1. Oncologic Panendoscopy: Description of an Optimized Procedure Based on Our Experience
Abstract Introduction All patients with a new head and neck squamous cell carcinoma (HNSCC) undergo diagnostic panendoscopy as part of the screening for synchronous second primary tumors. It includes a pharyngolaryngoscopy (PLS), a tracheobronchoscopy and esophagoscopy, and a stomatoscopy. Rigid techniques are risky, with long learning curves. Objective We

2. Learning curve for endoscopic evaluation of vocal folds lesions with narrow band imaging
Resumo Introdução: Os métodos endoscópicos estão progredindo e se tornando comuns no diagnóstico clínico de rotina também na otorrinolaringologia. Um número relativamente grande de pesquisas demonstrou alta precisão na endoscopia com imagem de banda estreita na diferenciação de lesões benignas e malignas nas pregas vocais. Entretanto, pouco se

3. IMPACT OF A SIMULATED LAPAROSCOPIC TRAINING PROGRAM IN A THREE-YEAR GENERAL SURGERY RESIDENCY
RESUMO Racional: Residência em Cirurgia Geral pode durar entre 2-6 anos, dependendo do país. Residência mais curta deve otimizar a exposição dos residentes às cirurgias. Sabe-se que o treinamento cirúrgico simulado encurta as curvas de aprendizado, mas a informação relacionada à como isso afeta a residência em relação à exposição clínica �

4. Artificial neural networks modeling of kinetic curves of celeriac (Apium graveolens L.) in vacuum drying
Abstract The objective of this study was to predict celeriac drying curves using artificial neural networks (ANNs). The experimental data for vacuum drying kinetics of celeriac slices reported by other researcher in the previously published article was used. The air temperature, chamber pressure and time values were used as ANN inputs. To predict the moistu

5. Abdominal cavity simulator for skill progression in videolaparoscopic sutures in Brazil
Abstract Purpose: To develop and test a model of teaching by means of an abdominal cavity simulator. Methods: This study had two stages: development of a teaching model and an experimental prospective study that aimed to evaluate the residents’ competence. The participants were divided into 3 groups: first-year resident, second-year resident, and senior

6. The influence of previous robotic experience in the initial learning curve of laparoscopic radical prostatectomy
ABSTRACT Introduction: This study analyzed the impact of the experience with Robotic-Assisted Laparoscopic Prostatectomy (RALP) on the initial experience with Laparoscopic Radical Prostatectomy (LRP) by examining perioperative results and early outcomes of 110 patients. LRPs were performed by two ro-botic fellowship trained surgeons with daily practice in R

7. A characterization for the constitutive relationships of 42CrMo high strength steel by Artificial Neural Network and its application in isothermal deformation
In hot working process, the prediction of material constitutive relationship can improve the optimization design process. Recently, the artificial neural network models are considered as a powerful tool to describe the elevated temperature deformation behavior of materials. Based on the experimental data from the isothermal compressions of 42CrMo high streng

9. Efeitos pré e pós sinápticos dos inibidores da acetilcolinesterase na neurotransmissão em musculatura lisa.
Justification: The present work considers the effects of new inhibitors of acetylcholinesterase (AChE) on the reactivity and neurotransmission in rats and mice. The new anticholinesterase compounds, ITH12118 and ITH12117, have an hybrid stucture, derived from the molecule of of the anticholinesterase Tacrine and the 1,4 dihydropyridine nimodipine, a blocker

10. Evaluation of machine learning classifiers in keratoconus detection from orbscan II examinations
PURPOSE: To evaluate the performance of support vector machine, multi-layer perceptron and radial basis function neural network as auxiliary tools to identify keratoconus from Orbscan II maps. METHODS: A total of 318 maps were selected and classified into four categories: normal (n = 172), astigmatism (n = 89), keratoconus (n = 46) and photorefractive kerate

11. Electricity generation from the offshore wind energy source. / Geração de energia elétrica a partir da fonte eólica offshore.
In the last decade wind power source was the fastest-growing energy source. Technological learning curves for this sector fall down by a 15% a 20% rate each 3 years. Countries which are committed with wind power are running after the target of 12% wind into the worlds electrical production by 2020. The contribution of the offshore wind power (OWP) source is

12. Aprendizagem de máquina baseada na combinação de classificadores em bases de dados de área de saúde
Nowadays most decision problems do not have as a challenge the numeric treatment, but the transformation of data and information into knowledge, specially, when data bases are related with health. These health data bases, in general, have many attributes, few instances and many missing values, which, regarding machine learning, leads to redundant and irrelev
