Friction and wear between sliding surfaces can lead to various issues in industrial applications, such as increased costs, reduced machine lifespan, loss of functionality, energy loss, and decreased system efficiency. To mitigate these problems, lubricants and coatings are commonly employed. This study aims to investigate the impact of coatings and lubrication on friction coefficient, wear volume loss, and lubricant temperature using the block-on-ring wear test. The effectiveness of different coatings (uncoated, DLC, CrN, and TiALN) and lubricants (anti-friction graphene oxide additive oil and strong nano engine oil additive) in reducing friction and wear is evaluated. The block-on-ring tests are conducted under varying loads (6-60 N), speeds (1450 rpm), lubricant volumes (40 ml), and durations (2-20 min). The coefficient of friction is measured using an inline load cell, wear volume loss is determined by weighing the blocks before and after the experiment, and lubricant temperature is monitored using thermocouples. The results indicate that the coefficient of friction decreases with increasing load, while the lubricant temperature rises. Coated blocks exhibit lower wear volume loss compared to uncoated blocks. Overall, the combination of CrN-coated blocks and anti-friction graphene oxide additive oil demonstrates the best tribological performance.

Polylactic acid (PLA), a biodegradable and biocompatible thermoplastic commonly utilized in 3D Printing filaments, undergoes changes in properties upon recycling. The objective was to elucidate the role of extrusion temperature and screw speed in modulating the quality of recycled PLA filament, as well as in controlling its dimensional attributes. Recycled PLA pellets (3D850D) were extruded using a single filament extruder machine within an extrusion temperature range of 145°C to 165°C and a screw speed varying from 2 rpm to 6 rpm. The extruded filaments were subsequently 3D printed into specimens adopting a 0° raster angle, line infill pattern, and a 100 percent infill density, then tested as per ASTM D638 mechanical standards. The study revealed a profound influence of extrusion parameters on the filament's ultimate tensile strength, yield strength, and diameter. Optimal extrusion conditions - 155°C and 5 rpm - resulted in maximum mechanical strengths, while the parameters yielding filament diameters closest to commercial standards were identified as 5 rpm and 155°C. These results under-score the possibility of optimizing the recycled PLA filament's properties through adept control of extrusion parameters. Consequently, this investigation supports the potential use of recycled PLA filament in the 3D printing industry as a sustainable and performance-efficient material, offering a tangible step towards environmentally friendly additive manufacturing practices.

Published: November 2023

The data-driven Battery Management System (BMS) plays a crucial role in Electric Vehicles (EVs) and Battery Energy Storage Systems (BESS). EVs and energy storage systems utilize Lithium-ion (Li-ion) batteries due to their high energy density. However, recent concerns have arisen regarding the efficiency and reliability of Li-ion batteries, mainly due to issues of overheating and aging. Consequently, accurately predicting the State of Charge (SOC), State of Health (SOH), and degree of aging of the battery has become immensely important. This research focuses on analysing the accelerated loading effects on Li-ion batteries under various load conditions to gain insights into their performance under extreme mechanical stress. This paper also proposes a model employing a Feed-Forward Neural Network (FNN) to investigate the effects of fast-loading variations. The reliability testing of batteries involves monitoring their degree of aging through repeated charging or discharging cycles, facilitated by an IoT-based remote monitoring system. Experimental data was collected using the Neware BTS4000, a standard battery test equipment, and then validated with the FNN model, achieving a maximum accuracy of 99.9%.

ABSTRACT:

Introduction:

Covid-19 emerged as pandemic. In the beginning, due to the rapid spread of virus it was difficult to understand fully its pathogenesis but various inflammatory markers were found to be raised. Along with the detection of virus by polymerase reaction (PCR), studies of these markers not only help in diagnosis but also in assessing the prognosis of covid-19 infection.

