Abstract:
Disclosed is a method for changing emotion of a software robot (sobot) in a sobot terminal. The sobot terminal includes a short-term memory unit and a long-term memory unit. When an emotional change occurs during the operation of the short-term memory unit, the sobot terminal stores a short-term reference emotion value of the corresponding emotion in the long-term reference memory. When the operation time of the long-term memory unit elapses, the sobot terminal resets the long-term reference emotion value using the short-term reference emotion values stored in the long-term memory unit. The sobot terminal can change the emotion of the sobot more naturally through the above process.

Abstract:
Disclosed is a method of producing teicoplanin. The method includes purifying teicoplanin from a culture broth, obtained by culturing microorganisms capable of producing teicoplanin by a porous adsorption resin under selective elution conditions and recovering highly pure teicoplanin using activated carbon and/or ultrafiltration. In this regard, the method can further include ultrafiltration as pre-treatment before the culture broth is adsorbed into the porous adsorption resin so as to increase the purity of teicoplanin.

Abstract:
An aerogel type platinum-ruthenium-carbon catalyst of microporous structure maintaining long-term high catalytic activity, suitable for a direct methanol fuel cell, is manufactured by a sol-gel process, and supercritical drying while maintaining a microporous structure. The catalyst contains 5 to 70% by weight of platinum and ruthenium, remainder carbon, the platinum and ruthenium atomic ratio being of 1/4 to 4/1. Metal salts and base catalyst are added to a solution of organic gel materials, a solution of basic amine is added to the first solution, and the pH of the resulting solution is adjusted forming a sol, the sol is aged at 40 to 90 for 1 to 20 days forming and stabilizing the gel, solvent is removed from the gel by supercritical drying, and finally the aerogel is carbonized in an inert atmosphere, followed by hydrogen reduction.
