One of the main problems of today's ubiquitous computing systems is that they do not meet their quality requirements. Prior studies had investigated quality factors that were important to users regardless of use contexts. However, mobile computing services such as mobile data services (MDS) are fundamentally different from traditional information systems (IS) because it has been used in various life contexts. We conducted a qualitative study to identify important quality factors on various contexts in MDS. The results show that important quality factors in mobile computing services are differentiated from important quality factors in information systems.

This study analyzes factors that influence use diversity or usage of mobile video services. This study conducts multiple regression analysis to draw the major factors that affect use diversity or usage of mobile video services. The major findings of this study are as follows. First, IPTV membership status, DMB watching status, and TV contents broadcasting status affect the use diversity of mobile video services. Second, TV contents broadcasting status and video streaming quality affect the usage of mobile video services. This study provides some implications that TV contents broadcasting is a core element in mobile video services. The future research is discussed.

The purpose of this study is to investigate the effect of mobile payment service quality(system quality, service quality) on the formation of trust(cognitive trust, affective trust) and the effect of trust on satisfaction. In addition, we examined gender differences in the process of trust affecting satisfaction. The 188 sets of data collected, those were tested against the model using PLS. The results showed that system quality affected cognitive trust, service quality affected cognitive trust and affective trust, and both cognitive trust and emotional trust had an effect on satisfaction. In addition, the influence of cognitive trust on satisfaction was stronger for males, and affective trust had more influence on satisfaction for females.

The mobile commerce (m-commerce) has very high market value unlike other technology innovation areas in IT industries and also changing rapidly. Therefore, it is fact that the development of the effective business strategy is challenging in a digital convergence era of m-commerce context. In most of the researches, m-commerce has dealt with conceptual study such as establishment of definition. There are not many studies of influence of information valuation evaluation on users' satisfaction have done so far. In this paper, we have reported a theoretical study as well as empirical analysis and examined an influence of information valuation evaluation have on users' satisfaction. A questionnaire was constructed and data were collected from 192 users of m-commerce system. The results indicated that users' satisfaction was affected by information valuation evaluation and difference between cost satisfaction and service quality satisfaction according to users' specialty.

Using mobile bookstore application is increasing in accordance with the proliferation of internet and mobile devices. In this circumstances, the purpose of this study is to explore the factors regarding to mobile bookstore application quality evaluation are effecting to customer satisfaction and reuse intention. Thus information, transaction, design, communication, ubiquitous access, personalization, safety are set as a quality evaluation factor. And it is analyzed the effect of these factors to customer satisfaction and reuse intention with path analysis method. As the result, transaction, ubiquitous access, personalization, safety factors effected customer satisfaction and customer satisfaction effected reuse intention. These results show that user mainly access mobile bookstore application for purchasing book. Thus it is important for mobile bookstore operator to keep the application accessed anytime, and serve personalized information, and simplify transaction process, and intensify security for protecting personal or transaction information.

The purpose of this study is to identifies the effects of service quality factors on satisfaction and trust, and then verifies the causal relations among satisfaction, trust, commitment and using intention in mobile service setting. A survey was conducted to collect the data with consumers who had the actual using experience about mobile services. Analysis of structural equation modeling with SPSS 20.0 and AMOS 16.0 were performed to test the research hypothesis. The result of the study as follows: First, it was found to difference in relationship between dimensions of mobile service quality and satisfaction except for the pleasure. Second, the sociality was found to significant path coefficients in relationships with trust. Third, satisfaction and trust have influence on commitment and commitment has effects on using intention, but there had no significant path coefficients between satisfaction and trust, and then both satisfaction and trust were not found to significant path coefficients in relationship with using intention. Therefore, Marketers of mobile service corporate have to give excellent service quality to consumers who have using their mobile service for increase of using intention through build up trust and commitment by consumers who satisfied.
