Authors: Messias Nayane Keilla , Martins Mário Henrique da Mata , Castro Cássia Bezerra de
Published: April 2020

O estudo analisa versões de usuários de serviços de saúde mental sobre a internação psiquiátrica involuntária. Para alcançar esse objetivo, faz uma revisão crítica da literatura em base de dados especializada, observação do cotidiano de instituições de atendimento a pessoas com transtorno mental que passaram ou se encontram em situação de internação psiquiátrica involuntária e entrevistas semiestruturadas com essas pessoas. A análise se pauta no princípio genealógico e no conceito de versões. Os resultados mostram que os estudos em saúde mental tem privilegiado o discurso de autores e profissionais da rede de saúde sobre o assunto em detrimento dos usuários. Nas entrevistas que realizamos, os usuários denunciam práticas manicomiais geradoras de exclusão e violação de direitos, seja nos serviços psiquiátrico-hospitalares ou nos de atenção psicossocial. Conclui-se pela necessidade de retomar o discurso dos usuários nos estudos científicos e no cotidiano dos serviços para orientar práticas em saúde mental.

Published: April 2020

Objetivo: Apresentar a prevalência de (in)segurança alimentar e nutricional e analisar a associação desta com alguns indicadores socioeconômicos e o perfil antropométrico das mulheres beneficiadas por programa social. Metodologia: A população do estudo foi constituída por mulheres beneficiadas pelo programa Minha Casa Minha Vida, no Município de Petrolina-PE. Foram coletadas informações sobre os indicadores socioeconômicos, como raça, escolaridade, renda, quantidade de moradores. Foram aferidos o peso (Kg) e a altura para o cálculo do IMC. Por fim, foram coletadas as informações sobre (in)segurança alimentar por meio da Escala Brasileira de Insegurança Alimentar (EBIA). Resultados: A amostra do estudo foi constituída por 206 mulheres, em que 23,3% de suas famílias investigadas apresentaram segurança alimentar. O restante apresentou insegurança alimentar, 53,4% apresentaram insegurança leve, 13,6% insegurança moderada e 9,7% insegurança alimentar grave. O perfil antropométrico dessas mulheres não mostrou associação com a (in)segurança alimentar, sendo que 3,4% encontraram-se com baixo peso, 44,2% encontraram-se eutróficas e 52,4% apresentaram sobrepeso ou obesidade. Os indicadores socioeconômicos associados foram a renda total do domicílio, a escolaridade e a raça, enquanto a quantidade de moradores não se associou. A maior parte das mulheres eram pardas ou negras, possuíam baixa escolaridade e um rendimento domiciliar de até 1 salário mínimo, com quatro ou cinco moradores em seu domicílio. Conclusão: A população beneficiada apresenta elevado índice de insegurança alimentar, que está associada à baixa qualidade vida. Dessa forma, programas precisam sejam reformulados para garantir aos brasileiros acesso as necessidades básicas que possam assegurar bem-estar e qualidade vida.

Identificación de Helicobacter pylori por medio de la coloración especial de Warthin-Starry en biopsias de pacientes con gastritis crónica folicular, previamente negativas en la tinción de hematoxilina-eosina
Authors: Ahumada Rodríguez Enoc , Rodríguez García Marcela , Hidalgo Piedrahíta Estefanny Johanna , Ahumada Duque Juliana , Castro John Fredy
Published: April 2020

