Authors: Abdikeev N. M. , Bogachev Yu. S. , Moreva E. L.
Published: June 2019

The need to ensure the transition of Russia to the six technological mode, of creation of the adequate conditions for this and effective management of such a transition, make the authors turn to the analysis of modern mechanisms used for this purpose, including the state stimulation of the manufacturing industry, which has a leading role in the consolidation of such a transition. The difficulties faced by our country in this task make us turn to the study of the experience of foreign countries that have succeeded in this transition. These includeGermany,Japanand theUnited States, which have long been the steady leaders in the development and use of advanced technologies and in the development of the manufacturing industry as well. The subject of our study was the assessment of the mechanisms of state incentives for manufacturing industry used in countries with developed market economies, through the prism of the objectives and approaches to the functional purpose of the sector. The aim of the study was a determination of the limits of effective use of the mechanisms of state stimulation of the manufacturing industry inGermany,Japanand theUnited States. The methodological basis of the study was: general scientific methods of cognition and research, including system and logical methods, analysis, synthesis, analogy; branch scientific methods, such as economic comparative studies, etc. The analysis of the use of mechanisms of state stimulation of the manufacturing industry in Germany, Japan and the United States shows that the effective use of well-established and well-known in the world mechanisms of state stimulation of manufacturing industry requires in each case a separate integrated and balanced approach to their application with a clearly defined target focus of such use, as well as taking into account the specifics of the entities to which they are addressed, and the multilevel environment in which they operate.
Characteristics of Instability of Standard and Non-standard Employment in Contemporary Russia
Authors: Bobkov V. N.
Published: June 2019

Precarious employment is becoming more and more widespread in the world and inRussia. It is the destruction of the traditional standard model of employment, labour and social rights of workers to secure and sustainable employment. This is one of the problematic areas of modern social relations, exacerbated by the industrial revolution 4.0, globalization of global relations in all areas and their use in the interests of national and world capital. In the article, the author characterizes the essence of precarious employment and presents the results of a sociological study of precarious employment in a representative group. It allowed expanding the sociological tools of its study and the use of sociological indicators to identify groups of workers in relation to precarious employment. The author also studied the parameters of the specified representative group, clarified the indicators of precarious employment and their quantitative values that identify certain aspects. As a result, the author identified four profiles of contemporary employment inRussia, characterized by increasing signs of precarious employment and gave their comparative characteristics. Further, the author described the differences in socio-demographic, socio-labour and economic characteristics of workers belonging to different profiles of employment. On this basis, the author justified the need to transform labour, civil and other legislation, which would allow more fully using the advantages of standard and ﬂexible employment for employees of various segments of the Russian labour market, ensuring, at the same time, compliance with their labour and social rights.
Assessment of Average Market Investment Returns in Development of the Residential Real Estate in the Moscow Region
Authors: Sternik S. G. , Mironchuk Ya. S. , Filatova E. M.
Published: June 2019

In the previous work, G.M. Sternik and S.G. Sternik justified the options for the method of assessing the average current annual return on investment in residential real estate development, depending on the nature and content of the initial data on the costs contained in the sources of information (construction costs or total investment costs). Based on the analysis of the composition of the elements of development costs used in various data sources, we corrected the coefficients that allowed us to move from the assessment of the current annual return on investment in development in relation to the cost (full estimated cost) of construction to the assessment of the current annual return on investment in relation to the total investment costs. This calculation method was tested on the example of the housing market inMoscow. As a result, we concluded it is possible its use for investment management in the housing market. In this article, based on G.M. Sternik and S.G. Sternik’s methodology for assessing the return on investment into the development, and taking also into account the increase of information openness of the real estate market, we improved the calculation formulas, using new sources of the initial data, and recalculated the average market return on investment into the development of residential real estate in the Moscow region according to the data available for 2014–2017. We concluded that, since 2015, the average market return on investment takes negative values, i.e. the volume of investment in construction exceeds the revenue from sales in the primary market. However, in the second half of 2017, the indicator has increased to positive values, which was due to a greater extent of the decrease in the volume of residential construction in the region. The data obtained by us, together with the improved method of calculations, allow predicting with high reliability the potential of the development of the regional markets of primary housing for the purpose of investment and state planning of housing construction programs.
The Assessment of the Impact of Sanctions on Russia for Oil & Gas Industry and Defence Industry Complex of Russia
Authors: Kazantsev S. V.
Published: June 2019

