Matoa (Pometia pinnata J.R. Forst. & G. Forst.) Matoa (Pometia pinnata J.R. Forst. & G. Forst.) is one of the plants that is used as a traditional medicine for diabetes mellitus due to an imbalance between the amount of ROS and antioxidants in the body. Therefore, it was carried out in vitro to see the antioxidant and antidiabetic activity in matoa leaf extract. The extraction of matoa leaves was carried out using the ultrasonication method for 30 minutes with methanol, ethanol, and ethyl acetate as solvents. Antioxidant activity is release through DPPH free radical inhibition, through the antidiabetic potential released by inhibiting the work of the α-amylase enzyme. Phytochemical test results showed the presence of secondary metabolites in the form of flavonoids, polyphenols, tannins, alkaloids, and terpenoids. The results of the research on methanol, ethanol, and ethyl acetate extracts of matoa leaves showed high antioxidant activity with IC50 values of 6.416 ± 0.176 ppm, 8.622 ± 0.066 ppm, and 170.637 ± 4.441 ppm, respectively, but they were less potent than vitamin C as a comparison which is 1.646 ± 0.015 ppm. Inhibition of the α-amylase enzyme showed IC50 values of 91.037 ± 0.750 ppm, 105,166 ± 2,423 ppm, and 785,436 ± 11,740 ppm in each of the methanol, ethanol, and ethyl acetate extracts while the IC50 value of acarbose as a comparison was 23,479 ± 0.347 ppm. The statistical data analysis of Pearson correlation showed that it had a positive relationship between the antioxidant and antidiabetic activity of matoa leaf extract as seen from the R-value of 0.998. The higher antioxidant activity, so the higher potential for inhibition of α-amylase enzyme.

This work represents thermal study of PEO-based polymer electrolyte films that were prepared by the solution cast technique. The melting temperature Tm, glass transition temperature Tg and degree of crystallinity χc were measured by diffraction scanning calorimetry (DSC). Thermogravimetric (TGA) was used to determine the initial and final degradation temperatures. The structural was also performed to characterize the vibrational wavelength and phase characteristic (crystalline/amorphous). While the morphological study was emphasized to examine the features appearance for pure polymer electrolyte system as well as after addition salt, plasticizer and filler. The zirconium oxide particles were measured after the milling process by using the transmission electron microscopy (TEM), and the particles obtained in the range of 9 – 54 nanometer size.

In this paper, we predict the nucleation phase of as-synthesized manganese (Mn) doped cadmium selenide (CdSe) quantum dots (QDs) at an intrinsic physical size of 3 (± 0.1 – 0.9) nm via photoluminescence (PL) studies. The nucleation phase was analyzed at temporal evolution (16, 46 and 90 mins) and temperature (210, 215 and 220 ºC) below the CdSe QDs reaction temperature (210 and 215 ºC) to it reaction temperature (220 ºC). The PL spectra`s observed to be against the QDs ripening behaviour of QDs since there are no prominent red-shift of PL spectra`s. However, the intensity of PL spectra`s shows to be varied with different temperatures and times.
Transgressão e mudança de um currículo inexistente para ensino de línguas adicionais para crianças
Authors: Seccato Mariana Guedes
Published: September 2021

O presente texto tem como objetivo principal refletir sobre a elaboração de diretrizes para o ensino de línguas adicionais nos primeiros anos do ensino fundamental brasileiro. Atualmente diretrizes nacionais consolidadas para o ensino de outras línguas existem a partir do 6º ano do ensino fundamental. A principal atenção nas reflexões aqui trazidas pontua a necessidade de pensar em currículos, conteúdos programáticos e diretrizes que se baseiam nos princípios da responsabilidade linguísticas e pedagógica. Para tanto, utilizo pressupostos teóricos da obra Pedagogia do Oprimido, de Freire para embasar que a elaboração de qualquer direcionamento em âmbito educacional deve garantir a equidade de oportunidades. Diminuindo assim, as possibilidades de relações opressivas que anulam posicionamentos, visões e ações dentro das escolas. Abordo a associação entre linguagem e pertencimento ao mundo como prescrição à consideração das diversidades e compreensão do que é diferente, atribuindo ao currículo escolar a responsabilidade de discorrer sobre o direito à todos de aprender em situações contextualizadas.

Impact of board gender diversity on the financial performance of the manufacturing and service companies listed on the Amman Stock Exchange
Authors: Abbadi Sinan , Abuaddous Murad , Alwashah Ahmad
Published: September 2021

This study seeks to explore the significance of board gender diversity and its impact on the financial performance of the manufacturing and service companies listed on the Amman Stock Exchange (ASE) between 2013–2018. Prior studies have determined several benefits of female presence in the boardroom. However, gender diversity’s impact on financial performance is still unclear due to the mixed findings regarding this relation. In addition, studies about gender diversity roles in Jordanian companies’ performance are missing in the literature. Hence, in order to fill this gap, data from the listed companies was extracted from the ASE website with a total sample of 1088 companies as follows: 294 manufacturing companies (27%) and 794 service companies (73%). The results showed more males (96.2%) than females (3.8%) on the board of directors among the listed manufacturing and service companies. The manufacturing and service companies reported a mean Tobin’s Q value of 1.044 (SD = 2.164) and 1.304 (SD = 3.554), respectively. Results show that the linear regression shows that board gender diversity has a statistically significant impact on Tobin’s Q (p = 0.043) and ROA (p = 0.062). Therefore, there is a need for both the manufacturing and service companies to consider increasing the number of female members on the board for better financial performance
An assessment of corporate governance implementation in state-owned enterprises of the emerging economy
Authors: Khumalo Muzi , Mazenda Adrino
Published: September 2021

