Les liens entre le saint, son disciple ou son compagnon s’observent dans l’iconographie par la mise en scène d’une relation privilégiée. Fondée sur l’analyse d’un corpus d’œuvres produites entre le XIe et la fin du XVe siècle, majoritairement en France et en Italie, l’étude a la volonté de déterminer comment se sont exprimés les liens dans la filiation et la parenté spirituelle, construite autour d’une relation unissant les saints (grands saints de la chrétienté comme ceux honorés localement), à leurs disciples ou compagnons privilégiés. Depuis la naissance de la relation jusqu’à son aboutissement, elle détermine les fonctions respectives des personnages à la lumière de leur élection, de leurs actions et de leurs comportements. L’analyse s’interroge également sur la finalité du « discipulat » ou du compagnonnage et sur la représentation de la dimension affective entre les personnages. Rappelant le modèle christique et apostolique, la représentation de la relation est un thème distinct, dont l’analyse révèle l’importance d’un genre de parenté spirituelle souvent oublié. / The links between the saint, his disciple or his companion can be observed in the iconography by the representation of a privileged relation. Based on the analysis of a corpus of works produced between the 11th and the end of the 15th century, mainly produced in France and Italy, the study will determine how the links in the filiation and the spiritual relationship (built on a relation uniting Major saints of the Christendom, as to those honored locally, to their privileged disciples or companions) were expressed. Since the origin of the relation until outcome, the analysis determines the respective functions of the characters through the lens of their election, their actions and their behavior. The analysis also wonders about the purpose of the disciple-or companionship and about the representation of the emotional dimension between protagonists. Reminding the Christ and apostolic model, the representation of the relation is a different theme, which reveals the importance of a spiritual relationship often forgotten.

La recherche de solutions alternatives à l’usage de pesticides en production horticole est devenue une exigence de santé publique. Ainsi, l’introduction de plantes de service (PdS) est une méthode écologique qui peut contribuer à diminuer le recours à la lutte chimique contre Myzus persicae, le puceron vert du pêcher. L’intérêt de certaines de ces PdS réside dans leur capacité à perturber l’installation du puceron sur son hôte et/ou à diminuer ses performances grâce à l’émission des composés organiques volatils (COV). Cependant, un obstacle majeur à leur utilisation est que leur efficacité se limite à un périmètre restreint et que leur production olfactive est sensible à de nombreuses variables biotiques et abiotiques. Identifier les plantes les plus performantes, comprendre leur mode d’action et chercher à optimiser leur efficacité est donc une démarche propre à favoriser leur emploi en horticulture. L’analyse de l’environnement olfactif est une clé pour évaluer et comprendre les interactions PdS-plante hôte-puceron.Au laboratoire, un typage avec un olfactomètre en Y a permis de sélectionner deux PdS émettrices de mélanges de COV ayant un effet répulsif marqué sur M. persicae : le basilic (Ocimum basilicum) qui agit directement sur l’insecte, et l’œillet d’Inde (Tagetes patula) qui agit indirectement via la plante hôte. Ainsi, les COV émis par T. patula rendent la plante-hôte (le poivron, Capsicum annuum) répulsive. En effet, lors des tests de choix, les pucerons s’orientent vers les poivrons seuls mais évitent les COV émis par des poivrons précédemment mis en culture associée pendant 5 jours avec l’œillet d’inde. Deux composés, le (E)-β-farnésène (EBF) et l'eugénol ont de fortes propriétés répulsives envers M. persicae.Différents facteurs peuvent affecter l’efficacité répulsive de ces plantes (climat, conduite, génétique). Nous avons comparé les COV émis selon les espèces et les chémotypes et testé l’effet répulsif individuel des COV. Cet effet « génotype » a été examiné en étudiant le comportement olfactif de M. persicae en présence des COV individuels émis par différents clones de Romarin (Rosmarinus officinalis). Cinq composés sont répulsifs, l’acétate de bornyle, le camphre, l’α-terpinéol, le terpinène-4-ol et le géranyle acétone. Seul le clone de romarin Voltz Splindler s’est avéré répulsif, alors que les autres clones contiennent également ces 5 composés répulsifs mais dans des proportions différentes. On peut donc conclure que la présence de ces composés ne suffit pas à induire une perturbation du comportement olfactif du puceron et que la concentration, la proportion, voire l’association des COV présents dans les bouquets olfactifs libérés, sont à l’origine de ces résultats contrastés. Par la technique d’électropénétrographie (EPG), nous avons mis en évidence un deuxième effet des COV émis par O. basilicum au stade végétatif