar with the iodine role (P <0.001). More woman were introduced to consequences of insufficient than to excessive iodine intake (273 vs 213; P <0.001). In addition, participants mainly weren’t familiar with obligation of salt iodination (P <0.001). Presence of thyroid disease was recorded in 75 subjects with higher prevalence in subjects 36-49 years (P <0.001). Presence of thyroid disease was not associated with knowledge on iodine role on health.Conclusion: Women of reproductive age are not completely aware of the consequences of excessive iodine intake. Thus, further education focusing on more sensitive groups such as woman of younger age should be considered in order to preserve their and their children’s health.

Laboratory markers included in the Corona score can identify false negative results on COVID-19 RT-PCR in the emergency room [Elektronička građa] / Roberto Assandri, Ciro Canetta, Giovanni Viganò, Elisabetta Buscarini, Alessandro Scartabellati, Alessandro Montanelli.
Bibliografija: 6 jed. - Summary. - After December 2019 outbreak in China, the novel Coronavirus infection (COVID-19) has very quickly overflowed worldwide. Infection causes a clinical syndrome encompassing a wide range of clinical features, from asymptomatic or oligosymptomatic course to acute respiratory distress and death. In a very recent work we preliminarily observed that several laboratory tests have been shown as characteristically altered in COVID-19. We aimed to use the Corona score, a validated point-based algorithm to predict the likelihood of COVID-19 infection in patients presenting at the Emergency rooms. This approach combines chest images-relative score and several laboratory parameters to classify emergency room patients. Corona score accuracy was satisfactory, increasing the detection of positive patients’ rate.

Nastavak iz br. 1/2020. - Bibliografija: 48 jed. - Summary. - Joint diseases are conditions with an often progressive and generally painful nature affecting the patient’s quality of life and, in some cases, requiring a prompt diagnosis in order to start the treatment urgently. Synovial fluid (SF) laboratory testing is an important part of a diagnostic evaluation of patients with joint diseases. Laboratory testing of SF can provide valuable information in establishing the diagnosis, be a part of a patient’s follow-up and treatment with the purpose of improving the patient’s health and quality of life. Synovial fluid laboratory testing is rarely performed in Croatian medical biochemistry laboratories. Consequently, procedures for SF laboratory testing are poorly harmonized. This document is the second in the series of recommendations prepared by the members of the Working group for extravascular body fluid samples of the Croatian Society of Medical Biochemistry and Laboratory Medicine. It addresses preanalytical, analytical, and postanalytical issues and the clinical significance of tests used in SF laboratory testing with the aim of improving the value of SF laboratory testing in the diagnosis of joint diseases and assisting in the achievement of national harmonization. It is intended for laboratory professionals and all medical personnel involved in synovial fluid collection and testing.

Percepcija lica u poremećaju iz spektra autizma [Elektronička građa] : od singularnih prema modularnim perspektivama / Ana Miličević, Vito Bošnjak, Mirta Stantić.
Bibliografija: str. 393-399. - Sažetak ; Summary. - U posljednjih se desetak godina u medijima često govori o povećanom broju dijagnosticiranih slučajeva autizma u djetinjstvu. U ovom sustavnom pregledu razmatramo razvoj razumijevanja percepcije lica, jedne od specifičnijih značajki autizma, u svjetlu komorbiditeta s aleksitimijom i uznapredovalih statističkih metodologija istraživanja. Navodimo literaturu koja se bavi percepcijom lica u autizmu u različitim kognitivnim zadacima i upućuje na važnost često komorbidne aleksitimije, kao i literaturu koja koristi neuroslikovne metode istraživanja i potvrđuje važnost različitih uzoraka gledanja u autizmu pri analizi rezultata. U svrhu poboljšane obrazovne i socijalne integracije osoba s autizmom i/ili aleksitimijom predlažemo teme za daljnje istraživanje. - In the last few decades, the media have continuously reported on the increased number of diagnosis of Autism Spectrum Disorder (ASD). This systematic review looks at the evolution of research on face perception, one of the characteristics of ASD, in the light of recently reported prevalence of alexythimia comorbidity, as well as improved statistical methods in cognitive research. We review the literature on behavioural face perception testing in autism, showing the importance of a prevalent comorbidity of alexythimia, as well as neural evidence showing the importance of differential eye gaze patterns in autism for data analysis. We suggest outstanding questions in the field in order to improve the integration of people with ASD and alexithymia into the educational and social contexts.

Platelet indices in stable chronic obstructive pulmonary disease - association with inflammatory markers, comorbidities and therapy [Elektronička građa] / Iva Hlapčić, Anita Somborac-Bačura, Sanja Popović-Grle, Andrea Vukić Dugac, Dunja Rogić, Ivana Rako, Tihana Žanić Grubišić, Lada Rumora. - Graf. prikazi.
Bibliografija: 30 jed. - Summary. - Chronic obstructive pulmonary disease (COPD) is a complex inflammatory condition that can affect haemostasis. This study aimed to determine differences in platelet-related parameters between controls and COPD subjects. The hypothesis was that platelet indices are disturbed in COPD patients, and this would be accompanied by increased C-reactive protein (CRP), fibrinogen (Fbg) and white blood cells (WBC). Therefore, platelet count (Plt), platelet-related parameters – mean platelet volume (MPV), platelet distribution width (PDW), plateletcrit (Pct), their ratios (MPV/Plt, MPV/Pct, PDW/Plt, PDW/Pct), platelet to lymphocyte ratio (PLR), Plt index as well as CRP, Fbg and WBC were assessed. Materials and methods: Study included 109 patients with stable COPD and 95 control subjects, recruited at Clinical Department for Lung Diseases Jordanovac, University Hospital Centre Zagreb (Zagreb, Croatia). Complete blood count was performed on Sysmex XN-1000, CRP on Cobas c501, and Fbg on BCS XP analyser. Data were analysed with MedCalc statistical software. Results: Platelet (P = 0.007) and PLR (P = 0.006) were increased, while other platelet indices were decreased in COPD patients compared to controls. Combined model that included PLR, PDW and WBC showed great diagnostic performances, and correctly classified 75% of cases with an AUC of 0.845 (0.788 – 0.892), P <0.001. Comorbidities (cardiovascular or metabolic diseases) had no effect on investigated parameters, while inhaled corticosteroids/long-acting β2-agonists (ICS/LABA) therapy increased MPV and PDW values in COPD patients. Conclusion: Platelet indices were altered in COPD patients and they could be valuable as diagnostic markers of COPD development, especially if combined with already known inflammatory markers.

Potential of modern circulating cell-free DNA diagnostic tools for detection of specific tumour cells in clinical practice [Elektronička građa] / Jernej Gašperšič, Alja Videtič Paska. - Graf. prikazi.
Bibliografija: 97 jed. - Summary. - Personalized medicine is a developing field of medicine that has gained in importance in recent decades. New diagnostic tests based on the analysis of circulating cell-free DNA (cfDNA) were developed as a tool of diagnosing different cancer types. By detecting the subpopulation of mutated DNA from cancer cells, it is possible to detect the presence of a specific tumour in early stages of the disease. Mutation analysis is performed by quantitative polymerase chain reaction (qPCR) or the next generation sequencing (NGS), however, cfDNA protocols need to be modified carefully in preanalytical, analytical, and postanalytical stages. To further improve treatment of cancer the Food and Drug Administration approved more than 20 companion diagnostic tests that combine cancer drugs with highly efficient genetic diagnostic tools. Tools detect mutations in the DNA originating from cancer cells directly through the subpopulation of cfDNA, the circular tumour DNA (ctDNA) analysis or with visualization of cells through intracellular DNA probes. A large number of ctDNA tests in clinical studies demonstrate the importance of new findings in the field of cancer diagnosis. We describe the innovations in personalized medicine: techniques for detecting ctDNA and genomic DNA (gDNA) mutations approved Food and Drug Administration companion genetic diagnostics, candidate genes for assembling the cancer NGS panels, and a brief mention of the multitude of cfDNA currently in clinical trials. Additionally, an overview of the development steps of the diagnostic tools will refresh and expand the knowledge of clinics and geneticists for research opportunities beyond the development phases.

Vidi i dodatak članku u br. 2/2020, str. 338-339. - Bibliografija: 27 jed. - Summary. - Introduction: Diabetes mellitus (DM) is one of the most prevalent diseases worldwide. The objective of this study was to find out under what preanalytical conditions routine and diagnostic glucose tests are performed across Spanish laboratories; and also what criteria are used for DM diagnosis.Materials and methods: An online survey was performed by the Commission on Quality Assurance in the Extra-Analytical Phase of the Spanish Society of Laboratory Medicine (SEQC-ML). Access to the questionnaire was available on the home page of the SEQC-ML website during the period April-July 2018. Data analysis was conducted with the IBM SPSS© Statistics (version 20.0) program.Results: A total of 96 valid surveys were obtained. Most laboratories were in public ownership, serving hospital and primary care patients, with high and medium workloads, and a predominance of mixed routine-urgent glucose testing. Serum tubes were the most used for routine glucose analysis (92%) and DM diagnosis (54%); followed by lithium-heparin plasma tubes (62%), intended primarily for urgent glucose testing; point-of care testing devices were used by 37%; and plasma tubes with a glycolysis inhibitor, mainly sodium fluoride, by 19%. Laboratories used the cut-off values and criteria recognized worldwide for DM diagnosis in adults and glucose-impaired tolerance, but diverged in terms of fasting plasma glucose and gestational DM criteria.Conclusion: Preanalytical processing of routine and DM diagnostic glucose testing in Spain does not allow a significant, non-quantified influence of glycolysis on the results to be ruled out. Possible adverse consequences include a delay in diagnosis and possible under-treatment.

Pretraživanje zdravstvenih informacija na internetu - implikacije za zdravstvenu anksioznost kod starijih osoba [Elektronička građa] / Branka Bagarić, Nataša Jokić-Begić. - Graf. prikazi.
Bibliografija: str. 417-425. - Sažetak ; Summary. - Pretraživanje o zdravlju na internetu postalo je vrlo rašireno. Kako starije osobe imaju više zdravstvenih problema, mogle bi postati sve veći konzumenti digitalnih zdravstvenih sadržaja. No, budući da imaju slabije računalne vještine te da nisu naviknute na ulogu „osnaženog pacijenta“, mogle bi doživjeti pretjeranu zabrinutost dok pretražuju o svojim simptomima. Istraživanja sugeriraju da je pretraživanje o zdravlju na internetu potencijalni rizični faktor za patološku zdravstvenu anksioznost, a možda na poseban način djeluje upravo na starije osobe. Istraživanja o pretraživanju kod starijih malobrojna su i uglavnom provedena bez jasnog teorijskog okvira što otežava smislenu interpretaciju i integraciju njihovih nalaza. Stoga je cilj ovoga preglednog rada ponuditi takav teorijski okvir (Leventhalov model zdravorazumske regulacije) te dati pregled nalaza dosadašnjih istraživanja u području integrirajući ih u predloženi model. Ovaj model predviđa da dob i dobne promjene u doživljaju sebe rezultiraju promjenama u zdravstvenim kognicijama i ponašanjima. Pretraživanje o zdravlju na internetu može se konceptualizirati kao strategija suočavanja i sa zdravstvenom prijetnjom i emocionalnom neugodom, a koja ima posljedice na kognitivne reprezentacije bolesti (identitet, uzrok, posljedice, mogućnost kontrole i vremensku dimenziju), zdravstvena ponašanja i ishode. Polazeći od pretpostavki modela, raspravljeno je kako pretraživanje može rezultirati zdravstvenom anksioznošću. Na kraju su pružene smjernice za buduća istraživanja i razmotrene njihove praktične implikacije. - Health information seeking on the Internet has become widespread. Since the elderly experience more health issues, they might become more frequent users of digital health content. But, since their computer skills are less advanced and since they are not used to the role of the „empowered patient“, researching their symptoms online might result in excessive anxiety. Research suggests that health information seeking might be a risk factor for pathological health anxiety, yet it may have a specific effect on the elderly. Studies on health information seeking in older adults are sparse and mostly conducted without a clear theoretical framework which complicates meaningful interpretation and integration of their findings. Therefore, the aim of this review paper is to propose such theoretical framework; Leventhal’s Common-sense model of self-regulation, and to review findings of previous studies in the area integrating them in the proposed model. According to this model, ageing and age-related changes in the self, affect health-related cognitions and behaviours. Health information seeking may be conceptualized as a coping response to both health threat and emotional discomfort, which has consequences on illness representations (identity, cause, consequences, control, and timeline), health behaviours and outcomes. Special emphasis was placed to a way in which health information seeking online can result in health anxiety according to the proposed model. Finally, avenues for future research are provided and their practical implications considered.

The prevalence of dementia in Europe and in Slovenia [Elektronička građa] : the review and estimate of dementia for Slovenia for 2018 and projection for 2030 / Barbara Lovrečić, Marjetka Jelenc, Aleš Korošec, Maruška Vidovič, Mercedes Lovrečić. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - Dementia is becoming an increasingly important public health priority that will continue to increase due to the population aging and longevity. Appropriate national assessment of dementia prevalence is essential for properly planing the actions needed to address dementia. The purpose of this work was to identify the known prevalence of dementia in Europe and in Slovenia in the last twenty years, as well as to produce an estimation for 2018 and a projection for 2030 based on population data in Slovenia. The PubMed database search engine was used. We searched for hits in various combinations and reviewed the literature on the prevalence of dementia in Europe and in Slovenia. Estimates of dementia revalence for Slovenia were not found in the reviewed literature; we calculated it based on Slovenian data for 2018 and projections for 2030. Dementia prevalence rates in Europe have not changed significantly in most age groups in recent decades. In Slovenia, in 2018, the age-standardized prevalence rate for those aged 65 and over was 6.9%, for women 8.8% and for men twice lower, and according to the projection for 2030 it was 7.2% for men, 9.0% for women, which was twice as much as in men. The gross prevalence rate for dementia in people aged 65 and older in Europe ranges from 5.9% to 9.4%. The results of all studies show that the prevalence is increasing with increasing age, that it is higher and it is increasing earlier and faster in women (80–84 years) compared to men (85–89 years). The prevalence of dementia in women was twice as high as that of men and was increasing more rapidly with age. In Slovenia we can expect an increase in the number of people with dementia in the next ten years, primarily due to the aging of the population and extending of the life expectancy. - Demencija postaje sve važniji prioritet za javno zdravstvo koji će se nastaviti povećavati zbog starenja i dugovječnosti stanovništva. Odgovarajuća nacionalna procjena prevalencije demencije ključna je za pravilno planiranje aktivnosti potrebnih za rješavanje problema demencije. Svrha ovog rada bila je identificirati poznatu prevalenciju demencije u Europi i Sloveniji u posljednjih dvadeset godina, kao i izraditi procjenu za 2018. i projekciju za 2030. na temelju podataka o broju stanovnika u Sloveniji. Upotrijebljena je bila tražilica baze podataka PubMed. Tražili smo nazive u raznim kombinacijama i pregledali literaturu o rasprostranjenosti demencije u Europi i Sloveniji. U recenziranoj literaturi nismo pronašli procjene prevalencije demencije za Sloveniju; izračunali smo ju na temelju slovenskih podataka za 2018. godinu i projekcija za 2030. Stopa prevalencije demencije u Europi nije se značajno promijenila u većini dobnih skupina posljednjih desetljeća. U Sloveniji je u 2018. godini standardizirana stopa prevalencije za starije od 65 godina bila 6,9%, za žene 8,8%, a za muškarce dvostruko niža, a prema projekciji za 2030. bila je za muškarce 7,2%, za žene 9,0%, što je dvostruko više nego kod muškaraca. Gruba stopa prevalencije demencije kod ljudi starijih od 65 godina u Europi kreće se od 5,9% do 9,4%. Rezultati svih studija pokazuju da je prevalencija u porastu s porastom dobi, da je veća i da se povećava ranije i brže kod žena (80-84 godina) u usporedbi s muškarcima (85-89 godina). Prevalencija demencije kod žena bila je dvostruko veća nego kod muškaraca i s godinama se brže povećavala. U Sloveniji možemo očekivati porast broja oboljelih od demencije u sljedećih deset godina, prije svega zbog starenja stanovništva i produljenja životnog vijeka.

Prognostic indicators for first and repeated hospitalizations in heart failure patients with reduced left ventricular ejection fraction [Elektronička građa] / Kristina Selthofer-Relatić, Mato Tomić, Anto Stažić, Jerko Arambašić, Kristina Kralik, Jure Mirat. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - Heart failure with reduced ejection fraction (HFrEF) is a progressive clinical syndrome defined by changes in the myocardial structure, which lead to predominant systolic myocardial function impairment, with a left ventricle ejection of fraction ≤40%. The rehospitalization burden in HFrEF patients (pts) remains very high, with poor quality of life, increased mortality and large healthcare expenditures. In this research project, we investigated the risk factors for first and repeated hospitalization in pts with HFrEF. This retrospective study included 50 adult pts with a diagnosis of HFrEF and who were within the age range of 55 to 89 years old and of both sexes. Demographic and clinical data (HFrEF etiology, renal function parameters, complete blood count, markers of nflammation, electrocardiogram, troponin I, NTproBNP, echocardiographic parameters and comorbidities data) were collected from the pts’ medical histories. Statistical analysis was performed via Fischer’s exact test, the Shapiro-Wilk test and the Spearman correlation coefficient. This study included 70% male and 30% female HFrEF pts. Males were younger in both group of pts and had a higher incidence of rehospitalization. The most important HFrEF etiologic risk factors are arterial hypertension (82%), coronary heart disease (54%), atrial fibrillation (52%) and diabetes mellitus (40%). The most important noncardiac comorbidity related with the first HFrEF hospitalization is pneumonia (P=0.03), while progression of left ventricle systolic and diastolic dysfunction is related to rehospitalization risk (left ventricle end systolic diameter, P=0.003; diastolic dysfunction degree, P=0.04). The troponin level was associated with an increased risk of rehospitalization, but this was not statistically significant at this sample size (troponin I, p=0.10). - Srčano popuštanje s reduciranom ejekcijskom frakcijom (HFrEF) progresivni je klinički sindrom definiran strukturnim promjenama miokarda koji dovodi prvenstveno do oštećenja sistoličke funkcije s redukcijom ejekcijske frakcije lijeve klijetke ≤40 %. Učestalost ponovne hospitalizacije pacijenata s HfrEF-om vrlo je visoka, smanjuje kvalitetu života, povećava stopu smrtnosti i veliko je financijsko opterećenje zdravstvenome sustavu. U istraživanju su proučavani rizični čimbenici za prvu i ponovnu hospitalizaciju kod pacijenata s HfrEF-om. U ovu retrospektivnu studiju uključeno je 50 odraslih pacijenata s dijagnozom HfrEF-a, životne dobi između 55 i 89 godina, oba spola. Demografski i klinički podaci (etiologija HfrEF-a, parametri bubrežne funkcije, kompletna krvna slika, biljezi upale, elektrokardiogram, troponin I, NTproBNP, ehokardiografski parametri, komorbiditeti) prikupljeni su iz medicinske dokumentacije pacijenata. Statistička analiza učinjena je Fischerovim egzaktnim testom, Shapiro-Wilk testom i Spearmanovim koeficijentom korelacije. U studiju je uključeno 70% muškaraca i 30% žena s HfrEF-om, muškarci su u obje praćene skupine bili mlađe životne dobi te su imali veću incidenciju rehospitalizacije. Najznačajniji etiološki čimbenici rizika za HFrEF su arterijska hipertenzija (82%), koronarna bolest (54%), atrijska fibrilacija (52%), šećerna bolest (40%). Od nekardioloških komorbiditeta vezanih uz prvu hospitalizaciju pacijenata s HfrEF-om najznačajnija je pneumonija (P = 0,03), dok je pogoršanje sistoličke i dijastoličke funkcije lijeve klijetke vezano uz ponovnu hospitalizaciju (end-sistolički promjer lijeve klijetke, P = 0,003; stupanj dijastoličke disfunkcije, P = 0,04). Biomarker troponin I pokazao je tendenciju porasta u rehospitalizaciji, ali bez statističke značajnosti na ovoj veličini uzorka (troponin I, p = 0,10).

Recommendations for people with osteoporosis and general practitioners during COVID-19 pandemic [Elektronička građa] / Blaženka Miškić, Vesna Ćosić, Aleksandar Včev, Karla Miškić, Ines Rajkovača-Latić, Željka Dujmić. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - The paper presents the guidelines made by the Multidisciplinary Team for Osteoporosis for patients in the General Hospital “Dr.Josip Benčević”, Slavonski Brod and general practitioners in the Brod-Posavina County in order to inform them properly about the COVID-19 pandemic and the recommendations of the National Civil Protection Committee, as well as to help them reduce their fear and to improve their cooperation with their general practitioners. A system of recording new fractures in the county was maintained since the onset of the epidemic. The recommendations for patients with osteoporosis include their lifestyle, medical treatment and balanced nutrition, following the advices of the International Osteoporosis Foundation, the Croatian Osteoporosis Society and the British Royal Osteoporosis Society. Living with osteoporosis demands balanced nutrition, regular exercise and taking prescribed medications. As in the present conditions of COVID-19 epidemic outdoor physical activities are temporarily limited it is necessary to ensure the availability of calcium-rich food and vitamin D supplies. As medical treatment of osteoporosis does not increase risk of COVID-19 infection it is recommended for patients to continue their prescribed therapy in consultation with their general practitioner. - Multidisciplinarni tim za osteoporozu (MDTOP) OB „Dr. Josip Benčević” Slavonski Brod pripremio je preporuke za postupanje u pandemiji COVID-19 za osobe sa osteoporozom i za liječnike obiteljske medicine u cilju smanjenja straha naših pacjenata i lakšu suradnju s liječnicima obiteljske medicine u novonastaloj situaciji. Pokušali smo zadržati i sistem evidentiranja novih prijeloma u tom periodu. Življenje s osteoporozom zahtijeva održavanje određenog načina prehrane, tjelovježbe i uzimanja propisane terapije. U sadašnjim uvjetima epidemije COVID-19 ograničava se privremeno tjelesna aktivnost u vanjskim uvjetima. Potrebno je uz mjere samoizolacije i socijalne distance osigurati opskrbu hranom bogatom kalcijem i vitaminom D. Lijekovi za liječenje osteoporoze ne povećavaju rizik oboljevanja od COVID-19 infekcije pa se preporuča nastaviti propisanu terapiju uz konzultaciju sa svojim liječnikom. U preporukama je naglašen razmjer pandemije i moguće posljedice za oboljele od osteoporoze. Opisana je klinička slika i ponovljene preporuke Nacionalnog stožera civilne zaštite kako živjeti u doba pandemije. Predložene su mjere tjelesne aktivnosti, prehrane i propisivanja terapije za osteoporozu u skladu s preporukama Međunarodne fundacije za osteoporozu, Britanskog kraljevskog društva za osteoporozu i Hrvatskim smjernicama za osteoporozu. Liječnicima obiteljske medicine su poslane upute o monitoriranju terapije tijekom pandemije.

Simple thrombin-based method for eliminating fibrinogen interference in serum protein electrophoresis of haemodialysed patients [Elektronička građa] / Anamarija Rade, Anamarija Đuras, Irena Kocijan, Patricija Banković Radovanović, Ana Turčić. - Ilustr., graf. prikazi.
Bibliografija: 27 jed. - Summary. - Introduction: Serum samples of haemodialysed patients collected through vascular access devices, e.g. central venous catheter (CVC) can contain residual heparin, which can cause incomplete clotting and consequently fibrinogen interference in serum protein electrophoresis (SPE). We hypothesized that this problem may be overcome by addition of thrombin and aimed to find a simple thrombin-based method for fibrinogen interference removal. Materials and methods: Blood samples of 51 haemodialysed patients with CVC were drawn through catheter into Clot Activator Tube (CAT) and Rapid Serum Tube Thrombin (RST) vacutainers (Becton Dickinson, New Jersey, USA) following the routine hospital protocols and analysed with gel-electrophoresis (Sebia, Lisses, France). Samples were redrawn in the CAT tubes and re-analysed after being treated with thrombin using two methods: transferring CAT serum into RST vacutainer and treatment of CAT serum with fibrinogen reagent (Multifibren U, Siemens, Marburg, Germany). Results: Direct blood collection in RST proved to be slightly more efficient than CAT in removing the interfering band in beta fraction (CAT removed 6/51 and RST removed 12/51, P = 0.031). Transferring CAT serum into the RST vacutainer proved to be more efficient for subsequent removal of interfering band from CAT serum than the addition of fibrinogen reagent (39/45 vs. 0/45 samples with efficiently removed interfering band, P <0.001). Conclusion: Fibrinogen interference caused by incomplete clotting because of residual heparin can be overcome by addition of thrombin. Transferring CAT serum into the RST vacutainer was the most efficient method.

Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - Introduction: Hypertension is one of the commonest non-communicable diseases worldwide; it is the second most common cause of end-stage renal disease. Objective: To evaluate the renal dimensions and volume of essential hypertension patients in Abubakar Tafawa Balewa University Teaching Hospital, Bauchi and to compare the dimensions with that of apparently healthy volunteers. Materials and Methods: A total of two hundred and eleven individuals (comprising 121 females and 90 males) with essential hypertension attending an outpatient clinic in Abubakar Tafawa Balewa University Teaching Hospital Bauchi, and an equal number of healthy volunteers (comprising of 172 females and 49 males) were studied as controls. Both the healthy volunteers and the Hypertensive patients’ renal length, renal width, antero-posterior diameter, and parenchymal thickness were assessed. Statistical Package for Social Sciences (SPSS version 20.0) was used for data analysis. Results: Study show the mean renal length for hypertensive patients to be 9.1 ± 0.79 cm and 9.1 ± 0.73 cm, the mean renal width of 3.5 ± 0.48 cm and 3.8 ± 0.68 cm, and mean renal volume of 87.22 ± 19.58 cm3 and 95.08 ± 22.93 cm3 for the right and left kidneys respectively. Results equally show statistically significant difference in anteroposterior diameter (p<0.05), parenchymal thickness (p<0.05) and renal volume (p<0.05) between the hypertensive group and the volunteer group for both right and left kidneys. Conclusion: This study has established baseline renal dimensions for hypertensive in our population (Bauchi Metropolis). The hypertensive subjects showed a decrease in renal anteroposterior diameter, parenchymal thickness and volume compared to control group. - Uvod: Hipertenzija je jedna od najčešćih nezaraznih bolesti u svijetu; drugi je najčešći uzrok završnog stadija bubrežne bolesti. Cilj: Procijeniti dimenzije bubrega i bubrežni volumen kod hipertenzivnih bolesnika u Sveučilišnoj bolnici Abubakar Tafawa Balewa u gradu Bauchi i usporediti ih s dimenzijama kod naizgled zdravih ispitanika koji su se dobrovoljno javili za sudjelovanje u istraživanju. Materijali i metode: Uzorak se sastojao od dvjesto jedanaest ispitanika (121 žena i 90 muškaraca) koji boluju od esencijalne hipertenzije i na ambulantnom su liječenju u Sveučilišnoj bolnici Abubakar Tafawa Balewa u gradu Bauchi i jednakog broja zdravih ispitanika (172 žene i 49 muškaraca), koji su bili kontrolna skupina. Proučavana je duljina i širina bubrega, anteroposteriorni promjer i debljina parenhima kod ispitanika s hipertenzijom i kod zdravih ispitanika. Za analizu podataka primijenjen je statistički paket za društvene znanosti (SPSS verzija 20.0). Rezultati: Studija pokazuje da je prosječna dužina bubrega kod hipertenzivnih bolesnika 9,1 ± 0,79 cm i 9,1 ± 0,73 cm, prosječna bubrežna širina 3,5 ± 0,48 cm i 3,8 ± 0,68 cm, a prosječni bubrežni volumen 87,22 ± 19,58 cm3 i 95,08 ± 22,93 cm3 za desni i lijevi bubreg pojedinačno. Rezultati također pokazuju statistički značajnu razliku u anteroposteriornom promjeru (p <0,05), debljini parenhima (p <0,05) i bubrežnom volumenu (p <0,05) između hipertenzivne skupine i kontrolne skupine za desni i lijevi bubreg. Zaključak: Ovom su studijom utvrđene osnovne bubrežne dimenzije kod hipertenzivnih bolesnika u populaciji grada Bauchi, glavnog grada Savezne države Bauchi u Nigeriji. Kod ispitanika koji boluju od hipertenzije ustanovljeno je smanjenje anteroposteriornog promjera bubrega, debljine parenhima i bubrežnog volumena u usporedbi s kontrolnom skupinom.

An unconscious man with profound drug-induced hypoglycaemia [Elektronička građa] / Toon Schiemsky, Guy Vundelinckx, Kathleen Croes, Joris Penders, Koen Desmet, Steven Pauwels, Pieter Vermeersch. - Graf. prikazi.
Bibliografija: 15 jed. - Summary. - Introduction: Hypoglycaemia has been reported as an unusual complication of tramadol use and in a few cases of tramadol poisoning, but theexact mechanism is not known.Case description: An ambulance crew was dispatched to an unconscious 46-year old man. A glucometer point-of-care measurement revealed aprofound hypoglycaemia (1.9 mmol/L). Treatment with intravenous glucose was started and the patient was transported to the hospital. The patienthad several episodes of pulseless electrical activity requiring cardiopulmonary resuscitation in the ambulance and upon arrival in the hospital.Despite continuous glucose infusion the hypoglycaemia was difficult to correct during the next few hours and the patient developed hypokalaemia.Further investigation to identify the cause of hypoglycaemia revealed that insulin and C-peptide were inappropriately raised. A toxicological investigationrevealed the presence of tramadol and its metabolites in lethal concentrations. Also acetaminophen, ibuprofen and lormetazepam werepresent. Ethanol screening was negative (<0.1 g/L) and no sulfonylurea were detected. The patient developed multiple organ failure, but eventuallyrecovered.What happened: The hypoglycaemia was caused by inappropriate stimulation of insulin secretion in a patient intoxicated with tramadol. Thesudden hypokalaemia was caused by a massive intracellular shift of potassium in response to the hyperinsulinemia, triggered by the intravenousadministration of glucose.Main lesson: To our knowledge, we are the first to document a significant rise in endogenous insulin production in a hypoglycaemic patient presentingwith tramadol intoxication. Our observation suggests that hyperinsulinemia could be the cause of the hypoglycaemia associated with tramadoluse.

Verification of the Canadian Laboratory Initiative on Paediatric Reference Intervals (CALIPER) reference values in Croatian children and adolescents [Elektronička građa] / Renata Zrinski Topić, Jasna Leniček Krleža. - Graf. prikazi.
Bibliografija: 14 jed. - Summary. - Introduction: The aim of this study was to examine whether the Canadian Laboratory Initiative on Paediatric Reference Intervals (CALIPER) couldbe applied to Croatian children and adolescents.Materials and methods: A total of 295 outpatient healthy children and adolescents of age 1 to 18 were selected using the direct a posteriorisampling method. According to current guidelines, 20 samples were tested for each of a total of 51 reference intervals for ferritin, cortisol, dehydroepiandrosteronesulfate, follicle stimulating hormone, lutein stimulating hormone, prolactin, progesterone, sex hormone binding globulin, thyroidstimulating hormone, total testosterone, total thyroxine and total triiodothyronine. Serum samples were analysed on the Beckman Coulter DxI600immunoassay analyser by chemiluminescence immunoassay method. A reference interval was adopted if <10% of the results fall outside CALIPERreference interval range. For analytes in which this criterion is not met in the first set of samples, a new set of 20 samples were collected.Results: After the first set of measurements, 96% of all tested reference intervals were adopted for use. The additional sets of 20 reference subjectswere tested for only two reference intervals; follicle stimulating hormone for female aged 1 to 9 years, and irrespective of the gender, sex hormonebinding globulin for children aged 8 to 11 years. All results of additional samples were within the specified interval limits.Conclusions: CALIPER reference intervals for ferritin and 11 hormones defined for Beckman Coulter DxI600 immunoassay analyser can be implementedinto the Croatian laboratories and clinical practice.

Accuracy of measurements performed on digital panoramic radiographs with and without an extra-oral calibration object [Elektronička građa] / Anita Ivanović, Frane Mihanović. - Ilustr., graf. prikazi.
Bibliografija: 30 jed. - Summary. - To investigate the accuracy of measurements in vertical and horizontal direction using an extra-oral calibration object placed in different positions on the panoramic radiograph in JPEG and DICOM image format. Methods: Digital panoramic radiographs of a purpose made model with 32 removable teeth replaced with metal balls were taken. The measurements of metal balls were performed with and without the calibration object placed in the middle or on the side of the radiograph in JPEG and DICOM image formats. Results: One sample t-test was used for the analyses of accuracy of measurements in vertical and horizontal direction. The most accurate vertical measurements were achieved in canine group in JPEG (6.02±0.04 mm, P=0.144) and DICOM (6.03±0.07 mm, P=0.104) formats using calibration object placed in the middle of the radiograph. The mean values of measurements in horizontal direction differed significantly from the real values (P<0.05) in all teeth groups regardless of the image format. Conclusion: The most accurate measurements in vertical direction were achieved by placing the metal scale ruler extra-orally in the middle of panoramic radiograph independent of the image format. Reliable clinical accuracy for measurements in horizontal direction was achieved only in canine region (G2) in both image formats.

Correlation of the expression of hyaluronan and CD44 with the presence of gingival inflammatory infiltrate in advanced generalized periodontitis [Elektronička građa] / Ivna Ćavar, Darko Kero. - Ilustr., graf. prikazi.
Bibliografija: 22 jed. - Summary. - To investigate the association between the expression of hyaluronan (HA) and its main receptor CD44 with the presence of inflammatory infiltrate in gingiva samples of patients suffering from advanced generalized periodontitis. Material and Methods: Samples of gingival tissue from healthy donors (controls, n = 20) and patients suffering from advanced generalized periodontitis stage 3 and 4 (test group, n = 20) were obtained. For immunofluorescence (IF) staining, primary antibodies against HA, CD44 and general inflammatory cell marker CD45 were used. The microscopic slides were photographed and panoramic images were edited in Adobe Photoshop®. The quantification of IF signal expression domains and spatial gradients was performed in ImageJ. The Microsoft Office Excel 2016 and GraphPad v8 software ware used for statistical analysis. Results: HA and CD44 were found to be widely expressed in the epithelium and subepithelial stroma of both healthy and diseased gingiva, including the areas of the gingiva containing the inflammatory infiltrate. No difference in the total expression of HA and CD44 in healthy and diseased gingiva was found. However, the pattern of distribution of HA and CD44 signals was somewhat different between the two groups of samples with regard to a statistically significant increase in stromal expression of HA and CD44 in diseased gingiva compared to healthy gingiva. No spatial correlation between HA and CD44 expression with the presence of inflammatory infiltrate was found in diseased gingiva. Moderate spatial correlation between HA and CD44 was found in diseased gingiva. Conclusion: HA and CD44 might play a role in the regulation of inflammatory response in advanced generalized periodontitis. However, further studies are needed in order to properly characterize such role of both investigated factors.

Knowledge on pre-hospital emergency management of tooth avulsion among Croatian kindergarten teachers [Elektronička građa] / Zvonimir Užarević, Zrinka Ivanišević, Tena Velki, Vesnica Mlinarević, Vedrana Nikolašević, Nikola Matijević, Marko Matijević. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - The aim of this study was to evaluate knowledge on pre-hospital emergency management of tooth avulsion among Croatian kindergarten teachers. A cross-sectional study was conducted among 33 educators in kindergarten (average 43.9±9.7 years). The questionnaire contained 10 close-ended questions with two or eleven possible answers. Statistical significance was determined using chi-square test. Majority of participants had no experience with tooth injury among children in kindergarten. Questions about the familiarity with the terms of a knocked-out tooth and tooth replantation and whether the knocked-out tooth should be replanted were confirmatively answered by 90.9%, 57.6% and 63.6% of participants, respectively. Only 9.1% of participants provided the correct answer that replantation should be done within 30 minutes. 78.8% of participants would choose correct medium for cleaning if avulsed tooth got dirty. Tooth would be transported in appropriate medium by 48.5% of participants. Correct answers on both the transport medium and the cleaning of knocked-out tooth were provided by 45.5% participants. 57.6% participants would seek help for replantation by visiting the nearest dentist. None of the participants had ever received any kind of information on management of a knocked-out tooth. The kindergarten teachers have a lack of knowledge for immediate response to tooth avulsion. Every kindergarten teacher should be well informed what should be done if some type of dental injury happens. The official communication between dental professionals and kindergarten teachers should be improved at local and regional level. - Cilj ovog istraživanja bio je procijeniti znanje hrvatskih odgojitelja o zbrinjavanju avulzije zuba prije ambulantnog liječenja. Presječno istraživanje provedeno je sa 33 odgojitelja u dječjim vrtićima (prosječne starosti 43,9 ± 9,7 godina). Upitnik je sadržavao 10 pitanja s dva do jedanaest mogućih odgovora. Statistička značajnost utvrđena je hi-kvadrat testom. Većina ispitanika nije imala iskustva s ozljedom zuba kod djece vrtićke dobi. Na pitanja o poznavanju pojmova izbijenog zuba, reimplantacije zuba i da li je potrebno izbijeni zub reimplantirati potvrdno je odgovorilo 90,9%, 57,6% odnosno 63,6% ispitanika. Samo je 9,1% ispitanika točno odgovorilo da bi reimplantaciju zuba trebalo obaviti u periodu od 30 minuta. Ukupno 78,8% ispitanika izabralo bi ispravan medij za čišćenje ako je izbijeni zub onečišćen. Zub bi u odgovarajućem mediju transportiralo 48,5% ispitanika. Točne odgovore o vrsti transportnog medija i čišćenju izbijenog zuba dalo je 45,5% ispitanika. Ukupno 57,6% ispitanika zatražilo bi pomoć za reimplantaciju zuba kod najbližeg doktora dentalne medicine. Nijedan ispitanik nikada nije dobio nikakvu informaciju o liječenju izbijenog zuba. Odgojitelji u dječjem vrtiću nemaju dovoljno znanja za hitno zbrinjavanje prilikom avulzije zuba. Svi odgojitelji u dječjim vrtićima trebali bi biti dobro informirani o tome kako postupiti prilikom ozljede zuba. Komunikaciju između doktora dentalne medicine i odgojitelja u dječjim vrtićima potrebno je poboljšati na lokalnoj i regionalnoj razini.

Use of cone beam computed tomography for studying temporomandibular joint morphology [Elektronička građa] / Ivan Lukšić, Žiga Lužnik, Ivica Pelivan, Samir Čimić. - Ilustr.
Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - The aim of the present study was to investigate morphology of temporomandibular joint using cone beam computer tomography. Study included 45 adults (32 females and 13 males). Articular eminence inclination, glenoid fossa width, glenoid fossa depth, condylar mediolateral distance, condylar anteroposterior distance and condylar type were determined for each temporomandibular joint. Since independent samples t-test did not show significant differences between left and right sides for all of observed parameters (p≥0.05), left and right side values were treated as one sample. The determined glenoid fossa depth was 7.11±2.23, glenoid fossa width 19.22±2.58, condylar anteroposterior distance 7.54±1.59, condylar mediolateral distance 17.95±2.81 and articular eminence inclination was 34.59±7.35 degrees. Most of condyles were classified as convex type (32.5%), followed by flattened (23.8%), rounded (11.3%) and angled (10%). Undefined (other type) were classified 22.5% of condyles. Cone beam computer tomography measurements of temporomandibular joint bone structures in present study showed similarities to most of previous research (with different populations studied). Still, the prevalence of different condylar types differs from those obtained by most of previous studies. Interindividual differences in temporomandibular joint morphology are expected. - Svrha ove studije bila je istražiti morfologiju temporomandibularnog zgloba koristeći kompjutoriziranu tomografiju konusnim snopom. Istraživanje je uključilo 45 odraslih ispitanika (32 žene i 13 muškaraca). Inklinacija zglobne kvržice, širina zglobne jamice, dubina zglobne jamice, širina kondila, dužina kondila i tip kondila su utvrđeni za svaki temporomandibularni zglob. S obzirom da t-test za neovisne uzorke nije potvrdio razlike lijeve i desne strane kod svih ispitivanih parametara (α=0,05), vrijednosti lijeve i desne strane su tretirane kao jedan uzorak. Utvrđene su vrijednosti za dubinu zglobne jamice od 7,11±2,23 mm, širinu zglobne jamice 19,22±2,58 mm, širinu kondila 7,54±1,59 mm, dužinu kondila 17,95±2,81 mm i inklinaciju stražnjeg zida zglobne kvržice od 34,59±7,35 stupnjeva. Većina kondila su svrstani pod konveksni tip (32,5%), a slijedili su zaravnani (23,8%), zaobljeni (11,3%) i kutni tip kondila (10%). Pod nedefinirane (neki drugi tip) je svrstano 22.5% kondila. Kompjutorizirana tomografija struktura temporomandibularnog zgloba ove studije je utvrdila sličnosti s većinom prijašnjih istraživanja (u različitim proučavanim populacijama). Ipak, prevalencija različitih tipova kondila se razlikuje od onih u većini istraživanja. Interindividualne razlike u morfologiji temporomandibularnog zgloba su očekivane.

Aneurysmal bone cyst of the cervical spine [Elektronička građa] : case report / Irina Bagić, Marko Kovačević, Vjenceslav Vrtarić, Gordan Reljac, Dario Mužević. - Ilustr.
Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - Aneurysmal bone cyst (ABC) is a non-neoplastic locally destructive primary bone lesion mostly occurring within the first two decades of life with female predominance. Cervical spine ABCs are a very rare clinical entity with particularly demanding surgical resection limited by the involvement of nearby neurovascular structures and a risk for cervical spine instability. We present a case of a 17-year-old patient with a symptomatic ABC of the cervical spine who underwent surgical removal of the osseous lesion with good postoperative outcome. There are different therapeutic strategies for ABC management, but complete surgical removal of the cyst remains one of the most important predictors of favorable outcome, although it can be often limited, especially in the cervical region. Previously described lesions have a very high recurrence rate and therefore different additional methods, such as radiotherapy, embolization and sclerosation have been used in addition to surgical resection. Further studies are necessary for development of evidence-based treatment regimens for cervical spine ABCs in pediatric population. - Aneurizmatska koštana cista je ne-neoplastična, lokalno destruktivna primarna koštana lezija koja se najčešće javlja u prva dva desetljeća života pretežno zahvaćajući ženski spol. Aneurizmatske koštane ciste cervikalne kralješnice predstavljaju vrlo rijedak klinički entitet koji zahtijeva detaljnu kiruršku resekciju većim dijelom limitiranu okolnim neurovaskularnim strukturama i potencijalnim razvojem instabiliteta cervikalne kralješnice. Predstavljamo slučaj 17-godišnjeg bolesnika sa simptomatskom aneurizmatskom koštanom cistom cervikalne kralješnice kojemu je kirurški uklonjena koštana lezija uz zadovoljavajući poslijeoperacijski ishod. Postoje različite terapijske opcije za liječenje aneurizmatskih koštanih cisti, ali potpuna kirurška resekcija ostaje jedan od najvažnijih prognostičkih čimbenika povoljnog ishoda, iako često ograničena, posebno u cervikalnom području. Prethodno opisane lezije imaju vrlo visoku stopu recidiva te se uz kirurško liječenje, kao dodatne terapijske metode, primjenjuju i radioterapija, embolizacija i sklerozacija. Daljnja su istraživanja nužna za razvoj znanstveno utemeljenih terapijskih protokola za liječenje aneurizmatskih koštanih cisti u pedijatrijskoj populaciji.

Application of the Abbey pain scale for assessment of acute perioperative pain in elderly patients with impaired communication following a femur fracture [Elektronička građa] / Marica Jerleković, Marina Domijan, Saša Bareta, Luka Djulabić, Vlatko Mičković, Zoran Lončar. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - Pain resulting from physical trauma and surgical procedures is very strong. In elderly patients, especially those with impaired communication or cognitive damage, it is assessed rarely or not at all. The importance of pain assessment is reflected in quality supervision and adequate treatment which decrease complications and speed up recovery. The aim of the study was to determine the metric characteristics (reliability and validity) of the Abbey Pain Scale on a population of elderly patients with impaired communication in Croatia and to demonstrate the correlation between the assessed acute pain level and analgesia efficacy. The sample consisted of 31 patients above the age of 65 hospitalized after a femur fracture at the Department of Traumatology, Sestre Milosrdnice University hospital, Zagreb, Croatia. The Abbey Pain Scale and Visual Analogue Scale were used for pain assessment. The patients’ mental status was evaluated using Mini-Mental State Examination. The data was processed using Chi-squared and Cronbach’s alpha tests, and small dependent samples were tested using T-test. The value of Cronbach’s alpha coefficient of 0.561 for the Abbey Pain Scale was considered acceptable. The score on the Abbey Pain Scale correlates significantly with the result of a standardized self-assessment of pain intensity (r = 0.739, p= 0.001). We conclude that the Abbey Pain Scale serves as a convenient tool for assessing pain intensity in patients with impaired communication, and its use is indirectly related to satisfactory analgesia, due to good metric characteristics of validity and reliability. - Bol koji proizlazi iz fizičke traume i kirurških zahvata je vrlo jak. U starijih bolesnika, osobito onih s oštećenom komunikacijskim ili kognitivnim oštećenjem, ovaj bol se rijetko ili nikada procjenjuje. Važnost procjene bola ogleda se u kvalitetnom nadzoru i adekvatnom liječenju koji smanjuju komplikacije i ubrzavaju oporavak. Cilj studije bio je utvrditi metrijske karakteristike (pouzdanost i valjanost) bola na populaciji starijih bolesnika sa smetnjama u komunikaciji u Hrvatskoj i pokazati povezanost između procijenjene razine akutnog bola i učinkovitosti analgezije. Uzorak se sastojao od 31 pacijenta starijeg od 65 godina hospitaliziranog nakon frakture butne kosti na Odjelu za traumatologiju Sveučilišta Sestre Milosrdnice u Zagrebu, Hrvatska. Za procjenu bola korišteni su Abbey skala bola i vizualna analogna ljestvica. Duševni status pacijenata ocijenjen je korištenjem ljestvice Mini-mentalnog stanja. Podaci su obrađeni koristeći Chi-kvadrat i Cronbachov alfa test, a mali ovisni uzorci testirani su pomoću T-testa. Vrijednost Cronbachovog alfa koeficijenta od 0,561 za Abbey ljestvicu smatra se prihvatljivom. Ocjena na ljestvici bola značajna je u korelaciji s rezultatom standardizirane samoprocjene intenziteta boli (r = 0,739, p = 0,001). Zaključujemo da Abbey skala bola služi kao prikladan alat za procjenu intenziteta bola u bolesnika s oštećenom komunikacijom, a njezina uporaba neizravno je povezana s zadovoljavajućom analgezijom zbog dobrih metričkih karakteristika valjanosti i pouzdanosti.

Inflammatory and angiogenic biomarkers in diabetic retinopathy [Elektronička građa] / Snježana Kaštelan, Ivana Orešković, Filip Bišćan, Helena Kaštelan, Antonela Gverović Antunica. - Graf. prikazi.
Bibliografija: 100 jed. - Summary. - Diabetic retinopathy (DR) is one of the most common microvascular complications of diabetes mellitus (DM) and a leading cause of blindness in working-age adults in developed countries. Numerous investigations have recognised inflammation and angiogenesis as important factors in the development of this complication of diabetes. Current methods of DR treatment are predominantly used at advanced stages of the disease and could be associated with serious side effects. Therefore, new diagnostic methods are needed in order to identify the initial stages of DR as well as monitoring the effects of applied therapy. Biochemical biomarkers are molecules found in blood or other biological fluid and tissue that indicate the existence of an abnormal condition or disease. They could be a valuable tool in detecting early stages of DR, identifying patients most susceptible to retinopathy progression and monitoring treatment outcomes. Biomarkers related to DR can be measured in the blood, retina, vitreous, aqueous humour and recently in tears. As the retina represents a small part of total body mass, a circulating biomarker for DR needs to be highly specific. Local biomarkers are more reliable as indicators of the retinal pathology; however, obtaining a sample of aqueous humour, vitreous or retina is an invasive procedure with potential serious complications. As a non-invasive novel method, tear analysis offers a promising direction in further research for DR biomarker detection. The aim of this paper is to review systemic and local inflammatory and angiogenic biomarkers relevant to this sight threatening diabetic complication.

Prognostic significance of alkaline phosphatase activity and callus volume in operatively treated bone fractures [Elektronička građa] / Ante Muljačić, Renata Poljak-Guberina, Ognjen Živković, Marko Guberina, Matea Majstorović-Matejić. - Ilustr.
Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - Total and bone alkaline phosphatase are indicators of bone formation, a process essential in bone healing. The aim of this study was to assess the relationship of both total and bone alkaline phosphatase with the course and features of healing in surgically treated long bone fractures as compared to the callus volume. In this study, total and bone alkaline phosphatase levels and the callus volume were measured in two patients with long bone fractures. Fracture healing was rapid in one patient and slow in the other. Depending on the healing outcome, on day 7 an increase in the case of slow healing and a decrease in the case of rapid healing was noted for both total and bone alkaline phosphatase. In the case of slow healing, the callus volume was significant whereas in the case of rapid healing the callus was almost invisible on day 7. This result indicates a possible prognostic significance of aforementioned clinical biochemical and radiographic parameters in the monitoring of long bone fracture healing. - Aktivnosti ukupne i koštane alkalne fosfataze povezane su s procesima izgradnje kosti, nužnih kod cijeljenja prijeloma. Svrha našeg istraživanja bila je ispitati povezanost ukupne i koštane alkalne fosfataze s tijekom i osobitostima cijeljenja kirurški zbrinutih prijeloma dugih kostiju u korelaciji sa volumenom stvorenog kalusa. U ovom istraživanju aktivnost ukupnog i koštanog izoenzima i količina stvorenog kalusa određivana je kod dvaju pacijenata s prijelomom dugih kostiju. Jednog ispitanika karakterizira brzo cijeljenje koštanog prijeloma, a drugog sporo cijeljenje koštanog prijeloma. Rezultati ovog istraživanja pokazali su da je ovisno o ishodu, već 7-og dana došlo do porasta vrijednosti aktivnosti ukupne i koštane alkalne fosfataze kod sporog, odnosno do opadanja kod brzog koštanog cijeljenja. Također kod sporog cijeljenja vidljiv je značajan kalus, dok kod brzog cijeljenja 7-og dana kalus je bio gotovo nevidljiv. Ovaj rezultat ukazuje na moguću prognostičku vrijednost navedenih kliničkih biokemijskih i rendgenskih parametra u praćenju uspješnosti kirurškog cijeljenja prijeloma dugih kostiju.

Telemedicine for diabetic retinopathy screening in Croatia [Elektronička građa] : a dream that could become a reality / Martina Tomić, Petar Raštegorac, Romano Vrabec, Tamara Poljičanin, Dario Rahelić. - Ilustr.
Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - Diabetic retinopathy (DR) is the leading cause of preventable blindness in working-age adults associated with devastating personal and socioeconomic consequences. The increasing use of anti-vascular endothelial growth factor (anti-VEGF) agents over the past decade and telemedicine implementation in systematic DR screening resulted in a decliningtrend of new blindness due to diabetes in several countries. Telemedicine is the remote delivery of healthcare services over the telecommunications infrastructure. It allows healthcare providers to evaluate, diagnose, and treat patients without the need for an in-person visit. Teleophthalmology is a telemedicine branch, mostly focused on diabetic retinopathy and retinopathy of prematurity. Screening for DR in Croatia is commonly performed annually, only by ophthalmologists using dilated slit-lamp biomicroscopic fundus examination. Due to the insufficient number of ophthalmologists and the lack of a formal call system, many diabetic patients do not perform annual screening. In an ideal DR screening model in Croatia, each diabetes center in university or general hospitals throughout Croatia (17 centers) would have one small digital fundus camera and an educated nurse who would perform dilated fundus photography. Electronic images from diabetes centers would be transferred for remote grading to the same hospitals’ ophthalmology departments or a central grading center for DR screening in Croatia. Grading for DR would be performed by an ophthalmologist, medical retina specialist. Patients would be annually invited by mail from the National Diabetes Registry to come to the nearest diabetes center for a fundus photographing and DR screening. Each patient with a positive result would be promptly referred to the medical retina specialist at the closest ophthalmology department for further examination and treatment. - Dijabetička retinopatija (DR) vodeći je uzrok preventabilne sljepoće radno-aktivnih osoba povezan s razornim osobnim i socioekonomskim posljedicama. Sve veća primjena anti-VEGF lijekova u zadnjem desetljeću i uvođenje telemedicine u sustavni probir DR-a rezultirali su smanjenjem novonastale sljepoće zbog dijabetesa u nekim državama. Telemedicina je pružanje zdravstvenih usluga na daljinu putem telekomunikacijske infrastrukture. Pružateljima zdravstvenih usluga time je omogućeno postavljenje dijagnoze i liječenje bolesnika bez potrebe za osobnom posjetom. Teleoftalmologija je grana telemedicine uglavnom usmjerena na dijabetičku retinopatiju i retinopatiju nedonoščadi. Probir DR-a u Hrvatskoj provode samo oftalmolozi, obično jednom godišnje, pregledom očne pozadine nekontaktnim lećama na biomikroskopu. Zbog nedovoljnog broja oftalmologa i nepostojanja formalnog sustava poziva, mnogi bolesnici sa šećernom bolešću ne provode godišnje očne preglede. U idealnom modelu probira DR-a u Hrvatskoj, svaki centar za dijabetes u sveučilišnim ili općim bolnicama diljem Hrvatske (17 centara) imao bi jednu malu digitalnu fundus kameru i educiranu medicinsku sestru koja bi izvodila slikanje očne pozadine u midrijazi. Slike iz centara za dijabetes elektronski bi se prenosile na očitavanje u oftalmološke odjele istih bolnica ili u središnji centar očitavanja i probira DR u Hrvatskoj. Očitavanje slika i stupnjevanje DR-a izvodio bi oftalmolog, subspecijalist za stražnji segment oka. Bolesnici bi jednom godišnje poštom bili pozivali iz Nacionalnog registra za dijabetes da dođu u najbliži centar za dijabetes radi probira DR-a slikanjem očne pozadine. Svaki bolesnik s pozitivnim nalazom bio bi odmah upućen subspecijalistu za stražnji segment oka najbližeg oftalmološkog odjela na daljnju dijagnostičku obradu i liječenje.

