A Portrait of My Father
Authors: Butt Nadia
Published: October 2024

This work of life writing aims to piece together my late father, Muhammad Iftikhar Butt, who passed away on 20 of September 1996, in Lahore, Pakistan, when I was a teenager. A loss of a parent is a great tragedy and an emotional trauma, but this tragedy and trauma are deeper when the child has not mourned the loss but has erased it from its memory. By pondering father-daughter relationships in patriarchal cultures and gender dynamics in nuclear families, I re-member the forgotten bits of the past not only to mourn my father after more than two decades but also to commemorate the extraordinary phases of his fatherhood. Since my father has left behind no traces of his past life, the only way to bring him back to life is through my words – written words. With the help of shards and scraps of memory – some vivid, some fading – I seek to put the fragments of his life together to understand him long after his death due to my inability to understand him in his life. Indeed, I finally manage to re-collect him and see him as a person rather than a parent.
Research Trends on Metabolic Syndrome in Digital Health Care Using Topic Modeling: Systematic Search of Abstracts
Authors: Lee Kiseong , Chung Yoongi , Kim Ji-Su
Published: October 2024

Background

Metabolic syndrome (MetS) is a prevalent health condition that affects 20%-40% of the global population. Lifestyle modification is essential for the prevention and management of MetS. Digital health care, which incorporates technologies like wearable devices, mobile apps, and telemedicine, is increasingly becoming integral to health care systems. By analyzing existing research trends in the application of digital health care for MetS management, this study identifies gaps in current knowledge and suggests avenues for future research.

Objective

This study aimed to identify core keywords, topics, and research trends concerning the use of digital health care in the management of MetS.

Methods

A systematic search of abstracts from peer-reviewed papers was conducted across 6 academic databases. Following eligibility screening, 162 abstracts were selected for further analysis. The methodological approach included text preprocessing, text network analysis, and topic modeling using the BERTopic algorithm.

Results

Analysis of the 162 selected abstracts yielded a keyword network comprising 1047 nodes and 34,377 edges. The top 5 core keywords were identified as “MetS,” “use,” “patient,” “health,” and “intervention.” We identified 12 unique topics, with topic 1 focusing on the use of telehealth for self-management of diabetes. The diversity of the 12 topics reflected various aspects of digital health care, including telehealth for diabetes management, electronic health records for MetS complications, and wearable devices for monitoring metabolic status. Research trends showed an expanding field of precision medicine driven by the demand for tailored interventions and the significant impact of the COVID-19 pandemic.

Conclusions

By analyzing past research trends and extracting data from scholarly databases, this study has provided valuable insights that can guide future investigations in the field of digital health care and MetS management.
How Do Scholars Conceptualize and Conduct Health and Digital Health Literacy Research? Survey of Federally Funded Scholars (Preprint)
Authors: Sakhuja Mayank , Yelton Brooks , Kavarana Simone , Schaurer Lauren , Rumthao Jancham Rachel , Noblet Samuel , Arent Michelle A , Macauda Mark M , Donelle Lorie , Friedman Daniela B
Published: October 2024

BACKGROUND

The concept of health literacy (HL) is constantly evolving, and social determinants of health (SDoH) have been receiving considerable attention in public health scholarship. Since a 1-size-fits-all approach for HL fails to account for multiple contextual factors and as a result poses challenges in improving literacy levels, there is a need to develop a deeper understanding of the current state of HL and digital health literacy (DHL) research.

OBJECTIVE

This study examined scholars’ conceptualization and scope of work focused on HL and DHL.

METHODS

Using a search string, investigators (N=2042) focusing on HL, DHL, or both were identified from the grantee websites of the National Institutes of Health RePORTER (RePORT Expenditures and Results) and the Canadian Institutes of Health Research. The investigators were emailed a survey via Qualtrics. Survey questions examined the focus of work; whether the investigators studied HL/DHL in combination with other SDoH; the frameworks, definitions, and approaches used; and research settings. We analyzed survey data using SPSS Statistics version 28 and descriptive analysis, including frequencies and percentages, was conducted. Chi-square tests were performed to explore the association between the focus of work, settings, and age groups included in the investigators’ research.

