In this paper, we proposed the multiple access control of RS232C Serial Communications protocol using collision sense method. The communications wires of data transmission and reception are tied together through the buffer each to connect to the multiple communication channels. The hardware interface and control program are designed to build the prototype system and the experimental multiple access communications network is built by multiple PC systems and the transfer completion rate results are shown.

This paper has been studied a interworking signalling protocol between two hybrid networks by analyzing Satellite B-ISDN architecture, DSS2 Layer 3 Signalling protocol B-ISUP protocol, S-BISUP protocol stack and so on. Also in the paper, messages and primitives have been defined for B-ISDN's Connection Type, Ownership and each protocol in order to connect point-to-multipoint. And then this paper has designed basic call procedures for OBP Satellite B-ISDN NNI inter-working protocol, verified and implemented them.

In nonlinear control fields, for irregular nonlinear systems, control form which consists of approximate tracking control law and exact tracking control law and which switches between two laws has been proposed recently. In this thesis, we design new switching control law which connect approximate linearization control law and exact linearization control law by fuzzy rules for irregular nonlinear system, ball and beam system. Fuzzy switching controller designed by fuzzy concept is proved that designed scheme overcomes singularities of irregular system, improves unstability problem of switching procedure, and has more efficient control value through simulation. Stability of fuzzy control system proved by Lyapunov's stability theorems.

In this paper, methods to analyze wire sweep during the semiconductor chip encapsulation have been studied. The wire sweep analysis is used to analyze the deformation of bonding wires that connect the chip to the leadframe during encapsulation. The analysis is done using either analytical solutions or numerical simulation. The analytical solution is used for rough but fast calculation of wire sweep. The results from the numerical simulation are closest to the experimental results.

Because of three reasons: rare natural resources, high dependent ratio and rapid wage increases, Korea must take the non-price competitive strategy. The developing process of quality management system in Korea can be categorized into five stages according to changes in economic policy. In order to develop the Korean quality management system effectively, we should try to connect total quality management with management system and emphasize the training and education.

The aim of this study is to develop a strategy for building healthy schools. For this, the concept of a healthy school was defined and the need for healthy schools was identified and reviewed. This included comparative studies of foreign countries as well. This study found that the elements of a healthy school were physical, psychological, environmental, nutritional, educational, serviceable, and practical. The strategy of building this model was to connect students and teachers, school and administration, and parents and community within one circle on the basis of these elements.

본 논문에서는 멀티미디어 어플리케이션의 핵심인 오디오나 비디오와 같은 연속 미디어에서 hiccup의 발생을 최소화시키기 위한 기존의 연속적인 재생, 재생 요구 이동, 복제, N 버퍼링 기술들의 단점을 보완한 완전 연결 버퍼링 알고리즘을 제안하였다. 제안한 알고리즘은 기존의 재생 요구 이동 기술에서 불균형적인 재생 요구 분포에 따라 야기되는 지연 시간을 최소화시키기 위해 그룹, 버퍼, 디스크 사이에 완전 연결을 통하여 하나의 재생 요구에 대해 전체 디스크를 검색할 수 있는 특징이 있다. 향후 제안된 알고리즘은 구체적인 통계적 모델을 제시하여 다양만 재생 요구의 빈도 수에 따른 검증이 필요하다.

As Unix based server including Linux are increased steadily, MS group users who want to connect these servers are increased. There were lots of connection using traditional network services like telnet or ftp for a long while, but connection using "TTSSH or PuTTY" which get used free have been increasing since “secure shell”(SSH) appeared. This paper compare TTSSH ＆ PuTTY′s characters and using method, and propose remote-access tool which improve TTSSH for MS group users.

We have studied the methods to connect homes with a digital network and apply home automation to education. We presented the possibility of integrated education where public education at school can be extended to home. The hardwares related with home automation are continuously in development. We have demonstrated the materials appropriate for the levels of individual students with home network information, and studied methods of education.
