Monetary Policy Strategies and Tools: Financial Stability Considerations
Authors: Goldberg Jonathan , Klee Elizabeth , Prescott Edward Simpson , Wood Paul
Published: August 2020

This paper examines potential interactions between financial stability and the monetary policy strategies and tools considered in the Federal Reserve’s review of monetary policy strategy, tools, and communication practices. Achieving the Federal Reserve’s goals of full employment and price stability promotes financial stability. A key concern, however, is that with a low equilibrium real interest rate, a low policy rate will be necessary, and in turn, these low rates may contribute to an increase in financial system vulnerabilities. Our analysis suggests that there are typically significant macroeconomic and financial stability benefits of using these tools and strategies, but there are plausible situations in which financial vulnerabilities are such that it would be desirable to limit their use. A clear communications strategy can help minimize financial vulnerabilities. Should vulnerabilities arise, they are often best addressed with macroprudential tools.
Anotaciones fenomenológicas sobre problema del yo (Ego) y la conciencia en la filosofía sartreana
Authors: Lechuga-Cardozo Jorge Isaac , Cardozo-Beltrán Arturo Alberto
Published: August 2020

Objetivo: explicar que la conciencia es exterioridad plena, es decir que en su interior no habita ninguna instancia metafísica, como lo podría ser el moi, el cogito, el inconsciente. Método: se aplicó el método de análisis, con un enfoque cualitativo, se realizó una revisión de la literatura desde una perspectiva crítica, bajo un nivel documental-bibliográfico transversal. Resultados: tras la revisión documental se encontró que la tesis sartreana “El hombre está condenado a ser libre” (1996, p.22), solo es posible si se sustenta el carácter de exterioridad en la conciencia. En otras palabras, la noción de conciencia que aparece en los primeros escritos sartreanos, en especial La Trascendencia del Ego, es la base, para que en el Ser y la Nada, se justifique el carácter inherente de libertad en el ser humano. Discusión y Conclusiones: se concluye que lo noción de conciencia en Sartre es la superación del solipsismo e idealismo propios de la tradición moderna.

O acesso de indivíduos após-acidente vascular encefálico aos serviços de fisioterapia: revisão integrativa da literatura
Authors: Sampaio Itália Castro , Machado Tácia
Published: August 2020

INTRODUÇÃO: O acidente vascular encefálico (AVE) pode causar dependência nas atividades de vida diária dos indivíduos e, para minimizar esses danos, é fundamental que o acesso aos serviços de reabilitação seja imediato e ininterrupto. OBJETIVO: Investigar o acesso à reabilitação fisioterapêutica de indivíduos após o AVE. MATERIAIS E MÉTODOS: Este estudo trata-se de uma revisão integrativa da literatura, na qual foi realizada uma busca on-line nas bases de dados Scielo, Pubmed, Lilacs, PEDro, Cochrane e Scopus De forma complementar, foram realizadas buscas secundárias nas listas de referências dos estudos analisados. A pesquisa restringiu artigos publicados entre os anos de 2009 a 2019, escritos nos idiomas português, inglês e espanhol, com descritores específicos. No total foram identificados 129 artigos, dos quais 7 foram selecionados para análise nesta revisão após aplicar os critérios de inclusão e exclusão. RESULTADOS: Com base no que foi revelado pela pesquisa, mais da metade dos indivíduos entrevistados não foram encaminhados aos serviços de fisioterapia, sendo que as principais barreiras relatadas foram a dificuldade de acesso físico-financeiro aos serviços e de dar continuidade ao tratamento. Outro dado de destaque é o pequeno percentual de usuários com problemas neurológicos identificados na rede de fisioterapia ambulatorial. CONCLUSÃO: De maneira geral, o acesso a reabilitação fisioterapêutica foi classificado como insuficiente na maioria dos estudos analisados.  É nessa perspectiva que se percebe a importância da reorganização dos serviços de saúde, ressaltando a necessidade da inserção do profissional Fisioterapeuta nas Equipes de Saúde da Família.

