The evolution of free time throughout history. Video games as a modern leisure activity
Authors: Polcyn Sylwia
Published: October 2019

Against the background of civilizational development, the 21st century appears as a time of great opportunities of self-development and general progress but also as a time of various new leisure activities. Thanks to the society’s prosperity, as a consequence of scientific and technological research as well as technological progress, our lives have been improving on a daily basis, evolving towards “excellence”. A similar evolution has taken place in terms of leisure activities that have been known since antiquity. Some of them have slipped into oblivion, giving way to more interesting and controversial forms of leisure, including computer games. Computer games have become a part of our society; the role they have played in the 21st century is immense. Both children and teenagers are involved in this sort of pastime on a daily basis. To many of them, a day without their favourite game or virtual hero is hard to imagine. When asked about computer games, most adolescents will flood you with information on the subject. To children and teenagers, games are a source of lively colours, sounds and great opportunities. They offer a world beyond a child’s common experience. Games make a child feel needed. Most of all, computer games are more attractive and more easily accessible than other leisure activities.

Latin: Back to the Future? Some Reflections on Latin and Literacy in the Digital Age
Authors: Vogt-Spira Gregor
Published: October 2019

Vogt-Spira Gregor, Latin: Back to the Future? Some Reflections on Latin and Literacy in the Digital Age (Łacina: powrót do przyszłości? Kilka refleksji nad łaciną i kwestiami literackimi w epoce digitalizacji).This paper argues that Latin meets the challenges of this day and age so that its preservation actually has a well-founded place within European countries and societies. The argumentation starts by the observation that Latin gathers a number of additional values as an alterity training, a cognitive training, a linguistic training or a socially integrative effect, values, which are remarkably not bound to a specific culture. Above all, digitization and the modern cybernetic world is seen as a central challenge, digitization with its enormous quantitative increase in reading and writing activity also transforms the user profile in a way that complements it, a factor to which educational institutions have yet to come up with a conclusive response. Referring to this development, Latin has the particular significance of imparting the standards of an elaborate written form into the composition and decoding of texts. Furthermore, Latinity itself is considered to be one of the key factors that have shaped modern-day Europe, and the later Latin-language literature is seen to be a comprehensive component of each country’s respective national literature and culture. To conclude, the ancient European custom is brought into focus that, practically, antiquity serves as a vehicle for legitimizing modernization.

Published: October 2019

This research is the first attempt to investigate the problem of the influence of social factors on the process of the name giving taking into account – its motives. The authors made an attempt to divide and systematize social factors of different character, describe their influence on the name giver. From the linguistic point of view, the authors describe in detail the process of changing the onym semantic structure under the influence of social factors. At the modern stage of the anthroponymics progress, the researchers described only social factors influencing name giving, however, their systematization has not been made. For detailed studying of the subject, a complex analysis was carried out, which includes such techniques as comparison, classification and evaluation. The research is relevant in the linguistic, social, national and cognitive aspects, as it demonstrates an interaction between language and society.
A mystery mass on the placenta
Authors: Ting Evelyn Lee Pian , Yong Soon Leong , Suhashini Ganapaty , Kang Marcus
Published: October 2019

Chorioangioma or chorangioma is a benign placental tumour which occurs in 1% of the pregnancies. Large lesions of more than 4–5 cm in size, also known as giant chorangiomas, are rare with the incidence of 1:3500 and 1:9000 birth. Unlike small tumours, the giant chorangiomas are highly associated with pregnancy complications. We report a case of multiple large chorangiomas resulting in an extremely preterm delivery. A 24-year-old primigravida presented at 25 weeks of gestation for threatened preterm labour. Transabdominal ultrasound revealed an echogenic mass on the placenta measuring 8.7 × 4.4 cm. Following a successful tocolysis and administration of a course of antenatal corticosteroids, she was discharged home. At 27 weeks of gestation, she developed a second episode of preterm contractions. Besides, the foetus was found to be small for gestational age. In the second episode of preterm contractions, intravenous magnesium sulfate infusion was commenced for foetal neuroprotection. Tocolysis was commenced for severe prematurity. She went into spontaneous preterm labour. Placenta examination revealed multiple solid masses with fleshy and congested dark red surface. A histopathological examination of the placenta confirmed the diagnosis of chorangiomas. The baby was discharged in good condition at 5 months of age. Placental chorangiomas, notably when they are multiple and large in size, are associated with adverse pregnancy outcomes. Therefore, close antenatal surveillance is necessary to allow timely recognition and intervention of pregnancy complications. Our case portrays an unexpected favourable neonatal outcome associated with a giant chorangiomas.
The use of atosiban prolongs pregnancy in patients treated with fetoscopic endotracheal occlusion (FETO)
Authors: Kosinski Przemyslaw , Luterek Katarzyna , Lipa Michal , Wielgos Miroslaw
Published: October 2019

Objective

To evaluate the impact of atosiban as a tocolytic agent in patients treated with the fetoscopic endotracheal occlusion (FETO) procedure due to congenital diaphragmatic hernia (CDH). As premature birth after fetoscopy remains a serious concern, an effort to reduce prematurity is required.

