  • The ultimate goal of environmental education can be said to change students' consciousness and attitude of environment. From this point of view, this study has examined the definition of environment, the necessity of environmental education, the basic principles of environmental education, and significance of teachers in environmental education by surveying previous studies as theoretical background. Then, we have investigated teachers' consciousness and opinion about the real state and problems of present environmental education in schools. The result of this study is as follows. First, though most teachers are conscious of the importance of environmental education in school, they actually cannot practice it because of various preventing factors. Second, for the improvement of teacher's quality, we need studies and trainings on environmental education, Third, as we lack materials and programs necessary for the lectures on environmental education, it is impending to develop and provide it. Fourth, the content and goal of environmental education should be reconstituted and systematized so that they may conform to the viewpoint of students.

  • At both international and national levels, such as in the Rio Declaration and the EU's Fifth Environmental Action Plan, governments have committed themselves to the adoption of the precautionary principle (UNCED 1992, CEC 1992). These commitments mean that the existence of uncertainty in appraising policies and proposals for development should be acknowledged. Uncertainty arise in both the prediction of impacts and in the evaluation of their significance, particularly of those cumulative impacts which are individually insignificant but cumulatively damaging. The EC network of EIA experts, stated at their last meeting in Athens that indirect effects and the treatment of uncertainty are one of the main deficiencies of current EIA practice. Uncertainties in decision-making arise where choices have been made in the development of the policy or proposal, such as the selection of options, the justification for that choice, and the selection of different indicators to comply with different regulatory regimes. It is also likely that a weighting system for evaluating significance will have been used which may be implicit rather than explicit. Those involved in decision-making may employ different tolerances of uncertainty than members of the public, for instance over the consideration of the worst-case scenario. Possible methods for dealing with these uncertainties include scenarios, sensitivity analysis, showing points of view, decision analysis, postponing decisions and graphical methods. An understanding of the development of cumulative environmental impacts affords not only ecologic but also socio-economic investigations. Since cumulative impacts originate mainly in centres of urban or industrial development, in particular an analysis of future growth effects that might possibly be induced by certain development impacts. Not least it is seen as an matter of sustainability to connect this issue with ecological research. The serious attempt to reduce the area of uncertainty in environmental planning is a challenge and an important step towards reliable planning and sustainable development.

  • This study conducted empirical analysis of the association between the factors of GSCM corporation practice and social responsibility affecting environmental performance and organizational performance. Smart PLS 2.0 and SPSS 18.0 were used to examine a sample of 93 replies collected from corporations that had adopted GSCM. The results of hypothesis testing were as follows. First, social responsibility has a positive effect on the environmental performance of corporation complying with legal responsibility in environment related sectors. Second, internal environmental management and market environment have positive effects on the environmental performance. Third, corporations with a high level of environmental performance have high degrees of organizational performance. The results of this study are expected to have practical implications to corporations that will adopt GSCM in the near future.

  • Environmental Impact Assessment(EIA) was first formally established in the Korea in 1981. Subsequently there has been a rapid growth in EIA activity, and over one hundred fifty environmental impact statements are now published in Korea each year. Although EIA now has almost 20 years of history in the Korea, elsewhere the development of roles and practice is more recent. Development is moving apace in many countries, including the Japan and the EU Member States. Such progress has not been without its problems, and a number of the current issues in EIA-scope of the assessment, the relative roles, the quality of assessment and monitoring and auditing after decision, and so on- are highlighted. So the purpose of this article is to reform the EIA roles and process, in extending the scope of activity, and assessing effectiveness. This article suggested improving the effectiveness of project assessment, widening the scope: stretegic environmental assessment, and extending EIA to project design process, environmental monitoring and feedback system.

  • The objectives of this study were to investigate youth's nature experiences and environmental perception and to analyze the effects of nature experiences on environmental perception. The study was conducted by review of literature and survey. The data were collected from 146 youths in youth activities by random sampling. Major findings of the study were as follows: Firstly, youths who live in small city and have experiences in rural area showed higher average of rearing animal and plants experience than others and youths who are in high school and get upper academic achievement have higher travelling experience than others. Secondly, female youths were higher average of environmental conservation intention than males. Thirdly, learning experience about nature and sex variables influence on environmental conservation intension and age and residence influence on environmental practice. In conclusion, the study suggests youths should have opportunity on nature experience programs for developing environmental perception.

  • In this review, we have provided an overview of the environmental risk factors for attention deficit hyperactivity disorder (ADHD), focusing on the major environmental toxicants related to the disorder. Researchers have indicated that since the characteristics of ADHD are complex, the disorder’s etiology involves multiple genes of moderate effect interacting with environmental factors. The possible roles of prenatal and perinatal exposure have been the main focus of research on environmental risk factors for ADHD. Among environmental toxicants, we reviewed the potential effects on the development of ADHD of exposure to lead, nicotine, alcohol, polychlorinated biphenyls (PCBs), and dioxin. Further, for the each neurotoxicant, clinical prevention or intervention strategies aimed at reducing a child’s risk from environmental toxic insults have been presented.

  • In this study, the bio-phytoremediation and phytoremediation technologies were applied to the soils contaminated with total petroleum hydrocarbons (TPH) and heavy metals to evaluate the remediation efficacy from May 2012 to December 2013. Poplar (Populus bonatii Levl.) and Sun Hemp (Crotalaria juncea L.) were selected and planted in phytoremediation practice. These plants were also utilized in the bio-phytoremediation practice, with the addition of earthworm (Eisenia fetida) and petroleum-degrading bacteria (Pseudomonos sp. NKNU01). Furthermore, physiological characteristics, such as photosynthesis rate and maximal photochemical yield, of all testing plants were also measured in order to assess their health conditions and tolerance levels in adverse environment. After 20 months of remedial practice, the results showed that bio-phytoremediation practice had a higher rate of TPH removal efficacy at 30-60 cm depth soil than that of phytoremediation. However, inconsistent results were discovered while analyzing the soil at 100 cm depth. The study also showed that the removal efficiency of heavy metals was lower than that of TPH after remediation treatment. The results from test field tissue sample analysis revealed that more Zinc than Chromium was absorbed and accumulated by the tested plants. Plant height measurements of Poplar and Sun Hemp showed that there were insignificant differences of growth between the plants in remediation plots and those in the control plot. Physiological data of Poplar also suggested it has higher tolerance level toward the contaminated soils. These results indicated that the two testing plants were healthy and suitable for this remediation study.
