Teachers’ perceptions on the effect of in-service training in Innovative Learning Environments on the implementation of student-centred approaches
Authors: Granda-Piñan Amelia R. , Alameda Villarrubia Alberto , Mengual Andrés Santiago
Published: December 2024

The objective of the study presented in this article was to gather the teachers’ perceptions in relation to the use of student-centred approaches after having received an in-service teacher training under the Innovative Learning Environment umbrella. The instrument used was a questionnaire which was sent, at least three months after finishing the training on the topic, to teachers from the Valencian Community. 152 answers were analysed, obtaining the percentage of teachers who indicated that, after the training, they applied methodologies or strategies which aimed to give more responsibility to students (55,3%, f=84). Evidence on the effect of the characteristics of the training was proved to be significant. More concretely, teachers answered the question positively, in a higher proportion, when they expressed having received various trainings (p=.003), lasting more than 20 hours (p=.008) and including a visit to an innovative learning space (p=.002). Secondly, information about the used methodologies or strategies used was collected. The higher percentages of use were obtained in relation to Project Based Learning (80.3%) and Gamification (45.4%) while the lowest were found in Learning landscapes (7.2%) and Design Thinking (11.2%). Some variations were detected when analysing this according to the stage in which they teach. A correlation study was also developed, in which Flipped Classroom was identified with a weak but consistent correlation with an important number of the other methodologies analysed. As a conclusion, it is highlighted the importance of designing in-service teacher training programs that include a variety of typologies of training (inside the school, outside the school and guided visits), lasting at least 20 hours and offering the opportunity of visiting and experimenting in an innovative learning environment.
Safe, Transparent, and Ethical Artificial Intelligence
Authors: García Peñalvo Francisco José , Alier Marc , Pereira Juanan , Casany Maria Jose
Published: December 2024

The increasing integration of artificial intelligence (AI) into educational environments necessitates a structured framework to ensure its safe and ethical use. A manifesto outlining seven core principles for safe AI in education has been proposed, emphasizing the protection of student data, alignment with institutional strategies, adherence to didactic practices, minimization of errors, comprehensive user interfaces, human oversight, and ethical transparency. These principles are designed to guide the deployment of AI technologies in educational settings, addressing potential risks such as privacy violations, misuse, and over-reliance on technology. Smart Learning Applications (SLApps) are also introduced, integrating AI into the existing institutional technological ecosystem, with special attention to the learning management systems, enabling secure, role-adaptive, and course-specific learning experiences. While large language models like GPT offer transformative potential in education, they also present challenges related to accuracy, ethical use, and pedagogical alignment. To navigate these complexities, a checklist based on the Safe AI in Education principles is recommended, providing educators and institutions with a framework to evaluate AI tools, ensuring they support academic integrity, enhance learning experiences, and uphold ethical standards.

Published: December 2024

The objective of this study is to analyse whether differences exist in the value relevance of intangible assets (IA) and intellectual capital (IC) between firms in the financial sector and other industries. A quantitative approach was adopted. Drawing on the work of Ohlson (1995), an original price model is constructed in the form of a specified panel data model with fixed effects. Data from to 2009-2018, directly collected from primary sources, were used. The sample comprises 52 firms listed on the Argentine capital market without interruption throughout the period. The results show that the value relevance of IA and IC differs between non-financial and financial firms. Among the former, only the human and structural dimensions of IC were of interest to investors. In contrast, both identifiable intangible assets and the three dimensions of IC influence bank valuation, thereby confirming the importance of intangibles in this industry. The study contributes to knowledge of the impact of industry on market valuations of intangibles, which is a somewhat unexplored line of research and, likewise, to knowledge of the banking industry, a sector that has been less well studied in previous research.
Factores externos e impactos sobre la productividad total factores de Empresas de Manufacturas: Evidencia del Caso Peruano
Authors: Tello-Pacheco Mario Delfín
Published: December 2024

