A person's living in different environmental conditions also determines his special mental properties, such as memory, thinking, and attention. The aim of this work is to study the quality of students' attention aged 12-17 years living in different climatic and geographical regions: the city of Surgut of the Khanty-Mansi Autonomous Area and in the rural areas of central Russia (Samara region). Pupils of the first group live in extreme climatic conditions of the North, which are made worse by adverse social and environmental factors of urbanization. Pupils of the second group live in a climatically and environmentally friendly area with minimal impact of man-made pollution. The method of the Bourdon correction test was used in a modification proposed by P. A. Rudik. Result. A comparative statistical analysis of the results obtained in the evaluation of the attention properties of different age groups of students was carried out. The dynamics of changes in the K, E, A indices were studied, and the coefficients as a whole were calculated for the entire test and for each minute of the experiment. Specific features of the student's attention development were defined. Age and gender differences, differences in the development of attention indicators in students from two different schools were revealed. Conclusions: statistically significant differences (p < 0.001) of attention distribution and productivity were revealed: the attention efficiency coefficient of Surgut students is 1.15 times lower than that of their peers from the Samara region. All this demonstrates the differences in the attention parameters of students in different ecological zones.

The aim of the work is to assess the impact of climate change in vital activity of northerners and the creation of prerequisites for developing a strategy for adaptation to climate change in the Komi Republic (RK). Methods. In the framework of a differentiated approach, the assessment was made for the North-West Federal District (NWFD) of Russia as a whole and for Komi Republic in detail. An objective approach included the study of scientific literature, an assessment of statistical data on air temperature, ambulance calls, tick bites, tick-borne encephalitis, injuries sustained during the ice, correlation analysis for ICD-10 diseases and socio-demographic indicators. Within the framework of the subjective approach, the results of a sociological survey were assessed using the method of Internet survey and interviewing specialists and representatives of the authorities in the field of health care in Komi Republic. Results. A correlation analysis conducted to establish the relationship between climate and socio-demographic indicators in the regions of the North-West Federal District revealed a strong dependence of the number of ambulance calls for diseases of arterial hypertension, class I diseases 22.64; T 33; J 01,11,20 in Syktyvkar municipal area and due to illness T 33 Vorkuta municipal area from the average monthly air temperature. The mapping method showed that with climate change, new foci of tick bite registration appeared. A sociological survey has determined that the population feels mainly the warming of the winter period. Experts and government officials confirm the fact of climate change and its impact on the health and economy of the region, but do not consider this a serious problem, pleading need for additional research. Conclusions. The results of the study are a comprehensive assessment of the impact of climate change on the life of the population of the Komi Republic from different points of view: a sociological survey of local residents, interviewing specialists and government officials and the dynamics of climate change in the region, which can become a prerequisite for the development of a regional strategy for climate change adaptation.

The aim of the work is a methodological justification of the interdisciplinary scientific research conducted by the authors on the phenomenon of human resilience in the extreme living conditions and activities in the Arctic region of the Russian Federation from the perspective of a sociologist, doctor and historian. The specifics of the author's project is to find an answer to the question about the sources of viability of the indigenous population of the Arctic territories based on historical and sociocultural data of people's way of life in extreme climatic conditions and objective reflection in medical genetic research. The authors note that modern medical science is mainly focused on studying the negative effects of a person's stay in the Arctic, as well as on the socio-medical analysis of deviations that arise among small indigenous peoples when changing climate and lifestyle. The authors conclude that the indigenous population of the Arctic has accumulated sufficient sociocultural experience and has a genetic originality drawn up in previous eras, which should be the object of an interdisciplinary study. The formulated idea was supported by the RFBR grant. This article makes an attempt to present the author's research concept to the scientific community.

The aim is to study the environmental friendliness of long-term work on a computer based on the results of assessing the level of psycho-physiological functions of students with different volumes of training loads using computer technologies in the learning process. Methods: computer analysis of psychomotor reactions, self-assessment and situational anxiety, measurement of heart rate (HR) and blood pressure before and after the local load. 86 volunteer students aged 18-23 years old with a different volume of computer technology in the curriculum were surveyed. The results showed that adaptation to training loads in students with a large amount of computer technology is expressed in a statistically significant increase in indicators such as the speed of simple sensomotor reactions, the rate of complex sensomotor reactions in girls, and a decrease in attention concentration, the rate of selection and discrimination reactions in all subjects. Anxiety rates were higher in students with less computer work. The response of the heart rate to the local load in girls of both groups was more pronounced than in boys. Conclusion. A theoretical statement is formulated about the uneven changes in adaptation processes to study loads in students with a large amount of computer technology, expressed in stimulating certain neurodynamic functions and compensatory reduction of others. The stress of adaptation in girls is more pronounced than in boys. These studies indicate the environmentally unfavorable nature of high computer loads on the body, which manifests itself in functional stress. It is necessary to introduce correctional and recreational activities in the educational process with a large amount of computer technology.
