Las Instituciones de Educación Superior están inmersas en procesos periódicos de evaluación y acreditación, que exigen el cumplimiento de estándares mínimos, siendo uno de ellos la Eficiencia Académica, compuesta por el indicador Retención Estudiantil, que se determina por la cantidad de estudiantes matriculados por primera vez al primer año manteniéndose en sus estudios dos años después. El presente estudio se desarrolla en la Universidad Agraria del Ecuador y tiene como objetivo determinar los factores de mayor incidencia en la deserción estudiantil, y se utilizó la Minería de Datos, con las técnicas de árboles de decisión y clustering para obtener los patrones de comportamiento que conllevan a la deserción, generando un modelo que permita predecir las deserciones. Se trabajó con los estudiantes de primer año de las diferentes carreras de las sedes de Guayaquil y Milagro, de los períodos lectivos 2014, 2015 y 2016, aplicando la metodología para descubrimiento de conocimiento (KKD,Knowledge Discovery in Database) donde se integran los datos iniciales, se seleccionan y se transforman los datos para la aplicación de la técnica escogida y posteriormente se evalúan y se difunden para permitir a las autoridades correspondientes la toma de decisiones, que conlleven a generar planes de acción que incrementen la tasa de retención de los estudiantes en la institución. Con la aplicación de las técnicas citadas se obtuvo que el factor más relevante que afecta a la tasa de retención en la institución, son los bajos promedios obtenidos durante los primeros semestres, así como la cantidad de asignaturas aprobadas, que conllevan a la pérdida de año de los niveles objeto de estudio.

Published: December 2024

Las comunidades de microalgas epibentónicas son organismos que generalmente se encuentran adheridos al sustrato marino, y en ocasiones encima de macroalgas. Gran parte de estos dinoflagelados son productores de toxinas causando síndromes de intoxicación en regiones tropicales y subtropicales. En ocasiones, cambios en los factores ambientales pueden desencadenar grandes proliferaciones denominadas “blooms”. Por tal motivo, el objetivo de este estudio es caracterizar la comunidad de microalgas epibentónicas potencialmente tóxicas a lo largo de la costa norte del Ecuador en la Reserva Marina de Galera San Francisco (RMGSF), y en su Archipiélago en la Reserva Marina de Galápagos (RMG) sobre diferentes especies de macrófitos. En la RMGSF, en Estero de Plátano, perteneciente a la provincia de Esmeraldas, se muestreó de noviembre 2016 a mayo 2017 los géneros de macroalga Padina y Coralina, recolectando un total de 36 muestras. En la RMG, las microalgas fueron recolectadas en tres sitios Bahía Tortuga, Santa Fé y Venecia, durante el mes de abril 2017 a través de 17 muestras de macroalgas verdes, pardas y rojas. En ambos lugares se determinó la presencia del género Ostreopsis sp, encontrando una mayor diversidad y abundancia de especies en Galápagos. En la RMG se identificó también Gambierdiscus sp en una de las muestras estudiadas, además de géneros como Prorocentrum, Amphidinium y Coolia. La presencia de estas microalgas potencialmente tóxicas a lo largo de la región litoral e insular del Ecuador podría asociarse a las condiciones ambientales favorables y a las características climatológicas de las áreas de estudio convirtiéndolas en ecosistemas propicios para el desarrollo y proliferación de estos microorganismos.

