The convergence of broadcasting and telecommunication services is being accelerated by broadband networks, digital broadcasting and Web2.0. This paper describes the definition and service characteristics of IPTV as a representative of broadcasting and telecommunication convergence services. Especially, the changes of infrastructure and technology for IPTV2.0 are addressed in terms of the service features of mobility, intelligence and participation. IPTV2.0 shall be characterized by the open IPTV service based on Web2.0 and the mobile IPTV service over the heterogeneous networks employing various wireless/wired access technologies. The IP Multimedia Subsystem (IMS) and Service Delivery Platform (SDP) technologies are increasingly considered to support the personalization and openness. The mobility management technology is being evolved to provide QoS-guaranteed mobile communication services to users at anytime and anywhere. IPTV2.0 services and platforms are also anticipated to be core components to achieve knowledge-based ubiquitous society. IPTV2.0 contents are required to be integrated with the enhanced metadata to efficiently support search, selection, convergence and delivery of the contents. Moreover, those contents shall be enhanced to provide the scalable services which is adaptable to the network status and user preferences. Therefore, the networking technologies for IPTV2.0 should tightly cooperate with application services and adaptive contents.

It is expected that the next generation mobile communication system will be a service-driven developed system capable to realize the human-centric mobile convergence services. and it is different from the technology-driven development approach of the second and the third generation mobile communication systems. As a preliminary research work on such service-driven system development approach for the next generation mobile communication system. we developed the scenario based service analysis process (2SAP) framework to derive core service technologies and functionalities. In this paper. we propose the next generation mobile convergence service business model creation methodology based on research results of the 2SAP framework. To achieve this goal, we first establish a service model contains several components such as infrastructures. operations. and provision of services that are indispensible for providing next generation mobile services. Then, the next generation mobile services and its corresponding business models can be created by adding service and value flows to the developed service model after defining necessary components of business model including actors, their relationships, and roles.

This study identifies the concept of a digital convergence paradigm, which deals with the relationship among convergence and consumer participation, digital contents services, and the culture of consumption (web 2.0). This research was conducted using a quantitative method involving focus group interviews (FGI) and literature reviews. This research examines the relationship between convergence and consumer participation and the adoption of a concept of "convergence culture", which is categorized as "collective intelligence" and "intellectual community participation". The role of the consumer has changed from one of a "consuming consumer" to that of a "collaborating consumer" and finally to the concept of a consumers as the originator of a new consumption culture. In the study, the consumption culture of web participants indicated the characteristics of funology, self-expression, life-catching, quick-tempered, immersion(arousal), sharing culture, multitasking, and cyber justice. The recognition level of networking on the "digital convergence" of the consumer was identified as that of the combination of IT(information technology); product and multi-services or alliance of industry groups(telecom, broadband, IPTV service); or the use of one source with multiple devices.

The social welfare facilities are trusted by the government for the development of appropriate welfare services and their delivery systems. They aim to provide people with professional social welfare services and, for this purpose, they develop ways to effectively operate facilities and to deliver the services efficiently. So far, the five consecutive evaluations based on the Social Services Act have suggested the effective and systematic ways of operating social welfare facilities. Through these efforts, they established an important basis for the balanced development and further advancement of social welfare facilities. Nevertheless, people have continually pointed out problems concerning the evaluation system of social welfare facilities. Accordingly, these problems have the necessity of investigation for reformed directions by means of effective control and evaluation system for the operation of social welfare facilities. Therefore, this study aims to suggest convergence models for improving the social welfare facilities evaluation system.

Convergence is now the trend of knowledge information society. Information technology and knowledge transfer are main sources of convergence. There are many articles which studied outcomes of convergence while there are few articles that try to study the process of convergence. The purpose of this study is to investigate how convergence is dynamically formalized. For the analysis, we used Institutional Analysis and Development(IAD) framework from the point of convergence. IAD framework could synthetically study the origin and the process of convergence. We investigated the case of sillicon valley whether or not dynamics of ICT convergence could be explicable by IAD framework. The results shows that ICT technology and knowledge could be the enabler for the formation of convergence. ICT technology accelerates convergence and knowledge convergence from information converge different technologies and industries. This article provides a theoretical foundation for future research to analyze dynamics of ICT convergence by the IAD framework. For the future work, it is recommended that a study is to be empirically analyzed the dynamics of ICT convergence.
