Abstract
Vaccines are very sensitive to deterioration if poorly maintained at the right temperature.
They must be kept at a suitable temperature, 2-8 degrees Celsius. So, we decided to invent a
vaccine storage box with dry ice to maintain the quality of the vaccine and make it easier to
transport vaccines to remote areas. The vaccine storage box measures the internal
temperature of the box using the DHT 21, which measures -40 to 80 degrees Celsius, and the
box has dry ice as a cooling generator. The storage box can control the temperature by using
the Arduino IDE program that controls the fan to adjust the temperature in the box to be
stable. If the temperature is higher than 8 or lower than 2 degrees, the system will send a
message to the LINE application of the user, and at the same time also make an alarm sound
at the box. From the experiment, when we put 6*6 inch dry ice in the box, the temperature
can be adjusted between 2-8 degrees for 15-20 minutes, and the temperature can be
maintained for 9-12 hours.

Abstract
The elderly are an essential part of society, and the physical decline that comes with aging
has been a source of concern for us. One of the most obvious signs of deterioration is fatigue
and weakness of hand muscles, which can lead to a variety of health issues. This concept
inspired us to create a device that helps to slow down the deterioration of the hand muscles
called "Fine Motor Exercise Equipment for the Elderly," a tool that can be used in everyday
life due to the device's convenience and ease of use, as well as the enjoyment it would provide
to the user. Furthermore, aging society has been growing throughout the world rapidly, to
the point where we can no longer ignore it. We can only do our best to prepare ourselves and
make this society better than it has ever been for them. The development of Fine Motor
Exercise Equipment for the Elderly aims to improve hand and finger dexterity, lowering the
risk of developing muscular dystrophy and other degenerative diseases.

Abstract
We are developing a small device named KME that emulates a keyboard and a mouse and
operates Bluetooth devices. Although it can only handle a limited number of signals, it is
possible to modularize the input and output through the KME, and this small device makes
it possible to optimize this system for each user. It is expected to be used as a welfare device
for the elderly and disabled. This time, in order to understand the actual problems of people
with disabilities, we visited facilities that support people with disabilities and have
considered problems and solutions. For example, people with physical disabilities have
difficulty in communicating their intentions, but we think that KME can be used to assist
them in this regard. KME can also be used to help people with intellectual disabilities learn
the cause- and-effect relationships that are necessary for communicating their intentions. We
decided the purpose of this study is to develop an assistive device using KME and to consider
a mechanism for introducing such a device. In introducing assistive devices, the input
switches (buttons, touch switches, various input devices for support, etc.), KME software,
and the way of output (moving plush toys, sound, vibration, light) must be optimized
according to the characteristics of the individual. We found that it is necessary proceeding
with development through repeated hypothesis setting and testing, and providing support in
accordance with each objective and method.

Abstract

In a world where technology moves rapidly the design and execution of most fire alarms
have stood still with them not providing much information other than a generalized
emergency sound and with the occupants not knowing where or what caused the sound. It
could easily lead to panic and a sense of confusion. Furthermore, traditional alarms also lack
in accuracy which so many times had led to false alarms. Further decreasing people’s trust
in such systems. In order to combat these problems and create a hassle-free alarm system
with interconnected alarms working together. Thus, we then thoroughly researched parts and
similar devices to give us an understanding in how fire alarm systems usually work before
we decided on parts and techniques to use. Choosing the processer of our project was also
very important on one hand choosing one too powerful (e.g., The raspberry pi) would mean
we had a high ceiling for features but would cripple our efficiency but choosing a low
performance chip (e.g., Esp8266) would give us high efficiency but a lower ceiling for
features. So, we decided to balance out the two aspects and chose the Espressif esp32 chipset.
After the parts have been selected, we began working on modelling our case to be the exact
size for our components having been refined and adjusted until it was the correct size. After
that we spent the next few months writing and testing the code, making sure it would work
flawlessly across multiple units. Once the code was operational, we then tested one system
making sure all the components would work together without a hitch and components which
caused problems were switched out. Finally, we assembled multiple alarms to test the system
and fix any problems that had arose.