The article presents the results of the author’s research of the impact of a wide range of restrictions and prohibitions applied to theRussian Federation, used by a number of countries for their geopolitical purposes and as a means of competition. The object of study was the impact of anti-Russian sanctions on the development of Oil & Gas industry and defence industry complex ofRussiain 2014–2016. The purpose of the analysis was to assess the impact of sanctions on the volume of oil and gas production, the dynamics of foreign earnings from the export of oil and gas, and of foreign earnings from the sale abroad of military and civilian products of the Russian defence industry complex (DIC). As the research method, the author used the economic analysis of the time series of statistical data presented in open statistics and literature. The author showed that some countries use the anti-Russian sanctions as a means of political, financial, economic, scientific, and technological struggle with the leadership ofRussiaand Russian economic entities. It is noteworthy that their introduction in 2014 coincided with the readiness of theUSto export gas and oil, which required a niche in the international energy market. The imposed sanctions have affected the volume of oil production inRussia, which was one of the factors of reduction of foreign earnings from the country’s oil and gas exports. However, the Russian defence industry complex has relatively well experienced the negative impact of sanctions and other non-market instruments of competition
Forecasting the volatility of Financial Time Series by Tree Ensembles
Authors: Vidmant O. S.
Published: June 2019

The use of new tools for economic data analysis in the last decade has led to significant improvements in forecasting. This is due to the relevance of the question, and the development of technologies that allow implementation of more complex models without resorting to the use of significant computing power. The constant volatility of the world indices forces all financial market players to improve risk management models and, at the same time, to revise the policy of capital investment. More stringent liquidity and transparency standards in relation to the financial sector also encourage participants to experiment with protective mechanisms and to create predictive algorithms that can not only reduce the losses from the volatility of financial instruments but also benefit from short-term investment manipulations. The article discusses the possibility of improving the efficiency of calculations in predicting the volatility by the models of tree ensembles using various methods of data analysis. As the key points of efficiency growth, the author studied the possibility of aggregation of financial time series data using several methods of calculation and prediction of variance: Standard, EWMA, ARCH, GARCH, and also analyzed the possibility of simplifying the calculations while reducing the correlation between the series. The author demonstrated the application of calculation methods on the basis of an array of historical price data (Open, High, Low, Close) and volume indicators (Volumes) of futures trading on the RTS index with a five-minute time interval and an annual set of historical data. The proposed method allows to reduce the cost of computing power and time for data processing in the analysis of short-term positions in the financial markets and to identify risks with a certain level of confidence probability.
The Problems of Matching Objectives, Instruments, and Financial Flows in Regional Policy
Authors: Barbashova N. E. , Gerasimova Yu. V.
Published: June 2019

In the article, authors considered the relationship between the priorities of the regional policy of theRussian Federation, the applied instruments, and the corresponding financial ﬂows. The study was conducted on the basis of the analysis of normative legal acts of the Russian Federation in the field of regional policy, budget policy and strategic planning, as well as strategic and program documents of the Federal level. The authors paid special attention to the instruments of stimulation of regional economic development. The authors came to the conclusion that the successful implementation of regional policy is hampered by the problems associated with the incompleteness and inconsistency of the system of strategic planning documents, the lack of interdepartmental coordination, the redundancy of the number of incentive mechanisms, the complexity of managing financial ﬂows from various sources, and the gaps in information support. The findings of the study were tested on the example of the Primorsky Krai. According to the analysis, the authors have formulated recommendations for public authorities aimed at improving the effectiveness of incentive mechanisms of state regional policy.
Dialectical Interrelation of Types of Monetary and Settlement System and Division of Labour
Authors: Reshetova L. V.
Published: June 2019

