This chapter briefly explains the distributed project management of four joint departments for first-grade joint project-based learning (PBL). That is, conventional studies and purpose, capital, competence and ability of four kinds of distributed project management were presented, and relations among them are shown after describing background (included prehistory of PBL in Osaka Institute of Technology (O.I.T.)). Then, consideration and analysis about communication, interaction, cooperation, merit, week-point, effect and inference were discussed. Some case studies were described about open innovation and competences in stakeholder management. They were distinctive and superior in first-grade PBL of O.I.T. Finally, some future themes were presented.

The suitability of Al-Mg alloys for recycling was investigated using energy-saving processes. The Al-Mg alloy is a non-heat-treatable alloy and has the advantage of energy saving in comparison with heat-treatable alloys. Al-Mg alloys with Mg contents ranging from 4.5–10% were tested. Die casting, cast-forging, and roll casting were selected as energy-saving processes, as they have the advantage of process saving. A single-roll caster equipped with a scraper was used as the roll-caster. Fe was added to the Al-Mg alloys at contents of 0.2%, 0.4%, 0.6%, and 0.8% to model recycled alloys used in automobile manufacture. In the selected processes, the tensile stress and 0.2% proof stress of the Al-Mg alloys were little influenced by the added Fe content, whereas the elongation tended to decrease as the Fe content increased. The process influenced the degree to which the Fe content affected the elongation, and it was found that a suitable Mg content for recycling depends on the target process.
