Abstract objective This work investigates how reinforcement learning and deep learning models can facilitate the near-optimal redistribution of medical equipment in order to bolster public health responses to future crises similar to the COVID-19 pandemic. materials and methods The system presented is simulated with disease impact statistics from the Institute of Health Metrics (IHME), Center for Disease Control, and Census Bureau[1, 2, 3]. We present a robust pipeline for data preprocessing, future demand inference, and a redistribution algorithm that can be adopted across broad scales and applications. results The reinforcement learning redistribution algorithm demonstrates performance optimality ranging from 93-95%. Performance improves consistently with the number of random states participating in exchange, demonstrating average shortage reductions of 78.74% (± 30.8) in simulations with 5 states to 93.50% (± 0.003) with 50 states. conclusion These findings bolster confidence that reinforcement learning techniques can reliably guide resource allocation for future public health emergencies.

BACKGROUND Given the permeation of social media throughout society, rumors spread faster than ever before, which significantly complicates government responses to public health emergencies such as the COVID-19 pandemic. OBJECTIVE We aimed to examine the characteristics and propagation of rumors during the early months of the COVID-19 pandemic in China and evaluated the effectiveness of health authorities’ release of correction announcements. METHODS We retrieved rumors widely circulating on social media in China during the early stages of the COVID-19 pandemic and assessed the effectiveness of official government clarifications and popular science articles refuting those rumors. RESULTS We show that the number of rumors related to the COVID-19 pandemic fluctuated widely in China between December 1, 2019 and April 15, 2020. Rumors mainly occurred in 3 provinces: Hubei, Zhejiang, and Guangxi. Personal social media accounts constituted the major source of media reports of the 4 most widely distributed rumors (the novel coronavirus can be prevented with “Shuanghuanglian”: 7648/10,664, 71.7%; the novel coronavirus is the SARS coronavirus: 14,696/15,902, 92.4%; medical supplies intended for assisting Hubei were detained by the local government: 3911/3943, 99.2%; asymptomatically infected persons were regarded as diagnosed COVID-19 patients with symptoms in official counts: 322/323, 99.7%). The number of rumors circulating was positively associated with the severity of the COVID-19 epidemic (ρ=0.88, 95% CI 0.81-0.93). The release of correction articles was associated with a substantial decrease in the proportion of rumor reports compared to accurate reports. The proportions of negative sentiments appearing among comments by citizens in response to media articles disseminating rumors and disseminating correct information differ insignificantly (both correct reports: χ<sub>1</sub><sup>2</sup>=0.315, <i>P</i>=.58; both rumors: χ<sub>1</sub><sup>2</sup>=0.025, <i>P</i>=.88; first rumor and last correct report: χ<sub>1</sub><sup>2</sup>=1.287, <i>P</i>=.26; first correct report and last rumor: χ<sub>1</sub><sup>2</sup>=0.033, <i>P</i>=.86). CONCLUSIONS Our results highlight the importance and urgency of monitoring and correcting false or misleading reports on websites and personal social media accounts. The circulation of rumors can influence public health, and government bodies should establish guidelines to monitor and mitigate the negative impact of such rumors.

Masjid adalah pusat kegiatan kaum muslimin. Berbagai permasalahan seperti politik, ekonomi, sosial masyarakat, dan peradilan dibahas dan diselesaikan bersama-sama di masjid. Karena fungsi masjid sejatinya adalah untuk menyatukan, melayani, dan mensejahterakan umat. Salah satu yang harus diperhatikan oleh masjid adalah sosial masyarakat, yang membahas mengenai kesejahteraan dan kesehatan masyarakat. Maka masjid sudah seharusnya memiliki sistem yang bergerak di bidang itu, agar fungsi masjid bisa terealisasikan. Penelitian ini membahas sistem pelayanan kesehatan yang ada di Poliklinik Masjid Al-Falah Surabaya. Tujuan yang ingin dicapai dalam penelitian ini adalah untuk mengetahui bagaimana sistem pelayanan kesehatan yang ada di Poliklinik Masjid Al-Falah Surabaya serta faktor pendukung dan penghambatnya. Penelitian ini menggunakan metode kualitatif deskriptif. Dari hasil penelitian ini, disimpulkan bahwa sistem pelayanan kesehatan yang diberikan oleh Poliklinik Masjid Al-Falah Surabaya kepada masyarakat dan jama’ah secara keseluruhan sudah baik. Faktor-faktor yang mendukung yaitu adanya dokter-dokter spesialis, peralatan medis yang cukup lengkap, serta tersedianya obat-obatan. Sedangkan faktor penghambatnya adalah ruang antrian yang kurang luas. A mosque is the hub of Muslim activities. Problems such as politics, economics, social communities, and justice were discussed and settled together in the mosque. For the purpose of mosques is for the unification, service, and welfare of the masses. One of the concerns of mosques is the social community, which talks about the welfare and public health. Then mosques should have a system of movement in that area, for the function of mosques to be realized. The study discussed the health care system found in polyiclinic of the Al-Falah Surabaya Mosque. The goal of this study is to find out how the health-care system in the polyiclinic of the al-falah mosque there is surabaya and its supporting factors and constrainting. The study employs descriptive qualitative methods. From the study, it was concluded that the health care system given by the polyiclinic of the Al-Falah Mosque Surabaya to the community and the jama 'ah overall was good. Supportive factors include doctors, adequate medical equipment, and medical supplies. The retard factor was a small queues

AbstractAt the early stage of public health emergencies, when the conventional medical reserves prepared are insufficient, and productivity could temporarily not meet the surge in demand, donations can be used to cover excess demand for medical supplies to a large extent. This paper explicitly considers the allocation problem of limited medical reserves during a public health emergency, incorporating uncertainty in demand and donated supplies and the priorities of health care centers. The problem is formulated as a two-stage stochastic program that regards the donated supplies as an efficient recourse action, aiming to minimize the total losses. The optimal allocation strategy of limited medical reserves and donations is obtained by solving the model using Gurobi solver. Finally, the effectiveness of the proposed approach is verified by a series of computational results, which show that the solutions of our method not only benefit the emergency demand fulfill rate but reduce the total losses as well.
