The objective of this study was to understand the effects of soundscapes on forest landscape preference in the Baekdudaegan protected area. The study sites were selected in Jeombongsan and Sobaek National park selected within the Baekdudaegan. The landscape preference surveys were conducted by using landscape adjectives classified with Nature, Sound, Attractiveness, and Aesthetics. The comparative analyses examined the difference of preferences between only visual landscapes and visual landscapes with soundscapes. The research found out that soundscapes were associated with landscape characteristics, and positively correlated with the improvement in landscape preference. Thus, the research can infer that forest landscape assessment consider visual attributes as well as soundscape cues.

The purpose of this study is to evaluate the preference and image on landscape of before and after the restoration in the four study areas where the restoration project of Baekdudaegan ecological ridgeline was carried out and to explore the change factors of image preference according to restoration project. The study areas were Beoljae, Ihwaryeong, Bijoryeong, and Yuksimnyeong and 248 questionnaires were used for analysis. As a result of the recognition analysis on restoration project of ecological ridgeline, the awareness of the project was low at 2.63, the satisfaction of the project was 3.42, and necessity of the project was 4.07. In terms of the preference analysis for landscape photographs, the all preferences of four sites were improved after the project than before. In the result of the landscape image evaluation, images such as 'lifeless', 'uniform' and 'ugly' were high before the project, however, images such as 'clean', 'tidy', and 'stable' were high after the project. As a result of analyzing the change factors of image preference according to the restoration project, adjectives such as 'beautiful-ugly' and 'open-closed' influenced the preference change in common. These findings can be utilized as the base data for the planning direction for the construction of new ecological ridgeline or the landscape conservation of existing ecological ridgeline.

Recently, improvement of the quality of urban riverscape environment has been emphasized not only by landscape architectural field but also by various professionals in planning and ecology. Regarding to this current movement, the aim of this paper is to highlight major visual elements of riverscape axis as a case study of Shinchon River in Taegu City to suggest some basic guidelines for arranging riverscape in urban area. The study was mainly based on Repertory Grid Development method which was developed in Japan. The method is consist of three steps such as decision of element landscape in study area for slide photos, selection of evaluation items for interview and obstraction of proper evaluation factors. The major findings through this study are as follows; 1) The 12 major visual elements which possibly improve riverscape, based on abstraction of proper evaluation factors, are Dunchi, surface of the water,, equipment of river, buildings near riverside, river vertical and horizontal facilities like bridge, fine view, riverbed, water plant, naturalness, water's edge line, harmony and street trees by order. 2) Total numbers of adjective which describe 12 common factors are 25, such as clean, open, stable, quiet, comfortable, friendly, bright, natural etc. In addition, Dunchi was described 337 times by various adjectives, surface of the water was 200 times and arrangement of river was 146 times which is similar result with the order of 12 influential common factors. 3) Therefore, Dunchi, surface of the water and equipment of river are three most important factors which could create better riverscape. These three factors implies us how we supply good quality of urban river environment for the urban residents.

To evaluate the value of a preserved tree as rural landscape resource, the growth environment and health condition was investigated, and the image evaluation was implemented on land~ape architectural major undergraduate students for zelkova trees in Yesan-gun. The image evaluation results of zelkova trees were as followings; 1) Typical image of preserved tree examined by Semantic Differential Scale were 'Old', 'Big', and 'Good'. 2) The 'big' image of zelkova tree and the height of tree, the width of tree crown, the breast girth of tree, the root girth of tree, the external formation of tree, and the health of tree bark is mutually related. Especially, the correlation between the 'big' and the external formation and the width of tree crown is high. 3) Typical image of preserved tree examined by Likert Scale were 'Natural', 'Green', 'Peaceful', and 'Rural'. 4) The preservation necessity for preserved tree was highly related with the state of ground, and the management necessity for preserved tree was highly related with contamination level and the state of ground. The appropriate management plan for preserved tree are proposed to improve the quality of rural landscape(basis of these results).

In this study, the preferences with regard to floral design in a public space and the correlation between such preferences and the image features of the floral design types were identified. Based on the review of the related literature, the floral designs placed in a public space were classified into three types(the flower bed, container, and three-dimensional sculpture types) according to physical factors, and were classified into two types(the indoor and outdoor types) according to environmental factors. In the floral-design type classified by physical and environmental factors, the flower bed and outdoor types, respectively, were highly preferred. The factor that was found to have the greatest influence on the preference for the flower bed type was 'well-orderedness', which included the adjective categories 'harmonious', 'clean', and 'simple'; that which was found to have the greatest influence on the preference for the outdoor-type floral design was 'identity', which included the adjective categories 'symbolic', 'distinctive', 'harmonious', 'impressive', and 'clean'. It can thus be concluded that the plants that are effectively displayed in a public space can express the nature and identity of the city itself, can be a yardstick for giving value to the city and for evaluating it, and can be important components of the urban landscape. A design that is suitable for the purpose of each public space and that reflects the factors that exert an influence on the users' floral-design type preference should thus be developed.

Based on the result of extraction of common factors executed in order to elucidate the visual attributes of street scenery by types through the rotation of 23 adjective variables by Varimax, the visual attributes expressed after the construction of the facilities using street scenery were anylized to be 4 factors including factor 1 through factor 4. Theexplanation of the 4 factor groups to explain the entire distribution was 65.3% and these factor groups are the psychological attributes felt when using facilities are constructed by securing the street spaces in downtowns and the factors were named as naturalness(factor 1), locality(factor 2), identity(factor 3) and clarity(factor 4) respectively. Based on the result of one-way layout distribution analysis, the preferences for street scenery by types were found out to show considerable differences at 1 % significance level. Based on the result of multiple regression analysis, all of the factors explaining preferences including factor 1 through factor 4 were significant at 1 % significance level. In case other conditions are constant, if the values of the adjective variables related to locality(factor 2) increase by 1 unit, the preferences which are the values of dependent variables will increase by 0.709. The variable with the largest relative contribution among the 4 factor groups was the locality(factor 2) factor group and on the contrary, it was found that the independent variable with least influences was the clarity(factor 4) factor group.

