GIRL’S EDUCATION IN TURKEY: AN ANALYSIS OF EDUCATION POLICIES FROM A FEMINIST PERSPECTIVE
Authors: Çöker Berna 
Published: August 2020

<p>In this study, I aim to provide an analysis of gender equality in the Turkish education system by looking at policies and their outcomes on girl’s schooling. My goal is to demonstrate the ways educational policies have been complicit in reproducing inequality and difference between the sexes by examining what issues regarding education and gender have become a part of public discourse, and which issues have not. The investigation of the role of the state in contributing to gendered outcomes in education is operationalized by two data gathering processes. The first is document analysis of policy documents which are the Article 42. Of the Constitution, Basic Law of National Education. Law 1739, and Basic Education Reform Act. No. 4306. The second is the collection of educational statistics and documents that would shed light to the condition of girls’ education in Turkey. The data draws on policies directly related to education to understand how gender equality is conceptualized. The central finding of the study is that the educational policies and practices in Turkey are based on the premises of “formal equality” and “meritocracy” which aims to provide the same opportunities to every member of society. However, the functional view of schooling based on the concepts of “formal equality” and “meritocracy” fosters the belief that males and females are benefitting equally and serve to mask the inequitable distribution of knowledge and skills between men and women. Therefore, educational policies continue to be gender-neutral, far from challenging the gender dynamics that discriminate against girls and women. Article 42. of the Constitution, the Basic Law of National Education. Law 1739., the Basic Education Reform Act. No. 4306 and its extension, 4+Reform, focuses on the expansion and improvement of primary and secondary education, but does not carry any special measures to change the structures and relations that discriminate against girls. No national policies to counter the impact of negative socialization by curriculum and textbook revision have been adopted. Moreover, high female attrition rates especially in the underdeveloped regions of Turkey continue to exist. Gender-streaming is still apparent in the program choices made in vocational and higher education. Turkey depends on macro education policies without any gender differentiation to ensure educational equality.</p><p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0661/a.php" alt="Hit counter" /></p>

<p class="SitioNovoResumo">A altitude de um local consiste na distância vertical entre determinado ponto na superfície terrestre e o nível médio dos mares, podendo ser determinada por diversos métodos. Devido ao uso crescente de novas tecnologias relacionadas ao Sistema de Navegação Global por Satélite (<em>Global Navigation Satellite System - GNSS</em>) na determinação da posição geográfica, inclusive para a determinação de altitudes, este trabalho tem como principal objetivo comparar dados obtidos através de nivelamento geométrico e de posicionamento em tempo real (<em>Real Time Kinematic - RTK</em>). O trabalho de campo foi realizado na cidade de Palmas – TO, onde para o levantamento executado pelo método RTK foram utilizados dois pares de receptores GNSS modelo Hiper II da fabricante Topcon, e para o nivelamento geométrico, foi utilizado um nível digital modelo Sprinter 250M da fabricante Leica Geosystems. Após o nivelamento e contranivelamento dos pontos, foi identificado erro altimétrico de 4 milímetros. Comparando-se os resultados obtidos, foi possível verificar que a média das diferenças entre as altitudes obtidas pelos dois métodos foi de 10 milímetros, sendo o desvio padrão dessas diferenças igual a 5 milímetros, caracterizando a amplitude amostral entre altitudes de apenas 21 milímetros. Deste modo, os resultados demonstram que a determinação da altitude pelo posicionamento em tempo real (RTK) apresentou precisão satisfatória atendendo adequadamente à maioria das necessidades da topografia, constatando-se rapidez e eficiência do método RTK também para determinação de desníveis.</p><p class="SitioNovoResumo"><strong>Palavras-chave</strong>: Altitude ortométrica.

Los mitos de la masculinidad y de la feminidad en El Señor de los cielos
Authors: Guzmán Nataly , Cristancho Andrea 
Published: August 2020

This article studies how a media product resulting from a combination between melodrama and action series establishes a number of features connected with gender identity in El Señor de los cielos, as well as the representations related to what it means to be a man or a woman. The gender narratives of this so called “super series” explore the relation between gender and nature versus the social construction of masculinity and femininity, the capacities associated with human agency, and the situations described as a result of destiny.

