Abstract Little is known regarding how treatment-related changes in cerebral networks relate to symptoms of anxiety and depression in patients with glioma. Fifteen patients with left perisylvian glioma underwent resting-state fMRI and neuropsychological evaluation before and 1 month after resection. Symptoms of depression and anxiety were characterized with Beck Depression Inventory-II (BDI) and Beck Anxiety Inventory (BAI) Total scores and rates of clinically significant symptom burden. Change scores and reliable change classifications were also examined. Graph theoretical analysis was applied to fMRI connectivity matrices to calculate brain network properties. Comparison of pre- and postoperative measures were performed with Wilcoxon tests. Correlations between changes in anxiety and depression symptom measures and network properties were examined. Pre- and postoperative Total scores did not significantly differ though postoperative symptom burden trended toward reduction [Change: BDI=-1.93(5.73), BAI=-5.80(8.19)] with considerable interindividual variability noted [Change: BDI range=-12 to +6; BAI range=-18 to +6]. Preoperatively, at least mild symptoms were found in 27% of patients on BDI and 60% on BAI. Postoperatively, rates were the same for BDI while BAI was 33%. Using reliable change criteria, improvement was found in 13% of patients on BDI and 33% on BAI without any significant worsening. Significant postoperative connectivity decreases were observed in betweenness centrality [Change = -5.56(12.07), p = .031] and assortativity [Change=-.062(.096), p = .027]. Strong associations were found between pre- to postoperative differences in betweenness centrality and assortativity and changes in BDI [ρ(13)=.58 and .67, p< .02] and BAI Total scores [ρ(13)=.62 and .68, p< .01]. Anxiety and depression symptoms vary considerably postoperatively, though most patients do not show significant worsening. Variability in symptom change appears related to alterations in functional connectomics, with those showing increases in certain connectomic properties exhibiting worse postoperative anxiety and depression symptoms. Surgically-induced connectomic changes may coincide with or potentially contribute to psychological symptom differences in the postoperative setting.

Depression and anxiety have been reported in patients with multiple sclerosis (MS) and in patients with clinically isolated syndrome (CIS). However, the precise mechanisms that lead to depressive and anxiety symptoms in these patients are still unclear. In this study we evaluated with the Beck Depression Inventory (BDI) and the Beck Anxiety Inventory (BAI) patients with MS and CIS and compared them to controls. We also correlated BDI and BAI scores with clinical parameters. Kruskall-Wallis followed by Dunn's Multiple Comparison Test, Chi-square and Spearman test were used. Patients with MS had higher depressive and anxiety scores than controls. The BDI and BAI scores of patients with CIS were not significantly different from controls. There was a positive correlation between BDI, BAI and EDSS. Our results corroborate the view that MS patients have higher depression and anxiety levels than control subjects. Anxiety and depressive symptoms also seem to progress according to the severity of the disease.

The study was aimed to develop Balanced Diet Index (BDI) for Indonesian adult males. The spesific purposes of this study were to assess food consumption pattern of Indonesian adult males, to develop several alternatives of BDIs and to select the most appropriate BDI for Indonesian adult males. The design of the study was cross-sectional, using the food consumption data from Basic Health Research 2010 collected using 24-hours recall method. The data covered 64 448 subjects, and 61 129 of them were analyzed in this study. There were 10 alternatives of BDIs developed based on the food group and their intake, and also their scoring systems. The gold standard used to validate the BDI is the mean adequacy ratio (MAR) measured by mean nutrient adequacy of 16 nutrients. The result showed the pearson correlation coefficient of the BDI and MAR range from 0.46 to 0.64. The most appropriate BDI to determine MAR is BDI3-60 (r=0.64). BDI3-60 consists of six food and implementing 3-level of scoring system.<br /><br />

Clinical psychologists often use the Beck Depression Inventory, 2nd edition (BDI-II), and Beck Anxiety Inventory (BAI) to aid in the diagnosis of mental health issues and verify the effectiveness of treatments. Despite this common practice, studies that implement a cross-cultural design to check psychometric properties and the invariance of these scales are still scarce in the literature, which can lead to biased results that prevent comparisons among different groups. The present study investigated the internal structure of both tools and their level of invariance. From a representative sample of undergraduate students from Spain (n = 1216), Portugal (n = 426), and Brazil (n = 315), Confirmatory Factor Analysis and Multigroup Confirmatory Factor Analysis were performed. The results revealed suitable fit indices for the two-factor structure of the BDI-II and BAI, assessed by Confirmatory Factor Analysis procedures. Additionally, the two-factor model of the BDI-II reached invariant properties at three levels, whereas the structural model of the BAI did not. Altogether, these results suggest using the BDI-II in this group in these three countries and imply that BAI scores should be interpreted cautiously.

