dc.description.abstract다양한 물리적 위협으로부터 생성되는 상흔은 위협의 직접적인 요소와 밀접한 관계를 가지고 있다. 본 연구에서는 위협요소와 상흔의 인과성을 파악하기 위해 각 위협요소에 따른 재료거동과 손상을 유한요소 해석하였으며 이를 기반으로 상흔의 양상을 분석하였다. 아울러 통계학적 비교분석방법인 교차상관분석 기법을 바탕으로 위협요소와 상흔의 상관성을 정량적으로 평가하였으며 이를 위해 상흔 형상과 위협체 단면 형상 간의 형상유사도를 도출하였다. 결과를 통해 상흔과 상흔을 생성한 위협체 단면 형상 간의 상관계수가 평균 0.9692로 계산되었으며 따라서 매우 일치함을 확인하였다. 평가기법의 타당성은 비교위협체와의 상관계수를 이용하여 검증하였으며, 결론적으로 상흔을 생성한 위협체의 형상유사도가 비교위협체 보다 더 높게 나타남을 알 수 있었다. 본 연구에서 제시한 위협요소와 상흔의 상관관계 및 형상유사도 평가기법은 향후 과학수사에 있어 물리적 추론방법으로 활용될 수 있을 것으로 생각한다. 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.en_US
