The purpose of this study was to clarify the effects of the environmental education system focusing on the knowledge, attitude and practice in relation to environmental education to the students in Mokpo middle school. The study is accomplished by the survey which includes a total of 268 inquiry lists sampled from four groups of the middle school, one of which composing of two middle schools having the environmental curriculum, hereafter referred as 'the case group' and the other group of two middle schools without the curriculum, hereafter referred as the 'the control group'. From the results of the average scores on the environmental knowledge, attitude and practice between the two groups, the case group showed better knowledge scores than the control group (p<0.05). The case group with environmental education were relatively high to the control group without environmental education to the attitude(p<0.05), and did not showed signifiant differences in the environmental practice. From the results of stepwise multiple regression analysis, the factor affecting the environmental knowledges was the interest in the environment problems ($R^2=0.130$), economic status, academic achievement and the necessity of environment conservations in order. The factor most affecting to environmental attitude and practice were the interest in environmental problems of the parents.

This study is aimed at the development of a comprehensive web-based partial differential equation solver (WPDES) using multidimensional finite element method, which can be operated on the basis of world wide web. Overall issues of engineering and environmental information management and facility control could be implemented using this solver. This paper describes the development technique of the model, which is first part on development of partial differential equation solver. Conventional commercial general solver of computational fluid dynamics problems were investigated. All the relevant environmental models were analyzed to develop integrated environmental management system using WPDES. The governing equations and the parameters of investigated models were analyzed and integrated. Several numerical modules were invented for each partial differential term in partial differential equation of many related modeling problems. Each module was coded in the fashion of object oriented method, and was combined independently for the overall governing equation. WPDES has unique characteristic, which can analyze the problem through the suitable combination of modules without development of additional models for each environment problem with different governing equation, main variables, and parameters.

The advancements of the society aggravate ecological problems, and it is at a point where our living environment is under a serious threat. To resolve such problems, environmental friendly design concepts are evolving through various naming conventions such as conservation of global environment, environmental symbiosis, friendly environmental, nature-friendly, environmental friendly type, green building and eco-construction. Accordingly, in this research, for the purposes of healthy living environmental construction, nature as the subject of its design and highly praised as a new design arena, floral art design theory and its functions, as well as its examples are explored. With the Information available, I was able to confirm that, in interior decorating, floral art design is used as a tool for expressing environmental friendly space, and gradually its necessity and the scope of its application have been broadened. Therefore, utilization of floral art design is to fabricate environmental friendly interior space; and it is expected as a substitute for accomplishing green amenity, and its study should continue for the years to come.

The research was conducted based on the 1012 cases questionnaire for the purpose of to evaluate the change effect of university student's consciousness and behavior before and after lecture on environmental problems. And this questionnaires were performed with self-administered by the university student who made a application for liberal arts related to environmental subjects. The results were as follows. According to the analysis results the most students responded that the most serious problem of environmental pollution before the lecture on environmental education was a genetic modified organism(3.64/4.00), but the most serious problem of environmental pollution was changed to the topic of water pollution(3.96/4.00) after the lecture on environmental problem. And also according to the analysis results dributed by gender were that boy students show a higher concerning(170%) than that of girl students(150%). The most good results obtained after lecture on environmental problem were water pollution(23.0%), air pollution(11.5%), waste material pollution(10.9%), food additives (10.0%), genetic modified organism(8.0%), endocrine disrupter(7.5%), respectively. And according to the analysis results distributed by a grade were that the concerning of a low grade(freshman, sophomore)were higher than that of a high grade(junior, senior) in the topic of water pollution, air pollution, waste material pollution. But there were high level of awareness on the topic of food additives, genetic modified organism, endocrine disrupter to the all students(freshman to senior). And according to the analysis results distributed by a major field of study were that students who major in art & athletics, liberal art and etc(public health) were show a deep concerning than that of science & engineering. Finally, the environmental education during the university class were effectively contribute to increase the awareness of the seriousness of environmental pollution problem(8.2%) and also contribute to the practical life after class also increase their consciousness of environmental problem(59.8%).

This paper suggested the improvement of marine environmental impact assessment of different types of project by analyzing the consultation on the coastal area utilization(133cases) of the coastal development project for 4years(2010-2013). According to the analysis results, the erosion protection project needs to precede the accurate analysis of erosion reasons, predict exactly possible problems and establish the systematic system to verify the effect of erosion protection by monitoring after projects. The construction projects of revetments and coastal roads have to require to sublate, examine the reliability in structures, give consideration to the problems of coastal erosion by increase of reflected waves. In addition, flooding protection projects have got to require to select the waves for evaluation items in conjunction with the effects of abnormal waves. furthermore, waterfront construction projects need to establish comprehensive and methodical space plans and reinforce the review to conserve the natural environment and conduct nature-friendly development. There are many problems inherently related to coastal development Project. To these problems, however, it is required to support the project on the side of the legislation and conduct additional studies reflecting the characteristics by sea areas and projects.

The purpose of this study is to analyze the content of environmental inquiry activities and values of elementary school students written in their reports of the Energy Environment Inquiry Activity Contest which is a unit contest of the Youth Science Festival held annually in Korea and get some ideas for the valuable way of Korean environmental education. 10 teams' reports were gathered and the locality, class study area, inquiry theme, inquiry method and values were analyzed and introduced as case studies to get some insights to teach elementary school students environmental values through inquiry activities of science subject approach. Each teams set various inquiry themes in the content domain of energy resources and earth environment conservation focusing on each team's geographical characteristics and occurring environmental problems in their local areas. There were 16 sentences representing technocentrism and 12 sentences representing ecocentrism. 5 of 10 teams showed both of technocentrism and ecocentrism in their reports. But their was only scientific knowledge without any environmental values in one team's report. Inquiry activity is a good teaching-learning method to develop environmental literacy. There should be environmental values involved as far as it is the environmental inquiry activities using environmental subject matter. The result of this study proposes that environmental educators should actively intervene for inquirers to set a stage in the whole process to search for an alternative to solve environmental problems involved in their project activities. The reason is because the environmental education in the elementary school is established to operate by the infusion way into various subjects already existed in the Korean curriculum.

Penetration problems in geomechanics are common. Usually the soil is heavily disturbed around the penetrating bodies and large deformations and distortions can occur. The simulation of the installation of displacement piles is a good example of the interest of these types of problems for geomechanics. In this paper the Material Point Method is used to overcome the difficulties associated with the simulations of problems involving large deformation and full displacement type penetration. Recent modifications of the Material Point Method known as Generalized Interpolation Material Point and the Convected Particle Domain Interpolation are also used and evaluated in some of the examples. Herein a footing submitted to large settlements is presented and simulated, together with the processes associated to a driven pile under undrained conditions. The displacements of the soil surrounding the pile are compared with those obtained by the Small Strain Path Method. In addition, the Modified Cam Clay model is implemented in a code of MPM and used to simulate the process of driving a pile in dry sand. Good and rather encouraging agreement is found between compared data.