En contraste con la literatura sobre la productividad total factorial de empresas, focalizada en factores internos, este trabajo examina el impacto de tres factores externos sobre la tasa de crecimiento de la productividad total factorial (PTF) de empresas manufactureras del Perú, periodo 2002-2019. Usando la Encuesta Económica Anual de firmas manufactureras del Perú, los resultados de las estimaciones de datos de panel con variables instrumentales revelan que países exportadores de productos primarios y derivados de ellos, los términos de intercambio proveen incentivos a las empresas a incrementar la productividad. Contrariamente, shocks domésticos de crecimiento del PBI, en países dependientes de la demanda y producción interna, desincentivan al crecimiento de la PTF dado que la producción interna y PTF se asocian más a los incrementos del capital, en particular aquellos de origen importado. Finalmente, los procesos de liberalización comercial a través de reducciones de los aranceles preferenciales tanto de productos como de insumos ayudan, aunque en menor magnitud y significancia estadística, a incrementar la tasa de crecimiento de las PTF de las empresas, particularmente en las empresas exportadoras.

Published: December 2024

This risk profile identifies and characterises the primary hazards associated with shell eggs and egg products (EEPs) imported into the United Kingdom (UK) from domestic poultry species. The scope includes liquid, dry, cooked, and preserved egg products, excluding composite foods containing eggs or egg products. The document aims to provide essential background information on food safety concerns related to imported EEPs, support the assessment of market access requests for exporting EEPs to the UK, and assist in audit and assurance activities for EEP imports.

A comprehensive literature review and analysis of incident and alert data identified over 100 potential hazards in eggs. Through expert judgement and inclusion criteria, 22 key hazards were shortlisted for characterisation. The microbiological hazards characterised include Campylobacter spp., Listeria monocytogenes, and non-typhoidal Salmonella (Salmonella Enteritidis and Salmonella Typhimurium), with Salmonella Enteritidis being the most frequently reported hazard. Chemical hazards characterised include agricultural contaminants (aflatoxins, ochratoxin A, pyrrolizidine alkaloids), biocides (fipronil, chlorate), environmental contaminants (persistent organic pollutants, melamine, metals), and various pesticides, veterinary medicinal products, and feed additives.

Risk factors for microbiological hazards include hygiene and biosecurity failures, flock age and size, and environmental conditions. Chemical hazards are linked to environmental exposure and misuse of substances. Mitigation measures for microbiological hazards include eradication and vaccination programmes, while chemical hazard mitigation focuses on environmental controls and monitoring programmes. Regulatory measures in Great Britain and Northern Ireland are in place to control both chemical and microbiological hazards in eggs.

This risk profile supports the Department for Environment, Food and Rural Affairs (DEFRA) and the Food Standards Agency (FSA) in ensuring the safety of imported EEPs and guiding market access and audit activities.

This article presents the results that serve as a methodological basis for creating a digital twin of a diesel engine lubrication system. At the first stage, mathematical and computer models have been created for the oil pump of the engine lubrication system. At the second stage, numerical modeling of hydrodynamic processes during pump operation has been carried out in order to verify and validate models based on experimental data. Next, a method of reverse engineering of pump performance characteristics is proposed, and its performance characteristic is constructed. Based on the calculations performed, recommendations have been developed to improve the accuracy of constructing mathematical and computer models of digital twins of a gerotor oil pump. Calculations were carried out for the pump with a modified design.
ESTIMATION OF THE SCREEN MOVEMENT INFLUENCE ON AERODYNAMIC FLOWS IN THE COMBINE HARVESTER CLEANING SYSTEM
Authors:   Scientific and Technical Centre of Combine Harvesters Manufacturing OJSC “Gomselmash”, KALINOUSKI Aliaksandr А.
Published: December 2024

The paper examines aerodynamic modeling of air flows in the cleaning system of a combine harvester. A methodology has been developed for modeling the cleaning system, taking into account the movement of its elements, such as screens and boards, using the Simcenter Amesim and Ansys Fluent software packages. The main stages of the process of aerodynamic modeling of the cleaning system are considered using the example of the combine harvester produced by OJSC “Gomselmash”. A comparative analysis of air flows in a cleaning system with moving elements and when they are fixed in the middle position in a 2D formulation was performed. The results of numerical modeling of the aerodynamics of air flows are presented in the form of numerical values at control points, and the velocity fields and streamlines of the air flow in the flow area are illustrated. The results of the comparative analysis showed that the discrepancy between the speeds and directions of the air flow at the control points is 50 % and 4.5°, respectively. It is concluded that the movements of the cleaning elements during its aerodynamic modeling must be taken into account in order to obtain a real pattern of the air flows in the flow area. The results of modeling with fixed cleaning elements can act as a preliminary calculation to check the adequacy of the model based on the results of experimental measurements in cleaning also with fixed elements. The developed methodology for modeling the aerodynamics of the cleaning flow area will be used in further studies of the cleaning system of the combine harvester to analyze the combined behavior of air flows and heaps.
SOCIO-PSYCHOLOGICAL ASPECTS OF WAR AND THEIR TRANSGENERATIONAL DIMENSION
Authors: Yordanova Kalina
Published: December 2024

