Hammer throw is motor-wise an extremely complex throwing discipline with the manifestation of several different forces that impede the rotational movement of the device and the thrower in the projected sagittal plane. Kinematic parameters are one of the segments when analyzing athletic disciplines, including hammer throw. This study aims to determine spatial and time differences of kinematic parameters between male and female hammer throw finalists at the 2017 Athletics World Cup in London. The study was conducted on a sample of 24 finalists of the 2017 Athletics World Cup in London, with the aim to analyze the differences in kinematic parameters between male and female hammer throwers. The results were acquired by applying the Independent Sample t-Test. It has confirmed the differences in most of the parameters, except those regarding ejection height (T=2,992; p<0,009), where it established statistically significant discrepancies between male and female finalists. On average, the male finalists threw a hammer from a height of 1,74±0,13m, and the female finalists from 1,54±0,17m. Based on the obtained results of kinematic parameters, it can be concluded that quantitative and qualitative differences in the measured kinematic parameters of the finalists in London are evident, but that statistically significant differences are recorded only in the ejection hight of the device.

The purpose of this study aimed to look at assessing the effects of aerobic exercise on body composition of overweight female aging 22-27 years.A sample of n=30 (thirty) overweight female aging 22-27 years in District Tonsa (Punjab), Pakistan were included as subject. A four (04) week exercise protocol was prepared and used among females of the experimental group. The experimental group was subjected to measure the anthropometric as well as 3- site skin fold measurements. The data regarding pre and post-test of both groups-control and experimental were carefully recorded and entered into the computer for analyses. For this purpose, both descriptive (mean and standard deviation) and inferential statistics (Independent Samples t-Test and Paired Samples t-Test) were used for analyzing the data. The analyzed data established that the mean score of (EG) in pre and post-test were found as 28.66 and 23.5. The t-value of the table is 5.022 and P-value is 0.001 which is lower than the significant level (P<0.05). Therefore, it is concluded that the difference between Pre and Post-test of Control Group has shown the significant effects of aerobic exercises on body fat percentage of overweight females. According to the analyzed data the mean value of Post-tests regarding body fat percentage of Control Group were 28.89 and Experimental Group was 23.5. The P-value 0.002 and t-value -987 in the table depict the significant statistical difference between the two means of Control and Experimental Group in Body Mass Index (P<0.05).The results of the study indicated that the four weeks’ aerobic exercise protocol has a significant effect on overweight females in the perspective of decreasing their body fat percentage. Based on the findings, the researcher recommended that more and more involved in physical activity and exercise among female folk may be ensured.

Cilj ove pregledne studije bio je da ukaže na primenu elektromiografa u fudbalu. Za pretraživanje literature korišćene su sledeće elektronske baze podataka: Google Scholar, PubMed, Medline, Mendeley u periodu od 2005. do 2019. godine. Nakon procedure selekcije radova u odnosu na odgovarajuće kriterijume, odabrano je 20 studija koje odgovaraju potrebama ovog sistematskog preglednog istraživanja. Mišići koji su najviše bili ispitivani su: m.musculus quadriceps, m.biceps femoris, m.gastrocnemius, m.tibalis anterior i m. gluteus maximus. Pregledom je uočen prilično heterogen izbor tema kada je u pitanju uloga EMG u fudbalu, pa su i njihovi ostvareni rezultati grupisani prema određenim karakteristikama. S tim u vezi rezultati su razvrstani prema sledećim temama: akutni efekti specifične fudbalske aktivnosti, uticaj fudbalskog treninga snage, trening udaraca po lopti nogom, rezultati u odnosu na polne razlike i ostale teme koje nije bilo moguće razvrstati u pomenute grupe. Sumiranjem dosadašnjih rezultata stiče se uvid u višestruku primenu EMG u fudbalu sa ciljem što kvalitetnije analize neuro-mišićne aktivacije.

The aim of this systematic review was to indicate and discuss the use of electromyogram in football. For the literature review, following electronic databases were used: Google School, PubMed, Medline and Mendeley for the period from 2005. to 2019. 20 papers were selected for this systematic review based on the established criteria. These studies focused the most on researching the following muscles: m.musculus quadriceps, m.biceps femoris, m.gastrocnemius, m.tibalis anterior and m. gluteus maximus. The review has determined quite a heterogenic choice of topics when it comes to the use of the electromyogram (herein after referred to as: EMG) in football, so the obtained results were grouped based on the similar characteristics. Therefore, the results were categorized according to the following topics: acute effects of the specific football activity, impact of the football strength training, training of kicking on the ball, results based on the difference in sexes, while the rest of the results were sorted in the joint group. Summarizing of the obtained results provides the insight in the multiple possibility for use of EMG in football in order to develop high quality analysis of the neuro-muscle activation of a certain muscle regions of the football players.

