A Case of Possible Hypersensitivity Reactions to Human Insulin
Authors: Adamescu Eduard , Tudose Adriana Mihaela , Dumitrescu Nicolae Viorel , Dobjanschi Carmen
Published: March 2016

Background: Insulin therapy is commonly used in diabetic patients. It represents the only option for patients with type 1 diabetes mellitus and could be part of the treatment plan for the patient with type 2 diabetes mellitus. Clinical appearance of hypersensitivity reactions to insulin vary significantly, depending on the immune mechanism involved. Many skin prick tests could be interpreted as positive reactions (either by using inappropriate concentrations or due to other mast cell degranulation causes).

Case History: Four weeks after initiation of insulin therapy, patient V.I. experienced a maculopapular rash, severe pruritus, induration at the injection site after 12-24 hours after administration. The presence of an insulin sensitization was proven by skin prick test and determination of specific IgE.

Discussions: Patients suspected of insulin hypersensitivity should be evaluated by an allergologist in order to obtain a correct diagnosis and to identify other possible causes for the insulin intolerance. Desensitization should be undertaken only in real insulin hypersensitivity cases in patients who need it.

Conclusions: Insulin allergy can be managed successfully with a good cooperation between the diabetologist and the allergologist.
The Effect of Pumpkin on GLP-1 and HOMA-β in Hypercholesterolemic Rats
Authors: Sunarti  , Rubi Dianandha Septiana , Sadewa Ahmad Hamim
Published: March 2016

Background and aim: High fat and fructose diet may impair β cell function through oxidative stress that is induced by subsequent hypercholesterolemia. The β cell function is usually quantified by homeostatic model assessment beta-cell function (HOMA-β). Oxidative stress may be decreased by β-carotene from pumpkin (Cucurbita maxima). This study aimed to evaluate the effects of pumpkin powder on glucagon-like peptide-1 (GLP-1) level and HOMA-β in rats with high fat and fructose diet.

Material and method: A total 25 rats were administered a high fat and fructose diet during 25 days. They were divided into five groups 1) normal, 2) hypercholesterolemic rats 3) hypercholesterolemic rats with 0.16 g pumpkin/200g bodyweight (BW); 4) hypercholesterolemic rats with 0.32 g pumpkin/200 g BW, and 5) hypercholesterolemic rats with 0.64 g of pumpkin/200 g BW. The lipid levels were measured before and after administration of pumpkin for 4 weeks, and at the end of the study, GLP-1 level and HOMA-β were analyzed.

Results: Administration of pumpkin to the rats on a high fat and fructose diet reduced total cholesterol, triglyceride, and increased HDL levels. Changes were positively correlated with the amount of pumpkin intake. The decrease of cholesterol levels was positively associated with GLP-1 level, and negatively correlated with HOMA-β

Conclusions: This study suggested that pumpkin can improve the HOMA-β and decrease GLP-1 levels, possibly by reducing cholesterol levels.
Liver and Metabolic Diseases

Published: March 2016

Chronic liver diseases and metabolic disorders represent two real public health problems that cause increased morbidity and mortality in a significant number of people worldwide. The most common cause of chronic liver disease is represented by non-alcoholic fatty liver disease (NAFLD). Hepatic inflammation is a critical event in the progression of NAFLD and excess adiposity, through the hormones and cytokines secreted by the adipose tissue, plays an important role. There is ample evidence supporting a significant association between chronic hepatitis C (CHC) and metabolic disorders. CHC may be considered not just a viral disease, but also a metabolic type condition. Multiple pathogenic mechanisms have been proposed to explain the interaction between hepatitis C virus and impairment of glucose and lipid metabolism and diabetes. The relationship between hepatitis B infection (HBV) and metabolic diseases remains uncertain.
The Emerging Role of SGLT2 Inhibitors in the Treatment of Type 2 Diabetes. Focus on Dapagliflozin
Authors: Timar Bogdan , Serafinceanu Cristian , Vlad Adrian , Timar Romulus
Published: March 2016

