Authors: Martínez Guadarrama Gustavo , Robles Estrada Erika , Oudhof Van Barneveld Johannes , Zarza Villegas Susana Silvia , Villafaña Montiel Lourdes Gabriela
Published: December 2019

El objetivo de esta investigación fue construir una escala válida y confiable que midiera las habilidades parentales en padres y madres. Se trabajó con 341 hombres y 341 mujeres de la ciudad de Toluca con hijos entre 6 a 12 años de edad. Con base en las siguientes habilidades: educativas, de agencia parental, de autonomía y apoyo social, vida personal y de pareja, y organización doméstica (Rodrigo & Máiquez, 2008). El procedimiento que se llevó a cabo fue someter el instrumento preliminar a validez de jueces; posteriormente, se llevó a cabo un pilotaje y la aplicación final del instrumento de forma colectiva. El procesamiento de la información para la validez se realizó mediante un análisis factorial exploratorio de tipo ortogonal con rotación varimax y, para la confiabilidad, el alpha de Cronbach. De acuerdo con los resultados, en el instrumento de hombres se obtuvieron 8 dimensiones; en el instrumento de mujeres se encontraron 5. En ambos padres se encontraron habilidades de afecto, acuerdos en la pareja, limpieza y seguridad, estimulación y desarrollo y autoeficacia parental. Los padres presentaron tres más: afecto, solución de problemas y adaptación a las características del menor. Ambas escalas son válidas y confiables, de tal manera que se concluye que ambos padres consideran importantes todas las habilidades en la crianza cotidiana, las cuales son esenciales para el desarrollo biopsicosocial de los niños.

Published: December 2019

El objetivo del presente estudio fue diseñar y validar una prueba sobre estrategias de aprendizaje en un contexto de ejecución a partir de un modelo multidimensional de evaluación. A través de un Análisis Cognoscitivo de Tarea (ACT), se determinaron los tipos de contenidos a ser evaluados y las operaciones cognoscitivas que subyacen tras el aprendizaje del contenido del texto Estrategias para aprender a aprender de la materia del mismo nombre, de una universidad pública del noroeste de México. A partir de los resultados del ACT, se elaboró una prueba de Estrategias Para el Aprendizaje (EPA) constituida con 28 reactivos, la cual se aplicó a una muestra intencional de 144 estudiantes de licenciatura. Un análisis Rasch dio como resultado una prueba de 26 reactivos, posteriormente, se realizaron análisis factoriales confirmatorios, por medio de modelamiento por ecuaciones estructurales, por tipos de conocimientos (declarativo y procedimental) y por contexto de ejecución (reconocimiento y recuerdo); se obtuvieron dos modelos con ajuste adecuado a los datos de acuerdo con los índices más aceptados. Los estudiantes de ingeniería obtuvieron un mayor desempeño en la prueba EPA al ser evaluados en el contexto de recuerdo, en comparación con los de psicología.
La ciudad como categoría estética e ideológica en Cartas de relación de Hernán Cortés y Grandeza mexicana de Bernardo de Balbuena
Authors: Navarro Gálvez Jesús Abad
Published: December 2019

Con una reflexión de la ciudad como categoría operativa en el análisis literario se abre la posibilidad de pensar de dos maneras distintas a la ciudad. Primero, desde la perspectiva que le da la panorámica como un todo, la ciudad aparece como la versión oficial de esa selva de construcciones organizadas racionalmente para poder ser manipuladas por los órganos de control. Desde la otra perspectiva, desde una enunciación peatonal, aparece la ciudad real, la que es espacializada por los recorridos de la anterior enunciación. Los ejemplos utilizados en relación a estas ideas son la "Segunda carta de relación" de Hernán Cortés y Grandeza Mexicana de Bernardo de Balbuena. Ambos hacen referencia a la ciudad de México en dos épocas distintas que distan un siglo una de otra.

