The purpose of this study is finding the spatial character for autogenous space design through the violation of Nam-dae-mun market. The violation is defined as the possession of space in excess of one's property. In Nam-dae-mun market, the violation is sanctioned by usage. Through the violation, Nam-dae-mun market naturally acquires autogenous energy and pliability. According to three steps, this research proceed. 1. To investigate the limitation of modern architecture and the meaning of the violation. 2. To research the present condition of Nam-dae-mun market and the process of spatial formation. 3. To compare 'F' building in Nam-dae-mun with Sam-ik fashion building which was redeveloped.

몰입형 가상현실 시스템은 3차원 탄성파, 검층자료, 해석단면 등 다양한 지하정보를 3차원 공간에 시각화 하고 분석하는데 효과적이다. 이러한 시스템은 석유나 가스 탐사에 중요한 도구로서 사용될 수 있지만, 고가의 제작비용으로 인해 특수한 분야에만 제한적으로 사용되어 왔다. 본 논문에서는 몰입감을 극대화 시킬 수 있는 가상현실 시스템인 CAVE(Cave Automatic Virtual Environment)를 일반 PC와 프로젝터를 이용하여 적은 비용으로 구축한 사례를 제시한다.

Recently the change of family environment has influence on the configuration of the family welfare unit at the social welfare center. And so the relation of space and function required its change. The essential role of social welfare center is family welfare, domiciliary and community care, community organization, social education etc. In this sence, this study explored the condition of space planning for the family welfare at the social welfare center. For this study, it was reviewed the role and function, the service program, the degree of unit activity importance, space satisfaction, the usage characteristics. In sum, the useful data were collected, analyzed, and synthesized through case study and could be used in the guidelines as reference information for the spatial organization of the family welfare unit at the social welfare centers in small town.

The recent change of social environment has influence on the configuration of space for the community social welfare center. And so the relation of space and the service function required the change of spatial configuration. The social welfare center fills the role of family welfare, domiciliary care, community service etc. In such sense, this research explore the conditions of spatial configuration for the community welfare service unit of social welfare center in small city. For this study, it was investigated the space role and service function, the service program, the usage characteristics, the room satisfaction of social workers. In sum, the useful data were collected, analyzed, and colligated by case study. It could be used in the basic design criteria of community service unit for the social welfare center in small city.

Planning Support System (PSS), an alternative framework of computer-aided planning system combining geographic information system (GIS), urban models, and visualization tools, has been actively researched and applied in many developed countries. This paper introduces a PSS-based land use change model, What if\ulcorner PSS, by applying it to Chongju City, Korea. This model application study used the spatial database, Restricted Development Zone (RDZ), and other hypothetical land supply- and demand-related policies of Chongju City. The collaborative PSS model supported land use planning process by helping users to speedily and easily create and test policy-oriented scenarios. The study found that the fully operational PSS model was readily applicable and useful to Korean local land use planning. The paper discusses the conceptual model framework, data requirement, application process, model output, and practical usage. This study would be considered as a prototypical approach of PSS-based land use plan making for Korean cities.

Classification is considered as one of the processes of extracting attributes from satellite imagery and is one of the usual functions in the commercial satellite image processing software. Accuracy of classification plays a key role in deciding the usage of its results. Many tremendous efforts far the higher accuracy have been done in such fields; training area selection, classification algorithm. Our research is one of these effort in different manners. In this research, we conduct classification using multiple satellite image data and evidential approach. We statistically consider the posterior probabilities and certainty in maximum likelihood classification and methodologically Dempster's orthogonal sums. Unfortunately, accuracy for the whole data sets has not assessed yet, but accuracy assessments in training fields and check fields shows accuracy improvement over 10% in overall accuracy and over 0.1 in kappa index.

Change detection technology, which discovers the change information on the surface of the earth by comparing and analyzing multi-temporal satellite images, can be usefully applied to the various fields, such as environmental inspection, urban planning, forest policy, updating of geographical information and the military usage. In this paper, we introduce a change detection system that can extract and analyze change elements from high-resolution satellite imagery as well as low- or middle-resolution satellite imagery. The developed system provides not only 7 pixelbased methods that can be used to detect change from low- or middle-resolution satellite images but also a float window concept that can be used in manual change detection from highresolution satellite images. This system enables fast access to the very large image, because it is constituted by OGC grid coverage components. Also new change detection algorithms can be easily added into this system if once they are made into grid coverage components.

최근 GeoSensor 활용이 증가함에 따라 공간 센서 데이터와 같은 2차원 데이타를 효율적으로 처리하기 위한 질의 처리 시스템이 활발히 연구되고 있다. 하지만 기존 질의 처리 시스템들은 시공간 센서 데이터와 같은 다차원 데이타를 처리하기 위한 데이타 타입과 연산자를 지원하지 않기 때문에 이와 같은 다차원 데이터를 처리하기에 미흡하다. 따라서, 본 논문은 이러한 센서 네트워크에서 다차원 데이타를 효율적으로 처리하기 위하여 질의 처리 시스템을 개발하였다. 마지막으로 본 논문은 시나리오를 통해 본 시스템의 효용성을 검증하고, 수행시간 및 메모리 사용량 등의 성능평가를 통해 기존 시스템들보다 성능이 우수함을 입증하였다.

무선 통신 기술 및 GPS(Global Positioning System)등의 발달로 인하여 위치 기반 서비스 (Location-Based Services: LBS)가 크게 발전하는 추세이다. 그러나 위치 기반 서비스를 이용하기 위해 질의 요청자는 자신의 정확한 위치 정보를 위치 기반 서비스 제공자에게 전송해야 한다. 따라서 위치 기반 서비스를 제공하면서 질의 요청자의 위치 정보를 보호하는 것이 중요한 과제이다. 이 문제를 해결하기 위해, 기존 기법은 실제 사용자의 위치를 숨기며 네트워크 사용을 줄일 수 있는 2PASS 기법을 사용하였다. 그러나 이 기법은 실제 사용자 분포를 고려하지 않기 때문에 실제 사용자 위치 보호를 완전히 보장하지 않는다. 따라서 본 논문에서는 K-anonymity를 보장하는 가중치 근접성 그래프 기반 최근접 질의처리 알고리즘을 제안한다. 제안하는 알고리즘은 질의 영역 내 K-anonymity를 보장함으로써 사용자의 위치 정보를 보호할 뿐만 아니라 불필요한 질의 결과 탐색을 줄여 네트워크 효율을 증가시킨다. 마지막으로, 성능평가를 통해 제안하는 기법이 기존 연구에 비해 질의 처리 시간 및 네트워크 효율 측면에서 우수함을 보인다.
