  • 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.

  • This study examined the differences of academic achievement by social status types through sociometry. This study analyzed 201 students in grade 6 in S elementary school. The social status is classified by 7 (popular, average, rejected, aggressive-rejected, submissive-rejected, neglected, controversial) with academic achievement of each type as dependent variables to figure out the relation between social status types and academic achievement. To classify 5 social status types, a sociometry program developed by Ahn, Ie-Hwan (2007) was used, 2 social status types was classified with experimental condition, and its dependent variable was the score by subjects in the mid-term exam of the 1st semester in 2011. The average values of humanities courses (Korean and social studies) and natural science courses (math and science) were compared by both sexes and 7 social status types. The reference group was average group. As a result, as to male students, N type had the highest score both in humanities courses and natural science courses while C type had the lowest score in both groups. As to female students, P, N, C types had the highest score in both groups with similar range while R type had the lowest score in both groups. This result demonstrates that the academic achievement of students had relatively high relevance with social status. and also, suggestion that how teachers can do to enhance the academic achievement of elementary school students.

  • The purpose of this study was to evaluate the efficacy of basic integrative lecture course of medical college through cyber lecture. This study was also aimed to develop and implement a progressive cyber-teaching method which integrative lecture system is concerned for medical students. In this study, effectiveness of cyber lecture on the student's satisfaction, content difficulty and course management were analyzed by way of anonymous survey at the end of basic neuroscience integrative lecture course. Survey data were also analyzed with statistical tools to find out strength of correlation between students degree of satisfaction to cyber lecture and their individual grade of this course. The majority of students held positive opinions on course management, level of difficulty in each session, utilizing multimedia contents and preferred cyber lecture system to be continued in the future. Many students also suggested intimate integration of multimedia contents shown in cyber lecture to the lab sessions for the maximization of educational effect. In this study, it suggested that cyber lecture could be a useful tool in teaching integrative medical subjects and play more important role in the future integrative medical subjects with the improvement of present problems and limitations.

  • Calculus is used in various parts of human life and the basis of social science such as economics and public administration. Yet that is still considered important in the field of science and technology only, and there have been a lot of disputes on that phenomenon. Fortunately, calculus is going to be taught as part of the academic high school second-year mathematics curriculum in and after 2010. Students who face calculus for the first time should be helped not to lose interest in differentiation learning, not to be apprehensive of it nor to avoid it. The purpose of this study was to examine the types of errors made by students in the course of solving differentiation problems in an effort to lay the foundation for differentiation education. A pilot test was conducted after generalized differentiation problems to which students were usually exposed were selected, and experts were asked to review the pilot test. And then a finalized test was implemented to make an error analysis according to an error type analysis framework to serve the purpose.

  • Architecture is usually seen as a product of art and technology. However, most historical buildings also exemplify various sophisticated principles of mathematics. Outstanding examples of architecture around the world such as Seokguram, Daewoongjun of Bulguksa, Muryangsujeon of Buseoksa, and the Parthenon provide students with a great opportunity to study their underlying mathematical properties and principles. The activity of identifying and investigating such mathematical principles in historical buildings enables students to realize that mathematics is a practical subject, and thus provides justification for the study and importance of mathematics. For the purpose of this study historical architecture was reviewed with this in mind in order to develop STEAM education materials focused on elementary school mathematics. The result of this study is as follows: first of all, appropriate examples of historical architecture were selected on the basis of the 2009 revised curriculum's content and teaching goals. These involved chapters on 'proportion', 'symmetry', 'movement of figures', 'building blocks', and 'triangles'. Secondly, a meta-analysis was performed on the historical buildings that clearly illustrate mathematical principles. Thirdly, STEAM education materials focused on elementary mathematics using architectural examples were developed which made actual application in classrooms possible. And lastly, surveys of professional groups were conducted to verify whether the produced materials were suitable teaching resources.

