The flora of vascular plants and the present vegetation status of Minjujisan and its adjacent regions were investigated from 2000 to 2004, total 27 times. The plant taxa of these areas consist of 764 taxa totally; 172 families, 397 genera, 631 species, 3 subspecies, 105 varieties and 25 forms. There were many useful plants such as 35 taxa of Korean endemics, 12 taxa of rare and endangered plants, and 101 taxa of specially designated plants which were determined by the Ministry of Environment. Furthermore, 46 taxa of naturalized alien plants were also investigated in the boundary of developing areas. The vegetation status of investigated area was comparatively well conserved, but the degree of damage was increasing rapidly by development, deforestation, and tramp which were induced by the disturbances of human beings. Therefore, more active conservation strategies such as expanded designation of conservation area. should be established, and carried out continuously based on the results of long-term monitoring studies.

South Korea presently harbors less than 800 long-tailed gorals (Naemorhedus caudatus), an endangered species. I report for the first time on the taxonomic status and genetic diversity of the Korean species using non-invasive fecal sampling based on mitochondrial cytochrome b gene sequence analyses. To determine the taxonomic status of this species, I reconstructed a consensus neighbor-joining tree and generated a minimum spanning network combining haplotype sequences obtained from feces with a new goral-specific primer set developed using known sequences of the Korean goral and related species (e.g., Russian goral, Chinese goral, Himalayan goral, Japanese serow, etc.). I also examined the genetic diversity of this species. The Korean goral showed only three different haplotypes. The phylogenetic tree and parsimony haplotype network revealed a single cluster of Korean and Russian gorals, separate from related species. Generally, the Korean goral has a relatively low genetic diversity compared with that of other ungulate species (e.g., moose and red deer). I preliminarily showcased the application of non-invasive fecal sampling to the study of genetic characteristics, including the taxonomic status and genetic diversity of gorals, based on mitochondrial DNA. More phylogenetic studies are necessary to ensure the conservation of goral populations throughout South Korea.

This study investigates the crystallinity distribution of ancient silk. Owing to the inherent multi-hierarchical structure of silk protein and the complicated structural changes that occur due to various burial environments, it is challenging but worthwhile to study ancient silk ageing behavior, which is based on the fact that ageing begins with a single fiber and then spreads to a whole fabric. Crystallinity was one of the most effective indicators found to reveal the ageing status of silk. Therefore, a synchrotron radiation-based X-ray diffraction(SR-XRD) method was employed to study the crystallinity distribution of single fibers of ancient silk unearthed from seven archaeological sites in China from historical periods including the warring states, Han dynasty, Song dynasty, and Ming dynasty. In comparison, the conventional X-ray diffraction method, which uses large amounts of samples, was also performed to determine the integral crystallinity of ancient silk. Thermal stability experiments by thermogravimetry(TG) as well as morphology observations by scanning electron microscopy(SEM) and optical microscopy(OM) all confirmed the deterioration of ancient silk. Moreover, the ageing mechanism of ancient silk was proposed with the assistance of an artificial ageing study. The results confirmed the effectiveness of SR-XRD as an ageing indicator, revealing the crystallinity distribution. This research could provide motivation to determine the deterioration status of ancient silk, and would also aid in explaining the fragility of ancient silk due to ageing.

The purpose of this paper is to propose directions for urban greening and nature conservation in small-to-medium-sized cities in Korea for implementation of the Local Agenda 21 (LA 21 hereafter). In this paper, the status of implementation of the LA 21 in both Korea and Japan have been examined. In addition, the green-related plans of both countries have been compared. The cities of Jeonju and Sagamihara were chosen as examples to compare. The result of the research is as follows: 1)With regard to the responsible bodies, in Korea, the implementing plans were initiated by the environment-related authorities of local governments while, in Japan, the plans of action were initiated through consultative committees reflecting opinions from citizens and business entities. 2)Concerning the status of implementation of LA 21, the city of Jeonju has adopted a plan of action and then implemented the plan through a consultative body without adequate legal ground. On the other hand, the city of Sagamihara has enacted a local ordinance to implement the LA 21 It was learned that the newly enacted ordinance has positively been interrelated to existing environmental plans. 3)Regarding urban greening and nature conservation plans, the city of Jeonju has focused on comprehensive measures to preserve and restore ecology while the city of Sagamihara has clearly suggested educational purposes in its plans in addition to preserving and restoring ecology. 4)In terms of support by law or legal system concerned, it has been teamed that, compared with Japan, Korean plans have not been properly supported by law or the legal system to urban greening and nature conservation plans. The same was shown in the city of Jeonju as compared with the city of Sagamihara. As for future directions, the follow are proposed: 1) establishment of a local Committee on Sustainable Development, 2) enactment of relevant and regulations such as the Master Plan of Parks and Green Open paces, 3) establishment of ecological greening plans.

