  • In this paper, we propose a method of cooperative control based on immune system in distributed autonomous robotic system(DARS). Immune system is living body's self-protection and self-maintenance system. Thus these features can be applied to decision making of optimal swarm behavior in dynamically changing environment. For the purpose of applying immune system to DARS, a robot is regarded as a B lymphocyte(B cell), each environmental condition as an antigen, and a behavior strategy as an antibody respectively. The executing process of proposed method is as follows. When the environmental condition changes, a robot selects an appropriate behavior strategy. And its behavior strategy is simulated and suppressed by other robot using communication. Finally much simulated strategy is adopted as a swarm behavior strategy. This control scheme is based on clonal selection and idiotopic network hypothesis. And it is used for decision making of optimal swarm strategy.

  • The purpose of this study is to propose an architectural design process adopting design concepts with weight on them. The process of the study is as follow; First, design concepts for the study are classified by the hierarchy. Developing process of those design concepts which had been adopted for a creative thinking was investigated. Second, after putting different weight on diverse design concepts, this study propose a design process adopting design concepts with different weight. Finally, the proposed process adopting design concepts with weight was verified through a case study of elementary school project. The case study was carried out by questionnaires 3 times. Experimental results verified the hypothesis which was about the process adopting design concepts with different weight. Architects can precede their design process with confidence about setting design concepts by the result of this study.

  • In this paper, we propose a method of cooperative control(T-cell modeling) and selection of group behavior strategy(B-cell modeling) based on immune system in distributed autonomous robotic system(DARS). Immune system is living body's self-protection and self-maintenance system. Thus these features can be applied to decision making of optimal swarm behavior in dynamically changing environment. For the purpose of applying immune system to DARS, a robot is regarded as a B cell, each environmental condition as an antigen, a behavior strategy as an antibody and control parameter as a T-call respectively. The executing process of proposed method is as follows. When the environmental condition changes, a robot selects an appropriate behavior strategy. And its behavior strategy is stimulated and suppressed by other robot using communication. Finally much stimulated strategy is adopted as a swarm behavior strategy. This control scheme is based of clonal selection and idiotopic network hypothesis. And it is used for decision making of optimal swarm strategy. By T-cell modeling, adaptation ability of robot is enhanced in dynamic environments.

  • The importance of classes aiming at enhancing students ability in problem solving and decision making has been being recognized as chances of individual citizen for taking part in social decision making processes. This study was intended to find whether teachers' opinion presentation have effects on students' decision making in a class introducing environmental issues. Total of 6 classes, 202 middle school students have participated in a series of experiments including 4 different environmental issues. Only two issues had been addresses in classes as experimental issues and other two issues not addressed as control issues. For each of the two experimental issues, the teacher researcher applied three different approaches to his students that included positive, negative, or no opinion. The results of this study can be summarized as follows; First, the results showed that students changed their decisions on environmental issues more frequently when dealing with those issues in a class than when not dealing with them. Second, as examining the relationship between patterns in which students make decisions and whether a teacher proposed his opinions or not, it is shown that the rates of students whose opinions is not changed nearly have no difference, while when teachers propose their opinions, it is shown that students who haven't yet chosen their positions easily make their decisions into pros or cons, compared with the opposite case. Third, the results of this study partly supported the third hypothesis that teachers opinion presentation would effect on decision-making of students. It was found that there has been a significant effect in the case of car free day system issue, but no statistically meaningful result in the case of no pets in the national park issue. However, in the issue of car free day system, it seems pretty clear that the students followed the direction of teachers' opinion no matter what it was pros or cons.

