Culture Awareness: Providing Conditions To Reflect Upon The Efl Students’ Own Culture
Authors: Sosa Gladys Saavedra , Casas Daniel Antonio Arias
Published: October 2024

Este artículo presenta los resultados de un proyecto de investigación a menor escala en la relación con la importancia de la conciencia cultural de los estudiantes de inglés como lengua extranjera, con el objetivo de ofrecer las condiciones que les permita reflexionar acerca de su propia cultura durante el proceso de aprendizaje. Durante la implementación de este proyecto se evidenció que los estudiantes de nivel I de Inglés del Instituto de Idiomas de la UPTC parecían no ser conscientes de algunos aspectos culturales importantes en el aprendizaje de una lengua debido a que no tenían suficientes espacios de reflexión. Este proyecto se desarrolló bajo las características de un estudio de investigación acción en donde se diagnosticó un problema, se planeó una intervención, se ejecutó algunos talleres y finalmente se evaluó los resultados (Baskerville en French 2009). Para la recolección los siguientes instrumentos fueron empleados: cuestionarios y grabaciones en video. Los resultados mostraron que la conciencia de cultura no está solamente relacionada con identidad sino también con la disposición que los estudiantes muestran cuando aprenden una lengua en términos de valorar sus experiencias, creencias, y contextos entre otros.Palabras clave: cultura, conciencia, reflexión, conciencia de cultura, cultura de la lengua materna AbstractThis article presents the results of a miniscale research project related to the importance of the cultural awareness in the EFL students in order to provide conditions to allow students reflect upon their own culture. During the implementation of this project, it was evident that the students of abasic first level of English at the Language Institute at the UPTC seemed not to be aware of some important cultural aspects when learning a language because there is not enough exposure to reflectionenvironments. This mini-scaleproject was framed under the action research approach following a cycle of diagnosis, planning,executing and evaluating (Baskerville in French, 2009). In order to collect data the following instruments were used: questionnaires, and video recordings. The  findings revealed that cultural awareness is not only related to identity and communication but also to the dispositions that students deploy when learning a language in terms of valuing their own background, beliefs, and contexts among others.Key words: Culture, awareness, reflection, culture awareness, L1 culture.

Authors: Dueñas Macías Fredy Alonso
Published: October 2024

AbstractThis literature review aims at dealing with some issues to be considered at the momentof thinking about the incorporation of critical pedagogy in the EFL classroom. In suchway, it explores different points of view given by several authors who have been workingdeeply on this topic. Thus, it compiles and discusses the most relevant issues in relation to the definition of critical pedagogy, education as reproduction, English language and critical pedagogy, critical pedagogy into practice, the role of the teacher, and the incorporation of critical pedagogy in the classroom. Finally, critical pedagogy is tackled in this document taking into account that it is necessary to look for teaching  approaches which go against the conventional language classrooms and the traditional teaching and learning processes that do not have a transformational effect on learners.Key words: critical pedagogy, education as reproduction, role of the teacher, Englishforeign language classroom.
Refining speaking and listening skills using podcasts perfeccionando las habilidades de habla y escucha usando podcast
Authors: Prada Hernández Victor Felipe
Published: October 2024

This paper presents, the process followed in a case study research carried out at a private school in Tunja, with the tenth grade students. Podcasts were used as a tool to refine the listening and speaking skills, where the students evidenced some difficulties at the time of understanding speeches and conversations in class, and trying to talk about different themes. This research was based on some surveys and interviews to get the students’ responses that showed that despite of attending to a private institution where its core subject was English, they did not feel confident and expressed the lack of tools to develop these skills. Through the podcasts, learners approached to the development of these skills, because of the likingthey had for technology, and also because the activities, exercises, workshops and even tests were designed and adapted bearing inmind their likes, interests and needs.
Identity: Socio-Political, Sociological, Humanistic and Poststructuralist Perspectives
Authors: Salamanca González Fredy Orlando
Published: October 2024

Identity hasmultiple definitions and is related to many fields and theoreticians. It iscommonly believed that each person possesses one single and personal identity, but several perspectives have proposedmultiple dimensions for it. This article presents some dimensions about what the termidentity involves fromthe socio-political, sociological, humanistic, social and poststructuralist perspectives. Despite identity is displayed by people, is perceivable, transmittable, influenced by many factors, defining identity can get anywhere depending on the path to follow. The only certainty is that motivation, desires, preferences, ideology, words, tones, interjections, and clothing are issues related to identity.
Rethinking the Intersection Between Technology, Digital Literacies and Language Ecologies
Authors: Mora Raúl Alberto
Published: October 2024

