A method of forming a unitary, composite structural member, and a member formed in accordance with the process. A user selects an electronic mail message to be published and moves the selected electronic message to a designated folder. As such, the present invention provides a simplified and easily scalable Bluetooth coverage infrastructure, allows pooling the resources of Bluetooth access points for best performancecost ratio and dynamic RF routingfiltering in capacity management, and simplifies the provisioning in the system. A paramagnetic metal ion is coordinated to the ligand. A second outlet hole is provided in the housing at a position situated at a distance from the first outlet hole and any inlet hole so that the air leaving the second outlet hole will have flown at least through a depth of the filtering material substantially corresponding to the depth of the filtering material for the air flowing from the inlet hole to the first outlet hole. A terminal apparatus, when participating in a hierarchical structure of a certain distribution channel, acquires information on the hierarchical structure, and displays participation statuses in the hierarchical structure of a plurality of terminal apparatus configuring the hierarchical structure in a predetermined topology information display area 22.
