급격히 성장해가는 메타버스 시장 속에 메타버스 플랫폼의 증가세와 그에 반해 아직 활성화되지 못한 메타버스의 콘텐츠 크리에이터 생태계로 인하여 다수의 메타버스 플랫폼들의 내부 콘텐츠 확충과 유저 크리에이티브 생태계 활성화의 중요성이 대두되고 있다. 본 논문에서는 보다 체계적이고 효율적으로 메타버스 환경에 맞춘 인터랙티브 콘텐츠 개발 프로세스를 제안한다.

2025년 메타버스에서 주요 응용시장 전망에 의하면, 헬스케어 1,111억 달러, 제품개발 1,097억 달러, 교육 907억 달러, 프로세스 개선 848억 달러, 유통 622억 달러 규모로 성장할 것으로 예상된다. 또한, 2030년 메타버스 시장은 1조 5429억 달러 규모로 더욱 성장할 것으로 예상 된다. 시장이 커져가며 메타버스는 다양한 기관과 전문가들로부터 다양한 속성이 정의되고 있지만, 메타버스를 실질적으로 개발할 수 있는 기능을 제공하는 메타버스 플랫폼(metaverse platform)은 이러한 주요 속성이 얼마나 잘 적용되고 있는지 현 상황을 연구한다. 전 세계적으로 가장 많은 유저를 보유하고 있는 네이버 제페토와 2022년 9월 론칭하며 게임을 통한 메타버스 구현을 목표로 둔 넥슨의 메이플스토리월드에 메타버스의 주요 속성을 대입한다.

As the rise in popularity of online games, the users start exchanging rare items for real money. As RMT (Real Money Trade) is prevalent, GFG (Gold Farming Group) who abuse RMT shows up. GFG causes social problems such as identity theft, privacy leaks. Because they needs many bot characters to gather game items. In addition, GFG induce RMT that makes in-game problems such as a destroying game economy, account hacking. Therefore, It is very important work to collapse GFG at the perspective of social and in-game. In this paper, we proposed a fundamental method for detecting RMT buyers for the collapse of GFG at the perspective of buyer by Law of Demand and Supply. We found two type of RMT by analyzing actual game data and detected RMT buyers with high recall ratio of 98% by ruled-based detection.

Avatars are a visual representation of users in a virtual world such as an MMORPG. These avatars are often seen as representations or idealizations of the user's actual self. However, this view does not account for the prevalence of two behaviors: multiple avatars and 'gender swapping'. An exercise and questionnaire were created to study avatar customization practices across players outside the context of any particular game to understand better user motivations in creating their virtual selves. A preliminary trial of the exercise showed little correlation between age or gender and gender swapping. While those of non-traditional sexuality were more likely to gender swap, half of traditional sexuality also swapped. Finally, the personality trait, Openness to Experience, showed promising correlation with gender swapping.

The avatar gender, the basic element that constitutes the identity of the MMORPG player, can be created by the player due to the nature of the game through the system provided within the game. Thus, players exhibit a different attitude from reality regarding avatar gender. Gender customization in virtual space is an expansion of the identity in an effort to express one's identity in various ways. A number of users manage avatars with the opposite gender where it was found that male players preferred the female avatar persona. In this study, the player attitudes regarding gender was analyzed using Q methodology and the motivational factors for gender swapping and the generalization phenomenon was determined. This study will be significant as critical standards in the usability evaluation of the MMORPG customization system.

In this paper, we formalize a new adaptive online price control scheme based on the Stackelberg game model. By using the hierarchical interaction strategy, control decisions in each mechanism act cooperatively and collaborate with each other to satisfy conflicting performance criteria. In addition, our dynamic online approach is practical for real network implementation. With a simulation study, the proposed scheme can adaptively adjust the network price to approximate an optimized solution under widely diverse network situations.

At th first time in 1985, Tetris appeared, it became game that are loved to many users until now. Existent Tetris employed way to give score according to number of that is destroyed whenever line are destroyed, and give advantage about serial attack and so on, But, these score calculation method gave so fixed and simple pattern. In this paper, We design and implement the new tetris game System by score calculation method per level that Is different with existent method. That Is, this method is to compare present and before with number of destroyed line and give advantage in basis score, Also, It is going to permit strategic utilization of still more developed tetris than existent tetris using score calculation method per level.

If game images use colors improper for certain ages, the characteristics of games disappear, and the efficiency of image expression drops. thus a study in color is very important. Nevertheless, there is a lack of research on this subject. In this study, we investigated the difference of color of game images according to users. User group is divided into all users and users over 18 years old. Among the rank of games,10 each from games for all ages and games for non-teen-rated are selected, and the game-playing images are taken as snapshots to have 100 each images each, A total of 2000 images were extracted and the mean values of RGB and HSB of each game were obtained and independent sample t test was performed. The results showed that the RGB color values between the two users were significantly significant. In the future, it is expected that it will be helpful in color selection when developing psychotherapy games and emotional games using color psychology. Furthermore, we will use color image scales to express colors as adjectives, analyze colors in a variety of ways, and investigate the difference in color of game images in each country.

MMORPG is being progressed through Quest and the level and the balance are realized. Also, Quest plays a strong role of motivation through compensation related with Avatar such as items and experience points rather than a role of story transfer. This situation finally made MMORPG become a difficult game that players should study the compensation of Quest for growth of a character, so it causes fixation of the user class. As a solving method of the fixation of the users, the possibility of Quest capable of strengthening play motive of various users through clarification of motivation structure of the Quest play and pluralistic understanding about players was investigated. The pluralistic understanding method of players will have values as a tool that can design and evaluate Quest satisfying preference of the various user class.

G-learning, based on online game, virtual reality activities and communities, is considered as a fresh, differentiated idea at learning which drives learners' interest and attention. The paper is to analyzed effectiveness of G-learning at the mathematics classes in elementary school. Fourth, fifth and sixth grade students in Seoul are selected as an experimental groups and their achievement scores are measured. The difference between G learning group and textbook group was significant. This result shows that G-learning has a positive effect on learning.
