The process of transforming young students into competent medical graduates is a challenging one, wherein as teachers, we have to adopt a combination of innovative and traditional teaching-learning approaches to meet the needs of different types of learners. In the current era, the majority of teachers and medical students has access to the Internet and use smartphones. Instagram is a social media application that provides a platform for users to share image-based or video-based information. The findings of studies have revealed that the application has been utilized by teachers to share images dealing with infectious diseases and radio-diagnosis, and this, in turn, inculcates clinical reasoning and critical thinking skills. To conclude, the utility and reach of social media applications, including Instagram, are increasing among medical students each day. The need of the hour is to acknowledge the scope of the same and use the same for the benefit of students either in the form of passing specific information or through a structured curriculum to ensure attainment of the learning outcomes.

Context and objective. The sperm tests explore testicular spermatogenesis, epididymal maturation and storage, prostate and seminal vesicle secretions and genital tract patency. The aim of this study was to establish a correlation between spermogram abnormalities and epididymalvesicular biomarkers of spouses in infertile couples. Methods. An analytical cross-sectional study was conducted from November 15, 2020 to October 15, 2021 at the Centre Universitaire de Diagnostic du Graben in Butembo, DRCongo. The correlation between spermogram abnormalities and epididymal biomarkers was investigated by determining the Pearson correlation coefficient. Results. One hundred ninety-two patients were involved. The alphaglucosidase concentration was low in 31.2 % of cases of altered spermograms against 7.3 % of the spouses with normal spermograms. The fructose concentration was also low in 37.5 % of cases of altered spermograms against 4.2% of normal spermograms. Semen volume was associated with reduced fructose concentration while sperm concentration, motility, vitality and morphology were correlated with reduced alphaglucosidase levels. Chlamydia (OR: 13.7), Gonorrhoea (OR: 3.8), anti-sperm antibody serology (OR: 6.05), history of STI (OR: 3.61), smoking (OR: 5.62), leukocytospermia (OR: 6.23) as well as varicocele and obesity were significantly correlated with spermogram abnormalities. The latter were dominated by oligoasthenoteratozoospermia (39.6%) and consisted of various types of abnormalities including azoospermia (15.6 %). Conclusion. The functional status of the epididymo-vesicular and genital tract influences semen quality. Genitou-inary tract infections, even if asymptomatic, are the major etiological factor of infertility. The topographical diagnosis requires the contribution of sperm biochemical markers for a judicious therapeutic approach.
Teaching Ancient Egyptian Philosophy of Education in Teacher Education
Authors: Sesanti Simphiwe
Published: September 2022

In 2003, almost a decade after South Africa’s 1994 first democratic elections, an academic debate emerged about the need to include the indigenous African philosophy of education in teacher education. Subsequently, Ubuntu philosophy has been given attention in philosophy for teacher education. However, ancient Egyptian philosophy of education, an indigenous African tradition, is absent. On their part, European and Asian philosophies of education are centred, leaving space for some philosophers of education to falsely attribute the genesis of philosophy, in general, and philosophy of education, in particular, to Europe and Asia since the two are dated. In contrast, Ubuntu philosophy of education is not dated. In this article, I argue that ancient Egyptian philosophy of education must be reclaimed and centred on teacher education not only in South Africa but wherever Africans are. Such an approach will not only expose Africans to their rich philosophical heritage but will also help to reclaim African philosophy’s space as a leader of humankind in the history of philosophy.
Masculinity as a ‘hard small cage’? Reflections from Chimamanda Adichie’s We should all be feminists
Authors: Diabah Grace
Published: September 2022

With data from YouTube, this paper examines some masculinity issues raised by Chimamanda Ngozi Adichie in her TEDx talk ‘We should all be feminists’ and some selected interviews. She problematizes the masculine ideal of suppressing emotions and acting tough and uses them to gauge how masculinity can be described as a ‘cage’. To exemplify how this ‘cage’ might look like in reality, I draw on evidence from the literature on masculinity and men’s health as well as data from an unpublished document on discourses of fear and anxiety among male COVID-19 survivors in Ghana. Using the concept of hegemonic masculinity, I argue that the plethora of evidence in the literature suggest that (hegemonic) masculine norms indeed constrain men in ways that may have dire consequences, not only for their ego, but also for their health; hence, Chimamanda’s call to change the existing discourse is in order. Focusing on the ‘cage’ metaphor (including its qualifiers), however, I question Chimamanda’s description of masculinity since it suggests as though there is no room for contestation – something which weakens her own call for changing the narrative. The paper therefore proposes going beyond the kind of cage Chimamanda equates masculinity with, to make way for the needed interventions.