Material and methods:

This cross sectional study was conducted in the Capital Hospital, CDA Islamabad from December to June 2022. After taking consent various inflammatory markers were recorded on a proforma. Patients were followed and outcome was also recorded. The data collected was analyzed by percentage/ frequency distribution. T-test was applied and p-values were calculated (significant p-value=<0.05).  Sensitivity, specificity, positive and negative predictive values, area under curve (AUC) and accuracy were calculated by using SPSS, version 23.

Results:

A total of 185 covid-19 PCR positive patients were included in the study. 112(60.5%) were men and 73 (39.5%) were women. 165(89.2%) patients were > 40 years of age. 117 (63.2%) patients had mild /moderate disease and 68(36.8%) had severe disease.  162 (87.5%) patients were discharged and 23 (23.4%) expired. AUC in relation to severity of disease was 0.603 for C- reactive protein (CRP), 0.543 for lactate dehydrogenase (LDH), 0.525 for D. dimers and 0.619 for ferritin. Accuracy in relation to disease severity was as following: CRP 57.4%, D. dimers 52.4 %, ferritin 57.9% and LDH 55.7%.  AUC in relation to outcome of covid-19 was 0.699 for CRP, 0.668 for LDH, 0.742 for D. dimers and 0.677 for ferritin. Accuracy of inflammatory markers in relation to outcome was as following: CRP 45.9%, D. dimers 61.2%, LDH 48.1% and ferritin 46.9%.

Conclusion:

Serum ferritin showed the highest accuracy (57.9%) in assessing the covid-19 severity and D. dimer came up with highest accuracy (61.2%) in assessing disease outcome.

INTRODUCTION:
Distal radius fractures are one of the commonest fractures experienced by the Orthopaedic surgeons. Pain on the ulnar aspect of the wrist is the most usual complication of such fractures.  Corticosteroid injection is a simple and effective method for elevating pain of such nature. 
OBJECTIVE: To compare the mean pain score with prophylactic corticosteroid injection versus placebo in management of wrist pain on ulnar aspect in patients presenting with fracture of distal radius.
MATERIAL AND METHODS:
Study Design: Randomized controlled trial
Setting: Orthopedic Surgery Department, Benazir Bhutto Hospital, Rawalpindi
Duration: Six months (March 5, 2018 to Sept 5, 2018)
Data Collection Procedure:
80 patients were included by using non-probability consecutive sampling after fulfilling the selection criteria. Demographic profile (patient name, age, gender, anatomical side and contact details) was obtained. Patients were splitted in two random groups by simple lottery method. Patients of group A were given one shot of 80mg corticosteroid in the area of ulnar styloid process near TFCC and group B patients were given a shot of distilled water (2 cc). Both group of patients were followed in OPD for 3 months in their postoperative visits. Visual analogue scale (VAS) score was recorded. Data was analyzed using SPSS version 21.
Results:
The mean age of the patients was 41.05 ± 11.05 years and age range of 40 years. The mean age in the corticosteroid and placebo groups was 39.68±10.67 years and 42.42 ± 11.39 years respectively. There were 42 (52.50%) male and 38 (47.50%) female patients with a higher male ratio i.e., 1.10:1. In corticosteroid and placebo groups there were 21 (52.50%) male and 19 (47.50%) female cases. The mean pain at baseline was 7.72 ± 1.66 while in the corticosteroid and placebo group, the mean pain was 7.60 ± 1.67 and 7.85 ± 1.65 respectively with statistically equal mean pain p-value = 0.504. After 3 months of treatment, mean pain in the corticosteroid group was 1.30 ± 0.66 and was 2.60 ± 1.58 in the placebo group, p-value < 0.001.
Conclusion:
Our findings suggested that prophylactic corticosteroid injection is more effective in reducing pain in patients with distal radial fracture than placebo. By using prophylactic corticosteroid injections in the future, we can reduce pain to achieve more satisfaction of patients.

