This study carried out to establish a master plan about healing forest in Gangwon-do focusing on healing road and visitor center. The site of this study was approximately 721 ha of mountain in Imgye-myeon, Gangwon-do, and the master plan was established through analysis of humanities-social and natural environments. The healing forest was developed 6 healing trails(10.5 km), devided by 3 steps, and each healing trail was designed to make rest area, wooden bridge, and open space. Also, visitor center, the core place of healing forest, was devided to several spaces as health measurement room, AV room, etc. and was planed for audio-visual education room for visitors.

This paper assessed environmental impacts of marine sand mining on coastal areas and Exclusive Economic Zones (EEZs) of Korea, and diagnosed problems of the related assessment statements for suggesting key assessment items (scoping) and system improvement. To mitigate conflicts and environmental impacts caused by large-scale, concentrated sand mining, we suggest it is critical to promote sustainable and eco-friendly utilization of marine resources while listening opinions from various stakeholders and analyzing alternative plans. Especially, it should be mandatory as a scoping item to provide verifiable data on the amount of sand, potential and accumulative impacts by mining, and key assessment items (e.g. erosion and sedimentation by submarine topography, benthic change, spreading of suspended solids, water pollution, grain-size change, and impact on fisheries resources). We also suggest that postassessment and monitoring should be improved to enable tracking of environmental impacts caused by sand mining through seasonal monitoring together with intermittent short-term surveys. In addition, effective measures to mitigate the impacts is also essential. As repeated sand mining at large-scale can damage marine ecosystems by long-term accumulated impacts, we suggest that assessment systems and regulatory policies should be developed and established, especially for ensuring reliability of assessment and review on selected major sandmining projects.

Mass production of forest medicinal plants is related to quality control of raw medicinal materials. Plant tissue culture is an important technology to produce high-quality plant materials. Numerous factors are reported to influence the success of in vitro regeneration of medicinal plants. Embryogenesis is known to be the most effective techniques and it has developed in some medicinal plant species. Various in vitro cultural condition for direct and/or indirect somatic embryogenesis systems have developed in Epimedium koreaum, Bupleurum falcatum, Paeonia lactiflora, Chrysanthemum zawadskii, Houttuynia cordata etc. In this study, we provide the present statue and information of in vitro propagation techniques that is able to apply as an efficient system for rootstock propagation system of forest medicinal plants.

최근 도시화 및 기후변화에 의한 홍수피해의 증가로 인하여 이에 대응하는 방안으로 저영향개발(LID) 요소기술에 관하여 다양하게 개발이 되고 있다. 하지만 이러한 요소기술에 대한 효율을 검증할 수 있는 표준화된 검증방법 및 기기는 부재한 실정이다. 본 연구에서는 LID 기법에 대한 물순환의 효율성 검증이 가능한 강우-유출 모의장치를 개발하였다. 소유역 내 강우가 균등하게 분사될 수 있도록 강우공간분포실험 및 유입유량-유효우량 관계 실험을 통하여 강우를 검증하고 유입되는 강우와 이로 인해 발생되는 침투 및 지표유출 관계 실험을 실시하였다. 그 결과 노즐의 종류에 따른 적정유량범위와 RPM의 관계를 정리하였으며 강우-유출 모의장치를 이용한 실험을 통해 투수면과 불투수면에서의 강우 시의 수문학적 물순환(지표유출, 중간유출, 침투량)의 관계를 정량적으로 검증하였다.

천연자원 및 물질순환은 자원채광, 운반, 처리, 활용, 회수 및 폐기 등과 관련된 모든 인간의 활동을 포함한다. 지속가능한 물질 관리는 물질순환을 통해 경제적 매개체에 맞추어진 통합된 정책수단이며 경제적으로 효율적이고 환경적으로 효과적인 물질의 사용을 위한 것이다. 산업광물, 금속광물 및 화석연료의 물질흐름은 회수, 처리, 소비 및 최종 폐기와 관련된 환경적 압력 때문에 지금껏 환경정책의 주된 영역이었다. OECD의 물질흐름분석연구는 회원국의 경제운용에서 물질자원의 중요성에 대한 이해의 폭을 넓혀 국가별국가간 천연자원 및 물질흐름에 대한 정량적이고 분석적인 지식기반을 증진하는 것이다. 현재 EU에서는 물질흐름계정이 몇몇 회원국에서 공식통계로 활용되고 있다. 주로 물질흐름분석은 물질흐름계정으로부터 정보를 활용하여 물질사용의 효율성을 평가하는 가치화기법으로서 기존의 경제모니터링시스템에서 파악되지 않는 천연자원 등의 폐기를 인지하는데 활용된다. 물질흐름분석에서 자원사용과 효율성은 장기간의 지속가능성 및 환경정책을 위한 중요한 주제로 떠오르고 있는 것이다.

