The digital textbook project which embarked by the Ministry of Education, Science and Technology has focused on experiments and practices from the school designated by the government. However the previous research about digital textbook provides static interaction models and teaching-learning models analogous to web-based learning based desktop PC even the framework of the digital textbook is based of Tablet PC. This paper provides learning and teaching models for next generation digital textbook which based digital inking techinques for sketcth interface and AR(augmented reality) interactions between teacher and learner. The proposed method of this paper is applied to educational contents and we found positive effect which is supported by statistical experiments. The results of this study in the future and the future development of digital textbooks in effect will be an effective development plan.

최근 디지털 사이니지 분야는 광고분야의 한정적 매체 특성을 벗어나 첨단 기술과 서비스 콘텐츠를 결합하여 다양한 분야에서 새로운 형태의 매체로 변화하고 있다. 특히, 광고 업계의 침체와 기존 단순 영상 송출의 한계를 증강현실, 동작인식, 다양한 매체간 목적성 연동, 위치기반 맞춤형 서비스 등을 제공하며 융합적, 결합적 서비스 매체로 진화하고 있다. 2000년대 초 디지털 사이니지의 국내 보급은 국외를 포함해서 보급이 매우 빨랐다. 디지털 사이니지는 광고 목적으로 시작됐지만, 외형적 성장 속도에 비해 매체를 통해 제공되는 콘텐츠, 서비스, 운용 기술 및 S/W 개발 등의 질적 성장은 상대적으로 소극적이었다. 그러나 최근 아시아를 중심으로 한류 열풍이 확산되면서 K-POP, 화장품, 의류, 바이오 등 산업을 중심으로 디지털 사이니지의 수요가 증가하는 추세이며, IT와 융복합되면서 교육, 정보 제공, 예술분야에 적극 활용됨에 따라 국내 디지털 사이니지 산업이 새로운 전기를 맞고 있다. 특히, 위치 기반 서비스는 2000년 후반 차량용 네비게이션 시장을 시작으로 현재 스마트폰에 기본으로 장착되면서 이제는 서비스 전분야에 직/간접적으로 활용되는 다양한 기술이 개발되고 있는 실정이다. 이와 같이 디지털 사이니지는 첨단 기술과 결합하여 다양한 형태의 지능적 처리 능력을 이용함으로써 현재 광범위하게 사용되는 위치 기반 기술과 서비스를 결합한 새로운 매체 인프라로 생활 공간에서 급속히 확산되고 있다. 본고에서는 현재 뜨거운 화두가 되고 있는 디지털 사이니지와 위치 기반 기술의 기술 및 시장 현황을 살펴보고, 기술 및 서비스 융복합에 따른 앞으로의 디지털 사이니지 분야와 결합된 위치 기반 서비스의 미래를 전망해 본다.

The development of content for language education using AR/VR technology is a necessary task to be pursued in line with commercialization of 5G. Research on service platform for systematic management and service is currently being carried out by global companies competitively, The unique language education service model for unique areas of culture has the right to pursue R & D jointly with Korea and China. In this study, we applied the developed "Korean language education service platform for Chinese people based on e-learning" to improve the acceptance of AR/VR contents and applied AR/VR technology to video-based language education contents. And to present a new paradigm of language education. Contents development is to develop AR-based vocabulary learning services, develop experiential learning contents for VR-based step-by-step situations, and gradually develop contents to enable beginner / intermediate / advanced language education services. The service platform enables management of learning management and learning contents, and complies with metadata attributes to complete a platform capable of accommodating large capacity AR/VR contents. In the future, systematic research will be carried out in order to develop as a portal for educational services through development of various contents using mixed reality technology.