Proceso de transversalización de la perspectiva de género en la Universidad Autónoma de Ciudad Juárez. Avances y obstáculos
Authors: Ortega Ayala Lorena
Published: December 2019

La transversalización de la perspectiva de género en Instituciones de Educación Superior (IES), planteada como objetivo para el desarrollo sostenible desde la UNESCO (Organización de las Naciones Unidas para la Educación, la Ciencia y la Cultura, por sus siglas en inglés), es un compromiso para “una educación inclusiva, de calidad y aprendizaje a lo largo de la vida para [todas y] todos” (UNESCO, 2015, p.3). En México, las IES se han comprometido a articular esfuerzos y promover dicho objetivo en el interior de sus estructuras; sin embargo, el camino no ha sido sencillo (Buquet, 2011). En Ciudad Juárez –ciudad marcada por períodos de violencia extrema, particularmente hacia las mujeres– la Universidad Autónoma de Ciudad Juárez (UACJ) tiene un rol y deber relevantes para la transformación de las relaciones de desigualdad entre mujeres y hombres. Aquí se presentan algunas acciones implementadas por dicha universidad, sus avances y obstáculos.
SOME ASPECTS OF MECHANISM OF SUCCINAMIDES INFLUENCE ON METABOLIC HOMEOSTASIS OF THE ORGANISM
Authors: Palagina I. A.
Published: December 2019

Succinate containing compounds possess many types of biological activity and are used for the development of drugs with the target and complex action. This paper is devoted to some aspects of the mechanism of succinamides’ action in a dose of 100 mg/kg. We studied the influence of the compound with antidiabetic properties, -phenylethylamide of 2-oxysuccinanyl acid ( -PhEA-OSAA), and its metabolites such as 2-hydroxyphenylsuccinamide (2-HPhSA) and β-phenylethylsuccinamide ( -PhESA) on the marker indicators of energetic metabolism (EM), antioxidant system (AOS) and nitric oxide (NO) metabolism in subacute experiment on rats. Studies have shown that the action of -FEA-OSAKA on metabolic homeostasis is realized through stimulation of EM, reduction of intensity of NO-synthase metabolism and weakening of the AOS. The nature of the action of -FES and 2-GFS, taking into account the indicators of the state of homeostasis, largely coincides with β-FEA-OSAKA. It was found that the key links in the mechanism of toxic action of succinamides are the effect on antioxidant potential, NO metabolism and energy processes.

Published: December 2019

Due to the widespread of smoking and accessories for it many teenagers in the world and in our country inhale gas for lighter refills (butane) – this phenomenon is called «sniffing». In some cases sudden death occurs at intensive actions. It is connected with the fact that butane is inhalation drug and sensitizes a myocardium to arrhythmogenic effects of catecholamines. In experiments on rats the arrhythmogenic and secondary ischemic effect at butane inhalation has been shown. Death occurs as a result of sudden arrhythmias.

Published: December 2019

The effect of metals chlorides (cobalt, manganese, iron, lead, cadmium and copper) at wide range of concentrations on various aspects of the life of starfishes Asterias rubens has been studied. The experiments included a survival and behavioral responses (righting time) evaluation of starfishes during the seven-day exposure. Copper is the most toxic of the studied metals (half-lethal concentration LC50 = 0,062±0,01 mg/L, 96 hours of exposure), then toxicity decrease in the following order: lead (LC50 = 1,99±0,08 mg/L), cadmium (LC50 = 1,6±0,1 mg/L), cobalt (LC50 = 57,7±2,1 mg/L), manganese (LC50= 79,7±4,3 mg/L). Iron at studied concentrations did not influence the starfish’s survival. Copper, lead and cadmium led to a significant increase of the righting time after 96 hours of exposure. The toxic effects of these metals, except for copper, were revealed at higher concentration then Russian norms for surface waters.

