Social Aspect of “Reverence for Life” Ethics by Albert Schweitzer
Authors: Gorbunov Svyatoslav Sergeevich
Published: December 2021

The aim of this work is to examine the moral imperative of “reverence for life” by Albert Schweitzer (1875-1965) in the context of the issue of its social or asocial character. The scientific originality of the research lies in the fact that the analysis carried out in it considers the ethics of “reverence for life” not in the context of a person’s attitude to other creatures or in general to the natural environment, but in the context of intrasocial relations. The results obtained show that the ethical imperative of reverence for life is both person-centred and socially-centred at the same time, which allows us to speak of the social (as opposed to asocial) character of Schweitzer’s ethics.

Authors: Gudymenko Yuri Yurievich
Published: December 2021

The aim of the study is to reconstruct the alignment of artistic forces in the Russian portrait genre “about 1820” based on reviews of the academic exhibition that opened that year. The scientific novelty of the research lies in the fact that for the first time the publications devoted to the exhibition are considered in aggregate, all the names of the Russian artists who worked in the portrait genre are touched upon. The article analyses the surviving works that were at the exhibition, as well as those that were not on display, but they most clearly characterize the creative work of famous and less known masters: D. I. Antonelli, A. G. Varnek, I. E. Yakovlev, M. N. Shamshin, as well as the graduates of the Academy M. T. Durnova, M. Gomion and others. The results of the study have shown that the exposition of 1820 was quite representative and, despite the absence of such masters as, for example, O. A. Kiprensky and V. L. Borovikovsky, objectively reflected the alignment of artistic forces in the portrait genre of that time.

Published: December 2021

Abstract: Obstructive sleep apnea/hypopnea syndrome (OSA) is a common condition that may lead to excessive daytime sleepiness, cognitive disturbance, and a decreased concentration that are associated with the risk of workplace accidents and injuries. It is difficult to diagnose OSA due to low severity and specificity of its symptoms and special requirements in respect of medical resources. We assumed that it would be more effective and cost-efficient to diagnose OSA in railway workers with such risk factors f coronary heart disease as arterial hypertension and metabolic disorders since this group receives comprehensive medical attention. However, no studies on the prevalence of OSA in railway workers specifically considered the risk factors for coronary artery disease. The aim of the study was to assess the prevalence of OSA in railway workers with confirmed cardiovascular and metabolic disorders that did not disqualify them from their job. Material and methods. The study included 967 railway workers (locomotive drivers and their assistants). On Stage 1, a group of participants suspected OSA was selected; and on Stage 2, a group of participants with confirmed OSA was formed. Polysomnography or cardiorespiratory monitoring were used to diagnose OSA. Results. We developed a two-step algorithm of OSA diagnosis that included a preliminary assessment of the probability of OSA. 236 (24.4%) participants with a probability of OSA were selected among the initial 967 persons with risk factors for coronary artery disease. Further assessment confirmed OSA in 141 (60%) participants in this group. The analysis of distribution of risk factors for coronary artery disease and OSA showed that 125 (53.0%) of patients with BMI ≥ 30 kg/m², 115 (48.7%) of patients with AH, and 26 (11.0%) of patients with type 2 diabetes had OSA; most of them had some combination of these risk factors. Conclusions: OSA is prevalent in the group of professionally active locomotive drivers and their assistants with risk factors for coronary heart disease; every second worker in a target group with BMI ≥ 30 kg/m², AH or with both risk factors was diagnosed with OSA. The proposed two-step algorithm with a pre-test assessment of OSA probability and subsequent instrumental examination (cardiorespiratory monitoring, polysomnography) allows to accurately diagnosis OSA and allocate medical resources in a cost-effective manner.

