최근 도시에서 생산되는 수많은 디지털 데이터를 저장, 운용, 분석하기 위한 3차원 도시 공간정보 인프라에 대한 수요가 증가하고 있다. CityGML은 OGC (Open Geospatial Consortium)의 3차원 공간정보 데이터 표준으로서 도시 데이터의 교환 및 속성 표현에 강점을 가지고 있으며, 최근 싱가폴, 뉴욕 등 몇몇 도시를 중심으로 CityGML 형식의 3차원 도시공간 데이터를 구축한 사례가 등장하였다. 그러나 현재 CityGML 데이터의 제작 및 편집을 위한 생태계는 sketchup이나 3d max 등 3차원 데이터 구축에 활용되고 있는 상용프로그램과 비교할 때 완성도가 부족하여 대규모로 CityGML 데이터를 구축하는 데 한계가 있다. 따라서 본 연구에서는 항공 LiDAR (Light Detection and Ranging) 나 RGB (Red Green Blue) 카메라를 이용하여 신속하고 자동으로 제작되는 3D mesh 데이터 및 2차원 폴리곤을 활용하여 3차원 공간정보 표준인 CityGML 데이터를 구축하는 방법을 제시하였다. 데이터 구축과정에서는 각 객체가 다양한 CityGML LoD (Level of Detail)로 표현될 수 있도록 원본 3D mesh 데이터를 변형하였고 공간정보로서 활용도를 높이기 위해 2차원 공간정보 데이터로부터 추출한 속성정보를 보조적으로 활용하였다. 본 연구에서 제작한 도시 3D 객체는 CityGML 건물, 교량, 도시시설물, 도로, 터널이며 객체별 데이터 변환, 속성 구축 방법을 제시하고 가시화 및 유효성 검정을 진행하였다.

In this study, noise analyses were performed toward ten school and one library-building adjacent to road. In particular, noise levels measured in the case-study city were compared to those from environmental noise standard as well as to encouraged noise level. In the analyses, the following conclusions are emphasized in order to make comfortable educational learning environment. 1) When windows were open, the measured noise level of 9 schools exceeded the encouraged noise level. In order to mitigate the exceeded level, it is necessary to plant trees or lawn and install soundproofing wall. 2) When windows were closed, the measured noise level of the most schools showed lower than that of encouraged level. For sound insulation, installing both double window and casement window are required. 3) Schoolhouse's vertical arrangement from the road in order to minimize the expected noise effect, and provision of green space by which visual hiding as well as psychological comfort are presumably achieved.

The present age demands a change in attitude based on a differentiated life value from city. It will provide to a fundamental solution for the gap of living level in the farming and fishing communities and recreate distinguishing comfortable communities. The purpose of this study was to deduct the formation characteristics of the townscape of Korean slow city according to analyze resources and structure of landscape. Planning of slow city's townscape is a process of imagification of filtrate unique meaning. The glob share synchronic unique values by slow city's network. Therefore instead of putting emphasis on promoting tourist business for short-term revenue, it will be under control to raise the standard of living and to be not forfeited and diluted the rights for sustainable slow city's status. Participation of resident needs in this process. Accordingly it need a strategy of landscape formation design and a interdepartmental practice system for a continuous slow city's image by renewal of disharmonious townscape in the built-up area.

Up to now, a lot of houses, roads and other urban facilities have been damaged by natural disasters such as flash floods and landslides. It is reported that the size and frequency of disasters are growing greatly due to global warming. In order to mitigate such disaster, flood forecasting and alerting systems have been developed for the Han river, Geum river, Nak-dong river and Young-san river. These systems, however, do not help small municipal departments cope with the threat of flood. In this study, a real-time urban flood forecasting service (U-FFS) is developed for ubiquitous computing city which includes small river basins. A test bed is deployed at Tan-cheon in Gyeonggido to verify U-FFS. Wireless sensors such as rainfall gauge and water lever gauge are installed to develop hydrologic forecasting model and CCTV camera systems are also incorporated to capture high definition images of river basins. U-FFS is based on the ANFIS (Adaptive Neuro-Fuzzy Inference System) that is data-driven model and is characterized by its accuracy and adaptability. It is found that U-FFS can forecast the water level of outlet of river basin and provide real-time data through internet during heavy rain. It is revealed that U-FFS can predict the water level of 30 minutes and 1 hour later very accurately. Unlike other hydrologic forecasting model, this newly developed U-FFS has advantages such as its applicability and feasibility. Furthermore, it is expected that U-FFS presented in this study can be applied to ubiquitous computing city (U-City) and/or other cities which have suffered from flood damage for a long time.

The Unite d'Habitation at Marseilles was an experimental project that Le Corbusier had been waiting for since 1920s in order to explore his ideals and visions in mass housing and city planning. As a leader of the first generation members in CIAM, Le Corbusier tried to give a new form and an order to the Unite d'Habitation at Marseilles in both building design and city planning level. The purpose of this research is to investigate the design characteristics of the Unite d'Habitation at Marseilles in three different levels of built environment with a particular emphasis on the process through which an original form is derived from its contextual settings. In the level of city planning, Le Corbusier aimed to reshape traditional low-rise urban housing by deploying several Unites spaciously. Le Corbusier believed that the spacious deployment of Unites would bring us both the functional economy in the city and the natural amenity in the suburbs. As Unite d'Habitation would be called frequently as vertical garden city, the influence of suburban garden city on Unite d'Habitation is apparent. In the building level, the binomial harmony of individual-collectivity was pursued by providing three different public floors and by combining 23 different family unit types in the Unite d'Habitation at Marseilles. In order to visualize the concept of object-type, family units were prefabricated and inserted into the structural frame of the Unite d'Habitation at Marseilles. Two family units are combined to make a three-story section with street corridor in the middle. This three-story section unit is very original as it has access corridor every third floor and each unit could have considerable depth with the help of the living space of two story height. In consideration of formal and plan similarity as well as contextual edivdence, it is concluded that the three-story section of the Unite d'Habitation is derived more from Narkomfin Apartments than from the monastery at Ema or Immuble Villas.

Citizen participation or resident participation is perceived as an effective way to correspond to the diverse urban problems, especially in the area of residential environment improvement projects and community activities. As the leading city of the Honam region and a core middle city leading the development of the southwestern region, Gwangju city is planning and under-developing new Housing Complexes and Urban Renewal Projects. The purpose of this study is to identify the perception of Gwangju citizens on resident participation in community activities to suggest diverse strategies for improving quality of citizen's life and making better living environment. For the research purpose, 1,380 questionnaires were distributed to the Gwangju citizens who live in 5 autonomous districts -Dong-gu, Seo-gu, Nam-gu, Buk-gu, and Gwangsan-gu- and 601 were used in data analysis. Although citizens in Dong-gu showed the lowest settlement consciousness, they required the highest level of need for resident self-help activities. Contrastingly, Seo-gu showed the highest level of settlement consciousness and the lowest need for resident self-help activities. Based on the results, high quality community facility should be provided to promote residential satisfaction and consciousness of residential participation and self-help activity must be improved. And also, diverse strategies for resident participation including development of resident education programs and search for regional resources should be covered in further research.
