Issues And Trends In Healthcare Delivery System

Issues And Trends In Healthcare Delivery System

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...

Ion-Exchange Chromatography

Ion-Exchange Chromatography

Ion-exchange chromatography, or IEC, is a technique for separating ions based on their affinity for the stationary phase. The stationary phase is a cross-linked polymer resin with covalently attached ionic functional groups. The functional groups can be either positively charged (cation exchangers) or negatively charged (anion exchangers). A cation exchanger consists of a polymeric anion and active cations, while an anion exchanger is a polymeric cation with active anions. The choice of...

IP3/DAG Signaling Pathway

IP3/DAG Signaling Pathway

Membrane lipids such as phosphatidylinositol (PI) are precursors for several membrane-bound and soluble second messengers. Specific kinases phosphorylate PI and produce phosphorylated inositol phospholipids. One such inositol phospholipids are the phosphatidylinositol-4,5 bisphosphate [PI(4,5)P2], present in the inner half of the lipid bilayer. Upon ligand binding, GPCR stimulates Gq proteins to turn on phospholipase Cꞵ. Activated phospholipase Cꞵ cleaves PI(4,5)P2 and...

Background:

Blockchain offers decentralized, transparent, and tamper-proof traceability but faces challenges with data explosion and IoT device data reliability.
Integrating diverse enterprise data storage structures increases costs for data sharing in traditional systems.

Purpose of the Study:

To develop a trustworthy product traceability system using Hyperledger Fabric and EPCIS.
To address challenges of data explosion, device authentication, and data sharing in blockchain-based systems.

Main Methods:

Implemented an on-chain and off-chain collaborative data management mechanism.
Developed a blockchain-based scheme for authenticating and authorizing Internet of Things (IoT) devices.
Ensured compliance with Electronic Product Code Information Service (EPCIS) and Core Business Vocabulary (CBV) standards, including an EPCIS location discovery service.

Main Results:

The system provides reliable product information traceability, data tamper-proofing, and data confidentiality.
Successfully authenticated and authorized IoT devices for data collection, ensuring data source reliability.
Demonstrated improved interactivity through the EPCIS location discovery service.

Conclusions:

The proposed system effectively enhances product traceability and data integrity.
The on-chain/off-chain approach mitigates data explosion issues.
The solution offers a reliable and secure framework for blockchain-based product traceability.
