Acts of prosecutorial response used in the supervision of the investigation
Authors: Morozov Kirill Olegovich
Published: October 2024

The subject of the study is the acts of prosecutorial response in the supervision of the legality of the preliminary investigation in the form of an inquiry. The purpose of the study is to analyze the measures of the prosecutor's response used by the prosecutor in overseeing the legality of the investigation, the opinions of scientists and practitioners on the issues under consideration and to propose their own ways to solve the identified problems. To achieve this goal, the author of the study analyzes the reasons for the increased attention to the procedural activities of interrogators. The author pays special attention to the acts of prosecutorial response to illegal actions of supervised subjects. In the course of his research, the author uses dialectical, logical, systemic, functional and formal legal methods. As a result of the conducted research, the author comes to the conclusion that the inquiry was introduced by the federal legislator as a simplified form of crime investigation. The requirements for interrogators allow for the appointment of persons who do not have higher legal education, which, together with the general low professional training of employees, is a determinant factor in the admission of violations. Direct managers often do not formally respond to violations committed by the investigator, and therefore the active participation of the supervising prosecutor remains the only guarantor of legality. The supervising prosecutor has a range of acts of prosecutorial response: from mild to more severe, which allows a flexible approach to the choice of ways to respond to violations. The author of the study proposed to consolidate the right of an inquirer to appeal, with the consent of his supervisor, to a higher prosecutor with a complaint about the demands made to him.

THE USE PICCO TECHNOLOGY FOR ASSESSMENT THE FUNCTIONAL STATE OF THE HEART AND SYSTEMIC GEODYNAMICS DURING ORTHOTOPIC HEART TRANSPLANTATION
Authors: Goncharenko M.М. , Loskutov O.А.
Published: October 2024

Summary. Approximately 5000 heart transplants are performed annually in the world. According to the American College of Cardiology/American Heart Association/ Heart Failure Society of America (ACC/AHA/HFSA) and the European Society of Cardiology (ESC), there are currently more people on the waiting list for heart transplants than there are donor organs available. The Ukrainian National Waiting List of the Unified State Transplantation Information System contains more than 2,000 patients, of whom about 500 need a heart transplant.
Objective. The aim was to evaluate the effectiveness of haemodynamic monitoring using a continuous analysis system for measuring pulse waveform and transpulmonary thermodilution and its impact on orthotopic heart transplantation.
Materials and methods. The work is based on the results of 30 recipients diagnosed with dilated cardiomyopathy who underwent orthotopic heart transplantation. The average age of the recipients was 41.4±3.2 years. There were 90 % of male recipients and 10 % of female recipients. All recipients were diagnosed with dilated cardiomyopathy with reduced ejection fraction with an average of 18 ± 4.4 %. All patients underwent heart transplantation using PiCCO hemodynamic monitoring, which assessed the optimality of fluid, inotropic and vasopressor therapy with analysis of changes in the functional state of systemic hemodynamic (blood pressure, heart rate, central venous pressure, cardiac index, cardiac output, global end-diastolic volume index, extravascular lung water index, systemic vascular resistance and global ejection fraction) at the time of donor heart inclusion in the recipient’s circulation
Results. It was found that all patients had a reduced ejection fraction. In 100% of patients undergoing orthotopic heart transplantation, PiCCO monitoring was used, which showed cardiac dysfunction with a reduced cardiac index of 1.90 ± 0.24 l/min/m on average, global end-diastolic blood volume index was 571 ± 163.7 ml/m2 and was reduced, reflecting a decrease in preload. While the extravascular water index in the lungs averaged 9.2 ± 1.41 ml/kg of body weight and was increased, indicating possible pulmonary oedema at the beginning of surgery.
Conclusions. PiCCO monitoring allows real-time diagnosis of functional changes in the myocardium, differentiation of major circulatory disorders in patients with involvement of vital organs and systems, including breathing (gas exchange), classification of haemodynamic disorders and timely correction. During the study, PiCCO monitoring revealed an improvement in extravascular lung water in 95 % of patients by the end of CPR, which made it possible to adequately treat these disorders and prevent pulmonary oedema, provide adequate correction with inotropic support and balance postload with the systemic vascular resistance index and improve the cardiac index by 99.1 %.
PREOPERATIVE ANXIETY – THE FORCE OF GRAVITY OR THE ARCHIMEDEAN FORCE IN THE RESERVOIR OF THE DISEASE
Authors: LISUN Y , HULIAS D. , POLYUKHOVICH L.
Published: October 2024

