The purpose of this study was to verify and analyze the factors that influence the acceptance intention of u-Commerce users under ubiquitous computing environments. To accomplish this, the Technology Acceptance Model(TAM) of Davis(1989), which has widely been cited in new technologies such as information technology(IT) and information systems(IS) studies was used to develop the research model. First of all, personal characteristics affecting the acceptance intention of u-Commerce were identified as individual variables through literature review. Utilizing the use of the individual variables and the TAM model, the u-Commerce acceptance intention model was established. The research findings indicated that IT acceptance forms and frequencies in IT use did not have a significant impact on perceived usefulness and perceived ease of use of u-Commerce. It was also found that the perceived usefulness proposed in the u-Commerce acceptance model influenced the perceived usefulness. Both ease of use and usefulness were identified to influence attitude for use. Finally, usefulness and attitude for use also positively influenced acceptance intention. The contribution of this study was the examination of the factors affecting acceptance intention of users in u-Commerce and the verification of the usefulness of the TAM model in describing the acceptance of u-Commerce users using structure acceptance model. Furthermore, this study has empirically analyzed how personal characteristics widely used in the study of acceptance of IT can influence the acceptance of u-Commerce.

Recently, the tourism industry faced a crisis due to COVID-19. Smart tourism that combines information and communication technology (ICT) is rapidly growing to overcome the crisis in the tourism industry. In order to revitalize the tourism industry after COVID-19, such as non-face-to-face and non-contact, smart tourism incorporating information and communication technology (ICT) is actively encouraged and promoted. The purpose of this study is to empirically verify how perceived pleasure, perceived awakening, and perceived domination, which are three important variables of emotional response theory, affect the intention to continue use through perceived usefulness, expectation, and satisfaction. The survey was conducted for two weeks from November 1 to 15, 2020. A total of 175 surveys were collected during the period and used for analysis. As a result of the study, first, perceived pleasure did not significantly affect perceived usefulness, expectation, satisfaction, and intention to continue use. Second, perceived awakening had a significant effect on expectations, but did not significantly affect perceived usefulness, satisfaction, and continued use intention. Third, perceived domination had a significant effect on perceived usefulness, expectation, and continued use intention. However, it did not significantly affect satisfaction. Fourth, perceived usefulness did not significantly affect satisfaction. Fifth, expectations had a significant effect on perceived usefulness and satisfaction. Sixth, satisfaction had a significant effect on the intention to continue use. Through this, companies and developers that provide online review content for aviation and hotels should know what part of the content is actually focused on and provide it to customers. In addition, content should be provided in consideration of the emotional aspects that aviation and hotel online review users feel while watching videos.

Recently, utilization of mobile Internet services is rapidly increasing. To properly accelerate the vitalization of mobile Internet usage, we have to know exactly about the factors affecting potential users' value recognition and intention to use. Technology acceptance model (TAM) is one of the most powerful reference framework for the individual user's adoption of IT innovations. This research borrowed core concept of TAM, and tried to explain users' intention to use mobile Internet by understanding the direct and indirect effects of subjective norm and perceived usefulness. To increase the explanatory power of the model, this paper introduced personal innovativeness as a key moderator variable. The research findings include; i) subjective norm has strong positive influence on perceived usefulness and intention to use, ii) perceived usefulness has positive influence on intention to use, iii) the influence of subject norm is greater than that of perceived usefulness, iv) positive influence of subjective norm on the perceived usefulness and intention to use are significantly stronger in the case of low personal innovativeness sub-group than the case of high personal innovativeness sub-group, and v) high personal innovativeness sub-group have shown strongly positive influence of perceived usefulness on the intention to use while there is no such significant relationship in the case of low personal innovativeness sub-group. Based on these findings, this paper proposed several guidelines to increase the adoption and the usage of mobile Internet; i) word-of-mouth is extremely important, ii) to form a good word-of-mouth, it will be very important to make early adopters and heavy users have positive direct experiences of using mobile Internet.

As having analyzed an advance research that had looked into how characteristics of information system affect use and success of the concerned system, the study determined that system quality, information quality and service quality are the fundamental requirements for a good accounting information system. In addition, based on perceived usefulness and perceived ease of use that have been selected as major variables related to information system acceptance proposed by Davis[10], the study conducted an empirical analysis on how such factors would influence performance of the accounting information system. According to the results from the analysis, the system quality one of the characteristics of the accounting information system was observed to have a significant influence on the perceived ease of use while both the information quality and the service quality would positively affect the perceived usefulness. Not only that, the perceived ease of use and the perceived usefulness were confirmed to be a significant factor to the performance, and with those results, all the theses of the study have been selected. As proved even with the information system success model, the system quality, the information quality and the service quality are definitely the most necessary elements for business management, and it also turned out that those elements would play an important role in several stages of the information system.

This study was examined empirically the relationship between exogenous and endogenous variables to use internet shopping malls. Exogenous variables in our model are retrieval simpleness, quality of order treatment, web reputation, update and system quality and endogenous variables are perceived usefulness, perceived ease of use and intention of using internet shopping malls. The results of the path analysis are shown as follows. All exogenous variables have a direct effect on perceived ease of use while both retrieval simpleness and update has a direct effect on perceived usefulness. The perceived ease of use has a direct effect on the intention of using internet shopping malls and has a indirect effect on the intention through perceived usefulness. Especially, web reputation among the exogenous variables has the strongest impact on the perceived ease of use and retrieval has the strongest impact on the perceived usefulness.

The purpose of the study was to explore the structural relationships between the intent to continue using Massive Open Online Courses (MOOCs) and its determinants based on the information systems continuance expectation-confirmation model. A total of 156 students from five different universities in Korea completed an online survey. An analysis by structural equation modeling revealed that college students' intent to continue using K-MOOC is partially supported by the model. Although perceived usefulness and confirmation are strong determinants of satisfaction and intent to continue using information systems in general, confirmation was the only significant predictor of satisfaction, the only significant predictor of intent to continue to use K-MOOC. Written responses on the survey were used to interpret the results. Findings indicate significant effects of confirmation on perceived usefulness, of confirmation on satisfaction, and of satisfaction on intent and insignificant effects of perceived usefulness on satisfaction and perceived usefulness on intent to continue. Substantial implications for future research and practices are discussed.
