토지이용의 합리화를 위하여 도입된 토지이용규제는 사회경제적인 발전과 함께 복잡다기화 되면서 국민경제생활에 불편을 초래한다는 이유로 최근 규제 완화로 패러다임이 변화하고 있다. 이에 본 연구에서는 CA 모델을 이용하여 시뮬레이션 함으로써 부산권 도시성장의 잠재지역을 도출하고, 토지이용 규제지역과 함께 공간적 특성을 분석하였다. 분석을 통해 토지이용규제 제도가 실제로 도시성장을 억제하고 토지이용의 효율화를 도모하고 있는지, 또는 국민생활에 불편을 초래할 수 있는 다른 요인이 있는지를 검토하였다. 분석결과 도시외부의 개발압력이 높은 지역에 존재하는 개발제한구역은 토지이용규제라는 역할을 수행하고 있었지만, 많은 지역에서 토지이용에 대한 다중규제가 존재하는 것으로 나타났다. 따라서 순기능을 하고 있는 토지이용규제는 최대한 유지하면서, 도시성장 잠재력이 높은 지역에 존재하는 다중규제를 재고하는 등 다양한 접근과 검토가 필요할 것으로 사료된다.

The purpose of this research is to evaluate the biotope value in a metropolitan area after constructing the biotope evaluation model to develop biotope networking in the light of ecological landscape planning. In addition this study is to provide a basic frame of constructing the biotope networking system in the future with the evaluation results. The scope of this research is limited to high density residential area including some part of the forest adjacent to urban boundary. The results of the classified biotope in the research area have been turned out to be 24 patterns. According to the result of estimated nature value having the forth grade, three were forests combined with urban natural parks, schools near forests, and grasslands. There is a little place having first grade. We an deduce this fact that we have surveyed biotopes, having the minimum nature value and wider than children's park. As for the result of evaluated the structure, there were the forests of Seong-Dong, Meaho-Dong, and Kumho river, which is the forth grade. As for the evaluation of connection-function, the followings area were evaluated as the third grade-linear biotopes having highly valued and sustainable similarity - Seoul-Pusan Railroad, Dong-Daegu St., Kumho river, river basins. Bum대 park and a botanic park near Suesung lake, As for the evaluated the buffer-function, higly valued production biotopes, existing at a transition belt between he residential density areas, are Sawol-Dong, Meaho-Dong and Kumho river. When each of the indexes was evaluated, the core of the biotop contained most of natural biotopes. Large artificial biotopes were evaluated as an important biotopes, while small artificial biotopes were classified as a dot biotope. The future research on the concrete biotope networking construction, based upon performed evaluation in this research, should be conducted.

Buildings undergo changes by various factors according as pass at time. Due to that social requests and issues form one common sense of value and this would influence the architect's design intention. In fact, the form and function of buildings have coped with transition of the common sense of value by each times. Hospital architecture is also changed in function, scale and technology since, Kwanghyewon which was the first western style hospital in Korea was established in 1885. It is changing that the social needs for hospital which was a basic function of healing to laying emphasis on the function of precaution. According to this, the change of hospital spaces means that it can promote healing environment which is expanded from the modern concept of isolation, accommodation and urban sanitation. These changed concepts were adopted limited areas in hospitals at first however, nowadays they are expanding to other areas. So, this is caused to make the image of the hospital. From this point of view, Entry space is an example to show the changes. This study is intended to determine the overall space structure of entry area and to classify and analyze the difference.