Comparison of the neonatal outcome in mothers with gestational diabetes (GD) in two periods [Elektronička građa] / Ella Đukić, Diana Milas, Andrea Prutki, Tihana Nađ, Marijana Arambašić, Vesna Milas. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - Gestational diabetes is one of the most common metabolic complications during pregnancy. Pregnant diabetic mothers, if not well regulated, are more often subject to a number of acute conditions and complications during pregnancy and childbirth. Hypoglycemia, hypocalcemia, hypertrophy, lower Apgar is often seen in children. This is a case control study. We compared mothers with GD and their infants to mothers without GD and their children both in 2015 and 2018 in order to determine whether there are any differences among them, and to compare the perinatal outcome of their infants. Examinees have been born in 2015 and 2018 (262) at KBC Osijek. The control group (262) was first neonates born after the examinees in 2015 and 2018. The results are shown in tables, with absolute and relative frequencies, and the significance of differences in the chi-square test with confidence interval at 95 %. Statistical significance will be accepted at p <0.05 level. Different acute conditions and other chronic illnesses are more common in mothers with GD. They have more complications during labor. Their infants are more often diagnosed with hypertrophy, hypoglycemia, and hypocalcemia. They also require more oxygen tratment, longer hospitalization and birth by C-section. In 2018, the number of hypoglycemic and hypocalcemic infants was twice lower, and children have been hospitalized much shorter. Better care for mothers during pregnancy and their glycemic control lead to significantly less complications in their infants and better perinatal outcome of such infants. - Gestacijski dijabetes je jedna od najčešćih metaboličkih komplikacija u trudnoći. Majke su češće podložne raznim akutnim stanjima i kroničnim bolestima i jako je važno da budu pomno praćene i liječene. Kod njihove djece se češće javljaju hipoglikemija, hipokalcemija, hipertrofija, kao niži Apgar score. Istraživanje je studija parova. Uspoređivali smo majke s GD i njihovu novorođenčad s majkama koje ga nisu imale kao i međusobno u dva razdoblja s odmakom od 3 godine. Novorođenčad majki sa dijabetesom 2015. i 2018.godine (262) u KBC Osijek su ispitanici. Kontrolna skupina (262) su prvo živorođeni nakon ispitanika u 2015. i 2018.godini. Rezultati su prikazani u tablicama, apsolutnim i relativnim frekvencijama, a značajnost razlika hi-kvadrat testom s 95-postotnim intervalom pouzdanosti. Statistička značajnost je prihvaćena uz p<0,05. Majke sa GD češće imaju razna akutna stanja kao i druge kronične bolesti. Njihova novorođenčad češće je hipertrofična, hipoglikemična, hipokalcemična u odnosu na kontrolu skupinu. Također češće imaju potrebu za oksigenacijom i duljom hospitalizacijom kao i carskim rezom. Sve je ovo značajno smanjeno u 2018. godini kada su djeca kraće boravila u bolnici.

Designing an integrated model of oil and gas management with a SWOT approach [Elektronička građa] : the case of NIOC / Seyed Emad Hosseini, Amir Naser Akhavan, Mohsen Bahrami. - Graf. prikazi.
Bibliografija: 10 jed. - Abstract. - In the recent years, the growing demand for energy on the one hand and the reduction of conventional hydrocarbon reserves on the other hand have made the proper extraction of oil and gas reserves, i.e. reservoir management issues, more important and hence proper management of these reserves is inevitable. Although renewable energies currently provide the bulk of the world’s energy needs, hydrocarbon fuels remain the main source of energy until 2035.Despite the growing importance of the Integrated Reservoir Management Model (IRMI), as a rational solution to maximize economic production from oil and gas reservoirs, a comprehensive model that can cover all reservoir management modules has not yet been proposed. In this paper, by examining the current condition of reservoir management in one of the subsidiaries of the National Iranian Oil company and analyzing the obtained results, we offer some solutions to improve the condition and finally, we present a comprehensive model for reservoir management in this company.

Designing of a new type air-water cooled photovoltaic collector [Elektronička građa] / Erhan Arslan, Azim Doğuş Tuncer, Meltem Koşan, Mustafa Aktaş, Ekin Can Dolgun. - Ilustr. ; graf. prikazi.
Bibliografija: 29 jed. - Abstract. - The importance of photovoltaic-thermal (PV / T) collector systems in renewable energy technologies is increasing for combined hybrid electrical heat applications. The efficiency of photovoltaic (PV) systems varies between 5-20%. On average, 15% of the solar radiation coming to the PV panel surface is converted to electrical energy and the remainder is lost. In this study, a PV/T collector was designed using two different fluids simultaneously and its efficiency was calculated numerically. PV/T collector systems are specifically designed for agricultural production and their advantages are discussed. In this study, numerical calculations of PV/T collector with a different design have been made. The results were compared with reference to another experimental study. Two different working fluids (air and water) were used in the calculations. The system where air is used as working fluid is called Mode 1 and the system where water is used is called Mode 2. It is aimed to achieve high heat transfer by using water pipes, air ducts and fins placed under PV panels. In this way, it is aimed to produce a more stable hot air and water. In addition, in order to investigate the effect of flow on the yield, different flow rates were calculated. As a result of the theoretical analyses and calculations made in consideration of literature, the total efficiencies of air flow mode (Mode 1) were calculated as 43.2%, 46,2% and 48.7% at 0.0067 kg/s, 0.0072 kg/s and 0.0077 kg/s mass flow rates, respectively. For water flow mode (Mode 2), these values computed as 52.81%, 53.83% and 55.04% at 0.023 kg/s, 0.036 kg/s and 0.054 kg/s mass flow rates, respectively. It was found that PV / T collector efficiency increased with increasing end flow. Designed collector system is preferable in terms of effective use of energy and it can be easily applicable in processes such as hot air-water preparation, drying and greenhouse heating.

Bibliografija: 12 jed. - Abstract. - In this study, energy and exergy analysis of experimental results obtained from a dehumidification system using LiBr-aq (lithium bromide-water) and LiCl-aq (lithium chloridewater) as desiccant was made. In dehumidifier and regenerator columns polycarbonate sheets, which have not been used before, were used as packing material to increase contact area in purposed liquid desiccant dehumidification system. In the analysis, variation of electrical coefficient of performance and exergy efficiency with airflow rate for different solution mass flow rates were investigated. Because of investigation, maximum values of electrical coefficient of performance and exergy efficiency were calculated approximately as 2.8 and 18%, respectively.

Application of a cold spray based 3D printing process in the production of EDM electrodes [Elektronička građa] / Štefanija Klarić, Zlatko Botak, Damien J. Hill, Matthew Harbidge, Rebecca Murray. - Ilustr., graf. prikazi.
Bibliografija: 31 jed. - Summary. - Cold spray process principles allow the production of near-net-shape metal parts with a fast layer deposition by using 3D printing techniques via supersonic 3D deposition (SP3D). This innovative additive manufacturing process allows an easy and quick production of copper and aluminium parts with future possibilities to expand materials and alloys. The speed and materials enable the application of this cold spray based 3D printing process for the production of tools. In this paper, Electrical Discharge Machining (EDM) electrodes were fabricated by using SP3D to investigate its application in tool production. Requirements for the materials of electrodes and some existing solutions for the production of EDM electrodes with additive manufacturing methods are described first. The fabrication and experimental results are then presented for 3D printed copper EDM electrodes that were tested by using St 37-2 (DIN 17100) steel as the workpiece.

Bibliografija: 13 jed. - Abstract. - This paper presents an application of the finite volume method to ideal plastic metal flow in extrusion technology. Governing equations for the mass and momentum balance are used in an integral form. Solution domains in the cases considered are discretized with a Cartesian numerical mesh with computational points placed at the center of each control volume. After discretization of the governing equations, the resulting system of nonlinear algebraic equations is solved by an iterative procedure, using a segregated algorithm approach. Resulting stress fields are obtained from the Levy-Mises equations. The experimental results and numerical calculations are in good agreement.

Comparison of power distribution, losses and efficiencies of a steam turbine with and without extractions [Elektronička građa] / Vedran Mrzljak, Sandi Baressi Šegota, Hrvoje Meštrić, Zlatan Car. - Graf. prikazi.
Bibliografija: 61 jed. - Abstract. - The paper presents an analysis of two steam turbine operation regimes - regime with all steam extractions opened (base process) and regime with all steam extractions closed. Closing of all steam extractions significantly increases turbine real developed power for 5215.88 kW and increases turbine energy and exergy losses with simultaneous decrease of turbine energy and exergy efficiencies for more than 2%. First extracted steam mass flow rate has a dominant influence on turbine power losses (in comparison to turbine maximum power when all of steam extractions are closed). Cumulative power losses caused by steam mass flow rate extractions are the highest in the fourth turbine segment and equal to 1687.82 kW.

Development and experimental verification of a generative CAD/FEM model of an external fixation device [Elektronička građa] / Elmedin Mešić, Adil Muminović, Mirsad Čolić, Marin Petrović, Nedim Pervan. - Ilustr.
Bibliografija: 15 jed. - Abstract. - This paper presents the development and experimental verification of a generative CAD/FEM model of an external bone fixation device. The generative CAD model is based on the development of a parameterized skeleton algorithm and sub-algorithms for parametric modeling and positioning of components within a fixator assembly using the CATIA CAD/CAM/CAE system. After a structural analysis performed in the same system, the FEM model was used to follow interfragmentary fracture displacements, axial displacements at the loading site, as well as principal and Von Mises stresses at the fixator connecting rod. The experimental analysis verified the results of the CAD/FEM model from an aspect of axial displacement at the load site using a material testing machine (deviation of 3.9 %) and the principal stresses in the middle of the fixator connecting rod using tensometric measurements (deviation of 3.5 %).The developed model allows a reduction of the scope of preclinical experimental investigations, prediction of the behavior of the fixator during the postoperative fracture treatment period and creation of preconditions for subsequent structural optimization of the external fixator.

Energy loss analysis at the gland seals of a marine turbo-generator steam turbine [Elektronička građa] / Lino Kocijel, Igor Poljak, Vedran Mrzljak, Zlatan Car. - Graf. prikazi.
Bibliografija: 43 jed. - Summary. - The paper presents an analysis of marine Turbo-Generator Steam Turbine (TGST) energy losses at turbine gland seals. The analyzed TGST is one of two identical Turbo-Generator Steam Turbines mounted in the steam propulsion plant of a commercial LNG carrier. Research is based on the TGST measurement data obtained during exploitation at three different loads. The turbine front gland seal is the most important element which defines TGST operating parameters, energy losses and energy efficiencies. The front gland seal should have as many chambers as possible in order to minimize the leaked steam mass flow rate, which will result in a turbine energy losses’ decrease and in an increase in energy efficiency. The steam mass flow rate leakage through the TGST rear gland seal has a low or negligible influence on turbine operating parameters, energy losses and energy efficiencies. The highest turbine energy efficiencies are noted at a high load – on which TGST operation is preferable.

Image artefacts in industrial computed tomography [Elektronička građa] / Amalija Horvatić Novak, Biserka Runje, Zdenka Keran, Marko Orošnjak. - Ilustr.
Bibliografija: 21 jed. - Abstract. - Computed tomography is a method that has been used for many years in medicine and material analysis, and recently it has also been introduced in dimensional measurements. The method has a lot of advantages compared to other 3D measurement methods, with the largest one being the possibility to perform a non-destructive measurement of an object’s inner geometry. However, it is a complex method with a large number of parameters that influence measurement results. Some of these parameters are image artefacts that occur in the scanning and reconstruction process. An artefact is any artificial feature which appears on the CT image, but does not correspond to the physical feature of an object. In order to achieve metrological traceability, it is necessary to eliminate and minimize the influence of image artefacts on measurement results. This paper presents and explains image artefacts in industrial computed tomography as the consequences of different influence parameters in the CT system.

Impact of irregular tooth pitch of circular saw blades on power for wood cross-cutting [Elektronička građa] = Utjecaj promjenjivog koraka zubi kružnih pila na snagu za poprečno rezanje drva / Jozef Krilek, Miroslava Ťavodová, Ján Kováč, Branislav Tichý. - Ilustr.
Bibliografija: 43 jed. - Abstract ; Sažetak. - The article deals with the influence of irregular tooth pitch on energy consumption of cross-cutting wood. In this article, the effect was assessed of feeding velocity and parameters of saw blade on the cutting power Pc of spruce (Picea Abies), pine (Pinus Sylvestris) and beech (Fagus Silvatica) wood during sawing with a guided circular saw. For the research, two types of circular saw blades were used, one of them having irregular tooth pitch. The circular saw blades had sintered carbide inserts with a diameter of D = 350 mm and the same number of teeth. The feed velocities were vf = 4, 8,12 m∙min-1 and revolutions n = 3000 min-1. The results showed that the circular saw blades with irregular tooth pitch have higher energy consumption than the circular saw blades with regular tooth pitch. The highest cutting power Pc was shown in the case of beech. It was also shown that energy consumption is increasing linearly with increasing feed velocity. - U radu se prikazuje istraživanje utjecaja promjenjivog koraka zubi kružnih pila na potrošnju energije pri poprečnom rezanju drva. Analiziran je utjecaj posmične brzine, parametara lista pile i vrste drva na snagu rezanja (Pc). Eksperiment je proveden piljenjem drva smreke (Picea abies), bora (Pinus sylvestris) i bukve (Fagus silvatica) vođenom kružnom pilom. Za istraživanje su rabljena dva lista kružnih pila, od kojih je jedan imao promjenjivi korak zubi. Oba su lista kružnih pila imala oštrice od sinteriranih karbidnih umetaka, promjer lista D = 350 mm i jednak broj zubi. Primijenjene su tri posmične brzine: 4, 8 i 12 m∙min-1, a broj okretaja radnog vratila iznosio je n = 3000 min-1. Rezultati su pokazali da je potrošnja energije kružnih pila s promjenjivim korakom zubi veća od potrošnje energije kružnih pila s jednakim korakom zubi. Najveća snaga rezanja Pc zabilježena je pri piljenju bukve. Uočeno je da se potrošnja energije linearno povećava s povećanjem posmične brzine.

Industrial service engineering [Elektronička građa] : training requirements for systematic service development / Clemens Fischer, Herbert-Michael Richter. - Graf. prikazi.
Bibliografija: 29 jed. - Abstract. - Increasing digitization and rising customer requirements represent an opportunity for companies in the machine- and plant engineering industry. For long-term success, combined packages of product and service must be offered, to gain additional revenues and a unique selling proposition. Basically, the advantages of these bundles are slowly establishing themselves in industrial companies. The problem is, that the development and improvement of these bundles run often unsystematically, without a strategy. In Austria, companies are facing the issue, that they are not able to develop new services, due to a shortage of specially skilled employees. This derives out of a lack of clear definition of educational requirements. In order to identify those gaps, an empirical investigation based on expert interviews was conducted and the current status of training requirements was defined. As a result, future service job profiles and potential trends for education and training in the service area of industrial companies were derived thus machine- and plant engineering companies can innovate their employee education strategy.

In-situ process monitoring in additive manufacturing using statistics and pre-process data [Elektronička građa] / Eva Maria Scheideler, Andrea Huxol. - Ilustr.
Bibliografija: 10 jed. - Abstract. - Long computation times are a major obstacle for the application of in-situ monitoring in additive manufacturing. This paper presents rapid in-situ monitoring, which returns a control value within typical build times. Observing powder bed fusion processes reveals that unsuitable parameter settings influence the appearance of the molten surface and the surrounding powder bed. The presented research approach evaluates the changing appearance of the exposed layers, in combination with the information from the preprocess about the position and geometry of the components in each layer. Grayscale images are captured with the build envelope camera and examined regarding the grayscale distribution in the critical areas surrounding the component boundaries. The grayscale distribution is then used to predict product quality by using standard statistical methods. The combination of the pre-process data and the fast analysis of the grayscale distribution allows promptly calculating a performance indicator for required process intervention and control.

Numerical and experimental study of the impeller of a liquid pump of a truck cooling system and the development of a new open-type impeller [Elektronička građa] / Rishat Salakhov, Andrey Ermakov, Elvira Gabdulkhakova. - Ilustr.
Bibliografija: 22 jed. - Abstract. - Typically, closed-type impellers are more efficient than open-type impellers, but in the manufacture of closed-type impellers, cost of wheels is higher. This paper describes the development of cost-effective and simple impeller wheel for a fluid pump in the truck cooling system. To perform this task, the numerical computations of a standard impeller wheel were carried out, its characteristics were also obtained from a test bench, the standard impeller wheel model was verified. The open-type impeller wheel was developed according to the current dimensions of standard impeller wheel and then analyzed with the numerical computations by the software ANSYS CFX (Academic license) computational fluid dynamics. The developed open-type impeller wheel works very effectively in spite of performance degradation by 5% in comparison to the closed-type impeller wheel. When working as a part of engine, the pump efficiency is 0.552-0.579. The maximum value of the pump efficiency is 0.579, it can be achieved at the highest speed of the pump (4,548 rpm and 655 l/min).

Bibliografija: 9 jed. - Summary. - The determination of tolerances has a huge impact on the price and quality of products. The objective of tolerance analysis is to provide the widest possible tolerance range of parts, without disturbing the functionality of the assembly. Tolerance analysis should be performed during the design process because then there is still the possibility for change. For the purpose of carrying out the analysis, three methods will be used: Worst Case method, Root Sum Square method and Monte Carlo Simulation. Methods are explained through simple examples and applied on the one-way clutch.

A novel coplanar waveguide-fed compact microstrip antenna for future 5G applications [Elektronička građa] / Mustafa Berkan Bicer. - Ilustr.
Bibliografija: 41 jed. - Abstract. - In this study, a coplanar waveguide-fed compact microstrip antenna design for applications operating at higher 5G bands was proposed. The antenna with the compact size of 8 x 12.2 mm2 on FR4 substrate, having the dielectric constant of 4.3 and the height of 1.55 mm, was considered. The dimensions of the radiating patch and ground plane were optimized with the use of artificial cooperative search (ACS) algorithm to provide the desired return loss performance of the designed antenna. The performance analysis was done by using full-wave electromagnetic package programs based on the method of moment (MoM) and the finite integration technique (FIT). The 10 dB bandwidth for return loss results obtained with the use of the computation methods show that the proposed antenna performs well for 5G applications operating in the 24.25 – 27.50 GHz, 26.50 – 29.50 GHz, 27.50 – 28.35 GHz and 37 – 40 GHz frequency bands.

A wearable fall detection system based on LoRa LPWAN technology [Elektronička građa] / Elma Zanaj, Deivis Disha, Susanna Spinsante, Ennio Gambi. - Ilustr.
Bibliografija: 65 jed. - Abstract. - The fall problem affects approximately one third of people aged over 65 years. Falls and fall-related injuries are one of the major causes of morbidity and mortality in the elderly population. Since many years, research activities have been targeted towards the development of technological solutions for the automatic detection and notification of falls. Among them, wearable based systems offer the advantage of being available ideally everywhere and cost-effective in terms of economy and computational burden. However, their use poses different challenges, from acceptability to battery usage. The choice of the communication technology, in particular, plays a fundamental role in the realization of a suitable solution, able to meet the target users’ needs. In this paper, we present a fall detection system, based on a pair of instrumented shoes. They communicate the alarming events to a supervising system through the LoRa LPWAN technology, without the need of a portable gateway. Experimental results demonstrate the effectiveness of the chosen communication technology and fall detection reliability.

Chicken swarm optimization for PTS based PAPR reduction in OFDM systems [Elektronička građa] / Saruti Gupta, Ashish Goel. - Graf. prikazi.
Bibliografija: 25 jed. - Summary. - Partial transmit sequence (PTS) is a well-known PAPR reduction scheme for the OFDM system. One of the major challenge of this scheme is to find an optimal phase vector using exhaustive search over all the allowed phase factor combinations. This leads to increased search complexity which grows exponentially as the number of sub-blocks is increased. In this paper, chicken swarm optimization (CSO) based PTS system is designed that aims to find an optimal solution in less number of average iterations and therefore results in reduced computational complexity of the system. We have proposed two categories of the algorithm: (i) CSO-PTS system without threshold limit on PAPR (ii) CSO-PTS system with threshold limit on PAPR. Both the schemes offer effective trade-offs between the computationalcomplexity and the PAPR reduction capability of the system. Simulation results confirm that our proposed schemes perform well in terms of low computational complexity, lesser number of average iterations and improved PAPR reduction capability of the OFDM signal without any loss in BER performance of the system.

Doppler frequency estimation for a maneuvering target being tracked by passive radar using particle filter [Elektronička građa] / Anas Mahmoud Almanofi, Adnan Malki, Ali Kazem. - Graf. prikazi.
Bibliografija: 31 jed. - Summary. - In this paper, we estimate Doppler frequency of a maneuvering target being tracked by passive radar using two types of particle filter, the first is “Maximum Likelihood Particle Filter” (MLPF) and the second is “Minimum Variance Particle filter” (MVPF). By simulating the passive radar system that has the bistatic geometry “Digital Video Broadcasting-Terrestrial (DVB-T) transmitter / receiver” with these two types, we can estimate the Doppler frequency of the maneuvering target and compare the simulation results for deciding which type gives better performance.

Energy efficiency of a wooden house [Elektronička građa] / Anca Constantin. - Ilustr.
Bibliografija: 12 jed. - Abstract. - An exemplary construction project developed in a commune close to Constanta, Romania, aims to build wooden houses for families with low income. The study focuses on their energy performance, aiming to determine simple technical solutions for the improvement of energy efficiency. The original house is a duplex ground floor building. The energy assessment was performed in accordance with the Romanian methodology for the original house, for the reference one and for a variant of the original house whose ground floor is insulated. The study showed that appropriate insulation of the ground floor which covers 30% of the thermal envelope area results in a heating energy saving of 17%. Furthermore, the original horizontal duplex was compared to its similar vertical version (ground floor and one storey) which is more compact, at the same heated volume and the same heated area. The reference vertical version saves 3% of heating energy.

Frequency domain backoff for continuous beamforming space division multiple access on massive MIMO wireless backhaul systems [Elektronička građa] / Kazuki Maruta. - Ilustr., graf. prikazi.
Bibliografija: 32 jed. - Summary. - This paper newly proposes a frequency domain backoff scheme dedicated to continuous beamforming space division multiple access (CB-SDMA) on massive antenna systems for wireless entrance (MAS-WE). The entrance base station (EBS) has individual base band signal processing units for respective relay stations (RSs) to be accommodated. EBS then continuously applies beamforming weight to transmission/reception signals. CB-SDMA yields virtual point-to-point backhaul link where radio resource control messages and complicated multiuser scheduling are not required. This simplified structure allows RSs to work in a distributed manner. However, one issue remains to be resolved; overloaded multiple access resulting in collision due to its random access nature. The frequency domain backoff mechanism is introduced instead of the time domain one. It can flexibly avoid co-channel interference caused by excessive spatial multiplexing. Computer simulation verifies its superiority in terms of system throughput and packet delay.

Frequency plan optimization based on genetic algorithms for cellular networks [Elektronička građa] / Hicham Megnafi. - Ilustr., graf. prikazi.
Bibliografija: 21 jed. - Summary. - Cellular networks are constantly evolving to ensure a better Quality of Service (QoS) and quality of coverage ever more important. The radio cellular systems are based on frequency allocation. In this context, frequency allocation principle consists in choosing an optimal frequency plan to meet traffic demand constraints and communication quality while minimizing the radio interferences. This paper proposes an optimal frequency allocation approach based on genetic algorithms to minimize co-channel and adjacent channel interference. The validation of this new approach is confirmed by the results of the work we have done in the GSM network. In fact, we used the file obtained by the OMC-R, which defines the adjacent cells of each cell and the frequencies allocated to the considered area. The results obtained clearly show the effectiveness and robustness of the approach used.

Joint RSMA and IDMA-based NOMA system for downlink communication in 5G and beyond networks [Elektronička građa] / Aasheesh Shukla. - Graf. prikazi.
Bibliografija: 15 jed. - Abstract. - Future communication networks may encounter various issues in order to facilitate heavy heterogeneous data traffic and large number of users, therefore more advanced multiple access (MA) schemes is required to meet the changing requirements. Recently, a promising physical-layer MA technique has been suggested for multi-antenna broadcast channels, namely Rate Splitting Multiple Access (RSMA). This new scheme has the ability to partially decode the interference and partially treat the remaining interference as noise which makes it to cope with wide range of user deployments and network loads. On the other hand, interleave division multiple access (IDMA) has already been recognized as a potential code domain NOMA (non-orthogonal multiple access) scheme, suitable for 5G and beyond communication network. Hence, in this paper, a new approach of multiple access scheme is proposed to get the grip on new challenges in future communication (6G). The proposed framework consists the joint processing of RSMA and IDMA (code domain NOMA), in which the transmitter involves an IDMA as encoder and allows rate splitting to split the message in two parts i.e. common part and private part, before the actual transmission. The mathematical modeling of proposed system is elaborated in the paper and for simulation purpose the downlink communication scenario has been considered where users faced diverse channel conditions. The weighted sum rate (WSR) performance is evaluated for the proposed scheme which validate the quality of service (QoS) of the joint RS-IDMA system.

Monopoly-market-based cooperation in cognitive radio networks [Elektronička građa] / Said Lakhal, Zouhair Guennoun. - Ilustr., graf. prikazi.
Bibliografija: 22 jed. - Summary. - In a cognitive radio network (CRN), the primary users (PUs) do not operate their spectra, full time. Thus, they can sell them to the secondary users (SUs), for a second use, during the free time slots. In this article, we assume that the market is perfect, monopolized by a single PU, and all players are rational. After formulating the PU’s profit, we established a necessary and sufficient condition that guarantees the introduction of the PU into the market. In addition, the expressions of the SUs’ profits, showed us that in non-cooperative form, some ones got zero profit, even after maximizing their profits. Therefore, we have considered to study the effect of cooperation on the profits of this category of SUs. By following this step, we established a cooperation strategy, to avoid zero profits for all SUs. In order to analyze the impact of this cooperation on the PU, we have expressed the profits of the PU in the cooperative and non-cooperative forms; as result, we found that the cooperation between SUs brought better than the non-cooperative form.

Novel m-PSO-SVM based interface controller design for haptic system [Elektronička građa] / Naveen Kumar, Jyoti Ohri. - Ilustr., graf. prikazi.
Bibliografija: 35 jed. - Summary. - The haptic system has two key performance issues: stability and transparency. A haptic interface controller (HIC) is designed to address these issues. Addressing these issues becomes a complex problem as both are complementary to each other. Here, when transparency of the system is increased, its stability degrades and vice-versa. To overcome this problem, intelligent optimized solutions are used in this paper to design a HIC controller for the haptic system. SVM and NN techniques have been employed to identify the performance of the controller, ensuring stability and transparency both. The disadvantages of NN in terms of the number of neurons and hidden layers are overcome by SVM. Further, the performance of SVM is highly dependent upon the selection of free parameters. So, further, a modified PSO technique is employed for the optimal selection of these parameters to enhance the performance of SVM. Hence, this novel proposed hybrid technique of m-PSO optimized SVM is applied for the optimal design of the HIC to find out an optimal solution between trade-off the transparency and stability of the haptic device simultaneously. To appreciate the efficacy of the proposed technique, the result obtained with this is compared with HIC design using neural network and conventional ZN method also. This designed controller ensures stability as well as transparency, even under the presence of uncertainty, delay, and quantization error.

Performance of a new design based on substrate-integrated waveguide slotted antenna arrays for dual-band applications (Ku / K) [Elektronička građa] / Turkiya Abes, Keltouma Nouri, Boubaker Seddik Bouazza, Kada Becharef. - Ilustr., graf. prikazi.
Bibliografija: 30 jed. - Summary. - This paper introduces and discusses the study of a new concept for SIW array antenna development. This conducted development is based on three designs, two of them related to 1x2 arrays fed by SIW line, combined with SIW inset line, and the last designed for 2X2 array antenna feed by SIW inset line. All these structures are designed to give dual-band at (Ku - K) bands with enhanced gain and bandwidth. The new 2x2 array antenna has a high gain, and it consists of four SIW cavities staggered patches with a 90° phase shift, which are fed using microstrip line shielded by SIW vias. The designs were conducted using full-wave simulator ANSYS HFSS - the frequency domain solver. The 2x2 array antenna gives a return loss about (-20 dB), a high gain of 9.05 dB, and two bandwidth equals 210 MHz and 1310 MHz respectively at both of the operating bands. To validate the simulated results the simulation was conducted again using the time-domain solver of the CST Microwave Studio (MWS) full-wave simulator. Simulation results obtained from the two software having different solvers were in good agreement in the results.

Performance of the product of three Nakagami-m random variables [Elektronička građa] / Dragana Krstic, Petar B. Nikolic, Ivan Vulic, Sinisa Minic, Mihajlo C. Stefanovic. - Graf. prikazi.
Bibliografija: 28 jed. - Summary. - An output signal from a multi-section wireless relay communication system is equal to the product of the signal envelopes from individual sections. In this paper, a three-sections relay system is considered in the presence of Nakagami-m fading at each section. First, random variable (RV) is formed as the product of three Nakagami-m RVs. For such product, the moments are determined in the closed forms. The first moment is the mean of the signal; the second moment is the average power of the signal, and the third moment is skewness. Then, the Amount of Fading (AoF) is calculated. AoF is a measure of the severity effect of fading in a particular channel model. Besides, all system performance are shown graphically and the parameters influence has been analyzed and discussed.

Placement and quantitating of FACTS devices in a power system including the wind unit to enhance system parameters [Elektronička građa] / Amir Bagheran Sharbaf, Ali Asghar Shojaei. - Graf. prikazi.
Bibliografija: 19 jed. - Abstract. - One of the main concerns of network operators is the enhancement of system parameters; accordingly, a set of different means to this end are posed. However, the use of renewable energies such as the wind could increase the importance of the debate over sustainability and conditions of power system parameters. In this study, the condition of said parameters is examined by placing FACTS (Flexible Alternating Current Transmission System) devices in a 24-bus power system including a wind farm. Research data entailing information on the wind and the amount of consumption load per year are classified by using the K-means classification algorithm; then, the objective function is obtained according to the parameters intended for optimization. This function is optimized by using the Honey-bee mating optimization (HBMO) algorithm followed by obtaining the suitable place and amount for FACTS devices. The results showed that the examined parameters are optimized when using FACTS devices.

Poduzeća SUFID i La Dalmatienne od osnutka do Drugoga svjetskog rata [Elektronička građa] : crtice iz povijesti elektrifikacije Šibenika i okolice / Tomislav Anić.
Bibliografske bilješke uz tekst ; bibliografija i izvori: str. 456-458. - Sažetak ; Summary. - U članku se istražuju okolnosti osnivanja i rad poduzeća SUFID i La Dalmatienne. Poseban naglasak stavljen je na aspekt elektrifikacije Šibenika i njegove okolice s obzirom na ulogu tih pravnih subjekata. Prateći razvoj poduzeća u gotovo polustoljetnom razdoblju od kraja XIX. do prve polovine XX. stoljeća, težište je stavljeno na prepoznavanje važnijih elemenata procesa modernizacije koji su bili izravna posljedica druge industrijske revolucije. Poduzeća su u tom razdoblju bila podložna svim promjenama s obzirom na ekonomske i političke okolnosti. - The history of large industrial companies in the late 19th and first half of the 20th century mirrors the modernity of every society. The goal of this paper is to explore the history of the companies ‘SUFID’ and ‘La Dalmatienne’ in light of those economic and political developments that influenced their work. Based on archival research conducted in the Croatian State Archives and the State Archives in Šibenik, the work of the ‘SUFID’ and ‘La Dalmatienne’ factories in regard to the development of electrification and its consequences are analysed. The focus of study is the production of electrical energy, which made up a significant part of the total production of both companies and greatly changed the life of Šibenik and its surrounding area. Through case studies on the development of the ‘SUFID’ and ‘La Dalmatienne’ companies, some of the more important elements of the functioning of the economy are explained, such as the influence of global economic trends on local economic developments and the influence of international politics on domestic politics, which had a direct impact on the functioning of the economy and the regulation of property-law relations. The consequences of industrialisation, i.e. its direct influence on the immediate surroundings, are also analysed. From the time of early industrialisation, property-law relations were encroached upon, as was the manner of their resolution, in order to pave the way for changes in space needed for the development of infrastructure, especially roads and power transmission line routes.

Recent results on the implementation of a burst error and burst erasure channel emulator using an FPGA architecture [Elektronička građa] / Caterina Travan, Francesca Vatta, Fulvio Babich. - Ilustr.
Bibliografija: 60 jed. - Abstract. - The behaviour of a transmission channel may be simulated using the performance abilities of current generation multiprocessing hardware, namely, a multicore Central Processing Unit (CPU), a general purpose Graphics Processing Unit (GPU), or a Field Programmable Gate Array (FPGA). These were investigated by Cullinan et al. in a recent paper (published in 2012) where these three devices capabilities were compared to determine which device would be best suited towards which specific task. In particular, it was shown that, for the application which is objective of our work (i.e., for a transmission channel simulation), the FPGA is 26.67 times faster than the GPU and 10.76 times faster than the CPU. Motivated by these results, in this paper we propose and present a direct hardware emulation. In particular, a Cyclone II FPGA architecture is implemented to simulate a burst error channel behaviour, in which errors are clustered together, and a burst erasure channel behaviour, in which the erasures are clustered together. The results presented in the paper are valid for any FPGA architecture that may be considered for this scope.

Reference breast phantoms for low-cost microwave imaging [Elektronička građa] / Emine Avşar Aydin, Selin Yabaci Karaoğlan. - Ilustr.
Bibliografija: 22 jed. - Abstract. - Microwave imaging provides an alternative method for breast cancer screening and the diagnosis of cerebrovascular accidents. Before a surgical operation, the performance of microwave imaging systems should be evaluated on anatomically detailed anthropomorphic phantoms. This paper puts forward the advances in the development of breast phantoms based on 3D printing structures filled with liquid solutions that mimic biological tissues in terms of complex permittivity in a wide microwave frequency band. In this paper; four different experimental scenarios were created, and measurements were performed, and although there are many vector network analyzers on the market, the miniVNA used in this study has been shown to have potential in many biomedical applications such as portable computer-based breast cancer detection studies. We especially investigated the reproducibility of a particular mixture and the ability of some mixes to mimic various breast tissues. Afterwards, the images similar to the experimentally created scenarios were obtained by implementing the inverse radon transform to the obtained data.

Target coordinates estimation by passive radar with a single non-cooperative transmitter and a single receiver [Elektronička građa] / Ali Kazem, Adnan Malki, Anas Mahmoud Almanofi. - Graf. prikazi.
Bibliografija: 43 jed. - Summary. - Passive radar is a bistatic radar that detects and tracks targets by processing reflections from non-cooperative transmitters. Due to the bistatic geometry for this radar, a target can be localized in Cartesian coordinates by using one of the following bistatic geometries: multiple non-cooperative transmitters and a single receiver, or a single non-cooperative transmitter and multiple receivers, whereas the diversity of receivers or non-cooperative transmitters leads to extra signal processing and a ghost target phenomenon. To mitigate these two disadvantages, we present a new method to estimate Cartesian coordinates of a target by a passive radar system with a single non-cooperative transmitter and a single receiver. This method depends on the ability of the radar receiver to analyze a signal-to-noise ratio (SNR) and estimate two arrival angles for the target’s echo signal. The proposed passive radar system is simulated with a Digital Video Broadcasting-Terrestrial (DVB-T) transmitter, and the simulation results show the efficiency of this system compared with results of other researches.

THD analysis of a seven, nine, and eleven level cascaded H-Bridge multilevel inverter for different loads [Elektronička građa] / Manoj Kumar Sahu, Madhusmita Biswal, Jagan Mohana Rao Malla. - Graf. prikazi.
Bibliografija: 78 jed. - Summary. - A multilevel inverter is implemented for generating the required staircase AC voltage of output from various steps of voltages of DC sources. The multilevel inverter gives a better harmonic spectrum and a compatible quality of output. This article delves into an analytical analysis of the total harmonic distortion (THD) of different multilevel inverters which employ a multicarrier PWM technique. This technique is implemented for operating the switches at their respective angle of conduction. This paper deals with various cascaded H-Bridge multilevel inverters (CMI) with various loads that are modelled by implementing the MATLAB/Simulink platform. The output gives a better result of the proposed model in terms that it is helpful towards reducing the THD and the losses of switching.

Undesired radiation suppression technique with adaptive control for distributed array antenna systems in mobile environment [Elektronička građa] / Hideya So, Kouhei Suzaki, Daisuke Goto. - Ilustr.
Bibliografija: 12 jed. - Abstract. - We have proposed a distributed array antenna (DAA) system for high-speed satellite communications. The DAA system uses multiple small tracking antennas and combines the transmission signals in-phase to increase the antenna gain. DAA system has a problem that the undesired radiation at the sidelobe direction increases as the antenna gain at the main lobe direction increases. In the mobile environment, the conventional technique can suppress the undesired radiation in the limited condition because of changing the direction of the undesired radiation according to the movement of the mobile station. This paper proposes a DAA technique that suppresses the undesired radiation by setting a transmission plate at each antenna aperture and moving them via adaptive control. The transmission plate consisting of a metal patch or slot retransmits electromagnetic waves and changes the amplitude and phase of the waves. To change the radiation patters of each antenna, the transmission plate rotates according to movement of the mobile station. After combining these changed signals, the adaptive control selects the rotate angle of the transmission plate to decrease the undesired radiation at the sidelobe direction. The antenna gain on the main lobe direction after combining is achieved with lower loss because the insertion loss through the transmission plate is smaller. The proposed technique offers more than $2.4$ dB improvement with three antennas and more than $3.5$ dB improvement with four antennas assuming each consists of $8 ¥times 8$ patches.

Stabilizacija krhotina razrušenih stijena zagađenih otpadnom isplakom [Elektronička građa] / Slavica Marinović, Tamara Troskot Čorbić, Tihana Goričnik, Nada Uzorinac Nasipak, Vedrana Čizmek. - Ilustr., graf. prikazi.
Bibliografija: 12 jed. - Sažetak ; Summary. - U hrvatskoj naftnoj industriji godišnje se proizvodi značajna količina krhotina razrušenih stijena. Krhotine razrušenih stijena zagađene su otpadnom isplakom te spadaju u heterogeni otpad koji sadrži ugljikovodike, teške metale i kloride. Trenutačno se kao metoda zbrinjavanja krhotina primjenjuje metoda stabilizacije uz pomoć vapna i pijeska. Opisan je postupak pripreme stabiliziranog otpada u laboratorijskim uvjetima na dva uzorka krhotina iz isplačnih jama s područja Dravske depresije. Prije pripreme stabiliziranog otpada u laboratorijskim uvjetima, u početnom uzorku otpada određen je udio organske tvari dobiven ekstrakcijom s organskim otapalom te sadržaj ukupno topljive tvari u vodi. Na temelju te dvije osnovne analize određena je količina vapna i pijeska potrebna za izradu stabiliziranog otpada. Fizikalno-kemijske značajke početnog i stabiliziranog otpada analizirane su primjenom standardnih laboratorijskih metoda. Rezultati su pokazali da miješanje otpada s vapnom i pijeskom omogućuje prevođenje početnog uzorka otpada klasificiranog kao opasan otpad u neopasan otpad. - In the Croatian oil and gas industry, significant quantities of drill cuttings are produced annually. The drill cuttings are contaminated with waste mud being heterogeneous waste which comprises hydrocarbons, heavy metals and chlorides. Currently, the treatment option for these drill cuttings is stabilization method using lime and sand as binder. The procedure of stabilized waste preparation in laboratory conditions on two samples of drill cuttings from Drava Depression is described. Prior to the stabilization test under laboratory conditions, it was necessary to determine the content of organic matter in the initial waste sample using organic solvent extraction method, and the content of total soluble matter in water. On the basis of these two parameters, the amount of lime and sand required to produce stabilized waste were determined. Initial and stabilized waste samples were analysed according to standard methods. The results indicated that the process of stabilization of waste using lime and sand enabled the transformation of an initial waste sample classified as hazardous waste into non-hazardous waste.

Analysis of methods for determining climate loads at a specified territory point by meteorological data [Elektronička građa] / Željko Kos, Viktor Pashynskyi, Yevhenii Klymenko, Mykola Pashynskyi. - Graf. prikazi.
Bibliografija: 12 jed. - Summary. - Methods for determining the characteristic values of climate loads at the location of a building have been perfected. Based on comparative analysis, the method of levelling the values of climate loads with an exponential or triangular weight function is recommended. For four climate loads, appropriate equalization intervals are determined, ensuring the maximum amount of weather data taken into account, while maintaining their uniformity. In construction, the determination of the climate load is important for the location of the building. When prescribing building standards, the values of the climate load are determined according to the data of weather stations in relative proximity, which provides values within the limits of reliability. Such an approach can lead to an overestimation of the characteristic values of climate loads and consequently increase the consumption of the construction materials of the building or, in the opposite case, decrease the unnecessarily high-energy consumption to condition the space inside the building.

Dimensional structural mass optimization of a welded I-profile bridge crane girder [Elektronička građa] / Nedim Pervan, Adis J. Muminovic, Elmedin Mesic, Mirsad Colic, Vahidin Hadziabdic. - Ilustr.
Bibliografija: 33 jed. - Abstract. - This paper presents the methodology for the development of an optimization model for the optimization of the cross-section dimensions of a bridge crane girder designed as a welded I-profile. To carry out this optimization, the CAD/CAE software package CATIA V5 was used. In order to develop an optimization model, a CAD geometrical model and structural analysis model were developed. Optimization was carried out by the iterative method using a simulated hardening algorithm. Additionally, the optimization process is carried out by using the PEO (Product Engineering Optimization) CATIA module that contains tools for setting the optimization criteria, design parameters, constraints, and algorithms. The goal of the optimization is to achieve the minimal mass of the girder, while satisfying all functional and geometrical constraints. As a result of the optimization process, minimal girder dimensions were obtained and due to that, a minimal amount of material can be used for the manufacturing of the girder.

Elements of the fourth industrial revolution in the production of wood buildings [Elektronička građa] / Jozef Švajlenka, Mária Kozlovská. - Ilustr.
Bibliografija: 25 jed. - Abstract. - We are on the threshold of a technological revolution that fundamentally changes the way we live, work and communicate with each other. To some extent, scale and complexity, this transformation will be as fundamental to humanity as no other technological change in the past. We do not know how it will evolve, but one thing is clear: the response to it must be integrated and comprehensive, involving all stakeholders on a global basis, from the public to the private sector, to the academic community and to civil society. In the context of sustainable and efficient construction, traditional material bases such as wood are becoming increasingly prevalent and implemented in modern design processes and design solutions. The great potential of this building material is achieved due to developments in production as well as the actual construction of timber buildings. Possible ways of production and construction of wooden buildings are diverse. Especially through prefabricated and solid wood products, which are also cross-glued laminated timber products, modern timber construction represents an interesting and sustainable construction technology. The aim of this paper is to define the basic aspects of industrial building industry in the context of new trends and to introduce the possibilities of implementation of elements of industry 4.0 in the field of wood-based construction.

Investigating the effect of geocell changes on slope stability in unsaturated soil [Elektronička građa] / Behnam Mehdipour, Hamid Hashemolhosseini, Bahram Nadi, Masoud Mirmohamadsadeghi. - Ilustr.
Bibliografija: 31 jed. - Abstract. - The purpose of this research is to investigate the performance and efficiency of reinforced slope in the stability of geocell layers in unsaturated soil conditions. Slope reinforced with geocell acts like a beam in the soil due to the geocell having a height (three-dimensional). Due to its flexural properties, it has moment of inertia as well as bending strength, which reduces the displacement and increases the safety factor of the slope. Taking into consideration unsaturated conditions of soil contributes a lot to making results close to reality. One of the well-known models among elastoplastic models for modeling unsaturated soils is Barcelona Basic Model, which has been added to the FLAC2D software by codification. Changes in thickness, length and number of geocell layers are remarkably effective on slope stability. The results show that the geocell's reinforcing efficiency depends on the number of layers and depth of its placement. As the depth of the geocell's first layer increases, the lateral and vertical side elevation of the upper part of the slope increases with respect to the elevation. Load capacity increases with increasing geocell length. By increasing the length of the geocell layer, the joint strength, the mobilized tensile strength, and the bending moment are increased. At u/H = 0.2, an increase in the bending momentum of about 20% occurs with increasing geocell thickness. In u/H = 1, the increase in bending momentum is 10.4%. In addition, by increasing the thickness of the geocell, the Value of moment of the inertia increases and, as a result, the amount of geocell reinforcement bending moment increases.

Research of the residual bearing capacity and the work of damaged reinforced concrete beams' inclined sections [Elektronička građa] / Zeljko Kos, Yevhenii Klymenko, Kostiantyn Polianskyi, Andjelko Crnoja. - Graf. prikazi.
Bibliografija: 12 jed. - Summary. - The article is devoted to studies about the stress-strain state and the residual bearing capacity of inclined sections of reinforced concrete beams with concrete damages in the compressed zone near support areas. The developed method of calculating the bearing capacity of the inclined sections of damaged beams is described. The numerical test of prototypes was performed in the LIRA-CAD 2017 software complex. A comparison of the results of laboratory tests, a numerical experiment and calculation results by the proposed method is shown. It is stressed that with an increase in the area of damage, the bearing capacity decreases. The nature of the change in the stress-strain state under the presence of damage is described. It is pointed out that in the damaged samples, there is an inclination of the neutral axis in the cross section of the element – it tilts, the neutral axis becomes, almost, parallel to the front of the damage.

Statistical methods in building industry to determine prices indices [Elektronička građa] / Helena Ellingerová, Zora Petráková, Ingrida Skalíková. - Graf. prikazi.
Bibliografija: 24 jed. - Abstract. - Tender price is often affected by the location of the construction, which is usually determined by the investor, and it has an impact on the traffic in the particular location. Individual time of supply and the method of realization play an important role as well. They both are determined by the investor along with the designer of the particular construction. Contractors often complain about the lack of time needed for the preparation of their tender prices. Therefore, it is necessary to look for the possibilities how to reliably speed up this process at the same time taking into account all of the specific features of a structure. This article deals with the application of two statistical methods. The Pareto analysis, which can be used during the design of the tender price, and the extrapolation method, which can be used for the estimation of the price development, based on the regression analysis of the time series. The results of the article particularly serve to contractors in the building industry to better prepare their price offers in tenders. The findings of this document may also be applicable in other countries which have a similar economic profile as Slovakia.

Technical problems of industrial buildings adaptation [Elektronička građa] : case study : "Artist's alley" in Zielona Góra / Beata Nowogońska. - Ilustr.
Bibliografija: 18 jed. - Abstract. - The adaptation of post-industrial building allows for solving problems connected with the protection of relics and is useful in the process of providing order to the cultural landscape. However, the adaptation of historic buildings is associated with many problems. At the same time, the conservation, architectural, construction, technological requirements and the investor's ideas must be met. Meeting all conditions at the same time is a difficult task, but possible. The change in the way that a historic building is used requires a series of preliminary studies of the building to be carried out. The article presents the results of the diagnosis of the technical conditions preceding the adaption of a former factory in Zielona Góra.

Thermal and acoustic insulating gypsum composite material with improved water resistance [Elektronička građa] / Volodimir Yakovich Kersh, Andriy Valeriyovich Kolesnikov, Mikola Volodymyrovich Hlitsov, Sergіi Ivanovich Gedulyan. - Graf. prikazi.
Bibliografija: 15 jed. - Abstract. - The article discusses methods for obtaining building heat and sound insulating composite material based on gypsum with high resistance to water. An additional characteristic is considered - the water resistance index, in which the role of material strength in the wet state is enhanced. The proposed characteristic is used to optimize the heat and sound insulating composition based on gypsum. The material contains matrix gypsum-cement-ash binder and a mixture of aggregates. The result of the planned experiment shows that the water resistance index more adequately reflects the strength of the composite in the wet state compared to the softening coefficient. An optimization of the complex properties of the composite is given in accordance with its intended purpose. As a result of the study, an optimal waterproof composition with improved thermal insulation and sound insulation characteristics was obtained.

UAV, digital processing and vectorization techniques applied to building condition assessment and follow-up [Elektronička građa] / Carles Serrat, Sebastian Banaszek, Anna Cellmer, Vicenç Gilbert, Anna Banaszek. - Ilustr.
Bibliografija: 13 jed. - Abstract. - The aim of the paper is to explain the basic principles of carrying out an inventory and follow-up of buildings and their condition assessment, by using the Full Interactive Visualization Method for Building Condition Assessment platform. It is a platform enabling the implementation of construction inventory based on the remote cooperation of many specialists in the field of, among others: building construction, architecture, civil engineering, photogrammetry, CAD, UAV. This type of cooperation is of particular importance especially in the context of the current epidemiological situation related to COVID-19. The idea of the presented platform fits into the broadly understanding of Building Information Modeling. After introducing the methodology, stages of the inventory and follow-up process carried out within the platform are illustrated and discussed on the basis of a case study. Based on the obtained results it can be concluded that the proposed methodology creates a convenient, efficient and inexpensive tool for massive inspection of building resources in large areas. The inventory is based primarily on high-quality photo and video material obtained from the deck of an unmanned aerial vehicle and the expert knowledge of the inspector conducting the inspection. By combining digital images data (photos, 3D model, orthophotos) with substantive data (facade element classification tables, wear / defect classification tables), we get a platform that allows intuitive access to viewing, classification, editing and analysis of selected data.

The statistical and technical evaluation of the wastewater treatment plants in holiday resorts [Elektronička građa] / Aysegul Pala, Ecem Kocabıyık, Gunes Kursun. - Graf. prikazi.
Bibliografija: 5 jed. - Summary. - The aim of this study is technical and statistical evaluation of wastewater treatment plants existing at the holiday resorts in areas surrounding Izmir City. The study was carried out in the time period from August to September 2018. Within the scope of the study, 150 holiday resorts were investigated and listed. The necessary permissions were obtained and the treatment plants were visited at their current locations. Most of the wastewater treatment plants are embedded in the ground and are referred to as package treatment systems. They are used at holiday resorts for many reasons, such as smell and noise control. Many parameters have been considered within the scope of the study, such as installed power of the plant, influent wastewater flow and pollutant concentration, the properties of the sludge, sludge disposal methods, effluent wastewater parameters, the method and location of effluent water discharge, operation period of the wastewater treatment plant. As a result of this study, it has been found that the low cost package treatment systems were generally preferred. The systems that required most energy were the blowers. In order to provide clean and smooth environment, the use of central wastewater treatment plants is more suitable than the use of package treatment systems.

MANIN, Marino
Svjetionik Savudrija i njegovo mjesto u povijesti pomorstva [Elektronička građa] / Marino Manin. - Ilustr.
Bibliografske bilješke uz tekst ; bibliografija: str. 479-481. - Sažetak ; Riassunto ; Summary. - Rad se zasniva mahom na raščlambi arhivskih vrela iz Državnoga arhiva u Trstu o planovima, izgradnji i puštanju u rad svjetionika u Savudriji u noći sa 17. na 18. travnja 1818. godine. Tijekom prvih godina rada za rasvjetu svjetionika koristio se destilirani plin, koji se dobivao od ugljena iz istarskih ugljenokopa, što je bilo iznimno tehnički inovativno na razini Habsburške Monarhije i svijeta. Uzmemo li u obzir primjenu te vrste postrojenja za rad svjetionika, prema podacima kojima autor trenutačno raspolaže proizlazi da u tom području svjetioniku Savudrija pripada posve zanemareni svjetski primat. Rad donosi nove podatke o plinskome postrojenju i Antonu Domeku, koji ga je izgradio. - Il saggio si basa per lo più sull’analisi delle fonti d’archivio conservate presso l’Archivio di Stato di Trieste e riguardanti i piani, l’edificazione e la messa in funzione del faro di Salvore nella notte tra il 17 e il 18 aprile del 1818. Durante la fase iniziale si usava il gas distillato per allimentare la luce di questo faro, per l’ottenimento del quale si destilava il carbone dalle miniere dell’Arsa, e questo processo era tecnologicamente eccezionalmente innovativo, come per la Monarchia degli Asburgo, così pure al livello mondiale, perché ad esempio a Vienna appena nel 1818 fu messo in funzione un simile sistema per l’illuminazione cittadina, mentre a Londra ciò avvenne nel 1813. Se consideriamo l’applicazione di questo tipo di impianti per il funzionamento dei fari, secondo le conoscenze fino ad ora aquisite dall’autore risulta che a Salvore appartiene un primato completamente dimenticato, dal momento che nella letteratura specializzata si asserisce che il primo faro simile sia stato messo in funzione nel 1865, quando John Richardson Wigham mise in funzione il faro di Baily nei pressi di Dublino. Il fanale del faro di Salvore era alimentato a gas ben 47 anni prima, ma dal momento che in quei tempi gli impianti di distillazione di gas erano nella loro fase d’uso iniziale e che emergevano numerose imperfezioni tecnologiche, ad esempio la produzione eccessiva di fuliggine, perché a quei tempi non esisteva un sistema sofisticato di filtrazione del gas e di separazione dei sottoprodotti, e nonostante il fatto che questo tipo d’illuminazione era meno costoso di quello ad olio, nel 1823 la sostituirono con quella più antiquata e semplice. - This study is mostly based on analysis of archival data from the State Archives in Trieste concerning the planning, construction, and opening of the lighthouse in Savudrija in the night of 17/18 April 1818. In the beginning, the lighthouse used distilled gas to produce its light; it was obtained from coal from the Raša Coal Mines. This process was exceptionally technologically innovative on the level of the Habsburg Monarchy and even the world, since a similar system of public city lighting was introduced in Vienna only in 1818, and in London in 1813. Considering the application of this facility for the functioning of a lighthouse, and according to the data available to the author at this time, it appears that Savudrija achieved a first in this area, which has since been completely forgotten. Namely, according to existing literature, the first lighthouse of this sort began functioning in 1865, when John Richardson Wigham designed a gas illumination system for the Baily lighthouse near Dublin. The gas lamp in the Savudrija lighthouse began to function 47 years earlier. However, since gas distillation facilities were still in their infancy at this time and had numerous technological weaknesses – for example, the lamps were prone to soot due to the lack of a sophisticated gas filtering and by-product separation system – and, despite the fact that this form of illumination was somewhat cheaper than oil-based systems, it was replaced by that older and simpler type of illumination in 1823.

