Authors: Silva Lorena Emanuelle Da Silva Santos , Oliveira Jones Sidnei Barbosa de , Evangelista Taiana Jambeiro , Suto Cleuma Sueli Santos , Mascarenhas Nildo Batista
Published: June 2017

O manejo inadequado dos Resíduos produzidos em Serviços de Saúde (RSS) representa um risco potencial à saúde dos trabalhadores, população e meio ambiente, sendo necessária a implantação de Planos de Gerenciamento de Resíduos de Saúde bem elaborados. Objetivou-se comparar o manejo/gerenciamento dos resíduos nas unidades de atenção básica (UBS) e unidades hospitalares (UH) através de uma revisão sistemática da literatura. Os dados foram coletados nas bases BDENF e LILACS, analisados 21 artigos publicados entre 2006 a 2015. Os resultados evidenciam que nas UBS e nas UH não se manejam adequadamente os resíduos produzidos, conforme preconizado pela legislação vigente; necessita-se assim implantar ações de educação permanente para que trabalhadores da saúde e da higienização possam manejar os RSS adequadamente; o número de acidentes laborais durante o manejo é comum e a etapa da segregação é fundamental no gerenciamento. Conclui-se que nas UBS e UH a implantação do plano de gerenciamento não atende às recomendações legais, já que ambos não realizam o manejo correto dos resíduos, principalmente na etapa de segregação. A não realização desta etapa dificulta o manejo adequado e eficiente dos RSS nas fases seguintes, com implicações diretas na saúde das pessoas e no meio ambiente.

ABSTRACT

         The present research seeks to find out a model of criminal case resolution of traffic accidents causing death in Traffic Directorate of Yogyakarta (DIY) Police Department through either criminal justice system or mediation. Socio-legal research or non-doctrinal research has been used for this research. The research location is located in the Traffic Directorate of Yogyakarta Police Department. The research data use primary and secondary data. The results of this research indicate that in Traffic Directorate of DIY Police Department criminal case of traffic accidents causing death is resolved through criminal justice system with a record of ordinary examination. It is in accordance with the Decree of Indonesian National Police Number 15 of 2013 regarding Procedures for Handling Traffic Accident. Meanwhile, mediation is never used to resolve such case since there exists no legal framework. The article, therefore, suggests that revision of the Decree should be made. The criminal case resolution of traffic accidents causing death should fall into two forms, namely willful misconduct and negligence. A case with willful misconduct should be resolved through criminal justice system, while  that negligence is resolved through mediation.

Near Surface Characterization Using VP/VSand Poisson's Ratio from Seismic Refractions
Authors: Alam Md. Iftekhar , Jaiswal Priyank
Published: June 2017

This paper shows that the ratio of compressional- and shear-wave velocities (VPand VS, respectively) better characterize the near-surface than individual velocity models. In a proof-of-concept experiment, vertical and tangential data were acquired along a 23 m, 2D profile containing two well-documented utility pipes with 0.76 m diameter and 1.5 m burial depth. First arrivals of both datasets were inverted using a regularized tomography algorithm. The inverted VPand VSimages, which fit their respective datasets within the noise level, were smooth with no clear anomalous structure at the pipe locations. In the VP/VSratio image, however, the pipe locations appear as zones with high ratio values (>1.8). A nearby zone of low (<1.5) VP/VSratio was interpreted as a backfilled void. These results suggested that carefully conducted P- and S-refraction tomography can provide quick and effective near-surface reconnaissance.

Published: June 2017

The U.S. military has developed and currently uses composite material munitions. These composite munitions are typically comprised of carbon fiber and, because of their low electrical conductivity, have a much lower electromagnetic induction signature, which makes them difficult to detect using traditional metal detecting methods. The term intermediate electrically conductive (IEC) is used to describe these lower conductivity materials, with conductivity, σ, typically in the range 10 < σ < 105 S/m. The electromagnetic induction (EMI) relaxation response of carbon fiber munitions peaks in the low megaHertz range (<15 MHz), but above 100 kHz. Thus, detecting and characterizing these munitions for remediation on military ranges is problematic using available geophysical EMI sensors. This paper describes initial efforts in the development of a prototype frequency-domain EMI sensor with the goal of extending the measurement frequency range to 15 MHz.

