Pełny tekst źródłaO presente trabalho encontra-se dividido em dois artigos. O primeiro artigo, define infertilidade, suas causas e tratamentos atualmente disponíveis e analisa aspectos emocionais do paciente infértil em tratamento. As alterações psicológicas mais associadas nesses pacientes são a ansiedade e depressão e alguns aspectos tem sido identificados como influenciadores no surgimento desses transtornos. São abordados no artigo entre outros, o tempo de tratamento, expectativas dos pacientes em relação às probabilidades de sucesso, diferenças entre sexos na experiência da infertilidade, a existência ou não de uma rede de apoio provendo suporte social e diferenças culturais. Relações entre estes aspectos são realizadas e sugestões feitas para novas pesquisas na área. O segundo artigo apresentado relaciona o tratamento da infertilidade com duas alterações psicológicas, depressão e ansiedade, analisando a importância do suporte social para diminuição da severidade dos sintomas. Através da aplicação de três instrumentos, Inventário de Depressão de Beck (BDI), Inventário de Ansiedade de Beck (BAI) e Escala de Suporte Social, os níveis de depressão, ansiedade e suporte social foram acessados numa amostra de 148 sujeitos em tratamento para infertilidade. Correlacionando os dados dos três testes aplicados encontramos uma correlação significativa apenas entre os testes da Escala de Beck. Hipóteses para os achados são desenvolvidas no artigo empírico.

Intendding to understand how the human mind operates, some philosophers and psycologists began to study about rationality. Theories were built from those studies and nowadays that interest have been extended to many other areas such as computing engineering and computing science, but with a minimal distinction at its goal: to understand the mind operational proccess and apply it on agents modelling to become possible the implementation (of softwares or hardwares) with the agent-oriented paradigm where agents are able to deliberate their own plans of actions. In computing science, the sub-area of multiagents systems has progressed using several works concerning artificial intelligence, computational logic, distributed systems, games theory and even philosophy and psycology. This present work hopes to show how it can be get a logical formalisation extention of a rational agents architecture model called BDI (based in a philosophic Bratman s Theory) in which agents are capable to deliberate actions from its beliefs, desires and intentions. The formalisation of this model is called BDI logic and it is a modal logic (in general it is a branching time logic) with three access relations: B, D and I. And here, it will show two possible extentions that tranform BDI logic in a modal-fuzzy logic where the formulae and the access relations can be evaluated by values from the interval [0,1]
Com o intuito de entender como a mente humana funciona iniciaram-se estudos sobre cogni??o nos campos da filosofia e psicologia. Teorias surgiram desses estudos e, atualmente, esta curiosidade foi estendida a outras ?reas, tais como, ci?ncia e engenharia de computa??o, no entanto, nestas ?reas, o objetivo ? sutilmente diferente: entender o funcionamento da mente e aplic?-lo em uma modelagem artificial. Em ci?ncia da computa??o, a sub-?rea de sistemas multiagentes tem progredido bastante, utilizando trabalhos em intelig?ncia artificial, l?gica computacional, sistemas distribu?dos, teoria dos jogos e, aproveitando tamb?m teorias provenientes da pr?pria filosofia e psicologia. Desta forma, alguns pesquisadores j? v?em o paradigma de programa??o orientado a agentes como a melhor solu??o para a implementa??o dos softwares mais complexos: cujos sistemas s?o din?micos, n?o-determin?sticos e que podem ter de operar com dados faltosos sobre ambientes tamb?m din?micos e n?o-determin?sticos. Este trabalho busca a apresenta??o de uma extens?o da formaliza??o l?gica de um modelo de arquitetura de agentes cognitivos, chamado BDI (belief-desire-intention), na qual o agente ? capaz de deliberar suas a??es baseando-se em suas cren?as, desejos e inten??es. A formaliza??o de tal modelo ? conhecida pelo nome de l?gica BDI, uma l?gica modal com tr?s rela??es de modalidade. Neste trabalho, ser?o apresentados dois planos para transform?-la numa l?gica modal fuzzy onde as rela??es de acessibilidade e as f?rmulas (modais-fuzzy) poder?o ter valora??es dentro do intervalo [0,1]. Esta l?gica modal fuzzy h? de ser um sistema l?gico formal capaz de representar quantitativamente os diferentes graus de cren?as, desejos e inten??es objetivando a constru??o de racioc?nios fuzzy e a delibera??o de a??es de um agente (ou grupo de agentes), atrav?s dessas atitudes mentais (seguindo assim um modelo intensional)

