Human-computer interaction is a discipline concerned with the design, evaluation, and implementation of interactive systems for human use. In this paper we suggest designing a smart deaf emergency application based on Human-Computer Interaction (HCI) principles whereas nowadays everything around us is becoming smart, People already have smartphones, smartwatches, smart cars, smart houses, and many other technologies that offer a wide range of useful options. So, a smart mobile application using Text Telephone or TeleTYpe technology (TTY) has been proposed to help people with deafness or impaired hearing to communicate and seek help in emergencies. Deaf people find it difficult to communicate with people, especially in emergency status. It is stipulated that deaf people In all societies must have equal rights to use emergency services as other people. With the proposed application the deafness or impaired hearing can request help with one touch, and the location will be determined, also the user status will be sent to the emergency services through the application, making it easier to reach them and provide them with assistance. The application contains several classifications and emergency status (traffic, police, road safety, ambulance, fire fighting). The expected results from this design are interactive, experiential, efficient, and comprehensive features of human-computer interactive technology which may achieve user satisfaction.

Purpose: Ths study aims to examine characteristics of patients using emergency room after execution of five-day workweek system by government and provide basic materials for operation of efficient emergency room. Methods: Data were collected tbrough medical records of patients visiting emergency room from July of 2004 to October of 2006 and they were analyzed with SPSSlPC 10.0. Conclusion : 1. The number of patients visiting emergency room was average 16.7 persons a day in 2004, 17.5 in 2005 and 18.6 in 2006 and it was found that it was increasing every year since the execution of five-day workweek system 2. Gender distribution of subjects using emergency room was higher in male than in female every year. 3. Means of transport to emergency room were mostly private car and others(public transport or on foot), but use of ambulance was increasing. 4. Residential areas of subjects were mostly 'Myeon area' in 2004~2005, but it was changed to residents at 'Eup area' in 2006. 5. Distribution of patients by medical departments was highest in internal medicine and surgery in 2004~2006 and rate of visiting pediatrics was increasing every year. 6. Time to stay at emergency room was most at 'below 30 min'. in 2004~2006, but cases of stay for 'more than 2 hours' were increasing every year. 7. On presence or absence of trauma in patients visiting emergency room, rate of visit to emergency room with 'no trauma' was higher and this result was increasing every year. 8. As a result of classifying severity of patients visiting emergency room, use rate of emergency room by 'non-emergency' patients was over 90% in 2004~2006 and such a phenomenon was deepened in 2006 compared to that in 2004. 9. Measures after emergency care of patients were most in case of 'discharge' in 2004~2006, but cases of admission to hospital after emergency care were increased every year. 10. According to use of emergency room by a day of the week, use on Sunday was most frequent in 2004~2006, but use on Friday the day before holiday was increasing. 11. According to distribution by age, use by those between '40~49' was most in 2004~2005, but use by those 'below 10' was most in 2006. 12. According to time to visit emergency room, using emergency room at "15:31~23:30 was most in 2004~2006, cases of visiting emergency room at day working hour were decreased every year and those at evening and night working hours were increased. Conclusion: In sum, it was found that characteristics of patients visiting emergency room and their actual status were changed after the execution of five-day workweek system and efforts to rearrange emergency medical system are required.

The purpose of this study is to investigate the effect of high quality CPR using the 4 types of rescue device equipment and chest compressions energy measurement in pre-hospital settings. So, we used the mode to insert load cell in ALS Skill master Manikin to develop CFMM(Compression Force Measurement Manikin) on main stretcher, CPR board, long spine board, scoop stretcher and floor. And, our research team could know that the main stretcher needed average force of 32.55 (${\pm}1.01$) kg, CPR board of 27.23 (${\pm}1.08$) kg, long spine board of 27.13 (${\pm}1.18$) kg, Scoop Stretcher of 27.38 (${\pm}1.05$) kg and Floor of 27.24 (${\pm}0.93$) kg. CPR board must be necessary in the case of CPR on main stretcher in a moving ambulance. But if the condition of patient's back surface is the removable stretcher and the long spine plate, the patient doesn't have to be spent time to use a CPR board. Furthermore, this research suggests to consider that how to take advantage of the education to students for the equipment to check in real time the energy(kg) requirement of chest compressions.

This study aimed at evaluating and developing 119 emergency medical technicians' prehospital care for non-traumatic cardiac arrest. Total 322 EMT in Chungnam province and Daejeon city filled out the self-administered questionnaire. The data were analyzed by SPSS 18.0 for descriptive statistics. Among the 322 EMT, 309 (97%) and 169(53%) always or almost performed CPR and AED for nontraumatic cardiac arrest patient, respectively. Among the advanced EMT and nurse, IV were sometimes or not performed at 94.7% and medication including epinephrine which commonly used for survival of cardiac arrest were treated just at 9.3 % (14 person). The reason they did not perform each procedure for airway management, AED or IV was lack of manpower, limit of time or joggle of ambulance and legal restrictions. In conclusion, to increase survival rate of non-traumatic cardiac arrest in out-of-hospital, it is necessary to increase manpower, legal protection of EMS, establishment of standard operating procedure, practice for improvement technique and use of medication for ACLS.

