  • Patent number: 10835758
    Abstract: Disclosed is an organic light-emitting device for light therapy for wound healing and cell proliferation, including: a substrate; an organic light-emitting device layer formed on the substrate and emitting red light; and a heat sink layer formed on the organic light-emitting device layer, which forms a red organic light-emitting device emitting red light in a stacking structure including a heat sink layer to generate light in a form of a planar light source which can be driven at a low temperature, thereby solving a problem of a burn and can perform light therapy through close contact with the skin.

  • Patent number: 10715797
    Abstract: The present invention relates to a device for testing an angle of view of a camera. The present invention may comprise: a first light source which is arranged to face an image sensor, and has a first width and a second width longer than the first width; and a second light source and a third light source which are disposed on both sides of the image sensor in the direction of the first width, respectively. The present invention can inhibit an interference of the light source or a bracket supporting the light source by reducing the number of light sources. In addition, since it is possible to measure the angle of view of a camera by reducing the light sources, the present invention can reduce the manufacturing costs of a device for testing an angle of view of a camera.

  • Publication number: 20090209020
    Abstract: The present invention relates to a method of preparing a collagen matrix with increased porosity and tensile strength by using mechanical stimulation system. More specifically, in the present invention, the cell-populated gel is being cultured under the condition that the physical forces is loaded for causing the matrix to move periodically and discontinuously. Resulting collagen matrix can be used for preparing an artificial skin or organs. Furthermore, this collagen matrix can be used as fillers for esthetic or therapeutic purposes.

  • Publication number: 20070128136
    Abstract: The present invention relates to a melanin biosynthesis inhibitor containing terrein compound as an effective ingredient. The terrein compound can be easily separated from Penicillium sp KCTC 26245, a fungal strain inhabited in domestic soil. It does not directly inhibit tyrosinase but inhibits the expression of MITF (microphthalmia-associated transcription factor) by activating ERK (extracellular signal-regulated kinase) in melanin chromatocytes to give whitening effect. So, the melanin biosynthesis inhibiting effect of the compound is much greater than that of any other conventional inhibitors, and further the effect can be raised when the compound is used together with other inhibitors, owing to their different mechanisms. Thus, the compound of the present invention can be effectively used as a skin trouble treating agent, a skin whitening agent and a browning inhibitor.
