研究室紹介
Professor Kyung Hee Jo's research lab specializes in biomedical engineering and clinical neuroscience, focusing on the development of advanced diagnostic tools for cerebrovascular diseases and infectious liver conditions. The lab investigates the pathophysiology of cardioembolic stroke using neuroimaging techniques such as susceptibility vessel sign (SVS) on T2*-weighted GRE MRI, while also pioneering nanosensor technologies for early detection of hepatitis B surface antigen (HBsAg). Research spans from clinical stroke mechanisms to innovative field-effect transistor (FET)-based aptasensors using conductive nanofilms.

15BACKGROUND AND PURPOSE: In contrast to platelet-rich white thrombi, red thrombi in the heart are rich in fibrin and trapped erythrocytes. The magnetic susceptibility effect of deoxygenated hemoglobin in red thrombi may result in hypointense signals on T2*-weighted gradient echo imaging (GRE). We tested the hypothesis that a GRE susceptibility vessel sign (SVS) is specific for cardioembolic stroke. METHODS: This retrospective study examined data from acute ischemic stroke patients who underwent d
Hepatitis B virus (HBV) infection is a major worldwide health issue causing serious liver diseases, including liver cirrhosis and hepatocellular carcinoma. Monitoring the serum hepatitis B surface antigen (HBsAg) level is pivotal to the diagnosis of HBV infection. In this study, we describe multidimensional conductive nanofilm (MCNF)-based field-effect transistor (FET) aptasensor for HBsAg detection. The MCNF, composed of vertically oriented carboxylic polypyrrole nanowires (CPPyNW) and graphene
The results suggest that perforating arteries arising from the distal M1 segment are related to infarcts involving the upper part of pyramidal tract, while those from proximal segment are related to lower lesions.
Embolic cerebral infarction due to cardiac amyloidosis is rare. We report two patients with amyloidosis who developed cerebral infarcts. These embolic infarcts were probably related to cardiac involvement of amyloidosis, which was based on results of myocardial biopsy (Patient 1), and kidney biopsy and characteristic echocardiographic features including granular sparkling, restrictive cardiomyopathy and the presence of mural thrombus (Patient 2). Diffuse amyloid infiltration of the heart may hav
본 연구에서는 항공사 객실승무원의 직무스트레스 요인이 직무만족, 조직몰입, 이직의도와의 인과관계를 살펴보고 직무스트레스가 직무만족과 조직몰입, 이직의도에 어떠한 영향을 미치는가를 분석하여 항공사 객실승무원들의 직무만족과 조직몰입을 증가시킬 수 있는 방안과 이직의도를 줄이는 방안을 모색하는데 연구의 목적이 있다. 본 연구의 표본 추출은 항공사 객실승무원을 대상으로 하여 215부의 설문지를 배포해서 198부의 설문지를 회수하여 실증분석에 이용하였으며, 통계분석방법은 Spsswin 12.0과 AMOS 5.0 통계패키지를 이용하였다. 분석결과 첫째, 항공사 객실승무원의 직무스트레스는 직무만족에 부(-) 영향을 주었으며, 직무만족은 조직몰입에 긍정적인 영향을 미치는 것으로 나타났다. 둘째, 항공사 객실승무원의 직무스트레스는 조직몰입에 유의적인 영향을 주지 않는 것으로 나타났다. 본 연구에서는 항공사 경영자들은 객실승무원들의 이직을 방지하기 위해서는 승무원들의 직무 관련 스트레스를 해소시킬 수
BACKGROUND: A substantial number of acute stroke patients do not respond immediately to aggressive intra-arterial (IA) recanalization therapy. The factors and outcomes associated with timing of recanalization after IA thrombolysis, however, have not yet been determined. METHODS: Factors and outcomes in 75 acute ischemic stroke patients treated with IA urokinase (± intravenous tissue plasminogen activator) within 6 h of onset were retrospectively assessed. Immediate recanalization (IR) was assess
Since the release of first Korean Clinical Practice Guideline of Stroke in 2009, many important new evidences have emerged in the field of thrombolytic therapy. Among the recent developments are the extended therapeutic time window of intravenous (IV) tissue plasminogen activator (tPA) up to 4.5 hours after onset, and the efforts for the wider application of IV thrombolysis to patients with minor stroke and elderly patients over 80 years old. Debates about the optimal dose of IV tPA according to
