Abstract: A method for migrating data from a relational DB to a graph DB comprises, collecting constraints of referencing tables having a column set as a foreign key, among tables of a relational DB which is a migration source DB, determining a relation type of each of the referencing tables, based on constraints of the referencing table, determining a node generation target table and a relation frame for each of the referencing tables, based on the relation type of the referencing table, and converting data in each row of the node generation target table into a node of a graph DB which is a migration target DB and generating a relation of the graph DB, which connects the generated nodes, according to the relation frame.

Abstract: A dye-sensitized solar cell, an electrode of the dye-sensitized solar cell, a method of manufacturing the electrode of the dye-sensitized solar cell are disclosed. The method of manufacturing the electrode of the dye-sensitized solar cell in accordance with an embodiment of the present invention includes: forming a metal transparent electrode on one surface of a transparent polymer board, in which the metal transparent electrode has holes formed therein; forming a electron transfer layer on the metal transparent electrode; and absorbing photosensitive dye into the electron transfer layer. According to the method as set forth above, a flexible solar cell can be implemented by using a flexible electrode, and another transparent electrode layer using ITO can be omitted by using the nano-patterned metal transparent electrode. Therefore, the highly efficient dye-sensitized solar cell can be implemented by the excellent conductivity of metals and the plasmon effect.

Abstract: A flexible dye-sensitized solar cell, an electrode of a flexible dye-sensitized solar cell and a method of manufacturing the flexible dye-sensitized solar cell are disclosed. The method of manufacturing the flexible dye-sensitized solar cell in accordance with an embodiment of the present invention includes: forming a separation layer on a carrier; forming a dye-absorption layer on the separation layer; forming a carbon-nanotube layer on the dye-absorption layer; forming a cathode polymer layer on the carbon-nanotube layer, in which the cathode polymer layer is flexible; and separating the carrier by removing the separation layer. Although the high temperature annealing process associated with the dye-sensitized solar cell is required, a flexible cathode transparent electrode can be manufactured by using the carbon nanotube, because the cathode can be manufactured by using the carbon nanotube and a flexible transparent board is used.

Abstract: Provided is a showerhead that can inject a reaction gas into a reaction chamber in a manner such that the injected reaction gas form a spiral vortex flow field. Therefore, the injected reaction gas can be mixed within a shorter distance, and thus the effective deposition radius of a wafer can be increased so that uniform-density deposition can be performed on the entire surface of the wafer using the mixed reaction gas.
