Accessibility to medical facilities and personnels has been known as one of important determinants of medical care utilization. This study attempted to identify the effects of medical accessibility in terms of geographical distance and occupational opportunity to the medical utilizations. Two-year-experiences of Yonsei University Health Insurance Cooperatives were used as the sources of data. Out patient utilization patterns of 713 members sampled from 4,352 members of Health Insurance Cooperatives were analyzed in order to identify the effects of medical accessibilities. Findings: 1 Average clinic visit rate of Yonsei Health Insurance is 1.66 per person per year. 2. The utilization rates of geographically more accessible group were 33% higher than that of less accessible group. 3. No marked difference in clinic visit rate were observed between medical and non-medical personnel and their family members. 4. Clinic visit rates among occupationally accessible group were slightly higher than those of less accessible. The utilization rate was more sensitively changed by the insurance policy changes in occupationally accessible group.

The purpose of this study is to examine the relationship between pesticide use and mortality, and cancer mortality which are recognized as health hazards of pesticides. Data were analyzed from a cohort of 6,066 people aged fifty-five or over and who have been residing in the main island of Kangwha county. Death certificates, computerized citizenship registers searches, and household interview survey lead to get more than ninety-seven percents follow-up rate for the first five year observation period. Important findings are as follows : 1. Age specific mortality rates of pesticide users are significantly lower than those of pesticides nonusers. The SMR of male is 0.80, and 0.58 for females respectively probably due to healthy worker effects. But, age specific cancer mortality rates are significantly higher than those of pesticide nonusers (SMR=1.59) in males. This finding is not observed in females (SMR=0.85), however. 2. Logistic regression analyses showed that self-reported health status, drinking, and smoking histories in male are significantly associated with total mortality rate. The histories of pesticide use are also calculated to be highly associated with cancer mortality as in univariate analyses in males. In female, self-reported health status, age of first delivery are found to be significantly related to total mortality rate. Only drinking history is calculated to be associated with cancer mortalities in females. Data from further observation of 'Kangwha cohort' and indepth analyses of these are highly expected.

이 글에서는 게티어 사례가 무엇인지에 대한 재그젭스키의 설명이 가진 문제점에 대해 살펴볼 것이다. 우선 재그젭스키의 게티어 사례 만드는 법에 대해 간략히 살펴볼 것이다. 다음으로 재그젭스키의 게티어 사례 만드는 법이 게티어 사례들을 만드는 데에 필요하지도 않고 게티어 사례들을 만들기에 충분하지도 않다는 것을 보여줄 것이다. 마지막으로 재그젭스키의 게티어 사례 만드는 법이 가진 이러한 문제점이 게티어식 인식적 행운에 대한 오해에서 비롯되었다는 것을 보여줄 것이다. This paper examines problems for Zagzebski’s explanation of the defining feature of Gettier cases. Firstly, it briefly deals with Zagzebski’s recipe for constructing Gettier cases. Secondly, it is argued that this recipe is neither necessary nor sufficient to construct Gettier cases. Finally, it is argued that these problems that this recipe has result from misunderstanding of Gettier-style epistemic luck.

To show the distribution and change of blood pressure according to age and to find factors affecting the level of blood pressure in primary school children, a follow-up study was conducted from 1986 to 1989 on 401 first grade children attending primary school in Kangwha County in 1986 and their parents. The blood pressure of the children was significantly increased according to age. The average annual increase was 1.8mmHg in systolic blood pressure and 2.5mmHg in diastolic blood pressure. The level of blood pressure did not show any significant difference in both sexes. Among children who were at or above the 80th percentile of blood pressure in the first grade, 35 and 30% of them have remained at the same level of systolic and diastolic blood pressure respectively in the fourth grade. But we could not find any significance in the tracking of blood pressure of children who were at or above the 90th percentile of blood pressure in the first grade. Weight and pulse rate were shown to be significant factors affecting systolic blood pressure in children of both sexes and mother's blood pressure and skinfold thickness were also affected systolic blood pressure in girls. The variables significantly affecting diastolic blood pressure were arm circumference and pulse rate for boys and height and pulse rate for girls.

Objectives: To evaluate the learning achievement and satisfaction levels for the Field Epidemiology Specialist Training Program (FESTP), on infectious disease control between March 19 and October 31, 2002. Methods : The FESTP was designed as a set of 84 hours curricula including lectures, discussions, self-studies, and field practicals, and organized both centrally and locally by the Division of Communicable Disease Control of the National Institute of Health and 11 universities. Before and after the program, a questionnaire survey on the educational need (49 items) and satisfaction (15 items) was conducted on 484 trainees, who were responsible for communicable disease control and immunization at 242 regional health centers. The data were analyzed with paired t-tests for comparison of the educational needs between the pre and post scores. Results : The average score for satisfaction was 3.06 out of 5.0; with relatively higher scores for sincerity (4.10) and professionalism (4.01) of the tutors, adequacy (3.54) and clearness (3.51) of the evaluation criteria, usefulness (3.54) and fitness (3.52) of the contents, but with relatively lower satisfaction for schedule (2.96) and self-studies (2.91). The average for requirement for education improved, as shown by the decrease from 2.72 to 2.22 (p<.0001) with the biggest decrease in the outbreak investigation from 2.60 to 2.08. Conclusion : The FESTP was evaluated as being effective, the trainees showed moderate satisfaction and decrease educational needs. However, the actual schedules and self-studies should be rearranged to improve the satisfaction level.

