Purpose: Effective time management, as well as life-saving care, are important in maximizing the prognosis of patients who have sustained major traumas. This study evaluated the appropriateness of emergency medical system (EMS) provider's essential care and how this care impacted on-scene time in patients with major traumas. Methods: This retrospective observational study analyzed the EMS major trauma documents, classified according to the physiological criteria (Glasgow coma scale <14, systolic blood pressure <90mmHg, Respiration rate <10 or >29) in Daejeon, from January, 2015 to December, 2018. Results: Of the 707 major trauma cases, the mean on-scene time was 7.75±4.64 minutes. According to EMS guidelines, essential care accuracy was 67.5% for basic airway, 36.4% for advanced airway, 91.2% for cervical collar, 81.5% for supplemental oxygen, 47.0% for positive pressure ventilation, 19.9% for intravenous access and fluid administration, and 96.0% for external hemorrhage control. Factors affecting on-scene time were positive pressure ventilation (p<.004), and intravenous access and fluid administration (p<.002). Conclusion: Adherence to guidelines was low during advanced airway procedures, positive pressure ventilation, intravenous access, and fluid administration. In addition, the on-scene time was prolonged when the practitioner provided positive pressure ventilation, intravenous access, and fluid administration; however, these durations did not exceed the recommended 10 minutes.

We propose ID-exchange protocol for Connectionless Location-Awareness Service (CLAS) to locate mobile nodes in indoor sensor network. When adapting location-awareness service to sensor network, the target system must be designed in accordance with various metrics which reflect the system requirement. We especially consider sustainability of the existing service which has been provided for its original purpose, such as environmental monitoring. The detailed meaning of sustainability here is that, even if location-awareness service is newly added to the existing service, the system must be assured to retain a stable network condition, and to deal with newly caused traffic properly. The CLAS ID-exchange protocol is especially designed for fixture and mobile nodes communication to achieve these properties. The protocol operates on 802.15.4 MAC layer to make mobile node work independently of the procedure to build routing table of fixture node, so a stable routing condition can be achieved even if there are many mobile nodes. Moreover, the dedicated frequency channel is assigned only for this protocol, so that traffic caused by location-awareness service can be distributed to another channel. A real system adapting the protocol was implemented to monitor fire and authorities' positions. We verified the overhead and elapsed time for location-awareness. The result shows the proposed protocol has a high performance in detecting speed, traffic distribution, and stability of overall network.

Purpose: This descriptive study examined awareness of and ethical attitudes associated with Do Not Resuscitate (DNR) orders in 119 emergency medical technicians (EMTs). Method: In total, 255 paramedics and basic EMTs completed questionnaires between March and May, 2013. Data were analyzed using the SPSS WIN 18.0 program. Results: A chi-square analysis revealed significantly different responses given by paramedics and basic EMTs: Paramedics gave "the reason in which DNR is not necessary", as being "due to unclear DNR decision time" whereas basic EMTs answered that this was "due to a legal problem" ($x^2$ = 12.680, p < .05). Paramedics disagreed with the statement, "It is natural for medical teams to have less interest in patients with DNT orders", whereas basic EMTs agreed with the statement ($x^2$ = 6.666, p < .05). Conclusion: A unified manual on attitude toward DNR orders, taking account of social and culture factors, needs to be developed. This research provides a base line for future research.
