Purpose : This study aimed to develop a Nursing Education Mobile Application (NEMA) to enable shift-working nurses to engage in self-directed learning without temporal and spatial constraints, and to verify its effects on confidence in core nursing skill performance and learning satisfaction. Methods : A randomized controlled pre–post tests design was used with 64 shift nurses from a tertiary hospital in Seoul, Korea (34 experimental, 30 control). The experimental group used the NEMA app for six weeks, while the control group studied written educational material. The data were analyzed using t-tests. Results : After self-learning with the app, the experimental group scores increased by an average of 0.58 points in confidence in core nursing skill performance, compared with 0.21 points in the control group. This difference was significant (t=2.35, p=.022). Learning satisfaction also increased more significantly in the experimental group (0.54 points) than in the control group (0.10 points) (t=2.37, p=.021). Conclusion : NEMA significantly improved confidence in core nursing skill performance and learning satisfaction among shift-working nurses. Mobile-based education, with its anytime–anywhere accessibility and self-directed learning features, can effectively supplement traditional methods. Further studies should examine its application in diverse settings and long-term effects on clinical performance.

Purpose : This study aimed to examine the prevalence of workplace bullying experienced by clinical nurses. Methods : A total of 221 clinical nurses employed at general hospitals across South Korea participated in a structured online survey. The data were analyzed using SPSS 24.0, applying descriptive statistics, t-tests, and ANOVA. Results : The most frequently used coping strategies by nurses were avoidance (M=2.91/4), seeking advice from peers (M=2.92/4), and non-response or focusing on work as if nothing happened (M=2.89/4). In contrast, formal or assertive coping behaviors such as reporting incidents or confronting perpetrators were scored significantly low. The perceived managerial response to workplace bullying was also low (M=2.37/4), indicating a passive and insufficient intervention pattern. Conclusion : These results reflect persistent hierarchical organizational culture and structural limitations in institutional responses within nursing environment. Suggestions are the urgent need to strengthen the practical enforceability of workplace bullying regulations, fostering a horizontal and psychologically safe organizational culture, and enhancing leadership competency among nurse managers for effective conflict resolution and protection of nursing staff.

Purpose : This study aimed to examine the three-year (2022~2024) period in job stress among workers in a manufacturing company and to identify factors influencing these changes using a linear mixed model. Methods : The study participants were 597 workers whose job stress was assessed annually from 2022 to 2024. Job stress was measured using the Korean Occupational Stress Scale (KOSS). The data were analyzed with SPSS version 25.0, applying linear mixed modeling to account for repeated measures. Results : Job stress did not show a significant change over time. However, significant predicting factors of changes in job stress included gender, age, work experience, and employment type. Conclusion : When developing and implementing workplace interventions to manage job stress among industrial workers, demographic characteristics (i.e., gender, age) and occupational factors (i.e., work experience, employment type) identified as significant factors of job stress should carefully be considered. The study is noteworthy in that it examined longitudinal trends and influencing factors of job stress over a three-year period.

Purpose : This study aimed to identify the factors influencing wellness in school foodservice workers and to provide meaningful information for developing intervention programs to improve their wellness. Methods : The participants were 170 school foodservice workers employed at 20 elementary, middle and high schools. Dietitians, whose job characteristics differ from foodservice workers, and part-time workers were excluded. The data were collected using a structured questionnaire between August and October, 2024. The data analysis including multiple regression was performed. Results : Multiple regression analysis identified subjective happiness (β=.43, p<.001) and fatigue (β=-.17, p=.018) as significant factors influencing wellness in school foodservice workers. Lower fatigue and higher subjective happiness were associated with higher wellness. These variables explained 25.6% of the variance in wellness. Conclusion : Based on our findings, customized workplace wellness programs should focus on increasing happiness and reducing fatigue to enhance their wellness.