Este artículo discute el proceso continuo de reflexividad del autor sobre las nuevas formas de describir al inglés en las ecologías del lenguaje actuales. Específicamente, el autor cuestiona si los binarios tradicionales como segunda lengua/lengua extranjera o hablantes nativos/no nativos siguen siendo viables. Por lo tanto, el autor propone una visión revisada de segundas lenguas que reconozca cómo la mediación tecnológica abre nuevos espacios para la creatividad y la apropiación en el uso de la lengua. Este artículo también incita una visión del inglés (y las segundas lenguas) que se intersecte con la tecnología y las literacidades digitales como herramienta para el acceso y la inclusión social. La combinación del inglés y estas nuevas tecnologías, si se concibe cuidadosamente, puede proveer los primeros pasos hacia sociedades más equitativas. Finalmente, el artículo presenta unas implicaciones iniciales para la pedagogía, las prácticas en literacidad y la investigación en sus apartes finales.

Authors: Parra Espinel Julie Natalie
Published: October 2024

As an attempt to describe a resilience process after a landslide through narratives, this research study aims at analyzing, interpreting and describing how Chevano tenth graders restory their resilience experience after a natural disaster in their hometown. This inquiry was carried out with students at López Quevedo School in Jericó - Boyacá, Colombia. The information was gathered through students’narratives, students’ interviews, and researcher’s field notes. Narratives made part of a pedagogical intervention to explore student’s ways of coping with tragedy, and they allow students’ voices to be expressed. It was revealed that students needed to share their stories to achieve a process ofresilience but it was important to give participants the time to start that process. Moreover, they needed to be involved in a social context they felt they made part of as well as in a routine in which they could set apart the negative thoughts and feelings of sadness from their present experiences.

Students´ Self-Image Construction Through Writing from a Social
Authors: Siachoque Cárdenas Nayibe Pilar
Published: October 2024

This qualitative case study discusses the main factors that influence self-image construction of eighth graders, through the implementation of writing tasks. Two theoretical constructs grounded this study: adolescence, and identity which breaks down into: self-image and self-esteem. This study delves into how students construct their self-image and the aspects of behavior that shape it. The study wasconducted with 34 students in a public school in Boyacá. Moreover, the instruments used to gather data were students´ artifacts, a semi-structured interview and a questionnaire. It was found that there is a dichotomy in the participants’ behavior while they are at home with their parents and when interacting with peers at school. It was also found that the behaviors that shape their self-image relate to the  way they are transitioning from children to adolescents. Students started defining themselves with more critical and mature insights.

The Role of the EU in the Justice System Reforms
Authors: Matić Bošković Marina , Kostić Jelena
Published: October 2024

The European Union plays a significant role in reforming the judicial system, both in countries aspiring to EU membership and in existing EU member states. Achieving an adequate level of judicial independence, accountability, professionalism, and efficiency is crucial for preserving the rule of law across the EU. To this end, the European Union employs various mechanisms, initiatives, and corrective measures. These are essential not only for supporting judicial reforms but also for monitoring and evaluating the implementation of the recommendations provided.The aim of this paper is to highlight the importance of the European Union’s role in supporting judicial reform in both member states and countries aspiring to EU membership. To achieve this, the authors analyze European standards relevant to the independence, impartiality, and efficiency of the judiciary, as well as various mechanisms, reports, and opinions from relevant bodies. This approach allows authors to identify not only the challenges observed but also examples of good practices that can be valuable for both member states and candidate countries seeking EU membership.
Redes sociais evangélicas e música gospel no Brasil
Authors: Bandeira Olívia
Published: October 2024

