Why not use modern technology more in the war against
COVID-19?

ABSTRACT
Recently, only the strategy of the vaccine-based herd immunity against COVID-19
has been pursued. One of the major problems is the fact that the virus continuously
mutates and it might be difficult to develop the new vaccines effective to the newly
mutated ones promptly.
As an extreme example, distributing spacesuits (100% virus invasion shielding rate)
to all people allows the government to have a means to shut down the infection at
any time. Applying the idea of herd immunity, even in a very severe infection
situation of the effective reproduction Rt = 5, if all the people wear a spacesuit in
90% of the interpersonal contact that has been done without a spacesuit, the infection
probability becomes 1/10. That means Rt = 0.5 is realized and the number of infected
people will be halved every infection period.
A prototype helmet-type mask [1], which shields 100.0% of viruses in aerosols and
is extremely comfortable, safe, and inexpensive, is developed.
We usually drink purified water rather than water taken directly from rivers and
lakes. However, as for air, we still usually breathe natural air around us without
purifying it. The main cause is that a highly-efficient, comfortable, and inexpensive
respiratory air purification device has not been available. If the mass production of
the perfect mask is realized, many people might prefer to wear the masks, regardless
of the spread of virus infection or regardless the government order to wear them.
This means the emergence of a society that is extremely resistant against all airborne
infectious diseases.

ABSTRACT
Currently, Thailand has tended to use increasing renewable energy technologies
which is green power for electricity produced to reduce the use of fossil fuels.
Mechanical energy found easily in daily life can be converted to electrical energy
using smart materials with piezoelectric properties. Piezoelectric material is found in
the form of ceramic bulk and thick film ceramic tape. Piezoelectric bulk ceramic was
fabricated using solid state reaction technique, and thick film tape ceramic was used
by the doctor blade technique. Here, the ferroelectric properties were investigated
for the dielectric constant, and polarization of switching dipoles due to different
intrinsic properties of each materials. The key factor for both types of piezoelectric
ceramics depends on their energy consumption. Bulk ceramics exhibited better
piezoelectric coefficient while require a lot of mechanical energy to convert into
electrical energy. On the other hand, the ceramic tape showed low piezoelectric
coefficient, the ceramic tape consumed mechanical energy lower than bulk ceramic
for converting energy. A technological application of piezoelectric material is
ultrasonic devices form to aid in the drying process of dried fruit that is an invention
of Center of Excellent on Alternative Energy Center, Sakon Nakhon Rajabhat
University. Piezoelectric material is expected to be an alternative energy sources for
sensor and actuator devices for future energy trend.

ABSTRACT
This presentation focuses on the government’s microcredit program titled “the
National Village and Urban Community Fund”, or for convenience, “the Thai
Village Fund” (TVF) in Thailand. The program was the largest attempt in
implementing microcredit policy because it intended to set up the loan funds from
the government grant in villages across the country in order to provide microcredit
services to reach poor people living at village level. Considering the large size of
budget which was put for the approach that was new to people concerned, it was
important that the implementation of the program was effective. Considering that the
village funds would also be one of the effective tools to get poor people or small
entrepreneur out of the economic hardship situation resulted from the COVID – 19
pandemic and the lack of concrete information on the role of the fund on this
circumstance. The main purposes of this presentation are to answer the following
questions.
1. What is microcredit and what are methodologies or models of microcredit
currently exist?
3. What are the characteristics of the TVF and, within a broad scope of microcredit
models, where is this program located in terms of its methodology?
4. What good practice can be identified from the matched model that applicable to
be used as a basis for recommending the implementation of the TVF program?
Results revealed that Microcredit or microfinance can be perceived primarily as the
provision of financial services to poor people or low-income groups who have not
traditionally been provided for. In implementing the concept, there exists a number
of distinctive methodologies or models of implementation. Each has offered its
distinct implementation features and rationales that can be used as a guide to
implement the concept. To date, there are six well-known models being operated in
the microcredit or microfinance industry: Individual Lending, Grameen Bank
Solidarity Group Lending, Latin America Solidarity Group Lending, Village
Banking, Self-reliant Village Banks and Community-Managed Revolving Loan
Fund.

