Objective: The purpose of this study was to explore the effects of a senior functional game (Rejuvenescent village) on cognitive function, instrumental activities of daily living (IADL), depression, and life satisfaction in Korea. Methods: An one-group pretest-posttest design was used in this study. Data were collected twice (at the beginning and the end) from 100 elderly adults in S city who played "Rejuvenescent village" 8 times (twice per week, one hour per session) for a month. Also they completed questionnaires on their cognitive function, IADL, depression, life satisfaction, and general characteristics. The data were analyzed using SPSS 20.0 programs. Results: The mean age was 70.06(${\pm}3.77$) years, with a range of 65-80 years old. Among 100 subjects, 21% were male and 85% were young old. There were statistically significant differences in cognitive function (t=-3.32, p=.001), IADL (t=1.98, p=.049), and life satisfaction (t=-2.15, p=.034). Although there was no statistically significant difference in mean depression score (t=1.06, p=.292), categorized depression was statistically significant (${\chi}^2=62.97$, p<.001). Conclusion: The findings in this study show that the serious game (Rejuvenescent village) was effective for older Koreans' cognitive function, IADL, depression, and life satisfaction. Thus, we need to consider senior functional games to get health benefits by making elderly adults active with enjoyment.

Purpose: This study was done to investigate the motivational, physical and affective benefits of exergaming in community dwelling older adult women. Methods: The research design was a nonequivalent control group pre-test and post-test design. Sixty-one older adult women over the age of 65 were recruited from 6 community senior centers to participate in the 8 week exercise intervention or control group. Six centers were divided into one of three groups: exergame, qigong exercise, or control. The exergame and the qigong exercise group received 16 sessions, scheduled twice a week, with each session lasting 50 minutes. Test measures were completed before and after the 8 week intervention period for all participants. Measures included: Grip strength, chair stand, 6 m walking, balance, geriatric depression scale, vitality and intrinsic motivation. Results: There were significant improvements in the exergame and qigong exercise group for grip strength, chair stand, 6m walking, balance, vitality and intrinsic motivation at the end the 8-week program compared with the control group. Conclusion: The exergame could be an effective alternative for older adult women to group exercise classes.

In this study, we developed a visual novel game as one of the donation campaign strategies. In study 1, we developed a visual novel game for the elderly who live alone. In study 2, we also examine how game affects personal distress and empathic concern, the emotions that trigger help behavior. The results showed that game can promote both emotions effectively. Moreover, empathic concern completely mediated between game and donation intention. This result suggests that visual novel games can be an effective tool for stimulating user's altruistic motivation to do donation behavior.

PURPOSE: The purpose of the present study is to investigate the changes in the cognitive function of elderly dementia patients residing in a residential care facility, following six weeks of brain-computer interface (BCI)-based cognitive training and to determine whether BCI-based cognitive training effectively improves their cognitive functions. METHODS: Thirty subjects diagnosed with dementia were randomly assigned to either the experimental or control group. Pre- and post-test cognitive function assessments were conducted using the mini mental state examination-Korean (MMSE-K) and Korean-dementia rating scale (K-DRS). The experimental group received BCI-based cognitive training, which consisted of games such as flying a ball and exploding a bomb, while the control group participated in music listening activities and National Health Gymnastics. Both groups engaged in a total of 18 sessions (3 times per week for 6 weeks, for 40 minutes per session). RESULTS: After 6 weeks of intervention, the experimental group had significantly increased MMSE-K scores ($19.53{\pm}1.30$ to $22.20{\pm}1.15$; p<.0011) and total K-DRS scores ($87.20{\pm}4.16$ to $99.33{\pm}1.15$; p<.0011). In addition, the experimental group showed greater cognitive improvements than the control group. CONCLUSION: The results of this study suggest that BCI-based cognitive training is a positive intervention tool for improving the cognitive function of dementia patients.

In this paper, we analyzed the effects of game-based visual feedback training on postural balance control in young adults and older adults. We provided postural balance training by 23 young adults and 14 older adults and for four weeks in fifth minute a day and three days a week using IBalance(Cybermedic Inc., Korea). We evaluated the ability of postural balance using balance SD(Biodex, medicalscience Inc., USA) for the validation of game contents based on visual feedback training program. The results showed that postural stability and limits of stability of young adults and older adults were improved significantly before and after the training(p<0.05). Thus, the games of postural balance encouraged anterior, posterior, medial, lateral and multidirectional weight shifting regarding postural balance. Our study indicates that postural balance training of visual feedback based game could be adapted for improving postural balance. Moreover, we could develope of game contents for individuals and various ages for effective application of this game-based visual feedback training.

Smartphone use has become a part of everyday life, not only for adolescents but also for elderly and older people. Thus, this study explored the effect of demographic variables, the amount of smartphone usage, type of smartphone use and psychosocial variables on smartphone dependence of the elder group. We analyzed the data of 5627 (50s and 60s) of the Internet overdependence survey data of the Korea Information Society Agency in 2016. As a result of hierarchical multiple regression analysis, More frequency of smartphone use of weekday and weekend, and usage time of smartphone of weekday were related to greater smartphone dependence. More smartphone use for information seeking and games were associated with greater smartphone dependence. And, as loneliness and anxiety increased, smartphone dependence increased, while smartphone dependence decreased, as social capital increased. Through this study, it is necessary to understand characteristics related to smartphone dependence of elder and older group, and to use this knowledge to solve their smartphone dependence. Future studies also need to identify the causal relationship between predictors of smartphone dependence in elderly and older people.
