The purpose of this study was to provide a master plan for the establishment of a Korean National Museum of Natural History. The origin and development of the natural history and the natural history museum were surveyed by visiting not only Korean natural history museums but also foreign ones from 1987 to 2009. Based on the obtained information, the qualitative and quantitative status of Korean natural history museums was comparatively analyzed in terms of globalization. Results indicated that Korean natural history museums ranked more than 100th in the world, and the research, management, and publications were situated in a rudimentary stage. Particularly, the number of researchers within the area was too small, and the research environment was poor in its function and resources. In addition, the specialists on exhibition and education of the museums were too few to publish the research products and academic journal articles. For that matter, a strategy as the research-specimen management-publication-exhibition-education functions should be in place to operate before the construction of National Museum of Natural History begins.

In this paper, the author gave a brief review on the meaning and background involving the growth of chemical ecology. Semichemicals which might be developed as insect control techniques incorporating in IPM program were described. The relevant semichemicals were grouped under separate topics including intraspecific semiochemicals, or pheromones (sex pheromones, alarm pheromones, and epidiectic pheromones), and interspecific semiochemicals, or allelochemics (allomones of Plant origin, and kairomones favoring natural enemies). Here, the author dealt with those of practical aspects only. The prospects of chemical ecology in insect pest management were also proposed.

To develop an artificial bone substitute that is gradually degraded and replaced by the regenerated natural bone, the authors designed and produced a composite that is consisted of calcium phosphate and collagen. Human umbilical cord origin pepsin treated type I atelocollagen was used as the structural matrix, by which sintered or non-sintered carbonate apatite was encapsulated to form an inorganic-organic composite. With cross linking atelocollagen by UV ray irradiation, the resistance to both compressive and tensile strength was increased. Collagen degradation by the collagenase induced collagenolysis was also decreased.

Traditionally, the origin of the Han River has been thought as Utongsu(于筒水) and Geumgangyeon(金剛淵). As both of these places are located in Odaesan(五臺山) the $Ma{\tilde{n}}ju{\acute{s}}ri$(文殊) Holy Place, we can well assume the possibility of Buddhist influence on them. In the Buddhist understanding on the origin of the Han River, what we should first notice are 'the recognition on the water of Buddhism' and 'the recognition on the river in Indian culture.' With the reviews, we may come to see by what standpoint these could become existed, if there were Buddhist influences on the recognition of Han River's origin. Based on these Buddhist and Indo-cultural view points, the author tries to make more dearly the definition of Utongsu and Geumgangyeon that are recognized as the origin of the Han River. Through it, we can check the relation of Buddhism and Indian culture in their influence on the concepts of Utongsu and Geumgangyeon. In Indian culture, what is noticed in relation with the origin of the river is Anavatapta, in which the sacredness of the water named the 8 virtuous waters is recorded. It is the materialistic sacredness which can be compared with the sacred feature of Utongsu that "its color and taste are far greater than other waters, and so is its weight. ${\cdots}$ Its color and taste do not change even after it flows into the Han River." Furthermore, both of Anavatapta and Utongsu have the same symbolism of dragon that the highest dragon king and a divine dragon were told to live in respective lakes. This similar structure found in the recognition of two rivers' origin may become an evidence of Buddhist influence on the recognition of the Han River's origin. The recognition of the Han River's origin is based on the traditional culture. Therefore, it may be natural that there is the Buddhist culture in it. At the same time, some viewpoints of Chinese culture can be found in it. So, the traditional recognition on the Han River's origin comprises diversity and complexity of Indian and Chinese cultures together.

