In this paper we propose a new algorithm which extracts spatial arrangement information of texture elements in structural textures. In the proposed algorithm, by the use of projection information in several directions obtained from the texture image we can get two directions which determine the texture structure and the parallelogram grid which isolates texture elements. The isolated texture elements are analyzed and used to synthesize texture images. Computer simulation shows that the proposed method can extract proper spatial structure of the texture element even when the texture image is highly corrupted by additive noise.

Under passive RFID environment, this paper presents a new localization of a mobile robot traversing over the floor covered with tags, which is superior to existing methods in terms of estimation performance and cost effectiveness. Basically, it is assumed that a mobile robot is traveling along a series of straight line segments, each segment at a certain constant velocity, and that the number of tags sensed by a mobile robot at each sampling instant is at most one. First, for a given line segment with known starting point, the velocity and position of a mobile robot is estimated using the spatial and temporal information acquired from the traversed tag. Some discussions are made on the validity of the basic assumptions and the localization for the initial segment with unknown starting point. Second, for a given tag distribution density, the optimal tag arrangement is considered to reduce the position estimation error as well as to make easy the tag attachment on the floor. After reviewing typical tag arrangements, the pseudorandom tag arrangement is devised inspired from the Sudoku puzzle, a number placement puzzle. Third, through experiments using our passive RFID localization system, the validity and performance of the mobile robot localization proposed in this paper is demonstrated.

Among the unearthed House ruins in Gyeongju of the capital of Silla period, the ruins to see the overall appearance of building arrangement is the ruins of Silla capital S1E1 area, Inwangdong 412, and the Jaemaejeong. In this study, the characteristics of urban house arrangement of the Unified Silla period was analyzed that, through a review of the arrangement relationship between the gate and the individual buildings found in these ruins. The urban house of the Unified Silla period was surrounded with wall, and the way to distinguish between functional areas within it are shown differently, depending on the size of the house. In other words, the small house was divided each area by installation of inner fence, and the large house was by arranging attached buildings. Thai is, the central area is not divided by inner fence is the Characteristics that is different from the small house. And in all houses, a large courtyard is located in the front of main building. Conatruction of the courtyard determines the location and direction of the main building. And the each area has external space of courtyard in the center.

The objective of this study is to investigate the functional conformity based on the analysis of the spatial connectivity of block housing using space syntax. Three cases were selected which have important meanings in 1920s. The properties of spatial configuration were derived from an urban-context approach and without urban context analysis, and spatial connectivity and functional conformity were analyzed using references. The results of the study revealed that the arrangement of block housing were different from one another notwithstanding their similar layout characteristics. The relationships between urban streets and housing complexes were identified, and the public spaces were being arranged as semi-public spaces, whereas blocks as private spaces by separating functions. This study provides the implications for the planning of low rise-high density housings by means of analyzing the spatial connectivity of the spatial layout characteristics of European block housing, recognizing the relationships between urban communities and housing complexes.

Recently, women's fear of crime continues to increase in space of everyday. By the way, the fear of crime has the spatial properties as crime. Therefore, The purpose of this study is to evaluate the spatial dependence of fear of crime and to suggest the physical environmental factors influencing fear of crime. For this, a spatial regression analysis using spatial weights was conducted based on the location data of the fear of crime measured through a survey. The results of this study are as follows; First, the fear of crime felt by women in their twenties who are vulnerable to crime has spatial dependence. Therefore, it is necessary to consider the spatial characteristics in analyzing the environmental factors affecting this. Second, in order to reduce the fear of crime, it is necessary to improve the environments of old housing and entertainment facilities. There is also a need for ongoing management. Third, careful consideration is needed in the installation of CCTV and street lights, which are factors influencing the fear of crime. It is necessary to establish a reasonable arrangement standard for CCTV and to analyze the street lighting in detail.

In this study the spatial distribution characters of forest in forest damaged area were first considered by analyzing spatial data and monitoring forest landscape. Then suitable tree species on each site were selected through the weighted score analysis of GIS analysis methods. Finally, the best forest stand arrangement method could be presented on the 3D based simulation system for the advanced reforestation technology in Korea. For this purpose, the virtual reforestation system was implemented by using the concept of virtual GIS and CBD (Component Based Development) method. By use of this system the change offorest landscape of burnt forest area some years after reforestation practice could be detected and monitored by applying the site index and 3D modeling method.

본 연구는 전통사회와 현대를 이어주는 제례(祭禮)가 의례(儀禮)의 전승(傳乘)이라는 관점에서 제례진설에 나타난 상징성의 의미를 분석하고자 한다. 전통의례의 삶과 죽음에 대한 유교적 생사관과 사상적 바탕이 되었던 음양오행론, 우주구조의 이해와 사시(四時)의 변화로 나타난다. 제사상의 진설이 조상의 존재를 인정하고 상징체계를 통해 산 자와 죽은 자가 시간과 공간적으로 소통하는 의례적 도구로 이해하였다. 또한 사계절과 하늘·땅·지하의 공간을 제수(祭需)의 선정과 배열을 통해 상징화하고 구체화하였다. 현대 제례진설에서 위치를 결정하는 요인은 대상에 대한 시·공간적 분석을 필요로 한다. 이는 제물이 기능적 역할 뿐만 아니라 제물을 통해 표현하고자 하는 시·공간적 상징성으로 이해되기 때문이다. 본 연구에서는 제례진설에 나타난 사상적 배경과 상징체계에 대한 논의를 통해 제례문화의 계승이라는 관점에서 고찰하는데 의의가 있다.

The traditional housing of Cheju Island has been steadily researched, but from the point of an environmental view which has been neglectly treated all the while, the formative process of the housing and its relationship to the structure of a village are studied, so the writer summarized the relation to the housing type. To study the peculiarity of the physical space, a type of a way, and element of the spatial structure, by stage and a type of the arrangement of the residential space are researched and analyzed, and to understand the plane peculiarity, the distribution of the plane type has been studied. In consequence, the housing and the structure and the form of the village have an organic relation each other and have been made under a very diverse and mixed background, we can find. Especially, the element of the natural environment acts as an important element which decides the type of life and the residential type. The arrangement of buildings is gradually free from the traditional type, but a traditional type of "Three-Room House" is kept well in spite of a change of the plane type.

신 재생에너지에 대한 건축물 인증제도, 공공건축물 신 재생에너지 투자의무비율 확대 등 다양한 건축물 신 재생에너지 설비투자 지원정책으로 건축물 지붕을 활용한 태양광 사업 추진이 빠르게 확대되고 있다. 이러한 건물 지붕을 활용한 태양광 설비는 인접 건축물 또는 자체 구조물이나 시설에 의한 정밀한 음영분석이 필요함에도, 설계자의 경험이나 단순 그래픽툴에 의해 배치 설계가 이루어지고 있는 실정이다. 본 연구에서는 건축물에 소요되는 에너지 일부를 지붕형 태양광 설비에 의한 생산전력으로 대체하고자 할 때, 특정 선정기준에 따른 태양광 어레이의 최적 배치안을 선정하는 프로세스 모델을 구축하고자 한다.
