Ecological niche modelling of five gorgonian species within the shallow rocky
habitat of the french mediterranean coast
Authors: Blouet S. , Bramanti L. , Guizien K.
Published: June 2024

Engineer species, such as gorgonians, provide several ecosystem services and play
a significant role in the maintenance of biodiversity. We tested an ecological niche
modelling approach using a unique dataset of spatialized inventories on a regular grid
(< 800 m) replicated in 2013 and 2020 along 450 km of coastline for five gorgonian
species commonly found in the Mediterranean shallow habitats (10-50 m deep). Ten
non-correlated environmental predictors derived from the most advanced geomorphological
and hydrological data were used to assess the ecological niche of the five species using
maximum entropy (Maxent). The model confirmed that different combinations of depth,
rugosity, sea surface and bottom temperature, bottom flow speed and turbidity explain
the different gorgonian’s distribution. The reduction of the number of presence
observations did not alter the quality of the prediction as long as the observation
points were spread over the entire variability range of predictors. The latter can be
achieved by only including presence observations from highly protected zones of the
marine protected areas of the region. Our results provide a greater understanding of the
factors shaping the distribution of five gorgnian species commonly found in
Mediterranean shallow areas.

Published: June 2024

Junto a las vertientes del río Cauca, entre las cordilleras de los Andes, existe una región colombiana cuyo paisaje es único, exótico y seductor. En esta región se produjo una migración a finales del siglo XIX que devino a la transformación territorial del Eje Cafetero y con esta, la consolidación de una cultura particular donde uno de los principales protagonistas es la guadua. Cuando se recorre el territorio y se trabaja con esta especie de bambú no solo se genera una relación con un material, sino también con un tejido comunitario, con el ecosistema de donde proviene y con el legado cultural que heredamos. Considerando los conceptos de La Poética del Espacio de Gastón Bachelard (Bachelard, 2000) se plantea transitar entre las escalas y fractales que componen esta planta: desde el cuerpo, la casa y el territorio. Este artículo aborda una mirada que integra lo sensible, la cultura, y diversas ópticas que surgen del encuentro durante el Taller de Domocaña (Ospina & Garzón, 2017), una experiencia de construcción con guadua y tierra, en el icónico Paraíso del Bambú y la Guadua, en Montenegro, Quindío.

In The Andes Mountain range, side the Cauca river it´s a unique landscape. Migration changed the Eje Cafetero territory at late XIX century, and Guadua culture emerge. Working with this material involves a dialogue with the plant, it´s community, with the ecosystem and with the cultural legacy inherited.

Non-Invasive Blood Sugar Measuring Tool Using Arduino-Based Linear Regression Method
Authors: Ningsih Nilu Widia , Yanti Indri , Pauzan Muh
Published: June 2024

Diabetes Mellitus is a disease characterized by high blood sugar levels caused by decreased production or function of the hormone insulin in the body. Traditional tests are usually invasive, involving skin puncture to obtain a blood sample, which can be unsuitable for some sufferers. Non-invasive methods provide a viable alternative for monitoring blood sugar levels. This research aims to create an Arduino-based non-invasive blood sugar level measuring device, leveraging the optical property of laser absorption in liquid media, detected by a photodiode sensor. The primary objective is to develop a device that accurately measures blood sugar levels without the need for invasive procedures. The photodiode sensor outputs voltage, which is then converted into blood sugar level (mg/dl) using a linear regression equation. The derived linear regression equation is y = 31.401 + 36.002x, with a previously obtained correlation value of 0.971 between voltage and blood sugar levels at a significance level of 0.01. The average error value (errata) of this device is 0.0905. The smallest measurement error was observed in patients C and Q, at 0.01 or approximately 1%, while the largest error was in patient L, at 0.22 or around 22%. The contributions of this research include the development of a non-invasive, accurate, and cost-effective method for blood sugar monitoring, potentially improving patient compliance and comfort.

