The sound of digital media would be able to perform communication by stimulating body's senses. Because the sound stimuli could arouse a person into the physiological excitement and sensitivity, which appear as the changes of heartbeat, blood pressure, brain waves(EEG) signals. In this paper, we would like to examine whether the game music mixed with relaxing white noises has an effect to relax game player or not through the EEG changes of game players. For the experiment, we divided game players into group A that plays game while hearing game music mixed with white noises, and group B that plays game while hearing game music not mixed. And we measured the EEG changes of the prefrontal lobe between two groups. The result shows that the game music mixed with white noises has an relaxing effect for the left brain, but fall short of the expectations for the right brain. It would be a basic research which will contribute to the development of serious games for psychotherapy using relaxing white noises.

As the online game market grows, the use of game bots is causing the most serious problem for game services. We propose a harvest coordinate analysis model to detect harvesting bots among game bots of the Massively Multiplayer Online Role-Playing Games(MMORPGs) genre. The proposed model analyzes the player's harvesting behavior using the coordinate data. Game bots can obtain in-game goods and items more easily than normal players and are not affected by realistic restrictions such as sleep time and character manipulation fatigue. As a result, there is a difference in harvesting coordinates between normal players and game bots. We divided the coordinate zones and used these coordinate zone differences to distinguish between game bot players and normal players. We created a dataset with NCSoft's AION log and applied it to a random forest model to detect game bots, and as a result, we derived performance with a recall of 0.72 and a precision of 0.92.

In rapid aging society, the disease prevention and management for healthy life of the elderly is very important. Regular physical activity is known to be a useful intervention for the physical and mental health of the elderly. In this study, we explore the convergence contents using IT technology as the intervention for encouraging the regular physical activity in the elderly. There are u-Healthcare and serious game as the convergence of health care and IT technology, and the serious game which is added special purpose such as education, training, and treatment to the fun-one of the game element- can be suitable to provide a variety of contents that leads to physical activity in the elderly. The contents inducing physical activities are "Puffer(ATARI, USA)", "WiiFit(Nintendo, JAPAN)", "Age Invaders(MXR Lab, SINGAPORE)", "Xbox $360^{\circ}$+kinect(Microsoft, USA)", "Tangible bicycle game(Donsin Univ., KOREA)", and "3D Gateball game(Soongsil Univ., KOREA)", and these contents can help health care of the elderly. By increasing physical activity through the use of these contents, it will be able to promote physical fitness and body function required in daily life, disease prevention, and maintain health in the elderly.

Recently many studies has been conducted for interactive game to contents immersion through visual stimuli. Among them, Multi-Plane Image tech is suitable for projecting video in wide views, but it is difficult to perform calibration and mapping tasks for viewing separately. In this paper, we developed a calibration mapping applies to the field archery game space in the form of CAVE. As a result, we maintained the resolution confirmed the space through the video without distortion and expect to be applicable to the fields requiring presence, such as training contents.

In order to strengthen the information security of the organization, it is important to invest in the information security facility, but the information security awareness of the organization members is also very important. Effective education is needed to raise awareness of this information security. However, the method of collective education utilized by most organizations is not very effective. Educational methods using serious games can be a good alternative. Educational methods using serious games have already proved effective through various cases and researches and are used in many fields. In this paper, we design and implement a game program to improve the awareness of individual information security policy importance. The training was conducted for the members of the organization and the change of awareness about the importance of individual information security policy was examined through analysis of evaluation data before and after the training.

The hospital situation, timing, and patient restrictions have become obstacles to an optimum therapy session. The crowdedness of the hospital might lead to a tight schedule and a shorter period of therapy. This condition might strike a post-stroke patient in a dilemma where they need regular treatment to recover their nervous system. In this work, we propose an in-house and uncomplex serious game system that can be used for physical therapy. The Kinect camera is used to capture the depth image stream of a human skeleton. Afterwards, the user might use their hand gesture to control the game. Voice recognition is deployed to ease them with play. Users must complete the given challenge to obtain a more significant outcome from this therapy system. Subjects will use their upper limb and hands to capture the 3D objects with different speeds and positions. The more substantial challenge, speed, and location will be increased and random. Each delegated entity will raise the scores. Afterwards, the scores will be further evaluated to correlate with therapy progress. Users are delighted with the system and eager to use it as their daily exercise. The experimental studies show a comparison between score and difficulty that represent characteristics of user and game. Users tend to quickly adapt to easy and medium levels, while high level requires better focus and proper synchronization between hand and eye to capture the 3D objects. The statistical analysis with a confidence rate(α:0.05) of the usability test shows that the proposed gaming is accessible, even without specialized training. It is not only for therapy but also for fitness because it can be used for body exercise. The result of the experiment is very satisfying. Most users enjoy and familiarize themselves quickly. The evaluation study demonstrates user satisfaction and perception during testing. Future work of the proposed serious game might involve haptic devices to stimulate their physical sensation.

Among the various security threats in online games, the use of game bots is the most serious problem. In this paper, we propose a framework for user behavior analysis for bot detection in online games. Specifically, we focus on party play that reflects the social activities of gamers: In a Massively Multi-user Online Role Playing Game (MMORPG), party play log includes a distinguished information that can classify game users under normal-user and abnormal-user. That is because the bot users' main activities target on the acquisition of cyber assets. Through a statistical analysis of user behaviors in game activity logs, we establish the threshold levels of the activities that allow us to identify game bots. Also, we build a knowledge base of detection rules based on this statistical analysis. We apply these rule reasoner to the sixth most popular online game in the world. As a result, we can detect game bot users with a high accuracy rate of 95.92%.
