The home network is generally separated from the Internet, as it is made up of a private network due to security issues and the lack of IPv4 addresses space. Also, a user may want to move from a terminal to another terminal connected in the home network during communicating with people outside the home. In this case, people connected in the Internet, or another home network could not communicate the user at the home. These limitations prevent a SIP-capable device connected in the home network from communicating with another SIP-capable device connected in the Internet or the outside of the home network. To overcome the limitations, This paper proposes the Adaptive SIP Application Server System as a software architecture that a user inside of the home can communicate with people outside of the home when the home is composed of a private IP-based network. Moreover, the proposed architecture provides the session mobility that allows the user to maintain a media session even if changing the terminal inside of the home during the session established. The proposed system was implemented over a home server device which acts functionality as a connection point for transmitting IP packets between a home network and the Internet.

The networked home is connected to the external world using a high speed network. The devices inside the house are connected using a wired and wireless network. Acquiring the user data is an essential step for designing the user interface in user centered design. In networked home, the numbers of use cases are exponentially increased because connected use cases are considered. Because the user data for networked home are too complicated, they are acquired and analyzed by a structured methodology. We surveyed 40 people to acquire the context data home and analyzed by 5W1H (Who, Where, What, When, Why, How). We established a framework for the user data using tasks, user, time, space, objects and environment. The data for home context was structured by our framework. This framework makes simple the home context and is helpful for user interface design in home network.

The purpose of this study is to investigate the home connected praise and encouragement program which it affects the interpersonal relationships and subjective well-being of elementary children. To achieve this purpose, 58 fifth grade students were measured based on the interpersonal relationships and subjective well-being scale. Then 29 students were placed in the experimental group while the other 29 children were placed in the control group. The experimental group participated in home connected praise and encouragement program, the control group didn't. The quantitative analysis results verifying the effects of the program were as follows: The experimental group treated by the home connected praise and encouragement program showed significant improvement in interpersonal relationships and subjective well-being compared to the control group. Follows are results from qualitative analysis. First, children have increased positive personal relations with companion, parents, teacher, and improved closeness with family by the home connected praise and encouragement program. Second, children have increased edification of self-confidence, satisfaction in school and home by them. These results supported our hypothesis that the home connected praise and encouragement program effectively improved interpersonal relationships and subjective well-being of elementary school children.

Recently, various home appliances are inter connected in wired/wireless network to provide a single service, but their interfaces are not uniformly integrated. In order to get a service in such an environment, users have to figure out how to control each appliance and the way of combining its functions with others. Even worse to the users, many buttons are barely used to control the complicated functions of the appliances on the remote controllers, and controllers have very similar shapes in each other. In this paper, based on the definitions of a task as a unit of services provided in the environment of multi-connected appliances, we propose a markup language for home appliances, called HAML (Home Appliance Markup Language), for generating task-based user interfaces to help controlling multi-connected appliances as one pleases. The proposed method generates interfaces by gathering the buttons frequently used and necessary for tasks, and provides automatic settings of multi-connected appliances. The proposed method is verified with an analysis of scenarios and usability tests.

This study examines a multivariate model of the effect of life events and transitions, intrafamily strain, marital adjustment, and appraisal on family well-being across the family system types. Data from 356 families were analysed SAS program. The result show that life events had no direct on family well-being but they intensified intrafamily strain. Family strain, in turn, negatively affected marital adjustment in flexible-connected families and structured-seperated families and perceived well-being in flexible-seperared, flexible-connected and structured-seperated families. marital adjustment were positively related to well-being in flexible-connected families. In flexible-connected families, marital adjustment seems to buffer the effect of intrafamily stain on well-being. The result also suggested that a combination of cohesion and adaptability level may explain differencies in the family's response to de4mands.

Home-Network is an integrated network of the PC and all electric home appliances in the home so that they can communicate with each other. In the 21th century, here are various technology for Home Network environment such as HomePNA, IEEE 1394, Ethernet Lan and Bluetooth. For Home Network construction, generally, the standard series interface 'RS232' is used to make communication possible between electric home appliances. However Home network using RS232 has a problem. That is, All machines have to be connected to each other with RS232 using Point-to-Point mode. In this case, the system becomes complicated because we have to use circuits as much as there are machines and increased expenses. To improve this problem, In this thesis, designed home network using RS422 Multi-drop mode serial communication and controled it with embedded linux system. And connected RS422 with motors and sensors using PIC to make the home network virtual environment.
