Authors: Maciel Aníbal de Menezes , Rêgo Rogéria Gaudencio do , Carlos Erenildo João
Published: May 2017

Resumo A humanidade atravessa um período de intensas mudanças, tendo no uso abundante da imagem uma forma de registrar, expressar e promover os acontecimentos que caracterizam a contemporaneidade. No presente trabalho, temos como questão norteadora: qual o papel que exerce a imagem fotográfica no seu emprego em livros didáticos de Matemática? Utilizamos a abordagem qualitativa do tipo bibliográfica. Como resultado final, verificamos que a imagem fotográfica pode exercer as funções ilustrativa, comunicativa, decorativa e epistêmica em relação aos diversos conteúdos de Matemática, notadamente em Geometria, especialmente no de simetria. Quanto à função epistêmica, detectamos um percentual em torno de 65% das fotografias computadas capazes de mediar, expressar e comunicar elementos relativos ao conteúdo matemático trabalhado, levando-nos a concluir acerca da importância da inserção da imagem fotográfica em livros didáticos de Matemática, de uma maneira intencional e planejada, como forma de contribuir para o processo de ensino e aprendizagem dos conteúdos.

Authors: Amaral Júnior Josué Coelho do , Silva Luiza Caroline Ferreira , Moravia Weber Guadagnin
Published: May 2017

Resumo A adição de fibras ao concreto é uma prática que busca reduzir o surgimento de fissuras e suas respectivas aberturas. Diversos tipos de fibras são utilizadas com esse fim como, por exemplo, as fibras de aço e as fibras poliméricas. O presente trabalho tem como objetivo avaliar a influência da adição de fibras poliméricas nas propriedades mecânicas do concreto. Para isso foram realizados ensaios de resistência à compressão, módulo de elasticidade, resistência à tração na flexão e avaliada a tenacidade de corpos de prova confeccionados com concreto convencional (sem adição de fibras), concreto com adição de fibras de polipropileno e concreto com adição de fibras de polietileno de alto módulo. O comprimento das fibras poliméricas utilizadas é de 12 mm. Os resultados mostram que essas adições melhoram o desempenho do concreto para a resistência à tração e tenacidade, porém não causaram variações significativas na resistência à compressão e no módulo de elasticidade.
Insights into geogrid–soil interaction using a transparent granular soil
Authors: Bathurst R. J. , Ezzein F. M.
Published: May 2017

Geogrid pullout tests were carried out in a large pullout box filled with a transparent granular soil. Geogrid displacements and displacements of a dispersed layer of opaque particles located immediately above and below the plane of the geogrid were measured from image analysis of pictures taken through a window at the bottom of the box. Longitudinal displacements of an extensible biaxial polypropylene geogrid were converted to strains and strain rates and these values used in a rate-dependent load–strain model to calculate load along the entire length of the specimen and load transfer to the surrounding soil. Plots of load transfer, expressed as equivalent shear stress acting over the area between transverse members, against relative horizontal deformation between the geogrid inclusion and the surrounding soil were generated. These data show that for the combination of geogrid and granular soil used in this investigation, load transfer is largely due to shear between the soil particles trapped in the plane of the geogrid between transverse members, and the surrounding soil. This observation suggests that the results of direct shear box tests can be used to characterise the stiffness of the shear interface between the horizontal inclusion representing the geogrid, and the surrounding soil.
Synthesis of isohexide-di(ether-ene)s and ADMET polymerization

Published: May 2017

As fossil fuel reserves deplete and greenhouse gases increase, the scientific community is challenged to provide sustainable solutions. Sugar-based isohexides can be modified to prepare a library of isohexide-diene monomers for polymerization. Such isohexide-diene monomers can be subjected to acyclic diene metathesis (ADMET) polymerization to obtain green materials. This paper reports a single-step synthetic protocol to access a small family of isohexide-di(ether-ene)s and the corresponding polymers. The isohexide di(ether-ene)s could be isolated in good to excellent yields under optimized conditions. The resultant isohexide-di(ether-ene)s are potential versatile building blocks for pharmaceuticals and materials science. The synthetic utility of isohexide-di(ether-ene)s was demonstrated by subjecting them to ADMET polymerization using Grubbs first- and second-generation catalysts. The resultant viscous material was evaluated using proton nuclear magnetic resonance and matrix-assisted laser desorption/ionization time of flight mass spectroscopy, which suggest the formation of anticipated ADMET polymers. End-group analysis of the polymers revealed molecular weights of 800–13 800 g/mol. Slight improvement in the molecular weight was observed when benzoquinone was added or when the catalyst was added in two stages. Thus, the analysis of the poly(ether-ene)s suggests that low-molecular-weight polymers were formed under the optimized experimental conditions, and the molecular weight could not be improved beyond a point.
A new model for the electrical conductivity of cement-based material by considering pore size distribution
Authors: Liang Kun , Zeng Xiaohui , Zhou Xiaojun , Qu Fulin , Wang Ping
Published: May 2017

