Published: March 2021

The main purpose of health systems is to ensure citizens utilize the health services by adequately and effectively. As the quantity and the quality of health services are improved, health indicators such as quality of life and life expectancy at birth are also improved. Health indicators and health care expenditures allow policy makers to compare health systems and to monitor and evaluate the current situation of the health systems. The main reason behind the international comparison of health indicators and expenditures is to enable countries to benchmark successful health systems. In this context, the aim of this study was to compare health indicators and health expenditures of 28 European Union (EU) countries, 6 EU candidate countries and 3 European Free Trade Association (EFTA) countries by cluster analysis method. As a result of the clustering analysis, the countries were grouped under 3 clusters. The public, private and out-of-pocket health expenditure per capita averages of the first cluster, which Turkey was included in, was the lowest among three clusters. It was determined that the cluster in which Turkey was placed falled behind other two clusters in terms of life expectancy at birth, number of physicians and nurses, maternal mortality rate, and smoking ratio health indicator averages.

Revealing Challenges within the Application of Machine Learning Services – A Delphi Study
Authors: Philipp Robert , Mladenow Andreas , Strauss Christine , Voelz Alexander
Published: March 2021

Over the past years, Machine Learning has been applied to an increasing number of problems across numerous industries. However, the steady rise in the application of Machine Learning has not come without challenges since companies often lack the expertise or infrastructure to build their own Machine Learning systems. These challenges led to the emergence of a new paradigm, called Machine Learning as a Service. Scientific literature has mainly analyzed this topic in the context of platform solutions that provide ready-to-use environments for companies. We recently have developed a platform-independent approach and labeled it Machine Learning Services. The aim of the present study is to identify and evaluate challenges and opportunities in the application of Machine Learning Services. To do so, we conducted a Delphi Study with a panel of machine learning experts. The study consisted of three rounds and was structured according to the five steps of the Data Science Lifecycle. A variety of challenges from the areas “Communication”, “Environment”, “Approach”, “Data”, “Retraining, Testing, Monitoring and Updating”, “Model Training and Evaluation” were identified. Subsequently, the challenges revealed by the Delphi Study were compared with previous work on Machine Learning as a Service, which resulted from a structured literature review. The identified areas serve as possible future research fields and give further implications for practice. Alleviating communication issues and assessing the business IT infrastructure prior to the machine learning project are among the key findings of our study.
An Ensemble Framework of Multi-ratio Undersampling-based Imbalanced Classification
Authors: Komamizu Takahiro , Ogawa Yasuhiro , Toyama Katsuhiko
Published: March 2021

Class imbalance is commonly observed in real-world data, and it is problematic in that it degrades classification performance due to biased supervision. Undersampling is an effective resampling approach to the class imbalance. The conventional undersampling-based approaches involve a single fixed sampling ratio. However, different sampling ratios have different preferences toward classes. In this paper, an undersampling-based ensemble framework, MUEnsemble, is proposed. This framework involves weak classifiers of different sampling ratios, and it allows for a flexible design for weighting weak classifiers in different sampling ratios. To demonstrate the principle of the design, in this paper, a uniform weighting function and a Gaussian weighting function are presented. An extensive experimental evaluation shows that MUEnsemble outperforms undersampling-based and oversampling-based state-of-the-art methods in terms of recall, gmean, F-measure, and ROC-AUC metrics. Also, the evaluation showcases that the Gaussian weighting function is superior to the uniform weighting function. This indicates that the Gaussian weighting function can capture the different preferences of sampling ratios toward classes. An investigation into the effects of the parameters of the Gaussian weighting function shows that the parameters of this function can be chosen in terms of recall, which is preferred in many real-world applications.

