KPU’s Strategy in Overcoming Double Data Issues in the Registration of 2024 Electoral Participants in Mojokerto City
Authors: Sabilah Ammaya , Nurjaman Asep
Published: April 2024

This article highlights the strategies employed by the General Election Commission (KPU) to address the issue of double data that emerged during the registration process of the 2024 General Election participants in Mojokerto City. This issue stems from the ineffectiveness of the Political Party Information System (SIPOL), evidenced by thousands of double data on party membership. Double data issues can pose a severe threat to the integrity of democratic elections. Hence, this research focuses on the KPU's efforts or strategies to maintain the accuracy and reliability of data. The formulation of these strategies prioritizes the implementation of the Electoral Governance Theory, with the primary focus on analyzing and finding solutions to existing issues. This research applied a qualitative approach with a case study model. Data was collected through observation, in-depth interviews, and documentation. The results of this research indicate that based on Decree No. 260 of 2022, KPU has conducted Administrative Verification to identify potential cases of dual memberships and ineligible memberships. This process involves four main stages, including registration, administrative verification, factual verification, and determination. This research also aims to discover the issues faced by the General Election Commission (KPU) of Mojokerto City during the verification process.

Published: April 2024

Las personas con Trastorno del Espectro Autista (TEA) presentan dificultades de lenguaje y comunicación. La conciencia pragmática es uno de los componentes lingüísticos más estudiados en TEA grado 1 asociado al Síndrome de Asperger, e influye a la vez en el desarrollo de las áreas lingüísticas (Crespo-Eguilaz et al., 2016). El objetivo de esta investigación fue, por un lado, analizar los rasgos de la comunicación pragmática del alumnado con TEA grado 1 y, por otro, realizar una comparativa sobre el uso pragmático del lenguaje y la comunicación social paralingüística con un grupo con desarrollo típico. La muestra está conformada por 8 niños (4 con TEA grado 1 y 4 con desarrollo típico). El análisis de los datos se ha realizado a través de las pruebas U de Mann-Whitney y resúmenes de casos. Para la recogida de datos, se usaron los cuestionarios de cribaje ASSQ y AQC para corroborar la existencia o no del trastorno. Para valorar el lenguaje, se utilizaron las pruebas del CELF-5 que componen la Puntuación Principal del Lenguaje (PPL). Finalmente, para evaluar la conciencia pragmática, se utilizó la adaptación al castellano del Children´s Communication Checklist. Cuantitativamente, los resultados revelaron la existencia de dificultades en las habilidades pragmáticas en el alumnado TEA grado 1. Continuando con el perfil lingüístico, no se mostraron diferencias significativas en las demás áreas del lenguaje (fonológica, morfológica y semántica). El presente trabajo constituye una primera aproximación al análisis del perfil lingüístico del alumnado TEA grado 1, haciendo hincapié en la comunicación pragmática.

Splenic hematoma and hemoperitoneum in a Thoroughbred racehorse after racing
Authors: Neville Erin , Pigott John
Published: April 2024

OBJECTIVE

To describe the clinical presentation of a Thoroughbred filly with acute hemoperitoneum from a splenic source immediately after racing.

ANIMAL

A 3-year-old Thoroughbred filly used for racing and that had raced shortly before presentation to the hospital.

CLINICAL PRESENTATION, PROGRESSION, AND PROCEDURES

On presentation, the filly was quiet, alert, and responsive with a heart rate of 76 beats/min, pale mucous membranes, and absent borborygmi. All other physical examination parameters were within normal limits. Abdominal ultrasound was performed and revealed echogenic free abdominal fluid and a splenic hematoma. Abdominocentesis yielded sanguinous fluid with a PCV of 35%. The next day, repeat ultrasound revealed the splenic hematoma with capsular separation.

TREATMENT AND OUTCOME

The filly was treated overnight with isotonic crystalloid fluids and aminocaproic acid (40 mg/kg, IV, slow bolus over 30 minutes followed by 20 mg/kg, IV, q 6 h), potassium penicillin (22,000 IU/kg, IV, q 6 h), gentamicin (6.6 mg/kg, IV, q 24 h), and omeprazole (4 mg/kg, PO, q 24 h). The lowest PCV obtained from the filly was 36 hours after presentation. The filly stabilized with medical treatment and was discharged to a farm for further recuperation.

CLINICAL RELEVANCE

There are no published reports detailing hemoperitoneum of splenic origin in Thoroughbreds immediately after racing. Hemoperitoneum of splenic origin is not common in horses, with most cases of hemoperitoneum being secondary to acute trauma, neoplasia, parturition, or postoperative complications. While uncommon, this case raises awareness to another differential for a colicky horse immediately after racing.

