Reduction of scum production in a modified UASB reactor treating domestic sewage
Authors: Pereira J. O. , Rocha J. M. , Pinto W. B. C. C. , Moreira C. T. S.
Published: May 2019

The scum accumulation inside gas–solid–liquid separators (GSL) is one of the main limitations of upflow anaerobic sequencing batch (UASB) reactors during treatment of domestic sewage. Although this type of reactor can be equipped with devices that periodically remove scum, this solution has been proved to be very expensive in addition to being inefficient when discharging procedures are not correctly performed. The main goal of this study was to investigate the performance of a modified UASB reactor concept with a GSL separator which promotes continuous scum discharge to the settling compartment. Furthermore, this proposal was compared with a conventional UASB reactor which was used as control. Both reactors in demo-scale were fed with domestic wastewater and scum production was measured. The results demonstrated volumetric reduction of 50%, and 75% reduction in the mass of total solids in the modified reactor. Additionally, the amount of biogas recovered from the modified reactor was higher than the amount that the control reactor recovered. Therefore, the proposed modification has been proved to be effective, bringing new possibilities to the GSL project.
The Experiences Of Infection And Prevention Control Nurses (Ipcns) In Cultivating Hand Hygiene
Authors: Fitriyah Erna Tsalatsatul , Dwidiyanti Meidiana , Dwiantoro Luky
Published: May 2019

Healthcare-Associated Infections (HAIs) are infections that patients get while undergoing treatment and medical procedures in the hospital or other healthcare facilities after more than 48 hours. Improving the quality of hand hygiene practices can reduce pathogen transmission that causes HAIs. Infection and Prevention Control Nurses (IPCNs) as the pioneers of infection prevention and control should play an active role in cultivating hand hygiene in the hospital environment. Unfortunately, until the present time, there is evidence that IPCNs have not played their roles optimally in making hand hygiene a culture in the hospital. This study aimed to explore the experiences of IPCNs in cultivating hand hygiene at the inpatient wards in a regional hospital in Semarang, Indonesia. This study used a qualitative research design with a phenomenological approach. The samples were recruited using purposive sampling technique, consisting of three IPCNs as the main participants, and one Infection Prevention and Control Officer (IPCO) and three Infection Prevention and Control Link Nurses (IPCLNs) as the triangulation participants. Data were collected using semi-structured in-depth interviews and analyzed using the content analysis. The results revealed two themes. First, the appropriate education implementation and its documentation are important to provide an adequate understanding of medical and non-medical staffs, patients and families so that they are willing to perform hand hygiene properly. Second, the implementation of hand hygiene requires complete infrastructures and facilities, proper monitoring and evaluation system, as well as appropriate role models and motivation so that hand hygiene can become a positive culture. This study concludes that IPCNs have positive and negative experiences while trying to cultivate hand hygiene. IPCNs understand and agree that their ability to provide proper education and sensitivity to the factors affecting the implementation of hand hygiene can improve the people’s understanding and compliance with hand hygiene. In the end, hand hygiene will eventually become one of the positive cultures in the hospitals.

Published: May 2019

Fifty percent of end-of-life patients spend the last time of their life in the Intensive Care Unit (ICU). End of life conditions have an impact on the psychological, physical, social, and family environment that affect the quality of life of other families. Family welfare will have an impact on care outcomes, hospitalization time, and patient stressor levels. The purpose of this study was to explore the life quality of end of life patient's family in ICU. This research used qualitative method with descriptive phenomenology approach. Sampling was done by purposive sampling technique with 9 participants. data were collected through in-depth interviews and analyzed using the Colaizzi method.  The data validity was designed to meet the principle of triangulation of researchers and theory. The results showed 7 dimensions of life quality of end of life patient's family of physical health (fatigue, sleep disorder, headache, decreased appetite), mental health (anxiety, sadness, hope of improved family health condition), spiritual health (acceptance), health social (social support), daily life (daily life adjustment), financial health (financial burden), and environment (opportunity to get information, family infrastructure).  This study concludes that end of life condition of critical patients impacts on the 7 dimensions of family life quality. Nurses should pay attention to the family life quality because it affected the condition of the patient  and family as the care service unit.

