Prevenção, emancipação social e transição paradigmática: uma trajetória interdisciplinar de 40 anos no Brasil sobre acidentes e desastres / Prevención, emancipación social y transición paradigmática: una trayectoria interdisciplinaria de 40 años en Brasil sobre accidentes y desastres / Prevention, social emancipation, and paradigmatic transition: a 40-year interdisciplinary Brazilian trajectory on accidents and disasters

Resumo: O artigo, na forma de ensaio, sistematiza uma trajetória profissional de experiências interdisciplinares e socialmente engajadas em torno da análise e prevenção de acidentes e desastres nos últimos 40 anos. O trabalho acadêmico se desenvolveu principalmente no âmbito da pesquisa e pós-graduação na saúde pública brasileira impulsionado pelo movimento sanitarista e a construção do Sistema Único de Saúde (SUS) em sua busca por democracia, justiça social e sanitária. A base empírica envolveu ações de vigilância em saúde dos trabalhadores e ambiental organizadas em redes protagonizadas pelo SUS em conjunto com universidades, sindicatos, movimentos sociais, organizações não governamentais (ONG) ambientalistas e Ministérios Públicos. Eventos de maior complexidade socioambiental em setores como siderurgia, petroquímico, mineração, agronegócio e energia forjaram a busca por novos referenciais epistêmicos e interdisciplinares que abarcam duas novas justiças: a ambiental e a cognitiva. Este artigo apresenta essa trajetória de contribuições conceituais em três movimentos a partir da década de 1980 até os dias atuais, cada qual correspondendo a um contexto sociopolítico e institucional, para pensar movimentos de transição paradigmática na análise e prevenção de acidentes e desastres numa perspectiva interdisciplinar. Finaliza-se com a sugestão de prevenção abissal e emancipatória para enfrentar diferentes crises da atualidade, como a ambiental, a sanitária, a democrática e a civilizatória.

Abstract: The article, in the form of an essay, systematizes a 40-year-long professional trajectory of interdisciplinary and socially engaged experiences around the analysis and prevention of accidents and disasters. This study was mainly developed within the scope of research and postgraduate studies in Public Health in Brazil, driven by the sanitarian movement and the construction of Brazilian Unified National Health System (SUS) in its search for democracy and social and health justices. Its empirical basis involved workers' health and environmental surveillance actions organized in networks led by SUS in conjunction with universities, unions, social movements, environmental nongovernmental organizations (NGO), and Public Prosecutors' Offices. Events of greater socio-environmental complexity in sectors such as steel, petrochemicals, mining, agribusiness, and energy forged the search for new epistemic and interdisciplinary references that encompassed two new justices, i.e., environmental and cognitive. This essay systematizes this trajectory of conceptual contributions in three movements from the 1980s to the present day (each corresponding to a socio-political and institutional context) to reflect on paradigmatic transition movements in the analysis and prevention of accidents and disasters from an interdisciplinary perspective. It ends by suggesting abyssal and emancipatory prevention to face different current crises, including environmental, health, democratic, and civilizing ones.

Insights and viewpoints from a small-scale survey on current nuclear disaster preparedness measures in Japan after the Fukushima Daiichi Nuclear Power Plant accident.

In nuclear disaster prevention, it is essential not only to make daily efforts to prevent accidents from occurring but also to properly apply lessons learnt from actual disasters. Although significant changes have been made to nuclear disaster preparedness in Japan since the Fukushima Daiichi Nuclear Power Plant accident, there is insufficient information on whether these changes have been evaluated as practical and appropriate for the needs of the Japanese public. In this survey, 20 officials of the Cabinet Office and Japan Atomic Energy Agency, in charge of planning nuclear disaster prevention policy, were asked to evaluate the current nuclear disaster prevention plan through a questionnaire, and compare it with that before the accident, and indicate what elements are lacking in the current plan. The survey results revealed that 30% of the participants (six respondents) had a positive view of the enhancement of resources, including physical and human assets. However, as many as 60% (12 respondents) expressed negative sentiments, primarily due to perceived deficiencies in organisational measures, particularly the coordination of these resources. Moreover, the participants expressed keen interest in obtaining health data during evacuation, along with information on the physical and mental effects on evacuees living in evacuation centres. These crucial insights can inform the formulation of effective future preparedness plans for evacuation and radiation protection.

