Authors: Bristott Maria Isabel , Kripka Rosana Maria Luvezute , Bedin Silvio Antônio 
Published: January 2019

O presente artigo visa socializar uma proposta de curso de formação continuada de professores e funcionários estaduais, do RS, com o foco na questão do cuidar-se para poder cuidar. Criado a partir de necessidades indicadas pelos próprios professores, buscou promover reflexões por meio de aportes teóricos e metodológicos, de modo a sensibilizar os participantes sobre a importância do cuidado na educação. Constatou-se que os professores estão acostumados a cuidar mais dos outros do que de si e diante das propostas puderam refletir sobre essa questão. Perceberam a importância de rever seus modos de vida e a necessidade de mudanças, que devem iniciar no próprio agir, em relação ao cuidado consigo e aos outros, para que seja possível a construção da cultura do Bem Viver no convívio escolar.

Authors: Lehmann Lucia De Mello e Souza , Ribeiro Claudiane Figueiredo 
Published: January 2019

O registro da presença de alunos com Altas Habilidades ou Superdotação (AH ou SD) tem ocorrido timidamente no ensino técnico e profissionalizante, pela dificuldade de compreender o conceito e seus indicadores. Este trabalho buscou identificar, analisar e sistematizar aspectos indicativos de superdotação em carreiras técnicas. O campo da pesquisa situou-se em escolas técnicas e a população alvo foi o professor. O trabalho seguiu as concepções de AH ou SD da legislação Brasileira de Educação Especial, com o conceito de inteligência e potencialidades. A metodologia utilizada foi a qualiquantitativa, pesquisa-ação. Os resultados apontaram para indicadores que facilitam a identificação de características presentes nos alunos com habilidades acima da média nesta modalidade de ensino.
REFLEXÕES SOBRE O COTIDIANO E A ÉTICA PROFISSIONAL NO SERVIÇO SOCIAL
Authors: Goes Alberta Emilia Dolores de 
Published: January 2019

O presente artigo tem como objetivo problematizar e refletir o cotidiano a partir da atuação profissional em uma perspectiva ética no serviço social. Para o seu desenvolvimento, nos embasamos na literatura, principalmente, nos autores: José Paulo Neto, Myrian V. Baptista, Maria Lucia Barroco, Agnes Heller, dentre outros. Em uma conjuntura de barbárie social como a atual, o cotidiano além de trivial e rotineiro, deve ser visto como um espaço de reflexão e de oportunidades para o desenvolvimento de ações, estudos e pesquisas comprometidas com os usuários. Assim, assumir uma postura crítica frente a realidade social, que se materialize a partir de ações alinhadas com o Código de Ética profissional e o nosso projeto ético-político é ao mesmo tempo nosso desafio e meta.
Cytotoxicity of bracket identification dyes
Authors: Celebi Fatih , Altun Ahmet , Bicakci Ali Altug 
Published: January 2019

ABSTRACT

Objectives:
To investigate the potential cytotoxicity of the bracket identification dyes commonly used in orthodontic fixed appliances.

Materials and Methods:
Six bracket brands representing the market in various aspects were selected. Ten sets of each bracket brand were acquired, and the identification dyes on them were scraped. They were tested for cytotoxicity at three different levels of concentration (2.5 mg/mL, 5 mg/mL, and 10 mg/mL), with the aid of a real-time cell analysis system. The results were compared within and between the groups. One-way analysis of variance and Tukey's post hoc test were used for statistical analysis.

Results:
None of the six investigated dyes displayed cytotoxicity at the 2.5 mg/mL concentration. Of the investigated brands, three at 5 mg/mL and four at 10 mg/mL displayed cytotoxicity.

Conclusions:
Some of the identification dyes in this study did display cytotoxicity at the higher concentrations tested. Alternative methods for bracket identification should be considered.
Realidad de las estructuras organizacionales en el sector público Ecuatoriano 2007-2016
Authors: Mantilla Fuentes Andres Mauricio , Rojas Farez Maritza De Los Angeles 
Published: January 2019

