  • The effects of low impact development (LID) techniques, such as green roofs and porous pavements, on the runoff and pollutant load from an apartment complex were simulated using the Site Evaluation Tool (SET). The study site was the Olympic Village, a preexisting apartment complex in Seoul, South Korea, which has a high percentage of impervious surfaces (approximately 72% of the total area). Using the SET, the effects of replacing parking lots, sidewalks and driveways (37.5% of the total area) having porous pavements and rooftops (14.5% of the total area) with green roofs were simulated. The simulation results indicated that LID techniques reduced the surface runoff, and peak flow and pollutant load, and increased the evapotranspiration and soil infiltration of precipitation. Per unit area, the green roofs were better than the porous pavements at reducing the surface runoff and pollutant loads, while the porous pavements were better than green roofs at enhancing the infiltration to soil. This study showed that LID methods can be useful for urban stormwater management and that the SET is a useful tool for evaluating the effects of LID on urban hydrology and pollutant loads from various land covers.

  • Ahead of the second basic plan which starts in 2015, tasks needed to improve air quality and encourage green growth in the Seoul Metropolitan Area have been investigated. To date, many research findings indicate that climate change is ongoing and continues to accelerate in the Northeast Asia due to several factors, including unparalleled anthropogenic air emissions from China. An intensive field study is proposed that would target the Seoul Metropolitan Area and would be conducted in collaboration with the international scientific community. While focused on environmental issues in Korea, this study would also benefit the international community by providing insights that can be applied to address similar problems around the world. In addition to the basic plan's emphasis on improving air quality, there is a need to promote green growth through environment-friendly development. It is proposed that green growth be interpreted as a comprehensive concept, targeting all environmental pollution, rather than being limited to low-carbon goals. It is further proposed that the success of environment-friendly development be measured in terms of risk reduction, energy and resources conservation, economic benefits, and employment expansion.

  • 21st century has begun as an age of green growth. Development paradigms disregarding environmental sustainability are being changed and henceforth, stronger efforts should be made to discover and utilize green values. With the importance of green values, rural amenity which is in the spotlight as a new channel to change the way people think about depressed agriculture and rural community could be the key to discover green values of rural area. This study is to emphasize rural amenity and to rectify prejudiced and distorted contents of agriculture and rural community in agricultural highschool textbooks. By doing this, students of agricultural highschool who will lead agriculture in the future will come to recognize the importance of agriculture and rural area and discovering it's values. This study was done through analysis and development of contents in 39 kinds of textbooks of Agricultural highschool. A content analysis was employed to examine to what extent the contents on agriculture and rural community were reflected in the textbooks of agriculture highschool. And 262 new education contents formulating positive and exact rural amenity concept were developed and 62 of them were included in textbooks.

  • Major and reckless development which have been continued during the last half century, have caused decrease and damage of urban green spaces in the point of qualitative and quantitative view. Particularly, it brought about reduction to urban neighborhood park which has taken the main role for landscape ecological value. Recently, neighborhood park planning based on the landscape ecological results has been increasing gradually. Most of all, diverse attempts such as the application of shape character analysis and the step of landscape ecological planning in urban park planning have been proposed. Today, we recognize the importance of comprehensive approach in urban green planning and neighborhood park planning, but landscape ecological approach which is analyzing character and making proposal with isolation, connection and circulation is still insufficient. Most of neighborhood parks in Korea are surrounded by buildings and isolated from adjacent green spaces. Besides, these parks have landscape ecological problems such as reduction of size, isolation from adjacent green spaces, decline of nature, and excessive pavement which we ignored during urban development process. We have sympathy for understanding landscape ecological characters and considering improvement proposals for neighborhood parks Therefore, the purpose of this study was to 1) select five neighborhood parks in Daegu, 2) analyze landscape ecological characters with isolation, connection and circulation, and 3) compare data. It is certain that these results should be the main data for the arrangement of improvement proposals which landscape ecological characters were appled to.