Authors: Ngoc Ly Dang
Published: November 2023

Diatoms are one of the microalgae species commonly used as food for many aquatic organisms during the hatchery stage. The culture of diatoms usually uses silicon from Na2SiO3, but this salt compound easily causes the precipitation of trace ions in the culture medium. This study is to fabricate SiO2 material particles used to replace Na2SiO3 in the period of diatom proliferation and application in aquiculture. The material particles were synthesized based on the Stober method using the surfactant compound CTAB with a spherical particle structure with the particle size of about 700 nm. Testing using SiO2 material particles showed faster growth of diatoms compared with conventional culture media using Na2SiO3.

The Gas Accretion Rate of Galaxies over z ≈ 0–1.3
Authors: Chowdhury Aditya , Kanekar Nissim , Chengalur Jayaram N.
Published: November 2023

We present here estimates of the average rates of accretion of neutral gas onto main-sequence galaxies and the conversion of atomic gas to molecular gas in these galaxies at two key epochs in galaxy evolution: (i) z ≈ 1.3–1.0, toward the end of the epoch of peak star formation activity in the Universe, and (ii) z ≈ 1–0, when the star formation activity declines by an order of magnitude. We determine the net gas accretion rate R
Acc and the molecular gas formation rate R
Mol by combining the relations between the stellar mass and the atomic gas mass, the molecular gas mass, and the star formation rate (SFR) at three epochs, z = 1.3, z = 1.0, and z = 0, with the assumption that galaxies evolve continuously on the star-forming main sequence. We find that, for all galaxies, R
Acc is far lower than the average SFR R
SFR at z ≈ 1.3–1.0; however, R
Mol is similar to R
SFR during this interval. Conversely, both R
Mol and R
Acc are significantly lower than R
SFR over the later interval, z ≈ 1–0. We find that massive main-sequence galaxies had already acquired most of their present-day baryonic mass by z ≈ 1.3. At z ≈ 1.3–1.0, the rapid conversion of the existing atomic gas to molecular gas was sufficient to maintain a high average SFR, despite the low net gas accretion rate. However, at later times, the combination of the lower net gas accretion rate and the lower molecular gas formation rate leads to a decline in the fuel available for star formation and results in the observed decrease in the SFR density of the Universe over the last 8 Gyr.
RNO 54: A Previously Unappreciated FU Ori Star

Published: November 2023

We present evidence in support of the hypothesis that the young stellar object RNO 54 is a mature-stage FU Ori type source. The star was first cataloged as a “red nebulous object” in the 1980s but appears to have undergone its outburst prior to the 1890s. Present-day optical and near-infrared spectra are consistent with those of other FU Ori-type stars, both in the details of spectral line presence and shape, and in the overall change in spectral type from an FGK-type in the optical, to the M-type presented in the near-infrared. In addition, the spectral energy distribution of RNO 54 is well-fit by a pure-accretion disk model with parameters:

Neuf ans après la départementalisation de Mayotte, l’action publique s’y institutionnalise et se normalise, notamment dans le champ des politiques sociales, restées longtemps facultatives du fait de l’histoire coloniale. Les principes majeurs de division et de hiérarchies issus de cette histoire – la race, le genre et la nationalité – n’ont pas disparu : ils se sont amplement recomposés au gré des évolutions historiques de grande ampleur que cet ensemble régional a connues. Par les nouvelles règles qu’elle impose dans tous les domaines et par les ressources qu’elle alloue, l’action publique joue un rôle considérable dans ce mouvement. En se centrant sur le secteur du travail social, cet article aborde les logiques de racialisation qui traversent l’action publique locale en contrastant les parcours et les points de vue de professionnel·les du travail social – éducateur/rices, médiateur/rices, chef·fes d’équipes et dirigeants associatifs –, que ces personnes soient en situations majoritaire ou minoritaires. Comment ces logiques de racialisation sont-elles reconduites, vécues, appropriées, parfois contestées par des professionnel·les aux positions contrastées, sinon antagonistes ?
Association of meeting 24-hour movement guidelines with low back pain among adults
Authors: Kastelic Kaja , Šarabon Nejc , Burnard Michael D. , Lipovac Dean , Pedišić Željko
Published: November 2023

Background

According to recently published 24-hour movement guidelines, adults should spend: ≥150 minutes/week in moderate-to-vigorous physical activity (MVPA); <8 hours/day in sedentary behaviour (SB); and 7–9 hours/day sleeping.

