Natural selection is the core idea of evolution that pre-service biology teachers need to understand to solve diverse biological problem. This study aims to investigate the level of Korean pre-service biology teachers' understanding of natural selection by comparing their knowledge with their Chinese, American, and German biology major undergraduate counterparts. In particular, this study focuses on two conceptual components of natural selection (i.e., ecology and genetics). This study used a total 1226 pre-service biology teachers and biology majors' data. The instrument measuring the understanding of natural selection concepts was Conceptual Inventory of Natural Selection, which consists of ten ecology concept items and ten genetics concept items. The Rasch model analysis, multivariate analysis of variance, and univariate analysis of variance were used for the statistical tests. The result reveals that the level of Korean pre-service biology teachers' understanding of natural selection were similar with Chinese undergraduates' understanding and significantly lower than American and German undergraduates.' In the first year student data, the level of genetics concept of Korean pre-service biology teachers were significantly lower than Chinese and German students. In the fourth year student data, the level of ecology concept of Korean pre-service biology teachers were significantly lower than American and German students. Based on these results, the ecology concept education and balanced natural selection concept education are discussed.

This thesis represents the integrated 3D DEM using both the process of satellite image and the real value of topographic maps. This DEM is draped on satellite image processed to improve representations of the real world. The 3D visualization and 3D animation with satellite imagery data enables to depict more vivid and realistic world. The paper also describes and implements the natural environmental/ecological information system that consists of 7 modules to manage environmental data systematically through an enhanced user interface. We make use of topographic map, satellite imagery data and several thematic maps. Each module has a user interface enabling to assist particular needs of decision-making for ecological/environmental assessments associated with spatial analysis of ecosystem and classification of the environmental status quo and other purposes.

We've compared and conceptually evaluated the newly emerging concept of nature-based solutions (NbS's), in the aspect of water management, and existing similar solutions of different naming, all of which are based on ecosystem functions. In this study, it is found that NbS's seem significant and meaningful both educationally and understandably in the aspect that it can comprehensively cover and include the existing methodologies and solutions using the functions of natural ecosystem to socio-environmental challenges. It, however, seems not quite different from the broad-meaning of green infra, including Eco-DRR, in terms of the approaching methodologies in water management. The conceptual and spatial hierarchy of each practice in water management considered in this study can be expressed in the narrowing order of NbS-(EE)-BGI-(CRT)-GI-LID. Last, the term LID, which is the best management practice for storm water management in the development project, can be replaced with the term GI for clarification and less confusion both in academia and practice.

설악산국립공원은 1965년에 천연보호구역, 1970년에 국립공원 제 5호, 1982년 유네스코에 의해 생물권보존지역으로 지정된 지역이다. 우리 나라 국립공원에서는 물론 다른 자연보존지역에서도 찾아볼 수 없는 중요성이 강조된 지역이나 연간 400만명의 이용객이 집중되기도 하는 지역이다. 우리 나라 국립공원은 본래 관광개발을 위해 지정된 동기를 갖고 있어 자연생태계 및 자연경관도 중요하지만 현실적으로는 합리적인 이용도 중요하다. 그러나 지금까지 국립공원은 자연보존에 대한 관리는 도외시 한 채 이용객 집중에 의해 발생되는 도로, 시설물, 건축물, 각종 오염에 대한 대책마련도 제대로 하지 못하여 국립공원하면 국민은 '등산이나 하고 값싼 음식점과 여인숙 수준의 숙박시설이 있는 관광지'정도로 인식하고 있다. 지난 30년간 압축고도성장을 해 온 우리 나라는 국토의 자연환경이 수없이 훼손되고 또한 옥외 레크레이션활동의 증가로 환경오염이 계속 증가되었다. 설악산국립공원도 예외는 아니어서 저앗ㅇ부와 등산로 주변생태계, 계곡생태계 등이 오염되어 식물, 포유동물, 물고기, 곤충 등에 영향이 나타나고 있지만 대피소, 휴게소, 숙박시설을 중심으로 한 오염행위는 계속 늘어만 가고 있다. 이제 설악산국립공원은 거의 위기상황에 도달된 느낌이다. 이런 시기에 환경생태학회 국립공원분과위원회 회원들은 `96년 외설악 지역, `97년 내설악지역을 2년 동안 각 분야에 걸쳐 조사를 수행하였다. 지난 12년간 외부의 지원도 없이 연구비를 자체 조달하여 힘들게 국립공원 연구를 진행하여 온 일환으로 설악산국립공원 조사를 2년 동안 수행한 것이다. 이번 조사는 `96년 가을 북한공비침투로 많은 지역에 대한 출입이 통제되어 외설악연구의 일부가 누락되었음을 첨언한다. 본 글에서는 2년 동안 본 회원들이 조사한 내용에 의해 설악산 국립공원의 현황을 분석하고 관리개선 방향을 제시하였다.