Published: December 2019

The article presents the results of determining the level of expression of genes encoding GABA receptor subunits GABRA1, GABRB2, and GABRG2 in the hippocampus of rats 24 hours after a single intramuscular administration of the antagonist of the chloro-ion channel of GABA receptor of kloflubicin in a dose of LD25, LD40, LD50, and LD75. It is revealed that kloflubicin has no influence on the relative level of GABRG2 gene expression. At the same time, the relative level of GABRA1 gene expression increases 7,5, 7,0, and 5,0 times after administration of kloflubicin in a dose of LD40, LD50, and LD75, respectively. The relative level of GABRB2 gene expression also increases 3,6 and 2,6 times after administration of kloflubicin in a dose of LD50 and LD75, respectively. It is assumed that increase in the level of gene expression of GABRA1 and GABRB2 in rats after administration of kloflubicin in doses above LD25 is a compensatory reaction of the body to the effect of physiologically active substance, and subunits encoded by these genes α1 and β2, respectively, are included in the mechanism of convulsive effect.

Published: December 2019

The article presents the analysis of modern data and the history of the development of normative documents regulating the content of arsenic in drinking water in Russia and other countries. The comparative characteristic of arsenic rationing in drinking water on a global scale and in the context of individual countries is given. The absence of uniform requirements for arsenic content in drinking water in the current regulatory documents of Russia is noted. In terms of harmonization of the regulatory framework with international requirements, it is recommended to bring SanPin 2.1.4.1074-01 «Drinking water. Hygienic requirements for the quality of water of centralized systems of drinking water supply. Quality control.» to GN 2.1.5.1315-03 «Maximum permissible concentration of chemicals in water of water facilities used for commercial, household, and recreational purposes».

TOXIC PULMONARY EDEMA BY INHALATION OF PYROLYSIS PRODUCTS OF CHLORINATED PARAFFIN-70 IN RATS
Authors: Tolkach P. G. , Basharin V. A. , Chepur S. V.
Published: December 2019

In the study conducted on laboratory animals (rats) toxic pulmonary edema (TPE) was simulated by inhalation of pyrolysis products of chlorinated paraffin-70 (CP-70). The average-lethal dose of CP-70 burned at 280 ÷ 350 ° C for 3 minutes is 8.1 ± 0.9 g and provides a concentration of hydrogen chloride (HCl) in the chamber at the level of 7325 [5850; 8460] ppm. Under these conditions exposure for 30 minutes led to an increase in the pulmonary rate (LC) in laboratory animals 24 hours after poisoning. The diagnosis of TPE was confirmed histologically by the signs of interstitial and alveolar edema, as well as arterial hypoxemia (TI = 204.5 [180; 228]) indicating respiratory failure. The death of animals was recorded 3 days after application of the pyrolysis products of CP-70. The simulated experimental TPE model can be used to search for the means of pathogenetic therapy of pulmonary toxicants poisoning.

Published: December 2019

Aromatic volatile organic compound (VOC) sensors are attracting growing interest as a response to the pressing market need for sensitive, fast response, low power consumption and stable sensors. Benzene and toluene detection is subject to several potential applications such as air monitoring in chemical industries or even biosensing of human breath. In this work, we report the fabrication of a room temperature toluene and benzene sensor based on multiwall carbon nanotubes (MWCNTs) decorated with gold nanoparticles and functionalised with a long-chain thiol self-assembled monolayer, 1-hexadecanethiol (HDT). High-resolution transmission electron microscopy (HRTEM) and Fourier transform infrared spectroscopy (FTIR) were performed to characterize the gold nanoparticle decoration and to examine the thiol monolayer bonding to the MWCNTs. The detection of aromatic vapours using Au-MWCNT and HDT/Au-MWCNT sensors down to the ppm range shows that the presence of the self-assembled layer increases the sensitivity (up to 17 times), selectivity and improves the response dynamics of the sensors.

