Introduction. Healthcare workers are at a high risk of emotional burnout due to their professional activities associated with constant mental and intellectual stress. The importance of timely diagnosed psychoemotional burnout syndrome (PEBS) determines the need to develop measures for its prevention. Material and methods. We have studied the working conditions, health status of healthcare workers; the indices of relative risk and etiological component of the contribution of work environment and the work process factors to the development of the identified pathology were calculated; the probability of the development of PEBS based on diagnostics of the emotional burnout level according to the method suggested by V.V. Boiko. Results. During occupational activities healthcare workers are exposed to chemical, biological, physical work environment factors, the severity and intensity of the work process. Indices of the work process intensity are assigned to the leading hazardous occupational factor according to which the class of working conditions is determined as hazardous Class 1-3. PEBS, diseases of the musculoskeletal, circulatory, digestive and respiration systems are classified as work-related ones. An assessment of the possibility of the development of PEBS has shown 35% of the healthcare workers to consider working conditions to be related to PEBS. The dependence of the development of somatic diseases on the presence or absence of PEBS is revealed. Conclusion. The working conditions of healthcare workers are characterized by the impact of a complex of occupational factors, the leading of which is the work process intensity. Diseases of the musculoskeletal system, circulatory and respiration systems, psycho-emotional burnout syndrome are classified as work-related diseases with a high degree of conditionality. The criteria for evaluating the effectiveness of preventive measures are the reduction of general, work-related and occupational morbidity, the preservation of psychosomatic well-being, and the prevention of economic damage from temporary and permanent disability.
In the collective author’s work on the basis of general scientific methodological approaches, the revolutionary transformation of modern civilization into the format of a post-industrial state and network thinking under the influence of information technologies is considered, taking into account the relevance of awareness of threats to humanity during the convergence of digitalization into everyday reality. The main approach is a theoretical analysis of the impact of modern information technologies and their extrapolation to the near future of civilization from the point of view of the feasibility of creating favorable conditions for life, human improvement from the standpoint of improving moral, ethical, psychological and intellectual qualities. The results, which were obtained, can be used from the position of an interdisciplinary approach as a subjective scientific position of the authors of the article on the evolution of the post-industrial society and the assessment of possible variations in the development of the post-industrial economy on the platform of information technologies, which are part of the convergent ones that form the basis of the VI technological order of the IV industrial revolution. The authors explain that the reasoning given in the article isn’t a dogma and can be transformed directly by the spokesmen of these opinions and by other authors of other works on the topic of post-industrial development in the process of scientific discussions.
The article presents the results of complex hygienic and physiological studies of conditions of labor of workers of chemical industry. The age and seniority determinacy of health disorders. The alterations of cardio-vascular, nervous systems, ENT-organs, musculoskeletal system and connective tissue are established. In workers of main group unidirectional alterations are established concerning indices of peripheral blood characterized by anemic syndrome, neutrophil leukocytosis, lymphocytosis, eosinophilia and expressed thrombocytopenia.
Цель. Определить региональные особенности пыльцевого спектра воздушной среды г. Самары по итогам пятилетнего мониторинга, составление календаря пыления аллергенных растений для г. Самары. Материалы и методы. Пыльцу улавливали волюметрическим методом с использованием ловушки-импактора оригинальной конструкции на предметные стекла, покрытые смесью вазелина и воска. В полученных препаратах подсчитывали пыльцевые зерна и определяли их принадлежность к различным систематическим группам. Результаты. В 2013 г. в воздушном бассейне г. Самары зарегистрирован 21 таксон (12 древесных и 9 травянистых), в 2014 г. отмечено 20 таксонов (13 древесных и 7 травянистых), в 2015 г. - 20 таксонов (12 древесных и 8 травянистых), в 2016 г. - 21 таксон (13 древесных и 8 травянистых), в 2017 г. - 18 таксонов (10 древесных и 8 травянистых). Суммарно за исследуемый период (5 лет) доминировала пыльца амброзии (24,3), тополя (12), березы (11,5), сосновых (7,5), вяза (6,3), клена (6,3), крапивы (5,8), злаков (4,7), полыни (3,7). Определено 10 доминирующих таксонов, которые формировали от 90 до 95 ежегодного объема пыления. Преобладающие таксоны значительно варьировали год от года по удельному весу. только три вида пыльцы присутствовало в спектре ежегодно в количестве более 4 от годовой суммы: пыльцевые зерна тополя, березы и амброзии. Заключение. Выявлены региональные особенности аэропалинологической ситуации, характерной для региона, составлен календарь пыления аллергенных растений для г. Самары.Aim. To determine the regional characteristics of the pollen spectrum of the air environment by the end of the five-year monitoring to create the pollen calendar of allergenic plants in Samara, Russia. Materials and methods. Pollen was sampled using the volumetric method with a self-engineered pollen impactor into glass slides, covered with a mixture of petrolatum and wax. The pollen grains were counted and classified according to the systematic groups. Results. IIn 2013 the Samara urban air basin contained pollen of 21 taxa (12 woody taxa and 9 herbaceous taxa) in 2014 - 20 taxa (13 woody and 7 herbaceous) in 2015 - 20 taxa (12 woody and 8 herbaceous) in 2016 - 21 taxa (13 woody and 8 herbaceous) in 2017 - 18 taxa (10 woody and 8 herbaceous). During the five-year survey the dominant taxa were ragweed (24.3), poplar (12,0), birch (11.5), pine (7.5), maple (6.3), elm (6.3), nettle (5.8), willow (4.8), Gramineae (4.7), and wormwood (3.7). 10 dominant taxa were determined, which formed from 90 to 95 of the annual pollen volume. The prevailing taxa varied considerably from year to year by specific weight. Only three pollen species were present in the spectrum annually in the amount of more than 4 of the annual amount: poplar, birch and ambrosia pollen grains. Conclusion. Regional features of aeropalynological situation was revealed and pollen calendar of allergenic plants in Samara was created.
The article presents a method for the automated calculation of the magnitude of the efforts in the means of securing cargo fixed to the rolling stock in accordance with the Technical Conditions for Stowing and Securing Cargo in Wagons and Containers - a regulatory document of JSC Russian Railways (hereinafter referred to as TU). The method provides for all possible factors of the influence of the forces acting on the transported cargo as a result of its movement from the point of loading to the point of unloading, including the necessary technological operations performed along the route, using the example of a cargo with a flat base using the capabilities of the computing environment. The obtained research results are supposed to be used by shippers in the development of the optimal method for placing and securing transported goods on the rolling stock. The automated calculation method will allow obtaining the predicted value of the cargo shift value both along and across the car from the total effect of longitudinal, transverse and vertical forces acting on the cargo along the way. These values make it possible to optimally determine the place of installation of thrust bars on the car floor, depending on the geometric parameters of the transported cargo and the chosen method of fastening it to the rolling stock.
