  • 비상시 또는 화재발생시에 인명의 원활한 대피를 위한 피난유도설비는 매우 중요하다. 이중 유도등은 상시점등되어 있어야할 뿐만 아니라 비상전원이 필요하므로 경제적 손실이 커지게 된다. 본 연구에서는 태양전지, 쵸퍼, 인버터로 태양광발전시스템을 구성하여 태양광으로부터 발생되는 에너지를 축전지에 저장시킨 후, half-bridge 인버터를 이용하여 상용전원없이 유도등이 점등되도록 제어하였다. 그 결과 상용전원으로 유도등 점등시와 제안한 시스템에 의한 유도등 점등결과가 동일함을 입증하고 그 유용성을 확인하였다.

  • It has been criticized that conventional human reliability analysis (HRA) methodologies for probabilistic safety assessment (PSA) have been focused on the quantification of human error probability (HEP) without detailed analysis of human cognitive processes such as situation assessment or decision-making which are crticial to successful response to emergency situations. This paper introduces a new human reliability analysis (HRA) methodology, AGAPE-ET (A guidance And Procedure for Human Error Analysis for Emergency Tasks), focused on the qualitative error analysis of emergency tasks from the viewpoint of the performance of human cognitive function. The AGAPE-ET method is based on the simplified cognitive model and a taxonomy of influencing factors. By each cognitive function, error causes or error-likely situations have been identified considering the characteristics of the performance of each cognitive function and influencing mechanism of PIFs on the cognitive function. Then, overall human error analysis process is designed considering the cognitive demand of the required task. The application to an emergency task shows that the proposed method is useful to identify task vulnerabilities associated with the performance of emergency tasks.

  • When an emergency situation happens in buildings, the top priority is to ensure the occupant from danger as soon as possible. Achieving that goal is a multifaceted and difficult task. However, current evacuation systems have many deficiencies in dealing with the emergency in multi-level structures. The shortage of abilities to continuously update database, predict the future situation and provide the information to users with contextual information is the limit in current systems. Thus, it is very crucial to introduce Evacuation Information System (EIS), which is able to respond quickly to the emergency, and transfer the information to both the administrator and the occupant. The main purpose of this paper is to build EIS on the basis of the indoor Geographical Information System (GIS). When the emergency happens, EIS gives the instruction to Emergency Response Model (ERM) at once. ERM carries out the order and calculates the optimal evacuation routes, then sends the result to EIS. At last, EIS transmits evacuation messages to the occupant who implements evacuation plan. This paper highlights the benefits of EIS in two aspects. One is that EIS can update the data continuously to support evacuation strategy-making. The other is that it can transmit evacuation messages to both the administrator and the occupant.

  • The purpose of EMS is to provide emergency patients with prompt and suitable emergency treatments therefore it saves their lives and makes them recover fast to return to normal. The purpose of correctional administration is to return inmates to society as sound citizens after their service by providing various correctional education, reformational programs, vocational training and etc. In this way, the aim of correctional administration and EMS is like mutual agreement by their returning to society safely. Therefore this study makes some propositions like the followings for the safety between many inmates who can have physical injury and exposure to diseases caused by particularity of subculture within correctional institutions and the staffs who work for them. It is said about efficient pre-hospital EMS through various causes of emergency situation in the correctional institution, system, manpower, facility, equipments and problems and so on. 1. Recruit the first-rate EMT(emergency medical technician) as central role of pre-hospital EMS according to each correctional institution and working terms. 2. Equip specialized transference system with symptom of patients and purpose of transference. 3. Emergency medical equipments and first-aid medicines should be equipped for field and ambulance. 4. Educate correctional officers as first responders and inmates within correctional institutions about systematic emergency treatment.

  • This study was carried out to improve service efficiency and to cope with a emergency situation in emergency radiography, through analysis of the radiographic distribution and literature cited about emergency care. Data collection of radiographic distribution was surveyed for 761 emergency outpatients who visit during JAN, 1994 at ER of the general hospital in Pusan city. The results is as follows: Emergency radiography rate of simple radiography was 61.1 %, special radiography 2.5 %, CT 12.6 %, and ultrasonography 6.7 %. In simple radiography rate, a high rate was distributed on male(63.6 %), thoracicsurgery part(90.0%), admission patient(74.9 %), and long stayed patient at ER. In special raiography rate, a high rate was observed in urologic part(28.6%), and in CT rate, observed neurosurgery part(49.2 %) and neurologic part(36.7%). Ultrasonography rate was high for female(8.8 %) and internal medicine part(15.9 %). There are distributed regional radiography rate in radiographic type that chest(55.3 %) is high in the simple radiography, urinary system(1.2%) in the special study, and brain(40.0 %) in the CT. Regional radiography rate according to diagnostic department also was showed highly for head(64.6%) in neurosurgery, chest(90.0%) in thoracic-surgery, abdomen(58.0%) in general-surgery, spine (40.0% ) in neuro-surgery, and pelvis(15.9%), upper extrimity(20.5%), and lower extrimity(31.8%) in orthopedic-surgery each. Mean radiographic case number per patient of simple radiography was sinificant on sex, age, transfer relation in both total and radiographic patients(p<0.05). Mean radiographic case number was highly distributed on male(2.2 case number) in sex, on thirties(2.7) in age, transfered patient(2.7) in patient type, and on neurosurgery(3.4) in diagnostic charged part. Total radiographic case number in regional part was highly distributed on chest(499 case number). Considering the above results, emergency radiographer should take care of the elder patient in emergency radiography and get hold of injury mechanism to decrease possible secondary injury during radiography. Because of high radiography rate of urinary system in special study, radiographer should know well about dealing with contrastmedia administration and related instrument. All radiographer who take charge emergency patient should cope with a emergency situation during radiography, Because head trauma patients is very important in patient care, especilly in CT at night, charged doctor should be always silted with CT room and monitoring-patient. Radiography was reqested by many diagnostic department in ER. Considering that rate of simple radiography is high, special room for emergency radiography should be established in ER area, and the radiographer of this room should be stationed radiologic technician who is career and can implement emergency patient care.

  • The proposed application design for emergency medical system includes the functions that help securing the window of opportunity for the patients in an emergency situation and efficiently link rescue agency, emergency medical treatment center and patients together. First, the treatment time can be saved at the emergency room by understanding the patient's condition by entering his/her health information such as anamnesis, family history, social history and blood type together with an identification number. Also, if the siren function which signals whereabouts of patients to the rescue crew is used, it will be much easier to find the location of the patient in need. The design allows rescue crew to call the patient to check whether he/she is conscious or not. Just by receiving the call, he/she will be deemed conscious.
