Signalized intersections are operated without a signal preemption control strategy in Korea, thus there is no priority treatment for an emergency vehicle passing through the intersections. In this paper, a signal preemption control strategy is introduced to improve the safety and operational efficiency of an emergency vehicle. Using the micro simulation tool, the effects on delay and travel speed of the signal preemption control strategy are analyzed for various traffic conditions to identify the general performance trends. Then, another simulation analysis is performed to verify the feasibility of the control strategy using real network data collected from field study. Results show that the preemption control strategy provides the positive impact on emergency vehicles' operation, but the positive impact is reduced as the v/c ratios increase. As expected, the average delays of the normal vehicles are slightly increased, but the magnitude is not significant. Therefore, it is expected that the introduction of the preemption control strategy in Korea would produce the positive social benefits.

When designing a routing protocol in a wireless sensor network, power efficiency and power balance must be considered above all for the life of the network. However, in application services such as environmental monitoring, the urgency and speed of data are more importantly required. In this paper, a routing protocol is proposed to satisfy different requirements for transmission of normal data and emergency data. In the case of general data, it is designed to minimize the power imbalance so that the network life can be extended. In the case of emergency data, the delay is minimized by controlling the power according to the power situation of the node.

Most of previous studies on civil servants' stress factors and job satisfaction have been focused on low job satisfaction caused by stress from role relations and human relations. In case of fire officers, however, their stress is expected to be influenced by their unique job characteristics such as risk, urgency, stand-by, and shift. Thus, this study divided fire officers'stress factors into job-related factors (risk, urgency, stand-by, alternation) and role-related factors (role conflict, role ambiguity, role overload), and empirically analyzed how these factors affect their job satisfaction. According to the results of this study, fire officers' job characteristics and their roles in the organization had a significant effect on their job satisfaction. Particularly, among the job-related factors, urgency and stand-by had a positive effect on job satisfaction, and among role-related factors, role conflict and role overload had a negative effect on job satisfaction. In addition, fire officers' stress and job satisfaction were significantly different according to their job (fire fighting, rescue and first aid, fire administration, others), and according to their workplace (fire fighting headquarters, fire station, 119 safety center).

본 연구에서는 기상청이 발표하는 기상긴급정보의 판단기준을 정립하기 위해 호우, 강풍의 기상관측 극값을 산출하고 현재 기상특보의 기준과 비교하였다. 최근 11년간의 기상극값의 분포에서 호우 주의보와 강풍 주의보는 관측된 219개 지점의 상위 0.5%에 해당하는 극값과 유의했다. 향후 본 논문에서 제시간 극값만으로 기상기급상황을 판단하는 현재의 특보 운영체계에서 지역적인 위험성의 노출과 취약성을 고려한 위험 판단의 기준을 제시하는 연구를 지속할 계획이다. 또, 본 연구에서 제시하고자 하는 기상긴급판단의 기준은 심각한 피해가 예상되는 악기상 현상이나, 시급한 판단이 필요한 기상현상을 판단하여 대국민에게 위험기상의 심각성과 시급한 경보를 전파하는데 활용하여 국민을 위험기상에 대한 대응 역량을 높이고자 한다.

WLAN 기술의 발전과 AP의 증가로 WLAN 기반 인터넷전화의 보급이 증가함에 따라 인터넷전화의 긴급 통화 서비스 제공이 중요한 문제가 되었다. 국내외에서는 긴급통화 서비스를 인터넷전화의 필수요건으로 규정하고, 기술표준을 제정하여 인터넷전화 사업자들에게 이를 적용하고 있다. WLAN 인터넷전화는 이동성이 보장되기 때문에 긴급통화 서비스 제공 시 사용자의 정확한 위치정보 전달이 중요하다. 본 논문에서는 위치정보 획득 방법을 기반으로 위치정보제공자와 연계를 통한 인터넷전화 긴급전화 서비스 제공 구조를 제안한다.

Purpose: In emergency situations such as earthquakes, heavy rains, typhoons, or fires, when quick delivery of emergency alerts is crucial, the hearing impaired are the ones who are the most disadvantaged and vulnerable when alerts are only delivered through auditory or text alerts. They can't perceive auditory information, and many have difficulties in fast understanding text-based alerts. Method: An alert system that can deliver pictograms for specific disaster situations has been devised. Then, a novel approach based on artificial intelligence has been studied so that the pictograms for specific disaster situations can be chosen instantly once a disaster alert is issued in text. Result: A disaster alert system that delivers pictograms for specific disaster situations was developed and a novel method has been suggested for automatic delivery. Conclusion: A system to instantaneously deliver disaster alert information in pictograms has been developed to improve alert delivery to the populations vulnerable to disaster due to hearing impairment by the instantaneous understanding of disaster situations through visual information.

This study is a fundamental research to determine the emergency evacuation roads considering road network function and connectivity. First of all, the functional aspects of the road networks are analyzed in the target area, Sejong city, by using degree centrality(DC) and closeness centrality(CC) from GIS based database. Secondly, how network connectivity makes a change in user's travel pattern and travel time and how it affects the whole network are analyzed using TransCAD simulation program. Finally, after performing cluster analysis of index, first and second emergency evacuation roads are determined by judging the characteristics of clusters. The results of this research will be helpful for making a decision to diminish secondary damages when confronting unexpected disasters.

VANET(Vehicular Ad hoc Network)시스템은 차량 간의 무선 통신을 통해 구성되는 임시적인 네트워크이다. 이 네트워크를 통행 차량사고 알림과 같은 긴급메시지를 보내게 되면, 운전자는 이를 알아차리고 대응 할 수 있게 된다. 이런 긴급메시지는 전파를 하는데 있어서 짧은 지연시간과 높은 신뢰성이 보장되어야 한다. 그리고 또 하나의 요소가 필요한데 그것은 방향성이다. 긴급메시지를 사고가 발생한 후방차량으로 알릴 수 있어야 하며, 이런 유용한 정보를 운전자 받아 들여 사고를 미연에 방지 할 수가 있다. 본 논문에서는 이러한 방향성을 고려하게 된다.
