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.

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.

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.

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.

본 연구는 우리나라 유리건축에서 적용되고 있는 유리투과체를 조사하여 투과율이 다른 4종류 즉, 투명유리, 색유리, 파스텔유리, 로이유리를 선정하여 복층유리로 제작하였다. 투과체에 따른 실내공간의 채광성능평가를 위하여 축소모형을 1/10으로 제작하였으며, 투과체의 구성을 일반형과 이중분할형으로 구성하여 기준실과 실험실에 설치하였다. 또한, 채광성능평가시 IEA모니터링 프로토콜을 적용하여 작업면, 벽면, 천정면에 대하여 조도를 외부조도와 동시에 측정하였고, 본 논문에서는 작업면에 대한 채광성능평가를 중심으로 분석하였다. 평가지표로서 주광조도비를 사용하였으며, 일반형과 이중분할형에 대한 가변 유리투과체를 변화시켰을 경우 투과율에 따른 실내공간의 채광성능을 평가하였다. 가변 유리투과체로 구성된 실내공간의 채광성능평가는 다음과 같이 분석되었다. 첫째, 실내공간에 일반형을 적용하여 서로 다른 투광성능을 가진 유리투과체가 적용된 경우 외부조도에 대한 내부조도 비율은 투과율이 증가할수록 일정하게 증가하는 것으로 나타났다. 이는 투과체가 갖는 투과성능의 영향으로 판단된다. 둘째, 일반형에 비해 이중분할형은 채광창으로 유입되는 채광학적 기여가 증가하여 실 전체의 조도를 증가시키며 특히, 실 중간부와 후면부의 경우 채광적 잠재력이 증대되어 실의 쾌적함과 시 환경적 질이 증대될 것으로 사료된다. 현재 유리건축물에 많이 적용되고 있는 저 투과체에 이중분할형을 적용할 경우 채광학적으로 많은 효과가 있을 것으로 기대된다.

As the change in social awareness regarding cats is consistent with the lifestyle of modern people who seek an independent life, the number of cats owned as a pet and its market will continue to increase. The compainion animals are not just pets to pet owners, but people communicate with their pets and the pets have begun to be recognized as a member of their family. Although the pet industry has been steadily growing and the number of cats owned by households is rapidly increasing, there is a lack of study on products based on understanding the characteristics and behavior of cats. The purpose of this study is to propose a versatile furniture design considering the behavior characteristics of cats. The versatile furniture that is easy to move and rearrange according to necessity and the environment of residential space always pays to make better use of the space. We would like to propose versatile furniture that can satisfy the aesthetic pleasures of cats and can be used as furniture at the same time depending on purpose and situation. This study aims to develop the design of furniture that can make a better environment for pets and pet owners, an it is expected to be a basic study of furniture design for them.

The purpose of this study was to analyze the flexible system in a typological way that develops and promotes the various methods of flexible system. The main method of this study was literature review and content analysis on various flexible systems and a case study of flexible housing. The flexible system in this typological analysis was classified into two categories: 'Elements of Flexibility' and 'Variation'. The category of Flexibility Elements was categorized into 'Primary Elements'(e.g., walls, floors, and ceilings),'Secondary Elements'(e.g., doors, windows, and furniture), and 'Tertiary Elements'(e.g., lighting, hues and finishing materials). Variation Effect was classified into 'Visual Variation', 'AppBicative Variation', and 'Layout Variation'. Also, Variation could be classified into 'Finish-centered', 'Application-centered', and 'Layout-centered' The flexible system developed in this study is a basis for further concrete flexible methods.

In this study, by comparing the development and the space types of local and foreign flexible apartments, basic data will be derived for the development of various flexible types of apartments in Korea. A total of 60 unit plans, including 30 domestic cases and 30 overseas cases of flexible apartments, are analyzed for this study. In terms of the unit plan types, Korean apartments usually had a wide front bay with shallow depth, placing more rooms on the front bay; whereas foreign apartments tend to have various unit plan types: (1) a narrow front bay with deep depth, (2) a wide front bay with shallow depth, and (3) variegated open-plan types. Many apartments in foreign countries had a double-layered structure with the. upstairs and downstairs areas. In terms of the flexible types, many Korean apartments achieved interior flexibility using non-bearing wall or sliding doors; whereas foreign apartments had a flexible space by separating the support elements and the infill elements. There was found to be a close relationship between the location of support elements and the variability of unit plans. Support elements can be placed largely into three locations: (1) Between the front side bay and the rear side bay, (2) in the center bay of a unit plan, and (3) others. Depending on the location of support elements, various types of flexible unit plans can be created. Through a comparative analysis of domestic and foreign apartments, basic data that can be used for developing various flexible unit plans was derived.
