A Dialogue System for Coherent Reasoning with Inconsistent Knowledge Bases  [PDF]
Silvio do Lago Pereira, Luiz Felipe Zarco dos Santos, Lucio Nunes de Lira
Journal of Computer and Communications (JCC) , 2015, DOI: 10.4236/jcc.2015.38002
Abstract: Traditionally, the AI community assumes that a knowledge base must be consistent. Despite that, there are many applications where, due to the existence of rules with exceptions, inconsistent knowledge must be considered. One way of restoring consistency is to withdraw conflicting rules; however, this will destroy part of the knowledge. Indeed, a better alternative would be to give precedence to exceptions. This paper proposes a dialogue system for coherent reasoning with inconsistent knowledge, which resolves conflicts by using precedence relations of three kinds: explicit precedence relation, which is synthesized from precedence rules; implicit precedence relation, which is synthesized from defeasible rules; mixed precedence relation, which is synthesized by combining explicit and implicit precedence relations.

Abstract: Objective: To analyze the Patient Functionality Questionnaire (PFQ) scores of the patients treated with either Diclofenac + B vitamins (Group DB) or Diclofenac monotherapy (Group D) in order to better understand the impact of the combination of diclofenac with vitamins B1, B6, and B12 on quality of life. Research Design/Methods: We performed a post-hoc analysis of tabulated data generated during the DOLOR study (Diclofenac plus B vitamins versus diclofenac monotherapy in lumbago: the DOLOR study), using the software GraphPad Prism 5 for Windows, v5.04. The absolute number or percentage of “True”/“False” respondents for each questionnaire item at each study visit, together with the absolute number and percentage of subjects with no change, improvement, or worsening of each PFQ item at each study visit, within and between treatment groups were arranged on contingency tables and analyzed with the Chi-squared or Fisher’s Exact test. Results: At pretreatment there were no statistically significant differences between treatment groups (p > 0.05 for all items). At Visit 2 in both treatment groups, there were statistically significant improvements in individual question responses in each of the 12 items of the questionnaire (p < 0.05 for all items). At Visit 2, comparing the distribution of patients in each treatment group with “improvement”, “no change”, or “worsening”, there was a statistically significant superiority among subjects of group DB in response to items 1, 6, 8, and 10. At Visit 3, both groups had statistically significant (p < 0.001) improvements in each individual item of the PFQ in relation to pretreatment values. The distribution of subjects in each treatment group presenting with “improvement”, “no change”, or “worsening” at Visit 3 varied significantly in favor of group DB in the responses to item 4. At Visit 4, the subjects remaining in treatment in both groups showed statistically significant improvement in PFQ responses in relation to pretreatment values (p < 0.05). The distribution of subjects in each treatment group presenting with “improvement” or “no change” at Visit 4 varied significantly in favor of group D in the responses to items 5, 8, and 12. Conclusion: Improvement in overall PFQ scores was observed in both treatment groups, though the specific items of the questionnaire of the subjects in group DB at Visit 2 showed greater improvement in areas related to sleep quality, mobility, ability to wash and dry, ability to walk distances, and posture comfort. These results serve to corroborate the

This study aimed at evaluating the quality of melon Pele de Sapo “Mabel” and Yellow melon “UFERSA-05” minimally processed preserved in different packages. The fruits were harvested at Mossoró-RN and transported to Serra Talhada-PE. In the first study, melon fruit Piel de Sapo “Mabel” was selected, washed, weighed, cooled, peeled, cut into cube shape, sanitized in chlorine solution, drained, packaged in rigid polypropylene tray, sealed with polypropylene film or polypropylene rigid cap and kept for 8 days at 8. In the second study, fruits of yellow melon “UFERSA-05” and Pele de Sapo “Mabel” were minimally processed and kept in rigid polypropylene tray, sealed with polypropylene film and stored for 8 days at 8. There was no significant interaction between packaging (sealed with film and polypropylene cover) and period of conservation, for pH, total titratable acidity (TTA), total soluble solids (TSS) and Loss of fresh mass (LFM) for Melon “Mabel”. While there was significant interaction between types of melon (“UFERSA-05” and “Mabel”) and storage period (0, 2, 4, 6, and 8 days) for pH, TTA and TSS. In sensory evaluation were noticeable changes in appearance, flavor, aroma and flesh firmness, characterized by translucency, alcoholic aroma and softening in “Mabel” melon kept in tray with lid. Melon “UFERSA-05” showed lower pH, total soluble solids, total soluble sugars, PME activity, lack of translucency high flesh firmness compared to “Mabel” melon during storage. The high levels of sugars in melon “Mabel” may be related to the incidence of translucency, which was not observed in “UFERSA-05” melon, with a strong potential to minimal processing.

Amaral, Vanessa Cristiane de Santana;Nunes Junior, Guilhermino Pereira;
Brazilian Archives of Biology and Technology , 2008, DOI: 10.1590/S1516-89132008000600010
Abstract: ketoconazole and fluconazole are two broad-spectrum azole antifungals used for the treatment of superficial and systemic mycoses. embryotoxicity and teratogenicity have been reported in some studies when those drugs are administered at high doses to pregnant rats. the aim of this study was to present a comparative study of embryotoxic effects as well as the skeletal anomalies in fetuses of wistar rats which received ketoconazole and fluconazole at teratogenic doses on gestational days (gd) 6 through 15 (organogenesis period). on gestational day (gd) 21, the dams were euthanized and examined for standard parameters of reproductive outcome. fetuses were stained with alizarin red and the bones of the head, trunk, forelimb and hindlimb were examined for detection of skeletal anomalies. the frequency of skeletal anomalies in the ketoconazole-treated group was significant when compared to the fluconazole and the control group.