Published: April 2024

Wiskott-Aldrich syndrome (WAS) is an X-linked disorder characterized by thrombocytopenia, eczema and immunodeficiency. Clinical features of the disease are highly varied; therefore, the diagnosis is sometimes difficult, especially in solitary cases or cases with milder forms of the disease. However, the identification of the WASP gene has made possible a definite WAS diagnosis for these cases. In this report, we present a 26-month-old boy who had received several ineffective treatments for chronic immune thrombocytopenic purpura. He was then suspected to have WAS because of the early onset of thrombocytopenia and small platelets. The diagnosis became definite with the detection of a de novo mutation at exon 4 of the WASP gene, Arg138Pro, through mutation analysis.

Published: April 2024

Patients with malformations of cortical development (MCD) present with a wide spectrum of clinical manifestations ranging from asymptomatic cases to those with epilepsy and neurodevelopmental problems. Thorough clinical delineation of patients with MCD may provide clues for future phenotype-genotype correlation studies. We studied clinical features of patients with MCD, including developmental risk factors and family history. We evaluated 10 patients with MCD at Hacettepe University Children's Hospital, Department of Pediatric Neurology. All patients underwent neurological evaluation with detailed medical and family history, and neuropsychological evaluation. Routine EEG and MRI were obtained. The patients were between 1 month and 19 years of age (mean: 6.1 +/- 4.4 years). Fifty-four patients were diagnosed with polymicrogyria (PMG), 23 patients with lissencephaly, 12 patients with schizencephaly, and 12 patients with heterotopia. Parents were relatives in 31.7% of the cases; consanguinity was most common in patients with lissencephaly and other MCDs with diffuse/bilateral involvement. Initial clinical presentation was seizures in 61.4% of the cases, developmental delays in 12.9%, and microcephaly in 9.9%. Neurological evaluation revealed most severe abnormalities in patients with lissencephaly, and relatively better outcome in patients with heterotopias. Cognitive functions were better in patients with heterotopias compared to other groups. Overall, 71.3% of patients ha epilepsy. In conclusion, initial presentation and clinical course of patients with MCD are variable and seem to be correlated with the extent of cortical involvement. Epilepsy and mental retardation are the most common problems. The most severe clinical outcome was seen in patients with lissencephaly.

Published: April 2024

The MBX gene is a novel paired-type homeobox gene. It plays a number of critical roles in the development of the eyes in the zebrafish. The knockdown of the mbx expression by morpholino antisense oligonucleotides leads to a reduction in the size of eyes and tectum in the zebrafish. We investigated whether the human MBX gene was associated with susceptibility to microphthalmia by analyzing four Korean families demonstrating microphthalmia with congenital cataract. Mutational analysis was performed on the human MBX gene using these families. However, no mutations could be detected. Therefore, no indications were found for an association between the MBX gene and microphthalmia with congenital cataract in humans.

Published: April 2024

Lamotrigine has been considered a safe new-generation antiepileptic drug during the perinatal period for both mothers and infants. Despite the concerns regarding its possible teratogenic effect, very limited data have been reported on the adverse effects of perinatal lamotrigine exposure. Herein, we report a case of an infant with hypotonicity and poor feeding who was exposed to lamotrigine in utero. The drug interaction probability scale indicated a probable relationship between sepsis-like symptoms and exposure to lamotrigine and valproic acid in utero in this infant.

Published: April 2024

Este artigo analisou a distribuição espacial do risco de seguros agrícolas para culturas temporárias e permanentes, atendidas pelo Programa de Subvenção ao Prêmio do Seguro Rural (PSR), na região Sul do Brasil, no período de 2006 a 2021. Para isso, o Índice de Sinistralidade e o Índice de Risco Relativo foram utilizados como indicadores. Além deles, aplicou-se o Índice de Moran para identificação de regiões em que há maior ou menor concentração de risco. Os resultados evidenciaram a concentração dos recursos do programa em poucas culturas agrícolas para ambos os grupos estudados, temporárias e permanentes. Ainda assim, a oferta de seguro diversificada entre esses grupos mostrou-se como estratégia de redução de riscos sistêmicos. Ademais, o Índice de Moran revelou que o Rio Grande do Sul concentra aglomerados de municípios com alto risco considerando as culturas temporárias, principalmente nas mesorregiões Sudeste, Noroeste, Centro Ocidental e Centro Oriental, onde a concentração de recursos deve ser mais evitada.

