Los objetivos de este estudio fueron investigar la asociacion de indice de masa corporal (IMC) con diferentes dimensiones de la percepcion de si mismo y el nivel de autoestima de las estudiantes de la Universidad de Tuzla. El estudio se realizo sobre una muestra de 120 estudiantes del primer y segundo ano en la Universidad de Tuzla y utilizo los siguientes instrumentos: Escala de Autoestima de Rosenberg (ROSF), Cuestionario PD forma A y calculo del IMC. Los resultados indicaron que el autoestima y autovaloracion, junto con una sensacion de comodidad e incomodidad afectan la experiencia de percepcion del cuerpo, sin tener relacion con el IMC. Tambien se determinaron cuales fueron variables predictoras significativas de la experiencia de percepcion corporal y el nivel de autoestima en la muestra examinada, indicando una correlacion significativa entre la autopercepcion y la sensacion de bienestar relacionadas con la imagen corporal en el autoestima de los estudiantes analizados, los cuales podrian no estar relacionados con la apariencia corporal real en terminos de reduccion o aumento de peso corporal.

Osnovni cilj ovog istraživanja bio je utjecaj pojedinih motorickih sposobnosti na natjecateljsku uspjesnost stolnotenisaca. Uzorak ispitanika cinilo je 48 najboljih seniora uzrasta 17-36 god (reprezentativni uzorak) u Bosni i Hercegovini. Uzorak ispitanika je odabran na osnovu kvalifikacionog turnira svih registriranih stolnotenisaca Bosne i Hercegovine. Mjerni instrumenti za ovo istraživanje su: dvanaest varijabli za procjenu bazicnih motorickih sposobnosti i jedna varijabla za procjenu natjecateljske uspjesnosti u stolnom tenisu. Metode obrade rezultata ukljucivale su deskriptivne statisticke procedurei multiplu regresijsku analizu. Motoricki prediktori primjenommultiple regresijske analize znacajno su objasnili kriterijsku varijablu natjecateljska uspjesnost stolnotenisaca.Na osnovu rezultata multiple regresijske analize koja je sprovedena na sest neovisnih, prediktorskih varijabli iz skupa bazicne motoricke sposobnosti i pozicije ispitanika na rang ljestvici stolnotenisaca (BODRNG), kao i ovisnom varijablom natjecateljske uspjesnosti, uz koristenje enter metode, dobivena je jedna statisticki znacajna regresijska funkcija. To ukazuje na to da između navedenih varijabli postoji linearna povezanost. Dobiveni koeficijent multiple korelacije je statisticki znacajan i iznosi R=.65, sto govori da se oko 41% varijance rezultata varijable pozicija ispitanika na rang ljestvici stolnotenisaca (BODRNG), može objasniti uz pomoc ukljucenih prediktorskih varijabli. Kao ukupno gledano najznacajniji prediktor može se izdvojiti varijabla tapinga rukom, to jest varijabla za procjenu frekvencije pokreta. Međutim, ne treba zanemariti i varijable za procjenu eksplozivne snage i to kako onih za procjenu apsolutne, tako i procjenu relativne eksplozivne snage.

The study was conducted on a sample of 92 participants at the age of 13-15, who were in the training process at least a year. The sample of participants is composed of two groups of judo athletes, 50 from Macedonia and 42 from Bosnia and Herzegovina. The aim of this study was to compare the anthropological dimensions between these two groups of participants. For the purposes of this study 28 variables were used: 9 variables for anthropometrical measures, 14 variables for motor dimensions and 5 variables for assessing situational movement structures of judo athletes. The univariate and multivariate statistical methods were identical in some anthropometrical measures, in particular the motor skills and situational movement structures of judo athletes, between groups.

Modern soil tillage systems based on different tools than mouldboard plough have very often stronger weed occurrence, which can be a serious problem for achieving high yields. An obvious solution for weed suppression is a herbicide, whose improper use can deteriorate environment and lead toward serious ecological problems. In order to investigate the interaction between soil tillage and herbicide, trial was set up in Valpovo in seasons 2008/09 - 2010/11. Two soil tillage systems (CT-conventional tillage, based on mouldboard ploughing, and CH-chiselling and disk harrowing, without ploughing) and five herbicide treatments (NH-control, no herbicides; H10- recommended dose of Herbaflex (2 l ha-1); H05-half dose of Herbaflex; F10- recommended dose of Fox (1.5 l ha-1); and F05-half dose of Fox) were applied to winter wheat crops. Results showed similar effects of soil tillage on the winter wheat yield, whereas different herbicide dosages showed similar weed suppression and influence on winter wheat yield.
