Abstract: Disclosed is an artificial implant comprising: a silicone shell; and a filler filling the interior of the shell, wherein at least a portion of the shell is a rupture-prevention part comprising two or more silicone layers and one or more reinforcing material layers interposed therebetween.

Abstract: A method for forming a coating film of a material for enhancing bioactivity, such as a water-soluble vitamin, on a surface of a dental implant, and a dental implant produced by the method, in order to overcome the limitations in improving osseointegration capability, which result from existing physical surface treatments, such as RBM and SLA surface treatments. The methods enable the SLA-pretreated implant surface to have blood affinity and an enhanced bioactive function, thereby providing a method for producing a dental implant which has excellent biocompatibility and high osseointegration capability after the implant procedure and thus has enhanced bioactivity, and a dental implant produced by the method. The surface of the dental implant, from which organic pollutants have been removed, are coated with a bioactive material, thereby enhancing blood affinity and bioactivity of the implant and thus improving initial osseointegration capability of the implant.

Abstract: A mobile communication terminal having QWERTY keys and a method for outputting Dual Tone Multi-Frequency (DTMF) signals thereof are disclosed. The user inputs information including alphabetic characters that is requested by a directory system, while viewing the alphabetic characters marked on the QWERTY keys. The mobile communication terminal outputs DTMF signals of symbols marked on the input QWERTY keys identical to the DTMF signals of the corresponding symbols of keys arrayed in a conventional 3×4 key array format. The alphabetic keys of the QWERTY keys output DTMF signals identical to those of the keys of the 3×4 array format in an alphabet input mode. Therefore, the user can easily input information requested by the directory system while viewing the symbols marked on the QWERTY keys, without requiring the user to memorize the array of alphabetic characters of the 3×4 key array format.
