Purpose: The main purpose of this article is to explore the plan to foster the experts in reserve forces of the Korean armed forces based on a review of the operation of reserve forces in foreign countries, such as the United States and Germany, in consideration of the rapidly changing international situation and security changes on the Korean Peninsula following the Russian invasion of Ukraine. It is intended to examine the relevant development, and at the same time, while there are differences in terms of policy and implementation aspects, it is intended to make suggestions regarding policy development by deriving implications through the comparative analysis of the reserve forces system of Korea and the United States. Method: Considering the characteristics of this study, it was primarily composed of literature studies such as official documents, research papers, and related degree dissertations of the Korean and U.S. governments, Inter-net materials. As examples of the development of reserve forces in foreign countries, including the United States, case analysis of the reserve forces service system and organization method, reserve forces training, etc., were used. Based on which, various implications were drawn for fostering the reserve forces experts for Korea's elite reserve force. Result: For emphasis purposes, the U.S. and Germany legally maintain the same status as active duty and reserve forces. This is because budgeting and policy establishment for reserve forces are applied in the same manner as in active duty. In particular, the U.S. develops and applies the AGR and ADOS systems based on the legal basis and budget, and operates the reserve force as a unit from the peacetime. However, Korea is currently conducting a short mobilization call training for three days and two nights. In case of emergency, after the gen-eral mobilization order is issued, the unit enters into the relevant unit to increase the mobilization and establish the unit. Moving forward, it is necessary to train the reserve forces experts who can contribute to shortening the gap between peacetime and when the general mobilization order is issued. Conclusion: The lessons learned from the Russo-Ukraine war are the spirit of armed struggle from the leader to the people, the strategy and tactics to operate the weapon system, and above all, the very importance of mobilizing the reserve force that can demonstrate practical combat power in the battlefield in case of emergency. As such, it is very important to prepare a plan for fostering the reserve forces experts in consideration of changes in the international order in the 21st century, declining population, changes in war patterns such as hybrid war-fare shown in the Russo-Ukraine war, and Korea's future defense environment, among the key tasks of the De-fense Reform 4.0.
Longitudinal Stress Fracture of the Ulna: Forearm Splint in a Military Cook With Wok Pot Use

Stress fractures of the upper extremities are rare. Here we report the case of a 20-year old man who presented with left forearm pain for 6 weeks. He worked as a military cook and used a wok pot. Plain radiography showed periosteal reaction with cortical thickening at the midportion of the ulnar shaft without a transverse fracture line. Magnetic resonance imaging showed diffuse bone marrow edema along the ulnar shaft. Segmental cortical thickening with periosteal edema was observed on the volar side of the midshaft of the ulna. Although a typical transverse fracture line was not clearly visible, T2-hyperintense curvilinear foci were observed within the cortical thickening. Coronal T1-weighted enhanced imaging demonstrated an obliquely elongated abnormality within the cortical thickening. A longitudinal stress fracture of the ulna, of the intracortical subtype, was diagnosed. Follow-up plain radiography and computed tomography confirmed an ongoing solid union after plaster cast application. The non-neutral posture while using a straighthandled wok for flipping and repeated action likely caused cumulative trauma to the patient’s upper extremity. Clinical history taking and imaging studies using cross-sectional images may facilitate the early and accurate diagnosis of an unusual pattern of ulnar stress fracture.

Background: Coronavirus disease 2019 (COVID-19) outbreaks occur in hospitals in many parts of the world. In hospital settings, the possibility of airborne transmission needs to be investigated thoroughly. Materials and Methods: There was a nosocomial outbreak of COVID-19 in a hematologic ward in a tertiary hospital, Seoul, Korea. We found 11 patients and guardians with COVID-19 through vigorous contact tracing and closed-circuit television monitoring. We found one patient who probably had acquired COVID-19 through airborne-transmission. We performed airflow investigation with simulation software, whole-genome sequencing of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Results: Of the nine individuals with COVID-19 who had been in the hematologic ward, six stayed in one multi-patient room (Room 36), and other three stayed in different rooms (Room 1, 34, 35). Guardian in room 35 was close contact to cases in room 36, and patient in room 34 used the shared bathroom for teeth brushing 40 minutes after index used. Airflow simulation revealed that air was spread from the bathroom to the adjacent room 1 while patient in room 1 did not used the shared bathroom. Airflow was associated with poor ventilation in shared bathroom due to dysfunctioning air-exhaust, grill on the door of shared bathroom and the unintended negative pressure of adjacent room. Conclusion: Transmission of SARS-CoV-2 in the hematologic ward occurred rapidly in the multi-patient room and shared bathroom settings. In addition, there was a case of possible airborne transmission due to unexpected airflow.