Purpose : This study aimed to examine the effects of self-efficacy and perceived preceptors’ clinical teaching behavior on the organizational socialization of recently graduated nurses. Methods : The participants were 138 recently graduated nurses who had been employed at two tertiary hospitals for 12 months or less. The data were collected using structured self-reported questionnaires from July 23 to August 31, 2024. T-tests, one-way analysis of variance, Shapiro-Wilk test, Welch test, Scheffé's test, Pearson's correlation analysis, and multiple regression analysis were conducted to analyze the data. Results : Organizational socialization showed significant differences depending on the work department and gender. Organizational socialization was significantly correlated positively with self-efficacy (p<.001) and preceptors’ clinical teaching behavior (p<.001). Significant predictors of organizational socialization among recently graduated nurses were self-efficacy (β=.45, p<.001), preceptors’ clinical teaching behavior (β=.27, p<.001), and gender (β=-.15, p=.027). These variables accounted for 41% of the variance in recently graduated nurses' organizational socialization (F=31.32, p<.001). Conclusion : The results of this study showed that considering self-efficacy and preceptors’ clinical teaching behavior might be helpful for developing strategies to enhance organizational socialization among recently graduated nurses.

Purpose : This descriptive correlation study explored the moderating effects of supervisor’s support, coworker’s support and family’s support on the relationship between emotional labor and job stress of department store sales workers. Methods : The data were collected from 147 employees with at least one month of sales experience at an L department store located in S city. The data were analyzed using descriptive statistics, independent t-test, ANOVA analysis of variance, Pearson’s correlation coefficient, and multiple regression with the SPSS/WIN 29.0 program. Results : Emotional labor showed a significant positive correlation with job stress(r=.46, p<.001). Supervisor’s support(β=.78, p<.001) and coworker’s support(β=.67, p=.005) were found to moderate the relationship between emotional labor and job stress. Conclusion : These findings suggest the need to enhance supervisor’s and coworker’s support through organizational-level leadership programs, improved work systems, and initiatives that strengthen cooperation among colleagues and foster a sense of community.

Research : This study aimed to examine the influence of top management's safety and health commitment on platform workers' safety and health behavior intention, and to verify the mediating roles of safety & health motivation and safety & health attitude. Methods : An online survey was conducted targeting 220 platform workers in South Korea (including food delivery, transportation, designated driving, and housekeeping services). The collected data were analyzed using regression analysis and mediation effect testing with SPSS 28.0 and SPSS Macro 3.4. Results : Top management's safety and health commitment had a significant positive (+) influence on safety and health motivation, safety & health attitude, and safety and health behavior intention. Both safety & health motivation and safety and health attitude also positively influenced safety and health behavior intention. Sequential multiple mediation was con-firmed, demonstrating that the leader's safety and health values are transferred to the employees' safety and health behavior through a psychological mechanism. Conclusion : For the purpose of improving the safety and health behavior level of platform workers, the sequential mediating path—through the cultivation of intrinsic motivation—was confirmed to be the most effective mechanism.

Purpose : This study aimed to analyze research trends on nurse burnout from 2015 to 2024 using text mining and topic modeling, focusing on the structural characteristics and temporal evolution of research themes. Methods : A total of 309 academic papers related to nurse burnout were collected from domestic databases (DBpia, RISS, and KCI). Text preprocessing and frequency analysis were conducted using NetMiner 4.5.1 and Latent Dirichlet Allocation (LDA) was applied to extract latent topics. The optimal number of topics was determined as six based on interpretability and topic coherence. Results : Six major topics were identified: (1) work demand and emotional exhaustion, (2) COVID-19 and occupational resilience, (3) work stress and job satisfaction, (4) clinical work experience, (5) psychological adaptation and mental health, and (6) emotional labor and organizational commitment. Emotional labor and job satisfaction remained central themes throughout the study period, while topics related to resilience and positive psychological capital expanded after the COVID-19 pandemic. The overall trend indicated a gradual shift in research focus from organizational factors to individual psychological resources. Conclusion : Nurse burnout research over the past decade has evolved from focusing on structural work stress to exploring adaptive and preventive factors such as resilience and psychological capital. These findings highlight the need for an integrated approach that combines organizational support and individual resource enhancement to effectively reduce nurse burnout and promote occupational well-being.

