In the past, the purpose of urban landscape planning was to beautify cities. Now, that is changing as cities with their own characteristic identities and images are focusing on the making of livable cities. The subject of international competition is turning from a country objective to that of individual cities. To increase the attraction of the urban image will, therefore, be the most important and urgent policy in all cities. A city without global competitiveness will be demoted to a sub-city. This study intends to suggest strategic ways to improve the urban image suitable for Korean cities by the analysis and classification of the advanced cases in other countries. This study can be summarized as follows: 1. The image of cities is promoted by diverse strategies such as establishing landmarks, making meaningful places, hosting festivals and sports events, and making cultural policies. These strategies can be classified by three factors: the landscape and ecological factor, the historical and cultural factor, and the administrative and economic factor. 2. Korean cities are making efforts to promote their images through a variety of ways. Mega cities in Korea are steadily carrying out projects to use the administrative and economic factor such as expanding the infrastructure, supporting enterprises, advertising and marketing with accumulated capital. However, local small cities mainly depend on festivals and simple events or programs that are of interest but which lack characteristic identity. 3. Cities of advanced western countries are upgrading their images by finding and applying strategic methods to reflect characteristic identity and to keep in step with the changes of the times. On the other hand, cities in Japan try to promote urban image with traditional native festivals and with the making of livable places based on resident participation. The central government in Korea needs to establish a master plan considering the regional balance to improve the image of each city. Local governments should carry out these diverse strategic methods. The task after benchmarking advanced cities with beautiful landscapes will be to find an 'All-Korean Style' and apply it to cities with characteristic image.

The objective of this study is to evaluate the preference and visual characteristic of users according to the location of benches at urban community parks. The types of benches are separated into four patterns and located in four representative places at urban community parks. Each relations between visual preference and adjective related factors are calibrated by the estimated results of Pearson correlation coefficient. Moreover, the factors which affect the visual preference are obtained by multiple regression analysis and to calibrate the each factors significant level, the method of multivariate variance analysis is applied. The results of this study are summzrized as belows: 1. Four types of factors which consist the visual characteristic are classified as emotional factor of visual images(aesthetic factor(F1), texture related factor(F2)) and physical factor(physical factor(F3), transformable factor(F4)). Each factor's eigenvalue is appears as 5.27∼1.78 and the eigenvalue of emotional factor of visual images is more higher than the physical factor. 2. The correlation coefficient between visual preference according to the location of benches(X21) and aesthetic factor(f1) is estimated as 0.79, which is highest value among the four factors. And the correlation coefficient of texture related factor(f2), physical factor(F3) and transformable factor(F4) is estimated as 0.14, 0.04 and 0.08 respectively. 3. The visual preference of users according to the location of benches is greatly affected by the emotional factor of visual images(F1, F2) and the physical factor(F3, F4) are poorly related. The results of this study suggest the effective guidelines for the location of leisure facilities. Moreover the design and planning of leisure facilities at the urban community park have to be reexamined. What must be examined from now on is as follows: First, the preference research of rest facilities in the urban park through the multiple approach must be carried out continuously. Second, the research about the visual quality of the environmental sight observed in sitting on the bench as well as the visual quality of the showed object and place needs to be supported. Nevertheless, through this study the utilization into the useful data of the plan and the design for the systematic disposition of landscape architecture equipments centered on the users can be expected.

To consider an identity about traditional folk village, this study analyzes color characteristic of traditional folk village by targeting Cuandixia folk village in China. For method of study, color is analyzed by KSCA(Korea Standard Color Analysis) program and images of color are drawn by I.R.I. Based on these, four results are came out. First, color distribution of Cuandixia is appeared in YR, R, Y, GY order. Furthermore, there are no affiliation of BG, and B but a lot of affiliation of YR. Second, the whole is made up of color that is applied to mist gray/low chroma in the value and chroma stakes. Especially, high chroma is extracted by only commercial old house, the rest is made up of middle and low chroma color. Third, dark color is the most by KS Color System and dark reddish gray and medium gray are occupied most part. Fourth, the whole atmosphere of village is static and hard, and the image is researched as gentle. Through the research, It applies extracted color palette for plan and preservation of traditional folk village. As using the color that is reflected in national and local distinct characteristic, preserving the color reflected in history and culture of the village, and applying color planning considered harmony with surrounding environment, it is expected that it can help to direct the color involved traditional and cultural meaning.

