“…Many of these have already created dedicated strategies and plans in this direction. For example, the UK has developed the Government Transformation Strategy 2017-2020 [ 101 ], which endeavors to give directions to a full scale governmental digital transformation. Similarly, other governments around the world are working diligently to change their strategic and operational dynamics and priorities to cope with the new digital era [ 102 ].…”

With the increasing social and economic devastation caused by disasters around the world, the international community and country-level National Disaster Management (NDM) authorities have placed improving their ways to mitigate, prepare for, respond to, and recover from disasters as a top priority. Technological advancements and the 4th Industrial Revolution are critical tools to help achieve this. However, they also present many challenges to traditional NDM systems by altering the fundamental operational, organizational, and social dynamics of conventional disaster management. Currently, there is a lack of research that studies these aspects beyond technology and examines the impact of digital transformation on the full life cycle of disaster management on the national level. Therefore, this research fills this gap by integrating interdisciplinary concepts from different research fields including Disaster Management, Information Systems, and Business Management to understand the impact and determinants of digital transformation in NDM systems. To achieve this, the research uses the Technology-Organization-Environment (TOE) framework and conducts semi-structured interviews with UK NDM experts. The results show that the impact of digital transformation on NDM is profound, paradoxical, multi-directional, and driven by a multitude of driving forces. This research makes many significant contributions to research and practice. Theoretically, this research expands the TOE framework beyond its original underpinnings by uncovering a new set of disaster-context determinants. It also presents an innovative Layered Cake FAST (Foundations-Approach-Strategy-Technology) Model that offers a unique roadmap for NDM on how to handle its digital transformation journey. Practically, the research presents several sets of useful expert-recommended actions.

“…It is worth noting that the presence of malicious nodes in emergency networks in a post-disaster period is not a rare event [35], [36] and counteracting them is particularly demanding. Among the broad spectrum of possible issues, Denial of Service (DoS) attacks are considered extremely dangerous, and their prevention is of pivotal importance.…”

“…Within the context of emergency networks, DoS attacks are considered extremely dangerous, since they are easy to implement and capable of severe damages to the network by making certain key nodes unavailable. Therefore, protection against them is of pivotal importance [36]. In this section, we provide an overview of the main solutions for DoS protection for gossiping.…”

“…In particular, as investigated in this paper, a scheme called gossiping (a distributed scheme of message dissemination where multiple copies of information are forwarded towards the destination via multiple paths) is considered as a proper solution in many disaster scenarios. However, as gossiping exhibits vulnerabilities which can be exploited in further attacks (or to compromise the end-user applications built on top of gossiping), and since the presence of malicious nodes in a post-disaster period is not a rare event [35], [36], a proper functioning of gossiping still requires certain adjustments.…”

Based on real-time AR technology, this paper processes high-resolution graphics and uses it in graphic design. A high-resolution image equalization algorithm based on the maximum entropy model is proposed. First, use the Otsu method to determine the data segmentation point of high-resolution graphics; then preprocess the high-resolution image; then traverse according to the proposed maximum entropy model to find the dynamic range segmentation point that maximizes the image entropy after equalization, and finally according to the data segmentation point and dynamics, the range division point performs highresolution image equalization on the image to obtain the final enhancement result. Experiments show that compared with other comparison algorithms, the algorithm has a wide application range, strong detail retention ability, and natural effect. Experiments show that compared with other contrast algorithms, this algorithm has a proper contrast improvement, a wide range of applications, can be used for real-time video enhancement and graphic design and is practical. In the graphic design stage, the involvement of digital technology has become a basis for designers to choose horizontal solutions. In the early stage site design and mid-term graphics selection, the performance analysis software in BIM was used to analyze the acousto-optic heat of the plane. Based on this intuitive data analysis, the scheme was weighed. At the same time, the VR three-dimensional space experience reinforces the "people-oriented" design principle. With the help of digital technology, the designer compares the solutions horizontally from the perspective of rationality and sensibility, to choose the sustainable design of graphic design. INDEX TERMS Real-time AR technology; high-resolution images; graphic processing; graphic design.
