An intelligent emergency system for hazard monitoring and building evacuation is a very important application area in Internet of Things (IoT) technology. Through the use of smart sensors, such a system can provide more vital and reliable information to first-responders and also reduce the incidents of false alarms. Several smart monitoring and warning systems do already exist, though they exhibit key weaknesses such as a limited monitoring coverage and security, which have not yet been sufficiently addressed. In this paper, we propose a monitoring and emergency response method for buildings by utilizing beacons and Unmanned Aerial Vehicles (UAVs) on an IoT security platform. In order to demonstrate the practicability of our method, we also implement a proof of concept prototype, which we call the UAV-EMOR (UAV-assisted Emergency Monitoring and Response) system. Our UAV-EMOR system provides the following novel features: (1) secure communications between UAVs, smart sensors, the control server and a smartphone app for security managers; (2) enhanced coordination between smart sensors and indoor/outdoor UAVs to expand real-time monitoring coverage; and (3) beacon-aided rescue and building evacuation.

The purpose of this study was to verify whether the type of national disaster management organization affects resilience capability and organizational effectiveness. In the present study, we analyzed a previous study conducted by Hollnagel on the inter-relationship between resilience capability and organizational effectiveness. Our results confirmed that public officers who are in charge of disaster management need to increase their resilience capability in order to improve organizational effectiveness. However, we cannot conclude that disaster management efficiency is improved only by increasing public officers' resilience capability. This study suggests that a dedicated organization for disaster management should be created to ensure effective handling of disasters. The influence of the type of organization should be considered, based on the results of this study.

This study examined the influence of Hollnagel 's resilience capability variables, which have recently been recognized worldwide, on the organizational effectiveness of national disaster management organizations. The components of organizational effectiveness were extracted from a previous research review, and 7 items for 4 capabilities were selected from 7 experts' Delphi survey analysis on Korean Resilience that included 56 items for 4 capabilities. Empirical analysis was conducted for the relationship between the resilience capability and organizational effectiveness, based on a questionnaire survey of 500 public officials in charge of disaster management. The analysis confirmed that the resilience proactive capability of public officials in charge of disaster management had the most significant effect on organizational effectiveness. In addition, the introduction of a dedicated organization and the improvement of the system have been suggested for strengthening the resilience capability of the organization members.
