Abstract: The use of an immune killer cell against circulating tumor cells in solid tumor treatment, which comprises transfusing the immune killer cell into peripheral blood of a subject to act on the circulating tumor cells in peripheral blood. In the use of a solid tumor treatment, the immune killer cell can act on the circulating tumor cells by means of transfusing an effective dose of the immune killer cell into the peripheral blood of the subject, which is beneficial for blocking solid tumor metastasis by means of inhibiting the colonization of circulating tumor cells in tissue and improving the survival period of the subject.

Abstract: Provided is a golf play assisting system enabling players to get an intuitive picture of the condition of the grain. When an image of a portion of a turf target is taken by a player to study the grain of the target turf by using an image-taking device of a mobile terminal, an image processing and analyzing unit performs image processing and image analysis against original image data captured thereby. As a result, symbolized images of the grain data, indicating a direction and inclination of the grain at each specific location in the turf target, are then displayed on a display unit of the mobile terminal on top of a processed image data visibly highlighting the grain of the target turf.

Abstract: Provided is a display control device allowing the direction of a map information shown on a display to be correctly recognized. A display control unit displays on a display of a mobile terminal map information reproducing a scenery, thus making it possible to display on top of the map information a coordinate position display section corresponding to the current location of the mobile terminal. Here, there are provided a map information display determination section for displaying on the display the map information in a fixed orientation; and an angular difference display determination section for displaying on the display an angular difference between an angle of direction in which the mobile terminal is pointed and an angle of direction of the map information shown on the display.
