Authors: Navas-López Eduardo Adam 
Published: February 2023

Esta investigación correlacional de enfoque de métodos mixtos, cuantitativo y cualitativo, constituye un acercamiento a la caracterización transversal del desarrollo del Pensamiento Algorítmico en los estudiantes de las carreras de Licenciatura en Matemática y Licenciatura en Estadística de la sede central de la Universidad de El Salvador, en el período de 2018 a 2020.

La parte cuantitativa consiste de aplicar un instrumento de medición del nivel de desarrollo del Pensamiento Algorítmico a cuatro grupos de alumnos (80 alumnos en total) de las carreras mencionadas, a medida que los educandos de estas carreras van aumentando su nivel académico de acuerdo al pensum, específicamente a través de las asignaturas que requieren y están relacionadas con la programación de computadoras.
Se encontró una correlación moderada entre este avanze en el nivel académico y el nivel de desarrollo del Pensamiento Algorítmico. Así mismo no se encontró una correlación significativa entre el nivel de desarrollo del Pensamiento Algorítmico y las notas globales de los estudiantes, ni su edad, ni su género.

La parte cualitativa comprende un estudio profundo de los procesos cognitivos que realiza un grupo de educandos de esas mismas carreras (14 alumnos en total) durante la resolución de problemas matemáticos cuya solución es un algoritmo.
Se encontró que los alumnos desarrollan el Pensamiento Algorítmico muy lentamente y con muchos obstáculos, especialmente en el proceso de analizar los problemas. También se encontró mucha variación en el desarrollo de este tipo de pensamiento entre los alumnos. Unos lo han desarrollado aceptablemente y otros lo han desarrollado muy poco.

Los productos teóricos de este trabajo son: (a) el desarrollo de una definición operacional propia de Pensamiento Algorítmico, (b) su correspondiente rúbrica de evaluación genérica, (c) una rúbrica específica, y (d) un nuevo diseño ampliado de los gráficos tipo Schoenfeld.

Cultural Interaction in a Passage to India
Authors: Ștefanovici Smaranda 
Published: February 2023

Abstract
The article focuses on cultural interaction from a historical, social, religious, and economic point of view in A Passage to India, book, and film. Can an Englishman and an Indian be friends? Two conflicting cultures, which, through the lens of a holistic approach, will be observed through elements of ethnology, ethnocentrism, human thinking, and behavior. The conclusion of the article will highlight the fact that, despite apparent cultural reconciliation, the characters, both British and Indian, are not ready yet to eradicate the racial tensions and prejudices inherent in both cultures, and hence, are incapable of cultural and human cooperation in a productive way.
Approaching Literature from a Different Methodological Perspective
Authors: Nicolae Cristina 
Published: February 2023

Abstract
Why does literature seem to lose ground among the youths in our country? Does it have to do with the teaching method or with the Internet providing easily accessible and assimilable, ready-to-use information? Is it the teacher the one who bears responsibility or is it the syllabus to blame for the decline in learners’ interest in actually reading (quality) books from cover to cover? Could it be because of the use of technology or the lack of it? The present paper tries to offer some viable answers to these questions (a few out of many) whilst approaching technology-enhanced environment as furthered within the Erasmus+ project ELSE.

Published: February 2023

Abstract
Published in 2012 at Edizioni Culturali Internazionali Genova, Daniela Virdis’s book suggests a novel endeavour, circumscribed to the intersection of the fields of gender and linguistic studies, applied on media studies. The atypical element of the research derives precisely from her choice of discourses submitted to debate, a linguistic and cultural mix as surprising and as ambitious: TV shows (Sex and the City, Desperate Housewives, The Simpsons, Nip/Tuck), film (When Harry Met Sally...) and novel (Bridget Jones’s Diary).
Transparency of Lexemes in the Fundamental Vocabulary
Authors: Rus Maria-Laura 
Published: February 2023

Abstract
We focused in this paper on the transparency of lexemes belonging to the fundamental vocabulary due to different factors: history, etymology, the power of word-formation and compounding, the attribute of expressing fundamental notions etc. This feature of the linguistic sign is relatively seen in the other part of the vocabulary. We analysed this feature comparing a page of prose with a couple of critical fragments referring to that scene.

Published: February 2023

Abstract
Polymers are materials widely used in many important technologies and applications because of their optical, physical, mechanical, thermal and chemical properties. Polyethylene terephthalate (PET) foil is often used as an insulating material in printed electronics, flexible circuitry, displays, industrial applications, graphic films, or for clinical and healthcare applications. A big inconvenience of PET film is the low surface tension which also implies a low wettability, resulting in poor coating adhesion and poor printing properties. In order to eliminate this disadvantage, a surface treatment was used by means of a dielectric barrier discharge (DBD) operating in ambient air at atmospheric pressure which consisted of a high voltage AC source and two circular metal electrodes 60 mm in diameter. The paper aims are to treat two different PET film substrates designed in this work as PET 1, without thermal treatment, and PET 2 which is heat stabilized. The effect of plasma exposure was assessed by determining the water contact angle by means of an Ossila goniometer and by measuring the surface tension with a special ink. The considered foils were exposed to different DBD treatment times (0.2, 0.5, 1, 5, 10, 30 s) and the evolution of the water contact angle overtime after treatment up to 96 hours was monitored. It was found that the water contact angle of the untreated PET 1 and PET 2 was 74° and 73.5°, respectively, and after 30 s DBD treatment time it decreased to 30.9° and 30°, respectively.

