Sensory Polyneuropathy

Introduction. Autonomous sensory polyneuropathy of upper extremities is one of the most common occupational diseases of the peripheral nervous system. Materia and methods. Findings of the health state study in two major worker jobs in which occupational polyneuropathies of upper extremities are prevalent, namely: house-painters and plasterers, as well as mining job workers (underground miners, shaft miners, breakage face miners), are reported. The main harmful factor in both professional groups is the heaviness of the working process. Results. Physical overloads are a reason of the occupational pathology’s complex of “working hand”. At the same time, no systemic autoimmune or endocrine diseases with similar polyneuropathy were detected. Other harmful factors in the working process such as occupational dust, intensive noise can cause another occupational pathology (in respiratory or hearing organs). Discussion. In spite of obviously different working conditions, we detected the same professional diseases in both professional groups - “the working hand pathological complex”. Our findings indicated the importance of the regular periodic check-ups. Doctors should search actively the early signs of coexisting with the occupational polyneuropathy illnesses. The results of health state’s research should be taken into account in the patient’s treatment planning.

Autonomous sensory polyneuropathy of upper extremities is one of the most common occupational diseases of peripheral nervous system. Findings of the study of working conditions in two major worker jobs in which occupational polyneuropathies of upper extremities are prevalent, namely: house-painters and plasterers, as well as mining job workers (underground miners, shaft miners, breakage face miners) are reported. Hygienic investigations envisaged detailed studies of working conditions in workers with diagnosed occupational peripheral nervous system disease. The intensity and hardness of working process, illumination level, spectral noise characteristics, noise, vibration, temperature, humidity, and air velocity levels, as well as adverse chemical concentrations in workplace air were assessed. House-painters as well as miners were found to work with pronounced physical overloads, working conditions being classified as 3.2-3.3 (2-3 degree harmful) according to indices of working process hardness. In spite of new technologies being introduced into the working process, manual labor part in these jobs still remains to be the great. Comparison of findings revealed certain differences in some characteristics of working process hardness. Working process hardness shown by dynamic and static physical load on upper extremities was found to be the most significant harmful occupational factor resulting in polyneuropathy in house-painters and plasterers. Development of polyneuropathy in miners was caused by a combination of adverse occupational factors: working process hardness, local vibration, cold microclimate. Our findings indicated the importance of the study of health state in painters and miners. Working conditions must be taken into account in the process of development of preventive and remedial measures for occupational polyneuropathy treatment.

Introduction. Professional groups of railway workers engaged in the repair of wagons are directly responsible for the safety of railway traffic. The analysis of literature testifies to insufficient attention of researchers to the hygienic problems associated with labor activity of workers of wagon-repair production.The aim of the study is to assess the occupational risk to the health of wagon repair workers, due to the impact on them of factors of the working environment and the labor process.Materials and methods. The study used comprehensive hygienic studies using the methodology of occupational risk to worker’s health.Results. The leading factors of the working environment (class of working conditions 3.2–3.4), which are exposed to workers depending on the specifics of the work performed. Identified professional groups with medium (significant) high (unbearable) and very high (intolerable) category of a priori occupational risk: in wagon meintenance workshop — 17 groups (94% of jobs), in a wagon assembly workshop — 11 groups (80% jobs), in wagon wheel workshop — 3 group (100% jobs). At the same time, according to the request for medical care, employees were diagnosed with isolated cases of occupational diseases.The levels of morbidity with temporary disability of employees of the main workshops are statistically significant (p<0.05) higher than those of the control group in 1.4–1.9 times. The influence of the complex of chemical factors of low and medium intensity on the levels of morbidity of respiratory diseases in the group of workers of the wagon wheel workshop, which were 1.7–2.0 times higher than in the control group, is confirmed by the average degree of causation of the production condition of this pathology (RR=1.7; EF=42.0%).The combined effect of vibration and severity of the labor process forms a high level of temporary disability of employees of the main workshops in connection with diseases of the musculoskeletal system, which was 2.7–4.4 times higher than in the control group, and also determines the prevalence of this pathology in the structure of diseases detected on medical examinations (23.2%). Diseases of the musculoskeletal system are caused by the production of employees of the wagon meintenance workshop (RR=3,9; EF=74,9%), as the most unfavorable in terms of hygiene on these factors.The stressful influence of the complex of harmful production factors on the health of wagon repair workers is manifested by the high risk of diseases of the cardiovascular system, gastrointestinal tract, neurological disorders, violation of adaptation of the cardiovascular system in 97% of the examined, as well as the predominance of diseases of the digestive system and circulatory system detected on periodic medical examinations.Conclusions. Harmful working conditions (class 3.1–3.4) cause the suspected occupational risk from small (moderate) to very high (intolerable) to 100% of the jobs of wagon repair workers. The results of the study of morbidity and risk of pathology indicate a significant risk of damage to the health of workers.

