Factors associated with Hospitalization among COVID-19 Home Quarantine Patients in Melaka Tengah District, Melaka, Malaysia

Background: COVID-19 is an emerging new disease, recognized in late 2019, has since caused public health pandemic worldwide. Since the establishment of the COVID-19 Assessment Centre (CAC), cases were staged in terms of the severity. The mild cases were allowed for home quarantine and the severe cases were hospitalized. This study will assist healthcare providers to identify the high-risk patients and anticipate proactively, reducing morbidity and mortality. The study aimed to determine the incidence rate of hospitalization among home quarantined patients and its associated factors. Methods: A case-control study design was conducted from 16th August until 30th September 2021 involving newly diagnosed COVID-19 patients under the CAC Melaka Tengah monitoring. A case was defined as home quarantined patient whom later required hospitalization, while a control was defined as home quarantined patient throughout the period. Analysis using Chi-square and Multiple Logistic Regression were done to determine the significant associated factors. Results: There were 13,748 COVID-19 patients; with 8,237 were home quarantined and 82 required hospitalization later (1.0%). A total of 164 patients were included (82 cases and 82 controls). Among the hospitalized, 30.5% were aged 60 and above, 39.0% with comorbidity, 70.7% were symptomatic, and 40.2% were fully vaccinated. From the analysis, the only significant factor associated with hospitalization was age > 60 years old (p<0.05). Conclusion: There were home quarantined patients that required hospitalization later, especially the elderly patients. Thus, the CAC team should give priority for hospital admission to these cases instead of home quarantine order.

The Image of the Other in the (post-)Covid Period: Analysis of Russian-language Internet Queries

The digital age has greatly changed the way information is stored and accessed. The Internet allows us to retrieve an unlimited amount of data from anywhere, at any time of the day or night. The search for new information consistently takes place via search engines, which process and store user query statistics. The analysis of these queries allows us to trace various social trends. At the same time, the personality of the researcher does not affect the "query" of the user, who is fully "sincere and independent" in finding the information he or she needs. Our hypothesis for this study is that by analysing the queries of Internet users we can identify the attitude of the contemporary Russian society to the Other and determine the criteria by which the image of the Other is formed. Considering the nature of the COVID-19 pandemic, the researchers assumed that periods of lockdown may have had a particular effect, increasing interest in certain markers of otherness and decreasing interest in other markers. As a result, we identified 10 models of otherness during the (post)lockdown period, in which food and sexual marker groups are the dominant ones. In particular, the Other-Chinese model, as in previous years, remains worrying. The focus has shifted from the appearance to the sexual and food aspects. The COVID-19 pandemic has played a part in this. The Other-Japanese/Korean model also remains ambiguous, but there is a downward trend in alertness. As for the other models, for the most part they are allert-neutral.

The FUor Star V2493 Cyg (HBC 722)—Eleven Years at Maximum Brightness

At the time of stellar evolution, young stellar objects go through processes of increased activity and instability. Star formation takes place in several stages during which the star accumulates enough mass to initiate thermonuclear reactions in the nucleus. A significant percentage of the mass of Sun-like stars accumulates during periods of increased accretion known as FUor outbursts. Since we know only about two dozen stars of this type, the study of each new object is very important for our knowledge. In this paper, we present data from photometric monitoring on a FUor object V2493 Cyg discovered in 2010. Our data were obtained in the optical region with BVRI Johnson–Cousins set of filters during the period from November 2016 to February 2021. The results of our observations show that during this period no significant changes in the brightness of the star were registered. We only detect variations with a small amplitude around the maximum brightness value. Thus, since 2013 V2493 Cyg remains at its maximum brightness, without a decrease in brightness. Such photometric behavior is not typical of other stars from FUor type. Usually, the light curves of FUors are asymmetrical, with a very rapid rise and gradual decline of the brightness. V2493 Cyg remains unique in this respect with a very rapid rise in brightness and prolonged retention in maximum light. Our period analysis made for the interval February 2013–February 2021 reveals a well-defined period of 914 ± 10 days. Such periodicity can be explained by dust structures remaining from star formation in orbit around the star.

Stability of Nonradial Pulsations in the Be Star [MA93]1506

Period analysis of the 1993–2020 MACHO and OGLE photometry for Be star [MA93]1506 reveals non-radial pulsations are present in all observing seasons, with a mean period of 1.09942 ± 0.00018 days.

INFLUENCE OF RECREATIONAL LOAD ON ORNITOFAUNA OF THE CITY OF VORONEZH

In this work, we determined the number and systematic affiliation of the most common bird species of the Voronezh upland oak forest in the territories exposed to anthropogenic impact. Field studies were carried out from 2019 to 2020 on the territory of the Voronezh upland oak forest. At the sites selected for the survey, a route counting of birds by voices was carried out. The species composition of the avifauna was supplemented by an analysis of information about the habitat of birds and their nesting sites in areas with constant recreational impact. At the selected sites, birds were counted by voices (mating song). From the results of counts in the studied areas, one can see the diversity of the species composition of the avifauna during the reproductive period. Analysis of the data obtained makes it possible to determine the ecological belonging of the species and compare the quantitative indicators of the birds encountered.