Since the 1990s, with the beginning of local autonomy, most Korean cities have tried to establish and reinforce their own identity. The Law on the Planning and the Use of National Land, which took effect in January 2003, requires major and minor cities to manage and develop a city image and a marketing strategy to reflect their current condition. However, many cities continue to experience confusion in implementing urban landscape planning because no efficient and systematic method has been provided for the analysis of a city's image. The absence of systematic analysis methods makes it difficult not only to assess the current condition of a city accurately but also to choose an appropriate policy for the given city. Consequently, many cities suffer excessive trials and errors in implementing the correct policies for their city. The purpose of this study was to analyze the image: of Kongju, which has many historical properties. For this purpose, adjective questionnaires and multi-dimensional scaling (MDS) were made use of in order to assess the city image. The results of this study can be summarized as follows: 1. There are five properties that serve as landmarts lie symbolize Kongju: Muryeong royal tomb, Castle Kong, Mt. Gyeoiryong, Forest Museum, and Kongju National Museum. 2. Based on the citizen survey regarding the city type, Kongju is seen as a historical and an educational city. 3. Based on the image positioning (image spatial plot), Kongju is described as an old and familiar city. There we, however, no landmarks which are in accord with the image of Kongju. It is difficult to establish and reinforce the image of a city with a single element like a landmark However, with steady follow-up research, this study may serve as a systematic and logical model to improve the urban landscape and image.

This study was aimed at improving the landscape agricultural facilities. Agricultural production spaces such as rice paddies and fields are a representative landscape of rural areas. These landscapes should be aesthetically presentable and as such, they require proper landscape planning and management. However, the construction of infrastructure in these landscapes presents environmental and ecological problems. As a result, the unique aesthetics in landscapes such as rice paddies is disrupted by infrastructure development. The construction of infrastructural complexes takes away the pleasantness of the natural landscape. Photographic slides were variable elements were systematically removed in the landscape were used. The original plan and its alternatives (1, 2, 3, 4) in the BV, JV, JG, and GG regions were evaluated using the Likert scale and AHP methods. Statistical analysis was conducted using ANOVA. The results indicate that the removal of variable elements, expansion of separation distance, and the planting of green plants had a positive effect on all parameters. Improvement of landscapes containing infrastructural complexes can be achieved by the use of image simulation.

The Daegu Metropolitan Transit Corporation Advisory Committee has chosen 5 styles of bridge-pier designs, including coating, graphic, planting, billboard and safety-facility style, based on the results of landscape simulations from a previous study. This study was conducted to investigate citizen's preferences and emotional images for each style of bridge-pier design, by aiming at the pilot urban landscape improvement section from Daebong Bridge in Suseong Gu to the crossroads near Dongseong Elementary School in Daegu Metropolitan City. The questionnaire was drawn up regarding the urban landscape improvement plans applied to the research area, and the questions were about citizens' perception of bridge-pier structures generated by constructing a light rail transit, important factors to consider when designing bridge piers, preferences for each style of bridge-pier design and emotional impact. 60.4% of the survey participants were found to perceive bridge-pier structures as unattractive, so it was necessary to improve them aesthetically. Regarding visual factors of bridge-pier designs, color was most important at 5.81, followed by form at 5.57. Regarding aesthetic component factors, harmony was most important at 6.07, followed by amenity at 6.00. In the survey participants' preference for each bridge-pier design, the graphic style was preferred most at 4.14, followed by the planting style. In emotional adjectives used for each bridge-pier design, the coating style, the safety-facility style and the non-treatment style showed similar results, and all of these styles were evaluated as artificial, lifeless and desolate. The graphic style and the billboard style showed different tendencies, depending on visual factors and aesthetic component factors applied to the graphic design used for these two bridge-pier styles. Since natural materials were used for the planting style, however, it showed high preference for such emotional images as natural and lively. The emotional adjective 'amiable' was found to affect citizens' preferences for each bridge-pier aesthetic improvement plan most, and it was also analyzed to have an effect on all the styles of bridge-pier designs. To improve the landscape of a light rail transit being constructed inside the urban area, this study quantitatively extracted citizens' preferences and emotional adjective for every style of bridge-pier design applied to the pilot urban landscape improvement section, and it is expected that the results of this study will be used as basic data to improve the landscape of bridge piers.

The purpose of this study is to improve the understanding of visual perception and to extend the landscape evaluation area by comparing eye-tracking evaluation and landscape adjective evaluation methods towards various type of nightscapes. As a result of the study, it showed that 'blink count', 'fixation duration average', and 'saccade duration average' of eye tracking measurements have a significant correlation with 'beautiful', 'interesting', 'accessible', 'satisfying', and 'safe' regarding landscape adjectives. In addition, there was a tendency toward areas of interests (AOIs) depending on 12 different nightscapes, which showed that the gaze was fixated by focusing on certain landscape elements such as 'door' and 'signs'. These results suggest that the eye-tracking method is an effective tool to specify the evaluation of 'landscape elements' rather than the 'whole landscape' and can be used as a basis to support landscape preference theories, which has been presented as conceptual only. In this way, the results of this study demonstrated the possibility of various applications of eye tracking as an objective landscape evaluation technique, and it is possible to suggest specific implications to landscape planning through the accumulation of continuous research results.
