Inner factors, such as seasickness or fatigue, have a seriously influence on the function of human body. As a result, on the response characteristics of human body to ship oscillatory motions changes. To clarify the relationship between the inner factors and the response characteristics, we gathered information about inner factors during the voyage by the questionnaires. Also we measured ship motions and sea conditions. We tried some statistical analyses with the sampled data. The results are summarized as follows; (1) There is an existence of high correlation between seasickness and physiological, psychological, nerve sensational symptom of fatigue, respectively, and those relations are statistically significant for each navigation. (2) Ship accerelations in X, Y and Z-direction influence strongly on a degree of seasickness and every subjective symptom of fatigue, and the period of encounter waves indicate negative correlation with them. (3) We could estimate seasickness with nonlinear multi-regression analysis. As explanatory variables, we selected the first moment of spectrum (M_1) of ship accelerations in X, Y and Z-directions, and time hours underway.
