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.

Minerals

Minerals are essential nutrients that the human body needs in small amounts to work properly. They play a vital role in many bodily functions, such as building strong bones and transmitting nerve impulses. Some minerals are needed for hormone production or to maintain a normal heartbeat. Major minerals include calcium, phosphorus, potassium, sulfur, sodium, chlorine, and magnesium, while trace minerals include iron, manganese, copper, iodine, zinc, cobalt, fluoride, and selenium.

Area of Science:

  • Geosciences
  • Computer Science
  • Information Systems

Background:

  • Mineral resource development faces challenges in traceability due to information asymmetry and data falsification.
  • Complex value chains hinder effective verification and data integrity.
  • Current traceability systems lack robustness against data manipulation.

Purpose of the Study:

  • To propose a comprehensive blockchain-enabled traceability evaluation framework for mineral resource development.
  • To enhance data integrity and accountability throughout the mineral lifecycle.
  • To provide a systematic methodology for assessing traceability performance.

Main Methods:

  • Development of a four-layer blockchain architecture (data acquisition, storage, analysis, application).
  • Construction of a hierarchical indicator system (breadth, depth, precision, timeliness, credibility).
  • Application of Analytic Hierarchy Process (AHP) and fuzzy comprehensive evaluation for assessment.

Main Results:

  • Empirical validation demonstrated the framework's applicability with a score of 81.2 (Good grade).
  • Blockchain systems achieved 96.8% data accuracy, compared to 82.4% for traditional methods.
  • Trace-back efficiency improved from 127.3 minutes to 4.7 minutes, with blockchain contributing 47.3% to this improvement.

Conclusions:

  • The proposed blockchain framework effectively addresses mineral traceability challenges.
  • Blockchain technology significantly enhances data accuracy, efficiency, and accountability in mineral supply chains.
  • The study provides a foundation for transparent and accountable mineral resource governance.