El desarrollo psicomotriz influye de forma relevante en el fortalecimiento de las habilidades básicas de aprendizaje como: lectura, escritura, ejecución de actividades artísticas y deportivas. En Ecuador, específicamente en la provincia Manabí, son escasas las investigaciones en este ámbito, lo que dificulta las posibilidades de su intervención exitosa. En este estudio descriptivo cuyo objetivo es determinar el índice y tipología de las alteraciones psicomotrices en niños y niñas el nivel básico elemental en tres escuelas fiscales de Jaramijó, se investigaron 569 niños y niñas en edades entre 5 y 8 años (media=6.5; dst=1.15). Se utilizó la Batería Psicomotriz de Víctor Da Fonseca, para medir el desempeño psicomotriz. En el análisis de los datos se utilizó la herramienta estadística SPSS versión 23.0; se detectó una alta incidencia de afecciones en la praxia fina, praxia global, estructuración espacio temporal, equilibrio, tonicidad  y noción del cuerpo . Menor alteración se manifestó en la lateralidad. No existe alguna diferencia significativa entre niños y niñas en cuanto a la tipología o índice de alteraciones psicomotrices (t=.810; df=567; p=.418). Se concluye que existe un retraso importante en el desarrollo psicomotor en la población estudiada. Se requiere atención personalizada para estimular aquellas destrezas y prevenir patologías en edades más avanzadas. El déficit en servicios de salud preventiva, y el nivel deficitario de instrucción de los padres incide negativamente en los procesos de desarrollo integral en estas edades críticas.
Evaluación de Impacto del Emprendimiento Innovador en el Desarrollo Económico: Situación de Santo Domingo de los Tsáchilas
Authors: Zapata Barros Ángel E. , Ugando-Peñate Mikel
Published: December 2024

Los recursos económicos disponibles para la producción son escasos; sin embargo, estos mismos recursos tienen usos alternativos en la medida que las ideas humanas son infinitas. En esta premisa descansa el concepto de innovación, por lo tanto, será un emprendedor innovador aquel que no solo busque la combinación eficiente de factores productivos, sino que también tenga como objetivo producir organizando los recursos económicos de formas diferentes. Desde una perspectiva macroeconómica, la economía ecuatoriana es primario exportadora, es decir sus ingresos dependen de actividades productivas con muy poco valor agregado, mientras que desde una perspectiva microeconómica su actividad productiva es escasamente innovadora; por lo tanto, los emprendimientos y las empresas hacen lo mismo (actividades primarias) de la misma manera (sin valor agregado).  Evaluar qué tan innovadora es una economía implica estimar qué tan innovadora es su población (iniciativa creativa individual) para, a partir de este análisis particular, sacar conclusiones de carácter colectivo (provincia, ciudad, región) y de esta manera valorar las posibilidades de alcanzar el desarrollo económico, así como estimar la sostenibilidad de las actividades productivas (empresas). Con el propósito de evaluar el impacto de la innovación, se desarrolló este estudio en tres etapas (planificación, ejecución y presentación de resultados), que son una adaptación de los ocho pasos sugeridos por la metodología de evaluación de impacto de la Unión Europea 2006.

The practical application of AI in large organizations such as SAP, Siemens AG, Rimac Automobili, and Infobip provides concrete examples of its potential to enhance project efficiency. These case studies illustrate how AI can provide a competitive advantage to managers and their organizations in the contemporary business environment. The deployment of AI in project management is transformative, offering substantial improvements in efficiency, adaptability, and strategic planning. The evidence from case studies underscores the value of AI in achieving superior project outcomes and maintaining a competitive edge in today's dynamic business context.
ravni okvir zelene javne nabave kao čimbenika održivog razvoja
Authors: Gregurić-Bajza Ninoslav
Published: December 2024

U zadnjih nekoliko desetljeća ljudi su nekontroliranom i nerazumnom eksploatacijom prirodnih resursa, enormnim korištenjem fosilnih goriva i nizom sličnih postupaka utjecali na oslobađanje ogromne količine stakleničkih plinova i globalno zagrijavanje planeta Zemlje, što je negativno utjecalo na životni okoliš i biosferu. Stoga se ljude sve više poziva na razumno ponašanje, a države na ulaganja u obnovljive izvore energije, na donošenje mjera za smanjenje stakleničkih plinova i općenito na održivi razvoj. Kako više od 250.000 javnih tijela u EU kroz javnu nabavu svake godine potroše oko 16% BDP-a (oko dvije milijarde eura) na nabavu usluga, radova i robe, neprijeporno je da zelena javna nabava može biti jedan od vrijednih i učinkovitih alata za politiku održive proizvodnje i potrošnje. Zakon o javnoj nabavi usklađen je s pravnom stečevinom EU, a kao takav sadrži i pravni okvir koji daje mogućnost ali ne i obvezu, za provođenje zelene i društveno odgovorne javne nabave. S tim u vezi, ovim se radom nastoji ukazati kako bi uz drukčije uređeni strateški i pravni okvir, zelena javna nabava zaista mogla biti važan i učinkovit čimbenik zaštite okoliša i održivog razvoja. Stoga se u radu deskriptivnom i komparativnom metodom navodi i opisuje europski i nacionalni strateški i pravni okvir zelene javne nabave, te se ukazuje kako bi se uz adekvatnu izmjenu toga okvira, pravne norme zelene javne nabave osnažile i kao kogentne, a ne više kao dispozitivne pravne norme, u značajnijoj mjeri doprinijele zaštiti okoliša i održivom razvoju.

