Published: December 2017

La necrópolis del oppidum de Monte Bernorio fue uno de los primeros cementerios de la Edad del Hierro excavados en España. No obstante, la atención a los excepcionales materiales metálicos descubiertos en ella, unido a la escasez de restos relacionados con los rituales, ha impedido conocer hasta este momento qué tipo de ceremonias funerarias se desarrollaron en ella. En este trabajo se presentan los diversos estudios y análisis realizados sobre las evidencias recuperadas en las excavaciones de las campañas de 2007 y 2008, así como los resultados obtenidos y las interpretaciones que de estos hemos realizado. El resultado es la identificación de un tipo de ritual que invisibiliza los restos y que implica un uso diferente de los espacios funerarios.

Authors: Lima Paula Stephane De Souza
Published: December 2017

A dança é considerada uma manifestação cultural do movimento corporal e quando associamos ao âmbito escolar, é capaz de promover a transmissão de sentimentos, emoções e capacidades criativas e motoras da criança. Diante disso, o presente artigo teve como objetivo apresentar a importância da dança na pré-escola. Este estudo foi conduzido com a base de dados entre os meses de setembro a outubro de 2017. As pesquisas foram investigadas a partir de pesquisa bibliográfica disponibilizadas em bases de dados eletrônicos como scientific electronic library online (SCIELO), Google Scholar e periódicos da CAPES com QUALIS A, B e C, bem como as publicações listadas no site de Programas de graduação e Pós-graduação em pedagogia e em outras organizações atuantes no universo da educação. Após as análises da literatura, foi observado que a dança é capaz de promover o desenvolvimento corporal das crianças, melhorar a capacidade cognitiva e expandir sua habilidade intelectual. Dessa forma, é fundamental que os alunos da pré-escola, bem como nas demais modalidades de ensino, tenham a dança como ferramenta no universo pedagógico capaz de promover a educação e melhoria da qualidade de vida dos alunos.

Authors: Ridayanti Neneng
Published: December 2017

Artikel ini menganalisis mengenai peranan Perfini dalam membangun dan mengembangkan identitias perfilman Indonesia pada 1950-1970. Seperti yang telah diketahui, identitas film yang dibuat di tanah air pada masa kolonial hingga pendudukan Jepang, memiliki cerita yang tidak jelas karena dianggap tiruan dari film Cina, Amerika, ataupun India. Pada awal  1950-an rasa nasionalisme rakyat Indonesia bangkit kembali.  Penduduk kota yang mengungsi ke desa-desa akibat perang, mulai kembali dan membutuhkan hiburan.  Hal ini, mendorong maraknya produksi film Indonesia.  Perusahaan film milik Tionghoa mulai bangkit kembali, begitupun dengan kaum pribumi.  Inilah merupakan awal dari pertumbuhan perfilman nasional di Indonesia. Dengan menggunakan metode sejarah diharapkan mampu mengurai dan mengidentifikasi posisi dan peranan organisasi ini dalam dunia perfilman Indonesia.
Purchasing decisions at private hospitals in the framework of resource dependency theory
Authors: Uygun Meltem
Published: December 2017

The environment influencing hospitals in the health industry is quite complicated, and despite the high volume of inputs, the functions that occur at purchasing level are very intricate. The reason that the feedback mechanism of health services is not organized completely, and thus another reason that the health system is quite complicated, is diversification of inputs and the consequent rising volume of inputs from the environment, and high dependency on the environment.  Governing the demands and pressures of the environmental actors and reorganizing them for its own benefit are only possible for the business, depending on how much power it has in the interdependent relationship. Therefore, it is necessary to clarify the role of power as a concept when analyzing these environmental relationships in order to elucidate the behaviors of organizations. This study addresses power relations in the framework of resource dependency theory. The "power and dependency relationship" of the actors that are influential in purchasing decisions regarding clinics at a private hospital where physicians, who are experts in their field work, is the proposal of this research. The matter of which actors (hospital upper management, purchasing department, relevant expert physicians) have an influence on purchasing decisions and mutual relations are discussed in the context of power.
OSL chronostratigraphy for loess deposits from Tyszowce – Poland
Authors: Moska Piotr , Adamiec Grzegorz , Jary Zdzisław , Bluszcz Andrzej
Published: December 2017

