This study aims to identify the methods of implementation for the 'National Research Foundation of Korea Open Access 2021(Plan)'. This study covers the methods of implementation in the three following core items: 1) developing the details on the amount, method, and procedures of APC support; 2) proposing methods for facilitating the transition of domestic Korean academic journals to open access journals; and 3) developing methods of entrusting papers to open access repositories. APC support should be guaranteed at a reasonable level. The average or median of APC values for the previous three years will be applied to set the upper limit for support each year. APC support will be provided when the paper is published to open access journals or transitioning journals to open access. Hybrid journals or dual access journals are not included. Support for open access publishing of academic journals in Korea during the transition period will be available for open access journals that have registered for CCL in KJCI or journals that have submitted their application for transitioning to open access. Publishing in hybrid, dual access or subscription-based journals must be accompanied by items related to copyright such as embargo. Research results will be used for the detailed implementation plan of 'NRF OA2021 (Plan)'. They will serve as the base data for the rapid, stable, and sustainable implementation of open access policy in NRF, addressing the Korean domestic academic journal publishing environment and the field of international academic communication.

This study performs the potential flood hazard analysis by applying elevation data, soil data and land use data. The susceptibility maps linked to elevation, soil and land use are combined to develop the new types of flood hazard map such as runoff production map and runoff accumulation map. For the development of the runoff production map, land use, soil thickness, permeability, soil erosion and slope data are used as runoff indices. For the runoff accumulation map, elevation, knick point and lowland analysis data are used. To derive an integrated type of flood potential hazard, a TOPSIS (The Technique for Order of Preference by Similarity to Ideal Solution) technique, which is widely applied in MCDM (Multi-Criteria Decision Making) process, is adopted. The indices applied to the runoff production and accumulation maps are considered as criteria, and the cells of analysis area are considered as alternatives for TOPSIS technique. The model is applied to Gamcheon watershed to evaluate the flood potential hazards. Validation with large scale data shows the good agreements between historical data and runoff accumulation data. The analysis procedure presented in this study will contribute to make preliminary flood hazard map for the public information and for finding flood mitigation measures in the watershed.

농업 비점오염원으로부터의 수질 보전이나 수자원 관리는 유역단위로 하는 것이 세계적 추세이며, 지형이 복잡한 우리나라에서는 더욱 효율적일 수 있다. 유역은 물이나 기타 물질들이 모여 강이나 더 큰 수계로 흘러드는 지표수의 범위라 표현할 수 있으며 그 범위를 정함에 따라 매우 중요한 의미를 지니게 된다. 특히, 강우에 따른 수자원의 유입과 유출이 토양을 통해 발생함에도 불구하고 기존의 유역단위 구분이 토양의 특성을 전혀 반영하지 못하고 있는 우리의 현실은 효율적 관리를 위한 유역단위 구분의 큰 단점으로 작용해왔다. 따라서, 농업적 관리뿐만 아니라 수질관리 및 수자원 관리를 위해서도 유역단위 특히, 소유역을 토양특성이 포괄하는 체계적 단위로 분류할 필요성이 있다. 토양학에서는 동일한 모재에서 유래된 일련의 토양이 미세지형에 따라 연속적으로 분포된 것을 Soil Catena(토양연접군)라고 한다. 이 토양연접군을 위주로 토양을 분류하게 되면 수문이나 기상현상 등의 주요 매질인 토양을 그룹화할 수 있는 가능성을 얻게 되고 이런 그룹화는 유역을 수계 위주의 유역군이 아닌 동일특성이나 유사특성을 나타낼 수 있는 유역군으로 분류가 가능하도록 유도할 것이므로, 이런 분류는 토양을 포함하는 다양한 수문모형의 적용성을 확대해 합리적 수자원 관리에 도움이 될 것이며 수자원 환경에 영향을 미치는 오염물질 관리에 대한 유역단위 보편성을 확보하고 농업에서의 최적관리를 가능하게 할 것이다. 우리나라 유역 세분화는 토양조사가 되어 있는 지역에만 한정해 분류에 이용했다. 대유역은 15개로 구분하였으며(그림 1), 중유역은 117개 소유역은 1,108개를 분석에 사용했다. 유역의 만곡도(하천의 실제길이 하천의 직선장) 산림의 비율(표준유역내 임지토양의 면적 / 소유역의 면적), 평탄지의 비율(표준유역내 평탄지의 비율 / 소유역의 면적), 다른 소유역으로부터의 유입이 있는지의 여부 등을 기본자료로 하였다. 이렇게 구분된 소유역은 유형적으로 보면 유사한 지형 및 토양특성에 따라 그룹화하였다. 유역내 평탄지가 유역면적의 25% 이상을 차지하는 지역을 평야지로 구분하며, 유역내 평탄지가 25% 미만이고 경사지가 45% 이상인 중간지, 유역내 평탄지가 25% 미만이고, 경사지가 45% 미만인 곳을 산간지로 구분하였다. 경사지는 산악지와 구릉지를 제외하여 모든 소유역을 모암 유래토양특성에 따라 16유형, 농업지대에 따라 3개의 유형으로 나눌 수 있으며 총 개의 유형으로 분류하였다. 이런 분류의 토대위에 향후 필요분야마다 구분이 가능한 기후특성을 포함시킨다면 최종적으로는 모든 것이 해설될 수 있는 유역군으로 만들 수 있을 것이다. 즉, 토양특징, 농업특징, 기후특징에 비점오염가능성 등 토지이용상 문제점등을 포괄한다면 다양한 자연현상을 기술할 수 있는 효과적인 유역군이 될 것이다.

Since the introduction of New Towns in Seoul MSA, land price has steadilly been risen due to the financial burden of constructing metropolitan transportation facilities. Despite metropolitan transportation facilities are utilized by New Towns as well as its surrounding area, the current situation is that most of the burdens, which is supposed to be shared with local governments, fall to developers. This study, with the case of Dongtan New Town, is to deduce rational structure of cost-sharing by the analysis of travel demands of metropolitan transportation facilities. Also, for the financing of the cost, the application methods of TIF(Tax Incremental Financing) have been suggested. The results showed that the proportion of travel which origins from New Town was 35.1%, which results in 800 billion won for the share of local government. For financing this amount of the cost, at least 20 years of financial period and the rate of 2% increase of real estate are needed in operating the TIF.
