Relación profesional de la salud-paciente: según la perspectiva de los estudiantes
Authors: K Rhys , A C Carranza
Published: June 2024

INTRODUCCIÓN Los profesionales de la salud cotidianamente se desempeñan en la consulta clínica frente a principios bioéticos como: beneficencia, no maleficencia, autonomía y justicia1,2. Tópicos donde la percepción de profesionales de la salud y pacientes, pueden discrepar.
OBJETIVO: fue determinar la percepción de principios bioéticos vigentes en la comunidad estudiantil, como futuros profesionales de la salud.
MATERIAL Y MÉTODOS: Estudio descriptivo, observacional y transversal. La población en estudio fueron estudiantes de primer año de las carreras de Nutrición y Odontología de la Universidad Católica de Córdoba (UCC), previa firma del consentimiento informado. Completaron anónima y voluntariamente el Cuestionario: Relación Profesional de la Salud-Paciente, validado en la Pontificia Universidad Católica de Chile3,4. El cuestionario constó de cinco dimensiones y 52 preguntas, divididas por dimensiones: Dimensión deshumanización de la salud, Dimensión antropológica y Dimensión relación profesional de la salud-paciente que a su vez tiene diferentes modelos: Paternalista o hipocrático, Tecnológico, Legal, Comercial o consumista y De alianza. A su vez están divididos en relaciones, que por sorteo de dimensiones, modelos y relaciones en este momento solo se expondrá la relación Discriminación y Oferta- Demanda. CONSIDERACIONES ÉTICAS: Estudio aprobado por el Comité de Ética de UCC-Clínica Universitaria Reina Fabiola.
RESULTADOS: El 56% de los estudiantes encuestados piensa que el paciente que puede pagar recibe mejor atención. El 65% considera que al paciente no se lo discrimina por su religión. Los encuestados consideran que se discrimina más por edad, sexo y religión que por homosexualidad. El 62% de encuestados piensa que es mejor firmar documentos legales ante notario y un 72% en algún grado, cree que el profesional debe considerar las consecuencias legales antes de atender al paciente. El 67% de los estudiantes de primer año está en algún grado de acuerdo con la atención, debería seguir las leyes de la oferta y la demanda como cualquier comercio.
CONCLUSIONES: Los estudiantes encuestados opinaron relativamente diferente a lo que se desearía desde la sociedad5 y como futuros profesionales de la salud. Sería interesante repetir la encuesta cuando se encuentren en ejercicio profesional, ya que la relación profesional de la salud-paciente puede determinar el éxito o fracaso del tratamiento.
Optimizing virus filtration for continuous processing using serial filtration at high area ratio
Authors: Giglia Sal , Cacace Benjamin , McCoskey Jacob , Johnson Matthew , Carbrello Christina , Miller Corine , Hersey Joseph
Published: June 2024

Compared to batch operation, continuous bioprocessing can offer numerous
advantages, including increased productivity, improved process control,
reduced footprint, and increased flexibility. However, integration of
traditional batch operations into a connected process can be
challenging. In contrast to batch operations run at constant pressure or
high flux, virus filtration in continuous processes may be operated at
very low flux. This change in operating conditions may reduce the viral
retention performance of the filter which has inhibited adoption of
truly continuous virus filtration. To overcome this limitation, a novel
approach is described that utilizes serial virus filtration, with a high
area ratio between first to second stage filters, to achieve virus
retention targets. In this study, virus filters were operated
continuously (except for planned process interruptions) for 200 hours in
a serial configuration at a first to second stage filter area ratio of
13:1 and at a first stage flux of 5 L/m /hr. While
the minute virus of mice (MVM) retention performance of the first stage
filter was about 4 log reduction value (LRV), there was no virus
detected in the second stage filtrate, translating to an MVM LRV across
the filtration train of ≥6.7. The second stage filter was the dominant
flow resistance at the start of the run but, as it was protected from
foulants by the first stage filter, it suffered minimal fouling and the
life of the filter train was controlled by the first stage. A
theoretical case study projected that continuous virus filtration using
serial configuration at high area ratio would have about 30% longer
filter changeout time, 14% higher productivity, and virus retention
nearly 6 LRV greater than single stage operation. The findings of this
research are expected to provide valuable insights into optimizing virus
filtration in continuous bioprocessing.