The presented work concerns a loess profile located in Tyszowce, in the eastern part of Poland on the Volyn Upland, close to the Ukrainian border. The investigated loess formation is well preserved and is characterised by clear stratigraphic units providing an opportunity to refine the loess chronostratigraphy in Poland. In the paper, we present luminescence ages of loess from the last glacial cycle in SE Poland (up to about 100 ka) together with seven radiocarbon ages. Twenty-one samples were collected and dated using infrared (post-IR IRSL) and blue light stimulated luminescence dating. Two fractions were used, namely polymineral fine grains (4–11 μm) and medium sized quartz grains (45–63 μm). The obtained luminescence ages show very good agreement of both methods in relation to loess deposits, however for the fossil soil units the post-IR IRSL method yields older ages. Radiocarbon dates also confirm luminescence chronostratigraphy for younger units. Moreover, the luminescence results are supported by detailed analyses of grain size distribution, carbonate content and magnetic susceptibility variations allowing to create a comprehensive picture of chronological evolution of this site.

Authors: Ozsu Elif , Sen Askın , Ceylaner Serdar
Published: December 2017

Background:

Bannayan Riley Ruvalcaba syndrome (BRRS) is exceedingly rare, with only about 50 reported cases to date.

Case presentation:

We report a patient with hypoglycemia, precocious puberty and diffuse testicular microlithiasis accompanying BRRS, and think that this case is important in the light of a newly identified mutation in the PTEN gene.

Conclusions:

Close attention must be paid in terms of PTEN mutations in cases of macrocephaly and accompanying neurological and dermatological findings.
Chlorogenic acid prevents alcohol-induced brain damage in neonatal rat
Authors: Guo Zikang , Li Jiang
Published: December 2017

The present investigation evaluates the neuroprotective effect of chlorogenic acid (CA) in alcohol-induced brain damage in neonatal rats. Ethanol (12 % v/v, 5 g/kg) was administered orally in the wistar rat pups on postnatal days (PD) 7-9. Chlorogenic acid (100 and 200 mg/kg, p.o.) was administered continuously from PD 6 to 28. Cognitive function was estimated by Morris water maze (MWM) test. However, activity of acetylcholinesterase, inflammatory mediators, parameters of oxidative stress and activity of caspase-3 enzyme was estimated in the tissue homogenate of cerebral cortex and hippocampus of ethanol-exposed pups. It has been observed that treatment with CA attenuates the altered cognitive function in ethanol-exposed pups. There was a significant decrease in the activity of acetylcholinesterase in the CA treated group compared to the negative control group. However, treatment with CA significantly ameliorates the increased oxidative stress and concentration of inflammatory mediators in the brain tissues of ethanol-exposed pups. Activity of caspase-3 enzyme was also found significantly decreased in the CA treated group compared to the negative control group. The present study concludes that CA attenuates the neuronal damage induced in alcohol exposed neonatal rat by decreasing the apoptosis of neuronal cells.
Metáforas de la selección natural
Authors: Vilas Peteiro Román
Published: December 2017

Buena parte de la elegancia del concepto de selección natural reside en una falsa aparienciade sencillez, y a menudo se expresa metafóricamente. En este artículo reviso diferentesmetáforas de la selección natural con el fin de revelar algunas complejidades ocultas. Enrealidad, el concepto de selección natural es un concepto difícil estrechamente relacionadocon otros conceptos complejos, tales como el concepto de eficacia biológica y de adaptación.Una discusión sobre las metáforas de la selección natural es pertinente porque la imagenque ellas evocan puede obstaculizar la investigación del proceso natural al cual se refieren.

