Resumo: O setor varejista de supermercados é de grande importância na geração de empregos e captação de mudanças no comportamento dos consumidores. Mudanças tecnológicas e mercadológicas ocorridas recentemente no setor aumentam a necessidade do aprimoramento de técnicas para a mensuração do desempenho individual das redes e a construção de parâmetros de comparação relativa entre as unidades. O objetivo deste artigo é analisar a eficiência de uma amostra de 31 supermercados de pequeno porte da região oeste de Santa Catarina. O método utilizado para a avaliação da eficiência foi a análise envoltória de dados (DEA), com as variáveis: faturamento, número de funcionários, área de vendas e o número de checkout’s, nos anos de 2014 e 2015. Os resultados encontrados apontaram para um baixo percentual de unidades em máxima eficiência de escala e técnica para os dois períodos analisados. Outra ponto relevante é a identificação das variáveis que apresentaram desajustes para o alcance da eficiência máxima das unidades (área de vendas e número de funcionários), sugerindo a existência de capacidade ociosa de estrutura.

Abstract: The retail supermarket sector is one of the most important in the third sector. Besides being one of that most generates direct and indirect jobs, it is one of the first to capture changes in consumer behavior. Given the strong competition and constant evolution of the sector, it is necessary to improve techniques for individual performance measurement of the networks and the construction of parameters of relative comparison between the units. The aim of this article is to analyze the efficiency of a 31 supermarkets sample in Santa Catarina, using Data Envelopment Analysis (DEA). The variables used in the investigation were gross sales, the number of employees, sales area and number of checkout's in the period of 2014 and 2015. The results pointed out a low percentage of units at maximum efficiency for the two periods analyzed. Another relevant finding was that the variables that presented a mismatch to reach the maximum efficiency of the units was the “Sales area (m2)” and “number of employees“, suggesting the existence of idle structure capacity.

Abstract Objective: To assess the reproducibility of two clinical criteria for the evaluation of restorations in primary teeth and the impact on treatment decision. Material and Methods: A cross-sectional study was performed selecting 71 resin-based composite restorations placed in primary molars of children who had sought dental treatment at a dental school. Two trained examiners evaluated independently the restorations using modified FDI and USPHS criteria. All restorations were assessed separately with each system in random order to avoid memory bias. Kappa statistics were used to determine inter-examiner reliability considering each parameter of both criteria and score final about treatment decision. McNemar test was used to compare the treatment decision with two criteria. The significance level was set at 5%. Results: Kappa values ranged from 0.28 to 0.93 with USPHS and 0.28 to 0.88 with FDI, considering each parameter separately. Inter-examiner agreement for treatment decision was excellent for both criteria (Kappa: 0.85-0.90). For clinical decision-making, no difference between criteria was found, irrespective of examiner. Conclusion: Low inter-examiner agreement for evaluation of each parameter of USPHS and FDI criteria does not reflect on reproducibility for treatment decision. Both criteria may be suitable for evaluation of composite restorations in primary teeth.
