Reckless development policy, which has continued during the past several decades, caused landscape damage. In order to solve this problem, it is very urgent to conserve the habitat and to establish systematic database. Recently, various researches related to landscape damage have been conducted actively and the necessity of landscape ecological planning based on the biotop mapping has been issued as one of the solutions. Therefore, the purpose of this study is to select the study area, which is located in Guji-meon, Dalseong-gun, Daegu and will be formed into Daegu Science Park, and then to develop and apply the landscape ecological planning model based on biotop mapping in district unit. The results are as follows. Fist of all, according to the results of biotop classification with field survey and literature review, total 13 biotop and total 63 biotop types were classified. According to the first evaluation with B-VAT, total 19 biotop types were classified I grade including natural river with abundant plants(BA) and so on. While V grade, which has lowest value, was classified 16 biotop types including vegetable garden adjacent to river(BC). Also the second evaluation, we analyzed total 30 areas such as 1a, 1b grades, which had special meaning for the conservation of species and biotop. Next, 2a, 2b, 2c grades were analyzed total 82 areas. Secondly, in the compliance with Ecological landscape planning, we divided landscape planning model into two parts such as setting of improvement goal and detailed implement plan. For instance, setting of improvement goal, we classified 9 parts such as conservation region and parts of detailed implement plan, we classified total 28 planning indicators with 4 view such as the region which should be special protected from nature and landscape. Lastly, with the developed landscape model we applied to research areas, made maps, and differentiate proposals in each region. Specially, the final master plan was made to help understand the contents of detailed landscape planning. This study will be a useful data, which can solve the landscape damage problem systematically and control it landscape-friendly with biotop classification, evaluation, landscape ecological planning model, and application method which we developed.

Distribution planning requires comprehensive knowledge about not only distribution but also transmission/subtransmission system expansion plan. At the same time, distribution planning is very time consuming and a series of routine job which involves a lot of experience and efforts of planning engineers. Since the quality of distribution planning depends upon the ability of planning engineers, the economy of investment should be taken into consideration. The object of this study is to establish a computerized distribution planning system which helps distribution engineers finding a new system expansion plan. It provides the engineers with at optimal system expansion plan which satisfies the condition of both reliability and economy.

The purpose of this study is to clarify the actual conditions of the plan composition of expressway service facilities. This study investigated the characteristics of both indoor space and outdoor space of 15 service facilities, and then analyzed attributes of users by the plan type along with their perception on the facility usage. The results of this study are summarized as follows; 1) When analyzing the attributes of expressway service facilities users, 36% respondents said that they used the expressway service facilities just to rest. The average distance of using the service plaza was found to be approximately 67km. 2) In terms of the indoor space of the expressway service facilities, as basic patterns, B(R+C+T)-type(53%), A(C+R+T)-type(40%), C(C+T+R)-type(7%) were found in order, all the service facilities need to expand them.

Sesame oil is a simple pressed oil as unrefined oil. During manufacturing process of roasting-expression, benzo(a)pyrene[B(a)P] formed as a strong carcinogenic substance is cause a social problem. In manufacturing process of sesame oil, it had following the forming pathway of benzo(a)pyrene[B(a)P] as well as minimizing plan of B(a)P formation. Suitable roasting condition by roaster was during 15~20min at $220^{\circ}C$, B(a)P content in sesame oil was $1.35{\sim}1.57{\mu}g/kg$. Between roasting temperature and/or roastingtime and forming amount of B(a)P was showed a linear correlation. As a point of view the turbidity and yield of final product, roasting process of the more regular level was required.

전통기업의 e-Transformation을 위래서 온라인/오프라인 기업들은 새로운 비즈니스 모델 수립을 모색하고 있으며, 정부는 업종별 B2B 전자상거래 사업을 추진하는 등 부단한 노력을 하고 있다. 그러나 이러한 노력에도 불구하고, 세계적으로 B2B Marketplace들의 경영 부진 및 저조한 시장참여도 현상이 매우 심각한 것으로 나타나고 있다. 이에 국내 유통산업의 B2B현황 및 문제점을 살펴보고, 선진국의 유통산업 동향을 고려하여 국내 유통산업의 바람직한 e-Marketplace 구현 방안을 제시하고자 한다. 본 논문에서는 전자상거래 활용 및 대응을 위한 e-Marketplace의 역할 및 의의를 살펴보고, 선진유통업계의 전략적 제휴를 통한 e-Marketplace 구축 사례 분석 및 국내 유통산업 entities의 needs분석을 바탕으로 유통산업에서의 e-Marketplace 구현방안을 수립하였다. 특별히 본 논문에서는 유통산업 전자상거래 ISP에서 검토된 실질적 방안을 제시하는데 중점을 두었다.

인천국제공항과 김포국제공항을 포함하는 서울 접근 관제 구역은 하루 1,000여 대의 항공기가 운용되어 혼잡할 뿐만 아니라 북쪽으로 공역이 제한되어있기 때문에, 항공기 간의 적절한 분리 유지를 통한 안전관리가 까다롭고 관제사의 업무 부하가 높은 편이다. 본 연구에서는 최근 3년간의 ADS-B (automatic dependent surveillance-broadcast) 항적 데이터를 기반으로, 관제사의 벡터링이 추가되지 않은 원래 비행계획 상의 항로와 절차를 예측하고, 이를 이용하여 서울 접근 관제 구역 내 항공기 운용의 구조적인 안전도를 분석하였다. 안전 지표로서는 대형 무인항공기의 탐지 및 회피 시스템에 적용하기 위해 개발된 DWC (detect and avoid well clear) 지표가 사용되었으며, 이를 통하여 가장 위험도가 높은 지역들을 판별하였다. 활주로 방향에 무관하게 인천국제공항의 서쪽 지역을 사용하는 이/착륙 절차 주변이 가장 위험도가 높게 나타났다. 이외에 도착 절차들의 합류 지점과 출/도착 절차들의 교차 지점이 상대적으로 위험도가 높게 나타났다.

A study on the traditional houses of North Korea(I) have been published in 1996. This paper is written to supplement the preceding paper. This paper aims at collecting new data of traditional house in North Korea. But still being prohibited for the researchers of South Korea to approach to the field, I had to depend on the memories and experiences of the immigrants from North Korea who are now living in Kangwon and Incheon Province. Through the questionnaire and drawings, they described vivid memory of their old houses. I was able to add new data of 70 cases, which are significant and valuable as much as those of the real field are. Those data, including the exisiting data, are enough for me to analize statstically the regional charateristics, the differnces among economical classes, and the periodical change. It opens the way for verfying the existing theory. Regional charateristics of house in North Korea can be described as followings: a. Hamkyong-do ; Concentrating spaces into one building, Double-fold type plan, Including 'cheongju-kan' space, Weak fences b. Pyongan-do ; Concentrating spaces into two buildings, 二 shape buildings , Single-fold type plan, Strong fence c. Pyongannam-do to Myolak mountains; Concentraing spaces into two buildings, ㄱ, ㄷ shape buildings, Single-fold type plan, Strong fence d. Southern area of Myolak mountains; Concentrating spaces into one building ㅁ shape building, Single-fold type plan with wooden floor space
