Abstract: A display device includes a first communication unit connected to one or more peripheral devices, a second communication unit that communicates with a remote controller, and a processor. If the processor is initialized in response to a power-on instruction through the second communication unit, the processor verifies whether a first peripheral device, which is selected as a source device that provides at least one source of video and audio signals, among the one or more peripheral devices is powered on within a first threshold time. If the first peripheral device is not powered on within the first threshold time, the processor transmits a power-on request for allowing the remote controller to power on the first peripheral device, to the remote controller through the second communication unit.

Abstract: Embodiments relate to an evaluation device for a skin texture based on a skin blob, which includes a skin blob determining unit configured to determine a skin blob in a skin image, a skin blob information measuring unit configured to measure at least one of a gross area, an average area, a number, a gross border length, an average border length, a direction and an angle of the skin blob in the skin image, and a skin texture evaluating unit configured to evaluate a skin texture of the skin image based on the measurement result; and an evaluation method thereof.

Abstract: Disclosed is a novel use of a composition comprising as an active ingredient a Scutellaria alpina extract. A composition according to the present description shows hair follicle cell proliferation or hair growth effect by means of comprising a Scutellaria alpina extract. Therefore, due to said effect, the Scutellaria alpina extract has hair loss prevention or hair growth stimulation effect.

Abstract: Disclosed is a novel use of a composition comprising as an active ingredient an Artemisia umbelliformis extract. A composition according to the present description shows hair follicle cell proliferation or hair growth effect by means of comprising an Artemisia umbelliformis extract. Therefore, due to said effect, the Artemisia umbelliformis extract has hair loss prevention or hair growth stimulation effect.

Abstract: The present invention relates to a wrinkle measurement apparatus and a wrinkle measurement method. The wrinkle measurement apparatus according to one embodiment of the present invention comprises: a surface direction compression part including first and second contact parts arranged at a preset gap while coming into close contact with the skin, so as to compress the skin in the direction of the surface thereof; and a wrinkle measuring part for measuring skin wrinkles in at least two states among pre-compression, mid-compression and post-compression.

Abstract: The present invention relates to a cosmetic composition for skin moisturization that contains minerals and a quinoa extract.

Abstract: Disclosed is a composition for promoting a production of hyaluronic acid containing at least one of kaempferol and quercetin. Kaempferol and quercetin of the invention increase an expression of a hyaluronic acid synthase (HAS) gene existing in a skin cell line of human epidermis, thereby promoting a production of hyaluronic acid in the human cell. Accordingly, the composition containing at least one of kaempferol and quercetin according to the invention can be usefully used as a cosmetic composition for increasing skin elasticity and preventing skin dryness or aging, or a pharmaceutical composition for treating or preventing a degenerative arthritis.

Abstract: The present invention provides hydroxamic acid derivatives which have anti-aging efficacy and a method for preparation thereof. It is further provided skin-care external compositions for preventing skin aging, containing the hydroxamic acid derivatives represented by the formula (I) as an active ingredient.

Abstract: The present invention provides hydroxamic acid derivatives represented by the following formula (I), having anti-aging efficacy and a method for preparation thereof: wherein, R1 is herein, R5 and R6 each independently represents a hydrogen atom, a C1-C10 alkyl group or a C3-C6 cyclic alkyl group; R2 is CONH, NHCO, CONR7 or NR7CO, herein, R7 represents a C1-C10 alkyl group; R3 is —(CH)n—, herein, n=0 or 1; and R4 is a hydrogen atom or a C1-C10 alkyl group. Further, the present invention provides skin-care external compositions for preventing skin aging, containing said hydroxamic acid derivatives represented by the formula (I) as an active ingredient.

Abstract: The present invention provides hydroxy pyranone derivatives and a method for preparing the hydroxy pyranone derivatives. The hydroxy pyranone derivatives of the present invention are significantly effective in promoting the biosynthesis of collagen and in inhibiting the activity of collagenase, i.e. an enzyme for decomposing collagen, to have anti-wrinkle efficacy, and can be incorporated into medicines or external applications for lessening skin-wrinkles.
