  • Recently, environmental issues such as climate warming, ozone layer depletion, reduction of tropical forests and desertification are emerging as global environmental problems beyond national problems. And international attention and effort have been carried out in many ways to solve these problems. In this study, the growth of green was calculated quantitatively using the technique of remote sensing and temperature change was figured out through temperature extraction in the city. The land-cover changes and thermal changes for research areas were analyzed using Landsat TM images on May 2002 and May 2009. Surface temperature distribution was calculated using spectral degree of brightness of Band 6 that was Landsat TM thermal infrared sensor to extract the ground surface temperature in the city. As a result of research, the area of urban green belt was increased by $2.87km^2$ and the ground surface temperature decreased by $0.6^{\circ}C{\sim}0.8^{\circ}C$ before and after tree planting projects. Henceforth, if the additional study about temperature of downtown is performed based on remote sensing and measurement data, it will contribute to solve the problems about the urban environment.

  • This study explores women's Wonsam in the 18th century. Wonsam was women's wedding dress, one of the representative ceremonial garments of Korea. Wonsam began to appear in the excavated clothes around the 18th century, and we can find drawings and records of the period in Yongjae Collections by Kim-kunhaeng. The form of Wonsam after the 17th and 18th centuries showed the changes in which Seop and Mu disappeared in Baeja form of Danryoung(團領) and the right and left symmetry and side slits were highlighted. The change also included wide and long sleeves and Sakdong(색동) colorful strips on the sleeves), Hansam ornaments, and the use of the belt, which means the change of Baeja composition into our traditional costume of the age. Through the Colletions, we notice that women wore Wonsam in different colors and with varying hair accessories according to the nature of ceremony, the social status, and marital status. Concerning Wonsam, the color of clothing for the dead woman was green(喪禮), while that for marriage ceremony was red(婚禮). Wonsam with the light color was for ceremonial clothing(祭禮). The women who served in the palace wore green Wonsam and Geodumi, while a bride at the marriage ceremony wore red Wonsam or a red long-sleeved robe with Jokduri. At the ceremony of Hyeongunorye, women wore Wonsam with a wig. the dead woman wore Yemou.

  • A sidestream contains the filtrate or concentrate from the belt filter press, filter backwash and supernatant from sludge digesters. The sidestream flow, which heads back into the sewage treatment train, is about 1-3% less than the influent flow. However, the sidestream can increase the nutrient load since it contains high concentrations of phosphorus and nitrogen. In this study, the removal of PO4-P with organic matter characteristics and bacteriological changes during the sidestream treatment via ladle furnace (LF) slag was investigated. The sidestream used in this study consisted of 11-14% PO4-P and 3.2-3.6% soluble chemical oxygen demand in influent loading rates. LF slag, which had a relatively high $Ca^{2+}$ release compared to other slags, was used to remove $PO_4-P$ from the sidestream. The phosphate removal rates increased as the slag particle size decreased 19.1% (2.0-4.0 mm, 25.2% (1.0-2.0 mm) and 79.9% (0.5-1.0 mm). The removal rates of dissolved organic carbon, soluble chemical oxygen demand, color and aromatic organic matter ($UV_{254}$) were 17.6, 41.7, 90.2 and 77.3%, respectively. Fluorescence excitation-emission matrices and liquid chromatography-organic carbon detection demonstrated that the sidestream treatment via LF slag was effective in the removal of biopolymers. However, the removal of dissolved organic matter was not significant during the treatment. The intact bacterial biomass decreased from $1.64{\times}10^8cells/mL$ to $1.05{\times}10^8cells/mL$. The use of LF slag was effective for the removal of phosphate and the removal efficiency of phosphate was greater than 80% for up to 100 bed volumes.

