I am now studying about hypergraph colorings. Here hypergraph is a set together with a collection of its subsets. In detail, hypergraph coloring concerns with how to assign colors to elements of the set so that, in the same subset in the collection, it must have strictly more than 1 color. In particular, I will use topological properties of spaces associated to hypergraphs to find a number of colors which the hypergraph coloring cannot be taken. Thus, I have to acquire a knowledge of topology, which is a motivation for me to study in Department of Mathematices Sciences of this Faculty of Sciences. After acquiring a Ph.D. degree, I have to go back to work in Thailand because I must pay back my scholarship I had received until master degree. However, I will keep on researching and making use of this opportunity of studying in Japan to develop Thailand’s mathematics.
Background to Overseas Study
I got information on this faculty through one of my advisor, Associate Prof. Dai Tamaki. I found that the most detailed and easiest to understand source is my advisor’s homepage when I looked up a notion of a topological invariant. I thought that I may make good progress on topology if I am learned from him. And I got a chance. I was selected by Ministry of Education, Culture, Sports, Sciences and Technology (MEXT) to research and study in Doctoral course in Japan.

Research Topic & Plans for the Future
What I want to study is the field of elementary particles, since I’m always eager to know “the basis” of universe. And personally, I want to see and check those things out by experiments, although I also like to study theories too. If it is possible, I wish to take part in a big projects such as LHC or ILC experiments and want to make a contribution to the development of physics.
Background to Overseas Study
In my high school days, I was very interested in science, especially in the physics, since I had a belief this field will show and teach me every events occurring in the world. Also, I had a strong desire to study abroad, countries like Japan or America that has highly been developed in this field. Luckily, there was a program which Korea and Japan are executing cooperatively, and I was able to join the program. I think this is a very big chance to me to achieve my dream, "learn" and "understand" our universe.

Research Topic & Plans for the Future
After graduating from college I will return to Indonesia exactly to Papua and want to work as a researcher. In Papua are still a lot of rain forests that are rich in plants that are known efficacious cure various diseases, but unfortunately Papua's peoples still can't examine because of the shortage of human resources who really understands these things and can research these matters. Therefore, I want to return to Papua and help Papua's peoples to research the content of the plants that had still not reached because of various obstacles. Through this, I hope I can devote myself to Papua who have helped me in completing my education in Japan.
Background to Overseas Study
At the 2nd grade high school in 2004, I took the tests (mathematics and physics) held by Department of Education and Culture Papua in cooperation with Institute of Physics Development of Indonesia. This test was conducted to select students who would be prepared to participate on the inter-provincial science competition across Indonesia. Fortunately, I passed this test and to prepare myself for the competition I got the training for 7 months in Jakarta, the capital of Indonesia. After training and participated on the science competition which held August 2005 in Riau I returned to Papua to finished my education on high school. After graduating from high school as an advanced program for contestants of science competition, I and two friends other got an offer from Papua government in cooperation with Institute of Physics Development of Indonesia to continue my education in Japan. I was so happy to accept this offer because Japan is known as an advanced country in Asia which have good security, many beautiful places and of course delicious and healthy foods. In addition, from the little I also like watching Japanese anime and imagine if I was there someday. So when the offer came, I immediately said yes. Finally, after graduating high school in July of 2005, I went to Jakarta and studied Japanese language for 6 months there. After studying Japanese language for 6 months, in April of 2006 I went to Japan and lived in Tokyo for 1 year.
During my stay in Tokyo, I studied Japanese language at the Asian Students Cultural Association. In the last 6 months, in addition to Japanese language learning there I also studied physics, mathematics, chemistry and English to prepare myself for the entrance tests of University in Japan. In November of 2006, I took the test for foreigners who want to attend university in Japan. This test is known as Examination for Japanese University Admission for International Students (EJU). The test consists of Japanese language test (listening, auditory comprehension, reading, writing), mathematics, physics and chemistry. After the test, I started chose the university which I want to enter, and started collected application from these universities. After receiving the results of EJU in December, I re-select the universities in accordance with the test results that I got. After choosing 3 universities, in January, I sent some documents are necessary such as certificate of completion of high school etc to each university. Approximately 1 week after sending the documents, I got a letter from each university that written exam number. While doing those things, I began to prepare myself for college entrance tests with practiced interviews and learned chemistry. Then, in February of 2007, I took the entrance test in each university in the form of interviews and tests basic knowledge about chemistry. After receiving test results from each university which said that I passed the entrance tests of those universities, I discussed with my teacher in Japanese language school and then I decided to enter Shinshu University. After completing a variety of entry requirements, in March of 2007 I moved from Tokyo to Matsumoto and since April of 2007 I started my life as a student at Shinshu University and I really enjoyed it.