Published: June 2024

Las zonas periurbanas se encuentran atravesadas por tensiones y conflictos, y en ocasiones se vinculan al empleo de plaguicidas utilizados en las actividades agrícolas, cuya aplicación es responsable de provocar contaminación ambiental y afecciones en la salud de pobladores. Este trabajo sistematiza la experiencia de un muestreo participativo para evaluar la exposición a plaguicidas en un barrio del periurbano del Partido de General Pueyrredón (Buenos Aires, Argentina), con la finalidad de fomentar acciones organizativas para promover actos de reclamo. Se emplearon metodologías participativas en los distintos momentos del desarrollo de las actividades: diagnóstico, planificación y diseño del muestreo, análisis y divulgación de resultados. En una primera instancia, el diagnóstico visibilizó y construyó una historia común de las problemáticas ambientales y de salud en el barrio. Se recolectaron 23 muestras durante 5 eventos de lluvia distintos, desde diciembre de 2019 a marzo de 2020, detectándose glifosato en el 27,6% de los análisis. Dichos resultados permitieron concluir que los habitantes del barrio se encuentran expuestos a plaguicidas a través del aire, con posible impacto en la salud. Asimismo, el trabajo consolidó estrategias participativas en propuestas de investigación posteriores. Para finalizar, se destaca el rol de una ciencia con perspectiva crítica y cómo el conocimiento generado puede incidir en las relaciones de poder en el territorio, poniéndolo en debate con la ciencia ciudadana. Se concluye que es trascendente una justicia ambiental y epistémica para fortalecer la participación, y así poder reivindicar un ambiente sano y el derecho a la salud.

Published: June 2024

El siguiente artículo es el resultado del trabajo realizado en el marco del proyecto de Extensión Universitaria: “Hábitat popular e iniciativas socio-comunitarias de integración urbana en barrios populares de Comodoro Rivadavia (Chubut)”. Como parte de sus objetivos, se pusieron en marcha metodologías participativas de investigación-acción en un barrio popular de la ciudad de Comodoro Rivadavia, como es la Extensión Abel Amaya. A lo largo de este devenir, las complejidades propias del espacio urbano y del habitar en condiciones deficitarias, no sólo llevaron a la puesta en marcha de procesos participativos de investigación, sino también a la articulación con organizaciones, referentes e instituciones, tal como las “Mujeres de la Huerta” quienes resisten y generan estrategias de sostenibilidad de la vida a través de la producción de hortalizas y frutales, a pesar del contexto adverso en el que habitan. La articulación con ellas no sólo propició dar cuenta de las complejidades del barrio y la ciudad sino que también formó parte de las iniciativas del proyecto que buscaron generar acciones y repercusiones más estructurales sobre la integración socio urbana del barrio hacia el largo plazo.
La Agroecología y la Extensión Crítica como propuesta política para la resistencia del campesinado
Authors: Guedes Bica Emiliano , Tonolli Alejandro Javier , García Ferreira Rodrigo , Viani Martin
Published: June 2024

El campesinado latinoamericano representa gran parte de la población rural y ha sido históricamente asociada a diferentes grados de pobreza, lo que la ha convertido en un sector de interés para las políticas públicas de desarrollo rural. El avance de las relaciones capitalistas en el campo ha profundizado los procesos de concentración de los recursos productivos, apropiación y sobreexplotación de los bienes naturales y han generado procesos de diferenciación social con tendencia a la proletarización campesina. En este contexto, desde el pensamiento crítico latinoamericano y en fuerte vínculo con los movimientos sociales campesinos, surgen propuestas críticas a los clásicos modelos de desarrollo y extensión rural, como la agroecología y la extensión crítica. El presente trabajo busca aportar a la comprensión de cómo, desde los desarrollos conceptuales y las propuestas de la extensión crítica y la agroecología, se generan aportes a la resistencia del campesinado. A partir de presentar las dinámicas de inserción del campesinado en el capitalismo contemporáneo y los aportes teórico-metodológicos de la agroecología y la extensión crítica, se puede señalar que ambas abordan aspectos que hacen a la resistencia individual y colectiva del campesinado. Por las perspectivas políticas que comparten se considera que la agroecología y la extensión crítica se complementan en un campo de estudio y acción, donde la primera propone una propuesta técnico-política para el manejo de agroecosistemas, y la segunda permite accionar y reflexionar sobre procesos de transformación territorial.