Cancer is a devastating disease that has significant psychological and biological impacts. Generally, lung cancer primarily affects men while breast cancer primarily affects women. Thus, this study aimed to investigate the levels of anxiety and depression in patients with these prevalent cancer types, as well as their perceptions of the illness and any potential connections between them. The study included a total of 252 participants, consisting of 110 breast cancer patients, 112 lung cancer patients, and 30 healthy individuals as controls. The Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI) were administered to assess mood, while the Illness Perception Questionnaire (IPQ) was used to evaluate cancer perceptions. Results revealed that both breast cancer and lung cancer patients had significantly higher BDI and BAI scores compared to the control group. Furthermore, the BDI and BAI scores were lower in breast cancer patients compared to lung cancer patients. The IPQ causal representation–immunity score was significantly higher in lung cancer patients than in breast cancer patients (p = 0.01). Positive correlations were found between BDI scores and BAI scores, as well as between BDI scores and certain subscale scores of the IPQ related to illness representation and causal representation. Additionally, a positive correlation was observed between BAI scores and the IPQ illness representation–timeline acute/chronic subscale, while a negative correlation was found between BAI scores and the IPQ causal representation–accident or chance scores. Overall, the study findings demonstrated that breast and lung cancer patients possess negative perceptions of their disease and experience high levels of anxiety and depression. To enhance the quality of life and promote resilience in these patients, it is recommended to incorporate psychological interventions that consider anxiety, depression, and disease perception.

BackgroundFamilial Mediterranean Fever (FMF) is a systemic autoinflammatory disease requiring lifelong treatment, characterized by recurrent episodes of fever, arthritis, and serositis. Recent studies denote an association between FMF and behavioral disorders such as anxiety and depression[1]. Further investigations are needed to have a better understanding of the relationship of FMF to anxiety and depression.ObjectivesIn this study, we aimed to assess anxiety and depression among FMF patients and their relation to different variables such as gender, age, genotype, drug compliance, biologic treatment, family history of FMF, age of first colchicine dose, age of symptom onset, degree of education, and monthly income.MethodsWe surveyed 360 (225 F, 135 M) FMF patients in our outpatient clinic between June and October 2022. Our surveys included different inventories assessing anxiety and depression which were as follows: Beck’s Depression Inventory (BDI), Beck’s Anxiety Inventory (BAI), and State-Trait Anxiety Inventory (STAI). We then compared the inventory scores according to different variables.ResultsThe median age for the patients was 36.4 ± 11.0 (19-64). Median scores for STAI-Y1 (state), STAI-Y2 (trait), BAI, and BDI were 42.2 ± 12.0, 45.9 ± 10.6, 24.0 ± 13.9, and 13.1 ± 8.99 respectively.There was no significant difference between male and female patients on STAI-Y1, STAI-Y2, and BDI but females scored significantly higher on BAI (25.8 ± 13.7 vs 21.0 ± 13.9, p-value: 0.001). Drug compliant patients had significantly lower scores on STAI-Y1 (41.5 ± 11.4 vs 45.2 ± 14.0, p-value:0.04) compared to non-compliant patients but their scores did not significantly differ on STAI-Y2, BAI, and BDI. M694V homozygous patients got significantly lower scores from BAI and BDI (17.0 ± 12.1 vs 25.1 ± 13.9, p-value: <.001; 12.4 ±9.37 vs 13.2 ±8.93, p-value: <.001). Exon-2 mutation positive patients scored significantly higher on BAI (29.6 ± 13.3 vs 21.6 ± 13.5, p-value: <.001) but did not get significantly different scores from STAI-Y1, STAI-Y2, and BDI compared to Exon-2 mutation negative patients. The patients with Exon-10 mutation get significantly lower scores on BAI (17.9 ± 12.3 vs 27.3 ± 13.7, p-value: <.001) but positivity of Exon-10 mutation did not affect the STAI-Y1, STAI-Y2, and BDI scores significantly. Different groups of educational levels (uneducated, elementary school, secondary school, high school, university) got significantly different scores, low level groups getting higher scores, from STAI-Y2 (56.6 ± 6.80, 48.3 ± 11.6, 43.4 ± 11.0, 45.5 ± 8.63, 45.2 ± 11.2, p-value: 0.002) but all groups scored similarly on STAI-Y1, BAI, and BDI. Different groups of monthly income (<$340, $ 340-680, $ 680-1130, $ 1130+) had significantly different scores from STAI-Y2, BAI, and BDI [(46.7 ± 10.4, 45.8 ± 10.7, 40.8 ± 12.1, 41.3 ± 6.31, p-value: 0.022), (26.1 ± 13.6, 20.9 ± 13.7, 20.1 ± 13.9, 26.2 ± 16.7, p-value: 0.004), (14.0 ± 9.16, 12.2 ± 8.64, 9.88 ± 8.55, 12.3 ± 7.89, p-value: 0.034)] whereas they all had similar scores from STAI-Y1.Having a family member with FMF, biologic agent treatment, age of onset for symptoms, and the colchicine starting age did not have a significant impact on the scores taken from all four inventories.ConclusionOur patients had moderate anxiety according to BAI scores, and severe state and trait anxiety according to STAI-Y1, STAI-Y2 scores all of which indicates the presence of anxiety. Medication compliant patients had lower levels of anxiety. We argue that this difference was due to better disease control because of drug compliance. Furthermore, BDI scores indicated mild depression among patients. In addition, M694V homozygous patients interestingly had lower anxiety and depression levels. Further investigations are necessary to understand the effect of different variables on anxiety and depression in FMF patients.Reference[1]Lidor I, Tiosano S, Sharif K, Amital H, Cohen AD, Amital D.

