O uso de chatbot aplicado ? t?cnica de leitura protocolada

Chatbot ? uma ferramenta computacional que possui a capacidade de simular um di?logo com uma pessoa em linguagem natural. Essa capacidade o torna ideal para a aplica??o da t?cnica de leitura protocolada, que consiste na realiza??o de perguntas sobre um texto para avaliar a compreens?o do que foi lido e estimular o leitor a produzir infer?ncias e a fazer previs?es sobre o que poder? vir em seguida. Essa pr?tica ? uma atividade cognitiva, que estimula o indiv?duo a se tornar mais qualificado a construir de forma aut?noma, independente e cont?nua o seu pr?prio conhecimento. Como essa t?cnica ? conduzida de forma presencial por um professor, o objetivo geral desta pesquisa ? aplicar a t?cnica de leitura protocolada em um texto atrav?s de um chatbot. Pretende-se investigar a possibilidade de uso dessa ferramenta na pr?tica da leitura protocolada, identificando as principais vantagens e desvantagens e de que forma poder? contribuir para o processo de constru??o do conhecimento do texto. O chatbot proposto neste trabalho, intitulado Professora Vit?ria, foi programado para aplicar a t?cnica de Leitura Protocolada no texto ?A Armadilha?, de Murilo Rubi?o. Professora Vit?ria foi desenvolvida utilizando AIML (Artificial Intelligence Markup Language), que ? uma linguagem de marca??o pr?pria para constru??o de di?logos em chatbot. O texto supracitado foi dividido em 9 trechos menores e em cada um deles est?o atribu?das algumas perguntas estrat?gicas para provocar a curiosidade do leitor. As perguntas foram divididas e alocadas conforme a necessidade de cada trecho do texto. A pesquisa demonstrou que o agente conversacional cumpriu seu papel em rela??o ao di?logo sobre o texto proposto e contribuiu de fato para o entendimento. No entanto, s?o necess?rias algumas melhorias no intuito de otimizar a capacidade de di?logo e consequentemente a efic?cia da t?cnica. Assim sendo, busca-se com este trabalho instigar discuss?es e pesquisas sobre o uso de chatbots aplicados ? educa??o e no ensino das estrat?gias de leitura.Disserta??o (Mestrado Profissional) ?

This ability makes it ideal for applying the protocolized reading technique, which consists of asking questions about a text to assess the understanding of what has been read and to encourage the reader to make inferences and to make predictions about what may come next. This practice is a cognitive activity, which encourages the individual to become more qualified to build autonomously, independently and continuously their own knowledge. As this technique is conducted in person by a teacher, the general objective of this research is to apply the reading technique registered in a text through a chatbot. It is intended to investigate the possibility of using this tool in the practice of protocol reading, identifying the main advantages and disadvantages and how it can contribute to the process of building text knowledge. The chatbot proposed in this work, entitled Professor Vit?ria, was programmed to apply the Protocoled Reading technique in the text ?A Armadilha?, by Murilo Rubi?o. Professor Vit?ria was developed using AIML (Artificial Intelligence Markup Language), which is its own markup language for building dialogues in chatbot. The aforementioned text was divided into 9 smaller sections and in each of them some strategic questions are attributed to provoke the reader?s curiosity. The questions were divided and allocated according to the need for each part of the text. The research demonstrated that the conversational agent fulfilled its role in relation to the dialogue about the proposed text and contributed in fact to the understanding. However, some improvements are necessary in order to improve the capacity for dialogue and consequently the effectiveness of the technique. Therefore, this work seeks to instigate discussions and research on the use of chatbots applied to education and the teaching of reading strategies

Collision avoidance system with obstacles and humans to collaborative robots arms based on RGB-D data

The collaboration between humans and machines, where humans can share the same work environment without safety equipment due to the collision avoidance characteristic is one of the research topics for the Industry 4.0. This work proposes a system that acquires the space of the environment through an RGB-Depth sensor, verifies the free spaces in the created Point Cloud and executes the trajectory of the collaborative manipulator avoiding collisions. It is demonstrated a simulated environment before the system in real situations, in which the movements of pick-and-place tasks are defined, diverting from virtual obstacles with the RGB-Depth sensor. It is possible to apply this system in real situations with obstacles and humans, due to the results obtained in the simulation. The basic structure of the system is supported by the ROS software, in particular, the Movelt! and Rviz. These tools serve both for simulations and for real applications. The obtained results allow to validate the system using the algorithms PRM and RRT, chosen for being commonly used in the field of robot path planning.This work has been partially funded by Junta de Castilla y León and FEDER funds, under Research Grant No. LE028P17 and by "Ministerio de Ciencia, Innovación y Universidades" of the Kingdom of Spain through grant RTI2018-100683- B-I00.info:eu-repo/semantics/publishedVersio

