  • Human being has extensively invaded, occupied, and used the natural environment as a consequence of the advance of civilization. Mankind has increasingly modified the environment for his own benefit. Such modification has not only caused the extinction of many other species but also, caused human being himself to confront to serious environmental problems. The recognition of this fact by human is expressed in the establishment and development of restoration ecology. This new study fold is, in fact, an "Eco-technology" directed towards healing of damages to the environment. The goal is to reestablish processes and functions in a damaged site, imitating the way of healing works that an integral natural system carries out. Ecological restoration uses different treatments and approaches according to extents of the existing damage and to the specific goal to be achieved. An ecological diagnosis is, therefore, required prior to restoration practice. The cost and efforts to achieve a proposed goal can be significantly reduced when a restoration plan is formulated upon the results of well-conducted ecological diagnosis. Under such perspectives, restoration ecology is a practical science, which aims to solve the problems of the real world based on the existing ecological principle. Furthermore, restoration ecology offers opportunities to test the ecological concepts and theories obtained by means of the former ecological studies. Human being exploited natural environment excessively for his comfort on one hand but damaged it inevitably on the other hand. Such intensive resource utilization and continuous environmental damaging will extend into the future and ultimately jeopardize the survival of humankind if no prompt action is taken. In the present situation, we must not continue such lives without any preparation. We have to cope with the environmental crises approaching near us by pursuing the ecological restoration that reduce the unnecessary use, recruit the deficient part, and strengthen the weak portion in our environment. Restoration ecology could be recognized as the ecology for the future in such viewpoints.

  • The purpose of this study is to prepare a plan for the development of an ecological audit program that can be applied to the elementary school curriculum for sustainability education. School ecological audits enable students or groups of students to identify and solve the school's environmental problems on their own, thereby fostering sustainable decision-making and attitudes. As a result of the study through literature research, an ecological audit project learning program applicable to the elementary school curriculum was developed. The developed program is aimed at 6th graders and is composed of 16 steps reflecting the procedural and ecological processes of the ecological audit. In order to settle the developed program in the school site and improve the school sustainability of the developed program, it is necessary to introduce a school environment management system that can periodically monitor the school environment, strengthen the capacity of school teachers, and provide a professional certification system outside the school. In addition, with this bottom-up policy-making system, students can expect to spread a sustainable school culture through environmental education activities.

  • This study was performed to show criteria of a National Ecological Network (NEN) for South Korea and it was a part of a study of ecological network for broad areas on national land showed by Ministry of Environment of Korea. After 1970s, many european countries presented methods and criteria not on individual protected area but on networking among many habitats. The PEEN (Pan European Ecological Network) and NATURA 2000 are results of those. In South Korea, concepts and mapping metheods of ecological network was studied but those were not applied to the whole national land because the equality and local specialities were not reflected. So, in this study, we presented the criteria composed of forest, river, wildlife and coastal evaluation items in conservation ecology and showed the mapping method which can applied to the national land. After the evaluation on land area which composed of forest, river and wildlife axis. Core areas were $30,616km^2$, buffer zone were $21,870km^2$ and each accounted for 31% and 22% of the national land. Except for Taebaeck-Gangwon region, whole region's core areas were accounted for 20~30% of it and buffer zone were accounted for 20~25% of it, so these can be applied to the national land with equality and local specialities. Forest axis and river axis were clearly linear and connected, but the wildlife axis was dispersed in point form. Therefore, to apply the NEN, a detailed habitat map is important and the interconnected implementation of forest, river, wildlife, and coastal axis is required.

  • The purpose of this research is to analyze the water quantity of the rainwater detention system based on the Planning Simulation in Residential Areas. The contents of this research consists of two main parts. The first part is to calculate the supply water quantity of the rainwater detention system and the demand water quantity of the Wonheungs' ecological park. The second part is to analyze the difference between demand and supply of water quantity, based on the Planning Simulation, in the rainwater detention system. This research will contribute to the establishment of the environment-friendly site planning methods which increase the quality of residential environment in apartment housing.

  • The quality of urban environment where large population reside is becoming more vitally important than ever. Recently the city of Seoul has launched a 'green city' program converting number of city owned lots into urban parks. In this study, we first investigate four recently opened city parks with water ponds in Seoul. This study then classify these parks according to their respective designs, particularly addressing design and environmental impacts by water features. From these exercises, we derive the following interim findings: 1. Design patterns of waterscape is changing. 2. Water in the city park is a major design feature. 3. Design methodology for city parks must be studied further.

  • The purpose of this study was to investigate the effects of visual properties on the human movement behavior experimentally and empirically using spatial analysis technique based on ecological perception theory. For the survey of choosing behaviors of heading direction in built environments, the experiment was conducted in which the subjects were made to choose moving directions in some spaces using the virtual environment simulation tool, and then comparative analysis was conducted on the interrelation between the experiment results and various visual properties in existing spatial analysis techniques based on ecological perception theory. As a result, the occlusivity of the isovist theory was found to be the most significant index in the human choice of heading direction, and the longest radial also showed somewhat significant effect on it.

  • In 1997, the environmental score (Q) corresponding the tolerance value of Korean benthic macroinvertebrate species and the related biotic score, the ecological score of benthic macroinvertebrates (ESB) were proposed; ESB was similar to Beck's biotic index or Chandler's biotic score. This study was carried out to revise the Q values of individual species and the assessment scheme of ESB based on the taxonomic performance and ecological information accumulated since then. The original ESB was renamed as TESB (total ESB), and AESB (average ESB) was newly proposed. AESB is calculated by dividing the TESB (for a given station) by the number of species present in the sample. In this study, TESB showed a positively skewed distribution, while AESB showed a negatively skewed distribution. The correlation between TESB and the concentration of $BOD_5$ was a little stronger than that of the original ESB. TESB showed a very strong correlation (correlation coefficient r = 0.98) with Margalef's species richness, of which correlation coefficient was higher than that of AESB (r = 0.85). AESB showed a strong correlation (r = -0.79) with the concentration of $BOD_5$, while TESB showed a weaker correlation (r = -0.67). Applying TESB and AESB together in an assessment of the environment may be comprehensive because the physical and chemical states of the environment can be evaluated together. AESB is less dependent on the sample size, while TESB tends to increase as the sample size increases. In the evaluation of the environment using TESB, it is necessary to standardize the methods on monitoring.

  • Ecological villages should be designed not only for simply reducing environmental impact such as energy saving and alternative energy use, resource conservation and circulation, harmony with surrounding environment and nature, but also for encouraging social contact and community activities with the residents, especially the aged people. The aim of this paper is to find the ecological and social design elements for the ecological village planning derived through case studies. The case studies are selected from the environmental Co-housings in Western America, surveyed in the years of 2008 and 2009. The results are as follows; 1. The ecological design elements, although there are some differences in size and type, were found to be basically applied in every ecological villages. 2. The community activities are actively conducted with the participation of the residents based on a variety of programs. The two main purposes of the community activities are strengthening the residents' familiarity with each other and the volunteer services to the local community where they belong.