et par T. patula au stade floraison sur le puceron. Ils perturbent fortement son comportement alimentaire, en réduisant notamment la durée d’ingestion du phloème qui se traduit par une baisse des ressources nutritionnelles et aboutit à une diminution de sa fécondité. Un suivi de la fécondité sur organe détaché nous a permis de mettre en évidence l’importance du stade phénologique de la PdS sur la composition et l’efficacité du mélange olfactif libéré. Une dernière étape de mon travail a permis de confirmer dans des conditions de cultures sous tunnels, l’effet de COV émis par ces deux PdS sur la démographie de M. persicae liée à une baisse de sa fécondité.En conclusion, cette thèse a mis en évidence que les COV émis dans l’environnement d’une plante hôte par des plantes voisines peuvent fournir un service aux cultures en réduisant les performances de ravageurs tels que M. persicae. Nous avons montré que des variables comme le chémotype ou le stade phénologique de la PdS peuvent modifier son message olfactif et constituer un moyen d’optimiser ce service. / The search for alternatives to the use of pesticides in horticultural production has become a public health requirement. Thus, the introduction of Companion plants (CP) is an ecological method that can help reduce the use of chemical control against Myzus persicae, the green peach aphid. The interest of some of these CP lies in their ability to disturb the installation of the aphid on its host plant and/or to reduce its performance through the emission of volatile organic compounds (VOCs). However, a major obstacle to their use is that their effectiveness is limited to a limited scope and their olfactory production is sensitive to many biotic and abiotic variables. Identifying the most efficient plants, understanding their mode of action and seeking to optimize their effectiveness is therefore an appropriate approach to promote their use in horticulture. Olfactory environment analysis is a key to assessing and understanding CP-host plant -aphid interactions.In the laboratory, we selected with a Y-olfactometer two CP producing VOC mixtures with a marked repellent effect on M. persicae: basil (Ocimum basilicum) which acts directly on the insect, and french marigold (Tagetes patula) which acts indirectly via the host plant. Thus, the VOCs emitted by T. patula make the host plant (pepper, Capsicum annuum) repellent: during the choice tests, the aphids move towards the peppers alone but avoid the VOCs emitted by peppers previously grown intercropped for 5 days with the french marigold. Two compounds, (E)-β-farnesene (EBF) and eugenol have strong repellent properties against M. persicae.Different factors can affect the repellent effectiveness of these plants (climate, plant management, genetics). We compared the VOCs emitted by species and chemotypes and tested the individual repellent effect of VOCs. This "genotype" effect was examined by studying the olfactory behaviour of M. persicae in the presence of individual VOCs emitted by different clones of Rosemary (Rosmarinus officinalis). Five compounds are repellent, bornyl acetate, camphor, α-terpineol, terpinene-4-ol and geranyl acetone. Only the rosemary clone Voltz Splindler was found to be repellent, while the other clones also contain these 5 repellent compounds in varying proportions. It can therefore be concluded that the presence of these compounds is not sufficient to induce a disturbance of the aphid's olfactory behaviour and that the concentration, proportion or even association of VOCs present in the released olfactory bouquets are at the origin of these contrasting results. By the electropenetrography (EPG) technique, we have demonstrated a second effect of the VOCs emitted by O. basilicum in the vegetative stage and by T. patula in the flowering stage on the aphid. They strongly disrupt its feeding behaviour, in particular by reducing the duration of phloem ingestion, which results in a decrease in nutritional resources and leads to a decrease in its fertility. A fertility monitoring on detached organs has allowed us to highlight the importance of the phenological stage of the CP on the composition and efficacy of the olfactory mixture released. A final step in my work confirmed, under tunnel conditions, the effect of VOCs emitted by these two CP on the demographics of M. persicae due to a decrease in its fertility. In conclusion, this thesis highlighted that VOCs emitted into the environment of a host plant by neighbouring plants can provide a service to crops by reducing the performance of pests such as M. persicae. We have shown that variables such as chemotype or phenological stage of the CP can modify its olfactory message and provide a way to optimize this service. We have thus identified disruptive CP and VOCs repellent to M. persicae, the first step towards the development of the push component of a stimulodissuasive diversion strategy to reduce the use of synthetic pesticides against M. persicae.

