Despite the advancement of knowledge and techniques, architectural design has been developed by similar method and science as the logical tool since the development of Le Corbusier's 'module'. However, in the new millenium emotional design has become a key issue and today is the turning point regarding new method for designing human space. While architecture discipline of the West focused on logic, Japan based its origin in eastern discipline has developed a unique design concept called 'metabolism' and advanced it very effectively. Since its development of the unique concept, Toyo Ito has become one of the most Influential architect in and out of Japan who devoted his design career in developing new space concept. This study is specifically focused on Ito's project by finding characteristics of his projects and analyze emotional design factors by using 5 analytical tool - experiencing the space, five senses, landmark, sequence, and scale. Ito's work between 2000-2004, such as Sendai Mediatheque, showed more visible sign of emotional design characteristics compared to the works done in 1990's. Because of the analytical studies researching those emotional design characteristics and methods, the future advancement in new space design will be possible with great success. The result proves that continuing proper analysis and research in design method will assist in approaching new space design method into more advanced realm in very efficient time period with more definite design elements to accomodate and fulfill human needs in given space.

이 연구는 학교도서관 이용자의 요구 변화와 그에 따른 학교도서관의 역할 변화를 수용하기 위하여 학교도서관의 IC 도입에 대하여 연구하였다. IC 개념을 응용하여 학교도서관에서의 IC 구성요소를 도출한 후 도입 모형을 제시하는데 연구목적을 두었다. 특히 학교도서관의 IC 구성요소 도출 및 IC 도입 모형 구축에 초점을 맞췄다. IC 구성요소는 물리적 요소를 학습공간, 제작공간, 커뮤니티공간, 서비스 데스크로, 인적 요소는 사서교사, 정보기술자, 학생도우미로, 서비스 요소는 정보활용교육과 협력적 통합서비스로 세분하였다. 마지막으로 도출한 IC의 구성요소를 바탕으로 학교도서관의 IC 서비스 개념도, IC 도입모형, IC 평면도를 제시하였다.

Ron Arad, the master of contemporary design in the U.K., is one of representative leaders of this age who has left distinguished achievements in the history of contemporary design through innovative design. Analyzing and understanding the Deconstructive design concept and the deconstructive characteristics of interior space of Ron Arad will contribute to finding directions for today's design and laying the ground for explaining the development pattern of design in the 21st century. After analyzing the deconstructive characteristics of each selected space, One Off and Ron Arad Associates have shown a deconstructive design trend of a creative formula by using methods that shed conventional processes and material while a space composition and form of new concept was attempted in the resting space of the New Tel Aviv Opera House, offering not only the establishment of a new circulation system, but also diverse experiences of space to visitors. Likewise, a temporal experience and communication between the user and the space was attempted in Belgo Noord and Belgo Central by partially applying a narrative space composition that sheds existing design concepts. At the Millennium House, they have produced an interior space for future house developed by breaking off from existing typical design development work and material through computer operation, and made various forms of space and atmosphere possible by attempting variable elements and the use of ultramodern material. Y's fashion shop has granted variability to the form and volume of space according to time by presenting display elements that have shed existing form and function. Hotel Puerta America as well, with a curved structure that has broken off with existing forms and maximized space variability through structures that have utilized ultramodern materials and instruments. Through this study, it has been verified that Ron Arad has been unraveling connections between interior space and its user, its requirements, and the original unique principles of space by applying deconstructive design concepts, and that through the mediation of these spaces, he is attempting indirect communication with the user. Eventually, he is taking part in the harmony and development of all elements of space connected with human beings by applying deconstructive design concepts.

This study focuses on Gilbert Simondon's individuation theory, a core concept of his technological philosophy, and spatial modality in interactive space as the schema of interactive operation. The study examines spatial modality as the technology of an interaction-enabler that has archi-semiotic characteristics in the designed space by aspects of examples. They are based on ideas and properties of a combined environment and the concept of information, which form Simondon's individuation theory. In the process of technological individuation, spatial modality has the characteristics of archi-semiotics from a combined environment and information. The first of the three properties is representation through semiosis and the information surface. Second is the context by relation works and perception, and third are the symbolic aspects, which could create Placeness by meaning. Combining meaningful constructive and deconstructive spaces could result in space for interactive communication. Spatial modality makes it possible to interact with users and spaces. In fact, it could have a particular semiotic mode of address and become a semiotic and contextual base. As a basic investigation of spatial modality, this study will contribute to interactive space design research.

During the modern age, various fields have fundamentally changed from the preconceived ideas of the past. The concept of time-space relationship changed also. E. J. Marey was almost the first one to visualize the movement of animals and people through scientific methods. Frank B. Gilbreth used more precise photographic equipments to develop more accurate and specific body movement diagrams. The emergence of visualization of body movement is not the only product from the scientific field. The new concept of time-space can be easily noticed in modem art, music and dance. In space design, Futurism attempted to represent the dynamism and speed in a sculptural form. On the other hand, there were examples to further investigate the specific analysis of body movements such as 'Scientific Management'. Body movement diagrams are widely used in various projects in contemporary space design. The difference is that now the design process is more integrated with the analysis. The representation of speed and the container of movements are interwoven in a complex manner in which fluid relationship between body and space is possible. Three types can now be considered: Object, Container and Interactivity. This study attempts to analyze brief history of body movement studies and their application for contemporary space design.

The development of digital culture has brought radical change in the fundamental concept of what workspace is defined by and has also switched the cognition of workspace originally being a place to spend time and do activities regarding tasks into space more than just that. If we take a look at the cases overseas firms have announced after the year 2000, we can find distinguishing facts different from the existing workspace composition, like creative workspace, amusement workspace, workspace for communities, etc. Thereupon, the goal of this research is to look into the domestic characteristics of workspace by investigating and analyzing case by case targeting domestic firms. This research is to first comprehend the theoretical study of workspace, the changing environment, and the characteristics of domestic workspace, going on to utilizing the information achieved above to analyze 8 appointed domestic firms as examples. Contemporary domestic workspace is defined not a place only for activities regarding work tasks but rather a place comfortable and friendly in the concept of a second residence, community node for sharing knowledge and information, mobile space for the digital nomads, and space for coincidental encountering and communication. Based on this the analyzed characteristics of contemporary domestic work places are metaphor, convergence, beyond boundary, and emergence. The characteristics mentioned above are considered elements that increase corporate profits by managing efficient smart-work and producing creative ideas. Therefore, I believe continuous research and development related to this subject is necessary.
