We have developed the convergence system that can control an appliance under ubiquitous circumstance. The system can display the GPS information received from the satellite, several control signal and mobile phone signal. In order to display the information between phone and the PC, we can control program command.

When mobile node moves into the different IP address area, the mobile node can be set the proper environment parameters automatically by DHCP. If we extend the DHCP option field to support the roles of home agent and foreign agent in mobile IP protocol, mobile node can perform the foreign address registration process of mobile IP protocol when DHCP IP environment is achieved automatically, too. DHCP is supplied in the PC with a series of Windows NT. This paper proposes and implements the functional blocks of extended DHCP nodes and this enables the DHCP node have a role of mobile IP agents without another protocol functional blocks.

Typically internal mobile LCD display modules are connected to the mobile product baseband PCB with flexible printed circuit board equipped with board-to-board connector. This solution has a drawback of limiting the product concept work to certain solutions that are based on connector size, location, flexible PCB length, bending, etc. in the display module. Also flexible printed circuit board based solutions are not completely optimized from reliability point of view, causing flex circuit board breakings. For the external displays in the PC or Home entertainment market, the cable solution is too expensive and resource demanding. The wireless solution has obvious advantages over reliability, low cost and flexibility. This paper describes a wireless audio-visual interface solution.

This study examined the effects of mother's support and peer acceptance on children's domain specific self-esteem and the moderating effects of best friend's support. The subjects were 272 $4^{th}$ and 349 $8^{th}$ grader in Chin-ju. Data were analyzed by the SAS/PC+ program, including Cronbach's ${\alpha}$, Pearson's correlation, multiple regression and two-way ANOVA. Findings were that peer acceptance had a higher influence on academic-general self, peer-related self, physical-appearance self, personality self and physical-competence self than did mother's support. Mother's support had a higher influence on home self than did peer acceptance. Best friend's support and mother's support interacted with children's physical-appearance self and physical-competence self. Best friend's support and peer acceptance interacted with student's peer-related self.

In recent days, as the efficiency of electronic home applications become higher, that of the driving AC motor become higher. On this reason, the demand fir high capacity coil firming machine is increasing. Since the coil forming is not simply related with the only capacity of hydraulic cylinder, the development of a newer coil firming machine which has new filming mechanism new driving method, new filming tool, and new specification is required. In this paper, the virtual prototype which have new mechanism is developed. This prototype is tested and experimented on PC with the same condition as actual. The results from the virtual experiment is applied to the actual design process.

This study includes noise automatic inspection system for washing machine auto-transmission one of modern home necessary. We effort to find and certificate sound noisesource by sound power and sound intensity, and apply to frequency analysis in vibration related sound noise. Still more we have been studying to data acquisition and programming for MS VisualBasic version 5.0. System component is below. 1) Pentium PC for data acquisition. 2) DSO for noise acquisition. 3) S/W for comparison and decision. 4) I/F Board for data communication. Wave form data through the DSO are converting to ASCII code data. The ASCII code through binary converting S/W are to be decision fitness or the badness comparison S/W. Finally, we will making noise monitoring system and automatic inspection system.

Demographic transition drives changes in consumer demand for food products. This study examines how rising incomes and population trends affect spending on food purchased for home. The objective of this study is to characterize the relationships between selected socio-demographic factors and food selection among South Korean households. Panel data from Rural Development Administration (RDA) in South Korea in 2010 was used (n=971). Household food purchases were classified into one of the five food groups from Composition of Foods of RDA. Multiple regression analysis was used to analyze the effects of household size and income based on the expenditure share on each food group. All statistical analyses were performed using SAS/ PC version 9.3. Results show that household socio- demographic characteristics have a strong influence on food purchasing, with the purchase of vegetables and fruit, and processed food and pre-packaged being particularly sensitive.

홈네트워크(Home Network)는 일반 가정의 PC 및 주변기기, 정보기기, 디지털 가전제품 등을 단일 프로토콜로 제어해 가정내 디지털 기기간에 정보전달과 정보공유를 자유롭게 한다는 개념이다. 최근 정보통신 서비스가 대용량 고속화 및 멀티미디어화되고 일반 주거 지역으로의 유입 및 네트워크 설비 구축이 활성화되면서 기존의 전화망에 의한 단순 음성통신 또는 데이터 통신 환경과는 다른시설 패러다임이 이루어지고 있다. 이에 본 논문에서는 먼저 홈네트워크를 구성하기 위한 유무선 기술에 대하여 조사 분석, 홈네트워크 선로설비 구성시 요구되는 기자재중 케이블에 대하여 조사하였으며 이를 바탕으로 홈네트워크를 구축하기 위한 댁내배선 설계에 대하여 작성하였다.

A distributed healthcare monitoring system prototype for clinical and trauma patients was developed, using wireless sensor network node. The proposed system aimed to measure various vital physiological health parameters like ECG and body temperature of patients and elderly persons, and transfer his/her health status wirelessly in Ad-hoc network to remote base station which was connected to doctor's PDA/PC or to a hospital's main Server using wireless sensor node. The system also aims to save the cost of healthcare facility for patients and the operating power of the system because sensor network is deployed widely and the distance from sensor to base station was shorter than in general centralized system. The wireless data communication will follow IEEE 802.15.4 frequency communication with ad-hoc routing thus enabling every motes attached to patients, to form a wireless data network to send data to base-station, providing mobility and convenience to the users in home environment.

This Paper describes the system configuration and implementation method of an IMPRES (Interactive Multimedia exPRESS) terminal. The terminal is developed in the form of a PC add-on board that is called MINIBA (Media and Network Interface Board Assembly). IMPRESS is a communication service platform that support various interactive multimedia services. The main objectives of developing IMPRESS are to implement DAVIC compliant services platform to verify DAVIC specification and to support testing environment. Currently IMPRESS terminal provides MPEG-2 quality movies on demand, switched video broadcasting, and home-shopping service to the service user, based on the ATM network.
