The purpose of this study is to investigate the current status of firefighting seatbelt use and factors affecting the wearing seatbelt of firefighters. The seatbelt use of citizens was also studied for comparative study. Two T-tests were conducted to confirm the characteristics of firefighters' safety belts wearing firefighters. As a result, there was a statistically significant difference, on seatbelt use in general vehicles, between firefighters and citizens. And a significant difference between fire vehicles and general vehicles, on firefighters' seatbelt use, and the average was lower in fire vehicles. Factor analysis, reliability analysis, correlation analysis and multiple regression analysis were conducted to 10 influential factors affecting seatbelt use of firefighters'. And factor analysis and reliability analysis revealed two major factors (Physical factors, Learning factors). In multiple regression analysis, it was confirmed the two independent factors had a positive effect on the dependent variable, the rate of seatbelt use of firefighters'.

Development in vehicle industry could increase interest in children's safety recently. However the research of children safety is not being conducted as many as that of adult's. Especially the basic study for the vehicle crash on-board children was not much. This study focused on the effect of seatbelt anchorage points to evaluate children's safety in frontal crash. The current regulation of the seatbelt anchorage points is suitable for ranged from female 5% to male 95%. The assessment of children's safety at buckle up of no used CRS(child restraint system) was performed using frontal sled tests. The frontal crash pulse in sled tests was designed to the average of about 30 KNCAP frontal crash pulses. To reduce number of experiments, DOE is used. The Q6 child dummy and standard seat in UN R 129 were used. According to the analysis of test results, children's safety has been influenced by the points of seatbelt anchorage.

Motorized retractors enhance the safety of passengers by removing the slack of webbing and by holding upright driving position. Reliability of a driving mechanism that includes one-way clutch between the driving motor and webbing is directly linked to the safety of passenger. In this research, conditions for locking one-way clutch and also conditions for sustaining locking are theoretically investigated. the operation of a motorized retractor under realistic conditions is simulated in order to validate the proposed retractor design.

Frequently faced with dangerous situations, for evidentiary purpose in case of civil and criminal liability challenges, car drivers in Korea have been armed with so-called 'black boxes'; however, which are just video recorders in vehicles rather than real 'black boxes' that are equipped in the airplanes. In the United States, they are called EDRs(Event Data Recorders), more technically, which means that they record data of events happened while driving, such as velocity changes, airbags deployment, seatbelt wearing etc. just like in the airplanes. EDR technology is quickly becoming more advanced, more widely available, and less expensive; however, new concerns are emerging : the privacy of drivers. In U. S., vehicle manufacturers and insurance companies and the governmental agencies including the courts and legislatures are the main parties in terms of the EDR concerns. In order to determine the best way to regulate EDR, it is necessary to balance all the merits, such as safety, privacy, truth, justice and efficiency, to support a legal framework regulating the EDR concerns. This article, in light of the regulation of EDR and experience therof in the United States, examines EDR technology itself, particularly with respect to the automobile industry, describing its history, its current state, and trends that may change it in the future; and explains how the National Highway Transportation Safety Agency (NHTSA), legislatures, courts have approached EDR data. At the early stage of regulation on EDRs in Korea, examining U. S. legal framework and usages would help for successful establishment of legislation and regulation.

교통사고로 인한 인체 상해를 최소화할 수 있는 안전벨트의 착용이 전 좌석에서 의무임에도 불구하고, 안전벨트를 착용하지 않은 교통사고 사상자수는 여전히 많은 비율을 차지한다. 주행차량 내 전 좌석 안전벨트 착용 검지시스템은 탑승자의 안전벨트 착용 여부를 판단하고 착용을 유도하는 시스템으로 안전벨트 미착용 사상자수 감소를 위한 유용한 기술적 대응방안이 될 수 있다. 본 연구에서는 첫 번째로 순서형프로빗 모형을 활용한 교통사고 상해심각도 영향요인 평가를 통해 시스템 도입에 대한 타당성을 제시하였다. 분석결과, 안전벨트 착용 여부는 교통사고 상해심각도에 통계적으로 유의한 영향을 미치며 안전벨트 착용 시 사망 및 치명상에 이를 확률이 0.054배 감소하는 것으로 나타났다. 두 번째로 안전벨트 및 교통사고 상해와 관련된 선행연구를 기반으로 메타분석을 수행하여 시스템 도입 시 기대되는 사고심각도 감소효과를 추정하였다. 사고심각도 감소효과 분석결과, 안전벨트 착용 시 사망사고가 63.3% 감소할 것으로 분석되었으며 앞좌석은 75.7%, 뒷좌석은 58.1%의 사망사고 감소효과를 갖는 것으로 나타났다. 마지막으로 메타분석 결과와 교통사고 통계자료를 기반으로 시스템 도입 시 기대되는 교통사고 사상자수 감소효과를 도출하여 시스템의 교통안전 측면 효과를 분석하였다. 시스템 도입률이 증가함에 따라 안전벨트 미착용 교통사고 사상자수가 감소하였으며 시스템 도입률이 60%일 경우 사망자수는 현재 대비 3배 이상 감소할 것으로 예상되었다. 분석결과를 활용하여 안전벨트 착용률을 높이고 사고심각도를 저감시킬 수 있는 시스템 운영 방안을 제시하였다.
