Purpose: This study aimed to evaluate the validity and reliability of the Korean version of the Readiness for Practice Survey (K-RPS). Method: The English Readiness for Practice Survey was translated into Korean using the Translation, Review, Adjudication, Pretesting, and Documentation (TRAPD) method. Secondary data analysis was performed using the dataset from the New Nurse e-Cohort study (Panel 2020) in South Korea. This study used a nationally representative sample of 812 senior nursing students. Exploratory and confirmatory factor analyses were also conducted. Convergent validity within the items and discriminant validity between factors were assessed to evaluate con-struct validity. Construct validity for hypothesis testing was evaluated using convergent and discriminant validity. Ordinary α was used to assess reliability. Results: The K-RPS comprises 20 items examining four factors: clinical problem solving, learning experience, professional responsibilities, and professional preparation. Although the convergent validity of the items was successfully verified, discriminant validity between the factors was not. The K-RPS construct validity was verified using a bi-factor model (CMIN/DF 2.20, RMSEA .06, TLI .97, CFI .97, and PGFI .59). The K-RPS was significantly correlated with self-esteem (r = .43, p < .001) and anxiety about clinical practicum (r = - .50, p < .001). Internal consistency was reliable based on an ordinary α of .88. Conclusion The K-RPS is both valid and reliable and can be used as a standardized Korean version of the Readiness for Practice measurement tool.

Purpose: The purpose of this study is to understand the association between smoking status and adherence to physical activity (PA) guidelines among Korean adults, and the atherogenic index of plasma (AIP). Methods: The data from the Korea National Health and Nutrition Examination Survey from 2014 to 2021. When analyzing the effects of smoking and PA on the AIP, smoking status was classified as nonsmoker, former smoker, and current smoker. Meeting the PA guidelines was categorized as not meeting both the moderate-to-vigorous PA (MVPA) and muscle-strengthening activity (MSA) guidelines, meeting only the MVPA guidelines, meeting only the MSA guidelines, and meeting both. Logistic regression analysis was used to calculate the odds ratio (OR) and 95% confidence interval (CI) to determine the correlation between smoking status and AIP, whether PA guidelines were met and AIP, and the cross-effects. Results: The risk of AIP was about twice as high in current smokers (OR, 2.00; 95% CI, 1.87–2.14) compared to those who had never smoked. When conducting multiple logistic regression analysis using current smokers who met neither the MVPA nor MSA guidelines as the reference group, the risk of AIP was found to decrease in current smokers who met only the MSA guideline (OR, 0.84; 95% CI, 0.72–0.98) or both guidelines (OR, 0.66; 95% CI, 0.51–0.84). Conclusion For the prevention of cardiovascular diseases, it is important to engage in both aerobic and strength exercises that meet the PA guidelines, as well as to quit smoking. PA is thought to be able to buffer the effects of smoking.

Purpose: It is essential to ensure the readiness for practice among undergraduate nursing students since the purpose of such education is to cultivate competent nurses who deliver high-quality and safe nursing. Astin's theory of student involvement suggests that this is affected by their personal factors and learning environment. Methods: We conducted a cross-sectional study between November 16, 2020 and December 21, 2020 which examined personal factors and aspects of the clinical learning environment among senior nursing students (n = 838) enrolled across 54 nursing schools in Korea. The participants were asked to fill out a self-administered online survey, which assessed demographic characteristics, self-esteem, depression, work-life balance, clinical learning environment, anxiety during clinical practicum, and readiness for practice. Readiness for practice was measured using the Casey-Fink Readiness for practice survey. We used structural equational modeling to test our hypothetical model. Results: The nursing students' readiness for practice was significantly affected by their self-esteem, work-life balance satisfaction, and clinical learning environment. Anxiety during clinical practicum directly influenced their readiness for practice. Conclusion Increasing self-esteem and work-life balance satisfaction, and improving their clinical learning environment by providing sufficient educational and clinical support, could help facilitate the transition from nursing schools to real-world practice for nursing students.