Introduction. Hans Selye termed the phenomenon of the nonspecific reaction of the organism to various stimulating influences as the general adaptation syndrome, in which he distinguished three stages: alarm, resistance (adaptation), and exhaustion. In the first stage, the organism encounters certain environmental stimulating factors and attempts to adapt to them. The second stage involves adaptation to new processes. However, if the stressor continues to act for an extended period, hormonal resources are depleted (the third stage), disrupting adaptive systems. This results in the process taking on a pathological nature and may culminate in illness or death.
Objective of the study. Based on the analysis of literature data demonstrate the relevance of determining the level of anxiety in the practice of an anesthesiologist.
AUTOMATION OF PAIN MANAGEMENT SERVICES – AN OPTION FOR SOLVING COMPLEX ISSUES
Authors: KUCHYN IU.L. , HOROSHKO V.R. , KUZNETSOV A.D , SLOBODIANIUK A.T
Published: October 2024

High-quality and accurate monitoring of the dynamics of pain treatment, selection and correction of medications, prediction of long-term results and improvement of a scientifically based approach to pain treatment necessitate the automation of pain treatment services in medical institutions. One of the ideas for such automation is to create a mobile application – software to collect the necessary data on diagnosis, prescription of medications, the possibility of further scientific analysis of the results and optimization of existing approaches to pain treatment at the state level.
Objective. Improve pain diagnosis and treatment outcomes.
Results. It was found that 384 (96 %) of the patients were male. Of these, 240 (60 %) were active military personnel, 148 (37 %) were veterans, and 12 (3 %) were civilians. At the time of treatment, 332 (83 %) patients were in hospital, 40 (10 %) were at home, 16 (4 %) were in a military unit, 10 (2.5 %) were in a rehabilitation centre, and 2 (0.5 %) did not provide their location. 320 (80 %) patients were diagnosed with chronic pain, as they had a history of pain ≥ 3 months. The average pain intensity on the numerical pain rating scale was 6 (3-9) points, and the DN4 data was 5 (4-6) points. The most frequent complaints from DN4 were «tingling» and «electric shock» sensations, reported in 288 (72 %) and 272 (68 %) cases, respectively. In addition, 344 (86 %) patients complained of sleep disturbances. The average age of the patients was 35 (22-48) years.
Conclusion. In Ukraine, this is the first assessment of patients using a mobile application for pain management. Such a tool allows us to help patients with pain at all stages of treatment, regardless of their location. Particular attention should be paid to the prospect of using this approach to diagnose and treat pain in wounded, as such patients will primarily seek treatment from their family doctor after inpatient treatment and rehabilitation, who should have the option of engaging pain management experts.

Clarification of Microvibration Nature Measured by Vibraimage Technology. Part 2
Authors: А.А. Косенков
Published: October 2024

В пилотном исследовании проведено сравнение значений параметров виброизображения головы и рук с целью уточнения природы колебаний, измеряемых посредством технологии виброизображения (ВИ). Традиционно в технологии ВИ анализируются колебания головы, руки были выбраны для сравнения, исходя из того, что они в наибольшей степени представлены на карте областей коры головного мозга, ответственных за регуляцию движений и ряда других факторов. Учитывая огромную роль зрительного и вестибулярного анализаторов, а также шейных рефлексов в постуральном контроле, автор предположил, что параметры ВИ головы и рук кардинально отличаются. Данная гипотеза не была подтверждена результатами исследования, которые показали, что амплитудно-частотные характеристики колебаний головы и рук во многом похожи. По-видимому, сходство параметров ВИ, полученных в ходе анализа колебаний головы и рук, объясняется тем, что сложнейшая система постурального контроля, которая включает в себя вестибулярную, зрительную и соматосенсорную системы, оказывает координирующее влияние на весь опорно-двигательный аппарат, участвующий в достижении и поддержании равновесия и ориентации в пространстве. При этом сами колебания, которые можно отнести к физиологическому тремору, являются следствием (частью или побочным эффектом) этих регулирующих воздействий.

