This study aims to find the awareness, problem, effectiveness judgment, solution of smart student card. The research method used a questionnaire and we performed in the Chungbuk National University total 15 college for 300 university students on May, 2014. The main results were as following; First, many students think that the document which issue proceedings need isn‘t a lot and student card issue needs long time from application to last issue. Second, In case of recognition of personal credit information consent, most of the respondents don t think importantly about personal credit information consent. Third, recognition level s result about personal information management is that senior is higher than junior. and the lower grade was remembering the memory about the collection information in comparison with the upper grades well. Fourth, There were lots of opinions that the awareness about the financial function of the smart student card will be good if the most of respondents was selectively possible.

In order to improve the fuel economy of a hydraulic drilling machine, which consumes relatively large amount of fuel compared to other typical construction machinery, a comparison is made between gravimetric fuel consumption using mass flowmeter and CAN signal. And, since the data of CAN signal is close enough to the measured data of a flowmeter, fuel consumption at real work mode is measured and analyzed using CAN signals. A result show that drilling mode occupies about 67.4% of total fuel consumption. It is concluded that this work may contribute to enhance fuel economy of hydraulic drilling machines.
