Bio-Inspired Strategies against Diabetes and Associated Complications: A Review
Authors: Choudhary Shalki , Kalra Vinni , Kumar Manoj , Tiwary Ashok Kumar , Sood Jatin , Silakari Om
Published: December 2019

Bio-molecules are the most important target to be considered while designing any drug delivery
system. The logic lies in using such bio-sensing or bio-mimicking systems in their formulations
that can mimic the active site of those receptors to which the drug is going to bind. Polymers mimicking
the active site of target enzymes are regarded as bio-inspired polymers and can be used to ameliorate
many diseased conditions. Nowadays, this strategy is also being adopted against diabetes and its
complications. Under hyperglycemic conditions, many pathways get activated which are responsible
for the progression of diabetes-associated secondary complications viz. retinopathy, neuropathy, and
nephropathy. The enzymes involved in the progression of these complications can be mimicked for
their effective management. For an instance, Aldose Reductase (ALR2), a rate-limiting enzyme of the
polyol pathway (downstream pathway) which gets over-activated under hyperglycemic condition is
reported to be mimicked by using polymers which are having same functionalities in their structure.
This review aims at critically appraising reports in which target mimicking bio-inspired formulations
have been envisaged against diabetes and its complications. The information summarized in this review
will provide an idea about the bio-sensing approaches utilized to manage blood glucose level and
the utility of bio-inspired polymers for the management of diabetic complications (DC). Such type of
information may be beneficial to pharmaceutical companies and academia for better development of
targeted drug delivery systems with sustained-release property against these diseased conditions.
Spatial filtering of signals with spectrum overlapping
Authors: Shevchenko M. E. , Gorovoy A. V. , Solovyov S. N.
Published: December 2019

The paper considers the spatial filtering methods of signals with spectrum overlapping under conditions of a priori uncertainty of the directions of arrival from radio sources. The estimates of the directions of signals arrival obtained by ESPRIT or MUSIC are used in order to build a spatial filter. It is shown that when using ESPRIT, unlike MUSIC, an additional calculations of filter coefficients based on estimates of the directions of signals arrival are not required, and the quadrature components of the signals are formed simultaneously with estimates of the direction of their arrival. The probability of error performances of minimum shift keying signals which were divided by spatial filtering on the basis of ESPRIT and MUSIC using seven-element circular and angular antenna arrays are given.

Authors: Goluschko D. A. , Zatylkin A. V.
Published: December 2019

An analysis is made of the methods for organizing automated workstations of control vehicles from the complex of automated control tools with serial and parallel switching on of control panels of intelligence tools. Structural models of the reliability of workstations have been compiled. The results of the reliability calculation showed that with parallel connection, reliability increases by 1.79 times. It was revealed that for the practical implementation of parallel connection of control panels, it is necessary to improve the algorithm of their work. The improvement consists in the implementation in the control panel of the newly introduced function of restricting access for operators of automated workstations to reconnaissance equipment of control machines. The proposed access control algorithm is developed with full preservation of the functionality of existing control panels.

Authors: Shim Sangyong , Lee Hyunjoo , Lee Kisung , Lee Yoonsun , Park Jonghyun , Jang Hyunsook
Published: December 2019

Purpose: As the number of cochlear implant (CI) students has steadily increased in Korea, the number of CI students enrolled in inclusive classrooms has also risen. The present study aimed to investigate speech perception abilities at the sentence and connected speech levels of the CI students in inclusive classroom settings and to analyze the effects of chronological age, age at CI implantation, and wearing period of CI on speech perception.Methods: A total of 63 students were recruited from elementary (30 students) and secondary (33 students) schools. The speech perception were assessed by three sub-tests from the Korea National Institute for Special Education-Developmental Assessment of Speech Perception: Sentence Recognition Test (SRT), Sentence Comprehension Test (SCT), and Connected Speech Test (CST).Results: The results showed that there was no significant difference between SRT and SCT, but performances in CST were significantly poorer than those in sentence-level tests for both CI student groups. Also, both elementary and secondary school CI students showed, individually, a wide range of differences in performance across all tests. In SRT, SCT, and CST, 30-53% of the elementary and 23-39% of the secondary CI students did not reach the norm (-2 standard deviation) ranges, when compared to their normal peers. Multiple regression analysis indicated that the effects of three variables on speech perception were not significant.Conclusion: The findings of this study suggest that the CI students in the inclusive classroom need individualized rehabilitative and educational supports.