Published: June 2017

A vibration-sensitive, Distributed Acoustic Sensor (DAS) array, using fiber-optic cables, was deployed in a triangularly shaped geometry on the frozen surface of Lake Mendota in Madison, Wisconsin, USA. The purpose of the array and testing program was to analyze the DAS response and to utilize the high spatial density of the distributed array for system response characterization in a well-constrained, small, surface array. A geophone array was also deployed to provide a reference system. The design of the array allowed us to assess the response of DAS with respect to distance from the seismic sources, the degradation of the response with length of the cable, the directivity of the fiber response with respect of the direction of the particle motion, and the quality of the signal with respect to cable type. The DAS array was examined for different cable constructions and orientations relative to the source propagation direction. Tight-buffered and loose-tube fiber-optic cable constructions were used, with both having good signal responses when well-coupled to the ice. In general, the tight-buffered cable was better suited for DAS applications. Directional sensitivity of the DAS was also inspected for several directions of wave propagation and particle motion. The results showed that the strongest DAS signals were recorded when the direction of the fiber was oriented parallel to the direction of particle motion. Finally, the DAS and geophone data sets were examined together to qualitatively determine, in conjunction with established DAS best practices, how the high spatial density offered by DAS could improve results over traditional point sensor arrays in certain situations.
Practical Techniques for Enhancing the High-Frequency MASW Method
Authors: Lu Zhiqu
Published: June 2017

For soil exploration in the vadose zone, a high-frequency multi-channel analysis of surface waves (HF-MASW) method has been developed. In the study, several practical techniques were applied to enhance the overtone image of the HF-MASW method. They included (1) the self-adaptive MASW method using a variable sensor spacing configuration, (2) the phase-only MASW method, and (3) a nonlinear acoustic technique. To demonstrate the capability of these techniques, a HF-MASW test was conducted, which consisted of a small shaker operated in chirp mode with three gapped frequency bands and a geophone array with a variable spacing configuration. The overtone images obtained from (1) full spreadlength, (2) self-adaptive spreadlength, (3) full-spectra analysis including magnitude and phase spectra, and (4) phase-only spectrum analysis MASWs, respectively, were compared in each frequency bands. The results revealed the enhanced dispersive images by the HF-MASW using the self-adaptive and phase-only with the variable spacing configuration technique. The study also demonstrated the nonlinear acoustic technique by means of harmonic generation to increase the measurable frequency range of dispersion curves. It is worthy to mention that these techniques can also be applied to the conventional MASW method using controlled seismic vibrators, such as vibroseis.
Prediction of the Liquid Viscosity of Characterized Crude Oils by Use of the Generalized Walther Model
Authors: Ramos–Pallares F.. , Lin H.. , Yarranton H. W. , Taylor S. D.
Published: June 2017

A predictive but tunable model for the liquid viscosity of characterized crude oils was developed by use of the generalized Walther correlation (Walther 1931; Yarranton et al. 2013). The crude oils are each characterized into maltene pseudocomponents and a single C5-asphaltene component. The viscosity model requires two pseudocomponent parameters (A and B), two whole-oil parameters (δ1 and δ2), and binary-interaction parameters. The asphaltene parameters were determined experimentally and fixed for all cases. Correlations were developed for the maltene-pseudocomponent parameters and the binary-interaction parameters. The required data are the absolute temperature, pressure, the C5-asphaltene content, the specific gravity (SG) and molecular weight (MW) of the oil, and the boiling-point distribution of the maltenes. The SG and MW distributions of the maltenes are also required, but are generated from existing correlations. The proposed model predicted the viscosity of five western Canadian and two Colombian bitumens; three American, one Mexican, one Venezuelan, and one European heavy oil; and also a conventional oil from the Middle East with an overall average deviation of 57%. Tuning to a single viscosity data point with a single tuning parameter reduced the overall deviation to 8%, close to the 4% deviation obtained when the model was fitted to the data.
Adsorption of Antimonate by Kaolinite
Authors: Essington Michael , Stewart Melanie , Vergeer Kalyn
Published: June 2017

Core Ideas

Sb(V) adsorption by kaolinite is pH and ionic strength dependent, with adsorption decreasing with increasing pH and ionic strength.

