Authors: Fitriana Diana , Wijanarko Dwi Seno
Published: May 2023

This study aims to discover and analyze how the Financial Services Authority regulations and the Bank Indonesia regulations relate to information technology-based money lending and borrowing activities in the implementation of fintech peer-to-peer lending, particularly for Paylater users who feel disadvantaged by seeing what it looks like and how the explanation of the regulations regulate fintech, so that many consumers continue to feel disadvantaged. In addition, how is the supervision provided by the Financial Services Authority to administrators of peer-to-peer lending activities in accordance with the governing laws and regulations? In this study, we used a normative juridical research type with a statutory approach (the statute approach) and a case approach (the case approach) by conducting a literature study. The results of this study explain that the form of regulation on fintech peer-to-peer lending is regulated in Financial Services Authority Regulation Number 77/POJK.01/2016 concerning information technology-based money lending services and Bank Indonesia Regulation Number 19/12/PBI/2017 concerning the implementation of financial technology, and Government Regulation Number 82 of 2012 concerning the implementation of electronic systems and transactions, with arrangements for organizers to record, a regulatory sandbox, registration, and licensing to the Financial Services Authority. That the cases that occurred, as seen through the existing arrangements, continue to fail to accommodate the cases encountered by consumers. Regarding this action, the supervision provided by the Financial Services Authority is in the form of pre-operational supervision and supervision during operations, but there are obstacles in supervision, namely the absence of the Financial Services Authority's fintech department to resolve all problems from the Financial Services Authority's side, and at the supervision stage, it is not able to adapt to innovation so quickly.

Prospect of nanomaterials as antimicrobial and antiviral regimen
Authors: Chakraborty Ashok , Diwan Anil , Tatake Jayant
Published: May 2023

In recent years studies of nanomaterials have been explored in the field of microbiology due to the increasing evidence of antibiotic resistance. Nanomaterials could be inorganic or organic, and they may be synthesized from natural products from plant or animal origin. The therapeutic applications of nano-materials are wide, from diagnosis of disease to targeted delivery of drugs. Broad-spectrum antiviral and antimicrobial activities of nanoparticles are also well evident. The ratio of nanoparticles surface area to their volume is high and that allows them to be an advantageous vehicle of drugs in many respects. Effective uses of various materials for the synthesis of nanoparticles impart much specificity in them to meet the requirements of specific therapeutic strategies. The potential therapeutic use of nanoparticles and their mechanisms of action against infections from bacteria, fungi and viruses were the focus of this review. Further, their potential advantages, drawbacks, limitations and side effects are also included here. Researchers are characterizing the exposure pathways of nano-medicines that may cause serious toxicity to the subjects or the environment. Indeed, societal ethical issues in using nano-medicines pose a serious question to scientists beyond anything.

Paying with information
Authors: Kaya Ayça
Published: May 2023

The founder of a start‐up (principal) who has a project with uncertain returns must retain and incentivize an agent using promise of future payments and information gathering. The agent's effort incrementally advances production and such advance is a prerequisite for gathering new information. The principal decides how much information to gather based on these incremental advancements. The principal faces cash constraints. The agent's outside option is large relative to his effort cost. Equilibrium features one of two outcomes:immediate learning, whereby the agent's compensation is low, learning is immediate and retention is possible only conditional on the project being of high quality; orgradual learning, whereby the agent's compensation is high, learning is gradual, the agent never quits and effort is inefficiently high.
On rank dominance of tie‐breaking rules
Authors: Allman Maxwell , Ashlagi Itai , Nikzad Afshin
Published: May 2023

Lotteries are a common way to resolve ties in assignment mechanisms that ration resources. We consider a model with a continuum of agents and a finite set of resources with heterogeneous qualities, where the agents' preferences are generated from a multinomial‐logit (MNL) model based on the resource qualities. We show that all agents prefer a common lottery to independent lotteries at each resource if every resource is
popular, meaning that the mass of agents ranking that resource as their first choice exceeds its capacity. We then prove a stronger result where the assumption that every resource is popular is not required and agents' preferences are drawn from a (more general) nested MNL model. By appropriately adapting the notion of popularity to resource types, we show that a hybrid tie‐breaking rule in which the objects in each popular type share a common lottery dominates independent lotteries at each resource.

