ABSTRACT
Owing to the COVID-19 pandemic, remote work has been widely adopted as one of the safe management measures at workplaces. The rapid advancement in communications technology has enabled work to still be delivered efficiently and effectively through virtually. With remote work being a norm in workplace management, housing estates are expected to remain largely occupied during office hours. For residents who are staying near to an aerodrome, their work concentration may be affected by aircraft noise pollution. Prolonged aircraft noise exposure could have negative effects in the built environment. Therefore, it is timely to emphasise the importance of aircraft noise prediction and management at the outset of urban planning. This paper presents the current development of an aircraft noise prediction algorithm, which will eventually serve as a tool to study the effects and control measures of aircraft noise. © International Institute of Acoustics and Vibration (IIAV), 2022.
ABSTRACT
During the period of COVID-19, it is still inevitable for people to contact with each other based on the consideration of economic development. Therefore, the health management measures for staying in the hotel have become an important part of epidemic prevention. As we all know, ultraviolet (UV) light is an effective disinfection and sterilization method, which has been widely used in many applications. In this paper, a hotel anti-epidemic management system is proposed to disinfect the used rooms by using UV LEDs through WiFi communication with the front desk computer, and therefore it can protect quests from virus infection. © 2022 IEEE.
ABSTRACT
The objective of this study is to present a preventive measures pertaining to COVID-19 in swimming pools and hot springs in Europe, Canada, United States, and Colombia. After the start of pandemic, all swimming pools, beaches, and hot springs in Colombia were closed. Currently, official management plans have yet to be presented for the opening of hot springs and swimming pools. However, the European Association of Water Parks presents a two-stage reopening plan for public recreation centres, while countries such as United States, Australia, Canada, China, and Austria follow similar measures. Among the most representative management measures mandated to prevent the spread of the virus, medical authorities from a variety of governments have collectively recommended the following: i) maintaining rigorous social distancing, ii) cleaning or disinfection of surfaces and common areas routinly, iii) maintaining healthy environments and most importantly, iv) personal care (ie. if not feeling well, stay home and do not put others at risk). © 2021 IEEE.
ABSTRACT
Medical wastewater originating from hospitals specializing in infectious diseases pose a major risk to human and environmental health during pandemics. However, there have been few systematic studies on the management of this type of wastewater management. The function of the Huoshenshan Hospital as a designated emergency field hospital for the treatment of COVID-19 has provided lessons for the management measures of medical wastewater, mainly including: (1) Modern information technology, management schemes, and related standard systems provided the legislative foundation for emergency management of medical wastewater. (2) The three-tier prevention and control medical wastewater management system ensured the discharged wastewater met water quality standards, especially for the leak-proof sealed collection system of the first tier, and the biological and chemical treatment technology of the second tier. (3) The establishment of an effective three-tier medical wastewater quality monitoring accountability system. This system was particularly relevant for ensuring continuous data monitoring and dynamic analysis of characteristic indicators. (4) Information disclosure by government and public supervision promoted successful implementation of medical wastewater management and control measures. Public questionnaires (n = 212) further confirmed the effectiveness of information disclosure. The results of this study can act as methodological reference for the emergency management of wastewater in designated infectious disease hospitals under similar situations.
