Aprendizado autorregulado em contabilidade: uma análise comparativa entre discentes de modalidade presencial e a distância

This research has conducted a comparative analysis of the profile of classroom and distance Accounting students as to the use of self-regulated strategies in learning. Through the sample of 302 students from two private higher-education institutions located in Bahia, it was verified how the mode of teaching, the semester, the age and the gender can be associated with the use of self-regulated learning strategies. Data has been treated by means of tests of averages (t test), descriptive analysis and factor analysis. The results showed that the strategies most employed by accounting students were the setting of goals, planning and learning. When explaining self-regulated strategies, through the teaching, semester, age and gender modes, the results indicate that the averages are significantly different for teaching and age modes. The study contributes in the sense of rethinking the teaching-learning models based on the storage of information aimed at encouraging the development of autonomous skills that promote the permanent learning based on the grounds of teaching for learning or learning how to learn, which are characteristics indicated by international bodies and necessary for professional excellence.Esta pesquisa realizou uma análise comparativa do perfil de estudantes de Ciências Contábeis da modalidade presencial e a distância quanto ao uso de estratégias autorreguladas na aprendizagem.

Impact of defatting and drying methods on the overall liking and sensory profile of a cereal bar incorporating edible insect species

It is necessary to develop products with desirable sensory properties in order to increase the acceptance of insect-based products by Western consumers. In this work, the impact of defatting on the sensory properties of cereal bars with yellow mealworm (Tenebrio molitor) larvae, in addition to the impact of different drying methods and different species (T. molitor and house cricket Acheta domesticus) were assessed. A model cereal bar incorporating oats, dried and dehydrated fruits was developed as well as four additional formulations with insect flour: defatted (Soxhlet method with ethanol) mealworm (TM_D), microwave (TM_MW) or oven dried (TM_O) mealworm and oven dried cricket (AD_O). A panel of 99 consumers rated overall liking and willingness to buy (9-point scale), and profiled the bars using a Check-All-That-Apply ballot. The bars with defatted or microwaved mealworm had similar liking and willingness to eat scores in comparison with the control bar. Conversely, bars with oven-dried insects had worse evaluations and were associated with negative attributes related to odor and flavor, which were hampered by defatting or microwave-drying. This study highlights how different processing methods can be applied in order to increase the sensory liking of insect-based products and also provides information on their sensory characterization.info:eu-repo/semantics/publishedVersio

Obesidade, síndrome metabólica e atividade física: estudo exploratório realizado com adultos de ambos os sexos, da Ilha de S. Miguel, Região Autônoma dos Açores, Portugal

The purpose of this exploratory study was to observe the prevalence of Metabolic Syndrome and to examine the relationship between overweight and obesity (Body Mass Index ≥ 25 kg/m²), low levels of Physical Activity (less then 150 min moderated e/or vigorous Physical Activity/week) and the Metabolic Syndrome. The sample of this study comprised 115 adults (68 woman and 47 men) aged 34.6 ± 7.8 years, from S. Miguel Island - Azores - Portugal. Body Mass Index was used to evaluate overweight and obesity. Physical Activity was assessed by the International Physical Activity Questionnaire. The cluster (3 or more risk fators associated) used to define the Metabolic Syndrome was: fasting glucose ≥ 110 mg/dl, triglycerides ≥ 150 mg/dl, high-density lipoprotein cholesterol ; 102 cm for men and >; 88 cm for women, blood pressure ≥ 130 and/or 85 mm Hg. Our data showed that overweight and obesity are higher in men than in women. About 2/3 of men and women showed insufficient levels of Physical Activity. In men the prevalence of Metabolic Syndrome (17.1%) was significantly higher than in women (4.4%). All individuals with Metabolic Syndrome were overweight or obese. The less active individuals had a higher prevalence of Metabolic Syndrome. Body Mass Index was associated and correlated with all the risk fators of the Metabolic Syndrome. The results confirm the need of adoption of healthy life styles in order to prevent and treat Cardiovascular Diseases, in general and Metabolic Syndrome, in particular.O propósito deste estudo exploratório foi observar a prevalência da Síndrome Metabólica e verificar a sua associação ao excesso de peso (IMC ≥ 25 kg/m²) e à inatividade física (menos de 150 min de Atividade Física/ semana moderada e/ou vigorosa). Uma amostra de conveniência (68 mulheres e 47 homens), com uma média de idades de 34,6 anos, da ilha de S. Miguel - Açores participou neste estudo. O excesso de peso e a Obesidade foram calculados através do Índice de Massa Corporal. A Atividade Física foi avaliada através do International Physical Activity Questionnaire. A agregação de três ou mais dos seguintes fatores de risco, foi considerada como indicador da Síndrome Metabólica: glicemia em jejum ≥ 110 mg/dl, triglicerídeos ≥ 150 mg/dl, lipoproteínas de alta densidade ;102 cm nos homens e >; 88 cm nas mulheres, tensão arterial ≥ 130 e/ou 85 mm Hg. Os resultados mostram que o excesso de peso e a Obesidade são superiores nos homens em relação às mulheres. Cerca de 2/3 da amostra é insuficientemente ativa. Nos homens, a prevalência da Síndrome Metabólica (17,1%) é significativamente superior à das mulheres (4,4%). Todos os indivíduos da amostra com Síndrome Metabólica têm excesso de peso ou são obesos. Os indivíduos insuficientemente ativos registam uma maior freqüência da Síndrome Metabólica. Os resultados confirmam a necessidade da adoção de estilos de vida ativos e saudáveis como forma de prevenção e de tratamento de primeira linha das Doenças Cardiovasculares, em geral, e da Síndrome Metabólica, em particular

