This study aims to identify the factors that influence adoption intentions towards portable Internet service, based on the individual characteristics that assist in creating markets and developing strategies. Two types of factors are defined: individual characteristics including demographics, existing services usages, prior knowledge, adoption attitudes, and service evaluations; and adoption intentions including the willingness to subscribe, subscription term, willingness to pay, usage type, and preferred terminal. The results indicate that the importance of demographic variables depends on adoption intentions, and that users of mobile Internet service and wireless LAN are probably targets for portable Internet service. Furthermore, the results demonstrate the need for an enhanced perception of the usefulness and ease of use of service, as well as an intensive marketing activity for potential users and a bearable innovation to stimulate the market for portable Internet service.

The global mobile Internet service market is growing very rapidly, shooing drastic increases in its sales volume. Despite this growth of the market, it has not yet reached its full-grown stage, and this calls for a study on the service preference based on the characteristics of the users. As most of the existing studies in this area have centered on its technical features, they fall short of providing to the related companies any useful data to which they can practically refer in developing the future mobile services that suit for various user needs, and making plans to increase the sales volume. Based on these circumstances, this study is to investigate how the mobile contents preference is differed in accordance with the user characteristics of the Korean and Chinese mobile Internet service users. This study is also to analyze how the relationship between the user characteristics and the preferred mobile contents types is moderated by nations, Korea and Chinese. To accomplish these research purposes, this study developed a set of research model and hypotheses based on a comprehensive review of the related studies. To prove the research hypotheses, this study conducted a survey among the Korean and Chinese nubile Internet service users and performed a variety of analyses of the data collected including the questionnaires, using the SAS version 9.

The mobile internet telephony service rapidly grows according to the extending deployment of smartphones. Unlike telephony service over a conventional public switched telephone network (PSTN) or mobile network, internet telephony service cannot guarantee its service quality, which can be severer in a wireless environment. Therefore, a more strict and systematic quality management is required for successful settlement and popularization of mobile internet telephony service. Existing quality management scheme using a specific measurement equipment cannot measure all the time so that it performs late management. In order to overcome the problem, this paper develops a software that can be equipped on a user terminal and measures the service quality all the time. By using the developed software, all-time and user-activating service quality monitoring can be supported.

Also, the reserch result shows banks can reduce conventional branches while experiencing a positive implications on their profits from the customers. Another significant implication from the research is, to accelerate the shift to digital channels, banks need to put more efforts on developing functions in the mobile channel that will allow friendly interaction with customers and consultation, such as video consultation, interactive chat, and location-based product recommendation.

Mobile internet service based on CDMA network evolution and multifunction mobile terminal is popular in Korea. Mobile internet service is classified as the information service using browser and mobile multimedia service using download platform. Killer applications based on multifunction mobile terminals have been developed for new business in mobile internet services. One of killer applications is location based seurvice (LBS) using mobile location information. In this paper, we develop mobile map browser using WIPI platform that is the main function in LBS. Mobile map browser interworking with GIS server provides the map information. The developed mobile map browser can be working on PDA and telematics terminals when WIPI is porting on these devices.
