This study presents how a professional development program (PD) of K-12 teachers affects participants' use of the earth system approach and their perceptions of using the urban environment for their science teaching and lesson unit development. This study utilized mixed methods to collect and analyze the data. Eleven urban teachers' pre-post lessons (45 lessons) were analyzed quantitatively using a lesson plan analysis tool, modified by the author, and their lesson reflections were analyzed qualitatively. The findings of this study show that the PD program influences the teachers to choose more topics and content knowledge based on the earth system approach and to assess the topics and content knowledge with more appropriate methods. Specifically, the teachers use more urban environmental factors/topics in their post lesson to teach the environmental topics of urban area. However, according to the statistical analysis of pre-and postlesson plan scores, the accuracy of the earth system knowledge that participants used in their lessons did not change significantly (p<0.05) (Table 4), which means that the PD program did not affect the improvement of the teacher's content knowledge in earth system science. Implications of this study are discussed.

In May 2010, Indonesia and Norway signed a Letter of Intent on "Cooperation on Reducing Greenhouse Gas Emissions from Deforestation and Forest Degradation(REDD)." In the LoI, Norway agreed to offer Indonesia a sum of USD 1 billion with a view to encourage Indonesia to significantly contribute to the successful implementation of REDD+. On 20 May 2011, correspondingly, Indonesia announced the 2011 'Forest Moratorium' (the Presidential Instruction No. 10/2011) which was valid for the following consecutive two years. By means of the 2011 'Forest Moratorium', Indonesia aimed at significant reductions in greenhouse gas emissions from deforestation, forest degradation and peatland conversion. In so doing, it also sought to improve forest governance. Meanwhile, concerned stakeholders also raised various questions about the effectiveness of the 'Forest Moratorium'. As an extension of the 2011 'Forest Moratorium', Indonesia announced the 2013 'Forest Moratorium'(the Presidential Instruction No. 6/2013) for another two-year period on 13 May 2013. Indonesia's 'Forest Moratorium' is concerned with stakeholders at various levels, who may play a role of significant 'agent' in the process of implementing the 'Forest Moratorium'. This mechanism of the 'Forest Moratorium' should be understood in the light of forest governance. Employing stakeholder approach, therefore, this article attempts to analyze Indonesia's 'Forest Moratorium' in the light of forest governance. In this regard, it analyzes the detailed contents of the 'Forest Moratorium', the process of making the 'Forest Moratorium', current development of the Indicative Moratorium Map for suspension of new concessions on forest land, and contesting views of various stakeholders. At the same time, it also talks about how 'weak' forest governance had influence upon Indonesia's 'Forest Moratorium'. In so doing, this article consequently attempts to evaluate Indonesia's 'Forest Moratorium' and also put it into perspective in terms of improving forest governance. The 2013 'Forest Moratorium' fundamentally represents a radical policy that is designed to suspend new concessions on forest conversion for another two-year period and its detailed contents attempt to reflect on various stakeholders from related industries and environmental NGOs. However, there are challenging factors in the process of implementing the 'Forest Moratorium', that is, 'weak' forest governance and also a discrepancy between forest planning maps designated by central and regional governments. The announcement of the 2013 'Forest Moratorium', as an extension of the 2011 'Forest Moratorium', may functionally strengthen and improve Indonesia's forest governance. However, at the same time, there is a practical limit due to the fact that it is merely a Presidential Instruction that lacks legal binding.

The intent of this study is to suppose the time of engraving of Bangudae-rockgraving-picture and the change of the ancient soci-ety related to the Postglacial transgression and regression in the Ulsan Bay. Main results can be summed up as follows; 1. It is supposed that the shoreline in the maximum Postglacial transgression of the Ulsan bay has arrived to Gulhwa-Ri about 14km upstream from the present Taehwa River mouth. 2,.This transgression has occurred about 6,000-5,000 years ago. The prehistoric men around the Bangudae had hunted the whale near the inner bay From this time the people had begun to engrave pictures on the Rock of Bangudae for the ceremony and instruction of the whale hunting,. 3. Since then the shoreline had regressed and the whale hunting area had moved to distant area from the residence and the number of the captured whales had diminished. The whale hunting society had been transformed to the overland animals on the Bangudae-rockgraving- pictures had gradually increased.

The purpose of this study was to analyze the elementary school teachers＇perception toward the environment-related subjects in science education and to investigate their instructional methods in delivering the subjects in the classroom. The participants of this study were 300 elementary school teachers sampled from elementary schools in Kyung Nam Province. The findings of this study were as follows; First, more than half of the teachers surveyed showed that the environment-related units and contents in the science textbook were insufficient to the existing issues. Second, the large portion of teachers responded that the teaching materials in the textbook were insufficient to deliver the contents. Third, the largest portion of respondents replied that their preferred instructional method was a teacher-directed instruction followed by a case study approach. Fourth, in terms of the effectiveness of environmental education, both male and female teachers showed negative responses. Furthermore, male teachers were more negative than female teachers. Fifth, total means of their preference of the environment-related units was 3.13. The unit for sixth graders titled｀Environmental Pollution and Protecting Nature＇showed the highest preference, whereas the unit for fifth graders titled｀Structure and Functions of Plants＇showed the lowest preference. Sixth, there was no statistically significance in gender and their working areas. Seventh, there was statistically significant differences between male and female teachers in terms of teaching experience. In detail, the teachers with 5 to 9 teaching experience showed the lowest scores, while the teacher with more than 15 years teaching experience showed the highest scores in their perception of the units. Eighth, there was a significant difference between two groups in terms of their educational background. For example, two-year college graduates showed higher preference than four-year college graduates.

