Pengaruh Lama Penyimpanan terhadap Aktivitas Antioksidan Berbagai Macam Jus Buah Berdasarkan Metode DPPH
Authors: Hartono Budiman , Chrisanto Chrisanto , Farfar Inggrid Osya 
Published: April 2020

Radikal bebas adalah suatu senyawa oksigen yang bersifat tidak stabil karena memliki elektron bebas yang tidak berpasangan, sehingga jumlah elektronnya ganjil. Karena sifatnya yang tidak stabil maka radikal bebas selalu berusaha mencari pasangan elektron baru dengan cara mengambil elektron molekul lain yang berdekatan. Radikal bebas yang terlalu banyak dapat menyebabkan stress oksidatif sel. Antioksidan merupakan senyawa yang mampu menghambat atau mencegah kerusakan akibat oksidasi dari senyawa radikal bebas. Tubuh dapat menciptakan antioksidan alami seperti enzim gluthatione, catalase dan superoxydedismutase. Namun karena pembentukan antioksidan alami tidak sebanding maka dibutuhkan asupan antioksidan yang lebih banyak lagi. Penelitian ini dilakukan untuk mengetahui bagaimana pengaruh lama penyimpanan terhadap aktivitas antioksidan dalam 4 macam jus buah. Pada penelitian kali ini 4 macam buah yang digunakan yaitu ; buah stroberi, jeruk, pisang dan alpukat. Radikal bebas yang biasa digunakan pada sampel pada penelitian antioksidan adalah 1,1-difenil-2-pikrilhidrazil (DPPH). Metode DPPH sering digunakan karena sederhana , cepat dan mudah untuk skrining aktivitas penangkap senyawa radikal bebas. Parameter untuk menginterpretasikan hasil pengujian DPPH adalah IC50 (inhibition concentration). Hasil penelitian menunjukkan IC50 buah stroberi sebesar 31.45 ppm, IC50 buah jeruk sebesar 58.01 ppm, IC50 buah alpukat sebesar 78.83 ppm dan IC50 buah pisang sebesar 92.99 ppm. Penelitian ini menggunakan analisis statistik One Way Anova dan mendapatkan hasil p= 0.992, dikarenakan p > 0.05 maka hasil ini menunjukkan tidak ada perbedaan yang bermakna antara lama penyimpanan terhadap nilai IC50 dari hari ke 1 sampai ke 4. Dapat disimpulkan bahwa lama waktu penyimpanan tidak berpengaruh secara bermakna terhadap nilai IC50 setiap buah.

Authors: Tezel Nihal , Gültuna Selcan 
Published: April 2020

Objective: To evaluate the basophil lymphocyte ratio (BLR) and eosinophil lymphocyte ratio (ELR) values in FMS that previously reported being used as an indicator of inflammation in autoimmune rheumatic diseases and smokers.
Material and Methods: We retrospectively analyzed 4500 FM patients who were registered in the network system with the M79-ICD code and 2000 healthy controls. A total of 216 FM patients and 194 healthy controls were included in the study.
Results: The blood BLR levels were significantly higher in FM patients than in healthy controls. (p< 0,02)The two groups did not show significant differences in terms of the other parameters (p> 0.05).
Conclusion: In the present study, neutrophil lymphocyte ratio (NLR), monocyte lymphocyte ratio (MLR), platelet lymphocyte ratio (PLR), ELR, platelet distribution width (PDW) are independent markers for early diagnosis and for the inflammatory predictive process. BLO levels were low revealed. To use these rates as disease markers should be supported by large-scale studies.

Physical activity and consumption of salty foods are some of the factors associated with the incidence of hypertension. People who consume a lot of salty foods and have less physical activity will be at greater risk of being affected by hypertension. This study aimed to find a physical activity, consumption of salty foods and the incidence of hypertension based on sociocultural coastal communities in Medan in 2019. This study used a cross-sectional study approach. The subjects in this study were 90 people in Belawan II Village. The instrument used was the basic health Research questionnaire. This study presents data on frequency distribution and cross-tabulation between physical activity and food consumption with hypertension. The results showed that the majority of subjects in this study had hypertension were adults (25-59 years) as many as 66 people, research subjects doing moderate physical activity as many as 67 people, consuming salty foods often (?1 time a day) as many as 40 people. Most of the subjects in this study who had hypertension rarely ate salty foods and undertook moderate physical activity (20.9%). It is expected that Belawan coastal communities will adopt a healthy lifestyle by reducing the consumption of salty foods and often doing physical activities in a day. Puskesmas staff is also expected to routinely check blood pressure levels and often give education about hypertension in the coastal communities of Medan City.
Luft sehen, sprechen, schützen
Authors: Landau Friederike , Toland Alexandra 
Published: April 2020

