Abstract: Proposed is a composite film including a first film layer attached to an upper surface of a steel member, a second film layer positioned on the first film layer, and a mesh film layer positioned on the second film layer and having a mesh structure. A portion of the mesh film layer is embedded into the second film layer during a heat compression process when the composite film is manufactured. The composite film improves the water resistance, chemical resistance, abrasion resistance, and durability of a steel member when the steel member is coated with the composite film.

Abstract: Disclosed is a biological measurement device. The biological measurement device includes a first plate including a first transmission window; an electrode structure disposed on the first plate and spaced apart from the first window; a chamber plate disposed over the electrode structure and the first plate, the chamber plate including for exposing a portion of the electrode structure and the first transmission window; a second plate disposed over the chamber plate, the second plate including a second transmission window facing the first transmission window; a light emitting unit positioned either over the second transmission window and emitting light toward the second transmission window; and a light receiving unit disposed under the first transmission window and being configured to receive the light which the light emitting unit supplies to pass through the blood sample.

Abstract: The present invention relates to a composition for preventing or treating liver cancer containing ginsenoside F2 as an active ingredient. Specifically, the composition according to the present invention kills liver cancer cells, specifically inhibits the formation of liver cancer, and reduces the expression of alanine aminotransferase (ALT) or aspartate aminotransferase (AST), without affecting normal hepatocytes, and thus can be usefully used as a therapeutic agent for liver cancer.

Abstract: A computer system having an internal graphics module; an external graphics module detachably connected to the computer system; and a power controller turning on/off power supplied to the internal graphics module depending on a connection state of the external graphics module. With this configuration, the computer system and the method of controlling the system prevent wasteful power consumption.

Abstract: Disclosed is an automatic control system using a power line communication method. The automatic control system comprises an operating module having an operating program; a power line communication module connected to the operating module; and an automatic control module connected to the power line communication module through a power line and adapted to control external appliances by means of a control signal supplied thereto from the operating module. The operating module receives and processes a signal from external appliances through the automatic control module, or generate an appliance control signal for transmission to the automatic control module, thereby implementing a low-speed power line communication together with the automatic control module through the power line communication module. The automatic control system may remotely control or monitor various electric appliances through an Internet network using a conventional power line.
