Objectives: Previous studies have found that the oral health of seniors can affect their physical nutrition and quality of life (QoL). Additionally, poor oral health can lead to the development of dementia, which is associated with decreased cognitive function. This study aimed to examine the impact of geriatric oral health (GOH) on the QoL of Korean seniors and the mediating effects of cognitive function. Methods: We used data from the seventh Korean Longitudinal Study of Aging conducted in 2018. In total, 4049 seniors were included in our study. We analyzed the impact of GOH on QoL according to 5 mediating domains of cognitive function and control variables. To examine each path of mediating effects, bootstrapping with 5000 iterations was performed with 95% confidence intervals. Results: Our findings revealed that good GOH had a positive effect on the QoL of seniors. Also, better GOH corresponded to a higher degree of cognitive function within all 5 domains: orientation, memory registration, attention/calculation, memory recall, and language and visuospatial ability. In addition, 3 domains of the 5 domains (attention/calculation, memory recall, and language and visuospatial ability) had significant mediating effects on the relationship between GOH and QoL. Conclusions: This study suggests that adequate management of GOH is crucial for promoting a better QoL and a high degree of cognitive function among seniors. To prevent cognitive impairment, such as dementia, future studies should take a more targeted approach by examining data according to each cognitive domain and various socio-demographic factors.

Objectives: The aim of this study was to analyze the relationship between objective social isolation (SI) and unmet medical needs (UMN) in adults aged 19 and older. Methods: A cross-sectional analysis was conducted of 208 619 adults aged 19 and older, excluding missing data, using the 2019 Korea Community Health Survey. To analyze the association between objective SI and UMN, the chi-square test and logistic regression analysis were performed. Results: The prevalence of UMN was 1.14 times higher (odds ratio [OR], 1.14; 95% confidence interval [CI], 1.06 to 1.23) among those with SI than among those without SI, and the OR for groups with 5 SI types was 2.77 (95% CI, 1.86 to 4.12) compared to those with no SI types. In addition, a stratified analysis by age group showed that the association between SI and UMN existed even in groups under 64 years old. However, among those aged 65 and older, SI was associated with an OR of 1.53 (95% CI, 1.37 to 1.71) for UMN compared to non-SI. As the number of SI types increased, the prevalence of UMN also increased, indicating a strong association between SI and UMN in older adults. Conclusions: This study found that individuals with SI experienced UMN due to fear and anxiety about interpersonal relationships. Therefore, based on the results of this cross-sectional study, it is necessary to investigate the causal relationship between SI and UMN through future longitudinal data.

Objectives: The purpose of this study was to identify the effects of job characteristics on smoking, and the mediating effects of job stress between job characteristics and smoking among elderly workers. Methods: This study employed data from the Korean Longitudinal Study of Ageing, and a total of 778 older workers were used for analysis. Current smoking status, job stress, job characteristics including physical job demands, job demands related to contents, working days, regularity of working hour, satisfaction with income, and sociodemographic factors were analyzed. Descriptive analysis, t-tests, chi-square test, multiple linear regression, and logistic regression were used for analysis. Results: Results showed that physical job demands and regularity of working hours were significant predictors of smoking of elderly workers. The higher level of physical job demands and regular working-hour increased the risk of smoking. Also, physical job demands, job demands related job contents, and income satisfaction directly impacted on job stress. However, job stress did not mediate the relationship between job characteristics and smoking. Conclusions: The findings suggest that smoking interventions for older workers should take into account job characteristics. Implications for practice and future study directions are discussed.

Objectives : This study was conducted to examine social factors associated with problematic drinking among middle- and older-aged men in South Korea. Methods : The data were collected from the baseline survey of the Korean Longitudinal Study of Aging, and the sample consisted of 3,631 men between 45 and 64 years of age and 1,173 men aged 65 or older. This study employed variables identifying various socioeconomic features, social ties, and health-related factors. Logistic regressions were used for the data analysis. Results : Middle-aged men having frequent social relationship with close persons were significantly more likely to be problematic drinkers than those having less frequent social relationships with close persons. Lower education, unemployment, smoking, and depression were associated with problematic drinking only among middle-aged men. Conclusions : We suggest that health professionals develop specific intervention strategies that could lead to more moderate alcohol habits and better health in middle aged Korean men who are actively engaged in social networks. In addition, health professionals need to focus more on the unemployed, lower educated, depressed, and smoking groups for early detection of problematic drinking among middle-aged Korean men.

