In order to simplify and reduce the cost of the analysis process for reference samples, STR typing using direct PCR buffer was confirmed. To select an efficient buffer, STR typing was performed using two kinds of buffers. As a result of comparing the STR full profile detection rate and peak height through the heat treatment-based rapid extraction method of the reference samples, it was confirmed that STR GO! was more efficient than Prep-n-Go. In addition, when using commercially available STR and Y-STR analysis kits (GlobalFiler, PowerPlex Fusion, Y23), it was found that there was no problem in result analysis even if the PCR reaction volume for DNA extracted with STR GO! was reduced to 10 uL. However, the detection rate of STR profiles decreased in DNA that had passed time after extraction. To overcome this, the dilution ratio of the PCR amplification product was adjusted and it was confirmed that there was no problem with STR typing even 4 weeks after extraction. This study is expected to be of great help in simplifying and reducing costs of STR typing for reference samples.

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.
