DRM은 저작권법에 의하여 보호되는 권리에 대하여 정단한 권리나 자격 없이 침해하는 행위를 방지하기 위하여 사용되는 기술적 보호조치이며, 디지털 환경에서 저작권에 대한 새로운 해석을 유도하고, 이를 지속적으로 유효하게 하기 위한 적극적인 수단이다. 본 논문에서는 DRM의 기술적인 요소에 대하여 기술하고, 디지털 컨텐츠의 합법적인 이용을 보호하는 DRM의 확산을 촉진하기 위한 기술 표준화에 대하여 논의한다. DRM의 확산을 이루어내기 위하여서는 무엇보다 DRM의 표준화에 있어서 개방형 기술을 채택하여 제품간의 상호호환성을 높이고 시장에서의 경쟁을 촉진하여야 한다. 또한 디지털 환경의 특수성을 이해하고, 이를 반영할 수 있는 법제도적인 뒷받침이 필요하다. 한편 국내 DRM 산업의 활성화를 위하여 솔루션 개발업체, 저작권자 및 관련단체, 컨텐츠사업자, 서비스 제공자 그리고 정책 담당기관의 광범위한 협조를 통하여 국내 기술표준안을 마련하고, 성공적인 사업모델에 기초하여 국제표준안을 제안하여 세계시장으로 진출할 수 있는 발판을 만들어 가야 할 것이다.

To solve the problem of copyright violation of digital contents, it has been developing and using DRM (Digital Right Management). However, it is not only insufficient situation to satisfy all demand of market yet but also the technology demanded by various market circumstance is changing. This manuscript has shortly introduced the protection technology for digital contents and looked over the direction for development and faced subjects in DRM industry. First, it introduced fingerprinting technology which is capable of tracing illegal duplication by embedding the user's information among the contents as the supplement of DRM technology. Also, we looked over the protection of broadcast contents as an example about the adaption of existing DRM system in the situation which has been changing to digital convergence circumstance. Finally, we shortly looked over standardization of the protection technology and discussed the eventual direction of coping with the situation of industry such as the problem of interoperability between the standards.

본 연구의 목적은 고등학생을 대상으로 대기와 물의 순환 개념에 대해 과제 상황(과학적 상황과 일상적 상황)에 따른 지식의 출처와 응답에 상황 의존성이 나타나는지 알아보는 것이다. 또한 이러한 상황 의존성과 학습자의 인지 양식과의 관계를 밝히는 것이다. 이를 위해 고등학생 115명을 대상으로 본 연구에서 개발된 과제 상황에 따른 지구과학적 문제 해결 검사지와 인지 양식 검사지(GEFT)가 사용되었다. 지구과학적 문제해결 검사 문항은 동일한 개념에 대해 과학적 상황 10문항, 일상적 상황 10문항으로 총 10쌍의 문항으로 구성되어 있으며 모든 검사 문항은 지식의 출처를 선택하는 하위문항을 포함하고 있다. 본 연구의 결과는 다음과 같다. 첫째, 과제 상황에 따른 학생들의 지식의 출처는 상황에 따라 달라짐을 알 수 있었다. 즉, 과학적 상황과 관련된 문항에서는 ‘학교에서 과학수업시간’을 그리고 일상적 상황과 관련된 문항에서는 ‘일상생활에서의 경험이 주된 지식의 출처였다. 둘째, 과제 상황에 따른 응답의 일관성을 알아보기 위해 각 상황에서 일치하는 응답 수를 일치 점수로 나타내어 비교한 결과, 불일치 점수가 일치 점수에 비해 유의미하게 높았다(p〈.01). 따라서 과제 상황에 따른 응답은 일관성 없으며 상황 의존적임을 알 수 있었다. 셋째, 장의존형 학생은 장독립형 학생에 비해 일치 점수가 낮음을 보였는데 이는 인지 양식에 따라 상황의존성에 차이가 있음을 시사한다.