Dubrovački vodovod u XIX. i XX. stoljeću [Elektronička građa] / Irena Ipšić.
Bibliografske bilješke uz tekst ; bibliografija: str. 244-248. - Sažetak ; Summary. - U radu se prati razvoj dubrovačkoga vodovoda tijekom XIX. i XX. stoljeća, čija je okosnica (sve do sredine XX. stoljeća) bio vodoopskrbni gravitacijski sustav izgrađen u XV. stoljeću. Na temelju dosadašnjih saznanja, arhivskih dokumenata, starih novinskih napisa te dokumentacije iz pismohrane današnje gradske tvrtke „Vodovod Dubrovnik” prate se rekonstrukcije i popravci dotrajaloga vodovodnoga kanala i popratnih objekata, izgradnja i održavanje gradskih fontana, provođenje vodoopskrbne infrastrukturne mreže prema privatnim objektima te u konačnici projekt izgradnje cjelovitoga suvremenoga vodoopskrbnog sustava polovinom XX. stoljeća, kojim se i danas vodom napaja gradsko područje. - Based on existing knowledge, archival documents, old newspaper articles, and documentation from the contemporary city company ‘Vodovod Dubrovnik’ (Dubrovnik Waterworks), this paper follows the development of the Dubrovnik waterworks during the 19th and 20th centuries. The backbone of the new waterworks until the mid-20th century was the gravity flow water distribution system built in the 15th century. This was an important project that signified a turning point in socio-economic progress and left a significant mark on the further development of Dubrovnik. Its communal value is also apparent from the fact that a water canal was built at that time and, with several extensions and modifications, continued to provide water to the city area until the mid-20th century, when construction of the contemporary Dubrovnik water supply system began. Due to financial difficulties, repair work was limited to the most critical issues, while the increasing demand for water was met by smaller-scale reconstructions of the aging water canal and reinforcing the existing gravity flow system. However, with the increase in the urban population in the late 19th century and the introduction of water into certain institutions and private objects, supplying water became increasingly problematic and the necessity of building a new, complete water supply system increasingly apparent. The first attempt to improve the water supply took place in 1897, when a contract was made with the owner of the mills at the spring of the river Ombla, the most abundant source of potable water in this area, to transmit a certain amount of water to the old water canal.

The influence of ultrasound cavitation on the process of degradation of organic substances in wastewater of pharmaceutical production [Elektronička građa] / Uliana Y. Vashkurak, Lilia I. Shevchuk, Ivan S. Aftanaziv, Anna S. Romaniv. - Graf. prikazi.
Bibliografija: 15 jed. - Abstract ; Sažetak. - The influence of ultrasound cavitation in the atmosphere of different gases, namely oxygen, air, and nitrogen, on the destruction of impurities of butanol and ethanol found in wastewater from the pharmaceutical plant “Galichpharm” was investigated. The effect of the corresponding gases (oxygen, nitrogen, and air) without ultrasound cavitation on the destruction of ethanol and butanol impurities in wastewater was comparatively investigated. The degree of oxidation of organic matter, effective rate constants, and approximation coefficients were calculated. It was found that the air supply is the least effective for both ethanol and butanol impurities. Degradation of ethanol by air contributed to the reduction in the organic matter content by 14.6 %, while oxidation of butanol was not observed. Ultrasound cavitation enhanced the effect of air and in common action with air the ethanol impurity content reduced by 32.58 %, and butanol impurity by 4.05 %. Nitrogen bubbling produced mediocre results for the destruction of ethanol and butanol impurities giving a decrease by 17.04 % and 0.67 %, respectively. The highest results were obtained with oxygen. Ethanol impurities decreased by 22.47 % and butanol impurities by 1.75 %. With the common action of oxygen and ultrasound, much higher results were obtained, 44.32 % for ethanol impurities and 7.43 % for butanol impurities. - Ispitan je utjecaj ultrazvučne kavitacije u atmosferi različitih plinova (kisika, zraka i dušika) na razgradnju onečišćujućih tvari butanola i etanola farmaceutskih otpadnih voda tvornice “Galichpharm”. Usporedno je ispitan i utjecaj kisika, dušika i zraka bez ultrazvučne kavitacije na uklanjanje onečišćujućih tvari etanola i butanola u otpadnim vodama. Izračunati su stupanj oksidacije organskih tvari, efektivne konstante brzine i koeficijenti aproksimacije. Otkriveno je da je dovod zraka najmanje učinkovit za onečišćujuće tvari etanola i butanola. Oksidacija etanola zrakom doprinosi smanjenju sadržaja organskih tvari za 14,6 %, dok oksidacija butanola nije promatrana. Ultrazvučna kavitacija pojačala je učinak zraka i u zajedničkom djelovanju sa zrakom sadržaj nečistoća etanola smanjen je za 32,58 %, a butanola za 4,05 %. Uvođenje mjehurića dušika kod razgradnje nečistoća etanola i butanola dalo je osrednje rezultate te je utjecalo na smanjenje od 17,04 % i 0,67 %. Najviši rezultati postignuti su kisikom. Nečistoće etanola smanjile su se za 22,47 %, a nečistoće butanola za 1,75 %. Uobičajenim djelovanjem kisika i ultrazvuka dobiveni su znatno viši rezultati – za nečistoće etanola 44,32 %, a za nečistoće butanola 7,43 %.

Integrated treatment of saline oily wastewater using sono-electrokinetic process, degradation mechanism, and toxicity assessment [Elektronička građa] / Babak Darabi, Tayyebeh Tabatabaei, Fazel Amiri, Sahand Jorfi. - Ilustr., graf. prikazi.
Bibliografija: 33 jed. - Summary. - Integration of sonication (US) with electrokinetic (EK) oxidation was studied for the treatment of a saline oily wastewater, as well as the effect of operating parameters, including pH, voltage, electrode distance (ED), sonication power, and reaction time on COD removal. A COD removal of 98 % was observed for the sono-electrokinetic (SEK) process with an applied voltage of 2.5 V, US power of 300 W, initial COD concentration of 3850 mg L–1, and reaction time of 9 h. The efficiency of SEK over sonication alone and EK oxidation alone was also confirmed with a higher pseudo-first-order reaction rate constant of 0.43 h–1, compared to values of 0.13 and 0.01 for alternative processes. In addition, the biodegradability of effluent was improved based on average oxidation state (AOS) and carbon oxidation state (COS) analysis. Oxygen consumption rate inhibition, dehydrogenase activity inhibition, and growth rate inhibition methods demonstrated the low toxicity of effluent (12–15 %) compared to influent. The current work indicated that SEK is a reliable and efficient technology for the treatment of saline oily wastewaters containing recalcitrant aromatic organics.

Nitrogen removal by HN-AD bacteria immobilized on modified absorbent stone [Elektronička građa] / Wen Zhang, Zhen Zhang, Sufeng Wang. - Ilustr., graf. prikazi.
Bibliografija: 40. - Summary. - How to simplify the nitrogen removal process, reduce the cost and improve the efficiency has become an urgent problem to be solved. In this research, the isolated HNAD (heterotrophic nitrification and aerobic denitrification) bacteria were used to remove the nitrogen in wastewater. Modified absorbent stone was used as high-efficiency and low-cost immobilized material. The modification effect was determined by the changes in mechanical strength, Zeta potential, pore structure, micrographs and biomass. The practicability of the modified carrier was further proved by experiments of environmental effect and reuse. The modified carrier had excellent performance. By comparing the degradation effects of immobilized microorganism and free microorganism, it was proved that the immobilized microorganisms have broad application prospects and strong adaptability to environmental factors. Under the optimum conditions (temperature of 30 oC, pH of 7, dissolved oxygen of 3.5 mg L–1), the removal efficiency of ammonia nitrogen reached 100 % in 40 hours, the removal efficiency of total nitrogen reached 60.11 % in 50 hours, and the removal rate of total nitrogen was 2.404 mg-NL–1 h–1 by immobilized microorganisms with the treatment of simulated nitrogen-containing wastewater. This research provides new material for the immobilization of HN-AD bacteria and a new way for nitrogen removal.

Paspalum notatum grass-waste-based adsorbent for rhodamine B removal from polluted water [Elektronička građa] / Abdul Zahir, H.M. Zaheer Aslam, Umair Aslam, Ahmed Abdullah, Rizwan Ali, Mustapha Mohammed Bello. - Ilustr., graf. prikazi.
Bibliografija: 51 jed. - Summary. - The potential of Paspalum notatum grass waste to adsorb Rhodamine B dye from aqueous phase is reported in this research. The grass waste was activated and characterized through various techniques to analyze the chemical (FTIR), morphological (SEMEDX), and thermal (TGA) changes incorporated through the activation process. The pollutant removal efficiency of the raw and modified adsorbents was studied by varying different process parameters in a batch process. The maximum capacity of adsorption which was observed for grass waste and activated grass waste was 54 mg g–1 and 72.4 mg g–1 respectively. Among the various kinetic models, the pseudo-second order model gives the best regression results. However, the intraparticle diffusion-adsorption model showed that the diffusion within pores controlled the adsorption rate. Thermodynamic analysis of this process revealed that Rhodamine B adsorption was endothermic and spontaneous in nature. The results of this study show that grass waste has the potential to be used as an adsorbent for the treatment of colored water.

Utilization of Data center waste heat in northern Ostrobothnia [Elektronička građa] / Tero Leppänen, Rihard Romka, Pekka Tervonen. - Graf. prikazi.
Bibliografija: 25 jed. - Summary. - Data center industry is growing rapidly due to the expanding internet traffic and the upcoming IoT revolution. Data centers consume vast amounts of energy globally and are also a significant source of greenhouse gas emissions. There is a need to improve energy efficiency and sustainability of data center operations. The energy consumed by data centers is mostly converted to heat and this study focuses on utilizing that waste heat according to the principles of circular economy in the context of Northern Ostrobothnia, Finland. The overall regional business potential of data center waste heat utilization is evaluated and the best options of utilizing waste heat in case data center are sought. The study found that the most viable option would be utilizing waste heat locally to heat facilities or in industrial processes. Another potential option is to connect data center into a district heating system where waste heat can be fed.

ROPIN, Helmut
Electromobility and its effects on automotive workshops [Elektronička građa] / Helmut Ropin, Robert Supan. - Graf. prikazi.
Bibliografija: 37 jed. - Abstract. - Due to stricter CO2 emission limits, new competitors and imminent driving bans, electromobility has registered high growth rates in Austria. The rising number of electric vehicles not only has an impact on automobile production and its suppliers, but also on the after-sales business with the focus on the repair market. In order to meet these requirements, automotive workshops have to redesign and realign their organizational structures and they have to compensate their decreasing service-revenues. Electromobility requires additional qualification and training of employees and the expansion of technical equipment. Small workshops especially are facing this challenge. In order to obtain an answer to the current status of service companies, a qualitative study was carried out and the status was determined based on expert interviews. Recommendations for action can be derived as a result and it can be shown that there is a big difference between the independent and authorised workshops.

Research of the design feasibility of a 3-wheel electric vehicle with a simplified control system [Elektronička građa] / Srđan Medić, Veljko Kondić, Tihomir Mihalić, Vedran Runje. - Graf. prikazi.
Bibliografija: 6 jed. - Summary. - The need for a simple, customised electric vehicle (EV) has inspired the research of the possibility to build a simple EV tailored for the specific needs of the buyer. This paper is focused on the concept of an EV with no conventional control mechanism. In this paper, a research of user needs, vehicle dynamics, vehicle aerodynamics, type of drive and batteries was carried out. EV aerodynamics characteristics were simulated by using the Computational Fluid Dynamics (CFD) software. The control system was designed in correlations with the maximal safe velocity and the radius of EV turning on a circular path. The stability of the EV, concerning the vehicle turning over and wheels slipping while driving in the curves, was the main concern of this paper. The steering wheel and brake pad were replaced with a control stick. Using the Finite Element Method (FEM) analysis, key parts of the construction were constructed.

A non-destructive prediction method for wood density variations of silver birch trees growing in the Middle Volga Region, Russia [Elektronička građa] / Vladimir Ilyich Fedyukov, Musikhina Lydmila Anatolyevna, Maria Sergeyevna Chernova, Olga Viktorovna Tsoy, Nikita Andreyevich Magalyas. - Graf. prikazi.
Bibliografija: 19 jed. - Summary. - The density of wood inside the stick varies greatly according to the diameter and height of the tree. The development of a non-destructive method of predicting an average density of wood in all specific breed stem-base density in parts of the tree is of great practical importance. For this purpose, the research was conducted to identify the patterns of wood density dynamics against the height and the diameter of birch trees growing in the conditions of the Middle Volga Region in Russia. Fourteen model birch trees (Betula pendula) were selected as research material on two plots in the plantations of the Scientific-Experimental Forest District of the Volga State University of Technology (VSUT) in the Republic of Mari El of Russia. From each felled model tree 50.0 mm cross-section discs were carved at a distance of 1.3 m from the root collar and at relative heights of 0.25H, 0.5H, and 0.75H. Prototypes in the form of 20x20x30 mm rectangular prisms (long side along the wood grain) were made from their north and south sides at a distance of 0.25R, 0.5R and 0.75R from the stem core along the NS diagonal. Density studies were conducted by measuring the density of the wood sample immersed in liquid against the buoyant force. It has been revealed that there are both differences and patterns of change in density in the longitudinal and cross-section directions of the trunk of a birch tree growing in the conditions of the Middle Volga Region in Russia. Based on the results obtained, a mathematical model of these laws has been formulated. Сlose relationship between the average density of the stick and its diameter at breast height (DBH) cross-section average density, i.e. ρtree=178.52+0.641ρdbh (r=0.922) has been revealed.

Diameter structure changes in the pre-maturing black locust and common hackberry stand in the Subotica-Horgoš sands under the influence of a late thinning [Elektronička građa] / Siniša Andrašev, Martin Bobinac, Tomislav Dubravac, Nikola Šušić. - Ilustr., graf. prikazi.
Bibliografija: str. 15-16. - Summary. - In this paper, a change of diameter structure in a pre-maturing stand of black locust and common hackberry under the influence of a late thinning is analysed. The research is based on three permanent experimental plots and two measurements of diameters in a five-year period. One of the plots is a control plot and two plots are experimental, where the thinning was carried out in a stand 28-years old, with the thinning intensity of 28.9–30.6% of the initial density, approximately evenly distributed across diameter classes. In the investigated stand common hackberry came from the neighbouring areas in the stand structure. The initial measurement in the autumn of 2014 confirmed the share of common hackberry of 16–18% in the total number of trees thicker than 5 cm with a dominantly reversed J shape of the diameter structure and the presence of trees in all the diameter classes. In the period of stand age from 28 to 33 years, a dominant process on all treatments was the mortality of thinner trees, while the recruitment of common hackberry trees was recorded in all treatments. On the control plot, a quarter of the trees died, while an eighth of the remaining trees died in the thinned plots, mostly black locust trees. In thinned plots, only black locust trees died with a characteristic that the intensity of mortality was higher in thinner trees, while in the control plot some thick black locust trees died, as well as and some thinner common hackberry trees. In the five-year period, numerical parameters of variability (standard deviation, coefficient of variation), the shape of distributions (skewness and kurtosis) and heterogeneity of diameters at breast height (Gini index, Lorenz asymmetry coefficient) have shown a trend of increasing variability and change of diameter distributions of trees in all treatments, but it is more expressed in thinned plots compared to the control plots.

DNA barcoding of fungi in the forest ecosystem of the Psunj and Papuk mountains in Croatia [Elektronička građa] / Nevenka Ćelepirović, Sanja Novak Agbaba, Monika Karija Vlahović. - Ilustr., graf. prikazi.
Bibliografija: str. 7-8. - Summary. - The saprotrophic, endophytic, and parasitic fungi were detected from the samples collected in the forest of the management unit East Psunj and Papuk Nature Park in Croatia. The disease symptoms, the morphology of fruiting bodies and fungal culture, and DNA barcoding were combined for determining the fungi at the genus or species level. DNA barcoding is a standardized and automated identification of species based on recognition of highly variable DNA sequences. DNA barcoding has a wide application in the diagnostic purpose of fungi in biological specimens. DNA samples for DNA barcoding were isolated from infected tree tissues, fungal fruiting bodies or fungal cultures. The ITS or ITS2 sequences of the fungal DNA were sequenced and aligned with the reference sequences in GenBank (NCBI) using BLAST. The size of ITS and ITS2 sequences were 512-584 bp and 248-326 bp, respectively. The sequences showed a high identity of 97.21%-100% at 98%-100% coverage with reference sequences in GenBank (NCBI). The exception was the species Amphilogia gyrosa that showed 95.65% identity at 100% coverage. Two fungi were determined at genus level: Cladosporium sp., and Cytospora sp., while 11 fungi were determined at species level: Alternaria alternata, Aureobasidium pullulans, Amphilogia gyrosa, Capronia pilosella, Cryphonectria parasitica, Exidia glandulosa, Epicoccum nigrum, Penicillium glabrum, Pezicula carpinea, Rosellinia corticium, and Stereum hirsutum.

Ectomycorrhizal flora formed by main forest trees in the Irtysh River region of central and northeastern Kazakhstan [Elektronička građa] / Dani Sarsekova, Sezgin Ayan, Abzhanov Talgat. - Ilustr., graf. prikazi.
Bibliografija: str. 8-9. - Summary. - In this study, the aim was to determine and identify symbiotically living ectomycorrhizas of the main tree species forming forests in central and northeastern Kazakhstan. Surveys were conducted on the right bank of the Irtysh River in a mixed forest of Pinus sylvestris, Picea obovata and Betula pendula trees. The collection was formed and the primary identification of voucher samples of fruiting bodies of macromycetes collected as ectomycorrhiza forming fungi was completed. In the collection and species identification of fruiting bodies, standard methods were used. A total of 30 ectomycorrhizas belonging to Agaricomycetes were identified. The distribution of 30 species into families is as follows: Suillaceae (8), Russulaceae (7), Cortinariaceae (4), Boletaceae (3), Tricholomataceae (2), Amanitaceae (1), Cantharellaceae (1), Gomphaceae (1), Gomphidiaceae (1), Paxillaceae (1), and Bankeraceae (1). The richest genus on account of the number of species was Suillus (8). Concerning the woody host species, 17 mycorrhizas were determined to build symbiosis with P. sylvestris, 8 mycorrhizas with B. pendula, 6 mycorrhizas with Populus tremula, 1 mycorrhiza with P. obovata, 1 mycorrhiza with Quercus robur, 1 mycorrhiza with Salix sp., and 1 mycorrhiza with Pinus densiflora Siebold and Zuccarini. Ectomycorrhizas should be used as a major performance-enhancing tool in afforestation and restoration studies in the Irtysh River basin under extreme ecological conditions and under climate change effects.

TATSUHARA, Satoshi
Estimating potential woody biomass supply under sustainable timber production from plantation forests in a snowy mountainous region of Japan [Elektronička građa] / Satoshi Tatsuhara. - Graf. prikazi.
Bibliografija: str. 10-11. - Summary. - Numerous woody biomass-powered stations for energy generation have been constructed in Japan since the Feed-in Tariff Scheme was introduced. However, a stable, long-term woody biomass supply from plantation forests is necessary for the construction and operation of such power stations. The logs that are used to produce fuel chips are harvested from roundwood. Thus, the main objective of this study was to estimate the potential supply of woody biomass resources under the condition of maximum sustainable harvesting from privately-owned plantation forests. Another aim was to examine the stability of sustainable harvest volumes from periodical changes. The study focused on privately-owned forests in the Sampoku district of Murakami City in the northernmost part of Niigata Prefecture, Japan. Trees in the studied region are commonly bent during periods of high snowfall, and the current bucking strategy – influenced by the construction of a biomass-powered generation facility – was integrated into the model. The revenues and costs of plantation management and timber production were calculated based on stands’ geographical attributes using a geographic information system. A mixed integer programming model was used to predict the maximum sustainable harvest levels that would provide stable profits. The simulation showed that even though the trees had a unimodal age class distribution, sustainable harvest volumes ensured a sustainable supply of woody biomass over various rotation ages. Extending the range of rotation ages by 20 years dramatically increased the potential supply of woody biomass resources. Fluctuations in each woody biomass resources were mostly less than 20% over the planning horizon. The presented research could be useful to regional forest resource managers and stakeholders involved in biomass-powered energy generation or the purchasing of woody biomass.

First dendroclimatological insight into Austrian pine (Pinus nigra Arnold) climate-growth relationship in Belgrade area, Serbia [Elektronička građa] / Branko Stajić, Marko Kazimirović, Vojislav Dukić, Nenad Radaković. - Graf. prikazi.
Bibliografija: str. 7-8. - Summary. - In order to assess the impact of climate variations on Austrian pine forest in the Belgrade area, the radial growth of artificially-established Austrian pine trees and its dependence on temperature and precipitation was studied using dendroclimatological methods. The site is classified as Quercetum-frainetto cerris Rudski. Standard and residual chronologies were established and several common statistics were calculated. A dendroclimatic study was carried out using the correlation and response function analysis. The Pearson correlation coefficients between the chronology indices and 13 seasonal (3-month period) precipitation and temperature data were calculated for the period from 1959 to 2014. The applied response function analysis included 24 precipitation and temperature variables from October of the prior year to September of the current year. The results of the correlation analysis pointed out that there was a strong tendency towards a positive response to the summer and late summer/early autumn precipitation and a weak significant negative response to the spring and summer temperatures. Climate-growth relationships were further first studied using the response functions for the significant seasons that were detected from the correlation analysis and then for individual months from previous October to current September. These results also highlighted the findings that higher precipitation in the current summer months has a beneficial effect on the tree-ring width. The conducted correlation between the residual chronology and the Standardised Precipitation Evapotranspiration Index indicated that a high summer value of this drought index had a positive impact on the pine growth and reinforced the previously detected relevance of September as an important month for the Austrian pine growth.

First record of Cacopsylla pulchella (Hemiptera, Psyllidae) in Albania [Elektronička građa] / Ejup Çota, Marta Kovač, Milan Pernek. - Ilustr., graf. prikazi.
Bibliografija: 22 jed. - Summary. - The aim of this study is to identify plant lice Cacopsylla pulchella as a new alien insect in the fauna of Albania. In order to assess the potential of this insect as a pest causing damages on trees, infestation level assessment was used. In the first decade of June 2020 samples were collected at three locations in Albania, where Cercis siliquastrum is grown. Samples were collected and brought to the laboratory for further analysis. Field research was performed to assess distribution and infestation intensity across various localities. The intensity of infestation was assessed by visual examination and was categorized according to previously determined categories. C. pulchella was confirmed on C. siliquastrum in three localities in Albania. Most of the infested trees had a moderate or high intensity of infestation. Compared to the results of other countries, it seems that the Judas trees are under heavy attack in Albania. Librazhd and Elbansn districts had the highest recorded infestation level. Infested trees found in this study should be inspected in the following years and this alien insect should be further monitored in order to estimate its potential of becoming an invasive pest in this country.

Bibliografija: 23 jed. - Summary. - The aim of this study is to identify plant lice Cacopsylla pulchella a new alien insect in the fauna of Croatia. We propose a new method of infestation level assessment in order to assess the potential of this insect as a pest. In May 2020 samples were collected from eleven locations in Croatia, where Cercis siliquastrum is grown in parks. Adults and nymphs of C. pulchella were collected together with a plant material and brought to entomological laboratory for further analysis. Field research was performed in order to assess the distribution and infestation intensity across various localities in Croatia. The intensity of infestation was assessed heuristically by visual examination and was categorized in four categories: 0) no infestation, 1) low, 2) moderate and 3) high infestation. C. pulchella was confirmed on C. siliquastrum in eleven localities in Croatia. Most of the infested trees had a low or moderate intensity of infestation. Damages caused by this insect are due to the emission of honey dew, a small spherical drop covered with waxy secretion causing necrotic areas which could lead to the premature fall of the leaves. It is not known what kind of progress in infestation intensity could be expected so infested trees found in this study should be checked closely in the coming years. It is strongly suggested to continue the monitoring of this alien insect on C. siliquastrum in Croatia and to estimate its potential of become an invasive pest which could endanger ornamental and other values of its hosts.

Growth of Tilia cordata Mill. in urban forests [Elektronička građa] / Maria Martynova, Rida Sultanova, Georgiy Odintsov, Regina Sazgutdinova, Elvira Khanova. - Ilustr., graf. prikazi.
Bibliografija: str. 8-9. - Summary. - Tilia cordata Mill. is considered to be the main tree species resistant to urban conditions and it is widely used in the greening of cities. The aim of the study is to assess the patterns of growth and development of small-leaved linden plantations in the urban environment. The research is based on the method of sample areas where continuous enumeration survey has been carried out. The study of urban greening objects was conducted using the methods of landscape assessment and complete enumeration of trees in alley plantings. It was found that Tilia cordata Mill. grows in all districts and zones of the city of Ufa, occupying 34.4% of green areas. During this research it was found that artificially created alley plantings of Tilia cordata Mill. are more well-kept and have well-developed crowns which create a tree shade sometimes 8-10 meters wide (the average crown projection being 7 m). Since alley plantings have repeatedly been pruned, trees in this area are characterized by a large increase in diameter and strong height growth stagnation. Thus, when studying linden plantings of the same age, a sharp difference in the size and shape of trees was observed.

In vitro lead tolerance testing in white poplar genotypes on acidic medium [Elektronička građa] / Branislav Kovačević, Gordana Tišma, Nataša Nikolić, Marina Milović, Vanja Vuksanović, Saša Orlović. - Ilustr., graf. prikazi.
Bibliografija: str. 159-160. - Summary. - This study evaluates in vitro tolerance of white poplar genotypes to the presence of lead in an acidic rooting medium. Lead was supplemented in form of Pb(NO3)2, in the following concentrations: 0 M (Control), 10-6 M, 10-5 M, 10-4 M and 10-3 M. After four weeks of cultivation, the following characters were measured: number of roots, the length of the longest root, the shoot height, dry root mass and dry shoot mass, and parameters related to photosynthetic pigments: content of chlorophyll a, b, a+b, and of carotenoids in fresh mass, as well as chlorophyll a/b ratio. For further statistical analysis, tolerance indices by Turner and Marshal (TI) were calculated for each measured character. The strongest inhibitory effect was achieved on the medium with 10-4 M Pb(NO3)2, but the best differentiation between genotypes was achieved on the medium with 10-5 M Pb(NO3)2. The highest tolerance indices for the length of the longest root and shoot height had genotypes L-12 and LBM, and for root and shoot dry mass genotypes LCM and L-12. There were no significant differences between genotypes in tolerance indices by any of the examined photosynthetic parameters. The obtained results suggest that both low pH and the presence of citric acid as chelating agent improved evaluation of lead tolerance in comparison with the results obtained on media with standard pH and without citric acid in similar studies. In vitro tests on acidic medium with citric acid can efficiently differentiate examined genotypes for lead tolerance, which could be important for their use in phytoextraction projects, especially on acidic soils.

Interaction between the effects of provenance genetic structure and habitat conditions on growth of Scots pine in international provenance tests in Bosnia and Herzegovina [Elektronička građa] / Mirzeta Memišević Hodžić, Semir Bajtić, Dalibor Ballian. - Graf. prikazi.
Bibliografija: 15 jed. - Summary. - Scots pine (Pinus sylvestris L.) is one of the most important tree species in European forests, characterized by high genetic variability and complex population structure. This research aimed to determine whether there is an interaction between the effects of provenance genetic structure and habitat conditions on the growth of Scots pine in two international provenance tests in Bosnia and Herzegovina, to chose the best provenances for both habitats. For this research, heights and root collar diameters of Scots pine plants on two provenance tests in Bosnia and Herzegovina were measured and the interaction between the effects of provenance genetic structure and habitat conditions for these two traits was estimated based on regression. Eleven provenances represented on both tests were researched. Provenance tests were established in 2012 on two locations with contrasted ecological conditions: Kupres and Žepče. By assessing the interaction between the effects of provenance genetic structure and habitat conditions on Kupres and Žepče provenance tests, two interactions for the height of plants (between Germany NJ2 and Italy I2 and between Austria A2 and Romania R1) and one interaction for the root collar diameter (between Austria A1 and Italy I2) were identified. The number of survived plants and their productivity is different for all provenances in both habitats, indicating that the adaptability of provenances is not only conditioned by their genetic constitution but also by habitat conditions. Considering the productivity of provenances and the number of survived plants in both habitats, Austria A1, Austria A2, Austria A3, and Poland P1 provenances showed the best adaptability. The results of this study can be used in the process of Scots pine breeding and for its conservation by in situ and ex-situ methods.

Long-term forest dynamics of oromediterranean fir forests in Greece [Elektronička građa] / Robert Brandes, Anastasia Christopoulou. - Ilustr., graf. prikazi.
Bibliografija: str. 81-84. - Summary. - The present study illustrates the situation of the genus Abies in the Mediterranean and in Greece, focusing in detail on the oromediterranean forest of the southern Peloponnese, at Mt. Taygetos. The existing pattern of forest dynamics (mosaic cycle) and also the timberline dynamics are presented and explained. Since fir forests are highly susceptible to drought-related impacts (fire and fir dieback: insect outbreaks/ forest pathogens), the analysis of the present situation is put into perspective by looking at the role of direct human influence and the climatic fluctuations of the past, taking into consideration dendrochronological findings and archival climate records. In view of climate warming the question is whether in recent decades the fingerprints of climate change can already be observed in the Greek fir forests. The study concludes that drought periods and climatic extremes have been an essential part of Greek climate for many centuries, causing high natural forest vulnerability. Therefore, fir dieback and fires are not a new phenomenon either – but in recent decades the accumulation of fuel, caused by land abandonment, has increased the danger of large wildfires. Nevertheless, the Greek mountain forests are highly endangered by increases in aridity and/or more frequent climate extremes (heat waves), together with increased risk of wildfires. Recommendations for an active forest management (counteracting expected adverse effects of climate change, by focusing on the establishment of an Abies cephalonica Loudon /Pinus nigra J. F. Arnold mosaic cycle) and further scientific research are provided.

Mesophilous Quercus frainetto dominated forests from Western Balkans [Elektronička građa] / Vladimir Stupar. - Ilustr., graf. prikazi.
Bibliografija: str. 13-14. - Summary. - Hungarian oak (Quercus frainetto) has dominant or co-dominant role in many thermophilous deciduous forest communities in the Balkan Peninsula. However, recent field research in the north-western margin of its range has revealed that some stands have a pronounced mesophilous character, which was also supported by data from the literature. This paper aims to analyze this mesophilous community of Hungarian oak which is found in north-western Serbia, north-eastern Bosnia and Herzegovina (B&H) and eastern Croatia. Numerical analysis, which included classification and ordination of all 474 available relevés of Hungarian oak forests from the western and central Balkans, along with the 43 relevés of mesophilous forests of oak-hornbeam from B&H, have shown that 83 mesophilous Hungarian oak relevés are floristically and ecologically more similar to mesophilous forests of sessile oak-hornbeam (Erythronio-Carpinion) than to xero-thermophilous forests of Qeurcion confertae. The new association Carpino betuli-Quercetum frainetto ass. nova hoc loco was described, floristically and ecologically characterized and assigned to mesophilous oak-hornbeam forests of Erythronio-Carpinion. The study also discusses the syntaxonomical issues of Quercion confertae and its central association Quercetum frainetto-cerridis, considering the problem of the lack of good diagnostic species for both syntaxa, and introduces possible ways of dealing with these issues.

Potential hazard of open space fire in black pine stands (Pinus nigra J.F. Arnold) in regard to fire severity [Elektronička građa] / Damir Barčić, Tomislav Dubravac, Marko Vučetić. - Graf. prikazi.
Bibliografija: str. 7-8. - Summary. - Black pine (Pinus nigra J.F. Arnold) is one of the most important reforestation species for dry and rocky terrain in the sub-Mediterranean zone. Fire is an important factor in black pine stands that largely defines the distribution range of black pine and the floristic composition of its stands. Fire causes less damage during autumn or early spring when tree cones contain ripe seeds that can partially reforest burnt surfaces. Every fire is a potentially significant threat to forest habitats. There are many damages, from direct damages to wood mass and reforestation costs, to indirect ecological, edaphic, protective damages and the loss of biological diversity. The aim of prevention works in forestry is to reduce the number of fires and reduce burnt surface area per fire. Research was based on vegetation analysis performed on each experimental plot in a black pine stand. The assessment of fire severity was performed using the Canadian Forest Fire Weather Index (FWI). The assessment of the severity of fire indicates the suitability of conditions for the occurrence of forest fires, and enables sound and effective protective methods beginning with silvicultural works. The results indicate better quality stands in the higher parts of the sub-Mediterranean area. Taking into account the climatic parameter, the areas on the border with the continental climate have better habitat conditions for black pine. Also, attention should be focused on 2012 and 2015. High values (Figure 13 – 16.22, Figure 11 – 6.99, Figure 8 – 8.38, Figure 7 – 12.02 and 12.25, Figure 5 – 8.32) indicate the overlapping of extremely dry periods and extremely high summer temperatures, and probably a strong wind influence that further increases the index. Fire severity assessments indicate the suitability of conditions for the onset of fire.

Predicting diameter at breast height from stump measurements of removed trees to estimate cuttings, illegal loggings and natural disturbances [Elektronička građa] / Lucio Di Cosmo, Patrizia Gasparini. - Graf. prikazi.
Bibliografija: 21 jed. - Summary. - Predicting diameter at breast height (DBH) of trees from stump information may be necessary to reconstruct silvicultural practices, to assess harvested timber and wood, or to estimate forest products’ losses caused by illegal cuttings or natural disasters (disturbances). A model to predict DBH of felled trees was developed by the first Italian National Forest Inventory in 1985 (IFNI85). The model distinguished between the two broad groups of conifers and broadleaves and used stump diameter as the sole quantitative variable. Using an original dataset containing data from about 1200 trees of sixteen species recorded throughout Italy, we assessed the performance of that model. To improve the prediction of the DBH of removed trees over large areas and for multiple species, we developed new models using the same dataset. Performance of the new models was tested through indices computed on cross-validated data obtained through the leave-one-out method. A new model that performs better than the old one was finally selected. Compared to the old NFI model, the selected model improved DBH prediction for fourteen species up to 31.28%. This study proved that species specification and stump height are variables needed to improve the models’ performance and suggested that data collection should be continued to get enhanced models, accurate for different ecological and stand conditions.

Tree growth variability of Pinus heldreichii at tree-line locations in Kosovo [Elektronička građa] / Faruk Bojaxhi, Ervin Toromani, Nehat Çollaku. - Ilustr., graf. prikazi.
Bibliografija: 26 jed. - Summary. - It is well-known that tree growth at the upper treeline is controlled by low temperatures and limited seasonal growth. The study’s objective was to investigate the climate warming effects on Bosnian pine (BP; Pinus heldreichii Christ.) growth during the 20th century. We hypothesized that, like all the other drought-stressed conifers growing on tree-line locations, BP responds significantly to climate factors that control their growth. Three natural forest stands of BP were selected in Prevalla, Decan and Koritnik. The cores were taken from 98 dominant and co-dominant BP trees at breast height with no sign of human interference. The tree-ring widths were measured at 0.001 mm precision, with a LINTAB 6 (RINNTECH, Heidelberg) system and TSAP-Win Scientific software. A set of three BP tree-ring width chronologies were developed by trees spread on a typical mountain slope at elevations ranging from 1815 to 1945 m above sea level. The tree-ring chronologies from three sites showed significant correlation and this agreement decreased with the distance between sites. The length of the master chronologies varies among sites ranging from 176 years (Koritnik) to 541 years (Decani). The tree growth was controlled by a common climatic signal (local temperatures) and drought during midsummer across the investigated sites. These results confirm the assumption that tree growth at tree-line sites is controlled by low temperatures and drought conditions during the midsummer.

Use of a common garden experiment in selecting adapted beech provenances for artificial stand restoration [Elektronička građa] / Sanja Bogunović, Saša Bogdan, Miran Lanšćak, Nevenka Ćelepirović, Mladen Ivanković. - Ilustr., graf. prikazi.
Bibliografija: str. 9-10. - Summary. - Increased frequency of extreme weather events has seriously affected forestry operations in south-eastern Europe. A precondition for effective artificial restoration of disturbed forest stands is site-adapted forest reproductive material (FRM). Common garden experiments (provenance trials) may assist in selecting such FRM. The main objective of this study was to establish among-provenance variation pattern using data from a beech provenance trial. Usefulness of the results in selecting seed sources for restoration of European beech stands is discussed. The trial was set up in 2007, at a slope of Medvednica mount facing north-west at 730-750 m above sea level. Plant heights were measured and survival scored in 2008 and 2015. Height increments were calculated and processed to determine variance components due to various effects. Highly significant provenance-by-block interaction was revealed, indicating strong microsite effects on provenance performances. Therefore, corrections were made and provenance mean height increments recalculated. Provenance mean height increment multiplied with survival was used as a measure of a provenance’s adaptedness. Regression tree (RT) analysis was used to determine the pattern of among-provenance variations. A set of provenance clus­ters was grown using climatic variables related to the provenance stands of origin as criteria. All analyzed effects were significant (provenance: F=2.07, p<0.05; block: F=5.07, p<0.05; provenance by block interaction: F=7.32, p<0.001). Data corrections reduced the interaction effect, thereby increasing reliability of calculated provenance adaptedness indices (AI). Provenances were grouped into 4 clusters due to elevation, mean July temperature and summer heat-to-moisture index (SHM). Cluster 4, containing provenances from the highest altitudes (>750m), had the highest mean AI (143.9±8.4 cm).

Who are the visitors of Forest Park Grmoščica and what are their needs? [Elektronička građa] : Results of quantitative exploratory survey / Martina Kičić, Ana Marija Marin, Dijana Vuletić, Ivana Kaliger, Ninoslav Matošević, Sergej Šimpraga, Silvija Krajter Ostoić. - Graf. prikazi.
Bibliografija: str. 178-180. - Summary. - Forest Park Grmoščica is an important part of urban green infrastructure for the citizens of the western part of the city of Zagreb. To enhance the quality of management of the forest park to the satisfaction of its daily users, it is important to know their socio-demographic characteristics, visiting behaviour, recreational activities, as well as their perception of the forest park. The survey for users of the Forest Park Grmoščica was developed within the INTERREG DANUBE’s URBforDAN project. It was filled out by visitors of the forest park using on-site face-to-face method and was also available online. The results of the survey provided information about the users of the Forest Park Grmoščica, their socio-demographic data, visiting habits and perception. Also, the typology of users was given depending on the activities they undertake in the forest park (cyclists, joggers, visitors who spend time in Forest Park Grmoščica with their families, and pet walkers) and their main characteristics. The obtained data can improve the management of the Forest Park Grmoščica in such a way that it fulfils its social and ecological function and is adapted to the needs of its users.

Assessment of physiological strain in male food crop cultivators engaged in manual threshing task in a southern district of West Bengal [Elektronička građa] / Ayan Chatterjee, Sandipan Chatterjee, Neepa Banerjee, Shankarashis Mukherjee. - Graf. prikazi.
Bibliografija: 37 jed. - Summary. - The impact of rise in ambient temperature is not confined to output; it has an impact on the work performance of human beings associated with occupational activities in informal sector, especially those carried out in the open field under the sky. The agricultural workers are constrained to work manually all through the day irrespective of disparity in working situation existing in the working environment. Hence, there is an urgent need to study the cardiac performance status in terms of indicators of physiological strain of the human resources. In this backdrop, the present study has been undertaken to assess the degree of physiological strain in male food crop cultivators’ (age range 24 - 36 years) engaged in manual threshing (separating the grains from the rice straw by manually - by hand i.e. beating method) during paddy cultivation time. Moreover the magnitude of physiological strain was significantly higher (P <0.5) during “Boro” type of paddy cultivating time.

Društveno odgovorno poslovanje u agroturizmu Republike Hrvatske [Elektronička građa] / Marina Gregorić, Đurđa Somođi, Tena Kovačić. - Graf. prikazi.
Bibliografija: 10 jed. - Sažetak ; Summary. - Predmet istraživanja ovoga rada je primjena društveno odgovornog poslovanja u agroturizmu, „seljačkom turizmu“ ili „turizmu na obiteljskim poljoprivrednim gospodarstvima“ u Republici Hrvatskoj. Cilj je istražiti trendove društveno odgovornog poslovanja kroz poduzetničke aktivnosti u turističkom sektoru koji se odnosi na obiteljska poljoprivredna gospodarstva s tendencijom njihova razvoja u kombinaciji s određenim kontekstualnim čimbenicima. Metode korištene u ovome radu su povijesna, metoda analize i sinteze, indukcije i dedukcije te empirijska kvantitativna metoda putem instrumenta strukturiranog upitnika na uzorku poduzetnika koji posluju kao seoska obiteljska gospodarstva (OPG) na području Republike Hrvatske. Također su provedeni i dubinski intervjui s predstavnicima i vlasnicima obiteljskih poljoprivrednih gospodarstava. Prikupljeni podaci obrađeni su deskriptivnom statistikom te je provedena analiza primjene društveno odgovornog poslovanja u tom segmentu turističke ponude. Praktična implikacija istraživanja je da se društveno odgovorno poslovanje ne smije zanemarivati jer je ona pretpostavka za postizanje poslovne konkurentske prednosti u kombinaciji s promjenom nacionalne kulture primjenjivanja društveno odgovornog poslovanja u agroturizmu. - The subject of this paper is the application of corporate social responsibility in agritourism, “peasant tourism” or “tourism at family farms” in the Republic of Croatia. The aim is to explore the trends of corporate social responsibility through entrepreneurial activities in the tourism sector that relate to family farms, with the tendency of their development in combination with certain contextual factors. The methods used in this paper are the historical method, methods of analysis and synthesis, induction and deduction, and empirical quantitative method using a structured questionnaire instrument on a sample of entrepreneurs operating as rural households (OPGs) in the Republic of Croatia. In-depth interviews were also conducted with representatives and owners of family farms. The collected data was processed with descriptive statistics and an analysis of the application of socially responsible business in this segment of tourism. The practical implication of the research is that socially responsible business must not be neglected because it is a prerequisite for achieving competitive advantage and should be combined with the change of national culture with regards to applying socially responsible business in agritourism.

The food insecurity status of pastoral and agro-pastoral households in Ethiopia [Elektronička građa] / Eticha Abebe Abera, Ahmed Endris Mossa. - Graf. prikazi.
Bibliografija: 9 jed. - Summary. - Understanding the major causes of food insecurity is important for interventions aiming at minimizing food insecurity. Therefore, this study was conducted to assess the status of food insecurity of pastoral and agro-pastoral households of Seba Boru Woreda Guji Zone, Oromia National Regional State, Ethiopia. In order to achieve these objectives, 112 respondents’ agro pastoralists were selected from 2 kebeles (the smallest administrative unit). To this end, both probabilities (stratified, systematic and random) and non-probability (purposive) sampling techniques were employed. Primary and secondary data were collected from various sources. The data were analysed using descriptive statistics like mean standard deviation, percentage and frequency distributions. Univariate analysis such as t-test and chi-square (χ2) were also used to describe the characteristics of food secured and food insecure groups. The survey result shows that about 60 (53.7 %) of sample respondents were food insecure while only 52 (46.3 %) were food secure. As per a binary logistic model regression, four variables such as family size, land, income, and extension service were significant at 10 % probability levels. Finally, limiting population size through integrated health and education service, intensification of agriculture through extension service by strengthening PTC (pastoral training center), are some to recommend to curb food insecurity in the area.

T-standpoint assists the waiting of predatory birds in lucerne [Elektronička građa] / Ana-Marija Simunić, Ranko Gantner, Ivica Bošković, Gordana Bukvić, Vesna Gantner. - Ilustr., graf. prikazi.
Bibliografija: 7 jed. - Summary. - Field rodents can cause considerable economic losses in perennial crops, especially lucerne. Predatory birds can provide biological control of field rodent populations. However, modern arable landscape usually provides few or no natural standpoints for predatory birds to wait for their prey. According to the old farmers in eastern Croatia, T-standpoints installed into lucerne were traditional implements assisting the bird predation over field rodents. Aim of this study was to check whether the T-standpoints really are appropriate installations for the predatory birds to wait for their prey on the ground or not. The research has confirmed that predatory birds (Buteo buteo and Falco tinnunculus) descended on the installed T-standpoints (in average 1.35 arrivals per day of observation), waited (average period of stay was 17 minutes in the morning and 34 minutes in the afternoon) and landed on the ground, most probably to catch the prey (in average 13 % of arrivals to T-standpoints ended with landing to the ground, likely for the prey attack). Small forest restoration in arable landscapes and less chemical rodent control would probably improve the predatory bird populations, thus enhancing the biological control of field rodents. There remains the need for further investigation of efficiency of field rodent control by predatory birds.

Transformation towards sustainable business models in production [Elektronička građa] : a case study of a 3D printer manufacturer / Shahban Ali Shah, Philipp Url, Wolfgang Vorraber, Thomas Janics, Matthias Katschnig. - Ilustr.
Bibliografija: 29 jed. - Abstract. - A global transformation from Industry 4.0 towards Industry 5.0 will soon take place. Such transformations are intrinsic to human and sustainable value creation. An increasing number of companies, recognising this imminent trend, will need to transform their current classical, solely profit-oriented business models into sustainable business models that also target human, social, and environmental aspects. Various frameworks already exist that support the design of sustainable business models. Practical applications of these frameworks and research on the transformation process in the production domain, which places a special focus on small and medium enterprises, is still scarce. This paper presents the first results from a sustainable business model transformation project on a European SME, which produces 3D printers. The research method applies a single case study design. The study was based on publicly available information and qualitative data, obtained through interviews and workshops carried out on an executive management level.

Spectral and energy efficient D2D communication underlay 5G networks [Elektronička građa] : a mixed strategy approach / Selmi Sawsan, Ridha Bouallègue. - Ilustr. ; graf. prikazi.
Bibliografija: 20 jed. - Abstract. - 4G is now deployed all over the world, but requirements are about to change rapidly face to the exponential growth on devices number, local service applications and spectrum scarce. To deal with that, 5G networks integrated Device To Device (D2D) communication as a key technology in its evolving architecture. From 3GPP Rel-12 to Rel-16, D2D succeeded to improve network capacity by enhancing spectrum reuse, data rates and reducing end-to-end latency. However, despite all these advantages, it implies new challenges in 5G system design as interference, spectrum and energy consumption. As a contribution, we propose in this paper a joint spectrum and energy efficient resource allocation algorithm for D2D communications. This approach maximizes the total spectrum efficiency and reduces UEs power consumption. Contrarily to most of previous studies on resource allocation problems considering only centralized and pure strategies approaches, we propose a distributed algorithm based on new mathematical game theory model as an interpretation of mixed strategy non cooperative game. We extend our previous research, by focusing on power consumption issue. Our proposed solution enhances joint SE/EE tradeoff by minimizing interferences and power consumption via a smart RB allocation. This new approach allows users to adopt more accurate strategies and maximize their utilities according to the random network behavior.

Značajke razvoja javne telefonije u Hrvatskoj od 1990. do 1998. godine [Elektronička građa] / Goran Rajič. - Graf. prikazi.
Bibliografske bilješke uz tekst ; bibliografija: str. 94-97. - Sažetak ; Summary. - Tema članka je razvoj javne nepokretne i pokretne telefonije u Hrvatskoj pod okriljem novoosnovane nacionalne javne poštansko-telekomunikacijske tvrtke Hrvatska pošta i telekomunikacije od 1990. pa sve do njezina razdruživanja na dvije zasebne tvrtke: Hrvatska pošta d.d. i Hrvatske telekomunikacije d.d. početkom 1999. godine. Hrvatska je u razvoju javne telefonske mreže znatno zaostajala za razvijenim europskim zemljama, a izbijanje Domovinskoga rata i oružana agresija na Republiku Hrvatsku izložili su ju mogućnosti telekomunikacijske i informacijske blokade. Budući da su se građani Hrvatske opredijelili za tržišnu ekonomiju, politički pluralizam i demokratsko društveno uređenje, u načelu se podrazumijevala i poticala sloboda neposrednoga komuniciranja, a ona je, telekomunikacijski gledano, na razini pojedinca ponajviše bila izražena u dostupnosti domaćih i međunarodnih javnih telefonskih veza. U obrađenom su razdoblju na nacionalnom planu napravljeni ključni infrastrukturni zahvati i uvedena je suvremena tehnologija s novim telekomunikacijskim uslugama, što je omogućilo da Hrvatska prestane biti telekomunikacijski nerazvijena, a na međunarodnom planu postala je prepoznatljiv telekomunikacijski partner te dio tranzitnoga telekomunikacijskog mosta između istočne i zapadne te sjeverne i južne Europe. - After the independence of the Republic of Croatia was declared in 1991, the newly-formed national postal and telecommunications company HPT (Croatian Post and Telecommunications) found itself in an unenviable position. Croatia was in the group of countries at the forefront of telecommunications development in Europe. In 1990, it had only 17 telephone connections per 100 inhabitants. However, in the next eight years it moved closer to the European average, doubling its capacity to 35 telephone lines per 100 inhabitants by 1999. It did so despite the devastation of the Homeland War and the enormous damage suffered by its public telephone network. Croatia managed to negate the telecommunications blockade by finding alternative telecommunication routes, and then set out to build an efficient telephony and transmission system based on the use of fibre-optic cables and modern switching equipment. By the end of 1993, international switching hubs in Zagreb, Split, Rijeka, and Đakovo using AXE 10 technology were built, and the following year cities on the Croatian Adriatic coast were connected with cities in continental Croatia by fibre-optic cable. During this process, Croatia received its one-millionth telephone subscriber. Thanks to its participation in the TEL (Trans Europe Line) project, it became part of the telecommunication bridge between Eastern and Western Europe. In addition to the fixed public telephone network, it simultaneously developed a mobile public telephone network, first an analogue mobile network aptly named MOBITEL in 1991, and then the CRONET digital mobile network in 1996. These steps resulted in a significant increase in telephone traffic and the widespread availability of fixed and mobile telephone connections, which completely revolutionised public telephony in Croatia.

Influence of the varnishing "surface" coverage on optical print characteristics [Elektronička građa] / Tomislav Hudika, Igor Majnarić, Tomislav Cigula. - Ilustr.
Bibliografija: 17 jed. - Abstract. - Varnishing is often used to protect or decorate the print, but it can also influence the print’s colour appearance. Therefore, varnishing should enhance the print role, while colour change should be kept as low as possible. The aim of this paper is to evaluate inkjet UV LED varnishing by estimating optical print characteristics. Prepared offset prints were UV LED varnished in different surface coverage values (SCV) with a matte and gloss finish. The prints were evaluated by measuring gloss and colour coordinates. Secondly, varnishing was performed in a different SCV, which enabled assessing the optimal SCV, i.e. the most cost-efficient varnishing. The printing process was conducted in a standardized and controlled laboratory environment, regulated via the ISO 12647-2:2013 norm to ensure that the black colour was reproduced in the standard tolerance. The results showed that the colour difference is negligible (stays in the ISO tolerances), regardless of the varnishing SCV. On the other hand, the optimal printing gloss is at the SCV of 100%.

Infrared printing technique for the security marking of traceability certificates for meat products [Elektronička građa] / Dražen Crčić, Jana Žiljak Gršić, Denis Jurečić. - Ilustr.
Bibliografija: 7 jed. - Abstract. - The focus of this paper is the introduction of new security elements into the authenticity of information on documents which concern the traceability of products. This article proposes dual marking using the infrared printing technology, which involves differences between the visible and infrared spectrum and separate detection of certain information with an infrared camera. Each meat product is assigned a unique designation, embedded in the document and hidden from the naked eye, in order to prevent changing, scanning or modifying with currently known techniques. A product receives a certificate with a security approval which carries information about the complete traceability of the product. A new central data registry which collects information from all necessary sources is proposed. The web portal and the accompanying database are designed to work in the cloud. The security of the exchange of data between the server and the user is ensured. The information about the traceability and the delineation between the visible and infrared hidden are approved and coordinated by the relevant authorities, breeders, distributors and sellers. The design of the entire information presents completely transparent information about the products to the end consumer.

A model for the designing of multimodal transport processes and the concept of its integration with the EPLOS system [Elektronička građa] / Mariusz Wasiak, Paweł Leleń, Michał Kłodawski, Mariusz Izdebski, Ilona Jacyna-Gołda. - Ilustr.
Bibliografija: 36 jed. - Abstract. - The paper proposes a new single criterion mathematical model for the designing of multimodal transport processes by taking into account the cargo’s susceptibility and the concept of its inclusion into the EPLOS system, which is done as part of the EUREKA initiative. This system will integrate the data from logistics sources and transport and logistics infrastructure from many sources. In the first phase of its implementation, it will cover the Czech Republic, Poland, and the Baltic States. Using the EPLOS system integrating data from various sources needed to solve this problem is a proposal to overcome the main barrier to the effective planning of multimodal transport processes – a lack of reliable information.

Benefits from implementing the EPLOS system in logistics companies [Elektronička građa] / Emilian Szczepański, Rostislav Vasek, Piotr Klimek, Mariusz Wasiak. - Ilustr.
Bibliografija: 29 jed. - Abstract. - Logistics companies are currently differently using IT tools to assist the planning of their operational activity. The functionalities of tools are also different. The paper presents the results of a research on the use of automated solutions to obtain the data necessary for logistics processes planning. It also presents a review of IT solutions used by TSL (transport, shipping, logistics) companies and the functionality of these tools. This allowed for the assessment of the potential of the EPLOS system to be used in TSL companies, as well as the benefits of implementing this system. In the paper, the selected results of a survey made in companies about the crucial data needed for efficient operating were presented. The summary indicates the main features that software should have in the era of the Industry 4.0 revolution.

An integrated EPLOS database as a tool supporting TSL companies [Elektronička građa] / Mariusz Wasiak, Michał Kłodawski, Konrad Lewczuk, Piotr Klimek, Emilian Szczepański. - Ilustr.
Bibliografija: 32 jed. - Abstract. - The paper presents the conceptual design of a database for the European Portal of Logistics Services (EPLOS) and its application. The database contains the data on logistics companies, the infrastructure for road, railway, inland, and air transport, as well as the data on the nodal elements of logistics infrastructure (warehouse facilities, seaports, transhipment terminals). Complete and verified information is the fundamental condition for rational decisions about the realization of logistics processes on a meso- and macroeconomic scale. Authors present the relations in the making of the EPLOS database, its assumed scope, and the potential benefits for the TSL market from accessing the EPLOS database.

