Published: August 2020

Велика кількість проведених останнім часом досліджень свідчать, що особливе місце в складній системі механізмів нейрогуморальної регуляції роботи органів належить мелатоніну, унікальні механізми дії якого відкривають додаткові можливості нормалізації артеріального тиску. Метою проведеної нами роботи був аналіз порушень мелатонінутворювальної функції епіфізу та показників офісного артеріального тиску у хворих на хронічну хворобу нирок 5 стадії, що лікуються гемодіалізом та визначити взаємозв’язок дисфункції епіфізу з артеріальною гіпертензією. Вивчення літературних джерел показує, що дефіцит мелатоніну має тісний зв’язок з розвитком артеріальної гіпертензії. Актуальність дослідження даної патології полягає в тому, що зв'язок значень рівнів мелатоніну зі значеннями артеріального тиску у хворих на хронічну хворобу нирок 5 стадії, що лікуються гемодіалізом є маловивченим питанням. Наукова робота основана на опрацюванні результатів обстеження 130 пацієнтів з хронічною хворобою нирок 5 стадії, що знаходяться на лікуванні методом гемодіалізу та 20 практично здорових осіб. Вік хворих склав 58,5 [43; 66] років. В результаті дослідження встановлено, що у хворих на хронічну хворобу нирок 5 стадії, що знаходяться на лікуванні гемодіалізом, досить поширене порушення мелатонінутворювальної функції епіфізу (84,6%) та наявна артеріальна гіпертензія (78%). Аналіз результатів демонструє наявність зворотних зв’язків низьких рівнів мелатоніну із високими значеннями артеріального тиску. Додавання мелатоніну до комплексного лікування таким пацієнтам є обґрунтованим та буде предметом подальших досліджень, що знайде відображення у наступних повідомленнях.

Published: August 2020

Abstract: Until the early 20th century, the Sundanese region was considered to have no musical history, even though such information contained, among others, the Old Sundanese script. Not many researches on the history of Sundanese music have used Old Sundanese textual sources. This paper discusses aspects of instrumental music found in Old Sundanese texts including terms used to refer to music and the types of musical instruments used. The sources used are Old Sundanese texts from the pre-Islamic period between the 15th and 17th centuries AD. Several Old Sundanese musical instruments are still known and used today with or without changes. Others are no longer known. Old Sundanese musical instruments are played alone or in groups, either on a stage or a parade. Its function is to accompany entertainment and also to accompany the ritual process. The basic material for the body of the musical instrument used is generally bronze metal and wood, including bamboo.

Pandhawa Gubah sebagai Representasi Interaksi Metafisik Manusia Jawa dan Perbandingannya dengan Cheritera Pandawa Lima
Authors: Novarina Novarina 
Published: August 2020

Abstract: This research is a comparative literary study that uses Malay and Javanese versions of Mahabarata text sources. The research objects used were the text edition of Pandhawa Gubah (PG) by Sudibjo Z. Hadisutjipto and the text of Cheritera Pandawa Lima (CPL) by Khalid Hussain. The research method used is descriptive-analysis method. In the comparative study used a comparative literary theory proposed by Endraswara (2011). The results of the text comparison reveal the similarities and differences in the image of Bima figures in the Javanese and Malay versions. The equation as a whole is that both texts contain the same heroic storyline and heroic character, Bima. In addition, Indian influence is still evident in the two texts seen from the nuances of Hinduism that exist in both texts. While the difference is seen in the events that accompany Bima's struggle in achieving his victory. Based on these similarities and differences, it can be seen that the authors attempt to represent the concept of metaphysical interactions vertically and horizontally expressed through PG text.

Published: August 2020

The first case of COVID-19 originated in Wuhan, China, after which it spread across more than 200 countries. By 21 July 2020, the rapid global spread of this disease had led to more than 15 million cases of infection, with a mortality rate of more than 4.0% of the total number of confirmed cases. This study aimed to predict the prevalence of COVID-19 and to investigate the effect of awareness and the impact of treatment in Saudi Arabia. In this paper, COVID-19 data were sourced from the Saudi Ministry of Health, covering the period from 31 March 2020 to 21 July 2020. The spread of COVID-19 was predicted using four different epidemiological models, namely the susceptible–infectious–recovered (SIR), generalized logistic, Richards, and Gompertz models. The assessment of models’ fit was performed and compared using four statistical indices (root-mean-square error (RMSE), R squared (R2), adjusted R2 ( Radj2), and Akaike’s information criterion (AIC)) in order to select the most appropriate model. Modified versions of the SIR model were utilized to assess the influence of awareness and treatment on the prevalence of COVID-19. Based on the statistical indices, the SIR model showed a good fit to reported data compared with the other models (RMSE = 2790.69, R2 = 99.88%, Radj2 = 99.98%, and AIC = 1796.05). The SIR model predicted that the cumulative number of infected cases would reach 359,794 and that the pandemic would end by early September 2020. Additionally, the modified version of the SIR model with social distancing revealed that there would be a reduction in the final cumulative epidemic size by 9.1% and 168.2% if social distancing were applied over the short and long term, respectively. Furthermore, different treatment scenarios were simulated, starting on 8 July 2020, using another modified version of the SIR model. Epidemiological modeling can help to predict the cumulative number of cases of infection and to understand the impact of social distancing and pharmaceutical intervention on the prevalence of COVID-19. The findings from this study can provide valuable information for governmental policymakers trying to control the spread of this pandemic.

Efecto del clima en animales pastoreando pasto Cayman en el trópico muy húmedo de Costa Rica. La respuesta animal alpastoreo se atribuye a la oferta y a la calidad de los forrajes ofrecidos durantela época seca y lluviosa. No obstante, el comportamiento animal ante las diferentes condicionesclimáticas, durante su crecimiento como:temperatura, humedad, precipitación, viento,y sus interacciones,no se hantomado en cuenta. El objetivo principal fue el estudio de un sistema de manejo de pasturas denominado“Pastoreo Racional Voisin (PRV)”tomándoseen cuentalas épocas de clima en relación alcrecimiento de los forrajes yla respuesta animal. El PRV se ha convertido en una herramienta que comprenden bien losganaderos costarricenses. Se utilizaron para las mediciones de las ganancias diarias de pesocinco grupos de machos de engorde entre octubre 2014 y diciembre 2018. El pasto Cayman(Brachiaria híbrido)mantuvo una buena cobertura, aunque de forma paulatina,algunas áreas en particulardel sistema de producción,fueron invadidas por el pasto Ratana (Ischaemumciliare) y otras arvensesde hoja ancha. La presencia de Cayman y Ratana fue diferente entre losapartos.En cuanto a los rendimientos de estos pastos en términos de Materia Seca(MS),incrementaron con los años y variaron significativamenteentre las épocas con más lluvia y la de menorlluvia (época seca);no obstante, la oferta de forraje siempre fue alta. La ganancia diariade peso(GDP) fue diferente según la época del año independientemente de la oferta de forraje, el índice de carga de calor promedio fue de 82,3 el cual se ubicó en el rango de caliente.
