Identifying Agile Requirements Engineering Patterns in Industry

Agile Software Development (ASD) is gaining in popularity in today´s business world. Industry is adopting agile methodologies both to accelerate value delivery and to enhance the ability to deal with changing requirements. However, ASD has a great impact on how Requirements Engineering (RE) is carried out in agile environments. The integration of Human-Centered Design (HCD) plays an important role due to the focus on user and stakeholder involvement. To this end, we aim to introduce agile RE patterns as main objective of this paper. On the one hand, we will describe our pattern mining process based on empirical research in literature and industry. On the other hand, we will discuss our results and provide two examples of agile RE patterns. In sum, the pattern mining process identifies 41 agile RE patterns. The accumulated knowledge will be shared by means of a web application.Ministerio de Economía y Competitividad TIN2013-46928-C3-3-RMinisterio de Economía y Competitividad TIN2016-76956-C3-2-RMinisterio de Economía y Competitividad TIN2015-71938-RED

Evaluating the effect of the temporomandibular disorder treatment over tinnitus

INTRODUCTION: The interaction between tinnitus and temporomandibular disorders is a very complex issue that has been long approached, because neither the etiologic factors nor the pathogenesis of such a two-way association has been clearly defined yet. Additionally, tinnitus is known to be more prevalent in temporomandibular dysfunction individuals in comparison with the general population, hence, suggesting the existence of this two-way association. OBJECTIVE: Evaluate the effect of the temporomandibular disorder treatment when tinnitus is noticed. METHODS: It is about a prospective cohort study, in which temporomandibular dysfunction (TMD) individuals showing a tinnitus before and after the dental TMD treatment were studied. Patients' age, sex, and tinnitus features - place of symptom and time length were examined, and an audiometric evaluation was performed. Intensity of tinnitus was evaluated by a digital analogue scale before and after the TMD treatment. RESULTS: We evaluated 15 TMD and tinnitus patients aged between 37. 7±17. 1, 86. 7% of whom were female. In 60% of the cases, tinnitus was unilateral and the average time length was 24 months. In 5 (33. 3%) patients, a neurosensorial hearing loss was seen at audiometry. When comparing the visual analogue scale scores before and after the dental treatment, a significant decrease (p<0,001) in the intensity of tinnitus was evident. In 4 (26. 6%) patients, tinnitus disappeared. CONCLUSION: A significant decrease in the recognition of tinnitus by patients submitted to a temporomandibular dysfunction treatment was evident.INTRODUÇÃO: A interação entre o zumbido e os distúrbios temporomandibulares é um tema que possui abordagem antiga e complexa, pois os fatores etiológicos, bem como a patogênese desta inter-relação ainda não são bem definidos. Ademais, sabe-se que o zumbido possui maior prevalência nos portadores de distúrbios temporomandibulares quando comparados com a população geral, o que sugere haver esta correlação. OBJETIVO: Avaliar o efeito do tratamento dos distúrbios temporomandibulares na percepção do zumbido. MÉTODO: Trata-se de um estudo de coorte, prospectivo, em que se estudaram pacientes portadores de distúrbios temporomandibulares (DTM) que apresentavam zumbido antes e após o tratamento odontológico do DTM. Os pacientes foram avaliados quanto à idade, sexo, caracterização do zumbido - local do sintoma e tempo de duração e avaliação auditiva através de audiometria. A intensidade do zumbido foi avaliada através de escala analógico-digital antes e após o tratamento dos DTM. RESULTADOS: Avaliamos 15 pacientes com DTM e zumbido, com idade média de 37,7±17,1 anos, sendo 86,7% do sexo feminino. Em 60% dos casos o zumbido era unilateral e a mediana do tempo de duração foi de 24 meses. Em 5 (33,3%) pacientes identificou-se perda auditiva neurossensorial a audiometria. Comparando-se os escores da escala analógico-visual antes e após o tratamento odontológico, verificou-se que houve redução significativa (p<0,001) da intensidade do zumbido. Em 4 (26,6%) pacientes houve desaparecimento do zumbido. CONCLUSÃO: Houve redução significativa na percepção do zumbido nos pacientes submetidos a tratamento das desordens temporomandibulares.Hospital do Servidor Público Municipal de São PauloUFSC Departamento de CirurgiaUFSC Departamento de OdontologiaHospital Regional de São José Dr. Homero de Miranda GomesUNIFESP-EPMUNIFESP, EPMSciEL

Síntese e caracterização de novas formas de carbono obtidas a partir da pirólise de precursores poliméricos incorporados em vidros porosos

