This study is an investigation of children's video and computer games usage. The respondents included 286 third and fourth grade children, of whom 152 were boys and 134 were girls. The participants were selected from a pair of elementary schools in Seoul. The instruments used consisted of children's self-reported computer game use and their evaluations of the video and computer games. I employed frequencies, percentiles, means, Chi-squares, 1-tests, one-way ANOVA, and the Scheffe Test. Ninety-five percent of the children interviewed reported having played video and computer games. Among these children, most reported that they played the games 2 to 3 times per week for 112 to 1 hour each time. The most common reasons given for playing was 'fun'. The most popularly played games included themes of action, adventure, violence, and competition. There was a significant gender difference in playing and usage. Boys played games longer than the girls. Boys played the games with their friends while the girls played the games with their siblings. Children who played these games longer perceived themselves to be faster, more attentive, and more stable than children who played for a shorter period of time.

In this paper, I had tried to analyze the relationship between the time assigned for computer usage and weakening eyesight. First of all, students classified by gender, school year, eyesight, and wearing glasses along demographic characters took part in a poll, and The questionnaire included questions about computer time, factors of weakening eyesight, and purpose of computer use. The finding in this analysis composed of a cross-tabulations between annual eyesight change and the factors to change their eyesight is that 63.6 % of 165 students participated in this survey weakened their eyesight within a year. To show a correlation between computer usage duration and worsening eyesight in this paper, regression analysis indicated weakened vision by computer usage duration per day and week instead of a year. In addition, according to the analysis between computer usage duration and weakened vision for the people who wear glasses or not trough Independent-Samples T test, weakened vision was shown in computer usage duration per day and week, but not shown in the duration by the year. Therefore, weakening vision was also worse for the people who didn't wear glasses than the others. This study indicated 24..5% of teenagers had poor eyesight by using their computer. According to the frequency analysis on purposes of computer usage, the biggest purpose accounting for 36.4% of the total was the computer usage as a game consol, and the computer as a learning tool was the next biggest purpose at 32.1%. This paper showed the correlation between computer usage time and a factor of weakened eyesight through an analysis of the factor. Therefore, schoolchildren's parents should be more interested in their computer usage.

Purpose: The purpose of this study was to explore factors related to internet game addiction for adolescents. Method: This study was a cross-sectional survey, and data was collected through self-report questionnaires. Data was analyzed using the SPSS program. Results: In logistic regression analysis, the risk of being addicted to internet games was 2.22 times higher in males than females. Adolescents with low and middle academic performance also had a higher risk(2.08 times and 2.54 times) to become addicted to internet games. For the location of the computer, the risk of becoming addicted to internet games were .01 times lower in the living room or brother or sisters' room than in their own room. The risk of becoming addicted to internet games was 1.18 times higher in the higher usage time of internet games. The risk of becoming addicted to internet games was .49 times lower in the more accepting and autonomic parents' rearing attitude and .02 times lower in the high self-efficacy group than the low group. Conclusion: The result of this study suggests that there are noticeable relationships between internet game addiction and gender, academic performance, location of computer, usage time of internet games, parents' rearing attitude, and self efficacy.

The purpose of this study was to analyze the effects of computer game usage time on trunk muscle thickness and pressure pain threshold. The 33 study participants were divided into Group A, which spent less than 10 hours per week playing computer games; Group B, which spent between 10 and 20 hours per week playing computer games; and Group C, which spent more than 20 hours per a week playing computer games. The thickness of the participants' upper trapezius (UT), pectoralis minor (PM), anterior scalene (AS), and middle scalene (MS) muscles as well as the pressure pain threshold of their UT, PM, AS, MS, and levator scapular (LS) were measured. The study found that the PM, AS, and MS muscle thickness in group C was significantly greater than in the other groups (p<.05), and the UT, AS, PM, and LS pressure pain threshold in group C was significantly lower than in other groups (p<.05). Therefore, those who use computers for a long period of time during the week should recognize that their computer usage may cause musculoskeletal disorders.

To improve the overall performance and realism of your game, it is important to calculate the trajectory of a projectile accurately and quickly. One way to increase realism is to use a ballistic model that takes into account factors such as air resistance, density, and wind when calculating a projectile's trajectory. However, the more these factors are taken into account, the more computationally time-consuming and expensive it becomes, creating a trade-off between overall performance and efficiency. Therefore, we present an optimal solution to find a balance between ballistic model accuracy and computation time. We perform ballistic calculations using numerical methods such as Euler, Velocity Verlet, RK2, RK4, and Akima interpolation, and measure and compare the computation time, memory usage (RSS, Resident Set Size), and accuracy of each method. We show developers how to implement more accurate and efficient ballistic models and help them choose the right computational method for their numerical applications.

The purpose of this study was to identify factors affecting Visual Display Terminal (VDT) syndrome for elementary school students in the digital learning environment. Multiple regression analyses were performed to identify the factors affecting VDT syndrome in the digital learning environment. This was conducted with 256 elementary school students in grades 5-6 with more than a year of experience in digital learning. The regression model explained 41% of elementary school students' VDT syndrome in the digital learning environment. Variables significantly affecting VDT syndrome include game addiction, sleep time, and air quality with game addiction as the most influential. In the digital learning environment, VDT syndrome is significant because it has physical and psychological impacts on the growth of elementary school students. Therefore, it is necessary to develop guidelines for ideal computer usage habits for this age group.
