  • The Jeongdori windbreak forests of Wando island, located between the sea and the land, are very important as ecological succession areas that protect cultivated lands and fishing villages. Among the Jeongdori windbreak forests, the rocky seashore areas are occupied by Sageretia theezans mantle community, and their inner sections by sub-tree layers such as Ligustrum japonicum and Ligustrum obtusifolium. More specifically, the inner sections of the rocky seashore areas were found to be the habitat of Ligustrum japonicum-Quercus variabilis community, Ligustrum jarponicum-Viburnum erosum community, Ligustrum japonicum-Cinnamomum japonicum community, Cinnamomum japonicum-Carpinus tschonoskii community, and Pinus densiflora-Viburnum erosum community. The average height of tree layers of the Jeongdori windbreak forests is 10.3m, and the average diameter at breath height are 30.3cm. Though the windbreak forests was artificially made, it is now virtually natural forest and deserves protection for ecological reasons. Designated as a scenic spot 3, it is always in the danger of being damaged by frequent tourist visits. So the Jeongdori windbreak forest needs to be continuous maintenance and management by the National Park Service. Considering of the precious cultural treasures of the famous pebble stones covering Gugyedeung and the naturality of the Jeongdori windbreak forests, the Jeongdori windbreak forests as a scenic spot have to designated as the national monument in future and will preserve by the Cultural Properties Administration.

  • In this study we tried to develop a biological method for evaluating environment using the potter wasps as an indicator. Wasp species in family Eumenidae, were collected from 13 locations including agricultural area using nest trap. The wasps collected were classified and selected candidate species as an environmental evaluation indicator. Seven species were collected and the Anterhynchium flavomarginatum was the most dominant species. The number of the nest of potter wasps was 12.8/m both in the non-fertilizer and the non-pesticide areas and 7.2/m in the general agricultural areas. The number of nests was 13.4/m in the location where the Degree of Green Naturality (DGN) was high (4.28) and it was 1.2/m where the DGN was low (1.00), suggesting that the index of both richness and diversity tend to increase in locations with more nests. Based on these results, A. flavomarginatum, Orancistrocerus drewseni (Saussure), Isodontia nigellus and Chalicodoma sculpturalis were selected as indicator species for the evaluation of environment including agricultural ecosystem. And a standard for grading an environment (I to IV) was made based on the occurrence, the total number of nesting and the species diversity of potter wasps.

  • In this study, I examine what is called character. It is to establish what constitutes a relationship between life, culture, and education. In addition, I try to explore the possibility of anthropology of education as an academic basis for character education by using the way of '문 질빈빈(文質彬彬)'. As a result of the study, 'character' in terms of '문(culturality)' aspect implies the qualities, the nature, the disposition, and the meaning of virtue. A 'character education' can be seen in school education as a moral consideration, considering the social context, such as the ability to live harmoniously. In terms of '질(naturality)', I will look at both the innate aspect of the character and the acquired aspect through the 'character' which is the essence of character. Character is the concept of both parties, and if it is influenced by an external environment, one can seek better ways to improve the chances of improvement through education. Furthermore, the role of education is inevitably required in order to achieve the goal of 'lesser human being' to 'better human being'. Home and school education can have a positive impact on the character. An honest mind about humanity among family members is the right character. The importance of humanity is considered as a value to be recognized and protected in our society because the logic that it protects the family by character and helps to maintain the social order influences to the legal culture tradition of the modern. Therefore, the academic approach through anthropology of education has sufficient value of trial study for exploring the relationship between character, education, and culture for teachers and learners, and is appropriate for providing an academic foundation.

  • In this study, we carried out a distribution and migration boundary lines of chum salmon (Oncorhynchus keta) in the Milyang River. We measured the total length of dead chum salmons. As a results, 40 chum salmons were found during the study period, 25 dead salmons and 15 alive individuals. The ratio of female was 64%. We verified the migration boundary lines of chum salmons based on a sighting survey until detecting a structure that chum salmons are not able to migrate upstream. We discovered that chum salmons were not able to migrate up to 13 km in a mainstream of the Milyang River and up to 12 km in the Danjang stream (a tributary of the Milayang River) from upstream of the Yerim Bridge. Therefore, our results indicate that Milyang River should improve a river connectivity by demolishing weirs that disturb chum salmon's migration or installing appropriate fishways. Also, effective legislations are needed to retain naturality in spawning ground and micro-habitats to increase the survival rate of parrs and smolts.

