  • 얼마전 언론에 보도된 바에 의하면 반도체 공장들의 순간전압저하로 인한 피해가 몇백억원이 될 정도로 극심하다고 한다. 그러나 이것은 빙산의 일각에 불과하며 순가전압저하에 의한 불량제품의 양산과 그에 따른 국가 경쟁력 저하, 생산기기의 정지와 재기동에 따른 인적, 경제적 손실 등을 고려하면 그 피해액은 엄청나게 불어날 것이다.

  • VTS 협력항해는 수많은 상황판단과 자율적인 행위자들의 의사결정들의 집합체이다. 선박이 서로 영향을 끼치며 상호작용하기 때문에 발생하는 불확실성이 바로 VTS 협력항해가 해결해야 하는 문제 상황이다. 이러한 불확실성으로 인한 항해위험을 극복하기 위해서는 상황자각과 의사결정이 항해사 개별 차원에서 뿐만 아니라 모든 항해자들이 서로 도우면서 VTS 협력항해 전체적인 차원에서 이루어져야 한다는 점을 중점적으로 논의하였다. 본고에서는 해양사고의 원인으로서 조선기술의 미숙보다는 항해관련 인지기술이 더 직접적으로 작용한다는 점을 주장하면서, 더 나아가 기왕에 발생한 해양사고를 상황자각 관점에서 접근함으로써 해양사고의 인적과실과 관련한 심층적인 분석을 할 수 있다는 것을 밝혔다. 항해의 인지과업을 1단계 상황자각에서부터 분산의사결정에 이르는 과정으로 세분화하고, 이런 관점에서 접근함으로써 해양사고의 원인으로 작용하는 인적과실을 심도 있게 분석할 수 있었다. 인지과업의 세분화를 통해서 항해사들이 각 단계별로 에러를 수정할 수 있는 여유를 확보할 수 있게 하고, 사고로 이어지는 인과 고리를 차단하는 한편 보다 안전한 대안을 찾아 실행할 수 있다는 점을 부각시켰다. 이런 연구결과를 항해사의 훈련 과정에 접목함으로써 해양사고의 위험을 획기적으로 줄일 수 있다는 것을 밝히고자 노력하였다.

  • The demolition of domestic infrastructures mirrors other significant construction initiatives in presenting a markedly high accident rate. A comprehensive investigation into the origins of such accidents is crucial for the prevention of future incidents. Upon detailed inspection, the causes of demolition construction accidents are multifarious, encompassing unsafe worker behavior, hazardous conditions, psychological and physical states, and site management deficiencies. While statistics relating to demolition construction accidents are consistently collated and reported, there exists an exigent need for a more foundational cause categorization system based on accident type. Drawing from Heinrich's Domino Theory, this study classifies the origins of accidents(unsafe behavior, unsafe conditions) and human errors(human factors) as per the type of accidents experienced during demolition construction. In this study, a three-step model of QFD-FMEA(Quality Function Deployment - Failure Mode Effect Analysis) is employed to systematically categorize accident causes according to the types of accidents that occur during demolition construction. The QFD-FMEA method offers a technique for cause classification at each stage of the demolition process, including direct causes(unsafe behavior, unsafe environment), and human errors(human factors) through a tri-stage process. The results of this accident cause classification can serve as safety knowledge and reference checklists for accident prevention efforts.

  • The prevention of marine accidents has been a important topic in marine society for long time, and various safety policies and countermeasures have been developed and applied to prevent those accidents. In spite of these efforts, however, significant marine accidents have taken place intermittently. Ship is being operated under a highly dynamic environments, and many factors are related with ship's collision, whose factors are interacting. So, the analysis on ship's collision causes are very important to prepare countermeasures which will ensure the safe navigation. This study analysed the ship's collision data over the past 10 years(1991-2000), which is compiled by Korea Marine Accidents Inquiry Agency. The analysis confirmed that‘ship's collision’is occurred most frequently and the cause is closely related with human factor. The main purpose of this study is to analyse human factor. For this, the structure of human factor is analysed by the questionnaire methodology. Marine experts were surveyed based on major elements that were extracted from the human factor affecting to ship's collision. FSM has been widely adopted in modeling a dynamic system which is composed of human factors. Then, the structure analysis on the causes of ship's collision using FSM are performed. This structure model could be used in understanding and verifying the procedure of real ship's collision. Furthermore it could be used as the model to prevent ship's collision and reduce marine accidents.

