The usage of fixed call services and public payphones decreased due to the mobile services became general communications tools and the new VoIP services are emerging. Public phone services are included in the scope of universal services and the prices of services is low and the services are easy to access anywhere. However the telecommunication markets are changed then the loss of public payphone services gets worse and the importance of public payphone have decreased. This paper reviewed the universal services regulations of public payphones in overseas countries and proposed the implications of improving the universal service regulations for public payphones.

This study compares choice of contents genre between mobile VOD service users and landline internet VOD service users. Overall, males showed a higher rate of VOD usage than females and a variety of contents were used for entertainment, programs and mood alteration. In addition, a higher frequency of VOD usage showed a higher rate of VOD usage and also resulted in higher level of satisfaction. Also, the quality of landline internet VOD service showed to be higher than mobile VOD service. This suggests that programs for mobile VOD needs to be developed as well as a more open and simple rate system. In addition, subjects of this study showed to use VOD services mainly for entertainment purposes, suggesting that a variety of programs need to be developed in order to higher the level of satisfaction of its users.

MVNO(Mobile Virtual Network Operator) promotes service competition in mobile telecommunication market and provides various service and opportunities for consumers. This study attempts to identify MVNO Service users' motivational and dissatisfying factors in relation to their willingness for continued use of the service 새 activate MVNO service. Use motivation factors are found as customer service, user interface, easiness, economical efficiency, and dissatisfying factors are handset quality, customer service, social influence. Economic efficiency factor had an affirmative influence on the sustained use motivation of the service users. Among dissatisfying factors, users had a negative influence when they recognize that their neighboring people does not use MVNO service. Policy authorities concerned must excavate a new plan to improve distribution structure of handset and reduce wholesaling cost of the MVNO service. It is necessary for MVNO service provider to develop a new business model so that users can recognize MVNO service not as inferior service but as rational and attractive service.

The purpose of this study is to explore factors that influence the use of intercity-bus services by means of applying a structural equation model. The data were collected by a questionnaire survey based on personal interviews with intercity-bus users in Chungcheongnam-do province. Analysis results show that environmental attributes of the bus service are more important than operational attributes. In the case of men, the cleanliness of bus stops and the ease of transportation card recharging are likely to be the most crucial factors. However, women are likely to consider the cleanliness of the bus as the most important factor affecting their satisfaction about the intercity-bus service. Moreover, as people's satisfaction about the bus service increases, their willingness to recommend the use of intercity-bus to others will increase. Therefore, to improve the use of intercity-bus and to increase the satisfaction about the service, clean buses must be provided. These results could contribute to developing a policy to activate the use of intercity-bus.

D-CATV VOD service provides various contents such as drama and movie with high quality regardless of time and place. As the usage time of the VOD service increases, the viewing time of real-time terrestrial broadcasting is shortened. As the demand for VOD service is high and the number of digital users is increasing, the VOD market is rapidly growing. Therefore this study investigates the age and gender analysis of digital cable TV users and analyzed the usage patterns and audience cases of users. VOD service has been shown to be used by many users for the first time through remote control and free coupons. Non-users of VOD service did not use it because of charge and did not feel the necessity, but some non-users did not recognize the free VOD service.

Recently, developing information technology and increasing internet usage, e-Learning service industry is rapidly growing. However institutions and regulations related e-Learning service are insufficient. Users of e-Learning service were lower grade in school relatively, spent average 40,000won/month and used other private education service. Users answered that they were generally satisfied at e-Learning service but were not satisfied at e-Learning 'fee'and 'the contract process'. Specially, the result suggest that consumer's satisfaction is affect by experience of demage and complains related e-Learning usage.

The purpose of the study is to suggest and measure the ways to activate the use of wireless internet services in university libraries. For this, 1 reviewed the concepts and characteristics of wireless internet and investigated both local and foreign cases on wireless internet service of university libraries, library users' usage status, and their demands. Based on the case study and survey results, I suggest the strategic consideration and active publicity of university libraries, the introduction of the services students more prefer, the development of differentiated menus from ordinary wire internet services, and the consistent financial support of the university authority.