O presente estudo visou determinar a prevalência de bactérias Gram-negativas produtoras de produzem b-lactamases de amplo espectro (ESBL) e resistência adquirida a quinolonas mediada por plasmídeos (PMQR) em animais de estimação, investigando o potencial papel destes hospedeiros como portadores assintomáticos. Em 2012, foram coletadas 216 amostras (fezes e saliva) de 108 animais de companhia (29 gatos e 79 cães) abrigados em casas de família, um centro de acolhimento de animais abandonados, e no Centro de Controle de Zoonoses da Cidade de São Paulo. Do total de cepas estudadas, 85% apresentaram fenótipo sugestivo de PMQR; enquanto que 62% dos isolados exibiram um fenótipo característico e sugestivo para produção de ESBL, sendo na sua maioria identificadas como E. coli. Dentre os isolados, 14 carregaram variantes do gene blaCTX-M, 9 foram positivos para o gene blaTEM, e 6 foram positivos para blaSHV. Em relação às cepas resistentes às Q/FQ, 56% (n= 43) foram positivas para a presença do gene qnr, o qual foi identificado em 11 espécies diferentes. Os resultados apresentados demostram que animais de companhia podem ser portadores assintomáticos de cepas produtoras de ESBL e PMQR. / The present study aimed to determine the prevalence of Gram-negative bacteria producing b-lactamases producing broad-spectrum (ESBL) and acquired resistance to quinolones mediated by plasmids (PMQR) in pets, investigating the potential role of these hosts as asymptomatic carriers. In 2012, 216 samples (feces and saliva) of 108 companion animals (29 cats and 79 dogs) housed in shelters or a Zoonosis Control Center were collected from São Paulo city. Of the total strains studied, 85% had a phenotype suggestive for PMQR; while 62 % of the isolates exhibited a characteristic phenotype and suggestive for ESBL-producing genes, with the most identified as E. coli. Among the isolates, 14 carried variants blaCTX -M gene 9 were positive for blaTEM gene, and 6 were positive for blaSHV. Regarding resistant Q/FQ isolates, 56% (n = 43) were positive for the presence of qnr gene, which was identified on 11 different species. The results presented demonstrate that pets can be asymptomatic carriers of ESBL producing strains and PMQR.