El objetivo de este trabajo es evaluar la aplicación metodológica de la Organización y Administración por Procesos y su incidencia en la planificación del talento humano en el sector público ecuatoriano, en base al marco normativo vigente en el período de análisis.
De los seis ministerios coordinadores existentes hasta abril del 2017, se seleccionó para el estudio el Ministerio Coordinador de Desarrollo Social, con sus ministerios adscritos, y se analizó la información publicada en la página web de cada institución, de obligado cumplimiento por la Ley Orgánica de Transparencia y Acceso a la Información Pública.
Se evidenció que estas instituciones han observado parcialmente tanto la Norma Técnica de Administración de Procesos, como la del Subsistema de Planificación de Recursos Humanos, dejando abierta la posibilidad de crear nuevos productos o servicios, lo que implica formular nuevos procesos que “justifiquen” la demanda del número de servidores, especialmente en los macroprocesos adjetivos que gestionan procesos administrativos, en detrimento de los macroprocesos agregadores de valor, relacionados con la misión institucional. De esta manera, se provoca un desequilibrio en la asignación de servidores, con un exceso de personal en los macroprocesos adjetivos y/o insuficiente personal en los agregadores de valor y gobernantes, con el consiguiente impacto presupuestario.
Circunstancia contra vocación: El diálogo de Gaos con Ortega

Published: January 2019

RESUMENMás allá de la posible influencia de Ortega sobre Gaos, me propongo explorar los radicales filosóficos que convergen en la obra de ambos filósofos en torno a dos de los conceptos que resultaron centrales para sus respectivas filosofías de la vida humana como sujeto histórico: circunstancia y vocación. No los entendieron de la misma forma. De ahí mi propósito de elaborar una comparación entre el rendimiento de ambos conceptos en sus respectivos discursos buscando las iluminaciones que las diferencias arrojan sobre sus respectivas obras.

Abstract
OBJECTIVE To compare effects of tiletamine-zolazepam, alfaxalone, ketamine-diazepam, and propofol for anesthetic induction on cardiorespiratory and acid-base variables before and during isoflurane-maintained anesthesia in healthy dogs.
ANIMALS 6 dogs.
PROCEDURES Dogs were anesthetized with sevoflurane and instrumented. After dogs recovered from anesthesia, baseline values for cardiorespiratory variables and cardiac output were determined, and arterial and mixed-venous blood samples were obtained. Tiletamine-zolazepam (5 mg/kg), alfaxalone (4 mg/kg), propofol (6 mg/kg), or ketamine-diazepam (7 and 0.3 mg/kg) was administered IV in 25% increments to enable intubation. After induction (M0) and at 10, 20, 40, and 60 minutes of a light anesthetic plane maintained with isoflurane, measurements and sample collections were repeated. Cardiorespiratory and acid-base variables were compared with a repeated-measures ANOVA and post hoc t test and between time points with a pairwise Tukey test.
RESULTS Mean ± SD intubation doses were 3.8 ± 0.8 mg/kg for tiletamine-zolazepam, 2.8 ± 0.3 mg/kg for alfaxalone, 6.1 ± 0.9 mg/kg and 0.26 ± 0.04 mg/kg for ketamine-diazepam, and 5.4 ± 1.1 mg/kg for propofol. Anesthetic depth was similar among regimens. At M0, heart rate increased by 94.9%, 74.7%, and 54.3% for tiletamine-zolazepam, ketamine-diazepam, and alfaxalone, respectively. Tiletamine-zolazepam caused higher oxygen delivery than propofol. Postinduction apnea occurred in 3 dogs when receiving alfaxalone. Acid-base variables remained within reference limits.
CONCLUSIONS AND CLINICAL RELEVANCE In healthy dogs in which a light plane of anesthesia was maintained with isoflurane, cardiovascular and metabolic effects after induction with tiletamine-zolazepam were comparable to those after induction with alfaxalone and ketamine-diazepam.

