Objectives: Spatial analysis is useful for understanding complicated causal relationships. This paper focuses trends and appling methods for spatial analysis associated with environmental asbestos exposure. Methods: Literature review and reflection of experience of authors were conducted to know academic background of spatial analysis, appling methods on epidemiology and asbestos exposure. Results: Spatial analysis based on spatial autocorrelation provides a variety of methods through which to conduct mapping, cluster analysis, diffusion, interpolation, and identification. Cause of disease occurrence can be investigated through spatial analysis. Appropriate methods can be applied according to contagiousness and continuity. Spatial analysis for asbestos exposure source is needed to study asbestos related diseases. Although a great amount of research has used spatial analysis to study exposure assessment and distribution of disease occurrence, these studies tend to focus on the construction of a thematic map without different forms of analysis. Recently, spatial analysis has been advanced by merging with web tools, mobile computing, statistical packages, social network analysis, and big data. Conclusions: Because the trend in spatial analysis has evolved from simple marking into a variety of forms of analyses, environmental researchers including asbestos exposure study are required to be aware of recent trends.

The purpose of this study is to show how to gain the morphology of the Hybrid Spatial Structures and to get the geometrical data such as node coordinates, member relationships and graphic images. To form spatial structures, we have developed morphological aspects of general spatial structures, programming process and techniques. Structural design has many processes. Especially, it is very important to consider the determination of structural configuration. Regular Hybrid Spatial Structures have complex configuration, so we need to make use of automated computer process to determine structural shape in Hybrid Spatial Structures. We have applied morphological aspects to double layer plate, single layer dome, double layer dome and tensegrity structure.

본 연구에서는 우리나라의 수치지형도를 객체지향적 설계 분석 방법을 통해 객체화하기위한 실험적 연구이다. 객체지향 개발에서 가장 중요한 고려요소인 캡슐화, 다형성, 상속등을 통해 가능한 정보은폐된 수치지형도 객체를 설계하였다. 이를 이해 수치지형도의 자료모형을 분석하고, 지도 사상들 간의 상호관계를 계층적으로 파악하였다. 이로부터 현재 수치지형도의 레이어 구성은 공간자료모형이나 자료 정의의 측면에서 개념적으로 정의한 계층이 실제 자료 특성에 모호하게 반영되어 이를 구체화하기 어려운 구조를 갖고 있음을 밝혔다. 이러한 한계 때문에 '자료 레이어' 단계와 '객체 클래스' 단계를 통합하여 객체의 계층을 구분하였고, 수치지형도 공간 원형 클래스를 정의하여 이를 통해 공간 객체를 자신의 자원으로 활용하는 연계 매커니즘(ISCO)을 통하여 수치지형도 레이어 객체들을 설계하였다. 그리고 설계한 수치지형도 객체를 JAVA를 통해 구현한 다음 실제 웹 인터페이스를 통해 인터넷 환경에서 편리하게 상호 공유하여 수치지형도 객체의 효율성을 검증하였다.

오늘날 공공도서관은 정보제공뿐만 아니라 문화생활 기능 제공 등 그 역할이 변화하고 있으며, 도서관 공간 역시 도서관의 서비스를 반영해 변화하고 있다. 본 연구는 이러한 도서관 공간에 대한 탐색적 연구를 수행하고자 한다. 본 연구는 도서관 공간과 이용자의 도서관 인식 간 상관관계를 탐색하고, 도서관의 물리적 특성을 기반으로 도서관 공간 유형을 제안하는데 그 목적이 있다. 본 연구를 위해 관찰조사 및 설문조사를 수행했다. 관찰조사 결과, 도서관의 공간 유형은 '분리형', '부분통합형', '완전통합형' 세 가지로 나타났다. 본 연구에서 제안한 공간 유형의 타당성을 검증하기 위해 통계 분석을 수행한 결과, 공간 유형에 따라 이용자의 도서관 인식과 이용 목적에서 유의한 차이가 나타났다. 즉, 도서관의 공간 구성에 따라 도서관 공간을 유형화할 수 있으며, 공간 유형이 이용자의 인식에 영향을 미치는 것으로 판단된다. 본 연구는 이제까지 고려되지 않았던 도서관 공간과 도서관 인식 간의 관계를 탐색하고, 공공도서관에 대한 긍정적인 인식을 형성하는데 적합한 도서관 공간 구성을 제안했다는데 그 의의가 있다.