Published: December 2019

Herein, we report a mild and efficient palladium-catalyzed C–H functionalization method to synthesize a series of benzoquinone (BQ)-based charge-transfer (CT) derivatives in good yields. The optoelectronic properties of these compounds were explored both theoretically and experimentally and correlations to their structures were identified as a function of the nature and position of the donor group (meta and para) attached to the benzoquinone acceptor. Compound 3, where benzoquinone is para-conjugated to the diphenylamine donor group, exhibited thermally activated delayed fluorescence (TADF) with a biexponential lifetime characterized by a prompt ns component and a delayed component of 353 μs.
NONFINANCIAL PERFORMANCE EVALUATION AS SIGNIFICANT AREA OF STRATEGIC BUSINESS MANAGEMENT
Authors: Hornungová Jana
Published: December 2019

The main aim of this paper is to provide the answer to the questions: Which areas of the company play an important role in the evaluation of the performance? Which areas are considered to be important? Due to the fact that the business environment is constantly changing, changes also occur in the trends relating to performance. Traditional financial performance measures have been highly criticized and the need identified to integrate non-financial perspectives, such as the level of innovation, degree of motivation, intellectual capital, and other criteria. Intellectual capital is often a crucial factor in the creation of value in a company. Based on the research, employees and customers are one of the most important areas in the companies from the selected area. At the same time, dependence among these company’s areas and company’s profit has been identified. Furthermore, it has been found whether the introduction of social responsibility into business strategy affects responsible behaviour just in the working environment (as this is geared specifically to employment area). Thus, as regards business strategy and support to work environment, in this case no relationship has been indicated, therefore it is not possible to say that if companies apply social responsibility strategy, they support mainly the working environment.

Published: December 2019

We present 81 near-infrared (NIR) spectra of 30 Type II supernovae (SNe II) from theCarnegie Supernova Project-II(CSP-II), the largest such data set published to date. We identify a number of NIR features and characterize their evolution over time. The NIR spectroscopic properties of SNe II fall into two distinct groups. This classification is first based on the strength of the Heiλ1.083μm absorption during the plateau phase; SNe II are either significantly above (spectroscopicallystrong) or below 50 Å (spectroscopicallyweak) in pseudo equivalent width. However, between the two groups other properties, such as the timing of CO formation and the presence of Srii, are also observed. Most surprisingly, the distinct weak and strong NIR spectroscopic classes correspond to SNe II with slow and fast declining light curves, respectively. These two photometric groups match the modern nomenclature of SNe IIP, which show a long duration plateau, and IIL, which have a linear declining light curve. Including NIR spectra previously published, 18 out of 19 SNe II follow this slow declining-spectroscopically weak and fast declining-spectroscopically strong correspondence. This is in apparent contradiction to the recent findings in the optical that slow and fast decliners show a continuous distribution of properties. The weak SNe II show a high-velocity component of helium that may be caused by a thermal excitation from a reverse shock created by the outer ejecta interacting with the red supergiant wind, but the origin of the observed dichotomy is not understood. Further studies are crucial in determining whether the apparent differences in the NIR are due to distinct physical processes or a gap in the current data set.
Nonlinear Rossby Wave–Wave and Wave–Mean Flow Theory for Long-term Solar Cycle Modulations
Authors: Raphaldini Breno , Teruya André Seiji , Raupp Carlos F. M. , Bustamante Miguel D.
Published: December 2019

The Schwabe cycle of solar activity exhibits modulations and frequency fluctuations on slow timescales of centuries and millennia. Plausible physical explanations for the cause of these long-term variations of the solar cycle are still elusive, with possible theories including stochasticity of the alpha effect and fluctuations of the differential rotation. It has been suggested recently in the literature that there exists a possible relation between the spatiotemporal structure of the solar cycle and the nonlinear dynamics of magnetohydrodynamic (MHD) Rossby waves at the solar tachocline, including both wave–wave and wave–mean flow interactions. Here we extend the nonlinear theory of MHD Rossby waves presented in a previous article to take into account long-term modulation effects due to a recently discovered mechanism that allows significant energy transfers throughout different wave triads: the precession resonance mechanism. We have found a large number of Rossby–Hauwirtz wave triads whose frequency mismatches are compatible with the solar cycle frequency. Consequently, by analyzing the reduced dynamics of two triads coupled with a single mode (five-wave system), we have demonstrated that in the amplitude regime in which precession resonance occurs, the energy transfer throughout the system yields significant long-term modulations on the main ∼11 yr period associated with intratriad energy exchanges. We further show that such modulations display an inverse relationship between the characteristic wave amplitude and the period of intratriad energy exchanges, which is consistent with the Waldmeier law for the solar cycle. In the presence of a constant forcing and dissipation, the five-wave system in the precession resonance regime exhibits irregular amplitude fluctuations, with some periods resembling the grand minimum states.