과거 우리는 경제성장을 위해 집약적으로 도시를 개발해 왔고 이러한 개발정책이 자연생태계에 부정적인 영향을 미쳐왔던 것은 간과할 수 없는 사실이다. 본 연구에서는 이러한 부정적인 영향의 평가를 위해 대구광역도시권을 대상으로 GIS 기법과 경관지수를 이용하여 도시성장에 따른 토지이용과 경관을 구성하는 요소들 상호간의 시 공간적 패턴을 분석하였다. 분석결과 주변지역으로 도시기능의 전이에 따라 도시는 $193.4km^2$가 확산되었으며, 산림은 다른 토지피복패턴으로 $455.6km^2$가 잠식된 것으로 나타났다. 이러한 변화의 과정에서 가장 큰 비중을 차지한 것은 상대적으로 개발여건이 양호한 농경지의 변화임을 알 수 있었다. 또한 산림은 구조적으로 파편화되고 형태는 복잡해졌을 뿐만 아니라 인접패치의 패턴도 다양해진 것으로 나타났다. 이러한 변화는 산림에 대한 외부간섭 또한 증대시켰을 것으로 생각되며, 아울러 생물종의 서식처가 되는 핵심지역을 감소시켜, 그 건전성을 저하시킬 가능성이 있는 것으로 판단된다. 이러한 연구결과는 향후 더욱 광역화되어지는 도시의 개발이 주위 환경구조에 미치는 영향과 상호관계성을 평가하고, 경관생태학적 원리를 고려한 광역도시계획수립의 기초자료로 활용 가능할 것이다.

최근 산업도시 성장 이후 탈산업화 시대에 전개되는 새로운 도시화에 대한 논의가 포스트모던 도시, 소비도시 등으로 다양하게 전개된다. 도시화의 단계적 접근에서는 인구 변화와 이동에 기초하여 거대도시는 도시화의 후기 단계인 재도시화를 경험하고 있으며, 이러한 도시화 단계는 시차를 두고 점진적으로 하위 규모 도시에서 나타날 것으로 추정된다. 그러나 산업 재구조화는 인구 규모만으로는 포착되지 않는 새로운 도시화 특성을 유발할 것으로, 본 연구는 한국 대도시의 도시화 특성을 이동, 통근 인구 그리고 이들의 지리적, 사회적 특성에 기초하여 검토하였다. 대도시별 도시화 경험은 다르게 나타나는데, 서울은 단계적 도시화 과정을 거치지만, 다른 대도시들은 산업도시와 탈산업도시로의 전이에서 다양한 모습을 드러낸다. 특히, 지방 대도시의 경우 산업 기반의 교외화가 이루어졌으나 중심 도시의 편리한 주거, 생활 환경으로 중심 도시에 거주하며 주변으로 역통근하는 인구가 늘고 중장년층의 경제활동 가구가 대도시로 유입되며 주거 기능이 새로운 도시의 역할로 확대되는데, 이는 한국 대도시의 새로운 도시화 특성이라 하겠다.

Targeting a rooftop biotope created in urban area, this study aims at verifying a creation technique reflecting an urban biosphere reserve concept as well as its function as the habitats of various wild animals. To this end, a set of processes of a biosphere reserve-based basic conception and master plan, sectoral plans, construction and monitoring were applied to the rooftop of 12-story UNESCO Building in Seoul. In particular, the rooftop habitats were divided into core area, buffer zone and transition area, and habitats and facilities suitable to the characteristics of each space were planned. By aligning a plantation planning map with environmental conditions such as topography and water, creation of diverse habitats was enabled. As a result, a set of various habitats including wetlands, wild grassland, shrubs, forest trees and vegetable fields was created at the site. Species living in these habitats included 148 plant species, 62 insect species, 2 amphibian species, 3 fishery species and 3 bird species. The rooftop eco-park of UNESCO Building, which was created one year ago, is assessed as an important space for conservation of biodiversity as well as a place where a biosphere reserve concept was well applied. Meanwhile, for this rooftop biotope to be a pioneer of urban biosphere reserve-based types, a number of principles & methodologies suggested in this study need to be applied, In a perspective of landscape ecology, maintenance efforts should be linked with green areas in neighboring areas, which are the sources of species, In addition, considering that the rooftop biotope is a restored ecosystem, theories and approaches from restoration ecology should be applied. On-going monitoring on environmental changes is also required as the site is located in the urban center, Ultimately, rooftop biotopes including the case study area should contribute in promoting the socio-economic, cultural, and spiritual sustainability as well as environmental sustainability of a city.