In the study, the values of vibraimage parameters of head and hand were compared in order to clarify the nature of vibrations measured using vibraimage (VI) technology. Traditionally VI technology analyzed head vibrations; the hands were chosen for comparison based on the fact that they are most represented on the map of the areas of the cerebral cortex responsible for the regulation of movements and a number of other factors. Considering the huge role of the visual and vestibular analyzers, as well as cervical reflexes in postural control, suggested that the VI parameters of the head and hands are radically different. This hypothesis was not confirmed by the results of the study, which showed that the amplitude-frequency characteristics of the head and hands vibration are similar. Apparently, the similarity of VI parameters obtained during the analysis of head and hands vibration is explained by the fact that the complex system of postural control, which includes the vestibular, visual and somatosensory systems, has a coordinating influence on the entire musculoskeletal system involved in achieving and maintaining balance and orientation in space. Moreover, the microvibration themselves, which can be attributed to physiological tremor, are a consequence (сomponent or side effect) of these regulatory influences.
An Entropy-Based Composite Indicator for Evaluating the Effectiveness of Recommender System Algorithms
Authors: R.S. Kulshin , A.A. Sidorov
Published: October 2024

The problem of forming a composite indicator for evaluating the effectiveness of recommender system algorithms is considered. A novel composite indicator is proposed by combining individual metrics using the entropy method. The testing base of this study consists of 12 algorithms (on the one hand) and 3 datasets (on the other). For each algorithm–dataset combination, we calculate partial criteria used in evaluating recommender systems. According to the results presented below, the composite indicator is an effective tool for evaluating the performance of recommender system algorithms. As is shown, the performance of the algorithms varies depending on the size and other basic characteristics of a particular dataset. This indicator can be used to develop more efficient algorithms and their ensembles as well as to optimize hyperparameters and improve the quality of recommendations.

Accelerating Molecular Dynamics Simulations with Quantum Accuracy by Hierarchical Classification
Authors: Dullinger Philipp , Futterer Joshua , Kappel Niklas , Wenzel Wolfgang
Published: October 2024

There has been substantial interest in the development of machine learning methods to compute the electronic structure of molecular systems with quantum accuracy with significantly reduced cost. However, due to the numerical complexity of high dimensional embeddings of the molecular information, these methods are still far more costly than traditional molecular-dynamics simulations. Here we demonstrate that a three-layer partitioning strategy of the molecular ensemble, accompanied by system-specific training of inter- and intra-molecular interactions, can accelerate reactive ML-based simulations. At the example of hydrogen-transfer reactions of hydronium in aqueous solution, we find an acceleration of three-orders of magnitude in comparison to the underlying ML model without significant loss of accuracy. This finding paves the way to enable the use of efficient ML models in large-scale molecular dynamics simulations that are applicable to problems of current interest.
Assessing the feasibility of using a data-driven corrosion rate model for optimizing dosages of corrosion inhibitors

Published: October 2024

Optimizing dosages of corrosion inhibitors requires experimental data gathered from time-consuming methods. The current study examines the feasibility of optimizing inhibitor dosages using a model trained for predicting corrosion rates more easily measured using linear polarization resistance in a full-scale cooling water system. A comprehensive study on variable selection showed that linearly correlated variables are necessary to predict corrosion trends. The Sobol sensitivity of inhibitors is trivialized by variables linearly correlated to the corrosion rate. The study highlights the importance of achieving high model prediction accuracy and high Sobol sensitivity of inhibitors to the corrosion rate, for using the model for inhibitor dosage optimization.
DNA scission of non-His-containing ATCUN-like peptides

