Abstract: Provided are a feed additive composition and a feed composition including the same. The feed additive composition includes ursolic acid and/or maslinic acid, and the feed composition includes the feed additive composition.

Abstract: The method for treating wastewater includes a first flocculation-and-sedimentation process and a second flocculation-and-sedimentation process, wherein the first flocculation-and-sedimentation process include: passing wastewater through a first flocculation reaction tank; passing the first treated water through a third flocculation reaction tank; passing the third treated water through a fourth flocculation reaction tank; and passing the fourth treated water through a first sedimentation tank to generate fifth treated water and sludge, and the second flocculation-and-sedimentation process include: passing the fifth treated water through a fifth flocculation reaction tank to generate sixth treated water; passing the sixth treated water through a sixth flocculation reaction tank to generate sixth treated water; passing the sixth treated water through a seventh flocculation reaction tank to generate eighth treated water; and passing the eighth treated water through a second sedimentation tank to generate ninth t

Abstract: Disclosed are a method and apparatus for reusing wastewater. The method for reusing wastewater disclosed herein includes: generating a mixed wastewater by mixing multiple types of wastewater (S20); performing a first purification by passing the mixed wastewater through a flocculation-sedimentation unit (S40); performing a second purification by passing an effluent of the flocculation-sedimentation unit through a membrane bioreactor (MBR) (S60); performing a third purification by passing an effluent of the MBR through a reverse-osmosis membrane unit (S80); and reusing an effluent of the reverse-osmosis membrane unit as cooling water or industrial water (S100).

Abstract: A multifunctional push-pull mop includes a base plate, a support member, and an elastic member. A user can bring the base plate to which a cleaning cloth is attached into close contact with a floor, a wall, a ceiling, or the like, using a small force, and when the user moves the base plate to which the cleaning cloth is attached from a boundary portion between a floor and a wall or between a wall and a ceiling to the floor, wall, or ceiling, the base plate can be rotated by the elastic restoration force of the elastic member to instantly come into close contact with the floor, wall, or ceiling, thereby allowing the user to conveniently move the base plate from the boundary portion of the floor, the wall, the ceiling, or the like, without detaching the base plate therefrom.

Abstract: A multi-processor system and method are provided. A multi-processor network management apparatus in a broadband wireless communication system includes a main processor and at least one primary sub processor. The main processor controls an overall operation of the multi-processor network management apparatus and provides environment information to other processors. The primary sub processor performs processor initialization using the environment information received from the main processor.
