This study took samples of coral mucus in 2010 at 3 (three) different locations, namely Bunaken (May); Morotai (September) and Raja Ampat (November), which focused on the analysis of gram-positive and gram-negative bacteria. The method used for field sampling is time swim, which is by diving at a depth of 5-10 meters for ± 30 minutes and randomly taking samples of coral mucus using siring or by taking directly on corals (reef branching). Mucus samples were analyzed by bacterial isolation in the laboratory. The result shows that there were differences between gram-positive and gram-negative bacteria in the three research sites and that gram-positive bacteria were higher or dominant. Further research that can identify the bacteria species and explain its relationship to the ecosystem is highly recommended.Keywords: Bacteria, Scleractinian coral, gram-positive and -negative, Bunaken, Morotai, Raja Ampat AbstrakPenelitian tentang karang keras (Scleractinian coral) yang terkontaminasi bakteri masih belum banyak dilakukan, terutama di perairan Indonesia.

Published: February 2020

Abstract
The active pixel image sensor based on a semi-floating gate transistor (SFGT-APS) has been proposed and investigated; however, the quantum efficiency (QE) and the sensitivity are too poor to meet low illumination intensity and high-speed application due to the shallow junction of photodiodes. In this work, we demonstrate a new structure, called buried photodiode semi-floating gate transistor active pixel image sensor (BSFGT-APS), which possesses enhanced QE, high sensitivity, and fast response speed. Moreover, BSFGT-APS has the same fill factor with SFGT-APS, which is 55% with a 1 μm2 photodiode in 0.13 μm process. The basic device characteristics were investigated by Sentaurus TCAD simulation, including potential of photodiode, transient response, dark current, conversion gain, and full well capacity.
Revista Vol 9 No 2. Educación, aprendizaje y otredad
Authors: Arboleda Aparicio Carlos 
Published: February 2020

El título de este número Educación, aprendizaje y otredad obedece, en primer lugar, a la reflexión que nos aporta el pedagogo español Pedro Ortega Ruiz, miembro del Comité de Calidad de la Red Iberoamericana de Pedagogía, Redipe, sobre la presencia de la ética y la antropología en la educación, proponiendo un nuevo enfoque en educación, un discurso que saque a la pedagogía de la rutina y del cansancio que provoca repetir siempre lo mismo. Manifiesta que la antropología y la ética atraviesan de principio a fin la acción educativa; que la educación, al igual que la ética, es un encuentro con el otro que nos demanda acogida y reconocimiento desde la autoridad de la vulnerabilidad de su rostro. Por otra parte, el grueso de los artículos que involucra la revista incluyen los procesos de aprendizaje, ámbito de la educación que no es posible fortalecer sin el recocimiento acontecimental del otro.
De la representación mental a la lectura comprensiva: un reto en estudiantes de EGB media
Authors: Yungán Pinda Carmen Elena 
Published: February 2020

Hoy en día, cada proceso educativo es cuestionado desde su eficacia y efectividad en el desarrollo de aprendizajes de los estudiantes. Uno de ellos tiene que ver con la comprensión lectora preocupante en el Ecuador en lo concerniente al bajo índice de motivación a la lectura que tienen los estudiantes, por las dificultades que ello conlleva, en la búsqueda de respuestas a esta problemática se hace un recorrido sobre la influencia de la representación mental en la lectura comprensiva, que es la base de todo proceso hasta llegar a la construcción conceptual, que en definitiva es el conocimiento que todo ser humano tiene entorno a algo. El estudio contrasta pensamientos y corrientes de autores que datan sobre la importancia tanto de la representación mental desde sus inicios con los hitos del desarrollo y las podas como también de la lectura comprensiva con lo referente a procesos cognitivos. Para dicho recorrido se utiliza el método científico en su fase de análisis y síntesis de la información a través del rastreo de lecturas científicas. Este análisis tiene como eje principal reflexionar sobre la importancia de que el docente comprenda la relación de la representación mental con la comprensión lectora y como ésta influye en el desarrollo del escolar.
Students’ ability to identify media bias in written press
Authors: Rivadeneira Barreiro María Piedad 
Published: February 2020

