As a new entertainment and social way, online games now have a huge and increasing user group, so it is of great significance to identify the data stream of online games. Using the excellent nonlinear fitting ability of BP neural network and the advantages of global search of genetic algorithm, the initial weights and thresholds of BP neural network are optimized, and the BP neural network model optimized by genetic algorithm is established. The muti-dimensional input information is proposed to identify online game data streams. Through the experimental simulation, it shows that the selected muti-dimensional information and the established model can be well applied to online game stream recognition.

Net neutrality, which has not been a problem, has recently become a problem for ISPs (Internet Service Providers), and their complaints have been paid by domestic platform companies, but overseas global IT companies such as Google and YouTube, generate huge revenues from domestic markets. In this situation, domestic IT companies claim that it is natural to impose more expensive charges or restrict speed on users who generate huge traffic. On the other side, however, the telecommunication network has become an essential public good that is essential to our everyday life, and because it has been given a monopoly position by a private company to efficiently respond to the explosive demand for telecommunication services, It is necessary to provide equal and universal service and fulfill public duty. In this paper, we deal with the network neutrality problem, focusing on the price elasticity between the CP (Contents Provider) and the ISP, rather than the user who is one side of the two-sided market for the already saturated satellites communication market. We present a game model that determines the optimal price for each platform by Nash equilibrium and analyze how the net neutrality affects CP according to the change of exogenous variables through the proposed game model.

이제는 모바일 마켓순위에서 많은 게임이 높은 점유율을 차지하지만 점유율을 오랫동안 유지 하는 것은 쉽지 않다. 게이머를 끌어당기는 중요한 요소는 게임 재미(Game Fun)이고, 게임을 재미있게 만드는 가장 중요한 요소는 게임 난이도이다. 하지만 게임 난이도를 디자인하는 것은 매우 어려운 일이다. 본 논문은 두 개의 연속적인 컨볼루셔널 레이어를 사용한 컨볼루셔널 신경망과 SVM 분류기를 이용하여 게임 시 플레이어의 얼굴 표정을 실시간으로 검출하고 판단한다. 실험 결론은 CNN을 이용한 표정 시스템은 게임 play-time 및 score를 늘릴 수 있고, 게임 재미를 증진시키기에 도와 준다고 증명하였다.

픽셀 아트는 낮은 해상도와 제한된 색 팔레트를 가지고 영상을 표현한다. 픽셀 아트는 낮은 연 산 성능과 적은 저장 공간을 가지는 초기 컴퓨터 게임에서 주로 사용되었다. 현대에 이르러, 픽셀 아트는 예술이나 퍼즐, 게임과 같은 다양한 분야에서 찾아볼 수 있게 되었다. 본 논문에서는 게임 캐릭터 영상을 입력으로 받는 픽셀 아트 생성 모델을 제안한다. 기존 방법 과는 달리, 합성곱 신경망(CNN:Convolutional-Neural Network)를 픽셀 아트 생성 목적에 맞게 변형하여 이를 이용하는 방법을 제시한다. 기존의 합성곱 연산 후에 upsampling 과정을 추가하여 픽셀 아트가 생성될 수 있도록 하였다. 네트워크는 ground truth와 생성된 픽셀 아트와의 평균 오차 제곱(MSE:Mean Squared Error)을 최소화해나가며 학습을 수행한다. Ground truth는 실제 아티스트가 생성하도록 하였고, 이미지 회전과 반전 기법을 이용하여 augumentation을 수행하였다. 생성된 데이터 집합은 학습, 검증, 시험 데이터로 나누었다. 이러한 데이터 집합을 기반으로 감독 학습을 실시하여 픽셀 아트 생성 네트워크를 학습하였다. 학습 모델의 학습 과정과 학습 정확도를 제시하고, 시험 데이터 뿐만 아니라 다양한 영상에 대한 픽셀 아트 결과도 함께 제시한다.

This paper introduces the implementation of runtime synchronization method when mobile network is broken during the game play. In case of network failure, the game is restored using the saved play record. Before the network failure, the previous game play is recorded in the server. The runtime synchronization is performed using the recorded game play in 2-times, 4-times, 8-times and 12-times according to the paused time and the game is played continuously. Using the proposed method, the user can play the mobile game uninterrupted. The project mobile game is implemented, and shows the effectiveness of the proposed method.

This study has investigated on the obstacles to the production of social network games. It also tried to find their production tools in order to remove existing obstacles, which will guide to design and create new production tools. The new production tool is designed to make it easy for Terrain, UI, and Object tools to be used for essential functions, game linkage, and testing. The detailed explanation about the structure design and functions of the new production tool is also written and added for better understanding. To test its functions, texture of the animation application was printed on top of the production tool. The test result showed stable processing speed. I also made a 􋺵Farming􋺶 trial-game to test how easily social network games can be developed. As a result, more stable framework, which could not be made without production tools, was able to be designed and even the time spent on developing it became shortened.

