This paper is addressed to Internet telephony based service implementation. It describes an implementation method which uses ARS as a gateway which combines Internet and traditional public switched telephone network for Internet information service using telephony and fax, is different to traditional Internet telephony which provide enhanced speech quality and low cost functionality. This method allows telephony and/or fax user to get Internet information without additional Internet bill, Internet infrastructure and low connection quality from low signal bandwidth connected him. Implemented system is useful to a special kind information service such as climate information of Korea etc and simpler than WAP based service as for wireless mobile telephony user. We implement job opportunity information and advertisement service supported by Home page of Choong Book Small & Medium Business Administration and e-mail service supported by Korean Society for Rehabilitation of persons with Disabilities to demonstrate the system ability. As a result of test implementation, this service system works good fur blind persons and graduated persons without job, is expected to apply for special Internet information provider via Voice and Fax.

With proliferation of the internet, the internet ethics in contrast to existing ethics has been recognized as one of the disciplines. Internet ethics is one of liberal arts courses in a college as well as a class in elementary, middle and high schools. We also have taught this subject for a number of years. In order to effectively communicate to students the internet ethics course as computer scientists, we gave some demonstration practice lectures by taking advantage of internet ethics related videos. Since the latest UCC presentation and its discussion were performed, it was helpful for students to recognize the internet ethical issues and concerns. We confirmed that classroom students' concentration and understanding for internet ethics increases by a survey of the regular attendees. This research presented a lecture practice case model to teach comprehensive internet ethics topics to college students effectively.

Since the Internet was applied for commercial purpose, many companies have been making use of the Internet in electronic commerce and the Internet has brought many changes on consumer and supplier behaviors. It seems that consumers and suppliers can obtain more accurate information rapidly and pay less for the same product/service than in traditional commerce. This study tries to investigate the difference in the cost factors perceived by consumers between traditional commerce and the Internet commerce. Empirical results show that there is no significant difference in consumers' perception of cost factors between traditional commerce and the Internet commerce. Contrary to general perception, a large number of consumers do not believe that the Internet commerce is generally more economical than traditional commerce. The factors where the consumers think Internet commerce has cost advantages are search cost and purchasing cost. However, consumers are understanding the benefits of the Internet commerce and are expecting that Internet commerce bring about economic advantages in consumer markets in the near future.

Fast spreading Internet worms, such as Code Red and Slammer, have become one of the new major throne of the Internet recently. In order to defend against theses worms, it is essential to understand how Internet worms propagate and how different Internet factors affect worm spreading. In this paper, we intend to describe the spread of worms on Internet environments accurately. Therefore we model and analyze the spreading effects by various simulations considering Internet addressing and speed. The results lead to a better prediction of the worm spreading on current and future Internet environments.
