Abstract: Disclosed herein is a method for manufacturing an implant that is to be surgically inserted in vivo, such as in an artificial knee or artificial hip. According to the method, the porous layer contains pores that have a vertically curved shape with a radius of 100 to 300 ?m, thus allowing a bond to grow into the pores to enhance bond adhesion, and an interconnection space is formed between turning points in adjacent unit base layers to increase the ratio of interconnection between pores, whereby bones are allowed to grow into the pores to increase bone adhesion.

Abstract: The present invention relates to an implant which is surgically inserted in vivo such as an artificial knee joint or artificial hip joint. More particularly, the present invention relates to an implant for in-vivo insertion, wherein the porosity of a porous coating layer formed on the surface of the implant, thus increasing the bone adhesion of the implant into pores, the adhesivity between the implant and the porous coating layer and the adhesivity between particles in the porous coating layer, wherein vertically-curved pores each having a radius of 100˜300 ?m are formed in the porous coating layer to increase the adhesivity of the implant to the bone growing into the pores, thus increasing bone adhesion, and wherein the ratio of interconnected pores in the porous coating layer is increased, and thus bones growing into the pores are interconnected, thereby increasing the adhesivity between the implant and the bones.

Abstract: Disclosed is a method for minimizing interference between RFID readers built in a mobile terminal, it is possible to minimize interference between readers by assigning an operating time specific to the mobile terminal at a specific point of time of a cycle of a mobile communication network signal according to an identity number of a mobile terminal, even when several readers are scattered in a predetermined area and they try to detect one tag at the same time.
