Mighty is an imperfect information game, similar to the internationally popular four-player card game Bridge, but more complex in terms of game rules and operation. An environment for exploring and analyzing the strategy of the Mighty Game is required, but compared to the development of many simulators for strategy analysis of other card games such as Bridge, there is no analysis tool for the Mighty Game. Even the definition and understanding of the Mighty game at the academic level is lacking. To solve these problems, this paper systematically defined the procedures and rules of the Mighty Game. And based on this definition, we implemented a simulator that can learn Mighty game and analyze various strategies. For the usability and accessibility of the service, the simulator was developed with JavaScript, and various analysis functions are provided in the web environment. Lastly, comparative analysis with other trick-taking games dealt with in the related research domain showed that the Mighty game has its value as an incomplete information game and that there are many characteristics that make it easy to apply AI-based learning methods.

This paper describes the development of a brickwork game with three-dimensional computer graphics as one of web-based game contents. Client user using web can access and run lava applet program with the independence of hardware system. It consists of graphic user interface module, initial space generation module, event handler module, player control module, and thread control module. It uses 3-D array data structure for the 3-D graphic objects that are located in three-dimensional space for high-speed object searching and sorting. It enhances to compare with predetermined construction in three-dimensional space. We can use the developed racing game to inform game users of information for an advertisement like tourism information, and can apply the proposed 3-D drawing technology to 3-D game graphic engine core.

These days computer graphics technology has been applied in diverse IT fields. Needs for computer graphics such as 3D Printer, Head Mount Display, VR & AR are growing rapidly. Computer graphics will be more specialized and demanding for graphics specialists will be also increased. However, serious mathematical background obstructs people to learning computer graphics. An efficient computer graphics learning system would be helpful for graphics experts training. By analyzing the graphics theory, we propose an educational software system with that students can effectively learn computer graphics. Our system focuses on theoretical objects of computer graphics and enhances accessibility and intuition using web and blocks.

This paper deals with an information security problem that involves the strategies of both an attacker and an administrator of a web-based system. A game-theoretic model for the problem, based on an Stackelberg game environment, is presented. In the model, the administrator selects a set of anti-virus vaccines to cope with potential system attackers and the intruder chooses attacking modes that are most effective against the administrator's chosen set of vaccines. Moreover, the model considers a number of practical constraints, such as a budget limit on the vaccine purchase and a limit on the system performance. In addition, two different scenario analyses are provided, based on the results of the proposed model applied to a simulated pseudo-real-world data.

Most online games today are provided via a website interface. Researchers found that various aspects of a game website importantly influence the success of the online game business. This paper aims at identifying key site-related quality factors affecting the success of online casual game websites and creating a model for measuring such success. To meet this end, we extracted basic factors from the literature and expanded them through a Delphi survey method in which domain experts were asked to identify key quality factors of online game websites. Then we performed a questionnaire survey using online game users for an empirical analysis. The results revealed that information quality, service quality, and system quality are all positively related to user satisfaction and that an increase in user satisfaction leads to an improvement in both gamer loyalty and business outcomes. However, it was found that gamers' loyalty does not necessarily increase business outcomes. The paper offers practical as well as academic implications based on the research findings.

본 논문에서는 캐릭터 챗봇을 학습시키고, 학습된 모델을 React 기반 웹 페이지에 통합하는 것을 목표로 한다. 웹 페이지 사용자들은 실시간으로 게임이나 영화 캐릭터와 대화할 수 있는 기능을 제공받게 된다. 캐릭터 챗봇은 사용자의 질문을 이해하고 학습된 캐릭터의 특성에 따라 적절한 응답을 생성함으로써 상호작용하게 된다. 사용자가 웹 페이지에서 입력한 질문이나 요청은 챗봇 모델을 통해 처리되며, AI 챗봇은 학습된 지식과 데이터를 활용하여 응답을 생성한다. 사용자는 웹 페이지에서 자연스러운 대화를 통해 원하는 캐릭터와 대화를 이어갈 수 있게 된다.

The established Web Based Learning System had not encouraged Multi-Learner Interaction. The System for Multi-Learner Interaction proposed an alternative measure. By now, this System for Multi-Learner Interaction have applied the sphere of Web Based Learning. But, Actually, the Multi-Learner's Interaction and Feedback of this System has a few effective and confidence, because this System has much time gap between Interaction and Feedback of Multi-Learner primarily. This Research propose an answer of this Problem, Web Based Real Time Quiz-game Type Learning System for Multi-Learner Interaction. Moreover, this System expect increased concentration ability for Learning and strong motivation of Learning for the greatest Learning effects in a Subject Solution course of Learners with founding Web Based Quiz-game Type Learning. So this Research will design and implement the Web Based Real Time Quiz-game Type Learning System for Multi-Learner Interaction.

컴퓨터 게임은 정보화의 진전, IT기술의 발전과 더불어 그 파급 속도와 사회적 영향력이 가중되고 있으며, 그 특성으로 인한 프라이버시 침해, 해킹 등 정보화의 역기능이 심각해지고 있다. 이 같은 다양한 정보화의 역기능은 u-society에 대한 새로운 도전으로 작용하고 있어 새로운 위협이 상존하는 유비쿼터스 환경 하에서 안심하고 u-IT 혜택을 누릴 수 있도록 하기 위해 보다 심층적인 정보보호 정책마련이 필요하다. 본 연구는 전문가들의 의견을 수렴하여 정보보호 정책이 정보지수에 미치는 영향을 분석, 도출된 결과를 바탕으로 기업이나 국가에서 정보보호 관련 정책 수립 시 적용할 수 있게 함으로써 국내 정보보호에 대한 수준을 보다 향상시키고자 한다.