Type 2 diabetes is a progressive metabolic disorder, accounting for more than 90% of all cases of diabetes. Treatment strategies target blood glucose reduction and non-glycemic effects that can reduce long-term complications, such as cardiovascular disease. Although metformin is often initially effective as monotherapy, the progressive nature of diabetes frequently requires additional therapies. Sodium-glucose transporter 2 (SGLT2) became a very attractive therapeutic target in diabetes management. The mechanism of action of SGLT2 inhibitors is not dependent on insulin, thus making them attractive options anytime over the course of the disease. Dapagliflozin is a stable and highly selective inhibitor of SGLT2. The reductions in fasting plasma glucose concentration and bodyweight recorded during the first week of treatment in the dapagliflozin groups continued over weeks and years of treatment. Early weight loss with dapagliflozin might be partly due to a mild osmotic diuresis, while the gradual progressive reduction in bodyweight is consistent with a reduction of fat mass. Although dapagliflozin is well tolerated, signs and symptoms suggestive for urinary and/or genital infections were reported during clinical trials in more patients assigned to the drug than in placebo groups.

Authors: Tascu A. , Spatariu A. , Pascal C. , Iencean St.M.
Published: March 2016

Infratentorial subdural empyema is a life-threatening condition, the common source being an ear infection. We present a 2-year old boy treated for bilateral mastoiditis, with infratentorial-left cerebellopontine angle subdural empyema. Clinical presentation encompassed a systemic febrile illness, headaches, and a stiff neck. Empyema was diagnosed with computed tomography and magnetic resonance imaging. The patient was successfully treated with surgery and appropriate antibiotics. Empyema should be considered in patients with ENT infection associated with neurological signs that suggest a posterior fossa lesion.
Asymptomatic posterior cervical myelomeningocele with tethered cord in an adolescent: a rare form of spinal dysraphism with rare presentation
Authors: Gunjan Gangesh , Sharma Sumit , Jain S.K. , Chopra S.
Published: March 2016

Unlike lumbar spinal dysraphism, cervical spinal dysraphism with or without tethered cord are rare lesions. These lesions are generally asymptomatic at birth, but with progression of time symptoms develop. These may be associated with various other anomalies. Not much have been reported in literature about cervical myelomeningocele (MMC) in adults or adolescents. We report a case of a 17 years old adolescent boy with cervical myelomeningocele with tethered cervical cord, who was completely intact neurologically even at this age and was without any associated anomaly. He came to us only for cosmetic reasons. The tethering band, which was evident on imaging was confirmed intra-operatively.
Eyes without a ribbon
Authors: Moser Tobias
Published: March 2016

Eye and ear employ specialized glutamatergic synapses that feature an elaborate electron‐dense projection—the synaptic ribbon. Despite major efforts, the function of the synaptic ribbon has remained enigmatic, because its brick‐stone‐like core‐component RIBEYE has remained hard to crack genetically. In an elegant study, Maxeiner et al () genetically deleted RIBEYE in mice. This abolished retinal ribbons and impaired exocytosis at the presynaptic active zone of bipolar cells.

Predictive value and construct validity of the work functioning screener‐healthcare (WFS‐H)
Authors: Boezeman Edwin J. , Nieuwenhuijsen Karen , Sluiter Judith K.
Published: March 2016

Objectives

To test the predictive value and convergent construct validity of a 6‐item work functioning screener (WFS‐H).

Methods

Healthcare workers (249 nurses) completed a questionnaire containing the work functioning screener (WFS‐H) and a work functioning instrument (NWFQ) measuring the following: cognitive aspects of task execution and general incidents, avoidance behavior, conflicts and irritation with colleagues, impaired contact with patients and their family, and level of energy and motivation. Productivity and mental health were also measured. Negative and positive predictive values, AUC values, and sensitivity and specificity were calculated to examine the predictive value of the screener. Correlation analysis was used to examine the construct validity.

Results

The screener had good predictive value, since the results showed that a negative screener score is a strong indicator of work functioning not hindered by mental health problems (negative predictive values : 94% ‐98%; positive predictive values: 21%‐36%; AUC: .64‐.82; sensitivity: 42%‐76%; and specificity 85%‐87%). The screener has good construct validity due to moderate, but significant (p<.001), associations with productivity (r=.51), mental health (r=.48), and distress (r=.47).

