INSTITUTE FOR ADVANCED RESEARCHFor Further progress of the Institute

LETTERThe Institute for Advanced Research (IAR) of Nagoya University was established in 2002
to promote academic studies, and is independent of the schools and departments at the
University, as stipulated in the University Academic Charter. The fundamental objective of thisinstitute is to foster and produce academic achievements at a prominent and internationallysignificant level. Such achievements are indispensable for the University not only to be widely
recognized as a seat of learning but also to cultivate “courageous intellectuals.” All members of the
University should strive for an unsurpassed level of creative academic research. IAR has been andwill be a center for assembling and coordinating various fields of state-of-the-art academic
research in Nagoya University.
Internationally, IAR is a member of the Steering Committee of the University-Based Institutes
for Advanced Study (UBIAS) and has some leading international exchange activities in researchand education. In this context, we are planning to host a Nagoya University IAR international
workshop on university education, where more than ten Institutes for Advanced Study (IASs) and
IARs from various parts of the world including several IAS/IARs from European universities
together with several IAS/IAR from Southeast Asian Universities in November this year. In thisworkshop, “The East and West” IAS/IAR will get together here in Nagoya for the first time to
discuss a common theme in university education related to IAS/IAR and to strengthen mutual ties.
I sincerely hope that all participants in the workshop at the Nagoya University IAR will enjoy
discussing such a cross-disciplinary theme and exchanging ideas of mutual interest in the forum.

During the past seven years, the IAR has also been coordinating an important University
program, the so-called Young Leaders Cultivation (YLC) Tenure-track Program, which has playeda crucial role in cultivating and supporting talented young researchers in various fields. The
program has contributed greatly to converting the outcomes of excellent studies done by IAR
researchers in individual departments into common property of all members of the University.
This year, we have newly hired eight brilliant young researchers in various fields as YLC Designated
Assistant Professors. Readers may find this issue’ s Special Interview and Research Highlights
interesting, and the interview is with Professor Tsuneko Okazaki, professor emeritus at Nagoya
University, who was honored as a Person of Cultural Merit in 2015 and known for the discovery of“Okazaki Fragments” with her late husband, Professor Reiji Okazaki.

We knew that DNA polymerase cannot start synthesis of DNA
de novo but needs already existing, so-called primer termini, to start
synthesis. We analyzed the primer termini used for the synthesis tosee how the synthesis of these short fragments was started
repeatedly. As the result, we found that these primers were short
RNA primers. The RNA was broken down and the gaps thus
produced were filled up with DNA and short DNA chains werebound together with an enzyme named ligase. It was proved thatshort fragments were accumulated with involvement of various
reactions of the enzymes and the suppression of the enzymes. This
finally clarified the discontinuous replication.

totally absorbed in the research in those days.
Besides research, Reiji was very fond of sumo wrestling, andbecause we had no TV set, we used to go to an udon noodle shopwhere a TV set was installed to watch sumo broadcasts. There wereno other entertainments actually.

̶̶ What motivated you to be interested in naturalscience?

Tsuneko
OKAZAKI
Dr. Tsuneko Okazaki is a molecular biologist renowned for her discovery of the Okazaki fragments with her husband Dr. Reiji
Okazaki. Even after the early death of Dr. Reiji Okazaki in 1975, she continued their research and clarified the mechanisms of
discontinuous DNA replication. She graduated from Nagoya University in 1956 and received a PhD in Science from the same
university in 1963. She was awarded a Fulbright travel grant and studied in the USA from 1960 to 1963; she studied as a fellow in
1960-1961 at Washington University, School of Pharmacology (supervised by Dr. Jack L. Strominger) and from 1961-1963 at
Stanford University, School of Medicine (supervised by Dr. Arthur Kornberg). She worked at the Graduate School of Science at
Nagoya University as an assistant- (1965-1976), associate- (1976-1983) and full professor (1983-1997). She was also a full professor(1997-2002) and a visiting professor (2002-2008) of the Institute for Comprehensive Medical Science at Fujita Health University,and served as a director of the Japan Society for Promotion of Science, Stockholm Office (2004-2007) and president and CEO of
Chromo Research Inc. (2008-2014). In 2016, she became a University Professor at Nagoya University and a member of the IAR
Academy. She has won numerous awards such as the L'Oréal-UNESCO Awards for Women in Science (2000), the Medal with Purple
Ribbon (2000), the Order of the Sacred Treasure, Gold Rays withNeck Ribbon (2008) and the Person of Cultural Merit (2015).

My Life & Okazaki Fragments
̶̶ Could you please explain what Okazaki
fragments are?
OKAZAKI: DNA has a double helix structure. In replication ofDNA, the double strands of the DNA helix are unwound to
produce a new strand complementar y to each strand.
Conventionally, it was believed that there were two different
enzymes, one elongating the strand from the 5' to 3' direction andanother elongating the strand from the 3' to 5' direction. However,in fact, there was only one enzyme that elongates the strand from the
5' to 3' direction. So we attempted to explain how two strands wereoriented in the double helix with only one enzyme. This is referred
to as discontinuous replication.
We formulated a hypothesis that the reverse strand running in
the opposite direction is synthesized in a series of short DNA

03 | IAR LETTER | March 2017

fragments. What we did was to clarify the mechanism of how thesynthesis of the strand proceeds involving various reactions such as
binding the short DNA fragments together. Okazaki fragments arethose short strands of DNA that are discontinuously synthesized in
the reserve direction.
When we first started this research, we knew nothing at allabout the strands, including their length. We took the strategy oflabeling of the end of the fragments being elongated with shortintervals and monitoring the shift of the labeled ends to see on
which side they would be found. At first, the labels were found in the
short fragments in a concentrated manner; however, the labels
shifted to the longer fragments after being left for a while. We
therefore assumed that the fragments were formed in a discontinuous
manner although we had to take various steps before the assumption
was proved.

