Vivencias queer en el aula: bienestar autopercibido del profesorado LGBT+ gallego
Authors: Amigo Ventureira Ana María , Garrido López Xandre
Published: September 2023

INTRODUCCIÓN. El bienestar psicosocial del cuerpo docente es a la vez un fin en sí mismo y un requisito ineludible para mejorar la docencia y el clima en las aulas. Un factor que influye sobre este bienestar es la pertenencia a colectivos discriminados socialmente como el LGBT+. Si bien se han desarrollado numerosos estudios relacionados con las personas LGBT+ en el sistema educativo, estos se centran en su mayoría en el alumnado. MÉTODO. Para determinar la influencia de la LGBTfobia sobre el profesorado LGBT+, hemos realizado un estudio de tipo cualitativo, llevando a cabo entrevistas dialógicas no estructuradas a 8 docentes de perfiles diversos. RESULTADOS. Hemos determinado que el nivel de bienestar del profesorado se ve influido por las distintas formas en las que la LGBTfobia estructural se manifiesta en el sistema educativo. El miedo a perder el puesto de trabajo, al mobbing o la confrontación con familias LGBTfóbicas impide a parte de este colectivo vivir abiertamente su sexualidad o identidad, lo cual tiene un impacto severo sobre su salud mental y desempeño. Los efectos negativos de estas conductas discriminatorias son magnificados cuando no cuentan con una red de apoyo, en forma de grupo LGBT+ dentro del centro o contando con el respaldo de una asociación. DISCUSIÓN. Los resultados señalan que la LGBTfobia debe ser afrontada por parte de las instituciones con medidas específicas y eficaces para alcanzar la plena inclusión del profesorado LGBT+. El cumplimiento real de la legislación vigente en esta materia y la formación efectiva del cuerpo docente en atención a la diversidad de género y orientación sexual sobresalen como elementos fundamentales en pos de este objetivo.

Published: September 2023

Abstract: Objectives: The aim of this study is to examine how humancentered design (HCD) as a platform for co-production might function to explain community health volunteer (CHV) motivation in self-directed and self-funded community health activities. Sustaining engagement has been difficult for CHVs who lack monetary incentives, expense reimbursement, and are rarely given opportunity to give their own voice to local health priorities. Design: Qualitative study utilized focus group discussions 12 months post intervention and included both an inductive and deductive level of analysis. Setting: Three community health units (CHU) representing Kenya's diversity were selected with the local Ministry of Health including peri-urban slum, rural agrarian, and a unit where informal day labor and rented housing was the norm. Participants: The participants were selected according to Kenya's community health strategy norms and had previously had the standard basic community health training. Intervention: A 3-day training rooted in HCD utilized multiple quality improvement tools (asset mapping, root cause analysis, key drivers) in order to help CHVs uncover unarticulated community needs and assumptions and encourage behavior change. Action plans with Plan-Do-Study-Act cycles were tracked longitudinally. Results: Key themes were self-interest, common goal, gratitude/indebtedness. Additional thematic analysis identified altruism as supporting sustained engagement. Conclusions: This study supports HCD as a platform for sustained CHV engagement. It builds the evidence for self-interest, common goal, and gratitude/indebtedness as sustaining factors. These factors are also seen in process-based theories that operationalize and measure trust building reciprocity cycles that mirror the iterative P-D-S-A cycles seen in HCD.

Abstract: Background: Mental health care is a top clinical concern for modern Puerto Rico, especially given a dramatically changing economic landscape paired with recurrent natural disasters. Youth are particularly at-risk due to long-term impacts of toxic stress and adverse childhood experiences on health and development. Objectives: Here we present a novel clinician–community-educator–scientist partnership to address Puerto Rican youth mental well-being and wellness. We deployed pilot health workshops within the Boys & Girls Clubs of Puerto Rico to build youth mental health conceptual understanding and competencies in stress recognition and management. The work in progress herein evaluates acceptability and feasibility of our curricular model. Methods: Dialogue with community stakeholders guided curricular design of workshops for youth ages 6 to 13 and older. Prior to implementation, educators and volunteers attended a 1-day training on educational strategies. Workshop success was evaluated using qualitative approaches (i.e., narrative feedback, educator and volunteer reflections, youth Talking Drawings) to assess youth engagement, youth conceptual health understanding, and educator/volunteer impressions of feasibility and impact. Results: Initial findings indicate high acceptability and feasibility of our curricular model. Youth engagement and enthusiasm were noted in educator feedback and continue to be sustained post-workshop. Preliminary analysis shows accompanying increases in youth conceptual mental health understanding, particularly for 6- to 12-year-olds in recognition of stress and healthy coping mechanisms. Reciprocal gains were observed for volunteers. Conclusions: Activities have evolved into a formal partnership called Semilla , which features expanded analysis of mental well-being and wellness outcomes. Our collaborative model continues to engage Puerto Rican youth in the science of their well-being.
Staging Forgetting: How Botho Strauß and Heiner Müller Dislocate A Midsummer Night’s Dream
Authors: Döring Tobias
Published: September 2023