Authors: Lulić Iva , Kadlec Željka
Published: December 2024

Ovaj rad istražuje primjenu održivog razvoja u poslovanju na primjeru poduzeća "dm drogerie markt", koje je poznato po svojoj predanosti ekološkim i društvenim inicijativama. Svrha rada je prikazati kako održivi razvoj može biti integriran u poslovne strategije te kako doprinosi financijskom uspjehu i društvenoj odgovornosti poduzeća. Metodologija istraživanja uključuje kombinaciju kvalitativnih i kvantitativnih analiza pri čemu kombinira pristupe specifične za interdisciplinarno istraživanje temeljeno na socio-ekološkom i etičkom pogledu ugrađenom u ekonomsku analizu. Kvalitativna komponenta se temelji na uvidima koji su oblikovani na temelju proučavanja literature, pri čemu veliku ulogu imaju tumačenja iz područja socijalne ekologije Ivana Cifrića, dok kvantitativna komponenta uključuje analizu godišnjih izvješća i statističkih podataka o poslovanju poduzeća. Pored toga, literarna analiza pruža širi kontekst o održivom razvoju, ESG strategijama te njihovom utjecaju na poslovne performanse. Doprinos ovog rada očituje se u pružanju konkretnih primjera uspješne implementacije održivih praksi u poslovanje. "dm" se ističe kao organizacija koja koristi održive prakse za stvaranje konkurentske prednosti, istovremeno promovirajući ekološku svijest i odgovorno ponašanje među zaposlenicima i potrošačima. Rad također nudi smjernice za druga poduzeća koja žele integrirati održive prakse u svoje poslovne modele te otvara prostor za daljnja istraživanja utjecaja održivosti na dugoročne poslovne rezultate.
Stavovi javnosti u ruralnim područjima o razumijevanju i važnosti koncepta pravedne trgovine
Authors: Pavić Andrea , Jaković Božidar , Tubić Dejan
Published: December 2024

Pravedna trgovina kao koncept ima za cilj poboljšati životne uvjete proizvođača iz zemalja trećeg svijeta, potaknuti njihov razvoj i napredak te promicati pravedniji i održiviji globalni trgovinski sustav podizanjem svijesti potrošača i promjenom pravila i prakse međunarodnih trgovina. Glavni cilj ovog rada je analizirati nedovoljno istražen i jasno definiran koncept i načela pravedne trgovine, te ispitati stavove javnosti u ruralnim područjima o razumijevanju i važnosti ovog koncepta. Primarni podaci prikupljeni su strukturiranim upitnikom na hrvatskom jeziku, korištenjem nominalne, intervalne i omjerne mjerne ljestvice. Anketnom metodom ispitano je 60 ispitanika o poznavanju pojma i percepciji njegove važnosti, a podaci su obrađeni deskriptivnom statističkom analizom. Analiza i interpretacija dobivenih podataka pomogla je u donošenju konačnih razmatranja o samom konceptu i implikacijama za buduća istraživanja. Istraživanje i analizirani podaci daju dublji uvid u percepciju i stavove potrošača o pravednoj trgovini i njenim proizvodima. Evidentno je da usprkos rastućem interesu za etičke i ekološke aspekte proizvoda, kod potrošača u ruralnim područjima ne postoji dovoljna svijest o konceptu pravedne trgovine. Ovaj nedostatak svijesti može proizaći iz nedostatka informacija i obrazovanja o tome što pojam pravedne trgovine znači i kako konzumacija ovih proizvoda može doprinijeti društvenoj pravdi i održivosti. Najznačajnije prepreke su nedostupnost ovih proizvoda u trgovinama te cijene proizvoda sa oznakom pravedne trgovine koje su još uvijek visoke.

