Computed Tomography01:10

Computed Tomography

8.3K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Nursing Process for Patient and Caregiver Teaching II: Planning and Implementation

2.1K
Planning for learning involves the development of a teaching plan. Teaching plans are similar to nursing care plans—both follow the steps of the nursing process. Planning in the teaching process involves setting goals and outcomes. Here, goals identify what a patient needs to achieve to understand a healthcare topic better, whereas the outcomes are the action to be performed by the patient to achieve the goal within a timeframe. For example, if the goal is to educate the patient about...

Persuasion Strategies01:52

Persuasion Strategies

43.5K
Researchers have tested many persuasion strategies, including the foot-in-the door and the door-in-the-face techniques, in a variety of contexts. Ultimately, the principles are effective in selling products and changing people’s attitude, ideas, and behaviors (Cialdini & Goldstein, 2004).

Design Example: Traverse Angle Computations

341
Traverse angle computations are a critical component of surveying, used to compute the internal angles within a closed traverse. A traverse consists of a series of connected lines forming a closed loop, often used for land boundary delineation or mapping. Calculating the internal angles ensures accuracy in the traverse geometry and is essential for checking survey data integrity.The process begins with known azimuths and bearings of the traverse sides. Internal angles at each vertex are...

Coping Strategies: Problem Focused01:27

Coping Strategies: Problem Focused

506
Coping strategies are methods people use to manage, tolerate, or reduce the effects of stressors. These strategies involve both behavioral and psychological actions to handle stressful situations. One common approach is problem-focused coping, which aims to change or eliminate the source of stress rather than merely addressing its consequences. This method involves taking direct action to resolve the issue causing stress.
For example, consider a student who struggles to understand their...

Nursing Process for Patient and Caregiver Teaching I: Assessment and Diagnosis

2.4K
The nursing process provides a clinical decision-making framework for patients and families to establish and implement a personalized care plan. Since part of the nurse's duties is to teach patients, the steps of the nursing process are the most effective way to approach instruction. The nursing process and the teaching-learning process are inextricably linked.
It is critical to determine the patient's learning needs during the assessment. Determination of learning needs compounds data...

Area of Science:

  • Biochemistry Education
  • Computational Biology
  • Structural Biology

Background:

  • Traditional biochemistry teaching often struggles with visualizing complex molecular structures.
  • Understanding protein and DNA structures is fundamental for biology and pharmacy students.

Purpose of the Study:

  • To evaluate a computational strategy for visualizing three-dimensional (3D) protein and DNA structures.
  • To assess the impact of this strategy on student comprehension of key biochemistry concepts.
  • To gauge student perceptions of the visualization tool's effectiveness.

Main Methods:

  • Utilized computational techniques and 3D structure visualization software (Swiss PDB Viewer) with data from the Protein Data Bank.
  • Conducted practical classes with 76 undergraduate biology and pharmacy students.
  • Administered pre- and post-activity questionnaires to assess knowledge and gather opinions.

Main Results:

  • A significant increase in correct answers was observed, rising from 35.53% pre-activity to 75.91% post-activity.
  • 100% of students agreed the activity contributed to learning DNA and protein structures.
  • Approximately 90% of students found the visualization aided learning and understanding.

Conclusions:

  • The computational visualization strategy is effective in contextualizing biochemistry themes.
  • This approach can serve as a valuable complement to traditional theoretical classes.
  • Interactive 3D molecular visualization enhances student engagement and learning in biochemistry.
