Authors: Avilés González Bladimir , Insunza Boloña Florencia , Barrientos Delgado Jaime
Published: August 2024

En Chile, las personas no binarias han sido invisibilizadas por el sistema sexo-género, siendo homologadas en la categoría trans binaria, lo que dificulta la comprensión de sus vivencias subjetivas e identitarias. Este estudio busca conocer y diferenciar cómo las personas trans (binarias) y personas no binarias de Santiago de Chile responden al prejuicio de género, identificando los efectos en identitarios y psicológicos. La población estuvo conformada por personas trans binarias, no binarias y por profesionales de la salud que trabajan con dichas poblaciones. Se realizaron cuatro focus group en el que participaron un total de 22 personas y 15 entrevistas semiestructuradas individuales . Tras un análisis mediante la Teoría Fundamentada se identifica un prejuicio explícito hacia las personas trans binarias y un prejuicio mayoritariamente simbólico hacia personas no binarias. Existen diferencias en las estrategias de afrontamiento del prejuicio, aunque, a nivel psicoterapéutico se reportan expresiones sintomáticas y clínicas similares: depresión, ansiedad, desesperanza e ideación suicida.

Football-Manía: el origen de las canchas de fútbol en Valparaíso. 1882-1920
Authors: Arteche López Pablo Eduardo
Published: August 2024

El año 1882 se fundó en Valparaíso el primer club de fútbol del país, iniciándose así una primera etapa organizacional, que concluyó con la creación de la Football Association of Chile en 1895. Sin embargo, a mediados del año 1896, el periódico La Unión anunciaba que en la ciudad puerto se había desatado el fenómeno de la “Football-Manía”, aludiendo a la acción de jóvenes que seguían buscando en cualquier espacio disponible la posibilidad de desarrollar informalmente esta nueva práctica deportiva. En este artículo se presenta la investigación realizada que logró determinar dónde se establecieron las primeras canchas para esta emergente actividad futbolística en el contexto urbano de Valparaíso a finales del siglo XIX e inicios del XX, antes de la construcción de la primera infraestructura mayor realizada con motivo del Campeonato Sudamericano en 1920. Para efectos de determinar las respectivas localizaciones se recurrió a la revisión de fuentes escritas, gráficas y cartográficas, las cuales pudieran establecer con certeza las ubicaciones buscadas, para luego, a través de estos descubrimientos, revisar cómo fue el panorama del origen y primer desarrollo del lugar del fútbol en la extensión urbana de Valparaíso y sus alrededores.
Centro de interpretación del agua: recuperación y puesta en valor del puente ferrocarril “El Manzano”
Authors: Renis Barrientos Dominique
Published: August 2024

El puente El Manzano es una antigua estructura ferroviaria construida entre los años 1911 y 1914 como parte de la línea Puente Alto - El Volcán, ubicado sobre el estero El Manzano en la localidad homónima de San José de Maipo. Jugó un papel vital en la conectividad local, sin embargo, en la década de los 80, el implacable avance de las tecnologías lo dejó obsoleto, llevándolo al deterioro gradual y, finalmente, al desmantelamiento de sus componentes. Si bien este monumento posee un valor histórico y patrimonial significativo, su entorno actual limita su apreciación en toda su magnitud. El principal punto de observación se encuentra en el puente carretero que discurre paralelo al ferroviario, desde esta perspectiva, se ve obstaculizada tanto la contemplación del puente, como la posibilidad de que sea habitado y cumpla su función esencial de ser cruzado, dada su naturaleza arquitectónica.
Se propone el proyecto titulado “Centro de Interpretación del Agua: Recuperación y Puesta en Valor del puente ferrocarril El Manzano” (proyecto de título para optar al título de Arquitecta en la Universidad de Chile) con el objetivo de restaurar y realzar el puente junto a su entorno, a través de tres estrategias principales. En primer lugar, rehabilitar la infraestructura después de un análisis detallado, para garantizar intervenciones adecuadas y prepararla para el centro de interpretación. En segundo lugar, instalar una pasarela sobre el puente para recuperar su función original y, al mismo tiempo, servir como sede de programas del centro. Por último, buscar integrar el monumento con el entorno mediante intervenciones paisajísticas, que ofrezcan diversas perspectivas del puente y el estero, vinculándose con la actividad acuática de la zona.
La cuna del “Nuevo Peruano”: Cultura física y eugenesia en el proyecto social de la hacienda Chiclín (1890 - 1926)
Authors: Ávila Juárez Mauricio
Published: August 2024