Methods

A total of 43 patients with severe CDH treated with FETO were enrolled in this study. The study group consisted of 22 patients who received atosiban during the FETO procedure and a control group of 21 patients who did not receive atosiban during the FETO procedure. Demographic data, gestational age (GA) at delivery, cervical length and GA at premature rupture of membranes (PROM) were evaluated.

Results

The GA at delivery was significantly different between the two groups studied. The median GA at delivery was 32.6 and 34.5 weeks in the no-atosiban vs. atosiban groups, respectively (P = 0.013). The median cervical length was 29.9 and 31.2 mm for the no-atosiban and atosiban groups, respectively, and was not statistically significant (P = 0.28). There were no significant correlations between groups for the occurrence of PROM, GA at the time of PROM, duration of the procedures, parity, maternal body mass index (BMI) or age. In the univariate linear regression model, the only factor independently associated with GA at delivery was the use of atosiban during FETO procedures (β = 0.375; P < 0.013).

Conclusion

In cases of severe CDH treated with FETO, the use of atosiban as a tocolytic agent during the procedure prolonged pregnancy by 2 weeks. Cervical length, duration of FETO or maternal characteristics were not associated with GA at delivery.
Identification and characterization of novel short-type BmPGRP-S4 from the silkworm, Bombyx mori, involved in innate immunity
Authors: Wang Qiang , Ren Meijia , Liu Xiaoyong , Xia Hengchuan , Chen Keping
Published: October 2019

Peptidoglycan recognition proteins (PGRPs) are pattern recognition receptors that can recognize bacterial peptidoglycans and trigger the innate immune response of insects. Here, we identified and characterized a novel short-type Bombyx mori peptidoglycan recognition proteins short-4 (BmPGRP-S4) in a lepidopteran insect, Bombyx mori. BmPGRP-S4 exhibited a cDNA sequence length of 600 bp, encoding 199 aa with a protein molecular weight of 22 kDa. Multiple sequence alignment revealed that BmPGRP-S4 contains a conserved PGRP domain. Quantitative real-time polymerase chain reaction analysis showed that BmPGRP-S4 is highly expressed in the early developmental stages of silkworm larvae and presents tissue-specific expression in hemocytes. Interestingly, BmPGRP-S4 expression is significantly induced by bacterial infection in the midgut, fat body, and hemocytes. Furthermore, a dual luciferase reporter gene assay revealed that BmPGRP-S4 can activate the expression of the antimicrobial peptide genes lebocin, moricin, cecropin D, cecropin B, and attacin. Taken together, these results suggest that BmPGRP-S4 plays an important role in the innate immune response of silkworms.

Authors: Clark Lauren , Ribéreau-Gayon Agathe , Sotiriou Mina , Standen Alex , Thorogood Joe , Tong Vincent C.H.
Published: October 2019

This case study presents an ambitious student-staff partnership project at University College London (UCL) to publish a collaborative book on higher education pedagogy. Over two-and-a-half years, a total of 86 students and staff contributed to the project, which sought to provide educators with a new type of scholarly material under the unifying theme of connecting research and teaching. Multiple layers of student-staff partnership were interwoven throughout the project; this case study contextualizes these layers against three dimensions: institutional, organizational, and community identity. Central to the project was our distinctive approach to engaging with Graduate Teaching Assistants (GTAs) and their crucial role in bringing the three dimensions together. As such, the project represents a model of enhanced student-staff partnership that has the capacity to empower students and break down educational silos to form new, multi-specialty learning communities.
Students as contested: Exploring issues of student identity and identification in educational spaces
Authors: Kenway Ashley , Wilkinson Phil , Dowden-Smith Kieron
Published: October 2019

