Assessment of the Quality of the Training System in Moroccan Higher Education Institutions: Case of the Sciences ans Techniques of Physical and Sports Activities.
Authors: ESSAOUDI MOHAMED , LOTFI RAJA 
Published: April 2021

Purpose: The aim of our study is to assess the overall quality of the university training system in sciences and techniques of physical and sports activities in Moroccan higher education. Method: Our method was based on a quantitative, exploratory and correlational approach. The independant variable (the quality of services provided by the UTS in STPSA) and the dependant variable (overall student satisfaction) were investigated emprically and statically. 256 students from 5 STPSA institutions of higher education were surveyed. Two measurement tools were used: an adapted version of the SERVQUAL instrument and a validated questionnaire of satisfaction with the TS-STPSA domains. The internal consistency of the two measuement tools was tested and confirmed. Similarly, the inter-dimensional correlation matrix was examined to verify the statistical reliability of our tools and their appropriateness to the STPSA context. Results: The overall quality of training services was perceived by 59% of students as unsatisfactory. "Empathy" is the strongest determinant of TS quality in STPASA. While "Responsiveness" is the weakest dimension. The two dimensions of "Reliability" and " Assurance" reinforce students' dissatisfaction with the STPSA major with negative gaps of -1.42 and -137 respectively. While "Tangibility" is the most neutral dimension with almost no difference. These five dimensions explain 45.7% of the variation in overall student satisfaction. They have a positive effect on the satisfaction of students' STPSA. The correlation examination, between the dimensions of service quality and satisfaction with the STPSA-TS domains, revealed seven positively significant relationships, including three between students' "Overall Satisfaction" and the dimensions of "Tangibility", "Responsiveness" and "Empathy". Conclusion: Globally, the quality of TS in Moroccan STPSA is unsatisfactory. The students' expectations greatly exceed their perception of the effective quality of the TS. This suggest that STPSA fields are not effectively fulfilling the students' initial expectations. This judgement is characterized by "negative" quality gaps in three of the five dimensions of the SERVQUAL scale (Responsiveness, Reliability and Assurance). The produced outcomes remain referential to allow STPSA managers to improve the quality of their services. However, students' expectations and perceptions are subjective and rarely stable over time. They vary according to several variable factors (mood, emotion, stress, motivation...). A longitudinal study could be conducted later to overcome or mitigate these limitations.
Exam preparation strategies and concerns of university students: gender and open access vs regulated system effects
Authors: Zerdani Ilham , LOTFI Said 
Published: April 2021

The purpose of this study is to identify test preparation strategies and concerns of university students in the open and regulated education system. We surveyed 294 students (55.10% male, 44.90% female), 60.54% from the open access system, and 39. 46% from the regulated access system, four dimensions are measured: students' and parents' concerns about university education, constraints to effective academic performance, exam preparation strategies and factors affecting academic performance.
The results show three main student concerns in both training systems: self-development, seeking new learning (84.35%) and graduation (73.13%). On the other hand, about half of the students (49.32%) feel that their parents are preoccupied with their studies and are stressed or bothered (31.29%) by their incessant advice. We have identified 15 types of difficulties that are sources of constraint on the efficiency of university student performance, grouped into three categories: cognitive difficulties (32.64%), teaching methods difficulties (30.57%) and organization difficulties of the training program (36.79%). One-fifth of students review every day, every course, and thus spend an average of half an hour to an hour (41%) per review day. However, female students spent significantly more time per day (+3 hours, p<.038) on course revision than their male colleagues. Analysis of students' exam preparation programs shows six preparation strategies, dominated by the reading method (28.90%) and course outlines (26.30%). In both training systems, half of the students were dissatisfied (52.38%) with their personal preparation methods, of which 71.22% were female students. These students also perceive that their exam review strategies are little or not effective (56.46%) of which 40.22% are female students significantly different from their male counterparts (p<.05). The majority of students (61.88%) in both training systems do not place importance on all training modules. This finding is more pronounced for males than females (40.51% vs 21.27%, p<.008, respectively), and higher in the OSA than in the RAS (46.41%, 15.47%, p<.008, respectively). The bivariate correlation analysis shows significantly positive coefficients between 1st and 2nd year university results year university (r = .428, p<, 000), and baccalaureate 's marks (r = .255, p<.019). We also identified five factors responsible for poor school grades. It is necessary to introduce cognitive and mental preparation approaches for students into the pedagogical system of university teaching and supervision in order to optimize the performance of students' results.

