A new IRF (Impulse Response Function) analysis technique in high resolution SAR image is presented by taking into account the real clutter environment. In order to investigate the realistic effect of clutter background on the impulse response function of SAR image, an ideally generated impulse response function is superimposed with a large number of background clutter data which are extracted from the various regions of an actual SAR image. As a performance measure, PSLR (Peak Sidelobe Ratio) of the clutter-contained IRF is presented in the various groups of clutter background, and finally the results are compared with the stochastic model.

The Arches cluster is a young (2-4 Myr), compact (~1 pc), and massive (${\sim}2{\times}10^4M_{\odot}$) star cluster located ~30 pc away from the Galactic center (GC) in projection. Being exposed to the extreme environment of the GC such as elevated temperature and turbulent velocities in the molecular clouds, strong magnetic fields, and larger tidal forces, the Arches cluster is an excellent target for understanding the effects of star-forming environment on the initial mass function (IMF) of the star cluster. However, resolving stars fainter than ~1 $M_{\odot}$ in the Arches cluster partially will have to wait until an extremely large telescope with adaptive optics in the infrared is available. Here we devise a new method to estimate the shape of the low-end mass function where the individual stars are not resolved, and apply it to the Arches cluster. This method involves histograms of pixel intensities in the observed images. We find that the initial mass function of the Arches cluster should not be too different from that for the Galactic disk such as the Kroupa IMF.

Track-before-detect techniques based on dynamic programming have provided solutions for detecting targets from a sequence of images. In its application to airborne threat detection, dynamic programming solutions should take into account the distinguishable properties of objects in a collision course. This paper describes the development of a new track scoring function that accumulates scores for airborne targets in Bayesian framework. Numerical results show that the proposed scoring function has slightly better detection capabilities.

The space in today's digital era is developing in a new direction with the changing paradigm, which is different from that in the analog era. The space that appeals to the advanced technology mobilizes all the five senses of the space user with the technical elements of the more variable fields and aesthetic productions, and creates an interactive environment by motivating the user's active participation through the digital media. The environmental device called digital media connects the function pace with living performance. Unlike in the analog space, the different sides of the digital media space create a human consciousness that corresponds to the realistic ambience, further contributing to the lively condition. For the main production technique in the digital medias performance-active space, there are electronic image production, changeable production, impromptu-active production, light and sound production, and total artistic production that lead to the progressive interaction between man and space.

The importance of communication which is oriented to interaction, fusion and connection is more increased in the post-information society. The information environment is already realized as interface to reach immediately and freely to the databased information and knowledge. The contemporary libraries execute very important roles as an intellectual infra of modern times to deliver the great human achievement and create new culture. In the mean time, the rapid information-oriented society and the development of digital technology bring out big change in the traditional dispatch and receipt method of information. For this reason, libraries as the community space of visitors integrates physical space - electronic space and reconstructs new temporary culture and value to build the new interface that connects human to human, human to space and human to information. On the premise of these awareness, this study analysis the creative interface factor of Tama Art University New Libraries in Ito Toyo in order to research the function and the application method of modern libraries. And the results are follows. 1)We can make sure the significance of communication and the integration consciousness between digital technology and analogue sensitivity that is the characteristic of the post-information society. 2)We can classify for the creative interface factors by the character as space factor(Arcade, Gallery, Lounge, AV Booth, Cafe), facility/equipment factor(Laboratory, Media, Bar, Info Shelf, Media Seat) and furniture factor(Carrel, Desk, Mag Table, XI Shelf). 3)We can see that these interface factors change the stream of library users and that the library is constructed for library users to create and discovery something easily from books and modern technologies. And we can realize also that these factors are creative installation to lead out naturally the latent liberty sense of users.

This study aims to suggest the Deconstruction theory that is changing and developing by being converted into visual from as cultural code which reflects the spirit of the times and art style as well as to analyze the phenomenon of deconstruction expressed in the Fashion photographs. Fashion photographs are historical documents presenting us with the evidence of the ideal body types and culture throughout time. Fashion photographs is direct information about the fashion itself, and at the same time, it transmits various circumstances of the times. Fashion photographs has opened a new aspect called visual communication, when it's seen in new, more profound way, instead of being locked in its visible frame. Photograph is no longer a mere means to preserve documentation or pursue artistic expression. Instead, it's now regarded as a way to pursue visual transmission owing to its cognitive psychology, and this is a remarkable step toward new thing. In this study, the possible visual information function of photograph was explored from diverse aspects, such as the combination of photo and design, its linking to printing technology's mass production function, or the development of its imagery symbolism. This study shows that the nature of deconstruction can be explained as deconstruction of the sexes, deconstruction of the time and space, and deconstruction of the genre.

