Authors: Vargas-Bernal Rafael
Published: November 2020

Electromagnetic environmental shielding is one of the main research topics for the development of aeronautical and space applications. Numerous research groups around the world study the problems that space systems and astronauts experience when these are subjected to space radiation. Despite the progress made so far, different proposals of advanced materials have been continuously proposed throughout the history of space career to protect space systems and astronauts against the solar particle events (SPE), cosmic rays galactic (GCRs), and proton-electron radiation (PERs). This chapter presents the recent advances made about space environmental shielding and that have been reported so far to visualize the future perspectives that this type of research must carry out so that future space voyage is completely reliable for space systems and astronauts. This research area is fully current, and its experimental success will depend on the work done by all space researchers and professionals.

Authors: Smirnov Maxim , Sidorov Nikolay V. , Teplyakova Natalya A. , Palatnikov Mikhail , Syuy Alexander Vjacheslavovich
Published: November 2020

The photoluminescence intensity in lithium niobate crystals close to the stoichiometric composition is lower than in a congruent crystal was established. An increase in the Li / Nb ratio leads to a shift in the photoluminescence bands to the short-wavelength region of the spectrum and a change in the fundamental absorption edge of the crystals under study. It was shown that, in addition to point defects in the cationic sublattice, complex defects due to the presence of OH groups in the structure can also contribute to photoluminescence.

Published: November 2020

In the present work, bismuth-based nanoparticles of various compositions were obtained by pulsed laser ablation of a metallic bismuth target in water and air using a Q-switch Nd:YAG laser (wavelength of 1064 nm, pulse duration of 7 ns, frequency of 20 Hz, and pulse energy of 160 mJ). Then the samples were annealed in air at temperatures up to 600°C. A comparative analysis of the obtained powders was carried out using methods of X-ray diffraction, transmission electron microscopy, specific surface area measurements, IR-Fourier and UV-Vis Spectroscopy. The photocatalytic activity of the synthesized materials in the process of Rhodamine B decomposition under irradiation of a LED source (375 nm) was also studied.

Radiation stability of ZnO hollow particles under 100 keV proton and electron exposure have been investigated. The experimental data were compared with the calculated ones obtained by modeling in the GEANT4 software package. Hollow particles have better radiation stability compared with bulk microparticles cause by low defects accumulation in the hollow particles, which was confirmed by simulation in GEANT4.
Identification of Structure Ordering of Melt-Spun Fe70Cr15B15 Alloy by the Entropy Functionals
Authors: Frolov Anatoly M. , Pisarenko Tatiana A.
Published: November 2020

New techniques for the analysis of complex images were advanced by the example of asurface microrelief of the Fe70Cr15B15 alloys, obtained by the melt-spinning at different linearvelocity of a quenching roller. Proposed techniques are based on the fast Fourier transform of theimage using digital signal processors. The degree of morphological ordering/disordering of ribbonswas determined due to the parameterization of mode spectra by entropy functionals. The best glassforming ability for alloys of the studied composition was obtained at 30 m/s.

Authors: Ivanov Lev Aleksandrovich , Kaminskaya Tatiana P. , Tereshina Irina Semenovna , Davydov Vladislav , Popov Vladimir V. , Politova Galina Aleksandrovna , Dobatkin Sergey V.
Published: November 2020

Magnetic force microscopy (MFM) and magnetometry, scanning electron microscopy (SEM) and atomic force microscopy (AFM) are used to study the magnetic and structural properties of the (Nd,Pr)-Fe–B and (Nd,Ho)-(Fe,Co)-B alloys. The alloys are synthesized using an arc or induction furnaces. The nanocrystalline state of the (Nd,Ho)-(Fe,Co)-B alloys is reached by two techniques, namely, melt spinning (MS) and severe plastic deformation (SPD). Hydrogenation and multistage treatment of (Nd,Ho)-(Fe,Co)-B alloys, which includes severe plastic deformation of melt-quenched ribbons and subsequent heat treatment, is also used. The surface morphology and domain structure of samples are studied. These pictures are used to interpret the observed magnetic hysteresis loops of the samples. It was found that multistage treatment allows one to obtain samples with higher values of coercivity due to the formation of a special microstructure with oval grain (the aspect ratio equal to ∼ 3).

