A number of Internet application services are used with the development of Internet backbone nowadays. Well-known services such as WWW, ]n, email are provided at first time. Tremendous unwell-known services are presented according to the demands of various contents. After analyzing PDU information of the packet using unwell-known port travelling on the internet, searching internet service type and its statistical data is provided with internet traffic analyst as very useful information. This paper presents the mechanism to extract the internet application services operated on (un)well-known port of UDP or TCP used occasionally through netflow and tcpdump method introduced by ethereal and the operation scheme of the service. Afterwards to get the detailed statistics of the analyzed application service, the agent and the server environment, the agent gathering raw data traffics and the server adapting the traffic received from the agent BNF(Backus-Naur Form) method, is also introduced. Adapting the presented mechanism eve. LAN of Andong national university, the internet traffic service type and the detailed statistics of the analyzed application services which provides with internet traffic analyst are presented as very useful information.

Despite young age, Internet, as new advertising media, is actively studied worldwide. In 1995, the department of multimedia-related study was first founded in Technical Institute and has carried out the On Internet banner, user is not an object to accept only a message but has a specification to contact with banner actively having various motivation and desire. Internet advertising has various types but banner and e-mail type advertising are main stream. In the view point of recognition and concern rate, banner is very effective because it does not set limit to specific target, but is shown to unspecific audience. Acceding to studies, usage frequency and effect of e-mail type advertising is growing up. And e-mail type advertising is more active because it can target specific audience with various life style. If we can say banner is not so effective in spite of simply good exposure frequency, we can find theoritical background that e-mail type advertising is more effective internet advertising media because high click frequency. And we suppose that this study can be a guide line for measuring process of Internet advertising effect.

신제품 개발은 기업의 흥망을 좌우할 수 있는 프로젝트이므로 공격적이고 적극적인 신제품 개발/컨셉 조사를 통해 진입시장의 특정을 정확히 파악해야만 효과적인 신제품 개발/컨셉 전략을 수립할 수 있다. 하지만 설문조사 방법을 수행하는데 있어서 많은 비용과 시간이 소요된다. 이 때문에 최근 인터넷을 이용한 설문조사 방법이 널리 보편화되고 있다. 인터넷 또는 이메일을 이용한 설문조사 방법은 전통적인 조사방법에 비해 여러 가지 장점을 가지고 있다. 이에 본 연구는 인터넷을 이용한 조사방법의 이론적 고찰을 체계적으로 정리하고 한 단계 진화하여, 최근 급속히 증가하고 있는 무선인터넷 기술을 이용한 설문조사가 가능한 시스템을 개발함으로써, 응답자는 자신이 가지고 있는 무선인터넷 단말기 (휴대폰, PDA) 를 이용해 조사에 응답하고, 조사자는 쉽고 편리하고 빠르게 정확한 데이터를 수집할 수 있는 기회를 제공하는 시스템 개발에 본 연구의 목적이 있다.

We live in the information technology era and experience the rapid global information environment change through Internet. Therefore, as distribution channels and service qualities in our daily lives are provided through Internet, these changes have been the foundation of constructing a new society. Naturally, the use of computer is widely spread out and it is hard to find any company that doesn't use computer in its work. However, the computer skills of those who are in their fifties cannot reach to what the companies need for them even though they are main working groups in our society. In addition, the Internet access rate of homemakers in their late forties and over fifties are low due to their lack of computer knowledge even though they are the target customers of the Internet service. Under these circumstances, we offer a lecture using simulation techniqe through which anybody can easily follow the instructions via the "Help" menu not a boring lecture that just show the text and reads it. Besides, each class will show you how to start Internet/ how to finish it, how to register a website, how to use e-mail, etc. So, it will let you know every detailed aspect that average people may disregard but a beginner may be afraid of starting the Internet.

기업과 기업간, 사람과 사람사이에 의견을 주고 받기 위한 매체가 다양화되고 있다. 방문이나 우편 등에 의한 의사 교환에서 전화, 이메일을 거쳐 메신저가 등장해 실시간으로 의견을 주고 파일 전송을 하고 있다. 메신저는 1:1문자 대화에서 1:다수의 형태로 진화되더니 급기야는 서로의 얼굴을 보고, 음성을 들으며 웹사이트, 문서 등을 공유하면서 회의를 진행할 수 있게 됐다.

These days, mobile technology is developing very fast. It has increased the usage of the Internet by mobile phones. Nowadays the avatar and game contents services are most popular in mobile phones using the Internet. In this paper, we propose a Client/Server system to combine the animation avatar and e-mail services on SK-VM which are different from simple avatar services. The server which consists of DB (database) module and mail management module is designed in order to manage the information about avatar and the user. The client is designed so as to show the email contents and avatar animation on the mobile phone. This model is intended to reduce the performance overhead on the client as much as possible. We expect that this module would be useful in the mobile phones with limited resources, although the technology is being developed very rapidly.

The messages on mobile terminal may contain context information such as user's location, time and preference. This paper proposes message forwarding system based on user's context. The server stores the predefined target addresses which may be mobile phone number, web server address and email address. On request for message transmission, the server tries to find a target address matching a user's context. Thus, a sender transmits messages to a representative address without knowing various receiver's addresses and a receiver can retrieve classified messages according to subject/location.

Domain Name System(DNS), one of the most important Internet services, handles mapping from host names to Internet addresses and vice versa, and precedes many Internet applications such as Web, e-mail, file transfer, etc. In this paper, we propose a structural design of a generic name server system providing name services for a huge domain for the purpose of improving the performance as well as the reliability of the system. We demonstrate the validity of the design by implementing and running a testbed system. Our testbed employs a couple of master name sowers for distributing the service overhead over two, rather than one, servers and for achieving high availability of the system as a whole. We suggest the use of dynamic update to add and delete records from a zone for which the name server has authority. The slave name servers located remotely then get a new, updated copy of the zone via incremental zone transfers(IXFRs). The experiments with the implemented testbed show that the proposed structure would easily manage increasing demands on the server power, and be highly available in the face of transient faults of a module in the system.