“NÃO SOMOS OBJETOS DE PESQUISA”: EM BUSCA DE UMA ANTROPOLOGIA EM COLABORAÇÃO
Authors: Machado Tadeu Lopes
Published: December 2019

Este artigo busca desenvolver uma reflexão crítica a respeito da forma com que a antropologia desenvolve seu conhecimento e estabelece sua base metodológica, mas também busca apontar alguns mecanismos para superar o modelo metodológico que herdamos da tradição antropológica. Portanto, é travado um diálogo com estratégias etnográficas que se colocam como vozes dissonantes da concepção metodológica e epistemológica convencionais. Ao longo do trabalho será feita a descrição de uma experiência pessoal observada recentemente com os povos indígenas de Oiapoque (AP), que, durante um movimento de reivindicação por melhorias e oferta de vagas específicas e entrada diferenciada no vestibular da Universidade Federal do Amapá (UNIFAP), apontaram a necessidade de romper com o olhar colonizador dos pesquisadores brancos, que segundo os indígenas “veem esses grupos étnicos ainda como simples objetos de suas pesquisas”. Ao final apontamos a necessidade de construção de uma pesquisa antropológica em colaboração, intersubjetiva e voltada para atender aos anseios dos povos com os quais executamos nosso trabalho.

Sangihe Islands belong to a complex tectonic area at the subduction of the Eurasian plate and the Philippine Sea. Sangihe subduction zones are complex subduction zone, so that there is a need for continuous movement monitoring. Previous research had been carried out to monitor movement of the Sangihe subduction zone, but no monitoring has been done in 2019. Therefore, this study aims to monitor movement of Sangihe subduction zones with the latest observation data.This study aims to obtain velocity of Sangihe Islands plate movement during 2017 to 2019. Observation was performed using 3 monitoring control points for 7 days in 2019. While observation data from 2017 to 2018 were obtained from previous studies. Observations was carried out using GNSS differential method technology. Loosely constrained of weighted parameter was performed in least square adjustment of GNSS data daily processing, while Kalman Filtering algorithm applied for combining multiyear GNSS data to estimate the velocity refer to ITRF 2014 using GAMIT/GLOBK.This study indicates that Sangihe Islands has horizontal movement to the Southeast with velocity vector of 1 to 2.16 cm/year. This results confirm the previous studies in that area.
Calculation Of Sedimentation Rate at Sempor Reservoirs in 2018 Using Modified Universal Soil Loss Equation Method (MUSLE)
Authors: Arini Septi , Yulaikhah Yulaikhah , Cahyono Bambang Kun
Published: December 2019

Sempor Reservoir located in the Telomoyo River Basin in the Serayu River region is categorized as one of the priority watersheds based on the 2015-2019 Strategic Plan of the Ministry of Environment and Forestry. Priority watershed is a watershed that gets more attention in controlling water pollution, one of which is sedimentation. Watershed observation and management activities are needed for the reservoir to operate optimally. One of the observations and management activities of the Sempor Watershed is the calculation of sedimentation rate. In this research the sedimentation rate was calculated using the MUSLE method that included runoff parameter, erodibility, slope, land cover and conservation factor. The Sempor watershed boundary is obtained through delineation of DEM. The calculation is done by utilizing a Geographic Information System (GIS) through analysis of soil type maps, length and slope maps,  land cover and conservation maps with the boundaries of the Sempor Reservoir. Based on this result, the Sempor Reservoir has a sedimentation rate of 166,173,500 tons/year and a sedimentation thickness rate of 3,7259 mm/year. According to the provisions of the Ministry of Forestry in 2009, the rate of sedimentation thickness in the Sempor Reservoir is included in the medium class. The river as one of the potential means of sediment transport contributes to the rate of sediment thickness of 3.7256 mm /year, while for areas outside the river coverage it only 0.003 mm/year. The river has a major influence on sedimentation in the Sempor Reservoir.