Conclusions

The screener (WFS‐H) had good predictive value and good construct validity. Its score offers occupational health professionals a helpful preliminary insight into the work functioning of healthcare workers.

Published: March 2016

Evaluation of tribological behaviour of Fe-W, Ni-W and Co-W coatings produced by electrodeposition at various bulk current densities (BCD) was under investigation in the given study. BCD does not have essential effect on the microhardness and wear characteristics of Fe-W and Co-W coatings. But the scratch tests reveal the presence of such influence. These tests showed superior wear resistance for the coatings obtained at low BCD. It was found that BCD has influence on wear resistance of Ni-W coatings under dry friction conditions. The BCD also has an influence on the coefficient of friction of Fe-W and Ni-W coatings at dry friction conditions. However, such an effect is opposite to that, observed at the scratch test.

Authors: Leitans A. , Bulaha N. , Lungevics J.
Published: March 2016

Carbon-copper composite coatings were deposited using high power magnetron sputtering technique. Tribological tests were performed using ball-on-disk type tribometer. Friction coefficient and wear rate were determined at 40 N load. It was found that an increase in the percentage composition of carbon in C-Cu coating, reduces the coefficient of friction value. But at higher concentrations of C coating it becomes more brittle, that reduces wear resistance.

Authors: Kasprzycka E. , Bogdanski B.
Published: March 2016

A new technological processes combining a vacuum titanizing with a preliminary electrolytic deposition of Co-W alloy on the tool steel surface have been proposed to increase the corrosion resistance of carbide layers of TiC type. As a result, duplex layers of TiC+(Co-W) type on the steel surfaces have been obtained. It has been proved, that the wear resistance by friction of these duplex layers, produced by means vacuum titanizing of steel covered with electrolytic coating, is such good as the TiC carbide layers, produced on the steel surface without electrolytic coating, but their corrosion resistance is higher.

Published: March 2016

Three-dimensional printing or 3D printing (also called additive manufacturing) is any of various processes used to make a three-dimensional object. Fused deposition modelling (FDM) is an additive manufacturing technology commonly used for modelling, prototyping, and production applications. It is one of the techniques used for 3D printing. FDM is somewhat restricted in the size and the variation of shapes that may be fabricated. For parts too large to fit on a single build, for faster job builds with less support material, or for parts with finer features, sectioning and bonding FDM parts is a great solution. The strength of adhesive bonded FDM parts is affected by the surface roughness. In this study, the layer thickness effect on bonding strength is experimentally studied and the results are discussed.

Authors: Figueiredo-Pina C.G. , Moreira V. , Colaço R. , Serro A.P.
Published: March 2016

The relative motion between the zirconia abutment and the titanium implant in the presence of saliva might lead to tribocorrosion and consequently metal ion release and ion contamination of peri -implant tissues. In order to study this issue tribocorrosion, tests were performed in open circuit potential (OCP) and during anodic polarization in two different configurations: titanium ball pin on zirconia plate and zirconia ball pin on titanium plate. For both configurations, the OCP decreases and the anodic current increases during the wear testing. The results showed different tribocorrosion response between configurations. The higher OCP drop and anodic current was obtained for the configuration titanium ball pin on zirconia plate.

Authors: Padgurskas J. , Reškevičius G. , Zicans J. , Merijs Meri R. , Bochkov I.
Published: March 2016

Self-lubricating polymer composite are used more and more in tribological applications. Parts from these composite are good alternatives where conventional elements cannot be employed easily, for example in medical equipment, food industry. They have several advantages in comparison to metal ones: low weight, often no lubrication is required, low noise level, excellent mechanical damping effect, favorable friction etc. Self‐lubrication is characterized by ability to transfer microscopic amounts of material to the mating surface. This transfer process creates a film that provides lubrication and reduces friction over the length [1-2]. This paper focuses on mechanical properties: tensile strength, flexural strength, impact resistance, hardness, density and tribological properties results derived by bloc-on-ring tests. Investigations of friction and wear resistance of polymers and polymers with additives, using the SMC-2 device has been carried out in the present work. Used basic material (POM) and two types of nanoparticles (copper oxide and expanded graphite) by mixing them with five different concentrations (0 %; 0.5 %; 3 %; 7.5 % and 15 %) by volume. The influences of parameters like normal load, speed and time were considered variable value in the wear tests.