The TVF could be classified within the Community- Based Organization (CBO)
lending approach and closely matched the Community-Managed Revolving Loan
Fund (CMRLF) model in which seed capital was provided as a grant to self-managed
community groups. Implementation features of the model can be divided into three
main stages. When compared the TVF implementations with rationales and
recommended practices of the model, it was found that it deviated quite clearly from
those of the model. They formed groups of people who wanted to borrow the money
rather than the lending groups of people who understood the methodology. The TVF
provided loans as rations rather as a financial service in which loan projects were
used to approve loans. Setting heavy penalties and inflexible repayment conditions
also excluded the poor from joining the program. This chain of weaknesses made the
objectives of the program difficult to attain. The program was at best the
establishment of loan funds that offer cheaper loans to villagers while creating
another cycle of debt.
It is highly recommended that each village fund provide flexible loans that meet
specific needs. Saving money should be promoted as an integral part of the program
by merging the village fund with the existing savings group. Provision of knowledge
and advisory services about the microcredit concept and the CMRLF methodology
should be organized to make such improvements possible.

ABSTRACT
Multi-composition borate / phosphate glasses with 1mol% Nd2O3 content have been
prepared using conventional melt quenching technique to study their physical,
optical properties. The physical parameters such as the density, molar volume, ion
concentration, polaron radius, inter-ionic distance and field strength were calculated
and compared with other glasses. The density was studied using toluene as
immersion liquid due to the hygroscopic nature of phosphate glasses and the
refractive index of the glass was measured using Abbe’s refractometer. X-ray
diffraction study was carried out to confirm the amorphous structure of the prepared
glass samples. The structural properties were discussed using the FTIR Spectroscopy
results. FTIR data shows the functional groups of various glass formers used in the
present glass using the beam of infrared radiations. The absorption spectra are used
to investigate the optical band gap values and structural disorder observed in
synthesised glass samples. UV-Vis-NIR absorption spectra of the glass shows
thirteen significant peaks. Thirteen well-defined absorption bands from UV–VIS
absorption spectra show the transition from the ground state (4I3/2) to several excited
states of Nd3+. The hypersensitive transition (2G7/2+4G5/2) was positioned around 581
nm. In addition, Tauc method was employed to evaluate the optical band gap
energies of the prepared glasses. Electronic polarizability of the oxide ion and optical
basicity of synthesised glasses were calculated using optical band gap and compared
with other glass samples. Analysis on Photoluminescence will be studied further.

ABSTRACT
We report a gain-switched laser oscillator configuration for generating tunable short and
narrow spectral linewidth 290 nm laser pulses from a Ce:LiCAF crystal. Continuous tuning
of the laser emission over a range of 18 nm from 281 nm to 299 nm is achieved using a
single grating in a low-Q short-cavity oscillator. The shortest pulse duration achieved is 450
ps at 281 nm and the narrowest spectral linewidth is 0.17 nm at 287 nm. The average output
energy ranged between 0.5 mJ and 0.8 mJ, resulting to conversion efficiencies of 8%–10%,
depending on the output wavelength. The simplicity of our configuration makes aligning
easier as well as reduces the loss in laser output energy, thereby leading to improved laser
efficiency.
The laser emission characteristics of Littman-grating ultraviolet Ce: LiCAF crystal lasers
pumped by the fourth harmonics of a Nd:YAG Q-switched laser at 266 nm have studied by
solving the multi-wavelength rate equations. The obtained results show that using a Littman
resonator configuration, very narrow linewidth UV laser emission (a few picometers) can be
continuously tuned over a wide spectrum from 277 to 318 nm. Furthermore, independently
tunable two-wavelength UV laser emission is also achieved by a double-Littman resonator
laser configuration using the same Ce:LiCAF crystal and pumping optics. This wavelength
region has important applications in monitoring the concentration of sulphur dioxide and
ozone in the atmosphere using differential absorption lidar which require two closely spaced
wavelengths with linewidths of 100 pm or less. The proposed scheme can be extended to
other wavelength regions using an appropriate laser gain medium, enabling other
applications requiring a tunable dual wavelength and narrow linewidth laser.

