Rehabilitación pulmonar en el adulto mayor con neumopatía crónica obstructiva y/o interstical en el Hospital Nacional de Geriatría y Gerontología, Dr. Raúl Blanco Cervantes de mayo del 2012 a junio del 2013
Authors: Araya Aguilar Karla 
Published: January 2019

El objetivo principal del estudio es describir la respuesta de los adultos mayores con neumopatía obstructiva y/o intersticial a un programa de rehabilitación pulmonar en sus diferentes componentes. Se define rehabilitación pulmonar como un programa de ejercicios de entrenamiento y al menos uno de los siguientes componentes: educación, apoyo psicosocial y nutricional, como ha sido definido en otros estudios. Métodos: Estudio observacional, descriptivo y retrospectivo. Resultados: De los 12 pacientes, solo nueve finalizaron por completo el programa. La disnea, según la escala del mMRC, mejoró en el 42% y se mantuvo sin cambios en el 58%. Hubo mejoría significativa en la caminata de seis minutos (p = 0,009), en la PIMáx en el 83%, con un promedio de 16,6 kPa (16,9 cmH2O); el índice de BODE en el 100% de los pacientes (p=0,015). En éste índice, la mayor mejoría se dio en los componentes de disnea (p = 0,007) y la C6M (p = 0,009). En el cuestionario de Saint George, el 75% obtuvo una respuesta positiva al programa, con mayor respuesta en los síntomas. No hubo mejoría en el FEV1 o FEV1/FVC. La resistencia muscular de extremidades superiores e inferiores aumentó. Ninguna variable tuvo correlación significativa con edad, sexo y FEV1. Conclusiones: La rehabilitación pulmonar en personas adultas mayores con neumopatía obstructiva y/o intersticial evidencia una respuesta estadísticamente significativa en la caminata de C6M, índice de BODE, fuerza muscular de músculo respiratorios y resistencia muscular en extremidades superiores e inferiores. Con mejoría, pero sin significancia estadística en la escala de disnea del mMRC, y cuestionario de Saint George. No se obtuvieron cambios en los parámetros espirométricos.
STUDY OF THE PROCESS OF CALIBRATION OF CONFECTIONERY SUNFLOWER SEEDS
Authors: Shevchenko I. , Aliiev E. 
Published: January 2019

The aim of the research was to make the mechanical and technological process of calibrating confectionery sunflower seeds with a vibrating sieve more effective by giving reasons for its rational methodical and technological parameters. The study of calibration of confectionery sunflower seeds had two stages: numerical simulation and experimental verification. For the first stage, the physical models for numerical simulation (in the STAR-CCM+ software package) of the movement of seeds with a vibrating sieve were: k-ɛ model of separated flow turbulence, gravity field, Van der Waals real gas model, discrete elements model, multiphase interaction model. The second stage, experimental verification of the models obtained, was carried out on a calibration machine (sizer) OKMF. Sieves of three types were selected: perforated sieves, rod sieves, and precision sieves (produced by laser cutting). The numerical simulation of moving the confectionery sunflower seeds with a vibrating sieve has allowed determining how changes in total concentration and productivity depend on the way of the input of the seeds, the sieve angle, the vibration frequency and vibration amplitude of the sieve. To make the seed separation process effective, the vibrating sieve is to operate with the maximum productivity equal to the seed input (1,202 kg/h), with the maximum total seed concentration (10.83%). Experimental studies of moving the seeds of confectionery sunflower with vibrating sieves of different types (perforated screens, rod sieves, and precision sieves) have allowed establishing how changes in total concentration, productivity, and consumed power of the calibrating machine depend on the seed input, sieve angle, and frequency of vibrations of the sieve. To make the seed separation process effective, the vibrating sieve is to operate with the maximum productivity equal to the seed input (perforated screens – 1.116 kg/h, rod sieves – 1,518 kg/h, precision sieves – 1,781 kg/h), with the following total seed concentrations: perforated sieves – 14.54%, rod sieves – 12.45%, precision sieves – 10.41%, and power P (perforated sieves – 0.24 kW, rod sieves – 0.30 kW, precision sieves – 0.35 kW) consumed by the calibrating machine must be minimum. Precision sieves (produced by laser cutting) have the best characteristics of their performance (q=1781 kg/h) and quality (θ=10.41%). For this, the frequency of their vibrations should be 5.9 Hz, and their angle should be 5°.
Alexandra Nickerson, The Privacy Paradox
Authors: Nickerson Alexandra A 
Published: January 2019

