COVID-19 is spreading out in the world now. Passenger ships such as cruise ships are very critical in this situation. Boats’ hazardous areas need to be identified in advance and managed carefully to prevent the virus. Therefore, this paper proposes for the first time that three technologies are required to support the sustainable management of ships in the post-COVID-19 era. They are ship indoor positioning, close contact identification, and risk area calculation. Ship environment-aware indoor positioning algorithms are proposed for the first time for the moving ship environment, followed by a clustering algorithm for close contact identification. Then, the risk area is calculated using the convex hull algorithm. Finally, a sustainable management approach for ships post COVID-19 is proposed.

“…Bu teknolojiye yönelik çözümler üreten farklı girişimler bulunmaktadır [6]. İşaretçi, Bluetooth düşük enerji (Bluetooth Low Energy, BLE) teknolojisinin popüler kullanım alanlarından bir tanesi konum temelli uygulamalar olarak ortaya çıkmaktadır [7]. Genellikle tek bir Bluetooth vericisinin tek yönlü olarak ortama ilettiği ve yayın yaptığı, hesaplama özelliği olmayan, gönderdiği kendine özgü bilgi paketi ile mobil kullanıcıların cihazlarında kurulu olan uygulamalarıyla etkileşime geçerek, fiziksel çevre ile etkin haberleşme sağlayan işaretçi cihazlar, ilk olarak Apple tarafından piyasaya çıkarılmıştır.…”

Nesnelerin İnterneti tabanlı çözümler sağladığı kolaylıklar ve maliyetlerinin etkin olması nedeni ile gün geçtikçe artan kullanıma sahip olmaya başlamıştır. Özellikle son yıllarda gelişmeye başlayan akıllı şehir kavramı ile birlikte hemen hemen her alanda var olmaya başlayan bu teknolojiler yüksek hızda veri iletişimini destekleyebilmektedirler. Bu çalışmanın amacı servis araçlarının ve öğrencilerin hareketlerinin gerçek zamanlı olarak izlenmesidir. Böylelikle araca biniş ile okula varıncaya kadar geçen süre içerisinde tüm grupların bilgilendirilmesi ve öğrencilerin güvenli bir biçimde okula ulaştırılması sağlanmaktadır. Bu çalışma ile el ile yapılmakta olan tüm işlemler sistematik bir hale getirilmektedir. Bu amaç ile HM-11 Bluetooth düşük enerji modülü işaretçi cihazları, gerçek zamanlı olarak çalışabilen bir veri tabanı olan Firebase bulut platformunu, işaretçi cihazlara erişimi sağlayabilen MIT App Inventor Android mobil uygulamasını ve web uygulamasını kullanan okul servisi ve öğrenci takip sistemi sunulmaktadır.

“…Approaches to integrating the physiological information collected by the original equipment of medical institutions are proposed. For medical resources management, the hospital equipment/devices are located and tracked by the developed positioning technology [ 19 ] to solve the problem of equipment loss that occurs when medical equipment is rented. Therefore, indoor positioning for these medical devices and equipment can reduce the inconvenience of device management and improve management efficiency.…”

This paper presents a healthcare information and medical resource management platform utilizing wearable devices, physiological sensors, and an indoor positioning system (IPS). This platform provides medical healthcare information management based on the physiological information collected by wearable devices and Bluetooth data collectors. The Internet of Things (IoT) is constructed for this medical care purpose. The collected data are classified and used to monitor the status of patients in real time with a Secure MQTT mechanism. The measured physiological signals are also used for developing an IPS. When the patient is out of the safety zone, the IPS will send an alert message instantly by pushing the server to remind the caretaker, easing the caretaker’s burden and offering extra protection for the patient. The presented system also provides medical resource management with the help of IPS. The medical equipment and devices can be tracked by IPS to tackle some equipment rental problems, such as lost and found. A platform for the medical staff work coordination information exchange and transmission is also developed to expedite the maintenance of medical equipment, providing the shared medical information to healthcare and management staff in a timely and transparent manner. The presented system in this paper will finally reduce the loading of medical staff during the COVID-19 pandemic period.
