The aim of this research is to determine the possession of predisposition for the success of doing business management in the sport. The study was conducted on a sample of 120 managers of sports clubs in Tuzla Canton and Brcko District. A sample of 20 variables is drawn from the survey “Do you have the potential to be a manager?”. Survey results showed that 31 respondents possess many skills and abilities that are required for a successful manager, 63 respondents have some of the skills and abilities to successfully manage, and 26 respondents do not possess adequate skills and the ability to successfully manage others.It is obvious that respondents who want to be successful managers need to pay attention to the managerial skills and techniques in which they feel the weakest.It is logical that different levels of management require different levels of given skills and knowledge. At lower levels of management the need for a higher level of technical knowledge is pronounced. The fact is that –top managers, in contrast to managers at lower levels of the organization, must have a high ability of conceptual thinking based on a high degree of creation and imagination. These are the qualities and skills that cannot be acquired through the educational process.

Vertex-frequency analysis of graph signals is a challenging topic for research and applications. Counterparts of the short-time Fourier transform, the wavelet transform, and the Rihaczek distribution have recently been introduced to the graph-signal analysis. In this letter, we have extended the energy distributions to a general reduced interference distributions class. It can improve the vertex-frequency representation of a graph signal while preserving the marginal properties. This class is related to the spectrogram of graph signals as well. Efficiency of the proposed representations is illustrated in examples.

This study was conducted on a sample of 40 senior and junior male and female karate fighters, chronological ages 18 to 27 from the Tuzla Canton, who are part of the regular training and competition process. The aim of this paper is to determine the differences in the motor reaction speed among the karate players with the same specializations but at different levels of competition, in conditions of fatigue induced by intense physical work in combination with complex visual signalization, which determines certain karate techniques. The study was conducted with the application of sophisticated technologies used in sport that enable the collection of data. The light stimuli was generated by the usage of the RIR 102 reaction meter and the quantitative valorization of the investigated parameters was carried out by a sophisticated kinematic analysis of the videos collected using two high-speed Casio Exilim EX-F1 digital cameras synchronized with the data from the Polar Team heart monitoring system. By processing and analyzing data, it was concluded that fatigue induced by situational conditions such as performing a series of strikes that simultaneously generate muscular, cognitive and sensory strain, produces negative effects on reaction time of the karate players. The intensity of limiting factors grows gradually in function of time, but is manifested differently in relation to the international and state level of competition.

Background: In this clinical pharmacological research, we dealt with the action of allopurinol on triglyceride levels in hyperuricemic patients.Methods: The study included 40 hyperuricemic patients, of both genders and different age groups, that were sorted by comorbid diagnoses in several subgroups. All patients were clinically treated in the period of three years both at UCC Sarajevo, and P.I. General Hospital "Abdulah Nakaš" Sarajevo. All clinical measurements were carried out using standard IFCC methods with the appropriate analysers.Results: The study was based on mean triglyceride levels before and after three and six months of treatment with allopurinol. It was found out that the mean triglyceride levels were not significantly different from the reference values prior to treatment (p = 0.846) and after three months of therapy (p=0.153). In contrast, after six months of treatment, triglyceride levels significantly increased compared to the reference values. In patients with a diagnosis of gout and metabolic syndrome, triglycerides were statistically significantly increased during the six months of observation. A statin group of patients showed a statistically significant increase in triglyceride levels after three months of therapy (p = 0.032), while, after six months their levels had decreased (p = 0.029). In patients with diabetes mellitus type II, triglycerides rose after three months of treatment (p = 0.039) and retained the same level after six months of observation.Conclusions: The analysis shows that the use of allopurinol has an effect on triglyceride levels in hyperuricemic patients.

Recent technological advances in single cell sequencing (SCS) provide high resolution data for studying intra-tumor heterogeneity and tumor evolution. Available computational methods for tumor phylogeny inference via SCS typically aim to identify the most likely perfect phylogeny tree satisfying infinite sites assumption (ISA). However limitations of SCS technologies such as frequent allele dropout or highly variable sequence coverage, commonly result in mutational call errors and prohibit a perfect phylogeny. In addition, ISA violations are commonly observed in tumor phylogenies due to the loss of heterozygosity, deletions and convergent evolution. In order to address such limitations, we, for the first time, introduce a new combinatorial formulation that integrates single cell sequencing data with matching bulk sequencing data, with the objective of minimizing a linear combination of (i) potential false negatives (due to e.g. allele dropout or variance in sequence coverage) and (ii) potential false positives (due to e.g. read errors) among mutation calls, as well as (iii) the number of mutations that violate ISA - to define the optimal sub-perfect phylogeny. Our formulation ensures that several lineage constraints imposed by the use of variant allele frequencies (VAFs, derived from bulk sequence data) are satisfied. We express our formulation both in the form of an integer linear program (ILP) and - for the first time in the context of tumor phylogeny reconstruction - a boolean constraint satisfaction problem (CSP) and solve them by leveraging state-of-the-art ILP/CSP solvers. The resulting method, which we name PhISCS, is the first to integrate SCS and bulk sequencing data under the finite sites model. Using several simulated and real SCS data sets, we demonstrate that PhISCS is not only more general but also more accurate than the alternative tumor phylogeny inference tools. PhISCS is very fast especially when its CSP based variant is used returns the optimal solution, except in rare instances for which it provides an optimality gap. PhISCS is available at https://github.com/haghshenas/PhISCS.