Although Space Syntax is a well-known technique for spatial analysis, debates have taken place among some researchers because the Space Syntax discards geometric information as both shapes and sizes of spaces, and hence may cause some inconsistencies. Therefore, this study aims at developing methods to recognize and manage spatial shapes for more precise space syntax analysis. To reach this goal, this study employed both a graph theory and binary spatial partitioning (BSP) tree to recognize and manage spatial information. As a result, spatial shapes and sizes could be recognized by checking loops in graph converted from spatial shapes of built environment. Each spatial shape could be managed sequentially by BSP tree with hierarchical structure. Through such recognition and management processes, convex maps composed of the fattest and fewest convex spaces could be drawn. In conclusion, we hope that the methods developed here will be useful for urban planning to find appropriate purposes of spaces to satisfy the sustainability of built environment on the basis of the spatial and social relationships in urban spaces.

Modern architecture tends to split the everyday life and the space of human. Position of architecture should be on the relationship between nature and human need. It will be study on the everyday life of architecture from architecture and everyday life of human relationships. Based on this study, it makes clear the visual aspects of architectural experience to acquire spatial tones for analyzing architectural Everyday-ness. In this case, Portugal's modern architectural space was impressing, because of the construction of local color and architectural vocabulary of the Everyday-ness. Therefore, the Everyday-ness of Architecture by relationship analysis reveals the space of these spatial tones. Spatial characteristics of the Everyday-ness of architecture be analyzed of simplicity, purity, locality, reminiscent, continuity, and transition, etc. Expression elements of spatial tones can be derived into five classes such as light, color, material, pattern (texture), and depth. In conclusion, spatial characteristics of the Everyday-ness and expression elements of spatial tones consist of configuration matrixes to analyze the spatial tones of the contemporary architecture in Portugal. As a result of this study, the expression characteristics of spatial tones of contemporary architecture in Portugal are background-ness, one-ness, and inherence. I hope this study will be applied to the basic data of the architectural Everyday-ness.

Multi-family housings caused several problems related to physical form such as isolation of housing estate, inhumanity of the exterior space, and mismatch with the urban structure. To handle these problems, the purpose of this study is to analyse density elements which have a direct impact on physical forms, thereby understand the characteristics of physical form and also identify a meaning of inter-relationships between them. Therefore both formal constituents and density elements are reformed into respective analyzing indices. From the analysis, physical form and the spatial layout of buildings were more uniform in large-scale housing estates than in medium or small housing estates. However, small-scale housing estates showed various form and the spatial layout of buildings in order to increase the building density.

This study aimed to investigate the canopy growth conditions and the accuracy of phenological stages of paddy rice using ground-based remote sensing data. Plant growth variables including Leaf Area Index (LAI) and canopy reflectance of paddy rice were measured at the experimental fields of Chonnam National University, Gwangju, Republic of Korea during the crop seasons of 2011, 2012, and 2013. LAI values were also determined based on correlations with Vegetation Indices (VIs) obtained from the canopy reflectance. Three phenological stages (tillering, booting, and grain filling) of paddy rice could be identified using VIs and a spatial index (NIR versus red). We found that exponential relationships could be applied between LAI and the VIs of interest. This information, as well as the relationships between LAI and VIs obtained in the present study, could be used to estimate and monitor the relative growth and development of rice canopies during the growing season.

This paper describes a framework for multimodal object manipulation in virtual environments. The gist of the proposed framework is the semantic integration of multimodal input using spatial ontology and user context to integrate the interpretation results from the inputs into a single one. The spatial ontology, describing the spatial relationships between objects, is used together with the current user context to solve ambiguities coming from the user's commands. These commands are used to reposition the objects in the virtual environments. We discuss how the spatial ontology is defined and used to assist the user to perform object placements in the virtual environment as it will be in the real world.
