This is an empirical study to investigate the types of plants used in Gertrude Jekyll's wild gardens, identify relationships between plants, and analyze the planting patterns. Four sites were chosen for the study: the Cotswold Cottage, the Dryton Wood, the Little Aston, and the Frant Court. To find direct relationships between plants from the planting patterns shown in these gardens, the social network analysis program R was used to analyze degree centrality, which resulted in the identification of top three plants, followed by looking into their characteristics and meanings. The summary of the results is: Azaleas(Rhododendron spp.) showed the highest degree centrality, followed by wild roses (Rosa spp.). Cold-resistant crossbreed azaleas were used as underplanting connected to many different plants, creating the feeling of an atypical woodland garden. As an indigene, wild roses showed high degree centrality in terms of ecology and aesthetics, forming multiple layer planting. Also, plants with small white flowers, for example rowans(Sorbus commixta), shadbush(Amelanchier asiatica), sealwort(Polygonatum odoratum), and American columbines(Aquilegia vulgaris) were planted in these wild gardens as plant colonies to make natural connections with other plants through drifts.

The number of species and individvals of birds observed in Bibong, Chinju-castle, Nosan and Saho parks were 49 and 4,349, 46 and 6,453, 37 and 2,817, and 33 and 6,014, nespectively The dominant species in all survey areas were shown in the order of Passer montanus(21.8%), Aegithalos spp.(20.7%), Pica pica(8.7%), Hypsipetes amaurotis(7.6%), Parus major(6.4%), Carduelis spp.(4.6%). Migration of birds was the order of residents, summer visitor, winter visitor, and passage migrant. The number of bird species appeared was the fewest in winter as 40 species and the most in spring as 53 species. Species diversity was the highest in Bibong park as 1.3256 and followed in the order of Sanho park, Nosan park, and Chinju-castle park. The nesting guild was higher at outside and artificial nesting guild(7-15 species) compared with hole, canopy, bush nesting guild(1-7 species) in all survey areas. The breeding forage guild was higher at canopy and bush(12-25 species) than that at outside, artificial, and air forage guild(2-8 species).

This paper aims to analyze the satisfaction level of people for the different types of tree burial sites, in order to suggest directions for the policy to revitalize tree burials. For the purpose of this study, the tree burial sites were classified into four types, and we conducted a questionnaire, targeting 414 visitors to the different case sites. Through the comparative analysis among the case sites, this study found that people prefer the public tree burial sites to the private ones, and most people liked the type of tree burials best created in a natural forest among the public sites. Based on these results, this study suggested that the policy should be focused on the revitalization of public tree burial sites created especially in natural forests in order to satisfy the preference of people. Through the analysis of the questions regarding the general citizens' awareness of tree burials, this study found the improvement measures are required for convenience facilities, low satisfaction for usage charge, low credibility for private tree burial sites, and strong demands to create stable growth environment for memorial trees. On the other hand, this study confound the bright prospect for the spread of tree burials because people who have used tree burial sites were highly willingness to recommend tree burial sites to others and they wanted to do a tree burial for their own funerals.

The U.S. Conservation Reserve Program (CRP) resulted in the conversion of approximately 14.8 million ha(36.5 million acres) of cropland to grassland, woodland, and other conservation uses throughout the U.S. between 1986 and 1992. One of the major results of CRP has been the addition of millions of hectares of potential wildlife habitat. primarily as grassland. In this study, we examined regional changes in landscape structure caused by the introduction of CRP. Utilizing multi-seasonal Landsat Thematic Mapper imagery, we produced maps of cropland and grassland for the pre- and post- CRP enrollment periods for a six-county region in southwest Kansas. We then applied post-classification differencing to identify regions of cropland that had been converted to CRP. Using the FRAGSTATS spatial pattern analysis program, we calculated a variety of spatial statistics to analyze changes in landscape structure due to CRP. The major impact of CRP in the six-county study area has been the reversal of an overall trend of grassland habitat fragmentation. From the standpoint of potential wildlife habitat, the introduction of CRP has greatly increased the number of patches, mean patch size, and the interior or core area of grassland patches. In addition, CRP has increased connectivity and aggregation between grassland patches, potentially important factors for species of conservation interest, particularly those that require larger expanses of unbroken habitat. Finally, the distance between neighboring patches of grassland has decreased, reducing travel distance between patches. Clearly, the introduction of CRP has substantially modified the spatial structure of the southwest Kansas landscape, with important implications for wildlife habitat.

