본 논문은 제어대상체의 지식을 이용하여 적절한 의사결정을 내리거나 또는 지속적으로 변화하는 주변환경에 적응해 나갈 수 있는 지능시스템 설계를 위한 내배엽성 모델링 방법론을 제시한다. 이러한 지능적 내배엽성 시스템은 의사결정 모델, 지식기반의 내부모델, 그리고 내부모델의 구축모델 등을 기반으로 달성될 수 있다. 학습기능의 모델링을 위하여 수정된 귀납추론 방법과 적응형 전문가 시스템 방법이 제안되었다. 제시된 방법론은 지능적 학습 및 의사결정 기능을 갖춘 지능적 카드경기자 모델링의 예를 통하여 그 가능성을 검증하였다. Abstract This paper presents an endomorphic modeling methodology for designing intelligent systems that can determine by itself using its knowledge of the world and adapt itself to continuously changing circumstances. We have developed such an intelligent endomorphic system by integrating the decision making component and knowledge based internal model with internal model construction model. Learning capabilities are established using the modified inductive reasoning and adaptive expert system techniques we developed. Proposed methodology has been successfully applied to a design of intelligent card game players capable of supporting the intelligent learning and decision making.

Most games based on PCs or consoles at present show vivid special effects and brilliance sceneries. However, the other games running on mobiles and portable devices can not show magnificent scenes because of low hardware specifications such as slow CPU, old graphics card and battery capacity. These games relatively prefer light and casual contents that do not need tremendous calculation. It is very important to keep minimum of game graphics quality in those games. Thus this research presents the new possibility of variable indexed color palettes to overcome the low hardware capacities.

This study looked into how to carry out sacrifices for intra-game cooperation in becoming a high-level player. The results are as follows. First, the way players behave is dependent on their resources(scores). Second, the higher the player's score, the more praise cards were given to dealers. Third, high-scoring players have taken on a role of "sacrificing the self to serve the many" by voluntarily playing the role of healer, leading the team to set the rules and consequently reducing the risk of a probable role conflict within the team.

Purpose: This paper aims to investigate the influence of different methods of distributing sweepstakes (i.e., whether consumers choose to enter into the sweepstakes themselves or they are given the sweepstake ticket by default) on the effectiveness of the sweepstakes promotion (i.e., interest in the sweepstakes and intention to participate in the sweepstakes). Research design, data and methodology: The paper verifies this effect through three experimental studies: an online experiment using a sweepstakes promotion scenario at a department store, an online SNS sweepstakes promotion event, and a face-to-face card lottery game. Results: Participants belonging the group that chose sweepstakes tickets by themselves showed higher interest and intention to participate in the sweepstakes than those who were given the sweepstakes ticket by default. Furthermore, the group that chose the sweepstakes card thought it had a higher probability of winning than the group given the sweepstakes card. Conclusions: This paper shows a way to enhance the promotional effect of sweepstakes in the retail stores, without incurring additional costs, by approaching from sweepstakes design from the psychological perspective of the consumer. The study also sheds new light on the effect of sense of control manipulation using choice behavior in the promotional context.

본 논문에서는 Kinect 센서 기반의 카드 매칭 게임을 설계하고 구현한다. 이 게임은 유아용 카드 매칭 게임으로 카드 뒷면을 화면에 배치시키고 무작위로 앞면의 그림을 보여준다. 플레이어는 앞면의 그림을 위치별로 기억하여 같은 짝의 그림을 선택하여 맞춘다. 다른 짝을 매칭 할 경우 다시 뒷면으로 뒤집히고 같은 짝을 매칭 할 경우는 해당 그림의 영어 단어를 팝업시킨다. 예를 들어 토끼 그림의 짝을 매칭 할 경우 RABBIT이란 단어를 팝업 시킨다. 그리고 플레이어는 RABBIT이란 단어를 발음하면 Kinect는 음성을 인식하여 팝업된 창을 종료하고, 게임을 계속 진행한다. 게임은 화면에 배치시키는 카드를 $2{\times}2$부터 시작하여 난이도 별로 증가 시키고 스테이지 별로 콘텐츠를 나눠 영유아들이 재미있게 게임을 즐기면서 영어 단어를 학습할 수 있는 게임이다.

Game agents which are behavioral agent for game playing are a crucial component of game satisfaction. However it takes a lot of time and effort to create game agents for various game levels, environments, and players. In addition, when the game environment changes such as adding contents or updating characters, new game agents need to be developed and the development difficulty gradually increases. And it is important to have a game agent that can be customized for different levels of players. This is because a game agent that can play games of various levels is more useful and can increase the satisfaction of more players than a high-level game agent. In this paper, we propose a method for learning and controlling the level of play of game agents that can be rapidly developed and fine-tuned for various game environments and changes. At this time, reinforcement learning applies a policy-based distributed reinforcement learning method IMPALA for flexible processing and fast learning of various behavioral structures. Once reinforcement learning is complete, we choose actions by sampling based on Softmax-Temperature method. From this result, we show that the game agent's play level decreases as the Temperature value increases. This shows that it is possible to easily control the play level.
