Purpose: This study attempts to provide information for developing a preceptorship education program by analyzing the recognition and acceptance of the introduction of paramedic preceptorship in the clinical practice of paramedic students in Korea. Methods: Data were collected from 120 paramedics from December 26, 2013, to February 20, 2014. A questionnaire consisting 33 questions was administered, and the collected data were analyzed using SPSS version 21.0. Results: The overall responses were positive, and the subjects were very interested in the introduction of paramedic preceptorship in paramedic education and clinical practice settings. The mean score for preceptorship acceptance was 3.97 on a 5-point Likert scale. In terms of recognition, 59.0% of the 78 subjects were able to explain preceptorship. In terms of acceptance, 85.8% of the subjects agreed with preceptorship and 81.7% considered an effective training method. Conclusion: Most of the subjects agreed that preceptorship is very important for the education of paramedic students. The preceptorship education program development will be the basis of clinical practice.

Purpose: The purpose of this study was to investigate emergency room nurses' recognition of patient safety culture and their performance of safety management activity. Methods: Data were collected from July 1 to August 31, 2012 on 292 emergency room nurses working at 25 general hospitals located in B city in G province. The Hospital Survey on Patient Safety Culture was used to measure patient safety culture, and an 82-item questionnaire was developed to measure safety management activity. Results: the performance of safety management activity were significantly associated with the total career years, whether the nurses had undergone safety training, and whether the nurses has been working in the regional emergency care facility. Of 6 subcategories of the patient safety culture, the perception of a directly commanding senior/manager, frequency of accident reports, and hospital environment were associated with the performance of safety management activity. Conclusion: For improving performance of safety management activity among emergency room nurses, it is necessary to develop an educational program of safety management activity by their level of performance.

일반적으로 어떤 순간에 발생할지 모르는 응급 상황을 CCTV의 영상 정보만으로 상황을 항상 모니터링하기에는 인력과 비용의문제점이 발생되고 있다. 본 논문에서는 응급상황을 동적으로 보여주는 CCTV환경에서 감지하기 위해 음성인식 기술을 도입하여 문제점을 해결하고자 한다. 이를 위해 본 논문에서는 HMM(Hidden Markov Model) 기반 음성인식을 이용하여, 상황판단의 선택 여부로 고려하였으며, CCTV 환경의 기본적인 잡음 환경은 Wiener 필터를 이용하여 효과적으로 제거하고자 하며, 향후 응급 상황만을 효과적으로 CCTV 관리자에게 제공을 하여 상황인지 하고자 한다.

본 논문은 차량이 사고가 발생하였을 때, 사고 차량이 가까이에 있는 주위 차량에 긴급메시지를 전파하여, 다른 차량의 운전자들이 사고지점을 인지하고 회피할 수 있도록 효과적이고 빠른 브로드캐스트 기법에 관하여 기술하였다. 본 논문에서는 GPS(Global Position System)가 장착된 도심환경의 차량 네트워크에서 긴급 메시지를 빠르게 전파하는 방법을 제안한다. 전송 차량은 연속적이고 효과적인 메시지 전파를 위해 가장 멀리 있는 차량을 다음 릴레이 차량으로 미리 선정하고 전파를 하는 기법을 제안한다. 그리고 RSU(Road Side Unit)의 도움 없이 교차로를 인식할 수 있는 알고리즘을 제안하며, 끊어진 네트워크 상황에 대처하기 위해 헬로 메시지를 이용한 SCF(Store-Carry-Forward) 기법을 제안한다.

Fitz-Hugh-Curtis syndrome (FHCS) is characterized by inflammation of the perihepatic capsules associated with the pelvic inflammatory disease (PID). FHCS is not a serious disease, but if not treated properly, it can result in increased medical costs, prolonged treatment, and dissatisfaction with treatment. However, early recognition of FHCS in the emergency department can be difficult because its symptoms or physical findings may mimic many other diseases. Although contrast-enhanced computed tomography (CECT) is the useful imaging modality for recognition of FHCS, it is available only when a high suspicion is established. We performed point-of-care ultrasonography in an 18-year-old woman who had a sharp right upper quadrant (RUQ) abdominal pain without PID symptoms and found a thickened or three-layer hepatic capsule. These findings coincided with areas showing increased hepatic capsular enhancement in the arterial phase of CECT. These results show that if the thickened or three-layer hepatic capsule without evidence of a common cause of RUQ pain is observed on ultrasonography in women of childbearing age with RUQ abdominal pain, the physician can consider the possibility of FHCS.

Purpose: This study validated the influential relations between the effects of emergency care quality, credibility of 119 emergency medical technicians (119 EMTs), and perceived usefulness and attitude of emergency care, focusing on the moderating effect of protectors' characteristics (education, experience, age, and recognition of patient severity). Methods: This study was based on elaboration likelihood and technology acceptance models. In total, 172 protectors with experience in utilizing prehospital service were surveyed from April 1 to July 31, 2011. Results: The results showed that the emergency care quality and the credibility of 119 EMTs were the main determinants of the perceived usefulness and attitude of emergency care, irrespective of the protector's characteristics (p <.001). In addition, the findings showed that the protector's intention of emergency care had a moderating role. The impact of the quality of emergency care on its perceived usefulness was greater for high-level protectors (p <.001). By contrast, the impact of the credibility of 119 EMTs on the perceived usefulness of emergency care was greater for low-level protectors (p <.001). Conclusion: The protectors' characteristics have different influences on the relations between the effects of emergency care quality, the 119 EMT credibility, and the perceived usefulness and attitude of emergency care.

일반적으로 음성인식 시스템의 사용에 가장 저해되는 요소에는 배경 잡음을 들 수 있다. 잡음은 음성인식 시스템의 성능을 저하시키고, 이로 인해 사용 장소의 제약을 많이 받게 되는 이유가 된다. 이런 잡음의 영향을 해결하기 위해 본 논문에서는 음질 향상에 목적을 두고 신호단계에서부터 잡음성분을 제거하는 필터 중 FIR필터의 대역통과를 이용하여 일반적으로 사람의 음성 주파수 영역과 잡음 영역을 추출한 정보를 토대로 Wiener 필터를 구현, 그 성능을 향상하여, 전송되어지는 음성신호구간에서 잡음구간과 음성구간에 따라 잡음을 유연하게 처리하도록 구현하였다.

Purpose: The purpose of this survey was to investigate emergency department nurses' recognition of forensics nursing and their educational needs for forensics nursing education. Methods: Data were collected via questionnaires from 167 emergency department nurses who were working in 7 university hospitals. Nurses' experiences of trauma or accidents and their recognition of and educational needs for forensic nursing education were assessed. Results: All subjects reported having suffered bodily injury due to falling or serious traffic accidents; 92.2% reported having suffered bodily injury caused by suicide attempts; 91.6% reported having experienced physical violence or abuse; 76.0% reported having experienced sexual assault or abuse; 68.9% reported having experienced some difficulties during their nursing care due to lack of forensics knowledge; and 88.6% reported never having been trained in forensics nursing. The educational needs score for "forensics nursing" was 3.61; the needs score for "abuse- and violence-related education" was 3.65; the needs score for "incident data collection related education" was 3.47; and the needs score for "forensics theory related education" was 3.34. Conclusion: The findings of the study underscore a strong need to develop an educational program on forensics nursing for emergency department nurses.
