Purpose
The purpose of this study was to assess insomnia and the quality of sleep, investigate the concordance between objective and self-report sleep patterns, and identify physiological, psychological, and situational factors influencing insomnia and sleep quality among firefighters. Methods: A descriptive, cross-sectional study was conducted with 103 firefighters in Korea. The collected data were analyzed using SPSS 23.0. Descriptive statistics, the independent t-test, and hierarchical logistic regression analysis were performed. Results: Insomnia was found in 66 (64.1 %) of the total subjects, and the average quality of sleep (PSQI) was 5.65 (SD=2.57). Total sleep time (401.00 minutes) and sleep latency (21.60 minutes) measured using self-reported scales were longer than the ones measured using objective measurements by approximately 48.70 and 17.10 minutes, respectively. Factors related to insomnia included the role as a paramedic (OR=4.28, 95% CI: 1.02~17.92), anxiety (OR=1.12, 95% CI: 1.01~1.24), and sedentary lifestyle (OR=0.85, 95% CI: 0.78~0.94), and factors related to sleep quality were physical illness status (OR=5.17, 95% CI: 1.53~17.51) and social support (OR=0.86, 95% CI: 0.78~0.95). Conclusion: The results show a high prevalence of insomnia, poor quality of sleep and the discrepancy between objective and subjective sleep patterns among firefighters. To promote sleep quality and health, early screening and treatment of anxiety and physical illness are required. It is necessary to conduct further studies examining the relationship between physical activity level and sleep.

AbstractAbstract PDF
PURPOSE
To understand the meaning of the lived experience with Person under train (PUT) for train or subway operators.
METHODS
The study was built on hermeneutic phenomenological themes from individual interviews of present-day train or subway operators in South Korea. Eight participants were selected to participate in the study. All qualitative data were analyzed using the heuristic guides of Van Manen.
RESULTS
Four fundamental lifeworld themes and eight sub themes emerged in the findings. The first theme of spatiality had‘the place pressed by the darkness’ and ‘the train drags me there’. The second theme, corporeality had ‘a foreboding fear’, and ‘debris of death that gets stuck in the whole body’. The temporality theme had‘distorted time in chaos’, and ‘memory trapped in time’. Finally the last existential theme of relationality had ‘intrapersonal encounter’ and ‘resentment and guilt’.
CONCLUSION
The four existential lifeworld themes provided a framework for in-depth investigation of the operator's “lived experience.” This leads to clear understanding of effects of PUT experience on related individuals. The findings imply that specific active nursing intervention strategies are necessary in order to treat affected train operators, and to prevent further issues in their work and private life.
