The study presents the ethanol vapor sensing performance of a resistive sensor that utilizes a quaternary nanohybrid sensing layer composed of holey carbon nanohorns (CNHox), graphene oxide (GO), SnO2, and polyvinylpyrrolidone (PVP) in an equal mass ratio of 1:1:1:1 (w/w/w/w). The sensing device includes a flexible polyimide substrate and interdigital transducer (IDT)-like electrodes. The sensing film is deposited by drop-casting on the sensing structure. The morphology and composition of the sensitive film are analyzed using scanning electron microscopy (SEM), Energy Dispersive X-ray (EDX) Spectroscopy, and Raman spectroscopy. The manufactured resistive device presents good sensitivity to concentrations of alcohol vapors varying in the range of 0.008–0.16 mg/cm3. The resistance of the proposed sensing structure increases over the entire range of measured ethanol concentration. Different types of sensing mechanisms are recognized. The decrease in the hole concentration in CNHox, GO, and CNHox due to the interaction with ethanol vapors, which act as electron donors, and the swelling of the PVP are plausible and seem to be the prevalent sensing pathway. The hard–soft acid-base (HSAB) principle strengthens our analysis.

Published: February 2025

The primary aim of this study was to evaluate the spatial and temporal variation in human exposure to electromagnetic fields across different frequency bands within an urban area identified as the commercial zone of a medium-sized city. Central to this investigation was the use of an exposimeter, strategically positioned on the back of the operator and secured to the hip area via a belt, to ensure comprehensive and accurate field measurements. An initial analysis was conducted to determine the shielding coefficients of the human body, allowing for precise corrections of the electric field values used in the spatial assessment. To map power density across the study area for each frequency, kriging interpolation was applied. Furthermore, temporal variations in exposure levels were analyzed at three distinct times of day—morning business hours, afternoon business hours, and non-business hours—using robust statistical methods. The study’s innovative approach lies in the integration of GIS technology to uncover and visualize temporal patterns in exposure, particularly during periods of higher pedestrian density. This integration facilitated both the detection of temporal variations and the spatial representation of these changes, enabling rapid identification and assessment of exposure hotspots.

Published: February 2025

In response to the limitations of existing vehicle detection technologies when applied to distributed sensor networks for road traffic holographic perception, this paper proposes a vehicle information detection technology based on single-point laser ranging. The system uses two single-point laser radars with fixed angles, combined with an adaptive threshold state machine and waveform segmentation fusion, to accurately detect vehicle speed, lane position, and other parameters. Compared with traditional methods, this technology offers advantages such as richer detection dimensions, low cost, and ease of installation and maintenance, making it suitable for large-scale traffic monitoring on secondary roads, highways, and suburban roads. Experimental results show that the system achieves high accuracy and reliability in low-to-medium-traffic flow scenarios, demonstrating its potential for intelligent road traffic applications.

Published: February 2025

Rice bean is a legume that is considered to be an important source of protein; it is still poorly understood but can produce peptides with various biological activities. These peptides can be released by enzymes during gastrointestinal passage and have a physiological effect on cancer cells. Since both the type of legume and the enzyme cocktail used are crucial for the production of peptides against certain cancer cell types, the anticancer effects of Vigna umbellata isolate and hydrolysate against MDA and SiHa cells were investigated in this study. The isolate was obtained via isoelectric precipitation, and the hydrolysate was obtained via pepsin P7012 and pancreatin P1750. The anticancer activity was determined by cell viability via the MTT assay, and a Pearson correlation coefficient was calculated to determine the relationships between the anticancer activity and total phenolic compounds, and the antioxidant activity of the isolated rice bean protein and its hydrolysate. The rice bean hydrolysate had a higher concentration of phenolic compounds than the isolate does, resulting in high antioxidant activity. The inhibition of proliferation in SiHa cells and MDA cells was twofold greater when they were exposed to the hydrolysate than when they were exposed to the isolate, with the IC50 values at a concentration of 1000 μg/mL after 48 h of exposure for both MDA and SiHa cells. Rice bean protein hydrolysate is a good alternative for inhibiting the proliferation of SiHa cells and MDA cells, although further studies are needed.

