Abstract: Provided is a sensory substitution apparatus and method that combines two or more pieces of multi-sense sensory information to be converted into different multi-sense sensory information, in which received pieces of multiple information are combined to suit sensory characteristics of the user's body and efficiently transmitted to a different sensory organ. According to the present invention includes: receiving input sensory information; classifying the input sensory information; calculating an importance of each of individual sensory information; determining a target sense for which part or all of the individual sensory information, of which an importance is calculated, is to be converted into a new sensory signal incongruent with the corresponding individual sense; and converting the input sensory information into target sensory information to be transmitted to the determined target sense which is an organ.

Abstract: An amine aqueous solution for forming an active layer of a polyamide reverse osmosis composite membrane is prepared, which consists of 0.1 through 20 weight % of polyfunctional aromatic amine monomer, 0.1 through 20 weight % of multi-functional tertiary alcohol amine, 0.1 through 20 weight % of strong acid, and 40 through 99.7 weight % of water.