  • The purpose of this study is to derive political implications and to look into the establishment of new directions for the biotope mapping across the Korean territory so that such biotope mapping process could be used as a means of actual plan for natural environment preservation through the comparative study of biotope mapping methodology with that of the biotope mapping pioneer-Germany. As for research methodology, this study collected literature and data related to the biotope mapping of Korea and Germany and examined the general characteristics and inclinations about biotope mapping of both country, at a level of the national territory, federal government, provincial government, city and settlement areas. As a result of the examination, first, it was found that Germany drew up a landscape eco-type map and ecological landscape grade map throughout the nation in order to preserve and manage effectively by differential landscape eco-type unit. In contrast, Korea drew up a map on which Degree of Green Naturality and Ecological Nature Status are reflected for natural environment preservation at a nationwide unit. Secondly, the biotope mapping of German was worked centering on natural areas and their corresponding areas at German provincial government level and it drew up a Red-list by each province, while Korea has yet to carry out biotope mapping at a provincial level corresponding to Germany's. Thirdly, the biotope mapping on German cities and settlement areas includes not only big city areas but also medium & small cities and rural areas whereas Korean biotope mapping is conducted mainly centering on urban areas. In conclusion, this study suggests that the biotope mapping including natural areas and anti-natural area, not limited to city areas should be revitalized in order to be a real means of the all territory's balanced natural environment and biotope preservation & management. In addition, for this purpose, this study suggests that research on biotope pattern catalog and biotope red-list applicable to all territory should be preceded.

  • Recently planification and effort for management, assessment and discovery of geological heritagesare being increasingly demanded with institutional strategies such as geopark, as their preservation is asked socially. In this study, we discovered geological heritages in the Jeolla Province and then performed assessment of the value and grading of them and finally suggested a promising and suitable site for the National Geopark. A total of 325 geological heritages are listed on literature review and then detailed description in field and assessment of the value for selected 158 geoheritages are completed. The assessment items are categorized into intrinsic value, subsidiary value, and preservation/management part. The intrinsic value is subdivided into scientific/educational value, composed of representativeness, rarity, geodiversity, typicality, reproducibility, and particularity, and geomorphological/landscape value composed of scale, naturality (integrity), scenery (aesthetic value). Also, subsidiary value consist of 7 subsections of soil function, ecological function, tourism value, geological resource, historical value, folk tale or legend and symbolic value, and accessibility, convenient facility (infrastructure), management condition (legal protection) is evaluated in preservation/management part. The heritages in the Jeolla Province subdivided into three types: 73 geological heritages, 42 geomorphological heritages, and 42 composite heritages. Based on points acquired in intrinsic value, all geological heritages are graded Class-I to -V. As a result, numbers of geoheritage belong to Class-I (protection at world level), -II (protection at national level), -III (nationdesignated management), -IV (involved management list), -V (candidate management list) are 12, 39, 52, 34, 21, respectively. Finally, we construct database based on Arc-GIS with all informations for each geological heritage and suggest three promising and suitable sites, 'Jirisan-Seomjingang Area' and 'south coast area of Jeolla Province', for the National Geopark.

  • To select indicator insects, the abundance of which is one of the major criteria for the evaluation of agricultural environment, was designated and monitored in the three sites (Hongcheon A, B, and Yangpyeong) from 2001 to 2003. Characteristics of rice cultivation are usual cultivation with 2 or 3 times sprayed chemical agents per year in Hongcheon A site, duck cultivation with non-sprayed chemical agent, green manure and mowing in Hongcheon B site, and pond snail with non-sprayed chemical agent, green manure and mowing in Yangpyeong site. Dominant floral species are Digitaria ciliaris (Retz.) Koel., Persicaria thunbergii (Siebold & Zuccarini) H. Gross, Echinochioa crus-galli (L.) Beauvois, and Humulus scandens (Lour.) Merr. in Hongcheon A site, Digitaria ciliaris (Retz.) Koel., Persicaria thunbergii (Siebold & Zuccarini) H. Gross, and Echinochloa crus-galli (L.) Beauvois in Hongcheon B site, and Digitaria ciliaris (Retz.) Koel., Setaria viridis (L.) Beauv., and Persicaria langiseta (De Btuyn) Kitagawa in Yangpyeong site. Degree of green naturality (DGN) was higher in Hongcheon B site (2.0) and Yangpyeong site (3.6) than in Hongcheon A site (1.6). Number of species and individual of insects collected in the three sites were abundant on August and September. The species diversity was higher in Hongcheon B and Yangpyeong than in Hongcheon A. And Coleoptera was dominant in the all sites. The dominance index (DI) was the lowest, but diversify index (H'), evenness index (E) and richness index (RI) were the highest in Hongcheon B site. Based on three results, indicator insects for the evaluation of agricultural environment were selected as Dolichus halensis in Hongeheon A site, as Pheropsophus. javanus and Polionemobius mikado in Hongcheon B and Yangpyeong sites.

