Abstract:
A method for displaying a peroral phage is provided to identify a peptide showing an optimum absorption efficiency passing through small intestine mucosa at highest frequency. And a peroral administration system in which the identified peptide is introduced is provided to increase the absorption efficiency of a protein drug into a bio-membrane significantly, thereby enlarging the usability of the protein drug. A method for displaying a peroral phage comprises the steps of: (a) forming a phage-peptide library; (b) perorally injecting the library into a rat; (c) blood-irrigating the rat; (d) after taking organs from the rat and taking a tissue sample therefrom, washing and homogenizing the sample, neutralizing it and then titrating it; (e) quantifying phage from the sample; and (f) after titrating the separated phage to separate phage DNA therefrom, analyzing a sequence of the DNA to identify a peptide functional group and is characterized in that the steps (b) to (e) are repeated more than 3 times to perform a biopanning, the phage passing through small intestine mucosa after the biopanning is identified at various tissues and organs such as liver, lung, heat, spleen and blood, and an acid elution step after the homogenization step(d) is added to identify an organ targeting peptide specifically bound to a specific tissue after passing through the small intestine mucosa. A peptide identified by the method and inducing the absorption promotion of small intestinal epithelium includes an amino acid sequence of CSKSSDYQC. A peroral administration system is characterized in that the peptide inducing the absorption promotion of small intestinal epithelium is introduced into a protein-based drug.

Abstract:
A method for aligning nanostructures, such as nanowires, by using a self-assemblage process is provided to allow mass production of nanowires of which surface comprises an oxide, and to realize various surface nanostructures. A method for aligning nanowires of which surface comprises an oxide comprises the steps of: patterning a molecular membrane having the opposite charge to an oxide on the surface of a solid; dipping the patterned solid into a solution in which nanowires are dissolved; allowing the nanowires to be adsorbed onto a region where the molecular membrane is not patterned; and dissolving and removing the molecular membrane. The molecular membrane comprises at least one hydrophobic molecule selected from octadecytrichlorosilane(OTS), octadecyltrimethoxysilane(OTMS) and octadecytriethoxysilane(OTE).

Abstract:
A stroke booster device for an actuator is provided to apply enough lateral displacement on a beam member even in case that lateral displacement required for the beam member is bigger than the maximum stroke of the actuator. A stroke booster device for an actuator includes a boosting member(2) and a frame(3). The boosting member is a vertical beam, of which upper part is rotatably connected to a beam(10) and lower part is connected to the actuator for receiving lateral displacement from the actuator. Both ends of the folded frame are fixed. The frame bent in an L-type is rotatably hinged with the boosting member at a bent point(4). The stroke booster device boosts the lateral displacement and applies the boosted lateral displacement to the beam.