Urban rainstorm and waterlogging scenario simulation based on SWMM under changing environment.

Urban rainstorm and waterlogging occurred more frequently in recent years, causing huge economic losses and serious social harms. Accurate rainstorm and waterlogging simulation is of significant value for disaster prevention and mitigation. This paper proposed a numerical model for urban rainstorm and waterlogging based on the Storm Water Management Model (SWMM) and Geographic Information System (GIS), and the model was applied in Lianhu district of Xi'an city of China. Furthermore, the effects of rainfall characteristics, pipe network implementation level and urbanization level on waterlogging were explored from the perspectives of spatial distribution of waterlogging points, drainage capacity of pipe network and surface runoff generation and confluence. The results show that: (1) with the increase of rainfall recurrence period, the peak of total water accumulating volume, the average decline rate of water accumulating volume and the number of waterlogging nodes increase; (2) optimizing the pipe diameter can shorten the average overload time of the pipe network from the entire pipe network, but for a single pipe, optimizing the pipe diameter may lead to overloading of unoptimized downstream pipeline; (3) the lower the imperviousness, the less the number of waterlogging nodes and average time of water accumulating, and (4) the west, northwest and southwest areas are relatively affected by the imperviousness, only improving the underlying surface conditions has limited influence on waterlogging in the study area. This study can provide reference for urban waterlogging prevention and reduction and pipe network reconstruction.

Design and evaluation of radiation disaster prevention map based on evacuation behavior.

An effective disaster prevention map ensures public safety and efficient evacuation during emergencies. Emergency evacuation information design in Taiwan is in its nascent stages. This study focuses on individuals' understanding, behavior, and decision-making during disaster prevention to devise suitable disaster prevention map norms. We examined the Emergency Planning Zone's existing disaster prevention methods and surveyed the community to understand their disaster prevention concepts and needs. We conducted two experiments: the first tested the comprehension of existing disaster prevention maps and identified their issues, while the second evaluated a redesigned map based on Experiment 1's findings. We discovered that all age groups agree on needing accurate, fast information and diverse evacuation route options. Experiment 1 revealed disproportionate assembly point icons on the existing map, leading to navigation difficulties. The map also failed to mark landmarks, road names, and blocked intersections accurately. The redesigned map in Experiment 2 addressed these issues, showing that improving map information design aids recognition and memory, and bridges wayfinding behavior gaps in people with different spatial abilities. We suggest marking evacuation routes on maps, placing corresponding signs on-site, and locating assembly points near landmarks for easier navigation.

Potato Ethics: What Rural Communities Can Teach Us about Healthcare.

In this paper I offer the term "potato ethics" to describe a particular professional rural health sensibility. I contrast this attitude with the sensibility behind urban professional ethics, which often focus on the narrow doctor-patient treatment relationship. The phrase appropriates a Swedish metaphor, the image of the potato as a humble side dish: plain, useful, versatile, and compatible with any main course. Potato ethics involves making oneself useful, being pragmatic, choosing to be like an invisible elf who prevents discontinuity rather than a more visible observer of formal rules and assigned tasks. It also includes actively taking part in everyday disaster-prevention and fully recognizing the rural context as a vulnerable space. This intersectional argument, which emphasizes the ongoing, holistic responsibility of those involved in rural communities, draws on work from the domains of care ethics, relational ethics, pragmatic psychology, feminist ethics of embodiment, social location theory, and reflections on geographical narcissism.