Abstract
The increasing number of elderly persons and decreasing birth rate in Thailand are affected
by economic downturn. Most of elderly persons have underlying diseases, so they need to
take the medicines everyday. The project aims to create automatic drugs dispenser with
distress call system via linefor elderly persons in order to solve the problem of forgetting to
take medicines, not taking the medicines in time, and asking for help in emergencies. From
testing operation of device, it can dispense to medicines at the specified times, inform
caregivers by sending alert messages when the drugs are taken. Whenever the elderly persons
don’t take the medicines; the device will send notification by audible alert and flashing light
until they have taken medicines. For distress call system, the program is written on Kidbright;
this command system works when the elderly persons press the switch on the device. Then
the alert messages of asking for help are sent to the caregivers, and the device makes sound
signal and flashing light to remind also. This emergency call does not stop until the
caregivers are there and help the elderly immediately. For packing the pills, each tablet which
is not removed from packaging to prevent moisture is cut from the panel, after that pills of
each meal are contained in the pill boxes. The automatic drugs dispenser can contain up to
18 pill boxes in a batch and dispense the pills only before meals and after meals.

Abstract
People today share their messages, comments, and opinions heavily through social networks.
Consequently, social media platforms, which have users around the world, house messages
of all kinds: positive, neutral, and negative. Positive texts tend to convey pleasing meanings
such as displaying gratitude, giving hope, or showing love, while negative texts are likely to
make people feel unpleasant, for instance, by insulting others. Users who encounter these
negative messages often feel uncomfortable, anxious, lacking self-esteem, and even
depressed. Therefore, we decided to build a Chrome Extension called Negative Filter, which
can filter negative messages from users' Twitter feeds, one of the most used social media
platforms. We trained machine learning models to classify sentiments of the texts using three
different algorithms: Naïve Bayes, Random Forest, and Transfer Learning. We chose and
used the best model as an application base. After the model evaluation, the best algorithm is
Transfer Learning, which has 83% accuracy. Followed by Random Forest and Naïve Bayes,
which have 66% and 60% accuracy, respectively. For practical use, we test the performance
test at 100 concurrent users in the system. The average response time is about 4.1 seconds.
This led to the conclusion that the application could correctly classify the emotions of the
text and possibly be used by a large group of people.

Abstract

An economically significant crop is sweet young coconut, which is regarded as a special
plant in Thailand. The Thai market has a strong demand for sweet young coconuts and
overseas in the consumption of coconut meat, the production of coconut milk, and the usage
of coconut husks and shells. When shipping coconuts that are not standardized, it is difficult
to determine how much coconut meat is present, and it takes time to determine whether the
coconut is ripe, which lowers market demand and puts middlemen under pressure. A sweet
young coconut meat inspection device was designed to estimate the harvest period of each
coconut by examining the color of the coconut bottom. The color change of the coconut
bottom suggests the right time of coconut harvest. This device, however, has limitations. The
color of coconut bottoms may be subject to natural light and photo sharpness, which results
from the distance between the camera and coconuts. The sweet young coconut meat
inspection device was developed into a smart phone application which was connected to the
smart phone’s high-quality built-in camera. The zooming feature allowed a sharper picture
when the coconut was high up on the tree and thus enabled the system to calculate the
estimated harvest period more accurately. The created application adopted deep learning and
image augmentation techniques. The study was divided into two parts. In the first part, the
training and testing were done with binary cross-entropy. It was found that the test error
value was 0.1207. In the second part, the model accuracy test was calculated by dividing the
number of correct predictions by the number of total predictions—the total number of
pictures used. The accuracy value was 9 5 % . The result showed that the developed
application can help farmers quickly and more accurately identify ready-to-harvest coconuts.

