Korean Elderly

This study was conducted to identify the factors associated with frailty according to gender of older adults living alone in Korea. Data from the National Survey of the Living Conditions of Korean Elderly in 2017 were used. Participants were 2340 older adults who live alone. Frailty was determined based on the frailty criteria developed by van Kan et al. that consist of fatigue, resistance, ambulation, and illness. The collected data were analyzed using descriptive statistics, chi-squared test, t-test, Jonckheere–Terpstra test and multinomial logistic regression. Among the older men living alone, 47.7% were in the pre-frail and 5.1% were in the frail. On the other hand, 51.8% were in the pre-frail and 12.2% were in the frail among the older women living alone. The factors associated with frailty according to gender are as follows. In males, depressive symptoms, limitation in IADL, and number of medications in pre-frail; BMI, limitation in IADL, and number of chronic diseases in frail. In females, depressive symptoms, number of chronic diseases, age, and nutritional status in pre-frail; limitation in IADL, depressive symptoms, age, number of chronic diseases, number of medications, nutritional status in frail. Based on the findings of this study, it is considered necessary to approach frailty management considering gender as well as the classification of frailty.

Today, innovation is achieved by challenging the existing paradigm through cross-field collaboration, and R&D innovation plays a particularly crucial role. This study analyzed the effects of R&D innovation activities on business management performance in South Korea and examined the role that patents play in various R&D innovation activities. Panel regression and moderating effect analyses were conducted on small- and medium-sized venture enterprises that undertook new technology projects over five years (2015–2019). The results showed that R&D innovation activities had a significantly positive effect on both revenue, an indicator of business growth, and operating profit, an indicator of profitability. This implies that such activities play a positive role in management activities. Thus, enterprises should consider R&D innovation activities from a business growth strategy perspective. Additionally, the analysis showed that a firm’s capacity to hold patents on R&D innovation activities has a positive moderating effect on business management performance. This study is significant, as it reveals the cause-and-effect relationship between R&D innovation actives and business management performance as well as the role of various types of innovation. The results could help enterprises to seamlessly implement innovation activities in the future.

The Relationship

Abstract Background Understanding how living arrangements may affect psychological well-being (PWB) is critical in China, a society with the largest older population in the world. However, few studies have examined the moderating effect of income sources on the relationship between living arrangements and PWB. Our aim was to examine whether living arrangements are associated with PWB and whether income sources moderate this association. Methods The data were drawn from the third (2002) to sixth (2011/2012) waves of the Chinese Longitudinal Healthy Longevity Survey (CLHLS). Six questions reflecting older adults’ well-being were used to measure PWB. Living arrangements were classified as follows: living alone, living with family and living in an institution. Income sources were categorized into financially independent, supported by children, and governmental support. We performed random-effects ordinal probit models to examine the association of living arrangements with PWB and the moderating effect of income sources on this relationship. Results We included a total sample of 30,899 observations for 16,020 respondents aged 65 and over during 9-year follow-up. Older adults living with family (β = .29, p < .001) and those living in an institution (β = .34, p < .001) had stronger PWB than those living alone; moreover, support from children (β= −.24, p < .001) or from the government (β= −.08, p < .05) has a negative effect on PWB compared to the effect of financial self-support. Living in an institution with support from children (β= −.22, p < .05) led to lower PWB than living alone with financial self-support. The opposite result was observed for older adults living with their family and supported by the government (β = .16, p < .05). Conclusions Our analysis provides a significant contribution to the existing literature on the relationship between living arrangements and PWB in China. We recognize that living with family or in an institution leads to better PWB than does living alone. In addition, financial support from the government can moderate this association.
