VALIDATION OF ASMR2 SEA ICE CONCENTRATION DATA USING MODIS DATA
Authors: Cho K. , Nagao R. , Naoki K.
Published: June 2019

Abstract. Passive microwave radiometer AMSR2 was launched by JAXA in May 2012 on-board GCOM-W satellite. The antenna diameter of AMSR2 is 2.0 m which provide highest spatial resolution as a passive microwave radiometer in space. The sea ice concentration images derived from AMSR2 data allow us to monitor the detailed sea ice distributions of whole globe every day. The AMSR bootstrap algorithm developed by Dr. Josefino Comiso is used as the standard algorithm for calculating sea ice concentration from AMSR2 data. Under the contract with JAXA, the authors have been evaluating the performance of the algorithm. The sea ice concentration estimated from AMSR2 data were evaluated using MODIS data observed from Aqua satellite within few minutes after AMSR2 observation from GCOM-W. Since the spatial resolution of MODIS is much higher than that of AMSR2, under the cloud free condition, the ice concentration corresponds to the size of a pixel of AMSR2 can be calculated much accurately with MODIS data. The procedures of the evaluation are as follows. Firstly, MODIS band 1 reflectance were binarized to discriminate sea ice(1) from open water(0) and sea ice concentration of each pixel size of AMSR2 were calculated. In calculating sea ice concentration from MODIS data, the selection of the threshold level of MODIS band 1 reflectance is critical. Through the detailed evaluation, the authors selected 5% as the optimum threshold level. Then the AMSR2 sea ice concentration of each pixel was compared with the sea ice concentration calculated from MODIS data. The result suggested the possibility of estimating sea ice concentration from AMSR2 data with less than 10% error under the cloud free condition.

Published: June 2019

Abstract. Permafrost distributed in northeast China is the only high-altitude permafrost in China. The deformation monitoring over this permafrost region is of great importance to local climate change and ecological environments. This study focuses on the deformation monitoring of high-latitude permafrost in northeast China with time series InSAR technique. The spatial distribution characteristics, the annual deformation rates and the temporal deformation evolutions of permafrost could be retrieved from multi-temporal InSAR processing with Sentinel-1 TOPS datasets. This work concludes that time series InSAR technique could help to retrieve a comprehensive and reliable permafrost deformation, while a long time-series of displacements facilitated to better understand permafrost kinematics.

Published: June 2019

Abstract. We study the terrestrial water storage (TWS) and groundwater storage (GWS) changes in Canada and United States. We employ the separation approach from Wang et al. (2013) together with the improved GRACE data of Release 6 for a longer time span until December, 2016. The TWS signals from lake levels are derived from satellite altimetry data over the lakes while TWS signals due to soil moisture (SM) and snow water equivalent (SWE) changes from hydrology models. There are four significant trend anomalies in North America for both TWS and GWS changes. Two positive anomalies are found in Canada with their centers in the provinces of Saskatchewan and Quebec, respectively, due to increased precipitation and/or increased runoff in their surroundings. Two negative anomalies are shown in the United States with their centers in California and the northwest of Texas, respectively, which are due to decreased precipitation and, especially for California, high water usage for agriculture.
A HYBRIDIZATION OF AN IMPROVED PARTICLE SWARM OPTIMIZATION AND FUZZY K-MEANS ALGORITHM FOR HYPERSPECTRAL IMAGE CLASSIFICATION
Authors: Chen Q. , Jiang J. , Du M. , Zhou L. , Jing C. , Lu C.
Published: June 2019