Feasibility and Acceptability of a Mobile Technology Intervention to Support Postabortion Care (The FACTS Study Phase II) After Surgical Abortion: User-Centered Design (Preprint)
Authors: Gill Roopan Kaur , Ogilvie Gina , Norman Wendy V , Fitzsimmons Brian , Maher Ciana , Renner Regina
Published: May 2019

BACKGROUND

Human-centered design is a methodology that applies an iterative participatory process that engages the end-user for whom an innovation or intervention is designed for from start to end. There is general evidence to support the use of human-centered design for development of tools to affect health behavior, but specifically for family planning provision. This study is part two of a three-phase study that uses a user-centered design methodology which uses the findings from Phase I to design, develop, and test a digital health solution to support follow-up after an induced surgical abortion.

OBJECTIVE

The objectives for this study were to: (1) develop a Web-based intervention based on preferences and experiences of women who underwent an abortion as measured in the formative phase of the Feasibility and Acceptability of a Mobile Technology Intervention to Support Postabortion Care Study; (2) conduct usability testing of the intervention to determine user-friendliness and appropriateness of the intervention; and (3) finalize a beta version of the Web-based intervention for pilot testing.

METHODS

The study design was based on the “development-evaluation-implementation” process from the Medical Research Council Framework for Complex Medical Interventions. This study is in Phase II of III and is based on user-centered design methodology. Phase I findings demonstrated that women engage with technology to assist in clinical care and they preferred a comprehensive website with email or text notifications to support follow-up care. In Phase II we collaborated with family planning experts and key stakeholders to synthesize evidence from Phase I. With them and a development partner we built a prototype. Usability testing was completed with 9 participants using a validated System Usability Scale. This was then used to refine the intervention for Phase III pilot study. This study was approved by the local Ethics board.

RESULTS

We developed a comprehensive Web-based tool called myPostCare.ca, which includes: Post-Procedure Care, Emotional Well-Being Tool, Contraception Explorer, Sexual Health, Book an Appointment, and Other Resources. Additionally, over the course of a month after the procedure, automatic email notifications were sent to women as a form of virtual follow-up support, directing them to myPostCare.ca resources. The Web-based tool was refined based on usability testing results.

CONCLUSIONS

This study demonstrated that user-centered design is a useful methodology to build programs and interventions that are women-centered, specifically for abortion care.

Authors: Anggiratih Endang , Putra Agfianto Eko
Published: May 2019

Ship identification on satellite imagery can be used for fisheries management, monitoring of smuggling activities, ship traffic services, and naval warfare. However, high-resolution satellite imagery also makes the segmentation of the ship difficult in the background, so that to handle it requires reliable features so that it can be identified adequately between large vessels, small vessels and not ships. The Convolutional Neural Network (CNN) method, which has the advantage of being able to extract features automatically and produce reliable features that facilitate ship identification. This study combines CNN ZFNet architecture with the Random Forest method. The training was conducted with the aim of knowing the accuracy of the ZFNet layers to produce the best features, which are characterized by high accuracy, combined with the Random Forest method. Testing the combination of this method is done with two parameters, namely batch size and a number of trees. The test results identify large vessels with an accuracy of 87.5% and small vessels with an accuracy of not up to 50%.

Published: May 2019

Time series prediction aims to control or recognize the behavior of the system based on the data in a certain period of time. One of the most widely used method in time series prediction is ARIMA (Autoregressive Integrated Moving Average). However, ARIMA has a weakness in determining the optimal model. firefly algorithm is used to optimize ARIMA model (p, d, q). by finding the smallest AIC (Akaike Information Criterion) value in determining the best ARIMA model. The data used in the study are daily stock data JCI period January 2013 until August 2016 and data of foreign tourist visits to Indonesia period January 1988 to November 2017.Based on testing, for JCI data, obtained predicted results with Box-Jenkins ARIMA model produces RMSE 49.72, whereas the prediction with the ARIMA Optimization model yielded RMSE 49.48. For the data of Foreign Tourist Visits, the predicted results with the Box-Jenkins ARIMA model resulted in RMSE 46088.9, whereas the predicted results with ARIMA optimization resulted in RMSE 44678.4. From these results it can be concluded that the optimization of ARIMA model with Firefly Algorithm produces better forecasting model than ARIMA model without Optimization.