BRICS countries are not only striving to gain more political and economic clouts in the developing world but are also influencing global governance. However, each one is facing its own economic concerns and challenges. For instance, India has been witnessing a severe economic slowdown, while Brazil is maintaining a low growth rate along with persistent high inflation and unemployment problems. South Africa has been mired with low growth rate, rising youth unemployment, high debt and inequality. China has been suffering from a sluggish growth on account of the trade war with the US, and Russia has massively suffered from US and EU sanctions. Despite these problems, they are trying to lay a robust foundation of cooperation with the countries in the Global South amid their rising discontent over perceived Western dominance of the global institutions. With this background, our main focus here is to comprehend socioeconomic dimensions from a comparative assessment to develop an understanding and visualize their relative developmental positions over the last three decades (1990 to 2020). Analyzing the data, the study clearly observes visible diversities within them. While China’s socioeconomic dimensions have improved remarkably, followed by India, South Africa could achieve relatively only with minimal success. It demonstrates that certain BRICS countries while achieving significant strides in their socioeconomic development outcomes, others are encumbered and struggling with challenges over the last three decades (1990 to 2020) without witnessing similar success and yet to overcome those challenges. The uneven economic progress of economies needs to be addressed by individual economies by laying down efficient economic policies, which have been falling short of the average progress in any economic development parameters if their economic and social cooperation needs to be strengthened towards achieving higher economic progress by mutually benefitting from their stronger socioeconomic ties and simultaneously exert greater influence in the world stage.
Improvement of crystallization behavior of polylactide using modified chitin whisker as nucleating agent
Authors:   , Passornraprasit Nichaphat
Published: June 2024

This work focuses on the enhancement of crystallization behavior of polylactide (PLA). The small crystalline of polymer was used to induce nuclei for crystallization. The small crystalline of chitin whisker (CW) was prepared by acid hydrolysis. In order to enhance the compatibility between CW and PLA matrix, CW was grafted with acid terminated poly(D,L-lactic acid) (PDLLA) by coupling reaction to obtain PLA-g-CW. Then, the CW and PLA-g-CW were used as nucleating agents by compounding with PLA pellets at various contents from 0.1-0.3 phr by cast film extrusion. The SEM images of nanocomposites showed more agglomeration of whiskers with the increasing of CW or PLA-g-CW contents. Nevertheless, PLA/PLA-g-CW exhibited smaller size of agglomerated particles and better dispersion comparing to PLA/CW at same compositions due to the compatibility between CW and PLA was increased by grafting with PDLLA. The SEM images related to the DSC and POM results which indicated that the PLA-g-CW nanocomposite showed more effective nucleating agent of PLA than CW because of their well-dispersion. The introduction of PLA-g-CW at 0.1 phr significantly decreased the Tcc and increase Tc of nanocomposite. Moreover, PLA/PLA-g-CW0.1 also exhibited the highest degree of crystallinity comparing with the others. Therefore, PLA-g-CW at 0.1 phr was the most effective nucleating agent which enhanced the crystallization rate and degree of crystallinity of PLA.

Published: June 2024

Atrazine and paraquat are widely used to control weeds in the agricultural areas. The residue of herbicides can harm the environment and living things. In this research, nanoporous carbon derived from melamine based polybenzoxazine or NPC-PBZ-m was used as an adsorbent for atrazine and paraquat analysis. NPC-PBZ-m was synthesized by sol-gel and pyrolysis processes. The characteristics of sorbent were investigated by FTIR, BET, XPS, and FE-SEM. For atrazine determination, NPC-PBZ-m pre-concentration column combined with a colorimetric detection based on a Konig’s reaction and HPLC-UV at 222 nm were developed. The parameters affecting the adsorption performance were optimized. The reusability of the NPC-PBZ-m column was over 8 cycles. For colorimetric analysis, the orange-red polymethine compound was developed by using 6 (%w/v) of p-Anisidine. The HPLC-UV and colorimetric analysis showed a good linearity in the ranges of 5–30 µg/L and 10–30 µg/L with correlation coefficients of 0.9988 and 0.9979, respectively. The method detection limit (MDL) and method quantitation limit (MQL) of HPLC-UV analysis method were 1.05 µg/L and 3.45 µg/L while UV-Vis analysis method were 2.26 µg/L and 7.46 µg/L, respectively. The recoveries from spiked samples for HPLC analysis was in the range of 98–105% while colorimetric analysis was in the range of 100–107%. Moreover, NPC-PBZ-m combined with colorimetric analysis using glucose reagent showed a good performance for paraquat determination. The NPC-PBZ-m was activated with 0.1 M KOH before use. The suitable ratio between weight of NPC-PBZ-m and the volume of 0.1 M KOH was 1:1 (% w/v). For the desorption step, 2 mL of the 70:30 (% v/v) of 1 M HCl:MeOH was used. The dynamic range was found to be from 0.05–1 µg/mL with correlation coefficient of 0.986.

