NEXUS is a crisis management app that provides peace of mind to international students and their parents. It is designed to keep international students safe and to help schools effectively support international students. This app addresses the various risks that international students face and helps schools quickly and accurately confirm the safety of international students. It also has a function that provides useful information when international students encounter illness or accidents, and guides them on how to contact the appropriate medical institution. Additionally, OSSMA services provide pre-travel crisis prevention education and support the establishment and operation of an accident response headquarters in the event of a serious accident. Through this app, we provide both international students and their parents with a sense of security and fully support the school's international program management. By centrally managing study abroad safety and support, you will be able to have a more fulfilling study abroad experience.