Electrical conductivity is one of the most important indicators of the durability, impermeability and frost resistance of cement-based materials (CBMs). It is also a main performance parameter for some special CBMs such as insulating concrete and electrically conductive concrete. The aim of this study was to examine the relationship between electrical conductivity and saturation degree of CBMs more deeply by considering the pore size distribution (PSD), which is described in a new way. The distribution of the pore solution (the main conducting medium) in CBMs was analysed by considering the PSD function, the Kelvin equation and theories of capillary and surface adsorption. According to the pore solution distribution and conductivity theory, a conducting tube network model was established. The curves obtained by the proposed model were found to fit the experimental data well. The conducting tube network model was then used to analyse the factors influencing the electrical conductivity of CBMs. The conclusions obtained from this study were that the electrical conductivity of CBMs varies with the relative ratio of large and small pores and the mean value and standard deviation of large pores, and that the electrical conductivity of CBMs is proportional to the pore solution conductivity and porosity of the CBM.
Axial strength of FRP-confined rectangular RC columns with different cross-sectional aspect ratios
Authors: Li Xian , Lu Jie , Ding Dei-Dou , Wang Wei
Published: May 2017

This paper aims to contribute to a better understanding of the axial behaviour of rectangular reinforced concrete (RC) columns with large cross-sectional aspect ratios (section depth to width ratios) confined by carbon-fibre-reinforced polymer (CFRP). Three series of rectangular RC columns with cross-sectional aspect ratios of 2·25, 2·0 and 1·8 were tested under monotonic uniaxial compressive loads until failure. The effects of aspect ratios and CFRP anchors on the confinement effectiveness of CFRP wraps for rectangular RC columns were evaluated. The test results indicate that CFRP wraps enhanced the compressive strength of CFRP-confined rectangular RC columns even with a large aspect ratio of 2·25; however, the strength enhancement levels decreased with an increase in aspect ratio. CFRP anchors were effective in restraining concrete from bulging out and thus improved the confinement effectiveness of the CFRP wraps. Based on the test results regarding medium- and large-scale CFRP-confined rectangular RC columns available in the literature and this study, some existing confinement models for rectangular RC columns were assessed and a new analytical model was developed through regression analysis of the database. The proposed analytical model was found to be in good agreement with the test results in the database.
Cell Therapy in Kidney Transplantation: Focus on Regulatory T Cells
Authors: Zwang Nicholas A. , Leventhal Joseph R.
Published: May 2017

Renal transplantation is the renal replacement modality of choice for suitable candidates with advanced CKD or ESRD. Prevention of rejection, however, requires treatment with nonspecific pharmacologic immunosuppressants that carry both systemic and nephrologic toxicities. Use of a patient’s own suppressive regulatory T cells (Tregs) is an attractive biologic approach to reduce this burden. Here, we review the immunologic underpinnings of Treg therapy and technical challenges to developing successful cell therapy. These issues include the selection of appropriate Treg subsets, ex vivo Treg expansion approaches, how many Tregs to administer and when, and how to care for patients after Treg administration.

Polycystic liver disease is a well described manifestation of autosomal dominant polycystic kidney disease (ADPKD). Biliary tract complications are less well recognized. We report a 50-year single-center experience of 1007 patients, which raised a hypothesis that ADPKD is associated with biliary tract disease. We tested this hypothesis using all England Hospital Episode Statistics data (1998–2012), within which we identified 23,454 people with ADPKD and 6,412,754 hospital controls. Hospitalization rates for biliary tract disease, serious liver complications, and a range of other known ADPKD manifestations were adjusted for potential confounders. Compared with non-ADPKD hospital controls, those with ADPKD had higher rates of admission for biliary tract disease (rate ratio [RR], 2.24; 95% confidence interval [95% CI], 2.16 to 2.33) and serious liver complications (RR, 4.67; 95% CI, 4.35 to 5.02). In analyses restricted to those on maintenance dialysis or with a kidney transplant, RRs attenuated substantially, but ADPKD remained associated with biliary tract disease (RR, 1.19; 95% CI, 1.08 to 1.31) and perhaps with serious liver complications (RR, 1.15; 95% CI, 0.98 to 1.33). The ADPKD versus non-ADPKD RRs for biliary tract disease were larger for men than women (heterogeneity P<0.001), but RRs for serious liver complications appeared higher in women (heterogeneity P<0.001). Absolute excess risk of biliary tract disease associated with ADPKD was larger than that for serious liver disease, cerebral aneurysms, and inguinal hernias but less than that for urinary tract infections. Overall, biliary tract disease seems to be a distinct and important extrarenal complication of ADPKD.

