1991년3월부터 8월사이에 대구시에 소재한 1개의 대학병원의 종합검진센타에 내원해서 종합검진을 받은 남자 422명(69.9%)과 여자 182명(30.1%)을 대상으로 하여 심헐관계질환의 위험요인들의 전체적인 분포를 보았다. 평균 연령은 남자가 43.3(표준편차, 10.3), 여자가 44.4(표준편차, 10.8)였다. 남자에서 연령에 따라 0.05 수준에서 통계적인 유의성을 보인 위험인자는 혈청 총콜레스테롤(TC). 트리글리세라이드(TC), 고밀도 지단백콜레스테롤(HDL), 저밀도 지단백콜레스테롤(LDL), 수축기혈압, 비체중, A형행동양상이었으며 생활습관으로서는 음주, 흡연, 규칙적인 운동, 우유와 커피섭취, 수면 등이었다. 여자에서는 TC, TG, LDL, 수축기와 확장기혈압, 비체중 그리고 커피섭취와 수면 등이었다. 남자에서 총콜레스테롤의 평균은 181.7mg/dl(표준편차, 32.2), 여자는 182.5mg/이(표준편차, 42.2)였다. 대부분의 위험인자들은 구미의 수준에 미치지 못했으나 남자에서 흡연율이 전체적으로 61.8%로 높으 수준이었으며 특히, 20~29세가 72.9%, 30~39세가 75.2%로서 다른 연령군에 비해 상대적으로 높았다. 여자에서는 전체적으로 6.0%에 지나지 않았다. 확장기혈압 90mmHg 이상을 고혈압자로 정의했을 때의 유병률이 여자 전체대상자에서 24.7%로 높았으며 50-59세는 표본수가 적어서 문제가 되었으나 53.1%였다. 어떤 인구집단내에서 총콜레스테롤의 평균이 200mg/dl 미만이면 고혈압과 흡연의 인구집단의 수준에 관계없이 관상동맥질환(coronary heart disease)의 발생은 드문 것으로 보고가 되고 있으므로 당분간 관상동맥질환 발생률의 급속한 절대적인 증가는 힘드리라 사료된다. 그러나 이러한 결과는 본 연구의 대상자들이 대표성을 지니지 못하며 건강검진센터에 자발적으로 내원한 사람들이므로 해석에 주의를 요한다. Authors examined the distributions of the risk factors for the coronary heart disease in the 422 male (69.9%) and 182 female (30.1%) visitors to the health examination center of a university hospital located in Taegu March to August 1991. Mean age of males was 43.3(standard deviation, SD 10.3) and that of females was 44.4(SD 10.8). Total cholesterol(TC), triglyceride (TG), high-density lipoprotein and low-density lipoprotein cholesterol(LDL), systolic blood pressure, Quetelet index, and Type A Behavior Pattern, and some of life habit variables(alcohol intake, smoking, regular exercise, milk and coffee intake and sleeping) were statistically significant in age groups of the males(P<0.05). In the females, TC, TG and LDL, systolic and diastolic pressure, Quetelet index, coffee intake and sleeping were statistically significant in age groups (P<0.05). Mean of total cholesterol was 181.7㎎/dl(SD,32.2) in males and that of females was 182.5㎎/dl(SD,42.2). Most of the risk factors levels were lower than the Euro-Americans', while smokers were high with 61.8%, especially 72.9% in 20-29 age group and 75.2% in 30-39 age group in males. In females, smokers were just 6.0%. Hypertensives defined by more than 90mmHg diastolic pressure were 24.7% in females, particularly 53.1% in 50-59 age group, but size of the strata was rather small(N=49). In the light of the report that coronary heart disease is uncommon irrespective of population levels of smoking and hypertension, where average total blood cholesterol level in a population is low(<200mg/dl), it is not likely that the absolute increase of the number of the coronary heart disease will increase markedly in the near future. But cautions should be exercised in interpreting the results of this study due to the lack of representativeness and volunteerism. .

