The concept of 'cultural diversity' has emerged as a key concept and the buzzword of the 21st century's international community in education, science and culture sectors since UNESCO's "World Declaration on Cultural Diversity"(2001). However, the appropriate and correct implementation in educational level and in a subject scale can not be pursued without special understanding of multilateral implications of UNESCO's 'cultural diversity' because the concept of cultural diversity has been distributed to various applications according to individual scholars and institutions before the "World Declaration on Cultural Diversity" was released. The ultimate orientation of 'cultural diversity', the concept presented in "World Declaration on Cultural Diversity" is 'world peace' and 'the coexistence of various cultures of mankind'. In this regard, 'cultural diversity' has special 'educational' meaning to the next generation as well as the current one. Also, it is meaningful to take educational practices on cultural diversity in case of the "World Geography" subject in view of that international society of geographical education came up with "International Declaration of Geographical Education for Cultural Diversity" in the IGU(International Geographical Union) 2000. From this point of view, the author proposes that the 'cultural diversity' concept implies four folds of meanings as an ideology, as a symbol, as a vision, and as a epistemological turn based on the analysis of literatures on 'cultural diversity' of UNESCO, then presents an educational practice centering around the examples and its usage of teaching materials of cultural diversity.

In the era of the 4th industrial revolution, the development of information technology brought various benefits, but it also increased social interest in privacy issues. As the possibility of personal privacy violation by big data increases, academic discussion about privacy management has begun to be active. While the traditional view of privacy has been defined at various levels as the basic human rights, most of the recent research trends are mainly concerned only with the information privacy of online privacy protection. This limited discussion can distort the theoretical concept and the actual perception, making the academic and social consensus of the concept of privacy more difficult. In this study, we analyze the privacy concept that is exposed on the internet based on 12,000 news data of the portal site for the past one year and compare the difference between the theoretical concept and the socially accepted concept. This empirical approach is expected to provide an understanding of the changing concept of privacy and a research direction for the conceptualization of privacy for current situations.

Recently, there have been studies about Typically- Perceived-Situations (TPSs) and about critical examples as a way to understand students' preconceptions with context. TPS is a situation arising immediately in one's mind when he or she thinks about the concept, while a critical example is an example that becomes the most helpful in learning the concept. We might explore how the context is involved in the process of students' conceptual understanding by examining TPSs and critical examples together. This study analyzed, through questionnaires and interviews, the characteristics of TPSs and those of critical examples that secondary students hold about 'force' and 'mechanical energy conversion.' Students' TPSs and critical examples showed different characteristics according to the concept. In a case of force that is related to everyday life, there were various situations as TPSs and critical examples. Unlike force, there were a few situations as TPSs and critical examples such as a falling ball in the case of mechanical energy conversion. Students tended to regard situations that are usually experienced and understood easily as TPSs or critical examples. On the basis of the results of this study, it is concluded that it would be a good strategy to teach science concepts for teachers to start with the TPS of a concept, to introduce the concept, and then to expose the attributes of the concept with critical examples.

Understanding the biopsychosocial model of illness is crucial for any meaningful advance of health. The maintenance and promotion of health is achieved by different combinations of physical, mental, social and spiritual well-being. Health is not an objective of living. It is not only a state, but also a resource for everyday life. Health is a positive concept that emphasizes personal and social resources, as well as physical capacities. Understanding the biopsychosocial model of health and disease is very important in the medical system. George Engel challenged the medical profession to reconsider a strict biomedical approach to medical education and care, and to embrace a "new medical model," the biopsychosocial model. He argued that humans are at once biological, psychological, and social beings who behave in certain ways that can promote or harm their health. Although understanding the biopsychosocial model of illness is important, Korea's medical system have mainly been focusing on the biomedical model of illness. I would like to highlight the importance of biopsychosocial model of illness for Korea's medical system and real clinical field according to the 20th anniversary of Korean Society of Psychosomatic Medicine.

