Due to the rapid increase in the number of vehicles, the physical and human losses caused by traffic accidents have become serious social problems. In the global trend, there have been active studies conducted on improving safety level of automobile in order to reduce the number of automobile accident. As a result of such research, traffic accidents continue to decline. In the case of South Korea, however, rate of death by automobile accident is 8.5 per 10,000 people and it is a seven rank among the countries in OECD (Organization for Economic Cooperation and Development). This average rate is almost double compared to average automobile accident rate per 10,000 vehicles, of other OECD countries in 2015. Consequently, many studies and policies currently have been conducted and made for increasing safety of pedestrians; however, they are only emphasizing characteristics of pedestrians and drivers. For this reason, this study suggests scenarios for establishment of test standard corresponding with domestic environment and international standard of AEB (Autonomous Emergency Braking) and conducts a real car test by scenarios by setting up a goal with a function for remaining distance after braking and then examine equation by comparing real car tests results and outcome after calculation. This is a theoretical method to predict a relative remaining distance after AEB prior to conducting a real car test for evaluation of safeness of automobile with AEB and it is expected that it solves problem of complication of real car test.

This paper reports an analysis of cyclist accident cases with respect to passenger vehicles on Korean roads. A typology based on Initiative for the Global Harmonization of Accident Data (iGLAD) code book is applied to a traffic accident analysis system(TAAS), which has the real-world crash data on Korea roads, to understand the accident scenarios in more detail and efficiently. Similarly this typology has been used for Germany In-Depth Accidents Study (GIDAS) as well. The accident data analysis with consideration of the typology of Korean road conditions may prioritize traffic safety issues regarding cyclists and is aimed to develop an Automatic Emergency Braking (AEB) system for cyclist. In summary, this paper characterizes and analyzes the scenarios of cyclist crashes with passenger car. The most common accident scenarios on Korean roads are Car-to-Bicyclist Nearside Adult (CBNA) and Car-to-Bicyclist Longitudinal Adult (CBLA), which are more than 86% of total accidents cases. Therefore, it is inferred that AEB cyclist system should include these accident types in the operational design domain to reduce more fatality in Korea.

The advancement of autonomous driving technology is expected to transform cars beyond mere transportation into multifunctional spaces for relaxation and entertainment. As autonomous driving technology becomes more sophisticated, with no need for direct driver control, the interior space of vehicles is anticipated to be utilized for various purposes. Consequently, the importance of car seats, the component most frequently interacted with by passengers during travel, is expected to significantly rise. However, existing car seats are designed according to a seated posture, necessitating verification for passenger safety and seat structure considerations in the context of autonomous driving, where comfortable postures may differ. For these reasons, it is anticipated that the seats of future autonomous vehicles will evolve with the incorporation of additional safety and convenience features. In this study, a three-axis car simulator was employed to investigate seat angles for comfortable postures of passengers in autonomous driving scenarios. Representative postures were identified to enhance passenger convenience. Furthermore, functional design factors contributing to passenger comfort were applied to conduct seat design, seat structure, and collision analysis, with an analysis of the interrelationships among design factors.

In the last year, the number of registered vehicles in Korea surpassed the 15 million mark, and increase in number continuously. Nowdays, this tendency has raised some problems inevitably in the view of expansion of ELV(End of Life Vehicles) and earth environment pollution resulted from it. A foreign country is strengthening law about a car recycling for to solve this problem. Car recycling technology in Japan was introduced in this paper.

자동차산업은 여타 산업에 비해 에너지 사용량이 적고, 주요 작업공정이 기계가공 및 조립 등으로 이루져 있기 때문에 제조공정에서 발생되는 오염물질의 배출이 적어서 저공해형 산업으로 인식되고 있다. 그러나 자동차 그 자체와 관련 산업으로부터 배출되는 환경오염으로 인해 단순히 저공해형 산업으로 분류하는 데는 한계가 있으며, 자동차산업의 환경문제는 크게 자동차 생산 공장의 환경오염, 자동차 운행에 따른 환경 문제 및 리사이클링과 관련한 환경문제로 구분된다.

In this research, safety requirements for guard rail, buffer stop, car stop scotch block, protection device, fire protection facilities, safety siding, escape facilities and inundation protection facilities are studied to establish a standard. First, various kinds of guard rails and their construction methods are investigated. Researches on the level difference of main track and guard rail, joint, length, and fastening force of guard rail are done. Second, the classification of buffer stop and car stop scotch block and its characteristics are examined, and the impact force, speed limit and capacity of buffer stop are summarized. Details of protection device, fire protection facilities, safety siding, escape facilities and inundation protection facilities are also investigated. From this fundamental research results, basic data on the safety facilities of railroad system are established.

Purpose: Motor vehicle crashes are the leading cause of death among children younger than 14 years old. The purposes of this study were to 1) provide a basic overview of child safety seats, 2) review car seat safety usage and misuse, 3) suggest interventions to motivate the usage of child safety seats. Method: The design was a descriptive study with literature review. Previous studies were searched of PUBMED, ProQuest and KERIS. Result: Child safety seats and automobile safety belts protect children in a crash if they are used correctly, but if a child does not fit in the restraint correctly, it can lead to injury. A child safety seat should be used until the child correctly fits into an adult seat belt. Conclusion: To improve child passenger's safety, educational, legislational and environmental enforcements are needed: educational interventions to promote use of child safety seats, strengtened legislation to mandate use of child safety seats, establishment of public acquirements.

이 논문에서는 1년 전에 구입하여 8,500 km를 주행한 차량에서 발생한 화재사례를 분석하였다. 이 차량은 차량이 적색교통신호로 멈추었다가 파란불로 바뀌어 출발할 때 옆 차량이 경음기를 울려서 차량을 세워 확인해보니 엔진 쪽에 불이 붙어 있었다. 이 차량 화재는 배터리 + 단자에 삽입하여 나사로 조이는 고리의 전기적인 스파크로 인해 발생하였을 가능성이 높은 것으로 분석하였다. 그리고 그 고리의 전기적인 스파크는 제조결함으로 인해 발생한 것이므로 화재발생책임은 소유자나 운전자와 관련이 없이 제조자에게 있는 것으로 분석하였다. 이 차량화재의 화재발생책임과 관련하여 법원에서 제조자의 제조결함을 인정하였다.
