The non-planned development of the rural area surrounding the Metropolitan area has become a social problem. The land development program until now has an aspect of not combining the spacial plan and the environmental plan. The land use and city development system based on development should change into a form that combines developing the area and conserving the environment. Therefore, this research attempts to compare the results of the overlay analysis and the gravity matrix which are ways to evaluate the value land that has a high environmental conservation value. The research area is the town of Seonggeo-eup, Cheonan City, and the reason for selecting this area is because it is expected to be densely populated as a connected area to the Metropolitan and the development pressure, such as expanding the industrial area, is high due to convenient transportation. The environmental factors used in the research are the relative altitude, incline, age-class, natural degree of the ecology, classification of the land covering and the NDVI, and the research methods used are the overlay analysis of the GIS and the statistical method. The overlay analysis results showed level 1 13.2%, level 2 30.7%, level 3 47.4%, level 4 1.0%, level 5 2.4%, level 6 5.4% and so on. The gravity matrix was classified as level 1 27.0%, level 2 9.3%, level 3 58.2%, level 4 2.4%, level 5 2.3%, level 6 0.9% and so on. These results are more appropriate than current methods for plans that value the environment because the analyzed results of the gravity matrix have a tendency to highly condense the environmentally valuable area. Consequently, if the spacial and environmental plans combine and therefore expand the efficient use of the land in the current state where the nation's concern in environment is getting higher, it is thought that it will contribute highly on the development of the nation's life quality.

UNESCO and IUCN established the term of 'Sacred Natural Sites' (areas of land or water having special spiritual significance to peoples and communities) for conservation of biological and cultural diversity. Dangsan forest, a traditional village forests of rural Korea is a representative 'Sacred Natural Site' with a history of more than several hundred years of Dangsan ritual. The Chungmak village, Gyeokpo-ri, Buan-gun is a small seashore village. It is an important place that has the largest ancient maritime ritual sites in Korea. Buan-gun have been tried to register the 'Chungmak-dong Ritual Site' for the World Heritage List. However, the fact that this 'Chungmak-dong Ritual Site'(5~6 century, Baekje of the Three-kingdom period) was located in the Dangsan forest, surrounding the shrine, is not much understood. In this study, the landscape characteristics and culture of the sacred Dangsan forest at Gyeokpo-ri, including Gyeokpo-ri, Dae-ri, Naesosa temple Seokpo-ri, Buan-gun and Dongho-ri, Gochang-gun were investigated. And, the potential of registering for World Heritage, 'Protected Area of Sacred Natural Sites' by linking the four site's Dangsan forests has been investigated. The sacred Dangsan forests in the neighborhood of Gyeokpo-ri have kept their landscape characteristics and retained Dangsan ritual. As a result of SWOT analysis for sacred natural sites, WT(weakness-threat) strategy has chosen as priority strategy. The reason is that there is few management scheme. The Dangsan forests at the neighborhood of Gyeokpo-ri need to be recognized by people in Korea, for their valuable landscape characteristics. The places should be managed and protected to remain as a sacred natural sites in order to be prepared for a World Heritage.

There are lots of forests around the Korean rural village. This study was conducted to investigate the state of the forests by the 15 forests case study of the Kamgok region in Chon-guk-Do province, Korea. The results are as follows. 1. The forests lose mostly original form by the construction of road and forest clearing for the land development business. And almostly the form of the forests is a trapezoid or roundness. 2. The forests were remained on account of the Korean cemetery customs which is burying underground. 3. The conservation of the forests becomes more difficult because of the continuous development pressure. 4. Because the scale of the forests is so small, they aren't named as the natural resort forest by the forest law. So it will be the better alternative that they are conserved and used by inducing the concept of the village resort forest. 5. Because the owenership of the forests exists in a person or a family, the forests will be destructed continuously by the cemetery development. 6. The vegetation of the upper trees in the forests is the simple forests of Pinus densiflora, Pinus rigida and bamboo. The height of upper tree is average 10-12m. And average root diameter is 13-29cm. The age of the tree is average 50 years old. The state of the forests is mostly fine. 7. It is clarified that the price of the forest land is 3-5 times expensive than the other cultivated land. 8. The forests were made by the forefathers for the purpose of the practical use and were reforested in the era 1960s, 1970s.