Nas últimas décadas, a utilização das mídias por igrejas evangélicas brasileiras se intensificou com a disseminação das redes sociais na internet. Viu-se também uma ampliação do mercado de bens culturais religiosos, sobretudo na área da música. Se essas múltiplas mediações comunicacionais servem aos propósitos religiosos, políticos e econômicos das igrejas, a consolidação desses mercados também apresenta desafios às autoridades dessas instituições, ao dar visibilidade a uma multiplicidade de agentes e discursos que fogem ao seu controle. Neste artigo, a partir do estudo de redes sociais de lideranças religiosas e de artistas da música gospel, discutiremos de que forma questões raciais circulam no mundo religioso evangélico a partir de suas margens. A pesquisa que deu origem a este artigo se baseia no estudo das carreiras de artistas gospel e suas atividades nas redes sociais e permite observar que as questões raciais têm adentrado as igrejas evangélicas não a partir da ação exclusiva de lideranças, mas de suas margens sem, no entanto, provocar mudanças estruturais.
20 Years of Scientific Study on Business Intelligence and Decision-Making Performance: A Bibliometric Analysis
Authors: Charkaoui Abdessamad , Jabraoui Siham
Published: October 2024

Background: Business intelligence (BI) is an area in which data analytics is applied to generate crucial information supporting business decision-making and has been a significant domain for over three decades. However, there is uncertainty regarding whether investments can effectively improve organizational outcomes.
Objective: This study aimed to provide a comprehensive overview of the knowledge generated and disseminated in previous investigations related to the intricate relationship between BI and decision-making performance (DMP) over the past 20 years.
Methods: An R-tool namely bibliometrix, which supports suggested workflow for conducting bibliometrics and includes descriptive as well as knowledge structure analysis was used on a dataset containing 1,484 English-language articles published between 2003 and 2023 and indexed in Web of Science databases.
Results: The results showed that field study has stabilized over the past three years, signaling a shift in the focus of scholars. However, only a few studies use decision theory and further investigations are required to fully understand how BI impacts DMP both inside and outside organizational boundaries.
Conclusion: Based on the results, BI studies tend to be more application-oriented and there is a need to change the emphasis from focusing only on tools to variables such as the role of effective use and competencies that might improve decision quality.
 
Keywords: Business Intelligence, Decision-Making Performance, Decision Quality, Bibliometrics, R-tool.
Diversidad y captura de CO2 del arbolado del Parque Ecológico Zazil, Chetumal, Quintana Roo
Authors: Reyes Chan Luis Enrique , Silva Poot Herlinda del Socorro , Vega Azamar Ricardo Enrique
Published: October 2024

Diferentes factores, como la rápida urbanización y el uso desmedido de combustibles fósiles para las actividades económicas que se llevan a cabo dentro de las ciudades, han contribuido al aumento de los Gases de Efecto Invernadero (GEI), siendo el CO2 uno de los principales causantes del incremento de la temperatura en la Tierra y, como consecuencia, cambios en el clima. Hoy en día, estrategias como la captura de CO2 en el arbolado de los parques públicos urbanos se han puesto en marcha dentro de las ciudades para la disminución y mitigación de los efectos de este gas atmosférico. El objetivo de este trabajo fue determinar la diversidad arbórea y cantidad de CO2 que se encuentra capturada actualmente en el Parque Ecológico Zazil de la ciudad de Chetumal, Quintana Roo, México. Para esto, se realizó un levantamiento dasonómico en una superficie de 4.5 ha, correspondientes al arbolado dentro del parque, con información de los especímenes con diámetros mayores a 7.5 cm, registrando el diámetro normal (1.30 m de la base del suelo) y la altura total. Se identificaron 71 especies y 32 familias distribuidas en 2366 individuos. También se evaluó la diversidad y riqueza mediante los índices de Margalef (D Mg) registrando un valor de 9.01, el índice de Menhinick (D Mn) presentó un valor de 1.45 y el índice de Simpson (1-D) con un valor de 0.50, lo que evidencia una alta diversidad en el parque. Además, se determinó la biomasa y, a través de la misma, se estimó el contenido de carbono aplicando un factor de conversión de 4.7 %. Estos datos se convirtieron a CO2 utilizando la constante 3.67. Los resultados arrojaron un total de 215.339 t-CO2-e/ha capturado en el arbolado del Parque Ecológico Zazil, lo cual es equiparable a cantidades capturadas reportadas en otros estudios. La información generada contribuye al diseño de parques urbanos y a la conservación de su arbolado como estrategias de mitigación, mediante la captura de carbono a nivel ciudad.
Del modelo estatista al financiero en la producción de vivienda en la Zona Metropolitana de la Ciudad de México
Authors: Luna Moreno Francisco Javier
Published: October 2024

