The purpose of this study was to examine the actual dental hygiene status of workers in cement industry in an effort to serve as a basis for enhancing their dental hygiene. The subjects in this study were 420 laborers from the cities of Curi, Donghae and Samcheok who handled cement. As a result of conducting a survey, the following findings were given : l. The workers investigated found their working environment satisfactory, getting a mean score of 323. They also expressed a high job satisfaction with a mean score of 333. 2. They didn't have a big interest in oral health. By age group, those who were aged between 36 and 40, or who cared less about health management, showed a higher interest in oral health. Besides, the laborers who kept smoking for a longer period, or who drunk more, expressed greater interest. 3. The toothbrushing method was considered most important for periodontal health, by 45.0% of the workers, and the next most crucial one was regular dental examination, followed by refraining from smoking and staying away from sweet food in the order named. 4. Concerning daily mean toothbrushing frequency, 455% brushed their teeth three times a day on the average. More than half them didn't pay enough attention to toothbrushing. 5. Regarding scaling, the large number of the workers, 42.4%, had no experience to get their teeth scaled, 37.6%, the greatest percentage, didn't have their teeth scaled because it seemed to make their teeth painful or cold. 6. As fororal health education experience, 67.6%, the great number of them, had no experience to receive dental health education. The above-mentioned findings suggest that the cement-related workers generally neglected dental health management. They should be encouraged to correct their wrong oral health knowledge or habit to make their oral cavity more healthy. To make it happen, it's required to provide oral health education and promote organized dental health projects.

The aim of this study was to investigate the effects of food behavior and life-style behavior on the health-status of male industrial workers in the Masan region. The average age of the 173 male subjects was 42.9 years and 59% of the subjects were labor workers, 25% office workers, and 70% of them earned 1 - 1.5 million won monthly. The subjects were categorized into one of three groups : normal group, health-concerned group, and disease-suspected group classified by the criteria of the data (blood pressure, blood glucose, blood hemoglobin, serum total cholesterol, and serum triglyceride) obtained from a health examination. Forty seven belonged to the normal group, 71 to the health-concerned group, and 55 to the disease-suspected group. The health-concerned group, and disease-suspected group had significantly higher systolic and diastolic blood pressure, blood glucose, and serum total cholesterol than the normal group, and the disease-suspected group showed a significantly higher serum triglyceride level than the normal and health-concerned groups. The disease-suspected group consumed carbohydrate foods, such as cereals more frequently and protein foods such as beans and eggs less frequently than the normal group and health-concerned group. However, there was no difference in nutrient intakes among the three groups. The disease-suspected group and health-concerned group smoked more cigarettes and drank more frequently than the normal group, and the disease-suspected group exercised less as compared to the normal group. The kinds of diseases diagnosed in the disease-suspected group were hypertension, hyperlipidemia, liver disease, and neurological disease. The results of this study indicate that nutrition education and monitoring should be implemented for industrial workers to prevent chronic diseases and to reduce medical cost for the treatment of disease.

In a TV component manufacturing factory, 102 male workers aged $20{\sim}39$ years old were participated in testing for physical fitness. At the same time, worker's periodic health examination was done. Test battery for physical fitness include grip strength, trunk flexion, standing long jump, side step, single leg balance with eye close, push ups and Harvard step test. As a result of testing for physical fitness, synthetically, there is no difference between manufacturing workers and officers. By bioelectrical impedance test, it means a declining tendency to all 7 factors in the obese workers, and so, it is important for obese workers not only to promote physical fitness but also to promote health. Excluding grip strength and single leg balance with eye close, 5 fitness factors are negatively associated with degree of diastolic Blood pressure, but it is statistically not significant. And levels of sGOT & sGPT have no association with physical fitness factors.

