Ser professor em tempos de cultura digital: marcas de permanência e indícios de mudança
Authors: Santos Luciana Silva dos 
Published: October 2019

Este artigo tem origem na pesquisa realizada no âmbito de Mestrado em Educação, concluída no início de 2013. Teve como objetivo central identificar e discutir elementos do imaginário tecnológico partilhado por professores, tendo em vista analisar como este atravessa as práticas pedagógicas e as relações que os docentes estabelecem com os alunos, no contexto da cultura digital. A partir desse escopo mais geral e tendo por base as teorias da cultura digital e do mito da digitalização, pretendeu-se abordar a percepção que professores têm da atividade docente diante das supostas mudanças pelas quais vem passando a profissão, em tempos de massificação do acesso às tecnologias digitais. A pesquisa, de caráter qualitativo, teve por base a realização de entrevistas individuais semiestruturadas, seguindo a lógica do sistema de rede para a seleção dos entrevistados. Para tanto, foram entrevistados quinze professores de Ensino Médio atuantes, em sua maioria, em escolas estaduais de formação docente, situadas na cidade do Estado do Rio de Janeiro. Os resultados indicam que o imaginário tecnológico vivenciado por estes profissionais apresenta aspectos do mito da cultura digital, no interior do qual prevalece a impressão de que há um maior afastamento entre gerações e a concepção de que os jovens são experts no uso de tecnologias, frente a adultos pouco qualificados nesse âmbito Palavras-chave: Professores. Cultura digital. Funções docentes. Mediação pedagógica.

Published: October 2019

The results of investigations on studying of the impact of agromeasures at the functioning of microbial communities in chernozem typical has been shown. The aim of article was a comparative analysis of the functioning of bacterial and fungal microbiota in sugar beet rhizosphere at the application of biological and intensive (industrial) agrarian systems during culture ontogenesis. We applied a microbial (identification of microorganism’s number and their qualitative composition), ecological (ecological index calculation), biochemical (estimation of the microbial biomass and metabolic coefficient) and statistical (establishing the results probability) research methods is to achieve of this purpose.
The application of agromeasures are significant impact on microbial communities in chernozem typical in sugar beet rhizosphere during ontogeny and are caused the change of trophic relationships and different direction of microbial processes in soil has been established. The phase of plant development is also had a significant impact on the activity of soil microorganisms functioning. The number of root exudates is increased and plant debrises are accumulated in the soil during sugar beet ontogeny. It is promotes to the growth of numbers, biomass and diversity of microbial communities’ in chernozem typical and consequently intensification of soil organic matter transformation. Thus the application of biological agrarian system compared to intensive is helped to optimization of soil microbial complex. It is accompanied the increasing of the number, diversity and content of microbial biomass and growth of microbial groups resistance. This helps to enhance of microbial transformation of organic matter and improve of soil trophic metabolic profile. The use of intensive agrarian system are involved the reducing of the number, diversity and biomass of microorganisms, that accompanied by a simplification of trophic relationships and deregulation of plant-microbe systems.

Authors: Podpryatov G.I. , Davydenko A.Yu. 
Published: October 2019

Today in the world there are many varieties of potatoes which differ as the duration of the growing season and other characteristics. Thus, in the State Register of plant varieties suitable for distribution in Ukraine in 2016 were registered 150 varieties of potatoes, which belong to five groups of ripeness. There is a close link between period of the growing season, weather conditions potato cultivation and accumulation of reserve substances, harvest, struc­ ture of harvest, marketability [1, 2]. Therefore, the aim of our research was to determine the influence of meteoro­ logical conditions, groups of ripeness on formation economic characteristics of potato tubers.
In our studies used potato tubers which apply to two groups of ripeness: medium-early (Satina (standard), Red Lady and Mozart) and medium-ripe (Arosa (standard), Sifra). Potatoes were grown during 2012-2014 years in conditions of “Bioteh Ltd” (Kiev region Boryspil district Gorodyshche village), which is in a zone Forest Steppe of Ukraine.
Weather conditions in vegetation periods 2013 and 2014 compared with 2012 were the better that promoted ob­ tain higher harvest of potato tubers. On the average during three years of studies high harvest observed in the group of medium-ripe (41.1 t/ha) as opposed to 33.5 t/ha in the medium-early group.
The analysis of potato harvest showed that the most suitable for processing French Fries are varieties Satin which dominated tubers with coarse fraction (over 55 grams) – 50.4 % from total weight and partially – Arosa (30.7% in this fraction). Other varieties had the largest part in the fraction 45-55 grams (Red Lady – 57.2%; Mozart – 42.8%, Arosa – 41.5%; Sifra – 41.6%) and are therefore suitable for processing into Chips.
Research marketability of harvest showed that the best result for this indicator in both groups of ripeness ob­ tained in control variants: 75.2-75.3% in the medium-early and 77.9 % in the medium-ripe.

