Ontology merging describes the process of integrating two ontologies into a new ontology. How this is done best is a subject of ongoing research in the Semantic Web, Data Integration, Knowledge Management System, and other ontology-related application systems. Earlier research on ontology merging, however, has studied for developing effective ontology matching approaches but missed analyzing and solving methods of problems of merging two ontologies given correspondences between them. In this paper, we propose a specific ontology merging process and a generic operator, T-MERGE, for integrating two source ontologies into a new ontology. Also, we define a taxonomy of merging conflicts which is derived from differing representations between input ontologies and a method for detecting and resolving them. Our T-MERGE operator encapsulates the process of detection and resolution of conflicts and merging two entities based on given correspondences between them. We define a data structure, MergeLog, for logging the execution of T-MERGE operator. MergeLog is used to inform detailed results of execution of merging to users or recover errors. For our experiments, we used oriental philosophy ontologies, western philosophy ontologies, Yahoo western philosophy dictionary, and Naver philosophy dictionary as input ontologies. Our experiments show that the automatic merging module compared with manual merging by a expert has advantages in terms of time and effort.

This study aims to answer the research question of what are the global leadership competencies(GLC) and what is the integrating framework of GLC? To attain the goal of reframing the GLC models with systematic research on GLC, the specific objectives are delineated as follows; the first objective is to identify the area of GLC. The second one is to extract the dimensions agreed with consensus. The third one is to suggest the reframed GLC model. Through the literature review and content analysis about GLC and global mindset, the two dimensions-subject and objects-of GLC model are emerged to classify the existing clusters of GLC. The extracted objects are self, others, culture, business, and global world. The dimension of subject who is global leader is more specifically divided into the knowing/doing process and three aspects of human activity like cognitive, emotional, and behavioral one. GLC are reframed and rearranged based on the two dimensions. As a results new framework for GLC with 11 clusters are presented. Knowing group of GLC contains personal, social, cultural, business literacy, and global mindset. Doing group of GLC contains personal, social, cultural, business savvy, and global change. Personal traits as a core character are at the core of the knowing and doing process of the self. Lastly, the implications and limitations of this research are suggested, and suggestion for further research is followed.

Modern geography in France since the end of 19th century was begun with regional geography. France after losing the Franco-Prussian war in 1871 had tried to regain the deteriorated national proudness through the colonial expansion. The social and historical contexts in France had encouraged French geographers to engage in detailed small area studies. In particular, after Blache became a faculty at Sorbonne University his idea on integrative rather than selective description on area studies had gained paradigmatic popularity not only in geography but in other disciplines. The regional geography tradition was then firmly established as a science and as an art by Vidalian school until the beginning of Second World War. However, when industrialization and urbanization were the dominant science since the 1950s spatial analytic geography has become popular research tradition replacing the previledged regional geography. Nevertheless, geography in France is still acknowledged as an interesting and valuable discipline since regional geography tradition had accumulated rich knowledges on various regions. As regional geography provides valuable information and helps to understand various world regions, it should be regenerated as a research tradition which are able to fulfill societal needs accruing nowadays. By doing this, geography can rectify its disciplinary identity which has been disintegrated internally by giving too much emphasis on specialties, and melding into nearby disciplines. Our geography education for the chorography in particular focuses mainly on the listings of simple geographic facts, in this regard. Rather than attracting students' concern and motivation, geography is considered as a subject oriented toward simply memorizing geographic facts. To overcome these problems, regional geography should be discussed openly and popularized in research. Regional geographic methods available and results produced in other countries should be introduced, and critical assessments should be made for selective acknowledgment for nurturing our regional geography.

This study, as an attempt to integrate mathematics and information for convergence education, was conducted to develop teaching-learning materials on mathematics education combined with coding education, which has recently been emphasized. We chose the subject of digital signature for coding education, and used SageMath as a coding program. In this study, we overview mathematics used in the elliptic curve digital signature algorithm, one of the many methods for digital signature, and developed the teaching-learning materials on the algorithm for mathematics education integrated with information education based on coding. The elliptic curve digital signature algorithm utilized in transactions of Bitcoin, which many people recently are interested in, is a good example, showing students that mathematics is applied to problem-solving in the real world and provides an optimal environment for implementation by coding. Accordingly, we expect that a class on algorithm will provide a specific teaching-learning program to achieve the goal of integrated mathematics education. By comprehensively considering the opinions of mathematicians, mathematics teachers and mathematics education experts, we expect that the teaching-learning program will be realized as a meaningful class in science high schools, high school's math clubs, and 'number theory' class in colleges.

