Goals To help people to survive in disasters, and to live longer and more healthily.Sahar Pakseresht I hold a Masters in Computer Science Engineering from Osmania University, India, and am currently working as a Core Care Engineer in the telecoms industry. My passion for connecting academic knowledge to the real world inspired me to create the idea of NAJI to save human lives in the event of disaster. NAJI means “saviour” in Persian, and if I can save the life of one person, then my mission has been successful.T: @SaharPakseresht E-: Sahar.pakseresht@gamil.com WT w NAJI NAJI is a two-part system, consisting of a bracelet and a mobile application. The bracelet marks the user’s location and vital signs in a disaster, making rescue easier, and the mobile app streams requests for assistance to emergency personnel. It functions over a range of communication systems in order to ensure that it continues to work when needed, by switching from data to phone to SMS to USSD as required.NAJI provides an alternative way to communicate in the event of damage or destruction of telecom infrastructure in a disaster. The solution is using a portable Wi-Fi base station, which can start moving in the damaged area and create a map of an area within 5 km of it. It can detect anyone who has the receiver – the bracelet.Through this plan, the aim is to review technological solutions for saving lives using body sensor networks, smartphones or even ordinary cellphones.