This paper is about the psychological effect of war. By the welding of the explanatory potential of psychoanalysis and anthropology, it argues that victims of armed conflict, particularly if protracted, construct a melancholic response (Yordanova, 2018). Often, people on the move are met with hostility by the host countries or may find themselves in the social periphery. This fosters ambivalence towards the new environment as an expression of vulnerabilities. The paper suggests an intergenerational aspect to the above dynamic, too. Children, exposed to violence, lack the emotional and cognitive maturity to grasp what they have lived through. Yet, overwhelmed with their own feelings of loss, their parents fail to help them deal with the trauma. Thus, children identify with the parents’ complicated grief and the assumption of an idealized pre-war past versus scarce future opportunities. Finally, the paper examines the intersections between individual war trauma, cultural memory and power dynamics in post-conflict societies. Using my field work in Sarajevo (2012, 2018), I argue that war survivors avoid the construction of a consistent war narrative in the first person because they need the state-recognized version of history to be re-written (Yordanova, 2015). The ambiguity of their experience in war, the inadequacy of language to convey horror, and the clash of private memories with the official discourse drive them to alternative forms of expression. Survivors and their children use art, humour, tattoos, scarring, and landscape to explain the war and get connected to each other. In the post-war environment, the narrative of veterans who were most exposed to warfare becomes muted in order not to challenge the political status-quo.
Effect of Potassium Optimization on Wheat Drought Tolerance in Controlled Conditions
Authors: Uğurlar Ferhat
Published: December 2024

Wheat (Triticum spp.) is an important cereal crop consumed worldwide, but it is highly susceptible to drought. Potassium plays an essential role in osmotic regulation, photosynthesis, and nitrogen assimilation, all of which are critical for maintaining plant growth and productivity under stress conditions. The aim of this study is to investigate how different potassium levels, including sufficient potassium (SK, 1 mM) and low potassium (LK, 0.05 mM), affect the drought tolerance of wheat during the early stages of seedling development under PEG-induced drought stress. Plant physiological development, canopy temperature, photosynthetic efficiency, antioxidant defense enzymes, and nitrogen assimilation enzymes were assessed in the experiment. In non-drought conditions, LK increased canopy temperature and reduced dry matter yield and photosynthetic performance, with these effects becoming more pronounced under drought stress. SK-treated plants exhibited higher biomass, chlorophyll content, maximum quantum efficiency of photosystem II, and lower canopy temperatures, even under drought conditions. Furthermore, LK restricted the accumulation of key osmotic regulators, including proline, amino acids, and soluble sugars. Under drought stress, LK plants also showed increased hydrogen peroxide and superoxide anion levels, while SK plants had lower reactive oxygen species accumulation and higher antioxidant enzyme activities (catalase and superoxide dismutase). Additionally, LK resulted in reduced activity of nitrogen assimilation enzymes (nitrate reductase, NR, and nitrite reductase, NiR) under both normal and drought conditions. In contrast, SK-treated wheat seedlings maintained higher NR and NiR activities and higher soluble protein content during drought stress. These findings underscore the critical role of potassium management in enhancing wheat yield, particularly in water-scarce regions, as optimal potassium supply strengthens essential physiological and biochemical mechanisms that improve plant tolerance to drought stress.
The Relationship between Investment Horizons and Signals of Insider Trading in Takeover
Authors: Huang Han-Ching , Chen Yong-Yu
Published: December 2024

