工業製品を開発する上で、実物による実験を簡略化、省力化するための道具の一つとして広く導入されているCAE(Computer Aided Engineering)であるが、学童としての成長期にビデオやカードゲーム等で実物・実物理現象に触れる事が少なかった学生や若手技術者の中には、明らかに物理現象から乖離し間違ったCAE結果を見抜けない例が多く見られる。そこで本研究ではこの実現象とCAE結果の乖離を見抜く力を高めるPBLの例として割り箸ブリッジや竹とんぼに着目した。これらを題材として、形の構想からCAD(Computer Aided Design)による形状決定、CAEによる解析、その形状での製作と実験までゆるやかに関連づける技術教育を行った。その結果、これら技術的要素を含む例題に取り組むことで,強度や剛性が同機能で軽量な設計技術が得られるなどの成長が学生に促された。更に割り箸ブリッジのイベント性は学生の学習モチベーションを上げる事に大いに寄与する事や、竹とんぼ発射台は従来のCAD上だけの講義や、被計測体である実験模型が静止した回流式風洞実験に興味を持たなかった学生達の興味を引くなどの効果があった.この様に割り箸ブリッジと竹とんぼが設計教育を行う上で有用なテーマとなる可能性があることがわかった。

This paper introduce? origin legend o and history of process of coffee and consider about detail from scientific view. Coffee born at Ethiopia about 9 century. In those days, it had grown by Arabian doctors and had been used as medicine. There are some theories about birth of coffee and they are not obvious. The most famous legends describes about coffee make people refreshed and heal illness.

The relative increase of elderly people presents sever problems for modern society. As one example, elderly people confront various health-related problems. Development of better rehabilitation machines and equipment is important to resolve this problem and to preserve the health of elderly people in daily life. This study specifically addresses rowing machines. Rowing machines are aerobic exercise machines, as are running machines and bicycling machines. Aerobics exercise can alleviate hypertension, obesity, to sole pressure. Results showed differences among individuals at each examination, demonstrating that a load mechanism requires a load control system.

In order to put on a car, putting a person requiring care on a wheelchair, the welfare cars equipped with an expensive exclusive lift and slope were required until now. Then, the lifter new type which can make the person requiring care who does not purchase such welfare cars but has also put on the wheelchair get on and off easily from the backdoor of a common minivan was developed. In putting this lifter in practical use, the withstand-load examination at the time of the maximum authorized payload based on JIS regulation "home wheelchair lift", the impact test-proof, and the braking examination were carried out. It checked that the developed wheelchair lifter for in-vehicle loading was more satisfactory than the result of an experiment practically.

Japan is said to have an aging society. Assistive devices are therefore necessary to support the independence of elderly people. This study evaluated an Arm-Balancer arm support system developed for use by elderly or handicapped people without free arm motion. Measurements of rotational arm movement using a gyro sensor and an acceleration sensor revealed the possibility of evaluating arm movement using the Arm-Balancer.

The Akita National College of Technology, which opened in 1964, has sinceimplementedtraining tools forthe machine tools. In this study, we used a laser measuring machine tool to measure them. The turning and milling plant remain in use to the present day. Results show that their displacement has been strongly affrcted by aging, but their straightness has not been affected much.
