(要約) The Conjugate Gradient Squared method (CGS) has been proposed for solving large and sparse non-Hermitian linear systems, and it is well known that the CGS method may lead to a rather irregular convergence behaviour. In this paper, a Stabilized Conjugate Gradient Squared method (SCGS) is proposed as a variant of the CGS method. Numerical experiments indicate that the SCGS method is often more efficient than the CGS method. (文献検索サイトへのリンク) ● CiNii @ 国立情報学研究所 (CRID): 1390282680743891712 (CiNii: 1390282680743891712)

This paper aims to show the current situation of international academic exchange agreements at Tokushima University (TU) in the context of Japans higher education. From the situation, breakdown, trends, and challenges of TUs international partnerships over the years, the authors show their perspectives on the vital importance of agreements are a keyway to collaborating, sharing resources, creating opportunities, promoting global understanding, and preparing students for a world where cross-cultural and international collaboration is becoming increasingly important.

4.	HoangNam Tran and Cheng-Hai Jin : Challenges in Attracting International Students to Japan, Educational Alternatives, Vol.20, 11-25, 2022. (要約) Japan is an attractive study abroad destination for international students worldwide. However, there are still challenges in attracting international students and internationalization, especially for the universities not enlisted among the top-tier universities, and universities which locate outside metropolitan areas. Despite relative advantages of quality of education, affordable cost, studentfriendly environment, and exotic region-specific culture, Japanese universities still face certainchallenges in attracting international students. We conducted a literature review to investigate challenges that may hinder attracting international students to Japan's universities. The data showed that there are challenges in maintaining academic ranking and internationalization level, diversifying the student body, securing revenues for operation, regional popularity and disparity, strengthening the supporting system, maintaining cross-cultural exchange and communication, mobilizing scholarship, supporting employment and a part-time job, online transformation, etc. that may influence the efforts for effectively attracting international students.

HoangNam Tran, Atsuko Inosaki and Cheng-Hai Jin : On Campus Support and Satisfaction of International Students: A Review of Japanese Literature, The IAFOR Conference on Educational Research & Innovation 2022 Official Conference Proceedings, 1-16, 2022. (要約) Japanese universities are popular destinations for international students. A lot of efforts have been made to provide supporting services and activities to international students such as Japanese classes, counseling and consultation, job hunting and career education, exchange events, summer school, culture experience tours etc. These activities bring satisfaction to international students, which is contributed indirectly as a pulling factor for attracting international students into Japan. However, little has been known about the approaches used by different universities for supporting international students as not many reports are published in English regarding this topic. This study investigates the variety of on campus supporting services and activities provided to international students in Japanese universities and satisfaction of international students as recipients of these services. The literature for review was mainly collected from Japanese sources using Google Scholar. Data was reviewed qualitatively by comparative analysis, comparing approaches applied by different universities with regards to the elements of 300,000 international students plan and other pull factors. The results showed specific approaches, results in providing campus supporting services by different institutions. The results also imply obstacles and potential solutions to the Japanese universities to attract international students.

HoangNam Tran, Atsuko Inosaki and Cheng-Hai Jin : Online Seminar: A Potential Mental Health Support Tool for International Students, Proceedings of The 4th International Conference on New Approaches in Education, 20-26, 2022. (要約) Since 2020, university students in Japan are exposed to the impacts of Covid-19 pandemic.Data from a survey had shown that over 50% of international students had been experiencing some kind of stress (Tran, unpublished). For supporting international students in the prolonged pandemic period, we conducted a series of Stress Prevention Seminars during 2021. These seminars were designed for students to learn simple skills that could help them to cope with various stresses. Records of the seminars, including students interactions, Q&A, feedback, emotion score (Ogawa, 2000) and final evaluation were analyzed. This presentation is aiming to show: (1) preliminary results of the seminars conducted; and (2) potential of these events for strengthening mental health status of international students during pandemic. The results showed high understanding level and satisfaction rate, as well as inreased positive emotion score. The results suggested that providing these stress prevention seminars to international students is potentially to be an effective strategy, in addition to providing individual counselingand other activities, to improving stress resilience of international students for long term.

This study investigates the factors pulling international students into Japan for higher education. Data for literature review was collected from mainly Japanese sources including research reports, review papers, statistics, and online materials, which addressing the issues of international students' mobility into Japan from 2008 until present. Data was reviewed qualitatively by comparative analysis, comparing the literature with the elements of 300,000 international students plan and the pull factors from the push-pull model. The results showed specific measures in strengthening campus internationalization, expanding international cooperation and alumni network, improving supporting services, diversifying scholarship schemes, job hunting support etc. could be considered as effective pulling factors. Moreover, while these factors could be applied effectively by some universities, it is hard for other universities to follow the same approach. The results imply obstacles to the mid-ranking public universities to attract more international students and the need to improve this situation.

HoangNam Tran and Cheng-Hai Jin : Macro Factors Determining Transition of Vietnamese International Students Mobility, The IAFOR European Conference on Education (ECE2021) Conference Proceedings, 339-352, 2021. (要約) With constant increasing in numbers of students studying abroad, Vietnam is on the way to become one of the largest contributors to the world's international student mobility. The overall picture was changed from several thousand students sent to the Eastern bloc during the cold war to about 200,000 students currently studying in Japan, Australia, US, Europe etc. This paper reviews the factors that affect the transition of trends and mobility of Vietnamese international students in the modern time. By examining related studies and literature, we demonstrated that transition of studying abroad in Vietnam is not subjectively resulted by decision of the students themselves or of their families, but it is strongly influenced objectively by external determinants including cultural, social, political, foreign relation, economic, educational factors in the country. The results found five macro factors that influence the transition trends of Vietnamese international students over time, including number of students, study destinations, career after graduation and impact on society.