Authors: Samokhvalov Mikhail A. , Gejdt Andrej V. , Paronko Aleksandr A.
Published: December 2019

Introduction. The paper examines the main types of anchor piles used in geotechnical construction are examined in terms of their design variants, the scope of their application, advantages and disadvantages, designs and types of drill bits depending on the type of soil foundation. The aim of the study is the search for and analysis of existing domestic and foreign designs of drill-and-injection anchor piles used for strengthening existing foundations and bases, for dowel reinforcing landslide slopes and different installations such as caissons, retaining walls, masts, towers and pillars bearing pull out loads as well as discovering new, previously little-known anchor designs. The objectives of the study are to perform a patent search and a literary review of existing designs of drill-and-injection anchor piles.

Materials and methods. Systematization, structural, comparative and contrastive analyses. The paper also utilized the theoretical generalization of the data obtained in the detailed analysis of literature and patent data containing information about the previously developed and applied designs of anchor piles were used in the search and selection of relevant literature.

Results. The application of the anchor piles is of great importance in modern foreign and domestic geotechnical practice. The need for their application is connected with ensuring the safety of construction, reducing the period of foundation work execution, and the economic efficiency of approved engineering solutions.

Conclusions. It was found that despite a large number of anchor pile types, all of them, as a rule, are made the using technology of the company Bauer. It is revealed that commonly the anchor design consists of three main parts: a head (supporting element), a rod (element transferring the load from the anchor head to its root) and an anchor root (element transferring the load from reinforced structure to ground and foundation soil).
Quantity assessment method for the sustainability of a construction company
Authors: Abramov Ivan L.
Published: December 2019

Introduction. Professional construction customers (investors) often face the problem of selecting a reliable contractor, when they have to assess construction companies for potential involvement in their projects guided, among other things, by a directly non-measurable emergent indicator of sustainability (from now on referred to as sustainability of a construction company). The given problem is of particular concern as most construction companies are now financially unstable.

Materials and methods. The article defines the sustainability of a construction company. It also evaluates the sustainability of a construction company indicator by a number of statistical estimate iterations. The study proposes an evaluation method for quantitative integrated synthetic aggregators of sustainability of a construction company and identifies several private indicators Xj characterizing a construction company’s stable condition.

Results. The advantages of the proposed evaluation method for the sustainability of a construction company are as follows: a unified information basis (construction operations indicators) for the assessment of qualitative and quantitative integrated synthetic aggregators of sustainability. This method is based on unified evaluation indicators of construction operations: technical, technological, organizational, and economical. The proposed method has an advantage of the versatility of the resultant own and comparative assessments of the sustainability of construction companies, visual clarity of obtained results, and relative ease of calculation procedures.

Conclusions. This study illustrates a procedure developed for evaluating quantitative indicators of the sustainability of a construction company. This procedure offers a high level of accuracy in determining the reasons contributing to the lower sustainability of a construction company and identifying symptoms indicative of loss of sustainability. An integral indicator is formed that assesses the stability of the construction company according to the results of statistical analysis and represents a weighted sum of the values of the initial indicators of construction operations and activities of the enterprise. In this way, businesses can assess both their own condition and the condition of proposed contractors.
Organizational support of BIM-technologies

Published: December 2019

Introduction. Building information modeling (BIM) is a modern approach to design and construction management. It can improve the efficiency of the construction production and quality of design documentation and accelerate business process flow. The paper discusses the problems of organizational supporting information transfer from one automated workplace to another down the technological chain of design and construction.

Materials and methods. When creating a full line of software applications by the same developer, high speed and completeness of information transfer are ensured. In contrast, a universal data presentation is developed, that allows using different software at different stages. Many software manufacturers support the IFC-format (Industry Foundation Classes).

Results. One of the life cycle support tasks is to obtain a scope worklist. Implementation of drawings using BIM-technology requires the internal discipline of designers and the significant preparatory work of the entire design company. The paper shows that the completeness of data transfer from one software to another using a universal format is not guaranteed. The detected problems confirm the need to create a universal classifier of building elements and construction activities. The suggested universal facet-hierarchical classifier contains five levels. However, it can be supplemented with technologies and a list of applied resources.

