Since living environment has improved, waterfront space using and clear water demand have increased. Ministry of Environment (ME) designated polluted reservoir (worse than 4th grade) as a priority management reservoir to improve water quality (better than 3rd grade) accordingly. Minstry of Agriculture, Food and Rural Affairs (MAFRA) aims reservoir water quality 4th not 3rd grade. And water quality of agricultural reservoirs was not a great interest. For this reason, there are very few water quality monitoring data. However after designating as a priority management reservoir, reservoir manager should start water quality and flow monitoring of reservoirs and inflow streams. This process makes it possible setting complex model to accurate prediction of reservoir water quality and volume. Mulwang reservoir designated as a priority management reservoir in September 2014. In this study, BASINS/WinHSPF and EFDC-WASP were used to predict effect of water quality improvement countermeasures in Mulwang reservoir. To improve water quality of Mulwang reservoir, Siheung-si and Korea Rural Community Corporation (KRCC) established water quality improvement countermeasures. However result of simulation adapting these countermeasures cannot achieve 3rd grade. So 4 additional scenarios were adapted and the result satisfied 3rd grade. This study could help to establish water quality improvement countermeasure by using complex modeling.

The city of Siheung in the Kyunggi-do Province has various natural resources such as the ocean, mountains, wide farmland, various types of wetlands, streams and rivers. In addition, the city has a big greenbelt, which consists of two-thirds of the area, where development has been regulated. Since the city has a relatively well-preserved natural environment, it offers a great potential for regional development. The purpose of this study is to create an eco-tourism resource plan for the Mulwang reservoir, which offers many opportunities for ecotourism in the city of Siheung. This study includes a literature review for planning elements and suggests a comprehensive plan that includes conservation, eco-restoration, route program and practice program for ecotourism in and around the site. The plan also includes eco-farming, a visitor center, an ecovillage, the chance to experience livestock farming, opportunities to learn about and experience the forest, tracking, eco-learning, an environmental interpretation facility, fishing and aquatic-oriented leisure activities. This study's process and results show possibilities that can be applied to other areas where eco-tourism using natural resources is used for regional development.

남조류에 의한 수화가 발생한 과림, 도창, 물왕 저수지로부터 시료를 채수 하여 남조류 분해 균주의 분리를 시도하였다. BG-11배지에 Anabaena cylindrica를 double layer method를 이용하여 남조류 lawn을 만들어 각각의 시료를 $100\mu{l}$씩 smearing하였다. $28^\circ{C}$ 3,000 Lux light chamber에서 13일간 배양하여 도창 저수지 시료를 접종한 Anabaena cylindrica lawn에서 남조류 분해능을 가지는 곰팡이를 분리하였다. 분리된 곰팡이의 동정은 Vitek system을 이용하여 수행하였으며, 그 결과 Cryptococcous laurentii로 동정되었다. SDS-PAGE 결과 Cryptococcus laurentii는 4개(29, 35.2, 40.9, 51.1 kDa)의 세포외 분비 단백질을 가지는 것으로 확인되었으며. Anabaena cylindrica와 혼합 배양시에는 특히 29 kDa의 단백질이 많이 분비되는 것을 확인하였다.
