Agricultural Technology Center is an education center to provide agriculturalists with information and technology related with agriculture. As domestic and international environment of agriculture and rural area is changing, functions and roles of Agricultural Technology Center are evolving according to stream of times. In 1995, a new urban and rural complex city was created for symbiotic relationship between city and rural area, As a result, user group of Agricultural Technology Center expanded to nonagriculturalists. Though the change of agricultural extension service is necessary to perform extended functions of rural area and to satisfy needs of new group of users, it is difficult to find enough studies on new functions and roles of Agricultural Technology Center to manage the service change. Therefore, this study is aimed to suggest new functions and roles of Agricultural Technology Center according to stream of times. This study were surveyed through questionnaire targeting users of Namyangju Agricultural Technology Center to compare user group awareness of Agricultural Technology Center in urban and rural complex city. According to this study result, while main purpose of agriculturalists' visiting at Agricultural Technology Center was participating in education programs related with agriculture. In contrast, nonagriculturalists usually visited the center for agricultural understanding, leisure activities, and children education, participating in field work programs. From the survey result of required functions of the center, it was revealed that nonagriculturalists expected urban agriculture, research for living improvement in rural area, adjustment education for returning farmer, and function of farming promotion, comparing agriculturalists. It is verified that this difference of user group awareness reflects the necessity that Agricultural Technology Center should change services and accept increasing use of nonagriculturalists with new functions and roles.

One of the key problems in the design of high-rise commercial complex is how to guide reasonable pedestrian distribution in commercial space. In this study, pedestrian distribution in three high-rise commercial complexes in Shanghai and Hong Kong was studied using spatial configuration analysis software Space Syntax and quantification of physical elements in commercial spaces, such as functional attractiveness, entrances, escalators, level variations and passage width. Additionally, in an attempt to integrate functions with spatial integration and spatial depth, two combination variables, the spatial coefficient of function (IF) and spatial depth coefficient of function (F/D), were proposed. The results of the correlation analysis and multiple regression analyses reflected the following: (1) Regarding the influence on pedestrian distribution, there was a synergistic and complementary relationship between function and space; (2) The comprehensive flow distribution analytic model could successfully interpret flow distribution in high-rise commercial complexes and its R Square ranged up to about 70% in the three cases; (3) The spatial coefficient of function (IF) and spatial depth coefficient (F/D) could effectively integrate functions and spatial configuration, which could help close the gap between over-emphasis on function in commercial research and the lack of consideration of function in space-syntax analysis.

이 논문은 전통적인 하천의 기능을 보다 체계적으로 재분류하여, 사회적 측면(용수공급, 관리, 교통 및 에너지원), 공간적 측면(지형형성, 수변경관, 지역구성, 경계-분리) 그리고 생태적 측면(폐수배출, 정화작용, 서식지, 기후조절) 등으로 구분하고자 한다. 이러한 재분류에 기초하여 보면, 근대화 과정에서 도시하천의 기능들 가운데 특히 용수공급 등 사회경제적 기능이 강조된 반면, 공간적 측면과 생태적 측면은 무시되었다는 점이 지적될 수 있다. 대구 및 그 주변 지역을 관류하는 금호강 역시 과거 지역사회의 내적 발전과정에 지대한 기여를 했지만, 하천의 특정 기능이 선별적으로 개발된 결과 금호강은 유지수의 부족과 더불어 오염과 퇴락으로 그 본래 기능을 상실하게 되었다. 뿐만 아니라 이로 인해 금호강에 의존하여 발달해 오던 대구 및 그 주변 도시들도 더 이상 성장하기 어렵게 되었다. 이러한 사회 환경적 위기 상황을 극복하기 위하여, 본 논문은 도시 하천이 가지는 고유한 기능들에 근거하여 지속가능성 원칙과 주요 기능별 평가 지표를 개발하고, 도시와 하천이 공생적으로 발전할 수 있는 방안들을 제시하고자 한다.

This study is focused on finding out the character of urban recreation forest and investigating facilities regulations of forest resources around urban areas to meet future recreation needs. The method of this study is to compare urban recreation forests with similar facilities like urban parks and natural recreation forests. By this way, this study not only identifies the characteristics of urban recreation forest as emerging recreational facility, but also outputs regulations that can be adapted to real environment. Urban recreation forest is defined as follows: It has forest with good natural landscape and easy access. It makes emotion rich and its function is focused on outdoor recreation nature education, and experiences for family group mainly within a day or on weekends. This study suggests that the minimal area of urban recreation forest should be over 100,000$m^2$, with a facility ratio less than 20%. Building coverage should be less than 7% when the urban recreation forest is under 300,000$m^2$, less than 5％ when 300,000∼500,000$m^2$, and less than 3％ when over 500,000$m^2$ The limits of building height is 3 stories, or under 12m. This study finds out the character, the needs of urban recreation and the criterion for project feasibility. significance of the result is supplying theoretical basement on related regulation. Based on the results, further study will establish landscape management method and legislation & application in a detailed examination.

Development restriction areas (greenbelt areas) of Korea were recognized in 1970 as a means to control urban sprawl and conserve the natural environment. Although there have been some achievements, for a long time many planners and residents have requested a redefining of the green belt due to individual property rights restrictions and urban management problems. In fact, a lot of the greenbelt area is being destroyed by urban development. Therefore, conservation of ecological spaces in the green belt is needed to maintain urban naturalness. In this regard, this study suggests efficient methods to manage the greenbelt through the adoption of a landscape ecological value assessment. The greenbelt of the Seoul Metropolitan Area (SMA) is represented as the case study because there has been mounting pressure to develop the area in Korea. In this study, the assessment of the landscape ecology in the greenbelt area focuses on landscape structure and function. The assessment consists of the following steps: First, patches were derived by NDVI analysis using landsat remote sensing data. Second, characteristics of the patches were quantified by analyzing the landscape structure, such as patch size and shape index. Lastly, the gravity model and least cost path analysis to assess connectivity were applied to evaluate the landscape function in the green belt areas. The assessment result showed that 48.45% of green belt area should be conserved to maintain ecological stability and function. Moreover, major ecological networks were identified near the large patches in the northern and southern areas. However, relative low ecological values were identified in the western part of the green belt area due to the lack of green spaces. Furthermore, some development plans in the green belt were also identified near the conservation area. Based on these results, the restoration needed areas to enhance ecological value in green belt were displayed. This study suggests efficient management of the greenbelt area, which is disappearing as a result of urban development. The area for conservation chosen in this study should be managed carefully in urban planning. Finally, the results of this study can be used in green belt polices and plans for the promotion of ecological naturalness and stability.