Movements and monuments: student movements for “democracy” in 1973 and 2020 and public monuments in Thailand
Authors:   , Turingan Gil
Published: June 2024

"Thai democracy" is usually defined from the statist perspective. It is frequently associated with the bureaucratic elite, military, capitalists, middle class, and the monarchy. This qualitative historical study aims to explain the definition and development of Thai democracy using a different lens—a viewpoint of Thailand's 1973 and 2020 student movements and public monuments. It follows the historical research design and analyzes historical accounts to understand the installation, purpose, symbol, meaning, and transformation of the Democracy Monument, the Constitution Monuments, replicas of the Democracy Monument, the 14th of October 1973 Memorial, and the Victory Monument. Through student demonstrations, protesters transformed these public monuments into venues of democracy and challenged their symbols and meanings. Given the relationship between the student movements and public monuments and the operational definitions and characteristics of democracy in the Thai political setting, it is noteworthy to examine how the Thai student activists define their notion of democracy using these monuments. This study uses various theories on political spaces, public memory, and urban social movements to analyze the data collected from primary and secondary sources. It also applies existing discourses on Thai democracy to weave the connection between the student movements and public monuments in Thailand.

Authors: DOSKU Lediano
Published: June 2024

The ever-increasing reliance on networked systems has brought about a heightened need for robust network security measures. This diploma thesis aims to explore the effectiveness and practicality of employing honeypots as a means to enhance network security. Honeypots are decoy systems that are strategically deployed to attract potential attackers and gather valuable information about their tactics, techniques, and motives. By analyzing the data collected from honeypots, network administrators can gain crucial insights into emerging threats and vulnerabilities, thereby enabling them to fortify their network defenses. This research project will commence with an in-depth examination of honeypot concepts and classifications. It will delve into the various types of honeypots, including high-interaction, low-interaction, and hybrid honeypots, and their respective strengths and weaknesses. Furthermore, the study will explore the deployment strategies and legal considerations associated with honeypots, addressing ethical concerns and potential implications. Case studies will be conducted to showcase the practical applications of honeypots in real world, that help in detecting, deflecting, and mitigating potential cyber threats. In addition to their defensive capabilities, honeypots can play a vital role in understanding attacker behavior, such as their tactics, motives, and skill levels. This thesis will explore the potential of honeypots as early warning systems, enabling network administrators to proactively adapt their security measures and effectively counteract emerging threats. Key words: high-interaction, low-interaction, hybrid, hacker, firewall, cyber threat, data, log, threat intelligence, false positive, false negative, IPS, IDS, SIEM, OSINT.

