Abstract: Disclosed is a wood flooring containing laminated wood and high-density fiberboard using a symmetric structure and a process for manufacturing the same. The wood flooring includes a high-density fiberboard core layer and an upper laminated wood layer and lower laminated wood or veneer layer symmetrically stacked about the high-density fiberboard core layer to achieve a stable structure, and the lower laminated wood or veneer layer has a density of 100±30% of that of the upper laminated wood layer to keep the balance therebetween. With this configuration it is possible to completely eliminate deformation problems caused by variation of environmental conditions such as temperature, humidity, etc., and to impart the natural texture of raw lumber and high durability to the flooring surface.

Abstract: Disclosed herein is a low-priced flooring comprising a transfer-printed high-density fiberboard (HDF). According to the flooring, an aqueous primer layer is formed on a high-density fiberboard as a core layer and transfer printing is performed on the surface of the primer layer to form a printed layer so that the background fiber pattern of the high-density fiberboard is covered, the adhesion of the core layer to the printed layer is enhanced, and the natural beauty of wood is faithfully imparted to the surface of the flooring.

Abstract: This invention is about a novel Biomolecule Transducton Motif (BTM), Sim-2 peptide, which has a potential to transduce many biological response modifiers effectively into the cytoplasm, intracellular organelles or nucleus of prokaryotic or eukaryotic cells in vivo and in vitro, and the related technological methods using Sim-2 BTM. This Sim-2 BTM can be used for Drug Delivery System, development of new recombinant protein vaccines or DNA/RNA vaccines, gene and protein therapy, production of pharmacologically or medicinally useful proteins or pharmacomedicinal drug therapy.

Abstract: Provided are an apparatus and method of operating a multi-changer of an optical disc player which restricts an initial operation of the multi-changer of the optical disc by referring to a disc chucking and tray open/close states. According to the method, it is determined whether a type of a disc, which is currently mounted in the disc mounting unit, has been determined before, if a tray open or close key is inputted. If it is determined that the type of the disc has not been determined before, the tray is opened or closed. Then, if the tray is closed, the type of the disc is determined after chucking the disc which is currently mounted in the disc mounting unit. According to the method, it is possible to stabilize a player by restricting an initiating operation of the multi-changer of the optical disc, which occurs needlessly due to a tray open/close key, when a disc is not yet chucked.

Abstract: This invention relates to microwell array compositions which are coated with one or more thin film coatings. The invention includes the process of fabricating and using thin film coated microwell arrays.

Abstract: An apparatus and a method of reducing a program selection time in an optical disc multi-changer by determining whether a disc is mounted on a disc mounting unit before it is determined whether the disc is chucked and a type of the disc is discriminated. The method of operating the optical disc multi-changer having a tray with disc mounting units, includes receiving a signal to determine whether a disc is mounted on a current disc mounting unit of the disc mounting units, outputting a command signal to move to a next disc mounting unit of the disc mounting units where the received signal indicates that no disc is mounted on the current disc mounting unit, and receiving a program selection signal where the received signal is received from all disc mounting units. Accordingly, it is possible to reduce a program selection time by determining whether the disc is mounted on the disc mounting unit before the disc chucking and discrimination of the type of the disc are performed.

Abstract: This invention is about a novel Biomolecule Transduction Motif (BTM), Mph-1 peptide, which has a potential to transduce many biological response modifiers effectively into the cytoplasm, intracellular organelles or nucleus of prokaryotic or eukaryotic cells in vivo and in vitro, and the related technological methods using Mph-1 BTM. This Mph-1 BTM can be used for Durg Delivery System, development of new recombinant protein vaccines or DNA/RNA vaccines, gene and protein theraphy, production of pharmacologically or medicinally useful proteins or pharmacomedicinal drug therapy.

Abstract: A multidirectional fatigue damage indicator is disclosed. The fatigue damage indicator is composed of a series of fatigue fuse elements welded to a semicircular assembly frames. The fuse elements have the same fatigue lifetime in each row but have different lifetime from row to row so that it may enable one to monitor the progress of fatigue damage of the structure. A series of fatigue fuse elements are welded to a semicircular assembly frame in circumferential direction and additionally in radial direction. The arrangement in circumferential direction is to cover the changing characteristics of the principal stress directions while that in radial direction is to monitor the actual progress of fatigue damage under combined cyclic loads by watching the sequential fracture of the fuse elements.

Abstract: The power steering system for a vehicle includes a steering wheel, a torsion bar fixed to the steering wheel to rotate therewith, a hydraulic control unit for controlling hydraulic pressure generating from an oil pump in accordance with the rotation of the torsion bar, the hydraulic control unit being mounted around the torsion bar, and a power cylinder separated from the torsion bar and receiving the hydraulic pressure from the hydraulic control unit, the power cylinder having a piston meshed with a sector gear which is connected with a pitman arm.
