  • For the usage of the different standard technology among DRM vendors, the DRM technologies in today could not guarantee the interoperability between the digital contents and digital devices. While users have been guaranteed the protection of contents, they have to put up with the limitation and inconvenience. The Superdistribution methods that InterTrust has proposed is the content distribution technology which is possible to use the content only by the user authentication with the license regardless of the acquisition of the DRM contents. However, it need a additional license with re-authentication from DRM server when the original contents need to be moved to other devices from the own device. In this paper, to reduce the inconveniences of re-authentication and re-issue procedures of the license and continually to protect the rights of contents on the offline, we propose the DRM system that creates domain between home devices and enable users to freely transfer contents with the domain.

  • The purpose of this study was to develop lesson plans and teaching materials applying practical reasoning instruction for the 7th home economics curriculum content, and to test the effect of practical reasoning instruction on morality of middle school students. This study is a quasi-experimental research with a pretest-posttest design. Practical reasoning instruction for experimental group and traditionally lecture oriented instruction for comparison group were input, and tested the statistical differences between two groups before and after the treatment. The subjects for this study were 8th grade students of a middle school located in Kwangju city. Two classes of 76 students homogeneous in characteristics and academic record for each experimental and comparison group were assigned. Instrument used for this study was a revised moral indicator, that was developed by KEDI(2001). Spss/win for 10.0 statistics program was used for analysis of data. ANCOVA was done for testing statistical difference between pretest and posttest of experiment group and comparison group. Result of study which showed statistically significant difference between groups were:1. Virtue of "responsibility for words and deeds"(from 3.22 to 3.61 for experimental group and from 3.27 to 3.26 for comparison group) in domain of responsibility and cooperation, and virtue of "punctuality"(from 3.59 to 3.76 for experimental group and from 3.41 to 3.28 for comparison group) in domain of trustworthiness, 2. Virtue of "conversation etiquette"(from 3.47 to 3.67 for experimental group and from 3.28 to 3.31 for comparison group) in domain of caring for others, 3. Virtue of "forgiveness other′s mistakes"(from 3.32 to 3.65 for experimental group and from 3.33 to 3.25 for comparison group) in domain of kindness, concession, forgiveness, and virtue of "volunteering activity"(from 2.89 to 3.71 for experimental group and from 3.36 to 3.45 for comparison group) in domain of compassion and service, 4. Virtue of "equip the convenient facility for handicapped"(from 4.19 to 4.29 for experimental group and from 4.17 to 3.91 for comparison group) in domain of equality and human rights, virtue of "recovering selfness for own community"(from 2.34 to 2.79 for experimental group and from 2.14 to 2.29 for comparison group), virtue of "opposing way of accomplishing purpose by an means"(from 3.27 to 3.31 for experimental group and from 3.47 to 3.05 for comparison group), virtue of "opposing election of considering acquaintance"(from 3.35 to 3.56 for experimental group and from 3.12 to 3.14 for comparison group) in domain of fairness, and virtue of "eradication of military force or violence among countries"(from 3.49 to 3.57 for experimental group and from 3.38 to 3.05 for comparison group) in domain of love for humanity. The morality of experimental group was improved more than that of comparison group in all of above items. From the results of this study, following conclusion was drawn. Practical reasoning instruction in home economics is effective in raising students′ virtue and value of responsibility in words and deeds, trustworthiness in punctuality, courtesy of not interrupting conversation, forgiveness of other′s mistakes, volunteering activity, equity for handicapped, fairness opposing selfness for own community, fairness opposing way of accomplishing purpose by all means, fairness opposing election of considering acquaintance, and love for humanity opposing war.

  • This study aims to provide lesson plans that can simultaneously achieve both the learning goals of the 'Human Development & Family' domain of the 2015 revised Technology & Home Economics curriculum and the Sustainable Development Goals. Four steps including analysis, design, development, and evaluation and revision were followed. In the analysis step, the 'Changing Families and Healthy Families' unit was selected as it is relevant to the nine subgoals of the SDGs. In the design step, three sessions were planned with a problem-solving project approach. In the development step, three lesson plans for each session, individual and group activity worksheets for students, and guidelines for teachers were constructed. In the evaluation and revision step, criteria for evaluating the lesson plans were developed reflecting both the goals of the Home Economic curriculum and the SDGs. The validity of the lesson plans was reviewed by a panel of experts. Then, the revised lesson plans were finalized. This study provides an illustrative example of the lesson plans in the secondary education context that can be used to achieve the learning goals of the Home Economic curriculum and the Sustainable Development Goals at the same time.