Authors administered a questionnaire to 300 clients visited to the K University Hospital during August in 1992 to investigate the degree and related factors of consumer's satisfaction with the hospital services. Clients consisted of 82 in-patients and 158 out-patients, 52.4 percent of them was male. Four dimensions of satisfaction were assessed which were medical management, administration, environment and attitude. In-patients reported as dissatisfied with the waiting time during receipt, investigative medical procedures and pharmacy (64.7%), lack of conveniency facilities for patients and their guardians(48.8%) and provision of conveniency facilities in the ward(42.4%), unsanitary state of out- and in-hospital(41.5%). Out-patients reported dissatisfaction with the course of medical management and the time needed(70.3%), the waiting time during receipt, investigative medical procedures and pharmacy(68.3%), lack of conveniency facilities for patients and guardians(42.4%). But both in-patients and out-patients were satisfied with medical equipments, doctor's diagnosis reliability and medical effects, technician's attitude more than 50%. Canonical correlation analysis was done to find related sociodemographic factors to the four dimensions of satisfaction. Of the four canonical functions, the first was only statistically significant in in-patients. Its eigen value was 0.56 and its canonical correlation coefficient was 0.60. Satisfaction with environment and medical management was selected as important concept in dependent variables. Standardized canonical function of environment and medical management were 0.76 and 0.35 respectively. It was related with woman with high educational attainment and increasing number of hospital visits. In out-patients, the first, second and third function were statistically significant and their eigen values were 0.18, 0.4, 0.08 respectively which were small compared to those of in-patients. Their canonical correlation coefficient were 0.40, 0.35, 0.28 respectively. Low degree of environment but high degree of medical management satisfaction was noted in the first function which was related with old age, woman and professional occupation. Low degree of satisfaction with administration(second function) was related with city resident, non-professional occupation and young age. High degree of medical management but low degree of administration satisfaction(third function) was related with surgical visitor, man and non-professional occupation. The direction of hospital managerial strategies could be planned and general characteristics of dissatisfactory clients might be suggested with these results.

Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.

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.

This thesis studies on the pattern recognition algorithms in Fourier domain and proposes two improved methods. Three methods are studied on and the performances of them are compared and applied to the pattern recognition of printed numbers in the car-licence plate, and two improved methods are proposed in this application field. The first method which uses the correlation in Fourier domain, and the second method uses only the central part of correlation-images, and the third, phase-only-correlation method, uses only the phase of images. The conventional method which uses the correlation as it is shows the low performance, the proposed method adopted the algorithm which uses the central part only in the correlation-images. In particular, the performance of this method can be improved by applying the algorithm to the black and white images after preprocessing. As well as this method, for the phase-only-correlation method, the performance of recognition can be increased by multiplying an appropriate constant to the amplitude before inverse Fourier transformation. The phase-only-correlation method recognizes the patterns by the magnitude of peak which appears at the center of the image which is obtained by inverse Fourier transformation of the correlation images which consists of phases only. Two methods also shows the high performance in the recognition of numbers which includes noises. In the experimentaion, 10 standard images and 10 number-images in the car-licence plate are used. The black-and-white images from the images and the images with Gaussian noises are also used. The experimental results show the proposed methods are very valid to the recognition of numbers in car-licence plate and they shows higher performance for black-and-white images.

The purpose of the study was to see how prevalent the risk behaviors of korean university students using Youth Risk Behavior Surveillance System(YRBSS) developed by the Centers for Disease Control and Prevention(CDC). Translation and modification for Korean students of the YRBS were carried out March 2000 and the modified YRBS were administered to students of 4-year college in Daegu metropolitan city. The number of students used at final analysis was 619(male : 212(freshmen: 101, senior students : 111) female : 407(freshmen : 146, senior students : 261)) Over 50% of university students rarely or never used safety belt and there were no significant difference between freshmen and .senior students. 363 of students had ridden a bicycle during 12 months preceeding the survey. Of these students, almost student(male : 99%, female : 100%) were rarely or never wore a bicycle helmet. During the 12 months preceding the survey, 22.8% male freshmen had felt so sad or hopeless almost every day for 22weeks in a row that they stopped doing some usually activities and there were no significant difference between freshmen and senior students. Male student in grades 2. 3 and 4(89%) were significantly more likely than freshmen(42%) to have ever tried cigarette smoking. Almost male students had had >1 drinks of alcohol during their lifetime(lifetime alcohol use) and almost male freshmen(%%) and senior student(%%) had 2 1 drinks of alcohol on 2 1 of the 30 days preceding the survey(current alcohol use). These results suggest that some risk behaviors be very prevalent in a korean university students and priority health-risk behaviors, which contribute to the leading cause of mortality and morbidity among youth and adult, often are establish during college age, extend into adulthood, are interrelated.

