건설재해는 반복재해가 빈번하게 일어나고 재해 발생 시 대부분이 중대재해이므로 안전관리에 더욱더 철저해야만 한다. 하지만 우리나라 건설 산업에서 안전관리 시스템은 관리기법이나 사고예방을 위한 구체적이고 기술적인 수단은 빈곤하며 단순하고 과학적이지 못하다. 이러한 건설 산업에서 안전관리 부분에서 FMEA를 이용하여 안전관리 중점대상 선정 및 중요도의 수치화를 통하여 안전관리 대상에 대한 관리 체계를 확립하기 위한 과학적이고 체계적인 방안에 대하여 연구하였으며 산업안전관리공단의 중대재해 사례를 통하여 실제 사례를 보여주었다.

신뢰성 분석과 고장형태 및 영향분석(FMEA)으로 구성된 신뢰성 설계 절차를 정립하고, 극소형 위성 발사를 위한 공중발사 로켓, 미리내 II의 신뢰도 분석을 수행하였다. 신뢰성 분석 결과를 이용하여 미리내 II가 주어진 운영환경 내에서 임무시간동안 목표 궤도 진입이 가능한지를 분석하였다. 신뢰성 분석 과정에서는 작업분류체계(WBS)를 이용하여 시스템을 목록화 하였으며, 시스템의 작동개념도를 바탕으로 신뢰도 블록 선도(RBD)를 정립하여 신뢰성 구조를 파악하였다. FMEA를 통하여 구성품 및 부품들의 위험 우선순위를 판단하였고 위험도가 높은 구성품 및 부품들을 설계 변경한 결과, 목표 신뢰도를 만족하였으며 위성이 목표 궤도에 안전하게 진입될 수 있는 신뢰성 설계를 수행하였다.

This paper studies on the noise reduction for a small automobile DC Motor (a window motor) using the 6 sigma process. The application of 6 sigma process suggested reliable and valuable statistical data for the quality of the DC motor at the production line. In the measurement step in 6 sigma process. the FMEA(failure mode effect analysis) were used for the detection of noise sources. The application of 6 sigma Process gave not only the improving method for the quality of the DC motor but also the confidence of improvement Itself since it was done on the basis of the test results for a number of DC motors at the production line. Consequently the 6 sigma process was proved very effective for the noise reduction at the production line.

There are now the plating process that have many hazardous factor cause of the using numerous noxious chemical and bad working environments. The purpose of the study is to make a selection of suitable safety evaluation method that can analyze and righteously find with numerous hazardous factor of the plating process. And another purpose is to systematically adjust the risk of plating process by comprehension of the role of process, equipment, and source material. Therefore, these studies are carried out in the following three investigations of this report. The first research understands the injurious human health and environment by analyzing hazardous material based on the MSDS. To evaluate the safety of process and compartment, the second research is proposed the security secure counterproposal by using the FMEA and the HAZOP. The final research is devoted to systematically analyze the hazard by applying for reasonable guide word and doing the HAZOP for hazardous factor in specific process.

This paper studies on the quality problem for the Reley using the 6 sigma process. The application of 6 sigma process suggested reliable and valuable statistical data for the quality of the Relay at the production line. In the measurement step in 6 sigma process, the FMEA(filure mode effect analysis) were used for the detection of problem source. The application of 6 sigma process gave the improving method for the quality of the Relay. Consequently the 6 sigma process was proved very effective for the quality problem reducing at the production line.

Purpose: It can deduce improvement plan that recognizes any risk factors in initial production and mass production by using FMEA and through this process, the appropriate criteria for defence items can be established. Methods: It proposes two methodology - Apply DT/OT data achieved from the beginning mass production stage based on FMECA data of the design stage, to risk management, and risk management plan that reflected line and field faliure data in case of is offered. Results: It proposes the risk management plan through Bayesian method and the risk identification that considered MTTF estimated value in case of initial production process. In case of mass production process, both risk identification by using fault occurrence frequency scores and Byaesian method, In case of the Initial production and mass production, it proposes use both two methods. Conclusion: A more realistic risk identification method can be applied, and by this method the quality improvement effect is expected.

본 논문은 국내에 건설된 충전소를 분석 검토하여 수소충전소에 대한 안전성 평가를 실시함으로써 수소충전 소의 안전성에 대한 확인과 충전소 설치 시 필요한 기준마련에 기초자료를 제공하는 것이 궁극적인 목표이다. 안전성 평가 방법으로 FMEA (Failure Mode and Effect Analysis)를 사용하였고, 충전소를 크게 4개의 공정(제조, 압축, 저장, 충전)으로 분류하였다. 또한 각각의 발견된 위험요소에 S (severity), O (occurrence), D (detection)의 점수를 부여하여 이 세 요소의 곱의 값인 RPN (Risk Priority Number)의 수치를 이용하여 위험의 우선순위를 정하고, 이를 바탕으로 시나리오를 생성하였다. 생성한 시나리오를 기반으로 사고피해영향평가 결과 주요한 사고 유형으로 jet fire와 폭발이 나타났고, PSA (pressure swing adsorption) 공정 feed line에서의 누출의 경우 원료물질에 따라 CO가스의 농도가 상이할 수도 있으나, CO가스중독 위험성을 함께 예측되었다.

As buildings become higher, larger, and more complex, safety issues for construction workers working at such environments become more important. We analyzed 83 critical accident cases reported to the KOSHA(Korea Occupational Safety & Health Agency) for construction cranes by types of cranes and by patterns of accidents and causes. There are more number of accidents related to mobile cranes than that related to tower cranes, but the numbers of dead were similar in both cases. The most dominant cause of crane accidents was "fall of materials". We also analyzed the cases of crane accidents using the FMEA(Failure Mode and Effect Analysis) in order to set up a priority for safety management and also to prioritize research and development items relating tower cranes. In the process, we tried to eliminate subjective indexes such as an expert group survey and use objective and quantitative indexes. As a result, it was found that critical crane accidents occurs most during the "lifting and translating" activity.

Design-build projects were devised to enhance the design technologies of the domestic construction industry and the efficiency of public works, contributing greatly to the development of construction technologies. However, as various stages of the process, such as formulation of basic plans and design documents, and deliberations proceed, claims, including changes in the requirements of clients, and design changes occur. These claims result in the delay in construction and an increase in construction costs. In this regard, this study attempted to identify main claims that delay construction and increase the costs of design-build projects, prevent claims in the future, and improve the efficiency of project implementation.

Hydrogen energy is expanding in range for civil use together with development of pollution-free power sources recently, and it is judged that the use of hydrogen will increase more as a part of carbon dioxide reduction measures according to the Climatic Change Convention. Especially, it is thought that the securement of safety of the used dispenser will be the biggest obstacle in the use of high-pressure hydrogen because the hydrogen station is operated in a high pressure. This study found risks in the process and problems on operation by making use of HAZOP(6 kinds), a qualitative safety evaluation technique, and FMEA(5 kinds), a fault mode effect analysis, for the hydrogen charging system at a hydrogen gas station, derived 6 risk factors from HAZOP and 5 risk factors from FMEA, and prepared measures for it.
