BackgroundCoronavirus disease 2019 has impacted upon the role and safety of healthcare workers, with the potential to have a lasting effect on their wellbeing. Limited research has been conducted during previous pandemics exploring how student healthcare workers are impacted as they study and train for their professional careers.ObjectiveThe aim of the current study was to examine the specific impact of COVID-19 on the academic, clinical and personal experiences of healthcare students.MethodUndergraduate students across three year groups within the School of Health Sciences at Ulster University completed online Qualtrics surveys at three timepoints during one academic year (2020/2021). Quantitative survey data was downloaded from Qualtrics into SPSS Version 25 for descriptive analysis of each cross-sectional sample. Qualitative survey data was downloaded into text format, which was thematically analysed using content analysis.Results412 students completed the survey at Time 1 (October 2020), n = 309 at Time 2 (December 2020) and n = 259 at Time 3 (April 2021). Academically, the pandemic had mostly a negative impact on the learning environment, the development of practical skills, the assessment process and opportunities for peer learning and support. Students reported increased stress and challenges managing their workload and maintaining a sense of motivation and routine. Clinically, they felt unprepared by the university for placement where the pandemic had an increasingly negative impact over time on learning and skill development. In terms of personal experiences, despite the majority of students taking steps to keep physically and mentally well, negative impacts on friendships, mental wellbeing and concerns for family were reported. The pandemic had not impacted upon career choice for most students.ConclusionConsideration must be given to the development of practical skills so students feel prepared for their professional careers given the practical nature of their roles. Programme coordinators should adopt a holistic approach to student wellbeing.

Published: July 2022

BackgroundScreening program participants with iron overload (IO) phenotypes withoutHFEp.C282Y/p.C282Y are incompletely characterized.MethodsWe studied white participants who had IO phenotypes without p.C282Y/p.C282Y in post-screening clinical examinations (CE). We defined IO phenotypes as a) elevated serum ferritin (SF) and transferrin saturation (TS) at screening and CE, and b) absence of IO treatment, anemia, transfusion >10 units, alcohol intake >30 g/d, hepatitis B or C, and pregnancy. We defined IO-related disease as elevated alanine or aspartate aminotransferase (ALT/AST) or swelling/tenderness of 2nd/3rd metacarpophalangeal (MCP) joints. All participants hadHFEp.C282Y and p.H63D genotyping.ResultsThere were 32 men and 26 women (mean age 54±16 y). Median food/supplemental iron intakes were 14.3/0.0 mg/d. Relative risks ofHFEgenotypes were 12.9 (p.C282Y/p.H63D), 3.0 (p.H63D/p.H63D), 1.9 (p.C282Y/wt), 0.9 (p.H63D/wt), and 0.5 (wt/wt) compared to 42,640 white screening participants without IO phenotypes or p.C282Y/p.C282Y. Regression on SF revealed positive associations: MCV (p = 0.0006; β coefficient = 0.4531); swelling/tenderness of MCP joints (p = 0.0033; β = 0.3455); and p.H63D/wt (p = 0.0015; β = 0.4146). IO-related disease (18 elevated ALT/AST, one swelling/tenderness of MCP joints) occurred in 19 participants (7 men, 12 women). Median MCV was higher in participants with IO-related disease (97 fL vs. 94 fL; p = 0.0007). Logistic regression on IO-related disease revealed a significant association with diabetes (p = 0.0416; odds ratio 18.9 (95% confidence interval 1.0, 341.1)).ConclusionsIn the present 58 screening program participants who had IO phenotypes withoutHFEp.C282Y/p.C282Y, relative risks ofHFEgenotypes p.C282Y/p.H63D, p.H63D/p.H63D, and p.C282Y/wt were significantly higher than in 42,640 white screening participants with neither IO phenotypes nor p.C282Y/p.C282Y. SF was significantly associated with MCV, swelling/tenderness of 2nd/3rd MCP joints, and p.H63D/wt. IO-related disease was significantly associated with MCV and diabetes.

