Although many theoretical and empirical studies consider violent games, general causality between violent games and aggression or violence is ambiguity. To overcome such limitations, we try to identify the focal points of violent games. This study aims to explore the critical debate about violent games from research result in terms of heading in opposite directions. Furthermore, we analyzed the discourse of the violent game based on catharsis theory and cognitive neoassociation theory. Catharsis theory predicts that 'venting' aggression through exposure to violence will reduce the risk of later aggressive behavior. On the contrary, cognitive neoassociation theory posits that aversive events produce negative affect such as aggression. Several recent studies found little evidence for a relationship between violent games and aggression or violence. Given that aggression is not negative, it is reasonable to study the potential benefits of violent games. Therefore, we suggested several ways to application the violent games based on prior literature.

This paper aims to introduce an overall game application as an effective tool for various corporation-related purposes. This work lies in the communication and sharing frameworks: Serious games, Advergames, Gamifications. We first discussed on the serious games, advergames, and gamification for both employee and customer based on previous literature review. Second, we synthesized the key features of game applications benefits that make them promising to be used for corporation purposes. All three of them, it will be efficient not only corporation (employee training & education, advertising & marketing) but also customer (information delivery capability, communication & feedback control etc). Moreover, various game-related factors are more effective means rather than antecedents of other media such as Internet and TV. Overall, game applications play a significant role in influencing the intention to corporation’s goals. Finally, implications of applications benefits for corporation purposes and future direction for research in this area are discussed.

The market of the smartphone game has been changed rapidly which can be seen in the online PC game, ‘SNG’ and became popular among the game lovers. In the same way, ‘Kakaotalk’ has also been appeared suddenly. Therefore, in this research work, we figured out the exploratory factors that affect the intention of use of smartphone users and these effects can help future works on games to those who are doing research on it. In our research method, we reviewed the preceding related researches about the intension of use of smartphone users. Based on these researches, we have extracted factors for suggesting research model and then verified the hypothesis with actual analysis to find out which factors are affecting the intention of use of smartphone game users. The factor and reliability analysis have done in order to examine the validity and reliability of the questionnaires used in this work. As the result, popular genre, character, sequence of hit etc. are affected positively on intention of use of smartphone game users but there are no meaningful effects of game developers. Due to such research, it can be helped to the related game developing academic and industries researchers on intention of use of smartphone games users.

Additionally, we developed interactive game contents which have been added function of visual and auditory to be effect on education to users. In this paper, this research will provide information for the development of interactive game contents using IoT. Thereby be achieved through convergence with other things, the functional effect of the interactive game provide the understanding of the new trends.

The purpose of this study lies in figuring out the factors of how soldiers' digital games experiences make influence on combat power improvement of the military.. For this study, based on the technology acceptance model, we have analyzed how causation is formed between self-efficacy and the collective-efficacy, perceived usefulness, perceived ease of use and the behavior intention. As a result of validating structure equation modeling targeting the sample of 101 soldiers, self-efficacy on digital game has a significant impact on perceived usefulness, perceived ease of use and the behavior intention. This result implies that soldiers’ digital game experiences have compelling relations on improving combat power of individual, which is a component of the military combat power, and the members of the organization. This study’s result offers an insight for implementing and utilizing small unit war game cyber combat system, which is based on digital games related to improving the military combat power in the future

In online game, Game-bot is a kind of AI based software which performs laborious tasks for a game-player to accumulate resources such as experience, in-game items. The game-bot causes serious problems of balancing and other game-players’ play in the game. So, detecting and avoiding game-bot’s behaviors in online game is one of the important issues in live game management. This paper proposes a study on a player reaction in MMORPG environment focused on two games of 「TERA」 and 「Knight Online」. We first characterize core game-elements to affect a player’s reaction in game environment change and finally propose a template of a player’s reaction in the game environment change. The paper will contribute to detect a behavior of a game-bot in online-game, effectively.