Abstract
OBJECTIVE To determine the relationship between acute volume overload and echocardiographic indices of right ventricular (RV) function and dyssynchrony in healthy dogs.
ANIMALS 7 healthy Beagles.
PROCEDURES Right heart catheterization and echocardiography were performed in 7 healthy anesthetized Beagles at baseline and after induction of volume overload. Volume overload was induced by IV infusion of lactated Ringer solution (150 mL/kg/h for 90 minutes). Echocardiographic indices of RV function, including peak velocity of systolic tricuspid annular motion, tricuspid annulus plane systolic excursion, fractional area change, RV Tei index, RV longitudinal strain (RVLS), and systolic RV longitudinal strain rate (RVLSR), were obtained by use of speckle tracking echocardiography (STE). In addition, SD of the systolic shortening time of the right ventricle for the 6 segments (RV-SD6) was determined with STE.
RESULTS Volume overload significantly increased the RV end-diastolic pressure, compared with the baseline value. Echocardiographic indices of RV function, except for septal RVLSR, were significantly enhanced by volume overload. In contrast, RV-SD6 did not change with volume overload. Although echocardiographic indices of RV function, except for septal RVLSR, were correlated with RV end-diastolic pressure, RV-SD6 was not correlated.
CONCLUSIONS AND CLINICAL RELEVANCE Echocardiographic indices of RV function, including RVLS and RVLSR, were affected by acute short-term volume overload. Therefore, results for assessment of RV function by use of STE in dogs with clinical conditions associated with right-sided chronic volume overload, such as tricuspid and pulmonic regurgitation, should be interpreted with caution.
Charred conifer remains from the Late Oligocene – Early Miocene of Northern Hesse (Germany)
Authors: Uhl Dieter , Jasper André 
Published: January 2019

AbstractFire is an important constituent of many modern and fossil ecosystems. During the last decades a large number of studies have dealt with fires in pre-Cenozoic ecosystems. Evidence for the occurrence of Palaeogene and Neogene wildfires (e.g. in the form of pyrogenic inertinites in lignite deposits) is geographically and stratigraphically widespread. However, as compared to earlier periods (i.e. the Permian and Cretaceous), fewer studies have focussed so far on plants burnt (or charred) in wildfires from these periods, even though these periods are of considerable interest for our understanding of the evolution of modern ecosystems. Here we report the occurrence of charred wood remains belonging to different conifer taxa from the base seam of the former Frielendorf opencast lignite mine in Northern Hesse (Germany). These findings are evidence that these conifers, and the types of vegetation they were growing in, were affected by wildfires occurring during the Late Oligocene – Early Miocene in this region.
The Study of Movement of the Wide Span Tractor-Based Field Machine Unit with Power Method of its Control

Published: January 2019

Abstract
Recently, rapid development of controlled traffic farming convincingly demonstrates the broad prospects of using the wide span tractor-based field machines throughout the world. The issue at hand lies in the fact that having a wide span tractor-based machine with steering-wheel system moving along the tracks of a constant technological track is not a rational option. According to the concept of bridge and rutting agriculture, it is advisable to subordinate the automated means of mechanization to the principles of the functioning of the coordinate transport system in which machines can move only in two mutually perpendicular directions and for implementation of which the field must have strictly defined dimensions. Therefore, a method of power steering similar to a crawler tractor (track-type tractor) can be more efficient in the automatic driving of bridge means of mechanization within the coordinate-transport system than a kinematic control. Furthermore, methodology utilized for selection of design schemes, parameters and operating modes of machine-tractor aggregates can not be used for study of dynamics of the wide span tractor-based field machine. Theoretical study is based on theoretical mechanics, theory of mobile energy facilities, statistical dynamics and theory of automatic control of linear dynamical systems with reproduction of statistically random control and disturbing input effects. Purpose of the research lies in development of a dynamic model of plane parallel motion in the horizontal plane of a wide span tractor-based field machine unit using a power (onboard) method of control, which would allow investigation of impacts of the control parameters and disturbing influences on the controllability and stability of its motion. Mathematical models have been developed and new regularities of the straightforward parallel movement of the wide span tractor-based field machine unit for controlled traffic farming have been obtained. The results obtained allow the validation of new schemes, design parameters and modes of operation with acceptable controllability and stability of movement in the horizontal plane with a power control method of the chassis.

Production of prebiotics via reactions involving lactose as well as malic acid and citric acid
Authors: Csapó J. , Kiss D. , Albert Cs. 
Published: January 2019

Abstract
Prebiotics are such indigestible food ingredients that enter the colon and serve as nutrient for bifidobacteria and lactobacilli. Since fibres and oligosaccharides are the typical prebiotics, we produced prebiotics in our experiments with the reaction of lactose and malic acid as well as citric acid, where these reactions made use of an appropriate concentration of these substances, had an adequate duration, and were carried out under optimal temperature conditions. We determined the optimal parameters of the reaction, measured the loss of the starting materials as well as the increase in concentration of the end-product, and analysed the total sugar content of the hydrolysed prebiotics after hydrolysis by hydrochloric acid. In vitro experiments were performed to demonstrate our end-product’s resistance to carbohydrate-degrading enzymes, which is a fundamental requirement for a prebiotic so that upon reaching the colon it can serve as nutrient for the probiotic bacteria found there.