Published: October 2024

Metallopeptides display interesting candidates for drug design from anti-cancer reagents to antimicrobials. We report the ability of non-His containing metallopeptides to perform scission of plasmid DNA exhibiting antibiotic resistance. The peptides Ac-Dap β Ala His PEG4 with an Amino-Terminal Cu(II) and Ni(II) binding (ATCUN) motif and two mutants, in which His is substituted by Ala and Asp, form complexes with Cu(II) and Ni(II) in a pH-dependent manner attributed to metal coordination. The His- and Asp-containing peptides show specificity to AT-rich DNA regions. Previously, DNA scission was only associated with His-containing ATCUN peptides of other molecular structures. Results from fluorescence displacement of Hoechst 33258 and ethidium bromide show that all three peptides bind to the DNA minor groove and this binding is enhanced in the presence of the bivalent metal ions. Molecular dynamics simulations with a DNA dodecanucleotide d(CGCGAATTCGCG) support the minor groove binding and preference for AT-rich sites for the His and Asp-containing peptides.
Electronic Structures of Late versus Early Transition Metal Imido Complexes from 15N NMR Signatures
Authors: Kakiuchi Yuya , Copéret Christophe
Published: October 2024

Imido ligand is a ubiquitous motif in organometallic chemistry, serving roles spanning from ancillary ligands to reactive sites. The nature of M=N bond is highly depended on the metal centres and their d-electron configuration, with late transition metal (TM) imido complexes exhibiting contrasting features when compared to their early TM analogues. Envisioning to uncover general electronic descriptor for the nature of imido ligands, we computationally investigate the solid-state 15N NMR signatures of late TM imido complexes with various central metals, geometries and d-electron counts, and compare them against these of the corresponding early TM systems. The spectroscopic signatures are mostly driven by the presence of filled, π-symmetry orbitals in late TM imido complexes, suggesting the development of high-lying π(M=N) and low-lying σ/σ*(M=N) orbitals. This contrasts with what is observed for the reported early TM systems, for which high-lying σ-type orbitals determine the NMR signature. Noteworthily, Ni- and Pd-imido complexes with d10 configurations exhibit highly asymmetric nitrogen-15 NMR signature with extremely deshielded principal components, because of the presence of filled, high-lying antibonding π*(M=N) orbitals, consistent with their high reactivity. The sensitive response of 15N NMR signature to the nature of metal sites further highlights that chemical shift is a useful reactivity descriptor.

Published: October 2024

Designing the architecture of donor−acceptor (D−A) pairs is an effective strategy to tailor the electronic structure of conjugated macrocycles for optoelectronic devices. Herein, we present the synthesis of three D−A nanohoops NDI-[n]CPP (n=7, 8, 9) containing naphthalene diimide (NDI) unit as an acceptor and [n]cycloparaphenylenes ([n]CPPs) moieties as donors. The D−A characteristics of NDI-[7~9]CPPs were substantiated through absorption and fluorescence spectroscopic studies, electrochemical investigations and computational analysis. The device investigations demonstrated that the D-A nanohoops NDI-[7~9]CPPs can serve as the photoconductive layer and demonstrate a significant generation of photocurrent with fast response upon exposure to light. The magnitude of photocurrent shows highly dependence on the size of their rings, with an increasing trendency as the ring size decreases. The generation of photocurrent in free acceptor-based CPP has rarely been reported in the previous literatures. Significantly, the C60 complexes of NDI-[7~9]CPPs exhibited a marked enhancement in photocurrent under identical conditions, in particular, the photocurrent of C60NDI-[7]CPP is ca 3.5 times greater than that of NDI-[7]CPP alone. Furthermore, the potential applications of NDI-[7~9]CPPs in electron- and hole-transport devices have been also explored, revealing the clear evidence of their bipolar behavior as an active charge transport layer.
Ultrafine particles and late-life cognitive function: Influence of stationary mobile monitoring design on health inferences
Authors: Blanco Magali , Szpiro Adam , Crane Paul , Sheppard Lianne
Published: October 2024

