Authors: Devi Suci Purnama , Aryani Y Anni
Published: April 2024

This research examines the moderating effect of the Independent Board of Commissioners on the relationship between implementing an enterprise resource planning system (ERP) and earnings management in non-financial companies in the Indonesia Stock Exchange. The earnings management variable is proxied through discretionary accruals, which refer to the calculation of the modified Jones model. This research used panel data from 85 companies from 2017 – 2020 to obtain a sample of 340. Employed the moderated regression analysis, the research finds that ERP implementation significantly influences the decline in earnings management. At the same time, the Independent Board of Commissioners can strengthen the relationship between the implementation of ERP systems and earnings management. This study contributes to expanding literature related to company information systems by providing evidence of the influence of ERP implementation on earnings management and how the Independent Board of Commissioner contributes to the relationship.

Published: April 2024

A new era of banking in Indonesia has arrived with digital transformation in the banking sector. Digital banks are the main choice of young people, especially millennials and Generation Z. How to choose the ideal digital bank? This research tries to answer the question by understanding the role of customer engagement on repurchase intention. The author connects digital bank applications with customer satisfaction and customers will be committed to attaching themselves to the selected digital bank application. The author uses structural equation modeling (SEM) to test the research model with a sample of millennial and Generation Z customers (n = 200). The study results show a significant positive influence of customer satisfaction on customer engagement and repurchase intention of this generation of customers. These findings can provide input for application development and marketing strategies that suit customers, especially millennials and Z generations. Other digital application companies in Indonesia can conclude what the expectations of millennial and Generation Z customers are. To the author's knowledge, there have not been many articles discussing digital banks, the relationship between application use which is an antecedent effect on customer satisfaction, and the effect of customer engagement on repurchase intention in Indonesia.
Construção de uma avaliação de viés formativo:
Authors: Vasconcelos Beatriz Nogueira Marques de , Costa Almeida Luana
Published: April 2024

Este artigo examina a experiência de construção coletiva de uma forma de avaliação alinhada à perspectiva formativa. A análise documental observou projeto político-pedagógico, relatórios de aprendizagem, atas do conselho de classe, registros de acompanhamento do progresso dos(as) estudantes e autoavaliações do coletivo. Destacam-se três principais movimentos adotados pelo coletivo como instrumentos de documentação e avaliação: círculos pedagógicos e processos de autoavaliação; tutoria e espaços dialogados na avaliação da aprendizagem; e conselhos de classe coletivos. Observa-se que a forma como a escola passou a organizar seu trabalho pedagógico alimenta um processo de avaliação de viés formativo – o que potencializa, em retroalimentação, os processos internos à escola.
Palavras-chave: Avaliação formativa. Trabalho coletivo. Escola transformadora.

Published: April 2024

Rapid technological developments in the modern era produce technological products such as Augmented Reality (AR). Currently, AR has been utilized as an information technology that supports the productivity of various fields such as education, medical, military, industry, and entertainment. One of the uses of AR in the entertainment field can be seen in the emergence of AR-based games in the game mechanism. AR-based games have started to emerge since the high public interest in the Pokemon GO game in 2016; until now, games have appeared as a result of the transformation that was originally a video game-based game into an AR-based game such as Angry Bird AR. It is very compelling to learn more about how AR-based games' user experience can affect game immersion as an important aspect of game development. The research method employed was a quantitative method using the game experience questionnaire (GEQ) as a measuring tool to assess the influence of game immersion variables on user experience in the Angry Birds AR: Isle of Pigs game. This study found that game immersion has a positive impact on player user experience, but it is essential to consider flow aspects, especially in building the game world.

ANONIMITAS VISUAL DAN PENEKANAN VERBAL: Tinjauan Semiotika Konten Instagram BNN Cegah Narkoba
Authors: Habibi Muhamad Lutfi , Mahbubah Putri Sekar Giri Fatimah
Published: April 2024

