최희숙,Choi, Hee-Sook 한국약제학회 1991 Journal of Pharmaceutical Investigation Vol.21 No.4
The structural specificity and the chemical dynamics between ${\beta}-cyclodextrin$ and aspirin were studied by FT-IR UN, $^1H$ NMR. $^{13}C NMR$. and FAB-MS spectroscopy in solution and solid state, A stable solid inclusion complex was prepared by the recrystallization method, From the spectral changes of the host and guest molecules, orientational preference for binding in the cyclodextrin cavity was determined.

The molecular nature of aspirin hydrolysis was studied using cyclodextrin as a biomimetic model for esterase. Cyclodextrin was selected for this purpose because it meets the necessary requirements for the hydrolysis study. Dissociation constants and catalytic rates were obtained under alkaline conditions by the kinetic method.

This study is to find out the learning strategy to meet learning motivation for attaining desired goal by keeping the learning motivation through the analysis of the relationship between learning characteristics, learning strategy, and learning satisfaction in synthetic model, and make the plan for teaching to enhance learning satisfaction and attain the learning goal by concrete practices in the learning course. The subject of the research was 415 persons who were the students enrolled in S University in Seoul and adult learners registered in the Credit Bank System at the University annex lifelong education institute, and the analysis of structural equation model was applied. As a result of the research, first, in the relation of learning motivation and learning strategy, social success motivation appeared in giving significant impact on resources management strategy, and the motivation of intellectual satisfaction appeared in giving significant impact on cognition strategy and resources management strategy. Second, in the relationship between learning motivation and learning satisfaction, intellectual satisfaction appeared in giving significant impact on learning satisfaction, while social success motivation did not give significant impact on learning satisfaction directly. Third, in the relationship between learning strategy and learning satisfaction, metacognition strategy appeared in not giving significant impact on learning satisfaction, while cognition strategy and resources management strategy gave significant impact on learning satisfaction Last, there was the difference from the relationship between learning motivation, learning strategy, and learning satisfaction per institution (the university students or the learners of the credit bank). 본 연구는 학습 특성과 학습전략 및 학습만족도와의 관계를 종합적인 모형으로 분석하여 학습동기를 유지해서 원하는 목표를 달성하기 위해서는 학습전략의 활용과 학습동기에 맞는 학습전략은 무엇인지, 그리고 이에 따른 학습과정에서의 구체적인 실천방법을 마련함으로써 학습만족을 높이고, 학업성취로 이어질 수 있는 교수개입의 방안을 마련하는데 있다. 연구대상은 서울소재 S대학교의 일반학생과 대학부설 평생교육원 학점은행제 등록 성인학습자 총 415명이며, 구조방정식모형 분석을 실시하였다. 연구결과 첫째, 학습동기와 학습전략의 관계에 있어서, 사회성공 동기는 자원관리 전략에 유의한 영향을 주는 것으로 나타났으며, 지적만족 동기는 인지 전략과 자원관리 전략에 유의한 영향을 주는 것으로 나타났다. 둘째, 학습동기와 학습만족도의 관계에 있어서는 사회성공 동기는 학습만족도에 직접적으로 유의한 영향을 주지 못하는 반면, 지적만족 동기는 학습만족도에 유의한 영향을 주는 것으로 나타났다. 셋째, 학습전략과 학습만족도의 관계에서는 인지 전략과 자원관리 전략은 학습만족도에 유의한 영향을 주는 반면, 메타인지 전략은 유의한 영향을 주지 못하는 것으로 나타났다. 마지막으로 기관별(일반학생, 학점은행학생)로 학습동기, 학습전략, 학습만족도의 관계에서 차이가 있었다.

미역 추출액의 식품가공 적성을 검토하기 위하여 Brookfield digital viscometer(SPDL21)를 사용하여 전단속도를 달리하면서 정상유통특성을 조사하였다. 100℃, 2시간 열수 추출한 미역 추출액의 유통특성을 측정한 결과는 항복응력을 가진 pseudoplastic 거동을 나타내었다, 유동특성과 온도의 관계를 알기 위하여 온도 변화에 따라서 겉보기점도와 1/ T의 관계를 도시한 결과 겉보기 점도는 회전속도 10rpm에서 온도가 증가함에 따라 감소하는 경향을 보였으며 활성화 에너지는 1.15 kcal/mole로서 온도의 의존성이 있는 것으로 나타났다. For the purpose of investigation to the food processing fittness of the sea mustard aqueous extracts, the steady shear flow have been measured over a wide range of shear rate using a Brookfield digital viscometer(SPDL21). The rheological behaviors of the sea mustard aqueous extracts which were extracted at 100℃ for 2 hours exhibited pseudoplastic behavior with yield stress. In the test of the relationship between temperature and apparent viscosity of samples at 10 rpm decrease along with the increment of temperature. The sea mustard aqueous extracts appeared greatly temperature dependent characteristics(Ea = 1.51 kcal/mole).

A survey was carried out to investigate consciousness level of health. A total of 499 people living in Seoul and the vicinities were asked to fill out the questionnaire during the period from the October 1997 to the January 1998. Among the 532 answers collected 33 was imcompleate data, and 499 answers were used for the statistical analysis by using SPSS program. The most worried disease was cancer(27.6%), indigestion(23.0%), liver trouble(14.8%) and high blood pressure(14.8%). The perception of Korean on health and food habit indicated that food habit was considered the most important factor for the maintenance of health, as appeared in 28.9% of the subject. Eighty-seven percent of the respondents thought that health food is necessary for the health.