Pełny tekst źródłaWhen agents are supposed to be integrated to virtual environments virtual or simulators, one of the BDI paradigms major concerns is the lack of control over the agents perceptions. Without having any form of goal directed perceptions, the agent may be flooded by irrelevant information thus causing an unjustified increase in processing time. In order to provide greater control on the agents perceptions and to reduce its time response, this work presents a filtering perception mechanism for the Jason interpreter, aimed at eliminating those perceptions that can be ignored. To this end, some types of pre-defined filters have been proposed, implemented, and applied to three different scenarios. Through appropriate statistical validation methods, it was shown that applying perception filters can reduce up to 80 % of an agents processing time, without significantly affecting its performance measured in terms of its utility function.

Pełny tekst źródłaSequent calculi for BDI logics is a research object of the thesis. BDI logics are widely used for agent system description and implementation. Agents are autonomous systems, those acts in some environment and aspire to achieve preassigned goals. Implementation of the decision making is the main and the most complicated part in agent systems implementation. Logic calculi may be used for the decision making implementation. In this thesis, there are researched sequent calculi for BDI logics. Sequent calculi for BDI logics, like sequent calculi for other modal logics, use loop-check technique to get decidability. Inefficient loop-check takes a major part of the resources used for the derivation. For some modal logics, there are known loop-check free sequent calculi or calculi with an efficient loop-check. In this thesis, there is presented loop-check free sequent calculus for KD45 logic, which is the main fragment of the BDI logics. Introduced calculus not only eliminates loop-check, but also simplifies sequent derivation. For the branching time logic (another BDI logic fragment) there is presented sequent calculus with an efficient loop-check. Obtained results are adapted for creation sequent calculi for monoagent and multiagent BDI logics. Introduced calculi use only restricted loop-check. Moreover, loop-check is totally eliminated for some types of the loops. These results enables to create more efficient agent systems, those are based on the BDI logics.

Pełny tekst źródłaIndividually, Artificial Intelligence research areas have proposed approaches to solve several complex real-world problems. The agent-based paradigm provided autonomous agents, capable of perceiving their environment, reacting in accordance with different situations, and establishing social interactions with other software agents and humans. Bayesian networks provided a way to represent graphically the conditional probability distributions and an evidence-based probabilistic reasoning. Ontologies are an effort to develop formal and explicit specifications of concepts, which have been used by a wide range of research areas, including Multiagent Systems. However, there are applications whose requirements can not be addressed by a single technology. Circumstances like these demand the integration of technologies developed by distinct areas of Computer Science. This work is particularly concerned with the integration of Belief-Desire-Intention (BDI) agent architecture and Bayesian networks. Moreover, it is adopted an ontology-based approach to represent the agent’s uncertain knowledge. To bring together those technologies, it was developed an ontology to represent the structure of Bayesian networks knowledge representation. This ontology supports the interoperability among agents that comply with the proposed architecture, and it also facilitates the understanding necessary to abstract the agents’ mental states and cognitive processes through elements of Bayesian networks. Once specified the ontology, it was integrated with the BDI agent architecture. By integrating BDI architecture and Bayesian networks, it was obtained a cognitive agent architecture capable of reasoning under uncertainty. It was performed in two stages: abstraction of mental states through Bayesian networks and specification of the deliberative process. Finally, it was developed a case study, which consists in applying the probabilistic BDI architecture in the Social Agent, a component of a multiagent educational portal (PortEdu).

