Importance-Performance Analysis of Destination Attributes of an Emerging Astrotourism Destination in Kerala, India Sindhu Joseph, Jijo P. Ulahannan, Senthilkumaran Piramanayagam New Space, 2022 Astrotourism is special interest tourism that can complement traditional tourism and leverage community livelihood and empowerment. This article aims to explore the possibility of developing astrotourism in Kerala by conducting a study in areas identified as astrotourism spots where solar eclipse 2019 was first visible in India. The data were collected from the inbound and domestic tourists who witnessed the event. The study found that the study areas have ample potential for developing astrotourism but lack professional integration. The study establishes that any destination with astrotourism resources can be developed as a special tourism niche in an alternative tourism perspective with due importance on carrying capacity levels and scientific aspects as the visits happen due to intrinsic and extrinsic motivations. Furthermore, the study emphasizes India's increased relevance in the global space science map and points out its potential as a future space tourism destination.
CONVERGENCE OF COMORBIDITY AND COVID-19 INFECTION TO FATALITY: AN INVESTIGATION BASED ON HEALTH ASSESSMENT AND VACCINATION AMONG OLDER ADULTS IN KERALA, INDIA Sindhu Joseph, Jijo Pulickiyil Ulahannan, Parvathy A J Asia Pacific Journal of Health Management, 2022 OBJECTIVE: To investigate the impact of age, comorbidity, and vaccination in the fatality of older COVID-19 patients in the state of Kerala, India. METHODS: A cross sectional study, adopting a mixed method approach was used and conducted among the older population in Kerala. To study the health profile of study participants 405 older people were surveyed and 102 people were interviewed in-depth at their households between June to November 2020. The results of the study were triangulated with elderly COVID-19 fatality data available from the citizen-science dashboards of the research team and Department of Health, Kerala. Vaccination data was retrieved from the Co-WIN government website (cowin.gov.in) to study its impact. The data was analyzed using the IBM SPSS version 22.0. RESULTS: Age is a predictor of COVID-19 fatality. Diabetes, hypertension, CAD, CKD and COPD are the significant predictors of elderly COVID-19 fatality in Kerala. The current comorbidity profile of the total older population matches with the comorbidities of the COVID-19 elderly death cases. CFR and IFR have declined even when the CMR is high in the second wave of COVID-19 with more deaths. This is attributable to vaccination even though there exists a lesser chance for breakthrough infection. CONCLUSIONS: Age and comorbidities can predict potential fatality among older COVID-19 patients. Timely and accurate health data and better knowledge of high-risk factors such as comorbidity can easily guide the healthcare system and authorities to efficient prevention and treatment methodologies. Knowledge on prevailing NCDs can drive early preparedness before it converges with an epidemic like the present zoonotic disease. Vaccination is an effective tool in preventing infection compared to the unvaccinated even though the chance for breakthrough infection is there, particularly, in people with comorbidities.
A citizen science initiative for open data and visualization of COVID-19 outbreak in Kerala, India Jijo Pulickiyil Ulahannan, Nikhil Narayanan, Nishad Thalhath, Prem Prabhakaran, Sreekanth Chaliyeduth, Sooraj P Suresh, Musfir Mohammed, E Rajeevan, Sindhu Joseph, Akhil Balakrishnan, Jeevan Uthaman, Manoj Karingamadathil, Sunil Thonikkuzhiyil Thomas, Unnikrishnan Sureshkumar, Shabeesh Balan, Neetha Nanoth Vellichirammal, and Journal of the American Medical Informatics Association, 2020 Objective India reported its first coronavirus disease 2019 (COVID-19) case in the state of Kerala and an outbreak initiated subsequently. The Department of Health Services, Government of Kerala, initially released daily updates through daily textual bulletins for public awareness to control the spread of the disease. However, these unstructured data limit upstream applications, such as visualization, and analysis, thus demanding refinement to generate open and reusable datasets. Materials and Methods Through a citizen science initiative, we leveraged publicly available and crowd-verified data on COVID-19 outbreak in Kerala from the government bulletins and media outlets to generate reusable datasets. This was further visualized as a dashboard through a front-end Web application and a JSON (JavaScript Object Notation) repository, which serves as an application programming interface for the front end. Results From the sourced data, we provided real-time analysis, and daily updates of COVID-19 cases in Kerala, through a user-friendly bilingual dashboard (https://covid19kerala.info/) for nonspecialists. To ensure longevity and reusability, the dataset was deposited in an open-access public repository for future analysis. Finally, we provide outbreak trends and demographic characteristics of the individuals affected with COVID-19 in Kerala during the first 138 days of the outbreak. Discussion We anticipate that our dataset can form the basis for future studies, supplemented with clinical and epidemiological data from the individuals affected with COVID-19 in Kerala. Conclusions We reported a citizen science initiative on the COVID-19 outbreak in Kerala to collect and deposit data in a structured format, which was utilized for visualizing the outbreak trend and describing demographic characteristics of affected individuals.
Effectiveness of concatenated dynamical decoupling for polarization decoherence in optical qubits Sajeev Damodarakurup, Jijo P. Ulahannan, Ram Soorat Optics Infobase Conference Papers, 2016 The effectiveness of concatenated dynamical decoupling scheme to combat polarization decoherence in optical qubits is examined. The scheme is found effective in preserving the purity of optical qubits in a decohering birefringent environment.
