    Abstract: The present invention relates to a Yagi antenna and a wireless power transmission apparatus comprising the same, and the Yagi antenna includes a wireless power transmitting coil and first and second slabs made of a metamaterial having a CHDR structure in which cube-shaped resonators are arranged at a predetermined interval. The first slab is positioned at a rear side of the power transmitting coil and serves as a reflector that reflects an electromagnetic wave generated at the power transmitting coil, and the second slab is positioned between the power transmitting coil and a power receiving coil and serves as a super lens that focuses the electromagnetic wave generated at the power transmitting coil. The wireless power transmission apparatus improves efficiency of wireless power transmitted to the power receiving coil by using the Yagi antenna.

    Abstract: The present invention relates to a pharmaceutical composition including a CDK inhibitor and an ID2 activator for the prevention or treatment of bladder cancer, wherein based on the finding that: among CDK1-TFCP2L1 pathway targets associated with urothelial differentiation in bladder cancer cells, ID2 is a factor significantly correlating with the tumor grade of bladder cancer; an ID2 activator exhibits a therapeutic effect on bladder cancer; and the combined administration of CDK1 inhibitor and ID2 activator induces apoptosis of bladder cancer cells and significantly suppresses the invasiveness of cancer cells, compared to administration thereof alone, thereby exhibiting a therapeutic effect of remarkably suppressing the size and progression of bladder cancer, a composition comprising a CDK inhibitor and an ID2 activator and a method for combined administration thereof are provided as novel therapeutic means for the prevention or treatment of bladder cancer.