RESULTS

A total of 193 (9.5%) of 2042 investigators responded to the online survey. Most investigators (76/153, 49.7%) were from public health, 83/193 (43%) reported their research focused on HL alone, 46/193 (23.8%) mentioned DHL, and 64/193 (33.2%) mentioned both. The majority (133/153, 86.9%) studied HL/DHL in combination with other SDoH, 106/135 (78.5%) conducted HL/DHL work in a community setting, and 100/156 (64.1%) reported not using any specific definition to guide their work. Digital tools (89/135, 65.9%), plain-language materials (82/135, 60.7%), and visual guides (56/135, 41.5%) were the top 3 approaches used. Most worked with adults (131/139, 94.2%) and all races and ethnicities (47/121, 38.8%).

CONCLUSIONS

HL and DHL research largely considered SDoH. Multiple HL tools and approaches were used that support the examination and improvement of literacy and communication surrounding health care issues.
Phishing Attacks: A Forefront Threat in the Ongoing History of the United States Healthcare Industry (Preprint)
Authors: Mohammed Raoof Mohammed
Published: October 2024

BACKGROUND

Phishing is the most prevalent type of social engineering attack. These attacks are harmful in any domain, including the healthcare domain. They compromise individuals’ confidential information.

OBJECTIVE

However, this study investigates the types of phishing attacks experienced by the United States (US) healthcare industry.

METHODS

This qualitative study employs the phenomenological research method to explore and understand the lived experiences of phishing attacks in the US healthcare industry. The data were collected from the archived US healthcare breaches report. Although the report may not include detailed information about phishing attacks, data limitations are employed to ensure the study's validity.

RESULTS

However, findings have shown that phishing attacks caused an astonishingly high percentage of affected individuals, an unbelievable 95.5%, from 2014 to 2024, and there were no incidents for the Whaling, Smishing, Vishing, Clone, and Pharming attacks, except only one incident for the spear phishing attacks throughout that duration. Moreover, controlling phishing attacks could help reduce and mitigate the risk of other attacks. For safeguarded solutions in healthcare settings, this study strongly recommends following the National Institute of Standards and Technology (NIST) standards, such as Special Publication (SP) 800-66r2.

CONCLUSIONS

While there were no incidents for the Whaling, Smishing, Vishing, Clone, and Pharming attacks, the findings show only one incident for the spear phishing attacks. Moreover, phishing attacks are more severe and dangerous and can affect many individuals more than other attacks. Even though phishing comes in various forms and strategies, we concluded that controlling phishing attacks could help to reduce and mitigate the risk of other attacks. Further studies will be required to analyze the breach report deeply and confirm this statement.
Our study promotes implementing the National Institute of Standards and Technology (NIST) standards, such as the SP 800-66r2 in healthcare settings to minimize the potential risks of various phishing attacks. Overall, our study contributions include spreading awareness of phishing attacks and helping protect healthcare organizations from phishing attacks and other attacks. Furthermore, supporting the vital need for technology developers and engineers to develop robust security mechanisms against phishing attacks.
Behind Many Visages: The Waluku Cultivating Civilization Tour as Part of the Visitor Flow Management Program in the Borobudur District
Authors: Silviyani Asna
Published: October 2024

The Borobudur Temple is a vulnerable cultural heritage site confronting the challenge of overcrowding impacting site preservation, visitor experience, and economic viability. This study analyzed the extension of visitor flow management applications to the buffer zone in heritage locations, focusing on the enhancement of the trip experience. The Waluku: Cultivating Civilization sub-theme, integral to the Borobudur Trail of Civilization concept, has the ability to enhance preservation via the Visitor Flow Management Process, which encompasses three phases: restricted, redistributive, and interpretative. This research employed qualitative methods by gathering data through interviews, literature reviews, and observations. The research findings revealed that the three stages operate independently and do not significantly affect the preservation of the Borobudur Temple's physical and cultural assets. Restrictions could undermine the objective of enhancing engagement and interaction with culture and nature, rendering them less effective. Meanwhile, the other two stages had minimal impact due to infrequent reservations. Itineraries may vary based on demand, and there is no interpretative narrative concerning the relationship between relief and tourism activities. Conflicts of interest and insufficient local community engagement provide barriers to the program's development.

Authors: Putri Riyanda Daniati , Firmansyah Dian Bayu , Hartati Hartati
Published: October 2024

This research discusses the forms and functions of interrogative marker ka and defines its use in Japanese public service advertisements, which AC Japan distributes. The method that is used in this research is a descriptive qualitative study. The research data is sentences with interrogative marker ka, which is found in AC Japan advertisements distributed on Japanese television in the last five years (2017-2021). The theory of forms and functions of interrogative marker ka by Yokoyama (2013) was used in this research. The watch-note technique was used in this research to collect data that would be needed. The data were analyzed with formalist and functionalist approaches. After that, the data would be analyzed by aspects of speech that affect the forms and functions of interrogative marker ka. The result showed that the interrogative marker ka in AC Japan advertisements has a function to state common questions, rhetorical questions, conjectural questions, polar imperatives, and embedded questions. From these several functions, rhetorical questions are more widely used because advertising is an indirect communication medium, which still has to pay attention to the emphasis on the message to be conveyed.

