Purpose: In this qualitative descriptive study, we aimed to explore the experiences of nurses providing end-of-life (EOL) care in an emergency department (ED) setting and identify the associated challenges and implications for clinical practice. Methods: Twelve nurses with over 1 year of EOL care experience in the ED were interviewed. The collected data were analyzed using thematic analysis, as outlined by Braun and Clarke. Results: Five main themes with corresponding subthemes were identified: (1) Inadequate Environment for EOL Care, including physical environment barriers for a dignified death and emotional restraint in a chaotic setting; (2) Impact of Life-Sustaining Treatment Decision Complexity, encompassing complicated dynamics of family decision-making and compromised care quality in the decision-making process; (3) Managing Care Relationships in Physician-Limited Settings, manifested as navigating limited physician communication and bearing the emotional weight of EOL care; (4) Challenges in Protecting Patients’ Rights, characterized by powerlessness in the face of silent patients and confusion from reversed decisions by families; and (5) Actualizing Compassionate EOL Care, ensuring dignity through purposeful actions and navigating environmental barriers to dignified care. Conclusion: We highlight the need for systematic changes in the ED to better support EOL care, including the development of culturally sensitive communication protocols, shared guidelines for decision-making, and improved collaboration between healthcare professionals. These findings provide valuable insights into enhancing EOL care in EDs. Future efforts should focus on policy changes, tailored education programs, and support systems that address the multifaceted needs of patients, families, and healthcare providers.

Buckwheat (Fagopyrum esculentum), which is a traditional Korean crop, has been known as a health food due to its rich nutrition. This study was conducted to evaluate the change in flavonoid content of flowers and seeds during post-flowering growth of Korean tartary buckwheat variety ‘Hwanggeummiso’, with the aim of providing basic data for the development of functional food and feed additive. Tartary buckwheat took 69 and 99 days from the sowing date to reach the flowering and maturity stages, respectively. As a result of examining the flavonoid components of each part of tartary buckwheat, chlorogenic acid, rutin, and isoquercitrin of flowers increased from the flowering period on 22 May (0 days after flowering) to 42 days after flowering, while quercetin increased until 21 days after flowering and then decreased thereafter. In seeds, chlorogenic acid, rutin, and isoquercitrin were most abundant at the time of seed-bearing on 14 days after flowering, and showed a decreasing tendency thereafter. On the other hand, quercetin showed a tendency to increase until 21 days after flowering and then decrease. Overall, the flavonoid content was higher in flowers than in seeds, with rutin being particularly prominent. Based on this, the possibility as food materials and feed additives was confirmed using buckwheat produced in Korea.
