  • The objective of this research was to develop ecological multi-metric models using natural fish assemblages for a diagnosis of current stream health condition, and apply the model to nationwide lotic ecosystems of the Geum River, the Youngsan River, and the Sumjin River. The ecological stream health model was based on the index of biological integrity (IBI), which was originally developed in North American streams by Karr (1981), and the Rapid Bioassessment Protocol (RBP), which was scientifically established by the US EPA (1999). The metric numbers and metric attributes were partially changed for the regional applications, so the scoring criteria was modified for the assessment. Overall, metric values, based on the IBI calculations, reflected conventional water quality characteristics, based on nutrient regime, and agreed with results of staticeco-toxicity tests. Some stations impaired in terms of stream health were identified by the IBI approach, and also major key stressors affecting the stream health were identified by additional evaluations of physical habitats. Our preliminary results suggested that biological integrity in stream ecosystems was largely disturbed by habitat degradation as well as chemical pollutions. This new approach would be used as a key tool for ecological restorations and species conservations in the degraded aquatic ecosystems in Korea and applied for elucidating major causes of ecological disturbances. Ultimately, this approach provides us an effective management strategy of stream ecosystems through establishments of ecological networks in various watersheds.

  • Various methodologies have been proposed in discussions of sustainability to meet the needs and sustenance of both civilization and the ecosystem. Among them, the modern concept of biomimicry is emerging as a way to meet both the concepts of sustainable 'development' and 'society', due to its philosophical position encompassing the human-centered world view and the non-human-centered view of ecocentrism. Therefore, in the field of design in which it is necessary to take responsibility for environmental and social problems, this could be a good way to solve these issues. Biomimicry design can generally be divided into three stages: form, function, and ecosystem. From the point of view of ecological sustainability, ecosystem imitation is the most advanced and appropriate design approach that can solve the problems or even prevent them. Accordingly, this study derived a biomimicry design approach in the ecosystem imitation stage based on the concepts of biomimicry, ecological sustainability, and ecological aesthetics. The detailed approaches are 'imitation of the natural providence', 'imitation of the ecosystem's creation process', and 'imitation of the ecological cycle'. This study investigated and presented cases, such as the design imitating the ecological mechanism of microorganisms and the work using mark-making based on the derived design approach, because it could be too conceptual and idealistic by itself. Through this, we explored a method of applying and visualizing the concept of biomimicry in textile design at the ecosystem imitation level and showed its feasibility, although it still has difficulties in practical use.

  • Ecological Risk Assessment (ERA) supports a decision-making process such as establishment of environmental quality criteria. Soil quality criteria (SQC) are essential to protect soil organisms from the exposure to various soil contaminants. In this study, ERA methodologies of advanced countries for soil pollution were extensively compared to propose the ERA approach suitable for soil ecosystem in Korea. The soil ERAs in European Chemical Bureau(ECB), The Netherlands, and Canada can be classified as deterministic ecological risk assessment (DERA), and probabilistic ecological risk assessment (PERA) based on species sensitivity distribution (SSD). We propose three ERA methods according to abundance and reliability of soil ecotoxicity data. The method considered land use such as residential/agricultural, and industrial/commercial uses. The taxonomic groups of soil organism were classified as 'Class' level including different trophic levels (Magnoliopsida or Liliopsida, Clitellata, and Insecta or Secernentea). This study can be used to estimate the soil quality criteria to protect soil biota.

  • The purpose of this study is to suggest an environmentally friendly energy system of ecological architecture, with the reference to foreign cases, judge feasibility of it. The ecological architecture is very similar to the natural ecosystem. There is growing international scientific consensus that human activities are having a discernible effect on the global climate. Therefore, with a precise understanding of the concept of ecological approach and concrete perception of the necessity it, an establishment of planning which recognizes the ecological architecture as a organism a same time, ensures diversity, stability and cycling stemmed from the ecosystem to various activities through a ecological structure shall bring the introduction of substantial ecological architecture into domestic realm. As a result, in this Age of industrial science, We are proposing useful materials and suggestion regarding the ecological architecture planning of korean cities, by preestimating the characteristics of a city heading toward the Age of the new ecological environment.

