Purposes of this study were to provide the basic information for the management policy for more preserve and refreshing Gusumok-big and old tree. Fundamental directions for the protection and application of Gusumok were suggested by comparing and analyzing present conditions and remnant forms of Gusumok as preserved tree in Kyung-ju and its function and the role of Gusumok according to the civilization and diference between past and present. The main results of the study are as follows ; There are 121 Gusumok which designated as a preserved tree in Kyung-ju. It is distributed all over the Kyung-ju city uniformly and located in the enterance or the center of a village having high interests of most of residents. in the course of a civilzation, the percintage of a loss of an urban Gusumok is higher than that of a rural Gusumok and its function is also changed so much. A modern function of Gusumok can be divided into a positive and negative one. A positive function is the offer of amenity and the place of receation, formation of culture and ragulation of micro climate. A negative function is of psycholosical and functional reversed function. having a close relation with our life, Gusumok offers an amenity place to our life to make us feel soft and comfortable as well as developes the quality of our life. Gusumok has an important meaning in mordern society in that it contibutes to our village being better to live by having a historical meaning and creating a symbolic culture and history.

We tried to analyze qualitatively a total of 110 the research papers which were related domestic ecological restoration technologies about 15 years through semantic network analysis in social network analysis. In order to understand the research trends of ecological restoration technologies, we analyzed the degree centrality and betweenness centrality of the Stream/Wetland, Slope, Soil/Others fields selected as Word Cloud. As a result, ecological restoration technologies have been changed. They were focused on the restoration of species or their habitats in the past. However, they have been evolved into the detailed systems to respond in unpredictable natural disasters and climate change, high-resolution image implementation technology to accurately grasp the practical environment and methods related to environmental restoration for human in urban ecosystem. In the future, investment and technology for the ecosystem restoration field will be continuously demanded for the symbiosis of human beings and species in the damaged ecosystem. Therefore, the research trend of ecological restoration technologies should be provided as reliable guidelines when decision makers establish the policy direction or when researchers select their subjects.

The purpose of the study is to analyze the effect of urbanization, the degree of development in urban scale and the comparative analysis of landuse change in order to construct the important basic data for establishing development direction and characterizing each city. To analyze the urban growth patterns a land cover classification using Landsat TM data was performed : 1987 and 1997 for the change detection of each land cover. The results of this study demonstrates that urban areas increased on while forest areas had decreased all over the Korean cities. Especially, in case of the analysis on landuse conversion rate, we found out that the forest areas was first changed into agricultural areas, then it is consequently developed into urban areas in most rural areas. This study concludes that the insufficiency of the number of knowledged officials in the local administration and a government official in one's charge, tight financial conditions and absence of recognition of cities' characteristics, urban development following unrefined development patterns, inappropriate urban planning and policy of metropolitan cities and the negligence of peculiar development patterns of each city.

Seowons were first established during the Koryo Dynasty and contain primate shrines for the service of ancestors and ancient sages. Seowons were located in a scenic or rural place some distance from a residential area. The direct motive for building the Seowon came from the need for transcendental concealment and evasive retirement which developed as a result of oppression of scholars The indirect motivations were the development of loaming in an idyllic natural settings and the creation of a beautiful natural environment. he purpose of tai study is to investigate the characteristics and transformation process of the location of Seowon in the Chosen dynasty. The results of this research are summarized as fellows : 1. Seowons were in hilly areas with good geographical features including a nice view of the mountains and waters. Beowons were also built on the relation place of an ancient sage and of destroyed Buddist temples. 2. The location patterns of seowon in the Choson dynasty underwent three stages with the change of time Political and social phenomena influenced the transformation of the location patterns Research in this area is at an early stage. The present study was confined to an examination of 7he characteristics and transformation process of the location of seowons. However, it is hoped that this study will offer meaningful guide for further research.

Soil hydraulic properties such as hydraulic conductivity or water retention which are costly to measure can be indirectly generated by soil pedotransfer function (PTF) using easily obtainable soil data. The field soil structure description which is routinely recorded could also be used in PTF as an input to reduce the uncertainty. The purposes of this study were to use qualitative morphological soil structure descriptions and soil structural index into PTF and to evaluate their contribution in the prediction of soil hydraulic properties. We transformed categorical morphological descriptions of soil structure into quantitative values using categorical principal component analysis (CATPCA). This approach was tested with a large data set from the US National Pedon Characterization database with the aid of a categorical regression tree analysis. Six different PTFs were used to predict the saturated hydraulic conductivity and those results were averaged to quantify the uncertainty. Quantified morphological description was successively used in multiple linear regression approach to predict the averaged ensemble saturated conductivity. The selected stepwise regression model with only the transformed morphological variables and structural index as predictors predicted the $K_{sat}$ with $r^2$ = 0.48 (p = 0.018), indicating the feasibility of CATPCA approach. In a regression tree analysis, soil structure index and soil texture turned out to be important factors in the prediction of the hydraulic properties. Among structural descriptions size class turned out to be an important grouping parameter in the regression tree. Bulk density, clay content, W33 and structural index explained clusters selected by a two step clustering technique, implying the morphologically described soil structural features are closely related to soil physical as well as hydraulic properties. Although this study provided relatively new method which related soil structure description to soil structure index, the same approach should be tested using a datasets containing the actual measurement of hydraulic properties. More insight on the predictive power of soil structure index to estimate hydraulic properties would be achieved by considering measured the saturated hydraulic conductivity and the soil water retention.

