The accidents are often resulted from multiple causes with hardware failure and human errors. So to ensure the safety of rail operation, human error should be prevented effectively. The purpose of this paper is to present an analysis system on factors of influencing human error in korean rail industry especially for engine driver and train despatcher. To achieve it, ESFs(error shaping factors) classification system was derived from several PSFs(performance shaping factors) classification system. Based on them, two kinds of questionnaires for engine driver and train despatcher each were developed. Then Analytic Hierarchy Process (AHP) methodology was used to evaluate what factors were critical to human error.

Human error is one of the major contributors to the railway accidents or incidents. In order to develop an effective countermeasure to remove or reduce human errors, a systematic analysis should be preferentially performed to identify their causes, characteristics, and types of human error induced in accidents or incidents. This paper introduces a case study for human error analysis of the railway accidents and incidents. For the case study, more than 1,000 domestic railway accidents or incidents that happened during the year of 2004 have been investigated and a detailed error analysis was performed on the selected 90 cases, which were obviously caused by human error. This paper presents a classification structure for human error analysis, and summarizes the analysis results such as causes of the events, error modes and types, related worker, and task type.

최근 국내의 해양사고 원인은 인적 오류에 의한 사고가 약 80% 이상으로 제시되고 있다. 이 중 가장 높은 사고 원인은 '경계 소홀'(43.0%)로 전체 사고의 절반에 이르고 있다. 따라서 관제 및 항해 업무에 대한 집중력 향상과 점유적 관리에 대한 연구가 필수적으로 요구된다. 이에 본 논문에서는 선박이 관제 영역 내에 있을 경우 관제사에게 통보하여 관제 집중도를 향상시키고, ASM (Application Specific Message) 서비스와 연계하여 VHF음성통신으로 인한 정보 부재의 취약성을 보완하여, 안전한 항해 및 관제의 효율성을 제공하는 방식을 제안하고자 한다.

본 논문에서는 한-IAEA 전면안전조치협정에 의거해 원자력사업자가 핵물질 정보를 작성하고 있는 계량 관리보고시스템을 개선하기 위하여 GUI 기반 시스템 구축 방안을 제안하였다. 현재 사업자는 전면안전조치 협정 보조약정 Code 10에 기술된 양식에 따라 정해진 Keyword나 Code를 통해 핵물질의 수량, 물리적 및 화학적 형태, 재고변동형태 등을 계량관리보고서에 작성하고 있다. 사업자가 제출한 계량관리보고서를 통해 국제원자력기구는 국내에 존재하는 전체 핵물질 현황을 준 실시간 파악할 수 있고 현장 사찰을 통해 신고내용을 검증한다. 2022년 말 기준 국내에는 31개의 원자력 시설과 292개의 소량핵물질 이용기관이 계량관리 보고대상 사업자로 존재하며 계량관리보고서 작성 규칙을 숙지하기 위해 많은 노력을 기울이고 있다. 본 논문에서 제안하는 GUI 기반 시스템 구축 방안을 활용한다면 원자력사업자의 계량관리보고서 작성 부담을 경감시키고 인적 오류를 사전에 방지할 수 있을 것이다.

국립중앙박물관에서는 국공사립 박물관 및 미술관 등의 소장품을 체계적인 관리지원을 위하여 문화유산표준관리시스템을 개발 및 배포하고 있다. 문화유산표준관리시스템의 자료등록 방법은 크게 두가지로 나뉘고 있다. 첫 번째는 소장품등록의 웹페이지화면에서 할 수 있으며 두 번째는 엑셀양식을 통한 일괄등록이다. 본 논문에서는 엑셀양식을 통한 일괄등록의 경우에서 별도의 웹페이지를 작성하여 자료입력방식에서 생길 수 있는 인적오류를 최소화하는 방법을 제시한다.

This study focuses on the margin of human error when a navigator is embarrassed by the psychological fear of collision in a close-quarter situation (CQS) and is unable to perform as per the prescribed collision avoidance measures. The purpose of the study is to identify the effects of the navigator's personal characteristics or factors in relation to on-board career (OC), license rating (LR), and age on the perceived collision risk (PCR) in CQSs. In order to obtain quantified data regarding the collision risk perceived by the navigator in four typical CQSs between their own ship and a target ship, this study measured and collated the heart rate variability of 30 navigators on their own ship when two ships approached each other at a speed of 10 knots from 2.5 nautical miles to a collision situation. According to a multiple regression analysis of the measured values, the navigators' OC and LR factors had negative effects on the PCR, while the age factor had no significant effect on PCR. The t-test results showed that the PCR value was significantly higher for navigators with an OC ≤ 4 years than for those with an OC ≥ 5 years, and the LR factor was significantly higher for a class 4~6 group than for a class 2~3. This finding may be applied to the development of collision risk warning systems, particularly for navigators.

Special railway vehicles for track maintenance are equipped with a tamping device that adjusts various track trajectories to reduce the vibration of rolling stock and improve ride quality during trains passing over a track. The development of a simulator that can confirm the error of the actual tamping work is important for reducing human error in the linearization of the track misalignment. In this study, to improve the reality and training effect of conventional 2D simulator, 3D simulator modeling was implemented for tamping work of special railway vehicles in virtual space. The problem of buffering during high screen quality of tamping work was solved using the Unwrap UVW mapping technique of a low polygon extracted from high quality polygon modeling. The human error in the training of the tamping work was detected by the principle of circle and square collision when the tamping tyne and the sleeper collided. In addition, vibration of the driving chair was generated at the same time as the collision, and the number of the sleeper strikes is displayed on the simulator exercise screen. Owing to the scattering of railway ballast protruding from the sleepers, which had a serious effect on the safety of the vehicle, the gravel bouncing effect of the tamping unit was applied.

The purpose of this study is for Human error prevention to acquire Collision Risk Perception Index (CRPI) sensed by the Officer Of the Watch (OOW) when the approaching distances are reduced in six types of ship encountering situations (Head on, $045^{\circ}$, $090^{\circ}$, $135^{\circ}$, Overtaking, Overtaken) between own ship and a target ship and then to predict CRPI fitting coefficients with polynomials in the curve-fitting process. CRPI acquisition experiments are carried out on two coast-guard ships and with the total of 30 crew members. Analysing results shows that CRPI data have goodness of fit to the six types of encountering situation. Futhermore, the One-Way ANOVA results show that CRPI has a negative affect to the OOW's age, career and license grade as the approaching distances is reduced. The availability of CRPI curve fitting with 3 degrees of polynomial was testified through the RMSE as 1.19 to Head on, 0.87 to $045^{\circ}$, 0.81 to $090^{\circ}$, 0.71 to $135^{\circ}$, 1.29 to Overtaking and 0.87 to Overtaken.
