Purpose: To identify work stress and job satisfaction of the emergency medical technician (EMT) and to contribute to the improvement of emergency care under the current emergency medical law. Methods: The data were collected by questionnaire from the total 849 EMTs (635 National emergency management agency (119) workers and 214 hospital workers) throughout the whole country from January 5, to March 5, 2012. Each level of indicator calculated under 100-point-scale was compared by t-test and ANOVA. Factors affecting stress and satisfaction were analyzed by Multiple Linear Regression Analysis (${\alpha}$=.05). Results: Mean level of job stress was markedly higher among 119 workers (76.9) than those in the hospital (56.6) (p<.001). Mean level of job satisfaction was higher among 119 workers (63.2) than those in the hospital (60.2) (p<.001). Conclusion: To diminish work stress and to increase job satisfaction, efforts to support the pride and to improve working condition considering the situations of the agency and to offer more education chance to keep and strengthen the specialty are needed.

The major objective of this research is to evaluate performance of improved intersections for response time to emergency vehicle preemption. Smart technologies have been introduced to civil infrastructure systems for resilient communities. The technologies need to evaluate their effectiveness and feasibility to confirm their introduction. This research focuses on the performance of emergency vehicle preemption, represented by response time, when smart intersections are introduced in a community. The response time is determined by not only intersections but also a number of factors such as traffic, distance, road conditions, and incident types. However, the evaluation of emergency response has often ignored factors related to emergency vehicle routes. In this respect, this research synthetically analyzes geospatial and incident data using each route of emergency vehicle and conducts before-and-after evaluations. The changes in performance are analyzed by the impact of smart intersections on response time through Bayesian regression models. The result provides measures of the project's performance. This study will contribute to the body of knowledge on modeling the impacts of technology application and integrating heterogeneous data sets. It will provide a way to confirm and prove the effectiveness of introducing smart technologies to our communities.

The rapid development and widespread application of Internet has provided a platform for people to participate and discuss social hotspot events. In the meantime, social events may be spread throughout the Internet more quickly and widely than they did ever before, and possibly lead to serious social problems due to opinion violence or seditious rumour. This paper analyzed the Internet spread of social events, and presented a five-stage model to describe the evolution process of that spread. Furthermore, the improved IBF algorithm was applied to extract a pruned connected graph aiming to find the key nodes and the shortest spread path for the control of that spread. After analyzing the different factors that may cause the netizens' attention, this paper concluded BBS type, the visit quantity and the opinion leader are key factors which affect the Internet spread. Based on those researches, a life-cycle emergency management methodology and the related strategies were proposed for the achievement of healthy spreading environment on Internet.

Background: This study was conducted to compare the effectiveness of low-dose ketamine versus ketorolac in pain control in patients with acute renal colic presenting to the emergency department (ED). Methods: This is a double-blind randomized clinical trial. The initial pain severity was assessed using the numerical rating scale (NRS). Then, ketamine or ketorolac was administered intravenously at a dose of 0.6 mg/kg and 30 mg respectively. The pain severity and adverse drug reactions were recorded 5, 15, 30, 60, and 120 min thereafter. Results: The data of 62 subjects in the ketamine group and 64 patients in the ketorolac group were analyzed. The mean age of the patients was $34.2{\pm}9.9$ and $37.9{\pm}10.6\;years$ in the ketamine and ketorolac group, respectively. There was no significant difference in the mean NRS scores at each time point, except for the 5 min, between the two groups. Despite a marked decrease in pain severity in the ketamine group from drug administration at the 5 min, a slight increase in pain was observed from the 5 min to the 15 min. The rate of adverse drug reactions, including dizziness (P = 0.001), agitation (P = 0.002), increased systolic blood pressure (> 140 mmHg), and diastolic blood pressure (> 90 mmHg) was higher in the ketamine group. Conclusions: Low dose ketamine is as effective as ketorolac in pain management in patients with renal colic presenting to the ED. However, it is associated with a higher rate of adverse drug reactions.