The success of the Badan Narkotika Nasional (BNN) in protecting and saving the Indonesian people from stopping illegal drug trafficking in 2021 has exceeded the target set. This can be realized thanks to preventive campaigns, including Instagram social media. This research aims to present the results of a semiotic analysis of visual content uploaded by BNN via the BNN Cegah Narkoba Instagram account (@bnn_cegahnarkoba) from January to June 2022 based on their success in reducing the rate of triggering and illicit circulation of drugs in Indonesia throughout 2021. The method used in this study is the triadic semiotic analysis by Charles Sanders Peirce, who interprets the relationship between objects through DKV elements, DKV principles, and typography in contents with a representamen that produces an interpretant. The results of this research show that the meaning of the BNN Cegah Narkoba’s campaign content tends to display anonymous visual representations of its audience and places more emphasis on preventive verbal messages. Additionally, visual associations to symbols of popular fictional characters are also used so that the range of impact can be even wider. This tendency is carried out based on compliance with media ethics and consideration of the target audience dominated by young people. Keywords: anti-drug campaign, BNN, Peirce’s semiotics
Cuidados nutricionais e hidratação artificial em paciente sob cuidados paliativos: uma reflexão em bioética médica
Authors: Brito Tayane Ferreira , Silva Beatriz Fiúza Gondim da , Lopes Pâmela dos Anjos Ferreira , Nunes Juscimar Carneiro , Santana André Bento Chaves , Byk Jonas
Published: April 2024

Objetivo: Explorar a literatura atual sobre os aspectos bioéticos associados à nutrição e hidratação artificial em pacientes sob cuidados paliativos. Revisão bibliográfica: O objetivo principal no âmbito dos cuidados paliativos se concentra na melhoria da qualidade de vida de pacientes que enfrentam doenças graves e incuráveis, prevenindo e aliviando o sofrimento de diversas esferas, como fisiológicas, psicossociais e espirituais, tornando a gestão de sua nutrição e hidratação uma questão complexa e delicada. Pacientes em cuidados paliativos podem sofrer alterações na via de alimentação, passando da via oral para artificial, com isso, a passagem da via de alimentação de oral para um método artificial tem um impacto significativo na vida e nos hábitos do doente, além de ser considerado um método invasivo, que acarreta um risco significativo, devendo ser cautelosa a sua utilização. Dessa forma, o suporte nutricional e hidratação artificial na assistência paliativa requer discussões constantes sobre a ética e bioética, requerendo uma reflexão compartilhada, complexa e interdisciplinar, pois lidam diretamente com a dor, perda e o sofrimento diante da morte iminente dos pacientes sem possibilidades terapêuticas de cura. Considerações finais: Os paradigmas entre iniciar ou suspender a hidratação e nutrição em pacientes no final de vida são desafios que envolvem questões éticas, portanto conhecer os princípios que regem a bioética faz-se oportuno para proporcionar o cuidado individualizado, e sobretudo o respeito à autonomia do paciente, que são pilares que podem auxiliar nas tomadas de decisões nessa fase terminal.
Primary central nervous system lymphoma: A mirror type presentation in an immunocompetent patient
Authors: Chávez Elizabeth Escamilla , Arce Julio César Delgado , Perea Edinson David Berrio , Pedraza Abraham Gallegos , Ávila Ana Itiel Jimenez , Quezada David Eduardo Aguirre , Suárez Pablo David Guerrero
Published: April 2024

Background:

Primary central nervous system (CNS) lymphoma is a very rare extranodal non-Hodgkin lymphoma. The bilateral pattern, as we call it “mirror type”, has been identified in other CNS lesions such as gliomas, metastases, and demyelinating lesions, so the differential diagnosis includes imaging studies such as magnetic resonance imaging contrasted with spectroscopy, ruling out immunodeficiency or metastatic disease.

Case Description:

A 65-year-old female presented progressing headache, loss of memory and language alterations, as well as sensory alterations. Neuroimaging showed the presence of two equidistant periventricular lesions at the level of both ventricular atria, a spectroscopy study suggestive of malignancy. Serological studies showed no evidence of immunodeficiency or the presence of positive tumor markers; however, a biopsy was performed, which revealed a histopathological result of primary lymphoma of the CNS.

Conclusion:

In neuro-oncology, primary CNS tumors with multiple lesions are rare, even more, the “mirror type” lesions. Lymphomas are lesions that can present in different ways on imaging and clinical presentation. These tumors that present a vector effect due to their size, perilesional edema, or that lead to loss of neurological function are highly discussed in diagnostic and surgical treatment. Due to their prognosis, action on diagnosis and treatment must be taken as quickly as hospital resources allow.

