This study analyzed and compared the number of students activities, contents scope, and organizing system of the three textbooks(A, B, and C) which had been developed and published for the 'Environment'subject in the 7th National Curriculum. The results of this study can be summarized as follows; There were differences in the size, the total number of pages and the quality of print between two groups of 'Environment'textbooks of the 6th and the 7th national curriculum. New textbooks were found bigger than the previous ones by 125%. The total number of pages increased by the average of 16.4%. A and C textbooks were composed of three parts, seven chapters, and 17 sections, whereas B textbook consisted of ten chapters and 23 sections. All of the three textbooks appeared to put an emphasis on the chapters of 'environment protection'and 'environmental problems of the Earth ' A comparative analysis on the number of data included in the three textbooks showed that almost half of data took a form of picture, averaging 48% of the total. A had 297 pictures, and 234 pictures for B, 194 pictures for C, respectively. In terms of the number of students'activities, C was found to include the largest number of activities that is 91, comparing to text A of 85, text B of 78. The number of students'activities in every content is found'environment awaiting protection', tile 'environmental problems of the earth'and'things to be done for the protection of environment'much more than any other parts. It should be noted that this study focused ell only a set of quantitative measures so that teachers are recommended to consider detailed contents that each textbook contains as well as environmental conditions of the school region.

The purpose of this study is to understand and compare the characteristics of the content organization system of three Environment textbooks currently used, and to examine its connectivity with the teaching & teaming methods included in the Environment subject part of the 7th Korean National Curriculum. For the analysis three Environment textbooks for middle school and their teacher's guide books by three companies. published(A, B, and C) The result of the taxonomic analysis showed that three Environment books had different steps to get to the lesson class unit in the way that A of six steps, B of five steps and C of seven steps. The amount of main text was different In the domains of'Human and Environment','Environmental Problems and its Counter-plan'and'Environmental Conservation'of three textbooks each. All of three textbooks had the biggest percentage in sub-domains of'Living Environment to Keep'and'Global Environmental Problem'in 'Environmental Problems and its Counter-plan'domain. Considering teaching & loaming methods all of three textbooks contained many activities as 55 in A, 66 in H and 91 in C. Among 9 teaching 8E teaming methods and others listed in the Environment subject part of the 7th Korean National Curriculum, the investigation method is most frequently used in all of three textbooks. The drama, the paly and the case study were used rarely as teaching & teaming methods in activities In the consideration of the content amount regarding academic fields, it was revealed that three textbooks overemphasized the aspect of natural sciences comparing the aspect of human & social sciences aspect as a whole. Generally the appendix section of all three textbooks were well organized to support the teaching and teaming activities in main text.

The shotcrete is a NATM technique as a major tunnel support for ground stability after tunnel excavation. Instead of a general concrete lining method, it is a trend for curtail of construction periods and reduction of construction expenses that required to use of the permanent shotcrete lining. This high-strength shotcrete is required to use as a permanent shotcrete lining. This brought out the solution of environmental pollution and harmfulness to human. Accordingly, in this study specimens for strength measurement were made to develop shotcrete possible to develop materials in early with cement mineral accelerator as NATM method construction. It was compared with existing shotcrete material, unconfined compression test, flexural strength test, antiwashout underwater test were experimented. The fish poison test was experimented to evaluate an influence of environment. As a results of the test, unconfined compressive strength and flexural strength were equivalent with 28-curing day strength of existing material. An antiwashout of research subject material was revealed excellently in antiwashout Underwater test. As a results of the fish poison, an evaluation research subject material was founded more environmentally friendly than existing shotcrete.

This exploratory study which applied environmental scanning method to analyse a change in a future society tried to diagnose a reaction ability of our education system for the change in the future society. In addition, the study tried to explore an adequate direction for Home Economics Subject to be an mandatory subject continuously toward the change in the future society. Main changes in the future society can be expected as 1) demographic change due to low birth rate and aging society, 2) an increasing threat of a human living environment due to unexpectable natural disasters and accidents, 3) a radical progress into a ubiquitous computing environment led by AI, 4) an advent of a borderless economic society and a change for jobs, 5) a change in North Korea, and so on. Our education system which mostly concentrates on education to develop constructive intelligence by halving the society and schooling as yet, however, is diagnosed as it has a paradox that can not understand an emotional competency as a target for studying. Home Economics Subject is worth as the subject that can exactly complement a blind spot of our education system which can not respond to the future society adequately. This is because Home Economics Subject has had a characteristic as a 'Subject of Life' traditionally that has dealt with an overall 'life' of human beings, and the characteristic is favorable to develop human practical intelligence. Thus, because the 'life' is the main point of Home Economics Subject, it has the characteristic as a 'Subject of Happiness' which is the most effective method to develop a tendency to appreciate, a sense of empathy, and lots of pro-social behaviors that are important capacities to seek for happiness. As Alderfer's ERG Theory is to understand human beings' behavior based on the satisfactory of human beings' hierarchical desires, it is suggested as an adequate frame for the theory to restructure the characteristic of Home Economics Subject which develops the 'capacity to seek for happiness' by focusing the 'life', into core concept and core capacity of curriculum. A follow-up study should make a connection between ERG Theory and core concept and core capacity of curriculum to explore how the theory can be reflected on Home Economics curriculum.