Authors: Aziz Musharraf , Hassan Ahdi , Aljamili Omar
Published: April 2024

Contemporary ESL education focuses on screen-based reading, specifically in the context of university level learners. Also, a sudden shift from paper bound reading activities to screen-based tasks was inevitable in response to COVID-19 outbreak. In this regard, the case of inferential and advanced level reading among the young ESL learners of developing countries appears researchable because of the general low digital literacy of these learners. This study, therefore, aimed to investigate the effect of reading mode shift from paper to screen on the inferential comprehension performance among Pakistani ESL learners at university level. A total of 426 undergraduate learners were sampled from Bachelor of Science program in a well-known university in the city of Lahore, Pakistan. Inferential reading was conceptualized through Bloom’s higher order thinking skills, that is, Analyzing, Evaluating and Creating skills therefore the reading comprehension test was based on these skills. Adopting sequential test administration, first the paper-based reading test, and later the screen-based reading was given. The obtained data were analyzed using Rendell’s XCALIBRE and SPSS V. 26.0. The logit scale descriptives, learner ability (θ), and mean scores demonstrated that the learners performed significantly higher in the paper test as compared to screen test. Moreover, it was found that the effect of reading mode shift was larger in Creating skill. The findings may have significant implications for reading mode selection, enhancement of digital competence and effect of reading mode shift in developing countries with inadequate IT facilitation and digital literacy among ESL learners.

Background:

Orbital tumors, arising within the bony orbit and its contents, present diverse challenges due to their varied origins and complex anatomical context. These tumors, classified as primary, secondary, or metastatic, are further subdivided into intraconal and extraconal based on their relationship with the muscle cone. This classification significantly influences surgical approach and management. This study highlights surgical experiences with orbital tumors, underscoring the importance of tailored surgical approaches based on the lesion’s site and its proximity to the optic nerve.

Methods:

This retrospective study at the National Institute of Cancer’s Head and Neck Department (2005–2014) analyzed 29 patients with orbital tumors treated with surgery, radiotherapy, chemotherapy, or combinations of them. Patient demographics, tumor characteristics, and treatment responses were evaluated using computed tomography (CT), magnetic resonance imaging, and positron emission tomography-CT imaging. Malignant tumors often required orbital exenteration and reconstruction, highlighting the study’s commitment to advancing orbital tumor treatment.

Results:

29 patients (18 females and 11 males, age 18–88 years, mean 53.5 years) with orbital tumors exhibited symptoms such as decreased vision and exophthalmos. Tumors included primary lesions like choroidal melanoma and secondary types like epidermoid carcinoma. Treatments varied, involving a multidisciplinary team for surgical approaches like exenteration, with follow-up from 1 to 9 years. Radiotherapy and chemotherapy were used for specific cases.

Conclusion:

Our study underscores the need for a multidisciplinary approach in treating orbital tumors, involving various surgical specialists and advanced technologies like neuronavigation for tailored treatment. The integration of surgery with radiotherapy and chemotherapy highlights the effectiveness of multidimensional treatment strategies.

Comparisons to experiments are important when developing kinetic models based on density functional theory (DFT) calculations. The comparisons are, however, often challenging due to the assumed uncertainties in the energies from which the kinetic parameters are calculated. Here, we introduce a genetic algorithm to adjust the DFT-energies to better match experimental XPS data, using CO hydrogenation on Rh(111) as an example. The adjustments are made to adsorption energies, adsorbate-adsorbate interactions, XPS energies and peak shapes. While these parameters improve the experimental agreement considerably, the required changes to the DFT energies are relatively large, which indicates the need for refined treatments of, for example, possible surface species and reaction steps, surface inhomogeneities, or higher levels of electronic structure calculations. We propose the genetic-algorithm based method as a general tool for assessment of computational models.
How domain segregation in ionic liquids stabilizes nanoparticles and establish long-range ordering – a computational study
Authors: Bernardino Kalil
Published: April 2024

Due to their physical properties including high thermal stability, very low vapor pressure and high microwave absorption, ionic liquids have attracted great attention as solvents for the synthesis of nanomaterials, being considered as greener alternatives to traditional solvents. While usual solvents often need additives to avoid nanoparticles coalescence, some ionic liquids can dispense their use, being able to stabilize nanoparticles in dispersion. In order to quantify how the ionic liquids can affect both the aggregation thermodynamics and kinetics, molecular dynamics simulations were performed to simulate the evolution of concentrated dispersions and to compute the potential of mean force between nanoparticles of both hydrophilic and hydrophobic nature in two imidazolium-based ionic liquids, which differ from each other by the length of the cation alkyl-group. Depending on the nature of the nanoparticle, structured layers of the polar and apolar regions of the ionic liquid can be formed close to its surface and those layers lead to activation barriers for dispersed particles to get in contact. If the alkyl group of the ionic liquid is long enough to lead to domain segregation between ionic and apolar portions of the solvent, the layered structure around the particle becomes more structured and propagates to several nanometers away from its surface. The leads to stronger barriers close to the contact and also in multiple barriers at larger distances that result from the unfavorable superposition of solvent layers of opposing nature when the nanoparticles approach each other. Those long-range solvent-mediated forces not only provide kinetic stability to dispersions, but also affect their dynamics and lead to a long-range ordering between dispersed particles that can be explored as a template for the synthesis of complex materials.

