This paper describes the development of a racing game with three-dimensional computer graphics as one of web-based game contents. Client user using web can access and run java applet program with download of Java Bytecode with the independence of hardware system. It consists of graphic user interface module, initial space generation module, event handler module, and thread control module. It uses 2-D linked list data structure for the 3-D graphic objects that are located in three-dimensional space for high-speed object searching and sorting. It enhances the dynamic object moving and viewing in three-dimensional space. We can use the developed racing game to inform game users of information for an advertisement like tourism information, and can apply the proposed 3-D drawing technology to 3-D game graphic engine core.

다가오는 독일 월드컵을 잡기 위한 포털들의 총성 없는 전쟁이 시작됐다. 네이버, 다음, SK커뮤니케이션즈, 야후코리아, 엠파스 등 국내 대표 포털들은 온 국민의 이목이 쏠리는 월드컵을 활용, 진정한 '포털'로 거듭나기 위해 사활을 걸었다. 더욱이 대형 스포츠 이벤트를 통해 기업 이미지 제고와 회원수 증가라는 실질적인 수익원을 확보한다는 게 업체들의 전략. 특히 하위권 포털업체들은 월드컵 마케팅을 통해 상위권 진출도 모색하고 있어 주목된다.

Third Person Action Game is a genre receiving continuous interest from many game enthusiasts. The most distinctive feature about third person action games is that the user can actually see the character as well as the various actions, which in turn increases user engagement. Many games are developed using game engines. However, this study designs a third person action game using only DirectX library instead of the specialized techniques in game engines. By doing so, the game development costs will be minimalized. The study also uses several basic algorithms in order to process the various events and to make the animation effects more efficiently managed in the graphic device. The performance superiority is demonstrated by the results of the study.

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.

The movie and game are on the center of entertainment industry. The OSMU(One Source Multi Use) method of two media is the most conspicuous in sharing stories. Particularly, the storytelling of a game emphasizes a harmonization between the elements that can be used for a game on narrative point of view(the traditional plot like novel, film and etc.) and the elements reflecting the interactivity, the characteristic of a game. In the gaming made with a film and filming made with a game, the main element of successful storytelling is the story value. In this paper, we describe through the case analysis of the gaming made with a film and filing made with a game in three aspects based on hero's journey steps of Joseph Campbell and $Gr\acute{e}mas's$ actant model theory, which they are the story event, the type and relation of characters, and the complication type between the characters. we, consequently, believe that the compatible storytelling between two media (film and game) and the setting way of characters could be made with the successful diversification in OSMU.

A key challenge in massively multiplayer on-line game(MMOG) systems is providing real-time response latencies to the large number of concurrent game players. MMOG systems are a kind of soft real-time systems because requests from many players should be responded within specified time constraints. Client events have different timeliness and consistency requirements according to their nature in the game world. These requirements lead to tasks with different priorities on CPU processing. In order to meet their timing constraints, we propose priority scheduling methods that attempt to allocate preferentially more CPU bandwidth to serve an task with the higher priority level in the presence of transient overloading. The proposed scheduling methods are capable of enhancing real-time performance of MMOG system by maximizing the number of tasks with higher priority completed successfully within their deadlines while minimizing total average latency of tasks finished after given deadlines. The performance of these scheduling methods is evaluated through extensive simulation experiments.

This paper describes a motivation-based hierarchical behavior planning framework to allow autonomous agents to select adaptive actions in simulation game environments. The combined behavior planning system is formed by four levels of specification, which are motivation extraction, goal list generation, action list determination and optimization. Our model increases the complexity of virtual human behavior planning by adding motivation with sudden and cumulative attributes. The motivation selection by probability distribution allows NPC to make multiple decisions in certain situations in order to embody realistic virtual humans. Hierarchical goal tree enhances the effective reactivity. Optimizing for potential actions provides NPC with safe and satisfying actions to adapt to the virtual environment. A restaurant simulation game was used to elucidate the mechanism of the framework.

Humans are social existences who connect with others and live together. Communication between human has evolved into diverse formats and contents beyond time and space. Social Network Service builds social relationship based on web and its users increase rapidly in a global environment due to the user-friendly web circumstances, easy access and wide-spread supply of the smart phones. One of the aspect that is taking the center of Social Network Service is a Social Game. Social Games are based on web that has simple rules to play in fictional time and space background. This research is to analyze the relationship between social game, Social Network and user behavior through the Social Games Farm Villand Cafe World.This paper, firstly, is going to observe the characteristics of people who participate in the two social games 'Farm Ville' and 'Cafe World'. It, then, attempts to analyze individual and social human desires depicted in the games. In the social games, personal perception is revealed through an image of "possession", while one's social activity is displayed by an image of "consumption."

Many massively multiplayer online games(MMOG) use client-server architectures that have enormous server-side bandwidth requirements. In this paper, we propose a region-based hybrid game architecture that combines the advantages of client-server and peer-to-peer architectures, so that only critical events changing game state are processed by the server. In this hybrid architecture, the central server divides the game into regions and assigns a player as a regional server to distribute important updates for that region. Thus, the central server sends state updates to the players through the regional servers. All players in the same region directly exchange updates without affecting game state. This division of labor greatly reduces server bandwidth significantly and enables it to serve larger number of concurrent players. Our experiments show that the region-based hybrid architecture with three-level hierarchy scales better than the client-server architecture, saving considerable bandwidth at the central server while requiring enough bandwidth of players acting as regional servers.
