Idiopathic pulmonary fibrosis (IPF) is a progressive, eventually fatal disease characterized by of the lung parenchyma and loss function. IPF believed to be caused repetitive alveolar epithelial cell injury dysregulated repair process including uncontrolled proliferation (myo) fibroblasts excessive deposition extracellular matrix proteins in interstitial space; however, pathogenic pathways involved have not been fully elucidated. In this study, we attempted characterize metabolic changes...
We report the thermal and electrical bistable characteristics of ferroelectric poly(vinylidene fluoride-trifluoroethylene) [P(VDF-TrFE) (72∕28mol%)] thin films as a function varying memory device architectures. Rectangular-shaped capacitance-voltage (C-V) hysteresis loops obtained using 100nm P(VDF-TrFE) with metal-ferroelectric-insulator-semiconductor (MFIS) diode architecture were more suitable for distinguishing data-bit state compared symmetrical observed metal-ferroelectric-metal...
An aortoesophageal fistula (AEF) is an extremely rare, potentially fatal condition, and aortic surgery usually performed together with extracorporeal circulation.However, this surgical method has a high rate of complications mortality.This report describes AEF caused by tuberculous esophagitis that was treated successfully using two-stage operation.A 52-yr-old man admitted to the hospital severe hematemesis syncope.Based on computed tomography diagnostic endoscopic findings, he diagnosed...
Abstract In this article, nylon 6,6 (NY66) and glass fiber‐(30 wt%) reinforced NY66 (GFNY66) specimens were immersed in various aqueous calcium chloride (aq. CaCl 2 ) mixture solutions at different thermal conditions for varying intervals of time, analyzed using attenuated total reflection‐infrared (ATR‐IR) spectroscopy, inductively coupled plasma (ICP), energy dispersive X‐ray (EDX), gel permeation chromatography (GPC), mechanical studies. ICP data revealed increasing concentration absorbed...
Several methods for endovascular aortic arch repair have been proposed to reduce the morbidity and mortality associated with conventional open surgery aneurysms. We report our experience aneurysm by a totally technique, that is, "reversed" stent graft technique using branched grafts.
Case ReportThe average age of hemodialysis patients has been increasing, leading to increase in with insufficient vascular resources for dialysis access.The author addressed this issue by correcting completely occluded brachial artery through endarterectomy and angioplasty, enable their utilization as inflow vessels hemodialysis.Although the patient underwent steal syndrome following surgery, peripheral blood flow restored angioplasty endovascular stent insertion, allowing stable maintenance...
A 63-year-old patient was admitted with a sternal fracture and mass.On evaluation, most of the body sternum had been destroyed by tumor.Radical resection performed part major pectoral muscles adherent to tumor also resected.The chest wall defect reconstructed mesh, bone cement, titanium rib plate system.Reconstruction this method seemed be an appropriate procedure prevent instability wall.
In this study, the dipole switching and non-volatile memory functionality of poly(vinylidene fluoride-trifluoroethylene) (PVDF/TrFE)(72/28 mol%) random copolymer ultrathin films were analyzed. PVDF/TrFE(72/28) used as ferroelectric insulator in varying device architectures such metal-ferroelectric polymer-metal (MFM), MF-insulator-semiconductor (MFIS), MIS field-effect transistors (FeFET) examined using different electrical measurements. A maximum data writing speed 1.69 MHz was calculated...
The Korean government established dasiathe Act on Performance Evaluation and Management for National R&D Programspsila in 2005, one year later constructed a master plan, dasiaA Basic Plan the Utilization of performancepsila that focused better diffusing public outcomes. In this study, we propose performance monitoring evaluation system model national program, which is based systematic approach logic has prevalently used planning evaluating programs, to meet purpose law plan as well...
Among the clinical symptoms of coronavirus disease 2019 (COVID-19), acute respiratory dysfunction syndrome (ARDS) is most rapid and fatal form symptoms, since conventional treatment cannot achieve satisfactory results, extracorporeal membrane oxygenation (ECMO) can be tried. We report two cases, one COVID-19 patients who received ECMO for ARDS at Soonchunhyang University Bucheon Hospital long-term but improved without any complications, patient viral myocarditis rapidly deteriorated died....

An aortoesophageal fistula (AEF) is a rare and lethal disorder. However, aortic surgery usually performed with extracorporeal circulation, there high rate of surgical complications mortality. This report describes case AEF caused by radiotherapy for esophageal cancer. A 59-year-old man was treated preoperative chemoradiation, developed tracheoesophageal (TEF) 3 months later (3 cycles cisplatin 5-fluorouracil). He complained hemoptysis hematemesis. Based on computed tomography diagnostic...
Background: Some patients refuse blood transfusions despite the risk of hematological complications, such as anemia and iron deficiency, associated with obstetrics treatments surgery. Therefore, this study aims to investigate effectiveness safety supplementation, a major method bloodless treatment, retrospectively examine clinical characteristics patterns individuals who underwent treatment after obstetrical Methods: We collected medical records consented between September 2001 October 2016,...
A right pleural mass was detected incidentally in a 52-year-old woman and chest computed tomography showed lobulated mass. Thoracoscopic excision performed. Histology solitary fibrous tumor with extensive cystic change. Solitary change is very rare we treated this successfully video-assisted thoracic surgery.
