There are insufficient models that find problems and solutions for accident prevention through risk assessment and suggest safe work process and work instruction from foundation works to finish work for accident decrease. This paper presents a quantitative risk assessment model by analysis of risk factors in each process such as earth works, drainage works, pavement works, appurtenant works and etc based on accident examples and investigation on actual condition in roads construction work. In addition, the safety management system was developed to perform risk assessment of construction and use it for effective safety training for labor.

위험관리는 최근 다양한 분야의 산업에 적용 가능한 매우 중요한 토픽이다. 본 연구에서는 기본적인 위험관리의 일반적인 방법론과 새로운 위험관리 평가의 방법론을 제시한다. 위험관리의 실제 적용에 있어서 재정, 보험산업 등의 분야에서는 이미 많은 현실적 방법론들이 개발되었다. 다양한 산업현장에서 발전된 많은 적용사례들이 있으나 여전히 위험관리는 어려운 부분이며, 두 가지 주요한 위험평가 방법론이 시스템 엔지니어링 분야에서 개선되고 발전되어왔다. 그중 하나는 본래의 위험평가의 기본개념을 바탕으로 하여 발전한 것이며 다른 하나는 소프트웨어 엔지니어링분야의 위험평가에서 비롯된 것이다. 규모가 크고 복잡한 시스템에서 효과적인 위험관리는 프로젝트의 최종 목적을 달성하는데 있어서 불확실성에 적절히 대처하여 총 개발비용을 줄이고 목표일정과 성능을 달성하는 효과를 가져온다.

Efforts are continuing to change from fossil fuels used to hydrogen energy society. In order to become a hydrogen society, stable production and real-life applicability are important. As a result, hydrogen generation system linked to fuel cell are being developed. Through this, it is expected that production to power generation will be possible where desired by utilizing the existing urban gas piping network. Hydrogen generation system and hydrogen fuel cell have been subjected to risk assessment and have already been commercialized, but no risk assessment has been conducted on the integrated system linking them. Therefore, it is intended to secure its safety by conducting a risk analysis on the integrated system.

CCS (Carbon Capture and Storage) is considered as the most promising interim solution to deal with the greenhouse gas such as $CO_2$ responsible for global warming. Even though carefully chosen geologic formations are known to contain stored gas for a long time period, there are potential risks of leakage. Up to now, applicable risk assessment procedures for the leakage of $CO_2$ are not available. This study presents a basis for risk analysis applicable to a complex geologic storage system. It starts with the classification of potential leakage pathways. Receptors and the leakage effect on them are identified and quantified. Then, a fault tree is constructed, which yields the minimum cut set (i.e., the most vulnerable leakage pathway) and quantifies the probability of the leakage risk through the cut set. The methodology will provide a tool for risk assessment in a CCS project. The outcomes of the assessment will not only ensure the safety of the CCS system but also offer a reliable and efficient monitoring plan.

K-drone delivery system is a commercial delivery system that ensures compliance with aviation safety. It is equipped with flight routes for automated deliveries and features a drone identification device along with a real-time monitoring system for drone positions. This study proposes the application of an ICAO SMS-based safety management system as an appropriate safety management framework that non-aviation personnel drone operators can adopt. It suggests that applying an ICAO SMS-based safety management system to the K-drone delivery system, similar to Europe and the USA, is valid. To introduce ICAO SMS into the K-drone delivery system, procedures must be established for building a drone safety management system, from business registration to drone operation and training. The main components of the drone safety management system are presented, including 8 items: safety policy and authority and responsibility, risk management, safety assurance, safety promotion, drone control system, drone delivery operation manual, drone maintenance manual, and accident response, incorporating the four fundamental elements of ICAO SMS and European Light UAV operator Certificate standards. Additionally, as a core aspect of the drone safety management system, a seven-step risk assessment procedure is proposed, which includes basic risk identification, hazard identification, risk scenario development, calculation of severity and likelihood, SMS matrix risk assessment, mitigation measures, and implementation determination.

연구목적: 위험성평가의 전산시스템 구축을 통해 건설현장에서 위험성평가 대상 공종 근로자가 쉽게 작성할 수 있고 효율적 위험성평가 활동으로 재해 저감을 기대할 수 있는지의 사례 분석을 목적으로 한다. 연구방법: 작업공종 분류만으로 해당작업의 위험요인과 안전대책을 제공받아 위험추정과 대책수립을 할 수 있으며, 해당작업의 재해사례 제시로 실질적 재해예방 활동이 가능하도록 시스템을 구축하였다. 연구결과: H건설사의 ERP내 위험성평가 전산시스템 구축 이후 현장적용에 따른 년간 환산재해율 변화분석을 통해 국내 건설업의 환산재해율이 증가하는 반면 H건설사의 환산재해율은 감소하였음을 확인하였다. 결론: 위험성평가 전산시스템화를 통해 현장작업 대상 근로자가 위험성평가에 쉽게 접근할 수 있고 해당공정의 위험요인 평가 및 위험예방 대책의 수립이 가능하게 되어, 평가 기간 동안 실제 재해율 감소에 영향이 있는 것으로 분석되었다.

Purpose: This study suggests a method of risk assessment based on RAM analysis in order to reduce the subjectivity. Methods: RAM analysis is used to assessment risk consequence(RC) and risk likelihood(RL). Result: The calculated result of the product, which has higher risk assessment, shows lower MTBF system. Conclusion: Risk assessment based on objective database will provide objectivity and effective quality control.

Fifty chemicals are currently classified as human carcinogens based on epidemiologic and animal data. Humans are daily exposed to them from various sources of exposure via inhalation, dermal contact and oral ingestion. To reduce cancer risk to man, these human carcinogens should be appropriately regulated and monitored environmentally or biologically for routine human cancer risk assessment. A number of mathematical risk assessment models have been introduced, but any realistic and relevant model system is not available for humans. A mechanistic process for human cancer risk assessment was comprehensively reviewed and problems were also discussed. Here, a new conceptual approach using epidemiology and biological human monitoring was suggested for the most relevant method to study human cancer risk assessment.

Risk Assessment, a basis of health and safety management system, is an calamity prevention activity which regularly measure the level of a risk to passively improve potential hazard. A problem, the assessment not being improved to be applied to the construction work site where requires diversity and complexity, causes the assessment to be inefficient to bring quality results. A study on the investigates and compares the surveyed degree of recognitions of workers who works in companies executing the risk assessment By the investigation and comparison, it is expected to bring the better solution for early and efficient application for those companies which are not taking the risk assessment.