Purpose : This study aimed to examine the effect of occupational hazards exposure on self-rated health and to analyze the moderating effect of health and safety information provision among Korean wage workers. Methods : This secondary data analysis utilized the raw data from the 7th Korean Working Conditions Survey (2023), including 24,534 wage workers (weighted N=17,693,487). General characteristics, occupational hazards exposure (vibration, noise, high temperature, low temperature, smoke/fumes/dust, organic solvent vapors, chemicals, and infectious materials), self-rated health, and level of health and safety information provision were assessed. Hierarchical regression analysis was conducted to examine the effect of occupational hazards exposure on self-rated health and the moderating effect of information provision. Results : Higher levels of occupational hazards exposure were associated with poorer self-rated health (β=-.02, p<.001), and health and safety information provision had a positive effect on self-rated health (β=.13, p<.001). Information provision showed a significant moderating effect, buffering the negative relationship between occupational hazards exposure and self-rated health (β=.46, p<.01). Analysis by hazard type revealed significant moderating effects for all occupational hazards except vibration, with the strongest effects observed for low temperature exposure (β=.63), followed by infectious materials (β=.56), chemicals (β=.45), and high temperature (β=.43). Conclusion : Occupational hazards exposure negatively affects workers' self-rated health, while health and safety information provision serves as a protective factor that mitigates this negative effect. Systematic and sufficient health and safety information provision, particularly regarding temperature, chemical, and infectious material exposures, is recommended for workers’ health promotion in industrial settings.

Purpose : This study aimed to identify the factors influencing menopausal symptoms, work–family conflict, and e-health literacy on health-promoting behaviors among middle-aged female workers. A descriptive cross-sectional design was selected. Methods : The data were collected using a snowball sampling method by posting a recruitment notice and an online survey link on the nursing department’s online bulletin board. The data collection was conducted from September 1 to September 12, 2025, and a total of 173 responses were analyzed. The data were analyzed with descriptive statistics, t-tests, ANOVA, Pearson’s correlation analysis, and multiple regression analysis. Results : The mean score (out of 4) was 2.43±0.46 for health-promoting behaviors. Health-promoting behaviors showed a significant negative correlation with menopausal symptoms (r=–.35, p<.001), work interference with family (r=–.26, p=.001), and family interference with work (r=–.20, p=.010), whereas a significant positive correlation with e-health literacy (r=.43, p<.001). Multiple regression revealed that e-health literacy (β=.27, p<.001), coworker support (β=.26, p<.001), body-shape perception (β=–.22, p<.001), work interference with family (β=–.19, p=.040), menopausal symptoms (β=–.17, p=.011), and satisfaction with economic status (β=.15, p=.018) significantly influenced health-promoting behaviors (adjusted R²=.437, F=10.55, p<.001). Conclusion : The study’s results suggest that when developing health promotion programs for middle-aged female workers, it is essential to comprehensively consider factors such as e-health literacy, coworker support, work–family conflict, satisfaction with economic status, body-shape perception, and menopausal symptoms.

Purpose : This study was to examine the impact of climate change on the risk of occupational injuries and diseases in Korea and to provide evidence for developing effective prevention strategies. We described recent climate patterns, analyzed associations between climate factors and both heat-related illnesses and overall occupational injuries and diseases, and identified worker groups vulnerable to climate-related risks. Methods : This retrospective observational study used the data from the Korea’s Heat-Related Illness Surveillance System (HRISS), occupational injury statistics from the Korea Occupational Safety and Health Agency (KOSHA), and meteorological data from 67 nationwide measurement sites between 2022 and 2025. Analyses focused on May through September, when the heat exposure was the highest. Study subjects included cases of daily regional heat-related illness and worker-level injury records. Meteorological variables included temperature, humidity, and heat index. A total of 10,980 cases of heat-related illness and 142,022 cases of occupational injury and illness were analyzed using R 4.5.1. Results : From 2022 to 2025, the influence of humidity declined, whereas associations of temperature, heat index, daily temperature variability, and extreme heat days with heat-related illness soared. A continuous rise in mean heat index corresponded with increased incidence of daily heat-related illness. Logistic regression showed a marked rise in heat-related occupational injury risk, with a 2.41-fold higher likelihood of extreme heat–related incidence in 2024 compared with 2022. High-risk groups included small-scale workplaces (<300 employees), outdoor labor-intensive industries such as agriculture, forestry, and fisheries, construction, mining, and transportation, workers with less than one year term, and those in elementary occupations. Conclusion : Climate change has substantially intensified occupational heat-related hazards in Korea. Climatic indicators and workplace- and worker-level factors jointly increased injury and disease risks, underscoring the urgent need for targeted climate-adaptation strategies for vulnerable industries and worker populations.