Published: February 2023

Abstract

Background Regenerative Medicine (RM) is a branch of medicine that aims to regenerate tissues and organs to overcome the problems transplants entail (poor availability, risk of rejection and intense immunosuppression). To do this, RM makes use of tissue engineering (TE). This fundamental branch deals with creating biological scaffolds capable of performing the role that physiologically belongs to the extracellular matrix (ECM). In this review, we report how specific characteristics of the scaffolds (bio-compatibility, biodegradability and mechanical and conformal properties) can be obtained using 3D printing, which facilitates the emulation of physiological tissues and organs.

Purpose and scope This review reports recent advances in the fabrication method of bioactive scaffolds that can be used clinically, providing support for cell seeding and proliferation. To this end, silk fibroin, tannin and graphene were used to improve the scaffold’s electro-bio-mechanical properties. These materials in different compositions are studied to demonstrate their potential use as bio-ink in bioadhesives and cellularized and implantable 3D-printed scaffolds.

Summary of new synthesis and conclusions reached in the review Silk fibroin is a natural biopolymer; tannin, on the other hand, is a biological polyphenol, highly reactive with other molecules by nature and with promising antioxidant capabilities. Finally, graphene is nothing more than a monolayer of graphite that has been shown to implement the mechanics and electrical conductivity of the compounds in which it is inserted; it also has excellent biocompatibility and surface area, qualities that promote cell adhesion and growth.

Conclusion Polyphenols and graphene have been shown to work in synergy in improving the electro-mechanical properties of silk fibroin scaffolds. We reported optimal and potentially market-competitive bioadhesives, but above all, the proliferation of neuronal precursor cells in vitro was successfully demonstrated.
About the valuation of American option under Black-Scholes model : a numerical study
Authors: Malek R. 
Published: February 2023

Abstract
In the history of option pricing, Black-Scholes model is one of the most significant models. In this paper, we present a new numerical strategy for valuing American option pricing problems governed by Black-Scholes model (BSM). Numerical computations are carried out to show the efficiency and robustness of the proposed method. We compare our numerical solution with the ones based on Finite Element Method (FEM) and the Enriched Finite Element Method (PUFEM). Our result shows the efficiency of the proposed strategy. In addition, that approach can be used to treat nonlinear evolutionary problems.
The determination of virtual source position using convergent anti-trigonometric functions (arcCOS and arcSIN) method for scanning-passive scatter beam in carbon ion therapy
Authors: Ye Yan-Cheng , Zhang Wen-Hua , Wang Jian , Zhang Yan-Shan , Wu Jia-Ming 
Published: February 2023

Abstract

Introduction: We developed a convergent trigonometric functions technique (arcCOS, arcSIN) capable of dealing with the virtual source position delivered by different carbon ion energies from the pattern of scanning-passive scatter beam in this study.

Materials and Methods: A home-made large-format CMOS sensor and Gaf Chromic EBT3 films were used for the virtual source position measurement. The Gaf films were embedded in a self-designed rectangular plastic frame to tighten the films and set up on a treatment couch for irradiation in the air with the film perpendicular to the carbon ion beam at the nominal source-axis-distance (SAD) as well as upstream and downstream from the SAD. The horizontal carbon ion beam with 5 energies at a machine opening field size was carried out in this study. The virtual source position was determined with a convergent arcCOS and arcSIN methods and compared with the linear regression by back-projecting the FWHM to zero at a distance upstream from the various source-film-distance.

Results: The film FWHM measurement error of 0.5 mm (the large-format CMOS detectors was in pixel, a pixel equals 0.5 mm) leads to 1×10-3% deviation of α(cACOS and cASIN) at every assumed virtual source position. The overall uncertainty for the reproducibility of the calculated virtual source position by the assumed t in the vertical and horizontal directions amounts to 0.1%. The errors of calculated virtual source position by assumed t with back projecting FWHM to zero methods were within 1.1 ± 0.001, p = 0.033. The distance of virtual source positions is decreased from SAD with high to low energy.

Conclusion: We have developed a technique capable of dealing with the virtual source position with a convergent arcCOS and arcSIN methods to avoid any manual measurement mistakes in scanning-passive scatter carbon ion beam. The method for investigating the virtual source position in the carbon ion beam in this study can also be used for external electrons and the proton.
