Authors: Gribkov A. A. , Brodov A. A. 
Published: May 2019

Optimization of logistics is an important component of the country regions provision by metal products. Data on consumption of ferrous metals finished rolled products and steel pipes in 2016–2017 by RF federal districts quoted, as well as structure of the produced rolled products assortment in 2016 and 2017 in RF as a whole and in the Southern Federal District (SFD). Results of analysis of indices of production rolled products and steel pipes in SFD presented, as well as level of their consumption at the expense of supplies from local sources, other districts of Russia and for export. For the analysis of finished metal products shipment to the domestic market, including the regional one and for export, correspondent calculations were made using database of the Russian railways and the one of Federal Customs, as well as data on purchase of industries-consumers. Further based on the data, the apparent consumption of finished products in the region was determined. In 2017 in the SFD the finished products were produced in the amount of 1.99 mt. The structure of produced finished products in the SFD had a peculiarity – extremely low (1.6%) share of sheet products. Capacity utilization for rolled products and pipes production in the SFD in 2017 was 66.8 and 58.2% correspondently, that gives a chance to steel-works of SFD to increase the production quickly in case of demand increasing. For elimination the mentioned imbalance, it is necessary to balance the assortment of the products being produced and consumed, as well as to develop integration ties between plants of SFD and nearby districts, and undertake measures for encouragement of metalconsuming industries development.

Effective control of thermal state of a blast furnace (BF), considerably depending on the qualification of the technological personal, is an important condition for smelting of hot metal of required composition. Application of computer training systems (CTS) in the process of education of technological personal of BF shops is one of the effective methods of professional knowledge and skill perfection. The CTS, implemented at PAO NLMK, based on a model of thermal state of BF, elaborated in Ural Federal University and supplemented with the models of existing disturbances. Adjusting of dynamic characteristics accomplished on the base of regularity of heat- and mass exchange. According to the tasks of BF heat operative control, during the training at the CTS transient processes are studied through channels of BF thermal state control, skill is mastered to identify the tendencies of BF thermal state change in case of non-controlled disturbances action. Most important stage of the training – implementation of adequate solutions to compensate declination of BF thermal state parameters from the set-up level. The CTS implemented at PAO NLMK is operating in the mode of training and testing. The main parameters of BF operation for every particular scenario are displayed at a mnemonic diagram, which completely corresponds to the mnemonic diagram of particular BF. Within the frame of transient processes dynamics studies, tasks are stipulated to modify a BF thermal state by application of control programs. When a scenario of BF thermal state control in case of non-controlled disturbances action is realized, the process parameters change is imitated at the mnemonic diagram. It will be done in case of one of the following parameters change: coke quality change, reducibility change, iron ore material grain size change, distribution of ore by radius change. The CTS includes a module of administration, which allows collecting the statistics of tasks fulfilment by pupils and estimating the results according to accepted algorithm. The application of CTS enabled to perfect the competence of technological personal, which was expressed by declining of off-grade hot metal share.

The problem of coal-cleaning wastes utilization is actual in many countries of the world. At present in Russia these wastes are used only at 10–15% in different industries, but the potential of their utilization is much wider. Peculiarities of waste-less technology of powdered coal-cleaning wastes gasification in the slag suspended layer considered, resulted in conditional synthesis gas obtaining with simultaneous reducing and isolation of metal from ash and slag. Besides, another result was obtaining a highporous alumina-silicate slag (microspheres), applicable as a light filler for paints and coatings with low heat conductivity, as well as absorbing agent etc. It was shown, that based on the earlier elaborated jet-emulsion facility, a waste-less technology of gasification (processing) of coal and its cleaning wastes can be created resulting in obtaining three liquid products: synthesis gas (or electric power), alumina-silicate micro granules and iron with dissolved in it rare metals. Apart from the wastes of coal-cleaning availability, the presence of powdered iron-containing wastes (dust from gas-cleaning systems, iron ore concentration tails) can increase the efficiency of the technology. The increase will take place due to stable gas-slag emulsion support and the two-phase flow in the connection channels, as well as decrease of gaseous oxygen consumption at the expense of it substitution by oxygen of iron oxides.

LOCALISATION OF IMPACTED MAXILLARY CANINES USING PANORAMIC RADIOGRAPHS; A NOVEL TECHNIQUE THAT USES BICONDYLAR LINE AS REFERENCE
Authors: G.A Dr. Adersh , Salim Dr. Shiad , Nair Dr.Vinod , Sebastian Dr. Aneesh 
Published: May 2019

