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 article investigates the relationship between unemployment rate and development indicators: (1) the GDP per capita in Purchasing Power Parities (PPP in current international $); and (2) the Internet penetration rate, defined as the percentage of Internet users per 100 people. For 34 countries in 2013, only two simple linear regression models based on natural logarithms of data and the Ordinary Least Squares (OLS) estimator appeared to be useful. The simple linear regression "Model 1" shows a negative correlation between the main variable under study ln(Y_UemRate) and the regressor ln(X_GDPpc), explaining nearly half of the total variation. The simple linear regression "Model 2" shows a negative correlation between ln(Y_UemRate) and ln(X_IntUse), explaining 27 % of the total sum of squares. Regarding clustering of 34 countries based on three variables, the Ward linkage and squared Euclidean distances gave an interesting four-cluster solution. The South-East European (SEE), and especially to the Western Balkan's countries (WBC) are focused. These countries, spread in three clusters, are not homogeneous. Bosnia and Herzegovina and R. Macedonia are with Spain and Greece, all having difficult economic situation. Albania, Montenegro and Serbia are with Bulgaria, Romania and Turkey, all being the SEEC. Croatia is with more developed Italy, Cyprus and Poland, and with less developed Portugal. Central European Slovenia, joined more developed countries of that area, but the most developed European countries comprised a cluster of their own.

The research was conducted at the Department of Addictions of the Psychiatry Clinic in BanjaLuka in 2011/2012. It included two groups of examinees.One group was Experimental N (50) which consisted of alcohol addicts who had committed crime and misdemeanor offenses and the second one was a control group N (50) which consisted of alcohol addicts who had not commited these acts. The perpetrators of domestic violence are often treated at the Psychiatry Clinic following the Court verdict. The aim of the research is to study personality characteristics of alcohol addicts from these stand points: 1) What are the personality characteristics of alcohol addicts. 2) What are the personality specificities of alcohol addicts who have commited criminal acts or offenses and alcohol addicts who have not committed criminal acts and offenses. 3) Can the personality characteristics of alcohol addicts be taken into account indrawing up treatment guidelines for the prevention of relapse of criminal behavior and suggesting possible ways of sanctioning through the legal system. The research was conducted at the Department of Addictions of the Psychiatry Clinic in BanjaLuka in 2011/2012. It included two groups of examinees.One group was Experimental N (50) which consisted of alcohol addicts who had committed crime and misdemeanor offenses and the second one was a control group N (50) which consisted of alcohol addicts who had not commited these acts. The perpetrators of domestic violence are often treated at the Psychiatry Clinic following the Court verdict. The results showed that the offenders differ from non-offenders in the fact that they start drinking earlier, and they have a statistically significant difference in many categories of sociopathic characteristics in terms of problems in school,conflicts with law, conflicts within the family, and more often show aggression. Analysis of the personality characteristics shows statistical significance at the subscale of psychopathic deviation forthe perpetrators. Category of offenders is significantly more impulsive than non-offenders under all three components of impulsiveness: cognitive, motor and dispersal of attention. Everything mentioned above indicates the need for early prevention of alcohol and work with high-risk populations. On the other hand, there should be a better secondary prevention where, besides treating alcohol dependence, a group of perpetrators has a need for psychosocial treatment of anger control.

