On Imitation Forms in the Four-Part Divine Service (“Difficult”) by Vasiliy Titov
Authors: Плотникова Н.Ю. 
Published: May 2021

Василий Титов (ок. 1650 – ок. 1715) — выдающийся русский композитор эпохи барокко, в хоровых произведениях которого для различных составов (от трех до двадцати четырех голосов) ярко представлена имитационная техника. Его «Служба Божия» для двух дискантов и двух басов, созданная в 1680–1690-е годы, в одном из рукописных сборников середины XVIII века получила название «трудная», в первую очередь в связи с большим количеством имитационных форм (простые и канонические имитации, бесконечные каноны и канонические секвенции), а также с необычным для партесного стиля типом тематизма, приближающимся к инструментальному. Особый интерес представляют фугированные формы, помещающиеся в экспозиционных разделах частей крупного многочастного цикла Службы, их канонические структуры и своеобразная ладовая организация. В задачи автора статьи входит выявление и характеристика имитационных форм Службы с опорой на теорию С. И. Танеева и методику современного полифонического анализа, определение роли полифонии в построении крупных тексто-музыкальных форм.
Vasiliy Titov (c. 1650 – c. 1715) is an outstanding Russian composer of the Baroque era, who brilliantly used imitation techniques in his choral works for choirs of wide range (from three to twenty-four voices). In one of the manuscript сollections of the mid-18th century, his Divine Service for two treble and two bass voices, composed in the 1680–90s, is referred to as ‘difficult’ — primarily due to the multitude of imitations (both simple and canonic, including perpetual canons and canonic sequences), as well as to the peculiarities of the work’s thematic material, close to the instrumental nature, which is unusual for the partesny style. Of particular interest are the fugue forms that are located in the exposition sections of the parts of a large multi-part cycle of the Service, their canonical structures and a kind of modal organization. The tasks of the author of the article include identifying and characterizing the imitation forms of the Service based on the theory of Sergey I. Taneyev and the methodology of modern polyphonic analysis, and defining the role of polyphony in large-scale vocal forms.

Quem fala trasianka?
Authors: Franco Costa Paterson , Yerro Jorge Hernán 
Published: May 2021

Este artigo parte da tradução e legendagem do filme Viva Belarus! (2012) para português e tem como objetivo principal refletir sobre a tradução da linguagem híbrida belarusso-russa na obra. O longa-metragem se passa em Belarus, ex-república soviética desde 1994 sob o regime do ditador Aliaksandr Lukašenka, responsável por políticas de aproximação com a Rússia e perseguição a dissidentes, sobretudo falantes de belarusso. Nesse contexto, a trasianka, como é conhecida a fala híbrida entre belarusso e russo, oferece desafios para tradução e legendagem com viés identitário. As reflexões sobre as estratégias tradutórias são baseadas na obra de Gonçalves (1990) e identitárias, a partir do pensamento de Fanon (1968) e Foucault (2019), dentre outros.

The Effect of Swabs on Modeling the First Wave of the COVID-19 Pandemic in Italy
Authors: Furlan Claudia , Mortarino Cinzia 
Published: May 2021

The daily fluctuations in the released number of Covid-19 cases played a big role at the beginning of the pandemic, when local authorities in Italy had to decide whether imposing restrictive policies. When an increase/decrease was communicated, especially a large one, it was difficult to understand if it was due to a change in the epidemic evolution or if it was a fluctuation due to other reasons, such as an increase in the number of swabs or a delay in the swab processing. The aim of this paper is both to model the main trend of the outbreak evolution in the number of confirmed cases and to describe the daily fluctuations strongly dependent on the daily number of swabs. For our analysis, we propose a nonlinear asymmetric diffusion model, which includes information on the daily number of swabs, to describe daily fluctuations in the number of confirmed cases in addition to the main trend of the outbreak evolution. The proposed model is found to be the more efficient for prediction, as compared to 6 already existing models, including the SIRD and the logistic models. The new model combines the properties of innovation diffusion models with a parsimonious way to exploit information about swabs. Doi: 10.28991/esj-2021-SPER-04 Full Text: PDF
The Bayesian Confidence Interval for Coefficient of Variation of Zero-inflated Poisson Distribution with Application to Daily COVID-19 Deaths in Thailand
Authors: Junnumtuam Sunisa , Niwitpong Sa-Aat , Niwitpong Suparat 
Published: May 2021

Coronavirus disease 2019 (COVID-19) has spread rapidly throughout the world and has caused millions of deaths. However, the number of daily COVID-19 deaths in Thailand has been low with most daily records showing zero deaths, thereby making them fit a Zero-Inflated Poisson (ZIP) distribution. Herein, confidence intervals for the Coefficient Of Variation (CV) of a ZIP distribution are derived using four methods: the standard bootstrap (SB), percentile bootstrap (PB), Markov Chain Monte Carlo (MCMC), and the Bayesian-based highest posterior density (HPD), for which using the variance of the CV is unnecessary. We applied the methods to both simulated data and data on the number of daily COVID-19 deaths in Thailand. Both sets of results show that the SB, MCMC, and HPD methods performed better than PB for most cases in terms of coverage probability and average length. Overall, the HPD method is recommended for constructing the confidence interval for the CV of a ZIP distribution. Doi: 10.28991/esj-2021-SPER-05 Full Text: PDF