The prediction of discharge is very important in water resources management and plan. In this study, we have analyzed discharge data of site at up and down stream in watershed. In order to forecast discharge the regression equations were developed by measuring flow data. Also, to forecast the change of water quality followed by change of inflow the correlation relationship between inflow of the Youngchun site and the Chunhju dam was shown as very high. The forecast of inflow at the Chungju dam would be possible through flow analysis of the Youngchun site. And, it is possible to forecast water quality by flow analysis because the correlation relationship of SS and turbidity followed by change of flow for each station of investigation was very high.

본 연구에서는 도시하천 유역의 신뢰성 높은 수문해석을 위해 지역적 성향을 고려한 도달시간 및 저류상수 공식을 개발하였다. 이를 위해 국내 대표 도시하천 유역인 중랑천, 탄천, 안양천, 홍제천 내 13개 유역을 대상으로 지역적 성향이 없는 유역특성인자와 지역적 성향이 있는 도시 및 강우특성인자를 분석하였으며, 단계적 다중회귀분석을 통하여 공식을 개발하였다. 개발된 공식은 국내외 경험식들과 함께 도시하천 유역에 대해 정확도를 비교 평가하였다. 분석결과 본 연구에서 개발한 공식의 계산값이 다른 경험식들에 비해 더욱 정확하게 모의하였으며 오차합, 평균오차, 평균제곱근오차 또한 가장 낮은 것으로 나타났다. 본 연구는 도시하천 유역이라는 지역적 성향을 고려하여 공식을 개발함으로써 기존 국내외 경험식들보다 더 나은 결과를 제시하였다는 측면에서 가치가 있다고 판단된다.

In this study, an evaluation system that can be used to evaluate the feasibility of developing and supplying hydrothermal energy for the operation of large-scale complex facilities was developed. To this end, this study derived factors to be considered when selecting a location for the use of hydrothermal energy using raw water from multi-purpose dams and regional water supply systems through literature survey and expert interviews. The evaluation indicators derived from this study are divided into four sectors: hydrothermal energy utilization factors, location factors, planning factors, and disaster safety factors, and are composed of 10 mid-level indicators and 34 detailed planning indicators. The relative importance of all factors was derived using the Analytic Hierarchy Process (AHP) technique, and the developed evaluation indicators and relative importance were applied to four multi-purpose dam regions in the country. As a result, it was found that in the development and use of hydrothermal energy utilizing regional raw water supply line the urban planning conditions of the supply site can have a greater impact on the location selection results than the hydrothermal energy development itself. Due to the characteristics of the evaluation indicators developed in this study and their nature as comprehensive indicators, it is believed that the results should be applied to determine the overall adequacy of site selection in the early stages of hydrothermal energy development. In the future, it is believed that it will be necessary to analyze the problems in supplying and operating hydrothermal energy using raw water from multi-purpose dams and regional water resources. Based on the analysis the evaluation system developed in this study is expected to be improved and supplemented.

The purpose of this study is to overcome the realistic pressure and the limit of school environmental education and to develop an environmental education program that can provide students, who live in an urban area, have difficulty in contacting with nature, with an opportunity to experience the nature in the school outdoor environment, which is their daily living space and is a ground of environmental education. First, I developed an analytical tool which can be used to determine the degree how the environmental education is related to the school outdoor environment with 8 categories(spaces). And I analyzed the 2007-79 curriculum of lower grade(1 and 2 grades) of the elementary school provided by the Ministry of Education and Human Resources Development by using the analytical tool and found out that this curriculum was suitable for the environmental education utilizing the school outdoor environment. According to this curriculum analysis, the studying subjects which could be suitable for the environmental education utilizing the school outdoor environment were extracted, and based on these subjects, an environmental education program was developed. The environmental education 'in' environment program were composed with 5 modules and 18 activity subjects suitable for students advancement phase, and these activities can be implemented with experiencing, understanding and expressing by using 5 senses. I also proposed a plan that can be used to apply this program continuously to the lower grades(1 and 2 grades) original experience activity class.