Sb(V) adsorption is hysteretic in acidic systems, but reversible in alkaline.

Adsorbed Sb(V) generates a downward shift in the isoelectric point and an upward shift in the point of zero net proton charge.

Phosphate decreases Sb(V) adsorption, but the influence of sulfate is minimal.

The macroscopic findings indicate that Sb(V) is retained by innersphere in acidic and outersphere in neutral to alkaline systems.

The environmental fate and behavior of antimony (Sb) is controlled by adsorption processes at the solid–solution interface of surface‐reactive solids. One such solid is kaolinite, which bears the aluminol (≡AlOH) surface functional group. The objectives of this study are to characterize antimonate [Sb(V) in the Sb(OH)6– species] adsorption by kaolinite as a function of pH, ionic environment, and competing ligands (PO4 and SO4); to describe the reversibility of the adsorption and the influence of adsorbed Sb(V) on the surficial properties of kaolinite; and to develop predictive surface complexation models. The results of this study show adsorbed Sb(V) is at a maximum in strongly acidic suspensions, and retention decreases with increasing pH and ionic strength. Adsorption is hysteretic in pH < 5 suspensions, becoming reversible with increasing pH. The point of zero net proton charge (PZNPC) increases from 4.5 in KNO3 to 5.6 in KSb(OH)6. Correspondingly, the isoelectric point decreases from 4.5 in KNO3 to <3 in KSb(OH)6. The macroscopic findings indicate that Sb(V) is retained by a combination of inner and outersphere mechanisms, with the former dominating in acidic suspensions. The inclusion of SO4 had little impact on the retention of Sb(V); however, PO4 reduced Sb(V) retention. The inclusion of both inner‐ and outersphere complexes in the triple layer surface complexation model (TLM) provided an adequate description of the Sb(V) adsorption envelopes. Further, the TLM successfully predicted ligand retention in competitive systems without re‐optimization.

Published: June 2017

Core Ideas

Reliable surface representation is important for porosity analysis inside soil cores.

High‐resolution soil surface maps are drawn from computed tomography scanning data.

The moving‐window procedure presented here deals with artifacts and soil cavities.

High‐resolution mapping of the soil surface provides insight regarding gas and water transport at the soil–atmosphere interface and biogeochemical reactions occurring in soil pores connected to the atmosphere. A new procedure for high‐resolution soil mapping was tested in undisturbed cores (15‐cm diameter) with images constructed from X‐ray computed tomography (CT) scanning. Our procedure includes detecting boundaries at the soil–air interface, edge cleaning, and removal of artifacts by use of a moving window with optimized size. We tested the procedure on three undisturbed soil cores from an agricultural field: (i) without introduced earthworms vs. in which earthworms of (ii) smaller (Aporrectodea turgida Eisen) or (iii) larger (Lumbricus terrestris L.) size were introduced and resided for 28 d. Soil surface maps were produced at a scale of 0.35‐ by 0.35‐mm pixels, with gray tones reflecting lower to higher elevation. This work has implications for describing pore connectivity and interpreting greenhouse gas fluxes from the soil.
Useful Drainage Estimates Obtained from a Large‐Scale Soil Moisture Monitoring Network by Applying the Unit‐Gradient Assumption

Useful daily drainage estimates obtained from soil moisture measurements at 60 cm.

Annual drainage estimates indicate potential recharge rates to groundwater aquifers.

Uncertainty in the drainage estimates was relatively high at sites with high precipitation.

