Insulation for a rocket motor is provided, as is a method for insulating a rocket motor. An equation describing a model in the multi-dimensional space is provided. An update program for changing the processing of the receiving terminal may be transmitted to the specific receiving terminal along with the unique terminal information. Then, information on the preferential treatment is transmitted from the server to the controller, and is displayed on a display unit of the controller. The telepresence robot may rotate an upper portion independent from a lower portion. An embodiment of the present invention improves the techniques associated with refreshing multidimensional database information when the multidimensional data has been changed.
