Політико-психологічні маніпуляції у передвиборчій кампанії президента України 2019 року
Authors: Лагута Андрій
Published: December 2019

Стаття присвячена темі, що завжди актуальна для демократичних сус­пільств, — маніпуляцій у передвиборчих кампаніях. Оскільки медіаграмотність як освітня дисципліна не впроваджена в широкий загал в українському суспільстві — це призводить до того, що громадськістю маніпулюють, спотворюючи реальність. Саме використання різних технік, «брудних» технологій, тактик та стратегій маніпуляцій утруднює існування демократії.На основі медіадослідження (використання електронних джерел, соціальних мереж та відеохостингів) автор аналізує те, які маніпуляційні стратегії (за типологією Н. Хомського) були використані кандидатами у передвиборчій кампанії Президента України 2019 року, а також вплив технік і технологій, що були використані в рамках маніпулятивних стратегій.Було досліджено здійснення вербального і невербального впливу на електорат: лінгвістично, психологічно, нейролінгвістично; були проаналізовані міміка, жести кандидатів; зауважено як посил до емоційно-підсвідомої складової суспільства може стати вирішальним у передвиборчій гонці, яким чином «відволікання від важливого» може сприяти кандидату сформувати свій імідж. Також розглянуто архетипи, які використовувалися в передвиборчій кампанії, їх суть і значення для суспільства, «навішування ярликів»; поступовість рішень, що зробили кандидата популярним серед громадськості; тренди, котрі були створені іміджмейкерами кандидатів задля підвищення рейтингу та підтримки. З’ясовано як можна використати «провину» на свою користь; відстежено маніпуляції соціологічними дослідженнями; розмову з народом, як з дитиною і гру в «простонародність». Автором досліджено як гіперболізація фактів без порівняння може викликати серйозне обурення суспільства та зруйнувати імідж опонента. Був проведений ґрунтовний аналіз впливу на маси, який застосовувався за допомогою маніпулятивних технологій і стратегій.Об’єктом дослідження було обрано передвиборчі кампанії трьох кандидатів: В. Зе­ленського, П. Порошенка, Ю. Тимошенко.

Published: December 2019

Relevance. It is relevant to develop new technological solutions for palliative surgical treatment of patients with unresectable pancreatic head cancer (UPHC), since the incidence of postoperative complications in such patients reaches 25 %, and mortality – 20 %.
Objective. To improve the diagnosis and immediate results of palliative surgical treatment of patients with UPHC complicated by obstructive jaundice, duodenal obstruction, and carcinomatous pancreatitis.
Materials and methods. At the first stage of the study, criteria for the diagnosis of PHC complications, tactics and methods for their surgical correction were evaluated (group I, 159 patients). After analyzing the results, a new technology for the surgical treatment of patients is formulated, the clinical testing of which was carried out in the second stage. An open, prospective, randomized study included 112 patients with UPHC complicated by obstructive jaundice (group II), who underwent palliative surgical treatment using patented surgical procedures. A comparative analysis of the results of surgical treatment of patients of both groups was carried out.
Results. The safety and effectiveness of the simultaneous implementation with biliodigestive gastrodigestive shunting has been proven. The advantages of the tactics of two-stage surgical treatment of patients with signs of liver failure are shown. In patients with high anesthetic and surgical risk, the replacement of open surgery with endoscopic prosthetics of the biliary system and duodenal obstruction is justified. In severe forms of carcinomatous pancreatitis with expansion of the main pancreatic duct, a technique for combined bilio- and pancreatodigestive shunting is proposed. When multiple organ dysfunctions with hepatic-renal, hemorrhagic syndromes are formed in patients with obstructive jaundice, decompression of the biliary system by minimally invasive techniques is shown in the first stage, and the main stage of surgical intervention in the second. As a result, the incidence of postoperative complications was 9,8 %, mortality – 3,7 %.
Conclusions. In patients with UPHC cancer complicated by obstructive jaundice, performing instead of traditional biliodigestive bypass surgery combined bilioastrodigestive bypass surgery is a safe procedure that does not increase the frequency of postoperative complications, prevents the need for repeated gastro-digestive interventions, improves the quality of life of patients in the long-term postoperative period. The operation of choice in the surgical treatment of patients with UPHC complicated by obstruction of the biliary system and duodenum with high surgical and anesthetic risk is endoscopic interventions with endoscopic prosthetics of the bile ducts and duodenum.

