Leading neuroscientific theories posit a central role for the functional integration of cortical areas in conscious states. Considerable evidence supporting this hypothesis is based on network changes during anesthesia, but it is unclear whether these changes represent state-related (conscious vs unconscious) or drug-related (anesthetic vs no anesthetic) effects. We recently demonstrated that carbachol delivery to prefrontal cortex (PFC) restored wakefulness despite continuous administration of the general anesthetic sevoflurane. By contrast, carbachol delivery to parietal cortex, or noradrenaline delivery to either prefrontal or parietal cortices, failed to restore wakefulness. Thus, carbachol-induced reversal of sevoflurane anesthesia represents a unique state that combines wakefulness with clinically relevant anesthetic concentrations in the brain. To differentiate the state-related and drug-related associations of cortical connectivity and dynamics, we analyzed the electroencephalographic data gathered from adult male Sprague Dawley rats during the aforementioned experiments for changes in functional cortical gamma connectivity (25–155 Hz), slow oscillations (0.5–1 Hz), and complexity (<175 Hz). We show that higher gamma (85–155 Hz) connectivity is decreased (p≤ 0.02) during sevoflurane anesthesia, an expected finding, but was not restored during wakefulness induced by carbachol delivery to PFC. Conversely, for rats in which wakefulness was not restored, the functional gamma connectivity remained reduced, but there was a significant decrease (p< 0.001) in the power of slow oscillations and increase (p< 0.001) in cortical complexity, which was similar to that observed during wakefulness induced after carbachol delivery to PFC. We conclude that the level of consciousness can be dissociated from cortical connectivity, oscillations, and dynamics.

SIGNIFICANCE STATEMENTNumerous theories of consciousness suggest that functional connectivity across the cortex is characteristic of the conscious state and is reduced during anesthesia. However, it is unknown whether the observed changes are state-related (conscious vs unconscious) or drug-related (drug vs no drug). We used a novel rat model in which cholinergic stimulation of PFC produced wakefulness despite continuous exposure to a general anesthetic. We demonstrate that, as expected, general anesthesia reduces connectivity. Surprisingly, the connectivity remains suppressed despite pharmacologically induced wakefulness in the presence of anesthetic, with restoration occurring only after the anesthetic is discontinued. Thus, whether an animal exhibits wakefulness or not can be dissociated from cortical connectivity, prompting a reevaluation of the role of connectivity in level of consciousness.

Published: November 2019

Trichoglossus haematodus (Linnaeus, 1771) is nectarivorous bird that feed on nectar as a source of carbohydrate. In captivity, it is not practical to provide a continued diet of nectar  from the flowers. Therefore, this study aimed to find other carbohydrate sources such as brown sugar as substitute nectar for T. haematodus. Twelve wild T. haematodus in four cages offered five types different brown sugar solution with different concentrations. Since brown sugar has low protein content, therefore the birds also  offered commercial baby biscuit  to meet the protein requirement.  The results showed that the birds like to consume all types of brown sugar solution with sugar concentration up to 40% . However, the siwalan brown sugar solution was the most favored by the bird. over the other type of brown sugar solutions (aren, coconut, sugar cane and regular commercial “palm” brown sugar).  Furthermore, the result showed that the birds prefer commercial baby biscuit was soaked in the brown sugar solution with concentration 20%. This study provides the information that the brown sugar solution based diet has potency as  an alternative carbohydrate source  to substitute nectar  for T. haematodus in captivity which  is more practical and can increase the survival rate in birds.

Published: November 2019

Biosorption is a new waste treatment technology that can eliminate toxic heavy metals. Biosorption can be considered as an environmentally friendly alternative technology to treat industrial liquid waste that is economically proper to use. One of them is biosorption that utilizes the microorganisms’ absorption ability, especially bacteria that can absorb heavy metals in waters, such as Enterobacter agglomerans. This research aimed to determine the ability of E. agglomerans in reducing heavy metals pollution in local river. The research employed the measurement of the effect of lead (Pb) to E. agglomerans growth using Optical Density (OD) at wavelength 600 nm. The colony numbers were calculated using a standard curve. While the ability of E. agglomerans to reduce heavy metals concentration in liquid media was measured using AAS with a wavelength of 240 nm. The results showed that lead affected the growth of E. agglomerans. The OD value has a negative relationship with the concentration level of Pb. The ODs were decreased from 2.867 to 1.242, using Pb level from 0 ppm to 20 ppm. Therefore, it proved that E. agglomerans could reduce heavy metals concentration in local river in Central Java Province. This research was the first report on E. agglomerans activity on heavy metal in contaminated water. This result can be used as a reference for industrial sites near the river to treat their wastewater before discharging it to the river body to preserve its water purity.

