Environmental health experts need to identify problems in various environments and experience understanding and management of the areas that affect the human body and ecosystem. In developing countries, there are still several environmental health problems that have not been resolved in Korea. Since cultivation of knowledge through understanding these problems and improvement of the level of environmental health awareness are insufficient only by reading from books, it is intended to give students an opportunity to experience themselves. The main purpose of this course is to accumulate experience of identifying and improving practical environmental health problems through practice of investigating and evaluating environmental health problems occurring in developing countries.
