Frames01:30

Frames

Frames are essential components of various mechanical and structural systems used daily. These structures are known for their stability and ability to bear heavy loads. A frame is constructed using two-force and multi-force members, interconnected using pin joints. In contrast, trusses are made entirely of two-force members.
Frames are versatile and widely used in various applications such as structural supports for beams and columns, automobile chassis construction, and in the construction...

Framing Effects

Information is everywhere and its presentation—such as how and when items are presented—can impact our perceptions and decisions surrounding the info. This broad concept umbrellas framing effects—influences that occur due to the way information is framed in its appearance, whether it’s purely the order or the specific wording of a message. Let’s take a look at numerous ways in which two versions of something can objectively say the same thing, yet we respond in different ways based on the...

Methods of Documentation I: Source-Oriented Records

Source-oriented records, or SOR, are medical record-keeping organized by the data source. The SOR system was first developed in the mid-1900s to organize the growing patient data in hospitals and other healthcare facilities.
In an SOR, each discipline involved in patient care maintains a separate medical record section. This record-keeping method enables easy tracking of patient progress and ensures healthcare staff have access to up-to-date information.
Key Attributes include the following:
Frames: Problem Solving II01:26

Frames: Problem Solving II

Consider a hydraulic hoist supporting a load of 1 kN. Assuming a simplified schematic representation of this frame structure, the force acting on BD and BF members can be determined.
Methods of Documentation III: PIE01:21

Methods of Documentation III: PIE

Problem-intervention-evaluation (PIE) is a systematic approach to documentation used in healthcare settings for clinical decision-making and patient care planning. It is a structured approach to organizing patient data based on problems, interventions, and evaluations. Here's a breakdown of its key features and considerations:
Frames: Problem Solving I01:24

Frames: Problem Solving I

Consider a jib crane with an external load suspended from the pulley. The dimensions of the crane members are shown in the figure. A systematic analysis of the frame structure is required to determine the reaction forces at the pin joints, assuming that the pulleys are frictionless.

Area of Science:

  • Natural Language Processing
  • Clinical Informatics
  • Computational Linguistics

Background:

  • Operative notes contain rich clinical data valuable for evidence-based medicine and research.
  • Automated extraction of surgical details from these notes is crucial for clinical research.
  • Existing methods may not fully capture the nuances of surgical procedures described in text.

Purpose of the Study:

  • To develop Predicate Argument Structure (PAS) frames for surgical action verbs.
  • To facilitate the creation of an information extraction (IE) system for operative notes.
  • To automatically extract surgical techniques, equipment, and steps.

Main Methods:

  • Created PropBank-style PAS frames for 30 top surgical action verbs.
  • Analyzed sample sentences from 3,000 Laparoscopic Cholecystectomy notes.
  • Evaluated frame completeness on 6 other gastrointestinal surgical procedures.

Main Results:

  • The developed PAS frames effectively represent surgical action verbs.
  • Frames created for one surgery type generalized to other gastrointestinal procedures.
  • Demonstrated the utility of PAS frames for information extraction in surgery.

Conclusions:

  • Predicate Argument Structure frames are a viable approach for surgical information extraction.
  • PAS frames enhance the ability to analyze operative notes for clinical research.
  • This method supports the development of robust IE systems for surgical text.