ABSTRACT
In this work, Sm3+-doped Ba-Na-B glasses with the varying of Gd3+ concentration
from 0 to 10 mol% were prepared by melt-quenching technique. The absorption
spectra show the highest peak at 402 nm (in UV-Vis region) and at 1227 nm (in NIR
region). The emission spectra, excited by 402 nm excitation wavelength, show the
high emission peaks centered at 563, 600 and 646 nm. The glass sample with 2.5
mol% of Gd3+ ions gives the highest light yield. The emission spectra, excited by
275 nm for investigation Gd3+ to Sm3+ energy transfer, show the high emission peaks
centered at 312 and 624 nm for Gd3+ ions emission and centered at 563, 600 and 646
nm for Sm3+ ions emission. The glass sample with 7.5 mol% of Gd3+ ions gives
the highest light yield because of the lower of Gd3+ to Gd3+ self-energy transfer.
The color of the emission from all glass samples are all located in orange region.

ABSTRACT
Fad diet, also called a popular diet or a diet cult that promises a dramatic result of
weight loss or other health advantages. Most of the fad diets involve getting rid of
foods that contain essential nutrients that body needs to maintain good health. Some
of these diets have had scientific support and may have shown effective weight-loss
results, such as the Atkins diet, the South Beach diet, the vegan diet, the ketogenic
diet and the intermittent fasting diet. On the other hand, many of these do not have
any solid scientific support and may develop unforeseen health problems, such as
the alkaline diet, the apple cider vinegar diet, the supplement diet, the hCG diet and
the cabbage soup diet. In order to maintain a lifelong well-being and a healthy
lifestyle, it is recommended to adopt balanced eating plans rather than to follow fad
diets. According to a panel of health experts, the overall top five of the best diet plans
in 2021 are the Mediterranean diet, the DASH diet, the Flexitarian diet, the WW diet
and the Mayo Clinic diet.

ABSTRACT
This talk investigates the evolution of network science in a nutshell. Using numerous
real-world examples, from the origins of the six degrees of separation to explaining
why networks are robust to failures and fragile to attacks at the same time. As Alber-
Laszlo Barabasi's work in network science has led to the discovery of scale-free
networks and elucidated many key network properties, from robustness to control.
Networks are everywhere, from a biological network, our genetic networks that
determine our biological existence, to the semantic networks occurring around us,
considering any distinct elements represented by nodes and the connections between
the elements or edges. Network science is the discipline at the intersection of
computer science, physics, and statistics that studies the behavior, structure,
formation, and evolution of such networks. Today, new network science concepts
and analysis tools are making isolated groups, influential participants, and
community structures visible in ways never before possible.

ABSTRACT
Despite the possibility that there are main approaches in water management,
utilization in agricultural rice planting is very important for the improvement
agricultural production and increasing of the product per Rai(area) for farmer. Water
is essential for the growth of rice and is beneficial for directional control. If the rice
receives a little amount of water, it affects the growth of the rice and the growth of
risk is low. The data analyzed for rice and water analyzes were already influenced
by various environmental factors, so the ARIMA forecast advantage would be under
that factor. The data used in this research was the average monthly rainfall from the
Hydrology and Water Management for Northern Region - Royal Irrigation
Department during January 2014 to December 2018. The time series data were
divided into two categories. The empirical study revealed the best ARIMA validated
model to be used to forecast future values for the next years. Even though such
approach mainly helps knowledge water data or forecasting future points, after the
steps of identification, estimation and verification followed here to build the suitable
ARIMA model, the results are understanding water managements and the foresight
of the causes that may influence what will happen next to the rice product of
Thailand.

