Objectives : This study aims to estimate the prevalence of the DSM-IV psychiatric disorders in Korean population using the Korean version of Composite International Diagnostic Interview (K-CIDI). Methods : Subjects were selected by taking multi-stage, cluster samples of 7,867 adult household residents, 18 to 64 years of age, in ten catchment areas. Total 78 trained interviewers administered the K-CIDI to the selected respondents, from June 1 to November30,2001. Results : Total 6,275 respondents completed the interview. Some 33.5% of respondents reported at least one lifetime disorder, 20.6% reported at least one-year disorder, and 16.7% reported at least one-month disorder. The most common lifetime disorders were alcohol abuse/dependence (17.24%), nicotine dependence/withdrawal (11.19%), specific phobia (5.16%), and major de-pressive disorder (4.25%). The lifetime prevalence of substance abuse/dependence (0.25%) and schizophrenia (0.16%) was very low. Nicotine and alcohol use disorder showed very high male/female ratio. Mood disorder and anxiety disorder were more prevalent among female than male. Conclusion : The prevalence of psychiatric disorders was high. In comparison with other studies, remarkable differences in distributions of psychiatric disorders across the areas and times were observed.

표본의 크기가 작을 경우 중위수의 신뢰구간 추정

박상규,함종육 중앙대학교 통계연구소 1995 統計論文集 Vol.- No.2

중위수의 신뢰구간은 일반적으로 이항분포를 이용하거나 정규근사를 이용하여 추정한다. 하지만 이항분포를 이용해서 계산할 경우 분포의 이산성 때문에 95% 혹은 90% 신뢰수준을 가지는 신뢰구간을 만들 수 없고, 정규근사를 이용할 경우 표본의 크기가 작은 경우 역시 문제가 생긴다. 본 연구에서는 표본의 크기가 작을 때 중위수의 신뢰구간을 보간법을 이용한 방법(Hettmansperger와 Sheather(1986)), 정규근사를 이용하는 방법(Sheather(1986))등을 비교해보고 Hodges-Lehmann의 추정량을 보간법을 이용해서 신뢰구간을 추정하는 문제를 제시해보고 표본의 크기가 작은 경우 모의실험을 통해 여러 확률모형하에서 신뢰구간의 포함확률을 비교한다. There are only relatively few confidence coefficients and levels available for distribution-free confidence intervals of the median for the case of the small sample sizes. This problem can be overcome by interpolating confidence intervals (Hettmansperger and Sheather(1986)) or by studentizing the median by an estimating of its standard error(Sheather(1986)). We propose another interpolating confidence interval by using Hodegs-Lehmann estimator and discuss the previously mentioned methods. We compare the coverage probabilities of the methods via simulation.

Five adults (3 cases of bilateral posterior crossbite, 2 cases of unilateral posterior crossbite) with intermaxillary discrepancy of over 5㎜ due to maxillary transverse deficiency were treated by surgically assisted rapid maxillary expansion (SARME). Bilateral maxillary horizontal osteotomies, osteotomies of pterygomaxillary junction and anterior lateral nasal wall, ans anterior palatal osteotomy were performed in 4 cases, and unilateral osteotomies in 1case, followed by palatal expansion with tooth-borne orthopedic applicance. No significant complication was observed. The mean palatal expansion was 7.2㎜ (5.8∼10.0㎜) in the maxillary first molar region. During the mean follow-up period of 4 years (5 months∼8 years 7 months), no recurrence of crossbite was observed in all cases. The SARME seemed to be a simple, stable, and reliable procedure for achieving a permanent increase of over 5㎜ in skeletal maxillary transverse width of adults.

The zinc titanate sorbents(ZTG40) were prepared and the tests for durability and attrition resistance were carried out to develop the highly effective desulfurization sorbents. In the attrition tests for ZTG40 the results showed that the attrition resistance was 94.08% and that the sulfur capacity was maintained above 15g S/100g sorbent throughout the 100-cycle test, its maximum being 23.05g S/100g sorbent. As compared to sorbents developed by the developed countries, ZTG40 showed superior performances. In the advanced countries 15g S/100g sorbent is a yardstick of excellency for the sulfur capacity of desulfurization sorbents. Therefore, ZTG40 developed in this study has the desirable physical and chemical properties for fluidized desulfurization of coal gases.

