Purpose
This study aimed to examine the influence of health literacy and autonomy support on health behavior adherence among patients with premature coronary artery disease (PCAD), defined as onset before age 55 years in males and 65 years in females. Methods: A descriptive, cross-sectional design was employed. Data from 153 patients were collected at a hospital in Seoul, South Korea, between January and March 2023. Statistical analyses included the independent t-test, one-way analysis of variance, Pearson correlation coefficients, and hierarchical multiple regression, conducted using IBM SPSS WIN ver. 27.0. Results: Health literacy (β=.36, p<.001) was the strongest determinant of health behavior adherence. A disease duration of more than one year (β=.17, p=.016) was positively associated with adherence, while male sex (β=–.16, p=.039) and the absence of comorbidities (β=–.17, p=.011) showed significant negative associations. Autonomy support from healthcare providers was not significantly associated with health behavior adherence. Conclusion: Healthcare professionals should prioritize improving patient health literacy through tailored communication and educational strategies. Male patients and those newly diagnosed should be recognized as vulnerable groups for low adherence. Targeted interventions should be designed to meet their specific needs. Furthermore, patients with PCAD should be guided to increase their awareness and understanding of their condition.

Purpose
This study aimed to comprehensively understand the experiences of emergency nurses performing triage during the peak and plateau periods of the Coronavirus Disease 2019 (COVID-19) pandemic over the past two years. Methods: Twenty triage nurses from three emergency medical centers were recruited through purposive and snowball sampling. Data collection occurred from February to May 2022 via focus group interviews and was analyzed using qualitative content analysis. Results: The experiences of emergency nurses in triage revealed four themes: "changes in priorities due to infectious diseases", "barriers to tirage", "the emotional burden experienced by triage nurses", and "the journey toward growth". The pandemic heightened the focus on infection screening in triage. Triage nurses faced numerous challenges concerning their own safety and that of their patients and encountered difficulties in performing triage. Nonetheless, these experiences provided them with opportunities for professional growth. Conclusion: The experiences of nurses performing triage during the peak and plateau periods of the COVID-19 pandemic provide valuable insights for future preparedness and coping strategies in the face of similar infectious disease outbreaks. It is necessary to establish integrated triage guidelines for patient safety, develop operations manuals for triage, implement policies on staffing standards, and provide mental health support for triage nurses during pandemics.
