The results showed that the average concentration of O3 monitored by mobile monitoring was significantly higher than that at the national control point in the urban area of Chaozhou City. During the study period, the daily variation of O3 concentration was in the form of a single peak. In the afternoon>in the evening>in the morning, there was a maximum of 279 μ g/m3 of O3 concentration in the afternoon. In addition, O3 has obvious spatial distribution characteristics. High concentration O3 is mainly distributed in Dongshan Road, Woshi Road and other areas with large traffic flow, indicating that high concentration ozone may be related to the precursors of vehicle exhaust emissions.展开更多

Together, they have successfully carried out the establishment and maintenance of 13 fixed debris flow monitoring stations over the island and 2 mobile debris flow monitoring stations. During July 2004, a powerful southwest air current brought by Mindulle Typhoon caused serious flood in central and southern Taiwan. This paper aims to describe the establishment of debris flow monitoring systems in Taiwan and the observation of the debris flow event during Mindulle Typhoon at Aiyuzi River in Shenmu Village, Nantou County by the monitoring station.展开更多

It has become essential for some telecommunication companies to focus on customer satisfaction with industrial products used by the government and enterprise customers. Following the review of a previous study of customer satisfaction and with the help of experiential level theory,this article attempts to establish a Satisfaction Factors Model for researching customer satisfaction with industry applications. We chose a product named "Mobile Monitor" and investigated the emotional satisfaction of 127 users and company leaders from different walks of life,and showed that 7 of the product's features affected the customers' overall emotional satisfaction. Lastly,this paper points out management implications of this application based on quantitative results. It presents a preliminary exploration program for customer satisfaction research in this specific field. The empirical research on a specific product based on experimental level theory may serve as a reference for other companies that desire to carry out similar surveys in future.展开更多
