The purpose of this study was to understand and develop various environmental designs to play a key roles in urban design, so that public green spaces remain vital with future changes. Variability in space, ecology, and society were analyzed based on research of variable environmental spaces in 11 selected studies conducted locally and abroad since the 2010s. Moreover, landscape characteristics, design methods, and design strategies were analyzed accordingly for each case. The results of the study showed that variability in landscapes provided various possibilities for spatial change and satisfied people's functional needs for spatial use. In addition, variable environmental design greatly compensated for the defects by solving the issues associated with fixed landscapes by increasing the flexibility of use and adaptability to the environment. This study showed that variable design is applicable to public green spaces; environmental stress; and variability in architecture, the environment, and landscaping, and it contributes to enhancing the sustainability and resilience of the environment.

The objective of this study is to investigate the suitable spatio-temporal analysis method considering the zoning effect of spatial analysis termed the modifiable areal unit problem(MAUP). In former studies of spatio-temporal analysis, there were disagreement between attribute data with spatial data, because of variation of administrative district aggregating attribute data. It is need to consider how the analysis zone effects spatial characteristics and spatio-temporal variation of urban region through land price variation analysis. This study considers MAUP through basic mesh system, which is composed of micro grid. Mesh system can solve disagreement of resolution between spatial data and attribute data.

The Apartment resident's make-up of a family and residing preference are diversified by the change of lifestyle through the elevation of economy level and residing level. Accordingly, the remodeling and the early rebuilding for the satisfaction of a life cycle and a life style are increasing, and "Variability" that is the concept of Open Housing was emphasized as a central of residing plan in the apartment. Although apartments which select the space variability to the residing space are increasing gradually, the optimum composition structural system with space variability that satisfies the structure stability, the economical efficiency and the resident usability is not developed. The method of a study was progressed by a comparison and an analysis on each system with estimation elements through analyzing the development process and the special quality of existing composition structural system with space variability in the apartment. This paper offered the improvement direction on the current composition structural system with space variability for the development of modularizing system that is correct in domestic real condition.

본 논문에서는 행렬응축기법 및 부구조기법을 이용하여 가변형 입체 복합 공간 구조물을 효율적으로 해석할 수 있는 해석기법을 제안하였다. 최근 구조공학의 발전과 더불어 다양한 사회적 경제적 요구에 의해 가변형 입체 복합 공간 구조물에 대한 연구가 진행되고 있다. 가변형 입체 복합 공간 구조물은 많은 구조부재가 필요 하며, 부재 수가 많아짐에 따라 각 절점이 가지는 자유도수가 크게 증가하여 초기 해석 과정에서 많은 시간이 요구된다. 또한 구조물이 변경되는 경우에는 변경되는 부분의 강성의 변화에 따라 전체 구조물의 강성이 변경되므로 이에 따른 전체 구조물의 재해석 과정이 필요하다. 이러한 점에서 구조물의 자유도수를 줄여주는 행렬응축기법과 반복적인 해석과정을 줄여주는 부구조기법은 가변형 입체 복합 공간구조물을 효율적으로 해석 할 수 있는 방법이 될 수 있다. 본 논문에서는 행렬응축기법과 부구조기법을 이용하여 가변형 입체 복합 공간 구조물을 효율적으로 해석할 수 있는 해석기법을 제안하고, 이를 토대로 구체적인 알고리즘을 작성하였다. 또한 알고리즘을 구체화시켜 가변형 입체 복합 공간 구조시스템에 적합한 구조해석 프로그램을 개발하여 예제 구조물에 대하여 구조해석을 수행하였으며, 구조해석 결과를 상용프로 그램의 구조해석 결과와 비교하여 해석기법에 대한 정확성 및 효율성을 검토하였다.

Xmas(eXtensibla MAin memory Storage system)는 데이터의 지속성, 트랜잭션 스케쥴링, 동시성 제어, 회복 관리 등의 기능을 지원하는 주메모리 저장시스템이다. 최근 지리 정보 관리, CAD/CAM, 멀티미디어 등과 같은 새로운 데이터베이스 응용 분야가 증가하고 있다. 이런 응용분야들에서는 단순한 정수형, 실수형, 문자형 데이터 뿐만 아니라, 복잡한 다차원 공간 데이터를 빠르고 효율적으로 처리하는 것이 필요하다. 이런 공간 데이터는 그 크기가 가변적이어서 데이터베이스에서 이를 효율적으로 처리하기 위해서는 가변 길이 필드를 지원해야 한다. 본 논문에서는 Xmas의 고정 길이 필드 저장 구조를 활용하여 Xmas에서 가변 길이 필드를 지원하는 방법을 제안한다. 가변 길이 데이터를 고정 길이의 단위로 여럿으로 분할하여 Xmas의 고정 길이필드 저장 구조를 활용하여 저장함으로써, Xmas를 크게 변화시키지 않고 가변 길이 필드를 쉽게 지원할 수 있다. 또한, 가변 길이 필드에 대한 관리를 위해 스키마에 추가되는 정보에 대해 기술한다.

The space before modern times is fixed and closed, then that after modern times is flexible and open. Based on the concept of space, the modern art exhibition hall gradually shifts from the interior space of a building to the outdoor space, giving birth to the concept of outdoor art pavilion. Based on this background, we analyzed and learned about the latest deformable art pavilions, focused on the investigation of its space performance characteristics and the case analysis, fully understood the design principles of deformable pavilions, and proposed the basic design directions and strategies for future research. Firstly, through learning the theories of transformable space, the characteristics and concept range of deformable space are understood. Secondly, based on the preliminary research and analysis of art pavilions, the performance characteristics are summarized. Thirdly, the pattern of deformable space and the method of reflecting the characteristics of deformable space are investigated based on cases. After summarizing the case analysis, we identified the differences of different art pavilions between deformable modes and space characteristics, and analyzed the causes. This work provides a basis for distinguishing the transformation patterns of the deformable space, and reveals the changes in space concepts and the expansion of space meaning in future architectural space design.

This study is on the spacial flexbility of house. In the recent days, it is true that the qualitative aspect of residence rather than the quantitative one has emphasized. But the inhabitants of residence undergo adaptation problems to deal with changing needs constantly. Residence must be the place to satisfy inhabitant's desire to live and dwell. According to changes in family life cylce and personal demand, the flexibility in housing should be beneficial. This study attempts to solve relationships of these need changes and inhabitant's adaptation through the spatial flexibility. Throughout the process of main discourse, some theoretical backgrounds of housing are applied. And to introduce the flexibility of residential space, concepts of flexibility according to 'time' and 'spatial structure' are employed. In addition to functionality and comfort, living should provide a touch of humanity attuned to individual sensibilities. The purpose of this study is to suggest a method can move interior structure by the flexible planning.
