A series of methods and techniques has gained prominence in the organizations that possess a standard of system for development of products - SDP in the conceptual phase of the project, as well as in redesign when necessary. The QFD, the Analysis of Kano and the Pugh Matrix are some examples of methods and used techniques to integrate methods in project. However, if one of the characteristics of methodology DFA is to reduce the number of assembly operations reducing the number of components and make the assembly operations easier to perform, this methodology can be applied in ergonomics, since it assists the design activity of work situations, specially in the stage of generation of alternatives and analysis of feasibilities for the simplification of the structure of the product. This way, the main contribution of this research is to demonstrate that the use of the Design for Assembly tool can be extended in situations of redesign of products for attainment of technical solutions in the situations of ergonomic interventions, or even though in the conceptual phase of a new project, where the ergonomics will be considered inside of vision DFA. The accomplishment of the Workplace Ergonomic Analysis - WEA associated with the use of the design for assembly - DFA tool for technical solutions in ergonomic interventions can be a possibility for design teams that are looking for associate design and ergonomics.
Utilização de conhecimento de senso comum no planejamento de ações de aprendizado apoiado por computador
(Universidade Federal de São Carlos, 2007-07-06) Carvalho, Aparecido Fabiano Pinatti de; Silva, Junia Coutinho Anacleto; https://lattes.cnpq.br/6200743168568684; https://lattes.cnpq.br/5938256745631798
Common sense and learning. How can this kind of knowledge, which refers to the knowledge shared by the majority of people who are inserted into the same social and cultural context, support teachers to plan learning activities which fit to pedagogical issues, important to an effective learning? How can computational technologies make viable the use of this kind of knowledge by teachers, supporting them to make decisions during the planning of tasks of a specific learning activity? This research answers these questions (i) evaluating how common sense knowledge is related to Learning Theories, proposed by Paulo Freire, Célestin Freinet, David Ausubel and Robert Gagné, authors who are renowned in the pedagogical area; (ii) exploring how computational technologies can be used to collect and present this kind of knowledge to teachers; (iii) suggesting ways to teachers use it, in order to reach pedagogical issues; and (iv) showing the use of a framework to plan learning activity, considering the suggestions of using common sense to plan learning activities, made in this research. The suggestions can be summarized in supporting teachers: (a) to decide the detail level of the learning activity topics, based on the knowledge that the target group demonstrates to have well formalized, as well as on the misunderstandings that it makes about other topics, and on the information that it forgets to mention in the knowledge base; (b) to identify topics of general interest to be taught; (c) to identify a common vocabulary used by the target group; and (d) to support the use of cognitive operators. For this purpose, it is used computational resources, developed in the context of Artificial Intelligence researches, to plan a learning activity in the in the health domain, specifically in the domain of home caring a sick person. Teachers from the Nursing Department of the Federal University of São Carlos use these resources to plan a learning activity, taking into account the common sense knowledge acquired from the Brazilian population, stored in the knowledge base of the Brazilian Open Mind Common Sense Project, developed by the Advanced Interaction Laboratory from the Computer Department of the same University in partnership with the Media Laboratory of the Massachusetts Institute of Technology. The learning activity main goal is to prepare Nursing learners to interact with the population, from which the knowledge was acquired, orienting people from that population about the procedures that might be taken, in order to home care a sick person. The results obtained are critically analyzed and they point to the validity of the suggestions of using common sense to plan learning activities made in this research
Análise ambiental integrada do componente solo como subsídio para avaliação da sustentabilidade da Bacia Hidrográfica do Rio Tenente Amaral em Jaciara - Mato Grosso - Brasil
(Universidade Federal de São Carlos, 2007-07-06) Santos, Vanderley Severino dos; Lorandi, Reinaldo; https://lattes.cnpq.br/7794241793056671; https://lattes.cnpq.br/3023826124411117
This work has as objective to to apply and compare five different methodologies of environmental analysis and to produce maps thematic that: they characterize the environment, they evaluate the susceptibility and the potential to the laminate erosion, they to determine potential the environmental fragility and emergent, they evaluate the vulnerability to the erosion, esteem the average losses of soil and the production of sediments and thus they evaluate the environmental sustainable of the Water-Basin of the River Tenente Amaral in Jaciara, Mato- Grosso, Brazil. For the present study one uses of techniques of Geoprocessing and cartographic data soil, geology, the geomorphology, the climate, the vegetation and the use of the soil of the region of the Basin, converting them for the digital format. The results demonstrated that the studied area presents high percentage of human activities (84%) predominating the sugarcane cultivation. The soil predominance of type LATOSSOLOS and NEOSSOLOS QUARTZARÊNICOS in soft relief was distinguished in the region proceeding from the claysand layer unconsolidated sediments of the Cochoeirinha Formation that if presents with bigger area of occurrence in the place. With the application of the methodologies for the study of the area it was verified that approximately 55% of it present average the high potential' to the laminate erosion; natural conditions of strong instability `the very strong one'; balance in the occurrence of processes of morphogenese and pedogenese; average losses of high soil had been classified enter `and very high' e, in relation to the production of sediments, was verified that the esteem production more is accented in the places where the use of the soil is intensive, being able to reach up to 0,433 t.ha¹.