Abstract: Comedy may well be the generic form most intensely tied to the contemporary. If contemporariness, as defined by Giorgio Agamben, is “that relationship with time that adheres to it through a disjunction and an anachronism,” comedy stages this relationship by making such disjunctions the prerequisite of laughter while subjecting its protagonists to confusions and anachronisms, in the words of Shakespeare’s Puck, “that befall preposterously” (3.2.121). How, then, does comedy travel through time? How may its disjunctions be displaced to very different circumstances? And how, specifically, can it be rewritten so as to contest the pastness of the past? This article sets out to explore these issues through a reading of two little known, but highly resonant and symptomatic, German stage plays that engage, in rather different ways, with A Midsummer Night’s Dream : whereas Heiner Müller’s Waldstück (1969) relocates the erotic and political entanglements of Shakespeare’s Athens to a workers’ recreation home in the German Democratic Republic, Botho Strauß’s Der Park (1983) tries to reimagine mythic characters and their magic charm under conditions of West German banality. Both merit comparison and study as their project is less directed at remembering and retrieving powerful Shakespearean legacies than marking loss and making us forget their power—comedies which, in Agamben’s sense, hold their gaze on their own time so as to perceive its darkness.
Adding It Up: Investing in Contraception and Maternal and Newborn Health, 2017—Estimation Methodology
Authors:   Guttmacher Institute, Darroch Jacqueline E.
Published: September 2023

This report provides methodological details on the estimates presented in Adding It Up: Investing in Contraception and Maternal and Newborn Health, 2017 and related publications, and includes detailed national and regional data. Adding It Up is an ongoing Guttmacher Institute project in which researchers estimate the need for and the use, costs and impacts of various sexual and reproductive health services for developing countries. Estimates have thus far been produced for 2003, 2008, 2012, 2014 and 2017; 2016 estimates focusing on adolescents are also available. While the basic Adding It Up methodology remains unchanged, this report details recent revisions to some of the estimation approaches.

Authors:   Guttmacher Institute, Biddlecom Ann , Riley Taylor , Darroch Jacqueline E. , Sully Elizabeth A. , Kantorová Vladimíra , Wheldon Mark C.
Published: September 2023

Key Points This report presents scenarios of adolescent contraceptive use through 2030 to highlight the potential impact and costs associated with overall increased contraceptive use among adolescents and an increased use of long-acting, reversible contraceptives (LARCs), specifically. Under a scenario that assumes the most likely level of modern contraceptive use to be reached in a particular year (median values of probabilistic projections), the number of adolescent women using modern contraceptives in developing regions would reach 19.8 million in 2030, and 57% of adolescent women would have their need for modern contraception met. The total annual cost of services in 2030 for the projected 19.8 million modern method users would be an estimated $310 million. The cost would be lower, at $275 million, if 20% of adolescent women using short-acting methods were to choose LARCs. An estimated 7.1 million unintended pregnancies would be averted under this scenario. Because LARCs are highly effective, a shift toward use of these methods would avert an additional 300,000 unintended pregnancies. Under a scenario with accelerated growth in modern contraceptive use among adolescent women in developing regions, the number of modern method users would reach 27.1 million in 2030, and the proportion of adolescent women whose need for modern contraception would be met would rise to 79%. Contraceptive services for the 27.1 million modern method users in 2030 would cost an estimated $412 million. The cost would drop to $365 million under an assumption of increased LARC use. In 2030, an estimated 9.6 million unintended pregnancies would be averted under this accelerated growth scenario, and an additional 400,000 unintended pregnancies would be averted with a shift to LARC use.
Wavefront control capability in a modal lens with segmented circular peripheral electrodes
Authors: Tabourin Loïc , Brousseau Denis , Thibault Simon , Galstian Tigran
Published: September 2023