Route planning with dynamic information from the EPLOS system [Elektronička građa] / Michał Kłodawski, Marianna Jacyna, Rostislav Vasek, Piotr Klimek, Roland Jachimowski, Emilian Szczepański, Konrad Lewczuk. - Graf. prikazi.
Bibliografija: 36 jed. - Summary. - The paper presents the problem of distribution route planning with dynamic information about sudden customers' needs. Particular attention was paid to dynamic vehicle route planning and its influence on the distance covered by a distribution vehicle. In the article, authors assume that the quick information about customers’ sudden needs is transferred from the EPLOS tool data base. Authors analyze the available literature on transport route optimization and propose a solution to the problem of distribution among customers with sudden needs. In order to present the impact of quick information influence on the distribution route minimization, a simulation model of the vehicle routing problem was generated in the FlexSim environment.

The selected problems of public transport organization using mathematical tools on the example of Poland [Elektronička građa] / Piotr Gołębiowski, Jolanta Żak, Piotr Kisielewski.
Bibliografija: 65 jed. - Abstract. - Public transport plays an increasingly important role in satisfying the transport needs. Travellers’ requirements regarding the quality of services are increasing. In addition to passenger comfort, other parameters are important (timetable and the state of transport infrastructure). Therefore, methods that determine the appropriate organization of public transport for an area should be sought. The purpose of the article is to present the most commonly used optimization methods and tools that have been applied to the chosen problems of organization of public transport mainly in Poland (described in the articles of mainly Polish scientists), but against the background of global research. The article characterizes the functioning of public transport in Poland. The selected problems of public transport functioning, which can be solved by using optimization methods and tools were discussed. The chosen methods that were used to formulate and solve the identified problems were indicated. The effects of this article will form part of the work on the POIR.01.01.01-00-0970/17-00 project "IT system for computer-aided public transport planning" financed by the National Centre for Research and Development.

Sustainable transport indicators in the context of introducing of electric passenger cars [Elektronička građa] / Stevan Kjosevski, Atanas Kochov, Darko Danev, Aleksandar Kostikj. - Graf. prikazi.
Bibliografija: 22 jed. - Summary. - Sustainable development and sustainable transport are becoming of higher and higher importance. A scientific approach to sustainable development analysis means, first of all, identification of relevant indicators. Based on literature review and regional professionals’ view, a total of 90 indicators have been chosen. They have been structured in five hierarchic levels. A total of five personal transport means alternatives have been analyzed in the research. The AHP method of analysis has been employed in which 75 professionals from the Western Balkan countries have filled appropriate questionnaire. The research presents their opinion about the capacity of each of the alternatives to contribute to the sustainable transport in the region, but also puts a light on perception of the professionals on importance of chosen indicators. The results of this research could be used for further research and could also help to decision making levels regarding sustainable transport and sustainable development.

Tourism as a factor of demand in public road passenger transportation in the Republic of Croatia [Elektronička građa] / Goran Kos, Neven Ivandić, Krešimir Vidović. - Graf. prikazi.
Bibliografija: 31 jed. - Summary. - The paper presents the results of research in tourism as one of the most important factors in the public passenger transport demand. The research has been carried out for the requirements of creating a Tourism Satellite Account (TSA) for the Republic of Croatia for 2016. Traffic and tourism, as strategic economic activities of the Republic of Croatia, have the characteristics of complex and dynamic systems, mutually conditioned by the guidelines of the demand and supply chain of tourist product values. Therefore, the paper is oriented towards the analysis of the significance of tourism for public road passenger transport in the Republic of Croatia. During 2016, road intercity passenger transport carried 50.4 million passengers, out of which 98 percent in domestic and 2 percent in international transport. Passenger road transportation is marked by mild seasonal oscillations, with the summer period marked by the lowest level of demand, and the period from January to March by the largest number of passengers. The provision of public road transportation services in 2016 realised a revenue of 1.8 billion kuna for 433 business subjects registered in this activity. The trends indicate an increase in the number of travelled kilometres by buses with passengers.

Ustroj i djelovanje Dioničarskoga društva Lonjskopoljske željeznice u periodu Austro-Ugarske Monarhije [Elektronička građa] / Siniša Lajnert. - Graf. prikazi.
Bibliografske bilješke uz tekst ; bibliografija: str. 960-963. - Sažetak ; Summary. - U radu autor na temelju arhivskih izvora, a s aspekta povijesti institucija, obrađuje ustroj i djelovanje Dioničarskoga društva Lonjskopoljske željeznice u periodu Austro-Ugarske Monarhije. Sjedište Društva, kao i većine vicinalnih željeznica, bilo je u Budimpešti. Poslove Dioničarskoga društva obavljali su glavna skupština dioničara, ravnateljstvo i nadzorni odbor. Pruge Društva bile su sljedeće: Dugo Selo – Novska i Banova Jaruga – Pakrac. Te privatne pruge bile su u državnoj eksploataciji, odnosno upravi. U Austro-Ugarskoj Monarhiji pruge Društva potpadale su pod nadležnost Poslovne uprave Kraljevskih ugarskih državnih željeznica u Zagrebu. Društvo je poslovalo s financijskim dobitkom. - In the paper the author outlines from the aspect of the history of institutions the structure and the activity of the The Lonjsko Polje Railway Stock Company during the Austro-Hungarian Monarchy. Like the majority of other vicinal railways, the company had its headquarters in Budapest. The stock company was founded on 15 June 1896. The stock company’s tasks were performed by: the stockholders’ general assembly, headquarters and the inspecting committee. The company’s railway lines were: Dugo Selo-Novska and Banova Jaruga-Pakrac. They were put into traffic on 29 November 1897. These private railway lines were exploited i.e. administrated by the state. During the Austro-Hungarian Monarchy the company’s railway lines came under the jurisdiction of the Traffic Administration of the Royal Hungarian State Railways in Zagreb. The Novska-Dugo Selo-Zagreb railway track was approximately 12.5 km shorter than Novska-Sisak-Zagreb, whose Sisak-Zagreb-Savski Marof (Zidani Most) branch was owned by the Southern Railway Society, the biggest and the most powerful railway stock company in the Monarchy. That by default made them competitors. During its construction it was decided to create a transit railway line from the former for the transitional traffic to the detriment of the Southern Railways. By analysing the published information on the business activity of the Lonjsko Polje Railway in the Austro-Hungarian Monarchy and by comparing it with other Croatian-Slavonian vicinal railways, bearing in mind its stock capital of 9.940,000 krone and its operating in the black, it can be concluded that the stock company was a respectable and successful private vicinal railway.

A strategic service management model in national gas distribution projects [Elektronička građa] / Fereidoun Esmaeilzadeh, Kazem Askarifar, Pegah Alamdari. - Graf. prikazi.
Bibliografija: 27 jed. - Abstract. - The main purpose of this research was to develop a model regarding strategic service management in order to improve the performance of projects related to the oil and gas industry. To this end, this study was conducted in two steps. Firstly, the main practices of SSM were defined by a systematic review and completed by experts’ interviews, and the data onto the expected and perceived about each practice were collected by using a questionnaire answered by the managers and direct experts of the Fars Gas Company, Iran, and its contractors in a five-year period. Finally, the SSM model was determined in a focus group. All participants were selected judgmentally and purposefully based on theoretical saturation. The findings show that the employer expects the contractor to improve the communication skills and the grooming and professional appearance of its staff and that they spend enough time processing the employer requests. As a result, the SSM model was developed based on four strategic cornerstones, including managerial attitude improvement, managing communications, improving business processes, and strengthening internal controls.

A supplier selection model emphasizing the project risk management in drug production in pharmaceutical industry [Elektronička građa] / Malek Mohammad Sabbaghi, Ahmad Allahyari. - Graf. prikazi.
Bibliografija: 33 jed. - Abstract. - Risk management is considered to be one of the main phases of project management and one of the eight main areas of the “project management body of knowledge”. The complexities involved in the drug production projects on the one hand, and the need for risk assessment and management in such projects on the other hand, make this issue completely clear. According to the risk mitigation strategies in project management and using the academic professors and experts in the field of drug production and pharmaceutical projects, the present study aimed to provide a checklist for selecting supplier in the drug production projects. This was done using the main eight and 30 secondary indicators related to the top supplier selection and four main and nine secondary indicators related to influencing environmental risks. Finally, after reviewing the statistical results obtained from the questionnaires and utilizing the TOPSIS technique, seven main indicators including “quality, flexibility, delivery, technology, information and communication systems, cost and experience” along with 24 secondary indicators were obtained relating to the top supplier selection. Also, the delivery factors group was identified as the most important group based on the Friedman test results.

Competencies of production in SMEs in assembly industries in a digital, volatile business environment [Elektronička građa] / Maria Hulla, Christian Ramsauer. - Graf. prikazi.
Bibliografija: 66 jed. - Abstract. - SMEs are currently confronted with major challenges such as increasing uncertainty and volatility. In order to face these challenges, agility and digitalization can be implemented. Both concepts bring about numerous opportunities and new competency requirements. Currently, there are few scientifically based, practical training courses that focus on digitization and/or agility. The aim of this paper is to provide a roadmap for the development of the training concept. In this training, participants will be able to acquire theoretical content on a learning platform in a flexible way and they will be able to apply this knowledge in a learning factory. Based on a literature overview, requirements for such a training and the necessary skills in a digital, volatile business environment will be given.

CRM adoption factors in the gaming industry [Elektronička građa] / Armand Faganel, Mitja Constantini. - Graf. prikazi.
Bibliografija: 47 jed. - Summary ; Sažetak. - The aim of this paper is to evaluate critical success factors and investigate the benefits that might be gained by adopting Customer Relationship Management (CRM) in the gaming industry from the perspective of individuals involved in the process of adopting the CRM. A total number of 109 casinos’ managers from all over the world have been surveyed about the factors’ importance for the CRM adoption. Based on the multiple regression and ANOVA analysis, an estimated function of the influence of the most important umbrella factors – human, project and technological, for the success of CRM project in a company has been formulated. The highest rated elements in successful cases of CRM adoption are almost entirely bound to human factor. CRM systems are estimated to evolve further into a direction of individual customer experience management and become more and more intelligent, integrated and data-driven. - Cilj ovog rada je vrednovati ključne kritične čimbenike uspjeha i analizirati koristi, koje bi industrija igara na sreću mogla dobiti od uvođenja upravljanja odnosima s kupcima (Customer Relationship Management – CRM), i to iz perspektive pojedinaca, koji su uključeni u proces prihvaćanja CRM-a. Ukupno je anketirano 109 menadžera kasina iz cijelog svijeta, na temu značaja čimbenika prihvaćanja CRM-a. Na temelju provedene multiple regresije i ANOVA analize, procjenjuje se funkcija najznačajnijih općih čimbenika za uspješnost prihvaćanja CRM-a, i to - ljudskih, projektnih i tehnoloških. Najpozitivnije procijenjeni čimbenici u uspješnim slučajevima prihvaćanja CRM-a su gotovo isključivo povezani s elementom ljudi. Za same se sustave CRM-a procjenjuje da će se dalje razvijati u smjeru upravljanja individualnim doživljajima kupca, kao i da će postajati sve inteligentniji, integrirani i vođeni podacima.

Društveno poduzetništvo [Elektronička građa] : glavne odrednice i prikaz slučaja / Petar Šajfar, Lorena Strmota.
Bilješke uz tekst. - Bibliografija: 33 jed. - Sažetak ; Summary. - Profitno orijentiran sustav, kao dominantna paradigma, generira brojne probleme u društvenoj sferi, posebice kada je riječ o ranjivim društvenim skupinama među koje spadaju osobe s invaliditetom. Postoje brojni odgovori na navedeno stanje, a jedan od njih je društveno poduzetništvo koje teži integraciji ekonomskih i socijalnih ciljeva čime se smješta na razmeđe profitnog i neprofitnog sektora. Iako svoje korijenje vuče iz 18. stoljeća, u zadnjim desetljećima, a posebice u doba krize, ponovo se aktualizira i intenzivno proučava. Cilj je rada pružiti najvažnije informacije potrebne za razumijevanje koncepta društvenog poduzetništva. Navedeno će se nastojati postići kroz prikaz povijesnog pregleda razvoja koncepta društvenog poduzetništva, definicija te prikaz institucionalnog i normativnog okvira, s naglaskom na hrvatski kontekst. Naposljetku se daje primjer društvenog poduzeća u razvoju te zaključna razmatranja temeljena na ranijim prikazima. - The profit-oriented system as the dominant paradigm, in addition to all its benefits, generates numerous problems in society. It is especially significant in terms of vulnerable groups such as people with disabilities. Social entrepreneurship could be a model that contributes to combating social problems. It integrates social and economic goals and takes place between profit and non-profit sectors. Social entrepreneurship has rooted in the 18th century, but in recent decades, it has been actualized and studied intensively, especially during periods of economic crisis. The purpose of this paper is to provide crucial information about social entrepreneurship. Considering that, the paper consists of chapters about historical development and definitions of social entrepreneurship, institutional and normative framework, especially in the Croatian context, an example of social entrepreneur and conclusion.

Franšiza - model za razvoj poduzetništva [Elektronička građa] / Aleksandar Erceg, Ivana Orban. - Graf. prikazi.
Bibliografija: 24 jed. - Sažetak ; Summary. - Prilikom pokretanja poslovnog pothvata potrebno je imati razrađenu strategiju poslovanja u kojoj se poduzetnici, između ostalog, bave i problemom nedovoljne popularnosti njihovih usluga. Jedan od načina pokretanja poduzetničkog pothvata je i kupovina franšize. Ulaskom u franšizni odnos poduzetnik na samom početku poslovanja može zaobići „početničke“ probleme i premostiti poslovne prepreke s obzirom na to da davatelj franšize nudi dokazanu strategiju i metodologiju poslovanja kao i potrebno znanje. Rad obrađuje pokretanje poduzetničkog pothvata kroz kupovinu franšize. Obrađuje se franšizni odnos te prednosti i nedostatke ove vrste poduzetničke alternative za uključene strane te proces kupovine franšize s potrebnim koracima. Kupnja franšizne praonice rublja istražena je u kontekstu prednosti koju ovakva vrsta poslovanja ima u odnosu na samostalno pokretanje poslovnog pothvata nekoga tko nema predznanje u predmetnoj industriji. U radu su opisani koraci kupnje franšize na temelju prijedloga poslovne suradnje dobivenog od jednog svjetskog franšiznog brenda. U cilju analize potencijalnih rizika pokretanja poslovanja napravljena je analize isplativosti, a oni se u najvećoj mjeri odnose na činjenicu da razvoj uslužnih franšiza, između ostalog, ovisi i o promjenama u društvenim navikama i stavovima. Rezultati provedenog istraživanja rada može biti korisno svim pojedincima koji razmišljaju o pokretanju poslovnog pothvata putem kupnje franšize. - When starting a business venture, it is necessary to have an elaborate business strategy in which entrepreneurs, among other things, deal with the problem of scarce popularity of their services. One way to start an entrepreneurial venture is to buy a franchise. By entering a franchise relationship, at the very beginning of the business, the entrepreneur can avoid "beginner" problems and overcome business obstacles, given that the franchisor offers a proven business strategy and methodology as well as the necessary knowledge. The paper deals with starting an entrepreneurial venture through the purchase of a franchise. The paper discusses a franchise relationship and the advantages and disadvantages of this type of entrepreneurial alternative for the parties involved. It also observes the process of buying a franchise together with the necessary steps. The purchase of a laundry franchise has been explored in the context of the advantage that this type of business has over starting a business venture by someone who has no prior knowledge in this particular industry. The paper describes the steps of buying a franchise based on a business cooperation proposal received from a global franchise brand. In order to analyze the potential risks of starting a business, cost-effectiveness analyses were made, and they are mostly related to the fact that the development of service franchises, among other things, depends on changes in social habits and attitudes. The results of the conducted research work can be useful to all individuals who are considering starting a business venture through the purchase of a franchise.

Identification and prioritization of employee satisfaction strategies in Tehran Regional Water Company using analytic hierarchy process (AHP) [Elektronička građa] / Nasim Bonyadi, Hormat Asghari, Mojtaba Kiaei. - Graf. prikazi.
Bibliografija: 26 jed. - Abstract. - Employee satisfaction is one of the main indicators of attitudes assessment in organizations and is one of the factors which can be used to assess the status of an organization. This is important because of the role that this construct plays in improvement of the organization and the workforce. Organizationally, a high level of job satisfaction reflects a highly desirable organizational climate which leads to recruitment and retention of employees and increases efficiency and effectiveness. Accordingly, this study tended to identify and prioritize employee satisfaction strategies in Tehran's Regional Water Company using analytic hierarchy process (AHP). The data was analyzed using AHP method by Expert Choice software. The statistical population included 16 experts in human sciences and in management science working in the Tehran Regional Water Company. Due to the limited number of statistical population, sampling was not used and census method was used; that is, all people in the statistical population participated in the study. Prioritization of the criteria showed that organizational strategies are the most important, followed by organizational policies and organizational achievements. Sub-criteria of these criteria were also prioritized.

The indirect verification of the going concern assumption by analysing the threat of bankruptcy [Elektronička građa] / Michal Karas, Mária Režňáková. - Graf. prikazi.
Bibliografija: 59 jed. - Summary ; Sažetak. - The generally accepted aim of doing business is to maximize the business value. The value of a business strongly depends on its ability to generate future cash flow for its owners. A necessary condition is that the business remains financially viable or in other words, the business should meet the assumption of going concern principle. Verifying such an assumption, however, remains an issue. We suggest that this could be indirectly verified as an absence of threat of imminent financial distress. For this purpose, we analysed a set of cash flow and profit based ratios along with a set of other ratios with a potential influence on the business value. In terms of sample, we focus on Czech manufacturing SMEs that were selected, due to their specific features resulting from the financial constraints. The F-test and t-test were employed as a method of identifying the typical signs of risk of financial distress or rather obstacles in accepting the going concern principle. We found that only four of the analysed ratios could serve effectively for this purpose. The best results were achieved when employing ratios describing the operational cash flow or short-term debt, where the gap between viable business and those with limited prospects is the widest. - Opće prihvaćeni cilj poslovanja je maksimiziranje vrijednosti poduzeća, koja značajno ovisi o sposobnosti za stvaranje budućih tijekova novca za vlasnike. Pritom se podrazumijeva uvjet financijske održivosti poduzeća, odnosno ispunjavanje pretpostavke trajnosti poslovanja. Ipak, verifikacija navedene pretpostavke ostaje i dalje otvoreno pitanje. Smatramo da se isto može riješiti indirektnom verifikacijom, koja podrazumijeva nepostojanje prijetnje bliske financijske krize. U tu smo svrhu analizirali skupinu pokazatelja, zasnovanih na novčanom tijeku i dobiti, zajedno sa skupinom drugih pokazatelja, s potencijalnim djelovanjem na vrijednost poduzeća. Koncentriramo se na uzorak malih i srednjih proizvodnih poduzeća u Češkoj, a koja su izabrana, s obzirom na specifična obilježja, povezana s financijskim ograničenjima. Za identifikaciju tipičnih znakova rizika financijskih poteškoća, odnosno nepoštovanja pretpostavke trajnosti poslovanja, koriste se F- i t-test. Za efikasno korištenje u navedene svrhe, pozitivno smo vrednovali samo četiri od analiziranih pokazatelja. Najbolji se rezultati dobivaju korištenjem indikatora, koji opisuju operativni novčani tijek ili kratkoročni dug, kod kojih se javljaju najveće razlike između održivih poduzeća i onih s ograničenim perspektivama.

Industry 4.0 readiness assessment [Elektronička građa] : comparison of tools and introduction of new tool for SME / Bernhard Axmann, Harmoko Harmoko. - Graf. prikazi.
Bibliografija: 19 jed. - Abstract. - This research aims to establish an assessment tool for assessing the readiness of small and medium enterprises (SME) in industry 4.0. The assessment of the current and future status is crucial for companies to decide on the right strategy and actions on the road to a digital company. First will be compared existing tools such as: IMPULS (VDMA), PwC and Uni-Warwick. On that basis, a tool for SME will be introduce. The tool has 12 categories: data sharing, data storage, data quality, data processing, product design and development, smart material planning, smart production, smart maintenance, smart logistic, IT security, machines readiness and communication between machines. Those categories are grouped into three: data, software and hardware. Each category has five levels of readiness (from 1 to 5), with particular criteria that refer to literature studies and expert’s opinion.

Integration of tactical aspects into strategic production network planning [Elektronička građa] / Elias Auberger, Christian Ramsauer. - Graf. prikazi.
Bibliografija: 41 jed. - Abstract. - Nowadays, production companies are facing an increasingly volatile environment. Due to increasing globalization, but also de-globalization, taking into consideration an internal production network is becoming more and more important for companies, all in order to be able to counteract in an agile way the uncertainties such as swings in the demand. Current production network planning procedures focus on (re-)locating decisions without delving into what happens inside the plants, neglecting the dynamics of production networks, following a rigid top-down approach during the configuration phase, and they do not integrate the effects of planning tasks at the factory level (tactical and operational planning). In order to be able to make strategic decisions with a well-founded database regarding the production network, the effects on the tactical and operational level must be considered in an iterative way during the strategic decision-making process. The aim of this research is to define the requirements for an approach to strategic production network planning, which considers the effects at the tactical and operational level in an iterative way, and to develop a process model, derived from the requirements, that in its five phases considers the deficiencies of the existing approaches.

VINŠALEK Stipić, Valentina
Korporativno upravljanje i ekonomija trećeg puta [Elektronička građa] Valentina Vinšalek Stipić. - Graf. prikazi.
Bibliografija: 14 jed. - Sažetak ; Summary. - Suvremeno globalno okruženje zahtijeva od korporativnog menadžmenta primjenu novih način upravljanja radi ostvarivanja i zadržavanja konkurentske prednosti. Sve interesne skupine moraju imati zajednički cilj kako bi se ostvarilo opće zadovoljstvo. Poduzećima ne smije više jedini cilj biti ostvarivanje profita, nego i boljitak društva u cjelini. Iz navedenih se razloga zagovara koncept ekonomije trećeg puta. Ekonomija trećeg puta u prvi plan stavlja socijalnu osjetljivost prema široj društvenoj zajednici. To ne podrazumijeva socijalno pomaganje pojedincima, nego stvaranje uvjeta za postizanje veće pravičnosti u pogledu socijalne i ekonomske osjetljivosti, društveno odgovornim poslovanjem i zaštite životne sredine. Nekada su ostvarena visina profita i tržišnog udjela bili jedino mjerilo uspješnosti poslovanja i dobre pozicije poduzeća na tržištu. Međutim u današnje se vrijeme od poduzeća traži ekološka i socijalna osviještenost što se smatra osnovnim problemom modernog kapitalizma. U skladu s navedenim cilj istraživanja u ovom radu bio je dobiti saznanja pridaju li i u kolikoj mjeri Hrvatska poduzeća važnost socijalnoj osjetljivosti prema svojim zaposlenicima te koliko su izdavanja za socijalna prava radnika povezana sa ostvarivanjem neto profitne marže poduzeća. Istraživanje je provedeno na uzorku od 53 poduzeća koja su registrirana i posluju na području Republike Hrvatske. Empirijskim istraživanjem primjenom matematičkih i statističkih metoda (korelacije i regresije) došlo se do zaključka kako su poduzeća svjesna važnosti socijalne osjetljivosti prema svojim zaposlenicima te takvu poslovnu politiku implementiraju u svoje poslovne strategije. Međutim, došlo se do saznanja kako poduzeća iz promatranog uzorka u dovoljnoj mjeri ne financiraju socijalna prava svojih zaposlenika. Postoji pozitivna linearna povezanost s ostvarivanjem neto profitne marže, dok je koeficijent korelacije izrazito mali. - The contemporary global environment requires corporate management to apply new ways of managing it to achieve and maintain a competitive advantage. All stakeholders must have a common goal to achieve universal satisfaction. Businesses should no longer have the sole goal of making a profit, but the prosperity of society as a whole. That is the reason for the advocacy of the economy of the third way. The economy of the third way puts social sensitivity for the wider community first. This does not entail social assistance to individuals but the creation of conditions for greater equity in terms of social and economic sensitivity, socially responsible business operations and environmental protection. Some time ago, profit and market share were the only measure of business success and good position of companies in the market. However, businesses are required to have environmental and social awareness, which is considered to be a major problem in modern capitalism. In this paper, it was necessary to find out how much importance Croatian companies give to social sensitivity towards their employees, and how much expenditures for the social rights of workers are related to the net profit margin. The survey was conducted on a sample of 53 companies registered and operating in the Republic of Croatia. Empirical research using mathematical and statistical methods (correlations and regressions) concluded that companies are aware of the importance of social sensitivity to their employees and implement such business policies in their business strategies. However, it was noticed that the companies in the sample do not sufficiently finance the social rights of their employees. There is a positive linear relationship with the realization of the net profit margin, while the correlation coefficient is extremely small.

Management of business risk hedging in construction contracts from the perspective of public investors [Elektronička građa] / Barbara Andrlova, Jana Korytarova. - Graf. prikazi.
Bibliografija: 22 jed. - Abstract. - Risk management of construction projects presented in the article focuses on the management of business risk from the perspective of public investors in public works contracts in the Czech Republic. Based on the data analysis and a comparative study of specific attributes in contracts for works, the result of the research has been a portfolio of specific instruments and their recommended parameters for effective business risk management. Qualitative analysis was conducted using a questionnaire survey and structured interviews with public sector representatives to share their views on the current practice of protecting public procurement with regard to mitigate business risk. Types, functions and recommended parameters of hedging instruments has been proposed. Effective forms of hedging are mainly liability insurance for damage to things, property and health, contractual penalties, retention money and bank guarantees. Results of the research were compared with foreign practice and international contractual standards.

Odnos upravljanja radnom uspješnošću i kompenzacijskog menadžmenta u velikim poduzećima u Republici Hrvatskoj [Elektronička građa] / Vinko Mostarac, Danijel Knežević, Ivan Budimir. - Graf. prikazi.
Bibliografija: 13 jed. - Sažetak ; Summary. - U suvremenim poduzećima jedan je od glavnih izazova pronaći način kako motivirati i zadržati kvalitetne zaposlenike. Kako bi se u tome uistinu i uspjelo, poduzeća kontinuirano prate radnu uspješnost zaposlenika, a na temelju toga uvode i primjenjuju određene elemente sustava nagrađivanja. Glavni cilj ovog rada je istražiti sustav upravljanja radnom uspješnošću i koncept kompenzacijskog menadžmenta te njihov odnos u velikim poduzećima u Republici Hrvatskoj. U tu svrhu je provedeno anketno istraživanje na uzorku zaposlenika u velikim poduzećima u Republici Hrvatskoj. Nalazi istraživanja ukazuju na relevantnost i potrebu za daljnjim kontinuiranim razvojem i povezivanjem sustava praćenja radne uspješnosti i kompenzacijskog menadžmenta u poduzećima. - In modern companies, one of the main challenges is finding a way to motivate and retain quality employees. In order to truly achieve this goal, companies continuously monitor employees’ work performance and, on that basis, introduce and apply certain elements of a reward system. The main objective of this paper is to explore the performance management system and the concept of compensation management and ultimately their relationship in large companies in the Republic of Croatia. For this purpose, a survey was conducted on the sample of employees in large companies in the Republic of Croatia. The findings of the research imply the relevance and requisite for further continuous development and integration of a performance management system and compensation management in companies.

Poslovni modeli nakon Covid-19 [Elektronička građa] : postati bolji i uspješniji / Ivica Katavić, Vedrana Šimunić Rod, Barbara Konjevod. - Graf. prikazi.
Bibliografija: 22 jed. - Sažetak ; Summary. - U odgovoru na korona virus, vlade zemalja poduzimaju značajne intervencije u stabiliziranju gospodarstva, a poduzeća se pokušavaju prilagoditi promjenjivim potrebama svojih zaposlenika, kupaca i dobavljača. Poslovne aktivnosti se usporavaju i ne mogu se predvidjeti posljedice korona virusa. Međutim, jedna pozitivna stvar uzrokovana COVID-19 krizom je da su poslovni subjekti prisiljeni inovirati i analizirati načine poslovanja. Stoga je glavni cilj istraživanja bio utvrditi kako transformirati poslovne modele koji će omogućiti kreiranje novih vrijednosti za poslovne subjekte, kupce i društvo u cjelini nakon globalne pandemije uzrokovane virusom COVID – 19. Istraživanje se temeljilo na kvalitativnim podacima prikupljenim analizom relevantnih sadržaja. Rezultati istraživanja pokazuju da će karakteristike poslovnih modela biti više fleksibilne (planiranje radne snage za rad na daljinu, fleksibilni ugovori s kupcima i dobavljačima, nova politika zapošljavanja), usmjerene na planiranje postupaka za ograničenje rizika i reakcija na krizne situacije, te će IT infrastruktura biti sigurnija, kao i zaštita i sigurnost ljudi. Nakon COVID-19 krize poslovni svijet će izgledati drugačije. U početku kaotično, no povijest pokazuje da tržišta i društvo postaju bolja i jača nakon globalnih kriza. - In response to the corona virus, governments are making significant interventions to stabilize the economy, and companies are adapting rapidly to the changing needs of their employees, customers, and suppliers. Business activities are slowing down and the consequences of coronavirus cannot be predicted. However, one positive thing caused by the COVID-19 crisis is that businesses are forced to innovate and analyze ways of doing business. Therefore, the main goal of this paper was to determine how to transform new business models that will enable the creation of new values for businesses, customers and society as a whole after the global pandemic caused by the COVID - 19 virus. The research was based on qualitative data collected by analysis of relevant content. The results of the research show that the characteristics of business models will be more flexible (remote workforce planning, flexible contracts with customers and suppliers, new employment policy), focused on planning procedures for risk mitigation and crisis response, and IT infrastructure will be safer, as well as the protection and safety of people. After the COVID-19 crisis, the business world will look different. Initially, it will appear chaotic, but the history shows that markets and society are getting better and stronger after the global crises.

Prevencija ili evidencija [Elektronička građa] : prepoznati rane simptome krize ili evidentirati gubitke u poslovanju? / Žarko Kruljac, Danijel Knežević. - Graf. prikazi.
Bibliografija: 36 jed. - Sažetak ; Summary. - Aktualnost istraživanja područja kriznog menadžmenta posebno je izražena zadnjih 20 godina u kojima se, između ostaloga, dogodila svjetska ekonomska kriza, a zatim i trenutačna gospodarska kriza uzrokovana proglašenjem globalne pandemije zbog pojave bolesti COVID-19. Nadalje, tržište je postalo globalno, poslovanje digitaliziranije, razvija se umjetna inteligencija, robotiziraju se procesi, itd. Može se zaključiti da su suvremeni uvjeti poslovanja kompleksni i dinamični s čime su i razlozi za potencijalni nastanak krize u poduzeću sve brojniji. Menadžeri u praksi često reagiraju na simptome krize koji se u pokazateljima boniteta i bilančnim pokazateljima u literaturi opisuju kao rani simptomi. Autori smatraju da takav način upravljanja krizom nije učinkovit jer se navedeni pokazatelji mogu definirati kao mjera razine krize u poduzeću, a ne kao rani simptomi krize. Adekvatan način prevencije krize prepoznavanje je ranih simptoma krize putem upravljanja poslovnim procesima. U literaturi je dokazano da je najveći broj kriza prouzročen unutrašnjim čimbenicima, a upravljanjem poslovnim procesima se te neusklađenosti rješavaju. Cilj rada je raspraviti i problematizirati trenutak prepoznavanja potencijalne krize u poduzeću, evidenciju iste, reakcije menadžera kao i ukazati na potencijalne mogućnosti i načine prevencije krize koje se posebno ogledaju u upravljanju poslovnim procesima. U radu se nakon uvoda objašnjavaju pojam i uzroci krize, rani simptomi krize kao I krizni menadžment i upravljanje poslovnim procesima. Na kraju rada je zaključak. - The research in the field of crisis management has become particularly relevant in the last two decades in which, among other things, the global economic crisis occurred, followed by the current economic crisis caused by the declaration of COVID-19 global pandemic. Furthermore, the market has become global, business increasingly digitalized, artificial intelligence is evolving, processes are being robotized, etc. We can conclude that modern business conditions are complex and dynamic, which is why there are many causes of a potential crisis in a company. In practice, managers often react to signs of a crisis which are, in solvency indicators and balance sheet indicators in reference books, described as early signs. The authors believe that such crisis management way is not efficient because the indicators can be defined as the measure of the crisis level in the company and not as early signs of a crisis. An adequate way to prevent a crisis is to recognize the early signs of it through business process management. Reference books prove that most crises are caused by internal factors and business process management solves those inconsistencies. The paper aims to discuss the moment of recognizing a potential crisis in a company, recording it, reactions of managers, as well as point out potential opportunities and ways to prevent a crisis, which are especially reflected in business process management. After the introduction, the paper explains the concept and causes of a crisis, the early signs of a crisis as well as crisis management and business process management. The paper ends with a conclusion.

The role of benefits in sustaining HRM outcomes [Elektronička građa] : an empirical research study / Lovorka Galetić, Maja Klindžić. - Graf. prikazi.
Bibliografske bilješke uz tekst ; bibliografija: 39 jed. - Summary ; Sažetak. - Benefits are a type of indirect compensation that aims to achieve many goals. Primarily, however, companies provide benefits to prove that they care for their employees’ personal needs, or because they wish to offer an attractive and competitive total compensation package. Since benefits account for a growing portion of the total compensation package costs, and taking into account that the motivating potential of benefits has lately been brought into question, we aim to analyze the role of benefits in achieving primary goals of human resource management, i.e., attracting, retaining and engaging employees in Croatian companies. Therefore, an empirical study was conducted on a sample of Croatian companies, which shows security, pension and health benefits, which are usually highly valued by employees, are under-represented in Croatian companies. In the case of administrative and manual employees, social activities, non-mandatory health and pension insurance and work from home were positively related to retention. However, statistically significant relationships between benefits mostly related to work-life balance and HR-related outcomes were almost exclusively negative in the case of experts, while only non-mandatory health insurance was found to be potentially useful in engaging and retaining experts. Therefore, employers should redesign benefits strategy and consider offering a flexible benefits system as an option. - Beneficije su oblik indirektnih kompenzacija, koji pokušava postići mnoge ciljeve. Međutim, poduzeća primarno pružaju beneficije, kako bi dokazala da brinu za osobne potrebe zaposlenika, ili žele ponuditi atraktivan i konkurentan ukupni paket kompenzacija. S obzirom da beneficije predstavljaju rastući dio ukupnih troškova kompenzacija te uzevši u obzir da se odnedavno propituje njihov motivacijski potencijal, potrebno je analizirati ulogu beneficija u postizanju primarnih ciljeva upravljanja ljudskim potencijalima (privlačenju, zadržavanju i angažmanu zaposlenika) u hrvatskim poduzećima. Stoga je provedena empirijska studija na uzorku hrvatskih poduzeća, koja pokazuje da su sigurnost te mirovinske i zdravstvene beneficije nedovoljno zastupljene u hrvatskim poduzećima, iako ih zaposlenici obično visoko cijene. Kod administrativnih i proizvodnih radnika, socijalne aktivnosti, dobrovoljno zdravstveno i mirovinsko osiguranje te mogućnost rada od kuće su pozitivno povezani sa zadržavanjem zaposlenika. Međutim, statistički značajne povezanosti između beneficija, uglavnom orijentiranih na održavanje ravnoteže između radnog i osobnog života, te ishoda upravljanja ljudskim resursima, za eksperte su bile gotovo uvijek negativno. Samo se dobrovoljno zdravstveno osiguranje pokazalo kao potencijalno korisno za angažiranje i zadržavanje eksperata. Stoga bi poslodavci trebali redizajnirati strategiju beneficija i promisliti o opcionalnoj ponudi fleksibilnog sustava beneficija.

Selection of an optimal supplier [Elektronička građa] / Predrag Ćosić, Zdenka Keran, Vedran Kokot. - Graf. prikazi.
Bibliografija: 10 jed. - Abstract. - The paper describes the selection of an optimal supplier from China based on three obtained bids to produce 120,000 forged pieces, which is the primary process for shaft production. The choice was made using the AHP method based on the Expert Choice software program and Multiple-Criteria Decision-Making (MCDM). The key information when choosing the optimal supplier of large number of forgings is to define the objective of the task, decision tree with weighted criteria and sub-criteria, consistency checking and possible reconsideration using brain storming when defining the strength of criteria/sub-criteria. To some extent, this may reduce initial subjectivity in the decision-making process in the Decision Support System.

Six Sigma project for reducing manual handling of materials in real manufacturing company [Elektronička građa] : case study / Atanas Kochov, Aleksandar Argilovski. - Graf. prikazi.
Bibliografija: 5 jed. - Summary. - This paper presents a case study that is focusing on the improvement of the process of materials handling in real manufacturing company. Before the implementation of this project, the company was in a concerning state of incidents and learning events towards the ergonomics, health and safety of the operators who manually handled materials as part of their daily activities. It was proposed to use the Six Sigma framework in order to improve the process or design new process for performing the task that included manual handling of materials. In this study, through selecting suitable Six Sigma framework, mapping the current process, setting key performance indicators and using various design tools and techniques, process improvement is proposed; it will solve the problem, increase ergonomics and safety, but also increase the speed of the process and reduce the cost of spilled materials that were manually handled.

Transformation of cognitive assistance systems into augmented reality [Elektronička građa] Matthias Eder, Atacan Ketenci, Christian Ramsauer. - Ilustr.
Bibliografija: 41 jed. - Abstract. - The field of Augmented Reality (AR) has received increasing attention in recent years, as AR can be applied to a wide range of problems. The use of AR offers great potential, especially in the industrial sector. Among many applications in this area, one promising application is the augmentation of cognitive assistance systems. Much research has already been done on the development of augmented support systems but it is still lacking on how to transform existing assistance systems into an AR application. This paper focuses on this transformation and presents a process model that intends to support the migration or digitalization of existing support systems into an AR application. An experimental study validates the proposed approach and derives recommendations for action.

Tržište i grad [Elektronička građa] : simbioza poduzeća i općine u Jugoslaviji na primjeru Građevnog kombinata Međimurje - Čakovec (1963.-1981.) / Saša Vejzagić. - Graf. prikazi.
Bilješke uz tekst. - Bibliografija: str. 147-148. - Sažetak ; Summary. - Članak prati ekspanziju Građevnog kombinata Međimurje iz Čakovca od njegova nastanka u 1960-ima do vrhunca svog poslovnog razvoja na samom kraju 1970-ih. S jedne strane članak predstavlja zanimljivu povijest tehnokracije, poduzetništva i poslovnog razvoja u vrijeme deregulirane planske ekonomije. S druge priča o modernizacijskom iskustvu jugoslavenske agrarne periferije i provincijalnog grada na samim marginama političkog interesa Beograda i Zagreba. Ovo istraživanje, između ostalog, ističe najvažnije karakteristike stvaranja velikih poslovnih sustava u samoupravljanju, a istovremeno proučava odnose i interakciju između poslovne i političke domene na lokalnoj razini. Također posredno preispituje uspjeh tržišne reforme u Jugoslaviji i istražuje odnose između poduzeća i Partije. - The article traces the expansion of a Čakovec-based construction enterprise Građevni kombinat Međimurje from its formation in the 1960s until it reached the peak of its business growth at the very end of the 1970s. On one hand, it is a compelling history of technocracy, entrepreneurship, and business development in a deregulated semi-planned economy. On the other, it is the story of the modernisation of Yugoslav agricultural periphery and the transformative experience of a provincial city on the fringes of Belgrade’s or Zagreb’s political interests. Among other things, the research underlines some of the most relevant characteristics related to the formation of large business systems in self-management. It scrutinises the relations and interactions between business and politics on a local level. Indirectly, the article questions the success of the market reform in Yugoslavia and seeks the boundary between the company and the Party.

Zadovoljstvo klijenata pruženom uslugom ljekarnika u vrijeme epidemije bolesti COVID-19 [Elektronička građa] / Dora Rašan, Suzana Marković, Jelena Dorčić, Lovro Rašan. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Sažetak ; Abstract. - Uvod: Pojavom epidemije bolesti COVID-19 ljekarne su se susrele s dosad nezabilježenom potražnjom za dezinficijensima, antisepticima te zaštitnim maskama. Ljudi su u većoj mjeri počeli odlaziti u ljekarne, koje su se morale od početka epidemije strogo pridržavati mjera sigurnosti. Uloga ljekarnika u navedenim okolnostima postala je još važnija. Cilj i metode: Cilj ovog rada bio je istražiti i analizirati stavove klijenata ljekarni o kvaliteti usluge, analizirati njihovo sveukupno zadovoljstvo te ispitati razinu straha od bolesti COVID-19. U tu svrhu na temelju relevantne znanstvene literature kreiran je upitnik koji je distribuiran putem interneta. U mjerenju kvalitete usluge ljekarnika primijenjen je modificirani mjerni instrument SERVQUAL. Istraživanje je provedeno na uzorku od 203 klijenata ljekarni. Rezultati: Rezultatima provedenoga empirijskog istraživanja utvrđeno je da ispitanici posjeduju visoka očekivanja o kvaliteti usluga ljekarnika (3,93). Ukupna percepcija ispitanika pružene usluge ljekarnika iznosi 3,54, što ukazuje na činjenicu da je prisutan negativan SERVQUAL jaz između percepcije i očekivanja ispitanika (–0,39). Negativan jaz bio je najveći pri ocjeni varijable „Ljekarnik bi me trebao uputiti što učiniti ako propustim dozu lijeka”(–1,60), a najveći pozitivan jaz pri vrednovanju varijable „Ljekarnik je riješio sve zdravstvene probleme koje sam očekivao” (+0,82). Ispitanici su bili zadovoljni ukupnom pruženom uslugom ljekarnika (4,53) te su prilikom posjeta ljekarni osjećali srednju razinu straha od bolesti COVID-19 (3,03). Zaključak: Istraživanje zadovoljstva klijenata pruženom uslugom ljekarnika od krucijalnog je značaja za poboljšanja i unaprjeđenja postojeće kvalitete usluge ljekarnika. Istraživanje je pokazalo da je SERVQUAL prikladan mjerni instrument za mjerenje razlike u očekivanjima i percepciji klijenata o kvaliteti usluga ljekarnika. - Introduction: With the outbreak of the epidemic COVID-19, pharmacies encountered unprecedented demand for disinfectants, antiseptics and protective masks. More and more people went to pharmacies, which had to strictly adhere to safety measures since the beginning of the epidemic. The role of the pharmacist became even more important under the circumstances mentioned above. Objectives and methods: The aim of this study was to investigate and analyze the attitudes of pharmacy customers towards service quality, to analyze their overall satisfaction and to investigate the level of fear of the COVID-19 virus. For this purpose, a questionnaire was prepared on the basis of the relevant scientific literature and distributed online. A modified SERVQUAL model was used to measure the quality of the pharmacist’sservice. The survey was conducted on a sample of 203 pharmacy customers. Results: The results of the empirical research indicates that the respondents have high expectations of the service quality provided by pharmacists (3.93). The respondents’ overall perception of the service provided by the pharmacist is 3.54, which indicates that there is a negative SERVQUAL gap between the perception and the expectation of the respondents (-0.39). The negative gap was largest in the evaluation of the variable “Pharmacist should tell me what to do if I miss a dose of the drug” (-1.60), and the largest positive gap in the evaluation of the variable “Pharmacist has solved all the health problems I expected” (+0.82).

A comparison of "neural networks and multiple linear regressions" models to describe the rejection of micropollutants by membranes [Elektronička građa] / Yamina Ammi, Latifa Khaouane, Salah Hanini. - Graf. prikazi.
Bibliografija: 53 jed. - Summary ; Sažetak. - A rejection process of organic compounds by nanofiltration and reverse osmosis membranes was modelled using the artificial neural networks. Three feed-forward neural networks based on quantitative structure-activity relationship (QSAR-NN models) characterised by a similar structure (twelve neurons for QSAR-NN1, QSAR-NN2, and QSAR-NN3 in the input layer, one hidden layer and one neuron in the output layer), were constructed with the aim of predicting the rejection of organic compounds. A set of 1394 data points for QSAR-NN1, 980 data points for QSAR-NN2, and 436 data points for QSAR-NN3 were used to construct the neural networks. Good agreements between the predicted and experimental rejections were obtained by QSAR-NN models (the correlation coefficient for the total dataset were 0.9191 for QSAR-NN1, 0.9338 for QSAR-NN2, and 0.9709 for QSAR-NN3). Comparison between the feed-forward neural networks and multiple linear regressions based on quantitative structure-activity relationship “QSAR-MLR” revealed the superiority of the QSAR-NN models (the root mean squared errors for the total dataset for the QSAR-NN models were 10.6517 % for QSAR-NN1, 9.1991 % for QSAR-NN2, and 5.8869 % for QSAR-NN3, and for QSAR-MLR models they were 20.1865 % for QSAR-MLR1, 19.3815 % for QSAR-MLR2, and 16.2062 % for QSAR-MLR3). - Postupak odbacivanja organskih spojeva nanofiltracijom i membranama reverzne osmoze modeliran je umjetnim neuronskim mrežama. Konstruirane su tri neuronske mreže zasnovane na kvantitativnom odnosu strukture-aktivnosti (QSAR-NN modeli) karakterizirane sličnom strukturom (dvanaest neurona za QSAR-NN1, QSAR-NN2 i QSAR-NN3 u ulaznom sloju, jedan skriveni sloj i jedan neuron u izlaznom sloju), s ciljem predviđanja odbacivanja organskih spojeva. Za izgradnju neuronskih mreža upotrijebljeni su skupovi od 1394 podatkovnih točaka za QSAR-NN1, 980 podatkovnih točaka za QSAR-NN2 i 436 podatkovnih točaka za QSAR-NN3. Dobre usklađenosti između predviđenih i eksperimentalnih odbacivanja dobivene su modelima QSAR-NN (korelacijski koeficijent za ukupni skup podataka bio je 0,9191 za QSAR-NN1, 0,9338 za QSAR-NN2 i 0,9709 za QSAR-NN3). Usporedba neuronskih mreža i višestrukih linearnih regresija zasnovanih na kvantitativnom odnosu struktura-aktivnost “QSAR-MLR” otkrila je superiornost modela QSAR-NN (korijenske srednje kvadratne pogreške za ukupni skup podataka za modele QSAR-NN bile su 10,6517 % za QSAR-NN1, 9,1991 % za QSAR-NN2, i 5,8869 % za QSAR-NN3, a za modele QSAR-MLR 20,1865 % za QSAR-MLR1, 19,3815 % za QSAR-MLR2, i 16,2062 % za QSAR-MLR3).

A simple method for finding optimal paths of hot and cold streams inside shell and tube heat exchangers to reduce pumping cost in heat exchanger network problems [Elektronička građa] / V. Sadri, Hadi Soltani, S. Rahimzadeh. - Graf. prikazi.
Bibliografija: 43 jed. - Summary. - In this paper, a simple method is presented for the synthesis and retrofit of heat exchanger networks (HENs) by considering pressure drop as well as finding proper path of streams inside heat exchangers (HEs) to reduce the pumping cost of network. Generally, HEN problems lead to MINLP models which have convergence difficulties due to the existence of both continuous and integer variables. In this study, instead of solving these variables simultaneously, a combination of Genetic Algorithm (GA) with Quasi Linear Programming (QLP) and Integer Linear Programming (ILP) was used for solving the problem. GA was used to find optimal HENs structure and streams paths, whereas continuous variables were solved by QLP. For the retrofit of HENs, a modified ILP model was used. Results show that the proposed method has the ability to reduce the cost of annual pumping due to considering optimal paths for streams in the HEs compared to the literature.

Adsorption of reactive dyes from aqueous solution using activated carbon prepared from plantain leaf sheath waste [Elektronička građa] / G. Sangavi, Argho Bakshi, Mathangi Ganapathy, Nandhini Devi Ganesan. - Ilustr., graf. prikazi.
Bibliografija: 45 jed. - Summary. - All parts of the plantain are widely used in India for various purposes. But plantain leaf sheath always ends up as waste material which accumulates as a biowaste. The present study focuses on the preparation of activated carbon using phosphoric acid as activating agent, and its efficacy as an adsorbent for the removal of reactive dyes, Reactive Green 19, and Reactive Red 141. Batch adsorption studies have been conducted and optimum adsorption conditions were determined as a function of contact time, initial dye concentration, adsorbent dosage, and pH. The experimental data were analyzed using Langmuir, Freundlich and Temkin isotherm models. The pseudo-first and second-order, intraparticle diffusion, and Elovich models were used to analyze the kinetic parameters of the adsorption system. Under the optimum conditions (initial dye concentration = 200 mg L–1, adsorbent dose = 1 g, pH = 2, contact time = 220 min for reactive green 19 and 180 min for reactive red 141), maximum percentage removal for reactive green 19 and reactive red 141 were obtained as 65.9 % and 72.7 %, respectively. The results demonstrate that activated carbon produced from chemical activation of the plantain waste has the potential of adsorbing reactive dyes from industrial effluents.

Analysis of electrocoagulation process efficiency of compost leachate with the first order kinetic model [Elektronička građa] / Marjana Simonič, Mirjana Čurlin, Lidija Fras Zemljič. - Ilustr., graf. prikazi.
Bibliografija: 10 jed. - Summary. - Large quantities of leachate are generated from the water release during the decomposition of the biodegradable waste. The composition of compost leachate is very complex and its treatment is necessary before releasing into the environment. The possibilities of treating compost leachate by electrocoagulation have been extensively studied. The scope of this work was to investigate applicability of the first order kinetic model for degradation of metal and organic compounds from compost leachate by electrocoagulation process. Experimental results showed 75 % removal efficiency of Cu2+ and 65 % of Zn2+, while chemical oxygen demand was reduced by 36 %. According to obtained kinetic parameters, simulation of metal removal efficiency was performed in batch reactor. This way optimal electrocoagulation time which is needed for 95 % efficiency of metal removal was determined at 120th min for Zn2+ and 102nd min for Cu2+.

Antibakterijska svojstva punila mikro TiO2 u biokompozitima na osnovi polietilena niske gustoće i rižinih ljuskica [Elektronička građa] / Antonija Kovačević, Dajana Kučić Grgić, Emi Govorčin Bajsić, Nikolina Mrkonjić. - Ilustr., graf. prikazi.
Bibliografija: 21 jed. - Sažetak ; Summary. - Polietilen niske gustoće (LDPE) sintetski je nerazgradljiv polimer koji se najčešće upotrebljava kao ambalažni materijal za pakiranje hrane, međutim njegova nerazgradljivost ima loš utjecaj na okoliš. Razvoj i uporaba biorazgradljivih polimernih materijala ili plastike kao ambalažnog materijala za pakiranje hrane danas je u značajnom porastu. Biopolimeri predstavljaju jednu od najznačajnijih alternativa za razvoj ekološki prihvatljive ambalaže u prehrambenoj industriji zbog njihove biorazgradljivosti. Cilj ovoga rada bio je pripremiti biokompozite na osnovi linearnog polietilena niske gustoće (LDPE), rižinih ljuskica (RLJ) i punila mikro titanijeva dioksida (mTiO2) kako bi se dobili biorazgradljivi biokompoziti s antibakterijskim učinkom, pogodni za primjenu kao ambalažni materijali u prehrambenoj industriji. Biokompoziti su pripremljeni umješavanjem u laboratorijskoj Brabender gnjetilici. Ispitan je utjecaj različitog masenog udjela mTiO2 (w = 0,5, 1,0, 1,5 i 2,0 %) na inhibiciju bakterijske kulture Escherichia coli, Pseudomonas aeruginosa i Bacillus subtilis. Rezultati pokazuju da je mTiO2 inhibirao rast bakterijske kulture Escherichia coli, Pseudomonas aeruginosa i Bacillus subtilis kod masenog udjela mTiO2 od 1,5 i 2,0 % (broj stanica bakterijskih kultura se smanjivao). Rezultati TGA i DSC mjerenja pokazuju prisutnost mTiO2 u biokompozitima. - Low-density polyethylene (LDPE) is a synthetic, non-degradable polymer most commonly used as a food packaging material; however, its non-degradability has an adverse effect on the environment. The development and use of biodegradable polymeric materials or plastics as packaging materials for food packaging has significantly increased. Biopolymers present one of the best alternatives for development of environmentally friendly packaging materials in the food industry due to their biodegradability. The aim of this study was to prepare biocomposites of low-density polyethylene (LDPE), rice husk (RH) and micro titanium dioxide (mTiO2) as a filler in order to obtain a biodegradable and antibacterial material suitable for use as a packaging material in the food industry. The biocomposites were prepared by melt mixing in laboratory Brabender mixer. Antibacterial effect of different mass fraction of mTiO2 (w = 0.5; 1.0; 1.5, and 2.0 %) on bacterial cultures of Escherichia coli, Pseudomonas aeruginosa, and Bacillus subtilis was investigated. The results showed that mTiO2 inhibited the growth of bacterial cultures of Escherichia coli, Pseudomonas aeruginosa, and Bacillus subtilis at the mTiO2 mass fraction of 1.5 and 2.0 % (the number of bacterial culture cells decreased). The results of TGA and DSC measurements showed that TiO2 was blended successfully into the biocomposites.