Authors: Ohnishi Tsuyoshi , Kimachi Miho , Fukuma Shingo , Akizawa Tadao , Fukuhara Shunichi
Published: May 2019

Background and objectives

Almost half of patients on dialysis demonstrate a postdialysis serum potassium ≤3.5 mEq/L. We aimed to examine the relationship between postdialysis potassium levels and all-cause mortality.

Design, setting, patients, & measurements

We conducted a cohort study of 3967 participants on maintenance hemodialysis from the Dialysis Outcomes and Practice Patterns Study in Japan (2009–2012 and 2012–2015). Postdialysis serum potassium was measured repeatedly at 4-month intervals and used as a time-varying variable. We estimated the hazard ratio of all-cause mortality rate using Cox hazard regression models, with and without adjusting for time-varying predialysis serum potassium. Models were adjusted for baseline characteristics and time-varying laboratory parameters. We also analyzed associations of combinations of pre- and postdialysis potassium with mortality.

Results

The age of participants at baseline was 65±12 years (mean±SD), 2552 (64%) were men, and 96% were treated with a dialysate potassium level of 2.0 to <2.5 mEq/L. The median follow-up period was 2.6 (interquartile range, 1.3–2.8) years. During the follow-up period, 562 (14%) of 3967 participants died, and the overall mortality rate was 6.7 per 100 person-years. Compared with postdialysis potassium of 3.0 to <3.5 mEq/L, the hazard ratios of postdialysis hypokalemia (<3.0 mEq/L) were 1.84 (95% confidence interval, 1.44 to 2.34) in the unadjusted model, 1.44 (95% confidence interval, 1.14 to 1.82) in the model without adjusting for predialysis serum potassium, and 1.10 (95% confidence interval, 0.84 to 1.44) in the model adjusted for predialysis serum potassium. The combination of pre- and postdialysis hypokalemia was associated with the highest mortality risk (hazard ratio, 1.72; 95% confidence interval, 1.35 to 2.19, reference; pre- and postdialysis nonhypokalemia).

Conclusions

Postdialysis hypokalemia was associated with mortality, but this association was not independent of predialysis potassium.
La cuestión de Europa y el (re)surgimiento del antisemitismo o nuevo antisemitismo. Antecedentes y situación actual
Authors: García Arévalo Tania María
Published: May 2019

Las nuevas realidades europeas son un factor clave para entender el antisemitismo, un concepto que ha adoptado nuevas formas en los siglos XX y XXI y que ha sido favorecido por la llegada de inmigrantes a Europa, la emergencia de los partidos de derecha y el antisionismo. El objetivo de este artículo es ofrecer un recorrido histórico mediante el que puedan observarse su naturaleza y transformaciones hasta llegar al nuevo antisemitismo que es al que asistimos hoy día. Partimos de la premisa de la existencia de este fenómeno actualmente, con la hipótesis de trabajo de que en los últimos años efectivamente ha habido un resurgimiento e incremento de éste, como lo revelan las cifras presentadas en distintos informes y en nuevos
contextos, como las redes sociales. El principal hallazgo es que nos encontramos con un nuevo antisemitismo que deja a un lado la confrontación personal, sin eliminarla, para moverse en la esfera tecnológica amparada por el anonimato.
Observaciones sobre encuentros entre hermenéutica, pragmática y análisis del discurso
Authors: Nadal Palazón Juan
Published: May 2019

En este artículo se presenta una revisión de conceptos de las tradiciones de la hermenéutica, la pragmática y el análisis del discurso con el objetivo de mostrar que sus planteamientos pueden ser vistos como complementarios, si bien a menudo se considera que estos ámbitos no son claramente diferenciables e incluso inconexos o irreconciliables. Se muestra que, aunque procedan de distintas corrientes de pensamiento, la hermenéutica, la pragmática y el análisis del discurso en realidad tienen en común el objeto de estudio, la finalidad y el punto de partida, razón por la cual no es extraño que compartan matrices conceptuales, independientemente de sus evidentes diferencias en alcance, precisión y aplicabilidad.