Der Beitrag verbindet die Diskussion um die postpolitische Stadt mit der zunehmenden wissenschaftlichen und aktivistischen Auseinandersetzung mit dem Anthropozän, ein Konzept, das die ökologischen und sozialpolitischen Implikationen menschlichen Handelns auf die Erdoberfläche beschreibt. Anhand von drei ausgewählten Fallstudien erkunden wir, wie die spezifisch anthropogene, also menschengemachte, Krise urbaner Luftverschmutzung in künstlerischen Positionen problematisiert wird. Im Kontext des potenziellen Vormarschs von Postpolitik besprechen wir, wie der ambivalente Diskurs des Anthropozäns einerseits Depolitisierung begünstigt und andererseits neue Möglichkeiten für die Repolitisierung globaler Umweltherausforderungen ermöglicht.
Erstens zeigen wir anhand von Amy Balkins Projekt „Public Smog“ (USA), wie künstlerischer Aktivismus nicht nur internationale Luftemissionshandelsregimes subvertieren kann, sondern durch das Aktivieren von Vorstellungskraft für bessere Luft affektive Utopien erschaffen kann. Zweitens beleuchten wir die Performance „Project Dust“ des chinesischen Künstlers Nut Brother, der selbstgesammelte Smogpartikel zu einem Backstein goss und Luftverschmutzung damit gleichzeitig als harte Tatsache und Anlass zur Sorge vermittelt. Drittens diskutieren wir den teils kommerziellen Ansatz des niederländischen Konzeptkünstlers und Designers Daan Roosegaarde, der mit seiner „Smog-Free“-Produktreihe innovative Lösungen für das Problem anthropogener Luftverschmutzung bereitzustellen versucht. Die künstlerischen Projekte umreißen die Streitbarkeit des öffentlichen Gutes Luft und fordern mit affektiven Mitteln zur Politisierung der postpolitischen, luftverschmutzten Stadt auf.
As homenagens do cientista paraense Guilherme de La Penha à Leonhard Euler
Authors: Chaquiam Miguel , Mendes Iran Abreu 
Published: April 2020

Apresentamos resultados de uma pesquisa qualitativa assentada em base documental definida a partir das indicações constantes no trabalho de Chaquiam (2012), especificamente quando retrata “os estudos de La Penha sobre a obra de Leonhard Euler”, onde foram investigadas fontes primárias sem a preocupação de quantificar dados ou provar hipóteses estabelecidas a priori. Respondemos ao questionamento “Quais estudos foram desenvolvidos por Guilherme de La Penha sobre Leonhard Euler?” uma vez que o objetivo principal “Apresentar os preitos de Guilherme de La Penha à Leonhard Euler” foi atingido a partir do momento que retratamos passos de Guilherme Maurício Souza Marcos de La Penha, permeados com traços biográficos, formação acadêmica, atuação profissional e produção intelectual desse multifacetado cientista paraense, que é considerado por alguns como excelente gerador e gerenciador da ciência no Brasil. Guiados por Chaquiam (2012), foram elencados os trabalhos elaborados no período de 1983 a 1986, que tem como foco principal o matemático suíço Leonhard Euler. Os trabalhos identificados evidenciam que La Penha conhecia bem as obras desse eminente matemático, sobretudo pela forma abrangente e profunda que retrata o legado de Euler. Ressaltamos os trabalhos encaminhados à Embaixada da Suíça no Brasil, escritos ao longo do ano de 1983, ano de homenagens a Euler em decorrência do seu bicentenário de morte. Por fim, é possível constatar que Euler foi para La Penha um pensador original e sintético, que exibe um espírito de inquisição crítica e liderança, embora tratado, em certos momentos, de forma romântica.

