The beginnings of Sokolism bind to the second half of the 19th century, namely to the Czech Miroslav Tyrš and its system of physical exercise. After the founding in the Czech Republic, Sokol movement began to spread in all Slavic countries as well as in those where Slavic nations lived. In this way, Sokolism arrived among Serbs who lived in America (USA), and they began to accept the idea of Sokolism in the mid-1907. In early 1909 began to appear the first initiatives for the establishment of Serbian Soko Societies. During 1909 two societies were founded, the in the next year five more, in 1911 three societies and in 1912 more than ten. In the second half of 1911 was established the union of Serbian Soko societies in America called Serbian Soko Parish in America (SSPA). Serbian Soko Society in Cleveland, Ohio, which is also the main subject of this research, was founded in the first half of 1912. The aim of the authors is to explore and present the exact date of the founding of this Society, the main initiators and founders, members and activities of the Society during its work. In this study authors used the historical method.

We demonstrate a distributed and a centralized 4G/5G compliant approach to minimize signaling and latency related to user mobility in cellular networks. This is crucial due to the densification of networks and the additional signaling introduced by the new 5G service-based architecture. By exploiting standardized protocols, our solutions dynamically reorganize the association between nodes in radio access network (RAN) and the core. We validated the proposed approaches using real user mobility datasets. Our results show that both our distributed and centralized solutions significantly reduce the signaling between core and RAN compared to the traditional approach based on geographical proximity. As a result, both approaches significantly reduce the average handover procedure processing time. Moreover, by relying on locally available information, the distributed approach can quickly adapt to changes in the user movement patterns as they happen.

To manage mobility, RAN nodes in both 4G and 5G are grouped into a hierarchy of geographical areas. We demonstrate a 4G/5G compliant Network Level Mobility Management Optimization solution based on User Equipment (UE) Mobility to minimize signaling (i.e., handover signaling, paging and tracking area updates) and handover latency by dynamically reconfiguring the association between nodes in the Radio Access Network (RAN) and nodes (e.g. Mobility Management Entity), functions (e.g. Access and Mobility Management Function) and Location Regions (e.g. Tracking Area, Registration Area, Tracking Area List) in the core network.

A significant number of old unreinforced load-bearing masonry (URM) buildings exist in many countries worldwide, but especially in Europe. In particular, Bosnia and Herzegovina has an important stock of masonry buildings constructed from the 1920s until the 1960s without application of any seismic code, due to their nonexistence at that time. With the 1963 Skopje earthquake, this class of buildings were shown to be rather vulnerable to seismic actions, which exhibited serious damage. This article assesses the seismic vulnerability of a typical multi-storey residential unreinforced load-bearing masonry building located in the heart of Sarajevo, which may be exposed to an earthquake of magnitude up to 6 by Richter’s scale. The buildings of this kind make up to 6% of the entire housing stock in the urban region of Sarajevo, while in Slovenia this percentage is much higher (around 30%). The analysis of a typical building located in Sarajevo revealed its drawbacks and the need for some kind of strengthening intervention to be implemented. Additionally, many structures of this type are overstressed by one to two additional floors (not the case of the analyzed structure) constructed from 1996 onwards. This was due to the massive population increase in the city center of Sarajevo and further increased the vulnerability of these buildings.

This paper presents a new technique of generation of convex polygon triangulation based on planted trivalent binary tree and ballot notation. The properties of the Catalan numbers were examined and their decomposition and application in developing the hierarchy and triangulation trees were analyzed. The method of storage and processing of triangulation was constructed on the basis of movements through the polygon. This method was derived from vertices and leaves of the planted trivalent binary tree. The research subject of the paper is analysis and comparison of a constructed method for solving of convex polygon triangulation problem with other methods and generating graphical representation. The application code of the algorithms was done in the Java programming language.

Summary Background HIV infection is characterized by progressive depletion of CD4+ T cells due to their reduced synthesis and increased destruction followed by marked activation and expansion of CD8+ T lymphocytes. CD4/CD8 ratio was traditionally described as a marker of immune system ageing in the general population, but it increasingly appears as a marker of different outcomes in the HIV-infected population. The main objective of this study is to examine the power of CD4/CD8 ratio in predicting the occurrence of metabolic syndrome (MetS) in HIV-positive patients receiving cART therapy. Methods 80 HIV/AIDS subjects were included in a retrospective case-control study. Flow cytometry was used to determine the percentage of CD4+ and CD8+ cells in peripheral blood of these patients. The values of biochemical parameters (triglycerides, HDL, blood sugar, blood counts), immunological parameters (CD4/CD8, PCR), anthropometric measurements and type of cART therapy were evaluated in this study. Results After six months of cART therapy 19 (23.8%) subjects had all the elements necessary for making the diagnosis of MetS. Using multivariate analysis CD4/CD8 ratio was statistically significant (p < 0.05) and had the largest effect on development of MetS (Wald = 9.01; OR = 0.45), followed by cART (Wald = 7.87; OR = 0.10) and triglycerides (Wald = 5.27; OR = 1.7). On the other hand, body weight and waist circumference showed no statistically significant effect on the development of MetS after six months of cART, p > 0.05. Conclusions CD4/CD8 ratio proved to be a significant marker for prediction of metabolic syndrome in HIV/AIDS patients.

Objetivo: Conhecer as vivências de adolescentes acerca do autocuidado. Métodos: Estudo qualitativo, entrevistas semiestruturadas foram conduzidas com 14 adolescentes, entre 12 a 18 anos, cadastrados em laboratório de endocrinologia pediátrica na cidade de Fortaleza, CE. Resultados: Com base nos dados desvelados observamos os seguintes enfrentamentos: adesão ao autocuidado; dilemas de ser adolescente com diabetes e ações do profissional de saúde e da família para o autocuidado do adolescente. Conclusão: Esta pesquisa com adolescentes portadores de diabetes demonstrou a importância do autocuidado apoiado como uma ferramenta que poderá ser operacionalizada por profissionais e família, favorecendo a adesão ao tratamento.

For the purpose of making of a solid body of an electric guitar the acoustic- and mechanical properties of walnut- (Juglans regia L.) and ash wood (Fraxinus excelsior L.) were researched. The acoustic properties were determined in a flexural vibration response of laboratory conditioned wood elements of 430 × 186 × 42.8 mm used for making of a solid body of an electric guitar. The velocity of shear- and compression ultrasonic waves was additionally determined in parallel small oriented samples of 80 × 40 × 40 mm. The research confirmed better mechanical properties of ash wood, that is, the larger modulus of elasticity and shear modules in all anatomical directions and planes. The acoustic quality of ash wood was better only in the basic vibration mode. Walnut was, on the other hand, lighter and more homogenous and had lower acoustic- and mechanic anisotropy. Additionally, reduced damping of walnut at higher vibration modes is assumed to have a positive impact on the vibration response of future modelled and built solid bodies of electric guitars. When choosing walnut wood, better energy transfer is expected at a similar string playing frequency and a structure resonance of the electric guitar.
