ABSTRACT With the objective of identifying the concerns, attitudes, and opinions of meat buyers and their relationship with their choice of place of purchase (supermarkets, free fair, or butchers), 381 consumers in the city of Garanhuns, Brazil, were interviewed. Data analysis was performed using descriptive statistics and discriminant analysis, complemented by stepwise regression, Wilks’ Lambda test, and Fisher’s linear test. Most of the respondents expressed that inadequate commercialization of meat occurred in free fairs, and the lack of hygiene and the fact that meat was exposed in the environment without refrigeration were the main preoccupations. They also reported that meat consumption without inspection could lead to disease transmission, with pork being considered the most dangerous. Based on the theory of planned behavior, buyers agreed that their attitudes toward the purchase of meat (concern with food safety, price, animal welfare, environment, and slave labor) influenced their purchasing decisions. Regarding the subjective norms, the results indicated that purchase intention could be modulated by the opinion and judgment that other people exercise on the buyer’s choice decision. Regarding perceived control, the respondents said that they were confused at the time of purchase and got irritated after making a purchase that did not satisfy their desires. The factors that differentiated consumers who prefer to buy meat in supermarkets from those who prefer butchers and free fairs are mainly the price of the product, custom/tradition, customer service, and hygiene of the establishment. Buyers who have a lower level of schooling and live in rural areas also tended to buy meat in free fairs.

Este estudo de caso-controle analisou fatores de risco para mortalidade materna no Recife, Pernambuco, Brasil, no período de 2001-2005. Os casos foram 75 óbitos maternos obstétricos, identificados no Sistema de Informações sobre Mortalidade, investigados e analisados pelo Comitê de Mortalidade Materna. Os controles, selecionados no Sistema de Informações sobre Nascidos Vivos, pela amostra sistemática, foram 300 mulheres residentes no Recife cuja última gravidez ocorreu no mesmo período e não resultou em óbito. O risco de morte foi mais elevado para as usuárias do SUS (OR = 4,47; IC95%: 1,87-10,29), com idade > 35 anos (OR = 3,06; IC95%: 1,59-5,92), < 4 anos de estudo (OR = 4,95; IC95%: 2,43-10,08), que tiveram parto cesáreo (OR = 3,06; IC95%: 1,77-5,29) e para aquelas que não realizaram pré-natal ou tiveram menos de 4 consultas (OR = 9,78; IC95%: 5,52-17,34). Os resultados reafirmam as desigualdades sociais na determinação de mortalidade materna no Recife. Além disso, indicam a necessidade de aprimorar a assistência à saúde da gestante durante o pré-natal, parto e puerpério.

A case-control study was conducted to investigate risk factors for maternal mortality in Recife, Pernambuco State, Brazil, in 2001-2005. Cases were 75 maternal obstetric deaths in Recife, identified from the Mortality Information System, investigated and analyzed by an expert committee on maternal mortality. Controls, selected from the Information System on Live Births using systematic sampling, were 300 women living in Recife whose last pregnancy occurred during the same period and ended in live births. Increased risk of maternal death was associated with use of the public health system (OR = 4.47; 95%CI: 1.87-10.29), age > 35 years (OR = 3.06; 95%CI: 1.59-5.92), < 4 years of schooling (OR = 4.95; 95%CI: 2.43-10.08), cesarean section (OR = 3.06; 95%CI: 1.77-5.29), and lack of prenatal care or fewer than four prenatal visits (OR = 9.78; 95%CI: 5.52-17.34). The results confirm social inequalities in maternal mortality in Recife and indicate the need to improve healthcare for women during the prenatal period, delivery, and postpartum.

Este trabalho foi desenvolvido em um solo aluvial na Estação Experimental da Embrapa Algodão, município de Souza, Estado da Paraíba, Brasil, com o objetivo de estudar a variabilidade espacial da densidade do solo. A área tem uma superfície cultivada de 17 ha e os testes de campo foram feitos em 40 pontos amostrais, locados na linha central longitudinal de cada parcela agrícola, eqüidistante de 50 m. Na determinação da densidade do solo, foi utilizado o método do anel volumétrico, em amostras com estrutura indeformada para as profundidades de 0-30, 30-60 e 60-90 cm. A variabilidade espacial foi determinada pela técnica de estatística clássica e da geoestatística. Na análise estatística clássica, a densidade do solo para as três profundidades apresentou baixos valores de desvio-padrão e coeficiente de variação, indicando pouca variação da densidade do solo com aumento da profundidade. A densidade do solo manifestou estrutura de dependência espacial, modelada por meio de semivariogramas, os quais permitiram a interpolação por "Krigagem", apresentando estrutura esférica nas profundidades de 0-30 e 60-90 cm, com alcance de 46 m e estrutura exponencial com alcance de 255,10 m para a profundidade 30-60 cm.

This research was carried out aiming at studying soil density variability, in a soil alluvial Embrapa Algodão Experimental Station, Sousa, Paraíba, Brazil. The area has a cropped surface of 17 ha and field trials were done on 40 sampling points, placed on the central longitudinal line of each agricultural plot, distant 50 m. On the soil density determination the volumetric ring was used, in deformed structural samples for three depths: 0-30, 30-60, and 60-90 cm. Spatial variability was determined by classical statistics and geostatistics. In the classic statistical analysis of the soil density for the three depths presented standard deviation and variation coefficient low values, indicating low variation of the soil density with the increase of the depth. The of soil density manifested structure of spatial dependence, modeled through semivariograms, it was interpolated for "Kriging", the presenting spherical structure on 0-30 and 60-90 cm depth, reaching 46 m for both depths exponential structure reaching 255,10 m for 30-60 cm of depth.
