Authors: Hedayati M. , Niazmand S. , Hosseini M. , Baghcheghi Y. , Beheshti F. , Niazmand S.
Published: December 2017

Objectives. The objective of this study was to evaluate the effect of vitamin E on the oxidative stress parameters and antioxidant defense enzymes in the heart and aorta of 6-n-propylthiouracil (PTU)-induced hypothyroid rats. Methods. The animals were divided into 4 experimental groups: Group 1 (Euthyroid) received tap water, Group 2 (Hypothyroid) received 0.05 % of PTU in dissolved in their drinking water, Group 3 (PTU+Vit E) hypothyroid rats treated with vitamin E, and Group 4 (Euthyroid+Vit E). Vitamin E was injected daily (20 mg/kg) to groups 3 and 4 via daily gavage for 6 weeks. Malondialdehyde (MDA) levels, total thiol levels, and the activities of Cu, Zn-superoxide dismutase (SOD) and catalase (CAT) were evaluated in the aortic and cardiac tissues. Results. A significant decrease of thyroxine (T4) serum levels confirmed hypothyroidism in rats, which received PTU. The MDA level increased and total thiol level decreased in the hypothyroid group compared to control group (p<0.001). Th e activities of SOD and CAT significantly decreased in the hypothyroid rats in comparison to the control. Vitamin E treatment resulted in increased levels of total thiol, SOD, and CAT within aortic and cardiac tissues and decreased levels of MDA in comparison with the hypothyroid group (p<0.01−p<0.001). Conclusions. PTU-induced hypothyroidism resulted in oxidative stress. Chronic administration of vitamin E to hypothyroid rats decreased the oxidative stress markers in the aortic and cardiac tissues.
Sedimentary record of subsidence pulse at the Triassic/Jurassic boundary interval in the Slovenian Basin (eastern Southern Alps)
Authors: Rožič Boštjan , Jurkovšek Tea Kolar , Rožič Petra Žvab , Gale Luka
Published: December 2017

In the Alpine Realm the Early Jurassic is characterized by the disintegration and partial drowning of vast platform areas. In the eastern part of the Southern Alps (present-day NW Slovenia), the Julian Carbonate Platform and the adjacent, E-W extending Slovenian Basin underwent partial disintegration, drowning and deepening from the Pliensbachian on, whereas only nominal environmental changes developed on the large Dinaric (Friuli, Adriatic) Carbonate Platform to the south (structurally part of the Dinarides). These events, however, were preceded by an earlier - and as yet undocumented extensional event - that took place near the Triassic/Jurassic boundary. This paper provides evidence of an accelerated subsidence from four selected areas within the Slovenian Basin, which show a trend of eastwardly-decreasing deformation. In the westernmost (Mrzli vrh) section - the Upper Triassic platform-margin - massive dolomite is overlain by the earliest Jurassic toe-of-slope carbonate resediments and further, by basin-plain micritic limestone. Further east (Perbla and Liščak sections) the Triassic-Jurassic transition interval is marked by an increase in resedimented carbonates. We relate this to the increasing inclination and segmentation of the slope and adjacent basin floor. The easternmost (Mt. Porezen) area shows a rather monotonous, latest Triassic-Early Jurassic basinal sedimentation. However, changes in the thickness of the Hettangian-Pliensbachian Krikov Formation point to a tilting of tectonic blocks within the basin area. Lateral facies changes at the base of the formation indicate that the tilting occurred at and/or shortly after the Triassic/Jurassic boundary
Some perisphinctoid ammonites of the Štramberk Limestone and their dating with associated microfossils (Tithonian to Lower Berriasian, Outer Western Carpathians, Czech Republic)
Authors: Vašíček Zdeněk , Reháková Daniela , Skupien Petr
Published: December 2017

The present contribution deals with the taxonomy of seven species of perisphinctoid ammonite from the Štramberk Limestone (Outer Western Carpathians, Czech Republic) deposited in Moravian-Silesian museums. The age of these studied ammonites is compared with that of index microfossils contained in the matrix adhering to or infilling the studied specimens. The ammonites document a stratigraphic range from earliest Tithonian to early Berriasian. In addition to taxonomy and new ontogenetic data on some species, we also present data on their palaeogeographic distribution. The occurrence of Subboreal himalayitids in the Štramberk Limestone of an early Berriasian age is determined by both the microfauna and accompanying ammonites, which indicate connection of the Silesian-part of the Tethyan Carpathian area with the Subboreal Russian Platform Basin. These records also suggest an early Berriasian age (Jacobi Chron) for the lowermost part of the Ryazanian stage in its type area.
Influence of Total Inertia Effects in a Thrust Curvilinear Bearing Lubricated with Newtonian Lubricants
Authors: Walicka A. , Jurczak P.
Published: December 2017

