Issues And Trends In Healthcare Delivery System

5.6K
The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.
Cost Containment
Payment for healthcare services has historically promoted adoption of costly and often unnecessary or inefficient...

Maximum Size of Aggregate01:12

Maximum Size of Aggregate

94
The maximum size of aggregate is defined as the aperture of the sieve retaining 15 percent or more of the particles present in the aggregate sample. The aggregate's maximum size impacts the concrete's water requirement, workability, and strength. Larger aggregates reduce the surface area needing cement paste coverage, which can lower water needs, thereby allowing a decrease in the water-to-cement ratio when the desired workability and richness of the mix are to be maintained, which can...

Distribution Reliability and Automation

107
Distribution reliability in electrical power systems is critical for ensuring an uninterrupted power supply to consumers at minimal cost. According to IEEE Standard Terms, reliability is the probability that a device will function without failure over a specified time period or amount of usage. For electric power distribution, this translates to maintaining continuous power supply and addressing customer concerns over power outages. Several indices, as defined by IEEE Standard 1366-2012, are...

Integrated Healthcare System01:20

Integrated Healthcare System

1.5K
An integrated healthcare system (IHS) is a set of organizations that provides for or arranges to provide coordinated and continuous service to a defined population. The IHS takes responsibility for that particular population's health status and outcome, both clinically and fiscally. An integrated healthcare system is a well-organized, well-coordinated, and collaborative network. The integrated delivery system is a network that connects different healthcare providers to deliver organized,...

Unsoundness of Aggregate due to Volume Change01:26

Unsoundness of Aggregate due to Volume Change

98
Unsoundness in aggregates due to volume changes is primarily caused by the physical alterations aggregates undergo, such as freezing and thawing, thermal changes, and wetting and drying. Unsound aggregates, when subjected to these changes, result in volume change upon disintegration. This, in turn, contributes to the deterioration of concrete, including scaling, pop-outs, and cracking. Particular types of aggregates, such as porous flints, cherts, and those containing clay minerals, are...

Area of Science:

  • Blockchain Technology
  • Internet of Things (IoT)
  • Cryptography

Background:

  • Oracles are crucial for bridging real-world data with blockchain systems, essential for IoT applications.
  • Securing data privacy in distributed Oracle machines is a significant challenge for protecting blockchain data value.
  • Existing Oracle systems face issues with data sharing, device management, and potential fraud from dishonest nodes.

Purpose of the Study:

  • To propose an improved scheme for distributed Oracle data aggregation.
  • To achieve end-to-end data privacy protection from IoT devices to blockchain users.
  • To address the financial risks associated with dishonest distributed Oracle machines.

Main Methods:

  • Implementation of an improved distributed Oracle data aggregation scheme using the Paillier encryption algorithm.
  • Development of the Paillier-based InChain Aggregation (PICA) algorithm to mitigate risks of dishonest Oracles.
  • Integration of random numbers and traffic coverage methods to enhance security and obscure request paths.

Main Results:

  • The proposed scheme provides end-to-end data privacy protection for IoT data on the blockchain.
  • The PICA algorithm effectively addresses the issue of dishonest Oracle machines running out of funds.
  • Simulations in IoT scenarios with 10,000 nodes show a data acquisition delay of approximately 2s per false request, with a 20s overall response time.

Conclusions:

  • The developed scheme successfully enhances data privacy in distributed Oracle systems.
  • The PICA algorithm offers a robust solution against fraudulent activities in Oracle networks.
  • The findings are particularly relevant for small to medium-sized IoT applications requiring secure data handling.
