Social media has become an essential tool of the information age, connecting people around the world and having a positive impact, but it also has negative effects, such as personal information leakage and loss of relationships.   In his book The Third Wave, Alvin Toffler predicted the first wave of the agricultural revolution, the second wave of the industrial revolution, and the third wave...

The browning of apples and bread are both caused by the same browning reaction, but the mechanisms are different. Apples turn brown from the reaction with oxygen due to enzymatic browning, while bread turns yellow due to the chemical reaction of sugars and proteins in the Maillard reaction, a non-enzymatic browning process.   If you leave an apple out at room temperature for a while...

This article explains the difference between electricity as energy and electricity as a signal, which is what electrical engineering deals with, and introduces the applications of electrical engineering and how the technologies it has developed have impacted our lives and industries, most notably MRI technology.   When you think of the Department of Electrical Engineering, what do you think...

This article covers the role of frequencies and their importance in communications technology. It explains the concept of frequency and its impact on communications, discussing how it is used, especially in wireless communications, and how to efficiently manage the limited frequency resource.   Humans have long sought to overcome temporal and spatial limitations to communicate information...

Noise has become a big issue in the modern world, causing problems such as poor concentration and noise-induced hearing loss. While there are many efforts to reduce noise, it’s not always best to eliminate it completely, especially when noise can be an important factor in evaluating the performance of a machine, it can be more effective to control it properly. Noise engineering is showing...

Uniqlo, Zara, and H&M have grown into global SPA brands by optimizing the production-to-sale process through supply chain management (SCM). Their unique SCM strategies allow them to reduce costs, respond quickly to the latest trends, and remain competitive in the global marketplace.   The total sales of the “Big 3” SPA brands, including Uniqlo, ZARA, and H&M, are growing every year...

While over-packaging is often criticized as a way for companies to maximize profits, it can also be seen as a necessary change to meet the aesthetic demands and design-consciousness of modern consumers. In addition to the functional aspects of a product, its aesthetic design is also an important purchase decision factor, especially for younger consumers.   Nowadays, many products sold in...

Graphene is a dream material that could be used in a wide range of technologies, from transparent and thin touchscreens to strong body armor and high-efficiency solar cells. However, commercialization is still a long way off due to technical and economic limitations of mass production, but research is underway around the world to overcome them.   If you’re a fan of science fiction...

The scientific and technological advances of the Fourth Industrial Revolution have brought many benefits to humanity, but they have also created threats, such as nuclear weapons. It is necessary to discuss how scientists should be socially responsible and pursue beneficial values when selecting research topics.   As we enter the Fourth Industrial Revolution, advances in science and...

Aerogel is a new material that is lightweight, soundproof, and insulating, and is playing a revolutionary role in science and technology as well as everyday life. It has a wide range of applications, including gold that floats on water, and its uses range from space dust collection to high-temperature insulation.