In the paper, the flow of a Newtonian type of lubricant in the clearance of a curvilinear bearing is considered. It is assumed that the bearing walls are modelled as smooth and impermeable. In analytical considerations, full inertia of the longitudinal flow and partial inertia of the circumferential flow are taken into account. The equation of motion of the lubricant is solved by the modified method of averaged inertia. A thrust bearing and spherical bearing are considered, for which dimensionless pressure distributions and the bearing capacity are given.
The conceptual and semantic shift of “noble” and its synonyms as a case of semiosis
Authors: Komova Tatiana , Sharapkova Anastasia
Published: December 2017

The paper explores the interrelation between the socially biased phenomena, affecting the conceptual domain of “knighthood” in the XIII-XV centuries. Nobility and knighthood as interrelated conceptual entities became increasingly complicated, due to cultural semiosis, which brought about drastic conceptual and semantic changes in the adjectives under scrutiny: worthy, noble, gentle. The analysis of corpus and lexicographic material as well as romances of the period demonstrated that conceptual changes became the major triggers for the large-scale semantic changes within the category.

Published: December 2017

RFID systems work on communication between data carriers and data readers. This basic data transmission is provided in virtual network, which have to be steady. Reading range of data readers is depending on many factors, as devices parameters, surroundings and type of data carrier. Nowadays, technology provides better communication between devices, which dramatically increases distance, in which devices are able to communicate with each other. With proper setting, interaction in logistic processes could be faster and stable. This paper explores equipment needed for transport information from data carrier through data readers to software devices, which are responsible for information processing.
The impact of the level of market competition intensity on enterprises activities in area of intellectual capital
Authors: Prusak Rafał
Published: December 2017

Market activity for today’s enterprises means continuing work to better understand the needs of their customers to provide them higher level of satisfaction. Building market advantages using a traditional approach based on material resources becoming less and less likely to increase competitiveness over the long term. The ability to use intangible assets, often more difficult to identify and manage, is becoming a key issue. Proper management of intangible assets can provide the company with unique market advantages that are unique, durable, and difficult to imitate. This study attempts to characterize selected dependencies between the nature of the actions undertaken by enterprises in relation to intellectual capital in the context of the strength of the level of competition in the market.
Childhood and Children’s Retrospective Media Consumption Experiences
Authors: Korsvold Tora
Published: December 2017

The focus in this article is on childhood and consumer culture with a special view on children’s media experiences retrospective. A historical perspective is applied as history provides an opportunity to reflect on changing processes within contemporary consumer culture, especially with a view on exploring how children grew up within a Norwegian context with the tradition of state regulated media. The following main research question is addressed: What are the dominant narratives on retrospective media experiences (radio and television)? The findings are based on a case study of adults reflecting on media consumption. Their experiences have been collected through focus group interviews as this approach can generate new insights into former experiences and contemporary childhood. The study shows that narratives on childhood in retrospective media experiences are influenced by both contemporary notions of childhood and the new media flow.
Hotels and Halal-oriented Products: What Do Hotel Managers in Slovenia Think?
Authors: Šuligoj Metod , Maruško Helena
Published: December 2017

Background and Purpose:Tourists from the Islamic world are significant stakeholders in the tourism market. The purpose of this paper is to identify the key aspects of halal tourism in connection with the hotel industry. Furthermore, we want to determine whether hotel managers are familiar with halal certification and on what basis they would opt for it.

Design/Methodology/Approach:The research focuses on halal goods, services, and facilities, in general, and specifically in Slovenian hotels; concepts, contemporary trends, and the situation in Slovenia are presented. In response to the literature review, we applied the analysis of the factor loadings to define the important factors that influence the decision-making process; by applying PCA, we reduced the dependent variable to a single factor (although predictions were slightly different).

Findings:The most important elements in the adoption of the certificate are the simplicity and efficiency of the procedure itself and the fact that the process does not require major financial investments. The element that significantly influences the managers’ decision-making process is the possibility of adjusting to the standard of the certificate.

Conclusion:The paper’s main contribution is to deepen the perspective of the development of tourism in an area that remains a relatively undeveloped and unknown niche within the Slovenian tourism/hospitality industry but very promising in the global context.