OKAZAKI: I was born in Moriyama ward of Nagoya city. I grew up
during the war. My father was a doctor; he lost his hospital in thewar, and worked as a director of a hospital in Gamagori city. I was a
junior high school student then and used to visit there, where I spent
my summer holidays swimming in the sea or looking into a
microscope. My father showed me the process of bacterial cells dying
due to penicillin used for treatment. I naturally became interested inorganisms and bioscience.

̶̶ What was the research environment like?

̶̶ What was your reason for choosing biology inuniversity?

̶̶ Then the two of you went to America…

OKAZAKI: My father planned to make all his children medical
doctors. So by not choosing to enter the medical department I was an
unworthy daughter.
Doctors need to be very sociable. They need to work with a lotof staff, and most of all, doctors should interact effectively with many
patients. Because I was not a very sociable person, I thought I was notsuited to being a doctor. So, instead of entering the medical
department, I chose biolog y, since that was what I was mostinterested in.

OKAZAKI: Japan was still very poor in those days, and the research
environment was incomparably poorer than it is today. The
laboratory was a wooden building and there was a leak in the roofcaused by the Ise Bay Typhoon, which damaged all our laboratory
samples. We were short of research funds so we often bought reagentswith money from our own pockets.

OKAZAKI: In 1960, Reiji and I went to the U.S. by ship, on the
Hikawa Maru, and studied in Washington University and Stanford
University as recipients of the Fulbright travel expense scholarship.
In Stanford University, we studied DNA polymerase in thelaboratory of Professor Arthur Kornberg who won the Nobel Prize.
In 1963, Reiji was called back by Nagoya University and wereturned to Japan. Reiji became an assistant professor while I
returned to the doctoral course and obtained a Ph.D. After that, I
became an assistant in Reiji’s laboratory and started to work on the
research with him.

̶̶ In those days, there were only a few female
researchers. How did you dare to become a female
researcher?
OKAZAKI: At the time, female students in the department of
biology where I was studying had difficulties finding a job. Other
than being a researcher, teaching at a high school was the only choiceof employment open to us. Today it is an era of bioscience andwomen are in gainful employment. But the situation was completely
different then.

̶̶ You met your husband, Dr. Reiji Okazaki, when
you were a university student.
OKAZAKI: When I was in my senior year of university, I met Reiji
who was working as a researcher then. We got married in the springin which I advanced to the graduate school. We started our joint
research in the same laboratory. Reiji was the type of scientist who
thought of nothing else but his research, and as I recall we were

OKAZAKI FRAGMENTS
Okazaki fragments are short DNA fragments that are temporarily produced during DNA
replication at the lagging-strand. DNA replication is started by separating the double helix
by DNA helicase. Two complementary single-stranded DNA are formed, which will
become templates for DNA synthesis. One of the single DNA strands is replicatedcontinuously (leading-strand), but this is not possible for the other strand (lagging-strand).
It is because DNA polymerase, the enzyme synthesizing new DNA, extends DNA strands in
one direction only (from 5’ to 3’). In the process of lagging-chain production, whose overall
direction of elongation is from 3’ to 5’ Okazaki fragments are produced first in the direction
opposite to that of fork progression and are later connected to form a complete long strand.

Special Interview | Tsuneko OK A ZA K I

̶̶ Were working conditions for women in the U.S.
very different from those in Japan in those days?
OKAZAKI : A woman was not recognized as a full-fledged
researcher in Japan back then. A woman researcher was not evengiven a post. That was the atmosphere of the time. Contrarily, in theStates, I was recognized as full-fledged researcher. I appreciated thatvery much.
In Japan, it was the matter of course that women stayed at homeraising their children. After I came back to Japan, I had my firstchild at the age of 30, and my second child at the age of 40. Unlike
today, there was no framework for parenting support, such as
nurseries to look after children. I had to make these arrangementson my own. I even took part in a citizen’s campaign demanding
improvement of nurseries.

̶̶ How did you balance your research activities
and child-raising?
OKAZAKI: It was very hard. I sent my children to a nursery but
they came home at 3:00 or 4:00 in the afternoon. After that time, I
hired a part-time baby-sitter to look after them. But even thisarrangement was limited to 5:00 at the latest. Then, I had to go andpick them up, so I took them to the laboratory, put them in a big
cardboard box and made them play there.
It was even harder after they went to elementary school,
because they came home earlier.
A person who used to work at my father’s hospital lived in myneighborhood and she looked after my children after school. I owe
her a great deal.
W i t h r e s p e c t t o r e s e a r c h , w e s t a r t e d w o r ki n g o n“discontinuous replication” from around 1964. We discovered the
Okazaki fragments and published our results in 1967.

̶̶ Your husband passed away in 1975.

