The curriculum designed in accordance with the concept of a 3D matrix covers area-specific training (longitude), issues on health and welfare policies (latitude), and the target populations. The training includes both quantitative and qualitative studies. The quantitative studies cover epidemiology and statistics that allow the students to conduct empirical investigations and review hypotheses systematically. The qualitative study provides students to observe and understand various policies and issues on health and welfare in detail, to apply them to studies on the disadvantaged groups, to reflect the real needs of the target population from their viewpoint, and to make constructive recommendations and introspections on health and welfare policies.
