The environmental aspects of education include the study of the processes of adaptation of students to the effects of the school environment and increasing teaching loads. This problem most often ...remains an important problem of age physiology and school hygiene. However, its meaning is much broader. Modern studies of the adaptation of students to the effects of the school environment and increasing educational loads have intensified in connection with the tasks of transforming education in the direction of its ecological culture. Our study proceeds from the assumption that the possibilities of assessing the environmental friendliness or environmental culture of education may be associated with the development of an instrumental method for determining and analyzing heart rate variability, suitable for examining large contingents of students as part of such methods for assessing the environmental friendliness of education and its other characteristics as a screening method and monitoring. Evaluation of heart rate variability allows determining the state of the mechanisms of regulation of physiological functions of the human body, the activity of regulatory systems: the central nervous system, the autonomic nervous system, intracardiac processes of the heart, the balance of the sympathetic and parasympathetic divisions of the autonomic nervous system.
The introduction against Russia of “food sanctions” promoted the interest of scientists to analyze such scientific categories as “risks” and “threats” in the agricultural sector of the economy in ...terms of import substitution. Largely, the introduction of food sanctions is intended to reorient Russia’s foreign trade markets in order to find suppliers that are free from the current political environment. Reducing competition should help domestic agricultural producers to work effectively and reach a leading position in their food segment. The importance to study the emerging risks and threats in relation to the regional food supply system in the process of import substitution is connected with the fact that without proper understanding and analysis, a significant number of problems of economic, social and managerial relations in the food turnover both within the state and within the borders of a separate region can arise. In the article, the authors attempt to show the risks and threats of food security in the region in modern economic conditions.
The paper analyzes the theoretical foundations of social adaptation of children with autism spectrum disorders. Attention is focused on the widespread prevalence of autism not only in the Russian ...Federation, but also abroad, which makes the problem of social adaptation of children with autism spectrum disorders relevant today. The paper presents the data of a sociological survey on the problems of social adaptation and the organization of the educational process for children with autism. The paper reveals statistical indicators on the problems of autism in world practice and in the Russian Federation, focuses on disorders of the mental and psychological state, shows a deficit of emotional reactions, disturbances in the communicative sphere, and the lack of independence of children with autism. It is also noted that these children are immersed only in their own problems, not noticing the world around them.
In contemporary researches, heart rate variability is considered not only as the index of state of sympathetic and parasympathetic parts of VNS (that are providing cardiovascular homeostasis), but as ...an indicator of organism adaptation to changeable conditions of the environment6. ...from tat very positions, the development of heart rate regulation mechanisms in ontogenesis is considered. The reliability of the results is ensured by interrelation of the theory and practice of the study, supported by the use of scientific methods of correlation analysis, discriminant analysis, Box test, equality of covariance matrices, checking functions by Wilks lambda method, comparing means according to Ttest for independent samples, comparison of means according to T-test for paired samples, using canonical discriminant functions. ...at the beginning of the preparation period, we observed average data in MG and CG, functional class 4 of the athletes, and the stress index amounted 45-55 c.u. on average, that is within the normal range (Figure 5.) At the end of the preparation period, it was revealed that cardiorespiratory indices in MG and CG differ significantly. ...the application of differentiated approach during physical training with use of various levels motion activity regarding athletes' vegetative regulation types facilitates the optimization of functional state and overstress preventing.
Purpose of the study is to improve the motor-sensory system of young athletes based on the assessment of the functional state of regulatory systems. Materials and methods. The study was carried out ...on the basis of еру Specialized Children's and Youth Sports School of the Olympic Reserve (SCYSSOR) ?2 "Krasnyye kryl'ya" (Togliatti, Russia). The study involved 50 students who were divided into two groups of 25 people each, namely the main group (MG) and the comparison group (CG). To assess the functional state of the children's organism and determine parameters of the vegetative balance, neurohumoral regulation, the heart rate variability (HRV) analysis was used with the hardware-software complex "Varicard 2.51." The study of psychophysiological indicators was carried out with the help of the computer program "Researcher of Temporal and Spatial Properties of Human - Version 2.1." The following tests were used in it: determining the reaction time to a moving object (RMO) and determining the reaction time to a choice. These techniques are used as a physiological test to determine the level of the relationship between the processes of excitation and inhibition in the cerebral cortex, both in a state of relative rest and under the influence of physical exertion. The response time to a choice is one of the variants of a complex sensorimotor reaction, since it is necessary to differentiate the signal (one signal needs to be reacted, and the other one does not have to respond). To assess the technical and physical preparedness of the practitioners, a number of control tests (standards) were used. Results. As a result of optimization of the functional state of the regulatory systems in the schoolchildren of 8-9 years, the parameters of motor abilities and technical preparedness of the subjects are improving, as well as the psychophysiological indices of schoolchildren. Conclusion. The received data clearly demonstrates that at optimization of a functional condition of an organism of children there is more effective training to technical methods of game of volleyball and development of impellent abilities of engaged pupils of 8-9 years.
The paper presents the results of observations of the sporadic Es layer during the period of meteorological disturbances in Kaliningrad in October 2017 and 2018 under quiet geomagnetic conditions. ...During the meteorological storms (October 29–30, 2017 and October 23–24, 2018), significant changes occurred in the dynamics of the Es-layer critical frequency. Observations of atmospheric and ionospheric disturbances in the Kaliningrad region show that the delay between the ionospheric response and the moment of maximum disturbances in atmospheric parameters is about 3 hours. These phenomena at the heights of the E-region might have been caused by propagation of acoustic-gravity waves generated by convective processes in the lower atmosphere during periods of a meteorological storm. Intensification of turbulent processes in the lower thermosphere leads to an increase in the atmospheric density and, accordingly, to higher recombination rates. This leads to a rapid decrease in the concentration of ions and, consequently, to a decrease in the critical frequency of the sporadic layer below the sensitivity threshold of ionosondes.
The most important stages of risk and inspection object's (10) residual life assessment process should comprise not only defects detection and determination of their parameters (flaw detection ...measurements) but, which is more essential: - detection of local zones of developing damages - stress concentration zones (SCZs); - detection of the most dangerous SCZs, which are the most probable sites of an object's failure; - determination of stress-strained (energy) state parameters in the most dangerous SCZs; - determination of actual structural-mechanical characteristics of the material in SCZs; - evaluation of damage development rate and direction based on the revealed mechanism of damaging development.
