New game systems have emerged with the rapid growth of Korea smartphone game industry. Especially auto battle system introduced in RPG which is the most popular genre, which has brought a significant change in the understanding of the computer games. To understand this change, it is necessary to look at what circumstances did emerge auto battle system. What is important here is the smart phone as the technical apparatus which defines the presence of a smart phone game, and the use pattern of the smart phone. the technical device and Its use pattern are affecting the activity of the user how to play the game, game developers are to create the game system according to this play style. By examining the appearance and growth of this auto battle system, we can confirm that the micro changes in the game system, reflect changes in the present form of a computer game. This fact will widen the understanding of the history of computer games.

Game producers provide their products and service to users. But the need and desire of users change in many ways as time goes. But game Co. Ltd is difficult because of the capital and the technical identities for providing characteristic products and service etc. Specially, the FPS game which is popular among users is developed by game Co. Ltd as the maximum reflects desire of users, but is similarly developed in other companies FPS game by similar desire. This cannot accept from desire of a certain prospective customer furthermore, decrease of a loyalty customer and a new customer, and a company is difficult of market activity. Therefore, this research is to find of user's psychological needs by FPS game user after gaming on reusing intention and switching intention factors influencing. As the result, the intention of satisfaction and re-use for FPS game is 84.9%, the conversion intention to special force game is 9.6% and the conversion intention to the game of Sudden attack is 5.5%. It shows that desire of the user for certain games is changing.

This study tried to find the source of the success of on-line game sites and the way how the absorption and the satisfaction would have the relationship with the intention-to-use of on-line game sites. The primary purpose of this study is to establish the empirical model on the determinants of on-line game sites. The research model of this study will have insights which are trigger to the higher dimensions on the model and to the importance of the evaluation criterions of game sites. The suggestions of the study are as follows. First, the precedent factors of research model were tested for the commonality with explorative factor analysis and then tried the confirmative factor analysis. Thus, the determinants in this model will be used for further study without an evaluation. Second, the factors which have a most significant effect on the mediating factor like the absorption are a skill of user and an activity of community. Furthermore, the information quality of game sites was most significant in the satisfaction of user. Third, the most factors which included in the research model were significant to intention-to-use, however, the system quality did negatively significant.

This study analyzed social development and self-efficacy in use of internet in adolescents. Subjects were 510 7th, 8th, 10th, and 11th grade students in Daegu. Instruments were the modified Activities Questionnaire for Students (Heitner & Erica, 2(02), the Personality Inventory for Youth (Heitner & Erica, 2002) and the Self-Efficacy Scale (Song, 1998). Findings were that (1) male students use more synchronous (multi-game) but female students use more asynchronous (e-mail) and asocial (web-surfing) internet activity. (2) Synchronous social internet (multi-game) users were more social and more efficient than asynchronous (e-mail) and asocial (web-surfing) internet users.

Most current games are composed of simple operations without a user's actual movements. because they are made up of only virtual space. For that reason, many side effects arise on a user's body and mind. The Alternative Reality Game(ARG) is new game genre that has an effect to mitigate side effects caused by activity on a virtual space. This new kind of game genre can be instrumental role in creating a greater social intimacy and a higher tendency to cooperate that potentially reaches beyond the game context. In this paper, we suggest a real implementation of ARG using mobile devices and NFC tags. In addition, a noble editor for creating an ARG and a game launcher based on mobile device are suggested.

We have developed a serious game for the elderly named 'Paldokangsan 2' in 2012 as a next version of 'Paldokangsan 1'. 'Paldokangsan 1' was a walking game for two people using controllers of armrests and footboards with PC. 'Paldokangsan 2' had additional purpose to assist cognitive, physical, and psychological functions of the elderly. Especially, walking activity was implemented in a way that a player walks around the old traditional market place in 1970's while remembering and choosing healthy food to buy. We also developed two mini games for the elderly and people with functional disability with the similar purpose as 'Paldokangsan2'. 219 older adults (age$$\geq_-$$ 65) recruited from Asan city community center participated in the study. The result showed that the game play exerted positive effects on memory, concentration and vitality of the elderly.

In this paper, we proposed the education program using Scratch as an alternative activity for the remedy program of game addiction. We tried to find the solution through computer and game that affect the problem of game addiction. We choose the high-risk students about game addiction disposition and took a programming lesson for educational game development with consultation class. We also analysed the effectiveness of our remedy program. We found the positive results between before and after the program and we analysed that game connectivity rates were decreased during recess time. In interview and observation about students, we found that the students were changed to the positive tendency about game addiction. We expect this program will give many help for solving the problem of game addiction, if this research is applied to the regular class in elementary school.

Among the various security threats in online games, the use of game bots is the most serious problem. In this paper, we propose a framework for user behavior analysis for bot detection in online games. Specifically, we focus on party play that reflects the social activities of gamers: In a Massively Multi-user Online Role Playing Game (MMORPG), party play log includes a distinguished information that can classify game users under normal-user and abnormal-user. That is because the bot users' main activities target on the acquisition of cyber assets. Through a statistical analysis of user behaviors in game activity logs, we establish the threshold levels of the activities that allow us to identify game bots. Also, we build a knowledge base of detection rules based on this statistical analysis. We apply these rule reasoner to the sixth most popular online game in the world. As a result, we can detect game bot users with a high accuracy rate of 95.92%.

In this paper, a mechanism for spectrum allocation in overlay cognitive radio networks is proposed. In overlay cognitive radio networks, the secondary users (SUs) must first sense the activity of primary users (PUs) to identify unoccupied spectrum bands. Based on their different contributions for the spectrum sensing, the SUs get payoffs that are computed by the fusion center (FC). The unoccupied bands will be auctioned and SUs are asked to bid using payoffs they earned or saved. Coalitions are allowed to form among SUs because each SU may only need a portion of the bands. We formulate the coalition forming process as a coalition forming game and analyze it by game theory. In the coalition formation game, debtor-creditor relationship may occur among the SUs because of their limited payoff storage. A debtor asks a creditor for payoff help, and in return provides the creditor with a portion of transmission time to relay data for the creditor. The negotiations between debtors and creditors can be modeled as a Bayesian game because they lack complete information of each other, and the equilibria of the game is investigated. Theoretical analysis and numerical results show that the proposed auction yields data rate improvement and certain fairness among all SUs.
