The purpose of this study is to investigate factors influencing continuous usage intention of mobile learning and suggest practical strategies to enhance learners' continuous usage intention of mobile learning. In this study, we hypothesized that system quality, information quality, service quality and personal innovativeness have a positive effect on effort expectancy and performance expectancy, which ultimately have a positive effect on continuous usage intention. In order to examine structural relationship among variables, we surveyed 279 students who took courses at W Cyber University in 2013 fall semester. After collecting data, we examined causal relationship among variables using Structural Equation Modeling. The results of this study are as follows: First, system quality and personal innovativeness significantly affect effort expectancy. Second, information quality, service quality and personal innovativeness significantly affect performance expectancy. Last of all, effort expectancy and performance expectancy significantly affect continuous usage intention of mobile learning.

CAS is an access control system by which only legal users can access contents. IPTV is a spotlighted system that uses CAS. H.264/SVC is a coding standard that provides a scalable coding method by which users who are in various network environments and have various devices can receive the contents. In this method, the contents are coded in a layered structure to make users choose the quality of the receiving contents. Therefore, contents provider should be able to control users to access only appropriate contents according to their subscriptions. The structure of CAS being employed in many applications is not suitable to control access for H.264/SVC. In this paper, we provide an efficient access control method and a key management method for H.264/SVC contents using CAS.

The purpose of this study is to develop the service scales of festival quality. We derived five constituent factors, service quality measures of local festivals through the extensive literature review in Previous studies. We named these qualities "COKITQUAL" that is consist of Convenience, Information, Kindness, Operation, Corporeity. We conducted the empirical analysis for the participants in "Hwacheon Sancheoneo Festival" to verify the "COKITQUAL". As the result, Information, Kindness, Operation affected positively on Festival Satisfaction among all SERVQUALs. However, Convenience and Corporeity did not positively affected on the dependent variable. And then, Festival Satisfaction positively affected on on Behavior Intention. This study developed the Service quality concerned with local festivals which is crucial fundamentals to quantify Festival SERVQUAL through empirical study. The proper applications and usage of these newly introduced local festival qualities enable to acquire the sustainable competitive advantage in local festival.

This study reviewed previous studies about Relationships between Festival Participation and Festival Evaluations. Also relationships among the quality of festival participation and festival evaluation factors identified from previous researches were studied. According to the results in view of the relationship between the quality of festival participation and festival performances, hypotheses about the relationship between physical environment and contents identification and about the one between customer experience awareness and loyalty were rejected. On the other hand, the rest of hypotheses were supported having positive impacts.

This study was to evaluate the quality of academic information services provided by Naver Academic Information Service, Google Scholar, and MS Academic Search. This academic information services were evaluated in terms of the contents, service, and effectiveness. 135 four year college students were recruited for the survey. The results showed that the Google Scholar in contents section had higher score than Naver and MS Academic Search. In regard to service, Google Scholar had higher score in retrieval section while Naver had higher score in design section respectively. Finally, both Google Scholar and Naver in the access section had higher score than MS Academic Search.

With the expansion of EC and the development of culture industry, Web-site shopping of cultural products have become recognized as one of the major purchasing channels for customers, as well as one of the competitive distribution channels for film distributors or theater group. The research is to investigate the impact of information quality and user interface quality on information service satisfaction and online purchasing intention of cultural products. The results of this study are as follows: 1) Both information quality and interface quality have meaningful influence on information service satisfaction and purchase intention. 2) Information service satisfaction gives significant impact on online purchasing intention irrespective of the level of customer involvement. 3) Information quality has a meaningful influence on online purchasing intention in case of high level of customer involvement, while interface quality gives strong impact on online purchasing intention in case of low level of consumer involvement. In conclusion, there is a need to consider the level of customer involvement for building a successful marketing strategy of online purchase sites of cultural products.

인터넷이 생활의 저변에 확산된 현재의 환경에서 디지털콘텐츠를 접할 수 있는 기회가 많아지고 더불어 디지털콘텐츠를 통해 부가가치를 생산해 내려는 산업적 관심이 높아져 가고 있다. 디지털콘텐츠의 장점을 적절히 활용하여 수익을 창출하기 위해서는 무엇보다 디지털콘텐츠가 가지는 특성을 이해하는 것이 필수적이라 할 수 있다. 본 연구에서는 경험재로써의 디지털콘텐츠에 초점을 두고 사용자가 디지털콘텐츠를 경험하면서 느끼게 되는 특성을 도출해 내었다. 문헌조사를 통해 디지털콘텐츠를 이루는 8개의 element를 찾아내어 각 element를 이용하는 사용자의 디지털콘텐츠 인식 구조를 도출해내기 위해 Repertory Grid 방법을 수행하였다. 5점 척도로 점수를 부여하는 Repertory Grid 방법으로 인터뷰와 인터넷을 이용한 설문을 동시에 시행하여 피험자로부터 48개의 construct을 도출해냈다. 본 연구결과의 의의는 미리 정의된 특성을 부여하지 않고 순수하게 사용자의 경험으로부터 도출되는 디지털콘텐츠의 특성을 도출해 내었다는 데 있다. 즉 디지털콘텐츠의 본질을 정의하고 분류체계, 품질체계를 규정할 수 있는 연구의 초석을 마련하였다.

All medical information system stakeholders and the environment exists. Medical information systems for development in these environments and non-functional requirements, functional requirements and quality goals are to be met. In order to achieve these goals in a variety of ways currently being made to develop information systems and various applications are emerging. However, the process of developing these health information systems meet the basic requirements and does not consider that from the point of view should not be separate. This study of the development of health information systems related to quality measurement indicators for the analysis software architectures, and medical information, information quality evaluation of service quality information associated indicators evaluation are offered. This way of associated indicators for the quality of the output sum and analyze the trends in software architecture u-Healthcare should be available for assessment. Quality score compared with pre-set goals for achievement and satisfaction levels of analysis further support the cause excerpt field use in analysis and improvement is possible.
