A obra de Hassis como sintoma do sujeito dialético, engedrando novas conexões fora de seu espaço e tempo
Authors: Palheta Cláudia Silvana Saldanha
Published: May 2019

ResumoPensando sobre a sobrevivência da imagem, o artigo propõe a análise da obra “Vento sul com chuva” (1957), de Hassis (1926-2001), artista catarinense, a partir das articulações engendradas por ela. Buscou-se as contribuições de Didi-Huberman e Walter Benjamin no intuito de se compreender as imagens como sintomas de uma memória que é particular e historicamente construída, constelando a obra com outras duas de expressiva simbologia: a fotografia do paraense Luiz Braga e o desenho de catarinense Susano Correia. O modo de estar e perceber o mundo, influenciaram, sobremaneira, a trajetória artística de Hassis, que passou a vida organizando e reorganizando imensurável arquivo de suas obras; objetos e documentos (hoje preservados pelo Instituto Hassis), que só tem significado se entendermos sua obra, enquanto imagem, como sintoma da relação dialética do próprio artista em seu espaço e tempo.AbstractThinking about the survival of the image, the article proposes the analysis of the work “South Wind with Rain” (1957), by Hassis (1926-2001), a Santa Catarina artist, based on the articulations engendered by it. The contributions of Didi-Huberman and Walter Benjamin were sought in order to understand the images as symptoms of a memory that is particular and historically constructed, constellating the work with two others of expressive symbology: the photograph of the Paraense Luiz Braga and with the drawing by Susano Correia, artist from Santa Catarina.The way of being and perceiving the world, influenced, the artistic trajectory of Hassis, who spent his life organizing and reorganizing the archive of his works; objects and documents (now preserved by the Hassis Institute), which is meaningful only if we understand his work as an image, as a symptom of the artist’s dialectic relation in space and time.
O discurso comunista no construtivismo russo: a arte a serviço da propaganda ideológica
Authors: Almeida João Flávio de , Kettelhut André
Published: May 2019

ResumoIdeologia é uma palavra que serviu de matéria-prima para teóricos de muitas áreas do conhecimento, principalmente nas ciências humanas. Dentro dessas ciências, o filósofo francês Michel Pêcheux ajudou a desenvolver, foi membro do círculo, e também maior expoente do método chamado Análise do Discurso. Ele afirmava que é na ideologia que o indivíduo se torna sujeito; mas é na ideologia também que os discursos são (re)produzidos historicamente, fazendo o sentido parecer autêntico e verdadeiro. A partir dessa concepção de ideologia que nos propomos a olhar o movimento artístico construtivista russo, usado interpelar sujeitos pela máquina de propaganda do regime comunista soviético.AbstractIdeology is a word that served as raw material for theorists of many areas of knowledge, especially in the humanities. Within these sciences, the French philosopher Michel Pêcheux helped to develop, was member of the circle, and also greater exponent of the method called Discourse Analysis. He affirmed that it is in ideology that the individual becomes subject; but it is also in ideology that discourses are (re) produced historically, making sense to appear authentic and true. From this conception of ideology we set out to look at the Russian constructivist artistic movement, used to question subjects by the propaganda machine of the Soviet communist regime.
Novel probes for selective fluorometric sensing of Fe(II) and Fe(III) based on BODIPY dyes
Authors: ŞENKUYTU Elif , OKUTAN Elif
Published: May 2019