Authors: Sharma R. K. , Shah Dr.H. S. , Gohel Dr. J.K. K
Published: May 2019

As a matter of fact, surgery (cholecystectomy or gall bladder removal) is the most common form of treatment for cholelithiasis (gallstones). However, the fact that surgically removing gallstones requires the removal of an entire organ has led to a growing interest in non-surgical treatments for gallstones. Besides alleviating symptoms, treatment for gallstones is necessary to avoid a progression that can result in severe conditions such as acute cholelithiasis. But so far as the medical management of cholelithiasis is concerned, it is not up to the mark in modern healing system. Although ursodiol or chenodiol in the form of oral bile acid pills, extracorporeal shock-wave lithotripsy (ESWL), contact dissolution therapy [injecting a solvent known a Methyl tertiary-butyl ether (MTBE) into the gallbladder to dissolve the gallstones], Percutaneous Cholecystostomy are good non-surgical measures, their roles are either limited or these are not free from adverse effects. Obviously, there is an urgent need of help from Alternative therapy to counter these difficulties. This article is a step in the direction of making an availability of a safe and effective non-surgical management of cholelithiasis to the ailing mankind.

PDV: VIOLÊNCIA E HUMILHAÇÃO
Authors: Heloani Roberto
Published: May 2019

Intenta-se, neste artigo, discutir as formas utilizadas no encobrimento das relações sociais que determinam os suicídios no trabalho. Nas últimas décadas, vários casos de suicídio laboral ocorreram em nosso país no setor bancário. No Brasil, tivemos casos emblemáticos na década de 1990: um banco público, que possuía uma cultura de respeito aos direitos trabalhistas e empática aos seus funcionários, viu-se sujeito de um amplo processo de reestruturação no qual a ferramenta principal consistia em um PDV (Programa de Desligamento Voluntário). A direção da instituição alegou que necessitava “modernizar-se” e para isso fazia-se necessário “renovar seu quadro de funcionários”. Para os recalcitrantes em permanecer na instituição, “procedimentos motivacionais” foram adotados e “estímulos” utilizados, tal como repreender o funcionário na presença do “amigo cliente”, xingamentos, desqualificações, isolamentos etc. Deste modo, o artigo aponta para a necessidade de se conhecer melhor as causas dos suicídios no trabalho.
SITUAÇÃO DE QUASI-UBERIZAÇÃO DOS DOCENTES PAULISTAS?
Authors: Venco Selma
Published: May 2019

O propósito deste artigo é analisar as formas de contratação de professores praticadas no governo do estado de São Paulo. O texto apoia-se na realização de pesquisa documental e qualitativa, esta última por meio de entrevistas semiestruturadas junto aos professores licenciados na referida rede. A nova vaga da uberização do trabalho expressa a ausência de: contrato, jornada, rendimentos assegurados e direitos a ele vinculados, e, nesse sentido, debatem-se as medidas do poder público próximas às oriundas das empresas inscritas na gig economy. Constata-se que esses profissionais, aqui denominados “sem-sem”, vivenciam uma situação de quasi-uberização, posto que contam com alguns poucos direitos vinculados ao trabalho.
AÇÃO SINDICAL NA ARGENTINA E NO BRASIL: UMA ANÁLISE A PARTIR DOS CASOS DA CUT E DA CGT NO ALVORECER DO SÉCULO XXI
Authors: Colombi Ana Paula , D’Urso Lucila
Published: May 2019

