In the teacher's guide of mathematics textbook for the 1st grade of the middle school, the clear and logical reason why the multiplication of negative number to negative number makes positive number, and $a^{-m}$ with a>0 and m>0, is defined by ${\frac{1}{a^m}}$ is not given. When we define the multiplication or the power by successive addition or successive multiplication of the same number, respectively, we encounter this ambiguity, in the case that the number of successive operations is negative, In this paper, we name this number, negative counting number, and we make the following more logical and intuitive definition, which is "negatively many successive operations is defined by positively many successive inverse operations." According to this new definition, we define the multiplication by the successive addition or the successive subtraction of the same number, when the multiplier is positive or negative respectively, and the power by the successive multiplication or the power is positive or negative, respectively. In addition, using this new definition and following the E.R.S Instruction strategy which revised and complemented the Bruner's E.I.S Instruction strategy, we develope new teaching model available in the 1st grade class of middle school where the concept of integers, three operations of integers are introduced.ntroduced.

Background: Atopic dermatitis starts as an early childhood type I hypersensitivity to environmental allergens and is often the first step in the atopic march to develop into asthma and allergic rhinitis. Despite progress that has been achieved in management, this health problem remains poorly controlled and cause great pain and suffering for many children and their parents To introduce nurses to recent progress in pathophysiology, management and preventive measure of atopic disease. Search method: Systemic search was done using the PubMed and CINAHL from 1980 to 2005. In addition, historical references were taken from standard medical textbook. Results: In total, 30 relevant publications were located including primary research and review articles that cover the pathophysiology, management, and preventive measure of atopy. The evidence emerging from literature indicate that non-medical approaches such as breastfeeding and probiotics would improve management outcomes. Conclusion: The review suggests that breastfeeding and probiotic approaches would be the most effective preventive measures for children with atopic diseases.

This study analyzed the aims, contents, and methods of early education in Sohak(小學) a textbook for childhood education in the choson Dynasty. The analysis was based on the 6th Korean National Kindergarten Curriculum(in process) and the theories of education in Sohak. Sohak consists of Establishing the Education Process(入敎), Clarifying the Cardinal Human Relationships(明倫), Reverencing for the Self(敬身), Examining Antiquity(稽古), Admirable Sayings(嘉言), and Exemplary Deeds(善行). The aim of education in Sohak was to preserve Sheng(性), i.e. human nature inherited from heaven. The contents of education in Sohak was divided into 6 groups: distinction by age and sex, health, basic life habits, private life, family life, and group life. Methods of education in Sohak was the consolidation of knowledge and conduct, education of self control, learning of exploration, learning of constructive models, learning of keep the stages and telling stories of the sayings of the saints.

In this research, researcher will examined the theoretical background of open education. Based on the result of the development of the suggested guidelines for a home economics teaching/learning program, researcher concludes that in order for the teaching/learning programs based on open education to be efficiently acieved in the classroom environment-organization at the middle school the following reform measures must accompany these programs. First, in order for the special characteristics of open education, i.e., individualized and small group study, to be effectively achieved, it is necessary to improve the physical classroom environment-organization. Second, the two class hours per week currently allotted for home economics are not sufficient to convey the information in the textbook. In order to reach objectives of teaching home economics according to open education a guarantee of a few more class hours is demanded. Third, in order to successfully achieve teaching/learning programs following open education, it is necessary for home economics teachers to make efforts to develop educational materials, and to engage in ongoing research and inservice training. For this to occur, measures must be taken to reduce the workload of teachers.

Since the educational guideline on Information and Communication Technology(ICT) was announced, almost every school has taught about ICT during the discretionary classes. Although research on the computer curriculum and comparative studies on computer textbooks have been conducted, a study on the current status of the use of computer textbooks has not been carried out yet. On the basis of such needs, this study was conducted to investigate the current status of the use of computer textbooks in elementary schools(i.e. how teachers use computer textbooks in schools, and what teachers and students think about computer textbooks), and to suggest ideas to be considered in order to improve the quality of computer textbooks. The main finding of this study is that although most teachers use computer textbooks, the frequency of use is low and teachers use the textbook by revising or complementing its content. Also, most teachers respond negatively to some aspects of computer textbooks(i.e. level-based learning, reconstructional facility, systemicity, enhancement of exploring and creative ability, induction of interest, enhancement of self-directed learning, and assignments). In contrast with this result, students respond negatively only to the vocabularies used in computer textbooks. In addition, teachers showed significantly different responses according to their age and teaching experiences, and students demonstrated significantly different responses according to their gender and the frequency of the use of computer textbooks.

A variety of educational policies have been implemented to educate outstanding individuals who will lead the future and to adopt supporting systems. For the successful implementation of educational policies, it is crucial to identify the perception of teachers as main agents of education. This study conducted a survey with elementary teachers in Chungcheongbuk-do. The purpose of this study was to investigate teachers' perception on the major policies related to ICT(i.e., STEAM, Smart Education, Software Education, e-textbook, and EdudataSystem). This study also compared the distribution of teachers' perception on the policies. The results of the study indicated that teachers had relatively positive perception on the importance and the necessity of the policies. On the other hand, it was found that the levels of teachers' training experiences and readiness for teaching related to ICT were relatively low. In addition, the patterns of teachers' perception on STEAM, Smart Education and Software Education were similar. Based on the results, the study suggested that appropriate support and educational strategies for effective implementation of policies should be established.

$Ch\acute{e}n\;Xiuyu\acute{a}n$(陳修園) was a famous doctor and educator of the late Tang Dynasty. He was well known both for his books for beginners, and for his unique medical theories based on his profound research of <$Sh\bar{a}ngh\acute{a}nl\grave{u}n$(傷寒論)> and <$J\bar{i}nku\grave{i}y\grave{a}ol\ddot{u}e$>. He wrote <$Y\bar{i}xues\bar{a}nz\grave{i}j\bar{i}ng$(醫學三字經)> to establish the basic textbook for the beginners to set up right principles in pursuing their medical career. <$Y\bar{i}xues\bar{a}nz\grave{i}j\bar{i}ng$> was written in rhyme form, so that it can be easily memorized and used in future practices. There are quite many medical books in rhyme form, but this book is very unique as $Ch\acute{e}n\;Xiuyu\acute{a}n$ annotated his own notes, which is rare in this form of books. This feature makes <$Y\bar{i}xues\bar{a}nz\grave{i}j\bar{i}ng$> very outstanding, also with the fact that $Ch\acute{e}n\;Xiuyu\acute{a}n$ was the one with profound understanding and original theories based on medical bibles such as <$N\grave{e}ij\bar{i}ng$(內經)> and <$Sh\bar{a}ngh\acute{a}nl\grave{u}n$(傷寒論)>. We have translated this precious educational material into korean, hoping that this work could be of any help to students of korean medicine. And while doing this work, we have found followings: <$Y\bar{i}xues\bar{a}nz\grave{i}j\bar{i}ng$> covers the entire fields of medicine from theoretical discussions to practical clinical information. Nevertheless, as this is written in rhyme form, there are few phrases that are not easily understood for the sake of rhyme. Beginners probably may have difficulties in reading this book. To make this difficulty alleviated, and to develop our own educational material, we need to study further on the notes that $Ch\acute{e}n\;Xiuyu\acute{a}n$ annotated himself.