Published: December 2017

Paz, GA, Iglesias-Soler, E, Willardson, JM, Maia, MdF, and Miranda, H. Postexercise hypotension and heart rate variability responses subsequent to traditional, paired set, and superset resistance training methods. J Strength Cond Res 33(9): 2433–2442, 2019—The purpose of this study was to compare training volume, postexercise hypotension (PEH), and heart rate variability (HRV) responses to different strength training methods. Thirteen trained men volunteered for this study. Three training methods were completed in a randomized design, which included: Traditional Set (TS)—3 successive sets for the lying bench press (LBP), lat pulldown (LPD), incline 45° bench press (BP45), seated close-grip row (SCR), triceps extension (TE), and biceps curl (BC), with a 90-second rest interval between sets and exercises; Paired Set (PS)—3 paired sets for the LBP-LPD, BP45-SCR, and TE-BC, with a 90-second rest interval between sets and exercises; and superset (SS)—3 supersets for the LBP-LPD, BP45-SCR, and TE-BC. During the SS session, no rest was permitted between PSs, followed by 180 seconds of rest after each SS. Ten repetition-maximum (RM) loads were adopted for all exercises. Blood pressure (BP) and HRV were measured at baseline, immediately aftersession, and at 10-minute intervals until 60 minutes after session. Significantly greater training volume was noted under the SS method (8,608.6 ± 2,062.2 kg) vs. the TS method (7,527.5 ± 2,365.1 kg), respectively. Significantly greater training volume was also observed under the PS method (8,262.3 ± 2,491.2 kg) vs. the TS method (p ≤ 0.05). No main effects for HRV and PEH were noted between protocols (p > 0.05). However, similar PEH response intraprotocols were observed for the TS, PS, and SS methods (p ≤ 0.05). Considering the duration of the PEH intraprotocol, large effect sizes were noted for the SS and PS methods vs. the TS method in diastolic and mean BP. Therefore, both the PS and SS methods may be an alternative to the TS method to achieve greater total repetitions and training volume with a tendency toward a longer PEH response.

Giffin, KL, Knight, KB, Bass, MA, and Valliant, MW. Predisposing risk factors and stress fractures in collegiate cross-country runners. J Strength Cond Res 35(1): 227–232, 2021—The purpose of this study was to explore factors associated with increased stress fractures in collegiate cross-country runners. Subjects in this study were 42 male and female cross-country runners at a Division I university. Each athlete completed a questionnaire regarding smoking status, vitamin/mineral intake, previous stress fracture history, birth control usage, menstrual status, and demographic information. Nutritional assessment using a 3-day food record and measurements of whole body, lumbar spine, and hip bone mineral densities (BMDs) were also conducted on each athlete. Results indicated that 40% of the female and 35% of the male runners reported a history of stress fracture, and that all of them did not meet the recommended daily energy intake or adequate intakes for calcium or vitamin D required for their amount of training. Two-tailed t-test found statistically higher incidences of lumbar spine BMD in male and female runners whose daily calcium and vitamin D intakes were below minimum requirements as well as for women whose caloric intake was below the required level. When data on the lumbar spine was evaluated, 31% of subjects (31.8% of the male and 30% of the female runners) were identified as having osteopenia and 4.8% with osteoporosis. Results warrant a need for future longitudinal studies.
Genetics of tumors of the adrenal cortex
Authors: Bonnet-Serrano Fidéline , Bertherat Jérôme
Published: December 2017

This review describes the molecular alterations observed in the various types of tumors of the adrenal cortex, excluding Conn adenomas, especially the alterations identified by genomic approaches these last five years. Two main forms of bilateral adrenocortical tumors can be distinguished according to size and aspect of the nodules: primary pigmented nodular adrenal disease (PPNAD), which can be sporadic or part of Carney complex and primary bilateral macro nodular adrenal hyperplasia (PBMAH). The bilateral nature of the tumors suggests the existence of an underlying genetic predisposition. PPNAD and Carney complex are mainly due to germline-inactivating mutations ofPRKAR1A, coding for a regulatory subunit of PKA, whereas PBMAH genetic seems more complex. However, genome-wide approaches allowed the identification of a new tumor suppressor gene,ARMC5, whose germline alteration could be responsible for at least 25% of PBMAH cases. Unilateral adrenocortical tumors are more frequent, mostly adenomas. The Wnt/beta-catenin pathway can be activated in both benign and malignant tumors byCTNNB1mutations and byZNRF3inactivation in adrenal cancer (ACC). Some other signaling pathways are more specific of the tumor dignity. Thus, somatic mutations of cAMP/PKA pathway genes, mainlyPRKACA, coding for the catalytic alpha-subunit of PKA, are found in cortisol-secreting adenomas, whereasIGF-IIoverexpression and alterations of p53 signaling pathway are observed in ACC. Genome-wide approaches including transcriptome, SNP, methylome and miRome analysis have identified new genetic and epigenetic alterations and the further clustering of ACC in subgroups associated with different prognosis, allowing the development of new prognosis markers.
Collective evaluation in specialised medical consultations
Authors: Galatolo Renata , Cirillo Letizia
Published: December 2017

This article investigates 50 specialised medical consultations conducted by a team of practitioners at a prosthetics centre. Specifically, the article focuses on evaluation sequences in which practitioners collectively assess the conditions of amputee patients by observing changing positions and various portions of their limbs (stumps), in order to choose the best prosthetic device for them. In so doing, practitioners participate in the construction of a shared diagnostic object (the assessable), a process that is crucial in the evaluation sequence and key to understanding the interactional practices whereby the participants transform the patient's limb(s) into a professional case to be processed in the following clinical phases. In particular, what emerges is a shared professional vision upon which all subsequent decision-making rests. This vision is achieved through specific tacit practices reflecting the interplay of various territories of knowledge and building a professional backstage from which the patient is temporarily excluded.
From an Encounter with God to a Life with God
Authors: Poplavsky Roman , Klyueva Vera
Published: December 2017