Privacy is as complex a concept as it is ubiquitous. But Vanderbilt law and history professor Sarah Igo bravely takes on the challenge of chronicling the history of this mutable, yet fundamental American value. In doing so, she demonstrates the irreconcilable trade-off between privacy and exposure, both of which can be liberating and oppressive in their own right. Readers will be impressed by the depth and the breadth of this tome, as Igo examines privacy’s role in fields as disparate as law, psychometrics, philosophy, and technology. As a result, they will come away with a profound, new consciousness of being “known” to the government and to all facets of society. Despite the feelings of vulnerability this awareness may induce, Igo’s book gives us the knowledge, perspective, and foresight to revisit our own privacy debates with agency and determination. As known citizens, the future of privacy is in our hands.
A New Longitudinal Examination on the Relationship between Teaching Style and Adolescent Depression
Authors: Yao Zhuojun , Luh Weiming 
Published: January 2019

Guided by the theoretical framework of Baumrind’s parenting style, this study aimed at providing a
better understanding of the relationship between teaching style and adolescent depression. The
panel data is from the Taiwan Educational Panel Survey (N=654). Findings showed that the effect of
teaching style on adolescent depression had different pattern accross junior and senior high school
students. And there is interaction effects between teaching style in junior and senior high school.
Authoritarian teaching style played a more significant role for junior high students, and this effect
can last especially among those whose perception of teaching style is authoritarian and authoritative
in high school. And permissive teaching style was more important in senior high stage, it could
decrease the levels of depression especially for those who perceived teaching style is indifferent and
authoritarian in junior high school. Implications for future research were discussed.
Análisis de falla operacional de un sistema hidroneumático en instalación hospitalaria
Authors: Monteagudo Yanes José Pedro , Jiménez Borges Reinier 
Published: January 2019

Introducción: El trabajo presenta el estudio de la falla operacional de un sistema hidroneumático destinado al suministro de agua a una institución hospitalaria.
Objetivo: Determinar la o las causas de interrupción del suministro de agua del sistema hidroneumático a la edificación.
Metodología: Se trazó la característica hidráulica del sistema de tubería y se comparó con la característica hidráulica del sistema hidroneumático, comprobando que satisfacía plenamente las solicitudes de carga y flujo requeridas por la edificación. Dada la presencia de ruidos y vibraciones en la tubería de succión se realizó la comparación del NPSH requerido con el NPSH disponible, determinando que el actual diseño de la tubería de succión es la causa de la falla del sistema hidroneumático.
Resultados: Se proponen tres variantes de modificación al diseño de la tubería de succión que eliminan el fenómeno de la cavitación. Ello evita poner en operación una bombea auxiliar que incrementa el consumo energético en 8760 kWh/año con un costo de 1839,6 $/año y la inseguridad en el servicio de agua.
Conclusiones: El equipo hidropresor seleccionado cumple satisfactoriamente los requerimientos de la instalación, exceptuando el diseño de la tubería de succión donde el NPSH disponible es inferior al NPSH requerido para caudales superiores a 900 l/min, apareciendo el fenómeno de la cavitación y provocando la salida de servicio del sistema.

Published: January 2019

Introducción: El presente artículo muestra el diseño e implementación de un sistema anticolisión para invidentes usando redes neuronales evolutivas.
Objetivo: Presentar la implementación de redes neuronales evolutivas en un sistema guía para invidentes en la detección de obstáculos estáticos y en movimiento.
Metodología: La metodología empleada se basa en la creación de redes neuronales artificiales a partir del algoritmo genético cooperativo coevolutivo (AGCC), este se encarga de estructurar, modificar y entrenar las redes neuronales. Para ello utiliza la matriz de definición de red (MDR). Para la elaboración de una MDR se toma como base un cromosoma “parte del algoritmo genético”. Una vez este realizada la MDR se crea una red neuronal artificial para luego ser entrenada.
Resultados: El programa realizó varias redes neuronales generando en cada ejecución 10 cromosomas, que al ser entrenados con el AGCC y aplicando la cooperatividad, se obtuvieron las mejores redes neuronales anticolisión teniendo en cuenta un tiempo definido, funcionando efectivamente para la detección de obstáculos estáticos y en movimiento.
Conclusiones: En el sistema anticolisión para invidentes se observó la eficacia de las redes neuronales en dar una respuesta, detectando objetos tanto estáticos como en movimiento proporcionando seguridad al invidente, evitando colisiones con estos.
Small bowel volvulus post gastric bypass
Authors: Ferris Baillie W. C. 
Published: January 2019

Small Bowel Volvulus (SBV) is an uncommon cause of Small Bowel Obstruction (SBO), which can be difficult to diagnose. However, it is very important to recognise and intervene in a timely manner due to the high risk of bowel ischemia. Unfortunately, SBV does not always have clinical features that differentiate it from other causes of mechanical obstruction. The most reliable investigation appears to be Computed Topography (CT) scan with around 50% of patients displaying the classic ‘whirl’ sign on CT. However, many remain undifferentiated SBO patients. Any of these patients who have any clinical or radiological suspicion of bowel ischemia, should be considered for surgery, as delays in diagnosis of bowel ischemia are associated with an increased risk of morbidity and mortality. In this case reported, author detailed a 55year female who presented with SBV had a CT scan which showed the classic ‘whirl’ sign and thus had timely surgical intervention and an uncomplicated recovery. Her history was significant for a subtotal colectomy, and a Rouxeny gastric bypass. This case highlights the importance of early recognition of SBV and also carries a reminder to consider rare causes of abdominal pain in patients who have had previous bariatric surgery. They have altered anatomy and thus are at increased risk of internal hernia and volvulus including SBV.

