    To date, an extensive experience has been accumulated in investigation of problems related to quality, assessment of management systems, modeling of economic system sustainability. The studies performed have created a basis for formation of a new research area — Economics of Quality. Its tools allow to use opportunities of model simulation for construction of the mathematical models adequately reflecting the role of quality in natural, technical, social regularities of functioning of the complex socioeconomic systems. Extensive application and development of models, and also system modeling with use of supercomputer technologies, on our deep belief, will bring the conducted researches of social and economic systems to essentially new level. Moreover, the current scientific research makes a significant contribution to model simulation of multi-agent social systems and that isn’t less important, it belongs to the priority areas in development of science and technology in our country. This article is devoted to the questions of supercomputer technologies application in public sciences, first of all, — regarding technical realization of the large-scale agent-focused models (AFM). The essence of this tool is that owing to increase in power of computers it became possible to describe the behavior of many separate fragments of a difficult system, as social and economic systems represent. The article also deals with the experience of foreign scientists and practicians in launching the AFM on supercomputers, and also the example of AFM developed in CEMI RAS, stages and methods of effective calculating kernel display of multi-agent system on architecture of a modern supercomputer will be analyzed. The experiments on the basis of model simulation on forecasting the population of St. Petersburg according to three scenarios as one of the major factors influencing the development of social and economic system and quality of life of the population are presented in the conclusion

    Multidisciplinary study of a key section on the Laptev Sea Coast (Bykovsky Peninsula, east Lena Delta) in 1998–2001 provides the most complete record of Middle and Late Weichselian environments in the East Siberian Arctic. The 40-m high Mamontovy Khayata cliff is a typical Ice Complex section built of icy silts with a network of large syngenetic polygonal ice wedges, and is richly fossiliferous. In combination with pollen, plant macrofossil and mammal fossils, a sequence of ca 70 insect samples provides a new interpretation of the environment and climate of the area between ca 50 and 12 ka. The large number of radiocarbon dates from the section, together with an extensive 14C database on mammal bones, allows chronological correlation of the various proxies. The Bykovsky record shows how climate change, and the Last Glacial Maximum in particular, affected terrestrial organisms such as insects and large grazing mammals. Both during the presumed “Karginsky Interstadial” (MIS 3) and the Sartanian Glacial (MIS 2), the vegetation remained a mosaic arctic grassland with relatively high diversity of grasses and herbs and dominance of xeric habitats: the tundra-steppe type. This biome was supported by a constantly very continental climate, caused by low sea level and enormous extension of shelf land. Variations within the broad pattern were caused mainly by fluctuations in summer temperature, related to global trends but overprinted by the effect of continentality. No major changes in humidity were observed nor were advances of modern-type forest or forest-tundra recorded, suggesting a major revision of the “Karginsky Interstadial” paradigm. The changing subtypes of the tundra-steppe environment were persistently favourable for mammalian grazers, which inhabited the shelf lowlands throughout the studied period. Mammal population numbers were lowered during the LGM, especially toward its end, and then flourished in a short, but impressive peak in the latest Weichselian, just before the collapse of the tundra-steppe biome. Throughout MIS 3 and MIS 2, the climate remained very favourable for the aggradation of permafrost. No events of regional permafrost degradation were observed in the continuous Bykovsky sequence until the very end of the Pleistocene

    The purpose of this study is to present our vision of assessing the recreational potential of the territory (RPT) for its effective management. We suggest using this territory assessment method, which consists of two main stages: assessment of the recreational component of the natural environment and assessment of the necessary amount of investment to use the recreational biodiversity of the territories.The article analyzes the approaches and presents the results of a comprehensive assessment of the recreational potential of the forest lands of the Sverdlovsk region. Created a map ranking the Sverdlovsk region according to the results of research with application for developing a comprehensive assessment of RPT on the methods, developed on the basis of the theory of "games with nature": the method of structured comparison of RPT on the Hurwitz criterion, aspiring to the maximum and to identify the factors dominating the impact from the application of the Wald criterion. Based on the conducted research on the analysis of the influence of forests on the formation of recreational characteristics, the authors obtained weighted average generalized coefficients of recreational attractiveness of forests of different types in the forest management areas of the Sverdlovsk region and identified 10 forest-cadastre areas in the Sverdlovsk region. This paper also presents a developed and tested method for a comprehensive assessment of the recreational potential of forest lands in the territory of the Sverdlovsk region in order to attract investment. Preliminary investment volumes for the development of the Sverdlovsk region's RPT (based on the cost of forest biodiversity) are presented. We consider the proposed territory ranking to be a necessary indicator for effective management of the subject's territories. © The Authors, published by EDP Sciences.

    The relevance of the problem subject to the research is conditioned by the discrepancy between (a) the orientation of the modern vocational-pedagogical education on the result of the future teacher training that is based on the subject matter and contents, and (b) the need to develop pedagogical skills. The application of the gaming simulation within the process of pedagogical skills development takes such skills to a completely new level. A study of the process of pedagogical skills development at students of a vocational-pedagogical education by way of the gaming simulation is the purpose of the article. Experiment and research activities were carried out during four years. A pedagogical experiment using the specially developed programme allowing discovering the level of pedagogical skills development at the trainees is the leading method for the research of this problem. Research results: The article provides for a model for the education of a student of a vocational-pedagogical educational institution through the gaming simulation; a scheme for this model implementation has been developed. Article contents may be useful for lecturers and students of pedagogical higher education institutions at the monitoring of the education quality. © 2016 Fominykh et al

    Using vital teeth as supports for non-removable prostheses has a known beneficial effect on the rehabilitation of patients suffering from partial adentia. In this case, dentinal tubules remain exposed after their preparation, which leads to tooth hypersensitivity. At the same time, the effects of chemical and physical agents, as well as bacteria and their metabolic products may promote the development of pulpitis of teeth being a part of orthopedic structur

    The state of health and the level of physical fitness of children are the parts of a serious problem that needs to be solved by teachers of physical education as well, but under modern conditions, this is not always possible. This studyis devoted to the identification of problems related to the above-mentioned issue, in which 78 respondents – teachers ofphysical culture from 52 secondary schools – took part. As a result of the study conducted by the method of questioning, it was found out that the most difficult to implement is the section “gymnastics”. The main problems are: the poor health of schoolchildren and poor physical fitness, the lack of sports and gymnastic equipment, as well as the increased workload of gyms. As an option to overcome the difficulties arising in the implementation of the section “Gymnastics”, many teachers are considering the possibility of using fitness technologies, however, in practice, only a smaller part of respondents implement them. The conclusion was made that the implementation of the gymnastics section in full under modern conditions is difficult to achieve, this is proved by the fact that the section is implemented in full only in 22% of educational institutions. It is necessary to adjust the physical education program for schoolchildren (within the section “Gymnastics”) or create such conditions for conducting lessons under which teachers will be given the opportunity to implement the developed programs in full