Growing evidence links ultrafine particles (UFP) to neurotoxicity, but human studies remain limited. Various mobile monitoring approaches have been used to collect repeated short-term air pollution samples and develop human exposure models. However, whether design choices impact epidemiologic inferences, including for UFP and cognitive function, remains unclear. We evaluated the adjusted association between UFP number concentration (PNC) and late-life cognitive function (Cognitive Abilities Screening Instrument – Item Response Theory [CASI-IRT]) in the Adult Changes in Thought cohort (N=5,283) by leveraging an extensive roadside mobile monitoring campaign specifically designed for epidemiologic application. To assess the impact of common, reduced monitoring approaches on this association, we repeatedly subsampled UFP measures from the extensive campaign, developed exposure models, and evaluated the degree to which associations were impacted. In a reduced adjustment model, the mean baseline CASI-IRT score decreased by 0.020 (95% CI: -0.036, -0.004) per 1,900 pt/cm³ increase in PNC. Associations were consistent across most sampling designs, including fewer visits (median point estimate -0.019, IQR: -0.022, -0.016), fewer seasons (-0.019, IQR: -0.021, -0.016), and unbalanced sampling (-0.018, IQR: -0.022, -0.016), with very unbalanced designs yielding more variable estimates. In the primary adjustment model, the CASI-IRT score increased by 0.002 (95% CI: -0.016, 0.020), with similar estimates across fewer visits (0.002, IQR: -0.001, 0.004), fewer seasons (0.000, IQR: -0.001, 0.003), and unbalanced sampling (0.001, IQR: -0.001, 0.004). Rush hour designs were more similar (0.002, IQR: 0.000, 0.003) than business hour designs (0.006, IQR: 0.005, 0.007), but the opposite was true when temporal adjustments were applied (rush: -0.003, IQR: -0.005, -0.001; business: 0.002, IQR: 0.001, 0.004). We observed similar trends in sensitivity and secondary analyses. We found no link between UFP exposures and late-life cognition. While various monitoring approaches may be used to capture epidemiologic inferences, extending beyond weekday business and rush hours is likely important.
Accessing Azetidines via Magnesium-Mediated Nitrogen Atom Transfer from Iminoiodinane to Donor-Acceptor Cyclopropanes
Authors: Bansode Ajay , Yin Lifeng , Deng Ning , Afrasi Mahmoud , Zhu Yiyi , Parasram Marvin
Published: October 2024

Herein, we report a Lewis acid-mediated ring expansion of donor-acceptor cyclopropanes (DACs) to substituted azetidines via nucleophilic nitrogen atom transfer from readily accessible iminoiodinane. This protocol operates under mild, transition-metal-free conditions, and showcases excellent chemoselectivity, along with broad functional group tolerance. We report for the first time that unactivated donor-acceptor cyclopropanes can undergo ring expansion leading to aliphatic azetidines without relying on external oxidants or precious transition-metal catalysts. Mechanistically, the coordination of a Magnesium (Mg)-Lewis acid to the DAC promotes nucleophilic ring opening with a putative Mg-amide species generated from the iminoiodinane under the reaction conditions to furnish the azetidine products.

