Abstract: The present invention relates to a toe pad with excellent permeability and adhesion, and to a toe pad, of which toe insertion incision parts into which an index toe, a middle toe, and a ring toe can be inserted are formed on a pad main body, wherein in the toe insertion incision part, horizontal incision parts are formed symmetrically to each other in a vertical direction and a vertical incision part is formed to vertically connect one sides of the horizontal incision parts such that a toe spacer is formed. The horizontal incision part has both ends incised in a round shape in an outward direction in which the toe spacer is formed so as to form toe upper and lower support plates and a toe side support plate supporting toes. The toe pad with excellent permeability and adhesion according to the present invention includes a toe insertion incision part which can form toe upper and lower support plates and a side support plates by an ergonomic arcuate design on a toe pad having a toe spacer. Accordingly, when the toe pad is worn, the support plates are in close contact with toes according to a curvature of the toes itself such that toes are naturally spaced apart from each other. As a result, the toe pad can induce excellent permeability while minimizing the feeling of foreign substances. In addition, the toe pad has excellent adhesion with toes such that the original shape of the pad can be maintained for a long time. In addition, the generation of wrinkles and damage to the shape of the pad, caused by friction during walking, can be prevented such that the toe pad can provide wearing comfort and prevent separation of toes in advance.

Abstract: A piston structure of a fluid extrusion cylinder according to one embodiment of the present invention, which is mounted on an upper portion and a lower portion of a mold having a polishing hole and allows a fluid object to reciprocate in the polishing hole of the mold so that the surface is processed, comprises a piston head part coming in tight contact with an inner periphery of the fluid extrusion cylinder to form a closed space for accommodating the fluid object, a piston rod part reciprocating by a drive cylinder driven by hydraulic pressure or pneumatic pressure, and a clamp part mediating between the piston head part and the piston rod part so that the piston head part and the piston rod part are mutually fixed or separated, wherein the piston head part may have a flat surface facing the closed space. The piston structure of the fluid extrusion cylinder can prevent the inflow of the fluid object into the piston of the fluid extrusion cylinder during molding.

Abstract: The present invention relates to a novel peptide derived from a flounder shell hydrolysate having an inhibitory effect on collagenase activity and a use thereof. Since the novel peptide, according to the present invention, can effectively inhibit collagenase activity, a composition containing the same as an active ingredient can be usefully used for wrinkle alleviation. Thus, the flounder shell hydrolyzate of the present invention can be widely used as a material in various fields such as the pharmaceutical industry, food industry and cosmetics industry. In particular, since the novel peptide of the present invention is based on the amino acid sequence of a peptide derived from a natural product and has stability without cytotoxicity, the composition of the present invention containing the same as an active ingredient is safe for long-term use.