Abstract
Internet crimes against children are a growing concern globally, and children can become
involved in crime when adults attempt to impersonate children in online communication.
Programming is the creation of a set of processing procedures to make a computer perform
an intended operation. Deep learning is a deep neural network in which a program
automatically extracts features from data without human input. This technology can be
applied to protect children from Internet crimes that occur when adults impersonate children.
The purpose of this experiment is to be able to distinguish between characters written by
children and adults. Using a Neural Net Computer (NNC), a deep learning tool, we created
a program using 5,200 data points collected from training data provided by children and
adults. The results of using separate validation data could successfully verify the accuracy
of 1560 data points, a rate of 73%. Therefore, in the future, getting people to write
handwritten alphabet letters before communicating on the Internet could help prevent crime
involving children at an earlier stage.

Abstract
According to a study, “The study of problems and demand of the blinds at Sampran blinds
woman learning site, Nakhon Pathom, Thailand”, shows that the difficulty of traveling is off
the charts, especially the walking. In Thailand, they were rarely installed blind guidance on the
paths beside the smaller roads. Even if they were, most of them are blocked by obstacles such
as trees or signs. These obstacles can cause harmful accidents to the blinds and injure their
heads. Looking into this problem, the researchers want to create an innovation to help the blinds
walking on the path without getting their heads hit by obstacles by using the wave reflection.
The obstacle detecting helmet utilised four ultrasonic sensors to detect the obstacles and 4
buzzers to alarm the user as the obstacles got closer. It is also made of light material for
reducing the weight, and includes an electromagnetic defending pad underneath for preventing
the effect of electromagnetic waves on the user. Due to COVID-19 pandemic, the researchers
are not able to test the helmet with the volunteers yet. The testing was carried out by student
volunteers instead. The testing result shows that the obstacle detecting helmet, using the
reflection of the wave, can detect the obstacle with high accuracy while measuring the distance
with a 4.72% of error. From the interview, the volunteers, who were blindfolded, said they
were digesting the sound of buzzers from different directions and they can correctly dodged
the obstacles.

Abstract
Clothing is an essential factor for every human being. People are more interested in buying
apparel nowadays, which is causing the apparel market to grow more and more. New
technologies are used for product development, store development, and brand image
development. As a result, the authors create a small pedal that can tell shoe size, shirt size, and
bust size by using multiple infrared sensors controlled by an Arduino board to measure foot
length and send the value to a Python program that calculates shoe size in standard US and UK
sizes. Furthermore, we gathered the mathematical relationships of 13-18-year-old male
students' foot length, weight, and bust. We created a correlation equation between foot length,
weight, and chest circumference, enabling our inventions to calculate shirt size and chest
length. In addition, to enhance the beauty and good image of the shop, we have created a
program interface that is easy to use and beautiful. We believe that our inventions will greatly
speed up the selection of shirt and shoe sizes, thereby reducing the damage of try-on products.
We also believe that our inventions can create a modern image for a brand and a store.

Abstract
Most visually impaired people have difficulty using their mobile phones to chat messages
because they can’t see their mobile phone screens. This makes it difficult to enter text.
Although it can be used to communicate. But people with disabilities should also be allowed
to chat like normal people. This application applies speech recognition and speech synthesis
technologies to solve the communication problems of mobile chat applications for visually
impaired people. It uses speech recognition to convert speech into text. It allows users to
send messages without the need to enter text via mobile phones and uses speech synthesis to
pronounce the text so that the user can hear the incoming message. The application to be
developed will run on mobile phones in the Android operating system. The evaluation from
the sample group of 30 students at Princess Chulabhorn Science High School Phetchaburi,
is based on 2 main aspects: satisfaction in using the application and application performance.