Abstract: the aim of this study was to validate a model of skeletal anomalies in rat fetuses by the administration of ketoconazole (80 mg/kg) to pregnant rats during organogenesis. bones of the head, trunk and anterior and posterior limbs were examined for detection of anomalies. statistical differences regarding the number of fetuses and postimplantation resorptions, and fetal and placental weight were significant. the frequency of skeletal anomalies in the head, trunk, and anterior and posterior limbs in the ketoconazole-treated group were also significant when compared to the control group. it could be concluded that the model suggested was valid for study of skeletal anomalies and abnormal bones development in rat fetuse, in spite of the loss of fetuses due to resorptions.
Entropia espectral: um novo método para adequa??o anestésica
Nunes, Rogean Rodrigues;Almeida, Murilo Pereira de;Sleigh, James Wallace;
Revista Brasileira de Anestesiologia , 2004, DOI: 10.1590/S0034-70942004000300013
Abstract: background and objectives: though universally employed, clinical signs to evaluate anesthetic adequacy are not reliable. over the past years several pieces of equipment have been devised to improve intraoperative handling of anesthetic drugs, some of them directly measuring cerebral cortical activity (hypnosis). none of them, however, has offered the possibility of directly evaluating sub-cortical activity (motor response). contents: spectral entropy measures irregularity, complexity or amount of eeg disorders and has been proposed as indicator of anesthetic depth. signal is collected from the fronto-temporal region and processed according to shannon's equation (h = - spk log pk, where pk represents the probability of a discrete k event), resulting in two types of analyses: 1) state entropy (se), which evaluates cerebral cortex electrical activity (0.8 - 32hz) and 2) response entropy (re), containing both subcortical electromyographic and cortical electroence- phalographic components and analyzes frequencies in the range 0.8 - 47hz. conclusions: frontal muscles activation may indicate inadequacy of the subcortical component (nociception). such activation appears as a gap between se and re. this, it is possible to directly evaluate both cortical (se) and subcortical (re) components providing better anesthetic adequacy.

Revista Brasileira em Promo??o da Saúde , 2009,
Abstract: Objective: To assess the epidemiological profile of women who spontaneously searched for the Support Group for Prevention of Functional Disability, located in Dendê Community Methods: A study developed in 2007, with a sample of 31 women, whose ages ranged from 60 to 83 years, mean 65.5 ± 5.15 years. We used a questionnaire containing Yes/No questions and multiple choices, and the instruments: a) Lawton scale: rating scale of Instrumental Activities of Daily Living (IADL); b) Katz scale: rating scale of Activities of Daily Living (ADL) and c) physical evaluation of muscle and joint functions, all in the initial stage of enrollment in the support group. Inference was performed by chi-square test, using the software SPSS version 15. Results: The participants had little schooling and low family income. It turned out the fact that 11 (35.5%) had hypertension, 8 (25.8%) osteoporosis, 9 (29.0%) diabetes and 22 (71.0%) were making use of medicines. All of them were classified as independent (average AIVD of 25.41 and AVD of 5.74). There was statistical significance between feeling weakness in the limbs and joint pain (p = 0.041); feel limb weakness and muscle pain (p = 0.038); feel limb weakness and sight problems (p = 0.004). Conclusion: The profile of the aged was of social independent womem, mostly presenting associated illnesses, making use of diverse medicines and with significant functional limitations.
Entropia espectral: um novo método para adequa o anestésica

Revista Brasileira de Anestesiologia , 2004,
Abstract: JUSTIFICATIVA E OBJETIVOS: O uso de sinais clínicos para avaliar a adequa o da anestesia, embora empregado universalmente, n o s o confiáveis. Vários equipamentos surgiram objetivando o melhor manuseio intra-operatório das drogas anestésicas, alguns deles mensurando diretamente a atividade cortical cerebral (hipnose). Entretanto, nenhum deles apresenta características diretas de avalia o da atividade sub-cortical (resposta motora). CONTEúDO: A entropia espectral mensura a irregularidade, complexidade ou a quantidade de desordem do eletroencefalograma e tem sido sugerida como um indicador do estado anestésico. O sinal é coletado na regi o fronto-temporal e tratado através da equa o de Shannon (H = - Sp k log p k, onde p k s o as probabilidades de um evento discreto k), resultando em dois tipos de análises: 1. Entropia de estado (SE), que consiste na avalia o da atividade elétrica cortical cerebral (0,8-32Hz) e 2. Entropia de resposta (RE), que analisa as freqüências de 0,8 - 47Hz (contêm componentes eletroencefalográficos-cortical e eletromiográficos-sub-cortical). CONCLUS ES: A ativa o da musculatura frontal pode indicar inadequa o do componente sub-cortical (nocicep o). Esta ativa o é observada como um "gap" entre SE e RE. Deste modo, é possível avaliar diretamente tanto o componente cortical (SE), como o sub-cortical (RE), possibilitando melhor adequa o dos componentes anestésicos.