Pełny tekst źródłaThinking about the millions of people who are affected worldwide by depressive disorders (322 million, more than 11 million in Brazil and almost 450.000 in Sweden), we tried to create an instrument to assess depression more effectively. In general, depressive disorders are characterized by sadness, loss of interest/pleasure, feelings of guilt or low self-esteem, changes in sleep and appetite, tiredness, and low concentration. In addition to the diagnostic criteria, several instruments evaluate depressive disorders. We used the Beck Depression Inventory to validate the Borg CR100 ScaleR for scaling depressive symptoms. The Borg ScalesR were developed in the 60\'s for the evaluation of perceived exertion. The CR100 is a scale from 0 to 100, with verbal categories placed in agreement with the numerical scale so as to obtain ratio data. This type of scale has several advantages, such as allowing comparison between and within subjects and groups, creating symptoms profile, analyzing individual symptoms and the intensity ratio between them. This thesis consists of three papers using the CR100. Study #1 investigated the properties of CR100 compared to BDI. Fifty Swedish students of Psychology answered an online questionnaire and the results pointed a high correlation between the two scales (r = 0.754, p <0.001), demonstrating that the Borg Scale evaluates depression as well as the BDI, providing more results though. The symptom profile generated was much more detailed than the BDI, in addition, the data was more accurate and not that sensitive to mathematical transformations. Study #2 looked after the validation of CR100 for Brazilian Portuguese and, like #1, the application in 50 Brazilian students. The results also pointed to the high correlation between the scales (r = 0.824, p <0.001) with all characteristics preserved in both nationalities. The first reliability analysis revealed a high alpha value (between 0.952 and 0.947) and R2 (between 0.778 and 0.976), higher than the BDI. The aim of Study #3 was to investigate the psychometric properties of CR100 in depressive (N = 25) and healthy participants (N = 25), and to find cutoff points for light, medium and severe depression. The reliability analysis of the Scale revealed an alpha of 0.954 and by running a factorial reduction, - 12 - the 32 items were grouped into seven components. It was also possible to construct a profile of symptoms between the two populations verifying the sensitivity of CR100 to differentiate healthy from depressive population, in a 95% confidence interval. An index of the ratio between patients and healthy subjects could be created, generating a mini scale with eight items with an alpha value of 0.80 and correlation with the full scale of r = 0.915 (p <0.001) and with the BDI of r = 0.820 (p <0.001). The three studies have shown satisfactory results that match with what has already been demonstrated by researches with the Borg ScalesR. It has also been presented the possibility of using the CR100 to assess depressive symptoms with more information and which data are more accurate than the instruments analyzed

Cyber-physical systems refer to a new generation of synergy systems with integrated computational and physical processes which interact with one other. The development and simulation of cyber-physical systems (CPSs) are obstructed by the complexity of the subsystems of which they are comprised, fundamental differences in the operation of cyber and physical elements, significant correlative dependencies among the elements, and operation in dynamic and open environments. The Multiple Belief-Desire-Intention (BDI) agent system (BDI multi-agent system) is a promising choice for overcoming these challenges, since it offers a natural way to decompose complex systems or large scale problems into decentralized, autonomous, interacting, more or less intelligent entities. In particular, BDI agents have the ability to interact with, and expand the capabilities of, the physical world through computation, communication, and control. A BDI agent has its philosophical grounds on intentionality and practical reasoning, and it is natural to combine a philosophical model of human practical reasoning with the physical operation and any cyber infrastructure. In this thesis, we introduce the BDI Model, discuss implementations of BDI agents from an ideal theoretical perspective as well as from a more practical perspective, and show how they can be used to bridge the cyber infrastructure and the physical operation using the framework. We then strengthen the framework's performance using the state-of-the-art parallel computing architecture and eventually propose a BDI agent based software framework to enable the efficient modeling and simulation of heterogeneous CPS systems in an integrated manner.

