Introduction. T e leading place in the structure of occupational morbidity of agricultural machine operators is occupied by vertebroneurological diseases, the development of which can be associated with the impact of ergonomic factors of labor activity. T e aim of the study is to assess the ergonomic factors of working conditions on mobile agricultural machinery and to identify their impact on the formation of health disorders of agricultural machine operators. Materials and methods. Complex physiological and ergonomic researches at operation of tractors and combine harvesters of old samples of domestic production including an assessment of the organization of workplaces on compliance to requirements of ergonomics and anthropometric data of workers, temporary, statodynamic, biomechanical characteristics of working poses and movements, a functional condition of machine operators (130 people aged 20–45 years with professional experience of work not less than three years) in dynamics of a work shift are carried out. Anthropometric studies were conducted among male machine operators (663 people) aged 18–59 years and with experience in the profession for more than three years. Results. The discrepancy between the size and space-layout parameters of workplaces ergonomic requirements and anthropometric data of machine operators, causing the formation of uncomfortable working positions, increasing physical activity and the severity of the labor process. A high degree of correlation between changes in the parameters of the neuromuscular system and the severity of the discrepancy between the ergonomic parameters of anthropometric characteristics of machine operators (r=0,7). T e results of the research allowed to determine the priority measures for the prevention of vertebroneurological diseases in agricultural machine operators. Conclusions. T e organization of workplaces on domestic tractors and combine harvesters of old samples does not meet the ergonomic requirements and anthropometric data of machine operators, which is the reason for the formation of an uncomfortable working posture, increased statodynamic physical activity, early development of fatigue and fatigue in the process, which can cause the development of pathological conditions of the spine and ligamentous apparatus. Ergonomic improvement of workplaces is one of the priority measures to preserve the health of agricultural machine operators.

The Impact

The prevention of work-related health disorders is a priority in hygiene and preventive medicine. However, little attention has yet been paid to occupational health issues for agricultural workers. The purpose of this research was to assess the current state and develop measures to improve working conditions during the operation of self-propelled combine harvesters, the most widely represented in the existing machine and tractor fleet of agriculture in Russia. Measurements and hygienic assessment of the parameters of the factors of the production environment and the labor process in real production conditions have been carried out. The research results showed that the working conditions on self-propelled combine harvesters are characterized by a complex effect on workers of unfavorable factors (dustiness of the air in the working area, microclimatic discomfort, noise, general and local vibration, physical and sensory-emotional overload), the levels of which to varying degrees exceed hygienic standards. (classes 3.1–3.4). It has been established that the main reason for the formation of harmful working conditions is the operation of morally and physically worn out equipment. It is shown that the impact of an unfavorable production environment can serve as a risk factor for the emergence and development of general and occupational pathology among agricultural machine operators. A set of measures has been developed to ensure safe working conditions and reduce the risk of health disorders for machine operators, including normalizing the microclimate, reducing noise, vibration, dustiness in the air in the working area, optimizing the working posture, and introducing rational modes of work and rest. However, the basic measure that minimizes the adverse impact of professionally determined production factors on the health of agricultural machine operators is the complete replacement of the outdated machine and tractor fleet with agricultural machinery of new generations and compliance with the terms of its operation.

The Impact

In recent years, the problem of deteriorating health of students studying in a distance format has been very urgent. On the one hand, the volume of the teaching load, including interesting educational programs in the online format, is increasing; on the other hand, there are no sanitary rules governing the requirements for the educational process in universities. The research purpose is to establish the features of health disorders of distance learning students. A survey was conducted among full-time and distance learning students. Through the analysis of variance, the strength of the impact of each factor related to deviations in students’ health was determined. Statistical reliability was confirmed using variance and special tables. The conducted research identified informatively significant factors related to health deviations of distance learning students. The analysis of variance was used to assess the influence of factors and their strength. Reliability of the impact of factors was determined using variance and special tables. The results are reliable (p<0.001). The available literary sources do not cover the problem of ranking the leading factors. Among them, a decrease in physical activity, emerging sub-health forms, visual impairments, changes in the general psychoemotional state are of particular importance. The following conclusions can be done. The revealed features of health disorders in distance learning students are associated with a decrease in physical activity, the development of hypodynamia, emerging sub-health states, visual impairment, a change in the general psychoemotional state. The distance learning process shall be regulated by Sanitary Rules and Regulations developed for universities.