INTRODUÇÃO: Aspiração traqueal é utilizada rotineiramente após cirurgia cardíaca para garantir adequada ventilação. OBJETIVO: Verificar se a ausência da aspiração traqueal antes da extubação em pacientes sem sinais de secreção brônquica influencia na incidência de complicações pulmonares, além de repercussões hemodinâmicas e ventilatórias do procedimento e custos. MÉTODOS: Pacientes foram avaliados entre agosto/2012 e julho/2014, divididos igualmente em Grupo ASP (aspiração traqueal prévia à extubação) e NASP (sem aspiração prévia). Foram incluídos indivíduos com: primeira cirurgia cardíaca, idade entre 18 e 75 anos, IMC ? 30 kg/m² e sem doença pulmonar prévia. Foram excluídos indivíduos com tempo de CEC > 120 minutos, necessidade de assistência circulatória mecânica, relação PaO2/FiO2 < 200, SpO2 < 92%, tempo de intubação > 12 horas, PAM < 60 mmHg e sinais de secreção pulmonar. Variáveis hemodinâmicas, ventilatórias, complicações pulmonares e custos hospitalares foram avaliados. RESULTADOS: Foram analisados 228 pacientes (ASP= 114 NASP= 114). FC, PAS, PAD e PAM elevaram-se após aspiração e pós extubação nos grupos, retornando aos valores basais no decorrer do tempo. Não houve diferença estatística na FR e SpO2. Complicações pulmonares representaram 7,8%, sem diferença entre os grupos. CONCLUSÃO: A supressão da aspiração traqueal nos pacientes em pós-operatório imediato de cirurgia cardíaca não influenciou na incidência de complicações pulmonares e evolução clínica pós-operatória. Durante aspiração, houve alterações hemodinâmicas e respiratórias, sem repercussões clínicas, porém estas mesmas alterações ocorreram no grupo NASP após extubação, em menor intensidade. Aspiração endotraqueal sem indicação mostrou-se custosa e com desperdício de tempo dos profissionais.

Published: August 2020

In this research, it is aimed to determine the ideas of primary school teachers about the concept of gamification, the elements of gamification they use, the criteria they take into consideration while using the elements of gamification, the reasons for using them in gamification, the problems they face when using gamification and solutions to these problems. Phenomenology design, a qualitative research design is referred to in the research. The participants of the research consist of twelve primary school teachers who work at different schools and who teach different grades. In this research, semi-structured interview form, which was prepared by the researchers as a data collecting tool was used. The data acquired from the interviews done with the participants, was analyzed through content analysis. According to the results of the research, it was determined that majority of the primary school teachers perceive the concept of gamification as an educational game. Badges and leader boards were determined as the mostly used elements of gamification by primary school teachers. It was observed that the foremost criteria that primary school teachers consider while using the elements of gamification were reading books, starting reading at the first grade and success level in the lessons. Improving the success of the students and increasing their motivation in lessons were determined as the reason for using gamification elements. The foremost problem that primary school teachers face while the using gamification elements is the over-competitive behavior occurring amongst the students. As the second, the problem of regression in the students whose levels are low is stated. As for solving the problems faced, using the gamification elements taking into consideration some other actions- not success in lessons- is determined to be the most effective solution.
Will to Live: The Fulfillment of Needs for Meaning and Its Relation to Meaning in Life
Authors: ÜNAL Zeynep Merve
Published: August 2020

One of the purposes of this study is to develop and test the factor structure of a multidimensional Needs for Meaning Scale (NFMS) and another purpose is to investigate the contribution of needs for meaning fulfillment on experiencing meaning in life by using self-determination theory. Baumeister asserts that meaning in life can be established with the possession of four needs for meaning: need for purpose, need for values and justification, need for efficacy, need for self-worth. To measure NFM, 33-itemed NFMS is constructed. Meaning in life was measured through the Purpose in Life (PIL) test. The data were gathered conveniently from 355 individuals. Both the NFMS and PIL test were investigated through confirmatory factor analyses (CFA) before two structural models were tested. The data were analyzed by means of a SEM analysis using AMOS program. Three different models of NFMS were tested. CFA confirmed four dimensions of NFMS in both a first- and second-order solutions. Additionally, both structural models had a good fit to data and indicated that needs for meaning fulfillment has positive contribution on meaning in life. The fulfillment of need for purpose emerged as the most important predictor of meaning in life. The findings were discussed in the light of explanatory power of the dimensions of needs for meaning on meaning in life.

