Recently, following the development of FinTech technology that combines finance and information and communication technology, the need and social demands for a block chain technology-based trading system have increased significantly. In this study, a research model was developed and hypothesized through literature research on the concept of block chain technology, the technology acceptance model, and the unified theory of acceptance and use of technology. The research theories were tested by collecting data through surveys and analyzing the collected data. This study conducted empirical research to identify the factors influencing the user acceptance intention and utilization behavior of the block chain technology in introducing the block chain technology. First, factors affecting the acceptance intention of the blockchain user were performance expectation, effort expectation, social impact, and blockchain transparency variables. Second, the facilitation conditions and stakeholder confidence variables were analyzed as factors that did not affect the acceptability of the blockchain users. Third, variables such as blockchain transparency, stakeholder trust and intention of acceptance are factors that affect the usage behavior of the blockchain. Fourth, it was confirmed that the acceptance intention had a very high explanatory power on usage behavior of Blockchain technology.

The purpose of this study is to explore the determinants of actual demand for wireless broadband (WiBro) services in Korea. To this end, this study identifies conceptual definitions of diverse latent variables and determines the significance of the causal relationship between independent and dependent variables. It then presents the nomadic user concept by testing the moderator effect. This study also proposes a revised Unified Theory of Acceptance and Use of Technology (UTAUT) model, which is an appropriate model for wireless communication services and users' attributes. Prior research has concentrated exclusively on the Technology Acceptance Model (TAM) based on future potential users. Compared to previous studies, the current research model and analysis results are useful in not only academic but also industry contexts.

The current study investigates major factors which influence the acceptance of mobile internet services based on the theoretical backgrounds of the technology acceptance model(TAM) and the flow theory. This research extended the Davis' TAM model(1989) by including the flow concept as another major factor towards the intention to use the mobile device in order to explain the acceptance of divers mobile services. According to the marketing studies(Ghani & Desphande, 1994; Novak, Hoffman & Yung, 2000), flow is regarded a psychological state in which one is absorbed in something he or she is doing, and is known to be widely adopted in explaining one's acceptance in the area of game, sports, and even hobby. This study developed a research model to explain the use of mobile services employing usefulness, ease of use and flow as major research variables, and collected 221 survey responses from the high school students who had experiences with such mobile services as game and audio file download. The results of the current research indicates that usefulness and flow influence the intension to use mobile services, but the effect of ease of use did not appear significant to the intention to use. It was also found that flow affects both usefulness and ease of use, and then ease of use next influences usefulness.

Recently genuine products and good commerce have been threatened by distributing forgery in home and abroad markets. It is because most customers cannot distinguish whether genuine or forgery, so establishing of strict distribution system is needed. Therefore recently Genuine Guarantee System which can confirm genuine products has been developed using the Internet. The object of this system is protecting to purchase forgery by confirming distribution system. This system can provide a reliable environment of consumption. But to be diffused at distribution structure and applied, We require the understanding about not only technical side but behavior side. That is, we need to research the cause and process of using this new information system. in this research, we understand the cause of affection on the system's acceptance and define the suitability about the model according to Technology Acceptance Model by Davis. The above can build the suitable operating strategy and understand the criterion as a new business model.

The Technology Acceptance Model(TAM) proposed by Davis(1989) has been applied as a reliable and robust model in the study of user’s adoption of different technologies. However it is necessary to incorporate additional constructs to the original model in the quest for increased predictive power. This study investigate consumer’s acceptance of smart clothing applied by the extended TAM. Besides perceived ease of use and perceived usefulness, clothing involvement is included in the extended TAM. Data were collected from the adults over 20 years old living in Seoul and other metropolitan areas from March 2 to March 12, 2009. 815 copies of data were analyzed to examine a structural model and test research hypotheses using AMOS package. The study showed the extended TAM for smart clothing was validated empirically in predicting the individual’s acceptance of smart clothing and 5 hypotheses among 7 hypotheses were supported. Specifically, perceived ease of use, perceived usefulness, and clothing involvement were the factors affecting attitude toward smart clothing. Attitude toward smart clothing was influenced directly by perceived usefulness and clothing involvement but influenced indirectly by perceived ease of use. Acceptance intention toward smart clothing was influenced strongly by attitude. From a theoretical point of view, the study extended the TAM for smart clothing. Moreover, this study would be beneficial for those who would develop smart clothing by providing information about attitude and acceptance intention of smart clothing consumers.