Today, environmental pollution and destruction due to the industrialization of our modem society have been the global issues. Although now we can lead affluent lives through science technologies and economic development, these environmental problems have resulted in striking the harmonious balance between human beings and nature and threatened human lives with abnormal weather caused by the global warming, destruction of the ozone layer, and El Nino phenomenon, acid rain, decrease in species diversity, movement of hazardous materials, and harmful waste increase. We are aware of the importance of environmental education, but in reality, it seems impossible to implement appropriate environmental education on account of our educational climate which exclusively focuses on the entrance examination. However, environmental education is the most ultimate solution for those problems in that only when students understand our environment fully and grow habits to protect it through environmental education, the present environmental problems can be solved and more serious problems that can be resulted in the future can possibly be prevented. Thus, this study has examined the effect of using image media in the environment subject on students' environmental sensitivity. According to the results, it was shown that it had positive effects on 'sensitivity of environment', 'attitudes towards environment', and 'environmental affinitive behaviors'.

The purpose of Environmental subject in the Korean school is pretty much similar to that of international organization. Because it doesn't apply the characteristics of School Education to environmental education, this school environmental education purpose needs to be discussed. The purpose of this study is to establish the reasonable purpose of school environmental education by analyzing the educational views. This study have been done through review of research literature, which usually includes references and papers on environmental education, school environmental education, educational point of view, educational purpose. It analyzed three kinds of views on education: technological view on education, initiation view on education, socialization view on education. The results are as follows: The purpose of school environmental education from technological view on education is environmental education activity itself that educates students to put the environmental preservation value into action. Initiation view on education aims at school environmental education as activities that instruct students on intellectual ability in order to develop a comprehensive view of intelligence. The purpose of environmental education in school on the basis of socialization view on education focuses on activities that authoritative teachers transmit the social value of environmental preservation to students in school.

Cardiovascular and respiratory responses of fish exposed to environmental hypoxia have on the subject of a number of investigations. Although relatively few species have been examined, generalized responses to ambient hypoxia include an elevation of blood pressure, increased systemic vascular resistance and bradycardia (Fritsche and Nilsson, 1990; Bushnell and Brill, 1991). The degree of bradycardia experienced by fish during hypoxia is highly variable and may depend upon the severity of the hypoxia and the rapidity with which it is imposed. (omitted)

Cleaner production is of substantial importance in changing the environmental approach within advanced industrialized countries. The critical principles involve fundamental understanding of diverse industrial processes, adherence to the earliest techniques of a hierarchy for reducing wastes, and utilization of an underlying thought process to achieve pollution prevention successes that are both technically feasible and cost-effective. Chemical engineering has played a major and unique role in this environmental field. Improving the sustainability of cleaner production will rest on including this subject in the curriculum of university engineering.

This study was aimed to find out ancestral environmental protection wisdom in their life style, and to teach environmental education applying its results in primary school. A dissertation survey was conducted to analyze environmental protection eco-wisdom, environmental education about traditional culture, application of indigenous knowledge in ancestral traditional culture for environmental education in the primary school, and Korean traditional culture presented in 5th grade subject courses of the 7th school curricula. In addition, a environmental education program was developed by applying wisdom of traditional life style and the strategy of environmental education utilizing the results from the above data in primary school was explored. It was found that students understand the value of environment education and are more interested in the ancestral life style, environmental protection wisdom from traditional culture. Also, students understand the ancestral thinking in environment, the wisdom of old Korean, and the importance of echo-wisdom related on traditional culture. Based on above results, the suggestions of this study are made as follows. First, by searching for more wisdom from traditional culture vigorously, it is needed that developing more teaching text combined environmental education with traditional culture through other curriculums. In addition, for this kind of teaching being used efficiently in another schools, the place and environmental teaching aid is needed.
