This paper presents a system which recognizes dynamic hand gesture for virtual reality (VR). A dynamic hand gesture is a method of communication for human and computer who uses gestures, especially both hands and fingers. Since the human hands and fingers are not the same in physical dimension, the produced by two persons with their hands may not have the same numerical values where obtained through electronic sensors. To recognize meaningful gesture from continuous gestures which have no token of beginning and end, this system segments current motion states using the state automata. In this paper, we apply a fuzzy min-max neural network and feature analysis method using fuzzy logic for on-line pattern recognition.

The general fearfulness of hospitalized school-age children and the emotional anxiety of their mothers were investigated and compared to those of normal children and their mothers, in order to provide theoretical basis for establishing comprehensive nursing care of hospitalized children including their mothers. The present study was carried out from Sept. 5th to Oct. 3rd, 1983. A total of 81 hospital I zed children and their mothers were investigated and 95 normal elementary school children and their mothers as control group were surveyed The general fearfulness of children and the emotional anniety of their mothers were measured through questionaire by using Geer's FSS-Ⅱscale and Spielberger's STAI scale, respectively. The results were analyzed by computer using S.P.S.S. program and summarized as follows: 1. The emotional anxiety of the mothers of hospitalized children was greater than that of normal children's mothers. (P=0.000). 2. The general fearfulness of hospitalized children was greater than that of normal children (p=0.000) 3. The general fearfulness of hospitalized children varied with children's age and sex, mother's age and mother's experience of hospitalization. a) The general fearfulness of the hospitalized children at the age of 7∼9 was greater than that of the age 10∼12. (P=0.020) b) Girl's scored greater fearfulness than boys. (p=0.037) c) The younger mother's age resulted in the higher children fearfulness. (P= 0.0059). d) When the mothers did not have experience of hospitalization, the children's fearfulness was high. (P=0.014) 4. The anxiety-state of hospitalized children's mother was proportionally reacted to their anxiety-trait. (r=0.694, p=0.000) 5. The relationship between mother's emotional anxiety and their hospitalized children's general fearfulness failed to show statistical significance. (r= 0.1184, P＞0.05). These results indicated that the general fearfulness of hospitalized children was affected by environmental factors beside mother's emotional anxiety. An extensive study on the factors influencing the general fearfulness of hospitalized children is needed.

21C future learners are required to have creative thinking and problem-solving capability to address an issue wisely by integrating and applying knowledge and functions. The robot education that has recently been studied in primary and secondary schools was reported to be effective in satisfying the requirements. The robot education varies ranging from the existing after-school education to an integrated approach used for regular curriculums, and has actively been studied. Nevertheless, aside from positive study results, any studies on the environment where primary school students can learn robot and programming knowledge more friendly is still insufficient. Therefore, this study was intended to give students a robot class with the use of storytelling friendly to students in order for primary school students to learn robot and programming knowledge with ease. The study result showed that acquirement of programming knowledge was improved, and that the students had a positive learning attitude. In addition, it was found that the storytelling of the robot class helped provide the entire learning context and continuous learning motivation for the students.

Modern internet service is characterized as opening, sharing and participation based on Web2.0 so that users might actively participate in the internet environment. In this study, we suggested an instructional model based on precedent model of robot programming to promote positive interaction in Web2.0 environment. First, we figured out implications of precedent research through review the environmental features of Web2.0 and educational tools, robot programming learning model. Also, we suggest an instructional model using Web2.0 tools(cyworld, prezi, Mindmeister) for promoting interaction and applied it to learners. As a result, we have acquired positive results of robot programming education using Web2.0 tools. Most participants were evaluated that Web2.0 tool would be helpful to the overall robot programming course.

Software education will be implemented in elementary, middle and high schools from the 2018 school year. One of the core contents of software education is algorithm education. As with other subjects, algorithmic education can also be seen as the success of students' initiative. And students' initiative learning can lead to increasing students' interest and commitment. In this paper, I propose the concept of software battle by applying sports games to algorithm education. The software battle defined that the programmed objects play to solve a given problem without human intervention in the virtual world. This can be applied to various topics. In this paper, I tried to apply it to sorting numbers which is a representative subject of algorithm education. The results of applying the algorithm education to the software battles showed a positive response, although the students felt the unfamiliar side. This indicates that the software battle can be used as one of the various education methods.

As a way to improve the software education ability of the pre - service teachers, we conducted programming learning using two types of programming tools (Python and Scratch) at the regular course time. In programming learning, various types of errors, which are factors that continuously hinder interest, achievement and creativity, were collected and analyzed by type. By using the analyzed data, it is possible to improve the ability of pre-service teachers to cope with the errors that can occur in the software education to be taught in the elementary school, and to improve the learning effect. In this study, logic error (37.63%) was the most frequent type that caused the most errors in programming in both conventional language that input text and language that assembles block. In addition, the detailed errors that show a lot of differences in the two languages are the errors of Python (14.3%) and scratch (3.5%) due to insufficient use of grammar and other errors.

In the digital age, children can express their ideas in both physical and digital environments. Electronic textile or e-textiles with Lilypad Arduino provides children with opportunities to explore design ideas and to realize their imagination into physical artefacts. This study aims to analyze the nature of activities and perceptions among 16 children in fifth and sixth grade in a primary school in Seoul who participated in the 12-week e-textile project. To this end, two teachers who taught the class evaluated student-created artefacts from technical, critical, creative and ethical perspectives, and interviewed seven students to extract concrete experiences. The contribution of this study is that it offers a case study of how e-textile programs integrating arts and technology can be implemented in primary school settings and provides implications for future research directions.

In recent years, we can see attempts to take advantage of UCC in a way of the education. But in the precedent studies there are not many guidance plans to help teachers apply UCC in the classroom. The purpose of this paper is to suggest a guidance plan to help teachers apply UCC in the classroom and to analyze the effect of educational using UCC Dramatization learning model on the expanding of students' self-directed learning ability in the information communication ethics education. For this, first, a teacher executes preliminary inspection about self-directed learning ability second, students study about "how to prevent them from cyber crime" using UCC Dramatization learning model. Third a teacher executes post inspection about self-directed learning ability and measures the degree of improvement on self-directed learning ability. The final step is to extract the implications from the analysis of the experiments.
