研究室紹介
Professor Yun-Hee Choi's research lab specializes in clinical and translational research with a focus on emergency medicine, hepatoprotection, and critical care biomarkers. The lab investigates diagnostic imaging performance in pediatric head trauma, evaluates natural compounds for hepatoprotective effects against drug-induced liver injury, and explores predictive biomarkers such as NGAL in post-cardiac arrest acute kidney injury. Additionally, the lab contributes to understanding health-related behaviors, including body image and leisure satisfaction among young adults, and manages cases of severe toxic exposures, such as glyphosate-surfactant poisoning.

15OBJECTIVES: Facial bone fractures secondary to head trauma are more common in children than in adults. Recently, multidetector row computed tomography (CT) has been considered superior to conventional radiography. Some studies have reported that facial soft tissue injuries require both facial and brain CT and that brain CT is helpful in screening facial bone fractures. However, these studies included only adult patients. The aim of this study was to evaluate the diagnostic performance of brain C
BACKGROUND/OBJECTIVE: (AK) has widely been utilized for the purpose of general health improvement among Asian, its functionality and mechanism of action. The aim of this study was to determine the protective effect of ethanol extract of AK (AK-Ex) on acute hepatotoxicity induced by acetaminophen (AAP) in HepG2 human hepatocellular liver carcinoma cells and HepaRG human hepatic progenitor cells. MATERIALS/METHODS: AK-Ex was prepared HepG2 and HepaRG cells were cultured with various concentrations
BACKGROUND: Serum neutrophil gelatinase-associated lipocalin (NGAL) could be used as a predictive marker of acute kidney injury (AKI) in patients with return of spontaneous circulation (ROSC) after out-of-hospital cardiac arrest (OHCA) who are managed with targeted temperature management (TTM). However, the NGAL measurement timepoints vary from immediately after ROSC to several days later. The primary objective of this study was to determine an association between AKI and NGAL, both immediately
BACKGROUND: To compare the 1997 American Diabetes Association (ADA) criteria with the 1985 World Health Organization (WHO) criteria in categorization of the diabetes diagnostic status of Koreans and to define clinical characteristics of subjects diagnosed differently by the two criteria. METHODS: In 810 Korean subjects, we analyzed blood glucose and insulin response during 75 g oral glucose tolerance test (OGTT). According to current WHO criteria, the cutoff values of FPG which distinguish norma
본 연구의 목적은 여대생들의 신체이미지(body image)에 대한 차이지각을 파악하고 이에 따른 여가활동유형이 여가만족(leisure satisfaction)에 어떠한 영향을 미치는지 규명하는 것이다. 본 연구에서는 측정도구로 설문지를 사용하였고, 자기평가기입법(self-administrated method)을 통해 응답하게 하였다. 본 연구의 대상은 서울에 소재하고 있는 4년제 대학교의 여대생들을 모집단으로 설정하고, 577부의 자료를 실제분석에 사용하였다. 본 연구의 자료처리는 windows용 SPSS 13.0 version을 이용하였다. 신체이미지 차이지각에 따른 여가활동유형이 여가만족에 미치는 영향에 있어서 작은 차이지각 집단은 모든 변수에서 사교오락 활동이 인과관계가 있는 것으로 나타났고, 휴식적 만족을 제외한 모든 변수는 관람감상활동에 인과관계가 있는 것으로 나타났으며, 스포츠 활동은 신체적 만족과 환경적 만족에 인과관계를 나타냈다. 신체이미지 차이지각이 큰 집단은 모든
Glyphosate-surfactant is one of the most commonly used herbicides in the world. Its key component, glyphosate, is a competitive inhibitor of the shikimate pathway, a metabolic pathway found only in plants. However, severe intoxication, including lethal cases by ingestion of, glyphosate-surfactant has been reported. We describe the full recovery of two patients from glyphosate-polyoxyethyleneamine surfactant intoxication and multi-organ system failure following continuous renal replacement therap
This study tests the effect of corporate bond rating changes on common stock prices in order to compare the difference between pre-Financial Crisis(2008) period and post-Financial Crisis(2008) period in Korea. Sample consists of 146 events coming from rating change event from 2007 to 2009. The rating change data are obtained from credit rating agencies. Samples are subdivided into several subgroups. First, pre-Financial Crisis period and post-Financial Crisis period. Second, within-classes, acro
본 연구는 월세에 거주하는 1인 가구의 주거비 부담 실태를 연령대별로 파악하고 성별 간 차이를 확인하는 데 목적이 있다. 이를 위해 한국복지패널 18차(2023년) 데이터를 활용하였다. 분석 대상은 월세에 거주하는 청년층(20~39세), 중장년층(40~64세), 노년층(65세 이상)이다. 주거비 부담은 RIR(Rent to Income Ratio) 지수를 사용하여 측정하였으며, 모형 검증에는 분위수 회귀분석을 적용하 였다. 주요 분석 결과는 다음과 같다. 첫째, 월세 거주 1인 가구 여부는 중장년층과 노년층의 주거비 부담에 유의미한 영향을 미쳤으며, 특히 여성 1인 가구일수록 주거비 부담이 남성보다 높게 나타났다. 둘째, 청년층에서는 1인 가구 여부보다 가처분 소득과 공공임대주택 이용 경험 여부가 주거비 부담에 주요 영향을 미치는 요인으로 확인되었다. 셋째, 공공임대주택 이용 경험은 전 연령대에서 주거비 부담 을 유의미하게 완화하는 요인으로 작용하였다. 넷째, 지역적 요인은 중장년층
