Rapid technology advancements resulted a fundamental shift in the education sector which redefined the teaching-learning process and teacher engagement. Based on numerous studies on work engagement models and technology readiness, this study explores, how the teachers’ readiness to embrace educational technologies, impact on teacher engagement. With stratified cluster sampling model, data were collected from principals, managers, students and 122 faulty were participated in this quantitative study using standardized tools. Teachers were highly engaged with students-colleagues and varied across experience/age groups. Technology readiness factors positively impacted on social engagements with students-colleagues. As education technology usage is exponential, more future research is needed.

Digital technology systems are adopted rapidly throughout the globe for the virtual learning process especially with the outbreak of the Covid-19 pandemic. Digital screen-based gadgets are integrated to provide a seamless interactive medium of learning even before the initiation of formal education. Studies on the technology use of younger children are critical as uncontrolled gadget use affects their developmental stages yet these studies are still in the infancy stage. This study analyses the psychoeducational impact of extended use of digital gadgets and mobile dependency on early childhood manifested through their cognition, socialization and behaviour. This descriptive study is based on the random responses of 511 parents about their young children of 3-6 years distributed at five civil districts of Kerala State. From the analysis, it is found that the extended use of digital gadgets influenced young children’s mobile dependency, socialization process, cognition and behaviour patterns. The young children exhibited alienation tendencies and behavioural deviations which are correlated to their screen time. Both male and female reported similar results.  Significant differences were observed with respect to the age of the children and their parental characteristics. Their mobile dependency mediated their extended digital Screen Time to the Behaviour. Significant relation was predicted by extended Screen Time on Behaviour of the students with a partial sequential path through mobile Dependency, Cognition and Socialization. The study shed light on the urgency of parental care and implementation of a balanced gadget usage system to reduce the detrimental impacts of psychoeducational factors.

The sustainable green connected systems are considered as the engine room for fostering the Green- Clean Campuses. The biomass management with organic cycles is crucial factor in tropical sustainable campuses as it tends to produce a huge amount of biomass with multiple organic cycles. This proposed biorefinery model at Chemperi, Kerala which is in tropical region can connect Agri farming, pisciculture, piggery farming, and livestock farming for waste management with a centralized aerobic-anaerobic sewage recycling system. The model has proven benefits of cost optimization, reduced fuel conception, enhancing biodiversity with a sustainable ecosystem, and foster sustainability. The output of these multiple farming provides fresh raw materials for the kitchen with economic and health benefits. This model established at Vimal Jyothi Campus, Chemperi, Kerala found to reduce biomass waste production, biorefinery waste management with energy-saving, inculcating sustainability practices in campus and establishment of Green Clean Campus. The model can be integrated with intelligent monitoring systems and automation.
