  • Window interface to Hydrological Simulation Program-FORTRAN (WinHSPF) developed by the United States Environmental Protection Agency (EPA) was applied to the upstream of Nam-Han river watershed to examine its applicability for loading estimates in watershed scale and to evaluate non-point source control scenarios using BMPRAC in WinHSPF. The WinHSPF model was calibrated and verified for water flow using Ministry of Construction and Transportation (MOCT, 3 stations, 2003~2005) and water qualities using Ministry of Environment (MOE, 5 station, 2000~2006). Water flow and water quality simulation results were also satisfactory over the total simulation period. But outliers were occurred in the time series data of TN and TP at some regions and periods. Therefore, it required more profit calibration process for more various parameters. As a result, all the study was performed within the expectation considering the complexity of the watershed, pollutant sources and land uses intermixed in the watershed. The estimated pollutant load for annual average about $BOD_5$, T-N and T-P respectively. Nonpoint source loading had a great portion of total pollutant loading, about 86.5~95.2%. In WinHSPF, BMPRAC was applied to evaluate non-point source control scenarios (constructed wetland, wet detention ponds and infiltration basins). All the scenarios showed efficiency of non-point source removal. Overall, the HSPF model is adequate for simulating watersheds characteristics, and its application is recommended for watershed management and evaluation of best management practices.

  • The objective of our study is to examine the Earnings Quality of Win-Win Growth Corporate. The level of Win-Win Growth Corporate is measured by Win-Win Index of korea commission for corporate partnership. Earnings Quality is proxied by Accounting Conservatism that is measured by the method of Givoly and Hayn(2000). The samples of this study selected from listed corporate, consist of 3,608 observations can be collected from 2011 to 2017 at TS-2000. The result of this study can be summerized in the following. the Win-Win Growth has a significant positive relevance on Accounting Conservatism is the proxy of internal Earnings Quality. This means that Win-Win Growth corporate has a higher the Earnings Quality relatively. These results were supported by additional analysis that used the sample that is made up the Win-Win Growth Corporate completely. According to our study, we can expect that the Earnings Quality of Win-Win Growth corporate is true as steel. But this study have some limitation. Especially we can't explain the reason why the Win-Win Growth has a significant positive relevance on Earnings Quality. And, despite additional analysis, there are the limitation of controlling for endogeneity. We hope that our paper can help investor making a economic decision on investment and officials making a effective policy on the Win-Win Growth.

  • The Web is the largest distributed information space but, the individual's capacity to read and digest contents is essentially fixed. In these Web environments, mining traversal patterns is an important problem in Web mining with a host of application domains including system design and information services. Conventional traversal pattern mining systems use the inter-pages association in sessions with only a very restricted mechanism (based on vector or matrix) for generating frequent K-Pagesets. We extend a family of novel algorithms (termed WebPR - Web Page Recommend) for mining frequent traversal patterns and then pageset to recommend. We add a WebPR(A) algorithm into a family of WebPR algorithms, and propose a new winWebPR(T) algorithm introducing a window concept on WebPR(T). Including two extended algorithms, our experimentation with two real data sets, including LadyAsiana and KBS media server site, clearly validates that our method outperforms conventional methods.
