Abstract
Many projects based on Application Packages have already been carried out, emphasizing the merits of using them, but it seems less attention paid to the problems that may occur when applying those packages. For example, add-on developments or revisions to the original program may be necessary in order to meet individual application requirements. Additionally, specific problems owing to the adoption of the Application Packages may of course occur. In this paper, I would like to study the way of maximizing the merits of Application Packages, through my experience of facing and solving such problems.