It was realized an investigation starting from a systemic referencial looking for to investigate the organization of the accompanion- mother's routine under integrative focus contemplating the environmental , social and psychological aspects in a public hospital of the municipal district of São Paulo. Three married mothers who had been accompanying their sons during the first intermission period in this hospital about 15 or 45 days participated this investigation. To the data collection a semi- structured interview was used focusing three axes: routine, instructions about her performance during the intermission and hospital rules, positive and negative aspects related to her presence together to her interned son identified for the mother. The data collection was accomplished in the hospital wards. From the analysis of the results it was possible to identify that: a) the mothers noticed and expressed in the interview about the changes provoked in their daily routine as abandonment of the work, of the domestic activities and familiar living starting from the admission; b) the subjects focused as positive aspect the participation in humanization programs offered by the hospital, as well as the psychology section and of the medical team work; c) as negative aspects were identified feelings of solitude and anguish during the internment. The data pointed for the psychologist's work relevance as space reserved for reception and opportunity to express feelings, doubts and hopes. Suggestions are presented for future researches and the relevance of studies of this population / O presente trabalho teve como objetivo investigar como a mãe-acompanhante organiza seu dia-a-dia dentro e fora do hospital durante a internação do filho. Foi realizada pesquisa qualitativa a partir de um referencial sistêmico, buscando investigar a organização do dia-a-dia da mãe-acompanhante sob enfoque integrativo contemplando os aspectos ambientais, sociais e psicológicos em um hospital público do município de São Paulo. Participaram três mães, casadas, que acompanhavam seus filhos durante o período de primeira internação neste hospital, variando entre 15 e 45 dias de permanência. Foi utilizada para a coleta de dados entrevista semiestruturada enfocando três eixos temáticos: rotina; instruções sobre sua atuação durante a internação e regras do hospital; aspectos positivos e negativos identificados pela mãe referentes a sua presença junto ao filho internado. A coleta de dados foi realizada nas enfermarias do hospital. A partir da análise dos resultados foi possível identificar que: a) as mães percebiam e expressavam na entrevista as mudanças provocadas em seu cotidiano como abandono do trabalho, das atividades domésticas e convívio familiar a partir da internação; b) os sujeitos destacavam a participação nos programas de humanização oferecidos pelo hospital como aspecto positivo, bem como o trabalho do setor de psicologia e da equipe médica; c) nos aspectos negativos foram identificados sentimentos de solidão e angústia durante a internação. Os dados apontaram para a relevância do trabalho do psicólogo como espaço destinado para acolhimento e oportunidade de expressão de sentimentos, dúvidas e esperanças. São apresentados sugestões para futuras pesquisas e a relevância de estudos dessa população

In Brazil, inclusion was influenced by ideals of education from Europe and the United States. In relation to rights for students with Autism Spectrum Disorder (ASD), the Berenice Piana Law presents a significant support figure in the process of inclusion of this audience, the specialized companion, as long as their need is proven. In the Federal District (FD), this support is provided by a teaching assistant which is a Volunteer Social Educator (VSE). Considering the VSE as a support for the educational inclusion of the student with ASD leads to the need to reflect on pedagogical policies and practices directed at them, due to the challenges education faces. Moreover, it is debatable whether the rights of these students are being guaranteed, since not even the federal legislation guarantees the profile of this aid figure. This being true, the scarcity of research related to the VSE in the realm of educational inclusion is detected. From a broader perspective, this research investigates the inclusive process of students with ASD in reverse integration classes of mainstream school, to discover relevant aspects about the role of volunteer social educator, order to promote the educational inclusion of this public. The research aimed to investigate whether the volunteer social educator's role in the classroom in the process of including the student with ASD contributes to the success of their school performance or corroborates a veiled exclusion. The methodology used was exploratory qualitative research. It is a multiple cases study with one unit of analysis. The sources of evidence used were document analysis, observations and interviews. The research participants were two teachers, two VSE, a director and an educational counselor from two mainstream schools of the FD public school system in which they studied children with ASD in reverse integration classes accompanied by VSE. Exclusion processes were identified in both cases, although the importance of this educational support is acknowledged. The research revealed the necessity of continuous work in relation to the formation of the VSE. The way in which district legislation is supplying the specialized companion, to which the TEA student is entitled, has not been sufficient to guarantee the right to learn from