Groundwater supplies ~20% of global freshwater withdrawals, and accurate information regarding groundwater recharge rates is needed for sustainable groundwater management. Recharge rates are often limited by the rates of drainage from the soil profile, which are influenced by soil moisture conditions. Soil moisture monitoring has expanded dramatically in recent decades with the advent of large‐scale networks like the Oklahoma Mesonet, which has monitored soil moisture statewide since 1996. Using those data with site‐specific soil hydraulic properties and a unit‐gradient assumption, we estimated daily drainage rates at 60 cm for 78 sites for up to 17 yr. Our working hypothesis was that these drainage rates are indicative of potential groundwater recharge rates. Mean annual drainage rates ranged from 6 to 266 mm yr−1, with a statewide median of 67 mm yr−1. These rates agreed well with prior recharge estimates for major Oklahoma aquifers. To provide a further independent check on our results, drainage was modeled using HYDRUS‐1D for four focus sites across 17 yr. Soil‐moisture‐based drainage rates and HYDRUS‐1D drainage rates agreed to within 10 mm yr−1 at the drier two sites but had discrepancies of > 150 mm yr−1 at two sites with > 1000 mm yr−1 precipitation. Simulations also showed that for a semiarid site the unit‐gradient assumption was likely violated at the 60‐cm depth, highlighting the need for deeper soil moisture monitoring. Despite these limitations, this simple method for estimating drainage through long‐term soil moisture monitoring shows unique potential to provide valuable information for hydrology and groundwater management.
Perspectivas de la educación desde la tecnología y era digital: ¿paradigmas de transformación cultural?
Authors: Cuevas Silva Juan María
Published: June 2017

La educación ha ocupado un puesto privilegiado en la cultura, le ha sido dedignada la tarea de transmitir los conocimientos, costumbres culturales, historia, tradiciones, informaciones, entre otras. Por mucho tiempo se le confió al educador la responsabilidad de poseer el conocimiento y transmitirlo con autoridad incuestionable. De la misma manera, las bibliotecas y las escuelas se convirtieron en lugares sagrados donde se guardaba y contenía todo el conocimiento. Los libros eran los contenedores sacros del saber y del conocimiento y para que una persona accediera a él tenía que asistir a la escuela o ir hasta la biblioteca. Estas designaciones culturales se han visto alteradas y cambiadas por el surgimiento de la Internet, por el posicionamiento que ha ido ganando la red y el ciberespacio, pero sobretodo por los avances rápidos y acelerados de la tecnología, especialmente en lo que tiene que ver con los medios rápidos de comunicación. La educación está al filo de la navaja en estos procesos, se está viendo afectada y exigida por dichos avances. La escuela y el educador han perdido su lugar sagrado, ya no poseen el saber, el conocimiento; están sufriendo el impacto de la deslocalización e interlocalización de los saberes. En el presente artículo se hace una reflexión sobre la educación, desde los retos que imponen la tecnología como paradigma neo-cultural y algunas propuestas de la era digital. La educación no le puede dar la espalda a la tecnología, pero tampoco puede aceptar ciegamente todas sus propuestas e influjos, por esta razón es importante que el educador y la educación inicien un proceso de cambio: pasar del uso instrumental de la tecnología al uso estructural, de tal manera que se favorezca la formación de la persona humana con sentido vital y profundidad epistemológica.

The Buss-Perry Aggression Questionnaire: construct validity and gender invarianceamong Argentinean adolescents
Authors: Reyna Cecilia , Sanchez Anahi , Lello Ivacevich Maria Gabriela , Brussino Silvina
Published: June 2017

The Aggression Questionnaire (Buss & Perry, 1992) is one of the most used instruments to assess aggression; it includes 29 items grouped into 4 factors. Furthermore, a reduced version of 12-item has been proposed (Bryant & Smith, 2001), and it has also been examined by several researchers. Nevertheless, Latin-American samples have rarely been included. In this study, exploratory and confirmatory models were evaluated among a sample of adolescents from Cordoba, Argentina (N = 371). Moreover, internal consistency and gender invariance were examined. A 2-factor structure resulted in the exploratory analysis, while 2- and 4-factor (short and long versions) structures showed acceptable fits in confirmatory analysis. In general, internal consistency was acceptable, and gender invariance was supported. Implications and limitations are discussed.
Outliers detection and treatment: a review.
Authors: Cousineau Denis , Chartier Sylvain
Published: June 2017