Authors: Kapitan Dmitrii , Rybin Alexey , Andriushchenko Petr , Kapitan Vitalii , Vasiliev Egor , Nefedev Konstantin
Published: November 2020

It is well known that critical phenomena occur in condensed matter under certain conditions, when an abrupt change in its properties occurs. In the vicinity of critical points, various phenomena may arise. The critical region can be described by a set of state parameters (order parameters), which allow one to obtain information about the anomalous behavior of thermodynamic averages, internal processes, and the nature of the objects of study. The abnormal nonlinear behavior of state parameters is described by critical exponents. In this article, we considered spin glass on the example of the Edwards-Anderson model. For the simulation, the replica-exchange Monte-Carlo method was used. Critical exponents were obtained to describe the behavior of the model in the critical region.

Authors: Afremov Leonid Lazarevich , Anisimov Sergei , Iliushin Ilia
Published: November 2020

A theoretical study was made of the dependence of the blocking temperature of the core/shell system of nanoparticles on the intensity of their magnetostatic interaction. It is shown that with an increase in the concentration of nanoparticles (intensity of the magnetostatic interaction), the blocking temperature increases. Moreover, the of large nanoparticles changes more significantly.

Authors: Ahmadpour Ghader , Samardak Aleksey Yu. , Nasirpouri Farzad , Samardak A.S. , Ognev Alexey V.
Published: November 2020

Nanoparticles of Nd(Fe1-xCox)B with Co concentrations ranging from x = 0 to 0.5 were prepared using a modified Pechini-type sol-gel method. We have shown the influence of Co on the morphology and size of nanoparticles, as well as on elements distribution in nanostructures. It was found that nanoparticles with increased content of Fe and Co were formed during the synthesis process. There was an interdiffusion of Nd and Fe, both after oxidation and after reduction. This study helped to define promising “bottom-up” approaches for the fabrication of nanomaterials for the advanced Nd(Fe1-xCox)B permanent magnets by chemical synthesis.

Authors: Dermenji L. , Lisunov K.G. , Galkin Konstantin Nickolaevich , Goroshko Dmitrii L. , Chusovitin E.A. , Galkin Nikolay G. , Arushanov Ernest
Published: November 2020

Resistivity, r (T), and Hall coefficient in weak (B < 1 T) magnetic fields, R (T), are investigated in Ca2Si and CaSi2 films at temperatures T between ~ 20 - 300 K. In CaSi2, r (T) is typical of metals increasing with T within the whole temperature range. On the other hand, the resistivity of Ca2Si is pertinent of semiconductors. Namely, it is activated below T ~ 200 K, exhibiting different slopes of ln r vs. T -1 plots at lower and higher T, and a weak increase between T ~ 200 - 300 K. Both materials demonstrate a complex dependence of R (T), including a change of the sign. Transport properties above have been analyzed assuming two groups of charge carriers, electrons and holes, contributing them.
Relationship between the Photoluminescence Spectra and IR Spectroscopy of Mesoporous Silicon Samples during Long-Term Storage: The Effect of Immersion in an Aqueous Fe(NO3)3 Solutions
Authors: Galkin Nikolay G. , Yan Dmitrii Tkhyarbonovich , Galkin Konstantin Nickolaevich , Chusovotina Svetalana
Published: November 2020

The article provides a comparative analysis of changes in the PL spectra and infrared spectroscopy (IR) with reference and immersion samples of mesoporous silicon during long-term storage in air at room temperature. Immersion was carried out in an aqueous solution of iron nitrate (Fe (NO3)3) with a concentration of 0.2 M and 0.5 M with three times: 5, 10 and 20 minutes. An analysis of the FIR data for etalon and immersion samples showed a number of features found during long-term storage of mesoporous silicon: (1) a sharp decrease in the density of hydride bonds; (2) the polynomial nature of the growth of O3-SiH and Si-OH bonds saturating dangling bonds; and (3) the polynomial growth of silicon dioxide with the formation of oxygen defects. It was found that after immersion in a solution of 0.5 M Fe (NO3)3 for 10 minutes, a more intense increase in the PL in mesoporous silicon is observed while maintaining its nanostructure after 200 days of storage compared with the etalon sample, for which a weak quantum size confinement (QSC) is observed. The main mechanism of photoluminescence increase in mesoporous silicon during long-term storage is radiative recombination from oxygen defect levels, not from a QSC effect.
Effect of Process Temperature on the Growth Kinetic and Structure of Ge Nanowires Formed by Galvanostatic Electrodeposition Using in Nanoparticles
Authors: Gavrilin Ilya
Published: November 2020