̶̶ About student scholarship

OKAZAKI: He was in Hiroshima in the year World War II ended.
About two years prior to his death, he showed bleeding on his skin
and we knew that he suffered from leukemia. No treatment wasavailable for leukemia back then. In 1975, he was called to an academic
meeting in Canada, and died shortly after returning to Japan.
His death meant that the laboratory lost its boss and ourchildren lost their father. People suggested that I should give up theresearch because of the children. At such time, my respected
professor Kornberg in America sent me a letter, saying “never giveup the research; the world is waiting for the outcome of yourresearch at Nagoya.” This letter encouraged me very much. My son
was in the 6th grade of elementary school and my daughter was two
and a half years old then. I asked the neighbor who had been
baby-sitting my children to continue to look after them. I really owe
her so much.

OKAZAKI: Once I personally provided financial aid for a graduate
student who could not get a scholarship. The current Japanesescholarship program is provided mainly in the form of student loansthat force students to accumulate large amounts of debt when they
graduate. Scholarships that do not need to be paid back should beawarded to competent young students. This is extremely importantin terms of cultivation of human resources, and this style ofscholarship is provided in many countries.

̶̶ What sort of research did you do after yourhusband’s death?
OKAZAKI: I continued the research that I had been doing with
Reiji. I had competent joint researchers. The biggest mystery was theprimer RNA - how is it that short fragments are formed repeatedly?
So we worked on isolating the primer and determining its structure.

̶̶ What is the significance of the research on
Okazaki fragments and discontinuous replication?
OKAZAKI: We discovered the truth - the concept of a primer,
the role of the short sequence of bases to trigger DNA replication.
Using this, methods such as PCR, to design a base sequence of a
specific region as a primer and amplify gaps, are widely used now.

̶̶ How do you think university students andgraduate school students should prepare when aiming
to be a researcher? What is your advice for them?
̶̶ Who had the most influence on you?
OKA Z AK I : There were many people who helped me andencouraged me. When Reiji passed away, I might have quit the
research if it had not been for Professor Kornberg ’s letter
encouraging me to continue with it. I also received encouragementfrom researchers all over the world.

̶̶ Do you have any advice to younger women
researchers or other working women about thebalance between career and home?
OKAZAKI: I think there must be very hard times, but the mostimportant thing is not to quit in any case. Difficult times or toughtimes are limited to a short while. Once you have gone through suchtimes, children grow up. In the case of a researcher, if you quit, yourpost is likely to be filled by someone else, making it difficult for you
to return to it. Today, supportive measures are taken by universities.
Making use of these advantages, it is important to manage to getthrough hard times by taking holidays or decreasing working hours.

OKAZAKI: An important thing is that the starting point of a
research project is to have a question asked initially by the researcher
himself/herself, who then attempts to clarify it. It is not somethingthat you can be told by someone else to do.
First, the researcher should think about what he/she wants toseek, and discuss it thoroughly. Some people avoid discussion tokeep some matters secret, but it is important to engage in a lot of
discussion with people around you.

̶̶ What is the mechanism of living organisms or
mysteries of nature for you?
OKAZAKI: The mechanism of nature is extremely ingenious,
always exceeding what I have imagined. There are so many things we
do not know yet. When we were doing the early research, we simply
studied the naked DNA, while now researchers are studying achromosome as a packaged structure containing composite
information to see how things are inherited. What researchers are
studying now is much more advanced.

̶̶ What do you think is important now, to give
more opportunities for women?
OKAZAKI: I think it is desirable that a system should be available
for women to return to work after leaving temporarily or todecrease their working hours for child-birth and child rearing. The
support of nurseries is also important.
On top of that, another important factor is whether thefamily and surrounding people understand the situation and arewilling to provide support. Criticism from parents or sisters orbrothers is often very harsh. Many people together could change
the public mind-set that says “keeping house and raising children
is women’s work.”
My daughter lives in Sweden now. Men in Sweden know how
to raise a child and do housework. They are good cooks too. The
social environment is such that it is a common practice for men to
do all kinds of housework and child-rearing, as much as women do,
and boys are brought up in that way. So in Japan too, it is importantto prepare boys to be able to do household chores and raise children
as a matter of course.

matter due to their physical properties, which depends on their energy; forinstance, high energy muons are able to penetrate more than 1 km thicklimestones. Through this property, if a hidden space inside a pyramid ispresent and muons pass through the space, then more muons are able topenetrate the pyramid than without the space. To take transmission images,
directional sensitive detectors are needed because Cosmic ray muons arehitting the ground from every direction. Directional distribution of Cosmic
ray muons measured by a detector shows an absorption effect while passing
through matter and this can be converted into the density length, which isdefined as the product of density and length along the pass, in each direction
from the detector. Thus, the inner structure of a pyramid can bereconstructed.

Nuclear Emulsion
A nuclear emulsion is a photographic film used for detecting
three-dimensional trajectories of radiation with sub-micrometric spatial
resolution thanks to very small silver bromide crystals, which work as asensor of radiation [1, 2, 3]. It is thin, lightweight, and works without anelectric power supply. These properties are suitable for Cosmic ray imaging.
Therefore, we are developing advanced nuclear emulsions and its analyzing
technologies for Cosmic ray imaging.

two-dimensional angular space that shows the detected direction of Cosmic
ray muons. The dashed circle in each image shows the direction of theupper chamber. Through this analysis, we validated our methodology byimaging the upper chamber from the lower chamber. This is the firstvalidation of imaging of a chamber inside a pyramid of 100 m-thicklimestone.