Conclusions. One of the main prerequisites for the introduction of the BIM-technologies is a correct organization of design and construction activities. It is necessary to develop the classifications of project elements, to prepare drawing file templates, to create instructions for employees, to conduct personnel training, and to determine the data transfer routes. The project must be provided with allocated funds for technology preparation.
The question of animal technical capacities
Authors: Cuevas Badallo Ana
Published: December 2019

The ability to use and make technical artifacts has been considered exclusive to human beings. However, recent findings in ethology in light of observations made in nature and in laboratory show the opposite. In the area of philosophy of technology there are few exceptions that take into account the ability of some non-human animals to manufacture and use tools. In this paper I want to show some reasons to reconsider other possibilities. It seems that capacities such as intentionality, culture or even the complexity of the structures of manufactured object are not exclusive to human beings. I will suggest a different way of analyzing objects created by non-human animals, one that tries to explain the gradualness of the structure, but also the plasticity of the behavior exhibited by non-human animals. These two elements (structure and behavioral plasticity) allow a deeper understanding of the great variety of objects that other animals also manufacture and use.
La evolución de la biología y la biología evolucionista: especie y finalidad
Authors: Labrador-Montero Daniel
Published: December 2019

Are species real categories or just conventions? Are species natural kinds? Are teleological statements a distinctive feature of biology? Can life sciences escape from teleology? These are common issues in philosophy of biology. This paper aims to show that in order to answer to each of these questions it is inevitable to take a position respecting the others. Therefore, there is a historical relation between the concept of species and teleological issues. In order to analyse such relation, I will take a historical perspective.After making such historical reconstruction focused on the Aristotle, Linnaeus, Buffon and Lamarck thoughts, I will analyse the Darwinian peculiar view respect teleology and his ideas about species. Although Darwin set out the collapse of teleological essentialisms in biology, there are important vestiges of teleology in his theory.
Completud débil y Post completud en la escuela de Hilbert
Authors: Aranda Víctor
Published: December 2019

The aim of this paper is to clarify why propositional logic is Post complete and its weak completeness was almost unnoticed by Hilbert and Bernays, while first-order logic is Post incomplete and its weak completeness was seen as an open problem by Hilbert and Ackermman. Thus, I will compare propositional and first-order logic in the Prinzipien der Mathematik, Bernays’s second Habilitationsschrift and the Grundzüge der Theoretischen Logik. The so called “arithmetical interpretation”, the conjunctive and disjunctive normal forms and the soundness of the propositional rules of inference deserve special emphasis.

Introduction: Caregiving of the palliative patient is a stressful
and challenging condition, affecting the caregiver’s physical, emotional,
psychological, and social well-being. This study aimed to determine depression,
anxiety, and stress levels of the caregivers of palliative care patients.Methods: This cross-sectional study was conducted with
caregivers (n=234) in a palliative care unit of a hospital in Balıkesir and
Edirne between April 2018 and January 2019. The data were collected by a
socio-demographic questionnaire and the Depression Anxiety Stress Scale (DASS).Results: Severe and extremely severe depression was detected in
20.1% of the caregivers of palliative patients. Anxiety and
stress were found in 32% and 12.4% of the respondents, respectively. The DASS score was higher in participants who had a chronic disease or were living with the
patients.

Conclusions: Providing psychosocial support
to caregivers of palliative patients may improve the quality of life of both
the patients and the caregivers. Necessary interventions are recommended not
only to the patients but also to the caregivers.