Abstract

Insider trading in target companies prior to mergers and acquisitions (M&A) can be regarded as an important information about the future profitability of the company. Suk and Wang (2021) find that net purchases by insiders in target companies are positively correlated with abnormal returns at the time of the M&A announcement, M&A synergy, bid premiums, and the probability of M&A completion. Fu et al. (2020) document that long-term investment horizon shareholders can impede insider trading because they can obstruct insiders from using their informational advantages through direct supervision. In this paper, we find that the positive impact of net insider purchases in target companies on abnormal returns at the time of the M&A announcement is stronger in companies with shorter shareholder investment horizons. However, there is no evidence to support that net insider purchases in target companies have a stronger positive impact on M&A synergy in companies with shorter shareholder investment horizons. Furthermore, there is no evidence to indicate that net insider purchases in target companies have an impact on bid premiums, nor that this impact is stronger in companies with shorter shareholder investment horizons. Moreover, we find that the positive impact of net insider purchases in target companies on the probability of M&A completion is stronger in companies with shorter shareholder investment horizons.

Authors: Grancieri Luiza Diniz , Melo Isabela Crisóstomo , Campos Maysa Mendes
Published: December 2024

A saúde e segurança do trabalho (SST) é fundamental para promover a saúde ocupacional e aumentar a eficiência nos ambientes administrativos. Nesse sentido, o estudo objetivou investigar a influência das mudanças ergonômicas na produtividade dos trabalhadores do setor de logística de uma incorporadora. Para isso, foi utilizado o Ciclo PDCA, software Ergolândia para análise ergonômica do trabalho com os métodos RULA e Checklist OCRA e software Flexsim para simular e comparar a produtividade pré e pós-implementação das melhorias ergonômicas. Os resultados revelaram uma redução inicial de 9,25% na produtividade após a implementação das medidas ergonômicas, explicado pelo tempo de acomodação do novo processo. No entanto, foram observadas melhorias significativas na saúde física e mental dos trabalhadores, o que pode impactar positivamente a motivação e o comprometimento da equipe. Quanto às limitações do trabalho, pode ser verificada a coleta de tempos pós melhoria imediatamente após mudanças ergonômicas, tempo insuficiente para adaptação dos trabalhadores. Estudos futuros podem replicar a metodologia apresentada em diversos postos administrativos para comparar eficácia de intervenções ergonômicas.

A Study of the Relationship Between Servant Leadership, Micro-Aggression and Intention to Leave in IT Sector: Employee Resilience as Mediating Variable
Authors: bin Ramlan Mohamed Nazhif , Nisak Ahmad Nursaadatun , Mohamed Razali Murni Zarina
Published: December 2024

In Malaysia’s rapidly evolving Information Technology (IT) industry, marked by increasing cyber threats and a scarcity of skilled cybersecurity professionals, this study explores the intention to leave among IT professionals. At the intersection of servant leadership, microaggressions, and employee resilience, it aims to unravel these factors’ relationships and their collective impact on turnover intentions. Emphasizing the lack of studies on race- based microaggressions, particular attention is given to microaggressions as workplace adversity. The research examines servant leadership, microaggressions, and employee resilience, focusing on cybersecurity companies in the Klang Valley region, capturing IT industry dynamics in Malaysia. Using Partial Least Square – Structural Equation Modeling (PLS-SEM), survey data from 385 IT professionals in Klang Valley was analyzed, revealing significant relationships: a positive relationship between servant leadership and employee resilience, a negative relationship between employee resilience and intention to leave, a negative relationship between servant leadership and intention to leave, and a positive link between microaggressions and intention to leave. Additionally, employee resilience was found to complementarily mediate the relationship between servant leadership and intention to leave. However, the hypothesized negative relationship between microaggressions and employee resilience, and the mediation effect of employee resilience between microaggressions and intention to leave, were not supported. The study also utilized PLS Predict to show that the variables can predict future research outcomes. Theoretically, this study enriches understanding by affirming servant leadership’s significance in explaining the nexus between employee resilience and intention to leave. Practically, by unraveling these associations, the research aims to provide organizations with insights to mitigate high turnover rates, potentially reducing hiring costs, training expenses, and overall operational outlays in the IT industry.

