This study was conducted to investigate residual organochlorine pesticides in green house soil and green perilla leaves. Extraction and clean-up method were developed using the modified QuEChERS method for residual organochlorine pesticides (ROCPs) in soil and green perilla leaves. Recovery and limit of quantitation (LOQ) of ROCPs in greenhouse soil and green perilla leaves were 76.3-113.4 and 79.4-107.3%, 0.03-0.24 and $0.33-0.50{\mu}g/kg$, respectively. Detected ROCPs in greenhouse soil were dieldrin and endosulfan sulfate, the residue were 1.6-9.2 and $22.0-87.8{\mu}g/kg$, respectively. But two pesticides in all green perilla leaf samples were not detected. These results showed that ROCPs residue in greenhouse soil was lower than the level of bioaccumulation occurring.

Study was conducted to investigate the optimum amount of nitrogen fertilizer for the green forage production of Italian ryegrass at the paddy field after rice harvesting in southern part of Korea in 1987 and 1988. Effects of three levels of nitrogen fertilizer application (15, 30 and 45 kg N/10a) on the green yield and nitrate content of green forage at three cutting times (April 30, May 20 and June 10) were examined in 1988. The results were as follows. 1. Yield of green forage at all cutting times increased in order of 45 > 30 > 15 kg N/10a, and it increased about 14 percent in the 45 kg N/10a and decreased about 35 percent in the 15 kg N/10a compared with the 30 kg N/10a. 2. Nitrate content in the green forage at all cutting times was high with increasing amount of nitrogen fertilizer and with decreasing ratio of K/(Ca+Mg) in green forage. The nitrate content at the second and the third cutting times in the 45 kg N/10a might be outrunned the tentative limitation for cattle. 3. Maximum amount of nitrogen fertilizer was 48 kg/10a for total green forage production, but it was 38 kg/10a near at cattle's harmful limit of nitrate content in green forage.

Being producing and evaluating oat-chocolate were a major goal in this study. There were various steps to make oat-chocolate. First, oat was roasted with an optimum roasting-temperature. Second, discovered the best natural antioxidant to extend storage period and improve quality of goods. Third, developed processing goods and made an evaluation of quality properties. We selected optimum roasting condition of $160^{\circ}C$ for 15 min based on the acid value and the sensory characteristics such as color, taste, smell and overall preference of oat flour. As for natural antioxidants, we made use of 3 kinds of antioxidants (cactus, lavender and green tea) and two concentrations (0.5 and 1%). In investigating antioxidants, an acid value was significantly decreased as the antioxidants were added (p<0.05). Nothing was as low in acid value as a chocolate with 1 % lavender flour in 7 days. Findings showed the sensory characteristics of products containing antioxidants such as green tea and cactus, were higher than those of Cont. in 7 days. A product including 0.5% green tea marked the best sensory score among antioxidants. Compared cost among 3 antioxidants, green tea was the cheapest. In the end, 0.5% green tea was selected as an optimal antioxidant to make high-quality oat chocolate. We made an end product by mixing green tea (0.5%) and oat. With respect to Hunter's color L (whiteness), a (redness) and b (yellowness), as green tea added, L and a level showed an increasing tendency. However, an opposition result was expressed in b level. When compared pH value and total acidity, it was statistically identical between Cont. and product with 0.5% green tea (G-0.5). There was different acid value among specimens. The acid value of G-0.5 was lower than that of Cont. up to 7 days, resulting in lower acid value than a ready-made product (D-Co.). When we assessed the sensory characteristics, G-0.5 was higher than other specimens such as Cont. and ready-made products (D-Co. and H-Co.) up to 6 days after manufacture. Put previous findings together, the addition of 0.5% green tea increased an antioxidative effect as well as the sensory acceptability of oat-chocolate.

This study focused on cases that led sustainable urban development through the construction and utilization of organic greenery systems linking green spaces of urban peripheries with metropolitan areas. To that end, Berlin - Brandenburg's regional parks in Germany and Milan's Raggi Verdi, a radial green axis project, in Italy were selected for analysis as case studies. As frameworks for this analysis, this study has established existing infrastructure accessibility and linkage, recycling and cooperative management. The results of the case study analysis are as follows: First, the specialized spatial strategy based on the individuality of the green space outside the city rather than a uniform landscape was used as the foundation of the sustainable development plan. Second, physical linkage from the center of the city to the periphery contributed to the sustainable development of the overall metropolis by improving the economic value of the surrounding area as well as ecological and environmental values. Third, the central management system was established to reduce the administrative inconvenience caused by multiple administrative districts in the green space of urban periphery. The implications of applying the above results to Seoul, Korea are as follows. First, it is necessary to establish a differentiation strategy by re-establishing the identity of a green landscape in the urban periphery, because the green spaces of Seoul's periphery are dispersed and mostly have a repetitious mountain landscape. Also, it is necessary to actively link peripheral mountains and urban green areas to create ecological value and economic value, and ultimately to help the sustainable development of the city. Finally, building an integrated management system is required to solve fragmented green space management departments in most of the urban periphery's green spaces. In conclusion, this study shows the significant possibility that the sustainable development of a metropolis can be derived from the utilization, linkage, and management of the green space in the urban peripheries, which is extraordinary compared to normal centralized urban development.

