Authors: NOUZRI Omar , Ejjami Rachid
Published: November 2024

This integrative literature review (ILR) explores the transformative potential of artificial intelligence (AI) in optimizing in-store logistics, a crucial aspect for retail environments striving to meet growing consumer demands for convenience and quick product availability. It aims to provide retail managers and logistics specialists with actionable insights on AI-driven tools that enhance competitiveness by improving inventory management and space utilization in retail settings. The conceptual framework is framed by functional schema design, user acceptance and experience, operational efficiency, data security and privacy, and equitable access, emphasizing the ethical and inclusive implementation of technology. Key findings suggest that AI improves demand accuracy, reduces inventory mismatches, and enables adaptable store layouts that respond dynamically to real-time consumer behavior, creating a more efficient, responsive, and customer-centered retail environment. Additionally, this study examines the adoption of AI in cashier systems as a response to evolving consumer expectations for efficient digital shopping experiences, revealing that AI-enabled cashier systems significantly reduce wait times and operational costs while providing personalized experiences through real-time analytics. However, challenges such as robust data security protocols, inclusive design for diverse user groups, and employee reskilling remain critical as automation progresses. Recommendations focus on privacy-enhancing data practices, user-friendly interfaces, and hybrid solutions combining human support with automation to foster inclusivity and consumer trust. Future research should address the long-term impacts of AI in retail, cultural adaptability, customer engagement, and secure data handling to support a balanced, customer-centered approach to automation in the retail sector.
Mathematical Models for Predicting Network Traffic in Cloud Computing Environments
Authors: Liu Xingyu
Published: November 2024

Effective network traffic prediction is crucial for optimizing resource allocation and ensuring efficient performance in cloud computing environments. In this research, mathematical models are developed to use historical data, factors, and other data to predict future network traffic patterns more effectively. In this context, we then compare an array of time series models such as ARIMA, LSTM, as well as the Prophet model so that we can determine the cloud environments most appropriate for each. These models include time and day of the week as well as the general activities of the users in the network in order to mimic the real flow of network traffics. The experimental results concern the efficiency of the proposed models as opposed to existing approaches and give a lot of information to network administrators and cloud service providers. The outcomes make a significant contribution as to the formulation of intelligent approaches in resource management and improve the dependability and performance of cloud computing environments.
Security and Privacy Analysis on Personal Identifiable Informationfor Connected Commercial Vehicles
Authors: Carlton Jason
Published: November 2024

With many Americans eager to resume travel after prolonged restrictions from the coronavirus pandemic, car rentals are on the rise. According to Auto Rental News, “2021 U.S. Car Rental Revenue Climbs 21% Year-Over-Year” (Brown, 2021). In conjunction with increased car rental, and associated travel, we can expect to see an increase in cyber security and data privacy attacks. In the digital age, enterprises have a responsibility to protect consumers’ Personally Identifiable Information (PII). As it pertains to rental vehicles, when consumers connect their mobile devices to a rental vehicle’s Entertainment and Infotainment System or utilize the built-in navigation feature, they do so, unbeknownst to themselves that the information from their devices is transferring to the vehicle, where it will remain, unless properly expunged from the system. A large majority of consumers are blissfully unaware that their PII is being stored, and how easy it would be for an adversary to potentially breach their data security and privacy. To expand upon this hypothesis, I conducted a further investigation on the subject, by partaking in the rental of three different vehicles, each belonging to a different manufacturer (Nissan, Chrysler, and Maserati), from three different vehicle rental companies (Enterprise, Hertz and Turo). I then, as a consumer, tested my hypothesis to determine if, I was able to easily breach the prior consumers’ data security and privacy by viewing devices that had previously connected to the vehicle, as well as any of the previous consumers’ personal information. The results were undeniable; the PII of the previous consumers is not protected.