1. Objective The purpose of this investigation is to provide the youths with educational information on juvenile health within a framework of influences of smoking habits upon health, and to examine factors affecting the smoking habits by comparing the obtained information on harmful effects caused by smoking and nonsmoking practices. 2. Method Random sampling of 800 students of high school students of general education and 300 of vocational education has been put to comparison in terms of smoking group in percentage. The degree of acquaintance with the information on health on the part of smokers and nonsmokers has been compared, and the analysis of smoking - related factors has been carried out through X2 test method with an aid of the Statistics Analysis System Package Program. 3. Results 1. 434 students (39.5%) out of 1,100 students in investigation has been proved to be in the category of smokers which break down to 48.2% in high school, 35.2% in middle school, and 16.6% in elementary school in terms of their initiation stage of smoking habit. 2. The motive of their smoking is attributed to curiosity (49.3% of the students) and the amount of smoking is less than 5 cigarettes a day (53.7% of the students). 3. The most frequented place for smoking is lavatories (35.0% of the students), and the primary reason for smoking is attributed to overcoming tedium or killing time. 4. As for their understanding of and interest in smoking, 30.9% of the students responded in favor of smoking. 5. The degree of recognition of harmful ingredients in tobacco shows no difference between the smoking group and the nonsmoking group, and the degree of recognition of harmful effects of smoking upon human health has proved higher in case of the smoking group. 6. The nonsmoking group and general high school students show a higher inclination to further education in college than the smoking group and vocational high school students respectively. 7. The smoking group students show higher probability of friendship or association with opposite sex, of drinking experience, of bigger monthly allowances, and of more chances of extra - curricular activity in a student circle. Reckless preference for smoking out of mere curiosity is observed through this investigation. Positive and incessant guidance of students is recommended at home, school, and the community as well.

Acute myocarditis complicating coronary vasospasm after smallpox vaccination is very rare complication that can be generally developed within less than 30 days after vaccination. Clinically and biochemically, this disorder is often mimic and highly suggestive of acute myocardial infarction. We report 21 years old man that had a history of a smallpox vaccination 3 weeks ago and prodromal symptoms(fever, malaise etc) a few days ago. hIe visited to our hospital because of abrupt onset of severe substernal chest pain, dyspnea and diaphoresis. At admission, electrocardiography was ST elevation in lead Ⅰ, aVL, V4, V5, and V6. The CK-MB level was 68 U/L, LDH level was 760 U/L, Troponin-Ⅰ was 24.64 ng/㎖, and Troponin-T was positive. 2D-echocardiograpy was normal left ventricular function, Clinically we presumed this disorder as acute myocardial infarction and we promptly performed the coronary angiography and revealed focal spasm in distal left coronary artery territory without critical stenosis in both coronary arteries. We diagnosed this disorder as coronary vasospam complicating acute myocarditis that is different with acute myocardial infarction, and we prescribed nitroglycerin and nifedipine. After discharge, he is now well without any symptoms and has been following up monthly at our outward department for 6 months.

The purpose of this study was to evaluate the effect of immediate or delayed composite resin filling on dentinal microtensile bond strength (μTBS) after applied the adhesive. The coronal dentin of human third molars was exposed. Single-Bond or One-Step was applied on the dentin surfaces, and composite resin were constructed immediately (group 1) or 5 min., 10 min., 15 min., 20 min. and 30 min. (groups 2-6) after an adhesive was applied. The specimens were sectioned and made bar-shaped. Each surface area of them was about l ㎟. The RBS test was performed by EZ test. The results were analysed by One-way ANOVA and Tukey's test at 95 % significance level. The results suggested that the μTBS of Single-Bond to dentin was decreased when the composite resin was constructed 20 min. and 30 min. after Single-Bond was applied. But the μTBS of One-Step was not affected by delayed composite resin filling.
