The proposal of this article is discuss about the concept of social responsibility in the context of the activity of Public Relations in order to verify how this concept is related to the notion of Peace Culture. It is a complex concept supported by the United Nations Educational, Scientific and Cultural Organization (UNESCO) which, among other objectives, seeks to interpret and also paid up organizational objectives to local and global demands by articulating social actions that lead to a sustainable development and management of cities. For this, we will defend the use of audiovisual resource for awareness of stakeholders as a strategic tool in Public Relations for the efficacy of topics related to "Sustainable Cities Program”, about which we will briefly discuss. The Program is a nonpartisan initiative that focuses on the sustainable management of cities so it functions as a tool that assists municipal managers in making strategic decisions.

The objective of this work was to compare the performance of a tractor equipped with used and new bias-ply tires (63.4% and 41.2%, front and rear tire waste, respectively), in three surface conditions: tillage soil, vegetal covered soil and firm soil. Field data were collected to calculate: forward speed, front and rear slippage tires, drawbar pull, available power at drawbar bar and fuel consumption. Results showed that both, tires and soil conditions, changed tractor capacity on developing drawbar traction. The worst performance was observed on tillage soil. The best performance of the tractor was observed at firm soil track. On the track with tilled soil, results showed that the forward speed was the lowest among the three soil conditions due to the front and rear slippage tires which was higher than vegetal covered and firm soil tracks. Fuel consumption results showed higher values on tilled tracks when compared with firm and vegetal covered tracks. The fuel consumption levels evaluated on bias-ply tires lead to significant changes on tractor’s performance at tilled soil, indicating that, at this condition, it’s necessary to replace the used tires by new tires. For vegetal covered soil operations, and also on firm soil conditions, used tires, at studied levels, indicated that these tires might still be used without tractor performance changing.

Em todo o mundo, são realizadas mais de 230 milhões de operações por ano e as complicações cardíacas são as causas mais comuns de morbidade e mortalidade pós-operatórias. Com o aumento da expectativa de vida da população mundial, um número crescente de pacientes com múltiplas comorbidades tem sido submetido a operações não cardíacas. Em consequência, é esperado um aumento de complicações cardiovasculares associadas a tais procedimentos e o infarto agudo do miocárdio (IAM) perioperatório poderá se tornar um problema frequente. No Brasil, o número de operações não cardíacas também está aumentando, sendo realizadas aproximadamente três milhões de cirurgias por ano. Apesar dos avanços nas técnicas cirúrgicas e anestésicas, a mortalidade e o custo relacionados a estes procedimentos também estão aumentando, sendo fundamental o desenvolvimento de estratégias para a redução da mortalidade. A ocorrência de um IAM perioperatório prolonga a necessidade de terapia intensiva, a estadia hospitalar, aumenta o custo da internação e diminui a sobrevida a longo prazo. Esta revisão aborda a fisiopatologia, a incidência, o diagnóstico e o tratamento do IAM perioperatório, baseado nas evidências atuais.
