This study looked at what the perceived recognition and user characteristics of 3D printers have to do with perceived value and intention of continuing use. The data collection was conducted by 300 people, including employees who lived in Korea and used 3D printers. Research has shown that firstly, perceptual perception affects perceived values and intended use. Second, user characteristics have been shown to affect perceived value and intended use. Third, it appears to have a positive effect on perceived values and the intention of continuous use. Therefore, by fully recognizing the usefulness and ease of 3D printers to consumers, and by making them aware of the convenience and reliability of consumers, it will be effective if a strategy is established that has put a lot of interest and effort into making 3D printers more popular and active by enhancing consumers' intention to continuously use 3D printers.

Cloud storage service has the potential to be a core infrastructure for the future mobile and Internet service; thus related service providers have been investing in it and trying to attract as many users as possible. In addition, those need to find out what motivates the users to keep using their service not only to attract new customers but also to secure their subscribers. Therefore, this study will examine its relationship with user's motivation based on the extended TAM model with external variables for objective research about continuous use of cloud storage service. As a result, it was found that personal innovativeness, self efficacy, functional attributes, and psychological switching cost influence the continuous use of cloud storage service. Also, it is expected they can guide service providers to the right track when setting up their business strategy in the future.

With the active smartphones user exceeding 500 million by the end of 2014, China has now become the largest smartphone market in the world. Smartphone companies provide variety of information through a range of applications, such as communications, entertainment, games, and so on. There were many studies conducted about the user acceptance and continuous intention of mobile service. However, it is still not quite clear what factors attract people to reuse smartphone in China. This paper examines the continuous intention of smartphone about Chinese customers. This study incorporates perceived enjoyment as a additional construct into a extended TAM model, by integrating a hedonic service of smartphone. We propose a research model that reflects the individual characteristics and usage contexts of smartphone, such as innovativeness, social influence, and service quality, and analyze the structural relationship between the main variables through empirical study. This study empirically investigated a research model and conducted a survey of smartphone service users in China. Our study proved that perceived enjoyment has a positive influence on continuous intention to use smartphone services. This paper provides the managers an insight that smartphone companies should take more consideration on how to provide more enjoyable service and attract customers to reuse their services.

This study examined the concept and usage moderated mediating model in structural equation modeling. The theoretical model and hypothesis were developed based on the Location-Based application's Expectancy disconfirmation, Location-Based application's satisfaction, Location-Based application's continuous usage intention, service trust. The statistical results of the two model were compared: one was free model(positive/negative) and the other was the Moderated Mediating Model(positive/negative). A structure equation model analysis was carried out to test the research model. Further studies are necessary to Ssupport the research hypotheses.

With a recent rise of various chatbot services, this study attempts to explore the role of chatbot users'' psychological characteristics by applying the self-determination theory. In particular,this study investigates (a) the relationship between chatbot users' psychological needs(perceived autonomy, perceived competence, perceived relatedness) and user satisfaction, continuous intention to use, and (b) the moderating effect of chatbot type and user motivations. Based upon a survey, the results revealed that perceived autonomy, competence, and relatedness had significant positive effects on user satisfaction and continuous intention to use. The results also confirmed that the user satisfaction had a significant positive effect on the continuous intention to use. The moderating effect of social and relational motivation was found between perceived autonomy, competence, relatedness and user satisfaction. The implications are discussed for furthering the development of chatbot services.

The purpose of this study is to explore the mechanisms influencing consumers' continued intention to use live-streaming e-commerce for shopping, providing strategic recommendations for businesses to optimize live-streaming activities and enhance consumers' shopping experiences. In this paper, we innovatively integrate the UTAUT2 and ECM theoretical models to construct a comprehensive research framework. This framework not only thoroughly reveals the multi-dimensional variables that affect consumers' continuous usage intentions but also delves deeply into the interrelationships among these variables. We collected data extensively through surveys and utilized the Structural Equation Modeling and Bootstrapping methods for analysis. The research results indicate that performance expectation plays a crucial role in determining the continuous usage intention; satisfaction exerts a significant mediating effect between performance expectation and four other variables concerning continuous usage intention; and expectation confirmation stands out as the most prominent factor in enhancing satisfaction.

The study has been derived through the empirical analysis so as to find the Continuous Usage of Electronic Official Document 24 System. Total of 236 questionnaires were analysis to users who used or experienced the Electronic Official Document 24 System. As a result of the analysis First Accuracy, Convenience, and Security have a positive(+) effect on Ease of Use. However, Compatibility and Innovation were not effect on Ease of Use Second, Accuracy, Convenience, Security, and Innovation have a positive(+) effect on Perceived Usefulness. However, Compatibility was not effect on Perceived Usefulness. Third, Behavioral Costs have a positive(+) effect Continuous Intention and perceived ease of use positively affects perceived usefulness and Continuous Intention. Finally, perceived usefulness also has a positive effect on the Continuous Intention.

As smartphone was distributed widely usage of SNS is growing. Because of ots characteristics, SNS can sustain only when user uses SNS, users' intention to persist use of SNS is very important. Therefore in this study, psychological needs and immersion, the quality of SNS were chosen as impact variables to verify whether they affect the persistance of Facebook usage. A survey was conducted to 165 of Facebook user, and the result showed that compentence and relatedness significantly affeted immersino, and compentence and system quality significantly affected Facebook persistence.

Although multimedia messaging services (MMS) are becoming increasingly popular, and companies are maximizing the use of their content, few systematic studies on MMSs exist. This study examined technology acceptance factors for MMS in 398 young people aged 10 to 39 to identify MMS users' continuous intention to use (CITU) via a questionnaire and SPSS21 and PLS-Graph 3.0. The results showed that perceived media richness (PMR) had a positive effect on perceived usefulness, perceived ease of use, and most importantly, CITU. Furthermore, PMR had a positive effect on perceived ease of use as a moderating effect on experience. To increase use efficiency in MMSs based on these results, media richness, perceived ease of use, perceived usefulness, and user experience may serve as important variables affecting users' CITU and provide a basic reference and development direction for MMS users. Future studies should include more variables and examine additional factors when analyzing the structural model.
