This study was conducted to investigate the possibility of using gaze entropy to evaluate an operator's situation awareness in an emergency accident situation of a nuclear power plant. Gaze entropy can be an effective measure for evaluating an operator's situation awareness at a nuclear power plant because it can express gaze movement as a single comprehensive number. In order to determine the relationship between situation awareness and gaze entropy for an emergency accident situation of a nuclear power plant, an experiment was conducted to measure situation awareness and gaze entropy using simulators created for emergency accident situations LOCA, SGTR, SLB, and LOV. The experiment was to judge the accident situation of nuclear power plants presented in the simulator. The results showed that situation awareness and Shannon, dwell time, and Markov entropy had a significant negative correlation, while visual attention entropy (VAE) did not show any significant correlation with situation awareness. The results determined that Shannon entropy, dwell time entropy, and Markov entropy could be used as measures to evaluate situation awareness.

고속도로를 이용하는 차량이 늘어나고 고령인구가 증가함에 따라 고령자로 인한 고속도로 사고의 피해가 심각해지고 있다. 특히 흐린 날과 야간의 고속도로 교통사고 시 고령운전자의 응급상황이 후속차량에게 전달되지 않아서 2차, 3차 사고로 확대되어 심각한 후유증을 남긴다. 그러므로 고령자의 사고차량과 후속차량들 간의 경제적이고 효과적인 차량간 긴급통신 정책과 그 시스템의 구축이 절실한 상황이다. 본 논문은 고령운전자의 응급상황 시 특수한 비상등 패턴을 활용하여 후속차량에게 전달하여 2차사고 예방 및 긴급구호를 이끌어 낼 수 있는 정책 및 방법을 제안하였다. 추가적으로 적색 제동등을 활용한 차량간 적외선 긴급통신 시스템을 도입하고 RC-Car 형태의 시작품으로 구현함으로써 그 실현 가능성을 확인해 보았다.
