BACKGROUND The influence of social support on health was explored among gender and socio-economic groups with the aim of contributing to the explanation of socio-economic health differences among Slovak adolescents. METHODS The sample consisted of 2616 Slovak adolescents (52.4% male, 47.6% female, mean age 15 years). The data were assessed by a self-reported questionnaire including measures o...

Among the numerous factors that influence the pattern of children's growth and development there are factors of the changeable socio-economic environment. The inequalities among the socio-economic strata in the Hungarian society have increased during last decades. The main objective of the study was to examine the body structure of children and adolescents living in different socio-economic bac...

AIM To investigate the role of health risk behavior, such as smoking and alcohol consumption, in the explanation of socio-economic health differences among adolescents. The hypothesis of different exposure and the hypothesis of different vulnerability were explored. METHOD In the study carried out in 1998, the prevalence of health complaints of smokers vs non-smokers, alcohol consumers vs abs...

AbstructWe investigate a very general subset of 2-D, orthogonal, compactly supported wavelets. This subset includes all the wavelets with a corresponding wavelet (polyphase) matrix that can be factored as a product of factors of degree-1 in one variable. In this paper, we consider, in particular, wavelets with vanishing moments. The number of vanishing moments that can be aichieved increases wi...

The developed software modules provide on-l...

muscle fatigue assessment has been the basis of numerous studies, specifically, in neuromuscular rehabilitation and the applications of fessystems. various emgbased techniques, in time and frequency domains, have been investigatedover years for the detection and evaluationof this phenomenon. the main objective of this study has beento evaluate the efficiency of applying a number of techniques w...

background: muscle fatigue is an important issue in neuromuscular rehabilitation. better control of this phenomenon would result in better prevention of its consequent physiological damages. objective: to provide a mathematical representation of muscle fatigue as a function of time. methods: we conducted this study by combining the emg-based estimation methods of muscle activation with the avai...

introduction: purkinje cell (pc) output displays a complex firing pattern consisting of high frequency sodium spikes and low frequency calcium spikes, and disruption in this firing behavior may contribute to cerebellar ataxia. riluzole, neuroprotective agent, has been demonstrated to have neuroprotective effects in cerebellar ataxia. here, the spectral analysis of pcs firing in control, 3-acety...