Published: May 2023

The objective of this study was to monitor the reclamation development and assess the LULC changes in a reclaimed area in Upper Egypt. GIS and remote sensing-based multi-temporal Landsat imageries (i.e., Landsat-5 and Landsat-8; 30m) were utilized for mapping and analyzing the spatiotemporal dynamics between 2005 to 2020. Both supervised-based maximum likelihood classifier (MLC) and normalized difference vegetation index (NDVI)-based thresholds were implemented. The results of both methods were cross-compared and showed that the agriculture activities started in 2004 with small and sparse agriculture patches. The bare land occupied more than 65.1% of the total area between 2005-2008. Overall, using the MLC and NDVI-based classification, the authors observed an increase of approximately 455.6% (17,027.7 ha) and 477.2% (16,973.5 ha) over 15 years (2005-2020), respectively. The results could be very useful for assessing the success of the Egyptian strategies to sustain the agricultural land areas and food production through horizontal expansion and investment in the desert areas.

Prediction of Ultimate Bearing Capacity of Oil and Gas Wellbore Based on Multi-Modal Data Analysis in the Context of Machine Learning
Authors: Li Qiang
Published: May 2023

As important research for drilling engineering, the prediction of oil and gas shaft lining conditions is changing from the traditional method based on the mechanism model to the intelligent prediction method combining the mechanism model with the data model. Therefore, this paper establishes a stacking integrated model for predicting the uniaxial compression strength (UCS) of rock based on four basic parameters that can reflect the characteristics of rock mass. At the same time, the expectation-maximation (EM) algorithm is used to optimize the hidden Markov models (HMM), and a fuzzy random model of the ultimate bearing capacity of oil and gas shaft lining is established. The uncertain distribution of main parameters of rock mass is analyzed, and the corresponding fuzzy random distribution law is obtained. The experimental results show that the stacking integration algorithm is of great help to improve the prediction effect of rock mass compressive strength. The EM-HMM model has the advantages of small error, high efficiency, and fast convergence after two fuzzy random processes. Using this algorithm is helpful to analyze the stress state and parameter response mechanism of the shaft lining, dynamically generate optimized parameters, and provide technical support for reducing the incidence of complex drilling accidents, shortening the well construction period and lowering the drilling cost.

Published: May 2023

3D printing is now being used in many different applications. This adoption of 3D printing in these applications is accelerated by the development of new materials such as high performance polymers and nanocomposites. In this study, a commercially-available stereolithographic (SLA) resin has been reinforced with 0%, 0.1%, 0.3% and 0.5% nanosilica powder. The resulting mixture has been 3D-printed using a stereolithography 3d printer. The 3D-printed composites have been post-cured in a UV chamber and the mechanical properties have been assessed under compressive loading using a universal testing machine (ASTM-D695). The results show that adding nanosilica powder to the resin would increase the compressive strength of the resin, and that the highest compressive strength could be observed when 0.1% nanosilica poweder was added to the resin.

Authors: Sosiati Harini , Ma'arif M. Guntur , Firmansyah Wijaya Agus , Hamdan Sinin
Published: May 2023

This study aims to fabricate and characterize the hybrid composites of duck eggshell (DE) and abaca fiber reinforced epoxy. The composites were fabricated with 20 vol.% fillers consisting of DE/abaca fiber with ratios of 0/20, 5/15, 10/10, and 20/0. We then characterized their mechanical (tensile and flexural) and water absorption properties. At the same time, the characteristics of eggshell particles were examined by SEM/EDS and XRD. We observed that the DE contains higher CaCO3 than chicken eggshells, making it appropriate to be chosen as a filler. The alkali-treated (AT) abaca improves the flexural and tensile strengths of abaca/epoxy composite but slightly decreases those of DE/AT abaca/epoxy composites. The composite with a 5/15 DE/AT abaca fiber ratio shows the maximum flexural strength. However, the flexural strength of the composites made of the epoxy matrix is almost the same as that of polyester and is 21% lower than that of PMMA. The use of polyester and PMMA matrixes significantly reduces the water absorption rate to around 3.50%.