Este trabajo analiza las diversas modalidades de producción de vivienda en la Zona Metropolitana de la Ciudad de México (ZMCM), enfocándose en los arreglos resultantes de la interacción entre actores públicos y privados, políticas habitacionales y formas de producción del sector. Se analizan los cambios en los roles del Estado, así como del sector inmobiliario y financiero, junto con las diferentes lógicas de producción habitacional. Esto se realiza a través de una revisión sistemática de la literatura especializada y de la cuantificación de la producción de vivienda entre 2000 y 2022, lo cual ha permitido enriquecer la discusión sobre la financiarización del sector habitacional en la ZMCM. La importancia de considerar el sector habitacional dentro de su contexto histórico-geográfico reside en la identificación de los elementos que lo estructuran, así como en los efectos socioterritoriales y las experiencias que de ellos se derivan. Como conclusión, se señalan tres modelos de producción: el primero, caracterizado por una fuerte participación del Estado; el segundo, relacionado con la emergencia de los mercados inmobiliarios de vivienda; y el tercero, que destaca por la complejidad de las (inter)relaciones entre el Estado, los mercados inmobiliarios y las instituciones financieras. Este último se manifiesta en nuevos arreglos institucionales y proyectos de gran escala, tanto en las periferias como en las zonas centrales urbanas. Los resultados contribuyen a entender los procesos y mecanismos que han transformado la vivienda de una necesidad básica a una mercancía y un objeto de inversión.

Pakistan Quest for security An Analysis of Internal and External Security
Authors: Begum Asma , Umer Maria
Published: October 2024

Many times, people think of terrorism as a premeditated, harsh response to perceived injustices. Unfortunately, reports on the repercussions of terrorism frequently lack a clear understanding of the psychological and societal reasons that underlie these kinds of acts. Pakistan has been at the forefront of both the global counterterrorism effort and the experience of terrorism since the events of 9/11. This essay examines the security issues that Pakistan faces as a result of terrorism, which feeds a vicious cycle of radicalization. Pakistan is suffering greatly as a result of the aftermath of terrorism, which has affected its political, social, economic, and physical infrastructure. Terrorism has cost the nation dearly on the social, economic, and human fronts. Despite playing a significant role in the global campaign against terrorism, Pakistan has received unjust labels as a financier of global terrorism. Pakistani terrorism is a complicated problem shaped by many variables, with psychological aspects being one of the most important ones. Since 9/11, countries with a majority of Muslims, especially Pakistan, have felt emotionally threatened by the term "terrorism," frequently connecting it to crimes committed by extreme groups wrongly classified as Muslim
Development of an inertial profiler specification for airfield pavement construction
Authors: Ward Andrew , Rutland Craig
Published: October 2024

The US Army Engineer Research and Development Center (ERDC) developed a test method and specification for measuring the smoothness of newly constructed airfield pavements using the inertial profiler. The limitations inherent in the currently accepted measurement system, the California-type profilograph, are detailed in this report. The effort detailed herein draws attention not only to the superior repeatability of the inertial profiler but also to the device’s ability to report true surface profile more accurately than the California-type profilograph. Correlations were drawn between the two devices with high (greater than 0.8) goodness-of-fit, and recommendations were made pertaining to the use of inertial profilers in place of California-type profilographs. These recommendations were not only founded on the data collected and analyzed in this effort but are also consistent with the current state of practice for other federal agencies, such as the Federal Aviation Administration and the Federal Highway Administration.

Published: October 2024

The technology of cellular communication for the fifth generation, 5G, is used in several applications that require high speed data, broadband, and low latency, such as Industry 4.0, wireless sensor networks, high-speed mobile communications, smart cities, smart grids, and other emergent technologies. Antennas for wireless wearable devices are required to have a compact structure and withstand temperature variations and mechanical tensions. The use of bioinspired plant shapes in the printed circuit board (PCB) antenna technology enables the development of compact devices, featuring omnidirectional radiation pattern, and wideband. This work introduces a type of PCB antenna, flexible and wearable, bioinspired on Neem plant-shapes (Azadirachta indica), applied to 5G band at 3.5 GHz, operating in the range of 3.3 GHz to 3.6 GHz. The antennas are built using polyamide as a dielectricin polyamide dielectric, a flexible material resistant to high temperatures and mechanical tensions, with the plant shape generated by the Gielis formula. The wearable bioinspired antennas feature a wideband characteristic, with measured bandwidth of over 500 MHz, a compact structure measuring 23.36 mm in length and 17.52 mm in width, an omnidirectional radiation pattern, a half power beamwidth of 84 degrees, a maximum gain of 2.03 dBi, and coverage of the 5G band at 3.5 GHz. Simulation results show that displacement of the ground plane affects the resonance frequency, with optimal results at a distance of 1 mm.