Authors: Kristiawan Yohanes Angie , Adhitya Galant Nanta , Enjelin Eka Meysel
Published: October 2024

The dark triad personality is commonly understood in the field of psychological studies. However, the analysis of the dark triad is still relatively new in the realm of literary studies. This article presents the dark triad in the lyrics of Metallica’s songs “Master of Puppets” and “Sad but True”. The selection of these two songs is based on the popularity of the song and the choice of words that cause multiple interpretations among Metallica fans. The findings of this research show that there are three traits of the dark triad found in both song lyrics. Machiavellianism represents manipulation; narcissism represents self-admiration; psychopathy represents anti-social and cruelty. This article can hopefully provide in-depth understanding to listeners as the music from previous decades keeps making comebacks.
TRACING AMERICAN SPIRIT IN INDONESIA’S INDEPENDENCE: A HISTORICAL-COMPARATIVE STUDY
Authors: Pasha Nariza Ayu
Published: October 2024

The US and Indonesia, two countries that fought for freedom, are fascinating subjects to delve more into, despite their great distance from one another and their distant times of conflict. This research used a Transnational American Studies perspective and comparative-historical analysis. By using comparative historical analysis, this research aimed to explore the similarities and differences that exist in the journey of American independence and Indonesian independence. The results of this research showed that even though the independence movements in the US and Indonesia occurred several centuries apart, they had the same goal, namely opposing colonialism. Both showed the same enthusiasm to fight colonial power and the desire to determine the fate of their nation without interference from other parties. Thomas Paine and Bung Tomo through their writings and speeches led the spirit of independence in the US and Indonesia. Even though they use different communication styles, both have an impact in forming the spirit of resistance and unity of their nation. Additionally, by looking at the history of the struggle of the Indonesian people, it can be seen the spirit of freedom that the US promoted.

La situación-problema como unidad de análisis epistémico para el Trabajo Social Contemporáneo
Authors: Urbalejo Luna Cristian
Published: October 2024

El siguiente trabajo tiene como finalidad presentar lo que es una unidad de análisis epistémico y cómo este concepto puede ser relevante para el análisis de la epistemología del trabajo social. A partir de esteconcepto se presentan tres unidades de análisis dominantes en América Latina: las necesidades y losproblemas sociales, la cuestión social y la situación-problema. A partir de ello defiendo la tesis de quela situación-problema es una unidad de análisis epistémico mucho más adecuada en el trabajo social contemporáneo, toda vez que permite una transición mucho más clara de un análisis de lo social a la intervención en lo social. Se presentan argumentos y contrastes entre la situación-problema y las otras unidades de análisis epistémico, para comprender cuáles son las ventajas y desventajas de cada una de estas propuestas. Se concluye con la importancia de pensar en términos de unidades de análisis epistémico a la epistemología del trabajo social. Esto nos permite tener mayor claridad sobre cuáles son las herramientasepistémicas y las prácticas de intervención que se constituyen a partir de cada una de ellas.
Bancos Públicos + Agua Pública = ODS 6?
Authors: McDonald David A. , Marois Thomas , Spronk Susan
Published: October 2024

El Objetivo de Desarrollo Sostenible 6 pretende lograr el acceso universal a los servicios de agua y saneamiento para 2030; se espera que esto cueste un estimado de US$150 mil millones por año. ¿De dónde saldrán estos fondos? Una posibilidad es la financiación privada en forma de inversión directa de capital de empresas privadas de agua y préstamos de bancos comerciales. Sin embargo, la evidencia sugiere que las inversiones privadas en agua y saneamiento no se han materializado según lo planeado debido al perfil de riesgo-rendimiento del sector. El agua y el saneamiento son considerados "demasiado arriesgados" por los inversionistas privados y los rendimientos no son lo suficientemente gratificantes. Una alternativa que puede ayudar a cubrir el déficit de financiación del abastecimiento de agua y el saneamiento (WSS, por sus siglas en inglés) es una fuente de financiamiento pública aún sin explotar: los bancos públicos. Hay más de 900 bancos públicos en el mundo, con 49 billones de dólares estadounidenses en activos; sin embargo, han sido subestimados en gran medida como una fuente importante de financiamiento para el agua y el saneamiento y también han sido descuidados por la investigación académica y por las principales organizaciones políticas, como el Banco Mundial. Es necesario comprender mejor cómo se puede movilizar a los bancos públicos como financiadores eficaces del agua pública. En este artículo ofrecemos una breve historia de las prácticas de la banca pública en el sector del agua, revisamos sus pros y sus contras, y discutimos la importancia de la aparición de un nuevo tipo de operador público de agua y el potencial que estas entidades ofrecen para financiar en este sector.
Repensando los bancos públicos dinámicos para una transición verde y justa
Authors: Marois Thomas
Published: October 2024

