The purpose of this study was to explore the effectives of a virtual bicycle system in improving the ability of equilibrium sense of normal healthy adults. Experiments were performed to find the factors related to the training of equilibrium sense. The subjects consisted of young and elderly people and the group of young people was compared against the group of elderly people. We investigated three different running modes of virtual bicycle system with two successive sets in total. W measured the parameters related to the running time, the velocity, the weight movement, the degree of the deviation from the road, and the location of the center of pressure (COP). The results showed that the running capability of the elderly became much better after repeated training. In addition, it was found out that the ability to control postural balance and the capability of equilibrium sensory were improved with the presentation of the visual feedback information of the distribution of weight. We also found that the running time and the running velocity reduced when there was no visual feedback information. From the results, our newly developed bicycle system seems to be effective in the diagnosis of equilibrium sense as well as in the improvement of the sense of sight, and vestibular function of the elderly in the field of rehabilitation training.

This study explores the relationships between the division of housework, perceived marital fairness, communication, and marital satisfaction in elderly households. Although the marital relationship is one of the most important factors affecting the quality of life, few studies have focused on marital quality, particularly in the context of older adults. Data were obtained from the 2nd National Korean Family Survey in 2010. The results based on a total of 410 elderly households with couples aged 60 and over indicate significant differences in housework participation between men and women. Women were responsible for most of the housework. According to the regression analysis, the division of housework, perceived marital fairness, and communication independently predicted marital satisfaction, but there were no significant relationships between sociodemographic factors and marital satisfaction. There were significant interactions between the division of housework, perceived marital fairness, and marital satisfaction through communication as a moderator of effects of the division of housework and perceived marital fairness on marital satisfaction. The higher the satisfaction with communication, the stronger the relationship between marital satisfaction and satisfaction with the division of housework was. On the other hand, the lower the satisfaction with communication, the greater the effect of perceived marital fairness on marital satisfaction was. These results suggest that the way in which elderly couples perceive their marital relationships and the level of their satisfaction in interacting with each other play important roles in enhancing their marital quality.

Purpose: Frailty is associated with an increased risk of adverse health outcomes. We aimed to review the relationships between frailty and health outcomes in community-dwelling Korean elderly individuals. Methods: Whittemore and Knafls' framework for conducting integrative reviews was used. PubMed, Cumulative Index to Nursing and Allied Health Literature, and six Korean databases were searched. For analysis, the study included articles written in English and Korean published between January 1960 and June 2018. Of the total 1,488 studies found in the databases, we analyzed 15 studies that met the quality of the evaluation criteria. Results: The prevalence of frailty in Korean elderly individuals ranged from 6.5% to 11.7% when divided into three levels of frailty. The health outcomes assessed in relation to frailty were divided into five domains: quality of life, physical health, psychosocial health, health behavior, and health care quality. Frailty was negatively associated with all five domains. Conclusions: Our study suggested that nurses should be aware of the limitations in the physical and cognitive functions of frail elderly individuals and provide tailored interventions for Korean elderly individuals. Furthermore, a large-scale study is needed to develop the Korean model of the frailty assessment tool and to verify the conceptual model of this study.

Purpose: This study is a pseudo-experimental study of design before and after the non-equivalent control group, which was attempted to verify that the application of the ukulele to the elderly has the effects of reducing depression, improving self-efficacy, strengthening social bonding, and improving cognitive function. Methods: 46 (23 in the experimental group and 23 in the control group) participants were selected. The experimental group was provided with three sessions of a music program using eight Ukuleles for the elderly, while the control group was provided with three sessions for the elderly. IBM SPSS 25.0 was used for data analysis, and the independent t-test, 𝑥²-test, and Fisher's exact probability test were performed to verify the homogeneity of the subject's general characteristics. The effect verification after the experimental treatment was analyzed by Fisher's exact probability test, Friedman test, and Mann-Whitney U test. Results: Depression showed a statistically significant difference between the two groups (F=39.88, p<.001), self-efficacy showed a statistically significant difference between the two groups (z=-4.96, p<.001), social bonding showed a statistically significant difference between the two groups (z=-5.19, p<.001), and cognitive function showed a statistically significant difference between the two groups (z=-3.98, p<.001). Conclusion: It was found that the 'Music Program using the Ukulele' was effective in reducing depression of the elderly, improving self-efficacy, reinforcing social bonding, and improving cognitive function. We hope that the Music Program using the Ukulele can be used in the elderly nursing curriculum in the future, and we suggest it should be applied as a nursing intervention to those who are experiencing cognitive decline.

