Abstract: Disclosed herein is an apparatus and method for detecting an emotional change through facial expression analysis. The apparatus for detecting an emotional change through facial expression analysis includes a memory having at least one program recorded thereon, and a processor configured to execute the program, wherein the program includes a camera image acquisition unit configured to acquire a moving image including at least one person, a preprocessing unit configured to extract a face image of a user from the moving image and preprocess the extracted face image, a facial expression analysis unit configured to extract a facial expression vector from the face image of the user and cumulatively store the facial expression vector, and an emotional change analysis unit configured to detect a temporal location of a sudden emotional change by analyzing an emotion signal extracted based on cumulatively stored facial expression vector values.

Abstract: A display device includes a substrate and a plurality of unit pixels disposed on the substrate. Each unit pixel includes a plurality of sub-pixels, a plurality of light sensing pixels, and a plurality of partition wall members. Each of the sub-pixels includes a light emitting element that emits light and a light emitting area from which the light is emitted. Each of the light sensing pixels includes a light receiving element that outputs a sensing signal corresponding to the light and a light receiving area that receives the light. In a plan view, each of the partition wall members surrounds the corresponding light receiving area and overlaps at least some of the sub-pixels.

Abstract: Disclosed herein is nanoemulsion prepared by emulsifying main metabolites of ginseng saponin obtained by conversion of glucose, i.e. compound K (20-O-?-D-glucopyranosyl-20(S)-protopanaxadiol), ginsenoside F1 (20-O-?-D-glucopyranosyl-20(S)-protopanaxatriol) and compound Y (20-O-[?-L-arabinopyranosyl(1?6)-?-D-glucopyranosyl]-20(S)-protopanaxadiol); and admixture thereof, in fine emulsion or liposome with dermotropic emulsifier by nano-emulsification; and having enhanced skin penetration, so to be effective in promoting proliferation of fibroblast and biosynthesis of collagen.

Abstract: A percutaneous releasing material and agent having characteristics that include a high stability of an active agent in the formulation, a high topical absorption rate, decreased irritation on the skin, and an increased tactile comfort. The percutaneous releasing material incorporates an external application agent composition that is prepared by using nanometer-sized polymer particles, i.e., particles having a size or diameter between approximately 1 nm and approximately 500 nm, and more preferably having a size between about 30 nm and about 150 nm. Further, the percutaneous releasing material and agent according to the present invention incorporate polymer particles that preferably contain a physiologically active agent that more readily penetrates through the stratum corneum to the upper layer of the dermis, whereby the physiologically active agent is effused into the skin while staying in the upper layer of dermis.
