Abstract:
An intimacy management terminal and a method thereof are provided to extract inclination data based on acquaintance information, calculate intimacy degree through the acquaintance information and an acquaintance schedule and confirm the intimacy degree at any time. The acquaintance information of user is stored in a memory unit. Inclination data about acquaintance is calculated based on the acquaintance information of the acquaintance stored in the memory unit. The personal schedule with acquaintance is inputted to the terminal. The closeness with acquaintance is calculated based on inclination data and the inputted personal information in the memory unit. The calculated closeness is outputted through the output unit. In case the reduced closeness is below the standards closeness and the calculated closeness is gradually reduced as time passes, a warning message is outputted.
Abstract:
A method of producing low resistivity SWNT bucky paper through Cu reducing reaction is provided to improve electric resistance of the bucky paper, which is useful in manufacturing microfine artificial muscles and super resistance composite materials by conducting electrolysis in a copper salt solution to combine the paper with copper molecules. The method comprises coupling of copper molecules to SWNT bucky paper(2) through copper reduction to lower electric resistivity. The copper reduction step is electrolysis of a copper salt solution and the electrolysis includes the steps of: preparing the copper salt; immersing a conductor connected to (+) pole and SWNT bucky paper connected to (-) pole in the copper salt; and applying voltage to both of (+) and (-) poles. The copper salt is copper acetate(1). SWNT is carbon nano-tube manufactured by a high pressure carbon monoxide manner. The low resistivity SWNT bucky paper has copper molecules combined thereto.
