New mathematics textbooks for elementary school students are under development according to the 2015 national revised curriculum. Not only contents but also framework of textbooks may be interesting to the mathematics educators and researchers. Considering the high dependency on textbooks in elementary classrooms, the influence of the framework of textbooks in mathematics learning cannot be overlooked. The unit and lesson frameworks of the textbook are important because they are directly related to the quality of mathematic lessons, especially when teachers make a lesson plan based on the unit and lesson frameworks of the textbook. This study is to analyse the unit and lesson frameworks of elementary school mathematics textbooks and to find out elementary school teachers' preference about its analysed key points. For longitudinal analysis, we selected 3rd-grade mathematics textbooks of 5th, 6th, 7th, the 2007, and the 2009 national revised curriculums. For horizontal analysis, we selected 3rd-grade mathematics textbooks of Korea, Japan, United States and Finland. We compared unit and lesson frameworks of various textbooks, and abstracted key elements of the textbook frameworks, and constructed survey questions. Looking at results from survey questions based on analysed key points, we were able to grasp the teachers' preference for unit and lesson frameworks for mathematics textbook. Based on the results of this study, some implications for the development of framework for new mathematics textbooks are suggested.

This study was intended to survey and analyze the illustrations of the elementary science textbooks in the』 7th revised education curriculum in Korea, and to compare the results with the illustration organization of the elementary science textbooks of Japan. The analysis criterion was composed of two categories, the kind of illustration and the role of illustration. The kind of illustration was divided into five subcategories such as photograph, picture, illustration, cartoon and diagram. The role of illustration was divided into four subcategories such as motive induction, guidance for learning, the supply of material, the presentation of results. According to the analyzing criterion, the frequencies of relevant subcategories of illustrations in science textbooks were checked and arranged and the resultant data were analyzed by grades. The findings of this study were as follows: 1. Korean science textbooks have about 3.29 illustrations per page whereas Japanese ones have 4.1l. Compared with Korean science textbooks, Japanese ones have more illustrations. 2. From the analysis of the kinds of the illustrations by grade basis, it was found that the order of percentage of illustrations is photograph, cartoon and picture in both countrys' science textbooks. Korean ones are highly dependent on photograph. As a contrast Japanese ones have more ratio of cartoon and picture than Korean science textbooks. 3. The analysis of the roles of the illustrations by grade basis showed that the role of guidance for learning is major in both countrys' science textbooks. The role of guidance for learning is prominent in Japanese ones, but in Korean ones, the role of guidance for learning is a little higher than that of the supply of material.

The purpose of this study is to find research areas that were less represented by the researchers of mathematics textbooks and to provide feedback for the research and development of mathematics curriculum and textbooks. In order to complete this study, we analyzed comparative studies of mathematics textbooks published in Korean. This study analyzed 107 comparative studies published until recently based on following aspects: countries studied (North Korea, U.S.A., and Japan), Math curriculum studied (6th and 7th mathematics curriculum), and Math contents studied (probability and statistics) and etc. The result of this study suggests that the content area of creative problem solving was particularly less represented by the studies published and require more concern from the mathematics education researchers

This study investigated the models of four countries' elementary mathematics textbooks in Ratio and Rate and identified how multiplicative perspectives on proportional relationships and the structure of proportion situations are reflected in the textbooks. For this, textbooks of 5th and 6th grade textbooks in Korea Japan, Singapore and U.S. are compared and analyzed. As a result, we can find multiplicative perspectives on proportional relationships and the structure of proportion situations on pictorial models, ratio tables, double number lines and double tape diagrams. Also, the development of Japanese textbooks from multiple batches perspectives to variable parts perspectives and the examples of the use with two models together implied the connection and union of two multiplicative perspectives. Based on these results, careful verification and discussion for the next textbook is needed to develop students' proportional reasoning and teach some effective reasoning strategies. And this study will provide the implication for what kinds of and how visual models are presented in the next textbook.

The purpose of this study is to compare the eighth-grade mathematics textbooks of Korea, Japan on the one hand, and those of the United States and England on the other, and to explore the implications for mathematics education in the East and the West. As a result, the dichotomy between the East and the West were set up with the sacrifice of the details. First, the textbook development and publication policies of the East are characterized as uniformity, and those of the West are diversity. Second, for the choice of content, the East and West can be represented by essential and discretionary respectively. Third, the physical appearance of Eastern textbooks is rather plain while that of the Western textbooks is colorful, Fourth, in terms of the characteristics of the content, the dichotomies between the East and the West are linear vs. spiral, content vs. context, formal abidance vs. metacognitive shift, and simple vs. realistic. Each of the Eastern and Western approaches has its own weak points as well as its strong points. For instance, textbooks In the West may help students realize how useful mathematics can be in their lives, but if the link between a mathematical concept and the corresponding real life situation is not made clear, sometimes students may not be able to completely grasp the mathematical concept. In turn, the Eastern textbooks may succeed In conveying ideas in an economical way, but they often fail to motivate students to follow the course. Therefore it is important to take a critical view of each approach. It is through a critical understanding of the differences between different cultures that we are able to learn from each other and to put the results of such comparative studies to better use in the future.

