Statistics education is considered within the mathematics curriculum and, thus, can be integrated into other areas of mathematics. However, statistical concepts and thinking skills have to be considered as very different from those of other areas. It is possible to make statistics more meaningful for the learner by making definitions or explanations of concepts in textbooks more clear and consistent. In 'Math I' and 'Probability & Statistics' of the 7th curriculum, the definitions of sample standard deviation are different, which might confuse students. In this study, firstly, some issues relevant to sample standard deviation concept are discussed through the analysis in terms of didactical situation and curriculum. Secondly, the characteristics of sample standard deviation concept as a scholarly knowledge are examined. Finally, the characteristics of didactic transposition of sample standard deviation concept in Japanese, American, and British textbooks are investigated and some suggestions are elicited.

There is something common between the Korean female Kukkuk and the Japanese Takarazuka Revue in that actors are all females and love is the main theme. Some of the females should play men's roles, so they are described as ideal men and are more manly than real men, and female audiences are attracted by them. It is hard for actresses to play men's roles-they have to stretch open their shoulders, walk with long steps and produce a deep voice. They put on a makeup a little exaggeratedly to perfectly disguise themselves as men and express strong images-some red tone makeup on their face, thick eyebrows with their ends upward, thick eye lines to make eyes seem bigger and stronger, and thick side whiskers. On the contrary, a makeup for female characters is softer to highlight femininity with thin penciled hair parted and braided on the sides of the face. The Takarazuka Revue's students are divided into male characters and female ones from the regular course of music schools, and they select their roles in consideration of their height and range of voice, mainly based on their wish. In case of male characters, they need a long career and verification of ability to be the best. Females playing men's roles and showing their manliness are violation of a social custom standardizing the character of males and females and are the reverse of roles expected by a society or a culture. A world experienced by these plays is a kind of revolt breaking the taboo of the patriarchal system.

The purpose of this study was to examine the differences in the brain activation evoked by music arranged in major and minor key used with an identical motion film during the fMRI testing. A part of the audio-visual combinations composed by Iwamiya and Sano were used for the study stimuli. This audio- visual clip was originally developed by combining a small motion segment of the animation "The Snowman" and music arranged in both major and minor key from the original jazz music "Avalon" rewritten in a classical style. Twenty-seven Japanese male graduate and undergraduate students participated in the study. Brain regions more activated by the major key than the minor key when presented with the identical motion film were the left cerebellum, the right fusiform gyrus, the right superior occipital, the left superior orbito frontal, the right pallidum, the left precuneus, and the bilateral thalamus. On the other hand, brain regions more activated by the minor key than the major key when presented with the identical motion film were the right medial frontal, the left inferior orbito frontal, the bilateral superior parietal, the left postcentral, and the right precuneus. The study showed a difference in brain regions activated between the two different stimulus (i.e., major key and minor key) controlling for the visual aspect of the experiment. These findings imply that our brain systematically generates differently in the way it processes music written in major and minor key(Supported by the User Science Institute of Kyushu University, Japan and the Korea Science and Engineering Foundation).

This paper is to find out the reason why students often make mistakes with 0 during computation and to get some instructional implication. For this, history of 0 is reviewed and mathematics textbook and workbook are analyzed. History of 0 tells us that the ancients had almost the same problem with 0 as we have. So we can guess children's problems with 0 have a kind of epistemological obstacles. And textbook analysis tells us that there are some instructional problems with 0 in textbooks: method and time of introducing 0, method of introducing computational algorithms, implicit teaching of the number facts with 0, ignoring the problems which can give rise to errors with 0. Finally, As a reult of analysis of Japanese and German textbooks, three instructional implications are induced:(i) emphasis of role of 0 as a place holder in decimal numeration system (ii) explicit and systematic teaching of the process and product of calculation with 0 (iii) giving practice of problems which can give rise to errors with 0 for prevention of systematical errors with 0.

This study was performed to investigate the effects of taste preference on dietary behavior and nutrient intake. The subjects were 191 female collegians in the Gyeonggi and Gangwon areas. Data were collected using anthropometric measurements, 24-hour recall, and self-administered questionnaires. The respondents were classified into sub-groups according to taste preference: sweet taste (liked and disliked group), salty taste (liked and disliked group), sour taste (liked and disliked group), hot taste (liked and disliked group), and bitter taste (liked and disliked group). The results of this study are as follows: subjects liked, in order of taste preference, hot>sweet>sour>salty>bitter tastes. There were no significant differences in height, weight, and BMI among the groups. The sweet-taste-liked group, tended to prefer Chinese food and fast foods for eating out over the sweet-taste-disliked group (p<0.05). Subjects in the salty-taste-liked group ate faster (p<0.05) and more than those in the salty-taste-disliked group (p<0.05). They also consumed more animal fat and meat (p<0.05) than their counterparts. Compared with the sour-taste-disliked group, subjects in the sour-taste-liked group tended to select Korean food or Japanese-style food for eating out, and fruits for a snack (p<0.05). The meal size of the hot-taste-liked group tended to be more regular (p<0.05) than that in the hottaste-disliked group. Overall, there were distinct differences in dietary behavior and food choices according to taste preference. Taste preference should be considered for dietary consulting and nutritional education.

