Mathematical relationships between basic growth function and bondi k-Factor

This study was designed to investigate mathematical relationships between basic growth function and Bondi K-factor from the viewpoint of 4-dimensional phenomena. The results obtained were as follows. Basic growth function was mathematically related to Bondi K-factor. The product of relative growth rate and time (rt) where Wc' replaced W showed a closer mathematical relationship to natural logarithm of Bondi K-factor. If based on these mathematical relationships, then basic growth phenomena look like 4-dimensional phenomena. Applying basic growth function to 3-dimensional body frame size was also discussed. In addition, appendix was added to give corrected versions to problems that were found in previous reports.
