Aims and Objectives:The purpose of this study was to examine work-related stress, nurse-physician collaboration and clinical reasoning competence to identify the factors that affected the triage competence of emergency room nurses.Background: A quick and accurate treatment plan for patients is first determined by a triage nurse. Triage competence is an indispensable requirement for emergency room nurses.Design: A cross-sectional design was adopted. Methods:The participants comprised 156 emergency room nurses in South Korea who had more than 1 year of experience working in an emergency room. The collected data were analysed using SPSS 28.0. Self-reported data were collected via the Korean Nursing Stress, Nurse-Physician Collaboration, Nurse Clinical Reasoning, Emergency Room Nurse Triage Competence assessing work-related stress, nursephysician collaboration, clinical reasoning competence and triage competence. In the analyses, multiple regression analysis using the enter method was conducted. We have followed through the STROBE checklist for the preparation of this manuscript.Results: Triage competence significantly differed according to the age (F = 9.93, p < .001), clinical experience (F = 18.82, p < .001), emergency department experience (F = 12.07, p < .001), triage experience (t = 4.40, p < .001) and if nurses had a triage certificate (t = 4.85, p < .001). The factors that influenced triage competence included clinical reasoning competence (β = .36, p < .001), emergency department experience (β = .21, p = .006), work-related stress (β = .18, p = .007) and nurse-physician collaboration (β = −.17, p = .009); these factors accounted for 38.1% of the variance in triage competence. Conclusion:The results of this study show that efforts to improve triage competence should be based on clinical reasoning. In addition, an effective plan should be devised to improve nurse-physician collaboration and work-related stress.

The borehole thermal energy system, KINTEX, located in Ilsan, South Korea was simulated using TRNSYS. The effect of the depth and spacing of the boreholes in this Borehole Thermal Energy Storage (BTES) system on the average stored energy and ground temperature were investigated over three years of its operation. Borehole thermal energy storage was simulated using the Duct Ground Heat Storage Model built in TRNSYS. The BTES system is composed of solar collectors, a heat exchanger, borehole thermal energy storage, and a thermal storage tank. The effects on the internal energy of the system were investigated by varying borehole depth and spacing while the volume and number of boreholes were kept constant. The total number of boreholes is 90 and all boreholes are connected in series. The borehole depths varied from 40 to 47.5[Formula: see text]m with steps of 2.5[Formula: see text]m, and the borehole spacing varied from 2.5 to 4.0[Formula: see text]m while the total volume of the BTES was maintained at 21,[Formula: see text]236 [Formula: see text]m3. The internal energy stored ranged from 1528.91 GJ to 1618.69 GJ over three years of calculations. With an increase of borehole depth and associated decrease of borehole spacing, the internal energy increased and ground temperatures approached 35∘C over a simulation period of three years.
