In this paper, to prevent accidents of school vehicles used by students, which have emerged as a continuous social problem, a boarding and leaving notification system using Bluetooth beacons is proposed. The platform structure uses Bluetooth, a smartphone, and an application, and provides real-time message reception between parents and teachers. It is not simply a system with Bluetooth capability alone, but also an IcT technology that is closely related to real life using two-way communication. The purpose is to provide user-friendly ICT technology as an integrated system for more practical effects. Two-way exchange of information between parents and teachers using cloud servers is made possible. By using this Bluetooth beacon notification system, safety accidents in student vehicles are reduced, which brings confidence from traffic accidents to schoolchildren of parents and teachers. Therefore, it is expected that parents and teachers are expected to improve their mental stability and quality of life from traffic accidents.

최근 증가하고 있는 자유개별여행자들의 경우 항공권, 숙박 등의 여행상품을 개별로 구매하고 여행지에서 지역 여행정보를 통해 여행상품을 구매한다. 일반적인 여행 앱에서는 여행자에게 일괄적으로 관광 상품 메시지를 전송한다. 하지만 해당 여행지에 대한 정보 메시지를 여행 시간대별로 받는다면 여행자는 그 정보를 토대로 좀 더 다양한 여행을 즐길 수 있으며, 해당 지역의 여행 상품을 판매하는 판매자의 경우 효과적인 홍보 마케팅이 이루어질 것으로 사료된다. 따라서 본 연구에서는 해당 여행지를 여행하고 있는 여행자에게 스케줄링된 여행정보를 주기적으로 전송할 수 있는 FCM기반의 푸시서비스 개발을 목적으로 하였다.

The Internet of Things(IoT) is one of the key technologies in the Fourth Industrial Revolution. The IoT is a system that acquires information from various sensors and provides meaningful information to users. The method of obtaining information from sensor is using WIFI, Bluetooth and Server. is not accessible to external users because of different type of networks or local area communication. For this reason, there is a problem that external user cannot receive notification in regard to sensor information. In this paper, we want to establish a cloud message environment using Google's FCM(Firebase Cloud Messaging) and find out through experiments how users can receive notifications even if they are outside.