Artificial neural network and support vector regression applied in quantitative structure-property relationship modelling of solubility of solid solutes in supercritical CO2 [Elektronička građa] / Mohammed Moussaoui, Maamar Laidi, Salah Hanini, Mohamed Hentabli. - Graf. prikazi.
Bibliografija: 134 jed. - Summary ; Sažetak. - In this study, the solubility of 145 solid solutes in supercritical CO2 (scCO2) was correlated using computational intelligence techniques based on Quantitative Structure-Property Relationship (QSPR) models. A database of 3637 solubility values has been collected from previously published papers. Dragon software was used to calculate molecular descriptors of 145 solid systems. The genetic algorithm (GA) was implemented to optimise the subset of the significantly contributed descriptors. The overall average absolute relative deviation MAARD of about 1.345 % between experimental and calculated values by support vector regress SVR-QSPR model was obtained to predict the solubility of 145 solid solutes in supercritical CO2, which is better than that obtained using ANN-QSPR model of 2.772 %. The results show that the developed SVR-QSPR model is more accurate and can be used as an alternative powerful modelling tool for QSAR studies of the solubility of solid solutes in supercritical carbon dioxide (scCO2). The accuracy of the proposed model was evaluated using statistical analysis by comparing the results with other models reported in the literature. - U ovom je istraživanju korelirana topljivost 145 čvrstih otopljenih tvari u superkritičnom CO2 (scCO2) primjenom tehnika računalne inteligencije zasnovanim na modelima kvantitativne strukture i svojstva (QSPR). Baza podataka 3637 topljivosti prikupljena je iz prethodno objavljenih radova. Program Dragon primijenjen je za izračunavanje molekularnih deskriptora 145 čvrstih sustava. Genetski algoritam (GA) implementiran je kako bi se optimizirao podskup deskriptora sa značajnim doprinosom. Ukupno prosječno apsolutno relativno odstupanje MAARD od oko 1,345 % između eksperimentalnih i izračunatih vrijednosti pomoću regresije potpornih vektora modelom SVR-QSPR dobiveno je za predviđanje topljivosti 145 čvrstih otopljenih tvari u superkritičnom CO2, što je bolje od onog dobivenog primjenom modela ANN-QSPR (2,772 %). Rezultati pokazuju da je razvijeni model SVR-QSPR precizniji i da se može primijeniti kao alternativni alat za modeliranje QSAR studija topljivosti otopljenih čvrstih tvari u superkritičnom ugljikovu dioksidu (scCO2). Točnost predloženog modela procijenjena je statističkom analizom uspoređivanjem rezultata s ostalim modelima zabilježenim u literaturi.

Competitive heavy metal removal from binary solution [Elektronička građa] / Anita Bašić, Mario Nikola Mužek, Lea Kukoč-Modun, Sandra Svilović. - Graf. prikazi.
Bibliografija: 18 jed. - Summary ; Sažetak. - The removal of copper and cobalt ions from binary metal solutions on zeolite NaX by ion exchange process was investigated. Experiments were conducted in unbaffled glass reactor with a Rushton turbine as a stirrer. The dependence of ion exchange kinetics and the amount exchanged were tested using different initial concentrations of metal ions in mixtures. The results obtained indicate that the removal efficiency depends on the initial heavy metal concentrations in binary solutions. Experimental kinetics data were analysed using Ritchie and Weber-Morris models. According to AARD values, the rate in this study was reaction-controlled. - Ispitano je uklanjanje iona bakra i kobalta iz binarnih otopina metala ionskom izmjenom na zeolitu NaX. Eksperimenti su provedeni u staklenom kotlastom reaktoru bez razbijala virova. Kao miješalo upotrijebljena je Rushtonova turbina. Ovisnost kinetike izmjene iona i izmijenjene količine iona metala ispitana je pri različitim početnim koncentracijama iona metala u smjesama. Prema dobivenim rezultatima, učinkovitost uklanjanja iona metala iz otopina ovisi o početnim koncentracijama metala u binarnim otopinama. Kinetički podatci dobiveni eksperimentom analizirani su Ritchievim i Weber-Morrisovim modelom. Prema vrijednostima AARD-a, ukupna brzina procesa u ovoj studiji kontrolirana je reakcijom.

Effect of silicate, carbonate, calcium lignosulphonate, and silicic acid additives on ammonium nitrate degradation [Elektronička građa] / Ahmet Ozan Gezerman. - Ilustr., graf. prikazi.
Bibliografija: 32 jed. - Summary ; Sažetak. - Ammonium nitrate is the most commonly used nitrogen fertilizer in the agriculture and plays an important role in the development of leaves and stems in plants. The storage and production of ammonium nitrate at the industrial scale can result in degradation and caking. Various solutions have been proposed, however, to date, an effective solution to the degradation problem has not been identified. The addition of silicic acid during the production of ammonium nitrate prevents the double salt formation caused by sulphuric acid additive, which is a process requirement. Silicic acid was combined with calcium carbonate in the dilution stage in order to increase the fracture strength of ammonium nitrate. With the addition of calcium lignosulphonate, the phase conversion of ammonium nitrate granules was completed more rapidly, and thus the problem of degradation was prevented. Thus, chemical and physical degradation of the ammonium nitrate structure were prevented during the 2-year storage period, which was adopted as the standard for the ammonium nitrate production process. - Amonijev nitrat najčešće je dušično gnojivo u poljoprivredi i ima važnu ulogu u razvoju lišća i stabljika. Skladištenje i proizvodnja amonijeva nitrata u industrijskim razmjerima može rezultirati razgradnjom i stvrdnjavanjem. Predložena su razna rješenja, međutim do danas nije pronađeno učinkovito rješenje problema razgradnje. Dodavanje silicijeve kiseline tijekom proizvodnje amonijeva nitrata sprječava stvaranje dvostruke soli uzrokovano dodatkom sumporne kiseline, što je preduvjet postupka. Silicijska kiselina kombinirana je s kalcijevim karbonatom u fazi razrjeđivanja kako bi se povećala čvrstoća amonijeva nitrata. Dodavanjem kalcijeva lignosulfonata brže je dovršena fazna pretvorba granula amonijeva nitrata, čime je spriječen problem razgradnje. Dakle, spriječeno je kemijsko i fizičko propadanje strukture amonijeva nitrata tijekom dvogodišnjeg skladištenja, što je prihvaćeno kao standard za postupak proizvodnje amonijeva nitrata.

An efficient biosurfactant by Pseudomonas stutzeri Z12 isolated from an extreme environment for remediation of soil contaminated with hydrocarbons [Elektronička građa] / Sudabeh Pourfadakari, Sahand Jorfi, Shokooh Ghafari. - Ilustr., graf. prikazi.
Bibliografija: 59 jed. - Summary. - Capability of a biosurfactant produced by Pseudomonas stutzeri Z12 for the removal of hydrocarbons from oily sludge contaminated soil was investigated. The effect of operating parameters, including pH, critical micelle concentration (CMC), salinity, and contact time were studied. The chemical structure of produced biosurfactant was characterized using FTIR and LC-MS-MS analysis, which revealed that the extracted biosurfactant was a combination of both mono- and di-rhamnolipid congeners. The main three congeners RhaC12:1C10 (529.9 m z–1), RhaC12C10 (531 m z–1), and RhaC10C10 (503.2 m z–1) were associated to mono-rhamnolipid, while five congeners, RhaRhaC10C8 (621.2 m z–1), RhaRhaC12C12 (707.7), RhaRhaC10C12 (677.1), RhaRhaC10C12:1 (675.3 m z–1), and RhaRhaC10C1 (649.5 m z–1) were associated to di-rhamnolipid structures. The critical micelle concentration (CMC) was 80 mg L–1, and emulsification index (E24) values for n-hexadecane, n-hexane, kerosene, diesel oil, xylene, and crude oil were 62.1, 57.6, 54.4, 41.5, 46.9, and 30.2 %, respectively.

Fish canning wastewater treatment in sequencing batch reactor with activated sludge [Elektronička građa] / Dijana Grgas, Marina Ugrina, Merima Toromanović, Jasmina Ibrahimpašić, Tea Štefanac, Tibela Landeka Dragičević. - Graf. prikazi.
Bibliografija: 19 jed. - Summary. - The biological performance of flocculent sludge in sequencing batch reactor for the treatment of fish canning wastewater was evaluated in terms of organic matter and nutrient removal by gradual increase of salt concentration in the nitritation-denitritation process. Salinity negatively affected the biological system performance in a way that reduced organic and nutrient removal. The removal efficiency of organic matter and nitrogen showed good performance below 20 g NaCl/L, while phosphate accumulating organisms activity was deteriorated and declined during whole experiment. Nitrogen removal occurred as ammonium oxidation with nitrite accumulation. Nitrite reduction was not affected by salt concentration.

From bio-waste to bone substitute [Elektronička građa] : synthesis of biomimetic hydroxyapatite and its use in chitosan-based composite scaffold preparation / Antonia Ressler, Ana Gudelj, Karla Zadro, Maja Antunović, Matija Cvetnić, Marica Ivanković, Hrvoje Ivanković. - Ilustr., graf. prikazi.
Bibliografija: 53 jed. - Summary. - Nanocomposite structure of the bone can be mimicked by chitosan/hydroxyapatite (CS/HAp) composite scaffold. Biological hydroxyapatite (HAp) contains various ions, which have a crucial role in bone growth. The aim of the present work was to synthesize biomimetic hydroxyapatite and prepare composite scaffolds based on chitosan, where HAp was synthesised from hen eggshells, seashells and cuttlefish bone. The powders were composed of nano-structured calcium deficient HAp and amorphous calcium phosphate (ACP). In the as-prepared powders, Sr2+, Mg2+ and Na+ ions were detected as a result of using biogenic precursor of Ca2+ ions. Highly porous CS/HAp structures have been prepared by freeze-gelation technique. The CS/HAp scaffolds have shown highly porous structure with very well interconnected pores and homogeneously dispersed HAp particles. The MTT assay of CS/HAp scaffolds has shown no toxicity, and the live/dead assay has confirmed good viability and proliferation of seeded cells.

Intergranular corrosion of Cu-Al-Ni alloy in 0.5 mol dm−3 H2SO4 solution [Elektronička građa] / Ladislav Vrsalović, Senka Gudić, Lana Terzić, Ivana Ivanić, Stjepan Kožuh, Mirko Gojić, Emeka Emmanuel Oguzie. - Ilustr. ; graf. prikazi.
Bibliografija: 31 jed. - Abstract ; Sažetak. - The corrosion behaviour of Cu-Al-Ni alloy in 0.5 mol dm–3 H2SO4 solution was investigated by electrochemical methods including open circuit potential measurement, electrochemical impedance spectroscopy measurements, linear and potentiodynamic polarization. Measurements were performed in 0.5 mol dm–3 H2SO4 at temperatures 20 and 40 °C. After polarization testing, corroded electrode surfaces were ultrasonically cleaned in deionized water and examined by light and scanning electron microscopy, while the elemental composition at individual points of the alloy surface was determined by EDS analysis. The results of the investigations revealed the occurrence of intergranular corrosion on the Cu-Al-Ni surface, which became more pronounced with increasing temperature. - Korozijsko ponašanje Cu-Al-Ni legure u 0,5 mol dm–3 H2SO4 otopini ispitivano je elektrokemijskim metodama kao što su mjerenje potencijala otvorenog strujnog kruga, mjerenje metodom elektrokemijske impedancijske spektroskopije, linearne i potenciodinamičke polarizacije. Mjerenja su provedena u 0,5 mol dm–3 H2SO4 pri temperaturama od 20 i 40 °C. Nakon polarizacijskih mjerenja korodirane površine elektroda ultrazvučno su očišćene u deioniziranoj vodi i ispitane svjetlosnim i pretražnim elektronskim mikroskopom, dok je elementarni sastav na pojedinim točkama na površini određen EDS analizom. Rezultati ispitivanja pokazali su da dolazi do interkristalne korozije na površini Cu-Al-Ni legure, čiji intenzitet raste s povećanjem temperature elektrolita.

Karakterizacija mikroplastike u sedimentu plaže Prapratno [Elektronička građa] / Matko Erceg, Pero Tutman, Dubravka Bojanić Varezić, Anđela Bobanović. - Ilustr., graf. prikazi.
7. hrvatski simpozij o kemiji i tehnologiji makromolekula, Zagreb, 27.9.2019. - Bibliografija: 11 jed. - Sažetak ; Summary. - Mikroplastika predstavlja ozbiljan problem u morskom i priobalnom okolišu. Analiziran je uzorak mikroplastike iz sedimenta plaže Prapratno na poluotoku Pelješcu, Hrvatska. Uzorkovanje i laboratorijsko odvajanje provedeni su prema DeFishGear protokolu. Svaki ispitak svrstan je u određenu kategoriju te je svakom određena masa, boja, prozirnost, maksimalna dimenzija i površina. Identifikacija je provedena infracrvenom spektroskopijom (FTIR) – HATR tehnikom. Otpad s plaže Prapratno sastoji se uglavnom od polietilena te, u manjem udjelu, od polistirena i polipropilena. - Microplastics represent a major problem in the marine and coastal environment. In this work, microplastics from the sediment of Prapratno beach on the Pelješac Peninsula (Croatia) were analysed. Sampling and laboratory separation were performed according to the DeFishGear protocol (Derelict Fishing Gear Management System in the Adriatic Region). The microplastic waste from Prapratno beach sediment consisted of 116 specimens, which could be classified into 6 micro litter categories according to EU TG ML Master List (Fig. 1). Fragments were found to be the predominant category of microplastic waste from the sediment of Prapratno beach, followed by granules, films, pellets and foams, which were present in approximately the same number, while filaments were the least represented category (Fig. 2). The most important categories by mass were granules and fragments, followed by pellets, while films, foams and filaments made up a very small content of the total sample mass (Fig. 3). The numerical contents (Fig. 4), did not correspond to the mass contents (Fig. 3) of individual categories due to the different densities and thicknesses of the specimens in each category. Almost all the base colours were present in the analysed samples (Fig. 5), while 90.52 % of specimens were opaque (Fig. 6). The maximum dimension and surface area of each specimen was determined by Digimizer Image Analysis Software. Maximum dimensions in the range of 1–5 mm were observed in 52.59 % of the specimens, thus belonging to large microplastics (LMP), while 47.41 % of the specimens had maximum dimensions in the range of 5–20 mm, thus belonging to so-called mezzo litter. The distribution of specimen dimensions within LMP is shown in Fig. 8, and within mezzo litter in Fig. 9. The fraction of each category in the total sample surface area is shown in Fig. 10.

Lattice Boltzmann modeling-based design of a membrane-free liquid-liquid microseparator [Elektronička građa] / Filip Strniša, Polona Žnidaršič-Plazl, Igor Plazl. - Ilustr., graf. prikazi.
Bibliografija: 21 jed. - Summary. - The benefits of continuous processing and the challenges related to the integration with efficient downstream units for end-to-end manufacturing have spurred the development of efficient miniaturized continuously-operated separators. Membrane-free microseparators with specifically positioned internal structures subjecting fluids to a capillary pressure gradient have been previously shown to enable efficient gas-liquid separation. Here we present initial studies on the model-based design of a liquid-liquid microseparator with pillars of various diameters between two plates. For the optimization of in silico separator performance, mesoscopic lattice-Boltzmann modeling was used. Simulation results at various conditions revealed the possibility to improve the separation of two liquids by changing the geometrical characteristics of the microseparator.

Neidealno strujanje u modelnim cijevima [Elektronička građa] / Filip Kurt, Katarina Licht, Vanja Kosar. - Ilustr., graf. prikazi.
Bibliografija: 8 jed. - Sažetak ; Summary. - Cilj ovog rada bio je istražiti strujanje kapljevine u trima različitim modelnim cijevima: ravnoj praznoj cijevi, cijevi ispunjenoj staklenim kuglicama i praznoj spiralnoj cijevi. Pri tome je osnovni koncept sadržan u pojmu raspodjele vremena zadržavanja kapljevine (RVZ). Kako bi se dobile RVZ krivulje, eksperimentalno je mjerena koncentracija inertne tvari (engl. tracer) na izlasku iz cijevi tijekom vremena. Kao inertna tvar upotrijebljena je otopina vodljive soli KCl. Pomoću modela aksijalne disperzije izračunate su vrijednosti srednjeg vremena zadržavanja i disperzijskog broja za različite protoke (100 – 600 ml min–1) i volumene inertne tvari (0,3 i 1 ml) te je dan kvantitativan opis odstupanja od idealnog strujanja. - The aim of this paper was to investigate the flow of liquid in three different model tubes: an empty straight tube, a tube filled with glass beads, and an empty spiral tube. In doing so, the basic concept is contained in the notion of residence time distribution (RTD). In order to obtain RTD curves, the tracer concentration at the exit of the tube was experimentally measured over time. The KCl conductive salt solution was used as the tracer. Using the axial dispersion model, the mean retention time and dispersion number values were calculated for different flows (100–600 ml min–1) and volumes of tracer (0.3 and 1 ml), and a quantitative description of deviations from the ideal plug flow was given.

Priprava celuloznih hidrogelova modificiranih 2-dimetilaminoetil-metakrilatom i srebrovim nanočesticama [Elektronička građa] / Roko Blažic, Katarina Lenac, Elvira Vidović. - Ilustr., graf. prikazi.
7. hrvatski simpozij o kemiji i tehnologiji makromolekula, Zagreb, 27.9.2019. - Bibliografija: 22 jed. - Sažetak ; Summary. - Hidrogelovi su materijali koji se odlikuju mogućnošću upijanja velike količine vode. Celuloza je vrlo rasprostranjen biokompatibilan i biorazgradljiv polisaharid s hidrofilnim OH skupinama u strukturi koje omogućuju raznovrsne modifikacije. Uvođenjem novih funkcijskih skupina na osnovni polisaharidni lanac moguće je mijenjati svojstva hidrogela kako bi se pripremili hidrogelovi željenih svojstava: antibakterijska svojstva, osjetljivost na vanjske podražaje i slično. U ovom radu provedeno je graftiranje dimetilaminoetil-metakrilata (DMAEMA) na celulozu. Polimerizacija DMAEMA na celulozu provedena je u otapalu N,N-dimetil acetamid/LiCl uz peroksidni inicijator pri temperaturi od 90 °C te N,N-metilen-bis-akrilamid (MBA) kao umreživačem. U pripravljene hidrogelove unesene su i nanočestice srebra, dobro poznate po antibakterijskim svojstvima. Relativni udio PDMAEMA u hidrogelovima određen je pomoću infracrvene spektroskopije. Morfologija osušenih uzorka i prisutnost srebra određene su pretražnom elektronskom mikroskopijom koja je pokazala da je dodatkom PDMAEMA i sušenjem hidrogelova ekstrakcijom zamrzavanjem dobivena vrlo porozna struktura. Na taj način pospješeno je i vezanje nanočestica srebra na hidrogelove. Uzorci kopolimera priređeni sušenjem u sušioniku pokazuju veći stupanj bubrenja u deioniziranoj vodi (~ 109 %) u odnosu na čistu celulozu (80 %). Isti materijali sušeni ekstrakcijom zamrzavanjem i tako oblikovani u porozne hidrogelove pokazuju znatno veće vrijednosti stupnja bubrenja (256 % i 505 %) naspram čiste celuloze (80 %). - Hydrogels are materials displaying the ability to absorb large amounts of water. Cellulose is a widespread, biocompatible, and biodegradable polysaccharide with hydrophilic OH groups in a structure that allows various modifications. By introducing new functional groups to the repeating units of the polysaccharide chain, it is possible to modify properties of the material in order to prepare hydrogels of desired properties such as antibacterial properties or response to external stimuli. In this work, 2-dimethylaminoethyl methacrylate (DMAEMA) grafting on cellulose was performed. The polymerization of DMAEMA on cellulose was carried out in solvent N,N-dimethyl acetamide / LiCl with a peroxide initiator at 90 °C and N,N-methylene-bis-acrylamide (MBA) as a crosslinker. Nanoparticles of silver, well known for their antibacterial properties, were also introduced into the prepared hydrogels. The relative proportion of PDMAEMA in hydrogels was determined by infrared spectroscopy. The morphology of the dried samples and the presence of silver were determined by scanning electron microscopy, which showed that the addition of PDMAEMA and drying of the hydrogels by freeze-extraction resulted with a very porous structure. In this way, the binding of silver nanoparticles to hydrogels was also facilitated. Samples of copolymers prepared by drying in a dryer showed a higher degree of swelling in water (~ 109 %) than pure cellulose (80 %). The same materials prepared by freeze-drying formed into porous hydrogels showed much higher swelling rates (256 % and 505 %) compared to pure cellulose (80 %).

Priprava i karakterizacija biokompozita na osnovi polilaktida (PLA) i bakterijske nanoceluloze (BNC) [Elektronička građa] / Nikolina Mrkonjić, Gordana Martinko, Emi Govorčin Bajsić, Igor Slivac, Vedrana Špada, Tamara Holjevac Grgurić. - Ilustr., graf. prikazi.
7. hrvatski simpozij o kemiji i tehnologiji makromolekula, Zagreb, 27.9.2019. - Bibliografija: 24 jed. - Sažetak ; Summary. - Polilaktidna kiselina (PLA) i bakterijska nanoceluloza (BNC) zbog svoje biorazgradljivosti, biokompatibilnosti i netoksičnosti imaju velik potencijal za primjenu u biomedicini. Cilj ovog rada bio je pripraviti i ispitati biokompozit PLA/BNC. Istražen je utjecaj BNC-a na morfološku strukturu, kemijski sastav, toplinska svojstva, toplinsku postojanost i hidrofobnost PLA te zasijavanje i rast stanica biokompozita PLA/BNC primjenom pretražnog elektronskog mikroskopa (SEM), infracrvene spektroskopije (FTIR), diferencijalne pretražne kalorimetrije (DSC) i termogravimetrijske analize (TGA) te određivanjem kontaktnog kuta i metodom MTT. Dodatkom BNC-a u PLA dolazi do pomaka staklišta (Tg) prema nižim temperaturama, što ukazuje na veću pokretljivost amorfne faze PLA te porasta stupnja kristalnosti zbog nukleacijskog učinka celuloze. Početak toplinske razgradnje pomaknut je na niže temperature u odnosu na čisti PLA, što ukazuje na smanjenje toplinske postojanosti PLA dodatkom BNC-a. Biokompozit PLA/BNC pokazuje poroznu, vlaknastu strukturu. Test zasijavanja stanica pokazao je da je biokompozit PLA/BNC pogodan za prihvaćanje i rast humanih stanica, pa je prema tome potencijalno primjenjiv u regenerativnoj medicini i tkivnom inženjerstvu. - Polylactic acid (PLA) and bacterial nanocellulose (BNC) are promising materials in medicine due to their biodegradability, biocompatibility, and non-toxicity. The aim of this work was to prepare and characterize the PLA/BNC biocomposite. Morphology, chemical composition, thermal properties, thermal stability, hydrophobicity and cell seeding, and growth of the PLA/BNC biocomposite were characterized by means of scanning electron microscopy (SEM), Fourier transform infrared spectra (FTIR), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), contact angle, and MTT method. DSC showed that the glass transition temperature (Tg) of PLA decreased with the addition of BNC due to higher mobility of amorphous PLA phase. The degree of crystallinity increased due to nucleation effect of cellulose. With the addition of BNC, the thermal stability of biocomposite decreased. The PLA/BNC biocomposite exhibited a porous, fibrous structure. The cell seeding test showed the PLA/BNC biocomposite to be suitable for growth of human cells, and therefore, potentially applicable in regenerative medicine and tissue engineering.

QSPR studies of carbonyl, hydroxyl, polyene indices, and viscosity average molecular weight of polymers under photostabilization using ANN and MLR approaches [Elektronička građa] / Hadjira Maouz, Latifa Khaouane, Salah Hanini, Yamina Ammi, Mabrouk Hamadache, Maamar Laidi. - Graf. prikazi.
Bibliografija: 56 jed. - Summary ; Sažetak. - One of the main disadvantages of the use of synthetic or semi-synthetic polymeric materials is their degradation and aging. The purpose of this study was to use artificial neural networks (ANN) and multiple linear regressions (MLR) to predict the carbonyl, hydroxyl, and polyene indices (ICO, IOH, and IOP), and viscosity average molecular weight (MV) of poly(vinyl chloride), polystyrene, and poly(methyl methacrylate). These physicochemical properties are considered fundamental during the study of photostabilization of polymers. From the five repeating units of monomers, the structure of the polymer studied is shown. Quantitative structure-property relationship (QSPR) models obtained by using relevant descriptors showed good predictability. Internal validation {R2, RMSE, and Q2LOO}, external validation {R2, RMSE, Q2pred, rm2, Δrm2, k, and k’}, and applicability domain were used to validate these models. The comparison of the results shows that the ANN models are more efficient than those of the MLR models. Accordingly, the QSPR model developed in this study provides excellent predictions, and can be used to predict ICO, IOH, IOP, and MV of polymers, particularly for those that have not been tested. - Jedan od glavnih nedostataka upotrebe sintetičkih ili polusintetičkih polimernih materijala je njihova razgradnja i starenje. Svrha ove studije je primjena umjetnih neuronskih mreža (ANN) i višestrukih linearnih regresija (MLR) za predviđanje karbonilnih, hidroksilnih i polienskih indeksa (ICO, IOH i IOP) i prosječne molekulske mase viskoznosti (MV) poli(vinil-klorida), polistirena i poli(metil metakrilata). Ta fizikalno-kemijska svojstva smatraju se važnim tijekom proučavanja fotostabilizacije polimera. Iz pet ponavljajućih jedinica monomera prikazana je struktura ispitivanog polimera. Kvantitativni modeli odnosa strukture-svojstava (QSPR) dobiveni primjenom relevantnih deskriptora pokazali su dobru predvidljivost. Za potvrdu tih modela provedene su: interna provjera {R2, RMSE i Q2LOO}, vanjska provjera {R2, RMSE, Q2pred, rm2, Δrm2, k i k’} i domena primjenjivosti. Usporedba rezultata pokazuje da su modeli ANN učinkovitiji od modela MLR. Prema tome, model QSPR razvijen u ovoj studiji pruža izvrsna predviđanja i može se primjenjivati za predviđanje ICO, IOH, IOP i MV polimera, posebno za one koji nisu testirani.

Removal efficiency of lipid-regulating drug clofibric acid from the aquatic environment by calcined anionic clay ZnAl-CO3 [Elektronička građa] / El Hassane Mourid, Mohamed Lakraimi, Lhaj Benaziz, Mustapha Cherkaoui. - Ilustr., graf. prikazi.
Bibliografija: 70 jed. - Summary. - Clofibric acid (CA) is widely used as regulator of lipid levels in blood; it is considered one of the residual drugs that have a high persistence in the aquatic environment. After wastewater treatment, only a small amount of CA can be removed. The aim of this work was to investigate the reduction of CA in contaminated wastewater using calcined anionic clay ZnAl-CO3, which was chosen for its higher adsorption capacity, recyclability, and non-regeneration of sludge. The maximum retention amount, Qm, exceeded 2220 mg g–1, and the value of DH° suggested a physical process. The removal rate achieved 90 %, and the remaining quantity was widely below the tolerance thresholds. Retention was achieved by hydrogen bonds and electrostatic interactions between the adsorbate molecules. Recycling tests clearly suggested that this material is recyclable, promising, and very effective compared to other adsorbents. This retention contributes to the attenuation of persistent lipid regulator.

Bibliografija: 163 jed. - Summary. - Leachate waste consists of various mixtures of organic, inorganic, and heavy metal contaminants, which are responsible for groundwater and surface water contamination. Landfills apply physical, chemical, and biological processes for the treatment of leachate. Most studies on leachate treatment by coagulation and flocculation are based on the selection and performance of natural based biopolymers in comparison with various inorganic metal salts and grafted polymers used for the removal of contaminants. In addition, adsorption processes utilizing non-conventional activated carbons as absorbents are the current emerging focus of the researchers in leachate treatment. These adsorbents are low-in-cost, efficient, and renewable compared to conventional adsorbents. The present paper aimed to evaluate and review the technology utilising various greener approaches in coagulation, flocculation, and adsorption as the physicochemical approaches to leachate treatment. The challenges and future work regarding the development of these green products in the commercial markets were comprehensively evaluated.

Uklanjanje bojila iz tekstilne otpadne vode ultrafiltracijskim membranama [Elektronička građa] / Iva Ćurić, Davor Dolar, Klara Karadakić. - Ilustr., graf. prikazi.
Bibliografija: 44 jed. - Sažetak ; Summary. - Otpadne vode tekstilne industrije pripadaju kategoriji najjače onečišćenih industrijskih otpadnih voda te su posebna opasnost za vodeni okoliš. Cilj ovog istraživanja bio je ispitati membransku učinkovitost zadržavanja bojila iz tekstilne otpadne vode (TOV) s komercijalnim ultrafiltracijskim (UF) membranama (GH, GK, PT, PU, PW, MW) širokog područja graničnih molekulskih masa (MWCO), od 2 do 50 kDa. Testirane UF membrane rezultirale su smanjenjem obojenja i intenziteta obojenja od 56,35 % do 97,93 %. Membrane nižih MWCO vrijednosti (ispod 3 kDa) mogu se smatrati prikladnim za uklanjanje bojila iz realnog uzorka TOV-a. - Wastewater from the textile industry belongs to the category of the most polluted industrial wastewaters and poses a special danger to the aquatic environment. The aim of this study was to examine the membrane retention efficiency of textile wastewater (TOV) with commercial ultrafiltration (UF) membranes (GH, GK, PT, PU, PW, MW) with a wide range of molecular weight cut-off (MWCO), 2–50 kDa. The tested UF membranes resulted in a reduction in colour and colour intensity from 56.35 % to 97.93 %. Membrane of lower MWCO values (below 3 kDa) may be suitable for removing dyes from the real TOV sample.

Utjecaj istraživača na rezultate kinetičke analize toplinske razgradnje polimera [Elektronička građa] / Matko Erceg, Miće Jakić, Irena Krešić. - Graf. prikazi.
Bibliografija: 17 jed. - Sažetak ; Summary. - U ovom radu ispitivan je utjecaj istraživača na rezultate kinetičke analize neizotermne toplinske razgradnje četiri polimera. Analizirani polimeri imaju različite stupnjeve složenosti razgradnog procesa. Kinetičku analizu provelo je troje istraživača, jedan znanstveni savjetnik, jedan znanstveni suradnik te jedan doktorand, a svi su se koristili istim eksperimentalnim termogravimetrijskim podatcima te istim kinetičkim programom (Netzsch Thermokinetics Professional). Rezultati nedvojbeno pokazuju da istraživači imaju značajan utjecaj na rezultate kinetičke analize, budući da su procese neizotermne toplinske razgradnje svih uzoraka opisali različitim kinetičkim shemama i time različitim kinetičkim parametrima. - In this paper, the influence of researchers on the results of kinetic analysis of non-isothermal thermal decomposition of four polymers was investigated. Four polymers having different degrees of complexity of the degradation process were analysed. The kinetic analysis was performed by three researchers: one scientific advisor with tenure, one research associate and one doctoral student, all of whom used the same experimental thermogravimetric data. Kinetic analysis was performed using the Netzsch Thermokinetics Professional program. The results unequivocally showed that the researchers have a significant influence on the results of kinetic analysis, since they described the processes of the non-isothermal thermal decomposition of all samples by different kinetic schemes, and thus by different kinetic parameters.

Valorization of banana peel for citric acid production under solid state fermentation with Aspergillus niger [Elektronička građa] / Teerin Chysirichote. - Graf. prikazi.
Bibliografija: 58 jed. - Summary. - Valorization of banana peel (BP) through solid state fermentation (SSF) was aimed in this research. The appropriate conditions of citric acid (CA) production by SSF of Aspergillus niger were investigated. Firstly, the optimum initial pH of the BP and the aeration rate were studied by conducting SSF in a 250-mL flask and 2-L glass column, respectively. It was found that the initial pH of the BP and aeration rates affected the CA production. The results showed that the initial pH of 5.0 and 1.0 vvm aeration were appropriate for the CA production of A. niger using BP as a substrate. The problem of rising temperature during SSF was found when applying the optimum condition to the SSF in the 20-L packed bed bioreactor (PBB), which caused a decrease in the CA production compared to that of the glass column. The cooling air jacket constructed to the PBB to remove the heat during the SSF helped increase the CA production from that in the PBB. The maximum CA production in the 20-L air-jacketed PBB was 124.0±19.2 mg g–1DS.

Prediction of effective elasticity coefficients of composite biofuel [Elektronička građa] / Vasyl Klymenko, Volodymyr Kravchenko, Vasyl Gutsul, Viktoriya Kravchenko, Viacheslav Bratishko. - Ilustr., graf. prikazi.
Bibliografija: 29 jed. - Summary. - It is suggested that fuel pellets made of composites based on solid plant waste should be considered as stochastic systems that are anisotropic in microvolumes but isotropic in the entire structure, i.e. quasi-isotropic in volume. Based on this hypothesis and the analysis of the known micromechanical models for forecasting physical and mechanical constants of composite materials, the expediency of using the Reuss-Voigt and Hashin-Strickman models to determine the effective elastic coefficients of composite biofuels is substantiated. The results of calculations made on these models for a number of two-component biofuel pellets are given. An experimental evaluation of effective Young's modulus and Poisson's ratio for two-component pellets with "straw + brown coal" composition was carried out. The obtained results of experimentally determined values of coefficients satisfactorily correspond to their calculated values: deviations are up to 26%. The Reuss-Voigt model was used in the calculations because the conditions required for the application of the Hashin-Strickman model are not met for composite pellets consisting of straw and brown coal. The results of the study will be useful in calculating or selecting press equipment for the production of quality fuel pellets from composites based on solid plant waste.

Divided wall column modeling and simulation in an open-source environment [Elektronička građa] / João Paulo Henrique, Ruy de Sousa Jr., Argimiro Resende Secchi, Mauro Antonio da Silva Sá Ravagnani, Abdessamad Barbara, Caliane Bastos Borba Costa. - Ilustr., graf. prikazi.
Bibliografija: 29 jed. - Summary. - The divided wall column (DWC) can achieve sharp separations of three or more components in a single shell, substituting conventional sequences of two or more binary distillation columns, with lower expenses. Despite these advantages, DWC models are not available in commercial chemical process simulators. To simulate DWC, users must employ instances of conventional column model and couple them in different configurations. In this paper, a DWC model was developed in EMSO (Environment for Modeling, Simulation and Optimization). DWC model was then used for simulating the separation of an equimolar mixture of three hydrocarbons. Results show that, depending on the number of trays, DWC presented energy savings compared to two ordinary distillation columns. Better separation was obtained when the number of divided trays was close to half the number of total trays. However, the liquid and vapor flow rates split into the divided section play a key role in the separation.

The potential of using grapefruit peel as a natural support for yeast immobilization during beer fermentation [Elektronička građa] / Waldir D. Estela-Escalante, Jimy J. Perez-Escalante, Eduardo L. Fuentes-Navarro, Ricardo M. Pinillos-Miñano. - Ilustr., graf. prikazi.
Bibliografija: 42 jed. - Summary. - The potential use of grapefruit peel as support material for yeast immobilization during beer fermentation was evaluated. After conditioning, FTIR analysis revealed a higher quantity of methoxy (–OCH3) groups, suggesting that lignin is the major component of the support. Cell adhesion onto the conditioned support in 12°Plato laboratory malt wort was evaluated, observing a maximal cell adhesion (2.25 · 109 cells/gram of dried support) at 20 h of cultivation, remaining almost constant in the subsequent time points. Evaluations of the fermentative behaviour of the biocatalyst at 15±0.5 °C in a 14°Plato laboratory malt wort indicated good stability in terms of physical integrity (confirmed by SEM observation). The fermentation time was shortened to four days, and the rates of reducing sugar consumption and ethanol production were improved when compared to fermentations carried out with free suspended cells. These results show a promising potential of grapefruit peel as support material in beer fermentation.

Praćenje promjena kemijskih parametara meda ovisno o načinu njegova skladištenja [Elektronička građa] / Marinela Mandić, Paula Sliva, Josipa Krković, Anna Pierobon, Jozica Raljević, Jasna Bošnir, Danijel Brkić, Maja Budeč, Dario Lasić. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Sažetak ; Summary. - Med je po definiciji namirnica kojoj se ništa ne smije dodavati niti oduzimati kako bi zadržala svoja izvorna karakteristična svojstva. Podaci Food Fraud networka govore kako je riječ o hrani koja podliježe sve češćim prevarama potrošača, odnosno krivotvorenju. Med je specifičnog kemijskog i nutritivnog sastava koji mu daju status visokovrijedne hrane. Taj sastav, osim krivotvorenjem sastojaka, može se ugroziti i njegovim neadekvatnim skladištenjem ili pogrešnom manipulacijom tijekom prerade i prodaje. Cilj je ovoga projekta pratiti promjene osnovnih parametara kvalitete meda kao što su kiselost, elektrovodljivost, aktivnost dijastaze i količina hidroksimetilfurfurala (HMF), koji se mijenjaju s duljinom skladištenja, temperaturom i izloženošću meda Sunčevoj svjetlosti. Istraživanjem je utvrđeno da različiti uvjeti skladištenja meda povezani s promjenom temperaturnog režima imaju utjecaj na promjenu kvalitete meda. Ukupno je analizirano osam uzoraka meda (pet uzoraka meda bagrema i tri uzorka cvjetnog meda), a dobiveni rezultati prikazuju prosječne vrijednosti svih analiziranih uzoraka. Najveće promjene utvrđene su kod dijastaze i HMF-a. Med je skladišten na temperaturi od –20 °C, 0 °C, 20 °C te na temperaturi od 40 °C i 60 °C. Rezultati ukazuju da izlaganje meda višim temperaturama utječe na smanjenje aktivnosti dijastaze ispod 8DN. Jednako tako, rezultati ukazuju da vrijednosti HMF-a pri visokim temperaturama rastu i ako je izloženost meda visokim temperaturama dulja, vrijednosti HMF-a prelaze maksimalne vrijednosti (40mg/kg). Stoga je od velike važnosti da se pri distribuciji i skladištenju meda vodi računa o izloženosti meda utjecaju direktne svjetlosti i temperature okoliša u kojem se med skladišti kako bi se sačuvale prirodne vrijednosti meda. Potrebno je radi zaštite potrošača med skladištiti izvan dohvata Sunčeve svjetlosti i visokih temperatura, a sve u cilju zaštite zdravlja ljudi. - Honey is, by definition, a product to which nothing must be added in order to retain its original properties. Data from Food Froud Network indicates that honey is food which is more and more submitted to chemical counterfeiting by manufacturers and consumer fraud. Honey is of specific chemical and nutritional structure, which gives it its status as food of high value. Besides chemical counterfeit, the sole structure of honey can be jeopardized by leaving it in glass containers too long, since it expiration date is two years after packaging. The purpose of this project is to monitor the honey quality parameters, like acidity, electrical conductivity, diastasis activity and amount of hydroxymethylfurfural (HMF). These parameters alter with length of time the honey is being kept in a container, as well as temperature and sunlight exposure. The study has found different conditions of honey storage, related to the evaluation of the temperature regime, have an impact in honey’s quality change. In total, eight samples of honey were analized (five samples of acacia honey, three samples of flower honey), the results show the average values of all analized samples. Major changes were found in diastasis activity and HMF, which can affect the health benefits of honey. Honey was stored at the temperature of -20 °C, 0 °C, 20 °C, 40 °C and 60 °C. The results show that exposure of honey to higher temperatures impacts upon reduction of diastasis activity below 8 DN. Likewise, the results show that the amount of Hydroxymethylfurfural (HMF) at high temperatures increases, and the longer the exposure of honey is to higher temperatures, the amount of HMF exceeds the maximum values (40 mg/kg). Therefore, it is of great importance that during the distribution and storage of honey, special attention is paid on sunlight and high temperature exposure, in order for natural values of honey to be preserved.

Bibliografija: 22 jed. - Summary ; Sažetak. - This study analyses the extraction process parameters of huracrepitan seed oil using the Adaptive Neuro-Fuzzy Inference System (ANFIS) and Artificial Neural Network (ANN). The experiments were conducted at temperature (60–80 °C), time (4–6 h), and solute/solvent ratio (0.05–0.10) with output parameter as oil yield. Sensitivity analysis shows that temperature and time had the most significant effect on the oil yield. The oil yield estimation performance indicators are: ANN (R2 = 0.999, MSE = 5.63192E-13), ANFIS (R2 = 0.36927, MSE = 0.42331). The results show that ANN gave a better prediction than ANFIS. - Ovom studijom analizirani su procesni parametri ekstrakcije ulja iz sjemenki biljke Hura crepitans primjenom prilagodljivog neuroneizrazitog (neuro-fuzzy) sustava zaključivanja (ANFIS) i umjetne neuronske mreže (ANN). Pokusi su provedeni pri temperaturi 60 – 80 °C, vremenu 4 – 6 h i omjeru otopljene tvari/otapala 0,05 – 0,10 s prinosom ulja kao izlaznim parametrom. Analiza osjetljivosti pokazala je da su temperatura i vrijeme najznačajnije utjecali na prinos ulja. Pokazatelji procjene učinka prinosa ulja su: ANN (R2 = 0,999, MSE = 5,63192E-13), ANFIS (R2 = 0,36927, MSE = 0,42331). Rezultati su pokazali da je ANN dao bolje predviđanje od ANFIS-a.

Bibliografija: 15 jed. - Summary ; Sažetak. - Transesterification of vegetable oil with ethanol in the presence of fine metal oxide particles as catalysts has been investigated. Zinc and nickel(II) oxides were shown to have the highest catalytic activity. In their presence, the conversion of sunflower oil triglycerides, after 150 min, reached 95.3 and 94.2 %, respectively. The optimal mass fraction of zinc oxide catalyst was found to be 0.25–0.31 %. In the presence of zinc oxide, with mass fraction of water in ethanol of 5 and 10 %, the conversion of triglycerides was 98.5 and 94.8 %, respectively. - Ispitana je transseterifikacija biljnog ulja etanolom u prisustvu sitnih čestica metalnih oksida kao katalizatora.

Bibliografija: 57 jed. - Sažetak ; Summary. - Komina masline kao ostatna materija u prehrambenoj industriji ne ubraja se u opasni otpad ili otpad općenito. To je potencijalni problem zbog njezinih određenih komponenata koje negativno utječu na ekosustav, a osobito na vodene organizme i biljke. Uslijed neadekvatnog odlaganja, spojevi komine bivaju isprani i procjeđivanjem dospijevaju u tla i podzemne vode gdje uzrokuju onečišćenja. Tema privlači dodatan interes zbog potencijala iskorištavanja komine masline u raznorazne svrhe, te je predmet mnogih znanstvenih istraživanja današnjice. - Olive pomace is a residue substance in the food industry. It is not considered a hazardous waste or even a waste in general. This is potentially problematic because olive pomace contains certain compounds that can have a negative impact on the ecosystem, especially on aquatic organisms and plants. In case of inappropriate disposal, these toxic compounds may be leached into the soil and groundwater. This topic attracts additional interest due to the potential of olive pomace. Nowadays, olive pomace can be used for various purposes, which are a frequent subject of a lot of scientific research.

Artificial neural network models for prediction of density and kinematic viscosity of different systems of biofuels and their blends with diesel fuel [Elektronička građa] : comparative analysis / Souad Belmadani, Salah Hanini, Maamar Laidi, Cherif Si-Moussa, Mabrouk Hamadache. - Graf. prikazi.
Bibliografija: 28 jed. - Summary ; Sažetak. - In the present article, two models based on the artificial neural network methodology (ANN) have been optimised to predict the density (ρ) and kinematic viscosity (μ) of different systems of biofuels and their blends with diesel fuel. An experimental database of 1025 points, including 34 systems (15 pure systems, 14 binary systems, and 5 ternary systems) was used for the development of these models. These models use six inputs, which are temperature (T) in the range of −10 – 200 °C, volume fractions (X1, X2, X3) in the range of 0–1, and to distinguish these systems, we used kinematic viscosity at 20 °C in the range of 0.67–74.19 mm2 s–1 and density at 20 °C in the range of 0.7560–0.9188 g cm–3. The best results were obtained with the architecture of {6-26-2: 6 neurons in the input layer – 26 neurons in the hidden layer – 2 neurons in the output layer}. Results of comparison between experimental and simulated values in terms of the correlation coefficients were: R2 = 0.9965 for density, and R2 = 0.9938 for kinematic viscosity. A 238 new database experimental of 4 systems (2 pure systems, 1 binary system, and 1 ternary system) was used to check the accuracy of the two ANN models previously developed. Results of prediction performances in terms of the correlation coefficients were: R2 = 0.9980 for density, and R2 = 0.9653 for kinematic viscosity. Comparison of validation results with those of the other studies shows that the neural network models gave far better results. - U ovom članku dva modela zasnovana na metodologiji umjetne neuronske mreže (ANN) optimizirana su za predviđanje gustoće (ρ) i kinematičke viskoznosti (μ) različitih sustava biogoriva i njihovih mješavina s dizelskim gorivom. Za razvoj tih modela upotrijebljena je eksperimentalna baza podataka od 1025 točaka, uključujući 34 sustava (15 čistih sustava, 14 binarnih sustava i 5 ternarnih sustava). Ti modeli koriste šest ulaza: temperatura (T) u rasponu od −10 do 200 °C, volumni udjeli (X1, X2, X3) u rasponu 0 – 1, a za razlikovanje tih sustava korištena je kinematička viskoznost pri 20 °C u rasponu 0,67 – 74,19 mm2 s–1 i gustoća pri 20 °C u rasponu 0,7560 – 0,9188 g cm–3. Najbolji rezultati dobiveni su arhitekturom {6-26-2: 6 neurona u ulaznom sloju – 26 neurona u skrivenom sloju – 2 neurona u izlaznom sloju}. Rezultati usporedbe eksperimentalnih i simuliranih vrijednosti u smislu korelacijskih koeficijenata bili su: R2 = 0,9965 za gustoću i R2 = 0,9938 za kinematičku viskoznost. Za provjeru točnosti dva prethodno razvijena modela ANN upotrijebljeno je 238 novih eksperimentalnih baza podataka s 4 sustava (2 čista sustava, 1 binarni sustav i 1 ternarni sustav). Rezultati performansi predviđanja s obzirom na korelacijske koeficijente bili su: R2 = 0,9980 za gustoću i R2 = 0,9653 za kinematičku viskoznost. Usporedba rezultata validacije s rezultatima drugih studija pokazuje da su modeli neuronske mreže dali znatno bolje rezultate.

Istraživanje utjecaja temperature na promjenu kvalitete maslinovog ulja [Elektronička građa] / Paula Sliva, Marinela Mandić, Josipa Krković, Jozica Raljević, Anna Pierobon, Sonja Serdar, Jasna Bošnir. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Sažetak ; Summary. - Maslinovo ulje visokovrijedna je i kvalitetna namirnica te osnova svake mediteranske prehrane, ali i šire. Sama kvaliteta maslinova ulja, osim načina proizvodnje, uvjetovana je i načinom čuvanja. Svjesni smo činjenice da su maslinova ulja često izložena utjecaju svjetlosti i visokim temperaturama, koje znatno mogu utjecati na njegovu kvalitetu, kako kod proizvođača i distributera tako i kod samih potrošača. Cilj je ovoga rada u laboratorijskim uvjetima simulirati uvjete temperaturnih režima te duljine ekspozicije maslinovih ulja, prateći njihov utjecaj na parametre kvalitete ulja kao što su ukupna kiselost ulja, peroksidni broj, K-broj te promjenu sastava masnih kiselina, uključujući i promjenu senzorskih svojstava. Analizama je utvrđeno da temperatura i način skladištenja imaju znatan utjecaj na promjenu kvalitete ulja, osobito kada je riječ o ukupnoj kiselosti ulja i peroksidnom broju. Stoga je od iznimne važnosti da se ulje skladišti u prikladnoj ambalaži, odnosno tamnim staklenim bocama te da se skloni od utjecaja direktnih Sunčevih zraka i visoke temperature. - Olive oil is a product of high quality and worth, presenting a basis for the Mediterranean diet, as well as other diets. The high quality of olive oil is not only achieved by the way it is produced, but also the the way is kept. Fact is that olive oil is frequently exposed to high temperatures and sunglight, which can influence its quality just the same with consumers, as with manufacturers and distributers. The aim of this paper is to simulate temperature regimes in a laboratory and measure the length of exposure of olive oil to those high temperatures, paying special attention to the total acid number of the oil, the oil quality parameters, such as the peroxide value, K – value, as well as change in structure of fatty acids, including change of sensory properties. Through analysis it was established that temperature and ways in which olive oil is being kept have significant effect on how the oil quality changes, especially when talking about the total acid number and the peroxide number. That being said, it is extremely important the oil is kept in appropriate containers, those being small glass bottles, as well as moved from direct sunlight and therefore high temperatures.

Membranska filtracija kao ekološki prihvatljiva metoda pročišćavanja sirovog biodizela [Elektronička građa] / Marta Ostojčić, Sanja Brkić, Marina Tišma, Bruno Zelić, Sandra Budžaki. - Graf. prikazi.
Bibliografija: 51 jed. - Sažetak ; Summary. - Biodizel je prvo alternativno gorivo čija su fizikalno-kemijska svojstva regulirana odgovarajućim standardima: američkim ASTM D 6751 i europskim standardom EN 14214. Proces proizvodnje biodizela sastoji se od tri glavne faze: 1) pripreme sirovine, 2) transesterifikacije i 3) obrade produkta reakcije – pročišćavanje sirovog biodizela kako bi se zadovoljile specifikacije koje su navedene u prethodno spomenutim standardima. Proces pročišćavanja sirovog biodizela obično se provodi dvjema tehnikama: vlažnim i suhim pranjem. Najčešće primjenjivani postupak je mokro pranje. Glavni nedostatak u upotrebi vode u procesu pročišćavanja je stvaranje velike količine otpadne vode koja uvelike povećava troškove proizvodnje biodizela nakon čega slijedi sušenje proizvoda, što zahtijeva dodatni utrošak energije i vremena. Najveći nedostatak suhog pranja s različitim ionsko-izmjenjivačkim smolama je nemogućnost uklanjanja glicerola i metanola iz sirovog biodizela do onih granica koje su propisane EN 14214 te problem odlaganja iskorištenih ionsko-izmjenjivačkih smola. Zbog toga se kao alternativa postojećim tehnikama pročišćavanja pojavila primjena membranske tehnologije u procesu pročišćavanja biodizela. Membranska filtracija je ekološki prihvatljiva i zahtijeva manje energije. Membranskom filtracijom može se smanjiti udio glicerola, metanola i vode u biodizelu do količina propisanih standardima. U okviru ovog rada prikazan je kratki pregled mogućnosti primjene ultra i/ili mikrofiltracije u procesu pročišćavanja biodizela. - Biodiesel is the first alternative fuel the physicochemical properties of which are regulated by appropriate standards: American ASTM D 6751 and European standard EN 14214. The process of biodiesel production consists of three main phases: 1) preparation of feedstock, 2) transesterification, and 3) processing of the reaction product – purification of crude biodiesel to meet the specification provided by the previously mentioned standards. The purification process of crude biodiesel is usually carried out by two notable techniques: wet and dry washing. The most commonly used process is wet washing. A major drawback in the use of water in purification process is the generation of a large amount of wastewater that greatly increases biodiesel production costs, followed by drying of the product, which requires an additional amount of energy and is time consuming. The greatest disadvantage of dry washing using different ion-exchange resins is the inability to remove glycerol and methanol from crude biodiesel to those limits prescribed by EN 14214, followed by the disposal problem of spent ion-exchange resins. Because of the aforementioned, the use of membrane technology in the process of biodiesel purification has appeared as an alternative for the existing purification techniques. The membrane filtration is environmentally friendly and requires less energy. By membrane filtration, the glycerol, methanol, and water contents in biodiesel can be decreased to the amounts prescribed by the standards. In the frame of this review article, the short overview of the possibility of using ultra- and/or micro-filtration in the purification process of biodiesel is presented.

CAD based electric transporter path planning and production storage optimization using genetic algorithm - industrial case study [Elektronička građa] / Miha Kovačič, Goran Đukić, Brigita Gajšek, Klemen Stopar. - Ilustr., graf. prikazi.
MOTSP 2020 - International Conference Management of Technology - Step to Sustainable Production, 30th September - 2nd October 2020, Bol, island Brač (Croatia). - Bibliografija: 25 jed. - Summary. - Štore Steel Ltd. is one of the largest flat spring steel producers in Europe. There are two production lines after rolling – one for flat bars and the other for round bars. The flat bars production generally consists of visual examination, straightening and cutting operation. In addition, heat treatment or magnetic particle testing could be conducted. On the other hand, the round bars production consists generally of straightening, automatic control line control, chamfering and cutting. In addition, heat treatment is possible. For manipulation of the material in the rolling plant, the electric transporter and several cassettes are used. In the paper path planning and production storage optimization (i.e. storage spaces for cassettes) were conducted using genetic algorithm. The production storage is actually the space between main transport passage and individual operations. In the research the universal system using CAD geometry is presented where AutoCAD environment and in-house developed AutoLISP system were used. The production storage – storage spaces for cassettes (location and orientation) with corresponding electric transporter trajectories are represented as CAD objects and thus form individual solution/organism. The organisms undergo simulated evolution. The results of the evolution are compared with actual production storage in the steel plant.

The effect of the holding pressure profile on the metal injection molded component dimensions after sintering [Elektronička građa] / Emir Šarić, Samir Butković, Muhamed Mehmedović. - Ilustr.
Bibliografija: 13 jed. - Abstract. - The volumetric flow rate (injection velocity) and the holding pressure are metal injection molding (MIM) parameters that have a strong influence on the green parts density and density homogeneity, but their effect on sintered dimensions after sintering is still to a large extent unexplored. To reveal the relationship between the injection molding parameters and sintered dimensions, ring-shaped components were injection molded by using different values of injection velocities in combination with a rump-down and rumpup holding pressure profile. Afterwards, the green components were catalytically debound and sintered in the nitrogen (N2) atmosphere. Finally, the component dimensions: the height, inner and outer diameter were measured by using a coordinate measuring machine. The ready-to-mold granules Catamold 310N made of heat resistant stainless steel X40CrNiSi 25-20 (according to the EN standard) powder and polyacetal based binder were used. The results showed that the interaction between the injection velocity and the holding pressure profile can be used to systematically adjust shrinkage after sintering. This approach is based on the dependence of the binder crystallization temperature on pressure, when the powder/binder proportion changes with the injection velocity.

Investigation of wear behavior of particle reinforced AL/B4C composites under different sintering conditions [Elektronička građa] / İsmail Topcu. - Ilustr.
Bibliografija: 30 jed. - Abstract. - In this study, the effects of different sintering conditions of boron carbide reinforced to aluminum matrix powder on microstructure, density and wear resistance by a mechanical alloying method were researched. Powders produced by mechanical alloying for eight hours at the atrial shaft were compressed with a cold isostatic press die under 350 MPa to obtain cylindrical composite specimens. The raw samples were sintered in high purity argon at 600, 625, 650 °C for 90 minutes. The wear behavior of the Al/B4C metal matrix composite was studied using a pin-on-disk wear tester. Under favorable conditions, it has been observed that reinforced boron carbide wear can be reduced by more than two decades. Various investigations have been made to relate this improved wear performance to reinforcement ratios. Aluminum abrasion test results showed that different types of abrasion occurred and that the abrasion resistance was increased by the change of the bubble rate. In the experimental studies that were carried out, it was observed that wear resistance increased with the proportion of boron carbide reinforced directly by the weight, and especially with a 15% B4C ratio depending on the increased reinforcement ratio.

