20110221348SYSTEM AND METHOD FOR CONTROLLING LIGHTING - Disclosed herein are a system and a method for controlling lighting. In the lighting control system, one or more lighting devices are installed in a separate area within a building and a remote controller generates a scheduling data by setting lighting scenes at each time and controls the lighting of the corresponding lighting device via a short range wireless communication. In addition, the remote controller transmits the scheduling data to a remote server through a gateway and when the remote controller is not normally operated, the remote server controls the lighting device according to the scheduling data through the gateway.09-15-2011

20100047308Production methods of virus inactivated and cell-free body implant - A method is provided for producing a virus-inactivated, acellular implant for the human body, featuring the use of TNBP in combination with a detergent selected from among deoxycholate, SDS, Tween 80, Triton X-100, sodium cholate and combinations thereof for removing cells and viruses simultaneously. Also disclosed are an acellular human body implant produced by the method and a wound healing agent comprising the acellular human body implant.02-25-2010
20100129421COMPOSITION FOR PROMOTING BONE REGENERATION AND RESTORATION - A bone grafting material composite is provided. The bone grafting material composite includes a demineralized bone matrix (DBM) and a carboxymethyl cellulose (CMC)/glycerol gel carrier. Due to the CMC/glycerol gel carrier, the implantation ability thereof is better than that of the DBM. Therefore, the bone grafting material composite can be easily used, so that a curative effect can be greatly improved. In addition, since the CMC/glycerol gel is used as a carrier, the composite with a mobility maintained is washed out by water after surgery, so that the composite can be fixed on a damaged portion of a bone.05-27-2010
20100160467ORGANIC-INORGANIC HYBRID SCAFFOLDS WITH SURFACE-IMMOBILIZED NANO-HYDROXYAPATITE AND PREPARATION METHOD THEREOF - Provided are an organic-inorganic hybrid scaffold with surface-immobilized nano-hydroxyapatite, and a method for the fabrication thereof. The scaffold is fabricated by reacting an acid group present on a surface of nano-hydroxyapatite with a primary amine present on a surface of a polymer support in the presence of EDC (1-ethyl-3-dimethylaminopropyl carbodiimide) to immobilize nano-hydroxyapatite onto the surface of the polymer support. The surface of nano-hydroxyapatite is previously grafted with poly(ethylene glycol methacrylate phosphate) (PolyEGMP) having phosphonic acid functionality or with a polymer having carboxylic acid functionality.06-24-2010
