Abstract: The present invention relates to a method for preparing carbon nanotubes, the method including: preparing a support including AlO(OH) by primary heat treatment of Al(OH)3; preparing an active carrier by supporting a mixture including a main catalyst precursor and a cocatalyst precursor on the support; drying the active carrier through multi-stage drying including vacuum drying; preparing a supported catalyst by secondary heat treatment of the dried active support; and preparing carbon nanotubes in the presence of the supported catalyst, and the carbon nanotubes prepared by the method as described above can remarkably improve conductivity.

Abstract: An apparatus and method for setting a region of interest of a vehicle that is being driven is provided. The apparatus includes an image capturing unit configured to capture a front image of the vehicle that is being driven, a memory configured to store a program for setting the region of interest of the vehicle that is being driven, and a processor. The processor obtains a current position of the vehicle and lane information corresponding to the current position based on the front image captured by the image capturing unit by executing the program, and sets the region of interest needed for recognition of a signal light based on the obtained lane information, and the processor sets a region including a lane corresponding to another vehicle driving in the same direction as the vehicle that is being driven in the front image as the region of interest.

Abstract: An apparatus and method for generating a font by using a glyph is provided. The method includes: generating a first basic glyph as a basic shape of a character or a grapheme; generating second through ath (wherein a is an integer greater than or equal to 2) basic glyphs to which at least one of a transversely expanded shape of the basic shape and a longitudinally expanded shape of the basic shape is applied; performing an interpolation operation by using at least two of the first through ath basic glyphs to generate an interpolation glyph having a different shape from the first through ath basic glyphs; and generating a font by using the first through ath basic glyphs and the interpolation glyph.

Abstract: The present invention relates to a hair extension in which false hair 10 has strands of hair of a predetermined length of which the top ends are bonded to each other to form an attachment portion 12, two bundles of false hair 10 being interconnected via a connection string 40, wherein the connection string 40 is tied with a separate rubber string 30. The hair extension of the present invention decreases the thickness of the joint between the human hair and the false hair to achieve aesthetic enhancement, and prevents the length of the hair extensions from being shortened while applying the hair extensions so as to provide hair extensions with the desired length. The present invention minimizes the changes in posture of a worker applying hair extensions, thereby reducing fatigue of the worker and shortening the working time.

Abstract: A system for managing production of semiconductors that can improve or maximize productivity. In an embodiment, the system comprises: a host computer for outputting control signals to control semiconductor production processes; semiconductor production apparatuses each of which performs a corresponding semiconductor production process using the control signals output from the host computer; a conveyor for conveying a wafer carrier; and a conveyor monitoring apparatus for monitoring the conveyance of the wafer carrier, determining if the conveyor is delayed for more than the predetermined time, and displaying an error status to a remote operator.

Abstract: The present invention relates to a parking brake system using a tapered roller in ramp-typed brake caliper for vehicles, in which because a tapered roller in ramp-typed caliper that generates parking brake force through axial force in the operation of a parking brake system is mounted, stable axial force is generated and relatively large contact areas are obtained by axial surface contacts by tapered rollers, so that it does not require forging with very high precision that is required for ball in ramp-typed ramps with point contact, thus the manufacturing process comes In be easy,
