이 세상에 완전히 새로운 창작물이 있을까? 현존하는 대부분의 창작물은 그 이전의 창작물을 학습하고 분석해서 그 토대 위에 보다 발전적으로 또는 개성 있게 표현한 것들이다. 지난 호에서 설명한 바와 같이, 저작권법은 특허법과 달리 창작성이 있는 표현(expression)을 보호하고 아이디어(idea) 자체는 보호하지 않는다. 그 이유로서, Idea는 창작이라는 빌딩을 지을 때 가장 기초가 되는 벽돌(building blocks)의 역할을 하는 것으로 그 도구를 특정인의 독점하에 두지 않고 만인(public)이 자유롭게 이용함으로써 문화, 예술 및 과학의 발전을 도모할 수 있기 때문이다. 영화나 음악과 같은 문학저작물과 달리 소프트웨어나 게임은 기능성이 강한 저작물로서, 개발자가 소스코드(source code)를 공개하지 않으면 그것의 구조나 운용원리 및 아이디어를 쉽게 이해할 수 없다. 이러한 비공개 소프트웨어의 기능적 구성요소를 이해하기 위해 산업계에서는 역분석(reverse engineering)이란 공정을 활용해 오고 있다. 그런데 아이디어를 얻기 위해 수행된 프로그램역분석 과정은 필연적으로 원프로그램(original program)의 복제를 수반 하게 되므로 그것의 저작권 침해여부가 미국과 유럽 등을 중심으로 뜨겁게 논의돼 왔다. 이에 SW 역분석이 무엇인지 그리고 역분석 을 하면 타인의 저작권을 침해하게 되는 것인지 여부를 소니 플레이스테이션 사건을 중심으로 검토해 봤다. 또한 역분석은 영업비밀을 밝혀내는데 중요한 수단으로서도 사용될 수 있는데, 그것의 법률관계도 함께 살펴봤다.

This paper studied cooperation and reciprocity mechanism by analyzing game mechanics of MMORPG 'World of Warcraft: Classic'. MMORPG is the genre of game where social interaction vigorously occurs. This study figured out the structure of cooperation based on evolutionary psychology, anthropology and social psychology through participatory observation. Four cooperation and reciprocity mechanism were drawn through investigating game mechanics like instance dungeon, clear role setting, item, soulbind. In addition, this paper suggests providing ideas of making cooperation mechanism in the field of game design.

This paper uses counterexamples for solving reachability games. An objective. of the game we consider here is to find out a minimal path from an initial state to the goal state. We represent initial states and game rules as finite state model and the goal state as temporal logic formula. Then, model checking is used to determine whether the model satisfies the formula. In case the model does not satisfy the formula, model checking generates a counterexample that shows how to reach the goal state from an initial state. In this way, we solve many of small-sized Push Push games. However, we cannot handle larger-sized games due to the state explosion problem. To mitigate the problem, abstraction is used to reduce the state space to be che cked. As a result, unsolved games are solved with the abstraction technique we propose inthis paper.

This paper presents an interactive educational game design procedure using the DGBL (Digital Game-based Learning) methodology that will help developers to design a multipurpose educational game. The DGBL consists of five stages, which are Analysis, Design, Development, Quality Assurance, and Implementation & Evaluation. This paper is focusing only on the specific technologies included in the Analysis and Design stages based on the DGBL. The first Analysis stage consists of gathering requirements, determining game ideation and learning objectives, and the second Design stage consists of defining the game architecture and database scheme. In this paper, we have designed a lecturers introduction game for a new student or freshmen as a case study to apply the Analysis and Design stages based on DGBL, as well as showing the prototype result in the form of a storyboard.

The quality of the game can be evaluated by its fun and functional stability. Among them, the quality area for fun is the essence of the game, so it is a very important factor to be considered from the point of view of a game designer. Usually, fun games with high originality and immersion are designed in the early stages of development, such as idea generation and concept setting. At this time, making it possible to verify the fun factor of the game has an important influence on the success of the game. In this study, the case of using PIT technique when teaching fun element design to students who are starting to study game design was introduced and the effect was analyzed. It is expected that the PIT technique will be used more actively in the game design education field for high-quality and fun game design.

The Game development process that the Korea Game Development Infinity researches and publishes has laid important groundwork for the game industry. However, the game design cannot guarantee a software quality because an artifact is made incorrect by a game planner's new idea and modification. In this paper theorized the system to maintain artifacts consistently that is generated in planning phase and make changed contents traceable. First, it defined an ACT graph to represent relation of between artifacts, a ACT table that traces and manages it changes and a table of artifacts change history. Also, it suggested the ACT process applying as we mentioned above. Then we worked a case study to verify the change tracking technique which is presented. In a case study, we find game designer is capable to grip and modify a change of artifacts when it occurs a change of game design artifacts. As a result of that, we can save the time and effort to maintain the consistency among game design artifacts.

This paper studies the GUI design of motion-sensing game character selection. The game's GUI plays a role in transferring information in human-computer interaction. The purpose of this game player-oriented GUI design is to optimize the human-computer interaction, make the operation more user-friendly, reduce the user's cognitive burden, and better adapt to the user's operation needs. This paper combines examples to compare and analyze these three games from three aspects: text, color and form. In the existing motion-sensing game games, the character selection GUI has a design feature of high recognition and strong visibility. Finally, suggestions for GUI design of motion-sensing game games are given. It is hoped that in the future, reference materials will be provided for the GUI design of experience game character selection.

본 논문에서는 ‘다목적 함수 최적화 문제(Multi-objective Optimization Problem MOP)’를 풀기 위하여 유전자 알고리즘을 진화적 게임 이론 적용시킨 ‘내쉬 유전자 알고리즘(Nash GA)’과 본 논문에서 새로이 제안하는 공진화 알고리즘의 구조를 설명하고 이 두 알고리즘의 결과를 시뮬레이션을 통하여 비교 검토함으로써 ‘진화적 게임 이론(Evolutionary Game Theory : EGT)’의 두 가지 아이디어 -‘내쉬의 균형(Equilibrium)’과 ‘진화적 안정전략(Evolutionary Stable Strategy . ESS)’-에 기반한 최적화 알고리즘들이 다목적 함수 문제의 최적해를 탐색할 수 있음을 확인한다.
