Since the late 20C, the development of informative electronic technology has expanded human beings' spatial recognition from three-dimension into multi-dimension. Also space has formed mutual organic relation with the human being, since they started having the image responding ability of experience and recognition. The mutual organic relation has appeared in exhibition space aggressively introduced informative electronic technology from existing physical space. Therefore, m carried out a compartive study into the status of exhibition facilities and the form of interaction focusing on exhibition facilities as a medium of interaction between information and users in experiential exhibition space to which informative electronic technology had been introduced. The ultimate purpose of the study was that the phenomena, which had been anticipated from happenings in mutual organic relation between human beings and space, was reflected on space as a place of various communication activities. Hereafter, researches and studies on further exhibition should be continued to clarify the mutual relationship between exhibition space and user trends not only through exhibition space but also through the study of user trends that are changing everyday.

Temperature-dependent current-voltage characteristics of organic light-emitting diodes(OLEDs) were studied in a device structure of ITO/TPD/Alq$_3$/Al to understand conduction mechanism. The current-voltage characteristics were measured in the temperature range of 8K ~ 300K. We analyzed an electrical conduction mechanism of the OLEDS using space-charge-limited current(SCLC) and Fowler-Nordheim tunneling. In the temperature range above 150k, the conduction mechanism could be explained by space charge limited current from the inversely proportional temperature dependence of exponent m. The characteristic trap energy is found to be about 0.15ev. At low temperatures below 150k, the Fowler-Nordheim tunneling conduction mechanism is dominant. We have obtained a zero field barrier height to be about 0.6~0.8eV.

This study aims to understand the ornamental space in Art-Nouveau style which was made up the ornamental aspect and spatial aspect. So that It is needed to classify the ornamental space into three categories according to the way of construction; pictorial composition, non-objective composition and organic construction. To find the meaning of these ornamental spaces, works of Art-Nouveau are analyzed into ornament and space, in result we know that process of integration, relativity of ornament as a part and forms of expression in ornamental space have some regulation; use of natural motive, repetition of image and organic combination. Whereas the ornamental space in Art-Nouveau style has comprehensive capacity between antagonistic relations just like tradition and new mechanism, the space could receive a lot of different ideas and express these ideas as ornaments. Although the ornamental space also had weak points which were the lack of transformation and the difficulties of the application of other design due to the perfection itself, we could create new space which meets the requirements of the times, if we develop and make up for the weak points in the ornamental space under the principles of dialectic.

Interactive space became one of the modern contemporary society design paradigms. For elevating the interactive effect, we need Interactive design development which uses the influential factors on the interactivity. Digital technology is resulted in a change to a society as well as to the life of human and its way of communication. This study is inquiry into the relations and the common characteristics between ecological architecture space and eco-centric environmental philosophy by making a comparative research. This aims to examine type of spatial contexts for performed through literature research for theory by interactive space and case studies for ecological construction elements to design. And the range of case study is limited to interaction space in addition of interactive elements and user interface. And analysis conclusion is show the many type. Five principles that draw at ecological design conceptualization process, whole unity, variety of organic at ecological design conceptualization process, circularity, homeostasis, allness, biological evolution, diversity have involved with concept that presents in ecological esthetics and organic property of ecology-system.

The concept of surface has become more relative and more relationship-oriented based upon interaction between spaces as the traditional realm of perception succumbed to that of a more flexible, open perspective. If surface characteristics are consideredas an interface, an interface with individual characteristics will form part of the whole and will become an element in the whole (the environment), manifesting itself as a medium incorporated in an architectural space. This authorintends to understand interface not as a mere intermediary space but as an intervening border that allows exchanges between different environments and as a medium that allows expressions of aesthetic order through organic order. Also, it is the Intention of this author to grasp extended meanings of interface.

This research focuses on similarity evaluation of images according to tones of images. Color space of images were converted RGB color space into HSI color space. The information entropy criteria has been taken for evaluating similarity of images for digital library. The similarity was then calculated by combining correlation coefficients and information entropy. Those two values are further analyzed with a relation to human sensibility.

In contemporary architecture, Environment is not just a non-objective space. It is an experimental space where physical space and the principal result of interaction and order have been granted in symbolic, introverted space. Therefore, Yokohama International Port Terminal characteristics that appear in the architectural space, the nature of human desires and reveal the value of user-centered criteria to classify the type of response characteristics of the affordance are as follows; First, the experience response in the affordance reaction is when users reaction is multiple in theenvironment. Second, the evolution of organic reactions in a public space system is that it shows the spatial characteristics of the functional relationships. Third, the organic of space that can be seen through cultural practice in the inside and outside of the space could be explained as a perceptual response. It can be an opportunity to analyzed and develop in a various forms of space in environmental design if we understands the spatial characteristics of FOA's Yokohama International Port Terminal and applied end user spatial reaction analysis that shows an affordance relationship study.

This study represents something in common and differences of organic characteristics between early modern architecture and contemporary architecture analysing F. L. Wright's Robie House and Toyo Ito's Sendai Mediatheque. A natural organic body cannot be separated from the natural environment, and each part of an architecture has each own property and forms a whole at the same time. That is a basic concept of organic architecture, and a framework for analysis is set up based on it. The followings are similarities and differences of organic concept and interpretation between Wright's Robie House and Ito's Sendai Mediatheque First, Wright' Robie house unites with the natural surrounding, using a physically close connection to the ground. In contract, Ito's Mediatheque shows characteristics of noncentural and fluidic space that are metaphorically reflecting tangible and intangible of factors in modern city, where there is an ambiguous physical boundary between architecture and urban environment. Next, floors, walls and ceilings of Wright's housing as for basic building blocks are physically separated and at the same time form formative unity from the point of view of a physical and structural organic body. And continuous flow of faces of separated walls form an organism united with the nature from a physical aspect. On the contrary to this, there is an no-boudary and floating organic architecture of integrated structure from ambiguous setting of relation between architecture and urban space in Ito's architecture. Especially, Mediatheque shows semantic integration of floating urban environmental factors through horizontal and vertical integration of horizontal slabs, vertical pipes, and skins. Last, horizontal and vertical factors of Wright' Housing is appreciated as an basic experienced structure in terms of spacial perception and fluidic inner spaces in Wright's housing is completed with a series of spatial experiences in a visual sense. On the other hand, no-boundary and floating space of Ito's architecture accept user's physical and virtual body. Especially, there is an integration transcending beyond time and space, accepting an imaginary body and events with the course of time at Ito's Mediatheque.
