Authentic assessment in software engineering education based on PBL principles: a case study in the telecom market

Abstract: The continuous growth of the use of Information and Communication Technology in different sectors of the market calls out for software professionals with the qualifications needed to solve complex and diverse problems. Innovative teaching methodologies, such as the "Software Internship" model and PBL teaching approaches that are learner-centered and focus on bringing market reality to the learning environment, have been developed and implemented with a view to meeting this demand. However, the effectiveness of these methods cannot always be satisfactorily proved. Prompted by this, this paper proposes a model for assessing students based on real market practices while preserving the authenticity of the learning environment. To evaluate this model, a case study on skills training for software specialists for the Telecom market is discussed, and presents important results that show the applicability of the proposed model for teaching Software Engineering.

Supervised, but Not Home-Based, Isometric Training Improves Brachial and Central Blood Pressure in Medicated Hypertensive Patients: A Randomized Controlled Trial

Abstract: Background: The purpose of this study was to compare the effects of supervised and home-based isometric handgrip training on cardiovascular parameters in hypertensives. Methods: In this randomized controlled trial, 72 hypertensive individuals (58±2 years old, 70% female) were randomly assigned to three groups: home-based, supervised isometric handgrip training or control group. Home-based and supervised isometric handgrip training was completed thrice weekly (4x2 minute at 30% of maximal voluntary contraction, with 1-minute rest between bouts alternating the hands). Before and after 12 weeks after the isometric handgrip intervention office, central and ambulatory blood pressures (BP), arterial stiffness, heart rate variability, vascular function, oxidative stress and inflammation markers were obtained. Results: No significant (p>0.05) effect was observed for ambulatory BP, arterial stiffness, heart rate variability, vascular function and oxidative stress and inflammation marker in all three groups. Office BP decreased in the supervised group (Systolic: 132±4vs.120±3mmHg; Diastolic: 71±2vs.66±2mmHg, p0.05) add control data here. Supervised handgrip exercise also reduced central BP systolic (120±5vs.109±5 mmHg), diastolic (73±2vs.67±2 mmHg); and mean BP (93±3vs.84±3 mmHg), whereas no significant effect was found in the home-based (Systolic:119±4vs.115±3; Diastolic: 74±3vs.71±3) and control groups (p>0.05). Conclusion: Supervised, but not home-based, isometric training lowered office and central BP in hypertensives.

Prevalence of pulmonary hypertension in patients with schistosomal liver fibrosis

Abstract: Between the April and July of 2007, patients undergoing treatment for schistosomal liver fibrosis, at a university hospital in north-eastern Brazil, were examined by transthoracic Doppler echocardiography (TTE). The main aim was to determine the prevalence of pulmonary hypertension in the patients. The thorax of each patient who had such hypertension, as indicated by an estimated pulmonary arterial systolic pressure (PASP) in excess of 35 mmHg, was then investigated by contrast-enhanced multidetector-row computed tomography (MDCT). The 84 patients (53 women and 31 men) enrolled in the study had a mean (S.D.) age of 50.06 (12.25) years. Nine (10.7%, with a 95% confidence interval of 5.0%-19.4%) of the patients were found to have pulmonary hypertension, with PASP ranging from 40-126 mmHg, and a median (S.D.) PASP of 58.78 (28.01) mmHg. The contrast-enhanced thoracic MDCT indicated that most of the patients with pulmonary hypertension had a pulmonary artery trunk that was unusually wide (67%) and more than 1.1-fold wider than the ascending aorta (56%), dilatation of the main pulmonary arteries (100%), a segmental artery that, in diameter, was more than 1.1-fold larger than the adjacent bronchi (89%), tapering of the peripheral pulmonary arteries (78%), and cardiac enlargement (78%). No patient suffered pulmonary embolism as a result of the investigations. The prevalence of pulmonary hypertension in the patients with schistosomal liver fibrosis (10.7%) justifies the screening of such patients by TTE.

Assistência Integral a Saúde do Homem: necessidades, obstáculos e estratégias de enfrentamento

Abstract: Objetivo: Conhecer as necessidades de saude, identificar os obstaculos que impedem o atendimento das necessidades de saude do homem e apresentar as estrategias de enfrentamento para uma assistencia integral e humana a um grupo de homens. Metodos: Estudo de cunho descritivo e exploratorio, com abordagem qualitativa. A coleta dos dados foi realizada em fevereiro de 2012 por meio de entrevista semiestruturada e analisadas a luz do referencial teorico. Resultados: A populacao masculina tem necessidades de saude a serem atendidas e referenciam como obstaculos, a vergonha de se expor, a impaciencia, a inexistencia de tempo e a falta de resolutividade das necessidades de saude. A humanizacao em saude predominou como estrategia de enfrentamento, atraves do acesso, do acolhimento, da comunicacao e do vinculo. Conclusao: A criacao da Politica de Atencao Integral a Saude do Homem nao foi suficiente para inseri-lo no contexto de saude, desta forma, propoe-se mudancas no modelo assistencial.
