건설업에서의 재해는 수십 년 동안 다른 산업보다 많이 발생하였기 때문에, 건설업에서의 재해는 반드시 줄여야 한다. 이러한 문제를 해결하기 위해서 작업분류체계(WBS) 및 위험분류체계(RBS)를 제시하였다. WBS와 RBS는 계층적 구조로 작업 및 위험 단위를 쉽고, 빠르게 찾을 수 있다. 그래서 본 연구에서는 건설업에서의 재해를 예방하기 위해 통합 WBS-RBS 프레임워크를 개발하고자 한다. 연구의 순서 다음과 같은 3단계로 진행되었다. ① 데이터 수집 ② 데이터 분류 ③ 통합 WBS-RBS 프레임워크 개발 순으로 진행되었다. 연구의 결과 가장 사고가 많이 발생한 건물용도, 건설공종 및 재해요인을 제시할 수 있었다. 연구 결과를 통해 의사결정자는 건물용도, 건설공종, 및 재해요인의 위험 수준을 고려할 수 있다.

Objective: This paper presents additional considerations related to organization and safety culture extracted from recent human error incidents in Korea, such as station blackout(i.e., SBO) in Kori#1. Background: Safety culture has been already highlighted as a major cause of human errors after 1986 Chernobyl accident. After Fukushima accident in Japan, the public acceptance for nuclear energy has taken its toll. Organizational characteristics and culture became elucidated as a major contributor again. Therefore many nuclear countries are re-evaluating their safety culture, and discussing any preparedness and its improvement. On top of that, there was an SBO in 2012 in the Kori#1. Korean public feels frustrated due to the similar human errors causing to a catastrophe like Fukushima accident. Method: This paper reassesses Japan's incidents, and revisits Korea's recent incidents. It focuses on the analysis of the hazards rather than the causes of human errors, the derivation of countermeasures, and their implementation. The preceding incidents and conclusions from Japanese experience are also re-analyzed. The Fukushima accident was an SBO due to the natural disaster such as earthquakes and a successive tsunami. Unlike the Fukushima accident, the Kori#1 incident itself was simple and restored without any loss and radioactive release. However, the fact that the incident was deliberately concealed led to massive distrust. Moreover, the continued violation of rules and organized concealment of the accident are serious signs of a new distorted type of human errors, blatantly revealing the cultural and fundamental weakness of the current organization. Result: We should learn from Japanese experiences who had taken pride in its safety technology and fairly high confidence in safety culture. Japan's first criticality accident in JCO facility splashed cold water on that confidence. It has turned out to be a typical case revealing the problems in the organization and safety culture. Since Japan has failed to gain lessons and countermeasure, the issue persists to the Fukushima incident. Conclusion: Safety culture is not a specific independent element, which makes it difficult to either evaluate it properly or establish countermeasures from the lessons. It may continue to expose similar human errors such as concealment of incident and manipulation of bad data. Application: Not only will this work establish the course of research for organization and safety culture, but this work will also contribute to the revitalization of Korea's nuclear industry from the disappointment after the export contract to UAE.

These days leakage incidents of toxic materials cause serious effects on the nearby residents as well as the workers around the accidents accompanying massive material losses and human damages through widening influential areas. The risk measure through adequate quantitative analysis as well as the qualitative analysis of the leakage incidents of toxic materials becomes an urgent issue. The damage of the leakage incident on the surrounding area of the dangerous toxic material facilities was calculated quantitatively by adopting several models in this research. First, the calculations of the leakage velocity from the factories were performed by using source model for the assessment of the influential area, and the damages on the nearly residents were calculated by using the dispersion model and the effort model. The probability of the Incidents was computed based on "The manual for classification and priorization of major incidents" published by IAEA( International Atomic Energy Agency ). Above calculated damage area and incident probability were further adopted in this study to induce the individual and societal risk, quantitatively. The calculated data of the real Incident of the toxic material leakage showed reasonable agreements to the actual damage of the incidents, which showed a validity of this study. The result of this study might be a helpful measure for predicting damages and preparing safety systems for similar kinds of incidents.incidents.

Objective: The purpose of this study is to grasp the fundamental structure of incident occurrence in nuclear organizations based on system thinking, and analyze how various causes are interrelated in terms of the causal loop diagram. Background: The recent domestic and overseas nuclear power plant-related incidents and accidents are directly or indirectly associated with safety culture, and thus effective plans for the improvement of safety culture are being called for. While the safety of a nuclear power plant is highly dependent upon technology and equipment, the utilization, maintenance and inspection of the technology and equipment are conducted by workers of the nuclear power plant. Method: Methodology of system thinking perspective using causal loop analysis. Results: As a result of the analysis, first, it turned out that the fundamental cause of incident occurrence in nuclear organizations is time constraint. Second, if a workload of workers increases, their adherence to regulations and procedures comes to be reduced due to time constraint. Third, it is needed, through organizational learning education, to increase actions made from thoughts considering safety as the utmost priority in advance. Fourth, it is necessary to improve professionalism by enhancing educational programs for new workers, and to develop various scenarios with which they can cope with certain situations. Application: This paper provides a base for system dynamics simulation model for future study.

