The author presents the results of a comprehensive assessment of working conditions and functional systems of the body of workers in the conditions of by-product coke production. Harmful factors of the working environment negatively impacting on the health indicators of workers, which is reflected in the high values of morbidity with temporary disability. Quantitative criteria for identifying risk groups and disability were determined depending on the professional group, work experience, gender and age. To calculate the risk range, the method of rationing of intensive indicators was used, which makes it possible to assess the effect of production on the morbidity of workers, as well as to use the results obtained for a comprehensive integral assessment of the likelihood of the risk of disability in the studied professional groups. Ranges of risk have been obtained, which will help to identify "risk groups" among workers requiring examination and preventive measures. Equations of multiple regressions for complex integral risk assessment are obtained, risk forecast for the studied professional groups is calculated. The developed mathematical model and equations of multiple regressions make it possible to calculate the stress levels of the functional systems of the body, to quickly assess the performance of a person both at the time of examination and in production conditions. The proposed method for assessing the impact of working conditions on health indicators can be used at mining enterprises when certifying workplaces and assessing working conditions. The developed methodological recommendations are used in the educational process to improve the quality of scientific research, to analyze the results obtained, as well as in production to simplify the procedure for assessing the impact of harmful production factors on workers and the scientific organization of labor.

The Impact

Introduction. Teacher’s health problems depend on many factors. However, research has focused on psychological stressors. The goal is to assess the factors of the school environment and determine the impact of seniority and the level of academic load on the health status of secondary school teachers. Material and methods. Assessment of working conditions of teachers was studied on hygienic characteristics and their research in 11 schools. There were studied conditions of the school environment (microclimate, lighting) and the timing of the teachers’ labor process. A clinical and psychological examination of 53 women with an average age of 50.0 (44.0-59.0) years, work experience - 27.0 (19.0-34.0), load - 25.0 (21.0-32.0) hours per week. According to the indices of harmfulness and danger of factors of the working environment, the severity and intensity of the labor process, the class of working conditions in only 25% of the examined corresponded to the permissible class. The frequency of increased irritability, hypertension, emotional exhaustion, reduced stress resistance is higher in the group of teachers with experience of 20 years or more. Discussion. Teachers of secondary general education are exposed not only to occupational stress, but also to the effects of the negative conditions of the school environment and the labor process. Conclusions. Targeted studies of the conditions of the school environment, factors of the educational process must be carried out to identify their impact on the health status of teachers.

Introduction. Professional groups of railway workers engaged in the repair of wagons are directly responsible for the safety of railway traffic. The analysis of literature testifies to insufficient attention of researchers to the hygienic problems associated with labor activity of workers of wagon-repair production.The aim of the study is to assess the occupational risk to the health of wagon repair workers, due to the impact on them of factors of the working environment and the labor process.Materials and methods. The study used comprehensive hygienic studies using the methodology of occupational risk to worker’s health.Results. The leading factors of the working environment (class of working conditions 3.2–3.4), which are exposed to workers depending on the specifics of the work performed. Identified professional groups with medium (significant) high (unbearable) and very high (intolerable) category of a priori occupational risk: in wagon meintenance workshop — 17 groups (94% of jobs), in a wagon assembly workshop — 11 groups (80% jobs), in wagon wheel workshop — 3 group (100% jobs). At the same time, according to the request for medical care, employees were diagnosed with isolated cases of occupational diseases.The levels of morbidity with temporary disability of employees of the main workshops are statistically significant (p<0.05) higher than those of the control group in 1.4–1.9 times. The influence of the complex of chemical factors of low and medium intensity on the levels of morbidity of respiratory diseases in the group of workers of the wagon wheel workshop, which were 1.7–2.0 times higher than in the control group, is confirmed by the average degree of causation of the production condition of this pathology (RR=1.7; EF=42.0%).The combined effect of vibration and severity of the labor process forms a high level of temporary disability of employees of the main workshops in connection with diseases of the musculoskeletal system, which was 2.7–4.4 times higher than in the control group, and also determines the prevalence of this pathology in the structure of diseases detected on medical examinations (23.2%). Diseases of the musculoskeletal system are caused by the production of employees of the wagon meintenance workshop (RR=3,9; EF=74,9%), as the most unfavorable in terms of hygiene on these factors.The stressful influence of the complex of harmful production factors on the health of wagon repair workers is manifested by the high risk of diseases of the cardiovascular system, gastrointestinal tract, neurological disorders, violation of adaptation of the cardiovascular system in 97% of the examined, as well as the predominance of diseases of the digestive system and circulatory system detected on periodic medical examinations.Conclusions. Harmful working conditions (class 3.1–3.4) cause the suspected occupational risk from small (moderate) to very high (intolerable) to 100% of the jobs of wagon repair workers. The results of the study of morbidity and risk of pathology indicate a significant risk of damage to the health of workers.