Published: December 2024

Svrha ovoga rada je prezentirati ideju pametnog grada, ali propitati njihovu ulogu u stvaranju održivog društva. Kako bi se to postiglo, rad u svome prvom dijelu deskriptivnom metodom opisuje teorijsku podlogu nastanka ideje održive zajednice odnosno pametnog grada. Uz to prvi dio rada koristi se i historijskom metodom kako bi opisao povijest razvoja pametnih gradova i najistaknutijih primjera, a time bi se stvorio dostatan okvir za daljnju analizu. Drugi dio rada analizira primjere dobre prakse na području EU, uz stavljanje naglaska na analizu primjera Grada Zagreba. Takva analiza za cilj ima istražiti kako ovakvi gradovi poboljšavaju svoje usluge, racionaliziraju potrošnju, ali i kako postaju temelj za ekonomski progres svojih stanovnika. Kako bi se postigla što veća relevantnost rezultata, rad se služi i komparacijskom metodom, utvrđujući sličnosti i razlike između rješenja u Zagrebu i drugim odabranim primjerima. Glavni rezultati ovoga rada mogu se također podijeliti u dvije glavne skupine. Prva skupina rezultata je na teorijskoj razini, te će ona doprinjeti promišljanjima, do sada još uvijek nedovoljno istraženoj temi iz perspektive toerijskog diskursa, povećavajući opseg znanja, ali I literature o ovoj tematici. Druga skupina rezultata pak je praktične naravi, te će ona doprinjeti boljem sagledavanju prednosti i nedostataka pametnih gradova, s ciljem daljnjeg poboljšanja samih rješenja koje ovi gradovi već imaju, ali i uspostave nekih novih ideja proizašlih Iz komparativne analize. Na kraju, rad svakako ima i dimenziju društvenog doprinosa, jer skreće pažnju na danas vrlo aktualna pitanja održivosti i zelene ekonomije.

Authors:   Faculty of Veterinary Medicine, University of Calgary, 3280 Hospital Drive NW, T2N 4Z6, Calgary, Alberta, Canada, Farghal Mostafa ,   Faculty of Veterinary Medicine, Minia University, Minia, Egypt
Published: December 2024

Nanotechnology has emerged as a transformative approach in medicine, with extensive applications in diagnostics and therapeutics. In diagnostic imaging, it has significantly enhanced accuracy, sensitivity, and specificity in disease detection, surpassing traditional imaging modalities. Nanoparticles, such as magnetic and gold nanoparticles, have contributed to improved resolution and contrast, enabling earlier and more precise diagnoses such as the use of superparamagnetic iron nanoparticles in detecting early-stage tumors. Despite its promise, the clinical application of nanotechnology faces significant challenges, including high costs, lack of standardized regulatory frameworks for its use (such as guidelines for follow-up evaluation), and concerns about the long-term safety of nanoparticles. For example, the accumulation of nanoparticles in the body affects the immune, respiratory, and cardiovascular systems. Addressing these issues requires further research to ensure its safe and effective integration into clinical settings. Although the existing literature provides valuable insights into nanotechnology applications, it often tends to be either too specialized or overly general, creating a gap in the comprehensive knowledge regarding its role in diagnostic imaging. This review aims to provide a comprehensive overview of the role of nanotechnology in diagnostic imaging, focusing on its applications in enhancing techniques such as magnetic resonance imaging, computed tomography, and ultrasound. It also explores current challenges and future directions, emphasizing the need for continued research to fully realize the potential of nanotechnology in clinical practice. Future research should focus on the development of nanoparticles with no adverse health effects, the creation of techniques to assess the long-term health impacts of existing nanoparticles, and the establishment of international standards for their clinical use.
Mitandao ya Kijamii, Mkenya “Mwasi” katika X, hapo awali Twitter, na Mijadala ya Uana, Jinsia na Ngono
Authors: Mwathi Virginia , Ndivo Larry
Published: December 2024

