Wood is a tissue produced by the hypertrophic growth of the cambium in woody plants. Along the mesh's holes in the cambium at the transverse section, nutrients and moisture pass through in the longitudinal direction. At the radial section, which is a cross-section along the radial direction, the pit structure acts as a passage for the horizontal movement of nutrients and moisture to adjacent tissues. This structure varies in shape with different species and could be used as a tool for the identification of wood. This study investigates the identification of carbonized wood found in a damaged vehicle and that obtained near a fireside by observing their pit structure with an electron microscope. After washing and drying the two carbonized samples and subsequently observing them with an electron microscope, the similarity in their pit structures was evident. This similarity suggests that the two samples belong to the same species. Typically, identifying wood species requires a significant amount of time and labor for sample pretreatment. Overcoming these challenges, a method using an electron microscope could identify the species through carbonized wood.

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.
