Especially in design of automobile, there are many professional softwares based finite element or multi-body like Madymo, Pam-Crash, Ansys. These program have been released almost every car maker and university. Also in accident reconstruction fields, there are some softwares like PC-Crash, HVE was developed. Unfortunately these programs for accident reconstruction are so general and its input data are so limited, it is very difficult or even impossible to analyze some special cases. In this study, we reconstruct two crime scenes using Madymo program. Although this program was developed for design of car, we apply to crime scene reconstruction. First case is regarding traffic accident. A car was fell under 5m from the road and turn over and then move about 40m. Finally the driver eject from the car. Second case is regarding suicide by hanging. When the police investigate the crime scene at first time, they assume that this crime is a murder case but we carried out autopsy and investigated the crime scene again and analyzed by computer simulation and finally find out this crime is suicide case not murder.

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.

Anomalous origin of left coronary artery from pulmonary artery (ALCAPA) is a rare congenital cardiovascular anomaly. The mortality rate among infants and children without operation has been eighty to ninety-five percents and few patients survive till teen-age or adulthood. This anomaly was detected during elective coronary angiogram in a 32 year-old female patient with atypical chest pain. Reversible ischemia was demonstrated on myocardial 201Tl-SPECT. Coronary angiogram revealed anomalous origin of left coronary artery from pulmonary artery.

The civilization has given us a great comfort and convenience but also it has been threatening our life at the same time. Among these causes of death the traffic accident is the most dangerous thing to threat our life in recent years. According to the report of traffic accident in 2003, the pedestrian to car accident is almost 50% of all types of traffic accident and this percentage is very high level compare to other countries. So this is why we have to focus on this field of accident. This case is as follows, when a pedestrian was riding a bicycle and crossing the road, a taxi hit the bicycle with left outside mirror. The impact was not so severe, the pedestrian stood up by himself. Unfortunately he was impacted once again by a SUV which was following behind the taxi. The evidence were the SUV, clothing and victim. A complete autopsy was performed on the victim. The skull was slightly fractured with line shape and showed hypodermal bleeding under the head skin. The thoracic vertebrae of No. 11-12 was fractured. The cause of death was apparently head trauma and fracture of thoracic vertebrae. But we could not explain why the thoracic vertebrae was fractured without damage of internal organs in chest and abdomen. To analyze this case, we used a dynamic analysis program Madymo V6.2 and applied the Hybrid-III human model. Finally we could prove that if the pedestrian stand against the SUV, the bending moment in spine was raised suddenly at the beginning of impact. At this moment the leg was started to be move to the backward of pedestrian but the upper part of body could not move because of inertia. This bending moment make the spine hyper-extension and this level of moment can fracture the spine enough in low speed of SUV. In this study we analysis the car to pedestrian accident with engineering view and introduce the detail analysis method to reconstruct the accident involving the human trauma.
