가상강좌에 대한 사회적 관심이 높아지고 각종 교육기관에서 다양한 방식의 서비스를 제공하고 있음에도 가상강좌의 효과 즉, 가상강좌 수강생들의 만족을 측정하는 도구의 개발은 상대적으로 미흡한 실정이다. 특히 초기의 가상강좌가 정보기술을 이용한 실험적인 형태에서 벗어나 기존의 오프라인 교육을 대치할 수 있는 중요한 도구로 대두되고 있다는 점을 감안할 때 가상강좌의 효과를 측정하기 위한 도구는 좀 더 종합적인 접근 방식이 요구되고 있다. 본 연구에서는 가상강좌 특히 인터넷을 기반으로 하는 가상강좌의 네 가지 요소인 학습관리시스템, 강의 컨텐츠, 학습에 대한 인적 서비스 그리고 학생 자신의 심리적 상태 등을 고려한 종합적인 접근에 의한 가상강좌 만족 모형을 제시하고 그 측정도구에 대한 타당성을 검증하도록 한다. 이를 위해 정보기술 사용 측면, 정보품질적 측면, 서비스 관리적 측면 그리고 사회심리학적 측면에서 가상강좌 측면에 만족을 주는 이론적 변수 및 측정도구를 제시하고 측정도구에 대한 타당성을 실증적으로 검증한다.

The purpose of this study is finding factors affecting the students' use of the Cyber Home Learning Service System and exploring the direction of this system. It is based on the TAM(Technology Acceptance Model) and the result of the previous studies, six external and three internal factors influencing the sue of Cyber Home Learning Service System were extracted. The participants were 201 elementary school students in Pusan. The response of the questionnaire was gathered by online survey system. To analyze the data and the hypothesis, multiple regression and factor analysis were explored. The result indicated that (a) "usefulness" and "future-intention" affected statically to the use, (b) "usefulness" to the future-intention, (c) "subjective judgement", "fun", and "ease of use" to the usefulness, (d) "self-efficiency" and "contents quality" to the ease of use.

This study presents research into the patterns that affect the understanding and acceptance of healthcare management systems as part of a healthcare information technology infrastructure targeted at university students. The participants were 623 university students in D city and K province. This study employed a descriptive and correlational cross-sectional survey and made use of the ubiquitous healthcare management services measurement scale. 48.5% of respondents had accessed healthcare-related information on the Internet. Among the independent variables of general characteristics related to perceived susceptibility was found to have adj $R^2$ of 11% while the other dependent factors reported much lower between 0.5 to 4.7%. Female respondents, medical-related majors, self-efficacy, and intention to use had significant positive effects while health beliefs and concern had a significant negative effect on the intentional acceptance of healthcare information technology systems.

Recently, the use of prepaid electronic payments such as electronic wallets, digital currency and prepaid points is gradually increasing. Prepaid electronic payments has the characteristic of being used after charging first. This study empirically investigated the factors affecting the intention to use online charging in order to help improve the service that require prepaid recharge by applying transformed TAM. Since there are not many previous studies for the intention to use online charging, we extract factors through preceding researches for electronic cash and mobile easy payment. Also we analyze the intention to use online charging for transportation card users, focusing on the moderating effects. As a result of the study, it was found that 'convenience', 'ubiquity', and 'self-efficacy' among the independent variables had a positive (+) effect on mediation variable 'perceived usefulness'. 'Perceived usefulness' was analyzed to have a significant influence on the dependent variable 'usage intention'. According to users' gender, internet usage time, internet shopping frequency, online charging frequency and transportation card usage type, the moderating effect was significant on 'perceived usefulness' and 'usage intention'. As an implication, it was suggested that service improvement and differentiated marketing are needed in direction of increasing the usefulness of services. Additional research directions were proposed for services such as e-wallets, prepaid points and digital currencies by adding other factors and moderate variables.

This study attempted to analyze factors influencing S-DMB adoption. The theoretical background of this study is 'Technology acceptance model.' Based on this theory and literature review this study set 5 hypotheses. For this research, a survey was conducted by online research lab. from October 25 to 31. Data were collected from 350 subjects. Complete and useable questionnaires were received from 303 respondents. The result and conclusion are as follow: 'Instant accessibility,' 'service quality,' 'Cost,' 'advertising,' 'perceived easy of use' are significant factors influencing 'perceived usefulness'. 'Compatibility,' is a significant variable influencing 'perceived easy of use'. However, 'self efficacy' and 'innovativeness' are not significant factors influencing 'perceived easy of use.' The result of the analysis showed that most of the hypotheses were verified the same as preceding studies, but some results were different with the result of preceding studies. Therefore, it implies the characteristics of S-DMB different with other IT systems and mass media that were research subject mostly before, and it influences the result of this study as well.

SNS uses the Internet as its base. It is created in order to achieve communication between the users. Up until now, most previous research were focused on the users of SNS. But, there are still a great deal of people who do not use or discontinuously use SNS. This is because users have natural resistance against SNS when using the service. In this study, time shortage perception, awareness of SNS, self-efficacy, suitability, information quality of SNS, subjective norm and privacy concern are considered as influence factors by previous research. An empirical study for Chinese students and internet users was conducted to identify how these factors influence perceived risk and perceived usefulness, and how this influence to user's resistance. This study can explain the reason why users don't use SNS and resist SNS use.
