Information theory is one field of the applied mathematics quantitating the data in order to store data as many as in the medium or communicate through channel. it was released on the Shannon's paper, in 1948. With basis on this paper, It has been achieved dramatically development for communication, signal processing, and date procedure and transmission in the network In this paper, the basic concept of information theory is described through dealing with contents about meaning of information, entropy, and channel capacity. It is also handled how information theory is applied to the fields of sensor network, relay channel, MIMO system, and others.

Alois Riegl's aesthetic theory of visual perception provided one of important conceptual backgrounds for Vienna Art Nouveau architecture. Riegls theory of visual perception consists of geometric style and two-dimensional transformation. Riegl's theory of geometric style is based on the modern aesthetic theory of abstraction, which says that the artistic perfection can be obtained not from a direct imitation of natural objects, but from an abstract transformation of them. Riegl's theory of two-dimensional transformation, on the other hand, aims at obtaining artistic perfection by disintegrating volumetric conditions of natural things into planes and combining the planes thus obtained into another new world of art. These two theories of Alois Rigl's provided an important aesthetical background for the design strategy of 'abstract ornamentaion of two-dimension' in Vienna Art Nouveau architecture. This paper is to review the basic concept of Alois Rigl's theory of geometric style and two-dimensional transformation.

The robot localization problem is a key problem in making truly autonomous robots. In this work we provide thorough discussions of Ultrasonic Positioning System can be applied to the localization problem. First, we look at the use of Kalman filters and basic concept and the equation involved in Kalman filters. Secondly, we create understanding of how the Kalman filters can be implemented in robot localization. We show our discussion and experiments how Kalman filters applied to the localization problem. Lastly, we perform simulations using Usat Wheel Chair robot in our own general Kalman filters robot monitoring software.

The purpose of this study is reserch the approch and basic principle which make it possible to establish the consistent and subjective direction on the proportion method of DAPO HAPGAK STYLE House in the traditional Korean architecture. The object of reseach which should be considered in dealing with traditional concept on proportion are as follows. What is the proportional method in the plane of the Korean traditional archtecture. In this study, it was intended to find out that, what was the basis of numerical system implied in the proportion system of Korean traditional architecture and whether there can be the absolute and ideal relatioship between proportion systmes or not.

This research deals with the residential environment for the elderly and describes characteristics to give a positive effect on elderly's health and quality of life in Sweden. Five elderly care home recommended by a municipality staff in Stockholm are surveyed on $01\~03$ October 2003. The results of this study are as follows: 1) homelike atmosphere is regarded as a basic design concept and is applied to size, materials, scale, color, and furniture of elderly housing in Sweden, 2) regarding of the exterior features, it is similar to the ordinary house rather than institution building, 3) arrangement of spaces is planned for several small groups consisting of 6-8 residents, 4) open-space planning on public kitchen and dinning room allows residents to feel comfortable when they can hear a sound and smell a meal, 5) private flat is to provide amenities for sleeping, rest, storage, social interaction, meals, hygiene and other every activities

This Study is about the check-List composition for 'Low carbon green growth' of Long-life housing. That utilization for required the check-list composition at Sustainable building strategies and Design methods. That for long life housing, sustainable building strategies part of building construction and interior, the proper foundation for legislative system, maintenance methods with in building life cycle, sustainable and green architecture capability realization prepare for connection plan with 'Low carbon-green growth'. Extracting from elements of Architectural planing answer to basic concept of Low carbon-green growth and aimed at Low carbon scheme for energy saving, green growth scheme for environmental conservation as to each application purpose reconstitute by classify Check-list category about elements of Architectural planing. Through this architectural research deduce elements of architectural planing that can be research utilization with in Check-list composition.

The purpose of this study is to suggest an environment-friendly design method of ecological architecture complex, with the reference to foreign cases. The ecological architecture is very similar to the natural ecosystem, but there is increasing international scientific consensus that human activities are having a discernable effect on the global climate. The most important thing is keep going harmoniously between preservation and development relevant with nature. In the process of ecological approaching concept, we need a method that from "architecture in a nature" to "architecture as one section of the nature" would be extended further, also the purpose of this study aims to achieve these kinds of ecological architecture. As a result of, in this Age of industrial science, we are proposing useful materials and suggestion regarding the ecological architecture planning of Korean cities, by preestimating the characteristics of a city heading toward the Age of the new ecological environment.

[Purpose] Recently, skyscrapers have sharply increased throughout the world, including South Korea. Although a skyscraper has its own merit such as the landmark of a city, it also has various problems like massive energy consumption. This study is aimed to establish the concept of environment-friendly skyscraper and propose a plan to realize skyscraper after analyzing the architectural, facility and environmental friendly elements of skyscrapers. [Method] This study lists up skyscrapers over 40 floors and 200 meters high. Upon 10 constructed buildings, it analyzes their basic plans and the green building technologies applied to them and suggests effective and environment-friendly architectural plan. [Result] This study examined the distinctions of the layout, shape, facade, and floor plan plane of 10 skyscrapers and found out specific techniques to be used for the use plan of natural energy, plan for saving resources and reducing wastes and a plan for environmental architecture and system.

The first four generations of computers are all based on a single basic design: the Von Neuman Processor, which is sequential and does one operation at a time. Efforts to develop concurrent or parallel computers have been carried on for many years. Data flow approach is significant in these efforts to make high speed parallel machines and expected a great deal of parallelism. In this paper we propose a preliminary data Flow Machine Model operating asynchronously on the base of Node Labelling. We introduce a concept of Node Labeling for this purpose which is relevant to the Data dependency and Parallelism. And we explain how the Node Tokens are fired in the proposed system.