Published: December 2019

We present the first regional inventory of the fauna of Chalcididae in the Peruvian Amazon, with a nearly 6-fold increase in the number of species recorded for the country. A total of 418 specimens of Chalcididae were collected between 2000 and 2017 at the Panguana Reserve, Peruvian Amazon, 400 of which were obtained using Malaise traps and the remaining 18 specimens by canopy fogging. The morphological analyses indicated that these specimens represent 183 species of Chalcididae in 10 different genera, with 173 new to Peru and 134 potentially new species. We submitted 268 specimens, representing 167 species, to DNA barcoding. Of these, 141 specimens yielded sequences, 136 of them with a minimum of 300 bp. Sixty specimens were assigned a BIN by the Barcode of Life Database System (BOLD), resulting in 50 BINs. A cluster analysis of 138 individuals that yielded DNA sequences longer than 100 bp revealed 118 MOTUs (molecular operative taxonomic units), all of them highly congruent with the morphological data. Prior to the present study, 37 species in 9 genera of Chalcididae were known from Peru. With our results, this number was increased to 210 species in 13 genera. The present study is the result of a joint effort between the SNSB - Zoologische Staatssammlung München, Germany (ZSM) and the Insect Biodiversity Laboratory of the Universidade Federal do Espírito Santo, Vitória, Brazil (LaBI-UFES), intending to apply an accelerated taxonomic treatment of the Chalcididae of the Panguana reserve using traditional morphological approaches in combination with DNA barcoding. The complete molecular dataset and associated voucher information is publicly available through BOLD. The new species that were discovered as part of the study are being formally described elsewhere as part of taxonomic treatments of Neotropical and world generic revisions at LaBI-UFES.
La régulation de la pertinence thérapeutique des essais précoces en cancérologie
Authors: Auroy Lola , Besle Sylvain , Schultz Émilien
Published: December 2019

Depuis quelques années, la participation à un essai clinique précoce pour des patients atteints de cancers avancés gagne en importance. La mise en avant des bénéfices thérapeutiques d’une participation pour les patients inclus pose la question de la régulation de la pertinence du recours à ces essais comme soin en dehors des cadres législatifs des médicaments. Cet article montre, à partir d’une série d’enquêtes sur la recherche précoce en cancérologie, que cette régulation est largement issue des professionnels de santé tout en étant contrainte par la disponibilité des essais, sujette, quant à elle, à une régulation économique et scientifique de la part des industriels du médicament. Cette situation de régulation professionnelle sous contrainte a pour conséquences de limiter la possibilité d’établir des critères généraux de la pertinence comme soin des essais précoces au-delà d’une évaluation au cas par cas des parcours de patients.
An interim screening limit of detection for naproxen in equine plasma: a review and analysis

Published: December 2019

Starting in August 2015 Thoroughbred racing in Charles Town, West Virginia experienced a sequence of intermittent low concentration Naproxen identifications from 6.3 to 161 ng/ml of plasma (27.3 to 699 nM). These identifications were ongoing, indicating the horsemen were unaware of their origins. Naproxen is administered orally to horses at substantial doses and is chemically stable in the environment. These identifications are therefore most likely associated with exposure of these horses to environmental traces of Naproxen. Given the low concentrations of these identifications, we were asked to identify a Screening Limit of Detection (SLOD) below which these trace level Naproxen identifications would not be reported. Review of the data set suggested an SLOD of 200 ng/ml, while outlier analysis suggested an ‘extreme’ outlier level at 247 ng/ml, which figure was rounded up to 250 ng/ml Naproxen or 1.09 uM. This proposed SLOD is in good agreement with other US regulatory thresholds for therapeutic medications and this Interim Screening Limit of Detection was presented for review.

