Recent research on mobile Internet protocol television and digital right management (DRM) interconnections has focused on multimedia technologies designed to enhance content scalability and adaptive content distribution. However, due to the architectural and scalable limitations, recent systems are not flexible and securable with respect to their adaptive content distribution and protective policy management. Therefore, we propose a content protective multi-agent platform that provides secure multimedia services, correlation management, pattern-based management, and multi-source multi-use (MsMu)-based services. Our architecture, supported by DRM, lets us create a rich set of MsMu-based content protection and seamless multimedia services through the extension of one source multi-use (OsMu)-based content services. We have verified our platform, which provides scalable and securable services with a 17% lower service response time by using a testbed.

Although 19 years have passed since the enforcement of the Framework Act on Health and Medical Services, the Plans for Development of Health and Medical Services has not been established. This Plan is a 5-year basic long-term plan that covers the whole of health and medical services. This Plan should point to the direction of 30 long-term plans of healthcare, and this Plan should serve as a combination and coordination of 30 long-term plans and 22 related laws. The United States, the United Kingdom, and Japan have established long-term healthcare plans (4-, 10-, and 20-year plans, respectively). The long-term health plan of the United States has been approached bottom-up, those of the United Kingdom and Japan have been approached top-down. The rapid environmental changes that Korea is and will be experiencing emphasize urgently the need for establishing the Plan for Development of Health and Medical Services.

This study examines the effects of failed airline services on the consumers' psychological process and their behavioral responses. Having different classifications from the previous studies, this study focuses on dividing important factors of airline services into search attributes(e.g. sale and procedure services, services concerning flight attendant, in-flight services) and experience attributes(e.g. flight services, collateral services). Using structural equation modeling, this study shows that the failure of service factors of the experience attributes provokes the feeling of disappointment with mediation effect of external attribution while the failure of service factors of search attributes provokes the feeling of regret with mediation effect of internal attribution. Finally, disappointment leads to consumers' complaint behavior while regret leads to consumers' switching behavior. Unlike previous studies, we show that when a service failure occurs, depending on each attribute, consumers feel negative emotions of disappointment or regret through different attribution processes and finally show different behavioral responses with an empirical analysis.

While ubiquitous healthcare (u-health) services were expected to propagate along with conventional healthcare services, recent progress indicated rather limited market acceptance. In this paper, we investigated the fundamental causes of why the consumer acceptance level of u-health services has been low. We draw upon innovation adoption theories to analyze the consumer readiness of the typical u-health services. The comparative analysis between innovative u-health services and conventional services was performed using analytic hierarchy process (AHP). Subsequently, policy and business implications including technological breakthrough insights were discussed based on the customer perspective comparative adoption analysis. The propositions captured through this study provide useful insight to further studies on u-health services.

B-ISDN is expected to be a main vehicle of future telecommunications. There has been a series fo studies on the demand and the market prospect of B-ISDN services. It is true, however, that they lacked some economic reality since the price of services has been overlooked which is a critical economic factor. In this study, we analyze some aspects of the tariff system of B-ISDN services. First, we explore and summarize the billing parameters of B-ISDN services from diverse characteristics of services and ATM network. These parameters are essential if the services are to be charged based on usage. Secondly, we discuss what factors be considered in the design fo B-ISDN services tariff systems from various points of view shch as traffic charactristics, information types and connection types, etc. The results of this study will offer fundamental insights in the design of B-ISDN service pricing scheme and provide reference for efficient services providing.

Demand for new information services is ever increasing as information technology advances in an unprecedented pace. Capabilities of information technology to overcome the time and space limitations enables efficient storage and processing of a large volume of data shared by many users in geographically dispersed areas. As the users ask for more useful information services, it is necessary to develop information services tp meet the needs of users. Enhancing information services is also necessary to cope actively with the pressures to open the information service is also necessary to cope actively with the pressures to open the information and telecommunications market as the level of Korean information services industry is still in its infancy. Value Added Network(VAN) services have a tremendous growth potential and its economic and social impact would be great as the information society matures. This study suggests a direction for the development of value added and new-media services based on the survey of individual and business users of information services.

Background and Objectives: The purpose of the study was to explore the attitude of workers toward a system of collaborative hospital practice between western and traditional Korean medicine, to identify factors influencing this attitude, and discuss the reasons socioeconomic groups' differences. Method: The data were collected with a questionnaire for this study from 14 April 2009 to 1 May 2009. Data were analyzed mainly via non-parametric statistics and logistic regressions utilising SPSS 17.0 (Statistical Package for the Social Sciences) to determine the workers' attitude about the hospital system and to predict factors contributing to positive attitudes. Results: A total of 1,260 workers working for large factories in Gwangju Metropolitan City. Findings confirmed that more than 40% of the workers show interest in the system and about 44% of the workers also express positive attitudes. Factors found to influence the workers' response included marital status, income level, health status, experience in complementary medicine services, the number of health care facilities' visit. Conclusions: The prospects to establish the system of collaborative hospital practice as reflected by the workers' view about the Korean health care service delivery system. Their attitudes toward the system differed among socioeconomic groups. Government and health care providers should identify the socioeconomic subgroups' demands and opinions in order to find and develop measures of integrating western and traditional Korean medicine in health care facilities.
