Abstract: An embodiment of the present specification provides a method for preparing a catalyst for preparing a carbon nanotube, comprising: (a) dissolving a main catalyst precursor, a support precursor, a cocatalyst precursor and a precipitation inhibitor in a solvent to prepare a precursor solution; and (b) pyrolyzing the precursor solution by spraying the precursor solution into a reactor, wherein a mole fraction of the precipitation inhibitor to the cocatalyst precursor is 0.1 to 1.5.

Abstract: Provided is a refrigerator including a storeroom, an inner casing including a first plate to define the storeroom, a partition coupled to the first plate to divide the storeroom into multiple storerooms, and a bracket arranged on the first plate to couple the partition to the first plate, wherein the first plate includes a plurality of holes formed at a location corresponding to a location where the bracket is coupled to the first plate.

Abstract: The present invention relates to a use of a biological surfactant as an anti-inflammatory agent and a tissue preservative solution. More particularly, the present invention is directed to an anti-inflammatory agent and a tissue preservative solution comprising a biological surfactant which blocks a reaction of a proinflammatory factor with a receptor by emulsifying the proinflammatory factor.

Abstract: A wing-in-ground (WIG) craft having a streamlined WIG craft body, a main wing mounted on opposite sides of the WIG craft body, a pylon mounted on the WIG craft body or the main wing, and a combined thruster having a primary thruster unit mounted on the pylon, and an auxiliary thruster unit serving as a booster used when the WIG craft takes off from a water surface.

Abstract: The wing structure of a WIG vehicle comprising left and right main wings, left and right downward wings, and a rudder unit. The left and right main wings protrude out from the central portions of left and right sides of the WIG vehicle. The panel of the main wing is flat and tapers successively toward the lateral edge, whereof the cross-section is airfoil-shaped and has the shape of a tadpole. The panel shaped left and right downward wings are connected with both ends of the left and right main wings without a joint and are formed heading downward to suppress vortex and guidance drag generated in both ends of the main wings. The rudder units are mounted on the rear surface of the left and right downward panels with a slight gap in order to compensate asymmetry between left and right lateral ends caused by movement under control of the fuselage driving unit of the WIG vehicle and to turn the fuselage left or right.

Abstract: A body having a fuselage, a wing unit including a main wing, and a propulsion unit including an engine. The wing unit includes a main wing protruding out from the lateral center of the WIG vehicle fuselage, a downward wing which is vertically and downwardly installed on the outer tip of the main wing, and a canard which protrudes out horizontally from the front end of the fuselage, which is in the moving direction of the WIG vehicle from the main wing. The canard includes a horizontal stabilization plate which has a stationary horizontal panel structure, and a variable flap which is installed to face the rear surface of the horizontal stabilization plate. In the lateral cross section shape, the front surface portion including the leading edge is round at a proper thickness to prevent clearance generated by turning of the canard, the trailing edge is sharp and straight, and the thickness of a portion between the thickest portion and rear portion narrows.