The paper analyzes the impact of the “model budget” on the problems of intergovernmental relations in the Russian Federation: a high proportion of expenditure obligations of regional and local budgets and a high degree of interregional inequality in fiscal capacity and socio-economic development. It was concluded that the planned broader use of the “model budget” will not solve the problem of unfunded mandates and will lead first to a significant reduction in incentives for regional authorities to develop the territorial revenue base, and then to economic slowdown in the country. As an alternative approach to improving intergovernmental relations, options are being considered for adjusting the parameters of the equalization transfers distribution formula, the procedure for determining their total volume and calculating the budget expenditure index. In solving the problem of unfunded mandates, an equally important role is given to the procedure for preparing a financial and economic rationale for draft laws.

The Impact

Introduction. Physical activity is known to be an important factor influencing health throughout human life. This issue has become crucial for public health due to the aging of the population in both developed and developing countries. Aim. is to present a literature review on the forms of physical activity undertaken by the elderly, as well as on issues related to physical activity and the population aging. Material and methods. The study was prepared on the basis of a review of Polish and foreign literature. The following databases and data sources were used: EBSCO, ScienceDirect and Google Scholar. An additional source of data were the websites of the Central Statistical Office. Strictly defined key phrases were used during the collection of literature. The work has been divided into thematic subsections on the aging of the society, the impact of physical activity on health and the main topic, i.e. forms of physical activity selected by the elderly. Analysis of the literature. The number of elderly people in Polish society has increased by almost 3.7 million over three decades. Therefore, an important topic is prophylaxis aimed at increasing the number of days in good health, largely covering the broadly understood activation of the elderly. The available data indicate that only 12% of elderly people undertake physical activity once a week. The most common form of spending free time actively is walking (as many as 73% of people in this population declare this form of physical activity in one of the presented studies). Conclusion. Organized forms of physical activity are undertaken much less frequently by the analyzed age group mainly due to financial limitations and limited availability of sports infrastructure.

AbstractIntroduction. The COVID-19 is the name of an infectious disease caused by a new strain of coronavirus SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2). It was first diagnosed in December 2019 in patients in Wuhan City, Hubei Province, China. The symptoms are dominated by features of respiratory tract infections, in some patients with a very severe course leading to respiratory failure and, in extreme cases to death. Due to the spread of the infection worldwide, the WHO declared a pandemic in March 2020.Aim. An investigation of the impact of social isolation introduced due to the coronavirus pandemic on selected aspects of life. The researchers focused on observing changes in habits related to physical activity and their connections with people’s subjective well-being and emotional state.Material and methods. The study was carried out within the international project of the group „IRG on COVID and exercise”. The research tool was a standardized questionnaire.Results. Based on the data collected and the analysis of the percentage results, it can be observed that the overwhelming majority of people taking up physical activity reported a better mood during the pandemic. However, statistical tests do not confirm these relationships due to the small sample size.Conclusions. Isolation favours physical activity. Future, in-depth studies, by enlarging the population group, are necessary to confirm the above observations.

Time Point

Background: Brief advice is recommended to increase physical activity (PA) within primary care. This study assessed change in PA levels and mental wellbeing after a motivational interviewing (MI) community-based PA intervention and the impact of signposting [SP] and Social Action [SA] (i.e. weekly group support) pathways. Methods: Participants (n=2084) took part in a community-based, primary care PA programme using MI techniques. Self-reported PA and mental wellbeing data were collected at baseline (following an initial 30-minute MI appointment), 12-weeks, six-months, and 12-months. Participants were assigned based upon the surgery they attended to the SP or SA pathway. Multilevel models were used to derive point estimates and 95%CIs for outcomes at each time point and change scores. Results: Participants increased PA and mental wellbeing at each follow-up time point through both participant pathways and with little difference between pathways. Retention was similar between pathways at 12-weeks, but the SP pathway retained more participants at six-months and 12-months. Conclusions: Both pathways produced similar improvements in PA and mental wellbeing, suggesting the effectiveness of MI based PA interventions. However, due to lower resources required yet similar effects, SP pathways are recommended over SA to support PA in primary care settings.