Objective

We explored the association between meeting these recommendations and low back pain (LBP)—the most common musculoskeletal disorder.

Methods

We collected self-reported data from 2333 adults about: MVPA, SB and sleep duration; frequency and intensity of LBP; and sociodemographic and lifestyle characteristics.

Results

Meeting a combination of SB and sleep recommendations was associated with lower odds of LBP in the past week and past month (adjusted odds ratio [OR]: 0.64 and 0.52, respectively; p < 0.05 for both). Among LBP sufferers, meeting any combination of recommendations that includes sleep was associated with lower odds of frequent (OR range: 0.49–0.61; p < 0.05 for all) and intense (OR range: 0.39–0.66; p < 0.05 for all) LBP in the past week, while meeting a combination of SB and sleep recommendations or all three recommendations was associated with lower odds of intense LBP in the past month and past year (OR range: 0.50–0.68; p < 0.05 for all). The likelihood of experiencing higher frequency and intensity of LBP decreased with the number of recommendations met (p for linear trend < 0.05).

Conclusion

Meeting the SB and sleep recommendations in combination is associated with a lower likelihood of LBP, while adhering to the overall 24-hour movement guidelines or any combination of recommendations that includes sleep is associated with lower frequency and intensity of LBP among LBP sufferers.
Chirped LG modes interference formed chiral beams

Published: November 2023

Non-Gaussian spatial intensity distribution beams used in laser micro- and nano-machining find many applications. For instance, Bessel beams, having a small diameter and a very long focal zone, allow the fabrication of high aspect ratio modifications in transparent materials. Higher-order Laguerre–Gauss modes are used in particle manipulation and even for multiplexing in optical communication. The temporal intensity distribution of a pulse is mostly overlooked or fixed to Gaussian shape distribution. However, pulse-shaped beams could improve the same fields of particle manipulation as optical traps, or the laser manufacturing. In this paper, we demonstrate a method of constructing a helical spatiotemporal intensity distribution beam the rotation of which in time can be varied. We demonstrate the analytical and numerical results and show an experimental realization of such a structure.
Sum-frequency generation and amplification processes in semiconductor superlattices
Authors: Čižas Vladislovas , Alexeeva Natalia , Alekseev Kirill , Valušis Gintaras
Published: November 2023

Semiconductor superlattices are very well-known structures due to their specific electron transport properties, making them extremely attractive to be employed in electronic or optoelectronic devices. The interest in such structures has been recently additionally stirred up due to the first successful experimental demonstration of parametric gain in GaAs/AlGaAs superlattices, resulting in the generation of harmonics, half-harmonics and fractional harmonics. This invention paves the way for a successful realization of superlattice-based generators and amplifiers up to the terahertz frequency range. Despite the emerging experimental results and decade-long theoretical research, unresolved aspects, related to the physical processes inside the superlattices, persist. Lately, the biasing effect was extensively analysed for the case of degenerate processes in the superlattice; however, the non-degenerate case was left out of frame until now. Within this research, we further expand the boundaries of previous investigation by exploring the differences of non-degenerate processes. The study uncovers the asymmetry appearance of the probe field vs. relative phase dependences as well as the possibility of parametric fractional frequency generation. Finally, the concept of energy reflow between two participating probes is predicted and discussed.