Authors: Akhil N. , kumar B. Narendra , Sai M. Manikanta , Bhargav E. Shiva , Pavan T. Sai
Published: October 2024

Concrete, the building material is becoming more valuable due to its high cost. To minimize its worth, new building industry improvements use extra elements such as marble powder. This partial replacement decreases expenses, saves energy, and protects the environment. In order to overcome the problem of dolomite waste in developing nations like India, the current research investigates the usage of dolomite powder as a cement substitute in concrete. The purpose of the study is to determine how concrete workability, compressive strength, and flexural strength are affected when dolomite powder replaces some of the cement in the mixture. Additionally, to promote a more sustainable approach in the building industry, the research intends to safeguard natural raw resources such as sand and stone aggregates. The study develops M30 grade concrete and examines its physical characteristics, such as workability, compressive strength, and flexural strength at various percentages like 5%,10% and 15% and this research investigated the microstructural analysis of dolomite powder by conducting scanning electron microscopy and XRD analysis. Cube examples of M30 grade concrete mix were casted for research purposes. This research aims to use dolomite waste in concrete to reduce building costs and promote environmental sustainability. Protecting natural resources, such as stone aggregates and sand, is crucial. As a result, the modern building sector has adopted the notion of sustainability, and it was found that the optimum content of dolomite powder was 10% where better results are obtained.
Elevated ENSO extremes are reducing tropical forest invertebrate diversity and function
Authors: Ashton Louise , Sharp Adam , Boyle Michael , Bonebrake Timothy , Guo Yirong , Kitching Roger , Stork Nigel , Zeng Xiaoyi
Published: October 2024

The conservation status of invertebrates globally is uncertain1–5. In particular, information from primary tropical forests is limited3–5, and yet invertebrates are responsible for crucial processes in the ecosystem6,7 as well as being an essential food source for many vertebrates. There is currently significant debate as to whether invertebrate biodiversity is in long-term decline due to climate change4,8 or changing naturally alongside weather9,10. We demonstrate that both are true in primary tropical forests: intensified El Niño Southern Oscillation cycles under climate change11 are disrupting natural fluctuations in invertebrate diversity. We generalized species richness shifts for nine invertebrate Orders from 33 time series spanning primary forests in the Americas, Africa and Asia. The most speciose Orders were all in long-term decline, while others showed more violent fluctuations in diversity with ENSO extremes over time. El Niño appeared to drive strongest declines in those Orders which naturally increase in diversity during La Niña. In addition, we found our diversity generalizations correlated with tropical-scale reductions in rates of invertebrate driven leaf litter decomposition during El Niño events and steep leaf herbivory declines across 76 decomposition/herbivory studies. Our analyses suggest that increasingly fluctuating climate extremes immediately threaten primary forest invertebrates, their ecological functions and hence the survival of these forests. Understanding the mechanisms behind this novel threat is paramount, as is expanding future long-term monitoring of tropical invertebrate biodiversity.
Study on the Biological Changes Related to NF-κB and Therapeutic Effects of Phellodendrine Intervention in Noncompressive Lumbar Disc Herniation
Authors: Tan Panlin , Mei Jianbing , Wang Dong
Published: October 2024

Objective
To explore the therapeutic effects of phellodendrine on noncompressive lumbar disc herniation (NCLDH).
Methods
A rat model of NCLDH was established via autologous caudal nucleus pulposus transplantation. Behavioral observations and neurological function scoring were conducted in rats, and the serum levels of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) were measured via enzyme-linked immunosorbent assay (ELISA). Real-time quantitative polymerase chain reaction (RT‒qPCR) was used to detect the expression of NF-κB p65 mRNA in L5 nerve roots and surrounding tissues. Western blotting (WB) was used to assess the protein expression of NF-κB p65 and TNF-α. Immunofluorescence (IF) and immunohistochemical (IHC) analyses were performed to investigate the distribution and expression of the NF-κB p65 protein in the L5 nerve and its surrounding tissues.
Results
In this animal study, phellodendrine was found to downregulate the expression of p65 mRNA, decrease the release of inflammatory factors, and alleviate motor dysfunction caused by LDH. Therefore, the phellodendrine technique has potential value for the treatment of noncompressive LDH.

