Purpose: No previous study has assessed elderly pedestrian traffic accidents based on a nationwide database. This study aimed to help primary physicians who examine patients in emergency departments to determine and make prompt and accurate treatment decisions. Methods: This study used data from the Emergency Department-based Injury Indepth Surveillance from 2013 to 2017, managed by the Korea Centers for Disease Control and Prevention. Pedestrians aged ${\geq}65years$ were included, and using multivariate logistic regression multiple factors were analyzed to determine their relationship with injury severity. Results: Of 227,695 subjects, 6,498 were included, of whom 2,065 (31.8%) were severely injured. There were more female than male patients in all severity groups. Most accidents occurred in the afternoon and on general roads. In the multivariate analysis, the odds ratio (OR) of injury severity for male pedestrians was 1.165 (95% confidence interval: 1.034-1.313, p=0.012). Older age of patients and the use of ambulances were associated with greater injury severity. The accident time affected the degree of injury severity; i.e., compared to dawn, injury severity increased in the morning (OR: 1.246, p=0.047) and decreased at night (OR: 0.678, p<0.001). A significant difference was noted in the correlation between the type of vehicle causing the accident and the accident severity; i.e., motorcycle accidents had lower severity than bicycle accidents (OR: 0.582, p=0.047). Conclusions: Injury severity was correlated with sex, age, transportation to the ED, TA onset time, and type of vehicle. The study results suggest that injury severity may be positively reflected in initial assessments and overall integrated treatments by physicians and in the related policies.

Head Injuries due to traffic accidents are now the leading cause of death and long term disability in males between 30-50 years. Many patients with head injuries experience mild dysfunction of cognition without major neurosurgical problems, and this may interfere with successful rehabilitation. However, not many studies have been done to investigate the cognitive functioning following mild head injuries. The purpose of this study was to obtain injured patient's dermographic data including medical, neuropsychological and social data, and to investigate the cause of injury and alcohol use at the time of injury. This study focused on the recovery of cognitive function in patients with head injuries and used the Mini Mental State Examination(MMSE) score and its correlation with dermographic and social data. Data on 77 patients with minor head injuries who were admitted to the department of Neurosurgery in 3 and I hospital in Dae Jun from September 1991 to February 1992 were analyzed. The findings of this study are as follows ; 1) Out of the 77 cases reviewed in this study, 62 were male, 15 were female. 2) A higher incidence of injury was observed between 7:00 PM and 12:00 PM. 3) The most common cause of head injury in traffic accidents was pedestrian accidents, and the next most frequent cause was motorcycle accidents. 4) Thirteen of the 77 cases in this study were under the influence of alcohol at the time of injury, and they were all male. 5) The MMSE scores one month after injury and at discharge were significantly lower in patients with head injuries that included skull fractures than in patients without skull fractures, suggesting lower cognitive function in patients with skull fractures. 6) The level of consciousness at admission and three days after admission measured by the GCS for drivers under the influence of alcohol was lower than for sober drivers. The MMSE score was also lower for drunken drivers. 7) The MMSE score one month after the injury had a reciprocal relationship with the age of the patient. 8) The MMSE score one month after the injury and at discharge were highly correlated with the duration of unconsciousness. 9) The MMSE score one month after injury and at discharge were highly correlated with the GCS scores at admission, three days after admission, and one week after admission.

Currently most of the vision-based structural identification research focus either on structural input (vehicle location) estimation or on structural output (structural displacement and strain responses) estimation. The structural condition assessment at global level just with the vision-based structural output cannot give a normalized response irrespective of the type and/or load configurations of the vehicles. Combining the vision-based structural input and the structural output from non-contact sensors overcomes the disadvantage given above, while reducing cost, time, labor force including cable wiring work. In conventional traffic monitoring, sometimes traffic closure is essential for bridge structures, which may cause other severe problems such as traffic jams and accidents. In this study, a completely non-contact structural identification system is proposed, and the system mainly targets the identification of bridge unit influence line (UIL) under operational traffic. Both the structural input (vehicle location information) and output (displacement responses) are obtained by only using cameras and computer vision techniques. Multiple cameras are synchronized by audio signal pattern recognition. The proposed system is verified with a laboratory experiment on a scaled bridge model under a small moving truck load and a field application on a footbridge on campus under a moving golf cart load. The UILs are successfully identified in both bridge cases. The pedestrian loads are also estimated with the extracted UIL and the predicted weights of pedestrians are observed to be in acceptable ranges.