The purpose of this paper is the development of measurement algorithm for green-sheet based on the digital image processing technique. The Low Temperature Cofired Ceramic (LTCC) technology can be defined as a way to produce multilayer circuits with the help of single tapes, which are used to apply conductive, dielectric and / or resistive pastes on. These single green-sheets have to be laminated together and fired in one step all. Main functionality of the green-sheet film measurement algorithm is to measure the position and size of the punching hole in each single layer. The line scan camera coupled with motorized X-Y stage is used for developing the algorithm. In order to measure the entire film area using several scanning steps, the overlapping method is used. In the process of development of the algorithm based on the image processing and analysis, strong background technology and know-how have been accumulated.

The Republic of Kazakhstan is a geographically large but sparsely populated country, rich in natural resources, located in the center of the Eurasian continent. In recent years, it has begun to create a green economy, leading it among its neighbors in Central Asia. Therefore, the country has set a clear goal: by 2030, emissions should be reduced by 15-25% compared to the level of the 90s. As part of the country green economy strategy, in 2013 Kazakhstan adopted the "National Concept for the Transition to the Green Economy until 2050", which sets out the principles of the green economy as a path for future development. The goal is to bring the share of renewable energy in electricity production from zero to 3% by 2020, and then increase it to 30% by 2030 and 50% by 2050. This paper looks at what Kazakhstan has done to promote renewable energy and provider perspectives. The paper also considers Kazakhstani legislation in terms of the development of renewable energy sources and provides information on incentives and preferences for the development of renewable energy sources. Thus, it will be easier for investors to evaluate the implementation of potential projects in Kazakhstan.

While deforestation and forest degradation has continued globally, global society has been making efforts to prevent deforestation towards sustainable development. Reforestation in developing countries is linked to Sustainable Development Goals (SDGs) such as climate change mitigation, conservation of biodiversity, eradication of poverty and upholding of human rights. Forest official development assistance (ODA) restores the global forest land, and increases the public benefit. Bilateral forest ODA projects of the Republic of Korea have gradually increased and most of those projects have currently been concentrated in Asian countries. Selecting recipient countries for forest ODA requires more comprehensive approach since the global goals for sustainable development has been widely adapted to ODA strategic plans. We proposed potentially promising countries that are eligible for receiving 'Green ODA' in perspective of economic, social and environment to implement reducing emissions from deforestation and degradation (REDD+), conserving biodiversity, and combating desertification. As a result, the study suggests that forestry cooperation could be expanded from Asian countries more toward South America and African countries. In addition, we emphasized the need to promote convergence and integration with green technology to fundamentally solve the negative impacts of deforestation such as food, energy, water resource shortages, and forest fires. We advocated expanding bilateral ODA in the forestry sector through diversification of project activities, financial sources, and participants. Our study can contribute to the provision of basic information for establishing long-term strategies to expand bilateral cooperation in the forestry sector.

Recently, issues on the environment, which have become key bottlenecks relative to sustainable economic development, have generated common concern. However, relatively scant research has been devoted to consideration of relations between consumers' environmental concern, green fashion advertisement value, and green consumption. In this study, using structural equation modeling (SEM), effects of environmental concern, perceived green fashion advertisement value, and attitude towards green fashion advertisements, on ecological purchases and their interrelationships are investigated. A model is constructed to link aforementioned constructs. Data, was collected through a questionnaire-based online survey (www.sojump.com) of 260 Korean consumers and 260 Chinese consumers. Findings suggest that environmental concern can improve their perception of green advertisement value. One of the findings showed strong positive relationship among green advertisement value, positive attitude, and purchase intention towards green fashion advertisement, while environmental concern negatively influenced their attitude towards green fashion advertisements. It suggests that if companies adopt green advertising strategies, environmentally-conscious consumers are willing to pay more, to purchase green fashion goods in to satisfy their needs. We should put more effort in educating consumers about environmental issues, to raise the level of environmental awareness and satisfy their concerns relative to green fashion goods. Conversely, there is significant positive relationship with the moderating effect of consumers' nationality in all paths, so results above would make significant contributions to green literature, and would also contribute to advertisement strategy implications as well. Especially fashion marketers, an use accurate and fair environmental claims in their advertisements to increase sale and profits.
