This work was based on a case study of improvement of the warehouse layout of a multinational automotive glass sector, located in the State of Sao Paulo. The aim was to propose a layout template to be more effective and besides optimizing production would also promote an increase in warehouse packaging capacity for metal containers containing glasses, thus reducing operating costs. To achieve the desired purpose, it was developed two layout proposals and to this end inventory management tools have been used, such as ABC curve and the Spaghetti Diagram, and other concepts of Packaging Engineering and Logistics. By the end of this work, it was obtained as a result, a project in which it was possible to rearrange the packages according the demand, and the developed changes became the most efficient layout both in storage capacity as well as in the internal drive

Thinking about improving public education in Brazil means thinking not just what we wish to develop competencies and skills in individuals, but understands clearly identify the type of citizens who are training and what kind of society we want for the future. So if there are social and cultural changes they should have their comtraponto within the classroom considering education steeped in culture and therefore in the forms of modern communication. The challenge for school education is to show the students inside the classroom, as will be outside.

Thinking about improving public education in Brazil means thinking not only on what we wish to develop, skills and abilities in individuals, but understand and clearly identify the type of citizens we are devoloping and what kind of society we want for the future. In this context it is important to note that the practice in the classroom today can not be considered without regard to education steeped in culture and, therefore, in the forms of modern communication. So if there is a crisis in education, it can not be solved only within the classroom. The challenge for school education is to show students within the classroom how they will be out of school. Quality education is a blueprint for the future, to the unknown, to a world we do not know now. In this sense, to direct the education only for the labor market is a mistake, because the market is so today, but may be another in ten or fifteen years. Precisely because we do not know what are the requirements for citizens of the future, we must focus on what is essential in the formation of our youth. Is essential then to understand the ideas, learn to discuss them, argue and learn to recognize the role of technology in social and cultural evolution of mankind.

After years of stagnation, the naval construction industry in Brazil has been experiencing a period of recovery caused by investments in the oil and gas sector and the implementation of governmental programs that aimed to regenerate it. However, efforts in learning and innovations are needed in order to reinsert the country in this activity and achieve international levels of competitiveness. Based on literature about learning processes and continuous improvement practices and their impact in the innovative and productive processes, this paper aims to identify the main tendencies, mechanisms and procedures to improve the construction and management processes in the Brazilian naval construction industry. The methodology used for the data analysis classifies obtained information from magazines and annals of congresses of the sector, according to the established analysis categories (phenomena). Such categories study information related to the productive and technological processes of the industry, the main internal and external relations of the industrial park, the management of resources and processes, policies, investments, etc. The data was collected in the period 2004-2010, and more than 500 registers that show a dominance of the investment phenomenon, especially in the increase of productive capacity, were catalogued. In addition to this, there is evidence of modernization in the manufacturing plan and the equipment, diverse forms of cooperation, implementation of human resources management practices and engineering or processes and products. Hence, a process of catching up governs and is guided by modernization and increase training in this industry.

This paper reports the results of an extension project carried out at Unesp/Veterinary Medicine course in Araçatuba city with milk farmers of the region. The aim of the project was to supply information to farmers concerning to good quality milk production and, at the same time, to follow up the evolution of milk quality parameters, according to the current Brazilian legislation. Every 45 days, approximately, lectures were presented to milk farmers in Araçatuba city region, approaching chemical and microbiological composition of milk, prevention and detection of mastitis, hygiene proceedings in milking and conservation of milk, cleaning and sanitization operations of facilities and equipments and prevention of adulteration. During the intervals between lectures, milk samples were collected from collective milk cooling tanks and analyzed for microbiological, hygienic and physicochemical tests. The main inadequacies in milk quality were high total bacteria and somatic cells counts, low solids contents and water addition. These problems did not proceed to betterment during the project time. So, it was concluded that the time for instruction of farmers was not enough for a progress in the quality of the milk produced in the region, pointing out the need in continuing this kind of work.

As atuais estratégias de formulação exigiram a aplicação de novas ferramentas computacionais, que utilizam a modelagem matemática, dando suporte na tomada de decisão para uma nutrição de precisão. Por este motivo, destaca-se a programação não linear, que não visa apenas formular uma dieta que atenda as necessidades do animal, segundo o custo mínimo, mas também maximizar a margem de lucro. Assim, o presente trabalho teve como objetivo validar a utilização do modelo/princípio não linear (PNL), com maximização do retorno econômico, através de estimativas de desempenho das aves e dos custos da ração, segundo a variação de preço do kg do frango de corte (preço médio histórico de 2009 e 2010), as fases de criação e do sexo. Para tanto, foram utilizados 480 pintos de corte, 240 machos e 240 fêmeas de mesma linhagem (Cobb 500), no período de 1 a 56 dias de idade. O delineamento experimental foi inteiramente ao acaso, totalizando 6 tratamentos (aumentado ou diminuído em 25% ou 50% o preço médio histórico), com 4 repetições e 10 aves por parcela experimental. As aves foram alimentadas ad libitum com água e rações experimentais, formuladas à base de milho, farelo de soja, óleo de soja, suplemento vitamínico e mineral, calcário e fosfato bicálcico. Foi avaliado o desempenho (ganho de peso, consumo e conversão alimentar), consumo total energético e lucro nas diferentes fases (inicial, crescimento e terminação). O consumo de ração mostrou diferença significativa (P<0,05) entre as dietas que foram formuladas segundo o princípio não linear e linear. O consumo total energético foi significativamente influenciado (P<0,05) tanto pelo princípio de formulação como pela variação do preço histórico do frango, sendo o esperado, uma vez que essa condição é que viabiliza a aplicação do modelo para máximo lucro. Quanto ao lucro foi demonstrado que o princípio de formulação não linear permite minimizar as perdas significativamente (P<0,05), principalmente em condições desfavoráveis do preço do frango no mercado. Conclui-se que a programação não linear favorece a nutrição de precisão, partindo de um principio que este método oferece novas oportunidades para a produção de aves e melhorias de rentabilidade.
