연구배경: 호기말에 흉부 촬영을 시행하면 폐 내의 공기의 부피가 감소되어 폐 감쇄도가 증가한다. 이런 폐 감쇄도의 변화가 국소적으로 저하되는 공기 가둠 현상에 대해서는 일부 연구들이 있었으나 전체 폐의 전반적인 감쇄도 변화에 대한 연구는 거의 없고, 특히 정상인을 대상으로 한 연구는 거의 없다. 저자들은 호흡기 질환이 없으며 폐기능 및 흡기 전산화단층촬영이 정상 소견이고 호기 영상에서 국소적인 공기 가둠 현상이 없는 100명을 대상으로 연구를 수행하였다. 방 법: 흉부 전산화단층촬영 영상에서 24개의 지점을 정하고, 흡기 및 호기 시 각 지점에서 폐 음영도를 측정한 후 호기말 폐 감쇄도 증가와 흡연량, 연령 사이의 상관 관계를 알아보았다. 결 과: 연구 대상 100명의 연령은 중앙값 49.0세(범위 25~71세)였고, 평균 흡연량은 $22.5{\pm}17.0$갑년이었다. 연령과 폐 감쇄도의 증가 사이에는 유의한 음의 상관관계가 있었으며 이는 흡연의 효과를 보정하였을 때에도 유지되었고, 연령을 기준으로 세 군으로 나누어 폐 감쇄도의 증가 정도를 비교하였을 때에도 유의한 차이가 있었다. 흡연량과 호기말 폐 감쇄도의 증가 사이에는 유의한 음의 상관관계가 관찰되었으나 연령을 보정하였을 때에는 유의성이 감소하였다. 결 론: 흡기-호기 시의 폐의 전반적인 감쇄도 변화 정도는 연령과 상관관계가 있으며, 노화를 반영할 가능성이 있다.

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.

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.
