The Lion Air JT610 accident in Indonesia in October 2018, along with the Ethiopian Airline ET302 accident in March 2019, is an significant aircraft accident that detects defects of the B737MAX aircraft. Shortly after the accident, the FAA prohibited operation of the aircraft. This action has affected the market environment of airlines and aircraft manufacturers around the world. In October 2019, Indonesian Traffic Safety Committee released an accident investigation report for Lion Air JT610, which concluded that the causes of the accident were MCAS design defects, lack of education and training, and errors in the repair process. This paper summarizes the flight control system of the B737MAX aircraft, the causes of the accident based on the final accident investigation report, and provides considerations for aircraft design and retrofit.

교통사고보고서 상의 교통사고 관련 자료 속성들은 그 원인을 파악하고자 하는 전통적인 교통안전 관련 연구에서 뿐만 아니라 최근 자율주행자동차의 안전성 검증 시나리오 개발을 위한 연구에서도 활용될 수 있다. 다만, 교통사고보고서의 자료 속성들은 교통사고 상황 재현 및 시나리오 개발만을 위해 정의된 항목들이 아니므로, 본 연구에서는 확대된 활용성 측면의 교통사고보고서의 개선방향을 제시하고자 한다. 교통사고보고서의 개선방향은 각각 교통사고 발생 이전 상황(pre-crash), 교통사고 중 상황(on-crash), 교통사고 발생 이후 상황(post-crash)로 구분하여 제시하였으며, 각 구분에 따른 추가 자료 항목 또는 자료 처리 방안에 대하여 제시하였다. 또한, 정형화된 형태의 교통사고자료 외에 비정형화된 서술 형태의 교통사고 경위자료로부터 추출 가능한 정보항목들을 도출하여 제시하였다.

공공교통기관인 철도에 요구되는 가장 기본적인 요건은 수송의 안전을 확보하는 것이다. 타 교통수단보다 철도가 비록 안전하지만 대량교통수단에서 일단 사고가 발생하면 그 피해규모는 크다. 철도운영자 및 국가에서는 이러한 철도의 사고발생을 사전에 방지하기 위하여 많은 노력을 기울이지만, 사고를 근절시키는 것은 불가능하다. 따라서 사고발생을 최대한 줄이기 위하여 다양한 방안들이 강구되고 있는데, 본 논문에서는 최근 들어 그 중요성이 부각되고 있는 인시던트 보고제도와 안전문화에 대하여 살펴보고자 한다. 본 논문에서는 미국 및 영국 등 선진외국에서 항공분야에서의 인시던트 보고 제도에 대한 사례를 분석하여 보았으며, 또한 철도분야에서도 인시던트 보고 제도가 도입된 영국사례를 중심으로 이에 대한 분석을 통하여 우리나라에서의 철도분야 인시던트 보고 제도의 필요성과 방향에 대하여 논의하였다. 또한, 사고방지 및 안전향상을 위하여 필요한 것이 철도운영회사 및 관련기관의 철도안전에 대한 문화의식이다. 올바른 철도안전문화의 정착이야말로 가장 확실하게 철도사고를 예방하고 철도안전을 향상시킬 수 있는 방안인 것이다. 따라서 철도기업에서의 철도안전문화에 대한 이해 등에 대하여 본 논문에서 검토하고자 한다.

A contact accident with gantry cranes involving the container ship MV Milano Bridge in Busan New Port took place on 6 April 2020. The report concluded that the pilot unreasonably piloted the ship with impaired maneuverability and without a proper pilotage plan. Analyzing the entire system by CAST model gives a holistic approach in linking all the key components and their roles as well as violations that led to the accident, stepping away from placing the blame on only one component in the system. Furthermore, analyzing the accident as an system theory gives a clear overview of the relationships between system components and how these interactions led to the accident.

