Authors: Cruz Rosângela
Published: June 2022

Apresenta-se no Artigo o resultado da Pesquisa realizada por meio de entrevista e de pesquisa bibliográfica com objetivo de investigar qual a percepção dos professores do Pré II da Escola de Educação infantil “Construindo o Saber” sobre a lei 10.639/03.A escola recebe crianças com faixa etária de 1 à 6 anos. Conclui-se que dos cinco professores pesquisados dois conheciam o assunto e já havia estudado um pouco sobre o assunto e tinham até conhecimento da Lei Federal nº 10.639, de 2003.  “Já os outros três responderam que não tinham conhecimento da lei e para que trabalhar isso na educação infantil se as crianças não se prendiam a esses detalhes. Nota-se que se faz urgente incluir no currículo da escola a temática sobre as Relações Raciais na Sociedade Brasileira, uma vez que já é obrigatoriedade garantida especificamente na Lei 10.639/2003 e nas Diretrizes Curriculares Nacionais para a Educação Infantil de 2010. Sendo assim sinalizam a necessidade de um trabalho de formação contínua dos professores, para que sejam capazes de compreender a Lei 10.639/2003 sobre as Relações Raciais na Sociedade Brasileira, e comecem a aceitar o diferente lembrando que somos todos iguais.
A utilização de dados sobre a Covid-19 por webjornais brasileiros
Authors: Santos Karla , Saar Cláudia
Published: June 2022

O jornalismo de dados busca averiguar informações relevantes em grandes volumes de dados que por vezes estão escondidas ou disfarçadas entre uma avalanche de informações que, por falta de análise ou aprofundamento, não são trazidas a tona, impossibilitado uma ampla divulgação e discussão na esfera pública. Analisar dados através de técnicas como data mining, scraping, visualização e outras, possibilita informar a população de maneira mais assertiva e direta, uma vez que busca-se informações públicas em ambientes pouco explorados. Levando em consideração essa força crescente no jornalismo e as alterações mundiais proporcionadas pelo coronavírus, além do processo de desinformação e proliferação de fakenews no Brasil nos últimos anos, o presente artigo busca elucidar, como o suporte do método data mining e análise de conteúdo podem ajudar a aflorar perspectivas de análises mais apuradas sobre problemas mediáticos de informação sobre a pandemia da Covid-19.

Authors: Silva Suzana , Silva Rejane
Published: June 2022

O presente artigo objetivou compreender as representações sociais no processo de formação inicial de professores de Música da UFPE. Adotamos como aporte teórico metodológico a Teoria das Representações Sociais (TRS), formulada por Serge Moscovici em 1961 e a Teoria do Núcleo Central (TNC) delineada por Jean Claude-Abric. Norteada pelo enfoque qualitativo online, a pesquisa consistiu no emprego de duas etapas distintas, ou seja, a Técnica de Associação Livre de Palavras (TALP) e as entrevistas semiestruturadas. O material foi analisado com o auxílio do software IRAMUTEQ e as entrevistas semiestruturadas com o emprego da Análise de Conteúdo proposta por Bardin (1977). Os resultados da primeira etapa revelam que a estrutura interna das representações sociais dos estudantes se organiza em torno da categoria disciplinar, apontando que a ênfase da formação ainda se fundamenta na noção do habitus conservatorial. A partir da análise de similitude identificamos que o núcleo central é constituído pelas categorias pedagógica e afetiva.

Authors: Rojas Rosangel , Yepez Jose , Korzenowski Christa , Beraldin Ronaldo
Published: June 2022

The purpose of this study was to investigate the mechanical characteristics of Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) under compression uniaxial loading conditions, using waste in the mixture. UHPFRC is a class of cementitious material with high durability and strength, limited to a minimum value of compressive strength of 150 MPa. The difference with traditional concrete lies mainly in the post-peak behaviour that occurs due to the presence of fibres, which are responsible for ensuring the ductile behaviour of the material. Uniaxial compression tests on twenty cylindrical specimens were carried out and tested after 28 days of curing, with a percentage of steel fibres of 1% at a displacement loading speed of 0.5 mm/min. The mixture design that was used allowed to manufacture a thixotropic material, characterized by a compressive strength and an average modulus of elasticity of 150.89 MPa and 47.71 GPa respectively. A simple production process was used, including Ground Granulated Blast Furnace Slag (GGBS) as the main sustainable material and as partial substitute for cement. Curves for design and structural analysis were plotted and compared with the average experimental curve and with other research consulted in the literature, including the elastic and inelastic behaviour of the material.

