In this paper, we propose a Digital Living Network Alliance (DLNA) proxy system, to provide services for accessing and sharing various DLNA-based media contents which are distributed over his/her or other's home facilities via home network or internet. The proposed system based on DLNA[1] and SIP Notification mechanism[2] so that data such as contents can be transferred from home network consisted with private IP from outside public IP networks.

The purpose of this study is to investigate the etymological change of 'home economics' and to suggest the future research direction of home economics. For this purpose, 'oikonomia'-that was used by aristotle-was analyzed and the process of the change of the term 'oikonomia' after modern society was considered. according to the results of this study, it is known that economic perspective has been enhanced in study in home living. the enhancement of the economic perspective in grasping home resulted in the limit of understanding of the meaning and nature of home. It was suggested that we should take more interest in 'economy' on the basis of 'oikonomia' than in 'home economics' which is based o 'economics', philosophical study rather than empirical study these subjects should be adequate.

Home-Automation which it automates as connection home by network gives human beings to many conveniences but there is problem must solve. Rightly it is an illegal infiltration against the information transmission and a joint ownership of information home appliance machinery and tools. Especially design of Home Automation is necessary for Information Security because the vulnerability is exposed when it is connecting on the mobile communication terminal and the home appliance machinery and tools. In this research, we're going to help to function and efficiency improvement of Korean Home-Automation by Security Design and proposal for a research and development of Korean Home-Automation.

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 questionnaire survey was carried out to analyze the difference of consumers perception on apparel products presented in catalog, cable TV home shopping program, and internet shopping site. 676 men and 728 women participated in this survey and they were members of catalog shopping or cable TV home shopping companies or netizen. The results of this study show that the shoppers perception on apparel home shopping differed by the direct shopping media that they frequently utilize and by their demographic characteristics. The cable TV home shoppers had higher reliability on product quality than the shoppers using paper catalog or the internet shoppers. The cable TV home shopping members perceived that the apparel products available in cable TV home shopping were diverse and the information about the products was sufficient to decide purchase. The married women tend to think that the TV home shopping program provides diverse apparel products in the aspects of color, design, size and the information about the materials including fabric.

In this paper, for the development of a safe and reliable DC home appliance suitable for DC home power supply system, we classified a number of inherent problems with help of the comparative analysis of existing AC and new DC home appliance. Several new technical problems of DC home appliances are mainly linked to the DC transient state. Among them, this paper concentrates on start-up inrush current problem, uni-polarity problem, and heavy DC load control problem. And to address these problems, we herein present an implementation of robust safety circuits for DC home appliances. Specifically, we investigate several multi-circuit countermeasures and select the best among them through comparative evaluation, based on theoretical, simulational, and experimental results.

The purpose of this study is to identify the types of professional teaching practice of Home Economics teachers who are working at Korean secondary school for changing their professional teaching practice and developing home economics curriculum. A mail questionnaire, Professional Teaching Practice(PTP) was used to survey randomly selected 525 Home Economics teachers. The professional teaching practices examined were customary-instrumental, interactive and reflective practices. Customary-instrumental practice was the predominant type of professional teaching practice used by Home Economics teachers. About 26% of the teachers used reflective practice, and 14.67% used interactive practice. Only the number of students was significantly related to their professional teaching practices. Five influential factors on teaching practices identified by Home Economics teachers emerged in the following order: examination-centered educational system, lack of class hours, lack of resource materials and facilities, demands from the Ministry of Education, school administrators, or parents, and large class sizes.

This paper describes the design and implementation of a wireless home network system using Home Network Control Protocol (HNCP) called the wireless HNCP home network system. For wireless interfaces of HNCP, IEEE 802.11b and IEEE 802.15.4 standard protocols are considered. With the implementation of the wireless HNCP home network system, a simple analysis about coexistence between IEEE 802.11b and IEEE 802.15.4 is achieved. Through the implemented wireless HNCP home network system and the analytical results about the coexistence between both two different wireless protocols, the feasibility of the wireless HNCP home network system is shown.

The purpose in this study is to identify beliefs about curriculum orientation of Korean secondary school home economics teachers for the development of home economics curriculum and the change of their curriculum orientation. The curriculum orientations explored were academic rationalism, technical, cognitive process, personal relevance, and social reconstruction. A mail questionnaire, Individual Curriculum Orientation Profile (ICOP), was used to survey randomly selected 525 home economics teachers. Home economics teachers agreed with the cognitive process as their predominant curriculum orientation. The second predominant type with which home economics teachers agreed most was personal relevance orientation. Home economics teachers’age, major, college type, and teaching years were significantly related to the academic rationalism curriculum orientation, and the college type for bachelor’s degree was significantly related to the technical curriculum orientation. Age and major in master’s degree were significantly related to the social reconstruction curriculum orientation.

This study investigates the efficacy and coping strategies of Home Economics teachers in secondary schools. Data were collected from 75 Home Economics teachers via a mailed survey and from 282 Home Economics teachers via an online survey. Descriptive statistics including frequency, percentage, average, and standard deviation; in addition, the ANOVA, t-test, multiple linear regression, and correlation results were reported using SPSS statistics 17.0. The results were as follows: First, the average Home Economics teachers efficacy level was 3.82 out of 5-point Likert scale. The efficacy level of learning assistance was the highest. The composite efficacy of Home Economics teachers showed a significant difference depending on the major. Second, the averages of the positive and negative coping strategy level of Home Economics teachers were 3.54 and 2.03, respectively. Third, the efficacy of instructional strategy out of the five components of efficacy was the most influential to the positive coping strategy. There was no significant relationship between teacher efficacy and the negative strategy.
