Social Foundations of Self IV: Self in Digital Communication

201
Since the early 2000s, computer-mediated communication (CMC) has grown rapidly, playing a crucial role in self-development. A key distinction between CMC and real-life interactions is the lack of a physically present partner. This absence makes non-verbal cues such as facial expressions, body language, and paralinguistic signals unavailable in CMC platforms like email, instant messaging, or social media. The lack of these cues can create ambiguity and complicate how feedback is interpreted.The...

Changes in the environment of the early Earth drove the evolution of organisms. As prokaryotic organisms in the oceans began to photosynthesize, they produced oxygen. Eventually, oxygen saturated the oceans and entered the air, resulting in an increase in atmospheric oxygen concentration, known as the oxygen revolution approximately 2.3 billion years ago. Therefore, organisms that could use oxygen for cellular respiration had an advantage. More than 1.5 years ago, eukaryotic cells and...

Uncertainty in Measurement: Reading Instruments

Counting is the type of measurement that is free from uncertainty, provided the number of objects being counted does not change during the process. Such measurements result in exact numbers. By counting the eggs in a carton, for instance, one can determine exactly how many eggs are there in the carton. Similarly, the numbers of defined quantities are also exact. For example, 1 foot is exactly 12 inches, 1 inch is exactly 2.54 centimeters, and 1 gram is exactly 0.001 kilograms. Quantities...

Uncertainty in Measurement: Significant Figures

All the digits in a measurement, including the uncertain last digit, are called significant figures or significant digits. Note that zero may be a measured value; for example, if a scale that shows weight to the nearest pound reads “140,” then the 1 (hundreds), 4 (tens), and 0 (ones) are all significant (measured) values.

Area of Science:

  • Gastroenterology and Hepatology
  • Minimally Invasive Endoscopic Procedures

Background:

  • The biliary ductal system requires direct visualization for accurate diagnosis and effective treatment.
  • Traditional methods for diagnosing biliary strictures and removing stones are often limited in scope and efficacy.

Purpose of the Study:

  • To review the technical evolution of cholangioscopy, particularly into the digital era.
  • To examine the clinical evidence supporting cholangioscopy in diagnosing and treating biliary tract diseases.

Main Methods:

  • Review of advancements in endoscopic and imaging technology for cholangioscopy.
  • Analysis of clinical studies and evidence for cholangioscopy applications.
  • Discussion of the expanded clinical uses of the latest generation cholangioscopes.

Main Results:

  • Cholangioscopy is crucial for diagnosing indeterminate biliary strictures.
  • It serves as an essential therapeutic tool for managing difficult biliary stones.
  • New cholangioscopes enable tumor ablation, gallbladder drainage, and foreign body removal.

Conclusions:

  • Digital cholangioscopy represents a significant advancement in visualizing and treating biliary diseases.
  • Its expanded applications demonstrate its value beyond traditional uses, improving patient care for complex biliary conditions.
