  • In this study, we predict the generation of end-of-life photovoltaic modules when Feed in Tariff applied, in Republic of Korea. Based on the installation of photovoltaic modules, we prepared three different senarios in order to estimate the generation of end-of-life photovoltaic modules. The senarios are i) early worn-out, ii) mid worn-out and iii) late-worn out senario. We selected the mid worn-out senario to estimated the amount of end-of-life photovoltaic modules in this study. Establishment of the end-of-life module generation scenario predicted generation of end-of-life photovoltaic module, and forecasted generation amount of end-of-life module to which Feed in Tariff was applied in consideration of installed photovoltaic modules installed by Feed in Tariff support. The generation of Feed in Tariff-applied end-of-life modules increased from 2021 to 2025 compared to without Feed in Tariff, and since then, the Feed in Tariff-applied end-of-life modules were generated as waste modules during the relevant period (2021 ~ 2025).

  • The purpose of this research was to elucidate the relevance of the area of home economics in practical arts (technology & home economics) curriculum to green growth education, finding applicable cases of green growth education content in the field of home economics education. Given this base, we performed a survey with people who majored in home economics education and elementary school teachers on how green growth education related to their education. We studied applied cases and performed a survey by open-ended questions that extracts the green growth education content. In synthesizing the results of these studies so far, we have concluded that home economics education is much related to green growth education, and that with a change of people's conceptions when relating school life to household life, home economics can be a very useful subject that can lead to the practice of the green growth education.

  • Pythium ultimum에 의하여 발생하는 오이 모잘록병의 생물학적 방제의 효율을 연구하기 위하여 여러 미생물 제제인 Trichoderma harzianum, Streptomyces sp., Bacillus sp.,(그린바이오텍, 경기도 파주)에 톱밥, 쌀겨 등이 첨가되었다. 감자한천배지에 첨가한 톱밥 자체만으로도 P. ultimum 균사의 생육이 저해되었다. Green-all T(Trichoderma harzianum), Green-all S(Streptomyces), Green-all G(Bacillus)제제들은 오이 모잘록병의 발생을 현저히 감소시켰다. 그러나, 종자를 파종하고 병원균을 접종한 실험에 있어서 톱밥, 쌀겨 등을 Green-all T, Green-all S 제제에 첨가한 것은 입모율에 있어서 미생물 제제 단독처리에 비하여 생물학적 방제의 효과가 현저히 증가하지는 못하였다. 대조적으로, Green-all G 제제는 아미노닥터를 첨가하여 주면, 단독 처리시의 42% 이병율에서 2% 이병율로 크게 감소하여, 오이모잘록병에 대한 오이묘에 대한 생물학적 방제효과 실험에서 Green-all T 제제에 톱밥을 첨가하면, 발병도(disease index)가 56으로 5로 감소하여, P. ultimum의 생물학적 방제 효과가 톱밥이 첨가되지 않는 것에 비하여 더욱 증가되었다. 이는 유기물 첨가에 의하여 생물하걱 방제 효과가 증진될 수 있음을 가르쳐 주는 것이라 하겠다.

  • Browning of tea infusion is an obstructive factor influencing shelf life of ready-to-drink green tea. Effects of temperature and illumination on the browning of green tea infusion were investigated. It was shown that both elevated temperature and illumination led to the browning of green tea infusion, but temperature had greater effect on infusion color and level of catechins than illumination. The levels of unoxidized catechins such as (-)-epigallocatechin gallate (EGCg), (-)-epigallocatechin (EGC), (-)-epicatechin gallate (ECg), (-)-epicatechin (EC), and total catechins remaining in the tea infusion were significantly correlated to color parameters of the tea infusion. Sodium ascorbate inhibited the infusion browning by suppressing the oxidation of tea catechins and it is considered to be a more suitable preservative for prolonging shelf life of ready-to-drink green tea than ascorbic acid because it has less effect on tea taste. The effects of temperature and illumination on the epimerization of catechins were also discussed.