Objective This study aims to investigate the levels of nesfatin-1-hormone in patients with Antisocial Personality Disorder (ASPD) and their relationship with clinical variables.Methods A total of 90 people (45 ASPD, 45 controls) were included in our study. Sociodemographic Data Form, Beck-Depression-Inventory (BDI), Beck-Anxiety-Inventory (BAI), Barratt Impulsivity Scale (BIS-11), Buss-Durkee-Hostility-Inventory (BDHI) were applied to all participants. Venous blood samples were taken from participants at the same time of the day when they were hungry.Results It was found that the BDI and BAI scores of the ASPD were higher than those of the controls (p<0.001, for both scales). The scores in BIS-11; motor and nonplanning-impulsivity subscales were higher than those of the controls (p<0.001, 0.036, respectively). The scores obtained by the ASPD were higher in all subscales of BDHI (p<0.001). For the nesfatin-1-hormone, the values of the ASPD were lower than those of the controls (p=0.044). No relationship was found between the nesfatin-1-hormone and any other laboratory parameters and applied scales (p>0.05).Conclusion This is the first study to examine the nesfatin-1-hormone levels in patients with any personality disorder. Further studies with more participants are needed in different types of personality disorders to understand the relationship between personality disorder and nesfatin-1-hormone levels.

Objective This study was performed to investigate the associations of life event stress with impulsivity, anxiety, and depressed mood as a function of the presence of a sleep disturbance.Methods In total, 214 participants (age 38.96±10.53 years; 111 females) completed self-report questionnaires, including the Life Experience Survey (LES), Pittsburgh Sleep Quality Index (PSQI), Barratt’s Impulsivity Scale (BIS), Beck Anxiety Inventory (BAI), and Beck Depression Inventory (BDI). The presence of a sleep disturbance was defined as a PSQI score >5.Results In total, 127 participants presented with a sleep disturbance (age 39.33±10.92 years; 64 females), whereas the remaining 87 did not (age 38.43±9.97 years; 47 females). Negative LES scores were significantly correlated with BIS (r=0.22, p=0.001), BAI (r=0.46, p< 0.001), and BDI (r=0.51, p<0.001) scores, and PSQI scores were significantly correlated with BAI (r=0.49, p<0.001) and BDI (r=0.60, p< 0.001) scores. Moderation analysis revealed statistically significant interactions between negative LES scores and the presence of a sleep disturbance on BIS (p=0.044) and BDI (p=0.014) but not on BAI (p=0.194) scores.Conclusion The findings of the present study suggest that life event stress has varying degrees of influence on mental health, especially impulsivity and depressed mood, depending on the presence or absence of a sleep disturbance.

The effectiveness of the Beck Anxiety (BAI-PC) and Depression (BDI-PC) Inventories for Primary Care for discriminating 56 primary care patients with and without revised, third edition Diagnostic and Statistical Manual of Mental Disorders ( DSM-III-R) diagnosed anxiety and mood disorders was studied. The Anxiety and Mood modules from the Primary Care Evaluation of Mental Disorders (PRIME-MD) were used to establish diagnoses. The coefficient alphas for the BAI-PC and BDI-PC were, respectively, .90 and .88. A BAI-PC cutoff score of 5 and above yielded the highest clinical efficiency (82%) with 85% sensitivity and 81% specificity for identifying patients with and without panic, generalized anxiety, or both disorders, whereas a BDI-PC cutoff score of 6 and above afforded the highest clinical efficiency (92%) with 83% sensitivity and 95% specificity for detecting patients with and without major depressive disorders. The use of these instruments to screen primary care patients before conducting extensive diagnostic evaluations with them was discussed.