This article explores issues of student identity and identification through a third-space theory lens. In addition, it positions this use of third-space theory as contributory to Students-as-Partners (SaP) approaches to teaching and learning. Naturally, this research was constructed as a SaP project, and research was undertaken as a collaboration between two undergraduate students and their lecturer. The literature review and student interviews presented here were conducted by the student co-researchers and interviews involved their BSc Cyber Security Management peers. These interviews unpacked constructions of student identity, student-lecturer relationships, and professional experiences. Thematic analysis of these interviews is presented reflectively with reference to student and lecturer perspectives. Finally, this article argues that for SaP to be successful it is necessary to critically examine the “student” identifier.
A co-creation of learning and teaching typology: What kind of co-creation are you planning or doing?
Authors: Bovill Catherine
Published: October 2019

In higher education discourse, reference to co-creation, partnership, and student engagement (to name but a few of the commonly used terms), covers a very wide range of different research and practice. This variety can often be confusing. In response, I present a co-creation oflearning and teaching typology, which is a practical resource intended to support students and staff to reflect on, and discuss, their planned and current practice and to be able to identify what particular kind of co-creation they are planning or doing. The typology can be used individually, in small groups or at an institutional level. It has been designed to be adaptable and includes space for additional co-creation variables and responses to be added. Informal feedback from using the typology suggests it has the potential to be (a) a planning tool, (b) a reflective tool, and (c) a mapping tool.
A Scoping Review on Integrating Inorganic Nanomaterials into Cement Composites
Authors: Mahinroosta Mostafa , Allahverdi Ali
Published: October 2019

Today, nanomaterials have gained tremendous attention in various engineering fields. The prominent physicochemical properties of nanomaterials have made them promising and interesting options for application in construction and building materials. These applications range from structural reinforcement for development of cement composites with outstanding and multifunctional characteristics to production of self-compacting and self-cleaning materials. The incorporation of nanomaterials in cement composites leads to the enhancement of their physicomechanical properties and the induction of superior durability performance. The addition of nanomaterials diminish the formation of micropores by acting as a filling agent, generating a very compact and uniform matrix and automatically decreasing the growth of micropores in the matrix. Moreover, nanomaterials have great potential in diminishing the transport properties. It will also be demonstrated in this article that the strength gain of cement composites is directly associated with the packing and nucleation effect of nanomaterials. Within the scope of the current comprehensive review, general information and definitions of cement composites and nanotechnology are first elucidated. Then, the nanosized additives that greatly improve the characteristics of cement composites, such as nanosilica, nanoalumina, nano–titanium dioxide, nano–iron oxides, nano–zinc oxides, nano–magnesium oxide, and nano–copper oxide are discussed. Furthermore, the most important challenges and problems in the use of nanomaterials in cement composites are presented. The time scope placed on the review is from 2010 to early 2019.
Crossing the Pacific
Authors: Yang Daqing
Published: October 2019

In mediating the human experience of space, communications technologies played an important role along with means of transportation. When wireless telegraphy was introduced to Japan around the turn of the twentieth century, it was not just the military that made successful use of the incipient technology. The adoption of shipboard wireless telegraphy in trans-Pacific navigation helped reshape the Japanese spatial experience of the world’s largest ocean, thanks to extensive coverage by Japanese newspapers. However, technology never marches forward in a straight line as many published histories of wireless telegraphy suggest. The lack of inter-continental wireless telegraphy contributed to communication congestion across the Pacific during World War I, forcing the Japanese government to relax its monopoly while the Japanese business community abandoned its endeavor to build new trans-Pacific submarine cables in favor of wireless telegraphy. By the early 1930s, this public-private partnership enabled Japan to become a major player in international wireless telegraphy which dominated trans-Pacific communication. This article demonstrates that space and technology became mutually constitutive so that the Pacific Ocean could best be described as a single spatial-technological construct.

Neste trabalho, defendemos que não se pode escapar da variação radical (REZENDE, 2000; 2008; 2014) que fundamenta a identidade das formas linguísticas. Com o objetivo de apreender o funcionamento dinâmico das unidades na prática de produção e reconhecimento de enunciados, simulamos uma situação enunciativa entre sujeitos e, manuseando as unidades morfolexicais um, o e cachorro dos enunciados do diálogo de partida, segundo os pressupostos da Teoria das Operações Predicativas e Enunciativas, formalizamos o funcionamento dessas formas no processo de determinação nominal. Para tanto, explicitamos invariantes de base e reafirmamos a sua importância para a sustentação quer dos valores construídos em língua quer da apropriação desses valores peelos sujeitos. Com efeito, esperamos ter contribuído para a compreensão de que, de um ponto de vista enunciativo, a identidade das formas linguísticas é o construto de uma prática (trabalho), que articula uma invariante de base com a diversidade linguística e experiencial.

