More and more cloud computing services are being applied in various fields; however, it is difficult for users and cloud computing service platforms to establish trust among each other. The trust value cannot be measured accurately or effectively. To solve this problem, we design a service-oriented cloud trust assessment model using a cloud model. We also design a subjective preference weight allocation (SPWA) algorithm. A flexible weight model is advanced by combining SPWA with the entropy method. Aiming at the fuzziness and subjectivity of trust, the cloud model is used to measure the trust value of various cloud computing services. The SPWA algorithm is used to integrate each evaluation result to obtain the trust evaluation value of the entire cloud service provider.

This study aimed to investigate the roles of three health-oriented personal factors-health technology innovativeness (HTI), health consciousness (HC), and health information orientation (HIO)-in determining Koreans' perceptions about telemedicine. Based on an extended version of the technology acceptance model (TAM), two perceptual components-perceived usefulness (PU) and perceived ease of use (PEOU)-of telemedicine were considered for this investigation. Data from 699 usable surveys were analyzed using path analysis. The results from the path analysis indicated that while HTI and HC had no or limited effects on the PU and PEOU of telemedicine, the effects of HIO on those two perceptual components of telemedicine were statistically significant. Moreover, the results from the path analysis showed that there were significant regional differences in the effects of HTI and HC on the PU and PEOU of telemedicine. In general, these effects were greater among the metropolitan residents than they were among the rural residents.

The purpose of this study is to analyze the information service and the design of the information system of LG Science Land and NSDL which was designed as Integrated Information System in Science Digital Library for youth. After that, the requirement and inclination of the system user was analyzed through on-line questionnaire and finally the Subjective-Oriented Directory System was modified in detail as improvement issue of the system. This study has a significance in designing a user-friendly information environment that the youth can access information in science more conveniently and Proving the efficiency of it.

The SMIL(Synchronized Multimedia Integration Language) documents are represented as logical structure information, spatial layout structure information, temporal synchronization structure information and hyperlink structure information, according as the structural characteristics of SMIL documents based on XML. This paper proposes the effective modeling and query method for the multi -structure information of inherent SMIL documents. In particular, we present the object-oriented modeling by using UML class diagram in order to represent the objects classes for the structured information of SMIL documents, and the hierarchical structure and the relationships for the objects classes. In addition, the objects classes definition is specified in compliance with SQL3 for database standard language. We also propose the access method and the query representation for hierarchical structure in order to retrieve efficiently the structural objects of SMIL documents.

Information-oriented society caused by development of computer and communication has benefited us with a convenient life. However, its side effects are widespread, which increases the need of the education of information and communication ethics. In this study, we take an approach of virtue education to cultivate information and communication ethics, as virtue is required to make a desirable information-oriented society. Lessons of Myungsimbogam were administered to the 6th grade elementary school students for nine weeks. The results demonstrated positive effects in internet addiction, chat addiction, and netiquette for the experimental group. However, no positive effects in game addiction were found.

Web 2.0 could influence the teaching and learning system significantly due to its characteristics to utilize information using internet in various ways, to create information, and to reorganize it through information sharing. In this new environment of information-oriented classes using the computer, positive education method is required to develop new teaching/learning method based on the internet web 2.0 in order to fulfill the learner's intellectual curiosity and to lead the future-oriented classes. This paper proposed a teaching-learning models in the web 2.0-based internet information education and its effect analysis.

With the evolution to distributed computing technology, the concept of conventional client/server function has been advanced to Service-Oriented Architecture, which can share the information between heterogeneous systems as services. To success Service-Oriented Architecture, the conjunction between business layer and application layer is one of the important techniques. In this paper, we classify services into two views, vertical and horizontal, and introduce matching technique with service classification for SOA.