Published: February 2025

This paper aims to provide small- and medium-sized enterprises (SMEs) owned by families with a simple, achievable technical methodology for the assessment of sustainable mobility alternatives, in particular, the purchase of electric vehicles (EVs) and photovoltaic (PV) systems. By adopting a comprehensive comparative analysis approach, this research aims to empower SMEs to make highly informed decisions concerning the choice of vehicles and energy systems that provide strategic and sustainable value. Based on a quantitative analysis linked to the total costs over ten years, and considering the different types of vehicles (electric, hybrid, and combustion) and the integration of PV systems, practical formulas are used to calculate the total cost of ownership (TCO), energy consumption, and CO2 emissions. The results show that adopting electric vehicles, especially those complemented by photovoltaic systems with storage for night-time charging, can significantly reduce operating costs and carbon emissions, generating economic and environmental value. This study provides an accessible and applicable approach to the context of family SMEs, facilitating the analysis and choice of mobility options based on simple and commercially available data. By focusing on value creation through informed and strategic decisions, this work offers a relevant contribution to the competitiveness and sustainability of SMEs, promoting the adoption of sustainable mobility technologies in an integrated and effective manner.

Authors: Wu Xiaoqing , Gao Qi , Li Wenqi
Published: February 2025

The growing accumulation of solid waste from consumerism and the traditional linear economy poses significant risks to environmental sustainability and human health, increasing pressure on manufacturers to design more recyclable products. Design for Recycling (DfR), a key subset of Design for X (DfX), offers a promising strategy to enhance product recyclability. However, its implementation is hindered by ambiguous definitions, insufficient data, and a lack of robust methodologies and tools. This review clarifies the concept of DfR in engineering, identifies three critical research gaps, and proposes future research directions based on 89 papers: (1) the development of a comprehensive DfR knowledge base, (2) the creation of standardized recyclability evaluation indicators, and (3) the establishment of an automated, data-driven design generation system. These advancements aim to support the automated creation of highly recyclable products by leveraging accurate data, precise evaluations and minimized human bias. This review not only highlights existing research gaps but also provides valuable insights to guide future DfR studies and the development of more effective tools and methods. Furthermore, it emphasizes that the successful implementation of DfR requires active participation and commitment from the entire industrial chain and society.
Simulation Analysis of Micro-Agent Innovation’s Impact on Regional Economy, Energy, and Carbon Emissions: A Case Study of the Beijing–Tianjin–Hebei Region Using the AGIO Model
Authors: Zhu Qianting , Xiong Pengcheng , Tang Wenwu
Published: February 2025

In the context of carbon emission reduction, innovation by micro-agents is crucial for regional sustainable development. This paper investigates how micro-agent innovation impacts the sustainable development of industries within a region. To achieve this, we construct an agent-based and input–output (AGIO) model, which combines agent-based simulation at the micro level with the input–output model at the macro level. Using this model, we focus on the Beijing–Tianjin–Hebei (BTH) region, analyzing micro-agent innovation activities and conducting scenario simulations based on three key factors: innovation strength, profitability, and employee motivation. The study examines the effects of micro-agent innovation on the economy, energy, and carbon emissions in the BTH region from 2017 to 2060. The findings indicate that, (1) in terms of economic structure, micro-agent enterprises with higher profitability stimulate faster economic growth compared to the other two factors. Additionally, the innovation strength of micro-agent enterprises has the greatest impact on the industrial structure in Beijing, while profitability most influences Tianjin, and employee motivation has the strongest effect on Hebei. (2) Regarding energy consumption and energy structure, energy consumption declines rapidly after reaching its peak, and the energy structure shifts towards relatively low-carbon sources such as natural gas and electricity. Among the three influencing factors in this study, micro-agent innovation strength has the most significant impact on energy consumption in the industrial sector, with this influence intensifying over time, while profitability has the most pronounced effect on the evolution of the energy structure. (3) Concerning carbon emissions, before the carbon peak, the profitability of micro-agent enterprises exerts the most substantial influence on emissions in the region. After the peak, the impact of innovation strength becomes more pronounced. This research enriches the existing body of knowledge on the complex interplay between micro-level innovation and macro-level sustainable development, while providing valuable insights and actionable policy recommendations for steering regional economic transformation and environmental sustainability amidst the challenges posed by carbon emission reduction.

