This study was carried out to obtain informations on the variations of oil content and fatty acid composition among 90 Korean perilla collections. Average oil content of 90 perilla collections was 44.2% with a range from 29.7% to 61.9%. Perilla collections with late-maturing, super-large seed and gray seed coat showed higher oil content than other types in general. Average saturated fatty acid content in perilla oil was 9.0% with a range from 8.2% to 10.7%, while average unsaturated fatty acid content varied from 89.3% to 91.8% with a mean of 91.0%. Contents of saturated and unsaturated fatty acids were not related to maturity. There were no differences in the contents of saturated and unsaturated fatty acids according to maturity. Linoleic acid and linolenic acid contents were the highest in the super large-sized group(15.5%) and in the large-sized seed group(61.4%), respectively, while contents of fatty acids among the perilla collections were variable with different seed coat colors. Most of the traits studied were not significantly correlated with oil content, but linoleic acid($\omega$ 수식 이미지-6) content was negatively correlated (r=-0.217*) with linolenic acid(ω-3) content.

This experiment was conducted to screen useful herbicides for Populus euramericana Gainer nur-sery at the Chungbuk Forestry Experiment Station in 1988. Soil surface treatment of 11 herbicides was made on May 19 after planting Populus euraneicana G. cuttings. Digitaria sanguinalis(L.) Scopp, Chenopodium album var. centrorubrum Makino, Portulaca oleracea L., Eleusine indica(L.) Gaertner and Echinochloa crusagali (L.) Beauv. var. praticola Ohwi were dominant weeds in the nursery. Among herbicides tested, alachlor G, alachlor+pendimethalin G, Metolachlor+prometryn EC and oxyfluorfen EC were effective to control both grasses and broad-leaf weeds effectively, but the falter two chemicals resulted in severe damage to Populus euramericana. The growth of cuttings measured by basal diameter and height showed no significant difference among treatments and he-rbicides except oxyfluorfen. Significant correlations were observed between weed coverage 2 weeks after herbicide treatment and number of weeds 1 month and 3 months after herbicide treatment. Also, number of weeds after 1 month was significantly correlated with that of 3 months after herbicide treatment.

It has been rapidly given to the importance of the embodiment of the efficient computer systems in university education. Since the recent trend of the adoption of the openess policy in university education systems significantly affects on the realization of the embodiment of the efficient computer systems which is very essential to promote the international competition in many areas of university education. So it is greatly needed that our Soonchunhyang university must have the following principles for the embodiment of the efficient computer systems. (1) It is required that the appropriate computer education and the good quality of research environment must be given. (2) The establishment of the synthetic computer network system for efficient the university administrations is needed. (3) It is needed to establish the computer system for the consideration of the future performance. (4) It is also needed to improve the organization and the administration systems of the university computer center. (5) It is required on the establishment of the local area network(LAN) systems in the Soonchunhyang university, and the LAN must be connected to other outer national and international computer systems. And we propose the following requirement for the establishment of the convienent computer systems in our university and we have been greatly though about the significant change of the environment in university computer system. [1] The subject of the basic computer must become as the required subject for the all students in the curriulum. [2] The new computer systems both in hardware and software must be introduced. [3] It is needed to the change of the present name of the university computer center into the university information and computer center. And its organizations must be furthur developed [4] The training center for the university emploee is also needed. [5] The establishment of the database systems for the automtion of the university administation is needed. [6] It is strongly required on the establishment of the local area network system in the Soonchunhang university to connect the Bitnet and the Internet through the Hankook communication. [7] The computerization for the central library is needed. The indepent local area network system for the library is also needed to establish the own database system. Finally we hope that the LAN will be connected to the national wide library computer system.

