AIMS Pulse pressure/stroke volume (PP/SV) is regarded as a surrogate index of arterial stiffness (AS). Strain echocardiography is a novel method to evaluate systolic and diastolic left ventricular (LV) function. The aim of this study was to investigate the effect of AS on segmental relaxation and systolic deformation in hypertensive disease. METHODS AND RESULTS We evaluated 70 hypertensive pa...

Abstract Recent studies have shown how the variability of material properties affects nonlinear behaviour unreinforced masonry (URM) walls. To preserve historical built heritage, variations in structural capacity URM buildings associated to aging and deterioration should be quickly predicted, by integrating with health monitoring risk management. In this study, relationships between features ar...

Fatigue behavior of glulam moment resisting joint subjected to repeated cyclic loading has not been well clarified. In addition, the accuracy conventional design formulae for rotational stiffness and yield/ultimate should be discussed especially related method obtain material properties. this research, tests were conducted drift pined joints with insert-steel gusset plate tensile-bolted joint. ...

Aging is associated with decline in a multitude of cognitive processes and brain functions. However, a growing body of literature suggests that agerelated decline in cognition can sometimes be reduced through experience, cognitive training, and other interventions such as fitness training. Research on cognitive training and expertise has suggested that age-related cognitive sparing is often qui...

BACKGROUND Aging may cause various functional abilities gradually deteriorate. With changes in social forms, the trend of functional fitness decline will change accordingly. Therefore, this study endeavored to identify the trends in functional fitness decline by comparing the differences in the functional fitness of females in various age groups. METHODS Thirty six healthy females were divide...

Concrete in maritime structure is vulnerable to deterioration owing external sulphate attack, which can be exacerbated by wetting-drying action (WDA), jeopardizing its resistance cyclic loads such as wind, wave and earthquake actions. This study aims investigate the compressive fatigue behavior of concrete exposed attack WDA marine environment. Cyclic loading test was conducted on after 150 day...

this paper considers the fuzzy inventory model for deteriorating items for power demand under fully backlogged conditions. we define various factors which are affecting the inventory cost by using the shortage costs. an intention of this paper is to study the inventory modelling through fuzzy environment. inventory parameters, such as holding cost, shortage cost, purchasing cost and deteriorati...

Two studies examined the associations between life regrets and indicators of quality of life across the adult life span. Given that opportunities to undo regrets decline with age, regret intensity was expected to be inversely associated with subjective well-being and health among older adults. In addition, the research explored protective factors that have the potential to reduce older adults' ...

Abstract In this paper the relationship between the use of abortion and contraception among married women in a society experiencing uronid decline in fertility is analysed using data from the Korean National Fertility Survey of 1974. The level and pattern of abortion before and after modern contraceptives became widely available are described, and the implications of the changing patterns of ...
