Purpose: This study aims to discover the relation between the sleep duration and quality of adolescents and their body mass index. Methods: The study used data obtained through the 2009 online survey on adolescents health behaviors, targeting a total of 75,066 middle and high school students (39,612 of male students and 35,454 of female students). We first performed t-test, ANOVA and Scheffe's test and then the potential variables which was possibly related to the body mass index are determined from the tests. Using the potential variable, we performed the multiple regression analysis to finally identify the relation between the duration and quality of sleep. Results: As a result, the 39.8% of male students and the 46.5% of female students most frequently respond that the sleep duration was less than 6 hours, and 36.4% of male students and the 45.3% of female students respond that the quality of sleep was not good enough. The body mass index of both the male and the female students portionally decreases to their sleep duration, but the better quality of sleep makes their body mass index higher. Conclusion: In conclusion, the body mass index has some notable relationship with the sleep duration and quality for adolescents. It is advised to consider the sleep duration and quality in the business plans for adolescents in order for the prevention of their body mass index.

This paper focuses on the emerging patterns of educational mobility and unskilled labor migration from Uzbekistan to Japan and South Korea. Labor migration and educational mobility are becoming the next "horizon" in the expanded relationship between East and Central Asia, powered by several factors, including the efforts by Japan and South Korea to build "original" people-oriented policy engagements with the region and the demand from Central Asian states, such as Uzbekistan, to provide more labor opportunities to their young and growing populations. This paper presents the initial findings of a pilot survey that explores and occasionally compares the experiences of Uzbek migrants to Japan and South Korea, using datasets of face-to-face interviews related to various aspects of life in Japan and South Korea. The interviews were conducted face to face and online (Telegram, Skype, etc.) with 66 migrants and Japanese language school students (whom this paper treats as labor migrants masquerading as students) in Japan from November 2019 to January 2020 as well as online with 30 laborers and students in South Korea from August to September 2020.

The purpose of this research was to perform a comparison of face-to-face and blended learning of TOEIC to see if there is a difference in their learning effectiveness. The research compared the improvement rate of the students' academic achievement, their self-evaluation results, and their participation rate and results of the online assignment by using t-test, pearson correlation analysis, and regression analysis. The research results demonstrated that the blended learning is pedagogically more effective than the face-to-face although the difference is not large. It was analyzed that the results were largely thanks to the following facts: In the blended learning, the students could interact with their instructors face-to-face in the off-line class, they got the weekly text message to encourage them to participate in the online class, and their routine online class attendance could cause their more positive participation in the online assignment.

As a result of the this exploratory study the main results show that the factors affecting the satisfaction of non-face-to-face class learning of graduate students in Education were social presence, perceived easy to use, and information service quality. Secondly, the factors affecting the learning persistence were perceived usefulness and social presence, but perceived usefulness's influence was relatively small. Next, it was found that the subjective satisfaction of graduate students of education did not significantly affect their intention to continue learning persistence. Lastly, learning satisfaction and learning persistence had a positive effect on the intention to recommend to others. Through the this empirical analysitics study it demonstrate the factors such as attitudes, feelings, and friendliness toward non-face-to-face online classes perceived by graduate students in Education.

For female students, those who answered they had intention to suicide had significantly lower quality of sleep than those who answered they did not have, but for male students, there was no significant relations between them. There were no significant relations between sense of dispair and sleep quality both for male and female subjects. Conclusion: Factors of mental health related with sleep quality were stress and intention of suicide. The more they had stress and intention of suicide, the significantly lower sleep quality was.

Purpose - This paper discusses cross-cultural management (CCM) in China and how its business students get prepared by university cross-cultural management courses for an international market. Research design, data, and methodology - It was therefore decided to do an online content analysis looking at CCM courses offered by a number of Chinese universities first, and second to conduct a quantitative survey on CCM courses as well as topics among Chinese undergraduate business students at a large Eastern Chinese university. Results - From fundamental aspects, seven Chinese cultural standards emerge which highly influence the behaviour of the Chinese. There is a tendency to imply the integration of not only local but also cross cultural issues in academic management courses. Besides Hong Kong, there are currently 17 Chinese universities and schools accredited by the Association to Advance Collegiate Schools of Business (AACSB) that explicitly requires cross-cultural management competencies in undergraduate and graduate degree programmes. In addition, the study confirmed that two-third of the sample (Chinese undergraduate business students) had taken cross-cultural management courses. Conclusions - The results of this research have made it clear that Chinese universities and schools are aware of the importance of cross-cultural management competencies.

This study explored the development and utilization strategies based on the recognition of Massive Open Online Courses(MOOC) of students and professors who are the subjects of university teaching and learning. All members of the university recognized the basic concepts of MOOC as openness, sharing, and participation positively. In the understanding and recognition level of MOOC, undergraduate and graduate students were very low but professors were relatively high. They wanted the MOOC to develop courses in the humanities, natural sciences, social sciences, technology engineering and the arts and sciences, aiming at innovation in college curricula and diffusion of unique contents. The undergraduates wanted MOOC to be able to complete the liberal arts curriculum, basic learning in other areas and extra-curriculum and the graduate students who were lifelong learners wanted MOOC to be developed and utilized for strengthening lifelong education of local citizens. Professors who are providers of high quality education and lifelong learners wanted MOOC to be used for the deepening of their major courses in order to innovate the university education and to spread unique contents. The university should support the development of various MOOCs, establish the completion system, and provide advanced and high quality online education service.
