초록

콜드체인의 마지막 단계인 백신전달 과정에서 대부분 얼음을 넣은 단열컨테이너로 온도를 조절하며, 백신의 온도 조절이 적절하지 않아 낭비되는 백신의 양이 상당하다. 예방접종을 관리하고 운영하는데 온도 데이터가 중요하며, 본 연구에서는 실시간 백신전달 모니터링 시스템을 개발하였다. 휴대용 백신 냉장고의 온도, 위치 및 전력 소비 데이터를 수집하기 위해 문자(Short Message Service) 통신 방법을 사용하였고, 한국과 탄자니아(아루샤 및 킬리만자로 지역)에서 시스템을 테스트하였다. 개발된 백신 냉장고는 문자통신을 통해 데이터 손실없이 실시간으로 백신상태를 모니터링을 할 수 있었다. 백신의 상태 및 데이터는 클라우드 서버를 통해 웹 기반 유저 인터페이스에서 확인할 수 있었다.

In the process of vaccine delivery and vaccination, temperature is mostly controlled by an insulated containers containing ice. Moreover, amount of wasted vaccine is significant because the temperature of the vaccine is not properly controlled. A core challenge of vaccination is temperature data monitoring, since it is critical for managing and operating strategical vaccination by health organizations. In this research, a real-time monitoring vaccine carrier system was developed. Temperature, location, and power consumption data of the vaccine carrier were monitored and working performances of the vaccine carrier were tested in both Korea and Tanzania (Arusha and Kilimanjaro regions). For both places, Short Message Service (SMS) communication method was used to send information of the carrier's status. As a result, the monitoring system was able to transmit and receive real-time data of the vaccine carrier status while the vaccine carrier was tested. The vaccine status data can be accessed from any location through the cloud server and web-based user interface.
