A large number of universities worldwide are paying more and more attention to the application and exploration of online education. As the group with the most significant number of online education users, their participation attitude and participation intention directly determine the teaching performance of online education. This research will incorporate playfulness teaching and scenario variables that reflect the universities’ ability to respond to emergencies. Based on the technology acceptance model, this research proposes an integrated research model of online education participation intention to investigate university students’ online education participation intention to reveal the key factors and mechanisms that affect online education participation intention. A structural equation model of participation intention is constructed, and 342 valid samples are obtained by questionnaire survey. The empirical results of PLS-SEM show that: (1) students’ participation attitude positively affects their participation intention; (2) the perceived ease of use and usefulness positively affect their participation attitude, and the perceived usefulness and ease of use affect their participation intention through the complete mediation of participation attitude; (3) the perceived playfulness does not have a significant impact on participation attitude but has a positive impact on participation intention; (4) the innovative discovery university support positively moderates the relationship between participation attitude and intention during such emergencies. The research found that improving students’ attitudes toward participation, perceived ease of use, usefulness, playfulness, and strengthening university support are all helpful to optimize students’ participation intention in online education. At the same time, it also explored operability suggestions for improving the quality of online education and optimizing future education.
With the rapid development of information technology, e-books have become convenient for students to improve their learning performance, especially when learning complicated concepts. However, research showed that acceptance of e-books by teachers is fragmented, due to several factors including the e-book design. Therefore, this study combined the potential positive impacts of openness and interaction on learning to design an open and interactive e-book for teaching K-12 students AI. It then applied a mixed method to investigate the factors that affect teachers’ acceptance of this open and interactive e-book based on the technology acceptance model (TAM) and interviews. The obtained results showed that teachers’ intention to continue using this e-book is significantly influenced by their perceived usefulness and attitude towards this e-book. Additionally, both the interactive and openness features were very helpful for teachers in using this e-book in their teaching plans. However, some of them raised several concerns like the interactive coding platform should be personalized based on students’ age. The findings of this study could help different stakeholders (e.g., instructional designers, teachers, policymakers) in facilitating the design and adoption of open and interactive e-books.

This work addresses the development and application of Cucumeropsis mannii and Luffa acutangula seed proteins as novel bio-coagulants for fecal sludge concentration to increase the biogas yield. The seed protein content was determined and extracted using 1M NaCl, isolated and precipitated by ammonium sulfate [(NH ) SO ], and dialyzed to obtain the puri ed proteins. Their coagulation/ occulation was compared to Moringa oleiefera and pumpkin seeds as the primary treatment for the fecal sludge concentration. Optimal coagulant dosages of 20 mg/l at pH 7.25 increased the total solids from 0.4-2.8% and obtained 180 to 350 ml/l of fecal sludge volume per liter. The bio-coagulants effect on the supernatant water reduced 71.20% to 96,88% of turbidity, 76.48-88.70% of COD, and 81.33 to 95.30% of ammonia nitrogen. The BMP result has shown that plant seed-based bio-coagulant are effective and triple the methane yield result compared to the FS without bio-coagulant treatment with a speci c methane yield of 192.8 NmL CH 4 /gVS, and FS with bio-coagulant pretreatment was increased up 350.5 to 465.3 NmL CH 4 /gVS, with a ratio 2:1 on VS basis.