ABSTRACT
Light Guide Plate(LGP) is an acrylic panel typically made from pure Polymethyl
methacrylate(PPMA) resin. PPMA is extremely transparent, highly weather
resistance and available longer than 30 years. On the bottom of the panel, a matrix
of lines can be etched, called V-Cutting, dots can be printed, a combination of both,
or particulates are added into the panel itself. The purpose of all methods is to direct
light out the front of the panel. Dot printing is a matrix of fine dots which is printed
onto the LGP using diffusive ink. These dots help scatter the light emitted from the
light source. Dot printing is a quicker and cheaper process than V-cutting however,
not always the desired method. The major disadvantage of dot printing is that ink is
less effective at refracting light and therefore not as bright. Many backlighting
applications require a very bright light that dot printing just can’t accomplish. We
propose a simple technique to scatter the light from the light source through LGP by
making a matrix of drilling holes as a concave lens all over LGP panel. This
technique with LGP can be used to mix red and blue Light Emitting Diode(LED)
light source with appropriate ratio between red and blue colour to be artificial light
for plants. Wheatgrass seeds growing results and their chlorophyll extraction results
are examined to confirm the possibility in using this technique.

ABSTRACT
We reported, for the first time, a font-based software development of braille-Thai-
English translation. By using a braille font approach, an autonomous systematic
design can be implemented in bidirectional translations including braille image to
English text, braille image to Thai text, English text to braille font, and Thai text to
braille font, respectively. Under these operations, a primary process consists of
image enhancement, dot extraction, cell segmentation and cell to code mapping,
using python-based libraries and models to provide an output of audio and a word
document. Experimentally, 5 datasets (215 input files) of verso braille dots,
translating from grade 7th homework assignments, were used to evaluate software
performance, and demonstrated technical translation of braille grade 1 and 2 with the
accuracy of 77-100% from input images of commercial scanners shown in Figure 1.
Overall, the design provides ease of use with automatic stored location and numeric
input interface with potentially upgradable lexicons. Ultimately, the system design
can be an assistive technological education tool for visually impaired students,
family members, and teachers to assess homework or self-study assignments.

ABSTRACT
Mangosteen (Garcinia mangostana Linn.) pericarp is a rich source of
phytochemicals. They are, therefore, used as a traditional medicine. This study aims
to investigate an effect of pulsed electric field (PEF)-assisted extraction of
mangosteen pericarp on total phenolic content (TPC) and antioxidant activity using
ferric reducing ability power (FRAP) assay. The study conditions were varied by
PEF intensity (4, 5 and 6 kv/cm) with 1000, 3000 and 5000 pulses. Mangosteen
pericarp macerated in water was used as a control. The study revealed that TPC value
increased with higher intensity and pulses. The highest TPC was observed, in the
pericarp extracted with 6 kv/cm and 5000 pulses, at 0.17 mgGAE/gFW. The PEF-
assisted extraction showed 425% increment compared to its untreated counterpart.
Similar trend was found with FRAP assay where the pericarp extracted with PEF (6
kv/cm, 5000 pulses) showed the highest FRAP value at 0.38 mgGAE/gFW.
Moreover, TPC value and FRAP value exhibited positive correlation with R2 0.9741.

ABSTRACT
Chitin is a natural biopolymer, which has found from crab shells, shrimp shells or
insect cuticles. It has been extracted and utilized in several industries such as
pharmaceuticals, cosmetic, food, textile, paper industry and agriculture. This
research shows new method for extraction of chitin from crab shell with an eco-
friendly process. The process has reduced using of chemical substances in the
extraction and separation process. This novel method composed of deproteinization
of crab shell and demineralization by using pineapple juice with natural acid and
natural enzyme, bromelain, instead of normally using alkaline solution and inorganic
acid. The structure, surface area and elemental analysis of extracted chitin were
investigated by using fourier transform infrared spectroscopy (FTIR), scanning
electron microscope (SEM) and energy-dispersive x-ray spectroscopy (EDX),
respectively. As a result, SEM image of chitin was shown smooth surface and
elemental analysis was shown carbon, oxygen and nitrogen with slightly different in
C/N ratio form commercial chitosan. FTIR analysis has confirmed chitin
characteristics. This could be concluded that the method is good for use in chitin
extraction form crab shell. Crab shell is a food by-product from seafood industry and
pineapple juice is a by-product from pineapple jam industry, thus the process has
potential for eco-friendly, green, and environmental-safely for up-scale production
of chitin.