Measuring the Khufu Pyramid
We have been measuring the Khufu Pyramid since 2016. Nuclear
emulsions were installed in the Descending Corridor extending from themain entrance and the Queen’s Chamber (Fig. 2). We released our resultsfrom data from the Descending Corridor in 67 days (Fig. 3). It showed that
there is a clear difference from the center to north side when comparing
data versus simulation. This difference is over five sigmas, strongly
suggesting one or several unknown voids behind the north face. We aremeasuring from additional positions in the Descending Corridor to clearly
identify the shape and positons suggested by the anomaly and also analyzing
the data collected from the Queen’s Chamber.

Scanpyramids
We are applying Cosmic ray imag ing with nuclear emulsion
technologies to the measurement of pyramids through participation in aninternational scientific research project called “ScanPyramids,” which wasorganized mainly by Egypt’s Ministry of Antiquities and started in October
2015. So far in this project, the Bent Pyramid at Dahshur and Khufu
Pyramid at Giza have been measured.

Measuring the Bent Pyramid
Installation of nuclear emulsion detectors inside the Bent Pyramid at the Dahshur necropolis in Egypt. Aluminum plates, which fix nuclear emulsions,were placed horizontally on the ground inside the lower chamber to measure cosmic rays to validate imaging of the upper chamber.

Kunihiro MORISHIMA

We measured the Bent Pyramid to validate our methodolog y from
December 2015 to January 2016. Nuclear emulsions were produced in ourlaboratory at Nagoya University and sent to Cairo, Eg ypt. They were
installed inside the lower chamber in the Bent Pyramid (Fig. 1 (a), (b)),
with the installation area covering 3m2. The emulsions were collected anddeveloped after 40 days in Cairo, and then analyzed at Nagoya University
by a high speed automated scanning system called HTS. Through thesemeasurements, we took Cosmic ray muon images and compared them with

INTRODUCTION

Cosmic ray Imaging

Pyramids are gigantic stone architecture, which were built by ancient
Egyptians more than 4500 years ago. There are a lot of mysteries; “Who did build
them?” “Why and how built?” These are still unknown. In order to solve themysteries of Pyramids, various research missions with advanced non-destructive
technologies were conducted in past 50 years; radar scan, micro-gravity meter,robot and so on. However, these technologies have not enough searching abilityof depth, which can search up to several meters from these devices. Thus, if there
are any hidden structures deeply inside Pyramid, it could not be found. And also,
since they have not enough accurate imaging resolutions, its positions and shapes
can’t be clearly revealed if any anomalies are found.

X-ray imaging is a non-destructive imaging technology for viewing thehuman body or industrial materials with accurate imaging resolution.
However, X-rays are not able to penetrate a pyramid because its penetration
length is an order of meters in matter. Imaging using muons contained incosmic rays can realize visualization deeply inside gigantic objects likepyramids. Cosmic rays are fundamental particles or nucleus, which areproduced and accelerated by high energy astronomical phenomena in theuniverse like, for example, a supernova explosion. Interaction between cosmic
rays and atoms in the atmosphere produce secondary particles including
muons that have various energy levels. Muons have high penetration power in

Cosmic ray imaging is a very powerful technolog y for not only
archaeolog y as shown but also a wide variety of research fields: science,engineering, industry, infrastructure inspections, and more. In the near future,
we plan to apply nuclear emulsion technology to various applications andrealize Cosmic ray tomography, which is three-dimensional visualization frommany two-dimensional images inside a gigantic object.

gyptian pyramids built more than 4500 years ago still hold various mysteries. To take transmission images inside gigantic objectss like a pyramid, we aredeveloping Cosmic ray imaging technology with nuclear emulsions that can detect radiation emissions such as muons with very high accuracy. We have beenmeasuring the Bent Pyramid at the Dahshur necropolis and the Khufu Pyramid at Giza in Egypt since 2015. We validated our methodology by performing the firstimaging of the chamber inside the Bent Pyramid and found an anomaly behind the north entrance of the Khufu Pyramid.

The Effects on Ancient Maya Society of theCatastrophic Holocene-epoch Eruption of Ilopango

Geological Setting and Eruption of Ilopango Volcano

Social Networks as a Mitigation Strategy

The Zapotitán Valley, located in central El Salvador, has experienced
numerous explosive events over the past two millennia. One of these
volcanic events was the eruption of Ilopango Volcano. Although the datingand effects are still under discussion (1), this eruption occurred in the
5th—6th centuries AD, and is well known as the most catastrophic New
World eruption during the Holocene (2). For several decades, manyscholars have argued that the Ilopango eruption resulted in serious sudden
environmental changes and social problems in bordering regions, including
the Zapotitán Valley, with many sites being abandoned for at least half acentury or even a few centuries. Recent archaeological investigation of
SanAndrés in the Zapotitán Valley located c. 45km from Ilopango
Volcano, however, provides new insights and hypotheses regarding human
responses to its catastrophic eruption.

Networks are highly important socioeconomically in studies of ancientsocieties. At the same time, I highlight the importance of interregional andsocial networks to mitigate or overcome the damage of natural disasters.
Establishing and maintaining broader social networks contributes to mitigating
impacts over time and building resilient societies.