Identifying Evacuation Needs and Resources Based on Volunteered Geographic Information: A Case of the Rainstorm in July 2021, Zhengzhou, China.

Recently, global climate change has led to a high incidence of extreme weather and natural disasters. How to reduce its impact has become an important topic. However, the studies that both consider the disaster's real-time geographic information and environmental factors in severe rainstorms are still not enough. Volunteered geographic information (VGI) data that was generated during disasters offered possibilities for improving the emergency management abilities of decision-makers and the disaster self-rescue abilities of citizens. Through the case study of the extreme rainstorm disaster in Zhengzhou, China, in July 2021, this paper used machine learning to study VGI issued by residents. The vulnerable people and their demands were identified based on the SOS messages. The importance of various indicators was analyzed by combining open data from socio-economic and built-up environment elements. Potential safe areas with shelter resources in five administrative districts in the disaster-prone central area of Zhengzhou were identified based on these data. This study found that VGI can be a reliable data source for future disaster research. The characteristics of rainstorm hazards were concluded from the perspective of affected people and environmental indicators. The policy recommendations for disaster prevention in the context of public participation were also proposed.

Does the eight-factor "power to live" in disaster exist since childhood?

Background: Studies on the survivors of the 2011 Great East Japan earthquake and tsunami have revealed eight factors, called power to live, which are closely related to resilience and effective coping after intense and prolonged stress. However, whether the eight factors, which were examined in adults, are applicable to children is unclear. The purpose of this study is to evaluate whether the eight-factor structure of power to live was present since late childhood. Method: A 34-item power to live questionnaire was filled by middle- to upper-grade elementary (n = 378) and junior high school students (n = 456). Moreover, because elementary school students may lack introspective ability, their power to live was evaluated through a parental assessment (n = 358). Additionally, we examined the relationship between each power to live factor and questions regarding disaster prevention awareness among 25 elementary school students. Results: The results from confirmatory factor analysis for factor structure revealed generally acceptable fit indices. The reports from elementary school students and their parents significantly positively correlated with each power to live factor. Although reliability indices for factors such as stubbornness, etiquette, self-transcendence, and active well-being were not good for elementary school students, the reliability indices for all factors, excluding stubbornness, increased in junior high school students. Moreover, we identified a correlation between problem-solving, altruism, and emotional regulation and questionnaire items regarding awareness of disaster prevention in elementary school students. Conclusion: Our results suggest that although factors common to adults, such as leadership, problem-solving, altruism, and emotional regulation, were identified at the elementary school stage, some factors, such as stubbornness, are in the process of being formed. Future studies should examine the developmental changes assumed to underlie these factors and their relationship to experience and neurodevelopmental basis.

Factors Associated with Housing Damage Caused by an EF4 Tornado in Rural Areas of Funing, China.

Rural areas are vulnerable to natural disasters and tend to suffer severe losses. An EF4 tornado occurred in Funing on 23 June 2016, killing 99 people, injuring at least 846 people, and destroying more than 2000 houses. Using a multinomial logistic regression model, this study explored the influencing factors between housing damage and variables of building conditions, tornado intensity, and village environmental factors. The results show that 2-story houses and masonry houses were more likely to be slightly damaged or be in a dangerous state. Furthermore, the building area was positively related to houses in two categories: slight damage (SD) and dangerous and requiring immediate repair (DR), indicating that the larger or taller the house, the more severe the damage. In terms of tornado intensity, houses classified as SD were more likely to be hit by EF4 tornados than by EF3 tornados, and houses were damaged more by EF1 or EF2 tornados. This finding demonstrates that the level of housing damage was not strongly correlated with the tornado intensity. Slightly damaged houses exhibited the highest correlation with environmental factors. The proportion of slightly damaged houses was positively correlated with the water area in the village, unlike the proportion of houses in the DR and unable to be repaired (UR) categories. Moreover, the larger the water area of a village, the less housing damage it suffered. These findings provide new insights into minimizing housing damage in wind disasters to improve disaster prevention planning in rural areas.

