As metro systems are becoming more and more widely used, all kinds of emergencies happen from time to time. A series of cases indicate that inefficient emergency response is a dominating cause of tremendous casualties and losses. The fast and valid allocation of emergency resources after the occurrence of metro emergencies has become a key point in improving the sustainability of metro operations. However, few studies have attempted to determine the allocation of emergency resources in metro emergencies. In this study, considering the unpredictability of different emergency scenarios in the metro system, the scenario-response mode was applied in the resource allocation decision. In this mode, a metro emergency scenario framework was first constructed through the identification of metro emergency elements. Next, a multi-objective model was established for the allocation of emergency resources in the metro emergency rescue process using a scenario-based analysis. The model aims to minimize both the penalty costs due to delays and the sum of allocation costs. The particle swarm optimization algorithm was adopted to solve the model. Eventually, a fire accident scenario at Nanjing Metro was applied to verify the feasibility and validity of the presented model and algorithm. The research results not only enrich and improve metro emergency management theoretically, but also enhance metro emergency rescue ability in practice.

The emergency response capability of civil aviation airports is the core to ensure the efficient handling of civil aviation emergencies. The dynamic characterization of the multi-scenario evolution paths of emergencies in civil aviation airports and quantitative targeted evaluation have become the study foci urgently needed to be solved by the current academic circles and airport departments for emergency management. To clarify the emergency mechanism, evolution mechanism, and multi-scenario evolution paths, this study first constructed the pressure-state-response (PSR) network expression of emergency scenario evolution in civil aviation airports. Then, the evolution path of airport emergency scenarios and the probability of different evolution scenarios were evaluated on the basis of the PSR model and Bayesian network (BN). Lastly, the specific process of the analysis method for emergency scenarios based on PSR and BN was demonstrated in consideration of emergency rescue drills in civil aviation airports as example. Results show that different emergency response measures are adopted for the critical scenarios of emergencies, and the development and evolution paths of emergency scenarios completely differ. The PSR-BN model for emergency scenario analysis can realize the reasoning process of combining the qualitative and quantitative scenarios of the dynamic evolution of civil aviation emergencies. It can comprehensively and systematically analyse the evolution of emergency scenarios in civil aviation airports, prove the feasibility and effectiveness of the analysis method, and effectively compensate for the shortcomings in the static analysis of emergency events. The model provides reference for the emergency analysis of civil aviation airports.

The operation and maintenance of buildings has seen several advances in recent years. Multiple information and communication technology (ICT) solutions have been introduced to better manage building maintenance. However, maintenance practices in buildings remain less efficient and lead to significant energy waste. In this paper, a predictive maintenance framework based on machine learning techniques is proposed. This framework aims to provide guidelines to implement predictive maintenance for building installations. The framework is organised into five steps: data collection, data processing, model development, fault notification and model improvement. A sport facility was selected as a case study in this work to demonstrate the framework. Data were collected from different heating ventilation and air conditioning (HVAC) installations using Internet of Things (IoT) devices and a building automation system (BAS). Then, a deep learning model was used to predict failures. The case study showed the potential of this framework to predict failures. However, multiple obstacles and barriers were observed related to data availability and feedback collection. The overall results of this paper can help to provide guidelines for scientists and practitioners to implement predictive maintenance approaches in buildings.

Current Role

In this article, I review a cross-section of research in socio-hydrology from across disciplines in order to better understand the current role of historical-archival analysis in the development of socio-hydrological scholarship. I argue that despite its widespread use in environmental history, science and technology studies, anthropology, and human geography, archival methods are currently underutilized in socio-hydrological scholarship more broadly, particularly in the development of socio-hydrological models. Drawing on archival research conducted in relation to the socio-hydrology of coastal Guyana, I demonstrate the ways in which such scholarship can be readily incorporated into model development.

Fire Accident

Urban road tunnels are a reasonable remedy for inconvenience due to congested road traffic. However, they bring specific threats, especially those related to the possibility of fire outbreak. This work is a case study for selected urban road tunnels. Considering tunnel specificity, road traffic intensity, and structure and based on the literature data for vehicle fire probability, the chances of a fire accident were estimated for selected tunnels in Poland. It was shown that low power tunnel fires could be expected in the 10–20-year time horizon. Although such threats cannot be disregarded, tunnel systems are designed to cope with them. The chances of a disastrous fire accident were estimated as well. Such events can occur when an HGV with flammable goods or a tanker are involved. Such accidents are fortunately very rare, but, on the other hand, that is the reason why the available data are scanty and burdened with high uncertainty. Therefore, a discussion on the reliability of the obtained results is also provided.

The experiences from a case study are evaluated against the aspects such as emergency response to vulnerable populations and other sources from the literature to serve as guidelines for the management of an epidemic in a child and youth care centre (CYCC). To help understand the effects of the epidemic on the centre, this article describes experiences in terms of the meeting of needs. A discussion of the following are part of the article: • A reflection will be provided on the observed stages the children and child and youth care workers (CYCWs) went through during 177 days of a national lockdown; • Indications of caregiver burnout; • Experiences around the meeting of children’s needs through the lens of child and youth care (CYC) theory; and • Proposed areas needing attention in mitigating risks. Some lessons learnt from the daily routine established to manage the lockdown regulations, sometimes experienced as nonsensical, are shared. From these reflections, questions for research are provided from a practice-based evidence approach, mainly aimed at determining the readiness of a CYCC to manage a state of disaster, while needing to focus on meeting children’s needs.

Abstract As an emerging discipline, disaster nursing is very important in disaster emergency management, but there are few mature practice models and theoretical discussions. In particular, the contribution of nursing staff in disaster emergency has not yet received widespread attention and recognition. After more than ten years of rapid development, China’s disaster nursing has gradually formed a Chinese model and Chinese experience. During the global fight against COVID-19, this article takes the nursing work in disaster emergency rescue as the perspective and briefly describes the development process of disaster nursing in China to introduce the practice and theoretical development of disaster nursing in China to nursing workers around the world. By analyzing the role of Chinese nurses in national disaster emergency response, it provides a reference for global disaster nursing talent capacity building. By sharing the Nightingale spirit of Chinese nurses in disaster emergency, we will show people all over the world the professional value of disaster nursing practitioners and pay tribute to the nursing staff engaged in disaster emergency work.
