The risk of theft of goods is certainly an important source of negative influence in human psychology. This article focuses on the development of a scheme that, despite its low cost, acts as a smart antitheft system that achieves small property detection. Specifically, an Internet of Things (IoT)-based participatory platform was developed in order to allow asset-tracking tasks to be crowd-sourced to a community. Stolen objects are traced by using a prototype Bluetooth Low Energy (BLE)-based system, which sends signals, thus becoming a beacon. Once such an item (e.g., a bicycle) is stolen, the owner informs the authorities, which, in turn, broadcast an alert signal to activate the BLE sensor. To trace the asset with the antitheft tag, participants use their GPS-enabled smart phones to scan BLE tags through a specific smartphone client application and report the location of the asset to an operation center so that owners can locate their assets. A stolen item tracking simulator was created to support and optimize the aforementioned tracking process and to produce the best possible outcome, evaluating the impact of different parameters and strategies regarding the selection of how many and which users to activate when searching for a stolen item within a given area.

Abstract Sierra Leone is one of the least developed low-income countries (LICs), slowly recovering from the effects of a devastating civil war and an Ebola outbreak. The health care system is characterized by chronic shortage of skilled human resources, equipment, and essential medicines. The referral system is weak and vulnerable, with 75% of the country having insufficient access to essential health care. Consequently, Sierra Leone has the highest maternal and child mortality rates in the world. This manuscript describes the implementation of a National Emergency Medical Service (NEMS), a project aiming to create the first prehospital emergency medical system in the country. In 2017, a joint venture of Doctors with Africa (CUAMM), Veneto Region, and Research Center in Emergency and Disaster Medicine (CRIMEDIM) was developed to support the Ministry of Health and Sanitation (MOHS) in designing and managing the NEMS system, one of the very few structured, fully equipped, and free-of-charge prehospital service in the African continent. The NEMS design was the result of an in-depth research phase that included a preliminary assessment, literature review, and consultations with key stakeholders and managers of similar systems in other African countries. From May 27, 2019, after a timeframe of six months in which all the districts have been progressively trained and made operational, the NEMS became operative at national level. By the end of March 2020, the NEMS operation center (OC) and the 81 ambulances dispatched on the ground handled a total number of 36,814 emergency calls, 35,493 missions, and 31,036 referrals.

AbstractThe growing demand for quality in the Energy Distribution Service, both by consumers and by regulatory agencies, obliges most distribution utilities to apply technologies that can be easily implemented and produce results in a short term horizon. The telecontrol technology is an essential tool every time it is necessary to fast restore the energy supply. This technology, which is completely supervised and controlled by the system operation center, allows the fast detection of a fault at a distance and switch an equipment without the aid of the operating crew, thus reducing the time that the power supply is unavailable. The present paper describes a Telecontrol Project, incorporated in an electric energy distribution utility in Brazil and compares the results in quality improvement with others usual investment actions, such as operating and maintenance procedures, laterals protection and network reinforcement. This paper shows, analyzing the results, that to improve the reliability indexes in a short time, when the company’s economic recovery is more important, the application of remotely controlled switch is more effective.
