With the rapid advance of internet service and the corresponding migration of service environment from the text-based one to WWW (World Wide Web) environment, the number of internet users is growing rapidly due to its easy usage. Accordingly, usage of internet as services for sending electronic mails to the other party over the network is becoming increasingly prevalent. Web-based electronic mailing system is comprised of a server and a client. The former provides the users with e-mail accounts and services, while the latter serves as a user interface. In other words, it enables those public users who dos not own e-mail accounts on the existing mail server to have an access to the mailing service through the web. In this paper, we designed a effective web-based electronic mailing system which is based on the internet explorer and linux operating system, which overcomes limitations of the existing e-mail systems and meets the need of a cost-efficient alternative. Our electronic mailing system also supports the convenience of users through appropriate handling of preregistered spam e-mails and multiple e-mails, and this facilitates the development of a stable e-mail system by being able to avoiding the low system performance due to the bursty characteristics of e-mail messages and the increasing number of users

The "information roadway" will give us an impact of new PC based assignments and administrations, yet the unusualness of this new condition will ask for another style of human-PC association, where the PC transforms into a sharp, dynamic and customized partner. Interface administrators are PC programs that use Artificial Intelligence frameworks to give dynamic help to a customer with PC based errands. Operators drastically change the present client encounter, through the similitude that a specialist can go about as an individual collaborator. The operator procures its capability by gaining from the client and from specialists helping different clients. A couple of model administrators have been gathered using this methodology, including authorities that give customized help with meeting planning, electronic mail taking care of, Smart Personal Assistant and choice of diversion. Operators help clients in a scope of various ways: they perform assignments for the client's sake; they can prepare or educate the client, they enable diverse clients to work together and they screen occasions and methods.

계약이나 송금 등을 행하는 서비스에서 서명은 없어서는 안되는 중요한 요소이며 특히 전자 우편(electronic mail), MHS(Message Handling System)나 EDI(Electronic Data Interchange) 서비스는 기업체는 물론 일반 사용자에게까지 널리 이용될 것으로 사료된다. 이러한 서비스의 특징은 통신망상에서 메시지를 이용하여 다양한 형태의 서비스를 제공하기 때문에 메시지 자체에 대한 인증이나 송신자, 수신자 상호 쌍방간에 인증, 부인 봉쇄 기능을 갖추는 것은 분쟁을 해결하는 필수 불가결한 요소이다. 이를 위한 기술적 대책이 디지틀 서명이다. 디지틀 서명 기술은 기존의 종이 문서에서 사용되는 수서명을 대신할 수 있는 것으로 메시지의 출처와 메시지의 진위 여부를 확인할 수 있는 매우 유용한 서명 방식이다. 그러나, 사실상 디지틀 서명이 많은 응용 업무에서 활용될 것은 자명한 사실이므로 적용 환경 및 적용 업무에 따라서 여러 가지 추가적인 요구조건이 등장할 수 있다. 이러한 특수한 디지틀 서명 프로토콜에 관한 연구는 매우 가치 있는 연구 분야이다.

This research presents development of real-time service primitive in MHS(Message Hanling system) supporting desk-top conferencing system. Desk-top conferencing system is one of the real-time GC(Group Communication) services. The complexity of modem society has led to the consequent need for real-time GC between a number of people in order to jointly handle tasks in business, government and other forms of organization. Despite the many different form of desk-top conferencing systems developed to date, there are still few systems in widespred no. One of the biggest hurdle preventing the widespred adoption of real-time GC is the lack of agreement on user-friendly interchange environments. In distributed office environments, the MHS is one of the most widely used service for information interchange. It is a standard of electronic mail system which is concerned mostly with asynchronous exchange of short notes. It is clear that additional functions on MHS are necessary in order to allow users to properly process their real-time group messages and provide them with important facilities as a communication infrastructure for real-time GC.
