RESUMO
The sunflower is an oilseed species, rustic, cultivated in different agroecosystems. The responses of cultivars to nitrogen fertilization vary according to the cultivar and environment. Therefore, this research aimed to evaluate the response of biometric characters of sunflower cv. Embrapa 122-V2000 under N doses. The experiment was carried out in a randomized block design with five treatments (0, 40, 80, 120 and 160 kg N ha-1) and four blocks. All characters were influenced (p<0.05) by N doses, fitting to the quadratic model. The maximum values of plant height (1.68 m), stem diameter (22.71 mm), leaf area (423.41 cm2), capitulum diameter (15.22 cm), dry biomass yield (6,075.13 kg DM ha-1) and grains (2,982.89 kg ha-1), N use efficiency from biomass (80.3 kg kg-1) and grains (43.27 kg kg-1) close to 90 kg N ha-1, this dose being recommended for the edaphoclimatic conditions of the Agreste Meridional Region of Pernambuco, Brazil.(AU)

Todos os caracteres foram influenciados (p<0,05) pelas doses de N, ajustando-se ao modelo quadrático. Os valores máximos de altura da planta (1,68 m), diâmetro do colmo (22,71 mm), área foliar (423,41 cm2), diâmetro do capítulo (15,22 cm), produtividade de biomassa seca (6.075,13 kg MS ha-1) e de grãos (2.982,89 kg ha-1), eficiência do uso do N da biomassa (80,3 kg kg-1) e dos grãos (43,27 kg kg-1) próximo aos 90 kg N ha-1, sendo esta dose recomendada para as condições edafoclimáticas da região Agreste Meridional de Pernambuco, Brasil.(AU)

RESUMO
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.

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 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 por cento: 1,87-10,29), com idade > 35 anos (OR = 3,06; IC95 por cento: 1,59-5,92), < 4 anos de estudo (OR = 4,95; IC95 por cento: 2,43-10,08), que tiveram parto cesáreo (OR = 3,06; IC95 por cento: 1,77-5,29) e para aquelas que não realizaram pré-natal ou tiveram menos de 4 consultas (OR = 9,78; IC95 por cento: 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.