Pełny tekst źródłaThe reasoning performed in BDI agents essentially involves manipulating three data structures representing their beliefs, desires and intentions. Traditional BDI agents’ beliefs do not represent uncertainty, and may be expressed as a closed set of ground literals. The constraints that indicate whether a given desire is viable and passive to be adopted as an intention in traditional BDI agents may be represented as logical expressions over beliefs. Given that Bayesian Networks allow one to represent uncertain information probabilistically, Bayesian BDI agents employ Bayesian Networks to support uncertainty in their beliefs. In Bayesian BDI agents, beliefs represented in Bayesian Networks refer to states of event variables, holding individual dynamic probabilities that account for the uncertainty. The processes that constitute reasoning in this agent model require changes in order to accomodate this difference. Among these processes, this work is specifically concerned with desire selection. A previous strategy for desire selection is based on applying a threshold on belief probabilities. However, such an approach precludes an agent from selecting desires conditioned on beliefs with probabilities below a certain threshold, even if those desires could be achieved if they were selected. To address this limitation, we develop three alternative approaches to desire selection under uncertainty: Probability Ranking, Biased Lottery and Multi-Desire Biased Random Selection. Probability Ranking selects a desire using a list of desires sorted in decreasing order of precondition probability. Biased Lottery selects a desire using one random numeric value and desire-associated numeric intervals proportional to the probabilities of the desires’ preconditions. Multi-Desire Biased Random Selection selects multiple desires using random numeric values and considering the probabilities of their preconditions. We present examples, including theWatchman agent, as well as experiments involving the latter, to show how these approaches allow an agent to sometimes select desires whose belief preconditions have very low probabilities.

A crescente necessidade de informação e consequente aumento no volume de comunicação tem conduzido a adoção de dados semânticos e resultando numa demanda por ferramentas que manipulam tais dados. Com o avanço de dados semânticos na Web, estamos atingindo um ponto onde ferramentas de software devem se adaptar a este novo formato. Este trabalho propõe um novo modelo para desenvolvimento de agentes inteligentes da IA baseados em um modelo de logica BDI, com o objetivo de permitir comunicação livre de ambiguidade e capaz de reutilizar dados semânticos já existentes na Web. O modelo propõe uma alternativa para a representação de dados semânticos no agente, como estes dados podem ser armazenados e utilizados para comunicação com triplestores da Web Semântica e também com outros agentes (semânticos e não semânticos). Com foco na representação destes dados semânticos, são exploradas maneiras de se integrar informação semântica a um agente, seus processos e estados e porque esta integração pode levar a melhores resultados quando acessando informação na Web. Além disso, e demonstrado o ganho que se pode obter ao reutilizar dados já existentes na Web Semântica, e como isto pode facilitar o desenvolvimento de novas aplicações baseadas em agentes. Finalmente, para avaliar o modelo proposto, e feita uma comparação qualitativa com outros trabalhos na área, levantando as diferenças, motivações e melhorias feitas neste trabalho. Uma implementação deste modelo e apresentada através de um arcabouço criado para demonstrar e validar as intenções deste trabalho. Este arcabouço chamado PySA e descrito expondo os principais pontos defendidos na proposta, testando em situações hipotéticas e exemplos reais a comunicação e aprendizado semanticamente rico que são os objetivos do trabalho.
Abstract: Increasing needs for information and consequent increase in communication volume are leading to a widespread adoption of semantic data and demand for tools that manipulate such data. With the uprising of Semantic Web data, we are reaching a point where software tools must adapt to this new format. This work proposes a new model for developing intelligent agents based on a BDI reasoning model, with the goal of allowing ambiguity free communication and capable of reusing semantic data that already exists in the Web. The model proposes an alternative to representing semantic data in agents, and how this data can be stored and utilized to communicate with Semantic Web stores and also other agents (semantic and non-semantic). Focusing on the representation of this semantic data, this work explores ways to integrate semantic information to an agent, it's processes and states and why this integration can lead to better results when acessing information in the Web. On top of that, this work demonstrates what gain can be obtained from reutilizing data that already exists in the Semantic Web, and how this eases the development of new agent-based applications.Finally, to evaluate the proposed model, a qualitative comparison is made with similar work in the area, comparing the dierences, motivations and improvements made in this project. An implementation of this model is presented through a framework created to demonstrate and validate in practice the intentions of this project. This framework called PySA is described, exposing the main values defended in the proposal, testing in hypothetical situations and real examples the semantically rich communication and learning capabilities that are the main goal of this work.

