온라인게임을 개발하는 과정에서 게임을 검증하기 위한 베타 테스트는 반드시 필요한 과정이다. 베타테스트를 통해 예상치 못한 문제점을 발견하고 사용자들의 행태를 분석하여 단점을 보완한다. 베타테스트를 통해 많은 단점을 보완할 수 있지만 게임컨텐츠가 외부로 공개되며 시간과 비용이 많이 든다는 단점이 있다. 그러므로 본 연구에서는 베타테스트 기간과 비용을 줄이기 위한 방법으로 캐릭터간의 성장 밸런스와 캐릭터간의 전투에 대한 시뮬레이션 모델을 제안하였다. 그리고 이를 트라비아 온라인에 적용하여 개발 기간의 단축을 가져올 수 있었다.

In this letter, we propose blackbox and scenario-based testing of multiplayer online games as well as simple load testing. Game testing is done from outside the source code, and the access to the source code is not required to testers because the game logic is described with a game description language and virtual game map. Instead of using a subset of the main game client for the test client, only game packet protocols and the sequence of packets are analyzed for new game testing. In addition, complex and various scenarios can be tested through combining defined actions. Scenario-based testing helps testers mimic real testing environments instead of doing simple load testing and improves the productivity of game testing.

Objective: This study investigated the effect of a video game-based home exercise program on the improvement of balance and muscle strength in the elderly. Design: Randomized controlled trial Methods: Participants were randomly assigned to two groups: a video game-based home exercise training group (experimental group, n=16) and a control group (n=17). The experimental group trained three times a week for 50 minutes per session for six weeks, and the control group did not perform any exercise. To evaluate postural balance, one leg standing test, Berg balance scale, functional reach test, and timed up and go test were performed, and five times sit-to-stand was performed to evaluate lower extremity muscle strength. Results: In the experimental group, there were statistically significant improvements (p<0.05) in one leg standing test, Berg balance scale, functional reach test, and timed up and go test, and five times sit-to-stand after the intervention, but in the control group, the difference before and after the intervention was not significant. The difference between the groups according to the experimental method showed a significant increase in the experimental group (p<0.05). Conclusions: These results suggest that a video game-based home exercise program effectively improves balance and muscle strength in the elderly. A video game-based exercise program can contribute to the rehabilitation of the elderly as a method of home remote rehabilitation.

Purpose: This study investigated changes in neurocognitive function over a 2-month period of board game therapy in patients with schizophrenia. Method: Twenty-one schizophrenic patients treated with board game therapy and nineteen control schizophrenic patients were evaluated with neuropsychological and clinical tests, such as the Wisconsin Card Shorting Test (WCST). The same tests were re-administered after 2 months of board game therapy. Results: At the first series of neuropsychological tests, no difference was seen in performance, demographical aspects, or clinical severity among both patient groups. After 2 months, the group receiving board game therapy showed significant improvement of WCST performances compared to the controls. However, no difference was observed in clinical symptoms between the groups. Conclusion: The results of cognitive enhancement in patients playing board games indicates that board game play, easily used in an inpatient setting, is a promising tool for executive function improvement in chronic schizophrenic patients.

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: Compared with normal people, stroke patients have decreased voluntary craniocervical motion, which affects their balance. Objects: This study was conducted in order to examine the effects of active craniocervical movement training using a cognitive game on stroke patient's cervical movement control ability, balance, and functional mobility. Methods: The subject of this study were 29chronic stroke patients who were randomly allocated to either an experimental, cognitive game group (n = 15), or control group (n = 14), to which only neuro-developmental treatment (NDT) was applied. The intervention was conducted 5 times per week, 30 minutes per each time, for a total of 4 weeks. Active angle reproduction test, static stability test, limits of stability test, and Time up and Go (TUG) test, respectively, were carried out in order to evaluate cervical movement control ability, static balance, dynamic balance, and functional mobility. Paired t-test was used in order to compare differences between prior to after the intervention, along with an independent-test in order to compare prior to and after-intervention differences between the two groups. Results: After the craniocervical training with a body-driven cognitive game, the experimental group showed significant differences in flexion, extension, and lateral flexion on the affected side, and rotation on the affected side in the active angle reproduction test. The experimental group indicated significant differences in sway length both with eyes-open and with eyesclosed in the static stability test and in limits of stability test and TUG test. The control group to which NDT was applied had significant differences in flexion in the active angle reproduction test and in limits of stability test and TUG test. Conclusion: The above results mean that craniocervical training using a body-driven cognitive game positively influences stroke patient's cervical movement control ability and as a result their balance and functional mobility.
