Bosnia and Herzegovina is a country with a very high risk of floods, which is documented in Vulnerability assessment, where it is defined that "floods represent the greatest danger for community and its population". Due to climate changes in recent decades, floods have become one of the most serious forms of threat to the population and material assets. After signing the Stabilization and Association Agreement with the EU in 2008, BiH accepted obligation to harmonize its legislation with the EU acquis communautaire, which also includes water legislation. The complex constitutional arrangement and unfavorable socio-economic situation make it difficult to fulfill assumed obligations, as well as protection and rescue system normal functioning on state territory. This research subject is protection and rescue system analysis, assessment of the adequacy of existing measures and current flood risk management techniques in BiH through a comparative analysis with practice of flood risk management in the EU.

Like any crisis in the human world, the migrant crisis can be approached without more comprehensive interpretations and deeper understanding. Nevertheless, recognizing intuitions at the first observations of European and Balkan "migrant events" is prudent, and beyond prejudice and pre-understanding, to search for the causes of the crisis. The ongoing migrant crisis has highlighted the need to create and implement a multidisciplinary model of understanding the 21st-century conflict. Models used so far halved from mega authorial theories and political doctrines, such as various pro-globalization or anti-globalization approaches, transitional neoliberal formulas, the pattern of "new world order," or "clash of civilizations," clashes of religions and cultures, world system, post-imperialism, various postmodern theories, doctrines of so-called soft and hard power, they have proven to be incompliant to events and therefore insufficient for a complete understanding of the contradictions and contradictions of the modern world. Historically, the current migrant crisis has regained the importance of questioning the spatial dimensions of the European populist configuration. The current and previous migrant problems have reminded classical and contemporary geopolitical theories of the original understanding of this approach to social and political phenomena, long overdue by Rudolf Kjellen. In one of the earliest divisions of geopolitics, a deserved place was found by demo politics. The focused demo-political reflection gains importance in situations of growing demographic problems. While geopolitics primarily encompasses processes of changes in space and area, demo politics touch on politically conditioned processes in the population. In seemingly chaotic demo politics, it reaffirmed the importance of a critical geopolitical interpretation of migrant processes. Even among the pro-non Eurocrats, for various ideological reasons, extremely inclined to specific geopolitical ideas and arrangements, it strengthened the sense of continental spatiality, accompanied by the knowledge that geopolitics "after all" has returned to European and world relations. In addition to many crises that have befallen Europe, the return of geopolitics has been contributed by the disruption sustained by the migrant wave. The current migrant crisis is a causal-consequential crisis, which means that as an already emerging disorder, it causes many other diseases that would not be without its effect. Still, it is also caused by factors that have previously shaped it and may not be known enough until this moment. The driving and emergence of the migrant crisis have occurred in the past; its modern development encompasses the present, and, likely, the migrant crisis will be faced by Europe in the future. Hence, it is necessary to bear in mind the concrete historical dimension of the problem, which also contains specific chrono-political components. When something is not understood as before at one time, the development usually enables that if it is to be understood in the consequential time.

Nowadays, when operating in an unstable market, organizations in Bosnia and Herzegovina (BiH) are also facing a continuous outflow of qualified employees to the countries of the European Union. In order to properly respond to the challenges from the environment, the organizations in BiH are forced to take adequate measures so as to become competitive in the market, which may prove to be difficult if they do not retain skilled workforce. This paper attempts to show that by implementing appropriate human resource management (HRM) practices and policies, organizations in BiH can affect employee organizational commitment, which will result not only in market survival but also in increased competitiveness, as the experience of the organizations in the surrounding countries shows that human resources is what gives these companies a competitive advantage. The paper aimed at examining the impact of characteristics, organizational characteristics, and HRM practices focused on performance appraisal, job security, employee participation, and career planning on employee organizational commitment in BiH companies with more than 50 employees in four sectors. The empirical research was conducted on a sample of 128 companies. The results show that when it comes to employee organizational commitment, HRM practices and policies bear more importance than demographic and organizational characteristics and that there is a statistically significant positive impact of HRM practices and policies on employee organizational commitment.

