The existence of mathematical objects was considered through diorism which was used in ancient Greece as conditions for the existence of the solution of the problem. Proposition I-22 of Euclid Elements has diorism for the existence of triangle. By discussing the diorism in Elements, ancient Greek mathematician proved the existence of defined object by postulates or theorems. Therefore, the existence of mathematical object is verifiability in the axiom system. From this perspective, construction is the main method to guarantee the existence in the Elements. Furthermore, we suggest some implications about the existence of mathematical objects in school mathematics.

Mobile learning is a practical learning method for busy adult learners because the mobility of digital devices can overcome the drawbacks of e-learning. However, research is strongly lacking in the theoretical exploration of mobile learning effects and functions and its empirical research. Moreover, the research of learning characteristics and learners' requirements must be considered before applying and disseminating mobile learning into the educational field. To address this shortcoming, this study conducted an online survey with 1,542 officers of the Ministry of Health and Welfare Affairs (MHWA) regarding learner recognition to mobile learning. The analysis of learners' attitudes toward mobile learning, based on age and position, indicated that subordinate workers appeared to place more value on mobile learning. Many participants preferred mobile learning because of its mobility and the effectiveness of anywhere and anytime. However, some participants continue to misunderstand mobile learning and its necessity. Therefore, consideration of learning effectiveness, the form of the content, and learner-centered learning must be reviewed in advance. This study could lead to practical implications of mobile learning.

As globalization accelerates and the trade environment rapidly changes, a more prepared trade workforce is required for the business world. The trade department is an important educational institution that educates and trains future trade talent. Thus, in the evolving trade environment, their role has significant implications for the economic growth of Korea. The present paper is a comparative study of the importance of the university education system in terms of the trade work force through the Person-Organization fit (P-O fit) perspective. We observe that the American trade education system is more oriented to meet and reflect the needs from the real world. It contains a support structure through various governmental organizations that offer financial incentives as well as educational opportunities through internships and other hands-on experiences. The trade education systems in universities in Korea are still static by comparison and are recommended to implement changes that will give students more practical exposure to trade. The governmental and business sectors are also encouraged to support universities in achieving these goals through building a strong cooperative network with university trade departments.

The purpose of this study is to examine the satisfaction and needs of mothers living in J innovation city with the child-rearing environment. A survey was conducted on 223 mothers with young children. The results are as follows: First, parents' needs on all items of economic, social and physical child-rearing environment were higher than their satisfaction on the items. Second, according to the reasons why parents are moving to J innovation city, there were significant differences between groups in their educational environment among subcategories of the economic and physical child-rearing environment. Third, according to the residential area they previously lived in, there were differences between groups in their child-rearing environment, such as the conditions of house location and educational environment among subcategories of the economic and physical child-rearing environment. The limits and implications for the administrational support for building a hopeful child-rearing environment in an innovation city were discussed.

This study was to examine science learning motivation of primary students participating in science museum educational programs. The subject was 36 primary students in the programs in a science museum during a month. The questionnaire for this study consisted of items developed by us and some items from Motivated Strategies for Learning Questionnaire developed by Pintrich et al.(2001). The results included primary students' motivation of joining the programs in a science museum, their perceptions about the programs, and the effects of the programs on their science learning motivation. It seemed that the students had the opportunities of doing science activities in the museum on the recommendation of their family or teachers, especially their parents. And they were motivated to participate the programs with interests of science and they were interested in the activities in the programs. The statistics showed that the program have an positive effects on the students' self efficacies and values on science tasks. Based on this results, discussion and implications were presented.

This article intends to review what problems the terms in calculus have and how those problems are caused. For this purpose We make examinations on the considerations in the analysis of mathematical terminology, which includes the problems of general and technical terms, the meaning and the boundary of words, their consistency, the name and meaning, concept and their concept images, translations and qwerty effects. And in chapter 3, We analyse the textbook which are currently used, through which I was able to find out that the terms in calculus have some problems, In other words, the key terms such as "differentiable", "differential coefficient", "differential" have their roots in the term "differential" but the term "derived function" is very distinct from other terms and thus obstructs the consistency of terms. And the central term "differential" is being used without clear definition. In particular, the fact that "differential", when used in its arbitrary definition, has the image of "splitting minutely" can be an obstacle to understanding the exact concepts of calculus. In chapter 4, We make a review on the history of calculus and the term "differential" currently used in modern mathematics so that I can identify the origin of the problem connected with the usage of the term "differential". We should recognize the specified problems and its causes and keep their instructional implications in mind. Furthermore, following researches and discussions should be made on whether the terminology system of calculus should be reestablished and how the reestablishment should be made.e terminology system of calculus should be reestablished and how the reestablishment should be made.

China becomes more and more important for Koreans in political and social aspects as well as in educational aspect. However, there hasn't been any study regarding the mathematics curriculum of China. Thus, it is necessary to introduce the recent mathematics curriculum of China, compare the curriculum of China with that of Korea, and find the features of the curriculum. Several characteristics of the mathematics curriculum of China were identified; 1) mathematics strands were combined, 2) condensed and linear structure of contents, 3) providing examples for mathematics topics stated in the curriculum, and etc. Based on these characteristics, some implications were elicited for the next mathematics curriculum revision in Korea.

This study analyzed how two sixth graders recognized, generalized, and represented functional relationships in exploring geometric growing patterns. The results showed that at first the students had a tendency to solve the given problem using the picture in it, but later attempted to generalize the functional relationships in exploring subsequent items. The students also represented the patterns with their own methods, which in turn had an impact on the process of generalizing and applying the patterns to a related context. Given these results, this paper includes issues and implications on how to foster functional thinking ability at the elementary school.
