A device having a first configuration includes an input unit configured to accept an input made by a user, and a transmitting unit configured to add a safety confirmation number accepted by the input unit to a first call control signal and to transmit the first call control signal with the safety confirmation number. The packing element comprises a generally spherically shaped member which can be a perfect sphere, an ellipse, or some variation on either of the foregoing. Through a plurality of quick-connect couplings and a quick-connect electrical coupling the amenities module accesses a water source, a sewage outlet, and an electrical source from the housing unit in order to provide functional amenities to a tenant. The data from the ADCs may also be synchronized with external events. Said Darlington circuit comprises a current path which can be controlled on the output side in accordance with a control signal and said current path which can be controlled on the output side is coupled between the rectifier output connections. Calix4arene-nucleoside and calix4arene-oligonucleotide hybrids of the present invention can effectively recognize DNA or RNA through triplex formation by bonding between calix4arene containing cavity and biologically active substance.