Pełny tekst źródłaTo meet the needs of human populations, agriculture is increasingly intensive, using a very large number of nitrogen fertilizers to increase yields. These fertilizers are used because nitrogen is one of the most important and limiting factors for plant growth. Nitrogen in the form of nitrate is subject to pollution problems that can affect the environment and human health. The challenges for tomorrow's agriculture are therefore to face an ever-increasing population, while limiting the impact on our environment. This is why research and agriculture are increasingly questioning the use of other products such as biostimulants or inhibitors, in order to limit inputs while maintaining a viable productivity rate. One solution would be to act on soil microorganisms linked to the nitrogen cycle in order to limit nitrogen losses from agrosystems through greenhouse gas (N2O) emissions, leaching and/or volatilization. Indeed, in soils, nitrate is also used by so-called denitrifying bacteria, which reduce it to N2O (greenhouse gases) and N2, representing a loss of nitrogen for crops and an increase in air pollution. As a result, plants compete directly with these bacteria for the assimilation of nitrate. Recently, the supervising team of this thesis has highlighted a strategy developed by some plants consisting of the production of secondary metabolites: procyanidins, which inhibit the denitrification of soil microbial communities. Procyanidins have the ability to inhibit the first step of denitrification in denitrifying bacteria, transforming nitrate into nitrite and thus preventing the use of nitrate, without however exerting an antibacterial effect. This strategy therefore preserves the nitrate in the soil, which can then be used by plants for their nutrition and growth. The main objective of this thesis was to evaluate the effect of the application of exogenous procyanidins at several field concentrations on a plant model of economic interest, lettuce, as well as on different soil types. These effects have also been tested on another model of economic interest that consumes nitrogen, celery. During these experiments, measurements were made on (i) microbial denitrification activity, (ii) plant traits related to growth and (iii) the abundance of denitrifying bacterial communities. Our results show an induction of a BDI in the field, a conservation of nitrate inducing in turn an improvement in plant growth and a counter-selection by the plant of denitrifiers. The other point addressed, which was rather fundamental but less successful due to a lack of time, was to highlight, via the use of Arabidopsis thaliana mutants affected in the production of procyanidins or overproducing procyanidins, a return to the plant of nitrogen diverted following the BDI

Also, the presence of depressive symptoms could modify the adherence to the treatment and a high probability of a bad glycemic control in patients with Diabetes Mellitus type 2 (DM2). Methods: A cross-sectional analytical study was done, with 98 patients who were diagnosed with DM2, who went to the Endocrinology Department during the period of October-November 2014 in a social security hospital. We used three scales, the first one was The Beck Depression Inventory II which evaluated the presence of depressive symptoms; the scale of Problem Areas in Diabetes (PAID) evaluates the emotional stress they faced during the illness, and the Morisky-Green Scale is the third scale used which valued the adherence to the pharmacological treatment. Results: in population, the predominance was on female sex (53,8%), with a mean age of 56 years tended to be younger than 60 years (p> 0.05), married and a superior grade. BMI was associated with the presence of depressive symptoms (p 0.003), and most often found in those with obesity, type II and III. The population had 57.7% of poor glycemic control, of which 73.3% had depressive symptoms (p <0.05), and 84.1% had no adherence to treatment (p <0.05). It was found a significant association between bad glycemic control and presence of depressive symptoms independently of the potentially confounding variables with a prevalence ratio to 1.9 (1, 1 -3, 6). Conclusions: It is concluded the association between the bad glycemic control and the presence of depressive symptoms in diabetic patients. Therefore, it is suggested to use an integral approach on such patients who will be subject to a psychological evaluation.

Pełny tekst źródłaAchieving faithful representation of knowledge is a historic and still unreached goal in the area of Artificial Intelligence. Problems are solved and decisions are made taking into consideration different kinds of knowledge, from which many are biased, inaccurate, ambiguous or still incomplete. Computational systems that store knowledge in many different ways have been built in order to emulate the capacity of human knowledge representation, taking into consideration the several inherent difficulties to it. Within this context, this paper proposes an experiment that utilizes two distinct ways of representing knowledge: symbolic, BDI in this case, and probabilistic, Bayesian Networks in this case. In order to develop a proof of concept of this propose of knowledge representation, examples that will be built through agent oriented programming technology will be used. For that, implementation of a MultiAgent System was developed, extending the Jason framework through the implementation of a plugin called COPA. For the representation of probabilistic knowledge, a Bayesian Network building tool, also adapted to this system, was used. The case studies showed improvement in the management of uncertain knowledge in relation to the building approaches of classic BDI agents, i.e., that do not use probabilistic knowledge.