This article suggests a typology of conversion to Pentecostalism in Russia, based on research among believers in the Russian Khanty-Mansi Autonomous District, Yugra, West Siberia. The typology of religious conversion is based on the analysis of the motives and causes that led the believers to God. The authors identify four types of conversion: socially induced, induced by a religious crisis, induced by a life crisis, and induced by an existential crisis. The socially induced conversion includes a family sub-type, while a rehabilitation sub-type is identified within the conversion induced by a life crisis. The results obtained demonstrate that the reasons for religious conversion in contemporary Russia are, to some extent, rooted in such social problems as addiction to drugs and alcohol, which people seek to abandon in a church. In addition, the authors give a brief overview of the history of the Pentecostal communities in the region under consideration and of their social and demographic characteristics.

Radiolytic Conversion of Platinum, Rhodium, Osmium and Palladium Salts into Metal Coatings and Metal Nanoparticles
Authors: Cele Takalani , Beukes Philip , Beuvier Thomas , Chavez Elvia , Maaza Malik , Gibaud Alain
Published: December 2017

We herein report on the effect of gamma ray radiation on platinum, osmium, rhodium and palladium salt solutions for synthesis of nanoparticles. Pt, Os, Rh and Pd salt solutions were exposed to intense gamma ray irradiation with doses varying from 70 to 120 kGy. The metal ion salt solutions were easily converted into metal nanoparticles using this radiolysis method. The radiolytic conversion effect produced metal nanoparticles suspended in solution. For Pt, Pd and Rh a metal coating on the edges of the polypropylene tube used as a container was unexpectedly observed but not for the Os solution. X-Ray diffraction (XRD) and high resolution transmission electron microscopy (HRTEM) analyses confirmed that both the coating and the metal nanoparticles correspond to the pure metal coming from the reduction of the initial salt. Quantitative analysis of the XRD patterns shows information about the size and stress of the converted metals. The production of a metal coating on polypropylene plastic tubes by gamma ray irradiation presents an interesting alternative to conventional techniques of metal deposition especially for coating the inner part of a tube.
Una propuesta didáctica para la asignatura de Educación Ambiental en la Educación Superior, a partir de ideas preconcebidas sobre “el medio ambiente”
Authors: Dagmara Gomes Ramalho ; Fernanda da Rocha Brando. Giselle Alves Martins ; Marlene Lucia Aguilar Benavides ;
Published: December 2017

En las leyes y documentos oficiales brasileños, se verifica que en términos normativos, los asuntos relacionados con el medio ambiente y la educación ambiental han sido bien establecidos. A partir de una discusión sobre las concepciones o ideas previas de estudiantes de un curso de Ciencias Biológicas de una universidad pública brasileña sobre el término “Medio Ambiente”, se describe una propuesta didáctica para la asignatura de Educación Ambiental en la formación inicial de biólogos. El objetivo de esta propuesta fue el de abarcar los contenidos necesarios para la construcción de un “saber” y un “hacer” más reflexivo sobre las temáticas ambientales y que promuevan la sensibilización y la toma de decisiones por parte de los estudiantes en situaciones en que estos profesionales puedan llegar a ser requeridos
Diferencias trascendentales entre matematización de la física y matematización para la enseñanza de la física
Authors: Vizcaino Arévalo Diego Fabián , Terrazzan Eduardo Adolfo
Published: December 2017

La comprensión y formalización de las leyes de la física ha sido posible gracias a la combinación de diferentes tipos de aportes, dentro de los cuales la matematización de la física ha desempeñado un papel importante, permitiéndole a la física presentar avances importantes en términos de nuevos descubrimientos y en la formalización de teorías altamente predictivas. Esto ha llevado a pensar que utilizar las formas matemáticas adoptadas por la física como parte de su estructura de explicación, justifiquen la enseñanza de la física basada en la matematización. Por tal razón, se hace necesario entender el significado de la matematización no solo en la física, sino también en su enseñanza, reconociendo sus alcances y restricciones. En este trabajo se presenta un estudio acerca de la relación de la explicación y el lenguaje en la matematización de la física, verificando su existencia en tres momentos históricos de la física y comparando con lo obtenido en la literatura acerca del significado de matematización atribuido en la enseñanza de la física. Se encontró que son diferentes las concepciones de matematización para la física y matematización para la enseñanza de la física, y se mencionan algunas de sus implicaciones en el ámbito educativo.
Desarrollo de los conocimientos sobre los estudiantes durante las experiencias en el practicum: el caso de una aspirante a profesora de Física
Authors: Cifuentes Arcila María Cristina , Uribe Gartner Carlos Julio
Published: December 2017