The proportional amounts of monomers within a copolymer will greatly affect the properties of the material. However, as known as composition drift, the monomer ratio in a copolymer can deviate from the value expected from the raw material ratio due to differences in monomer reactivity. Hence, it is therefore necessary to optimize the polymerization process on the basis that this inevitable composition drift will take place. In the present study, styrene-methyl methacrylate copolymers were generated using a flow synthesis system and the processing variables were tuned employing Bayesian optimization (BO) to obtain a target composition. Initial trials employed BO to produce four candidate points per cycle, completing the optimization within five cycles, and the solvent-to-monomer ratio was identified as the most important variable. Subsequent BO tests employed 40 points per cycle and established that multiple sets of processing conditions could provide the desired composition, but with variations in the physical properties of the copolymers. The role of each variable in the radical polymerization reaction was elucidated by assessing the extensive array of processing conditions while evaluating several broad trends. The proposed model confirms that specific monomer proportions can be produced in a copolymer using machine learning while investigating the reaction mechanism. In the future, the use of multi-objective BO to fine-tune the processing conditions is expected to allow optimization of the copolymer composition together with adjustment of physical properties.
Beti’s Perspective: Using Critical Race Theory’s Composite Counterstory to Interrupt Antiracism Projects in Vancouver, BC
Authors: Birk Manjeet
Published: April 2024

Building on research conducted in feminist organizations in Vancouver, British Columbia, on the unceded territories of the xʷməθkʷəy̓əm (Musqueam), Sḵwx̱wú7mesh (Squamish), and səlilwətaɬ (Tsleil-Waututh) Nations, this paper explores the role, relationship, and responsibility of advocating for antiracism and social justice in the context of antiracism projects in feminist nonprofit organizations. In doing so this paper asks: What do antiracism projects look like in feminist organizations? And how are these projects informed or interrupted by racialized and Indigenous activists within these spaces? Using critical race theory’s composite counterstory, this paper uses storytelling methodologies to understand how racialized settlers and Indigenous folks can collaborate and thrive – as they have been doing – on occupied unceded territories in Canada. Based on a series of interviews with racialized and Indigenous activists engaging in feminist nonprofit organizations, these stories shed light on contemporary realities of colonization, including collaboration within white settler systems.
The Hero, the White Savior, and the Smuggler: Criminalized Figures in the Landscape of Solidarity Toward Migrants
Authors: Geeraert Jérémy
Published: April 2024

One recent shift in the ever-expanding crackdown on migration and implementation of a hostile environment for migrants in the EU has been the criminalization of migrant solidarity. Using various legal tools, EU governments have been trying to hinder solidarity actions from civil society. In particular, a narrative depicting civilians helping migrants as criminals has been elaborated by European organizations and strengthened by far-right groups and dominant press outlets. In reaction, a counter-narrative has been constructed and spread by pro-migrant groups and liberal media, which presents criminalized activists as criminalized heroes and their actions as humanitarian. Based on a critical discourse analysis of academic texts, press articles, and empirical research with pro-migrant activists, this article examines two criminal figures from the civilian search and rescue field: the “activist associated with smugglers” and its counterpart, the “criminalized hero.” Through the lens of figuration of crime and social justice, the article brings a new understanding of the de- and repoliticization processes that occur in the field of humanitarian help and migration. By analyzing these two figures, the paper also contributes to a better understanding of the competing moral orders underpinning criminal and social justice claims in the field of solidarity toward migrants. On the one hand, the figure of the activist associated with smuggler is part of a criminal justice narrative depicting migration as a threat to political, social, and economic stability. On the other hand, the criminalized hero figure includes a counter-narrative to this moral order based on the defense of a social justice frame of solidarity and the protection of human rights. Within the pro-migrant activist’s scene, the criminalized hero and its social justice frame are criticized for reproducing racist and post-colonial practices of humanitarianism.

