As commercial game engines become available to the public, attempts have been made to use it for general purpose research. This study uses the game engine to develop a medical simulation. Specifically, when the user selects an important portion of the human body, the focus+context visualization is applied to the volume data. We proposes the accumulation based method to make the background part more transparent and naturally fuse it with the focus part. Since the proposed method combines well with the existing volume visualization, the virtual surgery function such as incision is performed smoothly. The game engine is useful for general-purpose research, because auxiliary functions such as collision handling and UI can be efficiently created with the help of it.

The computer game has a narrative structure, which scenario is proceeded by player's consecutive interactive. The interaction is the core of game plays that is not only storytelling in itself, but also is implemented by interface. The UI of computer game is as a tool for communication between player and game, which has been designed by usability on use. However, is it the necessary for us to get synchronization of feelings about game scenario in terms of a psychological in order to deepen the pleasure that is the game's ultimate goal. Effectively, as a way to lead in this empathy. This study tries to application of storytelling to the UI that occurred player's interactive for the first time. Moreover, presented the result as the UI designs of casual MMORPG.

Objective: • To detect black hole and warm hole attacks in wireless sensor networks. • To give a solution for energy depletion and security breach in wireless sensor networks. • To address the security problem using strategic decision support system. Methods: The proposed stackelberg game is used to make the spirited relations between multi leaders and multi followers. In this game, all cluster heads are acts as leaders, whereas agent nodes are acts as followers. The game is initially modeled as Quadratic Programming and also use backtracking search optimization algorithm for getting threshold value to determine the optimal strategies of both defender and attacker. Findings: To find optimal payoffs of multi leaders and multi followers are based on their utility functions. The attacks are easily detected based on some defined rules and optimum results of the game. Finally, the simulations are executed in matlab and the impacts of detection of black hole and warm hole attacks are also presented in this paper. Novelty: The novelty of this study is to considering the stackelberg game with backtracking search optimization algorithm (BSOA). BSOA is based on iterative process which tries to minimize the objective function. Thus we obtain the better optimization results than the earlier approaches.

The wide spread of smartphones and the growth of the number of internet users are reshaping the SNS (Social Network Service). Merging into other service areas and creating new business models with high profits, SNS is no more a service simply providing personal connections. Now SNS has positioned itself as a service platform. SNG (Social Network Game) is a new outcome utilizing SNS as a game platform and showing a rapid growth rate in a short period of time. The number of SNG users is expected to increase steadily. In this study, we examine whether SNG user motivations lead to flow experience and future intention to use. For that purpose, we conducted a survey with smartphone users. The results indicate that flow experience functions as a mediator and user motivations indirectly affect intention to use through flow experience. This paper concludes with discussions on findings and suggestions for future research.

Compared to the past, the number of disabled people in Korea is continuing to increase. As for the scope of the disability, it is expanding as well since it now includes all types of illnesses, car accidents, complications resulting from aging, industrial accidents and others accidents. Attempts are made in terms of applying sports game method that grafts IT technology in order to ensure that the disabled people participate continually in sports. While casting away the notion of play which was the role of a game in the past, new roles and domains were developed. In fact, serious game genre is what leads this change. Because serious game is leading the game industry fast, centered on education, sports, fitness and medical use, its market value can be considered very significant since it can be both fund and effective as it targets the disabled who cannot enjoy sports easily in reality. Accordingly, this research seeks to present the direction for the application of serious game for the disabled people by analyzing the current situation pertaining to the integrated and converged cases applied to the field of sports for the disabled when it comes to the serious game that uses contents based on the IT technology.

Purpose: This study was designed to build a theoretical frame to provide practical help to prevent and manage adolescent internet game addiction by developing a prediction model through a comprehensive analysis of related factors. Methods: The participants were 1,318 students studying in elementary, middle, and high schools in Seoul and Gyeonggi Province, Korea. Collected data were analyzed using the SPSS program. Decision Tree Analysis using the Clementine program was applied to build an optimum and significant prediction model to predict internet game addiction related to various factors, especially parent related factors. Results: From the data analyses, the prediction model for factors related to internet game addiction presented with 5 pathways. Causative factors included gender, type of school, siblings, economic status, religion, time spent alone, gaming place, payment to Internet cafe$\acute{e}$, frequency, duration, parent's ability to use internet, occupation (mother), trust (father), expectations regarding adolescent's study (mother), supervising (both parents), rearing attitude (both parents). Conclusion: The results suggest preventive and managerial nursing programs for specific groups by path. Use of this predictive model can expand the role of school nurses, not only in counseling addicted adolescents but also, in developing and carrying out programs with parents and approaching adolescents individually through databases and computer programming.

We look at Web 3.0 business model canvas (BMC) of metaverse gaming platform, The Sandbox (TS). As results, the decentralized, blockchain-based platform, TS benefits its creators and players by providing true ownership, tradability of decentralized assets, and interoperability. First, in terms of the governance and ownership, The SAND functions a governance token allowing holders to participate in decision and SAND owners can vote themselves or delegate voting rights to other players of their choice. Second, in terms of decentralized assets and activities, TS offers three products as assets like Vox Edit as a 3D tool for voxel ASSETS, Marketplace as NFT market, and Game Maker as a visual scripting toolbox. The ASSETS made in Vox Edit, sold on the Marketplace, can be also utilized with Game Maker. Third, in terms of the network technology, in-game items are no longer be confined to a narrow ecosystem. The ASSETS on the InterPlanetary File System (IPFS) are not changed without the owner's permission. LAND and SAND are supported on Polygon, so that users interact with their tokens in a single place. Last, in terms of the token economics, users can acquire in-game assets, upload these assets to the marketplace, use for paying transaction fees, and use these as governance token for supporting the foundation.

As game markets are rapidly growing, the cost and period of game development are both increasing. These imply that the game development projects require more professional management of the project. Game mechanics is an algorithm of the gameplay on a specific game-platform. Game mechanics is concentrated on engineering elements of the game and its quality should be continuously managed from the design phase to the implementation phase. In the design phase, useful methods that can analyze the quality of game mechanics are the simulations. There are several simulation methods of the game mechanics but each method has limited use range because of its characteristics. In this Paper, we survey the game mechanics simulation methods and analyze the characteristics of each method. By the analyzed results, the Petri net model simulation method is good for analyzing total quality of no-error, optimization, and play-balance of the game mechanics but others are not.

The purpose of this research is to suggest a guideline for direction of content design and resource allocation to make mobile social network game (mobile SNG) production more efficient. We assumed that commercial purpose of mobile SNG is to improve uses' intention of use of the game, and from previous researches we selected flow, social interaction, self efficacy, competition, and reward as the factors which have influence on the intention of use. Finally, improvement of user experiences related to social interaction, self efficacy, competition, and reward is considered as the purpose of the mobile SNG contents. We surveyed university students in Gangwon, South Korea who have used mobile SNG. It took 3 weeks and 244 survey papers were used for analysis. The method for analysis was hierarchial regression analysis using SPSS 18.0. As a result, we found that the user experiences related to self efficacy, reward, competition, social interaction provided by SNG contents are all have positive influence on the user's intention of use and weighed the influence of each factors.