Published: May 2021

Pengukuran serapan CO2 pada tumbuhan sangat penting, untuk mengetahui tumbuhan-tumbuhan yang memiliki kemampuan menyerap CO2 dalam jumlah besar. Kemampuan serapan CO2 suatu tumbuhan dapat diukur dengan memanfaatkan suatu jenis sensor yang dapat mendeteksi atau mengukur konsenstrasi CO2. Pada penelitian ini dirancang dan dibuat suatu perangkat sistem pendeteksi serapan CO2 pada tumbuhan. Perangkat ini terdiri dari sensor MH-Z19, modul Arduino Uno, modul data logger dan chamber daun. Untuk pengujian sistem pengukuran serapan CO2 digunakan beberapa sampel uji yaitu udara bebas, oksigen dengan kadar 95% dan CO2 buatan. Pengambilan data serapan CO2 dilakukan selama satu jam pada pukul 08.00, 10.00, 12.00, 14.00 dan 16.00 WITA dengan pengulangan sebanyak lima hari. Hasil pengukuran menunjukkan pola yang sama. Hal ini ditunjukkan dengan terlihatnya nilai konsentrasi CO2 mengalami penurunan selama satu jam pengukuran. Walaupun tren data menunjukkan kecenderungan yang sama, namun penyerapan yang paling baik terjadi pada hari pertama, ketiga, keempat dan kelima. Untuk hari pertama, ketiga dan kelima kondisi cuaca sangat cerah sehingga penyerapan CO2 yang terukur mencapai 500 ppm - 650 ppm, sedangkan pada hari keempat kondisi cuaca sedikit berawan sehingga penyerapan CO2 hanya mencapai 700 ppm. Sistem yang telah dibuat memiliki presisi pengukuran rata-rata dalam rentang waktu lima hari diatas 80%. Presisi dari sistem pendeteksi dalam rentang 88,67%-94,14%.

Keeping an interaction distance between 1 to 2 m is one of the health protocols during the COVID-19 pandemic. This attempt was made to reduce the spread of the Coronavirus. On the other hand, this health protocol activity is often overlooked, whether intentionally or not. According to the mechanism of the Coronavirus spreading in the form of droplets that comes out during communication, sneezing, or coughing, maintaining distance can be the best effort to minimize the transmission of this virus. Therefore, the availability of a simple, accurate and user-friendly physical distancing alarm system could be a solution in the implementation of this health protocol. In this study, a prototype of a physical distancing alarm based on a distance sensor and a microcontroller in the form of an identity card was developed. Several steps are conducted in developing of this system, namely designing the instrumentation system and testing the performance of the system. System performance is tested through variations in the distance and angle of the objects. The measurement results show that the system can detect objects in front of the sensor up to a distance of 2.8m and an angle of for a distance of 1m. The measurement using different angles of objects was performed for objects on the left and right sides of the sensor. In addition, a warning alarm will be on when the distance of the object exceeds the allowed distance.

Authors: Olusola-Bello MA , Olatunji AA , Ajayi OI , Adekoya AO 
Published: May 2021

Background: Gallbladder (GB) cancer is a rare malignancy with a variable incidence worldwide. Imaging detection at an early stage is elusive. Preoperative imaging for tumour recognition and non-invasive staging is essential to triage patients to appropriate care.
Objectives: To describe the CT imaging findings of GB cancer among Nigerians.
Methods: A retrospective review of the CT images of 15 patients who had gall bladder carcinoma between January 2015 and June 2017 at a private diagnostic facility in Lagos was done.
Results: The age of the patients ranged from 39 to 73 years with a mean age of 60.9 years. The male to female ratio was 1:4.3. Clinical presentations included abdominal pain (61.5%) and jaundice (38.5%). Irregular GB wall thickening (61.5%) and focal mass lesions in the GB (38.5%) were the main features on imaging while 38.5% had associated gall stones. Infiltration of the adjacent liver was found in 76.9% and 60 % of those who had local infiltration of the liver also had intrahepatic metastasis.
Conclusion: A majority of gall bladder cancer cases are still diagnosed in their late stages. CT scan readily delineates regional spread into adjacent organs which may be obscured in other imaging modalities due to adjacent bowel gas.