Oratio: A Non-Lawyer's Views on the Revised White Paper on Arts, Culture and Heritage of 2013
Authors: Van Graan Mike
Published: May 2017

The South African Department of Arts and Culture (DAC) recently published for comments a Revised White Paper on Arts, Culture and Heritage (the White Paper) dated 4 June 2013.[1] The White Paper contains a new vision of arts and culture and is intended to replace the existing White Paper on Arts, Culture and Heritage dated 4 June 1996 (the 1996 White Paper).[2] The publication of a revised white paper on cultural matters after 17 years is definitely not unwelcome but in this case a number of issues which need to be raised come to the fore.

Werknemers as Lasgewende Ouers in Surrogasie-Aangeleenthede: Die Geboorte van nuwe Verlof-behoeftes in Suid-Afrika / Employees as Commissioning Parents in Surrogacy Matters: The Birth of New Leave Requirements in South Africa
Authors: Botes Anri , Fourie Laetitia
Published: May 2017

Commissioning parents, in terms of a surrogacy agreement, have the same parental obligations towards their child as traditional parents. Yet, despite the legitimising of surrogacy in the Children’s Act 38 of 2005, no provision has been made for suitable parental leave to be granted to these persons so that they may fulfil their parental obligations. The only leave that is currently available to commissioning parents is three days family responsibility leave in terms of section 27 of the Basic Conditions of Employment Act 75 of 1997 (BCEA). It is submitted that this leave is insufficient. In MIA v State Information Technology Agency 2015 36 ILJ 1905 (LC), the Labour Court indicated that amendments to labour legislation are necessary to address the lacuna in this respect. The Labour Laws Amendment Bill of 2015 has since proposed relevant amendments to such leave in terms of the BCEA. While the amendments are welcomed, the proposed period and management of the different types of leave give rise to concern and should be addressed. The latest developments in the United Kingdom in the field of parental leave make it a worthy comparator to provide guidelines for the improvement of the abovementioned Bill. In so doing, South African law can also sufficiently protect the interests of the parties to a surrogacy agreement, including the child born in terms thereof.

Lasgewende ouers ingevolge ŉ surrogasie ooreenkoms beskik oor dieselfde ouerlike verpligtinge as tradisionele ouers teenoor hulle kind. Alhoewel dit waar is, word sedert die statutêre erkenning van surrogasie in die Kinderwet nog geen geskikte ouerskapverlof vir hierdie persone gebied om aan sodanige ouerlike verpligtinge te voldoen nie. Die enigste verlof tans tot lasgewende ouers se beskikking is drie dae gesinsverantwoordelikheidsverlof ingevolge artikel 27 van die Wet op Basiese Diensvoorwaardes 75 van 1997 (WBDV). Dit word aan die hand gedoen dat hierdie verlof onvoldoende is. In MIA v State Information Technology Agency 2015 36 ILJ 1905 (LC) het die Arbeidshof aangetoon dat wysigings in hierdie verband aan die arbeidswetgewing noodsaaklik is ten einde die betrokke leemte aan te spreek. Die Labour Laws Amendment Bill van 2015 het sedertdien relevante wysigings aan verlof tot die WBDV voorgestel. Terwyl die vermelde wysigings verwelkom word, is die periodes en die bestuur van die verskillende tipes voorgestelde verlof kommerwekkend en behoort dit aangespreek te word. Die resente regsontwikkeling in die Verenigde Koninkryk op hierdie gebied kan as ŉ waardevolle vergelykende maatstaf dien ten einde riglyne vir die verbetering van bogenoemde konsepwet te bied. Sodoende kan ook die Suid-Afrikaanse reg die belange van die partye tot ŉ surrogaatooreenkoms, insluitende die van die kind daaruit gebore, na behore beskerm
Foreign Language Assessment: Instructional Considerations for Students with Specific Learning Disabilities
Authors: Tolbert Joshua B. L.
Published: May 2017