Abstract. A particle swarm optimization (PSO) algorithm has been widely used in the field of remote sensing image classification. We proposed the IPSO-FKM algorithm, which use the improved PSO (IPSO) algorithm to optimize the initial parameters of the Fuzzy K-Means (FKM) clustering algorithm. We combine the crossover operator of genetic algorithms with PSO, and introduce the fuzzy membership degree of fuzzy mathematics into K-means clustering algorithm. Then we use the IPSO-FKM algorithm to optimize the classification results of the Hyperion remotely sensed images, and use FKM, IPSO, and IPSO-FKM to extract the land cover information on the wetlands in Dongting Lakes, China. The experimental results have been validated by the classification results of MLC and the field investigation data. The validation results have been evaluated from three perspectives: the overall classification accuracy and the Kappa coefficient from the pixel perspective, the intra-cluster distance and the inter-cluster distance from the feature perspective, and the partition coefficient and partition entropy from the information perspective. According to the comparison of IPSO and FKM algorithms，the IPSO-FKM algorithm has a better performance than the others in all three respects. Additionally, in terms of the fitness convergence, the IPSO-FKM algorithm has a better searching velocity and better convergence to lower the quantization errors compared with the other two algorithms.
LAND USE AND LAND COVER CLASSIFICATION USING HYPERSPECTRAL IMAGERY: EVALUATING THE PERFORMANCE OF SPECTRAL ANGLE MAPPER, SUPPORT VECTOR MACHINE AND RANDOM FOREST

Published: June 2019

Abstract. Land Use and Land Cover (LULC) information is an important data source for modeling environmental variables, so it is essential to develop high quality LULC maps. The hundreds of continuous spectral bands gathered with hyperspectral sensors provide high spectral detail and consequently confirm hyperspectral remote sensing as an appropriate option for many LULC applications. Despite increased spectral detail, issues like high dimensionality, huge volume of data and redundant information, mean that hyperspectral image classification is a complex task. It is therefore essential to develop classification approaches that deals with these issues. Since classification results are directly dependent on the dataset used, it is fundamental to compare and validate the classification approaches in public datasets. With this in mind, aiming to provide a baseline, four classification models in the relatively new hyperspectral HyRANK dataset were evaluated. The classification models were defined with three well-known classification algorithms: Spectral Angle Mapper (SAM), Support Vector Machine (SVM) and Random Forest (RF). A classification model with SAM and another with RF were defined with the 176 surface reflectance bands. A dimensionality reduction with principal component analysis was carried out and a classification model with SVM and another with RF were defined using 14 principal components as features. The results show that SVM and RF algorithms outperformed by far the SAM in terms of accuracy, and that the RF is slightly better than the SVM in this respect. It is also possible to see from the results that the use of principal components as features provided an improvement in the accuracy of the RF and an improvement of 28% in the time spent fitting the classification model.

Abstract. In this study, the deformation of Ayvacik Canakkale earthquake and aftershocks of 5.3 (Mw), which were observed on 6 February 2017 in Gulpinar Ayvacik and felt from the surrounding cities, were analyzed by InSAR and strain reduction technique. The earthquake is occurred at the Biga peninsula which is located at the south segment of North Anatolian Fault zone. The first shock (Ml = 4.8) started on 14 January 2017 in the region, and after the second shock (Ml = 5.4) on February 6, 2017, seismic storm continued with the large and small earthquakes. It was seen that 31 of these earthquakes have a size of 4 and above and occurred on the Tuzla fault. Since classical geodetic methods are not performed regularly and frequently, and are spatially provide point-based displacements, they are often insufficient to monitor sudden earthquakes. For this purpose, the deformation values were obtained along the line of sight (LOS) direction of Synesthetic Aperture Radar (SAR) sensor using Differential Interferometric SAR (DInSAR) method. For the geophysical analysis coulomb technique was applied and the continuity of the changes in the sea is determined.
EVALUATION OF A PSI-BASED CHANGE DETECTION REGARDING SIMULATION, COMPARISON, AND APPLICATION
Authors: Yang C. H. , Soergel U.
Published: June 2019

Abstract. Persistent scatterer interferometry (PSI) detects and analyses strong, stable, and coherent radar signals throughout a time series of SAR images. Such coherent signals are reflected from corner-reflector-like substructures in built-up cities, which are regarded as so-called PS points. Certain PS properties such as deformation velocity and topography height can be derived for scene monitoring. Previously, we introduced a PSI-based change detection to detect disappearing and emerging PS points along with their occurrence times. Such temporary PS points existing only during a certain period correspond to change events, e.g., mostly constructions in cities. The tests using TerraSAR-X images successfully identified where and when the construction events in Berlin took place in 2013. The results were compared and all agreed with the ground truth. In this study, we evaluate our method more deeply. A simulation test is conducted to evaluate the theoretical accuracy in space and time. We also compare our method with two classical approaches: image rationing and amplitude-based semi-PS detection. The computational requirements are revealed afterwards. Finally, potential applications are proposed and discussed. All of these works help us to better characterize our technique and learn the pros and cons.

