Pandemic and Economy: An Econometric Analysis Investigating the Impact of COVID-19 on the Global Tourism Market
Authors: Varzakas Ioannis-Panagiotis , Metaxas Theodore
Published: April 2024

With the outbreak of the COVID-19 pandemic, the global tourism market has become one of the most affected sectors of the economy. In this research, the literature on the economic effects created by COVID-19 on a global level is first studied and the measures and restrictions that governments are obliged to take in order to suppress and prevent the spread of the coronavirus are analyzed. Next, there is an attempt to empirically estimate a system of equations regarding the two channels of influence of COVID-19 on tourism, making use of cross-sectional data, and specifically for a sample of 38 countries that launched vaccination up until the end of 2020. The explained results confirm that tourism is directly affected by the spread of COVID-19, due to the effort of travelers to avoid illness, but also due to the measures taken by governments to limit it. Tourism is also indirectly affected, due to the negative impact on income. Using 3SLS, an equation was developed to calculate the direct and indirect impact of COVID-19 on tourism. Notably, the dependent variable (tourism expenditure) exhibited a positive correlation with the independent variable (GDP) and a negative correlation with the total COVID-19 cases. Consequently, it was determined that a unit increase in the COVID-19 variable led to a reduction in international tourism expenditure by USD 859,237. Finally, there is a concern, and further investigation is needed, regarding the effect of vaccination against COVID-19 on tourism, which, while it is expected to be negative, is not confirmed by the results.

Published: April 2024

Active-case finding (ACF) using chest X-ray is an essential method of finding and diagnosing Tuberculosis (TB) cases that may be missed in Indonesia’s routine TB case finding. This study compares active and passive TB case-finding strategies. A retrospective study of TB case notification was conducted. Data between 1 January and 31 December 2021, was used. The population in this study were TB cases notified from Kulon Progo District health facilities, including those found through routine activities or active-case findings. A total of 249 TB cases were diagnosed in Kulon Progo in 2021, and 102 (41%) were bacteriologically confirmed. The TB patients’ ages ranged from 0 to 85 years (median 52, IQR 31–61). The majority of cases were male (59%, 147/249) and mostly among people aged 15–59 (61.4%, 153/249). The proportion of clinical TB diagnoses among cases found from active-case findings was 74.7% (68/91) while the proportion among passive-case findings was 50% (79/158). Active-case finding contributed 91 (36.5%) TB cases to the total cases detected in Kulon Progo in 2021. The use of chest X-rays in active-case findings likely contributed to the detection of a higher proportion of clinical TB than in passive-case findings.

Published: April 2024

A seroepidemiological study was conducted in 2018 to assess diphtheria and tetanus antibodies in Guangzhou, China. Diphtheria and tetanus antibody concentrations were measured with an enzyme-linked immunosorbent assay. A total of 715 subjects were enrolled in the study. The overall diphtheria and tetanus toxoid IgG-specific antibody levels were 0.126 IU/mL (95% CI: 0.115, 0.137) and 0.210 IU/mL (95% CI: 0.185, 0.240), respectively; the overall positivity rate was 61.82% (95% CI: 58.14, 65.39) and 71.61% (95% CI: 68.3, 74.92), respectively. The diphtheria and tetanus antibody concentration was decreased by age and increased by doses. The geometric mean concentrations and positivity rate of diphtheria and tetanus antibodies were lowest and below the essential protection level in people over 14 years of age. Compared to children and adolescents, middle-aged people and the aged are at much higher risk of infection with Corynebacterium diphtheriae and Clostridium tetani. The current diphtheria and tetanus immunization schedule does not provide persistent protection after childhood. There is an urgent need to adjust the current immunization schedule.

Authors: Mercier Victor , Azib Toufik , Ceschia Adriano , Larouci Cherif
Published: April 2024

This study presents a decision-support methodology to design and optimize modular Boost converters in the context of fuel-cell electric vehicles. It involves the utilization of interleaved techniques to reduce fuel-cell current ripple, enhance system efficiency, tackle issues related to weight and size concerns, and offer better flexibility and modularity within the converter. The methodology incorporates emerging technologies by wide-bandgap semiconductors, providing better efficiency and higher temperature tolerance. It employs a multiphysical approach, considering electrical, thermal, and efficiency constraints to achieve an optimal power architecture for FCHEVs. Results demonstrate the advantages of wide-bandgap semiconductor utilization in terms of volume reduction and efficiency enhancements for different power levels. Results from one of the considered power levels highlight the feasibility of certain architectures through the utilization of WBG devices. These architectures reveal improvements in both efficiency and volume reduction as a result of incorporating WBG devices. Additionally, the analysis presents a comparison of manufacturing cost between standard and wide-bandgap semiconductors to demonstrate the market penetration potential.

