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.

The demand for multimedia streaming services is increasing rapidly. To meet this demand, there has been much research and many practical developments for providing multimedia services. A push-to-talk (PTT) service is one of the multimedia streaming services that have been deployed not only over IP multimedia subsystem (IMS) but also in peer-to-peer (P2P) overlay networks. The benefit of PTT has been demonstrated in the literature. However, the need for using PTT service in communication can be arbitrary among users, regardless what kind of PTT services they use. This demand does not support current PTT systems, so an expansion of PTT services still be limited. Moreover, the combination of PTT services in IMS and P2P networks will help operators to provide more scalable PTT services. Therefore, in this paper, we proposed a model to support PTT service interworking between IMS and P2P overlay networks. We also introduced our system design and some interworking service scenarios. We confirmed our architecture through implementation and testing.

Information services adopting RSS(Really Simple Syndication) is on an increase. It is replacing the existing email services. Information in the area of science and technology is of vast amount and various area and their life-cycle and service is complex. Institutions providing information of a single area are not faced with many obstacles in designing information services using RSS in acquiring a channel for the service. However, RSS service in the area of science and technology has to be more specific in designing and implementing the services. In this study, RSS is compared with other information service protocols, domestic and international trends in the area of RSS is analyzed to implement the RSS based Science and Technology information service system(STI-RSS) and its service.

There have been various studies being conducted to prepare for aging society due to the recent trend of rapid aging. The silver industry such as wellness, senior monitoring and support service, and emergency medical assistance services for the elderly is growing fast. However, due to economic problems, limited services are being provided. In addition, the problem of residence of elderly people and care of elderly patients are also becoming important issues to be solved. Aging in Place is emerging as an alternative to solve the problem of local deviation, controlled communication, and loss of self-sufficiency in the process of residents residing in the facility. In this paper, we propose IoT environment construction for ICT based Aging in Place information extension support. By building an IoT environment for Aging in Place support, users can be provided with services that can meet their needs in a familiar environment. The proposed method builds an environment that can be self-supporting based on the user's information and provides medical, transportation, and life support services for the elderly.

The purpose of this study is to type the necessary support services related to the employment of the elderly and to identify in-depth the relationship between the type of support services related to the employment of the elderly and factors that determine employment plans. Data provided by 182 small and medium-sized owners in Seoul A area were analyzed using latent profile analysis and logistic regression. As a result of the analysis, first, it was confirmed that the number of workers and the employment of the elderly were the factors that increased the probability of the elderly employment plans. Second, it was found that the "high-level group of necessary support services" is more likely to have plans to hire the elderly compared to other groups. Based on the results of the study, we would like to provide basic data regarding the direction of government support needed by private businesses to hire the elderly.

Currently, the housing supply rate exceeds 100%, and the penetration rate continues to increase. This housing supply rate is changing from quantitative supply-oriented to improving the quality of the residential environment in housing service policies. Despite the increase in the housing supply rate, practical access to the vulnerable class is still difficult and there are many areas that are insufficient to use housing services when necessary. In addition, the demand for residential services is increasing due to the expansion of the scope of the vulnerable class. In order to compensate for these problems, facilities and joint occupancy that cannot guarantee independent living are mainly established, although a supply plan is established for the vulnerable by expanding policies and support projects. This paper proposes an IoT environment-based housing support system for vulnerable groups to support housing services for vulnerable groups. The proposal system improves the quality of the residential environment and provides service-oriented support services. Through the proposal system, appropriate social participation opportunities can be provided by improving the quality of life of the vulnerable and supporting a residential environment where independent living is possible.

To reduce time to market for converged services, the service provider needs to combine external services and internal processes together, and IT architecture for converged services has to support it. Service Oriented Architecture (SOA) enables the development of a converged service by combining external services and internal processes effectively. However, it is difficult for the existing SOA methods to support the evolution of a converged service, even though the service which consists of the converged service changes over time. In this paper, we argue that a method for profile-based dynamic service binding is required to support evolution of converged services. In order to identify requirements for the proposed method, a business scenario with a smart athletic equipment is given. We then present the concept and architecture of the method for profile-based dynamic service binding to meet the identified requirements. We also demonstrate a prototype implementation for evaluating the proposed method.

The purchase of business services is a growing activity among finns but with little appreciation that the purchase of a service requires a modification of the decision process developed for the purchase of material goods. A taxonomy for purchasing business services is developed to create a matrix with company involvement and focus of service as dimensions. Business services are classified according to their focus on three aspects of the finn: property, people, and core business. Business services are also classified according to the degree of company involvement: high company involvement and low company involvement. A number of propositions are formulated based on insights derived from this taxonomy. The taxonomy results in six business service cells: facility support, equipment support, employee support, employee development, core business facilitator, and professional. Implications for managers considering a purchase in each category are explored. This study tests the research hypotheses delineated from the classification model and the purchasing process of business services. The strategic implications are suggested based on the findings for each cell of the classification model. This study concludes with a research agenda for further studies.

The purpose of this study was to identify the social networks used by the rural elderly and to analyze the effects of these social networks on the need for life services. The research subjects were 1,000 people aged 65 years and over living in the rural areas of Korea. Among the total 1,000 respondents, 979 elderly who have children were included in this study. The data were analyzed using frequency analysis, descriptive statistics, and multiple regression analysis. The results of this study were as follows. First, the frequency of contact with friends/neighbors was higher than that of children, whereas the social support of children was higher than that of friends/neighbors(excluding physical support). Second, the rate of use of home services and the elderly welfare center was very low. Promotion, a minimum cost burden, convenient transportation (circulation bus operation, etc.), and the provision of visiting services are examples of ways to be using them much more. Third, the elderly who do not live with their children have a higher need for life services. As well unlike the elderly who live with their children, in the case of the elderly who do not live with their children, the necessity for life services was influenced not only by their children but also by the relationship with their friends/neighbors and by home services. This implies that comprehensive social networks are important for the elderly who do not live with their children. Therefore, it is necessary to activate the social support of the community as well as of children and friends/neighbors.