Neste artigo, tem-se como objetivo investigar em que medida a atuação da CUT e da CGT alterou a agenda do trabalho dos governos petistas e kirchneristas entre 2003 e 2014 e, ainda, indagar se suas práticas, seus discursos e seus resultados podem ser interpretados como um processo de revitalização ou recuperação sindical no Brasil e na Argentina. Em primeiro lugar, analisam-se as transformações no mercado e nas relações de trabalho. Num segundo momento, mapeiam-se as ações das centrais frente aos principais embates em torno dos aspectos centrais da relação de emprego. A pesquisa mostra que as reivindicações da CUT e da CGT se concentram majoritariamente no campo econômico, sem lograr maiores mudanças nos elementos que versam sobre as condições de trabalho, suas modalidades de contratação e a jornada laboral. Ambas as centrais privilegiaram uma atuação no âmbito institucional, o que limitou a capacidade de o movimento sindical reverter o processo de flexibilização das relações laborais, permitindo problematizar a tese da revitalização sindical nesses países.

Políticas públicas de informação e Inteligência Coletiva: os desafios e as possibilidades para a democratização da informação
Authors: Franco Angela Halen Claro , Carvalho Angela Maria Grossi , Santos Plácida Leopoldina Ventura Amorim da Costa
Published: May 2019

O paradigma social da informação apresenta desafios múltiplos para o tempo do conhecimento interativo da Ciência da Informação, principalmente no que diz respeito ao aproveitamento da inteligência coletiva nos ambientes digitais. Nesse contexto, a inteligência coletiva se manifesta como proposta que visa o aproveitamento das habilidades individuais em prol do desenvolvimento de um Espaço do saber. A dotação de infraestrutura tecnológicas e competências digitais para a inserção dos indivíduos nesse espaço requer a instauração de políticas públicas eficientes para a área da informação. Sendo assim, por meio da análise exploratória e descritiva, pretende-se aproximar as políticas de informação à inteligência coletiva. Observou-se que os ideais de democratização da informação são comuns aos dois campos, e que a definição de políticas públicas de informação consistentes é alternativa viável para a realização do Espaço do saber e, por conseguinte, para a valorização da inteligência coletiva.

Reflexões sobre a genealogia dos regimes de informação
Authors: González de Gómez Maria Nélida
Published: May 2019

Trata da conceituação de regimes, tal como concebida nos estudos de relações internacionais, com importante expressão na literatura anglo-saxônica, com algumas contribuições originais e críticas de autores da Europa continental. É retomada a análise do conceito de regime de informação política, de Sandra Braman (2004, 2006), que reposiciona questões de informação no campo da política, mas não em suas manifestações institucionais mais formais. Destaca o papel dos mecanismos regulatórios que operam sem estarem totalmente inseridos nas esferas das políticas públicas e estaduais. São situações em que novos usos de tecnologias computacionais e redes digitais geram vácuos regulatórios equivalentes aos encontrados por vezes nas relações internacionais, e que hoje afetam diferentes países e regiões nos níveis global e local. Essa reconstrução dos usos do conceito de regime nas relações internacionais, nas ciências políticas e na ciência da informação também expõe para reflexão alguns traços dos contextos históricos de sua formulação.

Esta pesquisa trata-se de um estudo de caso do tipo descritivo, que busca analisar as teses e dissertações que abordam as interconexões entre as áreas da gestão de documentos (GD) e da gestão da informação (GI), no âmbito dos programas de pós-graduação relacionados à área de conhecimento da Ciência da Informação, no Brasil. Parte de discussões teóricas acerca da interdisciplinaridade entre Arquivologia e Ciência da Informação, mais especificamente sobre a possibilidade de diálogos entre gestão de documentos e gestão da informação. Entre os resultados, constatou-se que há poucas pesquisas realizadas sobre o tema, revelando a necessidade de se desenvolver estudos que aprofundem o assunto. Em relação ao conteúdo apresentado pelos pesquisadores, a perspectiva integrada foi unânime nas discussões de todos os trabalhos. Para alguns estudiosos, a GD está subordinada à GI, enquanto que para outros, essa relação não se trata de uma hierarquia, mas de áreas que se complementam. Por fim, concluiu-se que a GD e a GI são duas áreas que possuem ramos de atuação específicos, mas que podem se complementar, a fim de garantir a ocorrência dos fluxos informacionais de maneira eficaz.
Economic Consequences of the AOCI Filter Removal for Advanced Approaches Banks
Authors: Kim Sehwa , Kim Seil , Ryan Stephen G.
Published: May 2019

