Purpose: The measure the degree of computer game addiction; to examine the relationship between computer game addiction and contributing factors; and to discover the predictors of computer game addiction of elementary school children of Korea. Method: Data were assembled from questionnaires distributed among 455 children from four elementary schools in Gyung-buk Province. Result: The level of computer game addiction of subjects was rather low, and correlated significantly with gender, academic performance, family economic status, playmates for leisure time, place of playing computer game, length of the habit of playing game, average playing time of game per day, frequency of PC-room(Internet Cafe for game) visits per week, game partners and reasons for playing game. Multiple regression analysis showed that 45％ of the computer game addiction was significantly related to gender(21％), impulsiveness(10％), average playing time of game per day(9％), depression(2％) and other variables(3％) such as playmates for leisure time, academic performance and frequency of PC-room visits per week. Conclusion: We suggest these results be used to develop a computer game addiction prevention program.

This study explores the effects of 'save and load' on game storytelling. In video games, a player can control the game she plays by repeatedly saving and loading game data until she reaches her intended goal. As a consequence, a player can manage the game time. In this article, game time is divided into two parts; play time and story time in order to examine how player's intentions are reflected in game storytelling. This is what distinguishes game narrative from others in that the player generates her own story by saving and loading.

To implement a cloud game service platform supporting multiple users and devices based on real-time streaming, there are many technical needs, including game screen and sound capturing, audio/video encoding in real time created by a high-performance server-generated game screen, and real-time streaming to client devices, such as low-cost PCs, smart devices, and set-top boxes. We therefore present a game service platform for the running and management of the game screen, as well as running the sound on the server, in which the captured and encoded game screen and sound separately provide client devices through real-time streaming. The proposed platform offers Web-based services that allow game play on smaller end devices without requiring the games to be installed locally.

The trend in the domestic MMORPG online game market is on decline because of the change in customers attitude and the advent of mobile or foreign games. The underlying cause of depressed domestic game market is that it has been failing to provide quality service arising from not revising existing game design. For this reason, this paper sets out to gather game users' opinions and to analyze successful domestic and foreign games comparatively to approve the importance and necessity of scenario development and to solve current problems in the MMORPG market. As one solution, this paper proposes a new design method, TIME FLOW scenario technique. This technique aims to establish a system in which story and environment change as time progresses and thus can provide different contents to its users over time. It is expected to enable a new frame for game design environment and to restructure education environment for human resource cultivation.

In this paper we Study a time-optimal model of pursuit in which the players move on a plane with bounded velocities. This game is supposed to be a nonzero-sum group pursuit game. The main point of the work is to construct and compare cooperative and non-cooperative solutions in the game and make a conclusion about cooperation possibility in differential pursuit games. We consider all possible cooperations of the players in the game. For that purpose for every game $\Gamma(x_0,y_0,z_0)$ we construct the corresponding game in characteristic function form $\Gamma_v(x_0,y_0,z_0)$. We show that in this game there exists the nonempty core for any initial positions of the players. The core can take four various forms depending on initial positions of the players. We study how the core changes when the game is proceeding. For the original agreement (an imputation from the original core) to remain in force at each current instant t it is necessary for the core to be time-consistent. Nonemptiness of the core in any current subgame constructing along a cooperative trajectory and its time-consistency are shown. Finally, we discuss advantages and disadvantages of choosing this or that imputation from the core.

In Korea, a lot of people think that the more students spend time in playing game, the more students get their grade lower. So that, parents of students don't want their children play games. But there are few research about the relationship between the playing time of game and a grade of students. Therefore, this research would find the relationship between the playing time of game and students' grade. In result, there is no relationship between the game playing time of a students and the student's grade. A game addict who play game a lot of time a day could have lower grade. But for normal user of game, there is no relationship between the game playing time and the grade.

Current video games and game room games are played as a single player mode on the basis of various emulators. With the evolution of data communications and game technology, a new trend in the game industry has made the primary interests of game developers and companies in the game industry be moved toward a multiplayer mode from the traditional single player mode. In this paper, we represent how to implement a network game platform by allowing network modules to be run in conjunction with the current video emulator games. It also suggests a synchronization scheme for real-time game playout and practical mechanism that can support network games to be played with the Peer-to-Peer process using a lobby system.

The command that game users give should be reflected to the game immediately and should be transferred to several objects at once. Also, all game users who participate in game should keep the same progress situation in Real-Time Strategy game. But it takes a certain amount of time to get the command pass to other users, and it is important issue that many commands are synchronized in a short amount of time on server of RTS game. Therefore we propose a scheme for an efficient synchronization based on event locking method on RTS game in this paper. We design and implement the gaming server applying to our proposed scheme. Also, we show efficiency of our proposed scheme by performance analysis in this paper.

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.

In this paper, we design and implement a mobile game based on Kinect sensor. This game is a motion recognition maze game based on Kinect sensor using XNA Game Studio. The game consists of three stages. Each maze has different size and clear time limit. A player can move to the next stage only if the player finds the exit within a limited time. However, if the exit is not found within the time limit, the game ends. In addition, two kinds of mini games are included in the game. The first game is a fruit catch game using motion recognition tracking of the Kinect sensor, and player have to pick up a certain number of randomly falling fruits. If a player acquire a certain number of fruits at this time, the movement speed of the player is increased. However, if a player takes a skeleton that appears randomly, the movement speed will decrease. The second game is a Quiz game using the speech recognition function of the Kinect sensor, and a question from random genres of common sense, nonsense, ancient creature, capital, constellation, etc. are issued. If a player correctly answers more than 7 of 10 questions, the player gets useful items to use in finding the maze. This item is a navigator fairy that helps the player to escape the forest.