ABSTRACT Introduction: Evolocumab is fully human monoclonal antibody which binds to proprotein convertase subtilisin/kexin type 9 (PCSK9), and prevents its blocking effect on recycling of liver low-density lipoprotein (LDL) receptors. Areas covered: The aim of this review is to assess efficacy, safety, and cost-effectiveness of evolocumab in adult patients with high cardiovascular risk. Major research databases MEDLINE, EBSCO, and CENTRAL were systematically searched for relevant study reports. Expert commentary: Even when given in full doses, statins augmented with ezetimibe and cholesterol-binding resins could not reduce cholesterol baseline level for more than 66%, while evolocumab reduces cholesterol level for 75% or even more. Up to now, evolocumab showed good safety profile, and patents tolerate it very well. The abovementioned advantages of evolocumab made it almost ideal drug for hypercholesterolemia, and probably in the future the best drug for secondary prevention of major cardiovascular events. Evolocumab is borderline cost-effective for the treatment of patients with high cardiovascular risk in European countries, while in the U.S.A. it is under debate where the underlying assumption (risk of cardiovascular disease events) determine the true value.

The aim of this research was to determine the relations of fitness parameters and morphological characteristics of seven-year-old obese children. The sample of participants consisted of 103 obese children (63 girls and 40 boys), first grade students (mean age 7.04 years) of elementary schools in Nis. The following fitness parameters were measured: HR in load, VO2max (ml), HR in peace, bend forward - bend backward - throw test, hand taping, 20m dash with a standing start, Abalakov test and forward bend on the bench test. Morphological characteristics were determined by measuring 13 parameters of longitudinal and transversal dimensions of skeleton, volume and body mass, as well as subcutaneous fat tissue. Canonical correlation analysis was used to determine the relations between the set of variables representing fitness parameters and the set of variables of morphological characteristics. Based on the coefficients of canonical correlation analysis, it can be concluded that the spaces of morphological characteristics and fitness parameters are interconnected with two pairs of statistically significant canonical factors (p˂.05 and p˂.01). The general analysis of the relationships between the first pair of canonical factors suggests that subjects with higher circular dimensionalities of the body, accentuated adiposity and body mass tend to have poorer results in motoring tasks requiring body flexibility, explosive leg strength and running speed, and also have poorer results in the parameters of cardiorespiratory fitness. It can be concluded that obesity in young school age has negative implications on the fitness parameters in children, and therefore on their overall growth and development.

The aim of the research was to determine the effects of applied technical and tactical characteristics of table tennis players on their success in competitions. The representative sample consisted of 48 top senior table tennis players from Bosnia and Herzegovina, age 18 and 36, selected on the basis of a qualification tournament. The measuring instruments for this study included eight assessment tests for the table tennis players' technical and tactical characteristics and one test for assessing success in table tennis competitions. Technical and tactical characteristics of the participants were evaluated by five experts who analyzed the efficacy of technical and tactical characteristics of the players on a scale ranging from 1 to 5. The methods of processing the results included descriptive statistical procedures, the multiple correlation coefficient, the determinant coefficient and a multiple regression analysis. The results indicate that technical and tactical characteristics have a major impact on the player's performance and are essential for table tennis success. Based on the value of the regression coefficients and their significance, it may be concluded that the 5 variables statistically significantly contribute to the regression model are: the efficiency of the serve; the efficiency of preventing the attack of the opponent and preparation of the players’ own attack; confidence when attacking across the table; the efficiency in the active defence and the efficiency of movement during the game. In the hierarchy of significance, the most important variables are the serve efficiency and efficiency of preventing the attack of an opponent and preparation of the player's own attack. The efficiency of the serve allows an attacker to realize technical and tactical ideas and usually gain initiative in the game. By returning a serve we can prevent or at least make it harder for the opponent to attack again. A serve return can also allow us to take the initiative

Topological phases of matter that have an insulating bulk and robust gapless boundary states can exist both in static materials and when system parameters are changed periodically in time. In the latter case, the periodic driving can lead to so called ``anomalous'' topological phases. Here, the authors show that, in the newly introduced higher-order topological insulators, anomalous phases can exist even if the system is static, and provide an example of such behavior using a two-dimensional model with topological corner charges. This work opens up the possibility of studying anomalous phases without the inherent difficulties associated with time-periodic changes of a material, such as the risk that it will ``heat up'' due to the driving field and lose its topological features.
