The invention involves methods and materials for treating and preventing non-invasive fungus-induced mucositis. Randomized transmission times in one embodiment and two-phase unique transmission schedules in another lessen the possibility of on-going collisions between two or more transmitters contending for the base station at the same time. Alternatively, or additionally, the target RAT may detect that the handover was triggered too early and may inform the source RAT or command the UE to return to the source RAT. In the identity-blocking service, the service promoter may disclose the current physical location of a mobile subscriber to a third party subscribing to the identity-blocking service. The information processing apparatus converts the drawing data into drawing data of another format or converts the drawing data into image data if the combination of the print setting data and the drawing data is determined not to be the standard combination. The document management system is arranged such that a host computer, an image information processing apparatus, and a document management server which manages electronic document data are connected to each other on a network.
