O estudo descreve o perfil epidemiol?gico das gestantes HIV+/aids no Rio Grande do Norte (RN) e no Brasil e analisa a qualidade dos dados dispon?veis no Sistema Nacional de Informa??o de Agravos de Notifica??o (SINAN). A qualidade dos dados dispon?veis foi avaliada segundo a completude dos registros, sendo classificada em excelente, regular e ruim. No estado do RN, avaliou ainda a presen?a de disson?ncia na notifica??o de gestantes e mulheres HIV+/aids entre os servi?os de Vigil?ncia Epidemiol?gica do RN e os dados dispon?veis no SINAN/DATASUS. Ademais, analisou o comportamento da s?rie hist?rica das gestantes HIV+/aids, no per?odo de 2000 a 2013, no Brasil, regi?es e unidades federativas, segundo ra?a/cor, realiza??o do pr?-natal, faixa et?ria e escolaridade. Para a an?lise da tend?ncia do coeficiente de gestantes HIV+/aids foi usado o m?todo de regress?o polinomial. Foram selecionados fatores contextuais relacionados com a epidemia e ap?s a realiza??o de uma regress?o linear m?ltipla, foram selecionados aqueles capazes de explicar o percentual de varia??o do coeficiente de gestantes HIV+/aids. No estado do RN, entre 2007 e 2014, os dados evidenciaram uma completude considerada excelente nas vari?veis s?cio demogr?ficas. J? para as vari?veis referentes ao pr?-natal e ao parto, variou de ruim a regular. Foi identificada disson?ncia na notifica??o de gestantes e mulheres HIV+/aids entre os servi?os de Vigil?ncia Epidemiol?gica do RN e os dados dispon?veis no SINAN/DATASUS. As gestantes HIV+/aids se caracterizaram por estarem na faixa et?ria reprodutiva, negras, escolaridade inferior a oito anos e residentes na zona urbana. No Brasil, no per?odo de 2000 a 2014, a maioria das vari?veis s?cio demogr?ficas obteve uma completude excelente, sendo regular para a maioria das vari?veis relacionadas ao pr?-natal e ao parto. Observou-se ainda que a epidemia tem um comportamento heterog?neo, seguindo uma tend?ncia crescente na maioria dos estados. Em rela??o ?s vari?veis ra?a/cor, realiza??o do pr?-natal, faixa et?ria e escolaridade, pode-se observar que as adolescentes que n?o fizeram pr?-natal, pretas e analfabetas tiveram um maior incremento m?dio anual no coeficiente de infec??o por HIV/aids. Entre os fatores contextuais quanto maior o n?mero de homens infectados por HIV maior foi o aumento no percentual de varia??o do coeficiente de infec??o de gestantes HIV+/aids. O incremento no IDHM e na Taxa de brancos/negros correspondeu a uma diminui??o no percentual de varia??o do coeficiente de infec??o de gestantes HIV+/aids. Conclui-se que os sistemas de informa??o embora permitam um conhecimento acerca das gestantes HIV+/aids, ? necess?rio otimizar a notifica??o dos casos, aumentar a completude e consequentemente a qualidade da informa??o produzida, seja em n?vel nacional, estadual ou municipal, diminuindo a disson?ncia entre os dados produzidos nesses tr?s n?veis. O perfil epidemiol?gico das gestantes HIV/aids reflete a vulnerabilidade social dessas mulheres, traduzido no incremento observado ao longo da s?rie hist?rica e nos fatores contextuais a ele correlacionados. / The epidemiological profile of HIV / AIDS infection in Brazil has undergone changes in recent years, the phenomenon known as feminization of the epidemic, characterized by the increase in the number of cases in women of childbearing age and consequent increase in the risk of vertical transmission. The study describes the epidemiological profile of HIV + / AIDS pregnant women in Rio Grande do Norte (RN) and Brazil and analyzes the quality of the data available in the National Information System for Notification Diseases (SINAN). The quality of the available data was evaluated according to the completeness of the records, being classified as excellent, fair and poor. In the state of the RN, it also evaluated the presence of dissonance in the notification of pregnant women and HIV + / AIDS women between the services of Epidemiological Surveillance of the RN and the data available in SINAN / DATASUS. In addition, it analyzed the behavior of the historical series of HIV + / AIDS pregnant women, from 2000 to 2013, in Brazil, regions and federative units, according to race / color, prenatal, age and schooling. For the analysis of the tendency of the coefficient of HIV + / AIDS pregnant women, the polynomial regression method was used. We selected contextual factors related