Learning that challenges preconceived notions and inspires the development of fresh perspectives on the world has been referred to as transformative learning. This study offers a thorough analysis of how changes in learning have been reflected, including how they have an impact on curricula, in order to guide the master of health professions education’s potential field applications. Through purposive sampling, 15 students of MHPE from Islamic International Medical College, Rawalpindi, Pakistan have been chosen. The study design is phenomenological in nature. A semi-structured interview has been used. All the interviews were audio-recorded and separately transcribed. The transcribed interviews were then imported into NVivo software version 11 for analysis. A thematic analysis has been done and six themes are generated. The applications of distance learning positively related to teaching and learning practices and students identified a change in their attitudes toward distance learning. Major factors recognized were student-centered learning, small group discussions, peer-assisted learning, technology awareness, personal grooming, and motivation. About three-fourths of the sample population experienced a transformation in their distance learning after going through a Master’s in Health Professionals Education. The impact of hands-on activities and small group discussions turned out to be the strongest factors that caused the transformation in distance learning.

Authors: Shetty Sharan Kumar , Spulbar Cristi , Ramona Birău
Published: November 2023

Health insurance is one of the most essential techniques that can assist in the utilization of health coverage and provide protection to the life of policy holders. However, in Karnataka, youth's attitudes regarding health insurance are quite different from those in other cities. Karnataka residents have not invested in health insurance despite the fact that the city is growing. Nearly 10–30% of young people have health-harming behaviours or conditions that demand the immediate attention of decision-makers and public health specialists. This population is specifically affected by, and is negatively impacted by, nutritional disorders (both malnutrition and overnutrition), tobacco use, harmful alcohol use, other substance use, high-risk sexual behaviours, stress, common mental disorders, and injuries like road traffic injuries, suicides, and violence of various types. The chapter promotes health insurance awareness among youth in Karnataka and knowing the effect of the COVID-19 pandemic on perceived attitudes toward health insurance in the minds of youth as well.

Published: November 2023

At least 200 million people were affected by the corona virus (COVID-19) disease during the pandemic, and over 5 million deaths occurred by October 2021. In 2021, the International Diabetes Federation (IDF) reported that 537 million people worldwide were living with diabetes, and it caused 6.7 million deaths. Long-term COVID-19 patients endure a broad variety of physical and mental problems. People with long-term COVID-19 generally report low living quality, poor mental health, and unemployment on top of their suffering and problems. These patients may need long-term symptoms monitoring, social assistance, physical rehabilitation, and management of diabetes complications. Future health issues related to long COVID-19 and diabetes will need resilient healthcare systems to enable fast and effective solutions.

The United States is facing a growing crisis in the form of increasing medical care costs for both the insured and uninsured. One innovative strategy to address increasing costs is the use of medical tourism. Medical tourism is defined by the OECD as “the practice of travelling to another country to obtain medical treatment.” It has become an increasingly popular option as it offers patients the ability to access treatment outside of their home country, often at a lower cost. This chapter will provide a brief overview of medical tourism, its current and potential applications, and potential challenges and benefits associated with it as an innovative approach to address the healthcare crisis of high medical costs in some specific areas of treatment.

Water is unambiguously susceptible to contamination, as it is able to dissolve a broader spectrum of substances than any other liquid on Earth. Increasing population and urbanization have been imposed to monitor water quality and wastewater management in the current global scenario. Conventional water quality monitoring involves water sampling, testing, and investigation, which are usually performed manually and are not dependable. Rapid economic prosperity generates a larger quantity of wastewater enriched with a broad range of pollutants that pose serious threats to the environment and human health. Advancements in artificial intelligence and machine learning approaches have shown breakthrough potential toward large dataset capture and analysis of large datasets to attain complex large-scale water quality monitoring and wastewater management systems. The current chapter summarizes prospects and potentials of AI technologies for the amelioration of water quality monitoring and wastewater management to establish an integrated sustainable biocomputation platform in the near future.