Comparative Study on International Research Hotspots and National-Level Policy Keywords of Dynamic Disaster Monitoring and Early Warning in China (2000-2021).

For more than 20 years, disaster dynamic monitoring and early warning have achieved orderly and sustainable development in China, forming a systematic academic research system and top-down policy design, which are inseparable from the research of China's scientific community and the promotion of government departments. In the past, most of the research on dynamic disaster monitoring and early warning focused on specific research in a certain field, scene, and discipline, while a few studies focused on research review or policy analysis, and few studies combined macro and meso research reviews in academia with national policy analysis for comparative analysis. It is necessary and urgent to explore the interaction between scholars' research and policy deployment, which can bring theoretical contributions and policy references to the top-down design, implementation promotion, and academic research of China's dynamic disaster monitoring and early warning. Based on 608 international research articles on dynamic disaster monitoring and early warning published by Chinese scholars from 2000-2021 and 187 national policy documents published during this period, this paper conducts a comparative analysis between the knowledge maps of international research hotspots and the co-occurrence maps of policy keywords on dynamic disaster monitoring and early warning. The research shows that in the stage of initial development (2000-2007), international research articles are few and focused, and research hotspots are somewhat alienated from policy keywords. In the stage of rising development (2008-2015), after the Wenchuan earthquake, research hotspots are closely related to policy keywords, mainly in the fields of geology, engineering disasters, meteorological disasters, natural disasters, etc. Meanwhile, research hotspots also focus on cutting-edge technologies and theories, while national-level policy keywords focus more on overall governance and macro promotion, but the two are gradually closely integrated. In the stage of rapid development (2016-2021), with the continuous attention and policy promotion of the national government, the establishment of the Ministry of Emergency Management, and the gradual establishment and improvement of the disaster early warning and monitoring system, research hotspots and policy keywords are integrated and overlapped with each other, realizing the organic linkage and mutual promotion between academic research and political deployment. The motivation, innovation, integration, and transformation of dynamic disaster monitoring and early warning are promoted by both policy and academic research. The institutions that issue policies at the national level include the State Council and relevant departments, the Ministry of Emergency Management, the Ministry of Water Resources, and other national ministries and commissions. The leading affiliated institutions of scholars' international research include China University of Mining and Technology, Chinese Academy of Sciences, Wuhan University, Shandong University of Science and Technology, and other institutions. The disciplines involved are mainly multidisciplinary geosciences, environmental sciences, electrical and electronic engineering, remote sensing, etc. It is worth noting that in the past two to three years, research and policies focusing on COVID-19, public health, epidemic prevention, environmental governance, and emergency management have gradually increased.

Factors Associated with Knowledge of Evacuation Routes and Having an Emergency Backpack in Individuals Affected by a Major Earthquake in Piura, Peru.

Information on the prevention of earthquakes in Peru, a high-risk country, is still emerging. We determined the frequency and factors associated with knowledge of evacuation routes and the use of emergency backpacks in people affected by a major earthquake. A cross-sectional study using secondary data was conducted from August-December 2021 on people that experienced the 6.1 magnitude earthquake that occurred in Piura, Peru on 30 July 2021. The outcome was self-reported knowledge of evacuation routes and the use of emergency backpacks. The association with self-reported earthquake preparation training, use of sources of information on earthquakes, and sociodemographic variables was investigated. A total of 69.5% of participants knew evacuation routes, and 46.3% had an emergency backpack. A higher frequency of knowledge of evacuation routes was associated with previous training (PR: 1.47; 95% CI: 1.15-1.87), use of the media (PR: 1.35; 95% CI: 1.06-1.72), having received information from the COEN (PR: 1.19; 95% CI: 1.02-1.40), and with a greater number of household members (PR: 1.03; 95% CI: 1.01-1.06). There is a high frequency of knowledge of evacuation routes among participants. However, basic notions of prevention culture are still needed. This research contributes to policy development on earthquake preparation at the community level.