Published: June 2024

O crescimento das espécies vegetais é diretamente influenciado por fatores bióticos e abióticos. Com isso, objetivou-se identificar variáveis que influenciam no incremento corrente anual – ICA da área basal, em duas áreas, considerada como “menos conservada” e “conservada” no Semiárido Pernambucano, Brasil. Os dados dendrométricos foram oriundos de 40 parcelas permanentes de (20 m x 20 m), nos anos de 2008 e 2011 a 2019, as mensurações foram realizadas nos indivíduos e fustes com circunferência a 1,30 m do solo ≥ 6 cm. Os dados ambientais foram provenientes do Instituto Nacional de Meteorologia e da Agência Pernambucana de Águas e Climas. Aplicou-se correlação de Spearman entre o ICA e as variáveis ambientais, diante o problema de medidas repetidas, foi utilizado o modelo de regressão linear misto: CAIi = (β0 + αperíodo + λespécie) + βnVdendrométricasn + βmVambientaism + ϵi, consideraram-se os efeitos aleatórios o período e as espécies, e os de efeitos fixos as variáveis dendrométricas e ambientais. Quanto à significância das variáveis no ICA, notou-se influência para a área menos conservada apenas em relação aos efeitos fixos, já na área conservada foi significativo quanto aos efeitos fixos para as variáveis dendrométricas. Em geral o modelo mostrou boa performance, distribuições dos resíduos, sem outliers. Apesar de ter apresentado influência das variáveis ambientais apenas na menos conservada, se faz necessário o monitoramento por longo período, de modo que ultrapasse os eventos de secas sazonais.

O mogno africano (Khaya grandifoliola) é uma espécie arbórea que vem ganhando espaço no mercado florestal, apresentando utilidade nas mais diversas utilizações, principalmente em território brasileiro, onde é o principal substituto da madeira do mogno brasileiro. O objetivo deste trabalho foi realizar uma análise de trilha entre a resposta da solução nutritiva ao tratamento com cádmio e as demais variáveis e atributos estudados: aminoácido, nitrato, proteína, amônio, redutase, IDM, cádmio. O experimento foi conduzido em casa de vegetação. A princípio, as mudas foram habituadas para posteriormente serem levadas ao tratamento, onde a aplicabilidade se deu pelo cloreto de cádmio monohidratado (CdCl 2.H2O) de acordo com a solução nutritiva. O delineamento experimental foi inteiramente casualizado (DIC), misturado em cinco concentrações (0; 10; 20; 30 e 40 mg L-1) com sete repetições, totalizando 35 unidades experimentais. Para realizar o exame comparativo, os dados foram submetidos à análise de variância, seguida de análise de regressão. A análise de trilha permitiu verificar diretamente que doses crescentes de tratamento com Cádmio (CAR) refletiram em correlação negativa com o teor de aminoácidos (TAA) nas raízes das plantas de mogno. O estresse abiótico, que foi a exposição a um produto químico tóxico (cádmio), diminuiu, neste caso, a capacidade das plantas de sintetizar aminoácidos. O aumento das doses de tratamento com cádmio (CAL) refletiu em correlação negativa com o teor de proteína na folha (PRL) das plantas de mogno. Evidentemente, quanto maior a concentração de cádmio, maiores serão os danos aos sistemas metabólicos do mogno. Com este estudo, evidenciamos que excesso de cádmio no solo afeta o desenvolvimento de mudas de espécies florestais como o mogno.

A espécie herbácea rizomatosa Hedychium coronarium J.Koenig é de origem asiática e ocorre como invasora na maioria dos estados do Brasil. O objetivo do estudo foi avaliar a influência de H. coronarium sobre as comunidades de herbáceas terrícolas e de regeneração natural de lenhosas em um remanescente de Floresta Ombrófila Mista Aluvial em Curitiba - PR. As comunidades foram amostradas considerando-se dois tratamentos: (EC) elevada cobertura de H. coronarium (>60%); (BC) baixa cobertura de H. coronarium (<30%). Foram avaliadas duas comunidades: i) espécies herbáceas (incluindo subarbustivas) e ii) plântulas de espécies lenhosas entre 15 cm - 130 cm de altura. No EC, H. coronarium apresentou cobertura média de 78,06%, sendo registradas apenas cinco espécies herbáceas nativas e 24 lenhosas nativas. No BC, a cobertura média da invasora foi de 6,29%, com registro de 17 herbáceas nativas e 37 lenhosas nativas. A herbácea nativa mais representativa foi Christella dentata (Forssk.) Brownsey & Jermy, enquanto, dentre as lenhosas, destacou-se Myrcia selloi (Spreng.) N.Silveira por sua frequência e abundância. A abundância das lenhosas no EC foi aproximadamente quatro vezes menor que no BC, mostrando que a elevada densidade de H. coronarium exerce influência negativa nas comunidades vegetais nativas. A elevada cobertura da espécie invasora resulta na redução da riqueza de espécies e do número de indivíduos nas comunidades, tanto de herbáceas quanto da regeneração de lenhosas.