Desenmascarando a Helena
Authors: Gómez Seijo Francisca
Published: June 2019

Diversas obras de arte de todos los tiempos han intentado representar la belleza absoluta y perfecta de Helena. Podemos imaginar nosotros mismos a una mujer de largos cabellos rubios (ondulados o no), de ojos azules (o verdes, o grises, o castaños), de nariz más o menos larga y estilizada, de labios finos o gruesos, de cara redonda o alargada… Los antiguos griegos también podían, desde luego, imaginar a Helena de todas estas maneras, pero los que asistieron a la puesta en escena original de la tragedia homónima de Eurípides proyectaron su particular noción de la belleza absoluta sobre una austera máscara con peluca que cubría la cabeza de un actor, el cual miraba hacia el público a través de dos huecos en el lugar de los ojos y le hablaba a través de una boca entreabierta inmóvil. En este breve estudio titulado «Desenmascarando a Helena» me propongo demostrar cómo logra Eurípides extraer el máximo potencial de caracterización de Helena a través de una convención (i.e., la máscara).

As Alexander says. The Alexander-dream motif in Plutarch’s Successors’ "Lives"
Authors: Romero-González Dámaris
Published: June 2019

La importancia de estar relacionado con Alejandro fue una pieza fundamental después desu muerte, y se manifestó cuando se le presenta en sueños a sus sucesores (el motivo del ‘sueño deAlejandro’). Plutarco introduce este motivo en sus Vidas en tres ocasiones (Eum. 6.5, Pyrrh. 11.2,Demetr. 29.1), todas ellas dentro de un contexto muy similar. Aunque la aparición de Alejandro ensueños en las Vidas podría considerarse como una invención plutarquea (y en dos sueños lo es),Plutarco busca usarlos como recurso para cumplir su objetivo: ejemplificar el carácter del protagonistade su Vida.
Radio Stations and Audience Communication: Social Media Utilization and Listeners Interaction
Authors: Pilitsidou Zacharenia , Tsigilis Nikolaos , Kalliris George
Published: June 2019

The purpose of the study was to explore how Greek radio stations utilize social media and Facebook in particular, and to look into factors that influence interaction with their audience. Twenty radio stations broadcasting from the two largest cities in Greece were selected according to their radio profile and number of followers. The duration of the study was two weeks, weekends included, with one month time lag between them. Results showed that the type of content seems to influence audience’s participation. Listeners had higher participation when they were reading information with content of their favourite radio broadcasting. Moreover, it was noticed that a specific time of the day might facilitate communication between radio stations and their listeners. Interaction patterns differ in relation to radio profile and radio stations broadcasting location. This paper represents a first attempt to investigate the ways Greek radio stations utilize social media to accomplish higher participation levels. An interaction index was introduced and used in order to better reflect radio station audience interaction. Given the relatively short observation period present these findings should be considered preliminary and exploratory. Longer data collection period combined with alternative social media such as Twitter, can provide a deeper understanding of the topic. Radio stations can utilize the present findings to develop a more effective strategy communication through social media.

Participación social en salud: ¿qué rumbo tomar en municipios de chiapas?
Authors: Trujillo Laura , Villafañe Sofía , García Néstor
Published: June 2019

Se parte de reconocer la ambigüedad teórica e ideológica del concepto Participación Social en Salud; asimismo el recrudecimiento de las adversas condiciones de vida y su impacto sobre la salud, particularmente en contextos de alta marginación en Chiapas, México. Con el objetivo de describir las características de participación de las mujeres en dos municipios de alta marginación, se aplicó una encuesta probabilística en 10 localidades de Oxchucy, San Lucas. Se usó un instrumento con preguntas abiertas y cerradas, aplicado mediante entrevista domiciliaria a mujeres (n =638). Se identificaron las posibilidades de intervención de las mujeres en la toma de decisiones relativas a salud; tanto en el espacio público como en el ámbito doméstico. La información procede de mujeres adultas, la mayoría se dice unida (87,5% y 82%, respectivamente) en San Lucas y Oxchuc, pero no todas viven con la pareja; tienen 5 hijos y 3,5 años de escolaridad, en promedio. La participación que las mujeres refieren tener en el espacio público es mínima, como asistentes sin derecho a voto en reuniones de las unidades médicas; en el ámbito privado únicamente las más jóvenes refieren compartir alguna vez la toma de decisiones sobre aspectos relacionados con la vida y salud propia y de los hijos/as. Se discuten las alternativas para superar la deficitaria participación de mujeres y hombres en la toma de decisiones que afectan a la vida comunitaria, que potencialmente contribuirían al mejoramiento de las condiciones de vida y salud de los  habitantes de municipios marginados en Chiapas.

