Abstract: Embodiments of a multi-purpose implant for use in surgery, such as for reconstruction of soft tissues, are disclosed. In some embodiments, the implant includes elastic polymer film made from a suitable biologically compatible polymer. The implant also includes a reinforcement element formed from a polyurethane mesh or other strong and stable woven or unwoven synthetic material. The reinforcement element can be fully enclosed by the film so that only the film comes into contact with the organs and tissues. Anti-adhesive properties or control over implant's integration into a body can be determined by the preset surface structure of the implant, while physical and mechanical properties, such as strength and elasticity of the implant, are obtained by virtue of reinforcement element geometry.

Abstract: Disclosed is a platform for providing users with a variety of contents and information of on-line/off-line interested party using barcode, method for providing contents using the platform, and a billing system and method therefor.

Abstract: Two-dimensional code having superior decoding property making it possible to control the level of error correcting codes, and a method for encoding and decoding the two-dimensional code is provided. The two-dimensional code includes a finding pattern area comprised of finding patterns for discriminating the code area from the whole image, a timing pattern area comprised of timing patterns for checking a position of the data area from the whole code and the position of each cell of the data area, and a data area being inputted with various kinds of data and decoding information.
