Smart phone games market is getting bigger. In this circumstance, the Experience game focusing user's activity is popular among the smart phone games because the user can be easily absorbed into the game and felt more sense of unity with the game. there are several studies about game storytelling which focus on story visualization or effective methods of game design, but the study of game storytelling connected with user's activity is not entirely satisfactory. Therefore, in this paper, we introduce a system for user's activity visualization of the experience game for smart phone. To achieve this, firstly, we show the model which is about the overall configuration of experience game for smart phone. secondly, the detail configurations of the overall game model is introduced. lastly, standing on the model, we introduce a simulation model and a developed program.

Purpose: The purpose of this study was to compare the stress level and HPA axis activity of an internet game addiction group and non-addiction group in adolescents. Methods: A cross-sectional comparative study was performed with 140 male high school students from 9 vocational high schools at W city. Data were collected from July to September, 2012, using a questionnaire for measuring internet game addiction and stress level, blood samples for serum ACTH, and cortisol level for HPA axis activity. Data were analyzed using descriptive analysis, $X^2$-test, t-test, ANOVA, and Pearson correlation coefficient with SPSS/WIN 15.0. Results: The stress level of the internet game addicted group was significantly higher than that of the non-addicted group (p<.001). The serum cortisol level was also significantly higher in the internet game addicted group than in the non-addicted group (p<.026). The serum ACTH level was higher in the internet game addicted group more than in the non-addicted group (p<.072). Conclusion: These results showed that internet game addiction could increase stress level and HPA axis activity in high school adolescents. Thus, a nursing approach to prevent and relieve internet game addiction should be initiated to stabilize the HPA axis of internet game addicted adolescents.

BACKGROUND/OBJECTIVES: One ongoing effort to curtail dyslipidemia in school children is through lifestyle intervention. This study analyzes outcomes of the intervention of nutrition education and Javanese traditional game-based physical activity, on lipid profiles of overweight and obese children. SUBJECTS/METHODS: The experimental study consisted of three steps: data collection (October to December 2016), intervention processes (January to March 2017), and final report preparation (April to May 2017). This was a split-plot block study, enrolling a total of 72 subjects. Traditional game intervention (12 meetings) and nutrition education (9 meetings) was carried out within 3 months with material related to obesity. RESULTS: Our results showed no decrease in the levels of total cholesterol in the group receiving nutrition education (rise by 1.56 mg/dL), but when compared to subjects without intervention, total cholesterol levels experienced was increased. The group which did not receive physical activity showed increase in the total cholesterol, whereas the traditional game intervention group showed a decrease of 0.05 mg/dL total cholesterol at the end of the intervention. Nutrition education and physical activity interventions did not influence any reduction in the low-density lipoprotein cholesterol (LDL-C) levels, but rather showed a tendency to increase at the end of the intervention. However, the increase in LDL-c levels in the traditional game group was lower than in other intervention groups. Duncan's test indicated that the effect of nutrition education and physical activity interventions did not differ from the cut-off values of LDL-C and high-density lipoprotein cholesterol. CONCLUSIONS: Total cholesterol and triglyceride levels in the traditional game group tended to decrease at the end of the intervention, but the results did not differ much from other intervention groups. We deduce that nutrition education and traditional game-based physical activity interventions are not capable of improving blood lipid profiles in overweight and obese children within 3 months. It is necessary to increase the time of physical activity intervention to maintain the lipid profile in another study.

Social network games (SNGs), a rapidly growing online game genre, are built and played on social network sites. SNGs provide an online world for enjoying leisure time and interpersonal communication, and an increasing numbers of college students are involved in such game-playing as a leisure time activity. Despite the popularity, relatively few studies have been conducted to investigate the nature of game players, especially the meaning of such leisure time behavior by college students. This paper's aim was to explore a subjective meaning structure of online social network game play. The means-end chain model was used to link attributes of SNGs to the underlying values of game playing as a leisure activity. The results revealed two emerging end-values: the need for bridging and a sense of belonging. This study sheds light on the meaning of college students' leisure activities when playing social network games.

Many users enjoy a location-based augmented reality game such as Pokémon GO. From the perspective of attachment, this paper investigated the antecedents of Pokémon GO use. A total of 182 responses from Pokemon Go users was collected through an online survey. The result of regression analysis showed that attitude toward game characters, social interaction, competition, and physical activity increased attachment to game. Attention switching, however, decreased attachment to the game. This study suggested that attachment to mobile augmented games could be achieved through social interaction, competition, and physical activity. Implications for researchers and practitioners were discussed.

Microsoft released motion sensing device named Kinnect on early 2010, which is available for developing Xbox 360 game and entertainment software. Also many third party libraries and applications are developed for Kinnect. In this paper, we studied and developed guitar rhythm game on Kinnect using three sensor units on it. Rhythm game is the most popular game genre for many game devices including PC, console device, and smart phone. The main reasons for their popularity depends on their simplicity, short learning time and physical activity with rhythms. We developed the game screen and layout on DirectX 11, also we used OpenNI library for recognize physical activity of gamer's body and fingers, and OpenGL for body gestures on the game.

In this paper, we present the research result related to a game application system which improves the symmetry of the left and right brain activity for alleviating the emotional disorders such as anxiety and depression. Since the characteristics of patients with affective disorders are less willing to therapy. obvious motivation is needed in general. To provide a strong incentive for these patients, we propose a customized game system through game-oriented content of enjoyment. After the experiments conducted for 5 days, it was found that the symmetry of left and right brain activity is enhanced. The proposed functional game system can be applied to a wide range of applications such as healthcare or education.

Recently, adolescent's lack of exercise due to increasing physical inactivity is emerging as a social problem. Accordingly, we planned a smartphone game to increase the physical activity of adolescents. The application is able to induce the interest of the youth through the interesting factor of 'game'. Also it provides the user with information about the physical activity by measuring the amount of physical activity of the user through GPS. We propose a way to continuously motivate adolescent's physical activity through this motion interaction game application.
