  • This study researched the mutual relationship between elevator emergencies(sudden stops, entrapment) and power quality such as voltage interruptions or sags. To analyze the power quality at the elevator switchboard of an apartment, the on-line power quality(sag, swell, and interruption, etc.) were measured and error messages(under voltage error, etc.) in the elevator control room were researched. Also the performance and susceptibility for stops were evaluated and stated through the testing of three pieces of simulated test equipment with an EN12016(2004) standard setting and the magnitude and duration data of the measured sag or interruption. This paper will use these data in the analysis of the mutual relationship between power quality and elevator emergencies.

  • Access control is an essential security component in protecting sensitive data and services from unauthorized access to the resources in mission-critical Cyber-Physical Systems (CPSs). CPSs are different from conventional information processing systems in such that they involve interactions between the cyber world and the physical world. Therefore, existing access control models cannot be used directly and even become disabled in an emergency situation. This paper proposes an adaptive Access Control model for Emergences (AC4E) for mission-critical CPSs. The principal aim of AC4E is to control the criticalities in these systems by executing corresponding responsive actions. AC4E not only provides the ability to control access to data and services in normal situations, but also grants the correct set of access privileges, at the correct time, to the correct set of subjects in emergency situations. It can facilitate adaptively responsive actions altering the privileges to specific subjects in a proactive manner without the need for any explicit access requests. A semiformal validation of the AC4E model is presented, with respect to responsiveness, correctness, safety, non-repudiation and concurrency, respectively. Then a case study is given to demonstrate how the AC4E model detects, responds, and controls the emergency events for a typical CPS adaptively in a proactive manner. Eventually, a wide set of simulations and performance comparisons of the proposed AC4E model are presented.

  • Purpose: This study aimed to analyze the number of patients with and without medical history transported to the emergency department due to changes in daily temperature and season. Methods: Data on emergency activity sheet and daily weather were collected from March 2016 to February 2017 in the city of Gyeonggi-do. In total, 13,531 patients were transferred to the emergency department in 119 ambulance. Data were analyzed using the Statistical Package for the Social Sciences (version 21). Results: The daily average number of patients transferred was the highest in August and September, i.e., the summer season. The higher the daily highest and lowest temperatures, higher the daily average number of patients transferred. In contrast, patients with medical history of hypertension, diabetes, heart disease, cerebrovascular disease, and pulmonary disease had a higher incidence of transfers in the winter season and on days with lower temperature. Conclusion: The results indicate that as people become more active during the summer when temperatures are high, the chances of daily emergencies increases, whereas patients with medical history are more likely to experience emergencies when the temperatures were lower. Hence, 119 ambulances will have to be prepared in advance to deal with this trend.

  • Background: A contamination screening process for the local population in radiation emergencies is discussed. Materials and Methods: We present an overview of the relevant Korean governmental regulations that underpin the development of an effective response system. Moreover, case studies of foreign countries responding to mass casualties are presented, and indicate that responses should be able to handle a large demand for contamination screening of the local public as well as screening of the immediate victims of the incident. Results and Discussion: We propose operating procedures for an off-site contamination screening post operated by the local government for members of the public who have not been directly harmed in the accident. In order to devise screening categories, sorting strategies assessing contamination and exposure are discussed, as well as a psychological response system. Conclusion: This study will lead to the effective operation of contamination screening clinics if an accident occurs. Furthermore, the role of contamination screening clinics in the overall context of the radiation emergency treatment system should be clearly established.

  • Social welfare facilities are used by a wide range of local residents, including vulnerable populations such as the elderly, children, and people with disabilities. During emergencies like fires, confusion can arise as these individuals try to evacuate. Evacuation simulation results have shown that utilizing evacuation systems based on specific evacuation scenarios can significantly decrease the time required for evacuation compared to general evacuation procedures. By anticipating potential fires based on changes in social and facility environments, appropriate evacuation scenarios can be developed and applied to evacuation systems, thus contributing to the safety and security of individuals during emergencies. In conclusion, for social welfare facilities that serve a large number of people, it is necessary to expand the focus on performance-based design depending on the size of the facility, and to continuously develop and train for appropriate evacuation scenarios that align with changing facility environments.

  • The Civil Contingencies Act 2004 in the United Kingdom provides a comprehensive definition of "Emergency", calling upon the Uk's emergency management to deal with any disaster risk regardless of cause or source. Old contingency plans for civil defense and peacetime emergencies have been integrated into current integrated emergency management. In the UK, emergencies are managed by emergency services and other responders at the local level without direct involvement of central government. On top of this, a classified assessment of the risks of civil emergencies is also conducted on a regular basis, not only at the local level but also at the national level. This research looks into the Uk's emergency management system, including recent changes, and its risk assessment systems. Finally, the research draws policy implications for the development of Korea's disaster management mechanism as follows: 1) Korea should adopt an integrated emergency management system and combine civil defense with peacetime emergency planning, 2) it should create inter-operability between emergency responding organizations such as police, fire and ambulance, and finally 3) it must develop risk evaluating tools, such as a Community Risk Register and National Risk Register, both at the local and the national level. Last but not least, the UK emergency management system cannot be directly lifted from the UK and applied to risks and hazards faced by South Korea. Therefore, cross-cultural synthesis of many national approaches to emergency management is further required particularly for customizing policy to the particular needs of Korea.

  • Purpose: Dental emergencies vary from toothaches to oral and maxillofacial traumas. Because the number of dental emergency cases has increased recently, we analyzed characteristics of patients seen during the last 2 years, in an effort to find a trend. Methods: This study was carried out with emergency room patients visiting the Department of Oral and Maxillofacial Surgery from 2009 to 2010. Results: The total number of patients studied was 1,162; the ratio of males to females was 1.73:1. The most frequent age group was 0 to 9 years, followed by 20 to 29 years. Trauma (58.7%) was the most frequent cause followed by acute toothache, oral hemorrhage, infection, and temporomandibular (TMJ) disorder. In the trauma group, injuries of soft tissue and alveolus were prevalent. The most common causes of soft tissue injury were falls, safety violations and assault. The highest incidence of emergencies was seen in patients 0 to 9 years old (41.8%). The most common causes of jaw fracture were falls, assaults, and traffic accidents in that order. In the acute toothache group, most patients had pulpitis (41.2%). In the infection group, most had buccal space abscesses (40.0%). In the hemorrhage group, post-operative bleeding cases (80.5%) were the majority, and hemostasis was obtained mostly by pressure dressings. For the TMJ disorder group, masticatory muscle disorder (65.4%) was more common than TMJ dislocation. Conclusion: In this study, trauma was the most frequent reason for patients who visited the emergency room. However, acute toothache, hemorrhage, infection and TMJ disorders were also seen frequently. Dental emergency patients could be better treated by understanding patterns of dental emergencies and performing proper diagnoses.