Reconstrucción estructuralista de la teoría de la selección natural
Authors: Ginnobili Santiago
Published: December 2017

Aunque parece una teoría relativamente simple, la teoría de la selección natural ha traído muchas discusiones al respecto de su reconstrucción. En particular, los autores han tenido dificultades a la hora de elucidar el concepto de aptitud (fitness) adecuadamente. El punto de vista de este trabajo consiste en que para entender adecuadamente esta cuestión, y además, para dar cuenta de manera adecuada de las explicaciones seleccionistas, tanto las dadas por Darwin como sus aplicaciones más actuales, es necesario a la hora de reconstruir la teoría utilizar más conceptos de los que habitualmente se utilizan. En este trabajo se explayará sobre este punto y se presentará una reconstrucción de la teoría en cuestión con las herramientas del estructuralismo metateórico.
Estructura y génesis de la teoría humoral de la inmunología
Authors: Lorenzano César
Published: December 2017

En este artículo se analiza la teoría humoral de la inmunidad propuesta por Paul Ehrlich en 1900, precedida de un conjunto de brillantes investigaciones que al tiempo que parecieran refutar a la teoría anterior –la teoría celular de la inmunidad– fueron el terreno privilegiado en el que se sustentó. Historiaremos esas teorías y experiencias previas, para presentar a continuación el artículo fundacional de la teoría humoral. Nos basaremos en estos hallazgos para caracterizar la estructura de la teoría, utilizando una versión modificada de la concepción estructuralista. Mostraremos cómo teorías previas de otros campos son utilizadas por Ehrlich para proponer su propia teoría, y cómo las experiencias y teorías anteriores del campo inmunológico integran su base empírica. Al hacerlo incursionaremos en el contexto de descubrimiento de la inmunología, proponiendo que consiste en un proceso constructivo. Finalmente, mostraremos la forma que adopta la transición entre la teoría celular y la humoral de la inmunidad.
Sobre la noción de “forma de vida” en Wittgenstein
Authors: Marrades Julián
Published: December 2017

En el artículo se analizan los pasajes más relevantes donde Wittgenstein emplea la expresión‘forma de vida’ (Lebensform), estableciendo conexiones entre sus diferentes sentidos. Acontinuación se exponen dos interpretaciones de esta noción –la orgánica y la cultural–, quealgunos autores consideran excluyentes entre sí, y se discute críticamente la unilateralidadde ambas interpretaciones y su status teórico. Finalmente, se propone una interpretaciónque permite compatibilizar trascendentalismo y naturalismo, habida cuenta de la funciónmetodológica que Wittgenstein atribuyó a la noción de ‘forma de vida’ en su análisisconceptual de las condiciones de la comprensión del lenguaje.
Os governos Roseana Sarney e Flávio Dino nas manchetes de O Estado do Maranhão
Authors: Silva Sousa Li-Chang Shuen Cristina
Published: December 2017

Neste artigo, apresentamos parte dos resultados da pesquisa Governando Contra as Notícias: o primeiro ano do Governo Flávio Dino nas páginas de O Estado do Maranhão. Analisamos a mudança de paradigma enfrentada pelo jornal a partir da posse de um governador de oposição ao grupo Sarney. Analisamos as chamadas de capa publicadas em 2014 e 2015, governos de Roseana Sarney e Flávio Dino, respectivamente. A metodologia utilizada foi a combinação de análise de valência com análise textual. Concluímos que o jornal, apesar de seguir formalmente os critérios de noticiabilidade e valores-notícia em sua cobertura durante o mandato de Roseana, adotava um discurso jornalístico-publicitário, atuando como relações públicas das ações governamentais naquele período, especialmente em assuntos negativos para o governo. A partir da posse de Dino, o jornal passa a atuar no campo oposicionista e abandona completamente o discurso positivo, transformando sua cobertura em um exercício de jornalismo adversário e atuando como arena de diálogo entre as elites em disputa pela hegemonia no Maranhão.
Improved analytical solution of vertical pressure on top of induced trench rigid culverts
Authors: Qin X. , Ni P. , Zhou M.
Published: December 2017

Induced Trench Installation (ITI) is a viable option to reduce the load on rigid culverts buried under high embankments. However, reliable design methods are limited, which restricts further applications of this technology. Based on Marston's formula, a modified analytical solution is proposed, in which the vertical stress across the width of the soil column immediately above the compressible layer is assumed to be distributed in a parabolic shape, and the effects of the geometry and stiffness of the soft layer on load reduction are considered explicitly. Comprehensive comparisons are made between field monitored results and the calculations from different design methods. Parametric studies are subsequently conducted to investigate the influence of different distribution patterns of vertical stress and the properties of the soft layer. It is found that compared to Marston's theory, the proposed method yields a closer estimation to the field measured data. Finally, a simplified design chart is introduced, which can facilitate use of the proposed method.

