Described herein are microneedle bioactive agent delivery systems, associated apparatus and methods of using such. The non-volatile memory cell includes a first conductivity type semiconductor substrate, second conductivity type sourcedrain regions longitudinally arranged in a direction to be parallel to each other and separated from each other by a predetermined distance in the semiconductor substrate, such that the second conductive sourcedrain regions define a channel region therebetween. In addition, there is provided a cable core wire management system, a cable core wire management method and a cable core wire management program which realize an improvement in efficiency and reliability of construction work performed on networks such as optical fiber networks. By use of this structure, lateral expansion widths of the P type buried diffusion layers are reduced.
