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.

본 논문에서는 게임 사용자들이 요구하는 게임 경험치에 대하여 제안한다. 게임 경험치는 사용자들이 게임을 처음 접하는 단계에서 게임을 즐기는 동기 부여적인 측면과 게임을 진행함에 따라 게임 내 밸런스를 유지하기 위한 매우 중요한 요소이다. 게임을 즐기는 요소로서 게임의 재미요소에 대한 연구는 다양한 방면으로 진행되어 왔다. 그러나 게임 경험치 획득에 대한 구체적인 연구는 없었다. 게임 사용자들이 요구하는 게임 내 경험치 획득에 관하여 연구하기 위하여 사용자 그룹을 선정하여 사용자들이 각자 자기경험을 바탕으로 캐릭터의 레벨이 상승함에 따라 요구하는 경험치를 시각적으로 확인하면서 구체적인 값을 제시하도록 하였다. 이러한 결과는 향후 게임을 개발하는데 있어 사용자 요구를 반영하여 보다 일반적인 게임 경험치를 부여하는 기준으로 사용될 수 있다.

The purposes of this study are, firstly, to investigate the relationship between the online and mobile game players' psychological aspects (reference group, government regulation, game contents) and their game experience and overindulgence in games and, secondly, to suggest possible ways to reduce overindulgence in games. The implications of this research are as follows; Firstly, families and school authorities should strive to make sports and other pastime activities popular among peer groups rather than allowing online and video games to become only source of popularity among peer groups. Secondly, it is better for families members to establish a set of rules for controlling their children's time spent on online and mobile games rather than entirely forbidding the games. Family members should also strive to have more family conversations and to find a common source of interests. Thirdly, government should strive to develop policy responses to the overindulgence in games based on practical research and analysis. Fourthly, game makers should pay more attention to the components and expressions used in their games so as to draw game players' interests to the story and design of the games. Game makers also need to consider elements in their games that may potentially cause overindulgence in the development stage. Lastly, game players should strive to find new leisure activities besides online and mobile games that they can enjoy and have good experience with.

Group features such as group cohesion and consistency on appropriation(COA), which have been constructed through social interactions, should be noted for characterizing online game, especially, clan based massively multi-players online game (MMOG). This study attempted to identify the relationship between group characteristics and users' effectiveness of MMOG considering group experience. For this purpose, a research model was suggested: group cohesion and COA are variables for explaining group features, perceived use control is a variable for individual competency of playing MMOG, and perceived winning and perceived enjoyment are dependent variables. Moreover, group experience was included as a moderating variables for two relationships, group cohesion-preceived winning and COA-perceived winning. For the validation of this research model, 100 users for Sudden Attack which is one of very well known MMOG games were surveyed by questionnaires. Before survey, they were grouped into 10 teams and were played over ten times by team for perceiving group consciousness. In result, most hypotheses were statistically supported except the relationship between group cohesion and perceived winning.

In this paper, it is suggested that the elements constituting the gay empire are similar to the main pedagogical concept of John Dewey, a representative educational philosopher. I analyzed some factors that make up the concept of gamification by connecting them with the following five attributes. Continuity, interaction, interest, growth, and educational experience are the main factors that contribute to sustainability. Based on the theoretical analysis of the main concept, I try to find out the relation between the game and education, and understand the meaning of the gamification, not the game.

The purpose of this study is to investigate the actual situation of the surrogate games and win trading gameplays in e-sports leagues, and to insist on the creation of new regulations to punish them. The surrogate game surveys was conducted for 40 amateur users and 17 professional users in e-sports leagues. The survey was conducted in-depth interviews with a professional user to learn more about the actual situation of the win trading gameplay. As a result of the study, professional users had a high rate of experience with Gahz'rilla, and they would be able to increase their game rankings through Gahz'rilla. But they did not think Gahz'rilla is a surrogate game. Amateur users had a low rate of experience with Gahz'rilla and did not think they would be able to increase their game rankings through Gahz'rilla relative to professional users. Amature users tend to think of Gahz'rilla as a surrogate game. Both the users agree on the necessity of regulation on Gahz'rilla and surrogate game. Therefore, it is necessary to narrow the gap between the professional users and the amateur users by establishing rules for Gahz'rilla and surrogate game.

Online games are virtual space where it connects individual users through network connection to offer enjoyment of play games and game developer who service online games have to develop new contents and provide them to users to extend life of their service. Typically, in order to update new contents, all service companies have maintenance schedule to stop the game service for a while to update both server and client applications. Usually this process takes quite amount of time and users do not have any other choice but disconnected from server and wait until it is over. The purpose of this thesis is to describe the advantages of new design system which will allows users to continue to play the game even during the update. The main focus of this design is to make users feel more convenience in online gaming experience by move client from previous server to new server while users are still playing. If they can to connect current client with new server without any certificate validation process while users information from the client can automatically pass through to the new server, users may not need to experience maintenance for new contents update.