Published: April 2024

The worldwide commitment to the electrification of road transport will require a broad overhaul of equipment and infrastructure. Heavy-duty trucks account for over one-third of on-road energy use. Electrified roadways (e-Hwys) are an emerging technology where electric vehicles receive electricity while driving via dynamic wireless power transfer (DWPT), which is becoming highly efficient, and can bypass the battery to directly serve the motor. A modeling study was undertaken to compare long-haul trucks on e-Hwys with conventional battery technology requiring off-road recharging to assess the most favorable pathway to electrification. Detailed data taken from on-road driving trips from five diesel transport trucks were obtained for this study. This on-road data provided the simulations with both real-life duty cycles as well as performance targets for electric trucks, enabling an assessment and comparison of their performance on e-Hwys or with fast recharging. Battery-only trucks were found to have lifetimes down to 60% original battery capacity (60% SOH) of up to 9 years with 1600 kWh packs, and were similar to conventional diesel truck performance. On e-Hwys smaller pack sizes in the 500 to 900 kWh capacity range were sufficient for the driving duty, and showed lifetimes upwards of 20 years, comparing favorably to the battery calendar life limit of about 26 years. For a 535 kWh battery pack, an e-Hwy DWPT level of 250 kW was sufficient for a 36 tonne truck to complete all the daily driving as defined by the diesel reference trucks, and reach a battery pack end of life point of 60% SOH.

The aim of the study is to examine the accumulation of heavy metals (HMs) in trophic levels (soil, wood, tree leaves and fungi of various evolutionary origin) of forest ecosystems.
Materials and Methods. The authors examined soil, wood, leaves and fungi in forests with different anthropogenic load intensity. The collecting grounds were selected according to forest management materials. In total, 26 grounds were examined. Sampling of soil and fungi of various trophic levels was carried out on different substrates, in different forest conditions and under different levels of technogenic impact. Leaf and wood samples were taken from phytopathogen-affected and healthy trees. Chemical sample analysis was carried out using a Kvant atomic absorption spectrophotometer.
Results. The total heavy metal content in fungi is higher than in wood, but lower than in soil. The total heavy metal content in leaves of Norway maple affected by Rhytisma acerinum is higher compared to the leaves from heathy trees. Iron predominates among the heavy metals found in the fungi under consideration; cadmium content is minimal.
Conclusion. The largest amount of accumulated heavy metals was found in the fruiting bodies of the facultative saprotroph, and the smallest amount was in the bodies of the facultative parasite. The forest type and growing conditions affect the heavy metal content in ecosystems.

Prostate cancer is one of the most commonly diagnosed cancers worldwide. Targeted therapy is an anticancer strategy using short peptides targeting prostate-specific membrane antigen (PSMA). However, short peptides have a number of disadvantages, including low stability in vivo. This problem can be solved by using toxins with an inhibitory cystine knot with a short built in peptide.
The aim of the study is to examine the stability and ability of the PSMA/C1-C2 peptide, created on the base of knottin U5-scytotoxin-Sth1a and a short peptide tropic to PSMA, to bind to receptors on the surface of prostate cancer cells and to compare the results with a market image drug PSMA I&T and a specific PSMA inhibitor.
Materials and Methods. A solid-phase peptide synthesizer was used for peptide synthesis, chromatography and mass spectrometry were applied for analysis and purification. A competitive inhibition analysis was performed with radiolabeled commercial PSMA I&T in excess of PSMA/C1-C2 and FAM-labeled PSMA/C1-C2 with a specific PSMA inhibitor 2-PMPA. PSMA-positive culture 22Rv1 and PSMA-negative culture PC-3 were used as cell cultures. Chromatography was used to access peptide stability.
Results. As a result, it was observed that the synthesized PSMA/C1-C2 structure, created on the basis of knottin and a short peptide, prevents binding of PSMA I&T to receptors on the surface of 22Rv1 cells. The decrease in PSMA/C1-C2 binding in the presence of 2-PMPA suggests that PSMA/C1-C2 is targeted for prostate-specific membrane antigen. In addition, PSMA/C1-C2 peptide has increased stability compared to PSMA I&T.

