Abstract
The purpose of this study is to determine whether or not a relationship exists between the time of an industrial injury and a specific position on the biorhythm scale known as a critical day.
Ninety-six employees who worked at the E. I. du Pont de Nemours Plant in Parlin, New Jersey served as a test group during 1980. In order to determine if a relationship did exist, the subjects' biorhythmic cycles for 1980 were charted and then their injury performance was monitored during that year to see if the injury date corresponded with a critical day. An additional test was set up at the E. I. du Pont de Nemours Plant in Florence, South Carolina. In this test, the 110 casting area employees' biorhythms were plotted for the first six (6) months of 1986. The group was divided into four groups. Each month one of the four groups received warnings based on their critical days, one received random warnings and, to act as a control group, two received no warnings. The four groups were rotated during each of the six months of the test. In addition, the Florence employees' performance for 1985 was analyzed as was the Parlin employees.
For the 1980 and 1985 groups, the statistical method Chi-square was used to determine whether or not a significant relationship existed between the two factors. Also, a comparison was made among the three 1986 test groups to determine what impact warnings had on employee safety performance.
These analyses showed that no significant relationship existed between the date of the occurrence of an injury and a specific position on the biorhythm scale known as a critical day.
Also, no significant difference was observed for any of the 1986 test groups.