현재 인터넷 서비스는 이용자의 증가와 멀티미디어화의 추세에 따라 고속의 정보이동 및 접속속도가 요구됨으로써 인터넷 고속접속을 위한 해결방법에 대한 관심이 높아지고 있다. 또한 많은 선진국들은 국가경쟁력 강화 차원에서 인터넷에 많은 관심과 노력을 기울이고 있으며 우리 나라도 1999년 3월 정보통신부에서 발표한 Cyber Korea 21에 따르면 2001년까지 인터넷인구를 1,000만 명으로 확대하며, 2002년까지 현재보다 100배 빠른 인터넷을 구현하는 것으로 목표설정을 하고 있다. 따라서 본 고는 국가경쟁력 확보 차원에서 초고속 인터넷 접속기술들과 서비스를 살펴보고, 2002년까지 전국 어디서나, 누구든지 쾌적하고 저렴한 요금으로 초고속 인터넷 서비스를 이용할 수 있는 효율적인 초고속 인터넷 대안을 분석하였다. 결론적으로 현재까지 모든 조건을 충족시키는 완벽한 초고속 인터넷 접속기술이 존재하지 않으나 경제적 효율성, 기술적 안정성, 향후 시장 전개 등을 고려할 때 2001년까지는 ISDN이 효율적인 대안으로 제시될 수 있을 것이다.

모바일 인터넷 시장의 양적성장에도 불구하고 사용자들은 모바일 인터넷 서비스를 이용하지 않거나 지속적으로 이용하지 않는 것으로 나타났다. 최근 모바일 인터넷 서비스 시장은 요금인하와 풀브라우저의 보급으로 모바일 웹2.0 서비스의 이용자가 증가할 것으로 예측되고, 모바일 비즈니스는 다양한 측면에서 e-비즈니스를 능가하는 영향력을 행사할 것이며, 실시간 인터랙션으로 개인과 기업의 생활과 방식을 변화시킬 것으로 예상된다. 본 연구에서는 분해된 계획행위이론을 연구의 기반으로 하여, 새로운 모바일 웹 서비스의 수용에 영향을 미치는 주요한 요인을 찾고자 한다. 본 연구는 모바일 웹 2.0 서비스의 사용의도에 영향을 미치는 요인을 적합한 모형으로 검증함으로써, 모바일 비즈니스를 수행하고자 하는 기업에게 사용자의 행위에 대한 이해의 폭을 넓히고, 향후 이 분야의 기초자료가 될 것으로 사료된다 연구결과에 대한 이론적 해석과 실무적 시사점이 제공된다.

전기통신사업법상 이동전화사업자의 단말기보조금 지급금지 그 자체는 경쟁원리에 부합하지 않는다. 단말기 보조금의 금지를 정당화하는 유일한 근거는 그것이 갖는 비대칭적 성격이나, 그로 인하여 유효경쟁이 촉진될지는 확실치 않다. 이동전화시장에서 사업자 전환에는 요금이나 통화품질보다 이용자의 전환비용이 매우 큰 영향을 미치며, 따라서 전환비용을 낮추는 것에 초점을 맞출 필요가 있다. 그렇다면 번호이동성을 통하여 충분히 제거되지 않는 고착효과 및 전환비용을 가능한 해소하기 위해서는 지금과 같이 엄격하고도 일률적인 단말기보조금 금지는 재고할 필요가 있다. 여기서 유의할 것은 경쟁적인 보조금 지급이 후발사업자의 존속을 위태롭게 할 수 있다는 점에서 통신시장에서 어느 정도 유효경쟁체제가 자리잡은 이후에야 보조금 지급을 완전히 허용할 수 있다는 점이다. 다만, 비대칭규제의 취지는 어디까지나 이미 쏠림현상으로 고착화된 독점적 시장구조를 유효경쟁체제로 전화하는 데에 있다는 점에서 볼 때, 어느 시점에서 단말기 보조금을 허용할 것인지는 현재 또는 향후의 시장 상황에 대한 면밀한 분석을 요한다.