Las técnicas empleadas para la detección del Helicobacter pylori (H. pylori) son no invasivas e invasivas. En estas últimas, la presencia del H. pylori se determina a partir de la tinción de hematoxilina-eosina (HE), prueba rutinaria, mientras que en pocas ocasiones se aplica la tinción de Warthin-Starry (WS) como coloración especial.
Objetivo: identificar la presencia de H. pylori por medio de la coloración especial de la WS en biopsias de pacientes con gastritis crónica folicular, previamente negativas en la tinción HE.
Materiales y métodos: se desarrolló un estudio de tipo descriptivo transversal, en un período de 12 meses. Se tomaron los bloques de parafina de las muestras de la mucosa gástrica de pacientes con diagnóstico de gastritis crónica e hiperplasia folicular. Además, se extrajo un corte histológico del mismo bloque, al cual se le aplicó HE y se determinó la presencia o ausencia de H. pylori. Así, de estar ausente, se tomó del mismo bloque un corte adicional y se aplicó WS. Esto se evaluó con el fin de identificar la existencia o no del bacilo.
Resultados: se recolectaron 314 muestras; 209 fueron negativas y 105 fueron positivas para HE. El 45 % (94) de estas muestras fueron positivas respecto a la presencia del bacilo, al aplicar la segunda coloración, y el 55 % (115) de las muestras persistieron negativas.
Conclusión: el hallazgo de H. pylori es significativamente alto al aplicar la coloración de WS a muestras cuyo estudio histológico evidenció la ausencia del bacilo en biopsias de la mucosa gástrica, especialmente en muestras con escasa cantidad de bacterias.
Evaluación del dolor y distensión abdominal según agente insuflante (CO₂ versus aire) en una unidad de endoscopia digestiva avanzada en Manizales, Colombia.
Authors: Caicedo Carlos Andrés , Arango Molano Lázaro Antonio
Published: April 2020

Objetivo: comparar la magnitud del dolor y el perímetro abdominal; la incidencia del dolor y la distensión abdominal, y las complicaciones según el agente insuflante utilizado.

Pacientes y método: estudio prospectivo analítico de cohorte. Se recolectaron datos de 43 colangiopancreatografías retrógradas endoscópicas (CPRE) y 20 colonoscopias insufladas con dióxido de carbono (CO2); para cada una se buscó un examen control con aire ambiente. En total, se sumaron 86 CPRE y 40 colonoscopias. Además, se realizó una caracterización clínica, un análisis bivariado y multivariado.

Resultados: el procedimiento más doloroso fue la colonoscopia; sin embargo, el 60 % de los pacientes de colonoscopia, y el 70 % de aquellos de CPRE, no presentaron dolor 15 minutos después de haber despertado luego del examen. Asimismo, no se hallaron diferencias estadísticamente significativas según la indicación del examen, la presencia o intensidad de dolor al momento del procedimiento, la edad, el sexo o el diagnóstico. El riesgo relativo (RR) de dolor inmediato fue 4,8 veces superior, cuando la insuflación se realizó con aire en vez de CO2 (RR = 4,8; intervalo de confianza [IC], 95 %: 2,3 a 9,2; p <0,001). Entre tanto, el riesgo de distensión abdominal en el grupo con aire fue 2,6 veces superior, en comparación con el grupo insuflado con CO2 (RR = 2,6; IC, 95 %: 1,8 a 3,9; p <0,001). El CO2 redujo la probabilidad y la magnitud de la distensión abdominal y del dolor inmediatos, posteriores a la colonoscopia o a la CPRE. No hubo complicaciones en ninguno de los 126 pacientes.

Conclusiones: el dolor y la distensión abdominal se presentan con menor frecuencia e intensidad cuando se usa CO2 como agente insuflante. Ninguno de los procedimientos presentó complicaciones mayores.
Prevalencia y características histológicas de los pólipos diminutos del recto y del sigmoides en una población colombiana
Authors: Parga Julián , Otero Regino William , Gómez Zuleta Martín Alonso
Published: April 2020

