In this paper, we have designed a Home Networking System using an embedded linux board. The system based on the World-Wide-Web is composed of three parts - a Server, a Client and a Simulator. The Home Networking Server is built in an embedded board using an embedded linux kernel. A web-server and Home Networking Server Seryice Demon programming with a Jaya-Language is included in the board. Clients can connect to the server board using a web-browser in the desktop computer, PDA or any other machines which include a web-browser. For this purpose, we made the client program using a Java-Applet. So, the clients who connect to the server for the control of the applications, download the class-file and execute the client-program in the web-browser. So, the clients don't need any other programs to control the applications from a remote place. The size of server board is very small (86.3$\times$74mm), which makes it very useful not only for the Home-Networking-System but also in many other fields, e.g., embedded robot control system, etc. Using an embedded board instead of a desktop computer is good for a simple network environment and it occupies only a small space to make the system.

Since home network system is usually set up based on the built-in system inside home at the time of construction, it has a difficulty in being compatible with new devices after construction. In this paper, we propose DBS(Dynamic Binding System) that can make links effectively among the devices located in inside and outside of home networks. Implementation of the DBS is based on the ZigBee's binding in WPAN(Wireless Personal Area Network). For this research, we constructed the system consisting of home server that contains proxy server and location server, devices inside home in which tinyOS is embedded, and mobile device that is an emulator. The communication inside home is done by IEEE 802.15.4 protocol and the communication between servers and mobile devices outside home is done by TCP/IP protocol. Regardless of device's address format, the DBS facilitates a link among the devices located inside and outside of home networks. And, introducing a new device into home network can be recognized easily by exchanging messages between devices.

Under the penetration of smartphones equipped with a variety of features grows globally, the efficient using of a variety of functions of smartphones has been increased. In accordance with this trend, a lot of researches on the remote control method using the smart phone for consumer products in home networks. Input methods of the current smpartphoes are typically button-based inputs through touching. The button input methods are inconvenient for people who are not familiar touch. Therefore, the researches on the different input schemes to replace the touch methods are required. In this paper, we propose a gesture based input method to replace the touch-sensitive input that of the existing smartphone applications, and a way to apply it to home networks. The proposed method uses three-axis acceleration sensor which is built into smatphones, and it also defines six kinds of gestures patterns that may be applied to home network systems by measuring the recognition rates.

With a rapidly aging population, the proportion of elderly households with low income has been increasing. Despite the poor housing environment, it is not easy to improve their housing environment due to the high cost of modification. However, as many elderly want to keep living in their current houses, it is urgent to improve their housing environment. The purpose of this study was to develop the guidelines on home modification for low-income elderly. This study set the scope of home modification categories through literature analysis in advance to develop the guidelines. Based on the literature analysis and small group workshops, the primary and secondary guidelines were derived and a total of 169 final guidelines were produced based on the scope of home modification categories. Those guidelines were composed of the categories by space, divided into mandatory and recommended by details. Those guidelines proposed in this study were classified and composed under the objective standards, so that they were systemic and objective based on the verification of experts. They are considered to get closer to the user's demand on the basis of the demand of low income elderly for home modification and the improvement categories under the system to support home modification for low income elderly at home and abroad. In addition, as the standards to apply each guideline, separated into mandatory and recommended, was suggested, those guidelines may help expand the scope of improvement under the economic conditions for home modification.

Recently, there has been an increasing need for long-term care and comprehensive health care services in community settings. The Ministry of Health and Welfare introduced the Hospital-Based Home Nursing Care Program in 2000. Before this initiative, there was a Home Nursing Demonstration Center, affiliated with the Seoul Nurse Association, had offered home nursing services with the financial support from the local government. since 1993, the Center's nursing staff has been engaged in a general hospital in an effort to provide home nursing care services within Korea's health care system. The purpose of this study was to analyze and identify characteristics of community-based home nursing care supplied by a community-based home nursing team engaged in a general hospital. Also. visit nursing care services provided by public health centers were evaluated in terms of accessibility and supply versus demand, to enhance the accessibility of low-income patients living in Seoul to home nursing care services. Data were collected from home nursing insurance reimbursement claims submitted by the community-based home nursing care team from March 1 to October 30 in 2001 and a questionnaire survey on home-visit nursing services of 25 public health centers in Seoul. The subjects consisted of 197 patients and 12 public health centers. The result were as follows. First, medical institution's community-based home nursing care program was better in technical quality than health-center-based home-visit nursing care. In addition. the pattern of the subject patients was similar to that of hospital-based home nursing care program. Second, there was a high demand for community-based home nursing care while only a small number of home-visiting nurses served at public health centers in Seoul. As a result, many patients could not receive adequate care. Finally, we suggest that community-based home nursing care program should be introduced in the national health system to meet the at-home care needs of severely ill low-income patients. Furthermore, to better utilize home nursing and visit-nursing care resources and offer continued care for patients in community settings, an efficient referral network should be built among related institutions. This would require improvement of reimbursement system and amendment of the law related to health insurance system and community-based home nursing care services.