Les modèles de lecture, proposés en psychologie cognitive, se proposent de décrire les connaissances et opérations cognitives qui sous-tendent la prononciation des séquences écrites. De nombreux modèles ont été élaborés qui tentent de rendre compte tant de la lecture adulte experte que des comportements pathologiques de lecture. Cet article a pour but d’exposer les principales conceptions théoriques proposées jusqu’ici. Seront ainsi successivement présentées les conceptions développées dans le cadre des modèles cognitivistes de lecture dits «à deux-voies», des modèles analogiques et des modèles connexionnistes. L’intérêt et les limites de chacune de ces approches seront discutés, nous amenant à proposer un modèle connexionniste original de la lecture.
La dynamique phonographique actuelle dans l’orthographe française
Authors: Lucci Vincent
Published: April 2024

La phonographie du français (comme de toute écriture) ne constitue pas un principe figé et immuable. L’observation des changements des prononciations, des erreurs orthographiques les plus fréquentes, des emprunts, des créations néologiques écrites, autorise à considérer ces phénomènes, dans leur complexité mouvante, comme des indicateurs de changements en cours. On parle dans ce cas — comme pour l’oral — de «dynamique synchronique». Cependant, les erreurs des usagers constituent une dynamique d’un type particulier, qu’on peut qualifier de «individuelle» ou — paradoxalement — de «bloquée».

Les conduites narratives chez l’enfant : une approche étho-linguistique et développementale
Authors: Colletta Jean-Marc
Published: April 2024

La présente contribution examine la manière dont les enfants de 6 à 11 ans mobilisent leurs ressources corporelles (voix, posturo-mimo-gestualité, regards) lorsqu’ils racontent à l’oral un événement vécu. L’analyse multimodale d’une quarantaine de récits fait apparaître une très nette évolution des conduites narratives en fonction de l’âge, évolution qui affecte en même temps les aspects linguistique, prosodique et kinésique de ces conduites. Les résultats obtenus montrent la pertinence d’une approche étho-linguistique en matière de description des conduites langagières enfantines et de leur développement.

Factors influencing students’ academic achievement: evidence from University of Ha’il Kingdom of Saudi Arabia
Authors: Khan Imran
Published: April 2024

The current study's goal is to determine the effect of "student interest," "perceived self-efficacy," and "learning motivation" on undergraduate students' CGPA. The present investigation employed a quantitative methodology, utilizing a cross-sectional survey delivered through an online Google Form that participants self-administered. The current study's target demographic was undergraduate students at a public university. In this survey, 230 undergraduate students took part. The variable combination predicted approximately 39.6% of the overall variance in predicting the CGPA. The predicted regression model in the study was significant (F(3,226 = 50.960, p 0.001), and it discovered that other than "students' interest," only two factors significantly predicted the outcome variable CGPA. However, "student interest" has a positive but negligible effect on the CGPA. It is recommended that teachers use effective classroom strategies to assist students in raising their interest, learning motivation, and self-efficacy to accelerate their academic achievement.

Despite notable advancements in cancer therapeutics, metastasis remains a primary obstacle impeding a successful prognosis. Our prior study has identified heme oxygenase 2 (HO2) as a promising therapeutic biomarker for the aggressive subsets within tumor. This study aims to systematically evaluate HO2 as a therapeutic target of cancer, with a specific emphasis on its efficacy in addressing cancer metastasis. Through targeted inhibition of HO2 by TiNIR (tumor-initiating cell probe with near infrared), we observed a marked increase in reactive oxygen species. This, in turn, orchestrated the modulation of AKT and cJUN activation, culminating in a substantial attenuation of both proliferation and migration within a metastatic cancer cell model. Furthermore, in a mouse model, clear inhibition of cancer metastasis was unequivocally demonstrated with an HO2 inhibitor administration. These findings underscore the therapeutic promise of targeting HO2 as a strategic intervention to impede cancer metastasis, enhancing the effectiveness of cancer treatments.