The intention of this study is to analyze the relationship between reading comprehension and students’ ability to identify media bias in written press. The participants for this study were sixty EFL students from a language department of an Ecuadorian university. There was no random assignment of participants to the control and experimental groups. Information was obtained from a questionnaire by Browne and Keeley (2004). Data was coded manually, and the outcomes showed no significant improvement in students’ ability to identify media bias referred to the variable “time”. Also, there was no significance in the interaction of the variable “time” and the variable “group”, and there was little difference in the two times the test was taken by both groups.
Effect of serum vitamin D levels on weight loss in obese patients doing aerobic exercises: A retrospective study
Authors: Karadağ Ahmet , Otu Meryem 
Published: February 2020

Objective: This study evaluates the effect of serum vitamin D (Vit D) levels on weight loss in obese patients during an aerobic exercise program.
Material and Methods: The study included 88 participants with body mass index (BMI) ≥25 kg/m2. A serum level of 25(OH)D3 >30 ng/ml was accepted as normal, 20–29 ng/ml as insufficient and <20 ng/ml as deficient. The obese patients were classified into three groups based on a serum level of 25(OH)D3. All participants enrolled on an eight-week aerobic exercise program. The BMI, body fat percentage (BF%) and body fat mass (BFM) of the participants were measured before and after aerobic exercise.
Results: No statistically significant differences were identified between the groups in the first and last measured BMI, BF% and BFM values (p>0.05). The differences between the first and last measured weights, BMI, BF% and BFM were statistically significant within the groups (p<0.05).
Conclusion: Aerobic exercise can lead to weight loss in obese patients, although the level of serum Vit D has no effect on weight loss in obese patients engaged in aerobic exercise.

Authors: Polat Büşra Sümeyye Arıca , Özen Akçay Övünç , Karadaş Ömer 
Published: February 2020

Objective: There is a complex interaction among to the ischemic cerebrovascular diseases, cognition and depression. The aim of present study is to investigate the relationship between lesion side and depression and attention deficit in patients with Middle Cerebral Artery (MCA) infarction.
Methods: This study was conducted on 41 patients with right and left MCA infarction. Beck Depression Inventory (BDI) was used for determination of depression severity of patients and Montreal Cognitive Assessment (MoCA) scoring was used for evaluation of cognitive status. Attention sub-test of MoCA score was also examined.
Results: 20 patients had right MCS. The mean age of the patients was 72.21 years. 51.2% of the patients were male. BDI mean score was found to be 11.25 in patients with right MCA infarction and 16.9 in patients with left MCA infarction (p:0.04). The total MoCA scores between two groups were similar (right/left MCA infarction: 20.8/21.3). It was seen to be lower attention sub-score in patients with right hemisphere effects compared to patients with left hemispheric lesion (3.1/5.9; p:0.00).
Conclusion: According to our findings, it is understood that attention of patients with right MCA infarction is more affected and patients with left MCA infarction is more depressed. In future studies, depression and attention affects which are at risk of developing after MCA infarctions should be evaluated in detail and should be put emphasis to rehabilitation of these areas.

Published: February 2020

Se obtuvieron carbones activados a partir de coronta de maíz (Zea mays) y pepa de ciruela (Spondia purpurae L.), los cuales fueron impregnados satisfactoriamente con quitosano. Las imágenes de microscopía electrónica de barrido de emisión de campo confirmaron la presencia de quitosano en cada uno de los carbones obtenidos.
Las propiedades adsorbentes y capacidad antimicrobiana frente a Escherichia coli fueron estudiadas y comparadas con las propiedades de dos carbones activados utilizados en filtros comerciales para la potabilización casera de agua. Los experimentos de equilibrio, empleando azul de metileno, mostraron que los carbones activados impregnados con quitosano poseen capacidades máximas de adsorción comparables con las de los carbones comerciales evaluados (entre 145 y 192 mg/g).
Los carbones activados impregnados con quitosano presentaron una mejor respuesta microbiológica que la de los carbones comerciales. Tal es así que se obtuvo una mayor reducción de Escherichia coli. Los carbones activados preparados a partir de coronta de maíz alcanzó un nivel de reducción tan alto como 96,3%. Mientras que para los carbones comerciales se tienen valores de reducción de menores a 60,3%.
Testing Densities and Refractive Indices of Extraterrestrial Ice Components Using Molecular Structures—Organic Compounds and Molar Refractions