Mitandao ya kijamii imekuwa ikitumika sana kama vyombo vya mawasiliano na utangamano miongoni mwa watu katika ulimwengu wa sasa. Kando na kutupa uhuru wa kusambaza maoni yetu, mitandao ya kijamii imewezesha watu wengi kutoa maoni yao kuhusu masuala ya kiuchumi, kijamii na kisiasa hata kuliko zamani. Habari nyingi zinazosambazwa katika mitandao hii hazidhibitiwi kwa vile zinatokana na fikra za kibinafsi, mihemko na makabiliano ama majibu ya papo hapo ambayo inaweza kuwa yenye mapendeleo. Kutokana na haya, makala hii ilichanganua jumbe teule za mwanamtandao Mkenya maarufu aitwaye Eric almaarufu Amerix katika mtandao wa X, (hapo awali Twitter), akijitambulisha kama @Amerix. Ilitathmini kauli zake kwa kuhusisha nadharia za ubabedume na ufeministi. Kwa maoni yetu, tunadai kuwa @Amerix amechukua nafasi hii ya kuwepo kwa pengo la kijinsia linalodumu kushughulikia masuala ya ‘wanaume’ lakini kwa upande mwingine, tungependa kuonyesha kuwa inawezekana kuwa shughuli zake zimedhoofisha maendeleo ambayo yalikuwa yashapatikana katika kuumbua mifumo ya kiubabedume katika mpito wa wakati. Data ilikusanywa kwa usampuli wa kimakusudi ambapo jumbe teule zilizopata majibu mengi, zikasambaa sana na hata kupendwa zilitumika. Jumbe zilizoteuliwa ni zile zenye kuibua umaarufu kutokana na nembo ya hashtag #MasculinitySaturday inayotokana na vipindi vya @Amerix vya Jumamosi na kusababisha wafuasi wake wengine kumtuhumu kama anayeendeleza itikadi za kiubabedume. Utafiti huu ulibaini kuwa @Amerix ni mwenye taasubi ya kiume kutokana na anavyotetea masuala ya kiume. Aidha, ilidhihirika kuwa ni ‘mwasi’ kwa vile anapinga baadhi ya tamaduni ambazo zimekuwepo na hata maendeleo ambayo yalikuwa yashapatikana katika kuleta usawa wa kijinsia. Tunapendekeza watafiti wa baadaye kuchunguza namna majukwaa mengine yanavyoshughulikia suala la kijinsia. Pia, wanaweza kutoa suluhu la udunishaji wa jinsia moja. Tunatumai kuonyesha kuwa mitandao ya kijamii inatoa kipera ibuka cha mahusiano ya kifasihi na kutokana na hayo, kukutana kwa ubunifu na mijadala ya kifasihi.
Dancing necessities
Authors: Ullerup Schmidt Cecilie , Bork-Petersen Franziska , Schnor Jonas , Vedel Karen
Published: December 2024

Summary
Situating the vocabulary of infrastructure studies within the field of dance, theatre- and performance studies, the article provides a critical analysis of what has happened infrastructurally within the past 10 years in the Danish field of dance and choreography. Four aspects are taken into account: the landscape and economy of venues, the educational changes, an upsurge of self-organised spaces and cooperatives in the field, and finally the field of critique and self-archiving. Through an analysis across frames of production, presentation, and distribution, we suggest tendencies of how dance and choreography is currently moved by its material and immaterial infrastructures. The conclusion stresses how artistic self-organisation of both production platforms, festivals, and separatist collectives can be understood as infrastructural choreographies: artistic and self-maintaining ways of responding to institutional and educational instability, structural precarity, and normative representation in the Danish landscape of dance and choreography.
 