Two novel
boron-dipyrromethene (BODIPY) based fluorescence turn-off sensors, which
demonstrate high selectivity and sensitivity toward Fe2+ and Fe3+
ions have been reported. A simple and high yielded synthesis of
fluorescent BODIPY derivatives with malonyl unit for sensitization have been
described. This approach provides quick, high yielded and low-cost preparation
of probes. The two sensors have been comprised of combination of one and two
BODIPY fluorophore and a malonyl unit, substituted on meso position of BODIPYs.
Synthesized BODIPY derivatives have been characterized via elemental analyses,
mass spectrometry, 1H and 13C spectroscopy and their
photophyisical properties were investigated by UV- Vis absorption and
fluorescence emission spectroscopy.  The
synthesized sensors (2, 3) have been
used as a fluorescent probe towards the selective and sensitive detection of
biologically important Fe2+ and Fe3+ ions in
tetrahydrofuran by fluorescence spectroscopy. The limit of detection (LOD) have
been calculated to be for the BODIPY 2,
14.61 (Fe2+), 1.22 (Fe3+) and for BODIPY 3, 1.16 (Fe2+) and 1.06 (Fe3+).

The development of quantitative digital phenotyping methods for evaluation of wild potato (section Petota Dumort., genus Solanum L.) tuberization is required for annotation of genebank collections and selection of the suitable donor material for potato breeding. There are no available methods specifically designed for the quantitative analysis of wild potato tuber morphology. The current study is devoted to evaluation of wild potato tubers’ morphological characteristics using a digital image processing technique. For this purpose, the mobile application SeedSounter developed previously for grain analysis was specifically adapted for tuber phenotyping. The application estimates the number and shape of objects scattered on a standard sheet of white paper (i. e. A3 or A4). Twelve accessions from the VIR genebank collection belonging to nine Petota species were grown in pots protected with garden fabric during the growing season of cultivated potato (Novosibirsk region). Tubers were collected form plants of nine genotypes. Three genotypes did not produce tubers. The weight of tubers collected from each plant was measured. The tuber yield from each plant was analyzed using SeedCounter (http://wheatdb.org/seedcounter). The number of tubers per plant was counted; the following characteristics were extracted from the images of individual tubers: length, width, projected area, length to width ratio, сircularity, roundness, rugosity and solidity. One-way ANOVA showed a significant effect of genotype on all measured characteristics. A pairwise comparison of nine Petota accessions using all measured parameters revealed statistically significant differences between 86 % of pairs. The overall tuber yield volume for each plant was  calculated as a sum of volumes of individual tubers; tuber volume was calculated from its length to width ratio and projected area. A strong correlation between the evaluated tuber yield volume and yield weight was shown. We propose tuber yield volume as a characteristic for a general evaluation of tuberization for wild potato, implementing the four-step scale from 0 to 3. According to this characteristic, the twelve wild potato accessions studied could be divided into four groups with different tuberization abilities. The evaluated tuberization ability is partially in accordance with previously obtained VIR data. The results presented demonstrate the possibility to use SeedCounter for  wild potato  collections phenotyping.

Logos i metanoia
Authors: Maryniak Bogusław
Published: May 2019

Celem artykułu jest rozważenie znaczenia dwóch tytułowych pojęć, które można znaleźć u podstaw myśli europejskiej. Nawiązując do pracy Giovanniego Reale, włoskiego historyka filozofii przełomu dwudziestego i dwudziestego pierwszego wieku, autor dokonuje próby rekonstrukcji greckiej refleksji o przemianie duchowej. Zaczynając od Odysei Homera i wybranych dzieł Platona, dokonana zostaje prezentacja „drugiego żeglowania”. W przypadku Platona szczególnie ważną rolę odgrywają Listy, wyraźnie prezentujące to pojęcie. Następnie zostaje omówiona przemiana tego pojęcia w neoplatonizmie Filona z Aleksandrii i Plotyna. Ponadto autor przypomina dwa greckie pojęcia czasu: Kronosa i Kairosa. Prowadzi to do odniesień wziętych ze współczesnej filozofii i literatury. Z jednej strony „drugie żeglowanie” nabiera nowego znaczenia w świetle koncepcji strumienia świadomości Wiliama Jamesa. Z drugiej zaś strumień świadomości został świadomie zastosowany w Ulissesie Jamesa Joyce’a do opisu sytuacji, w której nie dochodzi do „drugiego żeglowania”. W ten oto sposób na nowo może być reinterpretowana historia duchowej przemiany Odysa i Stefana Dedalusa z Ulissesa Jamesa Joyce’a.

