PREFACE

IIS has established a Regional Network Office for Urban Safety (RNUS) at SET, AIT since 2002 anddispatched young faculty members from Japan to Thailand to work for education and research
including urban safety, remote sensing and GIS, infrastructure health assessment, flood risk monitoring.
RNUS also serves to organize seminars and arrange IIS/U-Tokyo alumni parties every year. We
recognize RNUS as one the core international liaison research offices in Paris and New York.
On the first day, Dr. Pennung Warnitchai, Dean of the Department of Civil Engineering, AIT, presented“Vibration control of buildings and structures-an Overview,” and on the second day, Dr. Yudai Homma,
Associate Professor of the Institute, presented “Mathematical Model for Social Distancing-Close
relationship with architectural planning”, and on the third day, Professor Wataru Takeuchi gave alecture titled “Geospatical technologies towards one world, one health and earth”.
This is the first event in the last 13 years which is fully organized via online conference style. I wasconcerned about the connection from countries with unstable internet environments, but themoderator from AIT was able to share the questions on chat and the discussion among the students
progressed more than expected. There were 36 student presenters from 13 countries, including
Thailand, Japan, Myanmar, India, Sri Lanka, Cambodia, Peru, Egypt, Indonesia, Nepal, China, Korea, and
the Philippines, for a total of 132 participants over the three days, including the audience. The
activities of the RNUS Thailand Office, which has been led by the International Center for Urban Safety
Engineering (ICUS), will be expanded in cooperation with the Office of International Industry-Academia
Collaboration.
May I ask each of you here today to lend your strength and support to AIT and IIS/UTokyo as it strives
to enhance and expand ever-growing friendship and scientific exchange activities for excellent
scientific researchers.
Thank you very much, Kopun-krap, Arigato-gozaimasu.

Coastal Cities under Waterlogging
Xinwei Xi, Tsinghua University, China, 3rd grades of postgraduate

Urban waterlogging is a common urban disaster, and its destructive power is a major problem
that restricts urban safety and social and economic development. This problem is more
obvious in coastal cities due to frequent rainfall. How to quickly assess the safety andresilience of urban waterlogging in the case of insufficient numbers has become a problem
that needs to be studied. This paper uses the combination of multi-criteria decision-making
and Markov chain Monte Carlo method to give a solution.
As a typical coastal city in China and an internationally renowned city, Shenzhen has high rainfall and low altitude,
as well as annual rainfall in the typhoon season, and waterlogging as a common disaster, posing challenges tosecurity and resilience. So we took Shenzhen as a case, combined multi-criteria decision-making and Markov chain
Monte Carlo method to quickly assess and optimize the waterlogging resilience.
The first part uses a multi-criteria decision-making scheme, based on GIS raster hydrological modeling, and canquickly assess the city's waterlogging safety resilience level under stable rainfall in the absence of urban drainage
data. Multi-criteria decision-making methods are used to evaluate and score the waterlogging resilience level, carryout sensitivity analysis to streamline indicators, and consider regional conditions, risk preferences and moving
window sizes to classify waterlogging safety resilience.

The second part is based on the results of the previous chapter, using Markov chain Monte Carlo method tosimulate the dynamic changes in the resilience level of Shenzhen in the rainy season. The combination of MCMC
method and difference improves the speed of simulation and convergence, and optimizes decision-making forresilience assessment. The recovery probabilities of different waterlogging resilience levels are converged, therecovery process is simulated, and sensitivity analysis is performed.

Based on the research conclusions, suggestions for improving the waterlogging resilience level of coastal cities are
put forward and applied to actual production applications.