La finitud y los límites del sufrimiento humano: una lectura de Amour de Michael Haneke
Authors: Caponi Sandra
Published: June 2019

Este escrito analiza la temática de la muerte digna a partir de la película de Michael Haneke, Amour. Tomando esa cintacomo eje articulador, se propone una reflexión crítica sobre el lugar que ocupa el sufrimiento y el dolor que antecede a la muerte en la sociedad contemporánea, valiéndose, para ello, de autores como Séneca en sus Cartas Morales a Lucilio, Norbert Elias en La soledad de los moribundos, y del último libro publicado por André Gorz, Carta a D. Este artículo pretende dar visibilidad a un tema que la sociedad contemporánea se obstina en ocultar, como es el sufrimiento que antecede a la muerte, y de subrayar la importancia que los lazos afectivos, en este caso el amor conyugal, pueden tener en ese proceso.

Nuevos trabajos, nuevos riesgos. Chile y los factores de riesgo psicosocial laboral
Authors: Pérez-Franco Juan
Published: June 2019

Los factores de riesgo psicosocial laboral (FRPSL) han cobrado una creciente importancia en el mundo dado que están relacionados con todo tipo de patologías, desde la cardiovascular hasta la mental. Este creciente interés no se debe tan solo a una preocupación actual de los organismos sanitarios internacionales, sino que a un cambio en la estructura del trabajo mismo. Este artículo analiza algunas estadísticas históricas y actuales del trabajo en Chile, en las que se evidencia el paso desde una estructura económica productiva hacia una estructura de servicios y comercial que trae nuevas exigencias para los trabajadores, mayor participación de la mujer, precariedad del empleo e interferencia del trabajo con la vida privada. Este cambio es el que está en la base de los nuevos riesgos en el trabajo. A los trabajadores hoy se les exige competencias cognitivas, emocionales, y una completa flexibilidad personal para adaptarse a las exigencias de los trabajos, lo que parece evidenciarse en la prevalencia de enfermedades profesionales mentales y musculoesqueléticas. En Chile existe un progresivo interés científico en la evaluación de este nuevo escenario, así como incipientes esfuerzos regulatorios por parte del Estado. Un desarrollo mayor en esta área solo será posible en la medida que se tome conciencia del cambio ocurrido en el trabajo y sus nuevos riesgos asociados.

Authors: Liu Siyu , Kondo Makiko
Published: June 2019

The purpose of this article is to explore the attitude of Intensive Care Unit (ICU) nurses of good death and to improve the quality of death of dying patients in ICU. The authors conducted a literature search from databases for published, English-language, peer-reviewed reports of qualitative studies that focused on attitude of ICU nurses of providing good death from different cultures during 2009-2018. 13 studies met eligibility criteria with the following two questions: A. “What are the obstacles to realize good death in ICU?” B. “How to help ICU dying patients to get good death?”. According to these questions, we grouped all results. Finally, 5 categories each answered Research Question A(RQ-A), and 5 indicated RQ-B. The following four factors that can promote the good death of ICU dying patients: 1) Legalizing and standardizing “good death” in ICU by providing education, physical and mental support for nurses; 2) Gaining trust of family and seeking consistency of important decisions; 3) Creating a physical and cooperative environment of ICU that benefits dying patients; 4) Giving priority to satisfy physical and mental needs of dying patients and their families, leaving no regrets.

