Published: December 2023

En este artículo se describe el estudio que se está llevando a cabo en el Centro de Recursos Educativos de la ONCE en Sevilla con relación al uso del eye tracking para la valoración de la visión funcional de niños con discapacidad visual de 0 a 6 años. Dicho estudio comienza en el curso 2021-2022 y se pretende completar en el 2025. Está, por tanto, en una fase intermedia, y lo que se ofrece en este documento es su descripción y un avance de resultados. La población que participa es muy diversa, tanto con relación al diagnóstico y situación visual como a la presencia y características de otros déficits que se asocian a la discapacidad visual. Desde la experiencia en primeras edades y la obtenida con el uso del eye tracking, destacamos la importancia de cuidar los aspectos externos que favorezcan un entorno de valoración percibido por el niño como seguro y previsible. En este sentido, como en el resto de procedimientos de atención temprana, la participación de la familia sigue siendo un elemento nuclear. Así mismo, consideramos imprescindible dedicar una atención especial al hecho de concretar los parámetros para la calibración y las opciones que ofrece el software del que se dispone. Con esto, se pretende optimizar el acceso a las imágenes realizando una adaptación a las características específicas de percepción de los niños con discapacidad visual. Los resultados iniciales, aun teniendo en cuenta la heterogeneidad de la población, hacen pensar que el eye tracking aporta una información importante para la valoración de toda la población objeto de estudio. Esto es especialmente relevante en el grupo de niños que presentan deficiencia visual cerebral (CVI), acompañada, en muchos casos, de discapacidad motora grave. Finalmente, se considera que el uso de la alta tecnología abre un espacio hacia la intervención que hay que seguir explorando.

The Impact of the Covid-19 Pandemic on the Cross-Sectoral Information Flow in the U.S.
Authors: Čeryová Barbara
Published: December 2023

In the past decades a connection between the financial services and technology sector has evolved into a dynamic and complex relationship. However, they were not spared from the far-reaching effects that the spread of the Covid-19 pandemic brought, each responding in a distinctive manner. This paper examines the alterations in the bidirectional information flow between the financial services and technology sectors provoked by the virus outbreak by employing the concept of transfer entropy. The results document an asymmetric and modest information flow in distribution tails prior to the pandemic, with the technology sector predominating. However, as we move towards central values, the transfer intensity decreases dramatically, even reaching negative values in the flow from the financial services sector. Following the pandemic declaration, while the technology sector maintains its superior position in information transfer, its strength, shape, and symmetry are notably altered, with transmission doubling from the financial services sector, suggesting cross-sectoral contagion in market downturns and instability of the information transfer.

Published: December 2023

La Clasificación Internacional de Funcionamiento, Discapacidad y Salud (CIF) (OMS, 2001) indica que la intervención en salud debe responder de manera apropiada a las necesidades particulares de cada usuario/a. Actualmente, no se cuenta en Chile con pautas uniformes para el diseño de la planificación terapéutica. Esta ausencia de estructura de la intervención fonoaudiológica dificulta la comunicación entre profesionales y obstaculiza una intervención terapéutica adecuada. El objetivo del presente trabajo es proporcionar un marco teórico-conceptual que facilite la planificación terapéutica estructurada de usuarios/as adultos/as con dificultades comunicativas y/o lingüísticas de origen neurológico, considerando estándares internacionales. Se realiza una revisión crítica con una estructura narrativa-conceptual con un muestreo intencionado de las propuestas teóricas actuales. Se propone un conjunto de herramientas teóricas en el marco del modelo de la CIF con el fin de facilitar el trabajo del/la fonoaudiólogo/a.