In this study, the analysis carried out on characteristic of planting species and planting density of parks and green spaces in downtown city of Haengjeong-dong in Wonju, Gangwon Province. We found that 8,050 coniferous trees (19 species), 6,037 deciduous trees (61 species) and 77,609 shrubs 103 species were planted in the parks and green space in Haengjeong-dong. However, a conifer Pinus strobus is highly concentrated in all four kinds of places which are neighborhood park, children's park, green buffer zone and landscape green space regardless of their period of construction and usage of surrounding land and other trees were planted in order of Pinus koraiensis, Prunus yedoensis, Acer palmatum, Zelkova serrata, Pinus densiflora. Average planting density of parks and green spaces is $0.03tree/m^2$ for a tall tree and $0.18tree/m^2$ for a shrub, which shows low planting density in most parks and green spaces of Wonju. Also, understory vegetation was not planted enough. Since area of lawn is wide in green spaces, planting density is needed to be increased and tall trees should be planted more. Therefore, we suggest planting more trees in an area where trees are not planted, multi-layered vegetation and increasing in planting density through shrub planting etc., by identifying spaces for trees to be planted within parks and green spaces.

This paper mainly focuses on the Korean Folk Village and Beijing Si-He-Yuan, according to the color theory of hue, value and chroma of Munsell color system to demonstrates the similarities and differences of the traditional upper-class housing between South Korea and China. As the neighboring countries sharing very similar culture and philosophy which owe to the continual communications between China and Korea in the history. The Obangsaek which is derived from the thought of five-elements profoundly and deeply impact on the color selection of traditional housing in both countries. According to the quantitative analysis of photographs, it was found that: 1. The commonly used colors in Korea are Y, YR and neutral color, but in China, people usually used R and GY, especially the high chroma red in Beijing Si-He-Yuan was used as a symbolic color. 2. The chroma preference of traditional housing reveals that people in China used to apply the polychrome and various brightness, on the contrary, the color of low chroma and high lightness were used to be applied in Korea which can give the sense of simplicity and tranquility. 3. Red, one of the Obangsaek affects the color characteristic of Beijing Si-He-Yuan critically but scarcely impact on the color characteristic of Korean Folk Village.

This study was to analyze the relationship between the community or species and environmental variables of the vegetation landscape in Naejangsan National Park. The analysis was performed by the ordination of DCA and CCA. The study was to compare and analyze the species composition status by the layer and the growth characterisics of the following vegetations ; Torreya nucifera community, Quercus variabilis - Acer palmatum community, Q. variabilis community, Q. variabilis - Sasa purpurascens community and Daphniphyllam macropodum community. The results are as follows; 1. The result of the study on the relationshkp between the stand scores of DCA ordination and environmental variables showed that the soil pH, the ammount of AV-P2O5 and the ammount of C.E.C. tend to increase while Pinus densiflora community changes to Q. variabilis - Q. serrata community and finally Carpinus laxiflora species community siginigicantly. The relation between the stand scores of CCA ordination and several enviromental variables suggested that the species of C. laxiflora and C. tschonoskii the species of Q. cariabilis and Q. serrata the species of C. pisifera, P. densiflora and Q. aliana in sequence grows in more fertile soil. 2. As the result of the analysis of the T. nucifera community showed, reproduction did not increase, and the characteristic of growth was not affected. The result is shown in the growth curve that was damaged by the climate and the human interference. 3. The A. palmatum was found to be as minor species in the middle layer and the crown areas did not have sufficient crown. 4. The result of the analysis of the relationship between Q. variabilis community and Q. variabilis - S. purpurascens community showed a decreasing tendency in the growth and number of species. 5. D. macropodum which constituted the dominance species in the middle layer had a nomal growth curve, and then the successional trend of D. macropodum species seems to be located in the climax species.

This study is analyzed the environmental ecological status of Suncheon Bay and its applicable possibility to the selection criteria of UNESCO World Natural Heritage (hereafter Criteria). The study shows that the formation process of the tidal-flats in Suncheon bay could apply to the Criteria VIII, "to be outstanding examples representing major stages of earth's history." The landscape pattern of Suncheon Bay is deduced various patterns based on 5 biotope types: tidal-flat, rice-paddy, field area, coniferous natural forest, and broadleaf natural forest. Its landscape characteristic is a harmonized composition of various landscape including mountains, rivers, fields, and tidal-flats. It is judged that the unique landscape of Suncheon Bay falls under the criteria VII, "areas of exceptional natural beauty and aesthetic importance." In addition, Suncheon Bay, the habitat of the Hooded Crane as internationally endangered species, comes under the criteria X, "the most important and significant natural habitats for in-situ conservation of threatened species." The study shows, however, that any other designation for protected area including national park or biosphere reserve is a prerequisite for designation of World Nature Heritage. In particular, it could evaluate whether it is qualified of the Criteria after the integrated conservation and management to the Sucheon bay as well as the southwestern tidal-flat is preceded.

An experimental system on three point bending notched beams was established to study the fracture process of concrete. In this system, the acoustic emission (AE) was used to build the cumulative generation order (AGO) and dynamically track the process of microcrack evolution in concrete. A grey-cusp catastrophe model was built based on AE parameters. The results show that the concrete beams have significant catastrophe characteristic. The developed grey-cusp catastrophe model, based on AGO, can well describe the catastrophe characteristic of concrete fracture process. This study also provides a theoretical and technical support for the application of AE in concrete fracture prediction.