This study investigated the effect of visual mathematics education using smartphones and immediate feedback through SNS on students' understanding of basic mathematical concept and academic achievement at the tertiary level. Researchers analyzed the test results of 214 students' mid-term and final examination in 4 classes consisted of 16 weeks' classes with two hours per week. Also their 30 questionnaire survey results were analyzed. The result reveals that classes using smartphones promoted understanding mathematical concepts and induced students' motivation and affirmative reaction. This study implies that an appropriate use of technology will support dynamic visualization of mathematical modeling and its interpretation, which enables students' active participation and deeper understanding.

The purpose of this study is to analyze the concept of the real number e and to investigate the understanding of pre-service teachers about the real number e. 28 pre-service teachers were asked to take a test based on the various ideas of the real number e and 8 pre-service teachers were interviewed. The results of this study are as follows. First, a large number of pre-service teachers couldn't recognize relation between the formal definition and the representations of the real number e. Secondly, pre-service teachers judged appropriately for the irrationality and the construction impossibility of the real number e, but they couldn't provide reasonable evidence. Lastly, pre-service teachers understood the continuous compounding context and exponential function context of the real number e, but they had a difficulty in understanding the geometric context and natural logarithm context of the real number e.

The purpose of this study was to investigate undergraduate students' preconception about the needed knowledge to understand organic reactions based on electron flow and undergraduate students' ability that understand fundamental chemical reaction based on electron flow, and was to offer pertinent teaching and learning method. For this study, 18 sophomores that majored in chemistry education of H University, were sampled. Test papers were newly developed that based on previous research. Undergraduate students' response was classified and reasons of the response were qualitatively analyzed by interview. According to the results of this study, it was found that undergraduate students had good understanding on the concept about the electron configuration of atoms and on the concepts about the needed knowledge to understand chemical reactions based on electron flow. But they didn't apply the concepts to the fundamental chemical reaction. Therefore, teaching and learning strategy that apply the needed concepts to understand chemical reactions based on electron flow to chemical reactions should be developed.

The form or interpretation of today's communication design lies in content development and storytelling to the designer. However, the understanding as well as exteriment of the mechanisms behind content creation remain an obscure concept. Particularly given the rapid development of digital technology, since the 1980s typography has been quickly transforming itself from its static state to the more dynamic'Type in Motion'. following this came the need for solid research in'Type in Motion'as the best means of presenting story content and form The previous passage has studied the effectiveness of'Type in Motion'in presenting this kind of content. Type in Motion has allowed vast developments in the methods of story presentation. It is Due that today's digital technology has given many benefits to the designer, but on the other hand, it has required a more diverse understanding of digital design. furthermore, even the designers in digital typography lack the understanding and research in'Type in Motion'not only as a mode of visual language but also of verbal language. Given this point· in hand, the entire interpretation and interrelation of story and'Type in Motion'can be considered essential, given their shaping of effective digital typography.

Gender might be interpreted in different roles and meanings depending on social and cultural backgrounds. Based on the premise that understanding of gender may change the direction of mathematics education, this paper confirmed how gender is interpreted in the preceding study of mathematics education in Korea by applying the literature research method. In particular, predictive model based on empirical perspective and gender schema model based on constructivist perspective. Based on the analysis of gender and research methods in cultural and historical composition models based on historical perspectives and postmodernism models based on postmodernism perspectives, this study analyzed trends in domestic mathematics education. As a result of the analysis, it is confirmed that gender is recognized as a biological difference in domestic mathematics education, and that analysis of gender and related elements of mathematics education is mainly used using statistical analysis techniques. This suggests that various approaches to interpreting gender's role in future mathematics education are needed. The existing mathematics education research on gender is composed in terms of gender differences. Since biology at the time did not explain this difference, however, it should now be based on the concept of gender, which is socially defined gender. Accurate understanding of gender and gender can be the basis for clearer understanding and interpretation of gender-related mathematics research.

Through the teaching experiments, we investigated a series of processes for obtaining the differential coefficient at x=0 of the exponential function $y=2^x$ based on the process of constructing the natural constant e and the understanding of it. and all of the students who participated in this study were students who had no experience of calculating the derivative of the exponential function. The purpose of this study was not to generalize the responses of students but to suggest implications for mathematical concept mapping related to calculus by analyzing various responses of students participating in experiments. It is expected that the accumulation of research data derived in this kind of research on the way of understanding and composition of learners will be an important basic data for presenting the learning model related to calculus.