A comprehensive search was conducted across Scopus and PubMed databases in February 2024. Extracted articles were screened using Hubmeta software, with duplicates and non-relevant studies excluded. The final selection, comprising 24 articles, focused on survival predictions through ML techniques. These studies, published mostly post-2019, included datasets ranging from 75 to 9,462 cervical cancer patients and up to 91,294 squamous cell samples. The most commonly applied ML models were Random Forest (RF), Neural Networks (NN), Support Vector Machines (SVM), Ensemble and Hybrid Learning, and Deep Learning (DL). The area under the curve (AUC) for these models ranged from 0.84 to 0.9875, demonstrating their strong predictive capabilities. Clinical patient records were the primary data source. Meta-analysis was performed on the extracted data using GraphPad Prism for descriptive statistics and One-Way ANOVA. No significant differences were found between group means, as evidenced by an R-squared value of 0.1459. This result indicates that the independent variable (year of study) explained only 14.59% of the variance in ML model performance. The study found that the use of ML models has increased over time, particularly with Convolutional Neural Networks (CNNs) such as the ResNet50 model, which demonstrated superior accuracy metrics, including over 90% accuracy for the ResNet152 variant. These findings suggest that integrating multi-dimensional data with ML models holds significant potential for improving survival predictions in cervical cancer patients. Future research is recommended to develop tailored ML algorithms with even higher predictive accuracy for cervical cancer survival.

Colombia acogió las metas establecidas en la Agenda 2030 enfocada a alcanzar los Objetivos de Desarrollo Sostenible - ODS planteados por la Organización de las Naciones Unidas – ONU y propuso la Estrategia 2050 – E2050 direccionada a la descarbonización del país; por tal razón es fundamental que cada grupo de interes tome conciencia y acciones por el clima, en especial el sector industrial por ser una de las principales fuentes de emisión de gases de efecto invernadero. Este trabajo, busca contribuir a través de una herramienta que permita medir el estado actual del nivel de circularidad organizacional y reconocer oportunidades de mejora de sus procesos, recursos, productos y estrategias. Para lograrlo, se realizará una revisión de los indicadores disponibles en fuentes bibliográficas académicas relacionados con los pilares de la sostenibilidad en las organizaciones (económico, procesos y sociales) y las estrategias que apoyan la economía circular como: reciclar, rechazar, restaurar, remanufacturar, reducir, reusar, reparar, repensar, recuperar, entre otras. Estos serán analizados y caracterizados de acuerdo a los principios establecidos en la guía GTC314:2020 la cual es la adopción de la BS 8001-2017 que establece la guía marco para la implementación de los principios de la economía circular en las organizaciones. Estos principios serán: pensamiento sistémico, la administración organizacional, la innovación, la optimización del valor, la colaboración y transparencia. El modelo será validado empleando el método Delphi y ajustado según las recomendaciones; posteriormente, será evaluado mediante su aplicación en empresas del sector alimenticio y se espera a partir de sus hallazgos establecer oportunidades de mejora y posibles estrategias a ser tenidas en cuenta por las organizaciones para lograr el máximo aprovechamiento de los recursos naturales y mitigar los impactos en los ecosistemas buscando la carbono neutralidad de las empresas del sector alimenticio.

Desde la creación de la batería de Li-ion en 1985, se han introducido avances significativos en su estructura, especialmente en el uso de cátodos constituidos por óxidos de litio, níquel, manganeso y cobalto (NMC) que mejoraron la densidad de carga, el rendimiento y la seguridad. Sin embargo, el uso de grafito en el cátodo podría ser un paso adicional para potenciar aún más estas características. Mejorar su estabilidad y seguridad sigue siendo un desafío crucial en su desarrollo y uso. El presente estudio propone abordar este desafío mediante la incorporación de grafito en el cátodo de las baterías de ion litio, con el objetivo principal de mejorar su estabilidad. Para lograr este objetivo, se planea llevar a cabo una revisión detallada de la literatura existente sobre el uso de grafito en el cátodo de las baterías de ion litio, seguida de un análisis químico de los componentes actuales de las baterías de litio. Esto incluirá la identificación de los elementos constitutivos, sus pesos y porcentajes. Lo anterior junto a pruebas mediante simulaciones, se utilizará para estudiar el comportamiento de las baterías con dicha configuración. Se espera que los resultados de este estudio muestren una mejora en la estabilidad de las baterías de ion litio, logrando con esto aportar una mayor vida útil a la batería, y salvaguardar su funcionamiento. Además, se tendrán en cuenta consideraciones medioambientales, como la sostenibilidad y el reciclaje de materiales, para evaluar los posibles impactos ambientales de la utilización de grafito en el cátodo, proporcionando una base sólida para futuras investigaciones y desarrollos en el campo de las baterías de ion litio.

