This paper aims at investigate factors inducing school violence from an ecological standpoint on the assumption that a correct analysis of what brings about it must be carried out in advance in order to prevent and cope with school violence, For that, an ecological heuristic model of factors related to school violence devised by Benbenishty and Astor(2005), who were greatly influenced by the ecological developmental theory of Bronfenbrenner(1979), was briefly introduced. On the basis of this model the author classified school violence factors into school-level factors, individual factors, family-level factors, and community contextual factors and examined relevant literature and preceding studies. Through this discussion a conclusion was drawn that, because school violence occurs not by one cause but by various causes including school, individual, family, community related factors, and it can be called 'a synthetic violence type', it is necessary to set up synthetic measures against these factors on a long-term basis. It also was concluded that only when schools, homes and societies free from factors inducing school violence are built, the countermeasures against school violence will be truly effective.

This purpose of this study was to investigate the influences of environmental education through ecological art education focused on music drama, on the environmental sensitivity of 5th graders in an elementary school in Seoul. A reconstructed questionnaire through Kim(2008)'s test tool was used to the effects of applying an ecological art educational program. The SPSS program was used to analyze the results. The major results of this study are as follows. First, the researcher was able to develop and apply a professor-learning model for the environmental education using the ecological art education focused on music drama by extracting and recreating environment related contents from the 5th grader curriculum. Second, this program had a positive effect on elementary students' environmental sensitivity. Third, according to qualitative results, students appear to be more concerned and interested in the environment and environmental problems in their daily lives. In conclusion, the ecological art program focused on music drama has a positive effect on increasing the environmental sensitivity of 5th graders. Therefore, more intensive research should be conducted, linking teaching and learning methods, as a follow-up activity.

Comprehensive utilization of zinc smelting iron slag not only solves environmental problems but also creates huge economic benefits. This study was conducted on the enrichment and recovery of ${\alpha}-Fe_2O_3$ from zinc smelting iron slag by superconducting HGMS technology. Several variables such as slurry flow velocity, slag concentration, magnetic field intensity and the amount of dispersing agent were tested in magnetic separation. In the experiments, obtained optimal magnetic separation parameters were 1.60 T of magnetic flux intensity, 600 mL/min of slurry flow velocity of, 15 g/L of slag concentration of, 0.10 g/L of dispersing agent. Under this condition, the content of ${\alpha}-Fe_2O_3$ was increased from 86.22% to 94.39% that can approach the Chinese national standard requirements (A level) of iron oxide red. It was concluded that using superconducting HGMS technology was an effective method for the purification of ${\alpha}-Fe_2O_3$ from zinc smelting iron slag.

The Ecological variables studied in relation to children's school adjustment were organisms(grade, sex, perceived competence, aggression and withdrawal), microsystems(parental support, marital conflict and supervision, peer victimization and perceived teacher attitude), mesosystems(family-peer relationships, family-school relationships) and the exosystem(neighborhood environment). The sample consisted of 565 fifth and sixth grade children. Instruments were the School Adjustment Scale and Index of organisms, microsystems, mesosystems, and exosystem variables. Statistics and methods used for the data analysis were Cronbach's alpha, frequency, percentage, Pearson's correlation and multiple regression. Several major results were found from the analysis. First, children's school adjustment showed positive correlations with perceived competence, parental support and supervision, perceived teacher attitude, family/peer and family/school relationships and neighborhood environment but showed negative correlations with grade, aggression, withdrawal and parental marital conflict and peer victimization. Second, the most important variable predicting child's relationship with teacher, his/her academic adjustment and satisfaction in schoolwas perceived teacher attitude. And the most important variable predicting children's peer relationships in school was perceived social competence.

Environmentally literated students and adults should be able to use and apply the basic ecological concepts when considering environmental problems and issues. Because ecology forms the foundation of environmental education, a review of the literatures on the degree of students' understanding for ecological concepts can provide useful insights for environmental educators. The purposes of this study were as follows: first, to analyse the parts connected with ecological knowledge of two environmental education books, ‘environments’(middle school) and ‘environmental science’(high school), second, to investigate the level of understanding on ecological concepts by the use of new developed instrument. The 20 most important ecological concepts from Cherrett(1989) and the important ecological concepts' lists from Hungerford and Volk(1990), Ramsey, Hungerford and Volk(1992), Volk(1993) would be recognized and endorsed by most environmental educators as concepts essential to environmental literacy, We referenced these informations and sequenced ecological knowledge as four main categories(communities, populations, ecosystem, man as a component of the nature systems). We have used it as a criterion in the analysis of teaching materials and the development of a new test instrument($\alpha$=0.81). According to the analysed results, the understanding levels for scales and relationships of communities, populations, ecosystem were high but those for individual concepts and differences were low. By the analysis of Korean High School EE book, ‘environmental science’, learning for some concepts(succession, material cycling, niche etc.) has pointed out as one of problems. Environmental educators must pay a careful attention to the concepts that showed high rates of incorrect answer and this work will contribute toward consolidating the basis of EE and help the accomplishment of the ultimate goals in EE.