  • The purpose of this study is to explore ways of service recovery and procedures through the service failure cases depending on the employee capacity that leads to improving quality of the airline cabin service. This study was tested using the failure case of airline in korea. Since interrupting and discontinuing of customer service affect customer defections, customer satisfaction must quickly respond to the service's error situation. The service of the cabin crew is closely related to the customer's evaluation, the direct connection. Customer's objectives are to meet employee needs for service recovery and to recognize and analyze customer perceptions of human resources services, restore customer expectations and maintain contracts with customers. Therefore, this study proposes a set of strategies for effectively preventing and responding to customer related service failure in the airline cabin service.

  • Early detection of forest fires is essential in preventing large-scale forest fires. Predicting forest fires serves as a vital early detection method, leading to various related studies. However, many previous studies focused solely on climate and geographic factors, overlooking human factors, which significantly contribute to forest fires. This study aims to develop forest fire prediction models that take into account human, weather and geographical factors. This study conducted a comparative analysis of four machine learning models alongside the logistic regression model, using forest fire data from Gangwon-do spanning 2003 to 2020. The results indicate that XG Boost models performed the best (AUC=0.925), closely followed by Random Forest (AUC=0.920), both of which are machine learning techniques. Lastly, the study analyzed the relative importance of various factors through permutation feature importance analysis to derive operational insights. While meteorological factors showed a greater impact compared to human factors, various human factors were also found to be significant.

  • 본 논문에서 교통 상해사고 위험요인들을 정량화하고, 위험요인들 중 교통 상해사고 원인에 가장 근접한 것이 무엇인가를 밝히려고 했다. 사례-조사 연구방법으로는 의학분야에서 많이 사용되는 환자-대조군 방법론을 채택하였다. 서울, 양평, 천안지역을 대상으로 1007년 중 입원환자를 중심으로 채혈조사와 설문조사를 통해 환자국 총 117건과 도로상에서의 일반운전자를 중심으로 호기 알콜테스트와 설문조사를 통한 대조군 총 483건을 수집하여 분석하였다. 승용차의 경우, 교통 상해사고 발생 위험요인으로 27개 항목들이 추출되고, 그 중 '도로의 부적합' 항목(RRR 값:4.057)을 포함 14개 항목이 교통 상해사고 원인에 가장 근접한 것으로 나타났다. 오토바이의 경우, 마찬가지 방법으로 최종적으로 '면허 보유기간' 항목(RRR값:3.733)을 선두로 하여 총 11개 항목이 교통 상해사고를 일으키는 원인에 가깝다는 결과를 얻었다. 또한, 두 경우 모두 인적 요인에 의한 결과피가 크기 때문에 이에 대한 경찰의 지속적인 단속이 필요함을 알 수 있었고, 상대위험도가 높게 나타난 순서대로 교통안전투자 우선순위에 정하면, 효율적인 교통 상해사고 감소를 기할 수 있으리라는 결론에 도달했다.

  • 일반적으로 재해는 물적인 원인이나, 인적인 원인 또는 두 원인이 함께 작용하여 발생한다. 농업기계관련 재해의 원인은 기계의 성능뿐만 아니라 그 기계가 얼마만큼 인간이 쾌적하고, 안전하게 운전조작을 할 수 있는가에 대한 문제에도 직접적인 원인이 있는 것이다. 본 연구에서는 현재 우리나라에서의 농업기계로 인한 재해실태 조사와 외국선진사례의 분석을 통해 농업기계 작업의 특성을 파악하고, 인간공학 측면에서 농작업 및 농업기계에 대한 분석을 통해 위험요인을 도출하여, 발견된 문제점에 대한 개선방안을 마련하고자 한다. 또한 현재 농업기계에 의한 재해현황, 농업기계작업에 대한 안전지침, 설계에 대한 인간공학적인 지침 및 농업기계 재해예방을 위한 정책적 개선대안을 제시하였다. 이러한 연구는 작업자의 기술 및 상황판단, 시계성, 차체진동 및 의자진동, 의자설계, 캐핀 배치 및 설계, 안전장치 및 보호 장치, 작업환경 등을 농업기계 제조회사가 고려할 수 있도록 하는데 큰 도움을 줄 수 있으며 기계의 인간공학적 개선을 통해 안전한 운전조작을 가능케 하여 농업관련재해의 감소와 재해의 사전예방에도 크게 기여할 것으로 판단된다.