The relevance of the research the author connects to the necessity of selecting from the wide range of digital technologies the best instruments for economic development. The aims of the article are: to prove the interrelation between the settlement mechanisms and systems of the division of labour; the classification of monetary systems by the differences in the division of labour systems; the rationale the optimality of the public-state monetary and settlement system. The study was conducted using a dialectical method, positive and normative institutional and macroeconomic methods. The results of the study are possible to use unified methods of coordinating the sphere of basic industries and the sphere of innovative, creative work in a digital economy. The author proposes to coordinate the division of labour in the basic sectors and an inter-branch balance within the framework of an automated management system. To coordinate the types of innovative, creative work, a system of combining the spheres of social development through a “circular advance” is possible. These coordination instruments we can implement in the transition to the optimal monetary and settlement system. Monetary and settlement instruments for coordination of the sphere of real production can be used to achieve state regulation in the basic branches of the economy, and instruments for the formation of vertically integrated links, at least, in the sphere of innovative, creative work. The optimal monetary and settlement system proposes the existence of endogen money — the means of account. Such a system makes it possible to use the dynamic model of the inter-sectoral balance as an instrument of the digital economy in the sphere of basic production and instruments of endogenous, monetary-calculating ways of forming links in the vertical division of labour for the innovative, creative sphere. It promotes to innovative and creative work, overcoming market and planning constraints. Investigation of the possibilities of monetary and settlement instruments can generate discussion end can determine other areas of their use.
Inflation Forecasting: The Practice of Using Synthetic Procedures
Authors: Balatskiy E.  V. , Yurevich M. A.
Published: June 2019

The article contains a review of inflation forecasting models, including the most popular class of models as one-factor models: random walk, direct autoregression, recursive autoregression, stochastic volatility with an unobserved component and of the integrated model of autoregression with moving average. Also, we discussed the possibilities of various modifications of models based on the Phillips curve (including the “triangle model”), vector autoregressive models (including the factor-extended model of B. Bernanke’s vector autoregression), dynamic general equilibrium models and neural networks. Further, we considered the comparative advantages of these classes of models. In particular, we revealed a new trend in inflation forecasting, which consists of the introduction of synthetic procedures for private forecasts accounting obtained by different models. An important conclusion of the study is the superiority of expert assessments in comparison with all available models. We have shown that in the conditions of a large number of alternative methods of inflation modelling, the choice of the adequate approach in specific conditions (for example, for the Russian economy of the current period) is a non-trivial procedure. Based on this conclusion, the authors substantiate the thesis that large prognostic possibilities are inherent in the mixed strategies of using different methodological approaches, when implementing different modelling tools at different stages of modelling, in particular, the multifactorial econometric model and the artificial neural network.
Environmental Issues in a Digital Economy
Authors: Perelet R. A.
Published: June 2019

Digital technologies play a crucial role in achieving the long-term balance between the techno-sphere and the natural environment that is necessary for sustainable development. The digital economy is a relatively new concept in national policymaking, often using such terms as “information economy” (the 1970s), “knowledge economy” and “electronic economy” (the 1980s), “new economy” (the 1990s) or “network economy” and “Internet economy” (the 2000s). While there is no single definition of the digital economy, there is general agreement on some fundamental principles. The basic idea of a digital economy is that products, services, lifelong learning and innovation are made possible by the computerised transfer and processing of modern technology in the context of market globalisation and sustainable development. Sustainable development is largely related to the preservation of the biosphere and natural capital together with the techno-sphere and the socio-sphere. However, in real life, environmental aspects are often overlooked. In recent years, there have been changes in the formation of the economies of countries, especially in strengthening their environmental component. Reducing the cost of sensor technology and the spread of networks allow you to connect each component entering the production process. The data collected through such connections provide an opportunity to know the place of origin of the product, the method of production and the amount of energy spent on its production. Information received on their basis gives to companies, cities and whole countries the opportunity to restore, create, and to relocate these resources more effectively. It is proposed to take into account the impact of the digital economy on the environment. The EU response is increasingly seen as a strong combination of the knowledge economy and the green new deal.
Advantages and Disadvantages of Signing a Comprehensive Economic and Trade Agreement (CETA) for the Еconomies of the EU and Canada
Authors: Baryshnikov P. Yu.
Published: June 2019

This article presents an analysis of the main provisions of the Comprehensive Economic and Trade Agreement (CETA) signed by the government of Canada and the European Parliament at the end of 2016. In particular, the author analysed such aspects of the agreement as the abolition of customs tariffs, the introduction of common quality standards, access to the procurement market, modification of the system of investment disputes, etc. According to the results of the study, there was a mixed effect of the agreement for both Canada and the EU. For some sectors of the economies of the participating countries, the implementation of the CETA promises to create exceptional conditions for development, while for others the signing of a multilateral agreement is unprofitable or means losses. It should be noted that at the present stage the pros and cons of the СЕТА can be considered only at the theoretical level. It will be possible to draw objective conclusions about the impact of the multilateral trade agreement on the development of trade and economic relations between the countries only a certain time later after the ratification of the agreement by all parties. At the current stage of development of Canada-EU relations within the framework of the СЕТА, it can be noted that only the dynamic development and further improvement of the mechanisms of the multilateral agreement will make a trade and economic relations between the countries more open and transparent.

