Guatemala: El papel de los medios en el debate público
Authors: Monzón Ana Silvia , García Arenas Linda
Published: January 2019

El artículo plantea brevemente algunas categorías que orientan la exposición, ubicando el concepto de debate u opinión pública centrada en los medios de comunicación y vinculándolo con la historia guatemalteca en las últimas tres décadas. Este período abarca el fin formal del conflicto armado interno hacia 1985, la firma de los Acuerdos de Paz, en 1996, el cual abrió la expectativa de una efectiva democratización de las instituciones, de la ciudadanía y, por supuesto, de los medios de comunicación, hasta entonces muy limitados en el ejercicio de un periodismo investigativo y crítico, y el deterioro de las instituciones estatales que, sobre todo en los últimos cinco años, han empezado a tener impacto en la opinión pública crítica (medios alternativos e independientes) y han reforzado un esquema de colusión entre los intereses partidarios y los medios, el cual ha contribuido a pervertir la democracia en el país.

Primero presenta las implicaciones adversas de las corrientes financieras ilícitas en materia derechos humanos. Luego describe el marco legal e institucional panameño, en particular las obligaciones y compromisos internacionales del país, así como el sector bancario y financiero del país. También se presentan los llamados “papeles de Panamá”, tanto la irrupción del escándalo, las disposiciones adoptadas por el gobierno así como las medidas adicionales que aún resultan necesarias. Se discuten asimismo cuestiones vinculadas al crecimiento económico del país, la desigualdad y los derechos humanos, así como se analizan críticamente las implicaciones de proyectos de infraestructura sobre los derechos humanos de las personas y los grupos en Panamá, incluidos los pueblos indígenas. Luego de las conclusiones se presentan recomendaciones que el autor efectuó al gobierno panameño como Experto Independiente de la ONU luego de su visita al país.
Építészettörténet és építészeti tervezés
Authors: Fehér Krisztina , Krähling János
Published: January 2019

A két világháború közötti magyar építészeti közélet egyik legnagyobb hatású eseménye az 1930-ban Budapesten rendezett XII. Nemzetközi Építészkongresszus volt. A kongresszus programjához kapcsolódóan a Műcsarnokban nemzetközi tervkiállítást, a Műegyetemen pedig hallgatói tervekből készült kiállítást rendeztek. Ez utóbbinak érthető módon eltörpül a sajtóbeli visszhangja a másikhoz képest, az Építészettörténeti és Műemléki Tanszék rajztárának feldolgozásakor azonban egy olyan összefüggő tablósorozat került elő, amelynek egységes, öt nyelven feliratozott grafikája és keltezései is arra utalnak, hogy a Műegyetem kiállítási anyagához tartozhatott. A tablókra kasírozott építészettörténeti rajzok bizonyíthatják, és ekképpen majdhogynem az egyedüli bizonyítékai, hogy a Műegyetemen a tervezésoktatás mellett más tárgycsoportok, így az építészettörténet is bemutatásra került. A tablók fontos adalékot szolgáltatnak az építészettörténet oktatásának két világháború közötti változásairól, a kongresszus és a kiállítások sajtóba leszűrődött visszhangja pedig a 19. században még egységben lévő építészeti tervezés és építészettörténet tovább élő viszonyára utalnak.
CHIVA to spare the small and great saphenous veins after wrong-site surgery on a normal saphenous vein: a case report
Authors: Faccini Felipe Puricelli , Arendt Ani Loize , Pereira Raphael Quintana , Oliveira Alexandre Roth de
Published: January 2019

Abstract CHIVA (Cure Conservatrice et Hemodynamique de l’Insufficience Veineuse en Ambulatoire) is a type of operation for varicose veins that avoids destroying the saphenous vein and collaterals. We report a case of CHIVA treatment of two saphenous veins to spare these veins. The patient previously had a normal great saphenous vein stripped in error in a wrong-site surgery, while two saphenous veins that did have reflux were not operated. The patient was symptomatic and we performed a CHIVA operation on the left great and right small saphenous veins. The postoperative period was uneventful and both aesthetic and clinical results were satisfactory. This case illustrates that saphenous-sparing procedures can play an important role in treatment of chronic venous insufficiency. Additionally, most safe surgery protocols do not adequately cover varicose veins operations. Routine use of duplex scanning by the surgical team could prevent problems related to the operation site.
La efectividad de una ley de protección al servicio de la conservación de un recurso marino: El ejemplo del camarón fantasma Callichirus major (Decapoda, Callianassidae) de la costa de Brasil