Published: March 2016

This study aims to evaluate the effect of a 6 % hydrogen peroxide (H 2 O 2 ) solution, activated with UV-light, in colour, wear, microhardness and roughness of enamel surface. Five teeth were cut, polished and exposed to black tea solution to confer them a dark color. The specimens were tested before and after bleaching using a spectrophotometer colour equipment, a nanotribometer, a micro durometer and a SEM. On comparing with untreated, the treated enamel surface showed an improvement of colour but a reduction of microhardness and an increase of roughness and wear. A 6 % hydrogen peroxide solution, activated with UV-light, has capacity to induce alterations in enamel surface making it less hard and more susceptible to wear.
Calculation of transonic flows around profiles with blunt and angled leading edges
Authors: Ngoc Hoang Thi Bich , Hung Nguyen Manh
Published: March 2016

Transonic flow is a mixed flow of subsonic and supersonic regions. Because of this mixture, the solution of transonic flow problems is obtained only when solving the differential equations of motion with special treatments for the transition from subsonic region to supersonic region and vice versa. We built codes solving the full potential equation and Euler equations by applying the finite difference method and finite volume method, and also associated with software Fluent to consider the viscous effects. The analysis of results calculated for cases of transonic flow over profiles with blunt and angled leading edges shows more clearly the physical nature of the gas - solid interaction at leading edges in the mixed flow and the optimal application of each profile in transonic flows.

Published: March 2016

ABSTRACT Objective To assess cardiorespiratory capacity through subjective and objective tests in older adults diagnosed with major depression (MDD), Alzheimer disease (AD) and healthy older adults. Methods Fifty seven subjects (72 ± 7.9 years) were divided into three groups: MDD (n = 20), AD (n = 17) and Healthy (n = 20). The subjects answered Hamilton Scale (HAM-D), Mini-Mental State Examination (MMSE), Veterans Specific Activity Questionnaire (VSAQ) and 2-minute Step test. Results MDD and AD showed lower scores than healthy group for Nomogram VSAQ (p < 0.001) and 2-minute Step (p = 0.009; p = 0.008, respectively). Adjusted for age and educational level, no differences among groups were observed for Step (MDD, p = 0.097; AD, p = 0.102). AD group did not present differences to healthy group for Step, when adjusting for MMSE (p = 0.261). Conclusions Despite the lower cardiorespiratory fitness of elderly patients with DM and DA have been found in both evaluations, the results should be viewed with caution, since the tests showed low correlation and different risk classifications of functional loss. In addition, age, level educational and cognitive performance are variables that can influence the performance objective evaluation.

Published: March 2016

In this study, we report the temporal occurrence and habitat and microhabitat use by anurans in two areas located in one highland marsh (brejo-de-altitude) in northeastern Brazil. Fieldwork was carried out between September 2011 and September 2012. The recorded anurans belong to 14 species distributed in five families: Hylidae (six), Leptodactylidae (five), Bufonidae, Odontophrynidae and Pipidae (one each). Vocalization activity was seasonal and concentrated in the wetter and warmer months, but correlated to rainfall only in the top in the Chapada do Araripe. Richness and abundance of calling anurans were lower in the humid forest of the slope than in Cerradão area in the top of the Chapada do Araripe. Scinax x-signatus vocalized during nine months, and along with Dendropsophus soaresi, Phyllomedusa nordestina and Physalaemus cuvieri presented the longest periods of vocalization with the highest number of species vocalizing in at the height of the rainy season. Males were recorded vocalizing in nine different microhabitats, Adenomera sp. uses leaf litter and P. cuvieri the edge of water bodies as calling site both two sampled areas. Differences in richness and abundance of anurans between the two habitats are probably due to physical characteristics, such as presence of lentic environments.
Uma análise epistemológica da estratégia organizacional no âmbito da economia social
Authors: Cruz Filho Paulo Roberto Araujo
Published: March 2016