According to the results, sound brazing joint was attained, presenting an average tensile strength and ductility of about 230 MPa and 20 %, respectively.
Sentiment Gradient - Improving Sentiment Analysis with Entropy Increase
Authors: Cardoso Durier da Silva Fernando , Bicharra Garcia Ana Cristina , Wolfgand Matsui Siqueira Sean
Published: May 2023

Information sharing on the Web has also led to the rise and spread of fake news. Considering that fake information is generally written to trigger stronger feelings from the readers than simple facts, sentiment analysis has been widely used to detect fake news. Nevertheless, sarcasm, irony, and even jokes use similarwritten styles, making the distinction between fake and fact harder to catch automatically. We propose a new fake news Classifier that considers a set of language attributes and the gradient of sentiments contained in a message. Sentiment analysis approaches are based on labelling news with a unique value that shrinks the entire message to a single feeling. We take a broader view of a message’s sentiment representation, trying to unravel the gradient of sentiments a message may bring. We tested our approach using two datasets containing texts written in Portuguese: a public one and another we created with more up-to-date news scrapped from the Internet. Although we believe our approach is general, we tested for the Portuguese language. Our results show that the sentiment gradient positively impacts the fake news classification performance with statistical significance. The F-Measure reached 94 %, with our approach surpassing available ones (with a p-value less than 0.05 for our results).

Published: May 2023

Metabolites from clove (Syzygium aromaticum L.) have been extensively studied for various pharmacological uses, including quercetin. Endophytic bacteria isolated from plant tissues can produce similar secondary metabolites as their host plants. However, little is known about the antioxidant activity of the endophytic bacterial extract from clove leaves. Amongst the potential bacterial groups, the genera of Bacillus have been widely studied as a source of antioxidants. Thus, this study, we examined the potential antioxidant properties of Bacillus sp., isolated from clove leaves. We have successfully isolated ten endophytic bacteria, of which only one isolate (P1U2) was found non-pathogenic based on a hemolytic assay. Based on the 16S rRNA sequence, P1U2 shared the highest similarity to Fictibacillus phosphorivorans. The extract of extracellular metabolites of P1U2 contains quercetin compounds, based on LC-MS analysis. The results of the antioxidant activity test using the DPPH assay showed that the P1U2 extract had an IC50 value of 161 mg/ml. The supplementation of the extract on culture media reduced the ability of S. cerevisiae to decolorize mutagen malachite green and increased cell viability. Furthermore, the addition of 161 ppm extract was able to counteract UV mutagens effects of UV exposure and toxicity of malachite green, significantly increasing the growth of S. cerevisiae. Suggesting the bioactivity of the extract in combating mutagens. To the best of our knowledge, this is the first study to report a quercetin-rich extract derived from endophytic bacteria, F. phosphorivorans. Thus, further study is required to optimize the synthesis of quercetin from isolate P1U2.

Uma agremiação a serviço do bairro: O Vila Isabel Futebol Clube (1910-1941)
Authors: Rodrigues da Silva Bruno Adriano , De Melo Victor Andrade
Published: May 2023

Em 1910, foi fundado o Vila Isabel Futebol Clube. Nosso intuito é, ao discutir a trajetória dessa agremiação, dedicar atenção a sua participação no delineamento de um perfil para o bairro no qual se encontrava, perceber como suas ações se imbricavam com o entorno de sua sede. A opção por investigar essa associação esportiva deveu-se a sua conformação societária. Seus membros eram oriundos de estratos médio e alto que viviam em Vila Isabel ou nas redondezas, não pertencendo, todavia, aos mais elevados escalões socioeconômicos que moravam nos bairros mais valorizados do Rio de Janeiro. O clube era uma expressão de uma “elite intermediária” da cidade. Além disso, teve que lidar com a heterogeneidade social da região onde se localizava. “Pequeno, mas de grandes iniciativas”: assim se referiu ao Vila Isabel um cronista por ocasião de seu décimo aniversário. Consideramos que essas características nos permitem perceber algo dos movimentos societários da cidade, bem como sua inserção nos registros espaciais.
Na rua se faz trabalho: música e religiosidade entre rastafaris na periferia paulistana
Authors: Yokoi Marcelo
Published: May 2023

A música se tornou uma das maiores formas de expressão do Rastafari, movimentação cultural que surgiu em 1930 na Jamaica e que durante o seu desenvolvimento estabeleceu conexões entre religiosidade, política, lazer e trabalho. Apesar de sua transnacionalização estar associada à difusão de um veículo da cultura popular, a música reggae, é no nyahbinghi que reside a principal fonte espiritual e musical, sendo ele um serviço (cerimônia ou trabalho espiritual) onde são entoados chants (hinos) ao toque de três tambores principais. Neste artigo serão abordados aspectos da organização de um grupo formado por rastafaris, o Instituto Cultural Bola de Fogo, apresentando reflexões sobre a prática do nyahbinghi a partir do trabalho de campo realizado nas apresentações-rituais que acontecem na cidade. Para uma melhor contextualização, inicialmente trarei algumas considerações históricas sobre o rastafari e sua musicalidade, o que remente a uma política contra o colonialismo e a colonialidade. Passado e presente confluem, bem como o material e o espiritual, trazendo conhecimento ancestral e benesses curativas. Inserido em programações de lazer periférico, percebe-se a importância da política e da religião emergindo nas ruas e espaços públicos na cidade.