Published: December 2017

La formación y el entrenamiento en el desarrollo de las capacidades de visión e imaginación espacial durante la educación incrementan la habilidad de formar imágenes, y el rendimiento en las tareas que las utilizan. En esta investigación se analizó si el tipo de estudios (Arquitectura, y Administración y Dirección de Empresas) y la capacidad de rotar imágenes mentales influían en el número de aciertos, errores, y aciertos menos errores, en la rotación de mapas urbanos. Con este fin, se seleccionó  un grupo de 208 estudiantes universitarios de Arquitectura, y de Administración y Dirección de Empresas, y les presentamos una tarea que consistió en analizar si la posición de 90 pares de mapas urbanos era igual o simétrica. Se evaluó el número de aciertos, errores, y aciertos menos errores. Se encontró que, tanto el tipo de estudio como la habilidad para rotar imágenes influyeron en el número de aciertos (sin contabilizar los errores),  y en el número de rotaciones correctas (aciertos menos errores). La habilidad de rotar imágenes mentales también influyó en el número de errores en la rotación de mapas urbanos.

Aims

Sarcopenia has recently been given an ICD‐10 code. However, there have been no systematic investigations regarding the prevalence or prognostic value of sarcopenia in cardiovascular disease (CVD) according to the international consensus definition. The present study was performed to investigate the prevalence and prognostic value of sarcopenia in elderly patients with CVD.

Methods and results

The study population consisted of 1603 admitted patients aged ≥ 65 years (74.4 ± 6.2 years, 1049 men) with CVD. Sarcopenia was defined according to the recommended diagnostic algorithm of the Asia Working Group for Sarcopenia. The endpoint for the study was all‐cause mortality. The overall sarcopenia prevalence rate was 29.7% (19.6% in men and 48.7% in women). The prevalence rates of sarcopenia across major diagnostic categories were as follows: acute coronary syndrome, 17.8%; post‐cardiac surgery, 31.8%; and heart failure, 35.2%. During the 2.3 ± 2.1‐year follow‐up period, 175 deaths occurred. Patients with sarcopenia showed higher risk of all‐cause mortality compared with non‐sarcopenic patients (adjusted hazard ratio: 1.44; 95% confidence interval: 1.01 – 2.05; P = 0.044).

Conclusions

Sarcopenia is highly prevalent among elderly patients with CVD and is associated with increased mortality risk.

Contamination with trace elements is characterized by an abiotic stress that represents a limiting factor in agricultural production. As cadmium (Cd) and Zinc (Zn) are physically and chemically similar, they can interact with the environment, causing antagonistic or synergistic effects. In this sense, physiological mechanisms to exclude detoxify or compartmentalize the excess of those trace elements is crucial for the survival of the vegetables when they are exposed to high concentrations of those elements. To comprehend the responses of the species sensible to the presence of Cd and Zn, this study aims to access the behavior of corn plants (Zea mays) cultivated in Cambisoils and Latosol with growing concentrations of Cd/Zn in a 21 days period. We performed growth and biochemical analyzes like antioxidant enzyme SOD, CAT and APX activity, hydrogen peroxide and lipidic peroxidation. Our data showed the specific behavior of cultivated corn plant in each of the soils analyzed. We observed that the interaction between both the elements resulted in a synergistic effect, negatively influencing all the analyzed parameters.