Published: November 2024

This report summarizes the findings of a deep retrofitting modelling study of four government buildings across the UAE. Buildings envelope assessment, HVAC, and electrical systems design, installed conditions, maintenance practices and operation methods, and rigorous engineering analysis has been performed for the four buildings to produce calibrated energy models that confirm a good correlation between actual annual energy consumption and advanced simulated energy modeling results. IES-VE software, ASHRAE Guideline 14, and IPMVP were the basis of the energy model calibration based on actual data. Energy retrofitting options were applied to the calibrated energy models of the four government buildings where advanced computational modeling studies have been utilized to analyze different thermal envelope components and external fabric energy efficiency measures in conjunction with the actual HVAC systems. The results have shown that it may be financially challenging to implement a single envelope retrofitting measure on any of the four buildings due to high payback periods. Nevertheless, when conducting an optimization through a holistic building approach targeting the overall envelope enhancements, the financial modeling results provide significantly improved and provide reduced payback periods of the solutions, making them more attractive to investors. Based on the energy modeling results and the cost of the various proposed building envelope solutions provided by Saint-Gobain, the payback period in all cases varies between 15 to 20 years. However, huge savings in terms of carbon emissions are achieved by implementing the deep retrofitting measures, crucial to achieving carbon neutrality within the UAE built environment. Deep retrofitting is a promising segment of the execution roadmap as part of the UAE's decarbonization journey; even though it is capital-intensive upfront, it has a major impact on long-term operational savings. Moreover, it is often more cost-effective than building new and energy-efficient structures from scratch. The findings indicate that deep retrofitting can be a techno-financially viable solution if it is well-planned during major refurbishment or as part of building maintenance. It has significant potential to reduce carbon emissions while also providing a range of benefits such as operational cost savings, improved thermal comfort a feature which has a direct impact on perceived efficiency and productivity at work, indoor air quality, improved asset value, reputational enhancement, and better choice for environmentally-cautious tenants or buyers.

EFFECTIVENESS OF NUTRITIONAL INTELLIGENCE PROGRAM TOWARDS IMPROVING MATERNAL KNOWLEDGE AS AN EFFORT TO PREVENT STUNTING IN CHILDREN
Authors: Irhamna Aulia Irhamna , Razak Alifah Indalika Mulyadi
Published: November 2024

Nutrition is an important source of energy for children to be able to absorb learning information. Various studies have shown that good eating habits, nutritional balance of composition, and physical activity can support children's development. In line with the results of the study, there needs to be a sustainable learning pattern so that the child can easily understand about nutrition, namely parents as the nearest environment of the child as an effort to prevent stunting cases in the child. The participants of this study were 30 mothers in Bojongsoang District, Bandung Regency, West Java Province.  This research aims to test the effectiveness of nutritional intelligence programs in mothers as stunting efforts in children through the design of the-before-after study design experiment with two experimental and control research groups. Specifically packaged in the form of training activities that include materials: (1) cooking; (2) healthy eating; (3) fitness; and (4) fun. In general, the average maternal knowledge score of nutritional intelligence and stunting in the experiment group (Mpre test = 97.5 and Mpost test =123.7) both pre-test and post-test had higher scores than the control group (Mpre test = 97.3 and Mpost test= 88.5). By comparison, the control group's pre-test and post-test scores decreased by 4.7%, while the experiment group saw an 11.8% increase in scores. The effectiveness of the learning model can be measured through Mann Whitney tests that compare the average pre and post test scores measured through stunting instruments, which are demonstrated through the significance of scores in the control group and experiments after being given nutritional intelligence programs. This means that nutritional intelligence programs are considered effective in increasing maternal knowledge as an effort to prevent stunting in children.

Published: November 2024

The government has issued a policy requiring that Early Childhood Education Institutions must be conducted in a holistic-integrative manner to improve the quality of Early Childhood Education, provide a comprehensive, quality service, and involve all related education stakeholders.  As a matter of fact, that the partnership between school, family, and community could enhance student's learning, accommodate the diverse needs of the student and bring an inclusive culture in education, it's essential for the teacher to develop communication partnership plan. This study was conducted in a systematic review with a qualitative approach. The communication values that can be implemented to develop an effective partnership are include understanding and respecting, openness, mutual trust, and commitment. The possible obstacles to implement this communication partnership plan components include a judgmental attitude when working with family and community, school as a hostile environment, the assumption that family and community are less able in the educational process, and lack of teacher partnership training.
Preference of Early Childhood Teachers in Using Instructional Media: A Systematic Survey
Authors: Thaariq Zahid Zufar At , Khoirunnisa'
Published: November 2024