Introduction. In the structure of the population prevalence in the Russian Federation, oncological diseases take the second place that defines the priority of the improvement of the consideration and adjustment of risk factors within the existing system of sanitary inspection. Material and methods. There was made the analysis of the radiation exposure to the population of the Rostov region by results of radiative and hygienic certification of the territory and by results of social-hygienic monitoring of population health in connection with environmental factors for the period 2006-2016. The subject of the analysis was the levels of the cancer prevalence and cancer mortality in the Rostov region and carcinogenic risks in comparison with the relevant priority factors. Results. More than 80% of the total equivalent dose received by each resident of the Rostov region depends on technogenic changed natural radiation. The most regulable natural factor is the content of radon in the soil of the sites allocated under the construction and also volume activities of radon in the air of residential and public buildings. The existing normative base considering all these components and therefore further essential change of accounting of a dose load of the population from the natural investment is problematic. At the same time, more than 99% of radiation exposure to the population from technogenic sources depends on medical radiation. By comparison of the actual cancer morbidity of the population with the calculated one, it is established that only 16.75% are caused by those factors which are quantitatively considered in the system of social-hygienic monitoring. Discussion. Medical radiation doesn't appear in the list of priority oncogenic factors and the radiative risk from medical radiation isn't distinguished in the system of social and hygienic monitoring in spite of the fact that it is provided in "The radiative and hygienic passport" of both territories, and the Russian Federation in general. Smoking as the main known reason for the cancer morbidity still presents in the list of risk factors. The radiation factor does not figure at all among the priority risk factors in the system of social and hygienic monitoring, and as a result, the components of radiation risk are not deciphered. Conclusion. The measures of the optimization of the consideration of carcinogenic risks in the system of social-hygienic monitoring concerning the differentiated calculation of risks from radiative factors and including information on smoking of the population in the statistical forms provided by institutions of medical service of the a primary link are proposed.

The article reflects methodological approaches to the construction of a priori models for assessing the occupational risk of medical workers in physiotherapeutic departments of sanatoriums under the influence of a complex of negative factors of the production environment. The authors carried out a comprehensive hygienic assessment of the occupational risk of medical personnel with the combined use of physiotherapeutic procedures in one of the sanatoria and resort institutions of the Altai Territory. The main objectives of the study were to measure physical, radiation and chemical factors in the work environment at workplaces of medical personnel and to calculate the degree of the occupational risk of workers in accordance with a priori risk assessment models. Based on the results of measurements of physical factors at workplaces of medical workers of physiotherapeutic departments, it is possible to conclude that complex harmful effects include inadequate levels of the air temperature in the work area, artificial illumination, air ionic composition of air and electromagnetic fields. The calculated risk was 0.0975, which corresponds to a moderate risk. The obtained results testify to the existence of a risk, the level of which cannot be neglected, despite the compliance of the level of impact with normative documents. The results of studies of the radiation factor at workplaces in the radon therapy department indicate the equivalent equilibrium radon volume activity to range from 25-109 Bq/m³,and the ambient dose equivalent of gamma radiation in the range of 0.15-0.18 μSv/h, which corresponds to hygienic standards. Therefore, the use of risk-oriented models seems reasonable even in working conditions that are not harmful or dangerous according to the criteria for a special assessment of working conditions. The leading role of electromagnetic radiation for this category of workers is proved in the course of calculations using risk-oriented models of professional risk assessment. It is proposed to develop measures to reduce the electromagnetic load, taking into account the medium and short-term outlook, with an annual review of the degree of occupational risk.