Authors: Obianyo Jude Iloabuchi , Agunwamba J. C.
Published: June 2019

Efficiencies of sedimentation tanks with horizontal and vertical baffle mixers were studied, compared, and also to determine the optima values of factors of clarification in the sedimentation tanks. These are the discharge, basin baffle spacing and dosing factors, thereby comprises three factors at five levels for a 5k factorial design model. 2.0 mg/l of clay solution was introduced into the basin at discharge rates of 48.75 ml/s, 55.07 ml/s, 60.34 ml/s, 62.45 ml/s and 63.27 ml/s respectively. Alum solution was introduced as coagulant at the inlet of the basin, samples were collected both from the basin and the outlet and concentrations of flocs were measured. Plots of variation of total outlet and average outlet floc with dosing rates for horizontal and vertical mixers show that vertical mixers are better only at discharge of 48.75 ml/s, but horizontal mixers are better at 55.05 ml/s, 60.34 ml/s, 62.45 ml/s and 63.27 ml/s.  Variation of grand total floc with dosing rates is also in favour of horizontal mixers. Plots of outlet floc against dosing rates at 48.75 ml/s discharge show that horizontal mixer spaced at 100 mm is better with maximum sediment/floc of 333  10-4 g at a dosing rate of 0.55 ml/s, at 55.07 ml/s discharge vertical mixer is better with 250 mm spacing giving maximum sediment of 985 10-4 g at a dosing rate of 0.95 ml/s. For 60.34 ml/s discharge, horizontal mixer is better at 250 mm spacing with maximum sediment of 307  10-4 g at 0.75 ml/s dosing rate. In the case of 62.45 ml/s discharge, horizontal mixer at a spacing of 300 mm is better with a maximum deposit of 335  10-4 g at a dosing rate of 0.95 ml/s, and for discharge of 63.27 ml/s, horizontal mixer is better at 150 mm spacing having a maximum sediment of 715  10-4 g for a dosing rate of 0.35 ml/s. Response surface methodology (RSM) presented by Montgomery, 2008  was further used for the analysis of data in this study for more reliable inference because it optimized the responses of these three variables. It was observed that for the vertically placed baffles, the stationary points of response surface for discharge rate, baffle spacing and dosing rate are 80.56762847 ml/s, 100.00000 mm and 0.04965779 ml/s, while for horizontally placed baffles, it was 70.636018 ml/s, 332.864704 mm and 1.402526 ml/s, however, these results indicate that horizontally placed baffle mixers are better than vertically placed baffle mixers.

The data employed in this research were time series data. The analysis used the model of demand, supply and stock of palm oil. Full simultaneity in a dynamic model with inventories was adopted from Nerlove (1956). This research has shown that the supply of palm oil in the foreign market had a positive influence on the price, the area and the supply in previous years while the response of the demand was negative. On the other hand, the income and the demand in the previous years had a positive influence. The palm oil stock was influenced by the quantity in the previous years and international price.
SOME INSTRUMENTS USED TO ACHIEVE ENVIRONMENTAL PERFORMANCE IN TOURIST ACCOMMODATION UNITS
Authors: Stefanica Mirela
Published: June 2019

The paper highlights some instruments that help us to achieve environmental performance in tourist accommodation structures. The most known instruments used to achieve environmental performance are as follows: ISO 14001 standards (Environmental Management Standard), EMAS (European Eco-Management and Audit Scheme), and EU ECOLABEL. With the help of these instruments, we can identify and quantify the material and power resources consumed, the emissions and waste generated, we can evaluate their potential impact over the environment, and we can identify the options to reduce these impacts. The reasons at the basis of the creation of these instruments are extremely complex, going beyond the purely economic frame in order to enter an ethical sphere of debates inciting the spirit of almost all the population on the Globe, which is the type of planet that we leave as inheritance to our followers, the future generations. According to the reports of the European Commission regarding these instruments we have shown the evolution and the present situation of EMAS registrations and EU Ecolabel for European tourist accommodation services.

