  • In conceptual ecology, a concept does not exist independently but occupies an ecological niche in ecological environment. Among many biological concepts, genetic concepts are connected to several units including the genetics unit, and within the genetics unit the concepts of sub-areas are highly dependent on one another. For this reason, we analyzed conceptual diversity and conceptual proximity of genetic concepts through the ecological niche approach. For this purpose, we surveyed 995 9th graders. The areas covered in the survey were four genetic concepts: gene, chromosome, mitosis, and meiosis. The questionnaire presented biological concepts or terms related to each area, and the respondent marked the relevance between the presented biological concepts or terms and each area on a scale of 1~30 points. With 9th grade students, we analyzed the change of genetic concepts through class by the ecological niche approach. Through class, the total number of concepts increased in all of the areas, and the increase was smallest in the area of meiosis followed by mitosis, chromosome and gene. Relative density decreased with increases in the number of concepts. The conceptual diversity index also increased through class in all of the areas, and the increase was smallest in the area of meiosis followed by mitosis, chromosome and gene. In addition, difference in the relative density of concepts was reduced after class, and difference in the score of relevance was also reduced and consequently similarity among concepts increased. From these results were drawn conclusions as follows: First, through class, the conceptual diversity of genetic concepts increased. Second, through class, the conceptual proximity of genetic concepts increased.

  • This treatise puts with ecology that important topic is becoming in Multimedia age today. Is appearing to some meaning that symbol that. Is nature friendship and nature assimilation in korean verse and modern novel. And is the purpose to draw diachronic and synthetic thought between age and genre is forming by ecological imagination how. Our korean verse thinks of nature as residing space, and is singing life that is nature friendship and nature assimilation in relation of indivisibility sto of human and nature. And nature space of metaphor or symbol is forming by ecological imagination in the modern novel. Therefore, these two genres see that traffic is available in diachronic synthetic relation. First, must escape resolutely in ideas that literature is basing in actuality and search the literature-ecological imagination. Therefore, forward literature may have to look for the literature-ecological imagination with many interests to green literature ecology and show image that move constantly. And must approach appearing common view of nature and the literature-ecological imagination in principle of integration of expropriation and production now all round to our literary productions. Therefore, must do so that can be nature friendship and become practical education model that expropriation of ecological literary productions and production activity foster literary sensibility and imagination. Also, lively research and groping about each genre of a Korean literature are to premised in diachronic and synthetic veins I will. Method groping that adapt on New Age as defending peculiar special quality that founder is keeping korean verse with opened thinking may have to be spread more hard. Therefore, genre of novel can may ready the one clue to grope confrontation method naturally to secure new identity in new literature environment of digital age.

  • This study focused on the awareness and coping methods of psychological trauma and human suffering in the contemporary era after the development of posttraumatic stress disorder(PTSD) including the situations in the Korean society, and proposed principles for an alternative paradigm of trauma recovery. Trauma is defined as an 'external' stress causing chronic suffering mediated by memory, and the American Psychiatric Association approved PTSD in the Diagnostic and Statistical Manual of Mental Disorders in 1980. The development of PTSD empowered moral legitimacy to the victims, opened a successful way to treatment, and accomplished explosive amount of research in the area of neurobiology and cognitive neuroscience. However, this also narrowed the understanding of human suffering, and the importance of an alternative coping method which overcomes the limitations of technical intervention became overlooked. Moreover, the Korean society has an underlying mechanism of replacing the matter of trauma to a problem of an individual. This is shown among the historical context of splitting and denial, and among medicalized bureaucracy. Trauma should be acknowledged as a social suffering, and searching for an alternative paradigm is in need. This study suggested the following principles; seeking for truth and justice, survivor as the agent of recovery emphasizing the responsibility of the community, ecological adaptations of recent bio-psychological achievements, and finally putting emphasis on continuous discussions about the definition of recovery.

