This paper offers a landscape design proposal for the 2014 Dreampark Chrysanthemum Festival within the Sudokwon Landfill Site. This site is located at 58 Baeksukdong, Seo-gu, Incheon, and it has an area of approximately $560,000m^2$. Over 1.53million visitors came to this festival on the previous year. This design includes an overall masterplan and a series of planting plans along with a core selection of iconic topiaries. The goal of the design is to create a landscape that improves the value of the place image and local economy as well as celebrates the 2014 Incheon Asian Game. In order to achieve this goal, three design subjects were considered: promoting local pride as a part of Incheon, increasing the aesthetic value of the site based on the brand image, and sustainable placemaking. To promote local pride, the 2km long "Little Incheon" is designed over a wildflower field, which is inspired by Incheon Bridge to give a strong image of the locality. A variety of programs from local gardening participation were introduced to the east part of the site. The design also outlines the vision for the development of Dreampark - a people-oriented gathering place for the entire community with spaces that offer a variety of unstructured recreational and cultural experiences. To increase the aesthetic brand value of the festival, it introduced a variety of wildflower beds scattering through the whole site. It creates a strong brand image for the festival and memories that will encourage visitors to return. Various folktales of Asian countries are displayed by autumn flowers and groundcover plants at the centre of the site, which is the highlight of the festival site. For sustainable placemaking, the design preserves the existing trees and reed beds for wildlife to create natural layers of landscape. In addition, facilities and service centers are designed to be flexible and are centred on the needs of the people using them. Also a festival management scheme was planned in order to operate the site efficiently and economically.

This study was carried out to develop a better fruit-dressing than previous mayonnaise in terms of calories, salt content and color, using kiwis, oranges, strawberries, and apples. This study was aimed to identify the perception, physico-chemical and sensory characteristics of the 4-kinds of fruits dressing. The results were as follows: The perception of the fruit dressings received the highest score (3.90) for 'It's convenience foods'. The misture in the dressings ranged from 49.3 to 59.4%, and was highest in apple dressing, followed by the kiwi, strawberry, and orange dressings, in that order. The crude ash for the dressings ranged from 0.8 to 1.4%, and was highest in the orange dressing. The L value was highest in the apple dressing, the a(-) value in the kiwi dressing, the a(＋) value in the strawberry dressing and the b value in the orange dressing. The Ca/ P ratio was about 1.17 : 1. The results of mineral contents analyses were also examined. The calcium, magnesium and potassium levels were highest in the orange dressing. The mineral contents of fruit dressings were 6.7 to 20.4mg/100g for calcium, 6.5 to 20.5mg/100g for magnesium and 67.2 to 182.6mg/100g for potassium. The sodium content of the fruit dressings were lower than in the previous mayonnaise, especially for the kiwi-dressing, which was 30% that in the mayonnaise. As a result of the sensory evaluations of the 4-kinds of fruits dressing, the kiwi dressing received the highest scores (3.50) of all the fruit-dressings in relation to the taste and palatability. Fruit are good for producing dressings that are low in calories and salt, with kiwi dressing proving to be the best of those fruits tested.

This study was performed to determine the effects of the blanching condition (immersion ratio 1:15 (w/v) for 3 min at $95^{\circ}C$, and solution containing 1% sodium chloride) and selected forming agents (dextrin DE=10, dextrin DE=20, ${\beta}$-cyclodextrin; each forming agents added 5%) on the phytochemical compounds and quality characteristics of Ligularia fischeri leaves. The moisture was not affected by the forming agent. The color of a, b and chroma values were low in the blanching treatment groups and were significantly lowest with ${\beta}$-cyclodextrin (CD). The polyphenol and flavonoid contents in the blanching treatment groups were higher than those in the non-blanching-treatment group. The ascorbic acid content was higher in the non-blanching-treatment group and was significantly highest in the group treated with dextrin (DE=10) whereas the blanching treatment groups showed lower dehydroascorbic acid content than the non-blanching-treatment group. The water absorption was higher in the non-blanching-treatment group and was significantly highest in the group treated with CD. The water solubility in the blanching treatment groups treated with dextrin (DE=20) and CD was higher than that in the blanching treatment group treated with DE=10. The total chlorophyll and chlorophyll a and b contents were high in the blanching treatment group treated with CD, and for the total carotenoid contents, the same tendency as that seen with the chlorophyll content was observed. With regard to the particle diameter, those in the blanching treatment groups were lower than that in the non-blanching-treatment group and was significantly lowest in the blanching treatment groups treated with DE=20 and CD. The result of SEM observation showed that the spray-dried powders in blanching treatment groups treated with the DE=20 and CD forming agents had uniform particle distribution.