Published: April 2024

L’arène foncière du centre-ouest ivoirien est un théâtre âprement disputé par les principales populations sédentaires de la localité. Pour en connaître les déterminants, l’étude s’est focalisée sur la discrimination foncière de minorités sédentaires dans la sous-préfecture de Sinfra avec pour objectif de connaître les facteurs explicatifs de la stigmatisation et du rejet foncier des couches sociales minoritaires. Un échantillon de soixante-huit personnes a donc été interrogé sur une base non probabiliste, précisément l’échantillon par choix raisonné et par choix accidentel. Les résultats révèlent qu’une double série de facteurs sont à l’origine de cette discrimination foncière : facteurs endogènes (sentiment d’envahissement foncier des autochtones, réaction sociale des autochtones face aux méthodes de corruption foncière des allogènes) et exogènes aux acteurs ruraux (pesanteurs culturelles, eﬀets de l’urbanisation et du lotissement des terres cultivables). Ces résultats, tout en validant les travaux qui décrivent les populations minoritaires comme victimes de stigmatisation et de clichés stéréotypés, suggèrent l’intégration des allogènes dans les Comités Villageois de Gestion Foncière Rurale, la réduction des expropriations foncières d’allogènes, la restitution des terres réquisitionnées pendant les violences postélectorales de 2010 et la formalisation du processus d’acquisition des terres rurales à Sinfra.

Published: April 2024

This study focuses on conceptualization and development of a battery management system (BMS) with two main functions, battery monitoring and management, in the context of brushless direct current motors (BLDCs). The main challenge in variable estimation is to protect the battery from potential risks during the charge and discharge cycle. The new proposed resolution combines a comprehensive BMS with monitoring capabilities for charge (SoC), health (SoH), voltage, current and battery temperature. In addition, a protective mechanism is incorporated to prevent variables from overshooting safety parameters. This research uses two different methodologies for estimating SOC, coulomb counting and open circuit voltage. In experimental tests, resistance potentiometers of 1,650, 3,300 and 0 were used, with SoC estimates of 37%, 19% and 65%, while coulomb counting method has a marginal error of 1.13%. On the contrary, the open-circuit voltage method generated a SoC estimate of 0% for all potentiometer resistance, with an error rate of 0.64 %. As a result, the open circuit voltage method is chosen because of its superior accuracy compared to the coulomb counting method. The state assessment of the battery showed a value of 100% after seven cycles. In addition, a protective system has been implemented to ensure that battery variables remain within the safe thresholds throughout the charge and discharge process. Consequently, the implementation of this BMS is expected to significantly improve overall performance and extend battery life.
Performance Analysis of Permanent Magnet BLDC Motor for Reducing Cogging Torque Using Taguchi Method
Authors: Ferdyanto Ferdyanto , Fatwa Gumilang , Erlangga Augusta , Marbawi Idris
Published: April 2024

An electric motor is an electromagnetic machine commonly utilized across various industries and automotive products. One prevalent type of electric motor employed in electric vehicles is the Permanent Magnet Brushless DC Motor (PM-BLDC), a brushless motor employing permanent magnets. However, despite its efficiency, permanent magnet motors often experience vibrations that can disrupt their performance. This research aims to optimize the existing BLDC motor design, with a specific focus on reducing the existing cogging torque. Initially, the existing design exhibited a cogging torque level of 0.21482 Nm. The optimization process involved modifications to several key design parameters, such as air gap, magnet thickness, magnet type, and slot opening width. In previous research, only comparisons were made between stator slot designs, which proved to be less effective as significant differences were not evident in the results of the comparative analysis of BLDC motor designs. So, in this research, the Taguchi method was utilized for the optimization process due to several advantages it offers. Through an analysis of means and variance, the optimization process successfully achieved a significant reduction in cogging torque by 0.099744 and an increase in efficiency by 0.6%. The results of the optimized permanent magnet BLDC design indicated a cogging torque value of 0.115072 Nm and an efficiency of 86.64% at an operational motor speed of 1500 rpm. This research provides a substantial contribution to the development of more efficient electric motors suitable for various applications.