Published: December 2017

Currently, sweet sorghum has presented great expansion of cultivation in traditional areas and new technologies sugar and alcohol sector. The aim was to to identify what agronomic traits can be used for indirect selection of genotypes with higher sugar yield. The work was conducted in the harvest 2014/2015, at Embrapa Agropecuária Oeste, in Dourados, MS. It were evaluated 25 genotypes in experimental design was a randomized block design with three replications. We evaluated the following agronomic traits: plant height, fresh mass, percentage of stem, leaves and panicles, dry mass, Brix, yield of juice and sugar. The F-test was used to check for genetic variability among genotypes. Phenotypic correlations among these traits were estimated, which are deployed through the path analysis, in direct and indirect effects, considering the yield sugar as the primary dependent variable. We observed that 92% of the variation in sugar yield was explained by the explanatory variables, value higher than in other studies and appropriate to explore the gains with indirect selection in sweet sorghum. The indirect selection based on Brix trait is the most effective way to obtain genetic progress in the sugar yield in sorghum genotypes.

Published: December 2017

Esse experimento foi realizado com o objetivo de propor o número de plantas na avaliação de híbridos simples de milho, se há necessidade de bordadura nos experimentos e se as diferentes linhas das parcelas afetam o desempenho dos híbridos. Foram avaliados seis híbridos simples comerciais no delineamento de blocos casualizados, com três repetições e parcelas de quatro linhas, com 40 plantas por linha. A colheita foi realizada por planta georreferenciada em cada linha/parcela. Para cada tamanho de parcela foram efetuadas 1000 reamostragens sendo realizadas as análises de variância, e estimada a acurácia e a coincidência na identificação dos dois melhores híbridos identificados na parcela padrão (160 plantas). Não há necessidade de bordadura e o desempenho dos híbridos não varia em função das linhas das parcelas. As estimativas da acurácia e a coincidência dos experimentos em identificar os dois melhores híbridos são muito grandes, em relação ao emprego de 160 plantas, a partir de parcelas com 50. A variação dentro das parcelas é sempre inferior à observada entre parcelas. Portanto, para reduzir custos e melhorar a eficiência dos programas de melhoramento de milho, as parcelas de avaliação de híbrido simples não necessitam ter mais do que 50 plantas.
Las competencias normativas de las autoridades administrativas en materia de contratación estatal en Perú
Authors: Morón Urbina Juan Carlos
Published: December 2017

La ley peruana ha reconocido expresamente competencias normativas a las entidades del Poder Ejecutivo, por lo que, en ejercicio de facultad reglamentaria, diversos actores públicos presentan un papel preponderante en la creación de las fuentes del ordenamiento jurídico en materia de contratación estatal. Sin embargo, el hecho de que las competencias se encuentren delimitadas positivamente no evita la aparición de distorsiones en el sistema de fuentes, ya sea porque las entidades públicas exceden sus facultades o porque equivocadamente se reconocen como normas a instrumentos emitidos por estas que no califican como tales. Bajo este contexto, el presente artículo tiene como propósito identificar a aquellas entidades que hacen ejercicio de potestad reglamentaria, así como los instrumentos normativos que crean y su relación con el resto de fuentes jurídicas que regulan la contratación estatal, para finalmente analizar, en los hechos, las distorsiones antes referidas.

Information and communication technologies have established themselves in all areas of human life. We use these technologies for work but also for entertainment. Computers facilitates numerous activities. New technologies also bring new problems. Therefore, educational institutions must respond to this situation. Children use computer devices very often, also to the detriment of their movement. Children also use a lot of mobile devices. There is a tendency to use mobile devices in the classroom and find new teaching methods. According to international research has current way of life negatively affects health, especially children. Children too much time sitting at the computer, stare into its smartphones, watching television for a long time. They move little and they carry little activity outside. The paper describes case study among children. We used questionnaire method and long-term observation. The first questionnaire was completed by 138 students aged 11 to 19 years. Obtained data are processed by statistical methods. For analysis of the results in each item was measured as having detected data variability. We used a coefficient of variation. To interpret the results of the second stage classification was done chi-square test. We've also used a case study. We are within one year we observed 15 boys aged 10 to 17 years. We have focused on observing their physical condition, any manually abilities, use of leisure time.