This study examines the general assumption that serious games can bring about positive effects for purported social changes. The interactive nature of the serious game was thought to be one of the distinctive aspects of the medium as compared with other traditional non- interactive media. To explore whether the interactivity of serious games yields different psychological influences, we conducted an experimental study with a serious game whose narrative concerns the environmental issue, EcoFriendz (N=40). The results illustrate that those who played the video game perceived themselves to be more aware of the environmental problem than those who read the same narrative in a non-interactive text format. Also the game players were more willing to carry out measures to deal with the environmental problem.

Play for mankind was evolved into the current era of digital media found in a monitor, so-called ‘game’. Along the current trend of broadly expanding the users of game, the collision is frequently occurred from the issues associated with balance between the proper and reverse function melted in a terminology, “game”. However from the perspective of writer, the existence of game, if it is in an inseparable relation with the mankind, should be fully accepted, rather than be blamed, therefore, our life should be settled down as a cultural trend in the age of “cultural prosperity”. The writer also realizes that game should be settled down as advanced cultural contents as high-edge, comprehensive cultural arts. Therefore, the writer strongly argues that the convergence of engineering and humanities imaginations should be achieved for the unity of knowledge in game industry. Humanistic element is required for the convergence of engineering and humanistic imaginations. In-depth consideration is highly required to find an approach how two afore-mentioned elements, that are totally different each other but in the neighborhood, are to be well-mixed and integrated for story-telling, which is the ultimate motivation for this study. Therefore as a result, a key to dilute the dysfunctional issues associated in game industry was the convergence of humanities; accordingly, this study was to seek a methodology what humanities can be integrated with the components of game, such as character, event and background.

This paper presents a parallel kd-tree traversal algorithm based on the parallel binary radix tree construction scheme proposed by Tero Karras in 2012. In his paper, Tero Karras proposed parallel tree construction algorithm which can maximize the utilization of GPU threads, but implementation and analysis of kd-tree are not fully discussed. This paper aims to fill the gap for the specific kd-tree cases. As an application for the kd-tree traversal method proposed in this paper, the proposed method has been implemented with NVIDIA’s CUDA framework and tested on NVIDIA’s realtime raytracing library, OptiX. As a result, the proposed method can construct tree structures within the requirement for realtime process, but still needs specialized spatial caching data structure like the “primitive tree” for highly detailed meshes to handle spatial queries as fast as to visualize implicit surfaces under OptiX framework. However, the proposed method can be applied to dynamic collision detection and manage scene and object information for game applications thanks to its fast tree construction process. Also, realtime raytracing can be applied to game applications based on this study.

Prevalence of children with developmental disabilities has increased the need for a variety of educational and therapeutic interventions for children in the study of the subject has increased according to the load. in this paper, the review of the developmental disability characteristics and teaching methods are based on this proposal of realistic experimental serious game contents using AAC(Augmentative and Alternative Communication) method because we make up for the conventional interventions and increase participation and motivation in learning. In this paper, we improve the area said to be the motivation and commitment to develop the content by using a realistic experience for users experiencing at present a pervasive developmental disorder of language development in the paper. In particular, we shows the effectiveness of the improved speech area through the use of this serious game content through real experiments with children with developmental disabilities.

The purpose of this study was to make the sea with rending of ocean by using the proper algorithm for an emotional online game. We used statistical model to make the sea in this study. In measuring the wave height, we used Fast Fourier Transformation (FFT) to calculate the sum of amplitude and phrase quickly with random numbers of the time. We eliminated the overlap functions of sine and cosines by using the repeatability of trigonometric function. We saved the values of trigonometric function in memory space. Therefore, we could deal with the repetitive calculations by memory access because the same values are repeated in the standard based on π within one cycle of 2π in sine and cosine functions. By changing the sampling size of Windows function, we calculated the mobility on each local area and we applied this mobility to this study according to hierarchical structure. In addition, we used the reflectivity differently by putting the value of k,r into the effect Fresnel reflection. The reason why we used this method was to make the sea look more realistic. In the aspect of the intensity of light of the sea, we did not calculate it and we applied KD- Tree data structure on the density of the values occurred at the time of the sea was created. The advantage of this method was to reduce search time effectively. In this Tree structure, index time  log  , search time and    log  time are spend, which is applied to the photon closed to  . In the case of KD-Tree, this is a very effective way in saving and recovering. One weakness was that we had to limit the effect of indirect illumination to express a wide sea. However, by using photon mapping, we solved this problem