Resumo Este artigo apresenta uma análise epistemológica dos trabalhos científicos que se concentram no estudo da estratégia organizacional no âmbito das empresas de economia social. Combinando estudos epistemológicos de dois campos do conhecimento, a estratégia organizacional e a economia social, este artigo objetiva compreender se o conjunto de estudos que, hoje, compõe o corpo teórico sobre a estratégia das empresas de economia social seria suficientemente sólido para sustentar o desenvolvimento de conhecimento próprio acerca das particularidades estratégicas dessas organizações. A análise baseou-se em uma revisão da literatura sobre o tema, que identificou 74 trabalhos sobre estratégia organizacional em uma base de dados contendo mais de 3.000 estudos em economia social. Uma ficha de análise constituída por cinco elementos foi elaborada a partir das posturas epistemológicas adotadas nos ramos da estratégia e da economia social: foco, ideologia, evolução da estratégia, definição da estratégia e postura. Como resultado, três categorias de estudos foram identificadas, de acordo com a natureza fundamental da definição da estratégica adotada: a estratégia como um conteúdo pragmático, a estratégia como um processo analítico e a estratégia como uma escolha estrutural. As conclusões apontam que o estudo da estratégia organizacional na economia social apresenta uma evolução cuja tendência é a realização de estudos cada vez mais concentrados na investigação das particularidades estratégicas específicas dessas organizações.
REDEFINIÇÕES DA CONDIÇÃO DE MORADOR: classificações das clientelas no mandato policial cotidiano e suas consequências nas relações entre polícia e população
Authors: Barbosa Wendell de Freitas , Sá Leonardo Damasceno de
Published: March 2016

Este artigo discute etnograficamente como estilos de patrulhamento policial interferem na situação de interpelação e resposta que envolve a interação entre policiais e moradores em espaços urbanos. Analisa como a condição de morador é mobilizada por policiais militares de uma área do Programa de Policiamento Ronda do Quarteirão, na cidade de Juazeiro do Norte, no sul do Ceará. Essa experiência de policiamento comunitário, nomeada como sendo “a polícia da boa vizinhança”, agrega, também, elementos de policiamento ostensivo convencional e nela os moradores são moralmente classificados pelos policiais em diversos rótulos, como revela o uso da oposição entre os termos “vagabundo” e “cidadão de bem”. Essas maneiras policiais de falar sobre moradores compõem agenciamentos de poder que atribuem formas de subjetividade aos moradores. O significado da “aplicação da lei” torna-se polissêmico, na medida em que os moradores são afetados por esses rótulos, sendo validados, revalidados, selecionados ou ignorados em cada situação.

Published: March 2016

RESUMO O artigo discute as possibilidades de uma aprendizagem evolutiva na formação de professores, tendo como referência os propósitos habermasianos de continuação do mundo da ação e do mundo discursivo. O estudo, de natureza reconstrutiva, analisou as abordagens paradigmático-epistemológicas que perpassam as teses de doutorado sobre formação de professores, defendidas nas universidades federais brasileiras, no triênio de avaliação da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) (2007-2009). Buscou-se identificar os elementos que caracterizam as abordagens: materialista-histórica, fenomenológico-hermenêutica, epistemologia da prática, epistemologia da complexidade, teoria da representação social e pós-estruturalista. Concluiu-se que perdura nas diferentes abordagens de pesquisa um eixo comum de objetividade caracterizada pelas certezas compartilhadas e pelo foco nas mesmas problematizações, o que explicita a possibilidade de continuação evolutiva entre o que a realidade ensina na experiência com o mundo e o que se aprende na interação argumentativa.

O presente estudo traz a debate os desafios colocados à (re)construção da identidade do professor, que se deslocou de um nível de não reflexividade para um metanível de atividade reflexiva e crítica, pondo em tensão a unidade e a continuidade da identidade, nas dimensões individual e coletiva, de onde pode emergir o sujeito da transformação social. Tratando-se de um processo interativo de (re)construção de sentido, a identidade do professor não dispensa a prática comunicacional e requer um pensamento reflexivo crítico e uma intervenção ativa, que depende do envolvimento do professor e está relacionado com o profissionalismo e a competência profissional.
Modelling Overnight RRP Participation
Authors: Anderson Alyssa G. , Huther Jeffrey W.
Published: March 2016

We examine how market participants have used the Federal Reserve’s overnight reverse repurchase (ON RRP) exercise and how short-term interest rates have evolved between December 2013 and November 2014. We show that money market fund (MMF) participation is sensitive to the spread between market repo rates and the ON RRP offering rate as well as Treasury bill issuance, government sponsored enterprise (GSE) participation is more heavily driven by calendar effects, dealers tend to only participate when rate spreads are negative, and banks generally do not participate. We also find that the effect of the ON RRP on overnight interest rates is more significant in the collateralized market than the uncollateralized market.

