Abstract: A method of controlling a mobile terminal, and which includes controlling, via a Windows processor, a plurality of peripheral devices of the mobile terminal; switching, via the Windows processor, the mobile terminal into a sleep state; granting, via an arbiter control processor, a control authority for controlling predetermined peripheral devices among the plurality of peripheral device to a 3G modem when the mobile terminal is switched into the sleep state; receiving, via a communication unit on the mobile terminal, an incoming call; and managing, via the 3G modem, circuit data and the predetermined peripheral devices for the incoming call.

Abstract: The present invention relates to a method for efficiently proliferating and differentiating natural killer cells (NK cells) from umbilical cord blood, more precisely a method for efficiently proliferating and differentiating natural killer cells from umbilical cord blood comprising the following steps: 1) preparing CD3 negative cells by eliminating CD3 positive T-cells from umbilical cord blood derived mononuclear cells; and 2) culturing the CD3 negative cells after treating various cytokines thereto. The present invention is advantageous in obtaining high purity NK cells in a short period of time by inducing NK cells from CD3 negative cells, compared with the conventional method inducing NK cells from haematopoietic stem cells, and in promoting NK cell proliferation and differentiation by treating different cytokines together, for example by the co-treatment of IL-15 and IL-21.

Abstract: A diamond field emitter and a fabrication method thereof, in which a pretreatment is performed on a surface of an Si substrate in order that diamond nuclei are uniformly formed on the Si substrate during a diamond deposition, an oxide film such as an SiO2 film is deposited on the pretreated surface of the Si substrate and removed after an etching process so that diamond powder can be selectively remained during the etching process, thus the effect of the surface pretreatment of the Si substrate remains in the selected portion during the etching process, and it is also possible to uniformly deposit the diamond in said portion. According to the present invention, the diamond field emitter having excellent and uniform field emission characteristic can be manufactured because the field emission is easily achieved at a tip shaped field emission section, and, moreover, the diamond placed on an upper end portion of the tip increases electron emission effect.
