Purpose: This study aimed to review the intervention programs designed for married immigrant women living in Korea. Methods: A total of 39 articles published from 2010 to 2020 were selected and analyzed using domestic and international web-based academic databases according to a systematic literature review procedure. The selected studies were evaluated for quality according to RoB (Risk of Bias) and RoBANS (Risk of Bias for Non-randomized studies). Additionally, intervention programs and outcome variables were based on the Nursing Intervention Classification (NIC) and Nursing Outcome Classification (NOC) system. Results: According to the NIC categories, 69.2% of the interventions were in the behavioral domain, and 23.1% were in the family domain. The outcome variables primarily measured in NOC categories were psychological well-being (45.8%), health knowledge (11.0%), and health belief (10.2%). The quality of the selected studies was low overall in random sequence generation, allocation concealment, blinding of participants and personnel, and blinding of outcome data in randomized controlled trials (RCT) studies and confounding variables, blinding of outcome data, and incomplete outcome bias in non-RCT studies. Conclusion Based on the results of this study, future studies will have to consider the characteristics of the subjects, life cycle, daily life, or language limitations. In addition, it is necessary to develop high-quality programs through continuous research on currently and frequently used interventions and outcome variables and on other various mediations and to verify the outcome variables.

Purpose: The purpose of this study was to survey the Coronavirus Disease 2019 (COVID-19) related knowledge, risk perception, preventive behaviors, depression, and anxiety levels among nursing students, and to identify factors that influence preventive behaviors. Methods: An online survey was conducted among nursing students from October 7, 2020 to October 12, 2020. The data were analyzed using independent t-test, one-way ANOVA, Pearson’s correlation coefficients, and multiple regression. Results: A total of 222 nursing students participated in this study. The correct answer rate for COVID-19 knowledge was 90.0%, risk perception was 5.51 ± 1.26, and the rate for preventive behaviors was 92.5%. The depression score was 6.28 ± 4.63; 59.9% of nursing students had depression, and the anxiety score was 5.56 ± 3.98; 59.9% of nursing students had anxiety. COVID-19 preventive behaviors had a positive correlation with COVID-19 knowledge (r = .30, p < .001), COVID-19 risk perception (r = .18, p = .009), and anxiety (r = .21, p = .001).Factors influencing COVID-19 preventive behaviors by multiple regression were identified as COVID-19 knowledge, anxiety, physical health status before and after COVID-19, grade, practical experience after COVID-19, and COVID-19 risk perception (F = 12.46, p < .001, R 2 = 25.8%). Conclusion The results of this research on factors influencing COVID-19 prevention behaviors can be used in the future to develop appropriate health policies for individual and community infectious disease prevention behaviors.

Purpose: To identify factors influencing health-related quality of life for young single-person households, this study investigated physical and mental health status, health behavior, depression, resilience, and health-related quality of life. Methods: An online survey was administered to members of young single-person households from March 22 to 30, 2022. The data were analyzed using the chi-square test, independent t-test, one-way analysis of variance, Pearson correlation coefficients, multiple regression, and a simple mediation model applying the PROCESS macro model 4 with 95% bias-corrected bootstrapped confidence intervals. Results: The participants were 229 members of young single-person households. Health-related quality of life showed significant relationships with residence (t = 2.80, p = .006), monthly income (F = 3.70, p = .026), mental health status (F = 20.33, p < .001), and high-intensity exercise (F = 7.35, p = .001) among general and health-related characteristics. Health-related quality of life had significant correlations with depression (r = -.72, p < .001) and resilience (r = .58, p < .001). Multiple regression analysis showed that depression (β = -.57, p < .001) and resilience (β = .21, p < .001) influenced health-related quality of life. Moreover, resilience had a mediating effect between depression and health-related quality of life (indirect effect = -0.002, 95% bias-corrected bootstrapped confidence interval = -0.003 to -0.001). Conclusion Members of young single-person households tended to be more vulnerable to emergency situations, such as during the coronavirus disease 2019 pandemic, when lockdowns and quarantines were frequent. To improve health-related quality of life in young single-person households, people with high levels of depression or low levels of resilience need special attention and support to promote mental health.

PURPOSE: Span of Control defines the scope of the managers' responsibilities to manage nursing staff. This study was done to measure span of control of front-line nurse managers (FLNMs) in Korea hospitals resulting in improvement in their work efficiency. METHODS: A sample of 203 FLNMs from five tertiary hospitals was recruited and completed the questionnaires. Data were analyzed using χ²-test, Fisher's exact test, independent t-test, ANOVA, Scheffé, and Pearson correlation coefficient. RESULTS: FLNMs had ‘narrow’ (n=8, 4.3%), ‘appropriate’ (n=161, 87.0%), and ‘wide’ (n=16, 8.6%) span of control. Span of control had significant correlations with the number of nurses (r=.63, p<.001), the number of non-nurses (r=.53, p<.001), units (r=.52, p<.001), staff (r=.83, p<.001), and programs (r=.67, p<.001). CONCLUSION: The research findings indicate that attention should be given to unit complexity, program diversity, total staff, and skills. Moreover, administrators of hospital and nursing departments need to provide systematic support in accordance with FLNMs’ wide span of control.

