Issues And Trends In Healthcare Delivery System

5.8K
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...

Buffer Effectiveness02:19

Buffer Effectiveness

49.9K
Buffer solutions do not have an unlimited capacity to keep the pH relatively constant . Instead, the ability of a buffer solution to resist changes in pH relies on the presence of appreciable amounts of its conjugate weak acid-base pair. When enough strong acid or base is added to substantially lower the concentration of either member of the buffer pair, the buffering action within the solution is compromised.
The buffer capacity is the amount of acid or base that can be added to a given volume...

Production Efficiency

Net production efficiency (NPE) is the efficiency at which organisms assimilate energy into biomass for the next trophic level. Due to low metabolic rates and less energy spent on thermoregulatory processes, the NPE of ectotherms (cold-blooded animals) is 10 times higher than endotherms (warm-blooded animals).

Social Exchange Theory

We have discussed why we form relationships, what attracts us to others, and different types of love. But what determines whether we are satisfied with and stay in a relationship? One theory that provides an explanation is social exchange theory. According to social exchange theory, we act as naïve economists in keeping a tally of the ratio of costs and benefits of forming and maintaining a relationship with others (Rusbult & Van Lange, 2003).

Stream Function01:20

Stream Function

In two-dimensional incompressible fluid flow, the continuity equation is essential for ensuring mass conservation, meaning that any change in fluid entering or exiting a region is balanced by a corresponding change elsewhere. For incompressible flow, where density remains constant, this requirement simplifies to the condition that the divergence of the velocity field must be zero. Mathematically, this is expressed as,

Area of Science:

  • Computer Science
  • Digital Forensics
  • Intellectual Property Law

Background:

  • Digital content, particularly multimedia, faces significant copyright infringement issues online.
  • Unauthorized modifications to digital resources infringe on intellectual property rights.
  • Existing systems struggle to provide secure and transparent management of digital assets.

Purpose of the Study:

  • To propose a novel decentralized framework for video copyright protection.
  • To address insecurity and openness issues related to digital multimedia assets.
  • To facilitate secure, transparent, and immutable transactions for creative work ownership.

Main Methods:

  • Development of a decentralized framework utilizing Inter Planetary File System (IPFS) and blockchain technology.
  • Implementation of a Solidity-based smart contract on the Ethereum network for video registration and copyright checks.
  • Utilizing perceptual hashing (Phash) to compare original and modified video content for dispute resolution.
  • Generation of IPFS hash values to signify video content ownership.

Main Results:

  • The framework successfully registers videos and performs copyright checks using smart contracts.
  • Perceptual hashing (Phash) and IPFS hash values are compared on the Ethereum blockchain.
  • Performance evaluation in Hyperledger Caliper showed video registration latency of 5.02s and throughput of 409.87/s.
  • Video verification demonstrated a latency of 4.57s and throughput of 484.23/s.

Conclusions:

  • The proposed decentralized framework effectively enhances video copyright protection.
  • Blockchain and IPFS integration provides a secure, transparent, and immutable system for digital asset management.
  • The framework offers a viable solution for verifying video integrity and ownership in the digital space.