업종별 음식점에서 사용중인 주방기구 가운데 개숫물중에 존재하는 세균들을 분리·동정한 결과, 한색음식점에서 37균주, 일식음식점에서 23균주, 및 중식음식점에서 33균주가 분리되었고 이들 중 한식음식점에서 E. coli 등 16균주, 일식음식점에서 Listeria sp. 등 20균주, 중식음식점에서 Micrococcus sp. 등 15균주를 각각 동정하였다. 이들 세균들은 업종별 음식업소에서 주로 사용되는 색품재료에 존재하는 세균들과 밀접한 관계가 있는 것으로 밝혀졌고 E.coli와 같은 일부 세균들은 주방의 불결한 환경이나 종사자로부터 오염된 것으로 추정되었다. 업종별 음식점에서 사용중인 개숫물, 행주, 칼, 및 도마에 존재하는 세균의 분포는 일반세균수 및 대장균수가 모두 2월에서 8월까지 점점 증가하다가 11월에는 다시 감소하는 경향을 보였다. 특히 이같은 경향은 일반세균은 개숫물에서 대장균군은 칼에서 가장 뚜렷하게 나타났다. 따라서 식중독 발생 가능성이 가장 높은 여름철에는 칼, 도마 등 주방기구들은 정기적으로 열탕소독하는 철저한 위생처리가 필수적인 것으로 생각되었다. Thirty-seven, twenty-three, and thirty-three bacterial strains were isolated from dish-washing water which was selected as a kitchen supply commonly loaded the highest level of bacteria among various supplies using at Korean style, Japanese style, and Chinese style restaurants. Among these isolates, sixteen strains including Esherichia coli, twenty strains including Listeria sp., and fifteen strains including Micrococcus sp. were identified from Korean style, Japanese style, and Chinese style restaurants, respectively. This result suggested that most isolated bacteria were closely related to bacterial flora of raw food materials used in each style of restaurants and others could be contaminated from the surrounding environment and the employees. Total and coliform bacterial counts distributed in dish washing water, wiping cloths, knives, and cutting boards used at different types of restaurants were gradually increased from February to August and then decreased until November. This changing tendencies of total bacterial counts and coliform group counts were obvious in dish-washing water and in knives, respectively. Therefore, kitchen supplies such as wiping cloths, cutting boards, and knives should be treated carefully with hot water of above 45℃ at every certain period of time to kill some of these potential hazardous bacteria and to prevent outbreaking foodborne-illness by them, especially during Summer.

The human papillomavirus (HPV) are wide spread in the world, causing proliferation of epidermal and mucosal surface. Certain papillomaviral types are oncogenic in vivo and in vitro. HPV DNA has been detected in most of cervical lesions such as condyloma acuminata, dysplasias, and invasive carcinomas. The materials for this study consisted of 5 dysplasias. 5 squamous cell carcinomas, and 5 exocervix for control, that resected for definite treatment of uterine disease at Chosen University Hospital from January, 1991 to December, 1993. All cases were performed of in situ hybridization for HPV DNA type 6/11, 16, and 18. And also immununohistochemical stain for panel of monoclonal cytokeratin (CK) antibodies were done. The result obtained is as fallows : 1. HPV DNA type 6/11 are detected in all dysplasias. HPV DNA type 16 and 18 are detected in squamous cell carcinomas. 2. Stratifed squamous epithelium of exocervix are positive staining for CK 1, CK 5/6, CK 8, CK 13, CK 14, and CK 19. HPV DNA type 6/11 infected cells are positive for CK 1, CK 13, CK 14, CK 17, CK 18, and CK 19. HPV DNA type 16/18 infected cells are positive for CK 1, CK 5/6, CK 10, CK 13, CK 14, CK 17, CK 18, and CK 19. In conclusion, HPV infection of uterine cervix is associated with change of normal cytokeratin expression pattern. Dysplastic cells are changed of CK 5/6, CK 8, CK 17 and CK18. Squamous cell carcinoma cells are changed of CK 8, CK 17, and CK 18.

연약지반 터널 굴차시 실드공법은 근접 구조물 안전에 유용한 공법이다. 하지만 실드 터널 공법은 터널 주변 지반의 변형을 최소화 할 수 있는 장점을 가지는 반면 테일 보이드(Tail Void)에 그라우트된 주입재가 경화되기 전에 발생하는 지반 변형은 피하기 어렵다. 본 연구에서는 테일 보이드로 인한 인접 구조물의 침하를 억제하는 방법중 하나인 마이크로파일(micropile)의 영향을 모형실험을 통하여 규명하였다. 기초적인 실험 결과로써 마이크로파일 보강시 마이크로파일의 효과적인 설치방향과 침하 억제비를 밝혔다. In soft ground tunneling, shield method is very good for safety of neighboring structures. Although shield tunnel method has the merits to minimize the deformation of ground around tunnel, ground deformations occurred until the material grouted in tail void hardens are inevitable. In this study, the effects of micropile used as one method to restrain the settlement of neighboring structures by the tail void are studied by laboratory model tests. As a basic test result, the effective direction of micropile and the restraint rate of settlement by micropile reinforcement are known.
