In this blog post, we’ll start by examining the characteristics of animals—such as sharks and crocodiles—that continuously regenerate their teeth, then explore the principles of tooth regeneration technology using stem cells and dental buds, along with its research achievements, limitations, and future potential.   Can We Regrow Teeth? Even the lion, the king of beasts, finds it difficult to...

In this blog post, we’ll take a natural and easy-to-understand look at the meaning and importance of dimensional tolerances—a key concept that enables the quality and mass production of mechanical products.   Why Are Dimensional Tolerances Important? President Jeong had a firm ambition to develop a new South Korean-made ballpoint pen to compete with high-tech Japanese products and pioneer...

In this blog post, we’ll explore how reinforcing bars and concrete complement each other’s weaknesses and have become core materials in modern construction structures.   Most of the buildings around us are made of steel structures and concrete structures. A steel structure refers to a structure that uses steel materials—such as structural steel, steel plates, and steel pipes—as its primary...

In this blog post, I will examine the core arguments of creationism and evolution, with a focus on “intelligent design,” and share my views on them.   At some point in their lives, everyone has asked themselves, “How did humans first come to be?” To answer this question, creationism and evolution have been in sharp conflict for over 200 years. Creationism is the view that the origins of...

In this blog post, we will examine whether evolutionary psychology can indeed be considered a science, based on various criteria from the philosophy of science.   Evolutionary psychology is a field of study that seeks to understand human psychology from an evolutionary perspective. It is primarily based on evolutionary biology and cognitive psychology, particularly computational theories of...

In this blog post, we will examine the various interpretations of evolutionary theory and their implications, focusing on the debate between gene selection theory and multilevel selection theory.   Evolutionary theory has long been one of the topics where science and religion have clashed most sharply. The biblical verse, “Let us make humankind in our image!” (Genesis 1:26), represents the...

In this blog post, using the movie ‘The Matrix’ as a starting point, we’ll explore whether the concepts of “real” and “fake” actually exist, and why that distinction might be illusory.   Imagine you’re an ordinary office worker when a stranger wearing black sunglasses approaches you. He hands you a red pill and a blue pill and says, “This world is ‘fake.’ Come with me to the...

In this blog post, based on my firsthand experience visiting Sonagi Village at the Hwang Sun-won Literary Village in Yangpyeong, I will examine the challenges facing regional literary museums in South Korea and, by comparing them with examples from abroad, reflect on the direction these museums should take in the future.   The Literary Space I Experienced at Hwang Sun-won Literary Village’s...

In this blog post, we’ll explore the characteristics of zirconia crowns used for dental implants and the principles behind enhancing their strength, while also examining how modern dental materials have evolved.   What Kind of Material Is Zirconia Used in Dental Implants? When you think of actor Lee Byung-hun, the first thing that comes to mind is his smile, which reveals his white, healthy...

In this blog post, we’ll examine the mechanisms behind global warming, its impact on the Earth’s environment, and the international community’s efforts to mitigate and respond to it.   Even people who aren’t interested in environmental issues have likely heard the term “global warming” at least once through newspapers or the media, and they probably have a vague understanding that it is a...