We report the detailed investigation of the capability of an electrically tunable liquid crystal lens (TLCL) to dynamically generate various wavefront shapes. The TLCL operates in the modal-control mode with a peripheral circular electrode divided into eight individually controlled segments. This segmentation allows producing a rather rich set of influence functions. We characterize these functions and the crosstalk between them by adjusting the voltage and the frequency of electrical signals applied to different electrode segments. Various wavefronts are produced in a closed-loop control mode and described using Zernike polynomials. The dynamical response of the lens is also briefly investigated. Obtained results may be used to design different adaptive optical systems where a dynamic wavefront control is required.
Single-active-element demultiplexed multi-photon source

Published: September 2023

Temporal-to-spatial mode demultiplexing routes non-simultaneous events
of the same spatial mode to distinct output trajectories. This
technique has now been widely adopted, because it gives access to
higher-number multi-photon states when exploiting solid-state quantum
emitters. However, implementations so far have required an
always-increasing number of active elements and are therefore rapidly
facing resource constraints. Here, we propose and demonstrate a
demultiplexing approach that uses only a single active element for
routing to, in principle, an arbitrary number of outputs. We employ
our device in combination with a high-efficiency single-photon source
based on a quantum dot, and measure up to eight demultiplexed highly
indistinguishable single photons. We discuss the practical limitations
of our approach, and describe in which conditions it can be used to
demultiplex, e.g., tens of outputs. Our scheme thus provides a path
for the preparation of resource-efficient larger-scale multi-photon
sources.
ARIAS: An AR-based interactive advertising system
Authors: Wang Qiujiao , Xie Zhijie
Published: September 2023

In this paper, we present an interactive advertising system based on augmented reality(AR) called ARIAS, which is manipulated with gestures for displaying advertising videos. Two-dimensional markers are defined in the system. The system captures the frame data through the camera in real time, uses OpenCV library to identify the predefined markers, and calculates the pose of markers captured by the camera. With OpenGL library, a virtual cubic model is created at the position of the marker, and thus videos or images are displayed on the six faces of the cube. The virtual cube, together with the original frame data collected by the camera, is displayed in the interactive window to achieve the augmented reality effect. Customers are accessible to various advertising content by observing the marker from different positions. The system, meanwhile, supports gesture operation in order to make the customers pay attention to the content they are interested in with one hand. The MediaPipe Hand framework is used to extract the landmarks of hands, based on which, a series of gestures are designed for interactive operation. The efficiency and accuracy of the system are tested and analyzed with the result, indicating that the system has high reliability and good interactiveness. This system is open at https://github.com/wanzhuxie/ARIAS/tree/PLOS-ONE.

Published: September 2023

A field experiment was conducted at the Research Farm of the ICAR-Indian Institute of Soil Science, Bhopal (India) to study influence of different integrated nutrient management (INM) modules on soil potassium (K) fractions. The experiment comprised with twelve treatments laid out in randomized block design (RBD) with three replications under maize-chickpea cropping sequence. The treatments included general recommended dose (GRD), soil test crop response (STCR) dose; combinations of inorganic and organic inputs and only organic modules. The soil samples were collected at crop harvest and analyzed for various K fractions viz., water soluble-K, available-K, exchangeable-K, HNO3-K, lattice-K and total-K. The results indicated that potassium fractions were significantly (p = 0.05) affected by different treatments. Different INM modules significantly enhanced significantly K availability in soil. Among various INM modules studied, treatment 11 (application of 20 t ha-1 FYM in maize with 5 t ha-1 FYM every year in chickpea) proved most beneficial for improving the soil K fractions. Findings of this type are important for K fertilizer management during crop production in areas with low soil fertility.
‘Inanimate Objects’: Human consequences of Australia’s commodified approach to migrant workers during COVID-19
Authors: Berg Laurie , Farbenblum Bassina
Published: September 2023

