The objective of this study was to determine the antioxidant and quality characteristics of yogurt added green olive powder stored at $4^{\circ}C$ for 15 d. The following four groups were used in this study: Control group (GY0), Yogurt added with 1% green olive (GY1), with 3% green olive (GY3), and with 5% green olive (GY5). The more time of titratable acidity went by, the more it increased. Except GY0, viscosity tended to decrease in other groups (p>0.05), and the more time of syneresis went by, the more it increased, but GY3 of them showed the lowest syneresis. Lactic acid bacteria showed no significant with GY0 until 5 d, but after that, GY1, GY3 and GY5 showed lower than GY0. Yogurt added green olive showed darker color than GY0 (low $L^*$ and high $a^*$). The antioxidant activity of GY5 was found to be the highest among the four groups at day 1 of storage. Total phenolic content, 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity, and reducing power of GY5 was found to be the highest among the four groups at day 1 of storage which were 6.96 mg GAE/kg, 47.53%, and 0.57, respectively. In the sensory evaluation sweet and overall of GY3 indicated the highest score among the four groups. Results of this study demonstrated that green olive powder might be used to improve the antioxidant capacity and sensory characteristics of yogurt.
At present, monitoring programmes for green network have been mainly based on field sampling, which relies on attributes of an area at one point in time, reflecting an emphasis on the small number of in-situ data. One of the major disadvantages of traditional field monitoring is that it is costly, laborious and time consuming due to the large number of samples required. The aim of this research was to evaluate green network based on pixel of Landsat TM satellite image. An empirical study for a case study site was conducted to demonstrate how a standard remote sensing technology can be used to assist in monitoring the green network based on pixel. The pixel-based analysis made it possible to identify area-wide patterns of green network subject to many different type of artificial structures, which cannot be acquired by traditional field sampling. It was demonstrated that the degradation trends of green network could be used effectively as an indicator to restrict further development of the sites since the quantitative data generated from remote sensing can present area-wide visual evidences by permanent record. It is anticipated that this research output could be used as a valuable reference to support more scientific and objective decision-making in monitoring green network.
This study was carried out to propose improvement planting method by the research and analysis of planting concept, planting density, planting style and pattern in apartment complex, Seoul. Survey sites were selected by reflecting the change of green area ratio : Hawgok Jugong apartment complex, Gangseo-gu(1974), Samik-green apartment complex, Gangdong-gu(1980), Dongsindaea apartment complex, Gangseo-gu(1992). Green area in apartment complex was classified with front green area, side green area, and back-side green area. Planting concept that composed of landscape planting concept but anyother concept was not, was similar to all sites not differ from creation time. And planted species was not differ from planting style. Planting density was of both conopyㆍunder story layer was 0.0∼0.2 tree/$m^2$, and that of shrub layer was 0.0∼0.5 tree/$m^2$ Shrub layer planting density was insufficient and the density was not changed according to the creation time. Canopyㆍunderstory and shrub was planted to another green space, not concern with multi-layer structure. Planting pattern was utilized to single planting, linear planting, and random triangle planting, but it was not to the change that in each green space planting concept. Green area in apartment complex should be variety according to planting density, planting structure and planting pattern. And we should get the function of covering and beauty in case of front green space, that of ecological environment and increasing green volume in case of back-side green area, that of increasing green volume in case of side green area, apartment complex.