Authors: Wang Yinhui , He Yugang , Gao Xiaodan
Published: February 2025

This article investigates the interplay between renewable energy utilization and the implementation of circular economy frameworks and its role in shaping environmental sustainability across 30 provinces in China from 2000 to 2023. When employing panel data methodologies, including fixed effects, dynamic ordinary least squares, and fully modified ordinary least squares, the results reveal that both the circular economy strategy and renewable energy utilization play significant roles in reducing CO2 emissions. Renewable energy utilization has a strong negative association with CO2 emissions, highlighting its transformative potential to decrease the reliance on fossil fuels and advance decarbonization. The circular economy strategy effectively enhances resource efficiency and minimizes waste, underscoring the efficacy of China’s Circular Economy Promotion Law in driving sustainable practices. The inclusion of control variables—industrialization, economic growth, urbanization, population density, and foreign direct investment—provides deeper insights into the diverse regional factors influencing emissions. These findings highlight the importance of implementing region-specific policy measures that integrate renewable energy transitions and the circular economy strategy to achieve environmental sustainability. While presenting robust evidence, this study acknowledges the need for future studies to overcome its limitations, such as studies exploring the function of technological advancements and the interprovincial spillover effects of policies, to further refine the strategies for sustainable development in rapidly industrializing economies.
A Two-Layer Causal Knowledge Network Construction Method Based on Quality Problem-Solving Data
Authors: Wang Yubin , Qiang Shirong , Yue Xin , Li Tao , Zhang Keyong
Published: February 2025

“Cause analysis” constitutes an indispensable component in quality management systems, serving to systematically identify the causes of quality defects, thereby enabling the development of targeted improvement strategies that concurrently address surface-level manifestations and fundamental drivers. However, relying solely on personal experience makes it challenging to conduct a comprehensive and in-depth analysis of quality problems. The reason is that, when analyzing the causes of quality problems, it is essential not only to consider the specific context in which the problems occur. This enables “specific problems” to be “specifically analyzed” for the formulation of temporary containment measures. Additionally, the context of the problem needs to be stripped. This allows for a general and in-depth analysis of the “class problem” or the causal linkages underlying the problem, thereby determining the root cause of the problem and formulating a corresponding long-term program. The analysis of the causes of quality problems exhibits “duality” characteristics. Based on this, this study proposes and constructs a two-layer causal knowledge network by leveraging the causal knowledge generated and applied in the process of quality problem solving to address the “duality” characteristic of the cause analysis of quality problems. The proposed network can assist front-line employees in analyzing the quality problems of products from diverse perspectives and overcome the challenge of relying solely on personal experience to comprehensively and profoundly analyze the causal relationships of quality problems. Our method not only contributes to enhancing the efficiency of quality problem solving but also makes a valuable contribution to the advancement of theories and methods related to quality management and knowledge management.
Quality Tourism in Thailand: Towards Sustainable Tourism or Further Wealth Concentration?
Authors: Veilleux Alexandre , Sarrasin Bruno
Published: February 2025

In its long-term vision for tourism development (2017–2036), Thailand has chosen to focus on the development of quality tourism, which is supposed to enable sustainable tourism development and a more inclusive sharing of tourism-generated revenues. However, the use of the term “quality tourism” remains conceptually unclear, and the means by which quality tourism will enable a more inclusive sharing of wealth remain ambiguous. Taking the tourist island of Phuket as a case study, we question how quality tourism has materialized on the island and how it has affected the configuration of power between large international hotel chains and local hotel operators regarding tourism development. Guided by a critical political economy framework and based on a qualitative methodology involving triangulation of data collection among official documents, semi-structured interviews, and participant observation, we argue that quality tourism in Phuket, although justified as a form of sustainable tourism, is more akin to luxury tourism. This has led to greater concentration of wealth among large hotel chains and real estate groups who have taken advantage of quality tourism-related policies to boost their portfolios at the expense of local stakeholders.