Lipid Bilayer Structure Refinement with SAXS/SANS Based Restrained Ensemble Molecular Dynamics
Authors: Cherniavskyi Yevhen , Baoukina Svetlana , Holland Bryan W. , Tieleman D. Peter
Published: March 2021

Small-angle scattering is a powerful technique that can probe the structure of lipid bilayers on the nanometer scale. Retrieving the real space structure of lipid bilayers from the scattering intensity can be a challenging task, as their fluid nature results in a liquid-like scattering pattern which is hard to interpret. The standard approach to this problem is to describe the bilayer structure as a sum of density distributions of separate components of the lipid molecule and then to fit the parameters of the distributions against experimental data. The accuracy of the density-based analysis is partially limited by the choice of the functions used to describe component distributions, especially in the case of multi-component bilayers. The number of parameters in the model is balanced by the need for an accurate description of the underlying bilayer structure and the risk of overfitting the data. Here, we present an alternative method for the interpretation of small-angle scattering intensity data for lipid bilayers. The method is based on restrained ensemble molecular dynamics simulations that allow direct incorporation of the scattering data into the simulations in the form of a restraining potential. This approach combines the information implicitly contained in the simulation force field with structural data from the scattering intensity and is free from prior assumptions regarding the bilayer structure.

Covalent organic frameworks (COFs) are crystalline organic materials of interest for a wide range of applications due to their porosity, tunable architecture, and precise chemistry. However, COFs are typically produced in powder form and are difficult to process. Herein, we report a simple and versatile approach to fabricate macroscopic, crystalline COF gels and foams. Our method involved the use of dimethyl sulfoxide as a solvent and acetic acid as a catalyst to first produce a COF gel. The COF gel was then washed, dried, and reactivated to produce a macroscopic, crystalline, porous COF foam. We demonstrated this synthesis for six different imine COFs and found that the crystallinities and porosities of the COF foams matched those of COF powders. Electron microscopy revealed a robust hierarchical pore structure, and we showed that the COF foams can be used as absorbents in oil-water separations, for the removal of organic and inorganic micropollutants, and for the capture and retention of iodine. This study provides a versatile and simple approach for the fabrication of COF foams and will provide novel routes for incorporating COFs in applications that require macroscopic, porous materials.

Future rechargeable Li metal batteries (LMBs) require a rational electrolyte design to stabilizethe interfaces between the electrolyte and both the lithium metal anode and the high voltagecathode. This remains the greatest challenge in achieving high cycling performance inLMBs. We report an ether-aided ionic liquid electrolyte which offers superior Li metaldeposition, high voltage (5 V) stability and non-flammability. High performance cycling ofLiNi0.8Mn0.1Co0.1O2 (4.4 V) and LiNi0.6Mn0.2Co0.2O2 (4.3 V) cells is demonstrated with highcoulombic efficiency (>99.5%) at room temperature and elevated temperatures, even at highpractical areal capacity for the latter of 3.8 mAh/cm2 and with a capacity retention of 91% after100 cycles. The ether-ionic liquid chemistry enables desirable plated Li microstructures withhigh packing density, minimal ‘dead’ or inactive lithium formation and dendrite-free long-termcycling. Along with XPS studies of cycled electrode surfaces, we use molecular dynamicssimulations to demonstrate that changes to the electrolyte interfacial chemistry upon additionof DME plays a decisive role in the formation of a compact stable SEI.

Published: March 2021

Objective. To characterize the design of excise taxes on sugar-sweetened beverages (SSBs) in Latin America and the Caribbean and assess opportunities to increase their impact on SSB consumption and health.

Methods. A comprehensive search and review of the legislation in effect as of March 2019, collected through existing Pan American Health Organization and World Health Organization monitoring tools, secondary sources, and surveying ministries of finance. The analysis focused on the type of products taxed, and the structure and base of these excise taxes.

Results. Out of the 33 countries analyzed, 21 apply excise taxes on SSBs. Seven countries also apply excise taxes on bottled water and at least four include sugar-sweetened milk drinks. Ten of these excise taxes are ad valorem with some tax bases set early in the value chain, seven are amount-specific, and four have either a combined or mixed structure. Three countries apply excise taxes based on sugar concentration.

