Previous studies have presented conflicting claims regarding reasons that people become addicted to the Internet. In this study, we attempted to identify predictors of Internet addiction based on Sullivan's interpersonal theory and Internet addiction literature. In our research model, it is hypothesized that good parent-child relationship positively… (More)
Over the past few decades, the widespread phenomenon of Internet abuse has gained attention from the public, academia, and the media. In a departure from this negative viewpoint, however, researchers and educators have devoted considerable effort in attempting to understand the influence of online communication on people's psychological well-being. This… (More)
Hispolon is one of the most important functional compounds that forms Phellinus linteus (Berkeley & Curtis) Teng. Hispolon has antioxidant, anti-inflammatory, antiproliferative and anticancer effects. In this study, we analyzed the functions of hispolon on melanogenesis and apoptosis in B16-F10 melanoma cells. The results demonstrated that hispolon is… (More)
th percentile nodes of HyStream is 35 seconds shorter than that of CoolStreaming. Note that our approach has small overhead of 6% redundant packets due to FEC, compared to SplitStream and CoolStreaming. In addition, HyStream has no more than 0.5% extra control overhead compared to SplitStream and CoolStreaming, even in a high peer churn environment.
Recently, many related researches focus on using mathematical approaches or artificial techniques to efficiently improve software development process (SDP). This paper provides a managerial viewpoint to discuss software process improvement (SPI) and introduces an alternative orientation that can lead to asking new questions. We combine activity-based… (More)
The descending noradrenergic (NAergic) system is one of the important endogenous analgesia systems. It has been suggested that noxious stimuli could activate descending NAergic system; nevertheless, the underlying neuronal circuit remains unclear. As NAergic neurons in the A7 catecholamine cell group (A7) are a part of the descending NAergic system and the… (More)
