A ubiquitous English vocabulary learning system: evidence of active/passive attitudes vs. usefulness/ease-of-use
Yueh-Min Huang

1. Introduction
English is one of the most important languages. Many studies have indicated that vocabulary is the foundation of language learning (Sun et al., 2011; Wilkins, 1972). Previous studies have revealed the insufficiency of the provision of a systematic process by which to learn vocabulary. In this study, we developed a ubiquitous English vocabulary learning (UEVL) system to help …

Toona sinensis Leaf Aqueous Extract Improves the Functions of Spermand Testes via Regulating Testicular Proteins in Rats under Oxidative Stress
Sue-Joan Chang

Toona sinensis leaf (TSL) is commonly used as a vegetable and in spice in Asia. In this study, feeding with aqueous extract of TSL (TSL-A) alleviated oxidative stress and recovered the motility and functions of sperm in rats under oxidative stress. Protein expressions in testes identified by proteomic analysis and verified by Western blot demonstrated that TSL-A not
only downregulated the level …

Effects of Stroke Rehabilitation on Incidence of Poststroke Depression: A Population-Based Cohort Study
Chung-Yi Li

Poststroke depression may increase morbidity and mortality in stroke survivors. We conducted a cohort study to investigate whether receipt of rehabilitation intervention in 3 months of stroke onset may reduce the risk of post-stroke depression. The rehabilitation group included 1,285 stroke patients who received a rehabilitation regimen within the first 3 months of stroke admission in 2000-2005. …

Design of an Average-Current-Mode Non-Inverting Buck-Boost DC-DC Converter with Reduced Switching and Conduction Losses
Chia-Ling Wei

Due to the growth of consumer electronics market, there are more and more studies in energy saving to prolong service life of electronic products. Because the output voltage of batteries decreases with time (e.g., Li-ion: 2.7–4.2 V), it may be higher or lower than the required supply voltage (e.g., 3.3V). To use the entire battery output voltage range, a non-inverting buck-boost dc-dc converter …