Published: September 2022

Heat treated steels that are quenched rapidly show an increase in hardness and toughness but also show an increase in brittleness which could lead to a higher surface roughness and low material removal rate while machining. Hence, the choice of quenchants has a significant effect on the hardness of low carbon steels. In this research work, the effect of some selected quenchants on the mechanical properties of heat treated and machined mild steel was investigated. Four samples of the carbon steel rods were furnace heated at 8500C and quenched with water, molten salt, potash alum and used engine oil. Central Composite Designs of Design Expert version 12 was used to plan the experiment. Machining factors used were, speed (100-450 rpm), feed rate (0.01-0.03 mm/rev), depth of cut (1-2mm). Surface roughness and material removal rate as well as the results of quenchant characterization were the responses studied. The favored quenchant was oil with the lowest surface roughness, hardness and material removal rate of 0.33μm and 187.78BHN and 0.020133mm3/min respectively. This is because the use of oil resulted in the highest reduction in surface roughness and enhanced material removal rate.

Published: September 2022

Purpose: This study was designed to investigate anticancer effect of ethanol and aqueous extracts of Lygodium microphyllum (Cav.) R.Br., Lygodium salicifolium Presl, and Licuala longecalyculata Furtado on human lung adenocarcinoma A549 cell line, and to determine total phenolic and flavonoid contents of those medicinal plants.

Methods: The three medicinal plants were extracted with ethanol and water using a rotary evaporator and freeze dryer, respectively. Cytotoxicity of the crude extracts at concentrations ranging from 3.125 to 200 μg/ml on A549 cells was determined using MTT assay at various times. Aluminium chloride colorimetric assay and the Folin-Ciocalteu colorimetric method were used to analyze total flavonoid and phenolic content, respectively.

Results: L. longecalyculata Furtado extracted with ethanol strongly inhibited A549 cell proliferation in a dose- and time-dependent manner with an IC50 value of 12.00±0.41 μg/ml, whereas L. microphyllum (Cav.) R.Br. and L. salicifolium Presl did not. In addition to the morphological changes, an anticancer effect was observed in L. longecalyculata Furtado-treated A549 cells. L. longecalyculata Furtado showed the presence of phenolic and flavonoid compounds.

Conclusion: These results indicate that in accordance with local wisdom, L. longecalyculata Furtado crude extract can empirically inhibit lung cancer cell line, but L. microphyllum (Cav.) R.Br. and L. salicifolium Presl cannot. However, further study of L. longecalyculata Furtado is needed to identify phytochemical compounds and their mechanism of anticancer action, in order to develop them as a new therapeutic agent for lung cancer management.

Published: September 2022

The article is devoted to the improvement of cross-cultural competence for future teachers. The study aims to develop directions and tools for the cross-cultural competence of teachers at different levels of organization and regulation of teaching education in the conditions of integrative processes.

The study's central hypothesis is that cross-cultural competence cannot be formed by implementing educational programs and requires an integrated approach at all levels of the pedagogical process. The relevance of the methods and tools for the cross-cultural competence formation of the future teacher in the conditions of integration processes is determined by three factors: transformation of the labor market, aggravation of intercultural perception problems in the world, insufficient amount of scientific research on this topic.

The research methods are used: analysis, synthesis, systematization, comparison, induction, and deduction. The study results allowed to form recommendations for the cross-cultural competence development of the future teacher at the individual, teaching, institutional and regulatory levels. The main content of the recommendations is the possibility of organizing practical communication experiences between students of different nationalities. The study's practical significance consists in the possibility of its use in the educational programs of pedagogical institutions of higher education.