Los bancos públicos son dominantes, con más de 900 en todo el mundo, y poderosos, con activos que se acercan a los 49 billones de dólares. Sin embargo, con demasiada frecuencia se perciben como instituciones financieras estáticas, basadas en teorías económicas que parten de nociones fijas de lo que es ser un banco de propiedad pública. Esto ha dado lugar a un debate polarizado en el que los bancos públicos se caracterizan por ser esencialmente buenos o malos. Esto es poco realista y poco útil a la hora de buscar formas de hacer frente a las crisis financieras y de la financiación climática. En su lugar, necesitamos repensar los bancos públicos como instituciones dinámicas y disputadas dentro de las esferas públicas de los Estados. Desde este punto de vista, la propiedad pública en sí misma no predetermina nada, pero sí abre un ámbito público particular de posibilidades. El cambio se hace posible y es el resultado de las fuerzas sociales que lo hacen posible, aunque dentro de los límites estructurales de la sociedad capitalista dividida por género, raza y clase social. Una teoría dinámica de los bancos públicos ofrece una alternativa teórica novedosa y una vía práctica hacia la financiación de transiciones ecológicas y justas en aras del interés público.
Banca pública colectiva para el bien común en la región nórdica
Authors: Juuti Petri S. , Juuti Riikka P. , McDonald David A.
Published: October 2024

Los bancos estatales de Finlandia, Suecia, Noruega y Dinamarca han desempeñado un papel fundamental en el financiamiento de los costos de los servicios públicos de agua en la región nórdica durante más de un siglo. Un modelo bancario mancomunado, de propiedad colectiva y operado por los gobiernos municipales y/o nacionales, ha permitido a los operadores estatales de agua obtener financiamiento a las tarifas más bajas posibles, mejorando los servicios y protegiendo su estatus público. No está exento de desafíos, incluidas las amenazas de privatización y comercialización de los operadores públicos de agua y los bancos públicos, pero este modelo nórdico tiene mucho que ofrecer a los debates globales sobre el financiamiento estatal de los servicios públicos de agua.

Uma história para a descontinuidade da matéria nos séculos XVII e XVIII
Authors: Sánchez Gabriel , Alarcón Laura , Aponte-Buitrago Ricardo , Dos Santos Pereira Letícia , Garay Garay Fredy Ramon
Published: October 2024

O entendimento da descontinuidade da matéria é basilar para a compreensão das teorias químicas, mas há muitos obstáculos para sua compreensão. Não obstante, as propostas de ensino com base na história da química para o ensino dos modelos atômicos não enfatizam a descontinuidade como uma parte importante desses modelos, nem são suficientes para compreender as origens e antecedentes históricos que sustentaram uma concepção de matéria descontínua antes do trabalho de John Dalton. Este artigo apresenta uma narrativa histórica visando analisar diferentes ideias sobre a descontinuidade da matéria surgidas nos séculos XVII e XVIII. Espera-se que tal apresentação histórica possa auxiliar pesquisadores, professores e estudantes de graduação que buscam uma leitura introdutória a esta temática.

Authors: Tomalá D. , Gutiérrez M. , Quirumbay C. , Iturralde S.
Published: October 2024

In this study, the behavior of the recovery factor during the displacement and storage phases of carbon dioxide (CO2) in an Ecuadorian reservoir was investigated by numerical simulation. Continuous injection and CO2 WAG methods were used. The methodology included field data collection, creation of a static reservoir model, configuration of the PVT model with CMG software, construction of a dynamic model in GEM-CMG based on rock-fluid properties, and evaluation of CO2 injection scenarios. After a screening analysis, the optimal scenario was identified and the performance of the recovery factor over time was studied. The results indicated that, during the 8 years of simulation, the recovery factor with continuous injection was 28%, while with the WAG method it reached 31%. It was concluded that WAG was the most efficient method. Regarding storage, it was observed that continuous injection was able to store 83% of the CO2 in the reservoir.
Mobile crawler robot for seed sowing and route planning through neuro-diffuse control
Authors: Figueroa J. , Yarad M. , Montaño M. , Gomez O. , Rovira R.
Published: October 2024

