It is an interesting area in the field of artificial intelligence to and an analytic model of cooperative structure for multi-agent system accomplishing a given task. Usually it is difficult to design controllers for multi-agent systems without a comprehensive knowledge about the system. One of the way to overcome this limitation is to implement an evolutionary approach to design the controllers. This paper introduces the use of a genetic algorithm to discover a fuzzy logic controller with rules that govern emergent co-operative behavior: A modified genetic algorithm was applied to automating the discovery of a fuzzy logic controller jot multi-agents playing a pursuit game. Simulation results indicate that, given the complexity of the problem, an evolutionary approach to and the fuzzy logic controller seems to be promising.

This study is aiming to find one of working conditions for loading and unloading a large ship at game port. Firstly, for dynamic analysis of the moored ships, the motion characteristics of ship according to loading condition are figured out. The motion characteristics of ship is related to environmental factors such as current, wind, mooring line, fender and etc. As a result, it is ascertained through numerical simulation using the AQUA MARINE developed by ANSYS INC. This study might contribute to make a new method of mooring stability of target ship.

This paper presents a cooperative action controller of a multi-agent system. To achieve an object, i.e. win a game, it is necessary that a robot has its own roles, actions and work with each other. The presented incorporated action controller consists of the role selection, action selection and execution layer. In the first layer, a fuzzy logic controller is used. Each robot selects its own action and makes its own path trajectory in the second layer. In the third layer, each robot performs their own action based on the velocity information which is sent from main computer. Finally, simulation shows that each robot selects proper roles and incorporates actions by the proposed controller.

This paper proposes a method for determining navigation path of an autonomous mobile robot in surrounding environment using a fuzzy algorithm. This fuzzy algorithm includes three type (MIN-TIME, ECONOMY, SAFETY) motion mode for the given robot to get the ability to meet the ambiguous situation which the robot will encounter. Each node is applied to the game situation. This paper conclude with some results of computer simulation concerning an evaluation of this method.

In the paper, we propose an energy efficient sensor network management scheme. In the proposed scheme, the modified game theory and ${\varepsilon}$-constraint techniques are sophisticatedly combined to establish energy efficient routing paths. Simulation results indicate that the proposed scheme can strike an appropriate performance balance between conflicting requirements while other existing schemes cannot offer such an attractive performance.

최근 스마트폰의 발달과 높은 보급률로 인해 모바일 어플리케이션 시장이 급속하게 확대되고 있으며, 게임 시장 역시 스마트폰의 발달 흐름에 맞추어 조작이 간단하고 쉽게 즐길 수 있는 게임이 많이 개발 되고 있다. 본 논문은 이러한 흐름에 맞추어 사용자들이 쉽게 즐길 수 있는 육성 시뮬레이션 게임을 설계 및 구현하였다. 본 논문에서 구현한 게임은 기존의 육생 시뮬레이션 게임과 달리 가위바위보를 통하여 게임을 진행하도록 구현하였다. 또한 게임의 재미를 높이기 위해 컴퓨터가 랜덤으로 패를 선택하는 것이 아니라 사용자의 패를 예측하고 계산해 패를 낼 수 있도록 가위바위보 알고리즘을 2개의 패턴으로 개발하여 적용하였다.

In past patriarchal societies, childbearing was considered the sole possession of women. At a time when women were struggling to move into society, the concept of parenting as the mainstay of the capitalist economic society and the head of the family has naturally been taken for granted by a woman named "housewife." Since the role of male babies is as important as that of females, Fathers are trying to promote the importance of the effects of fathers due to active participation in childcare and help change old perceptions of the past. Men also know the importance of participating in childcare in early childhood, but often do not know what their children want or why they cry due to lack of basic child care knowledge and lack of education. We tried to give fathers the meaning of indirect experience and change their perception of parenting by producing interactive VR content, which is completed with dad's participation, so that they can experience the child in person. In addition, through familiar childcare professional product advertisement and 360 degree stereo sound. It is made to immerse in the game to gain persuasive effect, inducing fathers to have interest and interest in childrearing.

From a cognitive perspective, this study investigates the role of emergent leaders in developing team cognition and affecting team performance. With application of the cognitive complexity theory, this study hypothesizes that emergent leaders' cognitive complexity will be positively associated with team cognitive complexity, and that team cognitive complexity will be positively associated with team performance. In addition, team cognitive complexity is hypothesized to mediate the effect of the cognitive complexity of emergent leaders on team performance. To test the research hypotheses, data were obtained from 100 teams comprising a total of 339 undergraduate students who participated in a business simulation game. The findings of this study suggests that the cognitive complexity of emergent leaders is a significant predictor of team cognitive complexity, and that team cognitive complexity is positively related to team performance. Moreover, team cognitive complexity significantly mediates the effect of emergent leaders' cognitive complexity and team performance.

캡스톤 기업 연계형의 과제로 드론 교육에 쓰이는 시뮬레이션을 대체할 드론 교육 게임을 제작한다. 교육생의 입장에서 시뮬레이션은 복잡하고 지루하기 때문에 다양한 교육과 정보, 재미있는 콘텐츠를 담은 드론 게임을 만들어 스스로 학습을 진행하게 하는 것이 목표이다. 제작에 앞서 먼저 연구된 시뮬레이션과 게임을 통해 어떤 문제로 상용화가 되기 힘이 들었는지 조사했다. 재미있는 콘텐츠를 제공해 드론 기초 조작을 쉽게 학습할 수 있도록 유도했지만 교육생들이 실제 드론을 어떤 컨트롤러로 조작하는가에 대한 조사가 미흡했다. 이를 해결하기 위해서 필요한 학습 콘텐츠를 설계하고 교육생들이 소지한 드론 컨트롤러로 체험을 할 수 있도록 구현했다.