In this work, germanium nanowires (GeNWs) were fabricated by galvanostatic electrodeposition using In nanoparticles from water solutions at different temperatures. It was found that in the temperature range from 10°C to 60°C there was no significant change in the structure of GeNWs, and the average diameter was about 40 nm. The growth time of GeNWs increases linearly with increasing temperature of the electrolyte solution. However, the structure of GeNW obtained at a solution temperature of 90°C has changed. It was shown that these GeNWs have a core-shell structure: the core is a crystalline Ge phase containing In atoms, and the shell is Ge oxides (hydroxides).

Published: November 2020

We investigate the effect of the Adige-Garda spillway opening on the 03/03/2020 on Lake Garda using numerical modelling and maps of Suspended Particulate Matter (SPM) concentration. SPM maps are obtained from Sentinel-2 images processed using the BOMBER bio-optical model. Three satellite images are examined: 28/02/2020, 04/03/2020 and 07/03/2020. Maps indicate a significant increase in SPM concentrations, especially in the northern part of the lake close to the hydraulic tunnel outlet. Results are consistent with the modelled flow field. Remote sensing effectively captures the event’s spatial and temporal variation, while numerical modelling explains and corroborates the observed patterns.
Problems of New Abortion Legislation in Germany.
Authors: Starck Christian
Published: November 2020

The article points out the inadequate protection of an unborn child under the German abortion legislation. In the light of the constitutional prerequisite, that unborn human life enjoys human dignity which has to be protected by the state, it emphasises that the Federal Constitutional Court accepted the counselling-based model passed by the legislature under the condition that the counselling is carried out in good faith with the purpose to defend the life of the unborn child.

In an analysis of the abortion legislation the author outlines several lacks in the legislation compared to the requirements given by the Court. Furthermore, these requirements were undermined by the admission of the abortion drug mifepristone in 1999. As time constraints arise, if a pregnant woman intends a medicated abortion by using mifepristone, she is prevented from seriously attending the counselling. For this reason the minimum level of unborn life protection established by the Court would be breached clearly now and the legislature is asked by the author to amend the protection for the life of the unborn child.
Il trattamento del cancro polmonare: evidenze scientifiche e valori bioetici in conflitto nelle scelte terapeutiche
Authors: Toraldo Domenico Maurizio
Published: November 2020

Il cancro del polmone costituisce una delle principali cause di morte dei paesi europei. La malattia se inoperabile ha una prognosi generalmente infausta e circa l’80% dei pazienti muore entro un anno dalla diagnosi. Stabilire un efficace piano di trattamento costituisce una priorità di salute pubblica e oggetto di continuo dibattito scientifico.

La diagnosi precoce offre la possibilità al malato di usufruire del trattamento chirurgico che può guarire la malattia. La polichemioterapia e la radioterapia si rivelano spesso fallimentari e nel migliore dei casi possono allungare di qualche mese la vita del malato al costo di sofferenze importanti.

Nella pratica clinica in molti ospedali italiani pur non esistendo un protocollo diagnostico-terapeutico di riferimento, e il trattamento medico viene proposto, nella maggior parte dei casi, senza un adeguato consenso informato che spieghi al paziente le difficoltà e la complessità terapeutiche ed il paziente nella maggior parte dei casi non partecipa alle decisioni che lo riguardano.

L’Autore attraverso una revisione della letteratura scientifica recente mette a punto il problema dal punto di vista tecnico e affronta contestualmente i numerosi problemi bioetici e deontologici sollevati dall’assenza sia di un’etica della comunicazione nelle problematiche della diagnosi e della terapia sia della relazione di cura cioè nella conduzione della terapia nel tempo, mettendo in evidenza le inesauribili possibilità curative che il medico dovrebbe evidenziare con la su presenza e con il suo attaccamento al malato.

