Criação e implantação de procedimentos logísticos em uma indústria de móveis: estudo de caso

The Brazilian construction is with high production which resulted in many service industries and also for businesses that work in conjunction with it. For the furniture industries would not be different, since they are intimately involved with the construction. To meet the demand for furnishings in Brazil, some clusters of industries have developed in recent years, as in the case of Uba (MG), Arapongas (PR) and Bento Gonçalves (RS). For industries sector can always increase its production combining quality and customer satisfaction, is necessary for their production procedures are studied and improved every day. The aim of this research is to propose a solution for simple information system involving the issue of tracking parts of the furniture produced in an industry custom furniture that depend on outsourced services. The research occurred during four months of the year 2013 for the observation of the production of the industry, where possible observing interference could be carried out with the aim of obtaining improvements in the production line. It is concluded that control of the finished product in a custom furniture industry is a very complex work, because the information system must transmit information faithful, which has not happened formerly, but after the implementation of the identification system was significant improvement the transfer of information between sectors mounts internal and external furniture

Evolução da dívida pública mobiliária interna e o gasto social da União nos anos de 2003 a 2010

This study presents the trajectory of domestic federal public debt from Brazil in the years 2003 to 2010. Scales the amount spent on financial burden to pay the debt in relation to what was spent on items related to social development, health, education and welfare. The study concludes that Brazil despite an increase in social spending, with effective results, expenditures for the cost of domestic federal debt were much higher than social spending. The numbers were expressive in the maintenance of debt and very tiny in relation to social spending

Cogeração de energia com motores de combustão interna

The tertiary sector is largely responsible for the growth of electricity consumption in Brazil. The large commercial and public buildings, hypermarkets and shopping centers stand out as major consumers of electricity for lighting, power and thermal energy. Brazil presents significant potential for the deployment of small cogeneration plants, especially in the tertiary sector. Allied to this, the possibility of natural gas supply and the growing demands in favor of maintaining and preserving the environment favor the implementation of cogeneration plants. In this context, this paper presents a technical and economic analysis of installing a cogeneration plant using internal combustion engine with natural gas in a mall

Comunicação interna e gestão de pessoas: um olhar para as relações humanas nas organizações

The main purpose of this study is to show how internal communication can be allied to people management in the process of transformation of the organizations. It is known that the advent of new technologies and the information age, consequences of globalization, are provoking deep transformations in organizations and reaching people too. This way there is the human and the social issue that goes beyond the race for profit. The new forms of management are becoming increasingly concerned with the value of human being and communication professionals, more specifically public relations, can facilitate processes and significantly improve the relationships towards positive results

Estudo da modificação do ângulo do conjunto cilindro-pistão em motores de combustão interna

The aim of this study is to present those who are interested in mechanical engineering, specifically automotive engineering some ideas for improvements to the current concept of internal combustion engines. It is not intenden to change totally the design of the engine known today, but to exame the feasibility of reducing a small waste generated with the current positioning of the cylinder-piston assembly. The proposal solution consists in modifying the tilt cylinder-piston assembly in the angle between the rod and the cylinder axis. This inclination causes all the force generated in the combustion process within the cylinder is delivered to the rod.Delivery force is the made in the rod longitudinal direction and not on the axis of the cylinder, preventing the occurrence of a breakdown of the force generated in the combustion process. After analyzing the idea of repositioning the piston-cylinder assemble, it is concluded that the change has a positive result in the process of harnessing the power generated in the com bustion, but its not feasible due implementation to low gain presented in this study

Modelo de regressão logística aplicado ao estudo epidemiológico do HIV/AIDS na cidade de Campinas-SP

A compreensão da epidemia do HIV e da AIDS em suas diferentes dimensões socioeconômica, cultural, biológica e política entre outras, representa um grande desafio para a Saúde Pública no Brasil e no mundo, desde o seu surgimento a cerca de duas décadas. Tanto na magnitude da propagação do HIV quanto na mortalidade por AIDS, reflete-se a crescente desigualdade entre países desenvolvidos e em desenvolvimento. Na medida em que se acentuam as diferenças de acesso ao tratamento, diminui a mortalidade por AIDS nos países mais ricos e aumenta nos países mais pobres, exceção feita ao Brasil, um dos poucos países que adotaram a política de distribuição gratuita de anti-retrovirais. Segue, no desenvolvimento deste trabalho, a análise do perfil epidemiológico da doença no município de Campinas-SP de acordo com a evolução do tratamento disponibilizado pelo Sistema Único de Saúde (SUS), utilizando o método de Regressão Logística segundo variáveis consideradas relevantes para o estudo e com base em parâmetros estimados a partir dessas variáveis