  • 본 연구에서는 파급효과를 예측하는 것에 따라 의사결정의 어려움이 달라지는지, 그리고 파급효과 예측과 의사결정 어려움 사이의 관계를 의사결정 결과에 대한 책임감과 부담감이 매개하는지 살펴보았다. 연구 1에서는 정책 결정 상황을 제시하여 예측된 파급효과의 크기와 의사결정 어려움 간의 관계를 알아보았다. 그 결과, 결정의 파급효과를 크게 예측할수록 의사결정 시 어려움을 더 크게 경험한 것으로 나타났다. 연구 2에서는 예상되는 파급효과의 크기를 실험적으로 조작하여, 파급효과를 크게 예상하도록 한 조건과 작게 예상하도록 한 조건 사이에서 도덕적 의사결정을 내릴 때 경험하는 어려움의 정도가 다른지 알아보았다. 또한, 예측된 파급효과의 크기와 의사결정 어려움 사이의 관계를 의사결정 결과에 대한 책임감과 부담감이 매개하는지 검증하였다. 그 결과, 가설과 일관되게 예측된 파급효과의 크기가 작은 조건에 비하여 큰 조건에서 위해/돌봄, 공정/호혜, 그리고 내집단/충성심 관련 도덕적 의사결정 시 어려움을 더 크게 경험하는 것으로 나타났다. 이러한 관계를 의사결정 결과에 대한 책임감과 부담감이 매개하는지 살펴본 결과, 부담감의 매개효과가 내집단/충성심 관련 도덕적 의사결정에서 관찰되었다. 이러한 연구 결과를 토대로 본 연구의 의의와 제한점, 그리고 후속 연구 방향에 대하여 논하였다.

  • The goal of the environmental education in High School is to make students survey and work out the issues on environment and to help them continue and improve the work. It is important that we should educate students the rational ability of decision-making. The more they can make decisions rationally, the more they participate actively in that. The purpose of this study is to develope the model of a new teaching-learning method coinciding with the goal of the environmental education of Social studies in High School. This study is backed up by the following developing processes. To begin with, the contents related to environmental problems in Social Studies Curriculum are being investigated. To urge the importance of STS(Science, Technology and Society), 1 will present the righteous understanding of Science in societal contexts, the development of rational decision-making abilities, and the cognitive connections between society and science. For this, 1'm representing a new model of learning-teaching method, backed up by Constructivism, especially Vygotsky's ZPD theory, giving 4 steps from everyday concepts to natural lingistic thought. Based on the above hypothesis, at last I will represent a STS whose topic is a problem of beach preservation because I intend to show the possibility of STS on the environmental education of Social Studies through this study. This study will help us lay a foundation stone of introducing STS in environmental education of Social Studies.

  • This main purpose of this study was to assess the effects of two different types of ethics education on the moral judgement of clinical nurses. One type was free discussions among nurses with given specific moral issues and the other type was discussions guided by experts on specific moral issues. The study employed a quasi-experimental, nonequivalent pre test-post test design using two different control groups. The conceptual framework of the study was derived from the Kohlberg′s Moral Development Theory (1969) and the Greipp′s Ethical Decision-Making Model (1992). The data was collected during the period of October 14 through December 15, 1998. Sample consists of 32 nurses working in the ICU who met research criteria. 16 nurses were assigned to the free discussion group and 16 nurses to the group for the guided discussion with experts group. For the pre-test, the DIT which was developed by Rest (1984) and JAND by Ketefian (1998) were used with some modification by the author. After the education, only JAND was used to assess the changes in moral judgement. The collected data was analysed using SPSS PC program. The findings are as follows: 1. There was no significant difference between two groups in their general characteristics. Only difference which was statistically significant between two groups was that realistic score on Case 3/Medical Research and Autopsy was higher in the free discussion group. 2. Hypothesis 1: "There will be a difference on the moral judgement of nurses before and after they receive an ethics education". This hypothesis was supported partially. Those who had low scores on moral judgement before the education tended to have higher scores after the education on the same issues. And, after the education, the nurses tend to give lower scores on the dilemmas they had experienced frequently at work; while giving higher scores on those dilemmas they had no prior experience. 3. Hypothesis 2: "The effect of education may differ depended upon the moral development index [P(%)] score of nurses". The effect of education was different depend on moral development level. The group who′s P(%) scores was low at the pretest has higher scores in realistic moral judgement after the education, while the groups with middle or high P(%) scores went down after the education. These changes were statistically significant in some cases, thus, the Hypothesis 2 was partially supported 4. Hypothesis 3: "The method of ethics education will have different effects on the moral judgement of nurses". Even though several nurses attended the guided discussion stated that the education program broadend their perspectives the difference between two groups was not significant and this hypothesis was not supported. In conclusion, both types of ethics education had helped the nurses to acquire the skills to deal some nursing dilemmas. The effects of ethics education may differ according to the moral development index - P(%) score. However, because of some of the limitations of this study, mainly small sample size, short term education, unable to control other variables which may affect moral judgement of nurses, further research is warranted.er research is warranted.
