㻌 Reinforced concrete structures have been regarded as
so excellent type of infrastructure because of their highdurability guaranteed by the adequate design andconstruction. However, these days, a part of such
structures have showed premature deterioration due tosevere attack of environmental factors. Fig.1 shows anexample of structures heavily damaged by the chloride
attack supplied by sea water.
As the effective an repair method against steel
corrosion in concrete as shown in the case of chloride
attack, the electrochemical repair method has been
focused. The principle of this method is shown in Fig.2.
Electrochemical migration of ions in concrete or
penetration of alkali solution into concrete results inimprovement of the durability of structures.
Recently, our research team has tried electrochemical
penetration of lithium ions which can suppress concrete
expansion and cracking due to ASR. Fig.3 shows
successful suppression effect achieved by the proposed
electrochemical method.

Content:
The research question is how much do heterogeneity and local
interaction influence mobility shift with the policy for sustainabletransport. A multi-agent mobility shift simulation model thatconsiders heterogeneity and local interaction is developed. For thispurpose, the stated preference (SP) for mode change and purchase
CEV policies is investigated via a questionnaire survey. The
proposed multi-agent simulation model includes the decision
process of the agent regarding mobility shift, the social influence
process in the social network, and the CO2 emission process. The
decision process for commuting mode is modeled using thehierarchical Bayesian method mainly to describe the heterogeneityof the influence of the local mode share. The day-to-day dynamics
of commuting mode choice and the purchase of CEVs
corresponding to the transport policy are estimated using the
proposed multi-agent simulation model.
The results confirm that the heterogeneity of influence on social
conformity should be considered in the modeling of modal shift as
both conformity effects and non-conformity effects are observed.
However, the assumption of homogeneous commuters might cause
estimates that are too high, since the heterogeneity of commuters
decreases the share of the sustainable transport mode.
Furthermore, the green tax policy is confirmed to be suitable for
maximizing the reduction rate of CO2 emissions, as pricing based on
fuel consumption maximizes reduction efficiency.

Content:: Since good quality natural aggregate are
exhausting, it is important that industrial recycled productand by-products are used as an aggregate for concrete. In
Japan, use of recycled aggregate are proposed. Although,strength and durability of recycled aggregate concrete arelower than normal aggregate concrete, recycled aggregate
has not been major. In order to improve physical propertiesof concrete using recycled coarse aggregate, blast furnace
slag sand were proposed. Recently, blast furnace slag
sand is expected to improve durability, freezing andthawing damage of concreters in Japan. As properties offresh and harden concrete bleeding, compressive strengthand resistance to freezing and thawing that obtained by
rapid freezing and thawing test using liquid nitrogen ishigh-loader than JIS A 1148 were investigated. As a result,the concrete using treated low-class recycled coarse
aggregate and 50 % or 30 % replacement of crushed sandwith blast furnace slag sand gave the good results, interms of bleeding, resistance to freezing and thawing.

a severe disaster such as that we have been experienced in
the 2011 Tohoku earthquake. In order to mitigate the tsunami
damage, physical behavior of tsunami should be investigatedby a broad field of study.
We develop an accurate and highͲspeed tsunami simulation
software called JAGURS which was optimized very much onhighͲperformance parallel computers such as the K computer
and the Earth Simulator in Japan. JAGURS is not only highͲspeed, but also more accurate than the conventional tsunami
software. The figures are seaͲsurface fluctuations simulatedwith (a) the longͲwave equations and (b) the dispersive wave
equations near the Sendai coast 90 minutes after the 2011
Tohoku earthquake. We can see dispersive wave trains(soliton fissions) in (b) but not in (a). Actually, in the area, thesoliton fissions were recorded from a helicopter. We also
investigate a real time tsunami prediction system by a
combination of highͲspeed calculation and cuttingͲedge

Content:㻌 Dams and falling works usually contribute river bed
stabilisation, but they at the same time bring some
defects on river environments, such as yielding a stillwater section, depositing sediments there, andpreventing fish migrations. Several engineering
schemes can be considered to improve such asituation, i.e. full removal, height reduction,
redesigning such as slit-type, etc. These schemes,
however, naturally cause bed degradation in the
upstream reach and abrupt increase of sedimentsupply in the downstream reach, then it possibly leads
to channel instability. Owing to the lack of information
on river bed change following dam removal or falling
works improvement, these schemes have not widelyadopted in real rivers.
A series of experiments were conducted to study
effects of falling works improvement on scouring and
bed evolution around it. Water surface profiles,
velocity distributions and bed configurations at an
equilibrium condition were measured.