En este contexto, diversas instituciones de salud, tanto públicas como privadas, han desarrollado sus propios protocolos para el manejo de pacientes adultos con vía aérea artificial. Estos protocolos presentan variaciones en las presiones del cuff utilizadas, lo que puede generar riesgos para los pacientes. Más aun, se ha observado que los profesionales de la salud aplican presiones peligrosas en el manejo de estos pacientes. El objetivo de este estudio fue describir las técnicas y las presiones utilizadas en los protocolos de instituciones hospitalarias de salud pública en Chile para el manejo de la presión del cuff en pacientes adultos con vía aérea artificial. Para ello, se llevó a cabo una revisión de protocolos vigentes de estas instituciones. Los resultados muestran que la mayoría de los protocolos mencionan el uso de una técnica objetiva, aunque no especifican necesariamente el instrumento a utilizar. La presión mínima promedio en los protocolos revisados es de 28,44 cmH2O, mientras que la presión máxima promedio es de 36,12 cmH2O. Solo el 23,80% de los protocolos cumplen con los valores recomendados actualizados. En conclusión, la mayoría de los protocolos mencionados utilizan una técnica objetiva. De ellos, el 68,75% sugieren presiones del cuff por sobre los valores seguros, lo que podría afectar la atención de los pacientes durante su hospitalización.

Los resultados mostraron una asociación entre el nivel de ideación suicida, el bullying (rs 0,73; p<0,05) y algunas dimensiones de la competencia social: reevaluación cognitiva (rs-0,44; p<0,05), ajuste normativo (rs-0,659; p<0,05) y eficacia social (rs -0,45; p<0,05). Se concluye que existe una correlación entre bullying y nivel de ideación suicida. Además, se observa que algunas dimensiones de la competencia social están asociadas a la ideación suicida en la población de adolescentes con TEA.
Escribir y enseñar el pasado para transformar el presente: la influencia marxista en la reflexión sobre el sentido de la historia en los “largos sesenta” en Chile
Authors: Ortiz Figueroa Matías
Published: December 2023

Este articulo analiza la influencia marxista en la historiografía y en las propuestas de enseñanza de la historia escolar en los años sesenta en Chile. Específicamente se abordará el sentido que se le otorgó a la elaboración de investigaciones históricas y su enseñanza entre historiadores, docentes y estudiantes de Historia. De ese modo, más allá de las cuestiones referidas a métodos y derivas conceptuales, interesa captar la función que desde esta tribuna ideológica se le otorgó a la disciplina histórica en la sociedad, relevando el sentido político, social y democratizador que el estudio del pasado llevaba consigo de manera inmanente. Se propone que, a diferencia de la historia conservadora y las formas de enseñar que desde aquí se erigen, las analizadas tuvieron al presente histórico, las coyunturas políticas y las desigualdades como principal lugar de interrogación, redefiniendo la utilidad del estudio del pasado desde una perspectiva ética y política, con proyección socialista y latinoamericana e interrumpiendo el tiempo histórico lineal y de progreso que caracterizó a la historia “tradicional”.

Survey on rice false smut disease has been conducted at Erode, Tanjore, Perambalur and Coimbatore districts of Tamil Nadu, India. Among the areas surveyed, higher disease incidence was recorded in the paddy variety bhavani cultivated in Bhavanisagar, Erode district in which the rice false smut disease incidence was recorded as 40%. The pathogenicity test revealed the symptom development within 12-15 days of conidial suspension injection. In order to characterize the fungal isolates of Ustilaginoidea virens, a causal for rice false smut disease was cultured on Potato Sucrose Agar (PSA) medium. The pathogen was characterized morphologically which exhibits white mycelium that turns yellow and becomes olive green on maturity. Molecular confirmation was carried out among the collected isolates that were amplified at 380 bp region which is found specific for the pathogen Ustilaginoidea virens using the primers US 1-5 and US 3-3. The extraction and purification of ustiloxin was carried out using flash chromatography. On purification 100% water and 30% ethanol fraction was collected separately. The cytotoxicity assay of ustiloxin in brine shrimp resulted that the mortality at 1% concentration of ustiloxin was 96% and the lowest mortality (26%) was observed at 0.2% concentration. The lethal dosage 50(LD50) was confirmed at the concentration of 0.4% ustiloxin having the mortality rate of 52% using brine shrimp bioassay
MICROBIAL-ASSISTED SOLID WASTE MANAGEMENT-A CIRCULAR ECONOMY APPROACH

