Abstract |
During the six years from 2006 to 2011, based on a study of projects with an area equivalent to or less than $2,700m^2$ located in Jeju self-governing province, it was shown, through comparison with the pre-existing calculation methods, that there were many problems with the application of the standard cost. Accounting for the uniqueness of Jeju province, the study suggested an alternative method for applying the standard cost, basing it on property usage of either urban area or non-urban area pursuant to the National Land Planning and Utilization Act rather than land type of either mountain area or non-mountain area, with the utilization of T-test and ANOVA raising the reliability of this study. |
