  • As is the case in Korea, the expansion of renewable energy dissemination is an essential matter in Ukraine when considering its energy consumption and dependence on energy import. While Korea has set about promoting the new and renewable energy industry on the back of the national policy on green growth, Ukraine expects a virtuous circle of renewable energy industry with green tariffs and the attraction of foreign capital in association with carbon emission trade. Utilizing its well-developed heavy industrial sector including the shipbuilding and automobile industries, Korea expects wind turbine manufacturing to become one of its next-generation growth engines. Ukraine is also trying to enter the wind turbine system or parts manufacturing industry based on its automobile industry and advanced aerospace technology. Although the Crimean region in Ukraine seems to have excellent wind resources, and thus shows great potential as a location for wind farm development, political instability has been a major obstacle to the attraction of foreign capital, leading to delayed investment.

  • Green frame is combined by structural steel and reinforcements of Green column and beam and unified by cast-in-place concrete. However, when upper reinforcements penetrate structural steel hole, the execution is difficult due to interference of joint and a rib of deformed reinforcements. Therefore, the objective of this study is to propose the reinforcement tools to improve productivity of precast structure connection construction. The reinforcement tools proposed in this study can be helpful to improve constructability, safety, duration, and cost comparing with conventional reinforcement method since unskilled workers can deal with reinforcements easily.

  • The precast concrete column-beam structure, Green Frame, allows the main structural members such as precast concrete column and beam to be produced on the site, resulting in a reduction of transportation cost and the margin of plant. However, existing plywood from for in-situ production of precast concrete members has problems like putting in inordinate human resource, falling-off in quality and workability. To solve those problems, form system for in-situ production of precast concrete members shall be developed. In this regard, this study aims to analyze the structural concept of from system for in-situ production. The result of this study will use for development of form system for in-situ production.

  • Antioxidant activity or green tea extracts (GTE) was evaluated in soybean oil (SBO), rice bran oil (RBO) and winterized rice bran oil (WRBO) stored at 63$^{\circ}C$ for 36 days. Lipid oxidation of the oils was determined using the active oxygen method (AOM), peroxide value (POV), change in unsaturated free fatty acid concentrations and by sensory evaluation. SBO had a higher concentration of the polyunsaturated fatty acids, linoleic and linolenic acid than RBO and WRBO. WRBO and RBO were more stable against lipid oxidation than SBO. Addition of GTE (200 ppm) to the stored oils, increased the induction period (IP) in AOM, reduced the increase in POV, and lessened the change in unsaturated fatty acids. Furthermore, GTE prevented the development of rancid flavors resulting from storage, all of which demonstrate the protective antioxidative activity of GTE. However, oil color became darker in the GTE treated oils. The antioxidant protection of GTE was most effective in RBO.

  • The purpose of this study is to investigate city residents' attitudes and cognition of Daegu City toward Green Tourism. A Questionnaire survey was conducted in september, 2006. The sum of 515 copies was analyzed. City residents recognized the problems of leisure activities as 'burden of expense', 'lack of program diversity' and the advantages of this as 'withdrawal of stress and increase of vitality', 'promotion of health for themselves and their family'. Among theme experiential activities, they preferred 'health/leports experience' 'traditional food experience', 'traditional culture experience', 'nature-ecological experience', respectively. By the result of cross-table analysis, there are many differences between groups by gender & age. Therefore, further development of specific experiencing activity programs and marketing techniques, are required.

  • This study aims to suggest an evaluation methodology of green-tourism potential for village level with amenity resources in rural areas. The amenity resources system was classified into three sub-classes(social, industrial, and natural/cultural/historical resources) and a relationship diagram between three classes and tourists' behavior was also defined. The methodology considers human resources in the village including the three sub-class amenity resources. The table and diagram were applied to make renewal plan for rural villages of the study area, Nami-myun, Keumsan-gun, Chungnam province, so that the development scheme for the villages was suggested reasonably by the new findings of this study.

  • Pinus $rigida{\times}taeda$ and Liriodendron tulipifira have been planted in this country for about 20 years. They are known as a relatively 13st-grown and useful species. The physical properties such as green moisture contents, specific gravities and dimensional shrinkages were examined with natively grown timbers. The kiln-dry schedules were developed with 30m thick boards by using an oven-fast-drying method. In both species the green MC's of sapwoods were higher than those of heartwoods, but their discrepancies were small. The green specific gravities of Pinus $rigida{\times}taeda$ and Liriodendron tulipifera were 0.48 and 0.41~O.42, respectively. The developed kiln-dry schedules were proven to minimize drying defects for the hoards of 30mm thickness and various width.

  • High efficiency white organic light emitting diodes were fabricated by using an alignment free mask patterning method. Only red/green emission without any blue emission was observed in the red/green patterned region and blue emission was emitted in other area. A combination of the red/green and blue emission gave a high efficiency white emission. A maximum current efficiency of 30.7 cd/A and a current efficiency of 25.9 cd/A at 1000 cd/$m^2$ were obtained with a color coordinate of (0.38, 0.45).

  • Green Standard for Energy and Environmental Design(G-SEED) has been implemented for the realization of sustainable development and resource-saving and eco-friendly buildings from 2002. Studies about the green buildings are made actively and is being developed through constant revision. However, study results of green building have not been fully reflected in the standard. Therefore, this study analyzes the previous studies about G-SEED for school facilities and check the degree of to reflect the problems and improvements suggested in previous studies. This study will be a reference of future revision Substantial problems and requirements are not reflected in revision standard. Proposed improvement requirements are classed as to improve the items(establish specific standards, supplementation), strengthen standards(designate the prerequisite items), propose a new evaluation method, add new items. delete exist items and adjust the score. Therefore, future revision of G-SEED for school facilities should reflect the results of previous studies.