Volcanic Disaster and Construction of Monumental Architecture

Acrópolis, SanAndrés, El Salvador.

Akira ICHIKAWA

Based on archaeological evidence at SanAndrés, I hypothesize that theconstruction of monumental architecture was the motivating force behind
the recovery process from the catastrophic natural events. Our team
excavated the platform of Structure-5, the largest monumental architecture
at the site, which consists of a 13m-tall pyramid on top of a 7m-tall
platform, approximately 90m from north to south by 80m from east to
west. In general, Maya monumental architecture consists of a superimposedseries of constructions. Excavations revealed at least three construction
phases of the platform of Structure-5, the first of which is masonryarchitecture, which was constructed on top of volcanic ash layers of approx.
40cm thick spewed out in the eruption of Ilopango Volcano. This masonryarchitecture was covered by adobe construction. Previously, it wasconsidered that this earthen architecture was constructed several decades or
centuries after the catastrophic eruption. However, the masonr yarchitecture between the volcanic Ilopango ash and the adobe architecture
indicates that ancient people returned to the Zapotitán Valley more rapidly
than previously thought.

In the case of San Andrés, the masonry architecture mentione above is
key evidence in identifying support for the affected society from otherregions. Generally, in the southeastern Maya region (present-day El Salvador)both monumental and household architecture consisted of earthen materials
like adobe brick and mud plaster. Therefore, the masonry architecture thatwas constructed after the eruption should be regarded as significantly
different, because people needed new concepts, techniques, and labororganization for these construction activities. Furthermore, ceramic types also
dramatically changed after the eruption. I hypothesize that these data indicate
reconstruction support from another social group. One candidate is Quelepa,
located about 130km east of San Andrés, a settlement demonstrating similararchitectural components. Another possibility is Copán, one of the mostpowerful dynasties in the Classic Mayan realm, because San Andrés isconsidered to have been a satellite center of the Copán dynasty.

Concluding Remarks

Generally, defining direct connections between sudden environmental
change and cultural practices is complicated by a number of factors. However,volcanic products like thick ash fall are easily identified in archaeological sites.
In this sense, archaeological data on the gigantic eruption of Ilopango permit
a deeper discussion of the impact of natural disasters on human societies.
Although the hypothesis mentioned previously still needs to be verified,constructions of monumental architecture and social networks in ancient
Maya societies could have had special roles and probably played these roles in
response to natural disasters.

There is no doubt that natural disasters have brought sudden environmental and cultural changes, and have impacted current andd past human societies.
Archaeology provides excellent evidence on these topics. However, scholars have far too often simply emphasized natural disasters as dramatic and fatal
events, while human responses to and resilience in the face of natural disasters have been underestimated. Using the case study of the San Andrés site located in thesoutheastern Maya area, I highlight that we need to conduct careful case-by-case examinations of the effects of disasters.

INTRODUCTION
Natural disasters are an important concern for the modern world due tothe huge loss of life they cause. Although most natural disaster studies are still
dominated by natural scientists, social scientists have recently entered thisarena to better understand the human response to hazardous events andsudden environmental change. Archaeology is especially recognized as one of
the key disciplines in the advancement of disaster studies, since archaeologicalresearch can trace past human responses and the correlation of disasters with
cultural change from a long-term perspective.
Ironically, archaeologists often benefit from volcanic disasters because
the eruptive products of the eruption—such as pyroclastic flow, ash-fall

09 | IAR LETTER | March 2017

tephra, etc.—can preserve the artifacts of ancient daily lives in excellent
condition. In addition, the widespread emitted volcanic ash is often useful inaccurately dating finds. On the other hand, volcanoes are especially dangerous
hazards as they are unpredictable, sudden, and often have catastrophic effects
on current and past human societies. Scholars have often emphasized that
volcanic eruptions are critical events for human societies. However, we canalso observe long-term human activities in volcanic areas. The purpose of ourstudy is to better understand the correlation between volcanic activity andhuman response, as well as the resultant cultural and social shifts, based onarchaeological investigation of the southeastern Maya area, specifically the
Zapotitán Valley in El Salvador.

Masonry architecture constructed after the eruption of Ilopango Volcano.

Volcanoes are an important element in Maya cosmological concepts.
Monumental architecture usually represented a “sacred mountain” and was animportant symbol of community identity. Therefore, I consider that thecollaborative actions in constructing monumental architecture might havereinforced not only elite power but also the social relationships between
community members, in this case the victims of the eruption, and motivatedpeople during the post-eruption recovery process.

Enhanced plant photosynthesis and growththrough manipulation of stomatal apertures

growth by manipulating stomatal apertures via gene regulation in guard cells,
perhaps because of the difficulty of balancing the counteracting effects oftaking up CO2 while losing water vapor through the stomata (2).

