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. Those technologies will be developed to construct the ubiquitous content service platform considering the evolution of networks and various converged services.

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.

사회복지시설은 지역주민의 복지욕구에 적합한 서비스의 자원개발과 전달체계를 국가로부터 위임받아 국민에게 전문적인 사회복지서비스 제공을 위해 시설의 합리적이고 효율적인 시설운영과 효과적인 서비스전달 등에 대한 사회적 책임의식을 가진다. 지금까지 사회복지사업법 규정에 의한 제5차에 걸친 평가는 사회복지시설 운영의 효율성과 책임성을 제고하는 동시에 합리적이고 체계적인 운영방향을 제시하여 사회복지시설의 균형적 발전과 선진화를 위한 중요한 토대를 마련하였다. 그러나 사회복지시설 평가의 문제점에 대해서도 지속적으로 제기되어 온 것도 사실이다. 따라서 본 연구에서는 사회복지시설에 대한 사회적 요구에 부응할 수 있는 평가체계가 갖추어야 할 기준과 개선방안을 도출함으로써 시설이용자들의 복지를 통한 삶의 질을 향상시킬 수 있는 융합모형을 제시하고자 한다.

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.

멀티미디어 방송통신 융합서비스는 TV 디바이스에 다양한 인터넷 및 미디어 관련 응용 서비스들을 구동하기 위한 플랫폼 기술을 접목한 새로운 형태의 방송통신 융합서비스이다. 기존의 TV 기술에 임베디드 OS를 탑재하고, 다양한 스마트 응용 서비스를 지원할 수 있도록 하기 위해 OS 위에서 다양한 플랫폼 등을 탑재한 형태의 진화된 TV 기술이라고 할 수 있다. 이렇게 융합된 서비스는 Open IPTV, Smart TV, 모바일 IPTV, N-스크린 등의 멀티미디어 방송통신 융합 신규 서비스가 국내 서비스 3사를 주축으로 활발히 서비스 되고 있다. 하지만 서비스 제공을 위해 인터넷에 접속하고 소프트웨어를 사용하기 때문에 인터넷과 소프트웨어의 취약성을 내제하고 있다. 이러한 취약성은 심각한 보안 사고로 이어질 수 있다. 따라서 본 논문에서는 기존의 보안 위협들과 취약성들을 바탕으로 멀티미디어 방송 서비스 환경에서 발생 가능한 보안 위협들을 도출하였고, 실제로 위협이 보안 사고 등으로 이어질 수 있는지 보안 위협에 대한 검증을 모의 해킹을 통해 실시하였다. 이러한 결과를 이용하여 멀티미디어 방송 융합통신 융합서비스 환경에서의 대응 방안을 제시하였다.

The wide deployment of wireless access technologies and the integration of various access network interfaces into a single terminal, allows mobile end-users to be always connected to the IP network, and to use those interface simultaneously. In this paper the CTE provides various access network interfaces capabilities, allowing reception of data over multiple service providers with different characteristics. Considerations for multiple network and service provider environments are regarded as essential for the successful deployment of convergence services in Next Generation Network (NGN). Event Driven Service (EDS) is regarded as a typical convergence service converging different functions of multiple service providers. This paper first describes the deployment model of NGN convergence services for multiple service provider environments. It also covers the service scenario of EDS, a convergence service for multiple service provider environments in NGN. Multiple provider environments stimulates the unified identifier management, namely ubiquitous identification (U-ID), to enable users to be provided convergence services without awareness of multiple provides. Then the designed structure and procedures of U-ID based EDS are given. Finally, the implementation results tested on Korea Advanced Research Network (KOREN) are described.

Information technology convergence has been recognized one of the key drivers in the industry perspective. Korea government established IT convergence policy in 2008 and has been implementing it to the core industry such as automotive, shipbuilding and defense industries. This research analyzes various IT convergence issues based on an operation of defense IT convergence center, one of the industry IT convergence centers. Defense IT convergence issues are as follows : the methods for introducing rapid changing IT to military area, rapid deployment procedures of verified commercial technologies and products, regulations for using of domestic software promotion and so on. We define the concept of defense IT convergence and propose the framework and processes for applying IT to our defense sector as one of industries. Also, we establish various business models in the military perspective using defense IT convergence framework. In this paper, we focus the development of defense IT convergence through the alignment of national IT convergence policy and propose various business models established through operating a defense IT convergence center.