  • This experiment evaluates wintering ability to maintain green color of lawn grasses during winter and investigates the effects of top dressing of fertilizer on improving green color during regrowth. Kentucky blue-grass could maintain green color and leaf chlorophyll content better than tall fescue and creeping bentgrass in winter. All three grasses in this experiment have shown the excellent wintering ability. In enhancing the recovery of green color at the early stage of regrowth, the mulching effect with rice straw was highly significant for creeping bentgrass. Green color recovery in grasses during its regrowth was better at the top dressing plots than at the plots without top dressing, but when fertilizer application levels were increased, green color in lawn grass did not significantly change. Although green color in tall fescue, Kentucky bluegrass, and Korean lawngrass could be maintained during summer, the green color of creeping bentgrass is reduced significantly with high temperature. Top dressing after winter and mowing improved leaf chlorophyll content and green color in tail fescue and Kentucky bluegrass significantly. However, Korean lawngrass did not respond significantly with increased levels of fertilizer.

  • Recently, the call for better accountability and social responsibility from corporations has been regularly voiced, both in the academic literature and in public discussions. This poses a challenge to the existing literature in understanding consumption behaviors to direct them toward sustainable development. This study investigates the purchase intention of Gen Z consumers in Vietnam with green packaging products. Data were collected from 914 respondents by online questionnaire and then analyzed using OLS. The results suggest the significant influence of customers' income and packaging in driving customers' intention to use environmentally-friendly products. Specifically, consumers in a higher income class participate more actively in green purchases. However, problems associated with inadequate packaging are also illustrated, resulting in the poor perception of green messages and poor practice of ecological actions. Besides, subjective norms and green trust are found to be adversely related to green consumer intention. In addition, gender disparity in green behavior is reported, where female consumers show a higher tendency to ecological consumption than their male counterparts. Other demographic factors are also included in the model as control variables, which are age, education, price, environmental literacy, environmental concern, and psychological awareness, but they do not have a significant impact on green purchase intention.

  • China has achieved remarkable economic growth through an extended period of rapid industrialization. However, adverse environmental issues have become more prevalent during this time of development. In particular, car exhaust emissions in the country have become one of the most substantial causes of environmental degradation in China. To combat these issues, the Chinese government is actively implementing green car policies to mitigate the negative environmental concerns. Likewise, Chinese consumers' interest in green cars has also increasing. Despite these changes in consumer perceptions, research on Chinese consumers' green consumption behavior is still in its infancy. Therefore, an empirical study was conducted to measure the relationship between zhongyong(中庸) values, new ecological paradigm(NEP), and green consumption behavior for 334 Chinese consumers. As a result, the study found that the three sub-dimensions of zhongyong(中庸) values(multi-dimensionality, flexibility and compatibility) and NEP had a significantly positive(+) effect on the purchase intention of green cars. It was also found that NEP positively mediates the effect of flexibility and harmony on purchase intention of green cars. This study is expected to provide academic outcomes on China, which is currently the world's fastest growing green car market, as well as providing practical strategic implications for establishing unique green marketing strategy for China.

  • According to the New Town Development Plan, Gang-buk area, a symbol of slum in Seoul will be changed new residential area. There are a lot of challenges for success this project. First of all, new ways of city plan "pre-plan and development" and "environmentally friendly development" are necessary to carry out this plan. Another important idea is how to overcome conflicts such as unbalanced development, a traffic jam and environment problem. Also, Government and a citizen agree that this project have to accept eco-protectable and sustainable development theory. For increasing green area ratio and keeping eco-diversity, planting at roofs and water circulation system in residential complex are compulsory. Green network based on environmentally friendly development provides a natural energe stream on eco-system and protects a city from air pollution, hot air island phenomenon and a flood.

  • Green frame technology intended to facilitate the remodeling of apartment housing complexes in Korea and extend their service life has been developed. Green frame design is a Rahmen structure using composite precast concrete members and, unlike a bearing-wall structure, lifting and installing structural members accounts for major steps of structural construction. Therefore, if green frame structure construction is to be scheduled appropriately, systematic lifting plan needs to be developed in advance. Development of lifting plan also requires unit lifting process of composite PC members (columns and beams) that consist of green frame to be analyzed first. Therefore, this study attempts to analyze the lifting process of composite PC members used in green frame structure. To that end, lifting procedure and time of composite PC column and beam are estimated and applied to a project case to analyze the lifting cycle of reference floor. Outcomes produced herein will be used as key data for development of lifting plan in subsequent green frame structure construction.
