The main purpose of this academic project is to build a new approach to “security,” thruough a variety of perspectives. Given the development of artificial intelligence (AI), drone technology and big data science, our conception of security is undergoing a major change. At the same time, the cross-domain and multi-domain nature of security is also becoming more evident, encompassing the nuclear, conventional, space and cyber domains. How we can build a bridge bwtween the traditional and emerging areas of security studies is also something we would like to explore in this project.
