水環境国際招聘賞（いであ招聘賞）（JSWE-IDEA Water Environment InternationalExchange Award）授賞に関して
本会では，水環境分野の国際交流・国際協力の促進を目的として，いであ株式会社からのご出捐により，水環境国際招聘賞と水環境国際活動賞を設けております。
水環境国際招聘賞は本会年会で研究発表を行う海外在住外国人会員に対して，来日費用等の助成を行う制度です。第 48 回年会には韓国と中国から各１名を招聘し，研究発表を行っていただきました。
発表を終えて帰国された受賞者に参加報告を書いていただきましたので，ご紹介します。
なお，今年度の水環境国際招聘賞の募集案内は夏頃に本誌会告に掲載する予定です。

IT-BT-ET based Technologies for Water Management

Kim Hyunook（金First and foremost, I would like to thank to theJapan Society on Water Environment (JSWE) for
the JSWE-IDEA Water Environment International
Exchange Award that has been awarded to me in
the 48 th Annual Conference of JSWE held at Tohoku
University from 17 th to 19 th of March, 2014. I havebeen participating in JSWE Annual Conference foralmost 10 years through JSWE special invitation toKorean Society of Environment Engineers (KSEE).
In my presentation, we have developed a new pHbased approach to eﬀectively determine the end pointof breakpoint chlorination titration for water samples
even with a low ammonia concentration. Based on thisapproach, we have suggested an automatic control
strategy for the chlorination process in the water orwastewater treatment plants.
One of the presentations made by my students atthe conference was regarding our newly developed
compact water quality analyzer system. In thepresentation, she demonstrated the superiority of
our system by comparing its performance withconventional water quality analyzer systems. The
software sensor technology to predict the TN and TP
concentrations has been implemented in our newly
developed system and it is able to predict them within
5 min. This technology not only succeeds to shorten
the analysis time signiﬁcantly but signiﬁcantly reduces,
if not eliminates, the use of chemicals or reagent. Our
analyzer also has been applied to control a sequencing206鉉旭）batch reactor (SBR) along with a process model. Basedon the data from the on-line water quality analyzers
installed before, inside, and after the SBR, the processmodel determines optimal duration of each operational
phase of the reactor. NH 4 +, NO 3 ‑, and PO 4 3‑ werecontinuously monitored to automatically calibrate themodel and to better control the SBR.
The last study presented at the conference wasregarding a smartphone application for the public
to report any pollution event happening in a stream.
In this study, we emphasized the role of public thatreport any pollution event occurring in a stream.
To sum up all of my research work, I believe
the effectiveness of IT-BT-ET based technology inmanaging water related issues. Integration of various
diﬀerent technologies is crucial. I consider the award
that I received as a proof of the mutual effort andrelationship between Korea and Japan in the ﬁeld ofwater research. Therefore, I greatly hope that moreyoung researchers from Asia (especially developedcountries) participate this WATER conference andcollaborate with us.
Once again I would like to express my hearty
appreciation to the JSWE members, conference
committees and fellow researchers for nominating andchoosing me as the recipient of this prestigious award
at the 48 th Annual Conference of JSWE. I am looking
forward to attend the JSWE conference or event again
in the future.
