Purpose : The purpose of this study is to get basal user guidelines of safer bag-valve-mask application on patient with normal pulmonary patho-physiologic condition. Methods : This study was accomplished by pre-qualified 25 EMS junior grade students. Participants were instructed randomly compress bag to one-third, half and total and also with differesnt compression speed. Resultant tidal volumes and mean airway pressures obtained in RespiTrainer were analysed in relation to the each compression depth and rate. Results : Demographic difference does not affect tidal volume with any compression depth and rate change. Increasing compression depth is correlated with tidal volume increasement at any compression rate and also with mean airway pressure. If the compression depth is same, compression rate change did not affect significantly the resultant tidal volume or mean airway pressure. Conclusion : Hand size, Experience, BMI dose not affect tidal volume. Compress the 1600 ml bag half to total amount is safe way to offer sufficient tidal volume without risky high airway pressure delivery to patient airway who with normal lung patho-physiologic condition.

This paper proposes and implements a LoRa-based emergency exit guide system which can direct the optimal refuge path accounting for the real state of the fires. Each 4-way emergency exit guide sign presents a right direction through one of four LED signs toward the possible exit dynamically calculated by the shortest path algorithm. We constructed a simulation environment with 8 spots of the emergency exit guide signs and 2 exits, which can simulate variant cases of fire accidents, and showed that the proposed algorithm can presents the right guidance for each emergency exit guide sign. We also evaluated the performances of LoRa-based wireless communications using a self developed communication module in the various indoor and outdoor environments. The proposed system can be applied to small and medium sized buildings as well as larger ones in terms of cost efficiency, in which there's no needs to invest for the complex equipments except only sensors and emergency exit guide signs.

Objective : The objective of this study was to survey the job satisfaction and turnover intention of 119 emergency medical technicians who are fire fighters and, at the same time, provide emergency patients with first aid, to examine the correlation between their job satisfaction and turnover intention, and to provide basic materials for the human resource management of 119 emergency medical technicians. Method : The survey was conducted with 152 119 emergency medical technicians working at fire stations in an area of Gyeonggi-do during the period from July 15 to September 14, 2009. Job satisfaction was measured with a tool developed by Kim Sun-sim and Kwon Hye-ran (2002) based on the Index of Work Satisfaction, and turnover intention with the tool developed by Becker (2002) and translated and used by Cho Yeong-sook (2002). The questionnaire was composed of 11 questions on general characteristics, 35 on job satisfaction, and 4 on turnover intention, so a total of 50 questions. The reliability of the questionnaire was Cronbach's ${\alpha}=0.922$ for job satisfaction and Cronbach's ${\alpha}=0.854$ for turnover intention. Using SPSS 14.0, we obtained frequencies, percentages, means, and standard deviations, and performed independent two-sample t-test, one-way ANOVA, and Pearson correlation analysis, and Cronbach's ${\alpha}$. Results : 1) The mean score of the 119 emergency medical technicians' job satisfaction was 2.71, and that of their turnover intention was 2.64. By area of job satisfaction, the mean score was 3.44 for the area of job itself, 2.92 for the interaction area, 2.67 for the organizational demand area, 2.64 for the autonomy area, 2.14 for the wage area, and 1.91 for the working condition area, showing that emergency medical technicians were generally satisfied with their job itself but not with their working condition. 2) As to difference according to the 119 emergency medical technicians' general characteristics, statistically significant difference was observed in job satisfaction according to license type (F = 4.729, p < .010), and in turnover intention according to position (F = 3.768, p < .025). 3) The 119 emergency medical technicians' job satisfaction and turnover intention was in a negative correlation with each other (r = -.44, p < .000) in general, and by the sub-areas of job satisfaction, the correlation with turnover intention was high in order of the autonomy area (r = -.42, p = .000), interaction area (r = -.42, p = .000), job itself (r = -.35, p < .000), organizational demand area (r = -.30, p = .000), wage area (r = -.23, p = .000), and working condition area (r = -.21, p = .008). Conclusion : The 119 emergency medical technicians' job satisfaction showed a negative correlation with their turnover intention. This suggests that turnover intention can be reduced by improving job satisfaction. Furthermore, 119 emergency medical technicians' job satisfaction was high with the job itself, showing their high pride in their job, but was low with working condition and wage. Thus, it is necessary to enhance their job satisfaction by improving the 24-hour work system through supplementing manpower, compensating for overtime works, adjusting work hours per week, etc. These results are expected to be useful in making human resource management plans to lower turnover intention by enhancing 119 emergency medical technicians' job satisfaction.

In the past several years the popularity of the motor cycle has produced an increasing incidence of the injuries to the larynx and trachea. Most of all on accidents come to death and survivors to the hospital are rare. Early diagnosis and to keep air way are necessary to initiate proper treatment in injury of upper air way. Meticulous apposition of mucous membrane and reconstitution of laryngeal skeleton are important. We experienced a rare case of 26 year old men with cricothyroidal transection after trauma. On Oct. 17, 1985, the patient struck his neck on baggage frame of truck when dropping from his motor cycle on sudden stop. Emergency tracheal intubation on distal segment of trachea was accomplished by otolaryngologist in a local clinic. He was transferred to our hospital. Exploration 2 hours later revealed complete separation of cricoid cartilage from thyroid cartilage. The recurrent laryngeal nerve could not be identified. Anastomosis of thyroid and cricoid was accomplished and Portex endotracheal tube was inserted as splint for 10 days. No stenosis developed. The air way appeared adequate for moderate physical activity though paramedian fixation of vocal cord paralysis. Postoperative follow-up course has been good after he discharged on POD 14 days.

Purpose: This study was done to identify relationships among post-traumatic stress (PTS), job stress and turnover intention in emergency department (ED) nurses. Methods: Participants were 250 ED nurses who had worked for one month or longer in the ED one of three university hospitals or seven general hospitals in Daegu City or Gyeong Buk Province in Korea. Structured questionnaires were used to measure PTS, job stress, and turnover intention of participants. Data were analyzed using descriptive statistics, one-way ANOVA, path analysis, and stepwise multiple regression with the SPSS program. Results: There were significant relationships between PTS, job stress and turnover intention. PTS influenced turnover intention directly and was indirectly mediated by job stress. The experience of traumatic events influenced PTS, job stress, and turnover intention. Indirect experience of traumatic events in the ED was an important predictor, explaining 20.1% of PTS in high-risk post-traumatic participants. Conclusion: PTS can be an important factor for job stress and turnover intention. The direct and indirect experience of traumatic events can influence PTS, job stress, and turnover intention in ED nurses. Based on these results, strategies for managing PTS and relating job stress are recommended to reduce turnover intention in ED nurses.
