The purpose of this study is to review current home-based work study and identify factors associated with the choice of home-based work. Home-based work as an alternative form of employment is being sought today by both workers and business. The information age with its empasis on the recoding and transfer of information along with the technology of telectommuting has increased potential for and attention to home-based work. Home-based work seems to have several advantages particulary for women who carry the double burden of household work and paid work. The reduction in traffic congestion and demand of fossil fuels that accompanies the elimination of commuting has also been seen as a important social benifit. Home-base work has potential that can improve women's labor force participation. Further study is needed to evaluate home-based work and critical advice to current and prospect workers.

This paper presents the design of a USB home controller and a home control system that specially is focused on controlling home appliances as a part of home network systems, the implementation of the USB device access class in an OSGi service platform and a home security system as an application. Designed USB home controllers are able to control various home appliances. They can be used not only to control big home appliances like a boiler but also to control small home appliances like a toaster because they are low-cost solutions. The USB home controller supports real time control using the interrupt transfer of the USB specification. And It is easy to use by homemakers who have no technical knowledge of the system because they just plug and unplug it in a home server then it automatically joins and leaves a home control system. This technique is based on hot-plug and the USB Device Access class in an OSGi Service Platform. The USB Device Access class supports the coordination of automatic detection and attachment of the USB home controller on an OSGi Service Platform, and it downloads and installs device drivers on demand. For an application, we implemented and tested a home security system using two USB home controllers and a CDMA module.

Our society is rapidly digitalizing. The effects of his digitalization are very diverse and one of them is that our living environments are changing. Many routine places which certain activities have been taken places are changing. For example, home office, education at home using internet, home shopping, internet banking, and so on. These facts cause the home to be extended and digitalized. That is, as our living patterns are changing, the housing needs are also changing. The purpose of this study is to graspe the digital related housing needs of the residents and suggest the directions of the digital home design. The subjects were 400 housewives who lived in 85m2 sized multi-family houses in Busan. They were relatively young in their age, had high education level, and middle income. On the base of their demands, the digital home designed as follows would be desirable: 1) safe and secure design and digital system, 2) design to improve residents' health and encourge family interaction, 3) human, warm, and soft interior mood, 4) the space composition different from the existing one.

Authentication is needed to use safe devices in the home network environment. In this authentication, there are an ID base form and Certification base form. In case of an ID base form, it is difficult to apply to the multi domain environment and in case of an Certification base form, because the way that contains and stores the certificate demand on devices, additional setting of the user is needed for transfer of ownership and purchase of new devices, and more. Because both ways attend an individual authentication for devices, the ways exist overhead as the frequent authentication for a lot of devices in service aspects of user needs. To arrange these problems, in this paper, the authentication information of devices can be securely stored and managed in the java card and a processing time of the authentication could be improved better then the existing technique by authenticating a group of service.