AbstractBackgroundSoccer is the most popular sport worldwide, with a long history and currently more than 500 million active participants, of whom 300 million are registered football club members. On the basis of scientific findings showing positive fitness and health effects of recreational soccer, FIFA (Fédération Internationale de Football Association) introduced the slogan “Playing football for 45 min twice a week—best prevention of non-communicable diseases” in 2010.ObjectiveThe objective of this paper was to perform a systematic review and meta-analysis of the literature to determine the effects of recreational soccer on maximal oxygen uptake ($$ \dot{V}{\text{O}}_{2\;\hbox{max} } $$V˙O2max).MethodsSix electronic databases (MEDLINE, PubMed, SPORTDiscus, Web of Science, CINAHL and Google Scholar) were searched for original research articles. A manual search was performed to cover the areas of recreational soccer, recreational physical activity, recreational small-sided games and $$ \dot{V}{\text{O}}_{2\;\hbox{max} } $$V˙O2max using the following key terms, either singly or in combination: recreational small-sided games, recreational football, recreational soccer, street football, street soccer, effect, maximal oxygen uptake, peak oxygen uptake, cardiorespiratory fitness, $$ \dot{V}{\text{O}}_{2\;\hbox{max} } $$V˙O2max. The inclusion criteria were divided into four sections: type of study, type of participants, type of interventions and type of outcome measures. Probabilistic magnitude-based inferences for meta-analysed effects were based on standardised thresholds for small, moderate and large changes (0.2, 0.6 and 1.2, respectively) derived from between-subject standard deviations for baseline fitness.ResultsSeventeen studies met the inclusion criteria and were included in the systematic review and meta-analysis. Mean differences showed that $$ \dot{V}{\text{O}}_{2\;\hbox{max} } $$V˙O2max increased by 3.51 mL/kg/min (95 % CI 3.07–4.15) over a recreational soccer training programme in comparison with other training models. The meta-analysed effects of recreational soccer on $$ \dot{V}{\text{O}}_{2\;\hbox{max} } $$V˙O2max compared with the controls of no exercise, continuous running and strength training were most likely largely beneficial [effect size (ES) = 1.46; 95 % confidence interval (CI) 0.91, 2.01; I2 = 88.35 %], most likely moderately beneficial (ES = 0.68; 95 % CI 0.06, 1.29; I2 = 69.13 %) and most likely moderately beneficial (ES = 1.08; 95 % CI −0.25, 2.42; I2 = 71.06 %), respectively. In men and women, the meta-analysed effect was most likely largely beneficial for men (ES = 1.22) and most likely moderately beneficial for women (ES = 0.96) compared with the controls. After 12 weeks of recreational soccer with an intensity of 78–84 % maximal heart rate (HRmax), healthy untrained men improved their $$ \dot{V}{\text{O}}_{2\;\hbox{max} } $$V˙O2max by 8–13 %, while untrained elderly participants improved their $$ \dot{V}{\text{O}}_{2\;\hbox{max} } $$V˙O2max by 15–18 %. Soccer training for 12–70 weeks in healthy women resulted in an improvement in $$ \dot{V}{\text{O}}_{2\;\hbox{max} } $$V˙O2max of 5–16 %. Significant improvements in $$ \dot{V}{\text{O}}_{2\;\hbox{max} } $$V˙O2max have been observed in patients with diabetes mellitus, hypertension and prostate cancer.ConclusionRecreational soccer produces large improvements in $$ \dot{V}{\text{O}}_{2\;\hbox{max} } $$V˙O2max compared to strength training and no exercise, regardless of the age, sex and health status of the participants. Furthermore, recreational soccer is better than continuous endurance running, albeit the additional effect is moderate. This kind of physical activity has great potential for enhancing aerobic fitness, and for preventing and treating non-communicable diseases, and is ideal for addressing lack of motivation, a key component in physical (in)activity.

The anatomical rationale and efficacy of the chin tuck in improving airway protection for some people with swallowing disorders have been well researched and established. However, there are still open questions regarding whether brain activity for swallowing control is altered while performing this chin-tuck maneuver. In this study, we collected EEG signals from 55 healthy adults while swallowing in the neutral and chin-tuck head positions. The time-frequency based synchrony measure was used to form brain networks. We investigated both the small-world properties of these brain networks and differences among the constructed brain networks for the two head positions during swallowing tasks. We showed that brain networks for swallowing in both head positions exhibit small-world properties. Furthermore, we showed that swallowing in the chin-tuck head position affects brain networks in the Alpha and Gamma frequency bands. According to these results, we can tell that the parameter of head position should be considered in future investigations which utilize EEG signals during swallowing activity.