En este artículo se documenta cómo una aspirante a profesora de física desarrollósus conocimientos sobre sus estudiantes durante su primer año de experienciasdocentes pre-profesionales (practicum). Para ello se adoptó una metodologíanarrativa: las historias se utilizaron como un recurso retórico para expresar losconocimientos de la profesora y, simultáneamente, fueron vistas como el fenómenoy el método de la investigación. Se usaron varias fuentes para recolectarla información: grabaciones de audio de las entrevistas y conversaciones, vídeograbaciones de episodios de enseñanza, notas de campo de los investigadoresy documentos escritos por la profesora. El análisis narrativo de la informaciónreveló algunas características de los conocimientos de la profesora sobre susestudiantes, y permitió documentar su desarrollo como un proceso de construcciónde nuevos sentidos en respuesta a situaciones particulares de clase,en tres etapas. En la primera, la profesora empezó a conocer la disposición deánimo, el rendimiento académico y el comportamiento de sus estudiantes. En lasegunda, aprendió algunas estrategias de motivación y formas de interactuar másapropiadas para propiciar los aprendizajes de algunos de ellos, sobre todo dequienes le generaron seguridad cognitiva, emocional y relacional, o inseguridad.En la tercera, pudo conocer algunas de las dificultades de sus estudiantes parael aprendizaje de la física, particularmente para realizar actividades de clasetipicas (resolver problemas estandarizados de lápiz y papel y leer textos científicosescolares) y para comprender algunos conceptos y sistemas conceptuales(como la diferencia entre los significados del lenguaje cotidiano y del lenguajecientífico, o cómo inferir las relaciones significativas entre conceptos). Se analizaronalgunas implicaciones de estos resultados para la formación inicial delprofesorado de física.

Fue necesariocaracterizar la infraestructura tecnológica de las instituciones, describir los usosque le da la comunidad académica a las tic, evaluar sus conocimientos acercade las tic y conocer la gestión que las directivas han hecho de ellas en el currículode las instituciones del municipio. Se utilizó un enfoque mixto, desde el paradigmainterpretativo, a partir de tres categorías de análisis: conocimientos y usos,infraestructura tecnológica y gestión tecnológica; se focalizó la población objetode estudio en los grados 10 y 11 de las instituciones educativas del municipio, apartir de la aplicación de un cuestionario a docentes y estudiantes y entrevistasa directivos, luego de un muestreo aleatorio. Se pudo inferir que los vectorescausa-efecto acerca de las tic, su apropiación y uso no radican exclusivamenteen la existencia de equipos disponibles, ni salas acondicionadas, ni jornadas decapacitación a los docentes; el problema tiene una de sus principales fuentes enla cultura organizacional: los nuevos ambientes de aprendizaje plantean retosa quienes los operan y a su vez exigen nuevas estructuras y herramientas pararesponder a nuevos propósitos y filosofías curriculares.
EDUCACIÓN CIENCIA, TECNOLOGÍA Y SOCIEDAD (CTS) EN AMÉRICA LATINA: UNA PERSPECTIVA HUMANÍSTICA Y EMANCIPADORA
Authors: Martinez Leonardo Fabio
Published: December 2017

Escribir unas palabras con tono académico para un colega y amigo que nos ha dejado un legado significativo, resulta difícil y trae a nuestra memoria recuerdos compartidos sobre la necesaria humanización y transformación de la educación en ciencias. Como todos los intelectuales comprometidos con el movimiento CTS, conocí a Wildson a través de su escrito legendario titulado Educação em Química: compromisso com a cidadania, obra que fue publicada en 1997 y cuyas líneas nos invitan a dialogar sobre la educación CTS en el ámbito internacional y latinoamericano. Después tuve la oportunidad de departir con Wildson en el Encuentro Nacional de Eduación en Química desarrollado en el 2008 en Curitiba, Brasil, y tuve la fortuna de contar con su presencia como parte del jurado de mi tesis de doctorado sustentada en agosto de 2010. Así inicié mi contacto con la vasta y representativa obra de un gran pensador freireano y, en consecuencia, me acerqué a un ser humano sencillo, fraterno y sobre todo comprometido con un proyecto educativo crítico y emancipador.