to the epidemic and after multiple linear regression, we selected those capable of explaining the percentage of variation of the coefficient of HIV + / AIDS pregnant women. In the state of the RN, between 2007 and 2014, the data showed a completeness considered excellent in the socio-demographic variables. As for the variables related to prenatal care and delivery, it ranged from poor to regular. Dissonance was identified in the notification of pregnant women and HIV + / AIDS women between the services of Epidemiological Surveillance of the NB and the data available in SINAN / DATASUS. HIV + / HIV pregnant women were characterized by being in the reproductive age group, black, schooling less than eight years old and living in the urban area. In Brazil, from 2000 to 2014, most socio-demographic variables obtained excellent completeness, being regular for most variables related to prenatal and childbirth. It was also observed that the epidemic has a heterogeneous behavior, following a growing tendency in most states. In relation to the race / color, prenatal, age and schooling variables, it can be observed that adolescents who did not have prenatal, black and illiterate had a greater average annual increase in the coefficient of HIV / AIDS infection. Among the contextual factors, the higher the number of men infected with HIV, the greater the percentage of variation in the infection coefficient of HIV + / AIDS pregnant women. The increase in the HDI and the White / Black Rate corresponded to a decrease in the percentage of variation in the infection coefficient of HIV + / AIDS pregnant women. It is concluded that information systems, although they allow a knowledge about HIV + / AIDS pregnant women, it is necessary to optimize the notification of cases, increase the completeness and consequently the quality of the information produced, be it at the national, state or municipal level, reducing the dissonance Between the data produced at these three levels. The epidemiological profile of HIV / AIDS pregnant women reflects the social vulnerability of these women, reflected in the increase observed throughout the historical series and in contextual factors correlated to it.

Nesse sentido, foram criados os Cursos de Gradua??o em Sa?de Coletiva. Na Universidade Federal do Rio Grande do Norte (UFRN), esse curso ? denominado de Gest?o em Sistemas e Servi?os de Sa?de (GSSS). Esta pesquisa tem o objetivo de analisar como se d? a inser??o (espa?o, tempo e condicionantes) e a atua??o profissionais dos egressos do Curso de GSSS da UFRN, mais especificamente: identificar limites, potencialidades e estrat?gias na inser??o profissional dos egressos; identificar as atividades desenvolvidas pelos egressos no trabalho; analisar os desafios para os egressos no mundo do trabalho; analisar os condicionantes da forma??o desse Curso na inser??o e atua??o profissionais; e conhecer a vis?o das coordenadoras sobre a cria??o e forma??o do Curso de GSSS. O estudo se vincula ? no??o de pesquisadores implicados e ? reflexividade como corrente de pensamento da pesquisa. A produ??o dos dados ocorreu pela t?cnica de Grupo Focal e entrevista individual com roteiro semiestruturado, ambas realizadas com egressos concluintes do Curso nos per?odos de 2012.2, 2013.2 e 2014.2, sendo que tamb?m foram entrevistadas coordenadoras do referido Curso. Quanto ? inser??o, os desafios foram categorizados em: remunera??o; reconhecimento da profiss?o em Sa?de Coletiva; identidade profissional; e interfer?ncias pol?ticas. J? as potencialidades foram categorizadas em: forma??o; n?cleo de saber e pr?tica da Sa?de Coletiva; e o cen?rio da Secretaria Municipal de Sa?de do Natal; e as estrat?gias para inser??o s?o a??es de car?ter coletivo e individual que visam divulgar o Curso e seu profissional, bem como avan?ar na constru??o de uma nova profiss?o. Sobre a atua??o profissional, s?o descritas as atividades desenvolvidas no trabalho pelos egressos, estas est?o associadas ? linha de forma??o de Planejamento, Gest?o e Avalia??o em Sa?de. Essas atividades profissionais refor?am a ideia do Curso de GSSS em formar Gestores da Sa?de para atuarem nos servi?os e sistemas de sa?de. No entanto, consideramos que a atua??o de um generalista em Sa?de Coletiva ir? al?m dessa ?rea de atua??o. Os desafios na atua??o profissional dos novos sanitaristas aparecem como de car?ter estrutural do mundo