This course is offered under the program of the HKUST Summer Institute for Secondary School Students by the School of Humanities and Social Science. Our life has been greatly improved by advances in science and technology, which are gradually being regarded as a proper (and sometimes the only) way to solve problems. But such advances have also raised critical issues, many of which have adverse effects on our health. In this course, students will examine the appearance of health issues as a result of technological 'advances', and what their solutions have been. It will also examine major health problems that have had a great impact on our community and their causes; and the place of science and technology in dealing with related problems. The role of technology in maintaining good public health and handing possible public health crises are also explored. Finally, this course seeks to develop students' ability to evaluate public health issues from different perspectives, taking into account scientific, historical, moral, social, ethical and cultural factors.
