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 interworking protocol, verified and implemented them.

A gauge-adjustable system can be used for the fast and safe transportation in the railways with different gauges instead of transshipment or bogie-changing. The system will be necessary to connect the trans-Korean railway with the transcontinental railway effectively. In this paper, the technical requirements for the gauge-adjustable system used for the north-east asia network were studied and the conceptual design of the system was performed. For the purpose, the specification was made and the QFD and TRIZ methods are used.

Korean Sign Language (KSL) is a communication method for the Deaf in Korea, and hand shape is one of important elements in sign language. In this paper, we developed a KSL hand shape editor to simply compose hand shape and connect it to a database. We can edit hand shape by a graphical user interface (GUI) on 3D virtual reality environment. Hand shape codes are connected to a sign word editor to synthesize sign motion and to decrease total amount of KSL data.

The purpose of this study is to suggest the direction for development of function materials integrating mathematics and science. First, we must investigate curricular scope and sequence of mathematics and science. Second, the science contexts selected need to support the mathematics concepts, not overwhelm them. The mathematics can easily get lost if science becomes too complicated. We may be tempted, which can result in misconceptions that are hard to correct later. Third, Many different examples of mathematics-science integration exist, therefore, it is important to find rich science contexts to connect with mathematics.

The purpose of the study is to introduce how elementary mathematics pre-sevice teachers in pre-service teacher program could use and integrate poster, a kind of instructional media, to connect mathematics knowledge to real worlds. Poster examples include such as connection to mathematicians and mathematical connections to real world as well as nature. Further, future study will continue to foster students and teachers to try to construct their alive mathematics knowledge.

An e-catalog system provides whole product data and services by publishing newly updated information that connects PDM systems in an enterprise. With its capability to connect customers, suppliers, producers, distributors and downstream manufacturing activities, the e-catalog system can be applied to integrate e-business and provide immense business opportunities. In this paper we propose a framework focusing on constructing an efficient e-catalog system that can be used for online mass customization. The effectiveness of the proposed framework is validated with experimental results.

In this study, I consider Brousseau's theory of didactical situation focused on 'the development process of situations', and analyze some examples of didactical situation related to instruction of 'decimal' concept. To elaborate situations which really make a mathematical notion function, we have to analyze the essence of the notion, and to construct the situation which can be developed to situations of 'action-formulation-validation - institutionalization'. From this view, it can be said that the instruction of decimal concept in our country mainly lies in the situations of 'action' and 'institutionalization'. we have to provide more situations of 'formulation' and 'institutionalization' which can connect 'action' and 'institutionalization'.

웹 서버에서의 서비스 품질을 지원하기 위하여 Web QoS를 보장하는 계층을 서버에 추가하는 방법에 대한 연구가 이루어지고 있다. 그러나 기존의 방법은 웹 서버의 자원을 소비하며, QoS를 보장하도록 웹 서버를 수정하여야 하는 단점이 있다. 본 논문에서는 기존의 웹 서버를 그대로 이용하면서 이러한 단점들을 보완하는 웹 서비스 연결 요청을 조정하는 별도의 커넥션 매니저를 설계하고 구현하여 웹 QoS에 대한 효용성을 점검 하였다.