Authors: Dugan Omur , Bozyiğit Elif , Henry Ian
Published: December 2017

The goal of the â€˜Olympic Movementâ€™ is to contribute to building a peaceful and better world by educating youth through sport practices with Olympism and its values. To contribute to the Olympic Movement; Culture and Olympic Education Commission of Turkish NOC, has prepared an interactive Olympic education project called â€œOLIâ€ since 2009, which reached 3 million students. It is very important to develop a means to analyze if the Olympic education program OLI fullfills its aims. Therefore the research question of this study is â€œWhat are the principal aims of the OLI program and how can we develop an evaluation procedure to assess the extent to which these aims are achieved?â€ A sample group was a class of students (n=33) who participated in the OLI education. The methodology of the study included developing the survey from the context of education given to evaluate the program. Before and after case study was conducted to the students. The questions developed were related to knowledge about the modern Olympic Games and knowledge of attitudes associated with, Olympic values and Olympism. According to the results of the survey; the OLI project increased the knowledge about Modern Olympic Games and the knowledge of attitudes associated with, Olympic values and Olympism. The importance of the study was that; even though there is a wide range of approaches to Olympic education programs, there is indeed no detailed evaluation methods. With this study; an approach which is short, sharp, feasible and something which can be used relatively easy to implement was developed.

Authors: Aksoy Yener , Ziyagil Mehmet Akif
Published: December 2017

This study aims to investigate the effects of education and socio-economic status on regular physical activity levels in 1350 males and 1350 female participants at the age range of 14-95 years. Results of this study showed that the mean body height and weight were significantly differentiated depending on male participantsâ€™ educational status and monthly income level. There were significant differences in female participantsâ€™ body height and body weight depending on their educational status. Only significant difference was observed in the mean of femaleâ€™s body height depending on monthly income level. The physical activity level of uneducated participants was highest in males and females. Significant negative correlations were observed between physical activity and educational status in males (r=-,108, p<.01) and females (r=-,129, p<.01). It can be concluded that physical activity level in both genders was effected by educational status not monthly income level.Keywords: Physical activity, socieconomic, education level.

Lightweight Semantic based Approach to Assess Readability of Web Service Interfaces
Authors: De Renzis Alan , Garriga Martin , Flores Andres , Cechich Alejandra , Mateos Cristian , Zunino Alejandro
Published: December 2017

A Web Service has an interface described in a machine-processable format (specifically WSDL). Service providers expose their services by publishing their WSDL documents. Service consumers can learn about service capabilities and how to interact with services.Service descriptions (WSDL documents) should be ideally understood easily by service stakeholders so that the process of consuming services is simplified. In this work we present a practical metric to quantify readability in WSDL documents. We adapted and extended an existing ontology-based semantic readability metric to focus on WSDL documents by using WordNet as a lightweight concept hierarchy. We have validated our approach by performing both qualitative and quantitative experiments. The first one consists of a controlled survey with a group of service consumers. The results showed that consumers (software engineers) required less time and effort to analyze WSDL documents with higher readability values. The second experiment compares our approach with two ontology-based approaches. The third experiment compares the readability values of a dataset of real-life service descriptions before and after rewriting them. The resultsshowed the effectiveness of our approach to assess readability of Web Services interfaces.

Published: December 2017

This paper carried out a performance evaluation study that compares two survivability strategies (DPP and SM-RSA) for elastic optical networks with and without physical layer impairments. The evaluated scenarios include three representative topologies for elastic optical network, NSFNET, EON and USA. It also analyzes the increase of blocking probability when the survivability strategies are evaluated under the realistic scenario that assumes physical layer impairments. For all studied topologies under physical layer impairments, the survivability strategies achieved blocking probability above 80%.

REPRESENTAÇÕES SOCIAIS, HISTÓRIA E MEMÓRIA: POSSÍVEIS CONTRIBUIÇÕES PARA OS ESTUDOS ORGANIZACIONAIS
Authors: DOS SANTOS VIVIANI TEODORO , ICHIKAWA ELISA YOSHIE
Published: December 2017

