- Purpose
This study investigated the effects of a nursing leadership program on self-leadership, interpersonal relationships, clinical performance, problem-solving abilities, and nursing professionalism among nursing students in South Korea.
Methods
A quasi-experimental study was conducted. The Practice-Driven Nursing Leadership Program for Students (PDNLP-S) was developed based on the ADDIE model (analysis, design, development, implementation, and evaluation). This quasi-experimental study design included 60 nursing students. The experimental group (n=30) participated in the PDNLP-S for 120-minute sessions over 5 weeks, while the control group (n=30) received usual lectures. The PDNLP-S included lectures, discussions, and individual and group activities to cultivate core nursing leadership competencies such as individual growth, collaboration, nursing excellence, creative problem-solving, and influence. Data were analyzed using descriptive statistics, the Mann-Whitney U-test, and the independent t-test with IBM SPSS Windows ver. 26.0.
Results
The experimental group demonstrated significant improvements in self-leadership (t=3.28, p=.001), interpersonal relationships (t=3.07, p=.002), clinical performance (U=268.50, p=.004), and problem-solving abilities (t=2.20, p=.017) compared to the control group. No significant difference was observed in nursing professionalism (t=0.50, p=.311).
Conclusion
This study demonstrates that the PDNLP-S improved nursing students’ self-leadership, interpersonal relationships, clinical performance, and problem-solving abilities. The PDNLP-S can play a significant role in cultivating future nurse leaders by enhancing these nursing leadership competencies among nursing students.

Purpose
This study was conducted to evaluate the effect of breast milk olfactory stimulation on physiological responses, oral feeding progression, and body weight in preterm infants.
Methods
A repeated measures design with nonequivalent control group was used. The participants were healthy, preterm infants born at a gestational age of 28~32 weeks; 12 in the experimental group and 16 in the control group. Data were collected prospectively in the experimental group, and retrospectively in the control group, by the same methods. Breast milk olfactory stimulation was provided 12 times over 15 days. The data were analyzed using the chi-square test, Mann-Whitney U test, Wilcoxon signed rank test and linear mixed models using SPSS 19.
Results
The gastric residual volume (GRV) of the experimental group was significantly less than that of the control group. The heart rate, oxygen saturation, respiration rate, transition time to oral feeding, and body weight were not significantly different between the two groups.
Conclusion
These findings indicate that breast milk olfactory stimulation reduces GRV and improves digestive function in preterm infants without inducing distress.

- Purpose
This study explored the mediating role of organizational socialization in the relationship between social support and organizational commitment among nurses in hospitals who had experienced department rotation.
Methods
A descriptive survey design was used with 202 nurses from a tertiary hospital who had experienced department rotation within the past 12 months. Data were collected via an online questionnaire from August 1 to August 30, 2024. Analyses included frequency analysis, descriptive statistics, Pearson correlation, and multiple regression. The mediating effect was tested using IBM SPSS WIN ver. 23.0 and the PROCESS macro (model 4) with 10,000 bootstrap resamples.
Results
Organizational socialization partially mediated the relationship between social support and organizational commitment (B=.21; bootstrapped 95% confidence interval, 0.12–0.32).
Conclusion
The findings suggest that both social support and organizational socialization play essential roles in improving nurses’ organizational commitment following department rotation. Thus, practical programs, such as mentoring systems, should be implemented that both enhance social support and actively promote organizational socialization. These efforts have the potential to help nurses adjust more effectively to new units and ultimately improve retention and performance within healthcare organizations.
