  • Simulation models allow researchers to model large hydrological catchment for comprehensive management of the water resources and explication of the diffuse pollution processes, such as land-use changes by development plan of the region. Recently, there have been reported many researches that examine water body quality using Geographic Information System (GIS) and dynamic watershed models such as AGNPS, HSPF, SWAT that necessitate handling large amounts of data. The aim of this study is to develop a watershed based water quality estimation system for the impact assessment on stream water quality. KBASIN-HSPF, proposed in this study, provides easy data compiling for HSPF by facilitating the setup and simulation process. It also assists the spatial interpretation of point and non-point pollutant information and thiessen rainfall creation and pre and post processing for large environmental data An integration methodology of GIS and water quality model for the preprocessing geo-morphologic data was designed by coupling the data model KBASIN-HSPF interface comprises four modules: registration and modification of basic environmental information, watershed delineation generator, watershed geo-morphologic index calculator and model input file processor. KBASIN-HSPF was applied to simulate the water quality impact by variation of subbasin pollution discharge structure.

  • An eco-washland is increasingly getting attentions as a new alternative plan for management of water resources because of role as flooding control and ecological park without social and ecological side effects. However, there is a lack of study regarding technological development and ecological guidelines to create eco-washland. This study was carried out to suggest ecological guidelines necessary for engineering process to create eco-washland. A study site was the lower reach of Seokjang stream connecting to Yimjin river, a candidate of new eco-washland, and Kumsa area in Namhan river was selected as a reference site. The analysis of ecological characteristics focused on vegetation, fishes, and birds. Major vegetation communities, composed of dominant species such as Salix koreensis, Salix gracylistyla, Miscanthus sacchariflorus, Phragmites communis, etc., formed physical conditions along with other land uses including open water, sandbar, cultivated land, etc. Dominant species of fishes were some species belonging to Cyprinidae and Acheilognathinae, and in case of birds Anser albifrons, Anas platyrhychos, Anas poecilorhyncha belonging to waterbirds and Paradoxornis webbinanus dependent to forest edge were dominantly distributed. The results showed that complex wetland types associated with partially deep water and upland was the optimal eco-hydrological condition of washland. Cyprinidae and Acheilognathinae in case of fish and Egretta spp. (spring season) and Anas spp. (winter season) in case of bird were selected as target species for the these wetland types. Finally, a detail planning criteria to create habitats of these target species were discussed in terms of spawning, breeding, feeding, resting, refuge, nesting, etc.

  • Due to the increasing demand to utilize water fronts and water resource effectively, a multi-dimensional model that provides detailed hydraulic characteristics is required in order to improve the decision making process. An EFDC model is a kind of multi-dimension model, and it requires detailed 3D (3-dimensional) terrain in order to simulate the hydraulic characteristics of stream flow. In the case of 3D terrain creation, especially river reaches, measurement resolution and spatial interpolation methods affect the detailed 3D topography which uses input data for EFDC simulation. Such results make hydraulic characteristics to be varied. This study aims to examine EFDC simulation results depending on the 3D topographies derived by separate measurement resolution and spatial interpolation methods. The study area is at the confluence of the Nakdong and Kuemho Rivers and the event rain implemented was Typhoon Ewiniar in 2006. As a result, in the case of the area-elevation curve, the difference by means of the interpolation methods was significant when applying the same measurement resolution, except at 160m resolution. Furthermore, when the measurement resolution was 80m or above, the difference in a cross-section was occurred. Meanwhile, the water level changes between interpolation methods were insignificant by the measurement resolution except when the Kriging method was used for the 160m measurement data. Velocity changes emerged according to the interpolation methods when measurement resolution was 80m or above and the Kriging method resulted in a velocity that had a considerable gap in relation to the results from other methods at a measurement resolution of 160m.

  • This study first attempted to catch the transformational affairs and motives of the representative pavilion, Hanbyeok in Honam after its construction. Especially, it re-illuminated the morphologic, significant and functional change process of a pavilion after the early Joseon Dynasty by taking the local scenery, Hanbyeokdang as a sample, and considering the space and scenic characteristics, and diachronically understood its creation process and rebuilt its inherent positional meaning to reach the following conclusion. 1. Weoldanglu, at its early foundation, seems to have stressed the function of a private banquet and lecture hall to train younger students, and served as a reception space. Then the reception function gradually increased, and up to before 1530, it seems to have been called Weoldanglu(月塘樓) or Weoldangwon(月塘院). 2. In 1619, Governor Yoo Saek changed the pavilion name to Hanbyeokdang through the subject of a poem. 200 years after Weoldang's death, it became a public space called Hanbyeokdang, an amusement place in which scholars cultivated great morale, and participated in the sending-off and welcoming of predecessors and successors. This seems to have taken a foothold as a public event or entertainment space for the local administration, Jeonjuboo(全州府) through the remodeling process sponsored by the public. 3. Scenic language such as its indicating name, expression type and surrounding view through old map and so on, the shape of Hanbyeokdang evolved and changed to diverse types after the foundation of Weoldanglu, at the heart of which Hanbyeokdang with its two legs standing at a rock was located. 4. During the late 18th century, Hanbyeokdang seems to have been a wing corridor connected closely to the left corridor of the Jeonju stream bed, whose pattern is presumed to have existed even during the early 19308. Such changes in scenic language make us assume that diverse auxiliary space, a wing corridor, was erected for use as a public banquet and amusement spot of Jeonjuboo Castle, the inherent function of Hanbyeokdang after the mid 18th century. 5. Penetration of Hanbyeokgool and the erection of Hanbyeokgyo caused the change of the ancient shape of Hanbyeokdang. Specifically, a great Hanbyeokgyo passing by the pavilion changed the relative scale, so the pavilion image of pursuing unity with nature has lost the old inherent refinement and visual character.

