교차상관분석을 통한 위협요소와 상흔 관계 연구

초록

Wound evidence derived from various physical threats is closely related to the direct elements of the threat. To understand the causality of threat elements and wound evidence, a finite element analysis was conducted for material behavior and damage according to the threat elements. Then, the aspect of wound evidence was analyzed based on the results. In addition, the relativeness between threat elements and wound evidence was evaluated quantitatively through a statistical comparison via the cross correlation analysis. Moreover, the shape similarity between the wound and the sectional shapes of the threat was calculated. As a result, it was confirmed that the correlation coefficient between wound evidence and the sectional shape of the threat generating it was 0.9692, indicating a very good agreement. The validity of the evaluation technique was verified by using the correlation coefficient, which was derived from the compared threats. Concludingly, the shape similarity with the threat that caused the wound evidence was higher than the other threats compared. The correlation between the threat elements and wound evidence together with the evaluation methodology of shape similarity proposed in this study could be used as a physical reasoning method in future forensic investigations.
