Abstract

1, 000GT型練習船が1997年11月~12月に三陸沖及び四国沖で行った中層トロール中に集めた作業時問の長さと歩行活動に関する記録から求めた重回帰式に,乗組員の活動の変化を通じてそれらに影響を及ぼすと考えられる要因が説明変数として取り入れられるかどうかを検討し,次の結果が得られた: 1.投網時間の長さは主に網口の開きを確認するための時間の長さ,揚網時間の長さは主にワープの長さによって決まる。しかし,これらの時間の長さには乗組員の活動を通じた影響がみられた。 2.各乗組員の歩行活動を表示する重回帰式の説明変数には,船や網を通じてでなく乗組員を通じて影響を及ぼすと考えられる変数が含まれる。 3.各乗組員の歩行活動を表示する重回帰式の説明変数には作業分担と関係が見られる。

The present report deals with the relation between working conditions and the length of time for shootingand hauling a midwater trawl or the walking activity of the respective crew members during this work, using therecords collected from a l,000 G. T. fishery training vessel in Nov. and Dec. of 1997 in the waters off the eastcoast of Japan. Whether or not the time length and the walking activity were affected by the variables which mayaffect them through the physical or psychological conditions of the crew members, was examined by estimatingmultipule linear regression equations. The obtained equations indicated that 1) The time length for shooting thetrawl depended on the probable length of the time for confirmation of the net mouth being safely opened andthat for hauling depended on the length of the warps. These time lengths could not be free from the influence ofthe working conditions, through the activity of the crew members invoIved. 2) The equations for the walkingactivity of the respective members during this work included some variables the probable influence of which wasthrough the conditions of the crew members. 3) The estimated equations suggested that the actually adoptedexplanation variables had a relation to the allotted charge on board.