Resumé
Ved brug af et vokabular fra infrastrukturstudier i konteksten af dansevidenskab og teater- og performancestudier giver artiklen en kritisk analyse af, hvad der er sket infrastrukturelt i de seneste 10 år i det danske danse- og koreografifelt. Fire aspekter tages i betragtning: et landskab over scener og tilhørende økonomi, forandringer i de nationale uddannelser indenfor dans og koreografi, en fremkomst af selvorganiserede studios og kooperativer, og endelig betingelserne for kritik og arkivering af dans. Ved at analysere på tværs af rammer for produktion, præsentation og distribution, beskriver vi hvordan dans og koreografi i vores historiske samtid formes af feltets materielle og immaterielle infrastrukturer. Konklusionen foreslår, at kunstnerisk selvorganisering af både produktionsplatforme, festivaler og separatistiske kollektiver kan forstås som infrastrukturelle koreografier: kunstneriske og omsorgsdragende måder at reagere på institutionel og uddannelsesmæssig ustabilitet, strukturel prekaritet og normativ repræsentation i det danske felt for dans og koreografi.

RPM w handlu elektronicznym – la nouvelle vague czy nihil novi? Przegląd praktyki decyzyjnej organów ochrony konkurencji
Authors:   Wydział Prawa i Administracji Uniwersytetu Łódzkiego, Laszczyk Anna
Published: December 2024

Celem artykułu jest dokonanie analizy wybranych decyzji KE i wybranych krajowych organów ochrony konkurencji dotyczących porozumień wertykalnych polegających na ustalaniu cen odsprzedaży w handlu elektronicznym. Przyczynkiem do podjęcia tej tematyki jest niedawne badanie sektorowe KE analizujące konkurencyjność handlu elektronicznego. Wnioski z tego badania wskazują, że dostawcy w znaczny sposób wpływają na politykę cenową swoich odsprzedawców, co potencjalnie – w ocenie organu – może mieć negatywny wpływ na konkurencję. W artykule w pierwszej kolejności przedstawiona jest charakterystyka handlu elektronicznego i ewentualnych, istotnych z perspektywy prawa konkurencji, różnic w stosunku do handlu tradycyjnego. Charakterystyka ta pozwala postawić hipotezę o braku podstaw do tworzenia nowych kryteriów analizy RPM w kanałach dystrybucji online. Hipotezę tę zdaje się również potwierdzać analiza praktyki decyzyjnej organów ochrony konkurencji. Jednocześnie okoliczność stosowania RPM w handlu elektronicznym powinna skłaniać organy ochrony konkurencji do uważnej analizy kontekstu ekonomicznego tej praktyki, w tym w szczególności potencjalnej motywacji dostawcy do jej wdrożenia.
Huellas del Bellum Sertorianum en las ciudades de la Hispania Citerior
Authors: Gómez Marín Javier
Published: December 2024

El bellum sertorianum representa una continuación y conclusión del enfrentamiento civil que desde el 88 a.C. sacudía Roma. Las luchas entre populares y optimates se saldaron en el 81 a.C. con la victoria optimate y la proclamación de Lucio Cornelio Sila como dictador perpetuo. Ante tal situación, Quinto Sertorio, enemigo declarado de Sila, convirtió la península ibérica en su fuente de suministros y base de operaciones desde la que continuar su lucha contra el régimen silano, iniciando así un nuevo conflicto que durante diez años convirtió gran parte de la Península en un sangriento campo de batalla. Esta publicación recopila parte de las evidencias que se han localizado en los asentamientos urbanos partícipes en el conflicto, mostrando con dramática claridad las consecuencias y repercusiones fruto de estas guerras. De igual modo, observaremos las dificultades existentes entre la asociación de estos vestigios con el conflicto sertoriano y su datación cronológica.

