A method of constructing surface element layers for improving boundary shape of a hexahedral mesh used in finite element analysis comprises constructing a core mesh by superimposing a regular grid on a region to be meshed and removing external elements and external nodes of the region to be meshed; amending the core mesh to have a boundary shape similar to that of the region to be meshed by repositioning nodes on the boundary of the core mesh; constructing imaginary thin surface element layers on a boundary surface of the amended core mesh; and performing a mesh smoothing on the imaginary thin surface element layers.

A structurally improved rail-type device for mechanically splicing optical fibers while reducing the splicing loss is disclosed. The above splicing device not only has a cladding clamp with a seesaw structure thereby easily splicing the optical fibers, it also separately moves the covers relative to the body to easily perform the tuning operation. Due to coating clamp's protrusions and body's slots engaging with each other, the coating clamp exclusively vertically move relative to the body and prevent the optical fibers from being axially thrust. The splicing device further seperately clamps the coating and cladding parts of the optical fibers, thereby preventing the spliced fibers from breaking due to tensile or torsional force. The sliding motion of the covers relative to the body is achieved by the rails of the covers and rail grooves of the body.

Disclosed is a cleanable and reusable body fluid-absorbing fabric pad to move moisture including sweat and urine away from the skin of a wearer, the body fluid-absorbing fabric pad including, a diffusive fabric layer coming into contact with the skin of the wearer to remove moisture from the skin, an absorbent non-woven layer coming into contact with the diffusive fabric layer, the absorbent non-woven layer comprising at least 5 wt % of a superabsorbent fiber to remove moisture transported from the diffusive fabric layer, and a waterproof film coming into contact with the absorbent non-woven layer and exhibiting waterproofing properties and breathability. The absorbent non-woven layer is formed by needle-punching or thermally bonding superabsorbent fibers, polyethylene/polypropylene bi-component fibers and rayon fibers, wherein the diffusive fabric layer, the absorbent non-woven layer and the waterproof film are stacked and sewed to form the body fluid-absorbing fabric pad. The body fluid-absorbing fabric pad can utilize constituent fabrics having a multiple sublayer structure of the absorbent layer to increase diffusion rate of moisture from the skin of the wearer.

The present invention relates to a novel yeast strain, Eballistra lineata CM602 (KCTC 10945BP) and a phytase produced by the strain. The phytase is thermo- and pH-stable, and also shows a superior enzyme activity at a body temperature of a domestic animal, thus being useful as an additive of forage which may increase the utilization of organic phosphorus. Further, Eballistra lineata CM602 (KCTC 10945BP) strain may be used for a mass-production of enzyme by maximizing biosynthesis of phytase by means of gene recombination techniques, fermentation and optimization.

Disclosed is a method for making a woven or knitted fabric with an excellent water transition ability, involving the steps of fabricating a woven or knitted fabric having a double weave structure by use of a polyethyleneterephthalate (PET) filament for one surface of said fabric and a divided PET/nylon-conjugated fiber for the other surface of said fabric, and subjecting said fabric to a weight loss finishing process. Since the fabric has a void size difference between the surfaces thereof in accordance with the weight loss finishing process, it can externally discharge, at a high velocity, moisture absorbed therein.
