Mobile web browsing services that bring the full PC browsing experience to customer's mobile handset have been emerged. This study is to investigate the intention to use mobile web browsing based on Technology Acceptance Model(TAM) which has been widely used to explain and predict the IT acceptance and incorporated with self-efficacy which was identified as an important determinant of user's new technology adoption in recent literature on technology acceptance. Specifically, from a theoretical perspective, this study not only clarifies mobile self-efficacy, but also develops an instrument to measure the concept of mobile self-efficacy. The results indicate that both computer self-efficacy and mobile self-efficacy directly influence perceived ease of use, and that perceived ease of use enhance perceived usefulness. And the findings indicate that perceived ease of use and usefulness have direct effects on attitude and then it is positively associated with intention to use mobile web browsing. Therefore, the findings imply that mobile self-efficacy can be employed as an important variable in examining user's intention for various mobile services to come in future.■ keyword :|Mobile Web Browsing|Technology Acceptance Model|Self-efficacy|Mobile Self-efficacy|

Linking between a virtual space and a physical space, ubiquitous computing is expected to create new business value. So far, however, there is no broadly accepted methodology to develop the services based on ubiquitous computing technology. Hence, this study aims to seek a systematic methodology for developing new services based on the concept of business model and to apply this in the areas of waste management practices. In addition, based on the evaluation of u-business services in waste management domain, killer services were selected, and then linked with the latest ubiquitous computing technologies. The results of this study are to be applicable to an environment friendly ubiquitous service model of u-City.