Overexpression of H+-ATPase in Guard Cells Promotes Light-Induced
Stomatal Opening and Enhances the Photosynthetic Rate
Using the Guard Cell 1 (GC1) promoter, we successfully overexpressed
PHOT2 (an isoform of the blue-light receptor phototropin), AHA2 (atypical isoform of the plasma membrane H + -ATPase), AKT1 and KAT1
(isoforms of plasma membrane K+in channels) in guard cells, and thereby
obtained homo lines with high expression levels. Then, physiological studies
on Arabidopsis plants with the overexpressed components were performed.
Via isolation of the epidermis of 3- to 4-week-old mature leaves, stomatal
apertures were examined by microscope. The results showed that the stomatal
apertures of a plant with overexpressed AHA2 opened wider than those ofwild-type (WT) plants exposed to light illumination for 2.5 hours, but thesestomata closed in darkness just as those in the WT plants (Figure 2). It also
demonstrated that the stomata of the plants with overexpressed AHA2
opened more quickly than WT stomata over a period of 30 minutes ofillumination. In contrast, the overexpression of PHOT2, AKT1 and KAT1
had no effect on stomatal opening under light conditions. These results
indicated that H+-ATPase, not phototropins or K+in channels, is the limiting
factor in light-induced stomatal opening, and that increasing the amount of
H + -ATPase in guard cells increases the magnitude and speed of stomatal
opening (3).

Each stoma (pl. stomata) is controlled by a pair of special cells, named guard cells.
Stomata regulate gas exchange between the plant and the atmosphere.

stems in the reproductive stage (45 days old), including seeds, siliques, andflowers, of the plants with overexpressed AHA2 were approx. 36–41% greaterthan those of the WT plants under the same growth conditions. The numberof siliques per plant with overexpressed AHA2 was much greater than for the
WT plants, although the dry weights of individual siliques from the plants
with overexpressed AHA2 were comparable to those from the WT plants (3).
more the intention of the husbands, who typically had a larger ideal family size
than their wives.

Environmental response of plants with overexpressed H+-ATPase inguard cells
It should be mentioned that the increment of plant growth in the plants
with overexpressed AHA2 was obtained under laboratory conditions with proper
light, water, temperature, and CO2 concentration. However, in the field, theenvironmental factors are not always optimal for plant growth, and even worse,
certain abiotic and biotic stresses may occur. To investigate these factors, theplants with overexpressed AHA2 were grown under various unfavorable
conditions including low light, short daylight hours, and high CO2, and thestomatal apertures and plant growth were subsequently examined. The results
showed that the stomatal apertures of the plants with overexpressed AHA2 werestill larger than those of the WT plants under all the growing conditions.
However, since under low light and high CO2 conditions stomatal limitation did
not constitute a key limitation to photosynthesis, the superiority in growth was
negated under those two conditions. Only under the short-daylight-hours
condition did the plants with overexpressed AHA2 grow better and larger thanthe WT plants.
Meanwhile, the stress resistance of the plants with overexpressed AHA2 todrought and high temperature (considered as two major abiotic stresses) andpathogens (considered as the major biotic stress) were examined. It is notable thatthe plants with overexpressed AHA2 showed normal stress resistance, equivalent
to the WT plants, under all the abiotic and biotic stresses. These results provide
important additional information of how stomatal aperture manipulation
biotechnology can be used to promote stomatal opening and enhance plant
growth in the field.

hotosynthesis. Here, we
showed that overexpression the amount of plasma membrane H+-ATPase in guard cells had a significant effect on light-induced stomatal openings, andtherefore enhanced photosynthesis activity and plant growth. Application of this strategy in crops and fuel plants is expected to contribute greatly to the promotionof plant production and a sustainable low-carbon society.

INTRODUCTION
Photosynthesis is a fundamental process that has a close relationshipwith two critical worldwide problems: global climate change and foodshortage. How to improve the efficiency of photosynthesis of land plants topromote carbon dioxide (CO2) absorption and increase crop growth is a hot
topic for biologists. Leaves are the primary involved in plant photosynthesis.
As the leaf surface is virtually impermeable to air and water, key microscopic
pores—known as stomata—provide the major pathways for the diffusion ofCO2, O2, and water vapor between the ambient atmosphere and the interiorof the leaf. This facilitation of gas exchange by stomatal openings is one of themost essential processes in plant photosynthesis and transpiration.
Stomata are microscopic pores found on the surface of the leaves,

petioles, stem, and other aerial parts of a plant. Each stoma is bound by two
specialized cells in the epidermis, called “guard cells,” which regulate andcontrol the size of the stomatal aperture (see Figure 1). Light is one of theprincipal factors that stimulates stomatal opening, and various mechanisms
underlie stomatal opening in response to light. Recent studies on Arabidopsis
thaliana (a typical model plant) have revealed that the signaling pathway oflight induces stomatal opening involving at least three key components—
photoreceptors (phototropins), the plasma membrane H + -ATPase, andinward-rectifying K+ channels (K+in channels) (1). Therefore, it is expectedthat the overexpression of those three components in Arabidopsis guard cells
could induce stomatal opening to increase photosynthesis and plant growth.
However, no previous studies have determined stomatal effects on plant

Transgenic plant (plant with overexpressed AHA2) showed larger stomatal
apertures and a higher photosynthetic rate than wild-type plants

Then, the stomatal conductance (reflection of the stomatal gas-exchange
ability of intact leaves) and photosynthetic activity (photosynthetic rate) of
intact leaves of the plants with overexpressed AHA2 were examined in detailby a gas-exchange system. As expected, the stomatal conductance andphotosynthetic rate were significantly higher in the plants with overexpressed
AHA2 than in the WT plants (Figure 2). To determine whether the higher
photosynthetic rate of the plants with overexpressed AHA2 was due to theincreased stomatal opening, we examined the response curve between the CO2
assimilation rate and the leaf intercellular CO 2 concentration using a
gas-exchange system under saturated light conditions. The two curves were
almost coincident with each other, indicating that both the Rubisco
carboxylation capacity and the electron transport capacity were similar in the
WT and transgenic plants, but only the stomatal conductance was greater inthe plants with overexpressed AHA2. These results indicate that the enhanced
stomatal opening in the plants with overexpressed AHA2 contributed to theincreased photosynthetic rate (3).

