Abstract

This paper is concerned with air traffic controllers' fatigue and stress that they experience during their daily job particularly as being shift workers. Previous researches reveal that the controllers' fatigue and stress increase by several factors including time spent at work, traffic intensity, visibility, etc. The researches also indicate that air traffic controllers' fatigue and stress can be reasonably surrogated by their heart rate. We set three hypotheses relating the influencing factors and the fatigue and stress represented by the heart rates. Using wrist bands, air traffic controllers' heart rates at various situations are collected at Choongju airport. The hypothetical tests explicitly confirm that the heart rate is highly correlated with the traffic level and the time spent at work. In particular, it be shown that even when handling the same traffic level, air traffic controllers' stress level increases as the time they spent at work increases.

본 연구는 교대근무를 수행하는 항공교통 관제사들의 피로와 스트레스와 이에 영향을 미치는 변수와의 연관성을 규명하는 연구이다. 기존 연구결과에 의하면, 관제사의 피로와 스트레스는 근무경과시간, 관할 항공기의 수, 시정 등과 같은 여러 요소에 영향을 받으며, 또한 관제사의 피로와 스트레스는 심장 박동수에 영향을 미치는 것으로 있다고 알려져 있다. 본 논문에서는 항공교통관제사의 피로와 스트레스에 영향을 주는 요소로 근무경과시간, 관할 항공기의 수, 시정을 설정하고, 각 요소와 피로와 스트레스의 정도를 나타내는 심장박동수에 대한 연구 가설을 설정하였다. 실제 수집된 자료를 활용하여 연구가설을 검정한 결과 항공교통관제사의 심장 박동수는 관할 항공기의 수와 근무시간경과에 영향을 받는 것을 확인하였다. 특히, 동일한 대수의 항공기를 관제하는 경우에도, 근무 시간이 경과에 따라서 관제사의 피로와 스트레스 정도가 증가하는 것을 확인할 수 있었다.
