A gestão estratégica do conhecimento sob os parâmetros dos modelos de governance corporativa nas empresas com capital aberto

This article covers the concepts about the knowledge management practices aligned with corporate governance in the organizations opened capital, highlighting the importance attached to these types of management assistance in the conduct of business organizations. Highlights the points that still have gaps existing in governance organizations models and proposes a discussion of what remains to be done by proposing the use of knowledge management models as a tool to aid the implementation of best governance practices. Through research conducted in a company with publicly traded and listed on Level 1 of corporate governance, it was possible to identify therelationship between knowledge management models aligned with corporate governance standards. A questionary that includes elements of corporate governancein line with the concepts and models of knowledge management was applied. After finding that there is strong alignment between knowledge management and corporate governance, we present the arguments about the contributions that this convergence can bring to the organization.

Disseminação da informação em empresas de capital aberto e os processos de mediação da informação

Corporate governance can be understood as management mechanisms that through external and internal controls are going to reduce the distance between minority stakeholders and the control power of the company. In that context, the information management, the information mediation and the information dissemination is very necessary, because the establishment of the good communication, quick, clear and voluntary, in order to establish a confidence climate in the relation of the company with the society, creditors, and collaborators especially with investors. In Brazil, the model created by the stock exchange of São Paulo called of new market , brings in his additional conduct rules purpose to them required by the Brazilian legislation and possessed like base the equity in the handling between part, the transparency in the disclosure of information and responsibility in the installment count. This article presents some considerations about the model of information management and accountability based on legal criteria, in additional standards of information disclosure, and the information mediation process relationship the corporate governança in the business environment.

Aplicações clássicas da técnica de espalhamento de raios-x a baixo ângulo em materiais nanoestruturados

The small angle X-ray scattering (SAXS) technique has been used with very much versatility and success in the structural characterization of nanostructured materials. The present work deals with a study of the principles of the SAXS technique and of some classical models employed in the structural characterization of nanostructured materials. Particularly, the study of the models and of the associated methodologies is applied to a set of samples of silica gels, of varied typical structures, prepared in the Laboratório de Novos Materiais of the Departamento de Física of the IGCE. The work discusses in an introductory chapter the principles of the SAXS technique and the foundation of classical models often used in the structural characterization of materials. The classical models and the associated methodologies were applied to a variety of silica gel structures. The studies include: i) the scattering from a system of particles - Guinier's law; ii) the asymptotic scattering from a two-phase system - Porod's law; iii) systematic deviation from Porod's law - Surface Fractal; iv) heterogeneities in solids with random size distribution - DAB Model; and v) the scattering from mass fractal structures. The analyses were carried out from experimental SAXS data obtained in several opportunities at the Laboratório Nacional de Luz Síncrotron (LNLS)

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

Estudo comparativo do desempenho empresarial no Brasil e na China no período de 2005-2009: uma análise de empresas de capital aberto do setor de siderurgia

A teoria em finanças tem evoluído cada vez mais aproximando a teoria financeira às práticas reais adotadas nas empresas e nos mercados financeiros. A partir de Modigliani e Miller, que contribuíram para o ramo das finanças com a teoria da Irrelevância Financeira, o caminho se abriu para uma série de debates a cerca da importância das variáveis financeiras na determinação do valor da empresa. Foram levantados questionamentos a respeito da perfeição dos mercados e apresentado argumentos como a assimetria de informações, os custos de agência, a restrição financeira e outras implicações à teoria do investimento. Atualmente o que se sabe é que o fator investimento está altamente ligado às finanças e, portanto, relaciona-se com os meios de financiamento presentes no mercado e com a organização interna e financeira das firmas, esse ramo de estudo recebe o nome de Finanças Corporativas. Diante da teoria financeira, o objetivo é analisar a indústria siderúrgica de duas economias atualmente em destaque, Brasil e China através da análise econômico-financeira de quatro empresas de capital aberto do setor: Gerdau, Usiminas, Baosteel e Masteel. Cabe destacar que a indústria siderúrgica é base para outras indústrias, como construção civil, automóveis, máquinas, entre outros e, por isso, é tida como sinalizadora do desenvolvimento econômico de um país, assim também, o Brasil e a China são caracterizados como grandes potenciais emergentes e fontes de atração de investimentos internacionais

Concepção e Implementação de um Sistema de Controle de Arborização Urbana através da Integração de Softwares Livres e de Código Aberto

Suitable computacional tools allow to build applications that can link information to its physical location, and represent them into visual and interactive schemes, e ectively reaching the power of visual comunication. This leads the user to synthesize information in a simple and e cient way. These applications are linked to the de nition of Geographic Information System (GIS). GIS are comprised by many concepts and tools, which have the main purpose of collecting, storing, viewing and processing spatial data, obtaining the information needed for decision making. Within this context, this paper presents the Conception and Implementation of a Control System for Urban Forestry through Integration of Free and Open Source Software. This conception arose from the need of an Environmental Project developed by the Agriculture's House of the city of Regente Feij o, which has as main objectives cataloging and management of urban a orestation of the municipality. Due to this diversity of concepts, the challenge in building this system is the integration of platforms that are involved in all stages: collecting and storage of data, including maps and other spatial information, operations on the stored information, obtaining results and graphical visualization of the same. After implementation, it was possible to provide for the system users an improvement in the capacity of perception in the information analysis and facilitate the process of decision making

Alterações dentoesqueléticas verticais e horizontais induzidas pelo ativador elástico Aberto de Klammt

The aim of this study was to evaluate the vertical and horizontal dentoskeletal changes induced by the Klammt Open Elastic Activator in the treatment of the Class II Division 1 malocclusion. The sample of 34 children was divided into two groups of 17 subjects each (ten girls, seven boys), matched by age and gender and with an initial mean age of 8.5 years. The data was analyzed using a Student's t-test for intragroup and intergroup comparison. The results showed that the appliance promoted dentoalveolar restriction of the maxilar growth within normal anteroposterior and vertical growth of the maxillary apical base; increment in the vertical displacement the mandibular symphysis associated with normal horizontal growth of the mandible; palatal tipping of the upper incisors; restriction of the anterior migration of the upper molars; greater eruption pattern and normal anterior displacement of the lower incisors and molars. It was concluded that Klammt appliance induce changes that are predominantly horizontal dentoalveolar in upper arch and vertical dentoalveolar in lower arch and vertical skeletal changes in the mandible.
