The purpose of this study was to investigate the effects of safety culture on the safety awareness and safety behaviors of manufacturing workers, and to suggest ways for manufacturing workers to understand the safety culture and improve safety awareness and safety behavior. In order to verify this, data were collected from 282 research subjects for 1 month from August 1 to 31, 2018, using the manufacturing workers in the Seoul and Gyeonggi area as a population. The results of the study are as follows. First, the safety culture (safety climate, safety procedures) has a positive effect on the safety awareness (recognition of importance, interest and participation inducement) of the manufacturing workers. Second, the safety culture (safety climate, safety procedures) has a positive effect on the safety behavior (safety planning, safety check) of manufacturing workers. Third, safety awareness (recognition of importance, interest and inducement of participation) has a positive influence on the safety behavior (safety planning, safety check) of manufacturing workers. Fourth, the safety awareness (recognition of importance, interest and inducement of participation) appears to have a partial mediating effect in relation to safety culture (safety climate, safety procedure) and safety behavior (safety planning, safety check) of manufacturing workers. The implication of this study is that although the industrial accidents have occurred in the manufacturing industry in recent years, the studies on the workers in the manufacturing industry are insufficient. However, this study is meaningful that it has suggested ways for manufacturing workers to understand the safety culture and improve the safety awareness and safety behavior by analyzing the effects of safety culture on safety awareness and safety behavior of manufacturing workers.

The purpose of this study was to investigate the effects of safety culture on the safety consciousness and safety behaviors of manufacturing workers, and to suggest ways for manufacturing workers to understand the safety culture and improve safety consciousness and safety behavior. To achieve this research objective, out of 176 industrial complexes in Seoul and Gyeonggi Province registered with the Korea Industrial Complex Corporation, workers at 50 industrial complexes, including the Korea Export-Industrial Complex and Seoul's Onsuji, were subject to research. The implementation of this survey distributed 300 questionnaires through the mid-level managers of manufacturers and environment safety and health managers over a period of one month from August 1st to 31st, 2019, finally statisticalizing the data in 282 parts excluding 18 questionnaires deemed to have been unresponsive. First, the safety culture (safety climate, safety procedures) has a positive effect on the safety consciousness (recognition of importance, interest and participation inducement) of the manufacturing workers. Second, the safety culture (safety climate, safety procedures) has a positive effect on the safety behavior (safety planning, safety check) of manufacturing workers. Third, safety consciousness (recognition of importance, interest and inducement of participation) has a positive influence on the safety behavior (safety planning, safety check) of manufacturing workers. Fourth, the safety consciousness (recognition of importance, interest and inducement of participation) appears to have a partial mediating effect in relation to safety culture (safety climate, safety procedure) and safety behavior (safety planning, safety check) of manufacturing workers.

Korea is becoming an aged society as well developed country. Accident rates of elderly workers are increased. When elderly workers injured, elderly workers are more likely to die as a result, and they take longer to recover than young workers. Thus the cost to industry per individual accident gets higher for elderly workers. If information on the occupational accidents of elderly workers could be collected and analyzed for the purpose of preventing occupational accidents, we would be able to get rid of accidents of elderly workers. The accidents of elderly workers in small manufacturing factories were considered in this study. 97 accidents, which occurred in 1995-1998, were investigated. These accidents were analyzed in terms of sex, work period, cause of accident and form of accident. The accidents of elderly workers in small manufacturing factories are numerous and are often serious and worthy of greater attention than they have received. Successful strategies for accident prevention depend on effective analysis.

Purpose: Regular cancer screening for workers can help prevent cancer or allow early treatment, and is thus beneficial in improving health, reducing costs, and increasing companies' productivity. However, there has been little research on cancer screening rates of workers and related factors. The purpose of this study was to identify cancer screening rates and relevant factors among manufacturing workers. Methods: Using a questionnaire, data were collected from 335 workers aged over 40 years recruited from seven manufacturing companies. The collected information included cancer screenings (stomach, colorectal, breast, and cervical), attitude towards cancer screening, and demographic and job characteristics. Results: 72.5% of workers received stomach cancer screening (SCS), and 43% received colorectal cancer screening (CRCS). Among 86 women, 68.6% received breast cancer screening and cervical cancer screening. The attitude towards cancer screening was $29.5{\pm}3.78$. Workers aged over 51, married, and those working in mobile manufacturing were more likely to have undergone SCS. Workers aged over 51, married, those working in mobile manufacturing, those in workplaces with more than 1,001 employees, and those with more positive attitudes toward cancer screening were more likely to have undergone CRCS. Finally, attitude affected cervical cancer screening. Conclusion: Workers in small-sized workplaces had lower cancer screening rates. Thus, follow-up research should assess the health environment of workplaces and develop educational programs on cancer screening that reflect attitudes towards screening.

This study was carried out to assess work ability of manufacturing workers and managerial workers. Subjects were 446 manufacturing workers and 278 managerial workers employed in Gumi industrial complex and the observation period was for 1 month(February to March), 1995. In this study, as a questionnaire for the assessment of work ability, we used the Work Ability Index(WAI) which was developed by Institute of Occupational Health in Finland. Major findings obtained from this study were as follows ; WAI was poor in lower economic condition, shift work, irregular diet group(p<0.05). There were no evident trends of WAS in sex, educational level, obesity index, exercise, smoking, and alcohol drinking. In the groups of sensitive to perception of stress, other industrial classification except textile and electronics, the more than 9 hours work, the evident trends of poor WAS were observed(p<0.01). In the groups of $30\sim39$ years old, $40\sim49$ years old, unmarried, high school, shift work, standard body weight, and regular .diet, WAI between manufacturing workers and managerial workers was significantly different(p<0.01) and WAI of managerial worker was worse than that of manufacturing worker.

