Recently coronavirus known as SARS-CoV-2 long COVID-19 or a new variant of Coronavirus 2, the virus has resulted in more than 144 million infections and more than 3 million deaths, badly affects global education, health, and research. So it is obligatory to steady-recovery the whole system. The Doctor / Contractor / Freedom-Fighter / Social-Reformer / Philanthropist Reverent Dinna Nath Das (Karmaker) was established the “Dinna Nath Das Middle School and Dispensary for Free Education and Health for All” by donating Rs. 50,000/- (Fifty thousand rupees) with ‘Company Papers’, and land in a deed during the British periods. According to his modern-foresighted-views, and overcome these pandemic-situation, it is emphasized on the ecofriendly-modern-green-digital-infrastructure-and-facilities attached with air-purifier, the priority- and moral-activity-based-education with online-and-offline-regular-digital-teaching-learning-process, maintaining COVID-19 protocol sitting arrangements, and the active interactive-involvement, and positive attitudes with maintaining equalities among students and communities regarding the digital-class in outside-and-inside, regular fumigation of all the rooms, campus including school-dress, mandatory taking the free-vaccine-nationalism-equity-passport for all students, parents, legal guardians and family member, regular consume easily digested-nutritious-biomedical-meals with fruits-and-ginger-drinks, transforming the ‘Common-Activity-Based-Ecofriendly-Complex-Ecosystem-Model’, and school prevails with the enriched joyful-teaching-learning-process, and environment, biodiversity conservation, agriculture, science-technology-communication, socio-economy-welfare, where the owl act as keynote species, and where the bat confirm the clues to preventing-and-treating-COVID-19 by boosting the natural immunity, and helps to develop the future-policy or model; the ‘Sustainable 21st-Century-Coronavirus-2 Resistance-Futuristic-School is the Mirror of the Society in the New Normal Situation Again’.

According to the imperial Gazette of 1810 and the Bardhaman Raj website, there were two Middle English Schools with dispensaries in Burdwan. The Doctor / Contractor / Freedom-Fighter / Life-Long-Councilor /Social-Reformer / Philanthropist / Reverent Dinna Nath Das (Karmaker) was established this “Dinna Nath Das Middle School and Dispensary beside the Damodar river for Free Education and Health for All” by donating Rs. 50,000/- (Fifty thousand rupees) with ‘Company Papers’, and land in a legal deed on June 25, 1906, during the British periods which is still on the go as the name of Kanchannagar D.N.Das High School (HS), Co-education, affiliated to West Bengal Board of Secondary and Council of Higher Secondary Education, producing 38 state-level scholars up to 1956. But it loses its glamour due to the dark phase as natural thrashes again and again. But we are proud to rescue the same from 2001 onwards, and from 2007 under the guidance of Dr. Subhas Chandra Datta, Headmaster and Secretary, with the constant efforts, the old school building has been totally changed in a new shape both externally and internally with the help of the backward-community. The captured land including play-ground has been resolved, and the school is blooming with gradually increasing student strength; service to the students; over all-round development; various rejuvenating programmers; providing up to date education and mental boost up, forming the school as the “Human-Resource-Development-Centre reflecting Mirror of the Society”. Recently Dr. Ranjan Mukherjee, District Coordinator of Sishu Sathi Scheme at Department of Health and Family Welfare, Government of West Bengal, Bardhaman-713101, West Bengal, India, and Dr. Dipanitwa Malik, M.B.B.S., Burdwan Medical College & Hospital, has come for a health checkup of students especially emphasis on COVID-19,.but students face mainly dental, eye, skin and gynecological problems. Ex-Professor Dr. Sk Abdul Mahmud, M.D.S. (Cal), a specialist in oral and dental diseases, says during treatment of Mr. Bodhisatwa Datta, Physics Honors student and Dr. S.C. Datta, headteacher, that it is a very difficult situation in dental surgery as well as treatment for infection of coronaviruses, and gum disease linked to severe COVID-19 outcomes also [1,2]. The Dinna Nath Das Dispensary had a good reputation for not only treatment of different epidemic diseases like malaria, plague, dengue, and different infectious diseases, and place for refugees declaration in 1965, etc., but also effective in dental surgery (Plate 1). Currently, it enters again into a drastic dark phase as natural pandemic thrashes the previous COVID-19 or recent SARS-CoV-2 or long COVID-19 or a new variant of Coronavirus-2, the virus has resulted in more than 144 million infections and more than 3 million deaths, badly affects global education, health, and research, and it makes the crisis of dropout, socio-economic-health, discrimination, low wages, child labor and labor protections, healthcare and ‘social determinants of health’, education. trafficking, and violence with neurological or psychological effects on students, teachers, parents, guardians, communities, academic mother, and scientist, and different neighboring families, and risk of early marriage or early pregnancy, poverty, and increases of child labor also. Some non-governmental school teachers are in tension regarding their non-received salaries or losing a job also. And in Figure 1 shows the daily press briefing of Purba Bardhaman (Date: 26/04/2021, up to 5.00 P.M.) as well as Burdwan Municipality. So it is obligatory to steady-recovery of the ‘Education and Health’ as well as whole system snatching its glamour [1,2].

According to Dinna Nath Das, we strongly believe in inspiration as it is everywhere and we do also believe in successes as well as in failures and our goal are to transfer every failure into success and possibilities, providing our students with enough space to make mistakes and then we help them to learn from it. And we are glad to air that we are executing every instruction as laid by the Government successfully and we promise to do that in future also. So it is an urgency to recover sustainable the education system and ‘lost learning’ among students after the pandemic, by preparing students for activity-based moral real digital (online and offline mode) education without fear of examinations, and the green-and digital infrastructure and -facilities in the education system or place, procedure, and active involvement and interaction in the teaching-learning, and need to manage the inequalities in the home or communities, as well as inside the classroom. Now in this paper, it is emphasized the steady sustainable reopen the schools and to reorient by developing ideas or policy or initiatives for the preventive-measures against “21st century-various-human-diseases like COVID-19-Pandemic”, due to great loss of lives and transmission or reinfection of coronavirus-2 or long COVID-19 [3-11].