Published: December 2017

Aborda la relación entre las políticas ambientales y la formación de educadores ambientales en Brasil, a partir del análisis del Programa de Formación de Educadores ambientales (ProFEA), el cual reúne aspectos del Programa Nacional de Educación Ambiental (PNEA). En su metodología como Programa de Formación, ProFEA propone un conjunto de procedimientos denominados “4 Procesos Educacionales”, los cuales son: 1) Formación de Educadores Ambientales; 2) Educomunicación Socioambiental; 3) Educación en la escuela y en otros espacios y estructuras educadoras; 4) Educación en foros y organizaciones. El ProFEA cita a las Salas Verdes como ejemplo de estructuras educadoras, en este sentido, el articulo discute el potencial del Proyecto Sala Verde, del Ministerio de Medio Ambiente (MMA) en la formación de educadores ambientales para así problematizar su relación con los desafíos impuestos; igualmente, el potencial de las Salas Verdes como estructuras educadoras y democratizadoras del acceso a la información socioambiental. En la métodologia fueron utilizados como procedimientos técnicos la investigación bibliográfica y documental. La exploración documental se realizó en dos etapas, primero fue realizado el análisis de documento ProFEA, utilizando la herramienta tecnológica Atlas Ti (programa de computador de investigación cualitativa), con el Analisis Textual Discursiva (ATD) (una perspectiva fenomenológica que utiliza la descripción a partir de interpretar las palabras escritas en los textos y orienta la separación de los textos en unidades de significado, agrupando esas unidades para determinar las categorías iniciales, intermedias y finales), a fin de ampliar el conocimiento sobre las actividades de formación de educadores ambientales en Brasil, propuesta por el ProFEA. En su segunda etapa, la obtención de datos sobre el Proyecto Sala Verde utilizó notas de campo de naturaleza reflexiva, listas de discusiones de las Salas Verdes, publicaciones en la página del Ministerio de Medio Ambiente (MMA) y el blog del proyecto, también el análisis de documentos internos de diagnóstico e informes de gestión del Departamento de EducaciónAmbiental (DEA). La investigación refleja un proceso de generación de conocimiento en el cual lo sociocultural de este conocimiento es representado por una política. Se concluye que tal política puede ser definida por medio de un artefacto cognitivo en Educación Ambiental, una vez que permite conocer las actividades de formación de educadores ambientales de Brasil.
Teoría de la integración conceptual: una mirada desde la interacción con un robot móvil
Authors: Ramírez Cano Oscar Yecid , Ruales Tobón Camilo Fernando
Published: December 2017

En esta investigación se pretende analizar los procesos de significación que sepresentan en la interacción que tienen las personas con los objetos tecnológicos.En este caso se analiza el resultado de la interacción entre un niño y un robotmóvil controlado con un dispositivo que suprime el contacto físico a partir dela implementación de una cámara RGB y un sensor de profundidad, llamadoKinect, diseñado por Microsoft. Este estudio se analiza teniendo como referentela teoría de la integración conceptual planteada por Fauconnier y Turner; lacual busca entender cómo emergen nuevas ideas a partir del reconocimientoy la integración de elementos preexistentes. La anterior teoría nace de los postuladosde Lakoff y Johnson, de sus estudios sobre la construcción de sentidoen la metáfora, para que luego esta sea utilizada en el campo de la semiótica.El presente trabajo es de corte cualitativo e involucró a miembros de unainstitución educativa de la ciudad de Bogotá, quienes interactuaron con unrobot móvil tratando de conducirlo de un lugar a otro, usando como interfazel dispositivo Kinect. Estas experiencias fueron documentadas a través de videosy entrevistas, en las cuales se indagaba sobre la proyección del ejerciciodesde escenas previas y hacia nuevos escenarios. Los análisis realizados a laluz de la teoría de la integración conceptual dieron cuenta de las relacionescognitivas que se presentaban. No obstante las diferencias generacionales delos participantes, se establecen elementos en común, los cuales se observan laformulación y construcción de la red de integración conceptual.Los hallazgos, en general, permiten establecer que en el proceso de significaciónque se presenta al interactuar con un objeto nuevo se requiere de experienciasprevias con objetos ya establecidos y definidos por una cultura. En ese sentido,cobra vigencia el concepto de anclaje material planteado por Hutchins, paraentender lo que sucede a nivel del cambio de frame cultural. Asimismo dichosanclajes materiales, se presume, pueden llegar a convertirse en insumos denuevas redes conceptuales. De acuerdo con esta premisa es posible contemplar  la formulación de nuevas metodologías de aprendizaje que conduzcan a obtener mejores resultadosen el contexto escolar.

Este texto surge de reflexiones críticas sobre acciones e investigaciones relacionadas con la constitución docente y su articulación a prácticas formativas vivenciadas en la formación inicial y continuada de profesores de ciencias. El estudio tiene como objetivo comprender cuestiones referidas al aprendizaje escolar y sus implicaciones en el desarrollo del pensamiento humano, atendiendo al abordaje histórico-cultural referenciada por Vigotsky, Leontiev y Elkonin. El proceso es de carácter cualitativo y se enfoca desde la construcción de sentidos y significados. Se realizan lecturas rigurosas de publicaciones, relatos, disertaciones, tesis, diarios de campo, documentos y otros registros producidos al interior del grupo de investigación durante los últimos 25 años, con el ánimo de generar comprensiones sobre los procesos de constitución docente, mediante relaciones entre la formación inicial y continuada de profesores. El ensayo, expresa la comprensiones sobre el aprendizaje escolar y los diferentes estadios de desarrollo del pensamiento humano, en el trascurso del texto, se describen algunas prácticas formativas desarrolladas junto a profesores en formación inicial y continuada frente a la apropiación de sus conocimientos. Finalmente se desarrollan sugerencias, acerca del trabajo docente y su sentido, advirtiendo que, la ruptura entre significado y sentido, conlleva a la alineación de la labor, comprometiendo o desvirtuando dicha actividad.
La nación, la escuela y “los otros”: reflexiones sobre la historia de la educación en Argentina y Colombia en el imaginario civilizatorio moderno
Authors: Ocoró Loango Anny
Published: December 2017