Pełny tekst źródłaThe goal of this thesis is to study the issue of rational BDI learning agents, situated in a multi-agent system. A rational agent can be defined as a cognitive entity endowed with intentional attitudes, e. G. , beliefs, desires, and intentions (BDI). First, we study the concepts of agency and practical reasoning, allowing agents to induce from their intentional attitudes, a behavior identified as rational. These concepts are formalized using a multi-modal BDI logic, enabling us to specify and develop a BDI architecture implemented in Lisp. The architecture is fully operational, it allows the execution of multiple BDI agents in a multi-agent system and it improves the epistemic reasoning of each agent introducing first-order theorem proving competences. Then, we study the problem of learning in the agency context and we propose a hierarchy of learning situations based on the awareness of agents about the presence of other agents in the multi-agent system. We use the first-order induction of logical decision trees to enable our BDI agents to learn the "reasons" they have to form an intention. These reasons correspond in the architecture to the trigger conditions of the plans of the agent. This learning method is included in the architecture proposed, allowing BDI agents to learn from their own experience, as if they were isolated (first level of the hierarchy proposed), and communicating with other agents in the Multi-agent System, to profit in this way of the experience of others

Em sistemas multiagentes abertos dotados de sistemas normativos é necessário que os agentes sejam capazes de deliberar sobre as normas do sistema e seus desejos pessoais. Considerando que os agentes normativos têm recursos limitados, é necessário raciocinar também sobre os recursos disponÃveis e se eles são suficientes para alcançar o objetivo implicado por uma norma. Nesta direção, o objetivo principal da tese é desenvolver uma arquitetura e um processo de raciocÃnio que juntos são capazes de deliberar sobre normas e desejos, levando em consideração os recursos finitos.

Pełny tekst źródłaAgent technology arises as a solution that provides flexibility and robustness to deal with dynamic and complex domains. Such flexibility can be achieved by the adoption of existing agent-based approaches, such as the BDI architecture, which provides agents with the mental attitudes of beliefs, desires and intentions. This architecture is highly customisable, leaving gaps to be fulfilled in particular applications. One of these gaps is the plan selection algorithm that is responsible for selecting a plan to be executed by an agent to achieve a goal, having an important influence on the overall agent performance. Most existing approaches require considerable effort for customisation and adjustment to be used in particular applications. In this dissertation, we propose a plan selection approach that is able to learn plans that provide possibly best outcomes, based on current context and agent’s preferences. Our approach is composed of a meta-model, which must be instantiated to specify plan metadata, and a technique that uses such metadata to learn and predict plan outcomes. We evaluated our approach experimentally, and results indicate it is effective. Additionally, we provide a tool to support the development process of software agents based on our work. This tool allows developers to model and generate source code for BDI agents with learning capabilities. A user study was performed to assess the improvements of a tool-supported BDI-agent-based development method, and evidences suggest that our tool can help developers that are not experts or are unfamiliar with the agent technology.

Pełny tekst źródłaVirtual humans are computational models of people. If necessary, they can portray a very realistic appearance, based on biomechanical and physiological principles. Besides, they are able to behave in an autonomous and intelligent way in dynamic environments, and even to exhibit individuality and personality. Virtual humans can be used as synthetic actors. Such kind of actors have been used in several applications, such as games, in order to simulate the presence of real actors. The computer-game industry requires characters that are able to react appropriately to unexpected events and circumstances, and even to change the game progress with their autonomous courses of actions. A natural way for developing such characters is by the use of artificial intelligence techniques, in particular those related to the areas of autonomous agents and multi-agent systems. In this work, the use of the Belief-Desire-Intention (BDI) model for cognitive agents in order to implement animated characters is proposed. The BDI model is a well-known and successful approach for the development of autonomous agents in multiagent systems. It is a very powerful architecture for dynamic and complex systems where agents may need to act under incomplete and incorrect information on other agents and their environment. This work brings together an articulated model for character animation, which requires the specification of motion on each joint individually, and an interpreter for AgentSpeak(L), an agent-oriented programming language that implements the BDI architecture. I have developed an interface that allows the BDI-based agent reasoning system to be used for guiding the behaviour of a character in an animation system. The use of AgentSpeak(L) is a promising approach for the high-level specification of complex computer animations. The conceptual model and its implementation are presented in distinct chapters. This separation aims at simplifying the comprehension of the proposed model, allowing its analysis first at a higher abstraction level, and after that to check programming details. This work also presents two 3-D animations used to illustrate the proposed approach. The main animation presented involves an agent that is situated in a dynamic environment; the agent continuously perceives the environment and reasons on how to act upon it based on its BDI mental state. The other application is quite simple, but useful to show some issues that are relevant for obtaining better performance from AgentSpeak(L) programs.