Purpose: The aim of this study was to investigate prevalence and ecological characteristics of excessive television viewing among elementary school students in Seoul. Methods: Secondary data, representative sample of 11,082 subjects in Seoul was used. After prevalence of the excessive television viewing was identified by using factor analysis, 6 main factors explaining the ecological indicators was founded. After identifying prevalence of the excessive television viewing, by using factor analysis, we found 6 main factors explaining the ecological indicators. After categorizing factors into socio-psychological and lifestyle characteristics, we were investigated the odds ratio of excessive television viewing per characteristics by using multiple logistic regression. Results: The prevalence of excessive television viewing was 29.7% among the elementary school student in Seoul. The prevalence were higher in male, higher grade, and non-South of the Han River. Socio-psychological indicators which expressed excessive television viewing were annoying or bullying, scolding from teacher, depressed mode, thought for a runaway from home, an experience of diet, and negative body image. Life style indicators were a lower intake of fruit and vegetables, a higher intake of Ramyun and soft drink, a worse life style of hand washing, and wearing safety equipment. Conclusion: Lifestyle of television viewing was the comprehensive results from family, school, and society rather than a personal preference. Therefore, it is necessary to educate the hazard of excessive television viewing, to reenforce the students' health competence, to activate a safe leisure program as an alternate of television viewing, and to develop a recommendation.

In recent years, the objective information for the environmental effect of architecture will be furnished to the designer and inhabitant in order to minimize an excessive energy consumption and environmental loads by buildings. In addition, an environmental friendly architectural certification program for a residence, office, and school facilities have been operated to spread and supply environmental friendly architecture. Most of the environmental friendly architectural certification programs proposed in the country are focused on the aspect of the physical environments of architecture in its certification ranges. In the case of a foreign country, however, the certification ranges of an environmental friendly architectural certification program for the school facilities among the programs will be extended not only to the standards for architectural design, environmental aspect, and maintaining and management basis by considering the characteristics of educational effects for students but also to the curriculum, policy of environment, and roles of local community facilities by reflecting a social aspect. Therefore, this study proposes a design and evaluation method by considering an ecological element that will satisfy the requirement for educational well-being that includes not only the requirement for school facilities according to the development of a new curriculum like a space for teaching and learning but also the improvement of the quality of educational environments and the objective of an ecological school.

The purpose of the present study is to develop ecological experience learning program for the wetland so that elementary school students can recognize the significance and values of wetland and have the attitudes to protect it through their ecological experience learning, and investigate changes in elementary school students' perception for wetland. The experimental class was composed of 26 elementary school students and took the ecological experience learning. The comparison class was also composed of 26 students who took theoretical learning for wetland. It was found that knowledge and attitudes for wetland of the experimental class were significantly high not only in the knowledge area but also in the affective area than those of the comparison class. And it was found that interest and curiosity into wetland were elevated also in the results of the qualitative evaluation, suggesting that we could get the effect of ecological experience learning. Therefore, it is thought that above all, more experience learning programs for wetland are needed to develop for elementary school students' right view of nature and minds to love it by continuously finding and providing materials of experience learning like those of this research in the future.

The objectives of this research are as follows. First, to investigate methods for a national-scale land cover map based on multi-temporal classification of MODIS data and multi-spectral classification of Landsat TM data. Second, to investigate methods to p roduce ecological zone maps of Korea based on vegetation, climate, and topographic characteristics. The results of this research can be summarized as follows. First, NDVI and EVI of MODIS can be used to ecological mapping of the country by using monthly phenological characteris tics. Second, it was found that EVI is better than NDVI in terms of atmospheric correction and vegetation mapping of dense forests of the country. Third, several ecological zones of the country can be identified from the VI maps, but exact labeling requires much field works, and sufficient field data and macro-environmental data of the country. Finally, relationship between land cover types and natural environmental factors such as temperature, precipitation, elevation, and slope could be identified.
