20120010697 | HEART VALVE PROSTHESIS USING DIFFERENT TYPES OF LIVING TISSUE AND METHOD OF FABRICATING THE SAME - A heart valve prosthesis and a method of fabricating the same. The heart valve prosthesis uses a leaflet of pig pericardium or a leaflet of cattle pericardium, which has a suitable thickness according to the size of the valve, and a stent. The heart valve prosthesis is fabricated by placing a valve body over a Dacron body, binding the valve body to the Dacron body using stitching fiber, rolling the Dacron body into a cylindrical form such that the valve body is located inside, binding opposite edges of the Dacron body to each other using stitching fiber, and inserting the resultant structure into a stent, which is knitted using a shape memory alloy wire. The heart valve prosthesis is friendly to and is not rejected by human tissue, is free from deformation, and can be implanted using a non-invasive manner without incising the chest wall of a patient. | 01-12-2012 |
20130284639 | HYDROCRACKING PROCESS OF HEAVY HYDROCARBON DISTILLATES USING SUPERCRITICAL SOLVENT - Specific embodiments of the present invention provide a hydrocracking process for converting low value-added heavy hydrocarbon distillates into high value-added hydrocarbon distillates using a supercritical solvent as a medium. | 10-31-2013 |
20140377814 | Method For The Fixation Or Conversion Of High-Pressure Carbon Dioxide Using Barophilic Sulfur-Oxidizing Chemolithoautotrophs - The present invention relates to a method for biologically treating carbon dioxide using the sulfur-oxidizing chemolithoautotroph | 12-25-2014 |
20150218459 | Simultaneous Pretreatment Method Of Heavy Hydrocarbon Distillate And Lignocellulosic Biomass Using Solvent - A method of reforming a heavy hydrocarbon distillate, which includes treating a heavy hydrocarbon distillate and a lignocellulosic biomass with a solvent, is provided. | 08-06-2015 |
20150283535 | METHOD FOR PREPARING HOLLOW CARBON STRUCTURE USING CRACKING REACTION OF HEAVY HYDROCARBON FRACTION - The present invention relates to a method of preparing a hollow carbon structure. The method includes a step of calcining a solid component separated after a cracking reaction of a heavy hydrocarbon fraction; and a step of performing an acid treatment or base treatment on the solid component calcined in the above-described step. | 10-08-2015 |
20150293106 | DIAROMATIC AMINO ACID SUBSTRATE FOR CATHEPSIN DETECTION - The present invention relates to a diaromatic amino acid substrate for cathepsin detection. When the substrate used for cathepsin detection is a polymer resulting from the binding of a protease-preferred amino acid and quencher to a diaromatic amino acid, cathepsin can be detected sensitively and accurately by fluorescence because cathepsin causes the protease-preferred amino acid and quencher to dissociate from the diaromatic amino acid, and fluorescence is recovered during this time. | 10-15-2015 |
20150360199 | PROCESS FOR PREPARING CARBON DIOXIDE ADSORBENT AND CARBON DIOXIDE CAPTURE MODULE CONTAINING THE ADSORBENT - The present invention relates to a method of preparing a carbon dioxide adsorbent and a carbon dioxide capture module including the adsorbent prepared thereby. | 12-17-2015 |
20160039690 | APPARATUS AND METHOD FOR TREATING BALLAST WATER - The present invention relates to an apparatus and a method for treating ballast water, and an exemplary embodiment of the present invention provides a ballast water treatment apparatus including: a tank; a spray nozzle which supplies ballast water in the form of droplets into the tank; and a gas circulation unit which supplies inert gas to the spray nozzle, and sucks inert gas that is not dissolved in the ballast water in the tank. | 02-11-2016 |
20160042347 | METHOD, SERVER, AND SYSTEM FOR PROCESSING A TRANSPORTATION FARE - A method, a server, and a system includes a central server configured to compare an authorization result of a fare payment means upon boarding a transportation means with an authorization result of the fare payment means upon leaving the transportation means, determine whether to update at least one of a boarding terminal and a departure terminal based on the comparison result, and transmit update information to at least one of the boarding terminal and the departure terminal based on the determination result. The boarding terminal performs an authorization process of the fare payment means upon boarding if a network connection between the central server and the boarding terminal is unstable, and the departure terminal performs an authorization process of the fare payment means upon leaving if a network connection between the central server and the departure terminal is unstable. | 02-11-2016 |