We examine economic consequences of U.S. bank regulators' phased removal of the prudential filter for accumulated other comprehensive income for advanced approaches banks beginning on January 1, 2014. The primary effect of the AOCI filter is to exclude unrealized gains and losses on available-for-sale securities from banks' regulatory capital. We predict and find that, to mitigate regulatory capital volatility resulting from the filter removal, advanced approaches banks increased the proportion of investment securities classified as held-to-maturity, thereby limiting their financing and interest rate risk management options, and they decreased securities risk, thereby reducing their interest rate spread. We further predict and find that these banks borrow more under securities repurchase agreements potentially collateralized by held-to-maturity securities and reduce loan supply owing to their reduced financing options, and that they increase loan risk to mitigate the decrease in their interest rate spread.

Additive manufacturing design rules are different from those of conventional fabrication techniques. These allow geometries that would not be possible to achieve otherwise. One example of application is the integration of functional parts as part of the manufacturing process. Conceivable applications range from mechanical functions like integration of moving parts or thermodynamic functions, for example, cooling channels or incorporation of electric circuits for electrical functionalization [J. Glasschroeder, E. Prager, and M. F. Zaeh, Rapid Prototyping J. 21, 207–215 (2015)]. Nevertheless, the potential of functional integration using powder-bed processes is far from being exhausted. The present approach addresses the generation of inner cavities and internal structures of titanium-based parts or components by the use of selective laser melting. This paper focusses on the investigation of voids and cavities regarding their capabilities to add new functions to the material. To this end, comprehensive characterization is performed using destructive as well as nondestructive testing methods. These include 3D scanning, computed tomography, and surface roughness measurements as well as microscopic analysis. Voids and cavities were filled with different thermoplastic materials, followed by the qualitative assessment of the mold filling and resulting material properties. Finally, applications are derived and evaluated with respect to the field of lightweight design or damping structures.

A köpeny eredetű xenolitok közül ritkaságnak számító, modális metaszomatózison átesett, flogopit- és apatit-tartalmú amfibol-gazdag peridotitok is előkerültek. Jelen munkában egy ilyen, gazdagodott xenolit komplex fluidumzárvány vizsgálatát mutatjuk be. Fluidumzárványokat ortopiroxénben és amfibolban azonosítottunk. Utóbbi ásványban ritkán őrződnek meg köpenyfluidumok zárványai, ezért vizsgálatuk egyedi lehetőséget nyújt a köpenyben vándorló fluidumok megismerésére. Az elsődleges és álmásodlagos zárványok összetételét petrográfiai elemzések után mikrotermometriai és Raman-mikrospektroszkópiai mérések segítségével határoztuk meg.

Az ortopiroxének zárványainak folyadék fázisában a nagy sűrűségű (~1 g/cm3) CO2 a domináns komponens (>95 mol. %), ami mellett H2O-t (<3,5 mol. %) és N2-t (<0,2 mol. %) is kimutattunk. A fluidumzárványokban azonosított szilárd fázisok leányásványok, magnezitből és anhidritből állnak. Amfibolok zárványaiban szintén CO2 a leggyakoribb komponens (>98 mol. %), ami mellett H2O-t (<1,2 mol. %), N2-t (<0,1 mol. %) és a vízben oldott SO42--t azonosítottunk. A szilárd fázisok különböző karbonátokból (magnezit, Na-tartalmú dawsonit, nahkolit és nátrit) és szulfátokból (anhidrit, Na-tartalmú thenardit-burkeit) álló ásványegyüttest alkotnak. A klór-mentes, Na+ és SO42--tartalmú fluidösszetétel egyedinek tekinthető köpenykörülmények között. A fluidum forrása egy illó-gazdag olvadék lehetett, amelyben az amfibol (valamint alárendelten flogopit és apatit) kristályosodása során feldúsultak az illók (C-O-N-S), Na+, HCO3- és SO42-, amelyek csapdázódtak a keletkező amfibolban.