The Australian government has long treated migrant labour as a commodity, a ‘tap’ to be turned on and off in accordance with government or employer perceptions of the labour market. This article examines the Australian government’s policies concerning migrant workers during COVID-19, against the backdrop of its failure to take any meaningful steps to address systemic migrant exploitation over the past decade. It then considers the devastating human consequences of these policies during the first pandemic lockdowns, based on empirical data from over 6,100 temporary migrants collected in mid-2020. The data demonstrate migrant workers’ inability to pay for essential needs (including food and medical care); their lack of access to secure or emergency housing as well as emergency support in the form of cash or food; and their experiences of racism, discrimination, and social exclusion during the pandemic. We conclude that Australia’s commodified approach to migrant workers and acquiescence to exploitation reflected a deeper disavowal of migrants’ humanity and rights. This lens explains the apparent contradiction in which the government first denied or disregarded its legal and moral responsibilities towards them during the immediate crisis posed by the pandemic, while at the same time courting their labour in the context of skills shortages during and after the pandemic.
‘Now More Than Ever, Survivors Need Us’: Essential labouring and increased precarity during COVID-19
Authors: Schwarz Corinne , Britton Hannah , Nay Eden , Holland Christie
Published: September 2023

During the earliest waves of the COVID-19 pandemic, much media and public discourse focused on the effects of increasing precarity on already vulnerable populations. As in-person work added a layer of viral risk and unemployment drastically exacerbated economic precariousness, the category of ‘essential worker’ gained new prominence in these conversations. In this paper, we focus on the complicated relationship between two groups of workers depicted as marginalised and exploited to different degrees during COVID-19: trafficked persons and anti-trafficking service providers. Though media coverage did not conflate these groups, it applied a capacious understanding of precarious labour and structural inequalities that encapsulated different types of essential work. We draw on media produced by frontline anti-trafficking and sex workers’ rights organisations between March and May 2020. Even with renewed attention to macro-level harms, many publications still emphasised individualism over collectivity. This emphasis on singular organisational representatives—frontline workers—as heroic rescuers mirrored larger, normative anti-trafficking discourses. At the point at which the ‘new normal’ was nowhere in sight, COVID-19 served as a flashpoint to reconsider current intervention strategies and instead emphasise a critique of precarious labour along multiple vectors.

Don’t Step Across This Line: Crossing Borders in Little Men
Authors: Buesa Andrés
Published: September 2023

This article explores the role of borders in contemporary cities and their implications in social stratification in Ira Sachs’ Little Men (2016). Drawing on border theory and its application to film studies, it first situates the movie within the category of the “border film”, insofar as it focuses on New York urban borders and borderlands as a thematic element; and it uses borders narratively in order to explore the social and racial dynamics between an Anglo family—the Jardines—and their Latino tenants—the Calvellis. From this approach, it then explores the narrative and aesthetic strategies by which the film represents the conflict between the families in terms of a simultaneous process of border building— in the case of the adults—and border crossing—in the case of the children. It ultimately contends that the film, by reaffirming the border between the children in the epilogue, questions the notion of equality that underlies the essentially neoliberal myth of the American Dream.
Systematic Literature Review of Therapeutic Use of Autonomous Sensory Meridian Response (ASMR) and Short-Term ASMR Auditory Training Trial
Authors: Cubelo Christine
Published: September 2023

This thesis consists of 2-parts: a systematic review of current publications on therapeutic use of autonomous sensory meridian response (ASMR), and a within-subjects auditory training trial using ASMR videos. The main intent is to explore ASMR as potentially therapeutically beneficial for those with atypical sensory processing. Many hearing related disorders and mood or anxiety symptoms overlap with symptoms of sensory processing issues. For this reason, inclusion and exclusion criteria of the systematic review were generated in an effort to produce optimal search outcomes, and avoid overly confined criteria that would limit yielded results.

Criteria for inclusion in the review for Part 1 are: (1) adult participants diagnosed with hearing loss or atypical sensory processing, (2) inclusion of measures related to ASMR as a treatment method and (3) published between 2000 and 2022. A total of 1,088 publications were found in preliminary search, and a total of 13 articles met inclusion criteria. A total of 14 participants completed the trial and post-trial questionnaire. Of all responses, 64.29% agreed that the duration of auditory training sessions was reasonable. In addition, 71.43% agreed that the training improved their perception of music. Lastly, 64.29% agreed that the training improved their perception of a primary talker when there are other talkers or background noises present.
Character Education in Shaping a Disciplined and Noble Generation: A Study of Children Aged 4-6 Years at RA Perwanida Brawijaya
Authors: Arin Arini Mubaroroh , Sa'dun Akbar
Published: September 2023

