The soil-structure interactions are caused by the point sources of explosions, deriving piles, compaction of foundations and excavations those are frequently arose in the construction sites. Thus the analysis of soil-structure interactions is one of the most important subjects in the fields of dynamic analysis and vibration control. From this viewpoint, the aim of this study is to collect the basic data for designing foundation structures throughout understanding the dynamic structural behavior, which is embodied by the dynamic analysis of soil-structure systems. In this study, the dynamic analyses of stiffened thick plates subjected to in-plane stress on elastic foundations are carried out. The foundation is modeled as Pasternak foundation that includes the continuity effect of foundations. Also both the Mindlin plate theory and Timoshenko beam-column theory are used for analyzing the thick plates and beams, respectively.

Until recently, dentistry did not show notable social conflicts with other medical professionals. This means that conflicts did not surface as medical doctors took the dominant position even though areas of intervention have been overlapped. The recent conflict between medical professionals, which began with clashes in the area of oral and maxillofacial surgery, have been embodied in the Supreme Court ruling on the use of Botox by dentists and the court ruling on the use of oral devices in oriental medicine. We look discuss at each case in detail to seek a solution to the problem of interprofessional conflict. We present professional duty of self-development and interprofessional education as a way to resolve disputes between medical professionals, which would be a major problem in the future of dentistry and medicine.

In this raper, proposed easy half-wavelength LPF and acceptor structure in actuality manufacture using EBG (Electromagnatic Bandgap) structure for application of micro-strip circuit. Because conventional half-wavelength LPF and acceptor is narrow line-width of High impedance, actuality manufacture is difficult. Width that in proposed structure narrow microstrip line of High impedance EBG structure use and has equal impedance embodied to wide microstrip line. Also, it is seen that actuality manufacture is available applying to half-wavelength LPF that have cut-off Frequency of 3GHz.

디지털 기술의 발전은 다양한 정보들과의 새로운 상호작용들을 창출하고 있고, 여기에서 인터페이스는 상호작용을 가능하게 하는 구체적인 장으로서, 우리가 정보들과 갖는 상호작용 방식을 규정한다. 그런데, 확장현실이나 유비쿼터스 컴퓨팅과 같은 새로운 기술적인 흐름들은 우리의 물리적 공간에 디지털 정보라는 무형의 층위를 더함으로써, 현재의 손과 눈의 작용을 중심기반으로 하는 상호작용 방식들로부터 발전된 형태의 상호작용이 필요하게 될 것임을 시사하고 있다. 이에 본 논문에서는 물리적 공간 안에서의 우리 자신을 형성하고, 세계를 인지하는 근간이 되는 신체에 초점을 맞추어, 신체가 새로운 정보 환경 속에서 정보의 인지 메커니즘과 상호작용의 주체로서 어떻게 기능할 수 있을 것인지를 메를로-퐁티의 현상학과 구현인지 이론을 바탕으로 탐구하고, 그 실질적인 예와 가능성들을 인터랙티브 아트 작품들에서 찾아본다.

Currently the indication method of the traffic signal light which is established in our country displays each "red, yellow, green" using the brightness LED signal light. In this paper, one LED circular arrangement replaces the Current indication method of the traffic signal light using two color LED. Also the blinking signal function of present time uses the MCU of AVR series and it is embodied with magnification and abridgment of the circular arrangement for recognizing easily far away. The signal light indication method which is proposed will be able to substitute the signal light of 3 colors with 1 signal light with economic profit presented the reform measure of energy efficiency improvement together.

The cultural identity of design is very critical in the modern society which is called the society of complex culture and multi-culture. In addition, adopting a traditional lattice-like pattern as a composition element of interior space is an effective way in the context of adding a traditional touch to the modern interior space. Meanwhile, in the process of applying Korean traditional lattices to modern interior space, some problems occurred: it has not been properly embodied; or it has been mistaken for those of China and Japan sharing similar culture with Korea. Thus, this study is designed to have precise knowledge of Korea, Chinese and Japanese traditional lattices. Besides, typical patterns of each nation's lattices are comparatively analyzed from the geometrical viewpoint, in a bid to pave the way for th modernization of traditional lattices. In particular, standards are set and proposed to identify different nations's lattices mainly focusing on grid type lattices which are often used and confusing.

The purpose of this study is to advance apartment houses in quality as a residence through revitalization of tradition and the procedures are as follows: The first procedure is theoretical contemplation. The second procedure is analysis of the traditional residential space that gives a starting point of introspection of it without cease at the stage of formal following or pattern application in revitalizing tradition in the apartment houses. And the third procedure is to select and suggest aspects applicable to developing Korean style apartment houses. The suggest is embodied by a plane figure of 55 pyong type apartment house after selecting the concrete development aspects with approaches such as arrangement and interior space analysis, behavior analysis and space division and design analysis. This study has its meaning in that it suggests a possibility of various approaches other than formal following or pattern application in revitalizing tradition in a new Korean type apartment house, that it gives another selection to diversifying consumers' patterns and that it helps recognize and develop our tradition in this age of cultural nationalism.

Master and slave of teleoperation control system through internet or long distance cable must keep stable. If one part becomes unstable or time delay happens in network, the all system can become unstable. Usually stability of teleoperation control system can distinguish by passivity. In this paper, we implemented bilateral teleopcration control system that load passivity controller to keep stability of system. Composed by manipulator that trillion this sricks and horizontal manufacturing that have force reflecting function are available and embodied so that control through wireless LAN may be available. And distinguished stability through an experiment and manufacturing performance.

Recently Fiber-optic Micro-cellular Wireless Network is considered to solve frequent handoffs and local traffic unbalance in microcellular systems. In this system, central station which is connected to several microcells by optical fiber manages the channels. We propose an efficient sectorization algorithm which dynamically clusters the microcells to minimize the blocked and handoff calls and to balance the traffic loads in each cell. The problem is formulated as an integer linear programming. The objective is to minimize the blocked and handoff calls. To solve this real time sectorization problem the Tabu Search is considered. In the tabu search intensification by Swap and Delete-then-Add (DTA) moves is implemented by short-term memory embodied by two tabu lists. Diversification is considered to investigate proper microcells to change their sectors. Computational results show that the proposed algorithm is highly effective. The solution is almost near the optimal solution and the computation time of the search is considerably reduced compared to the optimal procedure.

인터넷 사용의 증가와 함께 점점 확대되는 인트라넷 및 익스트라넷 환경에서 사용자 인증 과정은 필수적인 요소이다. 이런 환경에서의 인증 과정에 있어 현재 사용자 편의와 보안을 위한 단일 인증 시스템이 널리 사용되고 있다. 본 논문에서는 단일 인증 시스템에서 사용되는 인증 기법을 사용자의 신원을 증명할 수 있는 매체(증거물:witness)에 따라 사용자가 아는 정보(something known by user), 사용자가 소유한 정보(something possessed) 그리고 사용자가 지니고 있는 정보(something embodied)로 분류하고 또한 인증 기법의 보안 강도에 따라 약한 인증(weak authentication) 기법과 강한 인증(strong authentication) 기법으로 나누어 분석한다. 인증 모델의 분석은 우선 단일 인증 시스템과 유사한 몇 개의 인증 모델을 먼저 분석하고 그 다음에 인증 시스템의 적용 환경, 인증 시스템의 인증 위치 그리고 인증 모델이 포함되는 시스템 계층에 따라 인증 모델을 분류한 후 각 인증 모델의 특징에 대하여 분석한다.