The purpose of this study is to analyze the health factors of the elderly according to the region by analyzing the physical fitness and fall efficacy of the female elderly living in rural and urban areas. The subjects of this study consisted of 98 female elderly people living in rural and urban areas who exercise health and cheerleading at least twice a week at the regional center(REG; n=46, 77.53±6.37 yrs, 151.81±5.26 cm, 60.00±9.42 kg, UEG; n=53, 73.57±2.70 yrs, 154.07±3.52 cm, 57.37±2.06 kg). Physical strength was measured for muscular endurance, cardiopulmonary endurance, and flexibility. Falling efficacy was measured using 10 items of Fall Efficacy Scale developed by Tinetti et al. Significant differences in flexibility and fall efficacy were found in urban older adults (p<.01, p<.05). There was no significant difference in muscular endurance and cardiac endurance (p>.05). In the future, studies to improve the imbalance of health factors of the elderly in the region should be continuously conducted.

The current study examined the differential effects of giving and receiving social support in the elderly when relationships(family, friend/neighbor) are important. For this purpose, the mediation effects of meaning in life on the relationship between giving and receiving social support and self-esteem were analyzed. Self-reporting data of 310 adults aged over 60 living in Busan and Gyeongnam in South Korea were collected regarding giving and receiving social support, meaning of life and self-esteem. The mediation analysis showed that giving social support had a positive effect on self-esteem with the partial mediation effect of meaning in life. Receiving social support, however, showed no significant mediation effect of meaning in life. This pattern was similar regardless of both family and non-family relations. The result that giving social support enhances self-worth in the elderly through meaning in life suggests the importance of social interaction with intimate others as a source of happiness in the elderly.

This study identified an effective control method for periodontitis by investigating the association between blood levels of vitamin D and periodontitis in Korean elderly based on raw data from the fifth Korea National Health & Nutrition Examination Survey of 2010 (KNHANES). In this study, 1,021 adults over 65 years of age were evaluated based on data from the KNHANES. Periodontal disease was assessed using community periodontal index (CPI), with CPI codes ${\geq}3$ defined as periodontitis. Blood levels of vitamin D were measured from blood samples and divided into four groups (first quartile: ${\leq}13.23ng/ml$, second quartile: 13.24~16.95 ng/ml, third quartile: 16.96~21.58 ng/ml), and fourth quartile >21.59 ng/ml). Using multiple logistic regression analyses, the variables were adjusted for general characteristics, oral health-related characteristics, health-related characteristics, and bone mineral density. The statistical analysis was performed using the SAS (ver. 9.2). The results of this study are as follows: the prevalence of periodontitis was 42.6% in Korean elderly. After adjusting for general, oral health-related, and health-related, the risk of periodontitis in the first quartile group was 1.74 times (95% confidence interval [CI], 1.02~2.98) higher than that of the fourth quartile group (p=0.041). After adjusting for general, oral health-related, and health-related characteristics as well as bone mineral density, the risk of periodontitis in the first quartile group was 1.73 times (95% CI, 1.02~2.96) higher than that of the four quartile group (p=0.042). There was a significant relationship between blood vitamin D level and periodontitis in Korean elderly. For the prevention of periodontitis, factors related to vitamin D should be considered along with other risk factors.

Objective: This study was conducted to provide basic data on physical function improvement activities of elderly care facilities by identifying the degree of physical improvement activities of elderly caregivers. Design: Descriptive correlational study. Methods: The instrument of this study consisted of 12 questions on the general characteristics of the subject. For the assessment of improvement in physical function activities, the measuring tool used for the elderly consisted of a total of 20 questions. For data analysis, Pearson's correlation coefficient & Spearman's rho and multiple regression were used. Results: The higher the age of the subjects, the lower their educational background (r=-0.273, p<0.05), and the higher the probability of having a religion (r=-0.258, p<0.05), the more stable the employment type (r=-0.333, p<0.05). The higher the level of education, the higher the monthly income (r=0.187, p<0.01), and the shorter the career (r=-0.204, p<0.05). The more stable employment, the more unstable duty (r=-0.245, p<0.05), and the more unstable work, the higher the monthly income (r=-0.206, p<0.05) and the longer the career, the higher the monthly income (r=0.247, p<0.05). The more stable the employment, the more activities to improve physical function were found (r=0.341, p<0.05), and the more unstable the duty, the more activities to improve physical function were found (r=0.321, p<0.05), and the higher monthly income, the less physical function improvement activities (r=-0.196, p<0.05). Conclusions: It is necessary to provide regular services by a dedicated physical therapist for physical function improvement activities in order to improve the quality of life of the elderly in the future.