According to the Indonesian Ministry of Communication and Informatics data, at least 30 million children and adolescents in Indonesia are internet users, and digital media is currently the main choice of communication channels they use. One of the content that is the choice of users, especially children, is an interactive game. There is a strong assumption that interactive games can inhibit children's education, which makes children lazy to learn. The other side of character education is a target of the Indonesian government. Education about caring and perseverance is an important topic for children's character education. This article will discuss thematic learning media for raising children's awareness and perseverance which combines "game" and "learning" which are packaged with asynchronous models. Asynchronous was chosen because this character education still requires students to meet and discuss with teachers to find out the results of this education. This research is through a descriptive procedural research model, which outlines the steps that must be followed to produce a product. The data obtained in this design was taken by data observation, interview and documentation methods. Data observation method consists of visual data, library data and survey target audience. With the improvement of educational game design to increase children's care and perseverance, there will be an introduction, pattern and knowledge that can improve the character of children in life. This research can also be a guide for character education or one of the learning materials.

Published: August 2020

This study aimed at exploring the students’ beliefs towards reading between those who have followed ER and those who have not in the distinct level of reading ability—high, intermediate, and low level. This present study was a qualitative study concerning the students’ perception towards a particular issue. The findings show that the students’ beliefs towards reading English, for those who have followed ER with a high level of competency, remains the same as intensive reading principles. While, unexpectedly, those who have not yet followed ER at the same level have some beliefs which refer to ER principles. For the intermediate and low level for either those who have or have not yet followed ER, their principles remained the same reflecting those of intensive reading. This study contributes practically to ER practitioners in implementing ER in order that ER, within classroom activities, can run as it is by minimizing the biases and maximizing its benefits based on the outcomes, the students’ beliefs towards reading in English. Theoretically, the contribution lies at an additional confirmation that the outputs of ER, in the form of students’ beliefs, may result unexpectedly for many factors contributing to its success must really be well-monitored. The conclusion and suggestions are then attached to the end of this paper.

Published: August 2020

O solo é tridimensional e dinâmico formado por partes sólidas, líquidas e gasosas de origem mineral e orgânica que estão ligados a diversos processos ecossistêmicos. A mineração de areia causa inúmeros impactos no solo cuja recuperação necessita de manejo monitoramento dos indicadores de qualidade do solo. No presente trabalho, realizou-se o levantamento dos atributos mecânicos densidade do solo e de partículas, macro, micro e porosidade total de três áreas de manejo na Fazenda do Poço para estabelecer a eficiência do processo de recuperação por meio de avaliação estatística por análise de variância (ANOVA), teste T de Student (p < 0,05), correlação de Pearson e avaliação e atribuição aproximada das bandas da estrutura das amostras por espectroscopia no infravermelho médio com Transformada de Fourier com processamento por análise multivariada. O fragmento florestal (A4) apresentou os melhores indicadores físicos, a área A1 apresentou melhores condições que A2, similares à A4. Condições adversas impediram coleta em A3. A macroporosidade e densidade do solo foram os melhores indicadores de degradação. Foi possível atribuir aproximadamente as principais bandas no FTIR e a análise multivariada demonstra a homogeneidade do solo da área. Para reduzir o impacto da compactação é necessário complementar a presença de matéria orgânica, facilitando a ação da biota do solo com enriquecimento de espécies arbóreas com raízes agressivas para mitigar a compactação do solo principalmente em A2.
INFLUÊNCIA DE CATALISADORES DE CRAQUEAMENTO CATALÍTICO EM LEITO FLUIDIZADO (FCC) NAS PROPRIEDADES TÉRMICAS DE RESÍDUOS SÓLIDOS DE POLI(TEREFTALATO DE ETILENO)
Authors: De  Ramos Filho Florêncio Gomes , Janotti Fábio César
Published: August 2020

