Abstract: The nail art device having a control unit; a holder; a display panel that displays a predetermined selected pattern through the control of the control unit; and a UV irradiation unit that irradiates the display panel with UV rays is provided. When a finger, to the nail of which polish having a UV-reactive component has been applied, is placed in the holder, the polish applied to the nail reacts with the UV rays which are transmitted through the display panel where the selected pattern is displayed to form a nail pattern.

Abstract: The nail art device having a control unit, a holder, and a display panel that contains nanomagnetic particles and displays a magnetic pattern by arranging nanomagnetic particles controlled by the control unit is provided. When a finger, to the nail of which polish having a metallic component has been applied, is placed in the holder, the polish applied to the nail reacts with the magnetism of the magnetic pattern displayed on the display panel to form a nail pattern.

Abstract: Disclosed is a tooth whitening apparatus including: a mouthpiece to which a gel for applying hydrogen peroxide is applied; a lamp unit disposed at an inner tip of a grip case to whiten teeth by using light; a secondary battery disposed on a lower side of a PCB control board inside the grip case; a vibration device disposed at an upper side of the grip case to be operated by an on-off switch; and a USB port charging unit disposed at a rear side of the grip case to charge the secondary battery.

Abstract: A mobile communication terminal and method for proving a substitute image are provided, which automatically searches a substitute image suitable to a video call and transmits the substitute image to the opposite party. A user's image is automatically recorded during a video call, and tagged with information related to the time and situation of the recording, such as location information and time information. The tagged image is stored as a substitute image. When transmission of a substitute image is set while a video call is performed, a substitute image having situation information consistent with or similar to a corresponding situation is searched and then transmitted to the opposite party. Therefore, when a mobile communication terminal performs a video call in various situations, a substitute image suitable to a corresponding situation can be provided to an opposite terminal.

Abstract: A polyethylene resin composition comprises a base resin containing a polyethylene resin alone or an admixture of a polyamide resin and a polyethylene resin, a polyacrylate copolymer obtained by absorbing an acrylate monomer, a functional monomer which is any one selected from an acrylic acid, a methacrylic acid, and a mixture of an acrylic acid and a methacrylic acid, and a polymerization initiator into the base resin, followed by polymerization; and a maleic anhydride introduced in the base resin, wherein the polyacrylate copolymer of 1.1 to 96.6 parts by weight is dispersed in the base resin of 100 parts by weight.

Abstract: The present invention relates to a polypropylene-based composite composition which is directly paintable without treatment of a primer comprised of chlorinated polyolefins. According to the present invention, the polypropylene-based composite composition comprises 30 to 70 weight percent, based on total weight of said polypropylene-based composite composition, of a polypropylene-based resin; 10 to 20 weight percent, based on total weight of said polypropylene-based composite composition, of a polyolefin based thermoplastic elastomer; 10 to 30 weight percent, based on total weight of said polypropylene-based composite composition, of a mineral filler; and 10 to 20 weight percent, based on total weight of said polypropylene-based composite composition, of an acrylate functional polymer additive.

Abstract: Disclosed herein is a polyolefin-based thermoplastic polymer composition, in which an acrylate copolymer phase obtained by absorbing an alkyl acrylate monomer, an alkyl methacrylate monomer, a polar group-containing acrylate monomer and a polymerization initiator into a polyolefin matrix and then polymerizing the monomers is dispersed in a polyolefin phase. The thermoplastic polymer composition has excellent surface polarity leading to excellent paint adhesion.

Abstract: The present invention relates to a polyolefin-based resin composition for the calendering process which can be directly printed without applying an adhesive since the surface printability is improved. The present invention provides a polyolefin-based resin composition for the calendering process comprising: 3 to 95 weight percent, based on total weight of said polyolefin-based resin composition, of a high impact polyolefin resin; 1 to 50 weight percent, based on total weight of said polyolefin-based resin composition, of an acrylate functional polymer; 1 to 30 weight percent, based on total weight of said polyolefin-based resin composition, of a polyolefin-based thermoplastic elastomer; 1 to 50 weight percent, based on total weight of said polyolefin-based resin composition, of a mineral filler; and 0.1 to 5.0 weight percent, based on total weight of said polyolefin-based resin composition, of a lubricant.