A Teoria da Representações Sociais (TRS), de Serge Moscovici, inaugurou uma nova forma de pensar a construção do conhecimento, principalmente por instituir o saber do senso comum como algo que mereça ser estudado pelo campo científico. Além de compreender o processo de familiarização de um novo conhecimento, é igualmente relevante discutir o quanto essa transformação do estranho em familiar se utiliza de acervos contidos na memória, constituídos tanto por registros recentes, quanto por àqueles provenientes de um tempo histórico anterior, transmitidos de geração em geração. Desse modo, o objetivo deste estudo é conhecer as influências que a história e a memória coletiva exercem na construção das representações sociais, interferindo na constituição de um sujeito capaz de criar novas compreensões e agir por meio delas, bem como refletir brevemente, o quanto a TRS pode contribuir com os Estudos Organizacionais à medida que amplia a concepção atual de Homem adotada pelas organizações.
DEVELOPMENT OF THE IMPROVED METHODS OF FIGHT AGAINST DISTRIBUTION OF SMOKE ON SHIP WITH SYSTEMS OF JET WATER–GAS EJECTORS
Authors: Blintsov Volodymyr , Hrynchak Sergiy
Published: December 2017

The ways of improving the design of ship openings with the implementation of a method for reducing the intensity of the exit of flue gases through an opening (doors, hatches) of the emergency premise of the ship are considered. The output of flue gases from the emergency premise is proposed to be controlled by the control of gas–air currents with the help of a system of jet water–gas ejectors. Ejectors are equipped with devices for collecting flue gases from the emergency premise of the ship and the collectors of the output of the vapor–gas mixture back to the emergency premise.

In case of fire, in the shortest possible time, a high temperature rises in the area of exit from the emergency premise of the ship and a large amount of smoke spreads along the corridors and premises of the ship. These factors require immediate sealing of the emergency premise, which limits the operational access of emergency teams to combat fire.

The considered air suppression methods in the ship's aperture and devices for their implementation contribute to screening of heat energy and localization of flue gases in the emergency premise without its sealing to ensure prompt access of emergency teams.
GENETIC FEATURES OF RESISTANCE TO ANTITHROMBOCYTIC DRUGS IN PATIENTS WITH ISCHEMIC HEART DISEASE AFTER CONDUCTED PERCUTANEOUS CORONARY INTERVENTION
Authors: Liakhotska Ada
Published: December 2017

The aim of the study: To study and evaluate platelets aggregation activity as primary phase of haemostasis and anti-platelet therapy in IHD patients after PCI, depending on the polymorphism of the gene ITGA 2 - C 807T.

Materials and methods: 54 patients who were on a treatment at the clinical hospital "Feofaniya" (Kyiv) and at the Kyiv Clinical Hospital on railway transport №2 were examined: 20 women and 34 men (mean age - 67.8 ± 7.46 years). The study involved patients with stable forms of coronary artery disease (stable angina pectoris II-III) and acute coronary syndrome, with a history of percutaneous coronary intervention (PCI). All patients received antiplatelet therapy: acetylsalicylic acid (3.7%), clopidogrel (9.3%) or a combination of them (87%).

Functional activity of the platelets was studied on a Biola Aggregation Analyzer laser agrometer. The response to antiplatelet therapy was confirmed by the Aggredyne test. The polymorphism of the C807T of the ITGA2 gene was determined by polymerase chain reaction (PCR).

Based on the results of the aggregation ability, antiplatelet therapy sensitivity, the patients were divided into two groups: group I - individuals with varying degrees of insensitivity to antiplatelet drugs (35 patients), group II - susceptible to treatment (19 patients). In each group was analyzed the polymorphism of the gene ITGA2 and features of the functional activity of the platelets, depending on the genotype.

Results: In 50% of patients receiving ASA there was a different degree of non-sensitivity, with respect to thienopyridines - this figure was 20%. Among patients who received dual antiplatelet therapy did not match at least one of the drugs - 83.3%. Among the "non responders" 78.9% had a mutated T-allele, and a homozygous variant for the T allele was recorded in 53.15% of patients, while "respondents" - 15.8%. Most in the group of "respondents" was the group of the native genotype - C / C. The most pronounced tendency to influence the genotype on spontaneous aggregation was observed in relation to the T-allele, in particular in the homozygote (genotype T / T). The significant difference between the groups was obtained from the platelet response to ADP. Thus, the reaction of carriers in the T-allele, as homo- and heterozygotes, was significantly different.