Students with specific learning disabilities (SLDs) continue to be more likely to experience anxiety about learning a foreign language, and possibly less likely to enroll in foreign language courses at all. As schools become more inclusive and more aware of diverse learning needs, it is important to be cognizant of how the individual needs of students with SLDs may relate to classroom instruction and assessment practices. What follows is a discussion of assessment practices, with an emphasis on diagnostic and formative assessment in the context of teaching students with SLDs. Given the prevalence of mobile phones and other devices in contemporary classrooms, a strong emphasis on the role of online polling resources plays a prominent role in this discussion. Specific examples of instructional activities which align with assessments are also provided, as part of a selective literature review intended to connect larger topics in language instruction to the typical needs of students with specific learning disabilities. The perspective of the discussion pertains primarily to students with SLDs in the United States, where the vast majority of foreign language instruction occurs in the middle and secondary grades.
Expatriate TESOL Teachers’ Perception of Professionalism: A Study in Saudi Context
Authors: Eusafzai Hamid Ali Khan
Published: May 2017

Within the teaching field, the concept of professionalism has recently become controversial. Neo-liberalism has eroded the traditional meanings of teachers’ professionalism and teachers are grappling with an uncertain situation regarding their professional status. To end the uncertainty and resolve the controversial nature of the concept, approaching professionalism from teachers’ own perspectives has been advocated. The current study, using a qualitative research methodology, explores teachers’ perceptions of the concept and nature of professionalism. The study discovered that teachers clearly regard themselves and their profession as a classic profession and of great service to the society and this perception also guides their approach to their routine work.
Indonesian EFL Students’ Perceptions on the Implementation of Flipped Classroom Model
Authors: Afrilyasanti Rida , Cahyono Bambang Yudi , Astuti Utari Praba
Published: May 2017

The flipped classroom model has gained popularity in education recently. In this model of learning, the students learn materials (e.g., by watching lectures through video) at home, and then they learn more actively in the school classroom. Although flipped classroom model has been popular, the implementation of flipped classroom in an English as a Foreign Language (EFL) context has not been widely published. This article reports results of research examining students’ perceptions on the implementation of the flipped classroom model. It involved 30 senior high school students who joined a writing class using flippled classroom model. Data were collected by using questionnaires, immediate interview and observations. The results of the research showed that the students found the activities applied in the flipped classroom model helped them write better. The videos they watched as well as teacher and peer feedback in their writing process improved their writing ability. This study also presented some caveats for teachers when they intend to flip the class.
The Implementation of Natural Semantic Metalanuage and Semantic Field in Language Teaching: A Case Study
Authors: Arnawa Nengah
Published: May 2017

This study aimed at developing a model of learning Balinese vocabularies by implementing Natural Semantic Meta-language (NSM) and semantics field theory. This finding was expected to establish a natural atmosphere of Balinese learning based on semantics primes. Semantics primes development on the basis of semantic field can overcome abstractness meaning of certain words. To prove the truth of the theory construction, the researcher modified a research and development which refers to Borg and Gell models. Data were collected before and after the development of model with certain indicators: the rapid in understanding words meaning, skill in using the word in natural sentence structure, and students’ learning creativity. Significance was measured by using t-test formula for correlated samples. Based on statistical analysis, it was proved that the implementation of NSM and semantic field theory was very effective (significant) in learning Balinese vocabularies on students grade 1, 2, and 3. Effectiveness of learning was achieved because the materials adhering to the natural principle of language acquisition and the availability of direct meaning comparison between words were intuitively related. Direct comparison could overcome the cognitive limitations of students grade 1, 2, and 3 in primary school.

Published: May 2017

The purpose of this research was to examine the impact of transferring and contriving the perspective and message from a collection of written or spoken text, in the context of teaching English writing as foreign d language. The entire research was conducted with a view to create a writing strategy for use in the popular EFL workbook, New Interchange 3. The research further developed into concept mapping the learners’ ability at a pre-writing stage on English as a foreign language (EFL) to generate better argumentative essays. On the basis of the results achieved through analytical and experimental case study, the paper intended to design a course plan for the non-native learners of English in the TEFL Writing classes at the College of Languages and Translation, King Saud University. The paper further evaluated and examined the usefulness of the language tools of corpus, collocation and context as pre-writing strategies. It has been the desired objective of the researcher to observe, analyze, and establish the importance of corpus, collocation and context (C3) as viable pre-writing tools. A case study was conducted to ascertain and present the scientific practicability of the teaching of transferring and manipulating a context as a pre-writing strategy.
Slave-master Relationship and Post-colonial Translation and Teaching
Authors: Behnam Biook , Azimi Farhad , Kanani Alireza Baghban
Published: May 2017

Two hundred years after Hegel, his Master-Slave Dialectic theory is still one of the most controversial philosophical theories. Some believe that such a relationship does no longer exist, nor is it acceptable in the face of abolishment of slavery in the world. In this study, it has been tried to form an understanding of the Hegelian Master-Slave Dialectic and bring into light the presence of the Master-Slave relationship in our modern day world. As Crossley (1996) points out, the power relation in Hegelian dialectic philosophy is ever-present in a more subtle manner in the Post-colonial era; one which utilizes an intersubjective relationship, sustaining the other as a subject of action rather than attempting to negate them (p. 147). To establish this kind of power relation, the west has been employing language, literature and translation in a much more effective way than military might to assert her control and dominance, and move the wheels of colonization and an asymmetrical power relation forward.
The Impact of MOOCs on College English Reform in Mainland China
Authors: Cao Min
Published: May 2017