Published: May 2021

Background: Studies have shown that serum levels of Anti-Mullerian Hormones (AMH) decrease with age as it is also an early and sensitive marker of ovarian reserve in women in the North American, European and Asian regions. Various research works have also generated data about AMH in the Caucasian, Americans and Asians There was a need to compare these known data with African data.
Objectives: To assess the serum levels of AMH in healthy women of reproductive age and determine the relationship between AMH, age, Body Mass Index, parity and menstrual cycle in healthy regularly menstruating women.
Methods: A cross-sectional study of 200 apparently healthy women aged 21-45 years was carried out between January and May 2014. Serum AMH and FSH levels were measured in the participants using Enzyme-Linked Immunosorbent Assay.
Results: The median AMH value was 4.07ng/mL, while the median FSH value was 9.65mIU/mL. The reference 90% CI of AMH was 0.60 -9.71 ng/ml. There was a significant negative correlation between serum level of AMH and age (r = - 0.718, p<0.001).
Conclusion: The serum AMH levels gradually declined throughout the reproductive lifespan of a woman.

Published: May 2021

Background: The assessment of time-trend morbidity and mortality in acute stroke is critical to clinical policy decisions and resource allocation.
Objectives: To determine the prevalence of dysphagia in acute stroke and the impact of dysphagia on short term stroke outcome (30 days post-stroke).
Methods: This was a prospective longitudinal study. Bedside screening for dysphagia modified Rankin score (MRS) and Barthel Index (BI) were performed on acute stroke patients on day 1, day 7, day 14 and day 30 after stroke to determine the frequency of dysphagia. Patients with dysphagia were then compared with age- and gender-matched controls (stroke patients without dysphagia) in terms of stroke characteristics and 30-day outcome.
Results: Of the recruited 200 patients, 99 (49.5%) had dysphagia. Patients with intracerebral haemorrhagic stroke had a significantly higher prevalence of dysphagia (64% vs 36%; p<0.001). At baseline, dysphagic patients had more severe (Mean NHISS score, 22.81 Vs 8.92; p=0.01) and subcortical strokes (57.1% vs 42.9%, p = 0.015). At 30 days after stroke, the mean MRS was significantly higher in the dysphagic stroke patients (3.8±1.02) compared to those without dysphagia (2.5±1.3), (p = 0.001)]. Case fatality was higher among the dysphagic (79.8% vs 15.84%; p = 0.001) and the mean survival time was lower (12.21 days) among the dysphagic group (p = 0.001)
Conclusion: Severe stroke, subcortical stroke and haemorrhagic stroke types were significantly associated with dysphagia at baseline. Dysphagia adversely influenced 30-days morbidity and case fatality in this cohort of acute stroke patients.

Authors: Sogebi OA , Oyewole EA 
Published: May 2021

Background: Recurrence of vertigo indicates a morbidity to the patient and a dilemma for the managing physician.
Objectives: To describe the characteristics of vertigo, document prevalence and explore the characteristics which could independently predict recurrence of vertigo.
Methods: A cross-sectional study of patients managed for vertigo in a tertiary facility was retrospectively done. Patients’ demographic and clinical characteristics, associations of vertigo, audiological symptoms, comorbid illnesses, and duration to achieve control of vertigo were recorded. Recurrence of vertigo was used to categorize the patients. The factors that were associated with recurrence on univariate analyses were evaluated as independent predictors of recurrence of vertigo.
Results: The 73 patients with a male-to-female ratio of 1:1.4 were aged 35 -78 (mean 56.6±9.9) years. The associated symptoms included body weakness (34.2%), audiological symptoms (38.4%), 27.4% had antecedent head and neck injury and vertigo was precipitated or aggravated by changes in the head and neck position in 63.0% Vertigo was controlled within 1 -7 (Median 2) days, 35.6% had a recurrence of vertigo. Age, the experience of nausea and vomiting, previous head and neck injury, presence of comorbidity, and long duration to achieve control of vertigo were significantly associated with recurrence of vertigo. All these factors except the presence of comorbidity could independently predict the recurrence of vertigo.
Conclusion: Vertigo is common in adult females, and mostly positional in type. About a third of patients may have a recurrence of vertigo. Age, especially above 57 years, nausea and vomiting, head and neck injury and prolonged period to control vertigo may independently predict recurrence of vertigo.

Published: May 2021

Speaking using foreign language in front of other people can be one of the most anxiety-provoking situations. Learners who does not enjoy interacting with other people or being the center of attention may exhibit extreme anxiety when they are asked to take parts in oral presentation, discussion, or any other kind of language activities. A study found that online discussion may decrease the effect. It provides a non-threatening situation for learners who are shy and withdrawn. This survey study aims to see whether it is also applied in Indonesian tertiary education by investigating and comparing the learners' level of anxiety in face to face speaking class before Covid-19 pandemic and online speaking class during the pandemic. 120 students who experienced both speaking courses before and during the pandemic participated in the survey. Consistent with the result of other studies, this study found that in average, learners feel less anxious during during online speaking class (48,41%) compare to face-to-face class (60,96%).
