Nuclear power plants are designed to keep the concentration of uranium tightly controlled to prevent a nuclear bomb-like explosion. In the Fukushima and Chernobyl accidents, where radioactive material leaked due to a damaged cooling system, safeguards have been strengthened in recent years. However, in addition to technical safety, transparent operations and the prevention of corruption are...

Sweaty clothes during intense exercise can lower your body temperature and reduce your performance. This increases the risk of hypothermia, especially in cold environments, which emphasizes the need for technical fabrics that wick moisture away quickly. For example, Coolmax fibers made from polyester wick sweat away from the skin through capillary action to keep you cool, and are also cold and...

Science has been trusted since the modern era as an indisputable truth, but in the mid-20th century, Thomas Kuhn shook this belief by arguing in The Structure of Scientific Revolutions that scientific progress is driven by cyclical revolutions. Kuhn explained that science chooses new paradigms based on irrational rather than rational factors, and this led to a shift away from blind faith in...

  The match between Lee Sedol 9 and AlphaGo demonstrated that AI can go beyond mere computation and challenge human intuition. AlphaGo was able to use deep learning and CNN to learn the patterns of the game of Go and make intuitive judgments like a human, suggesting the potential for AI to be applied in a wider range of fields. As deep learning technology becomes more advanced, AI will play...

Most people have fantasized about time travel and the future at some point in their childhood. The deterministic worldview, in which the future can be predicted according to scientific laws, was once a strong belief, but it was shaken by the discovery of Heisenberg’s uncertainty principle. The future is not set in stone and can change depending on our choices and actions. Instead of trying...

  This article discusses whether technologies such as smartphones, the wheel, and computers are at the center of social change, or whether social needs drive technology. It explains the evolution of each technology and its impact on society from the perspectives of technological determinism and social constructionism, emphasizing the technological determinist position that technology has...

Smartphones, which most people hold in their hands on the way to work, are more than just a phone, they play an essential role in many aspects of our daily lives. From the first generation, which combined the functions of a phone and PDA, to the second generation, which allowed users to manage real-time information and personal information without a PC, to the third generation, which expanded...

To achieve equality of educational opportunity, she argues that volunteerism and changes in the public education system are needed together, and that these...

Plastic surgery is not only aesthetic, but also reconstructive surgery, which plays an important role in restoring bodily functions and improving quality of life, and it continues to evolve in combination with various advanced technologies. Initially aimed at restoring the body after burns or accidents, it has now reached the level of mimicking the body’s original functions, such as...

The death penalty is inhumane, has the potential to victimize innocent people, and can be used as a political tool in autocratic regimes. It is also not proven to deter crime, and countries that have abolished the death penalty have lower crime rates. For the sake of respect for life and social safety, the death penalty should be abolished, and alternatives include strengthening social safety...