Authors: Morozova N.L. , Tkachenko M.M. , Romanenko A.A.
Published: December 2019

Relevance. The viability of patients is determined by the degree of lung injury despite the fact that cystic fibrosis (CF) is a multiple organ disease. Early diagnosis and adequate treatment complex of cystic fibrosis prolong the lives of patients and improves its quality. Therefore, timely and detailed diagnosis of cystic fibrosis lung is particularly important problem. The central role for its solution belongs to radiological studies.     Objective. To refine the radiology’s capabilities in detecting lung changes in case of cystic fibrosis in adult patients and to determine the role of the computed tomography (CT) in the diagnostic process. Materials and methods. The results of radiography and CT scans of 15 patients, for whom the diagnosis of CF was established in adulthood, were analyzed. Results. The most typical radiographic and CT signs of lung damage were determined in adult CF patients. It has been shown that the radiographic changes in the lungs are non-specific for CF patients and are determined by the secondary inflammatory process. The diagnostic capabilities of CT scans in detecting subtle structural changes in the lung tissue and bronchial tree are underlined, which allows to diagnose light and atypical forms of CF in adults, determinate the stage and activity of the pathological process and the effectiveness of the treatment. Findings. The radiation studies were able to define the CF’s specific symptoms of lung lesions. Radiography of the thoracic cavity’s organs is a necessary step in the preliminary diagnosis for adult patients with CF or in the medical emergency's cases. The CT has the greatest diagnostic value in detecting subtle structural and functional specific changes of CF. The regular monitoring using CT scans is necessary for improving the control of the respiratory organs’ state and determine the further tactics for the particular patient.
On some methodological problems of digital transformation of education
Authors: Testov V. A.
Published: December 2019

The purpose of the article is to consider the main directions of digital transformation of education and methodological problems arising in this process. The analysis of the literature shows that pedagogical science does not keep pace with the rapid process of digital transformation of education, a unified methodological base has not been developed, there is no common understanding of this process in the scientific community and of new scientific terms that are being formed in this process. There is also no scientific justification for the ongoing changes in education. Continuous process of reforming, modernization, improvement of educational systems does not yield results, but leads to accumulation of fatigue of teachers from reforms, emergence of psychophysiological and methodical problems in training. When reforming the content of education, mistakes are made associated with insufficient reliance on fundamental pedagogical knowledge, lack of balance between traditions and innovations in education. The emerging problems can be solved only as a result of the development of a common methodological framework and common scientific approaches in the digital transformation of education.

The article discusses the conditions for the use of computerized dynamic adaptive tests to provide developing training and monitoring in the field of foreign language education. Dynamic adaptive test simulators used as a tool for personalizing and monitoring foreign language education are still insufficiently represented in the educational practice of the Russian Federation. The authors of the article offer recommendations on the use of dynamic adaptive audio test simulators for monitoring foreign language education. As indicators of monitoring, the parameters characterizing the learning ability of students are considered: feedback coefficient; the complexity and time pace of learning activities of students of a foreign language.

The purpose of the article is to present authors’ recommendations on the implementation of dynamic adaptive audio test simulators based on evaluative feedback in the field of foreign language education, providing for monitoring the quality of bilingual education based on the integration of individualized learning and dynamic adaptive testing of educational activities.

The research methodology is an analysis of the use of existing dynamic adaptive test simulators in the field of foreign language education; studying the results of interdisciplinary studies of domestic and foreign scientists on the creation and use of dynamic adaptive tests for the learning process as a whole and the creation of dynamic adaptive tests for foreign education in particular; analysis and generalization of the author’s experience of using dynamic adaptive audio tests simulators as a tool for monitoring educational activities in the field of foreign language education.

Results of the reseach are: authors developed computerized dynamic adaptive audio test simulators based on evaluative feedback in the field of foreign language education; indicators of monitoring the learning process in the field of foreign language education are identified, including the total feedback coefficient, actiograms, time pace and laboriousness; testing was carried out and recommendations were given for the use of dynamic adaptive audio test simulators for monitoring educational activities in the field of foreign language education.

