The purpose of the study is to review current status of green roof technology and to suggest the issues and solutions related with the technological problems of green roof in Korea. The scope of the study is limited to the extensive green roof which requires low maintenance. Technological issues related with green roof include soil, water proofing, water drain, vegetation and maintenance. Several solutions to invigorate green roof technology were suggested as follows; 1)implementation of technical standard for green roof and technology certification system, 2) development of suitable raw materials for green roof, 3) construction guidelines and uniform construction specification, 4) formulation of city ordinance for green roof, and 5) exchange program with foreign green roof organizations.

The impermeable area on the surface of city has been increased as buildings and artificial landcover have continually been increased. Urban development has gradually decreased the green zone in downtown and alienated the city from the natural environment on outskirt area devastating the natural eco system. There arise the environmental problems peculiar to city including urban heat island phenomenon, urban flood, air pollution and urban desertification. As one of urban plans to solve such problems, green roof system is attracting attentions. The purpose of this study was to investigate the heat reduction effect according to the development of green roof system and to quantify the heat reduction effect by analyzing through simulation the heat environment before and after green roof system. For thermal environment analysis, Thermo-Render 3.0 was used that was developed by Tokyo Industrial College to simulate. The simulation showed that the heat island index before and after the development of tree-planting on rooftop changed maximum $0.86^{\circ}C$ and the surface temperature changed about $20^{\circ}C$. Only with lawn planting, heat reduction effect was great and it means that the green roof system in low-management-light-weight type is enough to see effect. The simulation identified that only lawn planting for green rooftop brought such difference and could lower the heat island index at a narrow area. It is judged that application of green roof system to wider areas might relieve urban heat island phenomenon positively.

저자는 기후변화에 대응한 저탄소 녹색수변도시 조성을 위한 방향설정을 위해 해외 저탄소 녹색수변도시에 대한 사례를 검토하였다. 해외 저탄소 녹색수변도시 검토 결과 자원순환을 통한 에너지 절감, 시설 및 공간 집약적 토지이용계획, 대중교통 및 보행자 중심의 교통체계, 신재생에너지의 활용을 통한 에너지 저감 및 재활용이라는 시사점을 도출하였다. 이러한 시사점을 바탕으로 우리나라 수변도시에 적용을 위한 방향으로 (1) 교통부문의 에너지 절약을 위한 압축형 도시공간구조, 복합토지이용, 대중교통 중심의 교통제계 계획, (2) 건물 및 일상생활에서의 신재생에너지 활용, (3) 탄소 흡수원 역할과 삶의 질을 높여주는 녹지공간 확보, (4) 물자원의 선순환구조 구축을 제시하였다. 마지막으로 우리나라에서 녹색수변도시 조성을 위해서는 이러한 노력들과 더불어 다양한 해외사례 검토와 기술부문에 대한 조사를 통해 저탄소 녹색수변도시 조성을 위한 기반이 마련되어야 할 것임을 논하였다.

We achieved a highly efficient green OLED with an efficiency of 30cd/A by using a new electron transport material and optimizing the device structure. The luminous efficiency was 16.8lm/W at $3000cd/m^2$ and the lifetime was over 60,000hr at an initial luminance of $1000cd/m^2$. Furthermore, we obtained a threecomponent RGB white OLED by using the highly efficient green material. This RGB white OLED shows more excellent color reproducibility for full color displays with color filters, compared to a twocomponent white OLED.

Purpose - This paper aims to examine the environmental effects of South Korean foreign trade, and the changing relationship between industrial "three wastes" emissions and foreign trade. Design/methodology - Based on time series data of South Korean foreign trade and industrial "three wastes" from 2009 to 2019, a VAR model was used to analyze the long-term internal links and dynamic changes between foreign trade and environmental pollution. Findings - Variance decomposition analysis shows that for the three types of pollutants, self-impact contributes the most to the variance decomposition. It follows that South Korean foreign trade has a certain negative impact on the environment, and this impact has a certain sustainability. Originality/value - This paper contributes to the study on the relationship between foreign trade and environmental pollution. It theoretically proposes a coordinated development path for foreign trade development and green development based on the environmental impact of foreign trade, to provide a reference for the development of collaborative promotion.