Sabe-se que a fase de puberdade é uma fase de grandes mudanças físicas e psíquicas, que por muitas vezes ocorrem de forma brusca e veloz, tais alterações físicas influenciam de forma direta e indireta as atividades cotidianas do adolescente, e em casos de alterações como dores e disfunções musculoesqueléticas posturais, podem ser fatores determinantes para deformidades, contraturas e danos psíquicos. A pesquisa tem por objetivo de avaliar quantitativamente a interação que o ambiente escolar possui, nas alterações posturais, dor e mobilidade, presentes nos adolescentes em fase de estirão puberal. Trata-se de uma pesquisa exploratória, realizada em um colégio da cidade de Mandaguari PR, em que foram utilizados instrumentos avaliativos como, índice de avaliação postural, escala visual analógica de dor, testes de goniometria para verificar a mobilidade de coluna, e de Adams para confirmar a presença de escoliose. Os resultados obtidos mostram um índice alto de alterações como, mobilidade, dores, e disfunções musculoesqueléticas, sendo as alterações de mobilidade de maior prevalência, seguido de alterações posturais estáticas, dor, e indicativos de escoliose leve. A partir dos resultados obtidos, quantifica-se a variabilidade das alterações encontradas de forma precisa, em que tais alterações podem ser observadas de forma precoce, receber intervenções fisioterapêuticas preventivas, assim trazendo qualidade de vida, autoestima e conforto ao estudante escolar.

Durante a gestação a bexiga tende a se deslocar e ser pressionada pelo útero gravídico, aumentando a pressão abdominal e diminuindo a capacidade vesical, predispondo à incontinência urinária. Portanto, objetivou-se verificar a prevalência de incontinência urinária e o impacto na qualidade de vida em gestantes. Trata-se de uma pesquisa quali-quantitativa, realizada com 21 gestantes, por meio da aplicação de três questionários. Os resultados indicaram uma maior prevalência de incontinência urinária em gestantes multíparas. Através desta pesquisa, pode-se identificar uma maior prevalência de incontinência urinária em multíparas e em gestantes com idade mais avançada. Com relação a qualidade de vida, não houve impacto significativo na maioria dos domínios analisados.

A reabilitação motora é extremamente importante para as pessoas que apresentam alguma disfunção neurológica ou ortopédica que afetam a sua funcionalidade, portanto a avaliação fisioterapêutica é um ponto crucial no tratamento hidroterapêutico. O objetivo desse estudo é realizar uma caracterização do perfil motor dos pacientes tratados através da hidroterapia. Dados como perfil motor, diagnóstico clínico e fisioterapêutico, bem como o comportamento de flutuação dos pacientes foram coletados para correlações. O maior número de entrevistados é do sexo feminino e os que tinham encurtamento muscular apresentaram aumento da dor. A capacidade de flutuação foi relacionada com a escala de dor e a idade dos entrevistados, e evidenciaram que quanto maior a idade, maior é a dificuldade de flutuação.

Dentre os transtornos neuromotores que afetam o SNC, a hipertonia elástica (espasticidade) é uma alteração comum, podendo gerar problemas anatômicos incluindo luxações. O objetivo deste estudo foi analisar a prevalência da luxação de quadril nas consultas médicas realizadas na Associação Norte Paranaense de Reabilitação (ANPR) no período de 14 meses, juntamente com dados sócio demográficos e dados clínicos.  Foram analisados 161 relatórios médicos no arquivo da ANPR para investigação de luxação, no qual foram solicitados a radiografia (Raio X) de quadril para 54 indivíduos, retornaram para análise 43 radiografias onde se apresentaram 12 pacientes com luxação de quadril, uma prevalência de 22%. Relacionando com os dados clínicos desses pacientes demonstra-se que a maior parte das luxações de quadril ocorreram em portadores de transtornos neuromotores com presença de espasticidade.