Introduction. Oncological pathology has a high medical and social significance, so it is important to study the conditions of its formation. The aim of the study was to evaluate the cumulative carcinogenic risk for the population of the administrative center of the Republic of Buryatia (Ulan-Ude). Material and methods. The identification of the carcinogenic hazard caused by the entry of chemical ingredients into the ambient air was carried out in 2005-2015. The exposure assessment is based on long-term average annual concentrations of carcinogens in the air, drinking water, food. Indices of comparative carcinogenic hazard (HCR) and individual carcinogenic risk (ICR) are calculated. Results. The huge engineering enterprises are sources of several substances with carcinogenic effects (formaldehyde, chrome VI, cadmium, niсkel, epichlorohydrin, etc.).The individual carcinogenic risk for residents of Ulan-Ude is included in the range unacceptable for the general population. The main pathway for chemical agents to enter the body is inhalation (79%). The greatest contribution to the total individual carcinogenic risk on admission from the air was made by formaldehyde, chromium VI and Benz(a)pyrene. Priority carcinogens coming from drinking water and food are arsenic, cadmium, lead. Conclusion. Results of the assessment of individual carcinogenic risk in Ulan-Ude indicate an unacceptable level of the impact on the population. The assessment has a number of uncertainties, which determines the need to further improve the monitoring system for carcinogenic hazards.

Published: May 2019

Introduction. The modern educational process is characterized by an increase in the educational load, the use of teaching aids, which are not provided for in the regulatory and methodological documents. Violation of the hygienic principles of organizing the education of children at school is the basis for the development of somatic pathology. The aim of the study: hygienic assessment of the educational process in schools with various training programs. Materials and methods. The subject of the research is the organization of the educational process of the first, second and third levels of education in schools with in-depth study of the subjects of the physical and mathematical cycle (Secondary School of Physics and Mathematics) and a typical Secondary School. The questionnaire contained questions for the evaluation of the educational process on the factors “Complexity”, “Time”, “Additional load”. A comparative assessment of the compliance of the educational process in the secondary school of the FMC and the secondary school with the requirements of Sanitary Regulations and Norms (SanPiN) 2.4.2.2821-10 was carried out. Results. In secondary school of Physics and Mathematics, the intensity index of the load by the factor “Difficulty” was 1.8 times more and the ration of students with a high intensity of the educational process by the factor “Time” exceeded by 3 times if compared to the secondary school, and. Every fourth school student of specialized classes attended 2-3 additional education institutions. The shortage of training rooms reached 32%. Established violations in the organization of changes and breaks between shifts, load distribution during the week. The total weekly educational load at the first level of education exceeded the standard values by 20%. The total weekly workload during training at the second and third levels of education in secondary school Physics and Mathematics exceeded indices of secondary school by 1.3-1.4 times. Discussion. When introducing new specialized programs, the actual organization of the educational process does not meet sanitary requirements, which can lead to fatigue and the development of profound and lasting changes in the body of schoolchildren. Conclusion. In the school with in-depth study of subjects, the educational process is more intense. As part of the control and supervision activities in general education organizations of the innovative type, it is necessary to pay special attention to meeting the requirements of section X of Sanitary Regulations and Norms (SanPiN 2.4.2.2821-10).

Introduction. The criteria used for the sanitary-bacteriological assessment of the quality of tap water should ensure its epidemic safety, which is important when choosing priority indicator microorganisms, quantitative determination of which will allow characterizing the risk of intestinal infections associated with water use conditions with sufficient reliability. Material and methods. Analyzed water studies for 10 years for the presence of sanitary-indicative bacteria in the water of surface water bodies in accordance with the guidelines MUK 4.2.1884. To isolate and quantify Salmonella, there were used the conventional magnesium medium and the developed nutrient medium, ready for use. The obtained data were processed using the statistical software package Statistic for Windows. Results. It has been established that E.coli can be considered as an additional indicator in order to assess recent fecal contamination. The absence of E.coli in drinking water does not guarantee the absence of other members of the family Enterobacteriaceae. Pathogenic and potentially pathogenic bacteria exhibited the greatest viability. E. coli turned out to be less stable, i.e. microorganisms, on an indication of which the system of sanitary and epidemic safety of the water use was built. In the experiments, lactose-positive coliform bacteria were established to be less resistant to the action of disinfecting agents than salmonella and potentially pathogenic bacteria, which should not be inherent to the indicator microorganism. Conclusion. Research results indicate that the absence of normalized lactose-positive fecal indicators fails to guarantee the absence of infectious agents since lactose-negative enterobacteria are unaccounted for - pathogenic and potentially pathogenic species causing intestinal infections. Therefore, in the sanitary-bacteriological control of tap water, it is more expedient to focus on the indicator glucose coliform bacteria (GKB).

