An expert evaluation of identifiability of cardiovascular diseases was carried out together with a clinical and functional examination of certain groups of miners of basic underground occupations at different ages and lengths of service, that showed a high incidence of cardiovascular diseases along with a low informative value of methodical approaches, indices and criteria used for their diagnosis in conducting preliminary and periodic health check-ups. To improve the quality of diagnosis of diseases of the circulatory system it is necessary that standardized methods of investigation should be employed together with consistent indices of high informative value as well as a purposive training of physicians.
Presented are the results of antioxidant status of inhabitants of Yakutia. The intensity of lipid peroxydation depends on professional factors: influence of the quartz dust and smoking. Miners and smokers have high concentration of malonil dialdegide in blood. The SOD and catalase levels did not statistically depend on sex and nationality, but increased in miners and smokers. Insufficiency of vitamins C, A and E combined with immunoglobulins deviations. It should be noticed that country-people have more deviations in vitamin and immune status than towns-people.
This study was carried out to assess Future Workshop (FW) regarding its usefulness as a participatory ergonomics method, using a descriptive evaluation design analysed by phenomenographical approach. The study was conducted among professional cleaners, health care personnel and miners, with a sample of 105 participating subjects in 8 different FWs. Multiple methods, giving a combination of both qualitative and quantitative data, were used for data collection. Good involvement of participants was observed during workshops. Evaluations immediately after FWs and 3 months later showed a strong relationship with high correlation, indicating that the perception of FW participants was very positive. Interviews revealed conformity between developed problem identification and proposed changes. Participants' own perceptions of FW's influence on creativity depict their belief of developed ideas and solutions in order to identify and solve workplace problems. FW is considered to be a useful ergonomics tool, and its qualities are related to structure and practical performance.
Characteristics, frequency and distribution of vertebrogenic diseases involving cervico-brachial region were studied in more than 1,000 miners from asian North and East exposed to vibration. The data were compared with the results of examination of drivers. The investigation revealed a high level of vertebrogenic cervical pain and cervico-brachial pain in miners with a long length of service, especially in those suffering from vibration disease and frequent osteochondrosis manifestation in younger age, especially in subjects working beyond the Polar Circle. Occupational hazards are proved to play a leading role in the early development of vertebrogenic diseases, and vibration disease predisposes to such pathology. The results make possible to consider the vertebrogenic cervical pain and cervico-brachial pain as occupational diseases in young-aged workers with long length of service or evaluate such diseases as complications of vibration disease in individuals facing this occupational pathology.
Miners working in deep coal mines, engaged in hard physical work under most harsh mine conditions demonstrate a striking imbalance between pro- and antiinflammatory cytokines and a rise in the blood levels of electrolytes K+ and Na+ as well. The analysis performed revealed a direct correlation between the level of blood concentration of IL-6 and that of K+, Na+.
The authors studied psychophysiologic state of operators in coal industry and metallurgy, who were considered healthy and suitable for the work. Only 60% of the examined metallurgy operators and 21% of those engaged into coal industry appeared to meet the occupational medical requirements. By the end of the working shift 50% of the operators showed decrease of attention and 28-36%--depression of visual and hearing memory. Occupational overload induced compromised psychophysiologic parameters in 70% of the examinees. Heating combined with other hazards resulted in marked asymmetry of heating sensation, changed body heating, lower hearing sensation, worse attention, memory, decision making, emotional state.