The purpose of this study was to examine how Korean students accept and use mobile-assisted language learning (MALL) and investigate related factors that potentially affect MALL usage. The participants were 244 undergraduate students who were surveyed with a questionnaire. The research model, which included students' self-efficacy, content reliability, interactivity, perceived enjoyment, perceived usefulness, perceived ease of use, attitude, and behavioral intention to use MALL, was developed based on the technology acceptance model (TAM). The structural equation modeling (SEM) technique was employed in order to analyze the overall results of modified TAM and the research model. The results indicated that TAM was a good theoretical tool to understand students' acceptance of MALL. In addition, all constructs, with the exception of self-efficacy and interactivity, had significant effects on students' acceptance possibilities of MALL. Limitations and suggestions for the further study are also presented.

Technology Acceptance Model (TAM) has been widely used for predicting behavioral processes in which information technologies were accepted, but several previous studies point out that TAM may not explain the adoption process of complex information technologies effectively. This study empirically tests the limitation of TAM, and suggests a proposed research model by incorporating the concept of the perceived behavioral control into TAM. Study findings indicate the proposed model can predict the adoption process better than TAM does.

As network technologies evolve and so-called smart technologies appear, applications of smartphones are being applied in widespread areas. In general, the adoption of smartphones is different from the adoption of information systems. Thus, we tried to find out factors which may affect the user acceptance behavior. However, there have been some academic studies that analyzed the factors that affect user acceptance of smartphones, and their relationships. Under this academic background, we develop a model to examine how smartphones are accepted by users based on technology acceptance model. The theoretical model is validated through an online survey of smartphone users from two universities in Seoul, Korea. The results reveal that the users will have positive attitude towards adopting the smartphone when they perceive that the usage of smartphones is useful. We also find that the perceived usefulness of the smartphone is affected by the perceived ease of use and the media richness. The results also suggest that the perceived ease of use is determined by the self-efficacy whereas the intention to use smartphones is determined bv the perceived usefulness, the self-efficacy, and the attitude toward smartphnes' usage. Theoretical and practical implications are discussed.

Technology Acceptance Model (TAM) has been a basis model for testing technology use. Post researches of TAM have been conducted with the updating the TAM by adding new independent variables in order to increase the explanatory power of the model. However, the problem is that different independent variables have to be required to keep the explanatory power whenever adopting particular technology. This might reduce the generality of the research model. Thus in order to increase the generality of the model, this study reviewed the previous researches and collected the independent variables used, and regrouped them into three basic independent constructs. New research model was designed with three basic independent constructs with three constructs selected for the involuntary information technology usage environment. Finally, this study concluded that new technology acceptance model could be used to explain the use of new technology without any adding new particular independent variables.

With e-commerce becoming international, understanding the effects of national culture in consumer acceptance of e-commerce is required. This study examines consumer e-commerce acceptance in Korea and China. The research model consisting of perceived usefulness, perceived ease of use, trust and perceived risk was proposed, and the hypotheses based on Hofstede's cultural dimensions of power distance, individualism/collectivism, masculinity/femininity, uncertainty avoidance and long-term orientation, were established. The results show that perceived usefulness contributes less to consumer acceptance of e-commerce in China than it does in Korea. In addition, perceived ease of use contributes more to consumer acceptance of e-commerce in China. Trust contributes significantly to consumer acceptance of e-commerce in both countries, but perceived risk didn't influence consumer acceptance of e-commerce in either country. The contribution of this study is to provide strategic insights for successfully managing cross-cultural e-commerce.
