In this blog post, we’ll explore what cashmere—a quintessential luxury winter fabric—actually is, examine its functionality and characteristics based on blend ratios, and cover its main uses and proper care.   What Kind of Fiber Is Cashmere? Cashmere fiber, derived from the fur of the cashmere goat, is one of the premier materials for alleviating the hardships of a cold winter. While many...

In this blog post, we’ll compare a smartphone’s “Favorites” feature to a computer’s cache to explore the principle of keeping frequently used data close at hand, as well as the structure and operation of a cache.   When using a smartphone, placing frequently used apps—such as KakaoTalk or the phone app—in an easily accessible location reduces the time it takes to find them, making them more...

In this blog post, we’ll examine the causes of free-riding in group projects and ways to address it. We’ll then extend this discussion to social relationships to explore whether it’s necessary to live righteously even in situations where we aren’t directly harming others.   A long time ago, a drama based on the webtoon “Cheese in the Trap” aired. In it, there is a scene where group members...

In this blog post, we’ll explore the evolution of biomimicry—the process of creating new technologies by mimicking nature’s structures, functions, and the principles behind natural phenomena—and examine some representative examples.   Biomimicry: Learning from Nature There is nothing new under the sun. This saying perfectly captures the essence of biomimicry. Humans have invented countless...

In this blog post, as we read ‘You Will Never Return to Your Hometown’, we’ll explore the process by which a man transforms into a writer, the change he undergoes after breaking with the past to gaze upon a broader world, and the profound questions the work raises about humanity and society.   Why We Read Thomas Wolfe’s Life and Works Together While reading ‘You Will Never...

In this blog post, I’ll examine free-riding from the perspective of the public goods game and reflect on why we should live righteously in situations where individual interests conflict with group interests.   Do you think you’re living a righteous life? Of course, few people would be confident enough to say they live a perfectly righteous life. However, most people would likely answer that...

In this blog post, I’ll examine the free-rider problem that arises in group projects from the perspective of the repetition and reciprocity hypotheses, and based on this, reflect on altruistic behavior and the meaning of a righteous life.   While there are countless sources of stress for college students, group projects are arguably the most notorious of them all. Although group projects are...

In this blog post, I’ll examine free-riding as a prime example of selfish behavior and discuss ways to address it through both coercive sanctions and voluntary incentives, while reflecting on why we should live righteously.   From a young age, we are taught that we must live righteously. Most people who consider themselves moral accept this as a given, but is there truly a reason why humans...

In this blog post, I’ll examine the free-riding problem that arises in college group projects from the perspective of repeated reciprocity, and reflect on what it means for individuals and the community when we help and cooperate with one another.   Unlike in middle and high school, once you enter college and begin working on assignments, you’ll notice that group projects are a common part...

In this blog post, I’d like to explore methods for preventing free-riding and, from evolutionary and psychological perspectives, consider why humans should live righteously.   Is there a reason to live righteously? This question has long been a subject of debate among philosophers. As seen in the case of Lee Su-hyun, who lost his life while saving someone on the subway, this question...