A Post-Disaster Operational Planning Process for Transit-Oriented
Development with Secured Access to Livelihood Recovery
Martin Garcia-Fry, Architect, Peru, Master Course
After the 2010 Merapi Volcano eruption, many villages were relocated in semi-urban settlements separated from their earlier livelihoods andwith few options for diversification. Post-disaster resettlement is dependent on people’s access to livelihoods as a means for short- and longterm recovery. The purpose of this study is to describe a systematic process of urbanization during the first ten years of recovery based on
Transit-Oriented Development (TOD) that produces employment opportunities and less travel expenditures. In 2019, a field survey was
conducted in the largest resettlement site of the Sleman Regency in Yogyakarta Province to evaluate the state of recovery; socio-demographic
and land use data was subsequently processed to forecast urban development into the year 2030. Travel routines were simulated for 2019 and2030 comparatively to quantify travel efficiency and ease of access to economic growth using urban form indices. The TOD provided 624 fulltime jobs and consequently, 41,850m2 of residential demand due to concentrated building growth. The case study saw a 57% increase ofneighborhood shopping and 21% new full-time job attainment for the displaced community. Efficiency reduced 33% of travel within the newsettlement and a 57% reduction in total. Fuel consumption was decreased by 44%, equal to 109,752 grams of carbon dioxide (CO2). A balancein mobility modes was achieved with motorcycles (36%), public transportation (32%), and walking (32%) for the whole settlement. These
results indicate inexpensive sustainable development with exposure to 3.2 times more transit volume allowing economies of scale to generate
livelihood opportunities during post-disaster recovery.

i would prefer to make much more sections for research fields to be contact with more specialist
Is it possible to extend the presentation time? I think 5 minutes is not enough to explain a whole research
It was very helpful to clearly present the results of various faults, not just the sagaing fault.

Q3. Any suggestions for this seminar?
1

More time for presentation

2
3

It's better to have online presentation rather than video presentation

4
5

Instead of poster if the presentations can be presented in ppt format it will be more clear to see the content.
Time for video presentation is too short.
From my point of view, this seminar is of great value in that it provides a platform for students in different countries to share
their research achievements and communicate with each other. I think the software used for the seminar (zoom） could be
improved in its video and audio connection

6

The poster size can be made more bigger for video based presentation.

78each poster should be presented more than 10 mins included q&a.

9

15

It was well organised and smooth. Great work and efforts by ICUS & IIS
team.
I think it went pretty well for 5-min presentations. Moreover, presentation skills were developed, thank you!
Poster font were very small and Five minute presentation is not enoughIn the past seminar, everything was perfect. In the further seminar, could we invite universities in EU and US to join us? If we
can do this, it will be more beneficial to students.
I think PPT is better than posters online.
We make a power point , not only poster.
Since it was a remote seminar, I thought it would be better to present it with PowerPoint slides rather than posters.
The session I joined was occupied by a lot of Thais, and the discussion between Thais and Japanese was very rare. Sessions
should be more diverse.

16

I think it would be great to include the researches which will be the combination of social sciences and engineering. Thank youvery much.

17

It would have been nice if we could have used the breakout room function to break up into several groups and have students
interact with each other.

18

According to Q2, we can limited the presentation time and number of slides for all presenters to follow the rule
Moreover, it's really good place for student to practice and present through the online method. Great activity!

19

The seminar is effective to share and discuss about the new innovation but in the time limit of presentation affected theaudiences to understand the research because presenter had to present in time limit

20

If next year we need to do it online again, please consider the different way to present the project. Using the poster is hard to
explain the detail and no one could understand the project clearly.

21

It would be easy for some presenters if 5mins presentation can be submitted as a video file without recording it in PowerPoint.
It allows the presenter to make presentation more clearer in there own way.

22
23

Should not use powerpoint for poster online presentation
The seminar is effective to share and discuss about the new innovation but in the time limit of presentation affected theaudiences to understand the research because presenter had to present in time limit

24

Unfortunately, the seminar was performed via online platform so they are our obstructions about the internet connection also
the participants need to submit the presentation video and some have problems with this step

25
26

providing much more time for presentation
Hopefully, this seminar can be held offline. And for me, recording the presentation is a new things. I prefer to directly present
intead of record the presentation. Overall, this seminar give me a good opportunity, during this pandemic.

27
28

I think it is better to use PowerPoint instead of posters for online presentations.
For many people, online seminars are good because they are easy to attend.
Some might say that face-to-face is better...