Instructional media is a fundamental need for teachers, especially those who teach early childhood, in transmitting messages as taught material. Early childhood teachers have certain preferences when developing (by design) or utilizing instructional media, especially in the realm of digitalization. These preferences are tailored to the learning needs of early childhood. This study aims to find the preferences of early childhood teachers in utilizing or developing instructional media. This quantitative research uses a systematic survey (percentage) approach involving 30 early childhood teachers as respondents. The results showed that there was a dominant preference of early childhood teachers in optimizing instructional media. These preferences include LCD Projectors, traditional whiteboards, wall magazines, Microsoft Word, self-drawing, smartphone cameras, voice recordings, WhatsApp Call, public television, YouTube live broadcasts, Zoom, Capcut, Google, WhatsApp, Google Form and Google Classroom. This means that early childhood teachers' understanding of instructional media is good, but needs to be strengthened in their digitization capabilities. Thus, this research can be used as an alternative reference in empowering early childhood teachers in the future.

Authors: Aisah Siti , Aprilia Granasti
Published: November 2024

Apart from food, sanitation and access to health services, warmth and responsiveness by adult caregivers to a child’s needs are equally important for optimal survival and development. This research was carried out to examine the effect of a responsive parenting program towards early childhood development in 17 ChildFund-assisted locations in Indonesia. A comparative research design was used to compare results of responsive parenting implemented in both intervention and non-intervention groups. Quantitative data were collected out of interviews and assessments with parents and children, examining parenting knowledge, attitude, and practices among a total of 321 parents who participated in the program and 358 non-intervention parents. The development of a total of 311 children of the intervention group and 344 children of the non-intervention group were also measured. The main outcome of early childhood development towards 0 to 35-month-old children is measured through CREDI (Caregiver Reported Early Childhood Development Instrument) and IDELA (The International Development and Early Learning Assessment) for children aged 42 to 72-month-old. Changes in parenting behavior were measured using HOME (Home Observation for Measurement of the Environment) to disclose parental responsiveness and Multiple Indicator Cluster Survey (MICS) version 6 to observe the application of stimulation activities and parental discipline practices towards children.

Crisis reflexivity: the fragile regime of citizenship in Greece’s compounded crises
Authors: Koulaxi Afroditi
Published: November 2024

The paper explores how the crisis imaginary shapes citizen identity in relation to the migrant noncitizen as well as the media’s role in enhancing or containing the crisis. The communicative process of crisis reflexivity offers a conceptual tool to understand the consequences of limited or absent encounters with noncitizen Others for the citizens’ construction of identity. Within the spatio-temporality of compounded crises in an Athenian neighbourhood, the study’s multi-method approach combines 30 in-depth interviews with Greek citizens with offline and online participant observation. The empirical findings reveal that embodied encounters shape the perception of citizens as victims in light of structural inequalities and the existential uncertainty tied to media disinformation and fear. However, for those with progressive views, predominantly mediated encounters can open up an avenue for a politics of justice and generate feelings of cosmopolitanism towards citizens-in-the-making.
Slippery discourses of intertwined crises
Authors: Minga Ester
Published: November 2024

The outbreak of a pandemic inevitably links with migration as containment measures usually involve the closure of borders. In the Portuguese context, mediated discourses of these intertwined crises were varied and multifaceted, reflecting the country’s postcolonial peculiarity as both a provider of emigrants and host country to distinct fluxes of migrants. Through a qualitative analysis of selected items published in Portuguese newspapers Expresso, Diário de Notícias, and Correio da Manhã, I will show how similar issues involving Portuguese emigrants and distinct groups of migrants have been differently framed in news items related to the Covid-19 pandemic. The aim is to discuss how this unstable coverage speaks to, and collides with, the deep social imaginary of Portuguese emigration and the widespread idea of a Lusophone space characterized by the harmonious conviviality of different people. I argue that the fragmented frames represent a symptom of crisis themselves, revealing unsettled discourses and alternating anxieties.
Podcasting mundane practices of solidarity and resistance in post-migrant Sweden
Authors: Gustafsson Jessica
Published: November 2024