The performance of a cognitive radio network (CRN) solely depends on how precisely the secondary users can sense the presence or absence of primary users. The incorporation of a spatial false alarm makes deriving the probability of a correct decision a cumbersome task. Previous literature performed this task for the case of a received signal under a Normal probability density function case. In this paper we enhance the previous work, including the impact of carrier frequency, the gain of antennas on both sides, and antenna heights so as to observe the robustness against noise and interference and to make the correct decision of detection. Three small scale fading channels: Rayleigh, Normal, and Weibull were considered to get the real scenario of a CRN in an urban area. The incorporation of a maximal-ratio combining and selection combing with a variation of the number of received antennas have also been studied in order to achieve the correct decision of spectral sensing, so as to serve the cognitive users. Finally, we applied the above concept to a traffic model of the CRN, which we based on a two-dimensional state transition chain.

오늘날 장강삼각주지구(長江三角洲地區)(약칭: 장삼각(長江三))라는 명칭은 행정구역상으로 상해시(上海市)(1개 성급(省級) 성시(城市))를 비롯한 16개 성시(城市)(3개 부성급(副省級) 성시(城市))와 12개 地級(지급) 城市(성시)를 가리킨다. 개혁 개방(1978) 이후, 특히 포동신구(浦東新區)의 개발 개방(1992) 이후, 지금까지 장강삼각주지구(長江三角洲地區)의 발전 속도는 중국에서는 물론이고 다른 국가에서도 그 유례를 찾아보기 힘들 정도로 빠른 것이다. 본 연구는 1978년부터 2006년까지 장강삼각주지구(長江三角洲地區) 공간구조(空間構造)의 현대적(現代的) 변용(變容)을 산업화(産業化), 성시화(成市化), 경제일반화(經濟一般化)라는 세가지 측면에서 분석하는 것을 목적으로 하고 있다. 이러한 분석의 결과, 산업화에 있어서 수평적이고 수직적인 공간적 분화가 지금도 진행되고 있기는 하지만 아직까지 만족할 만한 수준에는 도달하지 못하고 있다는 사실이 밝혀졌다. 시장과 기업의 활동에 대한 정부의 지나친 행정적 간섭이 서비스 산업을 비롯한 산업의 성시(城市) 간(間) 공간적 분화를 수반하는 경제일체화(經濟一體化)를 방해하고 있는 것으로 보인다. 또한 동일한 공업 업종에 대한 중복 투자와 건설로 인하여 성시(城市) 기능(機能)의 특화(特化)가 아직까지 성숙 단계에 접어들지 못한 상태에 있는 것으로 보인다. 성시(城市) 계층(階層)의 구성에 있어서 대성시(大城市)와 소성진(小城鎭)의 기능을 공간-경제적으로 중계하는 역할을 하는 중등성시(中等城市)의 숫자가 상대적으로 부족하다.

University campus has grown and developed along with history of human in connection with transition characteristics of city. In particular, reflecting the features in the times, the masterplan should explore its main roles today when international growth of university is pursued. In particular, center core and quad space, focusing on main components of campus such as main building, student union hall and main lecture facility, are the prototype of campus components and have been pursued to have importance in terms of shape and function as traditional campus space strategy. Recently, however, new strategy has been proposed to explore orders of campus utilizing the underground space focusing on main universities. Design of Hana Plaza of Korea University and Bekyangro of Yeonsei University, the targets of this study, actively explore this strategy. This study analyzed such strategies in terms of concept of space to obtain space, design trend of main universities at home and abroad, and viewpoint of integrated masterplan proposal. Conclusions from this study are as follows. First, concept of quad and center space found in the design of traditional campus is reinterpreted into new design aspects through development of underground space. Second, development of underground space is approached to overcome the limit of existing campus and to present the vision of universities 100 years ahead. Third, ever-changing complicated urban environment has been reflected in space configuration of campus and positioned as strategy to implement this as modern construction technique. Third, implementation of pedestrian-oriented campus has been pursued by reinforcing utilization of inclined topography of urban environment in Korea. This enables to obtain spaces for main activities of students and to implement the space where student support facilities are concentrated and activities are performed actively. Such features can be presented as conclusions of this study.
