The purpose of this study is to investigate attitude factor related to hearing conservation and to find attitude affecting the preventive behavior for hearing conservation. The research method used in this study was self-administered questionnaire samples of the study were composed of 353 workers exposed noise selected randomly in 10 ship-building manufacturing companies. Authors extracted following 9 factors related hearing conservation from 26 attitude propositions prepared from previous study results and health belief model; (l) general perceived susceptibility, (2) relative perceived susceptibility compared with colleagues, (3) concern to the personal protective devices, (4) perceived severity and concern to the hearing capacity, (5) concern to the hearing and noise assessment, (6) concern to the control noise and hearing conservation, (7) group pressure and reason of wearing protective devices, (8) apathy of hearing loss from noise, (9) knowledge about hearing conservation Attitude factors affecting the preventive health behavior were general perceived susceptibility, concern to the noise control and hearing conservation, and concern to the personal protective devices in the case of wearing personal protective devices. But in the case of avoiding noise exposure as preventive health behavior, perceived severity and concern to the hearing capacity was a significant attitude factor with knowledge about hearing conservation.

This study was planned in order to investigate coal miners' recognition and attitude toward pneumoconiosis, and its relationship with related behavior for prevention of pneumoconiosis. Study object was coal miners in Kangneung area, sampled by multistage random proportional sampling, Sample size was 13% of total coal miners in Kangneung area. The results were divided into three parts: (1) descriptive results presented percent distribution, (2) reclassification of knowledge, experiences, and attitude by factor analysis, (3) prediction of health behavior for prevention of pneumoconiosis by discriminant analysis. Knowledge, experiences, and attitude toward pneumoconiosis were classified into nine factors. Knowledge about pneumoconiosis were broken down to two factors and attitude to four factors, and valence, perceived severity were classified into each one factor. According to demographic, socioeconomic characteristics, and factors of knowledge, experiences, attitude about pneumoconiosis, about 62% of behavior of wearing respiratory protector was correctly discriminated. And by the same methods, about 81% of behavior of hospital visit at respiratory symptoms; cough, sputum, chest pain etc. was discriminated correctly.

The purpose of this study is to investigate the present state of worker's recognition and attitude about hazard materials and occupational disease in his workplace. In general worker's view of hazard materials and occupational disease that sis recognition and attitude is related to worker's health behavior for preventing occupational disease and improving his health status. The study subject is composed of workers in the asbestos related industry for example brake lining manufacturing industry, asbestos fiber manufacturing industry, and asbestos slate manufacturing industry. The result of the study are follows; 1. The most of workers in the asbestos related industry have taken health education and safety education, and the more than half of workers recognized the usefulness of preventive device, and ventilatory device in workplace. 2. About 70% of workers have always taken the preventive device. 3. About 80% of workers have recognized occupational disease in the asbestos related industry, and about 64% of workers have recognized that his workplace have harmful effect on his health. 4. Recognition about the usefulness of ventilatory device in work place has not related with any variables. But recognition about the usefulness of repiratory protector has related with recognition of hazard materials in his workplace, for example asbestos. 5. Attitude about severity and susceptability of occupational disease in the asbestos related industry have related with knowledge about hazard materials and occupational disease.

The purpose of this study is to analyze occupational history of coal miners with pnemoconiosis. In this study, occupational chracteristics of 49 coal miners with pneumoconiosis were compared with those of 45 coal miners without pneumoconiosis but in similar age category (43-52 years of age) based on interview survey. Various indices on occupational characteristics were developed for the following areas: duration of employment, perception of working condition, working density, dust concentration, temperature, humidity, and experience of respirator wearings. Perception of working condition were measured in 5 points scales but experiences of respirator wearing was measured in 3 points scale. Each index was multiplied by duration of employment. From the analysis, only the experience of respirator wearing showed statistically significant difference between the two groups. Therefore, respirator wearing seemed to be effective in reducing occurrence of pneumoconiosis.

OBJECTIVES: In this study we performed an analysis of the stress associated with the working conditions of 6,764 workers based on 'A survey of healthy condition of workers on 1999'by the Korean Occupational Safety and Health Agency. The Purpose of this study was to provide basic data for health education and management for industrial workers'health promotion. METHODS: Collected data were analyzed using the t-test, ANOVA and multiple regression analysis, using the SPSS 10.0 program. RESULTS: When the degrees of stress were analyzed according to demographic characteristics, females were found to have higher levels of stress than males (p<0.001). Furthermore, as age was lowered and as the work space became larger, the degrees of a stress were also found to be higher (p<0.001 and p<0.01, respectively). When the degrees of stress were analyzed according to working conditions, longer working hours (p<0.001) and reduced break times (p<0.05), gave rise to higher degrees of stress. Also, as the work space was reduced in size and as the work intensity was augmented, the degrees of a stress were made higher (p<0.01). In terms of physical working conditions, humidity and a lack of sense of security resulted in higher degrees of stress (p<0.01). When the workers sense that their environment is noisy or dusty has poor lighting or ventilation or that the rest room and cafeteria facilities are inadequate, the degrees of stress are found to be higher. As regards the social environment, when the workers sensed that the degree of job demand or job control was higher or that the degree of social support was lower, the degrees of stress were increased (p<0.001). Among those factors which influenced physical stress in the stepwise multiple regression analysis, the primary factor was found to be the safety of the working place (5.1 %). Other factors which influenced physical stress were degree of job demand, age, work intensity, humidity, sexual discrimination, length of working hours, size of work space and the existence or not of a regular break time in this order. Total R2 due to these factors was 12%. Among those factors which influenced mental stress in the stepwise multiple regression analysis, the primary factor was the degree of job demand (4.8 %). Other factors which influenced mental stress were humidity, age, sexual discrimination, the degree of a job control, safety of the working place, degree of social support, a working site, size of the work space, quality of lighting, the existence or not of a regular break time and length of working hours in this order. Total R2 due to these factors was 13.1 %. CONCLUSIONS: The above results shows that working conditions are strongly related to stress. Furthermore, when both physical and social working conditions are continuously managed and improved, workers may not only reduce their levels of stress but also maximize their working efficiency.