Polygalacturonase (PG) gene is a typical gene family present in eukaryotes. Forty-nine PGs were mined from the genomes of Neurospora crassa and five Aspergillus species. The PGs were classified into 3 clades such as clade 1 for rhamno-PGs, clade 2 for exo-PGs and clade 3 for exo- and endo-PGs, which were further grouped into 13 sub-clades based on the polypeptide sequence similarity. In gene structure analysis, a total of 124 introns were present in 44 genes and five genes lacked introns to give an average of 2.5 introns per gene. Intron phase distribution was 64.5% for phase 0, 21.8% for phase 1, and 13.7% for phase 2, respectively. The introns varied in their sequences and their lengths ranged from 20 bp to 424 bp with an average of 65.9 bp, which is approximately half the size of introns in other fungal genes. There were 29 homologous intron blocks and 26 of those were sub-clade specific. Intron losses were counted in 18 introns in which no obvious phase preference for intron loss was observed. Eighteen introns were placed at novel positions, which is considerably higher than those of plant PGs. In an evolutionary sense both intron loss and gain must have taken place for shaping the current PGs in these fungi. Together with the small intron size, low conservation of homologous intron blocks and higher number of novel introns, PGs of fungal species seem to have recently undergone highly dynamic evolution.

Geoparks are worth preserving in an environmentally and heritage. Monitoring and public attention are essential for the conservation and protection of geoparks. The use of Unmanned Aerial Vehicles and the Structure from Motion algorithm enables effective monitoring of geoparks that are difficult to manage due to their wide range of manpower, and various spatial data derived from SfM can be utilized to improve awareness of geoparks that have been lacking. In order to prove this, firstly, we created the 3D spatial data by using the UAV and the SfM algorithm, which is one of the National geoparks of the Hantan-Imjin River area. Using this 3D data for Virtual Reality and 3D printing. After that, we verified the possibility of promoting the geopark through a simple online survey. Finally, we propose a method to utilize all the generated data from each step to promote and research for geoparks.

Recently, there seems to besome problems in the urban visual landscape as a result of continuous economic growth and industrial development. At the same time, the public has begun to be aware of the importance of visual resources, and the necessity for visual landscape conservation and improvement. Therefore, the development of evaluative indicators for systematic visual landscape planning and design is urgent. The purpose ofthis study is to discover evaluative models and indicators for the diagnosis of urban visual landscapes. This study included the selection of 18 physical indicators(statistical data) by literature reviews, adoption of field and questionnaire surveys at 12 autonomous districts in Seoul and surrounding major mountain valleys and river streams(i.e. Mt. Nam and Han-River). The content of the questionnaire is scenic beauty. Moreover, the linear regression analysis between the scenic beauty mean scores and the physical indicator scores figure out the scenic beauty prediction model. As this study suggests, the most important indicators in urban visual landscapes are 'Greens', 'Park' and 'the number of apartment buildings(higher than 20 stories).' Based on the results, greens and parks should be priority elements to considerin urban landscape planning and design. Moreover, since the number of apartment buildings that are higher than 20 stories has a negative correlation with the scenic beauty score, it can be used as basic data for landscape planning. For the scenic beauty prediction models and evaluative indicators suggest a direction of urban management, each indicator becomes basic data for visual landscape planning and design. In following studies, if physical indicators and case studies are added, the scenic beauty prediction models and evaluative indicators could be more synthetic and systematic. Moreover, the development of physical indicators in three dimensions(3D)(i.e. results from visual district analysis, view surface analysis) could be expected to obtain more general and varied results.

This study analyzed push, pull motivation factors and satisfaction of visitors who visited Yangdong village in order to maintain, conserve and seek for effective utilization of this village. The result of this study was summarized as follows. Firstly, the result was that 'personal relations' has a positive impact on 'regional environment' and 'amenities', 'the pursuit of knowledge' has a positive impact on 'regional environment' and 'amenities' on the correlation between the visit motivation and the visit satisfaction. Secondly, 'the pursuit of knowledge' and 'the desire to new experience' have positive impact on the visit satisfaction on a part of the push factor generally. Physical environment was a only factor that has a positive impact on the visit satisfaction on a part of the pull factors. Thirdly, the intention of recommendation was a only factor to has a positive impact on the visit satisfaction on the correlation between the intention of return visit, recommendation and the visit satisfaction. It was proved that the intention of return visit was strongly associated with the intention of recommendation. This result of this study confirmed the important pull and push factor to enhance the tourist attraction of Yangdong village. It will be helpful to make the preliminary data for planning and conservation guidance of traditional village.