Antibody-mediated co-delivery of programmable drug combinations
Authors: Meng Xun , Sun Wenlong , Weng Weining , Shi Jing , Ma Boyang , DeMarco Kelly , Gui Fu , Jin Rui , Ruscetti Marcus , Jia Li , Hu Wenhao , Meng Tao
Published: October 2024

Drug combinations often fail in clinic due to poor disease site tropism and additive toxicities1,2. Targeted delivery by antibody-drug conjugates (ADCs) reduces toxicity for single chemotherapeutic payloads3. Multi-payload ADCs for combination therapy are limited to two chemotherapeutics at fixed ratio due to a lack of efficient linker-payload chemistry and an incomplete understanding of payload combination synergy and toxicity4. We previously developed T1000-payload chemistry for higher ADC stability5-7. Although combinations of synergistic drug payloads delivered individually by T1000-ADCs manifest ratiometric synergy, they also result in additive toxicities. Here we introduce a programmable drug co-delivery architecture called Synergistic Payload-Antibody Ratiometric Conjugate (SPARC) featuring higher efficacy without proportionally increased toxicity. SPARC is based on multi-T1000-payload (MTP) chemistry designed with enhanced steric shielding for less payload release than T1000-ADCs. MTPs are synthesized by orthogonally linking single T1000-payloads by azide–alkyne click chemistry. Site-specific antibody-MTP conjugations8 produce homogenous, stable SPARCs capable of hosting 2-6 drugs from diverse classes, with a tunable payload ratio from 1 to 10 and payload number as high as 30. Comparing to combinations of single-payload ADCs/free drugs, SPARCs display a more precise pharmacological discrimination in vivo-lower off-target additive toxicity due to reduced payload release but higher efficacy in targeted cells by synergistic/additive interactions among pharmacokinetically synchronized payloads. SPARCs combining Topoisomerase I with DNA Damage Response or cell cycle inhibitors display expanded therapeutic window in drug-resistant prostate and breast cancer models. SPARC provides a conceptual and methodological framework for combination therapy discovery and clinical translation. Payload-agnostic SPARC chemistry may resurrect generation of abandoned drugs by repurposing them as deliverable payloads.

Monitoring and tracking of cell motion is a key component for understanding disease mechanisms and evaluating the effects of treatments. Time-lapse optical microscopy has been commonly employed for studying cell cycle phases. However, usual manual cell tracking is very time consuming and has poor reproducibility. Automated cell tracking techniques are challenged by variability of cell region intensity distributions and resolution limitations. In this work, we introduce a comprehensive cell segmentation and tracking methodology. A key contribution of this work is that it employs multi-scale space-time interest point detection and characterization for automatic scale selection and cell segmentation. Another contribution is the use of a neural network with class prototype balancing for detection of cell regions. This work also offers a structured mathematical framework that uses graphs for track generation and cell event detection. We evaluated cell segmentation, detection, and tracking performance of our method on time-lapse sequences of the Cell Tracking Challenge (CTC). We also compared our technique to top performing techniques from CTC. Performance evaluation results indicate that the proposed methodology is competitive with these techniques, and that it generalizes very well to diverse cell types and sizes, and multiple imaging techniques.

Myopia is a global pandemic, with significant adverse effects on visual health, it is essential to excavate a more comprehensive and inclusive myopia defence that can address the lack of myopia defences due to age, refractive error and astigmatism range. In this study, the multifocal rigid gas-permeable contact lens (MF-RGPCL) was employed as a myopic intervention, the efficacy of MF-RGPCL were observed by the changes in axial length (AL) and best-corrected visual acuity (BCVA) , and the safety was evaluated by monitoring the changes in corneal endothelial cells. Additionally, analyse the subjects' ocular parameters, genetic characteristics, lens’ fit, growth and development and which affect the development of AL in the MF-RGPCL group. After one year, the axial growth of the MF-RGPCL group was significantly slower than that of the SVL group. Similarly, the BCVA of the MF-RGPCL group was significantly better than that of the SVL group. And the AL progression in the MF-RGPCL group was significantly correlated with onset age of myopia, parental myopia, lens decentration, pupil distance, and corneal curvature. No significant alterations were observed in the corneal endothelial cells. MF-RGPCL has been demonstrated to provide effective myopia control and good safety, and can be used as an alternative for myopia defence in adolescents.

