This study has focused to identify what kinds of psychological state are most closely related in players experiencing flow while playing game. This study constructs a conceptual model of flow for game players by conducting a survey to 303 online game players. The results indicate that the state of flow was reached when players may gain opportunities for having high self-efficacy as they accomplished tasks. At the same time, it indicate that the higher cognitive performance and self-esteem was able to enhance the higher flow experience while playing a game. This study provides both practical and theoretical implications on how to increase players' flow by providing critical psychological states in the game.

Serious games are selected by users according to the original goals such as education, treatment, training and so on. Therefore, those type of games are evaluated inside and outside the game about whether the goals are archived or not. Among quality test elements of serious game, assessment is about whether, in games, ability to verify goal achievement is included or not. In this paper, we examined the achievement-assessing function of serious game through several cases. Furthermore, to utilize for developing serious games for English learning, we designed a level system which achievement-assessing function is applied to. In this level system, we used 'competition and reward' as the core elements of game, and designed the system through simulation of which grades are level-designed along the user's English proficiency level based on notice of MEST(Ministry of Education, Science and Technology). This paper is expected to be useful reference for designing English learning game containing achievement assessing function.

The artificial intelligence (AI) of Non-Player Companions (NPC), especially opponents, is a key element to adjust the level of games in game design. Smart opponents can make games more challenging as well as allow players for diverse experiences, even in the same game environment. Since game users interact with more than one opponent in most of today's games, collaboration control of opponent characters becomes more important than ever before. In this paper, we introduce a cooperative strategy based on the A* algorithm for enemies' AI in the Pac-Man game. A survey from 17 human testers shows that the levels with our collaborative opponents are more difficult but interesting than those with either the original Pac-Man's personalities or the non-cooperative greedy opponents.

최근 게임 산업에서는 게임을 인공지능적인 측면으로 접근하는 방식 중 하나로 인공감정을 주목하고 있다. 인공감정은 감정자극과 감정, 그리고 감정의 표현 방식이라는 총 3가지 기본요소로 이루어져 있다. 본 연구에서는 인공감정을 사람들에게 꾸준하게 인지도가 상승하고 있는 캐주얼 게임에 적용시켜 보았다. 캐주얼 게임은 다른 게임들에 비해 게임 속에서 감정을 느낄 수 있는 환경요소가 한정적이고, 표현할 수 있는 감정이 적어 인공감정에 대한 플레이어의 반응을 실험하기에 적합한 게임 장르이다. 본 연구에서는 쉽게 제작 가능한 버튼 클릭 방식의 캐주얼 게임을 만들었다. 그리고 게임에 플레이어의 행동을 통해 감정적 영향을 받는 인공감정이 적용된 게임 에이전트를 제작했다.

컴퓨터 게임 산업이 발전함에 따라 사용자의 흥미를 측정하거나 불법 소프트웨어 구별을 위해 사용자 분석에 관한 연구가 진행 중이다. 그 예로 최근에 사용자 분석을 통하여 게임 레벨 디자인을 하거나 이를 게임 균형에 이용하는 연구들이 있다. 본 논문은 개인적인 게임 환경에서 사용자의 적절한 게임 경험을 위해 시간열 데이터 마이닝 개념을 이용하여 게임 사용자 모델 분석을 제안한다. 본 논문은 사용자가 게임을 하고 있는 동안 의미 있는 사용자 행동을 저장하고 차원감소와 SOM을 이용하여 4가지 행동 유형으로 클러스터링하고 행동 유형에 따른 사용자를 분석한다.

In this paper we tried to figure out the types of real money trade of game items, and in order to study it we examined the Leveling System of MMORPG which is a perfect competitive market and how the closed structure of the game economy emits real money trade. The over production of the MMORPG's leveling system which is a perfect competitive market increases the amount of currency in circulation and then induces arbitrage due to mudfalation inside the game. In order to improve this problem, there are three methods of resolutions. The first is stabling the game economy by spontaneous order among the game users, but this is much local than the artificial order which takes a long time and evokes discrepance in MMORPG competitive characteristic. Secondly, legislational regulations from the government could improve the problem, but this method doesn't grant information or services as non-material labor in which it couldn't follow up the developing speed of the game market. Finally, delicate modulation among game items by the designer isn't possible to constrain them, and there is a limited reason that it couldn't control the increase of currency which is the main factor of arbitrage.

본 논문에서는 Unity 3D 엔진을 이용하여 게임개발을 위한 학습용 앱의 구현 내용을 소개하였다. Unity 엔진을 이용하면 필드의 제작, 캐릭터 애니메이션 세팅, 스크립트 작성, Asset 관리, 레벨 디자인 등 많은 작업을 하나의 통합 환경에서 수행할 수 있다. 또한 컴파일 과정을 거치지 않아도 게임을 제작하는 도중 언제라도 실행해 볼 수 있기 때문에 개발에 걸리는 시간을 단축할 수 있다. 본 연구의 과정은 게임 앱 설계 관련 프로젝트의 수행이나 학습용 게임 개발의 학습 모형을 제시한 사례로 활용할 수 있다.

The Management of Game Money in online game is considered as a crucial factor for successful game business as well as balancing game economy. The generation and flow of game money have a strong relationship with game contents, entertainment factors, game planning and level design. This paper explores online game economy in various ways especially the matter about managing & controlling game money in this context through theoretical and practical perspectives. It also examines how this management makes an effect on 'Free to Pay' policy and Sales revenue. Finally, this paper draws conclusions about the Management of Game Money which can be considered to be practically useful for game development and management. I hope that the study helps further studies and researches and can be served as a foundation regarding the issue.

This paper analyzed maximized the tension not by functional restriction but by psychological response inducement to form the tension of the horror game from the point of space time view. In order that, We arranged three major situations inducing the tension in the horror game and prepared space time analysis base. Pure fiction time of game itself is applied on game time excluding the time creating the cut-scene and the game space is organized with various combination of three space types. This analysis result can help horror game design by discovering the relationship between space time structure and tension forming of the horror game. These analysis results allow us to find guidelines for the time and space design of horror games that can be flexibly linked to game events and contexts by controlling the player's dynamic/static tension and temporary/continuous tension.

This paper will study the influence of comedic elements of the game on the gaming choice by the game users, and focus its goal on establishing the foundation for the various game production environments. Within the game, the comedic elements are categorized as one of actively expressive elements and enhance the game's entertainment together with its sound qualities of graphics, scenario, sounds and level designs. Although the comedic elements are generally acknowledged as necessities, the research on how the users actually perceive those elements has been insufficient. Therefore this paper will investigate characteristics, compositions and techniques of the comedy used in the game and will analyze the influence that those comedic elements have on the users' recognition, satisfaction and royalty to the game.