Authors: Nuari Nian Afrian , Rahman Handono Fatkhur , Wahid Abdul Hamid
Published: June 2022

Patients with diabetes must be monitored for hyperglycemia due to the risk of macrocellular and microcellular complications. High blood sugar levels force the kidneys to work harder to filter blood, which results in renal leakage. The objective of this study was to establish a relationship between glycemic control, management adherence, and hemoglobin level in patients with type 2 diabetes. This study employed a correlational design with a cross-sectional approach and a sample size of 72 respondents selected using purposive technique. Compliance with diabetes mellitus, which includes diet compliance, exercise compliance, medication compliance, and blood sugar monitoring compliance, is strongly correlated with glycemic control levels. Completely contrary, there was no link between hemoglobin levels and adherence to treatment. Microcellular processes of renal function are linked to the interaction between glycemic control and hemoglobin levels.

Published: June 2022

Essentially, translation is not simply a transfer of every word with its equivalent in the target language, but rather a transfer of the rules of the language that communicate the information and the transfer of the same information and the writer’s thought, culture and style as well. However, theories differed in translation on how to transfer this information from the source to the target. The trinity of translation: literal or word by word, free (significant) and faithful translation. The aim of this article is to discuss evaluative idioms in English and Arabic to show difficulties that form issues for translating idioms—from a variety of perspectives, focusing mainly on Moon’s 1998 approach and on Abdou’s 2012 study of Arabic idioms. Furthermore, to show the comparison between evaluative idioms in the two languages is meant to reveal differences and potential difficulties for translators translating from Arabic into English and vice versa, focusing mainly on Moon’s 1998 approach and on Abdou’s 2012 study of Arabic idioms. Furthermore, to show the comparison between evaluative idioms in the two languages is meant to reveal differences and potential difficulties for translators translating from Arabic into English and vice versa.

L’Africa verso COP27 Una riflessione alla luce della Giornata della Terra
Authors: Fiamingo Cristiana
Published: June 2022

A hopeful World is wondering whether COP27, to be held next November in Sharm El-Sheikh (Egypt), has the potential to foster the much-needed change of mindset that determined the disillusion of the previous International Conferences organized by the UNFCCC, as the regional mid-term MENA conference on climate change, held last March in Dubai, seemed to stagnate in lamentations, instead of steering into action. In the meantime, Africa is going through an escalation among syndemics, diminished access to food, and local crises fuelled by climate change, whose ticking bomb is rhythmed by floods and droughts, while the new need of the global North for energy supplies could determine economic opportunities but also negative impacts on African decarbonization and mitigating actions. There is a shared concern on whom and how to push for immediate political pressures in order not to lose the little thrust that we had gained.
Application of Cyperus esculentus oil in the development of sustained release diclofenac sodium-loaded nanostructured lipid carrier
Authors: Chime Salome
Published: June 2022

The aim of the work was to develop sustained release diclofenac sodium nanostructured lipid carrier (NLC) using tigernut oil (TNO), solid lipids and polyethylene glycol 4000 (PEG 4000) and to evaluate the properties of the formulations. Structured lipids containing tiger nut oil, Softisan®154 and Phospholipon® 90H at varying ratios were prepared by fusion and used as the lipid carrier in formulating the NLC. PEGylated lipid carriers were also employed and the physicochemical properties of these formulations were studied using standard methods including particle size and polydispersity index, encapsulation efficiency, loading capacity and drug release. The results revealed some monodispersed nano-sized formulations that were stable over time. Particle size ranged from 75.22 ± 22.72 nm to 78.11 ± 32.73 nm. High encapsulation efficiency of about 92 % was obtained confirming the suitability of the TNO based carrier.  In vitro drug release in simulated intestinal fluid (pH 7.2) revealed that PEGylated diclofenac sodium-loaded NLC exhibited significantly higher sustained release properties than the non-PEGylated formulations (p <0.05). The results of the drug release kinetics models revealed that the NLC followed a mixed order release kinetic. Hence, the findings in this work showed that TNO could be used as a lipid carrier matrix in combination with other solid lipids for the development of sustained release diclofenac sodium-loaded nanostructured lipid carrier.