Introducción: el cáncer de colon y recto (CCR) se origina a partir de pólipos adenomatosos y serrados. Por tanto, se recomienda que todos los pólipos colónicos sean resecados y enviados a patología. Sin embargo, en los pólipos diminutos (<5 mm) del recto y del sigmoides existe controversia sobre esta conducta, razón por la cual se ha planteado la estrategia de resecar y descartar o dejar in situ, a partir de la utilización de endoscopios avanzados (con una imagen de banda angosta [Narrow Band Imaging, NBI] u otras), y se logre concordancia con la histopatología, superior al 90 %. En nuestro medio, no hay estudios prospectivos con luz blanca sobre la prevalencia y las características histológicas de estos pólipos en el recto y el sigmoides. Por esta razón, se desarrolló este trabajo. Materiales y métodos: estudio de prevalencia analítica, prospectivo. Se incluyeron las colonoscopias de tamización realizadas en la Unidad de Gastroenterología de la Clínica Fundadores de Bogotá, entre enero y julio de 2018. Resultados: se incluyeron 719 pacientes. La prevalencia de pólipos diminutos en el recto y el sigmoides fue del 27 % (intervalo de confianza [IC], 95 %: 23,7-30,2 %). El 50 % eran pólipos adenomatosos, mientras que en 8 casos se presentó una displasia de alto grado (DAG). Entre los pólipos diminutos, 3 fueron tumores neuroendocrinos. No hubo cáncer en ninguna de las lesiones. Conclusiones: la mitad de los pólipos diminutos encontrados fueron adenomatosos y 8 (0,83 %) tuvieron DAG. Recomendamos resecar todos los pólipos diminutos hasta que los estudios locales realizados con NBI u otra tecnología demostrasen la capacidad para discriminar en más del 90 % los pólipos hiperplásicos (dejarlos in situ) o adenomatosos (resecarlos).
Colitis eosinofílica, un diagnóstico poco sospechado
Authors: Prieto Ortíz Robin Germán , Prieto Ortíz Jhon Edison
Published: April 2020

La enfermedad gastrointestinal eosinofílica (EGIE) agrupa diversas patologías que pueden comprometer el tracto gastrointestinal. La más conocida de ellas es la esofagitis eosinofílica, mientras que la menos distinguida es la colitis eosinofílica (CE), que fue informada por primera vez en la literatura de 1959.
La CE se caracteriza por la existencia de trastornos funcionales digestivos y la diarrea se constituye en el más importante de estos. Aunque no existen unos criterios diagnósticos claros, se considera que los pacientes deben presentar hemogramas con eosinofilia y hallazgos histológicos de infiltración eosinofílica, los cuales son determinados por el estudio histológico de las biopsias tomadas mediante la colonoscopia.
Así pues, la CE afecta especialmente a neonatos y adultos jóvenes, y se ha relacionado con causas genéticas y alérgicas. El tratamiento inicial consiste en la suspensión de los alérgenos. Dentro del arsenal farmacológico, se emplea la prednisolona, así como medicamentos entre los que se incluyen la budesonida y los inmunomoduladores en los casos refractarios, con lo cual se logra una adecuada respuesta. Presentamos una actualización de este tema.
Modernizacija urbanoga života u Hrvatskoj kroz prizmu stambenih i komunalnih politika u razdoblju socijalizma
Authors: Bara Mario
Published: April 2020

U članku se upućuje na važnost nekih aspekata polustoljetne modernizacije u Hrvatskoj (1945. – 1990.) koja je donijela industrijsku transformaciju države i promjenu strukture stanovništva. Cilj je pokazati utjecaj javnih politika, tj. racionalizacije odlučivanja na primjerima modernizacijskih procesa u stambenim i komunalnim politikama.
Paternalistička uloga države s jasnim nedostatkom pluralnosti bila je vidljiva u svakom segmentu gospodarskoga, političkoga i društvenoga života. Mjere za brzu gospodarsku i socijalnu transformaciju društva započele su još tijekom rata. Velike državne intervencije bile su naglašene u industrijalizaciji i urbanizaciji, koje su pratile migracije
radne snage iz ruralnih u urbana područja. Zbog velikoga broja novih stanovnika gradova vlasti su posvećivale veliku pozornost stambenim i komunalnim politikama. Istovremeno ovaj rad smjera upozoriti na segmente
političkoga odlučivanja koji do sada nisu bili promatrani kroz dimenziju javnih politika na primjeru nekih aspekata modernizacije urbanoga života u Hrvatskoj. U zaključku se upućuje na mogući interdisciplinarni okvir istraživanja problema javnih politika u povijesnoj dimenziji.

