EFA production systems have through necessity resulted in the development of innovative practices for weed, pest and diseases control, for example, using ducks and snails for weed control in paddy fields. These practices began to be introduced in the early 1990's and the techniques have become more popular and have been adapted to suit regional conditions. In this study, the production practices, productivity and economic performances of organic and non-chemical rice farming adopting ducks and snails for weed control were compared. In the production practices, Korean organic and non-chemical farming seem to have several concerns in terms of sustainability. It comprises lack of resistant variety use and rotational cropping system as well as high dependency upon external inputs such as organic fertilizer and farming materials for pest control. The production level of organic farming is approximately similar level but 20% higher income than non-chemical farming, while, when it was compared with conventional farming organic farming showed 20% lower productivity but 20% higher income. Organic farming shows 15% to 18% higher profits than non-chemical farming as the snail-using organic farming tends to have higher income and lower input costs than duck-using organic farming. This may encourage more farmers to convert to organic production using these techniques than simply non-chemical farming in the future. This organic conversion could be more promoted by policy intervention. However, it may result in increased supply and therefore decreased prices for organic rice in the long term unless further market demand occurs. Balanced policy measures considering production as well as marketing and consumption are urgently required for the sustainable development of organic farming.

The world's food production systems are becoming an area of great concern for both human and ecological health. Research has identified that one of the greatest threats to sustainability is conventional industrial agricultural systems and the high energy and material cost they require to function. The organic food movement is contributing as promising alternative to the current dominant model. Over the last 50 years it has developed into the most visible brand for a healthier and more environmentally sustainable food system. However, to achieve its full potential there are still a number of hurdles which must be overcome to make organic products a more viable and appealing option for consumers. This paper provides an overview of key research that has been conducted on why consumers are buying organic products, what they are buying and what is preventing them from purchasing more. It concludes that the key challenge is for the organic food movement to convince existing consumers of the superior 'value' of its products. In addition there are a number of methodological issues associated with analysing the market for organic products as well as issues of limited distribution, intermittent availability and high prices that are currently preventing increases in sales. Recognition and management of these barriers could contribute to more effective targeted research into consumer food purchasing motivations and subsequently the development of more sophisticated marketing strategies that assist in maintaining integrity with consumers and fending off challenges from conventional as well as other complementary food systems such as local food movement. And finally to achieve these market growth strategies the organic food movement will need to cope with its diverse constituency - ranging from global corporates through to local production and consumption - and provide attractive opportunities to individuals and business at all stages in supply chain whilst retaining credibility with government to ensure ongoing policy support.

This study was carried out to investigate the sustainable agriculture of no-tillage technique to minimize tillage problems under rain interception green house condition including recycling of the ridge and the furrow for following cultivation in Korea. Chemical properties in soils were investigated at 3-years after cultivation at conventional tillage [CT; 2-years no-tillage (2009-2010) and 1-year (2011) tillage] and no-tillage [NT; 2009-2011] field. Soil pH maintained between 5.8 and 6.0 irrespectively tillage and no-tillage. Salinity (EC), contents of total nitrogen (TN), cation exchange capacity (CEC), and exchangeable cations (K, Ca and Mg) in soil were remarkably higher in CT than in NT treatment. Salinity (EC), contents of OM, TN, CEC, and exchangeable cations in top soil and subsoil indicated higher deviation in CT than NT treatment. Organic matters and inorganic matters in soil were positive (+) correlation. Suppression of pepper growth and increase of yield were observed in no-tillage soil compared with tillage soil. These results indicated that no-tillage technique in crop culture could play an important role with respect to chemical properties in silt loam soil.

Small and medium sized enterprises' (SMEs) environmental performance and activities have been often of great concern toward sustainability as they have been playing a critically important role in the economic and industrial development. Among many initiatives to engage SMEs into the sustainability framework, Supply Chain Environmental Management (SCEM) of large companies has a great potential to persuade SMEs to adopt environmentally improved activities. This study investigated the relationship between SCEM approaches of large companies and environmental activities of SMEs in the Korean electronics industry. A postal questionnaire survey was used as a data collection method, and factor analysis and regression analysis were applied to analyse the collected data. The empirical findings suggested that SCEM approaches of large companies have positive impacts on environmental activities of SMEs. Among SCEM approaches, the collaborative approach was more effective than the arm's-length approach. Additionally, this study found positive impacts of trans-national SCEM approaches on SMEs' environmental activities.

Land-use changes have made considerable impacts on humans and nature such as biodiversity and ecosystem services. It is recognized as important elements for land use planning and regional natural resources conservation to identify the major causes of land use changes and to predict a process of changes and effects. This study, by using a spatially explicit Dyna-CLUE model, analyzed correlations between driving factors, quantified location characteristics of different land use types using logistic regression analysis and examined future land use changes and its effects in Yangpyeong and Yeoju region. We expected land use changes based on the three scenarios with different future land demands and simulated future changes for spatial variations of land use for the 20 years. The outcomes shows that larger change was found in agricultural areas than forest areas, based on the change in built-up areas. The changes in forest areas, which were mainly occurred in edge area, were expected to affect a large impact on its ecotone. It was found to be the importance of the management of forest edge and the necessity of the environmentally sound and sustainable development in order to conserve natural resources of the region.

