Naotaka SHIRABE
(SOKEN,INC.)

I was appointed as the 12th President of ILASS-Japan for the term of year 2017 to 2018 at the Annual General Meeting held on December 19th in 2016 as a successor of the previous President, Prof. Masatoshi DAIKOKU. 26 council members, who were elected by ILASS-Japan members in the end of 2016, as well as the Vice-Presidents and I will manage the activities of ILASS-Japan..

During the past 20 years, ILASS-Japan, the Institute for Liquid Atomization and Spray Systems-Japan, has grown from a small group of university professors and industry researchers to become a widely recognized and respected professional society for the research and development of the liquid atomization and spray systems. I would like to express my deepest gratitude to the previous Presidents, Vice-Presidents, and all of the members for their continuous contributions to this remarkable achievement. In particular, I would like to deeply appreciate the previous ILASS-Japan Presidents listed below for their great efforts in the management of the Institute.

(Title omitted, Affiliations for the term period).

All of the previous Presidents belong to the academies but I am from the industry therefore I recognize myself to be expected to change innovatively the activities of the Institute.
The day I have started to be involved with the development of Electronic Fuel Injection System was the first day I have joined the company. At those days, I had lectures by Dr. Yasushi TANASAWA who was the president of Toyota Central R&D Labs., Inc.

Since at that time, I had been working on the atomization of electronic fuel injectors for passenger cars. Not like ultra-high speed cameras or optical measurement equipment of the droplet diameter available today, major methods to investigate the fuel spray was the flash synchronization photography which obtains only one image in one injection cycle, or the immersion liquid sampling method which requires enlarging droplet images trapped in the immersion liquid to measure the droplet diameter. As many of the researchers might have had, I also had a lot of difficulties with the sharpness of the droplet images or repeatability of the measurement. Those experiences drove me read a large number of proceedings of “The Conference on Liquid Atomization and Spray Systems in Japan”, which was the predecessor of The Atomization Symposium organized by this Institute, and that was my first encounter with this Institute. Those measurement technologies were primitive however I have convinced myself of the fundamental attitude toward the scientific research; simple questions through the careful observation with our own eyes should be the first step and much more important than the convenience, just pushing a start button.

My basic administration policy in this Institute will be six items listed below including continued topics from the previous year;

1) Increase of the membership
2) Enrichment of stipulations
3) Improvement in service quality for members
4) Consolidation of business-academia collaborations
5) Financial support to the academies
6) Collaboration with The International Institutes

1) Increase of the membership
The number of individual members has been decreasing during last few years, and in this year stood at around 240 individual members. We will implement appropriate measures to stop the decreases and to increase the membership again. Moreover, we would encourage companies to increase sustaining members. As in the bylaws, one of our missions is to advance scientific technologies, and the priority for it is to involve more university students and young engineers in this Institute, educate them through various chances as symposium, seminars, and conferences in order to enhance communication between members and other scientific organizations of liquid atomization.

2) Enrichment of stipulations
The stipulations of this institute have been prepared by the continuous effort of previous executives however further enrichment will be necessary for smooth operation of the Institute. We will prepare prioritized stipulations to the level of other large scientific institutes.

3) Improvement in service quality for members
We will improve service quality for members through reforming contents of ILASS-Japan symposium and the Atomization Seminar, the official journal "Biryuka", and the Committees belonging to Department of Research. The Atomization Symposium held on every December is the only conference in Japan dedicated to the liquid atomization technologies. This Symposium is essential in order to advance atomization technologies by exchanging informations and networking between researchers and engineers from various fields. The technical consult meeting in the night of the Symposium is also adequate for younger researchers including student members to exchange informations in a friendly manner. The Atomization Seminar is an event co-organized with the Japan Institute of Energy. About 40 engineers and students take the lectures on fundamental atomization theory, modeling of spray characteristics and design of injection systems for various applications, as well as the laboratory class in diagnostics for spray characterization. Students and younger engineers are encouraged to participate in the seminar. The ILASS-Japan official journal "Biryuka" publishes technical papers, review articles, attendees' reports of conferences, and events announcements. The journal is expected to be utilized as an information source of atomization technologies and research activities in combination with ILASS-International journal “Atomization and Sprays”. Submissions to the journal from members will be appreciated. The 3rd Committee belonging to Department of Research will operate as an opportunity to share informations of domestic and/or international conferences contributing to advance atomization technologies, latest and remarkable research results or technical information published. Your participation will be deeply appreciated.

4) Consolidation of business-academia collaborations
The 1st Committee belonging to Department of Research (The so-called Atomization Research Committee) is constituted with research members from academies registered in the committee and company members. From 2011, the research committee started organizing the exclusive meetings with the financial support of company members. The research members conduct research activities authorized in the committee. Progress or results of each activity are reported in the committee and active discussion is held among the members. Your participation to the committee will be really appreciated.

5) Financial support to the academies
Our Research support find Committee is accepting public application for research subjects based on its objective that ILASS-Japan conducts or supports research subjects contributing to the Institute and progress of atomization or granulation technologies, or even for seminal research subjects being led by young engineers, by supporting them financially. Related researchers will be encouraged to apply for the support.

6) Collaboration with The International Institutes
One of the important subjects for international exchange is to collaborate continuously with other ILASS organizations in Asia, which is ILASS-Korea, Taiwan, China, and India. Since Prof. Jiro SENDA established the Department of International Affairs in his duties as the President of ILASS-Japan, ILASS-Japan has been reinforcing framework to support for Prof. Masataka ARAI who was the President of ILASS-International at that time, and to collaborate with international committees. As reported in the previous general meeting, ILASS-India has joined ILASS-Asia and ILASS-Asia Conference was held in Chennai, India in 2016. In 2017, ILASS-Asia will be held in Jeju, Korea. ILASS-Japan will of course put maximum effort to support the Conference, however the key for the success is substantial number of submission and participation in the conference and therefore cooperation of the members will be highly appreciated. Furthermore, ILASS-Japan will provide information from each Regional ILASS to ILASS-Japan members by communicating closely with ILASS-Americas and ILASS-Europe. In 2018, ICLASS will be held at the University of Illinois, Chicago USA.

Finally, I will introduce our organization for 2017 to 2018. I believe our organization will be, slowly but steadily, rejuvenated and have more capability to implement a lot of beneficial activities for the members. We, the ILASS-Japan members, would like to work together with our colleagues in the international community to advance the science and technology of liquid atomization and spray systems.
