A method of generating popularity rankings of search terms includes generating a ranking value table including ranking values corresponding to rankings of search terms, determining first ranking values corresponding to previous rankings of a plurality of search terms and second ranking values corresponding to current rankings of the plurality of search terms by using the ranking value table, and obtaining difference values based on differences between the first ranking values and the second ranking values of the plurality of search terms, respectively, and determining popularity rankings of the plurality of search terms by using the difference values.

Server, control method thereof, and system for producing rankings of search terms whose popularities increase rapidly

The present invention relates to a biomolecule-based electronic device in which the biomolecule with redox potential is directly immobilized on the substrate. The present invention enables to excellently exhibit the capability of a protein-based bio-memory device in which it is preferable to use the substrate on which cysteine-introduced recombinant proteins are effectively immobilized and a self-assembled layer (SAM) is fabricated. It becomes realized that a redox potential is regulated using intrinsic redox potential of the protein dependent on applied voltage. The present invention provides a novel operating method in which three potentials are applied throughout four steps. The present invention has some advantages of fabricating a protein layer in a convenient manner and inducing electron transfer by fundamental electrochemical or electronic operation. The method of this invention is considered as a new concept in the senses that intrinsic electron transfer mechanisms induced by natural-occurring biomolecules are used to develop an information storage device.
