Application of a biomedical hardware-software complex for the study of ultradian rhythms by heart rate variability

The article presents the results of the study of ultradian rhythms by amplitudes (A) and periods (T) of spectral characteristics (HF, LF, VLF, ULF) of the heart rate variability method using the HOLTERLIVE software package in ISCIM6.0 statistical processing in men, participants in a trans latitudinal flight and landing on the Arctic islands. The analysis of THF and TLF of the shows the symmetry and stability of adaptive reactions, while the range of ultra-slow (TVLF) and ultra-slow (TULF) waves shows the asymmetry and instability of the adaptive processes of the body of participants in a trans-latitude flight and landing on the Arctic islands. The transitions of the amplitude (A) and periods (T) of the power of harmonics from symmetry to asymmetry revealed in the examined people characterize the transitional states in the regulation's control of the heart rhythm

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

Gender differences in adaptive reactions of students in the development of educational innovations as a factor of sustainable development

The sustainability of the development of society depends and is secure by the safety of health of human capital. The article presents the results of a study of gender differences in adaptive reactions of students in the development of educational innovations using the non-invasive method of heart rate variability. Comparative analysis of heart rate measurements among the surveyed students showed that both boys and girls had tachycardia during the lessons. In boys, an increase in the stress index revealed that was reliably associated with the tension of the parasympathetic system, and in girls - the sympathetic system of autonomic regulation of heart rhythm control. A wide individual range of adaptive reactions of the cardiovascular system of young men and women to the impact of ICT revealed. The data obtained more indicative of biological (sex) differences in adaptive responses in the implementation of information technology in education. Our research has shown gender differences in adaptive responses. We observed a significant correlation between stress and the reaction of the autonomic nervous system. It is necessary to prevent the disturbance of the adaptive of the body. Therefore, we must create a safe environment for the health of students. It is desirable to reduce the time spent in the information space (up to 80 minutes, followed by a break). Since the research conducted on a small sample and one educational institution, it is necessary to research this issue on a larger representative sample

The psychological safety of students in the context of digitalization as a factor of social health

The article provides a rationale for the need to study psychological safety as a factor of social health of the intensive development of digitalization. Students, teachers, parents of various social groups become hostages of colossal information, which is contradictory and affects the social norms of the culture of specific peoples. Education is becoming more inclusive. Social cognitive dissonance arises, negatively affecting the social health of participants in education. The paper presents a model of the concept of psychological safety of students, which includes the following components: 1) safe digital content, taking into account age characteristics and ethnic and confessional values; 2) preservation and strengthening of social health; 3) self-development of personal and professional qualities of participants in education, taking into account the cognitive needs and analysis of the digital footprint

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

Problems of Professional Self-Development Among Undergraduates in the Digital Space, Identified During the COVID-19 Pandemic

The article examines the problems of professional self- development among undergraduates in the digital space, identified during the COVID-19 pandemic. The results of the study showed that students have characteristics that are necessary for further personal growth. They want to know themselves and ready to change and learn new things, improve themselves. Conducted during a pandemic and distance learning in self- isolation showed that 50% of students expressed satisfaction with this form of education, explaining their opinion with a high level of independent search for the necessary information, opportunities for self-development, self-realization, and self-improvement. Among the difficulties of distance learning, all surveyed identified: search and critical analysis of digital information; communicative dissatisfaction, the need for approval. The surveyed students in their self-development need a micro- and macro- environment that would create a secure creative educational space. It is necessary to search for new solutions to overcome psychological barriers associated with the need for self-development as future highly qualified specialists in the context of modern trends in the development of digital education

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

The value of digital technologies in inclusion

The article considers the importance of digital technologies in inclusion. The work used the analysis of literary sources and the method of heart rate variability. The results of the study showed that the introduction of digital technologies expands the problematic field of inclusive education. Students who have impaired health indicators in the context of the use of digital technologies, including in a remote format, should be attributed to inclusion. In this regard, the training of specialists in the field of cyberspace is a link between the development and implementation of new information technologies in an inclusive educational space and monitoring the health of students

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
