The preliminary security assessment is an information security process to analyze security weaknesses before beginning of services. Discovering security weakness through preliminary security assessment is highly required because it costs much when security incident occur in the middle of service operation. However, this assessment is not widely spread in the online game service domain yet. In this paper, we summarize the security risk existed in the online game service, and we classify the security requirements related to the each risk. Also, through the case study, we evaluated the effectiveness of preliminary security assessment in this domain. In addition, we suggest checklists that should be reviewed once in game-client side, network-side and game-server side for the purpose of security enhancement.

The purpose of our research is to identify the critical variables and to develop a new methodology for market segmentation of online game market. Our research tested the model with Korean online game users because Korean online game industry is the frontier of global online game industries. Conclusively, the critical variables are the suitability of feedback, the reality of design, the precision of information and the involvement of virtual community. The analysis of segmentation shows that the primary target audiences are positively influenced by the reality of design and the involvement of virtual community. To attract the primary target audiences, online game companies should develop strategies depending on the effectiveness of the variables and the demographic and behavioral characteristics of target audiences.

Group features such as group cohesion and consistency on appropriation(COA), which have been constructed through social interactions, should be noted for characterizing online game, especially, clan based massively multi-players online game (MMOG). This study attempted to identify the relationship between group characteristics and users' effectiveness of MMOG considering group experience. For this purpose, a research model was suggested: group cohesion and COA are variables for explaining group features, perceived use control is a variable for individual competency of playing MMOG, and perceived winning and perceived enjoyment are dependent variables. Moreover, group experience was included as a moderating variables for two relationships, group cohesion-preceived winning and COA-perceived winning. For the validation of this research model, 100 users for Sudden Attack which is one of very well known MMOG games were surveyed by questionnaires. Before survey, they were grouped into 10 teams and were played over ten times by team for perceiving group consciousness. In result, most hypotheses were statistically supported except the relationship between group cohesion and perceived winning.

The traditional methodology of online game development is separating server development module and cilent development module. However developing and maintaining expenses have been increased a lot due to duplicated modules such as definitions of network protocols and managements of planning data. In this paper, we suggest an advanced methodology of online game development based on the integrated single module with client and server. Its effectiveness was shown by applying the proposed methodology in the development of the online game 'Chungmukong's Battle on the Sea'. In this case, the project size was reduced by 15.1% by using the integrated single module with client and server.

This study is to examine relationship between immersiveness aspect and the recognition of garners who are exposed to PPL (Product Placement Advertisement) in online game. The frequency of exposure, the placement type of PPL, the perception under the threshold of consciousness and the interest at the product and knowledge about PPL have been widely known as the factors of effectiveness in PPL advertising. In this study, 'immersiveness' is newly introduced to investigate the effectiveness of PPL advertising due to the unique characteristics of game which easily leads to immersion. Control group is exposed to movie clip and experimental group to lacing online game. In conclusion, the deep immersion has reduced the perception level of user on PPL except the variable of PPL placement. This study suggests that how to design the PPL placement in game for enhancing marketing effect is all the more vital, in spite of the result that the player in high immersion cannot distinguish different images.

Recently, a Game Shut-down policy, partially limiting the time for the use of online game service, has been implemented in order to protect the youth from the excessive use of games by limiting their access to games in the late hours, based on the serious side effects of online games on the youth. However, the effectiveness of a Game Shut-down policy becomes a social issue. Thus, this study aims to investigate the alternative policies through the levels of the communications suggested by the theory of excellence, for the successful implementation of the policy. As a result of the study, the government and students, the recipient of those policies, need to strengthen their two-way communication in respect of the Game Shut-down policy, breaking from the existing views on the perception. The problem is that the current government's way of the communication for the Game Shut-down policy is one-way and it is aiming at achieving the objectives only. Thus, the communication in this manner will cause the side effect. 'the opportunistic violation of the system in the future', even if the students seemingly accept the system. Two-way communication will enhance the motivation for the voluntary acceptance of the system and lower the motivation for the opportunistic violation of the system. Thus, the government needs to strengthen two-way communication in the future.

Although the constructivistic instruction is emphasized in these days, many teachers feel burden to implement their teaching based on constructivistic teaming theory. As the main reason for this, difficulty to find out effective materials which can be utilized in the constructivistic instruction can be argued. According to recent studios, effectiveness of online games as the educational material was proven. Based on this result, the possibility for utilizing online games as effective educational materials in the constructivistic instruction was discussed in this study. For this, total process for the business strategy lecture implemented to 50 students in Chung-Ang univ. during 9 months by utilizing an online game named 'Goonzu' was reviewed by the perspective of constructivistic teaming theories. As a result of this review, it was proven that constructivistic methodologies were applied effectively in that lecture. Based on this, the possibility of utilizing online games as the effective material in the constructivistic teaming activity is discussed in this study.

In an Unity engine for multi-player online games, the main thread processing game logic must be separated from the network thread that is responsible for network packet communication. Packet communication between the network threads needs to drop packets that overlap in order to improve the rendering speed. In this paper, the packet discard policy of network thread is proposed for an Unity engine for multi-player online games. The proposed method is the hybrid method of both Partial Packet Discard and Periodic Packet Discard methods to improve the rendering speed by periodically discarding overlapped network packets managed by the queue. The rendering speed of the proposed method is analyzed and its effectiveness is verified by various packet generating simulations of the Unity engine for multi-player online games.
