Summary
This work investigates the antiradical capacity and potential of Garcinia kola extracts to improve the biochemical markers associated with erectile function and its possible application in clinical treatment. Inhibitory properties of aqueous extract of G. kola on phosphodiesterase-5 (PDE-5), arginase, angiotensin I –converting enzyme (ACE), and acetylcholinesterase (AChE) in rat’s genitals tissues were evaluated. Likewise, G. kola extract was explored for reducing power (FRAP) and 1.1-diphenyl-2-picryl-hydrazil (DPPH) radical scavenging abilities. G. kola extract exhibited greater PDE-5 (IC50 = 47.52 ± 0.01 μg/mL), ACE (IC50 = 46.90 ± 0.87 μg/mL), AChE (IC50 = 44.85 ± 1.33 μg/mL) and arginase (IC50 = 47.71 ± 0.25 μg/mL) inhibitory activity in the corpus cavernosum tissue than PDE-5 (IC50 = 75.58 ± 2.04 μg/mL), ACE (IC50 = 53.00 ± 0.30 μg/mL), AChE (IC50 = 54.57 ± 1.50 μg/mL) and arginase (IC50 = 69.68 ± 2.42 μg/mL) inhibitory activity in the testicular tissue homogenate. Furthermore, G. kola exhibited radical scavenging abilities against FRAP and DPPH* radicals. Hence, our results revealed that G. kola extracts are good sources for the development of nutraceuticals and pharmacological properties with attributes to enhance erectile performance.

Published: April 2019

Abstract
Organisations should evaluate their goals in the areas of customer service provision, overall organisational strategy, finance, and human resource management. The performance of specific services provided to the client should be monitored and evaluated in greater detail. The comparison should be made between similar organisations aiming to improve services and technical efficiency. Most organisations, profit and non-profit alike, do not know how to evaluate and compare their efficiency. Retirement homes were selected for evaluation. The review focused on the technical efficiency for the years 2015-2017. To achieve the goal, Data Envelopment Analysis (DEA) was used as a specialised model tool for assessing the technical efficiency, performance or productivity of a group of homogeneous or comparable production units based on selected inputs and outputs. Due to different types of inputs and outputs, the method was selected from among multi-criteria decision-making methods. Two models, Model X and Model Y, including specific inputs and outputs, were designed to evaluate and compare the technical efficiency of selected retirement homes. According to the results, the output-oriented model (Model Y) was more effective for retirement homes compared to the input-oriented model (Model X). The value added could be seen in the model combination and comparison between different studies, which helps to understand the transferability of the results. The analysis confirmed the necessity to combine the DEA method with the quality of service assessment to be able to benchmark the real efficiency of service of a selected type of an organisation.

Abstract
Therefore the carried out study aimed at determination of the effect of high-calcium brown coal ash and compost being produced from municipal sewage sludge on the content and bioaccumulation of heavy metals in potato tubers, wheat grains and rapeseeds during a three-year period. Rapeseeds contained most Cd whereas wheat rains less. Potato tubers, wheat grains and rapeseeds contained more Mn, Ni and Zn in the fertilization objects with municipal sewage sludge with or without coal ash and compared to those where calcium carbonate or coal ash had been introduced into the soil at a dose corresponding to 1.5 Mg CaO · ha–1 at the beginning of this study. Differences in the Mn, Ni and Zn contents in test plants between the fertilization objects with sewage sludge of with and without addition of ash were not significant.

Abstract
The purpose of this paper was to compare the costs of three noninvasive diagnostic investigations as the initial tests in peripheral artery disease management in Romania.
A cost analysis of three imaging diagnostic tests was performed at the university hospital in Timișoara, Romania. The tests were as follows: arterial Duplex Ultrasound Scanning, Computed Tomography Angiography, and Contrast-enhanced Magnetic Resonance Angiography. The evaluation of the diagnostic test performance was performed together with the calculation of the real costs of each investigation. Finally, an economic evaluation of different diagnostic tests was done.
A number of 46 patients (36 male and 10 female) were included in the study. The selected patients have been subjected to a total number of 61 diagnostic tests prior to the therapeutic decision. Both in terms of sensitivity and specificity, Duplex Ultrasound Scanning and Computed Tomography Angiography showed little difference in our study. The cost analysis results showed a net economic advantage if Duplex Ultrasound Scanning is applied as a diagnostic method under conditions of obtaining a similar effect.
In conclusion, Duplex Ultrasound Scanning is accurate, safe, and cost-effective in designing the final therapeutic plan in peripheral artery disease (PAD), especially in the femoropopliteal segment.

Published: April 2019

Observando a emergência de uma controvérsia acerca da obra do teórico brasileiro Paulo Reglus Neves Freire (1921-1997), vista por inúmeros educadores em todo o mundo como uma referência respeitável teórica e metodologicamente, mas também apontada por alguns setores da sociedade como tendenciosa e um perigo doutrinário à juventude, apresentam-se os resultados de um mapeamento sistemático realizado a partir de possíveis artigos científicos que versam sobre a presença da teoria marxista no trabalho de Paulo Freire. O objetivo consistiu em identificar quais são as influências de Karl Marx (1818-1883) nas concepções de Paulo Freire. Para a realização desse mapeamento, sete mecanismos de busca acadêmicos foram consultados, retornando um total de 71 artigos, dos quais, após a aplicação dos critérios de inclusão e exclusão, extraíram-se três artigos acadêmicos que compuseram esse estudo. Esta pesquisa mostrou que a relação entre Freire e Marx se dá por meio de uma prática reflexiva, a práxis, que busca, de forma simultânea, abordar a teoria e a prática em prol de uma transformação social. Além disso, a dialogicidade – essencial à pedagogia da libertação freiriana – possui forte influência do humanismo marxista.
“Me gustaría enseñar en un lugar que no sea la escuela”: sentidos en torno a las prácticas de enseñanza en contextos formativos diversos y alternativos a la escuela secundaria “tradicional”
Authors: Gallardo Soledad , Fabrizio María Laura 
Published: April 2019

