Abstract: A method for treating a cerebrovascular disease according to an embodiment of the present disclosure includes administering a composition comprising at least one of melittin and magnetic iron oxide nanoparticle loaded with melittin as an effective component to a subject in need thereof. A composition according to an embodiment of the present disclosure for preventing, ameliorating, or treating a cerebrovascular disease includes melittin or magnetic iron oxide nanoparticle loaded with melittin as an effective component. The melittin or magnetic iron oxide nanoparticle loaded with melittin not only can reduce the diameter of cerebral arteries, increase the thickness of cerebral arteries, increase the content of elastin and smooth muscles, and reduce the content of abnormal collagen but also has an effect of suppressing the expression of the factors which mediate an inflammatory response.

Abstract: Disclosed herein is an intravascular device for removing thrombosis and recovering a blood flow, wherein the attachment of thrombosis can be facilitated since a plurality of minute protrusions are formed on the surface of the stent structure. The present inventive concept is able to significantly minimize any separation of the thrombosis when the device for removing thrombosis and recovering a blood flow is transferred to the outside of a human body in such a way that a plurality of minute protrusions are formed on the surface of the stent structure, and the attachment of the thrombosis to the stent can be facilitated.

Abstract: Provided is a method for forming a pattern of polyimide that is simpler and is more excellent in the pattern shape and in the dimensional accuracy in comparison with the conventional techniques of patterning polyimide, such as photolithography and laser processing. In a method for forming a micropattern of polyimide, which includes using as polyimide a solvent-soluble polyimide resin composition that is photosensitive and is moldable at a temperature of less than or equal to a glass-transition temperature; patterning the composition using thermal imprinting; and thermally curing the composition, ultraviolet irradiation is performed after the composition is released from a mold after a molding step.

Abstract: A semiconductor light emitting element with a design wavelength of ?, comprising a photonic crystal periodic structure having two structures with different refractive indices at each of one or more interfaces between layers that form the light emitting element. The period a and the radius R that are parameters of each of the one or more periodic structures and the design wavelength ? satisfy Bragg conditions. The ratio (R/a) between the period a and the radius R is a value determined so that a predetermined photonic band gap (PBG) for TE light becomes maximum for each periodic structure. The parameters of each periodic structure are determined so that light extraction efficiency of the entire semiconductor light emitting element with respect to light with the wavelength ? becomes maximum as a result of conducting a simulation analysis with a FDTD method using as variables the depth h of the periodic structure that is of greater than or equal to 0.
