Pilot Fatigue and Required Rest period for Korean Air Force pilots flying High-performance Aircraft
No full textOver the years, significant advancements have been made in aircraft technology and in understanding the detrimental effects of fatigue on flight performance. However, integrating these advancements into crew rest regulations, particularly for the Republic of Korea Air Force (ROKAF) operating high-performance jets, requires further review. This study employs a systematic review with thematic analysis to assess whether ROKAF’s current rest regulations are sufficient. Relevant studies were identified from English-language databases (e.g., FAA, ICAO, Google Scholar) and Korean-language databases (e.g., RISS, KCI). Titles and abstracts were initially reviewed, followed by full-text assessments based on inclusion and exclusion criteria focusing on military and civil aviation regulations, fatigue management, and the physical and psychological demands of high-performance jet pilots. Data from 46 selected studies were categorized into three themes: (1) required capabilities in military aviation, (2) the influence of fatigue on pilot safety and performance, and (3) a comparative examination of rest period regulations across ROKAF, U.S. military, FAA, EASA, and Korean civil aviation. Findings highlight the significant impact of fatigue on cognitive functions, including decision-making, situational awareness, multitasking ability, and the capacity to process complex information. Additionally, compared to standards used in the U.S. military and international civil aviation, ROKAF’s current crew rest regulations appear less aligned with current fatigue research and best practices, particularly regarding circadian rhythms and ensuring eight hours of uninterrupted sleep. Based on these findings, the study recommends revising ROKAF’s rest period regulations to incorporate circadian rhythm research, developing compensatory standards for various operational environments, and adopting Fatigue Risk Management Systems (FRMS) iv as seen in civil aviation. It also suggests considering the unique physiological and operational fatigue in high-performance jet operations and further informing fatigue management strategies
Machine Learning-Enhanced Optimization for the Real-Time, Secure, and Efficient Operation of the Energy-Water-Hydrogen Nexus
No full textGiven the escalating urgency of climate change, our research addresses the imperative need to curb carbon emissions, particularly from the electricity sector, which accounts for a quarter of total emissions in the U.S. We propose integrated systems, such as the energy-water nexus (EWN) and an innovative concept known as the energy-water-hydrogen (EWH) nexus, which integrates renewable energy sources (RESs) with green hydrogen production through water electrolysis. These concepts align seamlessly with the nation’s commitment to global climate agreements, including the Paris Agreement. Furthermore, green hydrogen—a clean and efficient energy source produced via water electrolysis powered by renewable energy—emerges as a pivotal solution to addressing climate change challenges. These innovative engineering concepts show promise in bolstering greater renewable energy integration, ensuring the secure operation of water and power systems, and managing energy while reducing operational costs. However, the complexity of power, water, and hydrogen systems intensifies when collaborating, particularly with the high penetration of intermittent RESs. Advanced AI-based optimization methods are crucial to addressing these intricacies and uncertainties. Our research focuses on applying advanced optimization techniques, such as convexification and machine learning, to efficiently solve these complex problems across various concepts, from virtual energy storage and virtual power plant applications to secure operations and real-time optimal operations of the EWH nexus

Disaster Exercise: Evaluating MCI Triage Training
No full textAbstract
Study Objectives
The primary objective of this study was to evaluate the effectiveness of a didactic lecture-based training on mass casualty incident (MCI) triage performance among first- and second-year medical students. Specifically, the study aimed to measure improvements in overall triage accuracy, as well as reductions in over-triage and under-triage rates for both adult and pediatric patients.
Methods
This study employed a pre-test/post-test design involving 31 participants. Participants completed an electronic pre-test consisting of 30 patient scenarios (20 adult and 10 pediatric) before attending a 40-minute didactic lecture on MCI triage principles. The lecture covered the identification of MCI scenarios, the roles of first responders and physicians, and the application of the START (adult) and JumpSTART (pediatric) triage algorithms. Following the lecture, participants completed the same assessment as a post-test. Statistical analysis was performed using paired-samples t-tests to evaluate changes in triage performance metrics.
Results
The analysis revealed significant improvements in several key areas. Overall Correct Triage Decisions increased from pre- (M = 17.71, SD = 3.07) to post-intervention (M = 20.52, SD = 3.99), t(30) = -4.37, p \u3c .001, with a large effect size (Cohen’s d = -0.79). Overall Accuracy Percentage also improved significantly, t(30) = -4.37, p \u3c .001, d = -0.77. Adult Correct Triage and Adult Accuracy Percentage showed significant gains, t(30) = -4.68 and -4.67 respectively, both p \u3c .001, with large effect sizes (d ≈ -0.84). Pediatric Correct Triage and Pediatric Accuracy Percentage improved significantly, t(30) = -3.66, p \u3c .001, d ≈ -0.66.
Conclusions
The findings of this study indicate that didactic lecture-based training significantly enhances MCI triage accuracy and reduces under-triage rates among first- and second-year medical students. These results support the integration of MCI triage training into early medical education curricula to improve preparedness for real-world disaster scenarios. Future training programs should consider incorporating high-fidelity simulations, longitudinal curriculum integration, and interprofessional training modules to further enhance the effectiveness of MCI triage education
Distinguishing Acute Cardiac Events from Chronic Troponin Elevation: Integrating High-Sensitivity Troponin Trends with Objective Ischemic Evidence Under the 4th UDMI Across Diverse Renal Function Profiles
No full textThe Fourth (4th) Universal Definition of Myocardial Infarction (UDMI) provides a standardized framework to enhance diagnostic accuracy and clinical decision-making. However, challenges can arise due to the use of subjective clinical assessment in diagnostic criteria or in the presence of impaired renal clearance. This study modifies the 4th UDMI by requiring objective ischemic evidence to improve consistency in myocardial infarction (MI) classification and applies it across diverse patient populations.
In this retrospective study, patients who presented to the emergency department (ED) with 99th percentile high sensitivity cardiac troponin (hs-cTn) values were classified using the modified 4th UDMI into the categories of Type 1 MI (T1MI), Type 2 MI (T2MI), acute non-ischemic myocardial injury (NIMI), or chronic NIMI. Patients were also stratified based on estimated glomerular filtration rate (eGFR)
Of the 1,755 qualifying, patients 0.3% (n = 5) were classified as T1MI, 8.2% (n = 145) as T2MI, 22.7% (n = 399) as acute NIMI, and 68.7% (n = 1206) as chronic NIMI. Patients with infarction had a 19.33% mortality rate (29/150), significantly higher than the 7.41% mortality rate (119/1,605) in myocardial injury (p \u3c 0.0001). When stratifying by eGFR, median two-hour troponin levels did not differ significantly. Among the patients with eGFR data, acute NIMI accounted for 378 cases (22.3%), with 82 (21.7%) occurring in the GFR
The consistency of MI and injury classifications across renal function groups supports the validity of the modified 4th UDMI, even in the presence of renal impairment that influences troponin dynamics and patient outcomes
