The smart devices are used more and more, these days. It make the teaching method using smart devices possible and it is considered as important method in the modern society. Though this kind of approach is prospering in foreign countries, it is not so in the domestic education system. Therefore, this paper proposes the mobile web system supporting the active interaction between the teacher and the students for the domestic education. This system can be used everywhere smart device is connected to the internet. The teacher set a question and the students answers against it through the system in real time. All questions and answers are written into the system and it can be checked again visually. It makes teachers and students trace and evaluate their interaction. And the teacher can download those result in microsoft Excel file format. We did a survey on this system to students and got positive response.

By the dissemination of the electronic blackboard systems, smart devices, and digital contents, the Korean government is recently conducting the project that replaces the classic education which utilizes paper textbooks with SMART education using various devices. Also, teachers in the field must be easily able to use SMART education infrastructure for the activation of SMART education. Especially, since the electronic blackboard is expected as a education device which will be most common for teachers, the writing software operated on the this device must supports a simple interface. And the usage of it must be simple. In this paper, we developed the writing software for the electronic blackboard which everyone can use easily. Our writing software supports the basic writing function, the human gesture recognition function which recognizes the user gesture and performs works corresponding with that gesture, and the automatic button alignment function based on the frequency of the usages.

The present study proposes an innovative approach to develop educational contents for the field trip with creative activities. In the study, the field trip with creative activities extends students' learning spaces from not only the classroom but also social circumstances. With the use of the Creative Resource Map (CRM) for students' field trip, students can approach to rich contents whenever and wherever they want. For this, it is necessary to have a variety of curriculum-related contents. For the content development, it is important to enhance mutual cooperation between school and local community as well as to create local capacity for the development of the u-learning contents with smart devices.

Various efforts are being made to live a Green life began to recognize an importance of eco-friendly living. In this paper, we have designed and implemented a mobile-based environmental keeping education service, which is offered well-defined category searching and environmental outreach related designed categories, for the purpose of supporting distribution of educational application. The implemented prototype system not only plays a function of environmental pollution report, related to simple environmental stewardship schemes, but also provides environmental monitoring service and integrated educational system supporting certified online volunteer activity. This study provides an one of famous methods to the youth for environmental monitoring education system based on mobile environments, and suggests an improvement to the environmental education for schools students.

As IT technology develops rapidly and the personal dissemination of smart devices increases, video material is especially used as a medium of information transmission among audiovisual materials. Video as an information service content has become an indispensable element, and it has been used in various ways such as unidirectional delivery through TV, interactive service through the Internet, and audiovisual library borrowing. Especially, in the Internet environment, the information provider tries to reduce the effort and cost for the processing of the provided information in view of the video service through the smart device. In addition, users want to utilize only the desired parts because of the burden on excessive network usage, time and space constraints. Therefore, it is necessary to enhance the usability of the video by automatically classifying, summarizing, and indexing similar parts of the contents. In this paper, we propose a method of automatically segmenting the shots that make up videos by analyzing the contents and characteristics of language education videos and indexing the detailed contents information of the linguistic videos by combining visual features. The accuracy of the semantic based shot segmentation is high, and it can be effectively applied to the summary service of language education videos.

The purposes of the study was to investigate BYOD (Bring Your Own Device) policy since it would be limited to distribute all of the digital devices required for the schools within the budget of the government. First, the concept and characteristics of BYOD were introduced. Then, the pros and cons of BYOD were analyzed according to the case studies of BYOD policies of the U.S. Based on the previous experiences, guidelines of domestic BYOD policies were established. Regarding the institutional aspect, technical issues, usage, damages, digital divide, information security, and resources were discussed. Additionally, conditions of technology, networks, filtering, software were also considered as essential infrastructure. In sum, as an alternative of distributing digital devices in schools, the importance of BYOD should be regarded as top priorities with systematic preparations in launching digital education. It would be expected that this study play a fundamental role in launching domestic BYOD policy by supporting specific strategies.

최근 IT기술의 발달로 디지털 미디어 기기를 가지고 수업을 하는 학교와 가정이 늘어나고 있다. 이로 인해 많은 교육용 앱이 증가하고 있다. 하지만 기존의 인터넷을 이용하는 온라인 앱은 타 서비스와 상호작용을 할 수 있지만 학습자의 집중력을 흐릴 수 있고 저학년의 학생들에게는 사용법이 복잡할 수 있다. 이러한 문제점을 보안하기 위해서 본 논문에서는 인터넷의 환경 없이 사용하기 쉽고 학습에만 집중할 수 있는 앱을 제안한다. 이 앱을 설계하기 위해 인터넷을 이용하지 않고 XML을 이용한 문제조회용 앱을 구현한다. 본 논문에 제시된 방법을 이용하면 사용자 환경에 집중을 둔 앱을 만들 수 있다.

변광 천체 중에서도 특히 수 일 만에 몇 등급 이상씩 증가하는 격변광 현상을 보이는 고에너지, 고중력 천체들의 연구는 다른 천체들의 연구는 별의 진화의 마지막 단계를 연구하는데 있어서 매우 중요하다. 고중력 변광 천체들의 연구에 있어서 선진국들에서는 지난 수 십 년간 관측기기의 눈부신 발전과 함께 고에너지 천체들에서의 다양한 복사 및 산란 과정의 규명에 많은 발전이 있어왔다. 최근 들어 지상 광학 및 적외선 망원경은 점점 대형화 하는 추세에 있지만, 소형 망원경을 이용한 변광 천체의 연구 역시 점점 활발해 지고 있다. 따라서 이러한 소형 망원경을 이용한 격변광 천체의 관측은 국내외에 우리나라가 보유한 소형 망원경으로도 충분히 관측 연구 및 교육용으로 활용이 가능하다. 한국천문연구원이 보유한 원격 관측이 가능한 미국 레몬산의 1미터 및 보현산의 1.8미터 망원경을 이용한 격변광 천체들의 최근의 관측 연구 활동을 소개하고자 한다.

The purpose of this study was to investigate the existing augmented reality (AR) contents in education and to develop digital AR contents to promote the learning outcomes in nursing skills education. AR contents has been widely used in education such as children's books, coloring, or exhibition experiences, but rarely developed in nursing education. We wanted to develop AR contents on nursing skills which required memorization of complex contents. In order to improve nursing students' memorization skills, we developed AR techniques holding and executing cameras along with game elements of time and points. In order to give the effect of placing objects in front of the user's eyes, an augmented reality camera was applied, and a total of 40 levels were created to produce the sequence of nursing techniques. This study showed that learning contents in the medical field requiring expertise could be implemented as AR contents. The content developed in this study will be used as a learning aid for nursing students.