the whole individual formation perspective. / Nas últimas décadas, surgiram vários movimentos internacionais em prol de um sistema de ensino mais inclusivo e menos segregativo. No Brasil, a inclusão sofreu influências de ideais de educação advindas da Europa e dos Estados Unidos da América. Em relação aos direitos voltados aos estudantes com Transtorno do Espectro Autista (TEA), a Lei Berenice Piana apresenta uma figura de apoio significativa no processo de inclusão desse público, o acompanhante especializado, desde que a sua necessidade seja comprovada. No Distrito Federal (DF), esse apoio é suprido pelo Educador Social Voluntário (ESV). Ao se considerar o ESV como apoio à inclusão educacional do estudante com TEA leva à necessidade de refletir sobre políticas e práticas pedagógicas a ele direcionadas, em virtude dos desafios colocados à educação. Além disso, é discutível se os direitos desses estudantes estão sendo garantidos, posto que nem mesmo a legislação federal garante o do perfil dessa figura de auxílio. Diante disso, e constatada a escassez de pesquisas relacionadas ao ESV no âmbito da inclusão educacional, numa perspectiva mais abrangente, esta pesquisa investiga o processo inclusivo de estudantes com TEA em turmas de integração inversa de escola regular, para descobrir aspectos relevantes sobre o papel do educador social voluntário, a fim de promover a inclusão educacional desse público. A pesquisa teve por objetivo investigar se a atuação do educador social voluntário, em sala de aula, no processo de inclusão do estudante com TEA, contribui para o êxito de seu desempenho escolar ou corrobora uma exclusão velada. A metodologia utilizada foi a pesquisa qualitativa exploratória. Trata-se de um estudo de casos múltiplos com uma unidade de análise. As fontes de evidência utilizadas foram análise documental, observações e entrevistas. Os participantes da pesquisa foram dois professores, duas ESV, uma diretora e uma orientadora educacional de duas escolas regulares da rede pública de ensino do DF nas quais estudavam crianças com TEA em turmas de integração inversa acompanhados por ESV. Processos excludentes foram identificados nos dois casos, ainda que reconhecida a importância desse apoio educacional. A pesquisa concluiu ser necessário um trabalho contínuo de formação em relação ao ESV. A maneira como a legislação distrital está suprindo o acompanhante especializado, a que o estudante com TEA tem direito, não tem sido suficiente para garantir os direitos de aprendizagem da perspectiva da formação integral.

Les structures de l’Economie sociale et solidaire ont développé des relations professionnelles au fil de l’histoire sociale, de l’évolution des différentes formes de regroupements, et adaptées au cours des cycles économiques. Ces relations se sont transformées afin de satisfaire différents besoins et de couvrir différents risques. L’Abbé Pierre, fondateur du Mouvement Emmaüs a créé une structure permettant la protection sociale et l’emploi des populations exclues. Cette structure s’inspire d’anciennes formes de structures solidaires, les communautés ; et d’anciennes pratiques économiques, celles des chiffonniers. Les Communautés pratiquent une politique de "flexicurité" au niveau des conditions de travail. En effet, elles emploient des salariés, des bénévoles, mais aussi un troisième acteur : le Compagnon. Celui-ci est à la fois bénéficiaire d’une aide solidaire, et travailleur dans la structure qui lui fournit cette aide. Les Communautés sont des structures productives et solidaires, soumises à des obligations de rentabilité économique et de protection sociale. La comparaison entre la France, l’Espagne et le Royaume-Uni permet de voir l’évolution des relations de travail dans ces structures, selon des contextes économiques différents. La rationalité des communautés évolue selon leurs positions au coeur des différents marchés. Plus une Communauté s’éloigne de l’idéologie solidaire du mouvement, plus elle adopte des principes marchands. Cette flexibilité détermine la trajectoire professionnelle des Compagnons et les régimes communautaires de protection solidaire, créées par Emmaüs. / The Third Sector Structures have developed a form of Industrial Relations, linked to the Social Movement History; based on the evolution of different Cooperative groups; and adapted over the business cycle. This Relation System improves the well-being of individuals and Groups, it has evolved to suit social needs and to cover various risks. Abbé Pierre, founder of the Emmaus Movement has created a Structure providing supportive environment, social benefits and work for homeless people. This structure is similar to old forms of Charity and Cooperative structure, "Communities". It deals with old economic activities, those of "Ragpickers". Emmaüs Communities practice "Flexicurity" working policies. Indeed, they have staffs, volunteers, but also a third type of worker: the Companion. The Companion is both Social beneficiary and Worker in the structure that provides him Social benefits. Communities are both supportive and productive structures, dealing with Industrial and Welfare requirements. The comparison between France, Spain and the UK shows the evolution of Industrial Relations into the Communities, within different economical contexts. The Community’ Strategy evolves according to their positions on the Market. "The far, a Community is from Emmaus Movement’s Ideology, the more it adopts market principles". This flexibility determines the Career path of Companions. It conditions the Communities Welfare and Solidarity System.