This study aims to uncover the implementation of character education for children aged 4-6 years at RA Perwanida Brawijaya, Pamekasan. The method used is a qualitative approach with descriptive data collection, using the principal and teachers of RA Perwanida Brawijaya as primary data sources, and literature from books and the internet as secondary data. The research findings indicate that character education at RA Perwanida Brawijaya, Pamekasan, is implemented through routine activities, incidental activities, and the "Blessed Friday Charity" program that assist in the development of empathy, care for others, and understanding the significance of giving in Islam. The limitations of this study lie in the implementation of character education at RA Perwanida Brawijaya, Pamekasan. The execution of character education can help children face life's challenges and enhance their future quality of life through the formation of positive attitudes. This character education implementation through routine activities, incidental activities, and school programs allows children to develop good character traits consistent with the values and beliefs instilled in the educational process, becoming an integral part of their personality.
Mangrove biomass and carbon estimates for REDD+ from national forest inventory in two regions of Myanmar

Published: September 2023

Myanmar has the second largest area of mangrove forests in South East Asia while suffering high deforestation rates and forest degradation. However, monitoring results from existing studies in mangrove forests vary widely while specific estimates on carbon density for this forest type
are deficient. Also, data from mangrove inventory plots used for the 2018 Myanmar forest reference level refer only to commercial timber and do not include other carbon pools. The results in this study based on four carbon pools allow for updating the emission factors in mangrove forests expressed
in CO2 from 125.43 ± 15.06 Mg ha –1 to 1 377.07 ± 67.04 Mg ha –1 for Ayeyarwady region (Pyapon, Pathein, Latputta districts) and 1 583.27± 75.18 Mg ha –1 for Tanintharyi region (Kawthaung, Dawei districts) and can be used in (sub)national or
jurisdictional forest reference level for REDD+. In addition, the georeferenced biomass estimates are useful for the calibration of space-based models of biomass estimation.
Analyzing pellet agglomeration in underwater polymer extrusion pelletizers: a numerical simulation study
Authors: Raj Bebhash S. , Chandy Abhilash J.
Published: September 2023

The production of thermoplastic pellets using underwater die-face pelletizers is a widespread process in the thermoplastics compounding industry. One major challenge in this process is pellet agglomeration, which occurs when the polymer is pliable or easily deformed under heat. To tackle this issue, the non-Newtonian flow of a polymer, along with the turbulent flow of heating oil and heat transfer through the die, are modeled using three-dimensional (3D) computational fluid dynamics (CFD) calculations in ANSYS Fluent. The computational model is validated by comparing its predictions of temperature and pressure using two models with and without a slip method, to experimental measurements from an industrial-scale pelletizer, resulting in a maximum error of <3 % for temperature and <16 % for pressure. The efficiency of the underwater die pelletizer is typically evaluated based on the rate at which it produces pellets. Minor variations in operational parameters, such as the inlet mass flow rate and temperature of the polymer, the temperature of the heating oil, and the water temperature, can greatly affect the quality of the final product. Firstly, contours of pressure, velocity and temperature are presented to understand their impact on pellet agglomeration. However, to more specifically link pellet quality, i.e. pellet agglomeration rate, to the input conditions, the study develops a non-dimensional parameter called the pellet agglomeration number (PAN), as a non-linear function of three other non-dimensional numbers: Reynolds number, Euler number, and a non-dimensional temperature. The values of PAN at the exit and inlet are shown to correlate well with the experimentally measured pellet agglomerations, thereby demonstrating the usefulness of PAN in not only differentiating between good and bad pellet quality but also determining apriori the appropriate operating conditions leading to fewer pellet agglomerations in commercial pelletizers.
Application of indocyanine green in the management of oral cancer: a literature review
Authors: Zhou ChuHuan , Nan XinRong
Published: September 2023

Indocyanine green is a cyanine dye that displays fluorescent properties in the near-infrared region. Indocyanine green has good water solubility and can bind to plasma proteins in the body. After binding, it can display green fluorescence when irradiated by near-infrared fluorescence. Owing to its good imaging ability and low side effects, indocyanine green is widely used in the diagnosis and treatment of various tumors. Indocyanine green-assisted sentinel lymph node biopsy helps determine clean tumor boundaries, helps surgeons remove primary tumors completely, assists in microvascular anastomosis in head and neck repair and reconstruction, reduces operation time, evaluates blood perfusion to monitor flap status. In addition, indocyanine green has great potential in photodynamic therapy to specifically kill tumor cells. However, despite the benefits, studies regarding the application of indocyanine green in oral cancer are limited. Therefore, we conducted a literature review to explore the application of indocyanine green in oral cancer to benefit clinicians involved in the diagnosis and treatment of this disease.
Analysis of Cu and Zn contents in aluminum alloys by femtosecond laser-ablation spark-induced breakdown spectroscopy
Authors: Pinjun Li , Zhengye Xiong , Zidong Ma , Jingyuan Guo , Chunxi Wang
Published: September 2023