Enzymatic protein fusions with 100% product yield
Authors: Fuchs Adrian CD
Published: December 2024

The protein ligase Connectase can be used to fuse proteins to small molecules, solid carriers, or other proteins. Compared to other protein ligases, it offers greater substrate specificity, higher catalytic efficiency, and catalyzes no side reactions. However, its reaction is reversible, resulting in only 50% fusion product from two equally abundant educts. Here, we present a simple method to reliably obtain 100% fusion product in 1:1 conjugation reactions. This method is efficient for protein-protein or protein-peptide fusions at the N-or C-termini. It enables the generation of defined and completely labeled antibody conjugates with one fusion partner on each chain. The reaction requires short incubation times with small amounts of enzyme and is effective even at low substrate concentrations and at low temperatures. With these characteristics, it presents a valuable new tool for bioengineering.

Published: December 2024

This paper explores the use of unplugged activities as a pedagogical approach for teaching computational thinking (CT) to student teachers at a Danish university college in the subject technology comprehension. Through an analysis of three cases—a toothbrushing routine, a political profiling quiz, and an interactive story creation—the study examines students’ learning experiences and engagement with CT concepts and practices. The paper employs a methodological approach rooted in participatory observation and visual ethnography. Data collection includes video recordings, audio recordings, post-class interviews, and artefacts created by the students.
The analysis reveals possibilities as well as challenges experienced by students in their involvement in computational thinking activities, including algorithms, decomposition, and abstraction. These findings contest the oversimplified classification of activities as either 'plugged' or 'unplugged', suggesting that alternative factors hold more substantial importance. Subsequently, the paper explores the roles of self-efficacy and ‘be-greifbarkeit’ in students' learning processes, thereby elucidating how students' motivation and learning expectations, in conjunction with their tangible experiences and conceptual understandings, influence the development of their computational thinking competencies.
In conclusion, the study provides valuable insights for teacher educators, emphasising the need to consider the perceived complexity of the activity, including the students’ prerequisites for engaging with plugged and unplugged elements. It highlights the multifaceted nature of plugged and unplugged approaches, offering a nuanced perspective on their impact on students' learning experiences in the field of computational thinking.
Numerical estimation of the subgrade reaction modulus of a horizontally loaded piled raft
Authors: Alva García Francisco Javier , Muniz de Farias Marcio , Medina Garcia Liosber
Published: December 2024

A horizontal full-scale test was executed in a piled raft with a single pile. Later, from those measured experimental results, some numerical simulations were carried out using a commercial software Abaqus 2019 obtaining acceptable approximations. During the numerical analysis, the elastic-plastic behavior of each material comprising the foundation system has been considered, including the soil, the concrete, and the steel. Based on such numerical approximations, a polynomial function that represent the pile deflections along the pile shaft has been calculated and plotted. Later, from this function the rotation, the bending moments, the shearing forces, and the load intensity along the pile were estimated; also, the subgrade reaction modulus of the soil was computed, and some p-y curves at specific depth points are presented according to the numerical results. Finally, this paper allowed obtaining a clear idea about the behavior and distribution of the internal forces not only in the foundation soil but also in the pile, from a success numerical performance.

Published: December 2024

Power generation through photovoltaic technology has become an essential source of electricity in the world in recent years. In Brazil, it is already the second most immense installed power in the electrical matrix, and, as a result, anomalies in photovoltaic panels tend to become a source of losses because they are elements exposed to the actions of nature. Techniques for detecting problems in panels have been studied, and among these, the use of thermographic images collected with the help of drones stands out. In this work, a solution is developed using computer vision and artificial intelligence techniques for detecting and classifying anomalies. It aims to assist operation and maintenance teams in deciding what type of intervention to carry out, thus optimizing their work and mitigating more significant losses. The average result of the Recall metric was over 95% accuracy, demonstrating the viability of its use for developing a solution for the photovoltaic system maintenance market.