The purposes of this research are to estimate area of greenable roof and to monitor maintaining of green roofs using World-View 2 images. The contents of this research are development of World-View 2 application technologies for estimation of green roof area and development of monitoring and maintaining of green roofs using World-View 2 images. The available green roof areas in Gwangjin-gu Seoul, a case for this study, were estimated using digital maps and World-View 2 images. The available green roof area is approximately 12.17% ($2,153,700m^2$) of the total area, and the roof vegetation accounts for 0.46% ($80,660m^2$) of the total area. For verification of the extracted roof vegetation, Vworld 3D Desktop map service was applied. The study results may be used as a decision-making tool by the government and local governments in determining the feasibility of green roof projects. In addition, the project implementer may periodically monitor to see whether roof greening has maintained for efficient management of projects, and a vast amount of World-View 2 images may be regularly used before and after the projects to contribute to sharing of satellite images information.

The need for this study must be considerable, as being activate of green roofs research that the organization and construction obtain access to more development technologies. Nevertheless, the green roofs system has begun to apply since 1980's, the green roofs technology was restricted to develop without verification of technologies such as a load or water leakage. There is a limit as urethane waterproofing to almost domestic waterproofing materials and methods of construction for general green roofs. The introduction of materials and methods of construction which are appropriated to property of green roofs could be a decisive factor in a long-range durability and economical maintenance cost, moreover, it support to variety construction system and organization. This present paper describes a necessity of waterproofing and root barrier system is one of the sub-organization based on green roofs construction, which have enormously large impact on the durability.

본 연구는 주택시장 모형을 이용하여 그린벨트 축소의 경제적 효과를 분석하였다. 그린벨트는 개발이 제한된 토지의 한 종류로 소비자 후생에 영향을 미치게 된다. 그린벨트는 토지의 개발을 제한함에 따라 주택의 공급에 영향을 미치게 되며, 또 다른 한편으로는 주거환경에 녹지를 공급해 줌으로써 주거환경을 개선하는 효과가 있다. 따라서 그린벨트의 축소는 주택시장의 공급을 증가시켜 임대료의 하락을 일으켜 소비자의 후생을 증가시킬 것으로 예상되는 반면 녹지를 파괴함으로써 주거환경을 악화시켜 소비자의 후생을 감소시킬 것으로 예상된다. 따라서 그린벨트의 축소로 인한 임대료의 하락 효과가 녹지파괴로 인한 주거환경 악화 효과보다 클 경우 소비자의 후생을 증가할 수 있다. 본 연구에서는 임대료 하락의 효과가 보다 직접적으로 나타나 주거환경 악화 효과보다 커서 그린벨트 해제로 인해 소비자의 후생은 증가하였다.

The purpose of this study was to examine the purchase behaviors of those who are consistently using Green cosmetics. k order to identify this purpose, this study compared the consumer characteristics among on-going users of green cosmetics, temporary users, and those who have never used the green cosmetics. Also, this study compared the decision making process between on-going users and temporary users. The data were obtained from a questionnaire completed by women who lived in Seoul (N=362), and were analyzed by t-tests, chi-square test, and ANOVA. The findings of this study are as follows: First, unmarried women aged in 20s and those who have higher education, higher incomes and their own houses were more likely to use Green cosmetics consistently. Second, those who were more interested in environmental problems were more likely to be on-going users of Green cosmetics. Third, those who in on-going group were more likely than temporary group to make internal search, while temporary group was more likely to depend on information obtained from their friends or relatives. Also, on-going group considered alternative criteria more than do temporary group.
