모바일 기기의 사용량 증가와 성능의 증가로 인해 컴퓨팅 파워가 필요한 많은 분야에서 모바일 기기를 활용 할 수 있게 되었고, 의료영상 분야에서도 활용도가 높아졌다. 특히 전문가가 아닌 일반인들의 건강정보와 인체의 구조에 대한 관심이 증가함에 따라 휴대 가능한 모바일 기기에서 의료영상을 가시화는 것은 중요한 연구주제가 되었다. 하지만, 모바일 기기는 하드웨어의 한계가 있기 때문에 비교적 데이터의 용량이 큰 의료영상 가시화에 많은 제약이 따른다. 본 논문에서는 유니티3D를 활용하여 볼륨렌더링 어플리케이션을 개발하고, 여기에 사실적인 컬러정보를 포함한 Visible Korean 데이터를 적용하여 일반인에 적합한 인체정보를 제공하는 모바일 기기용 인체영상 학습 어플리케이션을 제안한다. 제안한 어플리케이션을 사용하면 매우 사실적인 인체영상을 이용하여 일반인들이 쉽게 인체 구조를 학습할 수 있다.

Recently many research reports on effective use of mobile devices for museums to provide information on displayed artifacts providing individualized learning space, collaborative learning, and discovery learning, Such devices have many possibilities to support learning as a participatory media and social network. Mobile devices are used, however, limited for its usability and lack in providing expected learning experiences. It offers one-way interaction and they are often limited in providing customized services for different patrons to experience learning and entertainment. In this research, we have adopted user centered design approach to identify the needs and possible usage of PDA system in the museum. Research methods include contextual observation and inquiry with symbolic interactionism for qualitative research and its epistemology. We have developed conceptual model with scenario and storyboard method, and developed vertical prototype with Flash.

As propagation of mobile smart devices is widespread, it is an observable trend that the cases of utilizing them are increasing in the school programs, and it is also anticipated that they will be very important part of the educational equipment in near future. For this reason the department of education and science technology has announced a medium and long term project on the education with smart device, which is undergoing the preparation stage, and the various academic and industrial institutes have actively produced the related research results and the application prototypes. In this paper we propose a framework on design and implementation of a visual context recognition system for educational purpose usable in the school program by utilizing a module for recognition of the texts embedded in the image captured by video camera from mobile smart device. The system proposed in this paper is consisted of the four modules, such as, image acquisition, image processing, information extraction, and knowledge representation, which are explained in details with the practical examples.

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.

This study investigated the structural relationships among factors on intention to use mobile learning and suggests practical strategies to enhance learners' behavior intention in secondary school. In this study, we hypothesized that mobile computing self-efficacy, personal innovativeness, and social influence had positive effects on perceived usefulness and perceived ease of use, which ultimately had positive effects on intention to use mobile learning. In order to examine structural relationship among variables, we surveyed 289 high school students in spring semester of 2014. After collecting data, we examined causal relationship among variables using Structural Equation Modeling. The results of this study are as follows: First, mobile computing self-efficacy and personal innovativeness significantly affected perceived ease of use. Second, mobile computing self-efficacy, social influence, and perceived ease of use significantly affected perceived usefulness. Lastly, perceived usefulness and perceived ease of use significantly affected intention to use mobile learning of high school students.

Mobile games have emerged as the most innovative entertainment technology, adding new revenue streams, taking advantage of the potential of wireless applications and service offerings. Mobile games, like any other types of computer game, offer a unique value for users in providing an exciting digital experience in virtual worlds. Players can become empowered through the development of new characters and strategies within games to achieve rewarding successes against the computers and other players. In this paper, we attempt to examine the motives of adolescents for playing mobile games. Based on data collected from survey, we have identified Escape, Arousal and Fantasy, Challenge and Competition, Diversion and Relaxation, Social interaction as the key motivators for playing mobile games. We also investigated the extent to which use and gratifications are predicted by demographic factors as well as by gaming experience. Statistical results confirm that most of the demographic factors played critical roles in determining the level of motivations for playing games. The results from this research might give mobile game industry some useful guidelines for developing mobile edu-game and market expansion strategy.
