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.

This study investigated the structural relationships among factors on intention to use mobile learning and suggests practical strategies to enhance learners' behavior intention in secondary school. In this study, we hypothesized that mobile computing self-efficacy, personal innovativeness, and social influence had positive effects on perceived usefulness and perceived ease of use, which ultimately had positive effects on intention to use mobile learning. In order to examine structural relationship among variables, we surveyed 289 high school students in spring semester of 2014. After collecting data, we examined causal relationship among variables using Structural Equation Modeling. The results of this study are as follows: First, mobile computing self-efficacy and personal innovativeness significantly affected perceived ease of use. Second, mobile computing self-efficacy, social influence, and perceived ease of use significantly affected perceived usefulness. Lastly, perceived usefulness and perceived ease of use significantly affected intention to use mobile learning of high school students.

The purpose of this study is to examine a structural relationship among mobile self-efficacy, subjective norm, perceived usefulness, perceived ease of use and behavioral intention of mobile web service using technology acceptance model (TAM). 144 cyber university students enrolled in a course with mobile web service participated for this study. The result revealed that 1) mobile self-efficacy (${\beta}$ = .43, p<.05), subjective norm (${\beta}$ = .30, p<.05), perceived ease of use (${\beta}$ = .25, p<.05) had a direct effect on perceived usefulness. Second, mobile self-efficacy (${\beta}$ = .36, p<.05), subjective norm (${\beta}$ = .44, p<.05) had a direct effect on perceived ease of use. Third, perceived usefulness (${\beta}$ = .94, p<.05) had a direct effect on behavioral intention of mobile web service. However, perceived ease of use did not have a direct effect on behavioral intention of mobile web service significantly. Results of this study emphasize the role of an extended TAM including mobile self-efficacy and subjective norm in a mobile web service course at a cyber university.

Mobile healthcare apps should be paid more attention not just as software, but also as significant health information providers. We examine the impact of psychological factors (e,g., instrumental efficacy, informational efficacy, health information orientation, playfulness, and responsiveness) on intention to continuous use of mobile healthcare apps. Based on an expanded technology acceptance model (TAM II), this study examined the effects of psychological factors influencing the usage of mobile healthcare apps. The results showed that informational efficacy and instrumental efficacy influenced intention to use through perceived ease of use and perceived usefulness. Playfulness influenced intention to continuous use directly as well as indirectly through perceived ease of use and perceived usefulness. Health information orientation and responsiveness influenced intention to continuous use through perceived usefulness. This study suggests the need for adopting instrumental, informative perspectives and playfulness in contemporary health research and production of mobile healthcare apps.

This study aims to determine the factors affecting people's intention to use mobile delivery application services. The technology acceptance model (TAM) was employed and a survey was conducted on 300 delivery application users. As a result, personal innovativeness was found to have a positive effect on perceived ease of use and perceived playfulness. Self-efficacy turned out to have a positive influence on perceived ease of use and perceived playfulness. Next, perceived ease of use was found to positively affect both perceived usefulness and perceived playfulness, and perceived usefulness and playfulness had a positive effect on the intention to use the service as well. Lastly, personal innovativeness and self-efficacy were found to have a significant indirect influence on the intention to use the service. This study suggests users can be induced to voluntarily and continuously use the service, if their personal characteristics and perception of the service are considered in the future development of the service.

This study empirically studied the factors affecting the intensity of use of mobile social media and fatigue. Theories for the research framework were based on the theory of planned behavior, the theory of private information protection, the theory of flow, and the theory of process incentives. As a result of data analysis, it was found that self-efficacy, user habits, and flow experience positively influence the intensity of mobile social media use. This study assumed that personal information protection issues negatively affect the intensity of mobile social media use, but have little influence on the use intensity. The intensity of media use had a positive effect on media fatigue. In other words, when the intensity of using mobile social media increased, the feeling of fatigue increased. The expected process incentives variable did not show a moderating effect between media use intensity and social media fatigue. The findings will have implications for social media-related companies and organizations that want to use social media tools for business and public services.