Massive Open Online Courses (MOOCs) are internationally accepted as a popular online learning, its introduction into Mainland China provides an opportunity for College English education reform, which is on progress since 2007. This article attempts to draw a picture of College English teaching reform under the influence of MOOCs by adopting documentary research method through analyzing all the essays about College English teaching under the wave of MOOCs in CNKI (China National Knowledge Infrastructure) according to their research contents. The data collected shows that theoretically College English teaching could be reformed by taking the form of MOOCs in the courses of English for general purposes (EGP), English for general education (EGE), and English for specific purposes (ESP). It seems that during the reform teaching models and student-teacher relationship are altered by the MOOCs environment. Additionally, College English courses on several MOOCs platforms are analyzed, they further prove the practical College English courses done on MOOCs platforms. This paper seems to throw light on a general overview of College English teaching in Mainland China for English teachers and researchers and propose further improvement for college English teaching reform.

Etiologic characterization of vulvovaginitis among females attending a tertiary care hospital: a one year study
Authors: Kiran Chembetei Kavitha , Kandati Jithendra , Ponugoti Munilakshmi
Published: May 2017

Background: Vulvovaginitis is one among the major pathologies encountered in reproductive age group. Etiologies are always multiple and candidiasis, bacterial vaginitis and trichomoniasis account for 90% of etiology. The incidence is dependable upon multiple factors like age group, ethnicity, socioeconomic status, geographical locale. Improperly treated and untreated vulvovaginitis is associated with long term complications like infertility, pelvic inflammatory disease in nulliparous females and preterm labour, miscarriage, ectopic pregnancy, chorioamnionitis among pregnant females and recurrent UTIs, cervicitis, endometritis, increased risk of acquiring STIs among normal females. The present study was undertaken with the objective of understanding the etiologies associated with vulvovaginitis among women attending Obstetrics clinic of a tertiary care hospital. The risk factors associated with the conditions, the features of the vaginal discharge and symptoms associated with each etiology were studied.Methods: A cross sectional study for a period of one year was conducted among 200 female patients attending the Department of gynecology for vaginitis and evaluated for etiology. Patient’s risk factors, clinical history, symptoms were collected by questionnaire and specimens were collected from all the cases and processed as per standard guidelines. Bacterial vaginosis was confirmed based on Neugent’s criteria, Trichomoniasis by wet mount examination and candidiasis by culture. The study was approved by the institutional ethical committee.Results: 137 cases of vulvovaginitis were diagnosed based on etiology. Vulvovaginitis was most common among 27-36 years and in multiparous women. Most common causative agent was Candida (59.12%) followed by bacterial vaginosis (22.63%) and Trichomoniasis (18.25%). Vaginal discharge was the commonest symptom (100%) followed by malodor and vulval irritation. Following unhygienic practices was the commonest risk factor associated with Vulvovaginitis.Conclusions: A regular evaluation is mandatory for all the females attending hospital for vaginitis. Successful management reduces the morbid conditions and it’s essential to treat the conditions during the pregnancy which prevents the complications associated like preterm birth, miscarriage etc. and adverse outcomes.
Study of blood pressure profile and anthropometry in children belonging to low socio-economic status; a prospective cross sectional study
Authors: Sudhakar Chidambram , Rahman Raisur
Published: May 2017