Published: June 2024

Globally, urban expansion has led to habitat fragmentation and altered
resource availability thus posing significant challenges for wildlife.
This study analyzed spatial distribution, habitat use patterns, and
anthropogenic impacts on habitat occupancy of the Critically Endangered
Chinese pangolin (Manis pentadactyla) in the urban landscape of Dharan
Sub-metropolitan City, Nepal. Using a single-season occupancy modelling
approach, we investigated the factors influencing the detection
probability and habitat occupancy of Chinese pangolins in 134 grids of
each 600 m × 600 m. Our study identified the role of termite mounds in
influencing detection probability, emphasizing the species’
myrmecophilous behavior. Additionally, the Human Disturbance Index (HDI)
emerged as a significant factor negatively affecting habitat occupancy
of Chinese pangolins. We observed a medium level of anthropogenic
disturbances in the grids where pangolin presence was detected. The
findings emphasize the need for targeted conservation efforts,
considering the fine-scale ecological and anthropogenic factors
impacting Chinese pangolins in urban and peri-urban areas. The results
underscore the urgency of implementing effective conservation measures
to ensure the long-term survival of Critically Endangered Chinese
pangolins in urban environments, not only in Dharan but also in similar
lowlands areas and the Churia range of Nepal.
A Physics-Enhanced Neural Network for Estimating Longitudinal Dispersion Coefficient and Average Solute Transport Velocity in Porous Media
Authors: Meng Yinquan , Jiang Jianguo , Wu Jichun , Wang Dong
Published: June 2024

Dispersion coefficients and the average solute transport velocity are
pivotal for groundwater solute transport modeling. Accurately and
efficiently determining these parameters is challenging due to
difficulties in directly correlating them with pore-space structure. To
address this issue, we introduced the Physics-enhanced Convolutional
Neural Network-Transformer (PhysenCT-Net), an innovative model designed
to concurrently estimate the longitudinal dispersion coefficient and
average solute transport velocity in three-dimensional porous media.
PhysenCT-Net exhibited excellent predictive performance on unseen
testing datasets and significantly reduced computational demands.
Comprehensive evaluations confirmed its robust generalization across
various flow conditions and pore structures. Notably, the longitudinal
dispersion coefficient predictions closely align with established
empirical relationships involving Péclet number, affirming the model’s
physical interpretability and potential to aid in simulating transport
phenomena in porous media.
EFFECTIVENESS OF VARIABLE SELECTION METHODS FOR MACHINE LEARNING AND CLASSICAL STATISTICAL MODELS
Authors: Grzybowska Urszula , Karwański Marek
Published: June 2024

In line with new international financial supervision directives (IFRS9), banks should look at a new set of analytical tools, such as machine learning. The introduction of these methods into banking practice requires reformulation of business goals, both in terms of the accuracy of predictions and the definition of risk factors. The article compares methods for selecting variables and assigning "importance" in statistical and algorithmic models. The calculations were carried out using the example of financial data classification for loan default. The effectiveness of various machine learning algorithms on selected sets of variables was compared. The results of the analyzes indicate the need to revise the concept of the "importance" of a variable so that it does not depend on the structure of the model.