The flow channel is a game design aspect that has been widely used by experienced game designers. A psychologist named Mihaly Csikszentmihalyi found that a person's skill and the difficulty of a task would interact to result in different cognitive and emotional states. When a person’s skill and the difficulty of the task are roughly balanced, he or she enters the flow state. Otherwise, the person becomes bored or frustrated, and switches to another activity[3]. Unfortunately, for game designers, this is the point where the flow theory stops helping. While a designer strive to keep players in the flow channel for as long as possible, he or she has to figure out how to implement the flow channel in the game by oneself. Therefore, in this paper, we tried to bridge or narrow the gap between game flow and psychology theories. We showed how the whole game flow mechanics work and how several major psychological elements operate dynamically and interactively on the game play. The challenges and skills should be balanced and should work together to create game flow experiences. The contents described in the paper was used to teach university students in game design and media psychology courses. Quantitative and qualitative measures show that our media psychology education could be an effective way of teaching a creative design philosophy.

The game of Go is an oriental strategic board game originated from China at least more than 2,500 years ago. The Monte-Carlo Tree Search (MCTS) algorithm in Go is a method that uses a large number of simulations to approximately estimate the winning rate of candidate moves by sampling the game. The two computer Go programs called Crazy Stone and Mogo defeated human Go professionals on the 9⨯9 board in 2006. Prior to our implementing MCTS into computer Go, we tried to find out the best move sequence in playing Tic-Tac-Toe game as a test bed. The experimental results revealed that the first player should play the center to ensure the highest winning rate, and the game result becomes a draw if two players do their best.

In everyday network changing field, permanent service is being an issue. Network disconnection phenomenon is directed to financial damage to service providers. Some companies guarantee on network maintenance, but there is a permitted limit according to their company regulations. If customers overuse the limitation, extra pay will be placed. Moreover, network disconnection affects critical in some fields with using network. Permanent service becomes indispensable in stock, finance, online game, and other fields. Additionally, it should be possible to pre-detect and block abnormal traffic area, improve network infrastructure secureness and optimization, and reduce damage recovery cost. MCS(Multi Connection System) can provide permanent service even if a connection is cut because it provides multi-connection. It can also isolate the attacker when it detects DDoS attack, so it provides smooth service. Also, the benefit from this structure is that the real server can be hidden so the service can be provided continuously. It prevents damages from network cutting, reduces management cost, maintains the best performance, and increases convenient on management and maintenance. Stable and continuous service can be provided with managing network through MCS.

Schizophrenia is one of the most chronic and severe mental disorders. It has hallucinations, delusions, disorganized thinking, a lack of emotion and a lack of motivation. Schizophrenia also causes significant social and work problems. In order to prevent worsening and recurrences of schizophrenia, and to induce continuous improvement of disease, symptom management and medication training are critical factors. A serious game which makes strong interest and immersion senses is a very useful learning tool for schizophrenia patients who show attention deficit, impassiveness, lack of spontaneity and lower motivation. This study uses card match games to improve the patient’s memory and concentration, and encourage procedural learning by associating the difficulty level of the game with the symptom rating scale of disorder. Also it promotes patients to express their feelings through game characters to alleviate their suffering from emotional dullness. It also helps patients to develop teamwork and build interactive skills by demanding cooperative missions for beating the game. Therefore this study is expected to contribute in improving the efficiency of schizophrenic patient education. We suggest to develop serious game design for schizophrenia patients' education.

