Abstract: A light detection and ranging (lidar) device includes: a lower base; an upper base; a laser emitting unit for emitting a laser in a form of a point light source; a nodding mirror for transforming the laser in the form of the point light source to a line beam pattern which is perpendicular to the lower base, wherein the nodding mirror reflects the laser emitted from the laser emitting unit; a polygonal mirror for transforming the line beam pattern to a plane beam pattern and receiving a laser reflected from an object; and a sensor unit for receiving the laser reflected from the object via the polygonal mirror.

Abstract: Disclosed are an apparatus for distributing power of an electric vehicle and a method thereof capable of optimally improving the energy consumption efficiency of the electric vehicle by predicting a vehicle speed for a predetermined time using a learned vehicle speed prediction model, determining wheel power based on the vehicle speed, and distributing the wheel power to a front wheel drive motor and a rear wheel drive motor. The apparatus includes a storage that stores a vehicle speed prediction model in which learning is completed, and a controller that predicts a vehicle speed for a preset time using the vehicle speed prediction model, determines wheel power based on the vehicle speed, and distributes the wheel power to a front wheel drive motor and a rear wheel drive motor.

Abstract: The present invention relates to sesterterpene compounds, to the precursors thereof that are hydrolysable in a living body, or to the pharmaceutically acceptable salts thereof, and also relates to the prevention and treatment efficacy of the sesterterpene compounds with respect to non-insulin dependent diabetes mellitus, diabetic complications (renal failure and foot ulcers caused by diabetes), alcoholic, non-alcoholic, and viral fatty liver diseases, obesity, hyperlipidemia, atherosclerosis, cardiovascular diseases such as atherosclerotic stroke, and cerebropathies (Parkinsonism, schizophrenia and Alzheimer's disease). In addition, the present invention relates to compositions for functional foods, functional beverages, functional cosmetics, and functional feed.
