Dosage Regimens: Designs and Approaches

325
Designing a dosage regimen, which refers to the manner of drug administration, is a complex process involving the selection of drug dose, route, and frequency. This process is underpinned by pharmacokinetic parameters derived from tests and population averages. These parameters are then tailored to patient-specific variables such as diagnosis, demographics, and allergy status. Once therapy commences, therapeutic response monitoring is critical and achieved through clinical and physical...

Numerical Calculations

1.2K
In engineering applications, the representation of the numerical value is critical. Presenting or reporting the answer is one of the essential parts of engineering practices. Numerical calculations are performed using handheld calculators or computers since numerically accurate answers are always preferred.
The solution to a problem is obtained using different methods. While manually solving algebraic symbols is one of the most common methods, the graphical method is often preferred. Computers...

Group Design

10.7K
The most basic experimental design involves two groups: the experimental group and the control group. The two groups are designed to be the same except for one difference— experimental manipulation. The experimental group gets the experimental manipulation—that is, the treatment or variable being tested—and the control group does not. Since experimental manipulation is the only difference between the experimental and control groups, we can be sure that any differences between...

Pilot and Numeric Relaying

492
Pilot relaying is a type of differential protection used in power systems. It compares electrical quantities at the terminals of equipment via a communication channel instead of direct relay interconnection. This method is essential for transmission lines where the terminals are far apart, typically up to 80 km for lines with 69 to 115 kV ratings. Four types of communication channels are used for pilot relaying:

How Data are Classified: Numerical Data

38.1K
Data that are countable or measurable in specific units are called numerical or quantitative data. Quantitative data are always numbers. Quantitative data are the result of counting or measuring the attributes of a population. Amount of money, pulse rate, weight, number of people living in a town, and number of students who opt for statistics are examples of quantitative data.
Quantitative data may be either discrete or continuous. All quantitative data that take on only specific numerical...

Factorial Design02:01

Factorial Design

14.0K
Factorial Analysis is an experimental design that applies Analysis of Variance (ANOVA) statistical procedures to examine a change in a dependent variable due to more than one independent variable, also known as factors. Changes in worker productivity can be reasoned, for example, to be influenced by salary and other conditions, such as skill level. One way to test this hypothesis is by categorizing salary into three levels (low, moderate, and high) and skills sets into two levels (entry level...

Area of Science:

  • Orthopedic Surgery
  • Biomechanical Engineering
  • Medical Device Design

Background:

  • Anatomically compliant osteosynthesis plates offer clinical advantages in fracture repair.
  • Traditional methods like cadaveric studies have limitations in sample size and objectivity for plate design.

Purpose of the Study:

  • To introduce a systematic numeric approach for anatomic osteosynthesis plate design.
  • To present a software tool utilizing a large 3D bone model database for assessing plate fit.

Main Methods:

  • Application of a SOMA software tool to evaluate the plate-to-bone distance of distal medial tibia plates.
  • Analysis of plate fit on 444 Caucasian and 310 Asian 3D bone models.

Main Results:

  • Significant differences in anatomical compliance were found between plate generations and manufacturers.
  • SOMA-designed plates demonstrated statistically superior anatomical compliance across all tested groups and ethnicities (P<0.001).

Conclusions:

  • A database-driven computational approach, exemplified by SOMA, is effective for developing advanced osteosynthesis plates.
  • This methodology leads to plates with enhanced anatomical compliance, potentially improving clinical outcomes in trauma surgery.
