Background: The book “An Impossible Decision - the Life Interrupted by Uncertainty”has been published by Avicena Publisher in Sarajevo, Bosnia and Herzegovina in 2023 - ISBN: 978-9958-720-76-5. Objective: The aim of this article is to analize what is the most rational and ethical way to treat people facing life-and-death decisions and how do we exactly communicate these inevitable uncertainties that all of us will sooner or later face? Methods: Author of the book shows real-life relevance to patients often left alone to make these difficult decisions. Using the techniques of medical dramaturgy, this text brilliantly bridges science. Results and Discussion: The author of the book explained and proposed how to educate the public on how medical advances are made and how inferences and evidence are generated and appraised - in the best tradition of evidence-based medicine while highlighting uncertainties and inevitable trade-offs that accompany science, policies, and personal choices in the attempt to arrive at most satisfactory decisions. In addition to the general public, this play’s important audiences are students and faculty in humanities disciplines and medical schools. These students are required to read many dense scientific, philosophical, and technical writings (many of which are referenced/annotated in the footnotes in the play). The play provides an exceptional teaching tool, which includes over 35 theoretical concepts to show how they can be applied to decisions relevant to all of us and what shared decision- making entails. Conclusion: Author’s answer on the question “How to make the life and death medical decisions?” coul’d and shoul’d be: The method of using a playwright and Socrates dialogue format to connect the science of uncertainty with personal humanity decision will be appropriate. It will be important and quiet usefull for phisicians and, also, patients in healthcare practice, as joined decision makers.

Physical activity is important for the physical and mental health of almost everyone. Nordic walking is a physical activity in which participants use specially designed poles while walking, while the term jogging implies light running at speeds less than 10 km/h. PURPOSE: The aim of this research is to monitor the load intensity in real conditions, using a heart rate monitor Team Polar System, during nordic walking and jogging and comparing possible differences in heart rate responses after the fifth minute of activity, at an average speed of 7.5km/h. METHODS: The assessment of heart rate responses for this research was conducted on the 30 male students, at 2 separate days. RESULTS: The results of the variables used in this study show statistically significant differences at the level of significance p=.000. From the mean value results (M) it is obvious that the respondents achieved higher results of heart rate responses during nordic walking compared to the identical tests applied during jogging. CONCLUSION: The results of this study indicate that both Nordic walking and jogging are beneficial but Nordic walking contributes more in achieving higher body loads resulting in increased oxygen consumption and thus calories Key words: load intensity, heart rate, nordic walking, jogging

Balanced simplicial complexes are important objects in combinatorics and commutative algebra. A d -dimensional simplicial complex is balanced if its vertices can be coloured into d +1 colors, so there is no monochromatic edge. In this article, we establish two results concerning balanced simplicial complexes assigned to tilings of m × n board in a plane and a torus by I p -omino tile

Abstract The main aim of this study is to explore the mediating effect of innovation in the relationship between human resource management (HRM) practices and organizational performance. HRM practices are observed through selective hiring, training, participative decision-making, and rewarding. Innovation is conceptualized over behavioral, product, process, and market innovation. The study relies upon the principles of social exchange theory and resource-based theory. Data were collected from 408 managers in an emerging economy context. The proposed conceptual model is evaluated with structural equation modeling using Lisrel 8.8 and SPSS 22. Study findings suggest that innovation influences the relationship between selective hiring, training, and participative decision-making and organizational performance. However, no mediating effect of innovation was found in a relationship between rewarding and organizational business performances. Since human resources and innovation are among the leading sources for building competitive advantage for companies, the study findings contribute to HRM and innovation.

Abstract Banks and banking business are exposed to the influence of numerous risks, of which the importance of credit risk management stands out, because credit risk is the only risk that banks are obliged to measure, record in accounting and report. Banks monitor credit risk through the segmentation of the credit portfolio according to the level of risk. This paper is focused on research related to the management of the riskiest category of the credit portfolio, for which we will use the term special credit risk (SCR) in this paper.

Background and Objectives: We aimed to assess the effect of AST/ALT ratio on echocardiographic and cardiac magnetic resonance imaging (CMRI) parameters after COVID-19 patients recover. Materials and Methods: 87 patients with COVID-19 were included in the study. The patients were hospitalized with COVID-19 pneumonia, but the patients did not need intensive care unit follow-up or non-invasive mechanical ventilation support. After a discharge and two weeks following the positive swab test result, patients were considered eligible if they had any symptoms. Transthoracic echocardiography (TTE) was performed within 24 h prior to CMRI. The median value of AST/ALT ratio was found, and the study population was divided into two subgroups based on the median AST/ALT ratio value. The clinical features, blood test, TTE and CMRI results were compared between subgroups. Results: C-reactive protein, D-dimer and fibrinogen were found to be significantly higher in patients with high AST/ALT ratio. LVEF, TAPSE, S’, and FAC were significantly lower in patients with high AST/ALT ratio. LV-GLS were significantly lower in patients with high AST/ALT ratio. In CMRI, native T1 mapping signal, native T2 mapping signal and extracellular volume raised significantly in patients with high AST/ALT ratio. Right ventricle stroke volume and right ventricle ejection fraction were significantly lower in patients with high AST/ALT ratio, but right ventricle end systolic volume was significantly higher in patients with high AST/ALT ratio. Conclusion: High AST/ALT ratio is related to impaired right ventricular function parameters with CMRI and echocardiography after recovery from acute COVID-19. Assessment of AST/ALT ratio at hospital admission may be used to assess the risk of cardiac involvement in COVID-19 disease, and these patients may require closer follow-up during and after the course of COVID-19.

