The Internet and social media are crucial platforms for health information. Factors such as the efficiency of online health information, the outcomes of seeking online health information and the awareness of reliable sources have become increasingly important for the elderly during the COVID-19 pandemic. This study aimed to examine differences between elderly individuals’ income above and below the average monthly wage in relation to their online health information efficiency and the outcomes of seeking online health information; to evaluate types of online information sources with online health information efficiency and the outcomes of seeking online health information; and to explore online health information efficiency as a mediator between health status and awareness of online sources. A cross-sectional study design was conducted with 336 elderly participants age 65 or older. The participants volunteered to complete a questionnaire. No differences were found between the two groups regarding efficiency in retrieving health information from official online health sites and Google. Perceived efficiency mediated health status and awareness of online sources. In these challenging times, it is important to provide a tailor-made education strategy plan for reliable sources of online health information for the elderly, in order to enhance their technology safety skills. It is also important to explore other mediating variables between health status and awareness of online sources.

This study presents an investigation into the extent to which emerging building information modelling (BIM) can be applied to construction logistics management (CLM). Given the specialist nature of the domains, the study employed an in-depth qualitative interview, whereby six experts were interrogated about their experiences of BIM for CLM. The study found the main applications of BIM on CLM to be the creation of three-dimensional (3D) site layout plans and four-dimensional (4D) coordination of site processes and common user plant, updating the 4D logistics plan as the project progressed and collaboration in BIM-based logistics coordination. Furthermore, there was a consensus amongst interviewees on improvement in site safety, comprehension of logistics information, efficiency on site, and effectiveness of layout planning as the main benefits. Lastly, the lack of training with implications on understanding was one of the main barriers to applying BIM to CLM. The findings from this study have the potential to stimulate the uptake of BIM by construction logistics practitioners. By so doing, the performance construction project delivery can be improved, and waste can be minimised or eliminated.
