      A large body of data shows that fatigue impairs human performance. Additionally, many studies&#xD;
      have provided evidence that fatigue can worsen mood, as indicated by increased scores on&#xD;
      measures of depression, anxiety, confusion, and anger. In this context, we examined&#xD;
      attentional and emotional changes in physicians after they completed an overwhelming&#xD;
      outpatient clinic in a university-affiliated tertiary referral hospital in South Korea.&#xD;
