In this paper, we propose mobile Augmented Reality(AR) for smart learning system which is advanced e-learning. AR is technology that seamlessly overlays computer graphics on the real world. AR has become widely available because of mobile AR. Mobile AR is possible to get information from real world anytime, anywhere. Nowadays, there are various areas using AR such as entertainment, marketing, location-based AR. One of the most promising areas is education. AR in education shows lifelike images to users for realism. It's a good way for improving concentration and attention. We utilize only a camera for image-based AR without other sensor.

Although x-ray had been used in Dental Clinic and taught as Roentgenology as a part of other lectures, the independent lecture was established at Seoul National University in 1953. The first independent Department was separated from the Department of Oral Surgery at Seoul National University in 1963. Nowadays, there are 6 national and 5 private dental schools in South Korea. Each dental school has a Department of Oral and Maxillofacial Radiology, which fulfills its role in student education and clinical service. What is specially noteworthy is that 8 of the 11 dental schools have changed or will change from the 2+4 year system to 4+4 year system (postgraduate course). The curriculum has also been or is being amended according to this change. Although the contents of courses for Oral and Maxillofacial Radiology are not much different among dental schools, the methods and structure of education are various. We have to do a systematic and comprehensive analysis of the present educational methods and structure of Oral and Maxillofacial Radiology and need to seek the new and more suitable ones based on competency.

E-Loaming is a modem main teaching method starting from the concept of remote education. This research is aimed for proposing cyber education library system, and designing a cyber education component that becomes a basis for e-Learning system. Cyber education library is a storage system of cyber lectures that can supply high quality data to the needed developers. Cyber education component consists of 5 categories and those are text, voice, image, animation, and flash. By using this system, the developers can save the necessary time and effort in education development. This system also helps students. The students can access various lecture data on a given subject and select the best fit for them.

The major role of school librarians in Korea has been providing reading guidance and library user education with paper resources. However, digital users have become more ubiquitous and demand more information with the images and digital materials. Therefore, school libraries need to collect more images and digital materials. At the same time, school librarians have to equip themselves with the ability to cope with this transformation. The qualified school librarians not only should have a teaching certificate but also know about techniques to transform various library materials into digital formats. Teachers and students could use these materials for their Web site homepages and Powerpoint presentations.

In this paper, we introduce a simulation tool for solar system using 3D animation tool MAYA. It accurately models solar system's astronomical features, such as each planet's orbital period, orbital speed, relative size, and texture, etc. This simulator visualize the solar system in 3D, which can be used to easily understands the system's positioning and astronomical movements. With a conventional Maya modeling process using menus and UI windows, it is difficult to assign correct physical attributes of planets. We use Python script to set up each planet's astronomical parameters. The proposed simulator is rendered as real as possible to be used for virtual reality and educational purpose.

In this study, we proposed a water rocket CULV-1 (Chosun University Launch Vehicle-1). Unlike a conventional water rocket, CULV-1 can perform the booster rocket, fairing, and payload separation like an actual launch vehicle and also the imaging data acquisition. The conceptual and critical design of the proposed CULV-1 have been performed considering the operation characteristics. The verification tests have been performed from subsystem to system level in accordance with the established test specifications and verification procedures. Through the final launch test of the flight model, we have verified the design effectiveness of the proposed separation mechanisms for water rocket applications and the mission requirements of the CULV-1 also have been complied.

Reading Pen is used mostly in educational purpose, yet its possibility is great as an input device for various IT devices. Reading Pen recognizes tiny dot patterns printed in papers, converts the patterns to corresponding codes, and plays audio contents that match the codes. Recognizing dot patterns and converting to the codes are the main function of Reading Pens, on which we focus and propose a novel algorithm. Such technology is never open to public and this paper is the first open attempt in this area. We test the algorithm and obtain 85% recognition ratio.

This research has been conducted to know the effect of advertisement according to consumer's need for cognition in the advertisement which is realized technique of the Internet of Things(IoT). The researchers distributed questionnaires and video advertisement, which is realized by using IoT technologies, to university students in the capital area after simple orientation about IoT advertisement. The result was that people who has high consumer's need for cognition showed more positive attitude to advertisement and it was statistically meaningful. As a result, the research could draw a conclusion that people have different attitude to advertisement that is realized using IoT technologies based on the consumer's need for cognition.

최근 실감형 미디어에 대한 관심이 증폭되고 있으며 제조, 교육, 의료, 국방 등에 분야에서 기존 산업과 융합하여 많은 연구가 진행되고 있으며 MPEG에서도 이러한 실감형 미디어 기술에 대한 자체적인 표준화가 진행 중에 있다. 하지만 실감형 미디어에 대한 제작기술과 디스플레이기술에 대한 이슈는 있으나 콘텐츠 보호에 대한 기술 연구는 활발하게 진행되지 않고 있다. 더구나 실감형 미디어가 최근 웹하드, 토렌트 등에서 불법 유출 되고 있어 이에 대응한 저작권기술연구가 필요하다. 본 논문은 MPEG 산하에서 표준화가 진행되는 실감형 미디어 지원 포맷인 OMAF 구조를 설명하고 이에 대한 기술적 특징을 활용하여 특징점으로 활용될 수 있는 이미지 영역에 대한 선택 방안을 제안한다.
