    摘要： The present invention discloses a cable-driven manipulator comprising an operating unit having a drive motor, and a pulley rotated by the drive motor. An upper arm is coupled, through a joint, to one side of the operating unit. A forearm coupled, through a joint, to the other side of the upper arm by the cable. A gripper of an end effector operably coupled to the forearm, a cable compensation device is installed between the upper arm and the forearm so as to maintain constant the length of the cable that transmits the power of the operating unit to the end effector during the pivoting of the forearm. It is thus possible to prevent the variation of tensile force due to the variation of the length of the cable for operating the end effector during the pivoting of the forearm or the unintended malfunction of the end effector.

    摘要： There is provided a solar cell including: a substrate; an energy absorption layer formed on the substrate and having a plurality of nanowire structures, each of the nanowire structures including an n-type semiconductor and a p-type semiconductor joined together; and n-type and p-type electrodes electrically connected to the n-type and p-type semiconductors, respectively. The solar cell exhibits high photoelectric efficiency due to pn junction of the nanowire structures. Further, the solar cell can absorb light falling within a substantially whole range of solar spectrum and does not require an epitaxial growth process, thereby overcoming drawbacks of an epitaxial layer such as crystal defect.

    摘要： A method and apparatus for browsing a plurality of broadcast programs are provided. The method includes classifying a plurality of broadcast programs into one or more broadcast program groups with reference to electronic program guide (EPG) information or viewing records of a user regarding the broadcast programs, one-dimensionally arranging the broadcast programs so that the broadcast program groups are one-dimensionally arranged, displaying the broadcast programs and the broadcast program groups on a screen as a graphic image, and allowing the user to change a rule used for forming the broadcast program groups. Accordingly, it is possible to enable a user to effectively browse broadcast programs and to provide the user with a user interface customized for the user by using a simple one-dimensional input method and intuitively utilizing EPG information.
