Ecological and ecosystem database is becoming very necessary to understand origins and relationship between human and nature and also to minimize disturbance caused by human activities. An ecological information portal can play important roles as a computing system to collect knowledge, distributed research findings and separated data from researchers. In this study, we designed and developed ecological information portal service (EcoBank 1.0) for collecting and providing ecological information for diverse classes of stakeholders. To reach the goal, we had reviewed related and comparable ecological database portals to design conceptual structure of EcoBank system including database management framework. Then, we developed some functions of ecosystem analysis for each stake-holders (researchers, general public and policy makers). As a result of this study, we successfully designed of EcoBank system covering the functions of Digital Object Identifier(DOI) publishing and data quality management process. Also, we (1) applied ecological indices for calculating biodiversity by administrative boundary for policy makers, (2) provided statistical information of econature map for general public and distribution characteristics of species for researchers. To make a successful establishment of EcoBank, we have to collect and build up related database and offer various and reliable ecological data consistently. We expect that the successful construction of EcoBank will help not only to accomplish sustainable development goals but also to raise the welfare of ecosystem in Korea.

The purpose of this study was to explore visitors' experiences based on two different types of ecological sites: natural and artificial ecological sites. Specifically, this study aimed to analyze the differences in the perceived experiences and satisfaction according to the perception of the visitors to the ecological sites. First, the analysis of measurement factors of visitor experience perception identified four factors such as ecological experience, environment friendliness, sociality, and relaxation. The comparison of perception according to the factor of visitor experience showed that there were significant differences between natural and artificial ecological sites and that the perceived visitor experience was generally higher in the natural ecological sites. The result of the analysis of the influence of the perceived visitor experience to ecological sites on visitor experience showed the relaxation had the largest influence for both natural and artificial ecological sites. The ecological experience and environmental friendliness also had a significant impact on visitor satisfaction in the natural ecological sites and artificial ecological sites, respectively. This paper also discussed the implications for planning and management issues at ecological sites.

The purpose of this study is to suggest improvement of certification standards of environment friendly architecture in ecological environment field by surveying and analyzing actual status of actual certification schools of environment friendly architecture per ecological environment elements through extracting ecological environment elements which is possible to analyze in quantity certification standards of environment friendly architecture. As contents of the study, first, certification as an examination on certification system of environment friendly architecture, summary of certification system of environment friendly architecture, ecological environment elements which is possible for quantitative analysis of ecological environment certification standards were extracted. Second, actual status of ecological environment elements per school grade, region, and population increase by collecting actual data of certification schools of environment friendly architecture. Third, using analysis data of ecological environment elements, ecological area ratio of certification schools of environment friendly architecture per weighted values of space types was calculated and the results were analyzed as the follows. (1) In case of preliminary certification out of total objects of investigation schools was average 34.06% but in this case of certification, it was reduced to 33.07%. However, it is difficult to make judgment as actual evidence data since ecological area ratio of actual preliminary certification is data based on drawing planes. Therefore, in case of this certification, elementary schools was investigated at average 33.11%, middle schools 34.81%, and high schools 31.28% and middle school showed the highest relatively. (2) Besides, average composition ratio of ecological area ratio was 63.04% in case of this certification regardless of school grade and region and it was analyzed that about 70% of ecological area ratio is composed of the natural based green area including pure natural based green land and 6.89% of ecological learning institute.

Baiyangdian Lake, the largest freshwater lake in North China, is known as 'Pearl of North China' and 'kidney of North China' fur its abundant products and multiple ecological services. However, from the 1970s, due to the ever-increasing discharge of polluted water from upstream rivers, it has been severely polluted. Sediment Investigation and analysis were conducted on contents of heavy metal (Cu, Zn, Cd and Pb) from Baiyangdian Lake in June 2004. Results showed that pollution situation at downriver regions are more serious than that of upstream regions. The seriously polluted spots are access of Fuhe River, original wastewater reservoir of Tanghe River, densely populated Chunshui Village and Wangjiazhai Village. By using method of the potential ecological risk assessment, the heavy metal evaluation of polluted sediment has been conducted. The results showed that the contents of Cd and Pb were very high in sediment of Baiyangdian Lake. There were extremely stronger ecological risk for Cd and slight- medium ecological risk for Pd. According to the current situation of Baiyangdian Lake, countermeasures and suggestions have been put forward.

