Objective: To analyze the frequency of Pap smear testing in young women with at least one pregnancy in Teresina, capital of the state of Piauí, Brazil. Methods: A cross-sectional study was undertaken from May to December 2008. A convenience sample of 464 young women was selected, and data were collected using a pre-tested questionnaire. Women giving birth in the first four months of 2006, in six hospitals in Teresina, were included. Inadequate Pap smear frequency was defined as an interval of more than 1 year between tests. Results: Mean age was 20 years. The frequency of Pap smear testing was every 6 months in 180 women (39.0%) and yearly in 160 (34.5%). Fifteen women (3.2%) had never had a Pap smear test. Simple logistic regression showed an increase of 48.0% in the risk of inadequate Pap smear frequency (P = 0.049) in women who did not use any contraceptive method at their first sexual intercourse, and 49.0% (P = 0.044) in those who were not able to choose between a male or female gynecologist when seeking health care services. On multivariate logistic regression, having more than one pregnancy increased the risk of inadequate Pap smear frequency by 71.4% in comparison to having only one pregnancy (P = 0.011). Conclusions: The fact that many young women had Pap smear testing at intervals shorter than 1 year does not improve cervical cancer screening and may burden the health care system. Multiparity was a risk factor for inadequate Pap smear frequency, an aspect that must be taken into account when providing gynecological care to young women. Source

Green corn is a crop of great economic value for small and medium farmers, especially in irrigated areas. The objective of the study was to assess the yielding of green ears and other features of six cultivars of corn, undergoing sowing density with irrigation. The experimental design in split plots, with six main treatments (cultivars), four secondary treatments (densities) and four replications arranged in randomized blocks was utilized. The Cativerde 2, P3232, BM3061 and AG4051 cultivars showed the greatest heights of plants, whereas SWB551 was the smallest one. The smallest average height of insertion of the first ear was obtained by SWB551. AG4051, AG1051, BM3061 and P3232 outsized and outnumbered the other ones in terms of commercial ears scattered. Among the four planting densities tested, 50,000 plants/ha provided the highest corn ear yielding. The P3232 hybrid features higher thermal cycle and accumulation in relation to other cultivars, with BM3061 being the most precocious. Source

The present paper shows a theoretical reflection on action research methodology as an alternative strategy to the conventional model of scientific investigation. Methodology is discussed from the perspective of two scholars who propose two different structural models: action-investigation cycle and flexible stage model. We provide examples of the use of action research from studies carried out by nurses. Action research is an emergent model which is being more and more adopted in educational and nursing fields, reflecting the necessity of deeper theoretical knowledge and revealing itself as a useful instrument in nursing research.

The intensive use of soils in the Cerrado biome has caused modifications in soil properties, as well as in the performance and quality of organic matter. The Cerrado of Piauí has been exploited without due concern for the preservation of natural resources, where production systems are characterized by intensive land use. The objective of this research was to evaluate the effect of the agricultural use in altering the biological properties and dynamics of organic matter of Yellow Oxisols cultivated with soybean. This research was carried out in the "Serra do Quilombo", located in the Cerrado region of Piauí state. To assess changes in soil properties, induced by agricultural use, soil samples were collected from sites with different use history involving conventional and no tillage systems; PC 7/PD 8 - seven years of conventional agriculture followed by eight years of no-tillage; PC5/PD4 - five years of conventional system followed by four years of no-tillage; PC3/PD3 - three years of conventional system and three years of no-tillage and CN - native cerrado vegetation. The evaluated soil properties were basal respiration, microbial biomass C, metabolic quotient, microbial quotient, total organic C and total N. Physical fractionation was used to evaluate organic matter dynamics. The results were subjected to variance analysis and showed that the soil management under conventional cultivation and subsequent implantation of notillage system affected soil biological properties in relation to the soil under native cerrado vegetation. The replacement of native cerrado by annual no-tillage crops reduces the levels of microbial biomass C and total N and elevates the basal respiration in treatments after three and four years of no tillage, indicating that these periods are insufficient to improve the above properties. The increase in the time of land use with no tillage decreases the level of particulate organic C and maintains the C-associated minerals in relation to the soil under native cerrado vegetation.

Software development is a challenging, but seldom amusing activity. At the same time, gamification, a recent trend that brings game mechanics to websites and interactive media, together with many past works that propose the use of serious games to teach software engineering in a fun way, show evidence that this type of real-world activity can also incorporate game design elements. In this work, we propose a novel approach: incorporating game mechanics directly into a software development process, effectively turning it into a live game. We show interesting results from a case study with a production team of a software house, and firmly believe it is important that the game academic community spreads this type of knowledge to influence other research areas. © 2011 IEEE.