South African state-owned enterprises (SOEs) form a critical cog in the state machinery. The significance of sound corporate governance has become more pronounced as citizens demand more accountability and value in the use of public resources (Vicente, 2020). The paper utilised a qualitative desktop approach, a case study design and thematic analysis to investigate board and executive management practices in the North West Development Corporation (NWDC) corporate governance, factors hindering good corporate governance and lastly recommendations that can be offered to enhance good corporate governance. The NWDC is a regional development finance institution in South Africa, which over the years has continued to implement adverse audit outcomes (AGSA, 2019b). The thematic analysis findings revealed a direct relationship between lack of consequence management and the state of poor corporate governance in the NWDC. The lack of ethical leadership lies at the heart of this morass of SOEs in general. The study, therefore, recommends the full implementation of the existing legislative framework, the Codes on Good Governance and the anti-corruption national strategy in order to inculcate accountability in the South African public agencies that include the NWDC. The paper is relevant in addressing the Auditor-General qualified audits, which underlines the ineffectiveness of the existing SOE governance system by not inherently correlating corporate success with the presence of deeper corporate governance standards and ethical behaviour.

This study aims to determine the implementation of violin courses at Yamaha Music School Padang. The data were obtained during the learning process. Interviews were conducted to violin instructors at Yamaha Music School Padang. In addition, photos during the violin learning process at Yamaha Music School Padang were documented. Based on the research results, the implementation of music courses at Yamaha Music School Padang, especially the violin course, "seems not guided" by the concepts and principles of the Yamaha method. In fact, the materials contained in the Yamaha Music Examination Syllabus as an evaluation of learning outcomes based on YMES clearly describes the achievement of students’ learning outcomes based on YMES. The materials contained in the Yamaha Music Examination Syllabus also evaluate the “readiness” of students towards creative abilities. Likewise, the principle of Emphasis on creativity is increasingly not being noticed in music courses at Yamaha Music School Padang if it is viewed from the 'minimal' 'activity' carried out by Yamaha Music School Padang.Keywords: Implementation, Violin Course, Yamaha Music School Padang

The relevance of this study is determined by the evaluation of the ever-increasing and, as a rule, negative impact of computer technologies on the health of schoolchildren. The study aimed to investigate the features of the effect information technologies have on the well-being of high school students and to analyze the role teachers play in popularization of healthy lifestyle and reduction of the degree of influence of information technologies on health of modern schoolchildren.
Hygiene practices in children and adolescents to prevent COVID-19 transmission (Literature review)
Authors: Krylov VP
Published: September 2021

Socio-economic outcome of long-term SARS-CoV-2 pandemic poses a major health risk to children. A high number of neurological disturbances and nutrition-associated problems are reported. Hygiene is one of the most important measures to avoid the novel coronavirus infection. Children and adolescents commonly constitute a special population, as disease severity in this group significantly differs from that in middle-aged and senior groups. Lockdown and transition to remote learning result in numerous reasons for emotional stress such as a dramatically altered way of life and education, and an important reduction of physical activity. The basic hygienic measures for children and adolescents included lockdown and transition to remote learning. An altered way of life caused strong emotions and poor academic achievements. As time passes, based on numerous statistical data, we can conclude that the role of children in the infection transmission and spread is insignificant. In spite of doubtful effectiveness of transition to online learning and an abundance of negative consequences for children’s mental health, some authors report that closure of schools resulted in a reduced number of those affected and decreased mortality rate. Hand hygiene is a very important way to prevent the spread of infections. Hygiene promotion aimed at children and adolescents is lacking during the pandemic, as explanatory talks are mainly given by parents.

Published: September 2021

This paper presents the development of an automated tool called QuEEN PyService, aimed to the extraction of events voltage signals from the QuEEN distribution network monitoring system database, for advanced Power Quality analysis. The application has allowed the integration of the DELFI classifier (DEep Learning for False voltage dips Identification), recently developed by RSE, making it possible for the first time the intensive validation of the latter on a large number of voltage dips. Thanks to this tool, a comparison between the performance of DELFI and those of an older criterion based on the 2nd voltage harmonic measurement has been performed using data recorded by 61 measurement units in the period 2015-2020 The analysis has been focused on traditional PQ voltage dips counting indices as N2a e N3b. Results show that the usage of the DELFI classifier increases the N2a and the N3b by respectively the 20.6 % and 38.8% with respect to the QuEEN criterion.

Environmental issues are a major concern in society. To solve them, new technologies have appeared in the las few years, such as Renewable Energy Sources (RES) or Electric Vehicles (EVs). Nevertheless, all these technologies have a huge impact in the Electric System, and especially, in the electric grid, due to their technical characteristics. In this sense, the grid needs to evolve to assume the new electric scenario. In this context, this paper is focused on summarizing how the grid should evolve to correctly integrate these new elements into de system with a special focus on EVs, as they will be the ones with the greatest affection on the load profiles. Hence, how to integrate EVs into the grid considering charging profiles will be explained in order to design the electric grid of the future.

Published: September 2021

In order to take advantage of the low wind speed found in the Colombian territory, a gradient-based optimization process (GBA) of 2 airfoils is carried out, using the Xfoil software to evaluate the interactions. The shapes chosen will be destined for the root and for the middle zone of a blade for a small horizontal axis wind turbine (sHAWT). The blade will be created from the calculation of the chord and pitch angle with the blade element momentum methodology (BEM) and the SHAWT will be tested by CFD software to check its performance. As a preliminary result, a root-bound airfoil has been obtained with a higher performance than the airfoil used as a bases.
