The aim of this research is to determine the differences in attitudes toward physical exercise of students of Academy of Dramatic Arts in Banja Luka and Academy of Performing Arts in Sarajevo, and their interests in certain sports and recreational activities. The study included a total of 59 students of Academy of Dramatic Arts in Banja Luka and Academy of Performing Arts in Sarajevo. Given the requirements in terms of physical ability and physical appearance that contemporary theater and film production has for future actors, we believe that physical exercise should be their daily needs. The results of research have confirmed our opinion and pointed to a satisfactory level of physical activity of drama students. There was no significant difference in the attitudes of students toward physical exercise in relation to gender and place of study. The research results are encouraging, showing the awareness of students on the importance of practicing physical exercise in terms of improving the quality of life, as well as work and artistic creativity.

The subject of research in this paper is the planning of urban mobility development in the narrow part of Sarajevo using a model based on the growth matrix. The hypothesis of this research is: Based on the analysis of supply and demand of the city traffic system, good practices in sustainable urban mobility and existing strategies and development plans, a model for managing the whole planning process of sustainable urban mobility of the city traffic system in Sarajevo by 2026 can be proposed.In accordance with the experience of Europe’s main urban mobility observatory (Eltis) and sustainable urban mobility plans (SUMPs), the key elements are defined. The next step, after defining the elements of urban mobility, is to carry out the quantification of elements for 2016. Thereafter, there is a concise explanation of the growth matrix and model of managing the urban mobility planning process is created. In the research results, direct and indirect growth rates were elaborated and analyzed, i.e. the individual and synergic effects of the model. Finally, the synthesis of the research results was presented.

Chronic kidney disease is a progressive and irreversible loss of the kidney function. Besides physical and treatment complications for chronic kidney disease, kidney patients also suffer a number of psychological problems, among which depression and anxiety are very common. This all, not only make chronic kidney patients’, already difficult life, more difficult, but also further more vulnerable and at risk for earlier death. This study aimed to measure the level of anxiety and depression of chronic kidney disease patients have been measured and compared with the scores of healthy participants. Since hemodialysis is the most common treatment method for CKD, 60 haemodialysis patients at Inegol hospital in Turkey and 60 people from general healthy population (N=120) were conveniently chosen to participate in this study. Following literature review indicating possible psychological outcomes of chronic kidney failure and haemodialysis, depression and anxiety level among CKD patients and healthy cohort group was measured. Depression and anxiety levels were investigated using Beck Depression Inventory II and The State-Trait Anxiety Inventory were used (Turkish versions). Study results indicate, when compared to healthy cohorts (M=12.66, s.d. 5.7), CKD patients scored higher on depression scale (M=18.5, s.d. 7.3) as well as higher level of anxiety (M=40.76, s.d.10.7) when compared with healthy population (M=32.40, s.d. 7.8). Results of this study, next to important scientific contribution, indicate importance and the need for professional help psychological support for chronic kidney disease patients in order to diminish psychological impact of facing chronic illness.

The interdependence of corporate governance and organizational culture has always existed. Corporate governance is present in large organizations, which we call joint stock companies in BiH. The organization’s workflow, dividend payments, and day-to-day operations are monitored by people in charge of corporate governance. On the other hand, within each organization, and so on the corporations, a certain organizational culture is introduced, which is specific, and it is essentially known only by employees of a certain company. How much the real impact of organizational culture on corporate governance in BiH companies will be seen in the paper that follows. Corporative management is a form of governance that is characteristical for corporations, or for joint stock companies. Corporate governance, as a set of mechanisms by one corporation, grows and develops on the market, is of fundamental importance to developed countries of the world (United States - US, United Kingdom - UK, Germany, Canada, France and Japan). In the case of lower organizational forms of companies, capital owners often also make their management-management structure. The corporation represents such an organizational form of companies where there is a large number of capital owners whose ability to manage such an entity is insufficient, so they are required to engage professionally competent experts outside the business community (managers) to which they delegate the right to manage and manage. Organizational culture is a special form of culture that includes certain customs, attitudes, values, traditions and rituals. Organizational culture encompasses a system of ideas and concepts, customs, traditions, procedures and habits for acting in special macroeconomics. Organizational culture is a set of values, norms and beliefs.

Dynamical systems are no strangers in wireless communications. Our story will necessarily involve chaos, but not in the terms in which secure chaotic communications have introduced it: we will look for the chaos, complexity, and dynamics that already exist in everyday wireless communications.

We present a novel way of considering in-network computing (INC), using ideas from statistical mechanics. We model the execution of a distributed computation with graphs called functional topologies, which allows us to provide a formal definition for degeneracy and redundancy in the context of INC. Degeneracy for INC is defined as the structural multiplicity of possible options available within the network to perform the same function with a given macroscopic property (e.g., delay). Two degenerate structures can partially overlap. Redundancy, on the other hand, does not allow overlapping between the functional graphs. We present an efficient algorithm to determine all these multiple options and compute both degeneracy and redundancy. Our results show that by exploiting the set of possible degenerate alternatives, we can significantly improve the successful computation rate of a symmetric function, while still being able to satisfy requirements such as delay or energy consumption.

