After the start of the new semester, I undertook the task of teaching a course “Human Factors Engineering”. In fact, I taught it twice a few years ago, but I didn’t continue yet. This course is offered as an elective course for the students in related majors of business.
In Chapter 1 of Introduction, when introducing the development process of Human Factors Engineering in China, it was mentioned that Tsinghua University opened the course of industrial psychology in 1930. Chen Li published “Introduction to Industrial Psychology” in 1935, which was the earliest book introducing industrial psychology in China. Chen Li was the founder of Chinese industrial psychology, who was once served as the principal of my alma mater, the originator of the Department of Psychology, and an old gentleman we respect very much. He had been engaged in industrial psychology since the Republic of China. Researching and carrying out investigations and studies in various factories showed his patriotism and professionalism. Under the active promotion of the older generation of industrial psychology researchers, Human Factors Engineering discipline in China had been developed rapidly. In 1989, the Chinese Ergonomics Society was established, and in 1991 it became a full member of the International Ergonomics Association. In Chapter 3 of Working Environment and Color, when introducing the basic heat balance equation of the human body, it explains the importance of the micro-climate cooling system to workers in high temperature and high humidity environment. They need such a system in the enclosed protective clothing. Its main function is to absorb the thermal load of the human body, to maintain a constant body core temperature, to reduce thermal damage, to improve human working efficiency in high-heat environment, and to extend working hours, such as a space suit specially designed for astronauts. However, in the battle against COVID-19 this year, the majority of front-line medical staff wore enclosed protective clothing for a long time in the same high temperature and humidity environment, but there was no ventilation and cooling system to improve the microclimate environment in their clothes. They had no complaints and had no hesitation, which showed their patriotism and professionalism.