Devido à versatilidade e facilidade de acesso à matéria-prima, a utilização de materiais plásticos vem crescendo aceleradamente nos últimos anos em nossa sociedade. O poli(tereftalato de etileno) (PET), em especial, utilizado principalmente em embalagens, representa elevado percentual dos materiais plásticos descartados após o uso e, por isso, novos métodos de reciclagem vêm sendo desenvolvidos ao longo dos últimos tempos. Dando início a estudos que possam, no futuro, levar à viabilização do co-processamento de resíduo sólido de PET em conjunto com as cargas convencionais dos processos tradicionais de FCC para a obtenção de hidrocarbonetos líquidos e gasosos, dando assim uma destinação mais nobre ao PET pós-consumo, avaliou-se, através de termogravimetria (TG) e calorimetria exploratória diferencial (DSC), a influência de dois tipos de catalisadores industriais de FCC (CAT1 e CAT2) à base de zeolitas, que por questões de segredo industrial não será revelada a sua composição, nas propriedades térmicas do PET pós-consumo, já que o processo industrial de FCC trata-se de um processo térmico-catalítico. Observou-se que o catalisador CAT1 apresentou melhores resultados para o aspecto de formação de menor quantidade de resíduo após a decomposição térmica do polímero, levando a uma maior conversão deste em outros produtos, e o catalisador CAT2 apresentou melhores resultados no aspecto da diminuição da entalpia de fusão do polímero.

Published: August 2020

O presente trabalho teve como objetivo o estudo da influência da adição de dois tipos de cargas inorgânicas, a sílica (SiO2) e a mica muscovita, na obtenção de compósitos com resíduos de madeira plástica pós-industrial. Sendo a carga de mica, um produto natural, oriundo de mineração e a sílica, obtida por uma rota de síntese química (Método Pechini). Os materiais compósitos foram obtidos em extrusora dupla-rosca, prensados, para obtenção de filmes planos e posteriormente caracterizados por análises de densidade, dureza Shore D, índice de fluidez (MFI) e microscopia óptica. Os resultados indicam que a adição de até 10 % de muscovita não modificou as propriedades da matriz polimérica, entretanto, a adição de 10 % de sílica provocou uma redução nos valores de densidade, dureza e MFI, o que pode estar relacionado a uma fraca interação polímero-carga. Pelos espectros de FTIR pode-se inferir que não há interação química entre a matriz e as cargas utilizadas.

Published: August 2020

O aço é um dos materiais metálicos mais utilizados atualmente. Em virtude da importância econômica e industrial do aço no desenvolvimento tecnológico, existe uma motivação contínua na proteção anticorrosiva destes materiais, destacando-se a importância da redução de custos e a relação custo-benefício. Este trabalho tem como objetivo realizar uma avaliação da influência do meio sobre a corrosão do aço estrutural ASTM A-36, para tanto foram utilizados meios eletrolíticos em pH neutro, contendo íons cloreto e íons sulfatos; pH básico (hidróxido de sódio) e pH ácido (ácido clorídrico). Este estudo mostrou, claramente, que na solução de NaOH 0,1 M, a taxa de corrosão foi significativamente menor em relação aos demais eletrólitos estudados, não somente nas primeiras horas, mas após períodos mais longos. Foi observado também que em meio neutro a taxa de corrosão é significativamente menor que em meio ácido mesmo na presença de íons cloretos.

The Withania coagulans a rare species, is not studied much for its actions on anxiety except in late seventies where it was explored for neuropsychopharmacology. Thus, it was thought commendable to explore the anti-anxiety activities of aqueous extract of Withania coagulans fruits in swiss albino mice using elevated plus maze test.Methods: Elevated plus maze (EPM) test was used for evaluating the anti-anxiety action of Withania coagulans fruits’ aqueous extract. If the extract had anti-anxiety action, then it was expected that the time spent in the open space would increase and that in the closed space would decrease. This increase in time in the open space, if found statistically significant, was considered for antianxiety action.Results: There was statistically highly significant (p value <0.001) association observed between the aqueous extract of Withania coagulans fruits with antianxiety action in the swiss albino mice by elevated plus maze test.Conclusions: The aqueous extract of Withania coagulans fruits did prove the antianxiety effect in the swiss albino mice by elevated plus maze test.

