The relevance of the study is determined by the fact that the professional competence of a teacher constitutes a dynamic combination of knowledge, abilities and practical skills, ways of thinking, professional, ideological and civic qualities, moral and ethical values. The linguistic competence of the teacher depends entirely on the possibilities of professional growth and the dynamics of the development of professional and communicative competences. The novelty of the study is determined by the fact that in professional activity the teacher acts as an active subject of communication: transmits and accepts information from students, colleagues and parents, strives for the maximum realisation of the abilities of each student and ensuring their emotional comfort. The authors of this study have determined that one of the primary tasks of higher pedagogical education lies in the development of professional and pedagogical communicative competence of a teacher. The practical significance of the study is determined by the fact that professional and pedagogical communicative competence acts as a spiritual and moral factor and the scientific content of the educational process, where a major role is played by the teacher's knowledge, humanity, spiritual generosity, as well as the desire to understand and help the student.
Introduction. Health care workers are at risk of infection with the SARS-CoV-2 virus. However, many aspects of the professionally conditioned COVID-19 are still poorly understood. The aim of study is to conduct a brief review and analysis of scientific data on the prevalence, features of clinical and laboratory COVID-19 syndromes in medical professionals. To evaluate the structure of post-COVID syndrome in health care workers who are observed in a large multidisciplinary medical organization that has a center for occupational pathology. To present the current state of the problem of examination of the connection of COVID-19 with the profession and admission to work in conditions of high risk of SARS-CoV-2 infection. Materials and methods. At the first stage, a brief review of the literature on the problem of COVID-19 in health care workers was performed, at the second - a single-center observational prospective study of COVID-19 convalescents. The main group consisted of health care workers (n=203), the comparison group - people who do not have occupational health risks (n=156). The groups were comparable in demographic characteristics. The work experience of the medical staff was 15 (5; 21) years. Of the participants in the main group, 20.2% worked in hospitals, and 79.8% in outpatient institutions. Three of the participants (1.5%) were employees of specialized COVID hospitals. Doctors were 25.6%, secondary medical personnel - 51.7%, junior medical and technical personnel - 22.7%. A severe form of COVID-19 was suffered by 25 (12.3%) people, after the artificial ventilation of the lungs (AVL) - two participants. The observation time is 60 days. Statistical analysis included standard methods of descriptive statistics, determination of relationships by the method of logistic regression. The significance level is p<0.05. Results. Most of the known data on COVID-19 in health care workers is obtained in cross-sectional studies. The possibility of occupational infection has been sufficiently proven. The risk probably depends on the work performed and is higher in conditions of direct contact of medical personnel with adults, potentially infected patients, but not in a specialized hospital. It is possible that the course of COVID-19 in health care workers differs from the general population of patients there is evidence of a greater frequency of weakness and myalgia. Studies of the features of post-COVID syndrome in health care workers in available sources could not be identified. According to the results of their own research, health care workers who had experienced COVID-19 had a higher frequency of central thermoregulation disorders, arrhythmias, heart failure, panic attacks and depression. Conclusions. Health care workers are at risk of COVID-19. Professionally conditioned post-COVID syndrome is characterized by the frequency of violations of the central mechanisms of thermoregulation and arrhythmias. COVID-19 in health care workers meets the definition of occupational disease.
Slow-extinguishing lime is used in the production of autoclave hardening aerated concrete. If the production of aerated concrete is arranged in parallel with the production of silicate brick, then the lime will be quick-extinguishing. In this connection, the present paper considers the possibility of using quick-extinguishing lime and waste products from silicate brick. A significant content of quartz (over 75%) in the composition of silicate brick makes it possible to use it in a ground form as an analogue of ground sand. Also, the paper has established a reduction in the setting time of cement and an increase in the strength of autoclaved concrete. However, slip-like additives reduce the mobility of the mixture and increase its water demand. The deterioration of processing characteristics is observed when ground waste is introduced into the sand slurry of aerated concrete mixture. Therefore, a complex additive based on the waste of silicate brick, plasticizer and gypsum stone has been proposed, which allows for expanding the scope of application of quick-extinguishing lime, reducing the water demand of the mixture without reducing mobility and increasing the strength of the finished product.
The development of modern computer technologies has made it possible to introduce into orthodontic practice the latest methods of diagnosis and treatment of dentoalveolar anomalies. Domestic orthodontics, which has an extensive scientific base, has received the opportunity for technological development since the beginning of the 90s. The Department of Orthodontics Moscow State University of Medicine and Dentistry named after A.I. Evdokimov of the Ministry of Health of Russia (Moscow, Russia), throughout its scientific experience, under the guidance of Corresponding Member of the Russian Academy of Medical Sciences, Doctor of Medical Sciences, Professor L.S. Persina, uses modern diagnostic methods in her diagnostic arsenal to analyze the morphological state of the dentition.
