Aim. The article deals with determining the features of cerebral energy metabolism in young people at different stages of adaptation in the Arctic region. Materials and methods. The level of permanent brain direct current potentials (DCP) was measured in 146 young people: 93 born and permanently living in the Arctic region and 53 migrants living in new climatic conditions for the first months. The study was conducted by using a “Neuro-KM” 12-channel hardware-software complex for the topographic mapping of brain electrical activity. DCP were recorded in the unipolar leads according to the 10-20 international system. Statistical processing of the data obtained was carried out with the software package SPSS-20 for Windows. Results. In young people permanently living in the Arctic region, we revealed functional asymmetry of the brain with right-hemisphere dominance in almost all leads. In migrants living in the climatic conditions of the Arctic region for the first months, we established high values of energy consumption and partial asymmetry of cerebral energy metabolism. Conclusion. Body functioning in the usual habitat is characterized by a stereotypical set of regulatory mechanisms. During adaptation, new ways of responding to changes in the environment are formed. The dominance of the right or left hemisphere occurs depending on the type of tasks. The analysis of interhemispheric asymmetry of energy consumption performed by using the method of brain mapping allows assessing the degree of dominance. The dominance of energy consumption in the left hemisphere may indicate a possible failure of adaptation mechanisms. Positive interhemispheric gradients indicate the correct performance of CNS regulatory mechanisms during adaptation to new environmental conditions

Abstract. The estimation of radon progeny in the Arctic region represents a scientific challenge due to the required low limit of detection in consideration of the limited radon emanation associated with permafrost dynamics. This preliminary study highlighted, for the first time, the possibility to monitor radon progeny in the Arctic region with a higher time resolution. The composition of the radon progeny offered the opportunity to identify air masses dominated by long-range transport, in presence or not of near-constant radon progeny instead of long and short lived progenies. Furthermore, the different ratio between radon and thoron progenies evidenced the contributions of local emissions and atmospheric stability. Two different emanation periods were defined in accordance to the permafrost dynamics at the ground and several accumulation windows were recognized coherently to the meteo-climatic conditions occurring at the study site.

Construction on problem soils or in permafrost conditions involves using of pile foundations with a ventilated space under the floor structure. In this case, additional thermal insulation is required under the first-floor structure (above the ventilated space). The aim of research was to develop insulation systems for buildings on pile foundations for different climatic zones, including conditions of the arctic region and other regions with a predominance of ever-frozen ground. With the help of the THERM computer program, the conditions of bidimensional heat interchange in the enclosing structures of a building with pile foundation were simulated. The resulting models were analysed in terms of the thermophysical characteristics of the structures. As a result, the optimal version of the insulation system was chosen, effective both in the climatic conditions of the midland and in the especially cold conditions of Yakutia and Trans-Polar region (The Subarctic). This system included insulation with mineral wool slabs along the facade walls, with extruded foamed polystyrene along the basement part and the floor structure, and with rolled foamed polyethylene (with the formation of a seamless insulation shell) along the ventilated space under the floor structure and above, on top of insulation boards.

Relevance. The professional activities of EMERCOM of Russia employees in the Arctic region are curried out in harsh climatic conditions, are associated with high social and professional responsibility, and potential risks to life and health.Intention – to predict the model of professional longevity of EMERCOM of Russia employees in the Arctic region. Methods. The study involved 176 EMERCOM of Russia employees divided into 3 groups depending on the length of professional experience in the Arctic region: group 1, 2 and 3 with length of service up to 5 years, from 5 to 10 years, and over 10 years, respectively. To determine the individual psychological characteristics, standardized psychological techniques were used.Results and Discussion. Based on questionnaires, the biomedical component of the professional longevity of EMERCOM of Russia employees was established. In Group 1, 11 % of employees had medium level of the biomedical component, 62% had a level above medium, and 27 % had a high level. With an increase in the professional experience in the Arctic region, the number of people with high biomedical component decreases – for example, in Group 3, there were no employees with high levels. Correlation analysis showed that the professional longevity of EMERCOM of Russia employees in the Arctic region was facilitated by such individual psychological characteristics as time orientation, support, value orientation, self esteem, self acceptance, acceptance of aggression, cognitive needs, personality, existential fulfillment, emotional stability, independence, responsibility, whereas pessimism, impulsivity, trait and state anxiety, depression, tension, depersonalization decreased the professional longevity. Using the stepwise regression, with the length of professional experience as a result, a model for forecasting the professional longevity of EMERCOM of Russia employees in the Arctic region was created; forecast probability is 84 % (p < 0.001). The level of the biomedical component of professional longevity and individual psychological characteristics (emotional sensitivity, existential performance, sociability, flexibility of behavior, individualism, courage) were highly significant.Conclusion. Taking into account the level of development of the biomedical component and such individual psychological characteristics as emotional sensitivity, existential fulfillment, sociability, flexibility of behavior, individualism, courage, will contribute to the professional longevity of EMERCOM of Russia employees in the Arctic region.

Development and improvement of the technologies in the field of geological exploration and mining, ship building, and navigation, along with the ongoing climate changes in the Arctic region, opened the new prospects. The region is involved in the active economic activities: new sea routes, discovery of large mineral deposits for the development, expansion of the opportunities for the scientific research. As the previous experience shows, the development of territories was often rashly in the pursuit of some resource, other natural resources and entire ecosystems were destroyed, the created economic objects caused harm to the human health and the environment, waste was accumulated, there were no conditions for normal life of people, etc. Conducted comparison study allows to note that all the countries are unanimous in their desire to develop the Arctic region based on the integrated approach gaining maximum profit while preserving nature and creating favorable conditions for human life. Each Arctic state developed the strategy that defines the goals, objectives, priorities, and areas of activity. In the future, in pursuance of strategic documents the programs are developed on the implementation of certain areas of development, regulatory legal acts are adopted, or the existing ones are supplemented in terms of establishing the requirements for conducting economic and other activities in the Arctic region. However, the detailed analysis shows that the normative regulation is not always consistent and transparent, considers the risks of conducting business and operations in a region with specific climatic conditions and a fragile ecosystem. In connection with this, the need in improving legislation is substantiated in order to actually provide an integrated approach to the implementation of activities in the unique region.
