This study starts with the idea that Korean mathematical word 'byon' which means 'side' of polygons or angles is very ambiguous. The purpose of this study is to make the concept and range of 'byon' clear and to suggest the ideas which can help children understand the concept of 'byon'. For this, various dictionary and the past Korean mathematics curriculums are reviewed. As a result, two attributes 'byon' has are identified and some reasons which block children from understanding 'byon' are detected in its introduction method of mathematics text books and inkhorn of the mathematical term. Finally, two different ideas for helping children understand the concept 'byon' are suggested based on the conclusion of this research.

Three Eum and Three Yang[三陰三陽] is a way of studying the changing of nature from a Eum(陰) and Yang(陽) point of view, Juhakhae(周學海) divides this into two dimensions. The first is the concept of dividing the exterior part of the body excluding the organ into 6 divisions as Eumyang(陰陽) of front and rear characteristic. The second is the concept of dividing the systematic bio-activity of the central organ into another 6 dimensions. The former concept is illustrated in the body as a certain meridian controlling a certain field of the body, while the latter is presented as a certain organ performing an activity of Gi(氣). Three Eum and Three Yang[三陰三陽] is not based on fixed substances. but it is a thought process model of observing the structural-functional changes of the body in disease state. Therefore, by understanding Three Eum and Three Yang[三陰三陽] of field and activity of Gi(氣) respectively and comprehensively putting these into practice, we will be able to approach the essence of the disease state in a more precise manner.

Objectives: Humans experience the process of separating-individuating themselves from an object via the conflict between dependence and independence within the self. The separation-individuation theory focuses on the psychological process of individualizing oneself. Although adolescents' individuation from their parents is based on intrapsychic events, there is an increasing need for an intersubjective understanding of it. We applied intersubjectivity to adolescents and parents to interpret and find solutions for problems arising during their individuation process. Methods: This study retrospectively reviewed a case of a son and his father treated by the author. From the study subject, contents that represent adolescents and parents' interaction and separation in the individualization process were extracted and analyzed, and their experiences shared in this process were reconstructed from the therapist's perspective. Results: From the case involving an adolescent boy with conduct problems and his interactions with his father, the authors observed the phenomenon of intersubjectivity and proposed the concept of "synchronized individuation" between adolescents and parents. As adolescents rapidly grow and change, they experience various dynamic interactions with their parents. Through learning to tolerate the conflicts and ambivalent tension inherent in this individuation process, adolescents and their parents develop their new identity. Conclusion: "Synchronized individuation" should be understood as complementary to, rather than exclusive from, the existing concept of the separation and individuation. It offers a new paradigm with which to understand adolescent-parent conflicts in the process of separation-individuation.

Purpose: Research ethics has social implications beyond the issues of personal morality and research integrity. In recent years, research ethics has become a more controversial topic in society. In this study, the concept of the university research ethics curriculum is defined, the current status of the research ethics curriculum is analyzed, and the direction of the university research ethics curriculum development direction is discussed. Research design, data and methodology: The concept of university research ethics education and the current status of research ethics education were examined, and the development direction of the university research ethics curriculum was explored based on the framework . Results: field education to secure university research ethics is still insufficient. In other words, only 12 universities for undergraduate programs and 37 universities for graduate programs included research ethics in their regular curriculum. Conclusions: The occurrence of research misconduct is mainly caused by not recognizing the error or not taking it seriously. In particular, university research misconduct results from a lack of understanding of research ethics, poor research education, a performance-oriented academic climate, and the absence of an institutional system for establishing research ethics.

As the concept of Ubiquitous Computing has become an important issue, we need to have a voice in the field of Transportation. Ubiquitous Computing means that IT network based on realization of 5 Any(Anytime, Anywhere, Anything, Anynetwork, Anydevice) is deeply penetrated into our daily life. As ITS has developed with the aid of IT and Transportation Technology together, we need to discuss u-Transportation concept with Ubiquitous Computing and Transportation Technology. According to the recent papers and studies, Transportation or Transportation Information sector is mentioned as a major application of Ubiquitous Computing. However, most of the studies are limited to the basic concept without any in-depth understanding about Transportation. This paper present the implementation of u-Transportation and the role of Transportation Technology based on recent technology trend.

