Computer Science Education has to be dynamically changed due to a change of information technology. This study aims to present the direction of development for computer science education according to compare a report of KEDI; Korean Educational Development Institute, twenty years ago with our latest investigation. In this research, nowadays the personal computer diffused at most home. Home is the main environment for students to use computer. Students demand new computing curricula and teaching method. The global tendency of computer science education focuses on the improvement of problem solving ability. According to our investigation, most students hope to learn the new computing skills through game-based learning. We present the unplugged teaching methods and simulation-based learning using EPL(Educational Program Langage). Of course it's important to be applied to school now. And it can be achieved just by national efforts alone.

A smart TV is able to show terrestrial broadcasting and also can be used as a computer -VOD, games, image communications, application utilities and so on. In order to carry out Smart TV business, it has to contains contents, platforms, network terminal unit. If ill-equipped with any of these aboves, it must cooperate with other licensee. Therefore, Smart TV business is necessary to cooperate with each business agent. In this paper, we will look into domestic/foreign country Smart TV market, policy, vitalization strategy, and suggest the application of big data analysis methodology for Smart TV vitalization method - 1) hardware infrastructure building based on cloud computing 2) Network upgradability acceptable traffic increase 3) Technical development cooperation between each licensee 4) Variable Smart TV contents supply 5) Cooperation with party interested individuals in using UX/UI for N-Screen, network traffic estimation may increase, customized supply smart contents for consumer in real time.

Through this thesis, I intended to analyze superhero action thriller through that achieved in art and box office after the film release. I would to access about it centering around directing viewpoint. of Christoper Nolan is evaluate as 'upgraded excellent action thriller'that have remarkable theme and excellent visual. Analysis of directing'll classify both contents and form. See about contents... theme of existential dilemma about the good and the evel, characters who is grew more powerful, and deeper than Batman series in old times. the fifth plot, especially dramatic plot by Joker's game, and various irony and motif. About form... efficient use of IMAX camera, prominence of action directing about car chase and fighting... better editing and music and art than former super hero series. The most important merit of is it's a philosophical theme. It is dipicted very seriously and successfully. First of all, the film has more advanced technique power and new directing style.

The motion capture system has shown its great potential as a new image expression means for handling such challenging tasks as realistic animation of humans or animals in motion, which cannot be handled by the existing key frame method satisfactorily, and also projects involving a large scale or a burdensome economic expenses. Its applications also has been intensified and widened in the entertainment arena including motion pictures, TV, advertisements, documentaries, music videos, etc. centering around games. Despite of these merits, though, a number of issues have been surfaced in the digital image expression utilizing the motion capture system, such as a burdensome amount of preparatory work, the needs for attachment of markers and for remedial corrections of motion data, and the lack of trained manpower. We would like to present in this paper a new direction for making the digital image production more efficient, based on the extensive analysis of prior image production projects that used the motion capture system.

OneNAND flash is a high-performance hybrid flash memory that combines the advantages of both NAND flash and NOR flash. OneNAND flash has not only all virtues of NAND flash but also greatly enhanced read performance which is considered as a downside of NAND flash. As a result, it is widely used in mobile applications such as mobile phones, digital cameras, PMP, and portable game players. However, most of the general purpose operating systems, such as Linux, can not exploit the read performance of OneNAND flash because of the restrictions imposed by their virtual memory system and block I/O architecture. In order to solve that problem, we suggest a new approach called virtual I/O segment. By using virtual I/O segment, the superior read performance of OneNAND flash can be exploited without modifying the existing block I/O architecture and MTD subsystem. Experiments by implementations show that this approach can reduce read latency of OneNAND flash as much as 54%.

User interface is one of important factors to enhance one's presence in virtual reality systems. Due to the performance improvement of hardware, the virtual reality system is extensively utilized in games, broadcastings, educations, cultural contents, and so on. And, it is enlarged the necessity for researches on mobile interface to control the virtual reality system guaranteeing user's unrestricted movement. In this paper, we present a mobile interface, ZA sensor which is constructed with a Zigbee module and a Accelerometer to control the virtual environment. And, we propose a method of constructing the virtual reality system using the ZA sensor as a input device and practical applications of the system.

As the paradigm of the Fourth Industrial Revolution is expanding, VR devices and their contents industry are drawing more and more attention as the digital devices of the next generation. Of the realms of VR contents, $360^{\circ}$ 3D videos are receiving the most attention in the field of media, and they are being utilized by Google as educational contents. As such, this research analyzes actual condition of use and motivation of using corresponding contents through survey of $360^{\circ}$ 3D video users. Results show that the most utilized platform is Youtube, and the genres which the respondents have used or are willing to use turned out to be Games and Movies.

The objective of this study is to plan a space for senior citizens using digital contents as the measures for securing the cultural diversity by paying attention to culture of senior citizens. For this, this study theoretically examined digital contents as physical/social/psychological aging of senior citizens, space only for senior citizens, and culture of senior citizens. The research method used an in-depth interview. The results of this study are as follows. The senior citizens wanted the new play culture besides cultural programs operated by the existing spaces for senior citizens, and they also showed high preference of digital contents such as personal media and game. Especially, the senior citizens had an expectation that such digital contents would be helpful to smooth communication between family members. Based on such results, this study suggested a digital based culture spaces for senior citizens.