Acercamiento a la temática del amor
Authors: Barria-Asenjo Nicol A. 
Published: August 2020

The purpose of this work is to identify the different conceptions of love proposed by theorists of all times, concerning two unequal but complementary disciplines, psychoanalysis and philosophy. The paper researches the hypotheses of Freud and Lacan, succinctly in Plato in his work “The Banquet.” Likewise, contemporary theorists such as Žižek were analyzed. The article provides an approach based on a wide range of positions, the most widespread statements and also the most studied with respect to the human issue that has generated the most controversies: love. Finally, despite attempts to reach a more or less appropriate definition to define love ties, find a kind of norm, or the attempt to generalize, the contributions of philosophers and psychoanalysts, leave us with an advantageous panorama and the readings of the works grant us new elements, to address preliminary uncertain aspects of a very complex subject.

Prediction on the Mechanical and Forming Behaviors of Ferrite-Martensite Dual Phase Steels Based on a Flow Model
Authors: GOU Rui-bin , DAN Wen-jiao , ZHANG Wei-gang , YU Min 
Published: August 2020

An innovative flow model incorporating the mixture hardening law, anisotropic yield function, and incremental strain formulations was elaborated and applied to DP590 ferrite-martensite dual phase steel. To verify the flow model, both the macro/micro stress-strain responses and the forming patterns of DP590 steel with different martentite contents were simulated during the processes of the cup deep-drawing and the unconstrained cylindrical bending to evaluate the influence of martensite content on the mechanical and forming behavior of the steel. It was found that maternsite content has a significant impact on the macro/micromechanical and forming behavior of the steel, i.e., the ferrite and steel effective stresses and the effective macro/micro-strain distribution in the cup. Under the unconstrained cylindrical bending, the simulated effective maximum macro/micro-strains were in good agreement with the calculated results from the mixture law-based model. It was concluded that the Buaschinger effect is the main reason for an 8 % error between the simulated and experimental results. The flow model was proved to predict the macro/micro flow and forming behavior of the dual phase steels with a good accuracy.
Composite Membranes of Sulfonated Poly(ether ether ketone) with Active Carbon: Composite Preparation and Investigation of their Properties for Potential Application for CO2 Electrochemical Reduction
Authors: FEDORENKO Deniss , VAIVARS Guntars 
Published: August 2020

In this study, synthesis of sulfonated poly(ether ether ketone) (SPEEK) was performed using sulfonation method with concentrated sulfuric acid. Polymer with three degrees of sulfonation was obtained: 0.87; 0.82 and 0.74. Composite membranes were synthesized with an activated carbon. Ultrasonication method was used in order to achieve homogeneity of distribution of the additive in polymer solution and then in polymer membranes. Membranes with various content of the additive were made: 0; 0.15; 0.3; 0.5; 0.6; 0.8; 1.0; 2.0 and 3.0 %. Swelling degree, water uptake, proton conductivity, isoelectric point, thermal properties and surface morphology of the membranes were analyzed. Proton conductivity was determined using impedance analysis with two electrode system and through-plane configuration. Two methods were used: differential and single membrane method. Differential method is proposed to have significant advantage as it reduces contact resistance, which otherwise is difficult to control and evaluate. Surface zeta potential of membrane surface was investigated, and membranes have shown variation of the potential. Isoelectric point was determined for the membranes with DS 0.82 and carbon content 0 % and 0.5 %, and it was found to be at pH 4. Water uptake and swelling degree of the membranes was studied, and active carbon content was found to not have major influence on those properties, but higher content of sulfonic groups leads to increased water uptake and swelling degree. Thermogravimetric analysis showed slightly better thermal properties of membranes with the additive, compared to the blank membranes, which can be related to differences in the water uptake. Surface of the membrane was investigated using scanning electron microscopy, and no considerable defects were observed.
Usage of Fusible Sewing Threads to Improve the Waterproof Property of Seam
Authors: MESEGUL Cansu , KARABAY Gulseren 
Published: August 2020

In classical stitching process, needle holes occur during the penetration of the needle through the fabric. If the waterproofness of the sewn product is important, the water leakage from these holes must be prevented. To prevent this negative situation, different techniques such as sealing of seams with waterproof tapes, joining the textile materials by bonding or welding are used. Among these techniques, there is no needle damage in bonding and welding and all the seam area is covered by thermal or chemical bonding. In sewing technology, the water leakage is prevented by covering all the seam area with seam sealing tape. These three methods have different effects on the physical properties of the seams obtained. Instead of covering the whole seam area, covering just the needle damages is the focus of this research. With this aim, fusible sewing threads were used to cover the needle damages to increase the waterproof performance of seam line. The fusible sewing threads have not been used for obtaining waterproof seams before. In this research, the fusible sewing threads were used as lower thread in different combinations. Initial results of waterproofness test show that, melted fusible threads improve the waterproof performance of seams. In other words, the needle damages on sewn fabric can be covered by melted fusible sewing thread. However, unbalanced seam is the negative side of this research because of using different threads as needle and bobbin thread. Additionally, there is no variety of fusible threads to select an appropriate one for this method. The study is hoped to be a sample for the further studies on this method, using different fusible threads, fabrics, seam types and even improving new fusible threads for this waterproofing method.

