A content management system and method work as a companion to other applications that control the system. Information is also provided, representative of clusters of defects on the wafer. The resilient member is permanently maintained an invariable compressed state between the base wall and the resisting face of the ferrule to provide an invariable forward resilient force to the ferrule for fixing the ferrule to the lens member, when the optical-electrical connector is used and unused. Once positioned near the stomach body, the gastric reduction assembly allows for the external compression of the stomach body to limit food intake. Therefore, unlike the case where the non-display period is provided by changing the electric potential of a cathode wiring, the present invention is hardly affected by dulled signal waveform.
