The service-learning strategy "MicroMundo" helps to stimulate the practical training of future secondary education teachers
Get PDF[EN] The “MicroMundo” project is an innovative educational initiative designed to address the issue of antibiotic resistance through a collaborative and service-learning approach focused on detection of antibiotic-producing bacteria. Due to COVID-19 restrictions, MicroMundo was adapted by integrating university students enrolled in the “Master’s in Teacher Training for Secondary Education” (SWITAs) which mentored high school students (SWISs) through the laboratory research experience. Evaluation of the project through surveys highlighted strong satisfaction among participants, with 100% of university students valuing the teaching experience and 80% reporting gains in essential skills such as planning and communication. Pre-university students also highly valued this experience, reporting an increase in motivation despite the challenging circumstances, and noting that it sparked their interest in the field of science. This hands-on approach reinforces the need for practical, research-based experiences and emphasizes the importance of raising awareness about critical health challenges, particularly in contexts beyond the scientific field.SIThis project was supported by the teaching innovation program founded by the University of León

Artificial insemination of all ejaculated sperm fractions accelerates embryo development and increases the uterine vascularity in the pig
Get PDF[EN] The semen of boar is characterized by ejaculation in well-differentiated fractions with specific concentration, composition, and volume. The ‘sperm-rich fraction' (SRF), the most concentrated seminal fraction, is habitually collected in insemination centers to make artificial insemination (AI) doses. The absence of the other fractions in AI doses could alter the uterine reaction to AI and not trigger essential responses that could maximize fertility. Thus, there is an urge to ascertain the impact of different ejaculate fractions on the uterus after AI to optimize the semen doses. This work analyzed specific parameters related to fertility in pregnant artificially inseminated sows (n = 15) with ac-cumulative fractions of the semen of boars (n = 6): F1, composed of the sperm-rich fraction (SRF); F2, composed of F1 plus the intermediate fraction; F3, composed of F2 plus the post-SRF. Non-inseminated sows (n = 5) were included as control (C). The different types of seminal dose did not affect the number of ovulated follicles (CL; corpora lutea, p > 0.05) but did affect the embryo development (p 0.05). Independently of the type of seminal dose (F1, F2, or F3), we observed by immunohistochemistry that AI significantly increased uterine vascularization, although with some anatomical differences. The cranial region of the uterine horns was significantly more vascularized in AI-F1 or AI-F2 sows (26.7 ± 2.3 and 28.6 ± 2.0%, respectively), and AI-F3 showed significantly less vascularization at that point (17.8 ± 1.6%, p < 0.05). To summarize, the synergistic effect of all ejaculate fractions accelerates embryo development, at least during the preimplantation period, and increases the uterine reaction to AI in certain parts of the uterusSIThis research was supported by the Séneca Foundation (21656/21), Ministry of Science 381 and Innovation (PID2019-106380RBI00/AEI/10.13039/501100011033) and European Union 382 “Next Generation” EU/PRTR (PDC2022-133589-I00
Home Electricity Sourcing: An Automated System to Optimize Prices for Dynamic Electricity Tariffs
Get PDF[EN] Governments are focusing on citizen participation in the energy transition, e.g., with dynamic electricity tariffs, which pass part of the wholesale price volatility to end users. While often the cheapest alternative, these tariffs require micromanagement for optimization. In this research, an automated system capable of supplying electricity for home use at minimal cost called Smart Relays and Controller (SRC) is presented. SRC scrapes prices online, charges a battery system during the cheapest time slots and supplies electricity to the home energy system from the cheapest source, either the battery or the grid, while optimizing battery life. To validate the system, a comparison is made between SRC, a programmable scheduler and PVPC (Spain’s dynamic tariff) using twenty-eight months of hourly historical data. SRC is shown to be superior to both the scheduler and PVPC, with the scheduler performing worse than SRC but better than PVPC (T.T., p < 0.001). SRC achieves a 36.16% discount over PVPC, 13.89% when factoring in battery life. The savings are 44.24% higher with SRC than with a scheduler. Neither inflation nor incentives to reduce costs are considered. While we studied Spain’s tariff, SRC would work in any country offering dynamic electricity tariffs, with benefit margins dependent on their particularities. Keywords: electricity consumption optimization; electric smart control; dynamic electricity tariffs; PVPC; SRCSIThis initiative was executed within the framework of the Recovery, Transformation and Resilience Plan funds financed by the European Union (Next Generation)

