04 Forensic Safety
With the advancement of industrial technology, related facilities are becoming larger and larger and safety accidents are also becoming larger, threatening the lives and property of people. Crime cases are becoming more diverse and advanced, which requires advancement of analysis techniques.
Accordingly, the Forensic Safety Division performs research and development for safety accidents, fire investigations, firearms, explosives, tool marks, footprints, fingerprints, and bloodstain patterns.

Determination of coidentity of morphological evidence
- Trace evidence (tool marks, footprints, fingerprints, bloodstain patterns, etc.) is important for examining the suspected tool and enables to solve cases through analysis for coidentity if the suspected object is presented.
- Research is in progress for improvement of statistical techniques and reliability for coidentity of tool marks, footprints, and fingerprints as well as presumption of perpetrators based on the principles of generation of tool marks and bloodstain patterns
Research on collapse interpretation techniques by external force source (explosion, impact, etc.)
- Recently, the investigation of collapse accidents necessitated not only the analysis on collapse phenomenon by breakage but also identification of design and construction defects, so that the demand for visual reproduction of the collapse process is increasing.
- Establishment of a collapse interpretation model when there is an external force inside a building by applying the interpretation model* research method using AEM that has been developed.
- -It was introduced for the first time in the world for the collapse accident at the Jongno 3-ga Hotel demolition site (January, 2017)
Power evaluation and DB construction for handmade firearms using gunpowder
- Due to the Opaesan mountain shooting case in January, 2016, in which a police officer was killed in the pursuit of his duties, the need to establish a standard for evaluating the power of homemade guns objectively has emerged.
- The standard to quantify the power according to the production material, size of bullet, type and amount of gunpowder used of a homemade gun has been prepared, and the database for the power according to the shape and type of the homemade gun has been established.
