This study aims to improve plans by analyzing spatial compositions of cohousing common houses, their role depending on the types of users and spaces, and satisfaction from the user-oriented design perspective. For this study, a basic concept was examined based on previous studies and literature reviews. So-Haeng-Ju(Happy House with Communication) Houses 1, 2, and 3 in Seongmisan Village was analyzed. As well, interviews with residents of these houses were conducted to analyze the role of user behavior in common house depending on the types of users and spaces. As a result, it was found that there were common characteristics of roles in an exchange with neighbors, cooperative child-care, and residents' meetings. The time and behavioral types were different depending on the living patterns, characteristics, and family members of residents. User satisfaction with the locations of community facilities including communal kitchen and communal living room, the composition of rooms, communication with residents, and the connection between communal living space and personal living space, was above the average. However, user satisfaction with storage facilities, or defect repair and facility maintenance was low. Most of cohousing common house users were satisfied with the use and size of spaces, and a sense of community, including communication with neighbors beyond the environment and Seongmisan Village. In conclusion, a realistic alternative is required for future cohousing by developing a system regarding human resources networks and cost bearing issues.

새로운 패러다임으로의 전이를 의미하는 과학혁명은 필연적으로 지적 영역의 변화를 동반한다. 더욱이 과학과 예술의 관계는 서로를 가능케 하는 상생의 관계라 할 수 있다. 최근 비선형 과학에 대한 놀라운 관심과 함께 예술에의 신속한 적용은 양자의 긴밀한 상호작용을 다시 한 번 가늠케 한다. 과학과 예술에 있어서 중요한 것은 새로운 창조의 과정과 방법을 제시하는 일일 것이다. 이를 위하여 때로는 역발상을 시도하고, 또한 일상을 탈피하여 예측할 수 없었던 것들을 추적하는 모험과 탐구정신이 절실하다. 이와 같은 관점에서 본 연구는 비선형 패러다임의 기저가 되는 카오스 이론과 함께, 물리학과 수학에서 다루어지는 관련 이론들을 준거로 하여 비선형적 공간조형을 재검토하였다. 연구 과정에서 비선형은 일련의 계(a system)에 대하여 부분이 아닌 전체로 보아야 할 것에 대한 강력한 제안이며, 또한 새로운 질서요 창조의 원리임을 확인할 수 있었다. 이울러 본 연구는 비선형적 공간 조형에 있어서 형태적 차용에 급급한 디자인 행위를 지양하도록 하는데에 암묵적 의도가 있었다. 따라서 비선형 동력학 현상의 원리와 프로세스를 이해, 적용함으로써 비선형이 지닌 창조적 속성이 공간에 총체적으로 발휘되기를 기대해 본다.

Modernity which is superficial phenomenon set off the mass scale for mass consumption and provide uniformly artificial environment. But natural destruction, environment pollution, resources exhaustion and so on has been caused by this and now ecology is threatened by destruction and damage beyond the limitation and human beings survival is even threatened. Accordingly furniture development for environment preservation considered environment problem is the urgent real situation. Recent paradigm is the concept of Eco-design which is the green design possible to live together in symbiosis, and new types of alternative furniture are needed in Korea as well. 'Furniture for disassembly' is presented as new method for alternative furniture. Furniture for disassembly can be presented by mainly two directions. The first main characteristic is what is assembled by the use of woodworking joints technique as an assembly structure system without any hardware. The second is what is presented as the structure possible to be assembled by simple manual tools with hardware without any glue. The advantages of furniture for disassembly are environment preservation, space application, transportation efficiency and shapeliness. In manufacture method which is different from present furniture, the application of traditional truss technique which uses various types of custom-made and connection technique in case of assemble structure system without hardware is the typical differences. This assembly method expects not only interest induction about assembly and disassembly of diagram per sub materials but also the development of emotion, the improvement of collaboration, space perception ability and shape sense, the improvement of solid body structure insight and so on, when it use in the furniture for children with the application to many kinds of structure with BANGDOOSANJ (Wedged), JUMUGJANGBU (Dovetail) or NABIEUNJANG (Dovetail Keys) and so on.

Unlike other body arts, body painting illuminates the value of art using eco-friendly formative activity and natural environment and highlights the need of eco-friendly activity. However, although body painting has focused on forming right relationship between human beings and nature, there are few researches which are linked with nature art. Therefore, the purpose of this study is to argue the need to study body painting as nature art in connection with natural environment and analyze body painting according to nature art types. The study methods included both theoretical review and empirical review. The theoretical review examined the concept and characteristics of nature art through previous researches and literature and the empirical review looked into the types and works of nature art and applied them to body painting works. The results were as follows. First, an installation type was possible by arranging and attaching certain materials to the body. Second, a physical type was possible by representing body itself as the part of nature. Third, a symbolic type was possible by making body appearance as a some symbol based on artist's idea. Fourth, a sound type was possible by stimulating auditory hallucination using the nature of objects and sensing a sound. Fifth, an ecological type was possible by conveying the message of living things in nature to the body. Sixth, an interior type was possible by inducing indoor installation of works. Seventh, a poetic type was possible by making one feel a poetic inspiration expressed in nature using the mystery of the sea and a simple sequential pattern of floral leaves. Eighth, a drawing type was possible by adding artist's intentional hand with a pictorical technique. Ninth, a indigenous type was possible by reproducing South American indian's primitive style. The review of this study suggests that body painting works have been expressed in experimental and temporary arrangement like nature art in nature and can be applied according to nine types of nature art.

