The purpose of this study is to examine the effect of supportive nursing intervention on patient's response of anxiety in emergency room as the suspected experimental research sequentially designed for the unequal control group. This study collected the data from 100 patients including 50 patients of experimental group and 50 patients of control group in emergency room of the only one university hospital from July 12. to September 30, 1999. This study used questionnaires that Kim, Jung Taek and Shin. Dong Kyun revised the measurement of STAI(State-Trait Anxiety Inventory) of Spielberger(1972) to measure their anxiety with using physical. spiritual. and informative support of the supportive nursing intervention, and measured blood pressure. pulse and respiration by physiological response of anxiety. After then. this study analyzed the frequency and percentage by using SPSS 7.5 program, $x^2-test$, t-test and ANCOVA. The results are as follows: First hypothesis : the point of STAI of experimental group who received the supportive nursing intervention during emergency room staying will be lower than that of control group without the supportive nursing intervention(F=22.943, p=.000). Second hypothesis : the sistolic blood pressure of experimental group who received the supportive nursing intervention during emergency room staying will be lower than that of control group without the supportive nursing intervention(F=42.603. p=.000). Third hypothesis. the diastolic blood pressure of experimental group who received the supportive nursing intervention during emergency room staying will be lower than that of control group without the supportive nursing intervention(F= 18.482, p=.000). Fourth hypothesis: the pulse of experimental group who received the supportive nursing intervention during emergency room staying will be lower than that of control group without the supportive nursing intervention. Fifth hypothesis : The respiration of experimental group who received the supportive nursing intervention during emergency room staying will be lower than that of control group without the supportive nursing intervention. In the above-mentioned result. the supportive nursing intervention was considered to be useful intervention that raised the effect on patient's response of anxiety during emergency room staying.

The Korea retrospective dosimetry (KREDOS)-electron paramagnetic resonance (EPR) group undertook an intercomparison investigation utilizing hydroxyapatite. This analysis involved four institutions: the Korea Institute of Radiological and Medical Sciences, Dongnam Institute of Radiological and Medical Sciences, Korean Association for Radiation Application, and Radiation Health Institute of Korea Hydro & Nuclear Power. Following the irradiation of the hydroxyapatite sample, the recorded build-up was analyzed. To validate the reliability of the EPR dosimetry findings and enhance its operational performance, a hydroxyapatite dose-response curve was plotted and dosimetry was performed for a blind sample. The proficiency of each laboratory was assessed by employing an interlaboratory comparison methodology. This involved a comparative analysis of the measurement results by calculating the relative bias, z-score, and En value. The results submitted by the participating laboratories demonstrated satisfactory ratings for doses of 1.006, 3.999, and 6.993 Gy. Following the second intercomparison, efforts to optimize their hydroxyapatite-EPR dosimetry systems are underway in the participating laboratories. The current assessment of hydroxyapatite dose yielded the foundational data required to establish the parameters of dental dosimetry. In future, the third intercomparison experiment will be conducted for exploring other materials.

This study was attempted to provide fundamental data in a disaster response education program by comparing the differences between students of the paramedic and nursing in ego-resilience, disaster-experience and core competencies of disaster response. The data is collected from March 2 to April 2, 2019, on a total of 358 students (196 paramedic students and 162 nursing students) based in Jeolla Province. The structured questionnaire were used as research tools and the collected data were analyzed by using the SPSS program as frequency, percentage, t-test, ANOVA and Pearson's correlation coefficient. The average score of total ego-resilience among the subjects was 86.97 out of 125 points. The number of paramedic students who experienced or witnessed the disaster situation in person was 11.2%, and the number of nursing students was 11.7%. The core competence of disaster response was 3.21% in paramedic students and 3.16% in nursing students. The ego-resilience of the paramedic and nursing students according to their general characteristics is statistically significant differences (t=2.797, p<.005) and the paramedic students has an average score of 3.52 points, which is higher than the nursing students (3.42 points). General characteristics and experience in disasters are statistically significant differences (t=2.797, p<.005), paramedic students had more disaster experiences (3.11 points) than nursing students (2.67 points). It indicated the static correlation relationship between ego-resilience, disaster experience and core competences of disaster response (p<.000). Through this study, the paramedic students were found to be more ego-resilience, more disaster experience and more critical capacity for disaster treatment than nursing students.