“Switching to the Online MA TESOL Program”: Experiences and Decision-Making Processes of International Learners
Authors: Dos Santos Luis Miguel
Published: June 2022

The COVID-19 pandemic changed the curricula and mode of instruction for many postgraduate taught and research programs. Before the pandemic, many MA TESOL programs included on-campus tutorials as requirements, as the curricula were designed based on on-campus activities. However, as the United Kingdom restricted face-to-face teaching due to social distancing, most of the courses were switched to online learning platforms during the pandemic. Although most courses returned to on-campus teaching during the 2021/2022 academic year, a group of East Asian international students decided to continue their MA TESOL program online as an alternative option. The purpose of this study is to understand the experiences and decision-making processes about this group of MA TESOL students and their decisions to finish their degrees via the online completion option. In line with social cognitive career and motivation theory, the results indicated that flexibility, career development through online learning options, and concerns about job security were the main three themes that arose within this group of students. The outcomes provide suggestions to university leaders and program directors in regard to developing additional online courses and programs to meet the needs of adult and postgraduate students who cannot attend on-campus courses, particularly MA TESOL learners.

Randomized Trial of Postoperative Venous Thromboembolism Prophylactic Compliance: Aspirin and Mobile Compression Pumps
Authors: Dietz Matthew J. , Moushmoush Obadah , Frye Benjamin M. , Lindsey Brock A. , Murphy T. Ryan , Klein Adam E.
Published: June 2022

Background:

Aspirin, as a routine venous thromboembolism (VTE) prophylaxis, is approved along with pneumatic compression pumps by the American College of Chest Physicians. We assessed compliance of aspirin and pump use after total joint arthroplasty.

Methods:

A randomized trial of aspirin alone or aspirin/mobile compression pumps after total joint arthroplasty was performed. Aspirin and pump compliance, VTE events, and satisfaction with pump use were collected. Compliance was assessed through an internal device monitor and drug log book. Patients were also contacted 90 days postoperatively for reported symptomatic VTEs.

Results:

Each group had 40 patients and greater than 94% compliance with aspirin use, with no difference between groups (P = 0.55). Overall pump compliance during the first 14 days after hospital discharge was 51% (SD ± 33), which was significantly worse than aspirin compliance at 99% (SD ± 4.1) (P < 0.0001). Only 10 patients were compliant (>20 hr/d) with recommended pump use throughout the entire recommended period. There was no notable association between aspirin compliance and VTE within 90 days. There was no notable association between pump compliance and VTE at 90 days. However, average pump use compliance was 20% in patients with VTE and 54% in patients without VTE within 90 days. With the numbers available in this compliance study, there was no significant difference (P = 0.11).

Discussion:

Aspirin compliance was notably greater than pump compliance. In this study, we found that pump compliance was not associated with lower VTE risk. In fact, no increased risk was recognized in patients with an average pump usage of >50%. Further study is warranted to define the duration of pump use required for clinical significance. The recommended use of compression pumps should continue to be examined.