Disaster risk management system in Vietnam: progress and challenges.

Background: Vietnam is one of the countries most impacted by disasters in Asia- Pacific. Floods, droughts and storms are the most common catastrophes. These risks endanger millions of lives and create massive financial and production losses. Objective: This study aims at reviewing the disaster risk management (DRM) system in Vietnam, identifying progress and challenges of this system, hence making recommendations for improving the system for better responding with natural hazards. Method: The study uses PSR model (Pressure- State- Response) in combination with DRM management framework by United Nations Development Program (UNDP) to evaluate DRM system in Vietnam with 5 aspects: (i) DRM regulatory framework (ii) DRM organization (iii) DRM financial resources (iv) DRM integration in to plans at central and local levels (v) Disaster warning and education. The data collection consists of reviewing existing literature and interviewing key informants in DRM. Results: Disasters is a serious threat to Vietnam's socio economic development. To respond, Vietnam has made many efforts including develop a comprehensive legal framework for DRM which Law on Disaster Prevention and Control takes the key role. Vietnam has also established a fairly well organized DRM system from the central to local levels. The financial sources for DRM are arranged from State budget and sources outside State budget. Vietnam has developed major policies for integrating DRM into development plans centrally and locally. The disaster information and warning system is being modernized with the integration of disaster education in training programs. Challenges in DRM are identified, including institutional, financial and information issues. In addition, Vietnam is facing the increase of disasters and extreme climate events due to climate change. Covid 19 and its socio-economic consequences also lead to a lack of resources for DRM. Economic development moreover results in the decline of ecosystem-based disaster mitigation works and put more pressures on DRM. Recommendations: In the future, Vietnam should develop an information-sharing network between ministries, sectors, localities and NGOs to support the policy formulation process and enhance the coordination of multi-stakeholders. The country should also establish more proper funding allocation mechanisms to fulfill DRM's demands, especially for disaster preparedness and reconstruction phases.

Factors Influencing Public Participation in Community Disaster Mitigation Activities: A Comparison of Model and Nonmodel Disaster Mitigation Communities.

Public participation in community-organized disaster mitigation activities is important for improving disaster mitigation capacity. With data from 260 questionnaires, this study compared the current status of public participation in model disaster mitigation communities and nonmodel communities in a geological-disaster-prone area. Three community-organized disaster mitigation education activities were compared cross-sectionally. A binary logistic regression was used to analyze the effects of attitude, perceived behavioral control, disaster experience, and other key factors on the public's choice to participate in community disaster mitigation activities. The analysis results indicated that model communities had higher public participation in two efforts, evacuation drills and self-help skills training, and lower participation in activities that invited them to express their feedback than nonmodel communities. The influence of attitudinal factors on the decision to participate in disaster mitigation activities had a high similarity across community types. The public participation in model disaster mitigation communities is influenced by factors such as subjective norms and participation cognition; the behavior of people in nonmodel communities is influenced by factors such as previous experience with disasters, perceived behavioral control, risk perception, and participation cognition and has a greater potential for disaster mitigation community construction. This study provides practical evidence and theoretical support for strengthening the sustainable development of disaster mitigation community building.

Construction and Evaluation of a Safe Community Evaluation Index System-A Study of Urban China.