Published: April 2020

ABSTRACTThe use of digital technologies in education is providing a dialogic relationship between teachers and students by the fact that it constitutes itself as a means of relevant pedagogical possibilities that make the most dynamic teaching. The emergence of homo zappiens generation reveals that the school as an institution is not yet fully ready to meet this new generation born amid the technology and is present in the educational system. In this regard, the Virtual Learning Environment (VLE) emerges as a tool in order to improve the quality of education through Information and Communication Technologies (ICT), which allows the student to a higher performance in learning and places the school environment in their daily lives. The objective of this work is to research on the contributions of a VLE for teaching Biology with students from first grade of secondary education at a private school in the city of João Pessoa, Paraíba, Brazil. The analysis of VLE contributions showed that the use of digital technology presents itself as an appropriate tool for teaching content that requires a greater commitment of time, contributing to the formation and strengthening of critical thinking, evaluation and autonomous of the studentRESUMOA utilização das tecnologias digitais na educação vem proporcionando uma relação dialógica entre professores e alunos pelo fato da mesma constituir-se como um meio de relevantes possibilidades pedagógicas que tornam o ensino mais dinâmico. O surgimento da geração homo zappiens, nos revela que a escola como instituição ainda não está inteiramente pronta para atender a essa nova geração que nasceu em meio à tecnologia e está presente no sistema educacional. A este respeito, o Ambiente Virtual de Aprendizagem (AVA) surge como uma ferramenta no intuito de melhorar a qualidade do ensino através das Tecnologias da Informação e Comunicação (TIC), o que possibilita ao aluno um maior desempenho na aprendizagem e insere o ambiente escolar no seu cotidiano. O objetivo deste trabalho é pesquisar sobre as contribuições de um AVA para o ensino de Biologia com estudantes da primeira série do ensino secundário de uma escola privada na cidade de João Pessoa, Paraíba, Brasil. A análise das contribuições do AVA mostrou que a utilização da tecnologia digital apresenta-se como uma ferramenta apropriada para o ensino de conteúdos que requerem uma maior dedicação de tempo, contribuindo para a formação e aprofundamento do pensamento crítico, avaliativo e autônomo do discente.

ABSTRACTThis work is part of a larger study investigating the influence of Brazilian educational public policy in the preparation of textbooks Citizen Chemistry, from a higher education project. The objective of this study is to identify what changes observed in the preparation of editions of didactic work approved by the National Textbook Program (PNLD) by preestablished aspects in the evaluation sheets and Notices selection. The analyzed textbooks were approved on selections made by PNLD for the 2007 academic years, 2012 and 2015 to the curricular component chemistry in high school. With the qualitative research option in its development, this work makes use of bibliographic data available in official Notices and teaching guides forwarded to teachers of Brazilian public schools, and the characterization of the didactic work Citizen Chemistry, uses the interpretation of images and texts, as subcategories established. This is different situations similarity between its different editions, where the didactic work analyzed turns out to "say the same thing or nearly so" (Valen you cited Chervel, 1990, p.203), in its various editions, or also called by the authors of Vulgate, due to obvious similarity between the books.RESUMOEste trabalho faz parte de um estudo mais amplo que investiga a influência da política pública educacional brasileira na elaboração do livro didático Química Cidadã, oriundo de um projeto do ensino superior.

ABSTRACTNowadays lacks in environmental education were detected even living in times of global change. In this research, the acquisition of knowledge related to environmental consciousness in secondary school students in northeast Spain is examined. A questionnaire for each secondary course was made with different kind of questions: specific of the course and of the previous knowledge. After a statistical analysis, with R programming language, a unilateral hypothesis contrast where the mean responses of the students answered correctly at the beginning and the end of the different courses of secondary education, were contrasted. After analysis, the results shows that the mean responses answered correctly at the end of the course is greater than the mean at the beginning of course in most cases studied, except two groups. The findings of this study indicate that the education of our students conclude with a meaningful learning as indicated but we should not neglect the non-formal education received by students in order to have people environmentally conscious.RESUMENActualmente se han detectado carencias en la educación ambiental aun estando viviendo momentos de cambio global. En el presente estudio de investigación, se examina la adquisición de los conocimientos relacionados con la concienciación ecológica en los alumnos de educación secundaria en el nordeste de España. Se realizó un cuestionario para cada curso con diferentes tipos de preguntas: específicas de curso y conocimientos previos. Tras un análisis estadístico, con el lenguaje y entorno de programación para análisis estadístico R, se realizó un contraste de medias unilateral donde se contrastó la media de respuestas respondidas correctamente de los alumnos de los diferentes cursos de educación secundaria, a final y a inicio de curso, de dicho cuestionario. Tras el análisis de los resultados se observa que la media de respuestas respondidas correctamente a final de curso es mayor que la media al inicio de curso en la mayoría de casos estudiados a excepción de dos grupos. Las conclusiones de este estudio indican que la educación que reciben nuestros alumnos concluye en un aprendizaje significativo tal y como se indica aunque no debemos descuidar la formación no formal que reciben los alumnos para así tener ciudadanos concienciados con el medio ambiente.