해양환경의 극한 환경조건에 노출 된 고정식 및 부유식 해양구조물의 안전성과 설계비용 효율성에 있어서 파랑-구조물 상호작용의 정확한 예측은 중요하다. 본 연구에서는 규칙파 중 원형 기둥에 대한 파랑-구조물 상호작용을 해석하였다. 3차원 이상유동(two-phase flow)을 해석하기 위해 오픈소스 전산유체역학 라이브러리인 오픈폼을 사용하였다. 4개의 원형기둥이 정사각형 배열을 이루고 있을 때 규칙파의 입사각도에 따른 상호작용을 해석하였다. 원형 기둥 구조물에서의 wave run-up을 입사파의 기울기에 따라 비교하였다. 원형 기둥과 입사파의 상호작용으로 인해 원형 기둥 사이에 높은 파가 생성되는 것을 확인하였다. 본 해석 결과는 구조물과 입사파의 상호작용에 의한 air gap에 대한 연구의 기초자료로 활용될 것으로 기대된다.

Background: Health-care providers typically undergo shift work and are subjected to increased stress. Night shift work may induce disturbed sleep cycles and circadian rhythm. The objective of this study was to explore if night shift workers (NSWs) show an increased risk of abnormal thyroid-stimulating hormone (TSH). Methods: We conducted a retrospective cohort study of 574 employees without thyroid disease and abnormal TSH at baseline who underwent annual check-ups between 2007 and 2016 in a medical center. NSWs were defined as those with working time schedules other than daytime hours. We calculated the incidence rate and estimated the adjusted hazard ratio (HR) for incident abnormal TSH and subclinical hypothyroidism compared with non-NSWs using a Cox regression model. Results: A total of 56 incident abnormal TSH cases and 39 subclinical hypothyroidism cases in NSWs were identified during 3000 person-years of follow-up. In models adjusted for age, sex, obesity, and working departments, we found no increased relative risk for incident abnormal TSH (HR: 0.72, 95% confidence interval: 0.33-1.60) or subclinical hypothyroidism (HR: 0.52, 95% confidence interval: 0.19-1.45) when comparing NSWs to non-NSWs; nor were incidence rates significantly different among exclusively medical employees after excluding administrative staff. Conclusion: In this hospital-based nine-year follow-up retrospective cohort study, NSWs were not associated with increased relative risk of incident abnormal TSH and subclinical hypothyroidism, in contrast to previous cross-sectional studies.

본 연구는 전문가집단을 대상으로 식품안전사고 발생 시 '보도용어'와 '대응용어'에 대한 인식도 차이를 알아보고 용어선택에 따른 피해정도를 개선하기 위한 기초자료를 제공하고자 실시하였다. 식품기업체 식품안전관리책임자 28인과 식품전문기자 17인 총 45인을 대상으로 인식도 조사 및 개선방안에 대해 설문조사하여 통계분석 하였다. 그 결과, 식품안전사건 발생 시 미디어의 영향이 크다는 질문에 기자 70.6%, 기업체 92.9%가 '매우 그렇다'의 응답률을 보였다. 미디어의 자극적인 용어사용이 기업피해의 원인이라는 인식에는 기업체의 83%가 '매우 그렇다', 기자의 70.6%가 '그렇다'로 답해 양측 모두 자극적 용어사용으로 인한 기업피해를 인식하고 있었다. 미디어의 '보도용어'와 정부, 학계 등의 '대응용어'가 소비자의 인식과 사건의 파급에 차이를 주는지를 묻는 질문에 기업체의 92.9%와 기자의 35.3%가 '매우 그렇다'로 답해 두 집단 모두 용어의 차이가 소비자의 인식뿐 아니라 파급을 확대시킨다는데 공통적인 의견을 보였으나 기업이 훨씬 심각하게 느끼고 있었다. '보도용어'의 통일 및 사용제한에 대해 기업체는 전반적으로 긍정적인 입장이고 기자는 긍정과 부정으로 답변이 나뉘어 개인차가 컸다. 식품안전사건 발생시 소비자와 기업체의 피해를 줄이기 위해 기업과 기자, 전문가간 사용하는 용어의 일치 및 차이를 좁힐 수 있는 방안 마련이 필요하다고 사료된다.