Salah satu unsur delik (delik bestadell) yang terdapat dalam Pasal 2 ayat (1) dan Pasal 3 UU No 31 Tahun 1999 tentang Pemberantasan Tindak Pidana Korupsi adalah dapat merugikan keuangan atau perekonomian negara. Dengan demikian, harus dimaknai bahwa kerugian negara dalam kedua pasal aquo bisa nyata (actual loss) maupun baru sebatas potensi (potential loss). Pasca keluarnya Putusan Mahkamah Konstitusi No. 25/PUU-XIV/2016, unsur kerugian negara dalam kedua pasal aquo harus berupa kerugian yang nyata (actual loss). Hal ini disebabkan Mahkamah Konstitusi menilai bahwa kata dapat dalam kedua pasal aquo bertentangan dengan UUD NRI Tahun 1945 (inkonstitusional) dan tidak memiliki kekuatan hukum mengikat. Permasalahan dalam penelitian, yaitu: (1) Bagaimana kedudukan unsur (bestandeel) kerugian keuangan negara dalam perkara korupsi sebelum dan setelah keluarnya Putusan MK Nomor 25/PUU-XIV/2016?; (2) Bagaimana prosedur penegakan hukum terhadap tindak pidana korupsi pasca keluarnya Putusan MK Nomor 25/PUU-XIV/2016? Penelitian ini adalah penelitian hukum normatif, dengan data sekunder sebagai data utama. Penelitian yang dilakukan terfokus pada Putusan MK No. 25/PUU-XIV/2016.One of the elements of the offense contained in Article 2 verse (1) and Article 3 of Law No. 31 of 1999 on Corruption Eradication is "can be detrimental to the finances or the economy of the country". Thus, it should be understood that the loss to the state in both passages quo It can be actual loss or potential losses. Post-discharge Constitutional Court Decision No. 25 / PUU-XIV / 2016, the state loss in both passages quo should be a real loss (actual loss). This is due to the Constitutional Court considered that the word "may" in the second chapter NRI quo contrary to the Constitution of 1945 (unconstitutional) and does not have binding legal force. The research problem, namely: (1) The position of the element losses to the state in a corruption case before and after the release of Constitutional Court Decision No. 25/PUU-XIV/2016?; (2) How does law procedure enforcement against corruption after the release of Constitutional Court Decision No. 25/PUU-XIV / 2016? This research is a normative law, with secondary data as the main data. Research conducted focused on the Constitutional Court ruling No. 25/ PUU-XIV/2016.

MODIFICATION OF IRON OXIDE CATALYSTS SUPPORTED ON THE BIOMASS BASED ACTIVATED CARBON FOR DEGRADATION OF DYE WASTEWATER
Authors: Amelia Shinta , Sediawan Wahyudi Budi , Mufrodi Zahrul , Ariyanto Teguh
Published: November 2019

Methylene blue is one of the dyes in textile industries which has a negative impact on the environment. This compound is very stable, so it is difficult to degrade naturally. Methylene blue can be harmful to the environment if it is in a very large concentration, because it can increase the value of Chemical Oxygen Demand (COD) which can damage the balance of environment ecosystem. Adsorption method by using activated carbon as the adsorbent is one of the most efficient and effective techniques in dye removal due to its large adsorption capacity. However, the adsorption method using activated carbon only removes the pollutant compounds to other media or phases. Other method that can be used includes Advanced Oxidation Processes (AOPs). This method has the advantage of being able to degrade harmful compounds in the waste through oxidation (oxidative degradation) processes. One method of AOPs is the process by using Fenton reagents. This study was aimed to prepare and characterize iron oxide/porous activated carbon catalyst. The type of porous activated carbon used was carbon from biomass derived carbon with microporous character. This biomass carbon is obtained from renewable natural products, namely coconut shell.The kinetics and adsorption models in the material will be derived and evaluated from the research data. Based on the research, it can be concluded that catalytic degradation is very effective for degradation of dye wastewater. Methylene blue degradation increases with the use of Fe2O3/activated carbon catalyst and the addition of hydrogen peroxide as the Fenton reagent. In addition, the pore structure difference in the catalyst also had a significant effect on the methylene blue degradation reaction resulting in increased capacity of methylene blue degradation reactions.