Published: January 2019

RESUMEN La mortalidad por pesca ha sido pocas veces estudiada aislando el efecto causado por las capturas. En este estudio se analizó este aspecto usando como modelo biológico al camarón fantasma Callichirus major (Say, 1818), el cual es colectado intensamente en varias regiones de la costa de Brasil. Para ello, la densidad de las galerías y la demografía poblacional de C. major fue analizada en las playas de Gonzaga e Itararé, dos playas contiguas del Estado de São Paulo, Brasil. La playa de Gonzaga fue considerada como control debido a que desde 1992 una ley municipal impide las capturas de C. major, mientras que Itararé fue considerada como tratamiento ya que en este lugar este camarón es recolectado durante todo el año. Los resultados mostraron que la densidad de las galerías y el tamaño de las hembras fueron significativamente mayores en la playa de Gonzaga que en Itararé. En Itararé, la proporción sexual no mostró diferencias significativas de la relación 1:1, lo cual no se ajustó a lo observado en el área sin mortalidad por pesca y al patrón general reportado en otras especies de camarones fantasma del mundo en donde las hembras predominan sobre los machos. El potencial reproductivo fue significativamente menor en Itararé, como efecto del menor número de hembras presentes en esta área sometida a la pesca intensiva de camarones. De acuerdo con una estimativa inicial, un 71% de los individuos murieron por efecto de la pesca en Itararé. Esto hace inviable el sostenimiento ambiental de C. major en esta área dada la actual presión de extracción. La presencia de C. major en la playa de Itararé y probablemente en otras áreas próximas donde es capturada, estaría favorecida por el permanente suministro de larvas procedentes de la playa de Gonzaga, en Santos, que está protegida por ley y fiscalización municipal.

Resumo Objetivo: Mensurar a adesão aos medicamentos imunossupressores em receptores de transplante renal, utilizando a Basel Assessment of Adherence with Immunosuppressive Medication Scale - BAASIS® e descrever as características sociodemográficas, os fatores clínicos em relação aos imunossupressores e os níveis de creatinina. Métodos: Estudo prospectivo, transversal, realizado no período de 2014 a 2015, no Ambulatório Pós-Transplante do Hospital do Rim (complexo hospitalar da Universidade Federal de São Paulo (UNIFESP)). Resultados: Dos 181 participantes, 53,6% eram homens e a idade dos receptores variou de 18 a 74 anos. A Hipertensão Arterial Sistêmica foi o diagnóstico inicial de Insuficiência Renal Crônica em 38,7% dos receptores. Aproximadamente 95% dos receptores relataram que nunca se esqueceram de tomar o medicamento; 58,6% dos pacientes relataram ter aderido totalmente aos imunossupressores e 41,4% não aderiram a uma ou mais das quatro situações avaliadas pelos itens da BAASIS®. Não foi encontrada correlação significativa pelos itens da BAASIS® entre os níveis de creatinina e o escore total. Conclusão: Foi identificado um alto índice de pacientes que não aderiram ao tratamento imunossupressor (41,4%). Não houve correlação significativa entre o nível de creatinina e a idade do receptor no momento do TxR, bem como o tempo após TxR, tempo de separação do imunossupressor e escore total, e escores dos itens individuais da BAASIS®. Esse estudo mostrou que os receptores negros, do sexo masculino, sem uma rede de apoio familiar, obesos e autônomos são mais propensos a não aderir à terapia imunossupressora. A avaliação da adesão do receptor de transplante renal deve ser considerada durante todas as fases das ações do processo de enfermagem que compõem o plano terapêutico após o transplante renal.