EspañolEl ambiente familiar se considera uno de los contextos más importantes en la vida de las personas. El presente estudio centró su interés en el bienestar personal que este ambiente sociofísico genera en sus habitantes. El objetivo general fue identificar la relación que existe entre el ambiente familiar positivo (AFP) y el bienestar personal en individuos que viven en zona urbana y rural. La muestra estuvo conformada por 202 personas, de las cuales 68% eran de sexo femenino y 32% del masculino. Las edades oscilaron entre 18 y 76 años con una media de 34.7 (DE = 14.3). Se utilizó un instrumento para medir factores del ambiente sociofísico de las familias y el bienestar personal. Se llevó a cabo el análisis de confiabilidad, estadísticos descriptivos y comparativos, así como un modelo de ecuaciones estructurales. Los resultados comprueban que existen diferencias en algunas dimensiones sociofísicas del ambiente familiar entre las personas que habitan en zona urbana y aquellos que residen en área rural. Además, se probó que el factor de orden superior denominado ambiente familiar positivo se encuentra significativamente relacionado con el bienestar de los individuos.EnglishFamily environment is considered one of the essential contexts in life; one of the reasons is because people spend most of their quality time in the home. This study focused its interest in the positivity that this socio-physical context generates in the individual. The study aimed at identifying the relationship between the construct called a positive family environment and the personal well-being of people living in urban and rural contexts. A sample of 202 people gave their answers, 68% woman, and 32% man, the age was between 18 y 76 years old with a mean of 34.7 (SD = 14.3). The instrument combined scales to measure socio-physical components in the family environment and personal well-being. Reliability, descriptive, and comparative analyses, as well as a structural equation model were performed. Results showed the existence of differences between people living in urban and rural zones on most of the socio physical dimensions of the family environment. A higher-order factor was formed with physical and social aspects, this variable is called a positive family environment, and it is significantly related to personal well-being.
AS RADIAÇÕES NA MEDICINA: O QUE DIZEM LIVROS DIDÁTICOS DE FÍSICA DO ENSINO MÉDIO?
Authors: Coelho da Silva André
Published: December 2019

Tomando os livros didáticos como suporte privilegiado dos conteúdos educativos, objetivamos compreender de que forma livros didáticos de Física abordam a temática da utilização das radiações na Medicina. Fundamentados em noções de Análise de Discurso, analisamos se e como nove coleções aprovadas pelo PNLD-2018 o fazem em termos: da extensão e dos momentos dedicados ao assunto; da acurácia e do detalhamento conceitual; e das visões sobre as inter-relações entre Ciência, Tecnologia e Sociedade. Em média, cada coleção dedicou menos de duas páginas ao assunto, especialmente nos livros destinados ao 3º ano e em capítulos sobre ondas eletromagnéticas e Física Moderna. Os tópicos mais abordados foram radiografia, radioterapia e Medicina Nuclear. Encontramos imprecisões que acabam dificultando ou até mesmo interditando a possibilidade de produção de sentidos pertinentes do ponto de vista científico em onze trechos. Consideramos também que 28 trechos poderiam ter sido melhor detalhados com o objetivo de possibilitar menor abrangência no espectro de sentidos possíveis e, consequentemente, maior esclarecimento aos leitores. De forma geral, os trechos consultados evidenciam uma visão pouco crítica sobre as inter-relações entre Ciência, Tecnologia e Sociedade, predominando o entendimento da Física como maior promotora do progresso. Por fim, tendo em vista os resultados obtidos, sugerimos tópicos cuja presença nos livros didáticos poderia contribuir junto à formação de cidadãos conscientes e críticos sobre aspectos e problemas contemporâneos.
O CLUBE DE CIÊNCIAS COMO PRÁTICA EDUCATIVA NA ESCOLA: UMA REVISÃO SISTEMÁTICA ACERCA DE SUA IDENTIDADE EDUCADORA
Authors: Schmitz Vanderlei , Tomio Daniela
Published: December 2019

