The objective of this study was to investigate the landscape structures of the National and Provincial Forest Parks in the list of "100 Famous Forests of Korea" designated by Korea Forest Service by comparing them with those of the non-designated forests. Among the designated and the non-designated, 34 mountain forests were chosen respectively over all provinces of Korea. The spatial characteristics of forest landscapes were quantified as the landscape indices independently using FRAGSTATS and the two sets of results of analyses were compared each other. According to the results of the comparative study, the designated forests were found on the higher elevation with the higher average slope and the more complicated relief conditions rather than those of the non-designated. In terms of landscape structure, the designated forests show the larger average patch size, the lower edge density and the higher diversity of landscape components. These results indicate that the more hilly mountain forests with the more complicated spatial distribution patterns of patches are the characteristics of the designated forests. The indices of the forest landscape structure would be useful in understanding the perception of forest landscape.

This study investigated the efficacy and drawbacks of a trekking accident prevention programs of the Jirisan National Park using visitor survey data. In total, 394 visitors were surveyed at the entrances to Seongsamjae, Jungsanri, Baekmudong, and Ssanggyesa trails on both weekdays and weekends. The trekking accident prevention training course has not been widely publicized. Only 23.4 % of the survey respondents have participated the training course. The training course itself appears to be useful in that 51.1 % of the course participants positively responded the contents of the course, suggesting that, if well publicized, the program can help prevent trekking accident. The trekking time regulation was relatively well publicized. Of the survey respondents, 72.4 % were aware of this regulation, and 72.2 % of them agreed on applying this regulation to other national parks. Accident vulnerability analysis shows that respondents who were aware of the regulation tend to be more experienced and skilled in trekking and more prepared for accident than those who were not. Also, respondents who were satisfied more on park safety facilities tend to be more experienced and skilled in trekking and more prepared for accident.

This study was performed to analyze time series landuse pattern of urban areas and the change of the areas by using remotely sensed multiple sensors. The results were as follows. First, according to the result of time series analysis, most agricultural land has been changed into built-up areas by development work such as the land development or land readjustment project, arrangement of science parks or military facilities, and location of public establishment like government buildings. Second, if the expansion of built-up areas maintains the present scale and speed, it seems that a lot of parts of land would be changed into built-up areas, especially centering around agricultural land, so it is necessary to establish the plan for urban space. Third, I have synthetically collected the data of the project of urban development and systematically monitored the process of in expansion the built-up areas up to now (from the past). I hereby could lay the foundation that makes us scientifically forecast the direction of expansion in the built-up areas by the urban development in the future.

Various policies and studies regarding use of PBSS (Public Bike Sharing System) and Programs (PBSP) have been conducted worldwide as the number systems or programs has increased. Although various phenomena and demands have been generated by the use of PBSS in everyday life, the majority of research and the policies in South Korea have been implemented focused on commuting life. The purpose of this study aimed to understand various PBSS demands using PBSS usage data in 2018 in the Yeouido districts through classifying usage patterns and analyzing features. The rental stations were classified into three types based on weekday/weekend usage rates. The usage of Yeouido's PBSS accounted for 4.3% of the total usage in Seoul Metropolitan City, while the number of PBSS rental stations accounted for 2% of all rental stations in the Seoul urban areas. Rental stations with a higher weekday utilization rates showed high utilization rates in all four seasons and were mainly distributed in work and residential areas. Other stations showed a concentrated usage pattern in spring (April-May) and autumn (September-October) seasons, and their locations were close to the entrance of nearby parks. Besides, renting and returning were often concentrated at certain rental stations for high weekend utilization as compared to the pattern of high weekday usage. Therefore, PBSS management and programs should be operated to reflect various usage demands rather than uniform PBSS operations. The result of this study is meaningful to provide basic data for effective PBSS operation by monitoring the demand for PBSS usage in spatio-temporal terms.

Ttukseom was once a suburban area that had a government horse ranch for national use and a naenogpo (area of royal farm land). During the Japanese colonial period, a pleasure ground was built at Ttukseom, and after independence, it has been used as a park through the process of urbanization. This study examines the creation of the Ttukseom Pleasure Ground and the process through which the pleasure ground were transformed to a park. This study also explores its landscape and cultural aspects. In the 1930s, Gyeongseonggwedo (京城軌道), a private railway company, built a pleasure ground at Ttukseom to attract passengers, according to the business model of Japanese railway companies, in which recreational areas were developed near railway routes. Mass media portrayed this area as a "rural landscape" in contrast to the city. The Ttukseom Pleasure Ground emerged as a popular summer resort for Gyeongseong citizens. At the same time, it was managed by Gyeongseongbu (京城府). The city of Seoul began to manage the Ttukseom Pleasure Ground following independence, and development plans for Ttukseom as a pleasure ground or a park were continuously drafted but never implemented. Even after Korea's independence, the operation and use of the pleasure ground did not change significantly from the colonial era. In the late 1980s, the Ttukseom Pleasure Ground became the Ttukseom Han River Citizen's Park, and the sandy beach of the Han River was removed. Nonetheless, the previous facilities and major activities such as an open-air swimming pool, camp ground, and areas for boat recreation remained as major park programs. When the urbanization of Ttukseom was completed, its idyllic image disappeared and it became a park instead of a pleasure ground. Since parks expand their programs, it can be concluded that by providing those kinds of programs, the Ttukseom Pleasure Ground transformed to a park.