O valor da visita em uma ação de visitação: turismo de base comunitária, dinheiro e filosofia política sertaneja
Authors: Cerqueira Ana Carneiro
Published: December 2019

Em função de um episódio ocorrido durante uma ação de visitação promovida, em 2015, pelo Projeto de Turismo Ecocultural de Base Comunitária do Território Mosaico Sertão Veredas – Peruaçu, recupero dados coletados por uma pesquisa etnográfica realizada, entre 2006 e 2009, com o Povo dos Buracos, abrangido pelo projeto. No episódio, alguns agricultores recusavam-se a cobrar dinheiro a turistas que visitariam suas casas. Contrariamente, as coordenadoras da ação diziam ser necessário precificar a estadia dos turistas nas casas dos agricultores para que estes conseguissem gerar renda. Que espécie de relação outra com os turistas poderia ser desejada se não a da troca mercantil? Não se trata aqui de estabelecer externalidade entre dois mundos supostamente opostos, um dos laços comunitários, outro do mercado. O objetivo é indagar sobre como certas composições relacionais assumem maneiras específicas de lidar com o dinheiro. Por este caminho, ao final do artigo exploro a ideia de uma “filosofia política” presente nas práticas sertanejas de visita.

Published: December 2019

O estado de emergência em saúde pública decorrente da epidemia do Zika vírus no Brasil, especificamente na Região Nordeste e no Estado de Pernambuco, mobilizou o sistema de saúde, da assistência social, o campo científico e jurídico, num esforço conjunto para responder à população e as agências internacionais sobre o nascimento de crianças com microcefalia (Síndrome Congênita do Zika Vírus - SCZ). Neste artigo, fazemos uma análise do Benefício de Prestação Continuada – BPC, a partir da lei que priorizou o seu acesso a crianças acometidas pelo Zika Vírus no Instituto Nacional do Seguro Social – INSS. A partir do método etnográfico, buscamos compreender as particularidades relacionadas à Emergência em Saúde Pública e ao modelo social de deficiência, sob a influência do BCP, que entram em pauta para o entendimento da epidemia. Em seguida, abordamos como se dão as negociações dos diferentes atores do processo – famílias atingidas pela SCZ, INSS, judiciário – no acesso ou não ao BPC e evidenciamos que a deficiência tem sido relativizada em detrimento do critério da pobreza.
Justiça, Identidade e Juventude indígena urbana: um estudo sobre os processos organizativos na Cidade do México
Authors: Igreja Rebecca Lemos
Published: December 2019

Especialmente a partir dos anos 1990, grupos indígenas da Cidade do México criaram organizações como um meio importante para ter acesso às políticas públicas e às novas legislações em matéria indígena. A constituição dessas organizações, no entanto, confrontou-se com uma série de problemas, em grande parte resultantes da dificuldade do reconhecimento da identidade étnica desses grupos, devido à forma como a presença indígena na cidade e suas necessidades principais são consideradas. Esse reconhecimento é ainda mais questionado quando se trata dos jovens indígenas que estão na cidade. Um novo momento surge com a elaboração da nova Constituição da Cidade do México em 2018, que contempla vários direitos para as comunidades indígenas residentes, especialmente, o direito à autonomia jurídica e política. É sob a perspectiva da participação dos jovens nas organizações indígenas, especialmente com relação aos conflitos com a justiça do Estado, que apresento a reflexão sobre “ser indígena” no contexto urbano.
Crime et État-providence
Authors: Bonnet François
Published: December 2019

