To select 10 representatives for the ecotourism networks around the areas bordering national rivers in Korea, the spatial ranges for ecotourism have been established, the ecotourism potential analyzed, and the ecotourism resources information collected by the Regional Environmental Offices and the Korea National Park Service has undergone reviews, amendments, supplements, and verification processes through familiarization tour previews, and the following main results have been derived. First, the spatial ranges of the eco-tourism networks have been set as the watershed areas that include areas around the four major rivers and the rivers. Second, the areas with high potential value for ecotourism were selected through the analysis of ecotourism potential. Since EGIS was used for the analysis, it was inevitable that insufficient amount of localized information was reflected, and the use of the results as reference for the potential would be feasible. Third, it was possible, by reviewing, amending and complementing the results of ecological resource information collected by the Regional Environmental Offices and the Korea National Park Service, to select 50 representative ecological resources around the national rivers. The selected resources were considered for the adjacency, attractiveness of ecological resources, and uniqueness of the national rivers, and they were derived by screening expert advice, official opinion, and geographical analysis information. Fourth, 10 representative ecotourism networks based on watershed areas were selected, and suitable themes were given based on the resource characteristics. Fifth, the appropriateness for ecotourism has been confirmed, with the familiarization tour previews and survey results, preservation of the future ecotourism resources, and the establishment of the foundation as the basis. In the future, the remaining 9 ecotourism networks would also need to undergo a verification process such as familiarization tours. It is deemed that, through future ecotourism contests, if the programs that select locally-pioneered tourism programs resulting from the capacities of local entities and residents, then it would be more effective in discovering resources that are more localized and of higher regional value.

Thailand had set the National Water Management Strategy which covered main six areas in the next 12 years, i.e., by priority: (1) water for household, (2) water for agricultural and industrial production, (3) water for flood and drought management, (4) water for quality issue, (5) water from forest conservation and soil erosion protection, (6) water resources management. However due to the climate change impact, there is a question for all strategies is whether to complete this mission under future climate change. If the impact affects our target, we have to clarify how to mitigate or to adapt with it. Vulnerability assessment was conducted under the framework of ADB's (with the parameters of exposure, sensitivity and adaptive capacity) and the assessments were classified into groups due to their different characteristic and the framework of the National Water Management Strategy, i.e., water supply (rural and urban), water for development (agriculture and others), water disasters (floods (flash, overflow), drought, water quality). The assessments identified the parameters concerned and weight factors used for each groups via expert group discussions and by using GIS mapping technology, the vulnerability maps were produced. The maps were verified with present water situation data (floods, drought, water quality). From the analysis result of this water resources management strategy, we found that 30% of all projects face the big impacts, 40% with low impact, and 30% for no impact. It is clear that water-related agencies have to carefully take care approximately 70% of future projects to meet water resources management strategy. It is recommended that additional issues should be addressed to mitigate the impact from climate risk on water resource management of the country, i.e., water resources management under new risk based on development scenarios, relationship with area-based problems, priority definition by viewpoints of risk, vulnerability (impact and occurrence probability in past and future), water management system in emergency case and water reserve system, use of information, knowledge and technology in management, network cooperation and exchange of experiences, knowledge, technique for sustainable development with mitigation and adaptation, education and communication systems in risk, new impact, and emergency-reserve system. These issues will be described and discussed.

The objective of this study is to evaluate hydrologic impacts of climate change according to downscaling methods using the Soil and Water Assessment Tool (SWAT) model at watershed scale. We used the APCC Integrated Modeling Solution (AIMS) for assessing various General Circulation Models (GCMs) and downscaling methods. AIMS provides three downscaling methods: 1) BCSA (Bias-Correction & Stochastic Analogue), 2) Simple Quantile Mapping (SQM), 3) SDQDM (Spatial Disaggregation and Quantile Delta Mapping). To assess future hydrologic responses of climate change, we adopted three GCMs: CESM1-BGC for flood, MIROC-ESM for drought, and HadGEM2-AO for Korea Meteorological Administration (KMA) national standard scenario. Combined nine climate change scenarios were assessed by Expert Team on Climate Change Detection and Indices (ETCCDI). SWAT model was established at the Mankyung watershed and the applicability assessment was completed by performing calibration and validation from 2008 to 2017. Historical reproducibility results from BCSA, SQM, SDQDM of three GCMs show different patterns on annual precipitation, maximum temperature, and four selected ETCCDI. BCSA and SQM showed high historical reproducibility compared with the observed data, however SDQDM was underestimated, possibly due to the uncertainty of future climate data. Future hydrologic responses presented greater variability in SQM and relatively less variability in BCSA and SDQDM. This study implies that reasonable selection of GCMs and downscaling methods considering research objective is important and necessary to minimize uncertainty of climate change scenarios.

Objectives: Maternal morbidity and mortality are important healthcare issues. However there have been few studies on cost of illness (COI) from maternal disorders. This study aimed to estimate the COI due to maternal disorders in Korea. Methods: By reviewing previous studies and consulting expert we determined the scope of maternal disorders. We operationally defined maternal disorders as maternal hemorrhage, maternal sepsis, hypertensive disorders of pregnancy, obstructed labor, and abortion for maternal disorders. The reference period of this study is the year 2015. Main source of data were the National Health Insurance Service claims data, cause of death statistics from the Korea National Statistical Office, and the Korea Health Panel study. We classified the total costs into direct and indirect costs. The direct costs cover healthcare costs and non-healthcare costs. The indirect costs consist of productivity losses due to morbidity and premature death. Results: The cost of maternal disorders in 2015 was 229.7 billion won. The direct and indirect costs of maternal disorders were 165.2 billion won and 64.5 billion won respectively. The largest cost item for maternal disorders was healthcare cost (138.3 billion won, 60.2%). By age groups, the COI in 30-39 years old women were the highest (165.1 billion won, 71.9%). Abortion was the disorder with the highest COI among maternal disorders (71.9 billion won, 31.3%). Conclusion: The COI due to maternal disorders in Korea is quite substantial. Economic burden of maternal disorder increased when being compared with the year 2012 data despite the continued low birth rate in Korea. Therefore, it is necessary to continuously monitor the social costs of the maternal disorders in Korea.
