  The automobile has undergone many transformations since its invention over 100 years ago, with more than 90 million vehicles produced annually using fossil fuels and electricity as energy sources. It is an important industry in South Korea, accounting for 80% of transportation and 10% of employment. However, advances such as autonomous driving technology are being made along with...

Nuclear power enables efficient electricity generation, but it also poses risks, such as the Fukushima accident. To replace it, we need to reduce our reliance on nuclear power plants by reducing energy waste, developing renewable energy, and increasing power efficiency. By building a sustainable energy supply system, we can prepare for a safer and greener future.   Remember the Fukushima...

Eugenics is the attempt to improve the quality of life by manipulating human genetic traits, and while it can be useful when limited to therapeutic purposes, unethical applications risk undermining human dignity. It is important to establish ethical standards through social consensus.   When we meet another human being, we ask them a number of questions to get to know their personality and...

Among the various predictions of the end of humanity, we explore the possibility that advances in science and technology will allow Homo sapiens to evolve into new, godlike beings. It explains how biotechnology, cyborg engineering, and non-organic engineering can overcome the limitations of Homo sapiens and transform it into a new form of being.   The end of humans, or Homo sapiens, has been...

Shipbuilding and marine engineering goes beyond the design and construction of ships to study various fields such as marine resource development, environmental protection, and disaster response, including offshore plants and structures, which play an important role in sustainable development and safety.   Shipbuilding and Marine Engineering is a major that deals with all engineering problems...

The problem of free-riders in group work undermines a sense of community and collaboration. To combat this, small groups, repetitive assignments, and a reward and punishment system based on participation are effective ways to reduce free-riders and increase the effectiveness of group work.   It has been said, ‘If you look at university group work, you can see why communism is...

  The laws of thermodynamics are the laws that govern the relationship between heat and mechanical work, and they are very relevant to our daily lives. The second law of thermodynamics, the law of increasing entropy, explains that natural phenomena occur in a direction of increasing disorder. It emphasizes the importance of conserving energy and protecting the environment, and small actions...

Homo sapiens has become the dominant species in ecosystems through cognitive, agricultural, and scientific revolutions, and has achieved unimaginable evolution through intelligent design, including biotechnology, cyborg engineering, and non-organic engineering. But their insatiable appetite and evolution without an ultimate goal warns of a possible apocalypse.   About 100,000 years ago, Homo...

The experience of scolding my younger brother in high school made me think about the nature and purpose of scolding. Whether it is for educational purposes or to relieve the emotions of the person being scolded, it makes me recognize and reflect on the difference between my own standards and those of society.   A few years ago, at this time of year, high school juniors were the so-called...

While scientific theories rely on inductive arguments based on observation, the subjectivity and imperfection of observation has a significant impact on the reliability of scientific inquiry. Repeated experiments and various methods are used to improve reliability, and science seeks more accurate and comprehensive understanding through a process of self-correction.   Unlike deduction, which...