To enhance the sensitivity of detecting Cu and Zn in aluminum alloys, we incorporated a spark discharge unit into the femtosecond laser-induced breakdown spectroscopy (fs-LIBS) system, forming a femtosecond laser ablation spark-induced breakdown spectroscopy (fs-LA-SIBS) system. We utilized both fs-LA-SIBS and fs-LIBS techniques to detect Cu and Zn in various aluminum alloy samples with different contents. Our results reveal that the spark discharge extends the duration of laser-induced plasma atomic radiation and amplifies the peak intensity of atomic radiation, thereby significantly increasing the time-integrated signal intensity of laser-induced plasma. Under the present experimental conditions, the limits of detection (LoDs) of Cu and Zn in aluminum alloy by fs-LA-SIBS are 16 and 12 ppm, respectively. In contrast, the LoDs of Cu and Zn by fs-LIBS technique under the same laser pulse energy are 96 and 84 ppm, respectively. Hence, for Cu, the LoDs by the fs-LA-SIBS technique are 1/6 of those by the fs-LIBS technique, and for Zn, the LoDs by the fs-LA-SIBS technique are 1/7 of those by the fs-LIBS technique. Our findings demonstrate that the fs-LA-SIBS technique is more sensitive than the fs-LIBS technique in the quantitative analysis of elements and may be a practical approach for elemental analysis in alloys.
Coil-based Wireless Power Transfer for Implanted Pacemakers: A Brief Review
Authors: Hisan Urfa Khairatun , Sabila Liya Yusrina , Amri Muhammad Miftahul
Published: September 2023

Nowadays, implanted permanent pacemakers (PPM) users need to undergo periodic pacemaker replacement surgery. The surgery is needed since the pacemaker's battery is usually depleted in 5-10 years. This surgery, although poses relatively low health risks, is inconvenient for PPM users. Moreover, the surgery can still be dangerous for PPM users, especially considering that most of the users are elderly. PPM replacement surgery is also costly. In addition to the costs of the surgery itself, the PPM users need to bear the price of the new PPM every time they undergo surgery. Currently, when the PPM's battery runs out, the whole PPM needs to be replaced. This is conducted to prevent the possibility of a leak in the battery seal, which might allow the body fluids to enter the PPM. Typically, once a battery is inserted into the PPM, it will be permanently sealed along with all other electronic components, and thus, battery-only replacement is impossible. Thanks to the recent advancement of wireless power transfer (WPT) technology, a PPM replacement surgery might no longer be necessary in the near future. This article presents a brief review of the current state of coil-based WPT technology and its potential applications in pacemakers. Depending on the load and transmission distance, a recent WPT system for PPM could achieve WPT efficiency as high as 97.91% on air and 78% on pig tissue medium. In terms of output power, recent works that we have summarized showed that they are able to transmit power up to 5W on a WPT system implemented on a human phantom. We also discuss the challenges, limitations, and future prospects for WPT in the medical field, particularly for PPM applications.

Huellas de la novela picaresca en el siglo XX: Un estudio sobre Antón Retaco de María Luisa Gefaell
Authors: Núñez de la Fuente Sara
Published: September 2023

Las teorías que recoge este estudio sobre la evolución de la novela picaresca señalan que bajo dicha categoría no se incluye una serie de obras homogénea. Sin embargo, los criterios temporales y geográficos resultan más precisos, pues se trata de uno de los legados más significativos de la tradición literaria española y se encuadra en el Siglo de Oro. No obstante, diversos autores llaman la atención sobre la recurrencia de elementos narrativos picarescos en la literatura de siglos posteriores. Así pues, tras presentar una panorámica sobre la tradición picaresca que expone sus características definitorias en el contexto de sus orígenes, y también su trascendencia en el tiempo y el espacio, se desarrolla un análisis del libro infantil Antón Retaco (1955), de la escritora española María Luisa Gefaell, con el fin de examinar algunas características que evocan la narrativa áurea y cómo se adaptan a un nuevo contexto literario.
A review of the evolution of research on proposals for bamboo culms connections in structural systems
Authors: Gaffuri Bruna A. , Moura Jorge D. M. , Barbosa Juliana C. , de Medeiros Marcelo H. F. , Gobbi Andressa , Silva Ricardo D.
Published: September 2023