Analyzing the results of testing dynamic adaptive audio test simulators in a foreign language, the authors conclude that their use in practice implements personalized dynamic monitoring of the process of teaching foreign languages, thereby improving the quality of teaching foreign languages. Dynamic adaptive audio test simulators can provide monitoring of the dynamics of the process of teaching native and foreign languages.
Ensuring readiness for teachers to forming at school future specialists of digital economy on the base of the concept of open educational resources
Authors: Starichenko B. E.
Published: December 2019

The article discusses the need to attract school teachers of mathematics and computer science to implement the program “Personnel of the digital economy”. The problem is the steady reduction in recent years in the share of school graduates who choose the exam in specialized mathematics, which does not allow them to continue their studies at universities to acquire IT specialties. This casts doubt on the achievement of the indicators of the program “Development of the Digital Economy of the Russian Federation” in part of staffing of digitalization. To implement the plans, it is necessary to solve the problem of creating the appropriate professional focus of schoolchildren. This, in turn, requires bringing the system of training and retraining of teachers of mathematics and computer science at universities in line with the provisions of the Program in a meaningful, methodological and technological aspects.

The article discusses the substantive aspect of the problem and offers some options for solving it: career guidance work with schoolchildren, conducting elective courses on the study of modern IT technologies, programming, robotics, encouraging the design activities of IT-oriented schoolchildren, etc.

It is proposed to use open educational resources (OER), issued with free licenses such as Creative Commons, as a methodological and technological basis for training. The advantages of OER in connection with the solution of the problem are discussed. It is proposed to use a cloud-based LMS such as Google Classroom (Google Suite for Education) as a hosting platform.

It is concluded that the involvement of school teachers in the preparation of potential (future) cadres of the digital economy is possible on the basis of the approaches proposed in the article.

En este artículo se presenta un estudio comparado de la Educación Física en lo relativo a la legislación, su estructura, el currículo, las escuelas y el profesorado, todo ello en países dentro del marco que compone la Red Euroamericana de Actividad Física, Educación y Salud (REAFES), con la característica de ser todos iberoamericanos y no anglófonos. Para ello, se elaboró un cuestionario de respuestas abiertas siguiendo los indicadores para una enseñanza de calidad para la Educación Física (EF)establecidos por la UNESCO a partir del análisis de los resultados de la aplicación de la Encuesta Mundial sobre la situación de la Educación Física (North Western Countries Physical Education Association, 2014). Se envía a expertos en el ámbito de los países implicados, recibiendo la respuesta de Colombia, Chile, España, Portugal, República Dominicana y Venezuela. Se analizan las encuestas comparando cada variable en cada uno de los países para poder obtener un abordaje de mayor profundidad que si analizáramos país por país. Se destaca la idea de que en todos los países analizados está garantizado (excepto excepciones coyunturales dentro de cada uno), una estructura, un currículo y una cualificación docente que asegura de forma suficiente los mínimos requeridos para el desarrollo de una Educación Física de calidad y, por el contrario, es a la hora de establecer programas fuera del horario lectivo (educación formal), donde se encuentran mayores diferencias en las intenciones y riquezas de los programas de actividades fuera de estos horarios (educación informal y no formal).

Inequalities in middle-income Europe and Central Asia: A tale of three studies
Authors: Slay Ben , Anvarova Tahmina
Published: December 2019

This paper focuses on how questions of inequalities in middle-income countries in Europe and Central Asia are dealt with in three recent studies: the EBRD’s “Transition Report 2016–17”; the World Bank’s 2018 study “Toward a new social contract: Taking on distributional tensions in Europe and Central Asia”; and UNDP’s “Regional human development report 2016. Progress at risk: Inequalities and human development in Eastern Europe, Turkey, and Central Asia.” While the three studies differ in terms of objectives, conceptual frameworks, country coverage, data and indicators, and policy recommendations, they also share important commonalities — particularly in terms of creating “regional” inequality narratives for transition economies, reconciling official data with common perceptions of inequalities in the region; improving data quality, quantity and availability, and changes in tax and social policies.
Dificultades en el Aprendizaje de la Función Definida por Tramos: una mirada desde el enfoque instrumental de Pierre Rabardel
Authors: Chumpitaz Malpartida Luis Daniel
Published: December 2019

