As human factors are the most important cause of construction accidents, it is important to reduce human error in construction work to reduce accidents. However, the error forcing context in organizational situations acts as a factor behind human error. Therefore, fatal construction accidents were analyzed using the m-SHEL model, which can identify the factors behind human errors. Through such analysis, it was found that there are differences in the detailed factors behind human errors according to the type of fatal accidents in construction, This study is meaningful in that it confirmed through accident cases that it is important to understand and respond to organizational situations in order to reduce human error in construction work.

SW 기술이 급변하는 현 시점에서는 SW 관리의 중요성이 인식되어 SW 품질향상을 위한 제도 개선의 일안으로 SW 개발 산출물에 대한 SW 신뢰성 시험이 요구되고 있으나, SW 신뢰성 시험에 투입되는 비용, 시간적 제약 및 휴먼에러 등으로 인해 SW 시험요구조건을 충족하는데 어려움이 있다. 본 논문에서는 문제 해결 도구로써 린6시그마 방법론을 활용하여 SW 신뢰성시험시간을 단축하고 인적오류를 감소할 수 있는 방안을 제안한다.

A forklift is an industrial vehicle with a power-operated fork for lifting and moving heavy loads over short distances. A significant number of accidents are caused by forklifts every year. Most of them are known to be caused by the unsafe acts of workers. However, only a few studies have focused on the risks of forklift work from the perspective of human error. In addition, various methods have been developed to analyze the risk of human error, while it is hard to find studies that directly compare the effectiveness or strengths/weaknesses of those methods. This study aims to analyze risk factors related to unsafe behavior in forklift operations using two representative human error analysis techniques, i.e., .SHERPA and HE-HAZOP, and compare their advantages and disadvantages. The analysis was performed on three main forklift operations ('unloading from the truck', 'moving and loading into the storage', and 'loading on the truck'). As a result, 118 errors and 34 remedial measures were derived by SHERPA. Through HAZOP, 139 errors and 54 measures were derived. The two techniques were compared in terms of the number of results and the method of deriving errors and remedial measures, cause analysis, and risk assessment. This study might be used to reduce human error related disasters in workplaces using forklifts. In order to provide a guide for choosing an appropriate analysis method, more comparative studies on different techniques involving wide range of tasks are needed in the future.

The majority of civil aviation accidents are caused by human factors, and especially for rotary-wing aircraft, accidents often occur in situations where pilots unexpectedly or unintentionally enter into instrument meteorological conditions (IIMC). This research analyzed the error rates of rotary-wing aircraft pilots under low visibility conditions from various angles to gain insights into flight characteristics and to explore measures to reduce accidents in IIMC situations. The occurrence rate of errors by pilots under low visibility conditions was examined using a flight simulator equipped with motion, with 65 pilots participating in the experiment. Flight data obtained through the experiment were used to aggregate and analyze the number of errors under various conditions, such as reductions in flight visibility, the presence or absence of spatial disorientation, and the pilot's qualifications. The analysis revealed peculiarities in flight characteristics under various conditions, and significant differences were found in the rate of error occurrence according to the pilot's qualification level, possession of instrument flight rules (IFR) qualifications, and during different phases of flight. The results of this research are expected to contribute significantly to the prevention of aircraft accidents in IIMC situations by improving pilot education and training programs.

본 연구에서는 플랜트 운영 중 발생할 수 있는 다양한 인적에러를 최소화하고, 예측하기 힘든 사고 발생 시 운전자의 대응과 사고피해 확산을 방지할 수 있는 플랜트 안전훈련 시스템의 설계 방안과 이를 구현하는 플랫폼에 관한 연구를 소개한다. 제안하는 플랫폼은 기존에 활용 중인 플랜트 운영자 훈련 시스템(OTS : Operator Training System)과 비교하여, 관제실 운영자와 현장 조업자가 동시에 상호 유기적인 훈련을 가능케 하는 안전훈련 시스템 개발을 목표로 하며, 추후 서브 시스템의 구현과 통합과정을 통해 본 훈련 시스템 플랫폼의 실용성을 검증할 계획이다.

In 2010 the Manila Amendments established the highest practicable standards for officers and engineers. This amendments includes knowledge, understanding, skills, and proficiency required for a deck officer in terms of the BRM (Bridge Resource Management) to reduce human errors, stated in the International Convention on Standards of Training, Cerification and Watchkeeping for Seafarers (STCW). This paper proposes a proper direction to improve BRM education program in Korea. In relation to the BRM program, its contents and education method were analyzed through the satisfactions survey for cadets and the experienced officers. As a consequence, this research gives several suggestions to improve the current BRM course.

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.