Authors: Akbarian Ehsan , Mohammadi Mehrgan , Tiala Emilia , Ljungberg Oscar , Sharif Razavian Ali , Magnéli Martin , Gordon Max
Published: June 2024

Background and purpose: Artificial intelligence (AI) has the potential to aid in the accurate diagnosis of hip fractures and reduce the workload of clinicians. We primarily aimed to develop and validate a convolutional neural network (CNN) for the automated classification of hip fractures based on the 2018 AO-OTA classification system. The secondary aim was to incorporate the model’s assessment of additional radiographic findings that often accompany such injuries.Methods: 6,361 plain radiographs of the hip taken between 2002 and 2016 at Danderyd University Hospital were used to train the CNN. A separate set of 343 radiographs representing 324 unique patients was used to test the performance of the network. Performance was evaluated using area under the curve (AUC), sensitivity, specificity, and Youden’s index.Results: The CNN demonstrated high performance in identifying and classifying hip fracture, with AUCs ranging from 0.76 to 0.99 for different fracture categories. The AUC for hip fractures ranged from 0.86 to 0.99, for distal femur fractures from 0.76 to 0.99, and for pelvic fractures from 0.91 to 0.94. For 29 of 39 fracture categories, the AUC was ≥ 0.95.Conclusion: We found that AI has the potential for accurate and automated classification of hip fractures based on the AO-OTA classification system. Further training and modification of the CNN may enable its use in clinical settings.

Taking into account new frontiers in materials technology to improve construction materials, we investigate the bending analysis of a Functionally Graded Material (FGM) skew plate using a meshless approach based on Third-order Shear Deformation Theory (TSDT). We assume that the material distribution is functionally graded across the thickness of the skew plate. The proposed approach uses both mixture rule theory and the meshless method. The mixture rule theory is used to estimate the effective material properties of the skew plate.

Published: June 2024

The structural nonlinear aeroelastic analysis of folding wings is conducted by integrating the modified Doublet Lattice Method in this paper. Firstly, a modified Doublet Lattice Method is investigated to relax the aspect ratio limitation of aerodynamic elements, and its correctness is verified through numerical examples. Secondly, the rational function approximation method is discussed, and the modified Doublet Lattice Method is approximated using the minimum state method to obtain the unsteady aerodynamic forces in the time domain. Finally, the aeroelastic characteristics of a folding wing with free-play and friction nonlinearity are studied by integrating time-domain unsteady aerodynamics with the nonlinear structural dynamics model. The results show that the modified Doublet Lattice Method, which relaxes the aspect ratio limitation of aerodynamic grid elements, is feasible and effective; Friction can suppress the influence of free-play nonlinearity on aeroelastic response.

Authors: Fauchon Chloe
Published: June 2024

En virtud de los tratados internacionales y del derecho de la Unión Europea, el sospechoso debe contar con la asistencia de letrado en todo el proceso penal. Ello es aún más adecuado en la Unión Europea cuando lo que se pretende es crear un Espacio de libertad, seguridad y justicia. No obstante, en los procesos transnacionales esta asistencia letrada carece de efectividad. El presente artículo busca identificar las causas de esta falta de eficiencia y proponer soluciones para subsanar esta carencia. Se sugiere establecer una defensa dual, solución que encuentra, sin embargo, dificultades en la hora de su implementación.

España y la nueva Europa. Treinta años del Tratado de Maastricht
Authors: Ree Ree
Published: June 2024

Entre mediados de los años ochenta y principios de los noventa, en el escenario europeo se produjeron una serie de cambios trascendentales. Tras la aprobación del Acta Única en 1986, en 1992 se firmó el Tratado de Maastricht que, dando lugar al nacimiento de la Unión Europea (UE), supuso un salto cualitativo fundamental para el proceso de integración continental surgido después de la Segunda Guerra Mundial. Al mismo tiempo, las políticas promovidas por el líder soviético Mijaíl Gorbachov llevaron al final de la Guerra Fría y al colapso de los regímenes del llamado “socialismo real”, lo que alumbró la esperanza de que el Este y el Oeste de Europa, separados por el Telón de Acero durante más de cuatro décadas, pudieran finalmente volver a encontrarse.

