Recently, T-Commerce is emerging to provide new services, with the proliferation of digital broadcasting services. However, T-Commerce market and TV home shopping market are being classified as a legal policy on other markets, such as regulated in the service of live broadcasts. The factor that has inhibited activation T-Commerce related to the lack of appropriate institutions and legal systems in the market, despite the environment with the digital broadcasting service is being spread. We were performed conjoint analysis. For this analysis, we select attributes as a quality attractive factors that significantly affects the satisfaction of TV based shopping customers through previous studies. The results showed that the TV-based shopping customers are important to think 'Responsive', 'Playfulness', 'Live broadcast', 'Convenience' and 'Bidirectional' in the order. The 'Responsive' and 'Live broadcast' of such attributes are served as possible only in TV home shopping, because these attributes don't service due to legal and institutional regulations in T-commerce market. The cluster analysis result also showed that TV shopping consumers are more important to think 'Responsive', 'Playfulness', 'Live broadcast' than 'Convenience' and 'Bidirectional', except one of the classification clusters. If real-time broadcast service is impossible because of the legal and institutional regulations, it seems to require the expansion of the services linked the terrestrial broadcasting to the activating T-Commerce market.

This study introduces trends on silver care implemented with the fourth industrial revolution technology, and discusses the use of digital technology for elderly health and rehabilitation by reviewing relevant literature to examine and present directions for future digital-based silver care commercialization. First, health smart home, which is a smart residential service available through digital technology or IT technology that supports independent living in your home, is available. Second, there are technical services using artificial intelligence(AI) and robots. Robots based on advanced intelligence can serve as an assistant for the health and rehabilitation of senior citizens by supporting services that enable the daily lives of senior, checking their health conditions, and high-quality medical care. For the commercialization of these silver care systems, information and services appropriate to the current situation, such as the physical ability and health status of the elderly, should be provided, and it would be desirable to gradually expand the use of essential technology to reflect the needs of the elderly in use so that the digital alienated.

Compared to corporation and government networks, home devices and services connected in a home networks has security threats because of the use of various wired and wireless network, middleware and protocol in digital home environment, a restricted system resource of home information appliances and the users who do not care about security. So security is critical element to provide secure services in a home network environments. In this paper we design the access control system based on RBAC to offer secure home network services.

In this paper, we design and implement the UHSNS-DRM(Ubi-Home Smart Multimedia Streaming-Digital Right Management) in Ubi-Home. The proposed system support flexible distribution platform for digital content copyright protection and management in Ubi-Home. This system also can provide multimedia streaming service to authorized users who are using PC, STB, PDA, and Portable Device, etc. Furthermore, we adopt concept of domain authentication and it help to improve the efficiency of license management for all devices in Ubi-Home. We design user's location recognition algorithm in order to provide intelligent services. Of course, this algorithm is applied for the proposed system. Start after striking space key 2 times.

Purpose: This study was done to evaluate the operating status of community-based home health center for revitalization of the centers. Method: In this study performance data including organization plan and service utilization plan were evaluated according process theory. Target of evaluation was the community-based home health care center. Results: The vulnerable part of the organization was the information system and financial resources. The home health center introduced PDA (Personal Digital Assistants) in 2005, however home health care nurses did not make full use of it. This service received full support from Seoul city and local government and there were no other sources of income. The vulnerable part of service utilization was service expansion and standardization due to vulnerability of organizational aspects. Conclusions: The home health care center provides high quality services to underprivileged people. In the future, these services should be provided with equity for continuous health care for this population.

This is a user experience study of factors that should be considered in designing home appliances experience service. Untact services are emerging, but the development of home appliances sector is in early stage. Based on the six factors of Stephen P. Anderson's Creating Pleasurable Interface Model, this study conducted surveys, 1:1 in-depth interviews, and participation observations to measure and analyze user experience. In this study, I compared 4060s and 2030s's user experience in that the untact services raise the digital alienation among middle-senior-aged. As a result, there were significant differences between the two, including the opposite satisfaction in terms of reliable, usable and pleasurable factors. I hope that this study will be of strategic help in designing future home appliance experience services.

In these days, the trends of home networking system is implementation of easily configured system with home security of emergency alarm and visitor verification services. In this paper, we implemented push server system based on Arduino of open source physical computation platform to verify visitors for the homes without home networking services. In the suggested system, visitor verification is performed in and out of home, and home access security of the system could be constructed with low-cost price by use of windows push server system and smart devices with alarm operation in corresponding to not allowed access trying.

The massive traffic interferences in the wireless home IoT provides the reason for packet losses, and it degrades the QoS (Quality of Service) and throughput on the home network. This paper propose a new adaptive traffic interference control system, ATICS, for enhancing QoS and throughput for IoT services as detecting a traffic process and non-traffic process in the wireless home network. The proposed system control the traffic interferences as distinguishing the short-term traffic process and long-term traffic process by traffic characteristics in wireless home networks. The simulation results shows that the proposed scheme have more efficient traffic control performance than the other schemes.

Recently the interest in digital home services and its related technology has increased rapidly. Multimedia data transmission between digital devices that are connected to home network is essential function. This paper presents the design and implementation of multimedia streaming system based on IEEE1394 in Linux environment. The key features of proposed system are as follows. First, it can transmit and receive not only DV format data but also MPEG2-TS format data through IEEE1394 bus. Second, it uses device drivers that handling IEEE1394 and IEC61883 protocol transparently to reduce the complexity of communication program. Third, it applied capacity adaptation technique considering various specifications of PCs to get smooth streaming for HD data. These characteristics are tested on testbed of IEEE1394 based home network. The proposed media streaming technique can be used as a home media sever in Linux environment.

The recent efforts in academia and industry represent a paradigm shift that will extend the IoT from the home environment so that it is interoperable with the Internet of Vehicles (IoV). IoV is a special kind of IoT. It allows to connect between vehicle and things located in infrastructure. Furthermore, IoV enable to create new intelligent services through collaboration with existing various services such as smart city and connected home. In this paper, we develop a service in order to realize IoV. To this end, we design a novel vehicle service platform which could automatical controlling the IoT device according to drivers' voice. To show practical usability of our proposed platform, we develop a prototype service could be call car-to-thing (C2T). We expect that our proposed platform could eventually contribute to realizing IoV.