Conclusions. While the number of countries applying excise taxes on SSBs is promising, there is great heterogeneity in design in terms of structure, tax base, and products taxed. Existing excise taxes could be further leveraged to improve their impact on SSB consumption and health by including all categories of SSBs, excluding bottled water, and relying more on amount-specific taxes regularly adjusted for inflation and possibly based on sugar concentration. All countries would benefit from additional guidance. Future research should aim to address this gap.

Published: March 2021

Objective.To identify factors associated with chronic kidney disease of non-traditional causes among children in Guatemala.

Methods.A cross-sectional survey was conducted. The study population was all pediatric patients with stage 5 chronic kidney disease active in FUNDANIER’s pediatric nephrology unit (N = 156). Simple random sampling led to a total of 100 participants. Data collection consisted of a questionnaire addressing individual and household characteristics, access and utilization of health care, and place of residence when the disease began. Chronic kidney disease etiology was obtained from medical records. Municipality-level secondary data were collected. Descriptive statistics were estimated. Logistic regression was used for bivariate and multivariate analysis.

Results.The odds ratio (OR) for almost all variables approached 1. Notable exceptions in household characteristics were mother’s education level up to primary school (OR 2.2727) and living in an urban setting when symptoms began (OR 0.4035). Exceptions in municipal characteristics are zones with intensive small-scale agriculture (OR 3.8923) and those with intensive large-scale agriculture (OR 0.3338). P-values and confidence intervals show that the sample was not big enough to capture statistically significant associations between variables.

Conclusions.Study findings suggest that factors associated with chronic kidney disease of non-traditional causes among children in Guatemala are intensive agricultural practices in their municipality of residence, and mother’s level of education. Future research in children could use case-control designs or population-based studies in agricultural communities. Public health interventions that involve kidney function screening among children are recommended.

Moreover, prior research called for disintegrating the strategic orientation and assessing their effects on organizational performance. Thus, this study is the first of its nature – disintegrating the market orientation (MO) construct and using data from 213 SMEs of Pakistan, collected through survey method, which reports on how the deployment of entrepreneurial orientation (EO) as moderator produces synergistic effect and strengthens the MO dimensions –organizational performance links. The results indicate that the MO dimensions are positively and significantly related to organizational performance. Moreover, EO significantly and positively moderates the MO dimensions and organizational performance relationships. The study provides avenues for future research.
SMEs’ competitiveness and international trade in the era of Global Value Chains (GVCs) in Tanzania: An assessment and future challenges
Authors: Lwesya Francis
Published: March 2021

International trade continues to play a crucial role in economic transformation in African countries. The rise of Global Value Chains (GVCs) presents opportunities through which international trade can be effectively conducted. GVCs facilitate organization of trade, international production and investment by locating different stages of production process across varied countries. This presents opportunities to integrate Small and Medium Enterprises (SMEs) into global trading systems but also may generate challenges particularly to resource constrained SMEs. Reviewing the challenges for the participation in international trade and possible integration into GVCs by Tanzania’s SMEs, the results show that the major challenges for SMEs internationalization are international marketing related constraints and global competition (69%), supply side constraints (56%), unfriendly investment climate (50%) and financial constraints (37.5%). As such, the role of trade policies remains critical in mitigating some of these challenges through formulating friendly legal and regulatory frameworks, enhancing SMEs productivity by building their managerial and technical capacities, minimizing trade costs, and increasing trade openness. However, given the current global, regional and domestic developments in Tanzania, trade policies need review so as to respond to the changing global trade landscape but also promote policy harmony, coherence and complementarities among varying implementing institutions, deficiency of which is debilitating policy implementation at present
Determination of the effective stiffness of a unidirectional layer by the finite element method and approximate formulas
Authors: Olegin I. P. , Burnysheva T. V. , Laperdina N. A.
Published: March 2021