Published: June 2024

La reciente finalización del mecanismo de cooperación y verificación (MCV) en septiembre de 2023 abre la posibilidad de evaluar cuáles han sido los efectos que ha tenido en la mejora del Estado de Derecho en Rumanía y Bulgaria. Este mecanismo se clasifica como de condicionalidad debido a su carácter vinculante para la imposición de sanciones por parte de la Comisión en caso de incumplimiento de las reformas que se pactaron en el Acta de Adhesión para paliar las llamadas deficiencias sistémicas con las que contaban en el Estado de Derecho antes de su adhesión. El objetivo de este artículo consiste en analizar cuál es la utilidad de los procesos de condicionalidad a los que se ven sometidos los Estados candidatos y medir el alcance del MCV como parte de dichos procesos post adhesión.
México y la Sociedad de Naciones
Authors: Nuñez de Prado Clavell Sara
Published: June 2024

La Sociedad de Naciones se instaura en 1920, pero México no está entre los países invitados a unirse, debido, entre otras razones a su actitud durante la guerra relacionado con sus simpatías hacia Alemania y sobre todo con el triunfo de la revolución en el país y las consecuencias que ello podía tener para terceros países, como por ejemplo Estados Unidos. Con el paso del tiempo, México se va relacionando cada vez más con la organización, hasta que en 1931, superando tanto las reticencias de algunos miembros de la Sociedad de Naciones, como las del propio México, que se sentía maltratado desde que había sido excluido en 1920, el país ingresa como miembro de pleno derecho.  Este trabajo se centra tanto en este proceso de acercamiento, como en el papel que el estado mexicano realiza ya como miembro de la Liga de Naciones.

Micro-analysis of earnings and its determinants in eastern cape province of South Africa
Authors: Olawuyi Seyi Olalekan , Mushunje Abbyssinia , Eyinade Gabriel
Published: June 2024

Earnings disparities in South Africa, and specifically the Eastern Cape region are influenced by a complex interplay of historical, socio-economic, and demographic factors. Despite significant progress since the end of apartheid, persistent disparities in earnings continue to raise questions about the effectiveness of policies aimed at reducing inequality and promoting equitable social system. Individual-level dataset from the 2021 South African general household survey were subjected to exploratory analysis, while Heckman selection model was used to investigate the determinants of earnings disparities in the study area. The results showed that majority of the population are not working for a wage, commission or salary, which also pointed to the gravity of unemployment situation in the area of study. Most of the working population (both male and female) are lowest earners (R ≤ 10,000), and this also cuts across all age-group categories. Majority of working population have no formal education, are drop out, or have less than grade-12 certificate, and very few working populations with higher education status were found in the moderate and relatively high earnings categories. While many of the working population are engaged in the informal sector, those in the formal sector are in the lowest earners group. Compared to any other race, the Black African group constituted the majority of non-wage earners, and most in this group were found in the lowest earners group. Some of the working population who were beneficiaries of social grants and medical aids scheme were found in the lowest, low, and moderate earnings categories. The findings significantly isolated the earnings-effect of age, marital status, gender, race, education, geographic indicators, employment sector, and index of health conditions and disabilities. The study recommends interventions addressing racial, gender, and geographic wage gaps, while also emphasizing the importance of equitable access to education, health infrastructure, and skills development.
Modeling the Processes of Land Resources Administration
Authors: Perovych Lev , Perovych Ihor , Perovych Lesia , Ludchak Oksana
Published: June 2024

In this publication, the strategy of land resources administration is presented on the basis of consideration of proposed result factors. The research methodology is based on the use of the PESTLE analytical model in conjunction with economic-mathematical modeling. The scientific novelty of the publication is developing the technology of administration of land resources on the basis of cadastral and other statistical information, which allows obtaining scientifically grounded solutions on the use of land resources. Considering the process of Land Resources Administration as a procedure based on making certain decisions when creating a management system which takes into account the internal and external relationships in this system, the postulate is about determining the degree of trust in this system, establishing economic, environmental and social risks when using it. To a certain extent, the process of Land Resources Administration is a prediction of the effective use of this natural potential in the future. It should be noted that the reliability of the forecast decision depends on the nature and parameters of uncertainties and the duration of their validity. Consequently, while making operational decisions on land resources for a short perspective, the forecasting is more reliable than for a long one. It becomes an effective mechanism of objective evaluation of the state of land resources and the prospects for their use. In this publication the main influencing decision making factors and the technological scheme of the solution of the problem are given.