Location of dinna nath Das School and dispensary

The Kanchannagar D.N. Das High School (HS) and Dispensary, is located at 24 no. Ward of Burdwan Municipality beside the Damodar river, Bardhaman, Government of West Bengal, where the temperature was 28 ± 5?, the ratio was 75 ± 5% and soil pH 5.8, and Burdwan is extending from 22^o56' to 23^o53' North latitude and from 86^o48' to 88^o25' East longitudes, with sandy soil, well-drained and slightly acidic in nature and therefore the average rainfall was 150 millimeters.

Green digital infrastructures with teaching-learning activity and process

The Kanchannagar D.N. Das High School (HS) and Dispensary (Plate 2) will be set up a steady potential recovery-planning maintaining health and hygiene protocols of post-pandemic strong-free-Wi-Fi hotspots facilities, ICT (information and communications technology)-based regular potential carton or gameplay or balanced or quiz or puzzle -based effective enjoyable and loveable moral practical green digital teaching and learning shifted-attendance-based online-and offline-classes; by the 2-3 hours digital-or green open-or shifted-class mixing on-line (40-50%) and 3-2 hours activity based off-line face-to-face instruction (60-50%) totaling 5 hours maximum class with proper fumigation of school, all smart digital class room with smart boards, wearing fumigated-school-dress, physical distancing sitting arrangements, maintaining discipline and strictly shifted attendance protocol, preventing overcrowding, and attaching strong air purifier for fresh air room ventilation, potential effective revised green digital shifted-protocol-routine (at least 50% present in school for digital as well as activity based offline green class, and other 50% will be followed class from home), green-ICT-infrastructure, connectivity, broad-band access, free supply-able and available of devices such as laptops or desktops or tablets, mobile phones, ed-tech support and ed-tech training for all teachers, students and even communities also, scope of school midday meal with nutritious weeds-vegetables-fruits-food as biomedicine midday meal with ginger-drinks to all by increasing budget of education and proper use of educational fund, stipends, health check for screening testing to rapidly identify and isolate asymptomatic infected individuals, and mentoring of students, active involvement of local communities, administration and collaboration with NGO (non-government organizations) , and vaccinating all the students, teachers, parents, legal guardians and communities for ‘Vaccine-Nationalism-Equity-Passport, RO (reverse osmosis)-system for pure drinking water for all (including communities), regular school-dress washing and fumigation, germfree dress changing-room for all, big prayer hall cum auditorium, big community hall cum waiting room with digital or e-library, bio-toiles with big washing room, green cycle stand, big general library, museum, green-gymnasium, different craft gallery, innovation hub, discovery laboratory with different basic laboratories, robotic laboratories, different science and cultural clubs, healthcare and retail rooms, eco-park, rainwater-harvesting with fishery and floating-gardening or aquaponics shaded by solar-panel OR covered by wire net with hanging artificial-nests, OR rooftop- or vertical- gardening or hydroponic attached with bird’s- or sky- watching balcony, different types of artificial-nests in the building as well as in the trees with health and hygiene painting, medicinal- and nutritional-garden with organic manure plants, forming the ‘Common-Ecofriendly-Complex-Ecosystem’ with landscaping by trees, garden, biomedical-midday-meals like amaranth, okra, cowpea, cucumber with ginger drinks for all etc., as ‘Social Vaccines or Vaccine or Policy Developer Vaccine, store-grains reservoir’s, indoor, security [12].

room with watch tower, route-chart for easily locating with fire safety and easy entry main gate, school building and all rooms itself maintaining health and hygiene, and different awareness of health and hygiene poster / flex / chart / banner etc., which emphasis on the development of human being — intellectual, physical, emotional, aesthetic, and moral — in an integrated manner in the community also. Teachers always apply up-to-date appropriate innovative and creative methods using MTL (Materials for Teaching Learning) like cartoon or computer-game play etc., to promote the learning process by attracting the student academically and socio-emotional enthusiasm. And maintain all COVID-19 protocol, rules, and regulation safety measures, preventing transmission of the virus among the students, teachers, and local communities [13-18].

Table 1 showed the effects of biomedicine and the ‘Common-Ecofriendly-Digital-Complex-Ecosystem’; the different types of animals with the regular students, teachers, guardian-communities, administrator, and visitors, will create the ‘Joyful-Environment’ with the enriched relationship between schools, parents, and their children, and help to build a brighter future for young people and our society as a whole, and the owls apparently act as a social keystone-species within these food-chain-relationships, consuming rats that spoil food items of mid-day-meals, store-rooms, and documents, and bats that make building dirty by their excreta. And it arouses the attraction of locality on ecology-food-chain-relationships-issues and improves sustainable-fishery, and kitchen-garden-management, micro-and macro- climate issues, and community health, and it plays the role of the simplest carnivore, predating on juveniles and bats. And the present preventive treatment measures revealed that the potential-biomedicine meals are highly effective in controlling diseases by boosting natural immunity against coronavirus with no side-effects in the Kanchannagar D.N.Das school area, which is confirmed from; Figure 1 shows the daily press briefing of Purba Bardhaman (Date: 26/04/2021, up to 5.00 P.M.) as well as Burdwan Municipality with 76.74% recovery rate and 1.15 mortality rate.