The value of Jeju Batdam has been reexamined as it is listed as a nationally important agricultural heritage and globally important agricultural heritage systems. However, it is already exposed to threats such as reduction of agricultural population and cultivation area. Despite efforts like the agricultural heritage system to preserve traditional agriculture, there is few basic investigation into the current status of Jeju Batdam. The purpose of this study is to estimate the length of Jeju Batdam. We used the continuous cadastral map of Jeju area to extract the boundaries of the field lot. In the cadastral map, the farmland was selected by selecting dry fields, paddy fields and orchards. 300 sample site were selected from the extracted farmland, and the boundaries between the Internet map and the parcels were superimposed and the differences were confirmed on the drawing. After that, field survey was conducted to confirm the boundary of the parcels and the existence of actual Batdam. It is estimated that the length estimated from this study is at least 23,983km and maximum 142,353km, which is at least 1,830km longer than 22,108km announced in 2007. Since Jeju Batdam is based on land parcel boundary, it is an objective and efficient method to utilize intellectual information. In addition, because it is subordinate to farmland, new information can be extracted reflecting the change of land use and make the spatial database based on the cadastral maps.

This study was conducted to provide basic information for development of habitat-based conservation strategies of biological diversity in agricultural ecosystem. The carabid beetle assemblages were examined at four kinds of habitats(levee, dike, forest patch remnants and streamside) from three differently stressed areas located in Paltan-myun, Hwaseong city, Korea: agricultural and forest area(site 1), industrial area(site 2), and residential area(site 3). Pitfall trap samplings were carried out 39 times from November 2000 to November 2002. Our study's findings were that the composition of carabid beetle fauna, dominance species, and pattern of carabid beetle assemblage were different among the habitats. The similarity index was highest between two levees in site 2 and 3, and lowest between hillock in site 2 and streamside in site 3, and that among habitats fragmented by road with high traffic was lower than that among any other habitat types. So, we could know that agricultural land use respectively do an important role in diversity conservation and networking. These findings will be used to establish the land use and management plans in the aspects of conservation of biodiversity.

Three land-use limitations including water hazard, soil erosion and fallow potential were evaluated to define an unfair area. Landscape indices in the unfair areas, defined by evaluations before and after landscape enhancement, were computed by Fragstats v3.3 and compared in order to propose a landscape enhancement plan. The results are as follows: First, as a result of the land evaluation, 388.56ha was analyzed for the 1st class(S1), 623.25ha for the 2nd class(S2), 138.08ha(S3s: 82.47ha, S3e: 51.88ha) for the 3rd class(S3), 230.44ha(N1w: 194.91ha, N1e: 23.09ha, N1es: 13.94ha) for the 4th class(N1), and 67.91ha(N2w: 60. 89ha, N2es: 7.02ha) for the 5th class(N2). The classes under the 3rd class(including the 3rd class) were determined as an unfair area, and proposed landscape enhancement for them. Second, it was proposed that unfair areas with potential water hazards(N1 w, N2w) be restored as a wetland and buffer zone. At this point, the farmers owning these fields could be compensated using the direct payment for landscape conservation(DPLC). Areas witha relatively lower slope(S3e) or a steep slope(N1e) containing soil erodibility potential were proposed to be restored as a sod-culture-applied field and substitute vegetation or potentially natural vegetation, respectively. The unfair areas having fallow potential(S3s, N1es, N2es) were proposed to apply special use crops for the S3s fields, native plants for the N1es fields, and intended fallow for the N2es fields. Third, after landscape enhancement, theforest had higher values in the indices of NP, PLAND, LSI, IJI, and TCA, while paddy and upland had lower values in most indices except NP and LSI. The forest patches increased and were more plentiful with their restoration and had much greater possibility to join with nearby patches. With continued restoration, forest patches will have a large core area and small number of patches due to the conglomeration of patches, which positively influences the species of diversity in the forest patches.