In the orient, ancestor's perception to natural environment was related on the change of climate. Man had been a essence of the warm blood animal, which had suited in mild climate for living and acting. The weather of hot or cold was not only comfort in human life but influences negatively on human behavior. The most people of oriental was particularly interrelated to seasonal change of climate in earlier time. Because, there are elements such as temperature, humidity and wind in the category of climate, these elements differentiated seasonal change. The main methods of perception of natural environment were observed and classified. Although these methods were in the primitive stage, these coincided the tendency of modern science. For example, confucian was recognized the law of vertical air current that warm air rised and cold air sinked. And they could classify all elements nature based on the principles of 'Yin and Yang(陰陽論)' such as male and female, the sun and moon. shade and light etc. Thus results of the observation and the classification concerned with physical environment can be utilize a wisdom for progressive life of inhabitants. It was a origin of the education in natural environment. Commonness in the viewpoint of environment in the orient if recognized the law of circulation. Buddhism, originated in india, realized that all of phenomena in the world was changed slowly through the principles of cycle(輪廻說) such as male and female, the sun and moon, shade and light etc. Thus results of the observation and the classification concerned with physical environment can be utilized a wisdom for progressive life of inhabitants. It was a origin of the education in natural environment. Commonness in the viewpoint of environment in the orient if recognized the law of circulation. Buddhism, originated in India, realized that all of phenomena in the world was changed slowly through the principles of cycle(輪廻說). For example, whole of land is shifted from young stage to old stage as the life cycle of humanbeing. The theory of karma effects(葉報設) is so signify with the good result that good one's action is reap a sweet fruit. The most environmental problem in today must realized as a consequence of men's act. Then Taoism emphasized the pure nature without the artificiality. Because complexual environment was composed of several elements, It was maintained through the artificiality. Because complexual environment was composed of several elements, It was maintained through the interaction of cause and effects. The solution of environmental problem is maintenanced the harmony between cause and effects by a philosophical concept.

In order to develop a sensitive and reliable method for the species-specific molecular markers, PCR-RFLP assay of the mitochondrial DNA(mt DNA) 12S rRNA gene was exploited for the identification of the origin of animal meat species including cattle, pig, sheep, goat, horse, deer, chicken, duck and turkey. A specific primer pairs were designed, based on the nucleotide sequences of mt 12S rRNA gene, for the amplification of the highly conserved region in the gene of the animal species using PCR-RFLP technique. mt DNA was isolated from meat samples followed by DNA amplification using PCR with the specific primers. PCR amplification produced an approximately 455 bp fragment in each of these animal meats. To distinguish pleat species, the PCR amplicons were digested with restriction endonucleases Tsp5091 and MboI, respectively, which generates distinct RFLP profiles. The DNA profiles digested with Tsp5091 allowed the clear discrimination in the mammalian meat species and the DNA profiles digested with MboI in poultry meat species. Therefore, the PCR-RFLP profiles of mt 12S rRNA gene could be very useful to identify the origin of the raw materials in the raw meats as well as the processed meat products.

The main results that can be drawn from the thematical analysis, based on 173 geographical names of Dong(洞) in Daegu city, are as follows. Firstly, the origin of the geographical name of Dong is divided into 10 groups such as natural landscape, human landscape, situation, and so on. Thematically, natural landscape is the most important factor among them. In particular, Dong-gu is such a case since Mt. Palgong and Geumho river are widely distributed around the area. Secondly, the origins of the geographical name of Dong in Jung-gu and Buk-gu are mainly concerned with human landscape and situation. Especially, Daegu-Eupseong(大邱邑城) has a great influence on the origin of the geographical name of Dong in Jung-gu. Thirdly, in 1914, the unification of administrative district established new Dongs(洞) and the geographical names of the new Dongs were made by borrowing each word from the existing geographical names of Dong. Fourthly, the geographical names of Dong in Suseong-gu and Dalseo-gu made after 1980s' were made in many cases by utilizing the existing natural landscapes. However, it is identified that Suseong field in Suseong-gu, Seongdang lake and Mt. waryong in Dalseo-gu have been recognized as the important natural landscapes. Lastly, the geographical name of Dong is commonly concerned with historical place names such as Gongsan battle in Dong-gu. It is judged that the geographical names of Dong based on Gongsan battle or a most intriguing piece of legend will make a great contribution on developing the regional tourism by storytelling.