  • At the beginning of the modern times, orientalism and ethnic character was the main stream of current fashion. Early in the twentieth century, orientalism had a tremendous affect on various areas of society, culture, and art. Particularly, it inspired and activated the design of costume. A great variety of colors and construction of the Orient and geometrical simplicity were based on the creation of modern costume. Ethnic placed weight on the Orient because Japan strengthened competitiveness and China opened the door to foreign countries. Therefore, a large number of the oriental costume produced by a variety of fashion designers. The oriental handicraft, motif and colors of the traditional costume have been used in modern costume. In addition, they are precious ideas for designers. This thesis is about a Study on costume embroidery close to fashion through the oriental embroidery and the concept of oriental embroidery. It is also a study on patterns, skills and colors of the oriental embroidery shown in modern fashion and practical use through the designers works. First, concept, process of change, patterns, skills and colors of the oriental embroidery are mainly discussed. 1.The oriental embroidery consists of life, Buddhism, appreciation and costume embroidery. Embroidery was widely used for a variety of purposes. First, it is to make a good impression and beauty. Second, to decorate many kinds of patterns and shapes. Last, to indicate social status and stages. 2.The origin of the oriental embroidery started in Persia. was It greatly developed in Iran and was introduced in Korea via China. We are reminded of the oriental embroidery of China. China is the original place of oriental embroidery. Oriental embroidery has developed the peculiar embroidery according to each climate, custom and nationality. On the basis of these, the practical use of the oriental embroidery on modern fashion is presented through patterns, skills and colors which leads Korean designers use. Even though the oriental embroidery is not very popular among people owing to a great deal of cost and a demand for labor, the patterns and colors of the embroidery has been already familiar with the contemporaries A more profound study on the oriental embroidery will supply a great deal of material and ideas to the fashion industry. Moreover, an effort to raise self-pride in traditional culture will be also in need.

  • These days sex has become a tool of interest, a constant stream of sex crimes occurs and it brings the age of population cliffs to an age of low birth rates. As an alternative to overcome these problems, we should establish the praying for a child, which has been our ancestors' way of life, as a sacred culture that holds the mystery of life-birth with a new awareness. Therefore, the purpose of this study is not to re-enact the Zhaungam area as a fun and interesting place, but as a sacred place to pray for the nobility, longevity and wealth of life. Based on the spirit of natural love, meeting, healing, and love based on the spirit of traditional culture, Doridori was chosen as the main theme of the project based on the spirit of natural love and life-respect, and the name "Doridori Secret Garden" was given out of 10 medals in Dandong for tourism storytelling. Cultural content becomes a marketing tool for the region and acts as a force for tourists to visit the area. In this context, it was confirmed that the creation of "Doridori Secret Garden" could lead to a high value-added industry that attracts tourists by enhancing the brand value of Andong and showing sufficient significance to become a new attraction. This study is intended to re-create the Zhaungam area as a sacred place to pray for the nobility of life and longevity and wealth of life, noting that people still pray for the birth of their children in Zhaungam and Zhagungam.