Tras la derrota peruana en la Guerra del Pacífico, son diversos los discursos intelectuales que muestran una urgencia general por la ausencia de cuerpos viriles para el Perú, y esto motivó una serie de reformas sociales durante el proceso de Reconstrucción Nacional. Este artículo ilustra el proyecto social de la hacienda Chiclín, ubicado en el norte peruano (La Libertad), y dirigido por Rafael Larco Herrera y orientado a este objetivo de “reformar” y civilizar la raza peruana. Motivado por las ideas del darwinismo social, Larco encaminó su hacienda para ser una “hoja en blanco” para refundar una sociedad utópica, y utilizó los deportes como herramienta para forjar un “nuevo peruano”. A través del análisis de los discursos, obras y proyectos de Larco Herrera en Chiclín, y el impacto de la Guerra del Pacífico en su juventud, podemos evidenciar el enfoque eugenésico y paternalista en su labor social. Larco buscó promover la salud física y moral de los trabajadores, fomentando la cultura física y el deporte como medios de disciplina, civilización y progreso para el Perú.

Instructors’ Interpersonal Interaction with Students in a Tanzanian University: A Study of Students’ Perceived Interpersonal Characteristics of Instructors
Authors: Kavenuke Patrick Severine
Published: August 2024

The study examined students’ perceptions of their instructors’ interpersonal characteristics. I used a sample of 593 final-year students who completed the questionnaire. The study aimed to (i) establish the level of instructors' interpersonal interactions with final-year students, (ii) examine the relationships that exist among instructors’ interpersonal characteristics, and (iii) examine how students’ GPAs influence their perceptions of instructors’ interpersonal characteristics. Results indicated that students scored relatively higher in the Leadership and Understanding aspects. On the contrary, students scored below the mean average in Uncertain, Admonishing, Dissatisfied, and Strict aspects. Mixed results were observed in the correlation among aspects of instructors’ interpersonal characteristics. While some aspects had a positive and large correlation, as the model for instructors’ interpersonal behaviour suggests, others indicated a positive correlation when the model advocates that such aspects hardly portray similar instructors’ interpersonal behaviour. Regarding students’ GPAs, findings indicated that students’ GPAs have a significant relationship with their perceptions of instructors’ interpersonal characteristics in all aspects of the influence sector, implying that students with low GPAs perceived their instructors to possess negative interpersonal characteristics. The study concludes that as instructors interact with students, it is important to advise, encourage, and warn students politely rather than criticising, reprimanding, or correcting them in an unfriendly manner and by being harsh.
Breaking new ground: Using and evaluating collaborative autoethnography to enhance teacher adaptability in higher education
Authors: Valiente-Riedl Elisabeth , Robinson Helena , Fletcher Jennifer , Cejnar Leela
Published: August 2024

The combined impacts of dramatic social, industrial, environmental, and technological changes on higher education demand continuous adaptation and reinvention of teaching approaches. We evaluate collaborative autoethnography as a methodology that permits educators to share and interrogate their practices, activating critical reflection, experimentation, and just-in-time teaching innovation, while also cultivating a community of learning. As four education-focused academics teaching into a senior undergraduate experiential learning program, we experimented with collaborative autoethnography to cooperatively assess and develop our teaching practice during the disruption of the COVID-19 pandemic. Our experiences suggest collaborative autoethnography's strong potential to amplify teachers’ critical reflection and formally support professional development, including through the formation of productive collegial networks. However, we also encountered methodological challenges. These include ethical dilemmas with collaborative autoethnography research conducted in emergency contexts, as well as concerns over the integrity of the reflection process, both in terms of reaching consensus in the interpretation of different narratives and the sufficiency of voices included and excluded in authorship. Ultimately, the strengths and challenges of collaborative autoethnography represent a critical opportunity for teachers in higher education to contribute to further developing this tool not only as a research methodology, but also as a professional development process.
Informing Teaching and Learning Practices in Higher Education: Reflections from Engaging in Home-Schooling
Authors: Attree Katherine , Gersbach Katrina , Gumbleton Kylie , Auhl Gregory
Published: August 2024

Using a collaborative autoethnographic approach, this paper draws on the experiences of four multi-disciplinary Australian academics who engaged in home-schooling during the 2020 and 2021 COVID-19 lockdowns to answer the research question, ‘how might our experiences of engaging in home learning inform our practice in higher education?’ The reflections encompassed our experiences in engaging with unfamiliar technology, equity issues, pedagogical aspects of online delivery, teacher presence, communication, well-being and our own cognitive and emotional responses. We considered the implications of this rich learning experience for our own learning and teaching practice as university academics. Our key findings are the need for a consistent, scaffolded, and supported approach to delivery of technology, consideration of its affordances, a flexible approach to student engagement that considers equity and contextual issues, and a focus on well-being and support. Limitations of this study include the single institution focus and the limited generalisability of auto-ethnographical research.