  • 본 연구에서는 다양한 생태계의 보전 및 생물다양성 보전과 증진을 통한 생태계의 지속가능한 이용을 위하여 우리나라 생태계 보호지역 확대를 위한 평가기법과 이의 정책적 활용 방향을 제시하였다. 이를 위하여 첫째, 생태계 보호지역 평가기법 활용 현황을 분석하였고, 둘째, 생태공학 기법을 기반으로 지역 규모의 생태계 보호지역 평가를 위한 개념 모형을 제시하였으며, 셋째, 이러한 분석 결과의 활용 방안을 제언하였다. 국외에서 보호지역 지정 시 다양한 분석 모형을 활용하고 있는 것과 달리, 우리나라의 경우 장기 생태계 모니터링 및 생태연구 자료가 부족하여 보호지역 지정 분석기법의 개발 및 적용이 미흡한 상태이다. 특히 미소 규모나 지역 규모보다는 국가 규모의 분석에 기반한 보호지역 지정이 주를 이루고 있어 지역 규모의 다양한 생태계가 반영되지 못하고 있다. 보호지역의 합리적인 지정과 효과적인 관리를 위해서는 다양한 인자들과 인자들 간의 상호작용을 고려한 지역 규모의 종합분석이 필요하며, 이를 위하여 본 연구에서는 생태공학 기법을 토대로 한 보호지역 분석의 개념 모형을 제시하였다. 본 연구에서 제시한 생태계 보호지역 분석은 다양한 생물 인자 및 비생물 인자, 그리고 이들의 상호작용 및 미래 환경변화를 고려한 각 지역 생태계의 특성을 반영하기 때문에 현재 우수한 생태계뿐만 아니라 앞으로 중요하게 보호해야 할 생태계를 보호지역으로 편입할 수 있는 근거를 제시하였다. 그러나 본 연구에서 제시한 분석 기법의 충분한 활용을 위해서는 각 지표항목과 지표항목에 속하는 인자들에 대한 개별 생태연구 자료 및 공간자료가 필요하다. 이러한 분석의 한계를 해결하기 위해서는 장기간의 생태자료와 종별 서식지 환경조건에 대한 연구 자료가 필요하며 서식지 모형, 생태모형, hybrid 모형 등 경관생태모형을 활용한 분석이 필요하다.

  • Challenges brought by applications of advanced technologies in education call for new approaches that can best ensure the provision of quality e-learning experiences. This paper presents an ecological approach as one of such approaches to quality assurance in e-learning that can monitor, assess and improve the effectiveness and the links between the various elements of e-learning. The ecological model for QA in e-learning emphasizes interrelation transactions between elements (e.g. providers, learners, cultures and policies) and systemic integration of those elements, and stresses that all these elements within a QA system play an equal role in maintaining balance of the whole. The model focuses attention both on individual and societal/cultural environmental factors as cornerstones for QA efforts in e-learning. It addresses the importance of QA efforts directed at changing QA transactions from provider-centered to 'all stakeholder-oriented', from one-size-fits-all model to 'globally oriented, locally adaptive model' and from control framework to 'culture creation framework'.

  • Object of this study is to suggest the plan for natural vegetation restoration and management by ecological approach. The concept of biotope planting technique was introduced in order to restore the natural vegetation in the northern part of Mt. Nam in Seoul, and Quercus mongolica forests was surveyed so as to obtain the basic data. This study focused on the vegetational context between northern part of Mt. Nam and develop-reserved site. The results are following ; 1. It is suitable to plant 25~30 trees in $100\m^2$ with trees of DBH 10cm and below at intervals of about 2m in canopy layer. In the case of subtree layer of DBH 2cm, about 30 trees were planted at an Intervals of 1.5~2m around in $100\m^2$. 2. In the last step of nature vegetation restoration, it is desiable that canopy density is $5/100\m^2$ and 녀btree one is 10~20/$100\m^2$. 3. Management plans was proposed to use the native species of Mt. Nam around and to investigate the ecological situation once a year such as species introduce, dead-tree, soil, fauna etc.

  • The purpose of this study is to overview foreign trends in the study of the landscape ecology through new framework of landscape ecological studies and to suggest possibility and limitation of introduction of landscape ecology studies in Korea. Because of historical reasons rooted in different disciplines, landscape ecology of the present time is not unified at all. Therefore, landscape ecology should be understood in an integrative manner accommodating different views and various aspects of landscape(NOOS, GEOS, BIOS). Facing the increasing environmental problems and the goal of sustainable landscape, the principle of a holistic approach complementarity and transdisciplinarity outlined in this paper (esp. connection physical-materials and cognitive system) might help to understand the characteristics of landscapes and landscape ecology. Important steps towards this direction are the landscape survey, diagnosis, the identification of landscape functions, the development of landscape evaluation models and landscape planning system. Recently there have been a few landscape ecological researches in Korea, which tells there have been strong needs to solve practical landscape problems caused by the rapid socioeconomic growth for several decades. However, almost of this studies are focused on cognitive and visual aspects of landscapes defined boundaries of disciplines. But for more holistic approach complementarity and transdisciplinarity in landscape ecological studies, many other aspects such as the consideration of geoecological and bioecologocal variables, preperation of ecological basic data(mapping) and the development of landscape planning as a tool for practical application should be integrated into the whole landscape system.

  • The purpose of the study was to develop family-based intervention program to be implemented and disseminated via "Healthy Family-Support Center." This preventive-empowerment program was designed to intervene with parenting mildly handicapped children enrolled at integrated kindergarten. The theoretical backgrounds employed were ecological theory, preventive family-based intervention approach, and theraplay theory. The pretest-posttest control-group design with random assignment was applied. The research model yielded a significant intervention effect(t=-1.294, p<0.05) on mothers' parenting stress. With proven effectiveness of family-based intervention program, the study further discussed why an ecological, family-based intervention model was a relevant alternative to investigate issues in family welfare, and why an individualized family service plan was a relevant tool to deliver services-in-context for the families who needed supports from exo-and macrosystems.
