초록
법과학 분야에서 수모 또는 인모의 현미경을 이용한 미시적 형태분석은 사건해결에 중요한 정보를 제공해 준다. 털은 주성분이 케라틴이며 세가지 형태학적인 영역 모표피, 모피질, 모수질의 3층으로 구성되어 있다. 본 연구는 편광현미경을 이용하여 모피제품으로 쓰이는 수모 20종을 시료로 형태학적 분석한 결과 모수질의 패턴은 연속적, 비연속적, 존재하지 않는 3가지 패턴으로 분류되었고 모수질의 구조는 불규칙적 결정형, 연속적 단일층형, 연속적 다층형, 그물형 및 격자형구조로 구분되었으며 모수질 표면의 형태에따라 직선형 또는 물결형으로 나뉘어짐을 확인하였다 또한 모수질율(MI), 직경등 형태학적 특징들을 확인하여 향후 모피소재의 동일성 여부 및 동물 종 추정 시 교차 검증을 위한 DB 구축 기초 자료로 활용하고자 하였다.
Abstract
Hair can be important trace evidence at a crime scene. Microscopic analysis of animal hair samples may provide valuable information helpful for criminal investigation in forensic science. Hair microstructure is composed do three layers of keratin: medulla, cortex and cuticle, from the innermost to the outermost. Medulla is described by pattern(continuous, interrupted, absent), structure(amorphous, uniseriate, multiseriate, reticular, lattice) and margin form(straight, scalloped). This study was to provide the basis of database as to animal hair observing the microscopic characteristics such as diameter of the guard hair shaft, medullar pettern, structure, form of margins, medullary index of twenty species animal hair.
