A method is disclosed of providing geo-relevant information based on a location. The treatment method comprises impregnating pores of the electrocatalyst particles with an impregnant wherein the pores comprise micropores which have an aperture size less than 0. The arm body is provided with a plurality of substrate suction pads capable of sticking to the upper surface of the glass substrate by suction to hold the glass substrate, and a plurality of electronic part suction pads disposed above the electronic parts so as to correspond to the electronic parts, respectively. A number of 2D IBDRs can be merged into a subset of similar 2D IBDRs by characterizing desired rule geometries, sorting the 2D IBDRs into groups according to the desired rule geometries, merging the groups of 2D IBDRs into a single representative search pattern.
