Cultura empresarial e reestruturação produtiva na indústria brasileira: o caso da Lupo S/A

Founded in 1921, the company currently known as Lupo S/A is one of the most ancient textile and clothing industries in Brazil. In this article we aim to describe the general lines of the trajectory of this family company, currently producing socks, nightwear and sports articles. The focus of this paper is on the analysis of some strategies used by the company along its formation and development process, and, particularly, the way these strategies made possible the productive restructuring associated to the overcoming of the strong crisis which began in the end of the 80's and early 90's, contributing to its recent consolidation in the clothing industry. The leading hypothesis of the study is that pioneering connected to a strong organizational culture that has been formed and constructed since its foundation and that was reestablished in a more recent management were the factors which were responsible for the advances able to generate an innovation environment in products as well as in processes and management. The theoretical reflection selected to subsidize the cognitive construction of the study of the company is based on the historical approach of the development of the textile industry in Brazil and in studies about the importance of the action of the entrepreneur, in the role of the organizational culture and of innovation to choose strategies in companies. The research involved the analysis of documents and data of the company, as well as interviews with directors and employees. The results show a traditional company model, but also show the presence of a very advanced entrepreneurial dynamic. Modern world – known as a fordist industrial model – could already be noticed in the company when this production pattern was not clearly defined yet in the Brazilian industry. Nowadays, the company faces the challenge of globalization and the open competition in the international market which brings the rivalry of the greatest and best globalized companies.

Prevalence and possible risk factors of peri-implantitis: a concept review

The purpose of this review is to estimate the prevalence of peri-implantitis, as well as to determine possible risk factors associated with its development in patients treated with oral implants. Although implant therapy has been identified as a successful and predictable treatment for partially and fully edentulous patients, complications and failures can occur. Peri-implantitis is considered a biologic complication that results in bone loss around implants and may lead to implant treatment failure. A great variation has been observed in the literature regarding the prevalence of peri-implantitis according to the diagnostic criteria used to define peri-implantitis. The prevalence ranges from 4.7 to 43% at implant level, and from 8.9 to > 56% at patient level. Many risk factors that may lead to the establishment and progression of peri-implantitis have been suggested. There is strong evidence that presence and history of periodontitis are potential risk factors for peri-implantitis. Cigarette smoking has not yet been conclusively established as a risk factor for peri-implantitis, although extra care should be taken with dental implant in smokers. Other risk factors, such as diabetes, genetic traits, implant surface roughness and presence of keratinized mucosa still require further investigation. Peri-implantitis is not an uncommon complication following implant therapy. A higher prevalence of peri-implantitis has been identified for patients with presence or history of periodontal disease and for smokers. Until now, a true risk factor for peri-implantitis has not been established. Supportive maintenance program is essential for the long-term success of treatments with oral implants. The knowledge of the real impact of peri-implantitis on the outcome of treatments with oral implants as well as the identification of risk factors associated to this inflammatory condition are essential for the development of supportive maintenance programs and the establishment of prevention protocols.