Introduction. An investigation aimed at studying the modern specific features of the physical development of children of school age of Yekaterinburg city was performed. Material and Methods. Somatic (body length, body weight, chest circumference) and physiometric (vital lung capacity, hand strength) physical development indices of 1378 school students of the city of Yekaterinburg aged from 8 to 16 years were surveyed and studied using the anthropomorphic measurement method (cross-sectional studies). The obtained results were compared with the equivalent physical development results collected from the children within the period between 1894 and 2000, as well as physical development data of school students residing in the large cities of the Russian Federation; Student’s t-test, regression analysis were used. Results. A decline in somatometric indices of the physical development (body length, weight, chest circumference) in all age and gender groups of school students was noted within the period between 1894 and 2017, but the decreased average values of the physiometric parameters, i.e. vital lung capacity, hand strength, were noted from 1985. The average body length and average body weight of school students of the city of Yekaterinburg are not significantly different or higher as compared to the peers residing in the large cities of the Russian Federation. In contrast to the regional physical development standards (as of 2000), each third school student has high or higher than average physical development indices: body length by 26.4%, body weight - 36%, chest circumference - 29.8%; a high incidence of low physiometric parameters was noted: low and lower than average indices of the vital lung capacity are characteristic to 35.1% of school students, hand strength - to 20.4% (right) and 22.9% (left) school students. Conclusion. The obtained results are indicative of the epoch-making changes in the physical development of children of the school age, as well as of certain regional distinguishing features, which may be associated with changes in the social and economic, environmental situation, and life style peculiarities of the modern school students.

The study of actual nutrition and nutritional status was conducted in 180 residents of the settlements of Tazovsky and Gyda of the Yamal-Nenets Autonomous District. In comparison with the out-of-town population, Arctic indigenous people reliably consume bakery products, meat products (due to venison), fish and fish products, and less - dairy products, vegetables and mushrooms, fruits, berries, dried fruit, vegetable, fruit and fruit juices. When analyzing the chemical composition of the diet, in comparison with the indices of the newborn population, the caloric content of the ration was significantly higher because of its higher protein content (18% of calories). The fat content in the diet of the indigenous population was almost close to the recommended values (30% by caloric content), while in the alien population it exceeded them (33%). The indigenous population, in comparison with the out-of-home population, had a lower content of total and animal fat in the diet, mono- and disaccharides against a background of lower BMI (27.2 kg / m2 and 28.8 kg / m2, respectively) and fat mass. Body factors also were affected by genetic factors. The indigenous population consumed less Vitamin C (2 times) compared to the alien, which was due to the significantly lower content of vegetables, fruits, berries and fruit juices in their diet, and Ca at an unfavorable ratio of Ca: P (1: 2.5) On the background of insufficient intake of dairy products, and more - sodium due to canned (smoked, dried and salted) fish.