  • The main purpose of this study is to examine the concepts appeared on research and provide future research directions in field of child health nursing. 205 studies of the total 318 studies had been analyzed first for the concepts of the client domain and this time 113 studies were analyzed for the practice, the client-nurse and the environmental domain in nursing. The practice domain includes mentalistitic, enactment, knowledge utilization, role related phenomenon, the client-nurse domain includes touch, communication, interaction phenomenon, and the environmental domain includes physical, social, symbolic environment. All were originally published between 1990 and 2000 in Korea. An analysis of concepts for this study was used the metaparadigm framework for nursing proposed by H. S. Kim(2000). 1. 103 studies belonged to the practice domain. Among them, 56(54%) studies used concepts related to enactment phenomenon like education(21.4%), giving information(7.1%), breast feeding(5.4%), caring(5.4%), airway suction(5.4%), nonnutritive sucking(5.4%). 44(43%) studies used concepts related to knowledge utilization like program development and evaluation of smoking, mother-infant interaction, home health nursing, obesity management. And only 3(3%) studies used role related concepts like quality of nursing, direction of health education, contents of child health nursing education. 2. Only 2(0.006%) studies belonged to the client-nurse domain. One concept is empathy in communication phenomenon and the other concept is role conflict in interaction phenomenon. 3. 8(0.02%) studies belonged to the environmental domain. Among them, 3 studies related to physical environment like space, noise and 5 studies related to social environment like social support, home environment. But the concept of symbolic environment was not used. The findings of this study provide the evidence that research related to the client-nurse domain and the environmental domain should be conducted actively to improve the practice of child health nursing. So that the research in field of child health nursing should be dealt with the concepts of four domains to develop knowledge systematically.

  • The home network has been revitalized due to the emergence of the high-speed broadband network and explosive increases of the home network services. Especially multicast based high-definition (HD) IPTV service is on high demand from both Internet service provider (ISP) and users. In order to provide high quality HD IPTV service without packet loss and delay, the ISP utilizes various network QoS mechanisms. Due to the misleading fact, that the home gateway is considered as an end terminal in terms of the ISP's viewpoint, the ISPs can not guarantee the end-to-end QoS within the scope of the current home network architecture. Therefore, an independent QoS guaranteed mechanism should be considered within the home network domain. As the home gateway manages both private home and public access network within the home network, we propose and implement a novel QoS mechanism for the multicast based HD IPTV service over the home gateway. In order to provide QoS guaranteed HD IPTV service, the proposed mechanism classifies the packets, manages home network bandwidth resources, and executes call admission control using the channel join message. Also, we utilize layer 2 multicast packet forwarding scheme to improve the overall performance of the home network services. Through the experiments of implementing the multicast based HD IPTV services, we will verify the efficiency of the proposed mechanism.

  • Mobile computing environment makes it possible for computing activities to be maintained during movement even if a user changes its network point of attachment. Mobile IP is a standard protocol designed to be used in such mobile computing environment. However, Mobile IP has a drawback to incur a lot of handoff delays and waste network resources, since CoA(Care of Address) registration packets need to go through a HA(Home Agent) first whenever a mobile node moves. To solve this long-standing problem, this paper proposes a new scheme that, for infra-domain movement, efficiently performs local handoff without notifying the HA Specifically, based on the notion of load balance, the proposed scheme allows every FA(Foreign Agent) in a domain to become the root FA(also known as domain FA) dynamically, thus distributing the registration task into many other foreign agents. The dynamic root assignment through load balancing ultimately leads to fast network response due to less frequent transmission of registration packets.

  • Purpose: The purpose of this study was to analyze functional independence and need for home nursing care in stroke patients. Method: This was a descriptive study. The subjects comprised 117 stroke patients who were supposed to discharge in less than a week. The instruments used for this study were the functional independence measure(FIM) and the need assessment for home nursing care of stroke patients. The data were analyzed using frequency, mean, t-test, ANOVA, and Pearson correlation coefficient. Results: Pearson correlation analysis revealed that there were negative correlations between subcategories of the FIM and the need for home nursing care in stroke patients. Especially, in case of the subjects who recorded lower scores at self-care they showed higher needs for home nursing care in the domain of physical problem and rehabilitation. Conclusion: For the operation of the home nursing care, the protocol for home nursing care is needed to the stroke patients living at home. The FIM instrument is recommended as a useful scale in order to assess the disability for the stroke patients and the need for home nursing care because this one has correlation with the scale of need for home nursing care.

  • In related to mobile communication environment. Kesdogan and Pfitzmann[1,2,3] proposed solutions using temporary pseudonym identification, called TP(Temporary Pseudonym) to solve the problems concerning current locations of mobile users and exposure of their movements in the privacy aspect. After that, we proposed more improved method protecting mobile users from active attacks of network providers in [4]. But it is the case that mobile users are located in only home domain. As a more extended method. we propose new mobile terminated protocol protecting user privacy in case of moving from the home domain to the remote domain and analyze its security.

  • "The Child culture" is defined as a children's life style in which they interpret their life-situations, using their comprehension system and living out their lives based on those interpretations. Although the current Korean culture of "studying (or learning)" which is referred to as a social phenomenon restraining lively childhood of children, the ideal child culture surely exists. For this research, the total number of 1,049 articles and dissertations published around the year 2000 were analyzed from dual perspectives : value and life of both children and adults. The research literature was reviewed in respect to the following categories : 1) the dimension of how children deal with home life including food, clothing, and shelter, 2) the domain within the boundary of elementary school to understand how they spend their important time, and 3) the domain out of elementary school to understand how they spend their leisure time.