Depuis le début des années 1980, des enquêtes aux États-Unis et des comparaisons internationales ont établi, au niveau agrégé, que la protection sociale au sens large réduit les taux de criminalité. L’article entre dans le détail de ces travaux et s’appuie sur les développements récents en microéconomie pour montrer que le mécanisme agissant au niveau individuel est probablement l’effet-revenu : la redistribution évite aux pauvres de s’engager dans le type de criminalité qui est induit par le défaut d’opportunités sur le marché du travail légitime.
Debate de la práctica, un instrumento para la construcción de la carrera del ergónomo que traspasa las fronteras
Authors: Mestanza Mirtha , Cromer Damien
Published: December 2019

Desde este año, espacios de debate de la práctica de la carrera creada por y para jóvenes practicantes en ergonomía son implementados en Perú. Esta iniciativa parte del hecho que el ergónomo es un trabajador como otro, y que, a este título, es necesario dialogar sobre la acción que realiza cotidianamente para avanzar y construir su práctica futura. Si estos espacios están recientemente en Perú, éstos existen en Francia hace 5 años y son propuestos por la Comisión “Jeunes Pratiques en Réflexion” de la sociedad de Ergonomía de Lengua Francesa. En este artículo, proponemos contar su génesis, su funcionamiento y los objetivos de su desarrollo.
Trabajo, subjetividad y clínicas del trabajo : una aproximación al estado de su cuestión en el caso colombiano
Authors: Orejuela Johnny , Pérez María del Mar , Vásquez Andrés
Published: December 2019

El propósito de este trabajo es presentar un balance sobre la investigación alrededor de las clínicas del trabajo en el contexto académico colombiano. El valor de este estado de la cuestión es que ofrece la posibilidad de representarnos y ubicar en el mapa académico una perspectiva alternativa de la psicología de la salud ocupacional. Para cumplir este cometido se propone discutir tres aspectos relevantes : primero, hacer una aproximación inicial a las condiciones que caracterizan las clínicas como un abordaje clínico-crítica de la relación trabajo-subjetividad-salud laboral ; segundo, se indica como contexto predecesor : la investigación sobre la relación trabajo-subjetividad en Colombia, que en nuestro país ha sido generalmente abordado por el multicampo de la psicología del trabajo y las organizaciones. Posteriormente, se describe la progresiva emergencia e institucionalización de las clínicas del trabajo en Colombia (publicación, eventos, posgrados, tesis, etc.) en algunas universidades, principalmente de las ciudades de Cali y Medellín

Published: December 2019

Aortic abdominal aneurysm (AAA) is an uncommon etiology of disseminated intravascular coagulation (DIC). The authors report a case of an 81-year-old male patient who presented with hematuria, intraoral hemorrhage, melaenas and ecchymosis of the lower back and of the abdominal wall, after being medicated with etoricoxib for a back pain. During the study, an abdominal aortic aneurysm, which prolonged to the left common and internal iliac artery, was discovered. The diagnosis of AAA induced DIC was made. After endovascular aneurysm repair (EVAR), the patient’s hemorrhagic manifestations disappeared and the laboratory findings normalized. In conclusion, the state-of-the-art treatment of DIC is the elimination of the underlying disease; in this case, EVAR was proven to be effective in treating the aortic aneurysm and the AAA-related DIC.
The Restoration of History to Its Deserved Position in Nigeria’s Educational System: A Compelling Need Met?
Authors: Ajayi Adegboyega Isaac
Published: December 2019

In this study an attempt has been made to trace the travails of History as an academic discipline in the educational system of Nigeria from the colonial days to the present. In the process it was established that it suffered neglect and nearly went into extinction before it was restored into the primary and secondary school curriculum in 2017. And its teaching has since commenced in September 2018. The roles of critical stakeholders and other concerned bodies in the restoration process are discussed along with the government initiative that brought back History. Ordinances, government policy papers, conference and seminar papers, newspapers and other secondary materials that are broadly relevant are judiciously utilised to establish the indispensability of History in the school curriculum of any nation that aspires to grow and develop in a healthy atmosphere.Key words: Restoration, Government Response, Eclipse, Advocacy, Culture, Tradition, Military.
Ìgbò Language and Culture Yesterday, Today and Tomorrow
Authors: Ikonne Ugochi Happiness
Published: December 2019