Viene analizzato il ruolo decisivo del medico nelle ultime fasi della vita del paziente e l’utilità della medicina palliativa nella sedazione del dolore e nel controllo dei sintomi come forma di rispetto della dignità della persona. Infine l’Autore auspica la necessità di una formazione etica e deontologica attraverso corsi di aggiornamento obbligatorio del medico ospedaliero per poter acquisire una consapevolezza dei valori in gioco.
Some Remarks Concerning the Embryos Bill of the Dutch Government
Authors: Eijk Willem J.
Published: November 2020

After many years of delay the actual Dutch government has presented a detailed bill regarding embryo experiments, which has recently been passed by Parliament, but still has to be discussed in the senate. While permitting research with rest embryos for medical-biological ends, it forbids, albeit for the time being, creating embryos solely for the purpose of research. The bill includes, however, the possibility to decide after three to five years by Royal Decree that embryos may also be created only for scientific research. A few articles which will then be effective are already written into the bill. It has thus been stipulated beforehand the embryos especially created for scientific purposes may only be used for research concerning infertility, artificial reproduction, congenital abnormalities and transplant medicine.

The government has proposed the permission of experiments with rest embryos and a temporary prohibitions of creating embryos solely for research taking into account four factors: respect for human life, the interest of medical science, the social acceptability of the creation for solely research in the Netherlands and that abroad. The original idea of possibly allowing after five to seven years the modification of the genetic material of the nucleus of germ cells has been abandoned in line with the 2001/20/EC European Directive regarding the mutual harmonisation of provisions concerning medical research.

Room is however left for the ‘in vitro nuclear transplantation’ (or better cytoplasm transplantation) for the treatment of mitochondrial disorders. After that the creation of embryos for other purposes than pregnancy will have been allowed, cloning will be permitted for transplant medicine, but not for the production of a series of genetically identical individuals. The fusion of human and animal gametes is only permitted if the resulting being will not reach multicellular stage. According to the bill it is permitted to create chimeras by combining human with other human or animal embryos with a view to investigating human embryonal development, provided that the resulting chimera will not be kept alive longer than two weeks. The bill is here discussed from the perspective of catholic morla doctrine and international conventions.

Authors: Berger Yael , Gingold-Belfer Rachel , Khatib Muhammad , Yassin Mostafa , Khoury Wisam , Schmilovitz-Weiss Hemda , Issa Nidal
Published: November 2020

Background:

Transanal endoscopic microsurgery (TEM) is considered the procedure of choice for rectal adenomas non-amendable for endoscopic excision and for early rectal cancer. TEM may gain more importance in patients who are considered unfit for major surgery. The option of spinal anaesthesia may offer many advantages for patients undergoing TEM while maintaining the principles of complete tumour excision. The aim of this study is to report the outcome of patients undergoing TEM under spinal anaesthesia.

Methods:

Demographic and clinical data pertaining patients undergoing TEM under spinal anaesthesia between 2004 and 2015 were retrospectively collected.

Results:

A total of 158 TEM procedures were recorded in the study period. Twenty-three patients (15%) underwent the procedure under spinal anaesthesia and were included in the study; 13 of them were male and ten were female. The mean age of the patients was 69.1 ± 10.6 years. Seventeen (74%) rectal lesions were adenomas, two (9%) were adenocarcinoma and four (17%) had involved margins after polypectomy. The mean tumour size was 2.1 cm (range, 0.5–3). Distance from the anal verge was 7.7 ± 2.2 cm. Seventeen (74%) lesions were in the posterior wall. The operative time was 73 min (range, 46–108) No adverse anaesthesia-related events were recorded, and the post-operative pain was reduced. The median time of hospitalisation was 2 days (range, 1–4). No major complications were noted, and the minor complications were treated conservatively. The surgical margins were free of tumour in all cases.

Conclusion:

TEM under spinal anaesthesia had short duration of surgery, no increase in operative and post-operative complications or hospital length of stay. Avoiding the use of general anaesthesia, in such challenging procedure, may open new opportunities for patients determined to be unfit for general anaesthesia.

