"Areal difference in the relation of walking activity to the surface conditions observable in the members of deck section on board a 2,000 G.T. fishery training vessel."

"The pedometer readings for the 6 members of the deck section on board a 2,000 G.T. fishery training vessel were recorded twice a day over 53 effective days during the New Zealand-Hawaii cruise in 1994-95. The influential factors in the walking activity of these members in the respective areas were sought by estimating the multiple linear regression equations on the presettable variables (number of days after departure and the AM-PM dummy variable) and the variables relating to the surface conditions. The results obtained were summarized as follows: (1) Significant equations could be obtained for 16 cases (member*area) out of 30. Their distribution had no relation to the member and the area. (2) The actually adopted explanation variables in the equations differed according to the area even among the equations for the activity of the same members. (3) The decreasing trend with the increase in the variables showing the roughness of the surface conditions could be admitted for at most 1/3 of the cases, even when the variables showing significant correlation to the roughness variables were regarded to be adopted instead of them."
