우리나라 하구에 조성된 담수호의 수자원은 다양한 용수 목적에 맞게 활용하고 있으며, 수질 기준에 부합하는 용수를 공급하고 담수호 및 간척지의 친환경적 가치를 높이기 위해서는 담수호의 상류 유역 및 유입 오염물질, 그리고 담수호 수체 특성에 대한 종합적인 이해를 기반으로 수질 오염 관리 대책을 수립하는 것이 중요하다. 일반적으로 담수호 개선을 위한 방안의 선정 방식은 연평균 수질 농도를 기준으로 목표하고자 하는 수질 기준의 만족 여부에 대한 평가와 경제적 평가를 함께 고려하여 최적의사결정 기반으로 주로 이루어져 왔다. 그러나 기존의 평가 방법에서는 목표 수질의 만족 여부가 중요하다는 점에서 담수호 수자원의 시기별 활용성에 대한 고려를 간과하기 쉽다. 또한 담수호 수자원 시스템의 수질 악화에 대한 회복탄력성을 높이는 일은 단순히 유역관리대책의 적용에 따른 수질 개선 문제와는 별도로 담수호 수자원 시스템의 지속 가능성과 연관된다는 점에서 기존의 평가 방식을 보완하기 위한 수단이 필요하다고 할 수 있다. 따라서 본 연구에서는 담수호 수자원 관리 방안을 평가하는 데 있어서 회복탄력성의 개념을 활용하였으며, 각 방안에 대한 시간적 변화에 따른 담수호의 회복탄력성 특징을 고려하기 위하여 동적 회복탄력성 개념 및 평가 방법을 도입하였다. 본 연구에서는 우선 기존의 수질 평가 방법에 따라 간월호를 대상으로 수질 개선 방안별 수질 변화를 SWAT-EFDC 연계모형을 통해 모의하고, 연평균 수질 농도와 총인 삭감량에 대해 분석하였다. 분석 결과, 간월호의 지형학적 특성에 따라 간월호 상류 구간의 수질 농도가 다른 구간에 비해 높게 나타났으며, 상류 구역의 경우 준설 시나리오만으로는 목표 수질을 달성하기 어려운 것으로 나타났다. 따라서, 상류 구역의 수질 목표 달성을 위해서는 준설 시나리오만으로는 한계가 있으므로 상류 유역 출구부에 위치한 하수처리시설의 총인 배출부하량을 삭감과 추가적인 유역 수질 관리 대책이 필요하다.

This study is to investigate the problem of credit rating by Korea Trade Insurance Corporation(KSURE) which evaluates overseas buyers in a state of capital impairment as G-grade regardless of the cause of capital impairment. This study classifies capital impairment into two types: deficit-type capital impairment due to accumulated operating losses and surplus-type capital impairment due to shareholder return policies such as dividends and treasury stock buybacks. It is proposed to improve the credit evaluation method on companies with surplus capital impairment from a formal review to a substantive review. This study is expected to improve credit rating of KSURE on overseas buyers for better support of trade credit insurance for exporters.

The government introduced the comprehensive evaluation bidding system with the goal of pursuing the best value and the global standard in 2016. However, for the evaluation criteria on the construction evaluation reflected to the comprehensive evaluation bidding system, the problems of the objectivity insufficiency, the inclusion of multiple subjective evaluation items, and the irrationality of the weight for each evaluation item are continue to be presented. The central office group, the local government, the relevant industry, and the expert group share recognition, but the solution is not derived. Hence, the major evaluation items to be improved were derived with the characteristics analyzed to secure the objectivity of the construction evaluation. For the analysis method, the standard deviation and the Fleiss Kappa analysis method were used by utilizing the characteristics that the construction evaluation criteria consist of all 4-point measures (good, average, insufficient, and poor). According to the result, the 10 evaluation items of the total 25 construction evaluation items were derived as the evaluation items to be improved. It was found in the analysis on the major characteristics of the derived evaluation items that the qualitative evaluation criteria such as 'Very Suitable' and 'Suitable' were commonly included in the detailed evaluation guidelines. Hence, as far as the future construction evaluation standards are concerned, the qualitative evaluation standards are sublated, and the improvement should be made mainly for the quantitative evaluation criteria enabling the objectivity assurance.

It's been almost 6 years since PIA was implemented based on legislation. So I analyzed problems of PIA from the perspective of ITSM 3 elements. I mainly took account of quality improvement of the report when I assessed systems processing personal informations. So, I propose in terms of logical validity improvement of assessment report. The improvements on 4 different outputs for each phase are many cases that I assessed systems processing personal informations. And I propose improvements on qualified assessors having capability of GRC and on process for managing the assessment system. To settle down PIA system as the reasonable and effective assessment system even after 2016, the statutory deadline for completion of PIA, assessors and appointed assessment firms and authorities should cooperate to complete the assessment system.

The purpose of this study is to improve the previous groundwater contamination vulnerability assessment method, apply it to the study area, and select priority areas for groundwater management based on the quantitative analysis of groundwater contamination vulnerability. For this purpose, first, the previous 'potential contamination' based on groundwater contamination vulnerability assessment method was upgraded to the methodology considering 'adaptation capacity' which reduced contamination. Second, the weight of groundwater contamination vulnerability assessment factors was calculated based on the analytical hierarchy process(AHP) and the result of survey targeting groundwater experts. Third, Gyeonggi-do was selected as the study area and the improved methodology and weight were implemented with GIS and actual groundwater contamination vulnerability assessment was carried out. Fourth, the priority area for groundwater contamination management was selected based on the quantitative groundwater contamination vulnerability assessment diagram. The improved detailed groundwater contamination vulnerability assessment factors in this study were a total of 15 factors, and 15 factors were analyzed as new and improved weight with higher 'adaptation capacity' than the assessment factor corresponding to the previous 'potential contamination' in the weight calculation result using AHP. Also, the result of groundwater contamination vulnerability assessment in Gyeonggi Province using GIS showed that Goyang and Gwangmyeong which were adjacent to Seoul had a high groundwater contamination vulnerability and Pocheon and Yangpyeong County had a relatively low groundwater contamination vulnerability. In this study, the previous groundwater contamination vulnerability assessment was improved and applied to study areas actually. The result of this study can be utilized both directly and indirectly for the groundwater management master plan at national and local government level in the future.