Background: Extracorporeal membrane oxygenation (ECMO) has been successfully used as a method for the interhospital transportation of critically ill patients. In South Korea, a well-established ECMO interhospital transport system is lacking due to limited resources. We developed a simplified ECMO transport system without mechanical ventilation for use by public emergency medical services. Methods: Eighteen patients utilized our ECMO transport system from December 2011 to September 2015. We retrospectively analyzed the indications for ECMO, the patient status during transport, and the patient outcomes. Results: All transport was conducted on the ground by ambulance. The distances covered ranged from 26 to 408 km (mean, $65.9{\pm}88.1km$) and the average transport time was $56.1{\pm}57.3minutes$ (range, 30 to 280 minutes). All patients were transported without adverse events. After transport, 4 patients (22.2%) underwent lung transplantation because of interstitial lung disease. Eight patients who had severe acute respiratory distress syndrome showed recovery of heart and lung function after ECMO therapy. A total of 13 patients (70.6%) were successfully taken off ECMO, and 11 patients (61.1%) survived. Conclusion: Our ECMO transport system without mechanical ventilation can be considered a safe and useful method for interhospital transport and could be a good alternative option for ECMO transport in Korean hospitals with limited resources.

The objective of this paper is to examine the proportion and characteristics of non-emergent patients at emergency departments. The observational survey was conducted using a structured form used by emergency medicine specialists or senior residents on June 7-20, 2005. 1,526 patients at ten emergency centers took part in this study. The structural form contained type of insurance, route and means of emergency department (ED) visit, triage based on the Manchester Triage Scale(MTS)-modified criteria, emergency level based on the government defined rule, type of emergency centers (Regional Emergency Medical Center; REMC, Local Emergency Medical Center; LEMC, Local Emergency Agency; LEA), as well as patient's general information. Data were analyzed using SAS statistical program(V.8.2). Descriptive analysis was performed to describe the magnitude of non-emergent patients. ${\chi}^2-analysis$ and logistic regression analysis was performed to identify the nonurgent patients' characteristics. In the MTS-modified criteria, we found a 15.3% rate of non-emergent patients. This rate differed from that of non-emergent patients obtained using government's rule. In particular, there were inaccuracies in the definition of government rule on non-emergent patients, so it is necessary to apply the new government rule regarding classification of non-emergent patients. There were significant differences in the rate of non-emergent patients according to type of ED, means of ED visit, time to visit, and insurance. Non-emergent patients are more likely to visit a D-type ED(LEA having less than 20,000 patients annually), not to use ambulance, to have 'Automobile Insurance, Industrial Accident Compensation Insurance, or pay out-of-pocket'. Non-emergent patients tend to visit ED due to illness rather than injury. Further studies on the development' of triage scale and reexamination of the government's rule on emergency visits are required for future policy in this area.

This paper aimed to statistically analyze the impact of fire needs not considered in previous reports based on preventive and preparedness strategies of fire administration and fire budget.. The panel data came from 16 metropolitan councils from 2008 to 2018 and was statistically analyzed based on the preventive measures of the fire administration (agreement for building permission, specific target for fire-fighting, public use facilities, and special fire inspection [SFI]), preparedness of the fire administration (fire safety education [FSE]), response of the fire administration (mobilization for fire suppression [MFS] and mobilization for ambulance service [MAS]), and fire budget. In the results, SFI, FSE, and MFS had a significant negative influence on the fire budget. Meanwhile, MAS had a significant positive effect on the fire budget (p < 0.01). These results reflect public policy in Korea; there has been a paradigm shift in fire administration: from disaster acceptance (focusing on recovery) to disaster response (focusing on field response) to disaster preparedness (focusing on preparedness).

Experimental research is needed to provide information on the removal of bloodstains since washing clothes contaminated with blood is necessary for medical related fields (such as ambulance workers and doctors) as well as for women of childbearing age. This study investigated efficient washing conditions for the removal of bloodstains with a focus on washing temperature, fiber type and blood ageing time. Polyester/cotton fabric showed the highest detergency from among three fabrics that were influenced by the composition of the fiber and the structure of the yarn and fabric. When examining the effect of detergent, it was concluded that the alkalinity over pH 10 was essential to remove bloodstains and that auxiliary agents such as soil antiredeposition agents and bleach had a significant effect on the removal of bloodstains. Washing temperature showed the highest detergency at 20℃ due to the activity of the enzyme without the denaturalization of blood. Blood-ageing influenced detergency by inducing changes in the adsorption area and chemical bond. A combination of methods such as quick removal after contamination, use of alkaline detergents including soil antiredeposition agents and bleach, and low-temperature washing could help remove bloodstains.

The X-ray unit developed by this study is to diagnose emergency cases which is too far from a hospital and to classify the patients. We have to use the X-ray in a ambulance or the scene of an accident where we cannot use the AC220 outlet because of the distance from a hospital as well. The X-ray unit developed has a characteristics as follows. First of all, as the unit has a condenser in itself where there is no electric supply, we can use the X-ray inspector in a mountain area or a island. Second, we can detect by digital detector the information taken by X-ray from DC 12[V] electricity and store as a form of file. A control circuit can secure the reliability of the X-ray unit by using the Pic16F84A X-ray and provide various functions. The X-ray unit which suits remote emergency system can be efficiently used for the emergent cases who is too far from a doctor and a hospital or in the situation where it is difficult to diagnose, transcribe and treat simultaneously.