Outliers are observations or measures that are suspicious because they are much smaller or much larger than the vast majority of the observations. These observations are problematic because they may not be caused by the mental process under scrutiny or may not reflect the ability under examination. The problem is that a few outliers is sometimes enough to distort the group results (by altering the mean performance, by increasing variability, etc.). In this paper, various techniques aimed at detecting potential outliers are reviewed. These techniques are subdivided into two classes, the ones regarding univariate data and those addressing multivariate data. Within these two classes, we consider the cases where the population distribution is known to be normal, the population is not normal but known, or the population is unknown. Recommendations will be put forward in each case.
Standardization in psychological research.
Authors: Fischer Ronald , L. Milfont Taciano
Published: June 2017

The term standardization has been used in a number of different ways in psychological research, mainly in relation to standardization of procedure, standardization of interpretation and standardization of scores. The current paper will discuss the standardization of scores in more detail. Standardization of scores is a common praxis in settings where researchers are concerned with different response styles, issues of faking or social desirability. In these contexts, scores are transformed to increase validity prior to data analysis. In this paper, we will outline a broad taxonomy of standardization methods, will discuss when and how scores can be standardized, and what statistical tests are available after the transformation. Simple step-by-step procedures and examples of syntax files for SPSS are provided. Applications for personality, organizational and cross-cultural psychology will be discussed. Limitations of these techniques are discussed, especially in terms of theoretical interpretation of the transformed scores and use of such scores with multivariate statistics.
The effect of financial crises on stock market liquidity across global markets
Authors: D. Kaya Halil , Ngah S. Engkuchik Engku
Published: June 2017

In this study, using a widely available market liquidity measure, the “turnover ratio”, the authors test for market liquidity contagion during the four financial crises that occurred between 1997 and 1999: The Thai crisis, the Hong Kong crisis, the Russian crisis, and the Brazilian crisis. It is found that while the liquidity levels decreased in approximately half of the sample markets, in the remaining half, the liquidity levels actually improved. The Granger causality tests show that while there is almost no evidence of causality (in both directions) before each crisis, during each crisis, approximately half of the pairwise tests were significant. The results show that most of these causalities are reverse feedback effects from the non-crisis-origin markets to the crisis-origin market. Therefore, it is concluded that the more crucial phenomenon during these crises is the “reverse feedback effects” rather than the liquidity contagion itself.
Perspectives of accumulation of funds in the accumulative pension insurance system of Ukraine
Authors: Berezina Svitlana
Published: June 2017

The pension system existing in Ukraine does not correspond to the modern requirements of society and needs radical reforms in which the main focus should be on the introduction of a mandatory accumulative pension system. It is shown that accumulation of funds in accumulative pension system (APS) requires complex calculations. A model for accumulation of funds in the accumulative pension insurance system used in this paper makes it possible to determine a set of interrelated parameters – insurance premium rates, reasonable insurance periods, the desired rates of profitability, the required amount of savings, investment potential of accumulative pension system, etc. The amount of funds in accumulative pension insurance system depends not only on the basis of insurance (number of payers of insurance premiums), the amount of contributions (rate and object) and (primarily) on the term of beginning of payments of insurance premiums, the coefficient of profitability of invested funds and guarantees of their safety at all stages of functioning of the accumulative system. The analysis has shown that it is necessary: to cover all people employed in the economy with accumulative pension insurance; a rate of contributions should be determined not only by wages, but also by income; prior to the introduction of accumulative pension system – to create the necessary infrastructure, to develop a legal framework, to organize the management of accumulative funds, to solve the issues related to the protection of funds from the risks of losses. The beginning of introduction of the accumulative system should be postponed till 2020.

