We designed a family of completely autonomous mobile robots with local intelligence. Each robot has a number of on-board sensors, including vision, and does not rely on global positioning systems The on-board embedded controller is sufficient to analyze several low-resolution color images per second. This enables our robots to perform several complex tasks such as navigation, map generation, or providing intelligent group behavior. Not being limited to playing the game of soccer and being completely autonomous, we are also looking at a number of other interesting scenarios. The robots can communicate with each other, e.g. for exchanging positions, information about objects or just the local states they are currently in (e.g. sharing their current objectives with other robots in the group). We are particularly interested in the differences between a behavior-based approach versus a traditional control algorithm at this still very low level of action.

Poker is a game of imperfect information where competing players must deal with multiple risk factors stemming from unknown information while making the best decision to win, and this makes it an interesting test-bed for artificial intelligence research. This paper introduces a new learning AI algorithm with embedded opponent modeling that can be used for these types of situations and we use this AI and apply it to a poker program. The new AI will be based on several graphs with each of its nodes representing inputs, and the algorithm will learn the optimal decision to make by updating the weight of the edges connecting these nodes and returning a probability for each action the graphs represent.

Inter-Organizational Cooperation is the most common and important strategy in modern public and privet sectors managerial activities. In this paper the concepts of inter-organizational cooperation means not selfish cooperation as in the game circumstance and theory, but general collaborative action between organizations, they have share same goal. The achievement level of jointed-goal of inter-organization is depended upon the performance of cooperation, which resulted from the conditions and circumstances of cooperation. This paper analyses the effect of inter-organizational cooperation on achievement level of the jointed goal between two organizations with computer simulation model of the system dynamics approach. In the computer simulation model, three factors, goal perception, communication, and control, are considered as a key conditions of cooperation, which impact on the performance of cooperation. Simulation model was constructed with focus on the dynamic interactions between these three factors and the achievement level of jointed-goal. Consequently, the results found in this paper may provide further grounds for reducing the time delay that included in the conditions of cooperation.

요즘 사람들이 많이 즐기는 전략 게임은 전략 시뮬레이션이라는 말이 무색할 정도로 장르가 가지는 특성 을 이행하지 못하고 있다. 그래서 게이머들은 별다른 전략 없이 쉽게 컴퓨터를 상대로 쉽게 게임을 승리 할 수 있게 됐다. 이것은 게임의 재미를 크게 반감시키는 한 요인이 된다. 전략 게임의 컴퓨터 플레이어에게 상황 판단과 학습 능력을 갖게 하면, 게이머가 보다 재미있게 컴퓨터와 대전을 할 수 있다. 본 논문에서는 인공지능을 가지는 컴퓨터 플레이어에 사용될 Default 추론 엔진과 컴퓨터 플레이어의 작전과 행동을 결정하기 위한 action & strategy generator 시스템을 연구한다. Default 추론 엔진은 귀납적 학습방법을 통 해서 컴퓨터 플레이어가 추론 및 학습을 할 수 있는 정보를 생성하게 된다. 이렇게 생성된 정보를 바탕으로 컴퓨터 캐릭터의 행동과 전략을 결정한다. 이에 본 논문에서는 전략 게임에 인공 지능으로 machine leaning 기법 중의 하나인 decision Tree 틀 사용하였다. decision Tree를 적용하여 기존 컴퓨터 플레이어의 행위와 어떻게 다른지 차별성을 밝혀내고, 컴퓨터 플레이어가 향상된 전략을 구사할 수 있게 하는 것이 주된 목표다.

본 논문에서는 1인칭 시점 VR 게임 콘텐츠를 개발하였고, 멀티플레이를 구현할 때, 가상현실 세계에서 플레이어들끼리 대면했을 때 서로의 캐릭터가 폰 콘트롤러라는 이름의 팔만 보이는 외형을 띠고 있다. 게임에서 시각적인 부분을 간과할 수 없기에 멀티플레이 시 서로의 캐릭터가 보일 수 있도록 새로운 방법을 제안하였다. 3인칭 캐릭터를 이용해서 만든 캐릭터는 인간과 같은 외형의 스켈레톤을 사용하면 원하는 캐릭터를 사용할 수 있다. 3인칭 캐릭터의 양팔의 트랜스폼 값을 언리얼엔진4의 라이브러리인 패브릭 노드를 이용하여 모션 콘트롤러와 매핑을 시키는 방식으로 접근하였다. 이를 통해 좀더 플레이시 실감이 가능한 게임 제어기법을 적용할 수 있다.

Educational objectives are the most important items because not only they must be decided first in the circulation process of curriculum but also they should be the basis for the process of curriculum. The establishment of objectives is very important because it can determine success or failure of computer education. In this paper, questionnaire research is conducted and analyzed for male students of middle schools in Chungbuk province, Korea to determine that it's reasonable for computer games to be perceived negatively. The results of the research are as follows. 48% of them are represented to play computer game almost everyday, and 8% to play it scarcely. So most of students are enjoying it regardless of their grade. If students whose grades are ranked upper level start playing games, they're tend to quit it within 1 or 2 hours. And they enjoy role-playing or simulation game. In general, they do not play action games. If their grades are ranked lower level start playing games, a lot of them continue to play longer than 3 hours like game addict. And in this level, there exist students who barely play games. In middle level, there are no apparent characteristics. According to the result of the research, there is no correlation between frequency of playing games and academic achievements. So it's no problem to relieve worries if one often play computer games, his or her grade will get down. In case that the grades of students are ranked upper level, however, there are few who continue to play games longer than 3 hours.

When was launched in 2014, it was immediately ranked 2nd in English gross sales record in the first half of 2014, attracting huge attention from avid game users. Colin Moriarty(2014) states that the worldwide popular game, , lies on the alternative history assumption, 'what if Nazi Germany won the second world war? In regard to this, this research addresses how the characteristics of alternative history was adopted and visually represented in FPS game trailer. In terms of research method, firstly, literatures will be reviewed about definition of alternative history and some of the previous examples where alternative history was applied in novels, films and games. Secondly, narrative composition of alternative history is categorized as three sequential phases, (1) borrowing real history material, (2) connection between real and fictional history and (3) reconstruction of history through reinterpretation. Thirdly, the live-action game trailer will be analysed by three sequential phases of narrative composition, and CG game character and background will be analysed by spatial background, characters and props. The phase of 'borrowing' has used the historic images related to the World War II, and the phase of "connection' has composited by "connection through circumstantial events". The phase of 'reconstruction' has unfolded its fictional narrative in the form of "limited fictional history" In addition to this, has constructed dystopia world through composing of historic images and CG characters by SF design. In the light of this, the narrative composition of alternative history successfully extends to game area.

Recently the telemedicine platform firms which have been temporarily permitted since COVID-19 outbreak have increasingly provided online prescription drugs delivery, causing concerns among incumbent providers of medicine, some of whom began to take aggressive actions again them. In this study, using game theoretic market entry - deterrence model, we show that although the incumbent medicine provider can effectively deter entry by the telemedicine platform firms by its preemptive action, accommodation could be a optimal action when telemedicine platform firms already have penetrated the market with their being permitted to do business due to the COVID-19. However, for the incumbent to cooperate for the successful change in the retail market for medicines, policies like placing a ceiling on the maximum number of taking prescriptions by the pharmacists a day in the telemedince platform network, providing favorable exposure of community pharmacists on the telemedicine platform user interface, and allowing community pharmacies to participate as shareholders of the telemedicine platform firms in its initial public opening of capital, are suggested.