Reproductive performance and backflow study in cervical and post-cervical artificial insemination in sows
Get PDF[EN] The present study was developed to evaluate multiparous sow reproductive performance and backflow in post-cervical artificial insemination (post-CAI) using a reduced number of sperm than in cervical artificial insemination (CAI). The experimental groups were divided into sows inseminated by: 1) cervical artificial insemination (CAI): 3×109 spermatozoa/80ml; 2) post-CAI: 1.5×109 spermatozoa/40ml (post-CAI 1); 3) post-CAI using 1×109 spermatozoa/26ml (post-CAI 2). Post-CAI 1 reproductive parameters were similar to those of post-CAI 2 (except for live born litter size which was greater in post-CAI 1) and better than for the CAI group (p<0.01). In a second experiment the backflow volume, number of sperm, and sperm quality in the backflow were studied in the 3 experimental groups. The % of volume and spermatozoa in the backflow was higher in the CAI group (p<0.05) than post-CAI groups (statistically similar between them). Moreover, the quality parameters (motility, progressive motility, viability, chromatin decondensation and morphology) in backflow semen were identical in all three experimental groups, but differed as regards the original insemination dose incubated inside a colostomy bag (sperm quality control group). The present study shows that the use of post-CAI (either post-CAI 1 or 2) in field conditions can be recommended because the efficiency is similar (in the case of post-CAI 2) or higher (post-CAI 1) than when using the traditional method (CAI), representing a reduction costSIThis research was supported by grant Fundación Séneca (08752/PI/08) and by AGL2009-12512-C02-01 from the Spanish Ministry of Science and Innovation and FEDER.

戏剧化教学法对汉语成语理解的作用研究
Get PDF[EN] Chengyu are essential to Chinese language and culture. They condense ancient Chinese wisdom in a story of four characters and are usually challenging for international students. In this research, a mixed method employing quantitative and qualitative techniques is adopted to
investigate how using drama to perform the stories associated with the Chengyu might boost students’
understanding of them. The research was conducted at the language school in La Coruña, Spain, with
20 students aged 14-60, thirteen females and seven males of A1/HSK1 Chinese language level. The
control and experimental groups comprised ten students who had to learn the same five Chengyu.
One week after they learned the Chengyu, both groups took the same test to evaluate the degree of
understanding of the five Chengyu. Statistical results show that students in the experimental group
outperformed the ones in the control group. Therefore, we may argue that drama significantly helped
students understand Chengyu.[ES] Los Chengyu son esenciales para el idioma y la cultura chinos. Condensan la
sabiduría antigua en una historia de cuatro caracteres y suelen ser un desafío para los estudiantes
internacionales. En esta investigación, utilizamos un enfoque de métodos mixtos que emplea técnicas
cuantitativas y cualitativas para investigar cómo el uso del teatro para representar las historias
asociadas con los Chengyu ayuda a facilitar la comprensión de los estudiantes sobre ellos. En este
artículo, llevamos a cabo una investigación en la Escuela Oficial de Idiomas (EOI) da Coruña en
España con 20 estudiantes de entre 14 y 60 años, 13 mujeres, 7 hombres de nivel de idioma chino A1/
HSK1. Los grupos de control y experimental estaban compuestos por diez estudiantes que tenían que
aprender los mismos cinco Chengyu. Una semana después de haber aprendido los Chengyu, ambos
grupos realizaron la misma prueba para evaluar el grado de comprensión de los cinco Chengyu. Los
resultados estadísticos muestran que los estudiantes del grupo experimental superaron a los del
grupo de control. Por lo tanto, podemos argumentar que el uso del teatro ayudó significativamente a
los estudiantes a comprender el Chengyu.[ZH] 成语在中国的语言和文化中扮演着至关重要的角色，它们将中国传统智慧浓缩在四

Oviedo´s union headquarters: two projects, one powerful architecture
Get PDF[ES] La Organización Sindical Española fue una de las instituciones más importantes del franquismo, por
ello, sus sedes (o Casas Sindicales) formaron parte de lo que entendemos como la “arquitectura oficial” del momento.