Fault location is one of the most common aspects of power system analysis and protection. In order to maintain system's stability and avoid long lasting blackouts, it is important to localize a fault in shortest possible time. This paper analyzes already published impedance-based fault location methods and suggests new algorithm based on orthogonal components. Proposed method is applied on Simulink created three phase model, considering various system specifications including different fault resistance values, having more than one fault on a line at different locations, grounded and ungrounded generators effects, sampling rate changes, line length effects, etc. The results are indicating good accuracy of the algorithm itself.

This paper focuses on closed loop operational mode of Volt-VAr control (VVC) algorithm, as well as the power flow (PF) methods that can successfully be used to implement VVC. Two methods to implement efficient PF are Newton-Raphson approach and current iteration approach. The paper compares both approaches to find the one most suitable for the implementation of closed loop VVC algorithm.

Hyperuricemia is a potential marker of cardiovascular diseases, and its relation to hypertension and arteriosclerosis, as well as the outcomes of certain cardiovascular events, is interesting. The research was carried out a sample of 50 subjects of both sexes, who were either on allopurinol or febuxostat treatment. Effects of allopurinol and febuxostat on concentrations of uric acid and some lipid fractions (total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol) were observed in 25 subjects on allopurinol treatment, and in 25 subjects on febuxostat treatment, who were chosen by defined criteria, with each patient serving as his or her control. The total observation period was six months and the cut was made after the first three Original Research Article Ziga Smajic et al.; JPRI, 32(35): 44-54, 2020; Article no.JPRI.63434 45 months and at the end of the research. Evaluating the effectiveness of allopurinol in subjects with hyperuricemia, it was established that concentrations of uric acid decreased by 126.28±20.36 μmol/L, at the end of the research, compared to the initial concentration. In subjects who used febuxostat, at the end of the research, concentrations of uric acid decreased by 252.80±94.17 μmol/L, compared to the initial concentration. Evaluating the effectiveness of febuxostat on concentrations of lipid fractions, a statistically significant increase of 0.17±0.02 mmol/L in concentrations of HDL and a statistically significant decrease of 0.37±0.14 mmol/L in concentrations of LDL were noted. Subjects with gout treated with allopurinol had significantly lower average concentrations of cholesterol compared to subjects with gout and metabolic syndrome (p=0.001). Subjects with gout and metabolic syndrome had significantly higher concentrations of LDL at the beginning and the end of the research, regardless of therapy (p=0.045;p=0.049, respectively). Both drugs showed effectiveness in the treatment of hyperuricemia, and a certain effect on concentrations of lipid fractions.

The article deals with the contemporary labor migrations from Bosnia and Herzegovina to Slovenia and the other countries of European Union, specifically during the period of the COVID-19 pandemic On the basis of fieldwork among the participants in these migrations, it seeks to identify the specifics of circumstances and situations that arose suddenly with the closure of political borders and the demands of social di-stancing In these circumstances, we supposed that labor migrants found themselves to be a particularly vulnerable group of population The case study has denied that this is completely true On the other hand, labor migrations from Bosnia and Herzegovina to Central, Western and North European and some non-European countries have been a continuous process for the last century and at least migration flows must be taken as a fact which directions, volumes and character are greatly influenced by labor market regulations in each individual EU member and other states Periodically, specific political and social situations also gain importance The COVID-19 pandemic has exactly such an impact © 2020, University of Ljubljana All rights reserved

The paper has two research goals. The first goal is to investigate the prevalence of certain techniques of strategic management accounting in large companies in Bosnia and Herzegovina (hereinafter BiH), while the second research goal is to analyze the dependence of the number of strategic management accounting techniques used and the degree of development of the cost system in the company. For the purposes of this research, we collected survey questionnaires from 110 large companies based in BiH. The results of the research show that the three most common techniques of strategic management accounting in large companies in BiH are: Quality Costing (52.73%), Strategic Pricing (51.82%) and Benchmarking (50.91%), while the least common techniques are: Life Cycle Costing (11.82%), Attribute Costing and Integrated Performance Management Systems (with 12.73% each), and Activity Based Costing/ Management (17.27%). One-way analysis of variance (ANOVA) tested the differences in the number of strategic management accounting techniques used and the level of development of the cost system in companies. Companies that applied on average two techniques of strategic management accounting belonged to the first level of development, those that applied on average four techniques belonged to the second level of development, while companies that have the third level of cost system development on average applied six techniques of strategic management accounting. There were no companies in the sample with the fourth and fifth level of development of the cost system.

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.
