Abstract:
The present invention relates to a culture medium for the fetus-derived mesenchymal stem cells in amniotic fluid. More particularly, the present invention relates to a composition for improving skin conditions, comprising the culture medium of fetus-derived mesenchymal stem cells in amniotic fluid as an active ingredient, in which the skin conditions to be improved include whitening, wrinkles, skin damages caused by UV rays or skin lifting. Further, the present invention relates to a method for preparing the composition, comprising the steps of culturing the fetus-derived mesenchymal stem cells in amniotic fluid; and collecting the culture medium.
Abstract:
A system for controlling a continuous variable valve lift actuator of a diesel engine and a method thereof stabilize exhaust gas and improve performance by variably controlling lift and timing of intake and exhaust valves based on combustion state and driving purpose. The method may include, recognizing a driving purpose and combustion state by detecting driving conditions, temperature of exhaust gas at predetermined locations on an exhaust pipe, and NOx concentration contained in the exhaust gas, determining target position and timing of intake and exhaust valves by applying the driving purpose and the combustion state to a predetermined map table, controlling position and timing of the intake and exhaust valves by actuating a CVVA, detecting combustion pressure in a combustion chamber, and modifying fuel injection amount according to the combustion pressure.
Abstract:
Erosion of chalcogenides in phase change memories using ovonic threshold switch selectors can be reduced by controlling columnar morphology in electrodes used in the ovonic threshold switch. The columnar morphology may cause cracks to occur which allow etchants used to etch the ovonic threshold switch to sneak through the ovonic threshold switch and to attack chalcogenides, either in the switch or in the memory element. In one embodiment, the electrode may be split into two metal nitride layers separated by an intervening metal layer.
Abstract:
Non-platinum (Pt) electrode catalysts for fuel cells, methods of manufacturing the same, and fuel cells including the non-Pt electrode catalysts. Each of the non-Pt electrode catalysts for fuel cells includes at least palladium (Pd) and iridium (Ir), and further includes a metal, oxide of the metal, or mixture thereof for compensating for the activity of Pd and Ir.

Abstract:
A variable valve actuator presses rocker arms using force transmitted from a drive cam to open/close valves of an engine, and includes a swing arm, which is pivotably coupled to the engine on a first side thereof, and at least two pressing means, which come into contact with the rocker arms on first sides thereof, are pivotably coupled to a second side of a swing arm on second sides thereof, and press the rocker arms when pressed by the drive cam. Thereby, the variable valve actuator can adjust a lift time and a lift distance of each valve without changing positions of the drive cams and the camshaft, and more easily adjust the lift time of each valve, and have very excellent applicability to the engine due to simple internal configuration.
Abstract:
Provided is a front-side filter which can be easily attached to a cover of a display device, but is difficult to detach from the cover even after long term use and further provided is a PDP device including the same filter. The front-side filter includes a filter base having at least one function among a near-infrared ray shielding function, and a neon light shielding function, and an electromagnetic wave shielding function; and an antireflective layer with an edge pattern, formed on a side of the filter base in such a way that the entire edge portion or a part of the edge portion of the filter base is exposed through the edge pattern to provide a fixing means formed in the edge pattern. The plasma display panel device includes a case, a cover for covering an upper surface of the case, a driving circuit board enclosed by the case, a panel assembly disposed on the driving circuit board and enclosed by the case, and a front-side filter including a filter base having at least one function among a near-infrared ray shielding function, and a neon light shielding function, and an electromagnetic wave shielding function; and an antireflective layer with an edge pattern, formed on a side of the filter base in such a way that the entire edge portion or part of the edge portion of the filter base is exposed through the edge pattern to provide a fixing means formed in the edge pattern.
Abstract:
Polishing pads are provided that include a substrate for a polishing pad and a plurality of spaced apart members on the substrate and protruding from the substrate. The plurality of members include at least one abrasive layer and at least one chemical additive layer. Related methods of fabricating polishing pads are also provided herein.
Abstract:
A heater cartridge and a molding apparatus using the heater cartridge are provided. The molding apparatus includes a mold comprising at least one cartridge channel and a heater cartridge inserted to the cartridge channel, the heater cartridge comprising a main body casing, a plurality of heating sectors dividing an inside of the main body casing, and a heating part provided to at least one of the heating sectors to heat a predetermined area of the mold. The heater cartridge and molding apparatus having same provide uniform heating to enhance thermal efficiency and the quality of a product.