Published: January 2019

Abstract
In the present paper we propose two mathematical models describing, respectively at the microscopic level and at the mesoscopic level, a system of interacting tumor cells and cells of the immune system. The microscopic model is in terms of a Markov chain defined by the generator, the mesoscopic model is developed in the framework of the kinetic theory of active particles. The main result is to prove the transition from the microscopic to mesoscopic level of description.
A particle model reproducing the effect of a conflicting flight information on the honeybee swarm guidance
Authors: Bernardi Sara , Colombi Annachiara 
Published: January 2019

Abstract
The honeybee swarming process is steered by few scout individuals, which are the unique informed on the location of the target destination. Theoretical and experimental results suggest that bee coordinated flight arises from visual signals. However, how the information is passed within the population is still debated. Moreover, it has been observed that honeybees are highly sensitive to conflicting directional information. In fact, swarms exposed to fast-moving bees headed in the wrong direction show clear signs of disrupted guidance. In this respect, we here present a discrete mathematical model to investigate different hypotheses on the behaviour both of informed and uninformed bees. In this perspective, numerical realizations, specifically designed to mimic selected experiments, reveal that only one combination of the considered assumptions is able to reproduce the empirical outcomes, resulting thereby the most reliable mechanism underlying the swarm dynamics according to the proposed approach. Specifically, this study suggests that (i) leaders indicate the right flight direction by repeatedly streaking at high speed pointing towards the target and then slowly coming back to the trailing edge of the bee cloud; and (ii) uninformed bees, in turn, gather the route information by adapting their movement to all the bees sufficiently close to their position.
Efficiency of regional innovation policy tools: Support of innovative business in the South Moravian Region
Authors: Kostić Miroslav 
Published: January 2019

Abstract
During 15 years of implementation of the Regional Innovation Strategy of South Moravia, the support of innovative business evolved into a set of interconnected programmes for startups and innovative companies with a potential of growth and foreign expansion. Programmes of the South Moravian Innovation Centre (JIC) facilitate creation and development of technology oriented companies in the region, highly concentrated in prioritised high-tech branches corresponding with specialisation of the regional economy (IT, mechanical engineering etc.). Growth of highly qualified jobs (mainly in R&D) in these companies contributes to the increasing orientation of the region on knowledge intensive branches of economy. Emerging companies supported by the JIC show in average a longer lifespan and growth dynamics than comparable newly established companies in the region without this support. Realisation of the programmes also significantly contributes to building of high quality business environment in the region. Problematic aspects of support to innovative business in the South Moravian Region are linked mainly with poor network of investors able to stimulate faster growth of startups, with low motivation of university students to start their own business or with emerging dichotomy in the support of knowledge intensive businesses concentrated in Brno and insufficiently supported businesses with lower knowledge intensity, also operating in priority branches of the regional economy.
Efficiency of regional innovation policy tools: Support to incoming talents and specialists in the South Moravian Region
Authors: Kostić Miroslav 
Published: January 2019

Abstract
Highly qualified and creative people are the key prerequisite of innovation development of every region. Orientation at the development of talents and inflow of qualified people from abroad gained importance during 15 years of implementation of the South Moravian Regional Innovation Strategy. Through the Internationalisation programme, realised since 2006, the regional authority awards scholarships to students from non-EU countries studying at universities in Brno. A substantial part of supported students remains in the region after graduation, working at highly qualified positions. The SoMoPro programme – a unique support tool from Czech but also from European perspective – contributes to the increase of internationalisation and quality of research conducted in South Moravia. Recognised foreign researchers are motivated to move to Brno especially thanks to the newly built top quality research infrastructure. However, turning their short to mid-term stays into a long-term residence is rather difficult given not sufficiently motivating wages in public R&D in Czechia. The needs of increasing number of foreign researchers and other specialists mainly in private sector are addressed by the Brno Expat Centre. In the last years, the number of clients and consultations provided by the organisation grew continuously. Despite more significant impact of national and international mobility schemes and other influences, the aggregate effect of regional activities supporting inflow and maintaining of foreign talents and specialists leads to the increasing attractiveness of the region and the development of a competitive advantage above the other regions of Czechia. Thus the described regional activities contribute to high shares of foreign students and researchers in the region, placing South Moravia on leading positions among Czech regions.
