The purpose of this study is to explain users' wearable healthcare device adoption using performance expectancy, effort expectancy, facilitating condition, hedonic motivation and price value of UTAUT2, and to identify the causal relationship between intention to use wearable healthcare device and innovativeness. The research model proposed in this study is based on UTAUT2(Extended Unified Theory of Acceptance and Use of Technology). In specific, performance expectancy, effort expectancy, facilitating condition, hedonic motivation and price value of UTAUT2 and innovativeness are adopted in our research model. To validate the research model, we carry out the analysis of the survey data using Smart PLS 3.0 to test the hypotheses. According to the empirical analysis results, this study confirms that Innovativeness have significant effects on the performance expectancy, effort expectancy, Facilitating condition, Hedonic motivation, and price Value of wearable healthcare devices. It also finds that the performance expectancy, effort expectancy, Facilitating condition, hedonic motivation, and price value affects the intention to use wearable healthcare devices.

The purpose of this study is to analyze mediating effects of sense of community between Ego-identity and multicultural acceptance. Struatural analysis is performed with six - year panel survey data of elementary school 1st grade students and middle school 1st grade students from Korean child- Youth Panel survey. The subjects of six - year panel survey data are the sixth grade in the elementary school and High school seniors. The results are as follows. First of all, there are differences in Ego-identity, sense of community and multicultural acceptance between the sixth grade in the elementary school and high school seniors. Second, they are related. Third, regression analysis shows that Ego-identity and sense of community have an affect on multicultural acceptance. Fourth, partial mediating effect is suitable for whole youth and sixth grader and complect mediation effect is suitable for high school seniors. In early adolescents, Ego-identity plays a direct role in multicultural acceptance. But in late adolescents, sense of community plays a direct role in multicultural acceptance. Base on these results, for improving adolescents multicultural acceptance, It has suggested educational programs that helps to enhance Ego-identity and sense of community.

In this paper we investigate the factors influencing the purchase intention of Smart-Phone which was introduced recently. Smart-Phone is a new information technology that converges PDA into a mobile phone. It has a various functions such as phone, information processing, Internet search etc. New information technology like Smart-Phone gives us a very important and interesting research issue, which is to find and prove the factors influencing the purchase intention. We try to find and prove the factors influencing the purchase intention of Smart-Phone by expanding Technology Acceptance Model. We include the perceived playfulness to the research model in order to analyze the factors. This empirical paper proves that the perceived usefulness, the perceived ease-of-use, and the perceived playfulness give positive effects to the purchase intention. In addition, this paper indicates some managerial implications that various and useful applications and the easy user interface can help to increase the degree of user acceptance.

This study analyzed the factors that affect acceptance of online direct marketing in agricultural companies. Empirical analysis was conducted using the research model based on the individual's technology acceptance model (TAM) and the information technology adoption models in organizations. These models have four dimensions: 1) technology characteristics, which include perceived usefulness and perceived ease of use of TAM 2) CEO characteristics, which including the innovativeness and IT capability of CEOs; 3) organizational readiness, which include financial, technological, and human resources capabilities and 4) environment and external pressure, which include government support and changes to the Internet environment. These concepts were empirically tested. A total of 209 valid data were collected through questionnaires and analyzed using confirmatory factor analysis and path analysis through the application of structural equation modeling. Results show that perceived usefulness, IT capability of CEOs, and changes to the Internet environment have significant effects on the adoption intention of online direct marketing. However, perceived ease of use, CEO innovativeness, government support, and the variables of organizational readiness dimension did not have significant effects on adoption intention. This study suggests practical implications for adoption of online direct marketing in agricultural companies.

Electronic payment is a very crucial function in electronic commerce. As electronic commercial transactions develop on a mobile basis, a variety of electronic payment services that can be conveniently used are appearing. In particular, mobile easy payment services improve the user's convenience of payment and give a positive effect on activating online transactions. In this study we investigate empirically the factors influencing the user resistance to mobile easy payment services. Especially, we compares the main acceptance factors of the mobile easy payment services with the main acceptance resistance factors of the services. By doing that, we derive the implications that could contribute to the vitalizations of the mobile easy payment service market. The research model includes "perceived risk" as a main acceptance resistance factor, and "easy of use" and "usefulness" as the main acceptance factors. The relationship among these three factors, "use conflict", and "user resistance" is expressed in the model. We analyze the model by Structural Equation Model. The results proves that all the research hypotheses are adopted except for the impact of "ease of use" on "use conflict", and that users of mobile easy payment services think of "usefulness" more important than "risk".

Recent proliferation of advanced technologies such as wireless communication, mobile, sensor technology and so on has caused significant changes in a traffic environment. Human beings, in particular drivers, as well as roads and vehicles were advanced on information, intelligence and automation thanks to those advanced technologies; Intelligent Transport Systems (ITS) and autonomous vehicles are the results of changes in a traffic environment. This study proposed considerations when designing a simulation model for future transportation environments, which are difficult to predict the change by means of advanced technologies. First of all, approximability, flexibility and scalability were defined as a macroscopic concept for a simulation model design. For actual similarity, calibration is one of the most important steps in simulation, and Physical layer and MAC layer should be considered for the implementation of the communication characteristics. Interface, such as API, for inserting the additional models of future traffic environments should be considered. A flexible design based on compatibility is more important rather than a massive structure with inherent many functions. Distributed computing with optimized H/W and S/W together is required for experimental scale. The results of this study are expected to be used to the design of future traffic simulation.

As smart devices have proliferated and mobile networks have accelerated, various wired IT(Information Technology) services are transplanted in wireless environments. Cloud computing service, enabling individual users or firm users to download data from a server and upload data after manipulating data, is also available in mobile devices. Unlike cloud service in wired network environments, mobile cloud service provides differentiated aspects in mobility, security issues caused by persistent connection to networks. In this paper we aim to analyze the factors affecting the user attitude and their structural relationships towards mobile cloud service use. We extend TAM(Technology Acceptance Model) to consider the characteristics of mobile environments. Research findings, analyzed by SEM(Structural Equation Model), are explained and practical implications are presented with concluding remarks.