Layered composites formed by unidirectional layers are widely used in aviation in the most loaded areas of the aircraft. Data on the elastic properties of the layers are required for the strength and stiffness calculation of structural elements made of such materials. There are two possible approaches to address the problem. The first approach is based on solving the problem of micromechanics using methods of the theory of elasticity. The second approach consists in developing a simplified model of a unidirectional layer. Analysis of the model can provide for fairly simple formulas for determination of the effective stiffness of a unidirectional layer. A comparative analysis of the results obtained in both approaches revealed the limits of applicability of approximate formulas derived for evaluating the effective characteristics of the different types of composites depending on the volume content of fibers. The effective elastic characteristics of unidirectional composites are determined by the finite element method in the framework of the linear theory of elasticity. The boundary value problem is solved for a characteristic representative element selected in accordance with the physical and geometric parameters of the medium of an ordered structure. A set of algorithm-programs has been developed under ANSYS environment which automates calculations of the elastic characteristics of materials depending on the volume content of fibers at different ratios of the elastic properties of fibers and binder, and on the parameters of the curvature of the fiber cross-sectional profile. The results obtained by the numerical method are compared with the data obtained experimentally and by approximate formulas.
The use of photogenerated iodine for the determination of isoniazid in solid dosage formulation
Authors: Turusova E. V. , Nasakin O. E. , Lyshchikov A. N.
Published: March 2021

A shot cut method for the determination of isoniazid in a solid dosage formulation (DF) has been developed. The method is based on isoniazid titration with a solution of photogenerated iodine obtained as a result of irradiation of an auxiliary solution containing potassium iodide, a mixture of sensitizers (sodium eosinate, fluorescein, auramine taken in a molar ratio of 1:1:1) and phosphate buffer solution (pH 7.5). Since the titrant content in the cell was controlled using the voltammetric method (amperometric titration with two polarized electrodes), the interaction of a physiologically active compound with the latter was accompanied by a decrease in the amount of titrant in the cell and, hence, in the current in amperometric circuit. Stabilization of the current in the circuit of the amperometric setup indicated the completeness of the reaction, and, therefore, provided estimation of the content of a physiologically active compound in the dosage formulation. Further irradiation of the solution and measurement of the generation time required to replenish the loss of titrant in the cell also made it possible to regulate the content of isoniazid in the preparation. The technique was tested on the samples of solid dosed formulations. It was shown that the components of the tablet mass (calcium stearate monohydrate, polysorbate, crospovidone and potato starch) do not affect the results of the determination of physiologically active compound provided that the analyzed form is obtained at room temperature. The determined content of isoniazid in a solid dosage formulation varies in the range of 286.0 – 296.0 mg and falls within the range recommended by the General Pharmacopoeia Monograph 1.4.2.0009.15 (285 – 315 mg), which indicates that the quality of the drug meets the GMP standards. The linear dependence of the analytical signal on the concentration of physiologically active compound is observed in the range of 161 – 1610 mg for the drug «Isoniazid. Tablets, 300 mg». The calculated detection limits and quantitative determination are 13.5 and 41.0 mg (both in terms of change in the current strength and in the time of titrant generation), respectively. The developed photochemical method for the determination of isoniazid in solid dosed formulation is easy to use, meets the requirements set out in the guidelines for validation of bioanalytical methods, and does not require expensive equipment. The method can be recommended for routine control of the DF quality indicators in any analytical laboratory.

Como freio a eventuais excessos de métodos didáticos ou modelos explicativos generalizantes, proponho a perspectiva concreta do professor na busca de soluções efetivas para interferir no processo de aprendizagem. Mostro então como essa atitude se expressa no fomento da escrita em cursos básicos de alemão com o material didático Blaue Blume, utilizando para isso o Laboratório de Avaliação do Moodle. Também são discutidos alguns detalhes técnicos e opções de uso e ajustes dessa ferramenta.

One of the conditions for the spread of the Russian language is the education of foreign students in Russian universities. Consequently, the search for new approaches to teaching Russian as a foreign language becomes relevant. Practice has shown that literature is a guide to understanding the characteristics of the Russian language and the development of oral speech. The object of the study is a literary text in the system of teaching the Russian language. The purpose of this work is to search for the effective forms and methods of teaching foreign students the Russian language on the basis of literary text. The results of the study showed that the most effective form of training is the use of educational technologies based on practice-oriented aspects of semiotics. On the material of the Gogol's poem "Dead Souls" the technique of working with literary text is shown.