analytical procedures involved in working on it.
Combined effects of variable viscosity and thermophoretic transportation on mixed convection flow around the surface of a sphere
Authors: Abbas Amir , Ashraf Muhmmad
Published: April 2020

The physical behavior of the combined effect of temperature dependent viscosity and thermophoretic motion on mixed convection flow around the surface of a sphere is investigated. The set of non-linear coupled PDE is formulated and then non-dimensionalized by using an appropriate set of dimensionless variables. The dimensionless model is then transformed to convenient form for integration by employing a suitable set of primitive variables formulation and then discretized by using an efficient implicate finite difference scheme for numerical simulation. The effect of controlling parameters on velocity profile, temperature profile, and mass concentration as well as skin friction, rate of heat transfer, and mass transfer rate are analyzed. The obtained numerical results for different values of controlling parameters indicate that, velocity profile gains its largest magnitude at position X = 1.5 radian and slows down at postion X = ? radian. It is also predicted that the temperature distribution and mass concentration are diluted at position X = 1.5 radian due to rapid motion of fluid. The numerical results are highlighted in graphical as well as in tabular form.
A kinetic study of HKUST-1 for desulfurization applications
Authors: Al-Yassiry Ali , Al-Rubaye Rana
Published: April 2020

In this study, HKUST-1 prepared under solvothermal conditions and tested in desulphurization of model gasoline. The prepared HKUST-1 samples were characterized using surface area and pore volume analysis (BET), powder X-ray diffraction (XRD), and Fourier transforms infrared spectroscopy (FTIR). The prepared HKUST-1 was used for desulphurization of model gasoline (thiophene with iso-octane), and the influence of the thiophene concentration, HKUST-1 dose, temperature, and contact time. The experimental results revealed that the sulfur content in model fuel was reduced from 1500-148.2 ppm (90.12% removal efficiency) for four hours contact time at 30 ?C. In addition, an isotherm adsorption and kinetics study were performed for a batch process to understand the system equilibrium (i. e., the best fitting Langmuir isotherm or Freundlich isotherm). The kinetics study proved that the contained sulfur removal was best fitted by pseudo-second-order kinetics. Regeneration results show that the HKUST-1 has a reversible nature as an adsorbent. Therefore, HKUST-1 might be used as a promising adsorbent for removing thiophene compounds from gasoline.
Development and prioritization of renewable energy scenarios using SWOT-FANP methodology
Authors: Stojcetovic Bojan , Nikolic Djordje , Jevtic Miroljub , Jaksic Uros
Published: April 2020

The main goal of this paper is to develop and prioritize renewable energy scenarios for electricity production. The model proposed in the paper was applied on the example of the municipality of Strpce, enclave in south Kosovo**. The model consists out of three phases, and the decision-making and planning process involves a group of decision makers, i.e. selected experts and stakeholders. In the first phase, a group of decision makers, using a collaborative planning method and Homer pro software, defined eight renewable energy scenarios based on renewable energy potentials and electricity demand in Strpce. In the second phase, a group of decision makers, using the strengths, weaknesses, opportunities, and threats analysis, defined a total of 22 criteria to evaluate scenarios. Finally, in the third phase, a group of decision makers used fuzzy analytical network process methodology to prioritize scenarios. Results show that a scenario that includes installation of photovoltaic panels in Strpce households to cover 50% of the electricity demand is first ranked. The proposed model has a universal character which means that it can be applied in other municipalities/cities and regions. Also, the model enables collaborative planning through the inclusion of different stakeholders whose number and type can be adjusted according to the subject/area of research.
Solar-assisted CO2 capture with amine and ammonia-based chemical absorption：A comparative study
Authors: Wang Junyao , Liu Liangxu , Zeng Xuelan , Li Kaixiang
Published: April 2020

