Purpose : The purpose of this study was to provide appropriate direction for triage education by investigating the knowledge level of triage in 119 EMTs before and after the triage education. Methods : The questionnaire was filled out by newly assigned 33 EMTs in the fire service academy in I metropolitan city from November 1, 2013. The data were analyzed using SPSS WIN 21.0 program. Results : The lowest knowledge level by 119 triage was the potential emergency related question, but that by case-based triage was the semi-emergency related questions. The knowledge score by case-based triage before education was 51.14 points. This was lower than knowledge score by 119 triage, that is, 75.70 points. After education, the knowledge level by 119 triage was significantly improved(p =.000). However, there was no significant difference in the knowledge level by case-based triage(p =.236). Conclusion : It is necessary to provide systematic and periodic education and training for 119 EMTs toward triage to improve triage accuracy and efficient circulation of the emergency medical service system. Especially, it is very important to provide case-based triage education for field application.

Purpose: This is a descriptive research study that aims to identify factors affecting fatigue by examining the degree of emotional labor, job stress, and fatigue of 119 emergency medical technicians (119 EMTs). The correlation between emotional labor, job stress, and fatigue was also confirmed. Methods: A total of 139 EMTs working in the Daejeon area participated in this study. Data were collected from July 6-15, 2021. Results: When the number of dispatches was high and the job was dissatisfying, the degree of emotional labor was high. In addition, the shorter the work experience and the lower the job satisfaction are, the higher the job stress is. The degree of fatigue was significantly higher in female than male 119 EMTs, and when they had short work experience and were dissatisfied with their job, the degree of fatigue was higher. Moreover, there was a significant correlation between emotional labor, job stress, and fatigue of the 119 EMTs. Conclusion: To reduce emotional labor, job stress, and fatigue of 119 EMTs, appropriate interventions for each factor and institutional improvements are required.

Archaebacteria Sulfolobus acidocaldarius contains the highly thermophilic cytochrome P450 enzyme (CYP119). CYP119 possesses stable enzymatic activity at up to $85^{\circ}C$. However, this enzyme is still considered as an orphan P450 without known physiological function with endogenous or xenobiotic substrates. We characterized the regioselectivity of lauric acid by CYP119 using the auxiliary redox partner proteins putidaredoxin (Pd) and putidaredoxin reductase (PdR). Purified CYP119 protein showed a tight binding affinity to lauric acid ($K_d=1.1{\pm}0.1{\mu}M$) and dominantly hydroxylated (${\omega}-1$) position of lauric acid. We determined the steady-state kinetic parameters; $k_{cat}$ was 10.8 $min^{-1}$ and $K_m$, was 12 ${\mu}M$. The increased ratio to $\omega$-hydroxylated production of lauric acid catalyzed by CYP119 was observed with increase in the reaction temperature. These studies suggested that the regioselectivity of CYP119 provide the critical clue for the physiological enzyme function in this thermophilic archaebacteria. In addition, regioselectivity control of CYP119 without altering its thermostability can lead to the development of novel CYP119-based catalysts through protein engineering.

Purpose: This study aims to compare 119 emergency medical services (EMS) in South Korea and Japan to provide essential data for EMS improvement in South Korea. Methods: Recent data and regulations on firefighting and EMS in South Korea and Japan were analyzed and compared. Results: South Korea follows a centralized approach to EMS, whereas Japan operates with autonomous bodies that establish their own criteria. Japan considers more regional variables than South Korea. In South Korea, there are shortages in fire station deployment among the 119 emergency medical resources in certain regions, leading to significant regional disparities. South Korea has a larger population served by its 119 emergency medical resources with a higher workload and dispatch numbers than Japan. The percentage of non-transported patients among the total number of dispatches was higher in South Korea. Conclusion: Increasing the number of medical professionals and ambulances per population to the level of Japan to reflect local conditions and include various underlying variables such as daytime population, aging, and emergency dispatch conditions in the deployment of 119 emergency resources, and to reduce the deployment gap between regions, will contribute to improving the performance of the South Korea EMS system.