Open source "Boost Lib" in this paper is to propose a distributed processing architecture of the game server, and the server models the whole vertical extension of the load generated by a specific process, the load on the game server for both the horizontal scale model of a typical distributed system, Dispersing the processing game process, and corresponds to the load.Multi-server architecture is distributed into the game world to the local level. Since the distributed server to process by integrating the entire process of the game server divided area, when only a specific process, the throughput increases a load to cause the load itself is transferred, the entire game server the local server is slow. If the load is generated in the specific process in the multi-server architecture must scale the game server or the game server cluster. However, while the load of a particular server extensions are uneconomic to process less meaningless. Therefore, the conventional method of dispersing uniformly without separate operations for all the processes are dispersed to the more process unit will be more and better ways to game services in general reliable service throughout is possible. for all the processes are dispersed to the more process unit will be more and better ways to game services in general reliable service throughout is possible.

This study aims to examine what factors affect the use of promotion advertisement of Social Network Game(SNG). The results show that the user's age has significant impact on privacy concern. The user's sex and SNG time don't make a difference to privacy concern. Privacy concern has an influence on the advertising attitude of SNG user's. As user had more privacy concern, user has lower attention and credibility, higher annoyingness. User's perception for usefulness, credibility of mobile game advertising and SNG time are proved to be effective factors on the use of SNG promotion advertisement.

Recently, mobile Social Netwrok Game(SNGs) including characters have emerged in the game market. Basically, it is based on not only the mobile environment and technology but also the form and concept of SNG. Most characters of mobile SNG take characters which have the role of avatar or non-player character. This kind of characters allows own their characteristic to create and design them based on the mobile and SNG system. Therefore, the goal of this paper is to analyze character design with the elements of mobile graphic such as visual, sound, motion and so on. Then we would discuss the features of character design for mobile SNG and comment the limits and consideration for effective design. For this research, the first of all we would discuss the concept and theory of mobile SNG and the design elements for the game characters by the publications, including thesis, articles, and books. Seondly, this paper will be focused on character examples in 20 mobile SNGs which are selected in top selling and analyze them. Finally, we would discuss the characteristics of mobile SNG character and the methods of possibilities and considerations for effective design.

Evolutionary computation is a powerful tool for developing computer games. Back-propagation neural network(BPNN) was proved to be a universal approximator and genetic algorithm(GA) a global searcher. The game of Tic-Tac-Toe, also known as Naughts and Crosses, is often used as a test bed for testing new AI algorithms. We tried to recognize the strategic fitness of a finished Tic-Tac-Toe game when the parameters, such as a sequence of moves, its game depth and result, are provided. To implement this, we've constructed an evolutionary model using GA with back-propagation NNs(GANN). The experimental results revealed that GANN, in the very long training time, converges very slowly; however, performance of recognizing the strategic fitness does not meet we expected and, further, increase of the population size does not significantly contribute to the performance of GANN.

This paper is conducted to support Korean game development companies to enter the MSNG market in China. According to preceding researches, the life-cycle of MSNG is under 3 months. Short-term of the MSNG's life-cycle raises the problems of low profits or deficit of companies managed to enter the Chinese market. Therefore, it needs to lead MSNG users to continuos use to extend the life-cycle. The plan to extend the life-cycle is likely to be a critical factor to be survived in Chinese market. The commitment is considered as the factor to make usage of MSNG longer by researchers. This paper also infers that the plan to keep MSNG user's commitment continuos develops their perceived functional value, emotional value and social value, with the reasonal, emotional and psychological point of view. We make a effort to reveal the relationships among factors through 318 data from Chinese MSNG users. Futhermore we would like to suggest that the companies consider continuos usage intention of MSNG users as the critical factor which makes a profit based on the result of this survey and propose the direction of future researches from the limit of this paper.

On July 30, 2012, Kakao Talk of Kakao Co., Ltd has pioneered a mobile platform SNG market for the first time in the country along with the launch of ‘Kakao Game Center’. While Kakao Talk has released a puzzle game called ‘Anipang’ at the time of launching the Kakao Game Center, it has recorded a DAU value exceeding 8 million at the most by dominating the domestic mobile game market for smart phones right after being released. However, a sudden decrease of DAU was shown starting September 4th which is not even two month after being released and the defection of DAU continues to occur. This is a condition which is different from the Facebook SNG which is a computer platform based SNG where the DAU is steadily maintained until now. This study attempts to analyze the cause of such conditions through the comparison between Facebook SNG and Kakao Talk SNG representing each of computer platform based SNG and mobile platform based SNG to present an important reference point for the game creators who are preparing for the participation of mobile platform based SNG industry in the future through this analysis.

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.