Intensive energy penalty caused by CO2 separation process is a critical obstacle for retrofitting power plant with carbon capture technology. Therefore, the concept of utilizing solar energy to assist solvent regeneration for post-combustion carbon capture power plant is proposed recently as a promising pathway to compensate the efficiency reduction derived from CO2 capture process. However, the feasibility of solar-assisted post-combustion technologies largely depends on the types of CO2 absorbent, categories of solar thermal collectors, areas of solar field, and the integration of thermal energy storage system. Therefore, this paper conducts a comparative analysis on monoethanolamine-based and NH3-based so-larassisted post-combustion power plants employing two types of solar collectors, i.e the vacuum tube and the parabolic through collector, with climate data of Tianjin City, China. Levelized costs of electricity and cost of CO2 removed are comparatively studied for both solar-assisted post-combustion configurations. Results show that the proposed solar-assisted post-combustion configurations are economically viable when the price of vacuum tube is lower than 86.64 $/m2 and 117.29 $/m2 for the monoethanolamine-based and NH3-based solar-assisted post-combustion power plant, respectively. Meanwhile, the price of parabolic through collector should be less than 111.12 $/m2 for the monoethanolamine-based and 114.51 $/m2 for the NH3-based solar-assisted post-combustion power plant. It is indicated that employing the vacuum tube for chilled NH3-based solar-assisted post-combustion power plant offers a promising approach to reduce the energy penalty with attractive economic performance.

Positioning students as game journalists: Transforming everyday experiences into professional discourse
Authors: Hanghøj Thorkild , Lützen Peter Heller , Geer Simone Lysholt
Published: April 2020

The aim of this paper is to present findings from a study which is part of an ongoing Design-Based Research project which explores how students can transform their everyday experiences with and attitudes towards games into game journalism within the context of Danish as a subject. Based on a theoretical framework combining domain theory with Ivanič’s theory of writing as identity construction, we analysed selected student articles and student interviews from four secondary classrooms (Grades 7–9). The findings show that some students mainly positioned themselves through a personal discourse, which was highly influenced by their positive, negative or ambivalent attitudes to their chosen game journalistic topics. Other students mainly positioned themselves through a professional journalistic discourse by means of critical reflection and representation of multiple perspectives on their topics. Based on the students’ high level of engagement in the writing process and the wide range of possible selves adopted by the student writers, we concluded that games and game culture represent a topic well-suited for transforming students’ everyday experiences and attitudes into journalistic texts.
Suppliers as Key Collaborators for Sustainable Tourism Development
Authors: Hjalager Anne-Mette
Published: April 2020

The purpose of this chapter is to introduce a conceptual approach to understanding driving forces for innovation in sustainable tourism development. The model underpins the fact that innovation in tourism is not solely the effect of a strategic and wilful internal action in tourism firms and organisations, but also the consequences of external driving forces. Further, the article offers a more detailed review of the importance of suppliers as (one of several) push factors for sustainable tourism development. Examples are provided, and possibilities and limitations in terms of a rapid development of more sustainable practices in tourism are discussed. A four-field model aims at stimulating the search for new forms of collaboration between tourism firms and their suppliers in the upstream supply chain, and it adds dimensions to the traditional perspectives on value chains in tourism.

Published: April 2020

Transformações tecnológicas e reflexos da globalização são agentes que modificam dinâmicas sociais e profissionais, (inter)agir em sociedade, especialmente, no mundo do trabalho são atuações reconstruídas ao longo do tempo. Aparecem, assim, novas demandas por perfis profissiográficos que respondam às transformações ocorridas. Reflete-se sobre o papel da educação superior e das perspectivas curriculares na formação desses futuros profissionais de distintas áreas. Ganham espaço nessa discussão, as metodologias ativas de aprendizagem que consideram o estudante o centro do processo de ensino e aprendizagem aproximando suas formações acadêmica e profissional. Inserido nesse contexto, este artigo objetiva compreender aspectos históricos e princípios de dois formatos de metodologias ativas de aprendizagem e sua implementação em contextos curriculares de educação superior no Brasil. Para tanto, são resgatados movimentos históricos de teorias e pressupostos que ajudaram na sistematização das seguintes metodologias ativas de aprendizagem: PBL (Problem Based Learning) e PLE (Project Led Education). São discutidos, à luz do que definem as Diretrizes Curriculares Nacionais, princípios e orientações dessas metodologias e analisados perfis e habilidades profissionais requeridas em Projetos Curriculares de Curso de dois contextos de educação superior brasileiros, cursos de Medicina e Engenharia, consideradas pioneiras na implementação da aprendizagem ativa. Os resultados sinalizam que movimentos históricos e princípios de metodologias ativas orientam novas propostas de desenhos curriculares na educação superior. Ambas instituições analisadas propõem inserir os estudantes na cultura de solução de problemas, enfatizando aspectos de autonomia diante de situações reais de sua profissão, formação técnico-científica com atitudes ético-humanísticas e a capacidade de trabalhar em equipes multidisciplinares.
A semiotic theory of self-control
Authors: Acosta López de Mesa Juliana
Published: April 2020