This study aimed to validate the ASTER surface temperature using field measurements over various land use types in the urban area of Changwon City, South Korea. The ASTER surface temperature was measured by collecting eight images during daytime and nighttime in June and September from 2012 to 2014, and field measurements were conducted over the same period when the satellite images were taken. The analyses showed that the surface temperature measured in the field during the daytime was higher than that of satellite imageries by $5{\sim}10^{\circ}C$, and the gap was higher in built-up areas. The calibration models of surface temperature showed a 60% explanatory power in areas other than parks, indicating that the models are reliable. During nighttime, except for the summer month of August, ASTER surface temperature was determined to be approximately $2^{\circ}C$ higher in contrast to daytime.

This study is conducted to prove a hypothesis that Dokdo Island has "National Landscape Image," being a region with special meaning for Korean people. University students(51 Koreans and 44 foreigners) were surveyed on landscape images of Dokdo Island, and the statistical analysis of the survey responses was performed subsequently. The findings showed no substantial difference between the opinions of Korean men and women: Especially the photo of whole Dokdo was highly rated by Korean respondents as "considerably or very valuable and impressive, but also mysterious and symbolic at the same time." These are unique images of Dokdo Island, which are not found in responses to natural landscape of other national parks. Meanwhile, there were significant contrasts between the responses of Koreans and foreigners in every variables. Some landscape adjectives used as semantic differential scale demonstrate remarkable differences between Korean and foreign respondents, particularly on the photo of whole Dokdo: impressive(1.41), mysterious(1.25), symbolic (1.00), valuable(0.98), intimate(0.95), beautiful(0.93), interesting(0.85). There were substantial differences in responses between Korean and foreigners on two rock islands, which have names related with some national image: The Korean Peninsula Rock(0.57) and Independence Gate Rock(0.51). Finally, three primary factors drawn from the factor analysis were (1) national landscape image, (2) natural characteristics of Dokdo Island, and (3) spatiality of Dokdo Island.

This study analyzes the Pattern Language of Insadong-gil in street environmental design analysis for street vitalization. The urban public spaces, such as pedestrian streets, parks and plazas, have been increased with rapid urbanization and industrialization. But the fact is the satisfied spaces with the behavior patterns of users is little. This is because of the too much slanted thought toward formal supply and management of spaces without enough consideration for people and spatial quality of public spaces. The purpose of this study is to find out the factors to make the street more vital and diverse and to give the characteristic of region through the research on Insadong street with the pattern language of Christopher Alexander. So, throughout the value recognition of the changing urban street environment that has been changed by age selected spatial characteristic of public spaces. By selecting a suitable pattern language for each spatial characteristics provide the basis for street environmental design analysis. For this study, look at the relationship between pattern language focused on Insadong street, pattern language as the vitalization factor of street were analyzed 16 elements, including Pedestrian Street(100), Building Fronts(122), Activity Nodes(30) etc. This study focuses on street environmental design analysis of Insadong-gil through the Pattern Language, it propose the criteria and guidelines that will help enable street vitalization.

A BIM, which is being applied actively to the construction and civil construction industries, is a technology that can maximize efficiency of various sectors from initial planning and design, construction, and maintenance, to demolition; however, it is in the introductory phase in the field of domestic landscaping. In order to introduce and promote BIM in the field of landscape design, this study developed a prototype of a library and template and analyzed the performance of trial application. For the development of a prototype, annotations and types were analyzed from floor plans of existing small parks, and components of landscape template were deduced. Based on this, play facilities, pergola, and benches were madeintofamily and templates, making automatic design possible. In addition, annotations and tags that are often used in landscape design were made, and a 3D view was materialized through visibility/graphic reassignment. As for tables and quantities, boundary stone table, mounding table, summary sheet of quantities, table of contents, and summary sheet of packaging quantities were grouped and connected with floor plans; regarding landscaping trees, classification criteria and name of trees that are suitable for domestic situations were applied. A landscape template was created to enable the library file format(rfa) that can be mounted on a building with BIM programs. As for problems that arose after the trial application of the prepared template, some CAD files could not be imported; also, while writing tables, the basis of calculation could not be made automatically. Regarding this, it is thought that functions of a BIM program and template need improvement.