In this paper, we are going to discuss the status of Ìgbò Language and Culture in the past (i.e. yesterday), presently, (i.e. today) and apparently predict the future (i.e. tomorrow) with the view to draw the attention of the Ìgbò to the level of neglect and endangerment the Ìgbò language and culture are facing. The Ìgbò language and culture would be reviewed from the pre literate era of the igbo to the present dispensation. It concludes that the Ìgbò should be encouraged to adopt a positive attitude towards their language and culture, speak the language and work with it, manifest their rich cultures and get their children to do the same. Beside these, certainly, there will be no Igbo language and culture tomorrow. Again, schools should be encouraged to implement the mother tongue/ language of the immediate community MT/LIC medium policy at the appropriate levels of education. The Ìgbò should shun and dismiss the fallacy that the Ìgbò language is not complete or defective of any language function. The Ìgbò should be proud to showcase the most conspicuous aspect of their culture which includes the language, naming system and mode of dress.Key words: Ìgbò Language, Ìgbò culture, yesterday and today
Effect of zinc sources on milk yield, milk composition and plasma concentration of metabolites in dairy cows

Published: December 2019

This study was conducted to evaluate the effects of different sources of zinc (Zn) on feed intake, milk yield, milk composition, and blood metabolites. Twenty-four dairy cows were randomly allocated to one of four treatments in a randomized complete block design. The treatments consisted of i) control diet (no zinc supplementation), ii) zinc oxide (ZnO), iii) zinc glycine (ZnGly), and iv) zinc nano (ZnN). The Zn sources were added to provide 60 mg of supplemental Zn per kg diet. There were no differences in dry matter intake, milk yield, bodyweight, and body condition score of the cows between treatments. Zinc supplementation in the form of ZnN and ZnGly decreased somatic cell count compared with the other treatments. The superoxide dismutase and plasma Zn concentrations in the cows provided ZnGly and ZnN were greater than those in the ZnO and control groups. No difference was detected between groups in biochemical and haematological parameters, except that blood urea nitrogen concentrations of cows supplemented with ZnGly and ZnN were less than for the ZnO supplemented and control cows. The results showed that nano and organic Zn sources in the diet of dairy cows were more suitable than inorganic Zn as supplements for dairy cows.Keywords: milk composition, milk production, metabolism, somatic cell count
Thyme (Thymbra spicata L.), rosemary (Rosmarinus officinalis L.) and vitamin E supplementation of laying hens
Authors: Cimrin T.
Published: December 2019

This study was conducted to determine the effects on performance, egg quality parameters and some serum profiles of vitamin E, thyme and rosemary extracts that were added to laying hen feeds. One hundred twelve 48-week-old Bovans-genotype white laying hens were used in the research. In the study, hens were randomly divided into four groups, each comprising of four replicates of seven hens. The first group was fed with the basal diet as a control. The other three groups were fed diets with 200 mg/kg vitamin E, with 1000 mg/kg thyme, and with 1000 mg/kg rosemary for eight weeks. As a result, vitamin E increased egg production statistically compared with feeds with plant extracts. Thyme-supplemented feed increased egg weight significantly. However, it reduced egg production. Rosemary supplementation generated profit by reducing the feed intake, but had a negative effect by reducing egg weight and egg production. The cholesterol level in the blood serum decreased with thyme supplementation. In addition, blood triglyceride level decreased at a statistically significant level with the supplementation of both thyme and rosemary. In the light of these results, it can be said that the supplementation of vitamin E, thyme and rosemary extracts has a positive effect on some performance parameters and animal health. Since healthier products are obtained from healthy animals, the use of these natural additives in laying hen feeds could be recommended after dose trials.Keywords: aspartate aminotransferase, cholesterol, egg production, feed intake, plant extract, triglyceride
