Centroid of a Body: Problem Solving01:03

Centroid of a Body: Problem Solving

The centroid of a body is a crucial concept in engineering and physics. Finding the centroid of a body can help determine its stability, its balance point, and even its design. In this context, consider a thin wire bent in the form of a quarter circular arc. Polar coordinates are used to calculate the centroid. The wire is first divided into small differential elements of a length equal to the radius multiplied by the differential angle.
The x-coordinates and y-coordinates of each element's...

Higher Mental Functions of the Brain: Language

Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

Clearance Models: Physiological Models

Drug clearance is a critical pharmacokinetic process involving the irreversible removal of drugs from the body through various organs over a specified time period. Physiological models are indispensable in determining organ-specific clearance, defined by the proportion of the drug eliminated per unit of time from the organ's blood volume.
The organ's clearance rate depends on the blood flow to the organ and the extraction ratio (E). The extraction ratio describes the organ's proficiency in drug...
Language and Cognition01:27

Language and Cognition

Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

科学领域:

  • 数字健康数字健康
  • 医疗保健中的人工智能
  • 人与计算机的交互

背景情况:

  • 基于大型语言模型 (LLM) 的对话代理越来越多地用于数字健康.
  • 它们在身体活动 (PA) 和认知训练 (关键的福祉领域) 中的应用需要系统地绘制.
  • 这些领域需要个性化,适应性支持和对话参与,使它们适合LLM代理部署.

研究的目的:

  • 系统地绘制基于LLM的对话代理的范围,特征和设计实践,用于PA和认知训练.
  • 分析这些代理的应用环境,社会角色和技术特征.
  • 了解目前在这些福利领域的LLM应用的现状.

主要方法:

  • 根据PRISMA-ScR指南进行范围审查.
  • 从2018年1月到2024年12月,搜索了主要的学术数据库 (科学网络,Scopus,PubMed,ACM,IEEE Xplore).
  • 包括描述PA或认知训练的LLM代理人的研究,使用描述性合成和框架分析.

主要成果:

  • 10项研究符合资格标准 (7项PA,3项认知培训).
  • 代理人主要担任PA的教练角色和认知训练的伴侣/脚手架角色.
  • 专有LLM (GPT-3.5,GPT-4,Bard) 占主导地位;即时工程是关键,但报告不一致;结果侧重于感知到的有用性和参与度,而不是行为变化.

结论:

  • LLM代理商对PA和认知培训支持有着早期的承诺,但证据是探索性的和有限的.
  • 挑战包括不一致的快速报告,依赖专有模型和缺乏标准化的结果措施.
  • 需要更严格,更透明的评估来加强证据,并指导未来基于LLM的数字健康发展.
