본 연구에서는 유류로 오염된 주유소 저장 창고 밑부분의 토양에서 경유 분해 균주를 순수분리한 후, 스크린 테스트를 거쳐 고효율의 경유분해균주 KDi19를 선별하였다. KDi19균주는 16S rDNA 분석, 지방산 분석, 생리 생화학적 특징 그리고 형태학적 특징을 확인한 결과 Pseudomonas sp.로 동정되었다. KDi19는 온도 $30^{\circ}C$, pH 7, 그리고 균농도 1.0 g/L의 조건에서 48시간 동안 초기 1,000 mg/L의 경유 중 956.3 mg/L(95.6%)를 제거하였다. 또한 균농도 1.0 g/L, pH 7의 조건에서, 낮은 온도($20^{\circ}C$, $15^{\circ}C$, $10^{\circ}C$) 적용 시, 경유 1,000 mg/L을 48시간 동안 각각 63.9%, 18.5%, 17.0% 제거하였다. 마지막으로 균 농도 1.0 g/L, pH 7, 온도 $30^{\circ}C$ 조건일 경우, KDi19는 저농도 경유 50 mg/L와 100 mg/L를 24시간 동안 각각 49.0 mg/L(97.9%)와 96.2 mg/L(96.2%)를 제거하였다.

Kullback Discrimination Information (KDI) is one of the pattern recognition methods. KDI defined as a measure of the mutual dissimilarity computed between two time series was studied for detection and classification of bearing flaking on outer-race and inner-races. To model the damages, the bearings in normal condition, outer-race flaking condition and inner-races flaking condition were provided. The vibration sensor was attached by the bearing housing. This produced the total 25 pieces of data each condition, and we chose the standard data and measure of distance between standard and tested data. It is difficult to detect the flaking because similar pulses come out when balls pass the defection point. The detection and classification method for inner and outer races are defected by KDI and nearest neighbor classification rule is proposed and its high performance is also shown.

본 사례연구는 KDI국제정책대학원이 체계적인 기록물의 관리를 위하여 적용했던 기록관리학의 원칙 및 방법론, 그리고 이를 실제로 적용해 나가는 과정을 기술하는 데 그 목적을 두고 있다. 이 사례연구는 그 이전의 사례연구들과 달리 모형개발부터 시스템 구축까지 전 과정을 다루었다는 점에서 포괄적이라 할 수 있다. KDI대학원에서는 오랜 기간 동안 특별한 체계 없이 방치되어 왔던 기록물과 아카이브즈를 통합적으로 관리할 수 있는 포괄적인 개념의 기록관을 구축하였다. KDI대학원에서 기록관리의 도입은 행정정보화 및 지식정보화를 지원하고 대학원의 성과와 역사적 면모를 유지 전승할 수 있는 지침을 마련하는 토대가 되었다. 아울러 이번 사례연구는 타 대학 또는 기관에서 기록관리 체계 구축사업을 할 때 유용한 가이드가 될 수 있을 것으로 기대한다.

This study presents a real-time impact evaluation of a human capacity-building health project in Laos, financed by a Korean aid agency and executed jointly by Laotian and Korean higher educational agencies. The project aims to improve the health status of Laotians by enhancing practicing doctors' clinical performance capacity, to be attained by advancing academic achievement at the University of Health Sciences (UHS) in Laos. Therefore, this real-time impact evaluation adopted the difference-in-differences regression analysis method, showing that the project improved the academic achievement of the UHS students who were taught by the project fellowship awardees more, compared to the UHS students who were taught by non-fellowship faculty members. It remains to be evaluated whether these UHS students taught by the project fellowship recipients would also perform better clinically in public hospitals in the future.

This paper aims to identify the most effective mode of development finance flows for the economic growth of middle-income developing and least developed countries, separately. It also attempts to confirm whether governance has any significant role in the causal relationship between development finance flows and economic growth. Policymakers in each developing country should select the most effective modality of development finance inflows among the different modalities (such as Official Development Assistance (ODA) grants, Official Development Assistance (ODA) loans, FDI, and international personal remittances) and expand it for their economic growth. Dynamic panel regression models were used on 48 least developed countries and 89 middle-income developing countries, respectively, during the Millennium Development Era: 2000-2015. The empirical analysis results show that ODA grants and remittances were most effective in promoting economic growth for least developed countries, while FDI was most effective for middle-income developing countries. These findings were not affected by the status of governance of the individual country.

We investigate how reforestation contributed to stabilization of riverine water levels in South Korea. For the purpose, we estimate an equation capturing dynamic relationships among rainfall, upstream-area tree stock, and downstream water levels in three river systems of Hongcheon, Mangyeong, and Hyeongsan, using daily observations of precipitation and water levels for the period from 1985 to 2005. Simulation based on estimation results shows that increase in the tree stock in a river basin leads to a significantly suppressed peaking in riverine water levels in response to an abrupt and concentrated rain in the upstream area. For instance, an hour-long concentration of 100mm rain results in 0.7m rise in water level if the volume of growing stock is 1 million m³, whereas the rise in water level stays below 0.27m with 5 million m³ in the growing-stock volume.