The results of the study of the regularities of the transformation of peat soils (Fibric Histosols Dystric) of Western Polissia of Ukraine are presented. The regional character of the development of peat soils are illustrated by the Kopaivska drainage system (the village of Pishcha, Shatskyi district, Volyn oblast). The criteria for assessing the agroecological sustainability of peatlands subjected to degradation are proposed. Indicators rang together with scoring system are suggested. Route field expeditions were conducted during 2012-2015.
The specific features of changes in agroecological and agrochemical indicators of degraded peat soils are established. The following parametres were investigated bogging, state of the soil surface and cover crop, erosional feature, skeleton soil profile, gritty consistency, number of stumps and wood, depth of humus-accumulated horizons, organic carbon content, mineral nitrogen, labile phosphorus and potassium compounds, radionuclide contamination, ignition loss, soil reaction.
The change of the main diagnostic signs of the agroecological state of degraded peat soils is revealed. The results indicate a change in the degree of degradation from moderate to severe. According to the results of observations, during the years under investigation, there have been significant changes in agrochemical parameters of fire-induced soil. This is due to the variability of meteorological conditions. In particular, there was an increase in the content of organic carbon and mineral nitrogen compounds, in the content of mobile potassium compounds, an increase in the acidity of the soil and radionuclide contamination. Based on the results obtained, measures are proposed to restore the processes of peat formation, their water regimes, and the elimination of fire-induced occurrence. We propose to carry out renaturation and creation of a raw material zone for the production of alternative fuel and energy resources and solid types of fertilizers.

Productivity of sugar beets depending on the method of main soil tillage and levels of fertilization
Authors: Tyrus M. L. 
Published: October 2019

Soil tillage and fertilization level are important in the system of agro-technical measures that increase soil fertility and sugar beets productivity. Today the cultivation of this crop requires a great deal of expense, therefore, there is a need for a wider study of the use of cheap soil cultivation, soil protection, energy-saving soil tillage technologies and appropriate ferti-lization levels.
Under western Forest-Steppe of Ukraine conditions, investigations were conducted on dark grey podzolic light loamy soils where the influence of tillage models and fertilization levels on the formation of sugar beets root crops was studied.
Shallow no-plow tillage of the soil on 14-16 cm is expedient to use as a main tillage under sugar beets. Under favorable weather and climatic conditions, it can provide yielding capacity at the level of deep fall plowing. The use of shallow no-plow tillage helped to increase the yielding capacity of sugar beet roots relative to plowing by 28-30 cm for 1.3 t / ha and the biological sugar output – for 0.2 t / ha. Then the sugar content was by 0.1% higher in the application of deep fall plowing on 28-30 cm.
The optimization of the system of sugar beets fertilization allows ensuring the growth of the yielding capacity of root crops. It is established that the application of fertilizer norm N300P225K350 provides the yielding capacity at the level of 90 t / ha. The sugar content of root crops at the given fertilizer rate was the lowest in the experiment - 16.5 – 16.6%. Thanks to the high yielding capacity of root crops in terms of N300P225K350, the sugar harvesting was the highest and depending on the method of basic soil tillage was 14.95 – 14.79 t / ha. That is in 3.2 times more as to the control, in 1.3 times more than the norm of N180P135K210 and in 1.1 more than the fertilization level N240P180K280.