Published: December 2024

This study was carried out to determine the impact of teaching-style safety training on safety performance in selected oil and gas companies in Niger Delta, Nigeria. Safety performance was operationalized using safety compliance, safety participation and accident occurrence. The study adopted inferential research design. Multi-stage sampling technique was used to sample few companies from the population while Taro Yamane sample size formula was used to estimate 400 as sample size. Structured questionnaire, designed based on five-point Likert scale, was used for data collection. Regression and structural equation model were used for the data analyses. The results of regression and structural equation analyses revealed that teaching-based safety training has positive and significant impact on safety compliance (β = 0.263 p-value = 0.000 < 0.05) but positive and insignificant impact on safety participation and accident occurrence (β = 0.054 p-value = 0.534 > 0.05, β = 0.074 p-value = 0.371> 0.05, respectively). The results also revealed that only safety compliance has complete mediating effect in relationship between teaching-based safety training and accident occurrence. It was concluded that teaching-based safety training has partial impact on leading safety performance (safety compliance) but no significant impact on lagging safety performance (accident occurrence) and recommended that management of oil and gas firms should utilize complete safety training package for their workers to ensure sustainable level of safety performance.

Authors: Tapic Jesana N. , Baguio Josephine B.
Published: December 2024

This study examined the restoration leadership practices and collegial model of public elementary school teachers in the Sta. Maria District, Division of Davao Occidental. Restoration leadership practices refer to strategies aimed at fostering accountability, empathy, and open communication to address and repair conflicts or challenges within the school community. The collegial model emphasizes collaboration and shared decision-making among teachers. Using a non-experimental quantitative research design and the correlational method, this study analyzed responses from 139 public elementary school teachers selected through universal sampling. Data were analyzed using mean scores, Pearson r, and regression analysis. The findings revealed that restoration leadership practices were moderately extensive, with a mean score of 3.46, while the collegial model was also moderately extensive, with a mean score of 3.09. Moreover, restoration leadership practices were found to be significantly related to the collegial model, with a p-value of 0.01. Based on these findings, it is proposed that a professional development program be implemented to encourage teachers to participate in DepEd conferences and training focused on enhancing restoration leadership practices and promoting collegiality. This program aims to address the need for stronger interpersonal relationships, improve instructional quality, and foster a sustainable, inclusive educational environment. Schools may also consider adopting targeted interventions to further strengthen leadership practices and promote a collegial culture, thereby supporting both teacher development and student success.

Published: December 2024

Humans have been using plants in traditional medicine and for food security for millions of years. Today, several plants are being studied for their nutritional and medicinal value. The aim of this study was to determine the macronutrient composition, the characteristics of the oil and the mineral and phytochemical amino acid profiles of the fruit kernels of Maranthes polyandra (Benth.) Prance collected in the Cascades region of Burkina Faso. Macronutrient composition, oil characteristics and phytochemical profile were determined using standard methods. Amino acid and mineral profiles were determined by liquid chromatography coupled to a tandem mass spectrometer (LC-MS/MS) and inductively coupled plasma atomic emission spectrometry (ICP-AES) respectively. The results of the analyses revealed average levels of protein (14.5 ± 0.2 g/100g), lipids (55.5 ± 0.5 g/100g) and carbohydrates (25.2 g/100g). The average saponification, iodine, acid and peroxide values of the oils were 190.92 mg KOH/g oil, 148.11 g iodine/100 g oil, 0.24 mg KOH/g oil and 25.33 mEq of O2/kg oil. Essential amino acids (Threonine, Histidine, Isoleucine and Leucine) and non-essential amino acids (Alanine, Glycine, Arginine and Glutamic acid) were reported at varying levels. Almonds also contained ten types of minerals (B, Ca, Fe, K, Mg, Na, P, Si, Sr and Zn), total fiber (11.10%), phytate (12.46 g/kg) and polyphenols (0.13%). Almonds contained simple sugars (mg/kg) such as D-mannopyranose (41.80), Ribose (149.27), L-Rhamnose monohydrate (70.86), Glucuronic acid (161.41), Trigalacturonic acid (19.44), α-D-glucose (608.82), α-D-galactose (253.05), Aldehydo- D-xylose (22.23), Aldehydo-L-arabinose (49.72), Fucopyranose (510.58). Fructose was not detected. This study revealed that the fruit kernels of M. polyandra are highly rich in nutrients and can be used in food fortification to combat malnutrition in Burkina Faso.
