Today, there are personal protective equipment, which due to their weight and size characteristics and design features can aggravate professional activity. This is characterized by an increase in the load on several major systems of the employee's body, including the cardiorespiratory system, which can cause the development of occupational pathology. The study of the functions of the cardiorespiratory system of humans in the process of his work is an important task in biomedical tests such as PPE, aggravating their professional activities and future means of individual protection from heavy labor and industrial exoskeletons. The aim of the study is to determine the possibility of using ergospirometry for the physiological assessment of personal protective equipment and industrial exoskeletons. Main part. In medical practice and high-performance sports, ergospirometry is considered the "gold standard" for functional assessment of the cardiorespiratory system. There are very few studies showing the use of ergospirometry for the purpose of physiological assessment of personal protective equipment. Results of research works in which ergospirometry was used in medicine, sports, as well as on the physiological and hygienic assessment of combat equipment, various types of personal protective equipment, including new promising personal protective equipment of the musculoskeletal system-industrial exoskeletons. The use of ergospirometry made it possible to register the main indicators of the human cardiorespiratory system both in field and laboratory conditions and allowed forming an objective conclusion about the dynamics of the degree of stress of the human cardiorespiratory system when using personal protective equipment and industrial exoskeletons with various weight and size characteristics.

Toxic Reactions

Formaldehyde (FA) is commonly used in cadaver fixation for years. FA vapors are released during the dissection process and macroscopic study of preserved anatomical pieces, raising their concentration in the Anatomy laboratory, causing greater exposure for students and teachers. Therefore, the objective of this study was to investigate toxic reactions in 37 students, through a questionnaire, produced by exposure to FA used for preservation of cadaveric material used in Anatomy, Morphofunctional Department, Faculdades Integradas de Patos (FIP), Brazil. Of the 37 interviewees, 26 (70.3%) were affected by the unpleasant and irritating smell of FA, 10 (27%) had no problems, and 1 (2.7%) did not tolerate an irritation produced by FA, ​​not participating in the laboratory practical classes. Exposure to FA was followed by several symptoms: excessive lacrimation (54%), itchy eyes (48.5%), redness of the eyes (40.6%), coryza or congested nose (35.2%) and respiratory distress (29.7%), with persistent symptoms during the permanence in the laboratory for 32.5% of the students. All students wear a lab coat for individual protection. However, only 8% used mascara and did not wear glasses, increasing the risk of contamination. Medical schools should encourage the use of Personal Protective Equipment (PPE) for the manipulation of FA, ensuring the protection of students and teachers in the Anatomy laboratory. Besides finding alternatives for the replacement of FA in the conservation of corpses.

Тhis study was conducted to determine, outline the main characteristics of improvement of psychological-pedagogical basis of the concepts of «profile-oriented school», «profile-oriented school in foreign languages» at secondary pedagogical educational institutions and institutions of higher education. The author investigated, analyzed the leading role and conceptual impact of the profile-oriented direction of education in the training of future highly qualified professionals in the field of pedagogical education of foreign language. It was noted that profile teaching of a foreign language is a purposeful training of students for further educational and / or professional activities related to the use of a foreign language as an object of future (professional) activity or as a means of professional communication. Today, school profiling is one of the important directions of modernization of Ukrainian general education system. The author analyzed the following principles of specialized education in a specialized school of a foreign language, which, according to the author, play the greatest role: the principle of social balance; the principle of continuity and continuity; the principle of flexibility, the principle of variability; the principle of diagnostic and prognostic feasibility, the principle of differentiation; the principle of individualization. The model of profile-oriented studying in foreign language has not yet been implemented in the practice of the school in full. Teachers work to create a logistical, methodological and didactic base of the model. Work plans of circles, mini-textbooks, electronic manuals, other materials are developed. Therefore, the integration of profile – oriented studying will maximize the continuous studying of both students and teachers and achieve high performance. We understand that our observation is only part of the research program we have created for this issue. Further studies we see in the analysis of the practical-methodical system of profile-oriented studying of future teacher of foreign languages.

Personal protective equipment has become the last line of protection for medical personnel during the pandemic of the new coronavirus infection since it allows minimizing risks of biological contagion. Given the existing staffing shortage, medical workers have to spend from 4 to 12 hours a day in the “red zone” where they necessarily wear personal protective equipment. Protective clothing is known to produce negative effects on functional state of the body and personnel’s working capacities. Assessment of up-to-date protective suits will allow developing recommendations on their suitable application bearing in mind a balance between necessary protection, providing favorable ergonomics, and reducing risks of adverse effects on functional state and working capacities. Our research aim was to hygienically assess health risks for medical workers who had to wear reusable protective suits. Our research object was a reusable suit made from polyether fabric with polyurethane membrane coating and antistatic threads. We performed an experiment aimed at evaluating thermal state of the body, psychophysiological state, and responses by the volunteers’ cardiorespiratory system in laboratory conditions during an 80 hour working shift under controlled microclimate. Participants in the experiment were questioned in order to assess suits’ ergonomics. Heat exchange dynamics and amount of changes in thermal physiological parameters caused by wearing a protective suit determined heat contents of volunteers’ bodies that conformed to optimal standard values. Data on psychophysiological and mental state taken in research dynamics didn’t have any statistically significant changes. Gas exchange indicators naturally grew during the “load” phase; however, there were no significant changes detected in any phase in the research. Hygienic assessment of the thermal state, functional state of the cardiovascular and respiratory systems, and psychophysio-logical indicators confirmed that wearing a protective suit was quite safe and didn’t involve any health risks for volunteers.

The article presents the results of a study on the functionalisation of synthetic textile materials with spherical activated carbon using an adhesive to create personal protective equipment based on Russian components. These materials are of particular relevance in the production of sorption and filtering personal protective equipment, which must have, along with high protective characteristics, high performance properties, vapour and air permeability. In the course of the work, the influence of the plasma of a capacitive high-frequency and low-pressure discharge on the modification of the base material was investigated. It has been proven that plasma treatment of polyester nonwoven material accelerates sorption processes, ensures uni-form coverage of fibres with a binder, which allows maintaining the material's air permeability. The results of studies of the material for the time of protective action on ammonia demonstrated the prospects for the development of Russian sorption-filtering textile material on a non-woven polyester base with a monolayer of granular activated carbon fixed on a polymer binder.