Autor adiministered a questionnaire to and drew the blood of 426 healthy male adults ages 40-60 years who visited the Dongsan Hospital in 1988 for the biannual physical checkcup to examine the relation between anger-coping types and serum total cholesterol. The Harburg model for anger-coping types using spouse and boss as the power figures was employed. Mean serum total cholesterol was 192.4mg/dl(standard deviation, SD 34.0) and mean age was 49.0(SD 5.8). In spouse situation, mean of total cholesterol of the anger-in was 196.5mg/dl(SD 34.0) compared with 191.0mg/dl(SD 34.0) of the anger-out/medium. Mean of the anger-in was 194.5mg/dl(SD 33.9) while that of the anger-out/medium was 191.6mg/dl(SD 34.9) in boss situation. In total suppressed anger index, mean of the anger-in was 197.0mg/dl(SD 35.6) compared with 191.7mg/dl(SD 33.8) of the anger-out/medium. But there was no statistical significance in all of three instances(P>0.05). Controlling for age and Quetelet index did not alter the statistical significance. The prevalence(total cholesterol≥200mg/dl) odds ratios of anger-in to anger-out/medium were 1.10(95% confidence interval, CI 0.70-1.74) in wife situation, 1.41(95% 0.91-2.19) in boss situation, and 1.37(95% CI 0.78-2.42) in total supressed anger index, respectively indicating higher prevalence in anger-in than anger-out/medium. All the odds ratios included one in their 95% confidence intervals. Controlling for age and Quetelet index with multiple logistic regssion resulted in slight change of odds raios in each of hypothetical situations.

We evaluated CT findings of the small cell carninoma, which presented as a solitary pulmonary nodule at the periphery of the lung parenchyma. Of pathologically-proven 45 patients with small cell carcinoma, 10 patients was included in this study, who had a solitary, peripheral lung nodule at distal portion of the subsegmental bronchus. We retrospectively reviewed clinical data and CT findings including size, location, margin, enhancement pattern, lymph node enlargement, metastasis. Peripheral small cell carcinomas were 22.2%(10/45). All masses had well-defined margin and lobulated margin was seen in 7 patients. Mean diameter was 3.8cm (2.5-7.0cm). Enhancement pattern were homogeneous in 3 cases and inhomogeneous in seven. Calcification or air-bronchogram was not present, and focal cavitation was seen in one case. In five, only lung mass was present, and lung mass with lymph node enlargement was seen in one. distant metastasis without lymph node enlargement was noted on two patients and another two patients showed lymph node enlargement and distant metastasis. Peripheral small cell carcinoma is not rare(22.2%). Most frequent CT finding is a well-defined, lobulated mass with inhomogeneous enhancement, these findings would be helpful in differentiating small cell carcinoma from other neuroendocrine tumors when differentiataion is difficult cytologically.

Objectives : In order to evaluate the relationship between daily mortality and air pollution in Deagu for the period by the data from January 1993 to December 1997. Methods : Deaths from accident (International Classification of Disease, Revision 9 ; 800∼999 and Revision 10 ; V01-Y89) were excluded. Daily counts of deaths were analysed by general additive poisson model on the current day to 5 days before death, with controlling for effects of year, season, weather, weekday and holiday. The air pollutants examined included total suspended particulate (TSP), sulfur dioxide (504, nitrogen dioxide (NO2 , carbon monoxide (CO) and ozone (O3). Results : Mortality was associated with NO2, SO2 and CO in the air. Total mortality was estimated to increase by 1.6 %(95 % CI 0.3∼3 %) with each 10 ppb rise in NO2 on the current day and the preceding 1 day, 9.4 %(95 % CI 7∼13 %) with each 100 pub rise in SO2 and 2.7%(95% CI 0.1∼5%) with each 1 ppm rise in CO on the current day. The NO2 was more evident for the elderly who were 65 years and more. Cardiovascular-specific mortality was associated with the levels of CO on the current day. Respiratory-specific mortality was associated with the levels of TSP and NO2 5 days before death. Excess mortality risk is clearly evident in the upper range of NO2 levels and increased monotonically with NO2. Conclusions : This study suggested that the air pollution status below the current Korean ambient air quality standard might have an adverse effect on daily mortality. Then, it is impertive that the strategy for control of the air pollution-related daily mortality should be developed.
