Short-distance Transport of Resources02:12

Short-distance Transport of Resources

17.7K
Short-distance transport refers to transport that occurs over a distance of just 2-3 cells, crossing the plasma membrane in the process. Small uncharged molecules, such as oxygen, carbon dioxide, and water, can diffuse across the plasma membrane on their own. In contrast, ions and larger molecules require the assistance of transport proteins due to their charge or size. Transport across membranes also occurs within individual cells, playing a variety of essential roles for the plant as a whole.

Healthcare Agencies II

1.1K
There are various healthcare agencies in the United States—some of which are managed by religious institutions and others by different government branches.
Parish nursing is a growing specialty nursing profession that focuses on holistic healthcare, health promotion, and illness prevention. It blends professional nursing practice with a health ministry, focusing on health and healing within the context of a Christian community. Parish nurses serve as health educators, referral sources,...

Secondary Healthcare System01:11

Secondary Healthcare System

2.1K
Secondary healthcare is offered by a specialist, generally in hospitals or clinics for patients referred by primary healthcare providers. It occurs when a person has an illness or injury that requires specific medical care. Secondary care is often referred to as acute care. Secondary care can range from uncomplicated care to repair a minor laceration or treat a strep throat infection to more complicated emergent care, such as treating a head injury sustained in an automobile accident. Whatever...

Tertiary Healthcare System01:21

Tertiary Healthcare System

2.2K
Specialized care provided over an extended period is called tertiary care. Usually, a primary or secondary care physician will refer a patient to tertiary care. A patient's maximum physical and mental function is restored in tertiary care, which is caused due to the impact of a chronic illness or condition. Tertiary care aims to achieve the highest level of functioning possible while managing chronic illness. For example, a patient who falls and fractures their hip will need secondary care...

Healthcare Agencies I

1.2K
Healthcare agencies provide healthcare services to people. In the United States, voluntary agencies are often non-profit centers sponsored by donations, grants, or fundraisers. One such organization is Meals on Wheels, which provides meals to the elderly and homebound. The American Heart Association and the American Lung Association are other non-profit community organizations. Doctors and nurses are frequently active members of these organizations, which offer health checks and educational...

Integrated Healthcare System01:20

Integrated Healthcare System

2.4K
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,...

Area of Science:

  • Data Science
  • Health Informatics
  • Knowledge Management

Background:

  • Effective data science relies on understanding available datasets, their content, and structure.
  • A gap exists in user-specific information resources for navigating complex datasets.
  • The Dataset Information Resource (DIR) was developed to address this need.

Purpose of the Study:

  • To create a user-oriented Dataset Information Resource (DIR) tailored for specific user needs.
  • To assist entry-level data scientists in identifying, understanding, and analyzing healthcare datasets.
  • To provide comprehensive knowledge about datasets, not the data itself.

Main Methods:

  • Leveraged Semantic Web technologies and the W3C Dataset Description Profile for knowledge representation.
  • Employed manual and semi-automatic extraction methods (NLP-based) from documentation and publications.
  • Integrated a semantic query component and parameterized question-answering for efficient knowledge retrieval.

Main Results:

  • Developed a DIR prototype with four components: metadata/knowledge, search, Q&A, and blogs.
  • Currently includes information on 12 complex healthcare datasets.
  • Initial evaluations show the DIR is helpful and beginner-friendly for health informatics novices.

Conclusions:

  • A novel, user-oriented DIR effectively represents dataset knowledge using Semantic Web technologies.
  • The DIR provides specialized knowledge to aid entry-level health informaticians in healthcare data analysis.
  • Ongoing development aims to enhance both content and functionality of the DIR.