  • There are $10{\sim}30%$ polyphenol and $2{\sim}4%$ caffeine in green tea. Caffeine is a kind of alkaloid containing nitrogen which cause stimulation, impatience, headache, insomnia, low birth weight infant. Because of these negative effect, decaffeined beverage came out and decaffeined coffee already have a big market since 1970s. Having proving the physiologic functions of green tea, high consumption of coffee is shifting to green tea. Because of the carcinogenic effect of the organic solvents, decaffeine processing with supercritical carbon dioxide has industrialized and have an advantage in environment-friendly and minimized flavor loss. Decaffeined green tea using supercritical carbon dioxide is considered to be safe but there are not enough study. We investigated the chromosome aberration test with mammalian cell line, CHL. When the cells were treated with 5000, 2000, 1000 ${\mu}g/ml$ and compared with the negative controls, there were no significant(P>0.05) increased chromosome aberration. Same results was observed when adding S9 mixture or not. As a result, water extract of decaffeined green tea using supercritical carbon dioxide does not induce chromosome aberration.

  • The tremendous growth of population and physical development in the largest urban agglomeration in Indonesia -the Jakarta Metropolitan Region, also known as Jabotabek (Jakarta, Bogor, Tanggerang, Bekasi)- has created many environmental problems, such as land use conversion, increasing urban temperature, water and air pollution, intrusion of seawater, and flooding. These problems have become more serious as the urban green space (trees, shrubs, and groundcovers) has decreased rapidly with the urbanization process. Urban green space directly benefits the urban environment through ameliorating air pollution, controlling temperature, contributing to the balance of the hydrological system, and providing space for recreation and relaxation. Because there is little hard data to support the claim of decreasing greenery in Jabotabek, it is necessary to measure the amount of urban green space. The paper describes the spatial analysis of urban green space within Jabotabek through the use of a geographical information system (GIS). We used GIS and remote sensing to determine land cover change and predicted greenery percentage. Interpretation of Landsat data for 1972, 1983, 1990, and 1997 showed that Jabotabek has experiences rapid development and associated depletion of green open space. The proportion of green open space fell by 23% from 1972 to 1997. We found a low percentage of urban green space in the center of Jakarta but a high percentage in fringe area. The amount of greenery is predicted by the Ratio Vegetation Index (RVI) model: predicted greenery (%) = [146.04] RVI - 134.96. We consider that our result will be useful for landscape planning to improve the environment of Jabotabek.

  • 이 연구의 목적은 한국과 일본의 고등학교 가정 교과서에 실린 녹색생활교육 학습자료 내용을 분석하는데 있다. 2007 개정 교육과정에 근거한 고등학교 l학년 기술 가정교과서 6권과 일본의 고등학교 교과서 4권을 포함하여 총 10권을 분석하였다. 한국과 일본의 고등학교 가정교과서 분석 결과, 두 나라 모두 녹색생활교육 자료가 가정경영/소비생활 영역에 가장 많고, 학습 자료 유형은 표/그림/사진 자료가 가장 많았다. 한국 가정교과서에는 녹색생활교육 관련 내용과 실천적 활동 학습자료가 전 영역에 거쳐 다양한 형태로 제시되어 있으나 출판사별 차이를 감안할 때 현장교사는 학교에서 채택한 교과서 이외에 다양한 교과서를 참조하는 것이 필요하다. 차기 가정과교육과정에는 선행연구에서 밝힌 녹색생활 내용요소들을 고루 포함하고, 중학교의 학습 자료 내용과 차별하여 심화된 실천적 행동을 유도할 수 있는 내용으로 구성하여야 할 것이다.

  • This study aims to presents Evaluation Method of Green Remodeling that analyze the value of environment through expense, using the method of life cycle cost and life cycle assessment simultaneously. The results of this study are summarized as follows. Evaluation Model developed in this study can convert economical value of environment into cost by integrating. In addition, the model can apply as a useful tool to estimation of economical design alternative as well as quantification of environmental loads and costs. Evaluation Model presented In this study observe energy consumption and the environmental load emission with qualification, it can forecast effect of environmental cost that cost estimation is expected to be added to energy cost rate by being possible. Synthetically, when Estimation Model and computer program that developed in this study is applies to the construction industry; reasonable management of environmental load is convenient at each step of Green Remodeling. In addition, at preliminary design phase, practical use may be possible by reasonable yardstick about various alternatives and improvement of design alternatives likewise by grasping environmental effect.