Aikuisoppijoiden tunteet suomen kielen reaaliaikaisessa etäopetuksessa
Authors: Scotson Mia
Published: December 2024

Tässä artikkelissa tutkin aikuisoppijoiden tunteita suomen kielen reaaliaikaisessa eli synkronoidussa etäopetuksessa. Tarkastelen, millaisia tunteita ja kuinka usein oppijat kokivat suomen kielen etäopetuksessa sekä millaisissa tilanteissa ja mistä syistä oppijat kokivat erilaisia tunteita. Hyödynnän tutkimuksessa Pekrunin (2016, 2018) kontrolliarvoteoriaa. Aineisto koostuu verkkokyselystä (n = 104), jonka analysoin sisällönanalyysin avulla. Tulosten perusteella suomen kielen aikuisoppijat kokivat reaaliaikaisessa etäopetuksessa huomattavasti useammin myönteisiä kuin kielteisiä tunteita: 94 prosenttia vastaajista kertoi tuntevansa iloa ainakin kerran viikossa, kun taas ahdistusta tunsi viikoittain 23 prosenttia vastaajista. Eniten sekä positiivisia että negatiivisia tunteita aiheuttivat oppijaan itseensä kohdistuvat seikat kuten oma oppiminen, asioiden ymmärtäminen ja oman oppimisprosessin eteneminen. Vastausten perusteella yksi merkittävä kielenoppijan toimijuutta rajoittava ja pääasiassa ikävystymistä aiheuttava tekijä oli oppijan fyysinen olotila kuten väsymys, joka johtui usein suomen opiskelusta töiden ohessa. Opettajan olemuksella, toiminnalla ja pedagogisilla valinnoilla oli merkittävä vaikutus oppijoiden kokemiin tunteisiin. Opettajan ystävällisyys oli erittäin tärkeää positiivisten tunteiden edistämisen kannalta, ja negatiivisia tunteita puolestaan aiheuttivat esimerkiksi opettajan pitkät yksinpuhelut. Teknologisen oppimisympäristön näkökulmasta iloa ja onnea tuottivat verkossa sijaitsevat pelipohjaiset oppimisympäristöt, kun taas etäopetuksen tekniset ongelmat synnyttivät ahdistusta, ikävystymistä ja turhautumista. Tärkeä myönteisten tunteiden lähde oli vuorovaikutus toimijoiden välillä ja erityisesti breakout-huoneissa tapahtuva pienryhmätyöskentely, joka mahdollisti opiskelijoiden tutustumisen toisiinsa, puhumisen harjoittelemisen, vertaisoppimisen, yhteenkuuluvuuden tunteen sekä osallisuuden kokemuksen.
Suomalaista viittomakieltä käyttävien kuurojen ja huonokuuloisten nuorten mediankäyttö ja mediaympäristöt sosiaalisina ja kulttuurisina käytänteinä
Authors: Sivunen Ulla
Published: December 2024

