유성진,권석만 서울대학교 심리과학연구소 2000 心理科學 Vol.9 No.1

본 연구는 범불안장애의 핵심적 증상인 걱정(worry)과 관련된 성격특징을 탐색하고자 하였다. 선행연구에서 걱정이 많은 사람들의 성격적 특성으로 시사된 4가지 성격특징, 즉 비관주의, 완벽주의, 불확실성에 대한 인내 부족, 문제해결의 자신감 부족을 경험적으로 검증하고자 하였다. 아울러 강박 성향자 및 우울성향자의성격특징과의 비교를 통해, 걱정이 많은 사람들의 고유한 성격특징을 알아 보고자 하였다. 332명의 대학생 자료를 분석한 결과, 걱정이 많은 사람들은 4가지 성격특징을 지니는 경향이 나타났으며 특히 불확실성에 대한 인내 부족과 완벽주의가 높은 상관을 나타냈다. 아울러 걱정이 많은 사람들은 강박성향자와 비교했을 때 비관주의와 문제해결의 자신감 부족에서 상대적으로 높은 상관을 나타낸 반면, 우울성향자와 비교했을 때는 완벽주의에서 상대적으로 높은 상관을 나타냈다. The aim of the present study is to investigate personality traits related to worry which is an essential symptom of generalized anxiety disorder. Worriers were proposed to have personality traits of pessimism, perfectionism, lack of tolerance to uncertainty, and lack of confidence on problem-solving. In addition, proper personality traits of worriers were explored through the comparisons with obsessive-compulsive symptoms and depressive symptoms. The results from 332 university students appeared that worry was significantly related to the four personality traits, in particular, showing high correlation with lack of confidence on problem-solving and perfectionism. In particular, worry showed closer relationship with perfectionism than did depressive symptoms, whereas worry showed stronger relations with pessimism and lack of confidence on problem-solving than did obsessive-compulsive symptoms.

유희정,황성훈,홍진표,김헌수,이철,한오수 大韓神經精神醫學會 2000 신경정신의학 Vol.39 No.1

본 연구는 IMF에 관련된 경제적 스트레스가 정신 건강에 미치는 영향과 그 과정을 밝히기 위해 설계되었다. 스트레스 과정에 관여하는 요인으로 사회적 지지와 문제 해결 양식, 그리고 무망감을 도입했으며, 이들에 의해 스트레스의 영향이 매개되는지를 검증하였다. 경제적 스트레스의 수준에 따라 표집된 221명의 일반인들을 대상으로 우울, 불안, 신체화, 적대감, 사회적 지지, 그리고 문제 해결 양식 등을 측정하였다. 가정한 대로 실직으로 대표되는 경제적 스트레스는 정신 건강에 부정적 영향을 미치는 것으로 나타났다. 그 구체적인 양상을 살펴보면 다음과 같다. 먼저, 사회적 지지는, 높은 스트레스 조건에서 증상의 발현을 억제하는 완충 효과가 있음이 입증되었다. 두번째로, 남성이 여성에 비해 경제적 스트레스의 부정적 영향에 더 취약한 것으로 나타났다. 세번째, 경제적 스트레스는 문제 해결 양식의 다양한 구성요소중 문제 해결에 대한 무기력감에만 영향을 미치는 것으로 나타났다. 네번째, 무망감은 경제적 스트레스와 정신 건강간의 관계를 매개하는 변인임이 인과모형 검증을 통해 확인되었다. 끝으로, 이러한 결과가 스트레스 개입 프로그램 개발을 위한 이론적 기초를 제공한다는 의의가 있음을 논의 했고, 본 연구의 몇 가지 한계점을 지적하였다. This study was designed to investigate the influence of the so-called IMF-related economic stress upon the mental health and to analyze the process of the influence. As the possible variables moderating the stress process, social resource, problem solving style, and hopelessness were included. 221 male and female subjects were recruited according to the intensity of economic stress and classified into four groups(employees of solid companies, employees of the companies at risk, short-term unemployed and long-term unemployed). Relevant measures including economic stress scale, selected SCL-90R subscales(somatization, depression, hostility, anxiety), social support scale, problem-solving scale, and job hopelessness scale were administered. As assumed, it was proved that economic stress had adverse effects on the mental health. In addition to this basic causal relationship, moderating effects of several variables were found as follows: First, social support had the buffering effect upon the economic stress. That is, strong social support played the role suppressing the development of psychiatric symptoms under high stress. Second, men were more vulnerable to the adverse effects of economic stresses than women. Third, economic stresses had influence on the helplessness concerning the problem solving. However other problem solving strategies such as creative style, approach style, avoidance style, etc were proven to have no relationship with the economic stress. Fourth, in the analysis of unemployed group, it was found that hopelessness mediates the relationship between economic stress and mental health. In conclusion, the clinical implications of such findings in economic stress process were discussed and several limitations and the suggestions for future researches were also addressed.

