Trachytic cliff showing a unique appearance like noodle is located in the Mt. Bipa, Seo-myeon, Ulleung island. This cliff is named 'Guksubawi'(means noodle-like rock) by its appearance. There is cliffs on three sides except north side and each side shows semi-vertical columnar joints obviously. This columnar joint has different character in appearance and mineralogy according to their direction and this tendency is remarkable in contrast between the east side and the west side. The consideration of the cooling processes after eruption of trachytic lava based on the contrast of both columnar joints dealt in the full text. In the morphological approach, the columnar joint on the east side has narrower space and chisel-like marks than the west side. And the joint walls are sharper on the east side than west side too. In the mineralogical approach, then, trachyte on the west side has bigger phenocrysts than the east side and is showing glomeroporphyritic texture and weak trachytic textures of lath of plagioclase. Around these differences between the east side and the west side, it modelled the typical temperature gradient while the cooling processes of hot rocks and the east side, consequently, corresponds to exterior of the entire trachytic volume. The columnar joint of the Guksubawi has the value of landscape and scientific importance about the forming processes of the columnar joint of trachytic lava, and so supposed it has enough values to preserved as natural heritage.

This report is based on the investigation of potholes which are formed by fluvial erosion. A pothole is called so because it is a hole that looks like a coffeepot. The results of previous studies are applied to the 'Jakgwaecheon Porthole' of this study. The study is focused on the dimension and morphology of the Pothole and investigates the effects of stream sediments, river flow, geological structural lines, etc. on the formation of potholes. As a result of measuring 61 potholes in this area, we recognized that the elliptical dish-shaped cross sections are dominant and inferred that their longitudinal direction on the plain is affected by the direction of the stream flow. Also, 'Jakgwaecheon Pothole' is very characterized in terms of scale and morphology. Furthermore, it is harmonious with the beautiful landscape, humanity, and historical values and it can be suggested that it is qualified to be registered as a geoheritage structure.

The Seosan Geomenyeo(black submerged rocks), once located at the Cheonsuman bay of Buseokmyeon in Seosan, Korea, is a reef rock now exposed on the land surface. The Geomenyeo can also be found in the ancient geographic maps around the area. The local geographic names, like Buseok and Buseoksa temple are derived from the Geomenyeo. It is composed of ultramafic rocks complex and intrusive felsic igneous rocks. These rocks show diverse facies with various petrographic characteristics caused by geological processes such as intrusion and alteration. Ultramafic rocks complex can be roughly categorized as coarse grained ultramafic rocks and medium grained mafic rocks. Both cases are composed of pyroxene and amphibole, showing the general rock facies of pyroxenite, diabase and lamprophyre. Felsic igneous rocks includes pinkish medium grained granite, porphyritic amphibole granite and aplite with varied mineral compositions. The Geomenyeo is the only ultramafic rocks complex in the Cheonsuman Bay; moreover, it has a distinctive geological and scenic value, as well as a symbolic property. In order to preserve the Geomenyeo, it is necessary to investigate and promote it as a designated heritage site through academic studies, and compensate for the convenience and protection facilities. Additionally, the Geomenyeo should be evaluated as a maritime heritage site, due to the unique local culture as it succeeds the recognition of forefathers which regarded it as a local scenic site with significance.

This study aimed to find out the formation of ecologically educational place identity of nature trails in national parks, which elementary school students to adults can understand, by analyzing the connectivity between characteristics (signs) of nature trails and elementary science environment-related key concepts and the domain of ecological education in the course of environment and by developing a semiotic interpretation model of place identity based on Barthes's semiotic theory. When analyzing correlations between the interpretation board-focused surrounding environment of nature trails and the content system of ecological education, this study found out that it showed the highest connectivity with the domain of 'System of Ecological Environment'. When analyzing the formation of place identity of nature trails in terms of semiotics, this study discovered that geographical locations or landscapes, artificial environments and physical elements as characteristics of surrounding environments mostly acted on the formation of placeness. Besides, it was found that both knowledge and attachment elements equally could act on the formation of a sense of place. Being likely to develop through interaction between placeness and a sense of place, place identity was mostly composed of behavioral internal stages and sympathetic internal stages. To diversify the formation of place identity, however, this study found it necessary to develop environment education projects and create surrounding environments and interpretation boards with the environmental uniqueness of nature trails reflected much more.