  • We present our experience of combining, in a realistic setting, a static analyzer with a statistical analysis. This combination is in order to reduce the inevitable false alarms from a domain-unaware static analyzer. Our analyzer named Airac(Array Index Range Analyzer for C) collects all the true buffer-overrun points in ANSI C programs. The soundness is maintained, and the analysis' cost-accuracy improvement is achieved by techniques that static analysis community has long accumulated. For still inevitable false alarms (e.g. Airac raised 970 buffer-overrun alarms in commercial C programs of 5.3 million lines and 737 among the 970 alarms were false), which are always apt for particular C programs, we use a statistical post analysis. The statistical analysis, given the analysis results (alarms), sifts out probable false alarms and prioritizes true alarms. It estimates the probability of each alarm being true. The probabilities are used in two ways: 1) only the alarms that have true-alarm probabilities higher than a threshold are reported to the user; 2) the alarms are sorted by the probability before reporting, so that the user can check highly probable errors first. In our experiments with Linux kernel sources, if we set the risk of missing true error is about 3 times greater than false alarming, 74.83% of false alarms could be filtered; only 15.17% of false alarms were mixed up until the user observes 50% of the true alarms.

  • The purpose of the study was to investigate the effect of explanation in conjunction with gravity and density on students' alternative conceptions for floating and sinking phenomena. The subjects were 140 students of 11th grade in 4 classes of a high school located in Gangwon Province. We divided them in two groups; comparison and experiment. The students of experiment group learned explanation in confection with gravity and density. The students of comparison group learned explanation of pressure as represented in physics textbook. ANCOVAs (analysis of covariance) were conducted using the pretest as a covariance. In items related to characters of matter, 2 items are not significant and only 1 item has significant small effect size (Hedges' g=0.327). In the change of alternative conceptions, there is no meaningful gap between two group. However, in items related to relative weights between object and water, the all items have significant effect sizes (0.286~0.502). In addition, frequency of experiment group's alternative conceptions related to pressure decreases considerably, but comparison group does not. Therefore, the explanation in conjunction with gravity and density suggested in this study can decrease students' alternative conceptions related to floating and sinking phenomena and increase scientific conceptions.

  • The purpose of this study was to examine the knowledge of dental hygienists about the elderly and their attitude toward them as dental hygienists played vital roles in oral health care for elderly patients. It's ultimately meant to help improve their right understanding of the elderly to provide quality oral health care service to the elderly population in preparation for an aging society. The subjects in this study were 241 dental hygienists, on whom a self-administered survey was implemented. After the collected data were analyzed, the following findings were given: They got a mean of $12.40{\pm}2.99$ out of possible 22 points on knowledge of the elderly. Their general characteristics and characteristics related to the elderly made no statistically significant differences to their knowledge. As for attitude toward the elderly, they got a mean of $3.13{\pm}0.28$. Concerning links between their general characteristics and attitude toward the elderly, the better-educated dental hygienists took a more favorable attitude to the elderly.

  • After Fukushima Nuclear Accident on Mar11, 2011, to grasp the thought of university students in Korea on radiation and medical radiation and seek for the right mass communication on the radiation safety of the people and the proper teaching method on radiation, 790 questionnaires from the universities which had a four-year department of radiological science in 5 provinces(Gyeonggi, Gangwon, Chungcheong, Jeolla, and Gyeongsang-do) all over the country were collected and analyzed. The questionnaire was composed of 36 items, and it was analyzed that one of the important causes that made them feel that radiation was dangerous was 'even if they were exposed to the small quantity of radiation, they could have trouble later.' ($3.28{\pm}1.05$). In the item of the control of radiation, there were the respondents who answered that the government should take action rather than an individual($3.87{\pm}0.89$). In the item of 'Fukushima Nuclear Accident made me think that 'We should not keep nuclear power generation', the result was $2.79{\pm}0.95$. In the item of 'My thought on the medical radiation has negatively changed since Fukushima Nuclear Accident', the students who hadn't taken the course related with radiation showed a negative thought on the medical radiation, such as, there was $2.64{\pm}1.02$ as a whole, $2.31{\pm}1.00$ in department of radiological science, $2.94{\pm}0.95$ in department of dental hygiene, and $3.13{\pm}0.82$ in other departments. And also, those who thought that the education of radiation was necessary were 82.28%, and T.V or Internet was thought as the most effective teaching method.