Luego del diseño y validación de una secuencia de aprendizaje, se llevó a cabo una experiencia de aprendizaje con  estudiantes de las carreras de Ingeniería en la Universidad San Ignacio de Loyola. Para ello, los estudiantes identificaron elementos como dominio, rango e intervalos de monotonía; representaron la gráfica en un plano cartesiano; determinaron la regla de correspondencia, y realizaron transformaciones a las gráficas de las funciones definidas por tramos presentadas en las actividades de esta secuencia. Se realizó un estudio de las dificultades en el aprendizaje de la Función Definida por Tramos, debido a que es válido afirmar que, si existe la posibilidad de reducir dificultades, esto podría, a su vez, minimizar las dificultades en el aprendizaje de nuevos conocimientos del Cálculo, como los conceptos en la teoría de límites y continuidad, y en particular, en funciones cuyas gráficas no pueden ser realizadas con un solo trazo. Para identificar estas dificultades en las acciones de los estudiantes, estudiamos la Función Definida por Tramos como un objeto semiótico desde el enfoque instrumental desarrollado por Rabardel (1995). En el análisis de las interacciones de los estudiantes con la Función Definida por Tramos, se identificó que los estudiantes movilizaron esquemas de uso preexistentes que permitieron minimizar las dificultades en la secuencia de aprendizaje. También se pudo observar en las últimas actividades que algunas propiedades de este artefacto conservaron las funciones adquiridas durante su transformación a instrumento.

PENINGKATAN PRODUKTIVITAS PADI LAHAN RAWA LEBAK MELALUI PENGGUNAAN VARIETAS UNGGUL PADI RAWA
Authors: Helmi
Published: December 2019

In 2014 the total area of rice fields in North Sumatra was 464 827 ha, which has a land area of irrigated rice 291 062 ha, while the non-irrigated rice land area of 173 765 ha. Non irrigated wetland is classified into three agro-climatic types include 1). Rainfed areas, 2). Tidal wetland and 3). Lowland swamp wetland or non-tidal swamp. The potential development of swamp wetlands for paddy is still open because of the productivity is still low. Causes of low productivity such as soil fertility are relatively low, it still uses the old local varieties in 5-6 months, varieties that have been hereditary, and land management is still relatively conventional. Through the Integrated Crop Resource Management approach (PTT), swamp wetlands have the potential to be developed and are expected to become a contributor to rice production significantly. The aim of this research is to provide the technology package for lowland swamp rice cultivation in North Labuhan Batu Regency, North Sumatra Province. The research was conducted in the village of Sidua-Two, Sub District of South Kualuh, North Labuhan Batu district, from April to September 2014. Research using randomized block design (RBD) with 7 treatment swamp rice varieties that Inpara1, Inpara2, Inpara3, Inpara4, Inpara5, Margasari and varieties that farmers commonly planted the Mekong. Treatments were replicated three times, cooperator farmers used as replication with a plot area of 20m x 25m with a total area of 1ha. The results showed that the varieties Inpara1, Inpara2, and Inpara 3 provide the highest productivity compared to other varieties. Additionally varieties Mekongga still gave good productivity in lowland swamp. The main obstacle a lowland swamp land development is waterlogging, and unpredictable drought, depending on the circumstances of hydro topography, rainfall, and water level of local rivers. Results of soil analysis showed the content of micro-nutrients such as Al, Fe, Mn, Band Sare also included a higher category. The high content of elements Al and Fe cause soil reactions that are highly acidic soil and the soil pH is very low. Recommendations on a package of rice cultivation in shallow lowland swamp land need to be implemented in order to increase the productivity of lowland swampland.

The Inceptisols is a soil in great amount and widely distributed in Indonesia, even in the province of Aceh Inceptisols is the most extensive amount. The Inceptisols were found from lowland up to highland, and their properties are very varied. Commonly, the soil fertility of the Inceptisols of lowland is low. Calcite and Organic Matter are the easy matter found, and to be considered as a better soil amendment. While maize is improved varieties of crops that its production constantly to be increased. This experiment was conducted in order to study the contribution of organic matter as well as calcite contribution to the change of iron and manganese in soil and uptake by maize at North Aceh Inceptisol. Kinds of organic matter that was used consist of cow manure and water hyacinth (60:40). The fully randomized design has been conducted that consists of two combined treatment factors with three replicated. The factor is related to the kinds of organic matter was 0.0, 2.0, 3.0 and 4.0 ton ha-1 and calcite was 0.0, 1.0 and 1.5 ton ha-1. The results showed that the application of organic matter and calcite significantly affect levels of iron and manganese in the soil and plants. Dose organic material 4 ton ha-1 and calcite 1.5 tons ha-1 are able to increase at the highest level of the iron content of the soil, while the dose of organic materials 4 ton ha-1 and calcite dose 0.0-1.0 tonnes ha-1 is the best for the increasing of manganese in the soil. The highest content of iron and manganese of maize crop was obtained at a dose of 6.0 tons ha-1 of organic matter without calcite application.

