Abstract: Disclosed is a small cell base station managing method of a small cell base station managing system which manages a plurality of small cell base stations. The small cell base station managing method includes receiving a reconfiguration request; selecting a radio access technology (hereinafter, referred to as RAT) of a selected small cell base station according the reconfiguration request; and requesting the selected small cell base station to operate using the selected RAT.

Abstract: Provided is a color patterning method, in which electrophoretic microcapsules are used. The patterning method may include preparing a microcapsule slurry, in which electrophoretic microcapsules and a water-soluble binder are mixed, coating the microcapsule slurry on a first substrate, moving the microcapsules from the first substrate to a stamp, and moving the microcapsules from the stamp to a second substrate to form patterns. By using the patterning method, it is possible to form an intended pattern without physical and chemical damage on the microcapsules and realize an improved color electronic paper.

Abstract: When a user enters an indoor space, such as a building, where it is difficult to obtain absolute positioning information, probable indoor path information is estimated based on outer appearance information of the building that the user is presumed to have entered and the moving distance and moving direction of the user. Also, location information calculated according to an estimated navigation method is selectively corrected by using the estimated indoor path information.

Abstract: Provided is a method of forming an organic thin film including forming a first layer containing a first organic material on a substrate, performing a first imprint process on the first layer using a pattern mold, forming a second layer containing a second organic material on the first layer after the first imprint process, and performing a second imprint process on the second layer using a blanket mold.

Abstract: In a piezoelectric speaker, an acoustic diaphragm is thicker than a piezoelectric thin film and is formed of a more flexible and higher elasticity material than the piezoelectric thin film, thereby greatly improving output sound pressure in a low frequency band and reducing sound distortion. Further, the piezoelectric thin film is attached to the acoustic diaphragm in an inclined structure in which the piezoelectric thin film is horizontally turned from the acoustic diaphragm, thereby preventing a standing wave from being created by structural symmetry and minimizing sound distortion.

Abstract: A semiconductor package is provided. The semiconductor package includes a package body, a plurality of semiconductor chips, and an external connection terminal. The package body is stacked with a plurality of sheets where conductive patterns and vias are disposed. The plurality of semiconductor chips are inserted into insert slots extending from one surface of the package body. The external connection terminal is provided on other surface opposite to the one surface of the package body. Here, the plurality of semiconductor chips are electrically connected to the external connection terminal.