An increasing number of emerging applications, e.g., internet of things, vehicular communications, augmented reality, and the growing complexity due to the interoperability requirements of these systems, lead to the need to change the tools used for the modeling and analysis of those networks. Agent-Based Modeling (ABM) as a bottom-up modeling approach considers a network of autonomous agents interacting with each other, and therefore represents an ideal framework to comprehend the interactions of heterogeneous nodes in a complex environment. Here, we investigate the suitability of ABM to model the communication aspects of a road traffic management system, as an example of an Internet of Things (IoT) network. We model, analyze and compare various Medium Access Control (MAC) layer protocols for two different scenarios, namely uncoordinated and coordinated. Besides, we model the scheduling mechanisms for the coordinated scenario as a high level MAC protocol by using three different approaches: Centralized Decision Maker, DESYNC and decentralized learning MAC (L-MAC). The results clearly show the importance of coordination between multiple decision makers in order to improve the accuracy of information and spectrum utilization of the system.

This article focuses on the former war refugees, who (partly) returned to their homeland Bosnia and Herzegovina and became significant investors in their local communities. We are particularly interested in their experiences with manoeuvring between different countries and institutional environments, as these refugee entrepreneurs are running their businesses simultaneously in developed European economies (Switzerland and Sweden) and in their home country. Although the two companies run by the former refugees described in the article are located in the areas that remain divided along the ethnic lines caused by the war (Srebrenica and Banja Luka), we find that the post-war returnees’ businesses are ethnically tolerant and inclusive, sending a powerful message to the formal institutions, which often act in the opposite way.

Aims: The purpose of this study was to determine (a) the ability of serial high-sensitivity cardiac troponin T measurements to rule out acute myocardial infarction and (b) the ability of a single high baseline high-sensitivity cardiac troponin T measurement to rule in acute myocardial infarction in patients presenting to the emergency department with acute chest pain. Methods and results: Embase, Medline, Cochrane, Web of Science and Google scholar were searched for prospective cohort studies that evaluated parameters of diagnostic accuracy of serial high-sensitivity cardiac troponin T to rule out acute myocardial infarction and a single baseline high-sensitivity cardiac troponin T value>50 ng/l to rule in acute myocardial infarction. The search yielded 21 studies for the systematic review, of which 14 were included in the meta-analysis, with a total of 11,929 patients and an overall prevalence of acute myocardial infarction of 13.0%. For rule-out, six studies presented the sensitivity of serial measurements <14 ng/l. This cut-off classified 60.1% of patients as rule-out and the summary sensitivity was 96.7% (95% confidence interval: 92.3–99.3). Three studies presented the sensitivity of a one-hour algorithm with a baseline high-sensitivity cardiac troponin T value<12 ng/l and delta 1 hour <3 ng/l. This algorithm classified 60.2% of patients as rule-out and the summary sensitivity was 98.9% (96.4–100). For rule-in, six studies reported the specificity of baseline high-sensitivity cardiac troponin T value>50 ng/l. The summary specificity was 94.6% (91.5–97.1). Conclusion: Serial high-sensitivity cardiac troponin T measurement strategies to rule out acute myocardial infarction perform well, and a single baseline high-sensitivity cardiac troponin T value>50 ng/l to rule in acute myocardial infarction has a high specificity.

Fistulas between the gastrointestinal tract and bony structures of the pelvis are an extremely rare complication resulting from hip arthroplasty, whether primary or revisional. Only 15 cases were described in the English language literature containing this association. The predisposing factors described are Crohn’s disease, acute diverticulitis, use of corticosteroids and radiotherapy for malignant disease in the pelvis. In addition, it is related to the high morbidity and mortality rate due to late diagnosis, a fact that leads the patient to sepsis. We will describe a case of a male patient, without the risk factors described above, that developed a fistula between the sigmoid colon and the acetabulum after the second revision surgery of hip prosthesis. The patient had a good evolution due to early diagnosis and intervention.

Effective ventilation in general hospital wards is important for controlling the transmission of airborne infectious agents that may cause respiratory diseases. This study investigates the potential of protected occupied zone ventilation (POV) to reduce the risk of cross-infection in hospital isolation wards. Two life-size breathing thermal manikins were used to simulate an infected patient lying in a bed and a sitting, receiving health care worker. N2O was used as a tracer gas to simulate the droplet nuclei exhaled by patients. The contaminant exposure index ε e x p was used to assess the risk of cross-infection for different configurations of the supply velocity, the patient’s lying position and the exhaust openings. The contaminant exposure index ( ε e x p ) shows that the ventilation strategy is effective, but this is also highly dependent on the supply velocity and the location of the exhaust relative to the patient’s breathing zone. The patient’s posterior position does not affect the personal exposure of the receiving patient. Compared to traditional ventilation systems, the POV system can reduce the risk of cross-infection in hospital isolation rooms. The full potential of a POV system can be achieved in an isolation ward where movement between the infected and protected zones is restricted or prohibited.