The process of converting solar cell electrical energy is a form of utilizing environmentally friendly alternative energy sources (renewable energy). The conversion system is in the form of PV panels that are installed in a location exposed to sunlight and unobstructed. Monitoring is carried out when the sun shines from morning to evening. The location of the panel is in the vehicle parking lot of the engineering faculty, while monitoring is carried out in the Control Laboratory of the Tanjungpura University Engineering Faculty, which is 300 meters away. Factors that determine the quality of PV panels are the system and dimensions. This shows that fluctuations in current (I), voltage (V) and power (P) need to be controlled so that load distribution and reserves can prevent reduced energy generation. Observation and control using Long Range Area (LoRa) radio transmission media connections, Internet of Things (IoT) and Programmable Logical Control (PLC) in real-time. Observation and test results show that energy generation has experienced an increase in temperature which has an impact on reducing power. Meanwhile, the effect of the distance between the installed panels produces an average delay of 7 milliseconds (midday conditions). Meanwhile, the Signal to Noise Ratio (SNR) value for data transmission is 30 dBm at the device frequency of 868.125 MHz. Baud rate 2400-9600 bps with a speed of 0.3 bps – 62.5 Kbps. The application of this system is a research novelty because it can determine and control the generation of electrical energy at minimum, maximum and optimum conditions with a certain distance between the observer and the installed panel.

Published: April 2024

Metal complexes have emerged as a promising source for novel classes of antibacterial agents to combat the rise of antimicrobial resistance around the world. In the exploration of the transition metal chemical space for novel metalloantibiotics, the rhenium tricarbonyl moiety has been identified as a promising scaffold. Here we have prepared eight novel rhenium bisquinoline tricarbonyl complexes and explored their antibacterial properties. Significant activity against both Gram-positive and Gram-negative bacteria was observed. However, all complexes also showed significant toxicity against human cells, putting into question the prospects of this compound class as metalloantibiotics. To better understand their biological effects, we conduct the first mode of action studies on rhenium bisquinoline complexes and show that they are able to form pores through bacterial membranes. Their straight-forward synthesis and tuneability suggests that further optimisation of this compound class could lead to compounds with enhanced bacterial specificity.

Published: April 2024

The human gut has emerged as a highly promising candidate for predicting the onset of pathologies and monitoring disease pro-gression. The gut microbiota plays a crucial role in maintaining gut homeostasis, modulating immune responses, metabolizing nutri-ents and regulating host physiology. These functions have been linked to the interplay between gut bacteria and colonocytes in the human large intestine. At present, we lack high-throughput techniques capable of monitoring the crosstalk between these species on a molecular level in real time. In this work, we develop a model of the human large intestine in a 5 mm NMR tube that accounts for the intraluminal, mucosal and colonocyte spaces. Through the use of chemical shift imaging techniques, we follow changes to the pH in real time across different parts of the simulated large intestine and monitor the crosstalk between colonocytes and gut bacteria mediated by short-chain fatty acids. Finally, we demonstrate the in vitro model’s utility in the real time monitoring of the effects of exogenous small molecules on the production of metabolites and changes in pH in the large intestine. Our in vitro set-up provides an easily accessible model of the human gut that has the potential to allow detection of molecular-level changes associat-ed with disease development through inoculation with a patient’s cells or gut bacteria, as well as providing a high-throughput plat-form for drug discovery and toxicity testing.

The assembly of artificial metalloenzymes provides a second coordination sphere around a metal catalyst. Such a well-defined microenvironment can lead to enhancing the activities and selectivity of the catalyst. Herein, we present the development of artificial hydroxylase (ArHase) by embedding a Fe-TAML (TAML = Tetra Amide Macrocyclic Ligand) catalyst into a human carbonic anhydrase II (hCAII). Incorporation of the Fe-TAML catalyst ([BS-Fe-bTAML]–) within hCAII enhanced the Total TurnOver Number (TTON) for the hydroxylation of benzylic C–H bonds. After engineering a thermostable variant of hCAII (hCAIITS), the resulting ArHase, [BS-Fe-bTAML]– · hCAIITS, was subjected to directed evolution using cell lysates in a 384-well format. After three rounds of laboratory evolution, the best-performing variants exhibited 36-fold enhancement in the initial rate (124.4 min-1) and 2.8-fold enhancement in the TTON (2629 TTON) for the hydroxylation of benzylic C–H bonds compared to the free cofactor. We surmise that an arginine residue introduced in the course of directed evolution engages in hydrogen bonding with [BS-Fe-bTAML]–. This study highlights the potential of relying on a thermostable host protein to improve the catalytic performance of the hCAII-based ArMs.

