Reasons for technology-based companies contemplated by the first company program to seek ISO 9001:2008 certification
The search for implementation of Quality Management Systems aims to continuously improve their results. Thus, for the services and/or products offered to convey trust and credibility, they must be designed within appropriate norms and standards. In this sense, this study seeks to assess the reasons that induce incubated technology-based companies to seek adequacy of their quality management system to the NBR ISO 9001:2008 standard. Through an exploratory survey in twenty-six incubated technology-based companies, a twelve-question questionnaire proposed by Bhuiyan and Alam (2005) was applied. After analyzing the data, it is concluded that the reasons for adequacy of QMS to the NBR ISO 9001:2008 standard are: competitive advantage over competitors; consultant´s approach for implementation; improvement in product quality; and government funding for ISO 9001 certification. It is found that the consultant´s approach stands out as a strong reason for seeking the adequacy of QMS to the NBR ISO 9001 standard
Determinants of bank efficiency: the portuguese case
The objective of this study is to evaluate the technical efficiency of the Portuguese banking sector in the most recent period and to identify the determinants that explain it.
Methods: The methodology used consisted on the application of the non-parametric approach, Data Envelopment Analysis (DEA), to estimate the technical efficiency of the banks, in the period between the first semester of 2005 and the first semester of 2017. The analysis used the classic models CCR and BCC following the banking intermediation approach.
Findings & Value added: The results, in general, indicate that the level of efficiency of the Portuguese banking sector is high, suggesting that the banks operating in it are efficient in optimizing their resources. It also concludes that the determinants that influence efficiency are the size, the capital structure, the antiquity and the macroeconomic situation of the country.
To the best of our knowledge, this is the first approach to bank efficiency that involves time series data after the Portuguese sovereign debt crisis and, therefore, were not considered in previous studies.info:eu-repo/semantics/acceptedVersio

Latency and Lifetime Enhancements in Industrial Wireless Sensor Networks : A Q-Learning Approach for Graph Routing
Industrial wireless sensor networks usually have a centralized management approach, where a device known as network manager is responsible for the overall configuration, definition of routes, and allocation of communication resources. Graph routing is used to increase the reliability of communication through path redundancy. Some of the state-of-the-art graph-routing algorithms use weighted cost equations to define preferences on how the routes are constructed. The characteristics and requirements of these networks complicate to find a proper set of weight values to enhance network performance. Reinforcement learning can be useful to adjust these weights according to the current operating conditions of the network. In this article, we present the Q-learning reliable routing with a weighting agent approach, where an agent adjusts the weights of a state-of-the-art graph-routing algorithm. The states of the agent represent sets of weights, and the actions change the weights during network operation. Rewards are given to the agent when the average network latency decreases or the expected network lifetime increases. Simulations were conducted on a WirelessHART simulator considering industrial monitoring applications with random topologies. Results show, in most cases, a reduction of the average network latency while the expected network lifetime and the communication reliability are at least as good as what is obtained by the state-of-the-art graph-routing algorithms
Meta-analysis of femoropopliteal bypass grafts for lower extremity arterial insufficiency
BackgroundIn femoropopliteal bypass surgery, the use of saphenous vein grafts is preferable, but synthetic grafts are widely used above the knee. The objective of this meta-analysis was to assess the long-term patency of femoropopliteal bypass grafts classified as above-knee polytetrafluoroethylene, above-knee saphenous vein, or below-knee saphenous vein.MethodsStudies published from 1986 through 2004 were identified from electronic databases and reference lists; 73 articles contributed 1 or more series that used survival analysis, assessed femoropopliteal bypasses in one of the foregoing configurations, reported a 1-year graft patency rate, and included at least 30 bypasses. The series with a predominance of claudicant patients were included in meta-analysis C, and the series in which critical ischemia predominated were included in meta-analysis CI. Pooled survival curves of graft patency were constructed.ResultsIn meta-analysis C, the pooled primary graft patency was 57.4% for above-knee polytetrafluoroethylene, 77.2% for above-knee vein, and 64.8% for below-knee vein at 5 years; there was a significant difference between above-knee grafts at 3, 4, and 5 years (P < .05). The corresponding pooled secondary graft patency was 73.2%, 80.1%, and 79.7%, respectively (P > .05). In meta-analysis CI, the pooled primary graft patency was 48.3% for above-knee polytetrafluoroethylene, 69.4% for above-knee vein, and 68.9% for below-knee vein at 5 years; there was a significant difference between above-knee grafts until 4 years (P < .05). The corresponding pooled secondary graft patency was 54.0%, 71.9%, and 77.8%, respectively, with a significant difference between above-knee grafts at 2, 3, and 4 years (P < .05).ConclusionsThe great saphenous vein performs better than polytetrafluoroethylene in femoropopliteal bypass grafting and should be used whenever possible
