- 医療診断
- ヘルスケアにおける人工知能
- 結核研究
背景:
- 中央TB部門は、ラインプローブアッセイ(LPA)ストリップを解釈するための人工知能(AI)ツールを開発しました。
- 18,000以上のLPAストリップが、培養および薬剤感受性試験研究所全体でトレーニングと検証に使用されました。
- AIツールのパフォーマンスを検証するために、ICMR-NIRTによる独立した評価が実施されました。
主な方法:
- AIシステムは、ストリップ検出にFaster R-CNN、バンド局在化にDETR、分類に階層型ニューラルネットワーク(HNN)を利用しています。
- 独立した検証には、10の中間参照研究所全体で2810の第一選択(FL-LPA)および241の反射第二選択(SL-LPA)テストが含まれました。
- パフォーマンスは、主要な遺伝子の精度、感度、特異性、およびF1スコアを含む指標を使用して評価されました。
結論:
- AIシステムは、LPA解釈のための新規でモジュール化されたスケーラブルなソリューションを提供し、専門の読者と同等のパフォーマンスを発揮します。
- このAIツールの採用は、解釈時間を大幅に短縮し、結果の均一性を向上させることができます。
- AIツールは、インド全土の治療提供を改善することにより、TB根絶の国家目標をサポートします。

Intelligence

The term "intelligence" is complex because it refers to both behavior and individuals, and its interpretation varies across cultures. European Americans tend to link intelligence with reasoning and cognitive skills, while in Kenya, it is tied to responsible participation in family and social life. In Uganda, intelligence is seen as the ability to know the right actions and carry them out effectively, while the Iatmul people of Papua New Guinea associate it with the capacity to remember...

Measures of Intelligence

Psychologists measure intelligence by using standardized tests that produce a score known as the intelligence quotient or IQ. To understand IQ tests, it's important to recognize the key principles behind their construction: validity, reliability, and standardization.
Validity refers to how well a test measures what it claims to measure. An intelligence test should accurately assess intelligence rather than another characteristic, like anxiety. Criterion validity is one way to evaluate this;...

Pulmonary Tuberculosis I

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Pulmonary Tuberculosis II

Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

Pulmonary Tuberculosis V

Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the...

Multiple Intelligences Theory

Howard Gardner's theory of Multiple Intelligence proposes that there are nine distinct types of intelligence, each reflecting different ways of interacting with the world. Introduced in 1983 and expanded in subsequent years, Gardner's framework challenges the traditional notion of a single, generalized intelligence.
