  • 이 연구는 ISO/TC54 전문위원회(Shanghai, Sep. 14-15, 2010)의 결정에 따라 국제규격 초안으로 제안된 ISO/DIS (Draft International Standard) 25157-resolution 385 중국산 쿠스이(苦水)형 장미(Rosa sertata ${\times}$ Rosa rugosa) 정유의 기체 크로마토그래피 분석표에 대한 국제 6개국 전문가 실험실간 재현정밀도 시험 (round-robin test: RRT)의 하나로 수행되었다. GC-FID로 분석할 때 비극성인 SPB-1 컬럼에서는 총 179개 성분, 중간 극성의 DB-624 컬럼에서는 165개 성분, 극성 Supelcowax-10 컬럼에서는 총 162개 성분을 분리하였다. ${\beta}$-Citronellol (41.6~46.7%)과 geraniol (9.7~11.0%) 및 nerol (3.4~4.5%)이 쿠스이형 장미 정유의 주성분이었다. SPB-1 컬럼과 DB-624 컬럼에서는 ${\beta}$-citronellol과 nerol성분 피크가 서로 분리되지 않고 중첩하였으나, Supelcowax-10 컬럼에서는 두 성분을 분리할 수 있었다. Phenethyl alcohol의 경우 정지상 극성이 커질수록 머무름 시간이 길어짐을 확인하였다. 그런데 거의 대부분의 특성 성분들의 머무름 시간은 중국측이 ISO/DIS 25157에서 제시한 것과 일치하였으나 극성 컬럼으로 분리한 phenethyl alcohol의 머무름 시간의 경우 중국측이 제시한 것 보다 큰 차이를 보였다. 동시에 불가리아산 장미(Rosa damascena Miller) 정유와 향수에 대한 기체크로마토그래피 분석표도 비교 분석하였다. 불가리아 장미 정유의 특성 아로마 성분 함량이 중국산 쿠스이형의 함량보다 더 많았다.

  • To identify and evaluate the benzidine-DNA adducts in liver and bladder, we exposed the 80 ppm benzidine to 40 sprague-dawley rats by drinking water for 4 weeks(6.2 mg/kg body wt./day). Only one benzidine-DNA adduct was found at the same site of thin layer chromatogram of $^{32}$ P-postlabeling method in the liver and bladder of exposed rats. So we know the DNA adduct formed at liver and bladder were similar to each other, which was N-(deoxyguanosin-8-yl)-N'-acetylbenzidine. Relative adduct labeling(RAL) of DNA adduct was similar to each other for 1 and 2 weeks, but that in liver was significantly higher than in bladder for 3 and 4 weeks. RAL$\times$10$^{9}$ of DNA adduct were 84.45$\pm$11.31 and 152.8$\pm$5.53 in liver, and were 24.76$\pm$7.06 and 38.00$\pm$10.57 in bladder for 3 and 4 weeks, respectively. Regression equation between liver and bladder was Y=-3.801+2.507 X(r=0.6036, p<0.01). In conclusion, benzidine-DNA adduct formed in liver was significantly higher than that in bladder, with the similar compound structure in sparague-dewley rates treated benzidine in drinking water.

  • Most existing residential environment of disabled people has made them exposed to the risk of safety accidents, and therefore hinders their independent living. In this regard, the importance of desirable residential environment has emerged. Some preceding studies have addressed the characteristics of disabled people's residential environment plan; however, the information on what environmental benefits are offered through such characteristics is insufficient. This study aims to analyze the housing design guidelines for disabled people in respect of the benefit of disabled people who are actual users. In this study, essential design guidelines for disabled people verified through expert workshop panel was analyzed based on user benefit theory. According to the study results, the total guidelines have the most characteristics supporting behavioral facilitation, and mainly consist of physiological maintenance characteristics related to disabled people's health and safety. Also, it is founded that environmental affordance essentially required depending on each spatial function was different. The ratio of physiological maintenance item is high in access route, unlike living room, kitchen and bed room where behavioral facilitation is especially emphasized. These findings can be utilized as basic data for customized residential environment plan to realize residential welfare for disabled people.

  • According to the 2005 Korean census, the 65 and over population now exceeds 9.5% of the total population and is growing rapidly. Meeting elderly environment and care needs of this rapidly growing segment of the population becomes a major challenge for public policies and planners. Since great deal amount of elderly will reside in their houses, aging in place concept becomes important. For the success of aging in place, the quality of individual house unit, community support systems, and quality of senior center of the community are crucial. Since elderly environments and facilities serve not only medical and/or care programs but also social activity program in aging society, senior centers need to promote social activities and other care programs. The purpose of this study is to analyze characteristics of environmental affordance of a well received senior center in Tokyo, Japan. In order to analyze the characteristics, Murtha & Lee user benefit criteria and Lawton's environmental affordance approaches were used. As results, design characteristics and interior elements which provide environmental affordance were enumerated by type of space. Based on needs and user benefit criteria, those features were analyzed. This study shows design characteristics, elements, and attributes which are well received and utilized by elderly users.
