RESUMEN
OBJECTIVE: The present study aimed to explore the biophilic design attributes within a hospice care center from the healthcare professionals' perspective by utilizing a qualitative research and investigated the effect of hospice professionals' attitudes toward the uncovered green features on the prediction of their workplace attachment through a quantitative research. BACKGROUND: In hospice establishments, studies showed that applying biophilic design principles significantly reduces stress and improves emotional well-being. Yet, despite its importance, attitude toward biophilic design, and its significant influence on well-being, satisfaction and attachment to the workplace of hospice healthcare professionals have not yet been researched. METHODS: The qualitative research used semi-structured in-depth interviews among hospice professionals to reveal biophilic design features that exert an influence on their activity, while the quantitative research employed a confirmatory factor analysis and the structural equation modeling to analyze the data. RESULTS AND CONCLUSIONS: The qualitative research generated five biophilic design features, such as open spaces with natural light, natural decorative elements, landscape provided by nature through windows, wooden furniture, and colors that create a warm atmosphere within the hospice care center. The quantitative approach indicated that attitude toward the uncovered biophilic design features in the context of the COVID-19 pandemic significantly improved the healthcare providers' emotional well-being. This dimension, in turn, contributed to their satisfaction with green features/natural decor and attachment to the workplace. Results of this study provide practitioners and researchers valuable strategies to incorporate biophilic design features in the working environments of hospice settings.

In the present study, the composition of essential oil isolated from the roots of Vetiveria zizanioides (L.) Nash, harvested in China, was studied, along with the bioactivities. A green novel method using an eco-friendly solvent, CO2-pressurized ethanol, or carbon dioxide expanded ethanol (CXE) was employed to isolate the essential oil from the root of Vetiveria zizanioides (L.) Nash with the purpose of replacing the traditional method and supercritical fluid extraction (SFE). After investigating the major operating factors of CXE, the optimal conditions were obtained as follows: 8.4 MPa, 50 °C, 5 mL/min ethanol, and 0.22 mole fraction of CO2, presenting an extraction oil that ranged from 5.12% to 7.42%, higher than that of hydrodistillation (HD) or indirect vapor distillation (IVD). The Gas Chromatography-Mass Spectrometry (GC-MS) analysis showed that three major components, including valerenol (18.48%), valerenal (10.21%), and ß-Cadinene (6.23%), are found in CXE oil, while a total of 23 components were identified, 48 components less than using conventional hydrodistillation. Furthermore, the antimicrobial activities of root oils were evaluated by the microdilution method, which showed that CXE oil exhibited an ability against Gram-positive bacteria, especially Staphylococcus aureus, approximately equivalent to traditional samples. Additionally, the DPPH free radical scavenging assay demonstrated that the antioxidant abilities of root oils were sorted in the descending order: IVD > HD > CXE > SFE. In conclusion, after a comprehensive comparison with the conventional methods, the CXE-related technique might be a promising green manufacturing pattern for the production of quality vetiver oil, due to the modification of ethanol by the variable addition of non-polar compressible CO2, ultimately resulting in a prominent dissolving capability for the extraction of vetiver solutes.