Research Topic & Plans for the Future
I am Amar Deep Regmi, a student from Nepal at Shinshu University. I completed my M. Sc. in geology from Tribhuvan University, Nepal, in 2008. From October 2009, I am at Shinshu University, Japan, as a Ph D research student. I would like to concentrate my research on landslide studies in Nepal.
As Nepal is a mountainous country, natural disasters such as landslides and flash floods are very common. Every year many people lose their lives and also a significant amount of property is damaged by these natural phenomena. In these circumstances, the study of such natural hazards is very important for the country as well as for the people living in these places. Thus, I have planned to study the landslides mainly occurring along the Mugling–Narayanghat road and also in some other parts of Nepal.
A landslide (or landslip) is a geological phenomenon which includes a wide range of ground movement (such as rock falls, deep slope failures and shallow debris flows), which can occur in almost all part of the earth and in all environments. However, their effect is more prominent in a mountainous area with steep slopes. Although the action of gravity is the primary driving force for a landslide to occur, there are other contributing factors affecting the original slope stability. Typically, pre-conditional factors build up specific sub-surface conditions that make the area or slope prone to failure, whereas the actual landslide often requires a trigger before being released. The main triggering factors of a landslide are rainfall, earthquake, groundwater, and also human activity on the slope.
The Mugling–Narayanghat road is the main highway connecting the capital of the country, Kathmandu, with rest of the country. It was severely affected by the landslides and debris flows triggered by the 1993 and 2003 intense and prolonged rainfalls respectively. After those two events, landslides have been very common in this road section. Especially, in the rainy season the road gets blocked for several days due to these natural phenomena.
During my research, I would like to investigate the main inherent factors of these instabilities and also would like to propose some remedial measures to control them. In fact, such landslides are present on almost all the roads that are built on the fragile mountainous terrain. I would like to know the main types of landslide that occur within the different rock types found in Nepal. The investigation will eventually help to: 1) classify the main landslide types occurring within the country, 2) to propose some cost-effective control measures that can help to cope with these and similar other disasters in the future, and 3) to develop long-term strategies for their prediction, mitigation and control.
Background to Overseas Study
Since Japan is a mountainous country like Nepal, it is also severely affected by landslides. However, here the study of landslides and other natural disasters has been done extensively. The geologist and engineer working in the field of landslide have great experience and knowledge in this field.
In Nepal, studies and researches in these types of natural disaster have been initiated just recently. Though a lot of studies are being carried out at present regarding the slope stability analysis, proper mitigative measures have not been developed so far.
As in-depth study of these phenomena needs many types of laboratory equipment, and in Nepal such facilities are almost unavailable, it is not possible to carry out a detailed laboratory research in my country alone. On the other hand, geochemical analysis of rock and soil is one of the effective methods of landslide investigation. However, no one has initiated such investigation in Nepal. Therefore, I have planned to do such studies at Shinshu University, as my Professor, Dr. Koki Yoshida, has already successfully applied such techniques to analyse many landslides in Japan.
Thus, I hope that my further research and investigation at a well equipped institution like Shinshu University can unravel the geological causes of such large landslides. Also, Shinshu University is surrounded by mountains from almost all sides and landslides are very common there. Consequently, it is possible for me to go to see such landslides in the field and to learn the applied mitigation measures, which can be very helpful for developing appropriate landslide control techniques for Nepal. All these aspects encouraged me to come to Shinshu University for further studies and research in the field of landslide investigation.

Research title: Phylogeography of introgression between sibling species of land snails. I am proud of conducting a research project of pure science, which is irrelevant of practical applications for industry, technology or medicine. The goal of my project is to resolve the mystery of one-way introgression detected by using mitochondrial DNA against what breeding experiments predict. I was fisrt afraid of investigating the cause of a fact that cannot be explained by common sense or established ideas in textbooks. However, I have been enjoying excitements of solving a question that has not ever been tackled by others. I wish to have an occupation by which I can keep sharing this type of pleasure of driving pure science.
Background to Overseas Study
My ex-supervisor, Prof. Somsak Panha at Chulalongkorn University, where I was majoring in biology, recommended me to work with Prof. Takahiro Asami because of Prof. Asami's innnovative research and internationally recognized achievements in evolutionary biology. The MEXT scholarship for Kokuhi-ryugaku made my dream true. I thank all people that made this precious opportunity to study and work with him possible.

Several species of commonly occurring cyanobacteria such as Microcystis, Anabaena and Oscillatoria produce toxic microcystin. Microcystin impose a health risk to animals and human populations. Therefore, I am studying about the cyanobacteria removal and the dynamic of cyanotoxin by the chemical coagulation. So far, there are reported that the chemical coagulant was not cause the cell damage of a cyanobacteria. But, according to my results, the chemical coagulation was caused cell damage, and a large quantity of cyanotoxin was released. So, my research is very interestingly in progress. I am detailedly planning to study about the dynamic of cyanotoxin after the chemical coagulation.
Background to Overseas Study
The Shinshu University knew as the place where seniors studied abroad. There was the request that it wants to study the doctor's course in the foreign country. The opportunity of Japanese government scholarship was found and I came for studying to Japan.