Purpose: This study was done to test a structural equation modeling of case management outcomes in order to identify parameters affecting case management outcomes for the community-dwelling vulnerable elders. Methods: Data were collected from 309 nurses (case managers) and community-dwelling vulnerable elders (clients) from public health centers. For data analysis, descriptive statistics, Pearson correlation analysis, factor analysis, and covariance structure analysis were performed using SPSS Version 18.0 for Windows and Amos 16.0. Results: The hypothetical model had an acceptable fit: GFI=.97, CFI=.95, RMSEA=.02, SRMR=.05. The factor "case managers' singularity" had the greatest impact on case management outcomes in this model. In addition, the factor "case management practice" influenced case management outcomes; however, client characteristics did not. Case managers' singularity affected case management outcomes directly and indirectly, with case management practice mediating the latter effect. Conclusion: These results suggest that the causal relationship between case management outcomes and factors influencing these outcomes should be clarified through longitudinal research including a variety of client characteristics. In addition, in future studies, analysis of the effects of programs to improve manpower quality and examine the relationships among case management outcomes should be done.

Purpose: The purpose of this study was to construct and test a structural equation modeling on burnout of clinical nurses based on CS-CF model. Methods: A survey using a structured questionnaire was conducted with 557 clinical nurses. Data were analyzed using structural equation modeling. Results: The modified hypothetical model yielded the following ${\chi}^2=289.70$, p<.001, RMSEA=.09, GFI=.93, TLI=.91, CFI=.94, PCFI=.65, AIC=363.21, SRMR=.05 or less and showed good fit indices. Nursing work environment, patient safety culture and resilience showed indirect effects on burnout while compassion fatigue and compassion satisfaction had direct effects. Conclusion: Results of this study suggest that compassion fatigue must be decreased and compassion satisfaction has to be increased, while burnout is lowered by enhancing the clinical nursing work environment, patient safety culture and resilience. In addition, more variables and longitudinal studies are necessary to validate the clear cause-and-effect relationship between the relevant variables.

Purpose: This study was conducted to identify activities of daily living, depression and self-rated health and related factors for Korean Elderly. Methods: Data from the survey for the Korean Longitudinal Study of Aging in 2010 were used. The data were analyzed using frequencies, weighted proportions, and hierarchical multiple logistic regression. Results: Significant difference was observed in health status induced by socioeconomic status between men and women, but not among age groups. Socioeconomic status was strongly associated with self-rated health among male and female elders. Being unschooled and low net family asset were significantly related with dependency in activities of daily living and depressive symptoms among men. Only low net family asset was significantly related with depressive symptoms among women. Family support provides a slight decrease to the negative relationship between socioeconomic status and health status, especially depressive symptoms. Conclusion: This study suggests that interventions to reduce health inequalities should target elderly with lower socioeconomic status and with poor family support, using a gender-specific approach.

The socket-spigot template supporting system is widely used in engineering applications in China. As a newer type of support structure, there has been growing research interest in its bearing capacity. In this paper, four vertical bearing capacity tests were carried out on the basic mechanical unit frame of a socket-spigot template supporting system. The first goal was to explore the influence of the node semi-rigid degree and the longitudinal spacing of the upright tube on the vertical bearing capacity. The second objective was to analyze the displacement trend and the failure mode during the loading process. This paper presents numerical analysis of the vertical bearing capacity of the unit frames using the finite element software ANSYS. It revealed the relationship between the node semi-rigid degree and the vertical bearing capacity, that the two-linear reinforcement model of elastic-plastic material can be used to analyze the socket-spigot template supporting system, and, through node entity model analysis, that the load transfer direction greatly influences the node bearing area. Finally, this paper indicates the results of on-site application performance experiments, shows that the supporting system has adequate bearing capacity and stability, and comments on the common work performance of a socket and fastener scaffold.

Objective: The purposes of this study are to test a direct effect of mother-child interaction and to examine the mediating effect of children's smart media use on a child's sleeping hours. Methods: We analyzed the longitudinal data of 1,494 children from the $6^{th}$ panel study of Korean children collected by the Korea Institute of Child Care and Education in 2013, which examined 5-year-old children. The main analysis method was Structural Equation Modeling (SEM). Results: The study results showed that mother-child interaction had a direct effect on the child's sleeping hours. Children's smart media use also directly influenced the child's sleeping hours. In regard to mediation, the results revealed that children's smart media use mediated the relationship between mother-child interaction and child's sleeping hours. Conclusion/Implications: Bidirectional mother-child interaction and the degree of smart media use played an important role in children's sleeping hours. This study suggests policy and practical implications in order to retain children's healthy sleeping hours.
