This project is mainly based on a retrospective monographic database. Taiwanese and Thai students will jointly analyze and study cross-national comparative health big data, hoping to further understand the health differences and health services between the two sides and to communicate with each other. The project team is also working to collect comparable data for the two countries. The important task of this project is to gather the health data of the two countries, and give full play to the advantages of universal coverage and comprehensive coverage of various life information, and even consider incorporating various forms of data (electronic health records (EHR), genomics, images, lifestyle, mobile and wearable data), etc. Finally, the data will be organized and analyzed to achieve the FAIR data principles - Findability, Accessibility and Accessibility.
