Mechanical engineering lectures are based on physics, chemistry, and mathematics. The lectures are deepened into contents suitable for each major subject by utilizing basic knowledge of science-based students. However, professors also have difficulty because many students are difficult to access at first, and many concepts are not available before they enter college. In order to overcome the difficulties in the class, the concept of mechanical engineering is explained in connection with various humanities and social issues and introduced to the students who applied for the first time to apply the humanistic sensitivity based introduction to approach the unfamiliar concept more intimately. For example, it is possible to explain the concepts the appear in mechanics and design courses in elation to literature, philosophy, and law in analogy with the issues that arise in our daily lives.
