  • This paper proposes a fire shunt guidance system model based on rule, it presents suitable shunt route in real-time according to collected fire information of the building inside using wireless sensor networks. So, this system model is composed of the sensor alert module, the behavior suggestion module, and the emergency device control module. The sensor alert module uses rule-base algorithm that monitored the information to collect periodically in wireless sensor networks. And, the behavior suggestion module proposed a suitable behavior, this module supports to judge the fire area with danger sensor list. Additional, the emergency device control module controls a related emergency device according to the suggested behavior and to present on a control screen. We experiment the fire shunt guidance system based on Internet Web for operation verification of the proposed system. Consequently, this study supports people safety with the behavior suggestion according to the context information when an emergency situation happens.

  • The 'alert' is to provide a signal or information beforehand, in order to prepare against situations in which abrupt incidents or disasters are expected. In other words, the purpose of alert is to help people or respondents to take precautions against and quickly cope with disasters or incidents, before those actually occur. This paper draws requirements of alert system from definitions of the alert and cases of it home and abroad. Following requirements of alert system are derived to allow subjects responsible for alert issue to quickly handle changes of situations; 1) identification of subjects responsible for alert issue, 2) use of definite terms regarding alert levels, for prompt actions, and 3) distinct separations among alert levels. This paper suggests improvement directions by extracting several problems of National Crisis Alert System according to such requirements.

  • The location information of wired 112, 119 emergency call is provided immediately by subscriber database of KT. But emergency call made by mobile phone should be ask location information to mobile network. This paper proposes the network protocol for mobile emergency service refer to TIA/EIA/J-STD-036-A with reviews about technical issues, legacy factors and related researches. The mobile emergency service is divided to mobile emergency rescue service and mobile emergency alert service. The network reference model for mobile emergency rescue service is released in domestic sector. In this paper, the interfaces between modules of the network reference model, and service scenarios, message flows are defined. Supplement to mobile emergency rescue service, the network reference model, interfaces and message flows for mobile emergency alert service are developed.

  • Currently, roadway operation agencies provide interior zones of tunnels with emergency information including crash, fire, and vehicles' stop, through state-of-the-art technologies such as variable message signs and radio-based broadcast systems. However, when coping with an emergency in tunnel interior zones, such information could be too late for drivers to access. A radio-based emergency alert system at the access zones of freeway tunnels, on the other hand,could be a good alternative for solving this problem. Therefore, the objective of this study is to assess user acceptability of such an alternative system. To carry out this study, an online survey was conducted on 762 drivers, and the survey results were analyzed using a structural equation modeling to identify factors affecting acceptability of the proposed system. As a result, driver characteristics such as age group, driving frequency, and driving career, utilization of conventional traffic information, and usefulness of conventional traffic information have a positive impact on acceptability. It is expected that the findings of the study will be a basis to effectively address and deploy a new emergency alert system at the access zones of freeway tunnels.

  • The types of service using location information are being various and extending its domain as wireless internet technology is developing and its application part is widespread, so it is prospected that LBS (Location-Based Services) will be killer application in wireless internet services. The MODB (Moving Object Database) stores and manages very large current/ past moving object data, so it is very important part in LBS platform. The performance of LBS platform is tightly depending on the performance of this MODB. The other important part is alerting engine in LBS platform, which is system to transmit various value-added information or notify emergency information to mobile phone after triggering specified events. This alert engine is supported as extended function of MODB, that is to say, the alerting function is closely related with MODB. So alert cartridge on MODB must provide not only moving point triggering about going into, going out specified geographical area but also batch alerting about nearest neighbor from specified geographical area. In this paper, we study of extended part on MODB to support the alert engine. And we design alert engine cartridge on MODB before implementing the system.

  • Purpose: In patients with glufosinate poisoning, severe neurological symptoms may be closely related to a poor prognosis, but their appearance may be delayed. Therefore, this study aimed to determine whether the Acute Physiology and Chronic Health Evaluation II (APACHE II) score could predict the neurological prognosis in patients with glufosinate poisoning who present to the emergency room with alert mental status. Methods: This study was conducted retrospectively through a chart review for patients over 18 years who presented to a single emergency medical center from January 2018 to December 2022 due to glufosinate poisoning. Patients were divided into groups with a good neurological prognosis (Cerebral Performance Category [CPC] Scale 1 or 2) and a poor prognosis (CPC Scale 3, 4, or 5) to identify whether any variables showed significant differences between the two groups. Results: There were 66 patients (67.3%) with good neurological prognoses and 32 (32.8%) with poor prognoses. In the multivariate logistic analysis, the APACHE II score, serum amylase, and co-ingestion of alcohol showed significant results, with odds ratios of 1.387 (95% confidence interval [CI], 1.027-1.844), 1.017 (95% CI, 1.002-1.032), and 0.196 (95% CI, 0.040-0.948), respectively. With an APACHE II score cutoff of 6.5, the AUC was 0.826 (95% CI, 0.746-0.912). The cutoff of serum amylase was 75.5 U/L, with an AUC was 0.761 (95% CI, 0.652-0.844), and the AUC of no co-ingestion with alcohol was 0.629 (95% CI, 0.527-0.722). Conclusion: The APACHE II score could be a useful indicator for predicting the neurological prognosis of patients with glufosinate poisoning who have alert mental status.

  • Current standard for T-DMB Automatic Emergency Alert Service(AEAS) contains controversial problems in service signaling. In this paper, we first describe two important characteristics of AEAS which hinder normal MCI service signaling: Common Service and Aperiodic Service. Next, we propose four method to overcome the problems, followed by the characteristics of each method. In this analysis, current T-DMB standard, the broadcasting system, and receivers are the major player to decide the optimum service signaling method. This analysis will be also applied to the design of transmission standard for other media such as cable, satellite, the Internet, etc.

  • 2005년 국내에서 본방송을 실시한 DMB는 모바일 방송이라는 새로운 방송 이용 환경을 창출하였다. 더불어 기존 TV를 통한 재난 방송의 사각지대로 거론되어 온 야외, 정전, 해상, 이동 환경에서 재난정보를 전달할 수 있어 방송 매체로 평가되면서, 다양한 기술 개발이 진행되었다. KBS는 DMB를 통한 재난경보방송 기술을 구현하여 2008년 제주도 지역 실험방송과 2009년 전국 실험방송을 거쳐 2010년 8월부터 본방송을 실시하는 등, DMB 재난경보방송 체계 마련을 위해 노력하여 왔다. 이러한 과정에서 차기 국가 모바일 재난경보 체계 마련의 필요성과 방향성에 대한 경험적 안을 제시해 본다. 본 연구는 급변하는 미디어 환경을 고려하여 모바일 재난 정보 전달체계에서 통신망의 역할을 강화하여 방송과 융합한 모델을 마련하고, 조속히 범국가적 재난정보의 표준 규격을 마련할 것을 촉구하며, 궁극적으로 뉴미디어 도입 정책에서 재난 정보전달에 관한 공공성 정책이 우선되어야 함을 제시하였다.
