研究室紹介
Professor Ji-hyun Choi's research lab focuses on clinical and translational studies in neurology and nursing science, with a strong emphasis on neurological complications of toxic exposures—particularly methanol poisoning—and their management. The lab also investigates cognitive and psychological aspects in healthcare professionals and patients, including metacognition in nursing students, ethical decision-making in nursing, and mental health outcomes in infertility. Research spans from clinical neuroimaging (e.g., medial temporal lobe atrophy in Alzheimer’s disease) to hematological disorders with neurological manifestations, such as essential thrombocythemia presenting as large vessel stroke. The lab integrates clinical, psychological, and educational perspectives to improve patient outcomes and professional practice.

15Methanol poisoning results in neurological complications including visual disturbances, bilateral putaminal hemorrhagic necrosis, parkinsonism, cerebral edema, coma, or seizures. Almost all reported cases of methanol poisoning are caused by oral ingestion of methanol. However, recently there was an outbreak of methanol poisoning via non-oral exposure that resulted in severe neurological complications to a few workers at industrial sites in Korea. We present 3 patients who had severe neurological
Purpose: The purpose of this study was to understand the concept of metacognition and related attributes innursing students. Methods: This study used the concept analysis framework of Walker & Avant (2014). A literaturesearch was conducted using the PubMed, CINAHL, EBSCOhost, RISS, and DBpia databases with the keywords“nursing student” and “metacognition.” In total, 49 articles were selected for this study. Results: Metacognitionin nursing students is defined as understanding the acquired knowle
Background and Purpose Visual assessment of medial temporal-lobe atrophy (MTA) has been quick, reliable, and easy to apply in routine clinical practice. However, one of the limitations in visual assessments of MTA is the lack of widely accepted age-adjusted norms and cutoff scores for MTA for a diagnosis of Alzheimer’s disease (AD). This study aimed to determine the optimal cutoff score on a T1-weighted axial MTA Visual Rating Scale (VRS) for differentiating patients with AD from cognitively nor
In essential thrombocythemia (ET), cerebral infarction with large cerebral artery occlusion has rarely been reported. A 53-year-old male was admitted with left sided weakness. Brain magnetic resonance images revealed right internal carotid artery (ICA) territory infarction and proximal ICA occlusion. The blood laboratory examination demonstrated continuously increased platelet count (above 617,000/μL). Increased megakaroycytes and JAK2 V617F mutation were confirmed in the bone marrow biopsy. We
Purpose : The purpose of this study was conducted to grasp the trends of domestic research on infertile women and to suggest future research directions related to infertile women. Methods : This study utilized the methodological framework of Arskey and O'Malley as a literature review study on the subject scope. The research targeted studies published from 2003 to 2023 using electronic databases. Results : A total of 35 studies were included in the final analysis, and the analysis framework was s
연구목적: 본 연구는 간호사의 도덕적 고뇌와 윤리적 간호역량이 간호사의 재직의도에 미치는 영향을 파악하기 위해 수행되었다. 연구방법: 본 연구의 대상자는 종합병원급 이상의 의료기관에서 근무하는 간호사 191명이었다. 자료는 2023년 7월 11일부터 18일까지 수집하였으며, SPSS/WIN 23.0 프로그램을 사용하여 분석하였다. 연구결과: 간호사의 재직의도에 영향을 미치는 요인은 현재 부서의 재직기간(β=.22, t=3.20, p=.002), 이직 경험(β=.13, t=1.86, p=.064), 도덕적 고뇌(β=-.22, t=-3.15, p=.002), 윤리적 간호역량(β=.26, t=3.82, p<.001)이었다. 이들 네 변수는 간호사 재직의도를 19.7%를 설명할 수 있는 것으로 나타났다. 결론: 간호사의 재직의도를 높이기 위해서는 도덕적 고뇌를 완화시키기 위한 중재 방안을 모색하고, 윤리적 간호역량을 향상시키기 위한 체계적인 프로그램을 개발하고 적용해야 한다.
