Recently, standardization is essential strategic tool for a firm to preoccupy a market. Also WTO TBT(Technical Barriers to Trade) makes importance of standardization greater in telecommunication industry. Therefore countries, not to speak of firms, recognize standards essential strategy to preoccupy markets. In this paper, we will examine the standardization competition between a leader and a follower and their strategies through dynamic incomplete information game model.

In dynamic systems, such as social and economic systems, complex interactions emerge among its members. In that case, their behaviors become adaptive according to Changing environment. In many cases, an individual's behaviors can be modeled by a stimulus-response system in a dynamic environment. In this paper, we use the Iterated Prisoner's Dilemma (IPD) game, which is simple yet capable of dealing with complex problems, to model the dynamic systems. We propose strategic coalition consisting of many agents and simulate their emergence in a co-evolutionary learning environment. Also we introduce the concept of confidence for agents in a coalition and show how such confidences help to improve the generalization ability of the whole coalition. Experimental results are presented to demonstrate that co-evolutionary learning with coalitions and confidence allows better performing strategies that generalize well.

In addition to the quantitative growth of the games industry as a game addiction and social problems have also been increased. Addiction adoption of the resolution was presented to the fatigue system. In this study, flow and addiction affects 6 factors(self-control, positive expectations, interest, competition, positive self-efficacy, negative self-efficacy), depending on whether the adoption lag Flow to affect in any empirical analysis. This fatigue system effect on the game development and to enhance users' flow to do what strategies for theoretical and practical implications are to provide.

In the clustering protocol, lifetime of the cluster members radically decrease because frequency interference between clusters make every cluster member consume a lot of energy to maintain or increase its transmission rate. In this paper, we analyze the frequency interference among the clusters with the game theory which deals with resource bargaining problems between players, and present a rational power allocation strategy. Both the cases that each cluster tries to selfishly occupy and cooperatively share the resource are analyzed in terms of non-cooperative and cooperative games. In simulation, we compare the cooperative game with non-cooperative game in terms of the node lifetime.

The purpose of this study is to explore the contents and process of sexual harassment experience in digital games. We interviewed 12 Female gamers and analyzed their experiences through grounded theory. In the paradigm model, the core phenomenon was psychological confusion and influence. Various causal, contextual and interventional conditions have been identified. The strategies were 'direct and passive action', and 'anger expression'. The consequences were 'decreasing the value of game' and 'negative perception of Korean society and men'.

As Korean online game market is saturated, Korean online game companies are trying to push into North American market. In order to succeed in foreign markets, understanding of user characteristics in that country is most important. In this study, investigation on user characteristics has been performed using user DB from A online game and B online game. They are currently in service by M company in America. Connection time, payment, and royalty are analyzed as a results. Based on the analysis, several advance strategies into North America are suggested. This results could be very useful for Korean MMORPG company to try to push into North America.

In this research, we analyze change of directions and issues in future game industry. We start to analyze change of game contents and platform about impact of game industry under the digital convergence, and then we spread out a point of view about game user, game company, distribution of game industry over the length and breadth of game industry. In this paper, we analyze the future state of changing and the issues in online game industry under the digital convergence. For this research, we develop the on-line game industry's changing scenario. On the basis of the issue analysis about the future of the On-line game industry, we aim to provide some implications for business strategy of on-line game companies and policy of the government.

This paper investigates the influence of social networks on the satisfaction and loyalty of online game users. We gather the resulting questionnaires written by all respondents and compare social networks of users in the online game world. Social networks of online game users influence a sense of community. In consequence, the community sense influences the satisfaction and loyalty of online game users, respectively. Therefore, the companies which produce an online game and provide various services to users should consider the social networks and communities of their game users. Especially they have to try to manage the users who are the opinion leaders of the online game. If the companies make good relationships with users who are the opinion leaders of the online game, they would easily improve the loyalty of ordinary users by performing word-of-moth marketing of the users' opinions concerning about the online game.

In this paper appears that in this extremely attractive and growing services segment, academics, as well as practitioners, would benefit from investigating the relationships among the players' loyalty, word of mouth and flow, and the impacts of several other key game-related constructs on consumer behavioral intentions. A conceptual framework is proposed and a structural equation model is developed. This paper develops the exploratory LISREL model for identifying the factors affecting the players' loyalty for some specific brand of online games. The concept of flow, feedback, challenge, etc, are all introduced into the model, as the independent variables affecting the loyalty directly and indirectly. Statistical results show that depending upon the types of games, the configuration of structural equation model is a little different from each other, but overall results are very much intuitive in that challenge positively enforces flow, and flow strengthens loyalty. Other interesting results concerning game development strategy are also provided. It is hoped that this result might provide the useful guidelines for developing the successful online game contents. With a better understanding of the players' behavioral intentions, online game developers should be able to make adjustments in their development and marketing plans, providing them with a sustainable advantage over their competition.

Recently, the games on the market are getting rich and excellent in the category of design and productions. The style and production quality of cut-scenes also have achieved a continuous development, so how to stand out from multiple designs and gain popularity always acts as a challenge to designers. However, such design strategy up to developers will be failed to judge whether or not design achievements are loved by players and thus cannot meet rapidly changing market demands on both in a quantity and quality. Therefore, this study holds that cut-scene design for video games must set out from user-centered design(UCD). According to literatures with respect to product market, we know that Market Pull imposes far more impacts on success in bringing new products to the market than the technology Push, hence players actually determines the success of a game in competitive game market. This study will help to enhance the immersion of playing game, including the interest and standing out the designer's message without distorting the original impression in the game publishing environment.