The present study has investigated the patterns and the causes of safety -accidents on the accident-data in semiconductor Industries through near miss report the cases in the advanced companies. The ratio of incomplete actions to incomplete state was 4 to 6 as the cases of accidents in semiconductor industries in the respect of Human-ware, Hard- ware, Environment-ware and System-ware. The ratio of Human to machine in the attributes of semiconductor accident was 4 to 1. The study also investigated correlation among the system related to production, accident, losses and time. In semiconductor industry, we found that pattern of safety-accident analysis is organized potential, interaction, complexity, medium. Therefore, this study find out that semiconductor model consists of organization, individual, task, machine, environment and system.

In this study, The behavior of an autonomous vehicle in an intersection accident situation is predicted. Based on a representative intersection accident situation from actual intersection accident database, simulation was performed by applying the automatic emergency braking algorithm used in the autonomous driving system. Accident reconstruction was performed based on the accident report of the representative accident situation. After applying the autonomous driving system to the accident-related vehicle, the tendency of intersection accidents that may occur in autonomous vehicles was identified and analyzed.

Since 1996, like other countries the PSM(Process Safety Management) System has been applied into chemical plant in Korea in accordance with the Occupational Safety & Health Law section 49 paragraph 2. This report is to point out the status and the area of concern, further suggest alternative measures along with the wide and in-depth idea of improvement and recommendation to prevent from industrial accident.

On December 19, 2015, as Article 29-3 (Installation of Accident Recording Devices and Provision of Information) of Motor Vehicle Management Act came into force, In Korea, the EDR (Event Data Recorder) reports are often used for the analysis of various traffic accident cases such as multiple collisions, traffic insurance crimes, and sudden unintended acceleration (SUA), and the others. So many investigators have analyzed the driver's behavior and vehicle situation by comparing the time zero in the EDR report to the actual crash time in dash-cam (or CCTV). Time zero (T0) is defined as the reference time for the record interval or time interval when recording an accident in Article 56-2, Enforcement rule of Performance and Standard for Automobile and Automotive parts. Also in the EDR report, time zero (T0) is defined as whichever of the following occurs first; 1. "wake-up" by an air-bag control system, 2. Continuously running algorithms (by monitoring of longitudinal or lateral delta-V), 3. Deployment of a non-reversible deployment restraint. We have already proposed the "Flowchart & Checklist" to adopt the EDR report for traffic accident investigation and the necessity of specialized institutions or courses to systematically educate or analyze the EDR data. Therefore, in this paper, we report to traffic accident investigators notable points and analysis methods based on some real-world traffic accidents that can be misjudged in specifying time zero (T0).

Children's accident is a largely preventable public health problem. Little is known. however, about population-based incident and outcome of pediatric accident. From 1997.9 through 1998,8. admission data from emergency center in I city were collected. 1418 patient from 0 through 13 years of age were selected. All children with unintensional accidental problems were identified through coded sheet which categorizes epidemiologic characteristics. The specific purposes of this study are analysis about the characteristics of pediatric accidents. And it aims to produce the basic data necessary for accident prevention policy development. The results of this study were as follows; 1. The number of male children$(62.6\%)$ were higher than female children$(37.4\%)$ 2. The age group from 1 to 3 years represents the highest proportion$(45.4\%)$ of every accidents except on traffic accident. 3. The highest proportion of accident were as follows occured during the June-August$(34\%)$, Sunday$(22.6\%)$, and 17-21 p.m. $(37.2\%)$ 4. The main causes of accident include general trauma$(70.9\%)$, environmental accident$(l6.8\%)$. and traffic accident$(l2.1\%)$, 5. Preschool age group represents more than half$(65.4\%)$ of traffic accident. 6. environmental injury includes burns $(46.6\%)$, foreign body$(43.6\%)$, exposure to poisonous materials$(6.3\%)$. and bite(3.3) This results could be used to develope prevention programs and assist in accident prevention system development. And also these data substantiate that accident prevention program decrease safety-related injury rate in preschool age group must be concentrated on enhancing access to a system to have a significant effect. Furthermore, it is necessary for accident prevention. So several suggestions are described here: 1. Development of parent's educational program for accident prevention and safety education should be done actively. 2. Home safety surveillance system should be initiated. 3. The initiation of children's accident report system could be contribute the analysis and the reduction of accident.
