Online game servers usually has been using the static thread pool system. But this system is not fit for huge online game server because the overhead is always up-and-down. Therefore, in this paper, we suggest the new algorithm for huge online game server. This algorithm is based on the prediction-based dynamic thread pool system. But it was developed for web servers and every 0.1 seconds the system prediction the needed numbers of threads and determine the thread pool size. Some experimental results show that the check time of 0.4 seconds is the best one for online game server and if the number of worker threads do not excess or lack to the given threshold then we do not predict and keep the current state. Otherwise we apply the prediction algorithm and change the number of threads. Some experimental results shows that this proposed algorithm reduce the overhead massively and make the performance of huge online game server improved in comparison to the static thread pool system.

By shifting web2.0 users who share information from passive consumption and create their own information and exchange in the form of an active and visible appearance was changing. Most simply and easily with features that can be accessed. SNS is native to Korea me2day, Cyworld, (c) Logs and foreign SNS of Facebook, Twitter and a surge in user FramVille, Mafia War's Game, and many users use to SNG are. SNG's compared to the foreign national is active and not yet is a step. The domestic market, the benefits of this game online games and SNS in vogue these days to incorporate the concept in the market for a new form of the domestic game that the game, SNOG (Social Network Online Game, social networks, online games) to the expansion of flexible development direction, Expand accessibility, expansion of social skills is to present to the three.

Since wireless communication cost is relatively expensive, the mobile games using cellular phones or PDAs are mostly played after being downloaded unlike more updated types of phone-to-phone or online games. In particular, the upbringing games, in which garners foster virtual companion animals or vegetables as their avata, have been spotlighted. It is essential to supply variety of items for upbringing avatas. However, due to diverse tastes for avatas and limited storage of mobile terminals, game manias must download their desired items from homepages. In addition, game developers must inform users through SMS messages whenever a new item is created. To do so, they must link WEB server and WAP server to Call Back URL or ARS. This paper proposed a linkage method suitable for JAVA-based mobile phone operating system. The proposed method will consequently increase life cycle of a game and reinforce profitability.

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."

This paper describes the development of a brickwork game with three-dimensional computer graphics as one of web-based game contents. Client user using web can access and run lava applet program with the independence of hardware system. It consists of graphic user interface module, initial space generation module, event handler module, player control module, and thread control module. It uses 3-D array data structure for the 3-D graphic objects that are located in three-dimensional space for high-speed object searching and sorting. It enhances to compare with predetermined construction 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.

The web is one of the most plentiful sources of images. The web has an immediate need for image processing technology in Java. This paper provides a practical introduction to statistical image processing using Java on the web. The paper describes how images are represented in Java and deals with four image processing operations based on basic statistical methods: point processing, spatial filtering, edge detection and image segmentation.

With the help of information technology, the web 2.0 gives people the environment where they share informations and a means of expressing ideas. The power of web affects interactive storytelling for Alternate Reality Game (ARG). There are less theoretical approaches and practices about ARG in Korea and to understand ARG into a deeper sense shall contribute to the development of domestic culture and its contents. In order to realize this, first we will explore the general idea about ARG. Second, know its elements in Interactive storytelling and finally, analyze the examples.

As future warfare becomes network-centric, war-game simulators require high interoperability between networked forces and dynamic reconfiguration in accordance with war events. In this paper, we propose an event-driven methodology to develop dynamic war-game simulations. Federates are developed by event-driven web services. The event-driven web services consistently sense war events and response them only if they are interested. By the sense-and-response mechanism and asynchronous event processing, we are able to save simulation time. An Anti-Surface-Warfare simulator is constructed to demonstrate the methodology and suggests that event-driven web services are efficient to model and simulate warfare where numerous events are generated from hardware systems and people dispersed on the network.

The nowaday Internet reached in phase that collect ideas of netizens through the Internet now regularly according as offer netizens great many information. In these circumstance, web survey system knows off-line just in on-line the value more do can. However, because participations of many people are important, web survey must be subject that can attract interest of people, and more visual function sees that can lead high hailing degree in active interest and survey more than netizen by offering new interface that provoke interest because is added than uninteresting screen. Therefore, I wish to enhance value still more by doing as can do survey interestingly using web survey system that use flash.
