A lot of city have different characteristics in their location, space and environment each other. These characters are the factors showing inherent placeness of each space, and those factors should be reflected sufficiently in urban planning and development. Nonetheless, there are many parts that are not actually reflected in the plan, and this creates a space of unexpected arming. Especially, port area in a port city has strong characteristics of culture, history, geography and environment of the city concerned so it must make more creative and unique space. Therefore, it is considered that not only the physical factors but also the social factors should be actively reflected to highlight the place character of the port space. In this paper we are to construct the factors forming the placeness of port space based on the Form Based Codes rising as a flexible urban planning method in order to avoid rigidity of existing use district zoning system, and establish the placeness character of each port area.

웹 환경에서 OpenGIS(Open Geodata Interoperability Specification)의 상호 운용성을 검증하기 위한 웹 매핑 테스트베드는 기존의 웹 브라우저를 사용하여 다양한 데이터 서버에 저장된 지리 정보를 발견, 접근하는 것을 목적으로 한다. 이 환경에서 클라이언트는 맵 서버가 XML(Extensible Markup Language)로 부호화한 지리 정보를 전송 받아 화면에 출력할 뿐만 아니라, 이러한 XML 지리 정보에 대해 공간 분석을 수행해야 한다. W3C(World Wide Web Consortium)의 DOM(Document Object Model)은 XML 분석을 위해 표준화된 인터페이스를 제시하고 있으나 공간 분석을 위한 인터페이스는 지원하지 않는다. 본 논문은 웹 환경에서 다양한 데이터 서버로부터 전송된 XML 지리 정보의 공간 분석 방법을 제시한다. 먼저 공간 분석을 위해 국제 표준화 기구에서 제시된 공간 연산자들을 분류한다. 그리고 DOM에 공간 연산을 지원하는 공간 연산 인터페이스를 추가한 GDOM을 제시한다. 마지막으로 클라이언트에서 GDOM을 이용하여 공간 분석을 수행하는 경우에 공간 연산자 수행 방법을 기술한다.

Environment-friendly design becomes one of the main issues of the contemporary design. It has been developed with the advent of the organic view of the wend. It started as the environment-protective orientation and then enlarged its boundary including the designs which aims to revive the organic relationship between human and nature. Recent design approach in environment design emphasizes to be 'synchronized with the nature' and its basic attitude is the revival of the right relationship between man and nature. It also can be described as the design for Green Amenity. This paper researches on the concepts, types and the roles of the environmentally-friendly design. There are two basic concepts : one is environment-protective attitude and the other is the attitude which emphasizes the function of Green Amenity. This paper focuses on the latter approach. Through the analysis of the necessity and the function of the environmentally-friendly design, it aims to prove the fact that valuable human life need the design which connects human life aye with natural environment.

The purpose of this study was to establish a conceptual management spectrum framework for integrated management of Baekdudaegan area. The conceptual model was developed through a literature survey that includes the concepts from existing relevant systems and other expert sources In conceptual Baekdudaegan management spectrum framework presented here, three different classes (preservation, buffer, and multiple-use) that specify potential management objectives for area functions were classified in order to pursue management flexibility Three primary management classes should be identified by evaluating Indicators of ecological, physical, and social.cultural environments. An application of the framework requires an explicit selection of indicators and their evaluation. For establishing reliability of the framework, it will be desirable to test it empirically in Baedudaegan areas in the future. In addition, systematic case study for selecting appropriate indicators and identifying evaluation standards must be done.

In order to expand the qualitative aspects of public facility, this study used SNS data to derive user-oriented preference factors for public facilities and then were quantified in terms of supply side and demand side. To derive preference factor, LDA, one of topic modeling, was used and attraction index was calculated for each facility. In addition we analyzed spatial accessibility to measure the degree of service experience of users by using 2SFCA model. The study area covered public libraries of Seoul, Korea. As a result of study, five topics were extracted as preference factors for the public library: Circumstance, Scale of facility, Cultural program, Parenting, Books and materials. In particular topic of circumstance and parenting were newly derived preference factors unknown in previous studies. As a result of calculating attraction index for each library, the index of Songpa Library, Jungdok Library, and Namsan Library was high. Songpa library has received good evaluation in parenting factor, and Jungdok & Namsan library in circumstance factor. The accessibility of each region seems to better in center of Seoul where public libraries are crowded, but shrinking toward the outskirts. We expect that the proposed method will contribute to user-oriented public facility evaluation and policy decision making.

This study aims to empirically identify the effect of spatial accessibility, based on travel, on housing prices in the Korean capital region. More specifically, it has two research purposes: First, investigating the effect of comprehensive spatial accessibility, based on road network and actual trips from origin to destination, on average apartment price (Korean Won per square meter) at the level of Eup, Myeon and Dong; Second, identifying better accessibility index between Hansen's and Kalogirou and Foley's ones. The former represents a road-based travel time decay function with destination trips, while the latter is a function with origin trips as well as destination ones. The study employs spatial economic models considering spatial auto-correlative relationship as an appropriate methodology with such control independent indicators as population density, road density, educational environment and distances from CBDs. Analysis results demonstrate that spatial accessibility, based on road network and actual trips from origin to destination, has a statistically significant impacts on housing price in the region. Our empirical evidence proves that the Hansen index is more appropriate than the other in estimating housing price impacts.

Recently, the gated community has been increasing due to various reasons such as demand for differentiated areas and security, but various problems have been raised, including regional conflicts, traffic restrictions and disconnection of surrounding areas. Therefore, this study empirically considered what kind of spatial effect the gated community has on the surrounding area by analyzing the vitality using floating population big data and analyzing pedestrian accessibility using network analysis and social network analysis. As a result, it was found that the overall vitality in the study area was greatly affected by the land use and the building use. However, focusing on apartment complexes, even in the same land use, when the form of the complex is open to the outside, there is a lot of floating population, so the vitality is high. In terms of accessibility, assuming that the gated community is open, it was found that as the physical connectivity improved, there were more roads for pedestrians to choose from, and the accessibility improved as traffic and exchanges occurred in the disconnected space. The value of improving property rights and residential environment is also precious, but it is necessary to review how to reflect the improvement of local permeability in enhancing the publicness of cities and the value and direction of communities that can coexist with the region.