This research is concerned with a comparative cognition of environmental issues in the countryside between socio-cultural groups. Environmental issues have been con연nod to litter, soil, sewage, wild life, noise, landscape, air, housing development, waste land and pesticides. Socio-cultural groups consisted of urban and countryside people who live in Korea and UK. The method of this study depended upon a standard questionnaire with a semantic scale. The cognition of Korean and British people are significantly different in every respect(p =.0001)except air issues. There is a significant similarity between Korean groups in 10 environmental issues(p > .03). Both Korean groups have generally recognized that their countryside environment has faced serious problems to be solved while British groups have not recognized serious problems in their countryside compared to the Korean groups. To both Korean and British groups the most worrying amongst the 10 environmental issues is the litter problem. In particular, there is a significant difference between British groups in soils(p = .0001), wildlife(p = .0009), air(p = .0001) and waste land(p = .0027). The existing policies (or countryside environment in Korea should be completely reconsidered and in Britain policies towards soils, wild life, air and waste land need to be reviewed. From the results it can be seen that cognition to countryside environment undergoes more cultural influences rather than social ones.

가로정원은 서울시 가로환경 개선 사업의 일환으로, 보행자들에게 심미적 만족과 심리적 안정감을 제공하기 위한 휴식공간으로 설치되었다. 본 연구에서는 실제 가로정원이 이용자의 심리적 향상을 돕는지 고찰하기 위해, 가로정원과 이에 상응하는 비교대상지를 선정하여 설문조사를 실시하고, 결과를 비교하였다. 서울시에 위치한 총 9개의 가로정원 중 강남대로, 디지털로, 테헤란로에 설치된 가로정원을 대상지로 선택하였으며, 비교대상지로는 동일 대로상에 위치하며 물리적 환경이 유사하나 가로정원 사업이 시행되지 않은 3개의 장소를 선정하였다. 설문은 주의회복이론(Attention Restoration Theory: ART)을 근거, '매력감(Fascination), '벗어남(Being away)', '짜임새(Coherence)', '규모(Scope)'를 중심으로 구성된 회복환경지각척도-11(Perceived Restorativeness Scale-11) 질문과, 심리적 회복을 유도한 설계 요소를 묻는 질문으로 구성하였고, 요인분석, 신뢰도 분석, 독립표본 t-검정을 이용하여 분석하였다. 분석 결과, 가로정원은 이용자들의 심리적 회복에 비교적 긍정적 효과를 미치며, 특히 이용자들에게 매력감과 흥미로움을 부여한다고 나타났다. 그러나 가로정원은 이용자들에게 고단한 현실에서 벗어나는 듯한 느낌을 주지 못하여 심리적 향상효과의 한계를 드러냈다. 심리적 회복효과를 유도한 가로정원의 물리적 요소는 나무벤치, 나무, 꽃으로 나타나, 자연적인 요소가 인공적 요소보다 심리적 회복에 긍정적 영향을 준다는 심리회복 이론에 부합하였다. 본 연구의 결과는 향후 가로정원 사업을 추진함에 있어 계획 및 설계 가이드라인 개발에 기여할 것으로 기대된다.

The objective of this paper is to investigate the development of Silhak as a Korean epistemology, to investigate the implications of Silhak in Korean society, and to discover further environmental implications. The main discussion of this paper concerns with the epistemology of environmental philosophy. Epistemology is based on the justification of certain knowledge and social philosophy. Epistemology, from the Greek words episteme (knowledge) and logos (word/ speech) is the branch of philosophy concerned with theories of the sources, nature, and limits of knowledge. Since the seventeenth century, epistemology has been one of the fundamental themes of philosophers, who were necessarily obliged to coordinate the theory of knowledge with the development of scientific thought. It is a general belief that Western ideology is substantially embedded in Eastern ideology due to physical and metaphysical colonial involvement. We argue that ecological crisis may be resulted from western epistemological mechanical view, thus we suggests a Korean epistemology as an alternative. In this paper, we seek possibility of epistemological alternative of nature in the Korean traditional epistemology incorporating the epistemology of Sung confucianism and The Silhak.

This study was conducted to understand the community characteristics of benthic macroinvertebrates according to Growth Environment at 6 Palustrine Wetlands in a rural area. As growth environment factors, size, water depth, water inlet and water outlet, land-use and water environment was analyzed. Two years' quantitative collection of benthic macroinvertebrate was carried out, and it executed community analysis and ESB index calculation and also carried out twinspan, MDS and correlation analysis. As a result, the collected benthic macroinvertebrate was 1254 individuals with 3 Phylums, 6 Classes, 14 Orders, 35 Families, 52 Genera and 61 Species. Odonata and Coenagreionidae had the highest species and individuals. Dominance Index was 0.252~0.698, Diversity Index was 1.661~2.902, Evenness Index was 0.414~0.724, and Species Richness Index was 1.990~6.224. As a result of community analysis, when correlation analysis was executed, Dominance Index had the opposite tendency with Diversity Index and Evenness Index, which had the same tendency with the previous studies. When ESB Index was calculated, Grade 2 (polluted) had the highest species with 48 species (78.7%). It is determined from the Environmental quality evaluation and saprobity evaluation result according to ESB index that there is a need to revise environmental evaluation system more specifically. As a result of MDS analysis, the subject spots A and D had the highest similarity, and the subject spot E and D had a relatively high similarity. The life environment that is the closest related with species diversity is estimated by the land-use. As for number of Individual, it seems to have the closest relation with inlet, which is to be determined as a characteristics of Palustrine Wetland. Through such investigation, this study is expected to be utilized for various types of habitats including ecological pond and to be utilized for the increase of species diversity in rural areas.
