Rapid expansion of digital convergence, involving services and technologies from different areas that are combining to create new forms of products or services. Digital convergence itself is changing from technology-based to content-based, to include the convergence of different types of contents as well as contents of the same kind. In line with this trend, vigorous researches are being done to combine various formats and types of academic contents to create new services. In this paper, we examine cases of connection and convergence among different types of academic contents and analyze its characteristics, as well as the pros and cons. We especially focus on CLICK, KISTI's model of connection and convergence among different types of contents, to introduce a special feature of convergence platforms, difficulties involved and their solutions, and researches to be conducted in the future.

Due to the advancements in the capabilities of smart devices and home networks, we are able to easily access multimedia contents stored in a home server. In this paper, we present a wireless media content sharing mechanism for home networks that utilizes UPnP-based DLNA technology. We also present a novel Peer-to-Peer content sharing system that is able to operate on the client as well as server. Our system supports multiple push/pull services simultaneously via a multi-thread technique, and our intuitive user interface facilitates ease of use. Future studies would explore the feasibility of implementing our system in a multi-hop environment or providing a community-wide service.

Electronic reference service was defined as reference service designed for remote users and identified by a specific link from a library' website. This study examined whether academic libraries deliver web-based electronic reference services to remote users. Particularly, four types of electronic bulletin board services, free bulletin board, FAQ, Q＆A and reference question-response service were measured in terms of 8 types of questions and 12 contents of questions. The result showed that there was few differences among 4 services. Guidelines for effective use of electronic bulletin board services in academic libraries were suggested: standardization of service names, easy access to menu services, definition of each menu, search function for contents and standard web forms.

Real-time streaming services over the Internet have increased with the explosive growth of the various mobile platforms, with a focus on smart phones, and the demand for them is growing. In addition, the bandwidth occupied by the streaming services over the Internet had already surpassed 50% in 2010. Because of the shortage of network bandwidth for multimedia services traffic, restrictions on quality and capacity will become more and more serious. CCN is a future Internet architecture that improves how existing host-based Internet architecture handles content-oriented structure, but it is designed for the transmission of general contents and is not suitable for transmitting real-time streaming contents. In this paper, we focus on the inefficient aspects of CCN and propose a hierarchical grade-based scheme for real-time service for a more efficient environment in real-time streaming services. Experiments have shown better performance in terms of bandwidth, network load, and reliability.

As the influence of social networking services across the societies becomes greatly higher, many of the domestic agencies are trying to communicate with users through the introduction of social networking services. In this paper, we present a reliable exhibition-related contents recommendation service to combine social networking service concept with the customized contents recommendation method we previously proposed. The proposed service may effectively and reliably recommend its users exhibition-related contents by exploiting their relationships in the social networks compared with the existing ones.

This paper describes the personal video recorder-based approach to realise enhanced services for interactive programmes on digital television. So far it is very difficult that most of interactive programmes included the vast quantities of contents, whatsoever it is data-broadcasting or HD-ready, are broadcasted on digital television via the current set-top box. Furthermore it was not possible to envisage until IPTV has been appeared. Even though IPTV makes possible for streaming the interactive services via high-speed broadband, it is not easy to receive the tremendous contents with interactivity through the current set-top box in a single effort. In this paper it suggests the effective solution to resolve the download dilemma for providing the interactive services on digital television by employing the set-top box fitted with the personal video recorder.

This study aimed to explore the effect of the intimacy with social workers on the use of social welfare services of marriage-based female immigrants. Also, this study verified the effect of the quantity of the welfare service-related information as a mediated variable on the use of social welfare services. For this purpose, this study collected data from a total of 304 immigrant women married to Korean men living in City of Busan, City of Ulsan, and South Gyeongsang Province, and the data was analysed by SPSS 21. As the result of study, the intimacy with social workers had significant influences on the use of social welfare services of the married immigrant women. The results also showed that the intimacy with social workers contributed to the quantity of the welfare service-related information. Based on these results, implications of the important roles of social workers and the directions of their effective roles for the marriage based female immigrants to use the social welfare services were suggested.

Although message services in mobile environments provide real-time transfer of various contents such as text, multimedia and location, they can't provide dynamic message services based on analysis of message contents. This paper proposes "message as a service" concept and presents the design methodology for a message platform. The message in this paper is composed of the data part and template part which is in charge of view and functional logic of contents. In addition, two parts of a message are transferred separately. If a terminal device stores message templates, message platform can transfer data part only and thus network traffic can be reduced. Besides an efficient network utilization, we can dynamically update message view and its functional logic by modifying templates.

This study attempted to suggest a strategy for providing rural community tourism information services using smartphones. Study subjects were men and women among 300 who currently use smartphones. Empirical analysis was done on 249 of the 300 subjects. Upon verification of the effect factors of adults' smartphone usage and rural community tourism information services usage, they were both statistically significant based on Ajzen's(1991) Theory of planned behavior. Hence, behavior, subjective norms, perceived behavioral control should be augmented in order to increase smartphone usage behavior to access rural community tourism information services. Especially, behavioral intent and usage behavior was increased proportionately to behavioral control. We suggested that plans to provide applications free of charge and building a social consensus on utilizing rural community tourism information are important in achieving such status.

As digital convergence and mobile services evolve, personalization becomes one of the most important factors attracting customers. Personalization means functions offering individually customized services with relevant contents using information on individual preferences. This sort of personalized services has attracted great attention of a large part of online firms. One of representative services of such personalized services is a mobile widget service. In this study, we identified seven antecedents affecting the quality of personalized mobile widget services and empirically investigated which antecedent has a significant effect of the quality of personalized mobile widget services. In addition we carried out empirical investigation into the effect of the quality of personalized mobile widget service on user satisfaction and trust. As a result of this research, we revealed that seven variables including information services affected components of personalized services, and usefulness and perceived benefit as components of personalized services affected user trust and satisfaction for personalized services.
