The study of the link between the work intensity and indicators of the cardiovascular system is presented. The assessment of sensory loads and daily monitoring of the arterial pressure of civil aviation pilots during a training flight at the training complex were carried out. The increase in the number of sensory signals at different stages of flight leads to an increase in arterial pressure.

Introduction. The analysis of working conditions of pilots of civil aviation aircraft has been carried out according to the data of sanitary and hygienic characteristics (SHC). The non-compliances with hygiene standards for several factors have been established at the same time in all SHC. Materials and methods. The 220 SHC of pilots, who had been examined in the clinic of FSBSI RIOH due to suspicion of occupation disease from 2015 to 2019, conducting flights by plane (49%) and helicopter (51%) were analyzed. The methods of account of acoustic load, hygiene assessment and classification of working conditions, peer review methods, and statistical treatment methods have been used. Results. The working conditions, according to the criteria of the Guide R 2.2.2006-05, are assigned to the following classes: 3.2 - in 26%; 3.3 - in 41%; 3.4 - in 33%. Exceeding the permissible equivalent noise levels was recorded at 92% of workplaces. According to SHC, the exceedances were from 1.2 dB to 34.5 dB (class 3.1-3.4). In assessing the work intensity in 83% of cases from 5 to 11 indicators of class 3.2 were recorded. It has determined class 3.3 of work intensity. The levels of general vibration exceeded hygiene standards in 48% of cases (class 3.1- 3.2), local vibration - in 8% (class 3.1-3.2), microclimate parameters - in 67% (class 3.1-3.2), labour severity - in 22% (class 3.1-3.3), less often there were discrepancies in light (6%) and chemical factor (2%). Conclusion. According to a combination of factors, the overall assessment of working conditions of the pilots of civil aviation aircraft in 74% of cases is assigned to classes 3.3-3.4. However, the disadvantages and errors in filling out the SHC can underestimate the degree of harmfulness of the work. To improve the procedure of establishing the connection between the disease, and the profession it is necessary to amend the legislative framework to obtain objective information about the levels of factors affecting pilots, develop a separate form of SHC of working conditions of pilots, detailed instructions about the rules of filling out SHC.

With the help of daily monitoring of blood pressure we assessed the state of the cardiovascular system of foot-platemen of the Prydniprovsk railway Pjatykhatky Depot. Foot-platemen having the I stage of arterial hypertension demonstrated the 11–17% increase of arterial pressure during daily work. It is related to inefficient adaptation to the physical and psychoemotional overloads. With aggravation of the disease the change of arterial pressure during the work, especially night work, ismisaligned and characterised by considerable structural abnormalities of the left ventricle myocardium.

Introduction. An essential feature of the professional activity of pilots of civil aviation aircraft is the high intensity of work due to pronounced emotional, intellectual, and sensory loads, unique work modes. The study aims to assess the intensity of work and the prevalence of factors affecting fatigue among civil aviation pilots according to an anonymous online questionnaire. Materials and methods. Experts surveyed 667 members of the flight crews in remote anonymous online questioning. We developed the questionnaires under the criteria for assessing the intensity of work, assessing the risk factors for fatigue development according to the ICAO recommendations, and analyzing the pilot's activity algorithm. The researchers used descriptive statistical methods to analyze the survey data. Results. The working conditions of pilots according to 7 indicators of tension correspond to class 3.2: a high level of intellectual loads (72-100% of pilots), a large number of overlapping time zones (18%), the maximum duration of concentrated observation (70.7%), a high density of signals and messages (29.9%), a significant number of objects of simultaneous observation (18.9%), a high degree of risk to one's own life and responsibility for the safety of others (98%), as well as a rough working day (79%). According to the totality of indicators, the general class of labor intensity corresponds to the highest degree (class 3.3). The factors affecting the fatigue of pilots include rare rest between flights (44.6% of respondents), intermittent sleep (59.9%), not always a full sleep before the night flight shift (85.9%). According to the survey results, the share of pilots who have spontaneous sleep during the flight is 74.3%, and frequently delayed reaction to usual, non - standard, or extreme stimuli and signals is 12.3%. Conclusions. The obtained data of the questionnaire survey confirm the results of psychophysiological studies that have shown that the level of the labor intensity of pilots is "super-intense or extreme." Therefore, considering the prevalence of factors affecting fatigue among the crew members, and based on the understanding of the fundamental problems noted by the pilots, it is necessary to develop measures and management solutions to minimize the risk factors for fatigue development.

Stimulation Of

Electrical stimulation of a canine vagosympathetic complex or a cardiopulmonary nerve can elicit a variety of negative chronotropic and inotropic cardiac responses, with or without alterations in systemic arterial pressure. In the period immediately following cessation of such a stimulation "rebound" tachycardia, increased inotropism above control values in one or more regions of the heart, and (or) elevation in systemic arterial pressure can occur. These "rebound" phenomena are abolished by propranolol or ipsilateral chronic sympathectomy. It is proposed that "vagal" poststimulation "rebound" of the canine cardiovascular system is primarily the result of activation of sympathetic neural elements present in the vagosympathetic complexes or cardiopulmonary nerves.

В статье рассматривается этапность развития одного из шести компонентов иноязычной компетентности — словарного запасa. Особое внимание уделяется понятийному содержанию этого термина, его структуре в методическом, общелингвистическом и авиационном контекстах, акцентируется внимание на специфике развития лексических навыков в авиационном вузе. Обосновывается важность словарного запаса в общей структуре иноязычной компетентности будущего пилота. Понятийный анализ термина «словарный запас» позволяет дать ему авторскую формулировку, в полном объеме раскрывающую его специфику применительно к обучающимся авиационного вуза с учетом регистра речи. Этапами в данном исследовании выступают учебные модули, предусмотренные учебным планом и основной образовательной программой вуза. В процессе наблюдения за речевой деятельностью курсантов выявляется частотность ошибок, допускаемых при употреблении слов. В ходе проведения анализа авторы руководствуются требованиями Международной организации гражданской авиации, предъявляемыми к языковой компетенции авиационных специалистов, и определяют объем словаря, необходимого для осуществления эффективной коммуникации. The article deals with the stage-by-stage approach to the development of one of the six components of foreign language competence — vocabulary. Special attention is given to the conceptual content of the term vocabulary, its structural components, related to teaching technique, general linguistic and aviation contexts. The authors emphasize the peculiarities of the development of lexical skills at Aviation Institutes. The paper emphasizes the importance of vocabulary in the general structure of foreign language competence. A conceptual analysis of the term “vocabulary” suggests usage of vocabulary with a focus on its specific features at Civil Aviation Institutes, with regard to the register of speech. In this study, the stages are considered to be the learning modules specified by the syllabus and the principal educational program of the Institute. The process of monitoring the cadets' foreign language performance has revealed the frequency of mistakes made in the use of words. In the course of the analysis, the authors follow the requirements of the ICAO (International Civil Aviation Organization) for the language competence of aviation specialists and estimate the vocabulary size for effective communication.