In the early 20st century, created distrust on the mechanistic and dualistic view based on the world of Descartes and Newton. As the features of this new science cannot be explained by the existing Western philosophy but can be explained by the thinking system immanent in the Oriental traditional thought, many scientists and philosophers are concentrating their interests on the Oriental philosophy. In addition, some have been making efforts to find solutions needed for a new paradigm from the thinking system of the Orient. A variety of discussions have also been raised in connection with architecture due to this philosophical change. It has now become possible to conduct free creative acts, staying away from physical limitations, including gravity by diversified simulations through a computer. This physical liberation in turn has caused new changes to the spatial concept of architecture, thereby granting the freedom of the expression that could not be even imagined before and opening a possibility of new architecture and space. At the same time, the digital space architecture actively accommodating this technology is generating a phenomenon that the existing physical and realistic things are rapidly being changed gradually to immaterial and unrealistic ones. This study has analyzed the properties of digital architectural space as the immateriality of our traditional architectural space. The results are as follows: It can be seen that the immaterial features exhibited in the digital architectural space and the traditional architectural one are not just interconnected with specific features, but they are correlated to all immaterial features. Thus, immateriality that are common in the traditional and digital architectural spaces is complementary organic, which is contained in the ambiguity of boundary between other spaces. It is regarded to the architecture as a living things in space diversity based on ideological similarities.

Purpose - To meet the needs of various customers in an uncertain market environment, many companies use product modularization strategies. Modularization of a product means that one product consists of several components and that the type of product can be changed according to the combination of components. The greatest feature of modularity is that changes in one component do not significantly affect the physical changes in the other component to which they are connected. Modularization of products is recognized as a very important strategy to reflect increasingly complicated customer requirements to products and respond to the needs of various markets. Many studies have been made in connection with the concept of mass customer satisfaction. There are many prior studies that modularization of such products positively affects the operational performance (manufacturing cost, fast delivery, etc.) and innovation of the product. However, excessive modularization has been found to have a negative effect on this performance. However, there are very few studies on the nonlinear relationship between product modularization and customer satisfaction. Supplementing these academically insufficient parts is very necessary when considering the current market environment. Research design, data, and methodology - In order to make up for the shortcomings of academic research in Korea, this study collects data through questionnaires in electronic, auto, and defense industry. This is because these industries are using modularity of products. based on lots of previous studies and information overload theory, we made two hypothesis and verify with empirical analysis. All 108 data were used. We used the R program and SPSS program for statistical verification. Results - As a result of the study, modularization of products showed positive relationship with customer satisfaction to a certain level. However, it has been found that when the modularization is over and beyond a certain level, there is a negative relationship with customer satisfaction. Conclusions - Excessive modularization of products can have a negative impact on customer satisfaction. This result can be understood as a result of human limited rationality due to information overload. Therefore, it is important for companies to apply appropriate modularity to product design.

ATM 망에서의 장애는 가상 경로(virtual path; VP) 링크와 가상 경로 교환기(VP switches), 가상 채널 교환기(virtual channel switches)에서 발생할 수 있다. 이들 중에서 VP 링크와 VP 교환기의 장애를 복구하는 방법은 많이 연구되어 왔으나 보호 도메인(protection domain)의 종단점으로 사용되는 VC 교환기 장애에 대한 대응 방법은 아직 제안된 것이 없다. VC 교환기 장애는 단 한 번으로도 심각한 문제를 발생시킬 수 있기 때문에 이에 대한 새로운 고장 우회 방법이 절실히 요구된다. 지금까지 제안된 가상 경로 수준의 복구 방법은 크게 플러딩(flooding) 알고리즘을 사용하는 방법과 예비 가상 경로(backup virtual path; BVP)를 사용하는 방법으로 분류할 수 있다. 후자의 경우 예상치 못한 장애에 적절히 대응할 수 없다는 단점이 있기는 하지만, 복구 속도가 빠르고 필요 여유 용량(spare capacity)이 적다는 장점이 있다. 이 논문에서는 VC 교환기의 장애에 대응하기 위하여 새로운 형태의 BVP를 사용하는 복구 알고리즘을 제시한다. 제안된 알고리즘들은 공통적으로 VC 교환기의 고장으로 인해 단절된 가상 연결을 복구 할 수 있다는 장점을 가지며, 단순한 VP의 장애에 대해서도 기존의 연구와 비교하여 복구 능력의 저하가 없음을 실험을 통해 보인다.

본 논문에서는 USN과 기존 네트워크간 연동을 위한 보안키 관리 프레임워크를 제안한다. USN과 기존 네트워크간 연동은 다양하고 많은 디바이스로 구성되기 때문에, 인증기관(Certificate Authority, CA)의 부재에도 불구하고 공개키 기반의 암호기술이 사용되어야 한다. 제안된 메커니즘은 IP 네트워크의 PKI 시스템의 지원을 받지 못하는 상황에서의 공개키/개인키 관리와 디바이스간 인증에 초점을 두고 있으며, 인증기관 부재의 문제를 해결하기 위해 신원기반 암호화 개념을 도입하였다. 또한, 실제 네트워크에서의 적용가능성 검증에 초점을 두어 USN과 IP 네트워크 그리고 PLC네트워크를 연동하여 테스트베드를 구축하고, 제안 메커니즘을 적용하여 테스트하였다. 이러한 테스트를 통해 보안키 생성, 업데이트 과정에서 대칭키 기반 알고리즘과 유사한 성능을 확인하였고, 네트워크연동 및 장비인증이 가능함을 화인하였다.
