인터넷의 확산과 All-IP망으로의 망의 진화에 대한 논의가 활발하게 이루어지고 있다. 더불어 IPv6[1]망에서의 이동성 지원을 위하여 IETF(Internet Engineering Task Force)에서 Mobile IPv6를 제안하였다. Mobile IPv6[5]의 기본 발상은 Routing Table의 변경에 의에 다른 링크로 이동한 호스트에게 Packet를 전달할 수 있게 하는 것이다. (Triangle Routing[4]). Mobile IPv6을 구성하는 요소 중 Mobile Node의 기본 구조를 제시했다. Mobile Node 자신의 위치 정보를 갱신하는 Move Detection이 핵심적인 부분이다. 본 논문에서는 이 절차에 대한 보다 실제적인 고찰과 이를 의한 설계를 제시한다.

In this paper we consider an age dependent branching process whose particles move according to a Markov process with continuous state space. The Markov process is assumed to the stationary with independent increments and positive recurrent. We find some sufficient conditions for he Markov motion process such that the empirical distribution of the positions converges to the limiting distribution of the motion process.

In this study, the author uses a MATLAB simulation to develop and test a generalization of the traditional Random Search model which allows both the searcher and target to move and to be in different, but overlapping, areas. Also the best evasion speed for a randomly moving target against a Systematic Search is studied.

A solution of the findpath problem in which a moving object in required to avoid moving obstacles and move to the designated target in the plane is porcided via the second method of Lyapunov. This paper presents an new control designed by a family of piecewise Lyapunov functions to solve a findpath problem and gives some simultion results of that.

Although student-centered teaching practices have been advocated in mathematics education reform, implementing them at the classroom level remains challenging. This exploratory case study examined two unevenly successful student-centered approaches to see how teachers understand and characterize reform, and to articulate issues in implementing reform ideas. The comparison and contrast between the classrooms showed similar classroom social norms but dramatically different mathematical practices. This affords the possibility of exploring the challenges of reform for teachers and other personnel who are attempting to move teaching practices towards the student-centered ideals.

The authors observed thee life history of Cyrtarachne inaequalis Thorell, 1895, during from September 21th, 2001 to April 17th, 2002. Cyrtarachne inaequalis Thorell, 1895 are distributed in oriental region including Korea, China, Japan, India, and Taiwan. The eggs were hatched out from March 31th, 2002 to April 1st, 2002. Cyrtarachne inaequalis Thorell, 1895 usually began to move after sunset. The structure of web was irregular. This study shoos the ecological Life of Cyrtarachne inaequalis Thorell, 1895.

Let G be a connected graph. A pebbling move on a graph G is taking two pebbles off one vertex and placing one of them on an adjacent vertex. The pebbling number of a connected graph G, f(G), is the least n such that any distribution of n pebbles on the vertices of G allows one pebble to be moved to any specified, but arbitrary vertex by a sequence of pebbling moves. In this paper, the pebbling numbers of the lexicographic products of some graphs are computed.

In a very time, the Internet has affected the lives of millions of peoples. Some serious advances have been made in software development, information exchange, publishing, database retrieval, educational opportunities, commercial expansion, political awareness, and more. But this network of network is still in its infancy. More advanced search concept, World Wide Web(or Web) will continue to help users move boldly onto the information highway. It help user work effectively and efficiently. In this article, we explain how to utilize web to enhance research in Industrial Engineering area.

Hypermedia systems allow the retrieval and representation of multimedia in- formation such as text, graphics, image and voice/sound using navigation and browsing mechanisms. In this study we developed a hypermedia system which provides hierarchical group, local map and cluster view for effective navigation in hyperspace. The system also supports hot link, reference link, move-to link and multiple link to browse the multimedia information space effectively. This system has been designed to integrate the navigation, browsing and searching function of the hypermedia system in hyman factor perspective and provides the user-friendly user interface mechanism.