La Educación. Un factor determinante de la estabilización del desarrollo local sostenible
Authors: Venegas Gina , La Calle Juan José , Proaño Carlos
Published: May 2019

La educación es un instrumento esencial en el desarrollo local, pero no puede convertirse en el único elemento responsable del mismo. Actualmente se habla de la influencia de las competencias educacionales como aliciente de un mejoramiento del plano económico social. Se empieza a endosar la responsabilidad de un futuro éxito económico-social-político de la región y del país al proceso educativo enmarcado en un modelo pedagógico que facilite la solución de problemáticas socioeconómicas. Un primer problema que se plantea ante la relación entre desarrollo local y educación, es ¿Cuál es la pedagogía más adecuada a implementar para lograr un desarrollo local? El objetivo de este trabajo fue identificar la pedagogía adecuada que permita despegar con el desarrollo local. Hoy en día hay una verdadera selva pedagógica difícil de aplicar de manera clara en los procesos educativos; desde las instancias gubernamentales las políticas emanadas se proyectan a buscar un mejoramiento de la calidad educativa con proyección a contribuir con el desarrollo sostenible del país, pero las diferentes escuelas pedagógicas son difíciles de adaptar. Se aplicó una encuesta para determinar la pedagogía más utilizada por los docentes en el aula y como modelo pedagógico institucional y se realizó un análisis documental. El resultado muestra la preferencia docente para desarrollar su actividad académica y se observa claramente que la educación es solo un medio y que necesita adoptar una corriente pedagógica que vaya de la mano con el desarrollo o el postdesarrollo local. Se propone un modelo aplicado a establecimientos educativos franceses.

Authors: Pardo Bernardoni Matias
Published: May 2019

La presente investigación tiene como propósito la aplicación del Modelo Moori-Koenig-Yoguel para determinar el perfil de la inserción externa y conducta exportadora a Pymes de del sector químico de Venezuela, la cual se basa enla fundamentación teórica de Moori-Koenig-Yoguel (1995), Carvajal (2014), para la variable inserción externa y por Estrada y Heijs (2005) y Gatto (1995) para conducta exportadora, la misma tuvo un enfoque metodológico positivista, fue de metodología empleada fue de tipo analítica, con un diseño, no experimental transeccional-descriptiva de campo. La población estuvo conformada por tres empresas seleccionadas al azar con tres unidades de información correspondiendo a Gerentes de las tres empresas, debido a que se trabajó bajo un muestreo de tipo incidental. Para la ejecución de la mismase diseñó un instrumento identificado como “EXPORTES” contentivo de ambas variables el cual fue sometido a juicio de experto por tres especialistas y luego se obtuvo la confiabilidad de este bajo el método Alpha de Cronbach, arrojando una confiabilidad 0.90. Los datos obtenidos fueron interpretados a través de la aplicación de estadísticas no paramétricas de indicadores medidos, mostrando la existencia de debilidades a nivel de la dinámica exportadora, tipología y perfil básico para la variable inserción externa. Por parte de la variable conducta exportadora las debilidades se encuentran a nivel de los indicadores inserción externa y proactividad exportadora. Partiendo de esta información, se pasó a diseñar una propuesta teórica con lineamientos para hacerle frente a la problemática evidenciada en la investigación.

The article discusses an attempt to evaluate the ergonomic vibration environment of selected technical sources used in various technological processes. The scope of the tests included measurement of general vibrations in the plane of the seat carrier and local vibrations occurring on the steering wheel of selected technical sources. The tests were carried out in two trucks and in a vibratory road roller. The measurements were carried out in 10 repetitions for each technical measure. On the basis of the obtained measurements, the mean value of vibration acceleration, effective vibration acceleration and peak vibration acceleration as well as the weighted vibration acceleration value were determined. The obtained results were confronted with the applicable standards. It was noted that the daily vibration exposure of general action in the case of road roll works in the horizontal direction was 1,11 m∙s-2 and exceeded the limit values for men and women in the working age. In the case of other vehicles tested, there was no exceedance of the permissible mechanical vibration value in any of the analyzed directions and do not pose a threat to the employee.
