木版画 鋳造 第3問 以下の文は、 S. Strandh の “Machines, an illustrated history" からの抜粋で ある。 次の文を読んで、設問に解答せよ。 (ア) The tools of precision mechanics were, without doubt, the technical pre conditions for making wood cuts and for the development of printing. The oldest dated wood engraving is from 1418. It shows fine lines throughout 細部 and a richness of detal, which imply that the tools used, the knives, burins, and so on, must have been eminently suitable At this time, it was only the precision mechanics of clock making which could achieve the technique required for such tools. 精密機械技術 (イ) A (woodcut was produced by transferring a drawing, reversed from left to right, onto a carefully surface-ground "block" of wood, after which the surface wood on either side of each line in the drawing was cut away with a burin of forged steel. The remaining wood on all 'surfaces which were to be white in the drawing were then cut away with gravers and gouges, so that the lines of the drawing became raised. They were then inked and pressed against paper. これは 理由では ないから、 (~のときに、何 が原因か は不明) The woodcut method spread rapidly in the late Middle Ages when pictures were rarity. At first, skilful craftsmen made the woodcuts, but before long, eminent artists were themselves cutting their own drawings in wood. One of the first was the German Albrecht Duerer (1479-1528) who, in 1498, published the famous pictorial series of the Revelation of St. John. Graphics had become an independent art form-based on the progress of precision 酒の mechanics! 可動式の The 1440s saw the first book printed with movable die-cast type. (The letter press printing method used by Johann Gutenberg (1399?-1468) was basically the same as the one used for printing woodcuts, but Gutenberg used cast, movable type instead of cut blocks. The production of dies for the type was made possible by the tools of precision mechanics, too. It does not detract from Gutenberg's contribution that printing with movable type has been practised in the Far East, or more specifically Korea, two thousand years prior to this. Several of the techniques described here, which developed so quickly during the technical revolution of the Renaissance, had had predecessors in other parts of the world.

青チャートIA、場合の数と確率について質問があります。下に写真を貼り付けたのですが、なぜ同じような問題でもこのように解き方が変わってしまうのでしょうか。なるべくわかりやすく教えてください🙇🏻‍♀️よろしくお願いします。

378 基本例 例題 30 最短経路の数 右の図のように,道路が碁盤の目のようになった街がある。 地点Aから地点Bまでの長さが最短の道を行くとき,次 の場合は何通りの道順があるか。 (1) 全部の道順 (2) 地点 Cを通る。 [類 東北大〕 ○ (3)地点Pは通らない。 (4) 地点Pも地点 Q も通らない。 + 基本27 AL 指針AからBへの最短経路は,右の図で 右進 または 上進する ことによって得られる。 右へ1区画進むことを,上へ1区 画進むことを↑ で表すとき,例えば, 右の図のような2つの まちがしが敗因 (3) 通行止め からのリスタート最短経路は 地点配置 赤の経路なら 青の経路なら -1--111-1-1 0000 111→11→1→→ で表される。 したがって, AからBへの最短経路は, 5個 16個の同じものを含む順列で与えられる。 (2) A → C, C→B と分けて考える。 積の法則を利用。 (3) (Pを通らない)=(全道順) (P を通る) で計算。 C A (4) すべての道順の集合をUPを通る道順の集合をP, Q を通る道順の集合をQと n(PnQ)=n(PUQ)=n(U)-n (PUQ) ド・モルガンの すると, 求めるのは つまり ここで つまり (PもQも通らない)=(全道順)-(PまたはQを通る) 個数定理 n(PUQ)=n(P)+n(Q)-n(PnQ) 法則 (P または Q を通る) = (P を通る) + (Q を通る) (PとQを通る) 右へ1区画進むことを→, 上へ1区画進むことを↑で表す。 解答 (1) 最短の道順は5個, 16個の順列で表されるから 11! 5!6! 11-10-9-8-7 5・4・3・2・1 462(通り) (2) A から Cまでの道順 CからBまでの道順はそれぞれ 組合せで考えてもよい。 次ページの別解参照。 AからCまでで 3! 8! -=3(通り), -=70(通り) 1!2! 4!4! →1個, 2個 CからBまでで よって, 求める道順は 3×70=210(通り) →4個 14個 5! 5!
