Determinants of Covid-19 Vaccine Acceptance among Students: A Web-Based Global Survey
Authors: Irfan S. Fatima , Ahmed Noel Ayesha , Irfan S. Marriyah 
Published: April 2022

Background: Acceptance of a COVID-19 vaccine is crucial to achieve sufficient immunization coverage to end the pandemic. After initially focusing on adults, the emphasis of vaccination is now being geared towards the younger generation. In order to mandate vaccines in schools and attain widespread vaccine uptake, it is important to understand the key determinants that influence students’ willingness to receive a COVID-19 vaccine. Hence, this study was designed to explore students’ willingness to receive a vaccine, their concerns regarding vaccination, and additional factors influencing COVID-19 vaccine acceptance.
Method: Descriptive analytic cross-sectional study using snowball and convenience sample technique was conducted from July - September 2021. Social media networks such as Twitter, WhatsApp and Instagram were used. Data from the student population of both genders receiving secondary and post-secondary education was collected from the Asia-Pacific, Middle East, Europe, and America (26-countries from all over the world). Descriptive statistics and Chi square tests were used. Multivariate logistic regression analysis was used to determine significant predictors for vaccine acceptance.
Results: A total of 201 participants completed the questionnaire (response rate 53%). We found considerably higher willingness (85%) to take a COVID-19 vaccine in the sample; highest among students in the West (95.0%), followed by Asia-Pacific region (84.0%) and the least among Middle East (80.0%). A statistically significant association (p = 0.000) was found between the female gender and the willingness for vaccine receival. Preserving health [OR 18.82, 95%CI 2.88-122.80], understanding the importance of vaccinations for protection against COVID 19 [OR 34.28, 95%CI 3.72-315.95], concerns about vaccine safety [OR 1.77, 95%CI1.21-28.78] and worry about potential side effects [OR 0.027, 95%CI 0.004-0.213] were significant predictors for vaccine acceptance.
Conclusion: The majority of students were willing to get the COVID-19 vaccine to protect their health; but there were concerns about safety and side effects. Greater understanding about the importance of the vaccine, for protection against COVID-19 was predictive of willingness to receive the vaccine. This study provided evidence for health authorities to provide clear information, reduce misinformation and design measures to address the fears and worries about the effects of the vaccine. Future qualitative studies should be directed towards understanding differences in students’ perspectives in depth.

The aim of the research was a comparison of soil seed bank, formed by the influence of different crop production systems (organic, integrated, conventional and monoculture of winter wheat) with weed infestation in the winter wheat. The study was conducted at the Experimental Station of the Institute of Soil Science and Plant Cultivation – State Research Institute in Osiny (Lublin province), where these crop production systems, characterised by different crop rotations and agricultural practices, have been compared since 1994. The assessment included the analysis of weed species composition and the number of weeds in winter wheat cultivated in different crop production systems as well as the weed seed stock in the 0–20 cm soil layer under winter wheat. The soil seed bank and winter wheat infestation was analysed using ecological indices: Shannon's diversity index (H') and Simpson's dominance index (SI).
The number of weed seed species in the soil was higher than the number of weed species in a winter wheat canopy in all compared systems. The difference between the number of species in a canopy and in the soil was the smallest in the organic system. The monoculture of winter wheat was characterised by the lowest diversity of weed flora and soil seed bank. Shannon and Simpson indices showed the bigger similarity between soil seed bank and weed infestation in the organic system and the lowest in conventional one and monoculture. Small differences of species number in weed seed stock in the compared systems and the narrow ranges of Shannon and Simpson indices suggest smaller dynamics of change of soil seed bank than weed flora.

The aim of the experiment was agrochemical evaluation of the influence of liming and fertilization with ammonium or nitrate nitrogen on the content of available forms and mineral fractions of phosphorus in soil. The content of available phosphorus was determined in distilled water, acid sodium carbonate and according to Egner-Riehm method. The mineral fractions of phosphorus were determined according to Chang and Jackson method with modifications according to Askinazi, Ginzburg and Lebiedewa. The obtained results indicated that the greatest increase of available phosphorus was caused by fertilization with superphosphate at higher levels. The application of liming influenced the increase of available phosphorus in soil. The effect of fertilization with various nitrogen forms and nitrogen levels on the content of available phosphorus was not significant. Liming as well as fertilization with calcium nitrate caused the increase of easily soluble fraction in the soil. The content of aluminum phosphates was higher in treatments with lower pH values. The content of calcium phosphates was the highest in treatments limed and fertilized with calcium nitrate at a higher rate.

