  • LOHAS(Lifestyles Of Health And Sustainability) drinks were prepared by the addition of mulberry leaf powder(MLP) at various levels(0%, 5%, 10% and 20%). Their characteristics of the drinks were examined according to antioxidant activity and sensory evaluation. In the sensory evaluation, there was no significant difference between the control group(0% MLP group) and 5% MLP group for overall quality. For the proximate compositions of the LOHAS drinks, moisture, crude ash, crude protein and crude fat were all increased as the ratio of MLP increased. For the mineral contents, the amounts of calcium and magnesium were increased, but sodium, according to adding levels of MLP.

  • This study was conducted laying the focus on finding the mutual action between the substantial ecological value and economic system in the national land, and calculating the environmental carrying capacity and sustainability of the national land using the emergy synthesis. Particularly, this study pays attention watchfully to the reality that the analytic framework to analyze sustainability is not arranged well, as the concept of sustainable development considering environmental carrying capacity, which becomes a widely discussed topic today, is defined differently according to the subjective views of respective researchers, and the situation which needs in-depth evaluation on the interaction between nature and economy which becomes the fundamental of sustainable development. This study also aims at groping for correct direction for the national land development by calculating the environmental carrying capacity and index value which is appropriate to the national land and providing the framework for preparing the policy to induce the sustainable use and management of the national land. The concept of emergy synthesis which is used for the evaluation of environmental carrying capacity and sustainability in the national land, as in this case, can notify the information on current situation of the national land as well as explain how the national land transforms according to time pass (the role of information synthesis), and gives knowledge if the national land policies advances toward the direction of sustainable development (the role of policy evaluation and observation). Emergy synthesis also can take role for selecting best policy on the process of decision making on the exploitation of the national land (the role on the process of decision making).

  • This study was carried out to find out the possibility for developing methodologies on the index for forest sustainability and to assess sustainability indices of metropolitan and provincial districts based on conditions of their forest health and management programmes in Korea. To find out some indicators to be utilized in developing the forest sustainability indices, total 84 possible indicators were selected and combined from 69 major programmes contained in the 4th Forest Development Plan and the Forest Vision for 21st Century and other 15 indicators selected separately from other forest policies. Those candidate indicators were reviewed throughly under evaluation processes and 33 indicators were finally chosen in developing the forest sustainability indices. Those indicators were classified into 3 categories, namely indicators for pressure, state, and response. Forest health could be represented by pressure and state indicators, while forest management programmes could be assessed by response indicators. Scores of importance for each indicator were assigned through Delphi survey and analyzed to project the extra weight value by summing rankings given to each index an applied to the standardized value of each index. Forest sustainability indices of metropolitan and provincial districts were analyzed and compared, based on relevant data of the year 2002. This study was kind a preliminary one in forest sustainability index and the names of metropolitan and provincial districts were not identified in this study. The indices could be very valuable in assessing quantitatively the level of forest health and intensity of forest management programmes in each districts and comparisons could be made among them, if all self-governing districts agree unanimously on the indices of forest sustainability and relevant indicators chosen in the study.

  • To assess the water resources sustainability, many indicators and methodologies have been suggested by international organizations and developed in other countries. However, in the previous studies, some of indicators were unsuitable for assessing the sustainability of water use and management in Korea. Thus, in this study nSl(Water Resources Sustainability Index), a multi-variable index, was created by consideration of environmental, social, and economical criteria. Relative weights for components, indicators and sub-indexes, were determined by employing the Analytic Hierarchy Process. In order to extract the indicators related with water resources sustainability, the data related with water resources and indicators suggested in various field were compared and thoroughly reviewed. These indicators were classified into four groups; Economic Efficiency Index, Social Equity Index, Environmental Conservation Index, and Maintenance Capability Index. The weight of each component were decided by the survey of 127 specialists in water resources and sustainability. The result of survey represented that efficiency and equity of water use and water quality for river restoration are major issues in enhancing the water resources sustainability In addition, it was found that investment and public participation should be considered for sustainable water use.

  • Ecotourism, which is attracting attention as a method of sustainable tourism, is a tourism that aims to preserve the environment of the tourist area, to improve the participation and welfare of residents in the tourist area, and to improve the tourism experience and education. Ecotourism is a field that is developing at a faster rate than other areas of tourism. With the pace of growth, ecotourism faces new challenges for sustainability. This study focused on institutional sustainability in addition to economic, socio - cultural and environmental sustainability to assess the sustainability of ecotourism destinations. The results of this study confirm that institutional sustainability should be given priority for sustainability of ecotourism. Examples include the designation of protected areas, the establishment of ecotourism management entities, the regular investigation and research of academic purposes, the management of tourist visits and tourist information, the cooperation and participation of local residents, and the activities of commentators and managers. The attractiveness of ecological resources was also influenced by the access of tourists and the influence of local residents. Therefore, careful attention should be paid to the approach of tourists and the use of land by local residents in ecotourism. In the future, the operation of the visitor center, the professional education and mission of the interpreters' ecological resources, and the training and guidance of tourists by interpreters will be very helpful for the sustainability of the ecotourism destination.

