Abstract

1994-95年に2,000総トンの漁業練習船が行ったニュージランド・ハワイ航海において,各職種乗組員18名の歩行活動を計測し,それに及ぼす航海日数,海面状態に関する諸要因の影響を重回帰分析によって調べ,次の結果が得られた: (1)説明変数として重回帰式に取り入れられた変数名と,それらの偏回帰係数の符号だけに着目しても,得られた重回帰式の型は個人によって異なる。 (2)歩行活動の概要は航海日数,海域を表すダミー変数,午前午後の差を表すダミー変数によって決まり,海面状態(風向,風速,風浪,うねりの方向,高さおよび周期)は2次的な重要性しか持たない。 (3)重回帰式の多様性を含む得られた結果は,職務内容と関係が深いことがインタビューによって裏付けられた。

The pedometer readings of the 18 crew members having different jobs on board a 2,000 G.T. fishery trainingvessel were recorded twice a day over 53 effective days during the New Zealand-Hawaii Cruise in 1994-95.Using these records, the influential factors in the walking activity of the respective members were sought byestimating the multiple linear regression equations for the number of days sailed, the AM-PM dummy variable(category 1), the area dummy ones (category 2) and the variables relating to the surface conditions (category 3).The following results were obtained : (1) The fom of the equation expressing the activity of the respectivemembers differed according to the members with respect to the actually adopted variables and the sign of theirpartial regression coefficient, (2) the walking activity primarily depended on the variables in categories 1 and 2,and secondarily on those of category 3, and (3) interviews with the members concemed indicated that the obtainedresults including the diversity in the estimated equation had a close relation to the details of the duty work.
