This Paper provides perceptual metrics for video quality based on properties of human visual system, and audio quality based on human audition. All metrics work without reference signals, allowing non-intrusive, in-service measurements. A simple and easy-to-learn user interface displays the metrics and saves them in popular file formats like CSV. In this paper, proposed method was able to various and corrective measurement for the multimedia service video quality. As that it was able to application to set up service guide line and the methode of measurement and system for the set up standardization of the high quality video service.

In O2O environment (Online-to-Offline), providers attract new customers via websites and lead them to pay online, then induce them again to offline when receiving products. Thus, online and offline channel is integrated and create synergy for marketing in O2O context. As online and offline channel coexist in O2O, consumers' perceptions for products and services that providers offer cannot help being different compared to an independent channel (i.e., either online or offline). Therefore, this research aims to explore the effect of perceived service quality on consumer's trust and attitude, who have purchased products in O2O context. For testing the hypothesized research model, the current paper conducts survey and empirical test.

This study was intended to conduct a prospective study on the P2P Car-sharing service, which will be established as a new business model in the future, by identifying consumers' intention to accept the technology for the P2P-based Car-sharing service that will be introduced and spread in earnest in the future. The main results are as follows. First, the quality characteristics of the P2P Car-sharing service all have a statistically significant positive(+) effect on the perceived usefulness and ease of use of users, and among the quality characteristics, the service characteristics have a relatively strong effect on the perceived usefulness and ease of use, respectively. Second, both perceived usefulness and ease of use had a statistically significant positive(+) effect on users' intention to use P2P Car-sharing service, and ease of use was more dependent on intention to use P2P Car-sharing service. Third, the ease of use of the P2P Car-sharing service had a strong positive(+) effect on their perceived usefulness. As a result of this study, the most important factor to consider in establishing a P2P-based Car-sharing platform is to be constructed in the form of a universal design that prioritizes user convenience rather than usefulness and various functions of the service. It was suggested that UX design should be made, considering the surrounding clues, which are service environment elements.