Rupturas conceituais de segurança e meio ambiente no Antropoceno: os nexos securitários em formação desde o pós-guerra fria
Authors: Andrade Júnior Hermes , Brandão Ana Paula 
Published: April 2021

O modelo do Antropoceno refere-se às perturbações na superfície terrestre causadas pela intensa atividade humana. Estando associado a um novo intervalo na história geológica da Terra, ele tem sido abordado por diversas áreas de conhecimento das chamadas ciencias da Terra, chegando agora até às ciencias sociais e humanidades, desde a sua implantação. As Relações Internacionais (RI) procuram uma melhor especificidade de suas funções diante do Antropoceno, alargando seu campo de atuação. No campo da Segurança, afirma-se que os atores estejam mais conectados e comprometidos entre si e que o significado de Segurança baseado no ator estatal e nos setores político e militar não faz mais sentido no modelo antropocênico e que a transdisciplinaridade (para a disciplina de relações internacionais e além dela) deva ser afirmada. Colaborando com um manifesto lançado em conferencia patrocinada pela Revista Millenium, da London School of Economics trazemos o corte temporal do pós-Guerra Fria para alargar o debate sócio-ambiental em termos transdisciplinares ao campo dos estudos de segurança. O Antropoceno prenuncia uma época de insegurança. Embora a atenção à segurança como ameaça tenha crescido nas últimas duas décadas em um franco estímulo ao debate do pós-Guerra Fria e a securitização seja visível no sistema global, persiste um grande número de nexos de segurança em construção transdisciplinar que merecem reexame crítico diante do fenômeno da degradação ambiental criada dentro do Antropoceno conceitual, que preconiza uma ameaça bipolar humano-natureza.

Zanesljivost preiskav, ki se izvajajo pred operacijo, za načrtovanje zdravljenja raka endometrija v UKC Ljubljana
Authors: Jakopič Maček Katja , Krajec Maja , Verdenik Ivan 
Published: April 2021

Izhodišča: Slovenska priporočila za obravnavo bolnic z rakom endometrija svetujejo različen obseg preiskav za kirurško oceno o napredovanju bolezni glede dileme, ali ob standardni odstranitvi maternice s priveski opustiti limfadenktomijo oz. opraviti zgolj biopsijo varovalne bezgavke, ali pa opraviti kompletno pelvično in paraaortno limfadenektomijo glede na stopnjo tveganja za širjenje bolezni zunaj maternice. Bolnice razvrstimo v različne skupine glede tveganja na podlagi histološkega gradusa po biopsiji maternice ter glede na slikovno oceno razširjenosti bolezni (magnetno resonančno slikanje ali ekspertna ultrazvočna preiskava). V Univerzitetnem kliničnem centru Ljubljana smo leta 2015 uvedli ekspertno ultrazvočno preiskavo (TVUZ) za oceno razširjenosti rakavih bolezni. Naš namen je bil oceniti zanesljivost preiskav, ki jih opravimo ob diagnozi raka endometrija v UKC Ljubljana pred operacijo.
Metode: Pregledali smo dokumentacijo 79 bolnic s histološko potrjenim rakom endometrija, ki so opravile TVUZ od januarja 2016 do septembra 2017. Histološko diagnozo pred posegom in oceno razrasta (invazije) s TVUZ v miometrij in stromo materničnega vratu smo primerjali s končnim histološkim izvidom.
Rezultati: Ultrazvočna ocena razrasta (invazije) raka v miometrij je imela 76 % (95 % IZ, 58 – 89 %) občutljivost in 81 % (95 % IZ, 67 – 91 %) specifičnost. Ultrazvočna ocena razrasta raka (invazije) v stromo materničnega vratu je imela 54,5 % (95 % IZ, 23 – 83 %) občutljivost in 75 % (95 % IZ, 63 – 85 %) specifičnost. Ocena histološke stopnje diferenciacije je bila po operaciji višja (angl. upgrading) v 11,3 %, nižja (angl. downgrading) pa v 7,5 %. Ocena ujemanja preiskav pred operacijo z dokončnim izvidom z uporabo koeficienta kappa je bila za histopatološko preiskavo 0,699, za razrast v miometrij 0,564 in za razrast v stromo materničnega vratu 0,203. Ena bolnica je prestala na osnovi izvidov pred operacijo preobsežno zamejitveno operacijo; ostale pa so bile ustrezno kirurško obravnavane.
Zaključki: Kot najbolj zanesljiva se je izkazala patohistološka preiskava, sledi ji ultrazvočna ocena razrasta (invazije) v miometrij, medtem ko je bila ultrazvočna ocena razrasta (invazije) v stromo materničnega vratu manj zanesljiva.

