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.

This research was conducted in an attempt to understand changes and growths of the self in on-line game world. Q methodology was used to investigate players in Mabinogi, which is an on-line game(MMORPG). Based on 57 behavior statements, Players distributed their changing experiences from when they were novices in on-line game world to the current state. In early start phase, they recognized that on-line game world was different from the reality. And they perceived their experiences in on-line game as separated from the real ones. However, as they spend more time in on-line game world, they began to realized that on-line game world is as real as the world because they function as an individual living in a society in both the game and the real world. They felt and learned that in on-line game life, they also need to follow the rules and order. In addition, trust and politeness were essential in order to live with other players. As time passed, the players realized that on-line game experiences have the same meanings and values as the real life ones. 3 types of self-changing patterns were found : Achievement change, Control change, and Relation change. The behavior patterns of the 3 types were then compared to Identify similarities and differences amongst them in psychological meanings and values in the on-line game life. This result illustrates that on-line game world can be defined as new behavioral setting or developmental context established by digital technology. In this new setting, people can experiment and understand their behavior patterns and also experience changes and growths of the self.

This paper uses counterexamples for solving reachability games. An objective. of the game we consider here is to find out a minimal path from an initial state to the goal state. We represent initial states and game rules as finite state model and the goal state as temporal logic formula. Then, model checking is used to determine whether the model satisfies the formula. In case the model does not satisfy the formula, model checking generates a counterexample that shows how to reach the goal state from an initial state. In this way, we solve many of small-sized Push Push games. However, we cannot handle larger-sized games due to the state explosion problem. To mitigate the problem, abstraction is used to reduce the state space to be che cked. As a result, unsolved games are solved with the abstraction technique we propose inthis paper.

Macro(automatic hunting) of mobile game is a program that touch the screen by defined rules like a game bot in PC online games, and it is used by make various ways like android application or windows application program. This gives honest users deprivation and make to lose their interest. Finally they would leave the game and gradually game life would be shorten. Although many studies to prevent these problems in PC online game are conducted, applying mobile game to PC's way is difficult because mobile games are limited to use the network and device performance is different with PC. In this paper, we propose a framework for macro detection by using the touch event information. A touch event on the mobile game is a necessary control command to the game. Because macro touches the screen with the same pattern, there is a difference between normal user's behavior and macro's operation. In mobile games that casual games are mostly, Touch event is the best difference that identify normal user against macro for a short period of time. As a result of detecting macros used in real mobile game by using the proposed framework it showed 100% accuracy and 0% false positive rate.

MMORPG로 대표되는 우리나라 온라인게임의 게임아이템 유형을 보면 대부분이 능력치와 관련된 것들이 많다. 이것은 게임아이템의 일부 기능만을 활용한다는 점에서 보다 적극적으로 게임아이템을 구성하고 그것에 유기적인 역할을 부여할 필요성을 갖게 한다. 이러한 필요성을 충족시키기 위하여 게임아이템을 인지심리학적 관점으로 연구는 것은 매우 유효하다. "게임아이템의 인지프로세스와 지식표상 모델"이라는 것은 인지심리학의 정보처리 과정을 게임아이템 사용자에게 적용하여 구조화한 것이다. 이러한 프로세스와 지식표상 모델은 게임아이템의 명료화와 인과적 플레이를 유도하기 위한 것으로 위의 필요성을 충족시킬 수 있다.

Wrestling is one of the popular events for modern sports. It is difficult to quantitatively describe a wrestling game between athletes. And deep learning can help wrestling training by human recognition techniques. Based on the characteristics of latest wrestling competition rules and human recognition technologies, a set of wrestling competition video analysis and retrieval system is proposed. This system uses a combination of literature method, observation method, interview method and mathematical statistics to conduct statistics, analysis, research and discussion on the application of technology. Combined the system application in targeted movement technology. A deep learning-based facial recognition psychological feature analysis method for the training and competition of classical wrestling after the implementation of the new rules is proposed. The experimental results of this paper showed that the proportion of natural emotions of male and female wrestlers was about 50%, indicating that the wrestler's mentality was relatively stable before the intense physical confrontation, and the test of the system also proved the stability of the system.

With device-to-device (D2D) communications, an inactive user terminal can be utilized as a relay node to support multi-hop communication so that connective experience of the cell-edge user as well as the capacity of the whole system can be significantly improved. In this paper, we investigate the spectrum sharing for a cooperative relay assisted D2D communication underlying a cellular network. We formulate a joint relay selection and channel assignment problem to maximize the throughput of the system while guaranteeing the quality of service (QoS) requirements of cellular users (CUs) and D2D users (DUs). By exploiting coalition formation game theory, we propose two algorithms to solve the problem. The first algorithm is designed based on merge and split rules while the second one is developed based on single user's movement. Both of them are proved to be stable and convergent. Simulation results are presented to show the effectiveness of the proposed algorithms.
