Purpose: A nationwide study (2012-2017) of preventable trauma death rates (PTDR) showed a 15.3% decrease after Regional Trauma centers were initiated. However, in non-trauma centers with an Emergency Department there is limited data of preventable mortality in trauma patients. Therefore, the purpose of this retrospective study was to investigate preventable mortality in trauma patients in a nonregional trauma center and determine the effect of initiating a Trauma Team. Methods: There were 46 deaths of trauma patients recorded in the National Health Insurance service Ilsan Hospital (NHISIH) in South Korea from January 2019 to December 2021. These patients’ preventable deaths were analyzed by an expert panel review considering the implementation of the Trauma Team in April 2020. Results: All deaths were attributable to blunt trauma with an average Injury Severity Score of 26.0 ± 19.2, Revised Trauma Score of 5.05 ± 3.20 and Trauma and Injury Score of 56.6 ± 41.3. The most frequent cause of death was traumatic brain injury followed by respiratory arrest. The most frequent error was delayed transfusion followed by delayed treatment of bleeding. Treatment errors occurred the most in the Emergency Room followed by the Intensive Care Unit. The PTDR of patients before the involvement of a Trauma Team (January 2019 to March 2020) and after the Trauma Team was initiated in April 2020 decreased from 27.27% to 4.27%, respectively (p = 0.021). Conclusion: The introduction of a dedicated Trauma Team in a non-regional trauma center significantly reduced the overall PTDR in trauma patients.

본 논문에서는 전동 킥보드 주행 중 배터리 폭발 방지를 위한 케이스 제작을 위해 리튬 폴리머 배터리에 물리적인 충격 및 고온에서의 열 충격을 가하는 실험을 통해 제작 조건을 찾고자 하였으며 리튬 폴리머 배터리 팩 케이스의 구성별 냉각 효과를 실험을 통해 비교 분석하였다. In this paper, for the manufacture of a case to prevent battery explosion while driving an electric scooter, physical shock and thermal shock at high temperature were applied to the lithium polymer battery to find the manufacturing conditions, and the cooling effect of the lithium polymer battery pack case was investigated. Comparison and analysis were conducted through experiments.

Purpose: Despite guidelines on the prevention of central venous line-associated bloodstream infection, itis left to the clinical judgment of the attending physician to determine the risk of infection and how longa central line should remain in place. This study aimed to identify risk factors for peripherally insertedcentral venous catheter (PICC)-associated infection. Methods: This retrospective study included 1,136 patients with a PICC who were hospitalized at theNational Health Insurance Service Ilsan Hospital (January 2015 to January 2022). Electronic medicalrecords were reviewed for patients with positive blood cultures. Patients with suspicion of infection atthe PICC insertion site or with unclear infection at other sites were defined as having a PICC-associatedinfection. Results: Thirty-five patients (3.08%) had a PICC-associated infection. There were significant differencesin hypertension (p = 0.026), lung disease (p = 0.001), PICC duration > 14 days, and antibiotic use beforePICC insertion (p = 0.016) between no PICC-associated infection, and infection in the bloodstream. Total parenteral nutrition with PICC was not significantly different between groups. Logistic regressionanalysis identified hypertension, lung disease, PICC duration > 14 days (OR 2.088, 95% CI 1.032-4.224, p = 0.041), and antibiotic use before PICC insertion (OR 0.159, 95% CI 0.049-0.515, p = 0.002) asindependent risk factors for PICC-associated infection. Conclusion: The study suggested that PICCs maintained longer than 14 days is a risk factor for PICC-associated infection. Antibiotic use prior to PICC insertion was observed as a negative factor for PICC-associated infection.