ABSTRACT
This study monitored the protein digestibility efficiency by in vitro method between
commercial bromelain (Nature-health®, China) and concentrate bromelain crude
extracted from peel and crown of pineapple at various temperature and pH in high
protein aquatic animal feed. The high protein aquafeed such as shrimp feed (38%
Protein), catfish feed (25% protein), and frog feed (35% protein) were digested with
the commercial bromelain powder (Nature-health®, China) and bromelain from peel
and crown of pineapple (Bhattavia strain) as solution type at pH 3 – 9 and
temperature 25, 30 and 40oC. The results showed that the optimal temperature and
pH for protein digested by commercial bromelain were 25oC, 30oC, and 40oC at pH
6 (P<0.05) for all kinds of feed. While the optimal temperature and pH for protein
digestion by concentrate bromelain extracted were 25 oC for the smallest size of
shrimp feed (No.1) and 40oC for other feed types (P<0.05) while the optimal pH for
protein digestion was pH 6 for frog feed and shrimp feed (No.1) and pH 9 for other
groups (P<0.05). In addition, the high percentage of protein digestion with
commercial bromelain was found in shrimp feed while the protein in frog and catfish
feed was highly digested by concentrate bromelain crud extracted. In conclusion,
the commercial bromelain was suitable to digest protein in shrimp feed at pH 6 with
25 – 40 oC but concentrate bromelain was suitable for frog and catfish feed at 40oC
pH 9.

ABSTRACT
The activity concentration of 210Po in squid samples collecting from Trad, the coastal
province located in the upper Gulf of Thailand was analysed using alpha
spectrometry technique. The mature squids were sampled twice a year in dry season
and wet season for a period of 2 years during 2017-2018. Radiological parameters of
annual effective dose and excessive lifetime cancer risk due to the intake of 210Po
were evaluated. The average activity level of radionuclide 210Po in the squid samples
was 5.41 ± 0.77 Bq.kg−1ww for dry season and 7.80 ± 0.96 Bq.kg−1ww for wet
season. The assessed consequent annual effective 210Po dose for adults due to squid
consumption had an average value of 67.39 µSv.y−1, which lower than the ICRP
recommended limit of 1000 Sv.y−1. The average cancer mortality and morbidity
risks were calculated to be 1.33 × 10−6 and 1.84 × 10−6 respectively, indicate that the
probability of carcinogenic risks was negligible as proposed by WHO. Thereby, it is
concluded that squid of the upper Gulf of Thailand was radiologically safe and pose
no significant hazard to the public.

ABSTRACT
Chinda pepper (Capsicum annumm L.) is classified as a large chili pepper that is an
important economic crop of Thailand. The substance in the chili pepper responsible
for its spicy taste is capsaicin. Presently, capsicin in Chinda peppers has been
extracted for use in food and medical products. The objective of this research was to
compare the efficacy of capsaicin extraction from dried Chinda peppers in different
solvents: ethanol (95% v/v), acetone, water, and a mixed solvent of acetone and
water at a ratio of 1:1. For all treatments, the ratio of chili peppers to the solvent was
20 g:240 ml. After analyzing the amount of capsaicin with a NanoDrop
spectrophotometer, it was found that the amount of capsaicin extracted from dried
Chinda peppers by the mixed solvent, acetone, water, and ethanol (95% v/v) were
240 , 130 , 110 and 90 ppm, respectively. From the results of this research, it was
concluded that the extraction of capsaicin with a mixed solvent of acetone and water
at a ratio of 1:1 was the most effective. This due to the nearly same polarity between
capsaicin compound and the mixed solvent.