Purpose: There has been an increase in the number of prehospital cardiac arrests due to the increasing number of cardiovascular diseases and the increase in the average age of the population. We performed this study to identify the proper resuscitation technique and AED to be used to increase the survival rate in prehospital cardiac arrests. Methods: This studied 159 victims with prehospital cardiac arrests(VF or VT rhythm) by EMT's Reports from January to August, 2005. Results: 108 of 159 victims(67.9%) were shocked by AED. Eighty of 159 victims(50.9%) were recorded with AED shock in prehospital cardiac arrests. A number of shocks is averaged 2.19; 46.2% of one-shock and 86.1% of 1-3 shock. EMS first-tier response interval from time of dispatch to scene arrival was 5.88 minutes, from scene arrival to scene start was 7.36 minutes, from scene start to hospital admission was 9.91 minutes and from scene arrival to AED shock was 6.84 minutes. EMT provided advanced care to prehospital cardiac arrests: 97.5% in CPR, 10.1% in advanced airway management, 67.9% in AED shock. Conclusion: With the increase in cardiovascular disease and old age, the number of prehospital cardiac arrests has risen gradually. However, there were lack of CPR by bystander, defibrillation and advanced cardiac life support(ACLS) in prehospital stage. To improve the adequacy of basic life support and to increase the performance of ACLS, especially AED, we must create challenges to develop new protocols in prehospital care.

Background: In cardiac arrest, the survival rate increases with the provision of bystander cardiopulmonary resuscitation (CPR), of which the initial response and treatment are critical. Telephone CPR is among the effective methods that might increase the provision of bystander CPR. This study aimed to describe and examine the improvement of neurological outcomes in individuals with out-of-hospital acute cardiac arrest by implementing the nationwide, standardized telephone CPR program. Methods: Data from the emergency medical service-based cardiac arrest registry that were collected between 2009 and 2014 were used. The effectiveness of the intervention in the interrupted time-series study was determined via a segmented regression analysis, which showed the risk ratio and risk difference in good neurological outcomes before and after the intervention. Results: Of 164,221 patients, 148,403 were analyzed. However, patients with unknown sex and limited data on treatment outcomes were excluded. Approximately 64.3% patients were men, with an average age of 63.7 years. The number of bystander CPR increased by 3.3 times (95% confidence interval [CI], 3.1-3.5) after the intervention, whereas the rate of good neurological outcomes increased by 2.6 times (95% CI, 2.3-2.9 [1.6%]; 1.4-1.7). The excess number was identified based on the differences between the observed and predicted trends. In total, 2,127 cases of out-of-hospital cardiac arrest (OHCA) after the intervention period received additional bystander CPR, and 339 cases of OHCA had good neurological outcomes. Conclusion: The nationwide implementation of the standardized telephone CPR program increased the number of bystander CPR and improved good neurological outcomes.

Purpose: This study measured return of spontaneous circulation (ROSC) in relation to dispatch distance in patients with out-of-hospital cardiac arrest. Methods: Of 2,347 out-of-hospital cardiac arrest patients transported by emergency medical technicians in J Province between January 1 and December 31, 2015, those under age 18, those with reserved resuscitation, and those with traumatic cardiac arrest, leaving 855 patients in the study sample. ROSC was compared between those with dispatch distance ${\leq}4km$ (short dispatch distance, 465 patients) and those with dispatch distance >4 km (long dispatch distance, 390 patients). Results: The mean was 2.17 km in the short dispatch group and 9.87 km in the long dispatch group (p=.000). Mean distance from was 6.49 km and 13.39 km in the two groups, respectively (p=.000). ROSC differed significantly between the short and long dispatch distance groups (7.1% for short dispatch distance, 3.6% for long dispatch distance, p=.025). The length of time from to cardiopulmonary resuscitation also differed significantly between the short and long dispatch distance groups (8.77 minutes and 14.63 minutes, respectively, p=.000). Conclusion: ROSC was lower in areas of long dispatch distance compared to those of short dispatch distance. We expect this was most likely due to differences in response time by age and dispatch distance to the scene of cardiac arrest. However, no significant differences were found between the groups in the factors affecting ROSC.

