PURPOSE: The purpose of this study was to examine differences in the prevalence of vitamin D deficiency between male and female Korean adolescents and to investigate gender-specific factors associated with vitamin D deficiency. METHODS: This cross-sectional descriptive study included 975 adolescents aged 12-18 years who participated in the fifth Korean National Health and Nutrition Examination Survey (2010~2011). Multiple logistic regression using complex sample analysis was performed to examine gender-specific factors associated with vitamin D deficiency with adjustments for covariates. RESULTS: Among the participants, 82.9% had vitamin D deficiency. The prevalence of vitamin D deficiency was higher among female adolescents (88.4%) than their male counterparts (78.4%). A rural place of residence (OR, 0.40; 95% CI, 0.19~0.87; p=.021) and daily milk intake (OR, 0.23; 95% CI, 0.07~0.75; p=.015) were significant factors significantly associated with vitamin D deficiency in males, while body mass index (OR, 8.40; 95% CI, 1.05~67.04, p=.045) and having breakfast (OR, 0.22; 95% CI, 0.10~0.49; p < .001) showed significant relationships in females. CONCLUSION: The results of this study provide preliminary evidence for developing effective strategies to prevent vitamin D deficiency in Korean adolescents. The different factors influencing vitamin D deficiency in males and females should be considered when providing interventions.

Purpose: This study examined the relationships between organizational silence, organizational commitment, organizational justice, and organizational citizenship behavior among clinical nurses. Additionally, it determined the mediating effect of organizational commitment moderated by organizational justice on the relationship between organizational silence and organizational citizenship behavior among clinical nurses. Methods: A total of 160 clinical nurses were recruited from a university hospital. Data were collected from June to July, 2023. The collected data were analyzed using descriptive statistics, independent t-test, one-way ANOVA, Scheffé test, Pearson’s correlation coefficient, Baron and Kenny’s three-step regression analysis, Hayes’ PROCESS macro model, and bootstrapping using SPSS/WIN 27.0 program. Results: Organizational commitment had a full mediating effect on the relationship between organizational silence and organizational citizenship behavior (B=-0.04, CI [-0.098~-0.001]). Among the subscales of organizational justice, distributive justice had a moderating effect on the relationship between organizational silence and organizational commitment (B=-0.17, p=.009). There was no significant mediating effect of organizational commitment moderated by organizational justice on the relationship between organizational silence and organizational citizenship behavior. Conclusion Appropriate strategies are needed to effectively manage nursing personnel and improve nursing performance.

Purpose: This study aimed to confirm the mediating effects of transition shock on the relationships among grit, social support, and retention intention of new graduate nurses. Methods: A total of 174 new graduate nurses were recruited from a university hospital and a general hospital. The data were collected between November and December 2022 and analyzed using descriptive statistics, independent t-test, one-way analysis of variance, Scheffé test, Pearson’s correlation coefficient, Baron and Kenny’s three-step regression analysis, and the PROCESS Macro Model 4. Results: Nurses’ retention intention was positively correlated with grit (r=.56, p<.001) and social support (r=.48, p<.001) and negatively correlated with transition shock (r=-.56, p<.001). The mediating analysis revealed that transition shock mediated the relationship between grit and retention intention as well as between social support and retention intention. Conclusion Based on the findings, an intervention program should be developed to reduce transition shock in new graduate nurses to increase their intention of retention.

OBJECTIVES: This study aimed to identify and systematically review the literature on the use of mobile technology in nursing education. The research findings could evidence the effectiveness of mobile technology in undergraduate nursing students' learning outcomes. METHODS: Computerized searches were conducted using the Ovid-MEDLINE, Ovid-EMBASE, Cochrane Library, and CINAHL databases for relevant primary studies and limited to those between 2000 and February 2018. Only randomized controlled trials (RCTs) and quasi-experimental studies published in either English or Korean were included and critically appraised using Joanna Briggs Institute tools. RESULTS: Seven RCTs and 7 quasi-experimental studies were identified. The mobile device and intervention applied varied throughout all the studies. Studies published earlier in the 2000s found that immediate access to clinical and pharmacological referencing information through the mobile device increased students' efficacy in clinical practice. Later studies, which were mostly conducted in Korea, reported that smartphone-based applications could promote nursing students' learning motivation and satisfaction but not their clinical skills and knowledge. CONCLUSIONS: We still seem to be in the beginning stage of implementing mobile technology in nursing education due to the limited implication of mobile technology and inconsistent research conclusions. In the future, rigorous primary empirical studies are needed to suggest the effective use of mobile devices in nursing education.
