Programming education can improve problem-solving skills and logical thinking required in a knowledge-based society. However, most conventional programming education spent more time to acquisition of command language and coding process rather than improvement of problem-solving skills and logical thinking, for using programming languages based on foreign language and learners have appeared to lost interest easily. To solve these problems in this paper, interest in programming study was enhanced by making it possible to verify the outcome of highly abstract programming process through a robot as a concrete object. In addition, the Hangul converter of robot programming language based on RCX that elementary school students can use easily was designed and developed. Furthermore, the developed tool was used for six months by students in after-school computer class and therefore learners showed a positive response.

To facilitate interaction between home robot and humans, it's urgently needed to make in-depth research in Human-Robot Interaction(HRI). The purpose of this study was to examine how children interacted with a newly developed home robot named 'iRobi' in a bid to identify how the home robot affected their psychology and the effectiveness of learning through the home robot. Concerning the psychological effects of the home robot, the children became familiar with the robot, and found it possible to interact with it, and their initial anxiety was removed. As to its learning effect, the group that studied by using the home robot outperformed the others utilizing the other types of learning media (books, WBI)in attention, learning interest and academic achievement. Accordingly, home robot could serve as one of successful vehicles to expedite the psychological and educational interaction of children.

Using the tangible programming tools, which combines physical objects (e.g. robot) and educational programming language, may help to encourage learners' creative thinking as well as to enhance problem solving ability. That is, learners can have opportunities to simulate problem solving processes through the physical objects, such as robots. Therefore, they can minimize an fixation about problem solving process. These experience is effective to induce creative thinking that is useful to find new solutions and change environment actively. Therefore, we developed a robot based programming teaching and learning curriculum and implemented it in college level introductory programming courses. The result shows that the robot based programming learning has a positive effect in all three factors of learners' creative problem solving potential, especially in a cognitive factor. The cognitive factor includes general problem solving abilities as well as factors that explain creativity, such as divergent thinking, problem recognition, problem representation. These result means that the developed robot based programming teaching and learning curriculum give positive effect to creative problem solving abilities.

The high performance intelligent robots have become to use a lot of sensors, actuators and controllers which are connected via bus-type networks while the point to point connection was widely used in-robot networks of existing robots. The bus topology makes the robot system share data internally and it can also reduce the weight of the robot because of smaller wiring harness. The CAN is one of serial bus communication protocols typically used for in-vehicle networks and now it can also be used for in-robot networks because of its low cost and reliability. A performance evaluation system for this type of networked system is developed to analyze the real-time operation and the reliability of a serial-bus network, and the usefulness of the developed evaluation system is shown by some experiments for a network of many CAN nodes.

전통적인 인공지능 계획방식은 완전한 월드 상태모델과 시스템 동작모델에 기초하여 처음부터 자동으로 작업계획을 생성하려는 접근방식이다. 그러나 지능로봇제어와 같이 불확실성과 가변성이 높은 실 세계 응용분야에서 이와 같은 전통적인 인공지능 계획방식은 효과를 얻기 어렵다. 반면에 많은 실 세계 응용분야에서는 그 분야에서 이미 잘 알려져 있는 작업 영역지식이나 제어지식들이 존재하며, 이들을 효과적으로 이용하는 것이 매우 중요하다. 이러한 방법 중의 하나로서 복잡도가 높은 작업계획을 전문가가 직접 편집해서 입력하는 방식이 널리 쓰인다. 기본 동작모델과는 달리, 일반적으로 작업계획 표현언어는 복잡한 제어구조를 포함하는 하나의 작업 프로세스로 계획을 표현한다. 따라서 이러한 복잡한 절차적 지식인 작업계획을 편집하고 검증하기 위해서는 편리한 모델링 도구의 개발이 필요하다. 본 연구에서는 PRS 계열의 작업계획을 비주얼 환경에서 편집할 수 있고, 가상 시뮬레이션 기능과 작업 계획기와의 연동 기능을 갖춘 PKM시스템의 설계와 구현에 대해 설명한다.

This study aimed to explore the relationship between Intelligent Robot Reacher(IRT)-student by examining the factors of their relationship perceived by middle school students. In doing so, we developed questionnaires based on the existing teacher-student relationship scale and conducted an online survey of 283 first graders in middle school. The collected date were analyzed using exploratory factor analyses with SPSS 23 and confirmatory factor analysis with Amos 21. The study findings identified four factors of IRT-student relationship namely "trust", "competence", "emotional exchange", and "tolerance". It is expected that the study can be used to discuss ways to enhance educationally significant interaction between students-IRT and teaching methods using intelligent robots(IRs). Also, the study will contribute to the understanding and development of various services using IRs. Based on the study finidngs, future studies should investigate the perception of various education stockholders (teachers, parets, etc) on IRT to elevate the Human-Robot Interaction in the education field.

A lot of studies in and outside the country says that robots can become an effective tool in developing creativity, problem solving skills and positive learning motivation in the knowledge and information era. This study aims to verify the educational effect of robots in mathematics education by applying robots to mathematics education as a learning tool in an effort to improve the teaching/learning environment. For this study, the mathematics curriculum of elementary school and robot programming were analyzed and then a robot integrated mathematics program was developed. The developed program was applied to the mathematics education of an elementary school year 5 over 16 times. The result of the study showed that the experimental group which used the robot integrated program has better learning attitude and problem solving skills than the group which used the traditional method. The result also showed that the mathematics activities that used robot programming contributed to developing problem solving skills and provided positive mathematics learning experience.

GRAFCET is the program language for a sequential control and utilized in the description of sequence of a process. This study is to implement GRAFCET editor and compiler for personnel computer. The GRAFCET editor module is developed to use as menu-driven method based on the graphic screen and the graphic symbol. So, users can use it interactively. The GRAFCET compiler module analyzes the already drawed GRAFCET diagram, then translates it to Z80 assembly code. After generating Z80 machine code from assembly code, we can send the outputed machine code file to Z80 one-board computer through RS232C. We have developed the GRAFCET programming tool to utilize under IBM PC/AT with the VGA monitor, and it may be contribute to low cost automation system.

This paper is focused on the development of a Toolbox to support the design of the PID control]or and to check tile performance of tile controller designed. Although it is common to use the PID controller in the industrial field, any toolbox for the PID controller has not been provided yet, which is the main motivation to research in this paper. At first, the methods of PID autotuning are reviewed, and then contents, structures and how to use of the toolbox developed are explained. In addition, some application simulations of this toolbox are performed to exemplify the performance of the toolbox developed iii this paper.

In this paper, the effect of neurofeedback training program on attention ability of ADHD children is studied. The main concept of a neurofeedback training program is a robot control with brain wave. To do this, Mindset(neurosky, ltd) was used as a brain wave measurement and lego NXT was used to a robot kit. The developed brain wave training program has a 12 chapter. Students meet a problem situation and they invent and make a problem solving robot with NXT kits. After that, they control the their own robot by their brain wave. Developed program was applied to 8 student who live in chunan area. To monitor a change of attention ability, attention behavior checklist, K-CBCL, CTRS-R, ADS were used. These checklist were recorded with before and after the program. The result shows that student attention ability is increase after the program in the most of the checklist.
