A dislipidemia pode ser definida como um grupo de desordens no metabolismo de lipídios, caracterizado pela elevação dos níveis de colesterol e triglicerídeos. Pode ser classificada em primária ou secundária e é considerada um grande fator de risco para doenças cardiovasculares. O estudo teve como objetivo evidenciar a importância da alimentação na prevenção e controle da dislipidemia. Para tanto, foi realizada uma revisão narrativa de literatura, utilizando para o estudo, as bases de dados Periódicos Capes e livro do período entre 2002 e 2020. Na estratégia de busca os descritores aplicados foram: hiperlipidemia, lipídios, doenças cardiovasculares, dieta e estilo de vida, nos idiomas português e inglês. Verificou-se que, as mudanças nos hábitos alimentares (diminuição do consumo dos ácidos graxos saturados, aumento do consumo de ácidos graxos monoinsaturados ou poli-insaturados, redução da ingestão de colesterol e aumento da ingestão de fibras solúveis) devem ser a primeira medida não farmacológica utilizada como parte eficaz da mudança de estilo de vida para prevenção e controle da dislipidemia.

The further ultra-thin packaging structure has made packaging warpage a major technical problem, which restricts the improvement of packaging yield. In response to this issue, this article proposes a new finite element modeling and simulation method that considers the time and temperature dependence of composite materials, as well as the shrinkage behavior of the Epoxy Molding Compound (EMC) and the substrate during the assembly process. The model parameters are fitted and corrected using a step-by-step simulation approximation method combined with actual warping data. The correction parameters were applied to the warping prediction of a new packaging model, and the predicted data were in good agreement with the actual test data, verifying the correctness of the modeling method, which can be used for rapid screening of packaging structures and materials.

Abstract Hydraulic conductivity is an important geological and geotechnical characteristic, necessary for flow-related problems and underground construction. In many countries, databases for hydrology parameters and groundwater level (GWL) are well established, often not fully utilized for directly estimating hydraulic conductivity characteristics. In this study, a method for estimating hydraulic conductivity based on a regionally established database of hydrological, geological, and geotechnical parameters is proposed. For this purpose, 68 databases of hydrological, geological and geotechnical parameters in different regions in Korea were collected and adopted to develop a data-based estimation method of soil hydraulic conductivity. The time response of GWL to precipitation was considered as a key influence factor on the hydraulic conductivity of soil, as it directly affected the infiltration process of rainfalls into soil deposits. Moving average (MA) of precipitation was introduced, which gave the best correlation to GWL, to account for the effect of accumulated precedent precipitation. Case examples were selected and used to check the validity of the proposed method.