Tarkastelen artikkelissani 25:n suomalaisen viittomakieltä (SVK) käyttävän 13–28- vuotiaan kuuron ja huonokuuloisen (KHK) nuoren median käyttöä ja tekstikäytänteitä digitaalisissa ympäristöissä sosiaalisina ja kulttuurisina käytänteinä. Lähestyn aihetta ensisijaisesti sosiokulttuurisen tekstitaitoperinteen (Uudet lukutaidot, New Literacy Studies, NLS) näkökulmista. Tutkimuskysymykset ovat: Mitä medioita ja mihin tarkoituksiin KHK-nuoret käyttävät niitä? Millaisiin käyttäjäryhmiin nuoret ovat jaoteltavissa? Tulokset osoittavat, että KHK-nuoret ovat mediankäytöltään ja monilukutaidoiltaan heterogeeninen ryhmä, jossa ilmenee kielellisiä, kulttuurisia ja yksilöllisiä eroja. KHK-nuoret ovat jaettavissa mediankäyttö- ja lukutavoiltaan kolmeen ryhmään: 1) visuaalinen ja viitottujen kielten lukija, 2) monikielinen lukija ja 3) puhuttujen kielten lukija. Näiden ryhmien piirteitä voidaan tarkastella kieli- ja lukutaitojatkumolla, joiden päissä painottuvat eri kielet ja modaliteetit. KHK-nuoret lukevat media-arjessaan useita erikielisiä tekstejä monenlaisissa digitaalisissa ympäristöissä. SVK:n lisäksi he lukevat ja viittovat usein muitakin viitottuja kieliä ja kansainvälistä viittomista (International Sign). Mediaympäristöjen saavutettavuus, viittomakielisten tekstien ja ympäristöjen saatavuus sekä KHK-nuoren kieliin, kulttuuriin ja kuulostatukseen kytköksissä oleva lukijaprofiili ovat vuorovaikutteisessa suhteessa ja vaikuttavat myös nuoren toiminnan mahdollisuuksiin. Kotimaisen rajallisen viittomakielisen mediatarjonnan vuoksi KHK-nuoret lukevat usein ulkomaisia viitottuja mediasisältöjä, useimmiten kansainvälisellä viittomisella tai amerikkalaisella viittomakielellä. Tekstitys koetaan tärkeänä osana erityisesti audiovisuaalisissa mediasisällöissä, mutta sen tarjoamat hyödyt puhutuissa sisällöissä eivät ulotu kaikkiin KHK-nuorten lukijaryhmiin. Tekstitys koetaan tärkeänä myös viittomakielisissä mediasisällöissä, sillä KHK-nuorten SVK-lukutaito ei aina ole riittävä tavanomaisella sujuvuudella tuotettujen viittomakielisten mediatekstien lukemiseen eri aihepiireistä, ja myös suomenkieliset tekstit tuottavat osalle KHK-nuorista vaikeuksia. Mahdollisuudet monilukutaitojen oppimiselle eivät siten Suomessa jakaudu tasaisesti.
Wetlands in Peril: How Agriculture Damages Critical Ecosystems, Increasing Flood Risk in the Upper Midwest
Authors: Woods Stacy
Published: December 2024

Industrial agriculture degrades and destroys wetlands. Changes to the Clean Water Act in 2023 rolled back wetlands protections, further increasing risks to wetlands from corporate agribusiness. The destruction of wetlands disrupts biodiversity, threatens fishing and farming, deteriorates water quality, and compromises climate resilience. Wetland degradation also erodes critical flooding defenses. Amid the Upper Midwest’s intensive agricultural landscape, 30 million acres of wetlands provide nearly $23 billion in annual residential flood mitigation benefits. Over the long term, protecting these wetlands could prevent between $323 billion and $754 billion in flood damages in this region. These benefits are especially crucial for traditionally marginalized and overburdened communities that encounter high flood risks and face significant challenges in recovering from severe flooding. The next farm bill offers a pivotal opportunity to address the devastating damage industrial agriculture inflicts on wetlands and to support conservation efforts that protect and restore these essential ecosystems.

Published: December 2024

O trabalho objetiva analisar a figura dos smart contracts na perspectiva do princípio da obrigatoriedade dos contratos, de maneira que possa ser determinada uma potencial ressignificação do “pacta sunt servanda” diante deles. Assim, busca conceituar e categorizar a blockchain e os contratos inteligentes para um exame de seus efeitos diante do Direito e o modelo do contrato tradicional. Por conseguinte, é realizada uma breve contextualização histórica da força obrigatória dos contratos, apontando suas concepções na história, analisando-o no contexto do meio digital. Considerando-se essa análise, são sistematizadas suas aplicabilidades em nível global e, posteriormente, na realidade brasileira – de modo a apresentar as possíveis vantagens e desvantagens do instituto. Adota-se na pesquisa a metodologia referencial bibliográfica, utilizando artigos, livros e obras que se reportam ao tema, assim como a legislação brasileira. Diante da pesquisa, conclui-se que o smart contract é uma opção com capacidade de reduzir os custos de transação e alguns riscos inerentes às operações. No entanto, devido às limitações da lógica de programação, seria uma opção viável para contratos mais simples e nichos específicos. Ademais, pode ser vantajoso aos entes públicos, no âmbito de sua própria rede Blockchain e, ainda, em face à possível utilização da moeda digital.
Primary vaginal melanoma: a rare entity. A case report and literature review
Authors: Benabdelhafid Zohir
Published: December 2024

Primary vaginal melanoma is rare, aggressive, and has a poor prognosis. It represents less than 1% of all melanomas in women, less than 10% of all melanomas of the female genital tract, and 3% of all vaginal malignancies. It primarily affects postmenopausal women between 60 and 80 years. Abnormal vaginal bleeding is the most common symptom, and the precise diagnosis is clinical and histopathological.
The appropriate treatment for vaginal melanoma is poorly defined. Despite the different types of proposed treatments, prognosis remains poor.

