Abstract

Human bones provide plentiful information about height, sex, age, race and enable individual identification. Most of all, sex estimation is a basic and essential task and non-metric sex estimation is usually determined by professional experts. in case of Inexperienced young researchers, some mistakes may happen in determination of sex estimation. Therefore, there is a need for development of a method to determine sex estimation objectively and consistently even for students. The Diagnosis Sexuelle probabiliste (DSP2) program, which were developed based on more than 2,000 samples known sex from 12 population, is simple and objective method as it determines a sex estimation just by mesauring 10 parameters for hip bone. However, there has been no evaluation whether sex can be determined in Koreans by using DSP2) program yet. The purpose of this study is to evaluate whether the DSP2 program can determine accurately the sex estimation comparing with the non-metric sex estimation results in the hip bone of the Joseon Dynasty. First, three researchers determined gross, non-metric sex estimation of 15 people (n=29) randomly selected from Joseon Dynasty human bone collection as a blind test method. Sex estimation for 15 people were determined as 9 male and 6 female. Based on this result, the sex estimation result by DSP2 program was compared and evaluated the accuracy of sex estimation. When comparing the non-metric sex estimation results, the determination of sex estimation ratio of DSP2 for 10 parameter was 86.2%, for essential 8 parameter was 89.66%, for best 4 parameter was 85%, and for worst 4 parameter was 31.3% (n=9), which was lowest ratio among all 4 set of parameters. Comparing the sex estimation accuracy for 10 parameter with the set of essential 8, best 4, and worst 4 parameter in each, the sex estimation accuracy was calculated as 86.2%, 80%, 31.03%, respectively. DSP2 program for 10 parameter is revealed as a useful program that can be used with high accuracy for sex estimation of hip bone in the Joseon Dynasty. and is also convenient for general user to estimate the sex. This will provide the meaningful basic data for sex estimation of hip bone in the Korean population. However, since the number of hip bones used is not sufficient for generalization, a more accurate evaluation of the DSP2 program will be possible if additional studies are performed with more large scale of samples in the future.
