The Marine Safety Culture Index (MSCI) was developed in the year 2018 for objectively assessing the public safety culture levels and for incorporating it as data to spread knowledge regarding the marine safety culture. The method for calculating the safety culture index should include issues that may affect the safety culture and should consist of appropriate attributes for estimating the current status. In addition, continuous verification and supplementation are required for addressing social and economic changes. In this study, to determine whether the questionnaire designed by marine experts reflects the people's interests and needs, we analyzed 915 marine safety proposals. Text mining was employed for analyzing the unstructured data of the marine safety proposals, and network analysis and topic modeling were subsequently performed. Analysis of the marine safety proposals was centered on attributes such as education, public relations, safety rules, awareness, skilled workers, and systems. Eighteen questions were modified and supplemented for reflecting the marine safety proposals, and reliability of the revised questions was analyzed. Furthermore, compared to the previous year, the questionnaire's internal consistency was improved upon and was rated at a high value of 0.895. It is expected that by employing the derived marine safety culture index and incorporating the improved questionnaire that reflects the requirements of marine experts and the people, the improved questionnaire will contribute to the establishment of policies for spreading knowledge regarding the marine safety culture.

SHS(Ship-Handling Simulator) is virtual generation of vessel traffic situation under various environmental conditions. Recent, with the introduction of MSA(Maritime Safety Audit), SHS is being used as a key facility to determine the safety of navigation. However, the current audit techniques specified in the implementation guidance of MSA have been prepared by generalizing common procedures and evaluation methods used by institutions operating simulator systems. Therefore, they need to be reviewed and supplemented. This study analyzed the adequacy of current audit techniques based on the limitations and problems, then suggested the advanced scheme of SHS such as standardization of ship models, standard manoeuvring and evaluation method. The results of this research will contribute to improving the quantification and reliability of audit techniques used in the MSA as well as upgrading of the simulator system.

A mathematical model of responsibility-sensitive safety (RSS) has been proposed as a way to determine whether an autonomous driving accident has occurred. Autonomous vehicles related industry and academia have shown great interest in this model. However, this mathematical model lacks a comprehensive review on whether the model can be used to clarify responsibilities of autonomous vehicles in the event of a traffic accident. In this study, we analyzed the issues that need to be solved in order to apply the RSS model. In conclusion, there is a limit in the equation and the social acceptability of the RSS model. To use the RSS model practically, it is necessary to define the response time of the autonomous vehicle and to measure and control the reaction time value according to the appropriate technology level for each autonomous vehicle.

Recently, expansion of urban and social infrastructures is planned to go through the transfer of military facilities or crossing the infrastructures via underground tunnels. However, when crossing facilities such as ammunition and explosive storages, a high level of safety assessment is required to prevent an accidental explosion of ground ammunition. In this study, a case study was conducted to evaluate the effect of blasting for the construction of tunnel on the ground ammunition facilities. The design section of Sinansan train operated by the Korea Railroad Authority with agreement of the Ministry of National Defense was selected. For the purpose of this study, the vibration velocity due to explosion was predicted by using GTS-NX, a numerical analysis program. Through literature review, it was confirmed that the vibration velocity of 0.2cm/sec can be a safety evaluation standard. These safety evaluation indicators and procedures used in this study can be utilized as an index of safety evaluation in the planning of social infrastructures that cross the ammunition facilities in the future.

ESG (environmental, social, governance) management is being introduced with the goal of sustainable development of the company in risk management, which identifies and judgement various risks that may occur in the industry. In the future, ESG evaluation will be used more as a value judgment tools for corporate sustainability. This ESG evaluation was used to manage the company's accident prevention level. Through morphological analysis of the current ESG evaluation system, it was found that the quantitative 'safety evaluation index' available in ESG was insufficient through analysis of safety evaluation items. In this study, domestic and foreign industrial accident data was analyzed, 'accident contributing factors' that required intensive management were derived, and major safety management items that needed supplementation were selected based on the results. ESG safety evaluation indicators were developed through the process of optimizing the selected items into evaluation factors suitable for 'accident prevention management'.

많은 인원을 필요로 하는 조선업은 선박을 건조하는 현장의 제품들이 복합 공정이면서도 중후장대한 특성을 가지고 있다. 이러한 선박을 건조할 때는 종사하는 작업자 간의 작업 내용에 대한 의논과 방법의 결정에 따른 경험기술의 활용도가 높다. 그래서 작업자별 작업 방법이나 기능의 차이가 많고 그 차이만큼이나 공정 진척이나 품질에 대한 결과도 다르게 나타나게 된다. 하지만 인력 집약도가 높은 조선소 작업인력이 퇴직이나 이직 등으로 발생되는 공백을 내국인으로 채우지 못하고 경험이 없고 소통도 어려운 외국인 작업자로 대체하고 있는 실정이다. 외국계 작업자의 경우 인건비가 낮은 중소기업이나 대기업의 하도급 업체에 고용이 되는데 중소기업의 특성상 기술력의 축적이나 안전작업을 위한 사전 직무교육 등에는 여유가 없어 제한된 기간 동안의 고용이나 단순 업무에만 종사토록 하는 등의 방법으로 활용해왔다. 그러나 외국계 작업자의 고용 비중이 높아지면서 전반적인 생산성의 한계와 불안전 작업에 대한 우려로 그 관심도 높아지고 있다. 외국계 작업자의 경우 생산 현장에서 이루어지고 있는 각종 안전관련 교육이나 행사, 동료간의 소통등에 소외되면서 불안전이 가중되고있고 비자종류에 따라 체류기간이 한정되어 기술력의 유지는 어려운 현실이 될 수 밖에 없다. 이러한 외국계 작업자에게 안전에 대한 수준을 높이기 위한 방안으로 직무별 위험성평가도 작업자의 논높이에 맞게 해야 한다. 현재 활용되고 있는 4가지 위험성평가 방법을 일부 보완하여 안전수준에 맞게 실시하여 작업자 개인별 직무 수행상의 위험성에 대한 이해도가 안전에 미치는 영향을 최소화 하여 안전을 유지시키는 방안을 연구한다. 위험성평가의 취지가 기본적으로 해당 작업자 전원참여라는 중요 요소임을 감안할 때 외국인 작업자의 직무 이해도 점검은 매우 중요하다 하겠다.

The need for risk based safety management has been highlighted in accordance with the growth of aviation industry and public interest in aviation safety. Maintenance, Repair and Overhaul (MRO) in aviation industry is defined to guarantee the safety and reliability. Therefore, state's Civil Airworthiness Authority (CAA) has established safety oversight system dedicated for the development of a healthy MRO industry. The study proposed a risk based oversight system considering Korean environment. Based on literature review including analysis of International Civil Aviation Organization guidance and advance system, we identified two organization risks. Organization complexity can be evaluated in accordance with how large the organization is and how complicated the service they provide are. Organization profile is the organization's characteristic related with safety. This study contributes to improving the process of identifying risk of organization and focusing surveillance capabilities on risk areas for efficient management of CAA's resources.
