According to Capability Maturity Model Integration (CMMI), the purpose of Process and Product Quality Assurance (PPQA) is to provide staff and management with objective insights about processes and their associated work products. Such purpose is usually achieved through the implementation of software inspections. Although software inspection be a common practice, it is time-consuming and expensive, which turns the implementation in small and medium-sized teams infeasible. To improve the software inspection, this paper proposes a domain ontology for representing the concepts of quality assurance inspection, which is independent, extensive, shareable and semantically strong. Through the ontology it is possible to provide a formal structure to support the development of software engineering solutions with quality. To support the quality assurance inspections, we developed an agent-based prototype that encapsulates the ontology model. The prototype is able to generate inspection checklists and automatically allocate noncompliance issues. We validated the approach through a case study that shows an increase of inspection coverage and adherence of process. © 2015 IEEE.

The aim of the study was to assess the effect of eccentric training using a constant load with longer exposure time at the eccentric phase on knee extensor muscle strength and functional capacity of elderly subjects in comparison with a conventional resistance training program. Twenty-six healthy elderly women (age = 67 ± 6 years) were randomly assigned to an eccentric-focused training group (ETG; n = 13) or a conventional training group (CTG; n = 13). Subjects underwent 12 weeks of resistance training twice a week. For the ETG, concentric and eccentric phases were performed using 1.5 and 4.5 s, respectively, while for CTG, each phase lasted 1.5 s. Maximum dynamic strength was assessed by the one-repetition maximum (1RM) test in the leg press and knee extension exercises, and for functional capacity, subjects performed specific tests (6-m walk test, timed up-and-go test, stair-climbing test, and chair-rising test). Both groups improved knee extension 1RM (24–26 %; p = 0.021), timed up-and-go test (11–16 %; p < 0.001), 6-m walk test (9–12 %; p = 0.004), stair-climbing test (8–13 %; p = 0.007), and chair-rising test (15–16 %; p < 0.001), but there was no significant difference between groups. In conclusion, the strategy of increasing the exposure time at the eccentric phase of movement using the same training volume and intensity does not promote different adaptations in strength or functional capacity compared to conventional resistance training in elderly woman. © 2015, American Aging Association.

The present study compared the effects of 12 weeks of traditional resistance training and power training using rated perceived exertion (RPE) to determine training intensity on improvements in strength, muscle power, and ability to perform functional task in older women. Thirty healthy elderly women (60–75 years) were randomly assigned to traditional resistance training group (TRT; n = 15) or power training group (PT; n = 15). Participants trained twice a week for 12 weeks using six exercises. The training protocol was designed to ascertain that participants exercised at an RPE of 13–18 (on a 6–20 scale). Maximal dynamic strength, muscle power, and functional performance of lower limb muscles were assessed. Maximal dynamic strength muscle strength leg press (≈58 %) and knee extension (≈20 %) increased significantly (p < 0.001) and similarly in both groups after training. Muscle power also increased with training (≈27 %; p < 0.05), with no difference between groups. Both groups also improved their functional performance after training period (≈13 %; p < 0.001), with no difference between groups. The present study showed that TRT and PT using RPE scale to control intensity were significantly and similarly effective in improving maximal strength, muscle power, and functional performance of lower limbs in elderly women. © 2016, American Aging Association.

Despite the importance of peach (Prunus persica (L.) Batsch) in Rio Grande do Sul, little is known about mites fluctuation population considered important to this crop. The objective of this study was to know the population diversity and fluctuation of mite species associated with Premier and Eldorado varieties in Roca Sales and Venâncio Aires counties, Rio Grande do Sul. The study was conducted from July 2008 to June 2009 when 15 plants were randomly chosen in each area. The plants were divided in quadrants and from each one a branch was chosen from which three leaves were removed: one collected in the apical region, another in the medium and the other in the basal region, totalizing 180 leaves/area. Five of the most abundant associated plants were collected monthly in enough amounts for the screening under the stereoscopic microscope during an hour. A total of 1,124 mites were found belonging to 14 families and 28 species. Tetranychus ludeni Zacher, 1913, Panonychus ulmi (Koch, 1836) and Mononychellus planki (McGregor, 1950) were the most abundant phytophagous mites, whereas Typhlodromalus aripo Deleon, 1967 and Phytoseiulus macropilis (Banks, 1904) the most common predatory mites. The period of one hour under stereoscopic microscope was enough to get a representative sample. In both places evaluated the ecologic indices were low, but little higherin Premier (H' 0.56; EqJ: 0.43) when compared to Eldorado (H' 0.53; EqJ 0.40). In Premier constant species were not observed and accessory only Brevipalpus phoenicis (Geijskes, 1939), T. ludeni and T. aripo. Higher abundance was observed in December and January and bigger amount in April. Already in Eldorado, T. ludeni and P. ulmi were constants. Greater abundance was observed in November and December, whereas grater richness in December and January. In both orchards were not found mites in buds. Tetranychus ludeni is the most abundant phytophagous mites with outbreak population in November, December and January and high predator diversity was observed on associated plants and on peach plants, indicating the existence of species mobility in peach orchard.

Introduction: Metabolic syndrome (MS) is one of the main risk factors for cardiovascular diseases (CVD) and identifying its components in young adults may constitute an important prevention tool.Objective: Analyzing applicability of the Visceral Adiposity Index (VAI) for predicting components of MS in young adults.Methods: Cross-sectional survey with 444 individuals, mean age 25.6±6.5, 77.7% females. We obtained data on weight, height, waist circumference (WC), body fat percentage (BF%), fasting glycemia, triglycerides (TG), total cholesterol (TC), HDL cholesterol (HDL-c), LDL cholesterol (LDL-c), and blood pressure (BP), as well as information on their lifestyles. Body Mass Index (BMI), Waist-to-Height Ratio (WHR) and VAI were calculated. Adiposity measurements were compared to the MS components, and for VAI, we determined the predictive capacity of MS components occurrence and the area below the ROC curve.Results: VAI correlated to glucose (r=0.136), HDL-c (r=-436), and TG (r=0.825) in females, and amongst men, it correlated to glucose (r=0.258), HDL-c (r=-0.550), TG (r=0.897), and DBP (r=0.290). An increased VAI was associated to an increased risk of abdominal obesity (OR=1.86), hypertriglyceridemia (OR=30.74), and low HDL-c (OR=3.95). Among obesity indicators, VAI presented a larger area below the curve for increased TG and low HDL-c.Conclusion: VAI presented an association to MS components in males and females with an increased risk of abdominal obesity, hipertriglyceridemia, and low HDL-c, proving to be a good MS components predictor even among healthy young adults. © 2014, Grupo Aula Medica S.A.
