This study highlight the role of perceived cost on user's continuance intention to use mobile TV service in china. We proposed research model based on the expectation-confirmation model(ECM) and reclaim 243 questionnaires from experienced users in china. Above all, the analysis results support significant relationship perceived variables, satisfaction, and continuance intention of mobile TV. First, while expectation confirmation has positive influence on perceived playfulness and satisfaction, the effect on perceived usefulness is not significant. Second, perceived cost can significantly predict perceived usefulness and satisfaction, however, we found no evidence of a statistically significant influence on perceived playfulness. Third, perceived usefulness and perceived playfulness have a positive influence on satisfaction, and perceived usefulness, satisfaction, and perceived playfulness have a positive influence on continuance intention. This results provide implications from both theoretical and managerial perspectives and the limitations have been discussed for future research.

Purpose: The purpose of this study is to examine the factors affecting the intention to continue using the metaverse platform service from the user's point of view. Methods: The study conducted a survey of experienced people using Zepeto, Ifland, Gather Town, Zep, Roblox, Fortnite, and Minecraft, which are virtual world types among metaverse types, and valid 415 data were analyzed by SPSS (ver 22.0) and R (ver 4.1.0) program packages. Results: As a result of empirical analysis, it was found that interactivity and social presence among the characteristics of metaverse affected expectation confirmation, and sensory affordance and functional affordance affected expectation confirmation as affordance factors. In addition, all four characteristics of metaverse, reliability, playfulness, interactivity, and social presence, were found to have the greatest affect on perceived usefulness, and it was analyzed that playfulness, social presence, and reliability were influenced in order. The affordance factor was also found to have a positive effect on physical affordance, sensory affordance, and functional affordance. This study was found that it had a positive effect on the relationship between expectation confirmation and satisfaction and the relationship between perceived usefulness and satisfaction. satisfaction was analyzed to lead to continuance intention. Conclusion: This study is meaningful in that it examines the perspective of users who can be called customers of metaverse platform services. Based on the results of this study, it is expected to have a significant effect on the development of metaverse platform services not only on platform operators that provide metaverse platform services but also on providers who plan events and education using metaverse platform services.

Purpose The purpose of this study is to investigate the effects of learning expectation and perceived knowledge sharing on user satisfaction and IS continuance in the Korean Army which is currently using the Regiments' Information System to help their Integrated Administration Management. Based on both the Information System(IS) Continuance Model and IS Success Model, this study also examine the role of system quality on user satisfaction. We develop a research model(structural equation model) and its hypotheses that learning expectation, perceived knowledge sharing, and system quality increase users' satisfaction, which leads to IS continuance. The effect of learning expectation on perceived knowledge sharing is also hypothesized. Design/methodology/approach Online Survey using e-mails was administered to test our research model and associated hypotheses. Among the 360 e-mail letters including our survey questionnaire, 285 responses were collected via e-mails. Meaningful 225 cases were analyzed for our study. SPSS Statistics 24.0 and SmartPLS 3.0 were used to analyze both measuremant test and hyotheses test by using the data set. Findings Survey results show that learning expectation(confirmation variable), learning expectation, perceived knowledge sharing(a perceived usefulness variable), and system quality(a system characteristic) each increases user satisfaction, which leads to IS continuance, under the control of the effect of habit to use information systems. Learning expectation also has a positive influence on perceived knowledge sharing. Theoretical and practical implications are presented.

Competition in the OTT (Over the Top) service market is getting fiercer since global OTT services enter the domestic market and existing platforms are actively reorganized. As powerful competitors with ultra-luxurious content continue to enter the marke with diversity required by users, various efforts are required for OTT service platforms to prevent subscriber churn in order to generate continuous revenue. Thus, this study tried to examine the effect of OTT service characteristics on continuous use intention through an empirical analysis based on Expectation-Confirmation Model(ECM). A total of 386 responses were collected from individuals who have experience or are currently using OTT service and analyzed using AMOS 24. Results show that content curation, content richness, and audience activity had a significant effect on expectation confirmation. Also, expectation confirmation had a significant effect on perceived usefulness and user satisfaction while perceived usefulness had a significant effect on user satisfaction, significantly influencing continuous intention to use OTT. Finally, price fairness was found to strengthen all proposed relationships. The findings are expected to provide useful information for service and content development for subscriber retention, which has the most direct impact on revenue generation of OTT service providers.

