Objective:The purpose of this study is to analyse Critical Risk Features via Digital Buying and to quantify the Risk Factor Score (RFS) during COVID 19 Pandemic. Methods: Theory of Planned Behaviour (TPB), Perceived Risk Theory (PRT) and Theory of Acceptance Model (TAM) were considered as a base models for selection the of variables. The survey instrument used in the present study was designed and validated using Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA). Three hundred and twenty-two sample responses from Mysore city, Karnataka, India, were obtained through e-mail survey from digital buyers during May 2021-July 2021. The EFA, CFA and Linear regression models were adopted for quantitative assessment of risk features associated with digital buying. Findings: The critical risk features associated with digital buying were identified as; Contractual Risk (CR), Financial Risk (FR), Psychological Risk (PR), Perceived Quality Risk (PQR) and Social Risk (SR). The Risk Factor Score (RFS) for male and female digital buyers were noted as 3.7056 and 3.663 respectively. Thus, risk taking via digital buying by male is higher comparatively. The RFS for the group 31-45 years is 3.697, lesser than age group 15-30 (3.699), while the age group 46-60 RFS is noted as 3.827 which is higher comparatively. Novelty: The attempts were made to identify the risks features associated with digital buying during the pandemic. The present study outcome helps digital shopkeepers to respond positively to the needs of digital buyers during pandemic.

This study aims to address quality issues in the production of prefabricated steel structural components for buildings by investigating challenges in quality risk assessment. It identifies key factors contributing to quality problems and establishes an evaluation index system. Traditional methods encounter limitations in handling uncertainty and conducting quantitative analysis. Therefore, the fuzzy Bayesian network (FBN) theory is utilized to perform probabilistic analysis on quality risks during the production phase. This research achieves a more accurate and dynamic risk assessment by integrating the strengths of fuzzy logic and Bayesian networks (BNs) and by utilizing expert knowledge, the similarity aggregation method (SAM), and the noisy-OR gate model. The study reveals that factors such as the "low professional level of designers," "poor production refinement," and "poor storage conditions for finished products" have a significant impact on quality risks. This research offers a novel risk assessment tool for steel structural component production, effectively assisting enterprises in identifying potential risks, formulating risk reduction strategies, and enhancing production quality.

“…Traditional warehouse construction methods often lead to prolonged project durations and increased costs, highlighting the need for more efficient approaches [4,5]. Amidst these considerations, ensuring the health and safety of construction workers remains paramount, especially in environments where regulatory enforcement may vary [6,7]. Prefabricated construction presents an opportunity to mitigate these risks by reducing on-site activities and creating safer working conditions [8].…”

Prefabricated construction, an innovative approach to building, holds immense potential for revolutionizing the construction landscape, yet its implications for worker health and safety in the Sindh region of Pakistan remain inadequately explored. This study addresses this gap by conducting a comprehensive investigation into the health and safety benefits associated with prefabricated warehouse construction in comparison to traditional building methods. Through an extensive literature review, a multitude of advantages linked to prefabricated construction emerged, ranging from environmental benefits like reduced greenhouse gas emissions and improved resilience against natural elements to ergonomic advantages that alleviate physical strain and lower the risk of musculoskeletal injuries among workers. Furthermore, empirical data gathered from 30 construction professionals in Sindh underscored additional benefits, including noise reduction, decreased reliance on formwork, and diminished need for bending during construction activities. Employing the Relative Importance Index (RII) technique, the study ranked these benefits. The mitigation of health and safety threats linked to confined spaces topped the list as the most significant advantage with an RII score of 0.793. Additionally, "Safeguard against natural hazards such as wind and rain" and "Mitigate construction-related falls, trips, and slips" ranked second and third, respectively, with considerable RII scores. However, variations in prioritization across studies highlight the nuanced nature of safety considerations in prefabricated construction, emphasizing the necessity for tailored safety management approaches. Overall, this research sheds light on the substantial health and safety advantages offered by prefabricated construction, thereby informing future practices and policies in the construction industry.