do trabalho de outras profiss?es e foram categorizados em: rela??es de poder, cultura institucional e v?nculo empregat?cio, tais desafios influenciam na sa?de mental dos trabalhadores. Com rela??o ? influ?ncia da forma??o na inser??o profissional, destaca-se o Est?gio Curricular, visto que o aluno amplia seu conhecimento e d? visibilidade profissional a si pelo v?nculo com os demais profissionais. Ainda mais, os egressos trazem suas cr?ticas positivas e negativas da forma??o que influenciaram na atua??o profissional. Pela forma??o e pela atua??o profissional, os egressos do Curso de Sa?de Coletiva s?o novos sanitaristas com identidade diferenciada dos sanitaristas p?s-graduados oriundos de outras gradua??es. / The debates in the field of Public Health have claimed that SUS required a new strategic player to boost the changes not reached during the Sanitary Reform, since only the graduate training in the field for the practice of Public Health professionals was not enough. Accordingly, the Undergraduate Courses in Public Health were established. At the Federal University of Rio Grande do Norte (UFRN), this course is called Management in Health Systems and Services (GSSS, as per its acronym in Portuguese). This research is intended to analyze how the insertion (space, time and conditioning factors) and professional performance of newly-trained professionals from the GSSS Course at UFRN happen, more specifically: to identify limits, potentialities and strategies in the professional insertion of newly-trained professionals; to identify the activities developed by newly-trained professionals at work; to analyze the challenges for newly-trained professionals in the job market; to analyze the conditioning factors of this Course in the professional insertion and performance; and to know the viewpoint of coordinators about the establishment and training of the GSSS Course. This study is linked to the notion of researchers involved and to the reflexivity as a line of thought of research. The production of data took place through the Focal Group technique and individual interviews with a semi-structured script, both of which were conducted with newly-trained professionals of the Course in the periods of 2012.2, 2013.2 and 2014.2, being that coordinators of the aforementioned Course were also interviewed. Regarding the insertion, the challenges were categorized in: wage; recognition of the profession in Public Health; professional identity and political interference. Concerning the potentialities, they were categorized in: training; core of knowledge and practice of Public Health; and the scenario of the Municipal Health Department of Natal; and the strategies for insertion are actions of a collective and individual nature aimed at disseminating the Course and its professional, besides advancing in the construction of a new profession. As for the professional performance, the activities developed at work by the newly-trained professionals are described, which are associated with the training line of Planning, Management and Assessment in Health. These professional activities enhance the idea of the GSSS Course as it concerns the training of Health Managers to deal with health services and systems. Nevertheless, one can consider that the performance of a generalist in Public Health will go beyond this field of operation. The challenges for the professional performance of new Public Health professionals are displayed with a structural nature in the job market of other professions, and they were categorized in: power relations, institutional culture and employment bond, which are challenges that influence the mental health of workers. Regarding the influence of the training in the professional insertion, one can highlight the Curricular Internship, because the student expands his knowledge and gives professional visibility to himself by the bond with the other professionals. Furthermore, the newly-trained professionals bring their positive and negative criticism of the training that influenced their professional performance. Due to the training and professional performance, the newly-trained professionals of the Undergraduate Course in Public Health are new Public Health professionals with a differentiated identity in relation to the Public Health professionals graduated in Public Health and coming from other undergraduate courses.

