In this paper, we developed a new MSRDS(Microsoft Robotics Developer Studio) simulator for a quadruped pet robot with synchronization of virtual and real robots. By using this simulator, it is possible to reduce time and cost for gait and motion design and it will help for commercialization of service pet robots. In the research point of view, the simulator can be used to examine the model differences between the virtual and the real robots. Since this simulator implements the coordinated control of the virtual and real robots, it can be used as an internet game using two remote pet robots.

The flight simulation the fact that imitates the real situation of flight for the training or boarding experience which manages a same flight equipment with the aircraft in goal. The flight simulation of existing attached importance in the research and development which is limited in the control which is visible and physical relate with the management of the airplane directly. So, the flight simulation applied in various game or simulator etc. But, there were not researches which are actual applies in flight simulation with considers the physiological phenomenon of pilot. Therefore this paper tries the flight simulation which assumes the physiological phenomenon as the blackout and a redout of pilot. In conclusion, predicts a future.

The various information services can be delivered by smartphone through advanced high-speed mobile communication. A smartphone is a mobile device that offers more powerful computing capacity than feature phone. Therefore this device can provide such as web surfing, editing documents, playing video, and playing games. A lot of personal information stored on smartphone. Because it has High usability. Personal information Leaks if the smart phone is lost or stolen may become a big problem. In this paper we have analyzed existing method for providing secure storage and user authentication on mobile platform and derived security requirement. Therefore we propose the following scheme that satisfy security requirement. Proposed scheme providing secure storage with preventing authentication bypass, and availability from damaged data to access secure area.

Recently smartphone market is rapidly growing and application market has also grown significantly. Mobile applications have been provided in various forms, such as education, game, SNS, weather and news. And It is distributed through a variety of distribution channels. Malicious applications deployed with malicious objectives are growing as well as applications that can be useful in everyday life well. In this study, Events from a malicious application that is provided by the normal application deployment and Android MalGenome Project through the open market were extracted and analyzed. And using the results, We create a model to determine whether the application is malicious. Finally, model was evaluated using a variety of statistical method.

This paper proposes a method for extraction of the gaze point on display using EOG(Electrooculography) signal. Based on the linear property of EOG signal, the proposed method corrects scaling difference, rotation difference and origin difference between coordinate of using EOG signal and coordinate on display, without adjustment using the head movement. The performance of the proposed method was evaluated by measuring the difference between extracted gaze point and displayed circle point on the monitor with 1680*1050 resolution. Experimental results show that the average distance errors at the gaze points are 3%(56pixel) on x-axis, 4%(47pixel) on y-axis, respectively. This method can be used to human computer interface of pointing device for general paralysis patients or HCI for VR game application.

Educational robot was introduced as an effective educational tool is to foster scientific creativity and learn the basic principles of science are applied to change the configuration of the educational after-school learning kits for science education. SMEs as a tool to foster scientific creativity center and a variety of educational robot technology and the wide range of games for students and robotic technology development, existing e-Learning by downloading mp3 music or learning content for the robot, such as the provision of specialized content Although the technology is still being developed to take advantage of the professional community formation is insufficient side. Currently, one-point linkage drag Smart Touch control dynamic motor development does not need this motor development is possible for users to easily.

In recently, various types of applications have been developed according the smart phone has become popular. There are many kinds of multimedia, game, information, education, etc according to each user. Most of the linguistic contents in mobile based are concentrated on learning foreign languages like English, Japanese, Chinese compared that the development of contents for Korean education is imperfect. In this paper, so, we implement the linguistic contents for elementary Koran education of foreigners based on android OS to use them by smart phone.

For the past few decades, residential improvement projects have been mainly carried out after demolition of the original dwelling place. So far, interests and opinions of the existing residents have largely been ignored during the projects. However, citizen participation in local redevelopment has recently been regarded as essential part as progress in democracy and diversified public interests have offered more importance to citizen participation in the implementation of public policies. While the importance of resident participation has been increasingly emphasized in principle, there still has been more to do in its application in reality. We should develop the experience of collecting community opinion to make them reflected in public policy, if we are to achieve the resident and citizen-centered society. The purpose of this study is to develop an image map tool that can be applied to "Maul-Mandulgi" projects as a visualized method to facilitate the exchange of opinions and work toward agreements. The tool is supposed to assist the public discussion by visualizing the policies and reducing the possibility of misunderstanding, so that residents can properly respond to them. In addition, this study will verify the effectiveness of the tool in the application to local community workshops.

현재, 전세계의 전력산업은 수직통합적 독점산업에서 부문간 경쟁산업으로 변화하고 민영화를 통한 시상경쟁원리가 도입되고 있다. 이러한 전세계적 전력산업 구조개편에 발맞추고, 전력산업에서의 효율을 제고하기 위하여 우리나라도 전력산업에 시장경쟁 체제를 도입하고 발전산업에 민영화론 추진하고 있다. 2001년 4인, 전력을 거래하기 위한 한국전력거래소가 발족되었으며 6개의 발전자회사의 설립을 통하여 발전부문의 경쟁체제가 도입되었으며, 2003년부터 본격적인 도매경쟁 시장이 도입될 전망이다. 이러한 새로운 시장 환경아래에서 전력거래가 원활하게 이루어지고, 시장이 안정화되기 위해서는 정부, 전력거래소, 발전사업자 등과 같은 시장참여자들이 전력시장을 분석할 수 있는 방법론 및 모델을 확보하고 있어야 한다. 따라서, 본 논문에서는 이러한 전력시장을 분석하기 위한 방법론으로 게임이론을 적용하여 각 발전사업자의 보수전략(Maintenance strategy)을 분석하고자 한다. 이론 통해 각 발전사업자는 보수전략을 수립하는데 이용할 수 있고, 시장규제자의 측면에서는 전력시장이 효율적으로 가동되고 있는지 여부를 판단할 수 있는 유력한 도구로도 활용될 수 있을 것으로 예상된다.

In this paper, to solve the imbalance between the skill factors demanded by the industry and the curriculum of the universities, demand-oriented educational contents are developed in the computer-software field. In the field, five tracks are selected: Software Development, System Integration, Embedded System Software, Multimedia and Game Software, and Business Information Technology. In each track, a curriculum with four demand-oriented courses is developed to reflect the demands of the IT industry. Detailed syllabuses and course materials are developed as well. Applying these artifacts, lectures have been performed at universities since 2004.