Published: November 2020

INTRODUCTION: Diabetic nephropathy is one of the complications of diabetes that causes damage to kidneys. Deep learning techniques are widely used to predict different diseases.OBJECTIVES: The main aim of this work is to develop an effective prediction model using deep learning. To get an effective model, a suitable dataset is considered that comprises of features related to diabetic nephropathy.METHODS: Deep belief network (DBN) is the proposed deep learning technique which is compared with naive bayes, CART decision tree, logistic regression and support vector machine. DBN is composed of Restricted Boltzmann Machines (RBM). The algorithms are analysed based on evaluation measures like area under PR curve, area under ROC curve, gini coefficient and jaccard index.RESULTS: After comparison of all algorithms, it was observed that DBN has performed better in terms of AUROC, gini coefficient and jaccard index with values 0.8203, 0.6406 and 0.7777 respectively. But CART obtained better value of 0.9039 only for AUPR.CONCLUSION: The proposed technique has outperformed other techniques in terms of three metrics and is identified as the best performing algorithm. Hence, it is suggested to use DBN while predicting diabetic nephropathy.

Authors: Christmas Colleen , Dunning Kathy , Hanyok Laura A. , Ziegelstein Roy C. , Rand Cynthia S. , Record Janet D.
Published: November 2020

Background

A novel patient-centered curricular experience was implemented in an internal medicine residency program in 2007. There is little published evidence that what is taught in residency affects practice after graduation.

Objective

We sought to evaluate whether graduates perceived any long-term effects of participation in this patient-centered curriculum.

Methods

From July to September 2015, a web-based survey with quantitative and qualitative components was sent to graduates of the program to assess self-reported effects of this curriculum on current practice. Graduates spent 2 to 8 weeks on the intervention team during their training. Responses to open-ended questions were independently coded by 2 investigators, using the editing analysis method. Emergent themes and representative quotes are reported.

Results

Of 150 residents who completed at least 1 year of training from 2007 to 2014, 94 of 110 (85%) with available email addresses responded to this survey. Of respondents, 21 (22%) were still in fellowship training, and 71 (76%) were in full-time practice. The majority responded “a great deal” when asked if the experience was valuable to their training as a physician (72 of 94, 77%) or influenced their practice (59 of 94, 63%). Free-text comments indicate that residents felt the experience enhanced their understanding of social determinants of health, communication skills, relationship building, and ability to tailor treatments to individual patients.

Conclusions

Internal medicine residency graduates reported that exposure to a curriculum focused on knowing patients as individuals had important enduring effects on their practice.

Authors: Okicic Melisa , Kalajdžisalihović Nejla , Djuliman Selma , Sadikovic Amira
Published: November 2020

In the present paper, the authors analyse attitudes of students (N=91) studying at the Department of English Language and Literature toward distance learning launched at the Faculty of Philosophy, University of Sarajevo, during the COVID-19 pandemic in March 2020. The study is designed as action research containing elements of both qualitative and quantitative research. The key instrument for collecting data was a survey designed by the authors of the present paper. The Google Forms survey was delivered to 1st-5th year students at the Department of English Language and Literature by e-mail. The collected data were processed by means of SPSS software (descriptive statistics). Results of the analysis show that students do not consider “distance learning’’ to be of better quality when compared to “learning in the classroom’’ but also that students, in the period of returning to a “new normal’’, openly express their preference for blended learning. At the same time, results of the analysis reveal that it is necessary to modernise teaching practices by means of introducing a more representative version of the distance learning system that would not only significantly improve the quality of the teaching practices, but also assist in maintaining competitiveness of the Faculty of Philosophy as a higher education institution.
L’INSEGNAMENTO DELLA COMPETENZA PRAGMATICA / TEACHING PRAGMATIC COMPETENCE
Authors: Lalic Ana
Published: November 2020

