The aim of this research was to determine the structure of football through indicators of situational efficiency in world championship matches. The research sample consisted of 370 soccer players who played all 90 minutes of the Round of 16 matches of the three world soccer championships WC2010 (N = 124), WC2014 (N = 126) and WC2018 (N = 120). 30 variables of situational efficiency were used, which were taken from the official website of the World Football Federation (www.fifa.com). To determine the structure of football, we used factor analysis, the method of principal components with oblique direct oblimin transformation was used, and the Kaiser-Gutman criterion was used to determine the significance of the extracted factors. Analyzing the results, the explanation of the common variance was the highest at WC 2010 (83.52 %), followed by WC 2014 (81.97 %), and the lowest explained variance was at WC 2018 (76.30 %). In the structure of football at WC 2010 and WC 2014, 6 latent factors were singled out, and at WC 2018, 4 latent factors were singled out, which are differently saturated with situational indicators. We conclude that changes have occurred in the structure of football over a period of 8 years, which is shown by the number and structure of factors that have been fished out. The structure of football has changed in such a way that the number of factors has been reduced from 6 to 4, and the structure of isolated factors clearly defines modern football. Based on the results, the guidelines and standards on which football training should be based can be clearly determined, while using certain training tools, training stimuli and appropriate training loads in order to achieve a high level of physical preparation, a high level of technique in movement, a high rhythm of the game and tactical maturity of football players.

Sušenje mesa datira još iz doba Rimljana koji su u svojim sušnicama sušili razne vrste mesa koje su konzumirali moreplovci trgovci s juga, a vremenom je suho meso stiglo i u sjeverne evropske zemlje. Ipak, bitno je naglasiti da tu nije riječ o suhom goveđem mesu koje je tradicionalno za naše područje. Tradicija pravljenja suhog mesa u našoj zemlji je stara vijekovima, a neki proizvođači su i danas zadržali stari način pravljenja ovog proizvoda. Miris i okus suhog mesa se razlikuje od područja do područja pa tako zavisi od klime, nadmorske visine, načina ishrane, vrste goveda, ali veliku ulogu ima sušnica, način soljenja, priprema robe u smislu da li se meso ohladilo nakon klanja, itd. Na kvalitet, higijensku ispravnost, kao i održivost utječu brojni faktori od pravilnog tehnološkog procesa proizvodnje do manipulacije finalnim proizvodom. Jedna od mogućnosti produženja roka upotrebe, održavanje bolje kvalite, kao i higijenske i mikrobiološke ispravnosti je i vakuumiranje gotovih proizvoda.

Exodontics is one of the most commonly performed procedures in veterinary dentistry. One of the essential steps in every dental procedure is taking preoperative and postoperative dental radiographs in order to determine the severity of the disease, root abnormalities and retained root fragments. Present case report describes a cat with signs of oral inflammation and discomfort after previous dental treatment due to signs of gingivostomatitis one month earlier. Thorough dental examination and dental radiographs revealed retained root fragments of teeth 208, 209, 308 and 309 on the left side of the maxilla and the mandible. Extraction of retained root fragments and alveolectomy were performed, followed by postoperative antimicrobial treatment. Three weeks after the procedure, the extraction sites were healing and the patient started showing usual behaviour.

La découverte en 2016 d’un fragment textile unique au musée du quai Branly – Jacques Chirac (mqB-JC) offre des indices matériels inédits pour étudier les maro ‘ura, parmi les attributs les plus emblématiques du pouvoir des ariʻi rahi, les grands chefs des îles de la Société en Polynésie aujourd’hui française. En effet, aucun exemple ne semblait jusqu’ici avoir survécu à la conversion de l’archipel au christianisme au début du xixe siècle. Une étude pluridisciplinaire s’engage alors. En partie présentée lors d’une exposition inaugurée en octobre 2021 au mqB-JC, elle révèle un essaim d’histoires, de données techniques et d’hypothèses que cet article interroge à l’aune de mécanismes mnémoniques complexes, de phénomènes d’oubli et de résurgence. Suite au retour de ce fragment à Tahiti en 2022, l’article retrace la biographie ancienne de l’objet et examine ses fonctions de support de mémoire ainsi que les pratiques techniques qu’il illustre. Selon différentes temporalités, il souligne les enjeux de la création, de l’usage et de la préservation des objets sacrés polynésiens, du xviiie siècle à nos jours.

Posljednjih nekoliko godina sve se više prepoznaje potreba sistemskog istraživanjafenomena vršnjačkog nasilja i njegovih različitih manifestacija vezanih za učestalost i vrste nasilja.Cilj ovog istraživanja bio je ispitati učestalost pojedinih oblika vršnjačkog nasilja u osnovnimškolama. Stavovi nastavnika i učenika se mimoilaze kada su u pitanju: slanje prostih slika nainternetu, namjernog uništavanja ličnih stvari, ignorisanja, praćenja i uhođenja, prijetećih pogleda,ucjena, pričanja laži, isključivanja iz društva, slanje prostih riječi SMS-om i putem Interneta,prijetnje, čupanje za kosu i tuča. Pokazalo se da su dječaci češće počinitelji vršnjačkog nasilja u obamjerenja. Zanimljivo je primijetiti rezultate istraživanja koji ukazuju da je od strane učenika učionicarangirana na prvom mjestu kao mjesto vršenja nasilja, dok je kod nastavnika školsko dvorište.Rezultati istraživanja kod učenika su ukazali na većinsku zastupljenost istovrsne reakcije u nasilnojsituaciji, većina učenika bi uzvratila istom mjerom. Uzroci nasilja po mišljenju nastavnika su u prvomredu zanemarivanje i vaspitanje od strane porodice, zatim nedovoljna saradnja roditelja i nastavnika,dok su reakcije koje se odnose za nivo osviještenosti vezane za sferu nenasilne komunikacije. U skladus dobijenim rezultatima može se zaključiti da je nasilje među djecom u školama prisutno i to urazličitim oblicima. Iz tog razloga postoji potreba sistemskog rada na rješavanju ovog problema kojipodrazumijeva ranu identifikaciju i prevenciju pojavnih oblika nasilja među vršnjacima, te rad saroditeljima i nastavnim osobljem koji svojim postupcima prenose obrasce ponašanja na učenike.