Published: June 2017

This study investigates the impact of various resources, specifically both tangible and intangible ones, together with capabilities of Malaysian listed firms, on their performance. This empirical study attempts to enrich the understanding of the resources-performance relationship, which is one of a business process within the firm, as well as filling the gaps in present knowledge. Firms, which are not able to develop and sustain their performance, are associated with the vulnerability and adverse performance result, especially during various periods of economic crisis (three sub-periods of major shocks, i.e., The Volcker Shock (Commodities Shock) of early 1980s, Asian Financial Crisis of the late 1990s, and the Global Financial Meltdown of 2008). Hence, this research intends to explore which resources matter the most to firm profitability and its success. Drawing upon the combination of Donabedian’s structure process outcome and resource-based theories of the firm a conceptual framework is developed. Data for the study were collected from a sample of 250 publicly traded companies listed on Bursa Malaysia (MYX). In order to achieve the objective and response to the study question, partial least square and regression analysis are applied. Findings indicate that tangible resources have no impact, while intangible resources have positive and significant impact on firm performance. In addition, results show that efficient allocation of intangible resources is crucial to achieving good performance.
Positive impact of international companies on development of knowledge economy
Authors: Polyakov Maxim
Published: June 2017

In recent years, all economically developed countries of the world experience formation of knowledge economy as the highest stage of postindustrial economy development. International companies, basing their activity on accumulation of human capital according to the principles of innovativeness, scientific nature, continuity and progressiveness, play an important role in activation of this process. Owing to global nature of their activity it influences all spheres of human life in the world, improving it, as well as having an adverse impact (enhancement of poverty in some regions of the word, environment pollution, etc.). Achievement of these conditions of sustainable economic growth is possible just by the way of prevention of the adverse impact, which, among other things, depends on the active social position of the management of international companies. Therefore this paper is aimed at identification of priority focuses of socially responsible activity of international companies. This goal was achieved through generalization of basic program initiatives of the activity of three companies, leading in innovations (Apple, Samsung and IBM). Adoption of the above-mentioned initiatives by other companies of the world as guides while developing their own development strategy has to facilitate the growth of positive effects from enhancement of knowledge economy in the world.

A integração entre o ensino presencial e o virtual, o ensino híbrido, vem sendo foco de estudos no cenário mundial. No Brasil, a normatização da semipresencialidade, pela portaria nº 4.059/2004, permitiu a hibridização do ensino. O objetivo deste estudo é analisar como as universidades federais estão ofertando o ensino híbrido em cursos de graduação presenciais, considerando-se sua regulamentação. O estudo teve abordagem qualitativa com viés exploratório descritivo, no qual foi realizada uma análise documental das regulamentações que autorizam a oferta do ensino híbrido nas universidades federais, bem como um questionário diagnóstico. A análise dos dados indica uma incompreensão acentuada do uso das tecnologias da informação e comunicação e de como elas podem ser apropriadas pelos cursos de graduação presenciais para fomentar a hibridização do ensino.
Performance of nitrogen removal in attached growth reactors with different carriers
Authors: Le H. T. , Jantarat N. , Khanitchaidecha W. , Ratananikom K. , Nakaruk A.
Published: June 2017

Two waste materials, concrete and sponge, were used as biomass carriers in the attached growth reactor in a nitrogen wastewater treatment system. The nitrogen removal performance was compared to a control reactor using commercial carrier material. The highest nitrogen removal efficiency, 87%, was found in the sponge reactor, with the concrete reactor showing 82% efficiency ahead of the commercial reactor of 76%. A thick biofilm developed on the fiber of the sponge carrier, with the biomass increasing from 270 g-VSS/m3-carrier to 1,000 g-VSS/m3-carrier. For the concrete carrier, biomass was observed on the concrete cracks and also as a biofilm on the surface. The maximal biomass was 630 g-VSS/m3-carrier. The content of the biomass agglomerated in the commercial carrier was 310 g-VSS/m3-carrier. Nitrification and denitrification simultaneously occurred to remove nitrogen in the sponge and the commercial carrier reactor. However, in the concrete reactor, nitrification mainly occurred during the aeration phase and denitrification occurred in the non-aeration phase. These results demonstrate that the sponge was the best carrier, with high nitrogen removal efficiency, dense biomass and tolerance to shock loading. The simplicity inherent in the system design together with good performance make it suitable for use in wastewater treatment systems.