Sweden is a post-migrant society where the suburbs of the largest cities in Sweden have become the symbol of failed integration in public debate and media. To broaden the representation, young people from the suburbs use podcasting to challenge and present their own perspectives. Based on content analysis and interviews with selected podcasters this article explores how they position themselves in relation to mainstream media and society by focusing on their distinct media practices. The study suggests that these podcasts can be perceived as sites of cultural production where the articulation of mundane practices of solidarity and resistances are central. It is illustrated in the content and the guests they invite; and reflected in how the podcasters articulate their aims and goals, as well as how they position themselves in relation to other actors and spheres.
Media engagement during Russia’s war against Ukraine
Authors: Vihalemm Triin , Vunš Marta
Published: November 2024

The contribution explores the contested relationship with media among young Russian-speaking Estonians from migrant family backgrounds since Russia’s invasion of Ukraine. Our analysis sheds light on how the war context, characterized by the securitization of Russian state-controlled media usage and ideological tensions within the Estonian Russian-speaking community, impacts the media-related perceptions and practices of young Russian-speaking Estonians. We also investigate media professionals’ views on building relationships with their audience. Our investigation reveals an existing gap in connectivity between Estonian local Russian-language media outlets and their young audience. This gap is rooted in the production logic of these media platforms, which has previously hindered effective engagement. The context of Russia’s war against Ukraine exacerbates this disconnect. Improving the currently poor professional practices of audience engagement, particularly production-oriented approaches, would enhance connectivity and the epistemic power of Estonian Russian-language media and motivate young Russian-speaking Estonians to use it as a vehicle for their social agency.

The seed quality of Deutzia Thunb. in the conditions of the Bashkir Urals
Authors: Murzabulatova Fanuza Kavievna , Polyakova Natal'ya Viktorovna
Published: November 2024

Representatives of the genus Deutzia are widely used in decorative gardening in European countries. In regions with a more severe climate, the plants are less viable. Probably for this reason, this crop is poorly studied and practically not used in landscaping in northern latitudes. However, a small group of species of the genus Deutzia has broad adaptive properties when grown in new climatic conditions. Therefore, at the moment there is a need to assess the quality of seeds of some types of action in the conditions of the Southern Urals. The aim of the work is to identify the characteristics of the quality of seeds of resistant species of the genus Deutzia for cultivation in the Southern Urals. The material for the study was the seeds of 3 species of deuterium cultivated in the South Ural Botanical Garden-Institute of the UFIC RAS and most adapted to the climate of the area of introduction: D. parviflora Bge., D. parviflora var. amurensis Rgl., D. glabrata Kom. The seasonal rhythm of plant development was studied according to the generally accepted method of phenological observations; winter hardiness was determined on a 7-point scale of the Main Botanical Garden of the Russian Academy of Sciences; seed weight was determined by weighing: the result was the average weight of 3 canopies of 1000 pieces; seed germination and germination energy were determined according to GOST. The seeds of the studied species of deuterium are approximately the same and average 0.03 g, but the seed weight of D. parviflora var. amurensis is slightly lower compared to the other two species. Laboratory and soil germination in D. parviflora has maximum parameters (about 67%), also in this species the maximum germination energy is noted (31%), the minimum values of this indicator are recorded in Deutzia glabrata (15%). The laboratory germination of seeds after 1 year of storage remains relatively high, but after 2 years of storage it decreases sharply, and after 3 years the seeds no longer germinate. Thus, the studied types of actions are promising for introduction into culture and wide application in landscaping of settlements of the Republic of Bashkortostan.
Language Issues in Ukrainian Sports Media during the Wartime
Authors: Horiguchi Daiki
Published: November 2024