Advancements in digital technology have caused significant changes to the tradition of creative educational activities. Such an with digital technology is prone to an error where digital technology itself becomes the goal, ignoring educational efficacy grounded on improved user experience and immersion. Previously, picture book-making activities for children allow them to actively participate in the process of book-making, and is often employed to instill reading habits as well as nurture linguistic abilities. Aside from such picture book-making activities, diverse efforts are being made for innovation in educational pedagogy through digital technology. However, as the goal of children's picture book-making activities is realizing creative education through expressions in language and pictures, digital technology should be considered in the viewpoint of fusion, not as a simple replacement to the traditional tools employed in children's picture book-making activities. This study examines previous researches related to children's picture book-making activities to propose contents and methodology allowing effective immersion by fusing digital technology based on a physical environment, from the viewpoint of fusion and integration. Expect this study will become a fundamental data in visualizing a practical integration of digital technology in future creative education.

본 논문에서는 스마트폰 환경의 혼합현실 기반 인터페이스를 사용한 영어단어 학습 게임 시스템을 제안한다. 제안한 시스템은 영어단어 학습 콘텐츠를 저작할 수 있는 저작도구와, 게임을 진행할 수 있게 해주는 스마트폰 인터페이스, 저작된 학습 콘텐츠를 실행하는 카드 매칭 게임 어플리케이션으로 구성되어있다. 이 시스템은 텍스트, 이미지, 비디오, 3D애니메이션 형식의 단어 카드를 제공하여 단순 이미지 형식을 사용한 방법보다 좀 더 구체적으로 단어를 묘사할 수 있다. 그리고 부모가 원활히 게임을 진행할 수 있도록 혼합현실 기반 인터페이스를 제공한다. 혼합현실 기반 인터페이스는 개인화된 정보를 부모에게 제공하여 부모가 사전 지식 없이 영어 단어 교육을 할 수 있도록 도움을 준다. 본 논문에서는 보급이 저조한 PDA와 UMPC대신, 최근 보급이 확산되고 있는 스마트폰에 혼합현실을 구현하여 인터페이스의 접근성을 높이고자 하였다.

Recently, software education has been emphasized as a key element of the fourth industrial revolution. Many universities are strengthening the software education for all students according to the needs of the times. The use of online content is an effective way to introduce SW education for all students. However, the provision of uniform online contents has limitations in that it does not consider individual characteristics(major, sw interest, comprehension, interests, etc.) of students. In this study, we propose a recommendation method that utilizes the directional similarity between contents in the boolean view history data environment. We propose a new item-based recommendation formula that uses the confidence value of association rule analysis as the similarity level and apply it to the data of domestic paid contents site. Experimental results show that the recommendation accuracy is improved than when using the traditional collaborative recommendation using cosine or jaccard for similarity measurements.

The digital culture area is a field of artificial intelligence education and partially overlaps with information ethics, and this study proposed an elementary school-centered digital culture curriculum, a detailed area of artificial intelligence education. First, as a leading overseas case in the field of digital culture, we analyzed the secure online interaction, which is the core content of the K12CS framework in the United States and the UK's computing curriculum. We presented by categorizing it into four digital areas: content, communication method, copyright, and job exploration in accordance with the domestic educational environment and field conditions. In addition, educational goals were stated according to the level of kindergarten and elementary school, and the validity of a group of field teachers majoring in in information and artificial intelligence was investigated to confirm the validity. As a result of the analysis, it was found that all the contents set were suitable except for some of the detailed goals of the first grade elementary school stages. Accordingly, a digital culture curriculum for artificial intelligence education was presented by revising and supplementing the detailed goals of the first graders.

Logic design using multiplexer has been used as a useful method for design convenience and flexibility in structural digital system design. In this paper, we analyze the effect of don't care conditions on logic optimization in a multiplexer-based logic design, which was not discussed enough in the previous studies in multiplexer based logic design, and describe the use of don't care conditions for designing of a single multiplexer and multiple multiplexer-based logic design. Especially, the design method when the number of data input is not 2m (as the number of selection lines is m) is considered. We also describe how to apply the proposed technique to the digital logic design education in conjunction with microprocessor design using Arduino which is widely used in creative engineering education recently.
