  • 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.

  • To achieve the "low carbon green growth" vision, the first step is securing core technologies. Therefore, S&T policy direction for green technology development is urgently needed. As of 2008, investment in green technology (GT) development hovered around 10% of the government's total R&D budget. Thus, the Korean government developed a plan to increase that percentage to 15%, by 2013. To develop reasonable investment strategies for green technology development, targeted strategies that reflect technology and market changes by green technology area are needed. However, the overall planning and coordination of national GT development is currently split among, approximately, 10 government ministries. To establish an efficient green technology development system, the so-called "Green Technology R&D Council" should be launched in collaboration with the Presidential Committee on Green Growth and the National Science and Technology Council. Furthermore, to build a solid foundation for commercializing the outcomes of GT development projects and promote GT transfer, the government should undertake two initiatives. First, the government should reinforce GT R&D performance management, by establishing a GT R&D performance management and evaluation system. Second, the government should implement the "customized packaged support for promoting green technology business rights and commercialization" and present "e-marketplace for market-oriented green technologies". Creating a pan-ministerial policy for GT development policy would necessitate restructuring the HR(Human Resources) development system, which is currently separated by technology area. Based upon mid/long-term HR supply and demand forecasts, the government should design differentiated HR development projects, continuously evaluate those projects, and reflect the evaluation results in future policy development. Finally, to create new GT-related industries, the "Green TCS (Testing, Certification, and Standards) System" needs to be implemented. For objective evaluation and diffusion of R&D results by green technology area, a common standardization plan for testing, analysis, and measurement, like the "Green TCS", should be developed and integrated.

  • Green technology encompasses a growing group of methods and materials, from techniques for generating energy and alternative resources to non-toxic cleaning products. Green technology is expected to solve current problems in atmospheric environment such as climate changes due to green house gases and hazardous air pollutants. This paper provides a review on the status of green technology and policy guidelines in Korea as well as the green technology for air pollutants. It presents the R&D projects and future direction in atmospheric environment, and the green technology in mobile source air pollution. Emerging green technology contributes to sustainable growth and development of atmospheric environmental industry for better air quality.

  • This paper proposes an R&D project selection methodology for green technology centered on developing country-oriented technology commercialization. Eight selection criteria are derived from the R&BD logic model : technology needs of developing countries, effectiveness of green technology, technological potentials, domestic technological capability, commercialization feasibility, economic benefits, business feasibility, and spillover effects of developing countries. 21 qualitative and quantitative indicators are then defined for each criterion. The analytic hierarchy process is conducted to produce relative importance of evaluation indicators and to set final priority scores of R&D project candidates. The working of the proposed methodology is provided with the help of a case study example of Green Technology Center. The proposed methodology is expected to be effectively utilized for policy practices of R&D project selection in the field of green technology.

  • The necessity for harmonically growing of economy and environment has been on the rise late in the twentieth century. Green transformation is defined as efficiency enhancement of conventional guns and ammunitions. We also define green innovation as evolution of fire power systems breaking with conventional methodology. This kind of green innovation could even change a paradigm of warfare in the future. In this paper, we classify the green technology in the field of fire power into five technological groups, and the research and development trend of green technology in the field of fire power is analyzed.

  • A modified sugarcane bagasse (SCB) fixed bed column was used to remove $Pb^{2+}$ from aqueous solution. To determine the optimal condition for $Pb^{2+}$ separation, $Ca^{2+}$ was chosen as the model interfering ion, and effects of $Ca^{2+}$ and $Pb^{2+}$ initial concentration ratio ($C_0^{Ca}:C_0^{Pb}$) on theadsorption of $Pb^{2+}$ were investigated. Results showed that adsorption amount ratio of $Ca^{2+}$ and $Pb^{2+}$ ($q_e^{Ca}:q_e^{Pb}$) had a good linear relationship with $C_0^{Ca} :C_0^{Pb}$. Mass ratio of $Pb^{2+}$ absorbed on the modified SCB was higher than 95% at $C_0^{Ca}:C_0^{Pb}$ <1.95, illustrating that $Pb^{2+}$ could be selectively removed from aqueous solution. To verify that, simulated waste water containing co-ions of $K^+$, $Na^+$, $Cd^{2+}$ and $Ca^{2+}$ was treated, and results showed that the equilibrium amount of $Pb^{2+}$, $K^+$, $Na^+$, $Cd^{2+}$ and $Ca^{2+}$ adsorbed was 134.14, 0.083, 0.058, 1.28, and $1.28mg\;g^{-1}$, respectively, demonstrating that the modified SCB could be used to remove $Pb^{2+}$ from aqueous solution in the investigated range.

  • The purpose of this study was to development of the green information technology practical method and verify the impact of classes which applied green information technology practical method on the students' practice on green information technology to enhance the study related to green growth education for Technology Home Economics Education. In order to achieve the purpose, first, the green information technology practical method and measurement instrument were developed. Second, green information technology practical method applied in class. Third, D middle school students(male 62, female 59) in Daejeon city were tested by green information technology practical method measurement instrument and the comparison between pretest and posttest results were made. There were three results conduced from this study. First, green information technology practical method had positive impact on the students' green information technology practice on the items which they directly face in their daily lives, such as computers, monitors, and data. Through this point, when green growth curriculum developed in Technology Home Economics, we must consider the more closely related in lives contents. Second, green information technology practical method not impact on the practice on the items such as printers, peripherals, and other items. But in the future we expect more students hold printers and peripherals so the study for these items needed the more. Third, there were no gender differences in green information technology practice. Through this point, when green growth curriculum organized, there was no needed to separete students' gender.