Published: October 2019

An ultra-performance liquid chromatography–tandem mass spectrometry (UPLC–MS/MS) method was established to determine ebeiedinone in mouse blood, and the pharmacokinetics of ebeiedinone after intravenous (0.5 mg/kg) and oral (2, 4, and 8 mg/kg) administration was studied. Twenty-four mice were randomly divided into 4 groups, 1 group was for intravenous administration (0.5 mg/kg), and other 3 groups were for oral administration (2, 4, and 8 mg/kg), with 6 rats in each group. Yubeinine was used as an internal standard. Multiple reaction monitoring (MRM) mode was used to quantitatively analyzed ebeiedinone m/z 414.4 → 91.1 and the internal standard m/z 430.4 → 412.3 in the electrospray ionization (ESI) positive interface. In the concentration range of 1–2000 ng/mL, the ebeiedinone in the mouse blood was linear (r2 > 0.995), and the lower limit of quantification was 1.0 ng/mL. In the mouse blood, the intra-day precision coefficient of variation (CV) was less than 15%, and the inter-day precision CV was less than 15%. The accuracy ranged from 85.4% to 114.6%, and the average recovery was higher than 61.3%. The matrix effect was between 87.0% and 106.5%. These data met the pharmacokinetic study requirements of ebeiedinone. The UPLC–MS/MS method was sensitive, rapid, and selective and was successfully applied to the pharmacokinetic study of ebeiedinone in mice. The absolute bioavailability of ebeiedinone was 30.6%.
GENDER STRATEGIES AND POLITICAL LEADERSHIP
Authors: Khamitov N. V. , Dandekar D. D.
Published: October 2019

Purpose. The purpose of the article is to understand the issue of gender strategies of political leadership. Theoretical basis. The works of Ukrainian and foreign scholars helped to find out the specifics of male and female leadership. The article applied the latest methodology of androgyny-analysis. According to this methodology, sex has not only a biological, psychological and social, but also an existential dimension. So, the existential dimension of gender is soulfulness as an existential femininity and spirituality as an existential masculinity. These two beginnings may conflict and may be in harmony. Depending on this, we have constructive or destructive strategies for the development of both the personality and the relations between individuals. Constructiveness here means not only gender equality, but also gender partnership. Originality. In the context of modern gender anthropology and androgyny-analysis, it is found that as a result of the implementation of the strategy of existential sexism and existential hermaphroditism, political leadership becomes authoritarian, and sometimes also totalitarian, while the strategy of androgynism associated with gender partnership gives rise to constructive political leadership. Conclusions. Androgynous personality of a political leader, which balances the existential and psychological qualities of men and women, is able to reform the society and change the country for better.
GENDER ASPECTS OF RELATIONSHIP IN THE SYSTEM OF MANAGEMENT

Published: October 2019

Purpose. The purpose of this paper is the study of gender aspects of management and relationship between management characteristic and style of leadership from gender typing in order to improve management efficiency. Theoretical basis. To understand the influence of gender mechanisms on the organization’s governance system, it turns out that there is a difference in the approach of women and men to management and leadership. The main characteristics of male and female leadership style, features in making management decisions regarding work and career are given. Originality of a paper is the further development in the theory of gender processes with application of interdisciplinary approaches in studying the phenomenon of gender, not from the point of view of the interactions between two large social groups (men and women), but as a social resource of an organization where men and women represent labor potential, rational use of which is the key to successful management in the organization. The social potential of Ukrainian women can become a valuable resource in a country, a region, and any social organization. Conclusions. In modern society, the unique experience of women’s rule is ignored, indicating that they have significant and little used management potential. An analysis of gender interactions in management processes revealed the active desire of women for career growth and success in individual image. However, the transformation of the gender sphere in an organization reflects the preference of patriarchal relations, which is an obstacle to the advancement of women in the managerial structure and, accordingly, requires them to make significant efforts to achieve equal management opportunities with men. To ensure the effectiveness of the organization, it is necessary to take into account the gender factor and comply with gender balance in management positions.
Evaluation of proposed integrated diseases management strategies in blackberry cultivation according to its sustainability
Authors: Narváez Yimmy Alexander Zapata , Beltrán-Acosta Camilo Rubén
Published: October 2019