En este artículo reflexionaremos sobre los sentidos desplegados por estudiantes de antropología que están realizando su formación docente en la Universidad de Buenos Aires (UBA), en torno a prácticas de enseñanza y los espacios formativos que eligen para llevarlas a cabo. A partir de una perspectiva socio-antropológica abordaremos, por un lado, los sentidos que aparecen en las que toman estos futuros antropólogos-docentes respecto a la elección de la justicia educativa para realizar sus "prácticas"; y por otro lado, nos detendremos en el proceso de deconstrucción / desnaturalización que pongan en marcha para definir y realizar propuestas pedagógicas y antropológicas que resulten significativas, en contextos históricamente situados, para los destinatarios de la enseñanza.

The matrix theory of mathematical field and the motion of mathematical points in n-dimensional metric space
Authors: Dymnikov Alexander D. 
Published: April 2019

A matrix theory of n-dimensional mathematical field and the motion of mathematical points in n-dimensional metric space is developed. Two spaces are considered: the n-dimensional space of an integrable coordinate vector [Formula: see text] with the integrable metric [Formula: see text] and the n-dimensional space of a non-integrable but differentiable coordinate vector [Formula: see text], where [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text]. We call the coordinate space of the vector Q as the absolute space. The derivatives of the non-integrable but differentiable matrix e are expressed through the elements of the Christoffel symbols and the elements of the Ricci and Riemann curvature matrices. The absolute velocity vector [Formula: see text] and the absolute mathematical field matrix [Formula: see text] are introduced. We obtain two groups of the matrix field equations, the first of which is written in the two following forms: [Formula: see text], [Formula: see text], where [Formula: see text] the trace of the matrix P, K is is the absolute Ricci matrix function, [Formula: see text] is the n-dimensional absolute velocity vector, ρ is a scalar function, which is the eigenvalue of K with the corresponding eigenvector [Formula: see text]. The interpretation of this pure mathematical theory in 4-dimensional space is the theory of the electromagnetic and gravitational fields and the motion of charged and neutral particles in the electromagnetic-gravitational field.
Advanced method for cryptographic protocol verification
Authors: El Kadhi Nabil , El-Gendy Hazem 
Published: April 2019

Based on a previous work using abstract interpretation for secret property verification, we propose a new method for protocol verification combining abstract interpretation for Input/Output set description and finite state machine for property propagation and verification. Generating Input/Output set for FSM is a bit difficult specially when one want to apply such technique on cryptographic protocol implementation. It is true that one can verify protocol specification, but in such case one cannot discover any significant logical follows introduced by implementation. To overcome this, we develop a particular semantic defined for cryptographic protocol verification, that facilitates verifying or detecting a large set of faults and attacks. Faults and attacks will be described as scenarios with a set of preconditions and post conditions. The FSM based method is used to discover a transition is possible from an initial set (inputs) to a final state describing a fault or a global attack state. This semantic along with the model and the verification tool SSPV allow the prove of more key security properties.
Análisis del nivel de profesionalización y su influencia en la cultura organizacional de las microempresas del cantón Tulcán

Published: April 2019

El clima organizacional ha sido uno de los factores más importantes para el desarrollo de una empresa o una institución en todos sus ámbitos: productivo, administrativo, estructural y evolutivo. Las organizaciones con un clima organizacional deficiente pueden con mucha dificultad aspirar a ser mejores, puesto que su recurso más valioso se encuentra desintegrado, incomunicado, insatisfecho, preocupado y desmotivado. En Ecuador las microempresas son una alternativa para la creación y mantenimiento del empleo; su sostenibilidad está sujeta a la situación familia – empresa. La presente investigación estuvo enfocada en determinar la incidencia de la profesionalización en la cultura organizativa del sector micro empresarial del Cantón Tulcán, especialmente en realizar una aportación de carácter teórico, que implica evidencia empírica: ayudar al esclarecimiento de un constructo complejo y dinámico como lo es el clima y desarrollo organizacional. Las personas objeto de la investigación indican que la mayoría de las organizaciones en nuestro país, por no decir todas, son tradicionales sustentadas en la división horizontal del trabajo y vertical en la toma de decisiones, con estilos de liderazgo autocráticos en donde los subordinados están condenados solo a cumplir órdenes, incapacitados de pensar por sí mismos; esto hace que los miembros de la organización se dediquen exclusivamente a sus labores asignadas sin importarles lo que hagan los demás y escasamente comprometidos con la visión, misión, objetivos y metas. Así mismo, las organizaciones objeto de estudio presentan falencias en lo referente a la profesionalización del talento humano, lo que impide desarrollar una cultura organizacional con enfoque a una filosofía propia orientada a generar estrategias técnicas. que deben ser tomadas en cuenta con el propósito de evaluar y reconocer valores que son necesarios dentro de la organización y por lo tanto no pierda viabilidad ni vigencia en sus procesos de comunicación, factor que es elemento clave para el cambio de cultura, capaz de enfrentar un proceso de globalización y competitividad.
