Abstract: The present invention relates to a motor driving control system and a control method thereof. The purpose of the present invention is to provide a motor driving control system and a control method thereof, which may change electric current limiting logic, which is applied to a BLDC motor for a cooling fan, in response to an operating speed of the motor to stably protect the motor from an overload in a low-speed driving state as well as an overload in a high-speed driving state.

Abstract: A semiconductor device includes a lower electrode; a supporter supporting an outer wall of the lower electrode; a dielectric layer formed on the lower electrode and the supporter; an upper electrode on the dielectric layer; a first interfacial layer disposed between the lower electrode and the dielectric layer and selectively formed on a surface of the lower electrode among the lower electrode and the supporter; and a second interfacial layer disposed between the dielectric layer and the upper electrode, wherein the first interfacial layer is a stack of a metal oxide contacting the lower electrode and a metal nitride contacting the dielectric layer.

Abstract: Provided is a natural complex preservative agent for a grain or grain-based product. The preservative agent contains 50 wt % or greater of a Cordyceps extract and a broccoli extract, wherein the Cordyceps extract and broccoli extract are conjugated.

Abstract: The present invention relates to a method for cultivating vegetable worms having a function of a natural preserved agent and freshness keeping agent. The method comprises obtaining a mycelium by inoculating a cordyceps militaris or a cordyceps nutans to a liquid medium, a solid medium or a worm body; and forming a fruit body from the mycelium by cultivating a solid medium or a worm body.