Modelo de conjuntos fuzzy e de regressão logística para dados de obesidade

Obesidade e comumente definida como um excesso de gordura corporal, porém diante da dificuldade em mensurar tal gordura diretamente, esta tem sido definida como um excesso de peso mais do que um excesso de gordura corporal, que tem como desdobramento a ocorrência de doenças associadas e/ou prejuízos a saúde do indivíduo (4). Atualmente, o excesso de massa corpórea e verificado por meio de um Indice de Massa Corpórea (IMC), que considera o quociente entre o peso corporal (kg) e a estatura elevada ao quadrado (m2). Indivíduos com sobrepeso apresentam IMC de 25 at e 29; 9 kg=m2, e com obesidade apresentam IMC de 30 Kg=m2 ou mais, de acordo com a OMS (1). A identificação das causas da obesidade não é trivial e objetiva. Especialistas reconhecem que a obesidade e uma doença crônica, de difícil tratamento, denominada multifatorial, envolvendo em sua gênese diversos aspectos, entre eles: o consumo alimentar, aspectos ambientais, genéticos, psicossociais, entre outros. objetivo deste trabalho foi desenvolver um modelo baseado em teoria dos conjuntos Fuzzy para a classificação de obesidade levando em consideração as suas causas, e compará-lo com um modelo de regressão logística através da curva ROC. Para estudar as causas da obesidade na população de moradores da região do Distrito Sul de Campinas, foram coletados dados de uma amostra aleatória de 651 indivíuos, por meio de entrevista domiciliar. No primeiro estágio amostral, a partir do cadastro de domicílios residenciais dos agentes comunitários de saúde, foram aleatoriamente sorteados 920 domicílios (15% a mais do inicialmente previsto para cobrir perdas). Foram coletados dados de identificação geral, como: nome, idade, sexo, anos de escolaridade, tipo de ocupação e dados de consumo alimentar. O diagnóstico foi observado através do IMC. Num estudo preliminar, no modelo fuzzy foram consideradas como variáveis... (Resumo completo, clicar acesso eletrônico abaixo)

O local de nidificação do sabiá-barranco (Turdus Leucomelas) (Aves, Turdidae) afeta a temperatura interna do ninho durante a incubação e cuidado à prole?

Individuals of the species Turdus leucomelas are adapted to live in environments already modified by humans, thus obtaining reproductive success in their nesting in vegetation, as well as built their nests in human buildings. Nests found in buildings are often less camouflaged, making them more exposed to predators compared to nests built in vegetation; however the nests built buildings are common, indicating a possible advantage associated with these nests. By means of this idea if was assumed that a possible advantage to this construction in buildings is linked to a change in variation in the internal temperature of the nest during incubation and development of pups until they leave their nests. Accordingly, with the aid of iButtons and TidBits (temperature data loggers), the present study aimed to analyze the influence of the nesting site on how the temperature is kept, and how it changes in the microenvironment in which the nest is inserted, indicating potential benefits associated with that choice. In the samples found with the vegetation, temperature data showed a pattern of temperature of the microenvironment of the nests is not very stable, varying with ambient temperature, whereas in the samples found with the human constructions, the temperature data showed a pattern of temperature microenvironment nests more stable for a long time. When comparing the two environments which they settled nests, as well as the different times of day (daytime and nighttime), how the temperature was kept and pattern of change within the nest was significantly different (F=43.85, p<0.001), with higher and more constant internal temperatures in nests installed in construction, compared to vegetation. When observing periods of the day, it was found that in both environments the temperature inside the nest reached higher values and higher than the environment at night, coinciding with the rest of the female at night. Data may suggest changes in the...

Estudo da anatomia interna dos incisivos laterais superiores pelos métodos radiográficos digital e convencional

The maxillary lateral incisor has a very peculiar and internal morphology that can be influenced by the its external anatomy such as supernumerary roots and ruts deep root, which often hinders an effective endodontic treatment. Generally, this tooth have a single root with one root canal, but teeth with two to four channels can be found. The main canal can present ramifications such as accessory canals, laterals, collaterals, recorrents and apical deltas. All this factors interfere directally on endodonthics treatment. The objective of this work is a study of the internal anatomy of the maxillary lateral incisors by digital and conventional radiographics methods, comparing the results obteined by each method Six hundred upper lateral incisor were used in this study teeth of the collection of the Department of Anatomy ICT – UNESP. All the teeth were radiographed by vestibular face, using a digital radiographic unit(Dabi Atlante). After this step, all the teeth underwent by conventional radiographic technique(Kodak 2200) so that the results obtained were compared. To classify the channel system, it was adopted the classification of Pucci and Reig. All data obtained by digital technique were compared with those obtained in the conventional technique and were subjected to statistical analysis