Background: A significant number of population in India are below poverty line. It contributes to the higher incidence of malnutrition especially among children which is 48% according to NFHS-3 (National family Health survey). Blood Pressure tracking studies suggest that hypertension in adulthood often has its origin in childhood. Blood pressure in childhood is the best predictor of hypertension in later life. There have been very few studies on malnutrition and Hypertension association and none in this area. One rationale for screening for hypertension in children and adolescents is that early identification of primary hypertension could lead to interventions to reduce blood pressure during childhood and adolescence, resulting in a reduced risk for cardiovascular events and death in adulthood.Methods: The present cross sectional prospective study was conducted on School going children (5-14 years) belonging to lower socio-economic status attending schools from Bhilai, DistrictDurg Chhattisgarh, India, within 5 km range of Chandulal Chandrakar Memorial Hospital over a period of 12 months from March 2015 to February 2016.The present study took 300 sample size. List of schools was arranged from district education officer (DEO) and required government schools were shortlisted on within 5 km range of hospital. After short history and examination, as per the prerequisite of proforma, the following measurements were taken. For all the statistical analysis MS EXCEL and SPSS 16 (Statistical Package for Social Science) version were used. The information collected was tabulated and the data was analyzed using suitable statistics.Results: 60% of the subjects were belongs to 5-10 years of age and 40% in 10-14 years’ age group. Males and females were equal in distributions (50% each), thus there were 150 males and 150 females in the current study. Overall prevalence of malnutrition in our study was 38.6%. The present study found 88 subjects (29.3%) having grade 1 malnutrition and 28 subjects (38.7%) having grade 2 and 0 (0%) with grade 3 and grade 4 malnutrition. There were 2 pre-hypertensives in our study, out of which one was male and one female. When analyzed according to nutritional status, there were 2 hypertensives in malnourished group. Similarly. there was 1 hypertensive in normal nutritional status group.Conclusions: There is a significant prevalence of malnutrition in our society which contributes to a more number of problems than what is presented to practicing paediatricians. The prevalence is higher in children <5 years age group overall which continues through school age and adolescent age group as shown in our study. The focus of attention should be identification of various diseases along with hypertension at the earliest and prevention of malnutrition.

Institutional assessment and pedagogical political project: two sides of the same coin

This article intends to analyze the articulation between institutional assessment (IAS) and pedagogical political project (PPP) based on a project conducted in a Brazilian municipality. It involved a sample of schools that developed a process for institutional assessment, in order to re-shape their PPP. We sought to examine whether and how these schools used the data from this assessment to reformulate their pedagogic projects. The text brings a reflection about the principles that guide and surpass the two processes. It aims both to evaluate the reason why it is so difficult to develop them and what their possibilities are.

Mutación m.3271T>C del gen MTTL1 en encefalopatía mitocondrial, acidosis láctica y episodios stroke like (MELAS) en edad pediátrica. A propósito de un caso
Authors: García-Beristain Juan Carlos , Barragán- Pérez Eduardo Javier
Published: May 2017

INTRODUCCIÓN: la encefalopatía mitocondrial, acidosis láctica y episodios stroke like (MELAS) es una enfermedad metabólica poco común, que usualmente se presenta con crisis epilépticas y episodios stroke like en personas jóvenes. Se ha visto que 7 a 15% de los pacientes con MELAS tienen transiciones T a C en la posición de nucleótido 3271 (T3271C). La mayoría de los pacientes descritos con esta asociación son de origen japonés. La alteración del estado mental y la esquizofrenia, que en ocasiones puede preceder o acompañar a los episodios stroke-like en MELAS, pueden encontrarse incluso en familiares afectados por la misma mutación en T3271C. Los niños con MELAS tienen amplio espectro de presentaciones clínicas, en las que predominan los episodios stroke like.OBJETIVO: describir los datos clínicos relacionados con la mutación m.3271>C del gen MT-TL1 en MELAS en un paciente.CASO CLÍNICO: niña de 11 años de edad en cuya historia había cuadro de enfermedad vascular cerebral con manifestaciones visuales principalmente y posterior deterioro hemodinámico franco con estado de choque, hiperlactatemia y desequilibrio ácido-base severo, lo que permitió determinar la presencia de la mutación m.3271T>C en heteroplasmia del gen MT-TL1 compatible con MELAS.CONCLUSIONES: se puede considerar que en los pacientes con alteraciones ácido-base severas e hiperlactatemia franca, que pueda condicionar inestabilidad hemodinámica o estado de choque, se encuentran en relación directa con esta mutación, por lo que en estos pacientes sería necesario un estudio inmediato ante la sospecha, incluyendo la confirmación molecular del mismo en vista de lo agresivo y progresivo del cuadro.

La Unión Europea constituye un espacio especialmente denso desde el punto de vista parlamentario y de una gran complejidad en relación con su naturaleza representativa. Para hacer frente a la desparlamentarización de sus instituciones se han propuesto dos estrategias cuyos alcances se analizan aquí: la implicación de los Parlamentos nacionales en la gobernanza europea y el fortalecimiento del Parlamento Europeo. En este artículo se examinan críticamente ambas propuestas. Para mejorar la representación en Europa se propone indagar las posibilidades de innovación representativa que permite una entidad política tan peculiar.

While it may seem obvious, the link between mobility and European Union (EU) has not been systematically explored. Mobility defined as “all movement involving a change in the state of the actor or system” does not represent a central concept for European studies and, when used, no common theoretical foundation is provided. Major contributions to explore the link between mobility and European Union come from migration studies planning theory and research on job and student mobility. Each of these fields has been developed separately. The present special issue of Cuadernos Europeos de Deusto represents an attempt to better conceptualise the role of mobility in the process of European integration.