The main objective of this project is to build a mobile terrestrial robot that allows the sowing of seeds of various types of plants that are cultivated in an artisanal way. A structure based on tracked locomotion has been designed that involves the use of several sensors, DC motors, and control systems based on two Arduino boards, which together allow the mobile robot to interact with the irregular environment through which it moves. The locomotion process carried out by the seeding robot is configured through an HMI interface implemented on a touch screen, where the user chooses the type and quantity of seeds to be sown so that the robot then follows an autonomous rectilinear trajectory which is supervised and corrected utilizing a neuro-diffuse control such as ANFIS. In addition, the mobile robot has a battery feeding and charging system through solar panels, which gives it complete autonomy to carry out the work entrusted to it.
Dyeing ability of C. longa L. and T. stans (L.) Juss. Ex Kunth on unmordanted and mordanted silk and cotton fabrics
Authors: Ovonramwen O. B. , Eshiokhai G. R.
Published: October 2024

The work was on the extraction of both the C. longa rhizomes and the petals of T. stans using four different solvents (ethanol, ethyl acetate, water, and n-hexane). The dyeing potential of the C. longa and T. stans extracts was evaluated on cotton and silk fabrics without or with mordants using potash alum, phosphomolybdic acid, iron (II) sulphate, and tartaric acid at varied temperatures and tested for colour fastness properties (wash and light fastness). The pH and absorbance of the dye bath before and after dyeing were studied. However, cotton, which is cellulosic, was better dyed than silk, which is proteinous, which showed a better choice for fabrics dyeing at 80 °C; hence, it had a good colour efficiency. Iron (II) sulphate exhibited complexes in the octahedral configuration of the coordination six with CH2O- of cotton and NH3+ and COO- of silk fabric. In addition, it was also observed that the higher the dyeing temperature, the greater the dyeing intensity. The spectroscopic characterization of the extracts was determined with the help of UV-Vis and FTIR. The UV-Vis and FTIR spectral analyses revealed the chromophore, auxochrome groups, and functional groups, respectively, within the extracts. Curcumin and rutin were identified as being responsible for the dyeing of the fabric.

Published: October 2024

Abstract: This study addresses a critical issue in road safety by proposing innovative solutions to mitigate accidents caused by speeding and reckless driving, particularly in high-risk areas such as highways, hospitals, and schools. With road traffic accidents accounting for approximately 1.3 million fatalities annually, along with 20 to 50 million injuries or disabilities, the inefficacy of traditional traffic control systems is a growing concern. Factors such as poor visibility, adverse weather, and driver distractions further compromise the effectiveness of conventional signs and signals. This research introduces a "smart zebra crossing" system that integrates ultrasonic sensors and embedded LED lights to provide real-time alerts to both drivers and pedestrians, thereby enhancing visibility and safety, especially under low-light conditions. Additionally, a "smart speed breaking" system is proposed, which dynamically adjusts its height based on vehicle speed, detected through ultrasonic sensors, prompting drivers to decelerate when necessary. Both systems are linked to a central traffic management network, facilitating real-time adjustments in speed limits and providing alerts to connected vehicles. The integration of these technologies represents a significant advancement in road safety, offering an adaptive, intelligent solution for improving traffic management and reducing the risk of accidents, particularly in vulnerable zones.

Abstract: This project focuses on the innovative development of a regenerative magnetic suspension system that uses permanent magnets to capture energy from the vibrations and movements of vehicles, aiming to improve energy efficiency and sustainability within the automotive sector. Unlike conventional suspension systems that dissipate energy as heat, this design utilizes highperformance neodymium magnets and wound copper coils to convert mechanical energy into electrical energy via electromagnetic induction as the vehicle moves across varying terrains. The energy recovered through this process can potentially power auxiliary vehicle systems such as sensors, lights, and infotainment units, thereby contributing to overall vehicle efficiency. Preliminary simulations and calculations indicate a substantial potential for energy recovery, positioning the system as a cost-effective and practical solution that can be integrated into existing vehicle architectures with minimal modifications. By leveraging readily available materials, this project addresses the challenges of energy waste in conventional suspensions while promoting sustainable practices. The research not only advances regenerative technologies within the automotive industry but also paves the way for future innovations in vehicle design and broader engineering applications
