The supply of Korean housing has met the demand thoughout the fourth quarter of the twentieth century, and demographic, social and economic changes have been entailed. All the circumstances became a significant foundation to develop digital homes. This study was designed to find out the residents' current use of and needs for digital services, and the interview with three housewives residing in a recently developed digital home was conducted. The three households used most of the digital services, and favored cellular phone, as the main device to use digital functions, since it's small and easy to carry out and operate. It was noticed that the use and preference of digital services was likely to be explained by the lifecycle each household and the lifestyles of an individual. The participants didn't use the webpage of the digital home since the information contained in the web site wasn't quite useful. Also the interviewees perceived that digital home brings many conveniences and benefits. Currently, the main constraints for further development of digital home in Korea are affordability and the establishment of a variety of life scenarios from real situations.

Network industry is complex combined with various fields of industry, such as communication, broadcast, construction, and home appliances. Moreover, it's fairly lucrative since the growth industry makes lots of added values, interacting with the others.The network industry, usually called 'Ubiquitous', connects some home appliances and makes an integrated system that you can use them with whenever and wherever. A demand for network security, however, has skyrocketed due to the relatively low safety. It's been expected that the market of home security is going to be grown up nearly 30 percent every year. Recently, analog surveilance cameras have been replaced with digital ones, and they will be providing stronger security services taking advantage of mutual interaction with related industies. In this paper, a mobile monitoring system for home security is proposed, which makes it possible to supervise all home appliances wherever you're, using the conventional wired/wireless network infra.

This study is intended to forecast changes in Ubiquitous technology-based residential environment since the digital revolution so as to suggest the direction of furniture design in the near future. Among Ubiquitous technologies, the intelligent digital technology applied to a residential environment is defined as "Smart Digital Technology." Ministry of Commerce, Industry and Energy named the residential environment where such technology is applied "Smart Home." Smart Home is strategically creating intelligent residential environment where interactivity is made between human, furniture and residential environment, based on home automation, home network and intelligent sensor technology. Smart furniture is based on strategic characteristics of smart home. Its convergence with IT equipments is being made. Largely, smart furniture has three characteristics as below: First, smart furniture provides users with information on home management, health management, education and fashion. not just functioning as storage space. Second, smart furniture that is a new lifestyle pattern will suggest a new aesthetic standard based on unsettled shapes and innovative structure. Finally, it gives convenience to users intelligently. Namely, smart furniture, "intelligent informative furniture", will be suggested as a new paradigm.

This study was intended to suggest the design guidelines of digital home on the basis of digital-related human behavior. In order to achieve this, what and how often internet was used in the home, how living pattern and space usage was changing according to digitalization were examined and lastly, the design guidelines of digital home based on these findings were suggested. The subjects were 400 housewives who lived In 85m'-sized housing unit of the new apartment complex in Busan. They were average age of 38 and their eldest children were in the stage of elementary schooling or preschooling. Many of them had relatively high educational level and middle income level. The results of the study were as follows; 1) The respondents used internet more frequently for information searching, children's education, and Internet shopping. Therefore, it would be desirable to divide zoning of housing unit into space for routine activities, space for working, and for cultural activities. 2) Digitalization changed human living pattern like follows; it reduced time of shopping, information searching, banking, and going out. Also, it increased time of spending alone, watching movie, and playing game. Therefore, digital home should be designed to facilitate social Interaction between family members, cultural and recreational activities, and indoor or outdoor exercise within each housing unit or in apartment complex.

Since the late 20th century, digital technology has changed our environment in many ways. The representative advanced homes today embed digital facilities such as a sensor infrastructure, a networking system, and ubiquitous display. In this point of view, this study was intended to define the apartment residents' diverse needs for digital home design. The subjects are 400 wives who live in Busan. The findings are as follows; (1) The factors of the housing activities are extracted as 'guest hosting,' 'family entertaining,' 'digital network,' 'daily domestic affair,' 'non-daily domestic affair,' 'media using,' and 'bathing & exercising' activities. (2) The 'digital network activities' occurred more frequently in the households with non-employed wife and preschool children, and with employed wife and preschool and elementary school children. (3) The factors of the digital home system were extracted as 'safety & maintenance,' 'health & convenience,' 'educational & housekeeping,' and 'cultural & entertaining' systems. (4) The needs of non-employed wives for the safety & maintenance and the educational & housekeeping systems are varied by family life cycle and wife age. While, the needs of employed wives for the educational & housekeeping and the culture & entertaining systems are varied by dwelling-size and wife age.

최근 디지털 방송 분야는 네트웍, 디지털 켄텐츠, 그리고 멀티미디어 등의 다양한 첨단 기술에 의하여 우리나라의 정보화를 가속시키고 산업적으로도 경쟁력의 중심이 되는 역할을 하여 산업 성장의 기반이 되고 있다. 본 논문에서는 가정 내의 케이블 TV망을 기반으로 방송신호와 동일한 고품질 RF 신호를 출력하여 각 방의 디지털 TV에서 별도의 장치 없이 디지털 TV 수신이 가능하도록 한 가정용 디지털 방송 녹화 및 송출을 위한 홈 스트림 스테이션을 개발하였다. 홈 스트림 스테이션은 방송 중에서 사용자가 지정된 방송 신호를 수신하여 저장하고 있다가 원하는 시간에 녹화된 프로그램을 RF신호로 바꾸어서 가정내의 케이블 TV망에 송출한다. 그러면 각방에 있는 디지털 TV에서는 방송사업자가 제공하는 방송신호와 동일하게 수신 채널만 선택하여 주면 스트림 스테이션에 저장되어 있는 방송프로그램을 볼 수 있다. 또한 국내 IP-STB(Set Top Box)에도 가정내의 네트워크를 활용하여 고품질의 디지털 방송 컨텐츠를 제공할 수 있도록 하기 위하여 본 기술개발의 스트림 스테이션에서는 LAN을 통한 네트워크 인페이스를 지원하도록 개발하였다.

WUSB is a new technology which combines the speed and the security of wired USB with the easy use of wireless technology. In this paper, GUI for WUSB is designed and implemented to show the connectivity and contents of the WUSB devices. Also, the proposed GUI shows the log window while content transfers occur between the host and device. The proposed GUI can be used for various wireless technologies which provide wireless function with existing USB hosts and devices.

A digital home is a ubiquitous environment that is expected to be realized in the near future. All information appliances in a house are connected to each other through wired and/or wireless home networks. Authenticated user can access the various services provided by the digital home, and the access is not restricted by equipment, time, or location. The technologies that form the digital home can be grouped into two categories: wired networking technologies and wireless networking technologies. For the purpose of ubiquitous environments, wireless-networks offer suitable and seamless high-quality services. A wireless LAN can be created simply by equipping a single access point. For that reason, the cost of establishing such a network is low and using it is easy. Of course, there is an exciting new wireless technology. It is the Ultra Wide Band (UWB). However, it is not enough to bring wireless convenience, although offering a broad range of high-speed data transfer capabilities, Because of unstable. Thus, of the wireless-networking systems, we focus on the wireless LAN. We quantitatively analyze its capabilities. The dynamic and adaptive wireless LAN provides a foundation for the evolution toward the next generation of wireless and adaptive networks. The difference between wired LAN and wireless LAN in upload and download rates is small. Although the wireless LAN experiences a greater loss rate than the wired LAN, the difference is minimal. We conclude that a wireless LAN is suitable for use in an apartment environment.
