A Study on the knowledge and Attitude of Workers Concerning Occupational Health / 대한산업의학회지

To acquire more useful data for the improvement of industrial health servicies, the knowledge-attitude study was carried out by questionnaire on 264 workers in Incheon area from November, 1989 to March, 1990. The results of this study were as follows; 1. Almost half of workers responded that their health status in poor. 2. The Knowledge of respondents on occupational health showed considerable difference depending upon duration of work in their company. Genverally, the respondents with long duration of work tend to be higher in knowldedge score than those with short duration of work. 3. Most of the workers (82.6%) thought that creating better working environment and improvement of working condition would be most efficient way for protecting the workers' health. 4. Degree of labor union activity, duration of work, participation for labor union were revealed as major determinants of attitude for industrial health. 5. Most of workers (91.1%) responded that they would like to participate in health education program if available, and monthly education would be adequate for them. The contents of program which the workers preferred were early detection and treatment of occupational disease.

A Study on the Industrial Accident of Steel Workers / 대한산업의학회지

To investigate the relationship between physical health of workers and industrial accidents, a case-control study was carried out using matched samples of 87 injured steel industry workers and 87 non-injured steel industry workers. One group of people who experienced industrial accidents more than two times were case, and the other group of people who matched the type of work and duration of employment were control. We surveyed questionnaire between July 20, 1988 and July 22, 1988. The results were as follows: 1. The average age of injured workers was 39 years, and non-injured workers was 38 years. Duration of employment of injured workers was 8.4 years and non-injured workers was 8 years. 2. Visual acuity under 1.0 were 24.4 percent in injured workers and 19.5 percent in non-injured workers. Hearing threshold over 40 dB were 77.1 percent in injured workers and 60.9 percent in non-injured workers. 3. As for the Fugamachi classification method, 22.9 percent of injured workers and 20.8 percent of non-injured workers were group III(suspected neurotics). 4. As for the item of CMI(Cornell Medical Index), injured workers were higher rates than non-injured workers in the item of C(cardiovascular system), M(inadequency), O(anxiety), P(sensitivity), Q(anger), and R(tension). 5. Especially, injured workers who had more than three times were higher in the item of C(cardiovascular system), M(inadequency), N(depression), P(sensitivity), Q(anger), R(tension) than non-injured workers.

Change of Skin Temperature of Workers Using Vibrating Tools in Anthracite Mines / 예방의학회지

By implementing epoch-making policies for industrial promotion, the national economy has made a remarkable development. As a result of such economic growth, industrial accidents and occupational diseases have become a serious problem in Korean society. In the presidential order for the execution of the Korean Labor Standard Law, neuritis and other diseases stemming from health impairments due to vibrations in industrial processes are designated to be dealt with as vibration diseases. In the case of vibration disease, industrial accident compensation is not effectively paid. In order to investigate the vibration hazards of rock-drill operation, the authors studied the subjective symptoms and performed physical function tests on a total of 79 persons (vibration exposed group) who used rock-drills, and 39 persons (control group) who did not use rock-drills at anthracite mines. The results of the physical function test were as follows : 1. The right hand was more affected by white finger than the left hand. 2. Independent variables such as duration of rock-drill operation, age, drinking and smoking were identified as statistically significant factors for the occurrence of white finger. 3. In the pain sense threshold, the group with Raynaud's phenomenon showed a statistically higher level than that of the control group. 4. The skin temperature of the group with Raynaud's phenomenon was lower than that of the control group. The recovery time of skin temperature after cooling was delayed compared with the value of the control group.
