  • Background: Ecologists have achieved much progress in the study of mechanisms that maintain species coexistence and diversity. In this paper, we reviewed a wide range of past research related to these topics, focusing on five theoretical bodies: (1) coexistence by niche differentiation, (2) coexistence without niche differentiation, (3) coexistence along environmental stress gradients, (4) coexistence under non-equilibrium versus equilibrium conditions, and (5) modern perspectives. Results: From the review, we identified that there are few models that can be generally and confidently applicable to different ecological systems. This problem arises mainly because most theories have not been substantiated by enough empirical research based on field data to test various coexistence hypotheses at different spatial scales. We also found that little is still known about the mechanisms of species coexistence under harsh environmental conditions. This is because most previous models treat disturbance as a key factor shaping community structure, but they do not explicitly deal with stressful systems with non-lethal conditions. We evaluated the mainstream ideas of niche differentiation and stochasticity for the coexistence of plant species across salt marsh creeks in southwestern Denmark. The results showed that diversity indices, such as Shannon-Wiener diversity, richness, and evenness, decreased with increasing surface elevation and increased with increasing niche overlap and niche breadth. The two niche parameters linearly decreased with increasing elevation. These findings imply a substantial influence of an equalizing mechanism that reduces differences in relative fitness among species in the highly stressful environments of the marsh. We propose that species evenness increases under very harsh conditions if the associated stress is not lethal. Finally, we present a conceptual model of patterns related to the level of environmental stress and niche characteristics along a microhabitat gradient (i.e., surface elevation). Conclusions: The ecology of stressful systems with non-lethal conditions will be increasingly important as ongoing global-scale climate change extends the period of chronic stresses that are not necessarily fatal to inhabiting plants. We recommend that more ecologists continue this line of research.

  • The purpose of this paper is to introduce two integrated urban development projects in Japan that take full advantage of flood-control reservoirs: the Tetsugakudo Park Collective Housing Development Project and the Koshigaya Lake Town Project. The former project - implemented cooperatively by the Tokyo metropolitan government in charge of river management, Shinjuku and Nakano wards (in Tokyo) responsible for park management, and the Urban Renaissance Agency, a housing project developer - set a significant precedent for three-dimensional river use by realizing the three-dimensional integrated development of a flood control reservoir, a park, and collective housing. The Koshigaya Lake Town Project, launched as a drastic storm water management measure for a low-lying area often plagued by flooding, has achieved a sustainable coexistence between the waterfront environment and the urban living environment, with an artificial flood-control reservoir as the core for urban development. This project is fully committed to environmental coexistence through the optimal use of local environmental resources, with the cooperation of the central government, Saitama Prefecture and Koshigaya City.

  • The purpose of this review is to establish a groundwork for building a more comprehensive conceptual framework within which various aspects of sibling relations and factor related to sibling behaviors con be explained and integrated. Descriptions of the trends and shifts in sibling studies are made in terms of their themes, variables, basic perceptions and general approaches, and analyzes of current state of sibling researches are made with relation to the conceptual aspects of the studies, namely, their standpoints on the issues of sibling variations, the sources of variations, and basic units of analysis, their reliance or emphasis on different methods, and their interests in the mediation processes. It is recognized that research variables have been successively differentiated and used in diversified manners and family ecology and systems theory viewpoints have been incorporated into the understanding of sibling relations. A triad in its full meaning, rather than a dyad or a partial trial, is proposed as a unit of analysis in order for the researchers to be able to examine and describe the true interactional aspects of family relations involving sibling relations. The concepts of coexistence and interaction are proposed as key concepts os that the inconsistencies in findings, differing viewpoints, contradicting conceptions , and contrasting approaches can be interpreted and integrated into a unified system of theories on siblings. The coexistence of similarities and differences in reality. the inevitability of interaction between individual variables and environmental variables and between within-family environmental factors and our-of-family environmental factors, and the need for the joint use of intrafamilial and extrafamilial approach are acknowledged. Attention is also drawn to the mechanism characteristics and the directionality of the mediating processes of mediating variables between a variable and its effects.

  • Farm economy is getting worse because of the free trade trends in agriculture sector and unreasonable application of market economy principles to agricultural products. And The worldwide issues of environmental pollution as well as want of food, water and energy make human future be anxious. In addition, consumers raise questions in argument about safety of foods produced by traditional farming or imported. So I propose the urban-rural living community movement(URLCM) as an alternative plan for sustainable domestic agriculture. URLCM based on environmentally friendly agriculture and community consciousness will be able to solve many of present issues on agriculture and rural society through incessant interchanges between urban and rural community. This URLCM has to be basically founded on principles of symbiosis-coexistence and life circulation. So those that have to be driven forward arc organizing producers and consumer cooperatives, making environmentally friendly rural region and products, combining with consumer cooperatives, training the participants and so forth.