Structural systems built from raw bamboo have been used for years due to its highly renewable characteristics, versatility, and abundance in various countries, e.g., China, Indonesia, all over South America, and especially Brazil. It is also considered a low specific weight material, which means it is easy to handle and transport. These characteristics make it a low-cost material for building construction. The objective of this systematic bibliometric review is to identify innovations in bamboo culms structural connections in order to contribute to the advancement of technology applied to civil construction by seeking joints that consider the use of industrialized or standardized products. This review revealed there is still no ideal connection capable of solving the great problem of this subject, which points out the need for more studies on the topic.

Objective: To improve upper extremity recovery in patients with hemiparesis due to stroke using a finger simulator. Material and methods: 50 patients with hemiparesis due to a stroke with muscle strength in the hand - 3 points and degree of spasticity - 1-2 points were selected. Two groups were formed, in the 1st group in the rehabilitation complex a simulator for the fingers of the hand was used, in the control group - not. Results: a simulator for fingers and a set of exercises were developed. Measures were taken to restore hand function to patients of both groups. The effectiveness of using the simulator was proven by tests that showed a greater decrease in spasticity and an increase in muscle strength in patients of the I group. Conclusions: the use of a simulator for the fingers of the hand in the complex to restore the function of the hand in patients with hemiparesis improves the functional capabilities of the hand in comparison with rehabilitation without the use of the simulator.

Rehabilitation of ischemic stroke patients occupies an important place in the structure of rehabilitation due to high prevalence and disability. New modern robotic-assisted methods are increasingly used in such patients. The goal was to evaluate the effectiveness of robotic-assisted rehabilitation methods, using the results of studies presented in Medline, Embase, and the Cochrane research register. After analyzing the results, according to which the new methods are highly effective in improving walking function, balance, reducing swelling of the affected limbs, but it cannot be claimed that they are more effective in improving the motor activity of both upper and lower limbs, more effective pain relief than traditional methods rehabilitation.
Un alma en pena aparece entre los vivos: purgatorio y devoción en la segunda mitad del siglo XIX en Colombia
Authors: Henao Albarracín Ana María
Published: September 2023

Objetivo: proponer un análisis desde la historia cultural de la manera como discursos religiosos de larga tradición –como aquellos sobre la buena muerte, socializadora de las ideas sobre el cielo, el infierno y el purgatorio– adquieren un uso social en un contexto específico. A partir del estudio de las condiciones de posibilidad de tales discursos ante la aparición de un muerto en una parroquia rural, se busca entender la devoción por las almas del purgatorio en el contexto más amplio de la Colombia de la segunda mitad del siglo XIX. Metodología: el análisis se realiza a partir del estudio cualitativo de fuentes primarias, combinando la descripción densa de un espacio micro, relacionado con la dimensión antropológica de una aparición, con la perspectiva macro que permite reconstruir su contexto. Originalidad: este trabajo es un aporte novedoso en el esfuerzo por comprender las condiciones concretas de una aparición, con una mirada reveladora de la manera como opera una creencia y sus posibilidades de emergencia en una red de relaciones que le dan sentido. De esta manera, se llena un vacío en la historiografía del hecho religioso, la cual ha estudiado las creencias religiosas y el destino imaginado de los muertos centrándose especialmente en las prácticas piadosas asociadas a la salvación. Conclusiones: la aparición de un alma en pena permite profundizar en los motivos concretos por los cuales los difuntos permanecen en la órbita afectiva de los vivos, sirviendo para la inculcación de normas y principios cristianos. Además, es reveladora de las preocupaciones sobre el más allá, como expresión de una escatología cristiana que continuaba siendo movilizada por la Iglesia Católica en la segunda mitad del siglo XIX en Colombia. Finalmente, la posibilidad y la forma de comunicarse con los muertos son indicios de una amalgama de prácticas que pueden llegar a contradecir el mismo dogma religioso.
Darío Villamizar Herrera. Crónica de una guerrilla perdida. La historia inédita de la columna del M-19 que desapareció en la selva del Chocó. Bogotá: Debate, 2022. 800 páginas.
Authors: Atehortúa Cruz Adolfo León
Published: September 2023