Nam Khane watershed, in the Northern Laos, consists of limestone plateau surrounded with steep slope(above 1000m), wide piedmont hill land(300-700m) and narrow alluvial plain. Opium on the plateau and up-land rice on the hill-side are cultivated for each, but its shifting agricultural activity, which degrades the forest and soil, has caused the serious environmental problems. MOS-1 satellite image and 40 points of soil samples are analyzed to identify the distribution of the shifting cultivation and to evaluate the environmental problems for Nam Khane watershed. The land use classification map is presented on the photo 2, and the value of each land use area by elevation level and soil property are showed on the table 2 and 3, respectively. Excessive agricultural activity of shifting cultivation in the Nam Khane watershed not only decreased the forest area, but also changed the primary forest of tree into secondary woodland of shrub. On the phase of soil property, it accelerated the soil and gully erosion, and acidification. To solve these environmental problems, the most important step is to settle the agriculture from shifting cultivation to permanent cropping.

Genetic variation in Asaum misandrum, a woodland herb in Korea, was investigated based on allozyme analysis with starch gel electrophoresis. All of previously reported populations in Korea were sampled and seven loci from six enzymes were analyzed. Overall genetic variation of A. misandrum population showed considerably high levels of genetic variation within the species (A = 2.05, P = 71.4, $H_E$ = 0.294). A positive $F_{IS}$ value of A. misandrum indicated overall deficiency of heterozygotes, and a low $F_{ST}$ value (0.112) meant very little differentiation among populations. Factors contributing to the high levels of genetic diversity found within populations of A. misandrum include population maintenance via wide distribution range from Korea to Japan and primarily outcrossing breeding system. Although it showed moderate genetic diversity level, most habitats of the species were scattered and discontinuous. Besides, low numbers of individuals were found in the most habitats and individuals are collected frequently from the wild due to the unique shape of the flowers as well as the rarity of the species. Thus, there is a need to set up a reasonable conservation strategies including the maintenance mechanism of genetic diversity of A. misandrum.

The purpose of this study is to investigate about security service history on 1930s in Korea. This study used materials by historical facts for the regulations, books and newspapers in 1930s. In 1930s, security service was unknown details of the historical contents so far. There are four parts conclusion of this study: police department of provisional government, security service agency in the provisional government, security service agents of an independence movement, the general society of Korea. Firstly, Korean regional government in Manchuria, which Kokminbu(國民府) organized the security service agency(警護局) for protect government and public security. Most importantly, the security service agency appearanced an important place which were the independence movement and self-governing administration for Koreans in Manchuria. And the security service agency was required by the security service regulations(警護條例) as law. Secondly, diversity activities of security service in police were exposed the duty as 'car escort service(車輛警護)' for offenders, the 'township office guard' from mobsters, 'woodland protect service(林野警護團)' for fire-raisers. security service as police officer were widely application for protection and safety from danger. Thirdly, Mass society was needed to service for public security in daily events such as 'noted singer meeting', 'funeral procession to the graveyard', 'athletic meeting' as private establishment of security service agency in nowadays. people were wanted the private security service(私警護) from 1930s to present. Fourthly, Overseas security service mentioned in attack of politician, protect from poison and security service about train vessel fleet. In 1930s, security service is comprehensive protection which were not only bodyguard, but also safeguard for hazardous materials.

The recently-introduced Special Use Permit system is an exceptional approval system for private park developers to develop unexecuted urban park sites into urban parks with the implementation of profit-generating businesses within the boundary of preserving the original function of the park under an agreement with local authorities. This thesis studies the application of this system. This is a feasibility study of cases that have contributed to the acceptance of intended park sites by developing some parts of park sites as public housing, focused on unexecuted urban park areas for the long term in Suwon City based on the Special Use Permit, and creating other sites as park area. First, it has been judged that realization of business is possible at 300 percents of the floor area ratio in case of flatland neighborhood park which has high appraised land values. It is judged that realization of business is possible within a 10 percents size of private land at 200 percents of the floor area ratio in case of woodland and waterside neighborhood parks that have low appraised land values on the outskirts of the city. Second, through working expenses combining compensation and money for park construction, a balance of business profit can be understood within about 50 percents of total expenditures. Because the public contribution ratio by the Special Use Permit can be presumed as about 50 percents of total expenditures, it implies that windfall profits by the Special Use Permit can be adequately collected.

The survey was carried out in the Goryeong area in Gyeongbug province to point out the hinderances of grave increment on the development of hilly to mountainous area and to give basic data to improve the entombment custom. The total extent of gravesite in the area was mapped 148ha which were 0.4% of total area and 1.8% of arableland respectively. Scattering of graves might be hindered utilization of the mountainous area. Out of the total gravesite, about 60% was situated on the areas of 30-60% slopes, and the occupation extent in average was about $89m^2$ per grave which was wider than that of the national average $52m^2$. The soils occupied by gravas ware characterizod by having recommendable properties about 73% for grassland, about 17% for woodland and 8% for orchards.