Recently, the industrialized world is suffering from accidents referring from the lack of safety consciousness. According to Korean Safety Regulation Department(1996), students at junior high schools are mostly involved in safety accidents, and this is due to lack of safety consciousness. To prevent these accidents, we need to have safety consciousness and attitude. To make junior high school students who are mostly affected in these accidents act safely, they need to know their level of safety consciousness. The purpose of this study is to develop a guideline of measuring the scale of safety consciousness and analyze the relationship between safety education, accident experiences and safety consciousness. This study is based on a survey of 708 junior high students in Seoul, which was carried out from 12 November, 2001 to 21 November, 2001. 1. The main fields of safety consciousness are home safety, school safety, fire safety, emergency management based on documents. Home safety is again divided into facility safety and livelihood safety, school safety is divided into facility safety, livelihood safety and laboratory safety, traffic safety is divided into pedestrian safety, bicycling safety and public transportation safety, fire safety divided into prevention and escaping during fire breakouts, emergency management safety is divided into general principles and escaping during emergency situations. 2. The primary safety consciousness scale was made according to every field of safety consciousness. A preliminary examination based on the scale and a study of reliance and the factors was held. Based on these results, 27 questions which were concerned to be impairing reliability or lacking in factor were deleted on the secondary safety consciousness scale development The secondary safety consciousness scale which constituted of 73 questions was put into another preliminary study and after analyzing reliability and the factors, 12 questions of low reliabilities were deleted and with these results, the third scale were made consisting of 61 questions. 3. A study based on the third safety scale which is made of 61 questions, were held and with a analysis of the reliability and factors made, the relationship between safety education, accident experience and safety mind were examined. (1) The study of reliability and factors show that Cronbach's coefficient in home safety fields is .7598, in school safety .7924, in traffic safety .8306, in emergency treatment .7775, in fire safety .7247. The questions indicating low reliability were deleted. The factor analysis revealed that home safety is converged on facility safety and livelihood safety. But one question was deleted because it showed incongruence of validity. School safety was converged on facility safety, livelihood safety and laboratory safety. But 2 questions showed incongruence of validity and these were deleted. Traffic safety fields were converged on pedestrian safety, bicycle safety and public transportation safety. One question showing incongruence of validity was deleted. Emergency treatment fields converged on general principles and acting in emergency situations and three questions showing incongruence of validity were deleted. Fire safety was converged on prevention and acting in fire breakouts. Totally, eight questions were removed and the final scale were consisted of 53 questions (2) The 3/sup rd/ grade students scored higher average safety mind scales than 1st graders(p〈.05). And students who had high scores at school tend to have a higher scale than those who do not(p〈.001). (3) Average scale of students who had experience in safety education were higher(p〈.001). Students who had previously been involved in home safety accidents had a low score(p〈.001). This was same to students with experience in school safety accidents(p〈.001). Students with traffic safety accidents and fire safety accidents tend to have a lower scale too(p〈.05, p〈.001).

2003년 1월부터 2008년 6월까지 5년 6개월 동안 대전지역에서 발생한 교통사고와 같은 기간 경찰에서 단속한 통계를 근거로 통계적으로 의미가 있다고 판단된 전체분석, 중앙선침범 분석, 신호위반 분석, 음주운전 분석, 무면허운전 분석, 이륜차 분석, 보행자 분석, 교통사망자 분석 및 교통안전시설 분석, 안전홍보 및 교육 분석, 차량등록 수와 교통사고와의 관계를 SPSS12.0 통계프로그램을 이용하여 분석을 시도한 결과, 의미 있는 결과들이 산출되었다. 교통단속과 교통사고가 일정한 상관관계가 있음이 증명되어 모형이 산출되었고, 교통단속의 효과는 일정한 시간적 간격을 가지고 나타났다. 교통단속과 교통사망자와의 관계는 상관계수가 너무 낮아 통계적으로 유의하지 않은 것으로 나타나 경찰의 단속이 교통사망사고 예방에는 거의 효과가 없는 것으로 분석되었다. 이는 지금까지 추진되어온 교통안전대책의 방향전환이 시급함을 나타내는 것이어서 보다 효과적인 대안수립이 필요하다고 할 수 있다.