Development of portable device measuring the vital sign continuously with no limit of time and space is absolutely prerequisite for the U-health care that grafts the ubiquitous concept into medical system. Accordingly, it requires to develop a garment style apparatus for measuring vital-sign that is easy to wear on for a long time period. This study suggests a method to improve the insulation of electric cable and the skin adhesion of electrode by integrating the electric conductive material to garment, in order to develop a garment apparatus for measuring ECG for U-health care. Results of the research are as follows; In order to provide the adjacent conductive yarns with insulation, braid with narrow woven end was interlaced using polyester yarn. As a result, the direct contact between electric conductive yarns was restrained, which would be interposed into pin-tuck structured cable. Washable silicone gel applied around the electrode made of electric conductive fabric improved the adhesion, which prevents electrodes from dropping off from the skin surface during body movement. ECG signals on the human subject were tested using the garment apparatus developed by the above method. And the result was that the clear QRS wave formation in the typical form of ECG could be measured in both conditions of still and moving state as well. The result of this study is expected to contribute for the production of U-health care related medical apparatus by accelerating the practical uses of the garment measuring vital sign at a reasonable price.

A lot of educators claim that the open education should be performed in elementary classroom, but it is true that they do not suggest the specific direction of practicing open education in case of mathematics subject. Although a project lesson is recommended, there is little case that suggests the direction of practice and the evaluation method of project lesson. Therefore this study searchs for the possibility of practicing open education in elementary mathematics classroom by reviewing the portfolio assessment and suggesting the specific case of applying the portfolio assessment to project lesson. A portfolio is a folder in which is recording solution process, student's self reflection, and teacher's comment, about topics and problems more than one. Students can see their own varying aspects and recognize their own merits and demerits, sincerities, and potentialities by portfolio assessment. Futheremore, teacher can both grasp the student's cognitive situation and give them the professional advice about the cognitive development. That is, they can perform the instruction underlining the learner's ability and personality, by identifying what Vygotsky calls 'the proximal zone of development' through portfolio assessment. Consequently, portfolio assessment is an alternative evaluation method for integrating process and product of learning, and can be used as an important tool for developing the learner's potential possibility of self-realization.

In the field of 'Human Vibration', it has been interested subjects to make equal sensation curves related to translational and rotational direction of whole-body, hand-transmitted and head-transmitted vibration, etc. When we consider the vibration of a vehicle, the main factor is vertical whole-body vibration. Until now, most of equal sensation curves used to derive frequency weighting function had been made using Western people. However, because of the inherent differences (for example, characteristic and shape of body parts, muscular and cellular tissue) between the Western people and the Oriental people, equal sensation curves based on Oriental people might be required. Also, the weight differences between the samples which consist of average-weighted and over-weighted group might cause the difference of equal sensation curves. So, in this study, 20 male Korean people were used to find equal sensation curves subject to vertical whole-body vibration on seated posture. Among 20 males, an over weighted group consisted of 10 male persons and an average weighted group was the others. Integrating and analyzing the data of two groups, some of non-parametric tests such as 'The Wilcoxon Signed Rank Test' and 'The Mann Whitney U test' were used.

The purpose of this study was to explore practical meanings of convergence education and to seek ways of implementing it in school science education. The study adopted focus group interview method in order to elicit science teachers' perceptions and practical knowledge related to various ways of integrating educational aims and contents from the perspectives of science education. Two focus group interviews were held with four science teachers with the themes of the concept and potential of convergence education, and the implementation and systemic support, respectively. The qualitative data was analyzed by deriving major themes comprising teachers' perception on convergence education: they are 1) related concepts and rationales, 2) contents, methods, and assessment, 3) the characteristics of the science subject that make it suitable for convergent education, 4) teacher perception and professionalism required for implementing convergent education, and finally 5) environmental conditions for putting the idea into practice. Based on this result, the study discusses conceptual and practical issues for implementing convergence education in ways that contribute to overcoming the problems of the traditional educational system and reorienting science education towards the future society.
