The word Euisaeng (醫生) is shorthand the Euihaksaengdo (medical cadets), that means has been changed according to the times. Throughout the Goryeo dynasty, Euisaeng was not mean medical student, but also primary healthcare. Existing research on Euisaeng of Joseon dynasty has been grouped together, despite the identity and characteristic differences between the central and local Euisaeng. The authors have separated the two, and a review of the literature focuses on local Euisaeng. The authors found the following facts in this study. First, status of Oebang-euisaeng (local medical cadets) was declined in the latter than in the early Joseon. Second, Oebang-euisaeng of the late Joseon was Layered Hyang'ri. Third, The local medical cadets was important, the role of primary healthcare. On the other hand, The central medical cadets was important, the role of a student learning medicine.

The research aim is to classify biotope types of rural eco-villages designed by ministry of environment and analyze landscape ecological characteristics of them. This information would provide information on eco-villages' potential and specific needs to improve landscape ecological structure of eco-villages. Two eco-villages, designated by ministry of environment, in Yoocheon-ri and Sanduk-ri were selected and the landscape ecological metrics used in this study were Area, Shannon diversity index, Shape index, Distance index. The results are as follows. 1) There were five biotope types in large-scale classification, 13 biotope types m Sanduk-ri and 9 biotope types in Yoocheon-ri in middle-scale classification, 31 biotope types in Sanduk-ri and 24 biotope types in Yoocheon-ri in small-scale classification. 2) In the case of area, artificial biotope types, such as artificial forest, agricultural irrigation canal, wet paddy, dry paddy and residential area, covered more than 80% of total area. However, natural biotope types, such as natural forest, river, reservoir, covered just more than 10% of total area. In details, an orchard (26.69%) was the dominant biotope type, followed by artificial forest (19.10%) in Sanduk-ri and the first most abundant biotope type was artificial forest (49.71%), followed by wet paddy (15.95%) in Yoocheon-ri. 3) The result of Shannon diversity index indicated that Sanduk-ri (2.158) had more heterogeneity landscape, rather than Yoocheon-ri (2.051). 4) In the case of shape index, road (13.09) had more complex and irregular shape than either agricultural irrigation canal (3.35) or artificial forest (2.46) in Sanduk-ri. Road (6.52) was also the most irregular biotope shape, followed by river (5.70) and agricultural irrigation canal (4.78) in Yoocheon-ri. 5) Mean Nearest-neighbour Distance (MND) was smallest in wet paddy and dry paddy biotope types in the two study area, suggesting that these biotope types were concentrated within these study areas. From the result, this research suggested information to protect and improve biotopes of eco-villages in the landscape ecological terms. To achieve this improvement plan, there should be strong support by ministry of environment and local governments.

A cDNA of coagulation Factor IX gene has been screened from the $\lambda$gt11 human fetal liver cDNA library, and used to construct a 2.8-kb full length cDNA after recombining with the N-terminal fragment from pTZ-FIX. Human genomic DNA was isolated, digested with the restriction endonucleases, TaqI, EcoRI, and HindIII, and Southern hybridization was performed using the full length factor IX cDNA as a probe. The hybridized bands generated by the restriction endonucleases were the followings: TaqI, 0.3, 1.0, 1.6, 1.8, 2.7, 3.7, and 5.3 kb bands; EcoRI, 1.8, 4.8, 4.9, 5.5, 6.8, and 12.6 kb bands; HindIII, 4.1, 4.4, 5.2, 5.8, 7.6, and 12.5 kb bands. When the Southern bands were physically mapped along the genome, about 50-kb continuous region harboring almost all of the genomic region of Factor Ⅸ gene was covered. These results suggest a possibility of using an exonal cDNA probe to diagnose abnormalities including large deletions, insertions, and rearrangements along the genome, if there is any.

최근 전자상거래 보안을 위해 공인 인증서를 사용하는 공개키 기반구조(PKI) 환경이 널리 확대되고 있다. 이에 따라 인증서의 정당성을 확인하기 위한 공개키 인증서의 실시간 검증에 대한 연구가 활발히 진행되고 있지만 이러한 연구에서는 서비스를 제공하는 서버와 클라이언트 간의 메시지 형식만을 기술하고 실제적으로 서비스를 제공하기 위한 정보 획득에 관한 모델 제시가 나타나 있지 않으며, 현재성있는 인증서 상태를 제공하기 위한 방법이 제시되고 있지 않다. 본 논문에서는 공개키 기반구조에서 사용하고자 하는 인증서의 현재 상태 정보를 제공하며 인증서의 유효성을 실시간으로 제공할 수 있는 실시간 인증서 검증 시스템을 구축하는데 유용한 모델을 제시한다.
