As the tourists of ecotourism are increasing, the supply for detailed information on tourist attraction is also significantly increasing. As a result of survey given to tourists, it showed that they are more interested in natural ecological resources rather than history or culture among resources of ecotourism and pointed out that more information on the region needs to be supplemented. In order to provide accurate, detailed and standardized information to tourists, ecotourism resources were categorized as experience type from the position of consumer and ecological resource type. And the category of experience is again divided into 4 types - nature, education, communication and adventure. Moreover, after developing the web-based homepage for it, the research proposed the cases of Tae-an area and Ulleungdo Island. If the problems from test operation are supplemented, it is expected to suggest the standard of mobile based digital storytelling technology in the field of ecotourism.

Integration system of conservation ecology, ecosystem management and land planing in landscape scale is major principle strategy for national management system of environmental resource and biodiversity. Current conservation strategy is concerned with not only population and habitat level but also ecosystem and landscape level. In especially, ecological networking to link core areas or major habitat patches is most eminent and emerging issue in European Union (EU) and North America. Moreover, the promotion of national ecological network system in EU is focused on national cooperation to construct ecological corridor for key habitat that distributed in many countries. Integrating landscape ecology into conservation ecology and restoration have important role to stimulate the network system in regional and national level. In this review paper, comprehensive and necessary considerations arisen from the view of landscape ecology were discussed for the present situations of wildlife conservation and management in Korea compared with other countries. Especially, the conservation strategy and policy of biodiversity were addressed in broad sense including habitat protection, legal approaches, and ecological network programs. Finally, a national ecological network system was suggested for environmental policy in Korea in global consideration after the Korean Unification.

하천의 최종 유출부와 해양이 만나는 지점을 하구라고 하며, 우리나라는 주로 서해안 지역에 하구 방조제 건설에 따른 담수호가 조성되어 다양한 목적으로 수자원이 활용되고 있다. 이러한 하구 담수호는 바다로 유입되기 직전의 물을 저류시켜 수자원 확보에 긍정적이나, 일반적으로 유역의 최하류에 위치해 있어 오염물질 유입, 부영양화, 염분 침출로 인한 오염물질 용출 등에 취약하다. 따라서 담수호의 회복탄력성 향상과 지속가능한 수자원 관리를 위해서는 미래 기후변화에 따른 영향 분석이 필수적이다. 특히 기후변화는 거대규모의 홍수과 같은 자연재난, 농업가뭄 및 식생가뭄 등의 증가로 이어질 수 있으므로, 이에 효과적으로 대비하기 위해서는 미래 기후조건에 따른 하천의 미래 유출량 변화 예측이 수행되어야 한다. 본 연구에서는 불확실한 미래 수문변화를 예측하기 위해 CMIP6(Coupled Model Intercomparison Project Phase 6) GCMs(Global Climate Models)의 SSP(Shared Socioeconomic Pathways) 시나리오를 유역 유출모델에 적용하여 기후변화에 따른 미래 유출특성의 변화를 예측하였다. 충청남도 서산시에 위치한 간월호 유역을 대상유역으로 선정하고, HSPF(Hydrological Simulation Program-FORTRAN) 모형을 적용하여 상류유역의 과거 및 미래 장기유출량 모의를 수행하였다. 모의된 시나리오별 유출량을 기반으로 최빈유량곡선법을 적용하여 미래의 기준유량 발생시점 및 지속기간의 변화를 분석하였으며, CVDs(Center-of-volume dates)의 변화를 통해 기후변화에 따른 홍수기의 시기적 변화 양상을 파악하고자 하였다. 본 연구의 결과는 미래 유역 환경변화를 고려한 담수호의 수자원 보전관리계획 수립에 있어 기초자료로 활용될 수 있을 것으로 기대된다.

The river ecosystems are influenced by numerous human activities such as agriculture and industrial operations, and benthic macroinvertebrates are utilized as important biological indicators. In this study, we aimed to assess the impact of land use surrounding rivers on river ecosystems in two industrial areas and two agricultural areas in Pyeongtaek city. We measured water temperature, dissolved oxygen (DO), and pH for physicochemical water quality assessment, and conducted water environment evaluation using benthic macroinvertebrates, cluster analysis, BMI, and ESB. Through water environment assessment, the environmental condition of rivers in agricultural areas was found to be more favorable compared to those in industrial areas. Consequently, it was observed that the impact on river ecosystems varied depending on the differences in anthropogenic activities.

In this paper, we focus the changing role of universities of University-Industry Collaboration (UIC) for enriching the regional business ecosystem network. For this research, we analyze 'Regional Innovation System(RIS)' - a specific UIC program- which provides a marketing service for firms, especially, SMEs with a specific problem by a group of consultants including CEOs, professors, and heads of regional public or private service providers. Then we have analyzed using network analysis how the business network was changed from RIS. Moreover, we will interview the participants in the important position of the network and investigate the reason for bringing a change in the network structure by using this program. This study illustrates that various types of network are formed between university and SMEs. Furthermore, the networks surrounding SMEs are extended to the other people connected to them. This means that the business network of SMEs had been diversified via the facilitation of university. This study throws new highlights on the new role for the university as a network promoter in addition to the partner as a technology-provider in the regional business ecosystem. Moreover, the network analysis between before-and-after can be used for the evaluation of the effectiveness of the various UIC programs.

하천의 수질개선을 위해서는 유역에서 배출되는 배출량을 제어하는 것뿐만 아니라 오염원별 기여도를 파악하고 효과적인 수질개선대책을 수립하는 것이 필요하다. 또한, 계절 및 유량조건에 따라 오염원의 배출량, 배출특성이 상이하게 나타나기 때문에 이를 고려하여 기여도를 파악하는 것이 필요하다. 본 연구에서는 청미천 유역을 대상으로 계절 및 유량조건에 따라 오염원별 기여율를 산정하고, 해당 유역의 수질개선을 위한 주요 인자를 도출하고자 한다. 기여율 분석을 위해 청미천 내에 유량 및 수질측정지점을 기준으로 소유역 구분을 하였으며, 소유역별로 물환경정보시스템을 통해 받은 유량 및 수질 자료를 활용하여 유량-부하량 관계곡선을 도출하였다. 유황조건별 부하량을 도출하기 위해 실측 유량 및 수질자료를 활용하여 유황곡선과 LDC(Load Duration Curve) 곡선을 작성하였다. 오염원별 기여도 산정을 위해 환경부의 2015년 전국오염원조사자료를 활용하여 소유역별 배출부하량을 산정하였으며, 앞서 산정한 LDC 곡선과의 비교를 통해 오염원별로 기여율을 산정하였다. 본 연구의 방법은 향후 유역의 수질개선대책 수립 시 오염원별 기여도 도출을 위한 기초자료로 활용될 수 있을 것으로 사료된다.

The purpose of this study is to estimate the ecological effect of DMZ for development and conservation of this area. Because of the political reason, field research and estimation of the ecological effect using field data is very difficult. Then we carried out the estimation of the ecological effect using Landsat ETM+ and ancillary data of digital maps. Because of military disturbance and agricultural activity of common people, NDVI of DMZ was very low value except the interior area of DMZ. According to the distance of DMZ, the variance of NDVI didn't show the logistic curve. This result has the reason as follows. The developing force at level plane of west and middle area reached to DMZ and we could concluded in that case of east area had been effect of regular cutting for view.