Las técnicas de infiltración de las aguas pluviales en medio urbano se encaminan a disminuir los caudales y/o los volúmenes de aguas pluviales. Limitan al mismo tiempo los fenómenos de colada de las superficies urbanas por las escorrentías, y permiten pues disminuir sus cargas contaminantes. Sin embargo, el traslado potencial de los contaminantes contenidos en esas aguas constituye una amenaza para la calidad de los suelos subyacentes y aguas subterráneas. El objetivo de las cuencas de infiltración consiste también en retener la carga contaminante contenida en esas aguas y de fijarla para que el efluente que deja la cuenca no tenga ningún impacto negativo en el medio natural. Por lo tanto, la durabilidad o la eficacia de esos sistemas de infiltración a largo plazo deben estudiarse. El objetivo de este estudio es proponer un método de caracterización de la heterogeneidad espacial, a partir de concentraciones en metales pesados medidas en la cuenca Django Reinhardt si, a escala anual, las concentraciones en contaminantes, o su repartición, han progresado. Tres campañas medidas han sido realizadas a intervalos de un año: la primera, en abril de 2005, cuenta con 103 puntos; la segunda, en febrero de 2006, agrupa 92 puntos y el último, en julio de 2007, reúne 99 puntos. Los parámetros analizados para cada muestra son: el plomo (Pb), el cobre (Cu), el cinc (Zn) y el contenido en agua (W). El método de caracterización utilizado fue el Krigeage. Los análisis muestran sobre los 5 cm de suelos estudiados que la cuenca está contaminada a la superficie. También permitieron detectar una acumulación de los contaminantes entre las tres campañas, sobre todo a la entrada de la cuenca y en la parte más antigua que el resto del sistema. Por fin, sobre los 5 cm de suelos estudiados un balance de masa total de metales pesados prendidos en la cuenca se reconstituyó.

Continuando con el esfuerzo de mejorar el pronóstico estadístico de precipitación estacional en la costa sudamericana, datos mensuales de precipitación de tres regiones costeras del Ecuador (provenientes del producto GPCC Full Data Reanalysis Version 3) fueron analizados para ver su comportamiento con respecto a nuevos índices predictores. El análisis, que permitiría una estimación más consistente de los niveles estacionales de precipitación, se realizó con el programa WFCC/WTC distribuido por NOAA-OGP/UCR. Los índices predictores fueron basados en combinaciones lineales de la TSM promedio de la región Niño 3 y del índice de oscilación Madden-Julian (OMJ). Los resultados sugieren que los índices propuestos no mejorarían el esquema de predicción estacional ya existente, ya que los resultados estadísticamente más fuertes permiten pronosticar adecuadamente tan sólo el final de la estación lluviosa, los cuales tienen una utilidad limitada. Se sugiere que el mejoramiento moderado que se observó en dichos pronósticos resulta de la interferencia entre la señal del Niño 3 y efectos rezagados de la subsidencia asociada con la OMJ. Además, el método de análisis probado, el cual fue automatizado durante el presente estudio, se ha mostrado efectivo, facilitando evaluaciones futuras del esquema propuesto.
Relevamiento y mitigación de los impactos del cambio climático y actividades humanas en la cantidad y calidad del agua Subterránea del acuífero Guarani en Ribeirão Preto, Brasil