Influence of Oryzanols Concentrate on the Oxidation of Methyl Ester Linoleic Acid and Study of Their Oxidation Products
Authors: Irigaray Bruno , Jachmanián Iván , Grompone María A.
Published: June 2019

Oryzanols are frequently found in rice bran oil but almost completely removed in the neutralization step when the oil is chemically refined. In this way, oryzanols can be recovered from the soapstocks to generate a concentrate. Thereby, they could be used as antioxidants in lipids for specific purposes. In the present work the antioxidant power of oryzanols concentrate (33% purity) was studied together with pure oryzanols and butylhydroxytoulene (BHT). Methyl esters were prepared from regular sunflower oil without antioxidants to which the antioxidants before mentioned were added in an effective concentration of 3x10-3 M. The samples were oxidized in a heating block with oxygen flow and the hydroperoxides of linoleic acid methyl ester were analyzed. It was observed that all antioxidants were able to protect the sunflower oil methyl esters from oxidation with respect to methyl esters without antioxidants. Oryzanols presented a notoriously lower protection ability compared to BHT. However, the formation of the linoleic acid methyl ester hydroperoxides and their proportion, for the same oxidation stage, did not show differences between the antioxidants used. Therefore, the oxidation kinetics were similar between the different antioxidants studied.
Sjögren's syndrom – the review of the latest diagnostic guidelines essential for otolaryngologists
Authors: Kruk Karolina , Rzepakowska Anna , Osuch-Wójcikiewicz Ewa , Niemczyk Kazimierz
Published: June 2019

Sjogren's syndrome (SS) is a complex connective tissue disease with autoimmune background and high clinical, radiological and molecular heterogeneity. SS is typically manifested by sicca syndrome, characterized by dry eyes and dry mouth due to autoimmune-induced inflammation of the lacrimal and salivary glands. Complications of sicca syndrome are dental caries, oral candidiasis, dysosmia, dysgeusia, difficulties in swallowing and chewing. SS may coexist with other diseases of rheumatoid and autoimmune etiology. SS is linked to a 16-fold increased risk of non-Hodgkin lymphoma. Early diagnosis results in inappropriate treatment and may slow down the course of the disease and limit extraglandular involvement. Due to diverse clinical phenotypes and symptomatology, establishing the diagnosis is often difficult. In 2016 the American-European Consensus Group (AECG) and European League Against Rheumatism (EULAR) proposed a classification system that defines SS as a systemic disease. Diagnostic tools in establishing SS diagnosis are serological tests, ultrasonography, Schirmer’s test, unstimulated whole saliva flow rate, and Ocular Staining Score. The complete curing of SS is still not possible. As a complex multisystem disease, SS requires multidisciplinary cooperation and individual diagnostic and therapeutic approaches in patients.
Therapy is focused on the treatment of symptoms and prophylaxis of complications. The laryngological treatment of oral cavity symptoms in SS includes supervision of proper oral hygiene habits and adequate fluids supplementation. The EULAR Sjögren's syndrome disease activity index (ESSDAI) and Clinical Oral Dryness Score(CODS) is used to monitor disease progression and treatment effectiveness.
Conceptualization of Negative Attitudes towards People with Schizophrenia in Turkey
Authors: Umucu Emre
Published: June 2019

Previous studies have shown that stigmatizing attitudes toward individuals with schizophrenia are common in Turkey, and Turkish society has a tendency to reject such individuals. The purpose of this paper, therefore, is to provide an overview of negative attitudes towards people with schizophrenia in Turkey. A systematic search of the literature in Academic Search Complete, CINAHL, ERIC, MEDLINE, and PsycINFO was performed to review these negative attitudes. Six major themes were identified in 32 studies: (a) health care providers’ negative attitudes, (b) family’s and caregivers’ negative attitudes, (c) the public’s negative attitudes, (d) students’ negative attitudes, (e) perceived and internalized stigma, and (f) stigma reduction. The results supported the hypothesis that health care providers, caregivers and families, the public and students have negative attitudes toward people with schizophrenia, which is consistent with the results of studies conducted worldwide.
The Association between Body Mass Index and Gender Role Stress Among Young Hungarian Males
Authors: Susánszky Anna , Döbrössy Bence
Published: June 2019