Laser-induced graphene (LIG) has emerged as a promising solvent-free strategy for producing highly porous, 3D graphene structures, particularly for electrochemical applications. However, the unique character of LIG and hydrogel membrane (HM) coated LIG requires accounting for the specific conditions of its charge transfer process. This study investigates electron transfer kinetics and the electroactive surface area of LIG electrodes, finding efficient kinetics for the [Fe(CN)6]3-/4- redox process, with a high rate constant of 4.12 x 10-3 cm/s and an electroactive area 28 times higher than the geometric area. The impact of polysaccharide HM coatings (cationic chitosan, neutral agarose and anionic sodium alginate) on LIG's charge transfer behavior is elucidated, considering factors like Ohmic drop across porous LIG and Coulombic interactions/permeability affecting diffusion coefficients, estimated from amperometry. Experimental findings are supported by ab-initio calculations showing a electrostatic potential map’s negative charge distribution upon chitosan chain protonation, having an effect in over a two-fold redox current increase upon switching the pH from 7.48 to 1.73. This feature is absent for other studied HMs. It was also revealed that the chitosan's band gap was reduced to 3.07 eV upon acetylation, due to the introduction of a new LUMO state. This study summarizes the operating conditions enhanced by HM presence, impacting redox process kinetics and presenting unique challenges for prospective LIG/HM systems’ electrochemical applications.
Star-shaped conformers generated by co-evolutionary docking predict cross-fitting glycoprotein trimer pre-fusion interfaces on VHSV fish rhabdovirus
Authors: coll julio
Published: April 2024

Despite the abundant diseases caused by rhabdoviruses on plants, animals and men, there are no approved therapeutic drugs. This work targeted viral hemorrhagic septicemia viruses (VHSV), a group of representative rhabdoviruses causing devastating world-wide diseases on fish farmed-species. In particular, their glycoprotein (gpGVHSV) trimers were computationally targeted at its earliest pre-fusion inner interface. Co-evolution initiated from an optimized 2D-molecular parent and the corresponding gpGVHSV -conformer 3D cavity, generated tens of thousands of raw-children, and selected hundreds of cross-fitting conformer variations in a few scaffolds. Their predicted drug-like high affinities in nanoMolar ranges, low toxicities and targeting the pre-fusion inner interface were confirmed by independent algorithms

Published: April 2024

Background: Carpal tunnel syndrome is a frequently observed condition affecting the wrists and fingers, characterized by numbness, tingling, and sometimes pain.
Objective: To evaluate and compare the efficiency of magnetic field therapy and ultrasound therapy in rehabilitating women with carpal tunnel syndrome (CTS).
Patients and Methods: Forty women with mild to moderate CTS were included in the study, and an electromyography (EMG) and examination confirmed the diagnosis. The participants were assigned into two groups. Group A received magnetic field therapy, and Group B received ultrasound therapy. Patients for each group received a six-session clinical evaluation. The outcomes included the Boston Carpal Tunnel Syndrome Questionnaire (BCTSQ), handgrip strength, wrist joint movements (flexion and extension), as well as the Visual Analogue Scale (VAS).
Results: The paired t-test analyses demonstrate a significant improvement in the Boston questionnaire and VAS in both intervention groups at a P-value ≤0.05. The independent sample t-test analysis for post-intervention for both groups showed superiority for magnetic field therapy; no significant differences were observed in the improvement of wrist movement (Flexion = 0.66, Extension = 0.71); the Visual Analog Scale (VAS) has been improved in both treatment groups with dominance for ultrasound therapy.
Conclusion: Both magnetic field and ultrasound therapy effectively treat women with carpal tunnel syndrome. Magnetic field therapy was statistically superior to ultrasound.

