In this blog post, we’ll explain the principles, examples, and real-world applications of Dijkstra’s algorithm in an easy-to-understand way.   Introduction Think back to the fairy tale “Hansel and Gretel.” When their stepmother abandoned the children in the forest, their first attempt—dropping pebbles to mark their path—failed, and their second attempt—leaving breadcrumbs—didn’t end in...

In this blog post, I’ll explain in simple terms the scope of resource processing engineering and why waste and carbon dioxide reduction technologies are so important.   The Department of Energy and Resource Engineering: Expectations vs. Reality When people hear the term “Department of Energy and Resource Engineering,” many immediately think of “renewable energy.” Many freshmen, myself...

In this blog post, we’ll examine the safety of South Korea’s nuclear power plants by comparing the principles and pros and cons of pressurized water reactors and boiling water reactors.   Background and Purpose of This Article Nuclear power plants, commonly referred to as “nuclear plants,” have been the subject of public interest and concern for several years. In particular, following the...

In this blog post, we’ll examine the principles and safety of pressurized water reactors, as well as the key issues surrounding the controversy over the extension of Unit 1 of the Kori Nuclear Power Plant’s operating life.   Nuclear Power and the Image of Fear in South Korea Nuclear power accounts for about 33% of South Korea’s electricity production and has played a major role in industrial...

In this blog post, I’ll explain in simple terms how NMR helps determine the order and manner in which atoms are bonded within a compound.   Why Do We Need to Know the Order of Atomic Bonds? Just like the childhood joke, “What do you get if you split an ant into three parts?”—which makes us laugh—questions about the components of matter are much more serious and important in chemistry. If...

In this blog post, we’ll explain the structure and operating principles of gas springs, as well as typical examples of their use in everyday life, in simple terms.   Many readers have probably been fascinated by the height-adjustable chairs in their father’s office or at school. If you recall sitting in a chair as a child and pulling a lever to lower or raise it, you might have wondered why...

In this blog post, we’ll explain the role and key factors of the catalytic converter, which effectively purifies exhaust gases in gasoline-powered vehicles.   The cold is receding, and the spirit of spring is gradually growing stronger. While spring is generally associated with positive imagery as a time of new beginnings, South Korea faces an unwelcome visitor: yellow dust. This uninvited...

In this blog post, we’ll focus on leading VR devices like the Oculus Rift to examine advancements in visual and motion technologies, as well as the challenges that still lie ahead.   The Imagination and Reality of Virtual Reality “What if I could actually step into a game?” This is a question anyone who has ever played a game has probably asked themselves at least once. This desire may be...

In this blog post, we’ll explore the risks and questions that a perfect virtual world—like the one in ‘The Matrix’—poses to our society, including mental confusion, the collapse of morality, and the breakdown of human relationships.   The Rise of Virtual Reality and Our Response 3, 2, 1… Whoooosh— “Kwa-ka-ka-ka-ka!!!” “Dum-dum-dum-dum-dum, ping, pock, eek!” Expressions like...

In this blog post, we’ll summarize the definition, principles, history, major applications, limitations, and future prospects of virtual reality.   What is virtual reality? Virtual reality is a technology that creates imaginary scenarios to stimulate the user’s five senses, providing an experience that is nearly indistinguishable from reality while transcending temporal and spatial...