No Brasil existem escolas com Clubes de Ciências em funcionamento e uma significativa produção científica acerca dessas práticas educativas para o ensino de Ciências. Diante disso, desenvolvemos uma pesquisa de revisão sistemática com o objetivo de enunciar uma identidade educadora para os Clubes de Ciências a partir da análise de conceitos e objetivos dessa prática educativa na escola, disseminados na produção científica brasileira. Para isso, foi elaborado um protocolo de revisão sistemática para leitura das pesquisas, inventariadas em cinco portais de produção científica. Os conceitos e objetivos para Clubes de Ciências identificados nas 60 pesquisas brasileiras foram organizados em categorias de análise e interpretados com base em Bernard Charlot, na perspectiva teórica das relações com o saber. A partir da síntese da revisão sistemática, podemos concluir, na busca de uma identidade educadora, que um Clube de Ciências caracteriza-se em um meio de relações com o saber, em que seus participantes, estudantes e professores, compartilham experiências das três figuras do aprender: a epistêmica, a social e a de identidade, mobilizados pelo trabalho intelectual, na direção da formação humana. Diante disso, evidenciamos as possibilidades e perspectivas que os Clubes de Ciências têm para o ensino de Ciências nas escolas.
UM ESTUDO DE OBSERVAÇÃO E “ESCUTA” EM ESCOLAS DO ENSINO FUNDAMENTAL PÚBLICAS: A “ARTE DE FAZER” A AVALIAÇÃO DA APRENDIZAGEM DE PROFESSORAS DE CIÊNCIAS NATURAIS
Authors: Dantas Cláudio Rejane da Silva , Massoni Neusa Teresinha
Published: December 2019

Este artigo busca apresentar parte dos resultados de uma pesquisa mais ampla que investigou o processo de avaliação da aprendizagem, centrando no componente curricular Física no âmbito da disciplina de Ciências, anos finais do Ensino Fundamental, em escolas públicas do Município de Porto Alegre, RS, coordenadas pela Secretaria Municipal de Educação. Adotamos a abordagem da pesquisa qualitativa e o estudo de caso na acepção de Stake (2011). Realizamos estudos distintos envolvendo, ao todo, dez escolas públicas. Este texto focaliza resultados de observação e escuta das práticas cotidianas escolares através da promoção da escuta de longos diálogos em diferentes momentos, e imersão na sala de aula junto a três professoras de Ciências para compreender os “modos de fazer” a avaliação dessas professoras (três estudos de casos, um em cada escola), bem como captar o significado da avaliação na perspectiva de estudantes. A partir da análise da legislação brasileira e de uma revisão da literatura e de posturas teóricas surgiu a necessidade de buscarmos compreender as artes de fazer a avaliação da aprendizagem, as fabricações e “invenções anônimas” de professoras de Ciências, aqui reveladas como táticas de resistências na perspectiva da teoria das práticas e invenções cotidianas de Certeau (2014). Evidenciamos que as professoras fazem uso de estratégias e táticas em um processo criativo de subversão das normas que lhes são impostas para avaliar, como forma de resistência. Os três estudos mostram a riqueza de dar a palavra e a necessidade de proceder à escuta de professores, que é, ao mesmo tempo, uma escuta externa e uma escuta de si para compreender seus modos de fazer a avaliação, suas “bricolagens” para enfrentamento de problemas de várias ordens (violência, infrequência, ausência de sonhos e expectativas nos estudantes, desvalorização profissional, políticas desencontradas, salários defasados, etc.). A escuta da palavra parece auxiliar na reinvenção de suas histórias, como professoras, diminuir a angústia frente às pressões e revela também demandas da escola à academia. Os estudantes dizem que o professor deveria ouvi-los mais e não avaliar apenas o quanto eles dominam o conteúdo. Desta forma, observação e escuta do cotidiano escolar pode estar se revelando um passo inicial indispensável para a construção de políticas públicas e melhorias do processo avaliativo.