  • The ecological environment planning begins with the awareness that human are a part of ecological system. A recent issue, LOHAS (Lifestyle of Health and Substantiality), will be defined as a consumption trend which values highly health, social justice, economy, self development and sustainable life. LOHAS aims at coexistence with human and nature, pursue a sustainable development and it could be an alternative for SHS(Sick House Syndrome). This research tries to show the case analysis in coexistence in human and nature which LOHAS aims at. The design space applied the concept of LOHAS(renewing, reusing and recycling) will maintain healthy lives of the present and the future. In this context, it tries to solve the problems in architectural space and show the new possibilities in it

  • This research is to analyze ethics in fashion design for more valuable and sustainable human life against the increasing alienation of the human being, the global ecological crisis resulted from contemporary consumption society. I expect that it can be helpful to plan ethical fashion design practice more effectively. For this, the documentary study and practical case study have been executed. The results are as follows. The ethics in design can be defined as the responsibility to reform the social, environmental problem of consumptive design, to sustain together without human alienation, environment disruption and to do social good for total human being ultimately. The ethical design practice means to suggest solutions to problems of human rights and environment and to act willingly. Based on this, ethical fashion design appeared as responsible design solution which has two directions. One is the fashion design for coexistence and sharing, including the design for all which considers even underprivileged minority, the design to promote public issues as well as to donate some profits. The other is the eco fashion design for sustainable environment, including eco-friendly design which is reductive and slow in whole design process, the design to inform the seriousness of environmental crisis as well as to donate some profits. The last one of the most important ethical responsibility as fashion designer is to abide by vocational ethics, that is, the prohibition of design piracy.

  • The purpose of this study was to analyze characteristics of environmental awareness and environmental worldviews on environmental UCCs which made by 27 pre-service biology teachers, and relationship between environmental awareness and environmental worldviews of them. Environmental worldviews were divided into planetary management worldview, stewardship worldview and environmental wisdom worldview. As for theme fo environmental UCCs, most of pre-service teachers chose themes such as environmental destruction, environmental protection, environmental conservation and coexistence with human and environment. Themes of environmental UCCs were somewhat different between females and males. Female pre-service teachers preferred UCC themes related to human's daily life as a consumer but males preferred to environmental protection. Many pre-service teachers referred that major cause of environmental problem was development of environment. Most of them had envionmental wisdom worldview, and tried to use fear appeal to express ways of solving of environmental problems and envieonmnetal worldviews. After making environmental UCCs, more pre-service teachers had envionmental wisdom worldview. This result implies that it is necessary to develop pre-service educational programs realted to environmental worldview formation.

  • It seems to be difficult to bridge between human and nature. All depictions of nature are not necessarily reflections of reality. Thoughts are projected into nature, then nature will reflect us. The world is composed of natural and cultural environment. There are differences between depiction of nature based on correspondence and construction of world. Environmental aesthetics is an emerging field of study that focuses on nature's aesthetic value as well as on its ethical and environmental implications. Allen Carlson, a pioneer in environmental aesthetics, provides challenges as well as a wealth of resources for those who would appropriate his ideas in the service of environmental protection. Carlson's positive aesthetics, his focus on the functionality of human environments, and his integration of aesthetics and ethics have great import for those seeking to use aesthetics to assist in addressing environmental controversies. Environmental ethics would benefit from taking environmental aesthetics more seriously. Environmental aesthetics is an emerging discipline that explores the meaning and influence of environmental perception and experience on human life. Arguing for the idea that environment is not merely a setting for people but fully integrated and continuous with us, Arnold Berleant explores the aesthetic dimensions of the human-environment continuum in both theoretical terms and concrete situations. Aesthetic experience is always contextual. The aesthetic aspect of any human habitat is an essential part of its desirability. The aesthetic perception of environment shows us the reciprocity that constitutes both person and place. The genuine beauty lies in the coexistence and harmony with natural environment.

  • Purpose: The purpose of this study was to attempt an accurate understanding of the quality of life for the children and provide basic materials for application to nursing research, intervention and further theoretical development. Method: Data obtained from such research methods as the lexical and literature review were analysed according to Walker and Avant's(1995) process of concept analysis. Results: As a result of analysis, it was found that the attributes of the concept of the quality of life for the children included value/acceptance, family relationship, safety, good relationship with friends, right of children, school life, parent relationship, leisure, economical stability, not child abuse, and health. There was the coexistence between antecedent element and the outcomes of subjective judgement - health, family, economic strength, education, friends, welfare, social-cultural environment which indicates the coexistence of positive and negative emotions. Conclusion: nursing intervention should be provided for children by concentrating focus on the coordination of internal and external situations in order to prompt them to express their life with positive emotions. Experiential reference was used to suit the purpose of this study based on the use of objective and subjective indicators, and the development of the instrument considering the children were proposed because of the absence of the unified measurement instrument.
