The result verification that determines correctness for the work results calculated in each PC is one of the most important issues in PC grid environments. In this literature, voting-based and trust-based schemes have been mainly used to guarantee the correctness of work results. However, these schemes suffer from both waste of resource utilization and high computation delay because they can not effectively cope with dynamic computational environments. To overcome these shortcomings, we introduce the distribution information of PC resources based on credibility and availability into result verification phase. Using this information, we propose a new result verification scheme, which can determine the correctness of work results by each PC resources' credibility and cope with the dynamic changing environments by each PC resources' availability. To demonstrate the efficiency of our result verification scheme, we evaluate the performance of our scheme from the viewpoints of turnaround time and resource utilization, utilizing resource distribution information in the Korea@Home that is a representative PC grid system in domestic. We also compare the performance of our scheme with that of other ones.

The objective of this study is to provide new direction on house design in consideration of the user's life pattern. To this end, pc usage status at home, demand for pc using space, and requirements for pc room interior were analyzed. A survey was taken by parents and the SPSS win.10 was applied for analysis. The survey was conducted for 2 months, starting May 2004 to see the computer usage at home, demand and satisfaction for the computer's room. The results of this study were as follows; The oldest son or daughter in a family was the main user of the computer, posting 71%. 42percent of respondents said they used the pc in their son's and daughter's room while 36% answered living room. It reflects that the whole family want to use the pc in their sharing room, or for their children's convenience. Currently, inconvenience of space-related constraints for using the pc was not that high, which possibly stems from a lack of awareness of inconvenience in using the pc. However, the need for furniture and space for refreshment was suggested. Through this study, it is expected that new housing designs need to be made to reflect these requirements into interior design and building plan for user's convenience.

The objective of this study is to provide new direction on house design in consideration of the PC users' life pattern. This study found that PC use present conditions at home, demand for PC using space, and requirements for PC using area were analyzed. A survey was taken by 1108 residences, and the SPSS win.10 was applied for analysis. The survey was conducted to see the computer usage at home, demand and satisfaction for the PC using space. The results of this study were as follows; forty-seven percent of respondents said they used the PC in son's and daughter's room while 36.8% answered living room. It reflects that the whole family want to use the PC in the same area, or for their children's convenience. Users' consciousness was analyzed four factor, which were 'physical inconvenience:'satisfactions in PC position', 'inconvenience caused by narrowness', 'notion of privacy'. PC users' consciousness had significant differences in the satisfaction by PC users' characteristic and housing characteristic. It was to be classified that the PC use space into several pattern according to furniture arrangement, and channel pattern had the highest satisfaction among those pattern. Through this study, it is expected that new housing designs need to be made to reflect lese requirements into interior design and house plan for PC user's needs.

This paper analyzes performance measures of a Bluetooth_based mobile home network system. The home network system consists of terminals with Bluetooth interfaces, access points (AP), a home PC, and a gateway A mobile host in wireless terminals uses Mobile IP for supporting the mobility This paper considers four types of data traffic, which are new connection traffic, handoff traffic, Internet data traffic, and control data traffic and suggests a queueing system model of the home network system, where the AP and the home PC are modeled as M/G/1 with four priority queues and the gateway is modeled as M/G/1 with a single queue The generation rate and service time of individual traffic influence their performance measures. Based ell the suggested model, we propose the elapsed time of data traffic in terms of the number of cells, the number of Home PCs, arrival rates of four types of traffic and the service rates of AP/Home PCs/Gateway To analyze influences on the elapsed time with respect to arrival rate of four types of traffic, some examples are given.

The implementation of home network systems In ubiquitous computing environments requires middleware that provides a method to control and operate home appliance devices. The Universal Plug and Play (UPnP), which is based on the IPv4 protocol and running on a PC, consists of UPnP devices that provide relevant services and control points that control the devices. However, It is inappropriate to Implement UPnP devices on a PC, since the implementation on a PC requires much space and electrical power. In this paper, a small embedded home network device equipped with UPnP middleware is implemented on an embedded GNU/Linux system running on an ARM9 platform, in order to deal with such problems.

디지털 홈 시대의 도약으로 가정용 TV의 기능과 그 역할이 확대되면서 Digital TV(DTV)가 새로운 가전기기의 하나로 등장하게 되었다. DTV를 통한 디지털 데이터 방송뿐 아니라 웹 컨텐츠의 다양한 활용이 가능하게 되면서 기존의 PC 환경과는 다른 DTV 환경에 적합한 새로운 컨텐츠 표현 규격이 필요해졌다. 이에 다수의 디지털 데이터 방송 표준 단체들이 DTV를 위한 디지털 데이터 방송용 컨텐츠 표현 규격을 제시하고 있고, DTV가 등장하기 이전부터 TV와 웹의 접목 기술을 위한 W3C의 활동도 있어왔다. 또한 양방향 TV 서비스 또는 웹 TV 서비스를 제공하는 방법으로 자체적인 컨텐츠 표현 규격을 정의하고 브라우저 등의 프로그램을 통해서 시청자들에게 TV에 특화된 다양한 웹 컨텐츠를 제공하고 있다. 이에 본 논문에서는 현재까지 제시되어 온 DTV 또는 TV환경을 위한 컨텐츠 표현 규격들을 다양한 관점에서 비교 검토해보고자 한다. 또한 DTV가 가지는 특징들을 살펴봄으로써 TV와 다르고 또한 PC와도 다른 DTV만의 특성을 반영할 수 있는 컨텐츠 표현 방법을 제시하고자 한다. 이를 통해서 DTV 시장 활성화의 선두 위치에 있는 국내에서 DTV 용 컨텐츠의 표현 규격에 대한 보완 및 발전 방향을 숙고하고, 세계적으로도 앞서가는 인터넷 서비스 시장이 DTV를 통해서 안방에서 보다 효율적이고 간편한 방법으로 다양한 계층의 사용자에게로 확대될 수 있는 계기를 마련하고자 한다.
