Many studies have explored associations between radiation exposure and cancer among atomic bomb survivors in Japan, Chernobyl rescue workers, workers of nuclear industry in Germany and in a historical cohort of people who were exposed to the radiation from the Semipalatinsk nuclear weapons test site in Kazakhstan. Non-cancer consequences of radiation exposure have been less studied. We identified a few publications on associations between radiation and cardiovascular diseases, but most of them were conducted in Japan among Hiroshima and Nagasaki survivors and their offspring. In this population-based cross-sectional study (n = 1 755) we assessed associations between equivalent radiation dose and blood lipids among population of East Kazakhstan and Pavlodar regions who permanently live in close proximity to Semipalatinsk nuclear weapons test site. We studied total cholesterol, low- and high density lipoproteins as dependent variables across quartiles of the equivalent radiation dose using multiple linear regression with adjustment for gender, smoking, alcohol consumption, body mass index and region of residence. We observed significant positive association between equivalent dose and total cholesterol and low density lipoproteins, but not high density lipoproteins. Our results contribute to the understanding of the mechanisms between low dose radiation exposure and cardiovascular diseases

A culturological perspective of problems of ecology of childhood; approaches to formation of a problem field of childhood ecology in the context of development of ideas about the phenomenon of childhood and its transformation in the global world conditions, importance of cultural factors, education and professional competence of teachers in ecologization of childhood space, implementation of subjective potential of childhood in the big cultural creativity process on the basis of eco-cultural values have been grounded. It has been emphasized that environmental problems are not limited to the problem of childhood, environmental security, which in themselves are paradoxical (the need to protect people from the consequences of the environmental crisis generated by them). The problems make obvious the need to find causes of environmental problems in human culture and society, and their solution - in formation of a new cultural code based on interiorization by personalities and society of ecocultural values, their ecological culture.

This article describes a method of assessment of readiness of graduates of the medical school to psychological-educational activities based on the factor-criterion model. The model included cognitive, motivational, activity and personal factors and criteria which characterize them. The coefficient values of each factor and the criteria were determined by the Delphi method. Comparison of the criteria with use of the proposed method with the criteria of actual state allowed to perform maximally objective comprehensive assessment of readiness of the graduates to psychological-educational activities. The article has presented the quantitative and qualitative results of the Medical University graduates' self-preparedness for psychological-educational activity. It has been found that the overall level of preparedness of the graduates of the Faculty of General Medicine of the Northern State Medical University to psychological-educational activity corresponded to the nominal level. The teacher's personal example, direct contacts with patients in the course of training at the Medical University, the increased number of hours in the curriculum for studying of the psychological and educational aspects of the "doctor-patient" interaction at the clinical departments have been determined by the graduates of the Medical University as the main factors influencing quality of training for implementation of psychological-educational activity of future doctors. The assessment results can be a basis for correction and improvement of the content, forms and methods of psychological-educational training of future physicians.

Human ecology deals with a very important issue of life expectancy of indigenous people and new comers of the northern parts of the Russian Federation. The faster the northern territories are developed economically and industrially, the higher importance of prolongation of working age of new comers in the Khanty-Mansiysk Autonomous Area - Ugra and the Yamal-Nenets Autonomous Area is. There are four possible variants of new comers' life prolongation. Through the example of three age female groups of indigenous population, there has been considered the problem of dynamics of changing heart rates. In phase space of states, increased volumes of quasiattractors are equal to intensive physical activity. It has been proposed to use the regularity of these volumes' decrease for assessment of human aging dynamics in the North.
