        The production method of micro sacrificial plastic mold insert metal injection molding, namely process has been proposed to solve specific problems involving the miniaturization of MIM. Two types of sacrificial plastic molds (SP-mold) with fine structures were used: 1) PMMA resist, 2) PMMA mold injected into Ni-electroform, which is a typical LIGA () process. Stainless steel 316L feedstock was injection-molded into the SP-molds with multi-pillar structures. This study focused on the effects of metal particle size and processing conditions on the shrinkage, transcription and surface roughness of sintered parts.

        To transfer educational research into practice, to sustain innovative practices, and to enable schools to implement curricular reform, leadership at each level-national, local, school, and classroom-is essential. The term "e-leadership" is used to connote a new style of leadership suited to the new electronic environment. This paper illustrates how the findings of an international comparative study informed the development of an international eleadership training program for educational leaders from governments and schools within the AsiaPacific region. First, case reports were developed for 17 4 information and communication technology (JCT) innovation projects in 28 countries. Second, the case reports were analyzed to identify key factors about the innovative classrooms and their contexts. Six key dimensions were found. Third, a workshop was held for participants from ten APEC economies to prepare ICT implementation plans, taking into account the findings from the case study research. This paper reports the major findings of the international comparative study as well as the lessons learnt from this research-into-practice experience, including the vital role of e-leadership at all levels of the education system.
