Abstract: Provided is a method for preparing a recycled ABS resin, and the method for preparing a recycled ABS resin includes: preparing an extrusion feed including an acrylonitrile butadiene styrene (ABS) base resin including polyurethane, a metal carboxylic acid salt, and a polyhydric alcohol; and supplying the extrusion feed to an extruder to perform a depolymerization reaction of the polyurethane and extruding the extrusion feed.

Abstract: A method for preparing a recycled polymer is provided. The method includes: bringing a recovered polymer containing an additive into contact with an impregnation solvent in an impregnation tank to obtain a slurry containing a swollen polymer and an eluate; separating the slurry into a solid mixture containing the swollen polymer and a liquid mixture containing the eluate in a solid-liquid separator; and obtaining a recycled polymer from the solid mixture and recovering the additive from the liquid mixture, wherein the impregnation solvent is a mixed solvent of two or more solvents.

Abstract: A hinge device of a portable terminal having a foldable structure, according to the present invention, comprises: a housing positioned between one-end portions of a first body and a second body; a first hinge blade and a second hinge blade fixed to the first body and the second body and rotationally supported on the housing to perform rotation movement as much as a predetermined angle between an ‘unfolded position’ at which the first body and the second body are placed on the same horizontal line and a ‘folded position’ at which the first body and the second body are facing and in contact with each other; and a slide member for interlocking the first hinge blade and the second hinge blade to perform a relative motion, wherein a first inclined guide protrusion and a second inclined guide protrusion are formed on bottom surfaces of the first hinge blade and the second hinge blade, a first inclined guide groove and a second inclined guide groove are formed on a top surface of the slide member in correspondence t

Abstract: A muscular strength assisting apparatus includes a muscular strength assisting portion that assists a user's muscular strength and a first connecting link including one side connected to one side of the muscular strength assisting portion and an opposite side rotatable relative to a shoulder of the user about a first rotation axis. The muscular strength assisting portion includes an upper arm module that assists muscular strength of an upper arm of the user and a link assembly including one side connected to one side of the upper arm module to be rotatable about a second rotation axis non-parallel to the first rotation axis and an opposite side disposed adjacent to a portion of a body of the user to be supported on the user.

Abstract: The present invention relates to a pharmaceutical composition, including inhibitors for expression or activity of TIP41 protein, for prevention and treatment of cancer. When the liver cancer cell lines, showing resistance to TRAIL, are treated with TIP41 siRNA and TRAIL, apoptosis is induced in cancer cell. The same effect is found in cases of lung cancer and colon cancer with resistance against TRAIL. Moreover, this induction of apoptosis by TIP41 siRNA and TRAIL was confirmed in tumor xenograft, which was injected with Huh7 liver cancer cells and then was subjected to TIP41 siRNA transfection and TRAIL treatment. In addition, it was confirmed through animal experiments in which the tumor size has reduced and apoptosis was induced by treatment with TIP41 siRNA and TRAIL. Of note, MKK7/JNK pathway was confirmed to mediate the apoptosis induced by the application of TIP41 siRNA and TRAIL. The apoptosis were verified to be caused by the activation of MKK7/JNK signaling pathway.

Abstract: The present invention relates to a diagnostic marker containing ZNF312b gene and the fragment thereof, a diagnostic method for stomach cancer and a screening method for stomach cancer inducers or inhibitors using the same. ZNF312b gene expression is specifically increased in stomach cancer. And the over-expression or the under-expression of the gene affects activation or inhibition of cell proliferation and tumor formation of a stomach cancer cell line and cell proliferation signal transduction system as well to induce stomach cancer at last. Therefore, ZNF312b marker gene can be effectively used for diagnosis of stomach cancer, construction of a stomach cancer animal model, prevention and treatment of stomach cancer and development of a stomach cancer specific anticancer agent.
