A study on the decrement of work efficient by the oscillation

In the future it is expected that construction work on the very large floating structure similar to the MEGA-FLOAT will increase. In this study, the working characteristic and the effect on board of oscillating ships by measuring the finger pulse is investigated. Experiments were carried out to analyze the trend of decreasing work efficiency and the effect to workers motion using various methods. The first experiment investigated the effect of oscillation to physical motion. This experiment considered walking motion on the passage. The next experiment examined considered the effect on sensitive work. In this experiment, the amount of the water poured into the empty bottle from the kettle was observed. The third experiment evaluated the relation between oscillation and thinking capability resulting from a simple test of calculation. Results of this study have shown that the decrease in work efficiency was closely connected to the delayed reaction of the human body with the oscillation.