Dysphagia, commonly referred to as abnormal swallowing, affects millions of people annually. If not diagnosed expeditiously, dysphagia can lead to more severe complications, such as pneumonia, nutritional deficiency, and dehydration. Bedside screening is the first step of dysphagia characterization and is usually based on pass/fail tests in which a nurse observes the patient performing water swallows to look for dysphagia overt signs such as coughing. Though quick and convenient, bedside screening only provides low-level judgment of impairment, lacks standardization, and suffers from subjectivity. Recently, high resolution cervical auscultation (HRCA) has been investigated as a less expensive and non-invasive method to diagnose dysphagia. It has shown strong preliminary evidence of its effectiveness in penetration-aspiration detection as well as multiple swallow kinematics. HRCA signals have traditionally been collected and investigated in conjunction with videofluoroscopy exams which are performed using barium boluses including thin liquid. An HRCA-based bedside screening is highly desirable to expedite the initial dysphagia diagnosis and overcome all the drawbacks of the current pass/fail screening tests. However, all research conducted for using HRCA in dysphagia is based on thin liquid barium boluses and thus not guaranteed to provide valid results for water boluses used in bedside screening. If HRCA signals show no significant differences between water and thin liquid barium boluses, then the same algorithms developed on thin liquid barium boluses used in diagnostic imaging studies, it can be then directly used with water boluses. This study investigates the similarities and differences between HRCA signals from thin liquid barium swallows compared to those signals from water swallows. Multiple features from the time, frequency, time-frequency, and information-theoretic domain were extracted from each type of swallow and a group of linear mixed models was tested to determine the significance of differences. Machine learning classifiers were fit to the data as well to determine if the swallowed material (thin liquid barium or water) can be correctly predicted from an unlabeled set of HRCA signals. The results demonstrated that there is no systematic difference between the HRCA signals of thin liquid barium swallows and water swallows. While no systematic difference was discovered, the evidence of complete conformity between HRCA signals of both materials was inconclusive. These results must be validated further to confirm conformity between the HRCA signals of thin liquid barium swallows and water swallows.

Fiber optics has revolutionized telecommunication with its superior bandwidth and distance it can span. For its use in IoT networks, some of the limiting factors are the high cost of new installations and the need to power the end device by electrical current. The installations are a part of long-term investments, and one can expect this to be an ever-smaller issue as more fibers are installed. Typically, the newly installed cables contain single-mode fibers. There are a lot of reports on transport of power over fiber, however, majority recommend using multi-mode fibers with a large core or double-clad fibers. In our approach, instead of increasing the core of the fiber, we focus on the possibility of shortening the working time of IoT devices, using the existing single-mode fiber for powering. Also, instead of an expensive PV (photo voltaic) cell with small dimensions and a high efficiency, we propose using the commercially available larger PV cells with an air gap between the end of the fiber and the cells. In accordance with our approach, we successfully conducted an experiment.

The purpose of this paper is to examine the current state of rural tourism in Republic of Srpska as well as to provide guidance and recommendations for the development of this form of tourism. The used model approach expert opinion and, on this occasion, the DEX method of multicriteria decision-making was used. With this model, an assessment of rural tourist capacities is carried out on a random sample of four tourist facilities. The reason for the results obtained in this way is that the observed facilities have adequately used the natural resources available to Republic of Srpska. In addition, recommendations and guidelines are given in order to further develop this type of tourism in Republic of Srpska. The presented model offers an innovative approach in the assessment of current and potential tourist facilities. For this reason, it should be used in future research.

Changes in the market, caused by globalization, have led to the fact that many companies needed to adapt their operations. In response to these changes, the concept of supply chain was developed to help companies from procurement to sales of products. This paper examines the effects of supply chains on competitiveness using the example of agro-food companies from the Republic of Croatia. The research was conducted through a questionnaire which included 188 agribusiness companies. The responses were systematized and statistically processed using descriptive statistics, correlation analysis and multivariate regression analysis. The results showed that the effects of supply chains play a major role in determining the competitiveness of agro-food companies. Therefore, it is necessary to improve the effects of the supply chain in these companies in order to improve competitiveness and achieve better results of these companies on the market.