AUTONOMÍA PARA APRENDER Y AUTONOMÍA PARA vivir
Authors: Narváez Ribero Miryan
Published: March 2016

El sistema educativo tiene el reto actual de formar individuos autónomos. Esta autonomía no implica solo el que las personas tengan los recursos necesarios para aprender a aprender, sino que puedan convivir armónicamente en comunidad, escuchándose a sí mismos para tomar sus propias decisiones, sin estar determinados por deseos instintivos ni modelos coercitivos impuestos por la sociedad. Así, para desarrollar autonomía, le corresponde a la educación trabajar tres elementos: la voluntad, la libertad y la autoestima. De esta forma, una educación promotora de una verdadera autonomía deberá tener un carácter dialógico, haciendo hincapié en la integración solidaria de la persona con su comunidad. Nos referimos a una persona que no ha renunciado a sus metas ni aspiraciones, sino que sabe cómo guiarlas hacia un proyecto común de bienestar general.
INFLUENCIA DE LA AUTOEFICACIA EN EL ÁMBITO ACADÉMICO
Authors: Ruiz Dodobara Fernando
Published: March 2016

La autoeficacia o creencia en la propia capacidad en determinadas situaciones puede ser considerada un concepto vital en el ámbito educativo, puesto que es un elemento que predice de mejor manera el desempeño de la habilidad y del conocimiento personales. Este concepto se inserta dentro de la Teoría Social Cognitiva de Bandura, en la cual se considera al ser humano como un individuo autorganizado, autorreflexivo, autorregulado y comprometido con su desarrollo. Un punto clave en esta teoría es que las personas tienen creencias personales (creencias de autoeficacia), que les permiten ejercitar cierto control sobre sus sentimientos, acciones y pensamientos. Esto quiere decir que el comportamiento de los individuos se ve influido por lo que piensan, creen y sienten. Así, pues, la autoeficacia se convierte en un buen elemento de predicción del comportamiento humano. Las creencias de autoeficacia influyen en la conducta en general, mediante procesos cognitivos, motivacionales, afectivos y selectivos. Específicamente, en el ámbito académico, las creencias de autoeficacia actúan sobre la motivación, la persistencia y éxito académico. Cabe mencionar, también, que las creencias de autoeficacia que los profesores tienen acerca de su labor tienen una influencia importante en el desempeño de los alumnos. Finalmente, podemos mencionar que, entre las fuentes de autoeficacia, se encuentran el manejo exitoso de experiencias, la comparación con modelos similares, la persuasión social y los estados corporales.
EDUCACIÓN MÉDICA: NUEVAS TENDENCIAS, DESAFÍOS Y OPORTUNIDADES
Authors: Risco de Dominguez Graciela
Published: March 2016

El presente artículo trata sobre las pautas que deben tener en cuenta las escuelas de Medicina para responder a los desafíos y nuevas tendencias de la sociedad actual. En este contexto se valora la Educación Basada en Competencias (EBC), que es considerada como el modelo educativo predominante en las escuelas de Medicina del mundo y a su vez la revolución más importante en la educación médica para el siglo XXI. Los nuevos médicos deberían tener las siguientes características: una formación integral comprometida con la recuperación y promoción de la salud, una concepción integral del hombre y la salud, una sólida formación científica, estar preparado para liderar y trabajar en equipos multidisciplinarios, poseer habilidades directivas y de gestión, entre otras; para lograr ello se requieren de nuevas metodologías educativas como la Educación Basada en Problemas. Por ello en el Perú es necesario tomar en cuenta estos criterios para formar a médicos capaces de resolver la situación crítica de salud de la población, este compromiso inspiró a la creación de la Escuela de Medicina de la Universidad Peruana de Ciencias Aplicadas (UPC).
DESAFÍO DOCENTE: EL ALUMNO POSTMODERNO
Authors: Alfaro Ramírez Teresa
Published: March 2016