IntroductionRecently, orthognathic surgeries have gained popularity in orthodontics settings. The perception of body image is a driving force in individuals who seek orthodontic treatments. Therefore, the clinician should be suspicious of underlying psychological conditions, namely body dysmorphic disorder (BDD). Indices like the “index of complexity, outcome, and need” (ICON) in orthodontics not only objectively determine malocclusion traits but also consider the influence of subjective beauty perspectives.ObjectivesThis study aimed to assess if dentists can use an objective orthodontics index in order to screen for and detect BDD among their patients.MethodsThis case-control study was conducted in the Faculty of Dentistry at Mashhad University of Medical Sciences, Mashhad, Iran. In total, 414 women were recruited between January 2019 and April 2020. After determining the ICON index, applicants filled out a demographic questionnaire, the Beck depression inventory (BDI II), Beck anxiety inventory (BAI), and Yale-Brown Obsessive-Compulsive Scale Modified for Body Dysmorphic Disorder (BDD-YBOCS).ResultsIn total, 31 (15%) cases in the orthodontics group and 21 (10.1%) subjects in the control group had a score of 20 or higher on the BDD-YBOCS (p=0.182). Moreover, there was no significant difference between groups in the mean BDD-YBOCS (p=0.184), BAI (p=0.163), and BDI-II (p=0.147). However, a statistically significant difference was found between the orthodontics patients and controls in the mean ICON index score (p<0.001). No correlation was found between the severity of ICON and BDD-YBOCS scores in all participants (p=0.804), cases (p=0.655), nor controls (p=0.403).ConclusionsObjective indices such as ICON were not able to screen for BDD. Furthermore, BDD has an increased prevalence in patients seeking orthodontic treatments. Orthodontists should look for BDD features in patients during the first visit by careful history taking and can benefit from utilizing the BDD-YBOCS survey as a screening tool in patients who are suspected of having BDD while referring the individuals who have higher scores to psychiatrists for further clinical evaluations.Disclosure of InterestNone Declared

O 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.

In this thesis we extend BDI logics, which are normal multimodal logics with an arbitrary set of normal modal operators, from three different perspectives. Firstly, based on some recent developments in modal logic, we examine BDI logics from a combining logic perspective and apply combination techniques like fibring/dovetailing for explaining them. The second perspective is to extend the underlying logics so as to include action constructs in an explicit way based on some recent action-related theories. The third perspective is to adopt a non-monotonic logic like defeasible logic to reason about intentions in BDI. As such, the research captured in this thesis is theoretical in nature and situated at the crossroads of various disciplines relevant to Artificial Intelligence (AI). More specifically this thesis makes the following contributions: 1. Combining BDI Logics through fibring/dovetailing: BDI systems modeling rational agents have a combined system of logics of belief, time and intention which in turn are basically combinations of well understood modal logics. The idea behind combining logics is to develop general techniques that allow to produce combinations of existing and well understood logics. To this end we adopt Gabbay's fibring/dovetailing technique to provide a general framework for the combinations of BDI logics. We show that the existing BDI framework is a dovetailed system. Further we give conditions on the fibring function to accommodate interaction axioms of the type G [superscript k,l,m,n] ([diamond][superscript k] [superscript l] [phi] [implies] [superscript m] [diamond][superscript n] [phi]) based on Catach's multimodal semantics. This is a major result when compared with other combining techniques like fusion which fails to accommodate axioms of the above type. 2. Extending the BDI framework to accommodate Composite Actions: Taking motivation from a recent work on BDI theory, we incorporate the notion of composite actions, [pi]-1; [pi]-2 (interpreted as [pi]-1 followed by [pi]-2), to the existing BDI framework. To this end we introduce two new constructs Result and Opportunity which helps in reasoning about the actual execution of such actions. We give a set of axioms that can accommodate the new constructs and analyse the set of commitment axioms as given in the original work in the background of the new framework. 3. Intention reasoning as Defeasible reasoning: We argue for a non-monotonic logic of intention in BDI as opposed to the usual normal modal logic one. Our argument is based on Bratman's policy-based intention. We show that policy-based intention has a defeasible/non-monotonic nature and hence the traditional normal modal logic approach to reason about such intentions fails. We give a formalisation of policy-based intention in the background of defeasible logic. The problem of logical omniscience which usually accompanies normal modal logics is avoided to a great extend through such an approach.

