The aim of this study was to assess acceptance COVID-19 vaccination and the willingness pay (WTP) for it, investigate associated factors among pregnant women in Vietnam.
Mobile devices with embedded sensors for data collection and environmental sensing create a basis cost-effective approach trading. For example, these can be related to pollution gas emissions, which used check the compliance national international regulations. The current IoT trading relies on centralized third-party entity negotiate between consumers providers, is inefficient insecure large scale. In comparison, decentralized based distributed ledger technologies (DLT) enables while...
The pervasive need to safely share and store information between devices calls for the replacement of centralized trust architectures with decentralized ones. DLTs are seen as most promising enabler trust, but they still lack technological maturity, their successful adoption depends on understanding fundamental design trade-offs reflection in actual technical design. This work focuses challenges potential solutions an effective integration context Internet Things (IoT). We first introduce...
Blockchain has recently been depicted as a secure protocol for information exchange in cyber-physical microgrids. However, it is still found vulnerable to consensus manipulation attacks. These stealth attacks are often difficult detect they use kernel-level access mask their actions. In this paper, we firstly build trusted and secured peer-to-peer network mechanism physical DC microgrids' validation of transactions over Distributed Ledger. Secondly, leverage from physics-informed approach...
In a Federated Learning (FL) setup, number of devices contribute to the training common model. We present method for selecting that provide updates in order achieve improved generalization, fast convergence, and better device-level performance. formulate min-max optimization problem decompose it into primal-dual where duality gap is used quantify Our strategy combines \emph{exploration} data freshness through random device selection with \emph{exploitation} simplified estimates...
The data collected from IoT devices on various emissions or pollution can have significant economic value for stakeholders. This makes it prone to abuse tampering and brings forward the need integrate with a DLT collect, store, protect data. However, additional overhead frugal connectivity symmetrizes traffic, thus changing usual assumption that is uplink-oriented. We implemented platform integrates DLTs monitoring system based NB-IoT. evaluate performance discuss trade-offs in two use...
Abstract Objectives To establish our first Infection Summit, aiming to engage and educate non-infection specialists locally improve antimicrobial stewardship (AMS) identify quality improvement (QI) ideas AMS interventions, through collaboration. also gather feedback determine any benefits of this trust-wide event. Methods LTHT did not meet the NHS standard contract targets for consumption in 2023–24 so Summit was created implemented. A wide variety healthcare professionals from 14 different...
This study aimed to examine fear of childbirth and willingness pay for fear-prevention services in pregnant women. A multicenter, cross-sectional was conducted on women two obstetric hospitals Vietnam. The Fear Birth Scale utilized evaluate childbirth. Multivariable, generalized linear regression logistic models were performed identify associated factors with childbirth, demand, prevention services. Of 900 women, moderately high a mean score 18.1 (SD = 2.3). Age partner; ever having...
In recent years, industrial manufacturing has undergone massive technological changes that embrace digitalization and automation towards the vision of intelligent plants. With aim maximizing efficiency profitability in production, an important goal is to enable flexible manufacturing, both, for customer (desiring more individualized products) manufacturer (to adjust market demands). Manufacturing-as-a-service can support this through plants are used by different tenants who utilize machines...
Abstract Background Self-care behaviors during pregnancy significantly impacts mother and children's health. This study aimed to explore the self-care associations of these with psychological well-being women pregnancy, as well mediating effects different social support associations. Methods A cross-sectional data 562 pregnant at Hanoi Obstetrics & Gynecology Hospital Ca Mau Pediatrics in Vietnam were analyzed. Questions about behaviors, characteristics, support, asked. Multivariate...
Decentralized Autonomous Organization (DAO) is an organization constructed by automatically executed rules such as via smart contracts, holding features of the permissionless committee, transparent proposals, and fair contribution stakeholders. As Nov 2022, DAO has impacted over \$11.2B market caps. However, there are no substantial studies focused on this emerging field. To fill gap, we start from ground truth empirically studying breadth depth markets in mainstream public chain ecosystems...
Various data-sharing platforms have emerged with the growing public demand for open data and legislation mandating certain to remain open. Most of these opaque, leading many questions about accuracy, provenance lineage, privacy implications, consent management, lack fair incentives providers. With their transparency, immutability, non-repudiation, decentralization properties, blockchains could not be more apt answer enhance trust in a platform. However, are good at handling four Vs big...
An Intelligent IoT Environment (iIoTe) is comprised of heterogeneous devices that can collaboratively execute semi-autonomous applications, examples which include highly automated manufacturing cells or autonomously interacting harvesting machines. Energy efficiency key in such edge environments, since they are often based on an infrastructure consists wireless and battery-run devices, e.g., e-tractors, drones, Automated Guided Vehicle (AGV)s robots. The total energy consumption draws...
As Machine Learning (ML) models are becoming increasingly complex, one of the central challenges is their deployment at scale, such that companies and organizations can create value through Artificial Intelligence (AI). An emerging paradigm in ML a federated approach where learning model delivered to group heterogeneous agents partially, allowing train locally with own data. However, problem valuation models, as well questions incentives for collaborative training trading data/models, have...
Network virtualization is one of the most promising technologies for future networking and considered as a critical information technology resource that connects distributed, virtualized cloud computing services different components such storage, servers, application. allows multiple virtual networks to coexist on same shared physical infrastructure simultaneously. One crucial factors in network embedding which provisions method allocate substrate resources requests. In this article, we...
Distributed Ledger Technologies (DLTs) are playing a major role in building security and trust Internet of Things (IoT) systems. However, IoT deployments with large number devices, such as environment monitoring applications, generate send massive amounts data. This would vast transactions that must be processed within the distributed ledger. In this work, we first demonstrate Proof Work (PoW) blockchain fails to scale sizable connectivity infrastructure. To solve problem, present...
Across industries, there is an ever-increasing rate of data sharing for collaboration and innovation between organizations their customers, partners, suppliers, internal teams. However, many enterprises are restricted from freely due to regulatory restrictions across different regions, performance issues in moving large volume data, or requirements maintain autonomy. In such situations, the enterprise can benefit concept federated learning, which machine learning models constructed at...
This study considers for the first time role of rising import competition on employment in Vietnam. Using a differenced and instrumental variables approach, our shows that results contraction. Firms operating industries face greater have reduced employment. We also find strong evidence negative impact small very firms, as well period before Vietnam's World Trade Organization (WTO) accession. Our reveal previous studies at industry-level can provide biased estimates because not controlling...