Published: February 2025

A detailed understanding of the toxic effects of organic UV filters, such as oxybenzone, on living organisms is crucial for assessing the feasibility of bioremediation methods. Due to the widespread use of oxybenzone as an ultraviolet filter in sunscreens, it has become an emerging contaminant of concern in the environment. This concern extends to fungi, which have the potential to neutralize a wide variety of xenobiotics released into the environment. The primary objective of the study was to elucidate the alterations of antioxidant profiles of the white-rot fungus Lentinula edodes in response to oxybenzone exposure. Samples with oxybenzone at a final concentration of 0.1 mg mL−1 were cultured in vitro with the mycelium of L. edodes for 14 days. The contents of the following antioxidant compounds were assessed: indole derivatives (6-methyl-D,L-tryptophan, tryptophan), ergothioneine, and phenolic acid (p-hydroxybenzoic acid), as well as lovastatin and ergosterol. The addition of oxybenzone negatively affected biomass growth, reducing it from 3.205 ± 0.4022 g to 0.5803 ± 0.1019 g. A considerable reduction in oxybenzone amounts was found in the medium after incubation (from 25 mg to 0.2993 ± 0.1934 mg). After lyophilization, the mycelium contained 1.1591 ± 0.0323 mg of oxybenzone. Additionally, eleven biotransformation products were assessed in the mycelium and medium samples using UPLC-Q ToF. After incubation, the transformation products were identified based on monoisotopic molecular mass and fragmentation spectra. The observed increase in the content of some antioxidants, e.g., ergothioneine, while reducing the content of others, such as lovastatin, suggests that the impact of xenobiotics on the antioxidant profile of in vitro cultures of L. edodes is complex. Marked alterations in biomass growth suggest a potential toxicological risk associated with oxybenzone. This study contributes to the understanding of the environmental impact of UV filters and emphasizes the need for safer alternatives.

Published: February 2025

Fish is a major source of protein in Asia–Pacific countries. Ciguatera fish poisoning (CFP), caused by consuming reef fish contaminated with ciguatoxins (CTXs), poses a significant health risk, affecting the neurological, gastrointestinal, and cardiovascular systems. Climate change and the global food trade are potentially major factors contributing to the expanding geographical range and frequency of CFP outbreaks. Therefore, the surveillance and monitoring of CTXs in fishery products are essential to safeguard food safety. In this study, liquid chromatography–high-resolution mass spectrometry (LC-HRMS) was used to screen for CTXs in wild-caught fish from the region. Analysis of two grouper fish samples from Okinawa, Japan, detected CTX-1B, a major CTX known to incur in fish from the Asia–Pacific region. Additionally, putative Indian Ocean CTXs (I-CTXs) were also identified. Further study with HRMS on wild-caught red emperor fish from Southeast Asia waters revealed low levels of I-CTXs as well. These findings underscore the urgent need for enhanced food safety measures and expansion of monitoring protocols to include I-CTXs. This research contributes to the global understanding of CTX distribution and confirms the importance of HRMS application in routine surveillance to mitigate the risks associated with ciguatera fish poisoning (CFP).

Tick-borne encephalitis virus (TBEV) is an emerging pathogen that initially causes flu-like symptoms and can progress to central nervous system (CNS) infections. Tick-borne encephalitis (TBE) is an endemic disease in southern coastal counties with regular human cases, while the causative agent, TBEV, is prevalent in ticks in most of the coastal regions of Norway. This study was aimed to understand TBEV infection status across Norway including both TBE endemic and non-endemic areas. For this, we analyzed a total of 1940 residual serum samples from 19 counties of Norway (as of 2016). The samples were initially screened by ELISA, followed by virus neutralization tests for TBEV confirmation. We found a similar TBEV seroprevalence of 1.7% in TBE endemic and 1.6% in non-endemic areas. Since TBE cases are only reported from endemic regions, our findings suggest a potential subclinical or asymptomatic infection and underdiagnosis in non-endemic areas. Notably, only 43% of the ELISA-positive samples were confirmed by virus neutralization tests indicating that not all ELISA positives are true TBEV infections. Additionally, 137 samples of patients presenting with symptoms of CNS infections from a non-endemic area were included. Of these samples, 11 ELISA-positive samples were analyzed for cross-reactivity among flaviviruses. Cross-reactivity was detected with Dengue virus, West Nile Virus, and non-specific reactions. This underscores the importance of using multiple diagnostic tests to confirm TBEV infections. None of the patients with CNS infection was found to be TBE positive, and in the whole cohort, we found a low TBEV seroprevalence of 0.7%.

