7This study was performed to develop thin layer drying equations for low temperature. Thin layer drying tests of short grain rough rice were conducted at three low temperature levels of 15, 25, 35℃ and two relative humidity levels of 30, 50%, respectively. The measured moisture ratios were fitted to the selected four drying models (Page, Thompson, Simplified diffusion and Lewis model) using stepwise multiple regression analysis. The overall drying rate increased as the drying air temperature was
This study was performed to determine drying equations of sarcodon aspratus. Drying tests for sarcodon aspratus were conducted in an experimental dryer equiped with an air conditioning unit. The drying tests were performed at three air temperatures of 30℃, 40℃ and 50℃, and two relative humidities of 30% and 50% . Measured moisture ratio data were fitted with the selected four drying models(Page, Thompson, Lewis and simplified diffusion models) using stepwise multiple regression analysis. When th
Desorption equilibrium moisture contents of oak mushroom were measured by the static method using salt solutions at four temperature levels of 35℃, 45℃, 55℃ and 65℃ and five relative humidity levels in the range from 11.0% to 90.8%. EMC data were fitted to the modified Henderson, Chung-Pfost, modified Halsey and modified Oswin models using nonlinear regression analysis.Drying tests for oak mushroom were conducted in an experimental dryer equipped with air conditioning unit. The drying test were
본 연구에서는 인체에너지 수확에 있어서 에너지수확의 효율뿐 아니라 의복의 착용 쾌적성도 중요하다는 측면에서, 에너지의 효율과 착용 쾌적성을 모두만족시킬 수 있는 디자인을 도출하고자 하였다. 선행연구에서 관절운동 시 의복의 밀착도(4 levels)와 디자인(3 types)에 따른 압전에너지 수확의 에너지 효율을 분석하였다. 그 결과 압전에너지 수확의 효율은 의복의 밀착도가 높아질수록, 압전소자의 굴곡이 극대화될수록 높아짐을 알 수 있었다. 에너지 하베스팅 의류는 에너지 수확의 기능뿐만 아니라 의복의 착용감도매우 중요하다. 이에 본 연구에서는 의복의 쾌적성을평가하기 위해 “pressure sensation level”, “activity sensation level”, “thermal sensation level”의 주관적평가를 실시하여 에너지 수확의 효율과 의복의 착용감을 동시에 만족시킬 수 있는 디자인을 찾고자 하였다. 그 결과, 의복의 밀착도(4 levels) 중 세 번째로 밀착도
Mitochondria play an essential role in cancer initiation and progression. Research in the past decades suggested a close relation between mitochondrial dysfunction and cancer, including non-small cell lung cancer (NSCLC). In addition, mitochondrial dysfunction causes excess levels of reactive oxygen species (ROS) generation and induces mitophagy for removing damaged mitochondrial. Therefore, the induction of mitophagy against abnormal mitochondria in cancer cells is expected to be a therapeutic
Extrachromosomal DNA (ecDNA) has appeared as a key driver of oncogene amplification, tumor heterogeneity, and therapeutic resistance, thereby reshaping the paradigm of precision oncology—particularly in metastatic and treatment-refractory cancers. However, the clinical translation of ecDNA-based discoveries into scalable therapeutic applications remains limited. This study introduces an integrated, empirically validated precision oncology platform that combines ecDNA biomarker profiling, artific
본 연구에서는 뇌혈류 신호를 측정할 수 있는 시변자계 기반의 비접촉식 직물센서를 설계하여 뇌혈류 신호 검출및 감성평가의 가능성을 탐색하고자 하였다. 직물센서는 40 denier의 은사를 30합사 한 후 컴퓨터 기계 자수하여 코일형 센서로 구현하였다. 뇌혈류 측정 실험을 위해 코일형 센서를 경동맥 부위에 부착하고, ECG (Electrocardiogram) 전극과 RSP (Respiration) 측정 벨트를 부착 및 착용하도록 하였으며, 동시에 초음파 진단기기를 사용해 도플러 초음파 검사(Doppler Ultrasonography)를 수행하여 혈류 속도를 측정하였다. 피험자에게 Meta Quest 2를 착용시키고, 실험을 위해 조작된 영상 시각 자극을 보여주면서 혈류 신호를 측정한 후 시각 자극에 대한 감성평가 설문지를 작성하도록 하였다. 측정 결과, 도플러 초음파 검사를 통해 측정된 혈류 속도 신호에 변화가 생길 때 직물센서로 측정한신호도 함께 변화하는 것으로 나타났다. 이를 통해