Abstract
We enjoyed multiplayer in a sandbox game called Minecraft and used the chat function a lot,
but it was very troublesome to chat in Japanese.Because you have to switch between full-width
and half-width to chat in Japanese. It was inconvenient to switch between using half-width
characters when operating and full-width characters when chatting.Therefore, we thought it
would be convenient to create a new SNS that allows you to talk with your browser or existing
SNS, link this SNS talk with Minecraft chat, and make it possible to use the flick input you
use on your smartphone when talking. We have developed a product called NAHSNS for this
purpose.NAHSNS has not only linkage functions but also functions similar to basic message-
type SNS. You can create groups, change profiles, change chat backgrounds, reply to
messages, change text colors, and more.It's not fully functional yet, but we'd like to add
features such as voice chat, stickers, and status messages that appear on users'
profiles.NAHSNS is an SNS that we created from scratch.The server is Node.js and
TypeScript, the client is React, JSX and TypeScript, and communication between servers is
done via https.It also uses WebSockets for real-time communication.In addition to Minecraft,
NAHSNS can chat with Discord, his LINE, etc.

Abstract
This study tries to formulate an effective way to do a makeup on female faces. In order to
standardize the beauty we aim to achieve by applying makeup, we analyzed the makeups
worn by Japanese actresses on the assumption that their makeups are applied by professional
makeup artists with sufficient knowledge and skills. We conducted the analysis in two ways.
First, we classified the shapes of eyebrows based on the eyebrow shape classification table.
The result was that the most popular shape was the simple arch and the least popular was the
wide and natural arch. Second, we measured the relative heights and widths of the eyes in
the face, and the results showed that the eyes were made to look symmetrical. Based on
these results, we succeeded in calculating the ideal places where makeup should be applied
in terms of coordinates placed on the face. This suggests that we will be able to apply the
makeup that is the most appropriate for each individual’s face. We also hope our findings
will help develop a computer application that calculates how best makeup should be applied
by analyzing the face photo.

Abstract
Nowadays, rubber farmers are facing problems with the production of rubber that is not as it
should be and not worth the investment. Because rubber is a perennial plant that can produce
long-term yields. Improper care at the beginning of rubber planting may have a detrimental
effect on the rubber tree in the long run. The problem is often caused by a lack of good
knowledge and understanding of the rubber planted. We are interested in applying
technology to detect objects and classification by artificial intelligence to classify rubber
species using the unique characteristics of each rubber leaf as a classifier with Alexnet that
is available within CiRA Core and apply the resulting model for processing the rubber
classification in the application. So that rubber farmers can know the species and details of
the methods of caring for the rubber properly and get the best results.

Abstract
IoT is a very useful tool that could be used in many different field. At our school’s dormitories,
there are always flooding. While flood is coming vehicles could not pass this root but there is
no way to know if it is flooding or not, the only way is to go through that root and witness
current situation by yourself. As the fact that driving through the flood is dangerous and have
high risk for accident to happen, so facing flood is one of the decision that should not be made.
This project have the intention to decrease a chance to have accidents from both checking or
facing the flood by chance, ‘Flood Notifier’ use IoT to notify user and record water level each
day. Process of this project is it will detect current water level by water level sensor, data would
be sent and system will decide if it is flooding or not, if it is flooding the barrier will close to
prevent people from using this root but if not it will stay open and allow people to use this root.
The results is application that shown graph of water level, current water level, emergency
switch and the machine which divided into sensor part and actuator part. We anticipate our
project to help local people and we wish this could be develop further.

Abstract
Nowadays, an increasing number of people are impacted by health conditions such as
diabetes, which are connected to a high calorie diet. Fruits are better choices for widespread
consumption since people believe they are healthier. However, eating too many fruits can
lead to diabetes and other problems. Tangerines and longans are popular fruits that are
available throughout the year. This project was to invent a fruit calorie scale that indicated
weight, sugar content, and calorie information. The database sample of 100 tangerines and
140 longans was used to form the equation and write code in KidBright. The user can select
the function by pressing the switch. The fruit calorie scale will display the results of the
longans if you press the first switch, and the tangerine if you press the second switch. The
weight, sugar content, and calorie count of tangerines and longans were displayed on the
LED scale. We weighed the samples (50 tangerines and 120 longans) and compared their
weight, sugar content, and calorie count using a general scale, a brix reflectometer, and a
fruit calorie scale. According to the findings, the standard deviations for longans calculated
using the fruit calorie scale and the brix reflectometer were 7.88 and 6.21, respectively, and
the standard deviations for tangerines were 5.69 and 3.11. Similar amounts of calorie error
were calculated for tangerines and longans using brix reflectometers and fruit calorie scales:
32.28 2.63 kcal for the longans and 63.94 4.67 kcal for the tangerine. When operating a fruit
calorie scale, the user may quickly determine the weight, sugar content, and calorie count of
the fruit. This scale is also practical and reliable.

