Abstract: Disclosed is a light emitting device, a method of manufacturing the same, a light emitting device package, and a lighting system. The light emitting device may include a first conductive semiconductor layer including first conductive impurities, a second conductive semiconductor layer including second conductive impurities different from the first conductive impurities, an active layer between the first conductive semiconductor layer and the second conductive semiconductor layer, and an AlInN-based semiconductor layer interposed between the active layer and the second conductive semiconductor layer while making contact with both of the active layer and the second conductive semiconductor and including the second conductive impurities.

Abstract: A light emitting device according to the embodiment includes a substrate; a buffer layer over the substrate; an electrode including a perforation pattern through top and bottom surfaces of the electrode over the buffer layer; a first semiconductor layer over the electrode; an active layer over the first semiconductor layer; and a second semiconductor layer over the active layer. The first semiconductor layer extends onto a top surface of the perforation pattern by passing through the perforation pattern while making contact with the buffer layer.

Abstract: Disclosed herein is a method for producing a transparent or opaque flooring sheet or a flooring using a styrene-butadiene copolymer resin (as a thermoplastic elastomer) by calendering. The flooring causes no problems associated with environmental hormones, and generates no halogen gases or endocrine disruptors, such as dioxin, during incineration. Further, the flooring can be regenerated and reused at any time, and exhibits superior stability upon installation and mounting and excellent elastic restoration after application of stress due to inherent flexibility of rubber.

Abstract: The present invention relates to the system, method and program for the pharmacokinetic parameter prediction of peptide sequence by the mathematical model. The present invention is comprising the steps of acquiring a variety of peptide sequence having specific features by the experimental technique; acquiring, on the basis of the sequence, a variety of peptide sequences lacking the specific features; storing the acquired peptide sequences as each set respectively, followed by randomly extracting peptide sequences in the constant ratio to divide into a training set and a test set of mathematical model; allowing individual peptide sequence descriptor values and an activity value; training the set of training peptide by mathematical model; predicting pharmacokinetic parameter of the set of test peptide by the trained mathematical model; and validating the trained mathematical model.