La generación de nuevo conocimiento requiere de la interacción del pensamiento humano con las necesidades del entorno en el que se desenvuelve y el aprendizaje previo en relación con el fenómeno objeto de estudio. En la actualidad, debido a la fluctuación constante del conocimiento derivada de la dinámica de las sociedades y de los retos que han suscitado procesos como la globalización, es indispensable una reflexión científica y filosófico, con el ánimo de encontrar nuevos campos y escenarios de investigación, métodos y enfoques de investigación para poder dar respuesta a dichas exigencias

En el presente ensayo se desarrolla la importancia del rigor metodológico en una evaluación curricular. Se parte de que para su valoración, por parte de los interesados, es exigido que el evaluador muestre el rigor con el que se ha realizado el proceso, de tal manera que sea posible evidenciar elementos que la hacen válida, confiable y creíble. Para ello, se sustenta el rigor de la evaluación con base en la articulación de aspectos significativos, valorativos, teóricos, metodológicos, de participación de los actores y de ética. Estos permiten delimitar y desarrollar el objeto por evaluar. Por lo tanto, cada uno de estos aspectos forman parte esencial del camino a seguir en un proceso evaluativo.

El presente ensayo tiene por objetivo reflexionar sobre el quehacer de la universidad pública costarricense y su responsabilidad en la formación para el desarrollo social. Lo anterior, entendido como uno de los múltiples retos que enfrenta la educación superior, de cara a las demandas que la función del conocimiento posee en el presente, y a la relación de estas con el desarrollo autónomo del conocimiento. Su planteamiento, defiende algunos asuntos débilmente abordados en estudios previos, y que se constituyen en elementos esenciales para una formación significativa, funcional y de impacto social, como son: a) La ética en la organización, b) La autoeducación de la universidad, c) La incidencia de las políticas curriculares en las prácticas promovidas, d) La transformación de la cultura docente para contribuir a mejorar la práctica, y e) La construcción del conocimiento para fundamentar criterios, tomar decisiones, solucionar problemas y construir proyectos de vida.

En el estudio se desarrolló una propuesta individualizada para promover desde el contexto familiar el desarrollo de la independencia en dos niños de cuatro años con discapacidad motora. La propuesta tiene como meta apoyar a la familia para que esta promueva destrezas en los niños y las niñas dentro del contexto familiar. Los resultados de este estudio muestran que cuando existe una guía para las familias de personas con discapacidad es más sencillo para estas iniciar procesos que de otra forma podrían verse pospuestos. A raíz de los resultados se recomienda crear propuestas de apoyo para padres y madres que les permitan construir sus propios procesos de crecimiento familiar y de desarrollo de la independencia en sus niños o niñas con discapacidad motora.

La forma en la cual se materializa la autonomía docente, concebida como parte del camino transitado por el colectivo docente en vías de apropiarse del conocimiento disciplinar y las competencias pedagógicas requeridas para el ejercicio de su función, es el eje de interés que provoca este escrito. Parte del éxito de la Educación Comercial se requiere de la urgida transformación de la función docente para el desarrollo de competencias claves provocadoras de la integración interdisciplinaria, el liderazgo académico y administrativo, y el uso de pedagogías contemporáneas. El grado de conciencia conseguido por el grupo docente sobre el impacto de los aprendizajes que promueve en el contexto educativo le permitirá empoderarse del conocimiento que resulte de la vinculación entre teoría y práctica, elemento clave para su autonomía profesional.

