The purpose of this study was to investigate the effect of the experience-based ecology-environmental STEAM education on ecological sensitivity of elementary students. The research subjects were 62 third graders of S elementary school located in Incheon. They were divided into the experimental group of 33 students and the comparative group of 29 students. The experimental group was provided the educational program with the experience-based ecology-environmental STEAM education. The comparative group was provided the theoretical and ecological self activity program based on the textbook. The results of this study can be summarized as follows; First, the experience-based ecology-environmental STEAM education had a meaningful effect on improvement of ecological sensitivity. Second, we found that access to the ecological environment education is important in all subjects, not in education that is biased toward. Third, in ecological environment education, experience-oriented education methods are more meaningful than indirect experiences trapped in textbooks. Fourth, ecological environment education can contribute to the improvement of ecological sensitivity as well as the intellectual aspect of ecology and environmental science. In conclusion, it was found that the ecological environment program should be conducted with activities of experience.

Identifying the distribution of species and specific factors related to it is very important because it is habitat conservation that is greatly linked not only to ecological research but also to human health. After all, protecting each one's habitat will protect wildlife and further maintain a healthy ecosystem. Therefore, in this study, data were collected, compared, and analyzed through existing studies and field-oriented surveys. The results of the survey confirmed high species diversity in agricultural areas and forest areas that can reduce moisture supply and moisture loss, and the non-segmental environment, that is, ecological connectivity, was largely influenced by amphibian species diversity. It was confirmed that the non-fragmented environment, that is, ecological connectivity, was greatly affected by amphibian species diversity. In addition, the three factors that affect amphibian survival are: It was identified as the effect of not establishing a buffer space, the effect on the ecological transformation around the habitat during the summer rainy season, and the effect on the disconnected ecological environment.

The main purpose of this study is to analyze the differences of accompanying with environment interpreter in the ecological parks, and providing fundamental knowlege on the effective management method of the ecological parks by reviewing the effects of accompanying environmental parks in the ecological parks. We had done a field experimental design in the Gil-Dong ecological park, and evaluated the differences in the education effects, used types and satisfaction by the educational types - one is control groups, i.e., accompanying without environment interpreter and the other is treatment groups, ie., accompanying with environment interpreter through questionnaire survey and observation survey. The results of study are as follows; 1) In the respect of the effect of knowledge conveyance of the environmental interpreter, there appears higher educational effects of environment and ecology to the visitors of Gil-dong ecological park with an environment interpreter. 2) Accompanying with environment interpreter made the visitors reduce the depreciative behavior but no difference at environmental attitude and satisfaction. This results provide us the effectiveness of the environment interpreters. And more theoretical study is required in the future research.

This study examined four ecological systems, namely individual, family, school, and media environments. A series of moderator analyses were conducted to examine variations in effect size estimates across the study characteristics. The current study estimated that the effect size results were gleaned from 360 primary studies, including 90 journal articles and 270 thesis/dissertations, published between 2011 and 2022. The current meta-analysis results supported the ecological framework. That is, the impact of each ecological system on the development of positive and negative peer relationships varies depending on age groups and protective-risk factors. Specifically, for positive peer relationships, the largest effect size of the protective factor was found at the individual level for young and school- aged children, but at the school level for adolescents. Regarding the risk factors for positive peer relationships, the media was the ecological system with the strongest effect size for both young children and adolescents, while the individual-level demonstrating the strongest effect for school-aged children. Results from this meta-analysis allow us to identify some vital intervention areas in terms of healthy peer-relationship development, which should be of considerable interest to the educators and policymakers who are responsible for assessing and intervening with at-risk young children, school-aged children, and adolescents. From a practical standpoint, the current meta-analysis results are expected to contribute to developing effective prevention initiatives by targeting specific protective and risk factors for peer relationship development on the ecological system level.

The purpose of this study is to suggest an environmentally friendly energy system of ecological architecture, with the reference to foreign cases, judge feasibility of it. The ecological architecture is very similar to the natural ecosystem. There is growing international scientific consensus that human activities are having a discernible effect on the global climate. Therefore, with a precise understanding of the concept of ecological approach and concrete perception of the necessity it, an establishment of planning which recognizes the ecological architecture as a organism a same time, ensures diversity, stability and cycling stemmed from the ecosystem to various activities through a ecological structure shall bring the introduction of substantial ecological architecture into domestic realm. As a result, in this Age of industrial science, We are proposing useful materials and suggestion regarding the ecological architecture planning of korean cities, by preestimating the characteristics of a city heading toward the Age of the new ecological environment.

Textile and pigment wastewater samples collected from an industrial complex showed toxic effect on Daphnia magna. For textile wastewater, 48 h acute toxicity of effluent was not detected while toxic unit (TU) of influent was 1.79. The toxicity of influent was completely disappeared by gamma-ray treatment at 10 kGy or by suspended solids (SS) removal. In case of pigment wastewater, both influent and effluent were toxic to D. magna though the effluent satisfied current water quality standards. Gamma-ray treatment had little effect on the toxicity reduction of pigment wastewater since the toxicity was mainly caused by metal ions, in particular, Cr(VI). This work suggests the bioassay technique for monitoring adverse effects of wastewater should be introduced, and also shows the usefulness of gamma-rays as an advanced treatment technique for textile wastewater.

Ecological restoration is an ecological technology that diagnoses problematic ecological spaces and restores the damaged ecosystem to a healthy appearance similar to its original appearance based on reference information obtained by analyzing intact nature. To achieve successful restoration, the project must be carried out in respect of a series of procedures. However, in Korea, restoration projects are usually actively promoted regardless of diagnostic evaluation, which wastes cost and energy, and the effect is not significant. As the reference information is not utilized, ecological restoration to return the damaged nature makes features different greatly from the appearance of nature, causing another damage. As the restoration effect is not evaluated, it is impossible to determine whether it is successful or not, and as a result, even if the project continues, there is no development and no effect. However, advanced societies have not only made academic progress by respecting these procedures but also have great economic effects along with the improvement of environmental conditions as ecological restoration has become an industry. Therefore, the international society recognizes ecological restoration as an important means of solving environmental problems at the global level, including climate change, and international organizations are actively promoting projects to treat the injured planet. However, most of the restoration projects promoted in Korea were evaluated below the level as a result of the evaluation of the effect. Nevertheless, those who have led low-quality projects are blocking plans to establish ecological restoration as a new industry that can contribute significantly to improving these levels, and thus the problem is expected to worsen. To solve this problem, it is necessary to filter out defective businesses by introducing a strict and correct project evaluation system by dividing it into before and after. Furthermore, it is necessary to establish ecological restoration as an industry and leave the process in the principles of the market.

In view of the problem of the invalidity of the incentive mechanism of the ecological subsidies, which is due to the information asymmetry between the government's supervision and the enterprise endeavor to fulfill their ecological responsibilities, this paper attempts to analyze the supervision of ecological subsidies based on the Principal-agent Model. Two conclusions are drawn: firstly, the government's supervision regarding the effect of the enterprises' fulfilling the ecological responsibilities can significantly reduce the information asymmetry; secondly, the government's incentive strength and the enterprises' endeavor level of fulfilling the ecological responsibilities are both improving the surveillance dynamics. Here is the suggestion: with the increasing of the surveillance dynamics of the government and the transparency of the enterprises' fulfilling the ecological responsibilities, the government should meanwhile increase the subsidies incentive strength, therefore, to promote the effort level of the enterprises' fulfilling the ecological responsibilities to approach to the Pareto optimal value.