A community is the basic unit of a city. Scientific and effective evaluations of the construction effect of safe communities can improve the construction capacity of community disaster prevention and mitigation; it is also the basis for improving urban public safety and realizing stable and sustainable urban operation. First, following the development framework of a safe community and taking two typical communities in Xi'an, China, as examples, based on the literature and expert opinions, the initial indicators of a safe community are determined. Second, based on existing data, the literature and expert opinions, a questionnaire is designed, and the reliability and validity of the questionnaire are tested by exploratory factor analysis. Third, the indicators for evaluating the construction ability of a safe community are selected. Finally, an evaluation model of the construction ability of safe communities is constructed by using the comprehensive weighting technique for order of preference by similarity to the ideal solution (TOPSIS), which is applied to the actual evaluation of eighteen representative communities in Xi'an. The main findings are as follows. (1) The sense of community security is the collective consciousness of community residents. It includes not only the security and feelings of community residents themselves, but also the cognition of the impact of social policies at the macro and micro-levels on community residents, their families, and even the whole community. (2) From the three levels of consciousness, technology, and policy as the starting points for the construction of the theoretical model of a safe community, organizational resilience, accessibility resilience, social environmental resilience, and capital resilience are found to be the main influencing factors in the construction of a safe community. (3) Using questionnaires and expert interviews to preliminarily screen evaluation indicators and using the comprehensive weighting TOPSIS method to build an evaluation model can effectively avoid the defects of traditional empirical research on the validity and reliability of methods. (4) The ranking of the eighteen representative communities in the empirical analysis is basically consistent with the selection results of the national comprehensive disaster reduction demonstration community, which indicates the effectiveness and accuracy of the indicators and algorithms.

Sustainable Earthquake Resilience with the Versatile Shape Memory Alloy (SMA)-Based Superelasticity-Assisted Slider.

Earthquakes threaten humanity globally in complex ways that mainly include various socioeconomic consequences of life and property losses. Resilience against seismic risks is of high importance in the modern world and needs to be sustainable. Sustainable earthquake resilience (SER) from the perspective of structural engineering means equipping the built environment with appropriate aseismic systems. Shape memory alloys (SMAs) are a class of advanced materials well suited for fulfilling the SER demand of the built environment. This article explores how this capability can be realized by the innovative SMA-based superelasticity-assisted slider (SSS), recently proposed for next-generation seismic protection of structures. The versatility of SSS is first discussed as a critical advantage for an effective SER. Alternative configurations and implementation styles of the system are presented, and other advantageous features of this high-tech isolation system (IS) are studied. Results of shaking table experiments, focused on investigating the expected usefulness of SSS for seismic protection in hospitals and conducted at the structural earthquake engineering laboratory of the University of Bonab, are then reported. SSS is compared with currently used ISs, and it is shown that SSS provides the required SER for the built environments and outperforms other ISs by benefitting from the pioneered utilization of SMAs in a novel approach.

Percepción del riesgo de desastres en habitantes del municipio de Pijao, Quindío, Colombia / Perception of Disaster Risk Among Inhabitants of the Municipality of Pijao, Quindío, Colombia

Resumen La gestión del riesgo de desastres es un proceso social, por ello toda la comunidad debe estar incluida en ella. El objetivo del estudio fue analizar las percepciones del riesgo de desastres en habitantes del municipio de Pijao (Quindio). Para esto se siguió un enfoque cualitativo desde el diseño de la teoría fundamentada. Se realizó un muestreo no probabilístico en los barrios aledaños al recorrido del Río Lejos del municipio de Pijao (Quindío, Colombia). La muestra estuvo compuesta por un total de 60 sujetos. La teoría sustantiva producto de la investigación es la naturalización de la gestión del riesgo de desastres. Se considera que la naturalización de acciones para la mitigación del riesgo de desastres se posibilita por el nivel de conocimiento de conceptos y acciones de la gestión del riesgo, además del nivel de arraigo cultural. El estudio permitió conocer de primera mano sobre los elementos que se deben trabajar para fortalecer la gestión del riesgo a nivel comunitario.