Published: August 2024

To expand knowledge about native species in southern Brazil, different types of extracts from the thin vinaceous bark of A. angustifolia and fragments of branches of P. crenata were evaluated. These were crushed and kept for fifteen days in contact with hydroalcoholic solutions at 70 % v/v and ethanolic (96 % v/v), seven days in the cold aqueous extract, and through the decoction process for 10 min. Afterward, they were evaluated at concentrations of 1.0 %, 2.5 %, 5.0 %, 10.0 %, and 20.0 % v/v on the mycelial development of the phytopathogenic fungi Colletotrichum gloeosporioides, Botrytis cinerea, and Sclerotinia sclerotiorum. The levels of phenolic compounds and total flavonoids were evaluated, and the alcoholic extracts of A. angustifolia had the highest total phenolic content. The main phenolic compounds identified in the P. crenata extract were resveratrol, followed by herperidin, rutin, ferulic acid, and kaempferol, and the main chemical compounds identified in the extracts of A. angustifolia were quercetin, rutin, ferulic acid, kaempferol, and gallic acid. A. angustifolia extracts and P. crenata, during the decoction, were more effective in controlling the phytopathogens C. gloeosporioides and B. cinerea from a concentration of 5 % v/v. The fungus S. sclerotiorum was moderately inhibited in hydroalcoholic extracts at 70 % v/v of P. crenata and A. angustifolia at 1.0 % and 2.5 % v/v concentrations. Effectively controlling these phytopathogenic fungi of agricultural importance confers importance on the conservation of these native species of socio-biodiversity in the Atlantic Forest in southern Brazil.

The immune system is characterized by uni versality, meaning that nonspecific defense mech anisms are present in all living organisms, from the
simplest forms to the most evolved ones, because
they all have their infectious agents, microbial (bac terial, fungal, parasitic) and viral. These invisible
enemies exerted selective pressure over time, and
in parallel with their increased infectivity and vir ulence mechanisms, the defense mechanisms also
evolved due to host-parasites coevolution [1-2]. The
immune system is best studied in animals, especial ly the adaptive or specific immunity of vertebrates,

Objectives: Colorectal cancer (CRC) is a tumor with a constantly increasing incidence. Among the diagnostic approaches studied, biomarker combinations have so far performed better than single biomarkers. The present study aims to investigate the potential contribution of several such combinations to the noninvasive diagnosis of CRC. Methods: Serum levels of a cytokine (IL-8), two cell adhesion molecules (ICAM-1 and P-selectin-Psel) and a matrix-metalloproteinase (MMP-7) were measured by ELISA (Enzyme-Linked Immunosorbent Assay) in thirty-one CRC patients and thirty-three healthy controls. The biomarker potential of combinations between these molecules was tested by logistic regression. Results: The tested combinations had good biomarker potential, with AUCs (Areas under the curve) between 0.841 and 0.857, sensitivities (Sn) ranging from 0.77 to 0.87, and specificities (Sp) between 0.7 and 0.85. The best performance was recorded for the combination IL8-Psel-MMP7, with an AUC of 0.857, Sn of 0.85, and Sp of 0.80. For the early stages of CRC, the same combination had an AUC of 0.850, Sn of 0.81, and Sp of 0.85. Conclusions: The findings of this study underscore the significant potential of biomarker combinations in the diagnosis of CRC, particularly in the early stages. The IL8-Psel-MMP7 combination, in particular, demonstrates the highest biomarker capability, offering a promising avenue for non-invasive diagnosis of CRC.
A High Gain, Low Power Operational Transconductance Amplifier Capable of Recording and Processing ECG Signals
Authors: Xuan Zhengnan
Published: August 2024

Based on high output resistor current mirrors and differential pair inputs, a new operational transconductance amplifier (OTA) is designed in this paper that can collect, filter, denoise and amplify electrocardiogram (ECG) signals. The OTA is designed on a 0.18μm CMOS process with a supply voltage of 1.8V. In this experiment, the ECG signal generated by the human model is first simulated, which has a noise of 50 Hz from electromagnetic interference, especially the electrical power lines. The differential input pair is then connected to the model, and it is proved that it can denoise the common-mode noise. Finally, the designed OTA is connected to the manikin, and the experimental results are compared with the traditional OTA. The design achieves a differential-mode gain of 43.56dB and a common-mode gain of -31.36dB while maintaining a differential input voltage swing of 1Vpp. Experimental results show that the OTA can denoise and amplify the ECG signal without distortion.