Published: February 2020

Abstract
The use of infrared spectra to determine molecular abundances of icy astronomical objects and to study their chemistry requires laboratory measurements of reference spectra and related quantities, such as the index of refraction (n) and density (ρ) of candidate ices. Here we present new n and ρ measurements on ices involving over 30 C-, H-, and O-containing compounds, both acyclic and cyclic, representing seven chemical families. We examine the results in a way that is rare in the astrochemical literature, namely one in which data from an ice formed from molecules of a particular chemical family are compared to measurements on another member of the same family, such as of a homologous series or a pair of isomers. Apart from the intrinsic usefulness of the n and ρ data, a structure-based comparison can help establish trends and identify possibly spurious results. As liquid-phase data sometimes are used in low-temperature astrochemical work in the absence of solid-phase measurements, we compare our new ice results to those for the corresponding room-temperature liquids. We emphasize the use of our n and ρ data to compute the molar refraction (R

M
) for each of our ices, and how the resulting R

M
values compare to those expected from molecular structures. The use of calculated R

M
values and measured n values to calculate ice densities, in the absence of direct measurements, is also addressed.
Forming Diverse Super-Earth Systems In Situ

Published: February 2020

Abstract
Super-Earths and mini-Neptunes exhibit great diversity in their compositional and orbital properties. Their bulk densities span a large range, from those dense enough to be purely rocky to those needing a substantial contribution from volatiles to their volumes. Their orbital configurations range from compact, circular multitransiting systems like Kepler-11 to systems like our solar system’s terrestrial planets with wider spacings and modest but significant eccentricities and mutual inclinations. Here we investigate whether a continuum of formation conditions resulting from variation in the amount of solids available in the inner disk can account for the diversity of orbital and compositional properties observed for super-Earths, including the apparent dichotomy between single and multitransiting systems. We simulate in situ formation of super-Earths via giant impacts and compare to the observed Kepler sample. We find that intrinsic variations among disks in the amount of solids available for in situ formation can account for the orbital and compositional diversity observed among Kepler’s transiting planets. Our simulations can account for the planets’ distributions of orbital period ratios, transit duration ratios, and transit multiplicity; higher eccentricities for planets in single transiting systems than for those in multitransiting systems; smaller eccentricities for larger planets; scatter in the mass–radius relation, including lower densities for planets with masses measured with transit timing variations instead of with radial velocity; and similarities in planets’ sizes and spacings within each system. Our findings support the theory that variation among super-Earth and mini-Neptune properties is primarily locked in by different in situ formation conditions, rather than arising stochastically through subsequent evolution.
A Massive Star’s Dying Breaths: Pulsating Red Supergiants and Their Resulting Type IIP Supernovae
Authors: Goldberg Jared A. , Bildsten Lars , Paxton Bill 
Published: February 2020

Abstract
Massive stars undergo fundamental mode and first overtone radial pulsations with periods of 100–1000 days as red supergiants (RSGs). At large amplitudes, these pulsations substantially modify the outer envelope’s density structure encountered by the outgoing shock wave from the eventual core collapse of these

stars. Using Modules for Experiments in Stellar Astrophysics (MESA), we model the effects of fundamental mode and first overtone pulsations in the RSG envelopes and the resulting Type IIP supernovae (SNe) using MESA+STELLA. We find that, in the case of fundamental mode pulsations, SN plateau observables, such as the luminosity at day 50, L
50; time-integrated shock energy, ET; and plateau duration, t
p, are consistent with radial scalings derived considering explosions of nonpulsating stars. Namely, most of the effect of the pulsation is consistent with the behavior expected for a star of a different size at the time of explosion. However, in the case of overtone pulsations, the Lagrangian displacement is not monotonic. Therefore, in such cases, excessively bright or faint SN emission at different times reflects the underdense or overdense structure of the emitting region near the SN photosphere.
La géographie du pape François
Authors: de Charentenay Pierre 
Published: February 2020

Les différents voyages du pape François ainsi que le choix des cardinaux expriment ses priorités. Délaissant les grands centres, en particulier européens, celles-ci se portent sur les « périphéries ». Le rapport du pape à l’Europe est ambivalent. Mais son engagement poursuit l’internationalisation de l’Église et contribue à ouvrir le centre romain sur le monde.
Qu’est-ce que le réel ?
Authors: Ferry Jean-Marc 
Published: February 2020