Introduction. Adverse effects of environmental factors can cause dysfunction of organs and systems, hormonal dysfunction, genetic disorders, which can adversely affect the health of future generations. The aim is to study occupational risk factors and assess their impact on the health of male workers of machine-building enterprises, to develop preventive measures. Material and methods. The working conditions of 318 male workers of the main professions of the machine-building enterprise (miller, locksmith, electric and gas welder, turner, caster, etc.), having occupational contact with harmful occupational factors, were studied in comparison with 148 employees of the control group. Epidemiological, socio-hygienic, statistical and risk calculation methods were used. Results. 68.2% of respondents were found to have occupational contact with cutting fluid, 24.3% contact with chemicals, 14.4% - with heavy metals, 66.2% of respondents work in conditions of noise exposure, 40.1% - local vibration, 22.3% - in conditions of hypothermia, 14.4% - in conditions of overheating. Excess of maximum permissible concentrations of benzo(a)pyrene, aerosols of mineral oils, epichlorohydrin was detected in the air of the working zone. At workplaces, there were excess levels of noise, general vibration, thermal radiation. The impact of harmful occupational factors in the workplace was established to create a high risk to the health of workers. Conclusion. Working conditions of workers of the machine-building enterprise are mainly estimated as harmful. Critical organs and systems for the development of occupational pathology were identified, the high carcinogenic risk from exposure to benzo(a)pyrene was revealed. Employees of the machine-building enterprise were shown to have a high risk of oncology, respiratory diseases, central nervous system diseases, pathology in offspring. As a result, risk groups were formed and targeted preventive measures were proposed, including monitoring of the health status of high-risk groups, occupational selection, and medical examinations.

Introduction. At present, the patterns of changes in the levels of biomarkers and the relationship of changes in their values with the pathogenesis of diseases caused by the impact of adverse factors of labour activity are not sufficiently studied. The most unresolved issues are the choice of informative laboratory indicators and diagnostic test systems in investigating the impact of physical factors on the working environment (vibration and physical overload) neurohumoral regulation: pituitary-adrenal pituitary-thyroid, pituitary-gonadal system and hormonal indicators of carbohydrate metabolism. The aim of the study was to determine diagnostic hormonal markers and integral indices to identify early changes in the neurohumoral status in the body of workers under the influence of working environment factors. Materials and methods. 330 workers of mining and machine-building enterprises were examined. Of these, 128 people with vibration disease, 45 people - with lumbosacral radiculopathy, combined pathology (vibration disease and lumbosacral radiculopathy) was detected in 60 persons. The preclinical stage (initial signs of diseases) was noted in 97 workers. Laboratory studies included hormones and integral indices of the pituitary-adrenal, pituitary-thyroid, pituitary-gonadal system, carbohydrate metabolism. To select the diagnostic significance of laboratory biomarkers, diagnostic sensitivity, prenosological value, pathognomonicity, direction, severity, and selectivity of changes in biomarker levels were evaluated. Results. The combined effect of vibration and physical overload on the body of workers was found to have a unidirectional and systemic impact on the levels of hormones of the pituitary-adrenal, pituitary-thyroid and pituitary-gonadal systems, increases insulin resistance. The severity of changes in neurohumoral regulation indicators depends on the nature and severity of the occupational neurological disease. The highest diagnostic sensitivity (Df = 72-74%) in vibration disease and its combination with lumbosacral radiculopathy was obtained for pituitary-gonadal hormones and indicators of insulin resistance. The lowest values of Dh are typical for the hormones of the pituitary-thyroid system (no more than 14%). To identify early changes in neurohumoral regulation in the body under the influence of vibration and physical exertion, it is most informative to determine the concentration of total testosterone, luteinizing hormone and insulin, as well as the integral pituitary-adrenal index, insulin resistance indices. To identify hidden disorders of the pituitary-thyroid system, the definition of the essential thyroid index can be used. Discussion. The results obtained allowed us to assess the nature of changes in the levels of hormones of the pituitary-adrenal, pituitary-thyroid and pituitary-gonadal systems and carbohydrate metabolism and to propose informative laboratory biomarkers reflecting early changes in neurohumoral regulation under the influence of physical factors of the working environment. Conclusions. To identify early changes in neurohumoral regulation in the body of workers under the influence of vibration and physical exertion, the most informative is the determination of the concentration of total testosterone, luteinizing hormone and insulin, the integral pituitary-adrenal index, and insulin resistance indices. To identify hidden disorders of the pituitary-thyroid system, the definition of the integral thyroid index can be used.