According to literature references, Body Mass Index (BMI), the quality of sexual life, sexual activity, and satisfaction with sexual life are closely associated. However, we found no research dealing with the relation of gender role stress to the above-mentioned factors in our review of the literature. That is why we chose to focus our research on the association of BMI and gender role stress of young Hungarian adult men. Our data is from the ‘Hungarostudy 2013’ (SUSÁNSZKY & SZÉKELY 2013) national representative survey (N = 2000) of which 298 18–35-year-old men belonged to the subsample researched. Besides socio-demographic data, we used data on height, weight, selfrated health status, the WHO (World Health Organization) Well-Being Index, the Illness Intrusiveness Rating Scale and the short form of Beck Depression Inventory. The Male Gender Role Stress Scale (MGRS) was used to measure gender role stress. Our results demonstrate that overweight and obesity play a significant role in the development of gender role stress. Young overweight and obese men in our sample were much more likely to report high gender role stress (OR = 1.67) and within this, sexual performance related stress (OR = 1.76) and sexual arousal related stress (OR = 3.15) than men with normal BMI.As our research was aimed at investigating social expectations measurable in terms of gender role stress and not with real sexual dysfunctions per se, our results indicate that even male gender role expectations, more precisely, sexual performance related expectations, may cause considerable stress for overweight/obese men.
A influência das ações de inclusão nos processos de resiliência de alunos da Educação Especial
Authors: Yanaga Thais Watakabe , Coimbra Renata Maria
Published: June 2019

Este estudo teve como objetivo analisar como as ações de inclusão se articulam com processos de resiliência em adolescentes e jovens da Educação Especial, a partir da perspectiva dos alunos. O referencial teórico adotado se refere à abordagem socioecológica, cujos pressupostos dos estudos da resiliência se pautam, principalmente, numa abordagem cultural. Com relação à temática da inclusão, é entendida neste trabalho como um processo que valoriza as diferenças. A pesquisa de abordagem qualitativa foi realizada por meio de estudo de caso, que consistiu em pesquisa de campo, mais precisamente num estudo de caso múltiplo, que se realizou em seis campi do IFPR. Buscou-se analisar a percepção dos alunos considerados em processo de resiliência sobre as ações de inclusão desenvolvidas no IFPR, como contribuindo para o processo de inclusão e para o bom crescimento dos alunos. Participaram deste estudo 12 alunos considerados em processo de resiliência. A partir das ações de inclusão citadas pelos alunos, por meio das entrevistas e das fotos, estas foram analisadas à luz das sete tensões da abordagem socioecológica, verificando por meio de suas resoluções ou não, o favorecimento de processos de resiliência. Os resultados apontaram que poucas ações de inclusão eram desenvolvidas institucionalmente, pois a maioria das ações era realizada por iniciativa própria dos professores e da equipe pedagógica. Porém, por meio dessas ações, a maioria dos alunos da Educação Especial se sentiam incluídos, indicando que tais ações estavam favorecendo processos de resiliência, atuando como ações protetivas.

Published: June 2019

Orientado teórica e metodologicamente pela perspectiva histórico-cultural, objetivou-se neste estudo desvelar indícios do processo de transformação de um aluno com Transtorno do Espectro Autista (TEA) e seu professor, focalizando a dinâmica dialógica entre eles. Buscou-se investigar como, por meio de palavras, gestos e ações, aluno e professor vão dando novos sentidos às atividades pedagógicas no contexto da escola de educação especial. Os dados da pesquisa foram construídos por meio de filmagens, com posterior transcrição; a análise, de cunho microgenético, buscou indícios dos fenômenos em estudo e contribuiu para a reflexão sobre os modos de atuação dos participantes que, juntos, foram (re)significando os acontecimentos em curso. Por intermédio de um trabalho educacional orientado pela perspectiva Histórico Cultural, palavra do outro e por novos modos de atribuição de sentidos aos déficits decorrentes dos fatores biopsicossociais que envolvem a condição de TEA, constataram-se possibilidades de transformação dos estereótipos que historicamente constituem esses sujeitos.
Desafios e possibilidades da inclusão escolar de crianças com a Síndrome Congênita do Vírus Zika: o olhar docente
Authors: Batista Gessivânia De Moura , Moutinho Ana Karina
Published: June 2019

