For the purpose of determining the social status structure of male and female dancers, 103 male and 145 female dancers aged 18-28 actively engaged in folk dancing were tested. For the assessment of social status, only one model that allows for true scientific approach to studying the structure of stratification dimensions has been made so far. The model was constructed by Saksida and later served as a basis for many studies conducted by other authors as well （Saksida, Caserman, Petrovic, Momirovic, and Hosek）. Designed as a phenomenological model, it has undergone several changes over time, but it is still suitable for studying social change. The INST2 questionnaire modified by Boli, Popovic, Hosek, Momirovic, and Savic （SSMIN） was applied in this study. All the data obtained in this research were processed at the Multidisciplinary Research Center of the Faculty of Sport and Physical Education, University of Pristina, through the system of data processing programs designed by D. Popovic and K Momirovic. To determine differences between the groups, a method of discriminant analysis was applied.展开更多

Methods： Six female sheep with bilateral ovariectomyinduced osteoporosis were employed in this experiment. After EPS insertion in each femoral condyle, the sheep were randomly divided into two groups： 3 sheep were bred for 3 months （Group A）, while the other 3 were bred for 6 months （Group B）. After the animals being killed, the femoral condyles with EPS were obtained, which were three-dimensionally-imaged and reconstructed by micro-CT. Histological evalu-ation was made thereafter. Results： The trabecular microstructure was denser at the screw-bone interface than in the distant parts in expan-sive section, especially within the spiral marking. In the non- expansive section, however, there was no significant differ-ence between the interface and the distant parts. The regions of interest （ROI） adjacent to EPS were reconstructed and analyzed by micro-CT with the same thresholds. The three-dimensional （3-D） parameters, including tissue min- eral density （TMD）, bone volume fraction （BVF, BV/TV）, bone surface/bone volume （BS/BV） ratio, trabecular thickness （Tb.Th）, and trabecular separation （Tb.Sp）, were sig- nificantly better in expansive sections than non-expan-sive sections （P 〈 0.05）. Histologically, newly-formed bony trabeculae crawled along the expansive fissures and into the center of EPS. The newly-formed bones, as well as the bones at the bone-screw interface, closely contacted with the EPS and constructed four compartments. Conclusions： The findings of the current study, based on micro-CT and histological evaluation, suggest that EPS can significantly provide stabilization in osteoporotic cancellous bones.展开更多
