According to SOLAS Convention, a voyage data recorder(VDR) is to be fitted onboard ships to assist in the marine casualty investigation However, a review of Korean Maritime Safety tribunal(KMST), shows that the current VDR systems is inconvenient in practical because the storage format of VDR and the casualty reproduction method are different from one manufacturer to another making it economically and timely difficult for the maritime casualty investigation bodies to carry out investigation in a proper manner. To solve this problem, this paper proposed a newly designed VDR Analysis System(VDRAS), which decodes the voyage data of VDR producea by different manufacturers, reproduces the condition at the time of casualty in an accurate, and performs necessary checks.

This paper reviews the analysis of a given scenario according to the Hybrid Model, and why accident causation models are necessary in casualty investigations. The given scenario has been analyzed according to the Hybrid Model using its main five components, fallible decisions, line management, psychological precursors to unsafe acts, unsafe acts, and inadequate defenses. In addition, the differences between the SHEL and the Hybrid Model, and the importance of a safety barrier during an accident investigation, are shown in this paper. One unit of SHEL can be linked with another unit of SHEL. However, it cannot be used for the analysis of an accident. Therefore, we must use an accident causation model, which can be a Hybrid Model. This can explain the "How" and "Why" of accident, so it is a suitable model for analyzing them. During an accident investigation, the reason we focus on a safety barrier is to create another safety barrier or to change an existing safety barrier if that barrier fails. Hence, the paper shows how a sea accident can be investigated, and we propose a preventive way of avoiding the accident through combining the methods of different models for the future.

The marine safety investigation inquires and concludes the facts and causes of the marine casualties and incidents with the objective of preventing similar roses in the future. Thus, IMO and most states adopt and revise marine safety related conventions and national laws based on the results of marine safety investigation. In particular, IMO recently adopts mandatory IMO Casualty Investigation Code to identify the precise cause of rose with states' cooperation, to report the result of investigation, and to establish new international safety standard helping prevention of similar cases based on the report. The Judgement of the Korean Maritime Safety Tribunal system based on the 'Act on the investigation of and inquiry into marine accidents' is used for the purpose of marine safety investigation in Korea to prove cause of marine accident and to improve marine safety. Therefore, this study examines the Code and compares the Code with the Act to reflect the contents of provisions in the Code into the Act. The study would also be the basic references in relation to revising of marine safety investigation system in Korea Specially, the contents in relation to the independence of investigation authority and mandatory counselling system, and guarantee of seafarers human rights to ensure fairness of investigation would be included.

선박산업에서의 국내외 해양사고 통계에 의하면, 모든 해양사고의 80% 정도가 직접적 또는 간접적으로 관련된 인적요인(Human Factors)에 의하여 발생한다고 보고되고 있다. 이러한 해양사고의 원인을 규명함으로써 유사 해양사고의 발생을 방지하고, 또한, 해양사고 조사에 있어서 공통적인 접근방법의 이용과 국가 간의 협력을 증진시키기 위한 목적으로, IMO(International Maritime Organization)에서는 해양사고 인적요인 조사지침(Guidelines for the Investigation of Human Factors in Marine Casualties and Incidents)을 포함한 해양사고조사코드(Casualty Investigation Code: Code of the International Standards and Recommended Practices for a Safety Investigation into a Marine Casualty or Marine Incident)를 채택하였으며, 동 코드는 2010년 1월 1일 발효되었다. 이에 따라, 해양안전심판원에서는, 3단계 절차로 구성된 인적요인 조사 및 분석 방법론을 제안하고, "해양사고 인적요인 분석 매뉴얼"을 마련하였다. 본 논문에서는, 해양안전심판원에서 제안한 인적요인 조사 및 분석 방법론을 실제 해양사고에 적용하여 인적요인 조사분석 모델의 적용사례를 마련하고, 분석 모델을 검토 및 보완하고자 한다.

This study is a railway accident investigation statistic study with the purpose of prediction and classification of accident severity. Linear regression models have some difficulties in classifying accident severity, but a logistic regression model can be used to overcome the weaknesses of linear regression models. The logistic regression model is applied to escalator (E/S) accidents in all stations on 5~8 lines of the Seoul Metro, using data mining techniques such as logistic regression analysis. The forecasting variables of E/S accidents in urban railway stations are considered, such as passenger age, drinking, overall situation, behavior, and handrail grip. In the overall accuracy analysis, the logistic regression accuracy is explained 76.7%. According to the results of this analysis, it has been confirmed that the accuracy and the level of significance of the logistic regression analysis make it a useful data mining technique to establish an accident severity prediction model for urban railway casualty accidents.

The results of investigations into marine incidents have become an important basis in determining not only possible causes, but also the extent of negligence between the perpetrator and victim. However, marine incidents occur under special circumstances i.e. the marine environment, and this leads to difficulties in identifying causes due to problems in scene preservation, reenactment and acquisition of witnesses. Given the aforementioned characteristic of marine incidents, the International Convention for the Safety of Life at Sea (SOLAS) has adopted mandatory regulations on the carriage of Voyage Data Recorders (VDRs) and Automatic Identification Systems (AIS) for ships of a certain gross tonnage and upwards, so as to reflect recent developments in radio communication and marine technology. Adopted to provide an international standard for investigations and to promote cooperation, the Code of the International Standards and Recommended Practices for a Safety Investigation into a Marine Casualty or Marine Incident (Casualty Investigation Code) recommends member states to build capacity for analysis of VDR data. Against this backdrop, this paper presents methods for efficient investigations into the causes behind marine incidents based on data analysis of VDR, which serves as the black box of ships, as well as digital forensic techniques.
