An instruction target object which is located outside a predetermined area of a virtual space is detected at an interval of the unit time, and a substitute icon associated with the instruction target object is displayed in a screen. The presence andor titre of neutralizing antibodies in a test sample are determined in a competitive format, where known, type-specific, fluorescently labeled neutralizing monoclonal antibodies compete with antibodies within a test sample for binding to conformationally sensitive, neutralizing epitopes on specific HPV-VLPs. A priority value is determined for each of the at least two data sets. The electronic assembly may comprise one or more signal terminals coupled to the electronic component.