A presente proposta tem como seu principal objetivo mostrar como a emergência de hábitos autocontrolados de emoções podem ser explicados segundo a gramática especulativa de Peirce. Como resultado, espero mostrar, uma possível aplicação da gramática especulativa, sobre o qual muito é especulado, mas pouco é aplicado; segundo, sugerir uma possível teoria da linguagem entendida como uma forma controlada de nossos sentimentos de tal modo a permitir que sejam compartilhadas e comunicadas. Além disso, e ainda mais importante, isto mostraria que a divisão tradicional entre a faculdade da razão e a faculdade emocional não é tal, antes deve ser dito que a razão, ou melhor a razoabilidade, surge e afunda suas raízes nessa faculdade e cresce dela em um continuum. Assim, qualquer educação que vise o autocontrole deve começar com uma educação estética ou, se preferir, com uma educação sentimental.
Emotional, energetic, and entelic interpretants: epistemic and ethical pragmaticism in Ibri, Peirce, and Aristotle
Authors: Dilworth David
Published: April 2020

A semiótica ontológica de Peirce retomou o sentido de práxis racional de Aristóteles em seu sentido compartilhado da função de mediação do Interpretante lógico. O artigo está dividido em três partes. A primeira delineia a conceitualização de Ivo Assad Ibri da semiose de Peirce com relação à diferença entre o Interpretante emocional e o lógico, em especial com relação ao primeiro nos modos “degenerados” de fixação de crença e conduta; a segunda parte explica a conceitualização inicial de Peirce daquela doutrina em seu tratamento do “Homem-signo” em “Some Consequences of Four Incapacities” (1968); a terceira parte apresenta a Ética a Nicômaco de Aristóteles como a origem clássica da trajetória principal da semiose de Peirce, ao correlacionar o conceito de teleologia de desenvolvimento de Peirce com o conceito paralelo de caráter disposicional ativo de Aristóteles (hexis) energizado pela média ética (mesotes) como o interpretante pragmatista da conduta.
Cross-border cooperation on the EU-Russian borders: results of the program approach
Authors: Sebentsov Alexander B.
Published: April 2020

Cooperation across the Russia-EU border has been drawing much attention in recent years. The majority of studies point out programs’ efficacy, high density of border institutions and resistance to geopolitical risks among other factors. These advancements can be explained by the theory of multilevel collaboration which implies that diverse and multiple cooperation institutions can effectively distinguish matters of high politics from practical issues concerning interests of those living along the external borders.

The article aims to analyze the impact of cross-border cooperation programs (CBC Programs) on the thematic, institutional and spatial structure of the cross-border relations.

The research is grounded in the overview and analysis of a large volume of empirical data including reports and descriptions of cross-border cooperation programs, data provided by the regional governing agencies, as well as 76 semistructured interviews obtained from regional experts as part of several research expeditions by the Laboratory of Geopolitical Studies of the Institute of Geography RAS taken place over the period from 2011 to 2018.

Main characteristics and long-term trends of the cross-border program approach are examined as follows: growth in governmental coordination on various agency levels aimed at development and implementation of mutually beneficial partnerships, creation of joint program management bodies, development of uniform policies and joint funding sources for projects, and interest in maintaining an equal level of collaboration.