Purpose: To localize the impacted maxillary canines in the alveolus using panoramic radiographs.
Methods: The present study was a retrospective radiographic chart review of 81 patients with 92 impacted maxillary canines from the Department of oral and maxillofacial surgery, PMS College of Dental Science and Research, Trivandrum. Of the 92 impacted maxillary canines, 57 were impacted buccally and 35 were impacted palatally. The ratio formed between the distance from the crown tips of impacted maxillary canine and ipsilateral central incisors were measured. We used these measurements to predict the position of the tooth and correlate this prediction with the actual approach used during surgery.
Results: The ratio of the canines in the buccal group was 1.35± 0.144(range, 1.04 to 1.88). Palatal group has got little higher values with the mean ratio of 1.93± 0.52 (range, 1.29 to 3.22). The ratios were distributed over a scatter plot (Figure 2). The diagnostic test characteristics for the values greater than 1.45, greater than 1.50 and greater than 1.55 were taken. These values were used for constructing a receiver operating curve. There was a better sensitivity and specificity for the values greater than 1.50(sensitivity: 94.29%, specificity: 91.38%). Logistic regression showed that if the ratio is more than 1.50, there is a chance of 19.3 times to get a canine palatally impacted.
Conclusion: There is significant difference in the vertical position of buccal and palatal canines in the alveolus. Based on our values we found that palatally impacted canines are restricted more superiorly.

PLATELET COUNT INCREASES IN CHRONIC OTITIS MEDIA PATIENTS WITH BLOCKED EUSTACHIAN TUBE
Authors: DIKKER Okan , ALTINDAĞ Cem , YILDIRIM Güven , KUMRAL Tolgar Lütfi 
Published: May 2019

Objectives: The aim of the present study was to examine the levels of complete blood count (CBC) parameters (Neutrophil, lymphocyte, platelets, MPV, NLR, and PLR) in patients with both perforated eardrums and dysfunctional eustachian tubes to determine which of these parameters might be reliable biomarkers of chronic otitis media prior to surgery, as inflammation is significant component of middle ear pathology.
Materials and methods: In this study, we enrolled 95 patients with 18-65 years old. Patients with chronic otitis media (perforated tympanic membranes) more than three months in duration who have no draining ears, were enrolled in Okmeydani Training & Research Hospital. Patients were divided into three groups: Group 1 is “Open eustachian tube” group in which pressure changes (if evident) during swallowing were recorded on stepladder-type graphs; Group 2 is “Blocked” group, who could not neutralize the negative pressure even by repeated swallowing. Group 3 is “Partially blocked” group in whom some residual pressure persisted even after five swallows. The groups were compared in terms of laboratory tests.
Results: There was a statistically significant difference between 3 groups in terms of platelet levels (p>0.05). We found that group 2 / blocked eustachian tube had significantly increased platelet counts values when compared to the group 1 and 3. There was no significant difference among group 1 and group 3. There was no statistically significant difference between the 3 groups in terms of neutrophil, lymphocyte count, MPV, NLR, PLR levels, bone and air hearing thresholds.
Conclusion: We found that the platelet count increased in chronic otitis media patients with blocked eustachian tube. This may be a simple and inexpensive biomarker with acustic impedencemeter tests supporting eustachian dysfunction before tympanoplasties.
Key Words: Hematological biomarkers; eustachian tube dysfunction; chronic otitis media

Published: May 2019

Este artigo tem como objetivo discutir como a pesquisa qualitativa desenvolveu-se e consolidou-se no contexto da educação do Brasil, levando em consideração a cronologia dos mais diversos ciclos históricos que deram sustentação aos fundamentos teóricos-metodológicos da pesquisa em Educação no Brasil. A partir deste trabalho empírico bibliográfico que se fundamentou nas diferentes fontes, as quais abordaram reflexões e problematizações das questões metodológicas, demonstrou-se que o pensamento educacional brasileiro passou por diferentes ciclos na história da educação brasileira, tendo configurações que são historicamente comprovadas nas produções dos trabalhos científicos. Para esta discussão, recorreu-se a autores consagrados no que diz respeito a discussão sobre pesquisa qualitativa no contexto educacional Brasileiro, como por exemplo, Marcos Suel Zanette que resgata os ciclos históricos da pesquisa qualitativa no Brasil, assim como Bernadete Gatti que traz em suas discussões a relevância dos métodos de pesquisa qualitativa em educação. A temáticas de estudo nas pesquisas qualitativas foram ampliadas ao longo do tempo, assim como a abertura e implantação de mestrados e doutorados, que sofreram influências estrangeiras principalmente no tocante a metodologia. Além disso, houve um grande incentivo que proporcionou esta formação no exterior, tendo como consequência a atuação de professores com especialização em trabalhos acadêmicos, ensino e pesquisa.
Mudanças nas práticas de agricultores de cacau orgânico certificado no Sudoeste paraense, Amazônia Oriental
Authors: Cruz Brenda Glaude Arrais , Rocha Carla Giovana Souza 
Published: May 2019