Abstract. Introduction. Improving the efficiency of the use of public resources and the quality of medical care provided in modern conditions is becoming one of the priority tasks of science and healthcare management. In industry and the service sector, different management methods are successfully applied. Lean production is considered one such example in healthcare. Lean production is a management concept based on an unswerving commitment to eliminating all types of waste, continuous improvement of processes, improvement of organization and working conditions. One of the central provisions of Lean production is the concept of value for a patient and a medical worker in the performance of a medical service [1]. In the Republic of Belarus in 2019 the implementation of the pilot project of the Ministry of Health of the Republic of Belarus "Caring Polyclinic" was started, which was based on the principles and tools of lean production. The goal of the pilot project is to increase the satisfaction of consumers of medical services with the quality and availability of medical care by optimizing business processes and eliminating losses. Research methods: the study presents a process of providing health care to the population, which can be improved based on the principles of lean production. Possible directions of using the accumulated material on the application of the principles of lean production in the healthcare system in the context of COVID-19 are considered [2]. Studied and analyzed the original publications containing information on the features of the organization of medical care in a lean production [3]. Results. The concept of lean production is able to solve the main problems of organizing the work of primary health care and demonstrates the effectiveness of this approach for optimizing the business processes of providing medical care. The use of leanproduction technologies in a polyclinic allows not only to increase the throughput of the institution, increase labor productivity, but also to ensure the quality of medical care, to increase the satisfaction of patients and employees. Conclusion. The use of the principles and tools of lean production in healthcare provides an increase in the productivity and efficiency of medical workers, optimization of work processes, which leads to a reduction in the waiting time for patient services and a reduction in the duration of patient treatment, respectively, to improve the quality of medical care, reduce costs, and increase patient and employee satisfaction.

Abstract: A statistical analysis of stabilometric study results of 50 male patients with vibration disease (VD) from the effects of general vibration (GV) (average work experience 26,7±6,2) has been carried out. The control group (CG) included 50 men who have not been exposed to the general vibration. The compared groups were comparable by age: the average age of patients with vibration disease was 56.34+5.15, patients of the control group-58.22+-7.05. The study of the support symmetry and equilibrium function was carried out using the Romberg test on the St-150 stabiloplatform (Biomera, Moscow) in a vertical stand with European installation of feet in the positions of open (OE) and closed eyes (CE). A comparative analysis of the parameters of support symmetry in patients with VD from GV revealed a statistically significant sagittal asymmetry in the phases of OE and CE than in individuals of CG. Among the balancing parameters, the most informative parameters of computer stabilometry in patients with VD from GV were: an increase in the area of the statokinesiogram, a decrease in energy efficiency in both phases of the study, and an increase in the speed of the statokinesiogram in phase with CE. Computer stabilometry can be recommended as an additional objective research method in the diagnosis of early stages of VD from GV to improve the quality of periodic medical examinations.

Abstract: The relationship between the level of health of an employee and his professional reliability is currently obvious and does not require additional evidence. The implementation of measures aimed at reducing the risks of developing emergency situations due to the human factor at nuclear energy use facilities is an important element of the radiation protection system. In order to achieve the above-mentioned goals, in accordance with Federal Law № 170-FZ of 21.11.1995, the performance of certain types of work in the field of nuclear energy use requires special permits from Rostechnadzor. A prerequisite for obtaining such a permit for a specialist is the absence of psychophysiological contraindications based on the results of a psychophysiological examination. This study analyzes the results of psychophysiological examinations of employees of nuclear energy use facilities conducted by specialists of the SRC-FMBC in 2020.

Abstract: The negative side of the high rate of development of the electric power industry is the increase in the influence of electromagnetic radiation on humans. Unlike an electric field, a magnetic field is not shielded by personal protective equipment. Personnel exposed to industrial frequency magnetic fields are exposed to the negative effects of radiation on the nervous, cardiovascular, immune, and endocrine systems. Objective: to study and analyze the prevalence of diseases of the endocrine and cardiovascular systems in workers employed in the electric power industry. Materials and methods: 598 employees of the electric power industry were examined. The analysis of the survey data was carried out on the basis of descriptive statistics (relative values (%), the number of cases (n)) using the Microsoft Office Excel 2016 software package. Results: out of 598 men, 29.8% were obese, 16.7% had cardiovascular diseases and 2.7% had type 2 diabetes. The structure of morbidity by seniority groups was also analyzed and the dependence of the prevalence of morbidity on the length of service was revealed. Conclusion: the analysis of the obtained data indicates a high prevalence of diseases of the cardiovascular system and obesity among employees of the electric power industry exposed to industrial frequency magnetic fields.