Published: May 2019

Introduction. Persistent organic pollutants (POP) are extremely dangerous compounds contaminating the environment and exerting the negative impact on human health. Organochlorine pesticides, including hexachlorobenzene, are a specific group among POP. Our research goal is methodological support for the hexachlorobenzene content control in human biological environments. Material and methods. We developed highly both sensitive and selective procedure for determining hexachlorobenzene in blood. Hexachlorobenzene determination in blood is based on the application of capillary gas chromatography with linear programming of a column temperature, electron capture detector (ECD), and extraction with an organic solvent at a sample preparation stage. When implementing the developed methodology, the following indices were evaluated: accuracy and error characteristics of the analysis results. The lower limit of hexachlorobenzene quantification (LOQ) in blood amounted to 0.000024 µg/cm3, with the range of detectable concentrations from 0.00015 to 0.005 (determination method error ≥ 20%), which allows to adequately diagnose chemical burden with a highly toxic persistent organic pollutant in blood. Results. The results of quantitative chemical analysis of hexachlorobenzene contents in blood had the following quality indices: precision and correctness amounted to 15.621%; repeatability - 3.45%; reproducibility - 4.65%. In the process of testing the method, concentrations of hexachlorobenzene in the range of 0.0003 ± 0.0001 ÷ 0.0007 ± 0.0001 μg/cm3 were detected in the blood of the examined group. Discussion. The high efficiency of gas chromatography determination of hexachlorobenzene in blood was achieved via selection of optimal conditions for chromatographic analysis: capillary column HP-1- 35m∙0.32mm∙0.25µm with linear programming of column temperature, carrier gas (nitrogen), electron capture detector (ECD). The developed method of the preparing a blood sample for analysis, including liquid extraction with toluene, protein denaturation by centrifuging the biological medium at 7000 rpm for 15 min at pH of 6-7 in combination with gas chromatographic analysis and an electron capture detector (ECD) made it possible to complete extraction of hexachlorobenzene from blood in an amount of 99.7%.

Este relato propõe uma metodologia que permite identificar e classificar o comportamento estratégico empresarial. Realizou-se um estudo setorial dos frigoríficos brasileiros que produzem carne de alta qualidade por meio do Programa Carne Angus Certificada, tendo em vista que estas empresas, em estrutura de oligopólio, são mais prospectoras e analíticas para as dimensões organizacionais apontadas na literatura. Os procedimentos metodológicos envolveram: i) fundamentos teóricos e empíricos que abordam o comportamento empresarial a partir do estudo seminal de Miles and Snow (1978); ii) concepção do instrumento metodológico para identificação do comportamento estratégico predominante dentro de uma empresa; iii) aplicação e validação do modelo nas quatro principais empresas do setor no Brasil. Os resultados demonstram que os comportamentos prospectivo e analítico são predominantes nos principais processos decisórios, mas existem evidências de comportamento defensivo. As evidências desse relato geram implicações teóricas quanto ao instrumento metodológico e prática ao demonstrar as formas de comportamentos estratégicos

Realizamos uma pesquisa bibliométrica utilizando o métodos de acoplamento bibliográfico, no qual extraídos utilizando o software VOSViewer, três clusters que proporcionaram a definição dos seguintes cenários:  Comunidade de investigação, Interação e-learning e Ambientes de aprendizado combinado. Concluímos que a interpretação das tendências de estudos futuros transformadas em cenários para a EaD em IES, são úteis para a gestão desse modelo de educação que está em ascensão e que no futuro poderá dominar o método tradicional de ensino, mas os três cenários apresentados também evidenciaram que a interação não deixará de ser fator importante de satisfação.

The procedure of each cycle consists planning, action, observation, evaluation and reflection. The purpose of the researcher was to investigate whether the use of Three Step Interview[Must it be capitalized?] technique can improve student’s speaking ability in SMAN 1 Asera. There were 28 students, which is 6 males and 22 females. The instrument that used in this study was speaking test, observation sheet, and photograph. The researcher found that through Three Step Interview technique at eleventh grade of SMAN 1 ASERA could improve student’s speaking ability. It was evidence by the students achievement in the first cycle which was 55,57% ≤ 75. This indicates that Three Step Interview Technique could improve student’s speaking ability.Keywords:  speaking, cooperative learning, three step interview
État des lieux des pertes alimentaires et potentiel d'utilisation des sous-produits animaux par les filières animales