  • In this study, we divided the portraits in the reign of King Seonjo into those which were created before and after the Japanese invasion. We then examined various aspect of costumes expressed in the portraits of meritorious vassals. To analyze official uniforms (Heuk-Danryeung), we examined the Samo height; the side wings' type and pattern; the Danryeung pattern; the Mu style; the processing method of lateral lines in Danryeung the rank badge and rank belt, the color of Dabho and Cheolrik, which were undergarment of Danryeung and Heuk-wa. The meritorious vassals' portraits, prior to Imran, were analyzed with a portrait of Han Eung-in, a Gwang-kuk Pyeong-nan meritorious vassals. The Samo was the highest of the Choson dynasties, and the cloud and treasure pattern was identified on the side wings. The Heuk-Danryeung was a dark blue(acheongsaeg) Danryeung of manja-shaped cloud patterns with a large outward wrinkled Mu, and it had a wild goose badge (second rank) and a Sabgeumdae. It did not coincide with the Pumgye(Jaheondaebu) recorded in Gugjo-inmulgo. Reddish Dabho for Dangsang-kwan, green Cheolrik which was undergarment of Danryeung, and Heuk-wa. were identified. After the invasion of Japan, portraits of Hoseong, Seonmu, and Cheong-nan meritorious vassals were analyzed through eighteen portraits, including Lee Hyeon-bok. After the invasion of the Japanese, the height of the Samo's top was much lower and the width of the side wings was wider than before the invasion of Japanese. The Heuk-Danryeung was a dark blue (acheongsaeg) Danryeung of manja-shaped cloud patterns with a stretching backward Mu. Rank badge and rank belts were almost identical with the record, but there were two exceptions (Sin-jab and Kim, Sae-sin). Therefore, it was reaffirmed that the meritorious vassals' portraits were drawn by the Pumgye at the time of appointment. Among the undergarments of Heuk-Danryeung, green Dabho(11), blue Dabho(4), reddish Dabho(3), and blue Cheolrik(10), green Cheolrik(6), reddish Cheolrik(1), and yucheongsaeg Cheolrik(1) were identified, However, it is suggested that the Dabho of Hoseong, Seonmu, and Cheong-nan meritorious vassals should be the reddish Dabho of Dangsang-kwan, which is the same as the previous Imran, and a green Cheolrik.

  • In order to prepare a basis for ecological restoration of the Seoul Metropolitan area, ecological diagnoses on soil physico-chemical properties and vegetation structure were carried out. Land use patterns, actual vegetation, and biotope patterns were also investigated based on aerial photograph interpretation and field checks. I formulated landscape elements overlaying those data and evaluated the ecological value of each element. Soil pollution was evaluated by analyzing soil samples collected in each grid on the mesh map, divided by 2km $\times$ 2km intervals. Soil samples were collected in forests or grasslands escaped from direct human interference. Soil pollution evaluated from pH, and SO$_4$, Ca, Mg, and Al contents of soil was more severe in the urban outskirts than in the urban center. Those soil environmental factors showed significant correlation with each other. Vegetation in the urban area was different in species composition from that in suburban areas and showed lower diversity compared with that in the suburban areas. Successional process investigated by population structure of major species also showed a difference. That is, successional trend was normal in suburban areas, but that in urban areas showed a retrogressive pattern. The landscape ecological map of Seoul indicates that the urban center lacks vegetation and greenery space is restricted in urban outskirts. Such an uneven distribution of vegetation has caused a specific urban climate and thereby contributed to aggravation of air and soil pollution, furthermore causing vegetation decline. From this result, it was estimated that such uneven distribution of vegetation functioned as a trigger factor to deteriorate the urban environment. I suggested, therefore, a restoration plan based on landscape ecological principles, which emphasizes connectivity and even distribution of green areas throughout the whole area of the Seoul to solve this complex environmental problem. In this restoration plan, first of all, I decided the priority order for connection of the fragmented greenery spaces based on the distances from the core reserves comprised of green belt and rivers, which play roles as habitats of wildlife as well as for improvement of urban environment. Next, I prepared methods to restore each landscape element included in the paths of green network to be constructed in the future on the bases of such preferential order. Rivers and roads, which hold good connectivity, were chosen as elements to play important roles in constructing green network by linking the fragmented greenery spaces.