Published: June 2019

Artikkelissa tarkastellaan, mitä kuormittavia tekijöitä sosiaalityössä esiintyy ja millaisia muutoksia niissä on tapahtunut 2000-luvun Suomessa. Artikkelin pohjana oleva tutkimus kohdentui sosiaalityöntekijöihin. Vertailuryhminä olivat erityisopettajat, psykologit ja lastentarhanopettajat. Aineistona käytettiin Työterveyslaitoksen Kunta10-tutkimusaineistoa, jota Työterveyslaitos on kerännyt vuodesta 1997 lähtien. Analyysimenetelminä käytettiin lineaarista regressiota poikkileikkausaineistoon ja lineaarista latenttia kasvukäyrämallia toistomittaus- ja seka-aineistoon. Artikkelissa keskityttiin työn hallintaan, työn palkitsevuuteen ja työn paineisiin. Ammattiryhmien välillä havaittiin eroja: sosiaalityöntekijät kokivat enemmän kuormitusta työssään kuin psykologit, erityisopettajat tai lastentarhanopettajat. Työhön liittyvissä psykososiaalisissa tekijöissä ei havaittu olennaista muutosta vuosina 2000–2012 missään tutkituista ammattiryhmistä. Vaikuttaa siltä, että työn luonne tutkituissa ryhmissä on pysynyt samankaltaisena.

Published: June 2019

Objective: To measure the doses of occupational radiation to which a physician who performs orthopedic surgery of the foot and ankle using a fluoroscopy device is exposed during work and to compare those doses with the values provided in the current legislation and propose measures of radioprotection. Methods: Thermoluminescent dosimetry (TLD) was used to measure radiation in critical target areas (whole-body, lens, thyroid, right and left hands) of the surgeon’s body during all the surgical procedures performed by him between 12/19/2017 and 2/5/2018. From the mean dose values obtained for the procedures, the dose of annual radiation exposure was estimated for each of the regions analyzed and compared with the current legislation. Results: The estimate of the annual radiation dose received by the surgeon to the chest region, above the lead apron, was 5 times higher than that established by the national legislation. However, considering the use of the lead apron, the dose was acceptable. Estimates of equivalent doses for the limbs and thyroid had results within the levels required by the current legislation. The equivalent dose for the lens, on the other hand, was 4 times higher than that established by the legislation. Conclusion: During the workday, the foot and ankle orthopedic surgeon is exposed to doses of radiation higher than those considered acceptable. The data corroborate the need to wear radiological protective clothing, especially a lead apron and goggles. Level of Evidence IV; Prognostic Study; Case Series.

Determinantes da participação dos domicílios em acordos de pesca no Baixo Amazonas, estado do Pará
Authors: Schons Stella Zucchetti
Published: June 2019

Este artigo tem por objetivo discutir diferentes fatores que contribuem para a tomada de decisão de domicílios da várzea do baixo rio Amazonas, no Pará, de participar ou não dos esforços de implementação de acordos de pesca comunitários. Como resultado da aplicação de um modelo econométrico Probit a dados coletados junto a cerca de 650 domicílios em dois momentos do pulso das águas do rio Amazonas, tem-se que maiores valores do benefício do seguro defeso e históricos mais longos de participação nos acordos de pesca contribuem para a decisão de participação nesses acordos. Além disso, a produtividade na atividade da pesca, dentre outros fatores demográficos e exógenos, também contribui para aquela decisão. Esses resultados indicam a relevância do papel do governo e do compromisso moral com a comunidade, assim como o potencial benéfico da assistência técnica de qualidade para o sistema de comanejo da pesca da região.

Teacher leadership for organizational change
Authors: Damkuvienė Milda , Valuckienė Jūratė , Balčiūnas Sigitas
Published: June 2019

The aim of this article is to test the teacher leadership initiated by teacher professional development abroad, as a factor of organisational change in a structural equation model. Structural equation modelling was employed to analyse survey data collected from 218 teachers who participated in professional development activities abroad under Erasmus+ KA1 in 32 Lithuanian schools. The model expresses the relationship between teacher leadership and organizational change, where teacher professional development abroad is treated as an initial (self-development) dimension of teacher leadership. Results revealed the positive and significant relationship between teacher leadership and organizational change, where leadership is conceptualized as an ongoing relational process of selfdevelopment, dispersing ideas, involving others and gaining commitment. Findings of the study also depicted a positive and significant relationship of didactic competence (the dimension of self-development phase of leadership) with one of the dimensions of organizational change - learning in the classroom.
Cooperation between head teachers and professional school counsellors in Slovenian schools
Authors: Gregorčič Mrvar Petra , Resman Metod , Kalin Jana , Mažgon Jasna
Published: June 2019