Pełny tekst źródłaRecently, many real-world applications where different entities interact in a dynamic environment, consider the use of agents in their architectures due principally to their autonomy, reactivity and decision-making abilities. Though these systems can be made intelligent, using Artificial Intelligence (AI) techniques, agents still lack of social abilities and have limited knowledge of their environment and in particular when it comes to a dynamic environment. In fact, when operating in the real world, agents need to deal with unexpected events considering both changes in time and space. Moreover, agents must face the uncertainty, which pervades real-world scenarios in order to provide an accurate representation of the world. In this thesis, we introduce and evaluate a formal framework for recommending plans to agents in the decision making process, when they deal with uncertain spatio-temporal information. The agent-based architecture we propose to address this issue, called CARS (Cognitive Agent-based Recommender System), has been designed by extending the well-known Belief-Desire-Intention (BDI) architecture to incorporate further capabilities to support reasoning with different types of contextual information, including the social context. Uncertainty on the agent's beliefs, desires and intentions is modeled using possibility theory. To meet the requirements of real-world applications, e.g., traffic and navigation recommendation systems, we define a spatio-temporal representation of the agents' beliefs and intentions. Using such a formal framework, anticipatory reasoning about intentional dynamics can be performed with the aim to recommend an optimal plan to a certain user. Since spatio-temporal data is often considered as incomplete and/or vague, we extended the formal framework with a fuzzy representation of spatio-temporal beliefs and intentions. The framework is evaluated through an Agent Based Simulation (ABS) in a real-world traffic scenario. This ABS allowed us to create a virtual environment to test the impact of the different features of our framework as well as to evaluating the main strengths and weaknesses of the proposed agent architecture

Pełny tekst źródłaThe rapid growth of urban areas has a significant impact on traffic and transportation systems. New management policies and planning strategies are clearly necessary to cope with the more than ever limited capacity of existing road networks. The concept of Intelligent Transportation System (ITS) arises in this scenario; rather than attempting to increase road capacity by means of physical modifications to the infrastructure, the premise of ITS relies on the use of advanced communication and computer technologies to handle today’s traffic and transportation facilities. Influencing users’ behaviour patterns is a challenge that has stimulated much research in the ITS field, where human factors start gaining great importance to modelling, simulating, and assessing such an innovative approach. This work is aimed at using Multi-agent Systems (MAS) to represent the traffic and transportation systems in the light of the new performance measures brought about by ITS technologies. Agent features have good potentialities to represent those components of a system that are geographically and functionally distributed, such as most components in traffic and transportation. A BDI (beliefs, desires, and intentions) architecture is presented as an alternative to traditional models used to represent the driver behaviour within microscopic simulation allowing for an explicit representation of users’ mental states. Basic concepts of ITS and MAS are presented, as well as some application examples related to the subject. This has motivated the extension of an existing microscopic simulation framework to incorporate MAS features to enhance the representation of drivers. This way demand is generated from a population of agents as the result of their decisions on route and departure time, on a daily basis. The extended simulation model that now supports the interaction of BDI driver agents was effectively implemented, and different experiments were performed to test this approach in commuter scenarios. MAS provides a process-driven approach that fosters the easy construction of modular, robust, and scalable models, characteristics that lack in former result-driven approaches. Its abstraction premises allow for a closer association between the model and its practical implementation. Uncertainty and variability are addressed in a straightforward manner, as an easier representation of humanlike behaviours within the driver structure is provided by cognitive architectures, such as the BDI approach used in this work. This way MAS extends microscopic simulation of traffic to better address the complexity inherent in ITS technologies.