Published: April 2022

The possibilities of operational control of the parameters of liquid fuels and lubricants with impurities using the resonator method of microwave dielectrometry are considered. Preliminary studies of liquid fuels and lubricants (gasolines, diesel fuels, kerosene, oils) showed that the values ​​of the real and imaginary components of the complex dielectric constant of the listed fuels and lubricants are in the operating range of the resonator microwave dielectrometer.
The high resolution of the microwave resonator method determines the prospects of using this method for analyzing the complex dielectric constant of mixtures of fuels and lubricants with various impurities, including water, alcohols, benzene, etc.
For a mixture of gasoline with benzene, it was experimentally established that with a small addition of benzene (no more than 15%), an increase in the real component of the complex dielectric constant of the mixture is observed, and with a benzene content exceeding 15%, an increase in both components of the complex dielectric constant of the mixture takes place.
The process has also been installed, but the NHF dielectrometer has made it possible to identify the transformer in real time due to the presence of water in the amount of 14, 28 and 56 grams per ton of oil. The research results indicate that the microwave dielectrometry method can be considered promising for monitoring the quality of transformer oil both during the filling process and for monitoring its quality during the operation of high-voltage transformers.
The results of the initial stage of research on alcohol gasolines have not yet revealed the predominant effect of the alcohol additive on the location of the experimental points on the complex plane. This circumstance is most likely due to the fact that alcohol gasolines with a close octane number can have a significantly different chemical composition.

Teknologi yang semakin maju memudahkan siapa saja menafaatkannya untuk berbagai kegiatan, seperti kegiatan perkuliahan. Terlebih di masa pandemi Covid-19 yang terjadi sejak tahun 2019 hingga sampai penelitian ini dilakukan. Covid-19 atau yang dulunya disebut dengan SARS-CoV2 merupakan sebuah wabah pneumonia yang berasl dari virus. Virus ini mulai terdengar pertama kali di Wuhan, Cina pada Desember 2019 (Ciotti et al., 2020). Kegiatan perkuliahan dilakukan secara daring untuk mencegah penyebaran virus ini. Salah satu teknologi yang banyak digunakan ketika pandemi Covid-19 adalah video conference. Dengan video conference pertemuan dapat dilakukan meski orang yang hadir saling berjauhan. Zoom merupakan satu aplikasi berbasis cloud yang saat ini sering digunakan sebagai communication video (Azkiya, 2021). Zoom adalah satu aplikasi video conference yang ramai saat ini digunakan dalam berbagai kegiatan, termasuk kegiatan perkuliahan. Karena hal tersebut penting untuk mengetahui seberapa besar penerimaan mahasiswa terhadap aplikasi Zoom yang mereka gunakan untuk perkuliahan.

Spatial scale of urban agglomeration externalities on the Rostov region in Russia
Authors: Mikhaylova Anna , Gorochnaya Vasilisa 
Published: April 2022

English Abstract:
The article focuses on the differences in the impact of urban agglomeration externalities on the development dynamics of different spatial zones of the region of Rostov, the tenth largest city of Russia, namely the agglomerative, contiguous, and remote. We also measure the divergence of the agglomeration itself, segregating the agglomerative municipalities into core, interjacent, and peripheral. We hypothesize that spatial proximity to the agglomeration core favors economic growth with a gradual decrease with the distance. The research results suggest that municipalities with an intermediate location – contiguous type, feature the worst indicator performance. These settlements are located not close enough to the agglomeration core to be attractive for pendulum labor migration and the location of enterprises and not far enough to develop an independent infrastructure system for economic development.Spanish Abstract:
El artículo se centra en las diferencias del impacto de las externalidades de aglomeración urbana en la dinámica de desarrollo de las distintas zonas espaciales de la región de Rostov (la décima ciudad más grande de Rusia): la aglomeración, la contigua y la remota. Medimos la divergencia de la aglomeración, segregando los municipios aglomerados en centrales, inter-contiguos y periféricos. Nuestra hipótesis es que la proximidad espacial al núcleo de aglomeración favorece el crecimiento económico disminuyendo gradualmente con la distancia. Los resultados sugieren que los municipios con una ubicación intermedia —tipo contiguo— presentan el peor rendimiento. Estos asentamientos no están situados lo suficientemente cerca del núcleo de aglomeración como para ser atractivos para la migración laboral pendular y establecimiento de empresas, ni se encuentran suficientemente lejos como para desarrollar un sistema de infraestructura independiente para el desarrollo económico.French Abstract:
Cet article analyse les différences d’impact des externalités des agglomérations urbaines sur la dynamique de développement de différentes zones spatiales de la région de Rostov, la dixième ville de Russie en population : les agglomérations, les contiguës et les éloignées. Nous classons les municipalités agglomérées en trois catégories, centrales, intercalaires et périphériques, et émettons l’hypothèse que la proximité spatiale du noyau de l’agglomération favorise la croissance économique, avec une diminution progressive selon la distance. Nos résultats suggèrent que les municipalités ayant une localisation intermédiaire - de type contigu - présentent les pires performances en termes d’indicateurs. Elles ne sont pas assez proches du coeur de l’agglomération pour être attrayantes pour la migration pendulaire de la main-d’oeuvre et la localisation des entreprises, et pas assez loin pour développer un système d’infrastructure indépendant pour le développement économique.