Mangrove management in China is converting from emphasis on occupied area to intrinsical quality. Mangrove species have varied ecological values, e.g., those having well-developed prop roots are more beneficial for coastal stabilization. The detailed distribution of mangrove species on a national scale remains a challenge, impeding species-specific applications in the ecology and management of mangroves, as well as evaluations of related Sustainable Development Goals. Although local-scale studies have explored various data sources, the variability of plant phenology is the key factor preventing their generalization from local areas to large latitudinal spans (e.g., the coast of China). The separability time period, defined by a separability metric for each scene of the image time series, provides a potential way to tackle the aforementioned problem. We conducted a case study on mapping
Kandelia obovata
in China based on Sentinel-2 time-series imagery, as it is a representative native mangrove species with the largest latitudinal span and tolerance to low temperatures. The proposed approach considered the separability between
K. obovata
and its typical co-occurring mangrove species, as well as that between
K. obovata
and salt marshes. The overall accuracy of the generated
K. obovata
map in China for 2020 reached 88.5% based on independently collected samples. The proposed approach is transferable to diverse mangrove species that inhabit a vast latitudinal span. The implications for sustainable mangrove management were discussed to reveal the benefits to precise management of mangroves, accurate biomass and carbon estimations accounting for species differences, and effective evaluation of mangrove ecosystem services.
Copper-Bearing Metal-Organic Framework with Mucus-Penetrating Function for the Multi-Effective Clearance of Mucosal Colonized

Published: April 2024

Helicobacter pylori
colonizes over 50% of people worldwide. Biofilm formation through penetrating gastric mucus and resistance acquired by
H. pylori
markedly reduces the efficacy of traditional antibiotics. The present triple therapy and bismuth-based quadruple therapy inevitably causes intestinal flora disturbance and fails to address the excessive
H. pylori
-triggered inflammatory response. Herein, a mucus-permeable therapeutic platform (Cu-MOF@NF) that consists of copper-bearing metal-organic framework (Cu-MOF) loaded with nitrogen-doped carbon dots and naturally active polysaccharide fucoidan is developed. The experimental results demonstrate that Cu-MOF@NF can penetrate the mucus layer and hinder
H. pylori
from adhering on gastric epithelial cells of the stomach. Notably, released Cu
2+
can degrade the polysaccharides in the biofilm and interfere with the cyclic growing mode of “bacterioplankton ↔ biofilm”, thereby preventing recurrent and persistent infection. Compared with traditional triple therapy, the Cu-MOF@NF not only possesses impressive antibacterial effect (even include multidrug-resistant strains), but also improves the inflammatory microenvironment without disrupting the balance of intestinal flora, providing a more efficient, safe, and antibiotic-free new approach to eradicating
H. pylori

Published: April 2024

Among the metal oxide nanoparticles, zinc oxide (ZnO) has recently been cited as the new material of the future due to its unique properties and wide application areas. In this study, we offer a simple technique for the production of extremely stable ZnO nanoparticles (CA-ZnO NPs) using the aqueous and ethyl alcohol (1/1, v/v) extract of Cupressus arizonica (CA, Blue cypress) leaves and cones and zinc acetate (Zn-Ac) salt. The structure of the produced CA-ZnO NPs was elucidated and nanoparticles were used as a photocatalyst for the removal of textile dyestuffs. The particle sizes of CA-ZnO NPs calcined at different temperatures (60ºC, 150ºC, and 400ºC) increased from 20 nm to 50 nm. Produced CA-ZnO NPs were used to investigate photocatalytic degradation of Basic Yellow (BY28), Basic Violet 39 (BV39), Methylene blue (MB), Brilliant Blue (BB3) and Basic Red 46 (BR46) in aqueous solution under UV- light and daylight irradiation. After stirring dye solutions containing CA-ZnO NP for one hour in darkness and 7 hours under UV- light, decolorization rates varied from 53% to 100%. Decolorization of the dyestuff molecules follows the pseudo first-order kinetics. Produced CA-ZnO NPs showed antibacterial efficiency against Escherichia coli and Staphylococcus aureus. CA-ZnO NPs formed zones ranging from 10 mm to 11 mm against gram+ and gram- bacteria. Green production of ZnO NPs utilizing Cupressus arizonica plant extract can replace chemical methods, and the resulting CA-ZnO NPs can be used in industries like water purification. This eco-friendly biogenic synthesis method is a new, inexpensive and useful technique suitable for large scale.