PURPOSE: This integrative review study was done to analyze methods used for validation studies in Korean nursing research. METHODS: In this study, the literature on instrument development in nursing research from Research Information Sharing Service (RISS) and major nursing journal databases in Korea were examined. The MeSH search terms included 'nursing', 'instrument', 'instrument development', 'validation' and 189 articles were included in the review. RESULTS: The most frequently reported validity type was content validity, followed by construct validity, and criterion validity. One third reported a single type of validity, and 15% of the studies demonstrated three kinds of validity at the same time. In about 40% of the studies, both content and construct validity were examined. CONCLUSION: The results of the study indicate that it is necessary to provide a wider variety of evidence to establish whether instruments are valid enough to use in nursing research.

PURPOSE: To summarize and review the methodological quality of the evidence from trials examining the effectiveness of physical exercise in patients undergoing allogeneic hematopoietic stem cell transplantation (Allo-HSCT). METHODS: Six randomized clinical trials (RCTs) were identified, reviewed for substantive results, and assessed for methodological quality. RESULTS: Six trials met all methodological criteria on the modified Jadad score above 3 out of 5 points. Failure to blind the outcome assessor, and failure to describe the method of blinding of outcome assessor appropriately were the most prevalent methodological shortcomings. Various exercise modalities have been applied, differing in content, frequency, intensity, and duration. Positive results have been observed in part for a diverse set of outcomes, including physical and psychological performance. CONCLUSION: The trials reviewed in this study were of moderate methodological quality. They suggest that exercise in patients undergoing Allo-HSCT may be safe and feasible, and in part patients benefit from increased physical performance both during and after transplantation. Future RCTs should use larger samples, appropriate comparison groups, and a standard of outcome measures, and examine what kind of exercise intervention (aerobic vs. resistance vs. combined) is the most effective for Allo-HSCT patients. It would be necessary to define contraindication for exercise to guarantee its safety.

Purpose: This study was designed to verify whether shear-wave elastography (SWE) can be used to differentiate ulnar neuropathy at the cubital tunnel from asymptomatic ulnar nerve or medial epicondylitis. An additional aim was to determine a cut-off value to identify patients with ulnar neuropathy. Methods: This study included 10 patients with ulnar neuropathy at the cubital tunnel as confirmed with electromyography (three women and seven men; mean age, 51.9 years), 10 patients with medial epicondylitis (nine women and one man; mean age, 56.1 years), and 37 patients with asymptomatic ulnar nerve and lateral epicondylitis (21 women and 16 men; mean age, 54.0 years). Each patient underwent SWE of the ulnar nerve at the cubital tunnel, distal upper arm, and proximal forearm. Results: Patients with ulnar neuropathy at the cubital tunnel exhibited significantly greater mean ulnar nerve stiffness at the cubital tunnel (66.8 kPa) than controls with medial epicondylitis (21.2 kPa, P=0.015) or lateral epicondylitis (33.9 kPa, P=0.040). No significant differences were observed between patients and controls with regard to ulnar nerve stiffness at the distal upper arm or the proximal forearm. A stiffness of 31.0 kPa provided 100% specificity, 80.0% sensitivity, 100% positive predictive value, and 83.3% negative predictive value for the differentiation between ulnar neuropathy and medial epicondylitis. Conclusion Cubital tunnel syndrome is associated with a stiffer ulnar nerve than lateral or medial epicondylitis. SWE seems to be a new, reliable, and simple quantitative diagnostic technique to aid in the precise diagnosis of ulnar neuropathy at the cubital tunnel.

Background: Low-density lipoprotein (LDL) cholesterol is a strong predictor of cardiovascular disease, resulting in the promotion of low-fat diets that emphasize the need to lower LDL cholesterol levels. We investigated the relationship between dietary carbohydrate intake and cardiovascular risk factors according to LDL cholesterol levels in Korean adults who typically consumed high-carbohydrate, low-fat diets. Methods: A total of 25,925 Korean adults were selected from the 2007-2015 Korea National Health and Nutrition Examination Surveys. Dietary carbohydrate intake was grouped into quintiles and cardiovascular risk factors included obesity, metabolic syndrome, type 2 diabetes, and dyslipidemia. Multiple logistic regression models were used to examine association between carbohydrate intake and cardiovascular risk factors by sex and LDL cholesterol levels. Results: Subjects with LDL cholesterol ≥130 mg/dL had significantly less energy and fat intake than those with LDL cholesterol <130 mg/dL both in men and women. In men, a higher carbohydrate intake was related to increased prevalence of atherogenic dyslipidemia and low high-density lipoprotein (HDL) cholesterol regardless of LDL cholesterol levels. Meanwhile, dietary carbohydrate intake was positively associated with low HDL cholesterol but inversely associated with hypercholesterolemia only in women with LDL cholesterol <130 mg/dL. Conclusions High carbohydrate intake in Korean adults is associated with low HDL cholesterol or atherogenic dyslipidemia regardless of LDL cholesterol levels. Carbohydrate intake should be carefully recommended according to the lipid profiles of individuals for the prevention and management of cardiovascular disease.
