Abstract— The teaching process of engineering perspective course (EP) generally faces several challenges awing to the nature of the course, the required skills and the large number of students. Thus, this paper aimed to examine the impact of applying an integrated E-Learning -traditional approach on teaching the Engineering Perspec-tive (EP) course based on an online system; namely Google Class-room Application. The impact of the proposed teaching approach was evaluated on 130 students of the faculty of applied arts, Damietta University during the first semester of the academic year 2019-2020. A questionnaire was designed and administrated online to explore students’ feedback on the implemented approach. Results revealed that the students mainly preferred the proposed approach for its tech-nical feasibility and positive effect on their academic achievement. The study ended up with a suggested framework that was designed for applying integrated approach in a comprehensive manner.

Pine wood (PW) and beech wood (BW) are the most used wood in furniture and other applications owing to their unique characteristics and low machining cost. However, their biodegradability and varied moisture content limit their wider use and durability. Therefore, in this study, nanotechnology was used as a novel eco-friendly approach to enhance the durability, antimicrobial properties, and color of wood. Selenium nanoparticles (Se-NPs) were prepared in spherical shape at varied concentrations (25 and 50 mM) using an eco-friendly method in the range of 35–80 and 40–155 nm, respectively. Se-NPs formation at the nanoscale was confirmed using UV/Vis analysis, transmission electron microscopy (TEM), and X-ray diffraction (XRD). The prepared Se-NPs were then impregnated into PW and BW for different periods ranging from 2 hrs to 1 week. The treated wood were then leached in distilled water for 14 days to eliminate excess Se-NPs from the wood surface. The treated wood surfaces were examined using energy-dispersive X-ray spectroscopy (EDX) and scanning electron microscopy (SEM). Se-NPs impacts on the color properties and antimicrobial activities of the treated wood were evaluated. PW treated with Se-NPs showed better antimicrobial and color characteristics than treated BW. PW samples immersed in 50 mM Se-NPs for 2 hrs showed the highest K/S values, whereas the highest antimicrobial values were obtained for those immersed at the same concentration for 2 days, and 1 week.