ABSTRACT
Traditionally, most farmers choose to dry their rice by the sun, which is the easiest
way to reduce the moisture content of the grain. Usually, people need to scoop the
rice into the sack; each time it takes 2-3 hours per day to store the dried rice. So, this
study is to design and build a paddy collector with screw conveyor by studying the
principles, and determine the work efficiency and evaluate the machine. This
machine can drive by using a mechanism to sweep the rice into the belt and convey
it to the sack. The test process used the speeds at 1500 2000 and 2500 rpm to collect
the paddy. The results indicated that the speed at 1500 was the suitable speed for
collecting the paddy because it has a high working capacity average and a high
working efficiency average, and a low loss. The machine can run in a low cycle used
for storing paddy rice will not scatter the rice more than a faster cycle. Moreover,
this machine is suitable for the asphalts surface, as it has a high performance average,
a high efficiency average and a low loss value than a concrete floor. Finally, the
paddy collector with screw conveyor can help in reducing storage cost and saving
work time.

ABSTRACT
How to tidy up your office table outside the premises so it only helps to make the
atmosphere at work comfortably on sighting. But also improves the working
efficiency of the staff of various units for example, nurses, soldiers and police, in
some situations, having to work outside the office. We may have to consider design
principles as well, thus optimizing the proportion of the design. And field office
tables that can be easily moved to support the use of any location for work that said
this may be able to design and size. So Curve, concave, straight, narrow parts of
various product designs. It fits the body or is suitable for field workers. The strength
of the field office table itself depends on its design, shape and use. We will choose
materials such as Aluminum mixed with wood and in conjunction with the study of
the use of such field office tables, have to weigh or not affect or not while in use,
must also experiment with design. However the strength of the structure or field
office table in addition to the choice of material type. Combined structures must also
be considered economical as well. In Thailand, there are various types of wood used
as material. In order to be able to choose the local wood that each region is used in
building the outdoor office table. For example, most of the southern regions have
rubber wood. And Central region has tamarind wood as well as we can do molded
plywood.

ABSTRACT
Green algae are a source of bioactive compounds because they can produce a wide
variety of secondary metabolites which can be extracted using various organic
solvents. This study was aimed to determine the sample preparation and extraction
methods of crude soluble polysaccharides obtained from Thai Green caviar
(Caulerpa lentillifera). Seaweeds prepared in four different forms were used as raw
materials in the preparation step and subjected to the conditioning methods including
temperature (120 C, 15 pound/inch2), extraction time (60 and 120 min) and removal
water reagent (acetone and isopropanol) using factorial design experiment. The
studies of Microbiological activity in Good Manufacturing Practice (GMPs) from
minimally processed fruit: Escherichia coli, Staphylococcus aureus, and bacteria
contamination in commercially available minimally processed fruit tissues by disk
diffusion method showed that the crude extract from the dried sample at 60 ° C was
extracted at 120 ° C for 60 minutes under a pressure of 15 pound/inch2 has the
percentage of dry matter content was significantly higher than that of other methods
(p-value <0.05). Remarkably, isopropanol had more efficient than acetone in
removal water step and the characterization of crude after water removal between
the two reagents was clearly different. Further investigation on the identification of
polysaccharides and their functional properties of isopropanol extraction has
significantly better separation efficiency than acetone. This was consistent with the
analysis of bioactive compounds that were found that crude extracts isolated from
isopropanol were significantly better than acetone.

ABSTRACT
This experiment was focused on the effect of gamma and X-ray irradiation on
antioxidant activities, total phenolic contents, mangostin contents, microbial loads
and color (Hunter color L, a, b). This study revealed the energetic effect of irradiation
at the dose 5, 10, 15 and 20 kGy. The DPPH, FRAP, total phenolic contents of both
ionizing radiation showed the inclination of nonsignificant decreasing with the dose.
The bioactive compound in term of mangostin was determined by HPLC. The
mangostin contents were not significantly decreased in different irradiation sources
and doses. In microbiological aspects, total yeast and mold from both of irradiation
sources were diminished by 1 logcycle after irradiated at 5 kGy. Irradiation induced
the color changes in L, a, b values. The advantages of X-ray irradiation was
performed the non significantly alter in a and b values, meamwhile gamma
irradiation showed the significantly change in L, a, b values after increasing the dose.
Keywords: irradiation, mangosteen peel, bioactive compound, color