Published: October 2024

Rechargeable implantable generators (r-IPGs) have been used in spinal cord stimulation (SCS) for chronic pain treatment since 2004, offering longer lifespans compared to traditional devices. Closed-loop SCS (CL-SCS) systems, which use neurobiological feedback to regulate spinal cord activation, rely on r-IPGs for power. However, there is limited data on the long-term performance of these devices, including the ease of recharging and potential interruptions during the process. To address these gaps, a study was conducted using a 48-item questionnaire distributed to chronic pain patients with CL-SCS devices. Results from 8 patients indicated that the recharging process was generally considered very easy, with an average charge burden of just over three hours per week. Most patients felt confident managing their neurostimulators, though one patient reported interruptions during recharging. These findings suggest that while CL-SCS systems require more effort compared to conventional devices, they offer greater comfort and fewer issues related to recharging and interruption. This early data highlights the need for larger studies comparing CL-SCS with conventional SCS systems to further evaluate patient convenience and device performance.

Background
Adolescence is a critical developmental stage characterized by emotional challenges and an increased vulnerability to depressive symptoms (DS). While poor sleep quality (PSQ) is known to correlate with DS, the roles of coping strategies (CS) and self-efficacy (SE) in this relationship remain underexplored.This study investigates the relationships between sleep quality (SQ), CS, SE and DS among adolescents, emphasizing the mediating role of CS and the moderating role of SE in the SQ-DS relationship.
Methods
Utilizing a cross-sectional design, data were collected from 1,132 junior high school students in China between January and June 2023.Participants completed self-report questionnaires assessing the Self-Rating Depression Scale (SDS), the Pittsburgh Sleep Quality Index (PSQI), the Simplified Coping Style Questionnaire (SCSQ), and the General Self-Efficacy Scale (GSES). Descriptive statistics, correlation analysis, regression analysis, and mediation-moderation analysis using PROCESS were conducted to examine variable relationships.
Results
The findings revealed a significant positive relationship between PSQI and SDS (Beta = 0.350, p < 0.001), indicating that PSQ is associated with higher levels of DS. CS acted as a mediator; specifically, positive coping (SCSQ.AR) negatively predicted SDS (Beta = -0.432, p < 0.001), whereas negative coping (SCSQ.NC) positively predicted SDS (Beta = 0.270, p < 0.001). GSES did not significantly moderate the direct relationship between PSQI and SDS (B = -0.0076, p = 0.5437), but it partially moderated the indirect effects through negative coping. Adolescents with lower SE were more prone to adopt negative coping strategies (NCS), which in turn exacerbated their DS.
Conclusion
PSQ is significantly associated with increased DS in adolescents, with NCS intensifying this relationship, especially among those with lower SE. Although enhancing SE alone may not significantly influence the direct impact of PSQ on DS, interventions that promote positive coping strategies (PCS) and reduce NCS, combined with efforts to enhance SE, could effectively alleviate DS. Future research should adopt a longitudinal approach to further elucidate these relationships and inform targeted mental health interventions for adolescents.

Deep drawing technology is widely used in industrial production. With the continuous improvement of industrial technology and the increasing demands of people's lives, more and more process products have put forward higher requirements for deep drawing forming accuracy. In order to improve the accuracy of deep drawing, it is essential to study the springback of deep drawing. Electro-permanent magnet technology can provide a green and environmentally friendly way to apply blankholder force in deep drawing processes. During one deep drawing process, it only needs to apply two pulse currents during magnetization and demagnetization. This article studies how to achieve the goal of predicting the springback of deep drawing using electro-permanent magnet technology to provide blank holder force through finite element analysis and data processing. The feed rate of the punch during the deep drawing process can be calculated based on the required product drawing height, and the forming accuracy can be controlled within the error range of 0.1mm. Therefore, it is feasible to achieve low-cost, high-precision forming of deep-drawn components with flanges.