In order to enhance the effectiveness of students' learning behavior through teaching, it is necessary to investigate the differences between competent and less competent teachers' teaching practices. Furthermore, it is also important to examine various w

The purpose of this study was to determine the most effective method of forming cooperative small groups for middle school English classes using ICT. To achieve this goal, the two experimental classes composed of 73 middle school 2nd graders were taught in a task-based teaching-learning model using ICT for 12 weeks. Throughout the 12-week period, two types of grouping models were applied to the students: Experimental class A consisted of differentiated heterogeneous group based on the regular English examination marks, and experimental class B was made up of a differentiated heterogeneous group based on the ICT skill standard for student (ISSS). The study discovered the small group based on the ISSS showed significantly different statistical results in the cognitive, affective and information-using skills. The ISSS could be used as an additional criterion in forming small groups for middle school English classes. In fact, the study shows that it creates better results than the traditional grouping based on learners' English grades if the lessons are given in using ICT.

The purpose of this study is to investigate the effects of using and authoring web-based vocabulary learning tasks on Korean EFL learners' vocabulary acquisition. The subjects of the study were seventy-seven EFL college students in Korea. They were divided into three groups: a traditional control group, and two experimental groups using and authoring the web-based vocabulary tasks, respectively. The major results of the study were as follows: first, the two experimental groups performed significantly better on the vocabulary recognition and use posttest than the control group did. This result indicates that both the use of the web-based tasks and the participation of students in authoring the web-based tasks are more effective in vocabulary acquisition than the use of traditional vocabulary learning methods. Second, both the experimental groups performed significantly better on the delayed posttest than the control group did. This result provides evidence that using and authoring web-based vocabulary tasks are effective in helping students retain newly acquired words in the long-term memory. Third, the learners' responses of the two experimental groups prove to be positive with respect to the use of the web-based task authoring tools in vocabulary learning. Based on these results, some pedagogical suggestions should be made on the effective use of the web-based task authoring tools in Korean English classroom settings.

The aim of this artic1e is to introduce the contour of the history of the EATWOT (Ecumenical Association ofThird World Theologians) from 1976 to 1992 and to point out its significance and tasks from the mission perspective. The international conferences of the EATWOT deal with three issues: analysis of reality of the third world, missionary tasks of church, and reformulation of the third world theology. Characteristics of the third world are poverty and oppression. However these issues cannot be reduced to socio-economic matters. The rea1ity of the third world cannot be understood fully until third world theologians are able to account for the cultural is sues Missionary tasks of church include liberating mini stry, social responsibility for local community, suggestion for an a1ternative value system to capitalism, and recovery of Christian spirituality overcoming dichotomy between faith and life, prayer and action, commitment and every day life. Methodology of third world theology is the commitment to liberation and contemplation. Its authenticity depends upon to what extent it relates to rea1ity. The significance of the EATWOT from the mission perspective is, first of all, in that its theological center shifted from history to creation. Secondly, its understanding of the third world was enlarged by adding the aboriginal, the Indians of Latin America, and even gays and lesbians to the people of Asia, Africa and Latin America. Thirdly, it changed its attitude toward women and ferninist theology through which doing theology itself can be changed. Fourthly, not only socioeconornic analysis but also religio-cultural analysis are necessary for understanding the reality. Fifthly, as time passed, it reahzed the significance of spirituality. Important resources of spirituality could come from other religions, women, and the aboriginal. Sixthly, in relation to methodology of doing theology, the committment to struggle for ju stice and liberation was complemented by contemplation. Lastly, the subject of doing theology is not academic theologians but the faith community. One of important tasks of the EATWOT is how to harmonize the socio-econornic approach and religio-cultural one. In principle, every Christian is a theologian. However, without training the faith community and transforrning it into a hermeneutic community, this principle becomes meaningless. Even though the EATWOT declared “ the irruption of the third world", this irruption failed to bear fruits in the world. The changes in the times such as the collapse of the Eastern Socialist countries, the end of the ‘Cold War’ , the neoliberal global capitalism, and globalization resulted in ‘the world without a1ternatives' or ‘the end of history ’ . One of urgent tasks of third world theology is to suggest the alternative world through integrating personal, social, national, and global issues, and being solidarity with various kinds of NGOs at the local, national, regional and globallevel for the sake of globallife community.