A Síndrome Congênita do Vírus Zika (SCVZ), acometeu, entre 2015 e 2018, 3226 crianças em todo Brasil. Estas crianças, nasceram com um padrão de múltiplas deficiências, incluindo déficits visuais, auditivos, motores e cognitivos. Passados três anos desde o início da epidemia, acentua-se a necessidade de discutir sobre sua inclusão escolar, uma vez que, em virtude dos agravos ocasionados pela Síndrome, o suporte social e educacional especializado é imprescindível. O objetivo do presente estudo é apresentar os resultados de uma investigação acerca dos desafios e possibilidades da docência à crianças com a SCVZ, sob a ótica de duas professoras atuantes na Educação Infantil da rede pública de ensino de Pernambuco. Utilizamos como instrumento de investigação um total de cinco entrevistas semiestruturadas. Os resultados obtidos neste estudo apontam que os principais fatores que dificultam a inclusão de crianças com a SCVZ, reconhecidos pelas docentes são: as más condições na estrutura física da escola; e a falta de conhecimento das especificidades da Síndrome. Porém, ao longo da pesquisa, quando continuavam a prospectar sobre o futuro, as profissionais consideram que diante da situação de lecionar para crianças com a SCVZ, promoveriam situações de inclusão, a partir do uso de materiais concretos, coloridos e de texturas. Diante dos resultados obtidos, concluímos que as professoras imaginam desafios, e até possibilidades para que docência a crianças com a SCVZ seja exitosa, porém por falta de preparo técnico sobre a Síndrome, não conseguem traçar possibilidades de ação mais direcionadas a estimulação multissensorial, cognitiva, motora e socioafetiva desses discentes.

O presente trabalho teve como objetivo analisar variações sazonais na composição das comunidades do bacterioplâncton e arqueoplâncton, durante três anos consecutivos, e avaliar as possíveis influências de variáveis limnológicas e de fatores climáticos sobre as comunidades procarióticas na coluna de água da Barragem Armando Ribeiro Gonçalves. PCR (Reação da Polimerase em Cadeia) e DGGE (Eletroforese em gel com gradiente de desnaturação) foram usadas para analisar as composições das comunidades procarióticas heterotróficas do reservatório influenciado por períodos alternados de chuva e estiagem. A abundância do bacterioplâncton e arqueoplâncton e a riqueza dos amplicons da DGGE foram mais influenciadas pela pluviosidade, pela temperatura da água e pela concentração de fósforo total. A análise de componentes principais (PCA) mostrou fortes correlações entre estes fatores. A análise de correspondência canônica (CCA) revelou diferenças temporais na composição das comunidades de Bacteria e Archaea relacionadas à pluviosidade, ao volume do reservatório, à temperatura e à densidade de bactérias e arqueas, indicando a predominância dos fatores ligados aos eventos de precipitação com influência significativa sobre estrutura dessas comunidades, possivelmente compostas por populações permanentes e populações transitórias que influenciam a qualidade ambiental. O destaque da ocorrência de Archaea no reservatório abre uma nova possibilidade de investigação para futuros estudos sobre as intereações das comunidades microbianas e as consequências das suas atividades.

Este estudo investiga percepções e crenças relacionadas à fauna cinegética na comunidade Cruz, no município de Delmiro Gouveia, Estado de Alagoas. As informações foram obtidas por meio de entrevistas semiestruturadas e conversas informais realizadas com 17 moradores no período de maio a dezembro de 2016. Segundo a percepção dos entrevistados, as espécies cinegéticas mais abundantes são gambá (n=12), rolinha (n=10) e mocó (n=6). A respeito da fauna silvestre que se tem tornado rara na região, os entrevistados citaram tatu (n=10), tamanduá (n=4), seriema (n=4) e porco-do-mato (n=4). As representações da fauna cinegética na comunidade Cruz se caracterizam por mitos, crenças, saberes e tabus alimentares, que constituem práticas culturais e ecológicas relevantes, uma vez que as crenças associadas aos animais disciplinam a prática de caça e são importantes estratégias para uso sustentável dos recursos faunísticos.