Published: June 2022

Background: The COVID-19 pandemic has become a major cause of stress and anxiety worldwide. It has generated stress among people from all sections of society, especially to workers who have been assigned to cater to healthcare service or those constrained to secure daily essential items. Yoga practice is actively sought to achieve reduced anxiety and stress so that improved sleep may positively impact immunity. Objective: The aim of this cross-sectional study was to determine whether those who practice Yoga during the COVID-19 pandemic have lower levels of stress, anxiety, and depression than those who do not. Methods: The sample consists of 51 females who have been attending Yoga sessions for many years and who continued this practice during the COVID-19 pandemic twice a week. The control group consisted of 50 non-Yoga respondents. The survey was conducted during April 2021. The Revised Event Impact Scale (IES-R) (4) and the Brief Symptom Inventory (BSI) (Derogatis, 1993) were used to assess stress. Student T-test was used to check the statistical significance of differences. Results: In our research yoga practitioners show a statistically significantly lower average severity of stress symptoms compared to those who do not practice yoga on 5 of the 6 stress indicators shown. The only statistically significant difference was not obtained on the measure of total number of symptoms (PST). Conclusion: The results suggest that yoga practice during COVID-19 pandemic is associated with lower levels of stress, anxiety and depression.
Anticonvulsant property of celecoxib in maximal electroshock seizure: Correlating the role of inflammation in pathophysiology of epileptic seizures
Authors: Jain Raina , Khare Neeraj , Jain Ashish
Published: June 2022

Background: Epilepsy is an abnormal excessive electric neuronal activity and always represents by recurrent seizures. There is positive feedback cycle between epileptogenesis and brain inflammation. It has been proved that an inflammatory enzyme, cyclooxygenase (COX) (especially isoform-2, a constitutive enzyme), expressed in some important parts of the central nervous system and is responsible to induced inflammation locally and having seizurogenic property.

Aim and Objective: The goal of this study was to see if celecoxib (a selective COX-2 inhibitor) could reduce the maximal electroshock seizure (MES)-induced seizures in mice.

Materials and Methods: Celecoxib injected intraperitoneally in two different doses 5 mg/kgb/w and 10 mg/kg b/w, in albino Swiss mice and in two different phases. MES was elicited and length of different phases was noted. Length of tonic hindlimb extension was considered as indicator of anti-epileptic activity.

Results: Celecoxib, when given intraperitoneally, exert significant reduction in the duration of THLE. This action of celecoxib strongly suggests the involvement of inflammation in the pathophysiology of epilepsy.

Conclusion: The findings are suggestive of the therapeutic significance of celecoxib, as a future antiepileptic agent for seizure management.

The phenomenon of volunteer activity is actively studied by psychologists and sociologists from different countries. Despite the fact that the interpretation of volunteering has some distinctive features due to cultural differences, they do not contradict each other in general. The greatest interest is aroused by the motives and values of volunteers, the study of which has become significant in sociological and psychological research over the past decade. This article presents studies of the motives and values of Russian volunteers.
The Impossible Language of Psychoanalysis
Authors: Motsinova-Brachkova Milena
Published: June 2022

Psychoanalysis, which has emerged as a method of healing through speech, is constantly changing because it takes into account the changing symbolic order and the emergence of an understanding of the unconscious other than what it is based on. In the beginning, the analysis of the unconscious in the Freudian sense is achieved through free associations and slips. Jacques Lacan’s early teachings introduced the idea of the unconscious structured as language, and the understanding of the symptom as a metaphor, and the Name-of-the-Father as the linguistic formula of the Freudian Oedipus complex. The latest, most difficult part of Lacanian psychoanalysis and its full development by Jacques-Alain Miller in the 21st century focuses on the analysis of parlêtre / the speaking being and on the idea of a syntоm that marks the enjoyment of the speaking body, abandoning the concept of language.

The recent investigation was carried out to determine the effect of different gamma-ray doses and 900 W (2450 MHz) microwave radiation with various exposure times, separately or in combinations, on the yield, yield components, and chemical properties of guar (Cyamopsis tetragonoloba), as well as, to detect variation induction. The cDNA-SCoT technique was used to obtain molecular markers related to some traits. SSR technique was used to sequence the target fragment related to plant height. Gamma-ray doses of 150 and 250 Gy alone, and in combination with 900 W microwaves irradiation applied with different duration or time span (1, 2, 3, and 4 min) influenced the plant height significantly, as well as, number of tillers plant-1 and fresh and dry forage yield, and fresh and dry leaf stem-1 ratio. In the second sample, seed yield at harvest time, e.g., pods plant-1, weight of pods plant-1, whole plant dry weight, number of seeds pod-1, length of pod, 100-seed weight, and seeds yield were affected by irradiation with different and varied responses. In the M1 generation, the 18 SCoT primers produced 327 bands ranging between 151–2895 bp in size, out of which 282 were polymorphic (86.24%). In the M2, the 18 SCoT primers produced 328 bands ranging between 212–2661 bp in size, out of which 299 were polymorphic (91.16%). The M1 and M2 generations exhibited 89 positive and 39 negative bands, which could be used as marker assisted-selection in response to treated guar plants with different gamma ray doses, separately or in combinations with microwave treatments.

