Abstract

Kicking someone has clothes on causes direct contact between victim's clothes and skin. This contact makes material exchange from skin to inner clothes. In this study, foot impressions by transferred to cloths from skin would be enhanced by amino acid staining reagent (ninhydrin, 1,2-IND/Zn, DFO). In view of research ethics, we conducted this research with porcine skin instead of human's one. To mimic human's skin condition, applied artificial sweat on porcine skin. According to results, ninhydrin showed high contrast on light colored background and 1,2-IND/Zn, DFO showed high contrast on dark colored background. It showed different results up to kind of fabrics.

발로 사람을 가격하는 행위로 인하여 의복과 사람의 피부 사이에 접촉이 발생하는데, 이 때 피부의 다양한 물질들이 의복 안쪽으로 전이가 일어난다. 본 연구를 통해서, 전이된 물질로 인해서 생겨난 족적을 아미노산 반응 시약인 1,2-IND/Zn, DFO, ninhydrin을 이용하여 현출하고자 하였다. 윤리적인 문제로 인해 사람의 피부와 유사한 돼지 피부를 사용하였으며, 사람 피부 표면과 유사한 조건을 만들기 위해 인공 땀을 적용하였다. 다양한 섬유에 아미노산 시약을 적용해 본 결과, ninhydrin은 밝은 색 표면의 섬유에서, 1,2-IND/Zn와 DFO는 모든 색의 표면에서 족적 현출 결과가 좋았으나 노란색과 빨간색 표면의 섬유에서는 배경과 족적의 대조비가 낮았다. 천 종류에 따라서는 다소 차이를 보인다. 흰 색 면, 면/스판 혼방에서 가장 좋은 결과를 얻을 수 있었으나, 검은색 레이온과 면/스판 혼방에서는 자세한 형태의 족적은 확인이 어려웠다.