We are considering a semilinear singular perturbation reaction-diffusion boundary value problem which contains a small perturbation parameter that acts on the highest order derivative. We construct a difference scheme on an arbitrary nonequidistant mesh using a collocation method and Green's function. We show that the constructed difference scheme has a unique solution and that the scheme is stable. The central result of the paper is \(\epsilon\)-uniform convergence of almost second order for the discrete approximate solution on a modified Shishkin mesh. We finally provide two numerical examples which illustrate the theoretical results on the uniform accuracy of the discrete problem, as well as the robustness of the method.

As a consequence of the current economic crisis many changes have been introduced to health systems on national levels to reduce expenditure and to introduce more cost-effective methods. Then recent developments in medical technology have led to a shift in the traditional framework of physician-patient responsibility in healthcare decision making. In this context, the health community urges, in any case, decision makers to ensure that all changes introduced are in accordance with health system values. This paper presents a new decision making platform, as a tool to facilitate shared decision making, to improve the quality and transparency of tactical and strategic decisions. This new application, based on analytic quantitative method, is a component of a wider distributed web system under development, which aims to inform the new effective health technologies supporting designers in the user need elicitation and early stage health technology assessments. A case study aiming to elicit the user needs affecting the decision of whether to adopt a new magnetic resonance imaging (MRI) is also presented.

The aim of this paper is to give a brief overview of research and the newest theoretical considerations on internet addiction classification and treatment. Over the past years we have been increasingly facing the so-called “new age” disease of internet addiction as a serious problem affecting numerous people, especially the young population who has made social networks and other internet contents a modus vivendi. A literature search was conducted for the purpose of locating information on prevalence, diagnosis and treatment of internet and computer addiction. Certain researchers and psychiatrists believe that the excessive internet use is a symptom of other disorders, such as depression and anxiety, or impulse control disorder. However, over the past few years a consensus has been reached that this constellation of symptoms is actually an addiction disorder. The American Society of Addiction Medicine (ASAM) has recently come up with a new definition, according to which addiction represents a chronic brain disorder. Consequently, the new American Classification of Mental Disorders (DSM-V) has introduced this form of addiction under the diagnostic category dubbed “cybernetic disorder”. The field of internet addiction is advancing rapidly through its official recognition as a separate and distinct addiction disorder. Some individuals with internet addiction are at significant risk and merit professional care and treatment. There are several treatments available, but the primary prevention is the most effective intervention. Family practitioners and psychiatrists should be taught to screen their patients for this disorder.

Mixing of complementary tree species may increase stand productivity, mitigate the effects of drought and other risks, and pave the way to forest production systems which may be more resource-use efficient and stable in the face of climate change. However, systematic empirical studies on mixing effects are still missing for many commercially important and widespread species combinations. Here we studied the growth of Scots pine (Pinus sylvestris L.) and European beech (Fagus sylvatica L.) in mixed versus pure stands on 32 triplets located along a productivity gradient through Europe, reaching from Sweden to Bulgaria and from Spain to the Ukraine. Stand inventory and taking increment cores on the mainly 60–80 year-old trees and 0.02–1.55 ha sized, fully stocked plots provided insight how species mixing modifies the structure, dynamics and productivity compared with neighbouring pure stands. In mixture standing volume (+12 %), stand density (+20 %), basal area growth (+12 %), and stand volume growth (+8 %) were higher than the weighted mean of the neighbouring pure stands. Scots pine and European beech contributed rather equally to the overyielding and overdensity. In mixed stands mean diameter (+20 %) and height (+6 %) of Scots pine was ahead, while both diameter and height growth of European beech were behind (−8 %). The overyielding and overdensity were independent of the site index, the stand growth and yield, and climatic variables despite the wide variation in precipitation (520–1175 mm year−1), mean annual temperature (6–10.5 °C), and the drought index by de Martonne (28–61 mm °C−1) on the sites. Therefore, this species combination is potentially useful for increasing productivity across a wide range of site and climatic conditions. Given the significant overyielding of stand basal area growth but the absence of any relationship with site index and climatic variables, we hypothesize that the overyielding and overdensity results from several different types of interactions (light-, water-, and nutrient-related) that are all important in different circumstances. We discuss the relevance of the results for ecological theory and for the ongoing silvicultural transition from pure to mixed stands and their adaptation to climate change.
