Abstract
Background and purpose: The emergency department of a hospital is akin to its heart, where smooth operations can save many lives. This research aims to reduce patient waiting time in the emergency department using simulation techniques.
Methods: This descriptive-analytical study was conducted cross-sectionally in 2019 at the Qaim Hospital in Mashhad. The study focused on accurately modeling the patient flow process in the emergency department using simulation techniques and Arena software. Key performance indicators such as patient waiting time, number of discharged patients (system output), length of stay, resource efficiency, and improvements in the emergency department were evaluated.
Results: The simulation model's results indicated that the laboratory, specialist doctor examination, and pharmacy departments had the longest waiting times in this department, respectively.
Conclusion: To reduce patient waiting times and improve conditions, the most effective and cost-efficient solution is to add a laboratory technician to the laboratory department during the [15-23] shift at Qaim Hospital in Mashhad, which is projected to decrease patient waiting times by 66 minutes.

Abstract
Background and purpose: Nurse's thermal comfort in a clinical setting directly impacts their performance and the quality of patient care. This study investigates how two key environmental factors—ambient light intensity and Correlated Color Temperature (CCT)—influence this perception of thermal comfort.
Methods: This experimental study was conducted in a controlled laboratory setting with 60 healthy female nurses over four months (December 2024–March 2025). We assessed the effects of light intensity (at two levels: 300 and 750 lux) and CCT (at three levels: 2700 K, 4000 K, and 7800 K) on perceived thermal comfort. Data were analyzed using a two-way Analysis of Variance (ANOVA).
Results: Light intensity, CCT, and their interaction all had a statistically significant effect on nurses' perceived thermal comfort (p < .05). Optimal thermal comfort was reported at a CCT of 4000 K under both 300 and 750 lux intensities. At a warm CCT (2700 K), comfort was maintained at 300 lux but not at 750 lux. Conversely, at a cool CCT (7800 K), the 300 lux condition was perceived as uncomfortable, while the 750 lux condition was reported as comfortable.
Conclusion: This study demonstrates a significant interaction between light intensity and CCT in shaping thermal perception in a clinical context. The findings suggest that lighting design in healthcare facilities must consider both metrics simultaneously to optimize the work environment. A neutral CCT of 4000 K appears to be the most robust for maintaining thermal comfort across different light levels, highlighting its potential as a design standard for healthcare settings.