This study was carried out to develop a kiwi dressing which was lower in calories and a more beautiful color by using Kiwi rather than mayonnaise. This study was aimed to standardize a recipe for Kiwi dressing using sensory characteristics as well as to examine the changes of pH and chromaticity by the storage period. Results of this study were as follows: from the results of sensory evaluation on kiwi dressing using different kinds of oil, the pure olive oil showed the higher scores than the corn oil in the taste, fresh-sour taste and overall palatability. Sensory evaluation scores of kiwi dressings with various amounts of oil were not significantly different, which suggested that use of kiwi for a dressing was a good way to develop a low calorie dressing because the addition of 32% (360g) oil in kiwi dressing could replace the 75% oil used in mayonnaise without my significant differences in the overall palatability. From the result of sensory evaluation on kiwi dressing with different kinds of acid, lemon juice showed the higher scores than apple vinegar in flavor. The kiwi dressing showed the highest scores in the overall palatability and fresh-sour taste when 12% (60g) onion juice was added and in as well as flavor, taste and the overall palatability at 10 days of storage. The pH values of kiwi dressing Increased significantly in proportion to the storage period (p<0.001), and showed the highest pH value of 2.99 at 17 days of storage. Lightness in color showed the lowest value at 3 days of storage and the greenness of kiwi dressing increased gradually, but the yellowness decreased significantly in proportion to the storage period(p<0.001).

This study was conducted to determine the effects and optimum concentrantion of chemical mutagens, colchicine, EMS (ethyl methan sulfonate), MNU (1-methyl-3-1­-nitrosoguanidinenitro), sodium azide $(NaN_3)$ for induction of mutant plants. In order to induce the mutants of Dianthus superbus L, immature seed were pre-soaked in the warter adding each mutagens and concentration of EMS, colchicine, MNU, and sodium azide $(NaN_3)$. Comparision of morphological characteristic and seed germination in each mutant plants differed depending on mutagen sources and their concentrations. When 0.2% EMS were treated on seed, germination decreased to 12% while untreated control was germinated 76.6% for twenty days. Treatments of colchicine appeared higher germination than other mutagen but not survived. The survival rate was extremely decreased in MNU treatment at 0.5mM and chlorophyll-mutant plantlets were obtained by sodium azide treatment at 0.2mM. Chlorophyll mutants were produced by pre-soaking the immature seed of Dianthus superbus L. with mutagen, sodium azide. The control plants appeared normal green leaf color, while mutant plant after mutagenic treatment of immature seed results in yellow­-green stripes and albino in normal green leaf tissue. RAPD was carried out to check the genetic modification of regenerated plants by mutagen treatments at 0.2mM sodium azide. Three polymorphic DNA fragments out of thirty-seven obtained by RAPDs were observed in regenerated plants using five decamer primers.

The purpose of this study is to investigate the quality characteristics of cookies prepared with Loquat (Eriobotrya japonica Lindl.) leaf powder (0, 1, 2, 3, and 4%) for flour. The pH of cookie dough decreased significantly in response to the addition of all levels of Loquat leaf powder (LLP). The spread factor of the cookies also increased significantly with more LLP content added to the cookies recipe. In addition, Hunter's color L and a values significantly decreased with increasing LLP content, whereas the b value was increased. According to hardness measurements, the substitution of 1~4% for LLP resulted in increased hardness when samples were compared to the control. Moreover, the addition of LLP resulted in increased DPPH free radical scavenging activity when compared to the control. The results of sensory evaluation showed that the cookies containing 2% had the highest scores.