  • The purpose of this study is to specify the prior eco-preserve zone by establishing the eco-landscape unit on the stream corridor and evaluating the stream ecosystem in the dam basin. The fundamental ecological data was surveyed and collected through "the ecosystem project on Yongdam multipurpose dam watershed" from 2008 to 2009. The Yongdam Dam Watershed has several streams, Jujacheon, Jeongjacheon and Guryangcheon, of which the area is $930km^2$, stretching to Jinangun, Jangsugun and Mujugun Jellabukdo. In spite of being used for drinking purpose, the dam water quality and ecosystem is threatened by in-watershed pollution produced by development, golf course grounds and sports complex, etc. The landscape unit of stream corridor was zoned across by 250m, 500m, and 750m from the vicinity line of stream, which was decided to the accuracy of mapping and surveying. Types of evaluation are the Stream Corridor Evaluation(SCE) and the Vegetated Area Evaluation(VAE). In the process of SCE, several indices were analysed, fish species diversity, species peculiarity, and stream naturality. Indices for VAE were forest stand map, vegetation protection grade, species diversity and peculiarity for wild bird and mammal life. The importance of the ecological items is categorized into three levels and overlapped for specifying the prior preserve zone. The area at which legally protecting species appeared is categorized as absolute preserve area. This study might be meaningful for proposing the evaluation process of a stream corridor ecosystem, which can synthesize a lot of individual ecological surveys. We hope further research will be actively performed about the ecotope mapping which is based on a individual wildlife territory and habitats and also their relationships.

  • The rapid urbanization and increase in population due to industrialization have led to the extension of cities and the reduction in naturality as a necessity. Now, it is the biggest threat to virtuous circle of ecosystem. With the expansion of common recognition that this ecological crisis would be accompanied by the crisis of mankind, many countries all around the world are conducting researches to indicate the optimum consumption level of individual as an index in addition to cross-national environmental indicators such as ESI, EPI and SDI, by measuring environmental consumption of state, local government or individual, and comparing each region. Based on this background, this research was carried out to estimate the environmental capacity of 23 local government in Gyeongsangbuk-do. The result of EF estimation showed that EF value necessary for life per head in Gyeongsangbuk-do was 0.9534, and it showed an ecological deficit of 25.3 percent when analyzing it in consideration of the ecological capacity. Also, among the local governments in Gyeongsangbuk-do, Youngduk-gun displayed the highest EF, and Ulleung-gun displayed the lowest EF. But when analyzing the ecological deficit in consideration of the ecological capacity of each region, Gumi-city showed the greatest ecological deficit, and Youngyang-gun showed the biggest ecological capacity. The environmental capacity estimated in this study is to digitize the ecological capacity and ecological deficit of each local government in Gyeongsangbuk-do. The estimated optimum environmental capacity of each local government suggests the scale of environmental preservation and proper development and furthermore, could be used as fundamental data for persuading members of each local government when selecting a location of development facility or preservation area.

  • In order to get as ecological basic data for river restoration, vegetation investigation was conducted in natural river and analysed it synecological methods, such as ordination cluster. 29 plant communities units were identified and the major dominant plant communites were Quercus mongolica community, Pinus densiflora community, Populus davidiana community, Q. variabilis community and Prunus sargentii community. River vegetations were classified into ravine and gorge forest type and riverine softwood forest type. Ravine and gorge forest was dominanted by hardwood which located in steep slope and in high elevation, and riverine softwood forest by softwood, salix spp. Naturality was an important criterion for the selection of rivers, so many of the selected rivers are located in the upper stream and mid stream rather than the lower stream, where more human intervention is involved. Plant communities were consisted of hardwood forest(44 plots, 92%) and softwood forest(4 plot, 8%), respectively. PCA with total layer data showed 5 groups of communities: Q. mongolica community group, Prunus sargentii community group, Pinus densiflora community group, Prunus sargentii community - Pinus densiflora community group and the rest communities group. PCA with tree layer showed 3 groups: Q. mongolica community group, Prunus sargentii community group, and the rest community group. Cluster analysis also a showed a similar communities group to PCA ordination, but Magnolia sieboldii community and Prunus sargentii community were distinguished from the PCA result. From the result, it can be concluded that the plant communities of riparian be divided into hardwood and softwood forest by statistical techniques. It was appropriate to plant species such as Quercus mongolica, Pinus densiflora, Populus davidiana, Quercus variabilis and Prunus sargentii, at levee zone and high water level. And Sliax spp. were appropriate for planted plants at waterfront and low water level. The herb species to be planted on the floodplain were recommanded in the species composition co-occurred with the woody species.