<p>Este artigo busca trazer elementos para compreender como famílias residentes em territórios vulneráveis se relacionam com a escolarização de seus filhos. Para tanto realizou pesquisa de inspiração etnográfica junto a 12 famílias moradoras de um bairro de periferia da cidade de São Paulo. As mães foram as principais informantes. A metodologia de análise dos dados consistiu na construção de retratos sociológicos de cada uma das mães e numa análise transversal desses retratos. Os resultados permitem concluir que as mães pesquisadas atribuem um grande valor à escolarização de seus filhos, embora o grau do envolvimento com essa escolarização seja dependente do grau de vulnerabilidade das famílias. Permitem também caracterizar esse tipo de envolvimento, os significados atribuídos à escola, e a natureza e os tipos de esforços realizados para assegurar a permanência na escola e uma escolarização mais longa, limitada, porém, em geral, pela conclusão do ensino médio.

<p>Este trabalho, de natureza exploratória, tem por objeto a construção do espaço das tomadas de posição e argumentos sobre o debate a respeito do processo de centralização e padronização curricular no país, por meio de uma Base Nacional Curricular Comum. Tem também por objetivo examinar as relações entre as tomadas de posição e argumentos e a posição social dos indivíduos entrevistados - agentes que participam do debate público sobre o tema, porém atuando em diferentes campos do mundo social. Assim construído, o objeto de pesquisa se insere no quadro da sociologia de inspiração bourdieusiana, de modo central em sua teorização sobre os campos sociais. Para realização da investigação, foram efetuadas entrevistas com 103 nomes que em geral participam do debate educacional (academia, sociedade civil, educação básica, sindicatos, gestão pública), de todas as regiões do país, entrevistados, com base num roteiro semiestruturado, entre o final de 2013 e início de 2014.

Maternidad en red. Comunidades digitales de crianza como espacios de deconstrucción de la identidad en la maternidad = Motherhood on the web. Online parenting communities as forums for deconstructing identity in motherhood
Authors: Imbaquingo Pérez María Isabel 
Published: January 2019

Resumen. El presente artículo explora la función de las comunidades digitales de crianza en el ejercicio de la maternidad, enmarcado dentro del concepto general de “maternaje”. Para lograr este objetivo se realizó un análisis del proceso discursivo de las integrantes del Círculo de Crianza Vertiente de Amor y Vida, que consistió en la confrontación de los mensajes generados en el grupo virtual y diversos conceptos y perspectivas teóricas sobre las transformaciones y “contradicciones culturales” de la maternidad y la forma en que las nuevas tecnologías intermedian y modifican la manera en que las madres interactúan en la actualidad. El análisis reveló que la comunidad virtual cumple una función en la forma en que las mujeres deconstruyen su identidad y el lugar de pertenencia en la maternidad. De la misma forma, se estableció que la sociedad, a través del discurso, somete a las mujeres a una comunicación de doble vínculo que impide una comprensión clara de la maternidad; la comunidad digital puede ofrecer oportunidades de evitar o superar este doble vínculo. Finalmente, el estudio determinó que existen mujeres que se encuentran en un estado liminal entre el ejercicio de la maternidad y su reconocimiento social como madres. La comunidad virtual puede permitir a las mujeres concluir con ese estado e incorporarse a uno nuevo que valida la maternidad.Palabras clave: maternidad, discurso, crianza, comunidad digital, doble vínculo, rito de pasaje Abstract. This article explores the role of online parenting communities in the exercise of motherhood, within the general concept of “mothering”. To achieve this goal, an analysis of the discursive process of the members of the Breeding Circle of Love and Life was carried out, which consisted of the discussion of the messages generated in the online group and various concepts hood and the way in which new technologies influence and change the way mothers interact to­day. The analysis revealed that the online community plays a role in the way women deconstruct their identity and their place within motherhood. In the same way, it was established that so­ciety, through discourse, subjects women to a double bind communication that prevents a clear understanding of motherhood. The online community can offer opportunities to avoid or over­come this double bind. Finally, the study determined that there are women who are in a liminal state between the exercise of motherhood and their social recognition as mothers. The online community can allow women to end that status and join a new one that validates motherhood.Keywords: motherhood, discourse, breeding, online community, Double Bind, rite of passage