This study proposes the difference of awareness and improvement plan of building-related landscape systems through a cognition survey of building owners, public officials, and experts. The main results are as follows. First, all three groups are highly aware of the need to secure urban green spaces. Even if private property rights are restricted, the level of awareness that green space should be secured for public benefit is high. The level of interest in the building-related landscape system was also surveyed to a greater degree. Second, the survey respondents, including the building owner group, answered that there is a need to strengthen the building-related landscape area standards. It can be seen that there is a need to revise the relaxation of the building-related landscape area standards through an amendment of the Building Ordinance in many local governments. Third, most municipalities are not equipped with an organizational system that can promote the work of building-related landscape. It is necessary to newly hire civil servants for landscape design, maintenance, and management specialization, or to expand co-working relationships with related departments. Fourth, building owners are interested in building-related landscape, but they do not know specific management methods and leave the landscape space. The municipality needs to offer guidance on landscape architectural design and construction methods that the building owners can easily follow and to support the voluntary landscape space management on the part of the local residents by supporting the trees. Fifth, in order to improve the building-related landscape system, it is necessary to verify the effect of the building-related landscape and spread a consensus. At the government level, in order to enable building owners to recognize the value of the landscape space in connection with an urban regeneration project, it is necessary to present an example of an excellent building-related landscape installation via a pilot project.

In July 2011, hundreds of garden cosmos (Cosmos bipinnatus) were found to be infected with a white smut in Namyangju. Further surveys in central Korea showed that the disease occurred in all the nine localities visited, with disease incidence rate of >50%. Symptoms manifested as pale-green to chlorotic areas on the leaves, followed by white mildew development on lesions. The lesions usually coalesced and became necrotic, considerably reducing the aesthetic value. Caespituli were initially hypophyllous but later epiphyllous as well. Conidiophores were 10-40 in moderately dense fascicles, hyaline throughout, mostly guttulate, $20-45{\times}2-4{\mu}m$, obtuse at the apex, and had inconspicuous conidial scars. Conidia were solitary, botuliform, hyaline, aseptate, mostly guttulate, apex rounded, base rounded to truncate, $17-24{\times}3.5-5{\mu}m$, hilum inconspicuous, unthickened, and not darkened. Sori were rounded to elongated, resulting in first white and later brown leaf spots. Teliospores embedded in the leaf tissue were subglobose to ellipsoidal, subhyaline to pale yellowish-brown, $12.5-20{\times}10-15{\mu}m$. These morphological characteristics corresponded with those of Entyloma cosmi V$\acute{a}$nky, Horita & Jage. This is the first report of white smut disease of garden cosmos due to infection of E. cosmi in Korea.

Korditwo is a new orchardgrass(Dactylis glomerata L.) variety developed by the National Institute of Animal Science(NIAS) in 2005. To develope the new variety of orchardgrass, 5 superior clones, Dg8533, Dg9518, EDg9133, U8504 and U8519, were selected and polycrossed for seed production. That synthetic variety was designated newly as "Korditwo", and it's agronomic growth characteristics and forage productivity were examined at Suwon from 2001 to 2002, and regional yield trials were conducted in Suwon, Pyungchang, Youngju, Iksan, and Jeju from 2003 to 2005, respectively. "Korditwo" showed medium type growth habit in fall and spring and short in length of flag leaf and upper internode. Plant height of "Korditwo" was similar to that of standard variety, "Ambassador" and heading date was 4 days later than 14th May compared to Ambassador. Characteristics such as winter hardiness, lodging tolerance, disease resistance of "Korditwo" were stronger or better than those of Ambassador, specially in winter hardiness and lodging tolerance. "Korditwo" showed 10% higher dry matter yield(11.3 ton/ha) compared to Amabassador. Nutritive value was appeared to be similar in both varieties.