Streszczenie:
One of the limitations of the BDI (Belief-Desire-Intention) model is the lack of any explicit mechanisms within the architecture to be able to learn. In particular, BDI agents do not possess the ability to adapt based on past experience. This is important in dynamic environments as they can change, causing previously successful methods for achieving goals to become inefficient or ineffective. We present a model in which learning, analogous reasoning, data pruning and learner accuracy evaluation can be utilised by a BDI agent and verify this model experimentally using Inductive and Statistical learning. Intelligent Agents are a new way of developing software applications. They are an amalgam of Artificial Intelligence (AI) and Software Engineering concepts that are highly suited to domains that are inherently complex and dynamic. Agents are software entities that are autonomous, reactive, proactive, situated and social. They are autonomous in that they are able to make decisions on their own volition. They are situated in some environment and are reactive to this environment yet are also capable of proactive behaviour where they actively pursue goals. They are capable of social behaviour where communication can occur between agents. BDI (Belief Desire Intention) agents are one popular type of agent that support complex behaviour in dynamic environments. Agent adaptation can be viewed as the process of changing the way in which an agent achieves its goals. We distinguish between 'reactive' or short-term adaptation, 'long-term' or historical adaptation and 'very long term' or evolutionary adaptation. Short-term adaptation, an ability that current BDI agents already possess, involves reacting to changes in the environment and choosing alternative plans of action which may involve choosing new plans if the current plan fails. 'Long-term' or historical adaptation entails the use of past cases during the reasoning process which enables agents to avoid repeating past mistak es. 'Evolutionary adaptation' could involve the use of genetic programming or similar techniques to mutate plans to lead to altered behaviour. Our work aims to improve BDI agents by introducing a framework that allows BDI agents to alter their behaviour based on past experience, i.e. to learn.

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)

Streszczenie:
Um dos problemas do paradigma BDI quando se integram agentes a ambientes virtuais ou simuladores é a ausência de controle sobre as suas percepções. Não havendo alguma forma de percepção direcionada ao objetivo, o agente pode ser inundado por informações irrelevantes causando um aumento injustificado do tempo de processamento. Com o objetivo de fornecer um maior controle sobre as percepções do agente e reduzir o seu tempo de resposta, este trabalho apresenta um mecanismo de filtragem das percepções para o interpretador Jason que visa eliminar aquelas percepções que podem ser ignoradas. Para tal, foram propostos e implementados alguns tipos de filtros pré-definidos, que foram aplicados a três cenários diferentes. Através de validações estatísticas apropriadas, mostrou-se que a aplicação de filtros de percepção pode reduzir em até 80% o tempo de processamento de um agente, sem afetar significativamente o seu desempenho medido em termos de sua função de utilidade.
When 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.

Darbe nagrinėjami sekvenciniai skaičiavimai BDI logikoms. BDI logikos yra plačiai naudojamos agentinių sistemų aprašymui ir realizavimui. Agentai yra autonomiškos sistemos, kurios veikia kažkurioje aplinkoje ir siekia įvykdyti iš anksto apibrėžtus tikslus. Sprendimų priėmimo realizavimas yra svarbiausia ir sudėtingiausia dalis realizuojant agentines sistemas. Sprendimo priėmimo realizavimui gali būti naudojami logikos skaičiavimai. Šiame darbe ir yra nagrinėjami sekvenciniai skaičiavimai BDI logikoms. BDI logikose, kaip ir kitose modalumo logikose, yra naudojama ciklų paieška išsprendžiamumui gauti. Neefektyvi ciklų paieška užima didesnę išvedimų paieškos resursų dalį. Kai kurioms modalumo logikoms yra žinomi becikliai skaičiavimai ar skaičiavimai naudojantys efektyvią ciklų paiešką. Šiame darbe yra pateikiamas beciklis sekvencinis skaičiavimas KD45 logikai, kuri yra esminis BDI logikų fragmentas. Pateiktas skaičiavimas ne tik eliminuoja ciklų paiešką, bet ir supaprastina patį sekvencijos išvedimą. Skaidaus laiko logikai (kitam BDI logikų fragmentui) yra pateikiamas sekvencinis skaičiavimas naudojantis efektyvią ciklų paiešką. Gauti rezultatai yra pritaikyti sukuriant sekvencinius skaičiavimus vianaagentinei ir daugiaagentinei BDI logikoms. Pristatyti skaičiavimai naudoja tik apribotą ciklų paiešką. Be to, kai kurių tipų ciklus eliminuoja visiškai. Šie rezultatai įgalina kurti efektyvesnes agentines sistemas, paremtas BDI logikomis.
Sequent 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.