Factors and criteria influencing the success of sustainable buildings in Hong Kong
Authors: Tang Ziwei , Ng Shiu-tong Thomas , Skitmore Martin
Published: January 2019

The success of sustainable buildings can help ease the adverse impact of climate change. For this reason, sustainable buildings are becoming a worldwide trend. While defining both critical success factors and success criteria is a prerequisite for achieving sustainable building success, very few studies have been conducted to identify the factors and criteria influencing the success of sustainable buildings. In this study, the structured questionnaire survey method was applied to identify the critical success factors for procuring sustainable building projects and success criteria for measuring the success of sustainable building projects in Hong Kong, China. The results show that top success criteria for sustainable buildings can be grouped into ‘success of traditional project performance’; ‘success of sustainability performance from an environmental, social and economic perspective’; and ‘participants’ satisfaction’. Meanwhile, a factor analysis reveals five principal component factor groups as ‘top management and team competence’; ‘project performance, continuous improvement and stakeholder benefits effectiveness’; ‘life-cycle process management effectiveness’; ‘integrated design and resource management effectiveness’; and ‘budget and risk control effectiveness’. The findings of this paper should help improve understanding of the criteria for measuring sustainable building success and the critical factors leading to the success of these criteria.
Bentonite slurry infiltration into sand: filter cake formation under various conditions
Authors: Xu Tao , Bezuijen Adam
Published: January 2019

Experiments on bentonite slurry infiltration into saturated sand have been carried out in a modified laboratory set-up that provides a hydraulic gradient comparable to real tunnels. Test series 1 investigated the characteristics of mud spurt and filter cake formation during water–bentonite slurry infiltration, before and after removing the external filter cake formed on the original boundary between the slurry and the sand. Test series 2 examined the conditions of filter cake formation during water–bentonite–sand slurry infiltration. The experimental results of series 1 indicate that, in the second infiltration, a new external filter cake will be formed for low concentrations of slurries (40 and 50 g/l), whereas hardly any new external filter cake formed for high concentration of slurry (60 g/l) owing to the formation of an internal filter cake in the sand during the first infiltration. The formation of this internal filter cake meant that the infiltration distance was much smaller for the second infiltration than that in the first for 60 g/l slurry. The experimental results of series 2 with a water–bentonite–sand slurry showed no external filter cake formation, but depth filtration was observed for high-density slurry (1300 and 1500 kg/m3). For low-density slurries (1050 and 1100 kg/m3), a thicker external filter cake, but with a higher permeability, than that in series 1 was observed on the sand surface, because the cake consisted to a large extent of sand particles. Mechanisms of mud spurt and filter cake formation are discussed, with a new solution for mud spurt and the theory of depth filtration.
Desiccation crack formation beneath the surface
Authors: Zhao Budi , Santamarina J. Carlos
Published: January 2019

Desiccation cracks affect all mechanical and conduction properties. Previous studies have investigated the formation of surface desiccation cracks in fine-grained sediments in relation to their compressibility and suction potential. This study explores the formation of internal desiccation cracks in saturated kaolinite specimens consolidated inside self-reactive oedometer cells to reproduce the initial effective stress in buried sediments. X-ray tomography is used to monitor internal processes during consolidation and drying. Images capture the evolution of a perimetric fracture, transverse contraction, volumetric changes in entrained gas bubbles and the development of internal desiccation cracks. Entrained gas bubbles act as nucleation sites. They shrink during loading and early stages of desiccation. Eventually, the gas–water interface penetrates the soil at the bubble surface, pushes particles away, enlarges local pores and facilitates further growth of the internal desiccation crack. While air entry is grain-displacive in soft, fine-grained sediments, it becomes pore-invasive in stiff, coarse-grained sediments and internal desiccation cracks are not expected in silts or sands.

Physicochemical Properties and Oxidative Stability of Milk Fortified with Spray-Dried Whey Protein Concentrate–Iron Complex and In Vitro Bioaccessibility of the Added Iron
Authors: Banjare Indrajeet Singh , Gandhi Kamal , Sao Khushbu , Arora Sumit , Pandey Vanita
Published: January 2019

In the present study, spray-dried whey protein concentrate–iron (WPC–Fe) complex was prepared using a laboratory-scale spray drier under the optimized conditions of inlet temperature 180 °C, flow rate 2.66 mL/min and total solids 15 % with the objective to make iron compatible with food products. In order to remove the free iron from the bound iron, standardised method involving centrifugation and ultrafiltration was employed. Further, the retentate was subjected to spray drying to produce WPC–Fe complex. Milk fortified with WPC–Fe complex (γ(iron)=15 mg/L) showed non-significant difference in heat stability, rennet coagulation time, colour estimation, curd tension, viscosity and sensory attributes as compared to control milk. In vitro bioaccessibility of iron and induction period of the fat from milk fortified with WPC–Fe complex were found to be slightly higher (p<0.05) than that of milk fortified with iron alone. Therefore, milk can be fortified with up to 15 mg/L iron in the form of WPC–Fe complex without significantly affecting its physicochemical properties.

