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)
BACKGROUND Professional cleaning has emerged as a new industry in Taiwan in the past few years. However, information about the workload and prevalence of musculoskeletal disorders (MSDs) among these workers is still limited. This study investigated the prevalence of musculoskeletal discomforts and the characteristics of musculoskeletal activities of(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)
