The purpose of this work was to encourage the adoption of the concept of Circular Economy by the companies regardless of your size in order to reduce environmental impact and help to avoid the malefic effects produced by the tailings discarded by the majority of the companies. This research was based on an extensive literature review and on the formulation of a case study, which was implemented and fully assisted by the Cosmetic Bio Phito Therapeutical Company. Using the assistance offered by the Enterprise Resource Planning tool (ERP), it was possible to infer a mere substrate whose only purpose was to support the raw material that would effectively be used to an applicability that, besides being profitable, brought circularity to the operational flow. The results obtained with the implementation of the Circular Economy brought to the company that was studied the opportunity to avoid inadequate waste management, in addition to a financial savings of around U$ 2,000 per month due the reduction of expenses with a material that, instead of being improperly discarded, was reprogrammed for practical use, through recycling. The research was developed using the Problem Based Learning (PBL) approach and hands on activities during all the work.

The purpose of this paper is to present a conceptual model of engineering teachers’ necessary competencies in PLE developed by eight teachers from one of those three universities studied by Tavares & Campos (2013), who decided to prepare themselves for the PLE methodology new teaching roles, through a training program designed on the basis of PLE methodology itself, which would allow them to experience the PLE methodology from their students’ perspective. A synthesis on the teachers' perceptions about the training program, obtained through a Likert scale questionnaire, and confirmed through observation and unstructured interviews, indicated that a teachers' training based on th...

In the context of secondary education, DBL has been used as an educational form to teach sciences. However, there is little investigated empirically about the characteristics of design-based learning in higher education, and more specifically, in engineering study programs. The aim of this study is to examine whether the characteristics of design-based learning theorized along five dimensions, e.g. projects’ characteristics, social context, teachers’ role, assessment, and design elements are present in engineering education programs in international universities. For our comparative study we have selected different engineering study programs in three technical universities in The Netherlands, Portugal and in Brazil. We have conducted a quantitative survey to gather the teach...

The structure of the course is based on five thematic axis integrated in a five years course: Medical Images, Clinical Engineering and Health Management, Medical Electronics, Bio-informatics and Biomechanics and Rehabilitations Engineering. The five themes are structured in Central and Associated Modules treating the technical, ethics, human, legal, business, psychological and social aspects. In that methodology the students receive a problem based on a daily situation, creating a learning context. The problem is the fuel of the challenge and motivates the students to understand and solve it. The teamwork discussions as tutorial session use the previous knowledge to create a learning network. In this scene the learning occurs in co-operative mode not only to learn but in a modern perspective: ...

In addition to bringing physical and mental health benefits, physical activity has been used to prevent and improve ADHD comorbidities; however, its effectiveness has not been quantified. In this study, the effect of physical activity on children's attention was measured using a computer game. Intense physical activity was promoted by a relay race, which requires a 5-min run without a rest interval. The proposed physical stimulus was performed with 28 volunteers: 14 with ADHD (GE-EF) and 14 without ADHD symptoms (GC-EF). After 5 min of rest, these volunteers accessed the computer game to accomplish the tasks in the shortest time possible. The computer game was also accessed by another 28 volunteers: 14 with ADHD (GE) and 14 without these symptoms (GC). The response time to solve the tasks that require attention was recorded. The results of the four groups were ana...

This project was supported by four curricular units (UCs): General Chemistry (GC); Calculus (C); Introduction to Industrial Engineering (IIE) and Computer Programming 1 (PC1). In order to collect data on the perceptions of students regarding their participation and motivation on 2011/2012 edition, a questionnaire with 46 closed items and 3 open questions was developed and applied to 35 students and the results discussed on a final workshop. Based on the results of the research, the final workshop shows that the students recognize the benefits of Project Based Learning (PBL) as a learning methodology, its contribution and motivation to development of competences and skills for future career and the importance of teamwork. However, the findings showed that the roles of teachers and tutors must be reviewed as well as the grade's weight of project related with UCs. Furthermore, students also pointed out some additional constraints during the project, namely: time required for the project; the integration of UCs' contents in the project and the effort put in the project and its impact in final grades.

These initiatives are rather recent and mostly restricted at least in some courses of the specific engineering. Within the PBL line, other variations on the methodology have been developed. Eberlein et al. (2008) present the characteristics of three common methodologies used in teaching science, comparing and contrasting them in order to enable a possible choice or combination in particular situations. The three methodologies that these authors present are: Problem-Based Learning (PBL), Process-Oriented Guided Inquiry Learning (POGIL) and Peer-Led Team Learning (PLTL), all of them being based on active learning and student-centred.

Owing to the high density of multiple diffraction peaks in the indexing of the pattern, contrasting with the low density of experimental peaks, a procedure to correctly index peaks has first been applied. After the correct indexing, the peaks were selected taking into account their quality (adequate intensity and definition) and then classified in accordance with their suitability for the determination ofaorc. The azimuthal angular positions of classified peaks were applied to indexing diagrams in order to obtain sets of values for bothaandc. Weighted means of the sets give final values foraandc. In order to obtain more reliable final values an iterative process has been employed. A statistical analysis of data has also been employed to calculate uncertainties for the mean values found in the iterative process. After 12 cycles o...

