Abstract: The method and system for converging a 5th-generation (5G) communication system for supporting higher data rates beyond a 4th-generation (4G) system with a technology for internet of things (IoT) are provided. The method includes intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The system includes a power amplification device capable of minimizing the effect of envelope impedance. The power amplification device may be incorporated in a terminal and a base station.

Abstract: A method of coating surfaces of various body-implantable materials with control-releasable nitrogen monoxide using a catecholamine, more particularly, technology of preparing a coating film containing a diazeniumdiolate functional group on a surface of a material to be coated using a catecholamine, is provided. The coating film prepared by the method has advantages in that nitrogen monoxide can be stably supplied under an in vivo environment, and can be suitably used in a living body without causing cytotoxicity. Therefore, among the materials having a coating film formed on a surface thereof, the body-implantable material is especially expected to be widely used for medical and health applications including treatment of ischemic disorders such as arteriosclerosis through controlled release of nitrogen monoxide, regulation of penile erections, antibacterial and antiviral effects, and wound healing.
