The Study of Public Speaking Focusing on Listening [Comparison of the Textbook in USA]

パブリック・スピーキングは，スピーチの完成形として，現行中学校教科書５社のすべてが第３学年で取り上げている単元である。しかしながら，日本の教科書におけるパブリック・スピーキングは「聞くこと」の視点からの記述が存在せず，不完全であり，「話すこと」の視点の記述に片寄っていると言わざるを得ない。パブリック・スピーキングは，一人の話し手が多数の聴衆に向けてスピーチをする「独話」であることから，一見，「話すこと」の学習のようだが，アメリカ合衆国の教科書では「話すこと」と「聞くこと」の双方向の活動として捉えられ，特に「聞くこと」を重視している。本稿では，アメリカと日本の国語教科書におけるパブリック・スピーキングについての認識の違いを検証する。そして，アメリカの教科書から日本の中学生の学習にふさわしい情報を抽出し，「聞くこと」に着目した新しいパブリック・スピーキングの在り方を考察する

鶴洋丸のプロペラ塗装効果の実験－II

The case of, departure of ship from Port ; the ship must arrived at the destination in security. Because, it is mission of ship. The propulsion system of ship is very important part for security of ship and crew, Therefore, engineers are has important watch to judge about clean or dirty of propeller blade. This judge does carry out departure of ship from port. Propeller blade was certain soiled by adhere to the seaweeds and marine fouling animals of anchored ship in harbor, however, that degree of dirty does not judgment from on board. This time, a way condition of propeller underwater is observed to do diving of professional diver, but, this way is both very danger and need high cost. A series of experiments, researched degree of dirty of propeller blade at measurement fuel pump index correspond with idle running of main engine and twice propulsion performance test from Mar. 1999 to Aug. 2000 on board the Kakuyo Maru. From these experements some result are obtained : i）The fuel pump index is increased from 10.0mm to 10.8mm ； when, dirty condition of prolPeller blade. it rate of climb was 8％. Some formulae figure calculated in unit of percentage, rate of propeller revolution, Rp and shaft horse Power, Ne are : Experiment－3（Exp－3） Ne=15.8331Rp－78.80 （r=0.9954） Experiment－4（Exp－4） Ne=17.9308Rp－163.02 （r=0.9993

Experimental Effect of Propeller-Coating of Training Ship Kakuyo Maru I

While ships are constructed and after leaving dock, the bottom and the propeller of ships are smooth and clean, however, marine fouling animals adhere to the bottom and the propeller of anchored ships for a long time in harbour. As a result, frictional resistance of ships hull and a shaft horse power of ships increase. Therefore, the ships hull and the propeller of ships are cleaned and painted again in the dock. The hull of Training Ship Kakuyo Maru had been painted self-polishing anti-fouling paint (SP type A/F) from 1978 to 1991, however, the SP type A/F were not used at present because of the ocean pollution. In this study, prevention effects of marine fouling animals adhere to the bottom and the propeller which coated paint was made of a silicone resin, were examined. As a result, it is seemed that the propeller coated with silicone resin prevented adhere to marine fouling animals, promoted decrease of frictional resistance, it turned out the ship speed didn\u27t decrease and fuel consumption value didn\u27t increase during this voyage

船体および推進器の汚損が推進性能に与える影響

While the oil resoures have become 60% among the overall cost, the propulsive energy which is used to rotate the propeller have been consumed as the about 32% against total shaft horse power which is made in the marine main engine. We consider that the using fuel oil must be the saving of the energy converting from the thermal calorific fuel oil energy to the rotating energy of propeIler. So, here we quantitatively clarifired for saving energy of main engine of T/V Kakuyo?Maru during 1990 to 1998. Due to advancing of the marine fouling animals of the hull bottom and the propeller blades, the propulsive coefficient have been deteriorated． In this study, it is recognized that fuel consumption value increases up until 22.24% and SM increases large up until 9.4～16.4% for the second half-year of each year
