O princípio constitucional da eficiência aplicado à outorga e à cobrança da água produzida na exploração petrolífera

Water production is unavoidable during a petrol well s lifetime. The amount of produced water associated with oil varies a lot. It can reach values which account to 50% in volume up to nearly 100%, at the end of the well s economic life. It could be verified that, once the water reaches the productive wells, there must be a management of this produced water. Its destiny is defined after a precise study, after which the best option is chosen between relieving it into the environment, re-injecting it into the producing container or disposing it into non-producing formations. Whichever option is made by the involved professionals, after the necessary analysis, it shall consider, besides the technical and economical aspects, also the alternatives which entail less environmental impact. The purpose of the present research is to conduct a study about the application of the constitutional principle of efficiency on the instruments worked out by the public administration on water management, specifically the water use licence and charging for the use in the management of water resources applicable to water production at the petrol wells. In this attempt, before entering the proper approach of the efficiency of the mentioned instruments, it was necessary not only bring to light the doctrinal perception about the constitutional principle of administrative efficiency, but also make some considerations concerning to the structure of the national water resources management, set by the Federal Constitution (1988) and the federal legislation (9433/97)

Gestão de estoques: uma proposta de reposição contínua para material médico hospitalar e medicamentos em um hospital universitário federal do estado do Rio Grande do Norte

The inventory management in hospitals is of paramount importance, since the supply materials and drugs interruption can cause irreparable damage to human lives while excess inventories involves immobilization of capital. Hospitals should use techniques of inventory management to perform replenishment in shorter and shorter intervals, in order to reduce inventories and fixed assets and meet citizens requirements properly. The inventory management can be an even bigger problem for public hospitals, which have restrictions on the use of resources and decisionmaking structure more bureaucratized. Currently the University Hospital Onofre Lopes (HUOL) uses a periodic replacement policy for hospital medical supplies and medicines, which involves one moment surplus stock replenishment, the next out of stock items. This study aims to propose a system for continuous replenishment through order point for inventory of medical supplies and medicines to the hospital HUOL. Therefore, a literature review of Federal University Hospitals Management, Logistics, Inventory Management and Replenishment System in Hospitals was performed, emphasizing the demand forecast, classification or ABC curve and order point system. And also, policies of inventory management and the current proposal were described, dealing with profile of the mentioned institution, the current policy of inventory management and simulation for continuous replenishment order point. For the simulation, the sample consisted of 102 and 44 items of medical and hospital drugs, respectively, selected using the ABC classification of inventory, prioritizing items of Class A, which contains the most relevant items in added value, representing 80 % of the financial value in 2012 fiscal year. Considering that it is a public organization, subject to the laws, we performed two simulations: the first, following the signs for inventory management of Instruction No. 205 (IN 205 ), from Secretary of Public Administration of the Presidency ( SEDAP / PR ), and the second, based on the literature specializing in inventory management hospital. The results of two simulations were compared to the current policy of replenishment system. Among these results are: an indication that the system for continuous replenishment reorder point based on IN 205 provides lower levels of safety stock and maximum stock, enables a 17% reduction in the amount spent for the full replenishment of inventories, in other words, decreasing capital assets, as well as reduction in stock quantity, also the simulation made from the literature has indicated parameters that prevent the application of this technique to all items of the sample. Hence, a change in inventory management of HUOL, with the application of the continuous replenishment according to IN 205, provides a significant reduction in acquisition costs of medical and hospital medicine

Planejando com lean construction: diretrizes para implementação da construção enxuta em obras

Nowadays lives up in an era of tight credit caused by the global financial crisis, as occurred in the past, it is the responsibility of various sectors and segments of society find ways to reinvent itself. In this context, Lean Construction presents itself as a strong alternative production management for companies in the construction segment. Arising out of lean thinking that originated in Japan in the postwar period and has spread around the world in times of extreme scarcity with the oil crisis. In practice the Lean Construction is a philosophy that seeks to improve the process of production management, maximizing the value of the flow from the customer's perspective through the elimination of losses. And thrives in environments and cultures that consider the scarcity of resources like something natural, applying both the macroeconomic crisis as in times of prosperity. The Planning and Production Control - PCP presents itself as a fundamental building block for companies to protect themselves in the face of economic fluctuations, seeking for their survival and success in the competitive market. Motivated by the lack of discussion of the topic in the local academy, and for the identification of 93.33% of construction companies that do not make use of methodological tools for PCP in the state, this dissertation aims to study and propose the implementation of lean construction in methodology of planning projects implemented on construction sites. This characterized the management system, of the production of a construction company, pointing out the main causes of ineffectiveness related to consequent low performance of one of his ventures. In sequence, the PCP was implemented with the use of tools to serve the principles of lean construction. This being monitored through indicators that provided managers managerial view of process of actions control and production of protective mechanisms. All implementation guidelines and application of this management model, were exposed in a simplified way, practical and efficient, in order to break the resistance of new practices and old paradigms in the industry.
