In response to a predetermined user’s instruction, predetermined post-processing is separated from a job adapted to cause a predetermined post-processor to perform the predetermined post-processing together with performance of print-processing. A cleaning assembly provided at a distal end of the elongate tubular member radially expands to engage the interior wall of the endotracheal tube, for cleaning thereof by an irregular configuration on an exterior surface, achieving an effective cleaning engagement. The grain boundary fracture toughness KICgb is determined by the equation KICgb=KIC\xb7cos2, wherein KIC is fracture toughness, and PIF is a percentage of the intergranular fracture. When the first conductive element and the second conductive element are connected to the voltage source, an electrochemical reaction occurs causing the neurotoxin to release from the electroactive layer and elute to a target location.
