본 연구는 인간 로봇 상호작용에서 로봇의 사회적이고 관계적인 행동 유형이 인간의 인식에 끼치는 영향을 확인하고자 하였다. 이를 위한 실험에서는 연구 참여자들이 로봇 나오가 인간과 상호작용 하면서 로봇이 오류를 일으키고 신뢰회복을 위한 행동을 영상으로 시청한 후 로봇에 대한 신뢰를 평가하였다. 신뢰회복 행동은 로봇이 오류를 인정하고 사과하는 내부 귀인, 오류가 있었음을 사과하지만 외부로 귀인하는 조건, 오류 자체를 부인, 오류에 대해 아무런 사후 행동을 하지 않는 비 행동 조건으로 설정하였다. 이후 로봇에 대한 인간의 평가를 3가지 측면에서 분석하였다. 첫째, 로봇의 유능함과 정직성에 기반한 신뢰, 둘째 로봇에 대한 지각된 유능함과 정직성, 그리고 로봇의 오류로 인한 신뢰 위반에 대하여 오류의 심각성을 어떻게 지각하는지 탐색하였다. 실험의 결과는 3가지 모든 경우에서 로봇이 사과하지 않을 때보다 사과할 때 오류가 덜 심각하다고 지각하였으며 로봇에 대한 능력 또한 높이 평가하였다. 이러한 연구 결과는 로봇의 행동유형과 오류 극복 방법에 따라 로봇에 대한 인간의 태도가 민감하게 반응 할 수 있다는 근거를 제공하며 로봇에 대한 인간의 지각이 변할 수 있음을 시사한다. 특히 로봇이 스스로의 오류를 인정하고 사과하는 것이 더 신뢰를 높인다는 결과는 로봇이 인간처럼 사회적이고 매너있는 행동을 통해 긍정적인 인간 로봇상호작용을 증진시킬 수 있음을 보여준다.

Performance shaping factors (PSFs) in a human reliability analysis (HRA) are one that may influence human performance in a task. Most currently applicable HRA methods for nuclear power plants (NPPs) use PSFs to highlight human error contributors and to adjust basic human error probabilities (HEPs) that assume nominal conditions of NPPs. Thus far, the effects of PSFs have been treated independently. However, many studies in the fields of psychology and human factors revealed that there may be relationships between PSFs. Therefore, the inter-relationships between PSFs need to be studied to better reflect their effects on operator errors. This study investigates these inter-relationships using two data sources and also suggests a context-based approach to treat the inter-relationships between PSFs. Correlation and factor analyses are performed to investigate the relationship between PSFs. The data sources are event reports of unexpected reactor trips in Korea and an experiment conducted in a simulator featuring a digital control room. Thereafter, context-based approaches based on the result of factor analysis are suggested and the feasibility of the grouped PSFs being treated as a new factor to estimate HEPs is examined using the experimental data.

확장현실의 대중화로 사람의 동작을 실시간 3D 애니메이션으로 구현하는 연구가 활발히 진행 중이다. 특히 Microsoft에서 키넥트 카메라를 개발함에 따라 설비의 부담 없이 간단한 조작만으로도 3D 모션 정보 취득이 가능해져 FBX와 같은 3D 형식과 결합하여 실시간 애니메이션 생성이 가능해졌다. 하지만 키넥트는 마커 기반 모션 캡쳐 시스템에 비해 관절 정보의 추정 성능이 뒤떨어져 낮은 정확도를 보인다. 이에 본 논문에서는 키넥트 카메라 기반 FBX 형식의 모션 캡쳐 애니메이션 시스템에서의 자연스러운 인체 움직임을 구현하고자 관절 추정 오류를 보정하는 두 알고리즘을 제안한다. 첫 번째로 키넥트로 사람의 위치 정보를 취득하고 깊이 지도를 생성하여 인체 부위 길이 제약 정보를 이용해 잘못된 관절 위치 값을 보정, 새로운 회전 값을 추정한다. 두 번째로 기존 및 추정된 회전 값들에 미리 설정된 관절 가동 범위 제약을 적용, FBX로 구현해 비정상적인 동작을 제거한다. 실험으로부터 사람의 동작이 개선되는 것을 확인하였고 알고리즘 간 오차를 비교하여 시스템의 우수성을 입증하였다.