This paper aims to analyze the possibility of a diachronic approach to pragmatic competence in a foreign language. The main objective of the paper is to examine the methods that were used by the authors of grammar books published before the 20th century with the goal of ascertaining to what extent it was possible to teach pragmatic competence. The main hypothesis is that methods for teaching pragmatic competence existed even before the 20th century, but that complex theories and methodologies did not. To that end we adapt the modern speech act theory as a framework for analysis of grammars for foreigners, I analyze the historical profile of the foreign language learner, and I individualize possible language needs in a diachronic perspective. The central part of the research consists of a qualitative analysis of speech acts from Casotti (1709) and of the analysis of their communicative role. The results implied by this research can further be used for research in the field of didactics – both historical and modern – and that of historical linguistics, more specifically historical pragmatics.
O NASTANKU ITALIJANSKOG JEZIKA I SPECIFIČNOSTIMA ODNOSA STANDARDNI JEZIK - DIJALEKTI / ON THE ORIGIN OF THE ITALIAN LANGUAGE AND SPECIFICITIES OF THE RELATION BETWEEN THE STANDARD LANGUAGE AND DIALECTS
Authors: Kerla Nerma
Published: November 2020

The subject of this paper is the relation of the standard Italian language to the dialects present on the territory of Italy. In the first part of the paper, we will focus on the basic concepts such as the difference between the standard language and dialects, on the prestige it has in comparison to dialects, as well as on linguistic varieties. Since the issue of language is often related to socio-historical aspects, in the second part of the paper we will look at the development of the Italian language and its role in raising awareness of national identity. We will then explain the concept of dialect and see that, specifically on Italian soil, dialectal differences can as considerable as to prevent communication within the same language. We will briefly look at some Italian dialects, such as Venetian, Sardinian and Neapolitan, and the status they enjoy. We will also mention contemporary attitudes about the use of dialects in Italy and some of the tendencies of the modernItalian language.

The development of science and technology and their application in society, led to
the overcoming of traditional models of learning and the introduction of new,
innovative teaching models. Contemporary teaching of physical education is based on
interdisciplinarity, which is a good basis for even greater application of new learning
models, especially the project based learning. The project based learning puts students at the center, so that, through the realization of the project, they develop their own
competencies. The aim of the paper is to present the results of the research in the
teaching of physical education, in which project teaching is applied, as well as the
interdisciplinary physical education. The work is based on a review of the relevant
literature, i.e. analysis of the results of the research of the same. For the search of foreign works, the base of the academic journals JURN, ЕRIC, EBSCO, Taylor & Francis,
Research Gate, which includes research in the field of social sciences was used. The
advantages of applying the project model, the recommendations for applying it in teaching of physical education, and the increase in the number of research on the subject are highlighted.

O presente estudo objetivou identificar se as corporações listadas no Brasil, Bolsa, Balcão (B3) demonstram seguir as regras necessárias para estarem enquadradas dentro de cada nível de governança corporativa. Trata-se de uma pesquisa descritiva e explicativa, utilizando-se de pesquisa bibliográfica, documental e de campo por meio de observação nas páginas eletrônicas de Internet de 346 corporações. Constatou-se a existência de algumas corporações em desconformidade com a totalidade das exigências da B3, necessárias para mantê-las enquadradas dentro dos respectivos níveis de governança corporativa, como por exemplo o baixo cumprimento da exigência de adesão à câmara de arbitragem do mercado. Destaca-se que este estudo não observou a totalidade de corporações listadas na B3 e nem em outros meios de divulgação. Nesse sentido, sugere-se que em pesquisas futuras sejam observados outros meios de evidenciação como os relatórios anuais e complementares, bem como outras corporações listadas. Também, se sugere que sejam feitos estudos semelhantes em outros países para efetuar comparações com os resultados desta pesquisa

Problemas de otimização têm como foco principal encontrar uma solução viável entre alternativas possíveis. O Traveling Salesman Problem (TSP) pertence a esta classe de problemas. No entanto, devido a existência de uma variada pluraridade de dimensões e variáveis, as quais compõe o TSP, não é possível encontrar sua solução viável em um tempo polinomial definido. E, é por isso, que é considerado um dos problemas difíceis de NP-hard. Por esses motivos, apresentamos proposta de um Genetic Algorithm (GA) híbrido para resolução do Traveling Salesman Problem (TSP), no qual o operador de crossover é empregado em uma aplicação local. Esta aplicação obteve soluções adequadas para um ambiente urbano, com um tempo computacional aceitável para o TSP, integrando o GA e as condições ambientais locais. Os resultados experimentais ilustram que a proposta apresentada além de atender as condicionantes locais da unidade de pesquisa, também, pode ser utilizada em outras situações, sendo parametrizável e adaptável a outros algoritmos genéticos, fornecendo com isso, precisão e eficiência satisfatória no processamento real da otimização.