This study investigated the models of four countries' elementary mathematics textbooks in Ratio and Rate and identified how multiplicative perspectives on proportional relationships and the structure of proportion situations are reflected in the textbooks. For this, textbooks of 5th and 6th grade textbooks in Korea Japan, Singapore and U.S. are compared and analyzed. As a result, we can find multiplicative perspectives on proportional relationships and the structure of proportion situations on pictorial models, ratio tables, double number lines and double tape diagrams. Also, the development of Japanese textbooks from multiple batches perspectives to variable parts perspectives and the examples of the use with two models together implied the connection and union of two multiplicative perspectives. Based on these results, careful verification and discussion for the next textbook is needed to develop students' proportional reasoning and teach some effective reasoning strategies. And this study will provide the implication for what kinds of and how visual models are presented in the next textbook.

With the movement for complete liquidation of the part history began during participatory government, a special law for the liquidation of the past history was enacted and committees related to the past history have been established. Works related to the past history has relatively smoothly progressed even if there have been many obstacles, but as the duration for the special law reached its final point, committees related the past history came to the fork of a road. This study reflects on this reality and focuses on measures for application of the records collected by committees related to the past history and in this way, establish and selected the record information contents was established and selected. The users of the information was classified into professors, students, and history researchers and Committee for the Inspection of Damages by Compulsory Mobilization under Japanese Imperialism, Committee for the Inspection of Japan Collaborators, and Truth and Reconciliation Commission were selected for the committees related to the past history to establish the contents.

K-pop has gone through ups and downs for 30 years since it was introduced to China in the 1990s. As the trigger for the 'Korean wave', K-pop has become a business card of Korean pop culture, which is another popular culture that has culminated in China after the 'Western wave', 'Japanese wave' and 'Hong Kong.Taiwan's wave'. Its wide range of influences and long time are rare in the world, so it can be regarded as a typical example of modern intercultural communication. The paper takes 1988-2018 as the time interval, combs the process of K-pop's intercultural communication in China. Based on this theory, it can make an objective evaluation on the current situation of K-pop in China. Then this paper discusses the influence of K-pop culture on the current Chinese university students through a questionnaire survey, and puts forward some developmental suggestions from the perspective of Chinese people. In order to provide a theoretical basis and enlightenment for the study of K-pop in China.

The purpose of this study is to provide the general history of fostering dentists in Japan and introducing their new roles. This research was conducted based on the government policy report on dentists and the information published by each educational institution. Based on the collected data, the official websites were used to represent the latest statistics of the institutions. The number of dentists in Japan has increased. The government established the National Examination for Dentists to guarantee the quality of dentists. After the standards for developing questions for the national examination were established in 1985, the contents of the examination have been appropriately improved by revising the standards every four years. This improvement has required dental students to study a variety of subjects for six years at dental school. Since dentists in Japan are required to respond to various demands from the nation; the Model Core Curriculum for Dental Education was developed to teach medical ethics and abilities to ensure that dentists conduct themselves professionally. Recently, the roles of dentists have been changing in Japan. When providing dental services to older patients over the age of 65, dentists and other dental professions focus on maintaining oral functions, such as saliva secretion, bite force, tongue movement, and masticatory/swallowing functions. However, oral function-related services for children are different. In addition to providing essential dental services, dental practitioners also provide special treatment, such as oral muscle training, myofunctional therapy, health guidance, and space retainers to the child patients with developmental insufficiency in oral functions. Dentistry in Japan has undergone numerous changes over the years and has continued to offer high-quality dental health services. Thus, information gained from the Japanese experience may be helpful to dental professions in other developed countries for planning oral health measures.

The boycott of Japanese products triggered by Japan's economic retaliation has heated up the Republic of Korea. This study examined the factors affecting the boycott participation intention in 217 college students and ordinary people in their 20s and 30s. The results of the study showed that perceived egregiousness, self-efficacy, and subjective norm had a positive effect on boycott participation intention, and perceived egregiousness had an indirect effect on boycott participation intention through anger. In addition, these overall impacts were moderated by online and SNS news usage. This study is significant in providing academic and practical implications for understanding boycott phenomena by verifying various influencing factors on consumer boycott intentions and comprehensively reviewing the mediating effect of anger and the moderating effect of online and SNS news usage.