Preliminary research on influence of welding parameters strength at welded joints in ribbed reinforcing steel [Elektronička građa] / Željko Bilić, Ivan Samardžić, Nedjeljko Mišina, Katarina Stoić. - Ilustr. ; graf prikazi.
Bibliografija: 6 jed. - Abstract. - As already known, no proper control or process control parameter which absolutely guarantees a high level quality of joints made by electro-resistive welding has been established so far, especially when all possible parameters are taken into account during the welding process. Due to the process of butt-welding being very short-lived, ensuring quality of the joints is a difficult and under-researched problem. The application of non-destructive testing methods to the control interface joints is also not reliable. Therefore, further research in this area should concentrate on studying the influence of basic welding parameters, and calculating their direct or indirect impact can serve to achieve a highquality welded joint with for practice sufficient accuracy.

Study on deformation behavior of non-hardenable austenitic stainless steel (grade X5CrNi18-10) by hot torsion tests [Elektronička građa] / Imre Kiss, Vasile Alexa. - Ilustr., graf. prikazi.
Bibliografija: 24 jed. - Summary. - The steel's deformation resistance, in which high strain rates have an important influence on the mechanism of failure, might be obtained from a suitably instrumented torsion test. Determination of stainless steel deformability by hot torsion test is the only method that allows obtaining large deformations along the length of the test specimen, so it is mainly used to determine the characteristics at large plastic deformations. By this method, the hot deformability of stainless steel is determined by subjecting to hot torsion the cylindrical stainless steel specimens maintained at the deformation temperature in a tubular oven belonging to the Laboratory of Metal Rolling and Plastic Deformation, at the Faculty of Engineering – Hunedoara, University Politehnica Timişoara. For the experimental hot torsion tests, several stainless steel grades were used and included in a large series of studies destined to determining the deformation behavior of steel. Having in view the previous results obtained in the study of deformability characteristics of two stainless steels (hardenable martensitic stainless steel, grade X46Cr13 and non–hardenable ferritic stainless steel, grade X6Cr17), this paper includes the results of the hot torsion tests conducted to find the deformation behavior of the non–hardenable austenitic stainless steel (grade X5CrNi18–10). For analysis of laboratory hot torsion tests results the univariate and multivariate regression analysis was used, estimating the relationships among the hot–testing temperature, torque moment and number of torsions up to the breaking point of the specimens of austenitic stainless steel. Therefore, the optimum range of heating temperatures applied for deforming the studied steels results clearly from the deformability – temperature (plasticity – temperature and deformation resistance – temperature) diagrams.

Study on the deformation behaviour of non-hardenable ferritic stainless steel (grade X6Cr17) by hot torsion tests [Elektronička građa] / Imre Kiss, Vasile Alexa. - Ilustr., graf. prikazi.
Bibliografija: 16 jed. - Summary. - The knowledge about the characteristics of deformability (deformation resistance and plasticity) has for the technologist, as well as for the designer and researcher, a great practical significance, because they are important elements in establishing a correct technological process. The change of deformation conditions existing in the industrial process, such as the temperature and rate of deformation, are difficult to consider for correcting the deformability determined by testing. The chemical composition of the material influences the plasticity and its deformation resistance both by the nature and distribution of the alloying elements and by the phase transformations they produce. In this paper, through "deformability", we cover all properties characterizing the deformation behaviour of alloys. In this sense, "deformation resistance" is expressed through the unit strain required to produce a certain degree of plastic deformation, under the conditions of a particular diagram of tensions, deformations and deformation rates, in the absence of external friction forces. Plasticity, being the ability of metallic materials to deform plastic under the action of external forces, is influenced by a number of material characteristics (chemical composition, structure) and other factors characteristic of the deformation (temperature, degree and speed of deformation, applied mechanical scheme). Plasticity is characterized, in the torsion test, by the number of rotations made by the specimen until breakage. A number of methods have already been used for the study of deformability. This study includes the results of hot torsion tests conducted to find the plasticity and deformability characteristics of ferritic stainless steel (non–hardenable stainless steel, grade X6Cr17), which is a flexible grade of the stainless steel family with properties closely matching those of the more popular and expensive austenitic grade.

3D printing in the apparel sector [Elektronička građa] : how environmentally sustainable is it? / Belinda Carp. - Ilustr.
Summary. - 3D printing is a process of making three dimensional (3D) solid objects from a digital file. The object is made using an additive process, which means that successive layers of material are laid down until the object is created. Each of these layers can be seen as a thinly sliced horizontal cross-section of the eventual object. The process enables complex shapes to be produced, using less material than in traditional manufacturing methods.3D printing processes are being used in manufacturing, medicine, architecture, custom art and design. Appli-cations in textiles range from fashion and sportswear to medical devices and aerospace.

Additive manufacturing of polymer moulds for small-batch injection moulding [Elektronička građa] / Damir Godec, Tomislav Breški, Miodrag Katalenić. - Ilustr.
Bibliografija: 15 jed. - Abstract. - In case of small-batch production, applications of classic technologies and tools, for e.g. injection moulding and classic moulds are not competitive. Application of additive technologies (AT) for direct production of finally parts can partially reduce deficiencies of classic approach, but there are for e.g. limited number of available materials. Potential solution is application of AT in production of so called bridge moulds for small-batch production from originally requested material for final part. This paper presents PolyJet process of AT and its possible application for production of bridge polymer moulds for injection moulding of small quantity of the moulded parts together with design rules for PolyJet bridge moulds.

Anatomical, chemical and mechanical characteristics of beech wood degraded by two pleurotus species [Elektronička građa] = Anatomska, kemijska i mehanička svojstva bukova drva degradiranoga gljivama roda Pleurotus / Yaghoob Azimi, Mohsen Bahmani, Ali Jafari, Hamid Reza Riyahi Bakhtyari. - Ilustr. ; graf. prikazi.
Bibliografija: 41 jed. - Abstract ; Sažetak. - The aim of this study was to determine the destructive capabilities of the two white rot fungi Pleurotus cornucopiae (Pc) and P. eryngii (Pe) compared with the standard fungus Trametes versicolor (Tv) on beech wood samples after 60 days of incubation. Understanding of the white rot decay is important as it is necessary for the development of effective solutions for wood protection. Measurements of mass loss, chemical, mechanical properties and light microscopical investigations were conducted prior to and after incubation. Mass loss of samples was found to be 9-22 % depending on fungi species. Impact bending strength is not as sensitive as presumed in classical literature. Light microscopy analysis revealed that decay patterns were similar for both fungi. Wood cell wall thinning, fungal colonization hyphae were also the same for both fungi. Results indicated considerable wood attack by both Pleurotus species, Pc being more destructive than Pe. - Cilj rada bio je utvrditi učinak dviju gljiva bijele truleži – Pleurotus cornucopiae (Pc) i P. eryngii (Pe) – na uzorcima bukova drva nakon 60 dana inkubacije u usporedbi s učinkom standardne gljive Trametes versicolor (Tv). Razumijevanje degradacije drva zbog bijele truleži iznimno je važno za razvoj učinkovitih rješenja zaštite. U pokusu su prije i nakon inkubacije drva provedena mjerenja gubitka mase, kemijskih i mehaničkih svojstava te je obavljeno ispitivanje svjetlosnim mikroskopom. Utvrđeno je da je gubitak mase uzoraka iznosio 9 – 22 %, ovisno o vrsti gljive. Čvrstoća drva na savijanje nije toliko osjetljiva na utjecaj gljiva kao što se navodi u klasičnoj literaturi. Analiza slika dobivenih svjetlosnim mikroskopom pokazala je da su procesi propadanja drva pri zarazi objema gljivama slični. Stanjivanje stijenki drvnih stanica i hife kolonizacije obiju gljiva također su bile jednake. Rezultati su pokazali znatnu degradaciju drva napadnutoga gljivama roda Pleurotus, s tim da je gljiva Pc destruktivnija od gljive Pe.

Appraisal of bed linen performance with respect to sleep quality [Elektronička građa] / Tanima Chanda, Meenakshi Ahirwar, Bijoya Kumar Behera. - Graf. prikazi.
Bibliografija: 20 jed. - Summary. - Bed linen is the material laid above the mattress of a bed that serves various purposes – hygiene, warmth, protection of the mattress – and also has a decorative effect in the room. According to several studies, the type of bed linen used for our sleep has a direct effect on our health; in other words, sleep quality is the ultimate performance indicator of bed linen cloth. In this research work, a relationship between bed linen properties and sleep quality was established. Bed linens serve as a basic requirement for sleep, and assessing the right kind of sheet is an important aspect to look into. Analyzing the basic properties of bed linen is an important exercise to perform in order to provide the user with the best-quality sleep. This research focuses on deriving an equation that can be applied to calculate the objective measurement of sleep quality with respect to bed linen properties by developing a bed linen sleep quality index. Questionnaires were designed and subjective evaluation method was followed. A panel of experts was considered for a subjective rating of bed linen properties, their weightage, ranking and bed linen fabrics assessment. Coefficient of concordance was calculated to determine the agreement among the judges and a discriminant analysis was also carried out to determine the variation of the individual rating for a particular property. The results showed a high correlation between the subjective index and the objective index for the bed linen fabric samples. Thus, the objective sleep quality index could be estimated well.

Bio-based methods with potentials for application in wooden furniture industry [Elektronička građa] = Biološke metode s potencijalom za primjenu u proizvodnji namještaja od drva / Karin Hrovatin, Jasna Hrovatin.
Bibliografija: 75 jed. - Abstract ; Sažetak. - Furniture market is shifting towards green and innovative products. The use of bio-based methods in wooden furniture industry presents a big potential for the development of materials with new characteristics, of unique furniture items, and can reduce the environmental impact. Bio-based methods can be used for wood protection and decoration, fibre board production, and development of new wooden materials, such as wood hybrids and functionalised wood. The bio-based methods, investigated for their potentials in wood industry, include the use of living organisms, natural products, and biomimicry. Despite ongoing developments there are still major drawbacks associated with many of these technologies: unreliability and inadequate efficiency of the methods, inadequate mechanical properties or dimensional stability of the final products, and high costs. Thus, further developments are needed. In this review, we present the existing and arising bio-based methods with potential in wooden furniture production. Furthermore, we shortly present their marketing potential. - Tržište namještaja sve se više pomiče prema zelenim i inovativnim proizvodima. Primjena bioloških metoda u proizvodnji namještaja od drva znači velik potencijal za razvoj materijala novih svojstava te za proizvodnju jedinstvenih predmeta namještaja. Osim toga, uvođenje bioloških metoda u industriju namještaja može pridonijeti i smanjenju štetnog utjecaja na okoliš. Biološke se metode mogu primijeniti u zaštiti i dekoraciji drva, u proizvodnji ploča vlaknatica i u razvoju novih drvnih materijala kao što su drvni hibridi i funkcionalizirano drvo. Spomenute metode, čiji se potencijal primjene u proizvodnji namještaja istražuje, uključuju biotehnologiju, uporabu prirodnih proizvoda i biomimikriju. Unatoč stalnom razvoju, još postoje znatni nedostatci povezani s primjenom tih tehnologija. To su složenost ili nepouzdanost metoda, neadekvatna mehanička svojstva ili dimenzijska stabilnost konačnih proizvoda te visoki proizvodni troškovi. Stoga je potrebno i dalje razvijati te metode radi njihove primjene u proizvodnji namještaja. U ovom su radu predstavljene razvijene biološke metode i one koje su u fazi razvoja a imaju potencijala za primjenu u proizvodnji namještaja od drva. Usto je ukratko opisan i njihov marketinški potencijal.

Changes in customer preferences for furniture in Slovenia [Elektronička građa] = Promjene sklonosti kupaca namještaja u Sloveniji / Matej Jošt, Vladislav Kaputa, Martina Nosáľová, Andreja Pirc Barčić, Ivana Perić, Leon Oblak. - Graf. prikazi.
Bibliografija: 34 jed. - Abstract ; Sažetak. - In the last decade, the Slovenian furniture industry market has experienced a number of changes, especially with the arrival of new retailers on the market. The situation is such that furniture manufacturers and retailers are still trying to determine the best ways to adjust to new customer demands. A well known thing is that customer satisfaction is the key component for the success of the business. In order for companies to be more successful, it is important to get better insight into customers’ needs and wants. In line with this, the purpose of this study, which compare the surveys conducted in 2010 and 2019, was to observe and analyse changes in the preferences of customers for furniture: materials, attributes, and styles when deciding on new furniture in Slovenia. The results of this research showed that customers’ preferences for furniture materials have changed in the last decade. Similarly, the factors that influence their purchase decisions when buying interior and exterior furniture have changed as well. It was found that wood was widely preferred as a furniture material among the respondents in both years studied. - U posljednjem desetljeću slovensko je tržište namještaja doživjelo mnoge promjene, posebice ulaskom stranih trgovaca. Stoga proizvođači namještaja i trgovci i dalje pokušavaju odrediti najbolje načine prilagodbe novim zahtjevima kupaca. Općenito je poznato da je zadovoljstvo kupaca ključna komponenta za uspjeh poslovanja. Kako bi tvrtke bile uspješne, važno je imati što bolji uvid u potrebe i želje kupaca. U skladu s tim, cilj ovog istraživanja, koje uspoređuju ankete provedene 2010. i 2019., bila je usporedba i analiza promjena sklonosti kupaca pri odabiru i kupnji namještaja, i to u smislu materijala, svojstava i stila. Rezultati provedenog istraživanja pokazali su da su se sklonosti ispitanika u odabiru materijala namještaja u posljednjem desetljeću promijenile. Osim toga, promijenili su se i činitelji koji utječu na njihove odluke pri kupnji namještaja za vanjsku ili unutarnju upotrebu. Ispitivanja su pokazala da je drvo 2010. bio vrlo poželjan materijal za izradu namještaj, a to je i danas.

Characterizati on of sisal/polypropylene composites treated with plasma [Elektronička građa] / B. A. Muralidhar. - Ilustr., graf. prikazi.
Bibliografija: 16 jed. - Summary. - In this study, sisal/polypropylene composites were experimentally investigated for their flexural, thermal and water absorption characteristics. The effect of oxygen (O), argon (Ar) and ammonia (NH3) plasmas on the surface of the sisal fibre as well as the effect of the sisal fibre content on the above mentioned properties was studied. The composite laminates (4 mm thick) were processed by hand lay-up technique by using a compression moulding machine, with the mould temperature of 165oC and the pressure of 6.89 x 102 kPa for 15 minutes. Specimen preparation and testing were carried out as per ASTM standards. Flexural data obtained showed that the plasma-treated sisal fibre-reinforced polypropylene offered superior flexural properties compared to untreated laminates, which indicated better adhesion between the sisal fibre and the untreated polypropylene matrix. Thermal investigations revealed that the sisal/polypropylene composite had its thermal stability in between that of the fibre and the matrix. Furthermore, the water absorption studies indicated that plasma treatment decreased the water uptake of the laminates, thereby leading to better fibre-matrix adhesion. Morphological studies were carried out by using SEM to complement the results.

Chromium adsorption on banana rachis adsorbent from tannery wastewater [Elektronička građa] : optimization, isotherm, kinetics and desorption studies / Sofia Payel, Md. Abul Hashem, Mrinmoyee Sarker, Md. Shahruk Nur-A-Tomal. - Graf. prikazi.
Bibliografija: 44 jed. - Summary. - This study investigates the banana rachis adsorbent for adsorption characterization, removal, and recovery of the chromium ion from the chrome tanning wastewater. The batch analysis was conducted to find out an adsorbent dose, contact time, relative pH of the aqueous solution, and initial and final chromium value in the filtrate. The equipped adsorbent was studied by the Fourier transform infrared spectroscopy (FT-IR) analysis to reveal the associated functional groups during adsorption. Batch adsorption examination reveals the optimum conditions of 3 g adsorbent input for 75 mL wastewater at 15 min contact time. The adsorption mechanism showed chromium removal 99.64% with the obtained reduction of biochemical oxygen demand (BOD), chemical oxygen demand (COD), and chloride (Cl-) 96.65%, 93.18%, and 59.62%, respectively. The adopted method followed the pseudo-second-order kinetics and Freundlich isotherm for physical adsorption. Primary desorption studies exhibit a scope for the reuse of chromium from the adsorbed adsorbent. Moreover, in comparison with other studies, the study discloses that banana rachis might be utilized as a feasible adsorbent to be adopted in industrial wastewater treatment, especially chrome tanning wastewater in the tannery.

Clothing and textile sustainability [Elektronička građa] : current state of environmental challenges and the ways forward / Sarif Patwary. - Graf. prikazi.
Bibliografija: 63 jed. - Summary. - The global clothing and textile industry is facing immense criticism due to its enormous environmental pollution. While demonstrating a slow adoption, brands, retailers, and manufacturers are recognizing the unsustainable nature of the industry. Consumers, too, are also becoming more aware of the environmental issues of the industry. Policymakers are coming up with relevant regulations to set the industry into a sustainable direction. However, the plethora of information, ideas, suggestions, and strategies make it difficult to get a holistic idea of the environmental sustainability challenges that the industry is facing and the necessary actions it should take. This paper reviews the current state of environmental challenges, and the required actions articulated in the literature as related to the clothing and textile industry. Based on this review, suggestions are made for the key stakeholders of the clothing supply chain, and the profile of an environmentally sustainable clothing item is examined. The review revisits the complexity of the clothing supply chain and stresses the urgency of expediting actions.

Comparison of visual and instrumental assessment of colour differences on finished wooden surfaces [Elektronička građa] = Usporedba vizualne procjene i izmjerene promjene boje površinski obrađenog drva / Matjaž Pavlič, Marko Petrič. - Graf. prikazi.
Bibliografija: 29 jed. - Abstract ; Sažetak. - Staining of wood with various substances and processes is an important part of surface finishing of wood. Colour differences as a result of staining and of exposure of coloured wood during its utilisation are usually evaluated by instrumental measurements. However, the measurement results can show something else compared to what our naked eye can see. Due to inhomogeneity of wood, this discrepancy can be even greater in the case of finished surfaces. The aim of our research was to evaluate distinctions between visual perception and numerically determined colour differences on differently finished wooden surfaces, to get information at which starting point the colour difference becomes visible, and to establish whether it is related to the nature of the surface. We established that the visual assessment is influenced by many factors and that there is a correlation between visual and instrumental assessments. The colour difference ΔE* of 0.5 should be considered as a value when it starts to become visible, and at the value of 2.0, observers already considered the colour difference as a different colour. It was stated that we have some tolerance in perceiving the colour change. This tolerance is more expressed in the case of transparent coating systems. - Premazivanje drva različitim sredstvima i primjenom različitih postupaka važan su dio površinske obrade drva. Promjene boje kao rezultat premazivanja i izlaganja obojenog drva tijekom njegove uporabe obično se mjere uređajima. Međutim, izmjereni rezultati pokazuju nešto sasvim drugo od onoga što se vidi ljudskim okom. Kad je riječ o površinskoj obradi drva, razlike između izmjerenih rezultata i onoga što se vidi ljudskim okom mogu se povećati zbog nehomogenosti drva. Cilj istraživanja bio je procijeniti razlike između vizualne procjene i izmjerene promjene boje na površinski obrađenom drvu primjenom različitih tehnika kako bi se utvrdila vrijednost pri kojoj je promjena boje vidljiva te kako bi se utvrdilo ovisi li ona o vrsti površine. Ustanovili smo da na vizualnu procjenu promjene boje utječe velik broj čimbenika i da postoji veza između vizualne procjene i izmjerenih vrijednosti promjene boje. Promjena boje ΔE* od 0,5 vrijednost je pri kojoj promjena boje postaje vidljiva, a promjenu boje od 2 promatrači vide kao različitu boju. Uočeno je da postoji određena tolerancija u percepciji promjene boje, koja je veća pri procjeni promjene boje prozirnih sustava premaza.

Contribution to the evaluation of thermal insulation properties of a simple and a double window in a log building [Elektronička građa] = Doprinos procjeni svojstava toplinske izolacije jednostrukoga i dvostrukog prozora na drvenoj kući / Petr Fait, Pavel Král, Josef Čech, Vladimir Linhart. - Ilustr.
Bibliografija: 16 jed. - Abstract ; Sažetak. - The paper describes the method for the determination and evaluation of thermal insulation properties of various types of windows made from pine wood. The method has been used for a simple and a double window that are parts of a log house in the Czech Republic. Both windows are located in one room. The method for the evaluation of thermal insulation properties consists in determining the boundary conditions of the frame and sash temperature from the interior and exterior. Additionally, the temperature of the window surroundings was measured, at the building envelope. The boundary conditions were measured by different sensors to ensure an accurate setting of the thermographic camera. Based on the values determined, the method calculates the heat transfer coefficient and the temperature factor of the internal surface. Then, the thermal insulation properties of integrated windows can be determined and compared. The priority of this measurement was a basic comparison of thermal insulation properties of two different types of windows located in a log house. This measurement will serve as the basis for a comparison of thermal insulation properties of the same types of windows in different log houses located in regions with different weather conditions. After a comprehensive comparison, based on the results, the right type of window can be recommended with respect to the location of the log house in question. - U radu je opisana metoda određivanja i procjene svojstava toplinske izolacije različitih tipova prozora od borovine. Metoda je primijenjena za ispitivanje svojstava jednostrukoga i dvostrukog prozora postavljenih na drvenoj kući u Češkoj Republici. Oba se prozora nalaze na istoj prostoriji. Metoda procjene svojstava toplinske izolacije sastoji se od određivanje graničnih uvjeta prozora i doprozornika s unutarnje i vanjske strane. Usto, izmjerena je temperatura oko prozora u ovojnici kuće. Granični su uvjeti izmjereni različitim senzorima kako bi se osigurala točna postavka termografske kamere. Na temelju utvrđenih vrijednosti uz pomoć spomenute metode izračuna se koeficijent prolaska topline i toplinski faktor unutarnje površine. Nakon toga se mogu odrediti i usporediti svojstva toplinske izolacije ugrađenih prozora. Prioritet ovog mjerenja bila je usporedba svojstava toplinske izolacije dvaju različitih tipova prozora na drvenoj kući. Provedeno će mjerenje poslužiti kao osnova za usporedbu svojstava toplinske izolacije istih tipova prozora na različitim drvenim kućama koje se nalaze na lokacijama s različitim vremenskim uvjetima. Nakon složene usporedbe na temelju rezultata može se preporučiti odgovarajući tip prozora s obzirom na lokaciju drvene kuće.

Determination of the odour adsorption behaviour of wool [Elektronička građa] / Ebru Yilmaz, Pinar Çelik, Ayşegül Körlü, Saadet Yapar. - Ilustr., graf. prikazi.
Bibliografija: 29 jed. - Summary. - In this study, the adsorption/desorption behaviours of water vapor on wool, as well as of the redolents, such as acetic acid and benzaldehyde, have been investigated. For this purpose, static and dynamic experiments were carried out. Static experiments were conducted to model stagnant environments. In the experiments, wool came into contact with the material to be adsorbed or dry air and the weight increase/decrease was recorded for a certain period of time. The results obtained showed that the wool adsorbed the benzaldehyde very little, whereas the adsorbed amount and the rate were abundantly increased for acetic acid under the same conditions. From these findings, the adsorption capacity of wool for the redolents was tentatively ranked in accordance with their adsorbed amounts as acetic acid>water>benzaldehyde.

Digital development of Slovenian wood industry [Elektronička građa] = Digitalni razvoj slovenske drvne industrije / Jože Kropivšek, Petra Grošelj. - Graf. prikazi.
Bibliografija: 32 jed. - Abstract ; Sažetak. - The research examined the digital development of the Slovenian wood industry, especially the implementation of the concept of Industry 4.0 into practice. Within this, the implementation of specific technological pillars was studied, with the emphasis on smart factories and smart, innovative products. In the empirical part of the research, we prepared a survey and interviewed selected managers and entrepreneurs. We compared answers regarding sub-sectors, the size of the companies and the level of digitalization. The general results show that around half of the surveyed companies are already implementing the Industry 4.0 concept into their businesses, while the rest are beginners when speaking about digitalization. The biggest obstacles to the implementation of the concept are the high investments in equipment and the lack of financial support from the state. The lack of digital competencies, which is especially prevalent among older workers, is another major barrier that businesses face. Only 30 % of the surveyed companies are engaged in the production of smart products. We can conclude that digitalization in the Slovenian wood industry is still at a relatively low level, but with the latest strategic orientations at both the state and business level, this situation will certainly improve in the near future. - U radu je predočeno istraživanje digitalnog razvoja slovenske drvne industrije, posebice istraživanje primjene koncepta Industrija 4.0 u praksi. Unutar toga proučavana je primjena specifičnih tehnoloških stupova s naglaskom na pametne tvornice i pametne, inovativne proizvode. U empirijskom dijelu istraživanja pripremili smo anketu i intervjuirali odabrane menadžere i poduzetnike. Usporedili smo odgovore koji se odnose na podsektore, veličinu poduzeća i razinu digitalizacije. Opći rezultati pokazuju da približno polovica anketiranih tvrtki u poslovanju već primjenjuje koncept Industrija 4.0, dok su ostale tvrtke početnici u digitalizaciji. Najveće su prepreke provedbi koncepta velika ulaganja u opremu i izostanak državne financijske potpore. Nedostatak digitalnih kompetencija, koji je osobito vidljiv među starijim radnicima, dodatna je velika prepreka s kojom se tvrtke suočavaju. Samo 30 % anketiranih tvrtki bavi se proizvodnjom pametnih proizvoda. Može se zaključiti da je digitalizacija u slovenskoj drvnoj industriji još uvijek na relativno niskoj razini, ali s najnovijim strateškim orijentacijama i na državnoj i na poslovnoj razini ta će se situacija u skoroj budućnosti sigurno poboljšati.

Durability and mechanical performance of differently treated glulam beams during two years of outdoor exposure [Elektronička građa] = Trajnost i mehanička svojstva različito obrađenih lameliranih nosača tijekom dvije godine izlaganja u eksterijeru / Davor Kržišnik, Samo Grbec, Boštjan Lesar, Denis Plavčak, Bogdan Šega, Milan Šernek, Aleš Straže, Miha Humar. - Ilustr.
Bibliografija: 37 jed. - Abstract ; Sažetak. - The performance of the composites is influenced by the service life of input raw wood material and used adhesives. The aim of the study was to assess the durability and mechanical performance of glulam beams treated in a different way (thermally modified and/or treated with copper-based wood preservative) and exposed in an outdoor application. Glulam beams (83 mm × 68 mm × 1100 mm), made of three layers of Norway spruce (Picea abies) with PUR adhesives used have been exposed in use class 3.2 in a horizontal position since 4th November 2016. Part of the specimens was equipped with MC sensors. Every year, the degradation was evaluated visually. The dynamic modulus of elasticity was determined by longitudinal vibration, and the static modulus of elasticity using a 4-point bending test. On the smaller specimens, cut from glulams, compressive strength, delamination, and shear strength of adhesive bonds were determined. After two years of exposure, the results indicate that the performance of glulams is determined by the wood modification and applied wood preservative. - Na svojstva kompozita utječu trajnost sirovine i svojstva primijenjenih ljepila. Cilj ovog istraživanja bio je procijeniti trajnost i mehanička svojstva različito obrađenih lameliranih nosača (toplinski modificiranih i/ili impregniranih bakrom) izloženih u eksterijeru. Lamelirani nosači (83 mm × 68 mm × 1100 mm) izrađeni su od tri sloja smrekovine (Picea abies) koji su slijepljeni PUR ljepilom. Nosači su prema klasi uporabe 3.2 izloženi u vodoravnom položaju od 4. studenoga 2016. u trajanju od dvije godine. Na dio uzoraka postavljeni su senzori za mjerenje sadržaja vode u njima. Svake je godine vizualno ocjenjivano propadanje uzoraka. Dinamički modul elastičnosti određen je longitudinalnom vibracijom, a statički modul elastičnosti savijanjem u četiri točke. Na manjim uzorcima ispiljenima od nosača određena je tlačna čvrstoća, delaminacija i čvrstoća lijepljenog spoja na smicanje. Nakon dvije godine rezultati izlaganja pokazali su da svojstva lameliranih nosača ovise o toplinskoj modifikaciji drva i sredstvu za impregniranje.

Effect of natural resin from wild pistachio trees on physical properties and durability of beech wood [Elektronička građa] : alone and in combination with boric acid = Utjecaj prirodne smole divljeg drva pistacije (same i u kombinaciji s bornom kiselinom) na fizička svojstva i trajnost bukovine / Soheila Izadyar, Yaser Babaei, Davood Efhamisisi. - Graf. prikazi.
Bibliografija: 37 jed. - Abstract ; Sažetak. - This study was carried out to investigate the physical properties and decay resistance of beech wood treated with natural pistachio resin (PR) from Iranian wild pistachio trees (Pistacia atlantica), alone and in combination with boric acid (BA). Wood samples were impregnated with different concentration of PR dissolved in ethanol (3 to 20 %) with vacuum-pressure technology. The combination of PR (20 %) and BA (2 %) was also conducted to evaluate any interaction or synergistic effects. The water absorption, volumetric swelling, and decay resistance against Trametes versicolor fungi, before and after a leaching test (EN 84), were measured on treated and untreated samples. The chemical compositions of PR were also identified by gas chromatography–mass spectrometry (GC-MS) techniques. The chemicals analysis identified more than 20 different compounds in the PR, monoterpenoids being the predominant fraction and α-pinene the major component. The samples treated with a higher concentration of PR showed much higher weight gain percentage (WG%). The results showed that the increase in WG% reduced the average values of water absorption and volumetric swelling of treated samples even after long terms of soaking in water. The decay resistance of the treated samples increased against white rotting fungi as the values of WG% increased. Efficient protection was seen when a combined treatment of PR and BA was used. Even after the leaching process, the weight loss of the treated samples was less than 3 percent. The samples treated with BA alone largely lost their effectiveness against fungal attack after the leaching. The use of PR along with an environmental friendly co-biocide can also be recommended for wood preservation in places that require minimal toxicity. - Cilj ovog rada bio je istražiti fizička svojstva i otpornost na propadanje bukovine tretirane prirodnom smolom pistacije (PR) dobivene iz divljeg drva pistacije koja uspijeva u Iranu (Pistacia atlantica) te kombinacijom smole pistacije i borne kiseline (BA). Uzorci drva vakuumsko-tlačnim su postupkom impregnirani različitim koncentracijama PR-a otopljenoga u etanolu (3 do 20 %). Provedena je i impregnacija uzorka kombinacijom PR-a (20 %) i BA-a (2 %) kako bi se procijenili svi interakcijski i sinergijski učinci. Za tretirane i netretirane uzorke mjerena je upojnost vode, volumetrijsko bubrenje i otpornost na djelovanje gljive Trametes versicolor prije i nakon ispiranja (EN 84). Ujedno je uz pomoć plinske kromatografije s masenom spektrometrijom (GC-MS) utvrđen i kemijski sastav smole (PR). Kemijskom analizom u PR-u je identificirano više od 20 različitih spojeva; momoterpeni su bili dominantna frakcija, a alfa-pinen glavna komponenta. Uzorci tretirani većom koncentracijom PR-a rezultirali su većim dobitkom mase (WG%). Rezultati su pokazali da se s porastom WG% smanjuje prosječna vrijednost upojnosti vode i volumetrijsko bubrenje tretiranih uzoraka, čak i nakon dugotrajnog potapanja u vodi. Otpornost tretiranih uzoraka na djelovanje gljiva bijele truleži povećala se s povećanjem WG%. Učinkovita zaštita primijećena je pri primjeni kombiniranog tretmana PR-om i BA-om; čak je i nakon postupka ispiranja gubitak mase tretiranih uzoraka bio manji od 3 %. Uzorci tretirani samo BA-om nakon ispiranja su uglavnom izgubili otpornost na napad gljiva. Moguće je zaključiti da se za zaštitu drva na mjestima koja zahtijevaju minimalnu otrovnost može preporučiti upotreba PR-a zajedno s ekološki prihvatljivim biocidom.

The effect of sapwood and heartwood differences on mechanical properties of fast-growing tree species [Elektronička građa] = Utjecaj razlika između bjeljike i srži na mehanička svojstva drva brzorastućih vrsta / İbrahim Bektaş, Ahmet Tutuş, Gamze Gültekin. - Graf. prikazi.
Bibliografija: 35 jed. - Abstract ; Sažetak. - In most uses where wood material needs impregnation or dimensional stability is essential, the properties of sapwood and heartwood should be taken into account. Also, due to the structural differences between heartwood and sapwood, differences in the strength of wood materials should be predicted. Therefore, the aim of this study was to reveal the differences between the mechanical properties of sapwood and heartwood of some important fast-growing forest trees. For this purpose, two softwoods (Pinus sylvestris) and (Pinus brutia) and two hardwoods (Populus usbekistanica) and (Eucalyptus grandis) were selected as test trees. Compression strength parallel to grain (CS ǁ), static quality value (IS), bending strength (MOR), modulus of elasticity (MOE), tensile strength perpendicular to grain (TS⊥), shearing strength parallel to grain (SS ǁ), impact bending strength (IBS), dynamic quality value (ID) and Janka hardness values (JH) of sapwood and heartwood of test trees were determined in laboratory studies. The results of the t-test analysis showed that all mentioned mechanical properties of sapwood and heartwood of test trees were separated from each other as significant, except the shear strength of Eucalyptus, dynamic quality values of red pine and Scots pine and Janka hardness value of red pine. Finally, the results of the study revealed that the differences between sapwood and heartwood strength should be taken into account when wood species are used in constructions and other sensitive areas. - U većini primjera uporabe drva u kojima je potrebna impregnacija ili je postojanost dimenzija iznimno važna treba uzeti u obzir različita svojstva drva bjeljike i srži. Usto, zbog strukturnih razlika između srži i bjeljike treba predvidjeti i razlike u njihovoj čvrstoći. Cilj je ovog istraživanja bio utvrditi razlike između mehaničkih svojstava srži i bjeljike nekih važnih brzorastućih šumskih vrsta drva. Stoga su za izradu uzoraka odabrane dvije vrste četinjača (Pinus sylvestris i Pinus brutia) i dvije vrste listača (Populus usbekistanica i Eucalyptus grandis). U laboratorijskim su uvjetima za uzorke drva četinjača i drva listača određena ova svojstva: tlačna čvrstoća paralelno s vlakancima (CS ǁ), vrijednost statičke kvalitete (IS), čvrstoća na savijanje (MOR), modul elastičnosti (MOE), vlačna čvrstoća okomito na vlakanca (TS⊥), smična čvrstoća paralelno s vlakancima (SS ǁ), čvrstoća drva na udarce (IBS), vrijednost dinamičke kvalitete (ID) i tvrdoća po Janki (JH). Rezultati usporedbe uz pomoć t-testa pokazali su da se istraživana mehanička svojstva drva bjeljike i srži znatno razlikuju, osim smične čvrstoće drva eukalipta, dinamičkih vrijednosti kvalitete drva crvenog bora i običnog bora te tvrdoće drva crvenog bora po Janki. Zaključno, rezultati studije pokazali su da je pri upotrebi drva brzorastućih vrsta u graditeljstvu i drugim osjetljivim područjima nužno uzeti u obzir razlike među mehaničkim svojstvima drva bjeljike i srži.

Effects of recycled fiber fines on hand sheet properties of different unbeaten and beaten pulps [Elektronička građa] = Utjecaj finih recikliranih vlakana na svojstva ručno izrađenog papira od nemljevene i mljevene celuloze / Sezgin Koray Gülsoy, Saffet Uysal. - Graf. prikazi.
Bibliografija: 45 jed. - Abstract ; Sažetak. - In this study, 5, 10, and 15 % secondary fines of recycled pulp were added to unbeaten and beaten (28 ºSR) samples of recycled pulp, Turkish Calabrian pine (Pinus brutia Ten.) kraft pulp, and European aspen (Populus tremula L.) kraft pulp. The effects of the addition of fiber fines on hand sheets properties were evaluated. The addition of fiber fines to the unbeaten pulps improved the strength properties of hand sheets. The roughness of hand sheets was also decreased with the addition of fines. When fiber fines were added to the beaten pulps, the type of pulp strongly affected the paper strength properties. The strength properties of beaten pulps of Turkish Calabrian pine and European aspen were decreased with the addition of fiber fines, while the strength properties of beaten pulps of recycled pulp were increased. On the other hand, the air permeance of unbeaten and beaten samples was decreased with the addition of fiber fines. Consequently, the addition of fines to unbeaten and beaten pulps had a more pronounced effect on European aspen kraft pulp and recycled pulp than on Turkish Calabrian pine kraft pulp. Also, the strength of paper made of unbeaten recycled pulp with the addition of 15 % fines was higher than that of fines-free beaten recycled pulp. - U radu je opisano istraživanje u kojemu je mljevenoj i nemljevenoj (28 °SR) recikliranoj celulozi, kraft celulozi od brucijskog bora (Pinus brutia Ten.) i kraf celulozi od jasike (Populus tremula L.) dodano 5, 10 i 15 % sekundarnih finih vlakana reciklirane celuloze. Utvrđeni su učinci dodavanja finih vlakana na svojstva ručno izrađenih papira. Dodatak vlakana nemljevenoj celulozi pridonio je povećanju čvrstoće i smanjenju hrapavosti ručno izrađenih papira. Pri dodavanju vlakana mljevenoj celulozi velik je utjecaj na čvrstoću papira imala vrsta celuloze. Čvrstoća mljevene celuloze od brucijskog bora i jasike dodatkom vlakana se smanjila, dok se čvrstoća mljevene reciklirane celuloze povećala. Usto, dodatkom vlakana smanjena je propusnost zraka mljevenih i nemljevenih uzoraka. Posljedično, učinak dodavanja vlakana mljevenoj i nemljevenoj celulozi bio je veći za kraft celulozu od jasike i recikliranu celulozu nego za kraft celulozu od brucijskog bora. Također, čvrstoća papira od mljevene reciklirane celuloze s dodatkom 15 % vlakana bila je veća od čvrstoće papira od mljevene celuloze bez dodatka vlakana.

Engineering the properties of eco-friendly medium density fibreboards bonded with lignosulfonate adhesive [Elektronička građa] = Dizajniranje svojstava ekološki prihvatljivih ploča vlaknatica srednje gustoće proizvedenih uporabom lignosulfonatnog ljepila / Viktor Savov, Petar Antov. - Ilustr.
Bibliografija: 26 jed. - Abstract ; Sažetak. - Free formaldehyde emissions from wood-based panels, especially in indoor applications, pose serious risks to human health at certain concentrations. Prolonged exposure to formaldehyde can cause adverse health effects including eye, nose and throat irritation, other respiratory symptoms and cancer. As a consequence, new formaldehyde emission limits for composite wood products were established in Europe, USA and Japan. This, together with the stricter environmental legislation are the main driving factors for shifting the scientific and industrial interest from the traditional formaldehyde-based synthetic resins to the new bio-based adhesives for production of eco-friendly wood-based panels. The lignin-based products are one of the most prospective ecological alternatives to the traditional formaldehyde resins. The main interest in lignin is due to its phenolic structure with several favourable properties for the formulation of wood adhesives such as high hydrophobicity and low polydispersity. The present article is aimed at studying the possibilities for using lignosulfonate as an adhesive for the production of eco-friendly MDF. Regression models describing the impact of lignosulfonate concentration and hot pressing temperature on the exploitation properties of MDF panels were developed. The individual and combined impact of both factors was analysed in order to determine the optimal exploitation properties of the panels. - Emisija slobodnog formaldehida iz ploča na bazi drva, posebice primijenjenih u unutarnjim prostorima, u određenim je koncentracijama ozbiljan rizik za zdravlje ljudi. Dulja izloženost formaldehidu može uzrokovati znatne zdravstvene probleme, uključujući iritaciju očiju, nosa i grla, druge respiratorne simptome i rak. Stoga su u Europi, SAD-u i Japanu određene nove granice emisije formaldehida za kompozitne proizvode od drva. To je, zajedno sa strožim zakonodavstvom o okolišu, bio glavni poticaj za prebacivanje znanstvenoga i industrijskog fokusa s tradicionalnih sintetičkih smola temeljenih na formaldehidu na nova prirodna ljepila za proizvodnju ekološki prihvatljivih ploča na bazi drva. Proizvodi na bazi lignina jedna su od najperspektivnijih ekoloških alternativa tradicionalnim formaldehidnim smolama. Glavni razlog zanimanja za lignin jest njegova fenolna strukturas nekoliko povoljnih svojstava za formulaciju ljepila za drvo poput visoke hidrofobnosti i niske polidisperznosti. Cilj ovog rada jest proučavanje mogućnosti uporabe lignosulfonata kao ljepila za proizvodnju ekološki prihvatljivih ploča vlaknatica srednje gustoće (MDF ploča). Razvijeni su regresijski modeli koji opisuju utjecaj koncentracije lignosulfonata i temperature prešanja na svojstva MDF ploča. Analiziran je pojedinačni i kombinirani utjecaj obaju elemenata kako bi se odredila optimalna svojstva ploča.

Enzyme-accelerated acid hydrolysis of untanned proteinaceous wastes from tanning industry [Elektronička građa] / Md. Nur-E-Alam, Nasifa Akter, Kanish Fatema, Md. Abul Kashem Azad, Shimul Chakma, Md. Anwar Arfi en Khan. - Ilustr., graf. prikazi.
Bibliografija: 19 jed. - Summary. - Traditionally, tanning industry has been producing considerable amounts of solid wastes, which raises serious concerns on account of their environmental impact. Out of these, untanned raw trimmings account for about 5-7% of the total quantity of raw materials processed. This waste could be a value-added cheap source of collagen, which has numerous industrial applications if properly and scientifically utilized. This research work deals with the utilization of raw trimmings of solid waste from tanneries in the process of enzymatic hydrolysis, performed by using acetic acid and protease, in order to obtain protein hydrolysate. The hydrolysis was carried out with varying acid concentrations, acid solutions, temperatures and times. The maximum obtained protein hydrolysate was about 88% at 1.5 M acid concentration, 4% enzyme ratio, and 60 °C.

Evaluating suitability of glutaraldehyde tanning in conformity with physical properties of conventional chrome-tanned leather [Elektronička građa] / Md. Minhaz Uddin,, Md. Jawad Hasan, Yead Mahmud, Fatema Tuj-Zohra, Sobur Ahmed. - Ilustr., graf. prikazi.
Bibliografija: 32 jed. - Summary. - Leather manufacturing involves a number of unit processes, out of which tanning is the most important in so far as it converts the putrescible hides/skins into non-putrescible leather. In this study, glutaraldehyde has been exploited as a means to reduce the use of basic chromium sulfate for the production of quality shoe upper crust leather. The paper consists in studying the physical properties of aldehyde-tanned leather and chrome-tanned leather. The aim is to find out the possibility of replacing the wet-blue leather, containing Cr(III) salts, with the glutaraldehyde-tanned wet-white leather. The physical properties of the aldehyde-tanned leather were evaluated, analyzed and compared with the conventional chrome-tanned shoe upper crust leather. Statistical analysis illustrated that the tensile strength, the percentage of elongation, stitch tear strength, Baumann tear strength and grain crack strength of the leather was 211±1 kg/cm2, 38±0.5 %, 89±0.11 kg/cm, 63±0.4 kg/cm and 23±0.4 kg respectively. It was observed that the property of the experimental leather was quite comparable with the conventional chrome-tanned leather and able to meet the requirements of the shoe upper crust leather after re-tanning. The shrinkage temperature of the experimental tanned leather was found to be 87 °C,lower than that of corresponding control, which indicates lesser tanning power of aldehyde. However, the morphology of the aldehyde-tanned leather was quite akin with the conventional leather. This study suggests that using glutaraldehyde in the tanning process in order to minimize the chromium load in the tanning and the re-tanning process during the production of shoe upper crust leather reduces the generation of toxic waste and its impact on the environment.

Evaluation of Rhododendron luteum and Rhododendron ponticum in pulp and paper production [Elektronička građa] = Procjena mogućnosti uporabe biljaka Rhododendron luteum i Rhododendron ponticum kao sirovine za proizvodnju celuloze i papira / Emre Birinci, Ahmet Tutuş, Mustafa Çiçekler. - Graf. prikazi.
Bibliografija: 35 jed. - Abstract ; Sažetak. - In this study, Rhododendron luteum and Rhododendron ponticum were evaluated as raw material for pulp and paper production. 12 different sodium borohydride (NaBH4) added cooking trials were performed for each sample and kraft method was used for pulp production. Pulp properties, such as yield, kappa number and viscosity, and physical properties, such as breaking length and burst index, were determined for each trial. Besides, the effects of active alkali and NaBH4 on the pulp and paper properties were also examined. Optimum cooking conditions were obtained by using 18 % active alkali for NaBH4-free cooking experiments and 0.5 % NaBH4 and 18 % active alkali for NaBH4-added cooking experiments. In NaBH4-added pulping condition, the screened yield, kappa number and viscosity of R. luteum were found to be 43.4 %, 40.1 and 949 cm3/g1, respectively. The respective values for R. ponticum were 41.9 %, 44.5 and 885 cm3/g1. The screened yields of R. luteum and R. ponticum increased by about 2.8 % and 5.3 %, respectively, with 5 % addition of NaBH4 compared to NaBH4-free cooking experiments. Furthermore, with the addition of NaBH4, the kappa numbers decreased while the viscosity increased. The physical properties of the produced papers were also improved by using NaBH4 in cooking liquor. According to the obtained results, it was found that R. luteum and R. ponticum species can be evaluated for pulp and paper production. - U ovom je radu istražena mogućnost uporabe biljaka Rhododendron luteum i Rhododendron ponticum kao sirovine za proizvodnju celuloze i papira. Za svaki uzorak provedeno je 12 različitih ispitivanja kuhanja s natrijevim borhidridom (NaBH4), a celuloza je proizvedena kraft postupkom. Za svako ispitivanje određena su svojstva celuloze poput prinosa, kappa broja i viskoznosti, te fizička svojstva kao što su duljina lomljenja i indeks pucanja papira. Osim toga, ispitani su učinci aktivne lužine i NaBH4 na svojstva celuloze i papira. Optimalni uvjeti kuhanja postignuti su upotrebom 18 % aktivne lužine za eksperimentalno kuhanje bez NaBH4 i upotrebom 0,5 % NaBH4 i 18 % aktivne lužine za eksperimentalno kuhanje s dodatkom NaBH4. U proizvodnji celuloze iz biljke R. luteum s dodatkom NaBH4 utvrđeno je da prinos prosijavanja iznosi 43,4 %, da je kappa broj 40,1, a viskoznost 949 cm3/g, dok su vrijednosti za celulozu dobivenu iz biljke R. ponticum redom 41,9 %, 44,5 i 885 cm3/g. Prinos prosijavanja biljaka R. luteum i R. ponticum uz dodatak 5 % NaBH4 povećao se oko 2,8 % i 5,3 % u usporedbi s eksperimentalnim kuhanjem bez dodatka NaBH4. Nadalje, uz dodatak NaBH4 smanjuju se kappa brojevi, a viskoznosti se povećavaju. Fizička svojstva proizvedenih papira također se poboljšavaju dodavanjem NaBH4 tekućini za kuhanje. Iz dobivenih je rezultata utvrđeno da se biljke R. luteum i R. ponticum mogu upotrebljavati u proizvodnji celuloze i papira.

Bibliografija: 20 jed. - Abstract ; Sadržaj. - In this study, control samples of pine (Pinus slyvestris L.), beech (Fagus orientalis L.) and oak (Quercus petreae L.) species were obtained by using fi ber reinforced finger corner joints. Teknobont 200 epoxy and polyvinyl (PVAc) adhesives were used as glue. Bearing in mind the critical loads that may affect their use, experimental samples were tested under diagonal loads. Experimental samples were also analyzed by a computer program using the finite element method (FEM). Finally, experimental data were compared with the results of FEM. The comparisons clearly showed that experimental results and finite element solutions (SAP2000 V17) including semi-rigid connections are in good agreement. As a structural analysis program in furniture engineering designs, FEM can be preferred in terms of reliability and cost. - U radu se prikazuju rezultati istraživanja uzoraka borovine (Pinus slyvestris L.), bukovine (Fagus orientalis L.) i hrastovine (Quercus petreae L.) spojenih kutnim zupčastim spojevima i ojačanih vlaknima. Kao ljepilo upotrijebljeno je epoksidno ljepilo Teknobont 200 i polivinilacetatno ljepilo (PVAc). Imajući na umu opterećenja koja se pojavljuju tijekom uporabe, eksperimentalni su uzorci ispitivani pri dijagonalnim opterećenjima. Uzorci su također analizirani računalnim programom primjenom metode konačnih elemenata (FEM). Eksperimentalni podatci i podatci dobiveni FEM analizom uspoređeni su te se jasno može vidjeti da se ti podatci za polukrute vezove podudaraju. Glede pouzdanosti i troškova, kao strukturnom programu analize u dizajniranju namještaja prednost se može dati FEM analizi.

Hygrothermal treatment of tepa (Laureliopsis philippiana Looser) fibers [Elektronička građa] : effects on chemical and physical properties = Hidrotermička obrada iverja drva tepe (Laureliopsis philippiana Looser) : utjecaj na kemijska i fizička svojstva / Rommel Crespo Gutiérrez, Marco Torres Uribe, Hernán Poblete Wilson. - Graf. prikazi.
Bibliografija: 69 jed. - Abstract ; Sažetak. - The present study consisted in determining the effects of a hygrothermal treatment on wood fibers from the Laureliopsis philippiana Looser species. The fibers were treated in autoclave at 150 °C for 90 minutes at a pressure of 430 kPa, which was generated during the evaporation process of the water in autoclave. Physical properties, color, and water retention capacity of hygrothermically treated and untreated fibers were analyzed. The chemical properties determined were the extractable amount in sodium hydroxide, toluene ethanol, hot and cold water, the cellulose, holocellulose and lignin contents, the pH value, the percentage of volatile and washable acids, and the buffer capacity. In hygrothermically treated fibers, a change of color was detected as well as a reduction in the water retention capacity and an increase in the percentage of extractable, cellulose, lignin and a decrease of holocellulose. Also an increase in acidity, amount of volatile and washable acids and buffer capacity were determined. Due to the chemical changes observed in the treated fibers, these would present advantages in the manufacture of fiberboards, facilitating the setting of the amino resins. - Cilj rada bio je utvrditi učinke hidrotermičke obrade na vlakna drva Laureliopsis philippiana Looser. Vlakna su tretirana u autoklavu, na temperaturi 150 °C tijekom 90 minuta, i pri tlaku 430 kPa, koji je nastao tijekom procesa isparavanja vode u autoklavu. Analizirana su fizička svojstva, boja i kapacitet zadržavanja vode u hidrotermički obrađenim i neobrađenim vlaknima. Od kemijskih svojstava određena je ekstrahirana količina u natrijevu hidroksidu, toluen-etanolu te u toploj i hladnoj vodi, zatim sadržaj celuloze, holoceluloze i lignina, pH vrijednost, postotak hlapljivih kiselina i kiselina koje se mogu isprati te kapacitet pufera. U hidrotermički tretiranim vlaknima zabilježena je promjena boje i smanjenje kapaciteta zadržavanja vode te povećanje postotka ekstrakta, sadržaja celuloze i lignina, kao i smanjenje sadržaja holoceluloze. Također je utvrđeno povećanje kiselosti, količine hlapljivih kiselina i kiselina koje se mogu isprati te određen kapacitet pufera. Zbog kemijskih promjena uočenih na obrađenim vlaknima takva bi vlakna mogla imati prednost u proizvodnji ploča vlaknatica jer olakšavaju pozicioniranje amino smola.

Improving weathering performance of wood by borates impregnation and liquid glass coating [Elektronička građa] = Poboljšanje otpornosti drva na vremenske utjecaje impregnacijom boratima i premazom od tekućeg stakla / Mustafa Kucuktuvek, Hilmi Toker, Turkay Turkoglu, Ahmet Gunduz, Caglar Altay, Ergun Baysal. - Graf. prikazi.
Bibliografija: 50 jed. - Abstract ; Sažetak. - Weathering performance of impregnated and coated wood products is an important issue that influences their appearance as well as their service life after outdoor or indoor exposure. A novel procedure to improve the weathering performance of Scots pine wood (Pinus sylvestris L.) is proposed in this study. Wood samples were impregnated with ammonium tetrafluoroborate (ATFB), ammonium pentaborate (APB) and boric acid (BA), and afterward coated with a layer of liquid glass (LG). Surface hardness, color changes, and surface roughness of wood samples were investigated after 250 h and 500 h of exposure to artificial weathering. The results revealed that, except for untreated (control), all other treatment groups caused an increase in surface hardness of Scots pine after weathering. A decrease in the CIE L* value corresponds to the darkening of samples after weathering. Borates-impregnated and LG-coated Scots pine samples possessed the highest color stability. However, all treatment combinations resulted in reddish and yellowish tones after weathering. Exposure to weathering increased surface roughness of wood samples. The surface roughness of the untreated (control) group was higher than that of impregnated and coated samples. - Otpornost impregniranoga i premazanog drva pri izlaganju vremenskim utjecajima velik je problem koji utječe na izgled i vijek trajanja drva nakon izlaganja u eksterijeru ili interijeru. U ovom je istraživanju predložen novi postupak poboljšanja otpornosti borovine (Pinus sylvestris L.) izložene vremenskim utjecajima. Uzorci drva impregnirani su amonijevim tetrafl uoroboratom (ATFB), amonijevim pentaboratom (APB) i bornom kiselinom (BA), nakon čega su premazani tekućim staklom (LG). Ispitivana je tvrdoća površine, promjena boje i hrapavost površine uzoraka drva nakon 250 i 500 sati umjetnog izlaganja vremenskim utjecajima. Rezultati su pokazali da se na svim površinski obrađenim uzorcima borovine povećala tvrdoća njezine površine nakon izlaganja vremenskim utjecajima. Smanjenje vrijednosti CIE L* upućuje na tamnjenje uzoraka nakon izlaganja vremenskim utjecajima. Najbolju stabilnost boje pokazali su uzorci borovine impregnirani boratima i premazani tekućim staklom. Međutim, sve kombinacije površinske obrade rezultirale su povećanjem crvenoga i žutog tona nakon izlaganja uzoraka vremenskim utjecajima. Izlaganjem vremenskim utjecajima povećala se hrapavost površine uzoraka drva. No hrapavost površine kontrolnih uzoraka (površinski neobrađenih) bila je veća nego hrapavost površine impregniranih i premazanih uzoraka.

