오늘날 DRM 벤더별 독자적인 기술규격 사용으로 디지털 콘텐츠 및 디지털 기기의 상호호환성이 보장되고 있지 않으며, 디지털 콘텐츠의 권리를 보호할 수 있지만 사용자는 많은 제한과 불편을 감수해야 한다. InterTrust사가 제안한 Superdistribution은 콘텐츠 획득에 상관없이 오직 라이선스와 사용자 인증에 의해 콘텐츠 사용이 가능한 콘텐츠 분배 기술이다. 그러나 원래 콘텐츠가 사용자 소유의 디바이스로부터 다른 디바이스로 이동되어야 할 때 DRM 서버로부터 재 인증과 함께 추가적인 라이선스를 필요로 한다. 이 논문에서는 재 인증과 라이선스 재발급 절차의 불편함을 줄이고 오프라인 상에서 지속적인 콘텐츠 권리의 보호를 위해, 홈 디바이스 간에 도메인을 생성하고 사용자가 도메인 안에서 자유로운 콘텐츠 이동 가능한 DRM 시스템을 제안한다.

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.

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.

이동 컴퓨팅 환경이란 사용자가 어떤 장소로 이동하더라도 동일한 환경에서 네트워크 서비스를 지속적으로 끊임없이 제공받을 수 있는 환경을 말하며, Mobile IP는 이러한 환경이 가지는 특성들을 고려한 네트워크 표준 프로토콜이다. 하지만 이 프로토콜도 이동 노드의 빈번한 핸드오프 시 위치 등록 절차에서 반드시 흠 에이전트 (Home Agent, HA)를 접근해야 하므로 네트워크 자원과 서비스 지연을 초래하는 단점을 가진다. 따라서 본 논문에서는 지역적 외부 에이전트 (Foreign Agent, FA) 기법을 도입하여 방문 도메인에서의 등록을 지역화 하여 이동 노드의 빈번한 핸드오프 시 위치 등록 절차에 대한 지연 부하를 최소화 하는 방안을 제안한다. 또한 부하 분산 요소를 부가하여, 모든 FA가 상황에 따라 동적으로 루트 권한 FA가 될 수 있는 기법을 도입하여 중앙으로만 집중되는 위치 등록 메시지를 지역적 FA에 분산하여 네트워크 자원 낭비를 줄이고 빠른 위치 등록 응답 시간을 얻을 수 있으며 기존 Mobile IP에서의 패킷 지연 및 손실 그리고 재전송을 예방하고자 한다.

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.

"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.