An expert system for supporting Traditional Chinese Medicine diagnosis and treatment

Portugal has recently become one the few European countries to fully acknowledge Traditional Chinese Medicine (TCM); this substantial paradigm shift calls for novel tools for TCM practitioners, students and patients alike. This paper describes an Expert System for supporting the TCM consultation process – both in terms of gathering and managing the patients’ personal and symptomatic data, and of obtaining accurate diagnoses and treatments under regulated and reviewed protocols. The proposed tool was designed and is being developed with the support of two TCM therapists, which act as experts and provide aid to the processes of building the knowledge base and the automatic diagnosis system. In terms of architecture, the current version of the framework includes a mobile client application for the Android platform, integrated with an online spreadsheet. A survey was conducted in order to assess some of the needs of the community of TCM practitioners, and allowed gathering information on their needs

Mobile robot competitions: fostering advances in research, development and education in robotics

Mobile robot competitions are events well suited to experimentation, research and development in many areas concerned with science and technology, ranging from material science to artificial intelligence. Aware of this fact, and for several years now, some Portuguese Universities have been involving some of their Engineering and Computer Science students in such contests, namely those of international level. The performance has been improving both in terms of the results and prizes obtained and the increasingly elaborate technical solutions developed by the teams. The importance recognised in these events has led the authors to submit to the Portuguese Government a proposal for an annual Festival of this kind in Portugal. This paper points out the advances in research, technology and education, which result from this type of events

The Importance of Subcontracting and Its Relationship With Lean Philosophy in Automotive Industry

The automotive industry represents one of the largest economic sectors in the world and most companies in this industry involve subcontracting in their strategy. However, subcontracting is one of the possible processes that can lead to inefficiencies for companies. Since lean arises as a response to the most varied problems of companies, the main goal of this work is to understand the importance of subcontracting in the automotive sector and to understand how lean and subcontracting are related. For this, an empirical study of papers and books related to these topics was performed, concluding that subcontracting is frequently used in the automotive sector, to obtain strategic advantages, and that it supports the foundations of the lean concept, as well as the lean can help manage subcontracting. The trade-off of the transfer of activities enables organizations to be flexible, lean and agile; they can then focus on their core activities, which generate more value, while the option to subcontract generates a significant reduction in costs by transferring non-core activities. In short, these two concepts are related to each other in the context of the automotive industry.info:eu-repo/semantics/publishedVersio

A Comparison of the Application of the SMED Methodology in Two Different Cutting Lines

Purpose: This study was carried out in a cork company and its purpose was to observe and analyze the practices and methods used during the tools/series change moments and to propose improvements and alternatives to these same procedures so that the time needed to carry out the setup is reduced by 15% in both lines. Methodology/Approach:The methodology included the following phases: 1st - historical data collection and setup video recording, 2nd - footage analysis and conduction of informal interviews with employees, 3rd - flow, Gantt, and spaghetti charts creation and making of an action plan based on the waste and improvement opportunities identified in video analysis, 4th - validation with the line workers of the new operating mode created with the Single Minute Exchange of Dies (SMED) tool and communication to the Maintenance department about their role in this project, 5th - making and placement of plasticized cards on the cutting lines to ensure that new operating mode is followed and carrying out the actions identified in the action plan. Findings: Throughout this project using observations, video recording and its subsequent analysis, as well as interviews to the workers operating in the line, it was found the existence of several actions carried out by them during the setups which did not add value to the product, lack of adequate tools for the work to be performed and lack of work tools in general Research Limitation/implication: The study was limited by the lines and products under study and by the duration of the curricular internship, which was about five months. Originality/Value of paper: The article demonstrates the added value in terms of product quality and production output rate that SMED methodology can bring to companies that adopt the lean philosophy and in particular this continuous improvement tool.The author Alexandre Silva would like to thank Amorim Revestimentos for the opportunity to carry out the project in its facilities, thank Filipe Ferreira and César Daniel for the moments of companionship and for the shared knowledge, thank Mr. Pedrosa and the entire Maintenance Department for their collaboration in this project, to thank the employees of the cut lines for their availability to clarify doubts, to listen and follow my ideas and to thank, namely, Professor José Carlos Sá for his guidance and availability.info:eu-repo/semantics/publishedVersio
