Four drying methods, viz hot air drying (HD), vacuum drying (VD), microwave-vacuum drying (MVD), and vacuum freeze-drying (FD), were used to dry white Hypsizygus marmoreus (WHM). The volatile and taste components of the dried WHM were comparatively analysed by electronic nose technology (E-nose) and head-space solid-phase microextraction combined with gas chromatography-mass spectrometry (HS-SPME-GS-MS). Principal component analysis (PCA) showed that E-nose could distinguish fresh WHM and four dried products clearly. Dominant volatile components in fresh WHM were found to be 1-octen-3-ol, 3-octanone, and (E)-2-nonenal. However, it was found that the drying methods caused damage to the 8-carbon compounds (C8), especially to 8-carbon alcohol greatly. For instance, HD produced more ester materials, MVD yielded more aldehyde compounds, FD brought more hydrocarbon products, and VD produced more ketone substances.

This paper focuses on a small Greek village named Vrisa and a specific condition of Lesbos as the arrival island for hundreds of thousands of refugees, aiming to reconsider places in state of emergency and think of flexible future reconstruction strategies which are able to adapt to the new unpredictable conditions of post-disaster. After the 2017 earthquake, the buildings in Vrisa were marked with red, yellow and green which shows different levels of damage. Also, there are some regulations to restrict the façade, square meter, decoration and funding of rebuilding. By analyzing the characteristics of Vrisa village before earthquake and situation after earthquake, we came up with three reconstruction strategies from different aspects to find solutions. Meanwhile, this paper hopes to provide a reference and suggestions for similar cases of post-earthquake reconstruction.