Influence of fibre length on properties of glass-fibre reinforced bark particleboards [Elektronička građa] = Utjecaj duljine vlakana na svojstva iverice od kore ojačane staklenim vlaknima / Zoltan Pásztory, Zoltan Börcsök, Dimitrios Tsalagkas. - Ilustr.
Bibliografija: 29 jed. - Abstract ; Sažetak. - This study was carried out to assess the feasibility of glass fibres of various lengths (12 mm, 18 mm, 24 mm and 30 mm) as reinforcement on the mechanical performance of bark particleboards intended for thermal insulation. To evaluate their efficiency, the results of fibre reinforced particleboards at mass of 3wt% concentration were compared with plain bark based boards. Thermal, physical and mechanical properties (modulus of rupture, modulus of elasticity and internal bond) were determined on unreinforced and reinforced specimens. In general, the results of the thermal conductivity measurements indicated that the bark panels could potentially be used as feedstock for thermal insulation panels. However, the glass fibres lengths had a direct adverse effect on the mechanical behaviour of the bark particleboard, instead of providing synergistic reinforcement. Furthermore, the static bending properties, mainly the modulus of rupture, gradually decreased with increasing lengths of glass fibre. - Istraživanje je provedeno kako bi se procijenila mogućnost uporabe staklenih vlakana različitih duljina (12; 18; 24 i 30 mm) kao materijala za ojačanje iverica proizvedenih od kore i namijenjenih toplinskoj izolaciji te kako bi se istražio utjecaj tih vlakana na mehanička svojstva iverica. Da bi se procijenio utjecaj staklenih vlakana, uspoređena su svojstva iverica ojačanih staklenim vlaknima masenog udjela vlakana od 3 % i iverica napravljenih od kore, bez ojačanja staklenim vlaknima. Uspoređena su toplinska, fizička i mehanička svojstva (modul loma, modul elastičnosti i međuslojna čvrstoća) uzoraka ploča iverica s ojačanjem staklenim vlaknima i bez ojačanja. U osnovi, rezultati mjerenja toplinske vodljivosti pokazali su da bi se ploče od kore mogle potencijalno upotrebljavati za toplinsku izolaciju. Međutim, duljina staklenih vlakana imala je izravan nepovoljan utjecaj na mehanička svojstva iverica od kore. Nadalje, svojstva statičkog savijanja, uglavnom modul loma, postupno su se smanjivala s povećanjem duljine staklenih vlakana.

The influence of wood modification on transfer function of a violin bridge [Elektronička građa] = Utjecaj modifikacije drva na prijenosnu funkciju mosta za violinu / Miran Merhar, Miha Humar. - Ilustr.
Bibliografija: 22 jed. - Abstract ; Sažetak. - The violin bridge is an important component of a violin since it transmits the excitation forces from the string to the violin body. Depending on its structure, at a certain frequency spectrum, the bridge acts as a damper or amplifier of excitation forces, which depends on its transfer function. In the study, transfer functions in the range from 400 Hz to 7000 Hz in vertical directions of 3 bridges were measured. The bridges were made from maple wood and supplied by different manufacturers. The bridges were then thermally modified, and the transfer functions were measured again. To determine the influence of thermal modification on material properties, a sample of maple wood was also modified together with the bridges, and the modulus of elasticity and shear modulus before and after the modification were measured. Using Ansys software, a bridge was modelled by the finite element method, by which natural frequencies and transfer functions before and after the modification were calculated. It can be confirmed from the research that wood modification influences the bridge transfer function and that the finite element method can be used to determine the dynamic properties of the bridge by knowing the wood material properties and, therefore, to predetermine the transfer function of the violin bridge before its production. - Most na violini važan je dio toga glazbala jer prenosi pobudne sile iz žica u tijelo violine. Ovisno o svojoj strukturi, most na određenome frekvencijskom spektru djeluje kao prigušivač ili kao pojačalo pobudnih sila, što ovisi o njegovoj prijenosnoj funkciji. U istraživanju su mjerene prijenosne funkcije u rasponu od 400 do 7000 Hz u okomitim smjerovima na tri mosta. Mostove od javorova drva izradili su različitih proizvođači. Naknadno su mostovi toplinski modificirani i ponovo su izmjerene njihove funkcije prijenosa. Da bi se utvrdio utjecaj toplinske modifikacije na svojstva materijala, zajedno s mostovima modificiran je i uzorak javorova drva te su izmjereni modul elastičnosti i modul smicanja prije i nakon modifikacije. Uz upotrebu softvera Ansys most je modeliran metodom konačnih elemenata, kojom su izračunane prirodne frekvencije i funkcije prijenosa prije i nakon modifikacije. Na temelju istraživanja može se potvrditi da modifikacija drva utječe na funkciju prijenosa mosta i da se metodom konačnih elemenata mogu odrediti dinamička svojstva mosta ako su poznata svojstva drvnog materijala. Prema tome, prijenosna funkcija mosta violine može se odrediti unaprijed, prije njegove izrade.

Konfiskacija karlovačke tekstilne industrije (1945. - 1946.) [Elektronička građa] / Nikola Perković. - Graf. prikazi.
Bibliografske bilješke uz tekst ; bibliografija: 11 jed. - Sažetak ; Summary. - Autor na temelju arhivskoga gradiva i literature opisuje i objašnjava gospodarske procese na području Karlovca i njegove uže okolice uvjetovane političkim odlukama neposredno nakon Drugoga svjetskog rata 1945. i 1946. godine. - The topic of this paper are the economic processes initiated through political decisions in Karlovac and its surroundings after World War II, from 1945 to 1946. In a wider context of economic relations, the focus is on the confiscation of the textile industry in Karlovac and its surroundings as a leading initiator of economic development in the mentioned area. Confiscation, through judicial government, meant taking private property away by force with the aim of collectivising property for the needs of the central unitarist and totalitarian government. After studying the available documentation, it is obvious that the most successful companies in the textile industry, but not only them, became the state’s property via judicial decisions. After that, the state, through its administrative and central way of governing, made all important business decisions related to the confiscated companies as well as directly about the economic situation in the whole country. Moreover, it is important to emphasise that confiscation was one of the ways used to punish pre-war and wartime political opponents. It was also a way of making them unimportant in social relations, and finally making them dependent on the central government, which, as I have already stressed, dictated political and economic processes on all levels.

Laibach, anti-fashion and subversion [Elektronička građa] : over-identification and universality of a uniform / Tajda Hlačar. - Ilustr.
Bilješke uz tekst. - Bibliografija: 43 jed. - Summary. - The worldwide renowned Slovenian industrial alternative music group Laibach, which was also a member of the multimedia artists’ collective called NSK, has been a subject of many professional discussions. This article attempts to analyse Laibach’s conception of a uniform according to the theory of anti-fashion. As one of the most recognizable elements expressing a mythical, totalitarian aura, inseparably linked with the performers’ distant and constrained attitude, Laibach’s uniform can be erroneously comprehended as anti-fashion clothing, expressing fixed and rigid social environments. The analysis of Laibach’s television interview from 1983, in which the band is directly imitating the ruling ideological language, shows that the strategy of over-identification and subversion represent dominant principles of Laibach’s actions, combining them with the retro-method of using symbols and images of various cultural traditions and periods, as seen in their diversity of clothing worn, including the Yugoslav military uniform, miner and hunting uniforms, jeans and shirts, and even fashionable items. With the performative dimension in the ideological ritual and by emphasizing totalitarian tendencies in contemporary society, Laibach endeavours to show that all changeable multiform clothes are uniforms – timeless, universal and deprived of semiological meaning and thus surpasses the distinction of fashion and anti-fashion or fixed and modish costume. Nearly forty years after the establishment of the group, Laibach is conventionally dressed in regular clothes, nevertheless providing a sentiment of wearing a collective’s uniform.

Mechanical properties and free formaldehyde content of particleboards produced using ammonium sulphate-based hardener partially replaced with tartaric acid [Elektronička građa] = Mehanička svojstva i sadržaj slobodnog formaldehida ploča iverica izrađenih primjenom katalizatora na bazi amonijeva sulfata djelomično zamijenjenoga vinskom kiselinom / Nikola Španić, Vladimir Jambreković, Jaroslav Kljak, Goran Mihulja, Željko Milanović. - Graf. prikazi.
Bibliografija: 22 jed. - Abstract ; Sažetak. - The use of resins, whose curing reaction takes place by high temperature and hardener addition, is inevitably involved in particleboard manufacturing process. In addition to commercial hardeners, such as ammonium sulphate, with the aim of optimizing the production process and reducing the production costs, a certain percentage of hardener can, among other things, be replaced with price affordable bio-based materials. Tartaric acid, that is its salts (tartrates), which are commercially produced for the needs of wine and food industries, are a part of the aforementioned group of products. Since tartaric acid is a relatively inexpensive, readily available, weak diprotic and aldaric acid, the question arises whether it can be used as a component of the hardener system for curing urea-formaldehyde resins that are commercially used in particleboard production. For that reason, in this paper, the influence of partial replacement of ammonium sulphate hardener with tartaric acid on the mechanical properties (bending strength, modulus of elasticity and internal bond) and free formaldehyde content of experimentally produced particleboards was examined. Boards thickness, density and moisture content were also determined. The test results suggest that tartaric acid has a beneficial effect on the above particleboard properties, but they also indicate that the extent of that effect is strongly dependent on panel press time. - Proces proizvodnje ploča iverica neminovno podrazumijeva upotrebu smola čija se reakcija otvrdnjavanja ostvaruje uz pomoć povišene temperature i katalizatora. Uz komercijalne katalizatore poput amonijeva sulfata, radi optimizacije procesa i racionalizacije troškova proizvodnje ploča, katalizatore je u određenom postotku moguće zamijeniti, među ostalim, i cijenom prihvatljivim proizvodima na biobazi. U navedenu se skupinu proizvoda svrstava i vinska kiselina, točnije njezine soli (tartarati), komercijalno proizvedene za potrebe vinske i prehrambene industrije. S obzirom na to da je vinska kiselina relativno jeftina, lako dostupna, slaba diprotonska, aldarna kiselina, postavlja se pitanje potencijala njezine primjene u sustavima katalizatora za otvrdnjavanje ureaformaldehidne smole koja se upotrebljava u proizvodnji ploča iverica. Upravo je zato u ovom radu ispitano kako se zamjena dijela amonijeva sulfata tartaratnom kiselinom odražava na mehanička svojstva (savojnu čvrstoću, modul elastičnosti, vlačnu čvrstoću) i na koncentraciju slobodnog formaldehida eksperimentalno proizvedenih ploča iverica. Usto, u eksperimentu su određene debljina i gustoća ploča te sadržaj vode u njima. Rezultati ispitivanja upućuju na to da dodatak vinske kiseline povoljno utječe na navedena svojstva ploča, ali i na činjenicu kako taj učinak iznimno ovisi o vremenu prešanja ploča.

Modelling and simulation of compression behaviour of 3D woven hollow composite structures using FEM analysis [Elektronička građa] / Lekhani Tripathi, Soumya Chowdhury, Bijoya Kumar Behera. - Ilustr., graf. prikazi.
Bibliografija: 34 jed. - Summary. - Three-dimensional (3D) woven spacer composites have the advantage of being lightweight and strong for use in various segments of structural engineering and automobiles due to their superior mechanical properties than conventional counterparts. In this investigation, the influence of different cell geometries of 3D woven spacer fabrics, namely rectangular, triangular and trapezoidal with woven cross-links, upon their mechanical behaviors, especially compression energy, was studied through FEM (finite element method). Cell geometries were changed into different heights and widths and evaluated through simulation and experiments. Simulation of the structure was carried out by the Abaqus platform, and validation of the results was done for the rectangular structure. It was found that compression energy increases with an increment in width, while initially, it shows the tendency to increase and subsequently decrease with an increment in height for the rectangular structure. Compression energy increases with an increase in the angle of the triangular structure; however, it shows the opposite trend in the case of the trapezoidal structure. The outcome of the result shows good agreement between simulation and experimentation values of more than 94% accuracy.

Numerical modelling of stiffness of RTA furniture with new externally invisible and dismountable joints [Elektronička građa] = Numeričko modeliranje krutosti RTA namještaja s novim, izvana nevidljivim vezovima / Łukasz Krzyżaniak, Jerzy Smardzewski, Silvana Prekrat. - Ilustr. ; graf. prikazi.
Bibliografija: 17 jed. - Abstract ; Sažetak. - The distribution of furniture sold in the form of flat packages requires the use of appropriate design solutions. These include joints, which need to facilitate self-assembly with no need to use tools. Such joints should be functional, aesthetically attractive, durable and safe to use. It was decided in this study to manufacture prototypes of innovative furniture joints and evaluate the quality of furniture assembled using these joints. For this purpose, the finite element method and the Abaqus program were used. Joints were modelled as objects made of polylactide (PLA). Surface to surface contact and assembly forces resulting from the construction of joints were introduced between the elements of the joint. The furniture case was subjected to torsional loads. The rigidity of furniture and stress distribution in joints were calculated. On the basis of numerical calculations, the joints were positively validated. - Prodaja namještaja koji se isporučuje u obliku ravnih paketa zahtijeva primjenu odgovarajućih dizajnerskih rješenja.

Za ovo su istraživanje autori odlučili proizvesti prototipove inovativnih vezova namještaja te procijeniti kvalitetu namještaja sastavljenoga uz pomoć takvih vezova. Za tu je namjenu primijenjena metoda konačnih elemenata i program Abaqus. Vezovi su modelirani kao predmeti izrađeni od polilaktida (PLA). Između elemenata veza djeluju površinske i kontaktne sile koje nastaju konstrukcijom vezova. Korpus namještaja bio je podvrgnut torzijskim opterećenjima. Izračunana je krutost namještaja i raspodjela naprezanja u vezovima. Na temelju brojčanih izračuna vezovi su pozitivno ocijenjeni.

On-line measurement of wood surface smoothness [Elektronička građa] = Online mjerenje glatkoće površine drva / Jakub Sandak, Kazimierz A. Orlowski, Anna Sandak, Daniel Chuchala, Piotr Taube. - Ilustr.
Bibliografija: 20 jed. - Abstract ; Sažetak. - The latest progress in the field of optics and microelectronics resulted in the development of new generation vision systems capable of scanning surface topography with very high sampling frequencies. The blue color of illuminating light as well as novel systems for controlling ultra-thin laser line thickness allows the measurement of the porous surface of wood with a triangulation method. Three alternative sensors were tested here in order to verify their suitability for the determination of surface topography in the industrial environment. The scanning head was installed at the exit zone of the four-side profiling moulder and was set to scrutinize the wood surface shape line-by-line, immediately after profiling. The sensor was also tested for automatic detection of surface defects appearing on the elements after sanding, wetting and painting with various finishing products. The set of pilot test results is presented, together with an original algorithm for real-time surface defects detection. - Najnoviji napredak u području optike i mikroelektronike rezultirao je novom generacijom skenera koji mogu skenirati topografiju površine vrlo visokom frekvencijom uzorkovanja. Svjetlost plave boje, kao i novi sustav za kontrolu vrlo tanke laserske zrake omogućuju mjerenje porozne površine drva metodom triangulacije. Testirana su tri alternativna senzora kako bi se potvrdila njihova prikladnost za određivanje topografije površine u industrijskim uvjetima. Glava za skeniranje postavljena je na izlazu četverostranoga profilnoga glodala kako bi se odmah nakon profiliranja pomno linijski skenirala površina drva. Senzor je također testiran za automatsko otkrivanje površinskih grešaka na elementima nakon brušenja, vlaženja i premazivanja različitim premaznim materijalima. Predstavljen je set rezultata pilot-ispitivanja, zajedno s originalnim algoritmom za otkrivanje površinskih grešaka u realnom vremenu.

Optimal surface preparation for wood anatomy research of invasive species by scanning electron microscopy [Elektronička građa] = Optimalna priprema površine drva za istraživanje anatomije invazivnih vrsta drva pretražnim elektronskim mikroskopom / Maks Merela, Nejc Thaler, Angela Balzano, Denis Plavčak. - Ilustr.
Bibliografija: 47 jed. - Abstract ; Sažetak. - Research was done to develop the optimal method of wood surface preparation for scanning electron microscopy (SEM). Since 2018, environmental scanning electron microscope (ESEM™) FEI Quanta 250 has been installed at the Department of Wood Science and Technology in Ljubljana. We tested several methods for the pre-preparation and cutting of wood surfaces for SEM analyses. The samples had been either dried, soaked in water and frozen, impregnated with paraffin or simply moistened before cutting. We analysed wood surfaces obtained by splitting, sawing, planing, sanding and cutting on a sliding microtome with different blades. The effect of gold coating on the SEM image quality was also evaluated. Best results were obtained by cutting a pre-moistened surface on a sliding microtome with a low profile replaceable blade and gold coated afterwards. Determined methodology is technically less demanding, not time consuming and obtains results that satisfy needs for wood anatomy research at magnifications up to 12.000x. Guidelines for the optimal preparation of samples were prepared, and theoretical and practical basis for investigations of wood anatomy using SEM were provided. The method was afterwards used in analyses of invasive alien plant species – investigating their anatomical structure in the framework of the AlienPLAntSpEcies - APPLAUSE project (Urban Innovative Actions initiative). It was demonstrated that the use of the SEM opened new scope in detailed investigations of the wood structure and properties. - Istraživanje je provedeno kako bi se razvila optimalna metoda pripreme drvne površine za pretražnu elektronsku mikroskopiju (SEM). Od 2018. na Odsjeku za znanost i tehnologiju o drvu u Ljubljani instaliran je uređaj za pretražnu elektronsku mikroskopiju u uvjetima okoliša (ESEMTM) FEI Quanta 250. Proučavali smo nekoliko metoda za pripremu i rezanje površine drva za SEM analizu. Uzorci su sušeni, potapani u vodi i smrzavani te prije rezanja impregnirani parafi nom ili samo navlaženi. Analizirali smo površine drva dobivene cijepanjem, piljenjem, blanjanjem, brušenjem i rezanjem na mikrotomu različitim oštricama. Također je proučavan utjecaj zlatnog premaza na kvalitetu SEM fotografi ja. Najbolji rezultati dobiveni su rezanjem prethodno navlažene površine na mikrotomu, i to zamjenjivim noževima niskog profi la, nakon čega je površina drva pozlaćena. Primijenjena je metodologija tehnički manje zahtjevna, ne oduzima mnogo vremena, a dobiveni rezultati zadovoljavaju potrebe istraživanja anatomije drva pri povećanju i do 12 000 puta. Sastavljene su smjernice za optimalnu pripremu uzoraka te je postavljena teorijska i praktična osnova za istraživanje anatomije drva primjenom SEM-a. Metoda je potom primijenjena za istraživanje invazivnih biljnih vrsta – za ispitivanje njihove anatomske strukture u sklopu projekta AlienPLAntSpEcies – APPLAUSE (Urban Innovative Actions). Potvrđeno je da je upotreba SEM-a otvorila novo područje u detaljnim istraživanjima strukture i svojstava drva.

Physical properties of juvenile wood of two paulownia hybrids [Elektronička građa] = Fizička svojstva juvenilnog drva dvaju hibrida paulovnije / Tomislav Sedlar, Bogoslav Šefc, Damir Drvodelić, Branimir Jambreković, Marko Kučinić, Iva Ištok. - Graf. prikazi.
Bibliografija: 25 jed. - Abstract ; Sažetak. - There is a growing trend in the world of planting fast growing species (rotations 5 to 10 years). Their primary purpose is the production of wood fibers and biomass, but they certainly represent the potential in making solid wood products as well. One of the fast-growing species is Paulownia sp., a species of extremely fast growing wood. Plantation breeding of Paulownia sp. in Croatia is increasing, although there is a little knowledge about the technical properties of Paulownia wood and its end use is questionable. This paper presents preliminary results of some physical properties of juvenile wood of two Paulownia hybrids planted in the area near the town of Glina in the Republic of Croatia. One hybrid is 9501 ((Paulownia fortunei × Paulownia elongata) × (Paulownia fortunei × Paulownia tomentosa)) and the other hybrid is Shan Tong (Paulownia fortunei × Paulownia tomentosa). The aim of this study was to investigate physical properties of juvenile wood of two Paulownia hybrids from one site in Croatia, to determine differences in physical properties of wood between two hybrids and to evaluate the correlation between density and shrinkages of each hybrid. Significant differences in oven dry density, basic density and density at maximum MC, between the two hybrids were determined. There is no statistically significant difference in longitudinal, radial, tangential and volumetric shrinkages between the two hybrids. - U današnje je vrijeme zamjetan sve češći trend sadnje brzorastućih vrsta drveća (ophodnje od 5 do 10 godina). Te su vrste primarno namijenjene proizvodnji drvnih vlakana i biomase, ali svakako je vidljiv i njihov potencijal u proizvodima od cjelovitog drva. Jedna od brzorastućih vrsta je Paulownia sp., koju odlikuje izrazito brz rast. Iako se malo zna o tehničkim svojstvima drva paulovnije, a njegova je krajnja upotreba upitna, u Hrvatskoj je u porastu plantažni uzgoj paulovnije. U ovom su radu prikazani preliminarni rezultati istraživanja nekih fizičkih svojstava juvenilnog drva hibrida paulovnije s lokaliteta u blizini grada Gline u Hrvatskoj. Prvi je hibrid 9501 ((Paulownia fortunei × Paulownia elongata) × (Paulownia fortunei × Paulownia tomentosa)), a drugi Shan Tong (Paulownia fortunei × Paulownia tomentosa). Cilj rada bio je istražiti fizička svojstva juvenilnog drva hibrida paulovnije s lokaliteta u Hrvatskoj, utvrditi razlike u fizičkim svojstvima drva tih hibrida te odrediti međusobni odnos gustoće i utezanja unutar hibrida. Utvrđene su značajne razlike u gustoći drva u apsolutno suhom stanju, u nominalnoj gustoći i gustoći pri maksimalnom sadržaju vode između tih dvaju hibrida. Među hibridima nisu utvrđene statistički značajne razlike u longitudinalnome, radijalnome, tangentnome ni volumnom utezanju.

Pine wood particles pyrolysis and radiographic analysis [Elektronička građa] = Piroliza čestica borovine i radiološka analiza / Paweł Kazimierski, Sara Vieira, Dariusz Kardaś. - Ilustr.
Bibliografija: 9 jed. - Abstract ; Sažetak. - The goal of this experiment is to assess the mass and volume loss of medium size pine wood particles undergoing pyrolysis. Wood samples of different sizes and shapes were pyrolysed at 500 ºC with different residence times. A thermogravimetric analysis was carried out for comparison purposes. Finally, the pyrolysed samples were analysed using radiographic methods. A connection between the different analyses was found. For larger particles, the heating rate is lower, and a time gap between hemicellulose and cellulose thermal decomposition was noticed. Research shows that an important part of the analysis of the process is the rate of biomass heating and sample size. As the sample size increases, the pyrolysis time increases; however, the increase is not linear. The publication also shows the great possibilities of radiographic methods in analysing the pyrolysis process. - Cilj istraživanja bio je procijeniti gubitak mase i volumena čestica borovine srednje veličine podvrgnutih pirolizi. Uzorci drva različitih veličina i oblika pirolizirani su pri 500 °C i pri različitim vremenima trajanja pirolize. Za usporedbu je provedena termogravimetrijska analiza borovih čestica. Nakon toga pirolizirani su uzorci analizirani metodom radiografije. Pronađena je veza između različitih analiza. Brzina zagrijavanja većih čestica je niža, a primijećen je i vremenski jaz između toplinskog raspadanja hemiceluloze i celuloze. Istraživanja su pokazala da su važan dio analize procesa pirolize brzina zagrijavanja biomase i veličina uzorka. Kako se veličina uzorka povećava, tako se povećava i vrijeme pirolize, i to nelinearno. Usto, rad upućuje na velike mogućnosti radiografskih metoda u analizi procesa pirolize.

Possibilities of increasing renewable energy in Croatia, Slovenia and Slovakia - wood pellets [Elektronička građa] = Mogućnosti povećanja obnovljivih izvora energije u Hrvatskoj, Sloveniji i Slovačkoj - drvni peleti / Andreja Pirc Barčić, Petra Grošelj, Leon Oblak, Darko Motik, Vladislav Kaputa, Branko Glavonjić, Margarita Bego, Ivana Perić. - Graf. prikazi.
Bibliografija: 32 jed. - Abstract ; Sažetak. - Energy from renewable sources is globally a very important issue. In order to reduce pollution and greenhouse gas emissions, many countries enact laws for enhancing the consumption of renewable energy sources. Sooner or later traditional non-renewable energy sources would have to be replaced with alternative energy sources that are already used in developed countries. According to the European Commission (2018), the EU is already a global leader in the sustainable use of natural resources within an efficient bio-economy. The wood pellet industry is becoming more important and the use of wood pellets is increasing as one of the most important contributors to the renewable energy goals of the EU. Wood pellet is an environmentally acceptable product and its production contributes to desirable rural development and sustainable approach to the management of timber resources. This paper focuses on the market of wood pellets used for heating, pinpointing differences in consumers point of view, and drafting the possibilities of future consumption enhancement. Results revealed a relatively low use of wood pellets in all the three surveyed markets. The highest share of consumers of wood pellets came from the areas with less than 5,000 inhabitants. Such households were mostly over 20 years old. The most important factors to decide to use such source of energy were space (required for the heating system) followed by price of wooden pellets. - Energija iz obnovljivih izvora globalno je vrlo važno pitanje. Radi smanjenja onečišćenja i emisiji stakleničkih plinova, države promiču zakone o poticanju potrošnje obnovljivih izvora energije. Prije ili kasnije tradicionalne neobnovljive izvore energije bit će potrebno zamijeniti alternativnima, koji se već koriste u razvijenim zemljama. Prema Europskoj komisiji, Europska unija (EU) lider je u održivom iskorištavanju prirodnih resursa u sklopu učinkovite bioekonomije. U tom kontekstu industrija drvnih peleta, kao i njihova upotreba, iz dana u dan postaju sve nezaobilazniji. U dijelu koji se odnosi na obnovljive izvore energije drvni su peleti jedan od važnijih elemenata koji pridonose ciljevima EU-a. Riječ je o ekološki prihvatljivom proizvodu, a njegova proizvodnja znatno pridonosi ruralnom razvoju i održivom pristupu gospodarenju prirodnim resursima. Ovim se radom želi potaknuti promišljanje kako proizvođača, tako i potrošača drvnih peleta o izrazitom tržišnom potencijalu drvnog peleta za grijanje u hrvatskim, slovenskim i slovačkim kućanstvima. Nadalje, u radu su prikazane razlike u demografskim profilima ispitanika, njihovo znanje o drvenim peletima općenito te o mogućnostima budućeg poticanja potrošnje drvnih peleta u Hrvatskoj, Sloveniji i Slovačkoj. Rezultati su pokazali da je uporaba peleta na sva tri istraživana tržišta relativno niska. Najveći udio potrošnje peleta zabilježen je među potrošačima iz manjih područja (do 5000 stanovnika), a većina stambenih objekata ispitanika stariji su od 20 godina. Najvažniji razlozi zbog kojih se potrošači odlučuju na upotrebu peleta kao izvora grijanja jest prostor potreban za instalaciju opreme za grijanje na pelete te cijena peleta.

Preferences of different target groups of consumers in case of furniture purchase [Elektronička građa] = Sklonosti kupaca pri donošenju odluke o kupnji namještaja / Leon Oblak, Branko Glavonjić, Andreja Pirc Barčić, Teja Bizjak Govedič, Petra Grošelj. - Graf. prikazi.
Bibliografija: 29 jed. - Abstract ; Sažetak. - In a market environment where changes are constant, understanding customer buying behaviour is crucial for companies in order to operate both successfully and effectively. We analysed how different age groups and net monthly incomes per household influence consumer decisions in Slovenia, Serbia and Croatia in the case of furniture purchases, when the three main factors are material, price and service. Each factor was further divided into three levels. In the case of material, the respondents could choose between solid wood, chipboard and fibreboard or other materials. In the case of price, they could choose between a low, middle or high price range, and in the case of services, they could choose between pre-sales, sales and after-sales services. With conjoint analysis, we analysed the markets in Slovenia, Serbia and Croatia. The important differences in consumer buying behaviour in these three countries were discovered. The results of the research will serve as a useful basis for wood sector companies to design more successful marketing strategies, which will help them to achieve their goals in different target markets. - Razumijevanje ponašanja kupaca u današnjemu, vrlo promjenjivom tržišnom okruženju jedan je od odlučujućih elemenata za postizanje uspješnoga i učinkovitoga poslovnog rezultata tvrtke. Osnovni je cilj ovog istraživanja bio utvrditi kako u Sloveniji, Srbiji i Hrvatskoj različita dob potrošača te mjesečni neto prihod njihova kućanstva utječu na donošenje odluke o kupnji namještaja, i to promatrajući tri osnovna faktora proizvoda – materijal od kojega je izrađen, cijenu i uslugu. Nadalje, za svaki faktor proizvoda bile su ponuđene tri mogućnosti odabira. Tako su za faktor materijal izrade proizvoda ispitanici mogli odabrati između masivnog drva i ploča iverica ili ploča vlaknatica te drugih materijala; glede faktora cijena proizvoda ispitanici su se mogli odlučiti za niski, srednji ili visoki cjenovni razred proizvoda, dok su za faktor usluga mogli odabrati između pretprodajne, prodajne i postprodajne usluge. Rezultati su pokazali kako pri kupnji namještaja među promatranim grupama ispitanika postoje razlike u donošenju odluke, i to u sve tri promatrane zemlje. Rezultati provedenog istraživanja moći će poslužiti tvrtkama drvnoindustrijskog sektora za osmišljavanje i izgradnju uspješnih marketinških strategija.

Properties of plywood produced with urea-formaldehyde adhesive modified with nanocellulose and microcellulose [Elektronička građa] = Svojstva furnirskih ploča proizvedenih s ureaformaldehidnim adhezivom modificiranim nanocelulozom i mikrocelulozom / Jakub Kawalerczyk, Dorota Dziurka, Radosław Mirski, Kinga Szentner. - Graf. prikazi.
Bibliografija: 40 jed. - Abstract ; Sažetak. - Urea-formaldehyde adhesives are widely used in the wood-based materials industry. The study investigates the possibility of using cellulosic particles as a filler that modifies the properties of the resin and consequently improves the properties of plywood. Moreover, the study also examines the differences between microcellulose and nanocellulose used as a filler for UF adhesive. Based on the investigations, it was found that the addition of MFC and NCC significantly affected the curing process and rheological behaviour of adhesive mixtures. Modification led to increase of viscosity and extension of a gel time caused by lowering solid content of the resin. The experimental and reference plywood were tested in terms of bonding quality and mechanical properties such as modulus of elasticity and modulus of rigidity in accordance with applicable standards. The results of the tests confirmed that both the amount and the type of modifier added to the resin had a significant effect on the properties of plywood. The bonding quality and the above mentioned mechanical properties improved in all variants of modification; however the most effective was the addition of NCC in the amount of 10 %/100 g of solid resin. The slight decrease of formaldehyde emission was only observed for 5 % cellulosic particles added to 100 g of solid UF. - Urea-formaldehidni (UF) adhezivi imaju široku primjenu u industriji materijala na bazi drva. U radu je opisano istraživanje mogućnosti upotrebe celuloznih čestica kao punila koje mijenja svojstva smole i posljedično poboljšava svojstva furnirske ploče. Nadalje, u istraživanju su ispitane razlike između mikroceluloze (MFC) i nanoceluloze (NCC) koje su upotrijebljene kao punilo za adheziv na bazi UF adheziva. Na temelju ispitivanja utvrđeno je da MFC i NCC dodatci znatno utječu na postupak stvrdnjavanja i reološko ponašanje adhezivnih smjesa. Modifikacija je rezultirala povećanjem viskoznosti i produljenjem vremena geliranja uzrokovanoga smanjenjem sadržaja čvrste smole. Ispitani su kvaliteta vezanja i mehanička svojstva eksperimentalne i referentne furnirske ploče poput modula elastičnosti i modula krutosti, sukladno odgovarajućim normama. Rezultati ispitivanja potvrdili su da i količina i vrsta modifikatora dodanoga u smolu imaju znatan utjecaj na svojstva furnirske ploče. Kvaliteta vezanja i spomenuta mehanička svojstva poboljšana su pri svim varijantama modifikacija, no najučinkovitije je bilo dodavanje NCC-a u količini od 10 % na 100 g čvrste smole. Blago smanjenje emisije formaldehida uočeno je samo za 5 % celuloznih čestica dodanih u 100 g čvrstog UF adheziva.

Removal of chromium(III) and other physical parameters from chrome tan wastewater and recovery of chromium from the precipitating sludge [Elektronička građa] / Md. Minhaz Uddin, Jawad Hasan, Md. Didarul Islam, Ashiqur Rahaman, Sayed Md. Shamsuddin. - Graf. prikazi.
Bibliografija: 46 jed. - Summary. - This study was adopted to investigate the removal of Cr(III)and other physicochemical parameters of chrome tan wastewater. For this purpose, three precipitating agents, CaCO3, NaHCO3, and MgO, were used to treat chrome tan wastewater. After treatment, it was found, in three different dose trials, that each agent removed almost 97-99.5 % of chromium. At the same time, it was observed that with the increase of doses, removal percentage of TDS, conductivity, and turbidity of effluent were reduced. In the case of NaHCO3 and CaCO3, Cr(III) removal percentage at optimum pH was found to be 99.97% and 99.95% respectively, whereas the maximum removal percentage for MgO was found to be 99.98%. The NaHCO3 and CaCO3 were found to be comparable to MgO for Cr(III) removal from chrome tan wastewater. The recovered chromium concentration in the sludge for NaHCO3 and CaCO3 were also similar to that of MgO. This research suggests that these two precipitating agents can be used in the same way as MgO, for Cr removal and recovery treatments. Moreover, this recovered chromium can be reused, thus reducing the environmental pollution.

School furniture ergonomics in prevention of pupils’ poor sitting posture [Elektronička građa] = Ergonomija školskog namještaja u prevenciji lošeg držanja tijela učenika / Aldina Alibegović, Amra Mačak Hadžiomerović, Adisa Pašalić, Danijela Domljan. - Graf. prikazi.
Bibliografija: 66 jed. - Abstract ; Sažetak. - Physical and psychological disorders in school-age children, as a consequence of prolonged sitting in class, denote one of the alarming issues of the today’s civilization. Scientific and professional literature pays great attention to the causes and phenomena of postural disorders caused by prolonged sitting, such as musculoskeletal disorders and back pain (MSD/BP). This phenomenon in children is increasingly correlated with school furniture design. School furniture, especially the chair and desk, are one of the most important factors to achieve the right body posture of pupils during school education. Despite this, not much attention is paid to the ergonomic requirements in furniture design, which are a prerequisite for good health, motivation improvement and learning of students. The objective of this paper is to show the impact of unmatched school furniture on the development of health problems and poor pupils’ posture through a review of scientific literature and previous studies concerning the issue. The results include a comparison of ten papers published in the period from 2004 to 2017 in Finland, Greece, Croatia, Slovenia, Nigeria, Brazil, Iran, Belgium, United Kingdom and India. Various databases have been used, including Pub Med, Google Scholar, Medline, Hrčak, Dabar, Science Direct and Science Citation Index. By reviewing the previous research of the selected authors dealing with sitting posture in school, an insight was gained into the effect of inadequate body postures on pupils’ health that could be used as guidance for new school furniture design. - Tjelesni i psihički poremećaji koji se pojavljuju u djece školske dobi kao posljedica dugotrajnog sjedenja na nastavi jedan su od alarmantnih problema današnje civilizacije. Znanstvena i stručna literatura veliku pozornost pridaju uzrocima i pojavama poremećaja držanja tijekom sjedenja, poput mišićno-koštanih smetnji i bolova u leđima (engl. MSD/BP). Ta se pojava u učenika sve više povezuje i s oblikovanjem školskog namještaja. Ergonomski oblikovan školski namještaj, poglavito stolice i stolovi, jedan su od važnih preduvjeta ispravnog držanja tijela učenika tijekom školske nastave. Usprkos tome, pri oblikovanju namještaja nedovoljno se uzimaju u obzir ergonomski zahtjevi kao uvjet dobrog zdravlja i unapređenja učeničke motivacije i uspješnog učenja. Cilj rada jest pokazati utjecaj neodgovarajućega školskog namještaja na pojavu zdravstvenih tegoba i lošeg držanja učenika, i to na temelju pregleda znanstvene literature i dosadašnjih istraživanja te problematike. Rezultati obuhvaćaju usporedbu deset objavljenih članaka u razdoblju 2004. – 2017., a ta su istraživanja provedena u Finskoj, Grčkoj,Republici Hrvatskoj, Sloveniji, Nigeriji, Brazilu, Iranu, Belgiji, Velikoj Britaniji i Indiji. Korištene su različite baze podataka, uključujući Pub Med, Google znalac, Medline, Hrčak, Dabar, Science Direct i Science Citation Index. Proučavanjem dosadašnjih istraživanja izdvojenih autora koji su se bavili problematikom sjedenja u školi dobiven je uvid o utjecaju neodgovarajućeg položaja tijela na zdravlje učenika, što može poslužiti kao smjernica u oblikovanju novoga školskog namještaja.

Bibliografija: 13 jed. - Abstract ; Sažetak. - Comparative analysis of the strength characteristics of one-seat upholstered furniture frame with rails of Pinus Sylvestris L. and side plates of PB, OSB and PLY boards was carried out. 3D geometric model of the upholstered furniture frame was created by Autodesk Inventor Pro®. Linear static analyses were carried out by the method of finite elements (FEM) simulating light-service loading. The orthotropic material characteristics of the used materials were considered in the analyses. Two variants of corner joints in the frame (model A – staples and PVAc; model B - staples, PVAc and strengthening elements under the rail of the seat) were considered. The laboratory established coefficients of rotational stiffness of used staple corner joints in the skeleton were considered in finite element analysis (FEA). As result, the distribution of the maximum and minimum principal stresses in the 3D model of upholstered furniture frame side plates were derived and analysed. The worst failure indexes according to Tsai-Wu failure criteria were calculated at heavy-service load. The study provided database of strength values that can help in the engineering of upholstered furniture frames with side plates of PB, OSB and PLY. - Provedena je usporedba svojstava čvrstoće okvira ojastučenog naslonjača s poveznicima od borovine (Pinus Sylvestris L.) i s bočnim stranicama od drvnih ploča (iverice, OSB ploče i furnirske ploče). Za potrebe ispitivanja uz pomoć programa Autodesk Inventor Pro® izrađen je 3D geometrijski model okvira ojastučenog namještaja. Linearne statičke analize provedene su metodom konačnih elemenata (FEM) uz simuliranje malog opterećenja. U analizama su uzeta u obzir svojstva ortotropnog materijala. Promatrane su dvije varijante kutnih spojeva okvira (model A – sponke i PVAc; model B – sponke, PVAc i pojačanja poveznika ispod sjedala). Analizom konačnih elemenata (FEA) razmatrani su laboratorijski utvrđeni koefi cijenti rotacijske krutosti sponki upotrijebljenih za kutne spojeve okvira. Time je dobivena i analizirana raspodjela najvećih i najmanjih glavnih naprezanja u 3D modelu bočnih stranica potkonstrukcije ojastučenog namještaja. Najlošiji indeksi loma prema Tsai-Wu kriterijima loma izračunani su pri velikim opterećenjima. Kao rezultat istraživanja dobivena je baza podataka o vrijednostima čvrstoće koja može pomoći u projektiranju okvira ojastučenog namještaja s bočnim stranicama od iverica, OSB ploča i furnirskih ploča.

Study on comparative analysis of basic woven fabrics produced in air-jet loom and determining structure for optimum mechanical properties and production [Elektronička građa] / Md. Nurunnabi, Jubayer Ibn Haris, Fairooz Raisa Mridula. - Graf. prikazi.
Bibliografija: 17 jed. - Summary. - This analysis was directed at dissecting the impact of the structure of the fabric on different properties of the fabric, for example tear strength, tensile strength, shrinkage, elongation, skewness, and so on. The work demonstrated how various structures of the fabric influence these properties. Fabrics with a fundamental woven structure, namely plain, twill, satin and a couple of their subsidiaries, were produced to explore the influence of the structure on different properties of the fabric. The examination built up an approach to gauge the mechanical conduct of the fabric dependent on its structure. The exploration accentuated the structure and detail of the fabric to decide the underlying driver of the change in the mechanical conduct. The properties of the fabric, such as tear strength, tensile strength, elongation, shrinkage and skewness, were extraordinarily affected by the structure of the fabric. It likewise demonstrated to having more noteworthy mechanical properties for firmly interwoven structures, such as plain and twill. The analysis led to the conclusion that the plain structure has the best mechanical properties among different structures.

Sustainable solid waste management in leather and textile industry [Elektronička građa] : leather & textile waste fibre-polymer composite and nanocomposite : overview and review / Venkatasubramanian Sivakumar, Resmi Mohan. - Ilustr., graf. prikazi.
Bibliografija: 50 jed. - Summary. - Proper disposal methods and solid waste management are necessary for all the processing industries such as leather, textile and chemical industry. In this regard, the present paper reviews in detail about the leather and textile waste fibre-polymer composites and nanocomposites as a viable solid waste management strategy. In the paper, several published papers and patents available in this area are reviewed in detail. This approach adopts confinement of leather or textile waste fibres in a polymer matrix as a composite. Nanocomposites of leather waste fibre and polymer with nano-particle reinforcement have been reported to have enhanced physical and other properties. This would not only solve the problem of the disposal issue regarding leather solid wastes containing leather or textile waste fibres, but also provide versatile composite or nanocomposite materials as “Wealth from Waste Approach”. The unique feature of the present analysis and the review paper is that both leather and textile waste management have been covered in the present approach for the first time.

Synthesis and application of graphene oxide (GO) for removal of cationic dyes from tannery effluents [Elektronička građa] / Md. Israil Hossain,, Amal Kanti Deb, Md. Rayhan Sarker, A. A. Shaikh, Manjushree Chowdhury,, Md. Zakir Sultan. - Ilustr., graf. prikazi.
Bibliografija: 29 jed. - Summary. - The increasing demands for dye in tanning industries have resulted in unconstrained throwing away of dyes into water bodies causing enormous environmental pollution. The removal of these dyes from effluents is mandatory and needs the recommendation of the latest technology and less expensive processes in this regard. Graphene oxide (GO) was prepared, characterized, and applied in the process of removal of cationic dye. GO was characterized by FTIR, X-RD, SEM, and TGA and the following functional groups were found: –COOH, OH, -C=O, and C-O-C. Basic Blue 3 (BB 3) was used as a model synthetic cationic dye. The dye adsorption studies were carried out in terms of the adsorbent dose, the pH, initial dye concentrations, and contact time. The removal efficiency for BB 3 was found to be 100% dye concentration up to 600 ppm at pH 7 with 10 mg (0.1g/L) of the adsorbent, GO, within 6 minutes. In the case of real tannery effluents, the eradication efficiency was found to be 91.2%. The results revealed that GO was a suitable adsorbent for the removal of cationic dyes from tannery effluents.

Synthesis of bio-oilphenol-formaldehyde resins under alkali conditions [Elektronička građa] : physical, chemical and thermal properties of resins and bonding performance = Sinteza bioulja s fenolformaldehidnim smolama u alkalnim uvjetima : fizička, kemijska i toplinska svojstva smola i svojstvo lijepljenog spoja / Günay Özbay, Caglar Cekic, Muhammad Syarhabil Ahmad, Erkan Sami Kokten. - Graf. prikazi.
Bibliografija: 45 jed. - Abstract ; Sažetak. - In the present study, bio-oil produced from vacuum pyrolysis of woody biomass has been investigated as a source of chemical feedstock. Bio-based resins were produced using the bio- oil with phenol substitutions ranging from 10 to 30 wt%. The conventional GC/MS analysis was carried out for the evaluation of the chemical composition of bio-oil. TGA, DSC and FT-IR analyses were used in order to characterize the bio-oil-phenol-formaldehyde (BPF) resins. The bonding quality of wood samples bonded with the BPF resins was investigated under different pre-treatment conditions. The highest shear strength was observed for the control samples bonded with the laboratory PF resin. As the amount of bio-oil was increased up to 30 wt%, the shear strength of the samples decreased from 12.08 to 11.76 N/mm2. The bonding performance was not negatively affected by the combination of bio-oil under dry conditions. According to TS EN 12765 standard, the relevant performance requirements for bonded samples under dry conditions must be at least 10 N/mm2. Relating to the standard, all samples bonded with BPF resins obtained the requirements for durability class C1. Under wet conditions, the bonding performance was negatively affected by the addition of bio-oil. However, the BPF resins fulfilled the durability requirements for C1, C2, and C3 specified in EN 12765 (2002). - U radu je predstavljeno istraživanje mogućnosti upotrebe bioulja dobivenoga vakuumskom pirolizom drvne biomase kao izvora kemijske sirovine. Biosmole su dobivene zamjenom 10 – 30 % mase (ili težinskog udjela) fenola biouljima. Analiza kemijskog sastava bioulja provedena je GC/MS metodom. Za karakterizaciju biouljnih fenolformaldehidnih smola (BPF) primijenjene su TGA, DSC i FT-IR analiza. Kvaliteta spoja uzoraka drva slijepljenih BPF smolama ispitivana je pri različitim uvjetima predobrade. Najveća čvrstoća na smicanje postignuta je na kontrolnim uzorcima lijepljenim laboratorijskim PF smolama. S povećanjem udjela bioulja do 30 % mase (ili težinskog udjela), čvrstoća na smicanje smanjila se s 12,08 na 11,76 N/mm2. Prema normi TS EN 12765, čvrstoća na smicanje u suhim uvjetima treba biti najmanje 10 N/mm2. Kombinacija bioulja s fenolformaldehidnim smolama nije negativno utjecala na svojstva slijepljenog spoja u suhim uvjetima i svi uzorci lijepljeni BPF smolama zadovoljili su zahtjeve klase trajnosti C1. U vlažnim uvjetima dodatak bioulja negativno je utjecao na svojstva slijepljenog spoja. Međutim, BPF smole ispunile su zahtjeve trajnosti za klase C1, C2 i C3 propisane normom EN 12765 (2002).

Textile market [Elektronička građa] : clothing industry facing new challenges / Ante Gavranović. - Ilustr.
Summary. - Fashion has serious economic, environmental and social effects. McKinsey’s Global Fashion Index states that over a hundred billion pieces of clothing are produced annually. A Greenpeace study shows that in Germany, for example, 60 new garments are bought per person per year. The production, transport and use of goods (washing, drying, ironing) cause more than 850 million tons of CO2 emissions each year. In short, it is an industry that is seriously damaging the environment. The fall in clothing prices in the last 20 years has enabled the purchase of an increasing number of garments. Analyses show that now, on average, we have five times more clothes than our grandparents had. This favourable trend in spending, however, also has its flip side of the coin: we feel great until we discover what is actually hiding behind this trend. In reality, this continuous accumulation of cheap clothes is possible only due to the constant reduction of production costs. This, in turn, has very serious consequences for our health, our planet, but also for the life and economic position of workers in the clothing and textile industry as a whole.

Textiles sustainability and communications [Elektronička građa] / Belinda Carp.
Summary. - The Industrial Revolution paved the way for industrialisation, economic growth and innovation, and resulted in the availability of an increased range of goods and services, improved life expectancy, and many other benefits. However, the rapid development has come at a cost which has not yet been settled. The earth’s natural resources are being used at a rate that cannot be sustained by the natural ecosystem and, according to the Chief Scientific Adviser to the UK government in 2009, we are heading for a "perfect storm" where a growing world population will demand yet more resources from an earth which simply cannot sustain demand.

Thermal degradation of bonding strength of aspen plywood [Elektronička građa] = Toplinska degradacija čvrstoće lijepljenja ploče od uslojenog drva jasike / Pavlo Bekhta, Nataliya Bekhta. - Graf. prikazi.
Bibliografija: 25 jed. - Abstract ; Sažetak. - The objective of this research was to study the effect of exposure time on the bonding strength of aspen plywood at elevated temperatures. The plywood samples were manufactured under laboratory conditions using two types of adhesive: urea-formaldehyde (UF) and phenol-formaldehyde (PF). The plywood samples were tested after exposure to three different temperatures (150 °C, 200 °C and 250 °C) and three exposure time levels (1, 2 and 3 hours) at each temperature. Additionally, a set of control samples was tested at room temperature. The quality of bonding was assessed by shear strength test in compliance with the requirements of the standard EN 314-1. The mass and density losses as well as colour changes of the plywood samples were also determined. The findings of this study indicated that exposure of plywood panels to elevated temperature caused significant degradation of their bonding strength. PF plywood samples lost 63.2 % of their initial strength after 3 h of exposure at 250 °C, while UF samples lost 65.9 % of their initial strength already after 3 h of exposure at the temperature of 200 °C. Statistical regression-based models were also developed for predicting the loss of plywood bonding strength as functions of mass and density losses and total colour difference. As the mass/density losses or total colour difference of panels increased, the losses in bonding strength increased too. - Cilj ovog istraživanja bio je ispitati utjecaj vremena izlaganja toplini na čvrstoću lijepljenja ploča od uslojenog drva jasike. Uzorci ploča od uslojenog drva proizvedeni su u laboratorijskim uvjetima uporabom dvije vrste ljepila: urea-formaldehidnog (UF) i fenol-formaldehidnog (PF) ljepila. Uzorci ploča od uslojenog drva ispitani su nakon izlaganja različitim temperaturama (150 °C, 200 °C i 250 °C) tijekom različitog vremena izlaganja (1, 2 i 3 sata). Usto, skupina kontrolnih uzoraka ispitana je pri sobnoj temperaturi. Kvaliteta lijepljenja ocijenjena je testom smične čvrstoće u skladu sa zahtjevima norme EN 314-1. Također, određeni su gubitci mase i smanjenje gustoće, kao i promjena boje uzoraka ploča od uslojenog drva. Rezultati ove studije pokazali su da izlaganje ploča od uslojenog drva povišenoj temperaturi uzrokuje znatno smanjenje njihove čvrstoće lijepljenja. Uzorci ploča od uslojenog drva zalijepljeni PF ljepilom izgubili su 63,2 % svoje početne čvrstoće nakon tri sata izlaganja na 250 °C, dok su uzorci ploča od uslojenog drva zalijepljeni UF ljepilom izgubili 65,9 % početne čvrstoće već nakon tri sata izloženosti temperaturi 200 °C. Nadalje, razvijeni su statistički regresijski modeli za predviđanje gubitka čvrstoće lijepljenja ploča od uslojenog drva kao funkcije gubitka mase, smanjenja gustoće i ukupne razlike u boji. Kako se povećavao gubitak mase, smanjivala gustoća ili povećavala ukupna razlika u boji ploča, tako su se povećavali i gubitci čvrstoće lijepljenja.

Weath ering performance of beech wood coated with acrylic paint containing UV stabilizers of dihydroxy benzophenone and nano zinc oxide [Elektronička građa] = Svojstva bukovine obrađene akrilnim premazom koji sadržava UV stabilizatore dihidroksi-benzofenon i nano cinkov oksid nakon izlaganja vremenskim utjecajima / Mehrnaz Akbarnezhad, Davood Rasouli, Hossein Yousefi, Mahdi Mashkour. - Ilustr. ; graf. prikazi.
Bibliografija: 31 jed. - Abstract ; Sažetak. - In this study, the effect of UV stabilizers (dihydroxy benzophenone and nano zinc oxide) on the weathering degradation of water-based acrylic coating on beech wood was investigated. The wood specimens were coated by brush and then weathered naturally for six months. The obtained results showed that the use of nano zinc oxide reduced color changes and mold growth on the surface of weathered samples. However, the results of contact angle, pull-off adhesion, colorimeter and FTIR revealed that the dihydroxyl benzophenone was not effective in preventing weathering degradation of coated wood. - U radu se prikazuje istraživanje utjecaja UV stabilizatora (dihidroksi-benzofenona i nano cinkova oksida) na razgradnju vodenoga akrilnog premaza na bukovini koja je bila izložena vremenskim utjecajima. Uzorci drva premazani su kistom, a potom su šest mjeseci prirodno izloženi vremenskim utjecajima. Dobiveni su rezultati pokazali da nano cinkov oksid smanjuje promjenu boje i pojavu plijesni na površini izloženih uzoraka. Međutim, rezultati kontaktnog kuta, adhezije, kolorimetrije i FTIR analize potvrđuju da dihidroksi-benzofenon nije učinkovit u sprečavanju razgradnje premazanog drva.

Wood sector media budget allocation [Elektronička građa] : comparison of Republic of North Macedonia and some South-Eastern European countries = Izdvajanja za medije iz proračuna tvrtki drvnog sektora : usporedba Republike Sjeverne Makedonije s nekim zemljama jugoistočne Europe / Ilijana Petrovska, Živka Meloska, Mira Stankević Šumanska, Angelina Meloska. - Graf. prikazi.
Bibliografija: 13 jed. - Abstract ; Sažetak. - The aim of this paper is to analyse and compare the official media reports published in the Republic of North (RN) Macedonia and some other South-Eastern European Countries, such as Croatia, Bosnia and Herzegovina, Serbia, and Bulgaria. According to the official results from Nielsen Arianna, IPSOS, and Alma Quattro, Macedonian furniture companies mainly allocate their media budget to television channels with an amount of EUR 4.786.710, which is 6.7 times lower than the amount allocated by Croatian furniture companies to the same media (EUR 32.223.506). The conclusion is that the media budget of Macedonian furniture companies is on a very low level, compared to selected South-Eastern European Countries, mainly because 74 % of the total number of furniture companies are micro enterprises with up to ten employees, which affects the media budget. - Cilj je ovog rada analiza i usporedba službenih medijskih izvještaja objavljenih u Republici Sjevernoj Makedoniji i u nekoliko drugih zemalja jugoistočne Europe poput Hrvatske, Bosne i Hercegovine, Srbije i Bugarske. Prema službenim rezultatima agencija Nielsen Arianne, IPSOS i Alma Quattro, makedonske tvrtke za proizvodnju i prodaju namještaja za medijske aktivnosti iz proračuna izdvajaju najviše sredstva za oglašavanje na televizijskim kanalima u odnosu na druge načine oglašavanja. Riječ je o 4 786 710 EUR, što je 6,7 puta manje od iznosa što ga izdvajaju hrvatske tvrtke za proizvodnju i prodaju namještaja za isti način oglašavanja (32 223 506 EUR). Iz toga se može zaključiti da je proračun medijskih aktivnosti makedonskih tvrtki za proizvodnju i prodaju namještaja na vrlo niskoj razini u usporedbi s nekim promatranim državama jugoistočne Europe. Razlog tomu je vjerojatno činjenica da su u Sjevernoj Makedoniji u ukupnom broju tvrtki za proizvodnju i prodaju namještaja 74 % njih mikrotvrtke koje imaju do deset zaposlenih, što utječe na izdvajanja iz njihova proračuna za medije.

