Mobile devices like iphone, ipad, kindle, and PDA are used as everyday tool. In the mobile environment, smart phones and other mobile units are also used as a tool for protection or infringement of personal information. Therefore, smart monitoring technology is required to protect personal information and privacy. On the other hand, with smart phones and the mobile environment, diverse application technologies are realized on hardware and software platforms. Therefore, this paper designs the network structure that forms privacy trust zone, and based on this, deals with the monitoring and monitoring prevention system with a focus on CCTV, through which this paper proposes a system that provides privacy trust zone information and its utilization which is capable of smart monitoring.

Many people are now enjoying mobile games using various smartphone platforms. However, we have to develop games separately for each smart device platforms so far. Cocos2d-x, a game development framework is released to solve this problem. As a multiplatform version of the existing Cocos2d, Cocos2d-x can make one source code run on various platforms. It is an open software that is able to be used by everyone, and when using it, mobile games can be developed easily based on C++ and OpenGL. In this paper, we implemented a PC laboratory decorating game application, named ILove501, using Cocos2d-x. The 501 is a room number of our PC lab. ILove501 includes an educational feature of solving quizzes in order to highlight positive effects of game. For implementation of a multiplatform game, ILove501 was developed in Windows and iOS environment at the same time, and we verified the results of the execution by porting on a variety of devices such as Android, iPhone, iPad and Galaxy Tab.

Mobile devices diffusion begins by the iPhone and spreads by the Android. A widely used mobile devices is Smartphone(iPhone, Android, Bada, WindowPhone7, BlackBerry, etc) and Tablet(iPad, Android). In the past, we have developed a dedicated application for device. But, Now we must develop a application by considering the characteristics of the operating system. Accordingly, many problems occurred and other developmet methods have emerged. In this paper, we learn about MobileHybridApp development tool-oriented One Source Multi Use-and compare the differences, propose a method to develop context-sensitive.

In the digital age, children can express their ideas in both physical and digital environments. Electronic textile or e-textiles with Lilypad Arduino provides children with opportunities to explore design ideas and to realize their imagination into physical artefacts. This study aims to analyze the nature of activities and perceptions among 16 children in fifth and sixth grade in a primary school in Seoul who participated in the 12-week e-textile project. To this end, two teachers who taught the class evaluated student-created artefacts from technical, critical, creative and ethical perspectives, and interviewed seven students to extract concrete experiences. The contribution of this study is that it offers a case study of how e-textile programs integrating arts and technology can be implemented in primary school settings and provides implications for future research directions.

The purpose of this paper is to review recent articles on applying smart learning for elementary students with learning disabilities. The search procedures through the Web-database system were implemented to find the proper research. Finally, a total of 10 articles met the criteria and were included in this review. Each study was analyzed according to the categories of the population, setting, research design, and intervention. The results indicated that research design implemented as case study and single subject design. Results founded strategies applying smart learning leaned too much towards using the skill-based application as learning contents. Based on analysis results, considerations for smart learning for elementary students with learning disabilities were suggested.

최근 스마트기기가 발전함에 따라 종이책이 아닌 다양한 전자책뷰어가 등장하고 있다. 애플의 아이패드(iPad), 아마존의 킨들(kindle)과 같은 태블릿, 전자책 또는 스마트폰이 대표적인 예이며 스마트기기의 사용자 증가로 전용 단말기가 아닌 스마트폰 중심의 전자책 시장도 크게 성장하고 있다. 하지만 시니어 또는 스마트기기 사용을 어려워하는 사용자들이 전자책을 사용하는데 어려움을 느끼기 때문에, 전자책은 종이책에 비해 여전히 낮은 이용률을 나타내고 있다. 본 논문에서는 얼굴 표정에 따라서 전자책 설정을 자동으로 변경해 주는 방법을 제안한다. 제안한 방법은 표정감지를 위하여 OpenCV 라이브러리를 이용하여 얼굴을 검출하고, Haar-Like 피처 기법으로 사용자의 눈 모양을 검출한다. 눈이 감겨있는 경우와 찌푸린 경우를 감지하여 이에 맞게 글자크기와 화면을 자동으로 설정해 준다.

Storytelling which is part of human nature, has changed over millions of years. The development of technology and media has shaped Storytelling into various forms and shapes, and due to the recent spread of smart devices, the influence of interactive storytelling has grown significantly. The technology which allows diverse and natural input of users, have transformed the listener to user and has allowed the user to 'experience' the story rather than 'hear' it. In line with the trend in the development of these technologies, this study seeks to design and implement an interactive tale for children on an ipad platform. Focusing on the interaction aspect, this story is designed mainly for 3-7 years olds, which contains various multimedia elements and interaction elements that use built in technology such as multi-touch technology and microphone technology to allow user input that aline with the context of story. Focusing on children's experience and empathy with the characters of the story, 'Three Little Pigs and the Wolf' contains 22 steps and was published in the itunes Store.

Generally, sound-absorbing materials in vehicles are used for giving the comfort to passengers by reducing noise while driving. Materials of which targets are light weight, high performance, eco friendliness and recycling have been developed recently. In this study, sound-absorbing materials using PET(polyethylene terephthalate) hollow fibers to achieve the light weight and the high sound absorption performance are developed, and then evaluated to meet a requirement for the automotive components. The test results show that the acoustic performances of developed products having new fiber structure are better than those of the conventional product.