Un Hypertexto para la enseñanza de la Estadística No Paramétrica: Propuesta didáctica para el proceso de enseñanza-aprendizaje de las Ciencias Sociales / A Hypertext for the Teaching of Nonparametric Statistics: Didactic Proffer for the Teaching-Learning Process of the Social Sciences
Authors: Gonzalez Romero Alicia 
Published: April 2020

ABSTRACTA hypertext was realized as a didactic guide to construct and explain the different hypothesis tests related with nonparametric statistics by using the Raimon Duvals semiotic theoretical base, the learning based on Donald Shon´s problems, and exercises of social kind. Microsoft Excel was used as didactic software , the tests were developed according to the constructivism. There was an explanation consistent in an hypothesis test beginning with thw the binomial development and it was continued with exercises analysis and development of the hypothesis tests exercises included in the nonparametric statistics program. Working with a hypertext and the Excel software allowed to save capture time and numeric calculations. The indicators used to measure the learning, coincide in the display that shows that working with the hypertext favors the nonparametric statistics learning task. Nevertheless, the students recommended to add more theory in order to explain each topic and to add more exercises, with this we can conclude that the method is perfectible.RESUMENSe realizó un Hypertexto, como guía didáctica para construir y explicar las diferentes pruebas de hipótesis relacionadas con la Estadística no Paramétrica, con el sustento teórico de los Registros semióticos de Raimond Duval, el aprendizaje basado en problemas de Donald Shon y ejercicios de corte social, Se utilizó el programa Microsoft Excel como sosftware didáctico, se desarrollaron las pruebas de acuerdo con el constructivismo, se explicó en que consiste una prueba de hipótesis partiendo del desarrollo de la binomial y se continuó con el análisis y desarrollo de ejercicios de las pruebas de hipótesis contenidas en el programa de Estadística no Parametrica. El trabajar con un hipertexto, y el programa Excel, permitió ahorrar tiempo de captura y cálculos numéricos. Los indicadores utilizados para medir el aprendizaje, coinciden al mostrar que trabajar con el Hypertexto favorece el aprendizaje de la Estadística no Paramétrica, Sin embargo, los estudiantes recomendaron, agregar más teoría para explicar cada tema y añadir más ejercicios, con lo que se concluye que el método es perfectible.

Authors: Urbano Ruiz Sergio , Fernández Bravo José Antonio , Fernández Palop Pilar 
Published: April 2020

ABSTRACTOne of the biggest difficulties that Primary students face in Mathematics is problem solving. A strategy known as The Bar Model was developed in Singapore in the 1980’s. Its three variables (The Part-Whole Model, The Comparison Model and The Before-and-After Model) grant The Bar Model the possibility of being applied to a wide range of formulation problems. Besides, it paves the way for the student to assimilate algebra in an easier and more natural way in later educational stages. This paper shows the three Bar Model variables and several examples of its use.RESUMENUna de las mayores dificultades a que se enfrentan los alumnos de Primaria en Matemáticas es la resolución de problemas. En Singapur se desarrolló en los años 80 una estrategia conocida como Modelo de Barras. Sus tres variantes, el modelo Todo-Parte, el modelo de Comparación y el modelo Antes-Después otorgan al Modelo de Barras la posibilidad de ser aplicados en un amplio espectro de problemas de enunciado. Además, prepara el camino para que el alumno sea capaz de asimilar con más facilidad y naturalidad el álgebra en etapas educativas posteriores. En este trabajo se muestran las tres variantes del Modelo de Barras con varios ejemplos de aplicación. Contacto principal: sergio.urbano.ds@gmail.com