The purpose of this study was to investigate 119 rescue party's violence experiences and to analyze their responses of violence experiences based on the pre-hospital emergency medical field. Data were collected from the self-administered survey of 226 rescue party in Jeollabuk-do area in Korea from January 1 through March 2, 2009. The data were analyzed by descriptive statistics and logistic regression analysis using SPSS Win 12.0. The results were as follows: first, all of 119 rescue unit in the pre-hospital emergency medical field reported that they got violence experiences more than once a week, and 62% of rescue team were exposed to physical violence. Patient's factors that caused violence were drug abuse or alcohol(56.2%), on the other hand rescue party's factors were shortage of human resources. Second, 42% of the respondents replied that they did not have any educational experiences for prevention and coping methods about violence within 5 years. 77.4% of those surveyed indicated that they wanted to receive specific educations which can prevent and cope with violence. Third, the mean value of total violent response scores was 2.53, and emotional response score was 3.2, social response score was 2.22, and physical response score was 2.17. Fourth, violent response score related to general characteristics proposed that physical(t=-2.08, p=o.38), emotional(t=-7.13, p=.006), and total responses(t=-4.764, p=.000) were statistically significant. And emotional(t=4.257, p=.000) and total responses(t=8.1330, p=.000) related to age were also statistically significant. Finally, among current tenure qualification scores, social response(t=9.987, p=.012) and total score(t=8.130, p=.000) were statistically significant. Between fire departments, violent response score suggested that physical(t=9.987, p=.000), emotional(t=2.433, p=.012), social(t=6.738, p=.000), and total score(t=5.943, p=.000) were statistically significant.

An Emergency Medical Technician (EMT) is a well-trained emergency responder to provide emergency medical services to the critically ill and injured patient. In various situations, EMT may destroy potential physical evidences associated with the crime scene or determination of real cause of death. This study was aimed to evaluate the educational need of forensic medicine in Korean EMT. Questionnaires were administered to 592 EMTs during March 2007. The response rate was 60.3%(357 EMTs). In questionnaires there were 13 questions regarding the general characteristics, 16 questions about roles of EMTs related with forensic circumstances, 9 questions about the education related to forensic medicine. Questionnaires rated on a 4-point Likert scale or 5-point Likert scale. Most of 119 rescue EMTs had experienced with situations related to crime or unexpected sudden death. EMTs had arrived to the scenes earlier than police and complained of some difficulties related with deficit of forensic knowledge. EMTs wanted to receive continuous educations about forensic medicine. In order to reduce dissatisfaction with EMTs roles and to improve crime scene preservations, Emergency Medical Services policies should provide regular educational curriculum by forensic pathologists and promote legal responsibilities for 119 rescue EMTs.

Poisonings caused by 'mad honey' are known to occur in response to grayanotoxins, which bind to sodium channels in the cell membrane, increasing membrane sodium permeability and preventing inactivation. Mild symptoms of mad honey intoxication are dizziness, weakness, hypersalivation, nausea, vomiting, and paresthesia. Severe intoxication, however, leads to serious cardiac manifestations such as atrioventricular block, dose-dependent hypotension, bradycardia, and respiratory depression. Atropine and vasoactive drugs improve symptoms of both bradycardia and respiratory rate depression. We report an unusual case of saliva-type hyperamylasemia in a mad honey poisoning patient who developed clinically significant bradycardia. She recovered fully within 3 days following atropine administration and medical treatment.

Many first aiders suffer from the stress of working in uncertain disaster sites. The stress of responding to disasters leads to an increase in post-traumatic stress disorder (PTSD) and a decrease in psychological well-being. It also has many negative effects on the meaning in life for first aiders. Reduced meaning in life will result in many societal opportunity costs due to decreased health and work engagement. To address this issue, this study conducted a survey to analyze the level of meaning in life of first aiders. The results indicated that the overall level of meaning in life of first aiders is very low. This issue needs to be addressed sooner rather than later, given the increasing trend of emergency response. Based on the results of the study, measures were proposed to reduce PTSD and psychological stability by restoring the meaningfulness of first aiders' lives.