The industrialization of central Europe more than 100 ago marked the beginning of densely concentrated buildings in quickly growing cities. A cheap type of roofing material of that time was tar. But it was dangerous because it was high inflammable. Then some roofer had a splendid idea. They used sandy material as a final layer atop the impermeable tar layer. These roofs were much more fire resistant than the typical roofs. In this sandy layer some plant species began to grow spontaneously. This was the beginning of the green roof history of modern Europe. A number of these green roofs survived both world wars. In the early 80's in Berlin alone, 50 such buildings existed and they continued to be waterproof until the present day. Since the 1992 Earth Summit of 1992 in Rio de Janeiro(http://www.johannesburgsummit.org/html/basic_info/unced.html) the term "sustainable development" became of central interest of urban designers. In city regions green roofs had become synonymous with this term. With a small investment, long-lasting roofs can be created. Further back in history, more exciting examples of green roofs can be found. The hanging gardens of antiquity are well-known. There are also green roofs built as insulation against cold and heat all over the world. For over 20 years, roof greening in central Europe has been closely examined for various reasons. Roof greening touches several different disciplines. Of primary interest is the durability of the roofs. But ecologists are also interested in green roofs, for instance in biodiversity research. The beneficial effect of greening on water proofing was also proven. For some time, the issue of fire protection was investigated. According to tests, green roofs received a harsh careful rating. Their fire protective property is considered similar to that of tile roofs. Another recent impulse for the green roof movement in Germany has come from the evident improvement of storm water retention and the reduced burden on the sewer system. The question of whether and how much energy green roofs can save has become an urgent question. The state of the research and also various open questions from a central European point of view will be discussed in the context of international collaboration. Apart from academic considerations, those who involve themselves in this issue take a predominantly positive view of the numerous existing green roofs in Germany. In some cities, green roofs are the typical construction technique for new buildings. A few outstanding examples will conclude this review. In Germany, about 20 companies, some of which operate internationally, specialize in green roof consulting. Learning from each other in an open-ended way with respect to different construction techniques and applications in various climatic regions can only be accomplished through such international collaboration as is taking place here.
The purpose of this study was to examine the best condition for dyeing silk in green color used kudzu-vine leaves which were available everywhere in our country except winter. Dyeing experiments were done under various dyeing conditions according to extracting method of dyebath from kudsu-vine leaves, pH of dyebath, dyeing time, concentration of dyebath and mordants which were treated after dyeing. Color difference ($\Delta$E) and Munsell's HV/C and color fastness to drycleaning, washing, perspiration and light were measured. The main results were as follows : 1. The color difference of dyed silk increased in dyebath B & C which were extracted in alkali water comparing with dyebath A which was extracted in distilled water. In dyebath B & C, the color difference was the highest in case of dyebath pH 5.0. 2. The colors of fabrics dyed in dyebath A were mainly yellow and the colors in dyebath B & C were yellow green. 3. The color differences of dyed silk increased according to dyeing time and concentration of dyebath. 4. The color were changed with the treatment of mordants. The most strong green color could get in Cu mordant treatment in dyebath C, pH 5.0, and concentration 4. 5. The peak of reflectance within the visible light of the fabric dyed in the most strong green color could be seen in $\lambda$500-520nm. 6. On the whole, the colorfastness of experimental fabrics dyed in dyebath B, C and Cu mordant treatment was good except the colorfastness to the light.
In order to use the liquid whole eggs as an ingredients of retorted products, the provention of the green-grey discoloration of retorted liquid whole eggs by the addition of the Na$_2$EDTA was investigated. And palatability change of the retorted liquid whole eggs by the addition of Na$_2$EDTA was also investigated. The results obtained were summarized as follows: 1. More severe green-grey discoloration was occurred when higher cooking temperature and longer cooking time were used. 2. Green-grey discoloration of retorted liquid whole eggs could be prevented by the addition of about 0.015% of Na$_2$EDTA. 3. The palatability of retorted liquid whole eggs was not lowered by the addition of 0.02% of Na$_2$EDTA and green grey discoloration was not developed during the storage time of 22 days at room temperature.
Effects of shaking, medium consistency and anther density on polyhaploid production in two wheat cultivars, Pavon and Chris, were studied using a modified 85D12 medium. Pavon produced more calli in shaking and more albino plants tban Chris. However, Chris produced threefold more green plants than Pavon in non-shaking treatment. More calli and green plants were derived from non-shaking treatment than those from shaking treatment. Anthers were cultured on both liquid and semi-solid 85D12 media, using two anther densities, 48 and 96 anthers per plate. Although Pavon generally produced more calli and albino plants than Chris, Chris produced more green plants than Pavon. More green plants were derived from semi-solid medium than those from liquid medium. A factor that may affect plant regeneration from anthers is the length of time on initiation medium. Most of the calli for both genotypes were transferred during the first two time periods. Fertility, as measured by seed set, was determined for all surviving regenerated plants. About 24% of Chris and Pavon anther-derived green plants in the experiment of medium consistency and anther density produced seed.

The surface-drainage system, which consists of bio-swale and detention-infiltration Basins and carries out the function of temporary detention-infiltration of runoff, is defined as the "natural drainage system". It is an environmentally sound and economically beneficial practice to reduce run-off by retaining it in swales as much as possible and letting run-off infiltrate into the ground. In order to estimate appropriate capacity of swales, it is necessary to know how long will it take for certain depths of water to infiltrate. The ponding times, or infiltration times, of various depths and of various soil textures, could be estimated with the Green-Ampt Infiltration Model. Included soil textures are loamy sand, sandy loam, loam, silty loam, sandy clay loam and clay loam. Ponding depths are from 10cm to 100cm intervals. Newton-Raphson method is used for the solution of the Green-Ampt equation by a computer program. The computer program was written with the FORTRAN Developer 4.0 v.. Selected ponding depth is acceptable when the sum of the ponding time and the breeding time of mosquitoes is less than the tolerance period of innundation of grasses and trees.and trees.

This study compared the effect of green light consequent on maximum brightness 85 lx and intial brightness 15 lx, and its accompanying psychological, physiological response. 1) As a result of psychology(general stress evaluation, Symptom Checklist-90-Revision) evaluation, all stress evaluation items mostly showed a decrease, and they are comparatively positively evaluated in minimum brightness 15 lx comparing to maximum brightness 85 lx. 2) Physiological (Heart Rate Variability) evaluation result was included in stable range in all cardiovascular system variables after light stimulus in time of comparison with the standard range; in addition, the Heart Rate Variability evaluation result was found to be stable in all cardiovascular system variables except Low Frequency in minimum brightness 15 lx comparing to maximum brightness 85 lx. 3) Green light was found not to appear as a stimulating factor in the human body in time of space projection, being found to be effective in stability of mind and body, and reduction in stress. Thus, it was found that green light functioned as an emotional, relaxing tranquilizer by working on the sympathetic nervous system.
This experiment was conducted to investigate the effects of a growth retardant uniconazole treatment time on the growth and flowering of Cymbidium Pine Clash 'Moon Venus' and Cym. Green Sour 'A One' in order to develop a substitutional technique on the highland cultivation. Leaf growth of both cultivars was more remarkably reduced by earlier uniconazole treatment time and growth reduction of 'A One' was more remarkable than 'Moon Venus'. Flowering time of 'Moon Venus' treated with uniconazole at May 7 and 27 was accelerated by 5 and 6 days respectively. Moreover, the number of inflorescences and florets showed a tendency to increase. However there was no difference in flowering time of 'A One' among treatments but there was a tendency to decrease in the number of inflorescences and florets by uniconazole treatment. In both cultivars, there was no difference among treatments in the length and width of lower sepal which represent the floret size.