Flexibility is an important determinant of dynamic balance, but studies rarely examined the chronic effects of flexibility training on changes in balance capacity. This study aimed to determine the influence of different forms of flexibility exercises on dynamic balance in female professional football players. Participants were 30 female professional football players (age =19.0±4.1 years), divided into three groups dynamic stretching group (DSG; N=10, age =18.9±3.3 years), static stretching group (SSG; N=10, age =19.5±4.3 years) and control group (N=10, age =18.5±3.3 years). All groups participated in equal football training, while DSG and SSG performed additional flexibility training 3-times a week (10-15 min of duration) throughout the study course (16 weeks). Dynamic balance was measured by the Y-balance test (YBT), and ANOVA for repeated measurement was applied to identify the effects. Results evidenced the significant influence of both flexibility programs on dynamic balance. Both DSG and SSG were equally effective in the first part of the study (until the 8th week), but between the 8th and 16th study week, only DSG improved their balance capacity significantly. Static stretching should be applied in the first phases of flexibility training aiming at the improvement of dynamic balance, but in later phases, usage of dynamic stretching is suggested.

Abstract In this paper six heterobranch mollusc species are reported for the first time for Bosnia and Herzegovina: Berthellina edwardsi (Vayssiere, 1896), Felimida luteorosea (Rapp, 1827), Thuridilla hopei (Verany, 1853), Dendrodoris grandiflora (Rapp, 1827), Camachoaglaja africana (Pruvot-Fol, 1953) and Felimare villafranca (Risso, 1818). The study was conducted in October 2021 on Klek Peninsula and in Neum Bay (eastern Adriatic Sea, Bosnia and Herzegovina). This paper significantly extends the knowledge of the national marine heterobranch molluscs fauna, almost doubling the number of species known for the country, as only seven heterobranch species were reported for Bosnia and Herzegovina until now.

One of the key research directions to increase the capacity of new radio (NR) vehicle-to-everything (V2X) communication systems is extension of employed frequency bands from sub-6 GHz to millimeter wave (mmWave) range. To investigate different propagation effects between sub-6 GHz and mmWave bands in high-mobility scenarios, one needs to conduct channel measurements in both frequency bands. Using a suitable testbed setup to compare these two bands in a fair manner, we perform channel measurements at center frequencies of 2.55 GHz and 25.5 GHz, velocities of 50 km/h and 100 km/h, and at 126 different spatial positions. Furthermore, we conduct a comparative study of the multi-band propagation based on measurement results. We estimate the power delay profile (PDP) and the Doppler power spectral density (DSD) from a large set of measurements collected in a measurement campaign. Finally, we compare measured wireless channels at the two employed frequency bands in terms of root-mean-square (RMS) delay spread and RMS Doppler spread.

Acute kidney injury (AKI) is associated with an increased risk of progression to a severe form in every disease and, moreover, is associated with an increased mortality, and so it is also with coronavirus disease 2019 (COVID-19). AKI is a frequent complication in COVID-19 patients admitted to ICU for severe respiratory failure. ICU treatment itself indirectly could cause or exacerbate renal damage, through suboptimal fluid management, drug toxicity, or low human resources. The aims of this study were to assess AKI prevalence, fluid balance and glomerular filtration rate as a predictor of outcome in COVID-19 patients treated in the intensive care unit. We retrospectively analysed all adult patients admitted to the ICU at a regional hospital in northern Bavaria, from 1st March to 31st December 2020. Clinical data and laboratory results were retrospectively retrieved from the hospital information system and electronic case files. According to the severity of AKI based on the KDIGO criteria, and laboratory values were followed on the first 7 days on the ICU. In total 320 patients patients were included in the study. Level of significance was set to p<0.05. The mean age was 65 ± 19 years, 135 (42%) patients were females, 185 (58%) were males. Median length of ICU stay was 7 (2-13 days) in females, and 8 days (4- to 21 days) in males. At the ICU, 177 patients needed some form of ventilation, from which 109 (needed Invasive mechanical ventilation). During ICU stay, 81 patients have died, with fatality rate of 25%. Patients with AKI (n=48, 15%) at the admission to the ICU, had 2.1 times higher risk of death at the ICU than patients without AKI. There was a statistically significant difference in ICU survival based on a glomerular filtration rate, fluid balance, CRP and leukocyte values, F=1.957, p=0.026; Wilk's Λ=0.724, partial η2 = 0.276 Acute kidney injury is common in coronavirus disease 2019, and it is associated with poor clinical outcomes. Even first couple of days at the ICU could point to the outcome, with markers of inflammation, glomerular filtration rate, and fluid balance being most valuable variables.