Las sociedades progresan: la actual, en un mundo que comandan la globalización y la informática, es una sociedad postmoderna. En ella, se han modificado las formas de transmitir y relacionar socialmente la cultura; se han desarrollado nuevos seres humanos, individuos postmodernos con características muy particulares: ellos son nuestros alumnos. ¿Cómo optimizamos la tríada del aprendizaje (alumno-docente-conocimientos)? No basta saber los contenidos y ser un especialista en la materia; es indispensable ser conscientes del entorno actual para analizar y comprender las características de nuestros alumnos, también denominados “hijos de la globalización” o “nativos digitales”. Solo así conoceremos, asimismo, nuestra propia realidad como individuos y docentes. El presente ensayo procura analizar las características de nuestros alumnos y reflexionar sobre nuestro papel como docentes en un entorno complejo y cambiante.
EL PROBLEMA DE COMPRENSIÓN Y PRODUCCIÓN DE TEXTOS EN EL PERÚ
Authors: Ramos Moises
Published: March 2016

Este artículo busca explicar el problema de la lectoescritura en el Perú; se enfoca en la carencia de información respecto a cómo los niños aprenden o adquieren el sistema de escritura, que posibilita la alfabetización inicial. Propone a las universidades e institutos pedagógicos incorporar a sus currículos un enfoque más próximo al desarrollo del niño; concretamente, al periodo de los primeros siete años, cruciales para su formación como lector y redactor.Asimismo, invoca a declinar las prácticas tradicionales, que condicionan el fracaso de lectores activos y reflexivos desde la educación inicial y que explican, en parte, por qué los universitarios y profesionales peruanos leen poco o se limitan a escribir textos breves. En esa línea, expone las dificultades que tiene el alumno para emplear la redacción como una forma personal de procesar información y como una herramienta para interactuar con su entorno. En la última parte, se enumeran los conceptos y procesos mínimos a los que debería recurrir una educación que respete los procesos evolutivos, afectivos y comunicativos, vinculados con la alfabetización inicial. Resulta de enorme importancia, para entender el problema, la psicogénesis de la lectoescritura: este problema tiene implicancias políticas y económicas, pues un niño que no comprende lo que lee es un niño que estará limitado en sus oportunidades laborales; del mismo modo, una sociedad en vías de desarrollo con niveles deficientes de comprensión lectora, como la del Perú, tendrá complicaciones para insertarse en una economía globalizada.

Investigating the Dialectics of Space
Authors: BELBACHA Mohammed
Published: March 2016

It should be pointedly stated again that nobody is able to escape the condition of spatiality. Space is everywhere; it always surrounds us, people cannot avoid its influence. Our living is extremely conditioned by the notion of spatiality. What is more, our body is considered as the framework of reference for our perception because we always tend to explain spatial qualities or the position of objects in relation to our body. An object that you come to see from a close space is unquestionably different from another which is situated afar. An entrance to an enclosing area certainly impacts our perceptions and definitely shapes our conceptions. Following these two instances, it is manifest that movement and space are tightly linked to each other, with each one reciprocally affecting the other. This only sustains the conspicuous importance and influence of travel which basically comprises these two constituents: movement and space.
The role of coating in the ice-proof aviation technology

On your auto windshield, ice is a disturbance. Be that as it may, on a plane, a wind turbine, an oil apparatus or electrical cable, it can be out and out unsafe. Furthermore, uprooting it with the strategies that are accessible today—normally concoction softening operators or work serious scrubbers and mallets—is troublesome and costly work. That could soon change on account of a sturdy, economical ice-repellent covering created by University of Michigan specialists. Flimsy, clear and marginally rubbery to the touch, the splash on equation could make ice slide off gear, planes and auto windshields with just the power of gravity or a delicate breeze. This could have real ramifications in businesses such as vitality, delivery and transportation, where ice is a consistent issue in frosty atmospheres.