Se indagó determinar los tratamientos y sustratos más efectivos para la germinación de semillas de Juglans neotropica. Se realizaron dos experimentos: en el primero se utilizaron cinco tratamientos físicos, mientras que en el segundo se combinaron tres tratamientos físicos y tres sustratos, en un diseño completamente al azar. Se monitoreó la germinación de forma diaria, a partir de los 30 días después de la siembra, y se evaluó la capacidad de germinación y la distribución de la germinación en el tiempo, considerando variables como: el porcentaje y vigor de germinación, tiempo promedio de germinación, coeficiente e índice de velocidad de germinación y coeficiente de uniformidad de germinación. Se encontró que los tratamientos de pregerminación con temperaturas de 40 y 50°C en horno con ventilación forzada durante dos horas, así como el testigo, presentaron diferencias significativas en todas las variables evaluadas, excepto en el coeficiente de uniformidad, en comparación con los tratamientos de escarificación con lijado. El mayor porcentaje de germinación acumulada (76%) se obtuvo con los tratamientos pregerminativos a una temperatura de 40°C en estufa con ventilación forzada durante dos horas. La interacción entre los sustratos y los tratamientos pregerminativos no mostró diferencias significativas, en las variables germinativas analizadas. Cabe destacar que las semillas de Juglans neotropica presentan una germinación asincrónica.

O clima da região é AWI,  com precipitação anual entre 1.680 a 2.580 mm, com estação seca entre maio e setembro. O delineamento foi inteiramente casualizado em esquema fatorial 2 x 2 com seis repetições e quatro tratamentos: a) Clone I144 com acesso do gado aos 9 meses (TR1); b) Clone I144 sem acesso do gado aos 9 meses (TR2); c) Clone VM01 com acesso do gado aos 9 meses (TR3); e d) Clone VM01 sem acesso do gado aos 9 meses (TR4). Os dados foram coletados das 16 árvores centrais de cada parcela, aos 9, 12, 19, 24, 32 e 36 meses de idade. Realizou-se a medição de altura total (HT), diâmetro à altura do peito (DAP) e o volume individual com casca de cada fuste para cada clone foi obtido por meio de cubagem rigorosa. Foram geradas curvas de crescimento em função da idade para HT, DAP e Volume por ha, utilizando o modelo Logístico. O clone VM01 apresentou maior sobrevivência, diâmetro e volume por ha em comparação ao clone I144, com maiores valores destas variáveis para o tratamento que não teve a entrada precoce dos animais. O Clone VM01 apresentou estimativas de produção máxima de volume por hectare 83,8% superior ao do clone I144. A entrada precoce dos animais no sistema silvipastoril influenciou negativamente o crescimento e a sobrevivência dos clones de eucalipto.