Background:Methyl salicylate overdose is usually caused by frequent topical applications or accidental ingestion, especially in children. Case Report:A 77yearold woman was admitted with an altered mental status, mild fever, and tachypnea. Initial laboratory analysis showed metabolic acidosis with respiratory compensation without significant abnormal signs. On admission, hyperthermia was aggravated by antipyretics. On the second day after admission, one of her family members found methyl salicyla

Methods : Conducted as a descriptive exploratory research, data were collected from 80 nurses in Seoul and Gyeonggi Province from August 1 to September 20, 2023. Results : Applying content analysis, the study identified four domains, twelve categories, and twenty-two meaningful statements, shedding light on nurses' perceptio
Purpose: The purpose of this study was to review the effect of foot care education in type 2 diabetes mellitus patients. Methods: A systematic literature search was conducted using Ovid-Medline, EMBASE, Cochrane library, CINAHL, PsycINFO, RISS, NDSL, and KISS to identify studies reported in English or Korean from 2000 to 2022. Results: From the 3,070 studies extracted, 13 were selected for review. The studies were classified as information study, design study, subject study, intervention analysi
목적 본 연구의 목적은 빅데이터를 활용하여 청소년의 에너지 드링크에 대한 인식을 탐색하는 것이다. 방법 빅데이터 분석을 위해 주요 포털사이트(“네이버”, “다음”, “구글”)에서 2023년 3월 31일부터 2024년 3월 30일까지 생성된‘청소년’, ‘에너지 드링크’ 관련 문서를 텍스톰을 이용하여 수집하였으며, 총 15,959건의 문서를 수집하였다. 텍스트 마이닝을 위해관련성이 없거나 부정확한 단어를 제거하였으며, 출현 빈도가 높은 단어 50개를 추출하고 정제를 통해 의미가 높은 단어를 중심으로50개의 키워드를 도출하였다. 결과 NetDraw와 UCINET 프로그램을 이용하여 빈도분석, TF-IDF(Term Frequency - Inverse Document Frequency)분석, 중심성분석, CONCOR(Convergence of iteration Correlation)분석을 실시하여, 주요 키워드 간 군집화 결과를 조사하였다. 그 결과, 그룹 1은 카페인 섭취의 일상화, 그룹
Purpose: To comprehensively review nurses’ experience of caring for COVID-19 inpatients in Korean hospitals. Methods: A qualitative meta-synthesis suggested by Thomas and Harden was conducted in this study. Seven qualitative studies were selected and synthesized to describe experiences of ward nurses caring for COVID-19 inpatients in Korean hospitals. Results: The following four themes with 13 sub-themes were synthesized from qualitative studies: Unstable emotions experienced in the care of COVI
Adrenoleukodystrophy (ALD), caused by the alteration in ABCD1 gene, is an X-linked progressive neurodegenerativedisease characterized by the accumulation of very long chain fatty acids (VLCFA). ALDshows highly variable clinical presentations. The proband, a 53-year-old man, presented with a six-yearhistory of progressive spastic paraparesis and voiding difficulty. The plasma VLCFA level was elevated. Because c.1394-2A>G ABCD1 mutation was identified through genetic test, the patient was diagnose
터키는 이스탄불 협약(Istanbul Convention)에 최초로 가입(2011)하고 최초로 탈퇴(2021)한 국가이다. 이스탄불 협약은 여성 폭력을 여성 차별과 여성 인권 침해의 한 형태로 명시한 최초의 국제 협약이다. 터키가 탈퇴하면서 이스탄불 협약은 ‘이스탄불’ 없는 협약이 되었다. 터키의 집권 여당인 AKP(Adalet ve Kalkınma Partisi)는 세속주의 국가에서 민주적 선거를 통해 20년간 장기집권을 이어가고 있는 이슬람 정당이다. 이러한 AKP 정권은 어떠한 배경과 동기에서 이스탄불 협약에 가입하고 탈퇴하기로 하였을까? 본 연구는 AKP가 정권을 확장하고 유지 및 안정화하는 과정의 경과에 따라 이스탄불 협약 가입과 탈퇴를 정치화하였다는 점에 주목하여 그 과정을 설명하고자 하였다. 집권 초기 AKP는 세속주의 기득권층을 견제하고, 정권 정당성을 확보하는 한편 유럽화라는 국가적 숙원을 성취하기 위해 민주주의, 인권 등의 보편적 가치를 실용적으로 추구했다. AKP
본 연구는 고맥락 언어 환경인 한국어 대화에서 발화자와 수신자 간의 침묵 시간(600 ms, 1,200 ms, 1,800 ms)과 화행 유형(요청, 평가)이 한국 청년 청자의 긍정-부정 판단에 미치는 영향에 대해 살펴보고자 하였다. 20–30대 한국 청년층 101명이 가상의 전화 통화 과제에 청자로 참여하였으며, 청년층이 익숙하게 접할 수 있는 요청과 평가 상황을 듣고 수신자의 동의 정도를 평가하도록 하였다. 그 결과, 발화자와 수신자 간의 침묵 시간이 길어질수록 청자의 긍정적인 평가는 전반적으로 감소하는 경향을 보였다. 요청 상황에서는 짧은 침묵이 긍정적으로 해석되어 협력할 의지가 있는 것으로 간주된 반면, 긴 침묵은 의심과 불편함을 유발하였다. 마찬가지로 평가 상황에서는 짧은 침묵이 긍정적인 판단을 증가시켰고, 긴 침묵은 발화자와 전달된 정보의 신뢰성을 저하시켰다. 본 연구 결과는 침묵이 단순히 대화의 공백이 아니라 의사소통 과정에서 중요한 비언어적 단서로 기능하며, 침묵의 적절