Streszczenie:
In this thesis we extend BDI logics, which are normal multimodal logics with an arbitrary set of normal modal operators, from three different perspectives. Firstly, based on some recent developments in modal logic, we examine BDI logics from a combining logic perspective and apply combination techniques like fibring/dovetailing for explaining them. The second perspective is to extend the underlying logics so as to include action constructs in an explicit way based on some recent action-related theories. The third perspective is to adopt a non-monotonic logic like defeasible logic to reason about intentions in BDI. As such, the research captured in this thesis is theoretical in nature and situated at the crossroads of various disciplines relevant to Artificial Intelligence (AI). More specifically this thesis makes the following contributions: 1. Combining BDI Logics through fibring/dovetailing: BDI systems modeling rational agents have a combined system of logics of belief, time and intention which in turn are basically combinations of well understood modal logics. The idea behind combining logics is to develop general techniques that allow to produce combinations of existing and well understood logics. To this end we adopt Gabbay's fibring/dovetailing technique to provide a general framework for the combinations of BDI logics. We show that the existing BDI framework is a dovetailed system. Further we give conditions on the fibring function to accommodate interaction axioms of the type G [superscript k,l,m,n] ([diamond][superscript k] [superscript l] [phi] [implies] [superscript m] [diamond][superscript n] [phi]) based on Catach's multimodal semantics. This is a major result when compared with other combining techniques like fusion which fails to accommodate axioms of the above type. 2. Extending the BDI framework to accommodate Composite Actions: Taking motivation from a recent work on BDI theory, we incorporate the notion of composite actions, [pi]-1; [pi]-2 (interpreted as [pi]-1 followed by [pi]-2), to the existing BDI framework. To this end we introduce two new constructs Result and Opportunity which helps in reasoning about the actual execution of such actions. We give a set of axioms that can accommodate the new constructs and analyse the set of commitment axioms as given in the original work in the background of the new framework. 3. Intention reasoning as Defeasible reasoning: We argue for a non-monotonic logic of intention in BDI as opposed to the usual normal modal logic one. Our argument is based on Bratman's policy-based intention. We show that policy-based intention has a defeasible/non-monotonic nature and hence the traditional normal modal logic approach to reason about such intentions fails. We give a formalisation of policy-based intention in the background of defeasible logic. The problem of logical omniscience which usually accompanies normal modal logics is avoided to a great extend through such an approach.

Streszczenie:
Individualmente, as linhas de pesquisa da Inteligência Artificial têm proposto abordagens para a resolução de inúmeros problemas complexos do mundo real. O paradigma orientado a agentes provê os agentes autônomos, capazes de perceber os seus ambientes, reagir de acordo com diferentes circunstâncias e estabelecer interações sociais com outros agentes de software ou humanos. As redes Bayesianas fornecem uma maneira de representar graficamente as distribuições de probabilidades condicionais e permitem a realização de raciocínios probabilísticos baseados em evidências. As ontologias são especificações explícitas e formais de conceituações, que são usadas em uma variedade de áreas de pesquisa, incluindo os Sistemas Multiagentes. Contudo, existem aplicações cujos requisitos não podem ser atendidos por uma única tecnologia. Circunstâncias como estas exigem a integração de tecnologias desenvolvidas por distintas áreas da Ciência da Computação. Esta dissertação trata a integração do modelo de agentes BDI (Belief-Desire-Intention) e das redes Bayesianas. Além disso, é adotada uma abordagem baseada em ontologias para representar o conhecimento incerto dos agentes. O primeiro passo em direção a integração foi o desenvolvimento de uma ontologia para representar a estrutura das redes Bayesinas. Esta ontologia tem como principal objetivo permitir a interoperabilidade agentes compatíveis com a arquitetura proposta. No entanto, a ontologia também facilita o entendimento necessário para abstrair os estados mentais e processos cognitivos dos agentes através de elementos das redes Bayesianas. Uma vez construída a ontologia, a mesma foi integrada com a arquitetura BDI. Através da integração do modelo BDI com as redes Bayesianas foi obtida uma arquitetura cognitiva de agentes capaz de deliberar sob incerteza. O processo de integração foi composto de duas etapas: abstração dos estados mentais através de elementos das redes Bayesianas e especificação do processo deliberativo. Finalmente, foi desenvolvido um estudo de caso, que consistiu na aplicação da arquitetura proposta no Agente Social, um componente de um portal educacional multiagente (PortEdu).
Individually, 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).

