The researcher intended to investigate the rate of absenteeism and other related statistics among the workers in a steel and iron industry with the criteria and the recommendation of the International Association on Occupational Health. With the well designed questionaire and interview, 1,882 workers were surveyed from July the 24th to the 28th, 1978. The results were as follows; The workers who experienced absence were 16.8% in July. The rate of frequency (spells) was 3.24, the duration was 4.65, the frequency (persons) was 345.20, and the lost time was 1.27. 41.0% among the absentee experienced sickness absences and the rates of sickness absence were as follow; the frequency (spells) nab 1.34, the duration was 2.29, the frequency (persons) was 101.06 and the lost time was 0.63, respectively. The main causes of sickness absence were general symptoms, such as fatigue (50.8%) and gastro-intestinal symptoms (13.8%). The frequency of sickness was highly correlated to the frequency of drinking, the amount of smoking, the physical work-load and the amount of drinking, which was analysed by the stepwize multiple regrssion analysis. The multiple R due to the above mentioned four variables was 0.320 and the R square was 10.3%.

In order to investigate dietary risk factors for hypertension in th elderly, dietary intakes and dietary habits of 405 elderly subjects, aged 60-94, were assessed by the questionnaire, anthropometric measurement and a 24-hour dietary recall. The prevalence of definite (>95mmHg for diastolic or>160mmHg for systeolic blood pressue) and borderline(90-95mmHg for diastolic or 140-160mmHg for systolic blood pressure) hypertensive subjects 33.3% and 19.3%, respectively. The distribution of the subjects for Body Mass Index(BMI), waist-hip ratio, and alcohol consumption were significantly different among definite, borderline, and normal groups(p<0.05). The distribution of the subjects for smoking, exercise, and preference of salty food were not significantly different among definite, borderline, and normal groups(p>0.05). From the generalized logistic regression analysis of the risk factors for the hypertension, the subjects with over 27 of BMI had significantly higher risk of hypertension. Alcohol consumption and preference of salty food were significant risk factors of hypertension in the elderly. Dietary risk factors for the hypertension that had significant relationship to the hypertension were intakes of potassium, calcium, phosphate, sodium, vitamin B1, niacin, and folate. There was no significant difference of consumption frequencies of food and dish among definite, borderline, and normal groups(p>0.05). The amount of intakes for cereals and grain product, bean and their products, eggs were significantly different among definite, borderline, and normal groups(p<0.05). In summary, the amount of dietary intakes to hypertension in elderly population. Longitudinal studies for dietary risk factors on incidence of hypertension are needed in general population, especially in the elderly.

This study investigated the purpose of internet usage among high-school seniors and how their psychological, behavioral, and interpersonal adjustment levels were affected by the amount of lime spent on the internet. The subjects were 572 high-school seniors who participated in the first panel of Korean Education Empolyment Panel (KEEP). The participants were divided into 2 groups: low use group using the internet for less than 30 minutes a day and high un group using the internet for more than 3 hours a day. The adjustment levels of these two groups were compared. The findings were as follows. First, the high use group used the internet to enjoy games, whereas the low use group used the internet to seek schoolwork-related information. Second, the high use group had more negative self-concepts and experienced more stress regarding economic hardship than the low use group. Finally, the high use group watched T.V. longer, studied less, and had more experiences of deviant behaviors, such as bullying, smoking, drinking, and sexual relations.

Purpose: This study investigated the factors that influence depression in adolescents diagnosed with asthma in South Korea, providing basic data supporting efforts to improve adolescents' mental health. Methods: Multiple regression analysis was conducted on 4,020 subjects who had been diagnosed with lifelong asthma among the 57,303 respondents to the 15th Korea Youth Risk Behaviour Web-Based Survey from 2019. Results: The participants were more likely to have depression if they were female, in middle school, their academic achievement was poor, they were drinkers or smokers, if they felt a very high amount of stress, and if they experienced very inadequate recovery from fatigue. Adolescents with asthma were 9.00 times more likely to experience depression when they felt a very high amount of stress (95% confidence interval [CI]=5.51-14.69, p<.001) than when they felt no stress. Conclusion: Given these factors, measures to improve the mental health of adolescents should be developed and expanded, especially to decrease their stress levels. A separate program that is different from the school's regular health curriculum should be developed to manage the stress levels of adolescents with asthma, such as an after-school program or a program conducted at a local community centre.

The government continuously increases cigarette price to reduce the smoking rates. Opinions of cigarette makers and Ministry of Health and Welfare on the effect of cigarette price hike are sharply opposed. This dispute is important because there is possibility of additional increase of cigarette price by 500 won. Therefore, as an inquiry into existing studies for the effect of cigarette price hike on tobacco product, namely analysis of the effect of cigarette price hike consumption, we empirically analyzed the effect of cigarette excise tax hike through establishing improved analytic models considering time trend. As a result, it is substantiated that time trend in the effect of cigarette excise tax hike is certainly exist and early impact is heavy. However, the amount of cigarette consumption is recovered to the level of the average in 5 months. Since it is proved that the long term effect of cigarette price hike is immaterial, health authority should reconsider the plan of additional raising cigarette price by 500 won.

Nitric oxide of gas phase in cigarette smoke was conveniently determined by Chemiluminescence NO analyzer with 20 ports rotary type smoking machine Data are presented to support this observation. On the basis of this method the amount of NO in the smoke from nonblended and commercial cigarettes were estimated. Gas phase NO concentration in main stream smoke was correlated well with the nitrate levels in tobacco leaves, but there was no correlation with the tar yields. In consequence, it would be considered that the methodology in this study provided simple and rapid quantification for NO in cigarette smoke.

This study was conducted to estimate the dental caries experience, oral hygiene status and the factors influencing the dental disease in the smoking adolescents and to provide the baseline data for managing smokers efficiently. We recruited 156 smokers(male: 106, female: 50) in middle, high school students in 5 day Non-smoking program in seoul city and 176 non-smokers(male: 64, female: 112) by matching method for considering sex and age from June 1 to August 31 2009. Data on general characteristics, basic oral health care, smoking factors, self-efficiency, control of oral health, oral health promotion behavior, knowledge of oral health were collected by a questionnaire interview. DMFT index, DT index, MT index, FT index, Plaque index, Calculus index were calculated by the oral examination. The results of this study were as follows. 1. Dental clinic visit(p < 0.05), self-perception of oral health status(p < 0.001), oral health concern (p < 0.01) in non-smoker group were significantly higher than that of smoker group. 2. self-efficiency(p<0.05), oral health promotion behavior(p < 0.05) in non-smoker group were significantly higher than that of smoker group. 3. DT index, Plaque index, Calculus index in non-smoker group was significantly lower than that of smoker group(p < 0.0001). 4. The fewer smoke amount, the lower DT index(p < 0.05), Plaque index(p < 0.01), Calculus index(p < 0.001). 5. It was significant correlated among DT index and self-efficiency, oral health promotion behavior, control of oral health. 6. In multiple regression analysis, oral health promotion behavior, Plaque index was proved as a significant factors related with the degree of dental caries experience in smoking adolescents. In other word, the higher oral health promotion behavior, the lower Plaque index, the fewer DT index.
