The purpose of this study was to analyze biotope types of urban land-use patterns. Forest areas were considered according to vegetation type and potential for succession. Urban ecosystem structure was analyzed according to land use, land coverage, vegetation structure (actual vegetation, diameter at breast height, layer structure, and revetment). As a results of the classification, the biotopes were divided into 71 types according to the urban ecosystem structure. In the case of the Hanam province, the biotopes were divided into 51 types: 26 forest types; 5 swampy and grass land types; 3 farm land types; 3 types of planted land, and 8 types of urbanization.

The present study has been conflicted to verify the applicability of tire powder and food waste compost as biofilter materials to degrade volatile organic compounds. Batch and column tests were performed to determine the optimum ratio of tire powder to compost and the appropriate mixing type of two materials for removal of the selected VOCs, i.e., benzene, ethylbenzene, PCE, and TCE. According to batch tests, tire powder and compost mixture had faster removal rate than the compost. The biofilter column filled with tire powder and compost showed better VOC removal efficiency than that filled with only tire powder. In this study, the best removal rate was observed in the sandwich type column test of which the tire : compost weight ratio was 1:2

As the skyscraper matures as a building type, its role in actively connecting to, and reinforcing, major threads of urban fabric becomes increasingly more important. The creation of public spaces inside of and adjacent to tall buildings allows for significant additions to the public realm, facilitating better connections between varied uses, providing needed access to critical transportation functions. In this more integrated version of the tall building type, the density afforded by a vertical structure is complemented by strategically devised porosity of plan and section. This paper examines three major tower projects which exemplify a progressive approach to permeable design: the recently completed Jingan Kerry Centre in Shanghai, the Lotte Supertower in Seoul, now half completed, and the One Vanderbilt tower being proposed next to Grand Central Terminal in New York City. These projects suggest possibilities for innovative approaches to private development strategies, public planning processes, and architectural design.

The park in city, is more than just ecological function, contributes emotional refinement and psychological stability to citizens, and give satisfaction of social and recreational activities to the citizens. And it is the place of leisure and the place to raise up the quality of urban environment. Especially, the neighborhood park among urban parks occupies the most important position as a leisure space for local resident, but it can not perform its purpose and function as a leisure space, due to its too formal and insufficient facilities. This study, approaching from point of physical method, intends to make types through classifying each parks by built-type and installed facilities which affect human-beings, approaching from point of human-beings, intends to make the using-type analysis of park-users, and the questionnaire.By grasping of their requirements regarding to the characters and facilities what they want, willing to present the fundamental data for effective utility-activating method of small-scaled neighborhood park.

The purpose of this study is to examine the transforming characteristics of village at the urban fringe, which are influenced by the urbanization. Three areas in the urban fringe are selected for the case study. The changed conditions in the spatial structure of those areas are reviewed through following factors : street system, an entrance of village, a boundary of village, community facility, development density, housing type, building use. The transforming characteristics are analyzed as a result of the research. In result, the community facility, development density, housing type and building use are changed largly in the transforming characteristics.

The purpose of this study was to systematize space composition characteristics of urban traditional housing in Bukchon area. Out of 924 existing houses, 106 houses were selected and analyzed based on availability of documents and its function as pure residential living. According to which major rooms were changed, six categorizes were delineated as follows : unchanged type, type with changed Anbang, type with changed Gunnunbang, type with changed Aratbang, type with changed Daichung and totally changed type. Characteristics of each type were systematically analyzed and described. The results showed how traditional culture and contemporary lifestyle coexisted and were integrated.

옛날에는 거대한 바위를 제거하기 위해서는 다이나마이트 등의 폭약을 사용하여 폭파개념의 발파를 해왔다. 그러나 도심지에서 지하철굴착, 건물기초굴착, 택지조성 등을 위해서는 폭파개념의 굴착은 곤란하다. 건설교통부 암발파설계 및 시험발파 잠정지침(안)에서는 0.3cm/sec(센티세크)를 진동안전기준치로 하였을 때 $25\~120m$ 이격거리에서는 TYPE I의 암파쇄굴착공법에서 TYPE IV의 진동제어중규모 발파공법을 권장하고 있다. 본 논문은 25m이내 지역의 최근접 암파쇄굴착공법(TYPE I)적용 최적공법인 나노프라즈마 공법을 소개하고자 한다. 나노프라즈마 공법을 적용하여 도심지 바위를 파쇄할 때 15m거리에서 기존의 미진동발파공법의 절반 진동수준인 0.1cm/sec가 예상되는 획기적인 공법이다.

강원도내 14개 시군을 3개 지역(도농통합형 지역, 도시형 지역, 농촌해안형 지역)으로 나누고 지역에 거주하는 지역자율방재단을 표본집단으로 하여 설문조사한 결과, 도농통합형 지역과 도시형 지역이 농촌해안형 지역보다 재해위험인지능력, 피난유도능력, 자주피난 대비정도, 방재체제 정비정도, 감시경계능력, 정보전달능력 등 모든 분야에서 낮은 것으로 분석되었다. 특히 정보전달능력은 3개 지역 모두 높게 나타났으나 자주피난 대비정도는 매우 낮은 것으로 분석되었는데 이는 정보전달능력의 경우 지방정부의 예 경보시스템 증설과 신규 설치로 인하여 재난정보를 신속히 제공할 수 있는 기반이 구축되었지만 자주피난 대비 정도는 주민 스스로가 재해 상황을 정확히 파악할 수 있도록 지속적인 재난대비 교육과 홍보를 실시하고 더불어 사전에 안전한 대피장소 확보방안 등을 모색하여야 할 것이다.

This study deals with the traffic accident of truck at circular intersection. The purpose of this study is to develop the truck accident models based on type of accident and conflict. In pursuing the above, the study gives particular attentions to selecting the appropriate models among Poisson and Negative binomial models using statistical program LIMDEP 8.0. The traffic accident data from 2007 to 2014 are collected from TAAS data set of Road Traffic Authority. Such the dependent variable as number of truck accidents and the 24 independent variables as geometry, traffic volume and others are used. The main results are as follows. First, 5 Poisson models (${\rho}^2$ of 0.164~0.351) which are all statistically significant are selected. Second, the common variable based on type of accident and conflict is analyzed to be truck apron width. The specific variables are, however, evaluated to splitter island, area of splitter island, speed limit sign, truck apron, number approach road, circular intersection sign, speed hump and traffic volume. Finally, widening the truck apron width and improving the above specific variables are analyzed to be important for truck accident reduction at circular intersections.