L’INRA a confié à ses groupes « filières » une étude (2015-2016) visant à analyser et à quantifier les pertes alimentaires aux stades de la production agricole et de la transformation. Cet article synthétise le travail sur les filières animales. Grace à la construction d’une méthodologie par bilan de masse, l’étude a permis d’analyser le devenir des deux types de retraits pratiqués : les denrées alimentaires écartées de la consommation humaine et donc susceptibles, selon la définition de l’étude, d’induire des pertes alimentaires, d’une part, et les matières inconsommables par l’Homme d’autre part, lesquelles contribuent ensemble à la production des Sous-Produits Animaux (SPA). Les taux des pertes alimentaires varient de 3 à 8 % environ dans les filières animales, en lien avec les particularités d’espèces (sensibilité aux encéphalopathies spongiformes transmissibles, notamment). Les pertes alimentaires sont majoritairement liées à la valorisation des SPA en « pet food », sauf dans la filière bovine où la fraction incinérée est importante. En ce qui concerne les parties inconsommables pour l’Homme, l’alimentation du bétail et le « pet food » jouent un rôle différent selon les filières de provenance. Une part modeste (de 1 à 5 % chez les espèces terrestres, 15 % chez les poissons) donne lieu à une valorisation en alimentation du bétail et de façon indirecte à l’alimentation humaine. Cette partie serait beaucoup plus élevée encore si la part dédiée au « pet food » (laquelle varie de 6 à 25 % selon les filières) était réorientée au moins en partie vers les aliments du bétail. Notre étude a permis de montrer que les animaux d’élevage, et en particulier les monogastriques, ne sont pas que concurrents de l’Homme pour les ressources alimentaires, mais rendent service par la valorisation des sous-produits animaux et de ce fait, par la « non-mobilisation » de ressources.
OPINIÓN PÚBLICA Y DERECHO A LA SALUD EN EL CONTEXTO DE UNA SOCIEDAD COMPLEJA PUBLIC OPINION AND RIGHT TO HEALTH IN A COMPLEX SOCIETY
Authors: Zalazar Claudia , Martini Sandra Regina
Published: May 2019

En una sociedad compleja, la comunicación desempeña un papel fundamental, incluso con relación a la opinión pública y su manipulación en lo que se refiere a la corrupción de sistemas sociales y, en especial para este artículo, el sistema de salud. El objetivo es demostrar que la corrupción ocurre cuando un sistema opera con el código de otro sistema social. Para ello, el marco teórico y la metodología utilizados fue la Teoría General de los Sistemas Sociales. Se concluyó que la sociedad es una red de comunicación en la que cada sistema social opera con su código, so pena de configurarse en corrupción y que esa corrupción, así como noticias falsas, existe en el sistema de la salud y tiene como consecuencia la exclusión de los tradicionalmente excluidos.

Culture systems for 3-dimensional tissues, such as multicellular spheroids, are indispensable for high-throughput screening of primary or patient-derived xenograft (PDX)-expanded cancer tissues. Oxygen supply to the center of such spheroids is particularly critical for maintaining cellular functions as well as avoiding the development of a necrotic core. In this study, we evaluated 2 methods to enhance oxygen supply: (1) using culture plate with gas-permeable polydimethylsiloxane (PDMS) membrane at its bottom and (2) embedding hydrogel beads in the spheroids. Culturing spheroids on PDMS increased cell growth and affected glucose/lactate metabolism and CYP3A4 mRNA expression and subsequent enzyme activity. The spheroids comprised 5000 Hep G2 cells and 5000 20 µm-diameter hydrogel beads did not develop a necrotic core for 9 days when cultured on a gas-permeable sheet. In contrast, central necrosis in spheroids lacking hydrogel beads was observed after day 3 of culture, even when using PDMS. These results indicate that the combination of gas-permeable culture equipment and embedded hydrogel beads improves culture 3D spheroids produced from primary or PDX-expanded tumor cells.
Sustainable Business Models in Biosphere Reserves: Case of Hungary
Authors: Mosavi Amir
Published: May 2019

