Life competencies most required for university students, who receive a higher education and prepare to go into society, are job competencies. People with a variety of competencies are needed in the job market in a globally-oriented 21st-Century knowledge-based society. Now that raising competent people who have a high level of job competency is regarded as one of university functions, a way to improve job competencies through university education needs to be investigated. This study proposes a convergence education system to improve job competencies. The convergence education system includes five type of convergence: convergence in major fields of study, convergence in education courses, convergence in education space, convergence in education methods, and convergence in education period. This education system is expected to improve a variety of job competencies including cognitive competencies, non-cognitive competencies, and global competencies.

There has been an ongoing symbiotic relationship between the history of the International Commission on Mathematical Instruction(ICMI) and the broader history of mathematics education since 1908. Similarly, the International Congress on Mathematical Education(ICME) has played an important role in the direction of Mathematics education since its first congress in 1969. ICME-12 is due to be held in Seoul, Korea from July $8^{th}$ to $15^{th}$ 2012. To date, there has been no research paper concerning the history of the ICMI published in any Korean journal. In readiness for the upcoming ICME-12, this paper aims to provide a comprehensive overview of the history of the IMCI from the perspective of Mathematics education.

This study demonstrated the stabilizing role of a cyclodextrin on Keggin $[PW_{12}O_{40}]^{3-}$ via hydrogen bonding complexation unveiled by ESI-MS. The distinctive fragmentation pathways of the $\{PW_{12}\}/{\gamma}$-CD complexes from that of discrete $[PW_{12}O_{40}]^{3-}$ showed that the so-called "weak" non-covalent interactions can effectively change the dissociation chemistry of POM in the gas phase. The influence of different types of solvents and organic additives such as ${\gamma}$-CD on the stability of Keggin $[PW_{12}O_{40}]^{3-}$ was also addressed firstly by ESI-MS.

The purpose of this study was to examine the relations between using experience of environmental education facilities and attitude toward environmental education in parents who have elementary students in Seattle, U.S. The findings of this study represented that elementary parents have a great understanding about the importance of environmental education. Parents have a strong agreement with the necessity of environmental education in childhood. This research also found the differences between grades and facilities for environmental education in expected effect on environmental education and desirable fields of environmental education. The awareness of the importance of environmental education increased according to frequency in using environmental education facilities. In addition, the more the experiences of using various environmental education facilities, such as museum of natural history, science museum, arboretum, and aquarium expanded, the more educational effects positively increased over time.

본 논문에서는 정보블록알고리즘(IBPA; Information Block Preprocessing Algorithm)을 이용한 정보블록 정렬알고리즘(IBSA; Information Block Sort Algorithm)을 제안하고 그 성능을 평가하였다. IBSA의 시간복잡도는 O(N)이며, 데이터의 분포상태에 영향을 받지 않는다. IBPA의 성능을 측정해본 결과, 2백만개의 랜덤데이터를 정렬한 경우, 중복 값 허용의 경우(a)는 퀵 정렬의 32.42%, 기수정렬의 9%정도의 비교회수만으로도 정렬할 수 있음을 보여주었으며, 중복 값이 없는 경우(b)는 퀵 정렬의 53.12%, 기수정렬의 12.79%정도의 비교회수만으로도 정렬할 수 있음을 보여주었다.

The recent papers [7, 12] developed two maps named by an LA- [7] and an LMA-map [12]. The present paper studies their properties and further, develops generalized versions of an LA- and an LMA-map, which makes the LA- [7] and the LMA-map [12] improved.

Currently many companies and cyber-universities are investing large amount of time and efforts to develop a standard for Web-based learning contents. Among various standards proposed, SCORM(Sharable Content Object Reference Model) has been especially interested regarding web contents and LCMS(Learning Content Management System), In contrast with corporate and adult education, many seem to be skeptical that SCORM could be applied to K-12 education. In the study, opportunities and limitations of the concept for the learning object in 'SCORM' are examined through analyzing relevant studies and cases. In addition, this study examines the learning object in the pedagogical Perspective, and derives suggestions for applying them to K-12 education.

Educational applications of big data analysis have been of interest in order to improve learning effectiveness and efficiency. As a basic challenge for educational applications, the purpose of this study is to develop a comprehensive data set scheme for learning analytics in the context of digital textbook usage within the K-12 school environments of Korea. On the basis of the literature review, the Start-up Mega Planning model of needs assessment methodology was used as this study sought to come up with negotiated solutions for different stakeholders for a national level of learning metrics framework. The Ministry of Education (MOE), Seoul Metropolitan Office of Education (SMOE), and Korean Education and Research Information Service (KERIS) were involved in the discussion of the learning metrics framework scope. Finally, we suggest a proposal for the national learning metrics framework to reflect such considerations as dynamic education context and feasibility of the metrics into the K-12 Korean schools. The possibilities and limitations of the suggested framework for learning metrics are discussed and future areas of study are suggested.

This paper reports on the main results of 3 study that compared students' beliefs, skills, and understandings in an innovative approach to differential equations to more conventional approaches. The innovative approach, referred to as the Realistic Mathematics Education Based Differential Equations (IODE) project, capitalizes on advances within the discipline of mathematics and on advances within the discipline of mathematics education, both at the K-12 and tertiary levels. Given the integrated leveraging of developments both within mathematics and mathematics education, the IODE project is paradigmatic of an approach to innovation in undergraduate mathematics, potentially sewing as a model for other undergraduate course reforms. The effect of the IODE projection maintaining desirable mathematical views and in developing students' skills and relational understandings as judged by the three assessment instruments was largely positive. These findings support our conjecture that, when coupled with careful attention to developments within mathematics itself, theoretical advances that initially grew out research in elementary school classrooms can be profitably leveraged and adapted to the university setting. As such, our work in differential equations may serve as a model for others interested in exploring the prospects and possibilities of improving undergraduate mathematics education in ways that connect with innovations at the K-12 level
