    This work presents the application of Artificial Neural Networks, in particular the ART2, for the customer clustering of a dentistry room. The input data used in the application is based on the odontological anamn esis that is a form with a questionnaire applied about the professional to identify the customer case history. The three proposed customer clustering (good, medium, bad) were created with basis on the buccal hygiene care and the similar habits among the cu stomers. The network is trained using non -supervised learning that can be fast or slow learning. Each input data line is formed by the number of interviewed customers (rows) and by the answered questions (columns). However, the first step was to transform the answers into binary cells.Eje: Sistemas inteligentesRed de Universidades con Carreras en InformĂĄtica (RedUNCI

    The target of this article is to research the elements present in the legislation according to the topic of inclusion and teacher training, based on the empirical analysis carried out in a basic education establishment in the State of GoiĂĄs, seeking to verify how the public service is carried out to those who presents specialized educational needs and how teacher training can contribute to the educational process of the researched school. The essay presents national and international legal documentation, which address the issue of inclusive education and the training of teachers that are devoted to special education. It was further analyzed, needs and challenges of teacher training in the educational process of the studied school. From the documentary, bibliographic and empirical perspective related to the theme of inclusive education and teacher training, the following inquiries were made: What is the idea of school inclusion and teacher training in the perspective of inclusive education? What do national and international legal bases apply to teacher training for students with disabilities? To what extent can teacher training contribute to the inclusion of these students? To answer these questions, an observation report and interviews with common classroom and resource room teachers were conducted. Documentary analysis of national and international legislation were used. The methodology used was a case study at a specific institution. The results indicate that the school community has not received initial and continuing training from the Secretary of Education of the State of GoiĂĄs and that it does not have an appropriate infrastructure for serving the public of Special Education and reveals a group of education professionals who are carrying out the work based on their own efforts and skills.O presente artigo tem como objetivo analisar os elementos presentes na legislação segundo o tema da inclusĂŁo e da formação de professores, a partir da anĂĄlise empĂ­rica realizada em uma instituição de educação bĂĄsica no Estado de GoiĂĄs, buscando verificar como Ă© realizado o atendimento ao pĂșblico que apresenta necessidades educacionais especializadas e como a formação de professores pode contribuir no processo educacional da escola pesquisada.

    Several anti-proteolytic dentin therapies are being exhaustively studied in an attempt to reduce dentin bond degradation and improve clinical performance and longevity of adhesive restorations. Objectives: This study assessed the effect of epigallocatechin-3-gallate (EGCG) on long-term bond strength when incorporated into adhesives. Material and Methods: Adhesive systems were formulated with EGCG concentrations of 0 wt%: (no EGCG; control); 0.5 wt% EGCG; 1.0 wt% EGCG, and 1.5 wt% EGCG. Flexural strength (FS), modulus of elasticity (ME), modulus of resilience (MR), compressive strength (CS), degree of conversion (DC), polymerization shrinkage (PS), percentage of water sorption (%WS), percentage of water solubility (%WL) and cytotoxicity properties were tested. Dentin microtensile bond strength (”TBS) was evaluated after 24 h and again after 6 months of water storage. The adhesive interface was analyzed using scanning electron microscopy (SEM). Results: No significant differences were found among the groups in terms of FS, ME, MR, CS and PS. EGCG-doped adhesives increased the DC relative to the control group. EGCG concentrations of 1.0 wt% and 0.5 wt% decreased the WS of adhesives. WL decreased in all cases in which EGCG was added to adhesives, regardless of the concentration. EGCG concentrations of 1.0 wt% and 0.5 wt% reduced cytotoxicity. EGCG concentrations of 1.0 wt% and 0.5 wt% preserved ”TBS after 6 months of storage, while 1.5 wt% EGCG significantly decreased ”TBS. SEM: the integrity of the hybrid layer was maintained in the 0.5 wt% and 1.0 wt% EGCG groups. Conclusion: EGCG concentrations of 1.0 wt% and 0.5 wt% showed better biological and mechanical performance, preserved bond strength and adhesive interface, and reduced cytotoxicity