Abstract The production of blackberry in Colombia is a source of income and rural employment in 18 departments; however, the plant is affected by diseases such as gray mold, anthracnose and powdery mildew that can cause losses of up to 70%. The control of these diseases is mainly carried out with chemical fungicides such as benomyl, carbendazim and mancozeb applied every 7 or 15 days. Nevertheless, being a continuous fructification plant of weekly harvest, the proximity between the application of the pesticides, the harvest, and its consumption represents a health risk due to the residually of these molecules, condition that affects its innocuousness and sustainability. Accordingly, this work aimed to develop an integrated management strategy for these diseases. Two strategies were proposed integrating agricultural labors with applications of Tricotec®-Kendal® or Tricotec®-EcoSwing®, and three fungicides applied according to the incidence of each disease, compared with the diseases producer management. In 77 evaluation days the effectiveness of the strategies was assessed according diseases incidence reduction, on fruit production, environmental impact, using the environmental impact quotient in the field (EIQf), and the reduction of fruit pesticides residues. According to the results obtained, the strategy Tricotec®-Kendal® with applications of a fungicide based on azoxystrobin + difeconazole showed the lowest diseases incidence, averaging 3% for gray mold, 11% for anthracnose, and 21% for powdery mildew and the highest amount of fruit harvested averaging 5,668 g. The strategy showed the lowest EIQf (5.3) compared with a value of 81.50 obtained with the traditional producer management, as well as the least amount of pesticides residues, corresponding to azoxystrobin (0.10 mg/kg) and difeconazole (0.046 mg/kg); these, however, remained within the maximum residue limits for pesticides stated by the European Union for blackberry.

Published: October 2019

Abstract In order to test the use of ammonia thiosulfate (ATS) in the chemical thinning of the Japanese plum tree, a field experiment was conducted throughout the 2015/2016 and 2016/2017 crop growing seasons at Ponta Grossa, PR, Brazil. The experimental design adopted herein was a randomized block design (RBD). During the 2015/2016 season, the trial was comprised of two accesses and six treatments, such as T1 (control); T2 (ATS 4%); T3 (ATS 5%); T4 (ATS 6%); T5 (ATS 7%) and T6 (manual thinning) with four replications. During the 2016/2017 season, solely one plum tree access was taken into account along with six treatments, such as T1 (control); T2 (ATS 6%); T3 (ATS 7%); T4 (ATS 8%); T5 (ATS 9%) and T6 (manual thinning) and four replications. The evaluations were performed seven days before the application of ATS and 30 days before harvest to establish the percentage of fruit drop. The following response variables were assessed: diameter (D), fresh mass (MF), firmness (N), soluble solids (SS), titratable acidity (AT), ratio, pH and plant production (PP). Experimental data were compared by means of the Tukey test at 5% probability. The concentration of 8 % ATS was efficient in the chemical thinning of the Japanese plum fruits, having a diameter and productivity similar to the manual thinning, evidencing that such a product was amenable to enhance commercial fruit quality.

Published: October 2019

Resumo O objetivo deste artigo é analisar aspectos da formação econômica de Mato Grosso do Sul (MS). Em termos teóricos, admite-se que o desenvolvimento do estado de MS é historicamente dependente dos ciclos externos (nacionais e internacionais) e que, por isso, a sua trajetória de desenvolvimento tem traços marcantes de uma inserção periférica. Portanto, propõem-se uma análise integrada que leva em consideração uma orientação teórica mais geral, vinculada ao pensamento de grandes intérpretes brasileiros como Caio Prado Jr. e Celso Furtado e, também, uma análise que leva em consideração o protagonismo e as especificidades locais. As conclusões apontam que, voluntária ou involuntariamente, a incorporação do Estado ocorreu em termos periféricos, sendo a ele incumbido o papel de ser um dos “celeiros” do Brasil.
Aspectos institucionais da formação de preços
Authors: Andrade Rogerio P. de , Palludeto Alex Wilhans Antonio
Published: October 2019

Resumo De acordo com a visão tradicional do processo de formação de preços, estes resultam das interações entre oferta e demanda. Um preço de equilíbrio é aquele no qual as quantidades demandadas se igualam às quantidades ofertadas. O sistema de preços fornece um mecanismo por meio do qual mudanças nas condições de oferta e demanda condicionam a eficiência alocativa dos recursos. No entanto, em grande medida, os preços não são determinados no mercado pela oferta e demanda nessa acepção estrita, mas por outros fatores como poder, estruturas de mercado, convenções, regras, rotinas etc. O propósito deste artigo é investigar o papel e a influência de uma variedade de instituições no processo de formação de preços, com particular ênfase nas convenções.
Uma análise do dilema da persistência da inflação de serviços no Brasil