Enhanced machine reliability has dramatically reduced the rate and number of railway accidents but for further reduction human error should be considered together that accounts for about 20% of the accidents. Therefore, the objective of this study was to suggest a new taxonomy of performance shaping factors (PSFs) that could be utilized to identify the causes of a human error associated with railway accidents. Four categories of human factor, task factor, environment factor, and organization factor and 14 sub-categories of physical state, psychological state, knowledge/experience/ability, information/communication, regulation/procedure, specific character of task, infrastructure, device/MMI, working environment, external environment, education, direction/management, system/atmosphere, and welfare/opportunity along with 131 specific factors was suggested by carefully reviewing 8 representative published taxonomy of Casualty Analysis Methodology for Maritime Operations (CASMET), Cognitive Reliability and Error Analysis Method (CREAM), Human Factors Analysis and Classification System (HFACS), Integrated Safety Investigation Methodology (ISIM), Korea-Human Performance Enhancement System (K-HPES), Rail safety and Standards Board (RSSB), $TapRoot^{(R)}$, and Technique for Retrospective and Predictive Analysis of Cognitive Errors (TRACEr). Then these were applied to the case of the railway accident occurred between Komo and Kyungsan stations in 2003 for verification. Both cause decision chart and why-because tree were developed and modified to aid the analyst to find causal factors from the suggested taxonomy. The taxonomy was well suited so that eight causes were found to explain the driver's error in the accident. The taxonomy of PSFs suggested in this study could cover from latent factors to direct causes of human errors related with railway accidents with systematic categorization.

To prevent similar accidents with the basis of industrial accidents already occurred in industrial plants, it would be possible only after true causes are grasped. Unfortunately, however, most accident investigation carried out with the basis of legal regulation failed to grasp them so that similar accidents have been repeated without cease. This research aimed to find out differences between results from conventional accident investigation and those from human error analysis, and to draw out effective and practical counter-plans against industrial accidents occurred repeatedly in an autoglass manufacturing company. As for analysis, about 110 accident cases that occurred for last 7 years were collected, and by adopting the Comprehensive Human Error Analysis Technique developed by the previous researchers, not direct causes but basic fundamental causes that might induce workers to human errors were sought. In consequence, the result showed that facility factors or environmental factors such as improper layout, mistakes in engineering design, and malfunction of interlock system were authentic major accident causes as opposed to managerial factors such as personal carelessness or failure to wearing personal protective equipments, and/or improper work methods.

If an error occurs in the automatic mode when the advanced teleoperator system performs a task in hostile environment then the automatic mode changes into the manual mode. The operation by the control program and the operation by a human recover the error in the manual mode. The system resumes the automatic mode and continues the given task. It is necessary to improve the manual mode in order to make the best use of a man-robot system, as a part of the human interface technique. Therefore, the error recovery task is performed by combining the operation by the control program representing autonomy of a robot and the operation by a human representing versatility of a human operator effectively in the view point of human factors engineering. The geometric inverse kinematics is used for the calculation of the robot joint values in the operation by the control program. The singularity operation error and the parameter operation error often occur in this procedure. These two operation errors increase the movement time of the robot and the coordinate reading time, during the error recovery task. A singularity algorithm, parameter algorithm and fuzzy control are studied so as to remove the disadvantages of geometric inverse kinematics. And the geometric straight line motion is studied so as to improve the disadvantages of the operation by a human.

In this study, the causes of human error were identified through the survey of the drivers of the three organizations: Seoul Metro, Seoul Metropolitan Rapid Transit Corporation, and Korail. It was started with the aim of finding and eliciting causes in various directions including human factors, job factors, and environmental factors. The Cronbach alpha value was 0.95 for the reliability significance of the stress-induced factors in the operational area. The significance probability for organisational factors was shown to be 0.82, and the significance of the sub-accident experience and the driving skill factors in operation was 0.81 In addition, the analysis results showed that stress-induced in the field of driving is higher than the human factors in the reliability analysis. The results of the analysis confirmed that the reliability of the organizational and operational stress-induced factors was higher than other causes. In order to reduce urban railroad accidents, this paper suggests a method for operating safe urban railroad through the minimization human errors.

Purpose: This study investigates human error accidents in the Korean railway sector, emphasizing the need for systematic management to prevent such incidents, which can have fatal consequences, especially in driving-related jobs. Research design, data and methodology: This paper analyzed data from the Aviation and Railway Accident Investigation Board and the Korea Transportation Safety Authority, examining 240 human error accidents that occurred over the last five years (2018-2022). The analysis focused on accidents in the driving, facility, electric, and control fields. Results: The findings indicate that the majority of human error accidents stem from negligence in confirmation checks, issues with work methods, and oversight in facility maintenance. In the driving field, errors such as signal check neglect and braking failures are prevalent, while in the facility and electric fields, the main issues are maintenance delays and neglect of safety measures. Conclusions: The paper concludes that human error accidents are complex and multifaceted, often resulting from a high workload on engineers and systemic issues within the railway system. Future research should delve into the causal relationships of these accidents and develop targeted prevention strategies through improved work processes, education, and training.
