BIM exhibits strong potential to become a core technological advancement adopted in construction projects. However, the process of BIM implementation is being affected by various factors depending on specific circumstances. This study aims to identify global factors influencing BIM adoption in construction projects. By a comprehensive review of the previous literature, this study managed 39 critical factors impacting construction labor productivity, which were categorized as primary 5 groups, namely, human, management, technology, project, and external. A total of 159 valid samples were collected by respondents who completed a questionnaire survey according to their previous direct or indirect participation in the implementation of construction projects. These factors were ranked based on their Relative Important Index (RII) and descriptive statistics. The findings indicated that the most significant factors affecting BIM adoption in construction project implementation consist of (1) "perceived usefulness," (2) "speed of BIM tools," (3) "perceived benefits of BIM for organization," (4) "technology quality," and (5) "experience and skills".

Introduction: Building Information Modeling (BIM) is characterized by potential benefits at many phases of the construction project life cycle. However, no comprehensive study has been conducted to evaluate the benefits of BIM adoption and implementation for project stakeholders in the Vietnamese construction industry context. Methods: This study aimed to identify and evaluate the benefits of BIM adoption and implementation in construction projects based on the perception of project stakeholders through data collection from 159 valid construction practitioners. The reliability and validity tests were performed to analyze collected data by SPSS 22 software. Results: The results demonstrated that four primary clusters of the project stakeholders received benefits when BIM was adopted in construction projects: architectural and structural design units (10 benefits), facility management units (8 benefits), contractors (6 benefits), and owners (6 benefits). These clusters accounted for 58.954%, 5.975%, 4.682%, and 3.736%, respectively, of the variance that characterized the benefits of BIM adoption. The findings indicated that ‘improve the quality of design drawings’, and ‘minimize conflicts/changes’ were the most significant BIM benefits for architectural and structural design units, whereas ‘convenient for managing project data’ and ‘easy planning and resource mobilization’ were the top benefits for facility management units. For contractors, ‘minimize construction errors’ and ‘construction cost saving’ were the most prominent benefits. Besides, BIM brought owners such striking benefits as ‘maximize project performance’ and ‘easier to choose investment options’.

Perilla frutescens L. is an edible plant used as a food item as well as a folk medicine for human diseases in some Asian countries. Due to limited studies in the extraction of total phenols responsible for its high bio-functional properties, this study is aimed to compare the yields, total phenolic content (TPC), and antioxidant capacities of the extracts between pressurized liquid extraction (PLE) at 100°C with or without ultrasonic treatment and conventional extraction techniques. A batch mode of the PLE system was utilized with the use of water and 50% aqueous ethanol as extraction solvents. Hot water extraction at 80°C and soxhlet extraction were employed as conventional techniques. The extraction yields from each technique were determined before their TPC and antioxidant capacities were examined. The results showed that PLE with and without ultrasonic treatment enhanced the extraction process of TPC as compared with conventional ones. Consequently, PLE resulted in higher antioxidant capacities and lipid peroxidation-inhibiting activity than conventional extraction technique (p < 0.05). However, PLE of bioactive components from Perilla frutescens L. leaves with higher thermal treatment should be considered in future studies.