Theoretical determination of histories and carbon concentration profiles
in steel resulted from a thermochemical process at a frontier
Authors: Téllez-Martínez Jorge Sergio
Published: April 2024

Steel is used to manufacture auto parts due to its properties
and the ability to modify them through solid-state thermal
processing. In some cases, the treated alloy itself does not
satisfy the requirements of combined properties in the
integrity of a single part. In these cases, thermochemical
treatments do apply, with which the chemical composition
does alter in a localized way. The mechanism of atomic
diffusion in the solid is the mean by which atoms of a
chemical element can mobilize in the lattice of the
crystalline structure and concentrate, depending on the
distance penetrated. The mass transport equation
adequately describes concentration gradients if the
diffusivity property is precisely known. The applicability
to the analysis of the carburization method of steel can do
a micrometric scale in one dimension. The results obtained
on a computer application calculating the carbon
concentration profile in iron can be shown. The strategy
consists of qualitatively evaluating the distribution of
equilibrium phases by optical microscopy and associating
it with the carbon concentration profile.

Published: April 2024

Introducción: desde 2006, la encuesta del nutritionDay liderada por la European Society of Clinical Nutrition and Metabolism (ESPEN) y la Universidad de Viena ha permitido evaluar las prácticas nutricionales en pacientes en unidades de cuidados intensivo (UCI) y salas generales. En este artículo se analizan la estructura de las UCI y se examinan las características clínicas y nutricionales de pacientes críticamente enfermos en Colombia.
Método: estudio observacional de corte transversal que involucró a 13 UCI y 183 pacientes que participaron en el nutri-tionDay 2021. Se llevó a cabo un análisis descriptivo de variables estructurales y demográficas, clínicas y nutricionales de los pacientes utilizando el software estadístico Stata.
Resultados: el 84,6 % de las UCI eran polivalentes, y las patologías cardíacas (27,3 %) y neurológicas (18,8 %) fueron las más frecuentes. La edad media fue de 61,5 años, el 56,9 % de sexo masculino y un peso promedio de 66 kg. El 69,2 % de las instituciones contaba con una unidad de nutrición, el 100 % tenía profesionales en nutrición y dietética, y el 92,3 % tenía procedimientos de atención nutricional por escrito. En cuanto a las prácticas nutricionales, el 92,3 % de las UCI evalúa el estado nutricional utilizando parámetros de laboratorio y el 76,9 % con peso/talla. La nutrición enteral se utilizó con mayor frecuencia (33,5 %) en comparación con la nutrición parenteral (8,1 %), con una duración promedio alrededor de 4 días. El promedio de estancia fue de 11 días en la UCI y 22,5 días en el hospital.
Conclusiones: este estudio identificó debilidades en la estructura e implementación de los protocolos de nutrición en las UCI. Esto resalta la necesidad de promover prácticas adecuadas para la intervención nutricional en pacientes críticos lo que podría impactar positivamente en los resultados de salud y en la eficiencia de los costos de atención médica en el futuro.

Tomamos como punto de partida del análisis la conformación de un espacio de acción, representación y movilización de sectores excluidos del trabajo asalariado formal que buscó redefinir el problema público de la pobreza a partir de la visibilización de un conjunto de prácticas sociales, laborales y comunitarias como “trabajo de la economía popular”. Este fenómeno permeó el discurso y las prácticas de las organizaciones territoriales, introduciendo nuevas condiciones para la acción colectiva de los sectores populares. Sobre la base de este escenario, el objetivo principal de este estudio es comprender cómo se configuró la experiencia de trabajadores y trabajadoras de la economía popular vinculadas al Movimiento de Trabajadores Excluidos (MTE) del Gran La Plata durante el período 2016-2021. A lo largo de este estudio, mostramos los múltiples modos en que diversas formas del trabajo, la política y el cuidado se entrelazan en este proceso, a través del encuentro entre los mundos de vida de los sujetos y las formas organizativas. Las trayectorias de vida de los y las trabajadoras, las tramas relacionales en las que estos participan, los procesos de construcción del compromiso y las prácticas y sentidos de la participación se constituyen como dimensiones de análisis centrales de esta investigación. A través del recorrido por estos ejes, la experiencia revela sus desbordes respecto de sentidos asociados a lo sindical-laboral y cobra inteligibilidad articulada a procesos de sostenibilidad de la vida. Esta investigación se sustenta en una estrategia metodológica cualitativa basada en la realización de entrevistas en profundidad a trabajadores y trabajadoras rurales, textiles y sociocomunitarias que participan del Movimiento de Trabajadores Excluidos. De manera complementaria, recurrimos al análisis de fuentes primarias tales como artículos periodísticos, publicaciones de las organizaciones en medios digitales y documentos gubernamentales (principalmente, resoluciones ministeriales, decretos y leyes nacionales).

