Under the COVID-19 Environment, Will Tourism Decision Making, Environmental Risks, and Epidemic Prevention Attitudes Affect the People's Firm Belief in Participating in Leisure Tourism Activities?

The study was conducted to understand the travel intentions of Dajia Matsu pilgrimage participants through tourism decision making, environmental risk perception, epidemic prevention attitude, and physical and mental health assessment. A questionnaire survey was used to collect 230 questionnaires in the field during the 2021 pilgrimage, and structural analysis was conducted using SPSS 26.0 and AMOS 20.

Verification of enzymes deterioration due to Cu(II) presence in an enhanced biological phosphorus removal system.

This study experimentally demonstrated that polyphosphate accumulating organisms (PAOs) losing the abilities of anaerobically synthesizing polyhydroxyalkanoates and aerobically taking up phosphate under Cu(II) presence was due to the inhibition of enzyme activities of acetyl-CoA synthases (ACS) and polyphosphate kinase (PPK), respectively. ACS activity tests showed the apparent maximum specific activity (Vmax) of ACS decreased with increasing Cu(II) concentration, revealing Cu(II) is a mixed inhibitor for ACS. Inhibition coefficients showed Cu(II) has a higher affinity for free ACS than for ACS-coenzyme A complex.