It is revealed that gradual rise of the programs’ role in cross-border cooperation in the area contributed to the restructuring of its institutional systems, launching selection process for the existing border institutions (euro-regions, crossborder regional councils, and others), as well as triggering the synergy effect among them and the transborder forms of cooperation.

The main characteristics of spatial partnership structures are identified. These include those consisting of high concentration of project activities taking place within large urban centers along the external borders and those asymmetrical to cross-border interactions. The former is especially pertinent to the Russian side of the border where just a small number of such centers are involved in up to 70-80% of project activities. Even fewer number of Russian cities initiate their own collaborative projects. A gradual spatial shift of cooperative projects toward the areas immediately proximate to the borders, as well as the decrease in asymmetry of transborder cooperation are identified as the new trends by the author.
Emerging and re-emerging natural focal diseases of European Russia (typological classification of nosological profiles and dynamics of incidence)
Authors: Malkhazova Svetlana M. , Pestina Polina V. , Tikunov Vladimir S.
Published: April 2020

This study considers an automated typological classification version by using the extensive factual material in analysis of emerging and re-emerging natural focal diseases of European Russia.

The typological classification of nosological profile (a set of diseases) and the incidence dynamics for five nosological forms (hemorrhagic fever with renal syndrome, ixodic tick-borne borreliosis, tick-borne encephalitis, tularemia, and leptospirosis) was created using the formal methods of mathematical-cartographical modeling. This classification of the incidence in 1997–2015 yielded five types of the nosological profiles. These types vary by years, which is associated with the dependence of the incidence on climatic conditions in each specific year and on extent of deratization and preventive measures. The results obtained can be used to forecast potential epidemiological outbreaks and to develop targeted and appropriate for each region measures.

Published: April 2020

This paper aimed to characterize urbostratozems (Urbic Technosol, WRB) of Saint Petersburg located in industrial (“Electrodepo” railway station) and residential (region Polish Garden) zones. These soils were also compared with background (natural) soddy podzol soil (Umbric Albic Gleic Podzol, WRB) sampled in recreational zone (suburban park “Oranienbaum”). Soil samples were collected from soil horizons for chemical analysis and from top of soils for microbialogical analysis in June of 2012. Chemical properties (pH, total organic carbon, mobile forms of K and P) and content of heavy metals (Pb, Cu, Zn, Ni) in soils were determined. Culturable forms of microorganisms (bacteria and fungi) were studied. Assessment of the enzymatic activity of the soil was carried out by culturing of microorganisms-producers of protease, amylase, cellulase and lipase on special media. Biotesting using cress (Lepidium sativum L.) seeds had been carried out for assessment of soil phytotoxicity. It was found that chemical properties of urban and natural soils differ greatly. Heavy metal pollution was evident in both urban soils, but maximum concentrations of heavy metals were found in the soil of the industrial zone. Phytotoxocity had been also most pronouncend in the soil of the industrial zone. The natural soil exhibited significantly higher respiration activity than urbostratozems. The greatest difference in the structure of the bacterial and fungal communities was observed between the natural soil of the recreational zone and the urbostratozem of the industrial zone. Algae had been present in the urban soils of the residential zone that was not observed in the natural podzol. The minimum number of producers of all enzymes, except for cellulase, was observed in the soddy podzol in the recreational zone. The maximum number of protease and amylase producers was found in the soil of the industrial zone. Lipolytic activity was almost the same in all samples. It was found that more sensitive biological methods are needed for environmental assessment of urban soils. The results of the article can be used by soil scientists and environmental engineers for a comprehensive environmental assessment of the condition of urban soils and for creating new urban green spaces.
Russian-Estonian border in the context of post-soviet ethnic transformations
Authors: Manakov Andrei G. , Kliimask Jaak
Published: April 2020

