  • 멀티 에이전트 강화학습에서 중요한 이슈 중의 하나는 자신의 성능에 영향을 미칠 수 있는 다른 에이전트들이 존재하는 동적 환경에서 어떻게 최적의 행동 정책을 학습하느냐 하는 것이다. 멀티 에이전트 강화 학습을 위한 기존 연구들은 대부분 단일 에이전트 강화 학습기법들을 큰 변화 없이 그대로 적용하거나 비록 다른 에이전트에 관한 별도의 모델을 이용하더라도 현실적이지 못한 가정들을 요구한다. 본 논문에서는 상대 에이전트에 대한RBFN기반의 행동 정책 모델을 소개한 뒤, 이것을 이용한 강화 학습 방법을 설명한다. 본 논문에서는 제안하는 멀티 에이전트 강화학습 방법은 기존의 멀티 에이전트 강화 학습 연구들과는 달리 상대 에이전트의 Q 평가 함수 모델이 아니라 RBFN 기반의 행동 정책 모델을 학습한다. 또한, 표현력은 풍부하나 학습에 시간과 노력이 많이 요구되는 유한 상태 오토마타나 마코프 체인과 같은 행동 정책 모델들에 비해 비교적 간단한 형태의 행동 정책 모델을 이용함으로써 학습의 효율성을 높였다. 본 논문에서는 대표적이 절대적 멀티 에이전트 환경인 고양이와 쥐 게임을 소개한 뒤, 이 게임을 테스트 베드 삼아 실험들을 전개함으로써 제안하는 RBFN 기반의 정책 모델의 효과를 분석해본다.

  • The present study explored Korean parents' perceptions of and behavior toward game use among teenagers in Korea. A total of 600 Korean mothers of teenagers residing in Seoul and five other metropolitan areas participated in the survey. The survey was constructed based on five categories of variables, including the overall perception of games and game use, specific attitudes toward game use, cognitions about and attitudes toward game addiction, factors predicting parental monitoring of children's game use, and views and opinions about what needs to be done to promote healthy game cultures as well as to prevent problematic game use among teenagers in Korea. Results indicate that the respondents' overall perceptions of and attitudes toward games and game use are negative. In contrast, attitudes toward game use of the respondent's own child are contingent upon various comparison standards. Results also indicate that the respondents tend to overestimate the possibility that their own child is addicted to games, and their perceptions of game addiction are based on a narrow range of behavioral symptoms. Additional analyses indicate that parental monitoring of teenagers' game use can be predicted by the theoretical model driven from Ajzen(1991)'s theory of planned behavior. Finally, results also indicate that, in order to deal with the problems associated with teenagers' game use, proactive approaches to promote healthy game cultures as well as various initiatives to prevent problematic game use are necessary. Implications of the findings and future direction were discussed.

  • 본 연구는 가상 캐릭터인 3D Pooh 와의 감성 교감이 이루어지는 유아용 감성 교육 게임 개발이 목적이다. Web 카메라를 이용하여 사용자의 위치 정보 및 영역을 검출하고 사용자는 화면에 보이는 가상 공간에 손과 마커를 이용하여 행동을 가하게 된다. 사용자의 행동 입력 방식에 따라 Pooh 의 상태를 나타내는 게이지와 행동의 다양한 변화를 제공하며, 이로써 사용자들이 가상 캐릭터인 3D Pooh 와 인터렉션을 할 수 있도록 제공한다. 기존의 감성 교감 연구 방법 분석 결과 뇌파와 체온 등의 생리신호를 이용한 방법과 사용자의 행동패턴을 분석하는 방법 등이 있으며, 현재는 생리신호를 이용하는 방법이 더 많이 활용되고 있다. 생리신호 측정 시 사용자는 신체에 센서를 착용해야 하므로 착용 부담감과 움직임이 자유롭지 못하다는 단점이 있다. 본 프로그램은 기존 연구의 단점인 센서 착용의 부담감을 줄이고 자유롭고 편리한 인터렉션이 가능하도록 개발하였으며, 직관적인 인터페이스를 기반으로 유아들도 쉽고 편리하게 즐길 수 있도록 구현된 감성 교육 게임이 될 것으로 기대된다. 또한 카메라 이외의 다른 하드웨어 장치 사용을 최소화하여 경제성과 사용 편의성을 동시에 고려한 효율적인 유아용 감성 교육 게임으로 활용될 수 있다.