Published: October 2019

Resumo Este artigo analisa o Dilema da Persistência da Inflação de Serviços no Brasil, para o período entre agosto de 1999 e fevereiro de 2017. Para efeitos de comparação, cálculos também são feitos para o IPCA, para a inflação desagregada de bens, além de alguns itens desagregados da própria cesta de serviços. São utilizados modelos ARFIMA, assim como testes para verificação de quebras estruturais. Os resultados mostram que, a princípio, a persistência na inflação de serviços é maior que a encontrada no IPCA e nos preços de bens. No entanto, após o tratamento das quebras estruturais, a variação dos preços dos serviços se mostra antipersistente e estacionária, indicando a existência do Dilema da Persistência da Inflação de Serviços para o caso brasileiro. O mesmo comportamento se verifica para os principais itens componentes da cesta de serviços.
Emissões de gases de efeito estufa e eficiência ambiental no Brasil
Authors: Soares Thiago Costa , Cunha Dênis Antônio da
Published: October 2019

Resumo Este artigo tem como objetivo analisar a eficiência ambiental dos municípios brasileiros e relacioná-la a um conjunto de características socioeconômicas locais, controlando aspectos como heterogeneidade tecnológica e dependência espacial. Para tanto, utilizou-se o método de Análise Envoltória de Dados (DEA) Metafrontier para construir o indicador, que foi baseado nas emissões de gases de efeito estufa. Em seguida, ajustou-se um modelo que relaciona eficiência ambiental, características socioeconômicas e dependência espacial (Spatial Autoregressive Model). Os principais resultados revelaram que renda per capita e IDH se relacionaram positivamente com o indicador de eficiência. Por outro lado, as variáveis desigualdade e educação mostraram relação negativa com o índice. Ademais, houve evidências de efeito “spillover ambiental” entre municípios, indicando que a criação de práticas sustentáveis em âmbito local pode produzir externalidades positivas regionalmente.
La iniciativa BRICS y China: entre la emergencia y la irrelevancia
Authors: Vadell Javier
Published: October 2019

Resumen El objetivo de este artículo es analizar los BRICS a partir de una perspectiva crítica. El trabajo comienza presentando el surgimiento de los BRICS como una “formación económica e política” según las teorías tradicionales de las RRII y de la EPI . Las preguntas principales son: ¿en qué medida los BRICS desafían el orden liberal Occidental? ¿de qué manera este cambio afecta el desarrollo y la inserción global de los países periféricos? Nuestra hipótesis es que el proceso de fortalecimento institucional de los BRICS y la possibilidad de expansión hacia un BRICS plus no es un acontecimiento aislado. Es decir, no se puede interpretar los BRICS sin considerar el rol de liderazgo de China en el establecimiento de nuevas instituiciones globales, que implican en cambios en la hegemonía global

Published: October 2019

Abstract Lean production aims at operational improvement by the elimination of waste and variability reduction. The lean practice known as help chain, which contributes to the lean goals is an underexplored topic. Thus, the objective of this paper is to propose guidelines regarding the help chain design and operation by addressing issues related to the definition of the events that need support from the chain and selection of the members to be involved. The proposed guidelines involve seven steps: (i) delimitation and evaluation of the scenario of application; (ii) identification and classification of abnormalities; (iii) identification of the types and contents of visual devices; (iv) identification of agents involved in the help chain; (v) definition of the operating logic of the help chain; (vi) training and qualification; and (vii) application and evaluation of the results. A partial application in the printing department of a tobacco’s manufacturer plant is a basis for discussing the strengths and weaknesses of the guidelines.

Este estudo teve como objetivo avaliar variáveis de manejo que possam constituir fatores de risco da infecção por BoHV-1 e/ou por BVDV em rebanhos leiteiros com histórico de problemas da reprodução em vacas mestiças em manejo extensivo e sem histórico de vacinação prévia para o controle de IBR e BVD. Anticorpos neutralizantes anti-BoHV-1, anti-BVDV e para ambos os vírus simultaneamente foram identificados em 62,5% (165/264), 45,1% (119/264) e 31,4% (83/264), respectivamente, das amostras analisadas. Os fatores de risco associados à infecção por BoHV-1 foram rebanhos com número total de fêmeas superior a 100, presença de ordenha mecânica, não utilização de inseminação artificial na reprodução e a compra infrequente de animais. Para BVDV, os fatores de risco foram aptidão mista (leite/corte) do rebanho, presença de ordenha mecânica, ausência de quarentena para os animais recém-adquiridos, presença de piquete de parição e a não utilização de inseminação artificial. Para a infecção simultânea (BoHV-1/BVDV), a presença de ordenha mecânica aumentou o risco em 3,36 vezes, e o uso de inseminação artificial reduziu em 56% o risco de infecção nos rebanhos avaliados.

