In this blog post, we explore individual assessment and the role of group leaders in preventing free-riding in college group projects and propose effective solutions. During college, students inevitably participate in group projects. Through repeated experiences with these projects, college students come to understand firsthand why communism has failed in the real world. When a group...
In this blog post, we’ll explore the principles and types of wireless power transmission technology, ways to improve charging efficiency, various real-life applications, and its future potential. The Imagination Sparked by Maglev Trains and Wireless Power Transmission Just like in a movie scene, maglev trains float in the air, completely separated from the tracks, allowing them to reach...
In this blog post, we’ll take a scientific look at the actual role and mechanism of enzymes—which are gaining attention as health supplements—as well as the myths and truths surrounding enzyme supplements. “Are enzymes really that good?” This is a common advertising slogan we often see in newspaper articles or online media. It lures consumers by raising expectations that simply taking...
In this blog post, we’ll examine the factors behind the explosive growth of mobile games from the perspectives of portability, accessibility, changes in the development environment, and touch-based controls.