La clave paródico-satírica: una lectura de lo cómico y lo marginado en “Utria se destapa”, de José Félix Fuenmayor
Authors: Gómez Rey Nicolás
Published: January 2019

Este artículo propone una lectura de las relaciones entre lo cómico y lo marginado de Utria (personaje del cuento “Utria se destapa”), al ser él mismo una parodia que reproduce y desarticula un modelo lingüístico: esta imitación y deformación (que toca la sátira) se traduce en la artificialidad y automatismo que configuran al personaje, características que conducen a la risa. En el análisis se relaciona la lectura paródico-satírica de Utria (desde la diégesis del relato y de manera extra-textual) con algunos aspectos del devenir/acontecer literario y social de Colombia, en la primera mitad del siglo xx. El artículo tiene en cuenta las propuestas de Henri Bergson, en La risa (1973), y los aportes de Linda Hutcheon, en “Ironía, Sátira, Parodia. Una aproximación pragmática a la ironía” (1981).

Purpose:to conduct morphohistochemical and immunohistochemical study of arterial unstable atherosclerotic plaques for assessment of the state of smooth muscle cells (SMC) and macrophages.

Materials and methods.The surgical material of the peripheral arteries (femoral, popliteal, external carotid) was obtained from 50 patients aged over 60 years, followed by morphohistochemical, immunohistochemical studies.

Results.Hyperplasia of secretory smooth muscle cells (SMC), and new formation of thin-walled capillary vessels was noted in unstable atherosclerotic plaques. Macrophagic infiltration was detected in the intima of arteries, in places of accumulation of foam cells.

Conclusion.Unstable atherosclerotic plaque is a cellular-intercellular process with the participation of lipids, macrophages, and with predominance of SMC and newly formed vessels.
Population Risk of Ischemic Heart Disease Depending on the Volume of Alcohol Consumption by the Population (ЭССЕ-РФ Study in the Kemerovo Region)
Authors: Maksimov S. A. , Cygankova D. P.
Published: January 2019

Purpose: to assess relationship between the prevalence of cardiovascular risk factors and associated population risk of ischemic heart disease (IHD) alcohol consumption in the Siberian region (Kemerovo Region).

Materials and methods.This work was carried out within the framework of a multicenter epidemiological study “Epidemiology of CardioVascular Diseases in the regions of the Russian Federation” (ЭССЕ-РФ in the Kemerovo region) in 2013. In the final form, the sample size was 1628 individuals aged 25–64 years. We analyzed data on frequency, volume, and type of consumed alcoholic beverages, as well as on the presence of a number of risk factors of cardiovascular diseases and IHD. Alcohol consumption was estimated by the original method, volume of alcohol consumed in a year was categorized as absent (non-drinkers), moderate, medium, and strong. The calculation of the population risk of IHD was carried out according to the author’s methodology, taking into account the prevalence of risk factors and their contribution to the development of IHD.

Results. Prevalence of several risk factors among non-drinkers was significantly different (p<0.05) compared with drinkers with varying degrees of alcohol consumption. In men, there were differences in low physical activity, hypertriglyceridemia, excess weight, education, in women – in anxiety, low physical activity, hypertriglyceridemia, educational qualifications, smoking. In nondrinking men, the additional risk of IHD associated with risk factors was slightly reduced (–1.1 %). In groups of moderate, moderate, and strong alcohol consumption, risk of IHD was higher than the population risk by 2.2 %, 0.7 % and 6.5 %, respectively. In non-drinking women high burden of risk factors accounted for additional risk of IHD (4.5 %). In women with moderate and medium alcohol consumption the risk of IHD was 2.5 and 1.9 %, respectively, lower compared with population risk. Abuse of alcohol in women caused significant increase in the burden of risk factors and, accordingly, was associated with high additional risk of IHD (18.7 %).