El grupo de interés en energías renovables GIER conformado por estudiantes, egresados y profesores de la ETITC tiene dentro de sus propósitos promover la enseñanza de las energías renovables de forma práctica e inmersiva, buscando que este conocimiento sea asequible a todas las comunidades educativas, especialmente a aquellas de difícil acceso a la tecnología y aplicación de las energías renovables en su academia, razones por las cuales ha decidido diseñar y construir un banco de prácticas para la enseñanza del uso de energía solar fotovoltaica, tomando como referencia algunos bancos que se consiguen en el mercado nacional e internacional con un enfoque didáctico e investigativo. Uno de los objetivos de este trabajo, es poder construir bancos para la enseñanza de la energía solar fotovoltaica en la ETITC o en otras instituciones educativas, ya sean de Educación Superior o Enseñanza Media. Para la realización de este proyecto se tienen en cuenta las siguientes etapas: Etapa de definición, donde se hace el levantamiento de datos de los bancos de práctica de las energías renovables existentes en la sede Tintal, de la ETITC, además de las encontradas en el mercado local e internacional. Etapa de diseño preliminar donde se consideran aspectos como funcionalidad, portabilidad, replicabilidad, materiales y sus características físicas, seguridad, entre otros, quedando definidos bosquejos de diseño, para luego escoger el más adecuado que cumpla con los elementos básicos. Etapa de diseño detallado se realiza la memoria detallada de cálculo y el dimensionamiento de los equipos que conforman el banco según los requerimientos planteados en la etapa anterior; se hace un análisis del diseño verificando su funcionalidad práctica y didáctica; y además de la posibilidad del desarrollo de investigación mediante el análisis cualitativo y cuantitativo de piezas que se pueden intercambiar para evaluar las eficiencias de los montajes. En cuanto a la funcionalidad didáctica, se realizan el diseño de las guías didácticas como respaldo al proceso enseñanza -aprendizaje. Etapa de construcción y evaluación se procede a la adquisición de las piezas y materiales que conforman el banco y a la construcción de este, previo a un análisis de costos detallado mediante cotizaciones y trazabilidad presupuestal y finalmente se realiza la evaluación de funcionamiento del banco. Etapa de documentación se hacen pruebas y prácticas que permitan la recolección de datos para evaluar la pertinencia de la transmisión del conocimiento de los estudiantes que interactúan con el equipo, y verificar si los objetivos planteados en las guías desarrolladas y tiempos de ejecución son los esperados y en caso de ser necesario hacer los respectivos ajustes.
Reflexiones necesarias a partir del estado de la ingeniería

La velocidad del desarrollo mundial y el impacto del cambio climático y la inteligencia artificial generan un vértigo de cambios, sobrepasando y limitando las posibilidades de competir. En Colombia, la profesión de ingeniería enfrenta serios problemas como la corrupción que afecta la contratación y produce obras de mala calidad, resultando en construcciones ineficientes y peligrosas. A pesar del potencial de los jóvenes, el futuro es sombrío y es crucial abordar esta realidad de manera positiva. Las vulnerabilidades incluyen la falta de claridad sobre el papel social de la ingeniería, la ausencia de criterio profesional, una cultura de calidad insuficiente y la omisión del riesgo en los análisis, todo enmarcado en una ética práctica deficiente. Esta ponencia explora estas vulnerabilidades y propone soluciones basadas en los pilares 8C: Constructivista, Crítico, Complejo, Calidad, Criterio, Curiosidad, Colectivo y Cambio, que estructuran todas las actividades educativas, teóricas o prácticas, lo que implica una concepción distinta de la universidad que debe prepararse para que los estudiantes vivencien en forma exhaustiva esta nueva forma de aprender y formarse y puedan enraizar la ética práctica que se requiere.