Wood surface finishing of selected invasive tree species [Elektronička građa] = Površinska obrada nekih invazivnih vrsta drva / Matjaž Pavlič, Jure Žigon, Marko Petrič. - Graf. prikazi.
Bibliografija: 28 jed. - Abstract ; Sažetak. - Due to their strong renewal power, the invasive tree species are spreading rapidly, especially in abandoned agricultural and forest areas and along traffic routes and water courses. One way of their restriction is the promotion of their use. In our research, we investigated surface finishing of wood of five selected invasive species in Slovenia, Box elder (Acer negundo L.), Black locust (Robinia pseudoacacia L.), Horse-chestnut (Aesculus hippocastanum L.), Honey locust (Gleditsia triacanthos L.) and Chinese sumac (Ailanthus altissima (Mill.) Swingle), and compared it with the finishing of the European beech (Fagus sylvatica L.) wood. For coatings, we selected one-component waterborne finish on acrylate-polyurethane basis, one-component solventborne finish on polyurethane basis and tung oil as a natural finish. Several surface properties were investigated. We proved that surface hardness, resistance to impact and adhesion were very much related to interactions between the coating and the substrate, while resistance to cold liquids was only dependant on the type of the finish. It was also shown that, in general, finishing of woods of selected invasive tree species was not problematic. The only exception was Black locust wood on which tung oil cured very slowly. - Invazivne vrste drva brzo se šire zbog izrazito jakog svojstva obnavljanja, posebice na zapuštenim poljoprivrednim i šumskim površinama te uz prometnice i vodotokove. Jedan od načina ograničavanja njihova širenja jest poticanje uporabe njihova drva. U ovom smo istraživanju proučavali površinsku obradu pet invazivnih vrsta drva u Sloveniji: negundovca (Acer negundo L.), bagrema (Robinia pseudoacacia L.), divljeg kestena (Aesculus hippocastanum L.), gledičije (Gleditsia triacanthos L.) i pajasena (Ailanthus altissima (Mill.) Swingle), u usporedbi s površinskom obradom bukovine (Fagus sylvatica L.). Kao premazni materijali upotrijebljeni su jednokomponentni vodeni lak na bazi poliakrilata i poliuretana, jednokomponentni otapajući poliuretanski lak i tungovo ulje kao prirodni premazni materijal. Pritom je ispitivano nekoliko svojstava površine. Dokazano je da tvrdoća površine, otpornost na udarce i adhezija izrazito ovise o međudjelovanju premaza i podloge, a otpornost na hladne tekućine ovisi samo o vrsti premaza. Također je dokazano da površinska obrada promatranih invazivnih vrsta drva nije problematična. Izuzetak je drvo bagrema, na kojemu se tungovo ulje vrlo sporo suši.

Cigarette butts and waste coffee grounds as additives to brick clay [Elektronička građa] / Marina Jovanović, Adnan Mujkanović, Erna Tutić. - Ilustr., graf. prikazi.
Bibliografija: 26 jed. - Summary. - The paper analyses the influence of cigarette butts and waste coffee grounds addition on the properties of the brick clay. The waste materials were added to the clay in amounts of 5 wt.% and 10 wt.%. Standard consistency, plasticity, drying and firing behaviour and refractoriness were tested on the clay sample and the samples with wastes additions. Apparent density, apparent porosity, water absorption, strength and thermal conductivity were investigated on the samples fired at 1173 K. Addition of the waste materials improved thermal insulation characteristics and drying shrinkage, while other properties remain within the required limits for brick industry.

Probijanje "četvrtog zida" kao interaktivni postupak suvremenog umjetničkog stvaralaštva [Elektronička građa] / Miroslav Huzjak.
Bibliografija: str. 53-54. - Sažetak ; Summary. - Suvremena umjetnost izgubila je svoju likovnost, a ostala joj je samo vizualnost. S druge strane, prijelaz od likovne moderne ka nelikovnoj suvremenoj umjetnosti donio je i mnogo novosti; jedna od njih je tzv. ‘probijanje četvrtog zida’. Radi se o kazališnom (a zatim i filmskom) terminu koji označava trenutak kada se gledatelj na neki način interaktivno uključuje u predstavu, a likovi pokazuju svijest da su likovi u predstavi. Upravo će suvremena umjetnost istraživati postupke brisanja granica između umjetničkog i svakodnevnog čina, sugerirajući kako »sve je umjetnost« i »svaki čovjek je umjetnik«. Novo je doba donijelo otuđenost javnosti od znanosti i umjetnosti, ali i nova filozofska tumačenja medijskog krajolika i hiperrealnosti postmoderne. Hiperrealne postaju i digitalne igre, od kojih se neke temelje upravo na rušenju »četvrtog zida«. Zbunjene reakcije na tehniku rušenja »četvrtog zida« variraju u rasponu od verbalnih reakcija na performance, preko previše doslovnog shvaćanja filmova pa sve do tragičnih nesreća, čak i samoubojstava povezanih s određenim digitalnim igrama. To da stvarnost oponaša hiperstvarnost postalo je uobičajeno, ali otvorilo se i pitanje: može li suvremeni pojedinac s time izaći na kraj?. - Modern art has lost its artistic character; only its visual aspect remains. On the other hand, the transition from modern fine arts towards non visual contemporary art has brought a great deal of novelties; one of these is “breaking the fourth wall”. This is a theatre (and film) term referring to moments when viewers become interactively involved in a play, and the characters become aware that they are characters in a play. Modern art has explored processes by which the border between artistic acts and everyday acts is erased, suggesting that “everything is art” and “every man is an artist”. The new era has caused the public to become alienated from science and the arts, but has also provided new philosophical interpretations of media landscapes and the hypperealism of the post-modern. Digital games are also becoming hyperrealistic, and some of these are founded on demolishing the “fourth wall”. Confused reactions to techniques of breaking the “fourth wall” vary from verbal reactions to a performance and excessively literal perceptions of film to tragic accidents or even suicides connected with particular digital games. Hyperreality mimicking reality has become commonplace, however the question arises: can the modern individual deal with this?.

City brand image formation by urban heritage initiatives [Elektronička građa] / Miglė Černikovaitė, Žaneta Karazijienė. - Graf. prikazi.
Bibliografija: 30 jed. - Summary ; Sažetak. - In today's world, as cities compete in the marketplace, strategies for creating a city brand image are often shaped solely to meet the aspirations of profit, business development, and awareness. The preservation of culture, historical, and urban heritage remains important only in urban development strategies and not in actual development actions. The truth is, the image of a city is shaped by different historical, political, demographic, sociological, and economic factors which make up what we perceive as the brand image of a city. However, one of the most noticeable elements of the brand image of a city is the urban heritage based on national traditions. The aim of this article is to evaluate the effects of urban heritage initiatives in the creation of the brand image of the city of Vilnius. Research methods used in this article are qualitative content analysis and expert semi-structured interviews. Main conclusions stimulate debate, hesitation and criticism from communities and city researchers for using new heritage object and culture initiatives in order to create the brand image of Vilnius. The influence of urban heritage is inevitable when modelling the brand image of Vilnius, but there are no effective strategies to deal with the new urban heritage initiatives by creating the brand image of Vilnius yet. - U današnjem svijetu, dok se gradovi natječu na tržištu, strategije stvaranja imidža nekoga grada često se izrađuju samo kako bi se udovoljilo težnjama za profitom, poslovnim razvojem i osviještenosti. Očuvanje kulture, te povijesne i urbane baštine ostaje važno samo unutar strategija urbanog razvoja, a ne i prilikom stvarnog djelovanja usmjerenog na razvoj. Istina je da sliku grada oblikuju različiti povijesni, politički, demografski, sociološki i ekonomski čimbenici koji čine ono što doživljavamo kao imidž grada. Međutim, jedan od najuočljivijih elemenata imidža grada je urbana baština utemeljena na nacionalnoj tradiciji. Cilj ovoga članka je procijeniti učinke inicijativa urbanog naslijeđa u stvaranju imidža grada Vilniusa. Prilikom istraživanja korištene su kvalitativna analiza sadržaja i polustrukturirani intervjui sa stručnjacima. Glavni zaključci potiču raspravu, oklijevanje i kritiku od strane zajednica i istraživača grada koji koriste nove objekte baštine i kulturne inicijative kako bi stvorili imidž grada Vilniusa. Utjecaj urbane baštine neizbježna je sastavnica prilikom oblikovanja imidža grada Vilniusa, ali još uvijek nema učinkovitih strategija koje bi se bavile novim inicijativama urbane baštine pri stvaranju imidža grada Vilniusa.

Građevni redovi i regulatorno planiranje Zagreba od 1900. do 1918. godine [Elektronička građa] / Zlatko Jurić. - Graf. prikazi.
Bibliografske bilješke uz tekst ; bibliografija: str. 50-51. - Sažetak ; Summary. - Nakon neuspjeloga pokušaja zagrebačkoga gradskog načelnika Adolfa Mošinskog i vijećnika Adolfa Hudovskog da se donese građevni red 1894., godine 1908. i 1909. traje rasprava o tri varijante (smjera) realizacije novoga prijedloga građevnoga reda grada Zagreba, koje su razrađene i analizirane u ovome članku. Prva je varijanta Vladoja Eisenbarta, koji je nastavio i razradio ideju građevnoga reda kao jednoga od osnovnih instrumenata u reguliranju gradova. Eisenbartov tekst iz 1908. preradio je kolektiv autora brojnim primjedbama nakon dugotrajne rasprave u konačni prijedlog iz 1909. godine. Drugu varijantu zagovarali su inženjeri Antun Kostial st., Mirko pl. Ferrich, Kamilo Bedeković i odbor Hrvatskoga društva inžinira i arhitekta, koji su Eisenbartov prijedlog iz 1908. promatrali na dvije razine. Oni su odbacili ideju i svrhu građevnoga reda kao isključivo regulatornoga dokumenta i pretvorili ga u razvojni gospodarski dokument. Odbor se neočekivano preobrazio u žestokoga zagovornika privatnoga vlasništva i poduzetništva. Treću varijantu zastupao je gradski načelnik dr. Milan Amruš, koji je forsirao osnivanje građevnoga odbora i bitno smanjivanje ovlasti i važnosti Gradskoga poglavarstva i zastupstva. Glavni problem u prijedlogu bilo je uvođenje građevnoga odbora kao posebne građevne oblasti koja bi s predloženim ovlastima suspendirala građevnu oblast prve molbe (Gradsko poglavarstvo) i kontrolno djelovanje Gradskoga zastupstva. Bez obzira na postojeće stranačke podjele i osobne animozitete zastupnika, prijedlog osnove građevnoga reda iz 1909. nije imao nikakve izglede prilikom glasanja u Gradskom zastupstvu. - After the unsuccessful attempt of Zagreb mayor Adolf Mošinski and councillor Adolf Hudovski to secure approval for the Master Plan of 1894, a discussion on three variants (directions) of realising a new master plan of Zagreb took place in 1908 and 1909. This paper elaborates and analyses these three proposals of realising the Zagreb master plan. The first is the variant of Vladoje Eisenbart, who continued and elaborated the idea of the Master Plan as one of the basic instruments in urban regulation. Eisenbart’s text from 1908 was revised by a collective of authors and was, following numerous objections and long discussions, formed into a final proposal in 1909. The second variant was advocated by Antun Kostial, Sr, Mirko Ferrich, Kamilo Bedeković, and a committee of the Croatian Society of Engineers and Architects, who viewed Eisenbart’s 1908 proposal on two levels. They rejected the idea and purpose of the master plan as an exclusively regulatory document, and transformed it into a development and economic document. The committee unexpectedly changed into a fierce advocate of private ownership and entrepreneurship. The third variant was advocated by the mayor, Dr Milan Amruš, who forced the founding of a construction committee and substantial limitation of the powers and importance of the city government and council. The main problem in this proposal was the introduction of a construction committee as a separate construction authority that would have, using the proposed powers, suspended the construction authority of the first instance (the city government) and the overseeing activities of the city council. Regardless of the existing party divisions and personal animosities of the city government members, the master plan proposal of 1909 stood no chance at the city council vote.

Zagrebačka stanogradnja u prijedlozima planova i generalnim urbanističkim planovima od 1945. do 1990. [Elektronička građa] / Lidija Bencetić. - Ilustr., graf. prikazi.
Bibliografske bilješke uz tekst ; bibliografija i izvori: str. 416-418. - Sažetak ; Summary. - Rješenje stambenoga pitanja svakoga člana društva, kao i kvaliteta njegove realizacije, jedan je od ključnih izazova svakoga društva kao cjeline, ali i svakoga političkog sustava. U razdoblju socijalizma to je pitanje jedan od glavnih društvenih i političkih problema, koji se na razini gradova nastojalo riješiti kreiranjem sveobuhvatne stambene politike koja se pokušala ostvariti generalnim urbanističkim planovima i urbanističkim programima. U gradu Zagrebu na toj se problematici radilo kontinuirano u Urbanističkom zavodu grada Zagreba i njegovim pravnim prethodnicima, prije svega preko urbanističkih prijedloga i planova objavljenih 1949., 1953., 1965., 1971. i 1986. godine. Istraživanje se temelji na generalnim urbanističkim planovima Zagreba (regulatorne osnove), jednome programu urbanističkoga razvoja i dva prijedloga urbanističkoga razvoja: Vlado Antolić, „Regulacioni plan i direktivna regulaciona osnova Zagreba” (1949.); Zagreb: direktivna regulatorna osnova Zavoda za urbanizam NOGZ 1953. (1953.); Urbanistički program grada Zagreba: smjernice za razvoj (1965.); Generalni urbanistički plan grada Zagreba: elaborat (1970.); Generalni urbanistički plan grada Zagreba: sažetak (1985.). Ovim se radom nastoji ustanoviti koja su sustavna rješenja predviđena, kakve su bile projekcije razvoja grada i kretanje broja stanovništva te kakva je bila realizacija urbanističkih prijedloga i planova. - The issue of securing housing for each member of a society as well as the quality of its construction are among the key challenges faced by every society as a whole, but also by every political system. Housing was one of the main social and political issues during the socialist period in Croatia. In urban areas, the goal was to create an all-encompassing housing policy that would be implemented via master plans and urban planning programmes. This problem was worked on continuously by the Urban Planning Institute of Zagreb City and its legal predecessors, primarily through urban planning proposals and plans published in 1949, 1953, 1965, 1971, and 1986. The research presented here is based on the master plans of Zagreb (regulatory bases), one urban development programme, and two urban development proposals: Vlado Antolić, ‘Regulacioni plan i direktivna regulaciona osnova Zagreba’ [Regulatory Plan and Directive Regulatory Basis of Zagreb], Arhitektura (1949); Zagreb: direktivna regulatorna osnova Zavoda za urbanizam NOGZ 1953. [Zagreb: Directive Regulatory Basis of the Zagreb City People’s Committee Urban Planning Institute, 1953] (1953); Urbanistički program grada Zagreba: smjernice za razvoj [Urban Planning Programme of the City of Zagreb: Development Guidelines] (1965); Generalni urbanistički plan grada Zagreba: elaborat [Zagreb City Master Plan: Report] (1970); Generalni urbanistički plan grada Zagreba: sažetak [Zagreb City Master Plan: Summary] (1985). This paper attempts to determine which systemic solutions were anticipated, what were the projections of the city’s development and population trends, and how the urban planning proposals and plans were implemented.

Evaluation of the effective factors on social interactions in the design of public libraries [Elektronička građa] / Reza Askarizad. - Ilustr. ; graf. prikazi.
Bibliografija: 33 jed. - Abstract. - Nowadays, the interaction of people in the world is deemed a controversial topic and consequently, the creation of an appropriate context for interacting with individuals is one of the issues that is considered by architects in many designs. In this research, it has been endeavored to consider the factors affecting social interactions in the design of public libraries through the descriptive-inferential analysis. The results of this research reveal that in the architectural spaces that have been designed with open-configured plans, spatial integrity and sociability will increase. On the other hand, the factors such as depth and the level of privacy are also reduced. Therefore, in designing a public library with an approach toward social interaction, there should be a variety of open and closed-configured spaces in the plan that allow users to choose the space they optionally want and in which they would enjoy in their own presence by choosing their own activities.

The main directions of the humanization of industrial objects in urban environment [Elektronička građa] / Maksym Votinov, Olga Smirnova, Maria Liubchenko. - Graf. prikazi.
Bibliografija: 27 jed. - Abstract. - The tendency to transform the old industrial areas began in 1950-1960 last century in Europe and America. By the end of the twentieth century with the development of the world economy, the time has come when the transformation of industrial infrastructure is becoming a comprehensive phenomenon. Currently, in the economies of developed countries, forms of transformation such as global mergers, takeovers, re-equipment and re-functioning are being intensively implemented. Based on the analysis of positive foreign experience, the main directions of humanization of the urban environment are considered through the transformation of industrial facilities. The transformation of industrial facilities and their territories with a change in functionality becomes the main direction of humanization of the urban environment in the XXI century. Numerous architectural and compositional techniques are allowed to adapt any industrial facility in the dynamic infrastructure of the city.

Support of decision in buildings refurbishment with a change of utility [Elektronička građa] / Aleksandra Radziejowska, Anna Sobotka, Joanna Sagan. - Ilustr.
Bibliografija: 25 jed. - Abstract. - Construction objects, including buildings, are characterized by a long period of use resulting from the properties of structural and material solutions properly designed, constructed and operated. Practice shows that functional aging of buildings is faster than technical. Therefore, for these reasons and taking into account current socio-economic concepts (sustainable development, preservation of cultural heritage, economic, location reasons, etc.) buildings that have ceased to perform their current function are subject to renovation and / or refurbishment, enabling them to perform new functions compatible with social needs: public and commercial. The choice of new functions cannot be accidental. The decision-making process regarding the refurbishment of a building with a change of utility function is subject to high economic risk, which is why it should be carried out using a methodology that ensures a holistic approach. The paper proposes a methodology of functional and functional programming in the pre-investment phase of project preparation using multi-criteria analysis of the utility function selection. The methodology is illustrated by an example of the choice of function in the adaptation of a post-production building from public resources.

"Mjuzica.hr" kao poduzetnički projekt u modelu glazbene streaming platforme [Elektronička građa] / Joško Lozić. - Graf. prikazi.
Bibliografija: 29 jed. - Sažetak ; Summary. - Stara je medijska industrija ušla u razdoblje potpune transformacije proizvodne i menadžerske paradigme. Klasična medijska industrija, stvorena u krilu moderne, razvila se tek uz industrijsku proizvodnju i masovno oglašavanje. Glazbena je industrija nastala početkom 20. stoljeća razvojem radio prijemnika, a svoj će vrhunac vezati uz televiziju i „broadcasting“. Cilj je ovog rada otvoriti novi horizont u promišljanju razvoja novih medijskih odnosno glazbenih industrija i poduzetničkih projekata iz toga područja industrije. Model distribucije proizvoda glazbene industrije, kao fizičkih proizvoda u obliku gramofonskih ploča i prodaje u „brick-and-mortar“ prodavaonicama, zamijenjen je distribucijom na glazbenim streaming platformama. Poslijemoderno je društvo promijenilo naviku posjedovanja fizičkih nosača glazbenih zapisa u pretplatu na streaming servisu. Danas već posluje više globalnih streaming platformi koje distribuiranju glazbeni sadržaj te su višestruko prerasle oblike poduzetničkog projekta. Mjuzica.hr zamišljena je kao poduzetnički poduhvat u segmentu streaming platformi za hrvatske glazbenike. - The old media industry has entered a period of complete transformation of the production and management paradigm. The classical media industry, created in the lap of modernity, developed only with industrial production and mass advertising. The music industry originated in the early 20th century with the development of radios, and its peak will be associated with television and "broadcasting". The aim of this paper is to open a new horizon in considering the development of new media and music industries and entrepreneurial projects in this field of industry. The model of distribution of music industry products, such as physical products in the form of gramophone records and sales in "brick-and-mortar" stores, has been replaced by distribution on music streaming platforms. Postmodern society has changed the habit of owning physical music carriers to subscribe to a streaming service. Today, there are already several global streaming platforms that distribute music content and have outgrown the forms of entrepreneurial project. The music streaming platform that distributes the music content of Croatian artists, as a form of entrepreneurial project, is still waiting for entrepreneurs who are ready to try their hand at this entrepreneurial venture.

Apstraktni film [Elektronička građa] : izlagačko-doživljajna obilježja / Vanja Obad. - Ilustr.
Tema broja: Filozofija pokretnih slika (I.). - Bilješke uz tekst. - Bibliografske bilješke uz tekst ; bibliografija: str. 565-567. - Sažetak ; Abstract. - U članku se razmatra specifična svrha postupaka i doživljaja koje nastoje generirati različite eksperimentalističko-filmske struje apstraktnog filma. Namjera je prikazati na koji način apstraktni film zaokuplja našu pažnju te pokazati kako on upravo i računa na tip raspoloženja u situacijama odmaka od nužde snalaženja (kauzalne logike), na prepuštanje percepciji neobičnih vizualno-zvukovnih nadražaja koji potiču drugačija emotivna i asocijativna polja. Analizirat će se izlagački elementi različitih struja apstraktnog filma, oslanjajući se prvenstveno na klasične primjere apstraktnog filma i animacije (braća Whitney, McLaren, Richter i Eggeling i dr.). - The paper elaborates specific perceptive purposes and structural procedures generated by the various experimental abstract films and shows the ways how abstract film engages spectator’s attention. By “liberating” our visual system from representational (daily visual) experience, the abstract film encourages us to cultivate different sensory and sensual sensibility, explore new associations and alternative paths for moods and emotions. Various streams of abstract film will be analysed, relying primarily on classical abstract films (Whitney brothers, McLaren, Richter, and Eggeling, etc.).

Čitati Bergmanov arhiv [Elektronička građa] / Janica Tomić.
Tema broja: Filozofija pokretnih slika (I.). - Bibliografske bilješke uz tekst ; bibliografija: str. 582-583. - Sažetak ; Abstract. - Od godine 2018. dostupan javnosti, arhiv Ingmara Bergmana potaknuo je niz čitanja i revalorizacija, prije svega, tekstualnog dijela njegova opusa. Promišljajući odnos Bergmanovih rukopisa i filmova, u radu se ukazuje na značaj radnih dnevnika (1938. – 2006.) i drugih tekstualnih fragmenata za shvaćanje Bergmanova arhiva, u cjelini, kao umjetnosti. Zaključna analiza filma Pričesnici (Nattvardsgästerna) ilustrira kako isprepleteni dijelovi arhiva pridonose shvaćanju posebno ranije previđenih afektivnih slojeva, nadovezujući se i na teze o potrebi razrade uvriježenih filozofskih i srodnih pristupa Bergmanovu radu. - Publically available since 2018, the Ingmar Bergman Archives gave rise to a wide range of readings and re-evaluations of primarily the written part of his oeuvre. While considering the relation between Bergman’s manuscripts and films, the paper points out the significance of his workbooks (1938 – 2006) and other textual fragments for understanding the Archives as a work of art. The concluding analysis of the film Winter Light (Nattvardsgästerna) illustrates how the intertwined parts of the Archives contribute to understanding its appeal throughout the history of readings. By highlighting the previously neglected affective layers of the film, the paper also builds on hypotheses about the need to expand on existing philosophical and theoretical approaches to Bergman’s work.

Film costume as a visual narrative element [Elektronička građa] : defining the abstract emotions of the film viewer via Plutchik's wheel of emotions / Jelena Vojković.
Bibliografija: 18 jed. - Summary. - This research is an attempt to try to define the semiotic elements of film costumes that result with certain final feelings of the viewer. Looking through the semiotic theory of both Roland Barthes and Walter Benjamin and the specifics of (theatre and) film costume as a means of influencing the viewer and his/her thoughts, feelings and overall catharsis, the identity of a certain film has been set through an analysis of various elements. Furthermore, it has been noticed that psychological results by one observing a film can be various and lean more on known philosophical and psychological tendencies i.e. Freud’s theories or the ones of M. Merleau-Ponty or Lacan. To make it less verbatim, the example for the analysis that has been chosen is the 1982 science fiction film Bladerunner directed by Ridley Scott. With surreal messages and multi-layered meanings of its visual and audio presentation, it seemed like a perfect starting point for the research of the subconscious mind of the viewer. Finding a non-invasive approach to viewer’s impression, the costume itself could be observed both independently and in correlation with other film elements. By combining the results of all film levels via a visual psychological test by Robert Plutchik, known as Plutchik’s wheel of emotions, it is plain to see that a final impression still lies in a personal analysis. We find a prevalence of certain thoughts that lead the viewer to change his/her perception and, ultimately, to catharsis.

Filmski spektakl i kinematička kultura [Elektronička građa] : filmski horor u doba slike svijeta / Dario Vuger.
Tema broja: Filozofija pokretnih slika (I.). - Bibliografske bilješke uz tekst. - Sažetak ; Abstract. - U radu autor uspostavlja i brani tezu o postavljanju filma strave osamdesetih godina prošloga stoljeća kao paradigme djelovanja spektakla kao sustava udaljavanja pojedinca od života njegovim bitnim vezanjem za slikovne fenomene. Time se u svezu dovode tri do sada odvojena elementa koje autor smatra presudnim za razumijevanje medija te ukupne medijske teorije dvadesetog i prvih desetljeća dvadeset i prvog stoljeća, a to su Heideggerova ideja o dobu slike svijeta, Debordov pojam spektakla i Deleuze-Bellerova filozofija filma i napose konceptualno određena filmska filozofija kao sažimanje mogućnosti odgovora na suvremeno stanje društva u kojemu se filmski spektakl odražava u bitno kinematiziranoj kulturi, odnosno društvu pokrenutom kroz isključiv odnos slikovnih reprezentacija. - In this paper, the author establishes and defends the thesis that the 1980s horror film production acts as a paradigm of the spectacle, especially in terms of the system of reduction of immediate life to image related mediations and phenomena. Thus, three disparate elements are now connected in a conceptual framework by which author supposes one must judge the media theory and media at large at the end of the twentieth and the beginning of the twenty-first century. The three elements are the Heideggerian notion of the age of the world-picture, the Debordian notion of the spectacle, and the Deleuzian experiment of the philosophy of film that, through Beller, establishes itself as a film philosophy, to be a possible answer to the contemporary state of a society in which the film spectacle reflects itself in the essentially cinematic culture, that is, in society put in motion exclusively only through the relation of image representations.

Građenje raspoloženja filmom kao postupak poetizacije [Elektronička građa] / Hrvoje Turković.
Tema broja: Filozofija pokretnih slika (I.). - Bibliografske bilješke uz tekst ; bibliografija: str. 537-540 ; filmografija: str. 540. - Sažetak ; Abstract. - Visokoumjetnička dostignuća u dugotrajnoj tradiciji zapadnjačke estetičke misli vezuju se uz postizanje poetičnosti, a ova uz pobuđivanje osjećaja, pa se i u filmskoj tradiciji poetičnost uspostavljala kao ideal paradigmatski umjetničkog dostignuća filma. No, među različitim tipovima osjećaja kojima raspolaže čovjek, poetska djela ciljaju u pravilu na pobuđivanje nekog općeg raspoloženja, a ne neke izričite emocije. U radu se prvo daje pregled razlika između emocija i raspoloženja, potom se na primjeru uvodne scene u filmu Građanin Kane demonstrira kojim se različitim sredstvima u opisno orijentiranoj uvodnoj sceni postiže određen ‘ugođaj’ (turobno raspoloženje). Pitanje je, međutim, kako se opisanim heterogenim stilskim sredstvima može pobuditi vrlo specifično, jedinstveno, holističko raspoloženje. Odgovor je, ukratko, u tome da jednako kao što raspoloženja utječu na selektivan odnos prema okolini, birajući u njoj za percepciju one aspekte koji su sukladni, kongruentni s osnovnim karakteristikama određenog raspoloženja, tako i filmski stvaratelji biraju onaj repertoar stilskih značajki danoga filma što je kongruentan s ciljanim raspoloženjima kako bi ih pobudili u gledatelja koji prepušteno gleda film. - High artistic achievements were repeatedly connected with poetry in the tradition of Western aesthetical thought, and the poetry with eliciting emotions. The same has happened within the tradition of film reviewing and theorising: poetry has been repeatedly evoked as a paradigmatic artistic achievement of particular films. But among the different affective states that can be elicited in humans by arts, attribution of ‘poetry’ typically addresses the eliciting and articulation of particular general moods, not the specific, episodic, short-term emotions. In this paper, specified are the differences among emotions and moods, and how a distinct (‘dark’) mood is achieved is demonstrated by the close analysis of the introductory descriptive scene in the film Citizen Kane. However, the crucial question is how very different and heterogeneous stylistic means pointed out in the analysis of the scene could elicit a particular, unique, holistic mood. In short, the answer is given by understanding that in the same way in which the moods selectively regulate our relations toward the world, choosing for the perception mood-congruent features of the world to sustain a particular mood, so the filmmakers choose a repertory of stylistic solutions congruent with the selectivity of the intended mood to elicit it in the immersed film viewer.

Jezik boli - između epistemološke asimetrije i biološki zadane društvenosti [Elektronička građa] / Cecilija Jurčić Katunar.
Bibliografija: str. 607-610. - Sažetak ; Abstract. - Kako je bol fenomenološki dostupna tek nositelju iskustva, što predstavlja prepreku objektivne kategorizacije u jezičnome mediju, želeći je učiniti dostupnom za sugovornika, pacijenti opisuju bol detaljnim i elaboriranim metaforičkim scenarijima, najčešće onima koji se odnose na neki oblik oštećivanja tijela – osiguravajući takvim utjelovljenim metonimijskim i metaforičkim profiliranjima adekvatnu imaginativnu simulaciju subjektivna iskustva za primatelja, neophodnu za razvijanje empatije. Rad donosi pregled filozofijskih razmišljanja o fenomenologiji boli, kao i pregled suvremenih neuroznanstvenih istraživanja o snažnoj biološki utemeljenoj društvenoj dimenziji boli, a onda i rezultate kognitivno-lingvističke analize vokabulara boli na korpusima pridjevskih deskriptora iz upitnika za procjenu boli McGill, te autentičnih dijaloga između liječnika i pacijenta. - Since pain, as a phenomenon, is accessible only to the person who experiences it (which represents an obstacle to the objective categorization in the linguistic medium), when patients want to make it available to their interlocutors, they describe it with very detailed and elaborate metaphorical scenarios, most often those relating to a form of body damage. Using such embodied metonymic and metaphorical definitions, they provide an adequate imaginative simulation of their subjective experience for their recipients. The paper presents an overview of philosophical insights on the phenomenology of pain as well as a review of contemporary neuroscience research on a social dimension of pain, but also the results of cognitive linguistic analysis of pain vocabulary based on descriptors from the McGill Questionnaire as well as on the corpus of authentic doctor-patient dialogues.

Croatian Shtokavian grammar books [Elektronička građa] : overview of the history of grammar books on the Croatian Shtokavian literary language with an outline of their periodization and classification / Sanda Ham. - Graf. prikazi.
Bibliografija: str. 20-21. - Summary. - This paper describes the criteria for the systematic periodization of Croatian grammar books. These criteria are exclusively linguistic and take into account the phonological and morphological structure described in these grammar books; where the grammar books contain a dictionary, the lexical organization has been taken into consideration as well. Based on these criteria, all Croatian grammar books may be systematized into four periods: I. 1604 – 1836 (old Croatian grammars), II. 1836 – 1899 (Croatian grammars from the Illyrian Movement to the end of the 19th century, with two parallel subgroups: grammars by the Zagreb School and Croatian Vukovians), III. 1899 – 1986 (with three successive subgroups: Croatian grammars from the beginning of the 20th century to 1940, Croatian grammars from 1940 to 1945, Croatian grammars from 1945 to the 1970s), IV. contemporary Croatian grammars. All these grammars clearly reveal the continuity of the Croatian literary language. This language is recognizable and comprehensible in all grammars, primarily owing to its Shtokavian stylization – and not to any kind of "organic basis".

Dječja lektira i novi mediji [Elektronička građa] / Marinko Lazzarich, Antonia Čančar. - Graf. prikazi.
Bibliografske bilješke uz tekst ; bibliografija: str. 167-169. - Sažetak ; Summary. - Kulturu čitanja oblikuje niz individualno i društveno određenih čimbenika koji proizlaze i iz kulturne tradicije neke sredine zbog čega je status knjige neodvojiv od cjelokupnoga vrijednosnoga sustava pojedinoga društva. Učitelj materinskoga jezika ključna je figura u procesu literarnoga sazrijevanja buduće čitateljske publike, a njegova je uloga otežana društvenim promjenama u današnjem "računalnom" svijetu gdje su položaj čitatelja i knjige bitno izmijenjeni u odnosu na ne tako davnu prošlost. Ne možemo u svemu kriviti digitalne medije, pa tako ni za smanjeni interes učenika za čitanje knjiga. U ovom radu raspravljat će se o složenosti obrazovnoga područja, o kulturi čitanja u novonastalom online okruženju te o promjenama koje donosi aktualni predmetni kurikul za Hrvatski jezik. Kritički će se razmotriti prednosti i nedostatci uporabe informacijsko-komunikacijske tehnologije u odgojno-obrazovnome procesu te ponuditi smjernice za funkcionalnu primjenu mrežnih alata i gotovih aplikacija u nastavi Hrvatskoga jezika. Dječje je odrastanje usko povezano s digitalizacijom i društvenim mrežama čiji utjecaj ne mora biti negativan, samo ga treba funkcionalno iskoristiti i usmjeriti pozornost neupitnom potencijalu dobre knjige. Istaknut će se (ne)opravdanost obvezne školske lektire i problem neuvažavanja čitateljskih interesa učenika mlađe školske dobi. U radu će biti ponuđen metodički predložak za interpretaciju lektirnoga naslova uz primjenu kreativnih mrežnih alata. - The culture of reading is shaped by a number of individually and socially determined factors arising from the cultural tradition of a given environment, making the status of books inseparable from the entire value system of a given society. The teacher of the native tongue is a key figure in the process of literary maturation of the future reading public; the role of the teacher is hindered by social changes in the modern "digital" world, in which the position of the reader and the book are now significantly different than in the recent past. Digital media cannot be solely blamed for the reduced interest of pupils in reading books. This paper will discuss the complexity of the field of education, the culture of reading in the new online environment, and changes brought by the current Croatian language subject curriculum. The advantages and disadvantages of using IT technologies in educational processes will be critically examined; guidelines will also be offered for the functional implementation of internet tools and ready-made applications in Croatian language teaching. Children’s upbringing is closely tied to digitalisation and social networks, the influence of which are not necessarily negative; this influence must simply be used functionally to direct attention towards the unquestionable potential of good books. The justification (or lack thereof) for required reading will be noted, as will the problem of disregarding the reading interests of young pupils. The paper will offer a methodical contribution for the interpretation of required reading titles through the implementation of creative online tools.

Obraćenje na katoličanstvo u Durtalovom romanu J.-K. Huysmansa [Elektronička građa] / Frano Vrančić.
Bibliografske bilješke uz tekst. - Sažetak ; Summary. - Cilj članka je istražiti temu Huysmansova vjerskog obraćenja u onome što književni kritičari obično nazivaju Durtalovim romanom. Autor rada ponajprije promatra originalnost tog pomalo zaboravljenog književnika s kraja XIX. i početka XX. stoljeća, kao i utjecaj ideje dekadencije na njegovo pisanje. Zatim će pokušati pokazati, naslanjajući se na djela stručnjaka za Huysmansovo djelo, zašto se piščev književni i duhovni smjer mijenja te kako se povratak katoličkoj vjeri očituje u „Durtalovu ciklusu“ (Le cycle de Durtal), tetralogiji koja na scenu dovodi isti glavni lik, Durtala, kroz kojeg autor romana „Tamo“ (Là-Bas) pripovijeda o etapama vlastitog puta u Damask. - This article aims to examine Huysmans' religious conversion in what literary critics usually call Roman de Durtal. Firstly, the author of the paper observes the originality of this almost forgotten fin-secular writer as well as the Decadence influence on his writing. Secondly, by referring to Huysmansian specialists, he tries to show why the literary and spiritual orientation of this multi-faceted writer changes course and how the return to the Catholic faith is manifested in The Durtal Cycle (Le cycle de Durtal), a tetralogy featuring the same main character - Durtal – and through whom the author of Down There (Là-Bas) tells us the stages of his own path to Damascus.

Elementi impresionizma u Moru Đure Sudete [Elektronička građa] / Melanija Ivezić Talan, Dean Slavić.
Bibliografske bilješke uz tekst. - Sažetak ; Summary. - Članak tumači impresionističke elemente u pripovijetci „Mor“ Đure Sudete pozivajući se poglavito na postavke o impresionizmu Viktora Žmegača, teorije lirskoga Emila Staigera i percepcije zbilje Ernsta Macha. Autori proučavaju odnose ljudskoga tijela i prirode, probleme vremena i subjekta te iznose modernističke elemente nestabilnosti subjekta u obzoru glavnoga lika Mora, protagonistkinje Šu i njezina oca. Tekst također ukazuje na stilsku blizinu Sudetina Mora s drugim junacima iz modernističkoga razdoblja hrvatske književnosti, osobito Leskovarovih Marcela Bušinskoga i Đure Martića te Kozarčeva Đuke Begovića. - The article interprets the elements of Impressionism in the novella Mor by Đuro Sudeta, relying on the postulates of Impressionistic literature as expounded by Victor Žmegač, on the theories of lyric style by Emil Staiger, and the perception of reality by Ernst Mach. The authors examine the relations of the human body and nature, problems of time, and the Modernist elements of unstable subjectivity in the scope of the main protagonist Mor, the leading female character Šu and her father. The text also shows the closeness of Mor and other heroes of the Modernist period in Croatian literature, such as Leskovar’s Marcel Bušinski and Đuro Martić; and Đuka Begović, the hero of the eponymous novel by Ivan Kozarac.

VYROUBAL, Vlasta
Correlation between social status and health in early medieval Dalmatia [Elektronička građa] / Vlasta Vyroubal, Željka Bedić, Anita Adamić Hadžić, Mario Šlaus. - Graf. prikazi.
Bibliografske bilješke na kraju teksta. - Abstract ; Sažetak. - The early mediaeval period in Croatia is rarely mentioned in historical sources. The development of society during this period was greatly influenced by formation of communities, within which there were many inequalities. The social group one belonged to and its ordinance were the main factors in the material and spiritual life of mediaeval man. Within Croatia, during the Early Middle Ages the process of social disintegration and the formation of social groups/strata varied from area to area. However, it can be deduced that this process was the quickest and most complete in the most socially-developed area – the Eastern Adriatic coast. The basic hypothesis of this paper is that people who belonged to different social groups also had different living conditions, which was reflected in their health, quality of life and lifespan. An individual's social status was assessed using the archaeological context, i.e. form of burial. The assumption was made that differences in status were reflected in the manner of the burial. The criteria used to determine social status were grave architecture and quantity and quality of grave finds and goods. In order to assess the health of the individuals anthropological methods were used. These methods included the assessment of age and sex, as well as the analyses of pathologies that leave traces on dry bones. Multivariate statistical methods showed that even though there were social inequalities in the early mediaeval society, the individuals belonging to higher-ranking groups had neither better health, nor lived longer. The results of the analyses carried out in the course of this work show that even though social stratification did exist in the early mediaeval society, biological sex was a much more important factor in life expectancy and quality of life than which social group an individual belonged to. - Razdoblje ranog srednjeg vijeka gotovo se uopće ne spominje u povijesnim izvorima. Društvena zajednica imala je vrlo bitnu ulogu u razvoju ranosrednjovjekovnog društva u Hrvatskoj. Unutar svake zajednice postojalo je mnoštvo razlika, a način i vrsta zajednice ovisili su o mnogo čimbenika. Pripadnost društvenoj grupi i njene staleške karakteristike bile su glavne odrednice u materijalnom i misaonom životu srednjovjekovnog čovjeka. Proces raslojavanja i stvaranja socijalnih grupa u Hrvatskoj u razdoblju ranog srednjeg vijeka bio je višestruko neujednačen, a najbrži i najpotpuniji je bio na društveno najrazvijenijem području, odnosno istočnoj obali Jadrana. U radu su prikazani rezultati antropološke analize zdravlja i kvalitete života starohrvatske populacije pokopane na nalazištu Nin – Ždrijac, u kontekstu socijalnog statusa. Temeljna pretpostavka jest da su osobe koje su pripadale različitim socijalnim grupama unutar zajednice uživale i različite životne prilike, što se onda odražavalo i na njihovo zdravlje i kvalitetu života, u smislu doživljene starosti. Socijalni status pokojnika određivao se pomoću arheološkog konteksta, odnosno karakteristika ukopa, a pod pretpostavkom da se socijalni status pokojnika odražavao i u načinu ukopa. Kriteriji koji su se pritom koristili su grobna arhitektura, te količina i vrsta grobnih priloga i nalaza. Kako bi se odredilo zdravstveno stanje pokojnika korištene su antropološke metode, što je uključivalo analize spola i starosti, te patologija koje ostavljaju traga na kostima. Za određivanje korelacija parametara koji određuju biološko zdravlje s parametrima koji određuju socijalni status korištene su multivarijatne log-linearne analize.

JOVANOVIĆ, Vladan, povjesničar
Edo Marković (1885. - 1939.) [Elektronička građa] : prilog za biografiju / Vladan Jovanović.
Bibliografske bilješke uz tekst ; bibliografija: str. 157-161. - Sažetak ; Summary. - U radu se na temelju arhivske građe, tiska, historiografske i memoarske literature rekonstruiraju biografski detalji iz života Ede Markovića, agronoma, bankara, javnoga radnika, člana Narodnoga vijeća Slovenaca, Hrvata i Srba te rotarijanskoga aktivista i generalnoga direktora državnoga monopolskog poduzeća za otkup i izvoz poljoprivrednih proizvoda. Posebna pozornost posvećena je „beogradskoj fazi” njegova života, profesionalnom angažmanu, međunarodnim aktivnostima i mjestu u poslovnim i političkim krugovima Kraljevine Jugoslavije te mogućim motivima njegova ubojstva, koje je počinila jugoslavenska policija 1939., a u tadašnjoj javnosti predstavljeno je kao „nesretan slučaj”. - Using archival data, press articles, and historiographical and memoir literature, this paper reconstructs biographical details from the life of Edo Marković, agronomist, civil servant, member of the National Council of Slovenes, Croats, and Serbs, Rotary Club activist, and general manager of the state monopoly company for the purchase and export of agricultural produce. The life philosophy of Edo Marković, which could be described in brief as opposition to inertia and authority, led him from his early childhood into temptations, which he overcame by following his intuition. They included identity dilemmas, education, political experimentation, and a principled determination to ‘serve the homeland, not the government’. Thanks to the organisational skills he displayed during World War I, his later banking career, the international reputation he enjoyed in the highest Freemason and Rotary circles, the crown of which was his position in the League of Nations, he acted more like an expert than a politician. Even though he was a member of several political organisations, he continued to adhere to the ideology of his old company, grown from the Croatian-Serbian Coalition. His Rotary enthusiasm outweighed the dashed hopes about the future of the Yugoslav state, and contributed to a sort of internal escapism and turn towards international activism. The affinity of Marković’s children for left-wing ideas, despite their material status, was certainly fostered by the opinions of their father, who afforded them a comprehensive education, thus allowing them to independently form their views on how the Russian Revolution went astray, the consequences of the Nazi rise to power, and the characteristics of Anglo-Saxon civilisation.

TAHRAOUI, Hichem
Prediction of the bicarbonate amount in drinking water in the region of Médéa using artificial neural network modelling [Elektronička građa] / Hichem Tahraoui, Abd Elmouneïm Belhadj, Adhya-Eddine Hamitouche. - Graf. prikazi.
Bibliografija: 30 jed. - Summary ; Sažetak. - The region of Médéa (Algeria) located in an agricultural site requires a large amount of drinking water. For this purpose, the water analyses in question are imperative. To examine the evolution of the drinking water quality in this region, firstly, an experimental protocol was done in order to obtain a dataset by taking into account several physicochemical parameters. Secondly, the obtained data set was divided into two parts to form the artificial neural network, where 70 % of the data set was used for training, and the remaining 30 % was also divided into two equal parts: one for testing and the other for validation of the model. The intelligent model obtained was evaluated as a function of the correlation coefficient nearest to 1 and lowest mean square error (RMSE). A set of 84 data points were used in this study. Eighteen parameters in the input layer, five neurons in the hidden layer, and one parameter in the output layer were used for the ANN modelling. Levenberg Marquardt learning (LM) algorithm, logarithmic sigmoid, and linear transfer function were used, respectively, for the hidden and the output layers. The results obtained during the present study showed a correlation coefficient of R = 0.99276 with root mean square error RMSE = 11.52613 mg dm–3. These results show that obtained ANN model gave far better and more significant results. It is obviously more accurate since its relative error is small with a correlation coefficient close to unity. Finally, it can be concluded that obtained model can effectively predict the rate of soluble bicarbonate in drinking water in the Médéa region. - Regija Médéa (Alžir) smještena na poljoprivrednom zemljištu zahtijeva veliku količinu pitke vode. U tu svrhu, analiza vode je od iznimne važnosti Da bi se ispitao razvoj kvalitete pitke vode u toj regiji, najprije je napravljen eksperimentalni protokol kako bi se dobio skup podataka uzimajući u obzir nekoliko fizikalno-kemijskih parametara. Zatim je dobiveni skup podataka podijeljen na dva dijela kako bi se stvorila umjetna neuronska mreža, gdje je 70 % skupova podataka upotrijebljeno za trening, a preostalih 30 % dodatno je podijeljeno na dva jednaka dijela: jedan za testiranje, a drugi za validaciju modela. Dobiveni inteligentni model procijenjen je kao funkcija koeficijenta korelacije najbližeg 1 i najnižeg korijena srednje kvadratne pogreške (RMSE). U ovom istraživanju upotrijebljen je skup od 84 podatkovnih točaka. Za modeliranje ANN-a upotrijebljeno je osamnaest parametara u ulaznom sloju, pet neurona u skrivenom sloju i jedan parametar u izlaznom sloju. Za skriveni i izlazni sloj upotrijebljeni su algoritam učenja Levenberg Marquardt (LM), logaritamski sigmoid i funkcija linearnog prijenosa. Rezultati dobiveni tijekom ovog istraživanja pokazali su koeficijent korelacije R = 0,99276 s korijenom srednje kvadratne pogreške RMSE = 11,52613 mg dm–3. Ti rezultati pokazuju da je dobiveni model neuronske mreže dao daleko bolje rezultate, jer je točniji a njegova relativna pogreška je mala s koeficijentom korelacije blizu jedinici. Konačno, zaključeno je da taj model može učinkovito predvidjeti brzinu topljivog bikarbonata u vodi za piće u regiji Médéa.

HEIMER, Željko
Uvod u istraživanje zmajske heraldike [Elektronička građa] / Željko Heimer. - Ilustr.
Bibliografske bilješke uz tekst ; bibliografija i izvori: str. 502-507. - Sažetak ; Summary. - Zmajska heraldika obuhvaća grbove i druge heraldičke oznake Družbe „Braća Hrvatskoga Zmaja” te zmajske grbove kao osobne znakove članova Družbe. Družba je tradicionalno hrvatsko svjetovno bratstvo i kulturna udruga koja čuva i obnavlja hrvatsku kulturnu baštinu i promiče identitet i postignuća hrvatske kulture, osnovana 1905. godine. Od osnivanja do danas Družba dodjeljuje svojim članovima osobne zmajske grbove u skladu s propisanim heraldičkim normama i pod stručnim nadzorom Zmajskoga heraldičkog ureda Družbe, čime se odlikuje kao jedno od tri područja žive heraldike u Hrvatskoj (uz municipalnu i crkvenu). Rad pozicionira zmajsku heraldiku u hrvatskoj heraldičkoj baštini, prikazuje njezin razvoj, djelovanje heraldičara i drugih koji su ju oblikovali, tipizira zmajske grbove prema vanjskim obilježjima oblikovanja u kronološki slijedne, jasno razgraničene tipove: četiri tipa do zabrane rada Družbe 1946. i četiri nakon njezine obnove 1990. godine. Kao prvo istraživanje ovoga materijala, ovaj rad otvara pitanja i postavlja teze na koje će se moći odgovoriti tek daljnjim istraživanjem. - Draconic heraldry is a term applied to coats of arms and other heraldic insignia of the ‘Brotherhood of the Croatian Dragon’ Society and the draconic coats of arms as personal symbols of the Society’s members. The Society, established in 1905, is a cultural association that strives to preserve and renew Croatian cultural heritage and promote the identity and achievements of Croatian culture. From its establishment until today, the Society has granted its members personal coats of arms in accordance with prescribed heraldic standards and under the professional supervision of the Draconic Heraldic Office, thus being one of three realms of living heraldry in Croatia (the other two being municipal and ecclesiastic heraldry). The paper positions draconic heraldry within the Croatian heraldic heritage, and presents its development and the activities of heraldists and other participants in its shaping. Prior to the ban of the Society in 1946 by the Communist regime, the heraldic office was implemented through the work of Emilij Laszowski, a co-founder of the Society and renowned heraldic expert, who hired a distinguished artist, Vjera Bojničić Zamola, to produce coats of arms under his guidance. Together they produced over 200 draconic coats of arms (and recreated some hundred historical Croatian noble coats of arms), today mostly preserved in the Native Collection in Ozalj. The ‘Genealogy’ of the Society, painted by Stjepan Kukec for its 35th anniversary, includes over a thousand of its members, among which more than 800 are presented with individual draconic coats of arms. After the renewal of the Society in 1990, the office was first led by Milovan Petković, who re-established the tradition and established cooperation with heraldic experts and artists. During his leadership and mostly with the help of Maja Bejdić as expert adviser and Mladen Stojić as graphical artist, some fifty draconic coats of arms were designed for Society members.

LIS, Tomasz Jacek
Službenici u Bosni i Hercegovini 1878. - 1918. [Elektronička građa] / Tomasz Jacek Lis ; preveli Tomasz Jacek Lis i Duje Jerković. - Graf. prikazi.
Bibliografske bilješke uz tekst ; bibliografija: str. 650-655. - Sažetak ; Summary. - U radu se analizira austrougarska civilna uprava u Bosni i Hercegovini od 1878. do 1918. godine. Ipak, nije riječ o instituciji nego o službenicima, često strancima, koji su ondje radili. Činovnici višega i nižega reda bili su odgovorni za provođenje svih odluka koje su donijeli političari u Beču ili Sarajevu. Oni su bili mostovi koji su spajali stanovnike Bosne i Hercegovine sa Zemaljskom vladom. U članku će se razmatrati njihov položaj u zemlji te njihov rad, ali i svakodnevni život jer su oni bili nova elita koja je modernizirala Bosnu i Hercegovinu na prijelazu iz XIX. u XX. stoljeće. - In my article, I would like to present the development of the civil administration in Bosnia and Herzegovina in the late 19th and early 20th century. This interesting issue is seldom examined in historiography. One can often read opinions that the Austro-Hungarian officials in Bosnia and Herzegovina were similar to the French or British colonial administration in African or Asian countries. On the other hand, Yugoslav, or sometimes post-Yugoslav, historians assert that Austro-Hungarian officials were the tools of a repressive policy. My goal is to carefully analyse this problem using archival sources from Bosnia, Poland, and Austria. Research reveals that said officials were not only of Austrian and Hungarian nationality, but there were also many Slavs among them. I shall also examine the cultural and social contribution of the new elite, which was composed of these officials.

RIMAN, Barbara
Slovenski prognanici u Nezavisnoj Državi Hrvatskoj [Elektronička građa] / Barbara Riman, Filip Škiljan.
Bibliografske bilješke uz tekst ; bibliografija: str. 894-897. - Sažetak ; Summary. - Problematika prognanoga slovenskog stanovništva s prostora koji je tijekom Drugoga svjetskog rata okupirao Treći Reich prisutna je u hrvatskoj, slovenskoj i srpskoj povijesti, ali je prije svega povezana s iseljavanjem i progonom drugoga (u prvom redu srpskoga) etničkog stanovništva. Ta etapa slovenske povijesti u Hrvatskoj nije dovoljno poznata široj javnosti. Upravo stoga radom se želi upozoriti na veliki broj Slovenaca koji su Drugi svjetski rat preživjeli na prostoru Hrvatske i Bosne i Hercegovine, odnosno tadašnje Nezavisne Države Hrvatske, koja je imala drugačije granice od današnje Hrvatske i Bosne i Hercegovine. U dosad objavljenim radovima o progonu slovenskoga stanovništva u Hrvatsku i Bosnu i Hercegovinu često se zaboravlja na dodatni kulturni šok koji su prognanici doživjeli. Osim opisa djelovanja legalnih institucija koje su bile zadužene za skrb o prognanom slovenskom stanovništvu, u radu su predstavljeni pojedinačni slučajevi iz kojih je vidljiva teška situacija i problemi s kojima su se suočavali stanovnici prognani iz slovenskih krajeva. - The problem of the expelled Slovene population from the areas occupied by the Third Reich during World War II is present in Croatian, Slovene, and Serbian history, but is primarily linked to the emigration and expelling of the population of other ethnicities (mostly Serbian). This phase of Slovene history is not well-known to the broader public in Croatia. Therefore, the aim of this paper is to highlight the large number of Slovenes who survived World War II on the territory of Croatia and Bosnia and Herzegovina, i.e. then the territory of the Independent State of Croatia, which had different borders than Croatia and Bosnia and Herzegovina today. Papers on the topic of the Slovene population displaced to Croatia and Bosnia and Herzegovina often do not consider the cultural shock that the displaced persons suffered. Apart from describing the activities of the institutions that were legal and responsible for providing for the expelled Slovene population, this paper also presents individual cases that exemplify the difficult situation and problems faced by those expelled from Slovene lands.
