Abstract: An apparatus and a method for modeling a controller of a CAN bus are provided. The apparatus for modeling a controller of a CAN bus includes a modeling device for modeling a communication unit of a controller of the CAN bus and for evaluating the communication unit in a configuration of a CAN bus topology of the CAN bus. The modeling device includes an evaluation item determiner for determining the evaluation item used for simulating the configuration of the CAN bus topology, a factor determiner for determining factors that affect the evaluation result of the determined evaluation items, and a circuit design device for designing the circuit configured to include the determined factors.

Abstract: The present invention relates to a cosmetic composition for skin whitening comprising a small molecule-peptide conjugate. More specifically, it concerns the cosmetic composition for skin whitening comprising Caffeic acid-LG-NH2 or Coumaric acid-LG-NH2 as an active ingredient, which inhibits tyrosinase activity and melanin production, thereby showing an excellent skin whitening effect, and having no side effects to the skin by using a peptide component.

Abstract: An amine oxide type surfactant, which has excellent compatibility with an anionic or non-ionic surfactant having excellent detergency and shows excellent detergency and softening effect, is represented by the following formula 1: wherein R1 and R2 are the same or different, and each independently represents a C8˜C22 linear or branched alkyl or alkenyl group; A represents a C1˜C4 alkyl, alkenyl or hydroxyalkyl group; X represents OH, a C1˜C4 alkyl, hydroxyalkyl, (CH2CH2O)nH, (CHCH3CH2O)nH or a combination of (CH2CH2O)nH and (CHCH3CH2O)nH; and n is a number of 1˜30.