Les plantes ne pouvant pas se déplacer sont continuellement soumises aux stress environnementaux. La blessure, l’un des stress les plus fréquents auxquels la plante est soumise, peut causer d’important dégâts et faciliter l’entrée de pathogène dans les tissus de la plante. Pour répondre efficacement à la blessure, la plante a développé des mécanismes lui permettant de guérir ses tissus endommagés et d’empêcher l’infection pathogène. Les stress environnementaux sont perçus grâce à la présence de récepteurs spécifiques activant des voies de signalisation qui, à terme, conduisent à la mise en place de réponses de défense. Les modules de MAPK, composés de 3 kinases (MAP3K, MAP2K et MAPK) activées en cascades, représentent d’importantes voies de signalisation impliquées en réponse à divers stress biotiques et abiotiques. Grâce aux approches de tests de phosphorylation in vitro très maîtrisées dans le groupe « Stress signaling », j’ai pu identifier un module MAPK impliquant la MAP2K MKK3 et les MAPKs du groupe C (MPK1, 2, 7 et 14) activé par la blessure. Les MAP3Ks du sous-clade III (MAP3K13 à 20) sont transcriptionnellement induites par divers stress ce qui semble être un mécanisme assez conservé. Certains membres du sous-clade III sont induits par la blessure et parmi eux la MAP3K14 semble avoir un rôle majeur en amont du module MKK3/MPK1-2-7-14. Enfin, j’ai pu montrer que l’acide jasmonique (JA), une phytohormone importante produite en réponse à la blessure, tient un rôle important en amont du module. Ce-dernier est également activé en réponse à l’insecte herbivore Spodoptera littoralis et au champignon nécrotrophe Botrytis cinerea. Dans le contexte de blessure par l’insecte herbivore, MKK3 semble réguler la production de deux phytohormones, le JA et l’Acide Salicylique (SA). / Plants are sessile organisms. They have to cope continuously with environmental stresses. Injury, one of the most frequent stress conditions that plants must face may cause harsh damages to the plant tissues and facilitate the entry of pathogens. Therefore, plants have evolved mechanisms to respond efficiently to wounding by healing damaged tissues and preventing further pathogen infection. Wounding is a complex stress which is perceived by specific receptors which activate signaling pathways leading to those responses. Mitogen-Activated Protein Kinases modules are composed of 3 kinases (MAP3K, MAP2K and MAPK) activated in cascade and represent important signaling pathways involved in response to various biotic and abiotic stresses as well as in developmental processes. During my Ph.D I identified a MAPK module activated 30 minutes after wounding and involving the MAP2K MKK3 acting upstream of C-group MAPKs MPK1-2-7-14. In the past, the laboratory has shown that this module is dependent on the transcriptional regulation of sub-clade III MAP3Ks (MAP3K13 to 20). Some were found induced by wounding and among them MAP3K14 seems to have an important role upstream MKK3/C-group MAPKs. Finally I was able to show that Jasmonic Acid (JA), a major phytohormone produced upon wounding and involved in the mediation of defense responses, was shown to have an important role upstream the MKK3/C-group MAPKs module. The module is also activated by the herbivore Spodoptera littoralis and the necrotrophic fungus Botrytis cinerea. Upon insect feeding, MKK3 negatively regulates JA and SA levels. My work helped to better understand stress signaling events occurring upon wounding.

[pt] A pandemia do Covid-19 mudou hábitos do consumidor, o distanciamento social e o lockdown motivaram as pessoas a buscarem formas mais convenientes e seguras para satisfazerem suas necessidades. Lojas físicas precisaram se adaptar ao online para seguir faturando e o e-commerce se desdobrou para atender a toda demanda de forma eficaz. A omnicanalidade, então, se tornou um tópico ainda mais relevante nos maiores varejistas do país. Essa integração de canais tornou-se necessária, para obter ganhos de produtividade, acelerar o crescimento e progredir na experiência e no relacionamento com o cliente. Sendo uma pesquisa de caráter exploratório, o objetivo deste estudo foi identificar os desafios da estratégia omnichannel implementada em um grande varejista brasileiro, a Americanas S.A.. A metodologia adotada foi o estudo de caso, com dados coletados através de: 1) entrevistas em profundidade com cinco gestores, utilizando roteiro semiestruturado, à luz do modelo de criação da experiência do cliente de Verhoef et al. (2009). e 2) arquivos e apresentações publicados pela empresa, notícias na imprensa e artigos sobre a companhia. Os principais resultados evidenciaram que, dentre os esforços de integração do online com o offline, empoderamento do cliente e conveniência são a essência do planejamento estratégico adotado pela empresa atualmente. / [en] The Covid-19 pandemic has changed consumer habits, social distancing and the lockdown have motivated people to seek more convenient and safer ways to satisfy their needs. Physical stores have adapted to online sales to move forward and e-commerce has progressed to meet demand effectively. Omnichannel, then, became an even more relevant topic in the largest retailers in the country. This channel integration has become necessary in order to obtain productivity gains, accelerate growth and progress in customer experience and relationships. Being an exploratory research, the objective of this study was to identify the challenges of the omnichannel strategy implemented in a large Brazilian retailer, Americanas S.A. The methodology adopted was the case study, with data collected through: 1) in-depth interviews with five managers, using a semi-structured script, in the light of Verhoef et al. (2009). and 2) files and presentations published by the company, press releases and articles about the company. The main results showed that, among the efforts to integrate online with offline, customer empowerment and convenience are the essence of the strategic planning adopted by the company today.
