    The numbers of natural disaster events are continuously affecting human and the world economics. For coping with disaster, several sectors try to develop the frameworks, systems, technologies and so on. However, there are little researches focusing on the usage behavior of Information Technology (IT) for disaster risk management (DRM). Therefore, this study investigates the affecting factors on the intention to use IT for mitigating disaster’s impacts. This study conducted a systematic review with the academic researches during 2011-2018. Two important factors from the Technology Acceptance Model (TAM) and others are used in describing individual behavior. In order to investigate the potential factors, the technology platforms are divided into nine types. According to the findings, computer software such as GIS applications are frequently used for simulation and spatial data analysis. Social media is preferred among the first choices during disaster events in order to communicate about situations and damages. Finally, we found five major potential factors which are Perceived Usefulness (PU), Perceived Ease of Use (PEOU), information accessibility, social influence, and disaster knowledge. Among them, the most essential one of using IT for disaster management is PU, while PEOU and information accessibility are more important in the web platforms

    This work aims at investigating and quantifying the Urban Transport System (UTS) resilience enhancement enabled by the adoption of emerging technology such as Internet of Everything (IoE) and the new trend of the Connected Community (CC). A conceptual extension of Functional Resonance Analysis Method (FRAM) and its formalization have been proposed and used to model UTS complexity. The scope is to identify the system functions and their interdependencies with a particular focus on those that have a relation and impact on people and communities. Network analysis techniques have been applied to the FRAM model to identify and estimate the most critical community-related functions. The notion of Variability Rate (VR) has been defined as the amount of output variability generated by an upstream function that can be tolerated/absorbed by a downstream function, without significantly increasing of its subsequent output variability. A fuzzy based quantification of the VR on expert judgment has been developed when quantitative data are not available. Our approach has been applied to a critical scenario (water bomb/flash flooding) considering two cases: when UTS has CC and IoE implemented or not. The results show a remarkable VR enhancement if CC and IoE are deploye

    Emergency alert and response is carried out in different ways around the world. Governments, corporate bodies and individuals take emergencies very seriously and continue to develop ingenious ways of responding to emergencies very swiftly. Most Urban areas have well-developed emergency response systems but this is not true of rural and sub-urban settlements. Security risk keeps increasing by the day due to rapid population growth. This is particularly true at the grassroots or community level. This paper proposes a very effective and economical way of alerting a community to all kinds of security emergencies. It incorporates the use of a mobile application that was codenamed “CEMAS” (Community Emergency Alarm System). The mobile application with a “Panic button” on it provides all inhabitants of the community with the means of triggering two SMS-activated central alarms. The first alarm is located at the community center and the second at the community police station. The central alarm system is activated by pressing the “Panic Button” whenever there is a security threat. The designed and implemented system worked satisfactorily well

    Several crises in many countries of the world are causing large migratory fluxes towards the most developed countries. The importance of migrants’ reception, acceptance and integration is increasing. The last phase of migration process concerns migrants’ integration, i.e. the process that start with migrants being accepted in the hosting country and end with migrants being completely integrated, i.e. autonomous both from an economic and a social point of view. Since this integration process is being slow and difficult, this research has two main objectives. The first one is to explore all the operations conducted by the organisations involved in the migrants’ integration process; the second one is to investigate about all the organisational factors that may have an impact on the integration process, with the purpose of improving it. Improving the integration process means being able to deliver services that are adequate to satisfy the migrants’ needs and expectations. With this exploratory purpose, two case studies have been conducted, in which two organisations involved in delivering services for migrants’ integration were analysed. At the end of the case studies analysis, a final framework was developed. It was found that the most important factors affecting the migrants’ integration are related to organisational capabilities, practices related to services co-design and co-creation, cooperative networks with other organisations and contextual factors like the social context in which they operate. The theoretical background about cooperative networks and operational improvement programs was crucial in order to identify these organisational factors that affect migrants’ integration

    Abstract This report considers the impact of anticipated climate change on Australia’s inland towns and centres to the year 2050. It examines the ways in which non-coastal settlements will be affected by the primary, secondary and tertiary impacts of climate change, including the impact of extreme climate events, a warming and drying climate over much of southern Australia and increased costs associated with both structural economic change and accelerated degradation of infrastructure. The research finds that climate change is likely to have a wide range of impacts on Australia’s system of inland settlement and that not all of these impacts are likely to be adverse. The published literature highlights the fact that some industries – including wool production, grains, viticulture and some grazing – are likely to benefit from climate change. While this is not the case in all instances, the fact that some industries will be enhanced runs contrary to both commonly held expectations and public discourse. In other sectors of the economy and society, technological change and/or investment in infrastructure will overcome many of the climate-change related challenges that have the potential to place the wellbeing of inland centres at risk. This project found that rural and regional centres across Australia will be affected by climate change in different ways, depending upon: Their industry structure; Their geographic location, especially their degree of remoteness; Their climatic conditions now and in the year 2030; and, The resource endowments of communities – and especially their stock of human, social, physical, fiscal and economic capital. The project reviewed the national and international literature on climate change adaptation to consider the vulnerability of individual inland centres. A vulnerability index was developed that was able to distinguish places that are more, and less, vulnerable to the negative impacts of climate change. This analysis was undertaken as a first step toward better understanding the differential impacts of climate change on the inland settlement system, and with a full awareness of the critiques of such approaches. The modelling highlighted that places that are remote confront some of the greatest risks from climate change, and that many – but not all – Indigenous communities are especially vulnerable. Detailed field work was undertaken in five case studies across Australia – Alice Springs, NT; Junee, NSW; Horsham, Victoria; Waikerie, South Australia; Moura, Queensland – in order to understand the steps taken by inland centres to plan and prepare for climate change. The research found that many persons within rural and regional communities do not accept that human-induced climate change is a reality, and that in consequence preparations for change are patchy. However, in many rural economies contemporary ‘good practice’ in farming or grazing is entirely consistent with the measures needed to plan for climate change. The fieldwork also highlighted the fact that while it is possible to model the potential impact of climate change, such measures overlook the commitment and willingness of groups to address this challenge. Finally, we conclude that climate change will contribute to the shifting nature of Australia’s inland settlement system to the year 2050 but that it will be just one of a number of factors contributing to change. Other factors, including global markets, demographic change, the relative prosperity of individual industries, and the investment decisions of government will be important also.

