We need to think that space is not static but dynamic because it becomes wide and narrow, newly appears and disappears by human's behavior. Generally such movement in a space is a thing of feeling and dynamic about movement. But it is extending the experience of the subject by scientific technique's development and anticipation about the feature. The practical movement is actively introduced into architecture and interior design scope and occurs a trial about this movement. By using four elements -a form, hue, movement, light- kineticism becomes visual arts united with art and science. It recovers the art's sociality and arises participation of spectators. In the environment and art field kineticism is not simple ostentation but a current trial for human's mind and sensitivility. Kineticism is four-dimensional space considered by human's experience and is related to an observer, or experiential subject of space. Now the space except human's mind feature re-illuminates kineticism, that is, the field of the formative arts in the early part of the 20th century and gets to be 'the consensus space'.

Background and Aims: Herbal drugs and traditional medicines have lately attracted considerable attention by global pharmaceutical corporations because the conventional chemical drugs didn't work well for many chronic diseases or intractable diseases. The government of Korea is also supporting to develop the new drug which is high value added product, and the natural medicine including herbal medicine(or Traditional Korean Medicine) have a significant presence in this field. non-clinical pharmacology/toxicology study and clinical trial are the two major criteria which estimate efficacy and safety for registration of new drugs. All of the pharmaceutical companies producing herbal medicine and the academic and the academic world of Tradition Korean Medicine have the will to develop new herbal drugs, but there are obstacles that they have neither experience nor guideline about clinical trial. Therefore for developing new herbal drugs, it is necessary to research the present conditions and comprehensive systems about clinical trial in Northeast Asian countries China, Taiwan and Japan because they have the common background with Korea in traditional medicine fields. Methods : The present state of clinical trial for herbal medicine in Korea was investigated. And then, those in China, Taiwan, Japan was also investigated. Results and conclusions : There are significant differences among 4 Southeast Asian countries Korea, China, Taiwan and Japan each in present condition, purpose, involved comprehensive system including legislation, and actual operation of clinical trial for traditional medicine.

A field trial of norfloxacin on bovine 206, swine 222 and poultry 205 with respiratory diseases and diarrhea was conducted from Sept 1, 1990 to Jan 30, 1991 in Inchon and Kyonggi-do. The results are as follows. 1. Guinea pigs and rabbits were dosages 10 and 20 times normal. Ten days of observation saw no side effect. 2. Oral treatment on bovine, swine and poultry showed a curing rate of 82.00∼89.06%(Mean 86.00%), compared with 87.27∼96.36%(Mean 92.24%) by Injection. 3. The curing rate was 81.92% by the fourth treatment. 4. The curing rate with and without the use of adjuvant was 80.00∼100% and 83.60∼93. 10%, respectively, for swine, and 81.82∼100% and 82.00∼97.14% for bovine. 5. The curing rate was more dependent on seriousness of illness, environment and time than age. 6. The main disease causing bacteria of bovine respiratory diseases： Haemolytic Sta 27.62%, Haemolytic Str 33.33%, sum of this bacteria is 60.95%, diarrhea: Haemolytic coliform 80.20%, swine respiratory diseases； Haemophilus Spp 20.95%, Haemolytic Sta 72%, Haemolytic Str 21.90%, Sum of these bacteria is 68.57％, diarrhea; Haemolytic coliform 57.26%, poultry respiratory diseases； mycoplasma Spp 29.52%, Haemolytic Sta 13.33％, Sum of this bacteria is 42.85%, diarrhea； Haemolytic coliform 53.00%. 7. The curing rate of norfloxacin by species of strain, the unidentified bacteria on bovine respiratory diseases was the lowest with 77.78％, the others ranged from 84.21％ to 100％ with most of them over 90%. 8. The loss of clinical sign on bovine and swine was the highest when after 2∼4 application. 9. In terms of antibiotic sensitivity test, norfloxacin was the highest with 84.62∼100％ (mean 90.09％) among eight bacterias, only 5 of 15 antibiotics had a sensitivity of over 56.25%, showing a high degree of tolerance.

Objectives . In large-scale field trials, randomization by cluster is frequently used because of the administrative convenience, a desire to reduce the effect of treatment contamination, and the need to avoid ethical issues that might of otherwise arise. Cluster randomization trials are experiments in which intact social unit, e.g., families, schools, cities, rather than independent individuals are randomly allocated to intervention groups. The positive correlation among responses of subjects from the same cluster is in matter in cluster randomization. This thesis is to compare the results of three randomization methods by standard error of estimator of treatment effect. Methods : We simulated cholesterol data varing the size of the cluster and the level of the correlation in clusters and analyzed the effect of cholesterol-lowering agent. Results : In intra-cluster randomization the standard error of the estimator of treatment effect is smallest relative to that in inter-cluster randomization and that in individual randomization. Conclusions : Infra-cluster randomization is the most efficient in its standard error of estimator of treatment effect but other factor should be considered when selecting a specific randomization method.

대학도서관 평가는 대학도서관의 수준 향상을 위한 기본전략이라고 할 수 있다. 이에 대통령 직속 도서관정보정책위원회에서는 2005년도에 한국교육학술정보원에서 개발된 대학평가지표를 이용하여 시범평가를 함으로써 대학도서관들의 의견을 수렴하여 평가지표의 타당성과 실효성을 검증하고 향후 적용 방안에 대한 시사점을 얻고자 하였다. 그 결과 평가항목 및 지표부분에 있어서 시정사항이 요구되었으며, 본 연구는 시범평가에서 나타난 문제점을 해결하고 대학도서관에 적용할 수 있는 평가지표를 제시하고자 하였다. 평가지표 세부수정내용은 첫째 평가분야를 7개 분야에서 재화자원과 시설자원을 '예산 및 시설자원'으로 통합하여 6개 분야로 줄였다. 둘째, '도서관경영' 분야의 '이용자헌장과 '기획' 항목을 제거하고 '도서관 자체평가' 항목을 추가하였으며, '정보자원' 분야에서 '비도서 및 기타자료' 평가항목을 추가하였다. 셋째, 재화자원 및 시설자원을 통합하여 '예산 및 시설'로 하였으며 평가지표는 예산항목과 도서관시설로 수정하였다. 넷째, '정보이용' 분야에서 '장서회전율'을 '장서이용'에 통합시키고. '정보서비스'분야의 '도서관 이용율' 항목을 '정보자원' 분야로 이동시킨 후 '이용율'로 항목이름을 바꾸었다.
