Recently, World Health Organization predicted a near end of COVID-19 pandemic. However, the prediction should be interpreted cautiously. Due to SARS-CoV-2 continuous mutation-evolve, limited durability of infection-acquired protection in individuals with hybrid immunity, and the effects of long COVID-19 or Post-COVID-19 syndrome, COVID-19 may continue to be a worldwide threat. Alternative therapeutics are incorporated into some countries’ health guidelines for COVID-19. Qiannan herbal, an ancient medical book of Yi Nationality in China, recorded that grapes and turmeric were often used to treat respiratory diseases. Curcumin and resveratrol are the primary bioactive compounds in turmeric and grapes, respectively. The clinical trials confirmed that curcumin or resveratrol supplementation could cause moderate or marked improvements in COVID-19 patients. Exploring the potential mechanisms is of great significance. This study found that curcumin and resveratrol could effectively inhibit SARS-CoV-23CLpro activity and spike protein-mediated cell entry. Curcumin and resveratrol could significantly alleviate spike protein-mediated cytokine storm via inhibiting over-activation of NFKB, and effectively ameliorate spike protein-mediated oxidative stress through scavenging ROS and enhancing function of antioxidation system. The combined treatment showed a better effect than alone treatment. Therefore, curcumin and resveratrol could inhibit SARS-CoV-23C-like proteinase activity and Spike protein-mediated cell entry, cytokine storm, and oxidative stress.

“…In addition, most developing countries implemented comprehensive entry and exit controls to contain the spread of the virus. Consequently, this led to a complete halt in business operations at construction sites and offices, resulting in significant economic losses [11,69]. The ROK had no enforced lockdown measures, and the construction sites and offices were consistently operated remotely.…”

From cost and management perspectives, the sudden outbreak of COVID-19 and the subsequent countermeasures adversely affected labor-intensive construction companies owing to the restrictive guidelines. Following a systematic literature review, this study developed a theoretical framework to assess the impacts of COVID-19 and its countermeasures on construction sites. Based on a developed framework reflecting abroad cases, we explored the Republic of Korea (ROK) situation. Questionnaires were utilized to detect this impact, and were then analyzed using the relative importance index. Through interviews with site managers in the ROK, combined with text-mining and network analysis, this study aimed to pinpoint effective countermeasures and validate the framework. Results revealed that despite policy changes, construction sites in the ROK were not seriously affected during the COVID-19 pandemic. However, while foreign investment remained steady owing to robust financial contracts, labor shortages and cooperative challenges hindered productivity. Additionally, beyond telecommuting and inspections, changing hygiene regulations prompted the adoption of smart technologies. Further, site managers requested the optimization of worker management and smart systems with governance, hygiene, and quarantine policies. Although impacts from other countries have been studied, the experiences of industries in the ROK remain unanalyzed. In addition, the existing literature has only examined the economic viability of the construction industry; therefore, this study assessed the impacts and countermeasures of COVID-19 from the perspective of managers using a unified theoretical framework.

“…With the development of safety science, safety management is viewed as a multi-level non-linear control problem [15]. Accordingly, the accumulation of safety management defects (shortages, design deviations, or poor implementation) at the organizational level is considered to be the root cause of the degradation of safety performance and contributes to the occurrence of safety-related incidents [13,19]. From an accident causation perspective, according to the traditional linear accident models (the domino model developed by Heinrich [20], Reason's Swiss Cheese model [21], the ARAMIS methodology [22], etc.…”

Assessing the Degradation of Safety Management Performance in Large Construction Projects: An Investigation and Decision Model Based on Complex Network Modeling

et al. 2023

Modern safety control theory suggests that the accumulation of safety management defects at the organizational level can lead to a degradation in the overall safety management performance. This problem is exacerbated by the increasing complexity of safety management in large construction projects. The theoretical frameworks proposed by existing studies can provide generalized guidance for identifying safety management defects, but they are not flexible enough to address the complexity of a safety management system (SMS) in specific large construction projects. This study proposed an investigation and decision model based on a complex network model of SMSs. The main purpose was to accurately assess the degradation of safety management performance through the comprehensive identification of safety management defects for large construction projects. The functional components and their interactions in SMSs were graphically represented in a complex network using the fuzzy DEMATEL technique. Based on this, deep-seated safety management defects were identified by tracing the path of influence between the functional components and their roots. Furthermore, the results of this identification were used to support the assessment of the degradation of the safety performance of the overall SMS. The proposed model was verified with a large-scale wastewater treatment plant construction project in Lanzhou City, China. The degradation of the functional components could be presented in a complex visual network map to facilitate an understanding of the weak points or risk-sensitive areas throughout the SMS. Especially in the case of false safety perceptions, deep-seated safety management defects can be identified in time to prevent a sudden collapse of the SMS through early warnings. In addition, it also facilitates timely short-term improvement strategies and systematic long-term improvement strategies for long-term sustainability and increased resilience.