A produção de cacau orgânico certificado requer alterações significativas nas práticas produtivas e comerciais dos agricultores familiares. Este trabalho visa estudar as mudanças nas práticas de famílias de produção do cacau orgânico certificado nos municípios paraenses de Pacajá, Brasil Novo e Medicilândia. Foram entrevistadas quarenta e sete agricultores de três cooperativas de produtos orgânicos. Identificou-se o que tem influenciado nas mudanças das práticas produtivas de agricultores familiares em relação à produção de amêndoa de cacau na região, destacando-se quatro lógicas que impulsionaram tais mudanças: a) ênfase na qualidade do produto, b) qualidade atrelada à garantia de retorno financeiro, c) irregularidade nas práticas para produção de amêndoa de boa qualidade, e d) pouco influenciada pelos estímulos do mercado. As diferenças entre as lógicas estão associadas ao tipo de produção da amêndoa, com qualidade (Acoaq) e convencional (ACC) e a forma como cada agricultor adotou as mudanças em seus sistemas. As mudanças dos sistemas decorrentes das práticas adotadas e da comercialização seguem mais a perspectiva da agricultura orgânica, e foi verificado que alguns sistemas são poucos influenciados pelas lógicas externas após a entrada nas cooperativas. As principais razões são a falta de mão de obra e de capital de giro nas cooperativas para o pagamento imediato.
What is biographical research and why is this method important in teachers’ and professors’ formation?
Authors: Kich Bruna Viedo , Martins Adriana Claudia 
Published: May 2019

Despite of emergence on the 70’s on the education field and being consolidate around a decade later, the biographical research is still poorly understood by some researchers and not fully accepted by some members of the scientific academy. The explanation most discussed by theorists is related to the positivist perspective that persists even on human sciences. Considering this, the purpose of this article is to elucidate what are the bases of a biographical research from an introductory perspective and why is it important in teacher’s and professor’s formations, presenting suggestion to further studies and interventions on this area. In order to carry out this study, prominent authors on the fields of biographical research and teacher’s formations were highlight and brought to a discussion summarizing their main ideas. This study is justified by the belief that this research may help educators and researchers with their practices in any area of the education field by introducing them this methodology. As results, the article highlights the importance of biographical research on the process of pursing the self-awareness when teaching.
O conto africano a dona do fogo e da água e as suas dimensões estéticas: estudos, reflexões e experiências numa classe de alfabetização
Authors: Alves Ana Carolina Almeida , Lima Valéria da Silva 
Published: May 2019

Este artigo tem como objetivo apresentar o conto africano A Dona do Fogo e da Água, uma obra literária do autor Celso Sisto (2012) e ilustrações de Rubem Filho, como elemento oriundo da cultura africana. A pesquisa realizada foi bibliográfica fundamentada nas dimensões estéticas que analisa os elementos ilustrativos e o texto narrativo, sob o aspecto étnico-cultural do Continente africano, utilizando-se das estratégias de leitura preconizadas por Celso Sisto (2012), Ana Aparecida Arguelho de Souza (2010) e José Auri Cunha (2005). A pesquisa participante foi desenvolvida com uma atividade interativa de mediação de leitura numa classe de alfabetização no município de Volta Redonda. Destacamos a importância da interação dialógica entre os sujeitos participantes perante a relevância cultural, predominantemente enraizada na origem da civilização brasileira, tal como, a tradição dos contos populares e a preservação da memória folclórica pelos contadores de história, transmitida de geração a outra, além de apresentar as belezas e riquezas do misticismo por meio de imagens ilustrativas, que por meio do imagético e da narrativa textual, tem a finalidade de expressar durante a prática dialógica, o pensamento reflexivo das dimensões estéticas do conto africano para compreender o contexto histórico e étnico-cultural africano e afro-brasileiro, valorizando-o como produtor de cultura.
A negação da identidade do trabalho como princípio educativo: um olhar profundo sobre o sentido histórico do trabalho diante da política do capital
Authors: Rosa Alcemir Horácio , Aquino Francisco José Alves de 
Published: May 2019

O trabalho é algo inerente ao homem, e, historicamente, fundamental para o desenvolvimento e para a sobrevivência humana. Sobretudo; além da sobrevivência, o trabalho é algo naturalmente produtor e agregador de conhecimento e de saber. E é neste sentido que o trabalho ganhou uma identidade educativa. No entanto, essa identidade educativa do trabalho está sendo reestruturada diante das mudanças advindas das inovações tecnológicas, globalização, internacionalização do capital e de como a sociedade vem se construindo e se modificando para atender as exigências de crescimento do capitalismo. A presente pesquisa tem como objetivo desencadear uma compreensão e revelar como o capitalismo vem se reestruturando e causando intensas modificações na estrutura do trabalho, sobretudo, em sua essência e sua identidade educativa. Este estudo desenvolveu-se através de levantamento bibliográfico, constituído em caráter qualitativo, através da bibliografia de alguns autores importantes para a temática como Saviani (2007), Engels (2013), Taddei (2014) e Antunes (2007). Conclui-se que o trabalho vem adquirindo uma identidade cada vez mais alienada; adquirindo um sentido reducionista e pobre que se resume em forma de emprego, de funções e exercícios profissionais. Passo a passo o trabalho vem perdendo seu sentido e identidade. E assim causando uma verdadeira negação do trabalho enquanto atividade criativa e inerente ao ser.
