In order to solve the problem that the current network security situation assessment methods just focus on the attack behaviors, this paper proposes a kind of network security situation assessment method based on Markov Decision Process and Game theory. The method takes the Markov Game model as the core, and uses the 4 levels data fusion to realize the evaluation of the network security situation. In this process, the Nash equilibrium point of the game is used to determine the impact on the network security. Experiments show that the results of this method are basically consistent with the expert evaluation data. As the method takes full account of the interaction between the attackers and defenders, it is closer to reality, and can accurately assess network security situation.

In this paper, we propose a modeling and simulation of group behavioral movement of pedestrians using Agent based and Cellular Automata model in intelligent game environment. The social behaviors of the crowds are complex and important, and based on this, the prototype game-model was implemented to show the crowd interaction on AB and CA in the game environment. Our experiment revealed the promise of group behaviour as a cost-efficient, yet accurate platform for researching crowd behaviour in risk situations with real models.

One of the most important reasons for using online game is intrinsic motivation which relates the drive to perform a behavior for perceptions of pleasure and satisfaction from the behavior itself. Therefore, most studies for using online game have been based on theories for intrinsic motivation such as flow. However, such theories have some limitations for explaining social aspects of online games such as Massively Multiplayer Online Role Game (MMORPG), which provides a society for game players by using a virtual space for playing games so called 'persistent world'. Adaptive structuration theory (AST) is one of trying to capture the change of using IT due to social interactions between users and system. In order to explain online game players' behavior considering social interaction, we suggest a research model based on AST. Our model aims to investigate the relationship between appropriation which is determined by faithfulness of appropriation (FOA) and consensus on appropriation (COA) and performance which is represented by the relationship among perceived winning, flow, and intention of reuse. An empirical test of our model for 125 MMORPG users which is analyzed by Partial Least Square method shows very satisfactory and interesting results. While hypotheses suggested in our model are supported, the influence of COA on game performance is shown to be stronger than that of FOA.

This research will suggest a Digital Physical Field Game (Digital PFG) as a new ubiquitous paradigm. Based on the evolution of videogame paradigm which is affected by the social paradigm evolves, meanings of "participation" and "communication" as an interaction in the videogames are examined. Additionally, a general concept of ubiquitous games and its limitations are also investigated. Based on that, a new game paradigm which contains a concept of ubiquitous games, Digital PFG's main concepts and examples are newly designed and proposed. As contributions of this research, next are expected, such as, improved immersive contents for the serious games and new approaches to the theme and science parks design as a user participated digital contents.

Currently social games with an emphasis on the relationship between the friends, especially women customers, have contributed to the expansion of game market attracting large audiences. Though recent interest in social games and the explosive propagation of social game into game industry, scholarly research for social game is insufficient. The objective of the study is to explore the success factors for successful social games. We suggest the guidelines for development of social game. Commercial success of social games and the number of users with the best game, farmville, were investigated for understanding key success factors in social game field. As a result, social interaction, simple interface, non-dynamic methods, instrumental rationality factors have been identified. This study will expect the guideline in order to develop a successful social games.

The current study examined how different level of self-constol and construal level influences game users' game addiction. Also we explored the interaction effect between the individual's self-control and construal level on game addiction. To answer the research questions, we conducted an online survey and total 918 participants were selected for the final analysis. According to the results, users with low level of self-control and low-level construal showed higher level of game addiction. In addition, we found a significant interaction effect between self-control and construal-level on game addiction. In high self-control group, game addiction level was low regardless of level of self-construal. However, in low self-control group, the level of construal-level affected game addiction. We found that construal-level played an important mediating variable. These findings suggest a noble insight for autonomous control in alleviatinggame addiction by changing one's level of self-control and self-construal.

This paper describes a 3D modeling system in Augmented Reality environment, named 3DARModeler. It can be considered a simple version of 3D Studio Max with necessary functions for a modeling system such as creating objects, applying texture, adding animation, estimating real light sources and casting shadows. The 3DARModeler introduces convenient, and effective human-computer interaction to build 3D models. The 3DARModeler targets nontechnical users. As such, they do not need much knowledge of computer graphics and modeling techniques. All they have to do is select basic objects, customize their attributes, and put them together to build a 3D model in a simple and intuitive way as if they were doing in the real world.

The mobile game environment is rapidly expanding with AR (augmented reality) technology along with artificial intelligence. In particular, AR (Augmented Reality) technology is a field of VR (Virtual Reality), which is a technology that shows a mixture of virtual information and images in a real environment. Recently, research on mobile UI design based on the interaction based on the augmented reality technology has become important at the point when various utilization methods are suggested based on understanding of contents. There are still some issues in terms of whether the consumer can utilize it in various ways, unlike the developed supply system. In this paper, we present an example of mobile UI design based on interaction based on smart media augmented reality through previous study and literature study of smart augmented reality to solve problem UI issues based on background theory.

On top of presenting the possibility of expanding the game space to social space through mobile communication, MSNG reinforces the strengths of SNS and the fun of games through closer networks between users. This study empirically verified the effects of the characteristics of MSNG on interactions and user satisfaction by dividing the main characteristics of MSNG into graphics, challenge spirit, and reward, and then dividing the main characteristics of mobile social network service into social interaction and technical interaction. In the results of study, the main characteristics of MSNG such as graphics, challenge spirit, and reward all had significant effects on the social interaction and technical interaction while the social interaction and technical interaction of MSNG also had significant effects on the user satisfaction, so that the hypotheses of this study were all selected. The influence of the characteristics of MSNG on interactions might be because of shared feedbacks through graphics, game tasks, and reward in the performance process of MSNG, and such interactions make diverse people have the horizontal or circular communication, which is led to the increase of user satisfaction.

It is said that today is an era of total cord characterized by the transition from the industrial society to the knowledge based and information one. In this age of total cord, the most complex media production is the game industry. In the game industry, game character as one of the elements of game production is the most important because it contains visual elements created through interaction with a user. Initial creation of characters in the game industry is considered having the most value-adding element. Character creation in game production begins with basic drawings, like a diffusive property of the production elements, and proceeds to complicated 2D game character illustration and 3D game character production. In addition, only when driving forces for game development such as individuality and virtual reality are based on different mind cord from existing one, foundation for it will be firmly established. Therefore, it is clear that understanding of the Importance of character illustration and original drawings in the game production is essential to successfully produce more perfect 3D game characters.