ABSTRACT A retrospective and cross-sectional study of canine tumors was performed in the capital of State of Mexico from 2002-2016. Since then, 393 tumors were remitted. Descriptive epidemiology was made from all data: breed, age, sex, and tumor features. Then the risk association between cutaneous and non-cutaneous tumors with variables such as sex, breed, and age were analyzed through an exact Fisher test and Odds ratio. In addition, some characteristics of the canine population were studied under a survey. Of all tumors, skin tumors were the most frequent (59.0%). The group of tumors related to ultraviolet radiation was the most common (15.1%). The frequency of tumors in females was 53%, nevertheless, males had more risk to develop cutaneous tumors (OR=1.88, 1.24-2.84) (0.003). The Pure breeds were the most common (82.5%) and the most frequent age range was > 7 years (54.7%). The survey showed that males (53%) and the age range 1-7 years (62.1%) were the most frequent. Conclusions, age, breed, and sex were identified as the major risk factors for tumorigenesis. Likewise, skin tumors were associated with exposure to ultraviolet radiation, probably to the height of the locality (2667mamls).

RESUMO Avaliou-se a incidência da miopatia White Striping (WS) em três linhagens de frangos de corte machos e suas consequências sobre a composição química e a qualidade física da carne. Para determinação das porcentagens de incidência dos diferentes graus da miopatia WS (normal, moderada e severa) nas linhagens, foi utilizado um delineamento inteiramente ao acaso (DIC), com três tratamentos (linhagens A, B e C) e cinco repetições de 300 peitos cada. Para as variáveis químicas e físicas, utilizou-se um DIC em esquema fatorial 3 x 3 (três linhagens x três níveis de WS), com 15 repetições cada. Os dados foram submetidos à análise de variância e, em casos de diferenças significativas, utilizou-se o teste de Tukey (P≤0,05). As aves da linhagem A apresentaram 84,81% de peitos classificados como normais e 9,91% de peitos classificados como moderados, valores respectivamente maiores e menores que nas duas demais linhagens. Os peitos classificados com miopatia WS severa foram mais pesados e apresentaram maiores porcentagens de lipídios e umidade, e menor concentração de proteína bruta. As concentrações de colágeno total, termo solúvel e insolúvel variaram com o nível de acometimento por WS nos filés, com comportamento específico para cada linhagem.

ABSTRACT The aim of this study was to characterize the tissue reactions triggered by the polypropylene mesh coated with chitosan and polyethylene glycol film, and if it’s able to prevent the formation of peritoneal adhesions. Defects in the abdominal wall of rats were induced and polypropylene meshes coated with chitosan/polyethylene glycol (CPEG group, n= 12) and uncoated (PP control group, n= 12) were implanted. On the fourth and forty-fifth postoperative day the formation of adhesion and the tissue reaction to the biomaterial was evaluated through histological and histochemical analysis. The area (P= 0.01) and severity (P= 0.002) of the adhesion was significatively less in the CPEG group. On the fourth day the foreign body reaction was less intense in CPEG group (P= 0.018) and the production of collagen fibers was more intense in this group (P= 0.041). The tissue reactions caused by the biomaterials were similar on the 45th day, with the exception of the high organization of collagen fibers in the CPEG group. The CPEG meshes did not fully prevent the formation of adhesions, but minimized the severity of the process. The foreign body reaction promoted by polypropylene meshes coated with CPEG is less intense than that triggered by uncoated polypropylene meshes.

SUMMARY OBJECTIVE In this study, we aimed to analyze the relationship between serum uric acid (UA) and microalbuminuria as a marker of renal injury in type 2 diabetes mellitus. METHODS A total of 100 patients with type 2 diabetes mellitus were enrolled in the study. Participants were divided into two groups according to the urinary microalbumin/creatinine ratio: diabetic nephropathy and non-nephropathy group. UA and microalbuminuria were compared between the study groups. RESULTS Serum UA levels of diabetic nephropathy patients were significantly higher than those in the non-nephropathy group (UA in patients with diabetic nephropathy groups: 6.3 (1.82) mg/dl, UA in patients of the non-nephropathic group: 4.85 (1.92) mg/dl) (p<0.001). There was a correlation between microalbuminuria and UA (r=0.238). This correlation was statistically significant (p=0.017). CONCLUSION UA levels may be an important predictor of nephropathy in diabetic patients.