The heating of an ethylene-propylene rubber (EPR) insulated cable installed in a vertical polyvinyl chloride (PVC) pipe is analysed in this paper. In particular, this paper considers the heating of an EPR cable used to energize a submersible water pump and analyses the upper part of the well where the space between the EPR cable and the inner surface of the PVC pipe is filled with air. The temperatures of the cable’s surface are determined analytically, and then such temperature values are validated numerically by using the finite element method (FEM) in COMSOL. In addition to these calculations, experiments are performed on a physical model representing the part of the well between the static water level and the solid concrete cover of the well. The percentage deviation of the calculated values for the cable’s surface temperature from the measured ones at different load currents ranges from 1.47% to 4.63%. After the experimental validation of the calculated values for the cable’s surface temperature, an analytic expression (i.e. correlation) that defines the dependence of that temperature on the load current and the pipe’s inner surface temperature is derived. Finally, an analytic expression for the cable load current as a function of the cable’s surface temperature and the pipe’s inner surface temperature is also derived, which can be further used to determine the ampacity of any power cable for known service conditions.

Published: September 2022

The aim of this study was to examine the influence of different small-sided games (SSGs) format on external, internal load and technical actions of professional U-23 portuguese soccer players. Eight players (20.1±0.8 years, 180.4±7.2 cm, 75.9±4.9 kg) performed three different 4 vs. 4 ball possession SSGs (3x3 min play/rest) in different pitch dimensions, SSG1 16x24 m, SSG2 20x30 m and SSG3 24x36 m. All SSGs were video recorded for technical actions analysis. WIMU PROTM (RealTrack Systems, Almeria, Spain) inertial devices were used for internal and external load data collection. The distribution normality was determined with the Shapiro-Wilk test. Parametric and nonparametric statistics were selected accordingly. Statistical Package for the Social Sciences (SPSS™ 25.0 version) was used for data analysis. No significant differences were observed comparing the different SSGs in total distance covered, acceleration/deceleration distance, as well as in maximal and mean heart rate. Regarding the technical actions, no significant differences were observed in successful passes, contrary to the observed from SSG1 to SSG3 in duels (7.00±2.13; 4.38±2.44; 4.25±1.98), number of balls lost (2.63±1.30; 1.00±0.53; 0.88±1.12) and in between SSGs in high-speed running (p<0.05, ES=0.37). In senior and professional soccer players, the modification of the pitch size between 16x24 m and 24x36 m during 4 vs. 4 ball possession SSGs with 3x3 min play/rest promotes modifications in the dynamic of technical actions and internal and external training load variables

Using a quasi-experimental methodology, a group of 8 subjects using the Gradior programme as cognitive stimulation therapy and a control group (8 subjects) with traditional cognitive stimulation without support software were analysed. The sample comes from an Elderly Care Home and a Diurnal Stay Unit, with subjects in the different stages of the disease, excluding those subjects with a level of impairment that could impede communication and execution of scales. A self-made sociodemographic questionnaire (reliability r= .863) and the Minimental State Examination (MMSE) scale, administered in two moments (pre-test and post-test) were used. Through a Spearman-type correlational analysis (statistical significance of p < .001), the non-parametric Mann-Whitney U test, and independent samples t-test (confirmation of alternative hypothesis H1, with a significance value of p= .001 in both measures), it can be affirmed that there is a relationship between the improvement of cognitive impairment and the use of the Gradior software. These conclusions are an enriching element for the different professionals who have intervened through cognitive stimulation with those subjects with Alzheimer's disease.

The biological factors of the human being are subject to both endogenous and exogenous circadian rhythms. The effects of the latter on cognitive, psychomotor and academic performance is burdensome. During the weekdays, the adolescent interactions are regulated by the school rhythm on the one hand and the biological fluctuations on the other. However, no studies till nowdays have investigated the relationship of academic performance with age and chronotype or analyzed  students’ time preferences of courses reviewing and familial socioeconomic status in a young Moroccan population. For this reason, we aimed to examine the impact of these variables on the scholar outcomes of Moroccan adolescents whose average age is 13 years, based on their grade levels.We used the “Morningness-Eveningness questionnaire (MEQ)” through its 19 multiple-choice questions to measure chronotype, while courses reviewing preferences on school days and familial socioeconomic status were investigated using a directive interview. As for the academic performance measures, we used the grade point average (GPA), extracted from “MASSAR platform” for each school subject.The majority of the sample is intermediate type (51.91 ± 9.66), 23.5% of it is morning type while the rest is evening type. Morning type students at all grade levels had a higher grade point average compared to moderate evening type. The results showed that chronotype has a main effect on both Humanistic/linguistic (p < .024) and Physical education grades (p < .031). While age (p< .001), mothers’ educational level and fathers financial status all have a significatif effect on students’ academic performance. Our results opt for the consideration of students’circadian typology, grade levels, time preferences and familial socioeconomic status when planning the school calendar, aiming from administrators to make small changes in the scheduling patterns that may improve the academic performance at a law-cost.