Resumo: O objetivo deste estudo foi comparar a prevalência de depressão entre mulheres portadoras de endometriose com e sem queixa de dor pélvica crônica através do Inventário de Depressão de Beck. Para tal, foram entrevistadas 100 mulheres com diagnóstico cirúrgico de endometriose, divididas igualmente em dois grupos: com e sem dor. A depressão foi avaliada e classificada através do Inventário de Depressão Beck, sendo utilizado para análise estatística das variáveis o teste qui-quadrado, a Análise de Regressão Múltipla e a Análise Discriminante Multivariada. A prevalência de depressão encontrada foi: 86% no grupo com dor e 38% no grupo sem dor. A única variável significativamente associada à depressão foi a dor pélvica crônica. Queixas depressivas referentes à preocupação somática, inibição para o trabalho, falta de satisfação e tristeza/humor deprimido estiveram significativamente associadas ao grupo com dor. A queixa de sensação de fracasso foi à única associada ao grupo sem dor. Apesar da prevalência de depressão ter sido maior no grupo com dor, esse sofrimento emocional não deve ser ignorado em mulheres sem o sintoma doloroso. A avaliação e acompanhamento psicológico podem auxiliar no tratamento da endometriose, objetivando melhorar a qualidade de vida dessas mulheres
Abstract: The objective of this study was to compare the prevalence of depression between women with surgical diagnosis of endometriosis with and without pelvic pain. A total of 100 women, 50 in each group were interviewed and answered the Beck Depression Inventory. Statistical analyses were performed using the Chi-square test, Multiple Regression and Discriminated Multivariate analysis. Depression was found in 86% and 38% of the women with and without pain respectively. Depression complaints as somatic concerns, unwillingness to work, lack of satisfaction and sadness were significantly more observed in the pain group. Sensation of failure was the only variable more observed in the group without pain. Although depression was higher in the pain group, its occurrence was still high in the group without pain. The evaluation and treatment of depression can be helpful for women with endometriosis, especially those with pelvic pain

Pełny tekst źródłaA neoplasia mamária é uma doença ameaçadora e temida entre as mulheres, pois representa uma das principais causas de morte na população feminina. Além disso, tem como principal recurso terapêutico a mastectomia, que traz consequências dolorosas na vida das mulheres em virtude dos efeitos psicológicos, das limitações e das mudanças no estilo de vida. Diante do exposto, este estudo tem como objetivo: avaliar a depressão em pacientes mastectomizadas de Teresina-PI, utilizando o Inventário de Depressão de Beck (BDI). Trata-se de uma pesquisa qualitativa e quantitativa, a qual partiu de um levantamento bibliográfico em acervos bibliotecários e de publicações eletrônicas, além da utilização de alguns instrumentos de coleta de dados, como entrevista semi-estruturada e o BDI. Os dados foram analisados e organizados em quadro categorias: saberes sobre a doença; o diagnóstico de câncer; repercussões da cirurgia de mastectomia; importância do apoio familiar e do companheiro e crenças. Os resultados permitiram identificar que a mastectomia gera implicações de ordem emocional, física e social. No que se refere às implicações de ordem emocional essas mulheres apresentavam sentimentos como: medo, ansiedade, diminuição da auto-estima e depressão. No campo social, elas têm receio em relação ao preconceito da mutilação que a mastectomia prova nelas e na sociedade. Apesar de todas as implicações representadas identificou-se com aplicação do BDI que essas mulheres apresentavam quadros leves de depressão e a maioria não apresentavam. Conclui-se, portanto, que a neoplasia mamaria e a mastectomia são responsáveis por um grande impacto na vida dessas mulheres e que o apoio da família, dos amigos e do companheiro, juntamente com a fé em Deus, as ajuda a superar as dificuldades.

It introduces our logical framework, exposes and argues the formal definitions of twenty emotions, and proves some of their properties. Finally the last part is dedicated to practical applications and continuation prospects of this work. Such a work offers interesting contributions: it offers to the agent community a formal model of a great number of emotions; it shows the interest of BDI logics; and it opens research prospects about the dynamics of emotions and their influence on the behaviour of agents, a field not much explored for now
