Comparative characteristics of ultradian rhythms of critical infrastructure employees under various conditions of professional activity

The article gives a comparative description of the ultradian rhythms of workers in critical infrastructures in various conditions of professional activity. In connection with the need to conduct repair and adjustment work, workers in critical infrastructures carry out their labor activities, often migrating to areas remote from their permanent place of residence. The study of the relevance to the health and functional capabilities of the body of workers in critical infrastructures according to ultradian rhythms has not been sufficiently studied. The study used the software-statistical complexes “Varicard” and “HolterLive” in the statistical processing “ISCIM6.0”. The HRV indicators were studied in a group of ground service workers in the usual natural and climatic production conditions and in a group of landing on the Arctic islands to perform repair and adjustment work. Studies have established that both groups experienced an energy-deficient state, which reduces resistance and causes an overstrain of the adaptation mechanisms of the autonomic nervous system in controlling the regulation of the heart rhythm. The results of the study showed that intense workload in extreme conditions of extreme professional activity negatively affects the state of health characteristic of maladaptation

Functional behavior of workers and employees in the industrial disaster prevention system

The study of the functional behaviour of workers and employees in the industrial disaster prevention system is a relevant research topic. Situations related to the human factor require the development of psychodiagnostic techniques that are sensitive to the state of the body and ensure the safety of the production process. Our research results show that men aimed at solving production problems solve them faster, more efficiently than they solve women faster, and more efficiently than women do. Men focused on emotions, experience significantly more emotional burnout in professional activities. Most men and women working in the workplace have an average level of coping with stress. In male workers, in fulfilling professional tasks, stable adaptation arises. They often find themselves in various extreme conditions/situations than male employees and contributes to the resistance of workers to a complex of stress factors of various nature

Assessing fertility complexity of Agro-gray soil on the East European Plain using correlation-regression analysis

According to classical concepts, soil fertility is an integrating indicator of soil properties. Correlation-regression analysis allows for the evaluation of the complexity of Agro-gray soil fertility in the East European Plain of Russia. The participation of all recorded soil properties and their equal contribution is the criteria for optimal assessment. The initial data array on soil properties divided into two clusters using the cluster analysis method. The absence of significant differences between clusters and some parameters in the model determined the need for correction. An acceptable level of fertility of Agro-gray soil established. The minimum requirements for the soil include 3.2% humus, 181 mg/kg of mobile phosphorus, and 144 mg/kg of exchangeable potassium pH and 1.5 mg-eq/100 g, respectively, the ratio of saturation of the soil with bases is not lower than 92%. With such a numerical combination of soil properties, the complexity of fertility ensured

Ecological attitude and motivation as a factor of social health for the biosphere values of the individual

The paper presents an analysis of the environmental motivation of the personality of young students as a factor in social health. The results of the study showed that young men, in interaction with nature, take an active life position aimed at the formation of bio-spheric values. The passive ecological motivation and attitude of girls is aimed at aesthetic contemplation of nature, but their ethical attitude towards harmony with nature ensures social well-being, and hence the social health of society. The positive development of bio-spheric values as a factor of social health depends on the rational, pragmatic ecological motivation and attitude of young men, as well as the ethical attitude of girls towards interacting with nature

Assessment of driver biorhythms as a factor of labor safety

The paper provides a biorhythmological assessment of the health of a driver’s team in conditions of joint activity in terms of heart rate variability. Measurements were taken during the working day using Holter monitoring in AnnaFlash2000 software and statistical processing ISCIM6. The cardiogram of the heart was recorded during the working day from 8.00 to 18.00 hours. It was revealed that the rhythmic processes of acrophase and heart rate bathyphase, which testify to the leading role of hypoxia, hypercapnia and desynchronosis of ultradian rhythms, influence the joint professional activity of drillers. The examined drivers found a violation of the synchronization of biological rhythms and desynchronosis at various levels of regulation of heart rhythm regulation. Both drivers, working in different biological rhythms, have a low degree of compatibility and belong to the group of production risk, which negatively affects occupational safety

Assessment of public health of production workers according to HRV

The study of the social health of labour resources as human capital is an actual problem. In production workers, the vegetative status was studied in terms of heart rate variability. By the concept of autonomic reactivity A.M. Greenberg, the results of the study found that the vegetative status of male employees and workers differs. The employees performing functions related to the organization of the production process showed general sympathicotonia. Workers performing specific production tasks have a general sympathicotonia. The results of the study found that vegetative status makes it possible to assess the social health of production workers. In the context of the intensive introduction of neural networks and nanotechnology into industrial production, the number of employees will increase. As a result, there will be an increase in the likelihood of cardio- respiratory system diseases among this contingent of workers. This will entail the development of corrective programs for the prevention of diseases of the cardiovascular system, and the introduction of changes in the classifier of occupational diseases