An inflammatory difference between the gastric antrum, body and fundus was studied in 39 H.pylroi positive duodenal ulcer and 29 H. pylori chronic gastritis patients. Also we studied correlation of H. pylori colony count and inflammatory severity. Patients with newly diagnosed duodenal ulcer and chronic gastritis were endoscoped and two biopsy secimens each taken from the antrum, body and fundus. Although intestinal metaplasia in antrum and inflammatory activity in fundus were more severe in chronic gastritis patients. another inflammatory difference was equally likely to be found between two groups. There was no definite histological inflammatory difference between duodenal ulcer and chronic gastritis patients. A positive correlation was found between the number of H. pylori and the severity of inflammation.

The purpose of this study is to find out the effectiveness of the HAPPY DREAM HM-206DB applied to the patients with Frozen Shoulder by measuring, assessing and analyzing the changes in pain and range of motion(ROM). Surveyed from Mar. 2007 to Dec. 2007 were 10 patients suffering from Frozen Shoulder. After HAPPY DREAM HM-206DB, the pain were measured and analyzed by means of MPQWL, VAS-I and VAS-U, while ROM was measured and analyzed by using Goniometer. The major findings from this study are as follows; 1. There was significant decrease in the MPQWL after HAPPY DREAM HM-206DB applied(p<.001). 2. There was significant decrease in the VAS-I(intensity of pain) after HAPPY DREAM HM-206DB applied(p<.001). 3. There was significant decrease in the VAS-U(unpleasantness of pain) after HAPPY DREAM HM-206DB applied(p<.001). 4. There appeared, however, significant increase in ROM(abduction, external and internal rotation) after HAPPY DREAM HM-206DB applied(p<.001). From the above outcomes, it was revealed that HAPPY DREAM HM-206DB application has proven to reduce the pains, exercising huge influence to increase ROM. It is, therefore, suggested to continue and expand the study on the cure of Frozen Shoulder and to motivate patients, rehabilitation specialists, and health management specialists etc. to consider HAPPY DREAM HM-206DB application as safest and most efficient pain remedy.

김진상,유성환 인제대학교 2009 仁濟論叢 Vol.24 No.1

This study is concerned about seismic performance evaluation of seismically isolated structures. Firstly, sorts of various base isolation system were explained and basic concepts and principles of seismic isolation structure were described. Also, through investigation about existing seismic performance evaluation method of U.S.A and Japan, characteristics and problems of each country were grasped. Lastly, model buildings were analyzed to evaluate seismic performance by non-linear time history analysis. According to analysis results, displacements of 1st floor and top floor were very similar. From this results, it is possible to guess that the behavior of upper parts of structure was very similar to that of rigid body due to establishment of base isolation system. Also, as story drift decreased, shear force of 1st floor column decreased to a considerable degree. Although seismically isolated structures usually has a prolonged cycle , according to analysis result, period of this model structure of steel 20-stories is similar with that of non-seismically isolated structure. This results show that when low or middle stories scale is suitable on strong base site, base isolation system behaves most efficiently.