RESUMEN El estudio del bienestar en el entorno educativo se ha replanteado con la inserción de elementos de la psicología positiva en el entorno escolar, misma que ha modificado algunas perspectivas en torno a la orientación educativa, en particular en la orientación vocacional. El sentido de bienestar ya no es un referente exclusivo del contexto de salud, contempla también las emociones, las relaciones sociales, el sentido de vida y logros personales, todos estos elementos se tornan necesarios a considerar en el currículo escolar. A esto se suma, que actualmente se conoce más sobre las características de los adolescentes que son parte de la generación de aprendices digitales. Por tanto, el reto en los proyectos de orientación educativa es consolidar cambios estructurales necesarios para orientar de la mejor manera posible a jóvenes. A ellos, en pocos años les tocará diseñar y elegir un proyecto de vida en un mundo que ofrece cada vez más opciones de formación profesional y en diversos formatos. Este trabajo propone un análisis de perspectivas y enfoques que abordan estos temas desde diferentes vertientes y plantea la necesidad de conjuntar visiones en enfoques propositivos e innovadores para atender las demandas de los jóvenes con la inclusión del sentido de bienestar en dichas propuestas de orientación.ABSTRACT The study of well-being in the educational environment has been reconsidered with the inclusion of elements of positive psychology in the school environment. This situation has modified some perspectives regarding educational guidance, particularly in vocational guidance. The sense of well-being is no longer an exclusive reference of the health context, it also includes emotions, social relations, the meaning of life and personal goals and achievements, all these elements are necessary to consider at the school curriculum. Additionally, more has been learned of the adolescents who belong to the digital-learner generation. Therefore, the challenge in educational projects is to consolidate structural changes necessary to guide young people in the best way possible. In the next years they will have to design and make decisions about a life project in a world that offers more and more options for professional training in different formats. This paper proposes an analysis of perspectives and approaches that address these issues from different perspectives and raises the need to combine visions in proactive and innovative approaches at educational guidance projects to meet the demands of digital learners with the inclusion of the sense of well-being in these proposals.
Database limitations for studying the human gut microbiome
Authors: Dias Camila K , Starke Robert , Pylro Victor S. , Morais Daniel K. 
Published: August 2020

Background
In the last twenty years, new methodologies have made possible the gathering of large amounts of data concerning the genetic information and metabolic functions associated to the human gut microbiome. In spite of that, processing all this data available might not be the simplest of tasks, which could result in an excess of information awaiting proper annotation. This assessment intended on evaluating how well respected databases could describe a mock human gut microbiome.

Methods
In this work, we critically evaluate the output of the cross–reference between the Uniprot Knowledge Base (Uniprot KB) and the Kyoto Encyclopedia of Genes and Genomes Orthologs (KEGG Orthologs) or the evolutionary genealogy of genes: Non-supervised Orthologous groups (EggNOG) databases regarding a list of species that were previously found in the human gut microbiome.

Results
From a list which contemplates 131 species and 52 genera, 53 species and 40 genera had corresponding entries for KEGG Database and 82 species and 47 genera had corresponding entries for EggNOG Database. Moreover, we present the KEGG Orthologs (KOs) and EggNOG Orthologs (NOGs) entries associated to the search as their distribution over species and genera and lists of functions that appeared in many species or genera, the “core” functions of the human gut microbiome. We also present the relative abundance of KOs and NOGs throughout phyla and genera. Lastly, we expose a variance found between searches with different arguments on the database entries. Inferring functionality based on cross-referencing UniProt and KEGG or EggNOG can be lackluster due to the low number of annotated species in Uniprot and due to the lower number of functions affiliated to the majority of these species. Additionally, the EggNOG database showed greater performance for a cross-search with Uniprot about a mock human gut microbiome. Notwithstanding, efforts targeting cultivation, single-cell sequencing or the reconstruction of high-quality metagenome-assembled genomes (MAG) and their annotation are needed to allow the use of these databases for inferring functionality in human gut microbiome studies.