COVID-19 нанес серьезный удар по системам здравоохранения многих стран мира, включая Республику Казахстан. Чтобы справиться с пандемией, Казахстан разработал план, содержащий три стратегические цели: 1) предотвращение вспышки болезни; 2) Обеспечение оптимального ухода для всех пациентов и 3) Сведение к минимуму воздействия пандемии на системы здравоохранения, социальные услуги и экономическую деятельность. Однако неравномерное распределение финансовых ресурсов по регионам, нерегулярное потребление медицинских услуг и различия в показателях здоровья препятствуют этим усилиям. Другие проблемы - это нехватка медицинских сил, неожиданность ситуации, отсутствие знаний о коронавирусной инфекции и бессилие перед этой новой болезнью. Были трудности с массовым тестированием, поскольку стигма и страх перед карантином вынуждали людей не проходить тестирование. После отмены чрезвычайного положения и строгой изоляции страну охватила эйфория, которая привела к резкому увеличению числа случаев заболевания. Чтобы взять ситуацию под контроль в июне 2020 года был экстренно введен второй локдаун, постепенно стало уменьшаться количество больных и инфицированных. Пандемия показала, насколько хрупка и зависима система: была отложена плановая вакцинация детям до 1 года, временно приостановлено медицинское обследование и оказание медицинских услуг больным хроническими, онкологическими заболеваниями, плановая госпитализация. Многие врачи и медсестры заразились и заболели. На момент написания этой статьи эпидемиологическая ситуация в стране с COVID-19 находится под контролем и надзором, однако давать какие-либо прогнозы относительно его завершения пока рано. Казахстан готовится к вакцинации от коронавирусной инфекции, в первую очередь вакцинации должны подвергаться группы риска, медицинские и социальные работники, а также люди с хроническими заболеваниями. Пока коллективный иммунитет не сформирован, казахстанцы должны проявлять осторожность при снятии ограничений, чтобы предотвратить взрыв новых случаев заболевания. COVID-19 has strained the healthcare systems of many countries worldwide including the Republic of Kazakhstan. To cope with the pandemic, Kazakhstan mounted a plan containing three strategic objectives: 1) Preventing the outbreak of the disease; 2) Ensuring optimal care for all patients, and 3) Minimizing the impact of the pandemic on health systems, social services, and economic activities. However, the uneven distribution of financial resources across regions, irregular consumption of medical services, and inconsistent health indicators hamper these efforts. Other issues are the lack of medical forces, the unexpectedness of the situation, lack of knowledge on coronavirus infection, and powerlessness in front of this new disease. There were difficulties in mass testing as stigma and fear from quarantine forced people not to get tested. The euphoria enveloped the country after abolishing the emergency state after an intense lockdown which resulted in increased cases. A second lockdown was urgently introduced in June 2020 to take control of the situation. The number of patients and those infected gradually began to decline. The pandemic showed the fragility and inter-dependence of the health system- planned vaccinations against many infectious diseases were postponed. Medical examination and provision of medical services to patients with chronic, oncological diseases, planned hospitalization were temporarily halted. Many doctors and nurses became infected and ill. The country's COVID-19 epidemiological situation is somewhat under the control and supervision as of this writing. However, to give any forecasts for its completion is still too early. Kazakhstan is preparing to vaccinate against coronavirus infection. First of all, risk groups, medical and social workers, and people with chronic diseases should be subject to vaccination. Until herd immunity is not formed, Kazakhstanis must keep caution when the restrictions are taken off to prevent an explosion of new disease cases.

Introduction. Working conditions of the teaching staff of higher education institutions are not static, as they reflect the changes taking place in the outside world. The increase in the role of informatization, the acceleration of the information flow, the changing of the information field, the introduction of scientometric indicators, the recognition of the impact of stress in the workplace on the health of an employee – all this accompanies the work of the teaching staff. The analysis of these phenomena makes it possible to single out three large groups of working conditions for the teaching staff of higher education institution, which today are undergoing changes, to identify the prerequisites for their occurrence and to formulate their consequences for the entire educational process. The purpose of the study was to conduct a comprehensive analysis of the working conditions of higher education teachers, which are currently undergoing changes. Methods and methodology. The work used the methodology of a comprehensive study, including methods of document analysis, comparative analysis, secondary use of sociological, economic and medical data. The results of the study show that the digitalization of vocational education, including higher education, is carried out in different conditions than the digitalization of schools, which leads to the emergence of a new paradigm of interaction between higher education teachers and students. As a result of research, the absence of a centralized acquisition of skills in the use of digital technologies by teachers was confirmed: 45% of respondents carry out advanced training on their own, 41% – using online platforms, 31% – ask for help from colleagues in their educational institution, 30% – exchange experience with colleagues from others vocational institutions. In the absence of legislative regulation of the issue of mastering new digital competencies by the teaching staff of higher education institutions, the ways of solving this issue are proposed. The results of the research revealed that meeting the scientific productivity requirements for the teaching staff is one of the main sources of stress in the workplace (40% of respondents). It is concluded that in order to achieve quality indicators in the field of scientific activity, in order to prevent opportunistic behavior of the teaching staff, higher education institutions need to develop tools of internal motivation. The authors believe that an integrated approach to regulating the emotional burnout of teachers could also be applied in relation to minimizing the risks of professional burnout, that is, to adopt acts of legal regulation at the federal and local levels in order to prevent professional burnout.

