Abstract: Disclosed is a method of managing a search term inputted to a search server. The method includes maintaining a search pocket database for storing a first search term associated with a user, the first search term received from the user when the user is authenticated, receiving at least one second search term from the user when the user is not authenticated, and storing the second search term in a user terminal associated with the user, in a temporary file. The method further includes providing the second search term to the user by referring to the temporary file when the state of the user is changed from the unauthenticated state to the authenticated state, selecting at least one certain search term from the at least one second search term, according to the user's selection, and storing and managing the selected at least one certain search term in the search pocket database together with the first search term.

Abstract: An apparatus for coating polyimide layer includes a print table, an inkjet head, and a polyimide liquid supply tank, wherein the inkjet head is configured to jet the polyimide liquid in a scan-coating and be shifted by a predetermined shift pitch in a direction until 2N times of scan-coating occurs in which N?2 and N is a natural number. A method for coating polyimide layer includes placing a substrate, loading a polyimide liquid vessel into a polyimide liquid supply tank, jetting the polyimide liquid onto the substrate in a scan-coating, repeating the jetting the polyimide liquid onto the substrate in a scan-coating and the shifting the inkjet head by a predetermined shift pitch until 2N times of scan-coating occurs in which N?2 and N is a natural number.