Abstract Disaster risk management is a social process; therefore, the whole community must be included in it. The objective of the study was to analyze the perceptions of disaster risk in the inhabitants of the municipality of Pijao (Quindio). A qualitative approach was followed from the design of the grounded theory. A non‑probabilistic sampling was carried out in the neighborhoods adjacent to the course of the Lejos River in the municipality of Pijao (Quindio, Colombia). The sample was composed of a total of 60 subjects. The substantive theory resulting from the research is the naturalization of disaster risk management. It is considered that the naturalization of actions for disaster risk mitigation is made possible by the level of knowledge of risk management concepts and actions, in addition to the level of cultural rootedness. The study provided first-hand knowledge of which elements level should be worked on in the community to strengthen risk management.

[Public health nurses' activities during normal times and factors associated with their promotion of residents' mutual support during disasters].

Objective　To clarify the actual state of activities conducted by public health nurses (PHNs) during normal times and assess factors related to the implementation of such activities for the promotion of residents' mutual support during disasters, across different municipalities in Japan.Methods　We conducted a nationwide cross-sectional self-report questionnaire survey of PHNs in 1,463 municipalities. The questionnaires included descriptions of municipalities, activities related to disaster prevention and the rationale for them, and the details of activities that were being conducted to promote residents' mutual support in times of disaster. We conducted multiple logistic analyses to examine the associated factors.Results　We analyzed 535 responses (valid response rate of 36.6%). The proportion of municipalities in which oriented district activity systems and oriented business activity systems were used jointly by PHNs was 81.7%. The proportion of municipalities in which PHNs participated in the formulation of regional disaster prevention plans was 31.6%. "Individual support" would be implemented for persons requiring support in evacuation activities in 41.7% of municipalities; "cooperative support for community organizations," in 34.8%; and other "activities for the purpose of residents' mutual support," in 29.9%. Reasons for not implementing such measures included "outside the division of duties" and "having no contact with residents' organizations." Logistic regression analyses showed that the oriented district activity system, participation of PHNs in the formulation of regional disaster prevention plans, and preparation of an activity manual on disaster countermeasures for PHNs were significantly associated with the performance of activities during normal times for promotion of residents' mutual support during disasters.Conclusion　Our findings clarified that the PHNs' activities during normal times for the promotion of residents' mutual support during disasters were not carried out sufficiently. It is important to review activities according to the district, to ensure supervisory PHNs play a greater role, to provide external support to municipalities for the participation of PHNs in the formulation of regional disaster prevention plans, and to prepare an activity manual on disaster countermeasures for PHNs.

[Management and impact of interventions to reduce COVID-19 cases in Costa RicaGestão e impacto das medidas de intervenção para reduzir os casos de COVID-19 na Costa Rica]. / Gestión e impacto de las medidas de intervención para la reducción de casos por COVID-19 en Costa Rica.

Objective: Assess the impact of interventions introduced in Costa Rica during 2020 and 2021 to control the COVID-19 pandemic. Methods: A Bayesian Poisson regression model was used, incorporating control or intervention measures as independent variables in the changes in reported case numbers per epidemiological week. Results: The results showed the relative and combined impact of containment policies and measures on the reduction of cases: mainly vehicular traffic restrictions, use of masks, and implementation of health guidelines and protocols. Evidence of impact was optimized and made available for decision-making by the country's health and emergency authorities. Several iterations were generated for constant monitoring of variations in impact at four different moments in the pandemic's spread. Conclusion: The simultaneous implementation of different mitigation measures in Costa Rica has been a driving force in reducing the number of COVID-19 cases.

Objetivo: Avaliar o impacto das intervenções realizadas na Costa Rica durante 2020 e 2021 para o controle da pandemia de COVID-19. Método: Foi utilizado um modelo Bayesiano de regressão de Poisson que incorporou as medidas de controle ou intervenção como variáveis independentes sobre a variação do número de casos por semana epidemiológica. Resultados: Os resultados evidenciaram o efeito relativo e conjunto que as políticas ou medidas de contenção tiveram na redução de casos, principalmente as restrições a veículos, o uso de máscaras e a implementação de diretrizes e protocolos de saúde. As evidências dos efeitos foram otimizadas e disponibilizadas às autoridades sanitárias e de emergência do país para auxiliar na tomada de decisão. Diversas iterações foram geradas para o monitoramento constante da variação nos efeitos em quatro momentos distintos do avanço da pandemia. Conclusão: A aplicação simultânea de diferentes medidas de mitigação na Costa Rica tem sido um agente promotor da diminuição de casos de COVID-19.