Authors: Wang Na , Wang Gang , Zhang Hui , Li Xing
Published: February 2025

In this study, the effects of a submerged shell dike in front of a breakwater on dissipating broken waves were studied. The dissipation effects of different broken wave heights and the submerged shell dike were investigated through numerical simulations. High-precision wave gauges and pressure sensors were used to collect data. Numerical simulations were performed using OpenFOAM software, based on the Volume of Fluid (VOF) method, to simulate broken waves. The time-histories of broken wave heights simulated by the numerical model were validated by physical experiment results, and the proportion of errors was less than 5.6%. The results show that the broken wave exerted on different positions of the breakwater shows a different time-history of pressures, and the peak pressure decreases with the decreasing broken wave height (from 0.342 to 0.227 m in the model) and increasing radii of the submerged shell dike (from 0.03 m to 0.18 m in the model). Through dimensional analysis, the relationship between the broken wave pressures and the dimensionless parameters related to broken wave height, breakwater height, and the radii of the submerged shell dike were established. Following the attenuation of the broken wave by the submerged shell dike, the equations for estimating broken wave pressures on various points along the breakwater were proposed. These equations are functions of the broken wave height, the radius of the submerged shell dike, and the height of the breakwater.
Flash Droughts in the Southern United States: A Driver-Impact-Response (DRI) Framework
Authors: Deepa Raveendranpillai , Vijayan Linoj
Published: February 2025

Flash droughts are rapidly evolving drought events, primarily affecting agriculture, with an onset ranging from 5 days to 8 weeks. Previous research has highlighted the significant impact of flash droughts on agriculture and ecosystems, posing unique challenges for drought monitoring and mitigation. Various indicators have been used to identify the regions and occurrences of flash droughts. However, studies indicate that a single unique indicator does not serve the purpose of identifying/monitoring flash droughts in the United States. This study aims to identify flash droughts using indicators, including the Evaporative Stress Index (ESI), Soil Moisture (SM), and Normalized Difference Vegetation Index (NDVI), complemented by data from the United States Drought Monitor (USDM), which is used as a reference. The research examines flash droughts across Florida, Georgia, and Louisiana from 2000 to 2023, incorporating case studies of recent events. The findings indicate that the SM indicator demonstrates the highest consistency (91%) with the USDM, followed by SESI (64%) and NDVI (52%). Seasonally, flash droughts were most frequent in Florida and Georgia during May and October, whereas Louisiana experienced the highest occurrences between June and October. These indicators effectively reflect flash drought impacts, as documented by crop progress and condition reports from the United States Department of Agriculture (USDA). Finally, to enhance understanding and management of flash droughts, the study proposes a Driver-Impact-Response (DRI) conceptual framework is proposed to connect the drivers, impacts, and responses. The DRI framework identifies the drivers initiating flash droughts, evaluates their impacts, and develops mitigation strategies. The DRI framework is specifically of support and management use for planners to summarize the information for decision-making.

Published: February 2025

Underground engineering construction in the karst regions of Southwestern China has become a focal point of China’s advancing regional urban development. However, construction activities interfere with the karst groundwater environment, which is characterized by irregular pore distributions and complex, variable flow patterns. This study establishes a numerical model of the karst water system traversed by Line 2 of the Guiyang Rail Transit in China. Incorporating hydrogeological conditions and tunnel engineering parameters, the model simulates the effects of tunnel construction on the karst groundwater system. The flow-field distribution of the karst groundwater system is altered at various stages of tunnel construction. During tunnel excavation, a drainage zone centered around the subway forms in the groundwater system, altering the groundwater flow field and causing fluctuations in the groundwater level. During the lining phase, the tunnel area gradually transforms into a waterproof zone. Although the groundwater level gradually recovers under rainfall recharge, the waterproofing effect of the tunnel drives the formation of a new groundwater flow field within the groundwater system, changing both the groundwater level and the original flow field. This work offers support for the coordinated development of underground engineering and environmental protection in karst areas, facilitating sustainable urbanization.

Relevancia del consentimiento informado en lesión iatrogénica cubital asociada a remoción de implante anticonceptivo
Authors: Flores-Sandí Grettchen
Published: February 2025

Los procedimientos de remoción de implantes anticonceptivos están diseñados para realizarse de forma segura, por personal capacitado, en el ámbito ambulatorio con anestesia local, pero pueden ocurrir extracciones difíciles que aumentan el riesgo de lesiones neurológicas, musculares o vasculares y un adecuado consentimiento informado del procedimiento es clave para que la paciente comprenda lo ocurrido. Se debe tener presente que los criterios por los cuales una lesión iatrogénica se considera negligente dependen de los estándares aceptados de la práctica médica y de lo que podría esperarse de las acciones de un médico dada la disponibilidad de pautas y evidencia, así como de los estándares aceptados de atención. Descripción del caso: Paciente que manifestó una reacción iatrogénica caracterizada por sangrado uterino anormal asociado a implante de etonogestrel, y en ausencia de un consentimiento informado del procedimiento presentó lesión del nervio cubital durante el intento fallido de remoción del implante profundo, fue derivada ocho meses después a exploración quirúrgica formal para la remoción del implante y evaluación del nervio cubital. Discusión: La lesión del nervio cubital es una complicación seria y poco común del procedimiento de remoción de estos implantes. Es importante documentar su ubicación precisa antes del procedimiento para minimizar el riesgo, así como realizar un consentimiento informado que incluya riesgos poco frecuentes y contribuya a evitar litigios innecesarios. En su prevención adquiere importancia el entrenamiento adecuado de los profesionales que administran y retiran estos dispositivos, así como la derivación temprana a un centro especializado para prevenir daños permanentes