En el caso asturiano, conservamos dos proyectos realizados en contextos completamente diferentes, lo que nos permite
analizar y conocer la evolución tanto del panorama arquitectónico del momento como de la propia OSE. Especialmente,
es relevante la obra definitiva, realizada en 1954, pues confirmó el comienzo de un tiempo nuevo en Asturias.[EN] The Spanish Union Organization was among the most important institutions during dictator Francisco
Franco´s regime. This meant its buildings were considered part of what is now called the “official architecture” of
the time. Two projects for the Union Headquarters’ building were drawn up in Asturias in two very different contexts,
providing an opportunity to analyze the evolution from an architectural and organizational point of view. The building
of the final project, finished in 1954, confirmed the start of a new era for Asturian unionism
Emerging sustainability themes in the hospitality sector: A bibliometric analysis
Get PDF[EN] This paper presents a bibliometric analysis of 837 publications on sustainability in the hospitality sector, specifically
in hotels and restaurants, covering the period from 2010 to 2023. The study assesses the principal
research themes and applied methodologies. The study examined three periods: pre-COVID-19, COVID-19, and
post-COVID-19. The authors conducted a bibliometric study of journals included in the Web of Science related to
the field over the past 14 years. The analysis was carried out through comprehensive indexing of articles and the
application of the bibliometric research tool SciMAT. Specifically, a productivity map and a science map are
presented, inferring potential lines of research. The results reveal key trends in sustainability research, highlighting
predominant themes such as ‘behaviour’, ‘consumers’, ‘business big data’, ‘marketing’, ‘perceived value’,
‘CSR’, ‘local food’, ‘over-tourism’ and ‘SDG’, while a deeper understanding of ‘sustainable communication’,
‘environmental marketing strategy’, ‘green spaces’ and ‘consumer preferences’ were lacking. Addressing these
issues could motivate the development of a more positive attitude toward sustainable travel. In terms of
methodologies, there was a noticeable lack of data mining, neuromarketing, and co-word analyses. This paper
provides clarity on new and necessary approaches and business models to provide resilience to the sector and to
involve clients in the travelling experience.SIThis study is supported by REMODEL project which is funded by the European Union's Horizon Europe research and innovation programme under grant agreement No 101079203
The battle for the narrative of democratic historical memory in the educational system: when history hides the past
Get PDF[ES] En este artículo se presentan los resultados de la investigación sobre el conocimiento que tienen actualmente los jóvenes que han terminado Educación Secundaria en España respecto a la represión de la Guerra Civil, la represión franquista y la lucha antifranquista. Se ha utilizado una metodología mixta, triangulando instrumentos cualitativos (entrevistas y grupos de discusión) y cuantitativos (cuestionario). Los resultados muestran que no siempre se llega a estos temas o se dan por encima, y que los contenidos desarrollados en los libros de texto y materiales curriculares aún mantienen silencios, versiones tergiversadas o equidistantes y ocultamientos deliberados. Se concluye que es necesario disputar el relato de una memoria histórica democrática de forma rigurosa y extensa en el currículum escolar frente a la presión de la ultraderecha en su actual “batalla cultural” contra la memoria y ayudar a reconstruir un currículo contrahegemónico, que tome en cuenta a las víctimas que han quedado en los márgenes de la historia, para que “su nombre no se borre de la memoria” de las futuras generaciones.[EN] This article presents the results of research on the knowledge that young people who have completed secondary education in Spain currently have about the repression of the Civil War, Franco’s repression and the anti-Franco struggle. A mixed methodology has been used, triangulating qualitative (interviews and discussion groups) and quantitative (questionnaire) instruments. The results show that these issues are not always dealt with or are glossed over, and that the contents developed in textbooks and curricular materials still maintain silences, distorted or equidistant versions and deliberate concealments. It is concluded that it is necessary to dispute the account of a democratic historical memory in a rigorous and extensive way in the school curriculum in the face of pressure from the ultra-right in its current “cultural battle” against memory and to help rebuild a counter-hegemonic curriculum, which takes into account the victims who have been left on the margins of history, so that “their name is not erased from the memory” of future generations.S