  • The modern trend in costumes, influenced by postmodernism, is to use of various patterns and images borrowed from diverse cultures of many ethnic groups. The Yo tribe studied in this paper is miner ethnic group in China, whose traditional costume is very splendid and modern. In addition, its embroidery pattern has a high artistic value in that its shapes are diverse and splendid and each one has its own peculiar elegance. As for the research method, I examined the Yo tribe's history, culture, traditional costumes and design patterns through related books, research papers, internet sites, and etc. The results of the paper are as follows. The Yo tribe's costumes consist of a jacket, trousers or a skirt, an apron and a belt. Although the color of the costumes is all black, there are splendid embroidery decorations with the colors of red, orange, yellow, green and white on the chest or shoulder part of a jacket, the adjusting lines, cuffs, or a part of a trousers and aprons. The types of the patterns represented in the Yo tribe's traditional costumes are related to nature, ancestor worship, ethnic legends, history, religion, and agricultural lives. The method by which the Yo tribe expressed on their costumes is a "peach-blossom" technique, which uses cross-shaped embroidery with wrap and woof threads. Because it is not apt to express delicate and detailed patterns, the Yo tribe's patterns tend to show abstract and geometrical forms.

  • The rates of litter production and decomposition of litters from grasslands and forests in Mt. Guryong were studied. The annual litter production of Glycine soja showed the highest value 1950.88 g/$m^2$/yr in the grasslands and that in Quercus acutissima, as 2202.38 g/$m^2$/yr in the forests. The highest decay rate of the grasslands was found in G. soja as k=0.713 and that of the forests was in Salix koreensis as k=0.319. The Z values of k in the grasslands was higher than that in the forests. The shortest half-time of the litter decay in the grasslands was 0.9 years in G. soja and the longest one of the forests was S. koreensis as 2.1 years and the longest of all was Q. mongolica as 5.2 years. In the amount of total nitrogen of litters, G. soja was the highest of the grasslands and S. koreensis was the highest of the forest. The content of the total nitrogen in litters was directly propotional to the decay rates.

  • Green landscape plan to the riverfront area of the Han River The Han River, one of the symbolic elements in metropolitan Seoul, structures an axis of waterscape as the openspace crossing east to west of the city of Seoul. As riverside urban motorway(88 Olympic motorway) and riverside public park were constructed by the Han River Comprehensive Development Project in 1986, the necessity of general plan for the in-stallation of envirommental facility belt to conserve living enviroument is being required with relation to, dense residential areas closed to the river Therefore, the goal of the study is to provide better riverview and to increase environmental purifi-cation ability as a large scale waterscape axis by the preparation of landscape plan to the riverfront area of Han River, In order to achieve the goal, the study deals with sectional speciality, the introduction of landscape assessment techniques and ecological approach to given environment. As unity is kept through whole waterfront area, the area is divided into 9 zoning sections to study development methods for each section, and themes for speciality are given to each section, and the. sort of plants which can be symboliged to the area is selected. Also, the planting methods for harmony with the type of road structure and riverscape is offered. Though the study may give significane to the image and the function of riverside road, in con-clusion, the characteristic ecological approach to the river is so limited that has not been reflected enough on the plan. It is expected that the study should be continued, and long-term riverfront openspace plan, environmentally sustainable, should be arepared.

  • It is difficult to define the urban fringe using a specific geographical designation in the physical planning system because the existence of the urban fringe is certainly not equal in all directions from the inner urban area to the rural area, and is often a discontinuous spatial phenomenon from the inner fringe to the urban shadow. Nevertheless, the urban fringe raises land use management issues which stem from its own peculiar set of land use characteristics. For example, in the UK, how the public can enjoy access to the countryside in the urban fringe while at the same time recognising and acknowledging the importance of landowners and farmers property rights\ulcorner how can a poor quality environment and degraded landscape be improved aesthetically and physically to meet the multiple recreational needs of a diverse population when local authorities are confronted with limited ability to fund and acquire land for these purposes\ulcorner The challenge of addressing these land use management issues necessitates approaches which build a coalition of interest groups and public and non-government organizations in the management processes in order to improve the physical, economic and social environments and facilitate the management mechanism.