Purpose : The purpose of this study was to explore nurse administrators’ experiences in personnel management in long-term care settings. Methods : The participants were 13 nurse administrators with experience in workforce management in long-term care. The data were collected from three focus group interviews conducted between July and August 2024 and analyzed using qualitative content analysis. Results : Four main themes and 14 subthemes were identified: ‘Burden of managing a heterogeneous workforce’, ‘Instability in securing personnel and lack of expertise’, ‘Organizational, strategic, and emotional efforts for workforce retention’, and ‘Workforce management strategies and practical competencies.’ Conclusion : Despite the challenges posed by managing a heterogeneous workforce and frequent staff turnover, nurse administrators guided their teams by demonstrating leadership through exemplary behavior, revealing patience and tolerance, and managing staff based on humanistic literacy. This study highlights the importance of an internal attitude grounded in humanistic literacy for workforce management in long-term care and suggests the development of effective personnel management programs based on the study’s results.

Purpose : This study aimed to explore hospital caregivers’ experiences of caring for patients with infections and their educational needs for infection control. Methods : This qualitative descriptive study utilized focus group interviews. Participants were 10 caregivers who had experience caring for patients with infections at a general hospital. The data were collected through four focus group interviews conducted from September 16 to 29, 2025, and analyzed using Elo and Kyngäs’s inductive content analysis method. Results : Seven categories and 30 subcategories emerged from the analysis: ‘diverse experiences of caring for patients with infections’, ‘psychological experiences related to caring for infected patients’, ‘patient characteristics and work environment causing caregiving difficult’, ‘absence of infection control support systems’, ‘educational content in need’, ‘preferred educational methods’, and ‘caregivers’ self-initiated coping and demands for improved working conditions’. Participants experienced fear and anxiety while caring for patients with tuberculosis, multidrug-resistant organisms, and scabies, yet they relied on verbal instructions from nurses or advice from fellow caregivers without systematic infection control education. Participants expressed needs for practice-oriented education including prior information on provision of infection, precautions by infection type, and donning/doffing of personal protective equipment. They preferred educational methods such as on-site information sheets, hands-on training, bedside small-group education, short modular videos, and repeated training. Conclusion : Despite performing tasks involving close contact with infected patients, caregivers were excluded from infection control education and support systems. Infection control education for caregivers should be designed considering learners’ characteristics, including age and educational background, as well as their 24-hour working environment, enabling immediate application in the field and behavioral internalization through repetition.

Purpose : This study aimed to identify the effects of ethical nursing competency and social intelligence on attitudes toward organ donation after brain death among intensive care unit (ICU) nurses working in university hospitals. Method : A survey was conducted with 168 nurses who had worked for over six months in the ICUs of university hospitals with 500+ beds in City D. The data were collected from July 5 to August 15, 2022, and analyzed using descriptive statistics, t-tests, ANOVA, Pearson’s correlation coefficients, multiple regression, and the PROCESS macro with SPSS/WIN 26.0. Result : Attitudes toward organ donation after brain death were significantly correlated with social intelligence (r=.160, 𝑝=.039). Factors influencing these attitudes included hope for organ donation (β=.511, 𝑝<.001), job position (β=.251, 𝑝<.001), and social intelligence (β=.143, 𝑝=.026). These variables explained 32.7% of the variance in attitudes toward organ donation after brain death. Conclusion : This study demonstrates that social intelligence is an important factor influencing ICU nurses’ attitudes toward organ donation after brain death. Based on these findings, developing and implementing educational programs designed to enhance social intelligence may positively affect nurses’ attitudes toward organ donation after brain death and ultimately help promote organ donation from brain-dead patients.

Purpose : The purpose of this study was to determine the relationship between work types (fixed night shift, rotating night shift, and fixed daytime work) and workers' health. Methods : The data were from the 7th Korean Working Conditions Survey (2023), focusing on questions related to night and shift work. The study analyzed 348 workers on fixed night shifts, 629 on rotating night shifts, and 44,907 on fixed day shifts. Results : The results showed that workers on rotating night shifts experienced higher levels of sleep-maintenance insomnia and non-restorative sleep compared to those on fixed night shifts and day shifts. Workers on rotating night shifts have also been shown to be most vulnerable to mental health problems. The risk of experiencing generalized fatigue was highest among fixed night shift workers. Conclusion : As the number of night shift workers steadily increases, ongoing efforts to improve their health are essential. Therefore, it is necessary to develop and reorganize various strategies and systems to effectively address these challenges.