Abstract
This research shows the procedure for producing an original curved mirror, an essential
component of the omnidirectional camera used to identify a ball in the RoboCup Junior Japan
Soccer Challenge (RCJJ). This mirror was specifically designed to enable the robot to
measure relative distances and angles more accurately. First, the mirror was designed with a
conical shape using CAD. Next, the mirror was molded with Heat-Press Molding in which a
molding box is made with a CNC miller and a vinyl chloride mirror sheet is pressed to the
molding box. To measure the performance of the mirror, it was incorporated into a camera
lens and then used on a field for measurements. The measurements made by the camera and
mirror were compared to the real distances and angles between the camera and the ball.
Compared with a curved mirror, the curved mirror could make the reflected image smaller
and reflect a wider range of area around the robot to identify the ball’s location. The farthest
recognizable distance of a convex mirror was 0.9 meters while the curved mirror could
measure distances of up to 1.5 meters, approximately 1.7 times farther. This process led to
the successful production of a curved mirror able to recognize almost the entire area of the
RCJJ soccer field, which is 1.8 by 1.2 meters.

Abstract
The aim of this research is to improve the performance of the athletic club at school. Many
high school students in Japan are in the athletic club at school, and they practice everyday to
improve their performance. The performance improvement approach requires an objective
perspective with ICT in addition to practice. I belong to the swimming clubs inside and
outside school, and I want to try to improve my performance as well as other club members’,
so I started this research. In order to achieve this goal, I analyze the performance and give
different types of feedback that I thought was appropriate for school club activities, using
coaching advice methods. More specifically, I will ask high school students to practice sports
(e.g., to swim a race for swimming club team members). Then, I will compare the best score
(e.g., the swimmers race time). Also, I will record their practice using cameras to examine
how the feedback has improved their performance. As a preliminary study, I experimented at
the club team outside school. When I compared the time between two races, all the
participants (N = 5) have significantly improved their score. The result of this study indicates
that using this ICT will lead to a better sports performance improvement. One limitation is that
I haven’t yet been able to define the most suitable coaching improving the performance in
school club activities. Also, I need to conduct an experiment on the school members.

Abstract
Soil compaction work is indispensable for the development of social infrastructure.
Compaction is done with a roller as shown in Photo 1. Compaction is controlled by the
number of times of rolling compaction due to passage of rollers. The soil compacts as the
number of times of compaction progresses, but since the rollers have high rigidity, the
strength of the soil begins to decrease after a certain level. This is called over compaction.
The condition of the soil on the compacted surface is as shown in Photo 2, and it is said that
a characteristic texture appears when excessive compaction occurs. This texture is constantly
monitored by collecting images, the characteristic texture is extracted by image analysis, and
a system is created to judge signs and warn of excessive rolling compaction.

Abstract
Space debris is any human-made object in orbit that no longer serves a useful purpose. It is
a concern because even relatively small pieces can damage satellites in a collision. Since
debris at high altitudes can stay in orbit for decades or longer, it accumulates as more is
produced. Since there is currently no effective way to remove large amounts of debris from
orbit, however the authors thought the best way in this time is collect them in same place
before eliminating them. From the first study, the study to examine appropriate design for
collect the space debris, we found that the design which move by solar-sail method and
collect the debris by net. In addition, titanium, carbon fiber and aluminum were used for
made the CubeSat and found the best material is titanium because it passed in the
effectiveness of the CubeSat which is chemical analysis, technical control, environmental
and mechanical testing. Therefore, we created the controller programs for control a dynamic
of that by using the MATLAB & Simulink program, found that our CubeSat can locate the
space debris correctly and stored them in the simulation as well. In future, we forecast that
our innovation has been tested in the space.

