Preliminary Research for Applying Appraisal Techniques to Evaluate the Cause of Skin Injury / 대한법의학회지

In the field of the forensic medicine, deciding the cause of the injury is very important. Forensic doctors usually use their naked eyes, two dimensional photos, the characteristics and the distribution of the wounds for evaluating the cause of the injuries. After body release, forensic doctors not infrequently met the questions from the law enforcement whether the injuries were matched with the new facts or statements given through the progression of the investigation. In the face of answering this question, the information or evidence about the injury is insufficient. New technologies and instruments are being developed and will be helpful for getting the evidence from the human skin injuries. In this preliminary study, authors try to find the usefulness of appraisal techniques(3D scanner, trace evidence, TMDT, alternative light) that are already used for other purposes in forensic field. These techniques have their own merits for preserving the evidences from the injured skin. But further studies and systemic approaches are essential for more scientifically verified evaluation of the cause of the skin injury.

Neck fracture case at low speed in frontal collision / 대한법의학회지

Neck fracture is a major cause of death in traffic accidents and this injury pattern occurred normally in a frontal collision or overturn process. This study investigates a case of neck fracture from a low speed collision. In this case examined, the passenger in the front seat of the car was pulled back and did not have the seat belt on. As the vehicle slipped on a frozen road surface in a downward hill and crashed into the shoulder of the road at low speed. But strangely, even though his neck is fracture there were not any collision marks on interior of the car. This study applied computer simulation to analyze this case and we found out that the upper part of the person was rotated and raised at the time of collision and his neck was fully bent by interference with roof and we also know that the seat belt did not resist the passenger who pulled back his seat.

A Case Study Related to Identifying the Driver of Motorcycle / 대한법의학회지

It is a frequently asked question who was the driver of a vehicle when a traffic accident occur. To give an expert opinion who was the driver of vehicle, expert witness must inspect not only trace evidences remained in vehicle and occupant's clothing but also occupant's injuries. Thus, the collaboration of forensic engineering and forensic medicine is very fruitful in this kind of case. Due to open sitting position of occupants, deciding the driver of motorcycle is a very difficult and case dependent problem and it is very rare that the driver of motorcycle can be decided only by the estimation of occupant's injuries. In this report, we introduce the case that the driver of motorcycle can be decided by the collaboration of forensic engineering and forensic medicine.