Türkiye Cumhuriyeti’nin kuruluşunun ilk yıllarında milli eğitim sisteminin oluşturulması kapsamında değerlendirilen ve kültür politikasına önemli etkileri olan bazı düzenlemeler Türk kütüphaneciliğinin bugünlere kadar gelen geleneğinin yasal altyapısının oluşmasında önemli bir yere sahiptir. Çalışmanın amacı Osmanlı Devleti’nde eserlerin korunduğu bir yer olan ve belli kullanıcılar tarafından istifade edilen kütüphanelerin, özellikle Harf Devriminden sonra koleksiyonlarını yeniden oluşturarak Türk halkını çağdaş medeniyet seviyesine çıkarabilmek adına yapılan reformların halka anlatılıp milli bilincin oluşturulmasında aracı kurum olarak kullanıldığını kanıtlamaktır. Çalışma Milli Mücadele Döneminden itibaren 20 yıllık bir süreci kapsadığından (1920-1940) kütüphanecilik faaliyetlerine genel olarak değinilmiş olup Cumhuriyet’in ilk yıllarında gerçekleştirilen kütüphanecilik alanında atılan çağdaş adımların Türk Kütüphaneciliğinin gelişimine olan katkıları irdelenmiştir. Yöntem olarak; geçmişte yaşanmış olayların ortaya konulması veya bir sorunsalın geçmişle olan ilişkisinin irdelenmesinde başvurulan tarihî yöntem benimsenmiş, veri toplama tekniği olarak arşiv araştırması ve literatür taraması kullanılmıştır. Sonuçta; eğitimli insan gücünün önemli bir kısmını savaşlarda kaybetmiş bir toplumda Cumhuriyet’in ilk yıllarından itibaren okur-yazar oranını artırmak, yeni harflerle okuma-yazma öğretmek, halkı kitap okumaya ve kütüphane kullanmaya alıştırmak için aracı bir kültür kurumu olarak görülen kütüphanelerin bu misyonu gerçekleştirmekte başarıya ulaştığı tespit edilmiştir. Kütüphanecilik tarihi için önemli olan bu faaliyetlerin bir çalışmada topluca değerlendirilmesi çalışmaya özgün bir nitelik vermektedir.
Tumor neuroepitelial disembrioplásico. Presentación de un caso atípico.
Authors: Alemán Bacallao Alfredo
Published: June 2024

Se presenta el caso de un paciente con un tumor neuroepitelial disembrioplásico (TND) de localización y comportamiento clínico atípico con objetivo de describir la conducta diagnóstica-terapéutica y el seguimiento instaurado.
Paciente masculino de 44 años de edad que presenta un cuadro de paresia facial central y monoparesia braquial izquierda de dos meses de evolución. En estudio de resonancia magnética contrastada se define una  lesión quística frontal derecha con escaso edema perilesional, sin realce del contraste. Se realiza tratamiento quirúrgico guiado por Neuronavegación, lográndose la resección total de la lesión, con evolución favorable.
El TND es un tumor mixto neuroglial relacionado con epilepsia en niños y adultos jóvenes. Se localizan con mayor  frecuencia supratentorialmente en la corteza cerebral con predilección por el lóbulo temporal (80%). En RM se observan  quistes lobulados, bien delimitados, localizados en la corteza cerebral. La extensión a la sustancia blanca subcortical en casos como este se considera rara. El tratamiento predominante y más efectivo en los casos sintomáticos de DNT es la resección total del tumor.
La localización frontal y subcortical, el gran tamaño del quiste, y el debut clínico  con defecto motor en ausencia de convulsiones son formas inusuales en la presentación de los TND. Los estudios anatomopatológicos son claves en el diagnóstico y en la diferenciación de otros tumores gliales de comportamiento similar. La resección macroscópica total del tumor generalmente permite la curación y mejoría o desaparición de los síntomas.
Hemangioblastomas intradurales extramedulares: abordando una extraña patología
Authors: Fraire Jazmín Azul , Ruella Mauro , Villamil Facundo , Domecq Laplace Lucila , Mormandi Rubén , Cervio Andrés
Published: June 2024