Recently general hospitals in Korea have been actively remodeled. Remodeling is required to extend the hospitals' area and to meet the new medical demand. Eventually it aims for achieving ideal healing environment. Seoul National University Bundang Hospital has also developed the schematic design to open the new hospital in 2012. This large scale of extension is the first step in its expected remodeling cycle. It is essential for the extension of hospital to create an architectural system on the basis of function, and to keep the balance with both the existing buildings and natural context simultaneously. To connect the existing hospital and the new hospital, a hospital street should be designed to make it function as a main pedestrian spine. Space design marketing of general hospital is effective in promoting the hospital image. It can be realized by emphasizing hospital identity through combining cultural program and commercial facilities. Developing hospital design should be encouraged under the EBD (Evidence Based Design) concept spread in USA.

초광대역 (UWB) 신호의 정밀한 시간 해상도는 실내 환경에서의 위치추적 등, 다양한 응용을 가능하게 하는 동시에, 사간 오차에 대한 감도가 매우 높아지는 등, 시스템 설계 시 기술적 어려움을 주기도 한다. 신호의 시간 해상도를 평가하는 유용한 방법 중 하나는 신호의 ambiguity function을 평가하는 것이다. 이 논문에서는 기존의 ambiguity function과는 달리 시간 오차와 시간 스케일링 인자를 두 변수로 하여 펄스 방식의 UWB 신호를 위한 ambiguity function을 정의하였고, 임펄스 라디오 (impulse radio)의 송수신 방식에 따른 UWB ambiguity function을 평가하여 시스템의 타이밍과 관련된 이슈들을 논하였다.

New images percolate through human consciousness by the media such as movies, TV programs, and brilliant advertisements. These images reproduce new ' things ' throughout the ' semantic processes ' by those who experience and recognize them. Alvin Toffler describes it as the ' information bomb ' and ' image fragments ' in his talk about the new paradigm of information-oriented era. The increasing number of images and their accelerating rate of appearance imply that images become more momentary, and are evidence that they are transforming entire human life and consciousness. Such awareness means a lot to a designer. Especially, the subject that how modern space-dominating images are related to the structure and materials constituting the space and communicate with human mind will be an important factor in establishing the human-space relationship in the future. Furthermore, the present age overspread with various medium is not the only one privileged of the images that exist within space. They are the results of continuous expansion of existing images, and also process of evolution of space powered by the fusion of images and digital media. Imagified space is a boundary layer of Cyberspace, and the space itself becomes an interface by human recognition and participation. Now, the functional classification of spaces such as ' office, ' ' cafe, ' and ' school ' is meaningless. Whatever it may be, the function of a space is defined by the information it interfaces, and therefore it becomes an interface to information through a large number of images. Based on this idea, we will observe the imagificaiton of space in the form of discussion, and from that, try to understand the phenomenon through the real world examples.

Preservation space is a functionally$\ulcorner$core$\lrcorner$in a museum. Gernerally, it is a common view that collections are exhibited within 5% of total stored collections. So that, part of collections are cycled exhibition space centering around preservation space, and that is a important mechanism of collections circulation in a museum. It is the best way that collections should be $\ulcorner$conserve$\lrcorner$ in a stable condition, but inevitably collections are exposed as stable condition, but inevitably collections are exposed as called $\ulcorner$exhibition$\lrcorner$. For that reason the function of $\ulcorner$exhibition$\lrcorner$. For that reason the function of $\ulcorner$exhibition$\lrcorner$for 'showing' and the function of $\ulcorner$preservation$\lrcorner$for 'conserve'are contrary to each other's concept, so it is principle of scheme that these concepts should be functionally connected with and planned$\ulcorner$match$\lrcorner$. In addition, various studies (for example, comparative analysis of collections, examination of collections for conserved condition or special exhibition, and classification of new item, etc.) are worked in preservation space. Therefore, preservation space should not be considered as a warehouse, should be composed not only$\ulcorner$comfortable place to rest of collections$\lrcorner$but also $\ulcorner$part of study room$\lrcorner$in a museum. So that, environment of museum should be established by plan to preservation and management. The point of plan to museum is that minimize dangerous element for collections, and then develop an essencial element of space for$\ulcorner$conservation$\lrcorner$and$\ulcorner$exhibition$\lrcorner$. The reason why with a few exceptions (buildings which have being exposed or extremely minor part of collections) most of collections have been lasting its life during over hundreds of years with adapting itself to natural features, so scheme of preservation facilities should be made up with understanding and analysis generic character of collections, and then establish proper temperature and humidity environment.
