Upgraded Cooperation between Korea and Japan byOverseas Member Invitation Program of JSWE
Vice President, Korea Society of Environmental EngineersProfessor, Chungbuk National University
大韓環境工學會 副會長，
（忠北大學校 敎授，）河On basis of the recommendation by Korean societyof environmental engineers（KSEE）and the overseas
member invitation program by Japan society on waterand environment（JSWE）, I took an opportunity tothparticipate in the 47 annual conference of JSWE heldat Osaka Institute of Technology from 11 th to 13 thof March, 2013. I gave a lecture on the innovation ofwater quality management by coupling urban planningwith Low Impact Development（LID）scheme inKorea. I would like to express my sincere thankfulness
to everyone that it truly is an honor to win the JSWE‑IDEA Water Environment International ExchangeAward.
Throughout the lecture, I summarized Korea s
national experience in improving the water qualityof public water body. For last three decades,
our continuous effort in this field has achieved aremarkable result in realizing 90％ of national sewage
coverage ratio. Moreover, public concerns shifted to
the water quality conservation of public water body‑such as the natural river and other water resources‑from the quality standard mandated at the end of pipe.
Based on the Korean Total Maximum Daily Loads（KTMDL）Act, province governments and localmunicipalities in the watersheds of three major riversof Korea‑Nakdong, Keum and Youngsan‑developed thetotal load management plan related to water qualitypollution. It turned out to be an impactful plan thatmeets the water quality standard and TMDL pollution
load mandated by the Ministry of Environment. The
eﬀectiveness of KTMDL was clearly demonstrated by194

improving over 88％ of water quality.
However, despite the good achievement of public
water quality management policies, diffuse pollution（non‑point sources）issues have been left behind
the governmental regulation of KTMDL as anunresolved problem. Regarding the issue of diffuse
pollution, we should design and implement a numberof interdisciplinary approaches in order to control
water quality. One of the most important sources ofdiffuse pollution is a land development materializedby establishing an urban/nation planning. BestManagement Practices（BMPs）have been applied to
manage diﬀuse pollution in the ﬁeld of water quality
schemes, and are expected to provide eﬀective roles ina low impact development（LID）application to landdevelopment projects. In my lecture, a quantitativescheme to couple urban planning with LID wasintroduced including examples of its implementation in
new town projects in Korea.
About 30 years ago, I was an international student
enrolled in the doctoral course of Osaka University
and advisee of Professor Sueishi Tomotaro in thedepartment of environmental engineering. My
professional dream in the water environmental field
was well‑honed by committed support of my adviser
and unique characteristic of Japanese academic
environment and culture. The Journal of JSWE
deﬁnitely gave me an opportunity to broaden the rangeof my knowledge upon water and environmental ﬁelds.
My winning of this award has a signiﬁcant meaning
to many of us‑with no doubt, we have made a step

closer to a long lasting friendship of two societies,
Korea and Japan. Once again, I would like to share
this joy and appreciation with all of members of JSWE
for their cooperation and initiation to upgrade therelationship between Japan and Korea. I believe thatthe cooperation between KSEE and JSWE will besustainable and upgradable through mutual eﬀorts infuture.

Great Help to a Young Researcher from JSWE
Graduate School at Shenzhen, Tsinghua University
清华大学深圳研究生院呉When I was a Ph.D. candidate, I hoped to attend
the Annual Conference of Japan Society on Water
Environment because that the conference is very
important and famous in the field of environment
protection. After 7 years, I have the honor to obtain
the JSWE‑IDEA Water Environment International
E x c h a n g e A w a r d a n d a t t e n d t h e 4 7 th A n n u a l
Conference of JSWE with the recommendation ofChinese Society of Environmental Science（CSES）and
support from overseas member invitation program ofJSWE. I am grateful for the great help from JSWE andCSES.
JSWE have done lots of work on promoting
cooperation between Chinese and Japaneseresearchers. In China, I have attended China‑Japan
Symposium on Water Environment held by CSES
and JSWE several times and thusly make friends
with many Japanese researchers. I get much useful
information and improve my research from JSWE andJapanese friends. Therefore, I become an overseas
member of JSWE after I finished my postdoctoral
work and got a faculty position. I read the every issueof JSWE s journal and ﬁnd lots of helpful information
which improve my research.
My research ﬁeld is technologies to assess and guard
reclaimed water safety. Reclaimed water is an attractive
method to solve the water shortage problem. However,there are many types of toxic and harmful pollutants in
untreated wastewater. It is needed to control the risks
induced by pollutants during wastewater reclamation.
Therefore, I optimize chemical technologies（ozonationand chlorination etc.）to control dissolved organic
matter and its potential risks in reclaimed water
including endocrine disruption eﬀect, genotoxicity, anddisinfection by‑products formation.
I introduced the work concerning toxicity removal
during wastewater reclamation processes in the 47 th
annual conference. Wastewater before treatment
contains many types of genotoxic chemicals including
polycyclic aromatic hydrocarbons. Furthermore,reclaimed water treatment such as chlorine
disinfection can also form some genotoxic pollutants

including trihalomethanes, haloacetic acids, and‑nitrosodimethylamine. Since the toxic chemicals arevery complex, only measuring and controlling sometypical chemicals are not suﬃcient for reducing the riskof reclaimed water. It is needed to evaluate and remove
genotoxicity of wastewater eﬄuent. In the presentation,
the genotoxicity in the wastewater secondary eﬄuent
samples and the key fractions associated withgenotoxicity in the samples were introduced. And thechanges of genotoxicity and typical fractions during
wastewater reclamation processes, especially chlorine
disinfection were also investigated.
It is my third time to visit Japan and I keep very
good friendships with many Japanese researchers
from Kyoto, Yokohama, Osaka, and Tsukuba. During
the 47 th annual conference, I not only introduced mywork but also attended many interesting presentations
given by Japanese researchers and meet lots of goodfriends who are the experts in the ﬁelds of toxicology,environmental chemistry, and environmentalengineering. During the 3 days, we exchanged theinformation and new ideas about our research andlook forward to further cooperation in the future. It
should be noted that the exhibition of water treatment
equipments, materials and reagents is very interesting.
Many novel products including membrane, andcatalyzer made a deep impression on me. From theexhibition, I found some interesting products and hopeto use them in my study in the future. I believed thatthe cooperation between researchers and companies
on technologies and equipments development plays animportant role in water quality improvement.
How time ﬂies! The time of 47 th annual conferenceof JSWE was very short. When I listened to the ﬁnal
presentation, I found that it is time to say goodbye.
After the conference, I will go on the discussion andcooperation with Japanese friends. I believe that young
researchers friendships will promote the cooperation
between China and Japan in water environment ﬁeld.
I really appreciate the great help from JSWE. I lookforward to attending the annual conference of JSWE
in the future!