El libro consta de dos partes. En la primera de ellas, titulada “El preludio de las armas”, Darío retoma, en cierta forma, la historia del M-19 desde su surgimiento, en enero de 1974, hasta las fallidas propuestas de amnistía formuladas por el gobierno de Turbay Ayala. Este periplo resulta absolutamente necesario para quienes vivimos de alguna manera este devenir e intimamos recordarlo, para quienes no lo siguieron al dedillo y requieren aclarar dudas o completar sus horizontes, para nuevos lectores de la realidad nacional y para una población joven que surge recién a la vida política y ciudadana con  la necesidad de conocer este importante trozo de la historia de Colombia y, en particular, el trasegar de la lucha armada revolucionaria, que hace rato conoció su ocaso. La segunda parte del libro describe el escenario al que arribó la guerrilla en el Chocó; la travesía de la columna de la que hacían parte Jorge Iván Rojas, Carmenza Cardona (“La Chiqui”), Édgar Arturo Valencia y Orlando Díaz Otero, participantes en la toma de la Embajada, entre otros; bajo el mando de Hélmer Marín, destacado miembro de la dirección nacional del M-19. Paralelamente, el texto refiere la toma de Mistrató, con sus ventajas y desventajas para la columna que ingresaba y, por último, el desafiante, a veces animado y valiente, pero las más de las veces difícil, desconcertante y desolador itinerario de la que tuvo como nombre “Columna Calarcá” del M-19. En forma consecutiva, el libro de Darío se ocupa igualmente del destino seguido por la columna comandada por Carlos Toledo Plata que penetró al país por Nariño con el propósito de reforzar el Frente Sur del M-19, en donde Jaime Bateman acababa de dirigir la toma de Mocoa. Entre sus consecuencias, señala Darío la ruptura de las relaciones internacionales con Cuba por parte de Colombia y la salida de Gabriel García Márquez del país.

Published: September 2023

Stirred-type fruit yoghurts with two different fruit purees (kiwifruit and banana) were produced and were investigated the physicochemical, volatile compounds, 2,2-diphenylpicrylhydrazyl (DPPH) free radical scavenging activity, cupric ion reducing capability (CUPRAC), total phenolic compounds (TPC), angiotensin-converting enzyme (ACE) inhibitory activity, 5-hydroxymethylfurfural (HMF) content, reducing sugar content and microstructure. The addition of fruit puree affected (p<0.01) total solids, fat, protein, ash, L*, a*, b*, volatile compounds, DPPH, CUPRAC, TPC, ACE inhibitory activity, HMF content, reducing sugar content and overall acceptability whereas it had an insignificant effect on the pH, titratable acidity, apparent viscosity, syneresis (p>0.05). Storage period significantly (p<0.01) affected the titratable acidity, DPPH, CUPRAC, TPC, ACE inhibitory activity, HMF content, reducing sugar content and overall acceptability, as well as the pH, apparent viscosity and a* (p<0.05). Although the addition of banana and kiwi relatively suppressed the characteristic flavour of the experimental yoghurt samples, it improved the DPPH, CUPRAC and TPC. On the other hand, the addition of banana-kiwi was found to increase the content of HMF, the toxic compound. Yoghurt can be recommended as an important source of bioactive compounds with ACE inhibitory activity. According to the microstructure analysis results, a more homogeneous structure was observed in the control group samples compared to the fruit-added yoghurt samples and it was determined that the serum pore diameters were smaller.

Introduction and aim. This study aims to estimate the age of a population in Central India by analyzing the mental foramen using cone beam computed tomography (CBCT). The objectives of the study are to determine the parameters for age determination and study bilateral variations in mental foramen dimensions using CBCT. Material and methods. One hundred and twenty CBCT scans, HD LED monitor, GALAXIS GALLIEOS viewer. Results. Results from the study show significant values for various parameters such as the upper and lower borders of the mandible and mental foramen. Bilateral variations were also observed. The age regression model indicates a significant correlation between estimated and original ages for individuals aged between 31 to 50 years. While the study only analyzed five parameters of the mental foramen, it suggests that a more comprehensive assessment of mental foramen parameters with a larger sample size can yield more definitive results for age determination. Conclusion. As only five parameters of mental foramen had been assessed in this retrospective study, so a comprehensive assessment of various other parameters of mental foramen with an increased sample size may be done for more definitive results for gender and age determination.