Inclusive Mobility or Inclusive Accessibility? A European Perspective
Authors: Gallez Caroline , Motte-Baumvol Benjamin
Published: May 2017

“La movilidad inclusiva” es parte de las prioridades políticas definidas por numerosos países europeos para referirse a la dimensión social del transporte o las políticas de movilidad cotidiana. De forma general, la inclusión se refiere a la cohesión social, que ha sido uno de los objetivos declarados de la Unión Europea desde el inicio de los años 2000. Como mecanismo para facilitar el acceso a las oportunidades (empleo, comercio, servicios, etc.), la movilidad individual es actualmente considerada un prerrequisito necesario para la participación de las personas en las actividades sociales. En contraste, la inmovilidad o “ausencia de movilidad” sería un factor de exclusión social. Sin embargo, en razón de la ambigüedad de la movilidad, que puede considerarse un recurso esencial (facilitador de acceso a oportunidades en el contexto de una dispersión mayor de las actividades) o un coste (monetario, medioambiental, físico); un derecho básico o un precepto político para movilidad (los objetivos políticos de la movilidad pueden esconder algunas contradicciones). Este artículo se concentra en diferentes problemáticas en relación a la movilidad inclusiva en Europa. Para empezar, presentamos cómo el lema de la “movilidad inclusiva” es utilizado en los documentos oficiales de la Comisión Europea. Posteriormente, se analiza cómo la cuestión de la movilidad inclusiva ha emergido en Francia y en el Reino Unido, en relación a la generalización del problema de la exclusión social. Se completará esta visión de políticas públicas ofreciendo un panorama de las desigualdades sociales en relación a la movilidad cotidiana en diferentes países europeos. Finalmente, se argumenta la necesidad de evolucionar desde una prioridad política de la movilidad inclusiva hacia la accesibilidad inclusiva, considerando que las políticas de movilidad, como elemento favorecedor de la dispersión de las actividades, pueden incrementar la presión sobre los grupos sociales desfavorecidos para ser móviles.

Cuidados y servicios sociosanitarios para las personas en situación de dependencia, como parte integral del Sistema de Salud
Authors: Uprimny Yepes Miguel Antonio
Published: May 2017

Colombia vive un proceso de transición demográfica moderada. Las personas hoy se enferman de padecimientos crónicos, presentan pluripatología, sufren de polimedicación, soledad y desarraigo. La prevalencia de personas en situación de discapacidad permanente es significativamente alta con pérdida de su autonomía de manera aguda o crónica significativos, que requieren de cuidados, apoyos y ayudas técnicas que se surten de manera formal o informal para recobrarla o minimizar la dependencia. Las personas adultas mayores con dependencia, las que padecen enfermedad crónica o un episodio agudo incapacitante, las que padecen de algún grado de discapacidad, las que se encuentran en fase terminal y sus cuidadores son entre otros, los sujetos de estos cuidados. Centros Día, transporte especial, cuidadoras, cuidados domiciliarios, teleasistencia, son algunos que deben articularse con salud como parte de la integralidad. Las personas que son objeto de la atención sociosanitaria son en las que confluye una necesidad de servicios sociales y de salud.
Development of a platform for teaching basic programming using mobile robots
Authors: Bacca-Cortes Bladimir , Florián-Gaviria Beatriz , García Sergio , Rueda Sebastián
Published: May 2017

Mobile robotics is being used in different education contexts, such as basic, middle, and high-level education. A literature review showed that 197 papers have been published in this area of knowledge over the past 10 years. Nowadays, Latin America faces a serious problem due to the low student enrollment in engineering programs, where, depending on the country, the ratio of graduate engineers can be 1 per 4500 to 1 per 10 000 people. In Colombia, the SPADIES program of the Ministry of Education affirms that the lack of motivation and interaction with real artifacts relating theory and practice is an important aspect for dropout. In this paper, a platform composed by a set of programmable mobile robots, and a WEB-responsive software tool for programming at different levels of knowledge was implemented. The set of mobile robots included sensors such as proximity, trajectory, light, inertial, and vision; also, communication and user interaction tools, such as Bluetooth and colored LEDs-ring, and a mechanical support for an erasable marker were included. The WEB-responsive tool supports graphical programming for novice; Python programming, for middle; and ANSI-C, for advanced learners. This platform consolidates a hands-on tool to introduce students to STEM concepts. Results are reported in the context of platform functionality, using all three programming environments, and beta tests with real users.
Cinemática 2D de caballos al trote mediante videometría y modelamiento matemático
Authors: Torres-Pérez Yolanda , Gómez-Pachón Edwin Yesid , Miró-Rodriguez Francisco
Published: May 2017

