A method for manufacturing a vehicle wheel includes: a casting process of manufacturing the wheel in a one-piece body having a forming end and a temporary flange protruding at inner and outer sides of the wheel, respectively, wherein the one-piece body further includes a resonance chamber forming groove; a primary shape machining process of forming a stepped part at an outer circumferential side of the resonance chamber forming groove; a flow forming process of bending the forming end to be seated on the stepped part; a friction stir welding process of integrally bonding a portion where the forming end and the stepped part are in close contact with each other; a fine machining process of removing the temporary flange; and a sound-absorbing hole machining process of forming a sound-absorbing hole for communicating between the resonance chamber and an interior space of a tire in the forming end.

The present invention provides a gene including an M13 p5 expressing cassette, which includes a promoter, a ribosome binding site (RBS) and a protein 5 (p5) coding region, wherein at least one base of sequences between the RBS and the p5 coding region is mutated. Using this gene may increase production of single-stranded DNA.

A water cooling apparatus for cooling centrifugal casting equipment that includes an upper mold and a lower mold rotating together includes a rotating shaft in which a first cooling passage is formed and to which a nozzle is provided at an end portion of the rotating shaft, and a collecting portion which surrounds a side surface of the lower mold and is installed apart from the lower mold. The lower mold is connected to the rotating shaft and includes a chamber separated from a mold space formed between the upper and lower molds in order to store cooling water injected to the nozzle. The lower mold includes at least one second cooling passage extended from the chamber toward an outer circumference surface direction, and the collecting portion receives the cooling water discharged through the second cooling passage.