The article aims to analyze the mission없y activities of Korean churches for Korean diaspora in China and to suggest some missiological tasks for them. The article consists of three parts. The first p따t deals with the Korean diasporas in China for whom Korean churches have done missionary activities since 1980s. Such as a historical formation of the diaspora community and a reflection of the missionary enterprises of the Korean churches and their missiological tasks for them are included. The second p따t discusses the Korean diasporas in China who have immigrated into Korea as foreign migrant workers. Also the article criticizes the missionary activities of the Korean churches for them and proposes some missiological tasks. The last part emphasizes on realization of the Konvivenz mission which results from the missiological reflections on the missionary activities of the churches. The Konvivenz mission is accomplished through mutual efforts of both the Korean churches and the KoreanChinese.

목적 : 본 연구는 뻗기 과제를 수행하는 동안 팔과 체간의 움직임에 있어서의 차이를 알아보고자 실시하였다. 정상 성인을 대상으로 책상 위에서의 팔뻗기 과제 수행시 거리에 따른 팔의 움직임에 대한 체간의 움직임을 알아보기 위하여 대상자의 팔의 길이에 비례하여 다양한 거리에서의 팔뻗기 과제를 실시하였다. 연구방법 : 연구대상자는 상지에 선천적인 기형, 심각한 외과적 혹은 신경학적 질환이나 지난 1년 동안 상지의 외상이나 통증을 경험했던 사람은 제외한, 우세 손이 오른손인 건강한 성인 20명을 대상으로 실시하였다. 상지움직임의 변화는 실시간 삼차원 동작분석 장치인 CMS-HS를 사용하였다. 팔길이에 대한 50%, 70%, 90%, 110%, 130% 거리의 작업수행시 체간의 움직임이 측정되었고, 단일 표식자에서 얻어진 속도와 움직인 거리 그리고 체간과 상지의 최대속도시간을 나누어 처리하였다. 결과 : 거리가 증가하는 동안 체간의 움직임은 팔의 길이의 90%의 거리에서부터 체간의 움직임이 유의하게 증가됨을 보였다(p.<05). 팔의 움직임에 대한 체간의 회전은 팔길이의 70% 거리에서부터 유의한 회전을 나타내기 시작했다(p.<05). 팔과 체간의 최대속도 도달시간은 팔길이의 70%, 90% 110%의 거리에서는 팔의 최대속도 도달시간이 먼저 나타났고, 팔길이의 130%의 거리에서는 체간의 최대속도 도달시간이 팔보다 먼저 나타남을 보였다. 결론 : 본 연구의 결과 거리에 따라 팔의 움직임에 대한 체간의 회전과 굴곡이 유의하게 일어나는 거리를 알 수 있었고, 거리에 따른 체간의 운동속도에 있어서의 움직임 패턴을 예측할 수 있었다. 따라서 상지 손상이 있는 환자들의 책상 위에서의 작업 수행이나 작업치료시 작업이 일어나는 거리에 따라 체간의 올바른 움직임을 위한 더 많은 연구가 필요할 것이다.

The soaring increase in the number of Internet users combined with the constant computerization of business process has created new opportunities for computer criminals and terrorist.

The purpose of this study was to propose a task-related circuits program for stroke patients and to test the difference in functional improvements between patients undergoing conventional physical therapy and those participating in a task-related circuits exercise program. The subjects were 10 stroke in-patients of the Korea National Rehabilitation Center in Seoul. We measured the following variables: Motor Assessment Scale (MAS), Berg Balance Scale (BBS), Tone Assessment Scale (TAS), speed of gait, rate of step, physiological costs index, age, weight, height, site of lesion, onset day and whether the subject participated in an exercise program. Collected data were statistically analyzed by SPSS 10.0/PC using descriptive statistics, Mann-Whitney U test, Wilcoxon rank sum test and Spearman's correlation. The results of the experiment were as follows: (1) In the pre-test and post-test for function, there was not a statistical significance between the group partaking in a task-related circuits program and the group of conventional physical therapy (p>.05). (2) In the MAS, BBS and speed of gait test, the group undergoing conventional physical therapy showed a statistical significance (p<.05). (3) In the MAS, BBS, speed of gait, PCI, TAS (passive, associated reaction, TAS total score), the group of task-related circuits program showed a statistical significance (p<.05). As a result, the group participating in a task-related circuits program had a more functional improvement than the group participating in conventional physical therapy. Therefore, an intervention recommended for a stroke patient would be a task-related circuits program consisting of a longer session of each task for a more improved functional recovery.
