This study was conducted with aim to determine the relations between motor skills and technical and tactical characteristics of table tennis players. The study was conducted on a sample of 48 of the best seniors with aged 18-36 years old (a representative sample) in Bosnia and Herzegovina. For this purpose was applied the system of (12) variables to estimate the basic motor skills, and (8) variables for evaluation of technical and tactical characteristics of table tennis players. In order to determine the relations between the basic motor skills and technical and tactical characteristics of table tennis players, the method applied was the method of canonical correlation analysis. Establishing the link between these two areas resulted in the separation of one canonical factor which was statistically significant. The most significant information for extracted canonical component gives the coefficients of the structure and the cross-structure. The coefficients of the structure represent the correlations of the original variables with canonical component derived from a set of variables to which this variable originally belongs, while coefficients of cross- structure provide correlations of adequate source variables with canonical component that was created in other set of variables. Onto the isolated canonical function the most significant influence have the variables of hand tapping, throwing a medicine 1kg ball by forehand, boom in gray, long jump from the place, while also slightly smaller significance show other variables, but from the same subspaces of basic motor abilities. Based on the coefficients of the structure can be summarized that all the technical and tactical characteristics highly correlate with the factor isolated from this area which is logical, because all manifest variables represent one area (technical skills / playing skill). The variables that are related to the attack phase (initiative in points) and elements of game movement (the safety and effectiveness of the attack over the table, safety and efficacy of the first entrance, efficiency of game movement) are significantly associated with canonical factor isolated in the area of motor abilities. These variables describe technical structures in which “imposes” and maintains the initiative in the point, and are the most aggressive attack techniques, and generally seek the largest motor engagement. No surprises then that exactly these variables of technical and tactical structures are significantly associated with the factor isolated in the area of motor abilities are the most important.

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.
