Currently, there are a total of 68 emergency rooms based on Seoul, South Korea, and there is a portal site that allows you to inquire the location of the emergency room, but it is difficult to use in an actual emergency situation because it consists of selecting a gu and a self-governing dong. In addition, it may be more efficient to go to the emergency room directly because you may miss the golden time necessary for survival in a situation where you call 119 and wait for the rescue team. Therefore, in this paper, we propose a service that can quickly search the location of the emergency room based on a specific location through various functions supported by MongoDB. After downloading emergency room location data based on Seoul Metropolitan City, storing it in MongoDB, processing the data through various processing techniques, and applying a spatial index, you can query the emergency room based on distance from a specific location in real time.

An aerial relay system utilizing an unmanned aerial vehicle(UAV) or drone is addressed for event-driven operations such as temporary communication services for disaster affected area, military and first responder support. UAV relay system (URS) targets to provide a reliable communication service to a remote user equipment or an operator, therefore, a fast UAV placement to guarantee a minimum quality of service(QoS) is important when an operation is requested. Researches on UAV utilization in communication systems mostly target to derive the optimal position of UAV to maximize the performance, however, fast deployment of UAV is much more important than optimal placement under emergency situations. To this end, this paper derives the feasible area for UAV placement, investigates the effect of performance requirements on that area, and suggests UAV placement to certainly guarantee the performance requirements. Simulation results demonstrate that the feasible area derived in this paper matches that obtained by an exhaustive search.

Recently, a fire suddenly broke out in a crowded theater, and many people were unable to find an escape route, becoming entangled, injured, and suffocating from smoke inhalation, resulting in a large-scale fire accident. Even though most of the people were young, they were unable to evacuate. If they had been elderly, it could have resulted in greater casualties. In particular, since it is difficult to receive accurate location information from GPS indoor, there is an urgent need for location-based services using beacons and an emergency evacuation system that intuitively shows evacuation routes in augmented reality using smart-phones. In this paper, an augmented reality-based emergency evacuation smartphone app was developed based on identifying fire locations and evacuation routes using beacons and fire sensors (IoT). In the future, if the proposed system is applied to indoor spaces where people are crowded, rapid evacuation will be possible even in a sudden fire accident, minimizing human damage.

Purpose: This study was done to describe utilization status of emergency medical service for children at one university affiliated hospital located in Seoul. Data were obtained from the medical records of patients under 13 years of age who visited the ER from January 1 to December 31, 2006. Method: Medical records missing the time of discharge were excluded in the analysis of waiting time, which resulted in 19,766 cases. Data were analyzed using SPSS WIN 14.0 version. Result: There were slightly more boys (58.4%), average age of the children was 3.97 years of age. More children at the aged 1 to 3 years (51.3%) visited the ER. Fever was the most frequent complaint: 5,180 cases (24.38%). The other complaints were head or facial laceration (10.55%), vomiting (9.63%), abdominal pain (8.06%), cough (7.67%), and painful limb swelling (6.34%). Average waiting time before the first medical examination was 17 minutes, and average ER stay time was 3 hours and 23 minutes. Conclusion: The results suggest the need to assign a nurse specialist for pediatric ER to provide more efficient care for the children. Also, extra staff assignment during the evening shift or extending office hours of local pediatricians should be considered.

From January, 2004 to July, 2007, 97 patients were diagnosed with Acute coronary syndrome(ACS) in Emergency Medical Center in Jecheon City in Korea. Among 97 patients, the prehospital assessment rates were as follows ; blood pressure check(27.80%, pulse rate check(33.0%), respiration check(23.7%). In hospital emergency care, oxygen supply was 52.6%, absolute bed rest was 12.4%, electrocardiogram(EKG) check was 4.1%, and nitroglycerin and intravenous fluid therapy was 0%. Therefore, ACS patients have not received sufficient prehospital cares till now. In order to improve the proficiency of the first aid emergency medical technicians(EMTs), it is necessary to provide the continuing On-the-job training(OJT) programs for prehospital emergency care.

Purpose: To examine patient satisfaction with nursing care and the difference of patient satisfaction by the characteristics of emergency care service in the center for emergency medicine. Method: We surveyed 145 patients who visited Pusan-Wide Emergency Medical Center from Nov 01, 2003 to Nov 30, 2003. Patient satisfaction was assessed by asking patients and medical records reviewed to obtain the characteristics of emergency care service. Results: The mean score of patient satisfaction with nursing care was 3.12. For patient satisfaction, 'The nurse seemed earnestly concerned about my pain, fear, and anxiety' represented highest score (3.58). Patient satisfaction according to the general characteristics of patients was revealed as significantly high for the higher educated and the older. Patient satisfaction by the characteristics of emergency care service was significantly higher in no-wait group. Conclusion: Also, the fundamental of nursing, like respect for human, was maintained in emergency setting, the hospital's administration has implemented service for a high level of satisfaction with nursing care up to the expectations of the patients for with the staff and medical equipment.