This study aimed to derive the concept and types of school outdoor spaces in Seoul. The research results showed that the concept of school outdoor space can be viewed as an outdoor activity space in schools that secures the value of integrated public life and communal life, including "behavioral rights, walking rights, living rights, urban rights, landscape rights (viewing rights), and nature experience rights." It can also be defined as a basic educational space that reflects the value of education, which is the basic function of schools and the characteristics of the community. As a result of the analysis based on the general types of outdoor spaces, it was found that the outdoor spaces of Seoul schools can be divided into three major categories: walking space (movement function), educational space (educational activities), and rest and other spaces (other services). Based on this, outdoor spaces were categorized and subcategorized to serve as the basis for policy implementation. These classifications are characterized by 1) simplifying the classification of spaces by function into three (movement functions, educational activities, and other services) to enable the use of outdoor spaces for integrated purposes; 2) reflecting the complex use of spaces by subdividing educational spaces focusing on major activities, and in particular, discovering complex spaces due to the three-dimensionalization of buildings; and 3) enabling spatial-level planning and facility element-level access according to school characteristics. It is characterized by applying the recent trends and systems of general outdoor space projects to the current situation of schools.

This study aims to analyze the change process in order to set the improvement strategies for the zoo in the Seoul Children's Grand Park. The zoo can be reviewed through three significant time periods with noticeable changes. As a framework to analyze the major changes that happened in the zoo, this study looks at the changes in terms of the planning aspect as well as the animal welfare and program operation aspect. The findings are as follows: first, the era of general theme park turned out to have focused on exhibiting animals to meet visitor demands by expanding the zoo area of the zoo without enlarging stockyards for the animals. Second, the environmental park era created a zoo having entertaining and educational functions by arranging animal houses with the concept of zoological taxonomy and introducing animal behavioral enrichment, animal welfare programs and visitor participatory programs. The era of the zoo as an Urban Cultural Park improved old animal houses and facilities for the welfare of the animals and increased educational programs to preserve species and provide environmental education. The current status of the zoo turns out not to meet the conditions for creating an ecological zoo, which is the overall goal for contemporary zoos. The improvement strategies based on the analysis through three different eras are three-fold. First, the zoo needs to improve the boundary conditions of the animals to showcase animal wildness through landscape immersion. Second, the zoo should provide a shared environment for animals from the same habitats by changing the classification methods from the existing polyphyletic taxon to a classification that considers ecological habitat. Third, the zoo needs to develop various ecological education programs by supplementing specialists in professional education.

The results of this study attempting to graft to the space by cognizing and categorizing the characteristic of the under-toned private property to the tablets of the Zhuozhengyuan are as follows. The tablet of Zhuozhengyuan was typed into three groups. In the A group, the frequency of artificial elements including the top, ship, and head was high, and the main emphasis was on the elegance and integrity spirit that the Sunbi(classical scholar) had to have. It has a characteristic of good architects such as pavilion and Nu(樓) is included and as it is adjacent to the water surface the one side of the building is integrated to the water surface. The B group is characterized mainly by the fact that the scenery is portrayed through the climatic factors including rain, wind, and snow, or the scene atmosphere and it is located at the top of the summit which is good for viewing the scenery. In the C group, plant elements such as lotus, magnolia, plum, and bamboo appeared frequently, and various buildings such as pavilion, Kwan(館), Gak(閣) and Dang(堂) belong to this structure. The structure has the characteristic of integrating directly with the water surface or putting the terrace between and scattering throughout the whole garden. Furthermore, this study identified area characteristics based on the frequency of the tablet type. In the west area, Group A is mostly distributed and the humor and concept implied in the tablet, combined with the shape and location of the scenery, viewpoint of the viewer, and the composition of the landscape, improved the orderliness of the space, which led to expand the scope of the enjoyment to the entire space. Meanwhile, in the middle area, tablets of Group C are mostly distributed, and the unique characteristics and shapes of the woody plants that were used as the name of the tablet were connected with various buildings including pavilion, Dang, Kuan, and Gak, improving the unique identity of the space and forming connection with the world of ideas through unity and independence.

