1,2-Indanedione/Zinc로 현출한 다리미와 챔버의 비교에 관한 연구
A Study on the Comparison of the Development of Ironing Press and Humidity Chamber with 1,2-Indanedione/Zinc
Fingerprints are known as important evidence for the suspect identification, and fingerprints should be developed appropriately depending on the properties of the evidence surface. In this study, Artificial fingerprints deposited on a copy paper were developed by using the 1,2-IND/Zn, heat treatment was performed through an ironing press and a humidity chamber. The purpose of this study is to find a device is more better. The conditions of an ironing press were set to 10 seconds, 160°C based on previous studies. The conditions of a humidity chamber were set to temperature (80°C, 100°C), relative humidity (0% RH, 65% RH), heat treatment time (10 minutes, 20 minutes) based on previous studies. As an evaluation method, there was no difference in the fingerprint evaluation using human visual system, so this study used a contrast index. As a result, except for certain conditions (20 minutes, 65% RH, 80°C), the overall contrast index tended to decrease as the temperature decreases. Contrast index of 65% RH at 80°C tended to increase significantly over time, but 0% RH at 80°C tended to decrease over time. Confirmed the optimal conditions of an ironing press was 10 seconds, 160°C and the optimal conditions of a humidity chamber was 80°C, 65% RH, 20 minutes. Fingerprints of the two devices were showed the shape, location, minutiae of the ridge clearly, so an ironing press is heat treatment device that has no problem to use. But it is thought that the use of a humidity chamber should be considered for better development.

법과학 분야는 사회정의 구현에 있어 크나큰 가치가 있음에도 불구하고 우리나라에서는 이 분야에 대한 인식이 미흡하여 선진 외국에 비해 침체되어 있는 실정이다. 이에 우리나라에서도 법과학 분야와 관련 있는 학계, 연구기관, 수사기관 등 유관 단체들로 구성된 한국 법과학회를 창립하여 이 분야를 활성화 시켜 과학수사를 한층 더 발전시키기 위함을 목적으로 한다.