Authors: IDDIR Samir
Published: December 2024

Objective. To describe the population of children with post-COVID-19 multisystem
inflammatory syndrome (MIS-C), and to analyze their epidemiological, clinical,
therapeutic, and evolutionary profile. Materials and methods. This is a prospective
descriptive cohort study of post-COVID-19 multisystem inflammatory syndrome (MISC) diagnosed at the Tizi-Ouzou University Hospital. Results. We were able to collect
49 cases, with a peak age range of 2 to 6 years. Sex ratio (M/F) was 1.45. Fever was
noted in 100% of cases, mucocutaneous signs were observed in 79.6% of cases.
Gastrointestinal symptoms in 73.4% of cases. Myocarditis was present in 38.8%. All
patients presented with an inflammatory syndrome. The coagulation profile was
abnormal in 64.3% of patients. Liver function tests were abnormal in 28.6% of cases.
Troponins were elevated in 35% of cases. Other laboratory tests were negative.
Proof of COVID-19 infection was established in all patients. Apyrexia was observed
after administration of immunoglobulins (IGIV) and corticosteroids in 58.33% of
cases, with a progressive improvement in general condition and inflammatory profile
(CRP). Conclusion. The exact incidence of MIS-C is currently unknown, but is likely
low. The underlying pathophysiological mechanisms of the disease remain to be
determined. While the prognosis under anti-inflammatory treatment appears to be
good, the long-term prognosis remains unclear.
Outcomes of the First 46 patients underwent Endothelial Keratoplasty in Algeria: 4 years follow- up
Authors: Leboukhe Saad
Published: December 2024

Background of the Study. The purpose of this study is to assess indications,
refractive outcomes, endothelium cell density (ECD), graft survival, and complications
related to the first 46 cases of Descemet’s Stripping Automated Endothelial
Keratoplasty (DSAEK) and deep membrane endothelial keratoplasty (DMEK)
achieved in Algeria. Setting. Department of ophthalmology, military university hospital
of Constantine, Algeria. Material and Methods. In this retrospective study, 46 patients
were enrolled between December 2016 and December 2019. A pre-and post-operative
complete ophthalmologic examination was done. The data were collected on
demographic characteristics, pathology, best corrected visual acuity (BSCVA), postoperative astigmatism, central thickness of the graft measured using OCT. the
endothelium cells density was checked at 1 year, 3 years, and 4 years. Results. The
results obtained after having analyzed the data demonstrate that mean age is 71.95 ±
10.16 years. Females represent 47.9% of the sample of our research, while males
represent 52.1%. Results show that the endothelial dysfunction was secondary to:
cataract surgery in 86.9% of cases, graft failure in 13%, Fuchs’ dystrophy in 2.2%, and
myopic Artisan IOL in 2.2%. DSAEK was performed in 84.50% of cases, DMEK in
15.50%, and Combined surgery in 15.20 %. The mean of BSCVA in log Mar at 1, 3
and 4 years was 0.62 ± 0.22, 0.39 ± 0.28 and 0.37 ± 0.25, respectively. Endothelial
cell loss was in 1, 3 and 4 years: 41.18% ,43.46%, and 52.32%, respectively. Graft
survival was 93.47 % at 1 year, 87% at 3 years and 77.78% at 4 years. Graft
detachment occurred in 5 cases, 3 attached successfully after rebubbling.
Conclusion. Endothelial keratoplasty is becoming the gold standard for surgical
treatment of corneal endothelium dysfunction without important stromal scars. This
procedure allows short period of recovery, rapid visual rehabilitation with low
astigmatism and less complications comparing to PK.