Orientador: Aldo José G. ZarbinDissertação (mestrado) - Universidade Federal do ParanáResumo: Esta dissertação objetivou o desenvolvimento de um método template de síntese de novas formas de carbono, utilizando-se a pirólise, em atmosfera inerte, do poli-álcool furfurílico (PFA) pré-impregnado no interior de vidros porosos Vycor (PVG). A obtenção e subsequente pirólise do PFA livre também foi estudada para posterior comparação. O PVG é um material formado basicamente por Si02, com uma rede aleatória de poros nanométricos tridimensionais, interconectados entre si, contendo grupamentos Si-OH ácidos (pKa ~9) em sua superfície. Desta forma, os poros do PVG foram utilizados como matriz hospedeira para a obtenção de nanocompósitos PVG/PFA através da polimerização in situ do álcool furfurílico (FA). Os nanocompósitos inéditos PVG/PFA foram caracterizados através das técnicas de IV, RD-IV, UV-Vis, 13C-CP-MAS-RMN e 29Si-CP-MAS-RMN, que confirmam a formação do polímero com as mesmas características da resina de PFA formadas através da polimerização do FA em ambiente livre. Através deste conjunto de técnicas também foi possível identificar uma forte interação entre os grupamentos silanóis da superfície dos poros do PVG e o polímero formado em seu interior. Após a caracterização foi realizada a etapa de pirólise das amostras, sendo que os nanocompósitos PVG/C formados foram caracterizados pelas espectroscopias Raman, 13C-CP-MAS-RMN e 29Si-CP-MAS-RMN, que confirmam a formação de carbono desordenado no interior do PVG. Os nanocompósitos PVG/C foram posteriormente tratados com HF, para a dissolução da fração vítrea do nanocompósito e o carbono template obtido como fração insolúvel foi caracterizado pelas espectroscopias IV, Raman, DRX, 13C-CP-MAS-RMN e MEV. Todas as amostras de carbono template formadas apresentaram características diferentes entre si e também diferentes das notadas para o carbono formado pela pirólise do PFA livre. Um outro conjunto de amostras foi preparado na presença de catalisador metálico (partículas de Fe ou moléculas de ferroceno) através de diferentes metodologias. O tipo de polímero formado nos nanocompósitos PVG/Fe/PFA apresentou características similares àqueles formados nas amostras sem catalisador metálico. Entretanto, as amostras de carbono template obtidas na presença de catalisador metálico são mais cristalinas e mais homogêneas. Na amostra preparada com Fe metálico como catalisador ocorreu a formação de nanotubos de carbono em pequena quantidade, indicando um alto potencial para esta metodologia na busca de rotas alternativas de síntese destes materiais. Palavras-chave: poli-álcool furfurílico; carbono vítreo; síntese template.Abstract: This dissertation aims the development of methods for template synthesis of new forms of carbon. These template methods are based on the pyrolysis, in inert atmosphere, of polyfurfuryl alcohol (PFA) polymerized in situ within the pores of the Porous Vycor Glass (PVG). The synthesis and subsequent pyrolysis of the free PFA was also studied for comparison. PVG is a material formed basically by Si02, with a tridimensional, random and interconnected pore structure (with nanometric dimensions) with acid Si-O-H groups in its surface. This way, the PVG pores were used as host matrix for the formation of PVG/PFA nanocomposites by in situ polymerization of furfuryl alcohol (FA). The original nanocomposites PVG/PFA were characterized by IR, DR-IR, UV-Vis spectroscopy, 13C-CP-MAS-NMR and 29Si-CP-MAS-NMR. These techniques confirmed that the polymer obtained inside the pores of PVG has the same characteristics of the PFA resin obtained by the FA polymerization in free environment. By this group of techniques was also possible to identify a strong chemical interaction between the silanol groups of PVG and the PFA formed within its pores. All the obtained PVG/PFA samples were pyrolyzed and the polymer was converted into carbon, resulting in PVG/C nanocomposites, which were characterized by 13C-CP-MAS-NMR, 29Si-CP-MAS-NMR and Raman spectroscopy. These techniques confirmed the formation of a disordered carbon inside the PVG pore structure. The nanocomposites PVG/C were later treated with HF solution, and the glassy fraction of then was dissolved. The template carbon collected as the insoluble fraction was characterized by IR, DRX, 13C-CP-MAS-NMR, 29Si-CP-MASNMR, MEV and Raman spectroscopy. All carbon template samples showed different characteristics from the carbon sample obtained by the pyrolysis of the free PFA. Another set of samples was prepared in the presence of a metallic catalyst (Fe particles or ferrocene molecules) by different methodologies. The polymer formed in the PVG/Fe/PFA nanocomposites showed similar characteristics to that obtained in the samples prepared without the metallic catalyst. However, the template carbons sample obtained in the presence of metallic catalyst are more crystalline and homogeneous. In the sample prepared in the presence of metallic iron particles the formation of carbon nanotubes occurs, in lower yield. This last result showed that the template method proposed in this work has a high potential in the search of new routes for the synthesis of this important material.