Salinitas menjadi salah satu ancaman bagi sistem produksi bahan pangan, termasuk kedelai. Salah satu strategi untuk mengatasi dan mengeliminasi penurunan produksi kedelai akibat meluasnya salinitas adalah merakit varietas toleran salinitas melalui persilangan. Seleksi merupakan tahap yang sangat menentukan keberhasilan tujuan pemulia dalam perakitan varietas unggul, dimana progeni yang terpilih berdasarkan mekanisme toleransi selanjutnya akan digunakan dalam perakitan varietas kedelai tahan salinitas dan berdaya hasil tinggi.Tujuan dari penelitian ini untuk menduga pewarisan genetik karakter morfologi hasil persilangan F2 tanaman kedelai pada cekaman salinitas. Penelitian dilaksanakan di Rumah kasa kebun percobaan Fakultas Pertanian Universitas Sumatera Utara, pada bulan Februari 2015 sampai dengan November 2015. Benih yang digunakan pada penelitian ini adalah seluruh benih F2 kedelai dari dua hasil persilangan, Varietas Anjasmoro (A) dan Grobogan (G) sebagai tetua betina dan varietas Grobogan yang telah mengalami beberapa tahap seleksi teruji tahan salin sebagai tetua jantan (N1, N2, N3, N4, N5) sehingga didapatkan 9 kombinasi genotipe hasil persilangan yaitu: AxN1, AxN3, AxN4, AxN5, GxN1, GxN2, GxN3, GxN4, GxN5 selanjutnya benih F2 tetua Anjasmoro, Grobogan, dan tetua N.

Pertanian tumpangsari merupakan pola penanaman dua atau lebih tanaman yaitu tanaman semusim dan tanaman tahunan yang bertujuan dapat menekan populasi hama. Salah satu cara menekan populasi hama adalah dengan menggunakan musuh alami yang sebagian besar berasal dari Arthropoda. Terkait dengan hal tersebut dilakukan penelitian dengan tujuan untuk mengetahui: (1) indeks keanekaragaman, kemerataan, dan kekayaan Arthropoda pada lahan pertanian tumpangsari di Kecamatan Bumiaji Kota Batu; (2) jenis Arthropoda yang berpotensi sebagai predator pada lahan pertanian tumpangsari di Kecamatan Bumiaji Kota Batu; dan (3) ada tidaknya hubungan kondisi faktor abiotik dengan jumlah spesies Arthropoda di Kecamatan Bumiaji Kota Batu. Pengambilan Arthropoda dilakukan pada lahan pertanian tumpangsari brokoli umur 4 minggu dan apel yang sedang berbunga dengan metode pitfall trap untuk pengambilan Arthropoda yang aktif di permukaan tanah dan jaring serangga untuk pengambilan Arthropoda yang aktif ditajuk tumbuhan. Penelitian dilakukan pada bulan Agustus hingga September 2013. Analisis yang digunakan dalam penelitiaan ini yaitu menggunakan indeks keanekaragaman, kemerataan, dan kekayaaan; sedangkan analisis hubungan faktor abiotik dengan jumlah spesies menggunakan regresi linier berganda. Hasil penelitian ditemukan jenis Arthropoda yang teridentifikasi sebagai predator sebanyak 19 spesies, Nilai indeks keanekaragaman sebesar 2,73 yang termasuk dalam kategori sedang; indeks kemerataan sebesar 0,82 yang mendekati nilai 1 yang berarti memiliki kemerataan yang merata dan kondisi stabil; dan indeks kekayaan sebesar 4,72, ada hubungan antara faktor abiotik dengan jumlah spesies Arthropoda predator yaitu pada taraf signifikan R2 total sebesar 20,3% dan yang paling berpengaruh adalah suhu tanah dan kecepatan angin. Perlu dilakukan uji laboratorium Arthropoda predator hama pada tanaman brokoli dan tanaman apel.