BackgroundInadequate intake of micronutrients in lactating women was prevalent worldwide. In particular, to our knowledge, there has been little report concerning Ethiopian lactating women regarding their micronutrient intake. Our objective was to assess micronutrient intake inadequacy and its associated factors among lactating women in Bahir Dar city, Northwest Ethiopia, 2021.MethodsCommunity-based cross-sectional study was conducted from February 15 to March 05, 2021. Four hundred thirteen respondents were selected through systematic random sampling. Data were collected by interviewer-administered semi-structured questionnaire and a single multiphasic 24 hours dietary recall was used to assess dietary assessment. Data entry and analysis were carried out using EpiData and SPSS respectively. The ESHA food processor, Ethiopian food composition table, and world food composition table have used the calculation of nutrient values of the selected micronutrient. The nutrient intakes were assessed by Nutrient Adequacy Ratio (NAR) and Mean Adequacy Ratio (MAR). Multivariable binary logistic regression analysis was done to identify the factors of overall micronutrient intake inadequacy.ResultThe overall prevalence of micronutrient intake inadequacy across 12 nutrients was 39.9% [95% CI (34.9, 45.0)]. The inadequate intake of vitamin A was 98.2%. Similarly, the inadequate intake of B vitamins ranges from 13.4% to 68.5%. The insufficient intakes of calcium, iron, and zinc were 70.9%, 0%, and 4.7%, respectively. Around 36 and 91.6% of the respondents had inadequate intake of selenium and sodium, respectively. On multivariable logistic regression analysis; Being divorced was 2.7 times more likely to have overall micronutrient intake inadequacy than being married [AOR = 2.71, 95% CI (1.01, 7.33)]. The odds of overall micronutrient intake inadequacy were 2.6 higher in merchants than in housewives [AOR = 2.63, 95% CI (1.40, 4.93)]. Lactating women who had poor nutritional knowledge were 2.7 times more likely to have overall micronutrient intake inadequacy than those who had good nutritional knowledge [AOR = 2.71, 95% CI (1.47, 4.99)].Conclusion and recommendationOverall, the micronutrient intake in lactating women was lower than the recommended levels. Therefore; educating lactating women about appropriate dietary intake is essential.

Authors: Sassera Jorgelina Silvia 
Published: July 2022

Una manifestación de la segmentación socioeducativa es la conformación de circuitos, trayectos o grupos de instituciones educativas con características diferenciales a los que acceden de manera desigual las clases sociales. El artículo explora la existencia de circuitos de la educación secundaria con una perspectiva territorial en la provincia argentina de Chaco, y propone avanzar en el estudio de las desigualdades educativas con una desagregación mayor a los niveles nacional, regional y provincial.
La identificación de los circuitos, es realizada según las características socioeconómicas de los estudiantes, las disparidades en las trayectorias escolares, y las condiciones materiales de escolarización; a tal fin se articularon distintas fuentes de información nacionales y provinciales que fueron estudiadas con un análisis multidimensional.
El análisis permitió identificar a los estudiantes que acceden a los cinco circuitos reconstruidos, y la existencia de segregación según nivel socioeconómico, las disparidades en el acceso y permanencia de los adolescentes, y la desigualdad en los logros en los aprendizajes según el circuito. Un acercamiento a la localización departamental, permitió explorar una posible relación entre la situación de las condiciones de vida de las áreas y las mayores o menores ventajas materiales de las escuelas secundarias según circuito.

Published: July 2022

El contexto de pandemia Covid–19 y la emergencia de medidas sanitarias impactaron fuertemente en el sistema educativo, en general. Particularmente, en la universidad las prácticas de enseñanza presenciales debieron trasladarse a la virtualidad de manera inmediata, adquiriendo rasgos de la enseñanza remota de emergencia.
En el escrito se socializa una experiencia pedagógica correspondiente a la asignatura Tecnología Educativa de la Facultad de Humanidades de la Universidad Nacional del Nordeste (UNNE). La misma se desplegó en tres etapas concatenadas que apuntaban al montaje de planificaciones didácticas en aulas virtuales. Se destaca para su análisis, las estrategias didácticas transversales, la simulación en entornos virtuales y el trabajo colaborativo disciplinario e interdisciplinario, con sus contribuciones en la formación profesional docente.
Ideas clave que emergieron del análisis de encuestas realizadas a los estudiantes hacia el final de la cursada en las cuales se valoraron dichas estrategias. Las conclusiones iniciales dan cuenta de la relevancia que adquieren este tipo de estrategias didácticas para la formación docente ya que permite situar a los estudiantes, futuros profesionales, en el contexto de práctica real y en la toma decisiones para la resolución de situaciones problemáticas emergentes.
Liderazgo gremial y género en el campo argentino: historia de vida de la primera coordinadora nacional de las Mujeres Federadas Argentinas
Authors: Muro María Marta 
Published: July 2022

