In this paper, we propose an optimal camera placement using agent-based simulation. To derive importance of space and to cover the space efficiently, we accomplished an agent-based simulation based on classification of space and pattern analysis of moving people. We developed an agent-based camera placement method considering camera performance as well as space priority extracted from path finding algorithms. We demonstrate that the method not only determinates the optimal number of cameras, but also coordinates the position and orientation of the cameras with considering the installation costs. To validate the method, we compare simulation results with videos of real materials and show experimental results simulated in a specific space.

Ecosystem and environment have been a serious challenge facing the modern society. It's been the new paradigm from ecological view of the world and the alternative based on Orientalism. From the Oriental standpoint, ecological aesthetics and sustainable architecture are no longer new, which then servers the background of this study. The nature and the space, the life where the human is harmonized and integrated and the wish to make the balance through that life are the basic philosophy which the Orientalism has pursued. Based on such a basic concept, the study is intended to review the connectivity, expression approach and the features in Korean traditional residential space based on previous studies on ecological aesthetics and sustainable architecture. Such attempt is meaningful in seeking the possibility of presenting the new frame as well as forming the various views to the traditional space and spatial recognition. The nature was categorized into tangible element and intangible element and also direct approach and indirect approach before evaluating the characteristics. Sustainable architecture is not the concept to simply maintain or sustain the environment, but plays more important role in economical aspect. Traditional space accommodates the nature and circulation principle and the circulation in the nature controls the energy and enhances the efficiency, playing significant role. The nature itself serves the alternative energy and has the aesthetic element in such a way of concealing itself. This study is intended to analyze the Byulseo Jeongwon which formed many relations with the nature and the residential space, thereby identifying the expression characteristics of eco-aesthetic sustainable architect. This study offers the answers with regard to the coexistence of the expression characteristics of sustainable architecture with the nature, space and the human from eco aesthetic viewpoint as well as the solution in dealing with the ecological and environmental challenges. Furthermore, it suggested the possibility that the traditional space would possibly be succeedable in new and creative way and sought the way for coexistence among the nature, space and human and eco aesthetics, and finally paved the pivotal foundation as the sustainable design alternative in future.

In the late 1970s, the method of quantitative and scientific space structural analysis based on graph theory was introduced to the process of space design, which arranges design and functional elements, as relying heavily on intuition could produce errors due to unverified experiences and prejudices of the designer. As the method of space analysis is complex and hard to express visually and requires repetitive operations, it was discussed theoretically only. However, with the development of computer performance and graphic in recent years, visualization became possible. But the method of visual structural analysis of space is at the level of two dimensions and it is not easy to get accurate data when it is applied to limited three dimensional space such as an interior space. For the visual structural analysis of space, this study presents 4 indices including visibility volume level, pure visibility connection frequency, effective visibility connection frequency, and path visibility connection frequency. This study also presents space division using three dimensional arrangement rather than the existing vector operation method and raytracing algorithm at the lattice constant. Based on this, an analysis tool for the visible regions of three dimensional space that is capable of evaluating at multiple points by using three dimensional game engine and presentation tool that allows the analyzer to interpret the data effectively is made. It is applied to 2 prototype models by displacing Z axis, and the results are compared with UCL Depthmap to verify the validity of data and evaluate its usefulness as a multidimensional, multi-view space analysis tool.

The purpose of this study had started from trying to look for a new standard in new media era and sounding out possibility of perspective of digital poetry, and had been extracting interpretational elements based on characteristics of otology in digital poetics research in technical method. Through examination of many documentary records, we suggested interpretive elements of medial space based on meaning and the theory of digital poetics. We deduced three perspectives based on relationship between the basic thesis in poetics and interpretive elements of medial space. We used them as tool for analysis of example. We chose as an example that change of program in space is clear through connection of media and space in where new form of creation happens through digital instruments and chose article as subject to which digital technology is applied and had been since 2000, The result of this study is as following: First, epistemological analysis about a space of digital media in new media era requires poetical approach unlike aesthetic approach. We can endow creative action and creation process with significance and pay attention to technical method of manufacturing, stating appropriateness of perspective in digital poetics. Second, the justice of digital poetics and its basic thesis help derive analytic elements from medial space and study purpose of production, technical method, ontological characteristics, which are three perspectives of digital poetics. Third, it analyzed characteristics of example according to three perspectives above and we can analyze characteristics of spacial expression in space of digital media into potential, trans-active, and semiosis space. It would be possible through analyzing examples in digital poetic perspective to overlook new methods of design in 21th and various perspectives and possibilities of medial space design.

For guaranteeing for security of nuclear power plant, ergonomic factors have been applied to design of main control room, core area for management and control of nuclear power plant, but design elements for performance of operators have been ignored. As the behaviors of operators are important for security of nuclear power plant, space design which makes them pleasant psychologically and makes them maintain attention on security equipments ceaselessly is required. Therefore, the purpose of this study is to analyze space characteristics of main control rooms according to regulations of nuclear power plant and general guidelines of space design, and to offer basic data for designing of main control room which makes operators pleasant psychologically and physically. At first, theoretical issues related with design of main control room are reviewed and several premises of space are developed by abstracting design elements from common space and regulations of nuclear power plant and, then integrating each design elements interactively. In short, the improvement of system environment based on human-machine interface space has brought about perceptual, cognitive, and spatial changes and has realized next generation of main control rooms. And, differences and similarities between ordinary space and main control room, which ergonomic sizes and regulations are applied and is VDT environment based on LDP, are discussed in relation to 13 design elements and 17 space premise.

While most GIS are based on Euclidean space, cellular space can be used as an alternative type of space for a large number of GIS applications. In order to analyze the pattern of moving objects in cellular space, we need new definitions of similarity between their trajectories since the trajectory in cellular space significantly differs from those in Euclidean space. In this paper, we study the properties of moving objects in cellular space. Based on these observations, we propose several similarity measures between trajectories in cellular space. We analyze the difference of the proposed measures by experiments.

As population inflows into the city and the traffic volume increases, a three-dimensional transportation system was developed, and as a result, the lower space of the viaduct was formed. Since the space under viaduct includes factors such as shadow, noise, vibration, and disconnection between regions, efforts have been made to prevent slumming and help form local communities by activating them. This study intends to derive analysis based on locality, functionality, and communication for a variety of access to the lower space of an overpass, and analyze cases based on the result. We have the results through analysis are as follows. First, the space under the viaduct has been turned into a slum due poor accessibility and utilization, and local residents and local government also neglected the space. However, it appears to be a space with high potential utilization. Second, by giving diversity to the lower space of the viaduct and cultivating spatial identity, the space was activated and connected with the surroundings by providing a more pleasant environment. Third, accessibility was improved by providing a complex functional and aesthetic environment, and by providing various programs that could form a community among residents, voluntary and active participation was elicited.