Simulation and Optimization Strategy of Storm Flood Safety Pattern Based on SCS-CN Model.

The contradiction between rapid urbanization's demand for land resources and the ecological environment is increasing, which has led to large-scale hardening of the underlying surface of the city and reduction of land for storage. In addition, construction land occupies rainwater confluence land, resulting in a significant decline in urban stormwater control capabilities. The increasingly frequent flood disasters in recent years have exposed the contradiction between urban construction and stormwater safety that cannot be ignored. Therefore, this article takes the central city of Harbin as the research object, uses ArcGIS for spatial analysis and SCS (Soil Conservation Service) hydrological model simulation to construct the rain and flood safety pattern in the research area, and proposes targeted optimization suggestions and strategies based on the evaluation results to achieve the purpose of coordinating the water ecosystem service function with social and economic development. The research shows that protecting the original stormwater corridor and strengthening the connection between the stormwater control patches can effectively guarantee the connectivity of the stormwater corridor, build the natural stormwater regulation and storage system, and then increase the ability of the city to resist the risk of rainstorm, reduce the disaster caused by urban waterlogging, and achieve the goal of sponge city construction.

Research on the Safety and Security Distance of Above-Ground Liquefied Gas Storage Tanks and Dispensers.

Many countries lack clear legal requirements on the distance between buildings and petrol station facilities. The regulations in force directly determine the petrol station facilities' required distance to buildings, and such distances are considered relevant for newly designed and reconstructed buildings. Public buildings must be located no closer than 60 m to the above-ground liquefied gas tanks and liquid gas dispensers. Still, based on engineering calculations and the applied technical measures, it is possible to determine a safe distance for buildings that are constructed, extended and reconstructed, to which superstructures are added or whose utilisation method changes. The paper presents the results of calculations devoted to determining a safe distance between public buildings and LPG filling station facilities, using selected analytical models. The analyses were carried out for the LPG gas system commonly used in petrol stations, consisting of two gas storage tanks of 4.85 m3 capacity each, and a dispenser. It is legitimate to eliminate the obligation to observe the 60 m distance between LPG filling stations and public buildings and the mandatory distance of 60 m between liquefied gas dispensers and public buildings is not justified in light of the implemented requirements to use various protections at self-service liquefied gas filling stands.

Chain of Survival in Industrial Emergencies and Industrial Disasters.

The Chain of Survival in Industrial Emergencies and Disasters is similar to the cardiac arrest chain of survival of the American Heart Association (AHA) and the trauma chain of survival. It is a sequence of five inter-linked rings, which when practiced, decreases the mortality and morbidity in the concerned population. The first ring is Early Prevention, which should be a combined effort of healthcare professionals and industrial authorities. The second ring is Early Recognition. Industrial workers and surrounding communities should be equally trained in hazard and risk analysis along with vulnerability assessment. The third ring is Access to Care by the Early Response System, involving a universal emergency response number and early intervention by on-site trained medical professionals. This ring emphasizes the importance of a link with the surrounding communities, as they are the first responders and the front-line victims. The fourth ring is Early Advanced Care by EMS for transportation to hospitals or by Emergency Department personnel in referral hospitals. The fifth and the last ring is Early Rehabilitation, which includes integrated post emergency care, overall rehabilitation and early return to work. The key to successful implementation of Chain of Survival is to have identified components of care, training and quality monitoring. When practiced diligently, this could help prevent industrial disasters, and mitigate their harmful effects on occurrence.