Does Creativity and Product Innovation Build Business Continuity? Investigation of Samarinda Weaving Craft
Authors: Zainurossalamia Za Saida , Tricahyadinata Irsan , Robiansyah Robiansyah
Published: June 2024

In practice, it is often found that the iconic woven sarong products from Samarinda still produce classic models without any new breakthroughs according to tastes, interests across generations, and market segmentation. Until now, another obstacle has been the difficulty of finding skilled artisans to modernize Samarinda’s woven sarongs. Following up on these dynamics, the manuscript aims to explore the causality between creativity and product innovation on the business continuity of the Samarinda woven sarong craft. In the study context, the independent variable is modified to include creativity and product innovation, while the dependent variable is focused on business continuity. To project the effect of creativity and product innovation on business continuity, a purposive sampling approach was associated with 261 sarong-woven craftswomen in Samarinda who still exist today. From the existing interview data, the data is tabulated using a multiple linear regression technique. Quantitative evidence shows that creativity has a significant effect on business continuity in the Samarinda woven sarong craft, but product innovation has an insignificant effect on business continuity in the Samarinda woven sarong craft. The implications for the future can be evaluated based on this research. Then, further theoretical insights can be expanded by exploring factors beyond creativity and product innovation.

Authors: Pahrudin Pahrudin , Wang Chia-Chun , Liu Li-Wei , Lu Chien , Hak Muhamad Bai’ul
Published: June 2024

Only a few studies on large sports tourism explore motorsport events such as the Moto Grand Prix. The present study addresses this gap by examining the factors influencing visitors’ satisfaction and intention to revisit related to the large sports event of MotoGP, Indonesia. The data were collected from visitors who had attended the MotoGP event in Indonesia using an online questionnaire with purposive sampling. The partial Least Square-Structural Equation Modeling (PLS-SEM) analysis was applied in this study to analyze the data. The findings indicate that hospitality, accessibility, and attraction significantly influenced visitor satisfaction at the MotoGP sports event in Mandalika, Indonesia. However, the factors of hospitality, infrastructure, accessibility, and attraction are insignificant where it concerns visitors’ intention to revisit. Moreover, satisfaction successfully influences visitors to revisit the MotoGP event in Indonesia. This study contributes to research on sports event management in large sports events by examining the factors that influence satisfaction and intention to revisit in the context of the MotoGP sports event, and contributes both theoretically and practically to research on sports events and tourism.

Authors: Muzellina Virly Nanda , Alvianto Steven , Widjanarko Nicolas Daniel
Published: June 2024

Introduction

Colonoscopy is regarded as a safe diagnostic and therapeutic procedure, nevertheless, some patients may still encounter post-colonoscopy gastrointestinal symptoms. This study aimed to evaluate the utilization of probiotics before and after colonoscopy to relieve those symptoms.

Methodology

This study was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) 2020 guidelines. Included studies were all interventional studies examining the effects of probiotics use before and after colonoscopy. Articles were retrieved from MEDLINE, EBSCO-Host, Cochrane, ProQuest, and Google Scholar electronic databases, utilized specific keywords (
“
Probiotic
” OR “
Probiotics
”) AND (“
Colonoscopy
” OR “
Colonoscopies
”). The Cochrane Risk of Bias (RoB) 2 and Joanna Briggs Institute (JBI) Critical Appraisal tools were used for study quality assessment, as well as Review Manager (RevMan) 5.4 to perform the meta-analysis.

Results

A total of ten studies were included in this systematic review. Six studies assessed the effect of probiotics consumption after colonoscopy, three examined the impact before colonoscopy, and one study assessed both. The most common type of probiotics used were Lactobacillus and Bifidobacterium. Quantitative synthesis of probiotics before colonoscopy showed no significant differences among bloating, abdominal pain, nausea, and vomiting symptoms (p=0.49, p=0.14, p=0.30, and p=0.42, respectively). Similarly, quantitative synthesis of probiotics after colonoscopy showed no significant differences in bloating and abdominal pain (p=0.16 and p=0.63, respectively).

