The purpose of this study is to understand what kind of effects a local residents’ participation on a local environmental problem has on the Environmental consciousness of the resident, and on the local community. I (researcher) employed qualitative research methods on the residents' environmental movement, which claimed to preserve the Sung Mi Mountain from the Seoul City Hall's plan of the water reservoir construction. I tried to understand the participation motivation and participating actions, and also the changes and effects the participation brought at both a personal, and community level. The data were gathered by means of in-depth interview with the local residents and unstructured questionnaire. At first, through the residents' environmental movement, the participants acquired a growth in environmental consciousness. For example, they obtained better understanding of the environment, change of attitude to environment, and participation function. Secondly, it is meaningful that a local tie intervened by the environment, enforced self-governing, and shows how community sentiment plays an important role for local community organization. Moreover, the environmental movement contributed to developing a ‘culture for participation’. In conclusion, participating in a local environmental problem can be an integration of learning and practice and also leads to reflective thinking about the relationship not only between human beings and nature, but also among human beings. In addition, it can buildup a systemic cooperation for local problem-solving and the ability to make an alternative culture in the community. These are the significances of the local environmental problem-participation on the environmental education.

Waste disposal problem is one of the most important social welfare indicators in urban area, because the volume of waste generated from urban area is remarkable. So far most waste of Seoul has been disposed at landfills. However, this landifill disposal method is confronted with several difficulties in recent. As public concern on environmental problem increases and autonomy system is settled down, local community people of the landfills refuse to receive the waste produced other places any more. It brought reginal confliction problem between waste sending and receiving by refusing to accept waste from certain region. Furthermore, it is difficult to find another place to fill up the waste, while the existing landfiis is reached at the limit in the near future. In terms of environmental aspects landfill method is not the best way to dispose waste. It contaminates the soil and ground/underground water by leaking water containing many serious pollutants as well as offensive oder. In terms of equity, this waste disposal method is not fair. Environmental pollution causes damage to residence near to the landfills, while the waste produced other places. In order to satisfy the equity aspect, the waste generated a region should be disposed within the region. Incineration of Waste has been provided as the alternative. Government plans to construct waste incinerator in every anatomy, so the waste produced by local community is disposed within their local autonomous area. However, the location decision is not easy, since waste incinerator is one of the facilities to the community people. We can not apply the existing location models for this problem, because they show strong NIMBY phenomenon for the location. The location of waste incinerator should be determined very carefully with consideration of various location factors and criteria. This study proposes a methodology for determining the location of the waste incinerators by utilizing GIS, which is a power research tool for location decision where various geographical factors related. We drive the location factors which should be considered in the determination of waste incinerators. They involve environmental, socio-economic, and institutional factors. In first, we eliminate the area which is located within the environmental location criteria such as slope, fault line, distance to river, and then eliminate ares which is conflict with the social and institutional criteria.

In this paper, a hybridization of Evolutionary Strategy (ES) and a Two-Phase Neural Network(TPNN) is applied to the optimal environmental and economic operation. As the evolutionary computation, ES is to search for the global optimum based on natural selection and genetics but it shows a defect of reducing the convergence rate in the latter part of search, and often does not search the exact solution. Also, neural network theory as a local search technique can be used to search a more exact solution. But it also has the defect that a solution frequently sticks to the local region. So, new algorithm is presented as hybrid methods by combining merits of two methods. The hybrid algorithm has been tested on Emission Constrained Economic Dispatch (ECED) problem and Weighted Emission Economic Dispatch (WEED) problem for optimal environmental and economic operation. The result indicated that the hybrid approach can outperform the other computational efficiency and accuracy.

Restricted by time and space, formal environmental education has a limit in accommodating fast changing socal phenomena and quickly spreading environmental problems. Therefore, to carry out more efficiently the environmental education for middle and high school students, this study is intended to search for a way to establish a network of formal and nonformal environmental education. More than 80% of civil environmental organizations replied they agree to establish a network of environmental education. As for the establishment of a network, they preferred the establishment in which middle and high school, civil environmental organizations, government, the environment-related departments of the universities. They preferred ‘civil environmental organizations’ for the operator, ‘local municipal or provincial level for the scale, ‘direct personal relations’ for the interchange method. To establish a network, they replied that ‘funding’, ‘specialists in environmental education’, ‘staff to proceed educations’, ‘reform of law and systems’ are required. They also preferred ‘funding from government budget’ for a way to fund a network. We can draw the following conclusions from the survey, We need a training program for environmental education staff not to make those educational programs by civil environmental organizations temporary Also, more studies should be done to establish more organized network of environmental education and nonformal environmental education by civil environmental organizations. Environmental problem varies depending on the local characteristics, and thus environmental education should be carried out locally at the network center for environmental education. Besides, local self-governing bodies should support it administratively and financially.

Elliptical tubes may buckle in an elastic local buckling failure mode under uniform compression. Previous analyses of the local buckling of these members have assumed that the cross-section is hollow, but it is well-known that the local buckling capacity of thin-walled closed sections may be increased by filling them with a rigid medium such as concrete. In many applications, the medium many not necessarily be rigid, and the infill can be considered to be an elastic material which interacts with the buckling of the elliptical tube that surrounds it. This paper uses an energy-based technique to model the buckling of a thin-walled elliptical tube containing an elastic infill, which elucidates the physics of the buckling phenomenon from an engineering mechanics basis, in deference to a less generic finite element approach to the buckling problem. It makes use of the observation that the local buckling in an elliptical tube is localised with respect to the contour of the ellipse in its cross-section, with the localisation being at the region of lowest curvature. The formulation in the paper is algebraic and it leads to solutions that can be determined by implementing simple numerical solution techniques. A further extension of this formulation to a stiffness approach with multiple degrees of buckling freedom is described, and it is shown that using the simple one degree of freedom representation is sufficiently accurate for determining the elastic local buckling coefficient.