In the present research, the working conditions of workers employed in the production of medicines in the form of tablets and capsules of a modern enterprise of the pharmaceutical industry have been studied. Based on the results of attestation of workplaces and data of industrial laboratory control of the factors of the production environment for the period from 2016 to 2019, a complex of harmful production factors at workplaces was determined and a comprehensive hygienic assessment of the working conditions of a general purpose machine operator of chemical and pharmaceutical preparations, packaging machine operator, stacker-packer and processor of technological containers and tares. It has been established that the labor activity of the leading professional groups of workers in production is associated with the influence of a predominantly chemical factor due to the presence of harmful chemicals in the air of the working area. According to the data obtained, the air of the working area at the workplace of the operator of a wide profile of chemical and pharmaceutical preparations of the tableting and filling of capsules section is contaminated with harmful chemicals (doxycycline, nystatin, lincomycin, rifampicin, tetracycline, etc.), the concentrations of which exceed the maximum permissible. A hygienic assessment of the parameters of the microclimate, noise and tension of the labor process at the studied workplaces established that there are no deviations from hygienic standards and the working conditions according to these factors are permissible. Thus, the data obtained allow us to conclude that the working conditions of the operator of a wide profile of chemical and pharmaceutical preparations belong to class 3.3, the stacker-packer — 3.1, and the working conditions of the operator of filling and packaging machines and the processor of technological containers and tares are assessed as acceptable.

Path System

The gas path system is an important part of an aero-engine, whose health states can affect the security of the airplane. During the process of aircraft operation, the gas path system will have different working conditions over time, owing to the change of control parameters. However, the different working conditions which change the symmetry of the system will affect parameters of the health state prediction model for the gas path system. The symmetry of the system will also change. Therefore, it is important to consider the influence of variable working conditions when predicting the health states of gas path system. The accuracy of the health state prediction results of the gas path system will be low if the same evaluation standard is used for different working conditions. In addition, the monitoring data of the gas path system’s health state feature quantity is huge while the fault data which can reflect the health states of the gas path system are poor. Thus, it is difficult to establish a health state prediction model only by using the monitoring data of the gas path system. In order to avoid problems, this paper proposes a health state prediction model considering multiple working conditions based on time domain analysis and a belief rule base. First, working condition is divided by using time domain characteristics. Then, a belief rule base (BRB) theory-based health state prediction model is built, which can fuse expert knowledge and fault monitoring data to improve modeling accuracy. The reference value of the feature is given by the fuzzy C-means algorithm in a model. To decrease the uncertainty of expert knowledge, the covariance matrix adaptive evolution strategy (CMA-ES) is used as the optimization algorithm. Finally, a NASA public dataset without labels is used to verify the proposed health state model. The results show that the proposed health prediction model of a gas path system can accurately realize health state prediction under multiple working conditions.

Stage Of Development

Introduction. The modern stage of development of electronics is characterized by the widespread use of integrated circuits (IC). Assessment of working conditions in a promising, developing production of electronic components with hygienic positions is an urgent task.The aim of the study is to conduct a hygienic assessment of working conditions of workers in the main professions in the production of IC.Materials and methods. Hygienic research conducted at three modern enterprises for the production of chips and semiconductor devices, included the study of the conditions and nature of work of workers in the main professions. 215 chemical analyses for the content of harmful substances were carried out in order to assess the air environment and 270 measurements of the levels of physical factors at 18 workplaces.Results. Findings of hygienic assessment of working conditions for employees engaged in manufacture of microcircuits: operators of chemical processing, precision photolithography (PPL), diffusion processes, vacuum deposition, and IMC assemblers are reported. Based on the analysis of the technological process and the list of materials used and time-study data, the studies of workplace air pollution, sound levels, artificial lighting, microclimate parameters (temperature, humidity, air velocity), working process parameters were carried out. The jobs in which work is characterized by toxic chemicals exposure, precision visual operations using optical instruments during 55% of the shift were singled out. Priority occupational health risk factors for workers employed in modern IMC production and main areas of working environment optimization were revealed.Conclusions. Based on the conducted hygienic studies, musculoskeletal system load combined with visual strain were found to be the priority occupational health risk factors for microcircuit production workers. Manual operations taking up a significant part of the working process and introduction of automated IMC technological processes being insufficient, preventive measures should be aimed at organizing a rational working regime that provides reducing of visual strain and musculoskeletal system load.

The Impact

The work presents data analysis of the results of special assessment of working conditions for workers of various branches of economy in the Bashkortostan Republic. Results of special assessment of working conditions (SAWC) and medical examinations were used for the analysis. It is noted, that some professional groups, for example, persons performing their work in the sphere of agriculture, have no exposure to the biological factor. Construction workers were not exposed to industrial vibration, while the noise level for half of the analyzed cases was of class 2.0, although in most cases, industrial noise and vibration have single source. Proportion of facilities that revealed a discrepancy between levels of harmful industrial factors and requirements of sanitary legislation remains high. The greatest share of objects does not correspond to sanitary and epidemiological requirements according to the chemical and physical factor. At the moment, SAWC does not fully reflect the working conditions of employees in different sectors of production. Underestimation of its influence on working conditions of workers is typical for a considerable number of professional groups and individual jobs. Analysis on the basis of SAWC is not sufficient for a hygienic assessment of the impact of production environment factors and labour process on health and requires comprehensive assessment methods.