Firstly, the goals and the domains of contents of environmental education was classified in order to systematize the contents of environmental education which would be taught in each subject. According to these goals and domains of contents, the contents of 10 subjects (Korean Language, Ethics, Social Studies, Mathematics, Science, Music, Arts, Physical Practicum(Technology and Heme Economics), English were analyzed. The norms in the analysis of the goals of environmental education by each subject were 4 domains: information and knowledge, skills, value & attitudes, & action and participation. The norms in the analysis of the contents of environmental education by each subject were 11 domains: natural environment, artificial environment, population, industrialization/urbanization, resources, environmental pollution, environmental preservation and measures, environmental sanitation, environmental ethics, environmentally sound and sustainable development(ESSD), and sound consumption life. As a result, it was found that all the 4 domains of goals in environmental education could come true. Furthermore, the goals of environmental education were found to be reached in the subjects of Korean Language, Music, Arts, Physical Education, Mathematics, English, etc., which had been thought to have nothing to do with environmental education. It was also found that the contents of each subject could deal with its own unique environmental contents. The result of this study can keep all subject from overlapping in environmental contents, and can make the most of each subject’s characteristics. Also, the result of this study will be referenced in developing the teaching and learning materials for environmental education according to each subject.

The purpose of this research is to determine the deterioration characteristics of high-rise and high-density apartment complexes in 1st period new towns in order to regenerate apartments as sustainable residential environments in Korea. For this purpose, the level of deterioration was evaluated by using 'evaluating indicators of the level of deterioration of high-rise and high-density apartments'. The deterioration characteristics were determined inclusively and concretely based on evaluation results. In addition, the deterioration level according to residents' awareness of the deterioration of their apartment was evaluated. This study was conducted by methods of field data collection, staff interview, field measurement, and resident survey according to the measurement of the evaluating indicators. And the re-organized questionnaire based on the evaluating indicators was utilized for a survey of resident's awareness. The results are as follows: In the physical dimensions of apartments, the deterioration characteristics included deteriorated equipment and a decline in structural performance due to the aging of the apartment, a shortage of parking spaces, and the low flexibility of the bearing wall structure, etc. In terms of the social dimensions, the apartments showed an increase in the number of elderly households, a shortage of community facilities, and a lack of the opportunity for community participation etc. In terms of the economic dimensions, the apartments showed limitations in maintenance & repair and a lack of environmentally friendly features.

As sustainable growth has been emphasized in the field of transportation, the railway system has been promoted as an environmentally-friendly transport mode. However, mode shifts from other transport modes to railway have been sluggish. In this context, to enhance the understanding of railway's competitive advantages and disadvantages, this research evaluates travelers'preferences for public transport modes for inter-regional trips: such understanding should make it possible to formulate effective policy for promoting railways. To this end, passenger recognition of competitive transport modes has been measured by applying multidimensional scaling analysis for six major inter-regional public transport services - KTX, ITX-Samaeul, Mugunghwa-ho, premium express bus, general express bus, and airline. As a result, we can conceptualize the recognition similarity in two-dimensional space, and understand how travelers perceive the six major transport modes.

This paper presents a landscape design for the citizen plaza around the ˝Woojeongchongkuk˝(the 1st Korean postal building) where the ˝Gapsinjeongbyeon˝(1844 coup d´etat) occurred and which was once used as the ˝Jeoneoigam˝(a palace hospital). The site is located in 39 Kyeonji-dong, Jongno-gu, Seoul, and of which area is about 2,013$m^2$. The landscape design goals are to build traditional spaces which fit the traditional buildings and where people feel the old atmosphere; to build interesting spaces where people can learn the post and telegraphic history; and to build nature-friendly green rest spaces in the city. To achieve these goals, symbolic, traditional, educational, historical, and environmentally-friendly concepts are developed. With this concept the space is divided into two axis of the pst and telegraph of Korea. Along the two axis the Postage Stamp ˝Madang˝(yard), the Letter Garden, the Telegraphic ˝Ddeul˝(garden), the Communication Plaza, and the ˝Jeoneoigam˝(old palace hospital) and the ˝Gapsinjeongbyeon˝(1884 coup d´etat) Memorial Place are arranged. The Postal Stamp Madang which symbolizes the first Korean postage stamp is a space for studying history and evolution of stamps in Korea. The Letter Garden which symbolizes and formalizes a letter paper is composed with white bamboo trees which are planted linearly and long granite benches on which famous letters are carved. In the Telegraphic Ddeul which symbolizes the telegraph, the history of the telegraphic instrument and the telephone is exhibited. In the Communication Plaze which symbolizes future post and telegraph service extending to the world, the images of satellite communication, internet, webmail etc. are exhibited. The Jeoneoigan, and the Gapsinjeongbyeon Memorial Place is for memorializing the historic place and events. Throughout the whole place, various models and ceramic picture tiles about the post and telegraph and exhibited for effective education. In conclusion, sustainable management schemes for the site are suggested.