Results of the study proved that phytoremediation can be a promising technique to treat cadmium (Cd)-contaminated soil. Four bacteria types were isolated from the soil; two are autotrophic and others are heterotrophic. Autotrophic bacteria were dominant in soils with 42 mg Cd Kg-1. The total count and diversity of both bacteria types decreased with the increase of Cd in media and reached their minimum limit of tolerance at 60 mg Cd L-1 in terms of the heterotrophic bacteria, while the minimum limit of tolerance in the case of autotrophic bacteria was at 110 mg Cd L-1. The four isolates can form biofilms that ranged in thickness between 2.8–4.3 mm. The tolerant isolates belong to Rhizobium leguminosarum, Pseudomonas fluorescens, Actinobacteria, and Corynebacterium. Shoot and dry weight significantly varied according to the changes in Cd concentrations and isolate types. The level in either shoot or root exceeded critical levels, however, its concentration was higher in the root compared with the shoot. The effect of Cd on broad bean plants began at 80 and 100 mg Cd L-1. The broad bean plant was resistant to growing in the contaminated area by Cd even at 120 mg Cd Kg-1 DW. The presence of heterotrophic bacteria was noticeably useful for autotrophic bacteria, as well as, for enhancing Cd resistance. The study showed that cooperative phytoremediation could be a safe and active technique to apply in the field soil contaminated with heavy metals.

Estimating combining ability helps to evaluate genotypes and determine the nature and degree of gene activities. This study aimed to identify the best parental genotypes and superior hybrids of aromatic rice using a line × tester mating design. Five CMS (cytoplasmic male sterility) lines and four testers of local and exotic origins of aromatic rice were studied in this experiment. The unweighted pair group method with arithmetic mean (UPGMA) cluster analysis revealed genetic variability among the studied CMS and restorer lines. The analysis of variance showed that parental lines, testers, and their line by testers populations had enough genetic variability. Five out of 20 hybrids found positive heterosis for grain yield, and the hybrid BRRI1A × BUdhan2R had the maximum heterosis. In terms of the agronomic traits evaluated, specific combining ability (SCA) effects were higher than general combining ability (GCA) effects. Genotypes IR58025A, BRRI1A, and BUdhan2R were identified as superior parents based on their performances for yield traits and GCA effects in the desired direction. IR58025A × BUdhan2R and BRRI1A × BUdhan2R were chosen as promising genotypes due to their highest grain yield, heterosis, and desirable SCA. Low ratios of σ2gca/σ2sca and (σ2D/σ2A)1/2, and low to high estimations of narrow-sense heritability indicated that both additive and non-additive gene effects predominated in the inheritance of the studied traits. Pearson's correlation showed that among the 10 studied traits, grain yield plant-1 was highly significant and positively correlated with flag leaf area, spikelet fertility (%), and filled grains panicle-1, as well as, significant and negatively correlated with days to flowering and days to maturity. Superior parental genotypes and hybrids that have been identified can be employed as donor parents to improve the grain yield in aromatic rice.

