Abstract PDF: Purpose
Preventing the effects of physical vulnerability is a practical approach to improving older adults’ depressive symptoms. This study aims to examine the relationship between gender differences related to muscle strength and depressive symptoms mediated by perceived stress.
Methods
In this cross-sectional study, data from 2,705 older adults (65 years old or older) from the Korea National Health and Nutrition Examination Survey VII 2016 and 2018 were analyzed. The moderated mediation model was developed; the outcome, independent, mediation, and moderated mediation variables in the literature-based research model were depressive symptoms, muscle strength, perceived stress, and gender, respectively.
Results
Perceived stress had a mediating effect on the relationship between muscle strength and depressive symptoms. The indirect effect of muscle strength on depressive symptoms mediated by perceived stress was β = -.02 (95% CI:-0.03~-0.01). The moderated mediation model demonstrated that the interaction term of handgrip strength and gender negatively affected perceived stress, which indicated that gender moderated the mediating model of perceived stress on the association of muscle strength and depressive symptoms (β = -.01, p <.05). The conditional indirect effect model was insignificant in the male group (β = -.00, 95% CI:-0.01~0.01) but significant in the female group (β = -.01, 95% CI: -0.02~0.00). Conclusions: Perceived stress mediated the relationship between muscle strength and depressive symptoms. However, the effect differed by gender. A stress-mediated depressive symptoms intervention program for older adults should be developed to consider women’s needs.

Abstract PDF: Purpose
This study aimed to identify the effects of fatigue and emotional labor on the quality of sleep among apartment security guards.
Methods
A total of 196 apartment security guards working in 10 different regions participated in the study between July and October 2022, completing questionnaire assessing fatigue (physical imbalance, exhaustion, mental fatigue, and nervous system disfunction), emotional labor, and sleep quality. Data were analyzed using descriptive statistics, independent t-test, Mann-Whitney U test, ANOVA including Scheffe’s post hoc, and regression analysis.
Results
183(93.4%) participants were poor sleeper. Regression analysis of the factors influencing sleep quality yielded a significant model (F= 21.56, p<.001) with an explanatory power of 25.0% in the order of fatigue(exhaustion) (β=.28, p<.001), emotional labor (β=.27, p<.001), and subjective economic status (β=.15, p=.017).
Conclusion
It is essential to develop nursing educational programs that reduce exhaustion and emotional labor for improving the quality of sleep.

Abstract PDF: Purpose
This study verified that the dual sensory impairment (DSI) in the elderly is associated with cognitive impairment (CI) and confirmed how change in cognitive function varies depending on the social support (SS).
Methods
For a study sample of Korean older people, data from the Korean Longitudinal Study of Ageing (KLoSA) from the 7th (2018) to the 8th (2020), were included in this cross-sectional descriptive study. Among people who responded in both 2018 and 2020, a total of 2,069 people of those who are 65 years of age or older, and have living children and normal cognitive function, were analyzed. X2 -test, t-test and logistic regression analyses were utilized.
Results
First, the number of elderly with visual impairment (VI), hearing impairment, and DSI increased on 8th data compared with 7th data. In addition, 22.9% of the 2,069 people showed a decrease in cognitive function. Second, compared to the elderly with normal sensory function, the cognitive function of the elderly with only VI was found to be more degraded, and the cognitive function of the elderly with DSI was found to be much more degraded. In addition, among SS, only participation in social gatherings was found to show significant change in cognitive function of the elderly with DSI. Third, the interaction effect of participating in social gatherings was not significant in the CI of the elderly with DSI.
Conclusion
VI and DSI effected cognitive function, but participation in social gatherings such as SS has not significant interaction effect on CI of the elderly with DSI.

Abstract PDF: Purpose
Over time, the number of migrant workers in Korea has shown a steady increase. Notably, among all migrant workers, those from Vietnam constitute the third largest group in Korea. The main objective of this study was to investigate the factors that influence the health-related quality of life of Vietnamese migrant workers. The study aimed to provide essential data for the development of customized nursing intervention programs and policy preparation in the future.
Methods
A total of 220 Vietnamese migrant workers aged between 18 and 64, who were employed in Korea through the Employment Permit System and had been residing in the country for more than 91 days, participated in this study.
Results
The study results revealed that physical activity (β=.19, p=.002), hope (β=.50, p <. 001), cohabitation with colleagues (β=.16, p =.003), and sleep hour (β=.11, p =. 031) had a statistically significant impact on health-related quality of life. The findings showed that higher levels of physical activity and hope were positively associated with higher health-related quality of life. Moreover, cohabiting with colleagues and sleeping for more than six hours were also significantly related to higher health-related quality of life.
Conclusion
Given these findings, it is imperative to develop programs that encourage physical activity and enhance the health-related quality of life of migrant workers from Vietnam. Policymakers and employers should also consider providing adequate living conditions that facilitate cohabitation with colleagues and sufficient time for sleep to improve the health and well-being of migrant workers.

Abstract PDF: Purpose
This study aims to find out further about the burden on families in undertaking caregiving for the elderly with chronic illnesses.
Methods
A qualitative study was developed using in-depth interviews with 12 family caregivers selected by purposive sampling in July 2022. The thematic analysis was then carried out using the Colaizzi method, and N-Vivo 12 Qualitative Data Analysis Software was used to assist with the content analysis.
Results
The result from the experience interview analysis of caregivers participating in this study were 54 codes which were categorized into thirteen categories. Then, they were derived into four themes, as follows: 1) Physical burden of the caregivers for the elderly with chronic illness, 2) Psychological burden of the caregivers for the elderly with chronic illness, 3) Obstacle of caregivers for the elderly with chronic illness, 4) The state of caregivers who perform caregiving for the elderly with chronic illness.
Conclusion
The experience of caregivers in undertaking caregiving for the elderly with chronic disease has many obstacles, such as physical, psychological, and economic burdens. Caregivers often find positive aspects of their experiences while caregiving for the elderly, although their burden also constantly increases. Health facilities should pay serious attention to family caregivers and facilitate programs that can help reduce the burden on family caregivers.

Abstract PDF: Purpose
This study aimed to determine the effects of gestational diabetes mellitus, breastfeeding-related pain, and infant growth on the cessation of breastfeeding. Methods: This is secondary data analysis. This study included 60 pregnant women from 3 prenatal breastfeeding clinics. Pregnant women aged 20–49 years, with or without a diagnosis of gestational diabetes mellitus were enrolled. The participants were administered four self-reported questionnaires, one at 5 days, 14 days, 3 months, and 6 months postpartum. A linear mixed model and Cox regression analysis were used. Data were collected between May 25, 2020 and June 14, 2021. Results: The rate of breastfeeding cessation was 55.0% (n=33). The average maternal ages were 32.30 (±4.61) and 31.33 (±7.05) years in the cessation and maintenance groups, respectively. The average duration of breastfeeding in the cessation group was 56.27 (±37.48) days. After adjusting for all covariates, the risk of breastfeeding cessation was 2.5 times greater among participants diagnosed with gestational diabetes mellitus (p=.042). Additionally, the risk of breastfeeding cessation was 1.3 times greater among those with severe breastfeeding-related pain (p=.015). Conclusion: The first two months postpartum is the most essential time for healthcare workers to provide support and address difficulties associated with breastfeeding for mothers with gestational diabetes mellitus.
