A catalyst for catalytic partial oxidation of hydrocarbon, having high thermal shock resistance, and a process for producing a synthesis gas using the catalyst are provided. And once it is finished, using the initial values of the coefficients set at the step S3 as starting, the optimization is progressed with renewing each value of the coefficients on the following iterating calculations. The method can include forming a location-based group of wireless terminals disposed within a proximity of a location and transmitting a media message to each of the wireless terminals in the location-based group.
