Purpose: Pungsu is can be seen as an ecological architectural science regarding native natural environment of east asia. Even though the language used in Pungsu is different from that of ecological architecture, Pungsu considered the surrounding environment of the traditional house by various Pungsu method for making and keeping more healthy life and sustainable environment. The research is for finding out how the surrounding natural environment was considered with Pungsu, a traditional ecological architectural science in case of site selection and planning house by the confucian scholar in late Joseon period. Method: Sudan Nam-Gyu Lee's traditional house of Yesan in the middle of korea is selected. The study is processed as follows. The site was analyzed with feature and flow of mountains expressed as dragon in chapter 2 and four important hills around the house are analyzed in chapter 3. Finally Pungsu applied in architectural space is analyzed in chapter 4. Result: we can see that the traditional house of Sudang Lee Nam-Gyu has been planned considering Pungsu in details to minimize the negative factors and utilize the positive factors of nature as much as possible thinking nearby natural environment as environmental factors that can affect the residents of the house through Pungsu.

In the face of the new dimension of the developed technology $L{\acute{a}}szl{\acute{o}}$ Moholy-Nagy, a master of 'the Bauhaus Akademie', made an effort to constitute the integrated life of the intellectual and the emotional by translating the experiences of the new technology Into the emotional language and the cultural realities. As an artist who criticized in the constructivist ethos the conception of the image as the imitation and brought the Image movements into relief Moholy-Nagy groped for a new expressive idea that can be called as 'the idea of the non-representational spatial expression' in which the expressive elements interact one another. His idea of the non-representational spatial expression that is made up of the pure forms of the nature, the direct colors and the spatial elements is oriented to incorporate the modern realities, i.e. the space experiences as the complicated sensory workings and the new technology as the measure of the human thinking, and further to see where they will move to. This study is on the one hand purposed to explicate the fundamental idea of the non-representational spatial expression that was poorly illuminated in spite of its importance in the respects of the design and art history, on the other to re-actualize the implications of the space-design which are contained in it.

This paper presents the unique formation process of a volumetric space with the digital algorithm developed for Voronoi diagram in order to generate an effective parametric architectural form. By applying systematic parameters of architectural conditions within digital parametric tools, the interactions among sub-spaces developed by Voronoi diagram are enhanced by manipulating the spatial structures. In this paper, we discuss how the parametric distributing and zoning geometrical system can support designers in developing a free-formed space, and research on how this system creates a 3D volumetric space. With the in-depth research on the system and structure of Voronoi diagram, the approaches to the application of Voronoi diagram into architectural form generation are clarified to be an effective, creative and successful digital tool. The result of the application of the Voronoi diagram improves the design quality with systematic language in the sense that the sub-regions are created and controlled under the systematic and balanced hierarchy having dynamic relationships among each others with the restoration of the equilibrium of forces and tensions. This 3-dimensional Voronoi diagram provides another means for designers to solve architectural issues and to reinforce their design concepts.

Indoor space has been one of the focal points for geospatial research as various factors such as increasing demands for application and demand for adaptive response in emergencies have arisen. IndoorGML (Indoor Geography Markup Language) has provided a standardized method of representing the topological aspect of micro-scale environments, with its extensive specifications and flexible applicability. However, as more real-world problems and needs demand attention, suggestions to improve this standard, such as representing IndoorPOI (Indoor Points of Interest), have arisen. Hence, existing algorithms and functionalities that we use on perceiving these indoor spaces must also adapt to accommodate said improvements. In this study, we explore how to define spatial neighborhoods in indoor spaces represented by an integrated IndoorGML and IndoorPOI data. We revisit existing approaches to combine the aforementioned datasets and refine previous approaches to perform neighborhood spatial queries in 3D. We implement the proposed algorithm in three use cases using sample datasets representing a real-world structure to demonstrate its effectiveness for performing indoor spatial analysis.

The purpose of this study was to analyze the space of upper class housing in Andong through the oral life history of women in terms of sexual life. Even though the living was centered on women, the women of Joseon were alienated from the history. For this reason, the life history of head family housing was not recorded in the language of women, and often passed on orally. Also sexual life is a important part in daily life, but it is hard to be recorded or mentioned in Confucian society, and there is not much space research related to sexual life. Now there is not a lot of head family housing left, and the number of people who can tell the life history which is not recorded and the storyteller is also decreasing. From now on, I will record what I have experienced or passed through interviews of the residents living in head family housing and then analyze the characteristics of the sexual life.

The current trend of low cost ultra-small satellites is to utilize Commercial Off the Shelf (COTS) parts to save cost, and accordingly, Command and Data Handling (C&DH) that operates the satellite and collects/processes the data is also designed and developed around commercial controllers. However, functionalities of commercial controllers are limited according to the specs outlined by the manufacturer. In order for the commercial controllers to be used for satellites where variety of interfaces is required, a separate interface circuit is required. Therefore, a Multi Digital Data Control System (MDDCS) using Field Programmable Gate Array (FPGA) has been developed in order to expand multiple digital interfaces that are not supported by the commercial controller, and also to compensate for SEU. This has been implemented on Actel A3P1000 using Very High Speed Integrated Circuits Hardware Description Language (VHDL).

Informatics curriculum has been revised for informatics principles and concepts to effectively teach. According to the revised curriculum, researches are verifying the educational effects of algorithmic thinking and problem-solving abilities using programming language by applying it to various area. However, researches in programming education considering the level of student are yet incomplete. This research has analyzed the impact of the perceived level of problem solving on the performance of project completeness. As results of difference of project completeness, a high perceived level of problem solving group's performance of project completeness was higher than a low perceived level of problem solving group's one. Analysis of the impact of the perceived level of problem solving on the performance of project completeness, 'problem finding' factor had a significant impact. This research suggested the importance of 'problem finding' and self-reflecting introspective 'reviewing' stages in problem solving process using programming language.abstract of your study in English.

Computer applications for engineering design evolve rapidly. Many design frameworks were developed by the simulation based systems so that organizations could achieve significant benefits due to cost reduction in designing. However, today’s transient design issue requires being adaptable to more complicated and atypical problems. In this paper the Multidisciplinary Language Runtime (MLR) design framework is developed. The MLR provides flexible and extensible interface between analysis modules and numerical analysis codes. It also supports Meta Modeling, Meta Variable, and XML script for atypical design formulation. By applying object-oriented design scheme to implement abstractions of the key components required for iterative systems analyses, the MLR provides flexible and extensible problem-solving environment.