This study aims to explore the significance of historic changes and cultural characteristics of landscape architecture in Korean Seowon. Seowon refers to educational private institutes that also served as Confucian shrines and were prevalent during the mid-to-late Joseon dynasty. Seowon comprised three distinct functional spaces: a shrine, a school, and a garden. The concept of Seowon's garden extended beyond designed landscapes to include the surrounding natural environment. The importance of landscape architecture in Seowon is rooted in its connection to the educational philosophy of these institutes. During the Joseon dynasty, scholars revered nature as a manifestation of Confucian ideals, and they believed that close engagement with nature was integral to self-discipline and learning. This research investigated fifteen relatively well-preserved garden in South Korea and conducted a comprehensive analysis of their gardens. The analysis revealed two key findings. Firstly, gardens in Seowon were actively designed and constructed during the early phase of Seowon culture but gradually diminished after the 17th century. This can be attributed to the shift in Seowon's purpose, with a greater emphasis on its religious function over education. Consequently, the significance and presence of landscape architecture in Seowon, which was closely related with its Confucianist education, declined. Secondly, the study explored the historical backgrounds of each Seowon's landscape architecture and found that many of them were designed or influenced by individuals who were later memorialized and deified in the Seowon's shrines. The landscape architecture created by these predecessors was carefully preserved by the faculties and students as a form of respect. Therefore, landscape architecture in Korean Seowon not only conveys the institutional purpose as an educational hub for the local society but also reflects the institute's strong relationship with the figures they worship as shrines.

The spring season in Korea features a dynamic landscape with a variety of flowers such as magnolias, azaleas, forsythias, cherry blossoms and royal azaleas flowering sequentially one after another. However, the narrowing of south-north differences in flowering dates and those among the flower species was observed in 2014, taking a toll on economic and shared communal values of seasonal landscape. This study was carried out to determine whether the 2014 incidence is an outlier or a mega trend in spring phenology. Data on flowering dates of forsythias and cherry blossoms, two typical spring flower species, as observed for the recent 60 years in 6 weather stations of Korea Meteorological Administration (KMA) indicate that the difference spanning the flowering date of forsythias, the flower blooming earlier in spring, and that of cherry blossoms that flower later than forsythias was 30 days at the longest and 14 days on an average in the climatological normal year for the period 1951-1980, comparing with the period 1981-2010 when the difference narrowed to 21 days at the longest and 11 days on an average. The year 2014 in particular saw the gap further narrowing down to 7 days, making it possible to see forsythias and cherry blossoms blooming at the same time in the same location. 'Cherry blossom front' took 20 days in traveling from Busan, the earliest flowering station, to Incheon, the latest flowering station, in the case of the 1951-1980 normal year, while 16 days for the 1981-2010 and 6 days for 2014 were observed. The delay in flowering date of forsythias for each time period was 20, 17, and 12 days, respectively. It is presumed that the recent climate change pattern in the Korean Peninsula as indicated by rapid temperature hikes in late spring contrastive to slow temperature rise in early spring immediately after dormancy release brought forward the flowering date of cherry blossoms which comes later than forsythias which flowers early in spring. Thermal time based heating requirements for flowering of 2 species were estimated by analyzing the 60 year data at the 6 locations and used to predict flowering date in 2014. The root mean square error for the prediction was within 2 days from the observed flowering dates in both species at all 6 locations, showing a feasibility of thermal time as a prognostic tool.