In this study, the influences of the context of discrepant events on the conceptual change process using cognitive conflict strategy were investigated in terms of students' cognitive and motivational variables such as cognitive conflict, situational interest, attention, effort, conceptual understanding. A preconception test was administered to 536 seventh graders. A test of response to a discrepant event and a situational interest questionnaire were then administered. The context of discrepant events, either scientific or everyday, was randomly presented to the subjects. After learning the concept of density, the tests of attention, effort, and conceptual understanding were administered. The reponses of 194 students who had been found to possess the target misconception were analyzed. The results revealed that the scientific-context discrepant event induced higher cognitive conflict than everyday-context one. The context of discrepant events, however, did not show significant correlations with situational interest, attention, effort, and/or conceptual understanding. The result of path analysis indicated that the context of discrepant events both directly influenced cognitive conflict and indirectly influenced conceptual understanding via cognitive conflict.

Taking samples of data and using samples to make inferences about unknown populations are at the core of statistical investigations. So, an understanding of the nature of sample as statistical thinking is involved in the area of statistical literacy, since the process of a statistical investigation can turn out to be totally useless if we don't appreciate the part sampling plays. However, the conception of sampling is a scheme of interrelated ideas entailing many statistical notions such as repeatability, representativeness, randomness, variability, and distribution. This complexity makes many people, teachers as well as students, reason about statistical inference relying on their incorrect intuitions without understanding sample comprehensively. Some research investigated how the concept of a sample is understood by not only students but also teachers or preservice teachers, but we want to identify preservice secondary mathematics teachers' understanding of sample as the statistical literacy by a qualitative analysis. We designed four items which asked preservice teachers to write their understanding for sampling tasks including representativeness and variability. Then, we categorized the similar responses and compared these categories with Watson's statistical literacy hierarchy. As a result, many preservice teachers turned out to be lie in the low level of statistical literacy as they ignore contexts and critical thinking, expecially about sampling variability rather than sample representativeness. Moreover, the experience of taking statistics courses in university did not seem to make a contribution to development of their statistical literacy. These findings should be considered when design preservice teacher education program to promote statistics education.

'Transference phenomenon' is considered as a essential feature in psychotherapy as well as psychoanalysis. But there is much difference in conceptual and methodological issues for 'transference phenomenon' among various psychoanalytical schools. In general, the depth psychological studies for 'transference phenomenon' are mainly from the psychoanalytical view of point but relatively sparse from the analytical psychological view of point which has more holistic and deeper understanding for human psyche. So this article was intended for a comprehensive review of 'transference phenomenon' from the perspective of analytical psychology and tried to make an understanding for its meaning. To begin with, the concept of 'transference phenomenon' was investigated from the view before Jung and after Jung, with Jung's view in the center. Then it was made clear that 'transference phenomenon' from the perspective of analytical psychology could be understood by several characteristic aspects. It was suggested that a careful study on the symbolic meaning of the woodcuts' pictures in Rosarium Philosophorum including a proper interpretation of its posterior part to which Jung didn't refer in "The Psychology of The Transference" be devoted to the genuine understanding of 'transference phenomenon' from the perspective of analytical psychology afterwards.

We are able to analyze a social or a natural phenomenon by using the conception. if we understand a concept of an object. However it is not easy to understand a concept of an object. The process of comprehending the concept is a long rigorous mental journey. Hence, understanding concepts has been emphasized in studies in education. Previous studies demonstrate that conception has a dual nature, which has both an operational and a structural nature. We are able to acknowledge that structural conception develops from an operating conception. Nevertheless, discovering a dual nature of conception and knowing whether students acquired the dual nature, especially the structural nature are difficult to achieve. In this research, I examine the operational and the structural nature of a center of mass conception and analyze whether students acquire structural nature of the center of mass conception, and find implications which we would do to build the structural conception on a concept.

The goal of the study was to examine undergraduate students' perception of the importance of the concept of system in science. The participants are six undergraduate students in the department of science education. Data sources included interviews and interview notes. Results showed that students understood the concept of system as a group of objects, space, and boundaries, which differed from a previous research study about its details. The students also were able to explain the concept of system related with the process of problem solving. The students recognized as well the selection of system for analysis of natural phenomenon, explaining that the selection of system was determined by purpose of the observer. Lastly, the students explained that the concept of system was useful for science learning because it was strongly related with other science concepts, understanding of interactions, and learner's cognitive development.
