In this paper we describe the integrated development environment for embedded software education. Our environment uses a cheap and widely available portable game console, Nintendo DS-lite. We have integrated open source development tools, and have implemented download shell, remote debugger. The results are all open source, and were used for university class for real embedded software education.

The purpose of this paper is to define and study some new classes of sets by using nano operation namely, ζ-nano regular open, ζ-nano open, ζ-nano α-open, ζ-nano pre-open, ζ-nano semi-open, ζ-nano b-open and ζ-nano β-open in nano topology. Some properties and the relationships between these sets and the related concepts are investigated. Also, we found the deciding factors for the most common disease fever.

Open education is carried out and studied in both phases of theory and practice in Korean elementary schools in these days. 1 introduced three open teaching and learning methods which we can use practically in elementary school mathematics education. They are the teaching and learning by open-end-approach, From problems to problems and Problem posing. First, I illustrate each meaning of three teaching and learning methods. Next, I presented the concrete plans of each teaching and learning method, and exhibited some examples of students' own works.

The purpose of this study was to analyze stages of the concern on open inquiry of elementary school teachers. To achieve this purpose, this study used the instruments of CBAM, including stages of concern questionnarie. The results of this study was as follows. Firstly, most teachers were in 0 stage, which meant they had little concern on open inquiry in science instruction. Secondly, the teachers who had teaching career of less than or 10 years were no more interested in open inquiry than teachers who had teaching career of 11-20 years. Thirdly, the training experience and teaching experience of open inquiry didn't show a statistically significant difference. Based on these results, this study suggested that we need educational programs and supporting strategies to heighten concerns and enthusiasm of teachers and pre-service teachers on open inquiry in science instruction.

The purpose of this study is to search for the effective way of development in managing Open Education Schools by analyzing obstacle reasons for school management of elementary school teachers on the basis of classroom site. This study researched 240 teachers and head teachers in three cities and counties of Chungbuk province through questionnaires which enquire obstacle reasons for Open Education. This research regarded 9 items including curriculum management and teaching method as main factors for consisting of Open Education School. And this analyzed the reactions from the percentages of interviewees. As a result of this analysis. obstacle reasons are as follows. 1. priority for academic background and the lack of school facilities and materials. 2. deficiency of teachers' belief in Open Education and unskilled practice. 3. closed situation in decision making and communication. 4. unreasonable management of finance and school facilities.

This study extracts the plan that is suitable to open education through the assessment and analysis of the open education environment. For this, the questionnaire survey of teachers at the elementary school in Kyengsang-bukdo was used. The results of this study can be summarized as follows; 1) In the estimation of satisfaction on the classroom environment for open education, although the score of "Comfortableness" is high, the scores of "Variety", "Convenience", and "Silence" are low in satisfaction. 2) The image on the classroom environment is highly regarded in general in "Stability", "Nobleness" and "Activity". However, it is necessary to devise some methods to improve the image on "Stability", when removing the wall between classrooms and corridors. 3) To improve the satisfaction and image associated with classroom environment, it is important to maintain suitable size of school and density of classroom. 4) The factors of satisfaction and those of image are correlated each other. Thus, to enhance the total image on the open class, it is necessary to improve the whole classroom environment.

The aim of this study was to explore teachers' values about teaching mathematics in the classrooms which implemented Lesson Study and Open Approach as a teaching approach. The targeted group was 83 school teachers from 4 schools participating in a teacher professional development project. The data was gathered through teacher questionnaires, lesson observations and interviews. Data analysis is based on Bishop's (1988; 2003; 2007) and Komin's (1990) frameworks. The results from the implementation of Lesson Study and Open Approach in Thai classroom found the different of the roles and behaviors of teachers and students in classroom. The results revealed 3 kinds of values about teaching: Mathematical values, General educational values, Mathematics educational values and also found that most of the teachers valued problem solving as an innovative teaching approach as against traditional approaches they were familiar with.

Purpose: This study was conducted to evaluate the effect of open laboratory self-directed practice in improving nursing skill competency. Method: This study was a one group posttest only design that examined the competency in basic nursing skills after traditional education and open laboratory self-directed practice. Students participated in traditional education and open laboratory practice through self-study. Whenever practice was done, the item of practice and time were measured and documented. Collected data were analyzed by frequency, percentages, averages and standard deviations, and Pearson correlation coefficients. Result: 1 The average number of students who participated in the open lab self-directed practice was 53.9 (64.2%) and the total number of hours of participation was 1567.5 minutes per year. Each student participated for an average of 29.1 minutes per year. 2. Analysis showed a statistically positive correlation between practical skill and open laboratory self-study (r=0.252, p=0.048).

The notions of P-I-open (closed) mappings, P-I-continuous mappings, P-I-neighborhoods, P-I-irresolute mappings and I-irresolute mappings are introduced. Relations between P-I-open (closed) mappings and I-open (closed) mappings are given. Characterizations of P-I-open (closed) mappings are provided. Relations between a P-I-continuous mapping and an I-continuous mapping are discussed, and characterizations of a P-I-continuous mapping are considered. Conditions for a mapping to be an I-irresolute mapping (resp. P-I-irresolute mapping) are provided.