Purpose: This study investigated the health status and health management program of 119 emergency medical technicians (EMTs). Methods: A self-reported questionnaire was completed by 794 EMTs in two cities from November 15 to December 20, 2016. The questionnaire collected the general characteristics of the subjects (10 items) and health-related information from 119 EMTs (14 items). Data were analyzed by using SPSS 23.0. Results: The mean value for the general health status of the 119 EMTs was 2.68. The general health status was lower for female 119 EMTs, older 119 EMTs, and married 119 EMTs; it was higher for 119 EMTs with more than 5 years of experience and for 119 EMTs with diseases. The mean value for work-related fatigue of the 119 EMTs was 3.26. This value was higher for female 119 EMTs (p<.05). 119 EMTs with more than 2 years of experience, and 119 EMTs with diseases (p<.01). The correlation between health program participation and general health status was significantly positive (r=.271), whereas the correlation between health program participation and work-related fatigue was significantly negative (r=-.375). The correlation between health program participation and program satisfaction was significantly positive (r=-.770). Conclusion: It is important to develop health management program for 119 EMTs and to offer them at all times. Moreover, the health status of 119 EMTs can be increased through improvements to working environments.

Purpose. Based on the comparison and analysis with those of United States, the aim of this research is to find the problems in current management, operation and future directions of emergency medical service (EMS) fund in S. Korea and to provide basic resources and appropriate measures to make a right decision in policies for EMS fund. Methods. Data from Ministry of Health and Welfare and other various sources during 1995 to 2012 were collected and analyzed. Results. From our analyses, several problems are identified in EMS fund operation. In brief, problems discerned are as follows. First, whereas the purpose and direction of EMS fund operations in United States are highlighted and focused on pre-hospital EMS system and associated infrastructures which need to be constructed, those of S. Korea are emphasized mainly on the in-hospital EMS system so far. Second, on the contrary to the fact that the EMS funds in United States are tuned to pre-hospital EMS system to provide prompt and efficient emergency care at the emergency scene of pre-hospital stage and to achieve the development, design, planning and demonstration projects for pre-hospital EMS systems, up to date, our investment of EMS funds demonstrated an excess biased inclination toward the construction of in-hospital EMS system, which is far from the realization of constructive and vital pre-hospital infrastructures. Third, while emergency medical technician is important and principal body in the management of emergency medical funds in United States, so far, no EMS funds in S. Korea existed for EMTs including the job condition, improved treatment and working environment for them. Conclusion. In conclusion, we strongly suggest that the problems pointed out must be revised and corrected. Current usage of EMS fund needs to be redirected predominatly to pre-hospital EMS system. Otherwise, unless current management and investment of emergency medical funds in S. Korea are applied and used for the vital necessities and demands of EMTs, public EMS units and private EMS units as well as related units in pre-hospital EMS system as in the cases of United States, in our consideration, they must be suspended or abolished.

Purpose: With the increasing numbers of foreign residents in Korea, the need for an emergency medical care system for foreign patients seems to be growing. Sometimes, a foreigner admitted to an emergency room is not treated sufficiently due to the absence of insurance, facility in the Korean language, and a guardian. The management of a foreigner with trauma in the ER is difficult due to various problems such as social and economic status. The purpose of this study was to investigate the current management status of foreigners with penetrating wounds in the emergency room. Methods: This study is an analysis of 580 patients that were diagnosed with penetrating wounds in one teaching Hospital from Jan. 1, 2008 to Dec. 31, 2008. We analyzed results according to nationality, alcohol ingestion, intentional or accidental trauma, trauma mechanism, injury severity, management time in the ER, and outcome in the ER. Results: Of the total 580 patients, 486 patients (83.8%) were native Koreans and 94 patients (16.2%) were foreigners. According to the Revised Trauma Score, the average score of native Korean patients was 7.808, and the average score of foreign patients was 7.638. Of native Korean patients, 22.6% had knife wounds while 38.3% of foreign patients did. Of native Korean patients, 17.3% experienced intentional trauma while 33.0% of the foreign patients did. Of native Korean patients, 22.5% had ingested alcohol while 49.4% of the foreigners had. Of native Korean patients, 10.5% were admitted while 7.6% of the foreign patients were. Of native Korean patients, 14.2% were discharged against medical advice (DAMA), while 18.5% of foreign patients were. Of native Korean patients, 1.2% ran away while 8.7% of the foreign patients did. Conclusion: Stabbing was the most common cause of penetrating wounds in foreigner patients in this study. Intentional trauma was more common in foreigners with penetrating wounds than in native Koreans. The severity was higher in foreigners with penetrating wounds than it was in native Koreans, and patients who ran away or were discharged against medical advice were more commonly foreigners with penetrating wounds. Social insurance or policy is needed for the management of foreigners with penetrating wounds.