Conclusions: In 64.8% of patients with coronary heart disease after PCI was observed a decrease in antiplatelet sensitivity, which has a clear link with the polymorphism of the gene ITGA 2. The presence of the T-allele in the genotype of patients with IHD is associated with a less adequate platelet response in patients receiving dual antiplatelet therapy for ASA and thienopyridines on ADP, which may have an effect on the sensitivity to thienopyridines.
MONITORING OF WASTEWATER PURIFICATION PROCESS
Authors: Shatohina Yulia
Published: December 2017

There were conducted the researches to identify new correlation between traditional controlling process indicators of cleaning stock water from phosphates and concentration of phosphates in purified water that can be used for the development of new techniques. Analytical laboratory data of the current purification station were carried out with the use of the Pearson correlation coefficient to detect a connection between concentration of phosphates in the purified water and four kinds of hydrobiological data using Microsoft Excel a computer program with functions Corel batch analysis. The most informative for monitoring of purification from the phosphates is the indicator of the number of types of hydrobionts. Change of concentration of phosphates goes in antiphase to the amount of types of hydrobionts. Therefore, for the convenience of the users there was completed the visualization of the existing trend using the introduced by the authors index-modified number of hydrobionts. There was presented an algorithm monitoring the process of sewage purification from phosphates, which requires the creation of a database and preliminary plotting of dependence of phosphates Sf concentration on the number of hydrobionts NG. The further displaying of laboratory data indicator NG on the schedule allows to predict the expected concentration of phosphates Sf in purified sewage and in case of poor forecast to carry out operational actions. The survey is based on the basis of a new methodology, which was transferred for the introduction to "Chernihivodokanal" (Chernihiv, Ukraine)

Published: December 2017

After the Elizabethkingia anophelis outbreak in Wisconsin, USA, an active search for the detection of the microorganism in hospital water systems from Central and Northern Greece was performed from June to December 2016. In total, 457 water samples from 11 hospitals were analyzed. Elizabethkingia spp. was detected in three samples collected from two hospitals, both of which are located in Northern Greece. Two of the three isolated strains were identified as Elizabethkingia anophelis. No cases of Elizabethkingia infection were reported in either hospital during 2016. This is the first reported isolation of the pathogen in water supply systems in Greece.

Authors: Carvajal Gutiérrez Carmen , Corpas Alba Juan
Published: December 2017

Para conocer la utilización de los hospitales públicos por los extranjeros se han podido conseguir los datos sobre asistencia desde el año 2.000 hasta el año 2.004 en los hospitales Virgen de la Victoria, Costa del Sol, Antequera y Carlos Haya. Los resultados obtenidos muestran que se ha producido un fuerte crecimiento en todos los tipos de asistencia hospitalaria a extranjeros pero inferior al crecimiento de la población extranjera residente en la provincia de Málaga, y también muestran un uso diferente de la asistencia hospitalaria por parte de los extranjeros procedentes de la Unión Europea respecto de los extranjeros no comunitarios.
Acreditación en Red: un sistema de acreditación distribuida para la educación continua

Published: December 2017

La educación continua involucra actividades de aprendizaje que se generalmente se realizan después de la formación tradicionalmente reglada. Una creciente oferta educativa se ha extendido en todo el mundo en forma de cursos, diplomados, postítulos y otros tipos de programas de estudio.Pese a la creciente importancia y oferta de programas de educación continua, los procesos de acreditación se han restringido a la educación reglada tradicional. Estos se caracterizan por un sistema centralizado de acreditación liderado por una autoridad gubernamental nacional. Este tipo de acreditación es difícil de aplicar efectivamente en los programas de educación continua.En la presente contribución presentamos y analizamos un sistema de acreditación en red (SAR) diseñado para la acreditación de la calidad de los programas de educación continua. Este sistema de acreditación contrasta con los ya existentes sistemas “centralizados”, por ser un sistema “distribuido”, inspirado en el sistema mediante el cual la comunidad científica internacional valida los artículos de investigación, es decir, el sistema de “revisión por pares”. En este trabajo describimos este sistema, analizamos sus fundamentos teóricos, sus potenciales ventajas y desventajas, y las experiencias de su aplicación en un primer prototipo.