    Nowadays, rail transport has become one of the most widely utilised forms of transport thanks to its high safety level, large capacity, and cost-effectiveness. With the railway network's continuous development, including urban rail transit, one of the major areas of increasing attention and demand is ensuring safety or risk management in operation long-term remains for the whole life cycle by scientific tools, management of railway operation (Martani 2017), specifically in developed and developing countries like Vietnam. The situation in Vietnam demonstrates that the national mainline railway network has been built and operated entirely in a single narrow gauge (1000mm) since the previous century, with very few updates of manual operating technology. This significantly highlights that up to now, the conventional technique for managing the safety operation in general, and collision in particular, of the current Vietnamese railway system, including its subsystems, is only accident statistics which is not a scientific-based tool as the others like risk identify and analyse methods, risk mitigation…, that are already available in many countries. Accident management of Vietnam Railways is limited and responsible for accident statistics analysis to avoid and minimise the harm caused by phenomena that occur only after an accident. Statistical analysis of train accident case studies in Vietnam railway demonstrates that, because hazards and failures that could result in serious system occurrences (accidents and incidents) have not been identified, recorded, and evaluated to conduct safety-driven risk analysis using a well-suited assessment methodology, risk prevention and control cannot be achieved. Not only is it hard to forecast and avoid events, but it may also raise the chance and amount of danger, as well as the severity of the later effects. As a result, Vietnam's railway system has a high number of accidents and failure rates. For example, Vietnam Rail-ways' mainline network accounted for approximately 200 railway accidents in 2018, a 3% increase over the previous year, including 163 collisions between trains and road vehicles/persons, resulting in more than 100 fatalities and more than 150 casualties; 16 accidents, including almost derailments, the signal passed at danger… without fatality or casual-ty, but significant damage to rolling stock and track infrastructure (VR 2021). Focusing and developing a new standardised framework for safety management and availability of railway operation in Vietnam is required in view of the rapid development of rail urban transport in the country in recent years (VmoT 2016; VmoT 2018). UMRT Line HN2A in southwest Hanoi is the country's first elevated light rail transit line, which was completed and officially put into revenue service in November 2021. This greatly highlights that up to the current date, the UMRT Line HN2A is the first and only railway line in Vietnam with operational safety assessment launched for the first time and long-term remains for the whole life cycle. The fact that the UMRT Hanoi has a large capacity, more complicated rolling stock and infrastructure equipment, as well as a modern communica-tion-based train control (CBTC) signalling system and automatic train driving without the need for operator intervention (Lindqvist 2006), are all advantages. Developing a compatible and integrated safety management system (SMS) for adaption to the safety operating requirements of this UMRT is an important major point of concern, and this should be proven. In actuality, the system acceptance and safety certification phase for Metro Line HN2A prolonged up to 2.5 years owing to the identification of difficulties with noncompliance to safety requirements resulting from inadequate SMS documents and risk assessment. These faults and hazards have developed during the manufacturing and execution of the project; it is impossible to go back in time to correct them, and it is also impossible to ignore the project without assuming responsibility for its management. At the time of completion, the HN2A metro line will have required an expenditure of up to $868 million, thus it is vital to create measures to prevent system failure and assure passenger safety. This dissertation has reviewed the methods to solve the aforementioned challenges and presented a solution blueprint to attain the European standard level of system safety in three-phase as in the following: • Phase 1: applicable for lines that are currently in operation, such as Metro Line HN2A. Focused on operational and maintenance procedures, as well as a training plan for railway personnel, in order to enhance human performance. Complete and update the risk assessment framework for Metro Line HN2A. The dissertation's findings are described in these applications. • Phase 2: applicable for lines that are currently in construction and manufacturing, such as Metro Line HN3, Line HN2, HCMC Line 1 and Line 2. Continue refining and enhancing engineering management methods introduced during Phase 1. On the basis of the risk assessment by manufacturers (Line HN3, HCMC Line 2 with European manufacturers) and the risk assessment framework described in Chapter 4, a risk management plan for each line will be developed. Building Accident database for risk assessment research and development. • Phase 3: applicable for lines that are currently in planning. Enhance safety requirements and life-cycle management. Building a proactive Safety Culture step by step for the railway industry. This material is implemented gradually throughout all three phases, beginning with the creation of the concept and concluding with an improvement in the attitude of railway personnel on the HN2A line. In addition to this overview, Chapters 4 through Chapter 9 of the dissertation include particular solutions for Risk assessment, Vehicle and Infrastructure Maintenance methods, Inci-dent Management procedures, and Safety Culture installation. This document focuses on constructing a system safety concept for railway personnel, providing stringent and scientific management practises to assure proper engineering conditions, to manage effectively the metro line system, and ensuring passenger safety in Hanoi's metro operatio
