This study was to investigate the structural behavior of braced-frame systems with slit damper. For this study, push-over analysis was carried out to investigate the difference of structural behavior between the braced frame system without slit-plate dampers and the braced frame system with slit-plate dampers. The braced-frame systems with slit plate dampers were more effective than the braced-systems without slit-plate dampers: (1) The plastic hinges which were happened at damper were decentralized each story so that the plastic deformation of the main frames were decreased. (2) The ductilities of the former structure were increased.

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.

Background : Mucins possess the unique function of protecting and lubricating the epithelial surface and other important functions such as call growth, direct implication in the fetal development, the epithelial renewal and differentiation, the epithelial integrity, carcinogenesis, immune regulation, cellular adhesion and metastasis. Purpose : This study was done to provide the significance of alteration of MUC1 and MUC2 expression in colorectal adenocarcinoma, A series of 131 colorectal adenocarcinomas including 11 mucinous carcinomas were screened immunohistochemically for their expression of MUCI and MUC2, Materials and mehtods : Of 131 carcinomas, 76 (58,5%) were MUCI positive and 91 (68, 9%) were MUC2 positive, In normal colonic goblet cells, MUCl was not expressed but MUC2 was expressed in cytoplasm, Conclusion There were up-regulation of MUCI and down-regulation of MUC2 in colorectal carcinomas, The frequency of MUC2 positivity according to differentiation was statistically reliable.
