ABSTRACT
The rapid generation of large amounts of information about the coronavirus SARS-CoV-2 and the disease COVID-19 makes it increasingly difficult to gain a comprehensive overview of current insights related to the disease. With this work, we aim to support the rapid access to a comprehensive data source on COVID-19 targeted especially at researchers. Our knowledge graph, COVIDPUBGRAPH, an RDF knowledge graph of scientific publications, abides by the Linked Data and FAIR principles. The base dataset for the extraction is CORD-19, a dataset of COVID-19-related publications, which is updated regularly. Consequently, COVIDPUBGRAPH is updated biweekly. Our generation pipeline applies named entity recognition, entity linking and link discovery approaches to the original data. The current version of COVIDPUBGRAPH contains 268,108,670 triples and is linked to 9 other datasets by over 1 million links. In our use case studies, we demonstrate the usefulness of our knowledge graph for different applications. COVIDPUBGRAPH is publicly available under the Creative Commons Attribution 4.0 International license.

Background: Children and adolescents are more vulnerable than other age groups to the psychosocial effects of the COVID-19 pandemic. The modified DT (m-DT) was recently utilized for measuring the prevalence of psychological distress among adult COVID-19 patients. In the current study, we aimed to test the utilization of this m-DT in screening adolescent patients with COVID-19 for psychosocial distress.Methods: Egyptian adolescent subjects with suspected or confirmed cases of COVID-19 at a University Hospital were enrolled. Binary logistic regression tests were carried out to explore the association between the m-DT cut-off scores of 4 and the clinical variables.Results: Forty-eight percent (87/182) of the study subjects experienced significant (m-DT score ≥ 4) COVID-19 related distress. There were significant differences between those with and without significant distress with regards to length of quarantine, presence of underlying medical disorder, and presence of chronic respiratory disorders. Length of quarantine time, presence of chronic respiratory disease, worry, and fever were independent factors associated with significant distress in COVID-19 adolescent patients.Conclusions: Almost half of the enrolled Egyptian adolescents with COVID-19 experienced significant psychological distress. The m-DT was useful, as the current study had identified length of quarantine time, presence of chronic respiratory disease, worry, and fever as independent factors associated with significant distress in COVID-19 adolescents. Further studies are needed.

COVID-19ABSTRACT
BACKGROUND: The COVID-19 pandemic contributed to a significant mental health crisis and caused a widening economic crisis, growing financial loss, and numerous uncertainties. This pandemic brought alarming implications and overall increased risk for psychiatric illness. This study explores the psychological impact experienced by patients who tested positive from coronavirus in the Najran region, Saudi Arabia. DESIGN AND METHODS: This exploratory analysis included 210 COVID-19 positive patients. The study was conducted during a six-month period starting from March to September 2020, in two tertiary government hospitals in Najran, Saudi Arabia. Samples were selected using purposive sampling; survey questionnaire and face-to-face interview to collect the data. Statistical data were calculated using IBM SPSS v. 2.0 to compute the following statistical formulas: percentage distribution, mean, standard deviation, and Chi-square test of independence. RESULTS: The findings of this study revealed that the majority of COVID-19 positive patients were middle-aged adults (n=98 or 46.7%), male (n=178 or 84.8%), and were non-Saudi nationals (n=132 or 62.9%). It was found out that COVID-19 patients experienced bothersome behaviour at a very high level (xÌ =2.63±0.6734). Meanwhile, depression (xÌ =2.51±0.7070), worry (xÌ =2.23±0.8811), and anxiety (xÌ =2.21±0.8719) was only at a high level. CONCLUSIONS: The study revealed that the majority of participants had high levels of depression, anxiety and bothersome behaviours. However, demographic characteristics like age, sex, and nationality were not significantly related to coronavirus patients' psychological health problems. Assessments and interventions for psychosocial concerns, integration of mental health considerations, and treatment for severe psychosocial consequences must be administered in COVID-19 care facilities.
ABSTRACT
School closure was the only main control measure that Japan took into action from late February to late March in 2020. Accurate evaluation of how Japanese citizens responded to the impact of school closure remains a challenge. Data from the Google COVID-19 Community Mobility Report was used to analyze the mobility trend of Japanese citizens regarding six categories, including retail and recreation, grocery and pharmacy, parks, transit stations, workplace, and residential. The median percentage of mobility in all 47 prefectures of Japan was calculated during five periods of time, including one week before school closure, one week, two weeks, three weeks, and four weeks after school closure. There was a significant decline in the mobility trend of transit stations, grocery and pharmacy, parks, retail and recreation, and workplace at the moment after school closure compared to the prior period. Inversely, the mobility trend in staying at home remarkably increased following the implementation of school closure. Our study determined a significant change in the mobility trend of Japanese citizens before and after school closure. These data reflected the responsibility and the consciousness of Japanese citizens in mitigating COVID-19.

COVID-19ABSTRACT
This paper examines the rapid spread of Coronavirus (COVID-19) and its short-term impact on the Shariah-compliant UK Dow Jones market index to capture the dynamic behavior of stock returns at economy and industry levels. Using daily data over the period January 20 to May 20 and ten UK industrial sector groupings, the findings suggest a strong and statistically significant relationship between the COVID-19 pandemic and the performance of the conventional stock market index. The findings also suggest that the disease interacts negatively but insignificantly with the Dow Jones faith-based ethical (Islamic) index compared to its UK counterpart. In addition, through an analysis of sector groupings, the paper shows that the stock returns of the information technology sector performed significantly better than the market, while stock returns of consumer discretionary sector, which includes transportation, beverages, tourism and leisure, consumer services performed significantly worse than the market during the COVID-19 outbreak. Other sector groupings fail to yield significantly plausible parameter values.
