This article explains the scientific principles and supercritical fluid processes that allow decaffeinated coffee to retain its flavor without the stimulus of caffeine. It also explores the potential for this technology to be used in a variety of food processing and environmental applications beyond coffee.   On my way home from class, I pass many coffee shops, including Starbucks. In the...

Money plays an important role in society and reduces transaction costs, but its value and rationale are very fragile. In the future, money will evolve into different forms as civilization and technology advance, and people will still chase after it. However, making money the purpose of life is likely to lead to unhappiness, and it is necessary to recognize values that are more important than...

The 2010 oil spill in the U.S. Gulf of Mexico was a combination of technical flaws in the oil drilling process and a lack of worker safety awareness that led to a massive environmental disaster. Understanding the dangers of oil drilling and the importance of preventing accidents is key.   On April 20, 2010, a major oil rig explosion occurred in the Gulf of Mexico in the United States.

Advances in cancer treatment are evolving from surgery and chemotherapy to immunotherapy. Antitumor immunotherapy using immune surveillance and CTLs is gaining attention as an innovative way to selectively eliminate cancer cells with minimal damage to normal cells.   The fear of cancer and efforts to overcome it have been a constant in human history, both in the East and the West. Cancer...

The Leaning Tower of Pisa tilted due to soft ground, but modern geotechnical engineering techniques were used to reduce the tilt and stabilize it. Lessons learned from this process have been incorporated into modern architecture, leading to innovative structures such as intentionally tilted buildings and skyscrapers.   The Leaning Tower of Pisa is a structure located in the western Italian...

Even though flutes are made of metals like gold and silver and don’t have reeds, they’re still classified as woodwind instruments. This is because an instrument’s classification is determined not only by its material, but also by the way it sounds and the characteristics of its playing. The flute is still classified as a woodwind instrument to this day because the player’s...

Metallic materials still play an important role in the automotive industry thanks to their excellent mechanical properties, which combine rigidity and ductility, and advances in materials science are making steel lighter and stronger. Dual phase steel and TWIP steel are the result of this research, and the possibilities for steel materials in the future are endless.   The materials that we...

The Department of Construction and Environmental Engineering focuses on building the infrastructure of modern society based on traditional technologies, and in doing so, conducts various research and activities to pursue sustainable development and prepare for the future.   You’ve probably heard the phrase “all roads lead to Rome” at least once. Most people who hear this phrase think...

Object-oriented programming emerged to overcome the limitations of procedural programming and uses the concepts of inheritance, encapsulation, and polymorphism to make code more reusable and secure. C++ implements these concepts through classes, templates, and more, and is both powerful and complex.   In the early days of programming after the development of computers, procedural programming...

  Hardware and software are important factors when buying a laptop for college students. In addition to considering the performance of the hardware, such as CPU, RAM, and graphics card, you should also consider the software, such as the operating system, to ensure that you get the right product for your needs. It’s efficient to choose a high-performance product for demanding tasks and...
