This study was conducted to find and explain characteristics of diverse social groups' attitudes toward nuclear power plant. 7 hypotheses were constructed and statistically tested. In order to test 7 hypotheses, both Nuclear Energy Attitude Scale and Environmental Attitude Scale were distributed and field surveyed on 839 respondents representing a diverse range of subject groups. The results showed that 6 hypotheses were statistically accepted while 1 hypothesis statistically rejected. Contrary to the first hypothesis, this test found that people in close proximity to the nuclear power plant had more positive attitudes toward nuclear power than those living in distance from the nuclear power plant. Males had more positive nuclear energy attitudes than females. Academic backgrounds were not related to nuclear energy attitudes. Environmental attitudes showed negative relationship with nuclear energy attitudes. While anti-nuclear citizen action groups had the most negative attitudes, nuclear power plant workers had the most positive attitudes among responding groups. Finally, university students majoring in nuclear engineering had more positive attitudes than those of religious studies.

Environmental education contents in science textbooks of South Korea and the United States were compared and analyzed in order to find how to develop environmental education in elementary science education. McGraw-Hill science textbooks for third to sixth grade and science textbooks of Korea based on the 2009 Revised National Curriculum and the 2007 Revised National Curriculum were analyzed and compared. The categories were educational goals, kinds of contents, distributions of contents and tense. The result showed that the environmental education goals in science textbook of Korea and United States were biased to knowledge area. The educational contents of the United States was higher 2.5 times then Korea and distributed in all areas. In quantitative distributions in Korea were biased some special areas. Tense of educational contents were almost present. Attitudes and recognition of students varies gradually over a long period of time, the contents of environmental education will be useful "evenly distributed" for all areas and school year.

This study attempted to characterize conflict frames of environmental disputes by examining twelve actual wetland permitting cases in Ohio. The participants consisted of such interested parties as applicants, technical, legal or environmental consultants to applicants, U.S.Army Corps of Engineers, U.S.Environmental Protection Agency, U.S.Fish and Wildlife Service, Ohio Environmental Protection Agency, Ohio Department of Natural Resoures, local agencies, the environmental community, and citizens who have been involved of the permitting process. The purpose of this study is to provide empirical evidence of how different perceptual frames existed in the wetland conversion disputes, and to understand different environmental conflict frames that influenced disputants' perception relating to dispute resolution. The vehicles used to collect the necessary data were three survey instruments : Open-ended questionnaires, Likert-type questionnaires, and ranking questionnaires. Forty-three subjects were contacted for open fact-to-fact interviews, 53 subject for Kikert-type mail survey and 54 subjects for ranking instrument mail survey. Analyses of survey results revealed that six different types of frames were clearly identified from all the parties involved in Ohio wetland conversion disputes. It revealed that disputants had statistically significantly different levels of perception to the frames based on the participants' role (i.e. regulator, applicant, commentor), the number of involved parties in the process, processing time and the issuance of a permit. The findings also revealed that information sharing among disputants played a significant role in the process of froming and reframing. The alternative idea, building cooperation through negotiation, was proposed to provide new insight into the resolution of the dispute.

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.

This study suggests a method for calculating the benefits of water pipe renewal based on an estimate of the water supply suspension risk. The proposed method based on five benefit items is more direct and specific than other benefit estimation methods. In addition, a methodology evaluating the economics of pipe renewal based on pipe failure rate is proposed for estimating the optimal renewal point from an economic perspective. By estimating the optimal renewal period based on a yearly benefit cost ratio per pipe in a case study area, it was possible to draft an optimal renewal plan for the subject region from an economic perspective. Compared with other methodologies, a reasonable optimal renewal period was derived from an economic point of view. The result of this study may be used to develop future water pipe renewal plans. Moreover, the proposed methodologies and results derived from this study can be applied to asset management plans.