Objectives: Polyurethanes are usually formed by the reactions of liquid diisocyanate components with liquid polyol resin components. Although polyurethanes have advantageous properties, such as their versatility, the manufacturing process generates diisocyanates, which can cause asthma and respiratory irritation in exposed workers. This study compared the differences in diisocyante concentrations between two different (molded foam and slabstock foam) polyurethane foam manufacturing methods. Materials and Methods: Active samples and direct reading samples of diisocyanates (MDI, TDI) were collected in five polyurethane foam manufacturing companies. Results: Workers' exposure concentrations of diisocyanate (GM: 4.078 ppb, range: 1.190~23.770 ppb) in a slabstock foam manufacturing company were much higher than those (GM: 0.011 ppb, range: 0.001~0.055 ppb) in molded foam manufacturing companies. The results of the direct reading samples of diisocyanate indicated that the rapid reaction zone of the slabstock foam processes emitted large amounts of diisocyanates. Conclusions: The exposure levels of diisocyanates for all molded foam workers were much lower than the occupational exposure standard (5 ppb); however, exposure levels for many slabstock foam workers exceeded the standard.

Objectives: Skin exposure to diisocyanates may be an important risk factor for respiratory sensitization to leading asthma. However little is known about the extent of worker's diisocyanates skin exposure and the effectiveness of personal protective equipments in polyurethane foam manufacturing companies. This study provides data on diisocyanates skin exposure, surface diisiocyantes contamination of foams and the effectiveness of personal protective gloves in five polyurethane foam manufacturing companies. Materials and methods Colorimetric SWYPE pads are used for the determination of diisocyanates on surfaces of workers skin and polyurethanes foams. Results: The forearms, necks and faces of workers in polyurethane foam manufacturing companies were found to be contaminated with diisocyanates. Heavy contamination with uncured diisocyanates at large block foams surfaces were found. Personal gloves of workers for skin protection showed significant penetrations by diisocyanates. Conclusions: We found that all workers in polyurethane foam manufacturing companies could be exposed to diisocyanates by skin exposure. Also further researches which would better quantify skin exposure are needed.

Objectives. This study was carried out to analyze the hearingthreshold levels and relating factors of 1,048 workers with noiseinduced hearing loss$(D_1)$. Methods. We analyzed the hearing-threshold levels and relating factors of 1,048 workers with noise-induced hearing loss$(D_1)$ examined by the summary reports of specific health examination results of industries and personal reports of specific health examination results reported by 58 specific health examination institutes and 8 secondary pneumoconiosis examination institutes in 1996. Results. Among 1,048 workers at 510 workplaces, male workers were 1,009 (96.3%) and female workers were 39 (3.7%). The mean ages of workers initially exposed to noise and at present were 28.7 and 47.2, respectively. The duration of total exposure was 16.5 years. Average hearing-threshold levels analyzed by three-divided classification of the study subjects were 43.7dB(Lt) and 42.6dB(Rt). Those analyzed by six-divided classification were 50.5dB(Lt) and 48.6d8(Rt). Among workers with noise-induced shearing loss$(D_1)$, 16.3% was unilateral hearing loss and 84.6% was classified to compensation case. 8.8%(Rt) and 10.2%(Lt) of them were suspected to be conductive hearing loss by differences of air-bone hearing-threshold levels. Hearing-threshold levels of workers in manufacturing industry were significantly increased during the short exposure compared with the levels in mining industry. Among manufacturing industries, hearing-threshold levels of workers in trailer and other transportation equipment manufacturing industry were significantly increased. Age and duration of total noise exposure were not significantly related to the average hearing-threshold levels analyzed by three-divided classification. Hearing-threshold levels of female workers were significantly increased during the short exposure compared with those of male workers. Hearing-threshold levels of workers at the high risk group, ages of 20s, 30s and total exposure duration of less than 10 years, were not significantly increased compared with those of the other groups. However, they were exposed at young ages. The 3 leading industries of workers at high risk group were trailer and other transportation equipment manufacturing, automobile manufacturing and assemble-metal manufacturing industries. Conclusions. This study was the first nationwide analysis of the hearing-threshold levels and relating factors of workers with noise. induced hearing loss$(D_1)$. We found the differences of the real number by the statistics of the department of labour and the expected number of worker' s compensations for occupationally-induced hearing loss estimated by this study. According to the results of this study, we should carefully examine the methods to narrow this difference.

Objective: This study aims to understand the occupational injury characteristics of the workers in the motor vehicle parts (automobile parts) manufacturing industry and to present basic guidelines on accident prevention through accident analysis. Background: There occur many occupational injuries in the motor vehicle parts manufacturing industry. But there were few researches for the occupational injuries of the workers in the motor vehicle parts manufacturing industry. Method: This study analyzed the data of occupational injuries of 1,609 workers in the motor vehicle parts manufacturing industry in 2015. The accident characteristics were analyzed by dividing them into worker related factors and accident related factors. Results: Among the occupational injuries of the workers in the motor vehicle parts manufacturing industry, 80.6% of the victims were males, 64.0% were older than 40. 57.8% of the victims were employed by the companies with less than 50 workers. In addition, there was a difference in accident characteristics according to age, work experience, employment type, events or exposures, accident time of the day, agents, natures of injuries and illnesses, injured organs and injured body part. Conclusion: It is important to prevent equipment/machinery accidents. For this purpose, more efforts should be made to establish safety measures faithful to the basics of safety devices and safety work procedures. It is also suggested that prevention of disasters should be intensively carried out for workplaces with less than 50 employees and middle-aged and elderly people. Application: The result can be used to present guidelines for preventative measures for the workers in the motor vehicle parts manufacturing industry including safety education/training.