Background: Inadequate understanding and performance of drug administration using metered-dose inhaler (MDI) in paediatric population affects therapeutic outcome. Hence, this study aimed to evaluate the impact of two educational interventional methods for usage of MDI in paediatric patients of bronchial asthma.Methods: This prospective, interventional study was done in paediatric asthma patients who were prescribed drugs with (MDI) with/without spacer at outpatient department of pediatrics. Patients were divided in group A (video) or group B (leaflet) as per random table method and method to use MDI was assessed by using checklist as per WHO guide to good prescribing at baseline. Investigator taught the technique by a video (group A) and leaflet (group B) to the selected population. Patients were followed up after 15 days and assessed for use of MDI using the same checklist. Data were analysed by using paired and unpaired ‘t’-test.Results: A total of 100 pediatric asthma patients were included in study group A (50) and group B (50). The average no. of steps (WHO checklist) followed was significantly improved at post intervention in both group A (with spacer, p<0.0001) as well as B (without spacer, p<0.05). Although average no. of steps followed were more in group A, no significant difference was found between two groups after intervention.Conclusions: As video is an audio-visual method of demonstration, and hence help us memorise the step of inhalational technique in pediatric patients. Repeated demonstration/education to patients/caregivers may improve the method of MDI usage.

Published: August 2020

Background: This study was aimed in assessing the prevalence and pattern of CAM in patients with dermatological disorders.Methods: This cross sectional study was carried out at outpatient department of Dermatology at tertiary care teaching hospital. Data was collected with help of questionnaire which contained sociodemographic details and details of use of CAM if any by the attending patients. Data was analysed for sociodemographic and clinical character, pattern of use of CAM, source of information and reasons for using CAM.Results: Mean age of participants was 29.29±20.25 (Mean±SD) years and 102 (46.54%) users were women. Highly educated patients (49.25%) were the most frequently CAM users. Below 20 years (57.84%) youngsters were the frequent CAM users. About 45.19% patients were belonging to rural area of community. Acne vulgaris was the commonest condition for CAM use. Folk medicines (70.73%) were the most frequent used CAM. Advised by friends/relatives was the commonest source of information. About 80.49% patients had not informed to their physician about the use of CAM. None of the patients had knowledge of adverse effect of CAM.Conclusions: Use of CAM is very common in dermatological disorders, youngsters and literate were the most common CAM users. Combined administration of herbs with prescription drugs may increase or decrease the pharmacological or toxicological effects of either compound.

Background: To study about the prevalence and anti-microbial susceptibility pattern of methicillin resistant Staphylococcus aureus (MRSA).Methods: Totally 110 non-repetitive Staphylococcus aureus isolates were enrolled in this study. Isolates from different clinical specimens like pus and blood obtained from patients in tertiary care hospital and Staphylococcus aureus was identified by conventional phenotypic methods. Complete antibiotic susceptibility testing of all MRSA isolates was determined by Kirby-Bauer disc diffusion method.Results: Out of 110 isolates of S. aureus 60 were found to be methicillin-resistant Staphylococcus aureus (MRSA). The prevalence of MRSA was 54%. Out of 60 isolates, male patients 37 (63%) and female patients are 22 (37%). Maximum numbers of isolates 25 (41.6%) were from the age group of 51 to 60 years. Among these 60 isolates, all of them were found to be resistant to penicillin and oxacillin. In contrast, 98% of the isolates were found to be sensitive to linezolid. The sensitivity to chloramphenicol 70%, co-trimoxazole 60%, amikacin 58%, clindamycin 43%, ciprofloxacin 38%, erythromycin 25%.Conclusions: The observed prevalence rate was 54%. Linezolid showed the best therapeutic outcome against MRSA. Active screening plays an important role in control of MRSA.

Background: This study was done to study the drugs used in wheeze associated lower respiratory infected paediatric patients in tertiary care teaching hospital.Methods: Sample size was calculated as 78 and patients were selected based on the inclusion and exclusion criteria. The study was a prospective observational study and conducted in Department of Pediatrics, Rajah Muthiah Medical College and Hospital (RMMCH), Annamalai University.Results: Our study shows that male children (63%) are affected with more than female children (37%). The most frequently prescribed drugs are antibiotics (96%), antipyretics (63%), expectorants and antitussives (54%) followed by beta adrenergic agonist (46%), beta adrenergic agonist with anticholinergic combination (14%) corticosteroids (18%). Our study also shows wheeze associated lower respiratory infection (WALRI) in children were significantly associated with bacterial infections (72%).Conclusions: Our study concluded that antibiotics and antipyretics are the most commonly prescribed drugs for WALRI followed by expectorants and antitussives, beta adrenergic agonist, corticosteroids, beta adrenergic agonist with anticholinergic combination. Most of the treatment strategies are adopted from Standard Treatment Guidelines (STG) and World Health Organisation (WHO). The average number of prescribed drugs per encounter was more than that of WHO standards. The percentage of encounters in which an antibiotics and injections was higher than the ideal WHO standards it leads to anti-microbial resistance and costly forms of drug therapy.