This article analyses language issues concerning Ukrainian and Russian in Ukrainian sports media during the wartime in terms of language ideologies. It examines language-related comments of 103 Ukrainian sports figures, including retired athletes, coaches and officials from 21 disciplines. The analysed dataset consists of 127 textual and 31 video units comprising the comments from Ukrainian sports media and athletes’ social media platforms. In Ukrainian sports, traditionally associated with Russian as the dominant language, the prominent language-related issue today is the shift from Russian to Ukrainian, triggered by Russia’s full-scale invasion of Ukraine, as is generally observed in wartime Ukraine. Since 2022, at least 31 sports figures publicly announced their language shift. Although language is not inherently linked to sport itself in athletes’ discourse, today, language issues are becoming increasingly entangled with war-related topics. Athletes’ discourse regarding their language shift reveals patterns: they embrace Ukrainian, explain their linguistic and geographic backgrounds, and distance themselves from Russian. Interviewers highlight athletes’ language choice and practice by appraising their Ukrainian and appreciating their effort to speak the language. Overall, athletes’ comments reinforce the language ideology “Language matters”.
El encuentro del cementerio con la ciudad: interfaces y potencialidades
Authors:   , Braukmann Manzur María José
Published: November 2024

Esta investigación estudia los cementerios y su relación con la ciudad, focalizándose en los escenarios programáticos que las distintas tipologías de borde proponen y su impacto en la relación con sus entornos. Y la llegada del cementerio parque que modifica la noción de límite con respecto a la urbe, con cerramientos menos opacos que intentan promover una conexión más estrecha, al menos en lo visual, con el entorno urbano. Sin embargo, surge la interrogante de si este modelo propone realmente una integración con la ciudad mediante sus lógicas internas de tipología parque, o más bien continúan esta lógica interna del cementerio urbano tradicional. Entendiendo que el cementerio tradicional definía un borde claro con muros nicho, sistemas adosados, pórticos, plazas y ejes de acceso procesional. Este estudio asume un carácter exploratorio y, para ello, el levantamiento de casos de cementerios urbanos nacionales e internacionales mediante fotografías, planos y principalmente perfiles, se proponen como un método de investigación. Se busca entregar información sobre sus dimensiones y su relación con la ciudad, principalmente mediante la lectura de sus bordes y las situaciones urbanas que se dan en ellos. Considerando que estos, en la cultura latinoamericana, tienden a estar resguardados y no son de libre paso, a diferencia de la mayoría de ellos en la cultura anglosajona, donde es posible circular libremente. La investigación espera evidenciar cómo estas configuraciones de borde no solo influyen en la percepción de seguridad y el uso de los espacios adyacentes, sino también en cómo los cementerios pueden ser re imaginados como espacios de encuentro y pertenencia dentro de la trama urbana, potenciando el rol de su cara ciega, como componentes activos del paisaje urbano contemporáneo. A través de este análisis, se propone contribuir a un entendimiento más profundo de la relación entre los cementerios y la dinámica urbana, ofreciendo una variedad de material gráfico que permita impulsar propuestas de reconciliación entre estos espacios y su entorno inmediato.
Ciudad sobre ciudad: azoteas y cubiertas como nuevos suelos urbanos
Authors:   , Ibacache Moraga Felipe
Published: November 2024

La (re)densificación del centro de Santiago, conocido a lo largo de décadas por su carácter institucional, comercial y de valorización patrimonial, implica una readaptación de su medio construido y redefinición programática, a medida que el carácter de vecindario y la vida a escala de barrio es incorporada como una capa más; espacios públicos de alto valor que se presenten como contenedores de esta vida urbana residencial, la incorporación de una gama de equipamiento relacionado a dinámicas de habitar doméstico y lugares que permitan establecer relaciones más virtuosas con el contexto se presentan hoy como los principales desafíos a enfrentar por medio de la planificación urbana y la arquitectura. Sin embargo, ¿qué ocurre cuando esta readaptación del medio construido queda condicionada por una muy baja disponibilidad de suelo urbano sobre el que poder planificar este centro residencial en desarrollo?, ¿Es posible fundar nuevo suelo en contextos en donde el porcentaje de área construida es casi total? Ante este panorama, aparentemente desalentador, surgen algunas ideas que describen posibles caminos para la creación de nuevo suelo, aunque lo que se propone en esta investigación es dejar de mirar el “nivel calle” como la opción más viable, levantando la mirada un poco hacia la coronación de los edificios, allí donde, así como nuestra visión, la planificación no llega muy a menudo. Así, el presente trabajo profundizará sobre las posibilidades que otorgan las azoteas y cubiertas de los edificios consolidados del centro histórico de Santiago para articular nuevos suelos públicos y colectivos que, a través de la práctica de arquitectura a escala urbana y bajo la premisa de “construir sobre lo ya construido”, funcionen como el soporte a esa nueva vida urbana residencial que tanto requiere hoy este sector de la ciudad.
Paisaje cultural marítimo: de la productividad al servicio ecosistémico marino en el fiordo Comau
Authors:   , Venegas Ramírez Daniel
Published: November 2024