Published: May 2023

Introduction: Aging is a dynamic process in which biochemical and physiological changes are related to a higher frequency of pathological processes, which ultimately lead the human being to death. Part of these alterations and pathologies are improved using medicines, so older adults are great consumers of medicines. Several instruments have been used to evaluate the use of inappropriate medications in older adults, with Beers Criteria frequently used. The concept of medication adherence has undergone changes over time and represents the degree to which the patient’s behaviour corresponds and agrees with the recommendations of a doctor or other health professional. Medication non-adherence to entails a decrease in the quality of life of the patients and high costs for the health systems. Objectives: To characterize drug therapy in older adult users of a northern Portuguese community pharmacy, as well as to identify the presence of potentially inappropriate medications (PIMs) in the older adult and to assess medication adherence. Methods: Exploratory and descriptive study. The target population was older adult users of a community pharmacy in the municipality of Valpaços, Portugal. The data collection instrument used was a questionnaire applied in the form of a structured interview. The potentially inappropriate medications (PIMs) identification was based on the most recent version of the Beers Criteria published in 2019. The MAT (Measurement of Adherence to Treatments) scale was used to evaluate medication adherence. The statistical treatment included the calculation of absolute and relative frequencies, measures of central tendency and dispersion. Results: 60 older adult people were interviewed, 53.3% of them women. The average age was 78.35 years. Among these, 55.0% were married/had a non-marital partner, 71.7% lived accompanied, 26.7% had primary school education, 40.0% received less than 300 Euros monthly and 95.0% lived in the municipality of Valpaços. Each older adult person consumes on average 6 different types of medication per day. Major polymerization was present in 66.7% of older adults, and 94.2% of the drugs being prescribed by the physician. In 34.7% of the cases, the medication had been used for at least 1 year and only 3.4% reported feeling adverse reactions. Of the total 326 drugs identified, the most prescribed pharmacotherapeutic groups were drugs acting in the cardiovascular system 27.2% and in the digestive system 24.2%. Additionally, 15 drugs classified as potentially inappropriate medication were identified in the older adult. Most of the older adults (76.7%) did not adhere to drug therapy, these being mainly females with primary education, living with a partner and less than 300 euros/month. Conclusion: Polymedication and the use of potentially inappropriate medications are common in older adults. Medication adherence is low.

Com o envelhecimento, a população idosa pode tornar-se mais frágil e está propícia à ocorrência de alguns eventos indesejados, como é o caso das quedas, sendo estas consideradas um problema de saúde pública. A prevenção das quedas em idosos é um desafio para os enfermeiros. Um dos aspetos mais relevantes para a prevenção é a deteção precoce de fatores de risco, onde se destacam as alterações do equilíbrio. Foi feito um estudo quantitativo, descritivo e transversal, tendo como objetivo avaliar o risco de quedas na pessoa idosa que reside no domicílio. A população-alvo são idosos a residir no domicílio, estudando-se uma amostra de 77 indivíduos com idades compreendidas entre os 65 e os 94 anos, (x̅ = 81,32 ± 7,76 anos), sendo 58,4% do sexo feminino. A recolha de dados foi obtida através da realização de entrevistas estruturadas e com utilização do Teste de Tinetti. A maioria dos idosos (72,7%) reside acompanhado. Quanto ao equilíbrio estático, constatou-se que os idosos apresentam maiores dificuldades quando se encontram na mesma posição com apoio unipodal (42,9%), ou aquando da realização de uma volta de 360º (44,2%). No equilíbrio dinâmico, a maioria manteve o equilíbrio aquando da avaliação dos vários itens. Verificou-se que 18,2% da amostra apresenta elevado risco de quedas. O estudo permitiu identificar as situações onde o grupo de idosos em estudo apresenta um maior desequilíbrio, bem como avaliar o risco de quedas.
