This study aims to present the necessity of 'mathematics for teacher' and advices for enhancing professionalism of mathematics teacher. Many mathematics teachers don't know formula giving roots of cubic and quartic equation which is presented as a example of mathematics for teacher, but they feel the necessity of professional knowledge like mathematics for teacher. As the role of mathematics teachers changes, professionalism in various fields is required. That is, they must be equipped with the belief and attitude as a professional and understand the content of mathematics for teacher and mathematics education theory. After all, loaming mathematics depends on the quality of mathematics teacher.

In this study, we tried to make histo-genetic analyses necessary to identify epistemological obstacles on the function concepts. Historical development on the function concept was analysed. From these analyses, we obtain epistemological obstacles as follows: the perception of changes in the surrounding world, mathematical philosophy, number concepts, variable concepts, relationships between independent variables and dependent variables, concepts of definitions.

Now in Korea, the 7th curriculum reform is underway. The main difference of the seventh curriculum compared with former curricula is that it puts much emphasis on individual difference. It is a "differentiated" curriculum. The basic directions of the 7th mathematics curriculum are as follows: 1. Offer various mathematical subjects for "Selective Educational Period" (Grades 11 and 12). 2. 30% reduction of mathematical contents. 3. The reconciliation of domain names of school mathematics. 4. The use of computers and calculators in mathematics classrooms.

It is important to manage an educational facility used by many students. The office of education has responsibility to manage public school facilities instead of most elementary, middle, and high schools. Some school or university outsources facility management and maintenance. An international school in Jeju is established by BTL (Build-Transfer-Lease) that includes construction and maintenance. This research objective is to analyze the case of facility management in the international school, and to provide improved method for school maintenance.

This study, after careful consideration on Piaget's structuralism, showed the relationship between Bourbaki's matrix structure of mathematics and Piaget's structure of mathematical thinking. This, studying the basic characters that structure of knowledge should have, pointed out that 'transformation' and to it, too. Also it revealed that group structure is a 'development' are essential typical one which has very important characters not only of mathematical structure but also general structure, and discussed the problem that learners construct the group structure as a mathematical concept.

In order to serve effective teaching and teaming environments with an appropriate harmony of hard technologies and soft technologies and to contribute to multimedia contents design and development this study shows that the theoretical backgrounds, producing backgrounds, contents scenario, and related research as well as their use and integration into realistic classroom. In our environments, it is believed that it is possible for us to develop effective mathematics educational multimedia development fitting to our culture and emotion. Thus it is urged that the government should support the professional multimedia development ＆ production association enthusiastically.

Edutainment refers to the form of entertainment designed to educate as well as to amuse. It typically seeks to instruct its audience by embedding messages or educational contents in some familiar form of entertainment such as computer games, films, websites, multimedia software, etc. The purpose of this study is to identify the determinants of attitude toward online game-based edutainment. This study proposes the attitude, fun, usefulness, social interaction, challenge, and educational story as major research variables, and collected the survey responses from game players having experiences with online game-based edutainment. Factor analysis confirmed that 19 questions can be categorized into 6 factors : attitude, fun, usefulness, social interaction, challenge, and educational story. Regression analysis shows that fun, usefulness and educational story significantly and directly affect the attitude toward these edutainment games, and that educational story influences the level of usefulness. In addition, challenge and social interaction were found to have significant impact on fun. In conclusion, the wider implications of the findings for utilizing online game-based edutainment are provided.

Purpose: To examine the levels of the disease-related knowledge and educational demands of pre-dialysis, chronic renal failure patients at different GFRs and stages. Methods: This study used a cross-sectional survey and aimed at 116 pre-dialysis, chronic renal failure patients, who were registered and received regular treatment from December 1 to December 31, 2009 at the nephrology departments of tertiary medical centers in Seoul. Stages were classified into Stage 3, 4 and 5 depending on GFR ranges. To measure the levels of knowledge and educational demands, the tool, which were first invented by Young Ae Lim (1996) and then modified by Hyo Sun Lim (2005) to adjust the knowledge and educational demands measuring tool for hemodialysis patients to pre-dialysis patients with chronic renal failure, was used. Collected data was analyzed with the SPSS WIN 12.0 program (average, standard deviation, Pearson's correlation coefficient, t-test and ANOVA). Results: There was a significant difference in the disease-related knowledge levels of the subjects at each stage (F=24.41, p=.000). The Scheffe post hoc test confirmed that patients at higher stages had higher levels of knowledge of their disease. Also, although the results showed that patients at higher stages had higher educational demands, there was no significant difference among the groups (F=1.259, p=.288). Conclusion: As patients have different levels of knowledge of the disease and educational demands depending on their stages, it is important to develop and use a systematic education program that reflects the demands and levels of patients at each stage in order to help pre-dialysis patients with chronic renal failure with self-management and improve their quality of life.

Socio-economic polarization in Korea partly due to recent globalization and industrial restructuring could reduce social mobility significantly through passing down educational achievement to one's children. Under the notion that residential segregation is geographical frame for the reproduction of educational inequality, this research investigates residential segregation by educational attainment and neighborhood disparity with a case study of Seoul. The statistical analyses employed local segregation measures such as Location Quotient and Local Moran's I and a variety of variables that reflect neighborhood characteristics. As a result, it found that there are sharp and clear contracts between low- and high-educational group concentrations/clusters particularly in terms of housing characteristics and educational facilities. This results provide some evidences that support the arguments about the causes of residential segregation by class in Korean Cities.

This study suggested appropriate media educational model for the Korean situation based on the two previous research results concerning Korean media mental model which have abstracted from elementary schoolers and parents respectively living in and around Seoul. This looked through typical media educational model being in effect in Western countries such as Buckingham's creation-centered model, Hobbs' action-centered model, Potter's analysis-centered model and Vanhoozer's worldview-centered model, synthesized all the strengths of each model, and finally modified and reorganized this new model to reflect demanders' needs. Newly developed demander-centered educational model is a kind of circulation model consisting of a chain of the steps: worldview and viewpoints, use(access), analysis and evaluation, reflection, and social act; Each step borrowed the essential contents of each domain of objectives and tried to reflect the specific situations for Korean demanders. The needs for media use etiquette against addiction and cyberbullying were applied to the step of 'worldview and viewpoint', the needs for the educational status of books as media to 'use(access)', and the reality of highly used digital media to 'social act.'