The Council of Europe Convention on the Protection of Children from Sexual Exploitation and Sexual Abuse (Lanzarote Convention) provides for the criminalization of all forms of sexual abuse of children. Also, this Convention stipulates that, in due time after ratification, European countries will take measures aimed at preventing sexual violence, but also pass special legal provisions that will refer to the protection of child victims and the criminal prosecution of perpetrators of this type of crime. In order to ensure the effective implementation of the Convention by the member states, a Committee of Member States, known as the "Lanzarote Committee", was established, which, in accordance with its Rules of Procedure, monitors the implementation of the Convention in the member states. In January 2018, the Lanzarote Committee completed its first round of monitoring entitled "Protection of children from sexual abuse in the circle of trust". In the paper, with reference to the Questionnaire of the Lanzarote Committee an overview of the compliance of legal provisions in the Republic of Srpska as part of Bosnia and Herzegovina will be presented.

U toku poslednje decenije, nasilje u partnerskim odnosima i nasilje nad ženama su aktuelneteme kojima se svakodnevno popunjava medijski prostor i kao takve se, veoma navalentno, namećukao težak izazov sa kojim se suočava društvo u cjelini. Nasilje u ovom segmentu, sa svim svojimelementima i karakteristikama, pod uticajem različitih egzogenih procesa, predstavlja kršenjetemeljnih ljudskih prava na život, sigurnost i dostojanstvo. Upravo zato zaštita fizičkog i psihičkogintegriteta žena jeste u fokusu brojnih međunarodnih dokumenata i međunarodnih standarda kojiimaju za cilj suzbijanje ovog problema kroz sistemske promjene. Nastojanje da se ukaže nakomplesnost partnerskog nasilja u savremenom društvu veoma je bitno zbog sve većerasprostranjenosti i novih pojavnih oblika ove vrste nasilja. Iako su već pokrenute brojne aktivnosti usmislu usvajanja različitih zakonskih i normativnih rješenja, okvirnih strategija i akcionih planova, jošuvijek je stanje na terenu veoma alarmantno na način da stvarni problemi sa kojima se suočavaju ženei djevojčice, koje su pretrpjele neki oblik nasilja, još uvijek u značajnom procentu ostaju neriješeni umnogim značajnim segmentima njihovog života.

In order to make the best possible use of the water potential and ensure the balance reserve for the needs of energy system regulation, it is necessary to optimally plan the operation of the hydroelectric power plant. The values of hydropower production are set in defined time intervals based on short- term planning obtained by optimizing the production mix from the balance responsible party, and data on water resources and availability of generators are also known. Under these conditions, optimal use of generators and the available amount of water from reservoirs should be foreseen. In HPPs with multiple generators, the selection of generators depends on pipeline losses, mechanical losses on turbines, electrical losses on generators, etc. The goal of planning should be the optimal use of water potential and the use of generators, and the result of the optimization is flows through generators and pipelines, such that the given production of the hydroelectric power plant is ensured. This objective is described by an objective function, which is defined by a non-linear relationship of several variables, in this case the degree of utilization and the flow of each unit individually. The obtained results for flows represent input data for further planning, mainly for planning the provision of a sufficient amount of water in the input building, for the production of the power plant, which practically means maintaining the height of the input building in the given range. The paper presents the procedure for obtaining and solving the objective function using a genetic algorithm (GA), with the simplest restrictions on the input variables. The principle of the genetic algorithm consists of evaluation, selection, crossover and mutation within a population. Through the iterative procedure of these four principles, through several generations, the solution of the objective function is obtained.

Equestrian sport is the only Olympic sport in which male and female competitors participate next to one another. The aim of this study was to analyze whether there is a link between the gender of the rider and performance, as well as whether there is a statistically significant difference between male and female riders at the beginner and intermediate level of competition in terms of jumping obstacles. The variables selected for analysis were the knock down, refusal, a fall in the parkour, faults committed during an approach on a straight line and an approach on a curve, faults committed in relation to the color of the obstacle, faults committed at single and combination obstacles, faults committed at the staccionata, oxer, and Liverpool, and faults committed during the double and triple jump. The performance indicator was defined as an outcome with no faults or an outcome with a fault committed during the jump. The analysis included 256 take-offs, from 12 jumping events at open regional club competitions of the CSN - A* category in 2022, held in Zagreb, and the CSN - A** category in 2023, held in Osijek. In total, 3065 jumps over 2683 obstacles were analyzed, 2345 of which were single and 329 combination. The results indicated a weak correlation between the gender of the rider and the performance indicators, whereby the Mann-Whitney U test did not determine a statistically significant difference between the gender of the riders when it came to the faults committed in relation to the studied variables. The number of female competitors is greater at the beginner and intermediate level at jumping events. A weak correlation was identified between the gender of the rider and the faults committed, whereby gender does not impact the performance. The analysis of the performance indicators for jumping obstacles can provide guidelines for coaches and riders alike in their future work with the aim of achieving a more successful sports performance. The analysis could also help the course designers to create a parkour with various levels of nuanced difficulty.