Conclusion. Predominantly linear in men and J-shaped in women relationship between prevalence of risk factors and volume of alcohol consumption accounted for analogous tendencies in population IHD risk. Specific for men is close to linear dependence of additional IHD risk on population IHD risk with insignificant variability in non-drinkers, moderate and medial consumers, and with significant growth in alcohol abusers. Women have a J-shaped relationship: in extreme categories (non-drinkiers and alcohol abusers), the risk of IHD is higher than the population risk, while in the middle categories (moderate and medial consumers) it is lower than the population risk.

Authors: Sumin A. N. , Korok E. V. , Korotkevitch A. A. , Kachurina E. N. , Kokov A. N. , Barbarash O. L.
Published: January 2019

Purpose: to assess diagnostic capabilities of single-photon emission computed tomography (SPECT) in the detection of obstructive coronary artery (CA) lesions, depending on the meeting appropriate use criteria. Materials and Methods: We used in this retrospective analysis data from 107 patients with previously diagnosed ischemic heart disease (IHD) or in need to exclude it, who were hospitalized in inpatient departments of the Research Institute for Complex Issues of Cardiovascular Diseases in the period from 2012 to 2015. All patients underwent coronary angiography (CAG) and SPECT (the time interval between the studies did not exceed 3 months) for detection of hemodynamically significant CA stenoses. Patients were distributed into two groups according SPECT imaging appropriateness score: group 1–88 patients with score 7–9 (in whom SPECT imaging was appropriate), group 2–19 patients with score 1–6 (in whom SPECT imaging was uncertain, possibly appropriate, or inappropriate. Results. Clinical signs and symptoms of angina pectoris were predominantly found in group 1 patients (p=0.499). Asymptomatic patients were more likely to be found in group 2 (p<0.001). Group 1 patients commonly had high pretest probability (PTP) (over 90 %, p<0.001), whereas group 2 patients commonly had low PTP (5–10 %, p<0.001). Mean PTP was 77 and 58 % in groups 1 and 2, respectively (p=0.003). According to positive SPECT imaging, significant CA lesions were more often found in group 1 compared to group 2 (31.8 and 10.5 %, respectively, p=0.060). Two- and three-vessel disease prevailed in group 1 (25 % and 14.7 %) according the analysis of prevalence and location of hemodynamically significant CA lesions, although the data did not reach statistical significance (p=0.057 and p=0.073). Stenoses >70 % were more commonly detected in group 1, compared to group 2: in anterior descending artery 52.3 vs. 5.3 % (p<0.001), circumflex artery 35.2 vs. 10.5 %; (p=0.034), right coronary artery 34.1 vs. 10.5 % (p=0.041). The sensitivity in both groups was rather low (40 % vs. 25 %), whereas specificity was 83 % in group 1 and 93 % in group 2. Conclusion. According to clinical examination, patients with IHD and indications for SPECT imaging more often had obstructive CA lesions (63.6 %), than patients with questionable or no indications (21.1 %). However, rate of positive findings during stress tests with SPECT imaging was low in both groups and did not differ significantly (p=0.06). Despite high specificity of SPECT imaging, its sensitivity was low in both groups.

O estudo pretendeu obter informações sobre a técnica de IATF, noções de custos na aquisição de produtos, medicamentos e sêmen a serem utilizados. Sendo assim, buscou-se analisar os aspectos bioeconômicos da IATF para implantação no Sítio Santo Antônio. O método de procedimento utilizado foi o estudo de caso em conjunto com o método comparativo, onde fez-se a comparação do Sistema de Monta Natural com a IATF por meio da Análise de Custo-Benefício (ACB). Os indicadores utilizados foram o Valor Presente Líquido (VPL), a Taxa Interna de Retorno (TIR) e a Relação Benefício-Custo (B/C). O trabalho foi realizado no Sítio Santo Antônio, localizado a 13 Km de Monte Negro e a 55 Km de Ariquemes, onde conta hoje com uma área de 99 alqueires. A realização da pesquisa foi feita através de entrevista com o proprietário do Sítio Santo Antônio, onde se obteve dados do sistema de Monta Natural. Os dados do sistema de IATF foram obtidos com o proprietário do Sítio Peruffo II, através de entrevista, onde o mesmo informou custos com protocolos de IATF. Os dois sistemas apresentam um bom retorno financeiro, contudo, ao se comparar a TIR com a TMA, tem-se que a Monta Natural não apresenta-se rentável.

