  • In accident analysis, it is essential to understand the causal pathways of the accident. Although numerous accident models have been developed to help analysts understand how and why an accident occurs, most of them do not include all elements related to the accident in various fields. Thus analysis of human error accidents in railway operations using these existing models may be possible, but inevitably incomplete. For a more thorough analysis of the accidents in railway operations, a more exhaustive model of accident causation is needed. This paper briefly reviews four recent accident causation models, and proposes a new model that overcomes the limitations of the existing models for the analysis of human error accidents in railway operations. In addition, the usefulness and comprehensiveness of the proposed model is briefly tested by explaining 12 railway accident cases with the model. The proposed accident causation model is expected to improve understanding of how and why an accident/incident occurs, and help prevent analysts from missing any important aspect of human error accidents in railway operations

  • 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 purpose of this paper is to consider how to decide the cause of loss or damage to the transport goods when maritime accident occurs. In marine insurance, the underwriter is liable for any loss or damage proximately caused by a risk insured(MIA Art.55). So it is very important to determine the proximate cause of loss or damage to ascertain whether it is to be recoverable under the policy. But there is no definite conception or rule what is the proximate cause. It was left to the tribunal as a question of fact. In this paper, I will suggest the general rules to determine the proximate cause of loss or damage of the transport goods in marine insurance. First, in MIA 1906, there is the rule of proximate causation and it has been established the effective causation by cases since 1918. Second, in Institute Cargo Clauses(B) & (C), there are rules of considerably relaxed standards to determine the causation of loss of or damage using the "attributable to" and "caused by" basis. Third, it is noted, under the complex causation situation, there are difference basises to decide the liability of underwriters between the case of successive occurrence of single risk and the case of concurrent occurrence of several risks. Forth, in practice, it couldn't be ascertained the underwrier's liability by a definite rule and it should be fully considered the circumstances and conditions of the loss.

  • A marine accident is caused various legal liability such as compensation for damages on civil law, responsibility on the Criminal Code and administrative sanctions. The results occurred by any acts is not connected directly to the legal responsibility. As a prior condition for these legal liabilities, it is required the causation between the act caused and the occurrence of the effect. It is very difficult to find out the cause in marine accidents, because of trouble of a proof security, the place occurred, time difference between accident and investigation point of time etc.. However, finding out the correct cause is an element important to prevent similar accident and to determine the liability reverted. The logical concept of the causation is not limited, but there is early necessity to limit it in the liability reverted. Therefore, this study aims to suggest reasonable standard to determine liability reverted in marine accidents.

  • In December 1998, Act on the investigation and inquiry into marine accidents was amended by inserting new Paragraph (2) of Article 4, which states "Where two or more persons are related to the occurrence of a marine accident when the Maritime Safety Tribunal(hereinafter referred to as the "MST") examines the causes of a marine accident as provides for under Paragraph (1), the MST may disclose the extent to which each responsible person is related to the cause of the marine accident". Based on this new Paragraph, the apportionment system of causation ratio in the ship collision was introduced in February 1999. However the apportionment system is adopted 12 years ago, public debate has continued about the positive and negative aspects of the system. Thus some groups advocate the system for the advantages, but other groups argue that this system should be abolished. Therefore, at first, this study analyzes the adopting background and the main reasons of the pros and cons discussion on the apportionment system of causation ratio in the ship collision. Then we conduct a survey analysis to investigate stakeholder's satisfaction of this new system in the ship collision cases. Finally this study suggests the policy proposal to improve the apportionment system of causation ratio in the ship collision.

  • 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.

  • Traffic accidents at signalized intersections have been increased annually so that it is required to examine the causation to reduce the accidents. However, the current existing accident models were developed mainly by using non-linear regression models such as Poisson methods. These non-linear regression methods lack to reveal the complicated causation for traffic accidents, though they are the right choice to study randomness and non-linearity of accidents. Therefore, it is required to utilize another statistical method to make up for the lack of the non-linear regression methods. This study developed accident prediction models for 4 legged signalized intersections with Poisson methods and compared them with structural equation models. This study used structural equation methods to reveal the complicated causation of traffic accidents, because the structural equation method has merits to explain more causational factors for accidents than others.

  • This paper derives security requirements to ensure the safe operation of unmanned ground vehicles from the perspective of accident causation through threat modeling. By analyzing the components of unmanned ground vehicles and identifying potential vulnerabilities in each element, we constructs attack trees that could lead to accidents such as collisions and sudden stops. From these attack trees, security requirements are derived. These requirements are then compared with the security requirements corresponding to accident causation threats as outlined in the UN's document on autonomous vehicle threats and security requirements, UN R155 Annex 5. The comparison highlights how the security requirements proposed in this paper align with those established by the UN. The application of the security requirements proposed in this paper is expected to facilitate the smooth introduction and operation of unmanned ground vehicles.