Chile, país de mar que cuenta con una costa de 6.435 kilómetros de extensión. Sin embargo, este mar ha sido constantemente invisibilizado al momento de relatar la geografía nacional que resalta sus atributos en los valles cordilleranos de los Andes donde habita la mayor parte de la población.En la Patagonia norte del país, al extremo oriente del golfo de Ancud se encuentra el fiordo Comau, lugar donde el paisaje cultural marítimo se presenta como un ámbito con múltiples infraestructuras que permiten la conquista del mar, articulando las actividades productivas -desplazamientos, pesca, cultivos y/o extracción- que posibilitan el habitar en territorios australes. El mar es un paisaje que conecta y entrega recursos de los que depende la subsistencia de los pobladores.Estos artefactos al servicio del habitar, de la conectividad y la productividad, en las últimas décadas, debido al incremento de la pesca industrial y principalmente al cultivo acuícola de la salmonicultura, han degradado la biodiversidad marina e irrumpen en los procesos cíclicos del ecosistema de áreas costeras.Se evidencia así un momento crítico para investigar los fenómenos en torno al sistema hídrico, sus dinámicas, procesos ecosistémicos y prácticas productivas, que permite identificar cómo atender a las necesidades sociales y ecosistémicas de un paisaje en transición.Se busca que la comprensión del territorio; sus procesos hídricos y ecosistémicos, sus dinámicas sociales, los artefactos y técnicas marítimas que se han desarrollado históricamente permitan redefinir las infraestructuras de bordemar que permitan desarrollar una interfaz entre mar y tierra en la apartada localidad de Vodudahue. Para de esta manera, obtener estrategias proyectuales desde la conectividad y la productividad de cultivos acuícolas multitróficos, que establezcan el bordemar como el sitio desde donde impulsar la recuperación del ecosistema marino deteriorado por prácticas productivas indiscriminadas de la industria salmonera.En las principales problemáticas que aborda la investigación se encuentran, primero, la recuperación ecosistémica marina y luego, la conectividad marítima del estuario de Vodudahue con los desplazamientos de embarcaciones del fiordo Comau. La implementación de un proyecto de arquitectura del paisaje, como una interfaz que establezca relaciones ecosistémicas y sociales, posibilita atender ambos enunciados desde las infraestructuras que construyen el paisaje cultural marítimo. Dispositivos que puedan, además de funcionar para la conectividad y la productividad, presten servicios ecosistémicos para el mar interior de Chiloé.

Asociación entre el uso de audífonos y los niveles de actividad física en adultos mayores con hipoacusia: análisis conjunto de las Encuesta Nacionales de Salud (ENS) de Chile 2009-2010 Y 2016-2017
Authors:   , Ramos Rojas José Tomás
Published: November 2024

