  • This paper is concerned with simulation exercises used to train key response agencies for crisis situations. While 'multi-agency' simulations are increasingly acknowledged as a necessary and significant training tool for emergency response organisations, many current crisis simulations are still focused on the revision of existing response plans only. However, a crisis requires a rapid reaction, yet in contrast to an 'emergency', the risks for critical decision makers in crisis situations are difficult to measure, owing to their ill-structure. In other words, a crisis situation is likely to create great uncertainty, unfamiliarity and complexity, and consequently should be managed by adaptive or second order expertise and techniques, rather than routine or structured responses. In this context, the paper attempts to prove that the current practices of simulation exercises might not be good enough for uncertain, unfamiliar, and complex 'crisis' situations, in particular, by conducting case studies of two different underground fire crises in Korea (Daegu Subway Fire 2003) and the UK (King's Cross Fire 1987). Finally, it is suggested that the three abilities: 'flexibility', 'improvisation' and 'creativity' are critical in responding to a crisis situation.

  • This paper introduces a moving object tracing system using network-connected CCTV and smartphone. In an emergency situation, a smartphone of the reporter gains its GPS information and sends that to the central server. The central server stores received GPS information as a dangerous area in the database and keeps sending the order of tracing the reporter to a network-connected CCTV which can film the reporter. At the same time, the central server sends pictures of the reporter to his or her family and related organization in order to handle the emergency situation as soon as possible. In addition, when a reporter want to know the risk around destination, the central server informs dangerous areas to the reporter by using smart phone application and database of a danger spot.

  • Recently, the intelligent transportation system (ITS) that provides driver convenience and reduces the number of road casualties is in the spotlight. ITS must quickly deal with the emergency situation and provide information which drivers need. In ITS, a different channel will be assigned for each service to provide the service efficiently. However, if the channel is used at an emergency situation, the service cannot be provided immediately. For overcome this problem, we introduce the cognitive radio technology into ITS and propose a new spectrum sensing method in this paper.

  • When the mountain accident occurred, the accident victims should inform anyone of information of the location and accident situation rapidly. But if you are in the radio shadow area where you cannot use GPS, 3G/4G, and wireless communication, you can't inform someone your accidents. In this paper, we suggest the emergency rescue request notification service in situation that victims can't report their accidents. This service is to send request message for rescue in radio shadow area, in mountain accident, by BLE(Bluetooth Low Energy).

  • AFLS (Adaptive front lighting System) is being applied to improve safety in driving automotive at night. Safe embedded system for controlling head-lamp has to be tightly designed by considering safety requirement of hardware-dependent software, which is embedded in automotive ECU(Electronic Control Unit) hardware under severe environmental noise. In this paper, we propose an adaptive headlight controller with newly-designed symmetric angle sensor compensator, which is integrated with ECU-based adaptive front light system. The proposed system, on which additional backup hardware and emergency control algorithm are integrated, effectively detects abnormal situation and restore safe status of controlling the light-angle in AFLS operations by comparing result in symmetric angle sensor. The controlled angle value is traced into internal memory in runtime and will be continuously compared with the pre-defined lookup table (LUT) with symmetric angle value, which is used in normal operation. The watch-dog concept, which is based on using angle sensor and control-value tracer, enables quick response to restore safe light-controlling state by performing the backup sequence in emergency situation.

  • Recently our country was entering a high-tech society with social and economic development. However, the individual's ability to respond to disasters is lowered by the increase in complexity society. Accurate situation assessment and disaster response by a margin of personal information that can identify when a disaster has been difficult. Until now, by leveraging Standard speaker was the emergency alert broadcast. However, it was difficult to have regular speakers reverberation, a distinct attenuation of sound by listening to the sound, etc. due to the reflection of sound. By using a directional speaker that is characteristic of the sound attenuation of sound is straight to solve this problem and obtain feedback on measures that can effectively provide the oocytes to a valid information on a disaster situation and the evacuation.

  • This study was carried out to improve service efficiency and to cope with a emergency situation in emergency radiography, through analysis of the radiographic distriution and literature cited about emergency care. Data collection of radiographic distribution was surveyed for 1270 emergency outpatients who visit during JAN, 2009at ER of the general hospital in Gwang city. The results is as follows : Emergency radiography rate of simple radiography was 56.6%, special radiography 2. 5%, CT 34.2%, and ultrasonography 6.7%, In simple radiography rate. a high rate was distributed on male(63.6%), thoracicsurgery part(90.0%), admission patient(77.9%), and long stayed patient at ER. In special raiography rate, a high rate was obsurved in urologic part(28.6%), and in CT rate, observed neurosurgerty 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 radio-graphic 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 neuro surgery, 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 radiopraphic 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, transferred patient(2.7) in patient type, and on nurosurgery(3.4) in diagnostic charged part. Total radiographic case number in regional party was highly distributed on chest(998 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, 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 sitted 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 radiopraphy should be established in ER area, and the radioprapher of this room should be stationed radiologic technician who is career and can implement emergency patient care and The disposition of men which is appropriate with emergency patient increase is necessary.

  • The majority of acute toxic poisoning occur via oral route. The most important emergency treatment of acute poisoning are gastric lavage. Gastric lavage should be considered a patient has ingested a potentially life-threatening amount of a poison and the procedure can be undertaken within 60 mins of ingestion. But, gastric lavage does not consist properly in the cases of emergency situation or an inexperienced doctors treat. The purpose of this study was to determine whether gastric lavage is performed properly. Eighty patients were enrolled in the study in 12-month period from January to December 2002. A retrospective chart review was performed on patients identified as drug overdose who admitted to ER. To assess whether there was a subgroup of patients who may have been candidates for the initiation of gastric lavage in the ER, the patients divided in two groups by time interval from toxin ingestion to ER arrival. The group 1 that admit within 60 minutes after drug ingestion was 38 cases ($47.5\%$), and the group 2 patient who admitted after 60 minutes was 42 cases ($52.5\%$). The average age was $44\pm19$ years in group 1, and $48\pm24$ years in group 2. There were no differences in sexual distribution of two groups. The mean time interval was $49\pm20$ minutes in the group $1,258\pm190$ minutes in the group 2. Only thirty ($37.5\%$) of the patients had an overdose for which the treatment of gastric lavage was potentially feasible according to guideline. The correctly performed gastric lavage was 18 ($47.4\%$) in group 1, 12 ($28.6\%$) in group 2. We must enforce education about the gastric lavage, and do so that may treat according to guideline.

  • According to U.S. NTSB, from 1989 to 1992, Situation Awareness (SA) was a major factor causing 80% of all aircraft accidents in scheduled airlines. Therefore, the prevention of accidents through effective training in SA became a pivot in aviation safety. Furthermore, during the past 10 years, since all helicopter accidents in Korea were caused by the factors related to SA, an appropriate countermeasure has been required. This study, which uses survey data, examines various factors related to SA that could affect helicopter pilots. Recognition of and countermeasures for the factors in emergency situations were analyzed. The results show that, while the factors associated with SA and vigilance have lower correlations with each other, the factors associated with recognition, diagnosis, and generation and implementation of solutions have higher correlations with each other. Thus, the results demonstrate the need for better SA through educational training.