OBJECTIVE
The authors developed a method to predict the etiology of intracranial large-vessel occlusion stroke (ILVOS) before endovascular treatment.

METHODS
The authors retrospectively evaluated two etiologies of ILVOS—intracranial atherosclerotic stenosis–related occlusion (ICAS-O) and embolism-related occlusion (EMB-O)—in a cohort of patients from the National Comprehensive Stroke Center database of China. Patients were randomly divided into the derivation and validation cohorts at a ratio of 2:1. The authors derived the score in the derivation cohort and assessed the score in the validation cohort.

RESULTS
The authors identified 608 of 662 patients with ILVOS who received endovascular treatment during the study period. After adjustment for confounding factors, hypertension (OR 2.90, 95% CI 1.34–6.26), diabetes mellitus (OR 2.80, 95% CI 1.45–5.42), absence of atrial fibrillation (OR 27.29, 95% CI 13.27–56.09), National Institutes of Health Stroke Scale score < 7 (OR 2.92, 95% CI 1.22–6.99), and absence of the computed tomography hyperdense sign (OR 2.86, 95% CI 1.22–6.74) were significantly related to ICAS-O. A score was derived to help predict ICAS-O or EMB-O. The area under the curve values of the receiver operating characteristic curve for ICAS-O identification were 0.886 (95% CI 0.839–0.933) and 0.880 (95% CI 0.846–0.914) in the derivation and validation cohorts, respectively.

CONCLUSIONS
The atrial fibrillation–blood pressure–clinical neurological deficit–computed tomography hyperdense sign–diabetes mellitus (ABC2D) score can be used to identify atherosclerotic or embolic etiology of patients with ILVOS who require emergency endovascular treatment.

Published: April 2022

BACKGROUND
Neurocysticercosis (NCC) is an infectious parasitic disease in which humans are the middle host in the life cycle of Taenia solium. It is currently considered to be a neglected tropical disease. According to their location, cysts can cause epilepsy, hydrocephalus, arachnoiditis, and intracranial hypertension. The subarachnoid is the rarest and most morbid form among all forms of NCC presentation.

OBSERVATIONS
The authors report an odd case of subarachnoid NCC (SUBNCC). It was treated with expanded endoscopic endonasal surgery. Unfortunately, the patient developed a high-output nasal leak and meningitis after cyst removal, which demanded additional surgical procedures. Nonetheless, the patient showed a good clinical outcome after surgical interventions.

LESSONS
Endoscopic endonasal approach of SUBNCC can be safe and curative. Neverthless, the presented report shows that severe complications can arise from the procedure. The authors hypothesized that placing an early cerebrospinal shunt would reduce the patient’s morbidity before difficulties arose.

Published: April 2022

The marked drop in the frequency of Helicobacter pylori infection resulting from the use of antibiotics and potent anti-acid medications has substantially lowered the prevalence of peptic ulcer disease in recent decades. Management of this condition, however, is challenging because of the escalating perils of antibiotic resistance and the abuse of anti-inflammatory drugs. For example, the increased prevalence of cholangiocarcinomas may associate with this peptic ulcer disease management including the prolonged use of proton pump inhibitors. Cholangiocarcinoma is one of the most lethal cancers and accounts for almost 15% of all hepatic malignancies. This review provides a concise summary of the latest findings in the pathogenetic mechanisms of cholangiocarcinoma, essentially focusing on peptic ulcer disease and its associated therapies. We also suggest interventions that may reduce Helicobacter pylori infection and peptic ulcers with the bacteriostatic agent, melatonin. Melatonin treatment may reduce the incidence of this devastating cancer or improve the outcome of individuals that develop this disease.