El escrito se propone recorrer la historia de vida de la primera coordinadora nacional de las Mujeres Federadas Argentinas a la par de algunos hitos en la institución de la que forma parte, la Federación Agraria Argentina. A través de un recorrido biográfico se repone la historia de Susana Olego, y se propone una reflexión sobre el modo en que las mujeres rurales delinearon la agenda pública e institucionalizaron sus apuestas en el órgano que las reunió en la institución. Se busca reconstruir tanto la “vida privada” de la protagonista, que va desde sus prácticas a sus sentimientos y sus vínculos familiares, como su trayectoria educativa, laboral, político gremial sin perder de vista los marcos institucionales y contextuales en que se desarrolla su vida, lo que permite mostrar una trama íntima y comprometida de mujeres que se movilizaron para generar cambios sustantivos en espacios donde estaban invisibilizadas, como lo es el rural.

The Frankfurt institute at 100: The perspective of a trichotomic critical theory
Authors: Hrubec Marek 
Published: July 2022

Abstract
This article was written on the occasion of the 100th anniversary of the Institute for Social Research in Frankfurt am Main, where the Frankfurt School was founded and continues to evolve. From philosophical and interdisciplinary perspectives, the article focuses on the trichotomic characteristics of critical theory, specifically: critique, explanation, and normativity. It looks first at the founding of the Institute for Social Research; second, at the emergence of critical theory at the Institute; and third, at how these ideas evolved. It identifies trichotomy underpinning Horkheimer’s approach to critical theory. In the conclusion, the revisions made to critical theory in the later stages of development are considered.
Airborne LiDAR data in landscape archaeology. An introduction for non-archaeologists
Authors: Štular Benjamin , Lozić Edisa 
Published: July 2022

AbstractThe use of airborne LiDAR data has become an essential component of landscape archaeology. This review article provides an understandable introduction to airborne LiDAR data processing specific to archaeology with a holistic view from a technical perspective. It is aimed primarily at researchers, students, and experts whose primary field of study is not archaeology. The article first outlines what the archaeological interest in airborne LiDAR data is and how the data processing workflow is archaeology-specific. The article emphasises that the processing workflow is riddled with archaeology-specific details and presents the key processing steps. These are, in order of their impact on the final result, enhanced visualisation, manual reclassification, filtering of ground points, and interpolation. If a single most important characteristic of airborne LiDAR data processing for archaeology is to be emphasised, it is that archaeologists need an archaeology-specific DEM for their work.
From LiDAR to deep learning: A case study of computer-assisted approaches to the archaeology of Guadalupe and northeast Honduras
Authors: Lyons Mike , Fecher Franziska , Reindel Markus 
Published: July 2022

Abstract
Archaeologists are interested in better understanding matters of our human past based on material culture. The tools we use to approach archaeological research questions range from the trowel and brush to, more recently, even those of artificial intelligence. As access to computing technology has increased over time, the breadth of computer-assisted methods in archaeology has also increased. This proliferation has provided us a considerable toolset towards engaging both new and long-standing questions, especially as interdisciplinary collaboration between archaeologists, computer scientists, and engineers continues to grow. As an example of an archaeological project engaging in computer-based approaches, the Guadalupe/Colón Archaeological Project is presented as a case study. Project applications and methodologies range from the regional-scale identification of sites using a geographic information system (GIS) or light detection and ranging (LiDAR) down to the microscopic scale of classifying ceramic materials with convolutional neural networks. Methods relating to the 3D modeling of sites, features, and artifacts and the benefits therein are also explored. In this paper, an overview of the methods used by the project is covered, which includes 1) predictive modeling using a GIS slope analysis for the identification of possible site locations, 2) structure from motion (SfM) drone imagery for site mapping and characterization, 3) airborne LiDAR for site identification, mapping, and characterization, 4) 3D modeling of stone features for improved visualization, 5) 3D modeling of ceramic artifacts for more efficient documentation, and 6) the application of deep learning for automated classification of ceramic materials in thin section. These approaches are discussed and critically considered with the understanding that interdisciplinary cooperation between domain experts in engineering, computer science, and archaeology is an important means of improving and expanding upon digital methodologies in archaeology as a whole.
New quantum integral inequalities for some new classes of generalizedψ-convex functions and their scope in physical systems
Authors: Rashid Saima , Parveen Saima , Ahmad Hijaz , Chu Yu-Ming 
Published: July 2022

