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.

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.

Introduction. Discrepancies in the regulatory documents regulating the compilation of sanitary and hygienic characteristics (SGC) of pilots' working conditions, the lack of a complex of laboratory and instrumental studies conducted at the workplace and, as a result, incomplete and unreliable compilation of SGC, lead to difficulties in establishing the connection between the disease and the pilot's profession. The aim of study is to conduct a critical analysis of the quality of the preparation of the CGS, followed by identifying the main violations of the requirements of regulatory documents in the design of the CGS. Materials and methods. A retrospective analysis of the quality of registration of the SGC of pilots with an established diagnosis of occupational disease was performed. Results. Contradictions in the current legal acts are established and discrepancies in methods for assessing the normalized indicators of working conditions of pilots are revealed. The data obtained indicate that the main requirements for filling out the SGC, justified by the specifics of the working conditions of pilots, are not taken into account when they are issued; when evaluating the measurement results, non-current regulatory documents are used, or documents that do not regulate the working conditions of civil aviation pilots. Conclusions. To improve the quality of registration of the SGC, it is necessary to update the current regulations and develop guidelines with the establishment of the form of the SGC for working conditions of civil aviation flight personnel in case of suspected occupational disease.

Calcareous tufa from five sites in southern Poland, representing several most typical conditions of tufa sedimentation, were chosen for 14C, 13C, and 18O measurements. These tufas were deposited in a high-energy turbulent stream (the Racławka site), in streams with moderate but variable flow (Rzerzuśnia and Trzebienice), and in semilimnic conditions (Sieradowice site). Sediments of the Gliczarów site represent spring travertines. In all but the latter site, direct comparison of 14C dates of carbonate and organic fractions was possible, leading to an estimate of initial apparent age of carbonate sediments. Clear correlation was found between the value of initial apparent age of tufas and the hydrodynamic conditions of sedimentation. Corresponding values range from ca 3900 yr (Racławka) to 910 yr for semilimnic sediments (Sieradowice). Intermediate, almost identical values, equal to 2460 ± 200 yr and 2100 ± 160 yr, were obtained for tufas from Rzerzuśnia and Trzebienice, respectively. Detailed sedimentologic classification of tufaceous deposits is presented and some primary and secondary factors affecting the accuracy of radiocarbon dates of various types of tufas are also discussed.

The article is aimed at developing scientific-methodological recommendations for the integrated multi-criteria assessment of intellectual capital. Achieving this goal requires solving the following tasks: analysis of the theoretical principles of intellectual capital; analysis of intellectual capital components; analysis of methods for assessment of intellectual capital; development of a multi-criteria model of integrated assessment of intellectual capital on the basis of program-target approach and utility theory. In line with the conception of management by objectives, as well as in accordance with both the systemic and the program-target approaches, the objectives of enterprise are formulated taking into account the growth, renewal and efficient use of intellectual capital. Based on the analysis of available publications, a classification of factors affecting intellectual capital is compiled. Using the structure of intellectual capital and graph theory, the «tree of purposes» of intellectual capital is built, which represents an unoriented, bound graph, the verticals (nodes) of which are purposes, and the ribs (arcs) are the links between them. A system of criteria – indicators that affect the achievement of the objectives is formulated. As a criterion for optimality of achieving the objective, it is proposed to use the multi-criteria utility function. It is noted that in order to assess intellectual capital, it is advisable to use the additive utility function, which makes it possible to compute the integral indicator of intellectual capital. This, in turn, allows to analyze the growth, renewal and efficiency of the intellectual capital of enterprise over a number of years, as well as compare enterprises with each other.