Authors: Ahsan Marya , Mallick Ayaz Khurram
Published: August 2020

As the world races to find the solution to the COVID-19 pandemic, an investigational agent which has triggered worldwide interest is remdesivir. Though failing clinical trials for treatment of Ebola virus disease, remdesivir has shown efficacy in numerous viral studies involving SARS-CoV-2. Reports from compassionate use of remdesivir in hospitalized patients of COVID-19 have been promising. But the real picture about the safety and efficacy of remdesivir can only be known after completion of randomized clinical trials. In this review, we aim to highlight the salient features of pharmacokinetics and pharmacodynamics of remdesivir known so far and its plausible role in management of COVID-19. We searched the PubMed database and Google Scholar for published literature using the key words: remdesivir, human coronavirus, novel coronavirus, COVID-19, SARS-CoV 2, mechanism of action, pharmacokinetics, pharmacodynamics and compassionate use till 1st May 2020. The U. S. national library of medical trials registry was searched for ongoing trials with remdesivir among patients of COVID-19. Remdesivir is a prodrug of a nucleoside Analog that inhibits RNA replication by binding to viral RNA dependent RNA polymerase. It is being employed in many global phase-3 clinical trials for evaluating the efficacy and safety of the drug in patients of COVID-19.

Published: August 2020

Background: The acute metabolic complications of diabetes consist of diabetic ketoacidosis (DKA), hyperosmolar non-ketotic coma (HNC), lactic acidosis (LA), and hypoglycemia. All of these are associated with significant morbidity and mortality. These can easily be prevented by early recognition and prompt management. Therefore, this study was conducted to assess the clinicopathological spectrum of acute complications of diabetes mellitus type II.Methods: This observational, analytical study was conducted on 100 patients aged more than 18 years admitted in the ICU with acute complication of Diabetes mellitus Type II. Medical history was recorded. Physical examination and investigations were done and recorded.Results: The mean age of the study population was 55.26±13.13 years. Hypoglycemia was more common (63%) than DKA (37%). Fever and sweating had the overall highest incidence (and were more in patients with hypoglycemia) while stupor, nausea and abdominal pain had the lowest incidence (and were more in patients with DKA). On examination, only one patient of DKA was drowsy. Mean temperature, pulse and respiratory rate were higher in the patients having DKA while blood pressure was higher in patients having hypoglycemia.Conclusions: It can be effectively concluded from the present study that DKA and hypoglycaemia have a broad spectrum of clinicopathological features. But the incidences vary widely. This may help in early recognition of the impending complication and thereby enabling prompt management of the same, reducing the associated morbidity and mortality.

Background: Chronic kidney disease (CKD) is one of the vital health problems worldwide leading to increased global morbidity and mortality. Thyroid dysfunction including hypothyroidism, hyperthyroidism and non-thyroidal illness has been reported in CKD patients. This study was conducted to determine the prevalence of subclinical and overt hypothyroidism among chronic kidney disease patients. This study also tried to correlate thyroid function abnormalities with severity of renal failure.Method: In this observational and cross sectional study, 100 patients of CKD who were admitted in Department of Medicine, Rajendra institute of medical sciences, Ranchi were studied for thyroid function abnormalities. Result: This study found that glomerular filtration rate (GFR) is positively correlated with serum T3 and T4 level (i.e. with decreasing renal function both T3 and T4 levels decreased). Serum creatinine levels were negatively correlated with serum T3 and T4 level.Conclusions: From this study it was established that CKD is associated with thyroid dysfunction characterized by low serum fT3 and fT4 with high TSH in some cases.
