Design and Implementation of e-learning Platform Using Data Analysis

Digitalization is growing like never and e-learning is a major part of it. Over the last decade, a significant growth has been seen in e-learning. The advancements and innovations in technology have created the option of distance learning for people which incorporates different mediums of learning, e.g., video tutorials, slideshows, etc. Moreover, ever since the COVID-19 pandemic has started, the concept of online classes has become an integral part of many people. This coronavirus has compelled to cease the normal functioning of schools, colleges, and universities, and thus, the use of online learning has enhanced. The objective of this work is to develop a robust virtual platform for the students which would work as an alternative for the offline college classes. Many analysis techniques have been incorporated for teachers to evaluate the students’ performance and also to classify them according to the special skills and abilities they possess. We have used J2EE technologies and Bootstrap framework while developing the system. MySQL is used for the database requirement. This system would help the students and teachers to manage their daily study pattern. Most importantly, it gives the benefit of studying at your own pace, anytime, and anywhere. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Pulmonary thromboembolism in COVID-19: Initial experience from India

Pulmonary thromboembolic complications are increasingly being recognised in Coronavirus Disease 2019 (COVID-19) infections. Most of the cases of Pulmonary Embolism (PE) are often missed in presence of non-specific symptoms. This report is about a 90-year-old COVID-19 positive male, asymptomatic on presentation, with no prior co-morbidities who developed acute onset shortness of breath along with elevated D-dimer levels four days post admission. Subsequently, a Computed Tomography Pulmonary Angiogram (CTPA) was done which revealed segmental and sub-segmental thromboembolism in upper and middle lobar branches of right pulmonary artery along with bilateral lower lobe ground-glass opacities consistent with COVID-19 pneumonia. As the patient was haemodynamically stable, he was managed conservatively on low molecular weight heparin and subsequently discharged on oral anti-coagulants. This report highlights the need for prompt evaluation of symptoms such as dyspnoea in COVID-19 patients and to rule out thromboembolic complications in them. In resource limited countries such as India with most of the COVID-19 centres having limited access to CT scans, triaging patients based on clinical suspicion and serially rising D-dimer levels may help identify those with thromboembolic complications.