Este artículo explica cómo la modernidad desarrolla su propia modalidad de de educación para llevar adelante su consigna de conquistar la naturaleza y las consecuencias ambientales de esa concepción. Por lo tanto, se propone una nueva educación que se nutra del saber ecológico y deje atrás la misión fragmentaria y mecanicista del mundo, propia de la modernidad y, en su lugar, alumbre una conciencia alternativa con una nueva manera de relacionarnos con nuestro entorno natural y con nuestros semejantes.
Claves de la formación y el desarrollo humano en pedagogía
Authors: Reyes Rodríguez Alixon David
Published: November 2019

Recibido 11 de mayo de 2012 • Corregido 20 de junio de 2012 • Aceptado 28 de junio de 2012El trabajo que a continuación se ofrece ha sido desarrollado desde la experiencia y la anécdota de quien ha compartido diversos espacios educativos pasando por todos y cada uno de los niveles del sistema educativo venezolano. Tal posibilidad es pensada como una plataforma importante a fin de comprender las ideas de formación y desarrollo humano presentes en la institucionalidad venezolana en el tránsito escolar. Creemos que la idea de formación que tenemos como educadores debe ser repensada en tanto esta pase por el crisol de las historias personales, por el crisol de los rostros de aquellos que con nosotros comparten su tiempo, su interés y su disposición de vida. Niños, jóvenes o adultos; todos tienen una identidad, tienen particularidades, diferencias, pero también coincidencias. Tanto el maestro como la escuela, el currículo y el Estado no pueden pensar una educación para alguien a quien no conocen, para alguien a quien no descifran. En este sentido, presentamos algunas reflexiones producto de un trabajo etnográfico partiendo, en primer lugar, de la convivencia escolar, entrevistas, análisis de clases, observaciones, registros anecdóticos, entre otros. Como resultado reflexionamos sobre varias categorías, a saber: formación,  esperanza, diálogo, actitud y convivencia.

Desde 1995 se incluyen en los programas de estudio del Ministerio de Educación Pública (MEP) los temas de estadística y probabilidad en I y II Ciclos de la Educación General Básica. Como parte del análisis de la realidad de la enseñanza de dichos temas se realizó una investigación en dos regiones educativas del país, a saber: Heredia y Pérez Zeledón. Se indagó acerca de la formación universitaria que los docentes, en ejercicio en esas regiones, han tenido en dichas temáticas para enfrentar su enseñanza en las aulas, así como en los procesos de capacitación y actualización que han recibido. Al final de la investigación se evidenció la escasa formación universitaria en estos temas y la insatisfacción de los docentes al respecto, además del poco acompañamiento que han tenido durante el ejercicio de su profesión por parte de entes capacitadores.
Personal formador de docentes. Representaciones sociales de su profesión
Authors: Aguayo-Rousell Hilda Berenice
Published: November 2019

La investigación presenta los resultados de un estudio sobre representaciones sociales de docentes de 4 escuelas normales de la Ciudad de México (CDMX). El objetivo fue identificar creencias, opiniones, actitudes sobre diversos aspectos asociados con su función profesional, dado que dichas opiniones y creencias guiarán sus prácticas en su desempeño profesional. La muestra fue probabilística intencional constituida por 13 docentes con perfil profesional distinto y condiciones laborales diversas, se les aplicó una entrevista semiestructurada con 45 preguntas divididas en 4 apartados. Los datos se procesaron con el programa Atlas ti con base en las 3 dimensiones centrales de las RS: información, campo de representación y actitud. Entre los principales resultados se observa que sus creencias y opiniones sobre su quehacer profesional están atravesadas por el devenir histórico de dichas instituciones y la dependencia directa con la SEP. En los hallazgos se encuentra que sus representaciones sobre la profesión las relacionan con el sentido de responsabilidad y gusto por formar seres humanos; ser personas apasionadas de la docencia entendiéndola como entrega, dedicación, sacrificio, frustración, desilusión, situaciones vinculadas directamente con el desarrollo histórico y tradicional de esta profesión, pero no con la producción de conocimientos. En las conclusiones se reitera que los grupos docentes son parte fundamental de las escuelas normales y que estudiar y comprender sus pensamientos, creencias y prácticas es imprescindible para mejorar la calidad educativa en dichas instituciones, y generar propuestas de formación y actualización viables que realmente incidan en sus prácticas profesionales.
