The game market has been converted into PC such as Microsoft X-box, SONY Playstation, and Nintendo, which have been called traditional game consoles. Recently, the mobile game market has been growing as the performance of mobile devices has been reduced. The expansion of the game market is a worldwide trend, and the discovery of game contents are causing many concerns for game companies. Known as the birthplace of animation and games, Japan uses traditional cultural contents to create many characters and game stories. China, which is a latecomer, is also working to find materials for making game contents using Chinese traditional culture. is one of the most successful games in China's online marketplace. The game is designed to allow game users to experience traditional culture by reproducing the images of the time period shown in the wall painting into a virtual space. In this study, I would like to analyze the story of the Buddhist scripture in the mural of Donhwang mural, a Chinese cultural heritage.

In the 2000s, the PC package game market has withered, but the internet based on-line game, the wireless internet based mobile game and high-powered console game market have been main stream. Among those markets, mobile game market has rapidly increased because it has 'mobility' that overcomes the limitation of time and area. But, unlike other platforms, mobile game user have to pay the higher price for download mobile game contents through the wireless internet and mobile game developer have to overcome the limitation of storage memory capacity.of mobile phone. Chiefly, the image data consume the storage capacity of mobile game contents, this paper present a technology to optimize image data for mobile game contents through analyzing type of compression method and image formats.

With the increasing use of mobile phones, mobile game is emerging as an entertainment for move. Furthermore, smart phone is widely spread, so mobile game market is rapidly growing. According to "Republic of Korea 2010 Games White Paper" mobile game market is growing annual average 10% or more, and is expected to reach $ 9.8 billion in 2011. It is almost doubled compared to 2007. It became possible to realize complicated high-capacity game with mobile phone developed to smart phone. And at the same time, mobile game is associated with Social Network Services (SNS) and is worldwide growing as a part of 'mobile life'. Apple launched an application open market, App Store, in 2008, and mobile game industry welcomed an innovative turning point. Global smart phone application market (App Store) is opened, so Gameday is able to launch mobile games easily to the global market getting out of the domestic market. In addition, Apple App Store has the structure of sharing their revenue with the developer with 7 to 3 which is more favorable terms for the developer compared to supply mobile contents to the mobile carrier who monopolized the market in the past. The largest proportion of the current App Store application is game, and Gameday has the opportunity to make a significant leap forward by keeping pace with the new environment changes.

An online game is popular topic due to the increased total online game market volume nowadays. Even though many studies on an online game are released, most studies have used survey method that reveal only section of the situation like a snapshot. For this reason, previous studies have a little limitation that does not show dynamically changing issues like a product life cycle and change in customer's satisfaction. Because of this, we researched on an online game with the system dynamic model which can show dynamic simulation to analysis time series data. We chose MMORPG (Massively Multi-play Online Role Playing Game) in sort of an online game because it has many absorbing factors and enthusiastic users. We assumed that the game developer is ready for updated version game and release that periodically and focused on dormant users who used to be enthusiastic about MMORPG and designed simulation model which analyze how to influence of update and CRM strategy on users. The simulation results showed that the update has positive influences to gather new users and hold established users and CRM strategies help to prevent dormant users from transferring to rivals to offer them re-absorbing factors. Through this study, we confirmed importance of update on a online game and suggested the necessity to introduce CRM strategy in an online game market.

This paper introduces a program structure that minimizes the client's business logic by reducing the client's specifications as a way of minimizing the limitations of online game platforms. The objective of this thesis is to design an online game that is based on a 3-tier client/server structure, and thus using this 3-tier structure to ultimately create an online Sutda game that anyone can enjoy. The progression of newly released games is highly based on the mobile market and the number of online games being launched is decreasing. As the mobile game market grows, more and more multi-platform games are being developed and target platforms within online games are greatly diversifying. Through these situations, this thesis minimizes the client's business logic through a 3-tier structure of application-middleware-database, and also proposes an online game client/server that allows three or more users to participate simultaneously through the server.

Competition among electric generation companies is a major goal of restructuring in the electricity industry, The trading system in an electricity market has been one of the most important issues in deregulated electricity market. This paper deals with comparisons of the major two types of the trading system: compulsory pool market and bilateral contract market. The two trading systems are compared quantitatively from the viewpoint of consumer's surplus and social welfare, This paper, also, proposes a unified model of Cournot and Bertrand for analyzing the mixed trading system of pool market and bilateral contract market. Nash equilibrium of the unified model is derived by criteria for participating in bilateral contract market. Numerical results from a sample case show that a mixed trading system of pool market and price-competitive bilateral market is beneficial to consumer from the view points of consumer's surplus.

This paper presents a game theoretic approach for power transactions analysis in a competitive market. The considered competitive power market is regarded as PoolCO model, and the participating players are restricted by only two generating entities for simplicity in this paper. The analysis is performed on the basis of marginal cost based relations of bidding price and bidding generations. That is, we assume that the bidding price of each player is determined by the marginal cost when the bidding generation is pre-determined. This paper models the power transaction as a two player game and analyzes by applying the Nash eauilibrium idea. The generalized game model for power transactions covering constant-sum(especially zero-sum), and nonconstant-sum game is developed in this paper. Also, the analysis for each game model are Performed in the case studies. Here, we have defined the payoff of each player as the weighted sum of both player's profits.

This paper presents a game theory application for analyzing power transactions and market design in a deregulated energy marketplace such as PoolCo. The conventional least-cost approaches for the generation resource schedule can not exactly handle recent real-world situations. A systematic tool using game theory for the market participants is presented such that it determines the net profits through the optimal bidding strategies including the strategies for the bidding prices and bidding generations. We treat this power transaction game as incomplete information one, which means each market participants does not know other's cost function. And the demand elasticity of the energy price is considered for the realistic modeling of the deregulated marketplace.

This paper presents a two stage game model which examines the effect of learning-by-doing and spillover. Increases in the firm’s cumulative experience lower its unit cost in future period. However, the firm’s rival also enjoys the experience via spillover. Unlike previous theoretical research model, a cost asymmetric market entry game model is developed between the incumbent firm and new entrant. Mathematical results show that the incumbent firm exploits the learning curve to gain future cost advantage, and that the diffusion of learning to the new entrant induces the incumbent firm to choose decreasing output strategically. As a main result, we show that the relative magnitude between the learning and spillover rate determines the market share ratio of competing firms.

This paper concerns the analyses of dynamic adjustments in noncooperative games where the market informations are given at discrete time intervals. During the game period, the market informations are given at discrete time intervals. During the game period, the inventories initially stored by players are to be released one day based to the completely competitive market so as to maximize each player's revenue, where players' parameters are unknown one another. Game results have shown that the continuous dynamic adjustment does not necessarily assure the better revenue, and if a player thinks that his parameter is underestimated by hig opponent, then he is better overestimate his opponent's parameter.
