Mutimedia conference technology provides reference service as well as data service via Internet. Many standards and related applications were developed based on H.323 protocol. but H.323 protocol more complex than SIP. so IETF have developed standard that related conference control based on SIP. In this paper, we discuss REFER method that used for conference invtitation and ejection esign conference event package for conference system based on SIP protocol.

In order for all participants at video conference to communicate mutually, the conference key should be necessary. In this paper, we present the communication protocol that generates a conference key efficiently based on $(\upsilon,\kappa,\lambda)$-configuration, one class of block designs, which minimizes message transmission overhead needed for this key. Especially, in the case of ${\lambda}=1$, the protocol requires only $O(\sqrt[v]{v})$ messages, where v is the number of participants.

Recently, the conference is increase continuously, and the public relations and administration are increasing. Therefore, the many expense of small academic society and official overhead are generated for supporting the service of conference registration and announcement. Accordingly, in this paper, the building tool designs and implements for the registration and public relations of a small-scale conference on Internet. This tool supports an automatic building of a conference homepage and easily operation of the conference. And, the building tool provides the paper submission function, the pre-registration function and the email sending function using the conference homepage on Internet.

These day, market demanded to a Video conference systems rapidly increases in our life for cut cost in communication. more and more it will be grow up. but the cost building to a Voice conference and a Video conference is very hight. therefore it is builded around the big company and the public office. so in this study, we have developed to hybrid IP-PBX which is able to a Voice conference and a Video conference with one system. the system developed has the merits to low-price for it's building in a small company. we make proof the performance through the test. with using the hybrid IP-PBX, we can sharply reduce to communication cost.

Recent multimedia technology has supported various application services based on the development of effective movie compression and network techniques. On-line video conference system is a typical example that use theses two technologies effectively. On-line video conference system can be characterized into an effective conferencing method for long-distanced on-line conference members. But, unfortunately, off-line conference with face-to-face meeting is more frequent than on-line conference and their support systems have not been sufficiently considered. In this paper, we propose a recording support system for off-Line conference using face and speaker recognition. This system finds the speaker in the conference by using three microphones and three webcam cameras. And analysis is done with face region information that gathered by currently active webcam camera, and recognizes the identity of face. Finally, the system tracks speaker and records conference with extract speaker information.

일본은 TTC에 의해 제정된 표준을 기초로 하여 개발된 전기통신장비 또는 시스템의 상호접속성을 확인하기 위해, '고도 통신시스템 상호접속 추진회의(Promotion Conference of Harmonization of Advanced Telecommunication System: HATS Conference)' 를 설립하였다. HATS Conference에는 전기통신사업자, 표준화기관, 제조업자 등 여러 기관이 참여한 가운데, 상호접속성 대한 사용자의 요구사항과 기술적 문제를 다루기 위해 6개의 실무그룹과 디지털전화, 터미널 어댑터, 디지털 PBX, G4 팩스 등과 같은 장비 또는 시스템간의 실제적인 시험을 위해 상호 접속성 '시험구현연락회(Test Implementation Liaison Committee: TILC)' 가 구성.운영되고 있다. 따라서, 본 고는 HATS Conference가 주관하고 있는 전기통신장비 또는 시스템간의 상호접속성 시험체계를 분석한 것이다.

This paper is to review the conclusions of the Athens conference that has so far contributed to the conservation world. It is normally called the conclusions of the Athens conference as the Athens charter. But the conclusions of the Athens are not as same as the Athens Charter regarding the contents. The former had more valuable contents than the latter regarding historic monuments. And the report of the Athens conference including 56 articles and 500 pages with 55 photos was published in 1933 by the International Museums Office. But little attention has been given to the report of the Athens conference. Therefore the point I want to make is to review to the report in order to understand the agenda of the conference and to examine the Anastylosis in Acropolis. In conclusion, these agendas and the articles in the report show us that the conference was sort of milestone with some advanced modern philosophical and technical concepts about conservation and restoration of historic monuments. Also when the term of anastylosis turns to reconstruction in archaeological sites, we are going to face with the problems of authenticity.