While a detailed physical mechanism of the absorption phenomenon is considered irrelevant here, the main attention is given to the overall effects of absorption on the proposed earlier self-consistent model of X-ray scattering. In this model, we substitute a single dipole used in the original Ewald's papers by the plane of continuously distributed planes of dipoles, but we maintain his self-consistency principle as the main factor determining the entire scattering process. New aspects, diverging present approach from the commonly used, are following. Absorption takes place exclusively at the electron sites arranged in a set of dipole planes. The flux of photons incident on each dipole plane is divided into two branches. The first one, which suffers unknown frequency changes, is considered here redundant. It is defined by an introduced probability factor, separately given for each dipole plane. It can be proportional to the first or second power of the local EM intensity and defines the number of photons lost for diffraction event. The second branch is that of the unchanged wavelength. It is scattered under an exact satisfaction of Ewald's selfconsistency principle and produces the same overall scattering as for nonabsorbing crystals. It preserves conservation of energy for the not-absorbed portion of photons. Absorption and refraction in this model of scattering are distinct phenomena.

Definir o processo adequado para cada aplicação requer a previsão de quão elevada será a tensão gerada em função das variáveis do processo utilizado. A fim de conhecer os valores das tensões resultantes, é necessário medi-las, por exemplo, usando análise experimental de tensão, que consiste no uso de strain gauges para medir deformações em uma superfície. Logo, o objetivo deste artigo é apresentar o processo de desenvolvimento e aplicação de um kit didático educacional (KiDiTen®), versão II, automatizado, em conformidade com a formação por competência na pesquisa do ensino de Engenharia, utilizando conceitos de Física, Matemática e Teoria da Elasticidade, com o objetivo de levar o aluno ao conceito elementar da tensão mecânica, tensão elétric...

These competences will enable new engineers to apply learning resources in professional contexts with greater efficacy. Thus, these engineers will be closer to the needs of industry. A learning methodology that has been used in these contexts is Project Based Learning (PBL). This paper presents a learning process based on PBL concepts, in which five teams of 5 to 7 students of Industrial Engineering and Management from the University of Minho, Portugal, developed projects in interaction with companies during a semester. This project is supported by 5 courses of the 7th semester: Organization of Production Systems, Information Systems for Production, Integrated Production Management, Ergonomic Study of Workplaces and Simulation. The objective of the students' project is to make the analysis and present proposals for improvement of a part of the production system of a company. With the support of teachers, students should manage the interaction with an industrial company under the established partnership and present suggestions for improvements to their production system, considering contributions from the 5 courses of the semester. The aim of this paper is to describe the operational model of this PBL process, evaluate the results in terms of students' learning and in terms of the perception of industry, and finally make proposals for improving the model. The evaluation of learning outcomes is based on the analysis of students' project results, a questionnaire and a closing workshop of the project with students. The evaluation of the perception of industry partners is achieved using informal interviews with company representatives. The evaluation process shows that, from the participants' perceptions, students have developed the competences that are expected and, in general, the teams are motivated by the outcome of their projects. They referred that there should exist better mechanisms of differentiation of individual classifications within the team. From the point of view of industry, the results are considered good, but there is a tendency to propose a greater focus on the objectives and results of the project. Considering these results, a change to the model is proposed, in order to increase the direction of the project. The proposal organizes the project into two very distinct phases: (1) analysis and diagnosis phase; (2) improvement phase. This change would explore the contents and competences expected of all courses during the analysis and diagnosis phase, and in second phase, the project would focus on developing specific solutions for the enterprise.

In order to adopt the principles of the approach Project Based Learning (PBL) the professor whom teaches this course proposes the development of a project which the theme, in the two last years, was the Da Vinci’s Self-Supporting Bridge. The history tells that Da Vinci designed four types of bridges. The design of this bridge was the most simple and ingenious of them. The design of Self-Supporting Bridge was developed from 1485 to 1487 attending the request of his patron Cesar Borgia, and it was necessary simple assembly without woodworking skills by the troops. The design is held together by its own weight without requiring any ties or connections. The development of this project was part of the assessment process in the course. The student...

The traditional teaching of engineeringdoes not answer the new demands of professionals’ needsin this area. As such, new teaching tools andmethodology have to be adopted. Within this context, abiomedical engineering course was created at PUC/SPbased on PBL methodology. In this project the curricularorganization is no longer based on subjects, as thepriority has shifted to a multidisciplinary courseframework in inter and trans-disciplinary modules. Thecourse is structured to include five different thematicareas, which are dealt with progressively, as well ascomplement and integrate ways of learning over theperiod of the course.Index Terms ⎯ biomedical engineering course,engineering education, problem based learning, thematicareas.