Identificamos niveles iniciales de riqueza (umbrales de consumo) donde los hogares no demandan depósitos (o no disminuyen sus niveles de endeudamiento). La ausencia de demanda de servicios de depósito (o el uso del crédito sólo para estabilizar consumo) impide que la inclusión financiera impacte los ingresos del hogar. Cuando el umbral de consumo es rebasado, la riqueza del hogar todavía debe aumentar hasta alcanzar el umbral adopción. Durante esta transición, los servicios financieros son una herramienta de administración de riesgo. Cuando el nivel de riqueza es suficientemente alto, en el umbral de adopción, el depósito acumulado (o el crédito) es utilizado para invertir en tecnologías más avanzadas. Esto tiene implicaciones en el diseño de políticas de inclusión financiera para diferentes poblaciones meta. La inclusión financiera es necesaria, pero no suficiente, para el alivio de la pobreza.
Effects of the Great Recession on state output in Mexico
Authors: Mejía-Reyes Pablo , Díaz-Carreño Miguel Ángel
Published: January 2019

This paper investigates the effects of a battery of variables on total and sector output drops in the Mexican states during the Great Recession by estimating spatial and cross-section regression models. Our main results can be summarized as follows. First, there is evidence of spatial autocorrelation only in the case of total production and it seems to be negative, which does not support the hypothesis of interstate transmission of the recession. Second, total and sector production falls can be explained by the specialization in the production of tradable (mainly durable) goods. Third, exposure to external shocks plays an important role in the cases of industrial and services production, but not in total output. Fourth, there seems to be that federal fiscal policy has actually been pro-cyclical while state fiscal policies have contributed to mitigate the recession.
Efectos de la política monetaria en las decisiones de crédito al consumo

Published: January 2019

En esta investigación se propone un modelo cuyo propósito es mostrar los efectos de política monetaria en las decisiones de crédito bancario para consumo. Las hipótesis esenciales son: 1) la autoridad monetaria incide en la composición del balance bancario mediante el control de la tasa de interés; 2) la oferta de crédito es independiente de los depósitos. Entre los resultados principales se encuentran: 1) la utilización de la tasa de interés como instrumento de política monetaria influye indirectamente sobre las posibilidades de gasto de los consumidores, porque los bancos comerciales son forzados a modificar la composición de sus activos y pasivos en respuesta a las decisiones del banco central; 2) la demanda de activos y pasivos de los agentes depende esencialmente de la rentabilidad, riesgo y correlación entre los títulos. Por último, el modelo propuesto se calibra para medir los efectos de la política monetaria sobre las decisiones de los agentes.

El artículo hace un análisis de un monopolio que extrae un recurso no renovable que se enfrenta a dos mercados: uno nacional y uno exterior. Utilizamos evidencia de la economía mexicana respecto a las tres mezclas de petróleo que se producen y exportan. Utilizamos el modelo de Fischer y Laxminayaran (2004) y lo extendemos al caso de la economía mexicana con dos mercados y tres bienes. Los resultados que encontramos son los siguientes: (i) la mezcla más competitiva de la economía mexicana es la Maya al ser la más barata, la que más se produce y la que más se exporta; (ii) los precios son más volátiles que las variables de producción que se consideraron en el estudio; (iii) las elasticidades de las mezclas Istmo y Olmeca son las más inelásticas, por lo que un aumento en el precio de estas mezclas disminuye su cantidad exportada. La mezcla Maya tiene una elasticidad mayor, por lo que un aumento en su precio incrementa la cantidad exportada; (iv) las mezclas son complementarias y sustitutas entre ellas en casos específicos y (v) el corolario número 1 y la proposición número 1 del modelo de Fischer y Laxminarayan se replica en el caso de la economía mexicana.
¿Con qué probabilidad me toca ser víctima de un delito?
Authors: Cárdenas Rodríguez Oscar Javier
Published: January 2019

