Purpose: We aimed to compare the transport time, the proportion of direct hospital visit and the emergency procedures between the current mountain rescue helicopter emergency medical service (HEMS) and physician-staffed mountain-rescue HEMS. Methods: During weekends from October 2, to November 21, 2010, 9 emergency physicians participated as HEMS staff in the mountain-rescue HEMS program of the Seoul fire department. Patient demographic data, transport time, proportion of direct hospital visits, and emergency procedures were recorded. We also collected data on HEMS mountain-rescued patients from June 1, to September 1, 2010, and we compared them to those for the study patients. After an eight-week trial of the HEMS, we performed a delphi survey to determine the attitude of the physician staff, as well as the feasibility of using a physician staff. Results: Twenty-four(24) patients were rescued from mountains by physician-staffed HEMS during the study period, and 35 patients were rescued during the pre-study period. Patient demographic findings were not statistically different between the two groups, but the transport time and the emergency procedures were. During the study period, the time from call to take-off was $6.1{\pm}4.1min$ (vs. $12.1{\pm}8.9min$ during the pre-study period, p-value=0.001), and the time from call to arrival at the scene was $15.0{\pm}4.8min$ (vs. $22.3{\pm}8.1min$ during the pre-study period, p-value=0.0001). The proportions of direct hospital visit were not different between the two groups, but more aggressive emergency procedures were implemented in the study group. The delphi survey showed positive agreement on indications for HEMS, rapidity of transport and overall satisfaction. Conclusion: A pilot trial of physician-staffed HEMS for mountain rescue showed rapid response and more aggressive performance of emergency procedures with high satisfaction among the attending physicians.

현재 자율주행차량 시장은 3레벨 자율주행차량을 상용화하고 있으나, 여전히 운전자의 주의를 필요로 한다. 3레벨 자율주행 이후 4레벨 자율주행차량에서 가장 주목되는 부분은 차량의 안정성이다. 3레벨과 다르게 4레벨 이후의 자율주행차량은 운전자의 부주의까지 포함하여 자율주행을 실시해야 하기 때문이다. 따라서 본 논문에서는 운전자가 부주의한 상황에서 긴급상황을 알리고 운전자의 반응을 인식하는 자율차량 안전을 위한 긴급상황 알림 및 운전자 반응 확인 시스템을 제안한다. 긴급상황 알림 및 운전자 반응 확인 시스템은 긴급상황 전달 모듈을 사용하여 긴급상황을 텍스트화하여 운전자에게 음성으로 전달하며 운전자 반응 확인 모듈을 사용하여 긴급상황에 대한 운전자의 반응을 인식하고 운전 권한을 운전자에게 넘길지 결정한다. 실험 결과, 긴급상황 전달 모듈의 HMM은 RNN보다 25%, LSTM보다 42.86% 빠른 속도로 음성을 학습했다. 운전자 반응 확인 모듈의 Tacotron2는 deep voice보다 약 20ms, deep mind 보다 약 50ms 더 빨리 텍스트를 음성으로 변환했다. 따라서 긴급상황 알림 및 운전자 반응 확인 시스템은 효율적으로 신경망 모델을 학습시키고, 실시간으로 운전자의 반응을 확인할 수 있다.

Construction sites have various risks, and safety managements are enforced based on the law such as Industrial Safety and Health Act, etc. Safety management by the law saves lives and preserves health of workers by removing and understanding risks in advance. When the emergency situation has come, poor response causes loss of lives and physical damages. This study suggests basic strategy that can mitigate the industrial disaster in all construction sites. A survey was conducted to identify the current safety consciousness and to evaluate first aid ability of coworkers. Finally, four measures were suggested: (1) designating muster points; (2) hiring occupational health managers; (3) increasing the first aid ability of coworkers; and (4) carrying safety brochure. The proposed suggestions can be helpful in mitigating the construction disaster, and in responding the major accident efficiently within a short time.

Reduction and prevention of human error is one of the major interests for the enhancement of system safety and availability in Nuclear Power Plants (NPPs). As human beings have become the weak point in the system safety, a systematic evaluation on human performance during emergency situation should be performed in advance to identify the potential vulnerability of human tasks. Though the data gathering and analysis from real field is an important precondition, there were no available data in nuclear field of korea. This paper presents the result of human performance analysis on emergency tasks in NNPs. Firstly, a task analysis was performed to identify the characteristics of operator tasks during emergency condition and to classify them into a set of generic emergency tasks. Secondly, simulation data were collected and analyzed for the emergency tasks using the full scope simulator of Younggwang NPPs. The analyzed human performance information cover the event diagnosis time, the execution time of each procedural step, observation parameters, typer of irrelevant response, pattern of communication among staffs, and so on. These performance data would be used for human reliability analysis and the research of human error as technical bases.

In general, the patients who transferred to the hospital by 119 rescue service at night go to the emergency room(ER) of general hospital rather than that of their nearby the 1st(clinic) and 2nd(local hospital) hospital. And the hospital is mainly selected not by 119 EMST but by patients or his/her conservators. Therefore we had studied retrospectively with emergency situation diary and medical chart for 697 patients of being transferred to one emergency medical center for 6 months since January 2004, and results are as follows. 1. The 280 patients(42.5%) of being transferred hospital at night by 119 rescue service were not emergency case and their average staying time in hospital was about $7.15{\pm}10.06$ minutes. 2. Transfer time was distributed in each time intervals of 1819, 2021, 2223, and 2401 and patients ratio in each intervals were 15.1%, 17.8%, 16.4%, and 15.2%. 3. In response of ambulance, the average time from the spot to the hospital was $14.53{\pm}9.27min$. and average distance of that was $7.95{\pm}9.21km$. 4. Diseases rather than traffic accidents or traumatic injury were main causes of ambulance calling and its value was 533(76.5%), and accidents were mainly occurred in patients' house and its value was 479(68.7%). 5. In time of transfer by 119 rescue service, hospital was mainly selected by patient/conservator and its value was 648(93.0%). In result. the hospital was selected not by EMST but by patient/conservator. 6. The case that the 1st grade EMT was rode in ambulance was 161(23.1%), and the case that 2nd EMT and emergency team member who educated for emergency were rode in ambulance were 504(72.3%). So the number of the 1st grade EMT was short in fire station of Kwangju metropolitan city than other city. 7. The first aids for patients before reaching hospital were limited to oxygen inhalation, airway control, and BLS for maintaining limbs and spine. So it seems to be a simple patients transfer. Consequently, to establish an efficient emergency medical system, it has been thought that it should be advanced a moderate education and public information about the appropriate use of emergency medical system toward citizen, and also need the hospital selection by the patients categorizing standards for 119 rescue service member, securing the 1st grade EMT, appropriate first-aids education, and securing professional human power in emergency room of the Ist(clinic) and 2nd(local hospital) hospital at night.
