의료근접도 및 용이성이 의료이용에 미치는 영향 -연세건강공제회원의 외래의료이용을 중심으로-
오희철,Oh, Hee-Chul 대한예방의학회 1979 Journal of Preventive Medicine and Public Health Vol.12 No.1
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.
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.

믿음을 가질 성향, 성향적 믿음, 폐쇄 버전의 쉬운 지식 문제
오희철 범한철학회 2022 汎韓哲學 Vol.106 No.3
코언은 기초 지식 구조를 가진 지식 이론들이 쉬운 지식 문제에 직면하게 된다고 주장한다. 필자는 폐쇄 버전의 쉬운 지식 문제에 대한 새로운 해결책을 제시할 것이다. 우선 필자는 알려진 함축하에서의 폐쇄와 연역적 폐쇄를 살펴보고 두 종류의 폐쇄 중에서 후자가 폐쇄 버전의 쉬운 지식 문제와 관련되어 있다는 것을 보여줄 것이다. 이어서 필자는 연역적 폐쇄를 통해 폐쇄 버전의 쉬운 지식 문제가 무엇인지 선명하게 제시할 것이다. 그리고 필자는 성향적 믿음과 믿음을 가질 성향을 활성화된 믿음과 구분함으로써 폐쇄 버전의 쉬운 지식 문제에 대한 한 가지 해결책을 제안할 것이다. 마지막으로 필자는 이 해결책에 제기될 수 있는 가능한 세 가지 반론을 살펴보고 이에 대한 답변을 제공할 것이다. Stewart Cohen argues that theories of knowledge with a basic knowledge structure fall victim to the problem of easy knowledge. I propose a novel solution to the closure version of the problem. First, I examine in detail closure under known entailment, and deductive closure, and then show that the latter is related to the closure version of the problem. Second, with deductive closure, I make it clear what the closure version of the problem is. Third, I propose a solution to the closure version of the problem by distinguishing dispositions to believe and dispositional beliefs from occurrent beliefs. Finally, I consider three possible objections to this solution, and then provide answers to them.
