So far the study of digital home has mainly been made up of the network technology and the sorority system, but the application to consider the discriminatory characteristics of the individual family members has been interested in comparison with the necessity. The system proposed in this study is to get the information of the internal users through the access-controlling system. The controller offers the discriminatory environment by activating the database of the internal users and controls the sub-system of the home-network. The suggested system can automatically offer the discriminatory environment among the family members by limiting TV programs or channels according to the users' age, by offering other internet environment according to the users, by putting restrictions on telephone numbers, or by restricting the settling right of the home-shopping companies.

홈 네트워킹이 이슈화 되면서 많은 기능들을 내장한 홈 네트워크 제품이 개발되어지고 또한 판매되고 있다. 이러한 기능의 추가로 인하여 홈 네트워크 제품들의 소비전력 및 대기전력 또한 증가하고 있다. 본 고에서는 이러한 정보가전기기가 정상동작을 하지 않는 대기동작시의 전력소모량을 줄이기 위하여 기존에 많이 사용하였던 플라이백구조의 SMPS에 디지털 제어블럭 및 보조 SMPS를 이용하여 대기전력 소모량이 적은 디지털제어 전원공급시스템을 구현해 보았다. 이 시스템은 통신기능을 지원하도록 설계함으로써 네트워크 모뎀과의 통신을 통해 외부에서의 원격제어 및 모니터링이 가능하다.

고속 데이터 통신 시장은 이미 대규모 시장을 형성하고 있으며, 이에 발맞추어 다양한 형태의 서비스(오락, 멀티미디어 통화, VoD, EoD, IPTV 등)가 상용화되었거나 상용화를 눈앞에 두고 있는 실정에 있다. 이러한 서비스들은 네트워크화된 다양한 단말장치를 통해 이루어지게 되는데, 서비스가 고도화되면 될수록 관련 단말장치의 설치나 유지보수의 복잡도가 증가되며, 이는 곧 서비스 제공자와 서비스 사용자에게 각각 원가상승과 서비스 사용료의 상승으로 이어 지게 된다. 따라서 단말장치의 설치비나 유지보수비 절감이 사업의 성패를 좌우할 수 있으며, 이를 위한 다양한 노력들이 진행 중에 있다. 본 고에서는 이러한 노력들의 일환으로 진행되고 있는 몇 가지 표준들에 대해 서술하고, 이들을 기반으로 하는 디지털 홈 관리방안에 대해 논하고자 한다.

Because of governmental regulations, large-scale discount stores are trying to find a new way that can expand a market size. Homeplus virtual store has received attention from the other companies, because virtual store can access 24 hours and be unfettered by governmental regulations. The purpose of the study is to review performance and strategies of Homeplus virtual store as well as the cause of the failure of imitators. To do this, we can find key indicators of success of virtual store.

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.

Home computers that are connected to the Internet are under attack and need to be secured. That process is relatively well understood, even though we do not have perfect solutions today and probably never will. Meanwhile, however, the home computing environment is evolving into a home network of multiple devices, which will also need to be secured. We have little experience with these new home networks and much research needs to be done in this area. This paper gives a view of the requirements and some of the techniques available for securing home network.

최근 가정 내 디지털 기기 간 네트워크 가능성이 현실화되면서 관련 산업과 기술에 대한 관심이 고조되고 있다. 또한 최근 들어 컴퓨터의 보급이 확산되어 2대 이상 보유가구가 늘어나고, 점점 더 많은 전자기기를 소유하면서 각각의 장치들을 한데 묶어 서로 연결하며, 인터넷 접속을 통해 더욱 편리함과 부가가치를 창출하고자 하는 욕구가 증대되고 있다. 이에 본 연구는 댁내에 안전한 삶을 누릴 수 있도록 홈 디지털 기기간의 통신 방법의 설계 및 제어할 수 있도록 구현하고, 임베디드 장비를 이용하여 보안 기기와 통신할 수 있는 홈 서버를 개발한다. 댁내, 외 어디에서나 집안의 현재 상황을 관리, 제어 및 모니터링이 가능하도록 설계하였다.

New paradigm of the 21st is 'Ubiquitous'. And great changes arises from the digital environment and technology. Also, our living environments are changing very rapidly. Because of rapid developments, we didn't have enough time to examine our current situation. So we had to look around the current living spaces. The main purpose of this research was to know about the home network service and environmental context in our living spaces and to explore the outlook in the forseeable future. To search them, four recent digital home exhibition houses were examined. The findings showed that many kinds of common network systems were suggested and were acted in limited spaces. And when we examined the environmental context, we found most of the instruments were installed fixed ones or integrated information appliances. Therefore, the plan of digital home needs to consider environmental context and the combination of residents and living spaces.

The home network environment can be defined as a network environment, connecting digital home devices such as computer systems, digital appliances, and mobile devices. In this kind of home network environments, there will be numerous local/remote interactions to monitor and control the home network devices and the home gateway. Such an environment may result in communication bottleneck. By applying the mobile agents that can migrate among the computing devices autonomously and work on behalf of the user, remote interactions and network traffics can be reduced enormously. The mobile agent authentication is necessary to apply mobile agent concept to the home network environments, as a prerequisite technology for authorization or access control to the home network devices and resources. The existing mobile agent systems have mainly used the public key based authentication scheme, which is not suitable to the home network environments, composed of digital devices of limited computation capability. In this paper, we propose a shared key based mobile agent authentication scheme for single home domain and expand the scheme to multiple domain environments with the public key based authentication scheme. Application of the shared key encryption scheme to the single domain mobile agent authentication enables to authenticate the mobile agent with less overhead than the public key based authentication scheme.
