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 three-dimensional studio system includes a booth including camera modules each including a camera and a driving device and sensor modules; a database configured to store camera setting data and driving setting data; a booth control unit configured to transfer a photographed image of the camera to an external image processing device, and provide a camera control signal and a driving control signal to the camera and the driving device, respectively; and a statistical analysis unit configured to back up the camera setting data and the driving setting data in the database by reflecting a rendering correction value.

Abstract: An advertising system and an advertising method using a 3D model. The advertising system includes a contents manager configured to provide contents where a 3D model is disposed on a background on which an advertisement is represented in at least a partial area; a 3D model analysis unit configured to analyze the 3D model, and generate an analysis information about the 3D model; an advertisement providing unit configured to provide an advertisement information by using at least one of a background type information for the background and the analysis information about the 3D model; and a background providing unit configured to provide the background including the advertisement information for representing the advertisement, to the contents manager.