Depuis le début du XX e siècle, la révolution de la physique a modifié notre compréhension de la réalité et notre façon d’habiter le monde. Elle nous confronte aujourd’hui à des hypothèses qui défient l’entendement commun. À ce défi que la science contemporaine pose à la philosophie, s’ajoute celui des témoignages venant du monde profane à propos de phénomènes extraordinaires que l’on ne peut ni accréditer ni réfuter. À ce double défi, le philosophe propose de répondre par la nécessité d’un élargissement de la raison au-delà de sa restriction positiviste.
Une liturgie plus humaine
Authors: Boselli Goffredo 
Published: February 2020

La réforme du concile Vatican II visait une meilleure adéquation de la pratique liturgique à la révélation évangélique. Plusieurs composantes, comme le déplacement de l’autel et l’introduction des langues vivantes, se voulaient en cohérence avec la manière de faire de Jésus. Les formes rituelles se rapprochent alors des formes élémentaires de la vie, de même qu’en Jésus, Dieu s’est rendu proche de l’humanité.
Prison Ethnography in Africa: Reflections on a Maturing Field
Authors: Martin Tomas Max , Jefferson Andrew M. 
Published: February 2020

On peut aujourd’hui affirmer que les études sur les prisons dans les pays du Sud sont arrivées à maturité. Dans cet article, nous nous appuyons sur près de vingt années de recherches ethnographiques sur les prisons « au-delà de l’Occident » pour analyser ce processus de maturation. Il n’est plus possible de considérer que les prisons africaines n’ont pas été soumises au regard empirique des sciences sociales ou que tout ce que nous savons sur le sujet est fondé sur des rapports relatifs au non-respect des droits de l’homme. Le champ a connu des progrès, aussi modestes soient-ils, tant en termes de couverture spatiale que de portée analytique. Nous montrons ici en quoi cette appréhension ethnographique de l’Afrique carcérale a suscité une reconceptualisation à contre-courant des prisons, en les considérant comme relationnelles et poreuses plutôt qu’asociales, non conformes et coupées du monde. Nous identifions également deux grandes tendances actuelles en matière pénale (l’extension du filet carcéral et la gestion de l’extrémisme violent) qui appellent à des recherches plus approfondies sur les prisons en Afrique et au-delà.
Un chef d’établissement bouc émissaire
Authors: Casanova Rémi 
Published: February 2020

L’article prend comme support un collège pour illustrer, analyser, critiquer deux thématiques : le phénomène du bouc émissaire à travers sa figure incarnée, ici le Principal du collège confronté à une problématique d’instabilité institutionnelle, de violence et de changement ; une méthodologie de recherche affiliée à l’analyse institutionnelle qui prend comme analyseurs les grandes thématiques du mécanisme du bouc émissaire (obstacles institutionnels ; rivalité mimétique ; tabous groupaux) ; en ce qui concerne la victime émissaire, l’étude suit son parcours depuis sa discrimination jusqu’à son exclusion (ici une auto-exclusion) en passant par sa stigmatisation et son affaiblissement relationnel et institutionnel. L’étude conclut que le bouc émissaire n’est pas sans ressources individuelles ou managériales. En ce qui concerne l’analyse institutionnelle, la grille de lecture par les thématiques et les étapes du mécanisme du bouc émissaire permet aux acteurs de la situation de replacer le processus dans un système qui les englobe tout en les responsabilisant.
La Gascogne toulousaine aux XIIe-XIIIe siècles
Authors: Mousnier Mireille 
Published: February 2020

La Gascogne toulousaine, pays de terres ingrates blotti dans le coude de la Garonne, n'est rien d'autre pendant longtemps qu'un angle mort. Comment une région aussi déshéritée sort-elle de son inertie pour entrer dans une dynamique de désenclavement, d'aménagement et d'intégration ? L'étude qui en est faite, à partir des acquis les plus récents de la nouvelle géographie humaine, envisage la croissance médiévale des xiie et xiiie siècles en bousculant quelque peu les méthodes traditionnelles de l'histoire rurale du Moyen Âge.
