This study was carried out to investigate the utilization status of internet and dietary information by gender (boys : 442, girls : 461) in school children (total 903). The results were summarized as follows. The most of children used internet regularly (98.1%) and major purpose of using were mentioned as 'game (39.0%)' and 'social intercourse (49.5%)'. The duration of internet use was '< 2hours (80.9%)' They used internet mainly at 'home (88.8%)', and favorite search engines were 'Yahoo (54.2%)' and 'Daum (31.1%)'. The searching experience on dietary information was from only 35.6% of subjects mainly 'for homework (39.6%)' and 'for health (36.9%)'. The satisfaction degree of searched information was 'high (79.5%)'. Dissatisfactory reasons of internet site for dietary information were pointed out to be 'bring little interest (28.9)', 'difficult contents (19.2%)', and 'poor Information (18.2%)'. Only fifteen % of subjects had experience of nutrition counseling using internet, and purpose of counseling was mainly 'for homework (51.4%)' and 'for health problem (24.3%)'. The problems for nutritional counseling site were pointed out to be 'difficult answer content (31.7%)', 'insincere answer (28.6%)'and 'poor answer content (25.4%)'. They acquire information of nutrition and health management mainly through 'internet (43.7%)'. 'Growth and nutrition (28.3%)', 'improvement in studying ability (13.8%)', 'right weight control (13.3%)' and 'cooking (12.8%)'were most frequently asked information, They had a preference for 'game (40.5%)', 'animation (29.9%)' and 'quiz (18.1%)'as loaming method tools. The favorite site color was 'green (51.3%)'The results of this study showed that although the internet use was very high, they used internet to search dietary information very seldom. Therefore, the information donor should find out what is the optimal tool, what kind of dietary information was needed for school children.

While there is no apparent gender difference on the number of game players and playing time in market survey especially if the age group is under 30, there still exists a strong gender stereotype on female characters with sexual objectification especially in team based battle games. Furthermore, there seldom exists any research on female gamers in this genre. In this paper, we investigate the preference of female characters and reasons of their choice among female gamers with Overwatch and Cypers which are recognized as having enough female players. In Overwatch with 231 responses, subjects prefer 'girl-crush' characters such as non-sexual Ana who age is in 60s. However, in Cypers that does not have female warrior character, subjects' preference is more affected by appearance but those characters with less functional ability are not frequently used in playing. Such practical avatar choice is often discovered among male players thus there is no gender difference in this case.

Computational Thinking is an analytical thinking ability that is necessary for everyone and everywhere. The existing Computational Thinking development education provided in Practical textbooks leads to block-based programming languages from unplugged activities. Many unplugged activities focus on practicing sequential order, which may lack the learning of abstractions or automation concepts. In block-based programming languages, concepts such as coordinate planes, which are not introduced in elementary school curriculum, appear, making students feel burdened by the block-based programming language itself. In this study, a curriculum was designed for elementary student's computational thinking through game-based programming language education. The results and their effectiveness were analyzed through the beaver challenge. As a result of analyzing the pre-test and post-test scores, it was confirmed that students' computational thinking skills improved.

The purpose of this study was to investigate the effects of group art therapy on the aggression and emotional regulation ability of elementary school students over-immersed in Internet games. The subjects include 16 elementary school children from H Local Children's Center in S City and G Local Children's Center in Y City. They were allocated to the experiment and control group each of which consisted of eight. Total 12 sessions of Group art therapy were administered to the experiment group twice per week from January 4 to February 15, 2016. Employed in the study were the Internet game addiction, aggression, and emotional regulation inventories. Collected data were treated with repeated measures ANOVA for differences according to the implementation time and group. The findings show that group art therapy had positive effects for mitigating the aggression of elementary school students over-immersed in Internet games and increasing their emotional regulation ability and that those effects lasted. Those findings indicate that group art therapy is effective for alleviating the aggression of elementary school children over-immersed in Internet games and improving their emotional regulation ability. Finally, based on the reuslt of this study, the development and future direction of this program for prevention and treatment of elementary school students over-immersed in Internet games is suggested.

The purpose of the study is to examine sports-related cognitive functions through a systematic review and to suggest effective instruments to measure the cognitive functions. The present study was conducted based on the systematic review and meta-analysis protocol-the PRISMA. Of 429 articles searched through keywords from 2008 to 2020, 45 articles that met the selection criteria were analyzed. It was revealed that athletes had better cognitive functions than non-athletes, that the higher the sports expertise was, the higher the cognitive functions, and that there were differences in cognitive functions according to the sport types. The primary cognitive functions related to sports performance summarized as executive functions (inhibition ability, cognitive flexibility), information processing speed, spatial ability, and attention. As tasks for measuring each cognitive function, a stop signal task for inhibition ability, a design flexibility task for cognitive flexibility, a simple and choice reaction time test for information processing, a mental rotation task for spatial ability, and an attention network test for attention are appropriate.

At the computer games, we can experience a variety of environments using a virtual object. It is similar to that be trained in War-game simulator of the defense. Actual soldiers and a computer-generated virtual group(Computer Generated Force: CGF) in 3-D virtual battlefield environment are training. However, path finding algorithm, one of the techniques of simulation models, to the current level only considers the shortest time path. So, this current level at the special situation of the army in the battlefield for selecting the optimal path is limited. The focus of this paper is to select the least-cost path using the deadline with several different mission conditions(METT+TC). For the only shortest time path algorithm and the least-cost path algorithm using dealine,($d_t$, one of METT+TC elements), Its usefulness is verifying the change of the move spent time(t) for all possible paths and the fighting power of the combat troops(Troops ability, a) through a comparison of the total cost of moves(c(t)). According to the results, when considering the deadline, the proposed algorithm saves about 62.5% of the maximum cost.

Age related decrease of muscle strength, balance, and gait abilities bring about physical inactivity in the elderly. Virtual reality (VR) training has been used successfully to rehabilitate functional balance and mobility in elderly subjects. This study was aimed at determining the effect of VR-based exercise programs by using a video game on the muscle strength, balance, and gait abilities in the elderly. 48 old people were randomly divided into two groups; VR-group (men: 11, women: 14, age: 68.42yrs) and control group (men: 10, women: 13, age: 67.58yrs). VR-group performed an exercise program twice a week for 8 weeks and control group had no intervention. The VR-based exercise program was composed of warm up(10 mins), VR-program(40 mins), and cool down(10mins). It was performed by playstation eyetoy play that provided visual and auditory feedback as well as movements of the upper and lower extremities. Muscle strengths of the knee and ankle were measured using manual muscle tester. Static balance was estimated using computerized posturography. Dynamic balance was measured by Timed up and go test (TUG), Functional reach test (FRT). 10m walk test and 6-min walk test were used to assess gait abilities. After the completion of the VR-exercise program, muscle strength, balance, and gait abilities were improved significantly (p<0.05). In conclusion, the VR-based exercise program showed improvement on the muscle strength, balance, and gait ability in the elderly. This exercise program is both effective and interesting for this age group.
