  • Publication number: 20150152218
    Abstract: There is provided a method of preparation for a biodegradable co-polyester, the method including: forming an oligomer through a primary esterification reaction between a hydroxy group of an aliphatic dihydroxy compound and a carboxylic group of an aliphatic dicarboxylic acid compound; performing a secondary esterification reaction between the formed oligomer and an aromatic dicarboxylic acid compound; and performing a polycondensation reaction in a vacuum, in which sequentially divided addition of the aromatic dicarboxylic acid compound is performed and the weight ratio of the aromatic dicarboxylic acid compound with respect to the oligomer for each time of the sequentially divided addition is from 2:8 to 5:5. The method efficiently increases a solubility of aromatic dicarboxylic acid, thereby increasing a reaction rate and reducing a side reaction.

  • Publication number: 20150146928
    Abstract: An apparatus and method for tracing a motion of an object using high-resolution image data and low-resolution depth data acquired by a hybrid camera in a motion analysis system used for tracking a motion of a human being. The apparatus includes a data collecting part, a data fusion part, a data partitioning part, a correspondence point tracking part, and a joint tracking part. Accordingly, it is possible to precisely track a motion of the object by fusing the high-resolution image data and the low-resolution depth data, which are acquired by the hybrid camera.

  • Publication number: 20150119481
    Abstract: There are provided a resin composition for foaming including a biodegradable resin and a foamed article made thereof. The resin composition for foaming according to the present invention includes an ethylene-vinyl acetate resin, a biodegradable polyester resin containing a monomer of a double bond compound, a cross-linking agent, a co-crosslinking agent, a filler, and a foaming agent. In the resin composition, the double bond in the biodegradable polyester resin can be chemically cross-linked to the ethylene-vinyl acetate resin by a cross-linking agent, so that a compatibility with the ethylene-vinyl acetate resin can be improved, processability (mold releasability) during a mixing and melting process can be improved, and a foaming property and a mechanical property of a foamed article can be remarkably improved.

  • Publication number: 20140288261
    Abstract: A catalyst used to manufacture a biodegradable polyester resin, in particular, an organic titanium catalyst which does not contain a heavy-metal component, and a method of manufacturing a polyester resin using the same. Accordingly, the method of manufacturing a polyester resin can be useful in attaining desired physical properties without using a catalyst harmful to environments and a human body. The biodegradable resin, which can be safely used in the field of applications in which the use of harmful components is a sensitive issue without using the components harmful to environments and a human body during the manufacture of a resin, can be prepared.
