PURPOSE: The objective of this research is to investigate the effectiveness of mental practice on function and muscle activation of upper extremity (UE) in stroke patients. METHODS: The mental practice was conducted on 12 subjects for 10 minutes and the related existing work treatment for 20 minutes. The evaluation for the function of UE proceeded with Fugl-Meyer assessment of motor function (FMA) and muscle activity analysis instrument. Furthermore we analyzed patients' reaching activity by two stages, reaching phase and returning to original position phase. RESULTS: According to the research results, the subjects' upper limb function improved in all of the measured items and the total scores after the mental practice (p<.05). In muscle activity, CCR value was used to efficiently analyze the patients' reaching activity in the two stages of reaching stage and returning to the original position phase. While the elbow movement only had a bit of positive change (1.1%) in the reaching stage, both the shoulder (-12.3%) and elbow (-18.2%) movements had a positive change in the returning to original position phase. CONCLUSION: This research confirmed that the mental practice is effective for the enhancement of UE function for stroke patients. The result of this research can contribute to the progress of mental practice in clinical environment.

This study compares, analyzes and reevaluates color conditions and images before and after the execution of the 7th curriculum with elementary schools in Gwang-ju Metropolitan City based on the fact that color among physical environments of elementary classrooms has an important influence on children's emotion and draws problems and aims to accumulate the basic materials for preparing guidelines of improving color environment at general classrooms of elementary schools. Consequently, according to color conditions, major colors on ceiling and wall were high brightness/nigh chroma of Y and YR line regardless of division of grades and other color factors of classroom showed that wall and ceiling used similar colors, but brightness was higher after change than before it. In evaluation of color images, lower grades showed negative color images such as 'common,' 'rustic,' and 'strange' before change, but they showed positive color images after change such as 'clean,' 'unique,' and 'soft'. But, most of higher grades showed negative reactions before change such as 'common,' 'strange,' and 'rustic' and they showed positive reactions after change only in such items as 'clean,' 'warm,' and 'unique', but Indicated negative reactions in remaining items such as 'strange,' 'rustic,' 'stiff,' and 'artificial'. Accordingly, in using colors for lower grade classroom, arrangement of colors through adjustment of brightness and chroma between ceiling, wall and other components based on coloring of high brightness and low chroma of similar colors should be considered and for higher grade classroom, arrangement of colors of unique images of mid-brightness/mid-chroma among warm color lines of similar colors should be examined.

In this study, the concept of environmental-friendly architecture, where environment is importantly regarded as a design concept in modern architecture and the meaning of boundary are examined, To apply properly design methodologies along with the importance of environment, the concept of environmental-friendly architecture should be first correctly established. And as the recent rapid development of technologies provides new possibilities for environmentally-friendly architecture, it is needed to have a new boundary concept and the interpretation of the meaning of boundary differentiated from the one of existing architecture. Recently the meaning of boundary is expanding its range to the relations with its neighboring environment beyond the relations with in and out of a space and has also the role as a medium for exchange and communication instead of breaking-off. Therefore, the boundary of environmental-friendly architecture alongside physical boundary is extended to the area for communication. Here, a basic boundary of architecture is maintained, but its meaning and expressions get natural shapes. The study deals with the analysis of the concept of environmental-friendly architecture and its changes from the perspective of times, environment and social backgrounds and seeks its appropriateness centered on environmental-friendly architecture Since 1980s when the issues of human and environment were raised in earnest.

태풍이 해양을 이동할 때 해양환경은 물리 생물학적으로 한반도 주변해역에 영향을 미친다. 태풍이동의 결과로써 해양의 수직적 혼합과 용승작용은 해양 표층수 냉각을 유도하고 태풍의 경로에 따라 식물플랑크톤의 증가를 초래하며, 태풍 전과 후의 해양환경은 해양표층의 생물학적 변화에 중요한 역할을 했다. 비록 태풍 이동의 원인으로 해양 표층수의 냉각이 확대되지만, 엽록소, K490, SST와 같은 다른 물리-생물리적 반응은 서로 다른 경향을 나타낸다. 본 연구의 목적은 한반도 주변해역에 영향을 미치는 태풍 이동경로와 해색센서에 의해 관측된 해양환경변수를 비교하는데 있다. 부유물질, 흡광계수(K490), 엽록소와 같은 해양환경변수는 2002년부터 2005년 MODIS 자료가 적용되었다. 태풍이동 후 동해에서는 평균 엽록소 농도가 1-4배 증가하였고, 태풍 이동경로를 따라 태풍 이후 MODIS 엽록소의 평균 농도가 증가하였다. 그러나 제주도 해역은 동해역과 반대의 경향을 나타내었다.

The purpose of this study is to analyze the changes in turnover intention according to the level of Burn out and the mediating effect in fire officer. Higher levels of emotional labor and turnover intention resulted in higher levels of burn out(p<0.05). We used the logistic regression analysis to compare change of turnover intention according to the level of burn out. In logistic regression analysis, largest mediating factor were working days per week, the number of moving case per a day, physical condition, emotional labor and the odds(Likely to with high turnover intention) was down by 38.9% after adjustment for mediating factors. The results of this study indicate that emotional labor was negatively impact on burn out in fire officer. To reduce the burn out and the turnover intention, it is necessary to do more efforts to improve work environment (working days per week, the number of moving case per a day and emotional labor) and management personal factor(physical condition) for the fire office should be made to reduce such negative effects.