In order to establish the procedures for investigating environmental influences to wooden cultural property, existing study data were surveyed and necessary steps for performing the investigation works were presented to be applied for the future works in this country. Environmental factors which influence to the conservation of wooden cultural property should first be studied for items concerned with their damage situations. On basis of these data, laboratory works to yield the standard value for each factor should be conducted by means of testing samples exposed under laboratory simulated environmental conditions. Outdoor measurements may be followed for samples exposed to the open air at the site of that property. These data may be compared with those of laboratory standard value and overall evaluation for the factor influencing mostly tn the damage status of that property may further be conducted. Referring data obtained in this investigation, necessary measures to be taken for conserving that property may be able to be established.

Present status of Japanese wetland ecosystems and several trials towards rehabilitation and restoration of them are reviewed. Most of wetlands are altered to paddy fields and city areas, and natural wet lowland including tideland is the most endangered nature in Japan. Not only the preservation of natural wetlands but also the conservation of secondary nature of paddy field and waterways in traditional rural areas and restoration of original nature in city areas became the most concerned theme for nature conservation according to the national strategy for the biodiversity conservation. Not only the technological development based on the conservation ecology, but also the development of mitigation banking system are needed in Japan.

The tiger population that once inhabited the Korean peninsula was initially considered a unique subspecies (Panthera tigris coreensis), distinct from the Amur tiger of the Russian Far East (P. t. altaica). However, in the following decades, the population of P. t. coreensis was classified as P. t. altaica and hence forth the two populations have been considered the same subspecies. From an ecological point of view, the classification of the Korean tiger population as P. t. altaica is a plausible conclusion. Historically, there were no major dispersal barriers between the Korean peninsula and the habitat of Amur tigers in Far Eastern Russia and northeastern China that might prevent gene flow, especially for a large carnivore with long-distance dispersal abilities. However, there has yet to be a genetic study to confirm the subspecific status of the Korean tiger. Bone samples from four tigers originally caught in the Korean peninsula were collected from two museums in Japan and the United States. Eight mitochondrial gene fragments were sequenced and compared to previously published tiger subspecies' mtDNA sequences to assess the phylogenetic relationship of the Korean tiger. Three individuals shared an identical haplotype with the Amur tigers. One specimen grouped with Malayan tigers, perhaps due to misidentification or mislabeling of the sample. Our results support the conclusion that the Korean tiger should be classified as P. t. altaica, which has important implications for the conservation and reintroduction of Korean tigers.

The manufacturing technique was studied through the structure and material characteristics of the walls and the painting layers of the Avalokitesvara Bodhisattva mural of Geungnakjeon Hall, Daewonsa Temple. The mural is painted and connected to the earthen wall and the Junggit, and the wall is composed of wooden laths as a frame, the first and middle layers, the finishing layer, and the painting layer. The first layer, middle layer, and finishing layer constituting the wall were made by mixing weathered soil and sand. It was confirmed that the first layer had a high content of loess below silt, and the finishing layer had a high content of fine-sand and very fine sand. For the painting layer, a ground layer was prepared using soil-based mineral pigments, and lead white, white clay, atacamite, minium, and cinnabar (or vermilion) pigments were used on top of it. The Avalokitesvara Bodhisattva mural was confirmed to belong to a category similar to the soil-made buddhist mural paintings of Joseon Dynasty. However, it shows characteristics such as a high content of fine sand in the finishing layer and overlapping over other colors. Such material and structural characteristics can constitute important information for future mural conservation status diagnoses and conservation treatment plans.

The flora of vascular plants in Geojedo revealed to be 550 taxa based on only the voucher specimens to be collected. It comprise 108 families, 341 genera, 478 species, 69 varieties and 3 forms respectively. Among them, 13 taxa of Korean endemics and 8 taxa of rare and endangered plants were investigated in addition to 75 taxa of specially designated plants announced by the Ministry of Environment. Furthermore, 36 taxa of induced and naturalized plants were also observed in this area. One of the characteristics of forest vegetation is the broadly occupation of Pinus thunbergii on whole area of Geojedo. Although it's well condition and conservation status, the destruction area of vegetation was rapidly increasing by the industrial development, the deforestation and the tramp as well as by the basic disturbances of human beings. Therefore, more active and positive conservation strategy such as expansion of conservation area should be prepared rapidly by the results of long-term monitoring studies.