Authors: DJEBAILI Rachida
Published: December 2024

Background. COPD patients’ quality of life (QOL) assessment allows a global
evaluation of disease’s impact perceived by patients in different conceptual domains
of life and state of well-being. However, the measurement remains subjective and is
done by a validated QOL scales. The purpose of our study is to evaluate the impact
of COPD on the QOL of patients and to address factors contributing to deteriorate their
QOL. Patients and methods. A descriptive study included COPD patients in stable
condition to assess their quality of life by VQ-11 Scale. Only those who agreed to
participate and respond to the questionnaire were included, and anonymity was
guaranteed. The questionnaire was completed by a pneumologist due to the low level
of patients’ education, translating the questions into the Algerian dialect each time and
making sure that questions were well understood by patients. In addition, we assessed
respiratory symptoms such as cough and dyspnoea using the Modified Medical
Research Council (m MRC) scale. Number of exacerbations in the previous year, with
or without admissions was also noted. Results. 195 COPD patients were enrolled,
185 men and 10 women; age 67 (± 10), smoking 45 (± 15) packs/year, FEV1: 48 (±
23) %. The results of the VQ-11 questionnaire showed that the quality of life of our
COPD patients was impaired in 78.14% of cases; mainly affecting impairment of the
functional component (76.92%), psychological and relational scores were also
impaired in 57.94% and 42.05% of cases, respectively. Factors associated with an
impaired quality of life score in our series were: age greater than 60 years (80%),
severe bronchial obstruction in 56% of cases, frequency of respiratory symptoms:
cough and stage 2 dyspnea , mMRC in 85% and 69% of patients respectively and
occurrence of exacerbations in 67.15% of cases. Conclusion. The impact of Chronic
obstructive pulmonary disease (COPD) on patients' quality of life has been well
established and it’s recommended that it will be evaluated systematically in routine
practice.

Medicinal plants have been recognized as valuable source of natural antibacterial compounds and alternative agent for the treatment of bacterial infections. This study was carried out to determine the phytochemical properties, antibacterial activity and biochemical compounds of the crude extracts of Acacia nilotica. The reflux extraction, qualitative phytochemical screening, agar well diffusion and gas chromatography mass spectrometry (GC-MS) method was used. Phytochemical screening indicates the presence of phytochemicals such as alkaloids, tannins, saponins, phenols, sterols, terpenoids and flavonoids. Ethyl acetate and aqueous extracts were the most active with mean inhibition zone (MIZ) diameter of 20.00±0.00mm and 14.67±1.16mm against B. cereus and P. aeruginosa respectively while the MIZ of the fractions (22.00±1.53mm) were higher at 50mg/mL as compared to the positive control with MIZ of 17.00±0.00 (p<0.05). the lowest minimum inhibitory concentration (MIC) and minimum bactericidal concentration MBC of 15.6mg/mL and 31.3mg/mL were obtained against P. aeruginosa. Compounds identified in the most active fractions with higher peaks include Oleic Acid (24.43%), n-Hexadecanoic acid (22.96%) and Tetradecanetetrol (19.25%) which are reported to possessing antibacterial activity. Based on the result of this study, it can be concluded that extract from Acacia nilotica possess antibacterial activity and can be considered for drug development against the test organisms.

Published: December 2024

Esta investigación analizó el impacto de la tutoría en el rendimiento académico de los estudiantes universitarios mediante una revisión integradora de
la literatura en las bases de datos Scopus y WoS. El estudio está enmarcado
dentro del método formulado por Mendes et al. (2008) mientras que el proceso de búsqueda siguió el flujograma Prisma. Entre los resultados alcanzados,
la revisión de 20 artículos mostró que el 40 % carecía de un fundamento teórico que respaldara el estudio; asimismo, el 65 % de los documentos presentaron un enfoque cuantitativo, el 60 % fueron publicados en inglés y el 55 %
se publicaron en revistas indexadas en Scopus. El análisis de cada artículo
evidenció tres categorías principales en la literatura: modelos de tutoría, tutoría de estudiantes universitarios e impacto de la tutoría en el rendimiento
académico. Se concluyó que la tutoría tiene un impacto significativo en el
rendimiento académico de los estudiantes, ya que permite el diagnóstico y seguimiento de las dificultades académicas de manera personalizada y grupal.
Para lograrlo, se requiere la formación en labores tutoriales, la claridad en las
funciones del tutor y el establecimiento de la colaboración como estrategia
para las prácticas de tutoría entre docentes y estudiantes.
