Virtual reality means artificial reality which can be realized through five senses. Observation can be possible as virtual reality leads to that human being are at tele-existence. In addition, human beings can have teleconferences and do cooperative work in the virtual reality environment. If we hear 3D sound in the space of virtual reality, we can almost realize such operations. 3D sound is essential to realize virtual reality. A variety of factors need to be considered such as intensity of sound delivered to ears, frequency spectrum, phase of sound and auditorial senses to implement 3D sound. In this paper, the information of the software can be transferred to the hardware, the hardware can be controlled, then 3D sound for teleconferences can be implemented in the virtual space, using Head Related Transfer Function (HRTF). Furthermore, it can also apply to 3D games.

Although the history of the game of Go is more than 2,500 years, the theoretical studies of Go are still insufficient. In recent years a lot of studies using Artificial Intelligent (AI) have been conducted, but they do not provide the prominent theoretical reality. We applied traditional Principal Component Analysis (PCA) algorithm to the Go openings, which are the early stage in Go, to analyze them especially focused on the Go game records of the Korean top 10 professional Go players. We firstly analyzed the number of most significant eigenvectors capturing most of variance. Experimental result shows that among the 361 eigenvectors the eight most significant eigenvectors capture most of the variance (96.2%). We secondly used PCA classifier with Euclidean distance to recognize a pro player's opening to a class obtained from the training openings. Result shows that the best average recognition rate of 22% is so much lower than the recognition rates reported in face recognition research.

The MORPG(Multiplayer Online Role Playing Game) is one of the popular online game genre that its game play is more addictive and it has longer playing time compared with casual-style online game. This property makes it possible for game company to derive stable revenue for a long time other than casual- style online game. So far, developing MORPG has been popular on PC platform and now it has been started on a smart phone platform due to advances of hardware technologies and MORPG gives a new game experience to smartphone users. In order to make a new MORPG on smart phone platform, we have to design various use scenarios that are characterizing users’ behavioral actions in the game. It is time-consuming but we could save the design time if we reference to those of MORPG on PC platform. The paper proposes systematic user play scenarios for MORPGs on PC platform by characterizing 「Dungeon & Fighter」 and 「League of Legends」 which are the most popular MORPGs on PC, these days. We present the whole user scenarios with flowcharts showing the characteristics of all possible users’ actions in the MORPGs. When we make a new MORPG based on a smart phone platform, our results will provide with an effective design guideline for its game design.

The international and domestic revenue keep growing constantly, and nowadays the international casino game industry is getting upgraded utilizing IT technology. In contrast, due to many constraints and limitations, Korean IT society has not paid attention to the casino IT area. Slot machine is one of popular gaming systems in the casino.

The location and intensity of the environmental light source is computed with Android mobile device, which is used for AR image rendering. The experimental results show that using the surrounding illumination enables us to generate more realistic rendering images with the shadows reflecting the environments.

교육은 항상 세간의 관심거리다. 대한민국 국민이라면 모두가 교육에 관한 한 각자 나름대로 일가견을 가지고 있다. 누구나 교육부장관이고 누구나 교육대통령일 만큼 교육은 모든 이의 관심을 불러일으킨다. 그동안 우리 교육에서 사교육과 공교육은 서로 대립각을 세워 왔다. 각자 스스로의 의지로 그렇게 했다기보다는 각각의 본질과는 무관하게 외부 영향에 의해 서로 대비되어졌다. 공교육과 사교육이 상호 보완제로서의 기능보다는 대체제의 관점으로 제로섬 게임에 매몰되어 왔던 것이다. 이러한 ‘교육 정글’ 속에서는 온전한 교육의 본질을 회복하고 추구하는데 한계가 있을 수밖에 없다. 학교폭력이나 집단따돌림, 청소년 자살과 인간성 상실 등 여러 교육 문제의 근원은 사교육에 있는 것이 아니다. 오히려 교육의 본질과 인간 존재에 대한 본원적인 질문을 배제한 채 기능적이고 도구적으로 시행되는 교육행위 자체에서 기인한다고 볼 수 있다. 이제는 사교육을 바라보는 시각을 새롭게 재정립할 필요가 있다. 이를 통해 사교육과 공교육이 각자의 특성을 살리면서 서로 공존(共存), 공생(共生), 공영(共榮)할 수 있도록 배움학적 상상력을 드러내는 것이 미래교육의 비전이며 추진 방향이다.