This study was conducted to investigate the concern of the primary school teachers and the teaching situation about the environmental education through questionnaire survey on the effective environmental education. The results of questionnaire were analysed and discussed to provide the effective teaching method for the environmental education. The result of this study is as follows. 1. It was found that teachers want to teach environmental lessons as a special subject, and the content of the environmental lessons in textbook was not enough in quantity, the living waste was the most serious ploblem. Owing to the lacking in materials for the lectures on environmental education, most teachers collect the material depending on the mass communication. Also they were more interested in the environmental lessons rather than the other lessons in textbook. But because of the lacking in administrative assistance, they have difficulty in conducting the effective environmental education. 2. The teaching method of the environmental education in most primary schools was a all together-type lecture in classroom. Owing to conducting the environmental education for the knowledge than the action through the extra activity, it was difficult to expect the effect of the environmental education. Also the rate of using the reflection materials which can be improved the studying effect was very low. 3. For the effective environmental education most teachers wanted the spot learnings and the case studies and teacher education and training to get an special knowledge for environmental education. The effective evaluation method for children's environmental education is to present the results by environmental experiences and practices and to formulate a system education is organized for the effective management and activation of environmental education. 4. By practising the seasonal spot learnings, students need to change of learning method and to realize the importance of environment through own self-experiences. 5. In the future, it is desirable that researching of an environmental education is offered the effective practising teaching method which is improving the development of customs and functions, cultivation of the sense of value, ability to solve the problem, to determine the intention as well as the survey on the real situation and the consciousness about environmental education.

In the sustainable waste management, the necessity of environmental education which improves acquisition of the knowledge, attitudes and values for the environment is being emphasized to help students make environmentally desirable decision and promote responsible environmental behavior. However, the environmental education in high schools, as a whole, would be susceptible to many problems caused by tile educational administration focusing only on the college entrance examination. Therefore, this study modifies and applies a program using four teaching/learning methods (Investigation study, Internet-based learning, Field work, Issue analysis study) which deals with the sustainable waste management as the learning subject for the environmental education, and tries to find its effects on the students' environmental sensitivity and environmental conservation behavior in high schools. The main results of this study are summarized as fellows. First, the waste management program had little influence on the environmental sensitivity of experimental groups, while it had positive effect on their improvement of the environmental conservation behavior. Second, there were little meaningful effect on general environmental conservation behavior, but there were some significant results to environmental conservation behavior related to the sustainable waste management. In addition, positive results were found in ecomanagement and consumerism, whereas there were no meaningful results about in persuasion and legal action, which were sub-domains of the waste management program. Among the waste management programs, the school waste investigation study had the most positive effect on the students' recognition and solution of environmental problems as well as improvement of environmental conservation behavior. The easiest one of the four teaching/learning methods was the Internet-based learning, while the most difficult one of them was the issue analysis study. Consequently, in order to achieve the goals of the environmental education in the academic field, there has to be selected the most suitable one of the teaching/learning methods and to be applied to the class, according to the detailed objectives and loaming contents for the environmental education.

The present study numerically analyzed the dynamic behavior of 3D framed structures subject to impulsive slamming forces by violent breaking waves. The structures were modeled using multiple lumped masses for the vertical projections of each member, and the slamming forces from the breaking waves were concentrated on these lumped masses. A numerical algorithm was developed to properly incorporate the slamming forces into a dynamic analysis to numerically determine the structural responses. Then, the validity of the numerical analysis was verified using the results of an existing hydraulic experiment. The numerical and experimental results for various model structures were generally in good agreement. The uncertainties concerning the properties of the breaking waves used in the verification are also discussed here.

In this study, specific teaching methods of lecturing and improved discussion methods (combining discussion and problem-based learning) were selected and applied for each major subject and learning content area in the fields of engineering, language, and social sciences. Then, the selected teaching methods were examined to determine the most effective learning contents. Finally, in order to determine the most effective teaching methods, a survey on student satisfaction was analyzed statistically. The results showed that students preferred teaching methods that combine lectures and improved discussion methods to the traditional method of only lectures. Therefore, this research proposes the combined teaching method for each major subject and learning content area.

Recently the complexity and difficulty of the IT projects are increasing due to technological and environmental risks, resulting in the adoption of PMO(Project Management Office) onto IT project management practices, including public area projects. For example, the Korean government regulated the application of PMO onto large scale public IT projects. However, since there has been no reliable method to estimate the cost to execute PMOs, a PMO cost evaluation model to support the budget and cost planning of PMO projects is required. Thus, the purpose of this research is to develop a systematic cost evaluation model for PMO projects. We identified the dimensions that determine the PMO execution cost to be the scale of the subject project, the technical difficulty level of the subject project, and the tasks to be executed in the PMO project. Based on the determinants, the PMO execution cost model were developed from historical data and experts opinion. Upon verification, the validity of the developed model has high level of consistency compared with their experiences of real PMO project costs.
