The difficult past was a catastrophic event that led to “mass death,” and the damage was felt not only by the dead but also by the survivors. This applies to wars, pollution damage, isolation policies for Hansen’s disease, pollution damage, etc. Furthermore, because such damage involves a complex relationship between perpetrators and victims, the “interpretation = meaning” of the event is likely to be divided depending on one’s position, making it difficult to pass on experiences. Based on the concepts of collaboration and ESD, I create spaces for dialogue, practice public history, and deepen my research on the inheritance of difficult past experiences.

【Study on students who can not adapt to Active Learning (AL)】
There are students who can not adapt to AL, such as students who avoid AL courses or remain silent during group activities. Therefore, I have been working on research focusing on the formation of an environment that facilitates collaboration between such students and other students, learning and supporting each other. I have also been conducting research on organizational support methods for such students.

【Research on Hope】
I have been doing research from the viewpoint of career education about a method of human resource training that enables students to find hope, keep it, and move forward under any difficult circumstances.

【Performance appraisal of nature experience and physical activity】
Although it is empirically known that nature experiences and physical activities nurture resilience, there are a few systematic studies on this. Therefore, in order to know the situation and the background of students. I have conducted performance appraisal.

The Cohen-Macaulay modules have been studied as important objects linking algebraic geometry and the module theory of algebras.
The Cohen-Macaulay modules are also a natural higher generalization of finitely generated modules over finite dimensional algebras.
I am interested in the module theory aspect of the Cohen-Macaulay module.
I am currently studying the representation type of the Cohen-Macaulay modules from its geometric structure via the functor category.

My research interests are in the origin and evolution of life on Earth in the 4.6 billion-years geological records; particularly the evolution of eukaryotes and multicellular animals. I am trying to clarify the environmental changes across these evolutions, based on the geological fieldworks in UK, China, Gabon, Mongolia, etc., the stratigraphic reconstructions (lithogy, fossils, age determination), and the paleoenvironmental reconstructions (chemical analyes). I am also developing teaching materials for geoscience education using VR technology.

I am interested in a quantum spin system where nontrivial magnetic ground states appear. To investigate those experimentally, vaious methods are utilized from static and dyanmic points of view.
By reducing the system saize some materials is weakening , and another is strengthening in magnetic properties. To learn more about the origins of those, I am conducting magnetic measurements with high sensitivity.
Experimetnal studies on hydrogen-induced phenomena are also one of my essential research activities. Also, I am carrying out the development of a new method to evaluate hydrogen absorption properties aiming at high-performance hydrogen strage.

In the future society, collaboration between leaders and followers is important.
Therefore, it is important that leaders also learn about followers and learn about followership.
The human resources that companies look for in new hires will include an element of followership.
Mastery of leadership requires that you make your own changes in your own behavior.
It is necessary to look back at one’s own behavior, notice unconscious comments and actions, and change oneself.
We are currently conducting research on building relationships with others, developing oneself, and becoming self-reliant through leadership education.

I have wide experience in teaching English in several types of schools such as junior high and high schools, including a correspondence course high school, and a university. So, in the field of English Language Education, I am interested in how to improve English language skills of EFL learners at each stage of language learning and lead them to be self-disciplined learners from the viewpoint of SLA.
In one case, learners at the higher education, e.g. university students, are required to read several literatures in order to gather information or knowledge on their interest. Some literatures may be written in Japanese, but in most cases, they are written in other languages, including English. I am investigating some possible aspects related to their effective reading, such as formal instruction, vocabulary building, background knowledge etc., and would like to identify aspects effective to reading for information gathering. These aspects may vary according to learner characteristics. In another case, I am performing studies of effective use of media such as music and movie in the language classroom.
Moreover, I would like to investigate the potentiality of BASIC English, which was “discovered” by Charles Kay Ogden, and develop educational materials for EFL/ESL Learners based on Ogden’s idea shown in BASIC English. BASIC English is a simplified and organized English brought up by Charles Kay Ogden as an international auxiliary language, and as an aid for teaching English as a second language. I think his idea is still very significant even today.

I specialize in representation of commutative algebras. Commutative algebras were initiated to give us the basic frameworks of algebraic geometry, invariant theory and number theory. Afterwards, it gained its own problem awareness and has become one of the research fields of mathematics. Nowadays, it has closed ties to various fields and has actively been researched.
As one of the research purposes, representation theory of commutative algebras aims at understanding the structure of the category of modules over a commutative ring and the derived category and e.t.c..
Now I am interested in representation theory of commutative dg algebras and will study it.

The establishment of physique (body type) and physical fitness assessment methods that consider individual growth and development is an important issue in school health. In particular, for late adolescents (high school students), who are in the final stages of their physical growth, it is important from the perspective of future health to acquire physical fitness appropriate to their physique. However, conventional physical fitness assessment often overestimates (or underestimates) physical fitness. Hence, it is necessary to develop a new evaluation method that takes individual physique into account and can be practically implemented in educational settings. In our research, we have proposed a new physique assessment (body composition category model) based on the combination of fat mass and lean body mass. In the future, we will examine the validity of this model and the evaluation of physical fitness and athletic ability by body size, verify the validity of the evaluation table, and consider applying it to the educational field.

At first, I had an keen interest in self-reflection that goes with self-narrative　(autobiography, diary and self-portray etc.), especially in its influence on personality development. To pursue this issue, I tackled researches on psychoanalysis, German expressionism and phanomenology. I also engaged in artisitic activities and created works as well.

For these years, I have been researching on philosophy of Wilhelm Dilthey, a German philosopher in 19th century, who aimed to establish humanities and social sciences as rigorous “moral science”. Recently I begin to make a study of religion and aesthetics through his works, which requires an interdisciplinary study that shows humanities and social sciences as a whole.

In the future, I hope to comprehend herumeneutics from 18th century until 20th century, which is still not clarified in Japan. Hermeneutics itself is difficult to define; it started as traditional hermeneutics in the thought of Herder, Droysen, Dilthey etc, and developed into new hermeneutics of Heidegger and Gadamar in 20th century, making idea of hermeneutics a confused one. It also had great influence on German Idealism, New Kantianism, philosophy of Nietzsche, Ricoeur, and Derrida, and psychoanalysis, which means that interdisciplinary study is necessary and essential. I can strongly feel the importance of joint study these days.

I am studying the images and movements of the learners in dance, and the teaching methods that elicited physical expression.
I am studying the image and movement in dance, such as what kind of image the learner perceives and what kind of movement appears,toward the realization of creative physical expression.
I would like to develop learning and teaching methods through exercise and sports, including dance.