Actualmente, el método de observación directa se utiliza para evaluar el movimiento de los caballos; sin embargo, este método es limitado dado que es totalmente subjetivo y muchos detalles de la funcionalidad del sistema músculo-esquelético no pueden ser detectados y evaluados, debido a que no son perceptibles a simple vista. El principal objetivo de este estudio fue desarrollar un modelo matemático que permita calcular, graficar y simular el movimiento angular, en dos dimensiones, de algunas articulaciones de los caballos. El aparato locomotor del caballo fue modelado como un sistema mecánico de cuerpos rígidos articulados por 15 juntas simples. La solución matemática del mecanismo se hizo desde el punto de vista del pasivo de la cinemática inversa (plana); se construyeron 15 ecuaciones de cadena, asociando los segmentos corporales del sistema en movimiento con la base inercial, y fue utilizado el método de optimización matemática basada en el cálculo de los mínimos cuadrados.En este estudio se obtuvieron las curvas cinemáticas de las principales articulaciones, las trayectorias (altura) de los marcadores sobre las bandas coronarias trasera y delantera (cascos) y una simulación del sistema mecánico. Esta herramienta elimina la subjetividad y permite a los veterinarios observar, evaluar (cualitativa y cuantitativamente), diagnosticar e investigar sobre diferentes fenómenos de la marcha de los caballos.

The 20th volume of the CLEI electronic journal includes six papers selected from an open call for papers on Natural Language Processing (NLP), processed by invited editors Gerardo Sierra and César Aguilar, and an additional regular paper. The NLP subject was suggested by Gabriela Marín and Antonio Leoni de León, the chairs of NLPCR 2016, the First Costa-Rican Colloquium on Natural Language Processing. The invited editors took care of the review process and the selection of the six papers, as discussed in their Preface which opens this issue.

The additional regular paper is a contribution by Jose Aguilar, Guido Riofrío, and Eduardo Encalada, titled "Learning Analytics focused on student behavior. Case study: dropout in distance learning institutions", which focuses on the use of Learning Analytics for undestanding student behavior in the context of distance learning universities, particularly focuses on the students’ behavior, with the goal of identifying factors that influence the decision of a student to abandon their studies, predicting students susceptible to abandon their studies, and defining their motivational patterns.

This issue, which opens the 20th volume of the journal, is a mark of the success of the mission of CLEIej as a vehicle for publishing Latin American based original research in subjects of international interest; we are glad to be able to develop this mission with the support of the researchers who kindly contribute their time as invited editors and reviewers of the papers received.
Etude préliminaire de l’importance de la cysticercose porcine en abattoir à Antananarivo, Madagascar

La cysticercose est une maladie parasitaire largement répan­due dans les pays en développement d’Amérique latine, d’Afrique et d’Asie. Cette maladie tropicale négligée représente une contrainte économique forte pour la filière porcine et un grave problème de santé publique à Madagascar. Plusieurs cen­taines de cas humains sont enregistrés chaque année dans les hôpitaux de la capitale malgache. Les éleveurs ruraux classent la cysticercose à la première place, devant les pestes porcines du fait de sa fréquence et de la perte économique qu’elle engendre. Cependant aucune donnée fiable sur l’importance réelle de la maladie chez le porc n’est disponible actuellement.Dans cette étude, les objectifs ont été, d’une part, d’évaluer l’importance de la cysticercose porcine dans les abattoirs qui approvisionnent les marchés d’Antananarivo et, d’autre part, d’identifier ses facteurs de variation. Un suivi d’abattoirs a été mis en place à partir de mars 2013 pour une durée d’un an. Deux principaux lieux d’abattage à Antananarivo ont été choi­sis. Une inspection de tous les porcs abattus et la collecte des données sur les facteurs de variation (race, origine, sexe, date) ont été effectuées.Après six mois de suivi, les résultats intermédiaires ont concerné l’abattoir d’Ankadindratombo. Sur 2 904 porcs abattus, issus de 12 districts répartis dans toute l’île, la prévalence de la cysti­cercose a été de 3,9 p. 100. L’incidence mensuelle a été de 19 porcs infestés. Parmi les facteurs de variation, la prévalence a varié selon les districts d’origine de 0 à 6 p. 100 (figure 1). Juillet a été le mois le moins à risque (odds ratio = 0,46 ; p = 0,05). La race locale a été plus à risque que les phénotypes exotiques (odds ratio = 2,40 ; p < 0,001). Bien qu’en attente de données complètes, ces résultats confirment dès à présent l’importance de la maladie chez le porc.