Mobility of physically disabled persons is a concerning social issue nowadays. The basic Tricycle is a three- wheeled design, pedaled by disabled persons in the side and seat in the middle for sitting arrangement. They use only one hand to steer the handle because other-hand is used to rotate the pedal. Our aim is to design a low-cost tricycle that will allows person to accelerate and steer the tricycle from a single place. The way the Bike Chair works is the back is essentially a regular bicycle, but the front turns it into a tricycle, and sort-of makes it a wheelchair and bicycle combo. The disabled passenger sits on the front two wheels, as the driver uses their front wheels to steer the bike. The passenger has buckles and strap to secure the min place and top even them from falling out of the chair during the bike-ride. Furthermore, the tricycle's compact size, maneuverability, and zero emissions make it an attractive option for reducing traffic congestion and pollution in densely populated urban areas. Future research directions include optimization of battery and motor technologies for enhanced performance and efficiency, as well as integration of smart features for improved user experience and safety.

The height adjustable wheel chair focuses on meeting the needs of paraplegics ‘ patients and the poor disabled persons who desire to perform certain tasks independently and privately, such as sitting on the chair, picking items from shelves, cupboard and wardrobes at the standing height of average human being. Hence, an appropriate wheelchair to meet their need has been designed using low cost and readily available materials to achieve this product. The existing wheelchair was evaluated before its modification was done in justifying the established improvement. To achieve this, the wheel chair was redesigned with a low centre of gravity to enhance stability with the introduction of sizeable hydraulic jack to aid height adjustment. By controlling hydraulic pressure, users can elevate or lower the seat to preferred heights, facilitating ease of access to various surfaces and environments. Additionally, the hydraulic system offers stability and durability, ensuring safe operation for users of different body weights and sizes Performance evaluation of the developed wheelchair was carried out to ensure standardization in meeting the needs of the intended users. On basis of ease of operation to a chosen height of 2m using pulses generated, 79 pulses/ minutes was recorded for the improved wheelchair as against the 95 pulses/minutes of the existing wheelchair. Also it takes 28 seconds and 36 seconds for the modified and existing wheelchairs to reach the set height respectively. It offers confinement for adjustment to desired height position and provides mobility while at chosen elevated position.

Pro wheelchair users are at a height disadvantage during many function activities, such as transferring or reaching. Retrieving objects from the ground or a higher shelf while seated in the wheelchair can be both difficult and unsafe. Lateral transfers between surfaces at different heights can be hard and unstable. Sit-to-stand transfers are made simpler with a higher seat. This research project seeks to assist reach and transfers by designing a system to raise and lower a wheelchair seat over a 4’’ range. The project followed a multi-step iterative design process that included: needs assessment by conducting interviews and surveys, identify design needs from different stakeholder groups; analysis of stakeholder groups’ feedback and synthesis into design criteria; and creation of design concepts for the adjustable height wheelchair seat; evaluation of the design by setting up heuristic evaluation criteria and performance of user testing; design revision based on user’s test performance and feedback. The design process included fabricating and testing of various concepts, validating design through user testing, and addresses technology transfer of the device.

One important medical procedure that necessitates puncturing the skin is hemodialysis (HD). But there is a serious chance that blood will spill from a dislodged needle, endangering the lives of the patients. Numerous devices that use optical or electrical methods to identify blood loss during HD have been proposed in the past. Sadly, multi-bed monitoring was not feasible with these techniques, which were limited to single-point detection only. An array-sensing patch has been proposed as a novel wearable device to monitor blood loss during HD in response to these restrictions. Risk levels can be measured and transmitted using the array sensing patch in conjunction with a wireless module and mapping circuit. This has the potential to greatly improve health care worker productivity and eliminate erroneous risk levels. In addition to lowering false alarms, this can greatly improve health care personnel' productivity. Extensive experimentation results show that up to 0.1 mL of blood loss can be detected a teach spot in the sensing array. In addition, the array sensing patch includes an 8-hour risk level monitoring system, which notifies medical staff of relevant patient danger. A more effective and efficient means of monitoring blood leakage and potentially saving lives, the suggested device is a game-changer in the field of hemodialysis.

Electric vehicles rely on batteries, which are a significant component of their overall performance and efficiency. Monitoring battery health in real-time helps ensure optimal performance, extends battery lifespan, and prevents unexpected failures, thereby improving the overall reliability and longevity of e-vehicles. Real-time monitoring allows fleet managers and vehicle owners to track battery state of charge (SoC), state of health (SOH), depth of discharge (DOD) and predict remaining range accurately. This helps drivers plan their routes better and minimizes the risk of running out of battery power during trips. Real-time tracking enhances the safety and security of e-vehicles. In case of theft or unauthorized use, the system can provide location information to aid in recovery. Additionally, in case of accidents or emergencies, the system can alert authorities and dispatch assistance promptly.