The purpose of this study is to identify the factors influencing the user's continuous usage intention of computer games. A research model was developed which shows that the independent variables of value, expectation confirmation, perceived enjoyment affect user satisfaction and continuous usage intention. To test the six hypotheses, survey data were collected from 104 respondents, and hypotheses tests as well as a confirmatory factor analysis were conducted using a partial least square analysis tool. The statistical analysis result showed that expectation confirmation had a significant positive effect on satisfaction, and satisfaction also had a strong positive effect on the game user's continuous usage intention. Perceived enjoyment showed a highly strong positive effect on satisfaction. In addition, satisfaction was found to have full mediation effects in the relationship between expectation confirmation and continuous usage intention, and perceived enjoyment and continuous usage intention respectively. This result provides an important implication that continuous usage intention occurs through user satisfaction, and also indicates the contribution of this study for the game industry. Another contribution of this study is to introduce critical independent variables from the marketing and information technology domains in order to explain continuous usage intention of computer games.

Theoretically and practically, it is very important to understand the way which tourist satisfaction is operated. The purpose of this study is to identify interaction among the determinants of tourist satisfacton process. A model of tourist satisfactioin process is developed based based on the confirmation / disconfirmation which is originated from consumer behavior literature. Three elements of the model include 'expectation','performance', and 'discrepancy between expectation and performance'. 340 questionnaires were delivered to find Everland visitors' perceptions of the determinants of tourist satisfaction. LISREL 8.14 was used to analyze the interaction among the determinants. The results are as follows : 1) 'expectation' has indirect effect on tourist satisfaction while 'performance' and 'discrepancy' has direct effect on the tourist satisfaction, 2) two precedent variables such as 'expectation' and 'performance' have indirect effect on the satisfaction through 'discrepancy',3) among the three determinants it is found that 'performance' is the most effective determinant of tourist satifaction, and 4) the model which was composed from the aspect of 'travel cost' was more effective to describing tourist satisfacton rather that from the aspect of 'service quality'.

Despite the characteristics of public data with various potentials, few studies have been conducted on general users who lack an understanding of data as well as on expansion of the service uses. This study examined which digital-service-quality factors affect the intention to continue using public data services based on the expectation confirmation theory. As a result of the analysis, satisfaction partially mediated between expectation agreement and continued use intention for understandability and efficiency, which were combined as one factor, and completely mediated the relationship between perceived usefulness expectation agreement and continued use intention. It can be seen that the more the understanding and usefulness of the information provided by the service is satisfied, the higher the willingness to use it. Accordingly, it suggested adding an electronic bookmark function and the provision of online community for users to improve the overall quality of services. This study is significant in that it provided evidence on which part to focus on when designing electronic services from the point of view of general users.

This study investigates the impact of tweets on box office revenue. Specifically, the study focuses on the times when tweets were written by examining the impact of pre- and post-consumption tweets on box office revenue; an examination that is based on Expectation Confirmation Theory. The study also investigates the impact of intention tweets versus subjective tweets and the impact of negative tweets on box office revenue. Targeting 120 movies released in the US between February and August 2012, this study collected tweet information on a daily basis from two weeks before the opening until the closing and box office revenue information. The results indicate that the disconfirmation that occurs in relation to the total number of pre-consumption tweets for a movie has a negative impact on box office revenue. This premise suggests that the formation of higher expectations of a movie does not always result in positive results in situations where tweets on perceived movie quality after watching spread rapidly. This study also reveals that intention tweets have stronger effects on box office revenue than subjective tweets.

Recently there has been an increase in interest and competition in sharing economy platforms. The success stories of many companies have spread in this field, such as Uber, but on the other hand, there are many other companies that have failed. We studied and analyzed the factors that affect the user's participation in the sharing economy platforms as an essential part of this system, and how to maintain the consumer's intention of use without compromising consumer satisfaction, as it has become an issue of great importance on the path to the success of the sharing platforms. Relying on the expanded valence framework and expectation confirmation theory as a basis, we constructed hypotheses that influence intention to participate in participatory platforms. Results show that system quality, trust, perceived benefits, and satisfaction are important factors that positively influence intention to continue to participate. This research is expected to help researchers move forward with research related to the future and help business managers understand user insights and integrate them with their business model to help the success, development and expansion of their business in the Kingdom of Saudi Arabia.