  • Major cities have strengthened their efforts to improve the environmental function of the urban forest through aspects of quantity and quality. Yet, it is difficult to propose both long-term improvement and management policy direction continuously due to a lack of evaluating method that social needs could be reflected. After all, effective strengthening of the function of an urban forest, composed of social and biotic environments, is essential to create evaluation criteria. Such data reflects a quantity variation and identifies the distribution and habitation of biotic sources as well. An assessment of utilization possibilities presents such values as a green connectivity, an ecological healthiness, and usage and access opportunities. Consequently, this research was executed to create an urban forest sustainability index that proposes a management and policy direction based on the evaluation of quantity and quality aspects. This study was processed by the following steps: a degree of importance of ecological aspect, a sub-classification index choice, and an examination of adequacy. This research was conducted from premises that urban forest had another functions comparisons to a natural forest. As a result, a criteria of sustainability should be considered to evaluate an ecological aspect, as well as the social and management aspects regarding human disturbance. This research is designed to develop an evaluation index for ecological aspect. In order to evaluate the ecological healthiness of an urban forest, a vegetation index considers aspects of related rarity, damage possibility, naturalness, area, and diversity. In a wildbird index-related study, forest duration and area were selected. Finally, a variance analysis is presented, inclusive of stability, naturalness, diversity, potentiality, and possibility of wildlife inhabitation, which is indicative of an urban forest sustainability index.

  • Sustainable development has been the key concept, both in economic policies and in environmental management. On the basis of an systems ecology perspective, this suggests the sustainable development of Korea\`s natural environment and economic activity using the EMERGY evaluation. The total EMERGY use(7,730E20sej/yr) in Korea is 81 percent from imported sources, fuels and goods and services. The ratio of outside investment to attracting natural resources is already large, like other industrialized countries. Continued availability of purchased inputs at a favorable balance of EMERGY trade, currently about 2.85 to 1 net EMERGY, tis the basis for present economic activity and must decrease as the net EMERGY of purchased inputs including fossil fuels goes down. EMERGY yield ratio and environmental loading ratio were 1.23 and 20.30, respectively. The population level is already in excess of carrying capacity. Its carrying capacity for steady state on its renewable sources is only 2.2 million people, compared to 45.9 million in 1977. EMERGY sustainability index is therefore less than one, which is indicative of highly developed consumer oriented economies. Until now the development of a country has been achieved by the economic growth, but it can be sustained in the long run by the use of renewable resource systems. the efficiency of energy usage, and the transformation of the social-economic structure based on an ecological-recycling concept.

  • The purpose of this study is to develop the evaluation factors for formation of the future - oriented rural residential environment and to derive the importance of this evaluation factors. The main research methods are network analysis using Net-miner, AHP analysis and importance analysis for experts. The main research results are as follows. First, 6 factors for evaluation rural residential environment(environmental-sustainability, communality, self-reliance, aesthetic, enjoyment, settlement), 3 sub-factors of each factors, and key physical facilities(10 for rural center and 28 for rural villages) were derived by literature analysis and network analysis on it. Second, key priority factors that should be considered in physical formation of rural residential environment was deducted by AHP analysis. Improving accessibility of living services in the settlement factor, improvement of garbage collection and wastewater treatment system around the residential area, and ensuring topographic continuity in the environmental-sustainability factor was derived as a priority factors. Third, as a result of evaluation of the importance of physical facilities in the rural residential environment, there was a high demand for cultural welfare facilities in common. However, when compared with the villages where the harmony between the natural environment and the living environment is emphasized, convenience of living and accessibility of transportation were important in the rural center. These results suggest that solving the qualitative conditions as residential environment will help to attract new population. This study will contribute to enhance the qualitative level of the rural residential environment by suggesting strategic priority items when carrying out projects related to the rural residential environment creation in the future.

  • The object of this study is the introduction and the application of Ecological Footprint(EF) for sustainability of regional people activities. It is a tool for the evaluation of specific projects through various lifestyles or consumption to area of broad policy and budgets. But in Korea there is no assessment for consumption level of human activities by EF. Therefore this study try to analyse ecologically productive land for human activities of Cheju-island in order to assess the sustainability in Cheju and compares with another industrized countries. We analyze the human activities level of Cheju-island then the EF is about 0.9(ha/cap). This value is not more than another countries like Canada and United States. EF assists in choosing technologies, policies and Life Cycle Assessment(LCA) which can perform a certain task with the smallest ecological footprint. It will help society to avoid collapse and move towards sustainability and ecological efficiency.