En este artículo se utilizan las teorías de exposición a estilos de vida y de actividades rutinarias para determinar qué factores inciden en la probabilidad de que una persona que vive en el área metropolitana de León, Guanajuato, sea víctima de un delito. Asimismo se determina la probabilidad con la cual personas con diferentes características pueden ser víctimas de una fechoría. Para tal fin se utiliza una base de datos recolectada por el Departamento de Economía y Finanzas de la Universidad de Guanajuato y financiada por el Programa de Mejoramiento del Profesorado y el Consejo Nacional de Ciencia y Tecnología. Los resultados indican que el tiempo de residir en la vivienda, el evitar ciertas rutas y la duración de la jornada laboral están correlacionadas con la probabilidad de ser víctima de un delito, mientras que variables como sexo y edad no muestran correlación alguna.

Published: January 2019

Utilizando datos por vivienda de la Encuesta sobre Victimización y Violencia aplicada en las áreas metropolitanas de Monterrey, Guadalajara y León en 2009, y datos agregados por AGEB del Conteo de Población y Vivienda 2005, este trabajo investiga el efecto de la localización sobre la probabilidad de que una vivienda sea víctima de robo, después de controlar por las características propias de la vivienda y de sus habitantes. Los principales resultados sugieren que las condiciones del vecindario y en menor medida las condiciones de los vecindarios cercanos son determinantes significativos de la probabilidad de que una vivienda sea robada.
FPGA-Based Space Vector Modulation of an Indirect Matrix Converter
Authors: Grabovski Edhuardo F. C. , Jappe Tiago K. , Mussa Samir A.
Published: January 2019

The insertion of powers sources onto the grid require an energy processing stage between generator and electrical grid, which adapts amplitude and frequency levels for alternating current (AC) quantities. The Indirect Matrix Converter is a candidate for such operation, although one of the greatest challenges of the topology lies in a way to command the switches while controlling the structure power-flow, as well as the synchronism between source–converter and converter–grid. Hence this paper presents a different view on the converter modelling and proposes a FPGA-based method to perform the Space Vector Modulation (SVM) and synchronism algorithms minimizing the resource consumption, focusing on digital processing algorithms and resource sharing to reduce resource consumption and the number of multipliers employed, ideal for implementation in low-cost FPGAs. Experimental results are shown using a prototype, demonstrating the efficacy of the implementation and verifying the converter behaviour.

Authors: Ionov M. V. , Zvartau N. E. , Konradi A. O.
Published: January 2019

The 2018 Joint Guidelines of the European Society of Cardiology and the European Society of Hypertension Specialists present a successful attempt to revise the approach to one of the most prevalent health problems worldwide. For more than two years, a Task Force of experts from the two Societies have assessed and have investigated the most recent scientific advances in the field of hypertension (HTN) in order to provide doctors with the adequate diagnostic tools, evaluation of cardiovascular risk and the optimal drug treatment. Undoubtedly, among a number of crucial changes of target blood pressure (BP) range along with the new sections dedicated to HTN in different circumstances, one can notice equally valuable, albeit subtle remarks about out-of-office BP and closely related telehealth. Extensive use of ambulatory and self-BP monitoring forced to match it to office BP. Booming information and communication technologies applied successfully in various therapeutic areas and have taken place in the Guidelines. From now digital health becomes a piece of the follow-up and adherence control. This brief report highlights the current position of European experts on telemedicine and outpatient methods of monitoring blood pressure.

Background.Vagus nerve stimulation has been proposed for the treatment of a number of diseases. The positive effects of vagus nerve stimulation on ischemic and reperfusion myocardial injury has been tested in experimental models. However, the escape effect of vagus activation on heart rate and the methodology to overcome this effect have not been reported properly.

Objective. The purpose of the study is to evaluate parameters of prolonged stimulation that decrease heart rate and allow overcoming the escape effect of vagus nerve activation.