PID Optimization Method Based on Heuristics Algorithm And Q-Learning
Authors: Li Yuang
Published: August 2024

Proportional-integral-derivative (PID) control is a feedback control algorithm that adjusts the output signal through a combination of three control terms, proportional, integral, and differential, and is used to stabilize the actual output of the system close to the desired value. Heuristic algorithms are a class of intelligent problem-solving methods that optimize the solution using rules and trial-and-error learning; Q-learning is a reinforcement learning algorithm that focuses on decision-making in the Markovian decision-making process and achieves the optimal strategy by continuously learning and updating the value function. As people's requirements for the accuracy of various control systems increase, the requirements for the stability and robustness of PID control algorithms also increase. The traditional Ziegler-Nichols method to find PID parameters can no longer meet people's needs well, and people want to find more stable PID parameters faster. This article introduces different heuristic algorithms, such as particle swarm optimization algorithm and Q-learning algorithm for optimizing PID parameters in different systems. The effect of optimization of different algorithms is also analyzed.
LSTM-Based Gasoline Price Prediction - An Example of Gasoline 95# in Beijing
Authors: Zeng Lingyue
Published: August 2024

Gasoline, as one of the indispensable energy sources in the global economy, the stability of its price has an important impact on national energy security and economic development. This study aims to improve the accuracy of gasoline price prediction through the use of Long Short-Term Memory Network (LSTM). By collecting and analyzing the historical price data of No. 95 gasoline in Beijing, the author constructed a prediction model based on LSTM, which is particularly suitable for dealing with long-term dependence in time series data. By comparing their performance to the traditional Recurrent Neural Networks (RNN) and Convolutional Neural Networks (CNN), LSTM demonstrates its advantages in processing complicated time series data. The validity of the model is verified by several evaluation metrics, including mean square error (MSE), root mean square error (RMSE), mean absolute error (MAE), and mean absolute percentage error (MAPE). The results of the study indicate that the LSTM model shows high accuracy and reliability in predicting gasoline prices. In addition, future work will explore the introduction of multivariate analysis and hybrid network models to further the accuracy of the predictions and its generalization ability.
Application Of Terahertz Electromagnetic Waves in The Field of Detection
Authors: Liu Run
Published: August 2024

Among all kinds of electromagnetic waves, terahertz (THz) waves are those with frequencies varying from 0.1 to 10 THz (with wavelengths ranging from 3000 to 30x10-6 m). Millimeter waves in the long wavelength range overlap with electromagnetic waves, as well as infrared light in the short wavelength range. The THz gap in the electromagnetic spectrum is the crossover between electronics and photonics, and between macroscopic classical theory and microscopic quantum theory. The THz wave band has the same characters as spectrum of substances such as semiconductors, plasmas, organisms, and biomolecules, having the characteristics of quantum energy and low blackbody temperature. The time-domain spectral signal-to-noise ratio of THz is very high, making it excellent for applications involving images. Because of the extremely large instantaneous bandwidth (0.1-10THz), high-speed transmission is possible. Therefore, utilizing THz can deepen and broaden humans’ knowledge of some fundamental scientific issues in physics, chemistry, astronomy, informatics, and life sciences. At present, technology related to THz wave is widely used in temperature sensors, biosensors, communication, astronomy, and safety inspection fields.

Abstract: Literacy and numeracy are two important skills that every individual must have, especially in the current digital era. However, SDN 02 Mayangan is classified as a school with low literacy and numeracy skills. This can be seen from students in high classes still not being able to complete multiplication operations, students' literacy levels are relatively low, and students feel bored in class learning. Appropriate learning media and integration of local wisdom in learning can help improve student literacy and numeracy. However, most teachers have not been able to create learning media that suits students' needs and is based on local wisdom. Thus, there is a need for training and assistance in creating local wisdom-based learning media for teachers. The method for implementing this community partnership program uses Service Learning (SL). The SL method consists of four steps, namely investigation, preparation, action, and reflection. With this community service activity, teachers can improve their abilities in compiling and applying digital media, snakes and ladders media, and storybooks based on local wisdom to optimize students' literacy and numeracy skills. In this activity, 82% of participants felt very satisfied with the material presented and 80% of participants felt very satisfied with the method used. Keyword: learning media; local wisdom; literacy; numeracy Abstrak: Literasi dan numerasi merupakan dua keterampilan penting yang harus dimiliki oleh setiap individu, terutama di era digital saat ini.