    BACKGROUND AND OBJECTIVES: Anemia of critical illness is a multifactorial condition caused by blood loss, frequent phlebotomies and inadequate production of red blood cells (RBC). Controversy surrounds the most appropriate hemoglobin concentration trigger for transfusion of RBC. We aimed to evaluate transfusion practices in Brazilian ICUs. METHODS: A prospective study throughout a 2-week period in 19 Brazilian ICUs. Hemoglobin (Hb) level, transfusion rate, organ dysfunction assessment and 28-day mortality were evaluated. Primary indication for transfusion and pretransfusion hemoglobin level were collected for each transfusion. RESULTS: Two hundred thirty-one patients with an ICU length of stay longer than 48h were included. An Hb level lower than 10 g/dL was found in 33% on admission in the ICU. A total of 348 RBC units were transfused in 86 patients (36.5%). The mean pretransfusion hemoglobin level was 7.7 ± 1.1 g/dL. Transfused-patients had significantly higher SOFA score (7.9 ± 4.6 vs 5.6 ± 3.8, p < 0.05, respectively), days on mechanical ventilation (10.7 ± 8.2 vs 7.2 ± 6.4, p < 0.05) and days on vasoactive drugs (6.7 ± 6.4 vs 4.2 ± 4.0, p < 0.05) than non-transfused patients despite similar APACHE II scores (15.2 ± 8.1 vs 14.2 ± 8.1, NS). Transfused patients had higher mortality rate (43.5%) than non-transfused patients (36.3%) (RR 0.60-1.15, NS). Only one patient (0.28%) had febrile non-hemolytic transfusion and urticarial reactions. CONCLUSIONS: Anemia is common in critically ill patients.It seems from the present study that transfusion practices in Brazil have had a more restrictive approach with a lower limit transfusion trigger.JUSTIFICATIVA E OBJETIVOS: A anemia Ă© uma condição comum em pacientes graves. A transfusĂŁo de hemoderivados aumenta de forma significativa o risco de transmissĂŁo de agentes infecciosos e afeta o perfil imunolĂłgico. O objetivo deste estudo foi avaliar a incidĂȘncia de anemia e a prĂĄtica de transfusĂŁo de hemĂĄcias em UTI brasileiras. MÉTODO: Estudo prospectivo, multicĂȘntrico, realizado em 19 UTI em um perĂ­odo de duas semanas. A presença de anemia, as indicaçÔes e a utilização de concentrados de hemĂĄcias, foram avaliadas diariamente. As complicaçÔes que ocorreram durante a internação na UTI e apĂłs a transfusĂŁo da primeira unidade de concentrado de hemĂĄcias foram registradas. RESULTADOS: Um total de 33% apresentava anemia na admissĂŁo na UTI e esta proporção aumentou para 55% no final de sete dias de internação. Um total de 348 unidades de concentrado de hemĂĄcias foi transfundido em 86 pacientes (36,5%). A mĂ©dia de suas unidades por paciente foi 4,1 ± 3,3 U. O nĂ­vel de hemoglobina limiar para a transfusĂŁo de CH foi 7,7 ± 1,1 g/dL. Pacientes transfundidos tinham mais disfunçÔes orgĂąnicas avaliadas pelo escore SOFA (7,9 ± 4,6 versus 5,6 ± 3,8, transfundidos versus nĂŁo transfundidos, p < 0,05). As taxas de mortalidade foram 43,5% e 36,3% em pacientes transfundidos e nĂŁo transfundidos, respectivamente (RR 0,61-11,7, NS). Pacientes transfundidos tiveram nĂșmero maior de complicaçÔes (1,58 ± 0,66 versus 1,33 ± 0,49, p = 0,0001). CONCLUSÕES: A anemia Ă© comum em UTI brasileiras. O limiar transfusional de hemoglobina foi menor do que o observado em outros paises.Faculdade de Medicina de SĂŁo JosĂ© do Rio PretoUniversidade de SĂŁo PauloUFRGS Departamento de Medicina Interna HC de Porto AlegreUniversidade Paris VIUFRJ CTI dos Hospitais Cardiotrauma Ipanema e SĂŁo LucasAMIBUniversidade Estadual de LondrinaUFRGS FAMED HCPAFaculdade de Medicina de CatanduvaUNIFESP-EPMFundação Padre Albino UTI do Complexo HospitalarUniversidade Federal de SĂŁo Paulo (UNIFESP) Disciplina de Anestesiologia, Dor e Terapia Intensiva Setor de TerapiaSanta Casa de MisericĂłrdia de SĂŁo PauloHospital Unimed de LimeiraUTI do Hospital Regional de AssisAMIB Departamento de MedicinaAmerican CollegeFundação GetĂșlio VargasHospital PrĂł CardĂ­acoUNIRIOFGVHospital Santa Helena de GoiĂąniaHospital evangĂ©lico de Cachoeiro de Itapemirim Unidade coronarianaSBNHospital EvangĂ©lico Cachoeiro de Itapemirim UTI Adulto e CoronarianaUFRJUFRN Hospital Onofre Lopes UTIHospital Novo AtibaiaUNIFESP, EPMUNIFESP, Disciplina de Anestesiologia, Dor e Terapia Intensiva Setor de TerapiaSciEL

    AbstractThe objective of this paper was to evaluate the diversity of native species produced by nurseries in the State of Rio de Janeiro. The diagnostic and survey were conducted during the months of February, March and April of the year 2010, the research included all nurseries that produced seedlings of Atlantic Forest species. The fieldwork consisted of visits to the 70 surveyed nurseries, in which a list of the species produced in the nursery was requested and the seedling production manager was interviewed, filling in a questionnaire covering various topics related to seedlings production. We observed 277 forest species native from the Atlantic Forest produced in the nurseries. In average, the nurseries produce 56 different native species. The total diversity of native species produced in the State of Rio de Janeiro is low, as well as the mean diversity, since more than half of the nurseries work with a list of 50 or fewer species, what is insufficient considering the diversity of forest species that occur in the different vegetation types of the state.Keywords: Forest seedlings; forest restoration; Atlantic Forest.O objetivo deste trabalho foi avaliar a diversidade de espĂ©cies florestais nativas produzidas nos viveiros do estado do Rio de Janeiro.