To the best of our knowledge, this is the first report on thermophilic fungi isolated in Korea. Three species of thermophiles were isolated from compost and were identified as Myriococcum thermophilum, Thermoascus aurantiacus, and Thermomyces lanuginosus. They can grow at temperatures above $50^{\circ}C$ and produce high levels of cellulolytic and xylanolytic enzymes at high temperatures. Notably, the considerable thermostability of the endo-glucanase produced by T. aurantiacus has made the fungus an attractive source of industrial enzymes.

The object of this study is the introduction and the application of Ecological Footprint(EF) for sustainability of regional people activities. It is a tool for the evaluation of specific projects through various lifestyles or consumption to area of broad policy and budgets. But in Korea there is no assessment for consumption level of human activities by EF. Therefore this study try to analyse ecologically productive land for human activities of Cheju-island in order to assess the sustainability in Cheju and compares with another industrized countries. We analyze the human activities level of Cheju-island then the EF is about 0.9(ha/cap). This value is not more than another countries like Canada and United States. EF assists in choosing technologies, policies and Life Cycle Assessment(LCA) which can perform a certain task with the smallest ecological footprint. It will help society to avoid collapse and move towards sustainability and ecological efficiency.

Currently, the nature and ecosystem's destruction by human beings and science is appearing as a serious problem. The possibility of ecological aesthetics is being sought as one of operations for new society in the contemporary society that the nature and ecosystem are getting attention, The present research aims to examine the characteristics and its expression method by setting the ecological aesthetics as an alternative of the future design. The history, meaning, mental image and image of Korean traditional Space forming the balance and harmony with the Nature, etc., which are important design concepts, were deduced as the beauty of emptiness, the beauty of a gap, the beauty of harmony and the beauty of changing and the beauty of simplicity as characteristics of experiencing space. If the deduced expression is examined through a case analysis of traditional housing, the characteristics trying to unite with the Nature while seeing ecology and aesthetics as one root, which the ecological aesthetics regarding as a root. The ecological arts based on the ecological aesthetics enters inside the universal life of human beings by examining the ecological and aesthetic characteristics appearing in Korean traditional Space, and the arts will move forward in a direction that its function and role link with maintenance of total ecosystem. The space application possibility and expression characteristics of ecological aesthetics should be continuously researched.

The watersheds are functional geographical areas that integrate a variety of environmental and ecological processes and human impacts on landscapes. Geographical assessments using GIS recognize the relationship between interdependence of resources and ecological/environmental components in watersheds. They are useful methodology for viable long term natural resource management. This paper performs through the using hydrological analyses, landscape ecological analyses, remote sensing, and GIS. Indicators are items or measures that represent key components of the small watersheds, and they are developed to be evaluated. Some indicators are described that they represent watershed condition and trend as well as focus on physical, biological and chemical properties of small watershed. Also, ecological functions such as stability, resilience, and sensitivity are inferred from them. The model implemented in GIS allows to reflect the ecological and hydrological functioning of watershed. Methodology from image analysis, landscape ecological analysis, spatial interpolation, and numerical process modeling are integrated within GIS to provide assessment for eco-logical/environmental condition. Results are described from the small watershed of Gwynns Falls in Baltimore County and Baltimore City, Maryland, an area of about 66.5 square miles. The small watershed within Gwynns Falls watershed are subject to a number of land-use. But it is predominantly urban, with significantly lesser amounts of forest and agriculture. The increasing urbanization is ass-coiated with ecological/environmental impacts and citizen conflicts.

This was preliminary research to develop the mapping method for the Urban Ecological Map. This research provided preliminary evaluation model for ecological conservation. The model was applied to Mt. Kwanak in Seoul, and the Urban Ecological Map was produced and tested. The results are as follows. First, some problems were found in the legal Ecological Map ; insufficient and only qualitative criteria for evaluation of the conservation value in an urban area, and exclusion of the areas designated by other was laws. Secondly, in order to improve the evaluation criteria for Ecological Map, some missed sites should be added to the legal list of valuable sites. Those are needed for ecological restoration, conservation of wildlife habitats managed by a city government , and establishment of eco-corridor. Third, the efficient mapping process for Urban Ecological Map must have two steps. On the first step an ecological evaluation should be done based on pure conservation value. On the second one the Ecological Map for legal action control should be made. And the Analytic Hierachy Process is considered as a Helpful technique for improving the objectivity of evaluation model. Fourth, the legal action control system for Urban Ecological Map should be reviewed.
