The problem of defining the relationship between interior space and exterior envelope of a building has long been a challenging task in the field of architecture throughout its history. This research chronologically reviews some of the important turning points in various schools of thoughts concerning construction of exterior envelope, with focus on how they influenced and altered the formation of our interior environment. This research also stipulates on how technological advance in the late 20th century laid grounds for a new type of interior-exterior relations in architecture through creation of flexible and ambiguous boundary conditions. The focus of this qualitative research will be on contemporary works of Japanese architects Toyo Ito, SANAA, and related group of architects who address the issues of transparency, flexible interior layout, buffer zones, structural facade, and neutralized (homogeneous) space that produces spatial quality of non-linear, non-hierarchical, and de-materialized space as a direct alternative to modern principles of space making.

The main gate of a university is a element of landscape which improves the quality of campus as well as demarcates the boundary and publicizes the image of university. Therefore, each university strives to differentiate its main gate from that of other universities with a unique form. This research investigates the signs and symbols shown at the university's main gate of 18 universities in Korea, and also presents useful design tips with the objective of bearing the spirit of the campus and its founding ideology. The results of this research as follows: Icons of Sign for 18 universities can be classified into five separate categories: things, human, animal, character, and metaphor. Examples of the 'things' icons include a pen nib, the sun, the cross, a big bell, and so on. Also, the meaning of the represented symbols can be grouped in three separate categories: university's development, contribution to society, and mining of knowledge. From the three category, university development symbol is the most likely to be used.

Purpose: The purpose of this study were to analyze ultrasonography on both sides of gastrocnemius medialis of stroke patient. Methods: In fourteen subjects with stroke, the gastrocnemius medialis(GM) muscle were scanned with ultrasonography at the muscle belly at rest at ankle angles of 0 degree (neutral position) and it were measured with ultrasonography on both sides of the leg. Muscle architecture (thickness, pennation angle, fascicle length, density, white area index) was examined using real-time B-mode ultrasonography with 7.5MHz linear-array prob. Results: Thickness of non-paratic side was significantly thicker than paratic side. Pennation angle of non-paratic side was significantly larger than paratic side. Fascicle length of non-para tic side was significantly smaller than paratic side. Density of non-paratic side was significantly smaller than paratic side. White area index of non-paranc side was significantly smaller than paratic side. Conclusion: This study showed that stroke have influenced on mechanical properties and quality properties of skeletal muscle architecture.

Service identification and composition is one of the key characteristics for a successful Service-Oriented Computing, being receiving a lot of attention from researchers in recent years. In the Service-Oriented Analysis, the identification of business services has to be preceded before application services are identified. Most approaches addressing the derivation of business services are based on heuristic methods and human experts. The manual identification of business services is highly expensive and ambiguous task, and it may result in the service design with bad quality because of errors and misconception. Although a few of approaches of automatic service identification are proposed, most of them are in focus on technical architectures and application services. In this paper, we propose a model on the automatic identification of business services by horizontal and vertical service alignment using Enterprise Architecture as an ontology. We verify the effectiveness of the proposed model of business services identification through a case study based on Department of Defense Enterprise Architecture.

In modern society, it is necessary to develop sustainable housing to protect environment. There should be a study on long life housing that satisfies living condition which residents require. Long life housing research is already activating in many developed countries. Although activation of long life housing is urgent, domestically, immaturity of technology development and law and system are barrier to progression of long life housing. Increase of early construction expenses is also problematic in activation of long life housing. The purpose of this research is to clarify a necessity of long life housing, to provide high quality of sustainable residence and to protect environment. This research also suggests a need of change from previous housing to long life housing. Moreover, it will look at related law and system of domestic long life housing and compare it to international law and system. From this comparison, it will point out a need of improvement and suggest appropriate long life housing system.

A townscape has both aspects of seeing and living. However, the main streams of townscape making have been mostly focused on the former perspective so far. Such trends are apt to lack the realities of urban living. In this view, a prerequisite to complement the existing formalistic view with this realistic one is needed in order to accomplish the holistic characteristics of a townscape. Many city governments of Korea are currently trying to improve the quality of living quarters by providing diverse kinds of open spaces such as vest-pocket parks, pedestrian-friendly streets, and supporting the residents participatory village making. In this context, this paper will review the possibilities of the realistic approaches in townscape making by examining some current cases being tried in Korea cities. In conclusion some main issues to be solved in future can be listed as the conflict between general citizen′s view and the residents′ view", the conflict between social aspects and aesthetical aspects" and the conflict between the tradition and the vernacular reality in design".

Data assimilation is an initializing method for air quality forecasting such as PM10. It is very important to enhance the forecasting accuracy. Optimal interpolation is one of the data assimilation techniques. It is very effective and widely used in air quality forecasting fields. The technique, however, requires too much memory space and long execution time. It makes the PM10 air quality forecasting difficult in real time. We propose a fast optimal interpolation data assimilation method for PM10 air quality forecasting using a new kernel tridiagonal sparse matrix and CUDA massively parallel processing architecture. Experimental results show the proposed method is 5~56 times faster than conventional ones.

The color gamut mapping method that is used for enhancing the color reproduction quality between PC monitor and printer devices is adopted for display quality enhancement. The high definition display devices operate at the clock speed of around $70\;MHz\;\sim\;150\;MHz$ and permit several nano seconds for real-time processing. Thus, the concept of three-dimensional reduced resolution look-up table is used. The required hardware can be greatly reduced by look-up table resolution adjustment. The proposed hardware architecture is successfully implemented in ASIC and also successfully adopted in display quality enhancement purposes.
