Sung Oh Hwang 교수의 연구실은 심폐소생술(CPR)의 생체역학적 영향과 최적화된 소생 기법에 중점을 두고 있으며, 심장의 혈류 역학적 특성과 소생 시 혈액순환 개선 전략을 실험적·모델 기반으로 연구하고 있습니다. 특히 심실출구부 narrowing 등 심장 구조적 변화가 소생 성과에 미치는 영향을 분석하고 있으며, 이를 바탕으로 소생 기록의 최적화 및 임상 적용 가능성을 탐색하고 있습니다. 또한 생체 신호 분석 및 저전력 신호 처리 기술을 융합한 의료 장치 설계에도 관심을 기울이고 있습니다.

The outflow of the left ventricle is affected during standard CPR, resulting in varying degrees of narrowing in the LVOT and/or the aortic root.
This letter proposes a new distributed arithmetic (DA) algorithm for low-power finite-impulse response (FIR) filter implementation. The characteristic of the proposed algorithm is that the FIR filters using the proposed algorithm do not need to employ two's complement representation in lookup tables as well as multiply-and-accumulation blocks. Thus, the proposed algorithm can minimize the dynamic power consumption of the FIR filters. The experimental results show that the lowpass FIR filter usin
The decreasing effect of wrinkle on the pressure sensitive adhesive hydrogel patches containing ulmi cortex extract and sorbitol as the drug for anti-wrinkle were investigated. In this study, hydrogels were prepared by the crosslinking reaction of acrylic polymers and aluminum ions produced by L(+)-tartaric acid hydrolysis of the dihydroxy aluminum aminoacetates. The inhibition concentration of ulmi cortex extract on the collagenase exhibited at 0.01%. Furthermore, the moisturizing effect of hyd
In a canine model of witnessed VF using a simulated scenario, CPR with three CV ratios, 15:1, 15:2, and 30:2, did not result in any differences in hemodynamics, arterial oxygen profiles, and resuscitation outcome among the three groups. CPR with a CV ratio of 15:1 provided comparable chest compressions and shorter pauses for ventilation between each cycle compared to a CV ratio of 30:2.

Determining the cause of cardiac arrest (CA) and the heart status during CA is crucial for its treatment. Transesophageal echocardiography (TEE) is an imaging method that facilitates close observation of the heart without interfering with cardiopulmonary resuscitation (CPR). Intra-arrest TEE is a point-of-care ultrasound technique that is used during CPR. Intra-arrest TEE is performed to diagnose the cause of CA, determine the presence of cardiac contraction, evaluate the quality of CPR, assist