게임물 이용환경의 융합 및 글러벌 서비스에 따라 게임물의 자율등급분류제도 도입에 대한 본격적 논의가 예상된다. 자율등급분류는 시장의 필요에 따른 것이지만, 지금까지는 규제 우위의 정책에 따라 그 논의를 쉽게 진행하지 못한 면이 있다. 더욱이 게임은 IT기술의 발전에 따른 규제정책으로 인하여 합리성을 담보하지 못하였다. 본고는 플랫폼 환경의 변화에 따른 게임물 등급분류제도의 개선이라는 접점을 찾고자 하였다. 그 접점은 오픈마켓 자율등급분류제도이며, 최종적으로는 전면적인 자율등급분류제도라고 판단된다. 자율등급분류제도가 가장 합리적인 게임규제이며, 이를 위해서는 사후관리를 통한 등급분류에 대한 가치가 훼손되지 않도록 노력해야 할 것이다. 사후관리는 공적기구에서는 물론 자율등급분류기구에서도 엄격하게 진행될 필요가 있다. 다만, 엄격한 사후관리가 자율등급분류의 취지를 훼손하거나, 등급분류의 자율성을 침해하는 것은 바람직하지 않다고 본다. 이와 같이, 자율등급분류의 제도적 취지가 달성된다면 사업자는 게임물의 창작활성화를 도모하고, 이용자는 게임의 내용정보를 자세하게 확인할 수 있게 된다. 이로써 게임물이 갖는 표현의 자유를 확대를 통해 새로운 문화를 향유하게 될 것으로 기대된다.

There are several “game testing techniques” to find bugs in game software. But they can not support game developer to correct errors easily and effectively in game development process. And also they are doing process according to game developer’s scenario and intuition at game company in these days. Therefore, to solve the above problem in this paper, this dissertation suggests a efficient testing techniques to judge the suitable generation of the auto-generate game map according to the game user’s playing and verify them TFD (Test Flow Diagram).

In recent years, with the successful growth and rapid overseas expansion of Korean games, Korea’s game industry has become the new engine for economic growth and positioned itself as the symbol of a successful cultural content. However, despite all this, the popular media has accused game as the cause of gambling and also violence. And every year the government is coming out with new regulations that are seriously affecting the whole game industry. Therefore, right now there is a need to introduce regulation to the game developers not as an object of condemnation or an object to be evaded. Regulation should be rethought and also measures should be taken to minimize it side effects. This study examines and tests the most recent regulations that were not suitable for games. And it shows the effectiveness and provides an alternative direction for game development.

Entry-level digital EEG instrument was launched at 2008 after that the digital EEG instrument was first introduced in the early 1990s. Because of cheaper EEG, many studies have been attempted using it. Among them, Special purpose serious games are getting heightened interest. Special purpose serious game is giving fun and meaningful knowledge simultaneously. This paper proposes acquiring EEG from EEG instrument, noise cancellation/separation of waves through FFT/analysis/concentrations calculation, HTML 5 game implementation/Client server design and sending of game result to user's browsers. Through this we suggests that the method in which performs efficient design and implementation of Network-based serious game using EEG. Future work includes that user can perform piano ensemble using network to draw user's fun and concentration. And experimental will be performed in piano school to prove that the students who have used our system before lesson shows great learning ability than the others.