Influência da sobrecarga do conselho de administração no valor de mercado e desempenho de empresas brasileiras de capital aberto
Authors: Teixeira Pereira Michel , Edwards Barros Claudio Marcelo
Published: November 2023

Objetivo: O presente trabalho objetivou examinar a influência da sobrecarga dos conselhos de administração na valoração e no desempenho das empresas brasileiras de capital de aberto.Método: Este estudo identificou, na forma censo, a existência de sobrecarga nos CAs, além de descrever a performance de variáveis ligadas a relativização do valor de mercado das corporações ao valor contábil. Para análise de dados foi utilizado dados em painel. Os modelos econométricos utilizados compõem as variáveis de performance como endógenas e a medida de sobrecarga como exógena.Originalidade/Relevância: Essa pesquisa é relevante porque tem como objetivo aprofundar a escassa literatura no Brasil sobre Busy Board. Além disso, a condução do estudo abrange um olhar alternativo mediante o desenvolvimento de métrica alternativa para identificação e mensuração de Boards envolvidos em sobrecarga. E, finalmente, trata-se de uma pesquisa proveitosa porque deverá auxiliar órgãos reguladores e comunidade dedicada ao estudo de Contabilidade Financeira e Finanças na compreensão de padrões relacionados ao comportamento dos Boards conectados.Resultados: Os resultados apresentam indícios significativos de que, no cenário brasileiro, a Hipótese de Reputação se destaca em detrimento da Hipótese de Sobrecarga. Assim, o estudo traz indicativos de que quanto maior a sobrecarga dos membros do Conselho de Administração, melhor será o desempenho operacional e, consequentemente, o valor de mercado das empresas.Contribuições teóricas/metodológicas/práticas: Diante dos resultados expostos as empresas poderiam divulgar a sobrecarga dos seus membros e do Conselho de Administração contribuindo para o processo decisório de investidores individuais e institucionais, diminuindo o nível de assimetria de informações. Nessa conjuntura, o presente estudo corrobora com o entendimento acerca do número de interligações corporativas dos membros do Conselho de Administração, de modo que saber se a existência de interligação corporativa vem a ser prejudicial para o desempenho e valoração da empresa e assim viabilizar externalidades positivas para a economia brasileira.

Published: November 2023

Objetivo: Esse estudo tem como objetivo verificar a relação entre o uso de indicadores de avaliação de desempenho e a remuneração de executivos em Instituições Financeiras de capital aberto.Método: É de caráter descritivo, quantitativo e realizado por meio de análises documentais. A base de dados é composta por 26 empresas brasileiras do setor bancário, listadas na B3, com dados dos anos de 2010 a 2019 com regressão por meio de dados em painel.Originalidade e Relevância: No Brasil, a relevância para a situação econômica das instituições financeiras tem interesse cada vez maior no uso dos indicadores de desempenho para a avaliação de seu desenvolvimento, e dessa forma também acompanhar o comportamento dos funcionários em prol de melhores resultados.Resultados: Os resultados mostram que a remuneração total tende a ser influenciada pelo uso de indicadores de desempenho financeiros e de longo prazo, enquanto a remuneração variável tende a sofrer influência apenas de indicadores de longo prazo, e a proporção da remuneração variável tende a ser influenciada pelo uso do indicador de desempenho organizacional e de curto prazo. Além disso, as instituições financeiras que fazem uso de indicadores de desempenho financeiros e de longo prazo tendem a conceder mais remuneração total aos executivos. O estudo também mostra que apenas os indicadores de avaliação individual e não financeiro não exercem influência na remuneração dos executivos das instituições financeiras pesquisadas, sendo os demais indicadores, organizacionais, financeiros de longo e curto prazo, influentes em pelo menos um tipo de remuneração.Contribuições teóricas/metodológicas/práticas: A contribuição teorica e prática do estudo está relacionado com a alta competitividade do setor, a constante busca por lucros e continuidade no mercado, além de monitoramento dos executivos em relação as constantes e altas metas bancárias.