Authors: Bulut Ömer Uğur , Karluk Sadık Rıdvan
Published: June 2017

In our study, the selected financial liberalization and pre-crisis indicators which is inspired by the work of Kaminsky, Lizondo and Reinhart known as KLR approach is analyzed. For Turkish economy, the completion of the financial liberalization process in the time interval after 1989, the effects of shock, causality relationship and interact with each of these indicators is surveyed through the VAR model and Toda-Yamamoto test. The purpose of this study to show that financial liberalization indicators of
hot money movements, real interest rates and credit growth triggered the crisis which were experienced in Turkey after 1989 by adversely effecting the pre-crisis indicators. In addition to this purpose, the most effective indicators of financial liberalization on pre-crisis indicators will be determined for Turkish economy. According to VAR model and Toda-Yamamoto causality test, the negative impact on the pre-crisis indicators, description of these indicators percentage and the causality relationship of hot money movements and real interest rates are more than the credit growth. The results will give ideas on policy makers in Turkey about the effectiveness of the financial liberalization in economic crises.

Authors: Singh Yadvendra , Mishra S.K. , Lai K.K.
Published: June 2017

In this paper, we consider a nonsmooth semi-infinite multiobjective
programming problem involving support functions. We establish sufficient
optimality conditions for the primal problem. We formulate Mond-Weir type
dual for the primal problem and establish weak, strong and strict converse
duality theorems under various generalized convexity assumptions. Moreover,
some special cases of our problem and results are presented.
Estado de salud e intención de volver a Estados Unidos en migrantes mexicanos: ¿evidencia de un sesgo de retorno selectivo?
Authors: Bojórquez Chapela Ietza , González Fagoaga Eduardo , Guillén López Tonatiuh

El objetivo de este trabajo ha sido explorar la asociación entre la intención de permanecer en México (versus la intención de volver a Estados Unidos), con los indicadores del estado de salud de los migrantes que entraron a México por la frontera norte en 2010, para lo cual se utilizó información de la Encuesta de Migración en la Frontera Norte (Emif-N). Fue menor la probabilidad de que desearan volver a Estados Unidos quienes manifestaron peor estado de salud, en comparación quienes reportaron mejor estado de salud.
Norovirus y coinfección con parásitos intestinales en pacientes con diarrea en el Hospital San Rafael de Tunja, Colombia
Authors: Jaimes-Bernal Claudia Patricia , Ramírez-Rueda Román Yesid , Rodríguez-Mesa Marta Beatriz
Published: June 2017

Introducción. La gastroenteritis aguda se considera un problema de salud pública. Entre los agentes responsables de esta enfermedad están los virus, de los cuales los más frecuentes son el rotavirus, el astrovirus, el adenovirus y el norovirus. Objetivo. Determinar la prevalencia de norovirus y de coinfección con parásitos intestinales, en la materia fecal de pacientes que consultaron al Hospital San Rafael de Tunja. Métodos. Se trata de un estudio cuantitativo, descriptivo y de corte transversal. Se contó con una muestra de 166 individuos y el muestreo fue no probabilístico a conveniencia. La presencia de norovirus se evaluó con un ensayo inmunoenzimático y la de parásitos se determinó por medio del examen coprológico. Los resultados se analizaron con el programa SPPS®, versión 19. Resultados. La prevalencia de norovirus fue de 9,63 % (IC95% 9,3-9,8 %) y la de parásitos intestinales fue de 35,54 % (IC95% 28,2-42,7 %). El rango de edad en el que hubo más resultados positivos para norovirus, fue el de 0 a 14 años, con mayor frecuencia en menores de cinco años. En siete muestras (4,21 %) se presentó coinfección del virus y parásitos. Se reportó coinfección con Blastocystis spp. Conclusiones. La prevalencia de norovirus en la población estudiada resalta la importancia de determinar esta causa infecciosa viral, al menos en los episodios asociados a una enfermedad diarreica aguda con dificultades en el diagnóstico diferencial. La coinfección de norovirus y Blastocystis spp., podría explicar la presencia de enfermedad diarreica aguda en estos pacientes. Se propone incluir la determinación de norovirus como causa de diarrea en niños. Palabras clave: gastroenteritis, norovirus, epidemiología, ensayo de inmunoadsorción enzimática, prevalencia
Ejercicio terapéutico para desarrollar cambios posturales en estudiantes universitarios
Authors: Rondón-Villamil Yudy Alexandra
Published: June 2017

