초록
본 연구에서는 돼지사체의 노출 정도에 따른 곤충상의 차이와 사체의 분해 속도의 차이를 밝혀서, 사후경과시간의 추정을 위한 법곤충학적 자료를 얻고자 하였다. 또한 법곤충학적 자료에 영향을 미치는 요인에 대해서 고찰하고자 하였다. 이를 위하여 경남 양산의 야산에 2011년 여름과 가을에 각각 나출된 돼지사체와 보온덮개로 감은 돼지사체 1구씩을 설치하였다. 채집된 곤충(4목 371개체) 중 파리목(Diptera)과 딱정벌레목(Coleoptera)이 98% 이상을 차지했고, 모든 사체에서 파리목 검정파리과(Calliphoridae) 곤충이 가장 먼저 출현했다. 위의 두 목의 곤충들이 출현한 기간은 여름에는 사체의 피복 여부에 따른 차이를 보이지 않았으나 가을에는 나출사체보다 감은사체에서의 출현기간이 더 짧았다. 한편 두 계절 모두 나출사체에 비해서 감은사체에서 채집된 곤충의 개체 수가 적은 점으로부터, 사체의 피복이 곤충의 유인성을 감소시키는 요인임이 시사되었다. 사체의 분해 속도는 나출사체의 경우 기온의 영향을 직접 받으며, 감은사체의 경우 강우에 의한 보습성 또는 덮개의 보온성에 의해서 영향을 받음이 밝혀졌다. 따라서 사체의 사후경과시간을 추정할 때는 계절, 강우 등의 환경조건과 사체의 피복 여부 등의 요인들이 반드시 고려되어야 할 것으로 생각되었다.
Abstract
The aim of this study is to offer forensic data for estimating the PMI(post mortem interval), such as differences in the entomofauna and the carrion decomposition rate in the naked and wrapped pig carrions, and to investigate the factors affecting these forensic data. Two pig carrions, naked and wrapped, were placed each in summer and fall, 2011 on a small mountain in Yangsan, Gyeongsangnam-do province. Diptera and Coleoptera occupied about 98% of the insects collected (a total of 371 individuals of 4 orders), and the insect of Calliphoridae (Diptera) was the first visitor in all the carrions. These two dominant insect orders showed up for the similar period of time in both the naked and wrapped carrions during the summer. On the other hand, they appeared shorter in the period in the wrapped carrion than in the naked one during the fall. Further fewer numbers of insects were collected in the wrapped carrions than in the naked ones in both seasons. These facts suggest that wrapping was an important factor to interrupt inducing insects into carrions. As regards the decomposition rate of the carrions, it was directly affected by the ambient temperature in the naked carrions, but was affected by the wrapping effects such as retention of rainwater or thermal insulation in the wrapped carrions. Accordingly it was suggested that the environmental conditions like season and rainfall and the exposed extent of carrions must be taken into consideration to estimate the PMI.