In this study, we investigated how multiplication by 2-digit numbers had been taught in elementary mathematics textbooks of Korea, Japan, Singapore, and USA. As a result of analysis, we found as follows. Korean textbooks do not teach the multiplication by 10 and the multiplication by power of 10, but Japanese, Singapore, and US textbooks explicitly teach related content. In the '×tens' teaching, Japanese and American textbooks teach formally the law of association of multiplication applied in the process of calculating the partial product of multiplication. The standard multiplication algorithm generally followed a standard method of recording partial product result according to the law of distribution, but the differences were confirmed in the multiplication model, the teaching method of the law of distribution, and the notation of the last digit '0'. Based upon these results, we suggested some proposals for improving the multiplication teaching.

Objectives This is the review on the Jeolgyeong which means diagnosis method of meridian and acupoints. Detecting method of meridian and acupoints under the disease condition using fingertips were more developed in Japan than in China and Korea. This study is the introduction to the Japanese style palpation method on meridian and acupoints. Methods Firstly the textbook 'Acupuncture medicine' published by the committee of Korean professors' association of acupuncture and moxibustion was analyzed. Especially the contents of the palpation method on meridian and acupoints were focused and summarized and secondly the book describing the palpation method on meridian and acupoints was selected, translated and summarized. Results Until now the knowledge on the acupoints reaction depending on the patient's status, the deficiency pattern and the excessive pattern was rarely described in China and Korea. On the contrary, 4 kinds of reactions in the deficiency pattern and 4 kinds of reactions in the excessive pattern were well described in Japanese literatures. Mild touching, mild pinching, rubbing, mild pressing and severe pressing were also described along the meridians. Except the bladder meridian Back Shu points, Yuan points, Luo points, Xi(cleft) points, Front Mu points were depicted as the same as those in China and Korea. For the bladder meridian lines, 4 lines were organized including 2 lines of Hua-Tuo-Jia-Ji-Xue and the middle line between 1st and 2nd bladder meridian line as well as 1st bladder meridian line and 2nd bladder meridian line. Conclusions Detecting meridians or acupoints and using them for diagnosis and treatment is a method used in China, Korea, and Japan. However, detailed descriptions of the method for detecting meridians through palpation are revealed in Japanese books. Palpation methods for diagnosing meridians using touching, pinching, rubbing, and pressing methods are expected to be standardized and systematically learned in Korea.

As the rate of foreign workers increasing, the rates of their children are rising, as well. The children's native countries vary from Japan, China to Indonesia, and difficulty of learning is expected in their entering the regular education due to the differences in the contents and curriculum they had learnt. This study analyzed the science textbooks of five Asian elementary schools including Korea, China, Indonesia, Thailand, and Iran-in diversified sides focusing on the content of earth science, for the children of foreign workers. The characteristics of the elementary science textbooks of the subject countries were compared in seven criteria-the rate of earth science in the textbooks, how units are arranged, whether the earth science contents are included, the contents highly related to their socio-cultural traits, photographs, scientific inquiries, and test items. The textbooks showed numerous differences with their own characteristics, and it is expected that the children of foreign workers would face difficulties in studies taking parts in the Korean formal education. Hereupon, this study proposes the needs of development of sub-materials for the children of foreign workers adapting to schools, and reinforcement of educating teachers for understanding children, with a national plan for the children excluded from education due to problems such as an illegal residence.

This study aimed to analyze the economic feasibility of the reduction of working safety accidents in stow net fishery through the prevention education to fishing crews. The benefit was evaluated by estimating insurance payment amount that was reduced through prevention education. The decreasing rate of working safety accidents was presumed to follow the experience in Japan. The cost was assumed as the cost of textbook development. Results indicated that IRR was estimated to be 79.9% in case of scenario assuming no additional operating costs while IRR was 56.3% in case of scenario assuming 10% additional operating costs. In addition, the economic feasibility would be secured when annual operating costs increased to 274 million won according to the result of sensitivity analysis.
