제 3 세대 이동 통신인 IMT-2000 서비스의 목적은 언제 어디서나 어떠한 환경 하에서도 고품질의 영상과 신뢰성 있는 멀티미디어 서비스를 제공한다는 점이다. 기존의 2 세대 이동통신에서의 엔터테인먼트 서비스가 텍스트 기반의 온라인 게임이나 단순한 이미지 및 그래픽 파일 그리고 저 해상도의 영상만이 제공되었다면 IMT-2000 상에서의 엔터테인먼트 서비스는 개인화가 부각된, 눈으로 보고 느낄 수 있는 고 부가가치의 영상서비스를 제공 할 것이다. 사용자는 정지 또는 이동 중에도 IMT 단말기로 3 차원 게임을 즐기고 실시간 또는 주문형 영상 및 음악을 시청하며 여행정보를 수집하는 등의 더욱 더 효과적인 무선 오락을 즐길 수 있도록 기존의 시간 때우기 식의 개념에서 벗어나 자신만의 가상 세계를 체험할 수 있는 사이버 월드의 킬러 서비스로서 기반을 다져가야 할 것이다. 본 고에서는 IMT-2000 엔터테인먼트 서비스와 이에 관련되는 소요기술 등을 기술 하고자 한다.

The paper presents and empirically tests a model of the digital contents(DC) innovation systems that enables us to study interactions between users, service providers, contents developers and network providers, and to examine the relationship between manufacturing innovation and service innovation as well as patterns of innovation in the DC industry. The framework of Gallouj and Weinstein(1997) and Gallouj(2002) is modified into the DC innovation model according to characteristics of the DC industry, that is, user involvement and network externalities. The model is applied to a case analysis that traces the growth of the online game industry in Korea since its introduction. The model offers several advantages over other approaches in understanding the dynamics in the DC industry. Most importantly, it provides a single unified basis within which both service innovation resulting from users and service providers and manufacturing innovation induced by contents developers, platform holders and network providers are analyzed. The distinction between service and manufacturing innovation is important in many ways, for instance in selecting proper government policy tools for promotion or regulation of the DC industry. Second, the Korean online game industry has experienced both radical innovation during the beginning period and non-radical innovation throughout the maturation period. The model developed herein helps to illustrate several types of non-radical innovations such as recombinative innovation that are crucial to sustainable development of the DC industry. Third, the model clarifies impacts of network externalities that are characteristics of the DC industry.

Forecasting game usages hours can supply good information resolving intensive server access and ensuring stable game service. In this paper, we applied various time series analysis methods to forecast game usage hours in 2009 on famous "Ion" and "Sudden Attack" games. According to the experiment, the seasonal variation method showed better performance forecasting actual usage hours.

어느덧 2005년의 숫자가 선명한 달력이 자리를 차지했다. 개인적으로 2004년을 돌아볼때, 그 어느해 보다 뜻 깊은 한해였다. 5년간 심혈을 기울여 준비했던 SF MMORPG RF온라인을 선보여 게이머를 비롯해 업계 관계자들의 성원이래 성공적으로 서비스를 진행했기 때문이다. 이와 같은 RF온라인의 성공은 2004년 계획을 수립하는데 있어 더욱 큰 기대와 긴장을 느끼게 한다.2005년 을유년을 상징하는 닭은 다섯 가지 덕이 있다고 했다. 머리에 있는 볏은 문을 상징하고, 발은 내치기를 잘한다 하여 무라했으며, 적과 맹렬히 싸우는 용이 있다고 했고, 먹이가 있으면 자식과 무리를 불러 먹인다하여 인이 있고, 하루도 거르지 않고 시간을 알려주니 신이 있다고 평가했다. 이와 같은 닭의 특징은 창으로 인상적이다. 앞서 언급했던 RF온라인은 캐주얼 게임으로 국민 게임이라 불릴만큼 기세를 떨쳤던 포트리스 2 블루가 정점을 달릴때 시작됐다. 한달 37억원까지 달했던 매출로 성공에 대한 기쁨에 취하기도 잠시, 바로 차기작 개발에 착수 했던 것이다.

To get a better profit, standalone mobile game market shifts network-based mobile game. Currently, most of the game platform are separated into mobile to mobile, desktop to desktop, and console to console. Multi platform network game has a diverse problems including consistency control, object management technique, and bandwidth inconsistency. n this paper, we will introduce a multi-platform arcade game "Push-Push", which is played on desktop to mobile environment. The game guarantees realtime play between heterogeneous machine users and game item sharing between two platforms. e will focus n the issues of the 3rd generation multi platform games and propose some techniques or solving these problems. Our server database is implemented on MS SQL database, also the desktop programming tool is Visual Basic, and WIPI(Wireless Internet Platform or Interoperability) as a mobile platform.

The investigation results were as follows. First, only 17.5% of adolescent knew a shutdown system. Second, they were recognizing about the game poisoning seriously. Also the half degree thought them efficiently about a shutdown system introduction. The policy about a shutdown system introduction were as follows. First, public education is activate, and we must keep adolescent from exposing to private education in the entrance examine competition. Second, we need the thing to increase the conversation time of the children with put parents to develop desirable family education program.

In the security field, log analysis is important to detect malware or abnormal behavior. Recently, image visualization techniques for malware dectection becomes to a major part of security. These techniques can also be used in online games. Users can leave a game when they felt bad experience from game bot, automatic hunting programs, malicious code, etc. This churning can damage online game's profit and longevity of service if game operators cannot detect this kind of events in time. In this paper, we propose a new technique of PNG image conversion based churn prediction to improve the efficiency of data analysis for the first. By using this log compression technique, we can reduce the size of log files by 52,849 times smaller and increase the analysis speed without features analysis. Second, we apply data mining technique to predict user's churn with a real dataset from Blade & Soul developed by NCSoft. As a result, we can identify potential churners with a high accuracy of 97%.

최근 코로나바이러스감염증-19(COVID-19)가 확산됨에 따라 화상회의, 온라인 게임, 스트리밍 등과 같은 다양한 온라인 서비스들의 트래픽이 크게 증가하면서 원활한 서비스 제공을 위한 서버 자원 관리의 중요성이 강조되고 있다. 이에 따라 서버 자원을 전문적으로 관리해주는 클라우드 서비스의 수요도 증가하는 추세이다. 하지만 대다수의 국내 기업들은 성능의 불확실성, 보안, 정서적 이질감 등을 이유로 클라우드 서비스 도입에 어려움을 겪고 있다. 따라서 본 논문에서는 클라우드 서비스의 성능의 불확실성을 해소하기 위해 클라우드 시장 BIG3 기업(아마존, 마이크로소프트, 구글)의 클라우드 서비스의 성능을 비교하였다.