  • The purpose of this study was to re-examine the neglected and forgotten Cheongdo Geoyeonjeong, to correct the wrong contents, examine the changes and conditions of the garden, and to establish basic data on the components of the forest in the future. In addition, it was extended to the Gongampungbyeog Cliff, the influence area of the Geoyeonjeongwonlim, and the results of the study were as follows; First, Based on the recitation of "Seonyu pungryu(仙遊風流)" in the "Cheongsuheon-yugo(聽水軒遺稿),", Dongchangcheon Stream and Gongampungbyeog(孔巖楓壁) were influenced by the outer gardens of the Georyeonjeongwonrim. Second, Small pavilion was built and arranged under the rock of Byeongam(Byeongpungbawi) in the management history of Geoyeonjeong Pavilion. The records show that Cheongsuheon used the Geoyeonjeong Pavilion as the original forest and even recognized Oewon, which is a scenic influence, as the Gongampungbyeog Cliff. Third, Many of the poems related to Gongam were recognized as Seunggyeong, which represents the Unmun area, and the eight scenery of Cheongdo and Unmungugok were established here as proof that Gongampungbyeog Cliff was very faithful to the traditional Seunggyeong aspect of Gongampungbyeog Cliff, and the crystalline structure of the location was implied as an external source of Geoyeonjeongwonlim. Fourth, The lower part of Dongchangcheon Stream, which stretches from Geoyeonjeongwonrim to Gongam, is filled with attractions consisting of cancerous areas such as Punghodae, Moseongam, Buangdae, Gokcheondae, Saganjeong, Hakgadae, and Hyeongjeam, which provide a clearer picture of the space and landscape of the Geyeonjeongwonrim Outer Garden. Fifth, The expression "dragging water, spilling it into the courtyard, and sending it back to the downtown of the field" of the Cheongsuheon-yugo suggests that the site of Geoyeonjeong Pavilion was originally a prevention. It is also inferred that Cheng Shu-heon also wanted to respect runners and pursue natural views like runners. Sixth, The record of planting a description of spring water and willow trees in "Geoyeonjeong Manyeong(居然亭晩影)」" and "Sanggukseol(霜菊說)」" suggests that the chrysanthemum was planted and planted, and that the chrysanthemum was used to describe the Osanggojeol(傲霜孤節), which means that he would not yield and keep his incision alone despite severe frost. Seventh, It is believed that the writing was written by Cheongsuheon in 1844 during the period of the creation of the Wonrim. The rock letters on the floor of Geoyeonjeong suggest the names of the receiving and the winning prizes. Most of the passages are based on nuclear power plants, including Muidogyo of the Zhuzi, and most of them incorporate the virtues of the Gunja and the natural views of the Eunja. In addition, the rock writing 'Gyeong(敬)' or 'Uidang(義堂)' is a substitute for special worship objects or introspection, adding to the significance and scenic properties of the Georyeon Garden Forest.

  • The purpose of this research is to empirically trace the junctures of Yigye-gugok managed by Gwan-am Hong Gyeong-mo, a grandson of Yigye Hong Yang-ho who originally designed Yigye-gugok, while reviewing the features of the forms and patterns of gugok. The results of the research are as follows. 1. Ui-dong was part of the domain of the capital during the Chosun dynasty, which also is located in the city of Seoul as a matter of administrative zone. Likewisely, Yigye-gugok is taken as a special meaning for it was one and only gugok. Starting with Mangyeong Waterfall as the $1^{st}$ gok, Yigye follows through the $2^{nd}$ gok of Jeokchwibyeong Rock, the $3^{rd}$ gok of Chanunbong Peak, the $4^{th}$ gok of Jinuigang Rock, the $5^{th}$ gok of Okkyeongdae Rock, the $6^{th}$ gok of Wolyeongdam Pond, the $7^{th}$ gok of Tagyeongam Rock, the $8^{th}$ gok of Myeongoktan Stream, and the $9^{th}$ gok of Jaeganjeong Pavilion. Of these, Mangyeong Waterfall, Chanunbong Peak, and Okkyeongdae Rock are distinct for their locations in as much as their features, while estimated locations for Jinuigang Rock, Wolyeongdam Pond, Myeongoktan Stream, and Jaeganjeong Pavilion were discovered. However, Jeokchwibyeong Rock and Tagyeongam Rock demonstrated multiple locations in close resemblance to documentary literatures within secretive proximity, whereas geography, scenery, and sighted objects were considered to evaluate the 1st estimated location. Through these endeavored, it was possible to identify the shipping routes and structures for the total distance of 2.1km running from the $1^{st}$ gok to the $9^{th}$ gok, which nears Gwanam's description of 5ri(里), or approximately 1.96km for gugok. 2. Set towards the end of the $18^{th}$ century, Yigye-gugok originated from a series of work shaping the space of Hong Yang-ho's tomb into a space for the family. Comparing Yigye-gugok to other gugoks, numerous differences are apparent from beyond the rather more general format such as adjoining the $8^{th}$ gok while paving through the lower directions from the upper directions of the water. This gives rises to the interpretation such that Yigye-gugok was positioned to separate the doman of the family from those of the other families in power, thereby taking over Ui-dong. Yet, the aspect of the possession of the space lends itself to the determination that the location positioned at the $8^{th}$ gok above Mangyeongpok Waterfall representing Wooyi-dong was a consequence of the centrifugal space creation efforts. 3. While writings and poetic works were manufactured in such large quantities in Yigye-gugok whose products of setters and managers seemed intended towards gugok-do and letters carved on the rocks among others, there is yet a tremendous lack of visual media in the same respect. 'Yigye-gugok Daejacheop' Specimens of Handwriting offers the traces of Gwanam's attempts to engrave gakja at the food of Yigye-gugok. This research was able to ascertain that 'Yigye-gugok Daejacheop' Specimens of Handwriting was a product of Hong Yang-ho's collections maintained under the auspices of the National Central Museum, which are renowned for Song Shi-yeol's penmanship.
