Abstract: Disclosed is a positive electrode material for a lithium secondary battery. The positive electrode material includes a positive electrode active material formed of Li—[Mn—Ti]-M-O-based material including a transition metal (M) to enable reversible intercalation and deintercalation of lithium and molybdenum oxide. The positive electrode active material is coated with the molybdenum oxide to form a coating layer on a surface thereof.

Abstract: Disclosed are a pothole sign detection system and method of a road pavement, and a recording medium having recorded thereon a computer readable program for executing the method. The pothole sign detection system includes an electromagnetic wave transmitting unit, an electromagnetic wave receiving unit, an electromagnetic wave receiving unit, a dielectric constant calculation unit, a crack rate diagnosis unit, a pavement layer separation state diagnosis unit, an attenuation calculation unit, a pavement layer inside state diagnosis unit, and a pothole sign detection unit.