AbstractIn the present study, two new classes of convex functions are established with the aid of Raina’s function, which is known as theψ-s-convex andψ-quasi-convex functions. As a result, some refinements of the Hermite–Hadamard ({\mathcal{ {\mathcal H} {\mathcal H} }})-type inequalities regarding our proposed technique are derived via generalizedψ-quasi-convex and generalizedψ-s-convex functions. Considering an identity, several new inequalities connected to the{\mathcal{ {\mathcal H} {\mathcal H} }}type for twice differentiable functions for the aforesaid classes are derived. The consequences elaborated here, being very broad, are figured out to be dedicated to recapturing some known results. Appropriate links of the numerous outcomes apprehended here with those connecting comparatively with classical quasi-convex functions are also specified. Finally, the proposed study also allows the description of a process analogous to the initial and final condition description used by quantum mechanics and special relativity theory.
A New Hydraulic Fracturing Instrument to Measure In Situ Stress and Its Application in Chahasu Coal Mine
Authors: Xu Qiang , Yao Qiangling , Shan Changhao , Zheng Chuangkai 
Published: July 2022

Abstract
Accurate measurements of the in situ stress of the mining area in coal mines are crucial for roadway layouts, support designs, and for coal mining technology selections. Based on the principle of hydraulic fracturing, this study proposes a newly developed instrument, named the instrument for single-loop pneumatic pressurization in situ stress measurements (RBHST-50) and presents its measurement procedures. This instrument boasts four advantages for in situ stress measurements in coal mines: (1) As a safe dynamic in underground coal mines, compressed air provides the driving force of the fracturing fluid; (2) the instrument, which is small and lightweight, can be transported easily from one test point to another; (3) the process of plugging and fracturing is controlled by a simple-loop control system, which avoids the problem of borehole blocking; and (4) the adoption of the integrated impression packer saves the time of conversion between the borehole wall fracturing program and the fracturing impression program, eliminating the error of in situ stress orientation caused by fracture closure. Field investigation was performed in Chahasu Coal Mine in China. The investigation results show that the in situ stress field of Chahasu Coal Mine is dominated by tectonic horizontal stress fields and mainly influenced by the West-North-West tectonic compressive stress, which agrees well with the evaluation results of regression formula. In summary, the proposed RBHST-50 instrument can measure the magnitude and orientation of in situ stress in the coal mine rapidly and accurately while achieving good water plugging capabilities.
Ship Dynamic Positioning Control Based on Nonlinear Fuzzy Algorithm for a Smart Port City
Authors: Xiao Jinfeng 
Published: July 2022

Abstract
Aiming at the difficulty of the dynamic positioning process and trajectory control under the influence of complex disturbance, ship dynamic positioning control based on the nonlinear fuzzy algorithm is studied. By analyzing the composition and task of the ship dynamic positioning system, the nonlinear characteristics of the ship dynamic positioning system are obtained, and the ship dynamic pose is described by the combined coordinate system of the geodetic coordinate system, ship hull coordinate system, and multi-degree-of-freedom coordinate system. The dual fuzzy proportional, integral, derivative (PID) algorithm is applied to the point control and surface control and an approximate algorithm is adopted to calculate the target control parameters, so as to enhance the comprehensive effectiveness of ship hull nonlinear control results. The experimental results show that the control effect of this method is better and the heading angle control error is smaller. Meet the dynamic positioning ship control needs.