El presente artículo se centra en la historia de la educación en dos países latinoamericanos: Argentina y Colombia para decodificar cómo, desde sus orígenes como nación, la intención de afianzar la nacionalidad y la ciudadanía se usó para la exclusión, la invisibilización o la integración subordinada de poblaciones y culturas que no eran consideradas parte de la nación. También señala las limitaciones que han tenido los análisis desde el campo de la historia de la educación en América Latina, para dar cuenta y problematizar el correlato racista y excluyente hacia los pueblos indígenas y las comunidades negras y afrodescendientes. Por último, ofrece una lectura sobre las líneas de investigación y aportes que diferentes autores vienen haciendo para analizar esta problemática desde los textos escolares.

Se trata de un estudio de corte cualitativo a partir de la configuración de un trayecto hologramático que permitió trabajar con asociaciones y organizaciones complejas, tanto antagónicas como complementarias sobre el conocimiento de los jóvenes acerca de sus repertorios tecnológicos. Los resultados demuestran que las reflexiones pedagógicas en torno a los ecosistemas comunicativos, requieren propender por la construcción de saberes a través de las prácticas del profesorado, en articulación con los aprendizajes e interacciones comunicativas que los jóvenes emprenden fuera del ámbito escolar, como referente dialógico sobre los entramados de expresión y actuación que se dan a través de nuevos repertorios tecnológicos. En este sentido, se reconoció la necesidad de articular al ámbito escolar lo que acontece al interior de los ecosistemas comunicativos tecnomediados, sin pretensión de intervenirlos o manipularlos, sino más bien, para dinamizar desde ellos, los aprendizajes que dan apertura a nuevos encuentros, diálogos, comunicaciones e interrogantes que requieren de una continua reflexión y transformación en las comunidades educativas.

A SEMANA CULTURAL NO COLÉGIO ESTADUAL GELVIRA CORRÊA PACHECO: UMA POSSIBILIDADE DE EDUCAÇÃO PARA O LAZER
Authors: Gonçalves Felipe , De França Rodrigo , Rechia Simone
Published: December 2017

Com a percepção da necessidade de se criar um ambiente de discussão e reflexão com os alunos, em tornoda temática do espaço escolar e seu entorno, emergiu o seguinte desafio: como a Educação Física Escolarpode contribuir para o fortalecimento da identidade local, sem deixar de lado sua especificidade? Apoiadosna abordagem qualitativa, as etapas de investigação foram: seleção da temática, aplicação de roteirode observação e questionários avaliativos. Este artigo tematiza o projeto da Semana Cultural desenvolvidono Colégio Estadual Gelvira Corrêa Pacheco, em Curitiba/PR. Para concretização da proposta — que tinhacomo temática “O Bairro da nossa Escola” — também foi necessário buscar relações interdisciplinaresdentro do espaço escolar. Nossa preocupação foi trazer algo que pudesse contribuir à formação dos educandose que, de alguma forma, levasse em consideração sua realidade e tivesse relevância para o seudia-a-dia, fomentando uma educação para o lazer, na qual o corpo discente seja instrumentalizado paraassumir o protagonismo das suas escolhas, no seu tempo/espaço destinado às vivências de lazer.
ANTROPOTÉCNICA Y OCIOSIDAD. EJERCITARSE PARA LLEGAR A SER OCIOSO
Authors: Diaz Velasco Andres
Published: December 2017

El propósito central de este escrito es argumentar en favor de las formas de vivir ociosas basadas enejercicios prácticos de ociosidad. Para ello, se contempla en primera instancia la antropología filosóficade Peter Sloterdijk, según la cual el hombre se produce a sí mismo viviendo su vida en distintasformas de ejercicio. En seguida, el texto contrasta esta tesis con los planteamientos de Michel Foucaultrespecto a la vida como obra de arte. Se finaliza estableciendo la tesis de que ser ocioso no significasimplemente no-hacer-nada, en cuanto que se trata de una actitud vital absolutamente virtuosa, generosay creativa que se adquiere conforme a un cuidadoso ejercicio de la libertad y la espontaneidad.
CONCEPCIONES SOBRE CUERPO EN LA FORMACIÓN DE MAESTROS DE EDUCACIÓN FÍSICA DE LA UNIVERSIDAD DE LOS LLANOS
Authors: Campo Polo Fernando
Published: December 2017

El estudio aquí presentado buscó comprender las concepciones de cuerpo que subyacen en la formación de maestros del programa de Licenciatura en Educación Física y Deportes de la Universidad de los Llanos, y cómo estos se develaron en el currículo. Para dicho análisis, se acudió a la aplicación de una metodología que permitiera vislumbrar la tendencia y la agenda investigativa de docentes, para prospectar con objetividad dicha situación. Se debió, entonces, abordar la metodología del rastreo arqueológico a partir de la descripción de las condiciones conceptuales del saber objeto de estudio. Los resultados se antojan inquietantes e interesantes, en tanto revelación documental, partiendo de ciertas categorías de análisis que dan cuenta del trasegar del cuerpo en el currículo a partir de 1998. Finalmente, se destaca el estado de la presente investigación, en tanto resultados parciales, debidos, fundamentalmente, a la revisión archivística y documental que en materia de normas, políticas y directrices institucionales develan prácticas discursivas sobre el cuerpo, lo que posibilita una primera aproximación e interpretación.

