        The purpose of this study was to determine the association between school administrator support as perceived by nutrition teachers (dietitians) and job satisfaction in order to provide data concerning efficient job performance of nutrition teachers, to determine effects of school administrator support on job satisfaction in nutrition teachers, and to provide basic data that could help improve school meals. Major supporters of nutrition teachers (dietitians) were chief administrators (55.3%), principals (27.2%), assistant principals (15.0%), and managers in charge (2.4%). Nutrition teachers (dietitians) scored 3.38 for perception of school administrator support, 3.66 for emotional support, 3.27 for informational support, 3.22 for instrumental support, and 3.11 for evaluation support. Support of nutrition teachers (dietitians) by school managers included emotional support (3.66)>informational support (3.27)>instrumental support (3.22)>evaluative support (3.11). Nutrition teachers (dietitians) scored 3.37 for job satisfaction, as follows: work performance (4.19)>interpersonal relationships (3.39)>job satisfaction in general (3.37)>job itself (3.29)>job environment (3.07)>performance rating and benefits system (2.70). Statistically significant correlation was observed between perception of school administrator support and job satisfaction (r= .771, p< .01). Therefore, school administrators are necessary to provide evaluative supports to nutrition teachers (dietitians), performance assessment, employee benefit packages, and improvement of school meal plans and quality.

        본 연구에서는 주름개선 화장품 원료를 개발하기 위하여 돌외 잎 70% 에탄올 추출물을 제조하여 섬유아세포 HDFn에 대하여 콜라겐 합성능을 측정하였다. 그 결과 돌외 추출물이 세포 독성 없이 농도 의존적으로 콜라겐 합성을 촉진함을 확인하였다. 돌외 추출물로부터 용매 분획 및 크로마토그래피 분리과정을 거쳐 2개의 활성 성분을 분리하였다. NMR 데이터 및 문헌치로 확인한 결과 이들은 플라보노이드 배당체인 Ombuine 3-O-rutinoside(1) 및 Quercetin 3-O-rutinoside(2)로 규명되었다. 섬유아세포의 type I procollagen 생합성에 미치는 영향을 분석한 결과 상기 화합물은 농도 의존적으로 콜라겐 합성을 촉진함을 알 수 있었다. 본 실험 결과는 화합물 1과 2를 함유한 돌외 추출물의 주름개선 화장품 소재로서의 개발 가능성을 보여주고 있다.