Introducción: Los hemangioblastomas son tumores vascularizados, infrecuentes del sistema nervioso central (SNC), grado I por la OMS, intraaxiales, habitualmente localizados en el cerebelo y la retina que pueden ser esporádicos o asociados a la enfermedad de von Hippel Lindau (VHL). La topografía espinal es infrecuente y su presentación extramedular más rara aún. La literatura es escasa pero el tratamiento de elección suele ser quirúrgico.
Objetivo: Describir nuestra experiencia en el tratamiento de hemangioblastomas espinales extramedulares y revisar las características clínicas, radiológicas y su conducta terapéutica.
Descripción de los casos: Caso N°1. Paciente masculino de 67 años con cervicalgia progresiva durante 5 meses, debilidad distal predominante en miembros superiores izquierdos e hipoestesia en dedos de ambas manos. RM con lesión nodular intradural-extramedular en C3-C4. Caso N°2. Paciente masculino de 64 años con lumbociatalgia derecha durante 6 meses con déficit sensitivo. RM con lesión intradural-extramedular en L1-L2 a izquierda, con realce homogéneo post-contraste. Caso N°3. Paciente masculino de 22 años con enfermedad de Von Hippel Lindau que consulta con debilidad en miembro inferior izquierdo. RM con múltiples hemangioblastomas cerebelosos y en médula dorsal, destacándose una lesión voluminosa en T7-T9.
Intervención: Caso Nº 1. La cirugía consistió en laminectomía C3-C5 y resección del hemangioblastoma, con recuperación completa. Caso Nº 2. Se realizó laminectomía con resección total del hemangioblastoma con recuperación completa. Caso Nº 3. Se realizó laminectomía T7-T9 con exéresis completa del hemangioblastoma, con mejoría parcial postoperatoria e intervención.
Conclusión: Los hemangioblastomas son tumores infrecuentes; su presentación espinal y extraaxial es aún más singular. Al tratarse de lesiones altamente vascularizadas es de gran importancia la realización de una angiografía previa al procedimiento quirúrgico para diagnóstico y adyuvancia terapéutica. El estándar es el tratamiento quirúrgico y el empleo de monitoreo intraoperatorio con onda D y potenciales evocados es de gran utilidad para prevenir e identificar déficits neurológicos.
Recalibrado versus laminectomía para descompresión lumbar en pacientes mayores de 50 años: evaluación usando la escala de incapacidad de Oswestry
Authors: García Juan Pablo , Sanchez Ceron José Mauro Esteban
Published: June 2024

Introducción. La estenosis espinal lumbar, también llamada conducto lumbar estrecho, es el padecimiento más común de la columna en pacientes de edad avanzada, con una incidencia del 1,7 al 8%.
Objetivo. Evaluar qué técnica quirúrgica entre el recalibrado lumbar y la laminectomía tiene el mejor resultado para los pacientes mayores de 50 años que cursan con estenosis lumbar, en base a la escala de incapacidad por dolor lumbar de Oswestry.
Material y Métodos. Estudio observacional, retrospectivo y transversal. La muestra fueron los pacientes que cursaron con estenosis lumbar y se les practicó cirugía de recalibrado lumbar o laminectomía entre el 1 de enero del 2015 y el 31 de diciembre del 2020.
Resultados. Los pacientes intervenidos por laminectomía (85,7%) evolucionaron a una limitación funcional mínima y el 14,3% a moderada. De los pacientes intervenidos por recalibrado, el 64% evolucionó a una limitación funcional mínima, el 29,5% a moderada y el 6,5% a intensa.
Conclusión. El procedimiento de laminectomía genera mejores resultados para el paciente. Puede deberse a que en pacientes con conductos estrechos moderados a severos permite una mejor visualización de la duramadre, la remoción del ligamento amarillo en su porción central y hacia los recesos laterales. Además es más cómoda y eficaz descomprimiendo la raíz nerviosa del segmento, permitiendo el acceso al neuroforamen para su ampliación.

Brazilian Federal Public Administration, open data, technologies and the right to Information
Authors: Franco Fernanda Sathler Rocha
Published: June 2024

The interaction between digital government, the opening of data, regulatory instruments and actions aimed at the development of information technologies is a governance tool with many potentials, including for obtaining and sharing various important information for the Public Administration and for people. But, in addition to the already known benefits of efficiency, optimization and agility in the provision of public services, through data, how can digital information governance contribute to the creation of other public values, such as transparency, comprehensibility, participation, popular oversight and state accountability? This is the question that guides the present work, which sought to map the main regulatory framework and technical strategies of information governance within the scope of the Federal Public Administration of Brazil, as well as their potential contributions to the generation of public value, with emphasis on the degree of digital data openness and interoperability in the Brazilian federal public sector. As a methodology, the strategies of survey and content analysis of the main national regulatory instruments, the two main public instruments for monitoring open data and some strategies for the technological implementation of open and interoperable government in the country were adopted. Then, the current stage of data openness and transparency in the Federal Public Administration of Brazil was observed based on the indicators compiled by the Organisation for Economic Cooperation and Development (OECD) in 2022, with subsequent discussion through bibliographic references. It was concluded that Brazil is currently in a process of acquiring greater maturity in relation to data openness, digital interoperability and the creation of public value through digital information governance.
