Journal ArticleDOI
Fiber optic Fabry–Perot pressure sensor based on lensed fiber and polymeric diaphragm
TL;DR: In this article, a novel optical fiber-based Fabry-Perot pressure sensor fabricated with a lensed fiber and a polymeric diaphragm is proposed for application in the medical field.
Journal ArticleDOI
Novel mode converter based on hollow optical fiber for Gigabit LAN communication
Sang-Soo Choi,Kyunghwan Oh,Woojin Shin,Chang-Ju Park,U.C. Paek,Keun Joo Park,Yun Chur Chung,Young Ho Kim,Y.G. Lee +8 more
TL;DR: In this article, a ring-shaped mode converter based on a hollow optical fiber is proposed to reduce the differential modal delay penalty in optical transmission over multimode fibers (MMFs), which is composed of serially concatenated concentric segments of a single-mode, hollow, and multimode optical fiber.
Journal ArticleDOI
Anti-Reflux Ureteral Stent with Polymeric Flap Valve Using Three-Dimensional Printing: An In Vitro Study
Chang-Ju Park,Hyeon Woo Kim,Sangdo Jeong,Seungwan Seo,Yangkyu Park,Hong Sang Moon,Jong-Hyun Lee +6 more
TL;DR: In vitro studies showed that the anti-reflux ureteral stent effectively prevented backward flow with a negligible reduction in forward flow and was successfully designed and fabricated using a 3D printer.
Journal ArticleDOI
Microelectrical Impedance Spectroscopy for the Differentiation between Normal and Cancerous Human Urothelial Cell Lines: Real-Time Electrical Impedance Measurement at an Optimal Frequency
TL;DR: The μEIS-RT can discriminate SV-HUC-1 and TCCSUP cells by measuring the impedance at the optimal frequency determined by the μEIR, which maximized the average difference of the amplitude and phase angle between the two cell lines.
Journal ArticleDOI
Evaluation of a Polymeric Flap Valve-Attached Ureteral Stent for Preventing Vesicoureteral Reflux in Elevated Intravesical Pressure Conditions: A Pilot Study Using a Porcine Model.
Hyeon Woo Kim,Chang-Ju Park,Seungwan Seo,Yangkyu Park,Jeong Zoo Lee,Dong Gil Shin,Hong Sang Moon,Jong-Hyun Lee +7 more
TL;DR: In this paper, a polymeric flap valve-attached ureteral stent was used to prevent vesicouretersal reflux (VUR) in an animal model.