The goal of Man and the Biosphere (MAB) Programme is to support sustainable development through effective management, innovative technologies, policy suggestion and governance. Today, the concept of Biosphere Reserves plays an important role in scientific investigations, generating knowledge, and experiences to link socio-economic development and biodiversity conservation for human well-being. This research, through an independent study which takes place in the Hungarian Biosphere Reserves of Pilis and Kiskunság aims at identifying practical sustainable business models which are suitable for supporting livelihood of locals. In this research, the two Biosphere Reserves serve as the learning sites under the light of global principles and state-of-the-art-of knowledge on sustainable development and sustainable business models. To do so, the state-of-the-art-of sustainable business model has been investigated through a comprehensive academic research. The lessons that learned from this investigation are used to support the data gathering method and planning the field trips to identify the sustainable business models currently in use at the Biosphere Reserves. This research particularly had been interested in small-sized sustainable business models practiced by small communities or families in various zones of Biosphere Reserves. First set of interviews and questionnaires designed to identify the business models in practice. The results identify foraging the wild plants in the buffer zone and transition areas as a potential sustainable business model in practice. Further interviews and surveys were conducted with foragers shows the beneficial of their practice on the local ecosystem and in increasing awareness on the deep connection with the ecosystems. The sustainable business model of foraging in addition to providing a sustainable livelihood for the locals maintains a spiritual connection between people and land. The identified sustainable business model can further be educational and practical for other 685 biosphere reserves.
'You Scratch My Back and I'll Scratch Yours'? Support to Academics Who Are Carers in Higher Education
Authors: Moreau Marie-Pierre , Robertson Murray
Published: May 2019

In recent years, it has become common for individuals to juggle employment and unpaid care work. This is just as true for the England-based academic workforce, our focus in this article. We discuss how, in the context of English HE, support for carers is enacted and negotiated through policies and practices of care. Our focus on academics with a diverse range of caring responsibilities is unusual insofar as the literature on care in academia is overwhelmingly concerned with parents, usually mothers. The article is informed primarily by critical and post-structuralist feminist perspectives. We draw on a corpus of 47 interviews conducted with academics representing a broad range of caring responsibilities, subjects, and positions. A thematic analysis reveals how carers’ relationship with the provision and policies of care support at institutional level is characterised by ambiguity. On the one hand, participants approve of societal and institutional policy support for carers. On the other hand, they are often reluctant to position themselves as the beneficiary of such policies, expressing instead a general preference for support from outside the workplace or for workplace-based inter-individual and informal care arrangements. This resistance is particularly noticeable in the case of participants with caring responsibilities other than the parenting of healthy, able-bodied children and of those whose gender, class, racial, or sexual identity do not conform with the figure of the ‘ideal academic’, contributing to their othering in the academic realm. These findings have significant implications for policies supporting carers, pointing to the need for greater visibility and recognition of caring responsibilities in academia, especially in terms of their diverse identities.
A Systematic Review of Intercultural Education in the Promotion of Sustainability by the Development of Education Programs and Educational Interventions Targeting the Roma Student

Intercultural education can be seen as a cornerstone in the sustainability of the current culturally diverse society. In addition, through the establishment of policies and strategies to reverse situations of discrimination and exclusion, there is a consensus on the importance of the social inclusion of groups at risk of exclusion. In this context, actions are suggested to reverse high dropout rates and school failure within the Roma population. The aim of this systematic review in the educational context is to analyze investigations of programs and interventions that have been made to promote the educational inclusion of Roma students. Three databases are used, Scopus, Web of Science, and Eric, to examine 419 articles, which after a selection, based on an inclusion criterion which follows the guidelines given by the Declaration PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyzes), 17 articles were chosen for the analysis. The main findings shed light on data for programs and interventions developed mostly within the school setting and for students of elementary and secondary education. These programs provide answers for the molding of intercultural education and the policies for educational inclusion of Roma people.