The characteristics of cooperation between head teachers and school counsellors are presented theoretically and empirically. Distributed leadership means that head teachers do not lead schools through school-based educators but rather together with them, with school counsellors playing an important role. Numerous research studies demonstrate that a strong head teacher–school counsellor relationship is a crucial component of meeting the vision, goals and well-being of the school. The findings of our research study, conducted among head teachers and school counsellors, show positive attitudes of both groups towards mutual cooperation. Both considered the cooperation to be good or very good, the head teachers rated it even better. It is interesting to observe that the head teachers found more support in school counsellors than vice versa. Also, more of the head teachers said they saw school counsellors as partners than did the school counsellors. It thus remains to be seen how school counsellors’ perception of the school leadership’s support in their work could be strengthened and how head teachers could be encouraged to support the work of the school counselling service even more, so that this relationship becomes reciprocal and that each party’s ability to perform their work will be enhanced by the strong relationship.
Teacher leadership in Lithuania
Authors: Brandisauskiene Agne , Cesnaviciene Jurate , Bruzgeleviciene Ramute
Published: June 2019

Over the past 25 years, Lithuania has established a system of education based on humanistic and democratic relationships. In this system, teacher leadership is highly important, as it serves as the basis for school community “reculturisation” and improvement. The aim of the current article is to overview the situation of teacher leadership in Lithuania, emphasising the aspect of teacher cooperation. The three characteristics of Lithuanian teacher leadership that we present demonstrate that teacher cooperation remains a challenge in the country. Teachers are reluctant to discuss and render improvement proposals, and lack experience of teamwork. Nevertheless, it is to be expected that the ongoing project “Time for Leaders,” will produce the necessary cultural change required to create a learning network of teachers and establish genuine, open and professional dialogue.

Penggunaan berulang minyak goreng kelapa sawit akan mengalami kerusakan apabila mengalami pemanasan berulang, kontak dengan air, udara, dan logam. Kerusakan minyak dapat dicegah dengan menambahkan antioksidan, karena senyawa antioksidan ini dapat menghambat proses kerusakan minyak terutama oksidasi. Penelitian ini menggunakan ekstrak bawang merah sebagai antioksidan alami.

Minyak goreng kelapa sawit sebelum digunakan untuk penggorengan ditetapkan sebagai kontrol tanpa penyimpanan 24 jam (P0) dan dengan penyimpanan 24 jam (P024). Minyak goreng kelapa sawit digunakan untuk menggoreng tempe dengan pengulangan penggorengan pertama, kedua, dan ketiga. Perlakuan yang diberikan dengan penambahan ekstrak bawang merah dan tanpa ekstrak bawang merah. Penetapan bilangan peroksida pada penggunaan berulang minyak goreng kelapa sawit dilakukan dengan metode Iodometri.

Hasil penelitian diperoleh bilangan peroksida pada minyak goreng kelapa sawit sebagai kontrol tanpa penyimpanan 24 jam (P0) dan Kontrol dengan penyimpanan 24 jam (P024) adalah 1,79 mek O2/kg dan 2,92 mek O2 /kg, selanjutnya pada perlakuan minyak goreng kelapa sawit tanpa ekstrak bawang merah pada P1, P2, P3 adalah 9,72 mek O2 /kg, 11,11 mek O2 /kg, 12,35 mek O2 /kg, sedangkan pada perlakuan minyak goreng kelapa sawit dengan penambahan ekstrak bawang merah pada P1, P2, P3 adalah 5,29 mek O2 /kg, 6,63 mek O2 /kg, 9,19 mek O2 /kg. Berdasarkan hasil penelitian membuktikan bahwa terdapat pengaruh yang nyata antara minyak goreng kelapa sawit tanpa penambahan ekstrak bawang merah dandengan penambahan ekstrak bawang merah.