Proposedpixel-freemethod㻌 Kinematometry is a newly coined word, which means amethod to obtain kinematic information, i.e., movement anddeformation, especially strains of geotechnical objects. A new
precise matching algorithm was developed. The algorithm
provides completed pixel-free measurements, which caneliminate accumulation of errors produced in successive
photometry analysis. Errors in strain calculation arising fromthe discrete structure of conventional raster image data arealso avoided by means of this pixel-free algorithm having a0.001 pixel of resolution.
Accuracy of the algorithm was examined by using both
artificially deformed images and actually translated images.
The results showed that the errors were less than 0.2 pixels
for artificially deformed images within 20% of strain, while 0.05
pixels for translated images.
Figures presented here are examples of the applications:shear banding under strip footing and crack opening. Aliasing
shear banding shown by conventional subpixel methods
vanishes by using proposed pixel-free method. Precise
matching method provides clear image of crack opening in
reinforced concrete structures subjected combined cyclicloading.

In Kanayama River, a total of 28 dams are present inless than a 5 km stretch. Widened streams and ripariandeforestation resulted in warming the stream
temperatures.

Content:
㻌 We investigated population abundance of native Dolly Varden
Salvelinus malma in mountain streams of northern Japan in relation
to several physical habitat characteristics including watertemperatures and small dams. Hokkaido Island is the world’s
southern most distribution margin of native Dolly Varden, and it has
been projected that many populations would suffer from severe
summer stream temperature warming due to habitat alterations
such as construction of erosion- and flood-control dams andpotential impacts of global climatic warming. However, there has
been little effort in obtaining basic information on the species’
population abundance and thermal habitat over successive years.
Therefore, in an attempt to initiate long-term research, we begancollecting fish data by electrofishing and temperature data by
installationoftemperatureloggersin
37 streams in 2000. We found that several Dolly Varden
populations
showedsigns
of recruitment failures among years and less abundance in streams
where summer maximum stream temperatures far exceeded thespecies’ thermal tolerance of around 16 Ț. In this paper, we will
primarily focus on our findings during 1999-2001 and 2006-2013
field surveys.

㻌 Making stage-discharge curve (H-Q curve) that uses
calculating river flow rate is very time-consuming. Then,a H-Q curve making method that used the observed
rainfall, the water level data, and the runoff model wasdeveloped. A quadratic function that represented the H-Q
relation in the river channel was built into the runoff
model. When the observed water level hydrographs
during a flood event was reproduced by the model, theH-Q curve was established. (Fig.1)
The method was applied to some water level andflowing quantity observation stations in Shikoku in WestJapan . The established H-Q curve was compared with
the H-Q curve based on the runoff observation. The error
margin of the established H-Q curve and the observed
was about 10% or less. (Fig.2)
The proposed method can be used to verify and adjust
the observed H-Q curve that may lead to an unsatisfied
water budget of rainfall and discharge for the basin.

䠏䠅An example of Multi-Agent Simulation:MAS result

Content:
Public procurement system such as Overall-Evaluation dynamically has
been changed on public works in Japan. However some characteristics of
Bidding-Strategy and procurement system have not enough clarified.
We analyze the influence that the change of the public procurement
system gives to the Bidding-Strategy of the construction company.
1) Question paper survey of Japanese construction company's bidding
behaviors : In order to know the consciousness of Japanese construction
company's bidding behaviors, a question paper survey is conducted which
is similar to three previous experiential study papers of U.S. and U.K. The
questionnaires are made to unique to Japanese domestic circumstances.
The main questionnaire is the importance evaluation to 36 factor keywords
in two situations: one is for the determination of participation in and, anotheris the price determination (percent markup) for the bid.

2) Monitoring bidding data : In this study, we try to monitoring bidding data
between accumulated estimation method and the unit price estimation
method. The bidding data were special period. It has two patterns to methodof calculating predetermined. As a result, in the case of accumulated
estimation method increase participants and decrease win bit rate. The
other way around, decrease participants and increase win bit rate. So we
make a revolve equation to method of calculating an estimate price andcheck the effect of the unit price estimation method. We showed that theunit price estimation method has effect of decrease predetermined.
3) Simulation model focused on Biding-Strategy: This study attempt toanalysis for a system dynamics and mechanism of Overall-Evaluation by
developing new simulation model focused on Biding-Strategy, to propose
some improvement scenario.