Two field experiments were carried out on a private farm at Wadi El-Natrun (latitude of 30.48° N and longitude of 30.50° E), Beheira Governorate, Egypt, in the 2019–2020 and 2020–2021 seasons, to find out the effect of adding zeolite as a soil conditioner and potassium fertilizer on growth, yield, and quality of sugar beet crop (Beta vulgaris L. var. saccharifera) grown in sandy soil conditions. The present work included 12 treatments, which were the combinations of four zeolite levels (Zero, 476, 952, and 1,428 kg ha-1), and three levels of potassium in the form of potassium sulfate (119, 178.5, and 238 kg K2SO4 ha-1), which were added as a soil application. The treatments were arranged in a complete block design in a split plot with four replications. The results showed that higher values of the photosynthetic pigments, root diameter, fresh and foliage weights plant-1, as well as, sucrose and extracted sugar percentages, quality index, yields of the root, top, and sugar ha-1, were obtained by adding 1,428 kg zeolite, compared with the other levels of zeolite, in both seasons. However, sodium, alpha-amino N contents in the root, and sugar lost to molasses% were insignificantly affected by zeolite rates in both seasons. Application of 238 kg K2SO4 ha-1 significantly resulted in the highest values of photosynthetic pigments, root dimensions, sucrose%, and root potassium content. In addition, extracted sugar %, quality index, root, top, and sugar yields ha-1 were increased compared with the other lower K-sulphate levels in both seasons. On the contrary, sugar lost to molasses% was insignificantly affected by applied potassium sulfate in both seasons. The maximum values of root diameter, fresh weight, yields of root and top ha-1 in both seasons, and also sugar yield in the second season were produced from the interaction between applying 1,428 kg zeolite and 238 kg potassium sulfate ha1.

The oilseed crop improvement for Brassica rapa L. (field mustard) is considered to be important in respect of yield production coupled with unsaturated fatty acids of the existing cultivars. Hence, the genetic diversity, and nutritional components of 14 B. rapa cultivars were evaluated based on their yield attributes and fatty acid profiles at the Sher-e-Bangla Agricultural University, Dhaka, Bangladesh. These 14 B. rapa cultivars differed significantly and were grouped into five diversified clusters. The highest intra-cluster distance was found in cluster II (2.43), while the highest inter-cluster distance was found between clusters II and V (20.41). In the fatty acid profile, the maximum threshold acceptable level (<7%) of saturated fatty acids for human consumption was found in Sonali Sarisha and BARI Sarisha-14. The total monounsaturated fatty acids viz., oleic, eicosenoic, and erucic acid ranged from 62.74% in BARI Sarisha-15 to 69.51% in Sonali Sarisha. The highest oleic acid and eicosenoic acid were obtained from the local variety, Maghi (21.06%) and Improved Tori (9.08%). The highest essential linoleic and linolenic acids were found in BARI Sarisha-15 (17.10%) and Improved Tori (8.16%), respectively. However, the local cultivar Maghi, containing the highest oleic acid (21.06%) has the lowest erucic acid (35.53%). On the other hand, BARI Sarisha-14 contained the lowest oleic (17.22%) and the highest erucic (44.02%) acids. The negative and strong correlation also reinforced the reverse relationship between oleic and erucic acids. Similarly, both linoleic (-0.497) and linolenic (-0.443) acids also showed a negative correlation with erucic acid. As a whole, BARI Sarisha-14, BARI Sarisha-15, Maghi, Sonali Sarisha, and Improved Tori could be selected as potential parents for a hybridization program to breed potential recombinant lines with higher oil content and healthier unsaturated oleic and linoleic fatty acids.

The existence of different views or beliefs will be difficult to avoid friction or conflict. Conflict of belief is a dynamic that occurs in people's lives in Indonesia. Religious instructors are very risky and important jobs in improving the quality of religious life in accordance with their beliefs and beliefs as well as increasing religious harmony in their respective fostered areas so that no more problems arise due to differences in views based on religion. An instructor must have a good character like the character of the Panca Pandavas in the Mahabharata epic, this character can be guided by Hindu religious instructors in carrying out their duties and functions. The epic Mahabharata is one of the stories contained in Itihasa about the journey of the Kuru people with the core story being in the conflict between the Panca Pandavas and the Kauravas. The Panca Pandavas themselves are children born from the incarnation of the gods with almost perfect characteristics. It is this trait that must be imitated by Hindu religious educators in order to become instructors who have characters such as wise characters, firm in their views, honest, brave, loyal, gentle, polite, patient, confident, obedient, steadfast, smart and thorough.
