Occurrence of occupational disease in the South Bohemian region
KUČEROVÁ, Eva
When evaluating effects of work on human health it should be remembered that health is a result of mutual effects of several factors. The factors include the general environment and the working environment, genetic factors and lifestyle. Further, the evaluation of a worker´s health condition should take into account his/her exposure outside work. I have selected the topic of the thesis: ``Occurrence of occupational disease in the South Bohemian region `` because I find occupational hygiene the most interesting sphere in the hygienic sector. The objective of my work was to map occupational diseases in the South Bohemian region and to determine the situation in occupational diseases in a selected period. The selected period was 2004 {--} 2008. At the beginning of the thesis I set two hypotheses. The first hypothesis stated that the number of occupational diseases in the South Bohemian region in 2004-2008 was not statistically significantly different from the national average. To test the hypothesis I used a statistical survey using the Student t-test. The second hypothesis stated that occupational diseases occurred most frequently in persons working in the sector of health and social care and veterinary activities. In the case of the first hypothesis the results have confirmed that the number of occupational diseases in the South Bohemian region does not exceed the national average, except in 2007, when the number of occupational diseases was different from the national average. Also the second hypothesis was confirmed (except in 2008, when the number of occupational diseases in the sector of metal structure manufacturing and metal-working products was slightly higher than in the sector of health and social care and veterinary activities). This thesis seeks to evaluate the trends of occurrence of occupational diseases, which may be used for development of preventive measures in this field, particularly by employers and occupational medicine professionals.

Assessment of the health hazard pertaining to the selected working conditions concerning manufacture of concrete-based products in the selected manufacturing plant
BRULÍK, Petr
In the working environment relating to the manufacture of concrete-based products there are many risk factors that may have a negative impact of the health condition of the employees. Among the most significant factors affecting the organism of every employee involved in the manufacture of concrete-based products there are in particular noise, physical strain, operating position and vibrations. Among these most significant factors, I have concentrated on noise and vibrations in the selected manufacturing plant as the plant was equipped with a new automatic machine where everything is controlled and performed by means of controls and where physical strain or unacceptable working conditions are nearly missing. In the theoretical part of the thesis, I focused on the assessment of health hazard and the relating aspects concerning noise and vibrations and the effect thereof on human organism. The goal of the thesis was to formulate a hypothesis concerning the area of assessment of health hazards pertaining to the selected factors present in the working environment closely related to the working conditions attributable to the manufacture of concrete-based products in the selected manufacturing plant. Three hypotheses were formulated, the assessment of health hazards pertaining to factors relating to the working conditions concerned was performed, the works were classified into the categories prescribed by the applicable legal regulations and the precautionary measures aiming at the protection of the employees at work were proposed. The thesis was based on the application of a qualitative survey, using in particular the secondary data analysis methodology compiling study of specialist information sources, the applicable laws and by-laws and relevant reports. The values obtained by measurement were processed and subsequently compared with the sanitary limits prescribed by the applicable legal regulations. The hypotheses have been proven due to this methodology and the goals have been achieved. It has been confirmed that values exceeding limits imposed by the applicable legal regulations are present in the manufacturing plant concerned. Noise seems to be a more significant risk factor than vibrations here and the proposed precautionary measures should eliminate damage to health of the employees due to the effect of the working conditions concerned. In practice, this thesis can serve for the purpose of improvement of awareness in the area of health hazard arising from working conditions pertaining to manufacture of concrete-based products and improvement of efficiency of the precautionary measures taken.
