Myopia Epidemic

Myopia is the most common ocular disorder worldwide, it is the leading cause of visual impairment in children, and its incidence is increasing rapidly.1,2 In 2010, an estimated 1.9 billion people (27% of the world’s population) were myopic, and 70 million of them (2.8%) had high myopia. These numbers are projected to rise to 52% and 10%, respectively, by 2050 (Figure).1

Myopia is a major public health concern in many East Asian countries, where the condition affects 80% to 90% of high school graduates. Of these individuals, 10% to 20% have sight-threatening pathologic myopia.2,3

Vision impairment related to myopia has a significant economic impact and a significant effect on quality of life regarding patients’ physical, emotional, and social functioning.4 Smith et al estimated the loss in world productivity caused by uncorrected myopic refractive error in 2004 to be 268.8 billion international dollars and the cost of addressing this problem to be US$28 billion.5

Carbon Capture & Storage

-
  Carbon Capture & Storage Carbon capture and storage (CCS) is the process of capturing and storing carbon dioxide (CO 2 ) before it is released into the atmosphere. The technology can capture  up to 90%  of CO 2  released by burning fossil fuels in electricity generation and industrial processes such as cement production. CO 2  can be captured using different methods. The main ones are: post-combustion, pre-combustion and oxyfuel. Post-combustion technology removes CO 2  from the flue gases that result from burning fossil fuels. Pre-combustion methods – carried out before burning the fossil fuel – involve  converting the fuel into a mixture of hydrogen and CO 2 .  Oxyfuel technology  produces CO 2  and steam by burning fossil fuels with almost pure oxygen. Post-combustion and oxyfuel equipment can be fitted to new plants or retrofitted – in other words, added to existing power stations that were originally built without it. Pre-combustion methods require large modifications to e

Competition for talent

  Competition for talent As demand grows for new and emergent  skills , including UX design, cybersecurity, and data science, workers around the world — and labor markets — are struggling to keep up.  According to a recent  survey  conducted by the World Economic Forum, nearly eight in 10 global CEOs say they’re concerned about the availability of people with the right skills. So far, organizations have responded by engaging in a war for talent — that is, buying or stealing it, rather than growing it from within. As they compete to fill roles, many have been willing to spend billions on recruiting (or poaching), while reluctant to invest in training their existing workers or unskilled ones, perhaps out of fear their competitors will hire those newly attractive employees away.  Demand for skills as people retire early and pay levels depressed.

  AI Mentors - personal life, business life, coach The term AI mentor is a concept that brings together AI and machine learning to help humans in different aspects of life or mentoring them to get better.  AI mentors will be responsible for: Determining what you need to learn Optimizing learning by helping you identify and fill knowledge gaps Delivering personalized education Ai will improve trial and error learning by imparting knowledge through a machine rather than being scolded by a strict teacher will improve a students' learning. Intelligent tutoring is currently being used to teach Air Force technicians how to diagnose different electrical system problems in an aircraft perfectly. Ai-driven programs can give teachers helpful feedback which is the key to improving learning techniques and enhancing your teaching skills.   From chatbots to warbots, there is nothing that AI hasn't touched, it is everywhere and bound to make revolutionary changes in every aspect of our lives,