Streszczenie:
While the use of distributed intelligence has been incrementally spreading in the design of a great number of intelligent systems, the field of Artificial Intelligence in Real Time Strategy games has remained mostly a centralized environment. Despite turn-based games have attained AIs of world-class level, the fast paced nature of RTS games has proven to be a significant obstacle to the quality of its AIs. Chapter 1 introduces RTS games describing their characteristics, mechanics and elements. Chapter 2 introduces Multi-Agent Systems and the use of the Beliefs-Desires-Intentions abstraction, analysing the possibilities given by self-computing properties. In Chapter 3 the current state of AI development in RTS games is analyzed highlighting the struggles of the gaming industry to produce valuable. The focus on improving multiplayer experience has impacted gravely on the quality of the AIs thus leaving them with serious flaws that impair their ability to challenge and entertain players. Chapter 4 explores different aspects of AI development for RTS, evaluating the potential strengths and weaknesses of an agent-based approach and analysing which aspects can benefit the most against centralized AIs. Chapter 5 describes a generic agent-based framework for RTS games where every game entity becomes an agent, each of which having its own knowledge and set of goals. Different aspects of the game, like economy, exploration and warfare are also analysed, and some agent-based solutions are outlined. The possible exploitation of self-computing properties to efficiently organize the agents activity is then inspected. Chapter 6 presents the design and implementation of an AI for an existing Open Source game in beta development stage: 0 a.d., an historical RTS game on ancient warfare which features a modern graphical engine and evolved mechanics. The entities in the conceptual framework are implemented in a new agent-based platform seamlessly nested inside the existing game engine, called ABot, widely described in Chapters 7, 8 and 9. Chapter 10 and 11 include the design and realization of a new agent based language useful for defining behavioural modules for the agents in ABot, paving the way for a wider spectrum of contributors. Chapter 12 concludes the work analysing the outcome of tests meant to evaluate strategies, realism and pure performance, finally drawing conclusions and future works in Chapter 13.

Streszczenie:
Pensando nas milhoes de pessoas que sao afetadas mundialmente pelos transtornos depressivos (322 milhoes, sendo mais de 11 milhoes no Brasil e quase 450 mil na Suecia), tentamos criar um instrumento para avaliar depressao de forma mais eficaz. Em geral, os transtornos depressivos sao caracterizados por tristeza, perda de interesse/prazer, sentimentos de culpa ou baixa autoestima, disturbios no sono e apetite, sentimentos de cansaco, e baixa concentracao. Alem dos criterios diagnosticos, diversos instrumentos avaliam quadros depressivos. Utilizamos o Inventario de Depressao de Beck para validar a Escala CR100 de BorgR para o escalonamento de sintomas depressivos. As Escalas de Borg comecaram a ser desenvolvidas na decada de 60 para avaliacao do esforco percebido. A CR100 e uma escala de 0 a 100, com categorias verbais posicionadas de acordo com uma escala numerica gerando dados de razao. Esse tipo de escala tem diversas vantagens, como permitir a comparacao entre e dentre sujeitos e grupos, criacao de perfis de sintomas, analise de sintomas individualmente e a razao de intensidade entre eles. Essa tese consta de tres artigos usando a CR100. O Estudo I investigou as propriedades da CR100 comparada ao BDI. Cinquenta estudantes de Psicologia suecos responderam a um questionario online e os resultados mostraram uma alta correlacao entre as duas escalas (r = 0.754, p < 0.001), demonstrando que a Escala de BorgR avalia depressao tao bem quanto o BDI, entretanto fornece mais resultados. O perfil de sintomas gerado e muito mais detalhado do que o BDI, alem dos dados serem mais precisos e nao serem tao sensiveis as transformacoes matematicas. O Estudo II trata-se da validacao da CR100 para o portugues brasileiro e tal qual o Estudo I, da aplicacao em 50 estudantes brasileiros. Os resultados tambem apontam a alta correlacao entre as escalas (r = 0.824, p<0,001) com todas as caracteristicas se mantendo em ambas as nacionalidades A primeira analise de confiabilidade revelou um alto valor de alfa (entre 0.952 e 0.947) e R2 (entre 0.778 e 0.976), maiores que o BDI. O Estudo III teve como principal objetivo investigar propriedades psicometricas da CR100 em participantes depressivos (N=25) e - 10 - saudaveis (N=25), e encontrar pontos de corte para depressao leve, media e severa. A analise de confiabilidade da Escala revelou um indice alpha de 0.954 e por meio de uma reducao fatorial, os 32 itens foram agrupados em sete componentes. Tambem foi possivel construir um perfil de sintomas entre as duas populacoes corroborando a sensibilidade da CR100 em diferenciar populacao saudavel e com depressao em um intervalo de confianca de 95%. Um indice da razao entre pacientes e sujeitos saudaveis pode ser criado, gerando uma mini escala com oito itens, com um valor alpha de 0.80, e correlacao com a escala completa de r = 0.915 (p <0.001) e com o BDI de r = 0.820 (p<0,001). Os tres estudos revelaram resultados satisfatorios que vao ao encontro do que ja foi corroborado pelas pesquisas com as Escalas de BorgR. Demonstrou-se tambem ser possivel fazer o uso da CR100 para avaliar sintomas depressivos com mais informacoes e cujos dados sao mais precisos do que os instrumentos analisados
Thinking 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

