Gachon University is an academic institute located in South Korea. The current structure of Gachon university is the result of a merger between four existing universities. Gachon University of Medicine and Science and Gachon-gil College merged in 2007, Kyungwon University and Kyungwon College merged in 2007, and Gachon University of Medicine and Science and Kyungwon University merged in 2012. Gachon University has three campuses for undergraduates, the Global Campus located in Seongnam, satellite campuses on Ganghwa Island and in Yeonsu-dong, and the School of Medicine in Guwol-dong, Namdong-gu, Incheon, South Korea. Gachon University signed a strategic partnership with Hawaii Pacific to allow students to study abroad. " Wikipedia.

Source Type

A junctionless field-effect transistor is provided and has an ultra-thin low-crystalline silicon channel. A fabrication method thereof also is provided for enabling greatly improved economics by significantly reducing the process costs while having electrical characteristics similar to those of the one formed on an SOI substrate by source/channel/drain regions formed in a junctionless ultra-thin low-crystalline silicon layer that has lower crystallinity than that of single-crystal silicon and that has a thickness of 20 nm or less on a bulk silicon substrate instead of an expensive SOI substrate.


The present invention provides a transistor and a fabrication method thereof. By a silicon nanowire as a core region being serially wrapped by a germanium channel, a gate insulating film and a gate, the present invention enables to form a potential well for storing holes as a carrier of HHMT in the germanium channel by a valance band energy offset between the silicon core region and the germanium channel, to gain maximum gate controllability to the germanium channel, and to simplify a fabricating process by simultaneously forming the germanium channel and the gate insulating film in one process.

According to the present invention, accurate T2* and vascular images are concurrently acquired by acquiring a T2* image without a flow compensation and a T2* image with a flow compensation and subtracting the two images to reconstitute an image showing the flow phenomenon. Furthermore, an accurate T2* image can be acquired by using the readout gradient without the flow compensation and also the accurate T2* and vascular images can be concurrently acquired. The clinical judgment for blood flow rate of the blood vessel and the clinical judgment for acute stroke can be concurrently made, and so the present invention can be widely utilized in clinical practice.

Images where the vascular walls are automatically divided are obtained by obtaining two MRI images that reflect different properties of the blood vessel and obtaining the difference between the two images. This can image both the vascular inner and the outer walls, thereby obtaining the exact size of the blood vessel, and the thickness between the vascular inner and outer walls. Therefore, it is possible to stably perform the operation using a stent with an accurate size during the stent procedure.

Disclosed is an artificial valved conduit that is a composite valved graft comprising double sewing cuffs, which can be easily used in aortic root replacement. The composite valved graft comprises a valve and a conduit part connected to the valve. The conduit part comprises a sewing cuff positioned on the outer circumference thereof. The sewing cuff comprises a first sewing cuff and a second sewing cuff positioned below the first sewing cuff. Accordingly, a double suture is easily performed, so that it is possible to prevent the loss of blood after a surgery and to reduce surgical time at the same time.


A method of manufacturing a thin film according to an exemplary embodiment of the present invention includes preparing an ink in which nickel oxide nanoparticles are uniformly dispersed, coating the ink on a base layer, and curing the ink to form a thin film including nickel oxide nanoparticles.