In Korean education, the health contents are scattered in various course subjects throughtout the primary and junior high school curriculum. So it is very difficult to provide systematic health education. The purpose of this study was to provide a guide for health education using health topic areas and major concepts that represent the scope of material that should be covered in health instruction. The steps used in selecting these health topic areas and major concepts were as follows: 1. A review of the literature related to health and health education was done to develop the rationale underlying this study. 2. Health topic areas basic to the growth and development characteristics of children, to human needs and to societal needs for healthful living were indentified. 3. The major concepts for each health topic area based on health sciences and children's growth and development levels were selected. 4. The major concepts selected were organized in sequence to guide health education from grade one to grade nine. The results of this study were as follows: 1. The identification of eleven health topic areas essential for health education. These include: personal habits and health healthy growth and development nutrition and health prevention of disease and disorders drugs and health mental health family life and health sex education accident prevention consumer health community health 2. The identification of the major concepts(generalizations) for each health topic area: 33 major concepts were identified as a guide in determining the health content of health education programs. These are 1) body cleaniness, 2) health of the sensory organs, 3) dental health, 4) exercise and rest, 5) growth and development, 6) body structure and function, 7) developmental tasks, 8) balanced nutrition, 9) eating habits, 10) food preparation and food storage, 11) sources of disease and disorders, 12) disease preventive behavior, 13) care during illness, 14) drug use and misuse, 15) drug addiction, 16) emotional responses, 17) human relationship, 18) self concept, 19) social adjustment, 20) health habits of the family, 21) interdependence of family members, 22) origin of life, 23) characteristics of man and woman, 24) sexual instinct, 25) safety behavior, 26) emergency measures, 27) criteria for selection of health products, 28) proper use of health information, 29) utilization of health and medical services, 30) environmental conservation, 31) environmental pollution, 32) population control, 33) function of public health services. 3.

The purpose of this study was to identify and name clusters of school health program, and to describe some of the characteristics of administrative supports. The literature, materials and public documents were analysed by the chronological events from 1945 to 1989. The result of this study is as follows : 1. A brief summary of the history of school health program was included as an introduction to the analysis of the current programs of school health. Five current school health-program clusters were identified from findings of a study of programs ; 1) Physical assessment, laboratory examination and health services for the students, 2) health insturction 3) healthful living condition(environmental health), 4) health clinic management 5) administrative supports. 2. The earliest school-based efforts focused on communicable disease prevention by the ministry of health and social affairs. Annual medical inspection(health assessment) for school children for eyes, ears, nose, and throat were mandated nation-wide in 1951 by physical Assessment Act. 3. In 1979, the health instruction of schools to improve the health status of students was improved by health department in the Ministry of Education. 4. Experiences in healthful environment were basic components of the school health program. However, without careful planning and supervision these experiences were not contributed to the goal of school health. The formal program of school health environment were initiated in 1979. 5. In 1980, the guidelines of school health clinic management were prepared by Ministry of Education such as guidance of essential degrees and facilities in school health clinic. 6. Two patterns of administration of school health programs existed in Korea. In one the school health department operated its own health program and in the other the physical education department operated the health program within the school system. The school health department was established in Ministry of Education from 1979 to 1982. Improved school health programs will be a key element in the comprehensive national child health policy whic I will ask the Ministry of Education to develop for the Department.

Photosynthesis and respiration rate of microalgae are important factors during advanced wastewater treatment research using microalgae, There are several equipments and measurement methods for measuring photosynthesis and respiration, with different challenges that occur during pretreatment and stabilization of the analysis process. Therefore, in this study, for accurate Photosynthesis and Respiration (P&R) analyzer measurement, the analysis process was divided into pre-processing, DO stabilization, and analysis stages and each was optimized to enable accurate evaluation. For this purpose, the effect of DO saturation of the sample on P&R analysis, DO stabilization according to the degassing flow rate, and photoinhibition of the OD level on photosynthesis was investigated. Based on our study results, when DO was supersaturated, photosynthetic efficiency decreased due to photorespiration, making it inappropriate as a P&R sample. In addition, 0.5 L-N2/min level was the optimal nitrogen degassing flow rate for DO desaturation. The inhibition of photosynthetic efficiency by self-shading caused by the increase in OD was observed from OD 2.0, and it was found that P& R analysis is preferably performed on samples with OD less than 2.0. In addition, based on the above three optimization results, an optimized P&R Analyzer instruction for accurate P&R analysis was also presented.

The purpose of this study is aimed at giving proof that helps the elementary practical arts education system accomplish as the effects are turned out experimentally. Two classes of the sixth grade of J elementary school in Dae-gu have been selected in order to be experimented. One was chosen as an experimental group, the other was done as a comparative group. The creative-problem-solving learning-model was applied to the experimental group, and the traditional way of teaching was applied to the comparative group. For four classes of the sixth grades, ‘chapter 8: Making with recycled materials’ was proceeded as the content. Then. tests about the way of environmental awareness and creativity were carried out twice. After that, the results of pre and after-test in the comparative and experiment groups were compared using the t-test method. Following the analysis of the data collected in this study. the following major observations were obtained: First, children who were educated the creative problem-solving in a practical arts education achieved higher scores than before. Therefore, it turns out that the CPS method is an effective way to improve the environmental awareness in children. It showed that it included lots of daily habits connected with daily life and it made the intention to carry out the environment-preservation stronger and children´s attitude towards the environment improved. Moreover, making with recycled materials was used to solve an environmental problem, affecting in a positive way in our life. It also made the positive recognition about the environment. Second. the application of the creative problem-solving class of the practical arts education can make positive results to children. It helped children to have more interest in the environment around them. Children´s fluency, flexibility and originality in their ideas were improved as much as possible while they were solving problems. Consequently, the application of the creative problem-solving class model of elementary practical arts environmental education lets children expand environment consciousness and creativity.