The transgenic plant (plant with overexpressed AHA2) exhibited greater plant
growth in both the vegetative stage and the reproductive stage than thewild-type plant

Grown under conditions of sufficient light (about 200 μmol photon m-2s-1), the plants with overexpressed AHA2 exhibited superiority in plant
growth. They produced larger and increased numbers of rosette leaves withapprox. 42–63% greater fresh and dry weights than the WT plants in thevegetative stage (25 days old). Moreover, the dry weights of the total flowering

We evaluated our method for the purpose of plagiarism detection. The
experiment results show that our method detects more than 90% of
plagiarism in benchmark datasets, significantly outperforming existing
methods, which detect up to 70% of plagiarism. In addition, our method isable to detect templates and boilerplates, which are commonly used innewspapers and Web pages.
Besides improving the result quality, we also developed efficientindexing and optimization techniques to speed up our method for the
purpose of handling large volumes of text data. The experimental evaluationshows that our method equipped with these techniques is up to 12 times

We designed a platform to help users compose slides by reusing existingmaterials. The platform consists of three modules: (1) slide element search,(2) slide management, and (3) slide auto-generation.
For slide element search, due to the existence of different types of
elements in presentation slides, e.g., textual elements such as titles andsentences, and graphical elements such as images, charts, and diagrams, wedevelop a series of techniques to handle the variety of presentation slide
elements. For textual elements, users can input keywords or sentences tosearch, like when using a Web search engine. For graphical elements, users canselect an image on their disks or drag a rectangle area in a slide as a query(Figure 2). Then the module efficiently searches in their presentation files andshows relevant materials. It also supports the feature of approximate search sothat users do not have to remember the materials exactly.
Slide management is a module with which users can manage theirpresentation files in terms of their relationships, e.g., multiple versions,summaries, etc. The files are visualized in a network (Figure 3). Two files areontent reuse is a common practice in an era when electronic documents prevail. For example, when composing presentation slides, people often create newfiles by reusing the materials in existing slides instead of starting from scratch. Investigating content reuse in electronic documents may assist in a wide range ofapplications, including plagiarism detection, near-duplicate Web page removal, text summary generation and presentation slide composition. This study covers twotasks: content reuse detection in text documents and content reuse for presentation slide composition. We addressed several important technical issues and proposed
effective methods with high efficiency. On the basis of the proposed methods, prototype systems with user-friendly interfaces were developed for practical use.

connected if common materials are identified. Users can easily find out whichfiles reuse materials from others and which elements are reused. In addition,
users can drill down the reused elements to see their timelines, i.e., which filethey originate from and in which files their content has been reused andwhen.
The slide auto-generation module saves users from making slides page by
page. First, the users specify the titles for each slide. They may input a title by
the keyboard or choose from a range of common titles, such as "related work,""experiments," or "conclusions" for academic presentations. They then selectelements using the slide element search module, and assign these elements tothe pages. Finally, they adjust the slide layouts, e.g., the positions of the text
and images. Presentation slides are automatically generated after these steps. A
set of example slides generated by this module is shown in Figure 4.
On the basis of the above modules, we design prototype systems withuser-friendly interfaces that can easily be used in a company with common aslide composition tool such as Microsoft PowerPoint.

INTRODUCTION
One of the main issues accompanying the growing popularity ofelectronic documents is the existence of reused contents. For example, reused
text may exist in academic papers, dissertations, etc. People may plagiarize
others' work by copying text segments from various sources and making a few
modifications to avoid detection. Another example is that when composing
presentation slides, 97% of people compose presentation slides by reusing
existing materials rather than starting from scratch [2]. One of the primaryreasons for such reuse is to repurpose the contents of existing slides fordifferent audiences, events, formats, etc. In this study, we looked at content
reuse for two common types of documents: text and multimedia, and focused

on the following two tasks: (1) content reuse detection in text documents, and(2) content reuse for presentation slide composition.

Content reuse detection in text documents
Although there have been many existing solutions to the detection ofreused contents, e.g., [3, 4], they can be easily fooled by minor modifications(Figure 1), such as reorganizing sentences, replacing words with synonyms,
etc. Consequently, reused contents with modifications are often missed bythese methods, and hence the quality of detection is not satisfactory.
Seeing the limitations of prior solutions, we propose a new approach bydetecting similar text segments. Our method is not only insusceptible to word