De nos jours, les robots compagnons présentent de réelles capacités et fonctionnalités. Leurs acceptabilité dans nos habitats est cependant toujours un objet d'étude du fait que les motivations et la valeur du companionage entre robot est enfant n'a pas encore été établi. Classiquement, les robots sociaux avaient des comportements génériques qui ne prenaient pas en compte les différences inter-individuelles. De plus en plus de travaux en Interaction Humain-Robot se penchent sur la personnalisation du compagnon. Personnalisation et contrôle du compagnon permettrai une meilleure compréhension de ses comportements par l'utilisateur. Proposer une palette d'expressions du compagnon jouant un rôle social permettrait à l'utilisateur de customiser leur compagnon en fonction de leur préférences.Dans ce travail, nous proposons un système de plasticité pour l'interaction humain-robot. Nous utilisons une méthode de Design Basée Scenario pour expliciter les rôles sociaux attendu des robot compagnons. Puis en nous appuyant sur la littérature de plusieurs disciplines, nous proposons de représenter ces variations de comportement d'un robot compagnon par les styles comportementaux. Les styles comportementaux sont défini en fonction du rôle social grâce à des paramètres d'expressivité non-verbaux. Ces paramètres (statiques, dynamiques et décorateurs) permettent de transformer des mouvements dit neutres en mouvements stylés. Nous avons mener une étude basée sur des vidéos, qui montraient deux robots avec des mouvement stylés, afin d'évaluer l'expressivité de deux styles parentaux par deux types de robots. Les résultats montrent que les participants étaient capable de différentier les styles en termes de dominance et d'autorité, en accord avec la théorie en psychologie sur ces styles. Nous avons constater que le style préféré par les parents n'étaient pas corréler à leur propre style en tant que parents. En conséquence, les styles comportementaux semblent être des outils pertinents pour la personnalisation social du robot compagnon par les parents.Une seconde expérience, dans un appartement impliquant 16 enfants dans des interaction enfant-robot, a montré que parents et enfants attendent plutôt d'un robot d'être polyvalent et de pouvoir jouer plusieurs rôle à la maison. Cette étude a aussi montré que les styles comportementaux ont une influence sur l'attitude corporelle des enfants pendant l'interaction avec le robot. Des dimensions classiquement utilisées en communication non-verbal nous ont permises de développer des mesures pour l'interaction enfant-robot, basées sur les données capturées avec un capteur Kinect 2.Dans cette thèse nous proposons également la modularisation d'une architecture cognitive et affective précédemment proposé résultant dans l'architecture Cognitive et Affective orientées Interaction (CAIO) pour l'interaction social humain-robot. Cette architecture a été implémenter en ROS, permettant son utilisation par des robots sociaux. Nous proposons aussi l'implémentation des Stimulus Evaluation Checks (SECs) de [Scherer, 2009] pour deux plateformes robotiques permettant l'expression dynamique d'émotion.Nous pensons que les styles comportementaux et l'architecture CAIO pourront s'avérer utile pour l'amélioration de l'acceptabilité et la sociabilité des robot compagnons. / Companion robots are technologically and functionally more and more efficient. Capacities and usefulness of companion robots is nowadays a reality. These robots that have now more efficient are however not accepted yet in home environments as worth of having such robot and companionship hasn't been establish. Classically, social robots were displaying generic social behaviours and not taking into account inter-individual differences. More and more work in Human-Robot Interaction goes towards personalisation of the companion. Personalisation and control of the companion could lead to better understanding of the robot's behaviour. Proposing several ways of expression for companion robots playing role would allow user to customize their companion to their social preferences.In this work, we propose a plasticity framework for Human-Robot Interaction. We used a Scenario-Based Design method to elicit social roles for companion robots. Then, based on the literature in several disciplines, we propose to depict variations of behaviour of the companion robot with behavioural styles. Behavioural styles are defined according to the social role with non-verbal expressive parameters. The expressive parameters (static, dynamic and decorators) allow to transform neutral motions into styled motion. We conducted a perceptual study through a video-based survey showing two robots displaying styles allowing us to evaluate the expressibility of two parenting behavioural styles by two kind robots. We found that, participants were indeed able to discriminate between the styles in term of dominance and authoritativeness, which is in line with the psychological theory on these styles. Most important, we found that styles preferred by parents for their children was not correlated to their own parental practice. Consequently, behavioural styles are relevant cues for social personalisation of the companion robot by parents.A second experimental study in a natural environment involving child-robot interaction with 16 children showed that parents and children were expected a versatile robot able to play several social role. This study also showed that behavioural styles had an influence on the child's bodily attitudes during the interaction. Common dimension studied in non-verbal communication allowed us to develop measures for child-robot interaction, based on data captured with a Kinect2 sensor .In this thesis, we also propose a modularisation of a previously proposed affective and cognitive architecture resulting in the new Cognitive, Affective Interaction Oriented (CAIO) architecture. This architecture has been implemented in ROS framework allowing it to use it on social robots. We also proposed instantiations of the Stimulus Evaluation Checks of [Scherer, 2009]for two robotic platforms allowing dynamic expression of emotions.Both behavioural style framework and CAIO architecture can be useful in socialise companion robots and improving their acceptability.