Design and methods. We used Wistar rats (n = 9). Cervical section was performed under general anesthesia. Left vagus nerve isolated from adjacent tissue was contacted with custom stimulation electrodes and a custom pulse generator. Blood pressure was measured in the right common carotid artery. Limb electrocardiogram was continuously recorded. First, stimulation parameters repeatedly evoking vagal reaction (decrease in heart rate) without nerve damage were evaluated. Second, parameters of intermittent stimulation that allowed repeat and consistent heart rate decrease were assessed.

Results. During experiments, in 5 animals the following parameters leading to sustained 30 ± 20 % heart rate reduction were found: rectangular pulse, 30 Hz, 0,5 ms, 1–2 V (0,6– 0,8 mA). Stimulation with 50 Hz frequency led to nerve damage in 1 case. Stimulation with 20 Hz frequency led to heart rate over-suppression of heart rate and blood pressure. Intermittent nerve stimulation was tested in 4 animals and led to repeated heart rate decrease by 38 ± 15 %. The parameters which helped to avoid escape effect on heart rate change were the following: the length of stimulation episode of 45 s and interruption of stimulation for 15 s.

Conclusion. Intermittent electrical stimulation evokes vagal reactions on heart rate and allows overcoming the escape effect of vagal activation.

Background.One of the key problems of keeping records in medical information systems is the correctness of the data entry. Even the simplest decision support systems (DSS) can be highly useful regarding the reduction in the number of errors in entering data and recommendations.

Thepurposeof this study was to assess the effectiveness of the implementation of the simplest DSS, designed to minimize the number of input errors of the patient’s key characteristics and to implement a basic control for the recommendation section.

Design and methods.DSS was developed as a data analysis system of a medical information system that can perform functions directly integrating into a working medical information system. The study involved 7 cardiologists of the counseling and diagnostic center of the Almazov National Medical Research Centre (St Petersburg, Russia), who tested the established DSS for 10 weeks as part of their daily work on counseling patients with arterial hypertension. Altogether 1280 records were analyzed in the main group and 1060 in the control group. 

Results.In the group with notifications enabled, the total number of errors in the same section comprised 49,1 %, while 84,7 % of them were recorded during the first week of using the system, and by the time of the visit only 8,7 % of the errors were registered. In the control group, the total number of errors was 63,7 %, while 42,2 % remained uncorrected. In the recommendation section, the number of errors was almost identical in both groups, 24 % in the group that worked in the “fixation” mode, and 25,5 % in the group with error notifications enabled. At the same time, in the latter one, at the end of the visit, 7 % errors remained uncorrected. In a detailed analysis of the data in the “physical examination” section, the largest number of missing data related to the anthropometric indicators, especially the waist circumference. When assessing the quality of input data, we found that the group with enabled notifications showed a progressive decrease in the number of errors and unfilled fields in the “physical examination” section.

Conclusion.The use of the simplest DSS in the outpatient admission of patients with arterial hypertension can significantly improve the quality of the input of structured data necessary for patient risk stratification. It also contributes to the patient’s safety in terms of the correctness of the medical prescriptions.
A KONTRASZTÍV FRAZEOLÓGIAI KUTATÁSOK ALKALMAZOTT NYELVÉSZETI HOZADÉKA
Authors: ANDRIĆ Edit
Published: January 2019

A kontrasztív nyelvészeti vizsgálódások indíttatása általában a gyakorlatból ered, de a problémafelvető elemzések sokszor megmaradnak az elméleti fejtegetések szintjén, s gyakorlati eredményeiket nem tudjuk kellőképpen hasznosítani. A gyakorlat ugyanis idegenkedik az összevető elméleti elemzések bonyolultnak tűnő magyarázataitól, holott azok igen tanulságosak még az egynyelvű leíró nyelvészek számára is (mivel egy másik nyelv szempontjait vetítik az anyanyelv jellemzőire), de még inkább a nyelvi érintkezésekkel foglalkozó kutatóknak, illetve a bilingvális vagy többnyelvű közösségben élő személyeknek mindennapi nyelvhasználatukban bizonyul hasznosnak. A tanulmányban a magyar és szerb nyelvi kontrasztív vizsgálódások gyakorlati hasznáról esik szó, különös tekintettel a frazeológiai elemzések elméleti és nyelvhasználati tanulságaira.
