The market of the smartphone game has been changed rapidly which can be seen in the online PC game, ‘SNG’ and became popular among the game lovers. In the same way, ‘Kakaotalk’ has also been appeared suddenly. Therefore, in this research work, we figured out the exploratory factors that affect the intention of use of smartphone users and these effects can help future works on games to those who are doing research on it. In our research method, we reviewed the preceding related researches about the intension of use of smartphone users. Based on these researches, we have extracted factors for suggesting research model and then verified the hypothesis with actual analysis to find out which factors are affecting the intention of use of smartphone game users. The factor and reliability analysis have done in order to examine the validity and reliability of the questionnaires used in this work. As the result, popular genre, character, sequence of hit etc. are affected positively on intention of use of smartphone game users but there are no meaningful effects of game developers. Due to such research, it can be helped to the related game developing academic and industries researchers on intention of use of smartphone games users.

In everyday network changing field, permanent service is being an issue. Network disconnection phenomenon is directed to financial damage to service providers. Some companies guarantee on network maintenance, but there is a permitted limit according to their company regulations. If customers overuse the limitation, extra pay will be placed. Moreover, network disconnection affects critical in some fields with using network. Permanent service becomes indispensable in stock, finance, online game, and other fields. Additionally, it should be possible to pre-detect and block abnormal traffic area, improve network infrastructure secureness and optimization, and reduce damage recovery cost. MCS(Multi Connection System) can provide permanent service even if a connection is cut because it provides multi-connection. It can also isolate the attacker when it detects DDoS attack, so it provides smooth service. Also, the benefit from this structure is that the real server can be hidden so the service can be provided continuously. It prevents damages from network cutting, reduces management cost, maintains the best performance, and increases convenient on management and maintenance. Stable and continuous service can be provided with managing network through MCS.

This paper is aimed at designing learning contents by applying augmented reality, as a plan to improve learning effect of learners who will study cultural properties. Learning cultural assets does not contain educational media which is able to be used for current learning. Even if is has the media, they are not fitting for the current educational situation, and most of them are simple. Insufficiency of educational media will make learners, who are interested in cultural properties and who are about to freshly learn cultural properties, far away from their desires to lean. Learning cultural properties is appropriate for a learning type to apply augmented reality. Accordingly, the author is aiming at developing educational media by applying augmented reality to learning cultural assets. In order to apply augmented reality, this paper examines concept of augmented reality and its application cases, accelerated learning factors and efficiency through the relevant pre-studies and development cases of educational application, and methods by which augmented reality is used for learning media. Based on these studies, this paper applied a learning theory stated in the pre-study, and designed learning contents by using augmented reality producing library. By means of the augmented reality based cultural properties learning contents, this paper plans to help learners who will study cultural properties and the relevant education, and to be a reference for designing learning contents applying augmented reality in the future.

Chroma key technique which composes images by separating an object from its background in specific color has restrictions on color and space. Especially, unlike general chroma key technique, image composition for stereo 3D display requires natural image composition method in 3D space. The thesis attempted to compose images in 3D space using depth keying method which uses depth information of Microsoft Kinect. Object was converted into point cloud type in 3D space after separating it from its background according to depth information. The image in which 3D virtual background and object are composed obtained and played stereo 3D images using a virtual camera. The research showed naturally composed stereo 3D images as well as the feasibility of applying stereoscopic 3D mixed reality image technology.

We generated a high resolution 3D object using a commercial DSLR camera and the low depth information of Kinect. High resolution depth map was obtained through camera calibration between the DSLR and Kinect sensor. 3D mesh model was created by the high resolution depth information and mapped with RGB color value. The experimental result showed that it is possible to create high resolution 3D object from the depth camera. This paper is expected to be applied to reality game graphic.
