The purpose of this study was to understand the teaching effects after conducting ASI module in the open inquiry activities of the elementary science class. in order to understand the effects of ASI(Authentic Scientific Inquiry) module application using science research notes in open inquiry activities to students` science research ability, The results of this study were as follow. First, the after test results were covariance-analyzed to be the effects to science process skills were statistically significant in 0.5 significance level. Second, in the covariance analysis of the after test of the study group and the comparative group, the effects to scientific creative problem solving skills were statistically significant in 0.5 significance level. Third, the covariance analysis of the after test in the effects of ASI module application using science notebooks to students` scientific attitude revealed that the two groups` average difference was statistically significant in 0.5 significance level. In conclusion, application of the ASI module using science notebooks had a positive effect on improvements of students` science process skills, science creative problem solving ability and scientific attitude. Therefore, the ASI module using science notebooks is hopefully to be provided as an effective instructive strategy in the open inquiry activities courses in school in the future.

본 논문에서는 정지궤도 위성 통신 안테나의 지향 및 장착위치를 정확하게 하기 위한 정밀정렬 방법과 그 측정 결과를 다룰 예정이다. 안테나의 지향 및 장착위치 관점에서 최적의 성능을 획득하기 위해 무중력상태가 모사되었으며 레이저추적 시스템과 데오드라이트 시스템이 적용되었다. 그 결과 정렬 안정성이 허용오차 ± 0.25㎜ 및 ± 0.013 ° 이내에서 검증되었으며, Ka 대역 전개형 안테나의 최종 정렬은 허용오차 ± 0.5㎜ 및 ± 0.015 ° 이내인 요구조건을 만족할 수 있었다. This paper will discuss the alignment techniques and measurement results of geostationary satellite communication antennas for correct antenna pointing and also the fixtures. To get the best performance in terms of antenna pointing and fixtures, zero G condition have been simulated and laser tracker and theodolite system have been applied. As a result, alignment stability was verified within the tolerance, ± 0.25㎜ and ± 0.013 °and finally Ka-band deployable antenna alignment has been accomplished within the tolerance, ± 0.5㎜ and ± 0.015 °.

The consciousness of environmental education has increased for the last decades, and schools make efforts for education in the systematic environment. To keep pace with trends such as the open school and the open class, students, teachers and parents are actively participating in environmental education programs. Parents` active participate in environmental education programs will provide excellent basis to operate environmental education efficiently and advise fruitful operation of environmental education programs. In addition, as parents play an important role of deciding the students` life habits or attitudes about environment, their participation is greatly meaningful. This study was conducted to 203 fourth and fifth graders in M elementary school in Ulsan city that operated the model school for protecting the forest from March to December, 2009 and their parents in order to examine the effects of parents` participation in environmental education programs, and the results are as follows. First, the student group with parents who participated in environmental education programs showed higher interest in surrounding environment of the school. Second, the student group with parents who participated in environmental education programs showed higher environment sensitiveness and environmental practice intention. Third, the parent group who participated in environmental education programs showed higher environmental sensitiveness and environmental practice intention. Fourth, the parent group who participated in environmental education programs showed higher satisfaction about the program. As the result of the study, environmental education programs with parents` participation attracted their active interest and participation about school environment problems, and a lot of conversation and attention between students and parents who participated in environmental education programs improved the students and their parents` environmental sensitiveness and environmental practice intention.

Recently, Korea`s interest in environment protection is increasingly growing, and Korea realizes the seriousness of environmental pollution and national movement to minimize the effect is arising. As part of the movement, the need of environmental education in elementary schools is on the rise. This study aims to develop integrated environmental experience programs allowing students to have experience activities in forests, rivers, and seas that they can approach easily around them and to have environmental education through various plays. In addition, the study purposes to compare general educational education programs in actual education in terms of the effect of the program on students` environment attitudes. This study was conducted to 50 fourth graders in two classes of S elementary school in Busan, and the 25-student comparative group had the normal educational education program that is mostly being performed in actual education while the 25-student treatment group had the survey on environmental attitude after a class using an integrated environmental experience program. The survey content is about environmental attitudes, and it consists of six subjects such as general environment, environmental pollution, energy, water resources, recycling, and animal protection and has 7 or 8 items by each subject which is divided into eight sub-items including sensibility, belief, values, spontaneity, criticism, patience, attention and interest. The findings are as follows. First, the integrated environmental experience program has a more positive effect on environmental attitudes than the general educational program. In particular, it is really effective about the topic of animal protection among students` environmental attitudes. Second, the integrated environmental experience program has a more positive effect on values and interests than the general environmental education program.