The present study investigated the effects of work satisfaction on quality of life for 119 paramedics, the Korean equivalent of 911 paramedics. Data collection began in July 2017 and lasted for six months. Data was collected from 410 119 paramedics of the J province and the G metropolitan area who consented to study participation. The results showed that the higher the job satisfaction of the participants, the higher the quality of life (r = 0.508, p = 0.008). The factors affecting the quality of life were leisure activity, subjective health, and job satisfaction. For 119 paramedics to improve their quality of life, they need to relieve work stress and fatigue through leisure activities, and recover and maintain their health through sufficient rest. Moreover, returning to work in a healthy state likely leads to increased job satisfaction, and the quality of life will increase accordingly. Therefore, 119 paramedics should be permitted to have plenty of leisure time outside their work hours and should be able to maintain health through periodic health checks.

Purpose: This study aims to investigate the degree of burnout of 119 rescuers, to determine factors influencing their burnout, and to provide basic data for development of intervention programs to prevent the burnout. Methods: Subjects of this study were all 119 rescuers working at fire stations located in Busan and Gyeongnam. The data were collected from May 1, 2010 to June 30, 2010. The collected data were analyzed with SPSS/WIN 17.0. Results: When the difference in the degree of burnout by general characteristics was investigated, the means of burnout were significantly different depending on age, period of service, position, license, annual salary, desire to work continuously and types of working hours. Job stress, job satisfaction, social support, self efficacy and self esteem showed a statistically significant correlation with burnout. The degree of burnout became higher with more job stress and lower job satisfaction, social support, self efficacy and self esteem. As a significant factor affecting the degree of burnout of 119 rescuers, job stress showed 47.3% of explanatory power. The explanatory power of all of job stress, job satisfaction, self efficacy, types of working hours, annual salary and license was 62% and the power of job stress was the highest. Conclusion: From these results, job stress, job satisfaction and self-efficacy were found to be factors affecting the burnout of 119 rescuers. Therefore, intervention programs to reduce job stress and to improve job satisfaction, social support, self efficacy and self esteem should be developed to lower the degree of burnout of 119 rescuers. In addition, further researches to analyze works of 119 rescuers and legal and institutional strategies to improve their treatment are necessary and supplementary training in various practices by different circumstances based on standardized protocols should be conducted.

Purpose: This study intended to improve quality of prehospital emergency care for trauma patients by figuring out its current situations and problems based on run-sheets and questionnaires of 119 emergency medical technicians (EMTs). Methods: This study conducted a research of 425 trauma patients transferred to the 3rd hospital in G-city by 119 ambulances from July 1, 2008 to June 30, 2009. We aslo utilized 114 copies with questionnaires of 119 EMTs working in J-province. The data were analyzed with SPSS 18.0. Results: There were 425 trauma patients including 272 men and 137 patients with traffic accident. When it comes to types of 119 EMTs who delivered cares to patients, there were 206 (48.5%) advanced EMTs, 101 (23.8%) basic EMTs, 50 (11.8%) nurses and 43 (10.2%) rescue education receivers. The most frequent measured vital sign was pulse rate (54.1%). Regarding assessment of systolic blood pressure, pulse rate and respiration rate, there were some significant differences in accordance with type of 119 EMTs. Among the 317 patients evaluated 'emergency' in field, 137 patients returned to their home. Prehospital emergency cares accounted for 861, around 2.0 treatments per a patient. In view of questionnaire, the 74.6% of 119 EMTs hoped supplement of man power for proper prehospital care to trauma patients. Conclusion: This study suggested that it is necessary to develop detailed guidelines for trauma patients so as to improve quality of trauma patient evaluation and prehospital care. Furthermore, improvement of emergency care systems will reduce mortality of trauma patients and lead to their good outcome.