Published: February 2025

تناولت هذه الدراسة تتبع موضوع الوباء في السنة النبوية، مع بيان مفهوم الوباء وما يتعلق به، واستنباط قواعد وتدابير نبوية للتعامل مع الوباء. وتوصلت إلى: أن الوباء مرضٌ عام متفشي، ينشأ عنه كثرة الموت، وهو أعم من الطاعون، فكل طاعون وباء وليس العكس، وقد يطلق الطاعون على الوباء في السنة مجازًا كما جاء في بعض الأحاديث. وأن الوباء آية من آيات الله تعالى كما دلت على ذلك الأحاديث. وأن فيروس كورونا المستجد نوع من أنواع الوباء وليس طاعونا. وأن السنة النبوية حوت قواعد وتدابير وقائية وعلاجية للتعامل مع الأوبئة تصلح لكل زمان ومكان، وفيها توجيه للعبد نحو السلامة والأمان. ومن هذه القواعد والتدابير النبوية: الأمان النفسي في الإيمان الصادق، والحجر الصحي، والنظافة الشخصية، واجتناب مخالطة المرضى، والتداوي وبذل الأسباب، والتضرع بالدعاء، وحسن الإدارة مع حسن الطاعة، والاستقامة في الدين والتحصن بالذكر، والتوبة والعمل الصالح، والدعوة إلى الله تعالى، وأهمية دور العاملين في دفع البلاء، والتثبت في نقل الأخبار، والرضا والطمأنينة وحسن التدبير خصال للمؤمن. الكلمات المفتاحية:أحاديث، الوباء،دراسة، موضوعية، كورونا
أحكام تعليق الصلوات في المساجد لمواجهة جائحة كورونا المستجد (Covid – 19)
Authors: آلاء عادل العبيد
Published: February 2025

يهدف هذا البحث إلى بيان أحكام تعليق الصلوات وغلق المساجد لمواجهة جائحة فيروس كورونا المستجد، يبدأ البحث بعرض تعريف العدوى، والأمراض المعدية، والوباء وفيروس كورونا، وبيان الوباء والعدوى في ضوء الشريعة الإسلامية، وحكم صلاة الجمعة والجماعة وحِكمها، ثم يناقش مدى مشروعية تعليق الصلوات في المساجد بسبب فيروس كورونا، وحجج وأدلة كل فريق، وفق المنهج الاستقرائي في استقراء وتتبع آراء العلماء والمختصين في موضوع البحث، ثم تقييمه وفق المنهج النقدي والمنهج الاستدلالي الاستنباطي وخلص البحث إلى أنه بالنظر إلى الخطاب التشريعي العام؛ يظهر أن إقامة الجمع والجماعات من شعائر الدين التي شرعت لإعلاء كلمة الله، وإعزاز دينه، وهي واجبة على الأمة فلا يجوز تركها ابتداءً، وبالنظر لمورد الخطاب التشريعي الجزئي؛المتعلق بالأوبئة، الخاص ببعض المكلفين، وبعض الأماكن الموبوءة، المؤقتة بزمان متقاصر؛ يظهر رجحان القول بجواز تعليق الصلوات في المساجد حال وباء كورونا، وأن الضرورة تقدر بقدرها، مع ضرورة إبقاء شعيرة صلاة الجمعة والجماعات على الأقل في المساجد الجامعة الكبرى ما أمكن، وأخذ التدابير الشرعية والصحية المناسبة طالما لم يفض ذلك إلى ضرر، وأن الراجح أنه لا تجوز إقامة الجمعة في البيوت؛ لوجود رخصة شرعية لصلاة الظهر حال وجود العذر؛ ولأن ذلك يخالف مقصود الجمعة وكونها من شعائر الإسلام الظاهرة، وأنه لا يصح الائتمام بصلاة الإمام عبر وسائل البث المباشر.
