This study examined the burnout intermediates between Fire officials' job stress and Ego-resilience. The objective of this study is to suggest a policy that improves Fire officials' Ego-resilience. This survey was given to 365 fire officials in northern Gyeonggi-do region and the data was analyzed by correlation analysis and regression analysis using SPPS 22.0. The hypothesis is the Fire officials' burnout would be related to Ego-resilience and the effect on Fire officials' job stress regarding Ego-resilience is associated with burnout. The results of the study are that unstable work and inadequate reward affect the measure of burnout, which manifests as sarcasm and job efficacy and reduces the Fire officials' Ego-resilience that results in a positive pointing of the future, emotion control and interest. The meaning of policy is as follows: First, Fire officials need to be given confidence in their work stability. Second, they have to receive social or financial rewards. Third, they require a continuous supporting policy that solves their tension, physical and mental fatigue. Finally, developing diverse educational programs will be needed to promote their Ego-resilience.

This study investigated the impact of the fire disturbance and the pattern of recovery of soil dwelling oribatid mite communities with respect to the resilience from the fire disturbance. Oribatid mites are important decomposer animals of plant debris in soil with the feeding habits of saprophagy and mycophagy. Massive wild fire reduced soil oribatid mite abundance and diversity. The impact varied relative to the intensity of the disturbance. The proportion of the species common to the non-disturbed natural site increased as the time after the disturbance elapsed, which implying some degree of naturalness occurring in reorganization phase of the oribatid mite community. From the sites with different degree of fire impact, we found higher diversity in intermediately disturbed sites than in severely disturbed or non-disturbed site, supporting the intermediate disturbance hypothesis. Also this study showed that with differential degree of disturbance plots, resilience pattern after the disturbance can be explored even with shorter period research relative to the ecological succession of community.

This study was conducted to investigate whether ego - resilience plays a mediating role in the relationship between adult attachment and job stress of fire officers, and to derive implications for job stress reduction of fire officers. A questionnaire survey was conducted for 480 fire officers working in Seoul and Gyeonggi - do, and correlation analysis and regression analysis were conducted using SPSS 21.0. The results showed that there was a negative correlation between instability attachment and job stress in adult attachment, negative correlation between instability attachment and ego - resilience in adult attachment, and negative correlation between ego - resilience and job stress. Adult attachment and ego - The results showed that there was a statistically significant effect on stress. Ego - resilience was found to full mediate the effect of anxiety of adult attachment on job stress and to partial mediate the effect of avoidance on job stress. This study suggests the need to develop a program that can improve ego - resilience considering the importance of ego - resilience and the occupational characteristics of fire officer. This means that the psychological and psychological factors of the individual should also be considered in order to reduce the level of job stress of the fire service personnel.

The purpose of this study was to investigate the mediation effect of the job efficacy on the relationship between job stress and career resilience of fire fighting officers. The participants of this study were 151 Jeju Island local fire fighting officers. The research tools used were job stress scale, career resilience scale and job efficacy scale. The data were analyzed using the SPSS statistical program. Pearson's correlation analysis, hierarchical multiple regression analysis and the Sobel test were conducted. The results of this study are as follows: First, there was a significant negative correlation between the job stress and the career resilience and between the job stress and the job efficacy, while there was a significant positive correlation between the job efficacy and the career resilience. Second, the job efficacy of fire fighting officers was found to have a perfect mediation effect on the job stress and the career resilience. As a result, it was found that job efficiency as a mediator to cope with job stress can improve the work efficiency by improving the career resilience of fire fighting officers. Finally, the discussion and implication are provided based on the results.