Ramadan Fasting in Relation to Salivary Uric Acid and Selective Physical Parameters
Authors: Abdul Kareem Hussein , Ryam , Hussein Awn Baydaa
Published: April 2024

Background: Ramadan is the holy month in which all Muslims abstain from eating and drinking from sunrise to sunset. The impact of Ramadan fasting on the oral cavity and saliva needs more attention because of the important function of saliva in the protection of the mouth.
Objective: To determine the impact of Ramadan fasting on salivary uric acid, flow rate, and pH among Iraqi male dental students.
Patients and Methods: The subject population consisted of thirty healthy male dental students (College of Dentistry/University of Baghdad) with an age range of 20–23 years who intended to fast the whole of Ramadan (1443 Hijri calendar). Saliva samples were obtained from all dental students one week prior to the start of Ramadan, the last week of Ramadan, and one month after the end of Ramadan. The salivary flow rate was calculated, and the salivary pH was measured using a digital pH meter. Then a saliva sample was analyzed to detect the concentration of uric acid by using the spectrophotometer.
Results: The data analysis for this study revealed that the salivary flow rate decreased from baseline to Ramadan and then increased again after one month of Ramadan with significant differences (p<0.05). While salivary uric acid increased continuously with significant differences from baseline to Ramadan and after one month of Ramadan fasting (p<0.05), on the other hand, salivary pH showed no significant differences (p > 0.05) among the three time periods of the study.
Conclusion: Saliva was affected by Ramadan fasting through a decrease in salivary flow rate during fasting and a return to normal salivary flow rate after the end of Ramadan. In addition, uric acid, which acts as a salivary antioxidant, shows an increase during Ramadan fasting.

Published: April 2024

Background: Nanoparticles are increasingly being used as an alternative antibiotic to target microorganisms, particularly for treating bacterial infections. In current study it was recognized processes such as metal ion release, induction of oxidative stress, and non-oxidative mechanisms. Developing resistance to nanoparticles is challenging for bacterial cells due to the multiple simultaneous actions against microorganisms, and require several simultaneous gene alterations within the same bacterial cell.
Objective: To determine the effect of the titanium dioxide nanoparticles (TiO2NPs) on the activity of the same bacteria that participate in dental caries (Staphylococcus aureus and Escherichia coli).
Patients and Methods: The study included 50 patients who attended the dental clinic and took the samples by the wooden swap from the molar area (cervical area of inflamed gingiva and same samples taken from occlusal surface of molar). The collected samples were cultured on “Mannitol salt agar, Blood agar, and MacConkey's agar plates” for separation of the needed bacteria (Staphylococcus aureus and Escherichia coli) that showed wide spreading in the oral cavities and dental carries. TiO2NPs are then created using pulse laser ablation, followed by coating preparation the nanoparticles materials (using a hybrid sol-gel and organ silicate nanoparticles), and finally the prepared nanoparticles to the coating solution and local paint was used for antimicrobial activity of the separated bacteria using different concentrations of TiO2 in the cultures.
Results: Characterization showed the phase of the TiO2NPs was spherical, with very few irregularly shaped particles, and had an average small size in millimeters. Antimicrobial activity results showed a strong bactericidal effect against Gram-positive bacteria and demonstrated greater sensitivity to TiO2 nanoparticles at lower concentrations when compared to Gram-negative bacteria.
Conclusion: It was shown that nanotechnology promise in treating various infections caused by bacteria, including dental caries. Notably, nanoparticles have demonstrated broad-spectrum antibacterial effects against Gram-positive bacteria.
“Co-Radicalization”: A Scientific Lens Proposal to Understand the Social Movements in Turkey
Authors: Kaya Ayhan , Koca Metin
Published: April 2024

The term co-radicalization refers to intergroup hostilities leading to conflicts through cycles of reciprocal threat. This article explores the concept of co-radicalization in violent and non-violent terms and its potential application particularly in Turkey and broadly in the Middle East, a region characterized by ethnic, cultural and religious diversity, as well as socio-economic disparities. Drawing from the social fragmentations recently observed in Turkey, where scientific research on radicalism and co-radicalization is insufficient, the article offers several subjects of scrutiny, including (1) socio-economic co-radicalization between the native and migrant people in the fringes of the urban spaces, (2) the religious norm carriership led by the state institutions and the rise of “Deism” and atheism in response, and (3) the variety of non-violent radical expressions feeding each other, from music to satire. We conclude that the study of co-radicalization should be distinguished from the reductionist approaches to the concept, which tend to take terrorism and radicalism synonymously; the social scientific goal is to gain a deeper understanding of the complex dynamics behind societal divisions.