Activity & NewsThe Nagoya University Lecture 2016

IAR Lecture

IAR Symposium

The Nagoya University Lecture is an annual event which is the mostimportant academic lecture at the University, and is hosted by the President.
The lecturers are selected from international researchers of the highest caliber
and all lectures are open to the general public.
On November 19, 2016, the Nagoya University Lecture was held at the
Toyoda Auditorium, organized by the Institute for Advanced Research of
Nagoya University and Chunichi Shinbun Co., Ltd.
This year, the Lectureship was awarded to Kenichi Miyamoto, Osaka City
University professor emeritus and Shiga University professor emeritus who is
an internationally recognized pioneer in the field of environmental economics.
Professor Miyamoto is known for coining the Japanese word “kōgai,”
which is literally translated as “public harm” and refers to environmental
pollution. His lecture gained a lot of public attention and attracted more than
500 people.
Shunichi Teranishi, a professor at Teikyo University and emeritus professor
at Hitotsubashi University also joined the lecture and gave a speech on thehistory of environmental pollution after World War II, the increase of pollution
and environmental problems in Asia, particularly emphasizing the role ofProfessor Miyamoto in the development of research in this field andintroducing a new definition – so-called “Miyamoto economic thought”.
According to Prof. Teranishi, a well-known saying “There is no wealth, but life”
by John Ruskin in the light of Prof. Miyamoto`s research may definitely beinterpreted as “There is no wealth, but life and environment!".
Professor Miyamoto`s lecture was devoted to sustainable society withhistorical lessons learnt after WWII. In the lecture, he pursued the issue ofpollution as a price paid for Japan’s period of rapid economic growth starting in
the 1960s, and explained the issues of pollution he has studied and examinedin the field for over half a century. Professor Miyamoto also mentioned his
work to find solutions to issues such as Japan’s “four big pollution diseases,”
including so-called “Yokkaichi asthma” caused by sulfur dioxide pollution, as
well as his views on the approaches to these issues - from the standpoint ofrespect for basic human rights and the independence of local governments.
It was an excellent opportunity for the public to find out more about
environmental problems and the possible ways for their solution from themost experienced and outstanding researcher, who presented his lecture in avery comprehensible and easy to understand manner.
The questionnaires collected after Prof. Miyamoto’s lecture reflected thegreat interest and concern the majority of participants had regarding
environmental issues. Most people, expressing their deep gratitude to thelecturer, confirmed the belief that environmental problems are among thosethat need immediate solution.
At the end of the lecture Prof. Miyamoto shared his motto with young
researchers: - “The unique purpose of science is to ease the hardships ofhumankind’s existence” – a truth that we all need to remember.

The IAR lectures are the most important academic lectures at the Institute.
They target University researchers and cover research of extraordinary excellencefrom within and outside the University. They are open to the general public. The 9th
IAR Lecture on the Problems in Exchange of History of Thoughts in East Asia washeld on December 16, 2016 at the Noyori Conference Hall. Nagoya-IAR has had ajoint research project with several Universities in Asia for a number of years. At thelecture, a leader of this joint research project Professor Chun-chieh Huang from
National Taiwan University and research members gave lectures. Those lectures
were: : “The history of collaborative research and professor Huang” by Professor
Takaho Ando (Chubu University), “The methods of exchange of history of thoughts
in East Asia and problems – East Asia・Confucianism・Present time” by Associate
Professor Fumihiko Kawajiri (Aichi Prefectural University), “Western musicians ofJapan and the spirit of Confucianism” by Professor Jianying Ou (Niigata University ofInternational and Information Studies), “The media transmission of wisdom and thehistory of thoughts” by Professor Masashi Tsujimoto (National Taiwan University)and a keynote lecture “The vision of East Asian Confucianism and the problems of
its methodology” by Professor Chun-chien HUANG (National Taiwan University).

We organized IAR symposiums starting from 2016. The symposiums aim atcommunicating the established, novel and cutting-edge research at Nagoya
University to all its members. We set three different fields, human and social
science, natural science and engineering, and medicine and biology. The first IAR
symposium “Creation and Inheritance of Knowledge in Humanities andSociology” was held on June 29, 2016. Six assistant/associate professors and six
full professors who were chosen as the representatives of the Graduate School ofLetters, Graduate School of Education and Human Development, Graduate
School of Law, Graduate School of Economics, Graduate School of International
Development and Graduate School of Languages and Cultures presented theirresearch results, and about 100 people attended the symposium.

Foreign PI Fellowship Program
The Foreign Principal Investigator (PI) Fellowship program is a program
inviting excellent researchers from foreign countries with outstanding researchachievements for three to four months’ fellowship, to promote the University’s
academic research. In the academic year 2016, Prof. Enrico Martinoia (Professorof the Institute Plant Biology, Zurich University) and Prof. Jean-Noël Robert(Professor of Philology of Japanese Civilization, Collège de France) were selected
for this fellowship. While they were visiting Nagoya University, they discussed
collaborative research with PIs in Nagoya University. Also, they contributed tothe education of young researchers
by giving advice and lectures.
Professor Martinoia gave a lecture“Plant ABC transporters: fromdetoxification to hormone transport”
and Prof. Jean-Noël Robert gave alecture “La hieroglossie japonaise
comme modele langagier”.

Ryoji Noyori Academy Salon
Since January 2013, University Prof. Ryoji Noyori, a 2001 Nobel Laureate in
Chemistry, has contributed numerous articles to "Kamitsubute" in the Japanesedaily newspaper Chunichi Shimbun. Based on these articles, he holds regularacademic discussions with students. In 2016, four (the 19th to 22th) Ryoji Noyori
Academy salons were held. Prof. Noyori and students from different academic fields
discussed various topics. The topics were “Supercomputers and the Future” (19th),“Civilization to Be Developed on One’s Culture” (20th), “Multiplication Can Create
New Value” (21th) and “Only-one and Number-one” (22th).
