In a digital TV broadcast signal receiver connected to a multi-directional antenna called smart antenna, having a first number, for example, sixteen of signal receiving directions defined in a technical standard such as EIA-909, a simplified multi-directional antenna having a second number, for example, four or eight signal receiving directions smaller than the first number is connectable. An estimated write size of a write operation of the user into the file system is managed as an accumulated value. The category is identified on the card and items are arranged in subgroups according to different degrees of difficulty regarding their perceived recognizability as being members of a set falling within the category. The physical model is based on the obtained physical status quantities. A signal having a first signal portion at a first bandwidth containing an indication of an operating bandwidth selected from a plurality of bandwidths used for a further signal portion is provided. The barrier laminate has an organic layer obtained by curing a polymerizable composition comprising a compound represented by the following formula ;wherein R1’s represent a substituent, and R1’s each may be the same or different to each other; n’s are an integer of 0 to 5, and n’s each may be the same or different to each other; provided that at least one of R1’s comprises a polymerizable group.