This study analyzed the characteristics of emergy inputs from environmental sources that are essential in maintaining ecological processes and providing ecosystems services of the tidal flat ecosystems in Korea. Environmental sources provided a total of $4.98{\times}10^{21}sej/yr$ of emergy to the tidal flats of Korea. The emergy inputs from environmental sources were worth 1,141 billion ￦/yr. This is the value of environmental conditions that are the basis of ecosystem services provided by the tidal flat ecosystems. The emergy input per hectare to regional tidal flats decreased along the coastline from northwest to southeast, with the highest input in the Incheon-Gyeonggi area in the central western part of the Korean coast and the lowest input in the Busan area in the southeastern end. This reflects the general distribution pattern of the magnitude of tidal ranges along the Korean coast. There was no a clear-cut relationship between emergy inputs per unit area and fishery production(expressed in emergy quantity) per unit area. However, tidal flats in the west coast with higher emery inputs per unit area produced more fishery products than those in the south coast with lower emergy inputs, suggesting a possibility that the emergy inputs could be used for the rapid evaluation and comparison of the potential for ecosystem service provision by individual tidal flats.

청계천 복원의 효과가 하천의 형상, 종 조성, 종 다양성 변화의 유연성 및 환경 개선 효과 측면에서 검토되었다. 복원된 청계천은 하천의 종단 및 횡단 형상에서 모두 낮은 자연성을 나타내었다. 종 조성은 부분적으로 자연하천과 유사한 조성을 보였으나 전반적으로 낮은 자연성을 보였다. 종 다양성은 비교적 낮았지만 복원의 역사를 고려할 때 양호한 것으로 평가되었다. 하류와 수변에서는 홍수 후 많은 변화를 가져와 자연으로 회귀할 가능성도 보였지만 상류와 홍수터 이상에서는 변화의 유연성이 낮아 자연으로 회귀하는데 많은 시간이 소요될 것으로 평가되었다. 인공위성 영상 분석 결과, 복원된 청계천은 기온 완화 효과를 나타내었다. 그 밖에 복원된 청계천은 그 주변의 분산된 녹지를 연결하여 그린네트워크를 구축하고자 할 때 핵심적 역할을 할 것으로 기대되어 경관생태적 측면에서의 환경개선효과도 기대되었다.

This study aims to define the meaning of 'Sangsaeng (mutual beneficence)' within the context of 'Sangsaeng ecological theory,' a form of discourse of that has emerged from Daesoon Jinrihoe's perspective on ecology. Sangsaeng ecological theory applies the concept of interdependence to ecology in order to explain how Sangsaeng, which is commonly used as an ethical system for humans, can be applied to the realm of ecology such that it extends its scope of application to include non-human beings. Interdependence, when applied to ecology, is formed via relationships between individuals. Such relationships can be positive, negative, or neutral, and the type of interdependence that emerges can be competitive, predatory, parasitc, and symbiotic. Even if the relationship between individuals ends negatively, it can still exert a positive effect on the ecosystem. Consequently, all of these produce a type of 'dependence'. However, relationships that end negatively can generate grievances, and from the perspective of Sangsaeng ethics, this type of interdependence is to be avoided. Therefore, by way of contrast, ecological Sangsaeng may include both relationships of positive interdependence and relationships of predation, parasitism, and competition in so far as there no grievances. Ecological theory requires a perspective that enables an understand of the relationship between nature and humans in an integrated way that does not separate them. One view of universe, known as Cheonji-saengin-yongin (Heaven and Earth give produce humans make use of them) provides insights into the relationship between the universe and humans and nature and humans from an interdependent perspective. Heaven and Earth take humans as the basis of their existence, and only after humans discover the law of nature and the sacredness behind it can a deep interdependence between Heaven and Earth and humans and nature and humans be established. However, as modern humans emerge, the interdependence between Heaven and Earth and humans collapses as they destroy nature and lower the authority of Shindo (divine order). Haewon Sangsaeng (the resolution of grievances for mutual beneficence) and Boeun Sangsaeng (the reciprocation of favors for mutual beneficence) is the solution to reestablish the interdependence that has been disconnected between Heaven and Earth and humans and nature and humans. The practice of Haewon Sangsaeng through Gongbu rituals is the way to restore interdependence between nature and humans. The process of humans achieving Dotong (mastery of the Dao) through religious practices is the practice of Boeun Sangsaeng, and humans will be reborn into Injon (Human Nobility or 'divine humans') with ecological nature and enjoy an eternal interdependent relationship with nature. In summary, Sangsaeng in the context of Sangsaeng ecological theory is the idea and practice of allowing nature and humans to restore their interdependence and live on eternally.