  • This study focuses on the ecological and environmental approach for marketing in the attempt to harmonize the objectives and resources of the organizations with the changing environment. This study presents the deductive and nomative method for analyzing recurrent marketing problem and contains seven chapters. The marketing environment is the place the company must start in searching for oportunities and in monitoring threats. It consists of all the actors and forces that affect the company's ability to transact can be divided into two componets-The marketing environment comperies a microenvironment consists of the actors in the company's immediate environment that affect its ability to serve its customers, namely, the company, market channal firms, customers, competitors and publics, the macroenvironment consists of the larger societal forces that affect all the actors in the macroenvironment, nanly, the demographic, economic, natural, technological and cultural forces. Most marketing executives took the phyisical environment for granted. Few consistered it one of the most dynamic elements in the totoal environment of business. However, two development have brought the physical environment to the forefront of business decision. The first has been labeled the ecological crisis-the polution and deterioration of air, water and land, the second is the accelerated depletion of the earth's natural resources. Currently, most product are designed to obtain an optimum combination of customer acceptances and production and distribution efficiencies. If we look to the future, products increasingly will be planned to obtain an optimum combination of market acceptance increasingly, efficiency and environmental protection. The entire ecological cycle of product will have to be considered.

  • This study reflects the regional context of Northeast Asian countries embodied in US-North Korean nuclear tension. The researcher uses the methodological inquiry of practical theology to analyze the political affairs and intertwine with religious education. The ecology of religious education to dismantle the threat of ethnic and racial discrimination such as white supremacy supports a shared pedagogy between students and their teachers in the narrative of Jesus to challenge all forms of oppression as the democratic presence of God.

  • In Korea, an olive flounder is very popular fish food item. However, due to the increasing human population, the present catches of the olive flounder may not be sufficient to satisfy the present demand. To increase the supply of the olive flounder, aquaculture has been begun. An interest in the aquaculture of the olive flounder has been increased recently because of its characteristics of good growth and high price in the market, However, the productivity of the olive flounder aquaculture depends on economic inputs such as fuels, facilities, and labor. The rapid growths of the olive flounder aquaculture and the concerns about economic and ecological sustainability have focused peoples attention on the aquaculture industry. In this study, an energy systems model was built to simulate the variation of sustainability on the aquaculture of olive flounder, The results of simulation based on calibration data in 1995 show that olive flounder production yield and asset slowly increase to steady state because of the law of supply and demand. The results of simulation based on the variation of oil price show that the more increase the oil price, the more decrease the olive flounder economic yield and asset. Energy sources required for systems determine the sustainability of systems. Conclusionally, the present systems of the olive flounder aquaculture should be transformed to ecological-recycling systems or ecological engineering systems which depend on renewable resources rather than aquaculture systems which depend on fossil fuels, and be harmonized with the fishing fisheries by the sustainable use of renewable resources in the carrying capacity.

  • 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.

  • The present work reviews some mechanism explaining how thin layer can develop in the near coastal zone. The existence of thin layer was observed by physical research methods later than classical biological approaches. The Richardson number, which is a ratio between the stratification and shear stress is crucial factor determining the occurrence of thin layer. Micro-structure turbulence seems to affect the plankton behavior, in particular the encountering rate. Encountering rate affects significantly feeding, reproduction etc. and this fact was proved by the mechanical simulation methods. Recently the Gyrotaxis was introduced to explain how thin layer occurs in the mixing layer. Such physical approaches to explain ecological problem will be prominent methods for marine ecological research area.

  • A morphological and molecular survey was conducted to determine the taxonomic status of Saussurea maximowiczii var. triceps on Jejudo Island. Although it tends to be smaller than S. maximowiczii with regard to typical quantitative characters of vegetative organs, including the plant height and leaf size, these two taxa cannot be distinguished from each other based on major reproductive characters, including the involucre and florets. Molecular data support the contention that S. triceps and S. maximowiczii are monophyletic taxa. Saussurea maximowiczii var. triceps is found to be an ecological phenotype of S. maximowiczii that has adapted particularly to the windy highlands of Hallasan Mountain on Jejudo Island.