Purpose: This study investigated the mediating effect of patient participation culture in the relationship between ethical leadership and performance in patient-engaged nursing services. Methods: This study employed a cross-sectional descriptive online survey design. The sample comprised 104 nurses from small- and middle-sized Korean hospitals.Data were collected between May 10 and September 10, 2019 using the Smart Patient Engagement Assessment Checklist, Korean versions of the Patient Participation Culture Tool for healthcare workers, the Ethical Leadership Scale, and a questionnaire about nurses' demographic and work characteristics. A mediation analysis was conducted using multiple regression and a simple model applying the PROCESS macro using SPSS/WINdows software version 26.0. Results: Ethical leadership directly affected (c'=0.28, p<.001) performance in patient-engaged nursing services. Patient participation culture partially mediated the relationship between ethical leadership and performance in patient-engaged nursing services (a ․ b=0.51×0.20=0.10, 95% Boot CI=0.18~0.20). Conclusion Optimizing the patient participation culture and adherence to ethical leadership among hospital administrators and managers can improve nurses' performance in patient-engaged nursing services. Nurse managers' ethical leadership should be strengthened, and patient participation culture should be encouraged at policy levels through systematic nurse education on patient safety and engagement to enhance performance-engaged nursing services.

BACKGROUND: To investigate the incidence of surgical intervention in very low birth weight (VLBW) infants and the impact of surgery on neurodevelopmental outcomes at corrected ages (CAs) of 18–24 months, using data from the Korean Neonatal Network (KNN). METHODS: Data from 7,885 VLBW infants who were born and registered with the KNN between 2013 to 2016 were analyzed in this study. The incidences of various surgical interventions and related morbidities were analyzed. Long-term neurodevelopmental outcomes at CAs of 18–24 months were compared between infants (born during 2013 to 2015, n = 3,777) with and without surgery. RESULTS: A total of 1,509 out of 7,885 (19.1%) infants received surgical interventions during neonatal intensive care unit (NICU) hospitalization. Surgical ligation of patent ductus arteriosus (n = 840) was most frequently performed, followed by laser therapy for retinopathy of prematurity and laparotomy due to intestinal perforation. Infants who underwent surgery had higher mortality rates and greater neurodevelopmental impairment than infants who did not undergo surgery (P value < 0.01, both). On multivariate analysis, single or multiple surgeries increased the risk of neurodevelopmental impairment compared to no surgery with adjusted odds ratios (ORs) of 1.6 with 95% confidence interval (CI) of 1.1–2.6 and 2.3 with 95% CI of 1.1–4.9. CONCLUSION: Approximately one fifth of VLBW infants underwent one or more surgical interventions during NICU hospitalization. The impact of surgical intervention on long-term neurodevelopmental outcomes was sustained over a follow-up of CA 18–24 months. Infants with multiple surgeries had an increased risk of neurodevelopmental impairment compared to infants with single surgeries or no surgeries after adjustment for possible confounders.

Background: The nature and role of the mitochondrial stress response in adipose tissue in relation to obesity are not yet known. To determine whether the mitochondrial unfolded protein response (UPRmt) in adipose tissue is associated with obesity in humans and rodents. Methods: Visceral adipose tissue (VAT) was obtained from 48 normoglycemic women who underwent surgery. Expression levels of mRNA and proteins were measured for mitochondrial chaperones, intrinsic proteases, and components of electron-transport chains. Furthermore, we systematically analyzed metabolic phenotypes with a large panel of isogenic BXD inbred mouse strains and Genotype-Tissue Expression (GTEx) data. Results: In VAT, expression of mitochondrial chaperones and intrinsic proteases localized in inner and outer mitochondrial membranes was not associated with body mass index (BMI), except for the Lon protease homolog, mitochondrial, and the corresponding gene LONP1, which showed high-level expression in the VAT of overweight or obese individuals. Expression of LONP1 in VAT positively correlated with BMI. Analysis of the GTEx database revealed that elevation of LONP1 expression is associated with enhancement of genes involved in glucose and lipid metabolism in VAT. Mice with higher Lonp1 expression in adipose tissue had better systemic glucose metabolism than mice with lower Lonp1 expression. Conclusion Expression of mitochondrial LONP1, which is involved in the mitochondrial quality control stress response, was elevated in the VAT of obese individuals. In a bioinformatics analysis, high LONP1 expression in VAT was associated with enhanced glucose and lipid metabolism.