Parabola-Shaped Solar Tracking Power Generators Compact Size

Abstract
Today, the effects of global warming have become more pronounced in many parts of the
world. Since strong winds such as typhoons have caused solar panels to be agitated and
blown away, we aim to create not only more efficient but also more endurable solar panel
devices. To prevent the solar power generators from destruction by strong winds, the
generating device must be able to be folded compactly when not in use. Taking a cue from
the metal steamer that can be freely sized, the device was equipped with a cookware, which
looks like a parabolic antenna, so that the device could track sunlight and generate electricity
efficiently. As a preliminary study, I created a device which was programmed to be able to
track sunlight automatically. In terms of compactness, the diameter of the parabola was
reduced by about 48%. However, while the solar tracking system was successful, I could not
make a perfect parabola due to the form of the steamer and could not collect light efficiently.
Besides, because I used commercially available solar panels, when the maximum amount of
electricity generated was reached, the device was unable to obtain accurate data on the
amount of electricity generated. Based on the result of the preliminary studies, it is
hypothesized that it is more efficient by making the steamer’s shape more like a parabola
and by using solar panels with a higher upper limit of power generation.

Abstract
The forest located around my community area had ever happen 22% of the forest area from
spontaneous combustion. The forest has been affected by environment and arable land
changes which has reduced the rate of plant growth, destroyed trees and made changes to the
forest structure. This has resulted in reducing the soil’s ability to absorb moisture which has
then led to soil erosion. Spontaneous combustion has adversely affected the economy
causing a reduction of National Parks revenue by reducing the number of tourists. Also,
PM2.5 particles have affected respiratory health. To address the above issues, this project
uses an KidBright board to detect heat to alert cases of spontaneous combustion.

Abstract
'Lending and Borrowing' is something that many people cannot deny that they are all familiar
with. Whether borrowing pens, pencils, or other small things from childhood, school friends,
renting books from the public library which allows you to read them without having to spend
money on it. Meanwhile, lending and borrowing often cause problems with the same issue.
Whether leased or borrowed, but not returned to the owner, items are not in their previous
state when they are returned, or even though they were gone without being returned.
Nevertheless, if you have to write a written loan agreement on a page every time, even if it's
a small loan. That might be inconvenient because it may be more difficult for both the lender
and the borrower. It is more convenient for both owner and borrower to have a proper
platform for gathering lending and borrowing things. That is why we had developed “Let Me
Lend'' to solve this problem and experiment it within our school. From the experiment, it can
be concluded that our platform “Let Me Lend'' has shown the practical example as the real
use case. Our sample group of students had used it according to their own preferences. They
are likely to find what they were looking for and can easily book it directly from the owner.
On our platform, available objects will be concluded on the dashboard. When the borrower
sends a request, it will notify the lender through Line Notify. It is for them to accept or
decline their request. As a result, it is more convenient for the real user. It can save their time
as well as their money.

Abstract
Currently, the world is thinking about universal service, like a lot of translation tools have
been developed to give us a chance to have words each other. However, they don’t much
help to communicate with hearing-impaired people. They use actually hand sign, not vocalic
language like we use, as their motherlanguage. That sometimes causes a bit of difficulties
with communicating in writing. Then we made the software, which helps to communicate
with their motherlanguage. If we type the English text on the computer, the software converts
each Alphabet to the corresponding hand shape. Additionally, the web camera can read our
hand shape, decide which letter do the hands show, and it converts the letters on the monitor.
That means, the software makes us possible to talk each other smoother, whenever and
wherever you want. Even if you don’t understand sign language. We found that there are
many kinds of hand languages all over the world. For example, there are Japanese hand sign,
Thai hand sign, national hand sign and so on. And these are completely different hand
languages for each country. This time we used national hand sign for our software which
means that we can have a conversation with hearing-impaired who knows national hand sign
and people who can use this to understand and explain things properly.