A mortalidade materna devido a hipertensão arterial na cidade de São Paulo (1995-1999)
AIM: To describe the case profile of maternal death resulting from hypertensive disorders in pregnancy and to propose measures for its reduction. METHODS: The Committee on Maternal Mortality of São Paulo City has identified 609 cases of obstetric maternal death between 1995 and 1999 with an underreporting rate of 52.2% and a maternal mortality rate of 56.7/100,000 live births. Arterial hypertension was the main cause of maternal death, corresponding to 142 (23.3%) cases. RESULTS: Ninety-five (66.9%) of the deaths occurred during the puerperal period and 34 (23.9%) occurred during pregnancy. The time of death was not reported in 13 (9.2%) cases. Seizures were observed in 41 cases and magnesium sulfate was used in four of them. The causes of death were ruled to be cerebrovascular accident (44.4%), acute pulmonary edema (24.6%), and coagulopathies (14.1%). Cesarean section was performed in 85 (59.9%) cases and vaginal delivery in 15 (16.0%). CONCLUSION: Complications of arterial hypertension are responsible for the high rates of pregnancy-related maternal death in São Paulo City. Quality prenatal care and appropriate monitoring of the hypertensive pregnant patient during and after delivery are important measures for better control of this condition and are essential to reduce disorders in pregnancy.OBJETIVO: Descrever o perfil dos casos de morte materna decorrente de complicações da hipertensão arterial e propor medidas para sua redução. MÉTODOS: De 1995 a 1999 o Comitê de Mortalidade Materna da Cidade de São Paulo identificou 609 casos de morte materna obstétrica, com uma subnotificação de 52,2% e um CMM=56,7/100.000 Nascidos Vivos. A hipertensão arterial foi a principal causa de óbito materno, correspondendo a 142 (23,3%) casos. RESULTADOS: Ocorreram 95 (66,9%) de óbitos no puerpério e 34 (23,9%) durante a gestação. Em 13 (9,2%) casos não se teve referência ao momento do óbito. Houve relato de crises convulsivas em 41 casos com a utilização de sulfato de magnésio em quatro deles. As principais causas determinantes do óbito foram: o acidente vascular cerebral (44,4%), o edema agudo de pulmão (24,6%) e as coagulopatias (14,1%). A cesárea foi realizada em 85 (59,9%) casos e o parto vaginal em 15 (16,0%). Em 28 (19,7%) casos não foi realizada nenhuma conduta para interromper a gravidez e em 14 (9,8%) não se obteve relato do procedimento. CONCLUSÃO: As complicações da hipertensão arterial no ciclo gravídico-puerperal determinam altos índices de mortalidade materna na cidade de São Paulo. A realização de um pré-natal de qualidade e o atendimento apropriado da gestante hipertensa no parto e no pós-parto são medidas de fundamental importância para um melhor controle desse evento, sendo primordial para a redução dessas ocorrências
Reasons and benefits associated with ISO 9001 - Certification for sugar and ethanol companies
With increasing business competitiveness, companies have sought to adapt their processes and / or products to worldwide established quality standards in order to achieve a greater share of consumers having as favorable aspect the quality assurance of the products and/or services provided. It was observed that companies of different sizes have different challenges regarding the certification however, the degree of difficulty is the same for all of them. The objective of this paper is to verify the reasons for the implementation of ISO 9001, the obstacles encountered during the implementation, the benefits arising from the use of the quality management system and the degree of difficulty to implement this standard. This work was developed based on a survey involving companies certified with ISO 9001:2008 from the productive sector of sugar, ethanol and derivatives of sugarcane, located in all Brazilian states. It was observed that companies of different sizes have different challenges regarding the certification however the degree of difficulty is the same for all of them. Thus, we believe that expected results represent a very important contribution to examining the reasons, benefits and difficulties of the ISO 9001 to both, the companies and certification bodies, and to researchers.CAPES Foundation, (Process PE024/2008), the FAPEMIG Foundation (Processes: T EC-PPM-00520/13 and TEC-PPM-000 58-13) and the CNPq (Processes: 2 49160/2013-7, 310660/ 2012-2, 401082/2 014-8 and 478509/2012-