N/A The transmission of hepatitis C virus (HCV) by direct percutaneous exposure to blood is well documented by both epidemiological and experimental studies. Persons commonly considered at increased risk of acquiring HCV include blood and blood product recipients, parenteral drug users and health-care workers. These groups, however, only account for half of the hepatitis C cases reported, and many cases of HCV infection associated with nonparenteral routes have been reported but there have still remained controversy, and the epidemic outbreak of hepatitis C through nonparenteral routes have been reported extrernely rarely in the world. Most of epidemiologic studies of the hepatitis C had been reported before the developement of the various diagnostic tools such as anti-HCV test, detection of HCV RNA using polymerase chain reaction and direct genomic sequencing. These newly developed diagnostic methods may open the new era of the hepatitis C and the remained controvery is expected to be solved in the near future. We report the epidemic outbreak of hepatitis C in 13 cases in Nam-Chang-Lee from April to October in 1989. On epidemiologic studies, no case had identifiable parenteral transmission routes. The monthly incidence shows unimodal and highly comprewed pattern suggesting that this outbreak was transmitted within a short period and through the same transmission route, possibly nonparenter- al route. The diagnosis of the hepatitis C was made by the anti-HCV (positive rate: 81.8%) and the detection of the HCV genome. The genomic sequences of N51 region of the isolated two cases showed 84-96% homology to the Japanese type and 87-98% to the Taiwan type but only 70-71% to the prototype. This study may suggest the evidence of epidemic outbreak of hepatitis C transmitted via nonpar-enteral route. But further epidemiologic characterizations of this epidemic may provide insight into the routes of' HCV transmission and further studies are required to determine the clinical significances of different types of HCV.

N/A Background/Aims: Chronic hepatitis type B is highly-prevalent in Korea. However, few studies about its natural history and prognostic factors have been presented until now. The natural course and long-term prognosis of chronic hepatitis type B varies greatly, and this diversity makes it difficu]t to predict the clinical course of individual patients. The histologic finding is known to be a important prognostic factor. Thus we conducted this study to evaluate the natural history and prognostic factors of chronic hepatitis type B in Korea. Methods: The authors analyzed the clinical courses of 147 patients with clinicopathologically proven chronic hepatitis type B through long-term follow-up from the time of the initial biopsy according to histologic classification. 15 patients had chronic persistent hepatitis(CPH). 61 patients had chronic active hepatitis without bridging necrosis(CAH-BN). 46 patients had chronic hepatitis with bridgung necrosis(CAH+BN). 25 patients had chronic active hepatitis with early cirrhotic change(CAH+LC). They were followed for 24 to 150 months(mean 70.8(+25.8)). Results: The probability of developing cirrhosis in chronic hepatitis type B was 0%, 2%, 10%, 18%, 23%, 28%, 37%, 49%, 54% in 1 year to 9 years, respectively. The 5-year cumulative probability of developing cirrhosis was 9% in CPH, 14% in CAH-BN, 22% in CAH+BN, and 55% in CAH+LC. The significant prognostic factors of developing cirrhosis were age(p<0.01) and histologic classification(p<0.001). The probability of developing decompensated cirrhosis in chronic hepatitis type B was 0%, 0%, 0%, 1%, 5%, 13%, 17%, 28%, and 32% in 1 year to 9 years, respectively. The probability of developing hepatocellular carcinoma(HCC) in chronic hepatitis type B was 0%, 0%, 0%, 1%, 3%, 3%, 6%, 8% and 8% in 1 year to 9 years, respectively. The significant prognostic factor of developing HCC was age. Conclusions: The results of this study explored the natural history and prognostic factors of chronic hepatitis type B. 5-year cumulative probability of developing cirrhosis, decompensated cirrhosis and HCC was 23%, 5% and 3%, respectively. Histologic classification and age were significant prognostic factors for the development of cirrhosis. Age was a significant prognostic factor for the development of HCC.

植物凝集素 Sophola japonica와 赤血球에 의한 사람 唾液의 型分類에 關한 硏究

吳熙哲,文國鎭 고려대학교 의과대학 1990 고려대 의대 잡지 Vol.27 No.3

Since it was discovered that the human saliva could be classified by using the serological characteristics of Sophola japonica extract, agglutination inhibition tests of phytagglutinin, Sophola japonica , and human red blood cells were carried out, using 300 human saliva specimens. The relationship of the newly classified saliva types with the established saliva, blood, and serum types was compared statistically. The results obtained could be summarized as follows : 1. Human saliva could be classified into two groups. One group inhibited the agglutination activity of Sophola japonica extract to human red blood cells and the other did not. Among the investigated 300 human saliva specimens, the frequency of the former was 21% and the latter was 79%. 2. The classification and distribution of new saliva types, inhibitor and non-inhibitor, showed no constant relation with those of the known saliva types, secretor and non-secretor, and the saliva types which were classified by the agglutination inhibition pattern of Sophola japonzca extract and human blood cells. 3. The classification and distribution of the new saliva types showed no constant relation with those of the known blood groups, such as ABO, MN, H and Cl, respectively. 4. There was no serological relationship between the human serum types classified by IPO, NPO and ICO, NCO with phytagglutinin mentioned above.
