    Firefighters are constantly exposed to dangerous incidents of fire suppression, emergency relief and first aid activities. They go through posttraumatic stress disorder by terrible incidents and disasters, and long-term stress leads to depression threatening their mental health. This study was carried out with the purpose of inquiring into effects of the experience of forest therapy programs of four nights and five days obtained in a psychological and physiological perspective, oriented to firefighters who are mentally and physically tired by stress from urgent and dangerous field works and long-term shift works. 108 firefighters participate in the programs of stress resilience (four nights and five days), the program customized to firefighters held in National Center for Forest Activities. To inquire into psychological and physiological effects before and after the participation in the programs, this study conducted the posttraumatic stress disorder checklist (PCL-5-K) and the test of mood states (K-POMS-B), as well as measured quality of sleep and heart rate variability. For the analysis, mean comparison was made by using a paired t-test. According to the analysis of psychological index, posttraumatic stress disorder reduced from 11.44 (before participation) to 5.14 (after participation), showing statistically significant changes. As for mood states, the score decreased from 6.50 to 5.53. On the other hand, quality of sleep diminished from 33.85 to 28.73, manifesting statistically significant improvement. HRV likewise improved statistically significantly. This study verified that forest therapy programs contributed to relieving stress of firefighters, increasing their physical and psychological stability, and improving quality of sleep. The research results expect that forest therapy programs can be applied as a base data to strengthen stress resilience of firefighters and prevent their posttraumatic stress disorder.

    This study was conducted to verify the perceived restorativeness of citizens visiting forests on social–psychological stress and psychological resilience according to forest space type. The study involved a questionnaire survey conducted on citizens who visited forests between May 1 and July 15, 2020, when social distancing in daily life was being implemented. Three types of forest spaces (urban forest, national park, and natural recreation forest) were selected for the survey. They used the survey results of 1196 people as analysis data for this study. In this study, the PRS (Perceived Restorativeness Scale) and the PWI-SF (Psychosocial Well-being Index Short Form) were used to evaluate perceived restorativeness and social–psychological stress of citizens visiting forests. In the study, the average score of visitors’ perceived restorativeness was 5.31 ± 0.77. Social–psychological stress was found in the healthy group, potential stress group, and high-risk group. These groups made up 8.0%, 82.5%, and 9.5% of the respondents, respectively. Pearson’s correlation analysis between perceived restorativeness and social–psychological stress revealed that the higher the perceived restorativeness, the lower the social–psychological stress. “Diversion Mood”, “Not bored”, and “Coherence”, which are the sub-factors of perceived restorativeness according to the forest space type, were found to have meaningful results for psychological resilience. However, there was no significant difference in the forest space type between “Compatibility” and social–psychological stress, which are sub-factors of perceived restorativeness. In conclusion, the forest space type affects the psychological resilience of those who visit the forest. Urban forests, national parks, and natural recreation forests are places to reduce stress.

    Utilization of forest healing resources for improving the effect of forest healing therapy program

    Today, the population is increasing for forest education and healing purposes. Accordingly, various types of forest education and healing programs (as ‘program’) are being developed and operated. But development of program using forest healing resources (as ‘FHR’) is insufficient. Therefore, this study was conducted to investigate the effects of program using FHR on the improvement of healing effect. The program was improved by the groups of subjects (public officials as ‘G1’, youth ‘G2) using FHR. To find out the improvement of healing effect, the healing effect score (as ‘HES’) of 2018 and the HES of the improved program in 2019 were compared for each subject. G1 used ‘serotonin’ resources to improve ‘Positive Emotion’. G2 focused on ‘Index of Greenness’ to increase the greenness rate. To verify the effect, the pre- and post-survey scale of self-developed 'Forest Welfare Program Effectiveness Survey' was used. To verify the healing effect, paired sample t-test was conducted, and independent sample t-test(one side) was conducted to investigate the improvement of the program. The results of comparing ‘Positive Emotional’ showed that G1-2018(n=30) scored 0.73 and G1-2019 (n=30) scored 1.11. The 2019 program improved FHR by 0.38 points (p<.05).
    The ‘Index of Greenness’ results showed that G2-2018 (n=29) scored 2.21 in 2018 and G2-2019- (n=49) scored 2.94. The 2019 program improved FHR by 0.79 points (p<.01). The utilization of appropriate FHR by target contributed to the improvement of forest healing effects. Therefore, if FHR are utilized to develop and improve programs, it is expected that the forest healing effect will be further enhanced.