As the users continuously play the mobile game, the mobile game service requires a method to manage their information such as their game play score and their own game items. For the purpose of responding to the user requests in real time, the proposed method reduces the size of the database by separating the information of inactive users from the main database. Considering the construction cost, the proposed method moves the information of the inactive users to the file instead of another secondary database system. In order to minimize the effect of the system environment such as CPU or memory, the proposed method depends on the response time to the user request rather than the last login time or the number of the user accounts. For the safety and consistency of the database, the proposed method utilizes a traditional RDBMS rather than NoSQL.

In this paper, I tried to study the legislative history on the controversial issues in relation to the "web-board" game. The legislative procedural issues and the controversial regulations needs to be investigated in sequential analysis and review with the view of content validity and formal legitimacy. The second annexed list of the enforcement decree of the GAME INDUSTRY PROMOTION ACT is based on the article 28 (Matters to be Observed by Game Products related Business Operators) and its main fround is the item 8 "He/she shall observe matters prescribed by Presidential Decree as other matters necessary for maintaining business order." These provisions have many legal problems with the "Rule of Law" principle ("Vorbehalt des Gesetzes" in german), Overbreadth doctrine, Void for vagueness and the The Less Restrictive Alternative(LRA) doctrine etc. The regulation on the "web-board" game industry seems to be very severe and rigorous, because the balancing between the public interest and private one is not considered and corresponded well. It caused many harmful effects on the game industry, game business operator and its users. However, the purpose of legislation might not be achieved due to the weakness of the regulation so that the policy failure may bring about the loss of trust in the governmental regulation. The regulation on the game industry and ICT system needs to be authenticated as a measure to promote the business and rationalized to protect the game users.

This article dealt with some legal issues mainly related to a Real Money Trading (RMT) in web-board games in Korea. For clarifying in detail, this paper showed lots of real case found in U.S. and China. These case studies was to reach a common principle, that is, “RMT is everywhere in the real world.” And then, this article tried to examine and evaluate whether a RMT in web-board games has an intrinsic characteristic of gambling in terms of the legal questions. In this part, this study leads to the conclusion that a RMT in web-board games does not meet the legal concept of “Chance” and “Prize.” Furthermore, it is not reasonable that providers of web-board games take legal responsibility for not only a RMT that is not controlled and caused by them but also quasi-gambling experience by the RMT. This analysis is supported by some cases ruled by Supreme Court in Korea. Nevertheless, a RMT in real world is still considered as illegality of providers of web-board games by the Korean government. And more, in recent, the government gets to apply more strict regulation to most kinds of game. This is not common and proper regulatory system in national service areas as well as the WTO and/or FTA systems.

The purpose of this study is to conduct basic research on development of game interface for the elderly by verifying the difference in user experience based on the type of interface. The methodology of playtest combining experimental research and survey was applied with subjects of elderly users consisting of 47 men and 48 women being ages 60 and up. The effects of user experience between natural user interface and the pad-type interface were compared and analyzed through repeated measure MANOVA in terms of emotional response, ease of use and flow. The NUI game showed higher emotional responses such as pleasure and dominance. On the other hand, there was no difference in arousal. The NUI game also presented higher ease of use in the process of game play and it also had higher autotelic experience, action-awareness merging, sense of control and ambiguous feedback experience. These results may contribute to the development of serious game and natural user interface for the elderly by empirically identifying the effects of user experience on NUI.

This study employed the eye-tracking method to investigate the nature of game players' visual attention on the game's GUI(graphic user interface) elements during game play. The genre of the game (shooting and driving games), the points of view of the game (1st person vs. 3rd person POV), and the game player's proficiency were taken into account to examine their effects on the game player's visual attention. A within-between subject experimental study was conducted (N=26). The results illustrate that the game genre was not a meaningful predictor for neither the frequency or the total duration of visual element per interface element. The point of view had a significant main effect on the game player's frequent change of their eye movement across different elements. The proficiency of game player's gaming skill significantly altered the game player's frequency and duration of visual attention. Proficient gamers were more efficient in distributing their visual attention across various elements of the GUI.
