As video games gain popularity and become a normal part of home entertainment, concern about youth access to inappropriate games continues to grow. Some people have claimed that violent video games influence children's aggressive behavior and that violent video games have some responsibility for violence in the school. In response to people's concerns, the video game industry created a video game rating system in 1995 to help parents decide which video games are appropriate for their children. This study investigated whether parents were aware of the video game rating system and how often they have used it when selecting video games for their children. This study attempted to find relationships among parents' attitudes toward video games, their guidance styles for their children's video game play, and their use of the video game rating system. This study found that most parents have used the video game ratings very frequently when they select video games for their children. But many parents still don't understand the video game rating system. This study showed that parents who had more negative attitudes or less positive attitudes toward video games were more likely to impose restrictions on their children's video game play and to use the video game rating system as a means to restrict their children's access to violent video games.

The objective of this study was to determine the status of star chart game applications in the Google play store in Korea. The share of game genres in paid and free star charts of game applications was searched. Also, the average reviewer's rating, average number of reviews, and average age rating based on the genre of paid and free star charts of game applications, and the average price of paid applications based on genre were analyzed. Hypothesis tests for the differences in average reviewer's rating, average number of reviews, average age rating according to the genre of game applications were performed. Also, hypothesis tests for the differences in average reviewer's rating, average number of reviews, average age rating between the paid and free game applications along with the hypothesis test for the differences in price according to the genre of paid game applications were performed. Lastly, hypothesis tests for the correlation between the start chart ranking and number of reviews in association with the correlation between the start chart ranking and reviewer's rating were performed.

The composition of the 'The Game Story' should reflect the game play and development environment. To do that, I borrowed a coordinate format called 'Spatio-temporal Coordinate Array' that was not based on text-based storytelling. I wanted to create a way for the story to describe relationship between 'action' based on time and 'object' based on space. One way to do this was to analyze the concepts using a mystery game in which Spatio-temporal Array is a large role in user's decision-making. As a result, I found that the method -Spatio-temporal coordinates- was an editor containing game play, and a setting tool capable of being used as a conceptual diagram.

Oculus Rift is the most universal VR (virtual Reality) headset for gamers and FPS (First Person Shooting) is the most suitable game genre to play with VR. Using VR can increase the player's sense of reality and make them feel as though they are in direct contact with the enemy while battling. The suggested VR game is a first person game where the player must defend a specific target against the surging enemy all within the time limit. Many objects will need to be used in this method. Object pooling will be used in order to manage all the numerous objects. When an object is repeatedly created and deleted it typically overwhelms the memory. To resolve this issue the game initially summons the object at the beginning of the scene and afterwards only uses the object when needed, lessening the burden on the memory. A ranking system is implemented to keep the game records in order to stimulate a competitive spirit between the players, and the game has received positive response during test play among college students in their 20s.

Presence, flow, and arousal are interesting user experiences provided by video and people's demand for media which responds to personal interest is getting strong. This research compares video watching and game play by conducting a survey and measuring brain wave to find out the difference of those user experiences in the two media. As a result, all the three user experiences were proved to be significantly higher in game play than video watching. And those EEG frequencies which are known to be related to the state of flow were also measured higher scalp distribution of the game play group. Finally, presence, arousal, and EEG(${\alpha}$, ${\beta}$, ${\delta}$) were found to have influence on the flow state in game play. This research is intended to prove above relations by experiment and make a contribution to the theoretical and methodological improvement in the related area.
