Traditional Chinese medicine with its effectiveness should also have stemmed out from such logic system. This article aims to rearticulate the underlying lucid multi-dimensional logic system, which faded in obscurity only because of time-out loss of the mid-right concept. Retracing this past tacit but important concept could uncover a multi-dimensional system over a point relating to all matters while capturing the central core of the matter. The seemingly unmanageable multidimensional logic was strengthened by verification processes which affirmed its further extensions, and made up the language of the people, the concepts of yin-yang(阴阳), and the development of extensions of Ba Gua(八卦) derivatives, which furthered the interpretation of the space-time properties and Chinese medicine.展开更多

文摘The ancient tacit knowledge behind the logic system permeated the culture and promoted numerous impactful inventions throughout the history. Traditional Chinese medicine with its effectiveness should also have stemmed out from such logic system. This article aims to rearticulate the underlying lucid multi-dimensional logic system, which faded in obscurity only because of time-out loss of the mid-right concept. Retracing this past tacit but important concept could uncover a multi-dimensional system over a point relating to all matters while capturing the central core of the matter. The seemingly unmanageable multidimensional logic was strengthened by verification processes which affirmed its further extensions, and made up the language of the people, the concepts of yin-yang(阴阳), and the development of extensions of Ba Gua(八卦) derivatives, which furthered the interpretation of the space-time properties and Chinese medicine.
文摘The purpose of this study was to describe and analyze how and why contradictions recurrently arise regarding how incoming emergency calls at dispatch centers should be assessed,sorted,and handled.The study is based on data from documents,study visits,and interviews with representatives from dispatch operators in a Swedish context.The results identify competing alarm and healthcare logics that are incompatible,which leads to contradictions between the national and regional approaches and,consequently,makes collaboration more difficult and affects the precision of emergency call assessment.The study also shows that the assessments of emergency calls are governed more by which logic is applied than by the assessor's formal competence.The study highlights the importance of feedback and subsequent analysis from the health service to the initial call assessment stage,which can improve the alarm logic's weaknesses with over-triage,without extending the response time.We also focused on the mechanisms required to develop and maintain a long-term sustainable alarm function.
文摘Historical thinking refers to a cognitive activity or process that integrates general thinking with specific thinking activities unique to the history discipline.Historical thinking skills,therefore,represent the ability to solve problems demonstrated within the context of historical thinking activities.Cultivating high school students’historical thinking skills requires teachers to familiarize themselves with the fundamental characteristics of students’historical thinking,guide them in deeply understanding the basic concepts and principles of historical thinking,refine their cognitive structures,innovate teaching,learning,and evaluation methods,and stimulate intrinsic motivation for learning.This is not only a vital field of theoretical research in high school history education but also a key aspect of the reform and development of history teaching in secondary schools.

文摘Artificial intelligence(AI)is rapidly transforming healthcare and medical education.Strong statistical thinking skills are vital for evaluating and applying AI tools.However,traditional medical statistics education has not adapted to this demand.This paper first analyzes the connotation and importance of statistical thinking,points out the significant challenges currently faced by medical statistics education,and then proposes strategies such as innovative teaching methods combined with evidence-based medicine,utilizing AI platforms for supplemental teaching,multidisciplinary integration,and strengthening the understanding of the statistical foundations of AI to enhance the statistical thinking abilities of medical professionals.This study emphasizes the importance of cultivating medical statistical thinking in the era of AI to improve the quality of medical education and ensure the safety and effectiveness of future medical services.