Thermographic imaging in sports and exercise medicine: A Delphi study and consensus statement on the measurement of human skin temperature

This is an accepted manuscript of an article published by Elsevier in Journal of Thermal Biology on 18/07/2017, available online: https://doi.org/10.1016/j.jtherbio.2017.07.006 The accepted version of the publication may differ from the final published version.© 2017 Elsevier Ltd The importance of using infrared thermography (IRT) to assess skin temperature (tsk) is increasing in clinical settings. Recently, its use has been increasing in sports and exercise medicine; however, no consensus guideline exists to address the methods for collecting data in such situations. The aim of this study was to develop a checklist for the collection of tsk using IRT in sports and exercise medicine. We carried out a Delphi study to set a checklist based on consensus agreement from leading experts in the field. Panelists (n  =  24) representing the areas of sport science (n = 8; 33%), physiology (n = 7; 29%), physiotherapy (n = 3; 13%) and medicine (n = 6; 25%), from 13 different countries completed the Delphi process. An initial list of 16 points was proposed which was rated and commented on by panelists in three rounds of anonymous surveys following a standard Delphi procedure. The panel reached consensus on 15 items which encompassed the participants’ demographic information, camera/room or environment setup and recording/analysis of tsk using IRT. The results of the Delphi produced the checklist entitled “Thermographic Imaging in Sports and Exercise Medicine (TISEM)” which is a proposal to standardize the collection and analysis of tsk data using IRT. It is intended that the TISEM can also be applied to evaluate bias in thermographic studies and to guide practitioners in the use of this technique.Published versio

Burke’s grammar of motives was used to classify the attributed source or justification for a potential preference for each preference block. To compare the MIPPs, 13 patients’ encounters with their clinician were video recorded and subsequently analyzed by 4 coders using the final video coding scheme. Six of these patients were interviewed, and 7 surveyed, immediately following their encounters.Results: For videos, an average of 66 (range 33– 106) sets of utterances potentially indicating a patient preference (a preference block), surveys 33 (range 32– 34), and interviews 25 (range 18– 30) were identified. Thirty-eight unique themes (75 subthemes), each a preference topic, were identified from videos, surveys 19 themes (12 subthemes), and interviews 39 themes (54 subthemes). The proportion of preference blocks that were judged as expressing a preference that was clearly important to the patient or affected their decision was highest for interviews (72.8%), surveys (68.0%), and videos (27.0%). Videos mostly attributed preferences to the patient’s situation (scene) (65%); interviews, the act of receiving or living with SCS (43%); surveys, the purpose of SCS (40%).Conclusion: MIPPs vary in the type of preferences identified and the clarity of expressed preferences in their data sets. The choice of which MIPP to use depends on projects’ goals and resources, recognizing that the choice of MIPP may affect which preferences are found.Keywords: patient preferences, decision making, regulatory, preference identification, preference elicitatio

Uso de nanobast?es de ouro para o desenvolvimento de aulas pr?ticas de nanotecnologia.

Use of gold nanoparticles functionalization experiment was conducted in a biotechnology summer course at UFOP as a model for the introduction of the laboratory practice in nanotechnology for postgraduate courses in the areas of chemistry and biotechnology. The gold nanorods were synthesized by the seed method and then, functionalized with anti-IL-6 antibodies using the reagents EDAC/NHS and polyethyleneimine (PEI). This nanocompound was tested against the binding with the specific antigen (IL-6) and changes in the longitudinal plasmon absorption spectrum showed the coupling efficiency, which was also verified by the decrease in zeta potential. The experiment was satisfactory, with a positive feedback from participants, and could be implemented in nanotechnology practical classes from postgraduate courses, as a way for improve education in the emergent area of nanobiotechnology

Estratégias de coping utilizadas por familiares de indivíduos em tratamento hemodialítico

This descriptive, qualitative study aims to identify the coping strategies used most by the family members of patients with chronic kidney disease receiving hemodialysis. The data were collected through interviews, with the Coping Strategies Inventory questionnaire administered to ten family members, and were submitted to descriptive statistics and to thematic content analysis. The strategy used most was escape-avoidance, demonstrating that the family members prefer not to face the situation. The second most-used strategy was social support, ratified by the fact that they stated that they talk with other persons and professionals, seeking information about the problem, and because they accept the support received positively. The third was problem resolution, represented by the attitude of accepting responsibility for the care, either through strong affective bonds or through a feeling of responsibility established prior to the disease. The families use coping strategies of different intensities, while, nevertheless, indicating involvement and major participation in the care for the patient.Estudio cualitativo, que trató de identificar las estrategias de afrontamiento empleadas por las familias de los pacientes con insuficiencia renal crónica en hemodiálisis.