A todo o momento, outras formas de se fazer e pensar o ensino batem às portas das escolas e convidam para repensar a relação desta com a comunidade. Os espaços não formais de educação, cada vez mais, vêm constituindo um campo de investigação na área do ensino de ciências. Os Museus de Ciências tornam-se espaços atrativos para o público em geral e em especial ao escolar, onde professores buscam outras maneiras de ensinar e de potencializar a aprendizagem na educação básica. Nesta perspectiva, o objetivo deste trabalho foi o de analisar como ocorre o ensino de ciências no Centro de Ciências e Planetário do Estado do Pará (CCPP). O trabalho tem uma abordagem de cunho qualitativo, utilizando como estratégia o estudo de caso (único e holístico), e para a descrição e análise dos dados utilizou-se a Análise Textual Discursiva (ATD). Os sujeitos da pesquisa são graduandos de licenciatura (biologia, física e química) que atuam como monitores no CCPP. A partir dos dados obtidos observa-se que a divisão entre ensino de ciências formal/não formal/ informal é uma linha tênue, permeável, que permite que características transpassem as definições herméticas da literatura da área. Constatou-se que ocorrem diversas características formais/informais no ensino de ciências não formal. O ensino de ciências híbrido aflora na pesquisa como possibilidade de mistura de espaços, de públicos, metodologias e objetivos. Considera-se com a discussão que o campo do ensino de ciências não formal vem se constituindo como área de investigação expoente e de encontro inevitável para as escolas, universidades e para a sociedade como um todo.
ROTAS DE TRANSIÇÃO MODAL E O ENSINO DE REPRESENTAÇÕES ENVOLVIDAS NO MODELO CINÉTICO MOLECULAR
Authors: Quadros Ana Luiza de , Giordan Marcelo
Published: December 2019

Neste trabalho, nos baseamos em estudos envolvendo múltiplas representações e representações multimodais e investigamos aulas sobre o modelo cinético molecular, a partir de episódios de interação entre uma professora de Química e seus estudantes de Ensino Médio, os quais foram registrados em vídeo e analisados por meio de técnicas de análise microgenética. Nas aulas, os estudantes foram convidados a propor representações para três fenômenos observados por meio de experimentos. A professora conduziu as aulas seguintes em torno da avaliação, negociação e aperfeiçoamento das representações. Percebemos, ao longo da atividade, que a comunicação teve caráter multimodal e a professora representou o mesmo fenômeno por meio da fala, desenho, gestos e aparatos experimentais. A análise da performance e da interação multimodal nos permitiu caracterizar rotas de transição entre os modos semióticos. Essas transições se mostraram importantes para a construção de significados, proporcionando algumas restrições produtivas. A performance da professora possibilitou perceber potencialidades e limitações envolvidas no uso da comunicação multimodal e das múltiplas representações.
Institutional change and the paradox of (restitution and) restauration of the institution
Authors: Bojanic Petar
Published: December 2019

My intention in this text is to present the most significant contribution of
some French philosophers and anthropologists to the notion of reconstruction
and advancement of institutions. The paradox of change, reform or
transformation of the institution - is an entirely new institution possible?
How do institutions die? - lies in the difficulty or even impossibility to
change something that manifests what we are as a group. If institutions
really present or represent the relations among all of us, how can they be
changed in the first place? Whence the capacity for change? What allows for
the idea of the ?new??
Engagement and political institutions: the case of ombudsman
Authors: Glusac Luka
Published: December 2019

In this article, I examine the relationship between engagement and political
institutions by using the example of the creation and development of the
ombudsman institution. The article starts with the short introduction to key
theoretical views about institutions, political institutions and
institutionalization. Then, I concentrate on how political institutions
change, i.e. whether they can be changed through social engagement and
whether and when we can actually say that they are originally created by an
engagement. By using the case of ombudsman, I explore if political
institutions can engage themselves and under what conditions, that is,
whether are institutions characterized by in-built permanent reflexivity
possible.
Ethical and ontological dimension of Kierkegaard’s perception of freedom
Authors: Tepic Jugoslav
Published: December 2019

Starting with the point of freedom being one of unavoidable ideas of
existential philosophy, as well as philosophy in general, we shall consider
ethical and ontological aspects of contemplation of freedom in Kierkegaard?s
philosophy. We deem that existential philosophy, ?contemplated? in all its
variations, represents the very horizon or manner of philosophical
comprehension of freedom phenomena, where freedom is integrally observed,
thus allowing us to talk about unique bliss of ontological and ethical
dimension, both of those appearing to be equally important. Therefore,
freedom dominates the Kierkegaard?s determination of individual,
co-determines all its leap stages but also continually makes possible the
sense of human existence.

