In this blog post, we’ll explore whether fusion power can establish itself as a future energy source by examining everything from the principles of nuclear fusion—the process by which the Sun generates energy—to the characteristics of magnetic confinement and inertial confinement methods, as well as recent achievements in fusion research and the challenges that remain.   What is the Sun’s...

In this blog post, we’ll take a detailed look at the subsea drilling process—from drilling wells to extract oil and natural gas buried beneath the seabed to protecting those wells using techniques such as wellbore lining, casing, and cementing, and finally connecting them to production facilities.   In modern society, oil remains a vital energy resource and industrial raw material. From fuel...

In this blog post, we’ll explore everything from the basic oil and gas production processes at offshore plants to why simulation is crucial in offshore plant design, and how to optimize using Aspen HYSYS.   Offshore resources such as oil and natural gas lie buried deep beneath the seabed. Various offshore facilities are used to explore, drill, produce, and process these resources. Offshore...

In this blog post, we’ll explore the evolution of aircraft propulsion systems—from humanity’s longing for flight to piston engines, propellers, turbojets, turboprops, turbofans, and ramjets—and examine how this progression led to space propulsion technology.   The fact that people have constantly strived to reach the sky can even be found in Greek mythology. The story of Icarus, who flew...

In this blog post, we’ll explore the emergence and development of synthetic biology—which aims to engineer and create living organisms based on a physical and chemical understanding of the nature of life—and examine how concepts of circuit and system design from electrical engineering are converging with the life sciences.   Suppose we are conducting a fruit fly cloning experiment in a...

In this blog post, we’ll explore how humans perceive color and how the molecular structure and color of pigments change in response to pH changes, using the example of this fascinating ice cream that changes color as you lick it or as it melts.   On a peaceful Sunday afternoon, while enjoying a stroll in a quiet park under the warm sunshine, you stopped by a nearby ice cream shop and bought...

In this blog post, we’ll examine the hydrodynamic principles behind the high-tech swimsuits that shook the world of swimming, how they helped athletes improve their times, and why FINA decided to regulate them.   At the World Aquatics Championships held in Rome, a staggering 43 world records were set. The swimming world witnessed a wave of record-breaking performances, including a new world...

In this blog post, we’ll examine how mobile phone subsidies in South Korea affect consumers’ device purchase costs and service fees, and explore how to balance consumer protection and market competition in today’s South Korean mobile communications market, now that the strict subsidy regulations of the past have been abolished.   Why Do Prices Vary for the Same Cell Phone? When looking to...

In this blog post, I’d like to examine the significance of mathematics in daily life and the advancement of science and technology, and reflect on the challenges currently facing mathematics education as well as the direction we should take moving forward.   After graduating from high school, I thought my days with math were over, but when I arrived at college and saw that nearly half of my...

In this blog post, we’ll examine the long-standing issues of device subsidies and distribution structures in the South Korean smartphone market, trace the changes that led to the current subsidy competition system—from the introduction to the repeal of the Mobile Device Distribution Act—and discuss what consumers need to know to make informed smartphone purchases.   The sight of nearly...
