Distribution of microphytobenthic biomass in Martel Inlet, King George Island (Antarctica)

The spatial and temporal variation of microphytobenthic biomass in the nearshore zone of Martel Inlet (King George Island, Antarctica) was estimated at several sites and depths (10-60 m), during three summer periods (1996/1997, 1997/1998, 2004/2005). The mean values were inversely related to the bathymetric gradient: higher ones at 10-20 m depth (136.2 +/- A 112.5 mg Chl a m(-2), 261.7 +/- A 455.9 mg Phaeo m(-2)), intermediate at 20-30 m (55.6 +/- A 39.5 mg Chl a m(-2), 108.8 +/- A 73.0 mg Phaeo m(-2)) and lower ones at 40-60 m (22.7 +/- A 23.7 mg Chl a m(-2), 58.3 +/- A 38.9 mg Phaeo m(-2)). There was also a reduction in the Chl a/Phaeo ratio with depth, from 3.2 +/- A 3.2 (10-20 m) to 0.7 +/- A 1.0 (40-60 m), showing a higher contribution of senescent phytoplankton and/or macroalgae debris at the deeper sites and the limited light flux reaching the bottom. Horizontal differences found in the biomass throughout the inlet could not be clearly related to hydrodynamics or proximity to glaciers, but with sediment characteristics. An inter-summer variation was observed: the first summer presented the highest microphytobenthic biomass apparently related to more hydrodynamic conditions, which causes the deposition of allochthonous material.

Metodologia de construção de um painel de indicadores para o monitoramento e a avaliação da gestão do SUS

Este estudo teve como objetivo desenvolver uma metodologia de construção de um Painel de Monitoramento e Avaliação da Gestão do Sistema Único de Saúde (SUS). O processo participativo utilizado e a sistematização realizada permitiram identificar uma estratégia efetiva para a construção de instrumentos de gestão em parceria entre pesquisadores, instituições acadêmicas e gestores do SUS. A sistematização final do Painel selecionou indicadores da gestão do SUS em termos de Demandas, Insumos, Processos, Produtos e Resultados de forma a disponibilizar um instrumento simples, ágil e útil para a avaliação em qualquer instância de gestão e mais transparente e de mais fácil comunicação com todos os interessados na tomada de decisão. Tomar a gestão do SUS como objeto destes processos e práticas em seus aspectos normativos possibilitou o diálogo entre teorias sistêmicas e aquelas que consideram a centralidade do ator social no processo de tomada de decisão.

BIOLOGICAL ASPECTS OF THE SAILFIN DORY Zenopsis conchifer (LOWE, 1852) CAUGHT BY DEEP-SEA TRAWLING FISHERY OFF SOUTHERN BRAZIL

Biological aspects of sailfin dory, Zenopsis conchifer, were studied from 839 individuals obtained from deep-sea commercial bottom trawling off southern Brazil at depths up to 526 m in 2002 and 2003. Samples included fish from 101 mm Lt and 15 g up to 640 mm Lt and 2,9 g. The sex-ratio was 50% at 150 mm Lt and between 300-350 mm Lt, with females outnumbering males in the remaining size classes. Reproductive activity seems to peak between July and August ( austral winter). Size at attainment of 50% maturity (Lt(50)) was 311 mm Lt in females. The mean length and maturity of the specimens increased with depth, suggesting that larger fish concentrate in deeper waters.

Health education intervention in early and late postmenopausal Brazilian women

Aim To identify aspects of health in postmenopausal Brazilian women using a health-related educational program provided by a multidisciplinary team as part of the primary care approach for early and late postmenopausal symptoms. Design A prospective cohort was formed with 69 postmenopausal women; they were divided into groups corresponding to early (n = 32) and late postmenopause (n = 37) through gynecological and clinical evaluations. We administered the Kuppermann-Blatt Menopausal Index and the Women's Health Questionnaire before and after health education instructions. Results The average age for the onset of menopause was 47.9 years (n = 69). Fifty women (72.5%) in this study had completed their primary education, 78.3% (n = 54) performed manual labor, and 60.9% (n = 42) showed concomitant chronic illnesses. After attending a series of health-related presentations, the mean weight of the women was reduced by 3.54% in early postmenopausal women (p < 0.001) and by 2.06% in the late postmenopausal group (p < 0.001). The mean abdominal circumference was reduced by 1.75% (p < 0.001) in the early postmenopausal group. In addition, the total score in the Kuppermann-Blatt Menopausal Index decreased by 34.38% in the early and by 33.33% in the late postmenopausal groups. According to the Women's Health Questionnaire, there was a decrease in the domain Depressive mood by 0.839 to 0.700 (p < 0.001) in the early and by 0.814 to 0.648 (p < 0.001) in the late postmenopausal groups. Conclusion Regardless of improving menopausal symptoms and anthropometric parameters, the effects of the multidisciplinary team activities in early postmenopausal women may be similar to those in late postmenopausal women.

Effects of moisture content on structural and dielectric properties of cassava starch films

In this work, it was evaluated the effect of moisture content on the structural and dielectric properties of cassava starch films by means of Fourier Transform infrared spectroscopy (FTIR), impedancimetric, and gravimetric analysis. The film samples were equilibrated in hermetically sealed desiccators, containing different saturated salts in water in order to promote activity of water between 0.11 and 0.85. The position and amplitude of the peaks in the fingerprint region of the FTIR spectra were changed due to the modifications in the interactions between the polymeric chains and water molecules. These effects may be related to the formation of semi-crystalline regions in the film structure. The dielectric properties of the films were also strongly dependent on the moisture content, showing a non-linear and a linear region, which was attributed to the domain of bound and free water in the film, respectively. The gravimetric analyzes showed the typical sigmoidal behavior, attributed to the way the water interacts with the biopolymer. Finally, the flexibility of the films increased with water content increasing.

O gerente de projetos de TI em organizações com níveis de maturidade diferenciados

A literatura sobre gestão de projetos mostra, de forma recorrente, a importância da figura do gerente no desempenho dos projetos. O presente artigo apresenta os resultados de um levantamento (survey) do papel do gerente de projetos de TI como elemento condicionante do desempenho desses projetos. Os resultados encontrados mostram que a relação do gerente de projetos com o desempenho dos projetos é alterada pelo nível de maturidade da organização executante em gestão de projetos. Nas organizações com menor maturidade existe uma relação muito mais forte do perfil do gerente com o desempenho dos projetos.Isso sugere que as organizações que conseguem estimular sua maturidade em gestão de projetos criam condições para que o desempenho de seus projetos fique menos dependente da ação individual dos gerentes.
