Technology development has reshaped not only the business environment but also financial service. The purpose of this study is to investigate the factors affecting customer’s attitude and usage of Internet banking. Based on prior studies, this study identifies usefulness, ease of use, innovativeness, social influence, quality, cost as affecting factors of customer’s attitude and usage of Internet banking. This study intends to do a comparison analysis the relationship between customer’s attitude and usage of Internet banking by classifying Internet banking service into inquiry, transfer, and other service. Result shows that usefulness, quality, and cost are significantly related to the customer’s attitude toward Internet banking service, but ease of use, innovativeness, and social influence are not. Even though customer’s attitude was found to be significantly related to the use of Internet banking, the degree of it was different by service types inquiry, transfer, and other service in a row. It implicates that usage of Internet banking still centered on inquiry service.

도시유역에서의 관망의 배열은 통상 매우 복잡하기 때문에 있는 그대로를 모의하기에는 많은 번거로움이 수반되며, 있는 그대로를 모의한다고 하더라도 작은 오차들이 누적되어 좋은 결과를 기대하기 어려운 경우가 많다. 또한 합리적인 모형으로 실무에 많이 사용되는 모형일지라도 유역의 있는 그대로를 모의하기에는 부적절한 경우가 있기 마련이다. 이 같은 경우에 유역의 관망배열은 유출 수문곡선을 모의하기 위하여 그 모형에 적합하도록 단순화시키는 것이 보통이다. 그러나 이 같이 관망을 단순화시킬 경우라도 좋은 결과를 이끌어 내기 위하여는 유역내의 수리.수문학적인 특성을 빠짐없이 고려하여 단순화시켜야 한다. 본 연구는 이런 관점을 고려하여 단순화시킨 모의결과를 비교분석하고, 수리학적으로 어떻게 단순화시키는 것이 합리적인가를 살펴보고자 한다. Simplified sewer networks have been used to simulate runoff hydrographs for urban watersheds since configurations of sewer networks in urban area are commonly so complex that it is too cumbersome to simulate them as what they are. If they were to be simulated without any simplification, it is not likely that satisfactory results are obtained due to accumulation of numerous little errors. Even for the well-known models widely used in everyday practicesit is not appropriate to simulate everything in the watershed as what they are. In resolving these problems, it is common practice to simplify network configurations so as to be fitted to the models for runoff hydrograph simulation. In case of netwrok simplication, hydraulic and hydrologic characteristics of the watersheds should be carefully taken into consideration to derive meaningful results. On the bases of these considerations, this study analyzes simulation outputs using simplified networks and compares them, as well as inestigates the methods to make hydraulically sound simplification of sewer networks.

SNS has been emerging as an educational tool, because of its features such as discussion on course topics, feedback from peers and group collaboration. The purpose of this study is to investigate the affecting factors of learner's attitude and intention to use of SNS in college education. Based on prior studies self-efficacy, educational expectancy, subjective norm, habit and enjoyment were identified as affecting factors. According to the results of multiple regression analysis, all factors(self-efficacy, educational expectancy, subjective norm, habit and enjoyment) were found to be significantly related to the learner's attitude and intention to use. Result shows that educational expectancy and enjoyment are much more significantly related to the learner's attitude and intention to use of SNS in college education. It can provide a guideline of effective strategy for SNS utilization in college education.
