Relationship between Sociocultural Characterization in Regular Basic Education Students from High Andean Zones and their Interaction in Educational Metaverses por Zúñiga Pastor, Francisco, Loayza-Apaza, Yesenia Tania, Velarde-Tejada, Milusca Jacqueline, Barrientos-Alfaro, Alvaro Rafael, Romero Carazas, Rafael, Bernedo Moreira, David Hugo

“…Introduction: The sociocultural characterization of students includes factors such as ethnicity, language, beliefs, social practices, family environment and other elements that affect their perception of knowledge and technology; for environments to be effective, it is essential to consider the sociocultural characterization of students, since the factors profoundly affect the ability to adapt to new teaching methods.Objective: To determine the relationship between sociocultural characterization in regular basic education students from high Andean areas and their interaction in educational metaverses.Methods: A quantitative and correlational approach was adopted with a non-experimental design, focusing on 376 university students who had taken at least one semester in virtual mode. …”

Adsorption of hydrogen sulfide by activated carbon produced by regeneration of sludge from upflow anaerobic sludge blanket por Torres Calderon, Soledad, Pampa Quispe, Noe Benjamin, Cruz Huaranga, Milda Amparo

“…The objective of this study was to determine the efficiency of H2S adsorption by activated carbon obtained from the regeneration of sludge from an Upflow Anaerobic Sludge Blanket (UASB).The H2S adsorption system was carried out in the Chemistry laboratory of the Universidad Peruana Unión, the inflow of the fixed bed towers was 4 L•min -1 and 36 g of adsorbent media (6 different Active Carbon (AC), depending on Pyrolization temperatures (PT) and [M] KOH), AC at PT 700 ºC/1M, AC PT 500 ºC/4M, AC PT 500 ºC/1M, AC PT 700 ºC/4Mand AC PT 600 ºC/2.5 M the last with two repetitions.The adsorption of H2S was determined by the volumetric oxidation-reduction method.The parameter of the greatest influence for the adsorption of H2S was PT at 99 and 90% CI respectively, demonstrated by 22 and 32 factorial designs; satisfactory elimination efficiencies of H2S were obtained and reached 94% during a retention time of 20 minutes of activated carbon at PT 700 ºC and [1M] KOH.For the response surface prediction simulation, the optimized parameters for the removal of H2S approximately greater than 96% was at PT of 635 ºC and activating agent of [2.6 M] KOH.Therefore, the adsorption of H2S by activated carbons for sludge is a new, viable and sustainable alternative for the environment.…”

Digital Competencies and Transformational Leadership as Predictors of Job Performance in University Teachers por Madrid, Carina, Chimborazo, J Luis, Morales Garcia, Wilter Charming, Quispe Sanca, David, Huancahuire Vega, Salomon, Sanchez Garces, Jorge Alejandro, Saintila, Jacksaint

“…COVID-19 has adversely impacted the entire university community worldwide, including teachers, administrative staff, and students.This study analyzed the relationship between digital competencies, transformational leadership, and job performance of Peruvian university teachers.A predictive crosssectional study was conducted with 201 teachers from a private university in Peru in three regions of the country (coast, highlands, and jungle).The Digital Competencies in Teaching (CDD), Multifactor Leadership Questionnaire (MLQ 5X Short), and the Job Performance scale were used for data collection.The samples were analyzed with structural equation modeling and an adequate fit to the data was obtained (χ 2 = 194.342,p < 0; χ 2 /df = 2.23, CFI = .952,TLI=0.942,RMSEA = .078,SRMR = .061).In addition, both digital competencies (β = .28,p < 0) and transformational leadership (β = .76,p < 0) were found to be predictive factors of job performance.These findings provide evidence that digital competencies and transformational leadership were directly related to the job performance of university teachers during the COVID-19 pandemic.Consequently, it would be appropriate for educational leaders to consider these findings to enhance the digital competencies of teachers, promote a positive work environment, and support professional growth by stimulating motivation and job satisfaction during crisis situations.…”
