2013/10/30-11/7: Academic seminors in Qingdao, Jinan, and Xi'an for JSPS-NSFC Bilatelal Research

Our group is working for a bilatelal research program entitled "Aging and Optical Properties of Widespread Soot Particles in East Asia" thanks to the fund by JSPS in Japan and NSFC in China. On this occasion, our group (Prof. Zhang and graduate students), Prof. Kojia and her graduate student, and Prof. Hayasaka and Dr. Katagiri from Tohoku University visited Ocean University of China (Qingdao), Shandong University (Jinan), the Institute of Earth Environment, Chinese Academiy of Sciences（Xi'an). This stay was a very good opportunity for graduate students to make friendship with Chinese students.

2013/10/16: Professor Chak K. CHAN lectured us how to write good research papers
Professor Chan is a chief editer of Atmospheric Environment that is very famous journal in the field of atmospheric science. His leture was entitled "How to Get Pubulished in a Research Journal". He told us how to prepare a paper to submit manuscript to research journals as following three points.
1. What steps do I need to take before write my paper?
2. How can I ensure I am using proper manuscript language?
3. How do I build up my article properly?
Since the talk was corroborated by his experience as a chief editor of an international journal, graduate students and young research fellows could learn the good way to improve the quality of their papers for international journals.

After the lecture, graduate students as listed below introduced their research and discussed with Prof. Chan.
Kotaro Murata "Transport of Bacterial Cells Toward the Northwest Pacific in Northern Hemisphere Westerly Winds"
Satoshi Fukushima "Comparison of Airborne Particles and Deposition Particles Associated with Asian Dust at Kyushu Western Coast"
Yuki Tsugehata "Concentration of Airborne Particles in Asian Dust Plumes: Comparison of Cases in Qingdao and Amakusa in Spring 2010"
Ryutaro Matsuoka "Evolution of Aerosol Particles in the Boundary Layer in Amakusa"

-----This project was funded by the grant from the president of Prefectrual University of Kumamoto.
