Social network service(SNS), provided by social network sites such as Facebook, Twitter and Cyworld is rapidly growing in online business. Furthermore, many companies have growing interests in finding effective ways to use SNSs for their innovations, marketing and advertisement. In fact, firms have recognized the utility value of the SNS for their business. In this aspect, this study attempts to identify key factors influencing the intention to continuous use of SNSs. Based on the UTAUT(the Unified Theory of Acceptance and Usage of Technology)model, this study proposes the research model, including the effects of social network service characteristics(social relationship support, information sharing, image expression) and individual characteristics(self-disclosure, extroversion, familiarity) on performance expectancy as well as the moderating effect of perceived information security among UTAUT variables. The 412T sets of data collected in a survey were tested against the modeling using SEM using SmartPLS. Results indicated that social network service and individual characteristics had significant effect on performance expectancy with exception of self-disclosure. In addition, the moderating effect of perceived information security had significant effect.

Recently, due to the proliferation of smartphones, users of mobile multimedia services which are based on wireless internet without constraint of the time and places are significantly increased. In this study, considering the characteristics of mobile multimedia and the user behavior, we analyse the factors which have an effect on the behavioral intention to use the mobile multimedia services. For this purpose, we use the model which is based on Technology Accepted Model (TAM) and add two constructs; the perceived enjoyment and the perceived risk. A survey data for 280 students at the K cyber university is used for statistical analysis As a result, the perceived ease of use affects the perceived usefulness and the perceived enjoyment, and the perceived ease of use. And the perceived usefulness and perceived enjoyment affect continuous intention to use. On the other hand, the hypothesis which the perceived risk would affect adversely the continuous intention to use is rejected. Through this study, we expect to provide the useful implications for the mobile multimedia services and contribute to the development of strategy for them.

The survey results of 352 Vietnamese customers using Fintech services, reliability test and extended post-acceptance model (EPAM) which is based on PAM and ECT models. From the survey, we further found out that perceived security (BSS) has no direct impact on continued intention to use, while perceived security (BSS) has positive impact on confirmation (CON), similarly, perceived usefulness (PU) and user's satisfaction (SES). Knowledge of the Mobile Fintech payment service (KNOW) has a positive impact on perceived security (BSS). Confirmation (CON) has a positive influence on perceived usefulness but in the meanwhile it has created a negative impact on user's satisfaction (SES). From the survey it can also tell that user's attitude (ATT) and enterprise image (IMG) both have a positive impact on continual intention to use Fintech services. From the research results, we also propose some recommendation to enhance the continual intention to use Fintech services in Vietnam.

최근 모바일 디바이스 보급의 확산으로 다양한 기종의 디바이스를 다수 보유중인 사용자의 수가 지속적으로 증가하고 있는 추세이다. 이에 따라 하나의 미디어 콘텐츠를 사용자가 보유한 다양한 기기에서 서로 공유해야 할 필요성이 증가하고 있으며, 이는 연결성, 이동성, 통합성 기반의 N-screen 서비스의 확대를 가지고 왔다. N-screen 서비스는 하나의 미디어 콘텐츠를 공유하여 사용자가 보유한 다양한 디바이스에서 서로 이어보기가 가능하게끔 서비스를 제공한다. 그러나 N-screen 서비스들은 서비스 제공 사업자의 전용 플랫폼에서 시행되는 문제점을 가지고 있다. 따라서 본 논문은 개방형 서비스 플랫폼에서의 이어보기 기능의 설계를 위하여 시험적으로 이어보기 기능을 제공하는 RESTful 기반의 이어보기 기능 제공이 가능한 프로토타입 프로그램을 개발하였으며 동작검증은 Android - PC간 시행하였다.