Because of advent of social network, not only many applications have been introduced but also many relationships have been made newly and rapidly. That one of the biggest factors of being made many relationships is plurality of social network game. Moreover the researches of EEG based game are increasing along with cheaper EEG (electroencephalogram) devices. Through Brain biofeedback training, peoples can gain concentration degrees and postpone Alzheimer's disease which have been became an object of public concern in aging society. In this paper, we proposed SNS-based game using EEG. Using BCI we can understand the degree of user's concentration and it will be used in SNS-based game. Our EEG-based SNS game will be used to postpone Alzheimer's disease and the thanks of nature of SNS, people can be leveraged to using the game to compete to others.

Recently, the online and mobile game markets are enjoying a boom due to the wide use of the smartmedia, while the traditional video games have lost their popularities. While the use of the smartmedia based game increased, the game development companies participated directly in the circulation through the app market or the social platform. And, the competition of the related companies is expanded to the IT industry and SNS provider. As the success of the casual game led the development of online game industry, the social network game leads the development of mobile game industry along with the appearance of the smartmedia. In this paper, we analyze the key to success of the casual game represented by the Maple Story and Kart Rider and the social network game represented by the Anipang and Dragon Flight. From that, we drew the key to success that must have the succeeded game from the immersion view and we can provide some valuable strategies to the game company to succeed with the social network game.

The results of research based on historical events, Korea's game industry was divided into 9 steps including the dawn of the gaming industry(190-1984) and the historical significance of each step are derived.

This study investigates if the user's motivation for different game platform affects their tendency for game addiction. Game platforms profoundly relate to characteristics of game contents and the way games are played. While much game market expansion is driven by technological advancement of game platforms such as video and audio, the effect game platforms have on the way game is played is largely overlooked. A survey was conducted to compare PCs, consols, smart phones and smart pads as major game platforms and how users have different motivations for playing those platforms which is expected to associate with the degree of their game addiction. Six motivations were extracted - mobility, contents characteristics, media characteristics, sociality, game interface, and economic profitability. Across the four game platforms, all motivations except for economic profitability were proven to be meaningful predictors of game addiction.

Micro-transaction based payment model has been a key revenue model in social network game on mobile platform. The paper characterizes micro-transaction based payment models focusing on paid virtual game item, based on studies about micro-transaction based payment model on PC based social network games. The research will be contributed to building a systematized micro-transaction based payment model using paid virtual item for mobile social network game.

This paper is designed to investigate that the sound environment enlarged tactile sense through the game media impacts positively on the human body, cognition, and emotions, focused on two cases: elementary students' music appreciation lessons and elderly patients' music therapy. Learners using smart-device-based rhythm action games showed a rise of learning flow, learning satisfaction and learning assessment, and also music game had a positive effect on the treatment of the depression and self-esteem for elderly patients in nursing hospital. These results are because smart devices based music game provides the users environments which artificially extend human senses, give tactile and visual stimuli as well as auditory, and encourage behavior of touching interface in rhythm. In conclusion, we examine that game creates sensus communis immersive environment which effectively contributes to learning of students and psychological treatment of elderly people.

Today, social game is being one of the biggest growths on mobile and PC platform. This paper propose systematic user play scenarios for social games by characterizing 「FarmVille2」and 「AniPang」which are the most popular social games on PC and mobile, these days. We present the whole user scenarios with flowcharts showing the characteristics of all possible users’ actions in social game. When a game developer makes the game logic for a new social game, our results will provide with a design guideline for the game.

The purpose of this study is to derive factors affecting online game developers’ knowledge adoption in third-party online game user communities(OGUCs) and suggest a research model for the future empirical study. To accomplish this goal, we conduct an exploratory case study grounded on one of famous OGUCs operated by the third party company. Based on the heuristic systematic model(HSM) and interviews with three experienced online game developers, we identified three poster-related heuristic factors(reputation, experience, and participation level), three posting-related heuristic factors(the number of views, the number of comments, and the number of recommendations), and three posting-related systematic factors(knowledge quality, degree of disconfirmation, and degree of referencing) that influence developers’ knowledge adoption. We further developed measures for these influencing factors and suggested a research model with five propositions for the future empirical study. We conclude with discussing theoretical and practical implications, along with future research of the study.