The most favourable weather and climatic conditions for the production of potato tubers were for the Divo 2011 variety with a yield of 45.9 t/ha and 2013 – 45.1 t/ha. For the Legenda variety 2016, the yield of potato tubers is 40.6 t/ha and 2017 – 43.2 t/ha. Malin White 2013 is 41.4 t/ha and 2017 42.1 t/ha. The average varieties of potatoes showed a slightly lower yield on average over the years of research. However, among the varieties is allocated Nadiyna – 40.3 t/ha, Slovyanka – 37.2 t/ ha and Vera 33.8 t/ha. Among the years, the most high-yielding for the Vera variety was 2016 with a yield of 36.6 t/ha and 2017 year – 37.8 t/ha. Varieties Slovyanka and Nadiyna 2011 and 2012 with yields of 42.6 and 44.3 t/ha and 46.5 and 45.3 t/ha, respectively. Characterizing the yield of potato tubers of medium-late varieties over the years of research, there was a decrease in this indicator compared with medium-early and middle-aged varieties. However, the high yield of the varieties of Dar is allocated – 40.0 t/ha, Alladin – 33.6 t/ha and Oxamit 31.3 t/ha. Among the years, the most favourable ones were: for Oxamit and Alladin – 2011 – 33.5 and 36.5 t/ha, and 2017 – 34.1 and 36.4 t/ha, respectively. Favourable years for harvesting varieties were 2011 and 2012 with yields of 45.7 and 45.8 t/ha.
Thus, the highest yield of potato tubers on average over the years of studies of medium-early varieties of 41.2-43.3 t / ha were provided by weather conditions of 2011 and 2017 years, medium-ripe varieties 41.0-41.1 - 2012 and 2011, medium- late 37,6-38,5 t / ha - 2012 and 2011, respectively.

لا يخفى ما لعلمائنا العرب من جهد كبير في تدوين هذه اللُّغة (اللُّغة العربية) والحفاظ على أصالة هويتها. وهم في جهدهم هذا دونوا كلّ ما سُمِع من العرب وقعَّدوا على غرار ذلك الجمع قواعدهم النَّحوية مراعين في عملهم هذا ما ورثوه من العرب من شعر ونثر؛ إذ كانا أساس عملهما، ولم يكن القرآن الكريم ببعيد عن هذا الجهد الجليل، ولكن الذي يؤخذ على ذلك العمل إبعادهم لكثير من الاستعمال اللُّغويّ عن القاعدة الأساس التي توضع للباب النَّحويّ، وإذا ما عرض هذا الاستعمال على تلك القاعدة اضطرب الأمر وراحوا يضعون قواعد فرعية مبنية على التَّـأويل والتَّـقدير لتستقيم عندهم القاعدة الفرعية مع القاعد الأصل.
وفي الحقيقة إنَّ في كثرة القواعد النَّحويَّة إرباكاً وإشغالاً للنحو العربيّ، وهذا ما نلحظه في كثير من أبواب النَّحو، وفي باب (لو) نلمس هذا، فنجدها تارة تكون شرطية وأخرى للتمني ومصدرية ... إلخ، فضلاً عن اختلافهم فيما يأتي بعد (لو) أ اسم هو أم فعل؟ وإن كان فعلاً أ ماضٍ هو أم مستقبل، وغيرها من الأمور الخلافية، وقد آثرت الوقوف على بعض المسائل النَّحويَّة في (لو) لا كلها، عسى أن ندون بعض الشيء عنها بعد مناقشة تلك الأوجه الخلافية، مرجحين بعض الأمور، ومفسِّرين الأوجه التي نراها قريبة من السَّبب الذي دفعهم إلى وضع قاعدة أخرى، ولعلهم لو أخذوا بنظر الاعتبار هذا السَّبب عند وضع القاعدة الأصل لَمَّا اضطروا إلى كثرة التَّعليل والتَّـقدير.