Authors: Gupta Rahul Kumar , Rathi Renu Bharat 
Published: April 2021

Background: In the last few decades, plants have been playing a vital role in treating cancer and infectious diseases. Natural products have been rediscovered as effective methods of drug production amid advances in combinatorial chemistry. Roots of Martynia annua are being used as a folklore remedy for the treatment of cancer and rheumatism successfully.
Aims of the Study: In the present study, ethanolic, aqueous and hydro-ethanolic root extracts of Martynia annua were screened for in vitro cytotoxicity activity using different cell lines.
Settings and Design: In the experiment, lung cancer cell lines (A549), leukemia cancer cell lines (K562), oral cancer cell lines (SCC-40), breast cancer cell lines (MCF-7) & cervix cancer cell lines (SiHa) were studied on the extracts.
Materials and Methods: The method used was Sulforhodamine B (SRB) assay technique in which growth inhibition of 50% (GI50) was analyzed by comparing it with standard drug Adriamycin (ADR) (doxorubicin).
Results: Aqueous & ethanolic extract of Martynia annua root had shown high anticancer activity with GI50 value 11.3µg/ml and 20.4µg/ml respectively on human leukemia cell line K-562 but for human breast cancer cell line MCF-7, human lung cancer cell line A-549, human squamous cell carcinoma SCC-40 and human cervical cancer cell line SiHa the extracts showed activity in more than 80µg/ml.
Conclusion: The anticancer activity of aqueous extract of Martynia annua root was found superior than the ethanolic extract in Human Leukemia Cell Line K-562. The study indicates that the Martynia annua root extracts are most effective against the fast proliferative cells (Leukemic cells) and possibly a cell cycle arrest (needed to be proved as future perspective) is the mode of action of the extract. To study its effect on targeted cancers, specific in vivo scientific studies and clinical trials should be carried out by further researchers.

Published: April 2021

AbstractAll‐solid‐state sodium (Na) batteries (ASSSBs) using sulfide‐based solid electrolytes (SEs) have attracted intensive attention due to their superior safety, high energy density, and low cost. However, the interfacial issue is one of the biggest challenges to achieve high‐performance sulfide‐based ASSSBs due to the serious reactions between active Na metal and sulfide SEs at the interface. To address the interfacial challenges, a simple and efficient approach by introducing a phase transition polymer electrolyte as an interlayer to stabilize the interface is proposed. Na3SbS4 as a model sulfide SE is used to demonstrate the interlayer strategy to stabilize the interface by preventing the detrimental reactions and inhibiting Na dendrites. As a result, stable Na plating/stripping is observed in Na symmetric cells under the current density of 0.1 mA cm−2. Moreover, ASSSBs with Na metal and TiS2 electrode deliver long‐term stability over 300 cycles remaining a specific capacity above 100 mAh g−1, and FeS2||Na cells exhibit an impressive specific capacity of up to 200 mAh g−1 after the 20th cycles. This study demonstrates an efficient strategy to address interfacial challenges between sulfide SEs and Na metal, which contributes to the development of ASSSBs in next‐generation energy storage systems.
A Universal In Situ Cross‐Linking Strategy Enables Orthogonal Processing of Full‐Color Organic Microlaser Arrays

Published: April 2021

AbstractLarge‐scale red, green, and blue (RGB) microlaser arrays capable of exhibiting full‐color laser emissions are urgently desired for high‐performance flat‐panel laser displays. With excellent solution processability and optoelectronic properties, organic materials are promising candidates for full‐color microlasers; however, the heterogeneous integration of full‐color microlasers remains a challenge due to their poor solution stability to withstand multistage solution processing. Here, a robust in situ cross‐linking strategy is proposed to enable orthogonal processing of organic microlasers to heterogeneously integrate large‐scale full‐color organic microlaser arrays. The organic microlasers with controlled physical dimensions and spatial locations are fabricated with an electron beam (e‐beam) induced in situ polymerization reaction. Profiting from enhanced orthogonality of microlasers, large‐scale pixelated RGB microlaser arrays are monolithically integrated through successive e‐beam patterning processes. Laser emissions in the RGB microlaser pixels cover a color gamut 41% larger than the standard RGB space, with which flexible full‐color organic laser display patterns with a resolution of 254 dpi on a centimeter scale is obtained. The scalable heterogeneous integration platform reported in this work will pave a new avenue for the efficient construction of large‐scale high‐performance organic integrated optoelectronic devices.
Refocusing the Immune Response to Selected Epitopes on a Zika Virus Protein Antigen by Nanopatterning

Published: April 2021

AbstractInfections with Zika virus (ZIKV) are linked to the development of severe central nervous system disorders, but the need for a ZIKV vaccine remains unmet. Although the design of vaccines that elicit antibodies targeting domain III (DIII) of the ZIKV envelope (E) protein as an antigen is an attractive strategy, poorly neutralizing or cross‐reactive antibodies that target the E protein may lead to antibody‐dependent enhancement of disease. It is therefore decided to use the previously reported nanopatterning technique, which combines the site‐specific incorporation of non‐canonical amino acids with site‐specific functionalization of the protein with polyethylene glycol (PEG), to shield selected epitopes on DIII. Two different nanopatterned DIII variants are designed and characterized and demonstrate that epitope shielding with PEG completely inhibits the binding of epitope‐specific antibodies in vitro. Furthermore, immunization with multivalent nanopatterned DIII antigens results in the refocusing of the antibody response toward the exposed epitopes on the protein surface and away from potentially enhancing epitopes. This ability to redirect the antibody response toward targeted regions of the DIII protein should be useful for the design of effective and safe ZIKV vaccines.