El envejecimiento poblacional ha aumentado los problemas de salud en los adultos mayores (AM), resaltando la importancia del envejecimiento activo para un envejecimiento saludable. Sin embargo, los AM frecuentemente no cumplen con las recomendaciones mínimas de actividad física (AF). La hipoacusia, una limitación sensorial común en los AM, se asocia a niveles reducidos de AF. Los audífonos son una opción terapéutica que podría mejorar la AF, aunque la evidencia es limitada y los resultados no son concluyentes. Este estudio transversal utilizó datos combinados de las Encuestas Nacionales de Salud (ENS) de Chile 2009-2010 y 2016-2017, enfocándose en AM con indicación médica de audífonos, sin discapacidades cognitivas o motoras. La AF se categorizó según el cuestionario GPAQ, y se incluyeron variables como frecuencia de uso de audífonos y factores sociodemográficos. Los modelos de regresión ordinal ajustados mostraron que el uso ocasional, raro o nulo de audífonos se asoció significativamente con menores probabilidades de tener un nivel alto de AF (OR entre 0,13 y 0,16; p<0,05). En una muestra expandida de 599.912 (356 observaciones no expandidas), el uso de audífonos mostró una asociación positiva con mayores niveles de AF, independientemente de la edad, nivel socioeconómico y comorbilidades, destacando su potencial para promover el envejecimiento activo.
La conciencia ambiental como proceso psicológico superior. Estudio con estudiantes de establecimientos educacionales públicos del sur de Chile
Authors:   , Prosser Bravo Gabriel Ignacio
Published: November 2024

Este estudio aborda la conciencia ambiental desde una perspectiva sociocultural, integrando teorías neopiagetanas y vygotskianas. Se centra en cómo los estudiantes de sexto a octavo básico en colegios públicos chilenos desarrollan su conciencia ambiental a través de un juego de mesa diseñado específicamente para este fin. El juego fue probado con 54 estudiantes y sus docentes en dos sesiones grabadas y analizadas en detalle. Los análisis revelan que cuatro elementos del juego (el tablero, las cartas-problema, el termómetro y las cartas-solución) promovieron el desarrollo de la conciencia ambiental en los estudiantes. Se observaron distintos niveles de conciencia ambiental: sincretismo, atomismo ambiental, tecnocentrismo, ética del cuidado y ecocentrismo. El estudio destaca el impacto de trabajar con problemas locales complejos y las emociones intensas generadas durante el juego. Aunque los resultados muestran una transformación en la manera de entender lo ambiental, se subraya la necesidad de más investigaciones para validar estos hallazgos en otros contextos y grupos etarios. Además, se reconoce el valor del dispositivo metodológico para futuros estudios sobre la conciencia ambiental desde esta perspectiva teórica.

Introduction: Choledochal cysts in adults are rare, as most are diagnosed in childhood. The concern for malignancy in adults adds to the expenses associated with evaluation and management. A aetiology can be congenital or acquired. Acquired biliary wall thinning, caused by the reflux of pancreatic juice, can be a contributing factor in adults. Long-term follow- up after surgery is essential to optimise the treatment. However, not many studies have documented the long-term outcomes of surgery. Aim: To study the short- and long-term outcomes of patients undergoing surgery for adult choledochal cysts {choledochal cyst excision and Hepaticojejunostomy (HJ)}. Materials and Methods: This was a retrospective cohort study of patients aged 18 years and older with choledochal cysts who were diagnosed and operated on between 2012 and 2022 in the Department of Surgical Gastroenterology, Bangalore Medical College and Research Institute (BMCRI), Bengaluru, Karnataka, India. Patients were diagnosed using imaging and subjected to open choledochal cyst excision and HJ. Outcomes like morbidity and mortality associated with the procedure, both in the short- term and long-term, were studied. Continuous variables like age were represented as mean±standard deviation, while categorical variables (such as CBD diameter) were represented as percentages/proportions. Statistical Package for the Social Sciences (SPSS) (version 25.0) was used for statistical analyses. Results: A total of 128 patients were included in the study, with a mean age of 48.92±16.20 years. Type I cysts were seen in 61.72% of the cases, while Type IV A constituted 38.28%. The mean diameter of the Common Bile Duct (CBD) in the study sample was 23.13±14.88 mm, with fusiform dilatation. Endoscopic Retrograde Cholangiopancreatography (ERCP) with stenting/stone clearance was performed in 41 patients. Short-term complications occurred in 48 (37.5%) patients, with Surgical Site Infection (SSI) being the most common early complication. Early postoperative mortality was observed in one patient (0.78%), On long-term follow-up of 83 patients, mortality occurred in six patients. A total of 18 patients complained of abdominal pain during long-term follow-up. Conclusion: Choledochal cyst still remains a significant surgical disease in the adult population, especially in a tertiary care centre. Timely surgical intervention is essential to prevent the short- and long-term complications associated with this condition.