Because fire has significant impacts on fauna and flora in forest ecosystems, as well as socioeconomic influences to local community, it has been an important field of study for decades. One of the most common ways to reduce fire risk is to enhance fire-resilience of forest through fuel treatments including thinning and prescribed burning. Since fuel treatment can't be practiced over all forested areas, appropriate and effective strategies are needed. The present study aims to look at the relationship between spatial characteristics of forest structure measured with landscape pattern metrics and burn severity to provide guidelines for effective fuel treatments. Samchuck fire was selected for the study, and 232 grids covering the study areas were generated, and the grid size was 1km. The burn severity is measured with dNBR derived from satellite imagery, and spatial characteristics of forest structure were measured using FRAGSTATS for both landscape and class levels for each 1km grid. The results of this study strongly indicated that heterogeneity in composition and configuration of forests may significantly reduce burn severity. By enhancing heterogeneity of forests, fuel treatments for fire-resilience forest could be more effective.

This study examines the effects of job stress on fire-fighters' job performance on negative job factors, job burnout, and positive job factors, job satisfaction, respectively, and by examining whether resilience has a modulating effect in these influence relationships. This was done to provide useful information for planning management strategies. The analysis was done by regression analysis of data collected through a structured survey of 239 fire-fighters, and the moderating effect was confirmed by calculating and applying the interaction term. For the analysis, a structured questionnaire survey was conducted on 239 fire-fighters. As a result of the analysis, it was confirmed that job stress and job burnout of fire-fighters were low, job satisfaction was normal, and resilience was above average. Also, there was no significant difference in resilience according to demographic characteristics, and it was found that job stress had a positive(+) influence on job burnout at a statistically meaningful level, and a negative(-) influence on job satisfaction. In addition, it was found that impulse control power and cause analysis power had a moderating effect in the influence relationship between job stress and job burnout, and impulse control power had a moderating effect in the influence relationship between job stress and job satisfaction. Based on these results, it was proposed to preemptively apply various resilience programs suitable for the situation of fire-fighters, enhance emotional competence, and introduce coaching personnel to help self-reflection.

The amount of damage and the area of damage to forest fires are increasing globally, and the effectiveness analysis of the restoration method after the damage is performed insufficient. This study calculated the area of forest fire damage was calculated using Sentinel-2B satellite images and stack map and the intensity of forest fire damage is analyzed according to the forest type. In addition, the vegetation index was calculated using various wavelength bands. Based on the results, the vegetation resilience by the restoration method was quantitatively. As results, areas with a high proportion of coniferous forests suffered high intensity forest fire damage, and areas with a relatively high ratio of mixed and broad-leaved forests tended to have low forest fire damage. Also, artificial forests showed a recovery of about 92.7% compared to before forest fires and natural forests showed a recovery of about 99.6% from the result of analyzing vegetation resilience in artificial and natural forests after forest fires. Accordingly, it was confirmed that natural forests after forest fire damage had superior vegetation resilience compared to artificial forests. It can be proposed that this study is meaningful in providing important information for efficiently restoring the affected target site and the selection criteria for trees to reduce forest fire damage through the evaluation of vegetation resilience by the intensity of forest fire damage and restoration methods.

The reliability of structures is affected by various impacts that generally have a negative effect, from extreme weather conditions, due to climate change to natural or man-made hazards. In recent years, extreme loading has had an enormous impact on the resilience of structures as one of the most important characteristics of the sound design of structures, besides the structural integrity and robustness. Resilience can be defined as the ability of the structure to absorb or avoid damage without suffering complete failure, and it can be chosen as the main objective of design, maintenance and restoration for structures and infrastructure. The latter needs further clarification (which is done in this paper), to achieve the clarity of goals compared to robustness which is defined in Eurocode EN 1991-1-7 as: "the ability of a structure to withstand events like fire, explosions, impact or the consequences of human error, without being damaged to an extent disproportionate to the original cause". Many existing structures are more vulnerable to the natural or man-made hazards due to their material deterioration, and a further decrease of its loadbearing capacity, modifying the structural performance and functionality and, subsequently, the system resilience. Due to currently frequent extreme events, the design philosophy is shifting from Performance-Based Design to Resilience-Based Design and from unit to system (community) resilience. The paper provides an overview of such design evolution with indicative needs for Resilience-Based Design giving few conducted examples.
