스마트폰과 스마트TV와 같은 다양한 콘텐츠 소비 단말들이 급속히 보급되는 최근의 IT환경에서는 콘텐츠 제작, 유통, 소비에 있어서 예전과는 다른 패러다임을 요구하게 되었다. 예를 들어 각기 다른 해상도, 연산량, 사용자환경 등의 다양한 조건들에 대한 고려가 중요한 문제로 부각되고 있다. 이를 해결하고자 단일 서비스 콘텐츠 패키지로 여러 단말들에게 적응적인 서비스를 제공하는 Scalable Application Description Language(SADL)에 기반한 스케일러블 어플리케이션 프레임워크가 제안되었다. 본 논문에서는 이러한 스케일러블 어플리케이션 프레임워크에서 적응형 서비스 콘텐츠를 쉽게 생산하고 패키징 할 수 있도록 이클립스 공개소스 플랫폼 기반의 저작도구를 제안 및 개발하였다. 개발한 저작도구는 유지 보수 및 확장성을 고려하여 모델-뷰-컨트롤러에 기반한 Graphical Editing Framework(GEF)를 이용했다. 제안하는 저작도구는 다양한 운영체제에서 작동하며, 유지보수 및 확장성이 우수하다. 또한 서비스 콘텐츠 개발을 위해 이클립스 플랫폼이 지원하는 다양한 플러그인 도구들을 그대로 활용 가능하다는 장점을 갖는다. 뿐만 아니라 본 저작도구는 기능의 추가적인 확장을 통해 홈 내 가상화 장치들을 위한 응용 프로그램 제작에도 활용할 수 있다.

Along with the transformation of the knowledge-based environment, e-learning has become a main teaching and learning method, prompting various research efforts to be conducted in this field. One major research area in e-learning involves adaptive learning systems that provide personalized learning content according to each learner's characteristics by taking into consideration a variety of learning circumstances. Active research on ontology-based adaptive learning systems has recently been conducted to provide more efficient and adaptive learning content. In this paper, we design and propose an adaptive learning system based on the concept lattice of Formal Concept Analysis (FCA) with the same objectives as those of ontology approaches. However, we are in pursuit of a system that is suitable for learning of specific domains and one that allows users to more freely and easily build their own adaptive learning systems. The proposed system automatically classifies the learning objects and concepts of an evolved domain in the structure of a concept lattice based on the relationships between the objects and concepts. In addition, the system adaptively constructs and presents the learning structure of the concept lattice according to each student's level of knowledge, learning style, learning preference and the learning state of each concept.

This study was conducted as an need analysis through close and open semi-structured surveys, in order to identify the adaptive elements of the adaptive e-learning system. The study was conducted on students majoring computer education in teacher's college. In terms of the process of the need analysis, Rossett Model was applied. For the research method, responses on the open questionnaire were analyzed. In terms of the analysis method, coding was used to extract the theme of the content, and through the constant comparison method, categorizing took place. As the element that offers adaption in the adaptive learning system, it escapes from the existing learning style, and recognized the importance of providing adaptability for different elements such as the learner's level, learning objectives, and learning contents. Especially, An instructional model was identified as an important element that helps reach rationality as well as efficiently conduct the learning objectives.

Recently, with the digitalization of a broadcasting system and the development of a communication technology, the existing trend of consuming media contents throughout the fixed-displayer and the dedicated channel is being changed. The existing user only could consume media contents under limited time and places because of the fixed-displayer and the dedicated channel. However, with advent of the IP-based terminals and HTTP adaptive streaming which transfer the media sequence according to the user's transmission condition, users become possible to enjoy the media content anytime anywhere. As the result of the alteration of the broadcasting surrounding, users can enjoy the media content while changing his terminals according to their preferences and circumstances. However, in case that users try to consume consecutively the content from last view-point ended in the previous terminal under current HTTP adaptive streaming environment, a user has to remember the last view-point, and then has to apply the view-point to the changed terminal. Thus, for solving this problem, this paper defines "User Profile" for describing the metadata for the chained content consume environment between the terminals. Also, for proving the proposed method, this paper try to demonstrate the proposed method throughout the realization of the system based on Smooth Streaming from Microsoft.

This study aimed to verify the mediating effects of empowerment and social support in the process of parent-child relationship affecting the college adjustment. In this descriptive research, 219 university students were recruited as participants. Data collection was carried out from May to June 2019 via online survey. The results showed that parent-child relationship had significant direct effects on empowerment, social support, and college adjustment. Moreover, parent-child relationship had significant indirect effects on students' college adjustment via empowerment and social support. The indirect effect of empowerment was significantly higher than the indirect effect of social support with respect to the influence of parent-child relationship on college adjustment. It is necessary to improve parent-child relations and emotional intimacy through social support to promote the college adjustment of students. In addition, it is important to apply a program that can enhance empowerment, which is a powerful factor in college adjustment.

This study examined the acculturation strategies of immigrant women and the relationship in adolescents' career development. The data were from 2016 Multicultural Adolescents Panel Study, 1,248 cases. The highest rate was the assimilation followed by integration, separation and marginalization among immigrant women' acculturation strategies. The parenting efficacy, behaviors for career development and parents' support were related with acculturation strategies. The adolescents' career attitudes and perceived career barriers were also related with the acculturation strategies of immigrant mothers. As compared other strategies, assimilation strategy had positive relationships with parenting efficacy, behaviors for career development, parents' support, adolescents' career attitudes and perceived career barriers. This study provided some implications for immigrant families with adolescents.

The objective of this study is to present a prototype of organic content, using 3 Screen as the basic concept, and to examine the possible applications of such models. Organic content is something with the characteristics of an organism, which adapts to each unit while maintaining connectivity without losing identity, according to the situation of the user and the characteristics of each unit, opposed to contents that exist without connectivity among units. To this end, I produced a prototype called "Fishing Phone," which crosses over TV, 모바일 and PC. In the Fishing Phone, the fish adapts to each unit as it interacts differently with users while maintaining its own identity. It is an organic content that travels freely through the 3Screen. Fishing Phone was created by using technology and products widely used and serviced today, such as WiFi, java networking, flash player 7, omnia2, and space censors. It demonstrates that organic content can transcend the limitations of space in existing contents, generating new value, realizing complex interaction, and ultimately providing advanced applications for marketing.