  • This study examined the effects of game genre, news media with differing political ideologies, and game-related information sources on gamer issue participation by performing a hierarchical regression model, using an online survey on Korean gamers (N=1,362). As a result of the study, playing specific genres of games played a positive role in gamer issue participation. The group behavior or collective action for or against game regulation reported in the liberal/moderate media acted as a mobilization cue for readers and potentially encouraged gamers to take social action. But the conservative media, which used governmental organizations and interest groups as sources of information, had a negative impact on real-life participatory behavior. The biased journalism practice of the mass media on game-related social issues influenced gamers' social and political behavior through corrective action. This study is significant in empirically analyzing the relationship between political ideology, game genre, media use, and gamers' social participation. The current research suggests the improvement of game regulation policy and the need for theoretical and conceptual expansion of game research.

  • This study aims to analyze online game user's game items transacting behaviors for the two game genres such as MMORPG and sports game. For the sake of conducting the analysis, we adopted a fuzzy logic agent-based modeling. In the online game fields, game items transactions are crucial to game company's profitability. However, there are lack of previous studies investigating the online game user's game items transacting activities. Since many factors need to be addressed in a complicated way, ABM (agent-based modeling) simulation mechanism is adopted. Besides, a fuzzy logic is also considered due to the fact that a number of uncertainties and ambiguities exist with respect to online game user's complex behaviors in transacting game items. Simulation results from applying the fuzzy logic ABM method revealed that MMORPG game users are motivated to pay expensive price for high-performance game items, while sports game users tend to transact game items within a reasonable price range. We could conclude that the proposed fuzzy logic ABM simulation mechanism proved to be very useful in organizing an effective strategy for online game items management and customers retention.

  • Character identification is illustrated in terms of game players' altered self-perception during gameplay. Research has shown that players' identification with game characters resulted in game players aligning their attitude with game character. This study investigates the relationships among control, ownership, character customization, identification, flow with game charater, and the impact on game players' behavior toward item purchase and play intention. Empirical results showed that character ownership and character customization significantly predicted use-character identification, but the impact of character control was not supported. In addition, the positive relationships between identification and flow was supported.

  • Game artificial intelligence is usually used to provide intelligent and adjusted game environment for user. Previously, it was used for Non-player character(NPC) playing a role of a company or an enemy through collecting and analyzing a user's behaviour. However, it was just mimicking the user's behavior. This paper introduces a method to change game environment by analyzing a user's game behavior. Game behavior data has been used to understand user's game preference. Also, the user's preference was used to provide more active game environment by reflecting decision of geographical features, items and distribution of NPC. For experiment of the suggested method, we utilized a real 2D action game and confirmed the game environment which changing properly according to the user's game play.

  • Based on the research of the Public Welfare Games 'Mountaineering LightsUp', which is the main theme of helping the disadvantaged in society, this study uses the questionnaire method to obtain user data, and collects the data by using AMOS analysis for the effect of game interest elements on the experience of players. The results showed that the interesting elements (goal, obstacles, sense of belonging, atmosphere, story, information, and player to player communication) of the game were positively influenced by the experience of the game. And the questionnaire showed that the game still had problems such as playing simple, difficulty, lack of popularity, lack of feedback, and lack of storytelling. This paper also puts forward some proposals for these deficiencies. In future research, the research sample will be expanded, the research content will be improved, and the future Public Welfare Games will be designed and developed.

  • In this study, we examined the effects of video game play on a variety of areas of mental well-being, such as aggressive behavior, aggressive cognition, prosocial behavior, prosocial attitude, antisocial behavior, antisocial attitude, positive affect, and negative affect. We conducted a multivariate meta-analysis on 22 studies (k= 54, N = 8,031) published between January 2008 and October 2019. The results of the meta-analysis indicate that exposure to violent video games significantly increased aggressive cognition and negative affect only in true experimental studies, but their influences were small. Furthermore, the exposure to violent video games did not increase aggressive behavior and negative affect across all the research designs (true experimental, quasi-experimental, and correlational). Moderator analyses revealed that the effects of exposure to violent video games were much larger for younger adults than for children and greater in male-biased studies than in gender-balanced ones. Additionally, studies using better methodologies were less likely to produce negative effects. These findings suggest that the effects of exposure to violent video games on aggression were not as severe as popular opinion holds, and the effects were heavily modulated by the age and gender ratio of the participants, and methodological quality of the studies.