SUMMARY INTRODUCTION Teenage pregnancy is a universal phenomenon, with higher prevalence in developing countries. Although there has been a reduction in Brasil since the year 2000, the age-specific fertility rate for this age group remains high. OBJECTIVE To evaluate the frequency of adolescence pregnancy in in Brasil from 2006 to 2015 and its association with the Human Development Index (HDI). METHODS A descriptive epidemiological study, conducted by searching the database of the Department of Informatics of the Unified Health System (DATASUS), using information from the Information System on Live Births (SINASC) for the five Brazilian regions. RESULTS There was a reduction in the percentage of live births (LB) from adolescent mothers (10 to 19 years old) in Brasil by 13.0% over the last ten years. This decline was observed in all Brazilian regions among mothers aged 15 to 19 years. The number of LB increased by 5.0% among mothers aged 10 to 14 years in the North and decreased in the other regions, with higher rates in the South (18.0%). The specific fertility rate for the 15-19-year-old group decreased from 70.9/1,000 to 61.8/1,000 in the period. The proportion of LB is inversely associated with the HDI, except in the Northeast (the lowest HDI in the country), where there was a significant reduction (18.0%) among mothers aged 15-19 and 2% among those aged 10-14 years. CONCLUSION Teenage pregnancy in Brasil is in slow decline, especially among mothers aged 10-14 years and is inversely associated with the HDI, except in the Northeast.

ABSTRACT Objective: to evaluate the effectiveness of auricular therapy on pain in the active phase of labor. Method: a randomized, parallel and triple-blind clinical trial, conducted from April 2015 to June 2016. A total of 102 pregnant women with a gestational age ≥37 weeks, cervical dilatation ≥4 cm and two or more contractions within 10 minutes, randomly divided into three groups: intervention (auricular therapy), placebo (sham points) and control (without intervention). Auricular therapy was applied with crystal microspheres in four strategic points and pain intensity evaluated by a Visual and Analog Scale. For the analyses, the following tests were used: Kruskal-Wallis and Generalized estimating equations. Results: pain intensity averages were similar at admission (intervention: 7.2±1.6 vs placebo: 6.9±2.4 vs control: 7.5±1.8; p-value=0.4475), but with 60 minutes (intervention: 6.8±1.9 vs placebo: 7.5±2.4 vs control: 8.3±1.8; p=0.0060) and 120 minutes (intervention: 7.1±1.9 vs placebo: 8.0±2.4 vs control: 8.8±1.9; p-value=0.039), there was a significant increase in pain scores between parturients of the placebo and control groups. Conclusion: parturients who received auricular therapy during labor showed a reduction in pain intensity, which may characterize the effectiveness of the therapy in this phase.

Resumo Objetivo Comparar o crescimento de recém-nascidos prematuros de muito baixo peso internados na Unidade de Terapia Intensiva Neonatal, alimentados com LHP e LHP acrescido de suplemento comercial. Métodos Trata-se de uma série de casos, com delineamento longitudinal. População e amostra composta por todos os prontuários de RNPTMBP com menos de 36 semanas de idade gestacional e peso menor que 1.500g que responderam aos seguintes critérios de inclusão: clinicamente estáveis, de qualquer sexo, em uso de qualquer tipo de sonda pelo qual receberam leite humano pasteurizado e/ou que receberam leite humano pasteurizado com aditivo de fortificante comercial FM85®, e, que não apresentavam patologias que pudessem interferir no crescimento e ganho de peso. A partir do levantamento, constituiu-se dois grupos: recém-nascidos pré-termo de muito baixo peso que receberam leite humano pasteurizado (Grupo A) e os que receberam leite humano pasteurizado acrescido de FM85® (Grupo B). Resultados verificou-se que não houve diferença estatisticamente significativa entre os recém-nascidos pré-termo de muito baixo peso avaliados na comparação entre os dois grupos e entre o grupo analisado em dois momentos com as diferentes dietas. Observou-se, que a idade gestacional influenciou no ganho de peso diário em ambas as comparações. Conclusão Concluiu-se que as duas dietas utilizadas não implicaram em diferença estatisticamente significativas no crescimento quando comparados os dois grupos.
