The fatality of rollover accidents in motor vehicle crashes is high despite their low incidence. Through the investigation of a 12-passenger van rollover accident in which 10 passengers were involved, we intend to analyze the correlation between the severity of the injury and the position of the occupants. We collected accident information from medical records, interviews, photo-images of the damaged van, field surveys, and the results of the Korean New Car Assessment Program (KNCAP). Based on the occupants' position, we classified injury sites and estimated injury severity. Passenger injury severity was evaluated by trauma score calculation. The initiation type of the rollover accident was passenger side 'fall-over' and the Collision Deformation Classification (CDC) code for the damaged van was 00TDZO3. The crash of the van involved 10 passengers, with an average age of $16.3{\pm}4.2years$. Few of the occupants had fastened seat belts at the time of the incident, and there was no airbag installed. One patient sustained severe liver injury and another was diagnosed with a fracture of the right humerus. The most common injuries were at the upper extremities and the neck. The average of Injury Severity Score (ISS) was $4.8{\pm}5.9$, and the average ISS of right-seated, mid-seated and left-seated occupants was $7.5{\pm}9.3$, $1.5{\pm}0.7$, and $3.3{\pm}2.1$ respectively (p>0.05). In the rollover (to-passenger side) accident of occupant unfastened, the average ISS of right-seated occupants (near side) was higher, but there was no statistically significant difference.

We also investigated the accident scene. Four months later, all occupants of the van, including the driver, were interviewed at their private residences after oral consent, and information on pre-accident seating position and posture, accident situation, and on post-accident rescue work was obtained. The extent of vehicle deformation was expressed in terms of the Collision Deformation Classification (CDC) code provided by the Society of Automotive Engineering (SAE J224).
대상 데이터
A 12-passenger van, which was driving 10 students to a private institute, was running on a narrow one-lane road on a winter night. The paved road was sharply curved, and the van fell over a 1.
A 14-year-old girl was seated on the right in row 4. She was using her mobile phone at the moment of the accident and her arm was snapped to the broken window.
A 15-year-old girl seated on the right in row 2 sustained abdominal pain. She lost consciousness at the accident scene, and was rescued by 119 rescuers.
We analyzed a rollover accident of a 12-passenger van which had 10 occupants aboard at the time of the accident. An accident summary was made by a review of medical records, as well as interviews with the occupants and 119 rescuers. We visited the repair shop which kept the damaged van and made a photographic observation of the damaged van.
A 15-year-old girl seated on the right in row 2 sustained abdominal pain. She lost consciousness at the accident scene, and was rescued by 119 rescuers. When she arrived at the emergency room, she appeared drowsy, and her blood pressure was 90/60 mmHg.
The 28-year-old driver (seated on the left in row 1) had multiple injuries including cerebral concussion, back sprain, and contusions at both shoulders. He alone had a fastened seat belt, but he lost consciousness at the accident scene.
The accident vehicle was a Hyundai STAREX® model which was a 2001 made by Hyundai Motor Company.
They ranged in age from 14 to 17 years, except for the driver, who was 28 years old. There were three female passengers and seven male passengers.
This study was accomplished through review of medical records and interviews with patients of a rollover accident involving 10 passengers in a 12- passenger van. Although we are still far from any general conclusion about injury mechanism at rollover accidents for the lack of nationwide data about school van accidents, especially ones full of passengers at the time of accident, it was evident that the initial rotational torque and the occupant’s position in the rollover motor vehicle accident could make differences to the occupants’ injury severities.

Mean injury severity scores among the driver’s, mid, and passenger’s side were compared using Kruskal-Wallis test (P value**).
Mean injury severity scores between the same row and the other rows were compared using Mann-Whitney test (P value*). Mean injury severity scores among the driver’s, mid, and passenger’s side were compared using Kruskal-Wallis test (P value**).