As plataformas de mídias sociais transformaram-se em instâncias oficiais governamentais, representam um caminho para o exercício da expressão e opinião individual e coletiva e engajamento da sociedade civil em discussões político-sociais. Esse canal de participação digital, na medida em que contribui para o alcance da meta 16.7 dos Objetivos de Desenvolvimento Sustentável (ODS) da Agenda 2030 da Organização das Nações Unidas (ONU), cria novos desafios para a comunidade de profissionais da informações em suas áreas de pesquisa. Um desses desafios está diretamente relacionado à existência de uma estrutura administrativa com tratamento informacional. Com base nessas reflexões, o objetivo deste trabalho é discutir a necessidade da documentação de mídias para além das plataformas, indicar técnicas de arquivamento já existentes e enfatizar o processo de indexação como uma etapa importante para acesso e recuperação da informação, apontando alguns desafios emergentes encontrados no processo de indexação de mídias digitais. Para alcançar os objetivos propostos, uma pesquisa bibliográfica foi realizada em três bases de dados bibliográficas: Library and Information Science, Science Direct e Google Scholar. Como critérios para refinamento conceitual, foram utilizados filtros para inserção dos idiomas inglês, espanhol e português, sem período pré-estipulado para a consulta já que se trata de uma temática recente na Ciência da Informação e na literatura como um todo. Conclui que esse tipo de informação gerada em mídias sociais representa um insumo informacional diferenciado que apresenta inúmeros desafios relacionados à sua documentação, especialmente o processo de indexação, como prática profissional no tratamento temático para a recuperação da informação, que conduzirá os mecanismos de busca.
Eye-tracking the effect of semantic decoding on orthographic learning in Chinese

Published: June 2019

Most Chinese compound characters represent meaning explicitly and systematically via the semantic radical. Previous research has shown that readers can use the semantic radical to infer the meaning of unknown compound characters (i.e., semantic decoding). Yet it is unclear whether it influences reading in natural texts or facilitates orthographic learning. Across two eye-tracking experiments, we exposed adult native speakers (n= 25 and n=16) to sixteen pseudocharacters embedded in sentences. Half of the pseudocharacters contained semantic radicals related to the meaning conferred by the sentential context (i.e., transparent); the other half were unrelated (i.e., opaque). After reading, participants completed written cloze, orthographic decision and definition production tasks. In both experiments, eye-tracking results showed a reduction in fixation times and regressions over the five exposures for the pseudocharacters. The post-test outcomes provided evidence for orthographic and semantic learning. There was no difference in eye-movement measures or in written cloze and orthographic decision between transparent and opaque items, but definition was better for the transparent pseudocharacters. We conclude that semantic decoding does not affect the reading of novel compound characters in natural texts or orthographic learning, but that it does seem to assist in learning semantics.

Thermal conductivity in the boundary layer of heat exchange surface is the crucial parameter of adsorption process efficiency which occurs in the adsorption bed. In order to improve heat transfer conditions in the adsorption chiller, novel constructions of adsorption beds are currently investigated. The porous structure of the sorbent layer causes low thermal conductivity in the adsorption bed. One of the methods to improve heat transfer conditions is a modification of porous media bed structure with glue which is characterized with higher thermal conductivity. The optimum parameters of sorbents and glues to build the novel coated construction, in terms of improving the chiller Coefficient of Performance (COP) were defined in (Grabowska et al. 2018a). The paper implements fuzzy logic approach for predicting thermal conductivity of modified porous media layers. The developed model allows determination of the sorbent layer thermal conductivity based on various input parameters: arithmetic average of particle distribution d, density ρ and thermal diffusivity k. The data from empirical research was used to build up the model by fuzzy logic methods.

La CBCT (cone beam computed tomography), es un gran avance en el diagnóstico por imágenes. Se basa en la reconstrucción de imágenes en 3D para un diagnóstico más acertado. El presente estudio tiene por objeto esUtundiivaer rlasidmaodrfoClaotgóíalicdae dloes canales radiculares del primer premolar superior, utilizando radiografía periapical y tomografía de haz cónico.

El tipo de estudio es in vitro, descriptivo y transversal, la muestra es por conveniencia, puesto que no se dispuso de una población específica para guia, por lo que se seleccionaron 50 dientes (Primeros Premolares Superiores), extraídos por motivo ortodóntico. Las imágenes obtenidas mediante radiografías intra orales revelan una información en dos dimensiones, lo que nos limita en el diagnóstico. En determinadas situaciones la visualización en tres dimensiones de un problema endodóntico es necesaria. El resultado del presente estudio denota que radiográficamente se obtienen datos acertados sobre la morfología de las piezas que presentaban un solo conducto o dos raíces separadas, siendo más efectivo el uso de la tomografía para la descripción de piezas con un sistema de conductos más complejo.