The department of Physiology began its work in October 1961 with the establishment of the Faculty of Medicine. In the first years of its existence, the deparment encountered numerous functioning and organisational difficulties due to the limited space available on location at the time, as is often the case for newly set scientific and educational institutions. However, thanks to the efforts of competent state institutions, scientific research could eventually focus on three main issues: a) Homeostasis in the body, b) Cardio-respiratory functional systems and their adaptation to different models of weight loads (in order to investigate the influence of dosed loads on histophysiological characteristics of muscles, especially on the state of mitochondrial apparatus, researches were conducted on laboratory animals), c) The neurophysiological laboratory especially focused on changes of spontaneous bioelectric activity of different brain structures in terms of the formation of functional systems of behavior. The microelectrode technique of registration of activity of individual neurons that are part of different brain structures was used for the first time. This allowed to investigate the characteristics of individual neurons of the sea slug Aplysia depilans. In the Department of Physiology, researchers' attention was drawn to an orientation-questioning reaction, as a fundamental biological reaction. In addition to the vegetative and electroencephalographic parameters of the mentioned reaction, a special interest was allocated to the neural and neurochemical characteristics of certain brain structures during that reaction. To this end, microelectrode and microiontophoretic examinations of activity of single neurons in various structures of the brain were conducted on laboratory animals. In the middle of the 20th Century, the impact of artificial electromagnetic fields on biological systems was considered as a serious setback. This resulted in the conduction of extensive researches on the effects of these fields on biological systems.

The work presents data analysis of the results of special assessment of working conditions for workers of various branches of economy in the Bashkortostan Republic. Results of special assessment of working conditions (SAWC) and medical examinations were used for the analysis. It is noted, that some professional groups, for example, persons performing their work in the sphere of agriculture, have no exposure to the biological factor. Construction workers were not exposed to industrial vibration, while the noise level for half of the analyzed cases was of class 2.0, although in most cases, industrial noise and vibration have single source. Proportion of facilities that revealed a discrepancy between levels of harmful industrial factors and requirements of sanitary legislation remains high. The greatest share of objects does not correspond to sanitary and epidemiological requirements according to the chemical and physical factor. At the moment, SAWC does not fully reflect the working conditions of employees in different sectors of production. Underestimation of its influence on working conditions of workers is typical for a considerable number of professional groups and individual jobs. Analysis on the basis of SAWC is not sufficient for a hygienic assessment of the impact of production environment factors and labour process on health and requires comprehensive assessment methods.

Aim: Is to study the role of water in the life of students and to investigate the impact of its quality on the health of students who did sports. Materials and Methods: The study was conducted at Polissya National University (Zhytomyr, Ukraine) in 2018-2020. Thus, 509 students between the ages of 17 and 23 who did not do sports and 317 student-athletes were surveyed. The level of students’ health was examined according to the methodology of G.L. Apanasenko. Results: It was found that the majority of students who did not do sport (97.5% of males and 96.7% of females) did not stick to the water consumption schedule, while 50.8% of males and 52.2% of females who did sport followed strict norms of the water consumption schedule to maintain water balance. According to most health indicators, students-athletes had better average values of the studied indicators than those students did not do sport. Conclusions: Water plays an important role in the lives of students and especially those students who do sport. High-quality water, sticking to water consumption schedule, especially during prolonged physical exercise and at high temperatures have a positive effect on the body and improve the health of students.

This chapter presents a qualitative study that was conducted to investigate the implementation and outcomes of recent child protection reform in Israel. Using the ‘systems approach’ as conceptual framework allowed to understand the impact of the working conditions on every-day child protection practices. The key finding of the research – that the reform’s aims of strengthening practice and improving the safety and well-being of vulnerable children have not been entirely achieved – is explained by the organisational working environment and culture acting as barriers to the expected change. Findings touch on in particular: heavy workloads and an organisational culture that seeks opportunities to shortcut procedures and processes; inadequate professional supervision and support; insufficient training and qualifications; and lack of strong organisational leadership. It is concluded that organisations’ underlying problems need to be resolved if effective delivery of services for children and families is to be achieved.
