Purpose: : This study aimed to identify the moderating and mediating effects of resilience on the relationship between role conflict and job satisfaction among nurses working in a comprehensive nursing care service ward. Methods: : Participants were 130 comprehensive nursing care service ward nurses from four hospitals. Data were collected using structured questionnaires and analyzed by t-test, ANOVA, Scheffé test, Pearson correlation coefficients, and hierarchical multiple regression analysis, using SPSS 25.0. The mediating effect of resilience on the relationship between role conflict and job satisfaction was analyzed using multiple regression analysis according to Baron and Kenny’s procedure. Results: : Statistically significant negative correlations were found between role conflict and resilience (r=-.25, p<.007) and between role conflict and job satisfaction (r=-.38, p<.001). A significant positive correlation was found between resilience and job satisfaction (r=.54, p<.001). A partial mediating effect of resilience was found between role conflict and job satisfaction (Z=-2.53, p=.012) but no moderating effect was found. Conclusion : To improve the job satisfaction of comprehensive nursing care service ward nurses, interventions for alleviating role conflict and improving resilience as well as evaluations of the two variables are necessary.

Background: Prevention of chronic diseases such as hypertension and diabetes is important, but few studies have identified barriers to healthy lifestyle practices among adults in their 30-50s. Therefore, this study is intended to be used as basic data for establishing a prevention and control strategy for chronic diseases. Methods: This study is a qualitative content analysis study using the focus group interview methodology. According to the inductive content analysis method, data were analyzed through the steps of ‘making sense of the data and whole’, ‘open coding’, ‘grouping’, ‘categorization’, and ‘abstraction’. Results: The categories of barriers to healthy lifestyle practice were derived as follows. ‘Low interest in health care’ in the intrapersonal domain, ‘absence of an assistant’ in the interpersonal domain, ‘organizational environment in which it is difficult to a healthy lifestyle practice’ in the organizational domain, ‘lack of infrastructure’ and ‘restrictions on use of public health centers’ in the community domain. Conclusions For the prevention and management of chronic diseases, adults in their 30-50s should be encouraged to take an interest in healthy lifestyle practices and increase their will. For healthy lifestyle practice, it is necessary to allow family members and friends to participate as helpers. In addition, at work, employers should pay attention to workers' health management, adjust working hours, and reduce the burden of company dinner to create an organizational environment for healthy lifestyle practice. Lastly, infrastructure such as public sports facilities should be additionally expanded, and the contents of public health centers' programs should be promoted.

OBJECTIVES: We estimated the population prevalence of antibodies to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), including unreported infections, through a Korea Seroprevalence Study of Monitoring of SARS-CoV-2 Antibody Retention and Transmission (K-SEROSMART) in 258 communities throughout Korea. METHODS: In August 2022, a survey was conducted among 10,000 household members aged 5 years and older, in households selected through two stage probability random sampling. During face-to-face household interviews, participants self-reported their health status, COVID-19 diagnosis and vaccination history, and general characteristics. Subsequently, participants visited a community health center or medical clinic for blood sampling. Blood samples were analyzed for the presence of antibodies to spike proteins (anti-S) and antibodies to nucleocapsid proteins (anti-N) SARS-CoV-2 proteins using an electrochemiluminescence immunoassay. To estimate the population prevalence, the PROC SURVEYMEANS statistical procedure was employed, with weighting to reflect demographic data from July 2022. RESULTS: In total, 9,945 individuals from 5,041 households were surveyed across 258 communities, representing all basic local governments in Korea. The overall population-adjusted prevalence rates of anti-S and anti-N were 97.6% and 57.1%, respectively. Since the Korea Disease Control and Prevention Agency has reported a cumulative incidence of confirmed cases of 37.8% through July 31, 2022, the proportion of unreported infections among all COVID-19 infection was suggested to be 33.9%. CONCLUSIONS The K-SEROSMART represents the first nationwide, community-based seroepidemiologic survey of COVID-19, confirming that most individuals possess antibodies to SARS-CoV-2 and that a significant number of unreported cases existed. Furthermore, this study lays the foundation for a surveillance system to continuously monitor transmission at the community level and the response to COVID-19.