Streszczenie:
Background: depression and anxiety are common symptoms observed in people with epilepsy and their relatives. Objective: Investigate associations between white matter (WM) changes and psychiatric symptoms in relatives of TLE patients. Methods: We analyzed brain MRI with DTI from 40 TLE relatives and applied the Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI). We extracted 6 WM tracts (fornix, cingulum, uncinate fasciculus (UF), inferior fronto-occipital fasciculus, corpus callosum, corticospinal tract) and analyzed fractional anisotropy (FA), medium diffusivity (MD), axial diffusivity (AD) and radial diffusivity (RD). We investigated correlations between scores and the DTI measures. Symptoms of depression were positive with BDI scores above 10, while symptoms of anxiety were positive with BAI scores above 11. Results: we observed a prevalence of 37.5% of depressive symptoms and 27.5% of anxious symptoms. BDI correlated with FA in the left cingulum (p=0.0003;r=-0.547); and with MD in the right cingulum (p=0.015;r=0.401) and right and left UF (p=0.023;r=0.374 and p=0.021;r=0.363). BDI correlated also with RD in the left and right cingulum (p=0.0003;r=0.583 and p=0.015;r=0.401). BAI correlated with fornix`s FA (p=0.026;r=- 0.352), and with MD in the left cingulum (p=0.01;r=0.415) and left UF (p=0.003;r=0.374) and with RD in the left cingulum (p=0.022;r=0.371) and left UF (p=0.01;r=0.440). Discussion: The regions correlated with psychiatric symptoms here overlap with those affected in patients with epilepsy, however, they differ from areas mainly affected in patients with isolated depression. We hypothesize a possible genetic substrate involved in comorbidity between epilepsy and depression, distinct from psychiatric disease in people without epilepsy.

Streszczenie:
The BDI model forms the basis of much of the research on symbolic models of agency and agent-oriented software engineering. While many variants of the basic BDI model have been proposed in the literature, there has been no systematic review of research on BDI agent architectures in over 10 years. In this paper, we survey the main approaches to each component of the BDI architecture, how these have been realised in agent programming languages, and discuss the trade-offs inherent in each approach.

Review question / Objective: P = Children and adolescents with psychiatric disorders; I = Cannabinoids as therapeutic product / medication; C = if randomised controlled trial, placebo; O = Evaluation of psychiatric symptoms (BDI for depression, symptom severity scales in case of ADHD or Autism Spectrum Disorders); S = Randomized controlled trials, controlled trials, case studies. Rationale: Cannabinoids especially THC and CBD have gained increasing scientific interest. Various studies have been published assessing the therapeutic applications of cannabinoids in psychiatry. Several systematic reviews have been published for application of cannabinoids in psychiatry for adults, however there is no recent systematic review assessing applications for child and adolescent psychiatry.

Streszczenie:
In low- and middle-income countries (LIMCs) measuring early childhood development (ECD) with standard tests in large scale surveys (i.e. evaluations of interventions) is difficult and expensive. Multi-dimensional screeners and single-domain tests ('short tests') are frequentlyused as alternatives. However, their validity in these circumstances is unknown. We examine the feasibility, reliability, and concurrent validity of three multi-dimensional screeners -the Ages and Stages Questionnaires (ASQ-3), the Denver Developmental Screening Test (Denver-II), the Battelle Developmental Inventory screener (BDI-2) -and two single-domain tests- the MacArthur-Bates Short-Forms (SFI and SFII) and the WHO Motor Milestones (WHO-Motor)-in 1,311 children 6-42 months in Bogota, Colombia. We compare scores on these short tests to those on the Bayley Scales of Infant and Toddler Development (Bayley-III), which we take as the 'gold standard'. The Bayley-III was given at a center by psychologists; whereas the short tests were administered in the home by interviewers, as in a survey setting. Concurrent validity of the multi-dimensional tests' cognitive, language, and fine motor scales with the corresponding Bayley-III scale is low below 19 months but increases with age, becoming moderate-to-high over 30 months. In contrast, gross motor scales' concurrence is high under 19 months and then decreases. Of the single-domain tests, the WHO-Motor has high validity with gross motor under 16 months, and the SFI and SFII expressive scales show moderate correlations with language under 30 months. Overall, the Denver-II seems the most feasible and valid multi-dimensional test and the ASQ-3 performs poorly under 31 months. By domain, gross motor development has the highest concurrence below 19 months, and language above. Results do not vary by household socio-economic status. Predictive validity investigation is nonetheless needed to further guide the choice of instruments for large scale studies.