Abstract

Objective: To determine the effect of Ivabradine in lowering heart rate and quality of life in chronic heart failure patients.

Methods: The observational study was conducted in the out-patient department of the National Institute of Cardiovascular Disease, Karachi, from December 2016 to June 2017, and comprised chronic heart failure patients aged 30-70 years who were on 5mg Ivabradine for 8-weeks. Heart rate was evaluated through electrocardiogram, and health-related quality of life was measured using the validated questionnaire. Baseline demographics and clinical characteristics were recorded, with follow-ups at week-4 and week-8. Safety and tolerability were assessed by adverse drug reactions monitoring. Data was analysed using SPSS 21.

Results: Of the 50 patients, 34(68%) were males. The overall mean age was 54.8±9.17 years. Baseline mean heart rate significantly reduced at first and second follow-up visit (p< 0.001). Mobility problems declined significantly as well (p<0.05). Health-related quality of life significantly improved on follow-up visits (p<0.001).

Conclusion: There was significant control of heart rate in chronic heart failure patients with improvement in all parameters of quality of life.

The aim of this study was to determine the effect of Moringa oleifera leaf extract supplements, Moringa oleifera leaf extract plus royal jelly and placebo on hemoglobin levels in anemic pregnant women. This research is a randomized controlled double blind design study which was conducted in Polombangkeng Utara District, Takalar Regency for 2 months. The subjects of this study were pregnant women with anemia, the majority of which were 20-35 years old, primigravida parity, income less than UMR, unemployment, higher education, pregnancy distance of more than 2 years with p value> 0.05. Then divided into three groups, namely Moringa capsules plus royal jelly (KRJ) (n = 24), Moringa capsules (KTR) (n = 24) and placeco (PLC) (n = 21). Before and after the intervention, measurements of hemoglobin levels were carried out using the Hemocue tool and interviewing the characteristics of the respondents. The results showed that the average Hb level increased from each group (mean SD): KRJ 10.06 ± 0.75 to 11.42 ± 1.23, P = 0.001, KTR 10.40 ± 0.46 to 11.15 ± 0 , 90 P = 0.001 and PLC 10.43 ± 0.42 becomes 11.14 ± 0.88 P = 0.002. but there was no significant difference from the difference in the average increase in Hb levels in the three groups, but there was a tendency that KRJ was superior to the KTR and PLC groups with an increase of 1.36 gr / dl, KTR 0.75 gr / dl and PLC 0.71 gr / dl. So it can be concluded that KRJ is better than KTR and PLC in increasing Hb levels in anemic pregnant women in Takalar Regency.

Authors: Arámbulo Ayala Marizol Candelaria
Published: November 2020

Objetivo: Proponer un modelo de medición del capital intelectual que permita diagnosticar su influencia en la competitividad de las empresas agroexportadoras de Tacna.

Método: Se realizó una revisión teórica de los diversos enfoques acerca del capital intelectual y de la competitividad, que permitió diseñar una metodología basada en los indicadores propuestos para la medición. Debido a las características de la investigación, el cuestionario se presenta como la herramienta más apropiada para obtener información específica. Son pocos los trabajos que han estudiado el capital intelectual en su totalidad, de modo que se han seleccionado e integrado indicadores de medición procedentes de diversas fuentes. Se han formulado una serie de preguntas relacionadas con las variables considerando que el número de preguntas fuera idóneo para dicha aplicación. Se realizaron las funciones típicas del flujo de procesamiento de datos, se aplicó el análisis factorial exploratorio a cada una de las escalas de medición del modelo, con sus respectivas pruebas y medidas estadísticas, cuyo resultado fue la identificación de los factores de cada componente con sus respectivas cargas factoriales. Adicionalmente, se aplicó el análisis de regresión para diagnosticar el comportamiento de la competitividad a partir del capital intelectual.

Resultado: El modelo de medición consta de 24 indicadores de escala para capital intelectual y 9 para competitividad; y se comprueba que el conjunto de activos del capital intelectual ejercen una influencia positiva en la competitividad.

Conclusiones: Los resultados han permitido constatar el valor estratégico del capital intelectual de su conexión con la competitividad.
