The growth speed of the industry of national smart phone game service has become faster and the its economical and cultural effect has increased steadily these days. The DB design for data perpetuation in C/S MMO which has accumulated data a lot and many simultaneous plays like smart phone games is very important. This paper, mindful of the operation and the scalability suitable for android OS, by utilizing RDBMS, enabling very short, many transactions, their complexity, and a large amount of game data process, suggests fully-qualified MMORPG game DB design techniques widely availabe for more than online game industries.

In the field of defense M&S, we are actively pursuing researches that interoperable multiple war game models to simulate various combat environments at the same time. Although the 'unit DB(Database)' for operating the war game models is originated from the identical data, it has been recognized that the method of expressing the attribute of the data is different and the cross reference is impossible. As a result, it makes unnecessary time and effort in establishing the same unit DB in the organizations that operate the war game model. In this study, a method of reusing the unit DB of the training war game model to the analysis war game model with similar resolution and simulated logic was applied to the actual field. For this purpose, we defined the procedure for converting the unit DB by analyzing metadata of the 'Chang-Jo21', a combat training model for corps and division, and the 'Vision21', an analysis model for corps and division operation plan. And we introduced an algorithm that can map different metadata of two unit DBs. This study was meaningful as the first attempt to map and integrate heterogeneous metadata semantically for the reuse of unit DB between different war game models in defense M&S field. Also, it provided implications for the necessity of paradigm shift that reuse of the unit DB between two different war game models is possible and the need for standardization of the unit DB metadata in the defense M&S filed.

Game scenarios are playing more important role as much as games are getting more sophisticated and expanded in their applications. However, general-purpose tools for production of game scenarios are still not developed. There are similar tools for the production of films or dramas and simple tools for the development of UCG. However, analysis about them shows that they are not suitable for the production of game scenarios. In this paper, we are to develop game scenario authoring tool called 'UMa' suitable for game production and easy to use. UMa is composed of synopsis entry, quest entry, DB entry, communication, display, and control component. Since UMa provides templates to make synopsis, quest, and DB, users can produce them very easily. Especially, characters and items DB are stored independently so that they may be reused to the production of scenarios for follow-up or another game. Using UMa, users can write game scenarios more easily and quickly and cooperate with each other at the same time by Web.

The game has both directionalities that users are to choose and act accordingly. In this regard, the game scenario goes beyond just conveying the story, and trains users and guide them in playing the Same. However, this Same scenario is huge in size and every event is linked with each other so that it was rather difficult to have it made in practice. A study proposes that a script, the minimum unit, is built into a database, and based on which, quests are made, then the resulting quests are built back into a database. Scripts are classified into text, graphic and sound type and these are positioned in accordance with the quest structure. With this method, one can re-use the existing scenarios and can overcome the negatives of irregular qualities of scenarios.

디지털콘텐츠산업은 21세기 국가경쟁력을 좌우하는 10대 차세대 성장 동력의 하나이며, 게임산업은 이와 같은 디지털콘텐츠 산업에 있어 가장 경쟁력 있는 분야로 인식되고 있다. 문화관광부가 발간한‘2004 대한민국 게임백서’의 통계자료에 따르면, 2003년 국내 게임시장은 소비자 매출을 기준으로 3조9,000억원 규모로 전년대비 15.8%의 성장을 보였으며, 2006년에는 5조7,000억원 규모의 시장을 형성할 것 으로 전망되고 있다. 특히 온라인게임 시장은 2004년 1조원 시장을 돌파할 것으로 예상된다. 또 국내 게임시장은 해외시장에서 5.3%를 차 지하고 있으며, 온라인게임은 세계시장의 31.4%를 점유, 1위를 기록하고 있어 게임산업이 한국 문화산업을 대표하는 비즈니스로서의 가능 성은 더욱 커지고 있다. 게임산업은 게임 플랫폼과 관련 환경에 적합한 새로운 게임의 개발 여부가 게임산업의 성패를 가늠하며, 이와 같이 빠르게 변화하는 게임시장에서 독점적 우위를 고수하기 위해서는 게임산업의 환경 전반에 걸친 다양한 정보의 수집,제공이 절실하게 필요 하다. 이에 11월의 DB 서비스 평가는 게임산업 전반에 걸친 다양한 정보를 데이터베이스로 구축해 서비스하고 있는 한국게임산업개발원의 ‘게임종합정보시스템(www.gitiss.org)’을 평가해 보고자 한다.

The scale of game development are rapidly increasing as the blockbuster games which cost $7\~20$ billion won, often appear on the markets. The game mechanics which is concentrated on technological elements of the game, necessarily requires the management of quality. In this paper, we propose a computer simulator for the quality evaluation of game mechanics which can analyze the quality accurately and economically in the design phase. The proposed simulator provides Petri net[7,8] and Smalltalk[9] for convenient modeling. The simulator gives the realistic evaluation like play test because it uses the realistic data of gameplay environment such as player action-pattern, game world map, and item DB but the previous evaluation methods can not consider the realistic gameplay environment and can only cover a limited scope of evaluation. To prove good performance of the proposed simulator, we have 80 simulations for the quality evaluation of the game mechanics of Dungeon & Dragon[13,14] in a given world map. The simulation results show that the proposed simulator can evaluate the faultlessness, optimization, and play balance of the game mechanics and gives better good performance than other evaluation methods.

CEP(Complex Event Processing) is a technique to find complex event pattern in a massive information system. Based on CEP technique, an abuse pattern monitoring method has been developed to provide an real-time detection. In the method, the events occurred by game-play are observed to be against the rules using CEP. User abuse patterns are pre-registered in CEP engine. And CEP engine monitors user abuse after aggregating the game data transferred by game logging server. This article provides the performance analysis results of the abuse pattern monitoring method using real game DB. We results that the method proposed in previous study is effective to monitor abusing users.

최근 다양한 게임 문화가 급속도로 성장함에 따라 보다 새로운 개념의 게임을 찾는 사용자의 요구가 증대 되고 있다. 기존의 게임은 획일화 되고 일방적인 사용자 환경으로 사용자가 일방적으로 게임을 하는 방식이었다. 때문에 사용자의 감성 데이터를 이용하여 사용자에게 게임 환경이 맞춰지는 "사용자 맞춤형" 게임은 기존의 게임에서 보다 진보한 새로운 방식이 될 것이다. 이 방식을 사용하기 위해서는 우선 사용자의 생체 데이터나 감성데이터를 포함한 뇌파를 획득하는 방법이 필요하며 다음으로 획득된 뇌파를 통하여 현재 사용자의 감성 상태를 규명하는 패턴인식 기법이 중요한 문제가 된다. 본 논문에서는 뇌파를 통하여 현재 사용자의 감성 상태를 규명하고 인식할 수 있는 패턴인식 기법으로 Multi Layer Perceptron(MLP)을 사용한 감성인식모델을 제안한다. 본 논문에서 제안한 감성인식 모델의 실험을 위하여 특정 공간 내에서 여러 사용자의 감정별 뇌파를 측정하고 실험을 통하여 획득한 데이터로 감정 DB를 구축한다. 구축된 DB를 본 논문에서 제안한 감성인식 모델로 학습을 하고 학습이 완료된 후 새로운 사용자의 뇌파를 입력 받은 후 현재 사용자의 감성을 인식한다. 감성인식과 더불어 집중도를 측정 하는 실험도 병행 한다. 본 논문에서 제안한 감성인식 모델의 성능을 측정하기 위하여 사용자의 수에 따른 감성 인식률을 측정함으로서 본 논문에서 제안한 감성인식 모델의 성능을 확인한다.