The authors explore the main trends and regional peculiarities of ethnic transformations during the post-Soviet period in the Russian and Estonian borderlands. Special emphasis is placed on the dynamics of the share of two dominant ethnic groups – Russians and Estonians. It is argued that the main trend of ethnic transformations is an increase of the share of the dominant ethnic groups in the structure of population. The almost Russian-speaking Ida-Viru county in Estonia is an exception, where together with a small growth in the share of Estonians, there was growth in the number of Russians. The authors analyse the dynamics of smaller Baltic-Finnic nations – Ingrians and Setus (Setos), living in the Russian border area with Estonia.
Coastal zones of modern Russia: delimitation, parametrization, identification of determinants and vectors of Eurasian dynamics
Authors: Druzhinin Alexander G. , Kuznetsova Tatyana Yu. , Mikhaylov Andrey S.
Published: April 2020

The resource potential of the oceans has historically had a fundamental impact on the development and spatial organization of mankind. The role of the «marine factor» in economic activity and the formation of settlement systems has increased even more in the modern period, including in Russia, which has long sea coasts that fulfill the country’s most important transport, communication, economic and resource, residential and military infrastructure functions. Since the mid2000s, in Russia there has been a steady increase in foreign trade activity and the marine economy. The author summarizes and develops theoretical concepts created in Russian science about the functions, boundaries, structure of coastal zones as special geographical areas. Based on GIS analysis and the study of a vast array of demographic and economic statistics, the coastal zone of post-Soviet Russia was delimited. Particular attention is paid to the innovative potential of coastal zones, the features of its localization and formation. It is shown that coastal zones and large cities act as a significant environment for building cross-border interactions in the scientific and innovative sphere. The author argues that a further «shift to the sea» of economic activity and the population of Russia is inevitable. It is provoked by geo-economic and geopolitical changes in modern Eurasia which include the processes of integration and disintegration in the Baltic, Black Sea basin, and the Caspian region, the intensification of geopolitical rivalry in the Arctic, and implementation of the Chinese initiative «One Belt - one Road». However, the development of the country’s coastal zones will be unstable, not universal and will be accompanied by a further concentration of socio-economic potential in the few leading coastal centers - St. Petersburg, Rostov-on-Don, Sochi, Vladivostok, Kaliningrad, Makhachkala, etc.
Beauty and personal care transnationalization: main changes in its spatial structure
Authors: Gladenkova Tatiana
Published: April 2020

At the turn of 21st century global beauty and personal care industry underwent dramatic changes in its territorial structure. The main factors of that changes were world economics institutional changes, primarily – the international trade liberalization, as well as the R&D progress. During abolition of tariffs or tariff cut the competition in beauty and personal care ratcheted up sharply. That was accompanied by sea changes in its macrogeography, particularly, by the manufacturing transnationalization (mainly, in the form of its «drift» to developing countries) and the general expansion of the range of countries specializing in the beauty and personal care production. The main drive-forces of beauty and personal care transnationalization and the resulting territorial changes in the industry are discussed.
Os Cursos On-line Abertos e Massivos (Mooc) como ambientes heutagógicos
Authors: Agonács Nikoletta , Matos João Filipe
Published: April 2020

Os Cursos On-line Abertos e Massivos, conhecidos como Mooc (Massive Open Online Course), são ambientes de aprendizagem únicos em virtude da grande dimensão e do alcance global de participantes. A criação de ambientes de aprendizagem para grandes públicos é extremamente complexa e levanta muitas  questões de desenho devido à diversidade da origem, da competência e das experiências prévias dos participantes. A teoria de aprendizagem emergente, a heutagogia, deve ser considerada quando se trata do desenho pedagógico de um Mooc. No entanto, o potencial dessa teoria no desenho desses cursos ainda não foi examinado profundamente. Este artigo tem como objetivo mapear a literatura dos dois campos de investigação envolvidos, nomeadamente na área dos Mooc e da heutagogia,  a fim de proporcionar uma compreensão extensa e profunda sobre o potencial da teoria heutagógica para o desenho de um Mooc. Os resultados desta análise indicam que existe um hiato entre o ambiente de aprendizagem do Mooc, que requer uma elevada autonomia por parte dos participantes, e as características do público-alvo que se revela despreparado para participar desse tipo de curso, aumentando a necessidade de entender melhor os aprendentes em termos de sua prontidão para aprender no ambiente Mooc.
