This paper proposes an intelligent method for the optimal load distribution of two cooperating robots(TCRs) using fuzzy logic. The proposed scheme requires the knowledge of the robots' dynamics, which in turn depend upon the characteristics of large flat panel displays(LFPDs) carried by the TCRs. However, the dynamic properties of the LFPD are not known exactly, so that the dynamics of the robots, and hence the required joint torque, must be calculated for nominal set of the LFPD characteristics. The force of the TCRs is an important factor in carrying the LFPD. It is divided into external force and internal force. In general , the effects of the internal force of the TCRs are not considered in performing the load distribution in terms of optimal time, but they are essential in optimal trajectory planning: if they are not taken into consideration, the optimal scheme is no longer fitting. To alleviate this deficiency, we present an algorithm for finding the internal-force factors for the TCRs in terms of optimal time. The effectiveness of the proposed system is demonstrated by computer simulations using two three-joint planner robot manipulators.

The purpose of this study is to explore high school students' environmental literacy and from its result, to suggest ways to reform environmental education. 1047 students from Seoul and Kyeongki province participated in the survey. The questionnaire consisted of four criteria of environmental literacy including knowledge, skill, attitude and behavior. The result was analyzed and the factors which affect high school students environmental literacy were explored. From this result, we made suggestions to improve environmental education as follows. First, environmental education in school should focus on knowledge criterion. Though school environmental education has been helpful for students to build environmental literacy in attitude and behavior criteria, its effect has not been good enough in knowledge criterion. Second, science education can enhance students' environmental literacy. Students who like science best and students who belong to science major classes were reported to possess better understanding in knowledge criterion. Also, students who like life science appeared to have a more positive attitude in environmental literacy. Third, informal education must be considered to form students' environmental literacy. In particular, the effect of mass media is inarguable. Thus, we should find a way to link formal education and informal education to improve environmental education. Fourth, high school students' interest in the environment must be encouraged since it is evident that higher interest would result in better outcome in environmental education.

This study was to examine elementary students' expectations on informal science learning in science museums which have characteristics of free choice learning. $5^{th}$ and $6^{th}$ grade students in two different elementary schools in Gyeonggi province participated in the survey and 330 samples were collected. Subcategories for the survey were categorized on the basis of review of the literature about the learning outcomes from science museums. The survey instruments were developed following the idea of each subcategory from the learning in science museums and a content validity of the survey instruments was checked. The results were as follows: Generally students' had high expectations of all subcategories and developing their interests in science through science museums was confirmed the most. Moreover, expectations on learning in science museums were differences between gender and grade. Finally, it was found that grade differences of expectations on learning in science museums were affected by intrinsic motivation, and empirical activity were affecting the gender differences of those. Based on the results of study, elementary students could confirm that the science museums had the important values and possibility as a field of informal science learning. And this study implied that the science museums could enhance more educational roles of informal science learning.

This study was focused on analyzing students' informal reasoning patterns and their considerations in decision-making on socioscientific issues. This study involved 20 undergraduate students (10 biology majors and 10 non-biology majors) and showed how the two groups responded on socioscientific issues. Semi-structured interviews were conducted twice respectively based on six scenarios of gene therapy and human cloning. The result showed 93% of the total number of participants' decisions were made by rationalistic reasoning, whereas emotional reasoning was 49%, and intuitive reasoning was 27%. Students usually used two or three informal reasoning patterns together. Most of the students took more consideration on social factors. Some perceived ethical and moral implications of the issues, but they did not consider them seriously. They made their decisions depending on their own values, etc. 65% of the participants got their information on socioscientific issues from the mass media. Biology majors hardly used intuitive reasoning compared to non-biology majors. The Biology major group took into deep considerations on socioscientific issues while the non-biology major group seemed to interpret the given scenarios simply. This implied that the content knowledge was a significant factor of their decision-making. Therefore, it is necessary to develop proper science courses for non-major students to improve their decision-making on socioscientific issues. So, when we develop educational materials or programs, we should consider students' reasoning patterns, their considerations in decision-making, and their content knowledge. And because the mass media has the potential to play a key role for an effective education, we need to make a plan to make a practical application.

We assumed that natural history museums have rooms for functioning as institutions for the environmental education, especially in aspects of multi-disciplinary, informal education. So we set goals of this research as finding 1) how much environmental education contents are reflected in exhibits of natural history museums, and 2) what those characteristics in aspects of dimension, range, and topic are. First, we developed a framework for analyzing of environmental education contents. Second, we applied the framework to seven major natural history museums. As the result, environmental education contents are reflected by 69.1% totally. Especially, the 'knowledge' dimension covered mostly, and among them the range of 'elements of Ecosystem' occupied more than other ranges. With inferring our results, we suggested that characteristics of natural history museums in environmental education are followed; spatial-temporal expansion of bio-diversity concept, visualizing impacts of human activity against nature.

Science festivals have occupied a very important axle in informal science education that enables students to experience the amazement of scientific experiments to think over scientific principals beyond the formal education in the classrooms. Among the concerned person, the most benefit-taken group may be the assistant who help the participants experience the activities in the festival. In order to find out the ways to make the student assistant's participation into a meaningful education experience, we analyzed the types of the activities in the science festival as well as the characteristics of the interaction between the student-assistants and the participating students are studied. The research findings are as follows: First, most activities in the science festival had related to the scientific concepts or principals; however, the understanding of the concepts and principals didn't highly affect the procedure of the activities. In many cases the students operated and made results without checking the related concepts or principals. Second, the student-assistants showed the consistency of operation in guiding their activities. They were explaining mainly the process of the experiments without giving a chance to think of related concepts or principles. We suggest that teacher should consider the student-assistants' learning in the festival as well as that of the participants.

자연수의 나눗셈에 관해 초등학생이 가진 비형식적 지식을 조사하고 그 결과를 학교에서 지도하는 형식적 지식과 연계하여 의미 있는 시사점을 찾고자 하였다. 이러한 목적을 달성하기 위해 자연수의 나눗셈과 관련하여 형식적 지식을 배우지 않은 학생이 가진 비형식적 지식은 무엇이고, 문제를 해결하는 과정에서 형식적 지식을 학습한 학생과 형식적 지식을 학습하지 쟈은 학생의 사고 전략의 차이를 분석하였다. 이를 위해 1, 2, 3학년 학생을 대상으로 질적 연구를 하여 다음과 같은 결론을 얻었다. 첫째, 자연수의 나눗셈에 관한 초등학생의 비형식적 지식은 구체물에 의한 전략에서부터 사칙연산에 이르기까지 다양하다. 둘째, 형식적 지식을 학습한 학생은 형식적 지식에 문제 해결방법이 한정되어 있어 다양한 전략을 사용하지 못한다. 셋째, 나눗셈 지도가 전혀 이루어지지 않은 1, 2학년 학생이 스스로 비형식적 지식을 사용하여 문제를 해결할 수 있다는 것은 알고리즘의 습득이 문제 해결의 전제조건이 아니라는 것을 보여 준다. 넷째, 수학적 지식을 가르칠 때. 비형식적 지식과 연계하여 형식적 지식을 가르칠 필요가 있다. 다섯째, 수학과의 연산 영역에서도 알고리즘에 치중한 지도가 아닌, 다양한 전략의 지도가 필요하다.