A decrease in bone mass is observed in hemophilic patients. The aim of this study was to evaluate bone mineral density (BMD), parathyroid hormone (PTH), 25-hydroxy vitamin D (vitamin D), and a bone formation and resorption marker, procollagen type I N-terminal propeptide (PINP) and urinary N-terminal telopeptide (uNTX) respectively, in hemophilic patients and healthy controls. Laboratory parameters related to the pathogenesis of bone loss such as neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) were also evaluated. Thirty-five men over 18 years of age, with severe hemophilia (A and B) and receiving secondary prophylaxis, were included in the study. The same number of age-, sex-, and ethnicity-matched healthy controls were evaluated. Anthropometric, biochemical, and hormonal parameters were determined in both groups. No significant difference in anthropometric parameters was found between the two groups. The BMD was low in 34% of hemophilic patients. Vitamin D, calcium, and free testosterone levels were significantly lower (p < 0.001, p = 0.011, p < 0.001, respectively), while PTH, PINP, and activated partial thromboplastin time (aPTT) levels were significantly higher (p < 0.014, p = 0.043, p < 0.001, respectively), in hemophilic patients compared to controls. There was no significant difference between the two groups in NLR, PLR, phosphorus, thyroid-stimulating hormone, and uNTX level. The reduction of bone mass in hemophilic patients may be evaluated using the markers of bone formation and resorption, enabling early detection and timely treatment.

Published: December 2017

Background: Maternal sepsis is one of the leading causes of maternal mortality around the world. The aim of this study was to study the prevalence, clinical profile and fetomaternal outcome of maternal sepsis at a dedicated Obstetric critical care unit of a tertiary care centre of North India. It was retrospective study conducted in tertiary care centre in North IndiaMethods: Women diagnosed as sepsis or septic shock at any point in pregnancy and up to 6 weeks postpartum (irrespective of the source of infection) were included in the study. Demographic, clinical, microbiological and outcome data were recorded from the case sheets of all patients admitted in obstetrical critical care unit between January to December 2016. Outcome measures: Prevalence, bacterial organism, source of infection, mode of delivery, period of gestation, maternal and fetal outcome.Results: The prevalence of maternal sepsis was 16.5/10,000 live births. The number of maternal deaths attributable to sepsis were 35, making the maternal mortality ratio due to sepsis 128/100,000 live births. 87% of the cases were unbooked. 22% presented antenatally while 58% were postpartum and 20% were postabortal. Genital tract infection was most common source of infection. E. coli was the predominant organism in 28% followed by Methicillin resistant staphylococcus aureus in 12%. The mortality from sepsis was very high (78%). 54% of cases required mechanical ventilation and around 7% had to be shifted to intensive care unit for advanced life support and care. Sepsis was associated with preterm delivery and a high perinatal mortality rate.Conclusions: Early recognition of the severity of infection and prompt management by a multidisciplinary team of intensivists, anesthetists, neonatologists, obstetrician, midwives are the key to success. Vigilant infection control measures must be strictly practiced during all pregnancy events.

Background: The most common current graft choices in ACL reconstruction are the bone-patellar tendon–bone (BPTB) graft and the quadrupled Hamstring graft. Though BPTB is considered to be the gold standard; hamstring tendon (HT) grafts have increased in popularity over last decade. Our aim in this study is to assess the complications, comorbidities, difficulties and final outcome between BPTB and Hamstring grafts in ACL reconstruction.

Methods: 71 male patients with isolated tear of ACL between age group of 18-45 years were included in the study. 35 patients in group A underwent ACL reconstruction using bone patellar tendon bone autograft and 35 patients in group B were managed by reconstructing ACL using quadrupled Hamstring autograft. All the patients in both the groups were followed up at 08 weeks,06 months and 01 year post surgery and evaluated by Lysholm knee scoring system.

Results: The Lysholm scoring scale scores in anterior cruciate ligament reconstruction showed that BPTB group and Hamstring group have similar outcome. One case (2.8%) each of patellar fracture and graft contamination occurred in BPTB group. There were 09 cases of superficial infection of which 03 were from BPTB group and 06 were from Hamstring group.

Conclusions: There is statistically no significant difference in the overall clinical outcome between bone-patellar tendon- bone and Hamstring autografts. With precise surgical techniques, meticulous attention to sterility and proper wound closure most of the complications in both the techniques can be minimized or avoided.