Introducción. La buena postura consiste en la alineación del cuerpo con una máxima eficacia fisiológica y biomecánica, que minimiza los esfuerzos y tensiones a los que se somete el sistema de soporte a causa de la gravedad. Los ejercicios terapéuticos alivian los síntomas, mejoran la función y mantienen o frenan el deterioro de la salud, acciones que se reflejan en una adecuada postura. Objetivo. Describir los cambios en la postura después de un programa de intervención con técnicas de ejercicios terapéuticos, tales como estiramientos analíticos, miofasciales, autoposturas de rehabilitacion postural global, ejercicios propioceptivos, técnica de Klapp y método de McKensie®, en 17 sujetos de 18 a 23 años que cursaban el quinto semestre del programa de Fisioterapia de la Universidad de Boyacá. Material y métodos. Se llevó a cabo un estudio descriptivo, de serie de casos, en que se analizaron los cambios en los componentes posturales, después de la implementación de un programa de ejercicio terapéutico, de media hora o más al día, cinco veces por semana, durante 16 semanas. Se utilizó la carta de simetría postural como instrumento para evaluar la postura en sus diferentes planos, previo consentimiento informado de los sujetos participantes. Resultados. Se evaluaron los cambios en la alineación de la cabeza, simetría de los hombros, caída de los dedos, rotación del tronco, simetría en las rodillas, y base de sustentación y apoyo. Conclusiones. Mediante el ejercicio terapéutico basado en técnicas utilizadas en forma secuencial según su complejidad, que se inicia con estiramientos analíticos, seguidos de estiramientos miofasciales, ejercicios propioceptivos, técnica de Klapp y método de McKenzie, y culmina con autoposturas de rehabilitación postural global, se producen cambios posturales. Palabras clave: postura, ejercicios de estiramiento muscular, propiocepción, fisioterapia, rehabilitación
La vitamina A: reguladora de la espermatogénesis
Authors: López Laura Ximena Ramírez , Quiroga Carlos Fernando Prada
Published: June 2017

La vitamina A es esencial para el desarrollo de las células germinales masculinas, la fertilidad y la espermatogénesis normal. El ácido retinoico, metabolito activo de la vitamina A, es necesario para la maduración de las espermatogonias y la entrada correcta de las células germinales en la profase meiótica en los testículos. La expresión de Stra8, fundamental en la meiosis y la espermatogénesis normal, está directamente relacionada con la disponibilidad del ácido retinoico. Este artículo se centra en el proceso de espermatogénesis y la interacción de la vitamina A con el ciclo seminífero, a fin de explicar la relación existente entre la disminución de los aportes de vitamina A, y las alteraciones presentadas en la espermatogénesis de humanos y algunos animales. También, se consideran los efectos de otros genes implicados en la síntesis de la vitamina A, su transporte y su degradación, y se discuten los posibles mecanismos celulares que pueden verse afectados por la falta de señalización de la vitamina A, en particular, la regulación del ciclo celular y la interacción célula-célula, puntos críticos para la espermatogénesis normal. En esta revisión de los 42 artículos científicos más relevantes del tema, se hizo una búsqueda de información en bases de datos como Science Direct, Scielo, Medline, Redalyc y Pubmed, durante los meses de enero a abril de 2014. Se encontró que en diversos estudios se ha demostrado que se puede controlar in vitro la proliferación de células germinales y su diferenciación, y además, que un deficiente consumo de vitamina A estaría relacionado con la disminución de la fertilidad masculina. Palabras clave: vitamina A, espermatogénesis, bloqueadores de espermatogénesis, meiosis, ácido retinoico, testículos.