Enterobacter sp. 3TP2A isolated from a petroleum station was found to produce a novel, highly inducible mesophilic intracellular ?-galactosidase in the presence of lactose up to 76.5 U mg-1. The enzyme was purified to 17.3- -fold after gel permeation chromatography with a yield of approximately 11 %. The optimum pH and temperature values of the purified enzyme were found to be 8.0?9.0 and 35 ?C, respectively. The molecular weight of the enzyme was approx. 60 kDa with a single band by both SDS-PAGE and native-PAGE, and estimated by gel filtration chromatography. The enzyme was inhibited by Zn2+ and EDTA, while Cu2+ had strong inhibitory effect even at low concentrations. Activation by Mg2+ and inhibition by EDTA show that the enzyme is metal- -dependent or a metalloenzyme. The enzyme was slightly activated by 2-mercaptoethanol, while slightly inhibited by iodoacetamide. On the other hand, PCMB inhibited the enzymatic activity to a great extent, whereas it was completely inhibited by N-ethylmaleimide. The Vmax and Km values were calculated as 0.701 ?mol min-1 and 0.104 mM, respectively. The results indicated that the ?-galactosidase Enterobacter sp. 3TP2A might well be a good candidate for use in biotechnology, particularly in the area of environment and health.
Properties of the excited electronic states of guanine quartet complexes with alkali metal cations

Published: December 2019

G-quartets are supra-molecular structures that consist of four guanine molecules connected by eight hydrogen bonds. They are additionally stabilized by metal cations. In this contribution, the excited states of G-quartet and its complexes with lithium, sodium and potassium were studied by employing time-dependent density functional theory. The findings indicate that vertical excitations from the optimized ground state involve transitions from several bases, whereas excitations from the optimized lowest excited state include transitions from one base. The charge-transfer character of these states was analyzed. It was shown that the cations are able to modify positions of the maxima of the fluorescence spectra of the complexes.

Published: December 2019

Introduction. Secretory breast carcinoma is rare subtype of breast carcinoma which occurs primarily in children and young adults, so in the past it was called juvenile carcinoma. Case report. A 67-year-old female patient presented with mass of the right breast since one month. After physical, routine laboratory examination and mammography, core needle biopsy was performed and histopathological examination confirmed invasive carcinoma. Immunohistochemically, estrogen-receptors (ER) and progesteron-receptors (PR) showed weak positive reaction in 10% of tumor cells, while human epidermal growth factor receptor-2 (HER-2) was without expression. After an adequate preoperative preparation, operation was done ? quadrantectomy with sentinel lymph node biopsy. Postoperatively, the patient was treated with 6 cycles of cyclophosphamide, methotrexate and fluorouracil (CMF) combination, radiotherapy (60 Gy) and tamoxifen. After 5-year follow-up the patient had no signs of the disease. Conclusion. Secretory breast cancer is a rare subtype of invasive breast carcinoma with wide age range of occurrence and good prognosis despite its triplenegative immunophenotype. Although the therapeutic management is non-consensual for this breast cancer special type, surgery is considered the mainstay of the treatment as well as the adjuvant chemotherapy and radiation.

Background/Aim. Radiology is a crucial part of dentists? everyday practice. It plays a vital role in diagnosis, treatment planning and the follow-up care of patients. The aim of this study was to evaluate the knowledge of dentists in Serbia concerning the use of radiology in pediatric dentistry. Methods. In total, 252 dentists from across Serbia participated in the study. A questionnaire was created in order to examine dentists? knowledge about the use of radiology in pediatric dentistry. The questionnaire consisted of 39 questions. All questions were analyzed in SPSS 24 statistical software. Results. According to the results, 42.1% of dentists worked in private practice, 17.8% at University clinics and 40.1% in National Health Services. Out of total 252 respondents, only 82 (32.5%) had an x-ray unit. A total of 199 (79%) dentists replied they would diagnose early caries lesions only by inspection, but 30 (11.9%) dentists said they would make a diagnosis by doing both the inspection and taking a radiograph. The results show that 187 (74.2%) respondents said that they did not make an OPG for every patient. When asked about the disposal of radiological waste, 84.3% of dentists did not answer the question. Conclusion. Attempts should be made in order to upgrade and update Serbian dentists overall knowledge about the use of radiology in pediatric dentistry.