The soil contains a significant quantity of microbial life, including a vast range of bacteria, archaea, yeast, fungi, algae, and protozoa. They can thrive in harsh environments like hot springs, deep beneath rocks, and in subfreezing temperatures. However, although these biological communities are considered significant in sustaining a sustainable biosphere, roughly about 90 % of microorganisms significance remains unknown. The majority of the microorganisms that are often found in solid waste are bacteria and fungi. These species are collectively referred to as Solid Waste Microflora. They grow using the elements from the waste as their food. Municipal solid waste should be maintained in a satisfactory state before discharge to decrease biological activity, prevent or postpone the release of toxic substances into the environment, and decrease odor generation. Organic waste composting represents a bio-oxidation sequence, encompassing the mineralization and partial transformation of organic substances. This sequence results in an endproduct devoid of pathogens and phytotoxicity, while also inheriting certain humic characteristics. The local microbial population actively mediates the biodegradation and conversion process during composting. Identification of these microorganisms is necessary as they keep the flow of nutrients from one system to another. Composting also aids in waste disposal to a larger level and serves as an organic source of nutrients. To attain the objectives of sustainable waste management, waste generation must be minimized, waste materials must be recovered and recycled, and energy must always be recovered to preserve resources for the future. Recovering energy from abandoned waste has the potential to generate energy for communities, produce energy in industries, and reduce greenhouse gas emissions (GHG) and other toxic air pollutants

After assessing the current status of the working environment and workers’ health of the enterprise, the authors have advised enterprises to apply a number of solutions to improve working conditions such as establishing an occupational safety and health (OSH) management system; designing anti-heat ventilation system by exhaust fan system creating negative pressure in the workshop and cooling by Cooling Pad andre-organizing the lighting system. After more than a year of implementing these solutions, when re-evaluating, they all give positive results: reducing the temperature by 3-5.50 C, dust concentration from 0.15-0.45 mg/m3 , increasing light intensity levels to 150-280 lux. As a result, the company’s revenue also increased.
Amenorrhea and Stress Fractures in Female New Jersey Division III Collegiate Runners: An Opportunity for Increased Health Education
Authors: Forester Emily , Pellegrino Tara
Published: December 2023

BACKGROUND: In the National Collegiate Athletic Association (NCAA), 9.1% of the injuries reported by women’s cross-country athletes between 2014-2019 were fractures. Both history of amenorrhea and prior stress fractures have been found to predict incidence of subsequent bone stress injuries among female athletes. Although excessive exercise is a major contributor to the development of amenorrhea, there are currently no studies on the association between amenorrhea and stress fractures in New Jersey (NJ) National NCAA Division III Women’s cross country or track athletes. This study aims to determine if there is an association between incidence of amenorrhea and subsequent occurrence of stress fractures among this population, and to identify a possible area for increased reproductive health education.
METHODS: This is a survey-based study. Participants were female athletes over the age of 18 who currently participate in collegiate cross country or track running at a NJ Division III school. Coaches of the Division III cross country and track teams in NJ distributed a survey to their female athletes to gain participants for this study. Survey data included information on participant menstrual history, stress fracture history, and athletic involvement. Participants also indicated if their school’s staff had ever educated them on the importance of menstrual regularity and athletics. Descriptive statistics and comparison between groups were analyzed.
RESULTS: In total, 68 survey responses were collected. Survey respondents included female NJ cross country and track athletes ages 18-23, from a total of eight institutions. During training or competition, 58.8% of the study participants missed at least one menstrual cycle and 45.6% experienced a stress fracture. There is a significant association between having missed at least one menstrual cycle during training or competition and the number of stress fractures experienced by the athlete (p = 0.044). Only 30.9% of respondents indicated that someone from their school’s staff spoke to them about the importance of maintaining regular menstruation during training.
CONCLUSION: This study confirms that both amenorrhea and stress fractures are commonly seen among NJ NCAA Division III female cross country and track athletes. Our data also highlights a need for increased education of NJ Division III female athletes regarding the importance of maintaining regular menstruation as a means of stress fracture prevention. Further investigation of the role of amenorrhea on the incidence of stress fractures may shine light on an important area for prevention and increased health education.
