Purpose: With the first generation of marriage-based immigrant women in East Asia now reaching their middle or old age, the need to focus investigations on their health-related quality of life has arisen. This study aimed to examine the extent to which physical and mental health, and psychosocial variables can predict health-related quality of life among Japanese middle-aged immigrant women. Methods: This study has a descriptive cross-sectional design. A convenience sample of 197 Japanese middle-aged marriage-based immigrant women from two regions of South Korea were recruited between December 2017 and March 2018. Participants completed self-administered questionnaires on health-related quality of life, menopausal symptoms, depression, perceived health status, disease morbidity, social support, and acculturation. The data were analyzed using hierarchical multiple regression. Results: Depression was the strongest predictor of health-related quality of life, followed by perceived health status, social support, and household income. Menopausal symptoms, presence of disease, and acculturation appeared to have no additional impact on participant's health-related quality of life. Conclusion: In times of rapid growth of global migration and the aging of immigrants in new destination countries, nursing interventions and public health policies for aging marriage-based immigrant women should be prioritized to improve their mental health by facilitating social support and disease management. In addition, social and employment policies that can help immigrant women transition to a healthy midlife are needed.

It is expected that if a viewer feels the higher realism, it will increase efficiency at 3D hologram. Therefore, the purpose of this study is to analyze the effects of the evaluation factors on realism for digital signage using 3D holograms. For empirical analysis, the evaluation factors were derived and built up hypothesis(The evaluation factors of digital signage using 3D holograms will affect the realism). As a result of the experiment, Hypothesis 1 (Social presence) and 3 (Harmony with the space) were adopted while Hypothesis 2 (Graphic's elaboration) was rejected. Finally, research has shown that in order to improve the realism of digital signage using 3D holograms, the contents should be produced in consideration of presence so that the viewers could feel as if they were actually inside of contents rather than expressed extremely well made higher image resolution. Hence, the 3D hologram contents should be installed in a place where it would fit well with the space around it.

In blended learning, which combines school and online learning, unidirectionalness and disconnection of interaction are pointed out as the reason for widening the educational gap. This study conducted focus group interviews with teachers, students, and parents to develop a blended learning model to enhance the effectiveness of online learning. In order to increase the interaction between teachers and students online, the EduCare model considering care factors was proposed. Six practical models were proposed for the blended EduCare model. Not only interaction can be maximized, but learning reality and psychological well-being, social presence can be improved, and the effectiveness of online learning can be cultivated positively.

The purpose of this study is to improve and develop the quality of non-face-to-face classes according to the types of presence by analyzing the effects of teaching presence and learning presence on the learning satisfaction of the non-face-to-face classes that have been suddenly conducted due to COVID-19. For this purpose, a survey on online classes of H University in Gwangju Metropolitan City was conducted to analyze learning satisfaction, teaching presence (learning design, direct promotion), and learning presence (cognitive presence, social presence). The results of the analysis showed that the learning contents of cognitive presence, which is a sub-factor of learning presence, were understood (=.589, p<.001), the direct promotion (=.420, p<.001), and the learning design (=.397, p<.01), which are the sub-factors of teaching presence, were influential in order.This means that the suddenly changed teaching method should have an attitude to improve the intimacy between the instructor and the fellow learners with positive emotional exchange or interaction. The instructor should try to overcome the limitations of time and space through blended learning that is both online and offline for high quality learning design, but the learning medium and learning method considering the physical fatigue of the learner should be developed.

This paper analyzes whether social welfare services converge across the regions. We tested whether local social welfare services converge considering the congestion rate of local social welfare services during the 1985-2013 periods in Korea, using the sixteen higher level local governments panel data. The main findings are as follows. First, the absolute level of local social welfare services converge so that the -convergence exists. Second, the growth rate of local social welfare services increases as the intial level of local social welfare services is lower so that there exists -convergence. The policy implications of our findings are as follows. The local government had better consider the presence of local social welfare services in policy decision making. Also, fundamentally the social welfare policies had better be executed by the central government rather than local governments, since the national minimum welfare must be provided.

Background: Owing to the increase in the aging population, the health problems of the elderly have become important social problems. Social support has a positive effect on improving the quality of life and prolonging the life of elderly people. It is one of the major factors that affects the oral health status of elderly people. The purpose of this study was to examine the relationship between oral health status and social support in elderly people using representative data. Methods: In this study, data from a community health survey in 2015 involving 63,929 elderly people aged over 65 years were analyzed. T-test and ANOVA analyses were performed to compare the general characteristics of and perception about social support. Additionally, a linear regression analysis was performed to confirm the relationship between perceptions about social support and subjective oral health status. Results: We found that sex, age, household income, education level, the presence of a spouse, existence of an unmet dental need, and regular oral check-up had a significant effect on subjective oral health status (p<0.05). In addition, when controlled for all factors, social support has a significant impact on subjective oral health status. Conclusion: The findings indicate that social support is associated with the subjective oral health status of Korean elderly. This suggests that community-level or government investment is required to improve the oral health of the elderly. In particular, policy interventions such as the establishment of facilities that promote social networks, especially facilities based on friendship networks, are needed.

This paper explores how interface environments have an influence on novice users' performance in social virtual worlds (SVWs), which are emerging user-centric three-dimensional cyberspaces. Despite their early popularity, SVWs have experienced that numerous new users leave the cyberspaces soon before they become long-term users. One possible reason is that unfamiliar interfaces of SVWs can be a barrier to novice users' adaptation of the technology. To understand a role of interfaces in the users' assimilation of SVWs, we examine an impact of three interface factors (presence, affordance, and feedback) on performance which is regarded as a yardstick for users' adaptation of SVWs. Forty participants were recruited and went through one-hour experimental sessions with seven tasks in Second Life; they were also asked to answer a questionnaire. Findings indicate that while affordance and feedback are significant factors influencing novice users' performance, presence has no impact on their performance.

In order to predict satisfaction and performance of sensible healthcare game using motion recognition sensor, this study analyzed the effects of flow, presence and social cognitive factor and then, it attempted to verify structural relationships thereof. Self-efficacy, being a social cognitive factor, was found to affect the level of functional satisfaction of health game but it showed no direct effect to intention of using game. Flow experience was also observed to be a meaningful predictor for the level of functional and entertainment satisfaction in the direction hypothesized. It is also shown that presence exerts a direct effect on functional satisfaction. Finally, it is discovered that functional satisfaction has meaningful influence on entertainment satisfaction as well as future intention to use. The results verifies that even in sensible healthcare game, user experience and social cognitive factor have significant effects on satisfaction and performance of a serious game.