El conocimiento objetivo de los indicadores de juego que ocurren durante la competición permite a los entrenadores realizar planes de entrenamiento ajustados a las necesidades competitivas. El propósito de este trabajo fue analizar la influencia de la localización, el efecto de marcar primero y la calidad del oponente parcial y final en el resultado, en función del momento de la temporada en una liga profesional de fútbol. Para ello, se analizaron 114 jornadas de liga de la Primera División Española de Fútbol Masculino, correspondiente a tres temporadas (2014-2015, 2015-2016 y 2016-2017), con un total de 1140 partidos. Los resultados obtenidos, ponen de manifiesto la ventaja de los equipos que marcan el primer gol, ya sean locales o visitantes, consiguen un mayor número de victorias. En la primera vuelta se identificaron diferencias en todos los indicadores de juego (localización del partido, marcar primero, calidad de la oposición final), excepto en la calidad de la oposición parcial, mientras que en la segunda vuelta se encontraron diferencias significativas en todos los indicadores de juego. A partir de estos datos, los entrenadores deben realizar los cambios o estrategias necesarias para sacar el máximo rendimiento de su equipo y por consiguiente el resultado más positivo.
Abstract. The objective knowledge of the game indicators that occur during the competition allows coaches to make training plans adjusted to competitive needs. The purpose of this study was to analyse the influence of venue, the effect of being the first to score and the partial and final quality of the opponent in the result, according to the moment in the season in a professional football league.

El objetivo del presente estudio fue identificar los factores más determinantes en el fútbol profesional que hacen posible una mejora en el rendimiento del equipo al finalizar la temporada. Se realizaron entrevistas semi-estructuradas a 28 jugadores/as profesionales de fútbol (15 hombres y 13 mujeres), con edades comprendidas entre 27-41 años (M = 33.07, DT = 3.32). Todos ellos tenían experiencia profesional en la primera y segunda división española. El análisis temático de los datos se completó de manera deductiva e inductiva. Los resultados mostraron la complejidad existente dentro de un club de fútbol, con una notable importancia sobre la cohesión de equipo y sobre la figura del entrenador y cuerpo técnico para la mejora colectiva en ambos géneros. En cuanto al género, las jugadoras le dieron más importancia al staff técnico y los jugadores al tener en el equipo a deportistas con una buena calidad técnico-táctica. La relevancia de estos hallazgos radica en el conocimiento de los factores e interacciones potenciadoras y limitantes del rendimiento percibido por los jugadores/as en el fútbol profesional, así como las diferencias entre géneros. Este conocimiento podría ayudar a mejorar la gestión de grupos deportivos para potenciar el rendimiento de los equipos.
Abstract. The aim of this study was identify the most determining factors in professional football that make possible an improvement in team performance at the end of the season. Structured interviews were conducted with 28 professional soccer players (15 men and 13 women), aged 27-41 years (M = 33.07, SD = 3.32). All of them had professional experience in the first and second Spanish leagues. The thematic analysis of the data was completed deductively and inductively. The results showed the existing complexity within a soccer club, with notable importance on team cohesion and the figure of the coach and coaching staff for collective improvement in both genders. Regarding gender, female players provided more importance to the technical staff, whereas male players increased their value for having technical and tactical skilled teammates within the squad. The relevance of these findings lies in the knowledge of factors and interactions that enhance and limit performance perceived by players in professional football and the differences between genders. This knowledge could help improve the management of a sports group and the training planning, to enhance the teams' performance.
