Abstract:
PURPOSE: A nonallergenic urushiol derivative is provided to maintain a structural basic skeleton of amphiphilic urushiol having a catechol structure that is a strong antioxidation active site and an oil soluble long side chain in the same molecule. CONSTITUTION: A nonallergenic urushiol derivative is a catechol type urushiol derivative represented by chemical formula 1. A veratro urushiol derivative is used in synthesis of the nonallergenic urushiol derivative and has a structure represented by chemical formula 2. In chemical formulas, R is CnH2n+1, wherein n is 6-9 or 16-19 chain type saturated hydrocarbon.
Abstract:
A method for preparing veratrol type and catechol type urushiol derivatives, and the their uses are provided to obtain an excellent antioxidizing activity. The veratrol type and catechol type urushiol derivatives prepared do not induce allergy with maintaining the structural basic frame of urushiol. Preferably the urushiol derivatives have a side chain comprising a saturated hydrocarbon.

Abstract:
PURPOSE: A lip area determining method for lip reading in a mobile device is provided to horizontally cluster the lips of speakers and separate the lips from shadows under the lips by a threshold Y axis coordinate value. CONSTITUTION: First candidate objects are generated from lip images using clustering(S2000). Second candidate objects are extracted using a gray average value of each first candidate object. Third candidate objects are eliminated from the second candidate objects using a reliability function(S3000). The clustering is performed again by using a threshold Y axis coordinate value. Fourth candidate objects are extracted(S4000). A fifth candidate object is determined from the fourth candidate objects using the reliability function(S5000).