El acuífero Guaraní es uno de las más grandes fuentes de agua subterránea de buena calidad en el mundo, ubicado en 4 países sudamericanos. En regiones como la ciudad de Ribeirão Preto (Brasil), el acuífero viene siendo utilizado intensamente en los últimos 30 años, lo que ha causado una caída de más de 60 m. Además, muchas áreas de recarga del acuífero vienen siendo utilizadas con agricultura intensiva, la cual podría llevar a su contaminación. Existen también riesgos de cambio climático, que podrían aumentar los riesgos de sostenibilidad del acuífero en el futuro. Los objetivos de este trabajo fueron cuantificar los riesgos actuales a la cantidad y calidad de agua y estimar los riesgos relativos al aumento de la población y cambio climático en los próximos 50 años. El área seleccionada para el estudio fue un polígono de 2.500 km2 alrededor de la ciudad de Ribeirão Preto, y las condiciones analizadas fueron aquellas relativas al mejor y peor escenario, y un escenario intermedio, para la población y clima. En términos de cantidad de agua, la disminución de la recarga por el cambio climático y por el aumento del bombeo (demanda) en la zona urbana podría llevar a una depleción del agua subterránea en el año 2050. La situación geológica particular del acuífero local, reduciendo el flujo de agua subterránea regional, contribuye a la tendencia de reducción. Entretanto, como el 65% del volumen del agua subterránea no había sido utilizado todavía en 2007, aún es posible manejarla visando su sustentabilidad futura. En términos de calidad del agua, un análisis de riesgo, basado en la vulnerabilidad y el potencial de contaminación de las áreas agrícolas, indicó que 90km2 del área de recarga presentan alto riesgo de contaminación. Medidas de mitigación y adaptación fueron entonces sugeridas para la gestión del acuífero. Las medidas identificadas como más viables fueron el uso suplementar de agua del río Pardo (cantidad) y el uso de pesticidas de menor impacto (calidad).

En este trabajo se cuantificó el impacto de la minería aurífera en la disponibilidad de agua para riego en el valle de Jáchal, provincia de San Juan, Argentina. A partir del consumo hídrico de dos concesiones mineras sobre la cuenca del río Jáchal, Veladero (en explotación) y Lama (en etapa de estudio de impacto ambiental), se calculó el uso consuntivo de agua y el efecto regulador del embalse Cuesta del Viento. Suponiendo que los dos yacimientos mineros extraigan el volumen de agua máximo necesario para su funcionamiento en forma constante durante todo el año, se verificará una disminución de 4.47% en el caudal del río Jáchal, equivalente al agua que habría que entregar para regar una superficie de 728 ha de cultivos según el patrón actual de uso de suelo agrícola. Teniendo en cuenta el área en producción agrícola, la capacidad de distribución de la red de riego y la oferta hídrica promedio del río Jáchal, esto no generará déficit hídrico en los cultivos. Si bien en un año con bajas precipitaciones en cabecera de cuenca se puede contar con la reserva del dique Cuesta del Viento, en casos en los que el ciclo hidrológico seco se extendiese por más de cuatro años se debería tener en cuenta medidas para asegurar la provisión de agua para los cultivos de Jáchal.

Jeruju (Acanthus ilicifolius) is abundant in mangrove ecosystems in Indonesia and has high antibacterial, antioxidant and anti-inflammatory properties. In addition, the many uses of hazardous chemicals in anti-acne creams are the reason for the need of alternative natural ingredients for making anti-acne creams. So that in this study the use of jeruju leaf extract was added as an active ingredient of anti-acne cream. This research method was carried out by extracting the leaves of jeruju using ethanol solvent then made anti acne cream with extract concentrations of 1%, 5%, 10%, 15%. After that, sensory testing, TPC, antioxidant activity and antibacterial activity against acne-causing bacteria, namely Propionibacterium acne were carried out. The results of the antibacterial activity test of the four concentrations against P.acne produced inhibition zones with a range of values, namely 10.35-12.72 mm.. In testing the antioxidant activity, the best results were obtained at a concentration of 15% extract with an IC50 value of 98.80 ppm. From these results it can be concluded that jeruju is proven to inhibit P.acne bacteria, so that it has the potential to be used as an active ingredient in making anti-acne creams. Suggestions that can be given for further research are to make jeruju extract into a form that is more acceptable to consumers in terms of odor and color without reducing its content.
