In this blog post, we’ll examine the free-riding problem that arises in group projects from the perspectives of group selection and altruistic behavior, and consider evaluation methods to reduce free-riding as well as the reasons why we should live altruistically.   When working on group projects, it is not uncommon for students to shirk their assigned tasks and pass the burden onto other...

In this blog post, I’ll examine the causes of free-riding in group projects and ways to prevent it, and further explore why we should live ethically from the perspectives of altruistic behavior and reciprocity.   What are the types and causes of free-riding? Have you recently seen a post on social media with a title like, “Looking for free-rider 000, who vanished on the day of the group...

In this blog post, based on ‘The Emergence of the Altruistic Human’, I’ll examine ways to prevent free-riding and the reasons behind them, and ultimately reflect on why humans should live righteously.   Every student experiences group projects at least once in their life. However, most students who have participated in group projects have likely experienced frustration and been...

In this blog post, we’ll examine the causes of free-riding in group projects and ways to prevent it. Furthermore, we’ll reflect on why we should live with integrity and what criteria we should use to judge what constitutes right and wrong behavior.   There’s a phrase that sends shivers down the spine of any ordinary person who is currently in college or has graduated. The four characters...

In this blog post, we will examine the basic structure and operating principles of unmanned vehicles and autonomous vehicles, and explore the possibility of multiple unmanned vehicles sharing information and driving cooperatively—safely and efficiently—by utilizing swarm intelligence inspired by the swarming behavior of animals.   The Evolution of Unmanned Vehicles and Autonomous Driving...

In this blog post, we’ll examine the convenience and safety benefits that the commercialization of self-driving cars will bring, as well as the issues surrounding jobs and liability, and explore the reasons for supporting their commercialization.   How far has the commercialization of self-driving cars progressed? Thanks to recent advances in science and technology, technologies that operate...

In this blog post, we’ll examine the operating principles and safety features of self-driving cars, as well as the risks to cybersecurity, and explore just how far autonomous driving technology has actually advanced.   A rather special car has made an appearance at Seoul National University, where countless vehicles come and go every day. This is the story of SNUBer 2, which navigates the...

In this blog post, we’ll examine the relationship between a car’s displacement and engine performance, explore the principles, advantages, and disadvantages of turbochargers—which enable even small-displacement engines to deliver strong power and output—and look at how turbocharged engines are being utilized in the automotive industry today.   In 2012, Hyundai Motor Company launched the...

In this blog post, we’ll explore the principles behind heat pump HVAC systems—which perform both cooling and heating with a single unit—the refrigerant circulation process, and the advantages and limitations of heat pumps.   Heat Pumps: One Unit, Two Functions Throughout our lives, people seek out and strive to create objects or tools that can perform multiple different functions at once...

In this blog post, we’ll explore whether tiny robots capable of moving through the human body for therapeutic purposes are actually feasible, focusing on how micro-robots are built, how they operate, and the physical phenomena that play a crucial role in the microscopic world.   Were robots floating inside the body just science fiction? When we think of science fiction, many things come to...