Conclusions

Probiotic administration pre- and post-colonoscopy exhibited preliminary evidence for reducing gastrointestinal symptoms, but a quantitative synthesis revealed non-significant findings, necessitating further investigations.

Authors: G. Chavan Abhijeet , Reddy Y.P.
Published: June 2024

Performance of short hydrodynamic journal bearing lubricated with Copper oxide (CuO) nanoparticle suspensions in base oil (nanolubricants) is investigated numerically. Dimensionless pressure, load carrying capacity and friction parameter are calculated by numerical solution of the modified Reynolds equation by means of finite difference method. The particular values of couple stress parameter for nanolubricants are evaluated and used for finding pressure distribution. Modified Krieger Dougherty equation is used to predict the viscosity of nanolubricant. Two short bearing configurations with aspect ratio 0.25 and 0.5 are analyzed by evaluating the pressure profile, load carrying capacity and friction parameter. The comparative results between plain lubricants and nanolubricants are presented. The results reveal improved pressure and load carrying capacity accompanied by decrease in friction parameter of short bearing. The shorter bearing configuration with aspect ratio of 0.25 shows better results than the others.
Comparative Analysis of Wear Behavior of High Entropy Alloy (TiVNbCrAl) and Ti-based Conventional Alloy (TiNbCrCoAl)
Authors: F. Kadhim Dheyaa
Published: June 2024

This research examined the relationships between processing, structure, and property at both room temperature and increased temperature for two BCC high entropy alloy (TiVNbCrAl) and Ti-based conventional alloy (TiNbCrCoAl) prepared using standard arc melting. Both alloys have been determined to have the BCC single-phase solid solution structure. To investigate the hardness and tribological behavior and processes at room temperature and above, microindentation and sliding wear experiments were undertaken. Both alloys display comparable friction behavior when sliding at room temperature, with an average steady-state coefficient of friction (COF) of 0.6. When sliding temperatures rise to 302 °C, the average COF for HEA (TiVNbCrAl) has decreased to a lowest value of ~0.4 due to the creation of a persistent tribochemical layer made of Nb and Cr oxides amid the sliding surfaces, which lowers COF. Whereas, COF for Ti-based conventional alloy remains at higher values of ~0.65. Mechanistic wear analyses revealed that the formation of tribofilms with low interfacial shear strength inside the wear tracks was the cause of this. The tribofilms were identified to be mostly constituted by multi-element solid solution oxides, such as Ni2O5, Cr2O3, and NiO2, according to Raman spectroscopy. The Vickers microharness values for Ti-based conventional alloy is about 365±4 HV. Whereas, for high entropy alloy is about 572±12 HV due to the solid solution strengthening.

In various applications like bearings, gear pairs, and brake pads, understanding how polymer composites interact with harder counterparts during sliding motions is crucial. A challenge arises from the heat generated during sliding friction, which has the potential to raise the contact temperature. This temperature increase, if it exceeds the material's glass transition temperature, can compromise the thermal stability of the composites, leading to rapid material wear. In the present investigation, dry sliding wear test was performed on 25 wt. % of short carbon fiber (SCF) reinforced polyethersulfone (PES) composites filled with 2.5 and 5.0 wt. % of potassium titanate whisker (PTW) using pin-on-disc tribometer. Wear test was planned and executed according to the experiment design formulations obtained by central composite design method. Contact temperature at the interface between composite pin and steel disc was monitored with an infrared thermal camera. Wear resistance was found to increase with the addition of fibers and fillers. PTW filled composites exhibited minimum wear with maximum coefficient of friction. Morphology studies were carried out on worn surfaces of the composites using scanning electron microscope to identify and describe the mechanism of wear involved. This investigation sheds light on the intricate behavior of polymer composites during sliding interactions.