Introduction: Urolithiasis is the formation of stony concretions in the bladder or urinary tract. Nearly 10% of the population suffers from urolithiasis, which has a high chance of recurring. Many resources are used to treat urinary stones globally, but the need for prevention has been neglected. Aim: To determine the levels of Calcium (Ca), Phosphorus (P), Uric Acid (UA) and Magnesium (Mg) in the blood and urine of patients with urolithiasis, as well as in urinary stones post-procedure. Materials and Methods: This cross-sectional study was conducted at the Department of General Surgery at the Himalayan Institute of Medical Sciences (HIMS), Swami Ram Nagar, Dehradun, Uttarakhand, India, from November 2021 to October 2022. A total of 80 patients suffering from urolithiasis were involved in the study. Serum and 24-hour urinary samples were collected for quantitative analysis of Mg, Ca, UA and Phosphate (Ph) levels. Urinary stones postsurgery were sent to the biochemistry section of the reference laboratory for semi- quantitative colorimetric determination and morphological analysis. Spearman’s Rank correlation coefficient was used to correlate two quantitative variables and a p-value of <0.05 was considered statistically significant. Results: In the study, 77.5% of the patients were males and 22.5% were females. Based on their fundamental components, a single calcium oxalate calculus was found in 39 patients. The levels of biochemical parameters associated with urinary stones were as follows: Ca component= 38.13±5.53 mg/dL; Mg component= 10.33±4.94 mg/dL; UA= 10.13±9.04 mg/dL; and Ph= 4.55±1.08 mg/dL. A strong positive correlation was observed between serum calcium and stone calcium (r=0.747, p=0.001) and between stone calcium and urine uric acid (r=0.813, p=0.001). Conclusion: A significant relationship was observed between stone calcium and serum calcium.
A Case Series Reflecting Airway Difficulty Challenges: Insights into Intubation and Extubation for Large Retrosternal Goitres

Retrosternal goitres, often due to longstanding thyroid enlargement, can compress critical structures like the trachea and oesophagus, necessitating thyroidectomy. Managing the airway while ensuring patient safety presents a significant challenge for anaesthesiologists. This case series explores the complex airway management in three patients with large retrosternal goitres undergoing total thyroidectomy. The patients, aged 50, 60, and 73, presented with long-standing neck swelling, tracheal deviation and symptoms including breathlessness, dysphagia and hoarseness of voice. The goitres had progressively enlarged over many years, leading to significant tracheal compression and deviation, which posed a high-risk for airway obstruction during surgery. Given these challenges, Awake Fiberoptic Intubation (AFOI) was chosen to secure the airway while minimising the risk of airway loss. AFOI was performed under conscious sedation with dexmedetomidine and local anaesthesia, providing effective intubation with minimal discomfort and stable haemodynamics. This approach was critical in managing the anticipated difficult airway due to the retrosternal extension of the goitres and their impact on surrounding structures. Postoperatively, the patients were kept intubated to prevent tracheomalacia, a potential complication arising from prolonged tracheal compression. Tracheomalacia, characterised by the weakening of tracheal walls, can lead to airway collapse after extubation. To ensure airway stability, extubation was delayed until a satisfactory cuff-leak test was performed 24-36 hours after surgery. This case series emphasises the importance of careful preoperative planning and the use of AFOI in managing patients with large retrosternal goitres to avoid a ‘can’t intubate, can’t ventilate’ situation. The successful management of these cases highlights the effectiveness of AFOI in reducing perioperative risks and ensuring patient safety, particularly in scenarios where difficult airway management is anticipated. By implementing appropriate postoperative protocols, the risk of complications such as tracheomalacia can be significantly reduced, leading to improved surgical outcomes.
