본 논문에서는 Home Phoneline Neworking Aliance(Home PNA) 장치에 연결된 많은 가입자들로부터 야기될수 있는 대역폭 서비스 불균형 현상을 해결하고 이 장비를 이용하는 가입자들을 관리하기 위한 웹 기반 Home PNA 장치 관리시스템을 구현하였다. Simple-Net-work Managment Protocol(SNMP) 를 탑대한 Home PNA장치를 관리하기 위해서 관리항목을 Muti Dewling Unit(MDU) 장비으 Management Information Base(MB)로 부터 추출한 MIB 오브젝트를 이용하여 시스템관리, 포트관리, 성능관리, 장애관리로 분류하였다. 시스템관리는 개별 MDU 장비에 대해 구성정보를 제공하고, 포트관리는 현재 가입되어 있는 가입자에 대한 현황정보를 제공하고 비인가 가입자에 대한 필터링을 수행한다 그리고 성능관리는 트렁크 라인과 가입자 라인의 트랙픽 정보를 제공한다. 마지막으로 장애관리는 예외 상황에 대한 장애로그 및 trap 메시지를 제공한다. 구현된 시스템의 운영성을 시험하기 위하여 실제 네트워크에서 그 동작성을 검증하였다.

This study is to clarify the actual conditions of the floor plan of middle and high schools in the rural area. Recently, many middle school and high school are remodeling the buildings and facilities based on the departmentalized classroom system. This study, through analyzing on 4 remodeling cases of middle and high schools in gyeongnam. This article discuses about the basic characteristics of the plan composition and the education programs of 4 schools. This study is showing the variation before and after remodeling and space organization types. The results of this study are summarized as follows; Home-room and home-base should be more faithfully. Various common space is needed to comfortable school life of students. In case of side corridor type plan, moving path is much needed. Sample schools took much more spaces of home base than before. This article discusses about the basic characteristics of the floor plan and the actual condition of the school facilities.

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.

The aim of this research is to study and develop enabling technologies for home healthcare device with ubiquitous network. The motivation of this paper is to enable healthcare in home, to development the device for smart home health care. To achieve the aim, we must develop the prototype platform based on home gateways, distributed context user interface based on UPnP and support for information sharing with high speed power line communication and mobile infra-structures. And IPv6 is the base technology of this platform. In this paper, we concern that physical health, mental health and medical emergencies is all of home healthcare. With the smart device, we evaluate the connectivity, automatic information extraction and private data exchange and event driven message. The result of this paper is demonstration of smart device for ubiquitous communication in a healthcare application such as patient monitoring device and several information services. In conclusion, home healthcare will support more healthy and easy living for a human.

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.

The specification of the Home Evolved NodeB (Home-eNB), which is a small base station designed for use in residential or small business environment, is currently ongoing in 3GPP LTE (Long Term Evolution) systems. One of the key requirements for its feasibility in the LTE system is the mobility management in the deployment of the numerous Home-eNBs and other 3GPP network. In this paper, we overview the characteristic of Home-eNB and also describe the mobility management issues and the related approaches in 3GPP LTE based Home-eNB systems.

This paper described some applications using Open GIS Component that was called MapBase. There were 4 applications : KSDI(Korea Spatial Data Infrastructure) funded by MOIC(Ministry of Information and Communication), National Plants Resource Management System supported by Korea Forest Service, 7-Underground Facilities Management System of Cheongju funded by MOCT(Ministry of Construction and Transportation), and National Disaster Management System supported by MOGAHA(Ministry of Government Administration and Home Affairs. Because they wanted to access heterogeneous spatial database, it was necessary to select MapBase as their base methodology. The main feature of MapBase was component S/W which provided the interoperability and reusability among GIS applications as well as non-GIS information system through common specification. In this paper, we showed some applications' architectures and functions to increase understanding MapBase. That would help you to make application using MapBase.

본 논문에서는 CMOS로 구현된 무선 홈 네트워크용 Base-Band Analog 수신단을 제안하였다. 제안된 수신단은 길버트 셀 형태의 믹서, Gm-C 형태의 Elliptic 6차 저역통과 필터, 그리고 6-bit A/D 변환기로 구성되어 있다. 제안한 수신단은 CMOS RF 단을 거친 작은 전력의 200㎒의 아날로그 신호와 PLL에서 나오는 큰 전력의 199㎒ 국부 발진 신호가 믹서에 인가되어 Base Band 신호를 생성해 낸다 이 신호는 낮은 주파수로부터 높은 주파수가지 분포되어 있는데 저역통과 필터를 거쳐 1㎒의 Base-Band 신호만을 추출해낸다. 이 1㎒의 신호는 다시 6-bit A/D 변환기를 거쳐 6-bit 디지털 code를 생성하여 DSP(Digital Signal Processing) 블록과 연결된다. 제작된 수신단은 0.25㎛ 1-poly 5-metal n-well CMOS 공정으로 제작되었으므로 유효 칩 면적은 200㎛ × 1400㎛ 이고, 2.5V의 전원전압에서 130㎽ 전력 소모를 나타내었다.

홈 네트워크 환경에서의 디바이스의 안전한 사용을 위해서는 인증이 필요하다. 이러한 인증은 크게 ID기반의 인증 방식과 인증서 기반의 인증방식이 있다, ID기반의 방식의 경우에는 멀티도메인 환경에 적용이 어렵고, 인증서 기반 방식의 경우에는 인증서를 탑재 및 저장하는 방식이 디바이스에 종속되어 있어, 소유권의 이전, 새로운 장비의 구매 등에 대한 사용자의 추가 설정이 요구된다. 그리고 두 가지 방식 모두 디바이스에 대한 개별적인 인증이 이루어져, 사용자가 요구하는 서비스 측면에서는 다수의 디바이스에 대한 잦은 인증으로 오버헤드가 존재한다. 이러한 문제를 해결하기 위하여 본 논문에서는 자바 카드에 디바이스 인증정보를 안전하게 저장 및 관리하는 기법을 제안하며 또한 서비스단위의 그룹기반의 디바이스 인증 기법을 사용하여 기존의 기법들에 비해 보다 향상된 수행속도를 보장한다.