Dans ce travail, nous considérons le cas d'un robot mobile d'intérieur dont l'objectif est de détecter les humains présents dans l'environnement et de se positionner physiquement par rapport à eux, dans le but de mieux percevoir leur état. Pour cela, le robot dispose de différents capteurs (capteur RGB-Depth, microphones, télémètre laser). Des contributions de natures variées ont été effectuées :Classification d'événements sonores en environnement intérieur : La méthode de classification proposée repose sur une taxonomie de petite taille et est destinée à différencier les marqueurs de la présence humaine. L'utilisation de fonctions de croyance permet de prendre en compte l'incertitude de la classification, et de labelliser un son comme « inconnu ».Fusion audiovisuelle pour la détection de locuteurs successifs dans une conversation : Une méthode de détection de locuteurs est proposée dans le cas du robot immobile, placé comme témoin d'une interaction sociale. Elle repose sur une fusion audiovisuelle probabiliste. Cette méthode a été testée sur des vidéos acquises par le robot.Navigation dédiée à la détection d'humains à l'aide d'une fusion multimodale : A partir d'informations provenant des capteurs hétérogènes, le robot cherche des humains de manière autonome dans un environnement connu. Les informations sont fusionnées au sein d'une grille de perception multimodale. Cette grille permet au robot de prendre une décision quant à son prochain déplacement, à l'aide d'un automate reposant sur des niveaux de priorité des informations perçues. Ce système a été implémenté et testé sur un robot Q.bo.Modélisation crédibiliste de l'environnement pour la navigation : La construction de la grille de perception multimodale est améliorée à l'aide d'un mécanisme de fusion reposant sur la théorie des fonctions de croyance. Ceci permet au robot de maintenir une grille « évidentielle » dans le temps comprenant l'information perçue et son incertitude. Ce système a d'abord été évalué en simulation, puis sur le robot Q.bo. / In this work, we consider the case of mobile robot that aims at detecting and positioning itself with respect to humans in its environment. In order to fulfill this mission, the robot is equipped with various sensors (RGB-Depth, microphones, laser telemeter). This thesis contains contributions of various natures:Sound classification in indoor environments: A small taxonomy is proposed in a classification method destined to enable a robot to detect human presence. Uncertainty of classification is taken into account through the use of belief functions, allowing us to label a sound as "unknown".Speaker tracking thanks to audiovisual data fusion: The robot is witness to a social interaction and tracks the successive speakers with probabilistic audiovisual data fusion. The proposed method was tested on videos extracted from the robot's sensors.Navigation dedicated to human detection thanks to a multimodal fusion:} The robot autonomously navigates in a known environment to detect humans thanks to heterogeneous sensors. The data is fused to create a multimodal perception grid. This grid enables the robot to chose its destinations, depending on the priority of perceived information. This system was implemented and tested on a Q.bo robot.Credibilist modelization of the environment for navigation: The creation of the multimodal perception grid is improved by the use of credibilist fusion. This enables the robot to maintain an evidential grid in time, containing the perceived information and its uncertainty. This system was implemented in simulation first, and then on a Q.bo robot.