Objectives: Although active pulmonary tuberculosis(active PTB) is manifested as one of the complications of pneumoconiosis, attacks of active PTB among patients with pneumoconiosis is still unexplored. The objective of the present study was to identify the attack rate of active PTB among workers in dusty environments who were diagnosed with pneumoconiosis. Methods: The study was performed using the results of the Pneumoconiosis Examination Council's assessment from the Korea Workers' Compensation and Welfare Service(KCOMWEL) database between January 1, 1984 and December 31, 2017. Pneumoconiosis was defined as Category 1 or more in the radiological findings of pneumoconiosis. Active PTB was defined as a positive result for active PTB in the results of the Pneumoconiosis Examination Council's assessment. Results: A total of 37,946 workers in dusty environments who received a health examination for diagnosing pneumoconiosis between January 1, 1984 and December 31, 2017 were selected as study subjects. The attack rate of active TB among subjects who were diagnosed with pneumoconiosis and those who were diagnosed without pneumoconiosis were 8.5% and 1.4%, respectively. In the multivariate logistic analysis including age, sex, radiological findings, complications, male[odds ratio(OR), 2.0; 95% confidence interval(CI), 1.4-3.1] and pneumoconiosis(OR, 6.5; 95% CI, 5.7-7.4) were associated with an increased risk of developing active PTB. Conclusions: The present study determined that dusty workers who were diagnosed with pneumoconiosis had a high rate of active PTB compared to TB patients and patients who were diagnosed with silicosis. Therefore, in addition to silicosis, it is necessary to include pneumoconiosis among the high-risk groups for TB.

Objectives : The purpose of this study was to examine about workers' oral health status and oral health behavior practice. Methods : Questionnaire survey was carried out targeting 331 workers within the industrial complex of Jeonju city in 2011. As a result of surveying and analyzing workers' oral health status, habit related to oral health, activity restriction, which is oral disease phase, and oral health practice level by using SPSSWIN 12.0. Results : 1. Workers' experience of visiting dental hospital(clinic) for the past one year was indicated to be the highest with 64.9% in the working period with 10 years-under 20 years(p<0.001). Experience of scaling was indicated to be averagely 38.8%. 2. The oral health status perceived by workers was the highest with 40.5% in 'having something abnormal'. A problem was the highest with 28.0% in 'dental caries'. A cause was indicated to be 42.6% in 'because of being naturally weak in tooth or the gum.' The biggest reason for having failed to receive the dental treatment at a proper time was indicated to be the highest with 24.8% in 'because of feeling burdensome about dental expense. '3. 58.4% of male workers were smoking. The use of dental hygiene device was the highest with 40.6% in mouth-rinse. 4. Absence caused by oral disease was indicated to be the highest with 13.8% in the household income in more than 3,500,000won, thereby having shown the significant difference(p<0.05). Early leaving was indicated to be the highest 13.9% in more than 50s age, thereby having shown the significant difference(p<0.05). Also, as for factors of absence and early leaving, a pain was the highest with 64.7%. 5. Workers' oral health practice level was the highest with 2.85 points in 'Brushing teeth before going to bed'. Conclusions : Synthesizing these findings, the oral management could be known to be made negligently in the workers with the older age, the lower academic background, and the lower income. The institutional foundation is considered to be necessary for which the oral health education can be efficiently performed in addition to a need of periodic oral examination for these classes.

This study was conducted to provide basic data for improvement of oral health of workers, by investigating oral health behaviors of industrial workers. About sixty percent(60.9%) of subjects experienced in having dental examinations and 54.3% of them didn't receive follow-up treatments after the dental examinations. Also, those who brushed teeth twice per week(58.6%) and averagely, earned 2~3 million won of monthly income(p<.01), showed a higher frequency of tooth brushing. Experienced workers(p<.01) were more interested in oral health. Those who were engaged in other jobs and had less than 10~20 years of experience(p<.05), had lots of experience in staying away from work. More aged group recognized that oral health education is necessary(p<.05). The population of oral examination and health instruction may have a favorable impact on maintenance of oral health status and improvement in quality of life.