In ensuring TVET graduates have been equipped with a good level of competency and are ready for industrial revolution 4.0 needs, a lot of initiatives have been introduced by the National TVET Council (MTVET), universities and TVET institutions providers. But there is still a phenomenon where the industry questions the quality of TVET graduates, particularly in the aspects of knowledge and skills. In making the TVET students able to capture and realize the real working environments and practices during the process of teaching and learning, TVET educators need to instill the elements of contextual knowledge into their curriculum design. Having a contextual teaching and learning approach in the education system has been proved by many scholars that it has had a good impact on making the students involved in meaningful learning processes by connecting them to real-life situations and linking them on how to apply it in the workplace and everyday life. Thus, this present study has investigated the utilization of contextual knowledge in teaching and learning electrical technology courses among TVET educators. An explanatory sequential mixed method research design has been followed to conduct this investigation study. Two phases of data collection have been involved and the priority has been given to quantitative data and followed by qualitative research data. The population for this study is electrical technology program lecturers from the Vocational Colleges in Malaysia. Findings from this study are expected to give a current visual of contextual knowledge levels among TVET educators that have been instilled in the teaching and learning process. In future research, all the significant findings from this study can be utilized for conducting follow-up research on developing a framework of contextual knowledge in teaching and learning for TVET educators.

The study aims to investigate the application of the vocational taxonomy domain in practice classes, PdP, and the assessment of vocational subjects. To achieve the goals of this study, the researcher has developed four objectives: (a) Determine the level of understanding technical and vocational instructors have regarding the domain of vocational taxonomy; (b) Identify the specific domain of vocational taxonomy that is utilized by technical and vocational tutors in the instruction and learning of vocational subjects; (c) Identify the domain of vocational taxonomies that is applied to practical vocational practices in the technical and vocational professors' classrooms; and (d) Determine the domain specific to vocational taxonomy. This study examines respondents' perspectives using a case study design. For the data quotation, 59 respondents in total participated. In terms of interpreting the min score, respondents strongly agreed with (a) (min=4.71; s.p=0.511), (b) (min=4.67; p=0.462), and (c) (min=4.7; s.p=0.487). Thematic analytics identify several important developing themes based on the thematic analysis, such as the use of the vocational taxonomy domain in practical classes, assessments, and teaching and learning. The findings of this study can assist and enable TVET lecturers in designing instruction, as well as educational policymakers in implementing vocational taxonomy into state education policy. In order to enhance the usability of vocational taxonomy, it is suggested that technology be integrated more extensively and practice classes be expanded.
ONLINE QUIZZES IN IMPROVING STUDENT LEARNING
Authors: Baba Rahim Norizan
Published: April 2024

Distance learning educators include self-assessment formative quizzes into the curriculum to enhance students’ learning experiences. Online quizzes are a useful learning tool, particularly when courses are delivered online, thanks to technical advancements in web-based delivery. The greatest aspect of offering online quizzes is that the correct answer and any suitable comments are offered to students instantly after they complete a question. The present study evaluates students’ overall performance in one of the core courses, in which self-assessment quizzes were administered through the e-learning system in order to reflect their learning behaviour towards the coursework. As part of formative assessment, it was noted that students’ frequent efforts aggregated during the final exam session; yet, as soon as the quizzes were made available, a few students took them. The data demonstrated a substantial link between students who took the quizzes and their overall achievement as measured by final grades. This paper delves through the essential factors to consider when developing well-crafted quizzes for technical courses and so maximising their potential as an effective learning tool.