A agrofloresta visa diminuir os efeitos ocasionados pela interferência humana no ambiente auxiliando a conservação da biodiversidade. Neste trabalho o objetivo foi verificar os indicadores químicos, físicos e biológicos do solo de uma agrofloresta em desenvolvimento inicial. O estudo foi realizado na unidade didática/demonstrativa de agrofloresta, localizada na Universidade Tecnológica Federal do Paraná (UTFPR), Câmpus Dois Vizinhos. Foram coletadas amostras de solo e instaladas armadilhas para amostragem da fauna epiedáfica em seis áreas (tratamentos), sendo: quatro quadrantes da agrofloresta, uma área de mata secundária e uma área em sistema de integração lavoura-pecuária. As coletas foram realizadas em 2013 e em 2015, ambas no mês de novembro, em seis pontos de coleta (pseudoreptições), estratificadas em três profundidades: 0-5, 5-10 e 10-20 cm. As análises químicas de solo realizadas foram de teor de macronutrientes, alumínio e matéria orgânica e calculados índices relacionados. As análises físicas realizadas foram de densidade, macroporosidade e microporosidade. Também foi realizada avaliação da resistência do solo à penetração com uso de penetrômetro. A fauna epiedáfica foi coletada com armadilhas Pitfall-traps. Para avaliação da atividade microbiana do solo foi determinada a mineralização do C-CO2 na camada de 0-5 cm. Os dados foram submetidos à Análise de Variância, seguida de comparação de médias dos tratamentos pelo teste de Scott-Knott. Para verificar se existia diferenças entre os anos de coleta (2013 e 2015) foi aplicado o teste pareado de Wilcoxon ou o teste t pareado. Os indicadores de qualidade física do solo da agrofloresta estão em níveis intermediários, semelhantes em sua maioria ao sistema de integração lavoura pecuária, mas ainda abaixo dos indicadores de uma mata nativa secundária. Foi possível verificar que comparando as avaliações de 2013 com as de 2015, não houve diferença significativa para grande parte das variáveis analisadas. A avaliação da melhoria do solo de uma agrofloresta com pouco tempo de implantação, pode ser realizada utilizando os atributos físicos e biológicos do solo. / Agroforestry aims to reduce the effects caused by human interference in the environment, helping to conserve biodiversity. In this work the objective was to verify the chemical, physical and biological indicators of the soil of an agroforest in initial development. The study was carried out in the didactic / demonstration unit of agroforestry, located at the Universidade Tecnológica Federal do Paraná (UTFPR), Câmpus Dois Vizinhos. Soil samples were collected and traps were installed to sample the epiedaphic fauna in six areas (treatments): four agroforestry quadrants, the secondary forest area and an area under crop-livestock integration system. The collections were carried out in 2013 and 2015, both in November, at six collection points (pseudoreptions), stratified into three depths: 0-5, 5-10 and 10-20 cm. The soil chemical analyzes were of macronutrients, aluminum and organic matter, and related indexes were calculated. The physical analyzes were of density, macroporosity and microporosity. It was also evaluated soil penetration resistance using penetrometer. Epidaphic fauna was collected with Pitfall-traps traps. To evaluate the microbial activity of the soil, the C-CO2 mineralization was determined in the 0-5 cm layer. The data were submitted to Analysis of Variance, followed by comparison of means of treatments by the Scott-Knott test. To verify if there were differences between the collection years (2013 and 2015) the Wilcoxon paired test or paired t-test was applied. The indicators of soil physical quality of agroforestry are at intermediate levels, similar to the integration system for livestock farming, but still below the indicators of a secondary native forest. It was possible to verify that comparing the evaluations of 2013 with those of 2015, there was no significant difference for most of the analyzed variables. The evaluation of the improvement of the soil of an agroforest with little time of implantation, can be realized using the physical and biological attributes of the soil.