Background: CT scan is an imaging device that is widely available and is very sensitive to different causes of abdominal pain. The aim of this study was to evaluate the CT scan results role of patients with abdominal pain in diagnosis and future decisions on patient and comparison with patient’s history and physical examination. Methods: In this descriptive analytical study, 215 patients admitted to the emergency room at Imam Reza Teaching Hospital with non-traumatic abdominal pain were studied over the years regarding the comparison of CT findings with the history, physical examination, plain radiography and ultrasound. Demographic characteristics, patient history, symptoms at the first visit, clinical findings, laboratory tests, imaging findings, diagnosis and treatment of all patients were collected. Results: CT scan to confirm the diagnosis or screening patients with abdominal pain has been helpful. The results of 215 CT scan 28.40% was normal, most frequently diagnosis in CT scans was related to pancreatitis 24% and least diagnostic of CT scans related to ileus. Of 215 patients, plain abdominal radiography was requested in 78 patients (36.3%) that the air-fluid level was reported in 18 cases (23.7%). Of 215 patients, abdominal ultrasonography was performed in 117 patients (54.4%) that the most recognizable diagnosis was cholelitiasis in 22 cases (18.8%) an abdominal ultrasound result was normal in 98 cases (83.7%). Finally of the 215 patients, 116 patients (77.2%) admitted and 49 patients (22.7%) were discharged. Of 166 patients, 51 patients (30.72%) were transferred directly from the emergency department to the operating room. Conclusion: CT scan play a decisive role in the decision to hospitalize patients and request in right place expedite the handling patients. Our study suggests the balance between the amount of requested CT in patients with non-traumatic abdominal pain and hospitalization rate.

Background: Hospital-associated infections are related with mortality, extended hospital stay, morbidity and attributable costs to the health care sector. The main objective of this study is measuring infected patients’ knowledge on infection control precaution in University Malaya Medical Center. Methods: Survey of 184 infected patients admitted to University Malaya Medical Center (UMMC) in Malaysia determined infected patients’ knowledge level regarding infections control activities. Results: Infected patient’s knowledge on infection control precaution in given medical center (UMMC) is moderately high with 65.2% good knowledge among infectious patients. Nevertheless, certain knowledge areas of infection control need to improve –i.e., transferring infected patients to isolation room immediately and using facemasks by medical staff while attending patients. The age, level of education of patients and the source of receiving information regarding to controlling infection cannot influence infected patient’s knowledge of infection Control. While the gender of patients, patients’ job experience in healthcare environment, relatives of patients’ job experience in healthcare environment, frequency of hospitals admission and the received information related to controlling infection can influence infected patient’s knowledge of infection Control. Conclusions: Actions intended at improving knowledge are essential to the implementation and development of efficient public health preventative strategies.
The Therapeutic Potential of Resveratrol in Gliomas
Authors: Richard Seidu A.
Published: June 2019

Resveratrol (RSV) is found in most human foods especially fruits such as grapes, peanuts, strawberry, blueberry, cranberry, mulberry, lingberry, sparkleberry, bilberry and in flowers as well as leaves like butterfly orchid tree, eucalyptus, spruce, lily, gnetum and so many others. Functionally, RSV has the propensity to safeguard DNA as well as the induction of DNA repair. RSV is precipitously metabolized in the liver via phase-II detoxification enzymes leading to its principal urine excretion. RSV steered growth inhibition, induction of apoptosis and G0/G1-phase cell cycle arrest in an experiment involving glioma cells. RVS can block the triggering of signal transducer and activator of transcription (STAT3) signaling of glioma cells. RSV subdues STAT3 signaling via the inhibition of SRC or Janus kinase (JAK2) induction, thereby inducing growth inhibitory and apoptotic properties. RSV explicitly blocks both COX-1 and COX-2 in-vitro. In the cancer inflammatory milieu, the blockade effects of RSV on NF-κB could also lead to the blockade of TNF-α resulting in inhibition of cancer advancement as well as metastasis. Individually, RSV has proven to very potent in glioma cells. It is able to down-regulate glioma angiogenesis as well as metastasis. In combination with other agents, RVS augment its potency in glioma. RVS is able to cross the blood brain barrier (BBB) via gap junctions making it very efficient central nervous system medication. RVS after oral administration peaks in the blood stream after one hour meaning it acts very fast. This review focuses on the neuropharmacological role of RVS in glioma.
